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 demands for headlight modules are compact size and high efficiency, and they need to adapt to the styling requirements of various vehicle lamps on the premise of ensuring good optical performance. Currently, the mainstream design on the market is to design the low beam, electronic follow - up steering, and all - weather lamp as three independent modules respectively. This design has relatively high requirements for the internal space of the lamp and will increase the cost of the lamp.

[0003] Moreover, with the continuous improvement of market requirements for vehicle lamps, the internal design space of the lamp is constantly compressed, and the difficulty of space design using traditional independent control modules is increasing; moreover, the traditional independent control module divides different functions into multiple modules, with more assembly steps in the production process, increasing the probability of defective products, resulting in problems with the functions of the vehicle lamp; at the same time, the control module is expensive, and using an independent control module also requires separate independent heat dissipation devices, which is not conducive to cost control.

[0015] In some embodiments, the second collimation module includes a follow-up steering mirror, and a light source is configured at or near the focus of the follow-up steering mirror for collimating the light emitted by the light source and emitting follow-up steering light in the light-emitting direction.

[0016] In some embodiments, the outer lens module includes:

[0017] The first outer lens, which is arranged on the light-emitting side of the inner lens module;

[0018] The second outer lens, which is arranged in front of the light-emitting direction of the second collimation module; the light-incident side surface of the second outer lens bulges towards the second collimation module to form a light-condensing part, and a grid pattern is arranged on the surface of the light-condensing part for homogenizing the light distribution;

[0019] Wherein, the light-emitting side surfaces of the first outer lens and the second outer lens are smoothly connected in a transitional manner.

[0020] In some embodiments, there is a first optical path transmission space between the first outer lens and the inner lens module, a second optical path transmission space between the second outer lens and the second collimation module, and a light blocking structure is arranged between the first optical path transmission space and the second optical path transmission space.

[0045] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0046] Refer to Figures 1 - 2 , the present application provides an optical module, including:

[0047] The first collimation module 10 is used to collimate light and emit light along the light-emitting direction of the first collimation module 10;

[0048] The second collimation module 20 is arranged on the side of the first collimation module 10 and is used to collimate light and emit light along the light-emitting direction of the second collimation module 20;

[0049] The inner lens module 30 is in the light-emitting direction of the first collimation module 10, and the light-incident side of the inner lens module 30 faces the first collimation module 10;

[0050] The outer lens module 40 is arranged on the light-emitting side of the inner lens module 30 and in front of the light-emitting direction of the second collimation module 20.

[0051] Specifically, the first collimation module 10 collimates light and emits light along its light-emitting direction, and the light enters the inner lens module 30, and the inner lens module 30 collimates / converges and adjusts the light; the second collimation module 20 can also collimate light and emit light along its light-emitting direction;

[0052] After the light collimated / converged and adjusted by the inner lens module 30 and the light collimated by the second collimation module 20 respectively enter the outer lens in front of the light-emitting direction, the outer lens adjusts each light and emits it outward.

[0053] In the present application, the light collimated by the first collimation module 10 and the second collimation module 20 are respectively adjusted in different ways and then emitted from a unified outer lens module 40, and different functional types of light patterns can be formed, so that at least two functions are integrated into one, sharing one outer lens. The light emission of each first collimation module 10 and second collimation module 20 can be controlled by an electronic circuit.

[0054] In this application, multiple functional modules are integrated in adjacent directions and share an external lens, reducing the number of components and the layout space of 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 conducive to the flat and miniaturized design of the space, saving the overall material cost of the lamp. The height of the external lens module 40 in the up and down direction can be reduced to 10 mm, and the lateral width in the left and right direction is 120 - 250 mm; the azimuth display is as Figure 1 and Figure 2 shown.

[0055] 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 defects, and strongly guaranteeing the normal realization of the vehicle lamp functions;

[0056] At the same time, the integrated module has a low price, and only one heat dissipation device needs to be correspondingly set, which is beneficial to controlling the overall cost.

[0057] Referring to Figure 2 , in this embodiment, the first collimation module 10 includes: a low beam mirror 11 and an all-weather lamp mirror 12.

[0058] Specifically, when the first collimation module 10 includes a plurality of low beam mirrors 11 and a plurality of all-weather lamp mirrors 12, a light source is arranged at or near the focus of the mirrors. The low beam mirror 11 and the all-weather lamp mirror 12 collimate the light emitted by the light source, and after being adjusted by the inner lens module 30, the light is emitted from the external lens, forming a low beam light pattern and an all-weather lamp light pattern. Coupled with the light pattern formed by the light emitted by the second collimation module 20, three functional light patterns can be emitted in this embodiment, thus integrating three functions into one, sharing an external lens, and the light emission can be controlled by an electronic circuit; this embodiment further saves components and space, is conducive to the flat and miniaturized design of the overall lamp space, and the number of heat dissipation devices in the vehicle lamp is less and the cost is lower.

