Abstract

A vehicle motion detector and control device arrangement includes a casing, a rotor rotated with the transmission line of the cable of the mileage meter of the motor vehicle in the casing, a rotary driven member revolvably supported on a damping oil in an annular end chamber of the rotary member and maintained in the middle position by magnetic expulsive force, and switch means mounted outside the casing and induced by a magnet at the rotary driven member to turn on a control device of the motor vehicle upon operation of the motor vehicle.

Claims5

Dependent claims

A vehicle motion detector and control device arrangement comprising:

a casing, said casing comprising two symmetrical half shells fastened together and secured to the sleeve of the cable of the mileage meter of a motor vehicle for enabling the transmission line of the cable of the mileage meter to pass axially through said casing, said casing comprising two radial holes disposed at two sides, and two magnets respectively mounted in said radial holes;
a rotor mounted in said casing and rotated with the transmission line of the cable of the mileage meter of the motor vehicle upon starting of the motor vehicle, said rotor comprising an axial through hole, which receives the transmission line of the cable of the mileage meter of the motor vehicle, an annular chamber at a top end thereof around the axial through hole of said rotor, and a damping oil filled in said annular chamber;
a rotary driven member suspending in said casing, said rotary driven member comprising a tubular body disposed around the transmission line of the cable of the mileage cable of the motor vehicle, a lug extended from the periphery of an upper end of said tubular body, a first magnet fixedly mounted in said lug and aimed between the magnets of said casing, said first magnet having the polarity of the two distal ends of said first magnet being reversed to the polarity of the magnets of said casing, a second magnet mounted in the periphery of said tubular body, and a third magnet mounted in the periphery of said tubular body;
a circuit board mounted on said casing at one side, said circuit board comprising switch means;
and
a control device controlled to work by said switch means of said circuit board;
wherein the first magnet of said rotary driven member is forced by the magnets of said casing to keep said rotary driven member in a middle position where the second and third magnets of said rotary driven member are equally spaced from the switch means of said circuit board and the switch means of said circuit board is off when the motor vehicle is turned off;
one of the second and third magnets of said rotary driven member is moved with said rotary driven member to induce the switch means of said circuit board when the motor vehicle is started and moved forwards or backwards, causing said switch means to turn on said control device.
