Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.

The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.

Fig. 1 is a view of an unmanned distribution vehicle provided in an embodiment of the present disclosure, which may specifically include a vehicle body and a shelf 1 disposed on the vehicle body. The vehicle body is at least used for bearing the goods shelf 1, and the vehicle body can transport goods under the management of the unmanned distribution control system so as to deliver the goods in the goods shelf 1 to a destination. The shelf 1 may comprise at least one receiving space for goods.

As shown in fig. 2a to 2f, the shelf 1 in the embodiment of the present specification may include a support assembly, a frame assembly 2 and a bracket assembly which are cooperatively arranged. Wherein the bracket assembly includes a bracket body 31 and a first slider 32 connected to the bracket body 31. The pallet body 31 can be loaded with goods.

The frame assembly 2 may include a frame body 21 and a first rail 22 provided on the frame body 21, the first rail 22 for defining a movement path of the first slider 32, and the first slider 32 may be reciprocally slid along the first rail 22. In the illustrated embodiment, the relative position between the bracket body 31 connected to the first slider 32 and the first rail 22 can be adjusted by adjusting the relative position between the first slider 32 and the first rail 22, so as to adjust the position and size of the accommodating space in the extending direction of the first rail 22 (e.g., the height direction of the unmanned distribution vehicle), so that the accommodating space can be applied to various goods with different sizes in the extending direction, and provide a more flexible placement position for the goods.

In the present specification, the first slider 32 may be detachably coupled to the carriage body 31, and the assembly between the first slider 32 and the carriage body 31 may be performed after the assembly between the first slider 32 and the first rail 22 is completed.

Wherein, the support assembly may include a support body and a second rail 11 disposed on the support body, and an extending direction of the second rail 11 is different from an extending direction of the first rail 22. Also, the frame assembly 2 may further include a second slider 23 fixed to the frame body 21, and the second slider 23 may be reciprocally slid along the second rail 11. In the illustrated embodiment, the relative positions of the frame assembly 2 and the bracket assembly disposed on the frame assembly 2 and the first rail 22 can be adjusted by adjusting the relative position of the second sliding block 23 sliding on the second rail 11, so as to adjust the position and size of the accommodating space in the extending direction of the second rail 11 (for example, the width direction or the length direction of the unmanned distribution vehicle), so that the accommodating space can be adapted to various goods with different sizes in the direction, and provide more flexible placement positions for the goods.

The unmanned delivery vehicle described in this specification will be described in detail below.

As shown in fig. 2a to 2c, the frame body 21 in the embodiment of the present disclosure may have a rectangular frame structure, a set of opposite sides of the frame body 21 may be respectively provided with the first tracks 22, and two parallel tracks are respectively located on the opposite sides of the frame body 21, so that one bracket assembly may include two first sliders 32, the first sliders 32 are arranged in one-to-one correspondence with the first tracks 22, and the bracket body 31 may reciprocate along the extending direction of the first tracks 22 in the plane formed by the two first tracks 22 through the two first sliders 32. The first rail 22 may be provided at opposite sides of the frame body 21 extending in the height direction of the unmanned distribution vehicle.

In order to facilitate the user to assemble and disassemble the first slider 32 and the first rail, a mounting groove 24 penetrating the first rail 22 may be provided at a position of the frame body 21 adjacent to the end of the first rail 22. The user can effect the installation or removal of the first slider 32 of the first rail 22 on the left side of the frame assembly to the right of the orientation shown in fig. 2 b. The number of the mounting grooves 24 may be two, and the two mounting grooves 24 correspond to two ends of the same first rail 22, respectively. The extending direction of the mounting groove may be the same as the extending direction of the frame body 21.

Also, the second slider 23 may be disposed at the position of the corner of the rectangular frame and at least partially embedded in the frame body 21 such that the outer peripheral side of the first slider body 321 of the second slider 23 and the outer peripheral side of the frame body 21 are flush with each other at corresponding positions.

The support assembly may comprise two parallel arranged second rails 11. The extending direction of the first rail 22 may be perpendicular to the extending direction of the second rail 11. The following description is only given of a case where the first rail 22 may be disposed in the vertical direction and the second rail 11 may be disposed in the horizontal direction, and in other embodiments, the first rail 22 may be disposed in the horizontal direction and the second rail 11 may be disposed in the vertical direction.

