Technical Field

[0001] The utility model relates to the technical field of battery packs, and in particular to an anti-rotation bracket. Meanwhile, the utility model also relates to a battery pack provided with the anti-rotation bracket. Background Art

[0002] In new energy vehicles, the high-voltage connector is the interface for power transmission inside and outside the battery pack. The high-voltage connector is connected to the copper bus inside the battery pack, and the stability of its connection directly affects the quality of power transmission and even the safety of the battery pack.

[0003] The high-voltage connector is divided into a connector part and a wiring harness part. The installation and fixation of the wiring harness part is a problem that needs to be solved. The anti-rotation bracket is installed between the high-voltage connector and the copper busbar. It can not only achieve the protection requirements of the electrical clearance and creepage distance, but also prevent the copper busbar from rotating during the installation process, thereby achieving a reliable connection between the copper busbar and the high-voltage connector.

[0004] However, the existing anti-rotation brackets have high requirements on the space for installation operations, while the space inside the battery pack is usually relatively compact. This makes many anti-rotation brackets difficult to operate during actual installation and cannot meet the overall development and design requirements of the battery pack. Utility Model Content

[0005] In view of this, the utility model aims to provide an anti-rotation bracket, which has good disassembly and assembly convenience.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] An anti-rotation bracket comprises a base provided with connector sockets arranged in a front-to-back direction, and an upper cover provided on the base, wherein the base can be plugged with a high-voltage connector through the connector sockets;

[0008] The base is provided with a rotating shaft and a clamping column arranged at intervals in the front-to-back direction, the rotating shaft is arranged close to the high-voltage connector, and the clamping column is arranged at intervals behind the rotating shaft;

[0009] The upper cover is provided with a snap-in groove corresponding to the rotating shaft, and a snap-in hook corresponding to the snap-in groove on the snap-in column, and the upper cover can be snap-into the rotating shaft through the snap-in groove, rotatably arranged on the base, and can be snapped into the snap-in groove through the snap-in hook to be snap-into and fixed with the base.

[0010] Furthermore, a plurality of copper busbar sockets are provided on the side wall of the base, each of the copper busbar sockets has a different plugging direction, and each of the copper busbar sockets is provided for the copper busbar connected to the high-voltage connector to pass through.

[0011] Furthermore, the upper cover is provided with a shielding plate for blocking at least one of the copper busbar sockets.

[0012] Furthermore, the shielding plate is connected to the upper cover via a breakable brittle connector.

[0013] Furthermore, the base is provided with a support wall extending in the front-to-back direction, and the support wall is provided with a harness groove for placing the interlocking wire.

[0014] Furthermore, a harness matching groove is provided at the bottom of the upper cover; when the upper cover is snap-fitted with the base, the support wall abuts against the harness matching groove to limit the interlocking wire in the harness groove.

[0015] Furthermore, the base is provided with a limiting groove corresponding to the connector socket, and the limiting groove is used to limit the plug-in end of the high-voltage connector from moving forward along the front-to-back direction.

[0016] Furthermore, the limiting grooves are two respectively arranged on the left and right sides of the supporting wall; and / or the copper busbar is connected to the plug-in end by bolts.

[0017] Furthermore, the upper cover is provided with an avoidance groove, and the avoidance groove is used to avoid the bolts fixing the copper busbar.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The anti-rotation bracket described in the utility model can realize the rotation of the upper cover relative to the base through the cooperation of the rotating shaft and the clamping groove, and can realize the clamping connection between the upper cover and the base in a smaller operating space through the cooperation of the clamping hook and the clamping column, and the operation is simple, which is conducive to improving the convenience of disassembly and assembly of the anti-rotation bracket.

[0020] In addition, multiple copper busbar sockets with different plug-in directions are provided to provide multiple copper busbar installation points, making the anti-rotation bracket suitable for connection schemes of copper busbars with different insertion directions. The shielding plate is connected to the upper cover through a breakable brittle connector. When necessary, the protective sheet in the direction of inserting the copper busbar can be broken off, and the remaining directions are retained. This can not only meet the multi-directional installation of the copper busbar, making the application scenario more flexible, but also prevent fingers from contacting the high-voltage connector or the exposed part of the copper busbar, meeting the safety protection requirements.

