Technical Field

[0001] This utility model relates to the field of electronic throttle technology, and in particular to a waterproof dual-signal electronic throttle accelerator for new energy electric vehicles. Background Technology

[0002] When the driver presses the accelerator pedal, sensors detect the change in pedal position and convert it into an electrical signal. This signal is transmitted to the vehicle's control system, which determines the driver's acceleration intention based on the received signal and then controls the electric motor's output power to accelerate the vehicle. For example, when the pedal is pressed more deeply, the intensity of the electrical signal generated by the sensor increases accordingly, and the control system instructs the electric motor to output more power, making the vehicle accelerate faster.

[0003] Currently, there are two main types of electronic throttle accelerators for electric vehicles: 1. Resistive accelerators: These use a potentiometer as their core, changing the resistance and outputting a 0-5K signal through pedal movement. Their disadvantages include short lifespan due to mechanical friction, poor accuracy and consistency, weak waterproofing, and low reliability. 2. Hall effect accelerators: These are based on ordinary Hall elements and require two magnets to generate a 0-5V voltage signal. They suffer from complex structures, poor angle consistency, and low-temperature performance degradation, limiting the user experience. Both types share the drawback of poor environmental adaptability and insufficient waterproofing.

[0024] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4 As shown, this embodiment provides a waterproof dual-signal electronic throttle accelerator for new energy electric vehicles, including a protective housing 1, a mounting cover 101, a protective plate 102, a waterproof flange 2, multiple connectors 3, a waterproof junction box 4, a mounting post 5, a first signal component, a second signal component, and a rotating mechanism 9 connected to the accelerator pedal.

[0027] Reference Figure 1 and Figure 2In this embodiment, the waterproof flange 2 is integrally formed on the edge of the protective housing 1. The mounting cover 101 has a groove that matches the waterproof flange 2. The protective plate 102 is fixed on the positioning post in the protective housing 1. Multiple connectors 3 are all arranged on one side of the protective housing 1, and the ends of the multiple connectors 3 are flush. The waterproof junction box 4 is arranged at the ends of the multiple flush connectors 3. The mounting post 5 is integrally formed with the protective housing 1. The first signal component and the second signal component are both arranged in the mounting post 5. The rotating mechanism 9 is rotatably installed in the mounting post 5. A connecting post 8 is provided on one side of the protective housing 1 for fixing the protective housing 1.

[0028] In this embodiment, the waterproof flange 2 cooperates with the groove of the mounting cover 101 to ensure the sealing performance of the housing; the waterproof junction box 4 ensures the sealing performance of the connector 3. The rotation angle of the rotating mechanism 9 is detected by the first signal component or the second signal component.

[0029] Reference Figure 4 The first signal component includes a Hall element 6 and a ring magnet 61; the ring magnet 61 is embedded in one end of the rotating mechanism 9, the rotating mechanism 9 is rotatably connected to the axis of the mounting post 5, the Hall element 6 is disposed on the surface of the mounting post 5, and the Hall element 6 is mounted facing the ring magnet 61.

[0030] In this embodiment, when the accelerator pedal is pressed, the rotating mechanism 9 rotates by a certain angle, thereby causing the annular magnet 61 to rotate. The magnetic field strength is detected by the Hall element 6, which outputs a 0-5V electrical signal. Engineers can program the output 0-5V electrical signal to adjust the output signal, thereby giving the accelerator higher accuracy and reliability.

[0031] The ring magnet 61 includes multiple magnet blocks, the N and S poles of which are alternately arranged on the circumference of the rotating mechanism 9 to provide a magnetic field gradient that varies with the angle.

[0032] For example, a 12-level magnetic ring can be used, with the N and S poles alternating on the circumference, one magnetic pole every 30° (12 N poles and 12 S poles are set alternately).

[0033] Reference Figure 4 The second signal component includes a read head 11 and a magnetic scale 12; the magnetic scale 12 is disposed on the surface of the rotating mechanism 9, and the read head 11 is disposed on the mounting post 5, with the read head 11 facing the magnetic scale 12.

