Specifically, the display control system can transmit the display data corresponding to the display information to the PCB board 2 through the cable, and the PCB board 2 can analyze, process and convert the display data, and transmit it to the image production optical machine 3, and the image production optical machine 3. The data from the PCB board 2 can be analyzed and processed and fitted into a display image corresponding to the display system. The image production light machine 3 may include a light regulator and a luminous display screen, the light regulator can amplify the displayed image, the luminous display screen is located at the end of the image emitting end 3a, and the display image can be imaged on the luminous display screen. The image transmitting end 3a can project the resolved image to the reflector 4 through light, and the reflector 4 can reflect the light to the display element 6, and after the display element 6 is reflected and refracted, a projection virtual image is formed in front of the driver 200, The driver 200 can see the projected virtual image through the display element 6 . The display element 6 can perform distortion correction on the display image, which can prevent the display image from being distorted, so that the display effect of the display element 6 can be improved. Moreover, the optical reflective sheet has a good light transmission effect, and the part of the optical reflective sheet other than the display image can be formed as a transparent member, thereby preventing the display member 6 from blocking the windshield of the vehicle, thereby improving driving safety.

Since the display member 6 is rotatably arranged on the support frame 5, the rotation angle between the display member 6 and the support frame 5 can be adjusted according to the actual use requirements, thereby adapting to different drivers 200 and different driving habits, and The display image can be adjusted to be directly in front of the driver 200, and the driver 200 can know the display information of the display control system through the display image without switching the line of sight when driving the vehicle, which not only brings great convenience to the actual operation of the driver 200 , can also improve the driving safety of the vehicle.

When the stature of the driver 200 is short, and the rotating display member 6 still cannot ensure that the displayed image is located directly in front of the driver 200, the support frame 5 can be pressed down, and the support frame 5 can drive the display member 6 to move down to a suitable position. Location. When the driver 200 is tall and the rotating display member 6 still cannot ensure that the displayed image is directly in front of the driver 200, the support frame 5 can be pulled upward, and the support frame 5 can drive the display member 6 to move upward to a proper position.

thus. Through the above arrangement, the vehicle head-up display system 100 can make the overall structure of the vehicle head-up display system 100 simpler and the operation more convenient by setting the image production optical machine 3, the reflector 4 and the display element 6. By arranging the display member 6 to be rotatably disposed on the support frame 5, the rotation angle between the display member 6 and the support frame 5 can be adjusted according to the actual use requirements, so that the display image can be positioned directly in front of the driver 200, and the driving The driver 200 can know the display information of the display control system through the displayed image without switching sight lines when driving the vehicle, which not only brings great convenience to the actual operation of the driver 200, but also improves the driving safety of the vehicle. By arranging the adjustment groove 52 on the support frame 5, the support frame 5 can move up and down relative to the box body 1 through the adjustment groove 52, so that the position of the display element 6 in the vertical direction can be easily adjusted, which can facilitate the actual operation of the driver 200. .
