[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] like Figure 1-4As shown, a pallet structure of a lithium battery module includes a battery module clamping mechanism 1 for clamping the lithium battery module, and also includes a position adjustment mechanism 2 installed on a bottom plate, the battery module clamping mechanism is installed on the position adjustment mechanism, the position adjustment mechanism is used to adjust the clamping width of the battery module clamping mechanism, and the two sides of the position adjustment mechanism are provided with a positioning mechanism 3 for positioning the position adjustment mechanism. In this device, the position adjustment mechanism can be two plates with adjustable spacing, the battery module clamping mechanism is placed on the plates, and the clamping width of the battery module clamping mechanism is controlled by adjusting the distance between the two plates, and the battery module clamping mechanism can be an existing structure in the background technology, that is, the cylinder drives the clamping plate to move toward the fixed plate, and the clamping work of the battery module is realized by the clamping plate and the fixed plate. In addition, the positioning mechanism can be a bolt, a quick clamp, etc. that can realize a quick fixing component. The device can adjust the clamping width of the battery module clamping mechanism through the position adjustment mechanism, so as to adapt to battery modules of different widths. This design improves the compatibility of the pallet, so that a pallet can meet the transportation needs of multiple battery cells.

[0024] Specifically, in this preferred embodiment, Figure 1 and Figure 2 As shown, the position adjustment mechanism 2 includes a left sliding mounting plate 21, a right sliding mounting plate 22 and a sliding guide rail 23. A plurality of the sliding guide rails are fixed side by side on the bottom plate. The left sliding mounting plate and the right sliding mounting plate are correspondingly arranged, and the bottoms of the two slide with the sliding guide rails respectively. The left sliding mounting plate 21 and the right sliding mounting plate 22 have the same structure. The length directions of the two are respectively perpendicular to the sliding guide rails, and the distance between the two can be adjusted. By controlling the distance between the left sliding mounting plate and the right sliding mounting plate, battery modules of different widths can be used, and the transportation requirements of various battery cells can be met, reducing the cost of enterprises purchasing various pallets of different sizes, which helps to improve production efficiency and reduce production costs.

[0025] Furthermore, in order to be able to lock the above-mentioned position adjustment mechanism, as Figure 1As shown, the positioning mechanism 3 includes a limit tooth plate 31 and a positioning tooth 32. There are four limit tooth plates in total, which are distributed on both sides of the bottom plate. Corresponding to them are four positioning teeth, each of which is meshed with the corresponding limit tooth plate. In order to facilitate the control of the movement of the positioning tooth 32, the positioning tooth 32 can be installed on the elbow clamp to quickly achieve the meshing of the positioning tooth and the limit tooth plate. The positioning of the position adjustment mechanism is achieved by the mutual meshing between the positioning tooth and the limit tooth plate. When the width of the position adjustment mechanism is determined, the positioning mechanism is locked and positioned to prevent the position adjustment mechanism from moving and affecting the clamping work of the battery module. In order to quickly adjust the position adjustment mechanism, a ruler is provided on the upper part of the limit tooth plate. When the width of the battery module is known, the distance between the left sliding mounting plate and the right sliding mounting plate can be accurately controlled by the ruler, which reduces the adjustment time and improves the production efficiency.

The positioning of the position adjustment mechanism is achieved by inserting the positioning pin into the positioning hole on the positioning plate. Compared with the first positioning mechanism, this positioning mechanism is similar to the structure of a latch, and the positioning pin needs to be inserted into the positioning hole to achieve positioning.

[0027] In this embodiment, the battery module clamping mechanism 1 includes a cylinder 11, a movable splint 12 and a fixed splint 13. The movable splint is fixed on the piston rod of the cylinder. The cylinder is fixed on the left sliding mounting plate or the right sliding mounting plate. In this embodiment, the installation of the right sliding mounting plate is taken as an example for description. The bottom of the cylinder is fixed to the right sliding mounting plate through a first fixed block 14; the fixed splint is fixed to the left sliding mounting plate through a second fixed block 15. The first fixed block is set in an inverted T shape, and the second fixed block is set in an L shape. The fixed splint is fixed on the right sliding mounting plate or the left sliding mounting plate and corresponds to the movable splint. In this embodiment, the fixed splint is fixed on the left sliding mounting plate as an example for description. Both the movable splint and the fixed splint are made of rubber material. The movable splint is driven to move by the cylinder, and the movable splint cooperates with the fixed splint to clamp the battery module.

[0028] In order to facilitate the support of the battery module, the inner edges of the left sliding mounting plate and the right sliding mounting plate are respectively fixed with insulating pads 24, and the insulating pads are slidably connected with limit stops 25, which are used to position the length direction of the battery module. The battery module is placed on the insulating pad, and the movable clamp is driven by the cylinder to cooperate with the fixed clamp to fix the corresponding battery module. The insulating pad is used to support the battery module, has excellent insulation performance, provides insulation support for the battery module, reduces the risk of leakage, and ensures the normal operation of the battery module.

[0029] Furthermore, in order to realize the electrical performance test of the battery module, a test adapter block 4 is fixed on both sides of the bottom plate, and the limit block is connected to the detection contact point 41 on the test adapter block through a wire. A plurality of detection contact points are provided on the surface of the test adapter block. Through the connection of the external device with the detection contact point, the resistance, insulation resistance and other parameters of the battery module components are monitored in real time to ensure the stability and safety of the battery module during assembly.

[0030] For the convenience of adjusting the left and right sliding mounting plates, the left sliding mounting plate and the right sliding mounting plate are respectively fixed with handrails 26. Holding the handrails can quickly make the left and right sliding mounting plates slide to both sides on the sliding guide rail, and then quickly adjust the spacing.

[0031] Working principle: When in use, hold the armrest, and adjust the spacing between the left and right sliding mounting plates by sliding to both sides on the sliding guide rails. Push the positioning teeth in the positioning mechanism to clamp the limiting tooth plate for limiting. Then, place the battery module on the insulating pad, and use the cylinder to drive the movable splint to cooperate with the fixed splint to fix the battery module in the width direction. The limit block limits the length direction of the battery module. The detection contact point is connected to the heating film terminal of the battery module through wires. The external device probe contacts the external metal sheet of the detection contact point to perform electrical testing on the heating film on the battery module.
