[0002] In today's rapidly developing transportation industry, more and more vehicles are appearing in people's daily lives, and automobiles have become the mainstream means of transportation. Electronic throttle pedals are increasingly widely used in vehicles. These pedals output corresponding electrical signals based on the degree of pedal pressure to control the throttle opening. For example, there is an invention patent with application number CN201010600449.3 entitled "Electronic Throttle Pedal with High Linear Output Signal." This type of electronic throttle pedal has the same structure as most others, using a hinge shaft for connection. However, the friction of the hinge shaft is not high enough, resulting in limited hysteresis and leaving room for improvement. Utility Model Content

The rotating support and the base, as well as the rotating support and the rotating arm, are both designed with wear-resistant structures to increase friction.

[0005] The aforementioned non-contact floor pedal structure also has the following feature: a pad is provided at one end of the base corresponding to both sides of the push rod, and the pad is in contact with the curved surface of the base.

[0006] The aforementioned non-contact floor pedal structure also features the following characteristic: the base is provided with an mounting groove for mounting the pad, the shape of which is adapted to the outer shape of the pad, the mounting groove includes a first part and a second part connected together, the pad is a strip block structure, the longitudinal cross-section of the pad is mushroom-shaped, the longitudinal cross-section of the pad includes a mushroom head and a mushroom stem connected together, the mushroom head is inserted into the first part, one end of the mushroom stem is inserted into the second part, and the other end of the mushroom stem extends out of the second part and can contact the push rod.

[0007] The aforementioned non-contact floor pedal structure also features the following characteristic: the mounting groove is configured as a slot, the slot has an insertion side, and a limiting block is provided on the base facing the insertion side to achieve lateral limiting of the pad block.

[0008] The aforementioned non-contact floor pedal structure also features a wear-resistant part on the mushroom head.

[0013] The positive effects of the above technical solution are: This utility model provides a non-contact floor-type pedal structure. All hinged positions are rotatably connected using an arc-shaped structure, or some structures are rotatably connected using an arc-shaped structure. When the pedal is stepped on, the pedal applies downward pressure to the push rod. The push rod presses down one end of the rotating support, which in turn applies downward pressure to the elastic component. The elastic component then applies downward pressure to the other end of the rotating arm, causing one end of the rotating arm to tilt upward. The rotating arm then applies an upward reaction force to the other end of the rotating support, thus delaying the downward pressure and rotation of the pedal, creating resistance. The greater the pressure on the elastic component, the greater the friction between the outer and inner arc surfaces, and the greater the friction between the arc groove and the friction surface, resulting in greater resistance when the pedal is stepped on.

[0014] The pad acts as a buffer, reducing the impact noise when stepping. At the same time, the pad and the base have curved contact. The pedal, push rod and rotating support are actually a linkage mechanism. During the rotation of the push rod, the curved contact can achieve a better follow-up effect, making the whole action smoother. Attached Figure Description

[0020] Please see Figures 1 to 11The present invention discloses a non-contact floor pedal structure, which includes: a base 1, a pedal 2, a push rod 3, a rotating support 4, a rotating arm 5, an elastic component 6, a pad 7, and a sensor component 8. One end of the pedal 2 is rotatably connected to the base 1, the other end of the pedal 2 is rotatably connected to one end of the push rod 3, the other end of the push rod 3 is rotatably connected to one end of the rotating support 4, the other end of the rotating support 4 is rotatably connected to the base 1, one end of the rotating arm 5 is rotatably connected to the other end of the rotating support 4, and the other end of the rotating arm 5 is provided with an elastic component 6, which is sandwiched between the rotating support 4 and the rotating arm 5.

[0021] Optionally, in this embodiment, the base 1 is a shell-like structure. The pedal 2 is located outside the base 1, part of the push rod 3 is located outside the base 1, and the other part of the push rod 3 is located inside the base 1. The rotating support 4, rotating arm 5, elastic component 6, and pad 7 are all located inside the base 1, and the sensor assembly 8 is located outside the base 1.

[0022] Optionally, in this embodiment, as Figure 2 As shown, the pedal 2 and the base 1 are rotatably connected by a rubber strip 9, which has a certain degree of flexibility to achieve the rotatable connection. Of course, in other embodiments, the pedal 2 and the base 1 can be hinged together by a shaft.

[0023] Optionally, in this embodiment, the other end of the pedal 2 is rotatably connected to one end of the push rod 3 through an arc-shaped structure. Of course, in other embodiments, the pedal 2 and the push rod 3 can be hinged together by a shaft.

[0024] Optionally, in this embodiment, the other end of the push rod 3 is rotatably connected to one end of the rotating support 4 through an arc-shaped structure. Of course, in other embodiments, the other end of the push rod 3 and one end of the rotating support 4 can be hinged together by a shaft.

