[0045] The following will describe in detail the specific implementation manners of the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present utility model, and are not used to limit the embodiments of the present utility model.

[0046] Figure 1 is a schematic structural diagram of a VR device for teaching according to an embodiment of the present utility model. In Figure 1 it, the VR device may include a VR eyepatch 1, two connecting bands 4, and two adjusting components. Specifically, the VR eyepatch 1 includes two fixing seats 3.

[0047] Both ends of the VR eyepatch 1 are provided with fixing seats 3, and one ends of the two connecting bands 4 are respectively connected to the two fixing seats 3. One ends of the two adjusting components are respectively connected to the other ends of the two connecting bands 4, and the other ends of the two adjusting components are connected to each other. The adjusting components are used to store or loosen the connecting bands 4, and cooperate with the two connecting bands 4 and the VR eyepatch 1 to form a head-mounted structure.

[0048] When a user needs to wear the VR device, first use the two adjusting components to store or loosen the two connecting bands 4 to adjust the total length of the connecting bands 4 and the adjusting components. After adjusting the two connecting bands 4 to an approximate length, the head-mounted structure formed by the two adjusting components, the two connecting bands 4 and the VR eyepatch 1 is put on the user's head. After the wearing is completed, further store and adjust the corresponding connecting band 4 through the adjusting component so that the VR eyepatch 1 can fit well with the user's head, thereby facilitating the user's practical training. After the practical training is over, loosen the corresponding connecting band 4 through the adjusting component to expand the head-mounted structure formed by the two adjusting components, the two connecting bands 4 and the VR eyepatch 1, so as to facilitate the removal of the VR eyepatch 1 from the user's head.

[0049] For traditional VR devices used in practical training, due to the diversity of users, they often cannot be well adjusted according to the size of the user's head, resulting in discomfort for the user during long-term wearing and easy damage to the skin. In this embodiment of the present utility model, the method of respectively storing or releasing the two connecting bands 4 by using two adjusting components can, on the one hand, be applicable to different users, with wider applicability, and on the other hand, can also facilitate the adjustment of a more suitable size after the user wears it, which is more convenient.

[0050] In this embodiment of the present utility model, as Figure 2 , Figure 3 and Figure 4 shown, the adjustment assembly may include a first adjustment plate 5, a second adjustment plate 6 and a limiting assembly. Specifically, the second adjustment plate 6 may include a receiving groove 18.

[0051] One end of the first adjustment plate 5 is connected to the other end of the corresponding connecting band 4. A receiving groove 18 is formed at one end of the second adjustment plate 6, and the other end of the first adjustment plate 5 extends into the interior of the receiving groove 18. The limiting assembly is arranged inside the receiving groove 18 for limiting and fixing the first adjustment plate 5.

[0052] When it is necessary to store or release the connecting band 4, move the first adjustment plate 5 so that the first adjustment plate 5 moves inside the receiving groove 18 of the second adjustment plate 6 and drives the connecting band 4 to move synchronously. When coarsely adjusting the size of the head-mounted structure in advance, when the first adjustment plate 5 reaches the appropriate position, it can be limited and fixed by the limiting assembly. After wearing the VR device on the user's head, further move the first adjustment plate 5 so that the first adjustment plate 5 gradually enters the interior of the receiving groove 18. At this time, the VR eye mask 1 gradually fits the user's head, and the connecting band 4 deforms adaptively and gradually fits the user's head. When the VR eye mask 1 fits the user's head well, that is, when a good wearing comfort is satisfied for the user, the first adjustment plate 5 can be fixed by the limiting assembly to maintain the current wearing state. By adopting the cooperation mode of the connecting band 4 and the first adjustment plate 5, on the one hand, the first adjustment plate 5 can adjust the overall length of the connecting band 4 and the first adjustment plate 5 to meet the wearing needs of different users; on the other hand, the connecting band 4 can also adapt to the changes in the head circumference sizes of different users to ensure the wearing comfort of different users.

[0053] In this embodiment of the present utility model, the connection mode between the first adjustment plate 5 and the receiving groove 18 may include a sliding connection. Specifically, a sliding groove is formed inside the receiving groove 18, and a sliding column / slider that is slidably matched with the sliding groove is arranged on the side wall of the first adjustment plate 5.

