Description

Technical Field

[0001] This invention relates to the field of VR device technology, and in particular to a strap adjustment device and a VR device. Background Technology

[0002] With the advancement of technology, VR (Virtual Reality) technology is attracting increasing attention from users. VR is a computer simulation system that can create and experience virtual worlds. It can use computers to generate a simulated environment and, through the fusion of multi-source information and interactive three-dimensional dynamic visuals and physical behavior system simulation, immerse users in the virtual environment and experience a sense of being in a real world.

[0003] Currently, VR functionality is primarily achieved through VR devices, such as head-mounted displays (VR headsets). A VR headset uses a head-mounted display to isolate the user's vision and hearing from the outside world, creating a feeling of being in a virtual environment. The display principle of a head-mounted display is that the left and right screens display images from the left and right sides respectively. The user's eyes receive this differentiated information and combine it in their mind to create a sense of depth. In practical applications, VR headsets can take various forms, such as VR boxes and VR helmets. However, whether it's a VR box or a VR helmet, the user needs to wear the VR device on their head and tighten the straps to ensure a tight fit to their head shape before any further operation can begin.

[0004] However, most current strap adjustment mechanisms use knobs for adjustment, which is relatively awkward to operate when wearing a VR headset and rotating the knob behind the head with the hand behind the head. This is especially inconvenient for people with hand movement disorders. When the strap is released to its maximum, the knob needs to be rotated multiple times, which is not quick enough. Summary of the Invention

[0005] The main objective of this invention is to provide a strap adjustment device and a VR device, aiming to solve the technical problem of inconvenient strap size adjustment in existing VR devices.

[0006] To achieve the above objectives, the present invention provides a strap adjustment device, the strap adjustment device comprising: The upper shell has a receiving cavity inside, and a sliding groove is provided on the side wall of the upper shell, the sliding groove communicating with the receiving cavity; A strap assembly disposed within the receiving cavity; A sliding component, which is movably disposed on the slide groove; A connector, one end of which is connected to the sliding assembly, and the other end of which extends toward the strap assembly; A driving component is disposed on the sliding component and connected to the connector; The drive component is used to drive the connector to move to abut against the strap assembly, or to drive the connector to retract from the strap assembly; When the connector comes into contact with the strap assembly, the sliding component slides and causes the strap assembly to retract.

[0007] Optionally, the strap assembly includes a gear, a first strap, and a second strap. The first strap and the second strap are disposed opposite to each other in the receiving cavity. A first rack is provided on the side of the first strap facing the second strap, and a second rack is provided on the side of the second strap facing the first strap. The gear meshes between the first rack and the second rack. A third rack is provided on the side of the second rack facing the slide groove, and the driving assembly is used to drive the connector to move to abut against the third rack.

[0008] Optionally, the sliding component includes: Guide rod, the guide rod being disposed within the slide groove; A slider, which is movably mounted on the guide rod; A reset component, one end of which is connected to the end of the guide rod, and the other end of which is connected to the slider; The connector is disposed on the side of the slider facing the strap assembly, and the drive assembly is disposed on the side of the slider away from the strap assembly. The drive assembly is connected to the connector.

[0009] Optionally, the first strap and the second strap are made of a resilient plastic material.

[0010] Optionally, the reset element is a spring.

[0011] Optionally, the driving component includes: A button is provided on the side of the slider opposite to the strap assembly; A torsion spring is disposed on the side of the slider facing the strap assembly, and the connector is connected to the torsion spring; A first magnet block is disposed on the side of the button facing the connector; A second magnet block is disposed on the connector; When the button is pressed, it causes the first magnet to move toward the connector, so that the first magnet attracts the second magnet and causes the connector to retract from the strap assembly. When the button is released, it causes the first magnet to move away from the connector, so that the first magnet is disengaged from the second magnet, and the connector moves to abut against the strap assembly via the torsion spring.

[0012] Optionally, the button has a first mounting groove on the side facing the connector, and the first magnet is disposed in the first mounting groove.

[0013] Optionally, the connector has a second mounting groove on the side facing the slider, and the second magnet block is disposed in the second mounting groove.

[0014] Optionally, the upper shell has an opening that communicates with the slide groove, and the button extends out of the upper shell through the opening.

[0015] In addition, to solve the above problems, the present invention also proposes a VR device, wherein the VR device applies the strap adjustment device as described above.

