[0028] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will make these embodiments readily achievable by those skilled in the art. However, the present invention can also be implemented in various different forms, and therefore is not limited to the embodiments described below. In addition, for the sake of clearer description of the present invention, components not connected to the present invention will be omitted from the drawings.

[0029] like Figure 1As shown, a mixed reality glasses that prevents the wearer from falling off consists of glasses 1 and control unit 2. Glasses 1 is a mixed reality (MR) device with multiple sets of sensors inside, which can recognize the wearer's movement and voice. Glasses 1 and control unit 2 are connected to upper strap 11 via side straps 12 on both sides. The side straps 12 are provided with elastic bands 13 inside, which are used to adjust the length of the side straps 12.

[0030] like Figure 2 The control component 2 has an upper strap groove 22 on one side above it for connecting to the glasses 1 via the upper strap 11; the control component 2 has side strap grooves 21 on both sides, and an elastic band 13 is provided inside the side strap 12, with one end of the elastic band 13 inside the side strap groove 21.

[0031] A limiting member 3 is provided on one side of the control member 2, a closing button 31 is provided above the limiting member 3, and an annular connecting block 32 is provided on one side of the limiting member 3.

[0032] The control component 2 is provided with a control wheel 4 in the middle, and the control wheel 4 is provided with protrusions around its perimeter to facilitate hand-held rotation by the operator.

[0033] like Figure 3 , Figure 4 , Figure 5 As shown, the control wheel 4 has an annular groove-shaped connecting groove 41 inside, which facilitates cooperation with the connecting block 32 on the limiting member 3. The connecting groove 41 has an annular limiting groove 411 inside. A rod-shaped control rod 43 is provided on one side of the control wheel 4. The control rod 43 is provided with a ratchet 42, a control protrusion 44, and a fixing protrusion 45. The control protrusion 44 is arranged in a "cross" shape. The fixing protrusion 45 is located at one end of the control rod 43 and is arranged in a "cross" shape.

[0034] The connecting block 32 of the limiting member 3 is provided with a connecting block 33 inside. The connecting block 33 is connected to the telescopic shaft 34. The limiting member 3 is provided with a driving device that can drive the telescopic shaft 34 to perform telescopic movement, thereby driving the connecting block 33 to perform telescopic movement. When the connecting block 32 is inside the connecting groove 41, the telescopic shaft 34 drives the connecting block 33 to extend into the limiting groove 411, which can limit the control wheel 4.

[0035] The control component 2 is equipped with a damping wheel 6 inside. The damping wheel 6 is annular, and the inner ring is provided with damping protrusions 61 connected by elastic rods 62. When the ratchet 42 rotates inside the damping wheel 6, it will be damped by the damping protrusions 61. The damping wheel 6 is not limited to the style shown in the figure. Any annular structure that can dampen the rotation of the ratchet 42 can be used.

[0036] The damping wheel 6 has a receiving cavity 7 on one side. The receiving cavity 7 has a ring structure, and the ratchet 42 can move into the receiving cavity 7.

[0037] The control component 2 is equipped with a gear 8 inside. The gear 8 is connected to the control protrusion 44 of the control lever 43. When the control lever 43 rotates, it will drive the gear 8 to rotate synchronously. The upper and lower parts of the gear 8 are respectively meshed with the rack 81.

[0038] An adjustment component 9 is provided on one side of the control component 2. A drive component 91 is provided on one side of the adjustment component 9 and is connected to the rotating component 92 via a drive shaft 911. The drive component 91 can drive the rotating component 92 to rotate. A cross-shaped fixing groove 921 is provided on one side of the rotating component 92, which can cooperate with the fixing protrusion 45 at the end of the control rod 43. An opening button 922 is provided at the center of the fixing groove 921. A spring 93 is provided inside the rotating component 92, and the other end of the spring 93 contacts the end of the control rod 43.

