The distance sensor 39 is electrically connected to the electronic assembly 40 to allow the electronic assembly 40 to control the operation of the display based on the detection data of the distance sensor 39. When the user does not wear the head-mounted display device 100, the distance sensor 39 does not detect any object within a corresponding distance, and at this time, the control center of the head-mounted display device 100 may consider that the head-mounted display device 100 is not worn by the user, and control the screen of the display to be in a screen-off or closed state; when the user wears the head mounted display device 100 and the forehead is attached to the third protector 38, the distance sensor 39 detects that there is an object, and the control center of the head mounted display device 100 determines that the head mounted display device 100 is worn by the user and controls the screen of the display to be lit.

Referring to fig. 6 and 7, when the electronic component 40 is connected to the frame 32, it is connected to the mating contact 341, and the display surface 42 of the electronic component 40 is away from the first portion 12 and faces the optical component 50.

As an embodiment, the head-mounted display device 100 may further include a heat dissipation assembly 60, where the heat dissipation assembly 60 is disposed on a side of the electronic assembly 40 facing away from the display surface 42 thereof, that is, the heat dissipation assembly 60 is disposed on a side of the electronic assembly 40 facing away from the optical assembly 50. The heat dissipation assembly 60 is a heat dissipation structure integrated with the electronic assembly 40, and may be any one or combination of heat sinks, heat dissipation holes, or heat dissipation fans, for example, to dissipate heat from the electronic assembly 40 and make the structure of the head-mounted display device 100 more compact.

Referring to fig. 7 and 8, the optical assembly 50 is detachably connected to the bracket assembly 30 and disposed opposite to the display surface 42 of the electronic assembly 40. In the present embodiment, the optical assembly 50 includes a connecting frame 52 and an optical lens 54 connected to the connecting frame 52. The attachment frame 52 is detachably attached to the frame 32, wherein the attachment frame 52 may be attached to the frame 32 by magnetic force. For example, the optical assembly 50 may include a third magnetic element 56 (fig. 7), and the third magnetic element 56 is disposed on the connecting frame 52 and is configured to be attracted to the frame 32. At this time, the frame 32 may be made of a magnetically conductive material (e.g., iron, etc.). Or, a fourth magnetic attraction element 39 (fig. 7) may be disposed in the frame 32, and the third magnetic attraction element 53 and the fourth magnetic attraction element 39 attract each other by magnetic force, so as to realize a convenient detachable mounting structure of the optical assembly 50. Similar to the holding structure of the first magnetic member 147 and the second magnetic member 28, in some embodiments, the third magnetic member 53 and the fourth magnetic member 39 can be made of a magnetic material or a magnetically conductive material, and are not limited to magnets, magnetic steel, etc. The specific materials and structures of the third magnetic element and the fourth magnetic element are not limited, and the third magnetic element 53 and the fourth magnetic element 39 can be attracted by magnetic force, which is not described in detail herein.

In one embodiment, the magnetic force acting direction between the third magnetic element 53 and the fourth magnetic element 39 can be substantially perpendicular to the plane of the frame 32, that is, the magnetic force acting direction between the third magnetic element 53 and the fourth magnetic element 39 is substantially perpendicular to the extending direction of the frame 32. At this time, when the head-mounted display device 100 is worn by a user, the plane of the frame 32 is substantially a horizontal plane, and the magnetic force acting direction between the third magnetic attraction piece 53 and the fourth magnetic attraction piece 39 is substantially along the vertical direction, so that the user can apply force along the vertical direction more easily when disassembling and assembling the optical assembly 50.

Further, in order to limit the direction of the magnetic force acting between the third magnetic element 53 and the fourth magnetic element 39, the connecting frame 52 may include a connecting surface 521 facing the frame 52, and the connecting frame 52 is stacked on a side surface of the frame 32 through the connecting surface 521, and the connecting surface 52 is substantially parallel to the plane of the frame 32. In this case, it can be considered that the connection surface 52 is substantially parallel to the plane of the frame 32, so as to ensure that the magnetic force acting direction between the third magnetic attraction piece 53 and the fourth magnetic attraction piece 39 is substantially along the vertical direction. Further, the third magnetic element 53 and the fourth magnetic element 39 can be disposed along the plane of the connecting surface 521.

The optical lens 54 is disposed on a side of the connecting frame 52 facing away from the frame 32. In this embodiment, the optical lens 54 is a transparent or reflective lens (e.g., a half-transparent and half-reflective lens), so that when the optical lens 54 reflects the multimedia content played by the electronic component 40, the user can also observe the real scene in front through the lens optical sheet 54, thereby implementing the visual experience of superimposing the virtual content on the real scene. The optical lens 54 has a reflective surface 541 facing the electronic component 40.

As an embodiment, the head-mounted display device 100 may further include a vision module 70, the vision module 70 may be disposed on the bracket assembly 30, and the vision module 70 is used for implementing a machine vision function or/and a shooting function of the head-mounted display device 100. Further, the vision module 70 is disposed on a side of the frame 32 facing away from the first portion 12. The vision module 70 includes a vision positioning unit and an image capturing unit. The vision positioning unit can be a binocular camera module and is used for tracking and positioning a target object. The image acquisition unit can be any one or combination of multiple RBG cameras and infrared cameras and is used for acquiring environment images.

Since the electronic assembly 30 is electrically connected to the plug-in mating contacts 341 of the cradle assembly 30, the battery assembly 20 can be electrically connected to the electronic assembly 40 and power the electronic assembly 40 sequentially through the contacts 1455, the contact pins 26, the wires, the plug contacts 127, and the mating contacts 341.

In some embodiments, referring to fig. 3 again, the head-mounted display device 100 may further include a connection line 80, and two ends of the connection line 80 are electrically connected to the plug contact 127 of the first portion 12 and the contact 1455 of the second portion 14, respectively, so as to electrically connect the battery element 20 and the electronic element 20. Further, the first part 12 may be provided with a first insertion hole 120, and the second part 14 may be provided with a second insertion hole 140, so that both ends of the connection line 80 are respectively inserted into the first insertion hole 120 and the second insertion hole 140. Further, the first inserting hole 120 may be disposed in the first housing 121 and electrically connected with the inserting contact 127. The second insertion hole 140 can be disposed in the second housing 141 and electrically connected to the contact 1455, and when two ends of the connection line 80 are respectively inserted into the first insertion hole 120 and the second insertion hole 140, the battery assembly 20 can be electrically connected to the electronic assembly 40 through the connection line 80.

Further, in order to hold the connection line 80, the wearing assembly 10 may also be provided with a holder 19. The retainer 19 may be one or more, and the retainer 19 may be disposed on any one or more of the first portion 12, the second portion 14, and the adjustment portion 16. In the present embodiment, the holder 19 is an annular structure 190 disposed on the adjusting portion 16, and the connecting wire 180 is disposed through the annular structure 190, so that the annular structure can display the extending path of the connecting wire 80.
