Abstract
The utility model discloses an automobile electric inducing switch, which comprises a casing, a magnetic inducing element for detecting the change of the magnetic field strength and a control circuit. The magnetic inducing element is connected with the control circuit, the magnetic inducing element is provided at the front end of the casing, a magnet is arranged near the magnetic inducing element, and the front wall of the casing adopts non-magnetic material. The utility model utilizes hall element to induce the change of the magnetic field to control the switching of the witch, having better sensibility and reliability. The structure is simple and the operation is convenient.
Description
1, technical field:
The utility model relates to a kind of automotive electronics inductive switch.
2, background technology:
Tradition is applied to the switch that automobile uses, it mostly is mechanical contact switch, as: brake lamp switch, Reverse lamp switch and driving switch etc., this mechanical contact switch is to promote this switch contact closure by stroke lever, realize relevant work, because this mechanical contact switch is to realize its corresponding function by the effect that each relevant portion directly contacts by power, reliability is relatively poor, and is sensitive inadequately, and switch contact can wear and tear after long-time the use, make its action actual effect easily, this is unfavorable for the safety traffic of automobile, and in addition, some switch contacts are operated in the oil pressure unit, long-term extruding is made the leakage of oil situation easily and is occurred, and has influenced the operate as normal of vehicle switch.
3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of automotive electronics inductive switch.
The utility model is achieved by the following technical solution:
A kind of automotive electronics inductive switch, comprise housing, be used to detect the magnetosensitive sensing element and the control circuit of change of magnetic field strength, the magnetosensitive sensing element is connected with control circuit, the magnetosensitive sensing element is being arranged on the front end of housing, the place is provided with magnet at contiguous magnetosensitive sensing element, and the antetheca of described housing is non-magnetic conductive material.It is to utilize the magnetosensitive sensing element to the changes of magnetic field of its residing position and produce switching signal, be used as when magnetic conductor is toward or away from the housing antetheca on the mechanical device that relatively moves, to cause the formed changes of magnetic field of the magnet in the housing, and trigger corresponding switching signal.
Such scheme can be further improved by following measure:
Above-mentioned described magnet is bar magnet, and a magnetic pole of this bar magnet is towards the antetheca of housing.
Above-mentioned described magnetosensitive sensing element can be Hall element or tongue tube or winding coil.
Above-mentioned described control circuit output is provided with power tube T.
The utility model compared with prior art has following advantage: the break-make of 1) utilizing magnetosensitive sense element senses changes of magnetic field to come control switch, because magnetosensitive sense element senses sensitivity makes the action of switch sensitive more, avoids making switch failure because of contact wear, the reliability height, fail safe is good; 2) control circuit uses power tube output, exportable bigger electric current, and the automobile component switch that is fit to the big current start of more needs uses; 3) utilize short-circuit protection circuit, prevent that circuit from making switch failure because of short circuit, switch is more reliable and more stable; 4) simple in structure, easy to operate.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is control circuit figure of the present utility model.
5, embodiment:
As shown in Figure 1 and Figure 2, the utility model comprises housing 1, is used to detect the magnetosensitive sensing element 2 and the control circuit 3 of change of magnetic field strength, magnetosensitive sensing element 2 is connected with control circuit 3, magnetosensitive sensing element 2 is at the front end that is arranged on housing 1,2 places are provided with magnet 4 at contiguous magnetosensitive sensing element, and the antetheca of described housing 1 is non-magnetic conductive material.Magnet 4 is bar magnet, and a magnetic pole of this bar magnet is towards the antetheca of housing 1, and control circuit 3 outputs are provided with power tube T, and the magnetosensitive sensing element 2 in the present embodiment is Hall elements, and available in actual use tongue tube or winding coil replace Hall element.
Operation principle of the present utility model: as shown in Figure 1 and Figure 2, be used as when magnetic conductor 5 is near housing 1 antetheca on the mechanical device that relatively moves, to cause the formed changes of magnetic field of the magnet 4 in the housing 1, magnetic conductor 5, magnet 4 and Hall element form toroidal magnetic circuit 6, Hall element is connected, make the power connection of control circuit 3, make switch be in conducting state; And when magnetic conductor 5 leaves, formed toroidal magnetic circuit 6 originally to disconnect, near the field weakening the Hall element, Hall element disconnect, and control circuit also disconnects thereupon, makes switch be in off-state.
The operation principle of the utility model control circuit: as shown in Figure 2, behind the power connection of control circuit 3, G signal end ground connection, power tube T conducting, the output of power tube T is connected load 7, i.e. switch conduction; And after power supply disconnected, the G signal end was a high level, and power tube T closes, and switch is in off-state.If during the output head grounding of power tube T, can make capacitor C 1 charging, capacitor C 1 instantaneous short circuit; make T1 connect, thereby power tube T place is had oppositely by voltage, T closes; among the figure, R3 and T2 are that protective circuit is kept in short circuit, thereby avoid the infringement of short circuit to control circuit 3.
