Description
Technical Field
[0001] The utility model relates to the technical field of motorcycle lamps, in particular to a headlamp with a dimming mechanism and a vehicle. Background Art
[0002] Motorcycle headlights are an important guarantee for safe driving of motorcycles, and the design and manufacture of headlights are crucial. Headlights usually include lamp housings, radiators, reflectors, lens holders, lenses, decorative parts, position lights, decorative rings, and lampshades. The combination of position lights and headlights makes motorcycle headlights low-cost and small in space. The function of the lampshade is to protect the internal components while allowing light to pass through. In the field of optical design, the refraction and reflection of light are key technical points. Through reasonable design, light can be propagated in the expected direction, thereby achieving good lighting effects. There are usually two ways to implement headlights: (1) Arrange the headlight beads and position light beads separately on the internal PCB board and diffuse them through the lampshade. This structure saves costs, but the brightness of the light is not enough and the illumination distance is not enough; (2) Use two PCB boards, one for lighting the headlight beads and the other for lighting the position light beads, and both use external lenses or thick walls for refraction, and then diffuse the light through the lampshade. Although this structure increases costs and makes the space more compact, the light can be refracted through the external lens or thick walls to illuminate a longer distance and is safer. As the regulations on motorcycle lights are improved, the second method is becoming more and more the mainstream design. Among them, the requirements for light beam illumination are: in the unloaded vehicle state, the low beam of the car or motorcycle headlight is illuminated on the screen at a distance of 10m. The vertical position of the angle or midpoint of the light-dark cut-off line of the low beam, for motor vehicles with a height of the center of the low beam light-transmitting surface (reference center, the same below) less than or equal to 1000mm, should not be higher than the straight line 50mm below the horizontal plane where the center of the low beam light-transmitting surface is located, and should not be lower than the straight line 300mm below the horizontal plane where the center of the low beam light-transmitting surface is located; for motor vehicles with a height of the center of the low beam light-transmitting surface greater than 1000mm, it should not be higher than the straight line 100mm below the horizontal plane where the center of the low beam light-transmitting surface is located, and should not be lower than the straight line 350mm below the horizontal plane where the center of the low beam light-transmitting surface is located. Except for three-wheeled vehicles and motorcycles equipped with one headlamp, the horizontal position of the cut-off angle or midpoint of the low beam of the headlamp should be less than or equal to 170 mm to the left and less than or equal to 350 mm to the right compared with the treatment plane where the center of the light transmission surface of the low beam is located.
[0003] Therefore, in order to prevent the low beam from being too high or too low after installation, the prior art usually considers adding an adjustment mechanism to the headlamp so that it has an adjustment range of 3° up and down to align the irradiation position. However, this solution increases the size of the device due to the addition of the adjustment mechanism, which poses a new challenge to the miniaturization of motorcycle headlamps. In addition, the dimming mechanism and the thick wall of the position lamp will also have a certain impact on the uniformity of the light pattern. Utility Model Content
[0004] (I) Technical problems to be solved: In view of the shortcomings of the prior art that a motorcycle headlamp combines a dimming mechanism and a thick wall of a position light, resulting in a large volume and also having a certain impact on the uniformity of the light pattern, this utility model provides a method for changing the installation position of the thick wall of the position light by modifying the shape of the lampshade, thereby reducing the volume of the headlamp and making the light of the headlamp uniform.
[0005] (II) Technical solution: To achieve the above-mentioned purpose, the utility model provides the following technical solution: A headlamp with a dimming mechanism, comprising: a lampshade, wherein the lampshade and the lamp housing constitute the outer contour of the entire position lamp, and wherein: a decorative ring is installed inside the lampshade, the interior of the decorative ring is hollowed out, a lens opening is formed at the hollowed-out part, decorative parts and lenses are sequentially nested inside the lens opening, a spacing is designed between the inner wall of the decorative ring and the wall of the decorative part to form a dimming space, a position lamp thick wall is installed below the lens opening, the position lamp thick wall is embedded in the through hole at the lower part of the decorative ring, and the decorative ring as a whole is a diamond structure inclined outward from the bottom.
[0006] Preferably, the edges of the outer surface of the lampshade are all arc-shaped, and the outer surface of the decorative ring is designed with a circle of ribs facing outwards.
