Figures 1-3

[0036] As some embodiments of the present application, the storage vehicle 100 according to an embodiment of the present application is shown in FIG. 2, which includes a vehicle body 10, a driving mechanism 40, a bearing support 20, and a walking wheel 50. The driving mechanism 40 is arranged on the vehicle body 10. The bearing support 20 is rotatably arranged on the driving mechanism 40. The driving mechanism 40 can drive the bearing support 20 to move along the height direction of the vehicle body 10. The walking wheel 50 is arranged at the lower end of the vehicle body 10. Figure 2 ​As shown, the vehicle body 10 of the buffer vehicle 100 can include a first frame 101 and a second frame 102, wherein the first frame 101 is perpendicular to the moving plane of the buffer vehicle 100, the second frame 102 is parallel to the moving plane of the buffer vehicle 100, and the first frame 101 is connected to one end of the second frame 102, that is, the first frame 101 and the second frame 102 are arranged in the shape of "L". The first frame 101 and the second frame 102 are fixed by welding or bolt connection, or the first frame 101 and the second frame 102 are integrally formed.

[0037] The driving mechanism 40 is arranged on the vehicle body 10, for example, the driving mechanism 40 is arranged on the first frame 101 of the vehicle body 10, and the carrying support 20 is rotatably arranged on the driving mechanism 40. As some embodiments of the present application, the number of driving mechanisms 40 is two, and the two driving mechanisms 40 are arranged on the two sides of the vehicle body 10, and the carrying support 20 is rotatably connected with the two driving mechanisms 40. The carrying support 20 can have a storage state and a working state, and the carrying support 20 can be switched between the storage state and the working state. For example, when the carrying support 20 does not need to carry components (such as photovoltaic modules), the carrying support 20 can be rotated to the storage state to reduce the space occupation of the buffer vehicle 100, so that the buffer vehicle 100 is more convenient to transfer, and when the carrying support 20 needs to carry components, the carrying support 20 can be rotated to the working state to enable the carrying support 20 to carry components.

[0038] It can be understood that when the carrying support 20 is in the working state, the angle between the carrying support 20 and the horizontal plane can be or approximately 0°, and when the carrying support 20 is in the storage state, the angle between the carrying support 20 and the horizontal plane can be but not limited to any angle between 30°-80°.

[0039] The driving mechanism 40 can drive the carrying support 20 to move along the height direction of the vehicle body 10 to adjust the carrying support 20 to an appropriate height, adapt to the height requirement of the operator, facilitate the operation of the operator, reduce the working strength of the operator, and improve the transfer efficiency.

[0040] The walking wheel 50 is arranged at the lower end of the vehicle body 10, and as some embodiments of the present application, as shown in the drawings, Figure 1 As shown, the walking wheel 50 is arranged at the lower end of the second frame 102, and the number of walking wheels 50 can be multiple, for example, the number of walking wheels 50 can be four, and the four walking wheels 50 are respectively placed at the edges of the opposite sides of the quadrilateral formed by the second frame 102. The walking wheel 50 can be constructed as a lockable universal wheel, and the movement and positioning of the buffer vehicle 100 can be realized through multiple lockable universal wheels, thereby improving the flexibility of the buffer vehicle 100.

[0041] It should be noted that the buffer vehicle 100 can be applied to photovoltaic module repair and replacement, and the buffer vehicle 100 can be used as a buffer platform of the photovoltaic module to place the photovoltaic module to be transferred. By arranging the rotatable bearing support 20, the bearing support 20 can be switched between the working state and the storage state according to actual needs, and the use is convenient. In addition, by arranging the driving mechanism 40, the height of the bearing support 20 can be adjusted to facilitate the placement or removal of the photovoltaic module, reduce the labor intensity of the workers, and improve the use convenience.

