Description
Technical field
It the utility model is related to magnetoelectricity vibrating sensor technical field.
Background technology
Magnetoelectricity vibrating sensor is to utilize electromagnetic induction principle, the biography that input motion velocity transformation is exported into induced potential
Sensor, it can be converted into the mechanical energy of measurand the electric signal for being easy to measurement.In the prior art, magnetoelectricity vibrating sensor its
Internal structure includes coil block, magnet steel, spring and magnetic conductive shell, and coil block is fixed in magnetic conductive shell, and magnet steel, which is placed in, leads
In magnetic shell, the upper end of magnet steel connects one end of a spring, the other end connection magnetic conductive shell top of the spring, the lower end of magnet steel
One end of another spring is connected, the other end connection magnetic conductive shell bottom of another spring, in the respectively connection one of magnet steel upper and lower ends
Individual spring forms second-order system.
The defects of magnetoelectricity vibrating sensor, is：In actual design, due to that spring rate can not be made to too small, make
Sensor low frequency performance is poor, constrain the low frequency small size design of magnetoelectricity vibrating sensor, and bring can for the presence of spring
By sex chromosome mosaicism.
In view of this, the utility model develops a kind of magnetoelectricity vibrating sensor for overcoming the defect, thus this case is produced
It is raw.
Utility model content
The purpose of this utility model is to provide a kind of magnetoelectricity vibrating sensor, to realize the low frequency of magnetoelectricity vibrating sensor
Change and small size designs, improve the unfailing performance of product.
In order to reach above-mentioned purpose, solution of the present utility model is：
A kind of magnetoelectricity vibrating sensor, including magnetic conductive shell, coil block and magnetic steel component；Coil block is fixed on magnetic conduction
In shell, magnetic steel component is arranged in magnetic conductive shell by upper and lower axle in a manner of mobile, and coil block be located at magnetic conductive shell inner side
Between wall and magnetic steel component.
Further, magnetic conductive shell inner sidewall upper portion and bottom set three bearings, three bearings of upper and lower part respectively
Vertically set, three bearings are equidistantly uniformly distributed and radially, are formed between three bearings and are allowed bit space, magnetic
Allowing in bit space between the three of upper and lower part bearings moves up and down respectively for the top and bottom of steel component, top and under
The excircle of three bearings in portion is born against axially to be moved up and down in the top and bottom of magnetic steel component, bearings magnetic steel component
It is dynamic.
After such scheme, the utility model magnetoelectricity vibrating sensor is fixedly mounted on measured body, with measured body
Vibration, magnetic conductive shell and coil block are and then vibrated together, and magnetic steel component remains stationary as relative to ground, and coil block is cut
Cut magnetic induction line and produce signal, magnetic force between magnetic steel component and magnetic conductive shell be present, produced in magnetic steel component and magnetic conductive shell relative
During reciprocating motion, the size and Orientation of magnetic force is also changing, and is equivalent to a spring.The equivalent spring it is firm
Degree can be designed according to magnetic steel component and magnetic conductive shell, so as to realize that the low frequency of magnetoelectricity vibrating sensor and small size are set
Meter, improve the unfailing performance of product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Label declaration
The coil block 2 of magnetic conductive shell 1
The bearing 4 of magnetic steel component 3.
Embodiment
The utility model is described in detail below in conjunction with drawings and the specific embodiments.
Refer to described in Fig. 1, a kind of magnetoelectricity vibrating sensor that the utility model discloses, including magnetic conductive shell 1, coil group
Part 2 and magnetic steel component 3.
Coil block 2 is fixed in magnetic conductive shell 1, and magnetic steel component 3 is arranged on outside magnetic conduction by upper and lower axle in a manner of mobile
In shell 1, coil block 2 is between the madial wall of magnetic conductive shell 1 and magnetic steel component 3.
The utility model magnetoelectricity vibrating sensor is fixedly mounted on measured body, with the vibration of measured body, magnetic conductive shell 1
And then vibrated together with coil block 2, and magnetic steel component 3 remains stationary as relative to ground, the cutting magnetic induction line of coil block 2 produces
Signal so that magnetic force be present between magnetic steel component 3 and magnetic conductive shell 1, produced in magnetic steel component 3 and magnetic conductive shell 1 relatively reciprocal
During motion, the size and Orientation of magnetic force is also changing, and is equivalent to a spring.The rigidity of the equivalent spring can
To be designed according to magnetic steel component 3 and magnetic conductive shell 1, so as to realize that the low frequency of magnetoelectricity vibrating sensor and small size are set
Meter, improve the unfailing performance of product.
In the present embodiment, the inner sidewall upper portion of magnetic conductive shell 1 and bottom set three bearings 4 respectively, totally six bearings 4, on
Three bearings 4 of portion and bottom are vertically set, and three bearings 4 are equidistantly uniformly distributed and radially, i.e. three axles
It is separated by 120 degree between holding 4, is formed between three bearings 4 and allow bit space, the top and bottom of magnetic steel component 3 are respectively on top
Allowing in bit space between three bearings 4 of bottom moves up and down, and the excircle of three bearings 4 of upper and lower part supports respectively
The top and bottom of magnetic steel component 3 are leaned against, bearing 4 supports magnetic steel component to be moved axially about 3, so as to reduce friction.
Preferred embodiment of the present utility model is the foregoing is only, not to the limitation of this case design, all setting according to this case
The crucial equivalent variations done of meter, each fall within the protection domain of this case.
