Description
Technical field
The utility model relates to a kind of automotive controls, is specifically related to a kind of horn switch of vehicle safety.
Background technology
At present, the horn switch that Domestic Forklift is generally applied comprises horn button, loudspeaker and conduction mechanism thereof, and wherein horn button is integrated in steering wheel, and the wire of horn switch is connected with the conducting ring in steering spindle and is drawn by steering spindle.The negative power supply normal open of loudspeaker, cathode power supply are connected on horn switch, when triggering horn button, conductive pole moves down together with horn button, when touching the conducting ring in steering spindle when conductive pole, horn switch closes, make the positive source conducting of loudspeaker, and the loudspeaker be serially connected with in this loop just start to report to the police.When the hand of operator leaves horn button, under the effect of back-moving spring, horn button together with conductive pole on move, switch no longer conducting after the conducting ring in conductive pole and steering spindle departs from, the loudspeaker power-off be at this moment serially connected with in loop is no longer reported to the police.The loudspeaker conduction mechanism of this structure has higher failure rate.Due to when fork-truck steering, the wire of horn switch, with steering axes, easily causes the disengaging of wire and conducting ring to be lost efficacy; Secondly, because conductive pole and conducting ring contact area are less, after repeatedly triggering horn button, the contact-making surface of conductive pole easily produces arcing and to burn the phenomenon of losing.
Utility model content
The utility model, in order to solve the problems of the technologies described above, provides a kind of horn switch of vehicle safety, avoids horn switch lead-in wire and departs to lose efficacy and burn lose the generation of phenomenon with contact arc discharge.
The technical solution of the utility model is: a kind of horn switch of vehicle safety, comprise loudspeaker and be integrated in the horn button in steering wheel, the below of described horn button is provided with conduction mechanism, described conduction mechanism comprises the first conductive pole and the second conductive pole, the top of described first conductive pole and the second conductive pole is positioned at immediately below described horn button, the bottom of the first conductive pole and the second conductive pole is equipped with spring, a wire is respectively welded in the bottom of the first conductive pole and the second conductive pole, and the other end of described wire respectively connects a conductive copper sheet; The cathode power supply of described loudspeaker is serially connected between two conductive copper sheets.
Further, described horn button comprises the column be installed in below upper cover plate, and the bottom of described column is provided with conductive reed, and one end and the outer conducting ring of described conductive reed are affixed, the other end is positioned at directly over conducting ring; The top of described first conductive pole is positioned at immediately below described conducting ring, and the top of the second conductive pole is positioned at immediately below outer conducting ring.
Further, described conduction mechanism is located at the inside of the switch module be positioned at below steering wheel, the centre of described switch module offers the installing hole matched with steering column assembly, and switch module is set on steering column assembly by described installing hole, and the bottom of switch module is connected with mounting bracket.
Further, the bottom of described spring is fixedly arranged on spring seat.
Further, described column has three, and its spacing is each other equal.
Steering column for vehicle assembly comprises mounting bracket and is located at the steering spindle in steering column, and steering wheel is located at steering spindle top, drives steering spindle to rotate together when it rotates.
When needs trigger horn button, pressing is positioned at the upper cover plate in the middle of steering wheel, the band column be automatically connected in below upper cover plate moves down, and the conductive reed be positioned at immediately below its bottom is contacted with conducting ring, and interior conducting ring is connected by conductive reed and outer conducting ring; And first conductive pole of the inside and outside conducting ring of conducting respectively through contacting with it and the second conductive pole and two conductive copper sheets are connected, make the positive source conducting of loudspeaker, so make the loudspeaker be serially connected with in this loop connect circuit and start to report to the police.When the hand of operator leaves horn button, in horn button, conductive reed is along with column up shift-in horizontal reset, thus disconnects the connection between inside and outside conducting ring, makes horn circuit disconnect and quit work.When steering wheel rotation, the horn button be integrated in steering wheel rotates with steering wheel; And the conduction mechanism being located at switch module inside is owing to being set on steering column assembly; when steering axes; switch module can't rotate along with steering axes, thus protects the use safety of the wire of horn switch, the circuit malfunction faults such as wire fracture can not occur.
In addition, under the pressure effect of spring, the top of the first conductive pole and the second conductive pole is in contact condition respectively and between the bottom face of inside and outside conducting ring always, so at steering wheel rotation and when triggering horn button, the top end face of the first conductive pole and the second conductive pole can not produce galvano-cautery.
So the utility model has following remarkable result:
1, because the wire of horn switch of the present utility model is integrated in switch module, therefore when rotating of steering wheel, its wire can not rotate with rotation axis, eliminates wire and inside and outside conducting ring in traditional structure and departs from the phenomenon of the failure lost efficacy.
2, the connecting and disconnecting of the circuit of horn switch is realized being switched on or switched off between interior conducting ring and outer conducting ring by conductive reed, and its contact area is comparatively large, and the galvano-cautery phenomenons such as arcing are less likely to occur.And the top of the first conductive pole, the second conductive pole is in contact condition respectively and between the bottom face of inside and outside conducting ring always, so at steering wheel rotation and when triggering horn button, the top end face of the first conductive pole and the second conductive pole can not produce galvano-cautery.
3, due under upper cover plate equalization three columns are set, thus pressing dynamics is acted on three conductive reeds equably, makes three conductive reeds contact with interior conducting ring and contact with outer conducting ring simultaneously.
