Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to an anti-rotation bracket for a high-voltage connector and a battery pack. Background Technology

[0002] In the power battery pack of new energy vehicles, the high-voltage connector socket is the hub connecting the battery pack and the vehicle. Its safety and stability are crucial to the safety of both the battery pack and the vehicle. Currently, the high-voltage connector is generally electrically connected to the copper busbar inside the battery pack via bolts. This is prone to the copper busbar shaking or tilting, which reduces the electrical clearance and creepage distance between the positive and negative terminals of the power supply, failing to meet requirements such as UL2580, and thus affecting the stability of the electrical connection.

[0003] Therefore, in related technologies, anti-rotation brackets are usually provided for high-voltage connectors and copper busbars to achieve the connection between the two and prevent the copper busbar from shaking or tilting. Existing anti-rotation brackets generally include a base for high-voltage connectors to be inserted and connected, and a protective cover on the base. The copper busbar is usually inserted into the installation space formed by the base and the protective cover through a slot on the side of the protective cover to connect with the conductive post of the high-voltage connector.

[0004] In addition to the necessary installation structure, the installation between the protective cover and the base also requires a limiting structure to maintain a certain Z-axis installation space. At the same time, the base also needs to be equipped with a snap-fit ​​structure for snapping the wire harness connected to the high-voltage connector. The multiple structural settings make the overall structure of the anti-rotation bracket more complex, which is not conducive to the convenient use and development design of the anti-rotation bracket, and thus not conducive to the improvement of battery pack quality.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides an anti-rotation bracket for a high-voltage connector 100, which is beneficial for improving the quality of the battery pack.

[0034] In related technologies, within the power battery pack of new energy vehicles, the high-voltage connector 100 socket serves as the pivot connecting the battery pack and the vehicle. Its safety and stability are crucial to the safety of both the battery pack and the vehicle. Currently, the high-voltage connector 100 is generally electrically connected to the copper busbar inside the battery pack via bolts. This is prone to copper busbar wobbling and misalignment, reducing the electrical clearance and creepage distance between the positive and negative power terminals, failing to meet requirements such as UL2580, and thus affecting the stability of the electrical connection.

[0035] Therefore, in related technologies, anti-rotation brackets are usually provided for the high-voltage connector 100 and the copper busbar to realize the connection between the two and to prevent the copper busbar from shaking or tilting. Existing anti-rotation brackets generally include a base 200 for the high-voltage connector 100 to be inserted and connected, and a protective cover 300 provided on the base 200. The copper busbar is usually inserted into the installation space formed by the base 200 and the protective cover 300 through the slot 302c on the side of the protective cover 300 to connect with the conductive post 102 of the high-voltage connector 100.

[0036] In addition to the necessary installation structure, the installation between the protective cover 300 and the base 200 also requires a limiting structure to maintain a certain installation space in the Z direction. At the same time, the base 200 also needs to be equipped with a snap-fit ​​structure for snapping the wire harness connected to the high-voltage connector 100. The multiple structural settings make the overall structure of the anti-rotation bracket more complex, which is not conducive to the convenient use and development design of the anti-rotation bracket, and thus not conducive to the improvement of battery pack quality.

[0037] In view of this, in order to overcome the shortcomings of the related technology, the anti-rotation bracket of the high-voltage connector 100 in this embodiment is combined with... Figures 1 to 11 As shown, the overall design includes a base 200 and a protective cover 300, as well as a snap-fit ​​assembly disposed between the base 200 and the protective cover 300.

[0038] The snap-fit ​​assembly includes a snap-fit ​​part and a limiting part on the base 200, and a snap-fit ​​hole 3011 and a limiting mating part on the protective cover 300. The limiting part has a snap-fit ​​groove 2021 for snapping the high-voltage wire harness. Furthermore, along the height direction of the base 200, the snap-fit ​​part snaps into the snap-fit ​​hole 3011, and the limiting part abuts against the limiting mating part to restrict the movement of the protective cover 300 in the height direction of the base 200.

[0039] Therefore, by engaging the snap-fit ​​part into the snap-fit ​​hole 3011 along the height direction of the base 200, and with the limiting part abutting against the limiting mating part, the two together can restrict the movement of the protective cover 300 in the height direction of the base 200. This not only allows for convenient disassembly and assembly between the base 200 and the protective cover 300, but also ensures that the two maintain a certain installation space in the height direction of the base 200, thereby ensuring that the connection requirements of the high-voltage connector 100 and the conductive busbar 400 are met. At the same time, a snap-fit ​​groove 2021 is provided on the limiting part. Compared with the traditional method where the limiting structure and the snap-fit ​​groove 2021 structure are separate, this not only enables the snap-fit ​​fixing of the high-voltage wire harness, but also simplifies the structure, improves the ease of use of the anti-rotation bracket, and facilitates the development and design of the anti-rotation bracket, thereby contributing to the improvement of battery pack quality.

