Description

Technical Field

[0001] This invention relates to the field of accelerator pedal technology, specifically to an automotive accelerator pedal with speed feedback function. Background Technology

[0002] The accelerator pedal is a key component controlling the vehicle's power output, located on the bottom right side of the driver's compartment. It adjusts the throttle opening in traditional gasoline vehicles or the motor power in electric vehicles by the force and travel of the driver's pedal, thus achieving acceleration, deceleration, and speed maintenance.

[0003] Currently, most car accelerator pedals have uniform pedal resistance, making it difficult for users to accurately perceive vehicle speed while driving, which can easily lead to speeding and affect driving safety. To address this, we propose a car accelerator pedal with speed feedback function. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a car accelerator pedal with speed feedback function, which solves the problem that most existing car accelerator pedals have uniform pedal resistance, making it difficult for users to accurately perceive vehicle speed during driving, easily leading to speeding and affecting driving safety.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a car accelerator pedal with speed feedback function, comprising a mounting bracket, a positioning block mounted on the surface of the mounting bracket, an assembly hole formed on the surface of the mounting bracket, a carrier mounted on the inner wall of the positioning block, a stabilizing block fixedly connected to the side of the mounting bracket near the positioning block, a pedal arm rotatably connected to the inner wall of the stabilizing block, a pedal body fixedly connected to one end of the pedal arm, an anti-slip block fixedly connected to the surface of the pedal body, a transmission rod rotatably connected to the surface of the pedal body, a control bracket rotatably connected to one end of the transmission rod, an accelerator pedal position sensor mounted on the surface of the mounting bracket, the output end of the accelerator pedal position sensor penetrating the mounting bracket, and a transmission sleeve mounted on the output end of the accelerator pedal position sensor. Fixedly connected to the inner wall of the control frame, the transmission sleeve is equipped with a feedback device on its surface. When the driver presses down on the pedal body, the pedal body rotates around the connection point between the pedal arm and the stabilizing block. The anti-slip block ensures stable contact between the foot and the pedal. The rotation of the pedal body drives the control frame to move through the transmission rod. The displacement or angle change of the control frame is directly transmitted to the transmission sleeve fixedly connected to it, thereby causing the output end of the accelerator pedal position sensor to move synchronously. The accelerator pedal position sensor converts this physical displacement into a proportional electrical signal and transmits it to the engine control unit. Through the linkage of the compression spring and the counterweight, the pedal resistance increases proportionally with the depth of the pedal. The driver can sense the change in resistance with his foot and accurately judge the accelerator opening, avoiding sudden power changes caused by accidental pressing, especially improving handling safety in congested urban areas or when cruising at high speeds.

[0008] Preferably, the feedback device includes a guide plate, which is fixedly connected to the surface of the transmission sleeve. A support rod is fixedly connected to the surface of the carrier frame. A rotating rod is rotatably connected to the inner wall of the support rod. A guide wheel is fixedly connected to the rotating rod. A pull rope is fixedly connected to the end of the guide plate away from the transmission sleeve. A mounting cover is placed inside the carrier frame. Clamps are fixedly connected to both sides of the mounting cover. Bolts are threaded onto the inner wall of the clamps. One end of the bolt is threaded into the carrier frame. A sliding rod is slidably connected to the inner wall of the mounting cover. The pull rope is located away from the transmission sleeve. One end of the transmission sleeve passes through the guide wheel and is fixedly connected to the upper end of the slide rod. The lower end of the slide rod is fixedly connected to a sliding plate. The sliding plate is slidably connected to the inner wall of the mounting cover. A compression spring is fixedly connected to the upper surface of the sliding plate. The upper end of the compression spring is fixedly connected to the inner top wall of the mounting cover. The counterweight and the spring combine to form a linkage feedback. When the vehicle is traveling at high speed, the counterweight works with the compression spring to increase the pedal resistance as the vehicle speed increases, preventing excessive acceleration caused by pressing the accelerator pedal too hard at high speed. At low speed, the resistance automatically decreases, improving following comfort.

[0009] Preferably, the upper surface of the mounting cover is provided with vent holes. The vent holes on the mounting cover can balance the internal air pressure and prevent air resistance when the slide rod slides.

[0010] Preferably, a threaded sleeve is fixedly connected to the lower surface of the mounting cover, a threaded rod is threadedly connected to the threaded sleeve, a counterweight is fixedly connected to the lower end of the threaded rod, and a protrusion is fixedly connected to the lower surface of the counterweight. This solution supports quick manual replacement of the counterweight, adapts to the needs of different driving habits, and ensures driving safety.

