[0014] The inner wall of the outer sleeve is fixedly connected with limiting plates, and the number of the limiting plates is four.

[0015] By adopting the technical scheme, the limiting plates can limit the movement of the moving plate and support the moving plate to a certain extent.

[0016] As a further description of the above technical scheme:

[0017] The side wall of the moving plate is provided with limiting grooves, the number of the limiting grooves is multiple, and the limiting plates are located inside the limiting grooves.

[0018] By adopting the technical scheme, the limiting grooves cooperating with the limiting plates can limit the movement of the moving plate.

[0019] As a further description of the above technical scheme:

[0020] The side wall of the outer sleeve is provided with first heat dissipation grooves, and the number of the first heat dissipation grooves is multiple.

[0021] By adopting the technical scheme, the first heat dissipation grooves can connect the inside of the outer sleeve with the outside, so that the heat in the outer sleeve can be dissipated.

[0028] By employing the above technical solution, the vehicle air conditioning wiring harness assembly of this utility model has at least the following beneficial effects:

[0029] Compared to existing technologies, this vehicle air conditioning wiring harness assembly, through an inner sleeve, an outer sleeve, a deflecting arm, a moving plate, a spring, a moving rod, a piston disc, and an oil drain hole, allows for vertical movement of the inner and outer sleeves when the vehicle encounters bumpy roads. The upward movement of the outer and inner sleeves causes the lower deflecting arm to deflect, increasing the angle between adjacent lower deflecting arms. This, in turn, moves the adjacent lower moving plate away, stretching the adjacent lower spring, which in turn moves the adjacent moving rod and piston disc away. This allows hydraulic oil to flow through the oil drain hole on the piston disc, achieving a buffering effect and reducing the amplitude of the inner sleeve's movement. After the vibration subsides and the bumps disappear, the adjacent springs reset, causing all components to return to their original state. Compared to existing wiring harnesses, which use cable ties to fix the harness in sections at predetermined positions, when a car encounters bumpy roads, the continuous vibration can cause the cable ties to loosen, resulting in the wiring harness shaking with the vehicle's vibrations and rubbing against internal vehicle components, leading to wear and tear, reduced lifespan, and increased replacement costs. This vehicle air conditioning wiring harness assembly can mitigate the impact of vehicle vibrations on the wiring harness through buffering, avoiding direct impact on the wiring harness and reducing the probability of malfunctions caused by vibration.
