Description
Technical Field
[0001] The utility model relates to the technical field of electronic accelerator pedals for passenger cars and all-terrain vehicles, in particular to an anti-stuck suspended electronic accelerator pedal. Background Art
[0002] Cars can make our lives more convenient and improve our quality of life. The most basic function of cars is that they can be used as our means of transportation. Compared with public transportation and highways, we save a lot of time on transfers and waiting for buses. The accelerator pedal is a key device in the structure of cars. However, there are two types of existing automobile accelerator pedals: one is a mechanical cable-type accelerator pedal, and the other is an electronic accelerator pedal. The traditional cable-type pedal has low control accuracy and non-linear acceleration, resulting in high fuel consumption, and cannot be used on new energy vehicles. Although the electronic accelerator pedal can accurately control acceleration, output linearity, and high vehicle comfort, the electronic pedals currently on the market are not suitable for harsh working conditions such as mud and sand, and are prone to jamming, causing the throttle to not return to its original position. In addition, the coaxiality of the rotating parts of the pedals on the market is not easy to control, and long-term use is prone to cause eccentric wear and sticky foot feeling when refueling. Utility Model Content
[0003] The utility model aims to provide an anti-stuck suspended electronic accelerator pedal to solve the problem in the above background technology that the existing electronic accelerator pedal is easy to get stuck, resulting in the accelerator not returning to its original position, causing eccentric wear and producing a sticky feeling on the foot.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a suspended electronic throttle pedal with an anti-stuckness, comprising a pedal arm assembly, a shell assembly, an angle sensor, a first screw, and a second screw; the pedal arm assembly comprises a pedal arm, the right side of the pedal arm assembly is connected to the shell assembly, the shell assembly comprises an outer shell, the inner side of the outer shell is connected to a spring seat, the upper end of the spring seat is connected to a spring group, the left side of the outer shell is connected to a metal plate, the right side of the shell assembly is provided with an angle sensor, the angle sensor comprises a sensor outer shell, the left side of the sensor outer shell is connected to a PCBA, the left side of the PCBA is connected to a sealing cover, the left side of the sealing cover is provided with sealant, the right side of the sensor outer shell is connected to an anti-shielding cover, the right side of the angle sensor is installed with a first screw, and the left side of the shell assembly is installed with a second screw.
[0005] Preferably, shaft sleeves are provided on both sides of the pedal arm. The shaft sleeves can ensure smooth throttle feel, increase service life and avoid possible jamming under harsh working conditions.
[0006] Preferably, a rotating shaft is provided on the inner side of the pedal arm, and the rotating shaft and the pedal arm are an integrally formed structure. The coaxiality of the rotating shaft can be ensured by the integrally formed structure. At the same time, the metal plate and the outer shell are assembled together by the second screw to ensure good coaxiality of the connecting hole to prevent the pedal from being worn unevenly and stuck.
[0007] Preferably, a mounting hole boss is provided at the lower end of the shell, and three mounting hole bosses are provided. By providing three mounting hole bosses, the flatness of the mounting plane can be reduced, which not only facilitates installation but also allows for stable engagement with the mounting surface.
[0008] Preferably, the spring group includes a large spring and a small spring. The upper end of the spring seat is connected to the large spring, and the inner side of the large spring is connected to the small spring. The diameter of the large spring is larger than the diameter of the small spring. The large spring and the small spring are concentric circle structures. One end of the double spring is fixed to the upper part of the pedal arm, and the other end is fixed to the spring seat of the shell assembly. This ensures that even if one spring fails, the pedal can still rebound to its initial position. After stepping on the pedal, due to the lever principle, the spring is compressed to provide resistance. The deeper the pedal is stepped on, the greater the spring resistance. The resistance is more linear than that of a pull-wire pedal, and the foot feel is smoother and more comfortable.
[0009] Preferably, the angle sensor and the rotating shaft of the pedal arm are not in contact, and a very high-precision voltage signal can be output through the contactless design, making the durability and stability stronger than the mechanical structure.
[0010] Preferably, mechanical limits are provided on both the pedal arm and the housing assembly, through which the pedal stroke can be precisely controlled, and the design of the arm bending angle and the pedal angle of the pedal arm are ergonomic, which can effectively reduce driving fatigue.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the anti-stuck suspended electronic throttle pedal, by setting a modular pedal arm, the pedal and the middle section of the pedal arm can be customized according to the installation environment, that is, it can be straight or bent, and other components remain unchanged. By setting a modular shell, the position of the mounting hole can be customized according to the installation environment, shortening the development cycle. At the same time, the three-point boss installation is adopted, which greatly reduces the installation flatness requirement and is easy to install. By setting a modular angle sensor, it can not only be applied to throttle pedals with different requirements, but also the connection port can be replaced at any time. Compared with the traditional pedaling method, the pedal has a smooth and comfortable feel, linear resistance, precise and linear electrical signal output, good stability, not only a long service life, but also can be used in harsh working conditions, and ergonomic, can effectively reduce driving fatigue.