[0007] Preferably, a decorative piece is nested and installed in the middle of the lens opening, a lens is installed inside the decorative piece, a lens holder is fixedly connected to the rear of the lens, a radiator is designed behind the lens holder, there is a gap between the radiator and the lens holder, a reflector and a light-emitting lamp are installed in the gap, a lamp housing is behind the radiator, and the lamp housing is connected to the lampshade.
[0008] Preferably, the lens opening is 2 mm lower than the upper edge of the decorative ring.
[0009] Preferably, a dimming mechanism is connected and installed at the rear of the radiator, and the dimming mechanism has a degree of freedom of movement of not less than 3° in the up and down directions.
[0010] Preferably, the lampshade and the lamp housing are sealed and connected by applying hot melt adhesive.
[0011] Preferably, the lampshade and the lamp housing are made of high temperature resistant material.
[0012] Preferably, the lampshade has a diamond-shaped structure with a protrusion at the bottom.
[0013] Beneficial effects: 1. The headlamp with a dimming mechanism has a decorative ring that is a diamond-shaped structure protruding from below. The thick wall of the position lamp is embedded in the lower part of the decorative ring, and there is a dimming space between the decorative ring and the decorative part. The module composed of the decorative part, the lens and the lens bracket has a degree of freedom of movement of not less than 3° in the vertical direction in the dimming space. The existing motorcycle headlamp combines the dimming mechanism and the thick wall of the position lamp, resulting in a large volume, and the conventional dimming mechanism has a degree of freedom of movement of 3° in the vertical direction inside the headlamp. The utility model installs the thick wall of the position lamp inside the decorative ring, so that the dimming mechanism does not interfere with the thick wall of the position lamp when adjusting the high and low light module, avoiding collision and solving the problem of the large volume of the headlamp.
[0014] 2. The headlamp with a dimming mechanism has arc-shaped edges on the outer surface of the lampshade. When the motorcycle headlamp is turned on, the light emitted from the light source is refracted after passing through the lens and radiates forward. When passing through the right-angled fold of the outer contour of the lampshade, the light will be refracted multiple times or blocked, resulting in the light being unable to be projected out. In the light pattern, there are two dark lines projected on both sides, making the light pattern uneven. To address this problem, the utility model cancels the right-angled fold of the lampshade, so that the lampshade is formed into a certain arc, so that the light can be refracted normally after passing through the arc, thereby improving the uniformity of the light pattern.
[0015] 3. The headlamp with a dimming mechanism has a circle of ribs designed outward on the outer surface of the decorative ring. Since the utility model changes the edge of the outer surface of the lampshade from a right angle to an arc, a part of the width is sacrificed, which may lead to an unstable structure of the headlamp. For this reason, we designed and installed a circle of ribs outward on the outer side of the decorative ring, and optimized the structure of the headlamp, which can not only completely block the light pattern of the dark line on the outside, but also further improve the uniformity of the light pattern, and at the same time avoid the problem that the structural strength of the lampshade may be affected by the cancellation of the folded edge.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.
[0024] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.
[0025] See also Figure 1-5 A headlamp with a dimming mechanism comprises: a lampshade 1, wherein the lampshade 1 and a lamp housing 9 constitute the outer contour of the entire position lamp, and is characterized in that: the outer surface edges of the lampshade 1 are all arc-shaped, the outer surface of the decorative ring 2 is designed with a circle of ribs outward, the lampshade 1 is installed with the decorative ring 2, the interior of the decorative ring 2 is hollowed out, and a lens opening 10 is formed at the hollowed-out part, the lens opening 10 is 2 mm lower than the upper edge of the decorative ring 2, a decorative piece 4 is nested and installed in the middle of the lens opening 10, a lens 5 is installed inside the decorative piece 4, a lens bracket 6 is fixedly connected to the rear of the lens 5, a radiator 8 is designed to be arranged behind the lens bracket 6, a dimming mechanism 11 is connected and installed to the rear of the radiator 8, and the dimming mechanism 11 There is no less than 3° freedom of movement in the up and down directions. There is a gap between the radiator 8 and the lens bracket 6, and a reflector 7 and a light-emitting lamp are installed in the gap. Behind the radiator 8 is a lamp housing 9. The lampshade 1 and the lamp housing 9 are sealed and connected by hot-melt adhesive, and both are made of high-temperature resistant materials. The decorative parts 4 and the lens 5 are nested and installed in sequence inside the lens opening 10. A spacing is designed between the inner wall of the decorative ring 2 and the outer wall of the decorative part 4 to form a dimming space 12. A position light thick wall 3 is installed below the lens opening 10, and the position light thick wall 3 is embedded in the through hole at the bottom of the decorative ring 2. The decorative ring 2 as a whole is a rhombus structure inclined outward from the bottom, and the lampshade 1 presents a rhombus structure protruding from the bottom.