[0039] like Figure 6 , Figure 7 As shown, the ratchet 42 engages with the pawl 5 located in the internal cavity of the control component 2. The pawl 5 is connected to the inside of the control component 2 via a torsion spring 51. When the ratchet 42 rotates clockwise ( Figure 7 (In the middle direction) drives the pawl 5 to rise, when the ratchet 42 rotates counterclockwise ( Figure 7 (In the middle direction) Pad 5 will restrict the rotation of ratchet 42; when ratchet 42 is separated from pad 5, pad 5 will move to the initial position (position in the figure) under the action of torsion spring 51;

[0040] like Figure 8 As shown, the elastic band 13 and the rack 81 are connected by a connector 82. When the gear 8 rotates, it will drive the racks 81 on the upper and lower sides to move towards each other, thereby causing the elastic bands 13 on both sides to contract inward into the control member 2, thereby causing the side straps 12 to contract.

[0041] The working principle of this utility model:

[0042] Manually adjust the workflow:

[0043] like Figure 9 As shown, when the device needs to be worn, by pressing the control wheel 4 inward, the control lever 43 compresses the spring 93, the ratchet 42 separates from the pawl 5, and the ratchet 42 enters the damping wheel 6. The user rotates the control wheel 4, and through the connection between the control protrusion 44 and the gear 8, the gear 8 is driven to rotate, thereby driving the racks 81 on both sides to move, so that the elastic band 13 moves to the appropriate position, and the length of the side strap 12 is in the appropriate position.

[0044] Then, the user pulls it outwards. At this time, the spring 93 will assist the user in pulling out the control wheel 4. At this time, the ratchet 42 may be restricted by the pawl 5 and cannot return to the initial position. The user needs to rotate the control wheel 4 slightly to both sides so that the notch of the ratchet 42 coincides with the pawl 5, so that the ratchet 42 and the pawl 5 are engaged. The pawl 5 will limit the rotation of the ratchet 42 in one direction. That is, at this time the ratchet 42 can only rotate in one direction. The elastic band 13 can only be contracted by rotating the control wheel 4. At this time, the side strap 12 can only be contracted inwards until the user thinks that the wearing is complete.

[0045] When it is necessary to loosen the side strap 12, the user needs to press the control wheel 4 inward to rotate and adjust it using the above method;

[0046] Automatically adjust workflow:

[0047] like Figure 10 As shown, when the ratchet 42 is in the damping wheel 6, the user continues to press the control wheel 4 inward, so that the end fixing protrusion 45 of the control lever 43 contacts the fixing groove 921, and continues to compress the spring 93. The fixing protrusion 45 will compress the opening button 922 inside the fixing groove 921, thereby opening the drive component 91 and the limiting component 3. The limiting block 33 inside the limiting component 3 will extend inward under the action of the telescopic shaft 34, so that the limiting block 33 enters the limiting groove 411 of the control wheel 4. At this time, the control wheel 4 can rotate but cannot extend or retract.

[0048] When the sensor inside the glasses 1 detects that the user's range of motion is too large (and during practical operations during training), the drive component 91 will drive the rotating component 92 to rotate, thereby driving the control lever 43 to rotate, thereby driving the gear 8 to rotate, driving the rack 81 to move in opposite directions, pulling the elastic band 13 to move into the control component 2, thereby tightening the side strap 12 to prevent the device from falling off when the user makes large movements;

[0049] When the sensor detects that the user's range of motion has returned to normal, the drive component 91 drives the rotating component 92 to return to normal, so that the side strap 12 returns to the tightness when it was first worn.

[0050] When the user needs to remove the device, press the off button 31 on the control component 2 to close the drive component 91 and the limit component 3. The limit component 3 drives the telescopic shaft 34 to retract, thereby separating the limit block 33 from the limit groove 411. The user can pull out the control wheel 4 to engage the ratchet 42 with the damping wheel 6. At this time, the user can loosen the side strap 12 by rotating the control wheel 4 to remove the device.

[0051] By adjusting the tightness of the straps in the two aforementioned devices, the ease of wearing the mixed reality glasses is increased, enabling precise matching for students with different head sizes and providing reliable hardware support for immersive training experiences.
