[0004] In the above application, through the mutual cooperation between the positioner, accelerator pull rod and other components, it is difficult to solve the problem that the pedal may be stuck or stuck when stepping on the pedal, which may cause the driver to experience a not smooth experience during acceleration, affecting the comfort and safety of driving, and needs to be improved. Utility model content

[0005] In order to overcome the above defects, the embodiment of the utility model provides an electronic accelerator pedal for automobile, which solves the technical problem that the cabin temperature cannot be effectively maintained in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides an electronic accelerator pedal for automobiles, including a mounting plate. A mounting groove is provided on the top of the mounting plate. An anti-jamming component is provided on the top of the mounting plate. The anti-jamming component includes a sensor.

One end of the connecting rod is fixedly connected to a foot pedal. A control box is fixedly connected to the side of the sensor. A movable plate is slidably connected to the inner wall of the control box. A fixed plate is fixedly connected to the inner wall of the control box. A push rod is fixedly connected to the top of the movable plate. The end of the push rod away from the movable plate extends through the top of the control box.

[0007] For example, in at least one embodiment of the present invention, an electronic accelerator pedal for automobiles is provided, which further includes: two fixed plates are provided and are symmetrical to each other along the vertical central axis of the movable plate; a contact plate is fixedly connected to the end of the push rod away from the movable plate; the design of the contact plate increases the contact area and facilitates the squeezing of the push rod.

[0008] A limit rod is fixedly connected to the inner wall of the control box. The end of the limit rod away from the control box passes through the bottom of the moving plate. The design of the limit rod helps to limit the movement trajectory of the moving plate and prevent the movement trajectory of the moving plate from deviating.

[0009] A spring is fixedly connected to the inner wall of the control box. The end of the spring away from the control box is fixedly connected to the bottom of the moving plate. The design of the spring is conducive to the automatic reset when the moving plate is not squeezed.

[0010] The end of the oil outlet pipe furthest from the control box is located on the side of the connecting rod. A plug is provided on the side of the oil outlet pipe, and a connecting pipe opening is provided on the side of the sensor. The plug is designed to block the oil outlet of the oil outlet pipe when lubricant is not needed, thus preventing continuous oil leakage.

[0011] A short pipe runs through the side of the control box, and a storage tank runs through the end of the short pipe away from the control box. A replenishment pipe runs through the top of the storage tank. The design of the replenishment pipe facilitates the replenishment of oil in the storage tank.

[0012] According to another aspect, at least one embodiment of the present invention also provides an electronic accelerator pedal for automobiles, comprising: a heat dissipation assembly disposed on the top of the mounting plate, the heat dissipation assembly including a pressing rod, one end of the pressing rod being fixedly connected to the outer wall of a push rod, a vertical rod being fixedly connected to the side of the mounting plate, a rotating shaft being rotatably connected to the side of the vertical rod, fan blades being fixedly connected to the circumferential surface of the rotating shaft, and an inclined rod being fixedly connected to the circumferential surface of the rotating shaft, wherein the fan blades are driven to rotate to generate wind force to blow air and cool the sensor.

[0013] For example, in at least one embodiment of the present invention, an electronic accelerator pedal for automobiles further includes: the fan blade is located on the side of the sensor, a short rod is fixedly connected to the side of the vertical rod, and a housing is fixedly connected to one end of the short rod.

[0014] The fan blades and the rotating shaft are located on the inner wall of the outer casing. The tilting rod is located on the displacement trajectory of the extrusion rod. Several fan blades are arranged and arrayed circumferentially on the circumferential surface of the rotating shaft. This design is beneficial for the tilting rod to be extruded when the extrusion rod moves.

