Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting, in particular to a headlamp module and a vehicle. Background Art

[0002] Existing projection modules for automobile low beam lights generally include a light source and a reflector and an optical lens arranged in sequence along the light transmission direction. A cutoff line structure is provided at the boundary of the reflector. The light source illuminates the reflector, and the light reflected by the reflector is then irradiated onto the road surface through the optical lens, forming a low beam light shape with a light and dark cutoff line.

[0003] If you want to achieve high beam, you need a separate projection module for the high beam of the car, which causes the car lighting system to occupy a large space, which is not conducive to the flat design of the car lights. If you want to achieve the integration of high and low beam, on the basis of the above-mentioned projection module for the low beam of the car, you need to place the projection module for the low beam in the high beam light path, which causes the projection module for the low beam to block the high beam light. In addition, the light emitted by the light source is reflected by the reflector and emitted to the optical lens in the form of divergent light. Some of the light may not be able to enter the optical lens, resulting in light loss and reduced light efficiency. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0037] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. It should be further explained that, if the light converges to the focus, it does not mean that it converges to the focus in the strict sense, but it can also converge near the focus (<2mm). Similarly, the focus is set at the cutoff line structure 31, which includes both the focus being set on the cutoff line structure 31 and the focus being set near the cutoff line structure 31.

[0039] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Please refer to Figures 1 to 7The embodiment of the present application provides a headlamp module 100, including a low-beam optical component 10, a high-beam optical component 20, a reflective element 30 and a light-emitting element 40; the low-beam optical component 10 includes a low-beam light source 12 and a low-beam focusing element 11, and the low-beam light source 12 is located at the first focus of the low-beam focusing element 11; the high-beam optical component 20 includes a high-beam light source 22 and a high-beam focusing element 21, and the high-beam light source 22 is located at the first focus of the high-beam focusing element 21; the reflective element 30 includes a reflective surface, and a cutoff line structure 31 for forming a bright and dark cutoff line is provided at the end edge of the reflective surface close to the low-beam focusing element 11, and the reflective surface is an ellipsoidal surface A reflecting surface or an ellipsoidal reflecting surface; the second focus of the low beam focusing element 11 coincides with the first focus of the reflecting surface, and the outgoing light of the low beam optical component 10 is scattered into the reflecting surface after being converged to the first focus of the reflecting surface, and is emitted to the light emitting element 40 after being reflected by the reflecting surface, and is refracted by the light emitting element 40 to form a low beam light shape; the second focus of the high beam focusing element 21 coincides with the focus of the light emitting element 40, and is located at the cut-off line structure 31, and the outgoing light of the high beam optical component 20 is scattered into the light emitting element 40 after being converged to the focus of the light emitting element 40, and is refracted by the light emitting element 40 to form a high beam light shape. The headlamp module 100 can realize the integration of high and low beams without interfering with each other, and the outgoing light of the low beam optical component 10 is reflected by the reflective surface and then emitted to the light emitting element 40 in the form of parallel light, ensuring that more light can enter the light emitting element 40, reducing the loss of light and improving the light effect of the low beam.

[0041] like Figures 1 to 3As shown, the headlamp module 100 includes a low beam optical component 10, a high beam optical component 20, a reflective element 30 and a light emitting element 40. The low beam optical component 10 includes a low beam light source 12 and a low beam focusing element 11, and the low beam light source 12 is located at the first focus of the low beam focusing element 11. The high beam optical component 20 includes a high beam light source 22 and a high beam focusing element 21, and the high beam light source 22 is located at the first focus of the high beam focusing element 21. The reflective element 30 includes a reflective surface, and a cutoff line structure 31 for forming a bright and dark cutoff line is provided at the end edge of the reflective surface close to the low beam focusing element 11, and the reflective surface is an ellipsoidal reflective surface or a quasi-ellipsoidal reflective surface. In the actual assembly process, regarding the installation position of the reflective element 30, those skilled in the art should be able to make reasonable selections and designs according to the spatial shape of the headlamp module 100 or the actual size of the headlamp module 100. No specific restrictions are made here. It is only necessary to make the low beam optical component 10, the high beam optical component 20, the reflective element 30 and the light emitting element 40 reasonably arranged in the space of the headlamp module 100, and the reflective element 30 is located on the light emitting path of the low beam optical component 10, the second focus of the low beam focusing element 11 coincides with the first focus of the reflecting surface, the second focus of the high beam focusing element 21 coincides with the focus of the light emitting element 40, and is located at the cut-off line structure 31. The transmission path of the low beam light and the transmission path of the high beam light are independent of each other and do not affect each other, that is, the high and low beam light paths do not interfere with each other. At the same time, the spatial layout of the headlamp module 100 can also be made more flexible.

