Embodiment 1

[0023] figure 1 In the shown embodiment, when there is no brake, there is no brake signal 25, the controller 26 has no control signal output, the solenoid valve 27 does not act, and the cylinder rod of the cylinder 8 is in a retracted state. Under the action of the compression spring 10, the positioning pin 2 is inserted into the positioning hole 12 on the energy recovery block 11, and the energy recovery block 11 is locked. The whole device is in a state of non-power generation. When braking, the controller 26 receives the braking signal 25, and outputs a control signal to the solenoid valve 27, and the cylinder 8 acts to drive the cylinder top plate 7 to lift the positioning pin 2 away from the energy recovery block 11. The mass eccentric energy recovery block 11 rotates around the fixed axis 5 under the action of inertia. The internal gear 15 on the energy recovery block 11 drives the central gear 17 to rotate at a high speed through the planetary gear 14, drives the gene...

Abstract

The invention relates to a vehicular braking energy recovery device which comprises a base (1), an energy recovery mechanism, a power generation mechanism, a locking mechanism and a control system. The energy recovery mechanism comprises a fixed shaft (5), a rolling bearing (3) and an energy recovery block (11); the power generation mechanism comprises a planetary gear 14, a sun gear 17 and a power generator 18; the locking mechanism comprises a cylinder 8, a cylinder top plate 7, a positioning pin 2 and a compression spring 10; and the control system comprises a speed detection sensor 20, a controller 26, an electromagnetic valve 27 or an electromagnet 21. Kinetic energy of a vehicle is partially converted into electric energy by means of inertia in braking of the vehicle. The recovered electric energy can be directly used for powering electrical appliances on the vehicle and charging vehicular batteries, and the vehicular braking energy recovery device can be widely applied to electric energy driven vehicles such as oil-fired vehicles, electric vehicles and electric bicycles. Further, the vehicular braking energy recovery device is simple in structure, small in size, energy-saving, environment-friendly and promising in application prospect.

Description

technical field [0001] The invention relates to an energy recovery device, in particular to a vehicle brake energy recovery device. Background technique [0002] People cannot live without various vehicles, such as electric vehicles driven by internal combustion engines, electric vehicles, electric bicycles, and electric tricycles. When these vehicles are running, braking is unavoidable and frequent. Vehicle braking is to use the friction between objects to convert the kinetic energy of the vehicle into heat energy, and consume energy to reduce the speed of the vehicle. As we all know, braking not only causes energy loss, but also causes wear of friction surfaces. On the other hand, due to well-known environmental protection reasons, electric energy-driven vehicles are becoming more and more popular, but one of the main reasons restricting its rapid application is the battery life. If part of the kinetic energy of the vehicle during braking can be converted into electrica...
