The non-return wire spring now accumulates a torsion force. When the pedal is stepped on, the other end of the check wire is matched with the check seat, and the other end of the check wire can move along the track structure on the check seat.

The pedal telescopic spare wheel device applied to the personal electric vehicle for preventing rollover is applied to a novel mechanical device on the personal electric vehicle for replacing the walking so as to realize the function of preventing rollover of the electric vehicle in the running process. The safety and reliability of the bicycle are improved to the maximum extent, so that the bicycle can be easily used for traveling without worry.

Specifically, the shell comprises a baffle and a shell frame, and the baffle is connected with the shell frame through a rotary hinge.

Further, a convex ball is arranged on the supporting plate. The rotary hinge is a spring hinge capable of realizing automatic rebound.

The working principle of the pedal telescopic spare wheel device applied to the personal electric vehicle rollover prevention of the embodiment of the utility model is as follows:

when the base is in an unoperated state, the base is connected with the supporting plate through the collision bead, the collision bead is fixed on the base, a groove matched with the collision bead is formed in the supporting plate, and the base clamps the supporting plate through the collision bead under the condition of no external force.

When the foot pedal is depressed for the first time, a state diagram of the motion of the self-locking switch mechanism during the extension of the spare wheel is shown in fig. 11a to 11 d. The foot pedal is stepped on to enable the foot pedal to move around the shaft of the hinge through the rotary hinge. Because the sector gear and the central gear which are welded under the foot pedal are meshed with each other. The central shaft is fixedly connected with the base, the central gear and the spring clamping seat are respectively and fixedly connected with the supporting plate, the central gear and the spring clamping seat can rotate relative to the central shaft, one end of the spring is connected with the spring clamping seat, the other end of the spring is connected with the central shaft, when the pedal moves downwards, the sector gear is pushed to move downwards, the sector gear is meshed with the central gear, the sector gear drives the central gear to rotate, the central gear and the spring clamping seat can respectively rotate around the central shaft, the central gear is fixedly connected with the supporting plate, the central gear drives the supporting plate to rotate, meanwhile, the spring is twisted, and when the supporting plate rotates downwards, the energy is accumulated by the rotary spring; when the support plate rotates 90 degrees and stands downwards, the small wheel hangs down to be about 2 cm away from the ground. The working process of the self-locking switch mechanism is as follows: the check wire is arranged on the base and can swing up and down at a certain angle, and meanwhile, the check wire spring can enable the check wire to be kept at a balance position under the condition of no stress. When the support plate moves downwards with the check seat, namely, approaches the check wire, the other end of the check wire is jacked upwards, then continuously moves into a gap in the middle of the check seat, and the check wire returns to the middle position when the check wire spring is stopped in the gap. At this time, the driver releases the pedal, the support plate can reversely move under the action of the reverse force of the central shaft spring, namely, the upward movement rebounds, and the extending section of the check wire clamps the V-shaped recess in the check seat, so that the support plate is prevented from continuously rebounding. The state of fig. 11d is now the final state when the foot pedal is first depressed, i.e. the support means is perpendicular to the ground. Wherein when the supporting plate is unscrewed, namely moves downwards, the convex ball is arranged below the supporting plate to push the bottom plate of the shell away.

When the pedal is depressed a second time, a state diagram of the motion of the self-locking switch mechanism during retraction of the spare wheel is shown in fig. 12a to 12 c. The pedal continues to push the sector gear downward, and the support plate can continue to move forward and cross the vertical line at a certain angle. At this time, the other end of the check thread slides downwards under the action of the check seat protrusion to push out the middle V groove. Then the driver's foot is released, and the whole support plate is driven to rebound upwards due to the rotation of the rotary spring. The check thread is pushed downward and continues to rotate until the check thread slides back again to the equilibrium position. The support plate releases the self-locking. The back plate and the foot pedal then continue to rotate due to the force of the central shaft spring, and the bottom plate of the housing portion also begins to close due to the force of the swivel hinge. And finally, returning to the initial position, and completing one action till the initial position is completely reached. When the whole vehicle turns without decelerating, centrifugal force causes the whole vehicle to incline to one side of the turn by about 8 degrees, and the small wheels land to increase a supporting point, so that the side turning of the whole vehicle is avoided.

The pedal telescopic spare wheel device for preventing the personal electric vehicle from rollover, disclosed by the utility model, has the advantages that the potential safety hazard of rollover during turning is avoided, the use is safer, the travel driving safety is improved, and the operation is simple, convenient and quick.
