[0062] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0063] In this document, ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of the "second component", and the term "second component" itself does not imply the existence of the "first component".

[0064] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0065] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0066] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0067] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0068] The utility model provides a battery device, including a crossbeam 300 and a pull plate 400. The pull plate 400 can be made of metal, such as aluminum, or a plastic part or a composite material. The aluminum pull plate 400 is arranged on one side of the crossbeam 300 along the height direction DH. The aluminum pull plate 400 can be connected to the crossbeam 300 by riveting, bolts, welding or other methods to ensure that the entire battery pack has sufficient structural strength and stability.

[0069] The internal space of the battery device usually needs to be compactly designed to accommodate the battery cells to the maximum extent. In some embodiments, the electrical connector 200 extends from the top of the aluminum plate 400 to the side of the crossbeam 300. The electrical connector 200 can be a soft connection harness or a hard metal connection bar. The electrical connector 200 has a corner at the connection between the aluminum plate 400 and the crossbeam 300. The electrical connector 200 at the corner has a large contact area with the surrounding components, which is prone to friction and collision. In particular, it may be subject to vibration and impact during the driving of the vehicle, further exacerbating the wear of the electrical connector 200.

[0070] In the embodiment of the utility model, the electrical connector 200 is a high-voltage wire harness. The material of the high-voltage wire harness is copper. As can be seen from the above, the aluminum plate 400 is arranged above the crossbeam 300, and the corner of the electrical connector 200 directly contacts the aluminum plate 400. The hardness of the aluminum plate 400 is higher than that of the copper bar. The copper bar contacts the aluminum plate 400 and is easily worn.

[0071] The utility model provides a protective bracket 100 for protecting an electrical connector 200, wherein the electrical connector 200 has a first section 210 and a second section 220 for forming a corner. The protective bracket 100 can be connected to other structural members in the usage scenario, such as a crossbeam 300 of a battery device, a distribution box, a tray, etc. The protective bracket 100 can provide additional stability and support, and reduce damage caused by vibration or impact. The connection between the protective bracket 100 and other structures can be in the form of snap-on, screw-on, welding, or bonding. The protective bracket 100 is easy to install and disassemble, which is convenient for future maintenance and replacement.

[0072] like Figure 1-2As shown, in the present invention, the protective bracket 100 includes a first protective plate 110, which is used to be arranged on the inner side of the first section 210, that is, the first protective plate 110 is located on the side of the electrical connector 200 close to other structures (such as beams). The first protective plate 110 is provided with a plurality of first side plates 131 arranged relatively along the first direction D1, and the first side plates 131 are used to limit the first section 210. The first protective plate 110 and the first side plates 131 form a first slot 1101. In this embodiment, the first slot 1101 can be provided as one or more, so as to protect one or more electrical connectors 200 and avoid collision or wear between multiple electrical connectors 200. The second protective plate 120, the second protective plate 120 is connected to the first protective plate 110 and is used to be arranged on the inner side of the second section 220, that is, the second protective plate 120 is located on the side of the electrical connector 200 close to other structures (such as beams). The second protective plate 120 is provided with a plurality of second side plates 132 arranged opposite to each other along the first direction D1. The second protective plate 120 and the second side plates 132 form a second slot 1201.

Specifically, the first section 210 of the electrical connector 200 is provided in the first slot 1101, and the second section 220 is provided in the second slot 1201. The first slot 1101 and the second slot 1201 have the same extension direction as the electrical connector 200. Through the protective bracket 100 provided by the utility model, the electrical connector 200 can be fixed at a position with a corner to avoid contact with surrounding components, thereby reducing friction and collision and reducing wear of the electrical connector 200. The first protective plate 110 is arranged on the inner side of the first section 210, and the second protective plate 120 is arranged on the inner side of the second section 220, so as to separate the electrical connector 200 from other structures and reduce the wear on the electrical connector 200. By setting the first side plate 131 and the second side plate 132, the electrical connector 200 is limited, and the strength of the first protective plate 110 and the second protective plate 120 is improved, which plays the role of reinforcing ribs, and can provide additional protection for the electrical connector 200, avoiding direct collision between the electrical connector 200 and other structures within a certain range.
