Description

technical field

[0001] The invention relates to an automobile parking brake device, in particular to an automobile parking brake electric booster device which has a simple structure and can provide power assistance for the driver's parking brake. Background technique

[0002] At present, what the parking brake system of existing car adopted is manual parking brake joystick. When parking brake, pull up the joystick, the joystick drives the cable system, and the cable system makes the disc (or drum) brake of the rear wheel lock the tire, thereby realizing the parking brake function. Specifically, please refer to the CN89216395 patent of China. However, the joystick of this structure has certain requirements on the driver's hand strength. If the driver's strength is relatively small (such as a female driver), it is possible that the joystick cannot be pulled in place due to insufficient strength, resulting in failure to effectively reach the parking position. The braking effe...
