The third row seat 2 (not shown in FIG. 2) is fixed to the rear floor 6 via a fixture 7 fixed on the rear floor 6. A reinforcing center member 8 having a substantially U-shaped cross section and extending in the vehicle width direction and forming a closed space with the rear floor 6 is fixed to the lower surface of the rear floor 6 corresponding to the position where the fixture 7 is installed. ing.
As shown in FIG. 3, a storage box 10 storing a high-voltage system device such as a battery 9 </ b> A and a control device (including an inverter, a converter, etc.) 9 </ b> B is installed inside the underfloor storage recess 3.

As is well known, the hybrid vehicle 1 travels using the power of one or both of the internal combustion engine and the electric motor as a driving force. Further, in the hybrid vehicle 1, when the driving force is generated by the electric motor, electric power is supplied to the electric motor from the battery 9 </ b> A stored in the storage box 10, while the electric motor is used as a generator during deceleration or the like. The battery 9A is charged with the electric power generated by the electric motor. The control device 9B housed in the storage box 10 controls the receipt of power from the battery 9A.

In the present embodiment, the storage box 10 is made of metal, and as shown in FIGS. 5 and 7, the storage box 10 is formed in a box body 11 in which high-voltage devices such as a battery 9A and a control device 9B are stored, and the box body 11 And a lid member 13 for opening and closing the access opening 12. The box body 11 includes a box-shaped box body body portion 14 having an upper opening, and a box body top plate portion 15 fixed to the upper portion of the box body body portion 14 so as to close the upper opening of the box body body portion 14. It consists of and. As shown in FIG. 5, the access opening 12 is formed in the box body top plate portion 15 on the rear side in the longitudinal direction of the vehicle body and on the right end side.

As shown in FIG. 4, the lid member 13 is normally fastened to the box main body top plate portion 15 by bolts 90, and the access opening 12 is closed by the lid member 13 in this state. The access opening 12 is exposed by removing the bolt 90 and removing the lid member 13. As a result, the high-voltage device can be accessed through the access opening 12.

As shown in FIGS. 5 and 7, a switch 16 for switching between energization and non-energization (cutoff) of the high-voltage device is provided at the right end of the upper portion of the box main body 14. As shown in FIG. 4, the switch 16 is a switch of a type that switches between ON and OFF by tilting the movable part 16 a, and the movable part 16 a is exposed to the outside from the upper end of the box body body part 14. is doing. The switch 16 is turned on (energized state) when the movable portion 16a is tilted rearward as shown by a solid line in FIG. 4 to be in a lying position, and the movable portion 16a is shown by a two-dot chain line in FIG. Is turned off (non-energized) when the vehicle is tilted forward to a standing posture. The position of the movable portion 16a when the switch 16 is in the OFF state (non-energized state) is positioned forward of the position of the movable portion 16a when the switch 16 is in the ON state.

The shape and size of the lid member 13 are set so as to completely block the access opening 12 and to overlap with a portion of the box body top plate 15 that forms the entire periphery of the access opening 12.

In the lid member 13, an arm member 17 formed by press-molding a metal plate is fixed (welded) to the right end portion at the front end in the vehicle longitudinal direction. The arm member 17 is arranged along the upper surface of the lid member 13 and is fixed to the fixing portion 18 that is long in the vehicle width direction, and a first protruding portion that is bent upward from the left end portion of the fixing portion 18 and then bent to the left and horizontally extends. (Projecting portion) 19 and a second projecting portion 20 that is bent downward from the right end portion of the fixing portion 18 and then extends obliquely to the front right of the vehicle body and has its tip bent downward. The first protrusion 19 and the second protrusion 20 project outward from the lid member 13.
A plate (projection) 21 made of metal is welded and fixed to the left end portion of the lid member 13, and the plate 21 has a tip projecting leftward from the lid member 13.

On the other hand, a metal bracket 22 detachable from the plate 21 and a metal bracket 23 detachable from the first projecting portion 19 of the arm member 17 are welded and fixed to the box body top plate 15. ing. As shown in FIGS. 4, 9, and 10, the

brackets

22 and 23 have the same shape, and are arranged with the longitudinal direction along the longitudinal direction of the vehicle body. The

brackets

22 and 23 are a fixing portion 24 fixed to the box body top plate portion 15 and a member that is bent upward from the rear end portion of the fixing portion 24 and then extends horizontally toward the rear of the vehicle body and the tip thereof is bent downward. And a joint portion 25.