[0025] Optionally, in this embodiment, one end of the rotating arm 5 is rotatably connected to the other end of the rotating support 4 through an arc-shaped structure. Of course, in other embodiments, the other end of the push rod 3 can be hinged to one end of the rotating support 4 through a shaft.

[0026] Optionally, in this embodiment, the rotating support 4 and the base 1 are rotatably connected by an arc-shaped structure. Of course, in other embodiments, the other end of the push rod 3 and one end of the rotating support 4 can be hinged by a shaft.

[0027] Preferably, in this embodiment, such as Figure 2As shown, the rotating support 4 and the base 1, as well as the rotating support 4 and the rotating arm 5, are rotatably connected by an arc-shaped structure. The rotating support 4 and the base 1, as well as the rotating support 4 and the rotating arm 5, are both designed with wear-resistant structures to increase friction.

[0028] Specifically, such as Figure 5 and Figure 6 As shown, the other end of the rotating support 4 is provided with an outer arc-shaped surface 41, and the base 1 is provided with an inner arc-shaped surface 11. The outer arc-shaped surface 41 and the inner arc-shaped surface 11 cooperate to achieve a rotatable connection. Optionally, both the outer arc-shaped surface 41 and the inner arc-shaped surface 11 are made of wear-resistant material. The other end of the rotating support 4 is provided with an arc-shaped groove 43, and one end of the rotating arm 5 is provided with an arc-shaped surface 51. The arc-shaped surface 51 and the arc-shaped groove 43 cooperate to achieve a rotatable connection. Optionally, both the arc-shaped surface 51 and the arc-shaped groove 43 are made of wear-resistant material. Optionally, as... Figure 9 As shown, in this embodiment, a friction surface 42 for increasing friction is provided on the outer arc-shaped surface 41. The friction surface 42 cooperates with the inner arc-shaped surface 11, as follows: Figure 9 As shown, the friction surface 42 is a grid-like arc surface protruding from the arc-shaped surface. In this embodiment, the friction surface 42, the arc-shaped surface 51, and the arc-shaped groove 43 are all made of wear-resistant material (the outer arc-shaped surface 41 does not need to be made of wear-resistant material) to increase friction. Figure 2 As shown, when pedal 2 is pressed, pedal 2 exerts downward pressure on push rod 3. Push rod 3 presses down, causing one end of rotating support 4 to press down. Rotating support 4 exerts downward pressure on elastic component 6, and elastic component 6 exerts downward pressure on the other end of rotating arm 5, causing one end of rotating arm 5 to tilt upward. Rotating arm 5 exerts an upward reaction force on the other end of rotating support 4, which can delay the downward pressing and rotation of pedal 2, thus creating resistance to pedal 2. The more the elastic component 6 is compressed, the greater the friction between the outer arc surface 41 and the inner arc surface 11, and the greater the friction between the arc groove 43 and the friction surface 42, resulting in greater resistance when pedal 2 is pressed.

[0029] Preferably, in this embodiment, such as Figure 2 As shown, in this embodiment, the pedal 2 and push rod 3, the push rod 3 and rotating support 4, and the rotating arm 5 and rotating support 4 are all rotatably connected by an arc-shaped structure. Optionally, in other embodiments, at least one of the pedal 2 and push rod 3, the push rod 3 and rotating support 4, and the rotating arm 5 and rotating support 4 may be rotatably connected by an arc-shaped structure.

[0030] Optionally, such as Figure 3 and Figure 10As shown, in this embodiment, a groove 53 is provided at the other end of the rotating arm 5. A portion of the elastic component 6 is placed in the groove 53, and the other portion extends out of the groove 53. The elastic component 6 includes a first spring 61, a second spring 62, and a spacer. The first spring 61 is disposed within the second spring 62, and the spacer is disposed between the first spring 61 and the second spring 62. Optionally, the spacer can be a sponge 63 or other flexible structure. The first spring 61 and the second spring 62 are supported between the rotating arm 5 and the rotating support 4. The first spring 61 and the second spring 62 can press down the rotating arm 5 when the pedal 2 is stepped on, and reset the pedal 2 through the rotating support 4 when the pedal 2 is released. To avoid abnormal noise caused by collision between the first spring 61 and the second spring 62, a spacer is specially provided between the first spring 61 and the second spring 62, and the spacer is located between the outer wall surface of the first spring 61 and the inner wall surface of the second spring 62. This can also prevent the first spring 61 from shifting and ensure the stability of the first spring 61 and the second spring 62. Optionally, the spacer can be a sponge 63. Alternatively, in other embodiments, the elastic component 6 includes a spring and a flexible rod disposed in a groove, which can be integrally designed with the rotating arm 5.

