Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically an automotive wiring harness fixing bracket. Background Technology

[0002] Automotive wiring harnesses are a core component of a vehicle's electrical system, used to connect various electrical devices, sensors, actuators, and control units within the vehicle, transmitting signals and electrical energy. In modern automobiles, wiring harnesses are typically laid out along the vehicle's frame, engine compartment, and chassis to accommodate the layout requirements of different functional modules. Because wiring harnesses are exposed to various factors during vehicle operation, such as vibration, temperature changes, humidity variations, and external impacts, they must be securely fixed in designated positions using appropriate fixing devices to prevent electrical faults caused by loosening, wear, or breakage.

[0003] As the electrification of automobiles continues to increase, the number of wiring harnesses and the complexity of wiring in vehicles are increasing year by year. Wiring harness mounting brackets not only need to meet the basic requirements of reliable fixing, but also need to have the characteristics of versatility, easy assembly, and excellent protection performance. Chinese patent application CN202220551222.2 discloses an automotive wiring harness fixing bracket. The bracket includes a bracket body with a bent structure. A pipe clamp fixing structure is formed at one end of the bend, allowing the bracket body to be fixed to a conduit. A fixing hole is provided at the other end of the bend, through which the bracket body is fixed to the gearbox. An anti-rotation structure is also formed at the other end of the bend, used to clamp onto the gearbox, thereby restricting movement at the other end of the bracket body. While this technical solution effectively utilizes the limited space of the wiring harness arrangement by fixing it to the conduit with a pipe clamp, reducing interference between the wiring harness and other components, reducing assembly points and assembly time, and achieving versatility, it offers limited constraint on the conduit. After being secured with cable ties, the wiring harness is prone to movement and wear, affecting its service life. Therefore, this application proposes an automotive wiring harness fixing bracket to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Combination Figures 1 to 3 This embodiment provides an automotive wiring harness fixing bracket, which includes an L-shaped bracket 1. A wiring harness bracket 2 is welded to the short side of the L-shaped bracket 1. A wiring harness fixing frame is detachably installed on the wiring harness bracket 2. The wiring harness fixing frame is used to bind and fix the wiring harness. Specifically, the wiring harness fixing frame includes an arc-shaped plate 3. The diameter of the arc-shaped plate 3 is consistent with the outer diameter of the wiring harness to be fixed. The inner side of the arc-shaped plate 3 is provided with protective texture 4. The protective texture 4 is a raised fine texture. There are multiple protective textures 4, which are arranged axially along the inner wall of the arc-shaped plate 3. The outer side of the arc-shaped plate 3 is provided with limiting arc strips 5 at both ends. The wiring harness is arranged axially along the arc-shaped plate 3 and fixed circumferentially along the arc-shaped plate 3 by cable ties. There is at least one limiting arc strip 5. In this example, there are two limiting arc strips 5 at each end of the arc-shaped plate 3. After the wiring harness is bound with cable ties, the cable ties are between the two limiting arc strips 5 to prevent the cable ties from slipping off the arc-shaped plate 3.

[0020] Furthermore, the L-shaped bracket 1 has a mounting hole 6 at the end away from the wire harness bracket 2. The mounting hole 6 is located at the long side end of the L-shaped bracket 1. The L-shaped bracket 1 is fixed to the car interior bracket through the mounting hole 6. The bolt passes through the mounting hole 6 and is fixedly connected to the car interior bracket. An anti-rotation structure 7 is provided on one side of the L-shaped bracket 1. After the L-shaped bracket 1 is fixed to the car interior bracket, the anti-rotation structure 7 is in low contact with the car interior bracket to prevent the L-shaped bracket 1 from rotating.

[0021] Furthermore, the wire harness bracket 2 is L-shaped, and two L-shaped reinforcing ribs 8 are provided on the inner side of the wire harness bracket 2. The reinforcing ribs 8 are integrally set with the wire harness bracket 2. The wire harness bracket 2 has a hole 9 between the two reinforcing ribs 8 to improve the strength of the wire harness bracket 2. When the wire harness fixing bracket is not used, the reinforcing ribs 8 can limit the wire harness and fix the wire harness by passing the strap through the hole 9.

[0022] Furthermore, the wire harness fixing bracket also includes a rectangular frame 10, with an arc plate 3 welded onto the rectangular frame 10. The rectangular frame 10 is fitted onto the outside of the wire harness bracket 2, and a locking bolt 11 is threaded onto the rectangular frame 10. The locking bolt 11 extends into the hole 9, and the hole 9 limits the locking bolt 11. The hole 9 is square, and the diameter of the screw of the locking bolt 11 is the same as the side length of the hole 9. Of course, the hole can also be set as a threaded round hole. The locking bolt 11 can limit and fix the rectangular frame 10.

[0023] Furthermore, the inner wall of the rectangular frame 10 is provided with a limiting groove 12 that matches the reinforcing rib 8. The limiting groove 12 can limit the width of the rectangular frame 10. Both ends of the arc plate 3 extend out of the rectangular frame 10. The outer side of the arc plate 3 is welded and fixed to the rectangular frame 10 through the irregular plate 13 for fixing the arc plate 3. The limiting arc strip 5 is provided at the part of the arc plate 3 that extends out of the rectangular frame 10.

[0024] The working principle of this utility model is as follows: the L-shaped bracket 1 is fixed to the internal bracket of the car by bolts, and then the wire harness is arranged along the axial direction of the arc plate 3. The wire harness is tied and fixed to the arc plate 3 by cable ties. The number of L-shaped brackets 1 is arranged according to the length of the wire harness, which can effectively constrain the wire harness, prevent the wire harness from shaking, prevent the outer surface of the wire harness from being worn, and improve the service life of the wire harness. The overall structure is simple, the wire harness is firmly fixed, and the wire harness can be reasonably arranged in the car, saving the space occupied by the wire harness.
