DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please see Figures 1-5 One embodiment provided by the present invention:

[0023] A motion behavior cognitive device integrating spatiotemporal contextual attention mechanism includes a VR device body 1. Fixing blocks 11 are fixedly connected to both sides of the VR device body 1. A female buckle 12 is fixedly connected inside the fixing blocks 11. A headband 2 is installed at one end of the VR device body 1. A protective pad 21 is fixedly connected to the front end of the headband 2. A locking structure 3 is provided inside the headband 2. The locking structure 3 includes a knob 31. A worm gear 32 is fixedly connected to the surface of the knob 31. A worm wheel 33 meshes with the surface of the worm gear 32. The worm wheel 33 is fixedly connected inside. The headband 2 has a threaded rod 34, with two sets of sliding blocks 35 slidably connected to its surface. Anti-slip pads 36 are fixedly connected to both sides of the sliding blocks 35. Two sets of sliding grooves 37 are symmetrically formed inside the headband 2. Storage structures 4 are provided on both sides of the headband 2. The storage structure 4 includes a storage groove 41, with mounting grooves 42 at the top and bottom. A rotating rod 43 is rotatably connected inside the storage groove 41. Limit blocks 44 are fixedly connected to the top and bottom of the rotating rod 43. Two sets of coil springs 45 are symmetrically fixedly connected to the surface of the rotating rod 43. The surface of the moving rod 43 is wound with a strap 46, one end of which is fixedly connected to a male buckle 47. A locking structure 3 is provided, which realizes stepless, linear and self-locking fine adjustment of the tightness of the headband 2. The worm gear 33 and worm 32 transmission have a reverse self-locking characteristic, which can prevent the headband 2 from being accidentally loosened due to head movements during use, ensuring the stability of wearing. At the same time, the bidirectional threaded rod 34 drives two sets of sliding blocks 35 to move synchronously in opposite directions or in opposite directions, which can apply pressure evenly to the limiting block 44, thereby clamping the limiting block 44. The fixed length of the strap 46 improves wearing comfort and fit. The storage structure 4 allows the strap 46 to be automatically and neatly rolled into the storage slot 41 when not in use, effectively preventing the strap 46 from being exposed, tangled, knotted, or covered in dust. This improves the portability and appearance of the device. When needed, simply pull out the strap 46 and fasten the male buckle 47 with the female buckle 12. The operation is simple and quick. After releasing, the restoring force of the coil spring 45 automatically retracts the strap 46, simplifying the usage steps and improving the user experience.

[0024] Furthermore, the male buckle 47 and the female buckle 12 cooperate with each other, with the male buckle 47 snapping into the female buckle 12 to achieve quick connection and separation between the strap 46 and the VR device body 1, thereby facilitating the user to wear and remove the device.

[0025] Further, the surface of the threaded rod 34 is provided with two sets of opposite threads, two sets of sliding blocks 35 are respectively matched with the two sets of threads, and the two sets of sliding blocks 35 are respectively slidably connected in the two sets of sliding grooves 37. The two sets of sliding blocks 35 are respectively matched with the two sets of threads to realize synchronous forward or backward movement, so as to stably expand or contract to adapt to different head circumferences. The sliding blocks 35 are limited by the sliding grooves 37 to prevent unnecessary rotation of the sliding blocks 35.

[0026] Further, the radius of the limiting block 44 is greater than the radius of the rotating rod 43, the limiting block 44 is rotatably connected in the two sets of sliding grooves 37 at the top and the bottom, the end of the rotating rod 43 penetrates the receiving groove 41, the mounting groove 42 and the sliding groove 37 and is fixedly connected with the limiting block 44, preventing the rotating rod 43 from being axially detached from the receiving groove 41 and ensuring stable work of the receiving structure 4.

[0027] Further, the protective pad 21 is arc-shaped, better fits the curve of the user's head, the cross section of the anti-skid pad 36 is greater than that of the limiting block 44, providing a larger contact area to enhance friction and prevent sliding, and the protective pad 21 and the anti-skid pad 36 are both made of rubber material, improving the wearing comfort and protecting the skin.

[0028] Further, the two ends of the coil spring 45 are respectively fixedly connected with the surface of the rotating rod 43 and the inner wall of the mounting groove 42, providing elastic restoring force for the rotating rod 43 to rotate and wind the band 46.

[0029] Further, one end of the band 46 is fixedly connected with the surface of the rotating rod 43, ensuring the winding starting point is firm, one side of the receiving groove 41 is provided with a square groove one, the other end of the band 46 penetrates through the square groove one and is fixedly connected with the male buckle 47, and the square groove one is used for the band 46 to freely extend or retract.

[0030] Working principle: when wearing, the user first puts the headband 2 behind the head, pulls out the strap 46 from the storage groove 41 at the end of the headband 2, and buckles the male buckle 47 into the female buckle 12 on the side of the VR device body 1. When the strap 46 is pulled out, the rotating rod 43 is rotated and the coil spring 45 is energized, the rotating knob 31 on both sides is rotated, the rotating knob 31 drives the worm 32 to rotate, drives the worm gear 33 and the threaded rod 34 to rotate, and due to the action of the opposite threads on the threaded rod 34, the two sliding blocks 35 are synchronously and oppositely slid under the guidance of the sliding groove 37 until the anti-skid pads 36 on them are in contact with the limiting blocks 44, the rotating rod 43 is clamped, the length of the strap 46 is fixed to fit the back of the head, and the wearing is completed. When the device is removed, the male buckle 47 and the female buckle 12 are unbuckled, the rotating knob 31 is reversely rotated to make the sliding block 35 away from the limiting block 44, the anti-skid pad 36 is no longer in contact with the limiting block 44, so that the rotating rod 43 can be freely rotated, at this time the coil spring 45 releases the elastic force, drives the rotating rod 43 to reverse, automatically winds the strap 46 back into the storage groove 41, keeps clean, and the whole device is stably and comfortably fixed, ensuring the accuracy of the motion data collection and the comfort of the user's long-time training.

[0031] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments should, therefore, be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and therefore all changes coming within the meaning and equivalency range of the claims are intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims to the figures in which the reference signs are used.