[0021] In addition, the setting of the harness groove is conducive to the arrangement and placement of the interlocking wires. At the same time, after cooperating with the harness matching groove, the interlocking wires can be effectively limited to prevent the interlocking wires from rubbing against the surrounding parts and being damaged. The support wall also divides the positive and negative poles of the high-voltage connector into two spaces on the left and right, effectively ensuring the protection requirements of the electrical clearance and creepage distance. The setting of the limit groove can effectively prevent the high-voltage connector from detaching from the anti-rotation bracket and increase the structural stability.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] Embodiment 1

[0040] The present embodiment relates to an anti-rotation bracket, which not only has good structural stability, but also can realize convenient disassembly between the upper cover 2 and the base 1 in a small operating space.

[0041] In terms of overall structure, Figures 1 to 7As shown, the anti-rotation bracket of this embodiment includes a base 1 provided with connector sockets 11 arranged along the front-to-back direction, and an upper cover 2 arranged on the base 1, and the base 1 can be plugged with the high-voltage connector through the connector sockets 11.

[0042] In addition, the base 1 is provided with a rotating shaft 12 and a clamping column 13 which are arranged at intervals in the front-to-back direction. The rotating shaft 12 is arranged close to the high-voltage connector, and the clamping column 13 is arranged at intervals behind the rotating shaft.

[0043] The upper cover 2 is provided with a snap-in groove 211 corresponding to the rotating shaft 12 and a hook 22 corresponding to the slot 131 on the snap-in column 13. The upper cover 2 can be snap-into the rotating shaft 12 through the snap-in groove 211, rotatably disposed on the base 1, and can be snap-into the slot 131 through the hook 22 to be snap-into and fixed with the base 1.

[0044] In specific implementation, the base 1 of this embodiment includes a plug-in part provided with a connector socket 11, and a fixed part located behind the plug-in part. The rotating shaft 12 and the clamping column 13 are preferably arranged at the top of the base 1, and the rotating shaft 12 is preferably arranged at the rear side of the plug-in part, and the clamping column 13 is preferably arranged at the rear top of the fixed part (that is, the base 1) to facilitate clamping with the upper cover 2.

[0045] At the same time, the front side of the upper cover 2 of the present embodiment is preferably provided with a rotating arm 21 extending forward, a snap-in groove 211 is formed on the rotating arm 21, and a hook 22 is provided on the rear side of the upper cover 2, so as to facilitate the rationality of the structural design and realize that after one end of the upper cover 2 is rotated and snap-connected with the base 1, the other end is snap-connected and fixed with the base 1.

[0046] If necessary, a plug-in structure may be provided between the base 1 and the high-voltage connector to ensure that the high-voltage connector and the base 1 will not rotate in a direction perpendicular to the front-to-back direction. For example, a plug-in column located in the connector socket 11 may be provided on the base 1, and a plug-in hole corresponding to the plug-in column may be provided on the high-voltage connector.

[0047] Furthermore, the related structural parts not mentioned in the anti-rotation bracket of this embodiment can refer to the various structures of the anti-rotation bracket well known to those skilled in the art, such as the reinforcement ribs provided on the side wall of the base 1, and will not be described in detail here.

[0048] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, see Figure 3 and Figure 4 As shown, a plurality of copper busbar sockets 10 are provided on the side wall of the base 1, each copper busbar socket 10 has a different plugging direction, and each copper busbar socket 10 is provided for passing a copper busbar connected to a high-voltage connector.

[0049] By providing a plurality of copper busbar sockets 10 with different plugging directions, a plurality of copper busbar installation points can be provided, so that the anti-rotation bracket is suitable for connection schemes of copper busbars with different insertion directions.

