Problems solved by technology

[0007] The purpose of the present invention is to provide a parking guarantee device after the EPB failure of the vehicle, which solves the problem of the existing EPB (electronic parking) when the vehicle power fails (including the vehicle high-voltage battery and storage battery) or the EPB ECU and related components appear. When a fault is reported, the car cannot be parked on the ramp, and the safety of the driver cannot be guaranteed

Embodiment 1

[0030] Such as figure 1 As shown, the parking protection device provided by the present invention after a kind of vehicle EPB failure includes: an energy storage device 1, which is used to store and adjust the size of the braking force; a second brake pipeline 2, the second brake One end of the pipeline is connected to the energy storage device, and the other end is connected to the caliper 3 . The vehicle parking protection device after EPB failure also includes a first brake pipeline 4 and a brake master cylinder 5, the brake master cylinder is used to provide braking force; the brake master cylinder is located at the first brake end of the pipe. One end of the first brake pipeline is connected to the brake master cylinder, and the other end is connected to the energy storage device; the middle part of the first brake pipeline is also connected to the caliper on the side, which is used to transmit the braking force to the caliper. The first brake pipeline and the second br...

Embodiment 2

[0035] The invention provides a parking protection device for a vehicle after EPB fails, comprising: an energy storage device for storing and adjusting the braking force; a second brake pipeline, one end of which is connected to the storage battery The other end is connected to the caliper.

Abstract

The invention provides a device for ensuring parking after the failure of a vehicle EPB. The device comprises an energy storage unit used for storing and regulating braking force, and a second brakingline with one end connected with the energy storage unit and the other end connected with calipers. According to the device, the second braking line and the energy storage unit are additionally arranged on the basis of a traditional EPB system, and it can be guranateed that parking is realized under a power failure.

Description

technical field [0001] The invention relates to the field of spare parts of new energy automobiles, in particular to a parking protection device for vehicles after EPB failure. Background technique [0002] Electronic Parking EPB (Electrical Parking Brake) refers to the technology that realizes parking brake by electronic control. Electronic handbrake is a technology that realizes parking brake by electronic control. [0003] Electronic Parking Brake (EPB: Electrical Park Brake) refers to a technology that integrates temporary braking during driving and long-term braking after parking, and realizes parking braking by electronic control. [0004] Electronic handbrake is a technology that realizes parking brake by electronic control. Its working principle is the same as that of the mechanical hand brake, both of which use the cable to tighten the brake shoe of the rear wheel for braking. The other is to use electromechanical calipers, which control the parking brake through...