Here, as shown in FIGS. 4 and 7, when the lid member 13 of the box body top plate 15 is arranged so as to be bolted (in this case, the access opening 12 is closed by the lid member 13). The position is defined as “closed position”, and the state where the lid member 13 is located at the closed position is referred to as “closed state”.
As shown in FIGS. 4 and 7, when the lid member 13 is positioned at the closed position, the leading end portion of the plate 21 is inserted into the space 26 below the engaging portion 25 of the bracket 22. Further, the distal end portion of the first projecting portion 19 of the arm member 17 is inserted into the space 26 below the engaging portion 25 of the bracket 23. As shown in FIG. 5, when the lid member 13 is translated from the closed position to the right by a predetermined dimension, the plate 21 is pulled out from the space 26 below the engagement portion 25 of the bracket 22, and the engagement of the bracket 23 is performed. The

brackets

22 and 23 are arranged so that the first projecting portion 19 of the arm member 17 is pulled out from the space 26 below the joint portion 25.

In the present embodiment, the space 26 below the engaging portion 25 of the

brackets

22 and 23 constitutes an insertion portion into which the plate 21 or the first protruding portion 19 can be inserted.
The

brackets

22 and 23 constitute a part of the box main body 11, and the plate 21 and the arm member 17 can be regarded as constituting a part of the lid member 13. Therefore, when the tip portion of the plate 21 is inserted into the space 26 below the engaging portion 25 of the bracket 22, the arm is mounted on the space 26 below the engaging portion 25 of the bracket 22 and the plate 21 and the bracket 23. The bracket 23 and the first projecting portion 19 when the tip portion of the first projecting portion 19 of the member 17 is inserted, the box body 11 is at least of the lid member 13 when viewed from the opening direction (upward) of the access opening 12. An overlapping portion is formed in which the box body 11 and the lid member 13 overlap so as to partially cover the box body 11 from the outside.

Next, the positional relationship between the switch 16 and the second protrusion 20 of the arm member 17 will be described in detail.
As described above, when the switch 16 is in the ON (energized) state, the movable portion 16a of the switch 16 is in a posture in which it is tilted backward as shown by a solid line in FIG. Thus, when the switch 16 is in the ON state, when the lid member 13 is in the closed position, as shown in FIGS. 7 and 8, the distal end portion (contact portion) of the second projecting portion 20 of the arm member 17 is used. Part) 20a is located very close to the left side surface of the movable part 16a. Then, when the lid member 13 is horizontally moved from the closed state to the right, the distal end portion 20a of the second projecting portion 20 abuts against the movable portion 16a. That is, the switch 16 and the second protrusion 20 are arranged so as to restrict the movement of the lid member 13 to the right. Further, the plate 21 is not pulled out from the space 26 below the engaging portion 25 of the bracket 22 at the position of the lid member 13 when the distal end portion 20a of the second projecting portion 20 abuts against the movable portion 16a. The dimension is set so that the first protrusion 19 of the arm member 17 is not pulled out from the space 26 below the engaging portion 25 of the 23.

As a result, when the switch 16 is in the ON state, even if the bolt 90 is removed, the overlap between the

brackets

22 and 23 and the plate 21 and the second protrusion 20 of the arm member 17 cannot be released. Therefore, the lid member 13 cannot be moved upward, and the lid member 13 cannot be removed. That is, the interlock structure of the storage box 10 as described above prevents access to the high voltage system device accidentally while the high voltage system device stored in the storage box 10 is energized. can do.

