[0032] The brightness of the headlight assembly in the related art is low, which affects driving safety. The inventors have found that the reason for this problem is that the current headlight assembly includes a light source and a lens arranged on the light-emitting side. The light emitted by the light source directly passes through the lens and is emitted. Some of the light at the edge is scattered and not effectively gathered, resulting in low brightness, which affects driving safety.

[0033] In response to the above problems, an embodiment of the present application provides a vehicle lamp assembly, in which a reflector is arranged between a first lens and a second lens, so that part of the light emitted by the light source can pass through the first lens and the second lens in sequence and then be emitted, and part of the light can pass through the first lens and illuminate the reflector, and be further reflected by the reflector to the first lens and then be emitted.

[0034] With such an arrangement, part of the light that passes through the first lens and shoots toward the edge is reflected by the reflector and can be gathered again by the second lens, thereby improving the effective utilization rate of light, enhancing the brightness of the ground and driving safety.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The vehicle provided in the embodiment of the present application may be an electric bicycle, an electric scooter, etc. The vehicle includes a vehicle body, a headlight assembly, a power source, etc. The headlight assembly is installed at the front end of the vehicle body along the forward direction of the vehicle. When the light in the driving environment of the vehicle is dark and affects the driving, the headlight assembly can be turned on to provide lighting.

[0037] It should be understood that the headlight assembly also includes a switch, which is used to control the turning on and off of the headlight assembly and adjust its brightness, etc. The headlight assembly is connected to a power source, and the power source can at least supply power to the headlight assembly. The power source can be a battery installed in the vehicle body, and the embodiments of the present application are not limited to this.

[0038] like Figure 1 and Figure 2 As shown, the vehicle lamp assembly 100 provided in the embodiment of the present application includes a first lens 10, a reflector 20, a light source 30 and a second lens 40, wherein along the light emitting direction of the light source 30, the first lens 10, the reflector 20 and the second lens 40 are sequentially arranged at intervals on one side of the light emitting light 30, and the first lens 10 covers the light source 30. After the light emitted by the light source 30 is irradiated to the first lens 10, part of the light is irradiated to the second lens 40, and part of the light is irradiated to the reflector 20.

[0039] Furthermore, in the embodiment of the present application, the first lens 10 and the second lens 40 are convex lenses, and the light irradiated to the light incident surface of the second lens 40 is emitted from the light exiting surface of the second lens 40 and converges toward the center. The materials for making the first lens 10 and the second lens 40 include but are not limited to resins and glass with good light transmittance, etc., and the embodiment of the present application is not limited to this.

[0040] In the embodiment of the present application, the light emitting direction of the light source 30 is usually consistent with the straight-line driving direction of the vehicle to ensure the lighting effect of the vehicle lamp assembly 100. The light source 30 is respectively arranged opposite to the first lens 10 and the second lens 40, and the reflector 20 is arranged between the first lens 10 and the second lens 40. For example, in the embodiment of the present application, the reflector 20 is respectively connected to the first lens 10 and the second lens 40; or, the reflector 20 is fixed on one side close to the first lens 10, and the other side of the reflector 20 is arranged close to the second lens 40, that is, the reflector 20 and the second lens 40 are installed with a gap between them.

[0041] Further, the reflector 20 is arranged around the light source 30, and part of the light emitted by the light source 30 is gathered by the first lens 10 and directly irradiated onto the second lens 40. Also, part of the light emitted by the light source 30 is emitted toward the reflector 20 through the first lens 10, and after being reflected by the reflector 20, it is transmitted toward the second lens 40 and irradiates the second lens 40. The second lens 40 is the outermost component of the vehicle lamp assembly 100, and the light emitted by the light source 30 is irradiated onto the second lens 40, and the light is gathered by the second lens 40 and irradiated onto the ground.

[0042] In the related art, the light source is directly projected onto the lens, and part of the light at the edge is dispersed and not effectively gathered, resulting in low brightness on the ground, which affects driving safety. However, the light assembly 100 provided in the embodiment of the present application reflects part of the light that passes through the first lens 10 and is directed to its edge or surroundings through the reflector 20, and can be gathered again by the second lens 40.

[0043] In other words, the vehicle lamp assembly provided in the embodiment of the present application can gather part of the light that is emitted to the surrounding area after passing through the first lens 10 and illuminate the ground again, so as to avoid the situation where this part of the light is diffused and cannot be effectively utilized. Such a configuration can improve the effective utilization rate of light, thereby improving the brightness of the ground and driving safety.

[0044] On the basis of the above-mentioned embodiment, the reflector 20 provided in the embodiment of the present application includes a cover body (not shown in the figure), which can be a truncated cone shell or a frustum shell, and the cover body includes a large diameter end and a small diameter end arranged opposite to each other, and the small diameter end and the large diameter end are respectively provided with through holes or openings. The light source 30 is arranged near the through hole at the small diameter end, and the light emitted by the light source 30 can sequentially pass through the through hole at the small diameter end and the through hole at the large diameter end to irradiate the second lens 40.

[0045] It is understandable that the inner wall of the cover body forms a reflective surface and can reflect the light irradiated to the inner wall thereof, and the reflected light can be irradiated to the second lens 40 through the through hole at the large diameter end.

