Description

Technical Field

[0001] The present invention relates to the technical field of automotive headlights, and particularly to a headlight module and a headlight. Background Art

[0002] In existing headlight modules, generally, an ellipsoidal or quasi-ellipsoidal reflector is used to converge the light emitted by a light source disposed at the near focus of the ellipsoid or quasi-ellipsoid to the far focus of the ellipsoid or quasi-ellipsoid. The far focus of the ellipsoid or quasi-ellipsoid is set at the focus of a convex lens, that is, the convex lens is used to image the light spot formed at the focus of the convex lens. However, this results in a large front-to-back dimension of the headlight module and cannot meet the requirements of flattening the headlight and reducing the occupied space. Summary of the Invention

[0003] The purpose of the present invention is to overcome the problem of large occupied space of the existing headlight module, and provide a headlight module with the advantages of small occupied space and convenient use.

[0004] To achieve the above purpose, on the one hand, the present invention provides a headlight module, including a low-beam module, a high-beam module, and an output lens. The low-beam module and the high-beam module are located on the same side of the output lens and are arranged vertically. The low-beam module includes a low-beam light source and a low-beam bending assembly, and the high-beam module includes a high-beam light source and a high-beam bending assembly. The low-beam bending assembly and the high-beam bending assembly are arranged between the low-beam light source and the high-beam light source in the vertical direction. After the light emitted by the low-beam light source and the high-beam light source is reflected by the low-beam bending assembly and the high-beam bending assembly respectively, it enters the output lens through the same incident surface of the output lens, and exits from the same output surface of the output lens and projects to form the required low-beam light pattern and high-beam light pattern respectively.

[0005] In some embodiments, the low-beam bending assembly includes a low-beam reflection structure and a low-beam bending structure arranged vertically. The low-beam reflection structure is arranged adjacent to the low-beam light source so that the light emitted by the low-beam light source can be reflected by the low-beam reflection structure and reflected towards the low-beam bending structure, and then reflected by the low-beam bending structure and projected towards the output lens;

[0006] The high-beam bending assembly includes a high-beam reflection structure and a high-beam bending structure arranged vertically. The high-beam reflection structure is arranged adjacent to the high-beam light source so that the light emitted by the high-beam light source can be reflected by the high-beam reflection structure and reflected towards the high-beam bending structure, and then reflected by the high-beam bending structure and projected towards the output lens.

[0007] In some embodiments, the low-beam reflection structure includes a low-beam reflection surface, and the low-beam bending structure includes a low-beam bending reflection surface. The low-beam reflection surface and the low-beam bending reflection surface are arranged vertically. The light emitted by the low-beam light source is reflected by the low-beam reflection surface and then projected towards the low-beam bending reflection surface, and then reflected by the low-beam bending reflection surface and projected towards the output lens.

[0008] In some embodiments, the low beam bending structure also includes a low beam bending light entrance surface and a low beam bending light exit surface. The light reflected by the low beam reflection structure enters the low beam bending structure from the low beam bending light entrance surface, and after being reflected by the low beam bending reflection surface, it is emitted from the low beam bending light exit surface to the light exit lens.

[0009] In some embodiments, the low beam cut-off line structure of the low beam module is located at a boundary position of the low beam reflection structure close to the low beam light source.

[0010] In some embodiments, the low beam reflective structure and the low beam bending structure are integrated into one piece.

[0011] In some embodiments, the high beam reflection structure includes a high beam reflection surface, and the high beam bending structure includes a high beam bending reflection surface. The high beam reflection surface and the high beam bending reflection surface are arranged vertically. The light emitted by the high beam light source is reflected by the high beam reflection surface and then emitted toward the high beam bending reflection surface, and then reflected by the high beam bending reflection surface and then emitted toward the light output lens.

[0012] In some embodiments, the high beam bending structure also includes a high beam bending light incident surface and a high beam bending light output surface. The light reflected by the high beam reflection structure enters the high beam bending structure from the high beam bending light incident surface, is reflected by the high beam bending reflection surface, and then is emitted from the high beam bending light output surface to the light output lens.

[0013] In some embodiments, the high beam reflection structure and the high beam bending structure are integrated into one piece.

