Description

Technical Field

[0001] The present invention relates to a vehicle lamp, in particular to a vehicle lamp module. In addition, the present invention also relates to a vehicle lamp and a vehicle comprising the vehicle lamp module. Background Art

[0002] At present, different regions have different ways of driving by the side of the road. For example, some regions drive on the left side of the car, with the cab on the right side of the car (right-hand drive), while some regions drive on the right side of the car, with the cab on the left side of the car (left-hand drive). Due to the differences in driving methods in different regions, it is necessary to design low-beam lighting differently according to the differences in regional driving habits. Usually, for left-hand drive, the low-beam cut-off line is low on the left and high on the right, and for right-hand drive, the low-beam cut-off line is low on the right and high on the left.

[0003] At present, there are two main ways to achieve left-hand drive and right-hand drive on the same module. The first way is to achieve it by designing different low-beam visors. However, the same module cannot automatically switch between left-hand drive and right-hand drive modes. It is necessary to select and assemble specific visors according to different regions when assembling the module. Therefore, it is necessary to develop different molds and establish specific production lines according to the requirements of the driving mode, which is not conducive to efficient production. The second way is to use multi-pixel digital headlights. This module does not need to design a low-beam visor, and the low-beam cutoff line and inflection point are realized by turning the LED on and off. However, this module requires a large number of LED light sources, which has a great cost disadvantage, and generally the light sources are concentrated on the same circuit board. This is not only expensive, but also the heat dissipation problem is difficult to control. Summary of the invention

[0040] Description of Reference Numerals

[0041] DETAILED DESCRIPTION

[0042] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0043] First of all, it should be explained that in the following description, some directional words, such as "up", "down", "left", "right", "front", "rear", etc., are involved in order to clearly explain the technical solution of the present invention. Based on the headlight module, "front" refers to the direction indicated by the light emitting direction, "rear" refers to the direction opposite to "front", "left" refers to the left side along the light emitting direction, "right" refers to the right side along the light emitting direction, that is, the same as the left and right sides of the vehicle when it is driving normally, "up" refers to the upper side along the light emitting direction, and "down" refers to the lower side along the light emitting direction. The terms are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do 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 to the present invention.

[0044] It should be explained that the light shape refers to the projection shape of the light beam of the headlight module on the vertical plane light distribution screen 25m away from the front of the vehicle. The HH axis is the horizontal axis of the center of the light distribution screen, and the VV axis is the vertical axis of the center of the light distribution screen. "Cutoff line" is a common term in this field. As a form of low beam cutoff line, the cutoff line is the upper boundary of the light shape with upper and lower drops and inflection points on the left and right. In the low-beam light pattern of the headlight corresponding to the left-hand drive vehicle, the right side of the left-hand drive cut-off line is higher than the left side. This is because for the left-hand drive vehicle, the light pattern on the right side illuminates the lane and the right side of the lane on the road surface. The light pattern is higher, and it is brighter and farther when it shines on the road surface, while the light pattern on the left side is lower, and the boundary line of the left side light pattern (the low shoulder of the left-hand drive cut-off line) is generally located at -0.57° according to regulations. It corresponds to illuminating the left side of the lane on the road surface, and more corresponds to illuminating oncoming vehicles. In application, the illumination brightness is lower and the distance is closer than the right side. Therefore, the left-hand drive cut-off line in the present invention includes a left low shoulder 101, a left inclined section 102 and a left high shoulder 103 connected in sequence from left to right; in the low-beam light pattern of the headlight corresponding to the right-hand drive vehicle, compared with the left-hand drive cut-off line, the shape of the right-hand drive cut-off line is opposite, and it is higher on the left and lower on the right in the up and down directions. Accordingly, the right-hand drive cut-off line in the present invention includes a right low shoulder 201, a right inclined section 202 and a right high shoulder 203 connected in sequence from right to left.

