[0002] The overall structure of a car now consists of two parts, one is the mechanical part and the other is the circuit part. The circuit part requires many wires to transmit power signals and control signals. The firmness and reliability of the wiring harness installation are directly related to the safety of the car. Therefore, a wiring harness fixing bracket is required to fix the wiring harness to the frame.

[0003] The existing wire harness fixing bracket currently has a single function and cannot adjust the size of the fixing bracket according to the thickness of the wire harness. Therefore, it is impossible to uniformly fix wire harnesses of various sizes, resulting in the need to use fixing brackets of various sizes when fixing multiple wire harnesses, which takes up a lot of interior space of the car.

[0029] Reference Figure 1-3 A fixing mechanism for an automobile wiring harness is used for fixing the automobile wiring harness in order to uniformly fix wiring harnesses of different sizes and to firmly fix wiring harnesses of different sizes at the same time.

[0030] The fixing mechanism of the automobile wiring harness comprises a base 2, a flip cover 4 and a plurality of fixing components;

[0031] The base 2 is fixed on the mounting frame 1, and a fixing hole is provided on the mounting frame 1 to fix the mounting frame 1 to the vehicle frame, so as to facilitate fixing the fixing mechanism to the vehicle frame. A reinforcing rib is provided on the flip cover 4 to improve the structural strength of the flip cover 4. A plurality of fixing grooves 7 are provided on the side where the flip cover 4 and the base 2 are close to each other. The plurality of fixing grooves 7 are arranged at intervals, and the fixing grooves 7 on the base 2 correspond to the fixing grooves 7 on the flip cover 4 one by one. A rotating shaft 3 is provided on one side of the base 2, and the middle part of the rotating shaft 3 is connected to one side of the flip cover 4, so that the flip cover 4 can be rotated through the rotating shaft 3, so that it can be rotated open and separated from the base 2, so that the wiring harness can be placed in the fixing groove 7 for fixing, and because the fixing grooves 7 on the base 2 correspond to the fixing grooves 7 on the flip cover 4 one by one, the flip cover 4 can be rotated to close. After closing, each fixing groove 7 on the base 2 is combined with a corresponding fixing groove 7 on the flip cover 4 to form a through hole, and the wiring harness is fixed inside the through hole. A fixing seat 201 is provided on the side of the base 2 away from the rotating shaft 3, and a fixing plate 5 is provided on the side of the flip cover 4 away from the rotating shaft 3. The fixing seat 201 and the fixing plate 5 are both provided with openings, and fixing bolts 6 are provided in the openings. When the flip cover 4 is rotated and closed, the fixing plate 5 can be fixed to the fixing seat 201 by the fixing bolts 6, so that the flip cover 4 and the base 2 are fixed, and the wiring harness is fixed in the fixing groove 7, and both ends of each fixing groove 7 are fixedly connected with a half rubber sleeve 8. After the flip cover 4 is rotated and closed, the half rubber sleeve 8 will close to form a complete rubber sleeve, thereby wrapping and protecting the wiring harness in the fixing groove 7 to prevent the wiring harness from being bent and damaged at the end of the fixing groove 7.

[0032] The fixing groove 7 is semicircular, and a plurality of slots 701 are arranged at intervals along the axis on the inner wall of each fixing groove 7, and each slot 701 is in an arc shape. Each fixing component is arranged in a fixing groove 7, and each fixing component includes two card blocks 9 and three elastic sheets 10, each card block 9 is in an arc shape, and the card block 9 is adapted to the card slot 701 so that each card block 9 is embedded in a card slot 701, and the two ends of each elastic sheet 10 are respectively fixedly connected to the two card blocks 9, and each elastic sheet 10 is arranged at intervals around the axis of the fixing groove 7. By changing the distance between the two card blocks 9, the bending curvature of the elastic sheet 10 can be changed. Therefore, when the fixing groove 7 needs to fix a small-sized wiring harness, the distance between the two card blocks 9 is reduced, and then the two card blocks 9 with reduced distances are respectively inserted into the corresponding card slots 701. As the distance between the two clamping blocks 9 is reduced, the bending curvature of the elastic sheet 10 becomes larger, so that the middle part of the elastic sheet 10 can be closer to the axis of the fixing groove 7, so that the small-sized wire harness can be clamped and fixed by the middle arc-shaped part of the multiple arc-shaped elastic sheets 10. When the large-sized wire harness is fixed, the distance between the two clamping blocks 9 is increased, so that the bending curvature of the elastic sheet 10 can be reduced, and the middle part of the elastic sheet 10 is away from the axis of the fixing groove 7, so as to facilitate the fixation of the large-sized wire harness. In addition, since a rubber layer is provided on one side of the elastic sheet 10, a plurality of rubber protrusions 11 are arranged on the rubber layer at intervals along the length direction of the elastic sheet 10. When the elastic sheet 10 clamps and fixes the wire harness, the rubber protrusions 11 will be close to the outer wall of the wire harness, thereby improving the stability of the wire harness fixation.

[0033] The working principle of the fixing mechanism of the automobile wiring harness is as follows: the fixing mechanism of the automobile wiring harness is installed on the vehicle frame through the fixing holes on the mounting frame 1;

[0034] Then, the distance between the two clamping blocks 9 is adjusted according to the size of the wiring harness. When a small-sized wiring harness needs to be fixed, the distance between the two clamping blocks 9 is reduced, and then the two clamping blocks 9 with reduced distance are respectively inserted into the corresponding clamping slots 701. Since the distance between the two clamping blocks 9 is reduced, the bending curvature of the elastic sheet 10 becomes larger, so that the middle part of the elastic sheet 10 can be closer to the central axis of the fixing slot 7, which is equivalent to reducing the inner diameter of the fixing slot 7, so that the small-sized wiring harness can be clamped and fixed by the elastic sheet 10. When a large-sized wiring harness needs to be fixed, the distance between the two clamping blocks 9 is increased. Since the distance between the two clamping blocks 9 is increased, the bending curvature of the elastic sheet 10 is reduced, so that the middle part of the elastic sheet 10 can be moved away from the central axis of the fixing slot 7, which is equivalent to expanding the inner diameter of the fixing slot 7, so that the large-sized wiring harness can be clamped and fixed by the elastic sheet 10.

[0035] Finally, the flip cover 4 is rotated by the rotating shaft 3, so that the flip cover 4 can be rotated open and separated from the base 2, so that the wire harness can be placed in the fixing groove 7, and then the flip cover 4 is rotated closed to fit the base 2. Since the fixing groove 7 on the base 2 corresponds to the fixing groove 7 on the flip cover 4 one by one, after the flip cover 4 is rotated closed, each fixing groove 7 on the base 2 is combined with a corresponding fixing groove 7 on the flip cover 4 to form a through hole, and multiple adjusted arc-shaped elastic sheets 10 in the fixing groove 7 clamp and fix the wire harness through the arc-shaped part in the middle of the elastic sheet 10, so that wire harnesses of different sizes are firmly fixed in the fixing mechanism of the automotive wire harness.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
