A water return duct is assembled inside the vent duct main body to prevent water from entering the passenger compartment.

Japanese Patent Application Laid-Open No. 2005-75020

In the structure in which the water return duct suppresses the infiltration of water as in Patent Document 1, a space for arranging the water return duct is required in front of the valve opening of the outlet valve (vent duct). Therefore, when the depth space in the cab in front of the valve opening is restricted (for example, when the depth space in the cab is narrow, or when other members are arranged in the depth space in the cab), the water return duct can not be assembled, and the intrusion of water cannot be suppressed.

Therefore, the present disclosure aims to provide a cab rear surface structure that can suppress water from entering the cab from the valve opening even when the depth space in the cab in front of the valve opening is restricted. do.

In order to achieve the above object, a first aspect of the present invention is a vehicle cab rear surface structure in which an outlet valve having a valve opening communicating between the inside and the outside of the cab is provided on the rear surface of the cab facing the front surface of the cargo bed. and left and right shield lips arranged on both sides of the outlet valve in the vehicle width direction.

Each of the left and right shield lips has a lip base portion fixed to the rear surface of the cab, and a plate-shaped lip body portion projecting rearward with the lip base portion fixed to the rear surface of the cab in a lip-mounted state. The left and right lip body portions extend vertically so as to shield the valve opening from both sides in the vehicle width direction when the lip is attached.

In the above configuration, most of the water that blows from the outside in the vehicle width direction through the space between the rear surface of the cab and the front surface of the bed toward the valve opening hits the shield lip before reaching the valve opening. difficult to reach. Therefore, when the vehicle is exposed to water from the outside in the vehicle width direction, the left and right shield lips can preferably suppress water from entering the vehicle (inside the cab) through the valve opening.

Since the left and right shield lips are fixed to the rear surface of the cab and protrude rearward, even when the depth space in the cab in front of the valve opening is restricted, the shield lips can suppress the intrusion of water.

A second aspect of the present invention is the cab rear surface structure of the first aspect, wherein the lip main body portion is formed of an elastic material and extends obliquely rearward toward the opposite valve opening side away from the valve opening when the lip is attached. Extend.

In the above configuration, the lip body portion extends obliquely rearward toward the side opposite to the valve opening. side is less likely to warp toward the valve opening side. Therefore, it is possible to reliably prevent water from entering through the valve opening.

In addition, since the lip body is made of an elastic material, even if the lip body interferes with the front surface of the cargo bed, the front surface of the cargo bed is less likely to be damaged.

A third aspect of the present invention is the cab rear surface structure of the second aspect, wherein the shield lip includes an edge portion opposite to the opening side located at the end portion of the lip base portion opposite to the valve opening side when the lip is attached; It has a small lip portion projecting from the opposite opening side edge to the opposite valve opening side and overlapping with the rear surface of the cab. A lip body portion extends from the edge opposite the opening. The main lip portion, the edge portion opposite to the opening side, and the small lip portion are integrally formed of an elastic material. The small lip portion in the lip attached state is held in a state of being elastically deformed rearward by contact with the rear surface of the cab.

In the above configuration, the small lip portion in the lip attached state is held elastically deformed rearward, so that the shield lip has a restoring force to direct the main lip portion toward the side opposite to the opening. Therefore, it is possible to further prevent the rear end side of the lip main body portion from warping toward the valve opening side.

A fourth aspect of the present invention is the cab rear surface structure according to the second or third aspect, wherein the lip main body portion is in a normal state where the lip is attached and does not receive a pressing force toward the valve opening side. It is set to a length that allows contact with the front surface of the loading platform by elastically deforming due to the pressure applied to the valve opening side without contacting the valve opening side.

In the above configuration, when a pressure force from water directed toward the valve opening is received, the lip body abuts against the front surface of the cargo bed, and the shield lip blocks the space between the rear surface of the cab and the front surface of the cargo bed. It is possible to more preferably suppress the intrusion of water from the

If the lip body is in contact with the front surface of the bed under normal conditions (normal state) when there is no pressing force from water, etc., the lip body and the front surface of the bed will rub against each other due to vibrations while the vehicle is running, Damage such as paint peeling may occur. On the other hand, the lip main body of this aspect is normally separated from the front surface of the loading platform and can abut against the front surface of the loading platform when subjected to a pressing force. Such damage can be suppressed.

