Description

Technical Field

[0001] This utility model belongs to the field of high-voltage line fixing, and in particular relates to a high-voltage line harness fixing bracket. Background Technology

[0002] In the assembly of high-voltage wiring harnesses for new energy vehicles, traditional wiring harness brackets generally rely on standard parts such as bolts for fixing, or need to be directly fixed to the vehicle frame. However, there are many special cases in actual assembly scenarios: some high-voltage wiring harnesses do not need to be fixed, or cannot be fixed to the vehicle frame due to space limitations, but it is still necessary to effectively position the wiring harnesses to avoid mutual interference between them, while ensuring the overall aesthetics after assembly.

[0003] In the existing technology, the fixing method of wire harness bracket not only increases the assembly steps and the cost of using standard parts, but also makes it difficult to adjust flexibly according to the number of wire harnesses, and cannot meet the needs of multi-wire harness combination positioning.

[0004] Therefore, there is an urgent need to design a high-voltage wiring harness fixing bracket to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a high-voltage wire harness fixing bracket, which has the advantage of simple installation and solves the problem that existing wire harness brackets all need to use standard parts for fixing.

[0006] To achieve the above objectives, the specific technical solution of the high-voltage wire harness fixing bracket of this utility model is as follows: a high-voltage wire harness fixing bracket, including a first bracket and a second bracket;

[0007] The first bracket includes a first upper ring and a first lower ring, which are fitted together.

[0008] The second bracket includes a second upper ring and a second lower ring, which are fitted together.

[0009] The first lower ring and the second lower ring are interlocked.

[0010] Furthermore, the first upper ring includes a first fixing part, and the first lower ring includes a second fixing part. The first fixing part and the second fixing part are semi-circular, and the first fixing part and the second fixing part are fastened together in a circular shape.

[0011] Furthermore, the first upper ring also includes two first connecting portions, which are respectively fixedly disposed on both sides of the first fixing portion. The first lower ring also includes two second connecting portions, which are respectively fixedly disposed on both sides of the second fixing portion. The lower end of the first connecting portion is provided with a first groove, and the upper end of the second connecting portion is provided with a first boss, which engages with the first groove.

[0012] Furthermore, the second upper ring includes a third fixing part, and the second lower ring includes a fourth fixing part. The third fixing part and the fourth fixing part are semi-circular, and the third fixing part and the fourth fixing part are fastened together to form a circle.

[0013] Furthermore, the second upper ring also includes two third connecting parts, which are respectively fixedly disposed on both sides of the third fixing part. The second lower ring also includes two fourth connecting parts, which are respectively fixedly disposed on both sides of the fourth fixing part. The lower end of the third connecting part is provided with a second groove, and the upper end of the fourth connecting part is provided with a second boss, which engages with the second groove.

[0014] Furthermore, a third boss is provided on the side of the second connecting portion away from the second fixing portion, and a third groove is provided on the side of the fourth connecting portion away from the fourth fixing portion, wherein the third boss and the third groove are fitted together.

[0015] Furthermore, the surfaces of the first boss, the second boss, and the third boss are all coated with an anti-slip coating.

[0016] Furthermore, the surfaces of the first groove, the second groove, and the third groove are all coated with an anti-slip coating.

[0017] Furthermore, the high-voltage harness fixing bracket also includes an inner sleeve, which is engaged between the first upper ring and the first lower ring or between the second upper ring and the second lower ring.

[0018] The high-voltage wire harness fixing bracket of this utility model has the following advantages:

[0019] 1. No standard parts required for installation: This combination bracket is fixed by the interlocking connection of each boss and groove, without the use of standard parts such as bolts, which simplifies the installation process, reduces the requirements for the installation position, facilitates quick operation, and improves assembly efficiency.

[0020] 2. Multiple wire harnesses can be combined: Through the interlocking connection of the first bracket and the second bracket, they can be flexibly combined according to the number of high-voltage wire harnesses to meet the positioning requirements of different numbers of high-voltage wire harnesses.

[0021] 3. Good positioning and protection effect: The fixing parts of the first and second brackets can effectively position the wire harness and prevent interference between the wire harnesses. At the same time, the inner sleeve and the bracket itself can provide a certain degree of protection for the wire harness. Moreover, the anti-slip coating on the surface of each boss and groove increases the stability of the connection and prevents the first or second bracket from falling off due to vibration or other reasons during vehicle movement.
