Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0020] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0021] In the technical scheme, the automobile suspension type electronic throttle pedal with the noise reduction effect comprises a pedal arm 1 and a base 3, the end of the pedal arm 1 is inserted into the base 3, a rotating shaft 4 is assembled in the inside of the base 3, and the end of the pedal arm 1 is hinged to the rotating shaft 4; a limiting body 13 is assembled on the upper end of the rear inside of the base 3, a spring seat 17 is assembled on the lower end of the rear inside of the base 3, and a compression spring is assembled between the spring seat 17 and the limiting body 13; a buffer block 2 is assembled on the upper side of the end of the pedal arm 1, and the buffer block 2 is clamped in the inner groove of the base 3; a friction block 18 is assembled on the front end of the pedal arm 1, and the friction block 18 is clamped in the inside of the base 3; the compression spring comprises an outer compression spring 14 and an inner compression spring 15, the outer compression spring 14 is sleeved on the outside of the inner compression spring 15, a throttle gasket 16 is assembled on the bottom end of the outer compression spring 14 and the inner compression spring 15, and the throttle gasket 16 is assembled on the spring seat 17.

[0022] The end of the pedal arm 1 is arranged in the base 3 in the form of insertion, the connecting mode facilitates the corresponding rotating operation of the pedal arm in the base, and provides a basis for realizing the function of the throttle pedal subsequently.

[0023] The limiting body 13 assembled on the upper end of the rear inside of the base 3 can limit the upper limit position of the rotation of the pedal arm, and prevent the pedal arm from being excessively rotated and damaging the related components. The spring seat 17 assembled on the lower end of the rear inside of the base 3 provides a stable supporting basis for the compression spring. The compression spring is arranged between the spring seat 17 and the limiting body 13, and mainly provides the elastic force for the reset of the pedal arm 1. When the driver steps on the pedal arm 1, the compression spring is compressed, and stores the elastic potential energy; when the driver releases the pedal arm 1, the compression spring releases the elastic potential energy, and pushes the pedal arm 1 to reset.

[0024] The compression spring is composed of an outer compression spring 14 and an inner compression spring 15. The outer compression spring 14 is sleeved outside the inner compression spring 15. This double-layer spring structure can provide more suitable and stable spring force characteristics. The bottom ends of the outer compression spring 14 and the inner compression spring 15 are equipped with a throttle gasket 16. The throttle gasket 16 is equipped on a spring seat 17. On the one hand, the throttle gasket 16 can play a buffering role, reduce the rigid contact between the spring and the spring seat 17, and reduce wear and noise. On the other hand, it also helps to uniformly disperse the pressure of the spring, ensuring the stability of the spring operation.

[0025] The end of the pedal arm 1 is equipped with a buffer block 2, which is clamped in the inner groove of the base 3. When the pedal arm 1 rotates to a certain position and contacts the base 3, the buffer block 2 can play a buffering role, avoiding direct rigid collision between the pedal arm 1 and the base 3, thereby reducing the generation of noise, and also protecting the relevant parts of the pedal arm 1 and the base 3, prolonging their service life.

[0026] The front end of the pedal arm 1 is equipped with a friction block 18, which is clamped inside the base 3. The friction block 18 can increase the friction between the pedal arm 1 and the base 3, so that the pedal arm 1 can be more stably maintained at the set position during rotation, avoiding accidental rotation of the pedal arm 1 due to factors such as vibration during vehicle driving, affecting the accuracy of throttle control.

[0027] In some technical solutions, the outer part of the rotating shaft 4 is sleeved with a magnetic ring 5 and a magnetic sheet 6. The outer part of the base 3 is equipped with an electronic box shell 7. The electronic box shell 7 is equipped with a pin 12.

[0028] The outer part of the rotating shaft 4 is sleeved with a magnetic ring 5 and a magnetic sheet 6. When the pedal arm 1 rotates around the rotating shaft 4, the magnetic ring 5 and the magnetic sheet 6 will rotate together. The outer part of the base 3 is equipped with an electronic box shell 7, which is used to accommodate and protect the internal electronic components. The pin 12 on the electronic box shell 7 facilitates connection with other circuit systems of the vehicle, realizing signal transmission. The outer wall of the electronic box shell 7 is equipped with an electronic box cover 10. The electronic box cover 10 and the electronic box shell 7 are connected through a bolt body 16. This connection method is convenient for opening the electronic box cover 10 when needed, and for repairing, maintaining or replacing the internal electronic components.

[0029] In some technical solutions, the inside of the electronic box shell 7 is equipped with a circuit board 9, and the circuit board 9 is equipped with a Hall chip 8.

[0030] The inside of the electronic box shell 7 is equipped with a circuit board 9, and the circuit board 9 is equipped with a Hall chip 8. When the magnetic ring 5 and the magnetic sheet 6 rotate with the pedal arm 1, the change of the surrounding magnetic field will be caused, the Hall chip 8 can sense the change of the magnetic field and convert it into an electric signal. The electric signal is transmitted to the electronic control unit (ECU) of the vehicle through the connecting components such as the pin 12, and the ECU judges the position of the accelerator pedal and the operation intention of the driver according to the received signal, and then controls the opening degree of the throttle valve of the engine, so as to realize the precise control of the power output of the engine.

