The brake release operation is very simple.

The technical solution of the present invention is: an inductive braking release device for baby carriages, which includes a frame and a brake mechanism between the rear wheel seat and the rear wheel, and the brake mechanism includes a brake mechanism arranged on the rear wheel seat. And the brake lever that can move laterally relative to it, the brake disc that is fixed on the rear wheel, a compression spring is provided between the brake lever and the rear wheel seat, and the push handle of the vehicle frame is provided with a signal transmission unit. Wrist strap, one end of the wrist strap is connected and fixed with the push handle, and the other end has an induction bracelet for the wrist to set and is used to prompt the signal transmitting unit to send a signal. The rear wheel seat is provided with a signal receiving unit, and the signal The transmitting unit and the signal receiving unit are wirelessly connected, the frame is provided with a power supply unit for supplying power to the signal transmitting unit and the signal receiving unit, the brake lever is a metal suction part, and the brake disc is at least partly Electromagnet, when the induction bracelet is empty, the electromagnet is in the energized state and has magnetism, and the brake lever protrudes outwards under the action of the magnetic force and snaps into the slot of the brake disc. At this time, the rear wheel cannot rotate and is in the braking state. When the pusher's hand penetrates the induction wristband, the induction bracelet prompts the signal transmitting unit to send out a signal, and the signal receiving unit cuts off the electromagnet after receiving the corresponding signal, the gravitational force between the brake disc and the brake lever disappears, and the brake lever is under pressure. Under the action of the spring, reset and move inward to break away from the brake disc, at this time, the rear wheel can rotate relative to the vehicle frame to realize releasing the brake.

Further, a rear wheel shaft is passed between the two rear wheel seats, and the power supply unit is arranged on the rear wheel shaft. The signal receiving unit is arranged on the inner side of the rear wheel seat.

The utility model has the advantages that: the utility model is provided with a wrist strap on the push handle, and the outer end of the wrist strap is provided with an induction bracelet. A signal is sent out, and the electromagnet is powered off through the signal receiving unit, and then the brake is released to realize normal walking. When the pusher's hand leaves the induction bracelet, the signal disappears, and the electromagnet returns to the energized state and uses its own magnetic adsorption metal accessories. The suction piece prevents the rear wheels from turning and realizes automatic braking, which greatly improves the safety performance of the vehicle.

Detailed ways

Embodiment: as shown in Fig. 1 to Fig. 4, a kind of inductive brake releasing device of stroller, it comprises vehicle frame 1 and the brake mechanism between the rear wheel seat 2 and rear wheel 3 of vehicle frame 1, 4, so The brake mechanism 4 includes a brake lever 41 which is arranged on the rear wheel base 2 and can move laterally relative to it, and a brake disc 42 which is fixed on the rear wheel 3 . Spring 43, the push handle 5 of the vehicle frame 1 is provided with a wrist strap 7 with a signal transmitting unit, one end of the wrist strap 7 is connected and fixed with the push handle, and the other end is provided with a wrist strap for urging the signal transmitting unit An induction bracelet 6 for sending signals, the rear wheel base 2 is provided with a signal receiving unit 9, the signal transmitting unit is connected with the signal receiving unit 9 for wireless signals, and the vehicle frame is provided with a signal transmitting unit And the power supply unit 8 powered by the signal receiving unit, the brake lever 41 is a metal matching suction part, and the brake disc 42 is at least partly an electromagnet. When the induction bracelet 6 is empty, the electromagnet is in a energized state and has magnetism. The rod is stretched out by the magnetic force and is stuck in the draw-in groove of the brake disc 42. At this time, the rear wheel 3 cannot rotate and is in a braking state. When the pusher's hand penetrates the induction bracelet 6, the induction bracelet prompts the signal to be emitted The unit sends out a signal, and the signal receiving unit de-energizes the electromagnet after receiving the corresponding signal, the gravitational force between the brake disc 42 and the brake lever 41 disappears, and the brake lever 41 resets and moves inwardly from the brake disc 42 under the action of the compression spring.
