Also, the terms such as "upper," "lower," "left," "right," "middle," and "a" and the like recited in the present specification are merely for descriptive purposes and are not intended to limit the scope of the invention, but are intended to provide relative positional changes or modifications without materially altering the technical context in which the invention may be practiced.

As shown in fig. 1 to 15, the invention provides an illumination lamp for a vehicle, which comprises a housing 1, a reflector 2 installed in the housing 1, a bulb 3 fixedly connected with the reflector 2, a lens 4 installed at the front end of the housing 1, and a rear cover 5 installed at the rear end of the housing 1, wherein the reflector 2 is connected with the housing 1 through a dimming mechanism 6, and the dimming mechanism 6 can drive the reflector 2 and the bulb 3 to rotate relative to the housing 1. The dimming principle of the vehicle lighting lamp in the invention is as follows: the light adjusting mechanism 6 is utilized to drive the reflector 2 and the bulb 3 to rotate relative to the shell 1, so that the irradiation angle of the illuminating lamp for the vehicle is adjusted, namely the light adjustment is realized; the lamp is convenient to use and convenient for the assembly work of the lighting lamp for the vehicle. The vehicle lighting lamp has the advantages of simple integral structure and lower production cost.

As shown in fig. 1 to 7, the housing 1 in this embodiment has a cylindrical shape. As shown in fig. 1, 12 and 13, two positioning grooves 11 are formed on the inner wall of the housing 1 in the present embodiment, as shown in fig. 8 to 10, two positioning shafts 21 are formed on two sides of the reflecting mirror 2, the two positioning shafts 21 are located on the same straight line, and the two positioning shafts 21 are respectively embedded in the two positioning grooves 11. Meanwhile, as shown in fig. 3, 8 and 11, the dimming mechanism 6 includes a dimming driving frame 61 and a dimming shaft 62, one end of the dimming driving frame 61 is connected with the reflecting mirror 2, the other end of the dimming driving frame 61 is connected with the dimming shaft 62, and the dimming shaft 62 is connected with the housing 1. The invention ensures that the reflector 2 can freely rotate around the positioning shaft 21 relative to the shell 1 under the action of external force by utilizing the matching relation of the positioning shaft 21 and the positioning groove 11. In the dimming process, the dimming shaft 62 can drive the dimming transmission frame 61 to move along the axial direction of the dimming shaft 62 relative to the shell 1, and the dimming transmission frame 61 applies corresponding force to the reflecting mirror 2 in the moving process, so that the reflecting mirror 2 is driven to rotate relative to the shell 1 around the positioning shaft 21, and the adjustment of the light irradiation angle is realized.

As shown in fig. 3 and 8, the positioning shaft 21 is perpendicular to the axis of the housing 1 in this embodiment, and the dimming shaft 62 is parallel to the axis of the housing 1. The dimming transmission frame 61 applies a force parallel to the axis of the housing 1 to the mirror 2 during the axial movement along the dimming axis 62, the force being perpendicular to the positioning axis 21, thereby driving the mirror 2 to rotate about the positioning axis 21 with respect to the housing 1 and achieving vertical dimming.

Meanwhile, as shown in fig. 1 and 3, a limit flange 621 abutting against the housing 1 is provided at the front end of the dimming shaft 62, and the rear end of the dimming shaft 62 is screwed with the dimming transmission frame 61. The dimming mechanism 6 further includes an elastic member 63, and front and rear ends of the elastic member 63 are respectively abutted against the housing 1 and the dimming transmission frame 61. Under the abutting action of the elastic element 63 and the housing 1, the elastic element 63 will apply a backward force to the rear ends of the dimming transmission frame 61 and the dimming shaft 62, and the dimming shaft 62 will not move in the front-rear direction relative to the housing 1 in the normal state under the abutting action of the limiting flange 621 and the housing 1. Thus, in the dimming process, only the dimming shaft 62 needs to be rotated, and under the threaded connection effect of the dimming shaft 62 and the dimming transmission frame 61, the dimming shaft 62 drives the dimming transmission frame 61 to move relative to the housing 1 along the length direction of the dimming shaft 62, so as to realize the dimming.

As shown in fig. 1 and 3, in this embodiment, the elastic element 63 is a spring 631, and the spring 631 is sleeved on the dimming shaft 62, so that the dimming shaft 62 is utilized to effectively position the spring 631, so as to ensure that the spring 631 deforms along the length direction of the dimming shaft 62 in the dimming process, and avoid the deviation of the installation state of the spring 631. Meanwhile, in the present embodiment, a first connection hole 611 is formed at one end of the dimming transmission frame 61 connected to the dimming shaft 62, and a threaded portion 612 protruding inwards and connected to the dimming shaft 62 in a threaded manner is formed on the inner wall of the first connection hole 611; the spring 631 is fitted in the first connection hole 611, the rear end of the spring 631 abuts against the screw portion 612, and the front end of the spring 631 abuts against the inner wall of the housing 1. The first connecting hole 611 is utilized to position the spring 631 in the embodiment; particularly, in the assembly stage, the spring 631 is first embedded in the first connecting hole 611 to keep the spring 631 in a set state, and then the tuning axis 62 is inserted into the first connecting hole 611 through the spring 631, and the rear end of the tuning axis 62 is screwed with the threaded portion 612; at the same time, the assembly of the dimming shaft 62 and the spring 631 is also achieved.

In the dimming process, the dimming shaft 62 drives the dimming transmission frame 61 to move in the front-rear direction, and the dimming transmission frame 61 drives the lower side wall of the reflector 2 to move in the front-rear direction; the cooperation of the two positioning shafts 21 on the reflector 2 and the two positioning grooves 11 is combined, so that the reflector 2 rotates around the positioning shafts 21 relative to the shell 1, and dimming is realized. In this embodiment, the dimming shaft 62 is a screw, and a sealing ring is installed between the limiting flange 621 of the dimming shaft 62 and the front end of the dimming protrusion 13.

As shown in fig. 13 and 14, the rear end of the positioning groove 11 in this embodiment is provided with an opening 111, and a fixing clip 112 is detachably mounted at the opening 111. Thus, in the assembly stage, the positioning shaft 21 is first inserted into the positioning groove 11 along the rear end of the positioning groove 11, i.e., the opening 111, and then the fixing clip 112 is mounted on the rear end of the positioning groove 11, so as to prevent the positioning shaft 21 from sliding out of the positioning groove 11. In this embodiment, the inner wall of the housing 1 is provided with a dimming positioning rib 15 protruding inwards and extending in the front-rear direction, and the dimming positioning rib 15 has elastic deformation capability. Each positioning groove 11 is located between two dimming positioning ribs 15, a gap at the rear ends of the two dimming positioning ribs 15 forms the opening 111, and locking protrusions 151 are disposed at the rear ends of the two dimming positioning ribs 15 and on opposite sides.
