Without connecting the hanging rope 20 to the shell 10 and then transporting it to the sewing process for sewing, the operation complexity is reduced, the assembly process is simplified, and the installation convenience is improved.

[0048] Specifically, in the embodiment of the application, the shell 10 is provided with a cavity for accommodating the battery cell module and the wiring layout. The shell 10 can be a two-part split structure or an integral structure, and the specific type of the shell 10 can not be limited in the embodiment of the application.

[0049] In the embodiment of the application, for example, the other end of the hanging rope 20 can be provided with a thimble, so that the hanging rope 20 extending out of the shell 10 is convenient for the user to grasp. For example, the hanging rope 20 can be made of polyester, nylon, nylon or cotton, in addition, the hanging rope 20 can also be made of rubber or silicone, and the specific material of the hanging rope 20 can not be limited in the embodiment of the application.

[0050] For example, in the embodiment of the present application, the opening 13 can be a long strip-shaped opening, or a circular or elliptical opening 13, which can be set according to actual needs, and the specific shape of the opening 13 is not limited in the embodiment of the present application.

[0051] Optionally, in the embodiment of the present application, one end of the hanging rope 20 is provided with a clamping portion 21 clamped to the inner side 11 of the shell 10. In this way, the one end of the hanging rope 20 can be more stably clamped to the inner side 11 of the shell 10 at the opening 13 through the clamping portion 21, improving the connection reliability of the hanging rope 20.

[0052] In the embodiment of the present application, optionally, one end of the hanging rope 20 is arranged in a stack and is folded to form the clamping portion 21. For example, one end of the hanging rope 20 can be folded and then sewn, and then the end portion at the sewing line is folded to form the clamping portion 21. In this way, the size of the clamping portion 21 is greater than the size of the opening 13, so that the clamping portion 21 can be more firmly clamped to the inner side 11 of the shell 10, improving the clamping firmness between the hanging rope 20 and the shell 10, and the manufacturing is simple and the operation is simple.

[0053] For example, in the installation process, the hanging rope 20 with the clamping portion 21 can be first manufactured, and then Figure 3 the hanging rope 20 is arranged in the opening 13 from top to bottom along the arrow direction, so that one end of the hanging rope 20 is clamped to the inner side 11 of the shell 10.

[0054] Optionally, in the embodiment of the present application, the battery pack surface shell assembly further comprises a limiting column 14 connected to the inner side 11 of the shell 10 near the opening 13; one end of the hanging rope 20 is provided with a limiting hole 22 clamped to the limiting column 14. In this way, the limiting hole 22 of one end of the hanging rope 20 is sleeved on the limiting column 14, realizing the more stable clamping effect of the hanging rope 20 and the inner side 11 of the shell 10. For example, the limiting column 14 protrudes from the inner side 11 of the shell 10, and the limiting column 14 extends along the vertical direction of the paper. Figure 5

In this way, the double-layered first flange 23 and second flange 24 can improve the thickness and strength of one end of the hanging rope 20, so that the connection between the hanging rope 20 and the limiting column 14 has better connection strength and wear resistance. Moreover, the side of the second flange 24 away from the first flange 23 is connected to the hook 141, which avoids the first flange 23 and the second flange 24 from being separated from the limiting column 14, and improves the connection reliability of the hanging rope 20.

[0056] In the embodiment of the present application, for example, the width of the first flange 23 and the second flange 24 can be smaller than the width of the other end of the body of the hanging rope 20. In this way, when the hanging rope 20 is installed, as shown in the arrow direction, the hanging rope 20 can be arranged in the opening 13 from bottom to top, so that the limiting hole 22 on the first flange 23 and the second flange 24 of the hanging rope 20 is connected to the limiting column 14. Figure 5

[0057] In addition, the width of the first flange 23 and the second flange 24 can also be greater than or equal to the width of the other end of the body of the hanging rope 20. The hanging rope 20 can be arranged in the opening 13 from top to bottom, and the limiting hole 22 on the first flange 23 and the second flange 24 of the hanging rope 20 is connected to the limiting column 14 on the inner side 11 of the shell 10. The specific size of the first flange 23 and the second flange 24 is not limited in the embodiment of the present application, and in addition, the specific installation method of the hanging rope 20 can also not be limited in the embodiment of the present application, which can be operated according to actual needs.

