Abstract
A power-generation shock absorber belongs to an electromechanical product and is mainly applied to vehicles such as automobiles, tractors, etc. Aiming to the problems that the existing shock absorbers can not generate power, and part of the shock absorbers are not provided with damping force adjustment and over-voltage protection circuits, the utility model discloses the power-generation shock absorber consisting of a semi-permanent magnetic generator, a variable-speed mechanism, a reverse mechanism, a damping force adjusting circuit and an over-voltage protection circuit. The generator is fixed on the vehicle body; a gear rack is connected with an axle through a hinge; and the gear rack is meshed with the drive gear of the generator in the shock absorber. When the vehicle body vibrates up and down, the gear rack drives the drive gear to rotate, and the drive gear leads the reverse mechanism and the variable-speed mechanism to drive the generator to generate power. The power-generation shock absorber can convert mechanical energy generated by up-down vibration of the vehicle body along with the road conditions into electrical energy, so as to provide power for power-consumption equipment and battery jars together with a vehicle-mounted generator, thereby reducing the load of an engine, saving fuel, and achieving the effects of energy conservation and emission reduction.

Summary of the invention
In order to solve the above defective that prior art exists, the utility model provides a kind of electricity generation shock absorber, and his compact conformation rationally and damping force adjustment and over-pressure safety device arranged.
The technical scheme that its technical problem that solves the utility model adopts is: electricity generation shock absorber adjusts circuit by half permanent magnet generator, gear, changement, damping force and overvoltage crowbar is formed.As shown in Figure 1, electricity generation shock absorber is fixed on the car body, and tooth bar links to each other with vehicle bridge by hinge, the driven wheel engagement of tooth bar and electricity generation shock absorber.When the car body vertical tremor, the forward and reverse rotation of rack drives driven wheel.Electricity generation shock absorber mainly is made up of changement, gear and generator.Changement is made up of four angular wheels and two one-way clutch; Gear is a planetary gears; Generator is half magneto-electric generator.So-called half permanent magnet generator is to install permanent magnet additional on the rotor of electric excitation generator, the generator that the excitation of generator is finished jointly by permanent magnet and excitation winding.Changement becomes forward and reverse rotation of driving wheel by one-way clutch and bevel gear the one-directional rotation of power shaft, quicken to make output speed reach the rotating speed requirement of generator through epicyclic transmission at last, drive the generating of half permanent magnet generator by output shaft, give power consumption equipment and storage battery power supply.
As shown in Figure 3, the damping force control circuit is by IC1 (555), two capacitor C 1, C2, and two resistance R 1, R2, R5, two diode D1, D2, triode T1, T2, amplifier IC2 and variable resistor R3 or computer are formed.Thereby can control the damping force of electricity generation shock absorber according to the electric current on conditions such as the road conditions control excitation winding by artificial or computer.
As shown in Figure 4, overvoltage crowbar is made up of testing circuit R6R7, voltage stabilizing didoe, Darlington transistor, relay and resistance.When power consumption equipment more for a long time, electricity generation shock absorber with engine with generator power; When power consumption equipment more after a little while; along with the rising generator that engine is with of voltage is deactivated gradually; independently-powered by electricity generation shock absorber, if the energy output of electricity generation shock absorber greater than power consumption, voltage continue to raise; voltage stabilizing didoe conducting this moment; electric current by the base stage of voltage stabilizing didoe, current-limiting resistance, Darlington transistor, emitter to ground, Darlington transistor conducting, relay closes; electric current arrives ground through high-power resistance R9 and relay, plays the effect of overvoltage protection.
The beneficial effects of the utility model are, the jolt mechanical energy of vibrations of vehicles such as automobile and tractor is converted into electric energy and is used, and play the effect of energy-saving and emission-reduction, and its compact conformation is reasonable, and can realize damping force adjustment and over-voltage protecting function.