[0054] In this embodiment of the present utility model, as Figure 3 and Figure 4 shown, the limiting assembly may include a plurality of teeth 11, a clamping block 17 and a driving part.

[0055] A plurality of gear teeth 11 are arranged in an array on the top of the first adjusting plate 5. A clamping groove 12 is formed by cooperation between two adjacent gear teeth 11. The clamping block is arranged inside the receiving groove 18. One end of the driving part is connected to the top of the clamping block 17, and the other end of the driving part movably penetrates through the second adjusting plate 6. The driving part is used to drive the clamping plate to descend and cooperate with one of the clamping grooves 12 for clamping.

[0056] After the first adjusting plate 5 reaches a suitable position, press the driving part so that the clamping block 17 descends. The clamping block 17 gradually enters the inside of the clamping groove 12 below it and cooperates with the clamping groove 12 for clamping. At this time, due to the clamping limitation between the clamping block 17 and the clamping groove 12, the first adjusting plate 5 is limited and fixed, that is, the adjustment of the overall length of the connecting belt 4 and the first adjusting plate 5 is realized. By using the method of clamping and cooperating the clamping block 17 with the gear teeth 11, on the one hand, the clamping is stable, and on the other hand, the operation is simple, and the user can operate the driving by himself.

[0057] In this embodiment of the present utility model, for the cross-sectional shape of the gear teeth 11, that is, the cross-sectional shape of the clamping groove 12, it may include a square, a triangle, etc. known to those skilled in the art. However, in a preferred example of the present utility model, considering the reliability and effectiveness of the clamping and cooperation between the clamping block 17 and the clamping groove 12, the cross-sectional shape of the clamping groove 12 can be as shown in Figure 4. Specifically, in Figure 4 it, the cross-sectional shape of the clamping groove 12 may include an inverted trapezoid, and the cross-sectional shape of the clamping block 17 includes an inverted trapezoid. Specifically, the inclined surface of this kind of inverted trapezoid can facilitate guiding the clamping block 17 to the inner bottom of the clamping groove 12 and improve the stability of the clamping cooperation. In addition, when driving the clamping block 17 to disengage from the clamping cooperation with the corresponding clamping groove 12, move the first adjusting plate 5, and the inclined surface of the inverted trapezoid can be used to assist in pushing the clamping block 17 away from the clamping groove 12.

[0058] In this embodiment of the present utility model, a limiting plate is arranged at the other end of the first adjusting plate 5, that is, a limiting plate is arranged at the end of the first adjusting plate 5 located inside the receiving groove 18. The height of the limiting plate is greater than the height of the gear teeth 11 and is used to abut against the inner wall of the opening end of the receiving groove 18 to prevent the first adjusting plate 5 from disengaging from the inside of the receiving groove 18.

[0059] In this embodiment of the present utility model, as Figure 4 shown, the driving part may include a cylinder 16, a limiting opening 14, and an elastic body 15.

[0060] The bottom end of the cylinder 16 is connected to the clamping block 17, and the top end of the cylinder 16 has a movable rod passing through the second adjusting plate 6. A limit opening 14 is formed in the side wall of the second adjusting plate 6 and communicates with the storage groove 18. The elastic body 15 is in a right triangle shape, one of the right sides of the elastic body 15 is connected to the side wall of the cylinder 16, and the other right side of the elastic body 15 is used to cooperate with the inner top wall of the limit opening 14 for limiting.

