When the motorcycle needs to turn, the driver will turn on the motorcycle turn signal in advance to let vehicles or pedestrians around the motorcycle know the turning direction of the motorcycle, thereby achieving the purpose of safe driving of the motorcycle. Existing motorcycle turn signals generally emit light in a single row, with a small light output area, which is not obvious when observed.

[0003] For example, the "A kind of motorcycle front turn signal lamp" disclosed in the Chinese patent document, with the announcement number CN207179547U, includes a base and a lamp holder installed on the base, wherein a reflective cup is arranged inside the lamp holder; a light emitter is installed inside the reflective cup; a lampshade is installed on the lamp holder; the interior of the lamp holder is arranged in a stepped shape and has at least two levels, each step is equipped with a reflective cup, and each reflective cup is correspondingly provided with a light emitter. The disadvantage of this patent is that several light emitters are arranged in the same row, and the light emitting area is small, which is not obvious when observed. Utility Model Content

[0004] The utility model aims to overcome the problem in the prior art that the motorcycle turn signal lamp has a small light emitting area and is not obvious enough when observed, and provides a front turn signal lamp structure with light emitting from top to bottom, which has a larger light emitting area and is more obvious when observed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The light board of the existing turn signal generally emits light directly facing the light emitting plate. This form will cause the light to be too concentrated and the uniformity is not good enough. In the present application, the light board on which the light source is installed is set between two reflecting plates, and the light source is guided to the upper light emitting part and the lower light emitting part by reflection, which not only increases the light emitting area but also improves the uniformity of the light.

[0008] Preferably, a concave cavity is provided between the upper light emitting portion and the lower light emitting portion. By providing the concave cavity, there is a gap between the upper light emitting portion and the lower light emitting portion. Firstly, since the light is diffuse after emitting from the light emitting surface, the two light emitting portions provided at intervals can further avoid light concentration and increase the light emitting area; secondly, the concave-convex structure can improve the structural strength of the front cover and avoid damage from collision.

[0009] Preferably, a light scattering structure is provided on the side of the reflector plate facing the front cover, and the light scattering structure includes an upper light scattering plate facing the upper reflector portion and a lower light scattering plate facing the lower reflector portion. The light scattering structure can further improve the uniformity of light output.

[0011] Preferably, the upper reflector includes a plurality of arcuate reflective surfaces corresponding to the side light sources on the light board, and the lower reflector includes a plurality of arcuate reflective surfaces corresponding to the side light sources below the light board. The arcuate reflective surfaces can reflect the vertically emitted light to the horizontal direction, so that the light board can be installed horizontally between the two reflective surfaces.

[0012] Preferably, the reflector is provided with a first light board slot, through which the light board can be limited and the installation of the light board is more convenient.

[0013] Preferably, the present application further comprises a rear cover, the reflector is fixedly connected to the rear cover, and a clamping structure is provided between the front cover and the rear cover.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Embodiment 1, as Figure 1-2 As shown, a front turn signal light structure with light emitting from top to bottom is a right front turn signal light used on a motorcycle. It comprises a front cover 1, a reflector 2, a light board 3, and a rear cover 4.

[0024] The front cover 1 includes an upper light emitting portion 5 and a lower light emitting portion 6. The upper light emitting portion 5 and the lower light emitting portion 6 protrude from the front side surface of the front cover 1. A concave cavity 7 is provided between the upper light emitting portion 5 and the lower light emitting portion 6. By providing the concave cavity 7, there is a gap between the upper light emitting portion 5 and the lower light emitting portion 6. Firstly, since the light is diffuse after being emitted from the light emitting surface, the two light emitting portions provided at intervals can further avoid light concentration and increase the light emitting area; secondly, the concave-convex structure can improve the structural strength of the front cover 1 and avoid damage from collision.

[0025] The side of the reflector 2 facing the front cover 1 is its front side, and the side opposite to the front side is the rear side. The front side of the reflector 2 is provided with an upper diffuser 10 opposite to the upper light emitting portion 5 and a lower diffuser 11 opposite to the lower light emitting portion 6. An upper reflector 8 and a lower reflector 9 are provided on the rear side of the reflector 2. The upper reflector 8 is opposite to the upper diffuser 10, and the lower reflector 9 is opposite to the lower diffuser 11. The lamp board 3 is installed between the upper reflector 8 and the lower reflector 9, and light sources are installed on both sides of the lamp board 3. The upper reflector 8 and the lower reflector 9 are upper and lower mirror-symmetrical structures, and the lamp board 3 is installed in the middle of the upper reflector 8 and the lower reflector 9.

[0026] A plurality of light sources are installed on both sides of the light board 3, and the plurality of light sources are arranged at equal intervals in the horizontal direction. The upper reflection part 8 includes a plurality of arc-shaped reflection surfaces corresponding to the upper side light sources of the light board 3, and the lower reflection part 9 includes a plurality of arc-shaped reflection surfaces corresponding to the lower side light sources of the light board 3. The plurality of arc-shaped reflection surfaces are distributed in a stepped manner.

[0027] A boss 12 is also provided on the front side of the reflector 2, and a reflector stopper is provided on the front cover 1, wherein a boss mounting groove matching the shape of the boss 12 is provided in the reflector stopper. This structure not only limits the reflector 2 and the front cover 1 relative to each other, but also improves the structural strength of the front cover 1 through the support of the boss 12, so that it is not easily damaged by collision.