[0042] As described above, the headlamp module 100 provided by the present application is located on the light emitting path of the low beam optical component 10 through the reflective element 30, the second focus of the low beam focusing element 11 coincides with the first focus of the reflective surface, a cutoff line structure 31 for forming a bright and dark cutoff line is provided at the edge of the end of the reflective surface, and the second focus of the high beam focusing element 21 coincides with the focus of the light emitting element 40 and is located at the cutoff line structure 31, that is, through the cooperation of the low beam optical component 10, the high beam optical component 20 and the reflective surface, the outgoing light of the low beam optical component 10 can be scattered into the reflective surface after being converged to the first focus of the reflective surface, and after being reflected by the reflective surface, it is emitted to the light emitting element 40, and after being refracted by the light emitting element 40, it forms a low beam light shape with a bright and dark cutoff line. At the same time, the outgoing light of the high beam optical component 20 can be scattered into the light emitting element 40 after being converged to the focus of the light emitting element 40, and after being refracted by the light emitting element 40, it forms a high beam light shape.

[0043] Compared with the automobile lamps in the prior art, the headlamp module 100 provided by the present application can not only realize the integration of high and low beams without interfering with each other, that is, it can make the low beam optical path of the low beam optical component 10 and the high beam optical path of the high beam optical component 20 not affect each other, and because the reflective element 30 includes a reflective surface, and the reflective surface is an ellipsoidal reflective surface or a quasi-ellipsoidal reflective surface, the outgoing light of the low beam optical component 10 is reflected by the reflective surface and emitted to the light emitting element 40 in the form of parallel light, ensuring that more light can enter the light emitting element 40, reducing the loss of light and improving the light effect of the low beam. In addition, in the prior art, some automobile lamps realize the switching between high and low beams through a driving mechanism and a visor connected to the driving mechanism, which has the problems of inconvenient switching, switching failure, and high noise. The headlamp module 100 provided by the present application, in the process of switching the light shape of high beam and low beam, does not require the participation of the driving mechanism, so it also has the advantages of convenient switching, stable and reliable, and no noise.

[0044] In some embodiments, Figure 1 and Figure 3 As shown, the low beam light source 12 is fixed in the space of the headlamp module 100 through the first bracket 13. Figure 4 and Figure 5 As shown, when the low-beam light source 12 located at the first focus of the low-beam focusing element 11 is turned on, the light emitted by the low-beam light source 12 is scattered into the low-beam focusing element 11 and is reflected by the low-beam focusing element 11 and is focused to the second focus of the low-beam focusing element 11. Since the second focus of the low-beam focusing element 11 coincides with the first focus of the reflective surface, it is equivalent to the low-beam light source 12 being imaged at the first focus of the reflective surface. Therefore, the focused light will be scattered into the reflective surface and reflected by the reflective surface and then incident on the incident surface of the light emitting element 40 in the form of parallel light, and finally refracted by the light emitting surface of the light emitting element 40 to form a low-beam light shape.

[0045] Compared with other embodiments, in this embodiment, the reflective surface is in the form of an ellipsoidal reflective surface or a quasi-ellipsoidal reflective surface, and the light can be incident on the light emitting element 40 to the greatest extent to form a low-beam light shape, so the light loss is less and the light efficiency is higher. From another perspective, when the amount of light incident on the light emitting element 40 is the same, the upper and lower openings of the light emitting element 40 of this technical solution are smaller than those of the prior art.

