Abstract
The utility model relates to an electronic accelerator pedal. A roller is fixed on a support through a support shaft and is fastened through a clamp siring. A sensor is fixed on a pedal panel through first screws. One end of a wire harness is fixed to the pedal panel and a bottom board through second screws and a wire clamp; the other end of the wire harness is connected to the sensor. The electronic accelerator pedal has the advantages that delayed response caused by a connection gap between a mechanical portion of the electronic accelerator pedal and the sensor is eliminated thoroughly, real-time response of signals emitted by the sensor to action of a driver pushing an accelerator is achieved, error signals occurring at the reset starting moment of the accelerator pedal are eliminated, and correlated errors between the electrical signals emitted by the sensor and standard signals are decreased.
Description
Technical field
The utility model relates to a kind of angular displacement sensing device, particularly a kind of electronic throttle accelerator pedal of the input media as electronic fuel injection engine controller ECU.
Background technology
What electronic accelerator pedal used at present is the structure that sensor axis separates with magnet steel, magnet steel is placed in sensor internal, when acceleration pedal moves, drives sensor axis to move together, thereby drive the magnet steel motion of sensor internal, Hall chip magnetic field is around changed, but due to gapped between sensor axis and the structure of sensor, when axle has fine rotation, due to the existence in gap, the magnet steel of sensor internal can not rotate, and causes control inaccuracy, occurs very large error.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of accelerating throttle pedal, and this pedal combines sensor axis and magnet steel, controls thereby realize accurately.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of electronic throttle accelerator pedal, comprises base plate, pedal panel, wire harness, sensor, described the first screw, support, roller, support shaft, jump ring, sensor axis, volute spiral spring, lining, described the second screw, line card, base plate axle, torsion spring, Hall chip, circuit card, magnet steel, magnetism-isolating loop, lid, elastic cylindrical pin and sensor body; Described roller is fixed on described support by described support shaft, and with described jump ring clamping; Described sensor is fixed on described pedal panel by described the first screw, and one end of described wire harness is separately fixed on described pedal panel and described base plate by described the second screw and described line card, and the other end is connected on described sensor.
Good effect of the present utility model: eliminate the response delay bringing because of efp mechanics and sensor joint gap completely, realize the real-time response of sensor output signal and the action of driver's step on the accelerator; Eliminate Das Gaspedal start the to reset error signal of moment and produce, reduce the correlated error of sensor output electrical signals and standard signal.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of electronic throttle accelerator pedal described in the utility model, comprises base plate 1, pedal panel 2, wire harness 3, sensor 4, the first screw 5, support 6, roller 7, support shaft 8, jump ring 9, sensor axis 10, volute spiral spring 11, lining 12, the second screw 13, line card 14, base plate axle 15, torsion spring 16, lining 17, lining 18, jump ring 19, Hall chip 20, circuit card 21, magnet steel 22, magnetism-isolating loop 23, lid 24, elastic cylindrical pin 25 and sensor body 26.
As shown in Figure 1, roller 7 is fixed on support 6 by support shaft 8, and clamps with jump ring 9.Sensor 4 is fixed on pedal panel 2 by the first screw 5, and one end of wire harness 3 is separately fixed on pedal panel 2 and base plate 1 by the second screw 13 and line card 14, and the other end is connected on sensor 4.
As shown in Figure 2, base plate 1 is fixed on pedal panel 2 by base plate axle 15, and is provided with torsion spring 16 between base plate 1 and pedal panel 2.
As shown in Figure 3, magnet steel 22 and magnetism-isolating loop 23 are arranged in sensor axis 10 Plastic Parts.Two volute spiral springs 11 are separately positioned on support 6 both sides, and sensor axis 10 is fixed on volute spiral spring 11 and support 6 on pedal panel 2 through support 6, support 6 and sensor axis 10 are fixed together with elastic cylindrical pin.Hall chip 20 is welded on circuit card 21, and circuit card 21 is welded in sensor 4 bodies, in sensor 4 bodies, injects AB glue, seals with lid.
As shown in Figure 4, sensor axis is a bridge, is responsible for mechanical movement to be converted to the variation in magnetic field.Formed by a stainless steel shaft (A) and a Plastic Parts (B), Plastic Parts is injection-moulded in one end of stainless steel shaft, and for loading magnet steel and magnetism-isolating loop, changes of magnetic field changes synchronous with regard to energy and angle like this, even if it is very small that sensor axis angle changes, magnetic field also can change.Thereby improve sensitivity.
The working process of electronic throttle accelerator pedal is as follows: in the time of pushes pedals panel, roller on support can roll on base plate, thereby support is rotated, support can drive again sensor axis to rotate together, thereby Hall chip magnetic field is around changed, and needed output electrical signals is monitored and is processed in this variation by Hall chip.Transfer out by wire harness.
Good effect of the present utility model: eliminate the response delay bringing because of efp mechanics and sensor joint gap completely, realize the real-time response of sensor output signal and the action of driver's step on the accelerator; Eliminate Das Gaspedal start the to reset error signal of moment and produce, reduce the correlated error of sensor output electrical signals and standard signal.
