Description

Technical Field

[0001] This invention relates to the field of electronic throttle pedal technology, specifically to an electronic throttle pedal for new energy vehicles. Background Technology

[0002] In the field of new energy vehicles, the electronic throttle pedal, as a core control component for power output, directly affects driving safety in terms of its reliability.

[0003] In existing technologies, electronic accelerator pedals typically employ electric or electronic sensing structures, transmitting throttle signals through contact sliding or the Hall effect. However, when one end of the pedal becomes stuck due to an accident (such as being jammed by a floor mat, foreign object intrusion, or mechanical component failure), the vehicle will remain in a state of continuous acceleration. This can easily lead to serious safety accidents such as rear-end collisions and loss of control, especially at high speeds or in complex road conditions. Therefore, there is an urgent need for an electronic accelerator pedal for new energy vehicles to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an electronic accelerator pedal for new energy vehicles. It employs a purely mechanical overload trip design. When high-frequency pedaling causes the shaft angular velocity to exceed a threshold, the centrifugal force of the counterweight triggers the gear transmission chain, causing the lifting ring plate to lift the crossbar, thus separating the contact from the resistive diaphragm and cutting off the accelerator signal. This structure requires no electricity and can still work reliably under extreme conditions such as vehicle electronic system failure, avoiding the risk of "runaway" and solving the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electronic accelerator pedal for a new energy vehicle, comprising a pedal arm, one end of which is fixedly connected to a pedal, and the other end of which is fixedly connected to a rotating shaft.

[0013] Preferably, the density of mounting holes formed beneath the resistive film coating gradually decreases in the direction away from the contact.

[0014] Preferably: a first rotating rod is fixedly connected to the top outer wall of the rotating shaft, a sleeve is fixedly connected to the circumferential outer wall of the first rotating rod, a first spring is fixedly connected to one inner wall of the sleeve, a counterweight is fixedly connected to the other end of the first spring, the counterweight is slidably connected to the sleeve, an arc-shaped plate is provided inside the housing, and one end of the counterweight contacts the circumferential inner wall of the arc-shaped plate.

[0015] Preferably, a rack is fixedly connected to the outer circumference of the arc-shaped plate, a gear disk meshes with the bottom of the rack, and a first rotating rod is fixedly connected to the inner circumference of the gear disk.

[0016] Preferably, the protection component includes a fifth helical gear fixedly connected to one end of the first rotating rod, a fourth helical gear meshing with the outer circumferential wall of the fifth helical gear, a third rotating rod fixedly connected to the inner circumferential wall of the fourth helical gear, a third helical gear fixedly connected to the outer circumferential wall of the third rotating rod, a first helical gear meshing with the inner circumferential wall of the third helical gear, a second rotating rod fixedly connected to the inner circumferential wall of the first helical gear, a vertical plate fixedly connected to one side of the side plate, the second rotating rod rotatably connected to the vertical plate, a second helical gear fixedly connected to the other end of the second rotating rod, a sixth helical gear meshing with the outer circumferential wall of the second helical gear, a threaded screw fixedly connected to the inner circumferential wall of the sixth helical gear, a threaded sleeve threadedly connected to the outer circumferential wall of the threaded screw, an L-shaped plate fixedly connected to one outer wall of the threaded sleeve, and a lifting ring plate fixedly connected to the other end of the L-shaped plate. The lifting ring plate is located below the crossbar, and the contact can be separated from the resistive film coating by the lifting ring plate rising.

[0017] Preferably, a guide rod is fixedly connected to one outer wall of the side plate, and a guide cylinder is sleeved on the outer circumference of the guide rod. The guide cylinder is fixedly connected to the lifting ring plate through the L-shaped plate.

