Abstract
The invention discloses a vehicle speed sensor comprising a parking locking gear and a voice broadcaster. The voice broadcaster is provided with holes in the surface. The parking locking gear is internally equipped with a magnetic flux sensor which is electrically connected with an electronic control component. The surface of the electronic control component is connected with the two ends of an induction tube through wires. The surface of the induction tube is wound with an induction coil of which one end is connected with a permanent magnet. One side of the electronic control component is connected with the voice broadcaster through a wire. According to the vehicle speed sensor, the parking locking gear is arranged, and when the convex teeth of the parking locking gear gradually move close to or away from the induction coil, the magnetic flux inside the coil can change, and thus alternating current is produced; as the electronic control component is arranged, the running speed of a vehicle can be calculated according to the frequency of induced voltage pulse provided by the induction coil; and by setting the voice broadcaster, the speed of a vehicle can be known more conveniently.
Description
Technical field
The present invention relates to automotive sensor technology field, specially a kind of vehicle speed sensor.
Background technology
Vehicle speed sensor is a kind of speed measuring device, is that motorcycle and automobile are indicated in being widely used in motorcycle and automobile
Instrument provides rate signal, and currently on the market conventional velocity sensor has shaft type and induction two big class, rotary shaft,
Speed is passed out by rotating shaft, to a little electromotor, according to the voltage that electromotor is set up, extrapolates rotating speed, it will
Seek the quality of axle, on one wire, otherwise axle is easily broken off either with or without really with the axle that rotates when also installation, electromagnetism sense
Formula is answered, gear is installed on the axle for rotating, outside is solenoid, and rotation is, because clearance between gear teeth passes through, to obtain square-wave variations
Voltage, then extrapolate rotating speed, fairly simple convenience, and current speed is by pointer representation, it appears that cumbersome.
The content of the invention
It is an object of the invention to provide a kind of vehicle speed sensor, to solve the problems, such as above-mentioned background technology in propose.
For achieving the above object, the present invention provides following technical scheme：A kind of vehicle speed sensor, including park lock gear
And voice announcer, the surface of the voice announcer offers hole, and the inside of the park lock gear is provided with magnetic flux biography
Sensor, and the magnetic flux transducer electrically connects with electrically-controlled component, the surface of the electrically-controlled component is by wire and induction tube
Two ends connect, and the surface wrap of the induction tube is provided with induction coil, and one end of the induction tube is connected with permanent magnet, institute
The side for stating electrically-controlled component is connected by wire with voice announcer.
Preferably, the inside in the hole is provided with Air Filter.
Preferably, the side of the voice announcer is provided with circumscripted power line.
Compared with prior art, the invention has the beneficial effects as follows：The vehicle speed sensor, by arranging park lock gear,
When the double wedge of park lock gear is constantly close or leaves induction coil, the magnetic flux in coil can be made to change,
So as to produce alternating current, by arranging electrically-controlled component, the frequency of the induced voltage pulse that can be provided by induction coil is calculated
Automobile driving speed, by arranging voice announcer, understanding speed that can be convenient, by arranging Air Filter, Neng Goufang
Only the hole of voice announcer blocks.