[0061] When it is necessary to adjust the clamping position of the first adjusting plate 5, press the other right side of the elastic body 15 so that it is compressed and deformed and completely enters the interior of the storage groove 18. At the same time, pull the cylinder 16 upward, and cooperate to squeeze the elastic body 15 into the interior of the storage groove 18 and fit and abut against the inner wall of the storage groove 18. At this time, the clamping block 17 moves with the cylinder 16 and disengages from the corresponding clamping groove 12, and then the first adjusting plate 5 can be moved to adjust the length of the first adjusting plate 5 located inside the storage groove 18. After the first adjusting plate 5 reaches the preset position, press the cylinder 16 so that the clamping block 17 gradually enters the corresponding clamping groove 12. At this time, the compressed elastic body 15 moves accordingly until it resets in the limit opening 14, and the other right side of the elastic body 15 fits against the inner top wall of the limit opening 14. Since the contact surface between the other right side of the elastic body 15 and the inner top wall of the limit opening 14 is large, the position of the cylinder 16 can be effectively limited, that is, the state of the clamping block 17 being clamped in cooperation with the corresponding clamping groove 12 can be effectively maintained. The method of using the right triangle-shaped elastic body 15 in cooperation with the limit opening 14 improves the ease of operation of limiting and fixing the first adjusting plate 5 on the one hand, and also improves the stability of limiting and fixing the first adjusting plate 5 on the other hand.

[0062] In this embodiment of the present invention, for the specific material of the elastic body 15, considering its elastic reset ability and the non-directionality of deformation, the material of the elastic body 15 may include rubber.

[0063] In this embodiment of the present invention, considering the stability and reliability of the limit component for limiting and fixing the first adjusting plate 5, the limit component may include two groups. Specifically, the two groups of limit components are respectively arranged at the top and bottom of the first adjusting plate 5. Specifically, a plurality of gear teeth 11, a clamping portion, and a driving portion are arranged at both the top and bottom of the first adjusting plate 5.

[0064] In this embodiment of the present invention, as Figure 3 and Figure 4 shown, the cylinder 16 may include a pressing plate 13. Specifically, a pressing plate 13 is arranged at one end of the cylinder 16 away from the clamping block 17. Specifically, the pressing plate 13 facilitates the user's pressing operation and is more comfortable.

[0065] In this embodiment of the present invention, asFigure 1 As shown, the VR device may further include two connecting parts 7, two first elastic bands 9, and a head cover plate 10.

[0066] The two connecting parts 7 are respectively vertically connected to the two second adjusting plates 6. The head cover plate 10 is located above the middle of the two connecting parts 7. The head cover plate 10 is respectively connected to the tops of the two connecting parts 7 through the two first elastic bands 9.

[0067] When the user wears it, the head cover plate 10 can fit on the top of the user's head, and through the elastic force of the second elastic band 8, it can adaptively adjust the length to adapt to the different head sizes of different users. The cooperation of the head cover plate 10 and the two first elastic bands 9 can, on the one hand, improve the wearing stability of the user, and on the other hand, can also protect the user's head.

[0068] In this embodiment of the present invention, earphones may also be provided on the opposite sides of the two connecting parts 7. The cooperation of the earphones and the VR eye mask 1 can improve the training experience of the user.

[0069] In this embodiment of the present invention, as Figure 1 shown, the other ends of the two adjusting components are connected by a second elastic band 8. Specifically, the other ends of the two second adjusting plates 6 are connected by a second elastic band 8. The method of connecting the two second adjusting plates 6 by the second elastic band 8 can facilitate the use of different head circumferences of different users and further ensure the wearing stability of the VR eye mask 1.

[0070] In this embodiment of the present invention, for the specific structures of the first elastic band 9 and the second elastic band 8, it may include but is not limited to the milk tape known to those skilled in the art.

[0071] In this embodiment of the present invention, as Figure 1 shown, a sponge pad 2 is provided at the edge of the VR eye mask 1. Specifically, the sponge pad 2 can reduce the skin damage to the user and improve the wearing comfort of the user.

[0072] Through the above technical solutions, a VR device for teaching provided by the present invention releases or retracts the two connecting bands 4 to a general length through the two adjusting components, and then puts the head-mounted structure formed by the cooperation of the two adjusting components, the two connecting bands 4, and the VR eye mask 1 on the user's head. After the head-mounted is completed, control the two adjusting components to retract the two connecting bands 4 until the VR eye mask 1 fits the user's head; the method of respectively retracting or releasing the two connecting bands 4 by the two adjusting components can, on the one hand, be applicable to the use of different users, with a wider applicability, and on the other hand, can also facilitate the adjustment of a more suitable size after the user wears it, which is more convenient.