In an alternative embodiment of the present disclosure, the second sliders 23 are disposed corresponding to the second tracks 11 one by one, so that the frame body 21 can be moved back and forth along the extending direction of the second tracks 11 in the plane formed by the two second sliders 23 and the two second tracks 11. Or, the supporting assembly may include four second rails 11 disposed in parallel, two of the second rails 11 correspond to the two second sliding blocks 23 disposed at the top end of the frame body 21 one by one, and the other two second rails 11 correspond to the two second sliding blocks 23 disposed at the bottom end of the frame body 21 one by one. The shelf assembly 2 may include two frame bodies 21 arranged along the extending direction of the second rail 11, and a first rail 22 is provided on each frame body 21. The space between the two frame bodies 21 may correspond to at least one receiving space arranged along the extending direction of the first rail 22.

Also, a second slider 23 is fixed to each frame body 21 in the illustrated embodiment at a position corresponding to the second rail 11, so that each frame body 21 can slide along the second rail 11 to adjust the relative position of the frame body 21 and the second rail 11. The unmanned distribution vehicle in the embodiment of the present disclosure can adjust the size of each accommodating space in the extending direction of the second rail 11 and the relative position of each accommodating space and the second rail 11 by adjusting the relative position of each frame body 21 and the second rail 11.

Optionally, the pallet 1 comprises at least two frame assemblies 2, the at least two frame assemblies 2 being arranged along the second track 11.

In an alternative embodiment of the present disclosure, the first rails 22 on different frame bodies 21 in the same frame assembly 2 are disposed opposite to each other, for example, the first rail 22 of one frame body 21 in the same frame assembly 2 is opposite to the first rail 22 of another frame body 21 in the extending direction of the second rail 11, so that the portions of the first rails 22 and the first sliders 32 on different frame bodies 21 in the same frame assembly 2, which are matched with each other, can face each other, and then the first sliders 32 corresponding to the different frame bodies 21 in the same frame assembly 2 are located between the different frame bodies 21.

The bracket assembly in this specification may include two bracket bodies 31 and different first sliders 32 to which the two bracket bodies 31 are respectively connected, and the two bracket bodies 31 are mutually matched to define at least a position of a bottom surface of the accommodating space in an extending direction of the first rail 22, for example, in a case where the first rail 22 extends in a vertical direction, the bracket bodies 31 can define at least a distance of the accommodating space from the vehicle body in the vertical direction. The distance of the two mutually cooperating bracket bodies 31 in the bracket assembly from the second rail 11 can be adjusted by the first sliders 32 respectively provided on the bracket bodies 31 so that the two bracket bodies 31 in the same bracket assembly are directly opposite in the extending direction of the second rail 11, i.e. the two mutually cooperating bracket bodies 31 in the same bracket assembly are located in the same horizontal plane.

Alternatively, the shelf 1 may include at least two bracket assemblies arranged along the extending direction of the first rail 22 to divide the shelf 1 into at least two accommodating spaces in the extending direction of the first rail 22.

In an alternative embodiment of the present disclosure, as shown in fig. 3, the first track 22 may include a first guide surface 221 and a second guide surface 222 disposed opposite to each other. The first slider 32 may include a first slider body 321, a first roller 322, and a second roller 323. The space defined between the first guide surface 221 and the second guide surface 222 may accommodate at least portions of the first roller 322 and the second roller 323 and provide a space required for rolling, assembling, and disassembling the first roller 322 and the second roller 323. Also, the first guide surface 221 and the second guide surface 222 may abut against the rolling surface of the first roller 322 and/or the second roller 323, so that the first roller 322 and/or the second roller 323 may roll along the first guide surface 221 and/or the second guide surface 222.

As shown in fig. 4a to 4c, the relative position of the first roller 322 and the first slider body 321 is adjustable, so that the distance between the first roller 322 and the first guide surface 221 is adjustable. Specifically, the first roller 322 is reciprocally movable between the first position and the second position of the first slider body 321 in a direction toward the second guide surface 222 along the first guide surface 221.