[0046] In some embodiments, Figure 1 and Figure 3 As shown, the high beam light source 22 is fixed in the space of the front lighting module by the second bracket 23. Figure 6 and Figure 7As shown, when the high-beam light source 22 located at the first focus of the high-beam focusing element 21 is turned on, the light emitted by the high-beam light source 22 is scattered into the high-beam focusing element 21 and is reflected by the high-beam focusing element 21 and then converged to the second focus of the high-beam focusing element 21. A portion of the light is directly emitted to the light incident surface of the light emitting element 40 to form a first illumination light shape, and another portion of the light is emitted to the high-beam focusing element 21 to form a first illumination light shape. Figure 1 The high-beam reflecting surface 32 shown is emitted toward the light emitting element 40 after being reflected by the high-beam reflecting surface 32 to form a second illumination light shape. The first illumination light shape and the second illumination light shape are superimposed to form the high-beam light shape.

[0047] In some embodiments, the second focus of the reflective surface is located on the optical path of the outgoing light of the low beam optical assembly 10 after being reflected by the reflective surface and emitted to the light emitting element 40. Preferably, the second focus of the reflective surface is set at the light incident surface of the light emitting element 40 to minimize the light incident surface. In some embodiments, the angle between the line connecting the first focus and the second focus of the reflective surface and the optical axis of the light emitting element 40 ranges from -30° to 30°.

[0048] As is known to all, the ellipsoidal reflector has such an optical property that the light emitted from any focus, or the light passing through the focus, can be converged to another focus area after passing through the ellipsoidal reflector. Figure 4 and Figure 5 As shown, the outgoing light of the low beam optical component 10 is scattered into the reflective surface after being converged to the first focus of the reflective surface, and is reflected by the ellipsoidal reflector and emitted to the second focus area of ​​the reflective surface. Since the second focus of the reflective surface is located on the optical path of the outgoing light of the low beam optical component 10 and emitted to the light emitting element 40 after being reflected by the reflective surface, it can ensure that the light enters the light emitting element 40 and forms a low beam light shape with a bright and dark cut-off line after being refracted by the light emitting element 40. The quasi-ellipsoidal shape is a shape that approximates an ellipsoidal surface, and is formed by making certain adaptive adjustments based on the shape of the ellipsoidal surface for light shape optimization.

[0049] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the low beam optical assembly 10 formed by the low beam light source 12 and the low beam focusing element 11 can be arranged below the light emitting element 40 and the high beam optical assembly 20 formed by the high beam light source 22 and the high beam focusing element 21, and the cut-off line structure 31 can be arranged at the end edge of the lower end of the reflective surface. It should be noted that the "below" and "lower end" mentioned here are relative to the use position of the headlamp module 100. In this way, as Figure 6 As shown, the low beam optical assembly 10 can be arranged away from the light emitting path of the high beam optical assembly 20 so as not to interfere with the high beam light.

[0050] In some embodiments, Figure 5 and Figure 7 As shown, the low beam focusing element 11 is an ellipsoidal reflector or a quasi-ellipsoidal reflector, and / or the high beam focusing element 21 is an ellipsoidal reflector or a quasi-ellipsoidal reflector.

[0051] As is known to all, the ellipsoidal reflector has such an optical property that the light emitted from any focus, or the light passing through the focus, can be converged to another focus area after passing through the ellipsoidal reflector. Figure 4 and Figure 5 As shown, the light emitted by the low beam light source 12 (located at the first focus of the ellipsoidal reflector) can be converged to the first focus area of ​​the reflecting surface (i.e., the second focus area of ​​the ellipsoidal reflector) after passing through the ellipsoidal reflector. Similarly, Figure 6 and Figure 7 As shown, the light emitted by the high beam light source 22 (located at the first focus of the ellipsoidal reflector) can be converged to the focus area of ​​the light emitting element 40 (i.e., the second focus area of ​​the ellipsoidal reflector) after passing through the ellipsoidal reflector. The quasi-ellipsoidal shape is a shape that approximates an ellipsoidal surface, and is formed by making certain adaptive adjustments based on the shape of the ellipsoidal surface for light shape optimization.