[0015] A torsion spring is fixedly connected to the circumferential surface of the rotating shaft. The end of the torsion spring away from the rotating shaft is fixedly connected to the side of the outer shell. A protective grille is fixedly connected to the side of the outer shell. The design of the torsion spring is conducive to self-resetting when the rotating shaft is not squeezed.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation between the control box, push rod, oil outlet pipe, moving plate and other components inside the anti-jamming component, friction can be reduced at the rotating part of the connecting rod by lubricating it, so as to avoid jamming or sticking when pressing the pedal. This is very important for electronic accelerator pedals, because if the friction is too great or there is jamming, the driver may encounter an unsmooth experience during acceleration, which will affect the comfort and safety of driving. Regular lubrication can reduce wear between components, reduce the failure rate and increase the overall reliability of the system.

[0018] 2.

Electronic accelerator pedals usually involve electronic sensors and related circuits. These electronic components generate heat during use. Through this heat dissipation mechanism, the temperature can be effectively reduced, preventing electronic components from malfunctioning due to overheating, thereby extending the service life of the electronic sensor and pedal system and improving system stability and reliability.

Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, an electronic accelerator pedal for automobiles according to an embodiment of the present invention is illustrated, including a mounting plate 1. The top of the mounting plate 1 has a mounting groove 2. An anti-jamming component 3 is provided on the top of the mounting plate 1. The anti-jamming component 3 includes a sensor 31. The bottom of the sensor 31 is fixedly connected to the top of the mounting plate 1. A connecting rod 33 is rotatably connected to the top of the sensor 31. One end of the connecting rod 33 is fixedly connected to a foot pedal 34. A control box 35 is fixedly connected to the side of the sensor 31. A movable plate 36 is slidably connected to the inner wall of the control box 35. A fixed plate 37 is fixedly connected to the inner wall of the control box 35. A push rod 38 is fixedly connected to the top of the movable plate 36. The end of the push rod 38 away from the movable plate 36 passes through the top of the control box 35. An oil outlet pipe 39 passes through the side of the control box 35.

[0033] In some examples, there are two fixed plates 37, which are symmetrical to each other along the vertical central axis of the movable plate 36. The end of the push rod 38 away from the movable plate 36 is fixedly connected to a contact plate 5. The design of the contact plate 5 increases the contact area, which facilitates the pressing of the push rod 38.

[0034] A limit rod 312 is fixedly connected to the inner wall of the control box 35. The end of the limit rod 312 away from the control box 35 passes through the bottom of the moving plate 36. The design of the limit rod 312 helps to limit the movement trajectory of the moving plate 36 and prevent the movement trajectory of the moving plate 36 from deviating.

[0035] A spring 311 is fixedly connected to the inner wall of the control box 35. The end of the spring 311 away from the control box 35 is fixedly connected to the bottom of the moving plate 36. The design of the spring 311 is conducive to the automatic reset when the moving plate 36 is not squeezed.

[0036] The end of the oil outlet pipe 39 away from the control box 35 is located on the side of the connecting rod 33. A plug 310 is provided on the side of the oil outlet pipe 39, and a connecting pipe port 32 is opened on the side of the sensor 31. The plug 310 is designed to block the oil outlet of the oil outlet pipe 39 when lubricant is not needed, thus preventing continuous oil leakage.

[0037] A short pipe 313 runs through the side of the control box 35. A storage tank 314 runs through the end of the short pipe 313 away from the control box 35. A replenishment pipe 315 runs through the top of the storage tank 314. The design of the replenishment pipe 315 facilitates the replenishment of oil to the storage tank 314.

