[0042] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0044] Reference Figures 1 to 8 This application provides a head-mounted display device, which includes:

[0045] The device includes a head-mounted unit, a display body 1, and a connection unit 2. The display body 1 includes a housing 11 and a button 12. The housing 11 is provided with a pressing hole 111 and a plug-in hole 112. The button 12 passes through the pressing hole 111, and the pressing end of the button 12 protrudes from the housing 11 to facilitate the user's pressing operation of the button 12. The connection end of the button 12 is located inside the housing 11 to facilitate the connection between the display body 1 and the connection unit 2.

[0046] See Figures 1 to 3 One end of the connecting unit 2 is connected to the head-mounted unit (a conventional structure, not shown in the figure), and the other end of the connecting unit 2 is detachably connected to the connecting end of the button 12 through the insertion hole 112. For example, when the button 12 is not pressed, the other end of the connecting unit 2 is connected to the connecting end of the button 12, while when the button 12 is pressed, the other end of the connecting unit 2 can be separated from the connecting end of the button 12 to achieve the disassembly of the display body 1 and the connecting unit 2.

[0047] Specifically, the pressing hole 111 can be located in the middle of the upper surface of the housing 11, so that the button 12 is connected to the middle area of ​​the housing 11, so that the user can press the button 12.

[0048] In addition, the head-mounted display device provided in this application embodiment can be an XR device, which refers to imaging display devices such as AR (Augmented Reality), VR (Virtual Reality), or MR (Mixed Reality); and the connection unit 2 can connect the head-mounted unit and the display body 1 through wires, thereby realizing the display function of the display body 1.

[0049] This application embodiment provides a head-mounted display device including a head-mounted unit, a display body 1, and a connection unit 2. The display body 1 includes a housing 11 and a button 12. The housing 11 is provided with a pressing hole 111 and a plug-in hole 112. The button 12 passes through the pressing hole 111. One end of the connection unit 2 is connected to the head-mounted unit, and the other end of the connection unit 2 is detachably connected to the connection end of the button 12 through the plug-in hole 112. This allows the head-mounted unit to be disassembled and assembled with the display body 1 through the connection unit 2, achieving small-volume storage of the head-mounted display device and improving its portability.

[0050] Optionally, see Figures 3 to 5 The connecting end of the button 12 has a stop tooth 121, and the other end of the connecting unit 2 has a plurality of first positions 21. The button 12 has an unpressed state and a pressed state.

[0051] When the button 12 is not pressed, the stop tooth 121 engages with the first gear position 21.

[0052] When the button 12 is pressed, the stop tooth 121 disengages from the first stop 21, so that the display body 1 can move relative to the connecting unit 2.

[0053] Specifically, when the other end of the connecting unit 2 is detachably connected to the connecting end of the button 12 through the plug hole 112, if the head-mounted display device needs to display when worn, the connection between the display body 1 and the connecting unit 2 can be maintained. At this time, the button 12 can be in an unpressed state. By stopping the stop tooth 121 in the first position 21, a stable connection between the display body 1 and the connecting unit 2 can be ensured.

[0054] If the head-mounted display device needs to be stored or carried, in order to reduce the size of the head-mounted display device, the display body 1 and the connecting unit 2 can be disassembled. At this time, the button 12 can be in the pressed state, and the stop tooth 121 can be disengaged from the first position 21 to ensure that the head-mounted display device can be stored in a small size.

[0055] In addition, when the other end of the connecting unit 2 has multiple first gear positions 21, the stop teeth 121 can cooperate with the stops of different first gear positions 21 to realize the flexible adjustment of the distance between the display body 1 and the face when the head-mounted display device is worn, so as to achieve the adjustment function of eye relief.

[0056] Optionally, see Figure 3 The other end of the connecting unit 2 also has a plurality of second positions 22, and the pressing state includes a first pressing stage and a second pressing stage;

[0057] When the button 12 is in the first pressing stage, the stop tooth 121 disengages from the first position 21 and can move between multiple second positions 22;

[0058] When the button 12 is in the second pressing stage, the stop tooth 121 can disengage from the second position 22.

[0059] Specifically, when the button 12 is in the first pressed stage, the stop tooth 121 can disengage from one of the first positions 21 and move within a region between multiple second positions 22. When the stop tooth 121 moves to be opposite the desired first position 21, the pressure on the button 12 can be released, thus achieving a stop engagement between the stop tooth 121 and the first position 21. This allows the head-mounted display device to flexibly adjust the distance between the display subject 1 and the face for different users and for the same user in various situations, including wearing glasses and not wearing glasses, thereby achieving an eye relief function.

