[0024] The present invention is further described in detail below in conjunction with embodiments, but the protection scope of the present invention is not limited thereto. Example 1

[0025] like Figure 1 , 2 As shown, the utility model relates to an MR head display device, which is an important component of an MR mixed reality device. The MR mixed reality device includes a VR device (virtual reality device) and an AR device (augmented reality device) in application. Here, the VR head display device is taken as an example. The device includes a shell 1, and an optical machine module 2 is provided in conjunction with the shell 1. The optical machine module 2 is detachably arranged in the shell 1 through the cooperation of a positioning component and a disassembly component.

[0026] In this embodiment, the assembled shell 1 and optical-mechanical module 2 constitute a complete MR head-mounted display device. During the implementation process, the optical-mechanical module 2 and the shell 1 are matched with a positioning component, that is, the optical-mechanical module 2 is detachable. After the assembly of the optical-mechanical module 2 and the shell 1 is completed, the two are locked to ensure the stability of the optical-mechanical module 2 during application and improve the user experience.

[0027] In this embodiment, the optical machine module 2 and the housing 1 are unlocked by disassembling the components.

[0028] In this embodiment, the positioning components are mirror-imaged in the spaces 3 on both sides of the housing 1 along the central axis of the device, and cooperate with the corresponding sides of the optical machine module 2 . Example 2

[0029] like Figure 3 , 4 As shown, on the basis of Example 1, the positioning assembly includes guide grooves 4 arranged on both sides of the optical machine module 2, guide strips 5 are arranged on both sides of the inner part of the shell 1 to cooperate with the guide grooves 4, and a locking assembly is provided to cooperate with any set of corresponding guide grooves 4 and guide strips 5.

[0030] The locking assembly includes a fixing member 6 provided on the side of the guiding bar 5 facing away from the guiding groove 4. A locking pin 7 is provided in cooperation with the fixing member 6. A first through hole 9 is provided on the guiding bar 5 in cooperation with the locking pin 7, and a clamping groove 10 is provided on the guiding groove 4 in cooperation with the first through hole 9. A first restoring member 8 is provided between the locking pin 7 facing away from the clamping groove 10 and the fixing member 6.

[0031] The other end of the locking pin 7 is provided with a first inclined surface 11 facing the bottom of the housing 1.

[0032] In this embodiment, the positioning assembly is integrally positioned and matched by the guiding grooves 4 on both sides of the optical engine module 2 and the guiding bars 5 on both sides inside the housing 1. In order to ensure the stability of the installation of the optical engine module 2, after the optical engine module 2 is installed in place, the locking assembly locks the optical engine module 2 and the housing 1. The disassembly assembly is also mainly arranged corresponding to the locking assembly.

[0033] Specifically, the fixing member 6 can be set as a U-shaped member or a similar structure to ensure that it can fix the locking pin 7. Here, the U-shaped member is taken as an example. The U-shaped member is installed in the space 3 on the side of the housing 1 for overall positioning. The U-shaped member is horizontally arranged, and its opening faces the guiding groove 4. The locking pin 7 is generally coaxial with the opening, or at least ensures that the locking pin 7 can always move left and right along the first through hole 9. One end of the locking pin 7 facing away from the opening of the U-shaped member is connected to the U-shaped member through the first restoring member 8. Here, the first restoring member 8 is generally set as a compression spring to ensure that the locking pin 7 can be smoothly pushed out along the first through hole 9 with the assistance of the first spring and abut against the clamping groove 10 in the guiding groove 4. Obviously, in the case of complete installation, the first through hole 9 and the clamping groove 10 are coaxial.

[0034] In this embodiment, in order to ensure that the locking pin 7 can slide smoothly along the guiding groove 4 during the installation process, the surface of the end of the locking pin 7 facing away from the first restoring member 8 and facing the bottom of the housing 1 is set as the first inclined surface 11 to avoid the optical engine module 2.

[0035] In this embodiment, the installation method of the optical engine module 2 is that when the guiding groove 4 of the optical engine module 2 is inserted into the housing 1 along the guiding bar 5, the locking pin 7 compresses the first spring outward under the interaction of the first inclined surface 11 and the guiding groove 4. When the optical engine module 2 is assembled in place, the locking pin 7 moves to the right to the clamping groove 10 under the reaction force of the first spring, realizing the fixation of the optical engine module 2. Embodiment 3

[0036] As Figure 5 shown, on the basis of Embodiment 2, a second through hole 12 is provided on the locking pin 7, and the disassembly assembly includes a button provided in cooperation with the second through hole 12. The button includes a contact section 13, a sliding section 14, and a pressing section 15 arranged in sequence from top to bottom.