[0045] The vehicle lamp module provided by the first aspect of the present invention is as follows Figures 1 to 15As shown, the headlight module is configured to be able to project and form on the light distribution screen independent left-driving inflection point light shape 100 with a left-driving cutoff line, right-driving inflection point light shape 200 with a right-driving cutoff line and a main low beam common light shape 300 with a dark area 301, wherein the left-driving cutoff line includes a left low shoulder 101, a left inclined section 102 and a left high shoulder 103 connected in sequence from left to right, and the right-driving cutoff line includes a right low shoulder 201, a right inclined section 202 and a right high shoulder 203 connected in sequence from right to left; the left-driving inflection point light shape 100 can be superimposed on the main low beam common light shape 300, so that the left low shoulder 101 and the left inclined section 102 are located in the dark area 301 to form a left-driving main low beam light shape; the right-driving inflection point light shape 200 can be superimposed on the main low beam common light shape 300, so that the right low shoulder 201 and the right inclined section 202 are located in the dark area 301 to form a right-driving main low beam light shape.

[0046] The vehicle lamp module of the present invention can be formed as follows Fig. 9 The left-hand turning point light shape 100 shown in FIG. Fig.10 The right-hand turning point light shape 200 shown in FIG. Fig.11 The main low beam common light shape 300 is shown, and the above three light shapes can be formed independently of each other on the light distribution screen, wherein the dark area 301 is located at the top of the middle position of the main low beam common light shape 300, and the lower boundary of the dark area 301 is the dark area low shoulder, and the two sides of the dark area low shoulder are transition sections extending upward from the dark area low shoulder, and the top of the transition section extends outward to form the common light shape high shoulders, and the dark area 301 formed by the dark area low shoulder and the transition section can be a rectangle, a trapezoid or other shapes, as long as it does not affect the cut-off line structure of the left-hand drive main low beam light shape and the right-hand drive main low beam light shape.

[0047] When the vehicle lamp module provided by the above basic solution of the present invention is used, for example, in the left-hand driving mode, a left-hand driving turning point light shape 100 and a main low beam common light shape 300 are formed, and the two are superimposed so that the left low shoulder 101 and the left inclined section 102 are located in the dark area 301 to form a left-hand driving mode. Fig.12 As shown in the left-hand driving main low beam light shape; if in the right-hand driving mode, the right-hand driving inflection point light shape 200 and the main low beam common light shape 300 are formed, and the two are superimposed so that the right low shoulder 201 and the right inclined section 202 are located in the dark area 301 to form as Fig.13 The right-hand drive main low beam light pattern shown in the figure can realize the intelligent switching between left-hand drive and right-hand drive modes in the same headlight module, without the need to set up production lines separately according to the requirements of different driving modes, which is conducive to improving production efficiency.

[0048] It should be noted that when the left-hand driving turning point light shape 100 is superimposed with the main low beam common light shape 300, the left high shoulder 103 is preferably connected to or partially overlapped with the high shoulder of the common light shape on the right side, so as to avoid the existence of a darker light area on the right side of the left-hand driving main low beam light shape after the two are superimposed, thereby affecting the lighting effect; similarly, when the right-hand driving turning point light shape 200 is superimposed with the main low beam common light shape 300, the right high shoulder 203 is preferably connected to or partially overlapped with the high shoulder of the common light shape on the left side.

[0049] The left-hand drive cutoff line on the left-hand drive turning point light shape 100 and the right-hand drive cutoff line on the right-hand drive turning point light shape 200 can be designed according to the application scenarios of the vehicle lights and the regulatory requirements of different countries. For example, according to the regulatory requirements of my country, the low shoulder height of the left-hand drive cutoff line and the right-hand drive cutoff line is generally located at -0.57° of the V axis, and the high shoulder height is generally located at 0° of the V axis; in the adaptive front lighting system (AFS), the low shoulder height of the left-hand drive cutoff line and the right-hand drive cutoff line can be designed according to the C-class, V-class, E-class and other modes; according to the US SAE automotive lighting standard, the low shoulder height of the left-hand drive cutoff line and the right-hand drive cutoff line is generally located at -0.4° of the V axis. Preferably, the height of the left low shoulder 101 on the light distribution screen is the same as the height of the right low shoulder 201, and the lower boundary height of the dark area 301 is not higher than the height of the left low shoulder 101. At this time, when the left-hand driving inflection point light shape 100 or the right-hand driving inflection point light shape 200 is superimposed on the main low beam common light shape 300, the cutoff line shape and height of the left-hand driving main low beam light shape or the right-hand driving main low beam light shape will not be affected by the lower boundary height of the dark area 301, so that the lighting effect of the main low beam is better when driving on the left or right side.

