[0055] The utility model will be described in detail below in combination with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that, for those skilled in the art, without departing from the concept of the utility model, a number of changes and improvements can be made. These all belong to the protection scope of the utility model.
[0056] Example 1:
[0057] As shown in Figure 2 and Figure 3 , the present embodiment provides a car lamp module capable of realizing pixel lightening, comprising: a light source 1 and a plurality of shielding structures 6; the plurality of shielding structures 6 are arranged corresponding to the light emitting area of the light source 1, the plurality of shielding structures 6 correspond to different areas of the light emitting area respectively, and the area corresponding to a single shielding structure 6 is a pixel area of the light emitting area; when the light emitting area is normally lighted: the plurality of shielding structures 6 are all located outside the pixel area, and the light emitted by the light source 1 is emitted through the light emitting area; when one or more pixel areas of the light emitting area need to be extinguished: the shielding structure 6 corresponding to the pixel area to be extinguished is located in the pixel area, and the light is shielded. The car lamp module further comprises: a plurality of driving assemblies 8; the shielding structure 6 and the driving assembly 8 are one-to-one drivingly connected, and the driving assembly 8 can drive the shielding structure 6 to move into and / or move out of the pixel area. The plurality of shielding structures 6 are arranged along the horizontal direction; when the plurality of shielding structures 6 are all located in the pixel area, the plurality of shielding structures 6 can completely cover the entire light emitting area.
[0058] Take 12 pixel areas as an example. As shown in Figure 7 , it is an effect schematic diagram of all pixel areas not being shielded, and the white block area is the pixel area. As shown in Figure 8 , it is an effect schematic diagram when two pixel areas are shielded, and the black block area is the area where the shielding structure is located.
[0059] The driving component 8 is an electromagnetic coil component. When the current flowing within the electromagnetic coil component is in a first current direction, the electromagnetic coil component generates an attractive force on the blocking structure 6, driving the blocking structure 6 to move out of the pixel area and place it outside the pixel area. When the current flowing within the electromagnetic coil component is in a second current direction opposite to the first current direction, the electromagnetic coil component generates a repulsive force on the blocking structure 6, driving the blocking structure 6 to move into the pixel area and place it inside the pixel area. The automotive headlight module also includes a limiting bracket structure 7. When the blocking structure 6 moves out of and / or into the pixel area, the limiting bracket structure 7 limits the blocking structure 6. The limiting bracket structure 7 can be a baffle set on a fixed frame. When the blocking structure 6 moves to the baffle position, the baffle blocks the movement of the blocking structure 6, thereby limiting the blocking structure 6 and placing it in a preset position.
[0060] Driven by attraction and repulsion, the stability of the shielding structure can be better guaranteed. If no force is applied to the shielding structure, then the slight vibration of the car during driving will cause the shielding structure to shake, which will affect the light output.
[0061] The automotive headlight module also includes an optical structure 4 and an outer lens 5. When the light-emitting area is normally illuminated, the light emitted by the light source 1 is adjusted by the optical structure 4, passes through the light-emitting area to the outer lens 5, and then exits through the outer lens 5. In this embodiment, the optical structure 4 is a lens structure 402; the light source 1 is placed vertically, and the light-emitting direction of the light source 1 is horizontal. The light source 1 is integrated on the PCBA board 2, and the PCBA board 2 is integrated on the heat sink 3.
[0062] This embodiment also provides a car, including the above-described car headlight module capable of enabling pixel on / off switching.
[0063] like Figure 1 The image shown is a rendering of ADB technology. When vehicles approach from the same direction or from the opposite direction, the driver's area of the corresponding vehicle will be turned off to prevent glare.

A single driving component 8 includes: a lower driving component 801 and an upper driving component 802; the lower driving component 801 is drivingly connected to the lower occlusion structure 601, and the lower driving component 801 can drive the lower occlusion structure 601 to move into and / or out of the lower pixel area; the upper driving component 802 is drivingly connected to the upper occlusion structure 602, and the upper driving component 802 can drive the upper occlusion structure 602 to move into and / or out of the upper pixel area.
[0069] The structures of the lower driving component 801 and the upper driving component 802 are the same as those of the driving component 8 in Embodiment 1. The driving method of the lower driving component 801 to the lower blocking structure 601 and the driving method of the upper driving component 802 to the upper blocking structure 602 are the same as those of the driving component 8 in Embodiment 1.
[0070] Example 4:
[0071] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that a single occlusion structure 6 includes: a lower occlusion structure 601 and an upper occlusion structure 602; the lower occlusion structure 601 and the upper occlusion structure 602 are respectively set for the upper pixel area and the lower pixel area of a single pixel area; when the pixel area is normally lit: the lower occlusion structure 601 is located outside the lower pixel area, and the upper occlusion structure 602 is located outside the upper pixel area; when it is necessary to turn off the lower pixel area and / or the upper pixel area of the pixel area: the lower occlusion structure 601 is located inside the lower pixel area and / or the upper occlusion structure 602 is located inside the upper pixel area.

