Abstract

The utility model relates to an electronic sensor footplate comprising a base, a rotation axis in the base, a lever arm connected with the rotation axis, a footplate connected with the side of the lever arm, a torsional spring on the rotation axis, characterized in that the sense base is arranged on the rotation axis and the sensor is arranged on the base. A sensor element base equipped with the sensor element corresponding to the sensor on the sensor base is disposed on the rotation axis and the sensor is connected with the controller by the lead. The utility model has the advantages of accurate and reliable signal gathered, the footplate lever arm rotation angle signal transmitted to the controller ahead of time and the signal processed by the controller in time to send out the instruction to decelerate, not only saving the fuel oil, but also enhancing the reliability of the quality. The utility model is suitable for the brake pedal and the accelerator pedal.

Description

The electronic sensor pedal

Technical field

The utility model relates to the automobile-use pedal, is specifically related to be used for the electronic sensor pedal of motor vehicle gasoline throttle or braking.

Background technology

Pedal is the steering unit of self-propelled vehicle control throttle or drg, has directly reflected the will of chaufeur and the motoring condition of vehicle.Along with the application of electron controls technology on self-propelled vehicle, the signal of gathering pedal is sent to controller and carries out comprehensive treatment, is the requisite measure that improves controlling level.At present, the technology of Yi You aspect.But the sensor cost height that has, the vibration environment in the incompatibility vehicle ' process; The signal of the collection that has and the non-linear relation of pedal corner, the precision of influence control; The processing technology complexity that has, the cost height.Therefore, existing electronic sensor pedal exists improved demand.

Summary of the invention

The purpose of this utility model provides a kind of electronic sensor pedal that is used for motor vehicle gasoline throttle or braking, and it can pass to controller to the angle signal that the foot pedal lever arm rotates in advance, improves reliability qualitatively, saves fuel oil, and simple in structure, and cost is low.

Electronic sensor pedal described in the utility model, comprise pedal base, be located at rotating shaft, fulcrum on the pedal base be fixedly connected on throw of lever in the rotating shaft, be fixedly connected on throw of lever one end pedal, be located at the torsion spring in the rotating shaft, one end of torsion spring leans against on the pedal base, the other end is hooked on the throw of lever, it is characterized in that: be provided with sensor holder in rotating shaft, sensor is located on the sensor holder; Also be provided with the sensitive member seat in rotating shaft, sensitive member is fixed on the sensitive member seat, and corresponding with sensor on the sensor holder, and sensor is connected with controller by lead.

Described electronic sensor pedal, the sensor that is located on the sensor holder is a linear hall sensor, is located at that sensitive member is the arc magnet steel on the sensitive member seat.Because the sensitive member seat is fixed in the rotating shaft, when stepping on or unclamp pedal, the sensitive member seat all rotates thereupon, the sensitive member that is fixed on the sensitive member seat also rotates thereupon, sensor will collect the variable signal of arc magnet steel magnetic-field intensity, and promptly the signal of angular transposition passes to the controller processing by lead.

Described electronic sensor pedal, the screw that passes through of its sensor holder is connected on the pedal base, and the sensing unit seat is fixed in the rotating shaft by straight pin.

The utility model is compared with prior art and had the following advantages: the signal of collection accurately and reliably, the rotational angle signal of foot pedal lever arm can pass to controller in advance, controller is received the laggard timely row processing of signal, sending instruction slows down, not only fuel oil can be saved, reliability qualitatively can also be improved.Both be applicable to brake pedal, be applicable to Das Gaspedal again.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Referring to Fig. 1, Fig. 2 and Fig. 3, pedal 4 is welded on an end of throw of lever 3, the fulcrum at throw of lever 3 middle parts is welded on the end of rotating shaft 2, one end of rotating shaft 2 passes the mounting hole on the pedal base 1, torsion spring 5 is enclosed within the rotating shaft, one end of torsion spring is leaned against on the pedal base, and the other end is hooked on the throw of lever;

To be fixed on for the sensitive member 9 of arc magnet steel on the sensitive member seat 8, sensitive member seat 8 is fixed in the rotating shaft 2 by straight pin 11; For the sensor 7 of linear hall sensor is installed on the sensor holder 6, sensor holder 6 is enclosed within the rotating shaft 2, and sensor holder 6 is connected on the pedal base 1 by screw 10, and sensor 7 is corresponding with sensitive member 9.

During use, pedal base is installed and fixed onboard, throw of lever and control of braking wire joint, sensor are connected with controller by lead and get final product.