[0011] Preferably, the lower surface of the protrusion is provided with a groove, and a pull rod is fixedly connected to the inner wall of the groove.

[0012] Preferably, a protective plate is fixedly connected to the upper surface of the support rod. The protective plate is located above the guide wheel. When the transmission sleeve rotates, the guide plate on its surface moves accordingly. The guide wheel pulls the slide rod downward through the pull rope, and the slide plate at the lower end of the slide rod compresses the spring. The spring deformation generates upward resistance, which is fed back to the pedal through the pull rope. This causes the driver's pedal pressure to increase with the pedal depth. The protective plate and the limiting block prevent the pull rope from detaching from the guide wheel, ensuring the stability of the feedback force transmission. Ultimately, the driver can clearly perceive the matching state between the current throttle depth and the vehicle speed through the change in pedal resistance, thus realizing the speed feedback function.

[0013] Preferably, the lower surface of the protective plate is fixedly connected to two symmetrically arranged limiting blocks, which are located on both sides of the pull rope to effectively limit the position of the pull rope and prevent the pull rope from detaching from the guide wheel.

[0014] Preferably, the inner wall of the mounting cover is provided with a stabilizing device, the stabilizing device includes a protruding rod, the lower end surface of the protruding rod is threaded, a positioning frame is sleeved on the protruding rod, a retaining sleeve is fixedly connected to the surface of the positioning frame, the retaining sleeve is sleeved on the protruding rod, and a nut is threadedly connected to the protruding rod.

[0015] Preferably, a pressure ring is fixedly connected to the surface of the nut, a sliding sleeve is slidably connected to the nut, a positioning spring is fixedly connected to the upper end of the sliding sleeve, the upper end of the positioning spring is fixedly connected to the lower surface of the pressure ring, support rods are fixedly connected to both sides of the sliding sleeve, and a stop block is fixedly connected to the end of the support rod away from the sliding sleeve. The stop block is adapted to the edge of the positioning frame. When it is necessary to adjust the resistance, pull down the support rod to drive the stop block away from the positioning frame, then turn the handle to drive the nut away from the protruding rod, then remove the nut, and then... Remove the mounting bracket and ferrule. Then, insert your fingers into the groove and pinch the pull rod to rotate the protrusion, which will in turn rotate the counterweight and threaded rod. Once the threaded rod disengages from the threaded sleeve, remove it. Then, select a counterweight of appropriate weight for replacement. After replacement, put the ferrule on the protrusion, then put the mounting bracket on the protrusion. Next, rotate the nut to fit it onto the protrusion. After the pressure ring abuts against the mounting bracket, release the bracket, the positioning spring will return to its original position, and the stop block will engage with the mounting bracket, completing the counterweight replacement operation and increasing the adaptability of the equipment.

[0016] Preferably, a handle is fixedly connected to the lower end of the nut, and pulling the handle can effectively drive the nut to rotate.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. In this invention, through the linkage between the compression spring and the counterweight, the pedal resistance increases proportionally with the depth of pedal application. The driver can sense the change in resistance with their foot and accurately judge the throttle opening, avoiding sudden power changes caused by accidental pedal application, which improves handling safety, especially in congested urban areas or when cruising at high speeds.

[0019] 2. In this invention, the counterweight and spring are combined to form a linkage feedback. When the vehicle is traveling at high speed, the counterweight works with the compression spring to increase the pedal resistance as the vehicle speed increases, preventing excessive acceleration caused by pressing the accelerator pedal too hard at high speed. At low speed, the resistance automatically decreases, improving following comfort.

[0020] 3. This invention supports quick manual replacement of counterweights to meet the needs of different driving habits and ensure driving safety. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] refer to Figures 1-9The illustrated car accelerator pedal with speed feedback function includes a mounting bracket 1. A positioning block 2 is mounted on the surface of the mounting bracket 1. The surface of the mounting bracket 1 has mounting holes 11. A carrier 3 is mounted on the inner wall of the positioning block 2. A stabilizing block 6 is fixedly connected to the side of the mounting bracket 1 near the positioning block 2. A pedal arm 7 is rotatably connected to the inner wall of the stabilizing block 6. One end of the pedal arm 7 is fixedly connected to a pedal body 8. An anti-slip block 9 is fixedly connected to the surface of the pedal body 8. A transmission rod 10 is rotatably connected to the surface of the pedal body 8. One end of the transmission rod 10 is rotatably connected to a control frame 12. An accelerator pedal position sensor 14 is mounted on the surface of the mounting bracket 1. The output end of the accelerator pedal position sensor 14 passes through the mounting bracket 1. A transmission sleeve 13 is mounted on the output end of the accelerator pedal position sensor 14. The transmission sleeve 13 is fixedly connected to the inner wall of the control frame 12. The surface of pedal 3 is equipped with a feedback device 4. When the driver presses the pedal body 8, the pedal body 8 rotates around the connection point between the pedal arm 7 and the stabilizing block 6. The anti-slip block 9 ensures stable contact between the foot and the pedal. The rotation of the pedal body 8 drives the control frame 12 to move through the transmission rod 10. The displacement or angle change of the control frame 12 is directly transmitted to the transmission sleeve 13 fixedly connected to it, thereby causing the output end of the accelerator pedal position sensor 14 to move synchronously. The accelerator pedal position sensor 14 converts this physical displacement into a proportional electrical signal and transmits it to the engine control unit. Through the linkage of the compression spring 46 and the counterweight 49, the pedal resistance increases proportionally with the depth of the pedal. The driver can sense the change in resistance with his foot and accurately judge the accelerator opening, avoiding sudden power changes caused by accidental pressing, especially improving handling safety in congested urban areas or when cruising at high speed.