[0059] Referring to Figure 2 , in some embodiments, the low beam mirror 11 and the all-weather lamp mirror 12 are arranged side by side continuously. Preferably, the two are integrally formed. In this embodiment, the low beam mirror 11 and the all-weather lamp mirror 12 arranged side by side continuously save the layout space. When 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 generated by separate assembly, and the assembly accuracy is relatively high.

[0060] Further, the first 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 disposed in the light-emitting direction of each reflector one by one, and is used to collimate the light emitted by the reflector. Specifically, the collimation direction of the collimation adjustment unit 3a can be horizontal and / or vertical. When the incident light surface of the collimation adjustment unit 3a is 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 in the vertical direction, its collimation direction is the horizontal direction. When the incident light surface of the collimation adjustment unit 3a is 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 in the horizontal direction, its collimation direction is the vertical direction. The light emitted by each reflector enters the outer lens after being collimated by the corresponding collimation adjustment unit 3a for secondary collimation / focus adjustment and then emits to form a complete light pattern.

[0061] Reference Figure 2 , in some embodiments, the collimation direction of the collimation adjustment unit 3a is the first direction, and the collimation direction of the part of the outer lens module 40 corresponding to the light-emitting side of the inner lens module 30 is the second direction intersecting the first direction.

[0062] Specifically, taking the first direction as the horizontal direction and the second direction as the vertical direction as an example, for the part of the outer lens module 40 corresponding to the light-emitting side of the inner lens module 30, when its incident light surface and / or light-emitting surface is 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 in 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 40 to form the expected low beam or all-weather light pattern.

[0063] 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.

[0064] Reference Figure 2 , in this embodiment, the inner lens module 30 includes:

[0065] Inner lens I 31, in the light-emitting direction of the low beam reflector 11; and,

[0066] Inner lens II 32, arranged side by side with the inner lens I 31, and the inner lens II 32 is in the light-emitting direction of the all-weather lamp reflector 12.

[0067] 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.

[0068] 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 integration of the two parts reduces the number of parts included in the vehicle lamp, and the unified assembly of the two parts can avoid cumulative errors caused by separate assembly, with relatively high assembly accuracy.

[0069] Furthermore, the number of the low-beam reflectors 11 and the matching inner lenses I 31 can be set to more than two groups. For example Figure 2 seven low-beam reflectors 11 and the corresponding inner lenses I 31 are provided to form a better-expanded light pattern. In actual use, only one or several of the low-beam reflectors 11 and the matching inner lenses 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 lenses II 32 can be set to two groups as in Figure 2 , and the expanded area of the emitted light pattern is relatively large.

[0070] Reference Figure 2 , in some embodiments, the second collimation module 20 includes a follow-up steering mirror, and a light source is disposed at or near the focus of the follow-up steering mirror for collimating the light emitted by the light source and emitting follow-up steering light along the light-emitting direction. After the follow-up steering mirror collimates the light emitted by the light source and emits the follow-up steering light along the light-emitting direction, it enters the outer lens for adjustment to form a follow-up steering light pattern.

[0071] Of course, in addition to the above embodiments, the second collimation module 20 of the present application may also include reflectors or condensers with other lighting functions, such as fog lamp corner lights, etc., which are not limited herein.

[0072] Reference Figure 2 , in some embodiments, the outer lens module 40 includes:

[0073] A first outer lens 41, disposed on the light-emitting side of the inner lens module 30;

[0074] A second outer lens 42, disposed in front of the light-emitting direction of the second collimation module 20; a light-condensing portion 42a is formed by protruding the light-incident side surface of the second outer lens 42 toward the second collimation module 20, and grid patterns are arranged on the surface of the light-condensing portion 42a for homogenizing the light distribution;

[0075] Wherein, the light-emitting side surfaces of the first outer lens 41 and the second outer lens 42 are smoothly connected in transition.

[0076] Specifically, the second outer lens 42 plays a role in focusing adjustment in the follow-up steering function part. The light incident side surface of the second outer lens 42 bulges towards the second collimation module 20 to form a condensing part 42a, and a square or diamond-shaped grid pattern is arranged on the surface of the condensing part 42a for homogenizing the light energy distribution.

[0077] Furthermore, in this embodiment, the first outer lens 41 and the second outer lens 42 are arranged side by side and can be integrally formed. Integrating the two parts reduces the number of parts included in the vehicle lamp. The unified assembly of the two parts can avoid cumulative errors caused by separate assembly, and the assembly accuracy is relatively high. The light-emitting side surfaces of the first outer lens 41 and the second outer lens 42 are smoothly connected, forming an integral whole when viewed from the outside, with a good morphological appearance.