[0050] In some preferred embodiments of the present invention, Figure 1As shown, the vehicle lamp module includes a light source module 1, a primary optical element 2, a shading member 4 and a secondary optical element 3 which are sequentially arranged along the light emitting direction. The light source module 1 includes a left-hand driving turning point light source 11, a right-hand driving turning point light source 12 and a main low-beam common light source 13 which can be independently controlled to light up and extinguish. The shading member 4 includes a left-hand driving turning point shading portion 41, a right-hand driving turning point shading portion 42 and a main low-beam common shading portion 43. The light emitted by the left-hand driving turning point light source 11 can be emitted through the primary optical element 2 and then through the left-hand driving turning point light source 12. The point shading portion 41 shading and the secondary optical element 3 project to form a left-hand driving inflection point light shape 100; the light emitted by the right-hand driving inflection point light source 12 can be emitted through the primary optical element 2, and then be shading by the right-hand driving inflection point shading portion 42 and projected by the secondary optical element 3 to form the right-hand driving inflection point light shape 200; the light emitted by the main low-beam common light source 13 can be emitted through the primary optical element 2, and then be shading by the main low-beam common shading portion 43 and projected by the secondary optical element 3 to form the main low-beam common light shape 300. At this time, the left-hand driving turning point light source 11, the right-hand driving turning point light source 12 and the main low beam public light source 13 can be independently controlled to light up and turn off. When the left-hand driving turning point light source 11 and the main low beam public light source 13 are turned on and the right-hand driving turning point light source 12 is turned off, a left-hand driving main low beam light shape can be formed; when the right-hand driving turning point light source 12 and the main low beam public light source 13 are turned on and the left-hand driving turning point light source 11 is turned off, a right-hand driving main low beam light shape can be formed, making switching between left-hand driving and right-hand driving modes more convenient.

[0051] On the basis that the left-hand driving turning point light source 11, the right-hand driving turning point light source 12 and the main low-beam common light source 13 can be independently controlled to light up and extinguish, in some preferred embodiments of the light source module 1, the left-hand driving turning point light source 11, the right-hand driving turning point light source 12 and the main low-beam common light source 13 are respectively set as a plurality of light sources that can be independently controlled to light up and extinguish, so that the light sources in the headlight module can be dispersedly arranged on the circuit board, which is conducive to heat dissipation.

[0052] In some preferred embodiments of the primary optical element 2 of the present invention, the primary optical element 2 includes a light input portion, a light guide portion 22 and a light output portion arranged in sequence along the light output direction, the light input portion includes a light focusing structure 21 arranged in one-to-one correspondence with the light source, and a convex surface 23 corresponding to the light focusing structure 21 is formed on the light output portion, and the convex surface 23 is configured to enable the light emitted by the light source corresponding to the convex surface 23 to be projected on the light distribution screen to form a light spot of a set width and a set orientation. Specifically, the light focusing structure 21 can be a structure with an external contour in the shape of a focusing cup, or it can be other structures with a light focusing function, such as Figures 2 to 4As shown, the focusing structure 21 can be extended from the back to the front, or can be extended forward at an angle, and the extension angle of the focusing structure 21 can be independently designed according to the installation position and spatial structure of each component in the vehicle lamp module. Correspondingly, the convex surface 23 can be a convex cylindrical surface, or a convex curved surface protruding forward. When the convex surface 23 is a convex cylindrical surface, the curvature of its front surface and the distance between it and the light guide portion 22 can be designed according to the extension angle of the focusing structure 21 corresponding to the convex surface 23 or the width of the light spot required to be formed by the corresponding light source and the position of the light spot in the light shape, so as to control the corresponding light spot to the set width and orientation; when the convex surface 23 is a convex curved surface, the distance between the convex surface 23 and the light guide portion 22 can also be adjusted by adjusting the curvature of each point on the convex curved surface, and the width and orientation of the formed light spot can be controlled. The light emitted by the light source corresponding to the focusing structure 21 is focused and collimated by the focusing structure 21 and then transmitted to the corresponding convex surface 23 by the light guiding portion 22. The light is focused by the convex surface 23 and then emitted. Then, it is shielded by the shading member 4 and then emitted to the secondary optical element 3. The secondary optical element 3 projects a light spot corresponding to the light source. When a plurality of light spots are arranged and superimposed in sequence, the illumination light shape required by the vehicle lamp module of the present invention can be formed.

