Description

Technical Field

[0001] This utility model belongs to the field of high-voltage wiring harness fixing technology, specifically relating to a high-voltage wiring harness fixing bracket for new energy vehicles. Background Technology

[0002] High-voltage wiring harnesses, acting as the "blood vessels" of new energy vehicles, connect various high-voltage components to transmit electricity. They are characterized by high voltage, high current, large wire diameter, and large bending radius. The design and layout of high-voltage wiring harnesses are crucial, requiring careful consideration of aesthetics, safety, and durability. The crisscrossing and parallel arrangement of high-voltage and low-voltage wiring harnesses on the vehicle body can cause electromagnetic interference to the low-voltage signals. Furthermore, during vehicle operation, the wiring harnesses sway with the vehicle body, and prolonged swaying can lead to wear and tear on the harnesses and surrounding components, resulting in poor contact, short circuits, and insulation failures. Therefore, a more rational layout of high-voltage wiring harnesses is essential. Utility Model Content

[0003] The purpose of this invention is to propose a fixing bracket for high-voltage wiring harnesses in new energy vehicles to solve the problems of high-voltage wiring harnesses being worn by wind, sand and gravel, being messy in arrangement, and being subject to electromagnetic interference.

[0004] To achieve the above objectives, the specific solution of this utility model is as follows: a high-voltage wiring harness fixing bracket for new energy vehicles, including an arc-shaped wire groove (101), an upper fixing bracket (102) and a lower fixing bracket (103), wherein the upper fixing bracket (102) and the lower fixing bracket (103) are connected at an angle.

[0005] The arc-shaped wire groove (101) is provided with four arc-shaped channels, and the high-voltage wire harness (A) is arranged below the arc-shaped channels. The depth of each arc-shaped channel of the arc-shaped wire groove (101) is adapted to the outer diameter of the high-voltage wire harness (A).

[0006] The arc-shaped groove (101) is provided with triangular ribs (104) at the connection points between its left and right sides and the upper fixed bracket (102) and the lower fixed bracket (103).

[0007] The upper fixed bracket (102) is provided with mounting holes (102-2) on the left and right sides for connecting the vehicle body crossbeam (C). The vehicle body crossbeam (C) is welded to the chassis floor (B). The high-voltage wire harness fixing bracket is fixed to the vehicle body crossbeam (C) by bolts through the mounting holes (102-2).

[0008] The upper fixed bracket (102) and the lower fixed bracket (103) are connected at an angle, which is an obtuse angle.

[0009] The upper fixed bracket (102) is provided with a conformal flange structure (102-1) above it.

[0010] The lower fixed bracket (103) is provided with a conformal flange structure (103-1) below it.

[0011] The beneficial effects of this utility model are as follows: A high-voltage wiring harness fixing bracket for new energy vehicles provides enclosed protection for the high-voltage wiring harness, preventing interference between the high-voltage wiring harness and low-voltage accessories, solving electromagnetic interference problems, and mitigating wear on the wiring harness caused by wind, sand, and gravel. The arc-shaped wire groove restricts the routing of the high-voltage wiring harness, effectively solving the problem of messy high-voltage wiring harness arrangement and making the wiring harness arrangement more aesthetically pleasing and safer.

Detailed Implementation

[0017] like Figure 1 , 2 As shown in Figures 3 and 4, a high-voltage wiring harness fixing bracket for new energy vehicles includes an arc-shaped wire groove (101), an upper fixing bracket (102), and a lower fixing bracket (103). The upper fixing bracket (102) and the lower fixing bracket (103) are connected at an angle, which is an obtuse angle to meet the large bending radius of the high-voltage wiring harness (A) and ensure that the high-voltage wiring harness is not deformed by force.

[0018] like Figure 1 , 2 As shown in Figure 3, the arc-shaped wire groove (101) is provided with four arc-shaped channels. The high-voltage wire harness (A) is arranged below the arc-shaped channels, and the depth of each arc-shaped channel of the arc-shaped wire groove (101) is adapted to the outer diameter of the high-voltage wire harness (A). The arc-shaped channels of the high-voltage wire harness can effectively limit the direction of the high-voltage wire harness at the crossbeam (C) of the vehicle body, making its arrangement aesthetically pleasing, and can also provide relatively enclosed protection for the high-voltage wire harness, reducing electromagnetic interference.

[0019] like Figure 3 As shown, triangular ribs (104) are provided at the connection points between the arc-shaped wire groove (101) and the upper fixed bracket (102) and the lower fixed bracket (103) on the left and right sides to enhance the overall strength of the high-voltage wire harness fixing bracket.

[0020] like Figure 1 , 2 As shown in Figure 3, the upper fixed bracket (102) is provided with mounting holes (102-2) on the left and right sides for connecting the vehicle body crossbeam (C). The vehicle body crossbeam (C) is welded to the chassis floor (B). The high-voltage wire harness fixing bracket is fixed to the vehicle body crossbeam (C) by bolts through the mounting holes (102-2). The high-voltage wire harness (A) is arranged below the high-voltage wire harness fixing bracket, so the high-voltage wire harness is reliably fixed.

[0021] like Figure 1 , 2 As shown in Figure 3, the upper fixed bracket (102) is provided with an upper fixed bracket conformal flange structure (102-1) above it, and the lower fixed bracket (103) is provided with a lower fixed bracket conformal flange structure (103-1) below it. This provides strong support for the high-voltage wire harness fixing bracket to enhance the bracket strength and also provides anti-cut protection for the high-voltage wire harness arranged below the bracket.
