Electricity generating device by applying vehicle weight
First Claim
1. An electricity generating device by applying vehicle weight, utilizing a driver with restoring force, said driver comprising a pressure receiver and a restoring weight element hinged together onto a mandrel and forming a predetermined angle therebetween, wherein said angle formed between said pressure receiver and said restoring element is designed to have a value according to predetermined angular swinging speed of said driver, and said driver is able to provide a continuous unidirectional rotating torque to drive a generator to output electrical energy when being exerted a vehicle weight, andwherein a transmission gear unit is employed to provide said device with the continuous unidirectional rotating torque, said device further comprises a driving wheel and a follower wheel, the mechanical power output of said driving wheel is transmitted to said follower wheel, said driving wheel is composed of a ratchet wheel, several ratchet pawls and an external wheel, said ratchet wheel is engaged to said mandrel with more than one ratchet pawls distributed around its rim, an elastic element is interposed between each said ratchet pawl and said ratchet wheel serving as a cushion, said external wheel is rotatably sleeved on said mandrel and having several detents formed along the inner circumference thereof, and said detents are to be in mesh with said ratchet pawls.

Abstract
In an electricity generating device by applying vehicle weight, a rolling vehicle wheel is weighting down on a pressure receiver to actuate a driving mechanism having a restoring function. It is then able to provide a unidirectional rotating torque to drive a generating device to produce electrical power. The mechanical power transmission is performed by a transmission gear unit composed of a driving wheel and a follower wheel interconnected each other with a transmission means therebetween. When the vehicle weight is applied to the driving mechanism by pressing the vehicle wheel on the pressure receiver, the driving mechanism is forced to downwardly urge a ratchet wheel and a driving wheel to rotate that in turn causes the rotation of the follower wheel through the transmission means thereby driving the generating device to operate to produce electricity. The driving mechanism can recover its initial state with the aid of a balancing weight as soon as it has been liberate from the exerted pressure of the vehicle wheel. The device is to be installed flush with the road surface to work.
