Detailed Implementation

[0039] This utility model discloses a tray for battery packs, which solves the technical problem that existing trays for battery packs cannot be compatible with battery packs of different sizes and specifications.

[0040] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 6The present invention provides a tray for a battery pack, comprising a first support frame 1, a second support frame 2, and a plurality of connecting beams 3. The first support frame 1 and the second support frame 2 extend along the X-axis, and the first support frame 1 and the second support frame 2 are spaced apart along the Y-axis. The plurality of connecting beams 3 extend along the Y-axis and are detachably connected between the first support frame 1 and the second support frame 2.

[0042] This utility model relates to a tray for battery packs, specifically comprising a first support frame 1, a second support frame 2, and multiple connecting beams 3. Both the first support frame 1 and the second support frame 2 extend along the X-axis, and are spaced apart along the Y-axis. The multiple connecting beams 3 extend along the Y-axis and are detachably connected between the first support frame 1 and the second support frame 2. Through this design, since the connecting beams 3 can be detachably connected to the first support frame 1 and the second support frame 2, the tray of this utility model can be adjusted according to the size specifications of the battery pack by directly replacing the longitudinal beams of different sizes. This allows the tray to be compatible with battery packs of different sizes, reducing production costs and improving production efficiency.

[0043] Furthermore, in this embodiment, the connecting beam 3 is a connecting beam with telescopic function.

[0044] It should be noted that the above design allows for easy adjustment of the tray's length in the Y-axis direction, enabling the tray to accommodate battery packs of different sizes without frequent tooling changes. The telescopic connecting beam also reduces the requirements for manufacturing precision, decreases assembly difficulty and cost, and can compensate for dimensional tolerances or thermal deformation of the battery pack during manufacturing, ensuring assembly accuracy.

[0045] In addition, the connecting beam 3 with telescopic function is a telescopic rod commonly used in the prior art, which should be easily understood by those skilled in the art. Therefore, its specific structure will not be described in this embodiment.

[0046] Furthermore, in this embodiment, the connecting beam 3 has a first end and a second end that are disposed opposite to each other;

[0047] Wherein, a first mounting hole 301 is provided on the first end, a second mounting hole 302 is provided on the second end, and a first threaded hole is provided on the first support frame 1 at the position corresponding to the first end;

[0048] A first screw is inserted into the first mounting hole 301. The threaded end of the first screw passes through the first mounting hole 301 and is threaded into the first threaded hole so that the first end is fixed to the first support frame 1.

[0049] The second support frame 2 has a second threaded hole at the position corresponding to the second end;

[0050] A second screw is inserted into the second mounting hole 302. The threaded end of the second screw passes through the second mounting hole 302 and is threaded into the second threaded hole so that the second end is fixed to the second support frame 2. The bolt connection not only allows the pallet to replace only the damaged parts, reducing maintenance costs and extending the service life of the pallet, but also the removable bolts improve the efficiency of troubleshooting pallet faults.

[0051] It should be noted that, through the above design, the two ends of the connecting beam 3 in this embodiment are respectively fixed to the first support frame 1 and the second support frame 2 by screws. This method makes it easier for operators to disassemble and assemble the connecting beam 3 in order to adjust the size and specifications of the tray, so that the tray can adapt to battery packs of different sizes and specifications. At the same time, it is conducive to adapting to future technology iteration needs without redesigning the entire tray.

[0052] Furthermore, in this embodiment, the first support frame 1 is provided with a first mounting surface 101, and the second support frame 2 is provided with a second mounting surface 201;

[0053] Both the first mounting surface 101 and the second mounting surface 201 can be detachably mounted with a plurality of limiting blocks 4 arranged sequentially along the X-axis direction;

[0054] The limiting block 4 on the first mounting surface 101 and the limiting block 4 on the second mounting surface 201 are configured one-to-one to limit the battery pack.

[0055] It should be noted that the design of the aforementioned limiting block 4 can limit the battery pack placed on the tray, preventing the battery pack from shifting.

[0056] Specifically, in this embodiment, the limiting block 4 includes a first limiting block 4a and a second limiting block 4b;

[0057] Among them, on the first mounting surface 101 and the second mounting surface 201, two first limiting blocks 4a are set at a preset distance along the X-axis direction, and a plurality of second limiting blocks 4b are arranged sequentially at intervals along the X-axis direction within the preset distance;

[0058] The first limiting block 4a includes a first limiting part 401 for limiting the movement of the battery pack along the Y-axis direction and a second limiting part 402 for limiting the movement of the battery pack along the X-axis direction;

[0059] The second limiting block 4b includes a first limiting part 401 for limiting the movement of the battery pack along the Y-axis direction.

[0060] It should be noted that in this embodiment, the first limiting block 4a is mainly set to correspond to the corners of the battery pack. The first limiting part 401 and the second limiting part 402 on the first limiting block 4a abut against the width side and the length side of the battery pack, respectively, thereby effectively limiting the displacement of the battery pack on the tray along the X-axis and Y-axis directions, that is, effectively limiting the displacement of the battery pack in the horizontal direction.

