Description

Technical Field

Background Art

[0002] The in-vehicle head-up display device is abbreviated as HUD, also known as the parallel display system. Due to its advanced assisted driving function, it is currently being vigorously promoted.

[0003] The vehicle-mounted head-up display device is mainly composed of a light source component, a light guide component, a free-form lens component, a car windshield, a human eye observation window, and a virtual image position. When imaging, the light from the light source passes through each component in turn, and finally forms an image through the accurate coordination of each component. Therefore, when the vehicle-mounted head-up display device is produced, the performance parameters of each component need to be tested, adjusted and calibrated multiple times.

[0004] At present, the various components of the vehicle-mounted head-up display equipment are generally processed and debugged separately, and then debugged together when assembled into a complete machine. Once a component does not meet the standards, it needs to be disassembled as a whole. At the same time, when assembled into a complete machine, most of the components are fixedly connected or the component connections have poor adjustability. The parameter requirements of optical components are relatively strict, and multiple debugging and correction are required. The existing production method is obviously not convenient for the manufacture of optical equipment, and has poor production efficiency and low yield rate. Summary of the invention
