[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] The cover plate of the embodiment of the present utility model comprises: a plate body 1 and a bent plate 2, wherein a bent portion 11 is provided at the bottom of the plate body 1;

[0032] The bending plate 2 is provided at the bottom of the plate body 1, and the bending portion 11 and the bending plate 2 are arranged at intervals relative to each other in the extension direction of the plate body 1. There are multiple bending plates 2, and the multiple bending plates 2 are arranged at intervals in the extension direction of the plate body 1.

[0033] The sizes of the multiple bent plates 2 in the extending direction of the plate body 1 are the same or different.

[0034] Specifically, if Figures 1 to 6 As shown, the extension direction of the plate body 1 is the left-right direction, and the length direction is the extension direction. The bending portion 11 is provided at the right end of the plate body 1, and the bending portion 11 is bent downward. The bending plate 2 is provided at the bottom of the plate body 1, and the bending plate 2 is provided at the left end of the plate body 1, so as to facilitate the integral insulation protection of the internal module in the battery plug box after installation. The bending portion 11 is divided to ensure that the entire copper busbar is wrapped. The bending portion 11 of the plate body 1 and the bending plate 2 can effectively protect the exposed metal of the copper busbar. It plays the role of insulation protection and preventing short circuits. The plate body 1 at the connection between the plate body 1 and the bending plate 2 continues to extend 10 mm to the left to further protect the copper busbar or metal wire.

[0035] The cover plate of the embodiment of the utility model is formed into one piece by integrating the original split multiple integral cover plates to cover the four modules in the battery plug box as a whole, completing the one-time assembly and improving the assembly efficiency. It can cover the four modules as a whole and cover the gaps between the modules to prevent foreign objects from entering the gaps.

[0036] The cover plate of this embodiment of the utility model, by providing a bent plate 2 and a bent portion 11 in the left and right directions, can effectively protect the exposed metal of the copper busbar, providing insulation and preventing short circuits. The bent portion 11 also prevents dust from entering the battery compartment through the bottom of the plate 1. Furthermore, the bent portion 11 provides a certain degree of protection for the battery compartment. For example, by bending downward, it prevents dust from entering the non-cable area of ​​the battery compartment. It also protects the copper wires within the battery compartment, preventing the exposed conductive metal.

[0037] In some embodiments, the dimension of the bent plate 2 in the thickness direction of the plate body 1 is 25 mm to 35 mm.

[0038] Specifically, if Figures 1 to 6 As shown, the bent plate 2 is bent downward by 25 mm to 35 mm. Furthermore, the bent plate 2 is bent downward so that it extends into the battery compartment, thereby ensuring a stable connection between the battery compartment and the bent plate 2. The downwardly bent plate 2 and the bent portion 11 can effectively protect the exposed metal of the copper busbar, providing insulation and preventing short circuits.

[0039] In some embodiments, the cover plate further includes a sealing component 3 , and a groove is provided at the bottom of the plate body 1 for installing the sealing component 3 , and the sealing component 3 partially extends out of the groove.

[0040] Specifically, if Figures 1 to 6 As shown, the sealing component 3 is arranged at the bottom of the plate body 1, that is, the sealing component 3 is arranged in the direction of the plate body 1 close to the battery insertion box. The upper end of the sealing component 3 extends into the plate body 1, and the lower end of the sealing component 3 contacts the battery insertion box. The lower end of the battery insertion box is provided with a first groove corresponding to the sealing component 3 to accommodate the lower end of the sealing component 3, thereby sealing the gap between the plate body 1 and the battery insertion box.

[0041] In some embodiments, the sealing component 3 includes a sealing ring 32 and an adhesive 31 . The sealing ring 32 is partially disposed in the groove. There are multiple adhesives 31 , which are spaced apart in the circumferential direction of the plate 1 .

[0042] Specifically, if Figures 1 to 6 As shown, the sealing ring 32 can be annular, or strip-shaped, or belt-shaped. A first groove corresponding to the sealing ring 32 is provided at the lower end of the battery inserting box.

[0043] When the sealing ring 32 is annular, the lower end of the plate body 1 contacts the battery compartment to seal it. At this point, the wires of the modules inside the battery compartment do not protrude from the gap between the plate body 1 and the compartment. In existing battery compartment structures, however, because wires extend from between the plate body 1 and the compartment, the sealing ring 32 is designed in a strip or ribbon shape. The unsealed portion between the plate body 1 and the compartment extends beyond the compartment and the plate body 1, facilitating connection between the battery modules inside the compartment and external electrical equipment.

[0044] Alternatively, the sealing ring 32 is annular, and the wire extends from between the board body 1 and the battery plug box, and then the sealing ring 32 on the wire board body 1 presses the wire downward, pressing the wire onto the battery plug box, and reducing the gap between the wire and the board body 1 or the battery plug box as much as possible to prevent dust from entering the battery plug box.

[0045] The adhesive 31 extends vertically, with its upper end connected to the lower end of the board 1 and its lower end bonded to the battery compartment, thereby connecting and securing the battery compartment to the board 1. A blind hole corresponding to the adhesive 31 is provided at the upper end of the battery compartment, allowing the lower end of the adhesive 31 to adhere to the bottom of the blind hole. This minimizes any gaps between the board 1 and the battery compartment.

[0046] In some embodiments, the cover plate further includes a limiting member 4 , which is connected to the bottom of the plate body 1 and extends in a direction away from the plate body 1 .

[0047] Specifically, if Figures 1 to 6 As shown, the limiting member 4 extends in the up-down direction to prevent the plate body 1 from contacting the modules in the battery compartment and to limit the plate body 1 to a certain extent. At the same time, the limiting member 4 is arranged at the lower end of the plate body 1, that is, the bottom of the plate body 1. Due to gravity, the plate body 1 has a tendency to move downward, so that the sealing ring 32 uses the area maintained under pressure, thereby improving the stability and safety of the seal.

[0048] Furthermore, the radial dimension of the limiting member 4 gradually decreases in the direction away from the plate body 1. At the same time, the material of the limiting member 4 can be rubber material to reduce the cost and volume of the limiting member 4.

[0049] Furthermore, the plate body 1 is provided with an air vent, and the stopper 4 is provided with an air guide hole connected to the air vent. The air guide hole is divided into a first bending section and a second bending section that are connected to each other. The shape of the first bending section and the second bending section is N-shaped. By setting it to N-shaped, dust can be collected at the bending part. At the same time, when cleaning, water flushing or detergent is used for cleaning, which ensures ventilation and avoids

[0050] Furthermore, there are multiple limiters 4, which are spaced apart on the plate 1 to increase the area for movement under the plate 1 and ensure adequate ventilation of the battery compartment, thereby releasing the heat from the batteries in a timely manner.

[0051] The battery plug box of the embodiment of the utility model comprises:

[0052] Cover plate, the cover plate is any of the above cover plates;

[0053] The lower box body is connected to the cover plate, and a plurality of module installation slots arranged at intervals are provided in the box body;

[0054] A plurality of battery modules are installed in a one-to-one correspondence with the plurality of module installation slots.

[0055] Specifically, if Figures 1 to 6 As shown, by providing a mounting groove to install the battery module, the cover is connected to the battery plug box to seal the battery plug box to prevent dust from entering. Further, the plate body 1 is provided with an upper threaded hole 12 so that a bolt can be connected to the battery plug box through the upper threaded hole 12.
