Detailed Description of the Invention

[0018] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0019] The embodiment of the present application discloses a tensile-resistant automotive electronic wire harness. Referring to Figures 1-3 , a tensile-resistant automotive electronic wire harness includes a protective shell 1. Side plates 2 are fixedly connected to the outer walls on both sides of the protective shell 1. A fixed shaft 4 is fixedly connected to the inner walls in the middle opposite to the two side plates 2. A winding cylinder 6 is installed on the outer wall of the fixed shaft 4. A cavity is formed between the winding cylinder 6 and the fixed shaft 4. A plurality of clockwork springs 7 are installed inside the cavity. One end of each clockwork spring 7 is fixedly connected to the inner wall of the winding cylinder 6, and the other end is fixedly connected to the outer wall of the fixed shaft 4. The plurality of clockwork springs 7 are evenly distributed at equal intervals inside the cavity. The wire harness body 8 is wound around the outer wall of the winding cylinder 6.

[0020] On the middle outer walls of the two sides of the protective case 1 that are horizontally perpendicular to the two side plates 2, wire outlet openings 9 are provided. On the outer walls of the two sides of the protective case 1, buffer cylinders 3 are fixedly connected, and the two buffer cylinders 3 correspond to the two wire outlet openings 9 respectively.

[0021] Both ends of the wire harness body 8 pass through the wire outlet openings 9 and penetrate the buffer cylinders 3. On the outer wall of the buffer cylinder 3 close to the wire outlet opening 9 and inside the buffer cylinder 3, a card slot 10 is provided. A movable ring 11 is movably connected to the outer wall of the card slot 10. The movable ring 11 is clamped on the outer wall of the wire harness body 8 through the card slot 10, so that the movable ring 11 is fixed at a certain position on the outer wall of the wire outlet opening 9.

[0022] Buffer springs 12 are installed on the inner walls of the two buffer cylinders 3. One end of the buffer spring 12 is fixedly connected to the outer wall of the movable ring 11, and the other end is fixedly connected to the inner wall of the buffer cylinder 3 on the side away from the protective case 1, and the buffer spring 12 is sleeved on the outer wall of the wire harness body 8.

[0023] Two rotating disks 5 are rotatably connected to the outer wall of the fixed shaft 4. The two rotating disks 5 are respectively fixedly connected to the two ends of the winding cylinder 6. The wire harness body 8 is located between the two rotating disks 5. The two rotating disks 5 are used to limit the wire harness body 8 wound on the winding cylinder 6 to prevent the wire harness body 8 from loosening and disengaging from the winding cylinder 6.

[0024] The implementation principle of a tensile automotive electronic wire harness in an embodiment of the present application is as follows: When tensile forces are applied to both ends of the wire harness body 8, the wire harness body 8 will drive the winding cylinder 6 to rotate. The winding cylinder 6 rotates on the outer wall of the fixed shaft 4 through the two rotating disks 5. Since the winding cylinder 6 is fixed between the two side plates 2, when the winding cylinder 6 rotates, a plurality of clockwork springs 7 are driven to contract, generating elastic potential energy, thereby offsetting the pulling force brought by the external acting force to the wire harness body 8, and the anti-pulling effect is better;

[0025] Moreover, when tensile forces are applied to both ends of the wire harness body 8, the wire harness body 8 drives the two movable rings 11 to slide outward inside the buffer cylinders 3 through the card slots 10 on its outer wall, thereby squeezing the buffer springs 12. The elastic force accumulated by the deformation of the buffer springs 12 can further buffer and offset the external tensile force.
