[0001] The present invention relates to the field of VR somatosensory technology, and in particular to a mobile VR somatosensory device and a use method thereof. Background Art

[0002] Virtual reality or 3D technology is gradually being applied to video, film, medicine, simulation training or games. A three-dimensional virtual reality world can be created by using 3D images and posture sensors in combination with electronic computer equipment. Currently, VR helmets display virtual images and use somatosensory devices to simulate specific movements, which can bring an immersive experience of audio-visual and somatosensory levels to the experiencer. The effect is quite shocking and realistic. Somatosensory devices are machines connected to the game console. They can receive the player's movements or voice information through sensors, so as to complete the game conversion. Somatosensory devices break through the traditional game mode and allow players to throw away the game controller in their hands.

[0003] However, general VR motion sensing devices are relatively bulky. When moving the motion sensing devices, they will appear bulky and inconvenient for users to move them. At the same time, when users use them, because the pictures they see are inconsistent with the real pictures, users may collide with the protective plate on the seat, causing certain injuries to the users' bodies.

[0004] The existing patent (publication number: CN112791384B) discloses a mobile VR somatosensory device, which relates to the field of virtual reality technology, including a seat, a protective plate, a base and a safety belt.

[0024] Preferably, both ends of the safety belt are connected to the fixing seat and the reel via a clamping structure.

[0025] A method for using a mobile VR somatosensory device comprises the following steps:

[0026] S1. The user sits on the VR chair and leans back against the back support, and the back support pushes the sliding shaft to move. During this process, the tooth surface drives the vertical shaft to rotate along the tooth pattern, so that the first gear drives the armrest along the arc frame along the outer teeth to slide out to the front of the VR chair, so as to protect the user on the VR chair and prevent the user from falling off the chair due to excitement when using the VR device;

[0027] S2, when there is no user on the VR chair, the armrest is located in the arc groove, and the control rod is squeezed downward, so that the brake caliper on the slide locks each moving wheel. After the user sits on the driving armrest and moves forward, the control rod loses its restriction and is driven upward by the tension spring. At this time, the brake caliper moves upward to unlock the moving wheel;

[0028] S3. When the armrest moves forward, it rotates out from the arc frame of the right hand and docks along the arc frame of the left hand. During the docking process, the second gear contacts and is pushed by the inner ring gear, and the drive gear is used to synchronously drive the reel to rotate to pull the safety belt out of the inner groove to provide flexible protection for the user. After the armrest rotates, the elastic belt pulls the safety belt back to the inner groove.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In the present invention, the sliding shaft is pushed to move by the back support. During this process, the tooth surface drives the vertical shaft to rotate along the tooth pattern, so that the first gear drives the armrest along the outer tooth to slide out along the arc frame to the front of the VR chair, so as to protect the user on the VR chair and prevent the user from falling off the chair due to excitement when using the VR device. Compared with the existing manually inserted safety belt, the armrest provides normal hand support when standing up and sitting down. After sitting down, the back support can be used to drive the armrest ring to move to the front side of the VR chair and combine with the arc frame to form a closed annular guardrail structure. No manual operation is required by the user, which improves the convenience of use and prevents the user from being lazy and not using protective equipment.

[0031] In the present invention, the armrest is located in the arc groove and squeezes the control rod to move downward, so that the brake caliper on the slide locks the moving wheels. After the user sits on the driving armrest and moves forward, the control rod loses its restriction and is driven to move upward by the tension spring. At this time, the brake caliper moves upward to unlock the moving wheels. Compared with the existing method of starting the motor separately to control the lifting and lowering of the universal wheel, the above-mentioned control rod can cooperate with the position of the armrest to automatically control the locking status of the moving wheels according to whether there is someone on the chair. It can be locked and moved when no one is on the chair, which is convenient for users to sit on. It can be unlocked after sitting on the chair, which is convenient for the use of the VR chair and has good flexibility in use.

[0032] In the present invention, the armrest is rotated out from the arc frame of the right hand and docked along the arc frame of the left hand. During the docking process, the second gear contacts and is pushed by the inner ring gear, and the transmission gear is used to synchronously drive the reel to rotate, so as to pull the safety belt out of the inner groove, providing flexible protection for the user. Compared with the existing hand-inserted safety belt, the above-mentioned armrest and the arc frame can provide a more fitting secondary protection for the safety belt in addition to providing a rigid frame. The use of the safety belt does not require user operation, and it is automatically released and recovered, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

4. The mobile VR somatosensory device according to claim 1, characterized in that: The outer surface of the armrest (43) is fixedly provided with a soft covering surface.

5. The mobile VR somatosensory device according to claim 1, characterized in that: The shaft seat (471) and the back support (48) are connected via bolts.

6. The mobile VR somatosensory device according to claim 1, characterized in that: The surface of the handle (415) is provided with anti-slip grooves.

7. The mobile VR somatosensory device according to claim 3, characterized in that: Both ends of the safety belt (42162) are connected to the fixing seat (42163) and the reel (42164) via a snap-fit ​​structure.

8. The method for using a mobile VR somatosensory device according to claim 1, comprising the following steps: S1. The user sits on the VR chair (3) and leans back against the back support (48), and the back support (48) pushes the sliding shaft (47) to move. During this process, the tooth surface (411) drives the vertical shaft (417) to rotate along the tooth pattern (418), so that the first gear (419) drives the armrest (43) along the arc frame (44) along the outer teeth (420) to slide out to the front of the VR chair (3), so as to protect the user on the VR chair (3) and prevent the user from falling off the chair due to excitement when using the VR device; S2. When there is no user on the VR chair (3), the armrest (43) is located in the arc groove (42) and squeezes the control rod (4212) to move downward, so that the brake caliper (4215) on the slide (4214) locks each moving wheel (2). When the user sits on the driving armrest (43) and moves forward, the control rod (4212) loses its restriction and is driven upward by the tension spring (4213). At this time, the brake caliper (4215) moves upward to unlock the moving wheel (2); S3. When the armrest (43) moves forward, it rotates out from the arc frame (44) of the right hand and docks along the arc frame (44) of the left hand. During the docking process, the second gear (42167) contacts and is pushed by the inner ring gear (42169), and the transmission gear (42168) is used to synchronously drive the reel (42164) to rotate, so as to pull the safety belt (42162) out of the inner groove (42161) to provide flexible protection for the user. After the armrest (43) rotates, the elastic belt (42165) pulls the safety belt (42162) back to the inner groove (42161).