[0033] The feedback device 4 includes a guide plate 41, which is fixedly connected to the surface of the transmission sleeve 13. A support rod 416 is fixedly connected to the surface of the carrier frame 3. A rotating rod 417 is rotatably connected to the inner wall of the support rod 416. A guide wheel 43 is fixedly connected to the rotating rod 417. A pull rope 42 is fixedly connected to the end of the guide plate 41 away from the transmission sleeve 13. A mounting cover 45 is placed inside the carrier frame 3. A bracket 411 is fixedly connected to both sides of the mounting cover 45. A bolt 412 is threadedly connected to the inner wall of the bracket 411. One end of the bolt 412 is threaded into the carrier frame 3. A sliding rod 44 is slidably connected to the inner wall of the mounting cover 45. The pull rope... The end of 42 away from the transmission sleeve 13 passes through the guide wheel 43 and is fixedly connected to the upper end of the slide rod 44. The lower end of the slide rod 44 is fixedly connected to the slide plate 47. The slide plate 47 is slidably connected to the inner wall of the mounting cover 45. The upper surface of the slide plate 47 is fixedly connected to the compression spring 46. The upper end of the compression spring 46 is fixedly connected to the inner top wall of the mounting cover 45. The counterweight 49 and the spring form a linkage feedback. When the vehicle is traveling at high speed, the counterweight 49 works with the compression spring 46 to increase the pedal resistance as the vehicle speed increases, preventing excessive acceleration caused by pressing the accelerator pedal deeply at high speed. At low speed, the resistance automatically decreases, improving following comfort.

[0034] The upper surface of the mounting cover 45 is provided with a vent hole 420. The vent hole 420 on the mounting cover 45 can balance the internal air pressure and prevent air resistance when the slide rod 44 slides.

[0035] The lower surface of the mounting cover 45 is fixedly connected to a threaded sleeve 410, and a threaded rod 48 is threadedly connected to the threaded sleeve 410. The lower end of the threaded rod 48 is fixedly connected to a counterweight 49, and the lower surface of the counterweight 49 is fixedly connected to a protrusion 413. This solution supports quick manual replacement of the counterweight 49, adapts to the needs of different driving habits, and ensures driving safety.

[0036] The protrusion 413 has a groove 414 on its lower surface, and a pull rod 415 is fixedly connected to the inner wall of the groove 414.

[0037] A protective plate 418 is fixedly connected to the upper surface of the support rod 416. The protective plate 418 is located above the guide wheel 43. When the transmission sleeve 13 rotates, the guide plate 41 on its surface moves accordingly. The guide wheel 43 pulls the slide rod 44 through the pull rope 42 to slide downwards inside the mounting cover 45. The slide plate 47 at the lower end of the slide rod 44 compresses the spring 46. The spring deformation generates upward resistance. This resistance is fed back to the pedal through the pull rope 42, so that the driver's pedal pressure increases with the pedal depth. The protective plate 418 and the limit block 419 can prevent the pull rope 42 from detaching from the guide wheel 43, ensuring the stability of the feedback force transmission. Ultimately, the driver can clearly perceive the matching state between the current throttle depth and the vehicle speed through the change in pedal resistance, realizing the speed feedback function.

[0038] Among them, the lower surface of the protective plate 418 is fixedly connected to two symmetrically arranged limiting blocks 419. The two limiting blocks 419 are located on both sides of the pull rope 42, which effectively restricts the position of the pull rope 42 and prevents the pull rope 42 from detaching from the guide wheel 43.

