Description

Technical Field

[0001] The utility model belongs to the technical field of head-up display, and specifically relates to a head-up display pre-starting device and a vehicle. Background Art

[0002] With the development of new energy vehicle technology, head-up display (HUD) functions are commonly equipped in existing vehicles, improving the driver's driving experience. In the existing technology, after getting in the vehicle, the user turns on the head-up display (HUD) function by switching on the switch on the central control screen.

[0003] The comparative document (CN220105421U) provides a head-up display device, which relates to the field of head-up display technology and includes a curved mirror assembly and a flip assembly. The curved mirror assembly is formed with sector teeth, and the flip assembly includes a worm arranged along the X direction. The sector teeth and the worm engage to cause the curved mirror assembly to flip along the X direction. The flip assembly also includes an elastic adjustment member arranged perpendicular to the X direction, and the elastic adjustment member and the worm have an interference fit. When the curved mirror flips, the elastic adjustment member will flip at a small angle along with the worm. The elastic adjustment member can be adjusted to abut against the worm through its elasticity, eliminating the X-direction gap between the worm and the curved mirror assembly. This avoids the problem of virtual image jitter and ghosting caused by the resonance of the curved mirror assembly due to the loose locking of the X-direction force when the amplitude of the vehicle body vibration is transmitted to the curved mirror assembly. The transmission system is simple, the size is small, and the layout is more advantageous.

[0004] Although the above-mentioned comparison document improves the clarity of the HUD display, it does not take into account the timing issue of HUD startup.

[0005] HUD usually includes a transmission system, an optical display system and a picture generation unit (PGU). After power-on, the startup time of the PGU and the optical display system is almost zero and can be ignored. However, the startup of the transmission system requires adjusting the angle of the aspherical mirror of the optical display system through the transmission to adjust the imaging height, so that the user can only see the image within a specific height range. At the same time, in the prior art, considering the risk of sunlight backflow, each time the user locks the car, the transmission system will drive the lens back to a safe position, that is, before each use, the transmission system will drive the lens from a safe position to a use position. There are two transmission methods in the industry, gear transmission and turbine worm gear transmission, but both methods require a waiting time of about 10 seconds. That is, after the user turns on the HUD function, due to the work of the transmission system, it is necessary to wait about 10 seconds to see the HUD image, which wastes time. Utility Model Content

[0006] The present invention aims to overcome the deficiencies of the prior art and proposes a head-up display pre-start device and a vehicle to achieve the following objectives: through the head-up display pre-start device of the present application, the user can see the image immediately after turning on the HUD without waiting, thereby improving the user experience and reducing the user's waiting time.

[0017] The following, with reference to the accompanying drawings, further illustrates the specific implementation methods of the present invention through the description of embodiments. The purpose is to help those skilled in the art gain a more complete, accurate, and in-depth understanding of the utility model's concept and technical solutions, and to facilitate their implementation. It should be noted that the "connection" mentioned in this application includes both electrical connections for power supply and distribution and signal transmission for information transmission. To further clarify the technical solutions of the present invention, the present invention is explained through the following embodiments.

[0018] In the existing technology, after the vehicle is powered on, the user activates the HUD display through the HUD function switch on the host central control screen, and then the HUD transmission system and image generation unit work in sequence. This usually takes about 10 seconds, wasting time and giving the user a bad experience.

[0019] In order to solve the above problems in the prior art, the present application proposes a head-up display pre-start device, such as Figure 1 As shown, the pre-start device includes a vehicle power-on detection device, a HUD transmission system, an optical display system, a HUD image generation unit, and a host, wherein the vehicle power-on detection device is connected to the HUD transmission system, and the host is respectively connected to the HUD transmission system and the HUD image generation unit; the HUD image generation unit is connected to the optical display system; the optical display system is provided on the HUD transmission system for adjusting the position of the optical display system.

[0020] Specifically, the vehicle power-on detection device is used to send a power-on success signal to the HUD transmission system after the vehicle is powered on; the HUD transmission system is used to pre-start after receiving the power-on success signal, control the optical display system to reach the image display position in advance, and send a pre-start completion signal to the host; the host is used to send a control signal to the HUD image generation unit after receiving the pre-start completion signal and the driver's head-up display start signal; the HUD image generation unit is used to generate an image after receiving the control signal and send it to the optical display system for display.

[0021] In this embodiment, the host may be an in-vehicle infotainment system equipped with a central control screen, which supports monitoring and control of various electronic units of the vehicle, can realize human-computer interaction, and improve user experience.

[0022] In this embodiment, the optical display system includes an optical lens, a controller and a projector. After the controller receives the image generated by the PGU, it projects it onto the lens through the projector. The lens then further projects the image onto the front windshield of the vehicle through optical principles. The specific display position is controlled by the transmission system.

[0023] In this embodiment, the HUD transmission system includes a driver identification device, a transmission controller, a transmission mechanism, and a memory. The transmission controller is respectively connected to the driver identification device, transmission mechanism, memory, vehicle power-on detection device, and host computer. In this embodiment, the transmission structure can adopt a gear transmission, a worm gear transmission, or a similar transmission mechanism. Accordingly, the lens of the optical display system is mounted on the transmission mechanism, and the lens' angle and position are controlled by the transmission mechanism.

The driver identification device may include a fingerprint verification device, a facial recognition camera, or the like. The memory is used to store image display positions set for different drivers. Upon receiving a power-on success signal from the vehicle power-on detection device, the transmission controller is used to retrieve the image display position set by the corresponding driver from the memory based on the corresponding driver's identity information and control the transmission mechanism to move the optical display system to the selected image display position.

[0024] The transmission system of the present application is provided with a driver identification device, which can match the corresponding preset HUD image display position according to different drivers, eliminating the need for users to repeatedly adjust it, thereby improving the user experience.

[0025] In actual use, the driver's vision can be obstructed in weather conditions such as heavy rain or snow.

The rain detection sensor is configured to control the host computer to shut down the HUD image generation unit when the rainfall exceeds a preset threshold. The preset threshold can be flexibly set based on the driver's actual situation.

[0027] After the vehicle is powered on, the user is usually adjusting the driving posture. During this period, the device of the present application is pre-started, which can save time. At the same time, after the user turns on the HUD function switch through the host, the image can be seen immediately without waiting, which can improve the user experience.
