The direction of the magnetic field generated when the electromagnet works is opposite to that of the magnetic field of the magnet.

In the initial state of the invention, the electric push rod is in a contraction state, the movable disc is positioned at the foremost end of the T-shaped sliding chute, and the two magnets on the VR glasses are respectively attracted with the electromagnet on the electric push rod. When the bicycle is used, a user pushes a bicycle into the frame, the rear wheel of the bicycle is positioned on the transmission assembly, the front wheel is clamped into the front wheel clamping groove of the rotating table, and the user rides on the bicycle; when the front wheel touches a first press switch at the front part of the front wheel clamping groove, the electric push rod works and extends to enable the VR glasses to descend; when the VR glasses descend, the electric push rod continues to extend for 4-6cm after the infrared sensor detects a signal, and then the VR glasses stop; then the first stepping motor works, and the VR glasses are slowly moved to a user through the movement of the moving disc; when the VR glasses approach the user, the user cooperatively extends the head into the lower part of the head wearing part of the VR glasses and enables the nose bridge to contact the position of the first pressure sensor; when the first pressure sensor detects a signal, the main controller controls the electromagnet on the electric push rod to work, so that the VR glasses are separated from the electric push rod, the controller controls the air pump assembly on the VR glasses to start working, the air bag is inflated, when the main controller detects that the detection value of the second pressure sensor reaches a set value, the air pump assembly is controlled to stop working, the VR glasses are fixed to the head of a user, and meanwhile, the electric push rod and the movable disc reset and the electromagnet is powered off; the rear wheel friction transmission belt enables the transmission shaft to rotate in the riding process, the riding speed is detected through the first rotary encoder on the transmission shaft, the second rotary encoder is used for the rotation angle of the front wheel of the bicycle and feeds back the rotation angle to a virtual scene, when the virtual scene is an ascending slope, the resistance is increased through the rotary damper, meanwhile, the second stepping motor is controlled to work, the upper ends of the two rotating plates rotate backwards, and due to the action of the quadrilateral mechanism, the rear end of the mounting plate descends and the front end ascends, so that the ascending slope situation is simulated; similarly, when the virtual scene displays a downhill, the second stepping motor is controlled to enable the upper ends of the two rotating plates to rotate forwards, so that the rear part of the mounting plate is lifted to simulate the downhill situation, and the sense of reality during riding is increased; when the rotating plate rotates, one side face of the rotating plate abuts against a second press switch on the bottom plate to trigger the second press switch, and the main controller controls the second stepping motor to stop working, so that the phenomenon that the lifting angle of the mounting plate is too large due to the fact that the rotating angle of the stroke rotating plate is too large is prevented; after the glasses are used, the main controller controls the electromagnetic valve to work to enable the air bag to exhaust, and a user can put the VR glasses back to the original position.

Example 2

This example is modified based on example 1 as follows: remove the dish with install the wireless module of charging of mutual matching on the VR glasses.

After the glasses are used, the VR glasses can be charged in time to prepare for next use.
