[0023] Figure 1In the utility model, the lining body is produced by two-color injection molding, and the soft rubber layer frame 1, the left frame 2, the right frame 4, and the connecting strip 3 are injection molded into one piece. The connecting strip 3 connects the left frame 3 and the right frame 4 together. The connecting strip 3 is designed to be 0.5mm thick, which is convenient for bending during use. The material of the soft rubber layer frame 1 is TPE, which is designed to be 2mm thick; the material of the left frame 2, the connecting strip 3, and the right frame 4 is PP. The structure of the left frame 2 is the same as that of the right frame 4. The soft rubber layer frame includes a frame edge, a horizontal rib C connected to the middle of the frame edge, and a vertical rib D. The horizontal rib C and the vertical rib D are connected by a connecting ring 9, and the inner and outer surfaces of the soft rubber layer frame are both flat.

[0024] The left frame 2 includes a frame edge, a horizontal rib A connected to the middle of the frame edge, and a vertical rib B. When the left frame 2 and the right frame 4 are bent along the end of the connecting strip 3 to form a receiving groove (i.e., a U-shaped liner 5), the inner surface of the front and rear groove walls of the receiving groove is the soft rubber layer frame 1, the outer surface of the front and rear groove walls of the receiving groove is the left / right frame, and the bottom surface of the receiving groove is the connecting strip 3.

[0025] Figure 2 It is a structural schematic diagram of the lining body of the utility model in a naturally flattened state. The planes where the frame edge of the left frame 2, the inner surfaces of the horizontal ribs A and the vertical ribs B are located are located in the same plane, and the planes where the frame edge of the left frame 2 and the outer surfaces of the horizontal ribs A are located are higher than the outer surfaces of the vertical ribs B. The thickness of the frame edge of the left frame 2 is equal to the thickness of the horizontal ribs A, and the thickness of the horizontal ribs A is greater than the thickness of the vertical ribs B. The vertical ribs B are connected to the horizontal ribs A through a reinforcing ring, and the inner surface of the reinforcing ring is located in the same plane as the plane where the frame edge is located, and the outer surface of the reinforcing ring is lower than the plane where the frame edge is located.

[0026] Figure 3 , 4 In the embodiment, the U-shaped liner 5 can wrap the pole group 6; the plate ear 7 is fixed on the pole group 6. The soft rubber layer frame 1 contacts the pole group 6 to prevent the pole group 6 from being scratched. Under complex working conditions, the battery vibrates greatly, and the soft rubber layer frame 1 has a buffering effect on the pole group 6, which can effectively prevent the plate ear 7 from breaking.

[0027] Figure 5 In the figure, the U-shaped liner 5 wraps the pole group 6 and is installed in the battery slot 8; the pole group 6 is designed to be tightly assembled according to 103%, because the compression of the soft rubber layer frame 1 can improve the bulging phenomenon of the side of the battery slot 8.
