[0002] The conventional light-adjusting gear currently used in automobile lamps has the defect of idle stroke, cannot realize precise light adjustment, and cannot meet the high-quality light adjustment requirement, thus bringing bad user experience. CONTENT OF THE INVENTION

[0003] In order to make up for the above shortcomings, the present application provides a novel light-adjusting worm gear structure, aiming at improving the problem that the conventional light-adjusting gear currently used in automobile lamps has the defect of idle stroke, cannot realize precise light adjustment, and cannot meet the high-quality light adjustment requirement.

[0004] The present application is implemented in the following manner:

[0005] The present application provides a novel light-adjusting worm gear structure, comprising an adjusting screw, a novel worm gear, a joint adjusting rod and a novel worm, the novel worm gear is fixed on the outer wall of the adjusting screw, the novel worm and the joint adjusting rod are fixed together, and the novel worm gear and the novel worm are engaged.

[0006] In an embodiment of the present application, an operation groove is formed on the adjusting screw.

[0007] In an embodiment of the present application, the adjusting screw and the joint adjusting rod are perpendicular to each other.

[0008] In an embodiment of the present application, the number of engaging teeth between the novel worm gear and the novel worm is greater than three.

[0009] The present application has the following beneficial effects: the novel light-adjusting worm gear structure obtained by the above design is different from the existing lamps, the structure of the worm gear makes the engagement between the novel worm gear and the novel worm more compact, avoids idle stroke, realizes precise light adjustment, can meet the high-quality light adjustment requirement, and brings better user experience.

[0017] In order to make the purpose, technical scheme and advantages of the embodiment of the application more clear, the technical scheme in the embodiment of the application will be described clearly and completely below in combination with the drawings in the embodiment of the application. Obviously, the described embodiment is part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0018] EMBODIMENT

[0019] Please refer to Figure 1 - Figure 5 The application provides a technical scheme: a new type of light adjusting worm gear structure, which comprises an adjusting screw 110, a new type of worm wheel 120, an adjusting screw 130 and a new type of worm 140. The new type of worm wheel 120 is fixed on the outer wall of the adjusting screw 110. The new type of worm 140 and the adjusting screw 130 are fixed together. The new type of worm wheel 120 and the new type of worm 140 are engaged. The adjusting screw 110 is provided with an operation slot 150. The operation slot 150 is arranged to facilitate the rotation operation of the adjusting screw 110. The adjusting screw 110 and the adjusting screw 130 are perpendicular to each other. The number of engaged teeth between the new type of worm wheel 120 and the new type of worm 140 is greater than three.

[0020] Specifically, the working principle of the new light adjusting worm and gear structure is as follows: in use, the meshing between the new worm wheel 120 and the new worm 140 realizes the transmission between the adjusting screw rod 110 and the connecting adjusting rod 130, and the meshing between the new worm wheel 120 and the new worm 140 is more than three teeth and has no idle stroke. The new light adjusting worm and gear structure is different from the existing lamps, the structure of the worm wheel and the worm makes the meshing between the new worm wheel 120 and the new worm 140 more compact, avoids the idle stroke, realizes precise light adjustment, can meet the high-quality light adjustment requirement, and brings better use experience to the user.

[0021] The above only describes the embodiments of the present application and is not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
