Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile, concretely relates to an electronic light-adjusting high and low beam module, a searchlight assembly and an automobile. BACKGROUND
[0002] Due to manufacturing tolerances, deviations inevitably occur in the installation process of the automobile lamp and the vehicle body. According to the design, the optical axis of the high and low beam module should be parallel to the ground; however, these tolerances result in an included angle between the optical axis of the high and low beam module and the ground. According to relevant regulations, the adjustment angle of the optical axis of the module needs to meet the requirement of ±2 degrees, and some automobile manufacturers set a more extensive standard, i.e. ±3 degrees or -5 degrees to +3 degrees.
[0003] In order to meet these light-adjusting requirements, the prior art adopts a scheme of installing the high and low beam module on an adjustable support and equipping it with a light-adjusting motor. At the same time, in order to ensure the realization of the light-adjusting function, the internal space of the automobile lamp must also meet the space requirement of the high and low beam module within the light-adjusting angle range. However, due to the configuration of the light-adjusting support and the light-adjusting motor, this technical scheme also has obvious disadvantages: one is high cost, and the other is the increase of the internal space requirement of the automobile lamp.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] The scheme provides an electronic light-adjusting high-low beam module. When a vehicle is detected, the deflection angle of the high-low beam module of the vehicle is measured, the lighting area of the electronic light-adjusting high-low beam module is adjusted based on the measured deflection angle, and the installation deviation is compensated.
[0037] Referring to Figure 1 An electronic light-adjusting high-low beam module comprises:
[0038] A partitionable bright point light source 100 is composed of N individually controllable sub-light-emitting surfaces in a matrix distribution, and N is a positive integer not less than 2. The structure of the partitionable bright point light source 100 can be seen from Figure 2 , Figure 2 Each small rectangular area can be regarded as an individually controllable sub-light-emitting surface, and the lighting state of the sub-light-emitting surface can be controlled by a related controller.
[0039] A light source controller 200 is connected to the controller of each sub-light-emitting surface through a control instruction output interface, and is used to generate and output a control signal for controlling the lighting state of the sub-light-emitting surface. The control signal output by the light source controller 200 is used to control the overall lighting of each individually controllable sub-light-emitting surface group in the required lighting area of the partitionable bright point light source 100. The control signal output by the light source controller 200 is different for different lighting conditions required by the user. Different control signals correspond to different required lighting areas of the partitionable bright point light source 100. The corresponding relationship between each control signal and the corresponding lighting area is pre-configured.
[0040] A light condensing module 300 is used to condense the light emitted by the partitionable bright point light source to generate a convergent light shape.
[0041] A diffusion module 400 is used to diffuse the light emitted by the partitionable bright point light source to generate a diffused light shape.
[0042] The focusing module is used to generate high beam rays, and the diffusion module is used to generate low beam rays. The focusing module and the diffusion module can generate different light patterns according to different requirements. The focusing module for generating converging light patterns can be composed of a single lens or a multi-lens system. The light patterns generated by the focusing module can include converging high beam, converging low beam, and low beam with a shifting cutoff line. The diffusion module 400, which generates diffused light patterns, produces a larger light pattern range compared to the light pattern generated by the focusing module 300, capable of meeting a wider illumination range. For example, it can meet the light pattern width requirements of 40 degrees left and right or 30 degrees left and right. These light patterns can include low beam widening light patterns and high beam widening light patterns with a horizontal cutoff line. The focusing module 300 and the diffusion module 400 can be the focusing module and diffusion module in existing vehicle searchlights.
[0043] In the existing scheme, the area to be illuminated in the partitioned bright spot light source 100 varies depending on the light pattern. When a high beam pattern is required, the illuminated area of the partitioned bright spot light source 100 is as follows: Figure 3 As shown, when a near-beam shape is required, the illuminated area of the partitioned bright spot light source 100 is as follows: Figure 4 Or as shown in 5, when Figure 5 After the individual controllable sub-emitting surfaces in the illuminated area of the partitionable bright spot light source 100 are illuminated, the light generated by the optical system at this time is as follows: Figure 6 As shown. If the installation deviation meets the requirements, the horizontal cutoff line of the broadened beam pattern produced by the diffusion module will be located within 2° below the horizontal line (optical axis). Figure 6 The near-beam converging beam pattern shown is Figure 7 The complete near-light pattern formed by superimposing the displayed light patterns is as follows: Figure 8 As shown, when the vehicle turns on its high beams, the light pattern generated solely by the converging module is as follows: Figure 9 As shown, the high beam generated solely by the diffusion module resembles... Figure 10 As shown, the high beam pattern generated by the convergence module and the diffusion module is as follows: Figure 11 As shown.
