Description

Technical Field

[0001] This utility model relates to the field of electronic throttle control technology, specifically to a bidirectional electronic throttle pedal. Background Technology

[0002] Electronic throttle control technology is a core component of modern automotive electronic systems, used to replace traditional mechanical throttles. It precisely adjusts the engine throttle opening via electronic signals, thereby achieving more efficient fuel management and driving response. With the development of automotive intelligence, electronic throttle pedals have become mainstream; however, in practical applications, existing technologies still have many shortcomings. These systems typically include a base, pedal arm, return spring, and sensor assembly, designed to provide linear throttle response. For example, many commercial vehicles use a single-axle pedal structure that relies on a spring mechanism to achieve pedal return.

[0003] The above-mentioned technical conditions also have shortcomings: most common electronic throttle pedals adopt a single-point control design, that is, only one master pedal is set, which makes it inconvenient to operate more complex engineering machinery.

[0004] Based on this, the present invention designs a bidirectional control electronic throttle pedal to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional control electronic throttle pedal to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional control electronic throttle pedal, comprising a base, a dust cover on the top of the base, a support seat on the dust cover, a front control pedal fixedly connected to the support seat, a rear control pedal connected to the bottom of the front control pedal, a spring seat connected to the bottom of the base, four sets of transmission rods on the base, the four sets of transmission rods being arranged in pairs at the bottom of the support seat, an outer spring being provided at the bottom end of the transmission rods, rotating seats fixedly connected to both sides of the top of the base, a central shaft being provided on the two sets of rotating seats, positioning sleeves being sleeved on both sides of the central shaft, a deflection seat being provided on the positioning sleeve, a mounting seat being provided on the deflection seat, the top of the mounting seat being fixedly provided at the bottom of the support seat, a magnet being provided on the deflection seat, and a Hall sensor circuit board adapted to the magnet being provided on the base.

[0007] By adopting the above technical solution, bidirectional control of the pedal (forward and backward pedals) can be achieved. Through the cooperation of magnets and Hall sensors, changes in pedal position can be accurately detected, and electronic signals can be output to control the throttle opening, thereby improving response accuracy and reliability.

[0008] Preferably, a damping mechanism is also provided on the central shaft. The damping mechanism includes a friction seat and two sets of sleeves. The friction seat is fixedly set at the middle position on the central shaft. The sleeves are connected to the positioning sleeve. Damping blocks are fixedly connected to the inner side of each set of sleeves. Both sets of damping blocks are adapted to the side of the friction seat.

[0009] By adopting the above technical solutions, vibrations during pedal movement can be effectively absorbed and attenuated, especially on uneven roads, reducing the transmission of vehicle bumps to the pedals, thereby improving driving comfort and operational stability.

[0010] Preferably, the damping block and the side of the friction seat are both made of wear-resistant rubber.

[0011] By adopting the above technical solutions, it is possible to ensure that the damping mechanism maintains a high coefficient of friction and wear resistance during long-term use, avoid performance degradation due to wear, and extend the service life of the overall pedal.

[0012] Preferably, the positioning sleeve has lateral protrusions on both sides, which are adapted to the internal grooves of the deflection seat.

[0013] By adopting the above technical solution, a stable engagement between the positioning sleeve and the deflection seat is achieved, preventing loosening or dislocation during pedal deflection and ensuring transmission accuracy and structural reliability.

[0014] Preferably, the bottom of the outer spring is disposed inside the spring seat.

[0015] By adopting the above technical solution, a uniform support force is provided when the pedal rebounds, avoiding spring offset or deformation, and ensuring smooth pedal operation and accurate return.

[0016] Preferably, an inner spring is provided at the bottom of the transmission rod and inside the outer spring, and the bottom of the inner spring is also provided inside the spring seat.

[0017] By adopting the above technical solution and using a dual-spring redundancy design, the jamming problem caused by fatigue failure of a single spring is prevented with the assistance of the inner spring, thereby improving the safety and durability of the system.

[0018] Preferably, the dust cover is made of rubber and has stretchable pleats.

[0019] By adopting the above technical solution, dust and foreign objects are effectively isolated from entering the internal mechanism. At the same time, the pleated design allows the pedal to extend and retract freely during movement, avoiding tearing of the cover or interference with operation.