[0020] Compared with the prior art, the present invention provides an electronic accelerator pedal for new energy vehicles, which has the following beneficial effects:

[0021] The protective enclosure of the resistive film coating within the variable resistance assembly effectively prevents dust and moisture intrusion. Combined with the second spring and guide post, this ensures vertical movement of the crossbar, preventing contact misalignment and significantly improving signal stability and assembly lifespan. The protection assembly employs a purely mechanical overload trip design. When high-frequency pedaling causes the shaft angular velocity to exceed the threshold, the centrifugal force of the counterweight triggers the gear transmission chain, causing the lifting ring plate to lift the crossbar, separating the contact from the resistive film and cutting off the throttle signal. This structure requires no electricity and can still reliably operate under extreme conditions such as vehicle electronic system failure. To avoid the risk of "runaway" movement, the limiting component uses a limiting groove and a baffle locking mechanism to ensure that the lifting ring plate does not fall back unexpectedly after the protection component is triggered, thus maintaining the contact separation state and improving the reliability of safety protection. The automatic filling component uses microcapsules in the mounting holes to store conductive paste. When the contact slides, the tooth groove punctures the microcapsules to release the paste and fill the wear pits of the resistive film. The silicone scraper removes impurities and levels the paste. The density of the mounting holes decreases along the direction away from the contact, so that the first half of the high-frequency wear zone is repaired first, realizing dynamic wear repair and precision maintenance.

[0034] 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.

[0035] Please see Figures 1-11 An electronic accelerator pedal for a new energy vehicle includes a pedal arm 1, with a pedal 2 fixedly connected to one end of the pedal arm 1 and a rotating shaft 6 fixedly connected to the other end of the pedal arm 1. Side plates 4 are rotatably connected to both ends of the rotating shaft 6. A mounting base 3 and a housing 5 are fixedly connected to one outer wall of each side plate 4. The pedal also includes:

[0036] A variable resistance assembly 8 for controlling the throttle of a new energy vehicle includes a horizontal plate 804 fixedly connected to the outer wall of one side of the side plate 4. Two sets of variable resistance components are provided on the outer wall of one side of the horizontal plate 804. Each set of variable resistance components includes two resistive film coatings 802. A enclosure plate 801 for protecting the resistive film coatings 802 is fixedly connected to the outer wall of one side of the fixed plate 803. A crossbar 807 is provided on the outer circumference of the rotating shaft 6. A contact 808 that can form an electrical connection with the resistive film coatings 802 is provided at the bottom of the crossbar 807.

[0037] Protection component 7 for overload tripping of the electronic throttle pedal;

[0038] Limiting component 9 is used to ensure the stable operation of protection component 7;

[0039] The elastic plate 10 enables the pedal 2 and pedal arm 1 to quickly return to their original position after being stepped on;

[0040] The automatic filling assembly used to repair the resistive film coating 802, in the variable resistor assembly 8, the enclosure plate 801 acts as a protective barrier for the resistive film coating 802, effectively blocking the intrusion of impurities such as dust and moisture, preventing the resistive film coating 802 from being damaged by external factors and affecting signal transmission. At the same time, the bottom of the horizontal plate 804 on the outer circumference of the rotating shaft 6 is connected to the second spring 806 and the crossbar 807. The guide post 805 at the top of the crossbar 807 passes through the horizontal plate 804. The second spring 806 and the guide post 805 work together to ensure that the crossbar 807 always remains vertical during movement, avoiding the contact 808 from tilting, thereby significantly improving signal stability and the service life of the variable resistor assembly 8, enabling the contact 808 and the resistive film coating 802 to form a stable electrical connection and accurately control the throttle signal.

[0041] To effectively avoid signal transmission instability caused by the swaying or tilting of the crossbar 807, please refer to... Figure 1 , Figure 6 A horizontal plate 804 is fixedly connected to the outer circumference of the rotating shaft 6. A second spring 806 is fixedly connected to the bottom outer wall of the horizontal plate 804. The second spring 806 is fixedly connected to the crossbar 807. A guide post 805 is fixedly connected to the top outer wall of the crossbar 807. One end of the guide post 805 passes through the top of the horizontal plate 804. The horizontal plate 804 fixed to the outer circumference of the rotating shaft 6, the second spring 806 at the bottom, and the guide post 805 at the top of the crossbar 807 together constitute a stable transmission structure. The second spring 806 provides elastic support for the crossbar 807. When the pedal arm 1 drives the rotating shaft 6 to rotate, the crossbar 807 can move flexibly under the action of the second spring 806. The guide post 805 restricts the direction of movement of the crossbar 807, ensuring that it can only move vertically up and down, making the contact between the contact 808 and the resistive film coating 802 more stable and reliable.