[0061] In addition, the second limiting block 4b is mainly set to correspond to the length side of the battery pack. The first limiting part 401 on the second limiting block 4b abuts against the length side of the battery pack, thereby effectively limiting the displacement of the battery pack on the tray along the Y-axis.

[0062] Furthermore, to prevent the first limiting block 4a and the second limiting block 4b from damaging the battery pack when performing the limiting function, in this embodiment, the first limiting block 4a and the second limiting block 4b are both made of rubber, silicone or other materials with a certain elasticity.

[0063] Furthermore, in this embodiment, a plurality of third threaded holes 6 are provided on the first mounting surface 101 and the second mounting surface 201;

[0064] The limiting block 4 has multiple third mounting holes, and a third screw is inserted into the third mounting hole. The threaded end of the third screw passes through the third mounting hole and is threaded to the third threaded hole 6 so that the limiting block 4 is fixed to the first mounting surface 101 and the second mounting surface 201.

[0065] It should be noted that, through the above design, the limiting block 4 can be detachably installed on the first mounting surface 101 and the second mounting surface 201, so that the operator can adjust the installation position of the limiting block 4 according to the specific size and specifications of the battery pack. The detachable installation method also facilitates cleaning of dust or residue inside the limiting block 4, ensuring the cleanliness of the battery pack assembly.

[0066] Furthermore, in this embodiment, both the first mounting surface 101 and the second mounting surface 201 can be detachably mounted with limiting components 5 for restricting the movement of the battery pack in the Z-axis direction, wherein the limiting components 5 on the first mounting surface 101 and the limiting components 5 on the second mounting surface 201 are configured in a one-to-one correspondence.

[0067] It should be noted that the design of the aforementioned limiting component 5 can restrict the movement of the battery pack on the tray along the Z-axis.

[0068] Specifically, the limiting component 5 includes a base 501, a pressure plate 504, a rotating shaft 503, a shaft seat 502, a bracket 505, and a locking pin 506;

[0069] The base 501 is detachably mounted on the first mounting surface 101 and the second mounting surface 201. The bearing seat 502 is mounted on the base 501. The rotating shaft 503 is rotatably connected to the bearing seat 502 and connected to the pressure plate 504. The pressure plate 504 can be driven to rotate relative to the bearing seat 502 to press against the battery pack from the Z-axis direction, which facilitates the alignment and fit with the battery pack. The end of the rotating shaft 503 away from the pressure plate 504 is provided with a locking groove 5031.

[0070] The bracket 505 is mounted on the base 501, and the locking pin 506 is slidably connected to the bracket 505;

[0071] When the pressure plate 504 is in the pressed state, the locking pin 506 is driven to move toward the end of the rotating shaft 503 away from the pressure plate 504 to insert into the locking groove 5031 to restrict the rotation of the pressure plate 504. The restriction can be quickly released by pulling out the locking pin 506 and rotating the pressure plate 504, and the battery pack can be unloaded from the tray without complicated tools, which is convenient for replacement and reduces costs.

[0072] It should be noted that the specific working principle of the aforementioned limit component 5 is as follows:

[0073] After the pressure plate 504 rotates relative to the bearing 502 via the rotating shaft 503, it presses against the top surface of the battery pack. Meanwhile, the locking pin 506 moves relative to the bracket 505 and is inserted into the locking groove 5031 of the rotating shaft 503, thereby restricting the rotation of the rotating shaft 503 and thus making the pressure plate 504 continuously press against the top surface of the battery pack.

[0074] The above design allows the top surface of the battery pack to be continuously restricted, preventing displacement of the battery pack in the Z-axis direction and ensuring its stability during vibration or collision during production line transportation.

[0075] Furthermore, to prevent the pressure plate 504 from damaging the surface of the battery pack during the pressing process, it is preferable that the entire pressure plate 504 or the contact position between the pressure plate 504 and the battery pack is covered with a rubber pad 508.

[0076] Furthermore, to facilitate the movement of the locking pin 506 by the operator, an operating handle 507 is also provided at the end of the locking pin 506 in this embodiment.

[0077] Furthermore, in this embodiment, the base 501 is provided with a fourth mounting hole 509, which is correspondingly provided with the third threaded hole 6. A fourth screw is inserted into the fourth mounting hole 509, and the threaded end of the fourth screw passes through the fourth mounting hole 509 and is threadedly connected to the third threaded hole 6 so that the base 501 can be detachably fixed to the first mounting surface 101 and the second mounting surface 201.

[0078] It should be noted that, through the above design, the limiting component 5 can be detachably installed on the first mounting surface 101 and the second mounting surface 201, thereby enabling operators to adjust the installation position of the limiting component 5 according to the specific size specifications of the battery pack, or to replace the limiting component 5 with one suitable for battery packs of different thicknesses. This modular installation method significantly improves the flexibility of the battery pack production line and provides hardware support for diversified market demands.

[0079] The above provides a detailed description of a tray for a battery pack provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
