[0010] Beneficial effects:
[0011] 1. The electronic accelerator pedal structure changes the large plane contact mode between the base and the connecting rod in the traditional pedal to a boss-type small plane contact mode, thereby reducing the contact area between the base and the connecting rod, thereby reducing the noise generated when the base and the connecting rod contact, and also avoiding the false impression of vehicle failure, ensuring driving safety;
[0012] 2. A groove is provided in the middle of the first boss on the base to open a gap in the originally closed cavity, so as to prevent the sound from propagating in the cavity and causing resonance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0023] Example
[0024] Reference Figures 1 to 5 The present embodiment provides a suspended low-noise electronic throttle pedal structure, including a base 1, a connecting rod 2 is rotatably arranged on the base 1, a spring 3 is fixedly arranged at the bottom of the connecting rod 2, a pedal 4 is fixedly arranged at one end of the connecting rod 2 away from the base 1, a first boss 5 is arranged in the upper cavity of the base 1, a second boss 6 matched with the first boss 5 is arranged at the front of the connecting rod 2, a limited surface 7 is arranged at the lower part of the base 1, and a third boss 8 matched with the limited surface 7 is arranged at the bottom of the connecting rod 2 to reduce noise.
[0025] The base 1 is used as the installation base of the electronic accelerator pedal and is fixedly installed on the vehicle body. A connecting rod 2 is rotatably installed on the base 1. A spring 3 is fixedly installed at the bottom of the connecting rod 2. The end of the spring 3 away from the connecting rod 2 is fixedly connected to the base 1, and a pedal 4 is fixedly installed at the end of the connecting rod 2 away from the base 1. In the initial state, the connecting rod 2 is subjected to the elastic force of the spring 3, so that the connecting rod 2 is in an upward moving state, and the front part of the connecting rod 2 contacts the upper part of the front side of the base 1 to form an initial position limiting surface 7 to play a limiting role. In this embodiment, a first boss 5 is provided in the upper cavity on the front side of the base 1, and a second boss 6 matching the first boss 5 is provided at the front of the connecting rod 2. The initial position limit surface 7 of the plane is changed into a small boss-like plane, which reduces the contact area between the base 1 and the connecting rod 2, thereby reducing the noise; when a downward extrusion force is applied to the pedal 4, the connecting rod 2 squeezes the spring 3 until the bottom of the connecting rod 2 contacts the lower part of the base 1 to form a full-load position limit surface 7. In this embodiment, a limiting surface 7 is provided at the lower part of the base 1, and a third boss 8 is provided at the bottom of the connecting rod 2 to match the limiting surface 7. The third boss 8 is in the shape of a long strip, so as to change the full-load position limit surface 7 of the original large plane into a small long boss-like plane, thereby reducing the contact area between the base 1 and the connecting rod 2, thereby reducing the noise and ensuring driving safety.
[0026] Furthermore, a groove 9 is formed in the middle of the first boss 5 .
[0027] Since a suspended pedal structure almost always forms a hollow chamber inside, in a closed environment, sound and air will rebound repeatedly in the environment to cause vibration. This embodiment provides a groove 9 on the first boss 5 of the base 1, which can effectively open a gap in the closed environment to avoid cavity vibration and further reduce noise. It should be noted that the size of the groove 9 can be controlled within a suitable range according to actual usage conditions to avoid sharp collision sounds caused by too small a contact surface.
[0028] Furthermore, the width of the second boss 6 is smaller than the width of the first boss 5 , and the width of the third boss 8 is smaller than the width of the limiting surface 7 .
[0029] In this embodiment, the width of the second boss 6 is designed to be smaller than the width of the first boss 5, and the width of the third boss 8 is designed to be smaller than the width of the limiting surface 7, thereby further reducing the contact area between the connecting rod 2 and the base 1, thereby further reducing the noise generated when the connecting rod 2 contacts the base 1.
[0030] Furthermore, the first boss 5 and the limiting surface 7 are both arranged in the central area of the base 1 , and the second boss 6 and the third boss 8 are both arranged in the central area of the connecting rod 2 .
[0031] In this embodiment, the first boss 5 and the limiting surface 7 are both arranged in the central area of the base 1, and the second boss 6 and the third boss 8 are both arranged in the central area of the connecting rod 2, so that the second boss 6 can better cooperate with the first boss 5 and the third boss 8 can better cooperate with the limiting surface 7, so as to achieve the effect of uniform force.
[0032] Furthermore, the first boss 5 , the second boss 6 and the third boss 8 are all made of rubber.
[0033] In this embodiment, the first boss 5 , the second boss 6 and the third boss 8 are made of rubber material, so as to further reduce the noise generated when the base 1 contacts the connecting rod 2 .
[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
