Jolting energy absorbing charging device for electric vehicle

Abstract

A jolting energy absorbing charging device for an electric vehicle comprises a shock absorbing hydraulic oil cylinder arranged under a chassis of the electric vehicle. One end of the shock absorbing hydraulic oil cylinder is connected with a wheel swing arm through a wheel swing arm fixing hole, and the other end of the shock absorbing hydraulic oil cylinder is connected with a vehicle frame through a vehicle frame fixing hole. The shock absorbing hydraulic oil cylinder is provided with an input one-way check valve and an output one-way check valve. The output one-way check valve is connected with an oil outlet pipe. The input one-way check valve is connected with an oil inlet pipe communicating with an input multi-cylinder distributor, and the input multi-cylinder distributor is connected with a filter net in a hydraulic oil tank. The oil outlet pipe is connected with an output multi-cylinder distributor communicating with an energy storage high-pressure oil cylinder. An energy storage piston and an energy storage spring are arranged in the energy storage high-pressure oil cylinder. An oil return pipe outside an overpressure relief port of the energy storage high-pressure oil cylinder communicates with the hydraulic oil tank. The energy storage high-pressure oil cylinder is connected with an oil inlet of a hydraulic rotating motor through an automatic pressure regulating valve. A coupling reset spring is arranged outside a center shaft of the hydraulic rotating motor and makes contact with a one-way coupling. An electric generator is driven by the one-way coupling through a reducer to generate electricity so as to charge a storage battery. An oil outlet of the hydraulic rotating motor communicates with the hydraulic oil tank.

[0002] Electric vehicles have the advantages of energy saving and environmental protection, and more and more people use them. Considerable mechanical energy converted from electrical energy is wasted when electric vehicles are idling, shifting gears, driving on bumpy roads, and braking. Part of the energy consumption is absorbed and utilized, which will improve the shock absorption performance and save energy. For example, China Patent No. 93120159.4, the patent name is the energy conversion system for automobile bumps. Gravity energy during turbulence is converted into pressure energy of high-pressure fluid, which is collected through the oil pipe, and the pressure energy of high-pressure fluid is stored by the hydraulic accumulator, and then sent to the hydraulic motor to drive a drive shaft that is directly engaged with the output shaft of the engine , the driving of the driving shaft is connected in parallel with the output driving of the engine, which is used to supplement the driving power of the engine, so as to achieve the purpose of saving energy. However, this structure has the following disadvantages: when the car is running fast, the driving shaft rotates quickly, and the driving shaft drives the hydraulic motor. It will produce no work. When the car is running slowly, the drive shaft rotates slowly, the vibration frequency is small, and the pressure in the hydraulic motor is not enough. The drive shaft drives the hydraulic motor to generate a load, and the drive shaft is meshed with the engine output shaft, which is prone to Crash the teeth, affecting the use of the system