[0034] In this embodiment, when the accelerator pedal is pressed, the rotating mechanism 9 rotates by a certain angle, thereby rotating the magnetic scale 12. The reading head 11 detects the magnetic field strength and outputs a 0-5K electrical signal. Engineers can program the output 0-5K electrical signal to adjust the output signal, thereby giving the accelerator higher accuracy and reliability.

[0035] Reference Figure 3 and Figure 4 A waterproof mounting plate 7 is provided on one side of the mounting post 5. One end of the rotating mechanism 9 is rotatably mounted in the waterproof mounting plate 7. One end of the rotating mechanism 9 has a mounting groove 91 for connecting with the accelerator pedal. Waterproof rings are provided at the rotational mating positions of the rotating mechanism 9, the waterproof mounting plate 7, and the mounting post 5 to ensure sealing performance.

[0036] The rotating mechanism 9 has a first slot 92, and the inner wall of the mounting post 5 has a second slot 93. A return spring 10 is fitted onto the surface of the rotating mechanism 9, with its two ends inserted into the first slot 92 and the second slot 93, respectively. The return spring 10 ensures that the rotating mechanism 9 can promptly return to its original position when the accelerator pedal is released.

[0037] The inner wall of the mounting column 5 is provided with a limiting ring 94, and the surface of the rotating mechanism 9 is integrally formed with a limiting baffle 95. The limiting ring 94 is semi-circular.

[0038] In this embodiment, the limiting ring 94 and the limiting baffle 95 are used together. The limiting ring 94 restricts the limiting baffle 95 to rotate 180°.

[0039] When the limit ring 94 restricts the limit baffle 95 to rotate 180°, the magnetic scale 12 rotates at least half a turn around the rotating mechanism 9. This ensures that the accelerator pedal is within its normal operating range, and that the magnetic scale 12 provides sufficient angular change information to meet the accuracy requirements of signal detection and output.

[0040] In actual use, when the driver presses the accelerator pedal, the accelerator pedal drives the rotating mechanism 9 to rotate via the mounting slot 91. The rotation of the rotating mechanism 9 causes the annular magnet 61 to rotate relative to the Hall element 6, allowing the Hall element 6 to detect the continuously changing magnetic field strength and output a corresponding 0-5V electrical signal. Simultaneously, it causes the magnetic scale 12 to rotate relative to the reading head 11, which detects the change in the magnetic field of the magnetic scale 12 and outputs a 0-5K electrical signal. These two signal components detect the rotation angle of the rotating mechanism 9 from different perspectives and output the detection results as electrical signals.

[0041] After acquiring these two electrical signals, engineers process and analyze them using pre-written programs. Based on the vehicle's actual needs and performance characteristics, they precisely adjust and control the output signals. For example, they can adjust the accelerator's output power and response characteristics according to different vehicle speeds, road conditions, and driving modes, making the vehicle's acceleration process smoother and more efficient, while improving energy utilization.

[0042] To further improve the reliability and stability of the dual-signal electronic throttle accelerator, a series of protective and buffering devices are also provided in this embodiment. The waterproof flange 2 fits tightly with the groove of the mounting cover 101 to form an effective sealing structure, preventing moisture, dust, and other impurities from entering the protective housing 1 and affecting the normal operation of electronic components. The waterproof junction box 4 not only protects the connector 3 from external environmental corrosion but also ensures the safe and reliable electrical connection at the wiring point.

[0043] Furthermore, the reset spring 10 ensures that the rotating mechanism 9 quickly returns to its initial position after the accelerator pedal is released, guaranteeing the repeatability and consistency of the accelerator. The combined use of the limit ring 94 and the limit baffle 95 restricts the rotation angle of the rotating mechanism 9, preventing excessive rotation that could damage internal electronic components or affect the accuracy of signal detection.

[0044] In practical applications, this waterproof dual-signal electronic throttle accelerator for new energy electric vehicles can be widely used in various new energy electric vehicles. Its waterproof performance can adapt to various harsh working environments, such as rainy days and wet roads; the dual-signal detection mechanism improves the accuracy and reliability of the accelerator, ensuring vehicle driving safety and performance stability; at the same time, its simple and compact structure makes it easy to install and maintain, and it has high practicality and economy.
