Problems solved by technology

Due to the limitations of this structure, the reflector falls off or the threads of the dimming rod and lifter are damaged due to over-adjustment during production off-line inspection and user use, and eventually the entire front panel cannot be replaced because the dimming mechanism cannot be replaced. The lighting assembly is scrapped
Unnecessary loss to OEMs and customers

Embodiment Construction

[0018] Such as Figure 1-2 As shown, the present invention uses an external dimming structure to be clamped to the headlight housing and separated from the headlight assembly, which is convenient for replacement and maintenance.

[0019] In the present invention, the light adjusting rod 1 is inserted into the mounting base 7, and the light adjusting rod threaded section 2 engages with the thread 11 of the mounting base; the connector 10 is sleeved into the other end of the installation base 7, and the jump tooth 12 inside the connector 10 is sleeved in On the dimmer gear section 5; the side of the mounting base 7 is provided with an adjustment knob 8 that engages with the connector gear 9. The adjustment knob 8 is rotated to drive the dimmer lever 1 to adjust the headlight, and the connector 10 The internal jump tooth 12 realizes a self-protection function when over-adjusted.

[0020] Two limit rings 4 are arranged between the threaded section 2 of the light adjusting rod and the ...

Abstract

The invention discloses a light-regulating structure of an automobile headlamp. The light-regulating structure is characterized in that a light-regulating rod is inserted into an installation base, and the thread section of the light-regulating rod is meshed with the thread of the installation base; a connector is sleeved in the other end of the installation base, and the jumping teeth in the connector are sleeved on the gear section of the light-regulating rod; and the side face of the installation is provided with a adjusting knob which is meshed with the gear of the connector. The structure is adopted, the light-regulating structure disclosed by the invention has the advantages that 1, the self-protection function can be realized when excessive adjustment is carried out; 2, the light-regulating structure is separated form a headlamp assembly, and the light-regulating structure can be conveniently changed and maintained; 3, the structure is simple, and the manufacturing cost is low; and 4, the disassembly and assembly are rapid, and the operation is convenient and fast.

Description

Technical field [0001] The invention relates to the field of automotive lighting, and in particular to a dimming structure for automotive headlamps. Background technique [0002] At present, most of the dimming mechanisms of automobile headlights are metal screws directly crimped onto the headlight housing, and then connected to the headlight reflector through a lifter and an adapter mechanism. Due to the limitation of this structure, in the process of off-line inspection and user use, over-adjustment may cause the reflector to fall off or the thread of the dimmer rod and the lifter is damaged, and finally the entire front is caused by the inability to replace the dimmer mechanism. The lamp assembly is scrapped. It is an unnecessary loss to the OEM and customers. [0003] It is a problem that the prior art needs to solve to provide an externally replaceable dimming mechanism that can realize a self-protection function when over-adjusted. Summary of the invention [0004] The tech...