[0039] The inner wall of the mounting cover 45 is provided with a stabilizing device 5, which includes a protruding rod 510. The lower end surface of the protruding rod 510 is threaded. A positioning frame 53 is sleeved on the protruding rod 510. A retaining sleeve 52 is fixedly connected to the surface of the positioning frame 53. The retaining sleeve 52 is sleeved on the protrusion 413. A nut 55 is threadedly connected to the protruding rod 510.

[0040] The nut 55 has a pressure ring 58 fixedly connected to its surface, and a sliding sleeve 56 slidably connected to the nut 55. A positioning spring 59 is fixedly connected to the upper end of the sliding sleeve 56, and the upper end of the positioning spring 59 is fixedly connected to the lower surface of the pressure ring 58. Support rods 57 are fixedly connected to both sides of the sliding sleeve 56, and a stop block 54 is fixedly connected to the end of the support rod 57 away from the sliding sleeve 56. The stop block 54 is adapted to the edge of the positioning frame 53. When it is necessary to adjust the resistance, pull down the support rod 57 to drive the stop block 54 to disengage from the positioning frame 53. Then, turn the handle 51 to drive the nut 55 to disengage from the protruding rod 510. Then, remove the nut 55, and then remove the positioning frame 53 and the retaining sleeve 52. Then, insert your fingers into the groove 414 and pinch the pull rod 415 to rotate the protrusion 413, thereby driving the counterweight 49 and the threaded rod 48 to rotate. When the threaded rod 48 disengages from the threaded sleeve 410, remove it. Then, select a counterweight 49 of appropriate weight for replacement. After the replacement is completed, put the sleeve 52 on the protrusion 413, and then put the positioning frame 53 on the protrusion 510. Then, rotate the nut 55 to put it on the protrusion 510. After the pressure ring 58 abuts against the positioning frame 53, release the bracket, the positioning spring 59 returns to its original position, and drives the stop block 54 to lock onto the positioning frame 53, completing the replacement operation of the counterweight 49 and increasing the adaptability of the equipment.

[0041] The lower end of the nut 55 is fixedly connected to a handle 51. Pulling the handle 51 will effectively drive the nut 55 to rotate.

[0042] The working principle of this invention is as follows: When the driver presses the pedal body 8, the pedal body 8 rotates around the connection point between the pedal arm 7 and the stabilizing block 6. The anti-slip block 9 ensures stable contact between the foot and the pedal. The rotation of the pedal body 8 drives the control frame 12 to move via the transmission rod 10. The displacement or angle change of the control frame 12 is directly transmitted to the transmission sleeve 13 fixedly connected to it, thereby causing the output end of the accelerator pedal position sensor 14 to move synchronously. The accelerator pedal position sensor 14 converts this physical displacement into a proportional electrical signal and transmits it to the engine control unit.

[0043] Simultaneously, as the transmission sleeve 13 rotates, the guide plate 41 on its surface moves accordingly. The pull rope 42, via the guide wheel 43, pulls the slide rod 44 downwards within the mounting cover 45. The slide plate 47 at the lower end of the slide rod 44 compresses the spring 46, causing the spring to deform and generate upward resistance. This resistance is fed back to the pedal via the pull rope 42, causing the driver's pedal pressure to increase with the depth of pedal application. The protective plate 418 and the limiting block 419 prevent the pull rope 42 from detaching from the guide wheel 43, ensuring the stability of the feedback force transmission. Ultimately, the driver can clearly perceive the matching state between the current throttle depth and the vehicle speed through changes in pedal resistance, achieving a speed feedback function.

[0044] During this process, the vent 420 on the mounting cover 45 can balance the internal air pressure and prevent air resistance when the slide rod 44 slides. When it is necessary to adjust the resistance, pull down the support rod 57 to drive the stop block 54 to disengage from the positioning frame 53. Then, turn the handle 51 to drive the nut 55 to disengage from the protrusion 510. Then, remove the nut 55, and then remove the positioning frame 53 and the retaining sleeve 52. Then, you can put your fingers into the groove 414 and pinch the pull rod 415 to rotate the protrusion 413, thereby driving the counterweight 49 and the threaded rod 4 8. Rotate until the threaded rod 48 disengages from the threaded sleeve 410, then remove it. Next, select a counterweight 49 of appropriate weight for replacement. After replacement, put the ferrule 52 on the protrusion 413, then put the positioning bracket 53 on the protrusion 510. Then, rotate the nut 55 to put it on the protrusion 510. After the pressure ring 58 abuts against the positioning bracket 53, release the bracket, the positioning spring 59 returns to its original position, and drives the stop block 54 to lock onto the positioning bracket 53, completing the replacement operation of the counterweight 49 and increasing the adaptability of the equipment.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
