Description

External front fog lamp dimming mechanism and automobile front fog lamp with same

Technical Field

The utility model relates to an automobile lamp technical field, concretely relates to external front fog lamp dimming mechanism and have its car front fog lamp.

Background

The existing light adjusting mechanism of the European front fog lamp is very complex. As shown in fig. 1, there are several mechanical structures of engagement: the adjusting rod 100 is engaged with the extension rod 110 through a bevel gear structure, the extension rod 110 is engaged with the gear rod 120 through a cross nail structure, and the gear rod 120 is engaged with the gear ring 130 through threads and gears. As shown in fig. 2, the gear ring 130 and the reflector 140 have a structure that they are engaged with each other through three point surfaces. As the gear ring 130 rotates, the elevation of the contact surface causes the mirror 140 to rotate up or down. This design places excessive demands on the manufacturing and assembly accuracy of the parts. Therefore, the manufacturability of the set of dimming mechanisms is not high.

Alternatively, the front fog light dimmer mechanism commonly used by suppliers in the present system is configured as shown in fig. 3 (lamp housing not shown), and the driving member 210 passes through the lamp housing to be connected to the reflector 250. A sealing structure is required between the transmission member 210 and the housing, as shown in fig. 4. The sealing ring 220 is used to ensure the sealing performance between the transmission member 210 and the housing 260. There are potential failure modes for this set of dimming mechanisms: when the sealing structure is invalid, water enters the lamp body.