[0042] Therefore, by arranging the rotatable bearing support 20 on the driving mechanism 40, the bearing support 20 can be rotated to the storage state according to needs, the space occupation is reduced, the transfer is more convenient, the bearing support 20 can also be rotated to the working state according to needs, the use is flexible, and the driving mechanism 40 can drive the bearing support 20 to move along the height direction of the vehicle body 10 to adjust the setting height of the bearing support 20 according to actual needs, the use is more flexible, and the transfer efficiency is improved.

[0043] As some embodiments of the present application, the material of the bearing support 20 can be a high-strength lightweight material, for example, the material of the bearing support 20 can be but is not limited to aluminum alloy, aluminum-magnesium alloy, which can improve the carrying capacity of the bearing support 20 and reduce the weight of the bearing support 20.

[0044] In some embodiments of the present application, as shown in Figure 5 The expansion area of the bearing support 20 can be adjusted.

[0045] Among them, the bearing support 20 has two parts, one part is movable relative to the other part. As some embodiments of the present application, the part of the bearing support 20 is telescopic relative to the other part, so that the expansion area of the bearing support 20 is adjustable. Specifically, when the part of the bearing support 20 extends relative to the other part, the expansion area of the bearing support 20 becomes larger, and when the part of the bearing support 20 retracts relative to the other part, the expansion area of the bearing support 20 becomes smaller. As some embodiments of the present application, along the height direction of the vehicle body 10, the two parts of the bearing support 20 are stacked, and the part of the bearing support 20 is rotatable relative to the other part. Specifically, when the part of the bearing support 20 expands outward relative to the other part, the expansion area of the bearing support 20 becomes larger, and when the part of the bearing support 20 expands inward relative to the other part, the expansion area of the bearing support 20 becomes smaller.

[0046] In this way, the expansion area of the bearing support 20 can be adjusted according to the size of the component to be carried, so that the buffer vehicle 100 can be adapted to components of various sizes, and the universality and compatibility are better.

[0047] In some embodiments of the present application, as shown in Figure 1 , Figures 3-5 the carrying support 20 of the buffer trolley 100 comprises a plurality of first beams 201, the plurality of first beams 201 are sequentially connected in head-tail order, and at least one first beam 201 is configured as a telescopic rod, so that the unfolded area of the carrying support 20 can be adjusted.

[0048] Among them, as some embodiments of the present application, one carrying support 20 can include four first beams 201, and the four first beams 201 are correspondingly and parallel in pairs, and sequentially connected in head-tail order to form a quadrilateral structure. The connection mode of the adjacent two first beams 201 can be welding or bolt connection.

[0049] At least one first beam 201 is configured as a telescopic rod, which can be a buckle type telescopic rod, a pipe rotation type telescopic rod or a marble type telescopic rod. As some embodiments of the present application, one of the plurality of first beams 201 is configured as a telescopic rod.

[0050] By configuring at least one first beam 201 as a telescopic rod, the telescopic rod can be telescoped according to the size of the component to be carried, so that the telescopic rod is lengthened or shortened to adjust the unfolded area of the carrying support 20, so as to adapt to the size and shape of different components, and the operation is simple.

[0051] In some embodiments of the present application, as shown in Figure 1 , Figures 3-5 the carrying support 20 of the buffer trolley 100 comprises at least one second beam 202, and the plurality of first beams 201 surround the second beam 202, and the two ends of the second beam 202 are respectively connected with different first beams 201.

[0052] The carrying support 20 comprises one or more second beam bodies 202, which are placed in the frame formed by the first beam bodies 201, that is, the plurality of first beam bodies 201 are arranged outside the second beam bodies 202, and the two ends of the second beam bodies 202 are connected to different first beam bodies 201. As some embodiments of the present application, one carrying support 20 can comprise four first beam bodies 201, which are arranged in pairs and in parallel, and the four first beam bodies 201 are sequentially connected end to end, and the second beam body 202 can be connected between the two adjacent first beam bodies 201, or the second beam body 202 can be connected between the two corresponding first beam bodies 201. The second beam body 202 can be welded or bolted to the first beam body 201.