[0014] In some embodiments, a circuit board is also included. The circuit board is arranged between the light output lens and the low beam module and the high beam module. The low beam module and the high beam module are arranged on one side of the circuit board, and a heat dissipation structure is arranged on the other side.

[0015] In some embodiments, the middle area of ​​the circuit board is set as an opening, and the outgoing light of the low beam module and the high beam module is suitable for passing through the opening to the light output lens.

[0016] A second aspect of the present invention provides a vehicle lamp, comprising the above-mentioned vehicle lamp module.

[0017] Through the above technical solution, the light rays emitted by the low beam light source and the high beam light source of the present application finally enter the same light incident surface of the light emitting lens and are emitted from the same light emitting surface of the light emitting lens. There is no need to distinguish between the high beam light incident surface and the low beam light incident surface of the light emitting lens. For the integrated high and low beam module, in the low beam mode, the entire light emitting lens can be lit, and there is no need to additionally increase the cost and structural design for the high beam accompanying lighting effect in the low beam mode (the high beam accompanying lighting effect refers to the effect that the lens corresponding to the high beam module can also be lit in the low beam mode). A better appearance of the vehicle headlight lighting can also be obtained. At the same time, during the process of the low beam module and the high beam module emitting light rays, the low beam bending component and the high beam bending component can deflect the transmission optical paths of the low beam light rays and the high beam light rays. Specifically, for the original low beam module and high beam module, part of the optical paths in the front-back direction are deflected by the low beam bending component and the high beam bending component and converted to other directions, shortening the transmission optical paths of the low beam light rays and the high beam light rays in the front-back direction while realizing the low beam light emission and the high beam light emission. The low beam bending component and the high beam bending component effectively reduce the front-back size of the vehicle headlight module and achieve the flattening of the vehicle headlight module.

[0030] All terms used in the present application have the same meaning as understood by those of ordinary skill in the art to which the present application belongs, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as those, should be construed as having a meaning consistent with their meaning in the context of the relevant art, and should not be construed in an idealized or overly formal sense, unless specifically defined as such here.

[0031] For technologies, methods and devices known to those of ordinary skill in the relevant art, they may not be discussed in detail, but in appropriate cases, the technologies, methods and devices should be regarded as part of the specification.

[0032] Refer to Figure 1 and Figure 4, this application discloses a vehicle headlight module, which includes a low beam module 1, a high beam module 2, and an output lens 3. The low beam module 1 and the high beam module 2 are located on the same side of the output lens 3 and are arranged vertically. The low beam module 1 includes a low beam light source 4 and a low beam bending component 5, and the high beam module 2 includes a high beam light source 6 and a high beam bending component 7. The low beam bending component 5 and the high beam bending component 7 are arranged between the low beam light source 4 and the high beam light source 6 in the vertical direction. After the light rays emitted by the low beam light source 4 and the high beam light source 6 are reflected by the low beam bending component 5 and the high beam bending component 7 respectively, they enter the output lens 3 through the same incident surface of the output lens 3, and are emitted from the same output surface of the output lens 3 and respectively project to form the required low beam light pattern and high beam light pattern.

[0033] A vehicle headlight module disclosed in this application includes an output lens 3. A low beam module 1 and a high beam module 2 arranged vertically are provided on the side where the incident surface of the output lens 3 is located. The light rays emitted by the low beam light source 4 and the high beam light source 6 finally enter the same incident surface of the output lens 3 and are emitted from the same output surface of the output lens 3. The output lens 3 can be lit in both the low beam mode and the high beam mode. This application does not need to distinguish between the high beam incident surface and the low beam incident surface of the output lens 3. For a combined high and low beam module, in the low beam mode, the entire output lens 3 can be lit, and there is no need to add additional cost and structural design for the high beam accompanying lighting effect in the low beam mode (the high beam accompanying lighting effect means that in the low beam mode, the lens corresponding to the high beam module 2 can also be lit), and a better appearance of the vehicle headlight lighting can also be obtained.

[0034] Multiple groups of the high beam module 2 are arranged in the left-right direction.

[0035] Multiple groups of the low beam module 1 are also arranged in the left-right direction.