[0026] like Figure 1-5As shown, the headlamp with a dimming mechanism has a diamond structure when the lamp is viewed from the side. The position light thick wall 3 is embedded in the lower part of the decorative ring 2, and there is a dimming space 12 between the decorative ring 2 and the decorative part 4, which is formed by the position light thick wall 3 and the high and low beam modules being staggered up and down. The module composed of the decorative part 4, the lens 5 and the lens bracket 6 has a degree of freedom of movement of not less than 3° in the vertical direction in the dimming space 12. The existing motorcycle headlamp combines the dimming mechanism and the position light thick wall, resulting in an excessively large volume, and the conventional dimming mechanism has a degree of freedom of movement of 3° in the vertical direction inside the headlamp. The utility model designs and installs the position light thick wall 3 inside the decorative ring 2, so that the dimming mechanism 11 does not interfere with the position light thick wall 3 when adjusting the high and low beam modules, thereby avoiding collisions and solving the problem of excessive volume of the headlamp.
[0027] like Figure 4 As shown, the headlamp with a dimming mechanism has arc-shaped edges on the outer surface of the lampshade 1. When the existing motorcycle headlamp is turned on, the light emitted from the light source is refracted after passing through the lens and radiates forward. When passing through the right-angle folded edge of the outer contour of the lampshade, the light will be refracted multiple times or blocked, resulting in the light being unable to be projected out. In the light pattern, there are two dark lines projected on the sides, making the light pattern uneven. There are two solutions to this problem in the prior art. One is to add a circle of ribs outwards of the decorative ring so that the dark lines on the outside of the light pattern are completely blocked to make the light pattern uniform; the other is to cancel the folded edge so that the lampshade is formed into a certain arc, and the light can be refracted normally after passing through the arc. Compared with the prior art, the light pattern is made uniform by adding ribs, but the widening method is sacrificed. While ensuring the uniformity of the light pattern, the widening is not sacrificed, thereby improving the lighting effect; and for the solution of canceling the folded edge, although the problem of uneven light pattern can be solved, the structural strength of the lampshade may be affected. The present invention adds a circle of ribs outwardly of the decorative ring 2, which can not only make the light pattern uniform, but also enhance the structural strength of the lampshade 1, thereby avoiding the need for additional reinforcement design.
[0028] like Figure 2 As shown, in the headlamp with dimming mechanism, a circle of ribs is designed outwardly on the outer surface of the decorative ring 2. Since the edge of the outer surface of the lampshade 1 is changed from a right angle to an arc in the utility model, a part of the width is sacrificed, which may lead to the instability of the headlamp structure. Therefore, we designed and installed a circle of ribs outwardly on the outer side of the decorative ring 2, and optimized the structure of the headlamp, which can not only completely block the light pattern of the dark line near the outer side, but also further improve the uniformity of the light pattern, and at the same time avoid the problem that the structural strength of the lampshade 1 may be affected by the cancellation of the folded edge.
[0029] In use, since the utility model adopts a lampshade 1 design embodiment without right-angle folding edges: a lampshade 1 of a headlight is designed, and the right-angle folding edges are eliminated, so that the lampshade 1 is formed into a certain arc shape. Through this design, the light can be refracted normally after passing through the lampshade 1, improving the uniformity of the light pattern and avoiding the problem of multiple refractions or blocking of the light.

The present patent also includes a vehicle using the headlamp with a dimming mechanism, as long as the front of the vehicle is designed with an assembly module, and the assembly module is fixedly assembled with the rear of the lamp housing 9, then the vehicle also falls within the scope of protection of the present invention.