[0053] In the above embodiments, by arranging the second beam body 202 and surrounding the second beam body 202 with the plurality of first beam bodies 201, the structural strength of the carrying support 20 can be significantly improved, so that the carrying support 20 can carry components with relatively large weight, and the damage risk of the carrying support 20 can be reduced, and the use reliability of the carrying support 20 can be improved.

[0054] In some embodiments of the present application, as shown in Figure 6 The carrying support 20 of the buffer vehicle 100 comprises a first support body 203 and a second support body 204, the second support body 204 is stacked with the first support body 203 along the thickness direction of the carrying support 20, and the second support body 204 is movable relative to the first support body 203 along a direction perpendicular to the thickness direction of the carrying support 20.

[0055] The first support body 203 and the second support body 204 can be made of the same material, and the first support body 203 and the second support body 204 are stacked along the thickness direction of the carrying support 20, and the first support body 203 is placed above the second support body 204 or the first support body 203 is placed below the second support body 204.

[0056] As some embodiments of the present application, the second support body 204 is connected to the first support body 203 through a rotating shaft, and the second support body 204 can rotate relative to the first support body 203 about the thickness direction of the carrying support 20, so that the second support body 204 can move relative to the first support body 203 along a direction perpendicular to the thickness direction of the carrying support 20, so that the unfolding area of the carrying support 20 is adjustable.

[0057] As some embodiments of the present application, the second support body 204 is connected to the first support body 203 through a sliding rail, and the second support body 204 can slide relative to the first support body 203 along a direction perpendicular to the thickness direction of the carrying support 20, so that the unfolding area of the carrying support 20 is adjustable.

[0058] In this way, the expansion area of the carrying bracket 20 can be adjusted according to the size of the component to be carried, so that the buffer vehicle 100 can be adapted to components of various sizes, has better universality and compatibility, and is convenient to adjust the expansion area of the carrying bracket 20 and easy to operate.

[0059] In some embodiments of the present application, as shown in Figure 1 and Figure 7 The driving mechanism 40 of the buffer vehicle 100 includes a driving member 401, a transmission member 402, and a chain 403. The carrying bracket 20 is rotatably arranged on the chain 403. The transmission member 402 is engaged with the chain 403 and is in transmission connection with the driving member 401.

[0060] The driving mechanism 40 can drive the carrying bracket 20 to move along the height direction of the vehicle body 10 in the form of chain transmission. The carrying bracket 20 is arranged on the chain 403 and can rotate relative to the chain 403. The chain 403 is sleeved on the transmission member 402 and is arranged in engagement with the transmission member 402. The transmission member 402 can be configured as a driving sprocket. The driving member 401 is in transmission connection with the transmission member 402 and can drive the transmission member 402 to rotate, so as to drive the carrying bracket 20 to move along the height direction of the vehicle body 10 through the chain 403.

[0061] As some embodiments of the present application, the driving mechanism 40 further includes a driven member. The driven member can be configured as a driven sprocket 404. The chain 403 is sleeved on the driven sprocket 404 and is arranged in engagement with the driven sprocket 404. The driven sprocket 404 is arranged in interval with the driving sprocket, so as to improve the smoothness of the operation of the chain 403.

[0062] In this way, the carrying bracket 20 can be conveniently and reliably controlled to move along the height direction of the vehicle body 10. The transmission efficiency is high, the carrying capacity is strong, heavy components can be operated, the movement of the carrying bracket 20 is stable, and the use reliability of the buffer vehicle 100 is improved.

[0063] As some embodiments of the present application, the number of the driving mechanisms 40 is two. The two driving mechanisms 40 are arranged on the two sides of the vehicle body 10 respectively. The two driving mechanisms 40 each include a transmission member 402 and a driven member. The two transmission members 402 and the two driven members are connected through a transmission shaft. In this way, the chains 403 of the two driving mechanisms 40 can be operated synchronously, so as to effectively improve the stability of the movement of the carrying bracket 20.

[0065] In some embodiments of the present application, as shown in Figure 1 and Figure 7 , the driving member 401 of the buffer vehicle 100 is configured as a crank or a motor.

