[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] In order to solve the problem of low strength of existing PP material battery shells, the present application provides a reinforcing member on the pressure-bearing surface of the battery shell to enhance the rigidity of the shell and reduce battery swelling.

[0022] Figure 1 The overall structural diagram of the LDC deep cycle PP trough is shown; Figure 1 In the embodiment, the LDC deep cycle PP material tank body includes a main body 100 and a limiting mechanism 200 arranged outside the pressure surface of the main body 100, and the limiting mechanism 200 can limit the pressure surface from deforming outward.

[0023] Figure 2 shows a schematic structural diagram of the body 100; Figure 2 In the figure, the main body 100 includes a frame 110 and a pressure surface 120 movably connected to the frame 110; the traditional integrated structure is changed, and the pressure surface 120 and the frame 110 are divided into two parts. This structure can ensure that the pressure surface 120 does not affect the overall structure of the frame 110 when it is deformed outward; it should be noted that the pressure surface 120 can still ensure the original protection effect after installation, and does not affect the use of the battery under normal conditions.

[0024] Figure 3 A schematic cross-sectional structure diagram of the pressure surface 120 is shown; Figure 3In the figure, the pressure surface 120 has a plurality of groups of equidistantly arranged vertical ribs 121 and transverse ribs 122, and the vertical ribs 121 and the transverse ribs 122 are arranged perpendicularly to form a mesh structure. The mesh structure formed by the cooperation of the vertical ribs 121 and the transverse ribs 122 can increase the resistance that the pressure surface 120 has to overcome when deforming along the thickness direction, thereby preventing the pressure surface 120 from deforming in the thickness direction.

[0025] Figure 4 The schematic diagram of the structure of the limiting mechanism 200 is shown; the limiting mechanism 200 includes a plurality of groups of intercepting members 210 arranged equidistantly along the height direction of the pressure surface 120 and a plurality of groups of conducting members 220 arranged equidistantly along the length direction of the pressure surface 120, the intercepting members 210 are connected to the frame 110, the conducting members 220 are arranged between the intercepting members 210 and the pressure surface 120 and vertically contact the pressure surface 120, and the intercepting members 210 are of a catenary structure; since the intercepting members 210 are connected to the frame 110 but not directly connected to the pressure surface 120, a line can be formed in the deformation direction of the pressure surface 120. A protective line is used to limit the deformation of the pressure surface 120, and the intercepting member 210 is a catenary structure, so that each point reaches a state of force balance. When any point is subjected to force, it will return to a state of balance to increase the resistance that needs to be overcome for the deformation of the pressure surface 120. It should be noted that the conductive member 220 is arranged between the intercepting member 210 and the pressure surface 120. It is only necessary to ensure that the two ends of the conductive member 220 respectively resist the intercepting member 210 and the pressure surface 120 to form force conduction. There is no need to fix the conductive member 220 to the pressure surface 120 and the intercepting member 210 to ensure simple subsequent disassembly.

[0026] Figure 5 A schematic structural diagram showing the connection of two adjacent groups of intercepting members 210 is shown; Figure 5 In the figure, a connecting piece 230 is connected between two adjacent groups of intercepting pieces 210, so that the multiple groups of intercepting pieces 210 form a protective surface for limiting the pressure surface 120; since the multiple groups of intercepting pieces 210 are interconnected and form a whole, the limiting effect on the pressure surface 120 can be further increased.

[0027] A power battery, comprising the above-mentioned LDC deep cycle PP material tank body.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
