Baby carriage brake system

Abstract

The invention discloses a brake system of a stroller. The brake system is arranged on a frame. Brake mechanisms are respectively arranged between rear wheels and rear wheel seats on two sides of the frame, signal transmitting units and a switch button are arranged on a push handle of the frame, the switch button is used for driving the signal transmitting units to transmit signals, signal receiving units are arranged on the brake mechanisms and are in wireless signal connection with the signal transmitting units, power units which are used for powering the signal transmitting units and the signal receiving units are arranged on the frame, the brake mechanisms comprise first electromagnets or first metal suction components and second metal suction components or second electromagnets, the first electromagnets or first metal suction components are arranged on the rear wheels, and the second metal suction components or second electromagnets are arranged on the frame. The brake system has the advantages that a pushing person can hold the push handle with the hands to touch the switch button when pushing the stroller, accordingly, the signals can be transmitted by the signal transmitting units, the electromagnets can be powered off by the aid of the signal receiving units, brake can be relieved, and the stroller can run normally; the signals disappear when the hands of the pushing person leave the push handle, power-on states of the electromagnets are recovered, the metal suction components can be sucked by the aid of magnetism of the electromagnets, accordingly, the rear wheels cannot rotate, automatic brake effects can be realized, and the safety performance of the integral stroller can be greatly improved.

Description

technical field [0001] The invention relates to a brake system of a baby carriage. Background technique [0002] Existing baby carriages are generally all provided with braking mechanisms at the rear wheels in order to ensure driving safety. At present, the brake mechanism usually includes a brake lever and a brake disc with multiple brake grooves. When braking, the brake lever can be inserted into the brake groove to achieve braking. However, when the brake mechanism needs to be released, the brake lever is easily stuck in the brake groove and is not easy Unlocking, in addition the existing unlocking parts all need to be operated by foot, and the unlocking operation is inconvenient during implementation. Contents of the invention [0003] The object of the present invention is to provide a braking system for a stroller, which can realize automatic braking as long as the hand leaves the push handle during the promotion process, which greatly improves the safety performanc...
