[0003] At present, the autonomous driving indicator lights and turn signal lights are combined together, but the settings of each light have not been carefully studied. Generally, many LED lights are set to meet the regulatory requirements for the visible area and luminous intensity of the autonomous driving indicator lights, resulting in high costs. Utility Model Content
[0004] In view of the shortcomings or deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a car side turn signal light with an integrated automatic driving indicator light, which not only achieves better heat dissipation by diffusion and adding PCBA boards on both sides, but also achieves the effect of meeting the required visible area and luminous intensity at a low cost.
[0005] In order to solve the above technical problems, the utility model has the following structure:
[0006] A car side turn signal lamp with integrated automatic driving indicator lamp, comprising a housing, a second PCBA board mounted on the housing, a diffusion layer and a lens layer, wherein the lens layer is fixed to the diffusion layer, a turn signal lamp and an automatic driving indicator lamp are arranged on the second PCBA board, and a gap is formed between the turn signal lamp and the automatic driving indicator lamp;

[0009] The driving circuit on PCBA board 2 controls the turning on and off of the turn signal light and the automatic driving indicator light. The diffusion layer causes the emitted light spot to diffuse to the lens layer in the form of straight line light, and then is refracted by the lens layer and transmitted to the light emitting surface of the outer shell in the form of surface light emission, so as to form a turn signal light or automatic driving indicator light with the surface as the light emitting area.
[0010] In order to increase the dynamic loss effect of the side turn signal or the automatic driving indicator light, a voltage stabilizing circuit is also provided on the second PCBA board, and the voltage stabilizing circuit is used to adjust the driving circuit voltage to form a dynamic flowing car side turn light.

[0012] In order to facilitate the final dispersion of light, the second circular arc is an expanded cavity that diffuses from the center toward both sides, and the opening of the second circular arc is arranged toward the first circular arc.
[0013] After being guided by the third arc and the fourth arc, the turn signal lamp and the automatic driving indicator lamp on the second arc form an arc-shaped luminous area with a horizontal angle area of 5°-60° in the horizontal direction, and the light intensity value is 0.6cd-280cd.
[0014] In order to meet better requirements, PCBA board 1 and PCBA board 3 at both ends of PCBA board 2 are respectively provided with auxiliary lights, and the auxiliary lights adjust the horizontal angle of the fan-shaped light-emitting area to 0°-20°.
[0015] Furthermore, the vertical angle of the arc-shaped light-emitting area is 15°.
[0016] For better distribution, the turn signals and the automatic driving indicator lights are both LED lights, and the turn signals and the automatic driving indicator lights arranged at intervals form an LED light string, and the LED light string is arranged parallel to the diffusion layer and close to the diffusion layer.
[0017] In order to meet the requirements of two different systems at the same time, the spacing gap along the assembly surface of the PCBA board is not less than 1 mm.
[0018] During assembly, two ends of the assembly cavity are provided with limit slots, and the PCBA board 1 and PCBA board 3 are clamped in the limit slots.
[0019] Compared with the prior art, the advantages of the utility model are:
[0020] The automobile side turn signal lamp with integrated automatic driving indicator lamp of the utility model not only integrates the automatic driving indication function and the steering function into the side turn signal lamp by adding a diffusion layer and a lens layer, thereby improving the degree of integration, but also adds two PCBA soft boards to transform the LED light source into a surface light source, which has an obvious prompting effect and improves driving safety.

[0027] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.
[0028] It should be noted that in the description of the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are simplified descriptions for the convenience of describing the present invention only, and do not mean that the elements indicated must have a specific direction, be constructed and operated in a specific direction, and should not be construed as limitations on the present invention.
[0029] The automobile turn signal lamp of the utility model is suitable for being integrated (installed) on the exterior rearview mirror of the automobile.
[0030] like Figure 1-3 As shown, a car side turn signal with integrated automatic driving indicator light comprises a shell 10, a PCBA board 20 mounted on the shell 10, a diffusion layer 30 and a lens layer 40, wherein the lens layer 40 is fixed to the diffusion layer 30, and a turn signal 21 and an automatic driving indicator light 22 are provided on the PCBA board 20, and a spacing gap 23 is formed between the turn signal 21 and the automatic driving indicator light 22; in the specific assembly, the shell 10 protrudes toward the PCBA board 2 to form an assembly cavity, firstly, the PCBA board 2 having a PCBA board 1 23 and a PCBA board 3 24 composed of soft boards at both ends are fixed to the bottom of the assembly cavity, and then a limiting column 50 is arranged in the assembly cavity, so that the diffusion layer on the outer side of the PCBA board 2 is fixedly connected with the limiting column 50, and at this time, the PCBA board 1, the PCBA board 2 and the PCBA board 3 are located between the diffusion layer and the assembly cavity, and then the lens layer 40 is adhered to the outer side of the diffusion layer 30.