On the other hand, as described above, when the switch 16 is in the OFF (non-energized) state, the movable portion 16a of the switch 16 stands more forward than in the ON state as indicated by a two-dot chain line in FIG. . When the lid member 13 is moved horizontally from the closed position to the right in this state, the second projecting portion 20 of the arm member 17 and the movable portion 16a of the switch 16 do not interfere with each other as shown in FIGS. Further, the switch 16 and the second protrusion 20 are disposed. Therefore, when the switch 16 is turned off, the lid member 13 can be moved horizontally to the right so that the tip 20a of the second protrusion 20 of the arm member 17 can be moved to the rear of the movable part 16a of the switch 16. . When the distal end portion 20a of the second projecting portion 20 is moved to the rear of the movable portion 16a in this way, the plate 21 is pulled out from the space 26 below the engaging portion 25 of the bracket 22, and the engagement of the bracket 23 is further increased. The dimension is set so that the first protrusion 19 of the arm member 17 is pulled out from the space 26 below the joint portion 25.
Therefore, if the switch 16 is in the OFF state, the lid member 13 is removed from the box body top plate portion 15 by horizontally moving the lid member 13 to the right and then moving the lid member 13 upward. Can do. That is, in the interlock structure of the storage box 10 described above, the lid member 13 can be removed only when the switch 16 is OFF, and the high-voltage system device stored in the storage box 10 can be accessed. .

Also, as shown in FIGS. 5 and 6, when the tip 20a of the second protrusion 20 is located behind the movable part 16a, the movable part 16a can be changed even if the switch 16 is switched from OFF to ON. The second projecting portion 20 prevents the movable portion 16a from tilting in the middle of tilting backward. For this reason, the switch 16 cannot be switched ON.

In this embodiment, the switch 16 constitutes movement restriction means. When the switch 16 is energized to the high-voltage device stored in the storage box 10, the

brackets

22 and 23 of the box body 11, the plate 21 of the lid member 13, and the first of the arm member 17 are used. The movement of the lid member 13 in the direction in which the overlap with the protruding portion 19 is eliminated is limited. On the other hand, when the energization of the high-voltage device is cut off, at least the

brackets

22 and 23 of the box body 11 and the plate 21 of the lid member 13 and the first protrusion 19 of the arm member 17 are completely overlapped from the closed state. The movement of the lid member 13 is permitted until the state is resolved.

According to the interlock structure of the storage box 10 according to the present embodiment, when the lid member 13 is in the closed state, the

brackets

22 and 23 of the box body 11, the plate 21 of the lid member 13, and the first protrusion of the arm member 17. The unit 19 is configured to overlap. Further, the movement of the lid member 13 is restricted by the movable portion 16a of the switch 16 when the switch 16 is in the ON state. Therefore, according to the interlock structure of the storage box 10 according to the present embodiment, it is possible to prevent the lid member 13 from being removed when the switch 16 is in the ON state. Moreover, the interlock with respect to the cover member 13 can be comprised with a simple structure. Further, the box body 11 and the lid member 13 are not easily restricted by the shape and the like, and are not easily restricted by the layout in the storage box 10. Further, the degree of freedom of arrangement of the overlapping portion between the box body 11 and the lid member 13 is great.

Further, the overlapping portion of the box body 11 and the lid member 13 is constituted by the overlapping of the

brackets

22 and 23 of the box body 11, the plate 21 of the lid member 13 and the first protruding portion 19 of the arm member 17. That is, since there are a plurality of overlapping portions (two locations), the opening operation of the lid member 13 can be more reliably regulated. By providing a plurality of overlapping portions, the lid member 13 can be formed of an inexpensive material having a relatively low rigidity, and the cost can be reduced.

Further, by attaching the

brackets

22 and 23 to the existing box body and providing the plate 21 and the arm member 17 on the existing lid member 13, the overlapping portion can be configured without changing the shape of the existing storage box. it can.

In addition, since the movement restricting member for the lid member 13 is constituted by the movable portion 16a of the switch 16, a member dedicated to the movement restricting member is not necessary, and the number of parts can be reduced.
Further, the first projecting portion 19 provided at one end of the arm member 17 constitutes a part of the overlapping portion, and the distal end portion 20a of the second projecting portion 20 formed at the other end of the arm member 17 is the movable portion 16a of the switch 16. The contact part with respect to is comprised. Thus, by providing the arm member 17 with two functions, the number of parts can be reduced.

