Abstract
A gear-down switch is disclosed, which comprises a mechanical part and a circuit switch part, wherein the gear-down switch enters in a closed state while achieving a certain power with the driving of an outside man-made power, and the closing of the switch is directly controlled by an outside pressure. The gear-down switch disclosed by the invention can control the opening and closing of another vehicle-mounted device in double conditions that an electronic accelerator pedal is in a full-scale accelerating state and the outside man-made power achieves a threshold.
Description
Technical field
The present invention relates to a kind of artificial external force size and define and the change in displacement system, relating in particular to is a kind of efp control system of commerial vehicle, particularly relates to a kind of kickdown switch.
Background technology
Electronic technology develop rapidly in recent years, electronic accelerator pedal of automobile also along with develop rapidly, early stage the sort of stay-supported gas pedal is eliminated gradually, the substitute is with better function, use novel electron gas pedal more easily.The novel electron gas pedal adopts contactless angular displacement sensor.The efp angular displacement sensor is installed in gas pedal inside, monitors the position of gas pedal at any time.When monitoring the gas pedal height and position when changing; Understand moment with this direct information ECU; ECU carries out computing to the data message of this information and other system; Calculate a control signal, deliver to servo E-Gas motor relay through circuit, servomotor drives air throttle and carries out relevant action.This noncontacting proximity sensor life-span, long reliability was high, and some vehicles can add big foot to step on dynamics in the upward slope open out, and the efp life-span can reduce since then; And just become a key link useful life of therefore how to improve gas pedal drive mechanism part.
Summary of the invention
To above-mentioned situation, the present invention provides a kind of kickdown switch, makes its mode that can control onboard system through stressed variation, to solve the deficiency of prior art.
A kind of kickdown switch comprises mechanical part and circuit and switch sections; It is characterized in that:
Said mechanical part comprises, the sheet metal component shell, and the top of said sheet metal component shell is provided with a force rod, and a fixedly pure iron is arranged at the force rod bottom, and the pure iron bottom is provided with a magnet that attracts pure iron, and the magnet bottom is provided with a stage clip;
Said circuit and switch sections comprise a normal open switch that is arranged at the stage clip right side, and a circuit board is arranged at the normal open switch bottom.
Further, respectively there are 2 circular ports that are used to assemble on sheet metal component shell both sides.
Further, the diameter of said circular port is 6 mm ~ 10 mm, and accepted value is 8 mm.
Beneficial effect of the present invention is that when the stressed toggle area that reaches of force rod, force rod moves down and makes normal open switch closed, reaches switching purposes; And resistance to wear is high, long service life.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a kind of kickdown switch of the present invention schematic internal view.
Fig. 2 is change curve such as the figure below between the stressed and stroke of a kind of kickdown switch of the present invention.
100-force rod among the figure, 200-pure iron, 300-magnet, 400-stage clip, 500-normal open switch, 600-circuit board, 700-fixing hole, 800-sheet metal component shell.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Participate in Fig. 1 Fig. 2, a kind of kickdown switch comprises: mechanical part and contactor part.It is characterized in that a sheet metal component shell 800 is arranged, the top of said sheet metal component shell 800 is provided with a force rod 100, and when outer force urges force rod 100 reached the position of contact D, force rod 100 can move down, and the force rod bottom links to each other partly has a pure iron 200.In the middle of pure iron 200 was positioned at, fixed, external force was passed pure iron 200, promote to be positioned at pure iron 200 bottoms magnet 300 away from pure iron 200, produce strong magnetic attraction, when reaching 100N with the stage clip 400 elastic force summations of magnet below.Magnet 300 can move down 2～3 mm, and promptly the stage clip right side has a normal open switch 500 to connect circuit by bottom one circuit board 600.Make normal open switch 500 closures.In the time of the external force cancellation, switch 500 can return to the initial position when breaking off again.Realize the open and close of onboard system.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
