[0002] Today's cars integrate a vast array of electronic devices and control systems, such as engine management systems, in-car entertainment systems, and airbag systems. These systems transmit power and signals through complex wiring harnesses. To ensure the proper functioning of these electrical systems, wiring harnesses must remain securely fixed while the car is in motion, preventing problems such as disconnection, short circuits, and signal interference caused by shaking or shifting.

[0003] Traditional automotive wiring harness securing methods have numerous drawbacks. Simple binding methods or clip-on securing methods are unable to withstand the vibration, jolts, and twisting and deformation of the vehicle during long-term operation, easily causing the wiring harness to loosen and shift, thereby affecting the stability of the electrical system. Furthermore, traditional securing methods lack effective protection for the wiring harness, making it susceptible to friction with other vehicle body components, leading to wear and tear on the outer covering and increasing electrical safety hazards. Furthermore, traditional wiring methods often result in a cluttered wiring harness layout, making it difficult to quickly locate and handle the wiring harness during installation during production or subsequent maintenance.

[0030] See also Figure 1-4 , the utility model provides a technical solution:

[0031] A fixing structure for an automobile wiring harness includes a suction cup 1 and an extrusion block 7. The suction cup 1 is internally threaded with a bolt 2, and the upper side of the outer surface of the bolt 2 is threadedly connected to a fixing box 3. The front and rear ends of the fixing box 3 are both provided with a plurality of wiring holes 4. A sponge pad 5 is provided on the lower inner wall surface of the fixing box 3 and in the plurality of wiring holes 4. The front and rear inner wall surfaces of the fixing box 3 are both provided with a plurality of movable grooves 6. The front and rear ends of the extrusion block 7 are fixedly connected with a plurality of movable plates 8. The lower end of the extrusion block 7 is fixedly connected with a plurality of clamping blocks 9. The rear end of the fixing box 3 is connected with an L-shaped connecting plate 10 by two screws. The upper end of the L-shaped connecting plate 10 is provided with a threaded hole 11 passing through the upper and lower ends. A screw 12 is threadedly connected to the inner surface of the threaded hole 11, and the upper end of the screw 12 is fixedly connected with a rotating block 13.

[0032] Through the above scheme, bolt 2 is first threaded into suction cup 1, providing a stable foundation for subsequent components. Next, fixing box 3 is threaded onto the upper surface of bolt 2 to secure it in place. Several equally spaced wiring holes 4 are provided at the front and rear ends of fixing box 3 to facilitate the passage of the wiring harness. The front and rear inner walls of fixing box 3 feature several movable slots 6, and movable plates 8 at the front and rear ends of extrusion block 7 are flexibly connected to them. The lower end of screw 12 is flexibly connected to the upper end of extrusion block 7 via a bearing. A rotating block 13 at its upper end facilitates operation, allowing the vehicle wiring harness to be sequentially threaded through the wiring holes 4 and placed into fixing box 3. Rotating rotating block 13 rotates screw 12, causing extrusion block 7 to move within the movable slots 6 via movable plates 8. The clamping block 9 at its lower end cooperates with fixing box 3 to clamp the wiring harness. During this process, the sponge padding 5 on the wiring holes 4 and the lower inner wall of fixing box 3 provides cushioning and protection. An L-shaped connecting plate 10 is tightly connected to the rear end of fixing box 3 via two screws. The screw 12 in threaded hole 11 and other components work together to ensure the stability and reliability of the entire fixing structure.

[0033] In this embodiment, the extrusion block 7 is movably connected to several movable plates 8 fixedly connected at its front and rear ends with several movable grooves 6 opened on the front inner wall and rear inner wall of the fixed box 3; several clamping blocks 9 are integrally connected to the lower end of the suction cup 1, and several clamping blocks 9 are arc-shaped structures, and rubber anti-slip pads are provided on their inner sides; the L-shaped connecting plate 10 is tightly connected to the rear end of the suction cup 1 by two screws, and the heads of the screws are flush with the surface of the L-shaped connecting plate 10; the rotating block 13 is integrally connected to the upper end of the screw 12; the lower end of the screw 12 is movably connected to the upper end of the extrusion block 7 through a bearing; several wiring holes 4 pass through the front and rear ends of the fixed box 3, and the distance between two adjacent wiring holes 4 is equal.

[0034] According to the above scheme: the several movable plates 8 at the front and rear ends of the extrusion block 7 are movably connected to the movable grooves 6 on the front and rear inner walls of the fixing box 3. When the position of the extrusion block 7 needs to be adjusted, the movable plates 8 can slide in the movable grooves 6, thereby driving the extrusion block 7 to move up and down to adapt to the needs of fixing wire harnesses of different diameters or quantities; several clamping blocks 9 are integrally formed with the lower end of the suction cup 1, and have an arc-shaped structure and a rubber anti-skid pad on the inside. When fixing the wire harness, the clamping blocks 9 can fit around the wire harness, and with the help of the friction of the rubber anti-skid pad, the wire harness is further stabilized to prevent it from slipping off the suction cup 1; the L-shaped connecting plate 10 is tightly connected to the rear end of the suction cup 1 by two screws, and the screw heads are flush with the surface of the L-shaped connecting plate 10. This connection method is both firm and ensures the flatness of the connection part, providing stable support for the installation of subsequent components; the rotating block 13 is integrally formed with the upper end of the screw 12. Rotating the rotating block 13 directly drives the screw 12 to rotate synchronously, enabling adjustments to the positions of components associated with the screw 12. The lower end of the screw 12 is movably connected to the upper end of the extrusion block 7 via a bearing. As the screw 12 rotates, the bearing allows the extrusion block 7 to smoothly adjust its position up and down, precisely controlling the spacing between the extrusion block 7 and the fixed box 3, thereby effectively clamping the wiring harness. Several wiring holes 4 are evenly spaced throughout the front and rear ends of the fixed box 3. This allows the wiring harness to follow a standardized path through the fixed box 3, facilitating the organization of the wiring harness layout and enabling quick location and handling of specific wiring harnesses during installation and subsequent maintenance.

[0035] It should be noted that this utility model is a mounting structure for an automotive wiring harness. During use, first, select an appropriate mounting surface based on the desired mounting location within the vehicle. If using a suction cup 1, press it into place, preparing the lower clamping block 9 and inner rubber non-slip pad. Screw the bolt 2 into the suction cup 1, then install the mounting box 3 and secure it securely. Check the wiring holes 4 at the front and rear ends of the mounting box 3 and the internal sponge pad 5 to ensure smooth access and protection. Grip the rotating block 13 and rotate it. Since it is integrally formed with the upper end of the screw 12, rotating it will drive the screw 12 in its turn. The lower end of the screw 12 is movably connected to the extrusion block 7, which is connected to the movable groove 6 of the fixed box 3 via the movable plate 8. Rotating the screw 12 allows the extrusion block 7 to move up and down within the movable groove 6. Adjusting the position to clamp the wiring harness, the vehicle wiring harness is sequentially passed through the wiring holes 4 and placed below the extrusion block 7 in the fixed box 3. The rotating block 13 is then rotated to move the extrusion block 7 downward. The clamping block 9 and the fixed box 3 jointly clamp the wiring harness. During this process, the sponge pad 5 acts as a buffer and protection. Regular inspections are conducted while the vehicle is running to check the suction cup 1, component connections, and wiring harness status. Any problems should be addressed promptly. During maintenance, the standardized wiring holes 4 and fixed box 3 facilitate quick location and handling of wiring harness-related issues.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
