DETAILED DESCRIPTION

[0035] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numbers in the drawings represent elements or components having the same function or similar functions. Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0036] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0037] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0038] Please see Figures 1-10 In this embodiment of the invention, an intelligent VR glasses that can be worn automatically and quickly includes a glasses body 1 and straps 3 symmetrically arranged at both ends of the glasses body 1, wherein the straps 3 are made of polyester fiber with high strength, wear resistance and elasticity.

[0039] One end of the strap 3 is rotatably connected to the eyeglass body 1 via a hinge shaft 4, and the rotation of the hinge shaft 4 is controlled by a drive assembly located inside the protective cover 2 on the eyeglass body 1.

[0040] It also includes an inflation assembly disposed on the strap 3, the inflation assembly being connected to an airbag 11 disposed inside the strap 3;

[0041] A pressure detection device is installed on the strap 3. When the strap 3 is deflected for wearing, the airbag 11 is inflated and squeezed by the head. When the pressure detection device detects that the air pressure inside the airbag 11 reaches a threshold, it drives the elastic trigger installed on the strap 3 to work. When the sensor panel 18 set on the strap 3 is touched, it sends a signal to the inflation component and the drive component.

[0042] In this embodiment of the invention, when the VR glasses are worn, after the glasses body 1 is close to the human eye, the drive component is activated, causing the two straps 3 to deflect synchronously towards the head. Simultaneously, the inflation component inflates the airbag 11, causing it to expand. After the straps 3 deflect to contact the head, the airbag 11 is compressed by the head, further increasing the internal pressure. At this point, the straps 3 gradually tighten around the head. Once the internal pressure of the airbag 11 exceeds the preset pressure of the pressure detection element, the pressure detection element is activated to compress the elastic trigger element. When the internal pressure of the airbag 11 reaches a threshold, this... The head strap 3 can be securely worn on the head. Depending on the head size, the time it takes for the pressure inside the airbag 11 to reach the threshold is also different. This causes the elastic potential energy stored in the elastic trigger to be released instantly and quickly for the sensing panel 18. The sensing panel 18 sends signals to the inflation component and the drive component, so that when the head strap 3 stops deflecting, the inflation component also stops inflating the airbag 11. This avoids the head strap 3 from being too tight and causing a decrease in the wearer's comfort. At the same time, it can quickly put on the VR glasses for wearers with different head sizes and ensure the wearing effect when using the VR glasses.

[0043] As a further embodiment of the present invention, please refer to... Figure 4 The drive assembly includes a connecting shaft 8 rotatably mounted on the protective cover 2. The connecting shaft 8 is driven to rotate by a reduction motor disposed inside the protective cover 2. The two ends of the connecting shaft 8 are respectively connected to the hinge shaft 4 and the transmission shaft 6 rotatably disposed inside the protective cover 2 through a bevel gear set 7. The transmission shaft 6 is connected to another hinge shaft 4 through a gear set 5.

[0044] It should be noted that the hinge shaft 4 rotates at a very small angle, so a reduction motor is required to drive it. This allows the strap 3 to be precisely adjusted to achieve a satisfactory effect for the wearer when it is deflected and tightened towards the head. The specific reduction motor is not shown in the diagram and is existing technology, so it will not be explained further in this invention.

[0045] Specifically, when the reduction motor is started, it can drive the connecting shaft 8 to rotate. The connecting shaft 8 drives one of the hinge shafts 4 and the transmission shaft 6 to rotate through the bevel gear sets 7 at both ends. Under the transmission of the gear set 5, the transmission shaft 6 drives the other hinge shaft 4 to rotate synchronously. Thus, the two hinge shafts 4 rotate synchronously in opposite directions, so that the two straps 3 can be simultaneously deflected toward the head to tighten the head.

[0046] As a further embodiment of the present invention, please refer to... Figure 5 The inflation assembly includes a first box 9 fixedly mounted on the strap 3. A cavity communicating with the airbag 11 is formed inside the first box 9. A first piston plate 12 is slidably mounted inside the cavity, and a threaded sleeve 13 is fixedly mounted on the first piston plate 12. The movement of the threaded sleeve 13 is controlled by a threaded drive component disposed inside the first box 9.

[0047] The threaded drive component includes a threaded rod 14, which is rotatably mounted inside the first housing 9 via a mounting plate 16. The threaded rod 14 is threadedly connected to the threaded sleeve 13, and the threaded rod 14 is driven to rotate by a micro motor 15 fixedly installed inside the first housing 9.

[0048] Preferably, the first box 9 is not a sealed chamber. Only the sealed chamber formed by the first piston plate 12 and the inside of the first box 9 is connected to the airbag 11. When the first piston plate 12 moves relative to the first box 9, the air pressure in the sealed chamber changes, thereby controlling the inflation of the airbag 11.

[0049] While the aforementioned reduction motor starts working, it controls the micro motor 15 to work synchronously. The output shaft of the micro motor 15 is fixed to the threaded rod 14, so that when the output shaft works, it drives the threaded rod 14 to rotate synchronously. When the threaded rod 14 rotates, it drives the threaded sleeve 13 to move linearly along the axis of the threaded rod 14, thereby squeezing the first piston plate 12 to move within the first housing 9. The first piston plate 12 forms a sealed chamber with the inner wall of the first housing 9. The movement of the first piston plate 12 can change the pressure of the sealed chamber. When the first piston plate 12 moves toward the sealed chamber, it can squeeze the air pressure in the sealed chamber into the airbag 11 to inflate the airbag 11, causing the airbag 11 to expand.

