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.

[0004] The shortcomings in the existing production of vehicle head-up display equipment are:

[0005] 1. The components of existing vehicle head-up display devices 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 connection has poor adjustability. The parameters of optical components are relatively strict and require multiple debugging and calibration. The existing production method is obviously not convenient for optical equipment manufacturing, and has poor production efficiency and low yield rate;