[0050] Moreover, in the specific implementation, a mounting groove connected to the copper busbar socket 10 is provided on the base 1, and the mounting groove is correspondingly connected to the connector socket 11, and the bottom of the copper busbar socket 10 is flush with the top of the part of the high-voltage connector inserted into the mounting groove, so as to facilitate the stable connection between the copper busbar and the high-voltage connector.

[0051] It is worth mentioning that the connector socket 11 of the present embodiment is preferably composed of two connected circular holes, so that it is convenient to insert the high-voltage connector into the plug-in part, and it is also possible to prevent the high-voltage connector from rotating relative to the base 1. The high-voltage connector usually has two plug-in ends, and the two plug-in ends correspond to the two circular holes one by one. There are also two mounting grooves arranged at intervals on the left and right to correspond to each circular hole one by one. At the same time, one mounting groove can correspond to one or more copper busbar sockets 10. Specifically in the present embodiment, the mounting groove on the left corresponds to and connects the left copper sheet socket 10 and the copper sheet socket 10 on the left rear part of the base 1, and the mounting groove on the right corresponds to and connects the right copper busbar socket 10 and the copper busbar socket 10 on the right rear part of the base 1.

[0052] Secondly, the location and number of the copper busbar sockets 10 of this embodiment can be set and adjusted accordingly according to the insertion requirements of the copper busbar. For example, a copper busbar socket 10 is provided on each side of the base 1, and two copper busbar sockets 10 are arranged in sequence along the left and right directions at the rear of the base 1.

[0053] It should still be noted that the above-mentioned copper busbar sockets 10 and mounting grooves are both located in the fixed part of the base 1, and the top of the fixed part is open to facilitate the installation and arrangement of the copper busbar. When the upper cover 2 is placed on the base 1, the top opening of the fixed part is sealed, leaving only the copper busbar sockets 10 and the copper busbars confined in each copper busbar socket 10.

[0054] See also Figure 1 and Figure 2 As shown, in this embodiment, as a preferred implementation form, a shielding plate 23 for blocking at least one copper busbar socket 10 is provided on the upper cover 2. In specific implementation, a shielding plate 23 is provided on the upper cover 2 corresponding to the position where the copper busbar socket 10 does not need to be inserted, thereby preventing fingers from contacting the exposed part of the high-voltage connector or the copper busbar, thereby improving safety.

[0055] And, combined with Figure 6 and Figure 7As shown, in this embodiment, as a preferred implementation form, the shielding plate 23 is connected to the upper cover 2 through a breakable brittle connection member 24. In specific implementation, the brittle connection member 24 can be formed by a connection member with a smaller cross-sectional area to facilitate the breaking operation. At the same time, the upper cover 2 can be made of plastic material as a whole to further ensure the convenience of breaking.

[0056] It can be understood that the baffle plate 23 is connected to the upper cover 2 through a breakable brittle connector 24. The protective plate in the direction of inserting the copper busbar can be broken off when necessary, and the other directions can be retained. For example, in this embodiment, the baffle plates 23 on the left and right sides of the base 1 can be broken off, and the baffle plates 23 on the left and right sides of the rear part of the base 1 can be retained, so that the positive and negative copper busbars of the battery pack can enter the installation grooves on the left and right sides from the left and right sides respectively to be connected to the corresponding plug-in ends of the high-voltage connector.

[0057] In this way, the copper busbar can be installed in multiple directions, making the application scenarios more flexible, and at the same time, it can prevent fingers from touching the high-voltage connector or the exposed part of the copper busbar, meeting the safety protection requirements.

[0058] In addition, in this embodiment, as a preferred implementation form, see Figures 2 to 4 As shown, the base 1 is provided with a support wall 14 extending in the front-to-back direction, and the support wall 14 is provided with a harness groove 141 for placing the interlocking wires. The harness groove 141 is arranged along the extension direction of the support wall 14 to facilitate the placement of the interlocking wires.