[0050] It should be noted that when the strap 3 deflects to squeeze the wearer's head, causing the air pressure inside the airbag 11 to increase further, the air pressure inside the airbag 11 cannot be squeezed into the sealed chamber under the self-locking action of the threaded rod 14 and the threaded sleeve 13, and instead acts on the pressure detection device.

[0051] As a further embodiment of the present invention, please refer to... Figure 6 and Figure 7 The outer end of the strap 3 is provided with a second box 10, and a placement cavity is formed inside the second box 10. The pressure detection element and the elastic trigger element are disposed in the placement cavity.

[0052] The pressure detection device includes a pressure box 17 fixedly installed in the placement cavity and connected to the airbag 11. A second piston plate 19 is slidably and sealed in the pressure box 17 along the length direction. A movable shaft 22 is fixedly installed at one end of the second piston plate 19. One end of the movable shaft 22 passes through the pressure box 17 and extends out of the pressure box 17.

[0053] It also includes a first spring 23, which is sleeved on the movable shaft 22. One end of the first spring 23 abuts against the second piston plate 19, and the other end abuts against the inner end of the second housing 10.

[0054] Preferably, a first push rod 2201 and a second push rod 2202 are respectively provided on one end of the movable shaft 22 extending out of the second housing 10, and the first push rod 2201 and the second push rod 2202 can respectively abut against the elastic trigger.

[0055] Preferably, at least one set of limiting blocks 1701 are provided in the pressure box 17. The limiting blocks 1701 are mainly used to limit the second piston plate 19 to prevent the elastic force generated by the first spring 23 on the second piston plate 19 from driving the second piston plate 19 to squeeze the air pressure in the pressure box 17 into the airbag 11.

[0056] In the initial state, the first spring 23 is in a compressed state. In order to avoid the air pressure in the airbag 11 from squeezing the second piston plate 19 to move before the strap 3 comes into contact with the patient's head when the pressure inside the airbag 11 increases, thereby affecting the detection accuracy of the pressure detection device.

[0057] In detail, when the strap 3 deflects to contact the wearer's head, the pressure inside the airbag 11 increases further. When the pressure inside the airbag 11 exceeds the elastic potential energy of the first spring 23, the second piston plate 19 is squeezed, causing the movable shaft 22 to move toward the elastic trigger. The first spring 23 is further compressed until the pressure inside the airbag 11 reaches the threshold. The force generated on the elastic trigger by the movable shaft 22 enables the elastic trigger to act quickly on the sensing panel 18. At this time, the strap 3 is completely tightened around the wearer's head. After the sensing panel 18 sends a signal to the reduction motor, it stops the strap 3 from deflecting further and maintains the tightness of the strap 3 around the head.

[0058] As a further embodiment of the present invention, please refer to... Figure 9 and Figure 10 The elastic trigger includes a support block 20 fixedly installed inside the second housing 10. A deflection rod 21 is rotatably mounted on the support block 20. The two ends of the deflection rod 21 can respectively abut against the first push rod 2201 and the second push rod 2202.

[0059] It also includes a second spring 24, one end of which abuts against the deflection rod 21 and the other end of which abuts against the support block 20.

[0060] Preferably, the support block 20 is provided with a first abutment block 2001 and a second abutment block 2002 at both ends to limit the deflection rod 21.

[0061] In the initial state, the second spring 24 is in a stretched state. At this time, the stretch of the second spring 24 is at its minimum value. The second spring 24 generates a force on the deflection rod 21 to rotate toward the first abutment block 2001. Under the action of the first abutment block 2001, the deflection rod 21 cannot rotate toward the first abutment block 2001.

[0062] In detail, when the aforementioned movable shaft 22 moves, if the compressive force generated by the movable shaft 22 is greater than the elastic force of the second spring 24, it can drive the deflection rod 21 to rotate toward the second abutment block 2002. When the deflection rod 21 rotates to be on the same horizontal line as the support block 20, the tension of the second spring 24 is at its maximum value, but the force is balanced between the deflection rod 21 and the support block 20. At this time, the air pressure in the airbag 11 has not yet reached the threshold. When the strap 3 continues to deflect until it is completely tight around the wearer's head, the air pressure in the airbag 11 continues to increase until it reaches the threshold. Then, the movable shaft 22 continues to move until the deflection rod 21 and the support block 20 are in a state of balance. Once the state is released, under the elastic force of the second spring 24, the second spring 24 generates a force on the deflection rod 21 toward the second abutment block 2002, causing the deflection rod 21 to deflect rapidly toward the second abutment block 2002. During the deflection process, it acts on the sensing panel 18, causing the sensing panel 18 to be touched and send signals to the reduction motor and micro motor 15 respectively, so that the strap 3 stops deflecting the head and keeps the wearer's head in a tight state. It can quickly tighten the head of wearers with different head shapes and sizes, and can automatically maintain the tightness after tightening, ensuring the wearer's wearing comfort.

[0063] It should be noted that: In the initial state, when the air pressure inside the airbag 11 increases to a level greater than the elastic potential energy of the second spring 24, the second piston plate 19 drives the movable shaft 22 to move toward the deflection rod 21. At this time, the first push rod 2201 and the deflection rod 21 are in contact. The first push rod 2201 squeezes the deflection rod 21, causing the deflection rod 21 to deflect. Subsequently, under the action of the second spring 24, when the deflection rod 21 deflects to contact the second contact block 2002, the other end of the deflection rod 21 contacts the second push rod 2202, so that after the air pressure inside the airbag 11 decreases, the second push rod 2202 can drive the deflection rod 21 to return to its original position.

[0064] Preferably, the sensing panel 18 establishes communication with the reduction motor and the micro motor 15 respectively.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
