Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness structures, in particular to an automobile exterior rearview mirror wiring harness assembly. Background Art

[0002] Nowadays, the exterior rearview mirrors equipped in cars have many functions, such as turn prompts, entry and exit lighting, warning of approaching vehicles, automatic folding, and automatic flipping when reversing. Therefore, an assembly consisting of multiple wiring harnesses is required to connect to the vehicle computer for control.

[0003] The publication number (CN212473280U) discloses an automatic folding harness assembly for a rearview mirror. The automatic folding harness assembly for a rearview mirror consists of a 12V relay, a relay fixing bracket, a harness trunk, and a harness docking sheath. When the 12V relay is powered on, the internal contacts are connected to the load circuit, and two groups of wires form a closed loop in the internal pins of the 12V relay. One group of wires inputs a rearview mirror folding control signal and outputs a rearview mirror folding signal to the rearview mirror motor, and the other group of wires inputs a rearview mirror deployment control signal and outputs a rearview mirror deployment signal to the rearview mirror motor. The rearview mirror is automatically folded and deployed by controlling the rearview mirror motor.

[0004] When the existing automobile rearview mirror wiring harness is connected to the inside of the exterior rearview mirror, since the rearview mirror needs to be rotated, the wiring harness may become loose after long-term use, which may lead to damage to signal transmission and failure of rearview mirror control. Summary of the invention

[0013] The utility model provides a wiring harness assembly for an automobile exterior rearview mirror, which has the following beneficial effects:

[0014] (1) In the utility model, the wire harness passes through the fixing strap and is located inside the fixing strap. After being wound around the outer wall of the roller frame, the wire harness passes through the inside of the positioning tube. The wire harness squeezes the rubber pad. The rubber pad is subjected to the force from the outside and drives the connecting plate to squeeze the first spring. At this time, the connecting plate drives the rotating shaft to flip. After the first spring is subjected to the force from the outside, it gives the connecting plate a reverse force to drive the rubber pad to squeeze and fix the wire harness. The screw rod rotates and drives the slider to move inside the movable groove. When the slider moves, it drives the fixing strap to move downward to position the wire harness, thereby preventing it from loosening and bending and maintaining its stability during operation.

[0015] (2) The utility model inserts the insert block into the slot, and the insert block squeezes the limit block. When the limit block is squeezed, it squeezes the second spring, and the limit block is stored in the movable cavity. When the insert block falls off and squeezes the limit block, the second spring is free from external pressure, and the second spring drives the limit block to reset. At this time, the limit block is inserted into the limit groove, and the installation of the roller frame and the mounting base is completed, thereby achieving a quick installation and disassembly state of the overall device, which is convenient for staff to operate.