[0073] As shown in Figure 9 , the left and right two pixel areas are completely shielded, and the middle two pixel areas are only shielded from the upper pixel area.
[0074] Embodiment 5:
[0075] Those skilled in the art can understand this embodiment as a more specific description of Embodiments 1-4.
[0076] This embodiment provides a self-adaptive intelligent headlamp with fewer LED counts, low cost, and space saving.
[0077] The difficulty of implementing ADB by electromagnet: ordinary high-low light switching is only a piece of light shielding piece, ADB has multiple pieces, when implementing adaptive high beam, the shielding structure needs to work continuously, and the implementation difficulty is greater. In the background technical patent document, when implementing the high beam function, it does not need to work, and in this embodiment, the shielding structure 6 and the electromagnetic component 8 are made into standard modules, and the setting is more free. If a fault occurs later, the cost of replacing the standard module is lower.
[0078] Compared with the function switching between ordinary high-low light by electromagnetic drive, this embodiment is to realize adaptive high beam by electromagnetic drive. In terms of function implementation, the former is function switching, and the latter is single function upgrade. The purposes of implementation are different. In terms of technical difficulty, the former is a choice between two, either low beam or high beam, 0 or 1 selection. The size and implementation function of the functional components are relatively simple. While in this embodiment, adaptive high beam is realized by electromagnetic drive, which is a single function upgrade, i.e. advanced high beam. The number and size of the drive and the complexity of the system are not linearly cumulative.
[0079] As shown in Figure 7 and Figure 8 , this embodiment takes the division of the light emitting area into 12 pixels as an example.
[0080] The self-adaptive intelligent headlamp of this embodiment includes a light source 1, a PCBA board 2, an outer lens 5, an optical structure 4, a shielding structure 6, and an electromagnetic component 8.
[0081] The adjustable shielding structure can be composed of many pieces according to the optical design requirements. Among them, the shielding structure 6 and the electromagnetic component 8 are made into standard modules, and according to different pixel number requirements, different standard module quantities can be freely matched. For example, 12 pixels can be selected by 12 standard modules.
[0082] The shielding structure can be moved and controlled by the energized coil. When the energized direction is the first current direction, the energized coil generates an attractive force on the shielding structure, driving the shielding structure to move downward, and the shielding structure is located below the light-emitting area. The light emitted from the LED on the PCB enters the optical structure (which can be a through-lens or reflected by a reflecting bowl), and a cutoff line is formed by the shielding structure. At this time, the optical system generates a complete high beam or low beam light pattern. When the same direction or opposite direction of the oncoming vehicle is needed, the energized direction of the energized coil of the shielding structure in the corresponding area is adjusted to the second current direction opposite to the first current direction, so as to generate a repulsive force, which lifts up several shielding structures in the corresponding area. At this time, the light shielding piece is in a vertical position, so the light cannot pass through, and the light is shielded, so that a dark area is generated in the corresponding light pattern area, thereby realizing the ADB function and achieving the effect of anti-dazzling.
[0083] As shown in Figure 7 , it can be 12 shielding pieces. When all the shielding pieces are in a horizontal position, all the high beams are normally lit. When there is an oncoming or same direction vehicle, the effect is as shown in Figure 8 , the shielding pieces in the corresponding area are in a vertical position, and part of the high beam area is extinguished, thereby realizing the ADB function and achieving the effect of anti-dazzling.
[0084] Figure 3 For a projection system, Figure 4 for a reflection system, Figure 5 for an upper and lower two-layer reflection system, Figure 6 for an upper and lower two-layer projection system.
[0085] Further, according to the number of shielding pieces of the adjustable shielding structure, different pixel numbers of the system can be realized, and the design is more free.
[0086] Further, according to the optical design requirements, the shielding structure can be made into two layers, and the light-out area can be further refined. The effect is as shown in Figure 9 . Through the standard modular structure, the required light-out area can be freely combined to realize various anti-dazzling effects and improve efficiency.
[0087] Further, the present embodiment is applicable to ordinary high beams, low beams, high-low beam integration, ADB, left and right rudders, etc.
[0088] Further, the light source can be a patch LED integrated on a PCBA or integrated on a heat sink, connected to the PCB board by a metal wire, a laser light source, or other light source types according to actual needs.
[0089] Further, the placement position of the light source assembly in the entire vehicle lamp module space can be horizontal or vertical according to the specific optical system, such asFigure 3 and Figure 4 As shown in FIGS. 1 and 2, the light source is placed in different positions in two different optical systems.
[0090] Further, the shielding structure itself can be made of iron or the like, and the energized coil generates a magnetic force after being energized, which lifts up a certain piece of shielding structure. Alternatively, the shielding structure is not made of iron, and the energized coil generates a magnetic force to push the mechanical arm, which in turn pushes the shielding structure. The specific implementation mode is determined according to the actual space and situation.
[0091] Further, the shielding structure can also be a plastic part, and a magnet is embedded in the plastic part.
[0092] Further, the electromagnetic generated by the coil can be shielded by adding a shield structure.
