[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] Please refer to the following Figure 1-3 A battery assembly 100 according to an embodiment of the present utility model is described.

[0029] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, the battery assembly 100 includes a battery 10 and a mounting bracket 20. Specifically, the battery 10 is provided with a negative terminal 11; the battery 10 is disposed on the mounting bracket 20, and the mounting bracket 20 is provided with a grounding structure 21, which is connected to the negative terminal 11, and the negative terminal 11 is grounded through the grounding structure 21.

[0030] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting bracket 20 is provided with a grounding structure 21, which is electrically connected to the negative terminal 11, and the battery 10 is fixed on the mounting bracket 20.

[0031] The battery assembly 100 of this invention features a grounding structure 21 on its bracket. The negative terminal 11 can be grounded through the grounding structure 21, eliminating the need for an additional wiring harness to ground the negative terminal 11. This reduces the number of components used and lowers production costs. Furthermore, directly connecting the negative terminal 11 to the grounding structure 21 eliminates the need for connecting the negative terminal 11 to the wiring harness, thus reducing assembly time and improving efficiency. Additionally, during battery maintenance, the connection between the grounding structure 21 and the negative terminal 11 is more stable than that of a wiring harness, ensuring the negative terminal 11 remains grounded and preventing separation of the grounding structure 21 from the negative terminal 11, thereby guaranteeing the safe operation of the battery 10.

[0032] Furthermore, since the negative terminal 11 is grounded, even if a fault occurs at the positive terminal, the current in the battery 10 will not form a closed circuit, thus preventing a short circuit and fire in the battery 10, and ensuring the safe use of the battery 10.

[0033] According to an embodiment of the present invention, the battery assembly 100 has a grounding structure 21 on the bracket. The negative terminal 11 can be grounded through the grounding structure 21, thereby reducing the use of parts and reducing production costs. At the same time, it can reduce the assembly time of the battery assembly 100 and improve assembly efficiency.

[0034] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The grounding structure 21 includes an annular connecting portion 211, which is sleeved and fixed on the negative terminal 11. This ensures the fixing strength between the grounding structure 21 and the negative terminal 11, preventing separation of the negative terminal 11 from the grounding structure 21, and also ensuring the stability of the connection between the grounding structure 21 and the negative terminal 11, effectively avoiding poor contact between them.

[0035] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The connecting part 211 is formed as a clamp. Therefore, the clamp structure is simple and easy to process, which facilitates mass production. At the same time, the clamp installation method is simple, which makes it easy to fix the connecting part 211 to the negative terminal 11.

[0036] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3The clamp includes: a retaining ring 2111, a bolt 2112, and a nut 2113. The retaining ring 2111 is formed as a notched ring and is fitted onto the negative terminal 11. Both ends of the retaining ring 2111 are provided with adjusting plates extending radially outward along the retaining ring 2111, and the adjusting plates are provided with through holes. The bolt 2112 passes through the through holes of the two adjusting plates. The nut 2113 is threadedly connected to the bolt 2112.

[0037] In this way, the retaining ring 2111 can engage the negative terminal 11 inside the retaining ring 2111, thereby facilitating the engagement of the clamp and the negative terminal 11. The bolt 2112 and the nut 2113 can adjust the relative distance between the two adjusting plates, thereby controlling the size of the hole in the retaining ring 2111, and thus controlling the tightness of the retaining ring 2111 and the negative terminal 11. Therefore, it can effectively prevent the clamp and the negative terminal 11 from separating.

[0038] For example, such as Figure 2 and Figure 3 As shown, the retaining ring 2111 is formed as an open ring on the rear side. The retaining ring 2111 is open on both the upper and lower sides. The negative terminal 11 is inserted into the radial inner side of the retaining ring 2111. Both ends of the rear side of the retaining ring 2111 have adjustment plates extending rearward in the front-rear direction. The adjustment plates are provided with through holes that penetrate the adjustment plates in the left-right direction. The bolt 2112 is inserted into the through holes of the two adjustment plates. The nut 2113 is screwed to the left end of the bolt 2112.

[0039] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The mounting bracket 20 also includes a tray 22, on which the battery 10 is supported, and a grounding structure 21 connected to the tray 22. Thus, the tray 22 provides installation space for the battery 10, facilitating its placement. Simultaneously, the grounding structure 21 is grounded through the tray 22, eliminating the need for additional structures to ground it, thereby enhancing the functional integration of the tray 22.

[0040] For example, such as Figure 1 and Figure 2 As shown, the tray 22 is arranged horizontally, the grounding structure 21 extends in the vertical direction, the lower end of the grounding structure 21 is connected to the tray 22, and the upper end of the grounding structure 21 extends upward.