<Second Embodiment>
Next, the interlock structure of the storage box according to the second embodiment of the present invention will be described with reference to the drawings of FIGS.
FIG. 11 is a plan view of the storage box in the present embodiment, and corresponds to FIG. 5 in the first embodiment.
The interlock structure of the second embodiment is different from the interlock structure of the first embodiment in that there is no bracket 23 on the box body top plate portion 15 and in the shape of the arm member 17 of the lid member 13. Also in the second embodiment, the bracket 22 and the plate 21 exist.

As shown in FIGS. 11 and 12, the arm member 17 of the lid member 13 has a step-like engagement portion 30 at the tip portion projected from the lid member 13. More specifically, the arm member 17 includes a first horizontal portion 31 that is fixed to the upper surface of the lid member 13 at one end and protrudes rightward from the lid member 13 at the distal end side. A first vertical portion (contact portion) 32 that is bent at a right angle from the tip and extends downward; a second horizontal portion 33 that is bent at a right angle from the tip of the first vertical portion 32 and extends horizontally to the left; A second vertical portion 34 bent at a right angle from the tip of the horizontal portion 33 and extending downward, and a third horizontal portion (projection) 35 bent at a right angle from the tip of the second vertical portion 34 and horizontally extended to the left It is composed of

As shown in FIG. 12, the box body body portion 14 located below the arm member 17 is provided with a rising portion (bracket) 40 that can be engaged with and disengaged from the third horizontal portion 35 of the arm member 17. . The rising portion 40 includes a standing portion 41 that stands above the box body top plate portion 15 and a horizontal portion 42 that is bent at a right angle from the upper end of the standing portion 41 and extends horizontally to the right.

In the interlock structure according to the second embodiment, when the lid member 13 is positioned at the closed position, the first vertical portion 32 of the arm member 17 is connected to the movable portion 16a of the switch 16 as indicated by a two-dot chain line in FIG. It is located further to the left than the movable portion 16a of the switch 16 in the ON state. The movable portion 16a restricts the movement of the arm member 17 to the right, that is, restricts the movement of the lid member 13 to the right. At this time, the third horizontal portion 35 of the arm member 17 is located in the space 43 below the horizontal portion 42 in the rising portion 40 of the box body body portion 14. That is, it overlaps with the horizontal portion 42 when viewed from above.

Therefore, also in the second embodiment, when the switch 16 is in the ON state, even if the bolt 90 is removed, the bracket 22 and the plate 21 overlap, and the third horizontal portion 35 of the arm member 17 and the box body. Since the overlap with the horizontal part 42 of the trunk | drum 14 cannot be cancelled | released, the cover member 13 cannot be moved upwards. Therefore, the lid member 13 cannot be removed. Thereby, in the state which energized the high voltage system device accommodated in the storage box 10, it can prevent accessing a high voltage system device accidentally.

In the interlock structure of the second embodiment, as shown by the solid line in FIG. 12, when the switch member 16 is moved to the right from the closed position when the switch 16 is in the OFF state, the arm member 17 is engaged. The part 30 can move to the right without interfering with the movable part 16 a of the switch 16. Then, as shown in FIG. 12, when the lid member 13 is moved to the right until the third horizontal portion 35 of the arm member 17 is pulled out from the space 43 below the horizontal portion 42 of the box body body portion 14, The overlap between the bracket 22 and the plate 21 and the overlap between the third horizontal portion 35 of the arm member 17 and the horizontal portion 42 of the box body body portion 14 are released.

Accordingly, also in the case of the second embodiment, the lid member 13 is removed from the box body top plate portion 15 by horizontally moving the lid member 13 to the right and then moving the lid member 13 upward. Can do. Thereby, only when the switch 16 is OFF, the lid member 13 can be removed, and the high-voltage device stored in the storage box 10 can be accessed.

In the present embodiment, the space 43 below the horizontal portion 42 of the box body body portion 14 constitutes an insertion portion into which the third horizontal portion 35 of the arm member 17 can be inserted.
The bracket 22 and the plate 21 when the tip portion of the plate 21 is inserted into the space 26 below the engaging portion 25 of the bracket 22, and the space 43 below the horizontal portion 42 of the box body body portion 14. The horizontal portion 42 and the third horizontal portion 35 when the third horizontal portion 35 of the arm member 17 is inserted into the box body 11 are for access so that the box body 11 covers at least a part of the lid member 13 from the outside of the box body 11. The box body 11 and the lid member 13 are overlapped when viewed from the opening direction (above) of the opening 12.

