Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted displays, and particularly relates to a HUD display device which is convenient for processing. Background Art

[0002] With the development of intelligent vehicles, HUDs have begun to be applied in the automotive field. A head-up display (abbreviated as HUD) is a driving assistance system that can display important vehicle parameters such as road conditions, vehicle speed, engine speed, navigation, weather, etc. within the driver's line of sight without affecting the driver's view of the road ahead, thereby improving driving safety.

[0003] An HUD generally includes a light source, an optical channel, and a display component. To ensure the tightness of the optical channel, the optical channel is a through slot that penetrates up and down and is sealed on the side surface and is arranged on a reflecting seat. Since this through slot needs to perform light reflection, a reflecting surface is coated on the side wall of the through slot by means of vacuum coating. Since the four side walls of the through slot are in a closed state, during the processing of the reflecting surface, it is easy to have uneven processing of the reflecting surface, resulting in poor display effects.

[0030] Preferably, the first clamping buckle and the first bolt through-hole are located on the upper and lower sides of the first positioning post. When installing the first reflector and the second reflector, first insert the first mounting post into the first mounting hole, then buckle the first clamping buckle on the first clamping protrusion to achieve preliminary fixation of the first reflector and the second reflector. Finally, pass a bolt through the first bolt through-hole and tighten it in the first threaded blind hole to fix the first reflector and the second reflector. To ensure the sealing of the first reflector and the second reflector, the second mounting lug is bent towards the first reflector and provided on the second reflector, and the corresponding first mounting lug is provided in the middle of the side surface of the first reflector.

[0031] The diffusion component C includes a lens 4 and a first diffusion sheet 5. The first diffusion sheet 5 is used to diffuse the light of the light source, and the lens 4 is used to filter the diffused light. An installation groove b for installing the diffusion component C is provided at the upper end of the reflector seat A, and the outside of the installation groove b is located outside the upper end of the light channel a. The lens 4 and the first diffusion sheet 5 are stacked up and down in the installation groove b.

[0032] The display component B includes a mounting bracket 6 installed on the reflector seat A through a second mounting structure.

[0037] The display assembly further includes a secondary curved mirror (not shown in the figure) provided between the windshield and the display screen. During operation, the content on the display screen is transmitted onto the windshield through the secondary curved mirror. Due to the presence of the enhanced HUD display, the field of view angle will be increased. The increase in the field of view angle will cause the virtual image display screen to increase, which can enhance the fusion of reality and virtual effects. However, when the display screen image is fixed, when the virtual image display screen increases, the corresponding optical magnification will become larger, and the light spot will be more concentrated when sunlight backflows, resulting in a sharp rise in the temperature of the display screen. In severe cases, obvious burning phenomena will occur at this place and the screen will be burned out.

[0038] Therefore, in the present application, a temperature measuring component D for measuring the temperature of the display screen 7 is provided on the display component B. The temperature measuring component D includes a flexible circuit board 10 disposed between the display screen 7 and the upper cover 8.

A fixing pad 12 for fixing the flexible circuit board 10 is disposed between the flexible circuit board 10 and the upper cover 8. Meanwhile, a notch 8d for installing the flexible circuit board 10 is provided on the upper cover 8. Preferably, the fixing pad is made of heat-resistant foam, and two or more flexible circuit boards 10 are spaced apart.

[0039] Meanwhile, the temperature measuring component further includes a photosensitive sensor disposed on the secondary curved mirror for detecting the light intensity on the secondary curved mirror. Through the combined action of the photosensitive sensor and the temperature sensor, the temperature of the display screen is ensured to be within a suitable range.