[0052] As an practicable manner, the low beam focusing element 11 is a concentrator, and / or the high beam focusing element 21 is a concentrator. As an practicable manner, the reflective element 30 is a reflective plate to reflect the incident light through the reflective plate, and the light emitting element 40 is a lens to redistribute the energy of the incident light through the lens before emitting it.

[0053] When the low beam focusing element 11 is a concentrator, the low beam light source 12 is located at the focus of the incident end of the corresponding concentrator. In this way, the light emitted by the low beam light source 12 can be converged by the corresponding concentrator and emitted from the focal area of ​​the output end of the corresponding concentrator; similarly, when the high beam focusing element 21 is a concentrator, the high beam light source 22 is located at the focus of the incident end of the corresponding concentrator. In this way, the light emitted by the high beam light source 22 can be converged by the corresponding concentrator and emitted from the focal area of ​​the output end of the corresponding concentrator.

[0054] In some embodiments, Figure 5 and Figure 7As shown, the number of low beam light sources 12 and low beam focusing elements 11 are both multiple, the multiple low beam light sources 12 are arranged in sequence, and the multiple low beam focusing elements 11 are arranged in one-to-one correspondence with the multiple low beam light sources 12; the number of high beam light sources 22 and high beam focusing elements 21 are both multiple, the multiple high beam light sources 22 are arranged in sequence, and the multiple high beam focusing elements 21 are arranged in one-to-one correspondence with the multiple high beam light sources 22. The number of reflective surfaces is multiple, and the multiple reflective surfaces are arranged in one-to-one correspondence with the multiple low beam focusing elements 11, and a cut-off line structure 31 for forming a bright and dark cut-off line is provided at the end edge of each reflective surface close to the low beam focusing element 11. In some embodiments, the number of high beam focusing elements 21 may be less than or equal to the number of low beam focusing elements 11.

[0055] It should be noted that, in this document, when the term “a plurality of A’s and a plurality of B’s are arranged in one-to-one correspondence” is used, it should be understood that each A is arranged in correspondence with one and only one B. For example, it should be understood that each low-beam focusing element 11 is arranged in correspondence with one and only one low-beam light source 12.

[0056] According to this embodiment, by providing a plurality of sequentially arranged low-beam light sources 12 and a plurality of low-beam focusing elements 11 corresponding to each of them and a plurality of reflective surfaces, the low-beam light shape finally formed can be made more uniform. Similarly, by providing a plurality of sequentially arranged high-beam light sources 22 and a plurality of high-beam focusing elements 21 corresponding to each of them, the high-beam light shape finally formed can also be made brighter.

[0057] In some embodiments, the light emitting element 40 may be a bidirectional collimated light emitting element, which may include a light input portion with horizontal unidirectional collimation and a light output portion with vertical unidirectional collimation. The light input portion of the light emitting element 40 may include multiple light input surfaces arranged in one-to-one correspondence with the reflective surfaces.

[0058] In some embodiments, the light incident surface of the light emitting element 40 may be a curved surface stretched up and down to collimate the light left and right, and the light emitting portion of the light emitting element 40 may include a curved surface stretched left and right to collimate the light up and down. It should be noted that the "up and down" and "left and right" mentioned here are relative to the use position of the headlamp module 100. By adopting a bidirectional collimating light emitting element, the light incident portion and the light emitting portion of the light emitting element 40 both have a single-direction dimming function, and the surface shapes of the two optical surfaces can be adjusted independently, which greatly simplifies the dimming steps in the light distribution process. In addition, when the lighting module of this embodiment is applied to a vehicle, a narrow opening light emitting element 40 can be realized, and a vehicle with a narrow and long headlamp shape can be obtained, which meets market demand.

[0059] It is worth noting that the high beam light source 22 of the above-mentioned high beam optical assembly 20 can be replaced with a signal light source, so that the headlamp module 100 provided in the present application can realize the integration of the low beam optical assembly 10 and the signal light optical assembly.

[0060] The embodiment of the present application further provides a vehicle, comprising the above-mentioned headlamp module 100. Since the structure and beneficial effects of the headlamp module 100 have been described in detail in the above-mentioned embodiment, they will not be described again here.