[0036] In the vertical direction, a low beam bending component 5 and a high beam bending component 7 are arranged between the low beam light source 4 and the high beam light source 6. The light rays emitted by the low beam light source 4 and the high beam light source 6 first respectively shoot towards the low beam bending component 5 and the high beam bending component 7, and are reflected by the low beam bending component 5 and the high beam bending component 7 respectively and then enter the same incident surface of the output lens 3.

[0037] During the process of the vehicle headlight module disclosed in this application emitting light rays from the low beam module 1 and the high beam module 2, the low beam bending component 5 and the high beam bending component 7 can deflect the transmission optical paths of the low beam light rays and the high beam light rays. Specifically, for the original low beam module 1 and high beam module 2, part of the optical paths in the front-back direction are deflected by the low beam bending component 5 and the high beam bending component 7 and converted to other directions, shortening the transmission optical paths of the low beam light rays and the high beam light rays in the front-back direction while realizing the low beam light output and the high beam light output. The low beam bending component 5 and the high beam bending component 7 effectively reduce the front-back size of the vehicle headlight module and realize the flattening of the vehicle headlight module.

[0038] Embodiment 1:

[0039] Referring to Figure 1 and Figure 2 , the low - beam bending component 5 and the high - beam bending component 7 are arranged in the up - and - down direction.

[0040] Referring to Figure 1 and Figure 2 , the low - beam bending component 5 and the high - beam bending component 7 can be separately arranged or integrally formed. The integrally formed low - beam bending component 5 and high - beam bending component 7 can reduce the arrangement gap between the low - beam module 1 and the high - beam module 2 in the up - and - down direction, thereby reducing the volume of the headlight module.

[0041] Referring to Figure 1 and Figure 4 , the low - beam bending component 5 includes a low - beam reflection structure 51 and a low - beam bending structure 52 arranged up and down. The low - beam reflection structure 51 is arranged adjacent to the low - beam light source 4 so that the light emitted by the low - beam light source 4 can be reflected by the low - beam reflection structure 51 and reflected towards the low - beam bending structure 52, and then reflected by the low - beam bending structure 52 and emitted towards the light - emitting lens 3. Exemplarily, as shown in Figure 1 and Figure 4 , in the up - and - down direction, the low - beam reflection structure 51 is located above the low - beam bending structure 52. A low - beam reflection surface 511 is formed on one side of the low - beam reflection structure 51 facing the low - beam light source 4, and a low - beam bending reflection surface 521 is formed on the low - beam bending structure 52. The low - beam bending reflection surface 521 can be a total - reflection surface. The light emitted by the low - beam light source 4 is reflected by the low - beam reflection surface 511 and then reflected by the low - beam bending reflection surface 521 and emitted towards the light - emitting lens 3. Of course, the low - beam reflection structure 51 can also be located below the low - beam bending structure 52 (not shown in the figure), which does not affect the light transmission. In this embodiment, the low - beam bending reflection surface 521 of the low - beam bending structure 52 can deflect the low - beam optical path, deflecting the original front - to - back optical path of the low - beam module 1 upwards. At the same time, the low - beam light source 4 and the low - beam reflection structure 51 are arranged above the low - beam bending structure 52, finally realizing the low - beam function. The combined setting of the low - beam reflection structure 51 and the low - beam bending structure 52 effectively shortens the front - to - back size of the headlight module and realizes the flattening of the headlight module.

[0042] Referring to Figure 1 and Figure 4 , the low - beam reflection surface 511 is a curved surface, and the reflection direction of the light is towards the low - beam bending structure 52.

[0043] Referring to Figure 1 and Figure 4 , the low - beam cut - off line structure of the low - beam module 1 is located at the boundary position of the low - beam reflection structure 51 close to the low - beam light source 4.

[0044] Referring toFigure 1 and Figure 4 The low beam bending structure 52 is a transparent member with a cross section approximately in the shape of a triangle. The low beam bending structure 52 includes a low beam bending light incident surface 522, a low beam bending reflection surface 521 and a low beam bending light emitting surface 523. The low beam bending light incident surface 522 is a side surface of the low beam bending structure 52 facing the low beam reflection structure 51. The low beam bending light emitting surface 523 is a side surface of the low beam bending structure 52 facing the light emitting lens 3. The low beam bending reflection surface 521 is a side surface connecting the low beam bending light incident surface 522 and the low beam bending light emitting surface 523. The light emitted by the low beam light source 4 is collimated by the low beam reflection surface 511 and then emitted toward the low beam bending light incident surface 522 and enters the low beam bending structure 52. After being reflected by the low beam bending reflection surface 521, it is emitted from the low beam bending light emitting surface 523 and emitted toward the light emitting lens 3.