[0031] The usage process of this embodiment is as follows:
[0032] The driving circuit 25 on the PCBA board 20 controls the turning lights 21 and the automatic driving indicator light 22 to turn on and off. The diffusion layer 30 allows the emitted light spots to diffuse onto the lens layer 40 in the form of straight line light, and then are refracted by the lens layer 40 and transmitted to the light emitting surface of the housing 10 in the form of surface light, so as to form turning light with the surface as the light emitting area.
[0033] In this embodiment, a voltage stabilizing circuit 26 is further provided on the second PCBA board 20, and the voltage stabilizing circuit 26 is used to adjust the voltage of the driving circuit 25 to form a dynamic flowing car side turn light or automatic driving indicator light. In this embodiment, the voltage stabilizing circuit is arranged in the middle and upper part of the second PCBA board, and is misaligned with the LED light.
[0034] Refer to the attached Figure 1 As shown, in order to match the assembly shell of the turn signal lamp for easy assembly, the housing 10, PCBA board 20, diffusion layer 30 and lens layer 40 are parallel to each other and assembled in sequence to form a first arc, a second arc, a third arc and a fourth arc respectively. The arc structure is beautiful, and the arc design has a good effect on the diffusion and guidance of light.
[0035] In use, the second arc is an expanded cavity that spreads from the center to both sides, and the opening of the second arc is arranged toward the first arc. Therefore, the four arcs are all expanded cavities, and other structures are also convenient for assembly directly from the middle to both sides, with high assembly efficiency.
[0036] Specifically, after the turn signal and the automatic driving indicator light on the second arc are guided by the third arc and the fourth arc, an arc-shaped luminous area with a horizontal angle area of 5°-50° is formed in the horizontal direction.
[0037] Specifically, PCBA board 1 23 and PCBA board 3 24 at both ends of PCBA board 2 20 are respectively provided with auxiliary lights, and the auxiliary lights adjust the angle of the fan-shaped light-emitting area to 5°-60° and the light intensity value is 0.6cd-280cd. In this embodiment, multiple LEDs are linearly arranged on the soft board PCBA. In order to share the heat dissipation requirements of the PCBA soft board, the control logic circuit is transferred to the conventional hard board PCBA. Furthermore, in the utility model, by setting LED lights in multiple places, the impact on the life of a single PCBA board is reduced, and the heat dissipation is good.
[0038] In order to better meet the requirements of regulations, the vertical angle of the arc-shaped light-emitting area is 15° up and down to meet the regulations. Specifically, it is rotated 15° upward from the horizontal direction to 15° downward from the horizontal direction, so that the overall lighting effect is better.
[0039] In actual use, the turn signal lights and the automatic driving indicator lights are both LED lights. The turn signal lights and the automatic driving indicator lights arranged at intervals form an LED light string, and the LED light string is arranged parallel to the diffusion layer 30 and close to the diffusion layer 30 .
[0040] Specifically, in order to ensure better assembly, the spacing gap along the assembly surface of the PCBA board is not less than 1 mm.
[0041] In this embodiment, by setting interval gaps and optimizing the structure including adding a diffusion layer, etc., the number of LED lamps can be reduced, the cost can be reduced, and popularization suitable for automobile development can be achieved.
[0042] In order to realize the assembly of the soft board, limit slots 11 are provided at both ends of the assembly cavity, and the PCBA board 1 23 and the PCBA board 3 24 are clamped in the limit slots 11.
[0043] As automatic assisted driving becomes more and more popular, people pay more and more attention to its safety. In order to improve the safety of other vehicles and pedestrians, the regulations on automatic assisted driving indicator lights are about to be officially released, and the installation position of automatic assisted driving indicator lights has clear regulations. The automatic driving indicator lights integrated in the front fenders of cars have a certain degree of obstruction of vision and cannot provide warning functions for pedestrians and moving vehicles more effectively and safely. The present invention combines the automatic driving indicator lights with traditional turn signals and integrates the two-color indicator lights into the rearview mirror, so as to achieve the purpose of being easy for other vehicles to observe and improve driving safety.