For example, when the first roller 322 is adjusted to the second position under the condition that the distance from the first position to the first guide surface 221 is smaller than the distance from the second position to the first guide surface 221, and the wheel body of the first roller and the wheel body of the second roller have the same size and shape, a view corresponding to a viewing angle along the extending direction of the first rail 22 of the first slider 32 is shown in fig. 4c, and at this time, projections of the first roller 322 and the second roller 323 in a plane perpendicular to the extending direction of the second rail 11 are overlapped. When the first roller 322 is adjusted to the first position, the first roller 322 contacts with the first guide surface 221 and can roll along the first guide surface 221, so that the first roller 322 can be used to assist in adjusting the relative position of the bracket body 31 and the first rail 22 in the extending direction of the first rail 22. Under the condition that the wheel body of the first roller and the wheel body of the second roller are the same in size and shape, the first roller 322 is adjusted to the first position, and a view corresponding to the view of the first slider 32 along the extending direction of the second track 11 is shown in fig. 4 b. At this time, the first roller 322 is closer to the first guide surface 221 of the first rail 22 than the second roller 323. The projections of the first roller 322 and the second roller 323 in a plane perpendicular to the extending direction of the first rail 22 are not coincident.

When the first roller 322 is located at the second position, the first roller 322 is no longer in contact with at least the first guide surface 221, so that a certain gap is left between the first roller 322 and the first guide surface 221, and the first roller 322 and the second roller 323 can be released from the space defined between the first guide surface 221 and the second guide surface 222, so as to release the fit between the first pulley and the first guide rail.

Furthermore, in an alternative embodiment of the present disclosure, when the first roller 322 is located at the second position, the first roller 322 may further contact neither the first guide surface 221 nor the second guide surface 222.

As shown in fig. 2d and fig. 4a to 5, the first slider 32 may further include a first installation adjustment mechanism 324, the first installation adjustment mechanism 324 is connected to the first roller 322, and the first installation adjustment mechanism 324 is adjusted to enable the first roller 322 to move back and forth between the first position and the second position of the first slider body 321.

Specifically, the first roller 322 may include a roller body 322a, a wheel axle (not shown), and an adjusting member 322b, the roller body 322a is sleeved on the wheel axle and can rotate around the wheel axle, and when the first roller 322 is in the first position, an outer peripheral side of the roller body 322a (i.e., a rolling surface of the roller body 322 a) is in contact with the first guide surface 221. One end of the wheel shaft away from the wheel body 322a is fixedly connected with the adjusting piece 322 b.

The first mounting adjustment mechanism 324 is connected to the adjustment member 322b, so that the relative position between the first roller 322 and the first slider body 321 can be adjusted by adjusting the first mounting adjustment mechanism 324. For example, the first mounting adjustment mechanism 324 is rod-shaped, the axial direction of the first mounting adjustment mechanism 324 is parallel to a connection line between the first position and the second position, a connection hole (not shown in the figure) penetrating through the first mounting adjustment mechanism 324 b along the axial direction of the first mounting adjustment mechanism 324 is formed in the adjustment piece 322b, matching threads are formed on the outer peripheral side of the first mounting adjustment mechanism 324 and the inner peripheral side of the connection hole, and the first mounting adjustment mechanism 324 is fixed to the first slider body 321 in the axial direction, so that the first mounting adjustment mechanism 324 is rotated clockwise or counterclockwise along the axial direction of the first mounting adjustment mechanism 324, and the adjustment piece 322b can be moved to the first position or the second position along the axial direction of the first mounting adjustment mechanism 324.

As shown in fig. 4d, the first slider body 321 may further include a first adjustment hole 321a, and the first adjustment hole 321a may penetrate the first slider body 321 in an extending direction of the axle (i.e., an axial direction of the first roller 322). At least a portion of adjusting member 322b is fitted into first adjusting hole 321a, and a dimension of first adjusting hole 321a in a direction of a line connecting between the first position and the second position is larger than a dimension of adjusting member 322b in the direction; the dimension of first adjustment hole 321a in the direction in which first rail 22 extends is slightly larger than the dimension of adjustment member 322b in that direction. When the first roller 322 is adjusted between the first position and the second position, the first adjusting hole 321a can provide a guiding function for adjusting the first roller 322 in a direction of a connecting line between the first position and the second position, and can provide a limiting function for adjusting the first roller 322 in an extending direction of the first rail 22, thereby improving the stability of adjusting the first roller 322.

