[0030] Please refer to Figure 3 , Figure 3 Schematic diagram of a bracket 20 according to an embodiment of the present invention. As shown in the figure, the bracket 20 includes a frame portion 21 that buckles the lens 10 and a plurality of leg portions 22 that connect the reflective bowl 40; one end of the frame portion 21 has an inner extension portion 23 that stops against the lens 10 and a riveting portion 24 close to the inner extension portion 23, the inner extension portion 23 abuts against the outer edge of the lens 10, and the riveting portion 24 fastens the lens 10 by bending and buckling the pressing ring 30. In an embodiment of the present invention, the frame portion 21 uses the inner extension portion 23 to stop against the outer edge of the lens 10, and the pressing ring 30 is inserted thereafter, and the riveting portion 24 is bent by a riveting machine so that the riveting portion 24 buckles the pressing ring 30, thereby fixing the pressing ring 30 and the lens 10. The structure is simple, the processing is convenient, and the stability of the lens 10 is improved.

[0031] It is worth mentioning that in another embodiment, the pressing ring 30 is made of 65Mn, which has good elasticity and rigidity, and the outer diameter of the pressing ring 30 is larger than the inner diameter of the frame 21, and it has an opening 31.

[0032] Next, please refer to Figures 4 to 6 , Figure 4 is a schematic diagram of a dimming assembly 50 according to an embodiment of the present invention; Figure 5 is a schematic diagram of a low beam area A according to an embodiment of the present invention; Figure 6 Schematic diagram of high beam area B of an embodiment of the present invention. As shown in the figure, the dimming assembly 50 includes a light shielding plate 51 covering one side of the reflective bowl 40, and the light shielding plate 51 exposes the high beam area B; a solenoid valve 52 disposed on the light shielding plate 51; a dimming plate 53 connected to the solenoid valve 52, and the dimming plate 53 has a positioning hole 531 at one end, and a bending arm 532 on one side of the positioning hole 531, and the bending arm 532 is buckled on the valve stem 521 of the solenoid valve 52; a buckle plate 54 disposed at the other end of the dimming plate 53, and the buckle plate 54 The light shielding plate 51 is installed to form a sliding cavity 541 facing the dimming plate 53; and the shaft connecting rod 55 is installed on the light shielding plate 51 through the positioning hole 531; wherein, when the solenoid valve 52 is closed, the dimming plate 53 abuts against one side of the buckle plate 54, and cooperates with the light shielding plate 51 to expose the low beam area A; when the solenoid valve 52 is started, the valve stem 521 is extended, driving the dimming plate 53 to rotate around the shaft connecting rod 55, and the dimming plate 53 overlaps with the light shielding plate 51, exposing the high beam area B. In one embodiment of the present invention, the light shielding plate 51 is installed on the flange portion 41 of the reflective bowl 40, which is lower than the bulb 70, so as to suppress the light, prevent the light from scattering, increase the brightness of the illumination, and avoid unclear illumination. The positioning hole 531 of the dimming plate 53 is hinged on the shaft connecting rod 55 to realize the rotation driven by the solenoid valve 52, so that the other end of the dimming plate 53 can swing slightly, further covering or shrinking the illumination area, so as to realize the switching between high and low beams. The buckle plate 54 limits the rotation angle of the dimming plate 53 on the other side to prevent the dimming plate 53 from rotating too much and separating from the light blocking plate 51 to block the transmission of light, resulting in blurred vision, precise control and easy use.

[0033] When the solenoid valve 52 is not started, the valve stem 521 does not move, and the other end of the dimming plate 53 is stopped by the buckle plate 54, covering a certain area beyond the light blocking plate 51, while shielding a part of the bulb 70, thereby pressing against the light to achieve low beam illumination; when the solenoid valve 52 is started, the valve stem 521 contracts, driving the dimming plate 53 to rotate, so that the dimming plate 53 rotates back and overlaps with the light blocking plate 51, and cannot shield the illumination of the bulb 70, thereby achieving high beam control, flexible switching, and convenient control.

[0034] Please continue to refer to Figure 7 , Figure 7 Schematic diagram of the sleeve disc 56 of one embodiment of the present invention.

In one embodiment of the present invention, the dimming plate 53 is sleeved on the sleeve disc 56 to avoid friction and wear between the dimming plate 53 and the shaft connecting rod 55 during the driving process, thereby affecting the rotation efficiency. In the present invention, the dimming plate 53 is sleeved between the second sleeve portion 562 and the first sleeve portion 561 to form a good support for the first sleeve portion 561, thereby avoiding direct contact with the uneven baffle light 51 to affect the driving. In addition, an inner concave cone surface 564 is provided between the first sleeve portion 562 and the third sleeve portion 563 to reduce the vibration of the stepped shaft-shaped sleeve disc 56, thereby evacuating stress concentration and avoiding excessive vibration. The structure is simple and practical.
