The work of the presently named inventors, to the extent the work is described in this background section, as well as aspects of the description that can not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
[0003] In a motor vehicle, lighting devices or signal indicating devices such as vehicle lamps are a guarantee for safe driving. The light emitting module of a vehicle lamp needs to be adjusted at an angle around a horizontal or vertical axis so that the light beam emitted by the vehicle lamp meets the relevant regulations or the requirements for safe driving.
[0004] In the prior art, the structure of vehicle lamps is becoming more and more complex, and high beam and low beam are implemented using different modules, which makes the light beam adjustment more and more complex. At present, micro-alignment brackets or tools are usually added to fine-tune the light emitting module, but these not only complicate the operation, but also increase the production cost of the vehicle lamp.
[0005] Therefore, a new light beam adjusting mechanism is urgently needed. SUMMARY

[0008] In an embodiment of the present application, the threads of the adjusting member and the light emitting module support are alternatively provided on the inner surface of the adjusting member and the outer surface of a portion of the light emitting module support, respectively.
[0009] In an embodiment of the present application, the fixed member is threadedly connected with the light emitting module through the adjusting member.

[0025] Hereinafter, the present disclosure will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are shown. The present disclosure may, however, be embodied in different forms, and should not be construed as being limited to the embodiments set forth herein. Such embodiments of the present disclosure provided herein are to make the present disclosure thorough and complete and fully convey the scope of the present disclosure to those skilled in the art. In the drawings, the thickness and area of layers can be exaggerated for clarity. Throughout the specification, like reference numerals will be used to designate like elements. For different embodiments, elements can have different relative relationships and different positions.
[0026] The present application proposes a light beam adjusting mechanism, as shown in Figures 1 to 6 The light beam adjusting mechanism 1 includes a light emitting module 10 in which a first light source emitting a light beam is accommodated, a light emitting module support 30 for supporting the light emitting module 10, a fixing member 11 connected to the light emitting module 10, and an adjusting member 12 rotatably disposed between the light emitting module 10 and the fixing member 11, the adjusting member 12 being provided with a screw thread to be threadedly connected to a screw thread portion provided on the light emitting module support 30, the light emitting module support 30 threadedly connected to the adjusting member 12 having a linear movement ability by rotating the adjusting member 12, and the light emitting module 10 being linearly moved to adjust the light beam emitted from the first light source.
[0027] The light beam adjusting mechanism of the present application can adjust the light beam angle or irradiation direction in the light emitting module only by rotating the adjusting member, thereby saving the manufacturing cost and installation adjustment time of the vehicle lamp.
[0028] In an embodiment of the present application, as shown in Figures 1 to 6 The outer surface of the adjusting member 12 is provided with a screw thread to be threadedly connected to the screw thread provided on the light emitting module support 30, for example, the light emitting module support 30 is provided with a through hole into which the support leg 101 of the light emitting module 10 is inserted, at least a portion of the through hole is provided with a screw thread, the support leg 101 is inserted into the at least a portion of the through hole, and the fixing member is threadedly connected to the support leg 101 of the light emitting module 10.
[0029] In one embodiment of the present application, as shown in Figures 1 to 6 The fixing member 11 can be a screw or a bolt, so that the light beam adjusting mechanism can be achieved conveniently and at low cost, and finally the vehicle lamp can be assembled conveniently and at low cost.
[0030] As shown in Figure 5 and Figure 6 The adjusting member 12 can be provided with a through hole in the inside, the through hole can not be provided with a thread, the fixing member 11 can pass through the through hole, and the fixing member 11 can not contact the surface of the through hole of the adjusting member 12. The adjusting member 12 is substantially cylindrical, and the outer surface of the cylinder is provided with a thread, and a flange 121 is provided at one axial end. The flange 121 can be circular or polygonal, and the outer diameter or outer edge is greater than the outer diameter of the cylinder. The adjusting member 12 abuts against the fixing member 11 by means of the flange 121, and can rotate relative to the fixing member 11.
[0031] As shown in Figures 1 to 6 The fixing member is screwed with the light emitting module 10 through the adjusting member 12. The length of the adjusting member 12 is substantially equal to the distance between the fixing member 11 and the support leg 101. Specifically, the support leg 101 is inserted into the through hole of the light emitting module support 30 and is screwed with the fixing member 11, the support leg 101 is provided with a threaded hole, the fixing member 11 is connected into the threaded hole, and the length of the adjusting member 12 is equal to the interval distance between the support leg 101 and the surface of the fixing member 11 that is in contact with the adjusting member 12. Preferably, the length of the adjusting member 12 is equal to the interval distance between the support leg 101 and the surface of the fixing member 11 that is in contact with the adjusting member 12.
[0032] As shown in the figure, as shown in Figures 1 to 6 The adjusting member 12 is provided with a thread, which can be screwed with the threaded part provided on the light emitting module support 30, so that the rotation of the adjusting member 12 should make the light emitting module support 30 screwed with the adjusting member 12 move along the axial direction of the adjusting member 12, i.e. the axial direction of the cylinder. When the light emitting module support 30 is fixed and does not move, it will cause the linear motion of the light emitting module 10, and finally adjust the light beam emitted from the light source. Thus, compared with the prior art, the adjustment of the light beam of the light source can be achieved conveniently and quickly without setting up a micro-sighting or closing tool.
[0033] In one embodiment of the present application, alternatively, the thread of the adjusting member 12 is provided on the inner surface to be screwed with the outer thread provided on the light emitting module support 30. Or it can be connected with the light emitting module support 30 through a sleeve or the like, so as to obtain the same technical effect as the above embodiment.
[0034] In one embodiment of the present application, the light emitting module 10 is swung in the vertical direction under the drive of the light beam adjusting mechanism.
[0035] In one embodiment of the present application, the light beam adjusting mechanism can be applied to a motor vehicle, for example, a headlight of a vehicle, and the light source in the light emitting module 10 can emit a high beam.
[0036] In one embodiment of the present application, as shown in FIG. 1, a second light emitting module 20 is also supported on the light emitting module support 30, and the second light emitting module 20 can emit a low beam. That is, the first light emitting module 10 is different from the second light emitting module 20. Two kinds of light emitting modules are supported on the light emitting module support 30. Figures 1 to 2
[0037] The light beam adjusting mechanism of the present application can adjust the angle and irradiation direction of the light beam, for example, a high beam, in the light emitting module only by rotating one or more adjusting members, without replacing the entire support or using other tools, thereby saving the manufacturing cost and installation and adjustment time of the vehicle lamp and flexibly adjusting various different light emitting modules.
