The auxiliary assembly 3 is spaced apart from the support member 21 and is detachably connected to the base plate 1, and is used to cooperate with the support member 21 to support the battery module.

[0047] In the present device, a support member 21 is provided on the base plate 1 for supporting the battery module, a limit member 22 is detachably connected to the support member 21, a sliding member 23 is provided relative to the limit member 22, and is slidably connected to the support member 21, a clamping gap for clamping the battery module is formed between the support member 21, the limit member 22 and the sliding member 23, the sliding member 23 slides close to or away from the limit member 22, and can clamp or release the battery module, the auxiliary component 3 is spaced apart from the support member 21, and is used to cooperate with the support member 21 to form support for the battery module.

[0048] Compared with the prior art, the present device sets a detachable structure between the limit member 22 and the support member 21. When the operation at the workstation is completed and the battery module needs to be removed, the limit member 22 can be removed from the support member 21, so that the user can take out the battery module by only translating the battery module, avoiding the need to lift the battery module first and then translate it. The operation is simple and convenient, and can solve the technical problem in the prior art that the reference component is fixed on the carrier, so when the battery module is removed from the carrier, the battery module must be lifted first and then translated to take it out, resulting in inconvenient operation.

[0049] Furthermore, the bottom plate 1 in the present device is a common and easily purchased tray on the market, which is a flat structure. Here, the bottom plate 1 is connected to the work station to support and connect the battery module. This is a conventional setting known to technicians in this field and will not be elaborated on.

[0050] like Figures 1 to 3 As shown, the support member 21 includes two first support blocks 211 and two second support blocks 212. The two first support blocks 211 are parallel to each other and spaced apart, and are both connected to the base plate 1. The two second support blocks 212 are spaced apart from each other and are respectively arranged at both ends of the two second support blocks 212, and the two second support blocks 212 are respectively connected to the two first support blocks 211.

[0051] The two first support blocks 211 and the two second support blocks 212 are arranged perpendicular to each other to form a support structure with a hollow center, which is used to support and connect the sliding member 23 and the limiting member 22 .

[0053] The two first support blocks 211 have sliding grooves on opposite sides thereof. Both ends of the sliding block 231 are slidably embedded in the sliding grooves. The clamping block 232 is disposed opposite to the limiting member 22 and connected to the sliding block 231 .

[0054] The cooperation between the sliding block 231 and the sliding groove plays a connecting and guiding role in the sliding of the clamping block 232 relative to the limiting member 22 .

[0056] The connection between the rolling portion 233, the sliding block 231 and the sliding groove is used to reduce the friction when the sliding block 231 slides relative to the sliding groove, thereby improving the stability of the device operation.

[0057] Furthermore, the rolling part 233 here is a steel ball or steel ball which is common and easy to purchase in the market, and will not be described in detail here.

[0058] As another implementation method, Figures 1 to 3 As shown, the sliding block 231 is provided with a first threaded hole, and the first threaded hole passes through the sliding block 231. The two second support blocks 212 are provided with rotating holes respectively relative to the threaded holes. The rotating bearings 234 are respectively embedded in the rotating holes. One end of the screw rod 235 is rotatably inserted in the bearing hole of a rotating bearing 234, and the other end is threadedly connected to the first threaded hole and inserted in the bearing hole of another rotating bearing 234.

[0059] The rotating bearing 234 serves to connect the relative rotation between the screw rod 235 and the two second supporting blocks 212 .

[0060] Furthermore, in the device, the screw 235 is threadedly matched with the first threaded hole of the sliding block 231, forming a driving structure similar to a ball screw nut pair. The rotation of the screw 235 around its axis can drive the sliding block 231 to slide along the guide of the slide groove.

[0061] Furthermore, the screw rod 235 can be driven to rotate relative to the second support block 212 manually, or driven to rotate relative to the second support block 212 by the output shaft of the motor, which will not be described in detail here.

[0062] like Figure 2 , Figure 3 As shown, a second support block 212 is provided with two slots, and the limiting member 22 includes a limiting block 221, two slide rods 222 and at least two clamping portions 223. The slide rods 222 are arranged in a one-to-one correspondence with the slots. One ends of the two slide rods 222 are respectively slidably inserted in the two slots, and the other ends are connected to the limiting block 221. The clamping portion 223 is connected to the second support block 212 and can be clamped with the slide rod 222 to limit the slide rod 222 from sliding relative to the slot.

[0063] The slide bar 222 is detachably connected to the second support block 212 via the clamping portion 223 , and the limit block 221 is detachably connected to the second support block 212 via the connection slide bar 222 .