[0045] Reference Figure 1 and Figure 4 The angle between the section line of the longitudinal section of the low beam bending reflection surface 521 and the optical axis of the light output lens 3 is in the range of 45°±15°. The projection position of the low beam light type can be adjusted by controlling the angle. When the angle is less than 45°, the projection position of the low beam light type moves downward; when the angle is greater than 45°, the projection position of the low beam light type moves upward.

[0046] Reference Figure 1 and Figure 4 The low beam bending light incident surface 522 and / or the low beam bending reflection surface 521 and / or the low beam bending light emitting surface 523 may be a plane or a curved surface, or may be set as a focusing surface.

[0047] For example, the low beam bending reflective surface 521 is a focusing surface, which preferably focuses the light in the horizontal direction. The focal position is set at the low beam light source 4 or within 10 mm near it, or is set on the low beam reflective structure 51 or within 10 mm near it, which can better control the convergence and diffusion of the low beam light.

[0048] For example, the low beam bending incident light surface 522 is a focusing surface, and the focus is set at the low beam light source 4 or within a 10 mm range therefrom, or at the low beam reflection structure 51 or within a 10 mm range therefrom.

[0049] For example, the low beam bending light emitting surface 523 is a focusing surface, and its focus is set at the low beam light source virtual image 4 ′ or within 10 mm of the vicinity thereof, or at the low beam reflection structure virtual image 51 ′ or within 10 mm of the vicinity thereof.

[0050] It should be noted that, refer to Figure 4, the position of the virtual image of the low beam part is determined by the low beam bending reflection surface 521 of the low beam bending structure 52. The low beam light source 4 and the virtual image 4' of the low beam light source are symmetric about the low beam bending reflection surface 521, and the low beam reflection structure 51 and the virtual image 51' of the low beam reflection structure are also symmetric about the low beam bending reflection surface 521.

[0051] Referring to Figure 1 and Figure 4 , the high beam bending assembly 7 includes a high beam reflection structure 71 and a high beam bending structure 72 arranged up and down. The high beam reflection structure 71 is arranged adjacent to the high beam light source 6 so that the light emitted by the high beam light source 6 can be reflected by the high beam reflection structure 71 and reflected towards the high beam bending structure 72, and then reflected by the high beam bending structure 72 and emitted towards the light output lens 3. Exemplarily, as Figure 1 and Figure 4 shown, in the up and down direction, the high beam reflection structure 71 is located below the high beam bending structure 72. A high beam reflection surface 711 is formed on the side surface of the high beam reflection structure 71 facing the high beam light source 6. The high beam bending structure 72 is formed with a high beam bending reflection surface 721. The high beam bending reflection surface 721 can be a total reflection surface. The light emitted by the high beam light source 6 is reflected by the high beam reflection surface 711 and then emitted towards the high beam bending structure 72, and then reflected by the high beam bending reflection surface 721 and emitted towards the light output lens 3. Of course, the high beam reflection structure 71 can also be located above the high beam bending structure 72 (not shown in the figure), which does not affect the light transmission. In this embodiment, the high beam bending reflection surface 721 of the high beam bending structure 72 can realize the deflection of the high beam optical path, deflect the optical path of the high beam module 2 in the original front and back direction to the lower part, and at the same time, the high beam light source 6 and the high beam reflection structure 71 are arranged below the high beam bending structure 72, finally realizing the high beam function. The combined setting of the high beam reflection structure 71 and the high beam bending structure 72 effectively shortens the front and back dimensions of the headlight module and realizes the flattening of the headlight module.

[0052] Referring to Figure 1 and Figure 4 , the high beam reflection surface 711 is a curved surface, and the reflection direction of the light is towards the high beam bending structure 72.

