Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a vehicle that integrates battery pack production, assembly, and turnover. Background Technology

[0002] As the energy demands of energy storage and power battery packs increase, the weight of these packs is also growing, with large, heavy-duty packs even exceeding one ton. Currently, the production, assembly, and transportation of battery packs primarily rely on production lines and transport equipment such as cranes and flatbed trolleys. In other words, battery packs must first be assembled on the production line, and then transported to other locations using cranes, flatbed trolleys, and other transportation equipment.

[0003] However, both production lines and equipment such as cranes and flatbed trolleys have their drawbacks. For example, production lines (production workshops) usually require fixed installation, occupy a large area, have high costs, and lack flexibility. Battery packs assembled on the production line still need to be transferred to debugging or testing stations using cranes, flatbed trolleys, and other transportation equipment, which takes a long time. In addition, there is a risk of damaging the battery packs during the process of moving them from the production line to the transportation equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a battery pack production, assembly and turnover integrated vehicle.

[0005] The objective of this utility model is achieved through the following technical solution:

The moving wheel assembly is installed at the bottom of the load-bearing limiting frame. The assembly positioning block is installed in the mounting hole and has an assembly positioning hole.

[0007] In one embodiment, the assembly positioning hole is a stepped positioning hole structure.

[0008] In one embodiment, multiple mounting holes are provided, and the center lines of each mounting hole form a triangular or quadrilateral distribution structure; and multiple assembly positioning blocks are provided, with each assembly positioning block correspondingly installed in each mounting hole.

[0010] In one embodiment, the limiting cavity further includes a first limiting sidewall and a second limiting sidewall, the first limiting sidewall and the second limiting sidewall being disposed opposite to each other, and the assembly positioning sidewall being located between the first limiting sidewall and the second limiting sidewall, and the height of the assembly positioning sidewall being higher than the first limiting sidewall and the second limiting sidewall.

[0022] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0023] Please see Figure 1 and Figure 2 As shown, a battery pack production assembly and turnover integrated vehicle 10 includes: a load-bearing limiting frame 100, a moving wheel assembly 200, and an assembly positioning block 300. The load-bearing limiting frame 100 is provided with a limiting cavity, and at least one side wall of the limiting cavity is an assembly positioning side wall 110, on which an assembly positioning side wall 110 is provided with an assembly hole. The moving wheel assembly 200 is installed at the bottom of the load-bearing limiting frame 100. The assembly positioning block 300 is installed in the mounting hole, and an assembly positioning hole 310 is provided on the assembly positioning block 300.

[0024] It should be noted that during the production and assembly of the battery pack, the positioning pins on the battery pack casing are first inserted into the assembly positioning holes 310 of the assembly positioning block 300 to fix the battery pack. At this time, part of the battery pack casing is housed within the limiting cavity, and part is located outside the limiting cavity. Then, other components can be assembled. After the battery pack production and assembly are completed, when it needs to be moved to a charging / discharging cabinet, or moved outdoors for testing or debugging, the moving wheel assembly 200 at the bottom of the supporting limiting frame 100 can be used to move the battery pack. This integrates the battery pack production and assembly functions with the moving function, reducing equipment changeover time, lowering the risk of battery pack damage, thereby reducing costs and improving production efficiency. In this embodiment, the moving wheel assembly 200 includes six moving wheels, and the moving wheels can be omnidirectional wheels.

[0025] Please see Figure 2As shown, in one embodiment, the assembly positioning hole 310 is a stepped positioning hole structure. That is, the assembly positioning hole 310 is a stepped positioning hole structure composed of a combination of large holes and small holes. The stepped structure can improve positioning accuracy while ensuring structural strength. Among them, the transition section between the large-diameter section and the small-diameter section is a beveled chamfer structure, which can guide the positioning post on the battery pack casing to be quickly inserted into the assembly positioning hole, thereby improving assembly efficiency.

[0026] It should also be noted that the mounting hole is a through hole structure that penetrates the assembly positioning sidewall 110. The shape of the mounting hole matches the shape of the assembly positioning block 300. When it is necessary to install and fix the battery pack casing, first insert the positioning post of the battery pack casing into the assembly positioning hole 310, and then use a nut to lock and fix it.

