The technical problem to be solved can be implemented by the following technical scheme.

A car light dimming structure is characterized by comprising a dimming screw, wherein the dimming screw is directly or indirectly connected with a car light body through a connecting thread; still including one set connect in the cup joint piece of adjusting luminance screw head, cup joint piece detachable connects on adjusting luminance the support, with adjust luminance screw head adjustment tank position corresponding, set up the portion of dodging that the adjustment tool of being convenient for stretched into this adjustment tank on the cup joint piece.

As a further improvement of the technical solution, the socket joint member is a rotating connection member, the rotating connection member at least includes a first rotating position and a second rotating position, the rotating connection member rotates to the first rotating position, the rotating connection member is connected with the dimming support, and the rotating connection member rotates to the second rotating position, the rotating connection member is separated from the dimming support.

As the utility model discloses a preferred embodiment, be equipped with on the body of rod of the screw of adjusting luminance along radial outside bellied spacing retaining ring, spacing retaining ring is located connecting thread is close to the screw thread end position of adjusting luminance screw head one side.

Also as the further improvement of the technical proposal, the light adjusting screw is connected with the lamp body of the car lamp through a linkage rod.

The utility model discloses another technical problem that will solve provides an adopt the car of above-mentioned car light structure of adjusting luminance.

Furthermore, the combined headlamp of the automobile adopts the automobile lamp dimming structure.

Compared with the conventional dimming technology, the dimming structure adopting the technical scheme well solves the problem that dimming can be only adjusted from the right back, and the method is simple and convenient to operate. The dimming operation can be completed only by rotating the screw from the right front.

Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 3 and 4, the present invention provides a new dimming method, which is different from the previous dimming method in that the dimming is performed from the front of the lamp (referring to the direction of the drawing of fig. 4), and this method can solve the problem of the sealing screw used at the back of the lamp body during the fine dimming.

As shown in fig. 4, the tail of thelight adjusting screw 300 is connected to thelinkage rod 400 via the adjustingthread 320, and thelinkage rod 400 is further connected to the lamp body.

Thescrew head 310 of thelight adjusting screw 300 is provided with an adjustingslot 311, and thelight adjusting nut 100 is fastened and positioned to be connected to the light adjustingbracket 200. The adjustingnut 100 is provided with an avoidinggroove 110 corresponding to the adjustinggroove 311 at the head of the screw.

As shown in fig. 5 to 7, which illustrate the state change before and after the installation of thedimming nut 100, thedimming bracket 200 is provided with aninstallation hole 210, as shown in fig. 6, in a state of just being installed, thedimming nut 100 is still at a position convenient for disassembly, the dimming nut is rotated, after the dimming nut is rotated by 90 degrees, the dimming nut is screwed on thedimming bracket 200, and then the dimming nut is assembled in place, and at this time, the rotation position of the dimming nut is a locking position (see fig. 7).

An annularlimiting retainer ring 330 protruding out of the body is arranged on the body of thedimming screw 300 close to theboss 410 of thelinkage rod 400 so as to control the thread feeding depth of thedimming screw 300 relative to thelinkage rod 400 or lock the relative position of thedimming screw 300 and thelinkage rod 400.

That is, thelight adjusting nut 100 used in the present embodiment is a nut that is opened on the front surface. And the nut can also be provided with a line (cross line or plum line) which is convenient to screw and dismount, so that the nut can be conveniently screwed into the dimming support by a tool. The lines of the adjustingslot 311 of thescrew head 310 may be cross lines or quincuncial lines, and the dimming tool enters the grooved dimming screw with lines through thedimming nut 100 opened on the front side and contacts the adjusting slot to adjust, so as to adjust the front-back movement of thedimming screw 300, and further drive the movement of thedimming support 200 to achieve the purpose of dimming.

The utility model provides an above-mentioned mode of adjusting luminance is for following the rotatory screw of adjusting luminance in dead ahead, and the screw seesaw of adjusting luminance drives the rotation of support, and this kind of dimming nut simple to operate, only need manual screw in can, no longer need go the nut of adjusting luminance of impressing with special mould.