In an alternative embodiment of the present disclosure, as shown in fig. 2d and 5, the first installation adjustment mechanism 324 can be inserted into the first adjustment hole 321a along a line between the first position and the second position, and is connected to at least a portion of the adjustment member 322b located in the first adjustment hole 321a, so that the first installation adjustment mechanism 324 can be limited in the radial direction of the first installation adjustment mechanism 324 by the first slider body 321. The end of the first mounting adjustment mechanism 324 away from the second roller 323 is provided with a protrusion for the adjustment tool to hold or a groove for the adjustment tool to engage with, so that the end can adjust the first mounting adjustment mechanism 324, so that the first mounting adjustment mechanism 324 can rotate in a fixed position relative to the first slider body 321. Specifically, the first mounting adjustment mechanism 324 is a threaded pin.

The second roller 323 in the embodiment of the present disclosure may be fixedly disposed on the first slider body 321, and the second roller 323 abuts against the second guide surface 222 and can roll along the second guide surface 222. The first roller 322 and the second roller 323 are disposed on a side of the first slider body 321 facing the first rail 22. The wheel body of the second roller 323 and the wheel body 322a of the first roller 322 may have the same shape and size. The end surface of the second roller 323 adjacent to the first slider body 321 and the end surface of the first roller 322 adjacent to the first slider body 321 are located in the same plane.

Alternatively, the number of the second rollers is at least two, and at least two second rollers 323 are respectively disposed at both sides of the first roller 322 along the extending direction of the first guide rail 22.

As shown in fig. 3, a cross section of the first guide surface 221 of the first rail 22 in a direction perpendicular to the extending direction of the first rail 22 is an arc, and a cross section shape of the first roller 322 in an axial direction of the first roller 322 matches the arc, so that after the first roller 322 is adjusted to the first position, the first guide surface 221 can limit the first roller 322 in the axial direction of the first roller 322, and the first roller 322 is prevented from falling out of the first rail 22; after the first roller 322 is adjusted, the position between the first roller 322 and the first guide surface 221 of the first rail 22 is released, and the first roller 322 can be disengaged from the first rail 22.

As shown in fig. 4a to 5, in an alternative embodiment of the present disclosure, the first slider 32 may further include a first positioning mechanism 326, and the first positioning mechanism 326 is used for positioning between the first slider 32 and the first track 22. After adjusting the first slider 32 to the target position of the first rail 22, the first positioning mechanism 326 is adjusted to fix the relative position between the first slider 32 and the first rail 22.

The relative position of the first positioning mechanism 326 and the first slider body 321 is adjustable, so that the distance between the first positioning mechanism 326 and the first guide surface 221 is adjustable. Specifically, the first positioning mechanism 326 is capable of reciprocating between the fifth position and the sixth position of the first slider body 321 in a direction toward the second guide surface 222 along the first guide surface 221.

For example, the distance of the fifth position from the first guide surface 221 is smaller than the distance of the sixth position from the first guide surface 221. When the first positioning mechanism 326 is adjusted to the fifth position, the first positioning mechanism 326 contacts the first guide surface 221 and maintains a relatively fixed position with the first guide surface 221 by the action of friction; when the first positioning mechanism 326 is located at the sixth position, the first positioning mechanism 326 is not in contact with the first guide surface 221 and the second guide surface 222, and the positioning between the first slider body 321 and the first guide surface 221 is released.

In addition, the profile of the side of the first positioning mechanism 326 facing the first guide surface 221 matches the profile of the cross section of the first guide surface 221 in the direction perpendicular to the extension direction of the first rail 22, so as to increase the contact area between the first positioning mechanism 326 and the first guide surface 221 and increase the maximum static friction force therebetween. For example, the profile of the side of the first positioning mechanism 326 facing the first guide surface 221 and the profile of the first guide surface 221 in a cross section perpendicular to the extending direction of the first rail 22 are arc shapes that are matched with each other. The first positioning mechanism 326 may be made of aluminum alloy.