[0040] Based on the above overview, specifically, the high-voltage wiring harness mentioned above is the high-voltage wiring harness led out from the high-voltage connector 100. It should also be noted that the directional descriptions in this embodiment are merely illustrative examples. In actual implementation, the directional descriptions in this embodiment will vary depending on the orientation of the base 200; that is, the directions in this embodiment refer to a relative coordinate system with the base 200 as the reference.

[0041] Continue to combine Figures 1 to 8 As shown, in some exemplary embodiments, the limiting portion includes a first limiting member 202 and a second limiting member 203 disposed on the base 200. The first limiting member 202 and the second limiting member 203 are arranged at intervals along the width direction of the base 200, and a slot 2021 is provided on the first limiting member 202. Furthermore, the limiting mating portion includes a limiting mating surface 303 and a limiting mating member 304 disposed on the protective cover 300. Along the height direction of the base 200, the first limiting member 202 abuts against the limiting mating surface 303, and the second limiting member 203 abuts against the limiting mating member 304.

[0042] It is understandable that the limiting part includes a first limiting member 202 and a second limiting member 203 arranged at intervals along the width direction of the base 200, and the limiting mating part includes a limiting mating surface 303 and a limiting mating member 304. The structure is simple and easy to implement.

[0043] Continue to combine Figures 1 to 8 As shown, in some exemplary embodiments, the base 200 is provided with two connector sockets 204 spaced apart along the length of the base 200, and a mounting groove 205 communicating with each connector socket 204.

[0044] The conductive posts 102 of the high-voltage connector 100 are inserted into the connector sockets 204 respectively. The mounting slots 205 are used to install the conductive busbars 400 that are connected to the corresponding conductive posts 102. Along the length of the base 200, the snap-fit ​​part is located in the middle of the two mounting slots 205. By setting the mounting slots 205, the rotation of the copper busbars and the high-voltage connector 100 during installation can be prevented to a certain extent, avoiding installation misalignment, thus facilitating the arrangement and installation of the conductive busbars 400.

[0045] Specifically, the conductive busbar 400 in this embodiment can be a copper busbar connecting the cell modules in the battery pack and the high-voltage connector 100. For related structures not mentioned in the high-voltage connector 100 of this embodiment, refer to high-voltage connection sockets or various structures in the high-voltage connector 100 known to those skilled in the art, such as a connector body 101 and a plug-in interface connected to the entire vehicle assembly. This plug-in interface and the conductive posts 102 of this embodiment are respectively located at both ends of the connector body 101 along its length.

[0046] In some exemplary embodiments, the snap-fit ​​portion includes two hooks 201 arranged opposite each other along the width direction of the base 200, the two hooks 201 abutting against the inner wall of the snap-fit ​​hole 3011 at least in the width direction of the base 200. The main advantage of this arrangement is that it can, to a certain extent, limit the protective cover 300 of the base 200 in the width direction of the base 200.

[0047] In addition, continue to combine Figures 2 to 8 As shown, in some exemplary embodiments, the protective cover 300 includes a top cover 301 and a sidewall of the top cover 301 facing the base 200, with a snap-fit ​​hole 3011 and a limiting engagement portion both provided on the top cover 301.

[0048] The inner wall of the top cover 301 is provided with a limiting plate 305 corresponding to the snap-fit ​​hole 3011, and the two ends of the snap-fit ​​hole 3011 along the length direction of the base 200 are respectively provided with limiting plates 305, and each limiting plate 305 abuts against each hook 201. Here, by setting the limiting plate 305, the base 200 can limit the protective cover 300 in the length direction of the base 200.

[0049] Continue to combine Figure 7 and Figure 8 As shown, in some exemplary embodiments, the sidewall is provided with slots 302c corresponding to each mounting groove 205, and each slot 302c is used for the corresponding conductive busbar 400 to pass through. It can be understood that the slots 302c can prevent the conductive busbar 400 from moving or rotating, avoid the phenomenon of the conductive busbar 400 shaking or tilting, and thus ensure the stability of the electrical connection.

[0050] In specific implementations, in some exemplary embodiments, the opening direction of each connector socket 204 is arranged along the height direction of the base 200, and the sidewalls include two first sidewalls 302a spaced apart along the width direction of the base 200, and two second sidewalls 303b spaced apart along the length direction of the base 200. Each second sidewall 303b is provided with a slot 302c, and each first sidewall 302a is provided with a slot 302c corresponding to each mounting slot 205.