[0060] When button 12 is in the second pressing stage, for example, if button 12 is pressed further when it is in the first pressing stage, the stop tooth 121 can disengage from the middle area of ​​the plurality of second positions 22, thereby realizing the disassembly of the display body 1 and the connecting unit 2. After the display body 1 and the connecting unit 2 are disassembled, the display body 1 can be placed in the hollow position of the head-mounted unit to ensure the compact storage of the head-mounted display device.

[0061] This application employs different degrees of pressing operation on the same button 12, which can flexibly adjust the distance between the display body 1 and the face, and also enable the disassembly of the display body 1 and the connecting unit 2. While ensuring the wearing comfort of the head-mounted display device, it reduces the volume of the head-mounted display device when stored.

[0062] Optionally, when the button 12 is in the first pressing stage, the pressing end of the button 12 is flush with the limiting surface formed by the outer surface of the housing 11.

[0063] Specifically, see Figure 3 When the button 12 is not pressed, the pressing end of the button 12 protrudes from the housing 11. When the head-mounted display device is in the wearing state, if it is necessary to adjust the distance between the display body 1 and the face, the button 12 can be pressed to put the button 12 into the first pressing stage, for example, pressing the button 12 downwards a distance of... Figure 3 The distance H1 in the middle, at this time the stop tooth 121 can disengage from a first gear 21 and move in the area between multiple second gears 22. When the stop tooth 121 moves to be opposite to the first gear 21 to be adjusted, the press of the button 12 can be released. During the reset process, the button 12 can realize the stop tooth 121 and the first gear 21 stop engagement.

[0064] When the pressing end of the button 12 is flush with the limiting surface formed by the outer surface of the housing 11, the user's further pressing can be restricted by the limiting surface formed by the outer surface of the housing 11. For example, the user's pressing finger is stopped by the outer surface of the housing 11 to remind the user that the button 12 is in the first pressing stage, ensuring the consistency of the pressing stage of the button 12.

[0065] In addition, the pressing distance H1 of the button 12 can be in the range of 0.5-2mm. For example, when H1 is 1mm, the button 12 can be pressed down by 1mm to pull the display body 1 closer to or further away from the face, so as to realize the flexible adjustment of the distance between the display body 1 and the face.

[0066] Optionally, see Figure 3 The pressing hole 111 has a clearance area 1111 at one end near the outside of the housing 11. When the button 12 is in the second pressing stage, the pressing end of the button 12 extends into the clearance area 1111.

[0067] Specifically, see Figure 3 In one embodiment, when the button 12 is in an unpressed state, the pressing end of the button 12 protrudes from the housing 11. If it is necessary to detach the display body 1 and the connecting unit 2, the button 12 can be pressed to enter a second pressing stage, for example, pressing the button 12 downwards by a distance of... Figure 3 The distance between them is H1+H2, at which point the stop tooth 121 can disengage from the second gear position 22 to achieve the disassembly of the display body 1 and the connecting unit 2.

[0068] In another embodiment, if it is necessary to disassemble the display body 1 and the connecting unit 2 when the button 12 is in the first pressing stage, the button 12 can be pressed further to enter the second pressing stage, for example, the button 12 can be pressed down a distance of... Figure 3 When the distance H2 is reached, the stop tooth 121 can disengage from the second gear 22 to achieve the disassembly of the display body 1 and the connecting unit 2.

[0069] The clearance area 1111 formed at the end of the pressing hole 111 near the outside of the housing 11 facilitates the continued pressing of the button 12 from the first pressing stage to the second pressing stage. For example, the pressing part of the user's finger can extend into the clearance area 1111 to continue pressing the button 12, so that when the button 12 is in the second pressing stage, the pressing end of the button 12 can extend into the clearance area 1111.

[0070] Specifically, the avoidance area 1111 can be in the shape of an inverted cone, a semi-circle, or a square. The pressing distance H2 of the button 12 can be in the range of 0.5-2mm. For example, when H2 is 1mm, when the button 12 switches from the first pressing stage to the second pressing stage, it can be pressed down by only 1mm to achieve the disassembly between the display body 1 and the connecting unit 2.

[0071] Optionally, see Figure 3 The housing 11 is provided with an abutting spring 13 inside, and the connecting end of the button 12 abuts against the abutting spring 13.

[0072] Specifically, when the button 12 is in the first pressing stage, the stop tooth 121 can disengage from a first position 21 and move within the area between multiple second positions 22. When the stop tooth 121 moves to be opposite the target first position 21 to be adjusted, the pressure on the button 12 can be released. During the reset process, the stop tooth 121 can engage with the first position 21. To facilitate the reset of the button 12, the abutment spring 13 can continuously abut against the connection end of the button 12.

