Electric parking device for car

Abstract

An electric parking device for automobiles, the technical points are: the main support of the switch is connected in the switch housing of the parking switch assembly, the main support is fixedly connected to the circuit board, and the infrared emitting tube and the receiving device are arranged on the circuit board according to symmetrical positions. The parking switch button is slidably installed on the main bracket, and the inner end of the parking switch button is connected with an orifice plate with an infrared through hole, and the orifice plate slides between the infrared emitting tube and the infrared receiving tube; The permanent magnet direct current motor is connected to the reducer by the transmission of the permanent magnet direct current motor, and its output end drives the inner threaded copper sleeve, the threaded rod, the brake cable and the cable joint connected with the brake cable of the rear wheel of the motor vehicle. The present invention controls the switch stroke by the driver, collects its state information through far-infrared emission and reception, judges through comprehensive logic, and then controls the DC motor and pulls the parking cable after being decelerated by the deceleration device, so as to realize the electric control of the car parking , and display the system's braking, non-braking and fault information alarm prompts.

Description

technical field [0001] The invention belongs to the technical field of brake systems of motor vehicles, in particular to an electric parking device for automobiles. Background technique [0002] As everyone knows, motor vehicle adopts foot brake to brake during operation, and then adopts hand brake to brake when parking. At present, the traditional handbrakes are purely mechanical, and long-term use will reduce their effectiveness. The handbrake is connected to the rear brake shoe by a steel wire cable to brake the car. Long-term use of the handbrake will cause plastic deformation of the steel wire. Due to this deformation It is non-recoverable, so long-term use will reduce the effectiveness and the stroke of the handbrake will increase. In addition, there is a return spring used in conjunction with the handbrake. When the handbrake is pulled up, the spring is stretched; when the handbrake is released, the spring returns to its original length. Therefore, when the handbrak...