[0064] As an implementation method, Figure 2 , Figure 4 and Figure 5 As shown, the second support block 212 is provided with a plurality of connecting holes, which are connected with the slots, the slide rod 222 is provided with a second threaded hole relative to the connecting holes, the clamping portion 223 has a large diameter section and a threaded section, the clamping portion 223 is arranged in one-to-one correspondence with the connecting holes, the threaded section of the clamping portion 223 passes through the connecting hole and is threadedly connected to the second threaded hole, and the large diameter section of the clamping portion 223 abuts against the outer wall of the second support block 212.

[0066] Furthermore, the clamping portion 223 here can also be an elastic clamping block. When the slide rod 222 is inserted into the slot and the connecting hole is aligned with the second threaded hole, the elastic clamping block can automatically clamp into the connecting hole and the second threaded hole, and limit the slide rod 222 from sliding relative to the slot. At the same time, the elastic clamping block can also be easily pulled out, and the elastic clamping block can slide away from the elastic clamping block to release the clamping connection between the elastic clamping block and the connecting hole and the second threaded hole. No further details will be given here.

[0067] like Figures 1 to 3 As shown, the base plate 1 is provided with a plurality of third threaded holes, the auxiliary component 3 includes two third support blocks 31 and a plurality of fastening connection parts, the two third support blocks 31 are respectively arranged on both sides of the two first support blocks 211, and the plane where the top of the third support block 31 is located is coplanar with the plane where the top of the first support block 211 is located, the third support block 31 is provided with a fixing hole relative to the third threaded hole, and the threaded section of the fastening connection part passes through the fixing hole and is threadedly connected to the third threaded hole.

[0068] The two third support blocks 31 are spaced apart and detachably connected to the two sides of the two first support blocks 211 , and the plane where the top of the third support block 31 is located is coplanar with the plane where the top of the first support block 211 is located, so as to be suitable for battery modules of different widths.

[0069] As an implementation method, Figures 1 to 3 As shown, the third support block 31 is provided with at least one weight-reducing hole 32 .

[0070] At least one weight-reducing hole 32 is disposed on the third support block 31 to reduce the weight of the third support block 31 and facilitate the transfer, installation and disassembly of the device.

[0071] As another implementation method, Figures 1 to 3 As shown, the device further comprises four handles 4 , which are evenly distributed around the bottom plate 1 and hinged to the bottom plate 1 .

[0072] The four handles 4 are respectively hinged to the bottom plate 1 , so that the user can lift the bottom plate 1 as a whole conveniently. The four handles 4 are evenly distributed around the bottom plate 1 and hinged to the bottom plate 1 .

[0073] Furthermore, the handle 4 here is a hinged structure that is common and easy to purchase on the market, and is a conventional setting well known to those skilled in the art, and will not be described in detail here.

[0074] In the specific working process of the utility model, a support member 21 is arranged on the bottom plate 1 for supporting the battery module, a limit member 22 is detachably connected to the support member 21, a sliding member 23 is arranged relative to the limit member 22, and is slidably connected to the support member 21, a clamping gap for clamping the battery module is formed between the support member 21, the limit member 22 and the sliding member 23, the sliding member 23 slides close to or away from the limit member 22, and can clamp or release the battery module, the auxiliary component 3 is arranged at intervals with the support member 21, and is used to cooperate with the support member 21 to form a support for the battery module. Compared with the prior art, the present device sets a detachable structure between the limit member 22 and the support member 21. When the operation at the workstation is completed and the battery module needs to be removed, the limit member 22 can be removed from the support member 21, so that the user can take it out by only translating the battery module, avoiding lifting the battery module first and then translating it, and the operation is simple and convenient.

[0075] When in use, the user first drives the clamping block 232 to slide away from the limit block 221 and adjusts the clamping gap to increase, and then places the battery module into the clamping gap, where the bottom plane of the battery module respectively abuts against the top planes of the first support block 211 and the third support block 31, and then rotates the screw 235 to make the sliding block 231 and the clamping block 232 slide close to the limit block 221, and clamp the battery module, and finally the relevant production operations can be carried out.

[0076] Furthermore, when the battery module needs to be removed from the device after completing the production operation, the user only needs to remove the clamping part 223 from the third threaded hole and pull the sliding rod 222 out of the slot. Here, the limit block 221 can be easily separated from the second support block 212. Finally, the user slides the battery module along the plane where the top of the first support block 211 is located to remove it from the clamping gap. There is no need to lift the battery module and then translate it, which is convenient for operation.

[0077] The device, through the above structure, can solve the technical problem in the prior art that because the reference assembly is fixed on the carrier, the battery module must be lifted first and then moved horizontally to be removed from the carrier, resulting in inconvenient operation.

[0078] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