[0020] In summary, this application has the following beneficial technical effects: it realizes bidirectional control (front pedal and rear pedal), improving the flexibility and accuracy of throttle control; the damping mechanism and dual spring design significantly reduce vibration and jamming risks, enhancing driving comfort and system reliability; the dust cover protects internal components and extends service life; the overall structure is compact and suitable for various automotive electronic throttle systems.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] A two-way control electronic throttle pedal includes a base 1, a dust cover 2 on top of the base 1, a support 3 on the dust cover 2, a front control pedal 4 fixedly connected to the support 3, and a rear control pedal 5 connected to the bottom of the front control pedal 4, enabling two-way control. A spring seat 6 is connected to the bottom of the base 1. Four sets of transmission rods 7 are arranged on the base 1, with each set of transmission rods 7 positioned in pairs at the bottom of the support 3. When the angle of the support 3 changes, the transmission rods 7 move upward or downward. An external spring 8 is also provided. Rotary seats 10 are fixedly connected to the top two sides of the base 1. A central shaft 11 is provided on the two sets of rotating seats 10. Positioning sleeves 12 are sleeved on both sides of the central shaft 11. A deflection seat 13 is provided on the positioning sleeve 12. A mounting seat 14 is provided on the deflection seat 13. The top of the mounting seat 14 is fixedly provided on the bottom of the support base 3. A magnet 16 is also provided on the deflection seat 13. A Hall sensor circuit board adapted to the magnet 16 is provided on the base 1, which can monitor the deflection signal of the magnet 16.

[0031] Furthermore, a damping mechanism 15 is also provided on the central shaft 11. The damping mechanism 15 includes a friction seat 151 and two sets of sleeves 152. The friction seat 151 is fixedly set in the middle position on the central shaft 11, and the sleeves 152 are connected to the positioning sleeve 12. Damping blocks 153 are fixedly connected to the inner side of each set of sleeves 152. Both sets of damping blocks 153 are adapted to the side of the friction seat 151. When they come into contact and rub, they can effectively absorb and attenuate road bumps, reduce vehicle vibration on uneven roads, and thus improve driving and riding comfort.

[0032] Furthermore, the damping block 153 and the side of the friction seat 151 are both made of wear-resistant rubber, which has a good frictional contact effect to improve their performance.

[0033] Furthermore, lateral protrusions are provided on both sides of the positioning sleeve 12, which are adapted to the internal groove of the deflection seat 13, so that the positioning sleeve 12 and the deflection seat 13 can be well engaged.

[0034] Furthermore, the bottom of the outer spring 8 is located inside the spring seat 6, so that when the transmission rod 7 moves downward, the outer spring 8 is compressed to prevent the control pedal from easily loosening.

[0035] Furthermore, an inner spring 9 is installed at the bottom of the transmission rod 7 and inside the outer spring 8. The bottom of the inner spring 9 is also located inside the spring seat 6. This double-spring redundancy design ensures a long service life. The outer spring 8 ensures basic support strength, while the inner spring 9 can provide additional support when necessary, preventing jamming problems caused by fatigue or damage of a single spring. This design improves the reliability and safety of the accelerator pedal, ensuring normal operation under various driving conditions.

[0036] Furthermore, the dust cover 2 is made of rubber and has retractable pleats, which can effectively protect the pedal area from dust, while also allowing for a certain degree of flexibility.

[0037] The implementation principle of this embodiment is as follows: When the user presses the front control pedal 4 or the rear control pedal 5, the support base 3 drives the deflection seat 13 to deflect around the central axis 11 through the mounting base 14; during the deflection process, the position change of the magnet 16 is detected in real time by the Hall sensor circuit board and converted into an electronic signal output to control the throttle; at the same time, the transmission rod 7 moves with the support base 3, compressing the outer spring 8 and the inner spring 9 to provide a rebound force; the damping mechanism 15 absorbs vibration through the friction contact between the damping block 153 and the friction seat 151, ensuring smooth operation; the dust cover 2 protects the internal components and prevents dust from affecting the sensor accuracy. The entire system realizes sensitive and reliable bidirectional electronic control.