[0016] The present invention provides a first snap-fit ​​hole and a second snap-fit ​​hole at different positions on the sleeve, and correspondingly provides a first buckle and a second buckle on the elastic snap-fit ​​mechanism. Through the mutual cooperation of the first snap-fit ​​hole and the first buckle, and the mutual cooperation of the second snap-fit ​​hole and the second buckle, different types of connectors can be snapped together. The overall structure is simple and compact, greatly improving the utilization of structural space, and allowing for quick disassembly and interchange of connectors. Attached Figure Description

[0026] This invention proposes a strap adjustment device, comprising an upper shell 10, a strap assembly 20, a sliding assembly 30, a connector 50, and a driving assembly 40. The upper shell 10 has a receiving cavity 13, and a sliding groove 12 is provided on the side wall of the upper shell 10, the sliding groove 12 communicating with the receiving cavity 13. The strap assembly 20 is disposed within the receiving cavity 13. The sliding assembly 30 is movably disposed on the sliding groove 12. One end of the connector 50 is connected to the sliding assembly 30, and the other end extends toward the strap assembly 20. The driving assembly 40 is disposed on the sliding assembly 30 and is connected to the connector 50. The driving assembly 40 is used to drive the connector 50 to move to abut against the strap assembly 20, or to drive the connector 50 to retract from the strap assembly 20. When the connector 50 abuts against the strap assembly 20, the sliding assembly 30 slides and causes the strap assembly 20 to retract.

[0027] Please refer to Figure 1 The sliding assembly 30 is mounted on the outer side of the upper shell 10. Specifically, the upper shell 10 has an opening 11 that communicates with the sliding groove 12. The sliding assembly 30 is mounted in the opening 11. The opening 11 is larger to facilitate the reciprocating movement of the sliding assembly 30 within it.

[0028] The sliding component 30 extends out of the upper shell 10 through the opening 11. The sliding component 30 is exposed outside the upper shell 10, which facilitates interaction with the sliding component 30 by hand to achieve the operation of tightening and loosening the strap.

[0029] Please refer to Figure 2 The strap assembly 20 is installed in the receiving cavity 13 inside the upper shell 10 to avoid interference with other mechanisms that may affect contraction.

[0030] The two ends of the strap assembly 20 extend out of the upper shell 10 and are connected to the headband 60 for the user to wear on their head.

[0031] The connector 50 is used to connect the strap assembly 20 and the sliding assembly 30. This allows the sliding assembly 30 to move the strap assembly 20 during sliding, thereby causing the external headband 60 to retract synchronously.

[0032] As one embodiment, the strap assembly 20 can be fixed at one end to the upper shell 10, and the other end connected to the connector 50. When the sliding assembly 30 moves the connector 50, it pulls the other end of the strap assembly 20 to move. Please refer to... Figure 1When the sliding component 30 moves to the left, the strap component 20 tightens; when it is pulled to the right, the strap component 20 loosens. This method has a simple and compact structure, but a relatively small adjustment range.

[0033] Therefore, please refer to Figure 2 In another embodiment, the strap assembly 20 may include a first strap 21 and a second strap 22. The first strap 21 is used to connect to one end of the outer headband 60, and the second strap 22 is used to connect to the other end of the outer headband 60. Through the engagement of the gear 23, when the sliding assembly 30 moves to the left, the two straps move towards each other, thereby tightening both ends of the outer headband 60 simultaneously. When it moves to the right, the two straps move away from each other, thereby loosening both ends of the outer headband 60 simultaneously. This method can significantly increase the adjustment range and improve product compatibility.

[0034] The drive component 40 is used to drive the connection between the connector 50 and the strap component 20.

[0035] When the user finishes using the product and needs to restore the external headband 60 to its initial length, the connecting piece 50 can be disengaged from the strap assembly 20 via the drive component 40. This achieves the reset of the strap assembly 20.

[0036] To enable the strap assembly 20 to have a reset function, the strap in the strap assembly 20 can be made of a material with elasticity, such as plastic. Alternatively, a structure such as a spring can also be used to achieve the reset function.

[0037] The present invention provides a first snap-fit ​​hole and a second snap-fit ​​hole at different positions on the sleeve, and correspondingly provides a first buckle and a second buckle on the elastic snap-fit ​​mechanism. Through the mutual cooperation of the first snap-fit ​​hole and the first buckle, and the mutual cooperation of the second snap-fit ​​hole and the second buckle, different types of connectors can be snapped together. The overall structure is simple and compact, greatly improving the utilization of structural space, and allowing for quick disassembly and interchange of connectors.