A fifth aspect of the present invention is the cab rear surface structure of the fourth aspect, wherein the tip end side of the lip body portion is inclined more toward the side opposite to the valve opening than the base end side.

In the above configuration, the front end (rear end) of the lip body is inclined more toward the side opposite to the valve opening than the base end (front end). It is possible to reliably prevent the front end side of the lip main body portion from warping toward the valve opening side after contact.

According to the present disclosure, even when the depth space in the cab in front of the valve opening is restricted, it is possible to suppress water from entering the cab through the valve opening.

The upper and lower partition plate portions 13 and 14 face each other vertically inside the duct portion 12 and extend in the vehicle width direction to connect the inner surfaces of the left and right side walls 17 of the duct portion 12 . A rear edge of the frame body 11 defines a rectangular valve opening 18 . The valve opening 18 is divided into three upper and lower stages (an upper valve opening 19, a middle valve opening 20, and a lower valve opening 21) by the upper and lower partition plates 13 and 14. As shown in FIG. The valve openings 19 , 20 , 21 of each stage are in the shape of a rectangle whose width in the vehicle width direction is longer than its vertical width, and are located between the inside (inside the vehicle) and the outside (the rear surface 4 of the cab and the front surface 6 of the cargo bed) of the cab 2 . space outside the vehicle).

The stopper portion 15 includes an upper stage area arranged in front of the upper stage valve opening 19, a middle stage area arranged in front of the middle stage valve opening 20, and a lower stage area arranged in front of the lower stage valve opening 21. Each region of the stopper portion 15 is inclined rearward and downward (see FIG. 3). Peripheral edge portions of respective regions of the stopper portion 15 are fixed to the duct portion 12 and the partition plate portions 13 and 14 to reinforce the duct portion 12 and the partition plate portions 13 and 14.

The cab back panel 3 is formed with a rectangular valve mounting hole 7 (see FIGS. 3 and 5B) that is slightly larger than the outer shape of the duct portion 12 and smaller than the outer shape of the frame portion 11. The outlet valve 1 is fixed to the cab back panel 3 (the cab rear surface 4) by inserting the duct portion 12 into the valve mounting hole 7 from the rear (from the side of the cargo bed front surface 6). In this embodiment, a total of six locking projections 22, two pairs of top and bottom and one pair of left and right, are projected forward from the front surfaces of the upper, lower, left, and right frame portions 11 of the duct portion 12 (see FIG. 4). As the duct portion 12 is inserted into the valve mounting hole 7, the upper, lower, left, and right locking projections 22 are locked to the upper, lower, left, and right peripheral edge portions of the valve mounting hole 7 (see FIG. 5B), thereby opening the outlet valve 1. is fixed to the cab rear surface 4. In this valve mounted state, the sealing material 9 is interposed between the front surface of the frame portion 11 and the cab rear surface 4 , and the space between the frame portion 11 and the cab rear surface 4 is sealed by the sealing material 9 . Note that the outlet valve 1 may be fixed to the cab rear surface 4 by other methods (for example, fastening with bolts, etc.).

As shown in FIG. 3, the water receiver 16 has a rectangular box shape with an open top. The bottom plate 23 and left and right side plates 24 of the water receiving portion 16 extend forward continuously from the duct portion 12 , and the lower end portion of the duct portion 12 constitutes the rear end portion of the water receiving portion 16 . The upper surface of the bottom plate 23 constitutes a drainage bottom surface 25 , and the drainage bottom surface 25 is arranged below the partition plate portions 13 and 14 and the stopper portion 15 . The drain bottom surface 25 is inclined rearward and downward so that water can easily flow toward the lower valve opening 21 .

The baffle 30 is a thin plate-like elastic body made of a flexible material such as rubber. As shown in FIGS. 20 is provided with a middle baffle 32, and the lower valve opening 21 is provided with a lower baffle 33, respectively. The width of the upper and middle baffles 31 and 32 in the vehicle width direction is substantially equal to the width of the lower baffle 33, and the vertical width of the upper and middle baffles 31 and 32 is the same as the height of the lower baffle 33. Almost equal.

