Description
Technical field:
The utility model relates to sensor technical field, relates in particular to a kind of induction contactless inclination sensor.
Background technology:
In the vehicles such as a lot of automobiles, aircraft, elevator and the plant equipment, the inclination sensor that is used for the inspected object angle of inclination all is installed, these vehicles and plant equipment can be adjusted devices such as control generator according to the detected angle of inclination of inclination sensor, think to keep its correct set, steadily of centre of gravity.As the Chinese patent notification number is the disclosed a kind of inclination sensor of CN2929651, it is by Hall element, can swing magnet steel and housing constitutes, dispose weight in the housing, magnet steel is installed on this weight, weight can freely swing in the certain limit in housing, linear hall element is installed in the housing, owing to be subjected to gravitational effect weight all the time perpendicular to surface level, therefore when the installed surface of sensor during horizontal by certain angle Hall element produce between with respect to magnet steel and be offset, voltage or output resistance by Hall element output change, thus the heeling condition of detecting.The weight of this kind inclination sensor is to be suspended in the housing, i.e. mechanical connection is when weight is swung, can there be certain mechanical friction power in the end that weight hangs, make the detection signal of inclination sensor have certain error, therefore, the induction sensitivity of this inclination sensor is not high.
The utility model content:
The purpose of this utility model is exactly to provide a kind of highly sensitive induction contactless inclination sensor at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is:
It comprises loam cake, lower cover, loam cake and lower cover fasten mutually and sealing, it is cursory to be provided with between described loam cake and the lower cover, be injected with between the cursory and lower cover and can supply the cursory buoyancy liquid that freely swings, describedly be mounted with magnet on cursory, the top of described loam cake is fixed with and is used to respond to the magnetic induction chip that changes with the magnet relative angle.
Wherein, described magnetic induction chip is magnetic resistance (MR, a Magneto Resistive) sensor chip.
Wherein, cover under described and offer groove, form pillar on the cursory both sides with the groove coupling.
Wherein, described cursory base, the last fixed block of comprising, last fixed block is fixed in the base, and described magnet is fixed on the fixed block, and described base swims on the buoyancy liquid.
Wherein, the bottom of described lower cover is fixedly connected with shell.
Wherein, the open top of described shell, opening part is equipped with pcb board (printed circuit board (PCB)), and described magnetic induction chip is electrically connected with pcb board.
The utility model beneficial effect is:
The induction contactless inclination sensor that the utility model provides comprises loam cake, lower cover, loam cake and lower cover fasten mutually and sealing, it is cursory to be provided with between described loam cake and the lower cover, be injected with between the cursory and lower cover and can supply the cursory buoyancy liquid that freely swings, describedly be mounted with magnet on cursory, the top of described loam cake is fixed with and is used to respond to the magnetic induction chip that changes with the magnet relative angle, because it is cursory for swimming on the buoyancy liquid, therefore cursoryly can be in surface level all the time, when the installed surface of sensor during horizontal by certain angle, the magnetic induction chip that is fixed on the loam cake top is with respect to producing skew between the magnet, induce the angle of skew by the magnetic induction chip, and export corresponding electric signal, thereby the heeling condition of detecting.Compare with existing inclination sensor, magnet of the present utility model be fixed on cursory on, and cursory be to swim on the buoyancy liquid, realized contactless inclination sensor, make sensor no longer be subjected to the influence of mechanical friction power, thereby improved the induction sensitivity of inclination sensor.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposing schematic representation of the present utility model;
Fig. 3 is the structural representation of the utility model when being in obliquity.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1,2,3, the utility model comprises loam cake 1, lower cover 2, loam cake 1 fastens mutually and sealing with lower cover 2, be provided with cursory 3 between described loam cake 1 and the lower cover 2, cursory 3 and lower cover 2 between be injected with and can supply the cursory 3 buoyancy liquid 4 that freely swing, be mounted with magnet 5 on described cursory 3, the top of described loam cake 1 is fixed with and is used to respond to the magnetic induction chip 6 that changes with magnet 5 relative angles.Compare with existing inclination sensor, magnet 5 of the present utility model is fixed on cursory 3, and cursory 3 be to swim on the buoyancy liquid 4, has realized contactless inclination sensor, make sensor no longer be subjected to the influence of mechanical friction power, thereby improved the induction sensitivity of inclination sensor.Further, because magnetic induction chip 6 of the present utility model has adopted the magnetoresistive transducer chip, therefore, the utlity model has characteristics such as volume is little, highly sensitive, the linearity is good.
The bottom of present embodiment lower cover 2 is fixedly connected with shell 7, is installed in the vehicles such as automobile, aircraft, elevator and the plant equipment to make things convenient for sensor; The open top of described shell 7, opening part are equipped with pcb board 8, and described magnetic induction chip 6 is electrically connected with pcb board 8, and pcb board 8 is a control signal with the electrical signal conversion of magnetic induction chip 6 outputs, to adjust devices such as controlling generator.
Assembling process of the present utility model is, at first in lower cover 2, inject buoyancy liquid 4, to install and fix cursory 3 of magnet 5 then is placed in the lower cover 2, then, loam cake 1 and lower cover 2 adhesive seal, again magnetic induction chip 6 is fixed on the top of loam cake 1, and magnetic induction chip 6 is electrically connected with pcb board 8, at last, put into and be fixed on shell 7.The utility model in use, because cursory 3 for swimming on the buoyancy liquid 4, therefore cursory 3 can be in surface level all the time, when the installed surface (being the bottom surface of shell 7) of sensor during horizontal by certain angle, the magnetic induction chip 6 that is fixed on loam cake 1 top is with respect to producing skew between the magnet 5, induce the angle of skew by magnetic induction chip 6, and export corresponding electric signal, pcb board 8 is a control signal with the electrical signal conversion of magnetic induction chip 6 outputs, thereby to adjust devices such as controlling generator.