[0041] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 3 The grounding structure 21 includes: a first pole segment 212, a second pole segment 213, and a connecting part 211, one end of the first pole segment 212 (e.g., Figure 1 The lower end of the first rod segment 212 shown is connected to the periphery of the tray 22, and the other end (as shown) Figure 1The upper end of the first rod segment 212 shown) is along the height direction of the battery 10 (e.g., Figure 1 The battery 10 shown extends away from the tray 22 in the vertical direction; the second rod segment 213 and the other end of the first rod segment 212 (as shown) Figure 1 The upper end of the first rod segment 212 shown is connected to the battery 10 and is located on the side of the battery 10 away from the tray 22 (e.g., Figure 1 The upper side of the battery 10 shown); the connecting part 211 is connected to the end of the second rod segment 213 away from the first rod segment 212 (e.g., the upper side of the battery 10 shown); Figure 1 (The rear end of the second rod segment 213 shown) has a connecting part 211 for connecting the negative terminal 11.

[0042] In this way, the first segment 212 facilitates the connection of the connecting part 211 to the negative terminal 11 via the second segment 213, thereby reducing the distance between the connecting part 211 and the negative terminal 11 and making the connection between the connecting part 211 and the negative terminal 11 easier. The second segment 213 avoids the battery 10, thereby preventing the connecting part 211 from colliding with the battery 10, thus ensuring that the battery 10 can be properly fixed to the tray 22. The connection part 211 is positioned reasonably, thereby ensuring that the connection part 211 can be properly connected to the negative terminal 11.

[0043] For example, such as Figure 1 and Figure 3 As shown, the first rod segment 212 extends in the vertical direction, the lower end of the first rod segment 212 is connected to the front edge of the tray 22, the upper end of the first rod segment 212 extends upward, the second rod segment 213 extends in the front-back direction, the front end of the second rod segment 213 is connected to the upper end of the first rod segment 212, the rear end of the second rod segment 213 extends backward, and the connecting part 211 is connected to the rear end of the second rod segment 213.

[0044] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The grounding structure 21 is provided with a reinforcing rib 214, which extends from the first pole segment 212 to the second pole segment 213. Therefore, the reinforcing rib 214 can strengthen the connection between the first pole segment 212 and the second pole segment 213, thereby effectively preventing breakage at the connection point and ensuring the strength of the grounding structure 21.

[0045] According to some embodiments of the present invention, referring to Figure 1 and Figure 2The tray 22 has multiple limiting plates 221 around its periphery. That is, there may be two, three, four, or more limiting plates 221. These limiting plates 221 are arranged at intervals around the circumference of the battery 10, defining an open installation space on the upper side where the battery 10 is located. Therefore, the limiting plates 221 can confine the battery 10 within the installation space, effectively preventing the battery 10 from separating from the mounting bracket 20. Simultaneously, the limiting plates 221 can also limit the battery 10, effectively preventing it from shaking within the installation space and thus effectively protecting the battery 10.

[0046] For example, such as Figure 1 and Figure 2 As shown, the limiting plate 221 extends in the vertical direction. The lower end of the limiting plate 221 is connected to the tray 22, and the upper end of the limiting plate 221 extends upward. There are three limiting plates 221. The three limiting plates 221 are respectively arranged on the left, right and rear sides of the battery 10. The three limiting plates 221 define the upper open installation space, and the lower end of the battery 10 is fixed in the installation space.

[0047] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The mounting bracket 20 is a sheet metal part. This ensures that the negative terminal 11 is grounded through the mounting bracket 20, thereby protecting the battery 10.

[0048] According to a second aspect embodiment of the present utility model, the vehicle 1000, with reference to... Figure 1 , Figure 2 and Figure 3 The system includes: a vehicle body 200; a battery assembly 100 of the first aspect of this embodiment, with a mounting bracket 20 disposed on the vehicle body 200 and grounded through the vehicle body 200.

[0049] For example, such as Figure 1 As shown, the mounting bracket 20 is fixed to the vehicle body 200 via the tray 22. The battery 10 is located on the upper side of the mounting bracket 20. The negative terminal 11 is connected to the tray 22 via the grounding structure 21. The tray 22 is connected to the vehicle body 200, and the vehicle body 200 is grounded, thereby grounding the negative terminal 11.

[0050] According to the embodiment of the present utility model, the vehicle 1000, by setting the battery assembly 100 of the first aspect embodiment above, provides a grounding structure 21 on the bracket, and the negative terminal 11 can be grounded through the grounding structure 21, thereby reducing the use of parts, reducing production costs, and at the same time, reducing the assembly time of the battery assembly 100 and improving assembly efficiency.
