Abstract
The utility model relates to a light regulator for vehicle front lamp, comprising an aiming bolt and a retaining member, and is mainly characterized in that the lower part of the shaft shoulder of the aiming bolt is in turn provided with a plain shaft, a fitting surface with concavo-convex lines on the surface and a screw thread; a lasting bowl-shaped flexible retaining member which is connected with the bowl mouth and the casing body is arranged on the fitting surface; the lower part of the screw thread of the aiming bolt is also provided with a regulating piece. The utility model has the characteristics of stable quality of regulating light, good sealing effect, low cost and functions of front and back double regulating lights; the utility model is applicable to front lamp with different structures.
Description
Technical field
The utility model relates to the light modulating device that a kind of automobile head light is used.
Background technology
The light modulating device of known automobile head light, constitute by the light modulation bolt, the rigidity locking shell fragment that are installed on the head lamp housing, rigidity locking shell fragment is contained in the positioning groove of light modulation bolt, by the rotary light adjustment bolt, regulate and the bolted reflecting body of light modulation, to regulate the high and low and left and right position of head lamp range.Because the light modulating device of this kind structure is influenced by the working accuracy of rigidity locking shell fragment thickness, light modulation bolt positioning groove not only, but also be subjected to the influence of wall thickness of headlamp case body, so part processing precision is had relatively high expectations, the first-time qualification rate of assembling is low, has also reduced production efficiency.Simultaneously, because of the part that can't satisfy matching requirements can't utilize once more, so increased considerably productive costs.Secondly, adopt rigidity locking shell fragment to be installed in the interior structure of light modulation bolt positioning groove, be difficult to satisfy this position technical requirements, influence sealing property on the one hand, also be difficult for guaranteeing the light modulation quality on the other hand.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of light modulation steady quality, good airproof performance, and the light modulating device of the low automobile head light of productive costs.
Further technical matters to be solved in the utility model provides a kind of light modulating device with automobile head light of forward and backward two-way dimming function.
Technical problem to be solved in the utility model realizes by following technical proposal: a kind of light modulating device of automobile head light, comprise light modulation bolt and locking piece, it is characterized in that: the shaft shoulder bottom of described light modulation bolt has optical axis, surface to have the attachment face and the screw thread of concave convex texture successively, and the durability bowl-type flexible locking spare that the rim of a bowl and housing join is installed on the attachment face.
Further technical matters to be solved in the utility model is achieved through the following technical solutions: regulating part also is equipped with in the screw thread bottom of light modulation bolt.
After adopting structure of the present utility model, because the durability flexible locking spare of bowl-type is installed on the attachment face of convex-concave surface of light modulation bolt, it is mobile on the one hand flexible locking spare can not to be produced on the attachment face of light modulation bolt, make it to keep each other self-locking state, the rim of a bowl is withstood on the housing of head lamp, mend the crack function by the oneself on the other hand, the rim of a bowl all can join with the head lamp housing, guarantees the sealing property between head lamp housing and the light modulation bolt part and the stability of light modulation.The utility model gone to disappear positioning groove of light modulation bolt has been simplified complicated working accuracy and to the requirement of wall thickness, has been improved the disposable qualification rate of assembling, reduces the tooling cost and the assembly cost of part significantly.Secondly, be connected with one in the screw thread bottom manually or the regulating part of regulating by instrument, also can regulate the high and low and left and right position of head lamp range, be applicable to the head lamp of different structure by its rear portion.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the light modulation bolt arrangement scheme drawing of the another kind of structure of the utility model.
The specific embodiment
The light modulating device of automobile head light as shown in Figure 1, 2, comprise light modulation bolt 1 and locking piece 4, the head of light modulation bolt 1 is a six-sided head, and also have crosshead or manifold on it, the shaft shoulder 1-1 bottom of light modulation bolt 1 has optical axis 1-2, surface to have the attachment face 1-3 and the screw thread 1-4 of concave convex texture successively, one sealing member 2 is set with optical axis 1-2 place and is installed in the sealing member mounting groove of head lamp shell 3, preventing that water from entering in the head lamp, and the optical axis 1-2 at this place also can reduce the wearing and tearing to housing 3 and sealing member 2.The durability bowl-type flexible locking spare 4 that the rim of a bowl 4-1 and head lamp housing 3 join is installed on the attachment face 1-3 of light modulation bolt 1, as shown in Figure 1, the concave convex texture of attachment face 1-3 on the light modulation bolt 1 is a reticulate pattern, also can be as shown in Figure 2, the concave convex texture of attachment face 1-3 on the light modulation bolt 1 is a radial teeth, it perhaps is helical teeth, produce displacement by the concave convex texture on the attachment face 1-3 to prevent flexible locking spare 2, in the vibration processes of vehicle ', remain self-locking state, and, guarantee the reliability of light modulation work, and have better sealing property and water resistance by self benefit crack function.
In order to make things convenient for the user to carry out the upper and lower, left and right position adjustments of headlight range, regulating part 5 also is equipped with in the screw thread 1-4 bottom of light modulation bolt 1, as shown in Figure 2, the screw thread bottom of light modulation bolt 1-4 also has adapter shaft 1-5, rolled perpendicular tooth on the adapter shaft 1-5, can directly carry out light modulation at the rear portion by hand or instrument, easy to adjust, be applicable to the head lamp of different structure.
Claims (3)
