Automobile lamp light adjusting structure and automobile

Abstract

This invention discloses a vehicle headlight dimming structure and an automobile. The dimming structure includes a dimming screw, which is directly or indirectly connected to the headlight body via its connecting thread. It also includes a sleeve attached to the head of the adjusting screw. The sleeve is detachably connected to a dimming bracket and corresponds to the position of the adjusting groove on the head of the dimming screw. The sleeve has a clearance portion to facilitate the insertion of an adjusting tool into the adjusting groove. Using this structure, rotating the dimming screw from the front causes the bracket to rotate. Furthermore, this dimming nut is easy to install, requiring only manual screwing, eliminating the need for a special tool to press it in.

Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, specifically to an automotive lighting dimming structure and an automobile using this structure. Background Technology

[0002] The existing dimming systems for combination headlights are basically dimmed from rear to front, so there are two dimming screws protruding from the lamp body.

[0003] Reference Figure 1 and Figure 2 The diagram shows a commonly used dimming structure, where 1 is a dimming nut, 2 is a dimming bracket, 3 is a dimming screw, and 4 is the lamp body. The conventional dimming method involves dimming from the rear of the lamp body (referring to...). Figure 2 (Below the middle image) Rotate the dimming screw 3. The back-and-forth movement of the dimming screw drives the dimming nut 1 and the dimming bracket 2 to move, thereby achieving the purpose of dimming. This method requires the use of a sealed dimming screw 3. This type of dimming screw may cause poor sealing. In addition, the installation method of the dimming nut 1 is also relatively complicated. For example, a jig is required to press it in forcefully. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a vehicle headlight dimming structure that can effectively reduce assembly difficulty and maintain a stable sealing effect.

[0005] The technical problem it aims to solve can be addressed through the following technical solutions.

[0006] A vehicle headlight dimming structure is characterized by including a dimming screw, which is directly or indirectly connected to the headlight body via its connecting thread; and a sleeve attached to the head of the adjusting screw, which is detachably connected to a dimming bracket and corresponds to the position of the adjusting groove on the head of the dimming screw, wherein the sleeve has a clearance portion to facilitate the insertion of an adjusting tool into the adjusting groove.

[0007] As a further improvement to this technical solution, the socket is a rotating connector, which includes at least a first rotating position and a second rotating position. When the rotating connector rotates to the first rotating position, it is connected to the dimming bracket. When the rotating connector rotates to the second rotating position, it is separated from the dimming bracket.

[0008] In a preferred embodiment of the present invention, the shank of the adjusting screw is provided with a limiting retaining ring that protrudes radially outward, and the limiting retaining ring is located at the end of the thread on the side of the adjusting thread near the head of the adjusting screw.

[0009] As a further improvement to this technical solution, the dimming screw is connected to the vehicle lamp body via a linkage rod.

[0010] Another technical problem to be solved by the present invention is to provide a car that adopts the above-mentioned headlight dimming structure.

[0011] Furthermore, the combination headlights of the vehicle employ the aforementioned headlight dimming structure.

[0012] The dimming structure employing the above technical solution effectively solves the problem of dimming only being adjustable from the rear, compared to conventional dimming techniques. Furthermore, the method is simpler and more convenient to operate; dimming can be completed simply by rotating the screw from the front. Attached Figure Description

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 3 and Figure 4 As shown, this invention provides a new dimming method, which differs from previous dimming methods in that the dimming is performed from directly in front of the lamp (meaning...). Figure 4 (as shown in the diagram above), this method can solve the problem of using sealed screws on the back of the lamp body when fine-tuning the light.

[0022] like Figure 4The tail of the dimming screw 300 is connected to the linkage rod 400 via the adjusting thread 320, and the linkage rod 400 is further connected to the headlight body.

[0023] The dimming screw 300 has an adjustment groove 311 on its screw head 310. The dimming nut 100 is tightened and positioned, and is snapped onto the dimming bracket 200. Corresponding to the adjustment groove 311 on the screw head, the adjustment nut 100 has a clearance groove 110.

[0024] like Figure 5-7 As shown, the state changes of the dimming nut 100 before and after installation are illustrated. The dimming bracket 200 has a mounting hole 210, as shown. Figure 6 As shown, this is the newly installed state. At this time, the dimming nut 100 is still in a position for easy disassembly. Rotate the dimming nut 90 degrees, and after it rotates, the dimming nut is tightened onto the dimming bracket 200, thus completing the assembly. At this point, the rotating position of the dimming nut is the locking position (see...). Figure 7 ).

[0025] An annular retaining ring 330 protruding from the body is provided on the rod of the adjusting screw 300 near the boss 410 of the linkage rod 400, so as to control the thread feed depth of the adjusting screw 300 relative to the linkage rod 400 or lock the relative position between the two.

[0026] That is, the dimming nut 100 used in this technical solution is a nut with a front opening. The nut may also have grooves (cross-shaped or star-shaped) for easy tightening and loosening, allowing it to be easily screwed onto the dimming bracket with a tool. The adjustment groove 311 of the screw head 310 can have a cross-shaped or star-shaped groove. The dimming tool enters the grooved dimming screw through the front-opening dimming nut 100 and touches its adjustment groove for adjustment, thereby adjusting the back-and-forth movement of the dimming screw 300, further driving the movement of the dimming bracket 200 to achieve the purpose of dimming.

[0027] The dimming method provided by the present invention involves rotating the dimming screw from the front. The back-and-forth movement of the dimming screw drives the rotation of the bracket. Moreover, this dimming nut is easy to install, requiring only manual screwing, eliminating the need for a special jig to press the dimming nut in.
