Problems solved by technology

However, the field of view of the optical system is too small, which will affect the driver's immersion in observing images
Therefore, increasing the field of view of the optical system improves the user experience while ensuring the miniaturization of the structure and the high imaging quality of the optical system, which brings challenges to the design of the optical system of the head-up display device.

Abstract

A folded optical system for a head-up display device of a motorcycle helmet comprises a collimation light source, a miniature display, a lighting module, an imaging system, a planar semi-transparent semi-reflective mirror, a spherical semi-transparent semi-reflective mirror and an aperture diaphragm. An optical path is folded by the large-aperture spherical semi-transparent semi-reflective mirrorand the planar semi-transparent semi-reflective mirror, the visual field is expanded, the resolution of the optical system is improved, and the folded optical system has the characteristics of simplestructure, low processing cost, high brightness, low loss, high imaging quality and the like.

Description

technical field [0001] The invention relates to a motorcycle helmet, in particular to a folding optical system for a head-up display device of a motorcycle helmet. Background technique [0002] The motorcycle helmet is the driver's head protection device, which can reduce the driver's injury and even save the life when the motorcycle is driven by external shocks. With the development of technology and communication technology, traditional motorcycle helmets can no longer meet the needs of drivers. For example, drivers cannot answer voice messages in time, obtain speed information and real-time navigation information of the road ahead, so they are multi-functional. Sex helmets are getting more and more applications. [0003] Multifunctional helmets usually use a head-up display device (HUD) to image the information on the display screen into the driver's field of vision, and at the same time ensure that the driver's observation of the external real world scene is not blocked...