[0042] For details on the structure of the autofill component, please refer to [link / reference]. Figure 1 , Figure 7 , Figure 8The automatic filling component includes mounting holes 12 on the top outer wall of the horizontal plate 804. Microcapsules 11 are disposed inside the mounting holes 12, and each microcapsule contains a conductive paste for repairing the worn resistive film coating 802. Connecting plates 810 are fixedly connected to both outer walls of the contact 808. Scrapers 811, made of silicone material, are fixedly connected to both ends of the connecting plates 810 for leveling the conductive paste and scraping impurities from the top of the resistive film coating 802. The outer walls of both sides of the contact 808 have evenly spaced... The toothed grooves 809 rapidly puncture the microcapsules 11. When the contact 808 slides on the resistive film coating 802, the toothed grooves 809 on both sides will puncture the microcapsules 11, and the released conductive paste can fill the wear pits of the resistive film coating 802. The scrapers 811 on the connecting plates 810 on both sides of the contact 808 are made of silicone material. During the sliding process of the contact 808, the scrapers 811 can level the released conductive paste and scrape off the impurities on the top of the resistive film coating 802, ensuring that the surface of the repaired resistive film coating 802 is flat and has good conductivity.

[0043] To ensure the accuracy and conductivity of the 802 resistive film coating in high-frequency wear regions, please refer to... Figure 1 The density of mounting holes 12 below a resistive film coating 802 gradually decreases in the direction away from the contact 808. During use, the first half of the contact 808 in contact with the resistive film coating 802 is a high-frequency wear area, which is more prone to wear and pitting. By increasing the density of mounting holes 12 in this area, more microcapsules 11 can be stored to store conductive paste. When wear occurs in this area, more paste can be released in time for repair, improving the repair effect and efficiency.

[0044] This provides the power source for triggering the subsequent protection component 7, enabling overload protection of the electronic throttle pedal. Please refer to [link / reference needed]. Figure 1 , Figure 3 , Figure 4 , Figure 5 A first rotating rod 704 is fixedly connected to the top outer wall of the rotating shaft 6. A sleeve 701 is fixedly connected to the circumferential outer wall of the first rotating rod 704. A first spring 709 is fixedly connected to the inner wall of one side of the sleeve 701. A counterweight 702 is fixedly connected to the other end of the first spring 709. The counterweight 702 is slidably connected to the sleeve 701. An arc plate 711 is provided inside the housing 5. One end of the counterweight 702 is in contact with the circumferential inner wall of the arc plate 711. When the pedal 2 is stepped on at an abnormally high frequency, causing the angular velocity of the rotating shaft 6 to exceed the threshold, the counterweight 702 inside the sleeve 701 will be thrown outward due to centrifugal force overcoming the resistance of the first spring 709, thereby pushing the arc plate 711 to move horizontally.

[0045] To ensure efficient power transmission and successful triggering of protection component 7, please refer to... Figure 1 , Figure 3 , Figure 4 , Figure 5 A rack 703 is fixedly connected to the outer circumference of the arc plate 711. A gear disk 705 meshes with the bottom of the rack 703. A first rotating rod 704 is fixedly connected to the inner circumference of the gear disk 705. When the arc plate 711 moves horizontally under the push of the counterweight 702, the rack 703 drives the gear disk 705 to rotate. The gear disk 705 then drives the first rotating rod 704 fixedly connected to it to rotate, thereby converting the horizontal movement of the arc plate 711 into the rotational movement of the first rotating rod 704, providing initial power for the subsequent gear transmission chain in the protection component 7.