Each baffle 30 is supported by the upper edges of the valve openings 19, 20, and 21 so as to close the upper valve opening 19, the middle valve opening 20, and the lower valve opening 21, respectively, and hang obliquely downward to the rear. , the forward displacement (tilting) from the closed position that closes the valve openings 19, 20, 21 is prevented, and the closed position that closes the valve openings 19, 20, 21 is pushed from the front to move backward (outside the cab). to open the valve openings 19, 20, 21. In this embodiment, as shown in FIG. 5(a), each baffle 30 (in the example of FIG. 5(a), the baffle 32 in the middle stage) integrally protrudes from the upper edge of the arrowhead-shaped engagement in plan view. The projecting portion 34 is inserted from below into the baffle locking hole 26 formed in the upper edge portion of the valve openings 19, 20, 21 (the upper partition plate portion 13 in the example of FIG. 5A), and the locking projection By locking the portion 34 to the baffle locking hole 26 (locking the head of the locking projection 34 to the peripheral edge of the baffle locking hole 26), the baffle 30 is supported by the valve body 10 and hangs down. . Four baffle locking holes 26 are arranged at substantially equal intervals in each stage, and each baffle 30 is supported at four positions. Note that the method for supporting the upper end of the baffle 30 is not limited to the above, and other methods (for example, fastening with bolts, fixing with an adhesive, etc.) may be used.

Each baffle 30 hangs obliquely downward along the rear surface of the stopper portion 15 to close the valve openings 19, 20, and 21 (closed position) in a normal state in which no external force is applied, and the stopper portion 15 is in the closed position. prevent the baffle 30 from tilting forward from the That is, the baffle 30 allows air to flow from inside the cab 2 to outside the cab 2 and prevents air from moving from outside to inside the cab 2 .

As shown in FIG. 2, left and right shield lips 40 are attached to the rear surface 4 of the cab. The left and right shield lips 40 are arranged on both sides (left and right) of the outlet valve 1 in the vehicle width direction, and extend downward from the lower end of the valve opening 18 (lower edge of the lower valve opening 21). It extends linearly in a substantially vertical direction to above the upper edge of the opening 19).

As shown in FIGS. 2, 3 and 6, each of the left and right shield lips 40 includes a flat lip base portion 41 fixed to the cab rear surface 4 and a lip attachment portion 41 having the lip base portion 41 fixed to the cab rear surface 4 . A plate-like lip main body 42 protruding rearward in the lip attached state, and an opposite opening side edge portion 43 (Fig. 6), and a small lip portion 44 (see FIG. 6) that protrudes from the non-opening side edge portion 43 to the non-valve opening side and overlaps the cab rear surface 4. The lip body portion 42 has the non-opening side edge It protrudes and extends from the portion 43 . The lip base portion 41, the lip body portion 42, the opposite opening side edge portion 43, and the small lip portion 44 of the present embodiment are integrally formed of an elastic material (for example, a rubber material such as thermoplastic elastomer (TPE)). .

Clips 50 protruding from the front surface of the lip base 41 are attached to a plurality of positions (three upper, middle and lower positions in this embodiment) of the lip base 41, and clip insertion holes 8 formed in the cab back panel 3 (see FIG. 6). ), the clip 50 is inserted from the rear and locked to the front surface of the cab pack panel 3 . The upper clip 50 is positioned above the upper end of the valve opening 18 and the lower clip 50 is positioned below the lower end of the valve opening 18 .

The left and right lip body portions 42 extend vertically so as to shield the valve opening 18 from both sides in the vehicle width direction when the lips are attached. The lip body portion 42 extends obliquely rearward toward the opposite side of the valve opening away from the valve opening 18 in the lip attached state. The lip main body 42 does not come into contact with the loading platform front face 6 in a normal state (indicated by a solid line in FIG. 6) in which the lip is attached and is not subjected to a pressing force toward the valve opening 18 from the outside in the vehicle width direction. , and is elastically deformed by a pressing force toward the valve opening side, so that the length is set so that it can come into contact with the loading platform front surface 6 (indicated by a chain double-dashed line in FIG. 6). Further, the lip body portion 42 is not flat, but is bent such that the tip side thereof is inclined more toward the side opposite to the valve opening than the base end side.

The small lip portion 44 in the lip-attached state is elastically displaced rearward from the state before being attached to the cab rear surface 4 due to contact with the cab rear surface 4 (displaced from the state indicated by the broken line in FIG. 6 to the state indicated by the solid line). , is held in such a state.

