Problems solved by technology

[0003] However, due to its structural characteristics, electronic parking often only works in low-speed areas. Once a dangerous situation occurs at high speeds, you can only use hydraulic brakes or lower gears. If the hydraulic brakes also fail, it will be very dangerous. ; In addition, once an electrical failure occurs, it is often impossible to park or release the parking

Abstract

The invention provides a parking braking device which comprises a transmission mechanism and a control mechanism; the transmission mechanism is provided with a first connecting part, a second connecting part and a third connecting part; the control mechanism comprises a mechanical control part and an electronic control part; the first connecting part is used for being connected with a parking braking inhaul cable; the second connecting part is connected with the mechanical control part; the third connecting part is connected with the electronic control part, and the mechanical control part orthe electronic control part can drive the transmission mechanism to move so as to drive the parking braking inhaul cable to brake the vehicle; the device also comprises a switching mechanism which isused for controlling the electronic control part or the mechanical control part to drive the transmission mechanism. The invention further provides a parking braking system. The invention further provides a vehicle. The parking braking device, the parking braking system and the vehicle can select different parking modes to achieve braking of a vehicle and are more reliable.

Description

technical field [0001] The invention relates to the technical field of parking brakes, in particular to a parking brake device, a parking brake system and a vehicle. Background technique [0002] With the changing trend of vehicle electronization, electronic handbrakes are more and more widely used in manual transmission vehicles. According to different installation positions, electronic handbrakes can be divided into parking cable type and integrated caliper type. Both methods have their own advantages. Disadvantages, but the parking cable type is still widely used because of its simple structure and smaller changes to the original car. [0003] However, due to its structural characteristics, electronic parking often only works in low-speed areas. Once a dangerous situation occurs at high speeds, you can only use hydraulic brakes or lower gears. If the hydraulic brakes also fail, it will be very dangerous. ; In addition, in the event of an electrical failure, it often occu...
