[0032] Automobile headlights are devices installed on both sides of the head of the car for illuminating the road at night, and the high and low beam integrated lens is an important component of automobile headlights.

[0033] To reduce glare for oncoming drivers, low-beam headlights are often designed with a structure to create a cutoff line. For example, a folding element is installed inside the headlight to create a cutoff line in the illumination beam. However, this requires a moving mechanism to actuate the position of the folding element, making these headlights thicker, heavier, and more complex to manufacture.

[0034] Another method for creating a cutoff line in a headlamp involves using a reflector to reflect light from a light source, creating an illumination beam. A cutoff contour is provided at the bottom of the reflector, creating a cutoff at the rear edge of the reflective surface. While this method does not require a folding member or other type of obstruction to create a cutoff in the light, the resulting cutoff line lacks clarity.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a high and low beam integrated lens according to an embodiment of the present invention includes a fixing member 100 , a light source assembly 200 , a reflective assembly 300 and a lens 400 .

[0036] A mounting plane is provided on the surface of the fixing member 100 , and a light-proof cut-off portion 110 is provided on the mounting plane; the light source assembly 200 is arranged on the mounting plane.

[0037] The cut-off portion 110 can be made of the same material as the fixing member 100. The cut-off portion 110 is opaque and is used to block light, specifically to cut out a light outline. Of course, the light cut by the cut-off portion 110 is the light reflected by the reflective assembly 300.

[0038] One end of the reflective component 300 is spaced apart from the mounting plane, and the other end of the reflective component 300 extends to the mounting plane. The light source component 200 is located in the area enclosed by the reflective component 300 and the mounting plane. The reflective component 300 is configured to reflect the light emitted by the light source component 200. On the projection plane perpendicular to the light reflected by the reflective component 300, the projection of the cutoff portion 110 partially overlaps with the light reflected by the reflective component 300.

[0039] In an embodiment, the light emitting direction of the light source assembly 200 is set to be toward the reflective surface of the reflective assembly 300. The reflective surface of the reflective assembly 300 is preferably an arc-shaped surface, and the arc-shaped reflective surface can adjust the point light emitted by the light source assembly 200 to approximately parallel light. When the light reflected by the reflective assembly 300 passes through the cutoff portion 110, part of the light is blocked by the cutoff portion 110. It should be understood that the partial light being blocked here does not take into account the amount of blocked light, but is used to distinguish the state of the light, such as the three states of complete blocking, complete non-blocking and partial blocking of the light. The projection of the cutoff portion 110 partially overlaps with the light reflected by the reflective assembly 300, so that partial light blocking can be achieved.

[0040] The lens 400 is disposed on the optical path of the light reflected by the reflective component 300 , and the light reflected by the reflective component 300 first passes through the cut-off portion 110 and then passes through the lens 400 .

[0041] That is, the light reflected by the reflective assembly 300 is partially blocked by the cutoff portion 110 and then passes through the lens 400. The outline of the blocked light is magnified and imaged by the lens 400 to form a clear lighting cutoff line.

[0042] It is understandable that when the cut-off portion 110 and the fixing member 100 are made of the same material, preferably, the cut-off portion 110 and the fixing member 100 are an integrated structure.

[0043] Specifically, a blank with the outline of the cut-off portion 110 may be manufactured by casting, and then processed by material removal, such as milling, to obtain the fixing member 100 and the cut-off portion 110 in an integrated structure.

[0044] As a car headlight, the light source assembly 200 in the integrated high and low beam lens emits high brightness, the current passing through the circuit is large, and the heat generated is also large. In order to dissipate heat from the light source assembly 200 and ensure the service life of the light source assembly 200, it can be understood that the fixing part 100 is a radiator. Preferably, the fixing part 100 is a passive radiator.

[0045] While passive radiators offer less effective heat dissipation than active radiators, they are simpler in structure and take up less space. By adjusting the material and structure of the fixture 100, it can function as a passive radiator while also providing a mounting base for the light source assembly 200. The fixture 100 can be made of a metal with good thermal conductivity.

[0046] From a structural perspective, it can be understood that the fixing member 100 includes a base block 120 and a plurality of fins 130. A mounting plane is provided on one side surface of the base block 120, and a plurality of fins 130 are provided on the opposite side of the mounting plane. The fins 130 are parallel to each other and arranged at intervals.

