It is understood that, referring to fig. 5 and 6, the optical assembly 22 includes a first lens group 221 and a second lens group 222, the first lens group 221 is located between the display unit 21 and the two lens groups; light emitted by the display unit 21 is transmitted to the second lens group 222 after passing through the first lens group 221, and the light emitted by the second lens group 222 is transmitted to the window 13. In this embodiment, the first lens group 221 is used for adjusting the emission direction of the light emitted from the display unit 21 to adjust the imaging aberration, and the second lens group 222 is used for changing the transmission direction of the light, so that the light can be finally transmitted to the window 13 and enter the human eye from the window 13.
Wherein, the second mirror group 222 includes a plane reflective lens 2221, a semi-transparent semi-reflective lens 2222 and a curved surface reflective lens 2223, and the emergent light from the first mirror group 221 passes through the plane reflective lens 2221 and is reflected to the semi-transparent semi-reflective lens 2222, the semi-transparent semi-reflective lens 2222 is right the emergent light from the plane reflective lens 2221 is reflected to the curved surface reflective lens 2223, the curved surface reflective lens 2223 is right the reflected light from the semi-transparent semi-reflective lens 2222 is reflected to the semi-transparent semi-reflective lens 2222, and the semi-transparent semi-reflective lens 2222 is right the emergent light from the curved surface reflective lens 2223 is projected to the window 13.

Specifically, the first position is a projection position between the light-transmitting portion 12 and the window 13, and light outside the housing 10 can be transmitted to the window 13 through the light-transmitting portion 12, so that the light shielding plate 60 is disposed between the light-transmitting portion 12 and the window 13 to shield light entering from the outside. The light shielding plate 60 is movably disposed in the mounting cavity 11, and when a user demands that the head-mounted device presents a virtual reality scene, the light shielding plate 60 can be driven to move to a light transmission path between the light transmission portion 12 and the window 13 to shield light entering from outside the housing 10, and only the light emitted from the display unit 21 enters human eyes through the optical assembly 22, so that the virtual reality scene is displayed. When the user demands the head-mounted device to present an augmented reality scene, and the camera 40 is not turned on, the light shielding plate 60 may be driven to move to the second position, so as to avoid the light transmission path between the light transmission portion 12 and the window 13, so that light outside the housing 10 enters the optical assembly 22, and enters the human eye after being emitted and converged from the display unit 21, thereby displaying the augmented reality scene.

And adopt camera 40 to acquire the environmental information outside casing 10, the visual angle that acquires based on camera 40 is bigger, and environmental information is handled through camera 40 after, the visual angle of the augmented reality scene that appears is bigger, and the effect that appears is better.
The head-mounted device in the embodiment of the invention is provided with at least two switching modes, for example, switching between an augmented reality scene and a virtual reality scene is realized by opening or closing the camera 40; for example, by driving the light shielding plate 60 to move to the first position, light transmission between the window 13 and the outside of the housing 10 is shielded, or driving the light shielding plate 60 to move to the second position, so that the environment information outside the housing 10 can be acquired from the window 13, and switching between the virtual reality scene and the augmented reality scene is realized. And the display effect that two kinds of switching modes reached is different, and the user can be based on a head-mounted device, can select the switching mode according to the demand of oneself, need not the user and changes head-mounted device, provides convenience for the user.
It will be appreciated that the camera 40 in this embodiment is also mounted on the mounting plate 80 on the side facing away from the viewing window 13.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
