Problems solved by technology

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

Abstract

The electrically driven parking device for automobile includes one parking switch module comprising one casing, one switch rack, one circuit board, one infrared emitting tube and one infrared receiving tube; one parking button with one connected board with one through hole sliding between the infrared emitting tube and the infrared receiving tube; and one executing mechanism comprising one casing, one permanent magnetic DC motor, one speed reducer, one copper sleeve, one screw rod, one braking rope and one rope joint connected to the back wheel braking rope. The present invention is for the driver to control parking electrically while showing the brake state and alarming for fault prompt.

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...