<Third Embodiment>
Next, a storage box interlock structure according to a third embodiment of the present invention will be described with reference to the drawings of FIGS.
In the third embodiment shown in FIG. 13, the box body top plate portion 15 is formed in an L shape in plan view, and an access opening 12 is provided at the rear right corner of the box body top plate portion 15. The lid member 13 is disposed below the box body top plate portion 15 and is attached to the box body top plate portion 15 so as to be slidable in the vehicle width direction. The lid member 13 closes the entire area of the access opening 12 in the closed position. Further, the shape and size of the lid member 13 are set so that the front end portion 13 a and the left end portion 13 b of the lid member 13 overlap the lower side of the opening edge portion 15 a of the box body top plate portion 15.

In this third embodiment, the front end 13a and the left end 13b of the lid member 13 that overlap vertically in the closed position and the opening edge 15a of the box body top plate 15 are such that the box body 11 covers at least part of the lid member 13. An overlapping portion is formed in which the box body 11 and the lid member 13 overlap each other when viewed from the opening direction (above) of the access opening 12 so as to cover from the outside of the box body 11.

And although illustration is abbreviate | omitted, similarly to 1st Embodiment and 2nd Embodiment, when the switch 16 is an ON state, the movement to the right from the closed state of the cover member 13 is controlled, OFF state Sometimes, the lid member 13 is installed so as to permit the rightward movement from the closed position (without restricting the rightward movement).

According to this configuration, when the switch 16 is in the ON state, the lid member 13 cannot be moved to the right from the closed position. Therefore, the overlap between the front end portion 13a and the left end portion 13b of the lid member 13 and the opening edge portion 15a of the box body top plate portion 15 cannot be released, and the lid member 13 cannot be removed. Thereby, in the state which energized the high voltage system device accommodated in the storage box 10, it can prevent accessing a high voltage system device accidentally.

On the other hand, when the switch 16 is in the OFF state, the lid member 13 can be moved to the right from the closed position. Therefore, the lid member 13 is moved rightward to a position where the front end portion 13a and the left end portion 13b of the lid member 13 can cancel the overlap with the opening edge portion 15a of the box body top plate portion 15, thereby the lid member 13 13 can be removed. Thereby, only when the switch 16 is OFF, the lid member 13 can be removed, and the high-voltage device stored in the storage box 10 can be accessed.

FIG. 14 is a view showing a modification of the third embodiment. In this modification, the shape of the box body top plate portion 15 is formed in a C shape (reverse U shape) having a right angle when viewed in plan, and the box body top plate portion 15 is used for access to the center right side in the front-rear direction. An opening 12 is provided, and the front end portion 13 a and the rear end portion 13 c of the lid member 13 are arranged so as to overlap the lower side of the opening edge portion 15 a of the box body top plate portion 15. The other configuration is the same as that shown in FIG.

FIG. 15 is a view showing a modification of the overlapping portion of the box body 11 and the lid member 13.
In the first embodiment described above, the plate 21 fixed to the lid member 13 is configured to overlap the lower side of the bracket 22 fixed to the box body body portion 14. However, in the form shown in FIG. 15, a stand 51 is provided upright on the box body body portion 14, and a rod 52 extending from the stand 51 in a direction approaching the lid member 13 is provided. When the lid member 13 is in the closed position, the rod 52 is positioned on the lid member 13 to restrict the upward movement of the lid member 13 and prevent the lid member 13 from being removed. Further, when the switch 16 is turned OFF and the movement of the lid member 13 from the closed position to the right is permitted, if the lid member 13 is moved to the right by a predetermined dimension, the rod 52 does not overlap the lid member 13. The lid member 13 can be moved upward and removed.