[0047] The fins 130 can greatly increase the surface area of ​​the fixing member 100 and improve the heat exchange rate between the fixing member 100 and the air. The fins 130 can also be obtained by removing material, that is, the fins 130 and the base block 120 are also an integrated structure.

[0048] It is understandable that the light source assembly 200 includes a connecting plate 210 and multiple light sources 220 . The connecting plate 210 is attached to the installation plane. The multiple light sources 220 are arranged on the connecting plate 210 , and the emitted light of the light sources 220 is all directed toward the reflective assembly 300 .

[0049] The connecting plate 210 can also be directly made of a circuit board, and the light source 220 is soldered to the circuit board. The connecting plate 210 is generally a punched part. Since the mounting surface also has a cutoff portion 110, in order to avoid the cutoff portion 110, the connecting plate 210 is punched with a corresponding through hole. This allows the cutoff portion 110 to pass through the connecting plate 210 and be in the optical path of the light reflected by the reflective assembly 300 after the connecting plate 210 is attached to the mounting surface. Of course, in some specific structures, the cutoff portion 110 is located outside the connecting plate 210, that is, the cutoff portion 110 is not within the coverage area of ​​the connecting plate 210. In this case, the corresponding position of the connecting plate 210 does not need to be punched.

[0050] It should be understood that the punched through hole should be determined according to the outer contour of the cutoff portion 110 and can be a long strip or a square through hole. The cutoff portion 110 passes through the connecting plate 210 and also serves to position the connecting plate 210. Of course, the positioning here refers to the positioning of the connecting plate 210 when it is placed on the mounting surface. Specifically, the mounting surface is provided with threaded holes, and the connecting plate 210 is fixed to the mounting surface by screws passing through the connecting plate 210 and screwing into the threaded holes.

[0051] It can be understood that the multiple light sources 220 include a first light source and a second light source, each of which is at least provided with one, the first light source is configured to perform a low beam function, and the second light source is configured to perform a high beam function.

[0052] By adjusting the installation positions and light emission angles of the first and second light sources, and in conjunction with the reflector assembly 300, it is possible to distinguish between high beam and low beam. It should be understood that the biggest difference between high beam and low beam is that the angle between the emitted light of low beam and the horizontal plane is larger.

[0053] It can be understood that the reflective assembly 300 has a plurality of reflective surfaces, and each first light source and each second light source has an independent reflective surface.

[0054] For the low beam function performed by the first light source, the independent reflective surface can cooperate with the first light source to better achieve the low beam effect; for the high beam function performed by the second light source, the independent reflective surface can also cooperate with the second light source to better achieve the high beam effect.

[0055] It should be understood that, in some embodiments, a total of 11 light sources 220 are provided, of which 6 first light sources are provided for performing the low beam function, and 5 second light sources are provided for performing the high beam function.

[0056] It can be understood that the lens 400 is configured to magnify and image the light reflected by the reflective component 300 .

[0057] The light reflected by the reflective assembly 300 passes through the lens 400 to form a final high beam or low beam pattern.

[0058] It can be understood that the lens 400 includes a first mirror surface 410 and a second mirror surface 420 that are opposite to each other. The first mirror surface 410 is a convex surface, and the second mirror surface 420 is a convex surface.

[0059] An automobile according to an embodiment of the utility model comprises any one of the above-mentioned high and low beam integrated lenses.

[0060] Automobiles that use the above-mentioned integrated high and low beam lens as a headlight structure have a clearer lighting cutoff line, and the thickness of the headlight can be made thinner. In the integrated high and low beam lens structure, the light emitting direction of the light source assembly is set to be toward the reflective surface of the reflective assembly. The reflective surface of the reflective assembly is preferably an arc-shaped surface, and the arc-shaped reflective surface can adjust the point light emitted by the light source assembly into approximately parallel light. When the light reflected by the reflective assembly passes through the cutoff portion, part of the light is blocked by the cutoff portion. The projection of the cutoff portion partially overlaps with the light reflected by the reflective assembly, so that part of the light can be blocked. The lens is set on the optical path of the light reflected by the reflective assembly, and the light reflected by the reflective assembly first passes through the cutoff portion and then passes through the lens. That is, the light reflected by the reflective assembly is partially blocked by the cutoff portion and then passes through the lens. Among them, the outline generated by the blocked light is magnified and imaged by the lens, which can form a clear lighting cutoff line.

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
