Description

Technical Field

[0001] The invention relates to the field of vehicle parts, and in particular to a vehicle wiring harness fixing device and a vehicle wiring harness movement control method. Background Art

[0002] There are many deficiencies in the vehicle wiring harness fixing devices in the prior art, such as low flexibility and space utilization. More specifically, the wiring harness fixing devices in the prior art usually completely fix the wiring harness. If the wiring harness is too long, redundant wiring harnesses will be locally accumulated, increasing the risk of interference, while if the wiring harness is too short, there is a risk of tearing. Therefore, the wiring harness length needs to be continuously corrected through prototype vehicle tests, resulting in a long design cycle and high material costs. At the same time, designers need to fully consider the positions of various components in the wheel area under various working conditions to ensure that there is no contact and interference between the wiring harnesses. Usually, the wiring harness can only be fixed outside the component's motion envelope, further compressing the insufficient wiring space.

[0003] In addition, existing harness fixing devices are prone to fatigue and wear. When the harness moves with the moving parts, one end of the harness will move with the moving parts. Since the other end is completely restrained by the fixing device, this section of the harness will be subjected to large bending during the movement, which will lead to fatigue and wear, and ultimately reduce the service life.

[0004] In particular, for rubber-wheeled trams, the air pressure inside the wheel is relatively high, and the size of the rubber wheel should not be too small. Therefore, compared with traditional steel-wheeled trams, there are larger wheel bags. In order to avoid the wheel bags from excessively occupying the passenger compartment space, the wheel area space is strictly limited. In addition, compared with trams, rubber-wheeled trams have full-axle steering functions, higher axle freedom, and more complex driving conditions. Therefore, due to the small space and many moving parts in the wheel area of ​​rubber-wheeled trams, the risk of interference and wear of the wiring harness connected to this area is relatively high. The wiring harness fixing devices in the prior art mostly completely limit the freedom of the wiring harness to constrain the wiring harness, thereby avoiding contact and interference with surrounding components. The solution cannot meet the wiring harness assembly requirements of special vehicles such as rubber-wheeled trams.

[0005] In order to overcome the above-mentioned defects of the prior art, the art urgently needs a vehicle wiring harness fixing device and a method for controlling the movement of the vehicle wiring harness. Through the clever setting of the device structure, the wiring harness can move with the wheel and has the characteristics of adaptability. It improves the space utilization without contact interference, and can also reduce the bending of the wiring harness and increase the service life of the wiring harness. Summary of the invention
