Abstract
The utility model relates to a kind of reed switch formula vehicle speed sensor, is made up of magnet, reed switch, wire.Described magnet is arranged on power output shaft or drives on wheel, and described reed switch is installed and driven on wheel, and described reed switch two ends are provided with the wire of connection.Technique effect of the present utility model is: structure is simple and convenient, solves the transmission problem of electric motor car speed information.
Description
Technical field
The utility model relates to vehicle technology field, is specifically related to a kind of reed switch formula vehicle speed sensor.
Background technology
When electric bicycle speed of a motor vehicle when descending exceedes the setting speed of a motor vehicle or car brakeing, charging device works, the kinetic transformation travelled by vehicle is electric energy, limit the further rising of vehicle rotating speed, also play the effect of auxiliary braking during braking, improve the single charge distance travelled of electric bicycle, and electric bicycle is often in charged state, battery can be prevented to be in over-discharge state, to extend the serviceable life of accumulator.Speed information is needed immediately to be transported to controller in this process.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of reed switch formula vehicle speed sensor, solves the transportation problem of speed information in said process.
The technical solution of the utility model is: a kind of reed switch formula vehicle speed sensor, is made up of magnet, reed switch, wire.Described magnet is arranged on power output shaft or drives on wheel, and described reed switch is installed and driven on wheel, and described reed switch two ends are provided with the wire of connection.
Technique effect of the present utility model is: structure is simple and convenient, solves the transmission problem of electric motor car speed information.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 magnet; 2 power output shaft; 3 reed switchs; 4 wires.
Embodiment
A kind of reed switch formula vehicle speed sensor, is made up of magnet 1, reed switch 3, wire 4.Described magnet 1 is arranged on power output shaft 2 or drives on wheel, and described reed switch 3 is installed and driven on wheel, and described reed switch 3 two ends are provided with the wire 4 of connection.
Magnet 1 is arranged on power output shaft 2 or drives on wheel, and when power output shaft 2 or rotation of wheel, the polarity of the magnet 1 of rotation just changes relative to reed switch 3, thus one one, the contact of reed switch 3 is closed; Magnet 1 often turns 1 circle, the reversal of magnet 14 times, the closing of contact of reed switch 3 or disconnect 4 times.When power switch close and power output shaft 2 or rotation of wheel, reed switch 3 just produces pulse signal, its signal pulse frequency is directly proportional to power output shaft 2 or vehicle wheel rotational speed, thus realization outputs power, the tach signal of axle 2 or wheel and the vehicle speed signal of electric bicycle become electric signal and flow to controller.Technique effect of the present utility model is: structure is simple and convenient, solves the transmission problem of electric motor car speed information.
Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
