Abstract
The invention discloses an automobile electronic accelerator pedal. A resetting mechanism is arranged between a pedal arm and a pedal base; the resetting mechanism consists of two concentrically sleeved pressure springs, namely a pressure spring A and a pressure spring B in a concentrically sleeved structure; the diameter of the pressure spring A is greater than that of the pressure spring B; the pressure spring A is sleeved outside the pressure spring B; and the pressure spring A and the pressure spring B eject the pedal arm and the pedal base. When the automobile electronic accelerator pedal disclosed by the invention is adopted, a concentric pressure plate resetting mechanism solves the fatigue failure problem of the torsional spring in the prior art and improves the service life and reliability of the electronic accelerator pedal; the unique lever type pedal arm reduces the breakthrough force and retaining force of a pedal; the combination of the pedal arm and the two concentrically sleeved pressure springs makes the pedal more convenient and reliable; and the automobile electronic accelerator pedal has the characteristics of simple structure, convenience for manufacturing and installation, high usability, safety and reliability.
Description
Technical field
The present invention relates to a kind of electronic accelerator pedal of automobile, belong to the electric accelerator pedal for vehicle product technical field.
Background technology
At present in medium-to-high grade type car; Its employed Das Gaspedal generally is to adopt the electronic type Das Gaspedal, and this efp is quick on the draw with it; In medium-to-high grade type car, obtained general application in recent years; But, also expose existing defective on its structure along with the growth of period of service: the one, the Bringing-back mechanism of existing electronic type Das Gaspedal is the return mechanism that adopts the torsion spring structure, its torsion spring of the return mechanism of torsion spring structure is easy to generate fatigue failure; Influence the reliability that efp uses, thereby can influence traveling security; The 2nd, pedal adopts straight-bar type pedal arm structure, and the pedal of this structure in use breaks through power and confining force is bigger, and pedal is relatively required great effort.
Summary of the invention
The present invention provides a kind of a kind of electronic accelerator pedal of automobile of novelty, adopts concentric pressing spring return structure and curved lever formula pedal arm structure technology, to prevent the efp inefficacy and to reduce the breakthrough power of pedal and the purpose of confining force.
The technical scheme that the present invention adopts is:
A kind of electronic accelerator pedal of automobile comprises: pedal arm, pedal pedestal, Bringing-back mechanism, electronics package; Between described pedal arm and pedal pedestal, be provided with a Bringing-back mechanism; Bringing-back mechanism is made up of two pressing springs that are concentricity suit, promptly is concentricity sleeve structure by pressing spring A, pressing spring B and constitutes, and the diameter of pressing spring A is greater than the diameter of pressing spring B; Pressing spring A is set in the outside of pressing spring B, pressing spring A, pressing spring B roof pressure pedal arm, pedal pedestal.
Pedal arm is a curved arm lever formula structure, is provided with the crank throw shape structure of crooked protrusion to the left or to the right at the medium position of pedal arm.
Electronics package is a modular construction.
Beneficial effect of the present invention is:
Owing to adopted a kind of electronic accelerator pedal of automobile of the present invention; The torsion spring return structure that concentric pressing spring return mechanism has overcome prior art is easy to generate the problem of fatigue failure; The service life and the reliability of efp have been improved; Unique lever pedal arm makes the breakthrough power and the confining force of pedal reduce, and is used with two concentric pressing springs; Make pedal more easily more reliable, a kind of electronic accelerator pedal of automobile of the present invention has: characteristics simple in structure, that manufacturing is easy for installation, in-use performance is good, safe and reliable.

Among Fig. 4,5: pedal arm 1, pedal pedestal 2, pressing spring A3, pressing spring B4.
The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5.
A kind of electronic accelerator pedal of automobile comprises: pedal arm 1, pedal pedestal 2, pressing spring A3, pressing spring B4 structure.
Pressing spring A3, pressing spring B4 constitute the Bringing-back mechanism of efp.
Between pedal arm 1 and pedal pedestal 2, be provided with a Bringing-back mechanism; Bringing-back mechanism is made up of two pressing springs that are concentricity suit; Promptly being concentricity sleeve structure by pressing spring A3, pressing spring B4 constitutes; The diameter of pressing spring A3 is greater than the diameter of pressing spring B4, and pressing spring A3 is set in the outside of pressing spring B4, pressing spring A3, pressing spring B4 roof pressure pedal arm 1, pedal pedestal 2.
Pedal arm 1 is a curved arm lever formula structure, is provided with the crank throw shape structure of crooked protrusion to the left or to the right at the medium position of pedal arm 1.
Electronics package is a modular construction.
Basic functional principle:
Press Fig. 4, shown in Figure 5, the pressing spring B4 that diameter is little is set among the big pressing spring A3 of diameter, then two springs is same center structure and is installed between pedal arm 1 and the pedal pedestal 2, constitutes the Bringing-back mechanism of a pedal arm 1.
Press Fig. 1, Fig. 2, Fig. 3, shown in Figure 4 then; Detail assemblys such as pedal arm 1, pedal pedestal 2, Bringing-back mechanism, dual output position transduser are become electronic accelerator pedal of automobile; Then electronic accelerator pedal of automobile is installed on the vehicle, efp promptly can use behind the road that Connects Power.Pedal arm is trampled under the effect with retracing spring pin, can be in different position of rotation; The variation of sensor sensing position and export the electric signal of a variation, displacement strengthens, and electric signal strengthens; Displacement diminishes, and electric signal diminishes.The electric signal of this variation inputs to ECU, and then the control throttle, reaches the purpose of acceleration-deceleration.
Owing to adopted the Bringing-back mechanism of two pressing spring structures, more reliable and secure than torsion spring Bringing-back mechanism, the Bringing-back mechanism indefatigability lost efficacy; Owing to adopted the pedal arm of curved arm lever formula structure, make the more reasonable stress of pedal arm, pedal is lighter; Owing to adopted the sensor of modular construction, make electronics package more safe and reliable, not fragile, installation and maintenance are convenient.Having eliminated various hidden dangers, guaranteed traveling security, is a kind of electronic accelerator pedal of automobile of function admirable safety.
