This digital light is equivalent to the sensor detecting pedestrians, which can project zebra crossings on the ground to instruct pedestrians to cross the road safely, and can also project high-resolution signs on the road surface, such as stop warnings, guide signs, ice warnings and distance prompts. These technologies solve the problem of driving safety, but have not yet been implemented in more use scenarios of some vehicles. For example, the existing headlight system cannot play video data through the headlights. Summary of the invention

[0035] Figure 1 1 is a schematic structural diagram of a vehicle including a vehicle headlight system 100 with a projection and focusing function according to a specific embodiment of the present invention. As a specific embodiment of the present invention, the vehicle headlight system 100 with a projection and focusing function of this embodiment. In this embodiment, the headlight system 100 can be arranged at the headlight installation position in front of the vehicle. The headlight system can be placed on one side of the vehicle headlight placement position or on both sides. The headlight system 100 of this embodiment may include a housing 10 and a light matrix formed by a plurality of light source components 20 located at the housing 10. Each light source component 20 can emit light of any color. Among them, the headlight system 100 has a projection mode, and each light source component 20 of the light matrix is ​​controlled to emit different light at different times, so that when the headlight system is in the projection mode, the light emitted by the light matrix forms a video light, thereby enabling the headlight system 100 to play video images.

[0036] The vehicle headlight system 100 in this embodiment may include a shell 10 and a light matrix arranged at the shell 10, and the light matrix is ​​formed by a plurality of light source assemblies 20. Each light source assembly 20 can emit light of different colors so that the headlight system can play video images, and can realize the function of viewing images outdoors using vehicle headlights, thereby enriching the use scenarios of vehicle headlights and greatly improving the competitiveness of vehicles with this function.

[0037] In this embodiment, in order to be able to watch clear video image data, the number of light source components 20 in the light matrix of the headlight system may be as high as tens of thousands or even more, and the light matrix is ​​formed into a matrix of a pixel size as much as possible, so that the video image formed by the emitted light can be clear.

[0038] In this embodiment, a miniature light source assembly 20 may be used. The miniature light source assembly 20 may be a SMD LED lamp bead or other miniature light emitting bodies.

[0039] As a specific embodiment of the present invention, each light source assembly 20 of this embodiment includes at least three lighting elements 21, each lighting element 21 emits light of a different color, and the intensity of the light emitted by each lighting element 21 is adjustable, so that the light emitted by at least three lighting elements 21 can be combined to emit light of any color.

[0040] In this embodiment, each light source assembly 20 may include at least three lighting elements 21. Through the combination of at least three lighting elements 21, each light source assembly 20 can emit light of any color, so that the headlight system 100 can project different colors and patterns to meet the demand for changing colors during projection.

[0041] As a specific embodiment of the present invention, each light source assembly 20 of this embodiment may include three lighting elements 21, which respectively emit red, yellow and blue light. The intensity of the light emitted by each lighting element 21 is adjustable, and the light emitted by the three lighting elements 21 can be combined to emit light of any color.

[0042] Specifically, generally speaking, a variety of colors of light can be mixed by adjusting the brightness and intensity of red, yellow and blue lights. Therefore, as a preferred embodiment, in this embodiment, each light source assembly 20 only includes a combination of three lamp beads that can emit red, yellow and blue colors to achieve the requirement of this embodiment that each light source assembly 20 can emit light of any color.

[0043] Of course, in other embodiments, each light source assembly 20 may also be a combination of light elements 21 of other colors, as long as the light emitted by these light elements 21 can be combined into any color after adjusting the brightness and intensity.

[0044] Specifically, the number of the plurality of light source assemblies 20 of this embodiment may be tens of thousands or even more. The size of each light source assembly 20 and the distance between adjacent light source assemblies 20 may be such that the light source assembly 20 forms a similar pixel size, so that the light emitted by the plurality of light source assemblies 20 directly forms a projection image.

[0045] As a specific embodiment of the present invention, the headlight system 100 of this embodiment may further include a headlight lighting mode. The headlight system 100 is controlled to switch between the headlight lighting mode and the projection mode. When the headlight system 100 is in the headlight lighting mode, the headlight system 100 emits white light.

