Abstract
The utility model discloses a velocity and mileage sensor, essentially consisting of a rotation shaft 1 and a housing 2, wherein the rotation shaft 1 is arranged on one end of the housing 2, the rotation shaft 1 is connected with the housing 2 through a double shaft sleeve 3 which is a plastic shaft sleeve with self-lubricating function, a magnet ring is arranged on one end of the rotation shaft 1, a plug seat 6 which is provided with a wiring board 7 is arranged on the other end of the housing 2, a Hall component 5 is connected with the wiring board 7. The utility model achieves simple structure and high accuracy through the above arrangement, thereby can be widely applied in the field of automotive fitting parts.
Description
Technical field
The utility model relates to a kind of sensor, particularly relates to a kind of vehicle speed sensor of using hall device.
Background technology
Adopting the vehicle speed sensor of hall device is a kind of new car speed sensors that occurs along with the development of microelectric technique and high performance permanent magnetic materials.Hall device is a class that belongs to Magnetic Sensor, and it is a kind of to the magnetic induction density sensitivity, and can be the sensor of electrical information with the information translation of magnetics amount.Compare with traditional vehicle speed sensor, maximum characteristics are the axle center rotating parts that do not have machinery, and the plurality of advantages of bringing therefrom, as acquired signal accurately and reliably and versatility good, obtained increasing application in the last few years.But, drawback such as there is complex structure in existing vehicle speed mileage sensor, and degree of accuracy is low.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the accurate vehicle speed mileage sensor of signals collecting.
For reaching above purpose, vehicle speed mileage sensor, mainly form by rotating shaft 1, housing 2, end at housing 2 is provided with rotating shaft 1, and rotating shaft 1 is connected by two axle sleeves 3 with housing 2, and two axle sleeves 3 are the plastic sleeve of self-lubricating function, end in rotating shaft 1 is provided with magnet ring 4, the other end at housing 2 is provided with socket 6, is provided with wiring board 7 on socket 6, and Hall element 5 is connected with wiring board 7.
By above setting, rotating shaft 1 cooperates with multi-pole magnet-ring 4 by square hole or semicircle orifice, the rotating shaft axle sleeve adopts the plastic sleeve 3 with self-lubricating function, effectively avoided the mechanical friction problem, multi-pole magnet-ring 4 produces relative motion with peripheral locking-typed Hall element 5, thereby produce a series of square-wave signals and pass to instrument, simple in structure, the degree of accuracy height.
