Description

Technical Field

[0001] This application relates to the technical field of vehicle lighting, and particularly to an optical module and a vehicle. Background Art

[0002] Currently, the main market requirements for headlight modules are compact size and high efficiency, and they need to adapt to the styling requirements of various vehicle lamps while ensuring good optical performance. The mainstream design on the market at present is to design the low beam and all-weather lights as independent modules respectively. This design has relatively high requirements for the internal space of the lamp, and it will increase the cost of the lamp.

[0003] Moreover, with the continuous improvement of the market's requirements for vehicle lights, the internal design space of the lamp is continuously compressed, and the difficulty of the space design using traditional independent control modules is increasing; and the traditional independent control modules divide different functions into multiple modules, with many assembly steps in the production process, increasing the probability of defective products, resulting in problems with the functions of vehicle lights; at the same time, the control modules are expensive, and using independent control modules also requires separate independent heat dissipation devices, which is not conducive to cost control. Summary of the Invention

[0004] In order to solve the above problems, the technical solutions adopted in the embodiments of this application are as follows:

[0005] This application discloses an optical module, including:

[0006] A collimation module, configured to collimate at least two types of functional light rays and emit light along the light-emitting direction of the collimation module;

[0007] An inner lens module, located in the light-emitting direction of the collimation module, and the light-incident side of the inner lens module faces the collimation module;

[0008] An outer lens module, arranged on the light-emitting side of the inner lens module.

[0009] In some embodiments, the collimation module includes: a low beam mirror and an all-weather light mirror arranged in sequence in a direction perpendicular to the light-emitting direction, respectively configured to collimate the light rays emitted by the light sources at their respective focal points.

[0010] In some embodiments, the low beam mirror and the all-weather light mirror are arranged side by side;

[0011] It further includes a heat sink, the heat sink has a mounting surface, and the light source, the low beam mirror, and the all-weather light mirror are fixed to the mounting surface.

[0012] In some embodiments, the collimation module includes two or more reflectors, and the inner lens module includes two or more collimation adjustment units. Each collimation adjustment unit is correspondingly arranged in the light-emitting direction of each reflector for collimating the light emitted by the reflector.

[0013] In some embodiments, the collimation direction of the collimation adjustment unit is the first direction, and the collimation direction of the outer lens module is the second direction that intersects the first direction.

[0014] In some embodiments, the inner lens module includes:

[0015] Inner lens I, which is in the light-emitting direction of the low beam reflector;

[0016] Inner lens II, which is arranged side by side with Inner lens I and is in the light-emitting direction of the all-weather lamp reflector.

[0017] In some embodiments, Inner lens I and Inner lens II are integrally formed.

[0018] In some embodiments, the collimation module includes a follow-up steering reflector, and a light source is disposed at or near the focus of the follow-up steering reflector for collimating the light emitted by the light source and emitting follow-up steering light in the light-emitting direction.

[0019] In some embodiments, the height of the outer lens module in the up-down direction is 10 - 25 mm, and the width in the left-right direction is 120 - 250 mm.

[0020] A vehicle includes the above-mentioned optical module.

[0021] This application can integrate two functional modules and share one outer lens, reducing the number of components and the layout space of the components. Moreover, it can save the space in the direction perpendicular to the adjacent direction. Generally, the space occupied by the optical module is significantly reduced, which is beneficial to the flat and miniaturized design of the space. The height in the up-down direction can be reduced to 10 mm, saving the overall material cost of the lamp;

[0022] Due to the high integration degree of the module, there are few independent modules and few assembly steps, reducing the probability of defective products and effectively guaranteeing the normal realization of the vehicle lamp function. At the same time, the integrated module has a low price and only requires one corresponding heat dissipation device, which is beneficial to controlling the overall cost.

[0038] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] Reference Figure 1 - Figure 2 , the present application provides an optical module, comprising:

[0040] A collimation module 10, configured to collimate at least two types of functional light rays and emit light along the light-emitting direction of the collimation module 10;

[0041] An inner lens module 30, which is in the light-emitting direction of the collimation module 10, and the light-incident side of the inner lens module 30 faces the collimation module 10;

[0042] An outer lens module 20, which is arranged on the light-emitting side of the inner lens module 30.

