Double-screen display platform for head-up display system

Abstract

The invention discloses a double-screen display platform for a head-up display system. The double-screen display platform comprises an upper screen display for AR (Augmented Reality) navigation and a lower screen display for displaying instrument information, and consists of a PCB (Printed Circuit Board) assembly structure, a system bottom cover, a light source structure, a split-screen light guide structure and a system dustproof surface cover, the split-screen light guide structure comprises an upper screen mirror assembly, a lower screen short mirror, a diffusion sheet assembly and an upper screen wide mirror which are arranged on the system bottom cover; the system bottom cover is designed to be flat, the system bottom cover comprises a lower end bottom plate and an inclined plate extending from the lower end bottom plate to the front upper side, the upper end of the inclined plate is an upper screen wide mirror installation position, a concave part is formed in the lower end of the inclined plate, and the concave part is a lower screen short mirror installation position. The double-screen display platform adopts a double-light machine and a split-screen structure, meanwhile, the plane mirror and the diffusion sheet are stable in installation and high in shock resistance, meanwhile, metal and liquid are reasonably adopted, heat dissipation and dust prevention are good, and therefore the head-up display system is clear and stable in display and high in comfort.

Description

technical field [0001] The invention relates to a vehicle-mounted head-up display device, in particular to a dual-screen display using a dual-optical machine and a split-screen structure, while the installation of a plane mirror and a diffuser is stable and strong in shock resistance, and at the same time rational use of metal and liquid has good heat dissipation and dust-proof performance. Dual-screen display platform with low signal transmission attenuation. Background technique [0002] With the development of the automobile industry, the technology of assisted driving is changing with each passing day, mainly the use of vehicle-mounted head-up display devices. The role of vehicle-mounted head-up display devices is to replace instruments, and to view various information that needs to be understood during car driving from the perspective of the driver. and modes are displayed, thereby facilitating driving and improving driving comfort at the same time. [0003] The defici...

AI Technical Summary

Problems solved by technology

[0004] 1. Most of the existing vehicle-mounted head-up display devices only have one display screen, and there are relatively many information for driving assistance, which makes the display content messy and poorly organized, affecting its comfort;

[0005] 2. There are many parts, large volume, and inconvenient to use;

[0006] 3. The plane mirror is easy to install, generally without anti-seismic treatment, the verticality of the plane and the stability of the bonding cannot be guaranteed, and the shock resistance is poor, and the lens is prone to tilt and rotate, resulting in deflection and failure of the optical path;

[0007] 4. The installation structure of the diffuser is simple, and only a simple fixing method is used, which cannot ensure the smoothness and wrinkling of the diffuser, and is easy to loosen and wrinkle, resulting in uneven beam diffusion angles, prone to dizziness, uneven brightness and other defects;

[0008] 5. The heat dissipation of the PCB component structure is unreasonable. Most of them adopt ventilation and heat dissipation methods, which can easily cause dust to enter the inside of the machine, causing the optical machine to crash and be damaged due to dust, and the lens will be blurred, affecting the visual effect;

[0009] 6. It is not necessary to carry out surface coating treatment on parts, such as bottom case, bracket, etc. The light beam is easy to produce diffuse reflection inside the device, which affects the transmission of the light beam signal