[0059] Specifically, the support wall 14 of this embodiment is located in the middle of the two mounting grooves, or in other words, the two mounting grooves are separated by the support wall 14. Secondly, in this embodiment, as a preferred implementation form, a harness matching groove 251 is provided at the bottom of the upper cover 2. When the upper cover 2 is clamped with the base 1, the support wall 14 abuts against the harness matching groove 251 to limit the interlocking wire in the harness groove 141.

[0060] The advantage of such a setting is that after the wiring harness groove 141 and the wiring harness matching groove 251 are matched, the interlocking wire can be effectively limited to prevent the interlocking wire from being damaged by friction with surrounding parts, and the support wall 14 also divides the positive and negative poles of the high-voltage connector into two left and right spaces, effectively ensuring the protection requirements of electrical clearance and creepage distance.

[0061] In detail, the bottom of the upper cover 2 of the present embodiment is provided with a partition 25 assembly arranged at intervals along the left-right direction, and each partition 25 assembly includes two partitions 25 arranged at intervals along the front-back direction. During specific implementation, the left and right sides of the support wall 14 are respectively abutted and matched with the partitions 25 on the corresponding sides to form a closure for the wiring harness groove 141, which is not only conducive to weight reduction, but also can form a wiring harness matching groove 251 through the two partition 25 assemblies.

[0062] At the same time, in this embodiment, as a preferred implementation form, see Figure 4 and Figure 5 As shown, the base 1 is provided with a limiting groove 151 corresponding to the connector socket 11, and the limiting groove 151 is used to limit the plug-in end of the high-voltage connector from moving forward along the front-to-back direction.

[0063] Such a configuration can effectively prevent the high-voltage connector from being separated from the anti-rotation bracket, thereby increasing the structural stability. In a specific implementation, two limiting walls 15 are arranged at intervals along the left-right direction in each installation slot, and the two limiting walls 15 are both extended along the front-back direction, and the limiting slot 151 is formed between the two limiting walls 15.

[0064] Furthermore, based on the requirement that the limit groove 151 limits the forward movement of the plug-in end, the two limit walls 15 can be gradually arranged closer from back to front to form a small spacing portion in the limit groove 151. In this way, after the plug-in end and the copper busbar are installed, the limited plug-in end can be separated from the installation groove to damage the copper sheet and the interlocking wire.

[0065] Of course, based on the structural design of the above-mentioned limit groove 151, the high-voltage connector can be inserted along the connector socket 11 during installation until the raised part of the plug-in end passes over the small spacing part at the front end of the limit groove 151, and is plugged and fixed with the base 1.

[0066] In the specific implementation, in this embodiment, as a preferred implementation form, there are two limit grooves 151 respectively arranged on the left and right sides of the support wall 14, that is, as mentioned above, there are two limit walls 15 in each installation groove, and each limit groove 151 is formed between the two limit walls 15 in the corresponding installation groove. There are also two connector sockets 11 and two plug-in terminals. After plugging and fixing, each plug-in terminal is respectively limited in the corresponding limit groove 151, which is beneficial to improving the plug-in reliability between the high-voltage connector and the base 1.

[0067] Likewise, as a preferred implementation form, the copper busbar is connected to the plug-in end by bolts to ensure the connection strength between the two.

[0068] In addition, in this embodiment, as a preferred implementation form, see Figure 7 As shown, the upper cover 2 is provided with an escape groove 26, which is used to escape the bolts fixing the copper bar. The advantage of such a setting is that the stability of the clamping connection between the upper cover 2 and the base 1 can be avoided to be affected by the bolts.

[0069] The anti-rotation bracket of the present embodiment can realize the rotation of the upper cover 2 relative to the base 1 through the cooperation of the rotating shaft 12 and the snap-in groove 211, and can realize the snap connection between the upper cover 2 and the base 1 in a smaller operating space through the cooperation of the snap-in hook 22 and the snap-in column 13, and the operation is simple, which is conducive to improving the convenience of disassembly and assembly of the anti-rotation bracket.

[0070] Embodiment 2

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