[0053] In some preferred embodiments of the secondary optical element 3 of the present invention, Figure 5 As shown, the secondary optical element 3 includes a plurality of light incident surfaces 31 and a light emitting surface 32. The light incident surfaces 31 are formed as convex curved surfaces corresponding to the light sources one by one and protruding toward the primary optical element 2. The light emitting surface 32 is a smooth curved surface formed by sweeping the vertical generatrix along a set curve. The vertical generatrix is ​​a convex curve protruding away from the primary optical element 2. The vertical generatrix is ​​the longitudinal section of the light emitting surface 32, and its shape and the set curve can be formed according to the requirements of the headlight shape. Each light incident surface 31 can cooperate with the light emitting surface 32 to form a convergence structure with a focus. Each convergence structure can form the refraction effect of a traditional convex lens to project the light irradiated by the primary optical element 2 to form an illumination light shape.

[0054] In some preferred embodiments of the shading member 4 of the present invention, as Figure 6 and Figure 7As shown, the main low-beam common shading portion 43 includes a left main low-beam common shading portion and a right main low-beam common shading portion, the left-driving turning point shading portion 41, the right-driving turning point shading portion 42, the left main low-beam common shading portion and the right main low-beam common shading portion are respectively arranged as a plurality of shading plates with shading structures 44, and the shading plates are arranged in a one-to-one correspondence with the light sources; the shading structure 44 corresponding to the left-driving turning point shading portion 41 and the shading structure 44 corresponding to the left main low-beam common shading portion are respectively arranged so that the light emitted by the corresponding light source can form a light shape with a left-driving cut-off line structure after projection, and the shading structure 44 corresponding to the right-driving turning point shading portion 42 and the shading structure 44 corresponding to the right main low-beam common shading portion are respectively arranged so that the light emitted by the corresponding light source can form a light shape with a right-driving cut-off line structure after projection.