[0038] For details, please refer to Figure 3The following description uses the strap assembly 20, which includes the first strap 21 and the second strap 22, as an example. The strap assembly 20 includes a gear 23, a first strap 21, and a second strap 22. The first strap 21 and the second strap 22 are disposed opposite each other in the receiving cavity 13. A first rack 211 is provided on the side of the first strap 21 facing the second strap 22, and a second rack 221 is provided on the side of the second strap 22 facing the first strap 21. The gear 23 meshes between the first rack 211 and the second rack 221. A third rack 222 is provided on the side of the second rack 221 facing the slide groove 12. The driving assembly 40 is used to drive the connector 50 to move to abut against the third rack 222.

[0039] In this embodiment, both the first strap 21 and the second strap 22 are made of materials such as polyethylene, thereby giving them elasticity and plasticity.

[0040] The gear 23 is clamped between the first strap 21 and the second strap 22. The gear 23 also meshes with the first rack 211 and the second rack 221. Therefore, when the gear 23 rotates, it drives the first strap 21 and the second strap 22 to move towards or away from each other.

[0041] The third rack 222 can be arbitrarily disposed on the first strap 21 or on the second strap 22. In this embodiment, the third rack 222 is disposed on the second strap 22 as an example.

[0042] When the drive assembly 40 drives the connector 50 to move to abut against the second strap 22, the connector 50 is engaged in the tooth groove of the third rack 222. When the sliding assembly 30 drives the connector 50 to move, the second strap 22 can be moved through the engaged tooth groove. Under the action of the gear 23, the first strap 21 is moved synchronously.

[0043] When the drive assembly 40 drives the connector 50 to disengage from the tooth groove, the limiting effect of the connector 50 on the second strap 22 disappears. Under the elastic plasticity of the second strap 22, the second strap 22 resets and drives the first strap 21 to reset synchronously through the gear 23.

[0044] Further, the sliding assembly 30 includes a guide rod 31, a slider 32, and a reset member 33. The guide rod 31 is disposed within the slide groove 12. The slider 32 is movably disposed on the guide rod 31. One end of the reset member 33 is connected to the end of the guide rod 31, and the other end is connected to the slider 32. The connecting member 50 is disposed on the side of the slider 32 facing the strap assembly 20, and the driving assembly 40 is disposed on the side of the slider 32 away from the strap assembly 20. The driving assembly 40 is connected to the connecting member 50.

[0045] To adapt to the curve of the user's head, the guide rod 31 is arc-shaped. The two ends of the guide rod 31 are respectively fixed to the left and right side walls of the slide groove 12.

[0046] The slider 32 has a through hole, and the guide rod 31 passes through the through hole, thereby enabling the slider 32 to slide on the guide rod 31.

[0047] The reset component 33 can be a spring, sleeved on the guide rod 31, with one end connected to the end of the guide rod 31 or to one side wall of the slide groove 12, and the other end connected to the slider 32.

[0048] Please refer to Figure 2 The reset member 33 is disposed between the slider 32 and the left side wall of the slide groove 12. The user moves the slider 32 to the left to adjust the tightness of the strap assembly 20. After the user relieves the force on the slider 32, the slider 32 will be pushed to the right to its initial position by the reset member 33.

[0049] With the cooperation of the third rack 222, the connector 50 is pushed into the tooth groove on the right side of the third rack 222 by the reset member 33, thereby limiting the second strap 22.

[0050] If the user wants to further tighten the strap assembly 20, they can continue to push the slider 32 to the left, where it will reset under the action of the reset member 33. This process can be repeated multiple times by pushing the slider 32 to the left until the desired tightness is achieved.

[0051] In this embodiment, the slider 32 is reset by the reset member 33, and in conjunction with the third rack 222, the user can adjust the tightness multiple times, further improving the product's compatibility.

[0052] In another embodiment, a button 41 is installed on the outward side of the slider 32, and the connector 50 is installed at the bottom of the button 41. When the user presses the button 41, the connector 50 is pushed inward toward the upper shell 10, eventually abutting against the strap assembly 20. When the user switches the button 41 back, the connector 50 disengages from the strap assembly 20 along with the button 41.

[0053] As another embodiment, please refer to Figure 4 The drive assembly 40 includes a button 41, a torsion spring 42, a first magnet 43, and a second magnet 44. The button 41 is located on the side of the slider 32 facing away from the strap assembly 20. The torsion spring 42 is located on the side of the slider 32 facing the strap assembly 20, and the connector 50 is connected to the torsion spring 42. The magnet is located on the side of the button 41 facing the connector 50. The second magnet 44 is located on the connector 50. When the button 41 is pressed, it causes the first magnet 43 to move towards the connector 50, so that the first magnet 43 attracts the second magnet 44, and causes the connector 50 to retract from the strap assembly 20. When the button 41 is released, it causes the first magnet 43 to move away from the connector 50, so that the first magnet 43 disengages from the second magnet 44, and the connector 50 moves through the torsion spring 42 to abut against the strap assembly 20.

