Problems solved by technology

[0003] At present, most of the helmets with display function use the windshield of the helmet to reflect the projection beam to the eyes of the rider. However, this design will cause the windshield to avoid aberrations in addition to reducing wind resistance, so there are Difficulties in manufacturing increase product cost, and the special shape design of the windshield based on reducing wind resistance will also be limited, which will affect the stability of riding at high speeds
In addition, some helmets with display function embed the projection system in the upper cover of the helmet, which will reduce the thickness of the buffer layer in the upper cover and reduce its ability to protect the rider's head.
In addition, some helmets with display function directly project the projection beam from the bottom up to the eyes of the rider, so that the rider must move his sight down to actually watch the information displayed by the projection beam. will still pose a great threat to driving safety

Abstract

The invention discloses a head-mounted device. The head-mounted device includes a main body, a projection device and a beam combiner is provided. The main body has an upper shade portion and a lower shade portion, wherein the upper shade portion and the lower shade portion have an opening defined therebetween. The projection device is disposed within the lower shade portion and adapted to generate a projection beam, and the projection beam is adapted to be transmitted from the lower shade portion to the opening. The beam combiner is connected to the upper shade portion and located in the opening, wherein the beam combiner is located at a transmission path of the projection beam to be adapted to reflect the projection beam into the main body. The head-mounted device can save the manufacturing cost and can improve convenience and safety for usage.

Description

technical field [0001] The present invention relates to a wearable device, and in particular to a head-mounted device with a display device. Background technique [0002] Head-mounted displays (HMDs) are wearable devices that use an optical projection system to project images or text information into the eyes of users. In addition to being used in the military field, head-mounted displays are also used in industrial production, simulation training, stereoscopic display, medical treatment, sports, video games and other fields. The rise of heavy motorcycle sports in recent years has driven the combination of head-mounted displays and traditional helmets. In detail, when the heavy locomotive is running at high speed, if the rider turns his sight away from the road ahead in order to watch the instrument panel, it will cause a high degree of danger on the ride. Based on the above, the safety helmet with a display function can instantly project the information on the dashboard t...