[0046] Specifically, the headlight system 100 of the present embodiment may include a headlight lighting mode and a projection mode, and may switch between the headlight lighting mode and the projection mode, so that while satisfying the headlight lighting, the headlight system 100 may also be used for projection, thereby increasing the function of the headlight system 100 of the present embodiment, satisfying the needs of users, and improving the user experience. Specifically, the headlight system 100 of the present embodiment may utilize the above-mentioned multiple light source assemblies 20 to emit white light when in the headlight lighting mode. Of course, as other embodiments, a white light source may also be separately provided in the headlight system 100, and when the headlight lighting mode and the projection mode of the headlight system 100 are switched mutually, the white light source is obtained by controlling the light source assembly 20 and the white light source to switch mutually.

[0047] As a specific embodiment of the present invention, the headlight system 100 of this embodiment may further include a control device 30 and a Bluetooth system 40. The control device 30 is connected to each light element 21, and is used to control the switch and light brightness of each light element 21, so as to control each light matrix to emit light of any color, and further control the headlight system 100 to emit lights or images of different colors. The Bluetooth system 40 is connected to the control device 30. When the Bluetooth system 40 receives a request signal from a terminal system connected to the Bluetooth system 40 requesting to play image data, the Bluetooth system 40 sends the image data matching the request signal to the control device 30, and processes the control device 30 to send a control signal to control the operation of the headlight system 100, so as to play the image data using the headlight system 100.

[0048] Specifically, generally, the start and stop of the light element 21 in the light source assembly 20 in the headlight system 100, and the intensity and brightness of the light irradiated by the light element 21 can be controlled by the control device 30. And the control scheme can be edited in advance, and the control is directly performed according to the control scheme during use, so that the headlight system 100 can project corresponding light, images or videos as required.

[0049] Generally speaking, some image data will be stored inside the vehicle, but most of the images that need to be projected can be obtained by connecting to an external system via the Bluetooth system 40, and then played out using the headlight system 100 through the control device 30, which increases the choice of image data for the headlight system 100 and improves the viewing experience.

[0050] Of course, in actual use, the headlight system 100 may also include a speaker 50, which is connected to the control device 30 and is used to synchronously play the sound in the image data when the headlight system 100 plays the image. The speaker 50 may be a voice speaker 50 inside the vehicle, or a separate speaker 50 set inside or outside the vehicle. The control device 30 may also control the surrounding playback mode of the speaker 50, thereby further improving the viewing experience.

[0051] As a specific embodiment of the present invention, the vehicle headlight system 100 of this embodiment may further include a stretching mechanism 60, which is connected to the housing 10, and the housing 10 is deformable. When the stretching mechanism 60 pulls the housing 10 to move, the housing 10 switches between the first state and the second state, thereby switching the headlight system 100 between the headlight lighting mode and the projection mode. The first state is the state when it is formed into a bowl shape, and the second state is the state when it is formed into a plane.

[0052] Specifically, in this embodiment, the housing 10 may be a flexible circuit board, which can provide a circuit for connecting to the outside world for the multiple light source assemblies 20 disposed at the housing 10. The flexible circuit board can be cut in blocks and woven into a mesh, so that the housing 10 can be switched between a bowl shape and a plane under the action of the stretching mechanism 60, thereby completing the switching between the headlight lighting mode and the projection mode.

[0053] Of course, the focusing focal length of the headlight can also be adjusted by deforming the housing 10 through the stretching structure.

[0054] As a specific embodiment of the present invention, the stretching mechanism 60 of this embodiment may include a motor 61 and a frame 62. The frame 62 is connected to the motor 61 and the housing 10. Driven by the motor 61, the frame 62 pushes the housing 10 to move so that the housing 10 switches between the first state and the second state. The motor 61 of this embodiment is connected to the control device 30, and the control device 30 controls the start and stop of the motor and the direction of movement, thereby ensuring accurate control of the movement of the stretching mechanism.