[0038] For example, such as Figures 1-5 As shown in this application, the storage box 314 stores lubricant, which is transferred into the control box 35 through the short pipe 313. The control box 35 contains two fixed plates 37 and one movable plate 36. The short pipe 313 is located above the two fixed plates 37 and one movable plate 36 inside the control box 35. Therefore, the lubricant transferred in will initially be located at the top of the fixed plates 37 and the movable plate 36 inside the control box 35. However, the oil outlet pipe 39 is located below the fixed plates 37 and the movable plate 36, so the lubricant cannot flow out temporarily. When the foot pedal 34 and connecting rod 33 are pressed, a jamming occurs. The contact plate 5 can be pressed down, causing the push rod 38 to move downwards. The downward movement of the push rod 38 will cause the movable plate 36 to move downwards. The movable plate 36, limited by the limit rod 312, moves vertically downwards. The downward movement of the movable plate 36 will cause the two... A notch is opened in the middle of the fixed plate 37, allowing the lubricant above to flow down to the control box 35. The lubricant flowing down can then exit through the oil outlet pipe 39, which is located at the rotor shaft where the connecting rod 33 connects to the sensor 31. The exiting lubricant can lubricate the rotating parts of the connecting rod 33, preventing the pedal 34 from becoming stuck when pressed. By lubricating the rotating parts of the connecting rod 33, friction can be reduced, avoiding any sticking or jamming when pressing the pedal. This is very important for electronic accelerator pedals, because if there is too much friction or sticking, the driver may experience an unsmooth experience during acceleration, affecting driving comfort and safety. Regular lubrication can reduce wear between components, lower the failure rate, and increase the overall reliability of the system.

[0039] like Figures 1-5As shown, this invention illustrates an electronic accelerator pedal for automobiles in another embodiment, comprising: a heat dissipation assembly 4 disposed on the top of a mounting plate 1, the heat dissipation assembly 4 including a pressing rod 41, one end of the pressing rod 41 being fixedly connected to the outer wall of a push rod 38, a vertical rod 42 being fixedly connected to the side of the mounting plate 1, a rotating shaft 45 being rotatably connected to the side of the vertical rod 42, fan blades 46 being fixedly connected to the circumferential surface of the rotating shaft 45, and an inclined rod 47 being fixedly connected to the circumferential surface of the rotating shaft 45. By driving the fan blades 46 to rotate, wind power is generated to blow air and cool the sensor 31.

[0040] In some examples, the fan blade 46 is located on the side of the sensor 31, and a short rod 43 is fixedly connected to the side of the vertical rod 42. One end of the short rod 43 is fixedly connected to the housing 44. The design of the housing 44 is conducive to protecting the fan blade 46 and preventing the fan blade 46 from being interfered with.

[0041] The fan blades 46 and the rotating shaft 45 are located on the inner wall of the outer casing 44. The tilting rod 47 is located on the displacement trajectory of the extrusion rod 41. Several fan blades 46 are arranged and are arranged in a circumferential array on the circumferential surface of the rotating shaft 45. This design is beneficial to extruding the tilting rod 47 when the extrusion rod 41 moves.

[0042] A torsion spring 48 is fixedly connected to the circumferential surface of the rotating shaft 45. The end of the torsion spring 48 away from the rotating shaft 45 is fixedly connected to the side of the housing 44. A protective grille 49 is fixedly connected to the side of the housing 44. The design of the torsion spring 48 is conducive to self-resetting when the rotating shaft 45 is not compressed.

[0043] For example, such as Figures 1-5 As shown, the downward movement of the push rod 38 causes the compression rod 41 to move downward. The tilting rod 47 is located on the movement trajectory of the compression rod 41. The downward movement of the compression rod 41 compresses the tilting rod 47, causing it to rotate downward. The rotation of the tilting rod 47 causes the rotating shaft 45 to rotate on the side of the vertical rod 42. The rotation of the rotating shaft 45 causes the fan blades 46 to rotate. The rotation of the fan blades 46 generates wind. The sensor 31 is located on the side of the fan blades 46. The wind generated by the rotation of the fan blades 46 blows directly onto the side of the sensor 31, providing direct cooling for the sensor 31. The rotation of the fan blades 46 generates wind that blows directly onto the sensor 31, aiding in heat dissipation. Electronic accelerator pedals typically involve electronic sensors 31 and related circuits. These electronic components generate heat during use. This heat dissipation mechanism effectively reduces the temperature, preventing electronic components from malfunctioning due to overheating, thereby extending the service life of the electronic sensor 31 and the pedal system, and improving system stability and reliability.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