Further, as shown in FIG. 15, a bracket 53 is provided in the lid member 13, and a through hole 54 through which the rod 52 can be inserted is provided in the bracket 53, and the rod 52 penetrates the through hole 54 when the lid member 13 is closed. Then, the rod 52 may be pulled out from the through hole 54 when the lid member 13 is moved rightward.
Of course, the same configuration as described above can be applied to the overlapping portion between the first projecting portion 19 of the arm member 17 fixed to the lid member 13 and the bracket 23 fixed to the box body top plate portion 15.

<Fourth embodiment>
Next, the interlock structure of the storage box according to the fourth embodiment of the present invention will be described with reference to the drawings of FIGS.
FIG. 16 is a plan view showing a main part of a storage box according to the fourth embodiment, and FIG. 17 is a perspective view showing the main part.
The interlock structure of the fourth embodiment is different from the interlock structure of the first embodiment in the shape of the arm member 17.

Since the fixing portion 18 and the first projecting portion 19 of the arm member 17 in the fourth embodiment are the same as the arm member 17 in the first embodiment, the description thereof is omitted. The second projecting portion 20 of the arm member 17 in the fourth embodiment is bent downward from the right end portion of the fixed portion 18 and then extends to the right (right side of the drawing) in a substantially triangular shape in plan view. A right end portion (contact portion) 27a of the triangular portion 27 is bent downward. The right end portion 27a abuts on the movable portion 16a of the switch 16 in the ON state and restricts the movement of the lid member 13.

Further, at the rear end portion of the triangular portion 27, a tongue piece portion 28 is formed integrally with the triangular portion 27 so as to extend downward further so as to partially extend the right end portion 27a and then extend horizontally to the right. Yes. The tongue piece portion 28 is inserted below the movable portion 16a of the switch 16 in the ON state, and is positioned below the movable portion 16a.

In the interlock structure of the fourth embodiment, when the switch 16 is in the ON state, as soon as the lid member 13 is horizontally moved in the right direction, the right end portion 27a of the triangular portion 27 hits the movable portion 16a of the switch 16, and the lid member The rightward movement of 13 is restricted. Further, when the switch 16 is in the ON state, the tongue piece portion 28 is buried under the movable portion 16a of the switch 16, so that the tongue piece portion 28 is reliably prevented from moving above the movable portion 16a. be able to. As a result, even when the operator removes all the bolts 90 and the cover member 13 is rattled up and down (when shaken up and down), the arm member 17 of the cover member 13 moves the movable part of the switch 16. As a result, it is possible to prevent the lid member 13 from being detached from the box main body top plate portion 15.

When the cover member 13 is moved rightward when the switch 16 is in the OFF state, the triangular portion 27 and the tongue piece portion 28 of the arm member 17 and the movable portion 16a of the switch 16 do not interfere with each other. Therefore, as in the case of the first embodiment, when the switch 16 is turned off, the lid member 13 can be moved horizontally to the right. As a result, the plate 21 is pulled out from the space 26 below the engaging portion 25 of the bracket 22, the first projecting portion 19 of the arm member 17 is pulled out from the space 26 below the engaging portion 25 of the bracket 23, and the lid The member 13 can be removed from the box body top plate portion 15.

[Other Embodiments]
The present invention is not limited to the embodiment described above.
In the embodiment described above, the movement restricting means is configured by the movable portion 16a of the switch 16, but the configuration of the movement restricting means is not limited to this. For example, a lock member that restricts movement of the lid member is driven by an actuator that is driven in response to energization or non-energization of the high-voltage system device, and when the high-voltage system device is energized, the lock member is moved by the actuator. The lid member is prevented from moving by being moved to the locked position, and when the high voltage system device is in a non-energized state, the actuator is configured to move the lock member to the unlocked position to allow the lid member to move. Also good.
In the first embodiment and the second embodiment described above, two overlapping portions are provided, but three or more overlapping portions may be provided.
The electric vehicle is not limited to a hybrid vehicle, and the present invention can be applied to an electric vehicle using only a motor as a power source.

Interlock that restricts the opening operation of the lid member can be configured with a simple structure. In addition, the shape of the box main body and the lid member can be made difficult to be restricted, and the layout inside the storage box can be made difficult to be restricted. Furthermore, the degree of freedom of arrangement of the overlapping portion between the box body and the lid member can be increased.
