DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a VR head display device, including a VR head display body 1, and an elastic strap 2, both ends of the elastic strap 2 are connected to the VR head display body 1, an auxiliary belt 3 is provided on the upper wall of the VR head display body 1, a bracket 4 is provided at the center of the side wall of the elastic strap 2, one end of the auxiliary belt 3 is penetrated through the bracket 4, a toothed belt 5 is provided on the upper wall of the auxiliary belt 3 along the length direction, a positioning component for fixing the auxiliary belt 3 is provided on the bracket 4, and dustproof components are provided on the upper and lower sides of the VR head display body 1.

[0021] By adopting the above technical solution, when wearing, the VR headset body is fixed on the user's head by an elastic strap, and then the use length of the auxiliary strap is adjusted by the positioning component according to the size of the head, so that the auxiliary strap is close to the top of the user's head, thereby preventing the VR headset body from sliding down and improving the wearing stability.

[0022] This embodiment is further configured as follows: the positioning assembly includes a through hole opened on the bracket 4, a pull rod 6 is arranged in the through hole, a handle 7 is installed at one end of the pull rod 6, and a positioning plate 8 is installed at the other end, and the side wall of the positioning plate 8 is provided with positioning teeth 9 engaged with the toothed belt 5, and a pair of sliding grooves 10 are provided on the inner walls on both sides of the bracket 4, a slider 11 is provided in the sliding groove 10, and a spring 12 is provided between the slider 11 and the inner wall of the sliding groove 10.

[0023] By adopting the above technical solution, the handle is pulled to make the pull rod drive the positioning plate to move outward, and the slider slides in the slide groove to compress the spring. At this time, the positioning teeth are separated from the toothed belt, and the auxiliary belt can be pulled to adjust its use length. After adjusting to the appropriate length, the handle is released, and the spring drives the positioning plate to reset, so that the positioning teeth and the toothed belt are re-engaged, thereby completing the fixation of the auxiliary belt.

[0024] This embodiment is further configured such that the dustproof component includes a pair of connecting rods 13 hinged on both sides of the VR head display body 1, a sleeve 14 is slidably sleeved on the upper end of the connecting rod 13, a tension spring 15 is installed between the inner wall of the sleeve 14 and the connecting rod 13, a pair of connecting members 16 are fixedly installed on the upper ends of the pair of sleeves 14, and a dust shield 17 is installed between the pair of connecting members 16.

[0025] By adopting the above technical solution, when the device is idle, the dust shield plates located on the upper and lower sides of the VR head display device can be rotated 90° to both sides respectively, so that the front and rear sides of the VR head display device can be dust-proofed. When adjusting, the dust shield plate is pulled to separate it from the VR head display body. At this time, the sleeve slides outward on the connecting rod to stretch the tension spring. After the dust shield plate is rotated 90°, the dust shield plate is released, and the tension spring provides tension for the sleeve, so that the sleeve drives the dust shield plate to move in the direction of the VR head display body, so that the dust shield plate fits with the VR head display device body to achieve dust prevention.

[0026] This embodiment is further configured such that a sponge pad 18 is provided on the side wall of the dust shield 17 close to the VR head display body 1.

[0027] By adopting the above technical solution, the provision of the sponge pad can avoid the problem of damage to the VR headset body caused by the hard contact between the dust shield and the VR headset device.

[0028] The present embodiment is further configured such that a slot 19 for the elastic band 2 to pass through is provided on the dust shield 17 located at the lower side.

[0029] By adopting the above technical solution, the dust shield located at the bottom is rotated toward the rear of the VR head display body and blocks it. The setting of the groove can avoid movement interference between the dust shield and the strap.

[0030] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0031] Embodiment: When wearing, the VR head display body 1 is fixed on the user's head through the elastic strap 2, and the handle 7 is pulled to make the pull rod 6 drive the positioning plate 8 to move outward, and the slider 11 slides in the slide groove 10 to compress the spring 12. At this time, the positioning teeth 9 are separated from the toothed belt 5, and the auxiliary belt 3 can be pulled to adjust its use length. After adjusting to a suitable length, the handle 7 is released, and the spring 12 drives the positioning plate 8 to reset, so that the positioning teeth 9 and the toothed belt 5 are re-engaged, and the auxiliary belt 3 is fixed. At this time, the auxiliary belt 3 is attached to the top of the user's head, thereby preventing the VR head display body 1 from sliding down and improving the wearing stability;

[0032] When idle, the dust shield 17 located on the upper and lower sides of the VR head display device can be rotated 90° to both sides respectively, so that the front and rear sides of the VR head display device are dust-proof. When adjusting, the dust shield 17 is pulled to separate it from the VR head display body 1. At this time, the sleeve 14 slides outward on the connecting rod 13 to stretch the tension spring 15. After the dust shield 17 is rotated 90°, the dust shield 17 is released, and the tension spring 15 provides tension for the sleeve 14, so that the sleeve 14 drives the dust shield 17 to move in the direction of the VR head display body 1, so that the dust shield 17 fits with the VR head display device body to achieve dust prevention.