[0053] Referring to Figure 1 and Figure 4The high beam bending structure 72 is a transparent member with a cross section approximately in the shape of a triangle. The high beam bending structure 72 includes a high beam bending light incident surface 722, a high beam bending reflection surface 721 and a high beam bending light emitting surface 723. The high beam bending light incident surface 722 is a side surface of the high beam bending structure 72 facing the high beam reflection structure 71. The high beam bending light emitting surface 723 is a side surface of the high beam bending structure 72 facing the light emitting lens 3. The high beam bending reflection surface 721 is a side surface connecting the high beam bending light incident surface 722 and the high beam bending light emitting surface 723. The light emitted by the high beam light source 6 is collimated by the high beam reflection surface 711 and then emitted toward the high beam bending light incident surface 722 and enters the high beam bending structure 72. After being reflected by the high beam bending reflection surface 721, it is emitted from the high beam bending light emitting surface 723 and emitted toward the light emitting lens 3.

[0054] Reference Figure 1 and Figure 4 The angle between the section line of the longitudinal section of the high beam bending reflection surface 721 and the optical axis of the light output lens 3 is in the range of 45°±15°. The projection position of the high beam light pattern can be adjusted by controlling the angle. When the angle is less than 45°, the projection position of the high beam light pattern moves downward; when the angle is greater than 45°, the projection position of the high beam light pattern moves upward.

[0055] Reference Figure 1 and Figure 4 The high beam bending light incident surface 722 and / or the high beam bending reflection surface 721 and / or the high beam bending light emitting surface 723 may be a plane or a curved surface, or may be set as a focusing surface.

[0056] For example, the high beam bending reflection surface 721 is a focusing surface, which preferably focuses the light in the horizontal direction. The focal position is set at the high beam light source 6 or within 10 mm near it, or is set on the high beam reflection structure 71 or within 10 mm near it, which can better control the convergence and diffusion of the high beam light.

[0057] For example, the high-beam bending light-entering surface 722 is a focusing surface, and the focus is set at the high-beam light source 6 or within a 10 mm range therefrom, or at the high-beam reflecting structure 71 or within a 10 mm range therefrom.

[0058] For example, the high beam bending light-emitting surface 723 is a focusing surface, and its focus is set at the low beam light source virtual image 6 ′ or within 10 mm of the vicinity thereof, or at the high beam reflecting structure virtual image 71 ′ or within 10 mm of the vicinity thereof.

[0059] It should be noted that, refer to Figure 4, the position of the virtual image of the high beam part is determined by the high beam bending reflection surface 721 of the high beam bending structure 72. The high beam light source 6 and the virtual image 6' of the low beam light source are symmetric about the high beam bending reflection surface 721. The high beam reflection structure 71 and the virtual image 71' of the high beam reflection structure are also symmetric about the high beam bending reflection surface 721.

[0060] Referring to Figure 1 and Figure 4 , the light-emitting lens 3 is an integral part. The focal point of the light-emitting lens 3 is located at the virtual image 4' of the low beam light source or within 10 mm in its vicinity, and / or at the virtual image 6' of the low beam light source or within 10 mm in its vicinity. The positions of the virtual image 4' of the low beam light source and the virtual image 6' of the low beam light source coincide or are close.

[0061] Referring to Figure 1 and Figure 3 , the headlight module disclosed in this embodiment further includes a circuit board 8. The circuit board 8 is arranged between the light-emitting lens 3 and the low beam module 1 and the high beam module 2. One side of the circuit board 8 is provided with the low beam module 1 and the high beam module 2, and the other side is provided with a heat dissipation structure 81. Specifically, the circuit board 8 is located on the side of the low beam module 1 and the high beam module 2 facing the light-emitting lens 3. To prevent the light rays emitted towards the light-emitting lens 3 from being blocked by the circuit board 8, the middle area of the circuit board 8 is set as an opening, so that the light rays emitted by the low beam module 1 and the high beam module 2 are suitable for passing through the opening and shooting towards the light-emitting lens 3. In addition, to meet the purpose of arranging the high beam light source 6 and the low beam light source 4 on the same circuit board 8, while setting the middle area of the circuit board 8 as an opening, at least one side of the left and right sides of the circuit board 8 remains connected. For example, as Figure 3 shown, the circuit board 8 has an overall C-shaped structure. The low beam light source 4 and the high beam light source 6 are both arranged on the same side of the same circuit board 8. The low beam light source 4 and the high beam light source 6 share the same circuit board 8, which reduces the cost; and the low beam light source 4 and the high beam light source 6 are arranged at intervals up and down on the circuit board 8, so that there is enough space to arrange the heat dissipation structure 81 on the other side of the circuit board 8, improving the heat dissipation effect; the circuit board 8 and the heat dissipation structure 81 are arranged between the light-emitting lens 3 and the low beam module 1 and the high beam module 2 on the premise of not blocking the low beam light and the high beam light, reducing the size of the headlight module in the front-rear direction, and being more conducive to the flattening of the headlight module. Further, the heat dissipation structure 81 is a radiator, and the low beam module 1 and the high beam module 2 use the same radiator for heat dissipation, reducing the number of parts, lowering the cost, and saving space.