[0093] Embodiment 6:
[0094] Those skilled in the art can understand this embodiment as a more specific description of embodiments 1-4.
[0095] The car light module of this embodiment comprises a light source assembly, an outer lens for realizing optical performance, an optical structure for realizing high and low beams in cooperation with the outer lens, an adjustable shielding structure, and a frame for fixing the above components. The light source assembly of the module is located at the innermost end of the entire structure, and the light emitted by the light source assembly passes through the optical structure for realizing high and low beams in cooperation with the outer lens to form a complete optical system. The adjustable shielding structure is located in the middle of the entire system, and different shielding structures are controlled to open or shield the area that needs to be extinguished. The frame is used to fix each component of the entire module to make it a whole, and to cooperate with the shielding structure.
[0096] The entire car light module realizes a basic high beam or low beam light pattern through the inner and outer lenses, the light source assembly, the outer lens for realizing optical performance, and the optical structure for realizing high and low beams in cooperation with the outer lens. It can also be a module integrating high and low beams. The adjustable shielding structure is composed of several pieces, and the magnetic force generated by the energized coil controls its movement. When the ADB function of the high beam is to be realized, when a car drives in the opposite or same direction, the signal is given to the corresponding coil to generate a magnetic force to push the shielding structure at the corresponding position to extinguish the light in that area.
[0097] Further, the number of adjustable shielding structures can be changed according to the design requirements of the light pattern, i.e. to adjust the number of pixels of different high and low beams. For example, 12, 24, etc.
[0098] Further, the cut-off line light pattern of the low beam can also be realized by the work of different shielding pieces.
[0099] Further, the light source assembly includes a light source, such as an LED light source or a laser light source, and a plurality of electronic components fixed on the PCB, and a heat dissipation structure component behind the PCB. It can also be directly integrated on the heat dissipation structure component. The placement position of the light source assembly in the entire vehicle lamp module space can be horizontal or vertical according to the specific optical system, such as Figure 3 and Figure 4 , which are two different optical systems, and the placement position of the light source is different.
[0100] Further, the outer lens for realizing the optical performance and the optical structure for realizing the high beam and low beam with the outer lens realize the high beam and low beam. It is an optical component for realizing the high beam and low beam, and the outer lens is the outer lens of the module. The implementation method inside can be selected according to the actual situation, such as a reflector bowl or a lens. The optical system is adjusted according to the actual situation, such as Figure 3 and Figure 4 , which are two different optical systems.
[0101] Further, the adjustable shielding structure includes a shielding structure, which includes a shielding structure composed of a plurality of pieces. The shielding structure can be moved. When the shielding structure is located below, the lower part is controlled by the suction force generated by the energized coil. The shielding structure can be made of iron. The energized coil contains an iron core. When the energized direction is the first current direction, the shielding structure is attracted by the iron core. At this time, the shielding structure is located below the module. At this time, the optical system generates a complete high beam or low beam. When the energized direction of the energized coil corresponding to a piece of shielding structure is adjusted to the second current direction opposite to the first current direction, a repulsive force is generated, which lifts a piece of shielding structure, so that a dark area is generated in the corresponding light type area. The above is one design scheme of the adjustable shielding structure. The shielding structure can also be made of materials other than iron. The energized coil generates a magnetic force to push a mechanical arm, which pushes a piece of shielding structure. The shielding structure can also be embedded in a plastic part by insert injection molding. The specific implementation method is determined according to the actual space and situation. According to the number of pieces of the adjustable shielding structure, different pixel numbers of the system can be realized. It can also be designed as two layers of shielding structure according to the actual needs, as shown in the figure. The electromagnetic generated by the coil can be further optimized by increasing the shielding cover structure.
[0102] Further, the adjustable shielding structure needs to reach the target position after being lifted by the electromagnetic force, so through the support and the lining frame structure, some limiting structures are made on the top, so that the shielding structure is limited and fixed by the limiting structure after reaching the target specified position, that is, the shielding structure shields the light emitted by the optical system, and the limiting structure on the support limits the shielding structure to ensure that it can reach the specified position during the movement.
[0103] The structure of the utility model can carry a high-definition camera, capture the road conditions and the surrounding environment in real time, the image information obtained by the camera is processed by the computing unit of the vehicle, and the road, pedestrian, vehicle and other information are recognized, according to the processed data, the system sends control signals to the driving assembly, drives the shielding structure of the corresponding area, realizes pixel-level shielding of light, adjusts the illumination range and brightness of the headlamp, activates the shadow light type in the ADB headlamp, and ensures to provide the best lighting effect under different road conditions. It can also carry sensors, control units, actuators and the like, and can automatically adjust the light irradiation range and brightness according to the vehicle driving state, road conditions and weather conditions and other factors.
[0104] The utility model discloses a driving assembly drives the movement of shielding structure, and then realizes the switching of light unshielding and light shielding, can realize the light source pixel module of corresponding area's bright and dark, and then can realize ADB function well, avoids causing other vehicle drivers' daze problem, and improves the safety factor.