[0027] In one embodiment, the assembly positioning block 300 is detachably connected to the assembly positioning sidewall 110 via a screw connection. This facilitates the replacement of worn assembly positioning blocks 300 without requiring the complete disassembly of the load-bearing limit frame, thus reducing maintenance costs. It also allows for the replacement of assembly positioning blocks 300 of different sizes, enabling adaptation to the assembly of different battery pack housings. For example, the screw connection can be a screw or bolt.

[0028] Please see Figure 1 As shown, in one embodiment, multiple mounting holes are provided, and the center lines connecting the mounting holes form a triangular or quadrilateral distribution structure. Multiple assembly positioning blocks 300 are also provided, each corresponding to a mounting hole. When there are three mounting holes, the center lines connecting them form a triangular distribution structure; when there are four mounting holes, the center lines forming a quadrilateral distribution structure. Using a triangular or quadrilateral distribution structure further improves positioning accuracy while ensuring the stability of the battery pack, reducing the risk of significant positional shifts during battery pack movement, thereby reducing vibration and protecting the precision components inside the battery pack.

[0029] Please see Figure 1As shown, in one embodiment, the limiting cavity further includes a first limiting sidewall 320 and a second limiting sidewall 330, which are arranged opposite to each other. The assembly positioning sidewall 110 is located between the first limiting sidewall 320 and the second limiting sidewall 330, and the height of the assembly positioning sidewall 110 is higher than that of the first limiting sidewall 320 and the second limiting sidewall 330. The limiting cavity formed by the first limiting sidewall 320, the second limiting sidewall 330, and the assembly positioning sidewall 110 enables the battery pack to be positioned. At the same time, the height of the assembly positioning sidewall 110 is higher than that of the first limiting sidewall 320 and the second limiting sidewall 330. The higher sidewall of the assembly positioning sidewall 110 provides a larger positioning area for positioning the battery pack casing and can also limit the positional displacement of the battery pack to a greater extent. The lower sidewalls of the first limiting sidewall 320 and the second limiting sidewall 330 make it easier for operators to assemble the battery pack and to access it.

[0030] Please see Figure 1 and Figure 3 As shown, the battery pack casing placed inside the limiting cavity is not completely flush with the side wall of the limiting cavity. Therefore, the battery pack is prone to shaking during its turnover. Therefore, the battery pack production assembly and turnover integrated vehicle 10 also includes a limiting component 400. The limiting component 400 includes a first limiting member 410 and a second limiting member 420. The first limiting member 410 is disposed on the first limiting side wall 320, and the second limiting member 420 is disposed on the second limiting side wall 330. The first limiting member 410 and the second limiting member 420 are respectively used to abut and limit the battery pack against the side wall. In this way, the battery pack can be prevented from shaking during turnover, avoiding collision damage.

[0031] Furthermore, the first limiting member 410 includes a plurality of first limiting blocks 411, each of which is respectively installed on the top of the first limiting sidewall 320. The first limiting blocks 411 are detachable, allowing them to be disassembled and replaced to accommodate battery packs of different sizes. For example, the first limiting blocks 411 can be connected and fixed to the first limiting sidewall 320 using bolts or screws. Specifically, the first limiting block 411 includes a mounting portion 411a and a supporting limiting portion 411b. The mounting portion 411a is detachably installed on the top of the first limiting sidewall 320. One end of the supporting limiting portion 411b is connected to the mounting portion 411a, and the other end of the supporting limiting portion 411b extends towards the limiting cavity, giving the first limiting block 411 a "Z"-shaped structure. In this embodiment, the first limiting block 411 is an elastic scratch-resistant limiting block. By using an elastic scratch-resistant material, it can provide buffer protection for the battery pack, that is, absorb vibration energy through the elastic material to prevent scratches on the surface of the battery pack. For example, the elastic scratch-resistant material can be wear-resistant rubber or polyurethane, etc.

[0032] Please see Figure 1 As shown, in one embodiment, a mounting protrusion 321 is provided on the first limiting sidewall 320. The free end of the mounting protrusion 321 extends away from the limiting cavity, and the mounting portion 411a of the first limiting block 411 is mounted on the mounting protrusion 321. By increasing the mounting protrusion 321, sufficient mounting area can be provided for the first limiting block 411, ensuring the installation stability of the first limiting block 411. At the same time, the local strength of the first limiting sidewall 320 can be improved, avoiding long-term deformation under pressure. It should also be noted that the structure of the first limiting member 410 is the same as the structure of the second limiting member 420. Correspondingly, the structure of the first limiting sidewall 320 is the same as the structure of the second limiting sidewall 330.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