[0028] The light board 3 of the existing turn signal generally emits light facing the light emitting plate. This form will cause the light to be too concentrated and the uniformity of the light to be insufficient. In the present application, the light board 3 on which the light source is installed is arranged between the two reflective plates 2, and the light source is guided to the upper light emitting portion 5 and the lower light emitting portion 6 by reflection, which not only increases the light emitting area, but also improves the uniformity of the light emitting. The light emitting uniformity can be further improved by the light diffusion structure. By arranging multiple light sources at intervals in the horizontal direction, the uniformity of the light emitting surface in the horizontal direction can be improved and the size of the light emitting area in the horizontal direction can be increased. The vertically emitted light can be reflected to the horizontal direction by the arc-shaped reflective surface, so that the light board 3 can be installed horizontally between the two reflective portions.

[0029] The reflector 2 is provided with a first light board slot 13 in the direction toward the light board 3. The first light board slot 13 is arranged on the first light board connector. The first light board connector is fixed between the upper reflector 8 and the lower reflector 9. The first light board connector includes an upper limit portion and a lower limit portion, and a bayonet is formed between the upper limit portion and the lower limit portion. The light board 3 can be limited by this structure, and the installation of the light board 3 is more convenient. There are two first light board connectors in the reflector 2, and the two light board connectors are spaced apart from each other, thereby further improving the limiting effect of the light board 3. The rear cover 4 is provided with a second light board slot 14 on the side facing the light board 3. The second light board slot 14 is arranged on the second light board connector. The second light board connector and the rear cover 4 are fixedly fixed by reinforcing ribs. The second light board connector also includes an upper limit portion and a lower limit portion, and a bayonet is formed between the upper limit portion and the lower limit portion. The structure can also limit the position of the light board 3, and make the installation of the light board 3 more convenient. In this embodiment, the number of the second light board connector in the rear cover 4 is one, and in other possible implementations, the number of the second light board connector can also be multiple.

[0030] The reflector 2 is fixedly connected to the rear cover 4, and a threaded hole structure 15 is respectively provided on the left and right sides of the rear cover 4. A countersunk hole corresponding to the threaded hole is respectively provided on the left and right sides of the reflector 2. The reflector 2 and the rear cover 4 can be fixedly connected together by bolts passing through the countersunk holes. After the reflector 2 and the rear cover 4 are fixedly connected, the light board 3 is fixed between the reflector 2 and the rear cover 4, and is completely limited by the first light board slot 13 and the second light board slot 14.

[0031] A clamping structure is provided between the front cover 1 and the rear cover 4. The lamp panel 3 can be enclosed by the rear cover 4, and the indirect connection between the reflector 2 and the front cover 1 is realized at the same time. A clamping block 16 is provided on the front cover 1, and an annular covering surface 18 is provided on the rear cover 4. A clamping interface 17 adapted to the clamping block 16 is provided on the covering surface 18. The covering surface 18 is thin-walled, which makes it have a certain elasticity. The clamping block 16 is a wedge-shaped structure, and a guide slope is provided on the side facing the rear cover 4. The guide slope can make the front cover 1 and the rear cover 4 can be directly inserted during installation, and it is not easy to fall out after installation. That is to say, during the installation of the front cover 1 and the rear cover 4, the covering surface 18 is deformed and opened to both sides by the guidance of the guide slope, so that the clamping block 16 enters the clamping interface 17. After the clamping block 16 enters the clamping interface 17, the covering surface 18 is reset under the action of elasticity, so that the front cover 1 and the rear cover 4 are relatively fixed. The front cover 1 and the rear cover 4 can be installed more quickly by means of the clamping block 16 and the clamping interface 17. After the front cover 1 and the rear cover 4 are fixed, the relative positions of the various components of the entire turn signal lamp are determined. In this embodiment, the number of the clamping structures is three, which are respectively arranged on the upper side, the lower side, and one of the left and right sides. In other possible embodiments, the number of the clamping structures can also be two or more than three.

A concave cavity 7 is provided between the upper light emitting portion 5 and the lower light emitting portion 6. By providing the concave cavity 7, there is a gap between the upper light emitting portion 5 and the lower light emitting portion 6. Firstly, since the light is diffuse after being emitted from the light emitting surface, the two light emitting portions provided at intervals can further avoid light concentration and increase the light emitting area; secondly, the concave-convex structure can improve the structural strength of the front cover 1 and avoid damage from collision.

[0034] The side of the reflector 2 facing the front cover 1 is its front side, and the side opposite to the front side is the rear side.

[0037] The light board 3 of the existing turn signal generally emits light facing the light emitting plate. This form will cause the light to be too concentrated and the uniformity of the light to be insufficient. In the present application, the light board 3 on which the light source is installed is arranged between the two reflective plates 2, and the light source is guided to the upper light emitting portion 5 and the lower light emitting portion 6 by reflection, which not only increases the light emitting area, but also improves the uniformity of the light emitting. The light emitting uniformity can be further improved by the light diffusion structure. By arranging multiple light sources at intervals in the horizontal direction, the uniformity of the light emitting surface in the horizontal direction can be improved and the size of the light emitting area in the horizontal direction can be increased. The vertically emitted light can be reflected to the horizontal direction by the arc-shaped reflective surface, so that the light board 3 can be installed horizontally between the two reflective portions.

The rear cover 4 is provided with a second light board slot 14 on the side facing the light board 3. The second light board slot 14 is arranged on the second light board connector. The second light board connector and the rear cover 4 are fixedly fixed by reinforcing ribs. The second light board connector also includes an upper limit portion and a lower limit portion, and a bayonet is formed between the upper limit portion and the lower limit portion.