The cab back panel 3 of this embodiment has an uneven shape in which a convex portion that protrudes rearward and a concave portion that is concave forward are arranged along the vehicle width direction, and the lip base portion 41 is formed on the convex portion of the cab back panel 3. It is fixed, and the small lip portion 44 protrudes obliquely forward along the boundary between the convex portion and the concave portion.

According to the present embodiment, the rapid increase in air pressure inside the cab 2 when the door (not shown) of the cab 2 is closed is suppressed by the outflow of air from the outlet valve 1 . Therefore, the closing operation of the door can be performed smoothly.

Most of the water (indicated by white arrows in FIG. 6) blowing in the vehicle width direction toward the valve opening 18 passing between the cab rear surface 4 and the loading platform front surface 6 from the outside in the vehicle width direction reaches the valve opening 18. Since it hits the shield lip 40 before it reaches the valve opening 18, it is difficult to reach it. Therefore, when the vehicle is exposed to water from the outside in the vehicle width direction, the left and right shield lips 40 can preferably prevent water from entering the vehicle interior (inside the cab 2 ) through the valve opening 18 .

Since the left and right shield lips 40 are fixed to the rear surface 4 of the cab and protrude rearward, even if the depth space 51 (see FIG. 3) in the cab in front of the valve opening 18 is restricted, the shield lips 40 Intrusion of water can be suppressed.

Since the lip body portion 42 extends obliquely rearward toward the side opposite to the valve opening, when the lip body portion 42 receives a pressure force from the water toward the valve opening side, the rear end side of the lip body portion 42 is inclined. Hard to warp to the valve opening side. Therefore, it is possible to reliably prevent water from entering through the valve opening 18 .

Since the lip main body part 42 is made of an elastic material, even if the lip main body part 42 interferes with the front surface 6 of the loading platform, the loading platform front surface 6 is unlikely to be damaged.

Since the small lip portion 44 in the lip-attached state is elastically deformed rearward, the shield lip 40 in the lip-attached state has a restoring force to direct the lip body portion 42 toward the opposite opening side. Therefore, it is possible to further prevent the rear end side of the lip body portion 42 from warping toward the valve opening side.

When the lip main body portion 42 abuts against the loading platform front surface 6 when receiving pressure from water directed toward the valve opening side, the gap between the cab rear surface 4 and the loading platform front surface 6 is blocked by the shield lip 40. Intrusion of water from the opening 18 can be more suitably suppressed.

If the lip main body 42 is in contact with the loading platform front surface 6 in a normal state (normal state) when the lip main body 42 is not subjected to pressure from water or the like, the lip main body 42 and the loading platform front surface 6 rub against each other due to vibrations or the like while the vehicle is running. , there is a risk that the front surface 6 of the loading platform may be damaged, such as peeling of paint. On the other hand, the lip main body 42 of the present embodiment is normally separated from the front surface 6 of the loading platform and can come into contact with the front front surface 6 of the loading platform when the pressing force is applied. It is possible to suppress damage such as peeling of paint on the loading platform front surface 6 .

In addition, since the tip side (rear end side) of the lip main body 42 is inclined more toward the anti-valve opening side than the base end side (front end side), the lip main body portion 42 receives the pressing force from the water moving toward the valve opening side and moves toward the loading platform front surface 6 . It is possible to reliably prevent the front end side of the lip body portion 42 from warping toward the valve opening side after contact.

Although the present invention has been described above based on the above embodiments, the present invention is not limited to the contents of the above embodiments, and can be appropriately modified without departing from the scope of the present invention. In other words, all other embodiments, examples, operation techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.

For example, in the above embodiment, the case where the valve openings 19, 20, 21 are arranged vertically in three stages was described, but the number of valve openings may be in one stage, or in a plurality of stages other than three stages. Moreover, although the three-stage valve openings 19, 20, and 21 have substantially the same shape, the shape of the valve openings may be different between the stages.

In the above embodiment, the lip base portion 41, the lip body portion 42, the edge portion 43 on the side opposite to the opening, and the small lip portion 44 are formed integrally with an elastic material. Not limited. For example, the lip base portion, the lip body portion, the edge portion opposite to the opening side, and the small lip portion may be integrally formed of a non-elastic material (for example, hard resin). , the opposite opening side edge portion and the small lip portion may be integrally formed with an elastic material and fixed to the lip base portion.