[0046] For details regarding the specific structure of the protection component 7, please refer to [link / reference]. Figure 3 , Figure 11 The protective assembly 7 includes a fifth helical gear 724 fixedly connected to one end of the first rotating rod 704. A fourth helical gear 723 meshes with the outer circumference of the fifth helical gear 724. A third rotating rod 717 is fixedly connected to the inner circumference of the fourth helical gear 723. A third helical gear 716 is fixedly connected to the outer circumference of the third rotating rod 717. A first helical gear 712 meshes with the inner circumference of the third helical gear 716. A second rotating rod 714 is fixedly connected to the inner circumference of the first helical gear 712. A vertical plate 713 is fixedly connected to one side of the side plate 4. The second rotating rod 714 is rotatably connected to the vertical plate 713. A second helical gear 715 is fixedly connected to the other end of the second rotating rod 714. The second helical gear 715 has a circumference of... The outer wall is meshed with a sixth helical gear 725. A threaded screw 706 is fixedly connected to the inner circumference of the sixth helical gear 725. A threaded sleeve 707 is threadedly connected to the outer circumference of the threaded screw 706. An L-shaped plate 722 is fixedly connected to one side of the outer wall of the threaded sleeve 707. A lifting ring plate 708 is fixedly connected to the other end of the L-shaped plate 722. The lifting ring plate 708 is located below the crossbar 807. The lifting ring plate 708 can separate the contact 808 from the resistive film coating 802 by rising. The entire protection component 7 adopts a purely mechanical overload trip design, which does not require electricity. It can still work reliably under extreme conditions such as failure of the vehicle's electronic system, avoiding the risk of "runaway" due to the accelerator pedal being stuck, and ensuring driving safety.

[0047] To ensure the triggering effect and stability of protection component 7, please refer to... Figure 1 , Figure 3A guide rod 720 is fixedly connected to one outer wall of the side plate 4. A guide cylinder 719 is sleeved on the outer circumference of the guide rod 720. The guide cylinder 719 is fixedly connected to the lifting ring plate 708 through the L-shaped plate 722. During the triggering process of the protection component 7, when the threaded sleeve 707 drives the L-shaped plate 722 and the lifting ring plate 708 to move upward, the guide rod 720 and the guide cylinder 719 play a guiding and stabilizing role, ensuring that the lifting ring plate 708 can rise smoothly in the vertical direction, accurately lift the crossbar 807, and reliably separate the contact 808 from the resistive film coating 802, avoiding the lifting ring plate 708 from shaking or deviating during the movement.

[0048] To improve the reliability of safety protection and ensure the vehicle remains in a safe state even when the accelerator pedal malfunctions, please refer to... Figure 1 , Figure 4 , Figure 5 The limiting component 9 includes a limiting plate 901 fixedly connected to the inner circumference of the housing 5. A limiting groove 902 is formed on the top of the limiting plate 901. A sliding column is fixedly connected to the top outer wall of the arc plate 711. The sliding column is slidably connected to the limiting groove 902. A sliding plate 903 is fixedly connected to the top of the sliding column. When the protection component 7 is triggered, the arc plate 711 moves, and the sliding column at its top slides in the limiting groove 902. The sliding plate 903 pushes the baffles 904, which are distributed in a figure-eight shape, to open. The third spring 905 is stretched and then locks the sliding column to prevent the lifting ring plate 708 from falling back unexpectedly, ensuring that the contact 808 and the resistive film coating 802 are continuously separated. After the protection component 7 is triggered, the locking mechanism of the limiting component 9 is used.

[0049] To achieve stable limiting after the protection component 7 is triggered and enhance the safety performance of the electronic throttle pedal, please refer to... Figure 1 , Figure 4 , Figure 5 A connecting rod 906 is fixedly connected to the top outer wall of the limiting plate 901, and a baffle 904 is rotatably connected to the top outer wall of the limiting plate 901. A third spring 905 is fixedly connected to one side outer wall of the baffle 904, and the other end of the third spring 905 is fixedly connected to the connecting rod 906. The two baffles 904 are arranged in a V-shape on the top of the limiting plate 901. When the protection component 7 is triggered, the sliding column at the top of the arc plate 711 moves upward, and the sliding plate 903 pushes the baffle 904 to open against the tension of the third spring 905. When the sliding column moves to a certain position, the third spring 905 resets and pulls the baffle 904 back to lock the sliding column, thereby restricting the movement of the arc plate 711 and ensuring that the lifting ring plate 708 will not fall back unexpectedly, and ensuring that the contact 808 and the resistive film coating 802 always remain separated.

