[0052] like Figure 4 As shown, according to some embodiments of the present invention, the body 111 includes: a support plate 1111 and an extension plate 1112 .

[0053] The extension plates 1112 are located on both sides of the width of the support plate 1111 and extend away from the support plate 1111 . The support plate 1111 , the extension plates 1112 and the cover plate 113 define a first protection portion.

The two sides of the support plate 1111 in the width direction are suitable for being connected to the free ends of the extension plates 1112, so that the support plate 1111, the extension plate 1112 and the cover plate 113 can jointly define a wiring space with a certain length, width and height. Therefore, the first protective part can provide sufficient space for the integrated arrangement of multiple wiring harnesses 13, and the support plate 1111, the extension plate 1112 and the cover plate 113 can provide good protection for the wiring harnesses 13.

[0055] In addition, in some specific embodiments of the present invention, a smooth arc surface is formed between the surfaces of the extension plate 1112 and the support plate 1111 facing each other to protect the wiring harness 13 from scratches, which is beneficial to extending the life of the wiring harness 13 and improving the working reliability of the energy storage device 1.

[0058] Specifically, extension plates 1112 are provided on both sides of the support plate 1111 in the width direction, and a wiring harness via hole may be formed on at least one extension plate 1112. The wiring harness via hole may penetrate the extension plate 1112 along the thickness direction of the extension plate 1112 to avoid the wiring harness 13. In this way, under the premise of ensuring that the wiring harness 13 is integrated in the first protective portion, the requirement that at least part of the wiring harness 13 can pass through the wiring harness via hole to be connected to some other components in the energy storage device 1 (such as BMS17) can be met, thereby ensuring the normal operation of some other components in the energy storage device 1.

[0059] In addition, in some specific embodiments of the present invention, the wiring harness through holes are multiple and spaced apart on the extension plate 1112 , so as to meet the connection requirements between the wiring harness 13 and different components in the energy storage device 1 .

[0060] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, a fixing portion is further provided on a side of the cover plate 113 facing away from the body 111 , and the fixing portion is used to fix the busbar.

[0061] Specifically, the fixing part can be arranged on the side of the cover plate 113 away from the body 111, and the structural shape of the fixing part can be set according to the shape of the busbar. For example, the fixing part can be constructed as a stud, and the busbar is provided with a threaded hole suitable for cooperating with the stud, so that the fixing part can fix the busbar. By setting the fixing part, the integration of the busbar with the wiring harness 13, electrical parts and other components can be improved, and the space utilization rate of the energy storage device 1 can be further improved. At the same time, the busbar and the wiring harness 13 are separated by the cover plate 113, which also fully guarantees the working safety of the busbar and the wiring harness 13.

[0062] In addition, in some specific embodiments of the present invention, the fixing portion is constructed as a clamping ring structure or a clamping plate structure to correspondingly clamp or clamp the busbar to achieve fixation.

[0063] like Figure 4 As shown, according to some embodiments of the present invention, the second protection portion 112 is constructed as at least one spacing structure, and the spacing structure is suitable for being set on the connector 15 of the energy storage device 1 to separate the connector 15 from surrounding components.

[0064] Specifically, the spacing structure can be arranged on a side of the support plate 1111 that is away from the first protective portion in the thickness direction. The spacing structure extends away from the support plate 1111 and forms a accommodating cavity, and the accommodating cavity is open in a direction away from the main body 111. The spacing structure is sleeved on the connector 15, and the connector 15 is accommodated in the accommodating cavity, so that the spacing structure can separate the connector 15 from surrounding components, isolate high and low voltages, and prevent people and objects from contacting the connector 15, thereby protecting the connector 15 and the high-voltage electrical circuit of the energy storage device 1, thereby improving the working safety of the energy storage device 1.

[0065] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the outer contour of the spacing structure is consistent with at least a portion of the outer contour of the connector 15 .

By setting the outer contour of the spacing structure to be consistent with at least part of the outer contour of the connector 15, the distance between the inner surface of the spacing structure and the outer surface of the connector 15 can be smaller or more closely fitted. In this way, on the one hand, the space occupied by the spacing structure can be saved, the space utilization rate can be improved, and the energy storage density of the energy storage device 1 can be optimized; on the other hand, the spacing structure can play a certain limiting role on the connector 15, which can improve the installation stability of the connector 15 and further improve the safety of the energy storage device 1.

[0067] In addition, in some specific embodiments of the present invention, the spacing structure is constructed as two spacing structures arranged at intervals in the extension direction of the main body 111, one of which separates the high-voltage component from the surrounding components, and the other separates the low-voltage component from the surrounding components, so as to further strengthen the protection and isolation of high and low voltages.

The positive terminal and the negative terminal of the connector 15 can be respectively accommodated in different separation cavities. In this way, the partition 1121 separates the positive terminal from the negative terminal of the connector 15, and can protect the positive terminal and the negative terminal respectively, thereby improving the working independence and safety of the positive terminal and the negative terminal, and further improving the working reliability of the connector.

[0070] In addition, in some specific embodiments of the present utility model, the partition 1121 includes a first plate 11211, a second plate 11212 and a third plate 11213, wherein one end of the first plate 11211 and the second plate 11212 are both connected to the inner surface of the connector 15, and one end of the first plate 11211 and the second plate 11212 are spaced apart in the circumferential direction of the connector 15, the other ends of the first plate 11211 and the second plate 11212 are connected to the same end of the third plate 11213, and the other end of the third plate 11213 extends in a direction away from the support plate 1111. In this way, a cavity is formed between the first plate 11211 and the second plate 11212, and the first plate 11211, the second plate 11212 and the third plate 11213 can jointly play a good supporting and reinforcing role on the partition structure, which can improve the working reliability and life of the partition structure and save maintenance costs.

[0071] like Figure 4 As shown, according to some embodiments of the present invention, connecting parts 114 are provided at both ends of the length of the body 111 , and the connecting parts 114 are connected to the box body 12 .

[0072] Specifically, the connection part 114 can be constructed as two and located at the two ends of the body 111 in the length direction. The connection part 114 is suitable for connecting with the box 12, so that the connection part 114 can realize the installation of the protective integrated component 11 on the box 12 as a whole. The connection method between the connection part 114 and the box 12 can be snap-fit ​​or connected by fasteners 115, etc., to improve the installation and disassembly convenience of the connection part 114 and the box 12, which is conducive to improving assembly efficiency and maintenance convenience. In addition, the connection part 114 can also play a good supporting role on the body 111 at both ends of the body 111, which can improve the carrying capacity of the body 111 for the wire harness 13.

[0073] In addition, in some specific embodiments of the present invention, the connection parts 114 at both ends of the main body 111 are tilted away from the main body 111 in a direction away from each other, which can improve the mechanical properties of the assembly structure of the connection parts 114 and the main body 111 and increase the life of the protective integrated component 11.

[0074] In other specific embodiments of the utility model, reinforcing ribs 1141 are provided on the connecting portion 114.
