[0034] The end of the limiting part 1121 away from the bottom of the layer plate 1 is provided with a guiding inclined surface 11211, and the guiding inclined surfaces 11211 of the two limiting parts 1121 form an inverted eight-shaped structure, and the guiding inclined surfaces 11211 facilitate the insertion of the battery into the limiting space formed by the limiting part 1121. The edges of the guiding inclined surfaces 11211 are provided with rounded corners to prevent the sharp parts of the guiding inclined surfaces 11211 from scratching the battery when the battery is inserted. In another embodiment, a protective pad can also be provided at the edge of the guiding inclined surface 11211 to avoid scratching the battery.

[0035] A second boss 15 extends from both ends of the layer plate 1, and the slide groove 12 is opened downwardly and is arranged on the second boss 15. It is convenient to adjust the position of the layer plate 1 assembled on the guide rod of the battery restraint tray, and it is easy to disassemble. Specifically, the cross-section of the slide groove 12 is a semicircular cross-section, which matches the outer diameter of the guide rod of the battery restraint tray. The number of the slide grooves 12 is 4, which are respectively arranged at the top and bottom of both ends of the layer plate 1 to enhance the stability of the layer plate 1 moving on the guide rod. In other embodiments, the number of the slide grooves 12 can also be 6, 8 or other numbers.

[0036] Please also read Figure 7 The layer plate 1 has two clamping planes 11 arranged opposite to each other, and the layer plates 1 adjacent to each other can cooperate to clamp the battery. Multiple layer plates can cooperate with each other to clamp the battery in batches, thereby reducing costs and increasing efficiency.

[0037] The clamping plane 11 is also provided with a connection block 113 for linkage with other layer plates 1, the connection block 113 is perpendicular to the bottom of the layer plate 1, and the connection block 113 includes a first hook 1131 and a second hook 1132, the first hook 1131 is perpendicularly arranged on the clamping plane 11, and the second hook 1132 extends from one end of the first hook 1131 away from the clamping plane 11 and is parallel to the clamping plane 11. The outer diameter of the first hook 1131 gradually increases in the direction close to the clamping plane 11, thereby increasing the strength of the first hook 1131 and providing a higher tensile strength. The linkage process of the layer plate 1 is as follows: the layer plate 1 includes a first layer plate and a second layer plate, and the first layer plate and the second layer plate are slidably fixed on the guide rod of the battery restraint tray through the slide groove 12 in advance, and then the second layer plate is lifted, and the second layer plate is moved to the top of the first layer plate along the length direction of the guide rod, and its second hook 1132 is aligned with the second hook 1132 of the first layer plate and clamped, and then slid and fixed on the guide rod, at this time, the first layer plate and the second layer plate can slide relative to each other on the guide rod, and the relative sliding distance between the two is the distance between the second hook 1132 of the second layer plate and the clamping plane of the first layer plate. In another embodiment, the length of the first hook 1131 can be telescopically adjusted, and the corresponding length is adjusted according to the thickness of the battery.

[0038] The deformable plate 2 is made of a plastic material with elastic deformation, and can be elastically deformed to fit tightly against the battery, so that the force on the battery is balanced and the restraint effect is improved. In addition, the plastic material is insulated from the battery, further reducing safety hazards.

[0039] Please also read Figure 8The fixing column 21 includes a sleeve portion 211, a guide portion 212 and a pulling portion 213 which are coaxially arranged in sequence. The sleeve portion 211 is vertically fixed to the deformable plate 2. The guide portion 212 is a conical structure, and its maximum outer diameter is greater than the inner diameter of the fixing hole 111. The pulling portion 213 and the guide portion 212 pass through the fixing hole 111 in sequence. The sleeve portion 211 is inserted into the fixing hole 111, and the guide portion 212 is engaged with the fixing hole 111. In this embodiment, the fixing column 21 is integrally formed with the deformable plate 2, so the fixing column 21 also has the performance of elastic deformation. The assembly process of the fixing column 21 and the fixing hole 111 is as follows: first align the fixing column 21 with the fixing hole 111 and insert it, at which time the pulling portion 213 passes through the fixing hole 111, and then use a clamping tool such as a clamp to clamp and forcefully pull the pulling portion 213, the guide portion 212 is interference-fitted with the fixing hole 111 under the action of external force, and finally passes through the fixing hole 111, at which time the limiting portion 1121 is sleeved on the fixing hole 111. Since the maximum outer diameter of the guide portion 212 is greater than the inner diameter of the fixing hole 111, and since the guide portion 212 is a conical structure, the fixing column 21 cannot be detached from the fixing hole 111 without using brute force. In another embodiment, the fixing column 21 is assembled with the deformable plate 2 as a whole, the fixing column 21 is a threaded column, and the fixing column 21 is locked by a nut after passing through the fixing hole 111.

[0040] The protective film 3 is made of plastic material, specifically, the protective film 3 is made of polypropylene material. Polypropylene material is insulated from the battery, which can further reduce safety hazards. In addition, polypropylene material has good resistance to most acids, alkalis and organic solvents and is not easily corroded. Therefore, for corrosive electrolytes, polypropylene material can well protect the deformable plate 2. In addition, polypropylene material has a high melting point and can maintain good performance at high temperatures, which is suitable for the working environment of this application. In other embodiments, the protective film 3 can also be made of other insulating, corrosion-resistant, and heat-resistant plastic materials.

[0041] Please also read Fig. 9 , assembly holes 31 are provided at both ends of the protective film 3. After the protective film 3 is bent, the pulling portion 213 and the guiding portion 212 pass through the assembly holes 31 and the fixing holes 111 in sequence, and the sleeve portion 211 is inserted into the assembly holes 31 and the fixing holes 111. Through the cooperation of the assembly holes 31 and the fixing columns 21, the protective film 3 is tightly attached to the deformable plate 2 to enhance protection. The number of assembly holes 31 at both ends of the protective film 3 is 2, respectively, to further improve the degree of tightness. In another embodiment, the protective film 3 can also be fixed to the deformable plate 2 by glue or other fixing methods.

[0042] To summarize, the present application provides a layer plate assembly for a battery restraint tray, in which a deformable plate 2 is added to the clamping plane of the layer plate 1 so as to fully fit the battery and enhance the restraint effect of the battery restraint tray. The protective film 3 can isolate the battery from the deformable plate 2 and prevent the electrolyte leaking out after the battery is squeezed from adhering to the deformable plate 2, thereby protecting the deformable plate 2 and extending its service life.