[0054] In contrast, in this embodiment, when the user presses the button 41, the first magnet 43 is pushed toward the side of the strap assembly 20, the attraction between the first magnet 43 and the second magnet 44 increases, and overcomes the resistance of the torsion spring 42, so that the first magnet 43 attracts the second magnet 44, thereby the connector 50 disengages from the third rack 222, and the strap assembly 20 is reset.

[0055] When the user does not press the button 41, the first magnet 43 moves in the opposite direction, increasing the distance between it and the second magnet 44, thus reducing the attraction force. Under the action of the torsion spring 42, the connector 50 is pushed towards the third rack 222 and engages in the tooth groove of the third rack 222, thus limiting the position of the strap assembly 20.

[0056] This method allows users to adjust the tightness of the strap assembly 20 without touching the button 41; to reset it, simply press the button 41. This further improves user convenience and enhances structural rationality.

[0057] Specifically, the slider 32 has a certain thickness to accommodate the first magnet block 43. The button 41 has a first mounting groove 45 on the side facing the connector 50, and the first magnet block 43 is disposed in the first mounting groove 45.

[0058] The connector 50 has a second mounting groove 51 on the side facing the slider 32, and the second magnet block 44 is disposed in the second mounting groove 51. A protruding boss is provided on the side of the connector 50 facing the slider 32, and the inside of the boss is hollowed out, thereby realizing the fabrication of the second mounting groove 51.

[0059] Furthermore, to address the aforementioned problems, this invention also proposes a VR device that utilizes the aforementioned strap adjustment device. The sliding assembly 30 is mounted on the outer side of the upper shell 10. Specifically, the upper shell 10 has an opening 11 that communicates with the sliding groove 12. The sliding assembly 30 is mounted within the opening 11. The opening 11 is larger to facilitate reciprocating movement of the sliding assembly 30 within it.

[0060] The sliding component 30 extends out of the upper shell 10 through the opening 11. The sliding component 30 is exposed outside the upper shell 10, which facilitates interaction with the sliding component 30 by hand to achieve the operation of tightening and loosening the strap.

[0061] The strap assembly 20 is installed in the receiving cavity 13 inside the upper shell 10 to avoid interference with other mechanisms that could affect contraction.

[0062] The two ends of the strap assembly 20 extend out of the upper shell 10 and are connected to the headband 60 for the user to wear on their head.

[0063] The connector 50 is used to connect the strap assembly 20 and the sliding assembly 30. This allows the sliding assembly 30 to move the strap assembly 20 during sliding, thereby causing the external headband 60 to retract synchronously.

[0064] As one embodiment, the strap assembly 20 can be fixed at one end to the upper shell 10, and the other end connected to the connector 50. When the sliding assembly 30 moves the connector 50, it pulls the other end of the strap assembly 20 to move. Please refer to... Figure 1 When the sliding component 30 moves to the left, the strap component 20 tightens; when it is pulled to the right, the strap component 20 loosens. This method has a simple and compact structure, but a relatively small adjustment range.

[0065] Therefore, as another embodiment, the strap assembly 20 may include a first strap 21 and a second strap 22. The first strap 21 is used to connect to one end of the outer headband 60, and the second strap 22 is used to connect to the other end of the outer headband 60. Through the engagement of the gear 23, when the sliding assembly 30 moves to the left, the two straps move towards each other, thereby tightening both ends of the outer headband 60 simultaneously. When it moves to the right, the two straps move away from each other, thereby loosening both ends of the outer headband 60 simultaneously. This method can significantly increase the adjustment range and improve product compatibility.

[0066] The drive component 40 is used to drive the connection between the connector 50 and the strap component 20.

[0067] When the user finishes using the product and needs to restore the external headband 60 to its initial length, the connecting piece 50 can be disengaged from the strap assembly 20 via the drive component 40. This achieves the reset of the strap assembly 20.

[0068] To enable the strap assembly 20 to have a reset function, the strap in the strap assembly 20 can be made of a material with elasticity, such as plastic. Alternatively, a structure such as a spring can also be used to achieve the reset function.

[0069] The present invention provides a first snap-fit ​​hole and a second snap-fit ​​hole at different positions on the sleeve, and correspondingly provides a first buckle and a second buckle on the elastic snap-fit ​​mechanism. Through the mutual cooperation of the first snap-fit ​​hole and the first buckle, and the mutual cooperation of the second snap-fit ​​hole and the second buckle, different types of connectors can be snapped together. The overall structure is simple and compact, greatly improving the utilization of structural space, and allowing for quick disassembly and interchange of connectors.

[0070] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