[0031] like Figure 1 and Figure 11 As shown, (where, Figure 11 (Only one cover of the housing 81 of the sensor assembly 8 has been removed) The sensor assembly 8 is set on one side of the base 1 and is set in correspondence with the magnet 10 set on the rotating support 4.

[0032] Optionally, in this embodiment, the sensor assembly 8 includes a housing 81, a circuit board 82, and a Hall sensor (not shown in the figure). One side of the housing 81 is mounted on one side of the base 1, the circuit board 82 is mounted inside the housing 81, and the Hall sensor is mounted on the circuit board 82 and correspondingly positioned opposite the magnet 10. When the pedal 2 is pressed, the rotating support 4 rotates, and the magnet 10 also rotates, causing a change in the magnetic field. The angle of rotation of the magnetic field is proportional to the angle of rotation of the pedal 2. The Hall sensor senses the change in the magnetic field and outputs a corresponding voltage signal, thereby controlling the throttle opening.

[0033] Optionally, such as Figure 5 As shown, the magnet 10 is disposed on the outer side of the other end of the rotating support 4. Optionally, in this embodiment, the magnet 10 and the rotating support 4 are injection molded. Of course, in other embodiments, the magnet 10 is detachably mounted on the rotating support 4.

[0034] Optionally, in this embodiment, as Figure 2 , Figure 4 , Figures 6 to 8As shown, a pad 7 is provided on each side of the push rod 3 at one end of the base 1, and the pad 7 contacts the curved surface of the base 1. Specifically, the base 1 has an installation groove 12 for installing the pad 7. The shape of the installation groove 12 is adapted to the shape of the pad 7. The installation groove 12 includes a first part 121 and a second part 122 connected together. The pad 7 is a strip block structure. The longitudinal cross-section of the pad 7 is mushroom-shaped. The longitudinal cross-section of the pad 7 includes a mushroom head 71 and a mushroom stem 72 connected together. The mushroom head 71 is inserted into the first part 121, and one end of the mushroom stem 72 is inserted into the second part 122. The other end of the mushroom stem 72 extends out of the second part 122 and can contact the push rod 3. As shown in the figure... Figure 2 As shown, each pad 7 on the base 1 has a mounting slot 12.

[0035] Furthermore, as a preferred embodiment, such as Figure 6 and Figure 7 As shown, the mounting slot 12 is configured as a slot, and the slot has a socket side 123, such as... Figure 8 As shown, a limiting block 13 is provided on the base 1 facing the socket side 123 to limit the lateral movement of the pad block 7. In fact, as... Figure 6 As shown, in this embodiment, the slot has three interconnected inner sidewalls. The inner sidewall corresponding to the insertion side 123 is used to achieve the lateral mounting and locking of the pad 7. The inner sidewall corresponding to the insertion side 123, together with the limiting block 13, limits the pad 7. The mushroom rod 72 extends longitudinally out of the slot and can contact the pad 7 to achieve a buffering effect on the push rod 3. In this embodiment, the pad 7 plays a buffering role, which can reduce the impact noise when stepping on it. At the same time, the pad 7 has a curved contact with the base 1. The pedal 2, push rod 3, rotating support 4, and rotating arm are actually a linkage mechanism. During the rotation of the push rod 3, the curved contact can achieve a better follow-up effect, making the whole action smoother.

[0036] Preferably, the mushroom-shaped head 71 is provided with a wear-resistant portion. Optionally, the wear-resistant portion can be raised dots or textured surfaces. The wear-resistant portion increases the cushioning effect.

[0037] This utility model provides a non-contact floor pedal structure in which all hinge points are rotatably connected using an arc-shaped structure, or only some points are rotatably connected using an arc-shaped structure. When the pedal 2 is stepped on, the pedal 2 applies downward pressure to the push rod 3. The push rod 3 presses down, causing one end of the rotating support 4 to press down. The rotating support 4 applies downward pressure to the elastic component 6, and the elastic component 6 applies downward pressure to the other end of the rotating arm 5, causing one end of the rotating arm 5 to tilt upward. The rotating arm 5 applies an upward reaction force to the other end of the rotating support 4, which can delay the downward pressure and rotation of the pedal 2, thus creating resistance to the pedal 2. The more the elastic component 6 is compressed, the greater the friction between the outer arc surface 41 and the inner arc surface 11, and the greater the friction between the arc groove 43 and the friction surface 42, resulting in greater resistance when the pedal 2 is stepped on.

[0038] The pad 7 serves as a buffer, reducing the impact noise when stepping. At the same time, the pad 7 and the base 1 have curved contact. The pedal 2, push rod 3 and rotating support 4 are actually a linkage mechanism. During the rotation of push rod 3, the curved contact can achieve a better follow-up effect, making the whole action smoother.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