[0050] When in use, when the driver presses pedal 2, the pedal arm 1 drives the rotating shaft 6 to rotate, causing the contact 808 at the bottom of the crossbar 807 to slide on the resistive film coating 802. By changing the resistance value, an throttle electrical signal is generated. This signal is transmitted to the vehicle ECU via wires to control the motor power. During this process, the crossbar 807 is connected to the cross plate 804 through the second spring 806. The guide post 805 ensures its vertical movement and prevents the contact 808 from tilting. The enclosure plate 801 forms a protective barrier for the resistive film coating 802, effectively preventing dust and moisture from entering and improving signal stability and component lifespan.

[0051] When an accident occurs during driving that causes pedal 2 to fail to return, the driver will instinctively and repeatedly depress pedal 2. At this time, the counterweight 702 inside the sleeve 701 will be thrown outward due to centrifugal force, overcoming the resistance of the first spring 709, thereby pushing the arc plate 711 to move horizontally. When the arc plate 711 moves horizontally, the rack 703 on its outer wall will drive the gear disk 705 to rotate, which in turn drives the first rotating rod 704 to rotate. Through the meshing of the fifth helical gear 724 and the fourth helical gear 723, the rotation is transmitted to the third rotating rod 717, the third helical gear 716, and the first helical gear 712. The second rotating rod 714, with its second helical gear 715 driving the sixth helical gear 725, causes the threaded screw 706 to rotate. The threaded sleeve 707 moves upward along the guide rod 720, pushing the lifting ring plate 708 through the L-shaped plate 722 to lift the crossbar 807, causing the contact 808 to separate from the resistive film coating 802, cutting off the throttle signal, and causing the vehicle to lose its power source. This prevents the vehicle from failing to decelerate and causing an accident. Furthermore, the entire protection component 7 is a purely mechanical overload protection structure that does not require electricity. It can still work reliably under extreme conditions such as vehicle electronic system failure, avoiding the risk of "runaway".

[0052] When the protective component is triggered, the sliding column at the top of the arc plate 711 slides in the limiting groove 902, the slide plate 903 pushes the baffle 904, which is distributed in a figure-eight shape, to open, and the third spring 905 is stretched and jammed to prevent the lifting ring plate 708 from falling back unexpectedly, ensuring that the contact 808 continues to separate and improving the reliability of safety protection.

[0053] Meanwhile, during the long-term operation of the variable resistor assembly 8, the resistive film coating 802 will wear down and even develop pits due to the long-term scraping by the contact 808. This will significantly reduce the control accuracy of the entire variable resistor assembly 8. When pits appear in the resistive film coating 802, the microcapsules 11 located in the mounting hole 12 will quickly pop out. Subsequently, when the contact 808 slides on top of the resistive film coating 802, the toothed grooves 809 on both sides pierce the microcapsules 11 in the mounting hole 12, thereby rapidly releasing the conductive paste inside the microcapsules 11. The wear pits of the charging resistive film coating 802 and the density of the mounting holes 12 gradually decrease along the direction away from the contact 808, so that the first half of the high-frequency wear zone is preferentially replenished with slurry. In conjunction with the silicone scraper 811 driven by the connecting plate 810, impurities are scraped off and the slurry is leveled. After curing, a new conductive layer is formed, realizing dynamic wear repair and precision maintenance. In addition, the elastic piece 10 is installed between the pedal arm 1 and the fixed seat 3. When stepped on, it stores potential energy. When released, it pushes the pedal arm 1 to reset and drives the contact 808 back to the initial position, ensuring the continuity and convenience of pedal 2 operation.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