[0043] Specifically, the collimation module 10 collimates light rays and emits light along its light-emitting direction, and the light rays enter the inner lens module 30, and the inner lens module 30 collimates / converges and adjusts the light rays;

[0044] After the inner lens module 30 collimates / converges and adjusts the light rays, the light rays enter the outer lens in front of the light-emitting direction, and the outer lens module 20 adjusts each light ray and emits it outward.

[0045] In the present application, the various functional lights collimated by the collimating module 10 are respectively adjusted and emitted from a unified outer lens module 20 to form light patterns of different functional types, thereby integrating at least two functions into one, sharing one outer lens. The light emission of the collimating module 10 can be controlled by an electronic circuit.

[0046] The present application integrates multiple functional modules in adjacent directions and shares one outer lens, which reduces the number of components and the layout space of the components, and can save space in the direction perpendicular to the adjacent directions. Overall, the space occupied by the optical module is significantly reduced, which is conducive to the flattening and miniaturization of the space, saving the overall material cost of the lamp. The height of the outer lens module 20 in the vertical direction can be reduced to 10mm, and the horizontal width in the left and right direction is 120-250mm; the orientation display is as follows Figure 1 and Figure 2 shown.

[0047] Due to the high module integration, fewer independent modules and fewer assembly steps, the probability of defective products is reduced, and the normal function of the headlights is effectively guaranteed;

[0048] At the same time, the integrated module has a low price and only requires a corresponding heat dissipation device, which is conducive to controlling the overall cost.

[0049] refer to Figure 2 In this embodiment, the collimating module 10 includes: a low beam reflector 11 and an all-weather light reflector 12 which are sequentially arranged in a direction perpendicular to the light emitting direction, and are respectively used to collimate the light emitted by the light sources at their respective focal points.

[0050] Specifically, when the collimating module 10 includes seven side-by-side low-beam reflectors 11 and two side-by-side all-weather light reflectors 12, a light source is correspondingly arranged at the focus or near the focus of each reflector. The seven low-beam reflectors 11 collimate the light emitted by the light source, and emit it from the outer lens after being adjusted by the inner lens module 30, thereby forming a low-beam light type; the two all-weather light reflectors 12 collimate the light emitted by the light source, and emit it from the outer lens after being adjusted by the inner lens module 30, thereby forming an all-weather light type.

[0051] This embodiment can emit low beam and all-weather light, thereby integrating the two functions into one, sharing one outer lens, and the light emission can be controlled by an electronic circuit; this embodiment saves parts and space, is conducive to the flattening and miniaturization design of the entire lamp space, and the number of heat dissipation devices in the lamp is reduced and the cost is lower.

[0052] refer to Figure 3 , in some embodiments, the low beam reflector 11 and the all-weather light reflector 12 are arranged side by side and continuously and are integrally formed;

[0053] It further includes a heat dissipation body 40, and the heat dissipation body 40 has a mounting surface 41, and the light source, the low beam reflector 11, and the all-weather lamp reflector 12 are fixed to the mounting surface.

[0054] Specifically, the light source, the low beam reflector 11, and the all-weather lamp reflector 12 are integrally fixed to the mounting surface 41 of the heat dissipation body 40. By using one heat dissipation body 40, the heat dissipation of the reflectors with two functions can be achieved, which is beneficial to controlling the overall cost of the lamp. Moreover, in this embodiment, the low beam reflector 11 and the all-weather lamp reflector 12 are arranged side by side, saving space; the two parts are integrally formed, reducing the number of parts included in the vehicle lamp. The unified integrated assembly of the two parts can also avoid the cumulative error caused by separate assembly, and the assembly accuracy is relatively high.

[0055] Furthermore, the collimation module 10 includes two or more reflectors, and the inner lens module 30 includes two or more collimation adjustment units 3a. Each collimation adjustment unit 3a is correspondingly arranged in the light-emitting direction of each reflector for collimating the light emitted by the reflector.

