Description
Technical field
The utility model relates to the automobile component field, is specifically related to a kind of electronic accelerator pedal assembly.
Background technology
Be the oil inlet quantity of controlling machine motor-car cylinder, and then the rotating speed and the power of control driving engine, the final control that realizes motor vehicle speed all is provided with the Das Gaspedal assembly in the operator's compartment of self-propelled vehicle.Traditional Das Gaspedal assembly is mostly realized accelerator open degree control through connecting rod or drag-line, and its a series of actions is mechanical movement.But because a series of actions of this Das Gaspedal assembly all is mechanical movement, make its transmission accuracy and sensitivity not high, electronic accelerator pedal assembly just occurred in order to address the above problem.Electronic accelerator pedal assembly is divided into contact-type electronic Das Gaspedal assembly and non-contact electronic acceleration pedal assembly at present; But shortcomings such as production technology bothers because contact-type electronic Das Gaspedal assembly exists, service life is short; Therefore, the non-contact electronic acceleration pedal assembly is more favored by people.
The patent No. is that the Chinese utility model patent of ZL201020146281.9 discloses a kind of non-contact electronic acceleration pedal assembly; It comprises pedal, contactless sensing device, pedestal; Sensing device comprises magnetic guiding loop, wiring board, sensor and two square magnets that are oppositely arranged; The magnetic guiding loop of sensing device is connected with pedal through pedal shaft, and two square magnets that are oppositely arranged are fixed in the magnetic guiding loop, and sensor is installed between two magnet in the magnetic guiding loop.During use, sensing device is connected with automobile computer, when foot pedal; Pedal shaft and connected magnetic guiding loop rotate; Magnetic guiding loop rotates, and the relative angle of uniform magnetic field and sensor changes between two square magnets, and sensor receives this variable signal; The voltage of sensing device output is changed, and automobile computer carries out control corresponding to automotive system again according to the voltage signal that receives.But there is following defective in this non-contact electronic acceleration pedal assembly: because inductor is to carry out signal conditioning through the variation of responding to magnetic field between two magnet that are oppositely arranged; And two magnet that are oppositely arranged are because its magnetic field exists only in two inner spaces that magnet is relative; The angle that inductor can be responded to changes relatively limited; The amplitude that steps up and down that this has limited pedal has also limited the control dynamics and the precision of electronic accelerator pedal assembly.
The utility model content
The utility model technical matters to be solved is the deficiency to above prior art, and it is big to provide a kind of pedal to step amplitude, control great efforts, the electronic accelerator pedal assembly that control accuracy is high.
For addressing the above problem, the utility model provides a kind of electronic accelerator pedal assembly, comprises pedal, base, contactless sensing device.Said pedal comprises treadle, first rotating shaft of captive joint; Said contactless sensing device comprises shell, sensor, magnet, magnetic guiding loop, wiring board and second rotating shaft; Second rotating shaft is captiveed joint with first rotating shaft; Magnet is connected in second rotating shaft, and wiring board is fixing in the enclosure, and sensor is fixing in the circuit board.Said magnet is two blocks of circular arc magnet that are oppositely arranged, and said sensor is between two blocks of circular arc magnet that is oppositely arranged.
After adopting above structure; The utility model compared with prior art has the following advantages: used magnet is two blocks of circular arc magnet that are oppositely arranged in the contactless sensing device of the utility model, and circular arc magnet is for square magnet of the prior art; Its magnetic field range is bigger; Magnetic field is stronger, allow the angle of inductor induction change also than in the prior art greatly, this makes that the amplitude that steps up and down of pedal is bigger; Thereby increased the control dynamics of electronic accelerator pedal assembly, improved the control accuracy of electronic accelerator pedal assembly.
