Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 3, the utility model provides an embodiment: an anti-interference integrated wiring harness for an electric control system of an autonomous vehicle, comprising an insulating coat 1 and a sliding square block 8. The insulating coat 1 exists to protect the internal wires and connectors from damage by the external environment, such as moisture, dust, chemicals, etc. It ensures that the wire system can operate normally under various conditions and is safe and harmless to vehicle passengers and the surrounding environment. The sliding square block 8 is provided with a plurality of holes 2. The inner wall of the insulating coat 1 is fixedly connected with a flame retardant layer 2. The main function of the flame retardant layer 2 is to prevent the spread of flames and slow down the burning speed of the wiring harness when encountering a fire or high temperature, thereby increasing the safety of the vehicle. This is a vital layer of protection in the electric control system of an autonomous vehicle to ensure that the vehicle can still maintain its function under extreme conditions. The inner wall of the flame retardant layer 2 is fixedly connected with a reinforcement layer 3. The function of the reinforcement layer 3 is to enhance the structural stability and durability of the wiring harness to prevent the wiring harness from being damaged by vibration, stretching or external impact during use. This reinforcement can ensure that the wiring harness always maintains its shape and function during the operation of the vehicle. The inner wall of the reinforcement layer 3 is fixedly connected with multiple separation components, and the separation components include a fixing ring 4. The outer part of the fixing ring 4 is fixedly connected to the inner wall of the reinforcement layer 3. The outer part of multiple wires 5 is fixedly connected to the inner hole of the fixing ring 4. The main function is to separate the wires 5 to prevent them from interfering with or damaging each other. Through the design of the fixing ring 4 and the hole, the wires 5 can be arranged in an orderly manner, which not only ensures the neatness of the wiring harness, but also helps to reduce the influence of electromagnetic interference, thereby improving the stability and performance of the system. The interior of the separation component is slidably connected with multiple wires 5. The interior of the insulating outer coat 1 is provided with anti-stretching metal ring pieces 6. The function of these metal ring pieces is to provide additional support and protection when the wiring harness is subjected to tensile force to prevent the wiring harness from breaking or being damaged. They are installed between the insulating outer coat 1 and the reinforcement layer 3 to enhance the structural strength of the entire wiring harness. The interior of the reinforcement layer 3 is provided with anti-interference metal ring pieces 7. The main function of these metal ring pieces is to provide shielding protection when the wiring harness is subjected to electromagnetic interference to ensure the stability and reliability of signal transmission. They are installed inside the reinforcement layer 3 to prevent external electromagnetic interference from affecting the wiring harness.

[0023] Reference Figure 1 and Figure 2The sliding square block 8 is fixedly connected with a plurality of sliding rods 9 inside, and the sliding rod 9 is slidably connected with a sleeve 10 outside, and the outer side of the sleeve 10 is fixedly connected with an arc clamp 12. The design of the sliding square block 8 and the sliding rod 9 makes it easier to move and adjust the position of the wiring harness during installation and maintenance, thereby improving the operability and installation efficiency of the wiring harness. The sliding rod 9 and the sleeve 10 are sleeved with an elastic component outside, and the elastic component includes a spring 11, which is sleeved on the outside of the sliding rod 9 and the sleeve 10. One end of the spring 11 is fixedly connected to the inner wall of the sliding square block 8, and the other end of the spring 11 is fixedly connected to the outer side of the arc clamp 12. The existence of the elastic component ensures the stability and reliability of the sliding square block 8 and the sliding rod 9. The use of the spring 11 enables the wiring harness to flexibly adapt to different vibrations and external forces within a certain range, thereby reducing the risk of damage to the wiring harness.

[0025] Working principle: First, the presence of the insulating outer coat 1 protects the internal wires and connectors from damage by the external environment, such as moisture, dust, chemicals, etc., thereby ensuring the normal function of the vehicle. Inside the insulating outer coat 1, the role of the flame retardant layer 2 is to prevent the spread of flames and slow down the burning speed of the wiring harness in the event of fire or high temperature, thereby increasing the safety of the vehicle. The reinforcement layer 3 enhances the structural stability and durability of the wiring harness, and prevents the wiring harness from being damaged by vibration, stretching or external impact during use, thereby ensuring the stability and function of the wiring harness during vehicle operation. Furthermore, the separation component includes a fixing ring 4 and a wire 5. Through the design of the fixing ring 4, the wire 5 can be arranged in an orderly manner, which not only ensures the neatness of the wiring harness, but also reduces the impact of electromagnetic interference and improves the stability and performance of the system. The anti-tensile metal ring piece 6 provides additional support and protection when the wiring harness is subjected to tensile force, preventing the wiring harness from breaking or being damaged. The anti-interference metal ring 7 provides shielding protection to prevent external electromagnetic interference from affecting the wiring harness, ensuring the stability and reliability of signal transmission. The design of the sliding square block 8 and the sliding rod 9 makes it easier to move and adjust the position of the wiring harness during installation and maintenance, improving the operability and installation efficiency of the wiring harness. The presence of the elastic component ensures the stability and reliability of the sliding square block 8 and the sliding rod 9, allowing the wiring harness to flexibly adapt to different vibrations and external forces within a certain range, reducing the risk of damage to the wiring harness.
