When the head-mounted display device is transmissive, the light-transmitting portion 100T of the second shielding body 100 is placed in a portion of the housing 1 that is transparent to the material, and the light-shielding portion 100B may be partially or completely wound up on the second housing shaft 110. The switching between the two causes the light-shielding portion 100B and the light-transmitting portion 100T to move by the rotation of the second housing shaft 110.

Optionally, the head mounted display device further includes a first adjusting mechanism 120. The first adjusting mechanism 120 is coupled to the second receiving shaft 110, and the second receiving shaft 110 is rotated by the first adjusting mechanism 120.

Optionally, the head mounted display device further includes a second adjusting mechanism 130. The second adjusting mechanism 130 is coupled to the first receiving shaft 20, and the second adjusting mechanism 130 drives the first receiving shaft 20 to rotate.

For example, as shown in FIG. 12, in order to facilitate the user to control the rotation of the first storage shaft 20 and the first storage shaft 110, the head mounted display device of the present invention further includes a first adjustment mechanism 120 and a second adjustment mechanism 130, The first adjustment mechanism 120 can control the rotation of the second storage shaft 110. For example, the first adjustment mechanism 120 rotates clockwise, and the second shielding body 100 is received in the second storage shaft 110, and the first adjustment mechanism 120 rotates counterclockwise. The second shielding mechanism 100 is deployed, and the second adjusting mechanism 130 can control the rotation of the first receiving shaft 20, for example, the second adjusting mechanism 130 rotates clockwise, and the flexible display screen 10 is received in the first receiving shaft 20, and the second adjusting mechanism 130 is reversed. When the hour hand rotates, the flexible display screen 10 is unfolded.

Optionally, the housing 1 includes a detachable first shielding body 90, and the first shielding 90 body is detached or mounted to enable the housing 1 to switch the first light transmittance and the second light transmittance.

For example, as shown in FIG. 12, when the detachable first shielding body 90 is detached from the casing 1, the light transmittance of the casing 1 is the second light transmittance, when the first shielding body 90 is mounted on the casing. The light transmittance of the housing 1 is the first light transmittance when the body 1 is used. It can be understood that the first shielding body 90 shown in FIG. 12 is only a schematic diagram of the embodiment of the present invention, and is not limited to the drawings. The specific structure location and size.

Optionally, the head mounted display device provided by the present invention further includes a protective lens disposed on the display window 40. The protective lens can prevent external dust and the like from entering the casing 1, affecting the optical component and its rendering effect.

It can be seen that, in the head-mounted display device of the present invention, when the housing 1 switches the first light transmittance, the light emitted from the display region 11 of the flexible display screen 10 is projected through the display lens through the optical lens 30 to Providing a display content of the user immersively viewing the display screen. When the housing 1 switches the second light transmittance, the first storage shaft 20 drives the flexible display screen to rotate, so that the light transmission area 12 of the flexible display screen 10 is corresponding to the display window 40. The outside light projects through the display window 40 through the light transmitting region 12, To provide users with a transparent view of the outside world.

Optionally, as shown in FIG. 13-14, when the display area 11 of the flexible display screen 10 is larger than the area A that can be projected by the optical lens 30, the area A is an image area that can be viewed by an actual user. . Therefore, the viewing angle of the content that can be displayed by the actual display area 11 can be much larger than the viewing angle of the user. When the user wants to move to other viewing angles for viewing according to the display content viewed by the current imaging area, the first storage axis 20 can be rotated. The flexible display screen 10 displays the movement of the area 11 so as to correspond to the target display area A corresponding to the viewing angle to be viewed. Therefore, the effect of VR perspective transfer can be realized, and the image content that should be displayed on the display screen is not required to be calculated by complicated image data, thereby solving the problem that the existing VR technology has a delay in viewing angle switching due to insufficient computing power. As an embodiment, the head mounted display device further includes a sensing device 140, such as an acceleration/geomagnetic sensing device or the like, and a controller 150. The sensing device 140 is configured to sense the motion orientation of the user's head. After the sensing device 140 senses the motion orientation of the user's head (eg, the angle of rotation, the displacement), the sensing device 140 transmits the motion orientation to the controller 150, and the controller 150 determines the corresponding target display region according to the motion orientation. The target rotation direction of the first storage shaft 20 and the target rotation amount of the first storage shaft 20, the controller 150 controls the first storage shaft 20 to rotate according to the target rotation direction and the target rotation amount so that the target display area corresponds to the optical lens 30. The setting finally allows the user to view the display content of the target display area through the display window 40. For example, it can be seen that the imaging area of the display area 11 corresponding to the optical lens is changed by the rotation of the first housing shaft 20, thereby realizing that the VR can see the virtual picture of the relative orientation according to the user turning the head. In the prior art, when the user turns the head, the display data of the corresponding orientation needs to be obtained through calculation, and the problem of the viewing angle switching delay due to the insufficient computing power is insufficient. In other embodiments, the rotation of the first housing shaft 20 can be controlled by a mechanical structure to achieve a viewing angle switching, such as the manner of the second adjustment mechanism 130 described above. It is also possible to implement an input operation by an input unit of the head mounted display device, and the controller 150 performs a corresponding view switching according to an input signal of the input unit. The input signal (including the coordinates, displacement, path, etc. of the input signal) has a preset correspondence with the switching of the angle of view. For example, the controller 150 determines a corresponding target display area according to the input signal, and the controller 150 controls the first storage shaft 20 according to the target rotation direction of the first storage shaft 20 and the target rotation amount of the first storage shaft 20 from the target display area. The rotation is performed in accordance with the target rotation direction and the target rotation amount so that the target display region is set corresponding to the optical lens 30. It can be understood that the sensing device 140 includes an input unit having a sensing function, for example, the touch signal can be sensed for the touch panel according to the preset. The touch signal acquires a corresponding target display area, a target rotation direction, and/or a target rotation amount. It can also be an infrared sensing device, which can acquire a user gesture, an iris detecting device, obtain a user's gaze orientation, and the like. That is, the solution can be combined with any input mode of the head mounted display device to obtain the target display area.

In other modes, the flexible display screen 10 may also be a display content including a plurality of display areas A, and each display area A corresponds to a different viewing angle. According to the acquisition target display area, the corresponding target rotation direction and the target rotation amount are obtained, and the target display area corresponding optical lens 30 becomes the imaging area for the user to view.