[0044] In the present invention, a diffusion layer 30 formed by a PCBA soft board and a diffusion sheet is used to diffuse multiple LED light sources into a surface light source, thereby realizing the combination of the autonomous driving indicator light and the traditional side turn signal light. By combining multiple LEDs with a diffusion sheet, the lighting effect is presented as a uniform effect that fills the luminous area of the rearview mirror, and by adjusting the operation of LEDs of different colors, an amber car turn signal light and a cyan autonomous driving indicator light are realized. However, due to regulatory restrictions, these two colors of lights will not light up at the same time, and the working priority of the side turn signal light is greater than that of the autonomous driving indicator light. The advantage of the present invention is that it realizes dual functions and a uniform lighting effect.
[0045] In order to further meet the regulatory requirements for the visible area and luminous intensity of the autonomous driving indicator light, this embodiment is to meet the regulatory requirements while ensuring the consistency of the lighting effect and provide a reasonable optical solution. To solve this problem, multiple LEDs need to be linearly arranged on the soft board PCBA (i.e., PCBA board 1 23 and PCBA board 3 24 at both ends), and to share the heat dissipation requirements of the PCBA soft board, the control logic circuit is transferred to the conventional hard board PCBA (i.e., PCBA board 2 20).
[0046] In use, this embodiment uses a diffuser and a soft board PCBA to transform the LED light source into a surface light source, while providing an optical solution with a uniform lighting effect. At the same time, it can adapt to different forms of A-side shapes provided by the host manufacturer. Compared with traditional solutions, it has fewer limitations and the effect can be accepted by the host manufacturer.
[0047] In actual use, the vehicle body transmits the electrical signal and the start signal to the rearview mirror assembly through the interface, and the rearview mirror assembly transmits the signal to the turn signal. When the car turns, the turn signal is input, and the steering electronic components on the electronic board work to output an amber light source. The amber light source transmits the light to the light-emitting surface of the rearview mirror through the Diffusion and LENS in the present invention, and finally presents amber light on the surface; when the car enters the automatic driving state, the automatic driving signal is input, and the automatic driving electronic components on the electronic board work to output a blue-cyan light source. The blue-cyan light source transmits the light to the light-emitting surface of the rearview mirror through the Diffusion and LENS in the present invention, and finally presents blue-cyan light on the surface.
[0048] Use the tooling to interference fit PCBA 1 and PCBA 3 in the designated slots of the Housing (i.e., shell). Put PCBA 3 into the limiting hole of the Housing, and connect its port with PCBA 1. Place the Diffusion (i.e., diffusion layer) in the limiting column of the Housing. Fix the limiting column with hot riveting to fix PCBA3 and Diffusion. Finally, perform vibration friction welding on the LENS and the Housing through the tooling to complete the assembly.
[0049] In this embodiment, a limiting hole is further provided on the housing, so that a circular hole is also provided on the housing in the length direction at a relative position to the flexible board, and the limiting hole is combined with the circular hole to ensure the accurate relative position of the PCBA and the housing.
[0050] The optical principle of the utility model is as follows:
[0051] 1. A single LED light propagates in a straight line through the air and enters the diffuser. Due to the diffusion factor in the diffuser, the light path can be changed into irregular straight line propagation.
[0052] 2. Different proportions of diffusion factors have different diffusion effects on light. The more diffusion factors there are, the better the diffusion effect is, but the worse the light efficiency is.
[0053] 3. The irregular light in the diffuser is refracted into the air and propagates in a straight line;
[0054] 4. The light enters the LENS through refraction, propagates in a straight line inside, and finally refracts through the LENS surface;
[0055] 5. Since the typical radiation values (light-emitting half-angle) of different types of LEDs are different, the gap between the LED light-emitting center and the diffuser affects the uniformity of the lighting effect. The smaller the gap between the two, the more difficult it is for the LED light to be diffused by the diffuser. Conversely, the larger the gap between the two, the easier it is for the light to be diffused, and the better the uniformity of the lighting effect.
[0056] 6. The larger the gap between LEDs with the same function, the greater the uniformity, and vice versa, the better the uniformity, due to the limited diffusion angle of LED light.
[0057] This embodiment adopts the above principle and cleverly arranges the structure, thereby achieving the effect of eliminating LED lamps and providing a low-cost surface light source.
[0058] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not deviate from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
