Semi-decoupled braking device for regenerative braking of new energy vehicles

Abstract

The invention discloses a semi-decoupling braking device for regenerative braking of new energy vehicles, comprising a fixed plate and a pedal body installed on the new energy vehicle, the pedal body is provided with a pedal connecting rod, and the fixed plate The first spring is provided with a plurality of first springs, and the ends of the plurality of first springs are provided with movable plates, and the movable plate is provided with a first rack, and the fixed plate and the movable plate An energy regeneration mechanism is arranged between them, and the first rack is connected to the energy regeneration mechanism. This semi-decoupling braking device is used for regenerative braking of new energy vehicles, so as to be different from the prior art, so that through the pedal The extrusion of the movable plate by the displacement of the connecting rod drives the first rack to drive the energy regeneration mechanism to realize the power storage work during the braking process. Through the functional top block, the brake assembly is driven to shift, which can realize the front wheel of the new energy vehicle. Brake, and when the pedal connecting rod shifts, drive the transmission mechanism to work through the ejector rod to realize the function of the ejector block rotation.

Description

technical field [0001] The invention relates to the technical field of braking devices for new energy vehicles, in particular to a semi-decoupling braking device for regenerative braking of new energy vehicles. Background technique [0002] With the rising awareness of environmental protection, low-pollution hybrid and pure electric energy-saving vehicles have gradually become popular among consumers. In order to fully utilize the kinetic energy of such energy-saving vehicles during deceleration, regenerative braking The mechanism was developed. Regenerative braking, also known as feedback braking, is a braking technology used on electric vehicles, which converts and stores the kinetic energy of the vehicle during braking; rather than turning it into useless heat, regeneration Braking Switches the motor to alternator operation under braking conditions, uses the inertia of the vehicle to drive the motor rotor to rotate to generate a reverse torque, converts a part of the kine...

Problems solved by technology

[0006] However, we found in actual use that when braking with a small intensity, the system replaces the original hydraulic system braking through the cooperation of the pedal travel sensor and the drive motor to reduce heat energy consumption during braking. However, The existing pedal stroke sensor and the drive motor are transmitted through signals, which is very easy to affect the braking effect during low-intensity braking due to circuit problems or external signal interference, resulting in the failure of braking for new energy vehicles, and vehicle scratches and other traffic accidents, for this reason, we propose a semi-decoupled braking device for regenerative braking of new energy vehicles