[0078] Reference Figure 2 and Figure 3 In some embodiments, there is a first optical path transmission space between the first outer lens 41 and the inner lens module 30, a second optical path transmission space between the second outer lens 42 and the second collimation module 20, and a light blocking structure 50 is provided between the first optical path transmission space and the second optical path transmission space.

[0079] Specifically, when the solution of the present application is implemented, the light emitted by the second collimation module 20 is likely to leak into the first optical path transmission space area, causing stray light. Therefore, the light blocking structure 50 of this embodiment is required to block the light, ensuring that the light patterns of each functional area are presented normally and do not affect each other.

[0080] The material of the light blocking structure 50 can be selected as plastic or metal parts. Further, columnar pattern surfaces 51 or leather grains in the horizontal or vertical direction need to be added to the light blocking structure 50 to reduce the reflectivity, so that the intensity of the reflected light of the light irradiated on the surface of the light blocking structure 50 is significantly weakened, avoiding the formation of strong and obvious stray light after being reflected by the surface and affecting the light-emitting light pattern.

[0081] Reference Figure 2 In some embodiments, there are two or more condensing parts 42a provided on the condensing part 42a of the second outer lens 42, and the second collimation module 20 includes two or more collimation light-emitting units 21, and the collimation light-emitting units 21 are arranged in one-to-one correspondence with the condensing parts 42a;

[0082] A split optical path transmission space is provided between the collimation light-emitting unit 21 and the corresponding condensing part 42a, and a light blocking structure 50 is provided between adjacent two split optical path transmission spaces.

[0083] The light blocking structure 50 can block light, preventing the optical paths in adjacent beam splitting optical path transmission spaces from interfering with each other. The collimated light from the collimating light output unit 21 will not be transmitted to adjacent beam splitting optical path transmission spaces or adjacent condensing parts 42a, ensuring that the light emitted by each condensing part 42a and the formed light pattern are clear and accurate, and there is no stray light affecting the light effect.

[0084] Furthermore, the light blocking structure 50 includes a light blocking plate, and the light blocking plate has a through gap 52 at the middle position in the front-back direction.

[0085] Specifically, the spatial dimension of the optical path transmission space in the front-back direction is relatively large. Correspondingly, the length of the light blocking plate is very long. When it is manufactured and formed, a demolding angle needs to be reserved in the structure, which results in inconsistent thicknesses at both ends in the front-back direction. This will directly block the light output part of the rear second collimating module 20 or the light incident surface of the front outer lens module 40.

[0086] Therefore, in this embodiment, a through gap 52 is provided at the middle position of the light blocking plate in the front-back direction, separating the light blocking plate into multiple parts. Each part divided by the gap 52 can be independently formed. Since the length of each part is short and the demolding angle is small, the probability of blocking the light output part of the rear second collimating module 20 or the light incident surface of the front outer lens module 40 can be reduced; moreover, each divided part can be independently positioned and installed, and after adjusting the installation position, it is possible to avoid blocking the light output part of the rear second collimating module 20 or the light incident surface of the front outer lens module 40.

[0087] In addition, although the light blocking plate of the present application has a through gap 52 at the middle position in the front-back direction, through experimental verification, very little light leaks between the optical path transmission spaces on both sides of the through gap 52, and the impact on the final light pattern is very small. This is probably because the light collimated and shaped by the first collimating module 10 and the second collimating module 20 has a basically stable emission direction and rarely leaks to adjacent optical path transmission spaces through the through gap 52.

[0088] Furthermore, the size of the provided gap 52 is 1 - 5 mm. Through verification, when the gap adopts this size, basically no light leaks between the optical path transmission spaces on both sides of the gap, and the finally displayed light pattern is good.

[0089] Reference Figure 4 This is another embodiment of the optical module of the present application. In this embodiment, the first collimating module 10 includes a low beam reflector 11; the inner lens module 30 includes an inner lens Ⅰ 31, which is in the light output direction of the low beam reflector 11.

[0090] Specifically, when the first collimation module 10 includes the low beam mirror 11, the light emitted by the low beam mirror 11 is adjusted by the inner lens I 31 and then emitted from the first outer lens 41, forming a low beam light pattern. Coupled with the light pattern formed by the follow-up steering light emitted by the second collimation module 20, two functional light patterns can be emitted in this embodiment, thus integrating the functions of low beam and follow-up steering into one, sharing one outer lens, and the light emission can be controlled by an electronic circuit. This embodiment saves components and space, facilitating the flat and miniaturized design of the vehicle lamp space with low beam and follow-up steering functions. Moreover, the number of heat dissipation devices in the vehicle lamp is small and the cost is low.

[0091] The present application also provides a vehicle, including the optical module described in any one of the above.