[0055] Specifically, the shape of the housing 10 can be adjusted through the movement of the motor 61 and the cooperation of the frame 62, so that the headlight system 100 can switch between the projection mode and the headlight lighting mode, which is convenient and quick. At the same time, the stretching mechanism 60 can also adjust the mode of the headlight system by controlling the bending degree angle of the housing 10, so as to meet the requirements of the headlight system for the focusing state of light.

[0056] As a specific embodiment of the present invention, the frame 62 of this embodiment is in the shape of an umbrella frame, and the frame 62 may include a fixed rod 621 and a plurality of telescopic rods 622. Among them, one end of the fixed rod 621 is fixedly connected to the motor 61, and the other end is rotatably connected to the middle of the shell 10, and the outer periphery of the fixed rod 621 is provided with an external thread. The plurality of telescopic rods 622 are arranged around the fixed rod 621, and each telescopic rod 622 may include a first end and a second end. The first ends of the plurality of telescopic rods 622 are interconnected to form a structure with a through hole, and the interior of the through hole is provided with an internal thread. The cooperation of the external thread and the internal thread enables the telescopic rod 622 to move along the axial direction of the fixed rod 621. The second ends of the plurality of telescopic rods 622 are connected to the shell 10. When the motor 61 drives the fixed rod 621 to rotate, the telescopic rod 622 drives the shell 10 to switch between the first state and the second state.

[0057] Specifically, in a specific embodiment, the frame 62 is formed as a fixed rod 621 located in the middle, and at least three telescopic rods 622 arranged around the fixed rod 621. The specific number of the telescopic rods 622 can be 3, 4, 5, 6 or 8, etc. Preferably, the number of the telescopic rods 622 in this embodiment is 6.

[0058] Specifically, the housing 10 of this embodiment is formed in a circular shape, and one end of the fixing rod 621 connected to the housing 10 is rotatably connected to the middle of the housing 10. Specifically, it can be rotatably connected to the housing 10 through a bearing. The other end of the fixing rod 621 can be driven to rotate by the motor 61.

[0059] In addition, the second end of each telescopic rod 622 is connected to the housing 10, and of course, the connection between each telescopic rod 622 and the housing 10 can be adjusted at an angle with the housing 10. This can be achieved specifically through a shaft hole structure. The first end of each telescopic rod 622 can be connected to a structure having a through hole, and the structure is also rotatably connected to the telescopic rod 622. An internal thread is provided on the inner wall of the through hole of the structure, and the internal thread of the structure and the external thread of the fixed rod 621 can cooperate. The motor 61 drives the fixed rod 621 to rotate and at the same time drives the second end of the telescopic rod 622 to reciprocate along the axis of the fixed rod 621, so that the housing 10 can switch between the first state and the second state.

[0060] As a specific embodiment of the present invention, the vehicle headlight system of this embodiment may further include an angle adjustment device connected to the headlight system 100. When the headlight system 100 is in the headlight lighting mode, the angle adjustment device can move in a controlled manner to adjust the angle of the headlight system 100, thereby changing the position and angle of the light emitted by the headlight system 100.

[0061] The angle adjustment device of this embodiment can adjust the angle of the headlight system 100, so as to adjust the angle of the external image or light projected by the headlight system 100, thereby improving the viewing experience or the direction of the headlight illumination and facilitating user use.

[0062] As a specific embodiment of the present invention, the angle adjustment device of this embodiment is linked to the turn signal switch of the vehicle, and the operation of the angle adjustment device is controlled by the turn signal switch, thereby adjusting the angle and position of the light of the headlight system.

[0063] Specifically, the headlight system 100 of this embodiment may include a voice control system 70, which can receive external voices and control the headlight system 100 after recognizing the voices. Specifically, the voice control system 70 can recognize the voices for controlling the start and stop of the headlight system 100, can recognize the voices for controlling the headlight system 100 to enter a projection mode or switch a headlight lighting mode, and can recognize the voices for controlling the start and stop and movement of the stretching mechanism 60.

[0064] As a specific embodiment of the present invention, this embodiment also provides a vehicle, which includes a vehicle headlight system 100 with a projection and focusing function.