[0073] Specifically, when the button 12 is in the first pressing stage, the stop tooth 121 on the connecting end of the button 12 can squeeze the abutment spring 13 and cause the abutment spring 13 to deform. When the pressure on the button 12 is released, the elastic restoring force of the abutment spring 13 can be used to move the button 12 upward, thereby resetting the button 12 and ensuring the stability of the button 12 under frequent pressing. Moreover, the abutment spring 13 can also provide a pressing feel to the button 12, improving the user's experience of operating the button 12.

[0074] Optionally, see Figure 3 The connection unit 2 includes a connection cover 23, in which a conductive component 24 is provided. One end of the conductive component 24 is electrically connected to the head-mounted unit, and the other end of the conductive component 24 is electrically connected to the display body 1.

[0075] Specifically, the head-mounted unit can provide power to the display body 1. For example, a battery can be installed in the head-mounted unit, one end of the conductive component 24 is connected to the battery in the head-mounted unit, and the other end of the conductive component 24 is electrically connected to the display body 1. This can achieve the connection between the battery and the display body 1, so as to ensure the stable display of the display body 1 for a long time.

[0076] In one embodiment, see Figure 3The connecting cover 23 includes a connecting plate 231 and a decorative cover 232. When the connecting plate 231 and the decorative cover 232 are fastened together, the wires provided in the connecting cover 23 can be hidden.

[0077] Optionally, see Figure 3 The conductive component 24 includes a connecting wire 241 and a first conductive terminal 242. The connecting wire 241 is embedded in the connecting cover 23, and the first conductive terminal 242 is connected to one end of the connecting wire 241 and protrudes from the connecting cover 23.

[0078] The housing 11 is provided with a second conductive terminal 113. When the other end of the connecting unit 2 is connected to the connecting end of the button 12, the first conductive terminal 242 is in contact with the second conductive terminal 113.

[0079] Specifically, when the first conductive terminal 242 is connected to one end of the connecting line 241 and protrudes from the connecting cover 23, the first conductive terminal 242 can be fixed in the groove on the connecting cover 23 to ensure the stability of the connection between the first conductive terminal 242 and the connecting line 241; and when the first conductive terminal 242 protrudes from the connecting cover 23, it is convenient for the first conductive terminal 242 to contact the second conductive terminal 113, ensuring the connection between the head-mounted unit and the display body 1 through the connecting unit 2.

[0080] Optionally, see Figures 6 to 8 The first conductive terminal 242 is provided with a first connecting contact 2421 and a regional contact 2422. The first connecting contact 2421 is electrically connected to the connecting line 241, and the regional contact 2422 is located on the side of the first conductive terminal 242 close to the second conductive terminal 113.

[0081] The second conductive terminal 113 is provided with a second connecting contact 1131 and a spring contact 1132. The second connecting contact 1131 is connected to the internal circuit of the display body 1, and the spring contact 1132 faces the area contact 2422.

[0082] When the other end of the connecting unit 2 is connected to the connecting end of the button 12, the spring contact 1132 abuts against the area contact 2422.

[0083] Specifically, when the button 12 is not pressed, the spring contact 1132 and the area contact 2422 can abut against each other to ensure the connection between the head-mounted unit and the display body 1. When the button 12 is in the first pressed stage, the stop tooth 121 can move between multiple second positions 22, which causes the second conductive terminal 113 to move relative to the first conductive terminal 242. The setting of the area contact 2422 on the first conductive terminal 242 can increase the contact area of ​​the area contact 2422, so that the spring contact 1132 can maintain abutment against the area contact 2422 when moving, thereby improving the stability of the connection between the head-mounted unit and the display body 1.

[0084] Optionally, see Figure 4 The insertion hole 112 is provided with a slide rail 114, and the connecting cover 23 is configured to slide in cooperation with the slide rail 114.

[0085] Specifically, the other end of the connecting unit 2 is detachably connected to the connecting end of the button 12 through the insertion hole 112. That is, during the frequent connection and disassembly of the display body 1 and the connecting unit 2, the other end of the connecting unit 2 needs to frequently insert into or withdraw from the insertion hole 112. In order to facilitate the stability of the insertion and engagement of the connecting unit 2 and the insertion hole 112, a slide rail 114 can be provided in the insertion hole 112 to provide a clear insertion path for the connecting unit 2.

[0086] Additionally, see Figure 4 The slide rail 114 and the base plate can be fixed to the side plate in the housing 11 with screws to ensure the stability of the slide rail 114.

[0087] Optionally, see Figure 5 The button 12 is provided with a limit ring 122 along its axis, and the limit ring 122 stops on the inner side of the housing 11.

[0088] Specifically, during frequent pressing of the button 12, in order to prevent the button 12 from coming out of the pressing hole 111, a limiting ring 122 can be set to stop it inside the housing 11. Specifically, the outer diameter of the limiting ring 122 can be larger than the diameter of the pressing hole 111, so as to stop the button 12 inside the housing 11 and prevent the button 12 from popping out of the housing 11 when resetting.