[0044] Due to installation tolerances, there are deviations between the installation of automotive lights and the vehicle body. This can cause the cutoff line of the broadened light pattern produced by the diffusion module to rise from 2 degrees below the horizontal line to 1 degree below the horizontal line, as shown below. Figure 12 When the high beam is activated, the beam patterns of both the low and high beams generated by the diffusion module also increase by 1 degree. At this time, because the partitionable bright spot light source in this application consists of N individually controllable sub-emitting surfaces distributed in a matrix, the illuminated area can be pre-adjusted based on installation deviations between the car headlights and the car body. Figure 13As shown, when the cutoff line can be raised from the 2-degree position below the horizontal line to the 1-degree position below the horizontal line, the lower boundary of the spotlight light pattern generated by the lifting spotlight module is raised so that the lower boundary reaches the 1-degree position below the horizontal line. When the cutoff line of the spread light pattern generated by the diffusion module can be raised from the 2-degree position below the horizontal line to the 4-degree position below the horizontal line, as shown below Figure 14 When the high beam is turned on, the low beam and high beam light patterns generated by the diffusion module are also lowered by 2 degrees. At this time, since the zonal bright point light source in the present application is composed of N individually controllable sub-light emitting surfaces distributed in a matrix, the installation deviation based on the mounting of the automobile lamp and the vehicle body can be adjusted in advance, and the bright point region is adjusted, as shown in Figure 15 As shown, when the cutoff line can be raised from the 2-degree position below the horizontal line to the 4-degree position below the horizontal line, the lower boundary of the spotlight light pattern generated by the lifting spotlight module is raised so that the lower boundary reaches the 4-degree position below the horizontal line. Thus, the electronic dimming high-low beam module can adapt to various installation deviations.
[0045] As can be seen, since the zonal bright point light source in the present application is composed of N individually controllable sub-light emitting surfaces distributed in a matrix, each sub-light emitting surface is individually controllable. Therefore, the light emitting region of the zonal bright point light source can be adjusted according to the installation error so that the region matches the installation error. In this way, there is no need to install a moving mechanism, a dimming motor, and a dimming support lamp in the lamp, greatly saving the space in the lamp and reducing the manufacturing cost of the lamp.
[0046] In the technical solution disclosed in the present embodiment, the type of the zonal bright point light source can be selected according to user needs. For example, in the technical solution disclosed in the present embodiment, the zonal bright point light source can be an LED light source, and the LED light source is individually controlled by N individually controllable LED light emitting elements, and each LED light emitting element is an individually controllable sub-light emitting surface.
[0047] In the technical solution disclosed in the present embodiment, the light source controller has a dimming interface for being connected to a dimming angle controller through a data line. The dimming angle controller can belong to the electronic dimming high-low beam module or be a separate device independent of the electronic dimming high-low beam module. The dimming angle controller is used to output a dimming instruction to the light source controller, and the dimming instruction is used to control the bottom edge of each target light pattern to deviate to a target direction. The target light pattern is a converging light pattern generated by the spotlight module below the optical axis. For example, the target light pattern is Figure 5 , Figure 12 or Figure 14The bottom edge of the target light shape refers to the edge of the target light shape far from the optical axis. In the present scheme, the dimming instruction is used to control the bottom edge of the target light shape to deviate to a target direction (upward or downward), which essentially belongs to the modification of target data, i.e., the coordinates of the bottom edge of the target light shape. That is, the coordinates data of the bottom edge of the target light shape in the light source controller is modified by the dimming angle controller, so that the bottom edge of the target light shape deviates to a target direction (upward or downward). Thus, this part can be completely realized by the existing scheme and does not involve method improvement.
[0048] Further, the dimming angle controller can also be integrated into the electronic dimming high-low beam module. It can have two adjustment buttons, i.e., an upward adjustment button and a downward adjustment button. When the user triggers the upward adjustment button, the value of the bottom edge of the target light shape is adjusted to the direction close to the optical axis by modifying the parameters stored in the dimming angle controller for representing the bottom edge of the target light shape. When the user triggers the downward adjustment button, the value of the bottom edge of the target light shape is adjusted to the direction far from the optical axis by modifying the parameters stored in the dimming angle controller for representing the bottom edge of the target light shape.
