Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology and relates to a wiring fixing mechanism on the back of an automotive lamp housing. Background Technology

[0002] Automotive lights are the core components of a vehicle's lighting and signaling system. They are primarily used to provide road illumination (such as low beam headlights and high beam headlights) at night or in low visibility environments, indicate vehicle position (side marker lights), convey driving intentions (turn signals and brake lights), and enhance driving safety (fog lights and reversing lights). Modern automotive lights typically use LED, xenon, or halogen light sources and are integrated into the front, rear, or sides of the vehicle, combining functionality with aesthetic design. Some high-end models are also equipped with intelligent lighting technologies (such as adaptive headlights and matrix LEDs), which can automatically adjust the light pattern to avoid glare. Automotive lights must meet strict regulatory standards (such as ECE and SAE) to ensure that brightness, color temperature, and illumination range meet safety requirements. At the same time, their structure must be waterproof, dustproof, and resistant to high temperatures and vibrations to cope with complex driving environments.

[0003] However, during the installation of car lights, if the wiring is not properly secured, the loose wiring harness will continuously rub against the lamp housing or surrounding metal parts during vehicle operation. This friction will first cause the outer insulation layer of the wire to gradually wear down and become thinner, eventually breaking completely, exposing the internal metal conductor directly. Once the exposed conductor comes into contact with the metal parts of the vehicle body, it will form a short circuit, causing an abnormal increase in current. This can lead to malfunction of the headlights or blown fuses, or even cause the wiring to overheat or burn out related electrical components. Utility Model Content

[0026] The circuit winding assembly includes a winding post 301; the winding post 301 is provided in the middle of the inner side of the circuit assembly 103; a serrated block a302 is fixedly connected to one end of the winding post 301 near the lampshade 102; a rotating head 303 is provided at one end of the winding post 301 away from the serrated block a302; a serrated block b304 is provided on the outer side of the rotating head 303; the serrated block b304 and the serrated block a302 are respectively slidably engaged with the serrated groove 107; a rotating mechanism is provided between the rotating head 303 and the winding post 301.

[0027] The rotating mechanism includes a rotating ring 502; the rotating ring 502 is fixedly connected to one end of the winding column 301 away from the sawtooth block a302; a rotating groove 501 is provided on the inner side of the rotating head 303; the rotating ring 502 is located inside the rotating groove 501 and is rotatably connected to the rotating groove 501.

[0028] The circuit connection assembly includes a pair of connecting wires 201; multiple sets of connecting wires 201 are fixedly connected to the end of the lamp holder 105 away from the bulb 106; a plug-in connector a202 is installed on the inner side of the serrated block a302; the connecting wires 201 are plugged into the plug-in connector a202; a connecting wire 203 is wound around the outer side of the winding column 301; the end of the connecting wire 203 near the plug-in connector a202 is plugged into the plug-in connector a202; a circuit limiting groove 305 is opened on the inner side of the rotating head 303; the end of the connecting wire 203 away from the plug-in connector a202 passes through the circuit limiting groove 305 and is fixedly connected to the plug-in connector b204.

[0029] During operation, the bulb 106 is first installed inside the lamp holder 105. Then, the operator installs the connector b204 on the controller device. Next, the connecting wire 201 and the connecting wire 203 are plugged into the inside of the connector a202. Then, the operator rotates the rotating head 303 and winds the excess connecting wire 203 around the outside of the winding post 301 through the wire limiting groove 305. After winding, the sawtooth block a302 and the sawtooth block b304 are placed inside the sawtooth groove 107.

[0030] The saw teeth on the sawtooth groove 107 are misaligned with the saw teeth on the sawtooth blocks a302 and b304 to prevent the wire winding assembly from rotating under non-human conditions. The reset assembly prevents the wire winding assembly from sliding out from the inside of the sawtooth groove 107, thereby fixing the winding post 301 after winding the wire to the inside of the lamp housing body 101, and thus fixing the wire.

[0034] During operation, the rotating head 303 is pulled out from the inside of the sawtooth groove 107 by the pull ring 601, so that the sawtooth block b304 is no longer engaged with the sawtooth groove 107. Then, the operator rotates the rotating head 303 and winds the connecting wire 203 around the outside of the winding post 301 through the wire limiting groove 305. After winding, the operator rotates the sawtooth block b304 to the appropriate position so that the sawtooth block b304 engages with the saw teeth on the sawtooth groove 107. Then, the rotating head 303 is released, so that the spring 402 drives the sawtooth block b304 to return to the original position through the rotating mechanism, thereby completing the locking of the rotating head 303.