[0046] For example, when the cover body provided in the embodiment of the present application is a frustum shell, the inner surface of the cover body is a curved surface with a uniform curvature. Alternatively, when the cover body provided in the embodiment of the present application is a partial pyramid shell, the inner surface of the cover body is a plane. Preferably, the inner surface of the cover body is a curved surface with a uniform curvature, and the embodiment of the present application is described using this as an example.

[0047] like Figure 3 As shown, in order to enhance the light gathering effect, the inner surface of a portion of the reflector 20 is configured as an arc-shaped surface protruding toward the second lens 40, so that after the light from the light source 30 is irradiated onto the arc-shaped surface, the reflected light is irradiated toward the central area of ​​the second lens 40, so as to enhance the gathering effect of the portion of light, thereby enhancing the ground brightness of the lamp assembly 100.

[0048] For example, the inner surface of the reflector 20 provided in the embodiment of the present application includes a first curved surface 21 and a second curved surface 22, wherein the first curved surface 21 is connected to the second curved surface 22 along the axial direction of the reflector 20. The second curved surface 22 is configured to bulge toward the second lens 40, and the first curved surface 21 and the second curved surface 22 have different curvatures. This arrangement allows part of the light from the light source 30 to irradiate the second curved surface 22, and the reflected light is irradiated toward the central area of ​​the second lens 40.

[0049] The first lens 10 and the second lens 40 provided in the embodiment of the present application form a double lens structure. The first lens 10 is arranged close to the light source 30 and its outer size is smaller than the second lens 40. Such an arrangement is conducive to the miniaturization design of the vehicle lamp assembly 100.

[0050] Specifically, the first lens 10 is disposed at the small diameter end of the reflector 20. Along the light emitting direction of the light source 30, the first lens 10 is disposed on the side of the light source 30 facing the second lens 40, and the first lens 10 is respectively opposite to the second lens 40 and the light source 30. For example, the first lens 10 can be disposed in the through hole at the small diameter end of the reflector 20, and in order to ensure the light emitting effect of the first lens 10, the light emitting surface of the first lens 10 protrudes from the through hole, so that the light emitting surface of the first lens 10 is exposed inside the cover.

[0051] It should be noted that the cover body of the reflector 20 provided in the embodiment of the present application can be made of a reflective material with high reflectivity, that is, the cover body itself has the ability to reflect light, and when the light from the light source 30 is irradiated to the inner surface of the cover body, it can further reflect the light.

[0052] In another embodiment, the inner surface of the cover is provided with a reflective layer, which can be an aluminum foil or other reflective film provided on the inner surface of the cover. For example, in the embodiment of the present application, the inner surface of the cover can be aluminum-plated to form an aluminum foil. In this way, the cover can be made of ordinary resin material or plastic material.

[0053] On this basis, the cover body and the first lens 10 can be configured as an integrated structure. For example, the cover body of the reflector 20 and the first lens 10 are both made of resin material, so that the first lens 10 is formed on the cover body, and then a reflective layer is formed on the surface of the cover body. Such a configuration can simplify the assembly process of the vehicle lamp assembly 100 and improve installation efficiency.

[0054] Furthermore, the vehicle lamp assembly 100 provided in the embodiment of the present application further includes a circuit board 50, which provides a mounting position for the light source 30. Exemplarily, the light source 30 is disposed on the circuit board 50, and the circuit board 50 is provided with a control circuit and / or a power supply circuit, wherein the power supply circuit is electrically connected to a power supply of the vehicle to supply power to the light source 30 through the power supply circuit.

[0055] It is understandable that the power supply circuit is also provided with a voltage adjustment module and / or a current adjustment module as needed to adjust the supply voltage and / or supply current to ensure stable power supply to the light source 30. The control circuit can be coupled with the power supply circuit, and the control switch of the vehicle is electrically connected to the control circuit, and the on / off and brightness of the light source 30 can be controlled by triggering the control switch. This implementation scheme can be set with reference to conventional technology in the art, and will not be repeated here.

[0056] Furthermore, the light source 30 can be an LED lamp, which has the characteristics of high luminous brightness and low power. Therefore, the vehicle lamp assembly 100 provided in the embodiment of the present application can improve the ground illumination brightness of the vehicle lamp assembly 100 without changing or even reducing energy consumption, thereby achieving a high-brightness illumination effect.

[0057] The circuit board 50 provided in the embodiment of the present application can be used as a substrate of the entire vehicle lamp assembly 100, and the vehicle lamp assembly 100 can be mounted to the front end of the vehicle body through the substrate. For example, in one embodiment, the cover of the reflector 20 is made integrally with the first lens 10, one side of the reflector 20 is connected to the second lens 40 and supports the second lens 40; the side of the reflector 20 away from the second lens 40 is connected to the circuit board 50.

[0058] Alternatively, in another embodiment, one side of the reflector 20 is connected to the second lens 40 and supports the second lens 40. The side of the reflector 20 away from the second lens 40 is connected to the first lens 10, and the first lens 10 is connected to the circuit board 50, so that the vehicle lamp assembly 100 is installed on the circuit board 50 and connected to the vehicle body through the circuit board 50. In this way, after the vehicle lamp assembly 100 is assembled, it can be installed on the vehicle body through the circuit board 50, which can improve the installation efficiency.