In this way, the hanging part 25 can be sleeved on the limiting shaft 30 along the second direction X, so as to realize the stable connection of the hanging rope 20 and the inner side 11 of the shell 10.

[0059] In the embodiment of the present application, optionally, the battery pack surface shell assembly further comprises a mounting assembly connected to the inner side 11 of the shell 10 close to the opening 13; the hanging part 25 is provided with a through hole 251 penetrating along the second direction X, and the limiting shaft 30 is connected to the mounting assembly and penetrates the through hole 251. In this way, the mounting assembly provides a stable and reliable installation for the limiting shaft 30, which facilitates the assembly of the limiting shaft 30.

[0060] ​Optionally, in the embodiment of the present application, the mounting assembly comprises the fixed member 15 and the limiting member arranged at intervals, the limiting shaft 30 comprises a first shaft rod 31 extending along the second direction X and a second shaft rod connected to the first shaft rod 31; the first shaft rod 31 is arranged through the through hole 251 of the fixed member 15 and the hanging portion 25, and the second shaft rod is clamped to the limiting member. In this way, the fixed member 15 provides a relatively stable mounting for the limiting shaft 30, and the limiting member limits the limiting shaft 30 to avoid deviation or even disengagement from the fixed member 15.

[0061] For example, in the embodiment of the present application, the fixed member 15 can be two fixed plates arranged at intervals, and mounting holes are arranged on the fixed plates. The hanging portion 25 can be arranged between the two fixed plates, and then the first shaft rod 31 is arranged through the mounting hole of one of the fixed plates, the through hole 251 of the hanging portion 25 and the mounting hole of the other fixed plate in sequence, so as to realize a relatively stable connection of the limiting shaft 30 to one end of the hanging rope 20.

[0062] Optionally, in the embodiment of the present application, the second shaft rod comprises a first limiting rod 32 and a second limiting rod 33 extending along the second direction X, and the second limiting rod 33 is connected to the first shaft rod 31 through the first limiting rod 32; the limiting member comprises a first limiting plate 16 and a second limiting plate 17 arranged at intervals, the first limiting rod 32 is clamped to the first limiting plate 16, and the second limiting rod 33 abuts against the second limiting plate 17. In this way, the first limiting plate 16 limits the first limiting rod 32 to avoid deviation of the first limiting rod 32 in a direction away from the fixed member 15, and the second limiting plate 17 limits the second limiting rod 33 to avoid deviation of the second limiting rod 33 in a direction away from the fixed member 15, so that the limiting shaft 30 has better stability.

[0063] In the embodiment of the present application, for example, as shown in Figure 9 The hanging rope 20 can be arranged through the opening 13 from top to bottom, or the hanging rope 20 can be arranged through the opening 13 from bottom to top, so that the hanging portion 25 is located between the two fixed plates of the fixed member 15. Then, the first shaft rod 31 is arranged through the through hole 251 of the fixed member 15 and the hanging portion 25, at this time, the second limiting rod 33 of the limiting shaft 30 is located above the first shaft rod 31 to avoid interference between the limiting shaft 30 and the first limiting plate 16. Then, as shown in Figure 10 the limiting shaft 30 is rotated clockwise, so that the second limiting rod 33 abuts against the second limiting plate 17, and the first limiting rod 32 is clamped to the first limiting plate 16, to realize a relatively stable mounting of the limiting shaft 30 and avoid shaking of the limiting shaft 30. For example, the second limiting plate 17 can be provided with a protruding clamping block, and the second limiting rod 33 is clamped to the clamping block to further improve the limiting effect of the second limiting rod 33.