[0056] Specifically, taking the collimation direction of the collimation adjustment unit 3a as the horizontal and / or vertical direction as an example. When the incident surface of the collimation adjustment unit 3a is set as a collimation surface (in the form of a cylinder or a quasi-cylinder, formed by the arc in the horizontal plane extending along the normal direction of the horizontal plane) extending along the vertical direction, its collimation direction is the horizontal direction. When the incident surface of the collimation adjustment unit 3a is set as a collimation surface (in the form of a cylinder or a quasi-cylinder, formed by the arc in the vertical plane extending along the normal direction of the vertical plane) extending along the horizontal direction, its collimation direction is the vertical direction. The light emitted by each reflector enters the outer lens for secondary collimation / focus adjustment after being collimated by the corresponding collimation adjustment unit 3a, and then a complete light pattern is emitted.

[0057] Reference Figure 3 , in some embodiments, the collimation direction of the collimation adjustment unit 3a is the first direction, and the collimation direction of the outer lens module 20 is the second direction intersecting the first direction.

[0058] Specifically, taking the first direction as the horizontal direction and the second direction as the vertical direction as an example, when the incident surface and / or the exit surface of the outer lens module 20 is set as a collimation surface (in the form of a cylinder or a quasi-cylinder, formed by the arc in the vertical plane extending along the normal direction of the vertical plane) extending along the horizontal direction, its collimation direction is the vertical direction. The light emitted by the reflector is first horizontally collimated by the collimation adjustment unit 3a and then vertically collimated by the outer lens module 20 to form the expected low beam or all-weather lamp light pattern.

[0059] Of course, in other embodiments, the first direction can adopt other directions in space, and the second direction only needs to intersect the first direction, which is not limited here.

[0060] Reference Figure 2 In this embodiment, the inner lens module 30 includes:

[0061] Inner lens I 31, which is in the light-emitting direction of the low-beam reflector 11; and,

[0062] Inner lens II 32, which is arranged side by side with the inner lens I 31 on the mounting plate 33, and the inner lens II 32 is in the light-emitting direction of the all-weather lamp reflector 12.

[0063] Specifically, the light emitted by the low-beam reflector 11 is adjusted by the inner lens I 31 and then emitted from the outer lens, forming a low-beam light pattern; the light emitted by the all-weather lamp reflector 12 is adjusted by the inner lens II 32 and then emitted from the outer lens, forming an all-weather lamp light pattern.

[0064] The inner lens I 31 and the inner lens II 32 are fixed on a mounting plate 33, reducing the number of components and the layout space of the components; the inner lens I 31 and the inner lens II 32 are integrally formed. The unified integrated assembly of the two parts can also avoid the cumulative error caused by separate assembly, and the assembly accuracy is relatively high.

[0065] Reference Figure 2 In some embodiments, the inner lens I 31 and the inner lens II 32 are integrally formed. In this embodiment, the inner lens I 31 and the inner lens II 32 are arranged side by side and can be integrally formed. The two parts are integrated into one, reducing the number of parts included in the vehicle lamp. The unified assembly of the two parts can avoid the cumulative error caused by separate assembly, and the assembly accuracy is relatively high.

[0066] Furthermore, the number of the low-beam reflectors 11 and the matching inner lens I 31 can be set to two or more groups. For example, Figure 2 Seven low-beam reflectors 11 and the corresponding inner lens I 31 are provided to form a better light pattern with better broadening. In actual use, only one or several of the low-beam reflectors 11 and the matching inner lens I 31 can be selected and lit according to the lighting requirements, and the usage method is flexible. The number of the all-weather lamp reflectors 12 and the matching inner lens II 32 can be set to two or more groups, and the light-emitting broadening area is relatively large.

[0067] Of course, in addition to the above embodiments, the collimating module 10 of the present application may further include reflectors or condensers with other light-emitting functions, such as fog lamps and corner lamps, etc., which are not limited herein.

[0068] Reference Figure 2 In some embodiments, grid patterns are arranged on the light-incident side surface of the outer lens module 20 for homogenizing the light distribution.

[0069] Specifically, square or diamond grid patterns are arranged on the light-incident side surface of the outer lens module 20 for homogenizing the light energy distribution.

[0070] The present application also provides a vehicle, including the optical module described in any one of the above.

[0071] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.

[0072] For those skilled in the art, it is obvious that the present application is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claimed rights.