[0037] The sliding section 14 includes a second inclined surface 16 disposed upwardly toward one side of the first restoring member 8 , a third inclined surface 17 is disposed at the second through hole 12 to match the second inclined surface 16 ; and a second restoring member 18 is disposed between the button and the fixing member 6 .

[0038] In the present embodiment, the disassembly component is realized by setting a second through hole 12 on the lock pin 7, so as to cooperate with the setting of a button. Obviously, the button is accessible to the user, and for the convenience of operation, its bottom is generally set at a accessible position at the bottom of the shell 1; for the convenience of handling, the button and the lock pin 7 are generally set vertically, and the button is sequentially set from top to bottom as a contact section 13, a sliding section 14 and a pressing section 15. The sliding section 14 is an important position of the button, and it slides with the second through hole 12 to control the unlocking in the locked state; in the present embodiment, the contact section 13 and the pressing section 15 are generally set to be cylindrical, and their bottom surface areas are different. The two are connected by the sliding section 14, and the upper bottom surface area of ​​the sliding section 14 is smaller than the lower bottom surface area.

[0039] Specifically, the sliding section 14 is configured as a table-type structure having a second inclined surface 16, wherein the second inclined surface 16 is configured upwardly toward one side of the first restoring member 8, and the second through hole 12 is also configured with a third inclined surface 17 corresponding to the second inclined surface 16, that is, when in the locked state, the upper part of the second inclined surface 16 is fitted with the lower part of the third inclined surface 17, and during the unlocking process, the second inclined surface 16 slides upward relative to the third inclined surface 17, the locking pin 7 moves to the left, and the first restoring member 8 is compressed.

[0040] In this embodiment, a second reset member 18 is disposed outside the contact section 13, whose outer diameter is smaller than the minimum outer diameter of the sliding section 14 and the upper end is fixed to the fixing member 6. The second reset member 18 is generally configured as a compression spring, which is used to reset the button that has been unlocked, improve the feel during the unlocking process, and prevent the button from over-extension.

[0041] In this embodiment, the optical machine module 2 is disassembled in that when the button is pressed, the button faces upward, the second inclined surface 16 slides relative to the third inclined surface 17, and the locking pin 7 moves outward, the locking pin 7 disengages from the slot 10, and the optical machine module 2 is removed. Example 4

[0042] On the basis of Example 3, a third through hole 19 and a fourth through hole 20 are respectively provided at the bottom of the housing 1 and the bottom of the fixing member 6 that cooperate with the button, and a limiting ring 21 is provided outside the pressing section 15 between the third through hole 19 and the fourth through hole 20.

[0043] In this embodiment, in order to ensure the use of the key, corresponding through holes 19, 20 are provided at the bottom of the shell 1 and the bottom of the fixing member 6 of the corresponding key, and a limiting ring 21 is provided outside the pressing section 15 between the third through hole 19 and the fourth through hole 20. Obviously, the outer diameter of the limiting ring 21 is larger than the inner diameter of the third through hole 19 and the fourth through hole 20, thereby ensuring the safety of the key use. Example 5

[0044] On the basis of the third embodiment, a contact switch 22 is provided above the contact section 13 , and a control unit is provided in cooperation with the contact switch 22 .

[0045] In this embodiment, in order to further ensure the safety during the disassembly of the optical machine module 2, a contact switch 22 is set in the space above the contact section 13. Generally speaking, when the user presses the left and right buttons at the same time, the tops of the contact sections 13 of the two buttons will contact the contact switch 22, closing the switch. After the control unit receives the electrical signal, it controls the circuit of the entire MR device to disconnect, and the user completes the operation of safely exiting the optical machine module 2.

[0046] In this embodiment, the control unit is set to be easily understood by those skilled in the art, and can be set by those skilled in the art according to actual needs. Here is an implementation method, that is, a control circuit is set, a switch circuit is connected in series in the optical machine module power circuit, and the host control circuit of the MR device detects the status of the two contact switches 22. The switch circuit is not limited to the specific implementation form and is controlled by the host control circuit. The host control circuit and the two contact switches follow the "AND gate" circuit logic. When and only when two buttons are pressed at the same time, the switch circuit is disconnected, and in other cases, the switch circuit is turned on, such as Figure 7 shown. Example 6

[0047] like Figure 6 As shown, on the basis of Embodiment 1, the housing 1 includes a main shell, and a front shell 23 is detachably provided on the front part of the main shell.

[0048] In this embodiment, the outer shell 1 can also be disassembled, and its front shell 23 can be disassembled and replaced based on needs to better match the optical machine module 2. Example 7