[0055] It should be noted that the left-hand drive cut-off line structure and the right-hand drive cut-off line structure are light-dark boundary lines with the same structure as the above-mentioned left-hand drive cut-off line and right-hand drive cut-off line, that is, they include three parts: a low shoulder, an inclined section (the above-mentioned transition section) and a high shoulder. The left-hand drive cut-off line structure formed corresponding to the left-hand drive inflection point shading portion 41 and the right-hand drive cut-off line structure formed corresponding to the right-hand drive inflection point shading portion 42 are the above-mentioned left-hand drive cut-off line and right-hand drive cut-off line, and their inflection point positions and inclinations of the inclined sections meet the requirements of vehicle light regulations. The positions and shapes of the above-mentioned three parts of the left-hand drive cut-off line structure formed corresponding to the left main low-beam common shading portion and the right-hand drive cut-off line structure formed corresponding to the right main low-beam common shading portion are not restricted by vehicle light regulations, as long as they can cooperate with the left-hand drive cut-off line and the right-hand drive cut-off line to form a light-dark boundary line that meets the requirements of regulations. Specifically, the left main low beam common shading portion is used to form the right half light shape structure of the main low beam common light shape 300, and the right main low beam common shading portion is used to form the left half light shape structure of the main low beam common light shape 300; the shading structure 44 corresponding to the left main low beam common shading portion makes the left-driving cut-off line structure formed after the light emitted by the corresponding light source is projected, and it is not limited to the left-driving cut-off line structure in a strict sense, that is, there are no special requirements for the inclination angle and shape of its inclined segment, and it can be an inverted L-shaped structure or an inverted L-shaped structure with a certain inclination, or an inverted L-shaped structure with a certain rounded corner. Accordingly, the shading structure 44 corresponding to the right main low beam common shading portion makes the right-driving cut-off line structure formed after the light emitted by the corresponding light source is projected, which can be L-shaped or an L-shaped structure with a certain inclination, or an L-shaped structure with a certain rounded corner. At this time, the shading plates and the light sources are arranged in a one-to-one correspondence, so that the light emitted by each light source is transmitted to the corresponding convex surface 23 through the corresponding focusing structure 21, and then is shielded by the corresponding shading plate and transmitted to the secondary optical element 3 for projection, that is, the light emitted by each light source corresponding to the left-driving inflection point shading portion 41 can form a light spot with a left-driving cut-off line after being shielded by the corresponding shading plate, and multiple light spots with left-driving cut-off lines are superimposed to form a complete left-driving inflection point light shape 100; each light source corresponding to the right-driving inflection point shading portion 42 can form a light spot with a left-driving cut-off line after being shielded by the corresponding shading plate. A light spot with a right-driving cutoff line is formed, and multiple light spots with right-driving cutoff lines are superimposed to form a complete right-driving inflection point light shape 200; each light source corresponding to the left main low-beam common shading part can form a light spot with a left-driving cutoff line structure after being shielded by the corresponding shading plate, and each light source corresponding to the right main low-beam common shading part can form a light spot with a right-driving cutoff line structure after being shielded by the corresponding shading plate, and all the light spots formed corresponding to the left main low-beam common shading part and the right main low-beam common shading part are superimposed to form a complete main low-beam common light shape 300 with a dark area 301.

[0056] In order to improve the lighting effects of the left-driving inflection point light shape 100 and the right-driving inflection point light shape 200, preferably, the left-driving cutoff line inflection points of each light spot forming the left-driving inflection point light shape 100 overlap, and the right-driving cutoff line inflection points of each light spot forming the right-driving inflection point light shape 200 overlap.

[0057] It should be explained that the formation method of the left-hand driving turning point light shape 100 and the right-hand driving turning point light shape 200 in the present invention can be applied to the AFS function of the vehicle lamp separately, for example, Fig.16 As shown, the left-hand driving cutoff line inflection points of each light spot forming the left-hand driving inflection point light shape 100 are set to be non-overlapping. In the left-hand driving mode, the change of the inflection point position on the complete left-hand driving inflection point light shape 100 can be achieved by turning on and off each left-hand driving inflection point light source 11, thereby realizing the follow-up steering function of the vehicle light module when driving left; the change of the inflection point position on the right-hand driving inflection point light shape 200 can also be achieved in the same way, thereby realizing the AFS follow-up steering function of the vehicle light module when driving right.

[0058] In some preferred embodiments of the shading member 4 of the present invention, the shading member 4 is configured to be movable in the up and down directions. By the overall up and down translation of the shading member 4, the height position control of the left-hand drive cut-off line structure and the right-hand drive cut-off line structure can be achieved. When the shading member 4 translates upward, the left-hand drive cut-off line structure and the right-hand drive cut-off line structure become lower; when the shading member 4 translates downward, the left-hand drive cut-off line structure and the right-hand drive cut-off line structure become higher, thereby achieving the height change of the cut-off line required by the C-level, V-level, E-level and other modes in the above-mentioned AFS, and meeting the cut-off line requirements of the SAE low beam light shape.
