Description
Technical Field
[0001] This utility model relates to the field of automotive electronic control technology, specifically to a high-sealing motorcycle throttle valve. Background Technology
[0002] The motorcycle throttle is a crucial component controlling the amount of air entering the engine. Located in the engine's intake system, it is controlled via a cable connected to the throttle lever or an electronic sensor. When the rider turns the throttle lever, the throttle opening changes accordingly, adjusting the amount of air entering the cylinders, thus affecting the fuel-air mixture ratio and engine output power. In traditional motorcycles, the throttle usually works in conjunction with the carburetor to ensure the optimal air-fuel mixture ratio at different engine speeds. In modern fuel-injected motorcycles, however, the throttle position sensor transmits the opening information to the electronic control unit (ECU), which precisely calculates and adjusts the fuel injection quantity and ignition timing to achieve more efficient combustion and better performance.
[0003] CN2900812Y discloses a mechanical throttle body, belonging to the intake system components of an automotive engine. It includes a throttle body, a throttle shaft, a throttle plate, a torsion spring, a swivel bracket assembly, and an idle speed valve seat. The idle speed valve seat is mounted and fixed on the throttle body, forming a bypass air passage with it. The movement direction of the stepper motor head mounted on the idle speed valve seat faces the airflow direction from the bypass air passage. While this technology meets the airflow requirements of the stepper motor, it lacks a sealing structure between the sensor and the throttle body. During use, dust, moisture, and other impurities can enter the throttle body, affecting its normal operation and posing a safety hazard to motorcycles. Therefore, this technology still has room for improvement. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a high-sealing motorcycle throttle valve to address the shortcomings of the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing motorcycle throttle body, comprising a body, a throttle shaft disposed within the body, a main channel mounted on the surface of the body, a throttle plate mounted on the throttle shaft within the main channel, a three-in-one sensor sleeved on one side of the throttle shaft, and an idle speed sensor disposed on the other side of the body. The feature is that: a first fixing surface is provided on the side of the three-in-one sensor on the body, the three-in-one sensor includes a first housing, a first sealing structure is provided between the first housing and the first fixing surface, a second fixing surface is provided on the side of the idle speed sensor on the body, the idle speed sensor includes a second housing, and a second sealing structure is provided between the second housing and the second fixing surface.
[0006] By adopting the above technical solution, by setting first and second fixed surfaces on the main body, and by using first and second sealing structures between the housings of the three-in-one sensor and the idle speed sensor and these fixed surfaces respectively, the overall sealing performance of the system is effectively enhanced. This not only prevents dust, moisture and other impurities from entering the throttle body, protecting internal precision components and reducing wear and failure rate, but also ensures that the sensor can maintain high-precision signal transmission in various complex environments. This improves the performance stability and reliability of the motorcycle and helps maintain the engine's optimal combustion efficiency, reducing fuel consumption and exhaust emissions.
[0007] The aforementioned high-sealing motorcycle throttle valve can be further configured as follows: the first sealing structure includes a first embedded groove opened on the first fixed surface; the three-in-one sensor includes a mounting positioning post and a temperature sensor head disposed on the side of the first housing facing the first fixed surface; the first fixed surface is provided with a positioning hole for mounting the mounting positioning post and a sensor mounting hole for mounting the temperature sensor head; the first embedded groove is disposed around the positioning hole and the edge of the sensor; and a first sealing element of a corresponding shape is disposed in the first embedded groove.

[0010] By adopting the above technical solution, by setting a first air circulation groove and a second air circulation groove on the second fixed surface and opening a number of air circulation holes, the gas circulation and heat exchange are effectively promoted, which helps the sensor to dissipate heat and stabilize temperature, thereby improving the sensor's response speed and accuracy. The second embedded grooves around the edges of these air circulation grooves and air circulation holes are filled with second sealing elements of corresponding shapes, which not only ensures good sealing performance and prevents the intrusion of external impurities, but also further enhances the overall protection capability of the system, and balances sealing and ventilation, thus extending the service life.
[0011] The aforementioned high-sealing motorcycle throttle valve can be further configured as follows: a third sealing groove is provided on the side of the body away from the main channel; the third sealing groove is arranged around the main channel; a third sealing element is provided in the third sealing groove; a plurality of sealing mounting holes are provided in the third sealing groove; a plurality of mounting buttons are provided in the third sealing element; and the third sealing groove and the third sealing element are fixedly connected through mounting holes and mounting buttons.

This allows the two ends of the torsion spring to be firmly connected to the two hook grooves, achieving a stable connection between the torsion spring and the throttle shaft and the rotating frame assembly. This ensures that the torsion spring can accurately transmit torque during throttle operation, helping the rider to control the throttle opening more easily. It can also effectively absorb and buffer the vibration and impact generated during operation, protecting the precision components inside the throttle from damage.
[0015] The aforementioned high-sealing motorcycle throttle valve can be further configured as follows: the swivel assembly includes a swivel body sleeved on the throttle shaft at the same end as the torsion spring, the second hook groove is provided on one side of the swivel body, a limiting abutment piece is provided on one side of the swivel body, the body is provided with an abutment end, and an abutment member for the limiting abutment piece to abut through the abutment end.