[0062] Through the above technical solutions, for the low beam module 1 of the present application, the original front and rear part of the light path is deflected to the up and down direction through the setting of the low beam bending structure 52, and finally the low beam light output is realized through the setting of the low beam reflection structure 51. The combined setting of the low beam reflection structure 51 and the low beam bending structure 52 effectively shortens the size of the headlight module in the front-rear direction and realizes the flattening of the headlight module;

[0063] For the original optical paths of the front and rear parts of the high beam module 2, through the setting of the high beam bending structure 72, part of the optical paths are deflected to the up and down directions, and finally, through the setting of the high beam reflection structure 71, high beam light output is realized. The combined setting of the high beam reflection structure 71 and the high beam bending structure 72 effectively shortens the size of the headlight module in the front and rear directions, achieving the flattening of the headlight module;

[0064] Meanwhile, the vertically arranged high beam module 2 and low beam module 1 share one light incident surface of the light output lens 3. There is no need to distinguish between the high beam and low beam light incident surfaces of the light output lens 3, and the effect of accompanying lighting can be achieved, with a good lighting appearance;

[0065] In addition, the low beam light source 4 and the high beam light source 6 are arranged on the same side of the same circuit board 8, reducing the setting cost of the circuit board 8 and facilitating the arrangement of the heat dissipation structure 81, improving the heat dissipation efficiency; and the circuit board 8 and the heat dissipation structure 81 are arranged between the light output lens 3 and the low beam module 1 and the high beam module 2, further reducing the size of the headlight module in the front and rear directions, achieving the flattening of the headlight module.

[0066] On the other hand, the present application also discloses a headlight including the above-mentioned headlight module.

[0067] Embodiment 2:

[0068] Referring to Figure 5 and Figure 6 , a headlight module is disclosed in this embodiment. Based on Embodiment 1, the difference from Embodiment 1 is that the low beam reflection structure 51 and the low beam bending structure 52 are an integral part. The low beam reflection surface 511 is connected to the low beam bending light incident surface 522. The surface of the low beam reflection surface 511 can be aluminized. The light emitted by the low beam light source 4 is directly projected onto the low beam bending reflection surface 521 by the low beam reflection surface 511, and after being reflected by the low beam bending reflection surface 521, it is emitted from the low beam bending light output surface 523 and transmitted to the light incident surface of the light output lens 3. The setting method of the low beam reflection structure 51 and the low beam bending structure 52 being an integral part reduces the distance between the low beam reflection structure 51 and the low beam bending structure 52, making the headlight module more compact up and down, smaller in volume, and at the same time reducing the number of components and being more convenient for assembly.

[0069] The high-beam reflection structure 71 and the high-beam bending structure 72 are an integral part. The high-beam reflection surface 711 is connected to the high-beam bending incident light surface 722. The surface of the high-beam reflection surface 711 can be aluminized. The light emitted by the high-beam light source 6 is directly emitted from the high-beam reflection surface 711 to the high-beam bending reflection surface 721, and after being reflected by the high-beam bending reflection surface 721, it is emitted from the high-beam bending light-emitting surface 723 and transmitted to the incident light surface of the light-emitting lens 3. The arrangement that the high-beam reflection structure 71 and the high-beam bending structure 72 are an integral part reduces the distance between the high-beam reflection structure 71 and the high-beam bending structure 72, making the headlight module more compact up and down, smaller in volume, while reducing the number of components and making the assembly more convenient.