[0066] Among them, as shown in Figure 1 and Figure 7 , the driving member 401 is configured as a crank, the crank is in transmission connection with the transmission member 402, and the crank can be located outside the vehicle body 10. By rotating the crank, the transmission member 402 can be driven to rotate, so as to drive the bearing bracket 20 to move along the height direction of the vehicle body 10. Such arrangement can significantly reduce the manufacturing cost of the buffer vehicle 100 and improve the cost-effectiveness.

[0067] Alternatively, the driving member 401 is configured as a motor, the motor is in transmission connection with the transmission member 402, and the motor can be controlled to drive the transmission member 402 to rotate, so as to drive the bearing bracket 20 to move along the height direction of the vehicle body 10. Such arrangement can reduce the labor intensity of the workers and facilitate the control of the height of the bearing bracket 20.

[0068] In some embodiments of the present application, as shown in Figure 9 , the buffer vehicle 100 further includes a limiting member 60, the limiting member 60 is arranged on the bearing bracket 20, and the limiting member 60 is configured to abut against the vehicle body 10 when the bearing bracket 20 rotates to a preset angle, so as to limit the bearing bracket 20.

[0069] Among them, the position of the bearing bracket 20 rotating to the preset angle can be understood as the bearing bracket 20 being in the working state described above, and the limiting member 60 is fixedly arranged on the bearing bracket 20, for example, the limiting member 60 is fixedly arranged on the lower surface of the bearing bracket 20. When the bearing bracket 20 rotates to the preset angle, the limiting member 60 can abut against the vehicle body 10 to limit the rotation of the bearing bracket 20, so as to limit the bearing bracket 20 in the working state. Such arrangement can enable the bearing bracket 20 to carry parts with larger weight, and improve the use reliability of the buffer vehicle 100.

[0070] In some embodiments of the present application, as shown in Figure 8 , the bearing bracket 20 of the buffer vehicle 100 is hingedly connected or axially hole-connected with the driving mechanism 40 of the buffer vehicle 100.

[0071] The bearing bracket 20 of the buffer vehicle 100 can be connected with the chain 403 of the driving mechanism 40 through the shaft hole matching. As some embodiments of the present application, the chain 403 of the driving mechanism 40 has one of the pivot shaft or the pivot hole, and the bearing bracket 20 has the other one of the pivot shaft or the pivot hole. The pivot shaft and the pivot hole can make the bearing bracket 20 rotatable relative to the driving mechanism 40. As some embodiments of the present application, the number of the driving mechanism 40 is two, and the two driving mechanisms 40 are arranged on the two sides of the vehicle body 10. The chain 403 of the two driving mechanisms 40 has the pivot shaft, and the bearing bracket 20 has the pivot hole on the two sides of the two driving mechanisms 40. The two pivot holes are matched with the two pivot shafts to make the bearing bracket 20 rotatable relative to the driving mechanism 40. In this way, the assembly is facilitated, and the assembly difficulty of the buffer vehicle 100 is reduced. As some embodiments of the present application, the bearing bracket 20 is connected with the driving mechanism 40 through the hinge to make the bearing bracket 20 rotatable relative to the driving mechanism 40.

[0072] In this way, the bearing bracket 20 is rotatable relative to the driving mechanism 40, and the structure is simple and the rotation is reliable. The cost-effectiveness of the buffer vehicle 100 is improved.

[0073] In some embodiments of the present application, as shown in Figure 1 and Figure 7 The bearing bracket 20 of the buffer vehicle 100 is multiple, and the multiple bearing brackets 20 are arranged at intervals along the height direction of the vehicle body 10.

[0074] The number of the bearing bracket 20 can be multiple, for example, but not limited to, ten, twenty, fifty, etc. The multiple bearing brackets 20 can be arranged at intervals along the height direction of the vehicle body 10. As some embodiments of the present application, the number of the bearing bracket 20 is fifty, and the fifty bearing brackets 20 are arranged at intervals along the height direction of the vehicle body 10.
