When the lock core 11 is adapted to rotate, it drives the slide 13 to slide up and down.

[0045] like Figures 1 to 6 As shown, the lock structure suitable for the front wheel, rear wheel and electric door has a lock cylinder 11. After the lock cylinder 11 is removed from the key, the slide 13 is located in the lock box 14, the rear wheel cable is not tightened, and the locking block on the rear wheel is pushed into the slot of the rear wheel turntable by the action of the spring, the rear wheel is locked, the inclined platform of the pull rod 5 is located below the through hole of the outer tube 4, the middle tube 1 and the inner tube 19, the front wheel frame is locked to the vehicle body, the movable contact piece 28 is not aligned with the two electrodes 25 and connected, and the two electric door wires are disconnected. Locked state; and when the lock cylinder 11 is turned by the key, the slide plate 13 slides upward, the rear wheel cable is tightened, the locking block on the rear wheel disengages from the slot of the rear wheel turntable, and the rear wheel rotates freely. The inclined platform of the pull rod 5 rises to the through hole of the outer tube 4, the middle tube 1 and the inner tube 19, pushing the inner end of the locking block 21 to slide to the gap between the outer tube 4 and the middle tube 1, the front wheel frame rotates freely, the movable contact 28 is aligned and connected with the two electrodes 25, and the two electric switch wires are connected to the open state.

[0046] The main working principle of the lock structure applicable to the front wheel, rear wheel and electric door described in this application is briefly described as follows: Figures 1 to 3 As shown, when the lock structure for the front wheels, rear wheels, and ignition switch is in the locked state, the slide plate 13 is located near the lower end of the lock box 14. The two electrodes 25 on the electrode holder 26 are not aligned with the movable contact piece 28, that is, the two ignition wires are disconnected, and the vehicle cannot be started. The first pressure plate 15 on the slide plate 13 is also in the middle position of the lock box 14. The rear wheel cable is in a natural state. Under the action of the spring force, the locking block on the rear wheel is pushed into the slot of the rear wheel turntable, and the rear wheel is locked, that is, the rear wheel cannot rotate. Under the action of the first elastic member 23, the locking block 21 is pushed into the through-hole of the inner tube 19 and the middle tube 1, and the direction of the front wheel is also locked, preventing free rotation.

[0047] like Figures 4 to 6As shown, when the lock structure for the front and rear wheels, as well as the ignition switch, is in the unlocked state, the lock cylinder 11 rotates. The first pin 10 pushes the slide 13 upward, causing it to extend out of the lock box 14 or simply slide upward, remaining within the lock box 14. The two electrodes 25 on the electrode holder 26 align with the movable contact 28, connecting the two ignition wires and allowing the vehicle to start. The first pressure plate 15 on the slide 13 is also positioned near the upper end of the lock box 14. The rear wheel cable is tightened, pulling the locking block on the rear wheel away from the slot in the rear wheel turntable. The rear wheels are unlocked, allowing them to rotate freely. The pull rod 5 moves upward, and the ramp on the pull rod 5 lifts the locking block 21 to the interface of the outer circumference of the middle tube 1 (or outside the interface, meaning the inner end of the locking block 21 is located in the gap between the outer tube 4 and the middle tube 1). The outer tube 4 separates from the inner tube 19 and the middle tube 1, unlocking the front wheel and allowing it to rotate freely.

[0048] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
