Abstract

A parking brake for open type motor vehicles comprises a pulse switch mechanism, a follow-up pedal mechanism, a shifting fork mechanism and a magnetically-controlled pawl mechanism, wherein the follow-up pedal mechanism is combined with shifting fork mechanism. The pulse switch mechanism comprises a pulse switch key handle, a tension spring, a swing arm, keys and a connector bar, wherein the tension spring, the swing arm, the keys and the connector bar are arranged in a switch shell. The follow-up pedal mechanism comprises a parking brake pedal and a pedal rod, the upper end of the pedal rod is provided with a shifting form with a groove, and the switch key handle of the pulse switch mechanism is inserted in the groove of the shifting fork. The magnetically-controlled pawl mechanism comprises an electromagnet and a pawl, and the electromagnet is respectively connected with a motor vehicle key switch, a thyristor, a state switch and a pulse switch. The parking brake is simple in structure, electronic devices are added based on mechanical braking, an original mechanical structure is simplified, electromechanical integration is realized, the size of the brake is reduced, cost is reduced, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to a brake device, in particular to a parking brake for an open motor vehicle. Background technique [0002] The parking brake is an indispensable parking safety device for motor vehicles. Before the driver leaves the vehicle, the parking brake must be tightened and the door locked to prevent the car from slipping or being moved. For non-enclosed motor vehicles, such as: motor tricycles, sightseeing buses in scenic spots, service vehicles in the jurisdiction, field vehicles, open sanitation vehicles, open patrol vehicles, etc. Due to the open or semi-open design of this type of motor vehicle, when the driver stops and pulls on the handbrake to apply the parking brake, and after leaving the vehicle, once the non-driver releases the parking brake of the vehicle, it will cause an accident. Hidden danger. Contents of the invention [0003] The present invention aims at the defects existing in the background technology, and provide...
