DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0021] As shown in Figure 1 - Figure 8 A VR lens protection device, comprising: An attitude detection module: responsible for real-time monitoring of the motion state and attitude change of the VR device body 1, and identifying the falling event; The posture adjusting module is responsible for quickly adjusting the posture of the VR device body 1 when it is detected that the VR device body 1 is in a free-fall state, to ensure that the bottom of the VR device body 1 faces downward; The protection triggering module is responsible for triggering the buffer mechanism for buffering protection of the VR device body 1 when the VR device body 1 is about to touch the ground; The VR device body 1 is symmetrically provided with a VR lens body 3 on one side, and a protective pad 2 is fixedly connected to the side of the VR device body 1 away from the VR lens body 3. The protection triggering module is arranged at the lower part of the protective pad 2. The buffer mechanism comprises a groove 7 opened in the interior of the protective pad 2, a fixed sleeve 14 fixedly connected in the interior of the groove 7, a first sliding frame 16 slidingly connected in the interior of the fixed sleeve 14, a buffer pad 15 fixedly connected to the lower part of the first sliding frame 16 for buffering, a second sliding frame 20 slidingly connected in the interior of the fixed sleeve 14, a first rack 22 fixedly connected to one side of the second sliding frame 20, a first gear 17 meshingly connected to the first rack 22, a second rotating shaft 19 fixedly connected to the first gear 17, a second gear 24 fixedly connected to the second rotating shaft 19, a second rack 23 meshingly connected to the side of the second gear 24 close to the first rack 22, and the second rack 23 is fixedly connected to the first sliding frame 16. A buffer spring 21 is fixedly connected to the lower part of the second sliding frame 20 for damping, and the lower part of the buffer spring 21 is fixedly connected to the first sliding frame 16.

[0022] The working principle of the VR lens protection device is that when the posture detection module detects that the VR device body 1 is in free fall, the lower part of the protective pad 2 fixedly connected to one side of the VR device body 1 will first contact the ground under the cooperation of the posture detection module and the posture adjusting module, and the buffer mechanism will be triggered before contact, so that the buffer mechanism extends outside the protective pad 2 to facilitate buffering when contacting the ground; When the protection triggering module opens the buffer mechanism, the buffer pad 15 will drive the first sliding frame 16 to extend outside the protective pad 2 under the elastic action of the buffer spring 21 and the gravity action of the buffer pad 15. When the first sliding frame 16 moves downward, the fixedly connected second rack 23 will move, the downward movement of the second rack 23 will cause the meshingly connected second gear 24 to rotate, the rotation of the second gear 24 will cause the fixedly connected second rotating shaft 19 to rotate, and the second rotating shaft 19 will cause the fixedly connected first gear 17 to rotate, and the rotation direction of the first gear 17 is the same as that of the second gear 24; When the first gear 17 rotates, the second sliding frame 20 is also driven to slide downward through the meshing connection of the second gear 24, and the second sliding frame 20 is fixedly connected with the first sliding frame 16 and has the buffer spring 21, so that when the VR device main body 1 accidentally falls, the buffer pad 15 is first in contact with the ground to preliminarily buffer, and the buffer pad 15 in contact with the ground compresses the buffer spring 21 upward, so that the damping effect is achieved under the action of the buffer spring 21, that is, the damage to the VR lens body 3 caused by accidental falling of the VR device main body 1 can be reduced.

[0023] In one embodiment, for the above-mentioned posture detection module, the posture detection module and the posture adjustment module are arranged in the interior of the VR device main body 1, the second rotating shaft 19 is rotatably connected with the fixed sleeve 14, and the fixed sleeve 14 is fixedly connected with the limiting rod 18 for preventing the first sliding frame 16 and the second sliding frame 20 from falling off.

[0025] In one embodiment, for the above-mentioned buffer mechanism, the buffer mechanism is provided in plurality and is uniformly distributed in the interior of the protective pad 2, and parts and mounting modes thereof are same.

[0026] The working principle of the VR lens protection device is that the limiting rod 18 fixedly connected in the interior of the fixed sleeve 14 is convenient for limiting when the first sliding frame 16 and the second sliding frame 20 fall, so as to prevent the first sliding frame 16 and the second sliding frame 20 from falling off, and the first fixed column 25 fixedly connected to the lower part of the second sliding frame 20 and the second fixed column 26 fixedly connected to the side of the first sliding frame 16 close to the second sliding frame 20 limit the buffer spring 21, so as to prevent the buffer spring 21 from being dislocated when being stretched and retracted.

[0027] In one embodiment, for the above-mentioned VR device main body 1, the fixed band 4 for fixing the VR device main body 1 is arranged on the side of the VR device main body 1 away from the protective pad 2, the nose clamping device 5 is arranged on the lower part of the VR device main body 1, and the adjuster 6 for adjusting the tightness of the fixed band 4 is arranged on the upper part of the VR device main body 1.

[0028] In one embodiment, for the above protective pad 2, the lower part of the protective pad 2 is provided with a shielding mechanism for preventing the buffer mechanism from being accidentally opened during normal use of the VR device main body 1, and the shielding mechanism comprises a first motor 8 fixedly installed on one side of the protective pad 2.

[0029] In one embodiment, for the above first motor 8, the output end of the first motor 8 is provided with a first rotating shaft 9, and one side of the first rotating shaft 9 is fixedly connected with a pressing plate 10 for preventing the buffer pad 15 from falling off, and the inside of the pressing plate 10 is provided with a limiting groove 11.

[0031] In one embodiment, for the above shielding mechanism, the shielding mechanism is provided in multiple, uniformly distributed on the lower part of the buffer mechanism, and the parts and installation methods are the same.

[0032] The working principle of the VR lens protection device proposed in the application is that when the VR device main body 1 is normally used, the shielding mechanism will shield the pressing plate 10 from the buffer mechanism, preventing the buffer mechanism from being accidentally opened, and when it is detected that the buffer mechanism needs to be opened, the limiting plate 13 is rotated to a position parallel to the limiting groove 11 at this time, and the limiting groove 11 can pass through the limiting plate 13 at this time, and the first motor 8 is started at this time, so that the first rotating shaft 9 provided at the output end of the first motor 8 rotates, and the rotating of the first rotating shaft 9 will make the fixedly connected pressing plate 10 overturn, and the overturning of the pressing plate 10 will make the limiting groove 11 pass through the limiting plate 13 parallel to the limiting groove 11, that is, the pressing plate 10 can be opened, which is convenient for the buffer mechanism to extend outside the protective pad 2.

The posture adjustment module accurately executes the posture adjustment task.