[0051] This arrangement ensures that the opening direction of each connector socket 204 is along the height direction of the base 200, which facilitates the opening of slots 302c on each first sidewall 302a and each second sidewall 303b, thereby facilitating the connection of the conductive busbar 400 with the high-voltage connector 100 from different directions.

[0052] Of course, in this embodiment, if necessary, slots 302c can be provided only on each of the second sidewalls 303b or only on each of the first sidewalls 302a, depending on the connection requirements between the conductive busbar 400 and the high-voltage connector 100.

[0053] In addition, continue to combine Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, in some exemplary embodiments, a shield 306 is removably provided on the sidewall in each slot 302c. This ensures high-voltage protection requirements are met, prevents electric shock, and protects personnel safety.

[0054] In practice, the shield 306 can be connected to the side wall via multiple connecting units. Each connecting unit can be disconnected under repeated bending under external force, thus achieving a detachable connection of the shield 306. For this purpose, the protective cover 300 as a whole can preferably be made of plastic to ensure that each connecting unit can be disconnected under repeated bending under external force while meeting insulation requirements.

[0055] It is worth noting that, continuing to combine Figures 1 to 8 As shown, in some exemplary embodiments, the second limiting member 203 of this embodiment can preferably be a second limiting post, and the limiting mating member 304 can be a limiting mating post. The second limiting post and the mating limiting post abut against each other in the height direction of the base 200. At the same time, in order to achieve a better limiting effect on the protective cover 300 in the width direction and the length direction of the base 200, the base 200 of this embodiment is preferably provided with a third limiting member 206 arranged opposite to each of the second limiting members 203 in the width direction of the base 200. The third limiting member 206 can be a third limiting post. In this way, the four inner corner positions of the protective cover 300 can abut against each of the second limiting posts and each of the third limiting posts respectively.

[0056] Furthermore, the first limiting member 202 in this embodiment may include a first limiting post and two baffle plates 2022 disposed on the side of the first limiting post facing the base 200. The two baffle plates 2022 are located on the top of the first limiting post and together with the first limiting post form the aforementioned slot 2021 to engage the high-voltage wire harness. The first limiting member 202 abuts against the limiting mating surface 303 through the top of the first limiting post, the top of each baffle plate 2022, and the limiting mating surface 303. That is, the limiting mating surface 303 conforms to the shape formed by the top of the first limiting post and the top of each baffle plate 2022.

[0057] In addition, continue to combine Figures 4 to 6 ,as well as Figure 9 As shown, in some exemplary embodiments, the base 200 has a guide groove 2041 located on the inner wall of the connector socket 204, and the conductive post 102 has a guide rib 1021 inserted into the guide groove 2041. This arrangement facilitates the assembly and disassembly of the high-voltage connector 100 and the base 200. It should be noted that the guide rib 1021 preferably has an interference fit with the guide groove 2041 to achieve a reliable connection between the high-voltage connector 100 and the base 200.

[0058] Furthermore, continue to combine Figures 1 to 4 ,as well as Figures 9 to 11 As shown, the anti-rotation bracket of the high-voltage connector 100 in this embodiment also includes a mounting plate 600 disposed between the high-voltage connector 100 and the base 200, and a buffer pad 500 disposed between the mounting plate 600 and the base 200. By providing the buffer pad 500, a buffering effect can be achieved, ensuring the installation reliability of the high-voltage connector 100 and the base 200 and the use reliability of the anti-rotation bracket.

[0059] Of course, the mounting plate 600 in this embodiment can be a battery pack frame or a mounting carrier on the battery pack to facilitate the installation of the high voltage connector 100 and the base 200, etc. At the same time, in order to ensure the connection between the high voltage connector 100 and the conductive bar 400, both the mounting plate 600 and the buffer pad 500 are provided with avoidance holes 603 for avoiding each conductive post 102.

[0060] In this embodiment, the mounting plate 600 is preferably provided with a threaded post 602, and the high-voltage connector 100 is provided with a mounting through hole 104. The high-voltage connector 100 can be screwed to the threaded post 602 by a bolt passing through the mounting through hole 104 to achieve a fixed connection between it and the mounting plate 600. Moreover, if necessary, a positioning pin 103 can be provided on the high-voltage connector 100, and a positioning hole 601 can be provided on the mounting plate 600. The positioning pin 103 is inserted into the positioning hole 601 to achieve positioning installation between the high-voltage connector 100 and the mounting plate 600.

[0061] An embodiment of the second aspect of this application provides a battery pack having an anti-rotation bracket for the high-voltage connector 100 as described above.

[0062] The battery in this embodiment, by providing the anti-rotation bracket of the high-voltage connector 100 in the first aspect embodiment, has the same beneficial effect as the conventional technology, and will not be described in detail here.

[0063] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
