Referring to fig. 1 to 8 in combination, a head-mounted display device 100 is provided, and in an embodiment of the present application, the head-mounted display device 100 includes a mounting carrier 10 and a lens module 30. Wherein, the mounting carrier 10 comprises a mounting shell 13 and a movable bracket 15, the mounting shell 13 is provided with a mounting cavity 131 and an exposure port 132 communicated with the mounting cavity 131; the number of the movable brackets 15 is two, and the two movable brackets 15 are arranged side by side in the mounting cavity 131 and can be mutually close to and far away from each other. The number of the lens modules 30 is two, and each lens module 30 is detachably arranged on one movable bracket 15.
The mounting carrier 10 may be used to provide mounting locations for mounting the lens module 30 and other components of the head mounted display device 100, etc., so as to facilitate that the components of the head mounted display device 100 may be assembled to form a single unit for use. While the mounting carrier 10 is provided to include the mounting housing 13 and the movable bracket 15 provided in the mounting housing 13, on the one hand, it is made possible to split the mounting carrier 10 into the mounting housing 13 and the movable bracket 15 for separate and independent manufacture. At this time, the structure of the split mounting case 13 and movable bracket 15 is simpler than that of the mounting carrier 10, thereby facilitating improvement of the convenience of processing and molding of the mounting carrier 10. On the other hand, the two lens modules 30 are provided with mounting positions by the two movable brackets 15 which can be mutually close to and far away from each other, so that the distance between the two lens modules 30 can be adjusted, and users with different interpupillary distances can be adapted. The mounting housing 13 may be a waist-shaped housing structure, or may be a housing structure of other shapes, and the specific shape of the mounting housing 13 is not limited in this application. While the movable support 15 may have a circular structure so as to be adapted to the shape of the lens module 30 to give a good mounting position. Of course, the movable support 15 may have a square shape or other shape, and the specific shape of the movable support 15 is not limited in the present application. In addition, the movable bracket 15 may be manually driven by a user, for example: the two movable brackets 15 are brought closer to and farther away from each other by turning the knob 711 as described below. Naturally, the driving mode of the two movable brackets 15 approaching to and separating from each other may be automatically driven by a combination of a motor and a screw rod or a combination of a motor, a gear, a rack and the like.
The lens module 30 may be used for reflecting, refracting, etc. light emitted by the display screen in the head-mounted display device 100, so as to image the picture displayed by the display screen onto the retina of the user more clearly. Since the imaging principle of the lens module 30 is the prior art, the specific structure of the lens module 30 will not be described in detail herein. In addition, the number of lens modules 30 may be two to be used corresponding to the left and right eyes of the user, respectively. The detachable connection mode between the lens module 30 and the movable bracket 15 may be a clamping connection as described below, or may be a magnetic connection or a screw connection, which is not limited in the detachable connection mode of the lens module 30, so that the lens module 30 can be detached after being mounted on the movable bracket 15.
When the head-mounted display device 100 of the technical scheme of the application is used, since each lens module 30 in the head-mounted display device 100 is detachably arranged on the movable support 15 in the mounting carrier 10, a user can mount the corresponding lens module 30 on the mounting carrier 10 of the head-mounted display device 100 according to respective requirements for use. That is, the structural arrangement of the head-mounted display device 100 in this solution can realize the disassembly and replacement of the lens modules 30, so as to achieve that one head-mounted display device 100 can be used with a plurality of lens modules 30. At this time, compared with the related art in which one head-mounted display device 100 can only be used by being paired with one lens module 30, the head-mounted display device 100 in this embodiment can display images by installing different types of lens modules 30, so that the image quality of the images that can be displayed by the head-mounted display device 100 can be diversified and adapted to the respective needs of the user, thereby being beneficial to improving the user experience of the user on the head-mounted display device 100. In addition, the lens module 30 is detachable, so that when the part is damaged, the part can be directly taken down for replacement without replacing the whole head-mounted display device 100, thereby being beneficial to reducing the replacement cost and further improving the use experience of a user on the head-mounted display device 100. The two lens modules 30 are detachably mounted on the two movable brackets 15, so that the two lens modules 30 can be detached independently without interference. When one of the two lens modules 30 needs to be replaced, only the lens module 30 needs to be removed, so that the flexibility of removing the two lens modules 30 is improved, and the use experience of the user on the head-mounted display device 100 is further improved. In addition, the two movable brackets 15 can also move close to and away from each other in the installation cavity. This allows the spacing between the two lens modules 30 to be adjusted to accommodate users with different interpupillaries, thereby further improving the user experience of the head mounted display device 100. Therefore, the head-mounted display device 100 in this scheme is configured such that the two lens modules 30 are detachably mounted on the movable support 15, and the two movable supports 15 are set to be close to and far away from each other, so that each lens module 30 in the head-mounted display device 100 can be flexibly detached and replaced, the distance between the lens modules 30 is adjustable, and the use experience of the user on the head-mounted display device 100 is greatly improved.
Referring to fig. 7 and 8 in combination, in an embodiment of the present application, the lens module 30 and the movable frame 15 are connected by a clamping connection.

In this embodiment, both the movable bracket 15 and the lens module 30 are clamped by adopting the combination of the push-button buckle switch 11 and the buckle 31, so that after one of the buckles 31 and the other buckle switch 11 are initially pressed in a butt joint manner, the buckle 31 can be clamped with the push-button buckle switch 11, thereby realizing the installation of the lens module 30 on the movable bracket 15. When one of the buckles 31 is pressed again, the buckle 31 can be made to pop out from the push buckle switch 11, so that the lens module 30 is unlocked and detached. Therefore, the mounting process and the dismounting process of the lens module 30 are only needed to be simple, so that the convenience of dismounting the lens module 30 is further improved. Since the specific structure of the push-button switch 11 is conventional, the specific structure of the push-button switch 11 will not be described in detail herein.