[0031] In some technical solutions, the bottom end of the bolt body 11 is provided with a circular groove 111, the bottom end of the circular groove 111 is provided with a bolt rod 113, the outer upper end of the bolt rod 113 is provided with a fixing ring 116, and the circumferential surface of the bolt rod 113 is sleeved with an annular pressing piece 115, a spring 117 and an annular rubber sheet 112.

[0032] The bottom end of the bolt body 11 is provided with a circular groove 111, which is designed to better cooperate with other components, such as accommodating a connecting piece of a specific shape, enhancing the stability of the connection. The bottom end of the circular groove 111 is provided with a bolt rod 113, which is used for threaded connection with the components to be fixed. The outer upper end of the bolt rod 113 is provided with a fixing ring 116, which can play a role in positioning and limiting the position of other components. The circumferential surface of the bolt rod 113 is sleeved with an annular pressing piece 115, a spring 117 and an annular rubber sheet 112, the annular pressing piece 115 can uniformly transmit the pressure of the spring 117 and the annular rubber sheet 112 to the connected components during the tightening of the bolt; the spring 117 can provide certain elastic buffer to prevent damage to the components due to excessive tightening force of the bolt, and at the same time, during the driving of the vehicle, due to factors such as vibration, the spring 117 can play a certain self-adaptive adjustment role to maintain the stability of the connection; the annular rubber sheet 112 can play a role in sealing and shock absorption, preventing dust, water vapor and the like from entering the connection part, and reducing noise caused by vibration.

[0033] In some technical solutions, the upper end edge of the annular rubber sheet 112 is provided with an extrusion block 114, the outer wall of the bolt body 11 is provided with a circular arc surface 118, and the surface of the circular arc surface 118 is provided with anti-skid lines.

[0034] The upper end edge of the annular rubber sheet 112 is provided with an extrusion block 114, which can better transmit pressure to the surrounding when the annular rubber sheet 112 is subjected to pressure, thereby enhancing the sealing and damping effects. The outer wall of the bolt body 11 is provided with a circular arc surface 118, and the surface of the circular arc surface 118 is provided with anti-skid lines. The circular arc surface 118 can reduce the scratching of other components during assembly or use, and the anti-skid lines can facilitate the tightening or loosening of the bolt by the operator, increase the friction, and prevent slipping.

[0035] In some technical solutions, the top rear side of the pedal arm 1 is equipped with an anti-skid protrusion 19, and the outer wall of the anti-skid protrusion 19 is uniformly and equidistantly provided with protrusions 20.

[0036] The top rear side of the pedal arm 1 is equipped with an anti-skid protrusion 19, and the outer wall of the anti-skid protrusion 19 is uniformly and equidistantly provided with protrusions 20. The anti-skid protrusion 19 and the protrusions 20 are mainly designed to increase the friction between the driver's feet and the pedal arm, prevent the feet from slipping during the process of stepping on the accelerator pedal due to vehicle vibration, sweating, etc., and affect the control accuracy of the accelerator pedal, thereby affecting the driving safety and the power control of the vehicle

[0037] In some technical solutions, the anti-skid protrusion 19 is internally provided with a filling cavity 21, and the filling cavity 21 is internally provided with an elastic member 22.

[0038] The anti-skid protrusion 19 is internally provided with a filling cavity 21, and the filling cavity 21 is internally provided with an elastic member 22. When the driver steps on the pedal arm, the feet exert pressure on the anti-skid protrusion 19, and the elastic member 22 will elastically deform in the filling cavity 21. This elastic deformation can further increase the friction between the anti-skid protrusion 19 and the feet, because the deformation of the elastic member 22 can make the anti-skid protrusion 19 better fit the feet. On the other hand, the elastic buffering effect of the elastic member 22 can reduce the fatigue of the driver's feet, especially during long-time driving, frequent stepping on the accelerator pedal, and the buffering effect can make the driver's feet feel more comfortable.

[0039] Working process and principle: when the driver steps on the pedal arm 1, the pedal arm 1 rotates around the rotating shaft 4, and the end part is pressed downward into the base 3, compressing the compression springs (outer compression spring 14 and inner compression spring 15) between the spring seat 17 and the limiting body 13. In this process, the buffer block 2 on the upper side of the end part of the pedal arm 1 contacts the inner groove of the base 3, playing a buffering and damping role, reducing the collision noise; the friction block 18 at the front end ensures the stable rotation of the pedal arm 1 in the base 3, avoiding position deviation due to vibration.

[0040] Meanwhile, the magnetic ring 5 and the magnetic sheet 6 outside the rotating shaft 4 are sleeved and rotate with the pedal arm 1, causing the change of the surrounding magnetic field. The Hall chip 8 on the circuit board 9 in the electronic box shell 7 converts the change of the magnetic field into an electric signal, which is transmitted to the vehicle electronic control unit (ECU) through the pin 12 on the electronic box shell 7. The ECU judges the position of the accelerator pedal and the intention of the driver according to the received electric signal, and then controls the opening degree of the engine throttle, and adjusts the power output of the engine.

[0041] When the driver releases the pedal arm 1, the compression spring releases the elastic potential energy and pushes the pedal arm 1 to reset. During this period, the accelerator pad 16 reduces the rigid contact between the spring and the spring seat 17, reducing wear and noise. The anti-skid convex strip 19 at the top rear side of the pedal arm 1 and the internal elastic member 22 increase the friction and provide elastic buffering during the stepping process, improving the driving comfort and operation stability.
