Technical Field
[0001] The utility model relates to the technical field of automobile accessory devices, in particular to a lightweight electronic throttle valve with a plastic shell. Background Art
[0002] The throttle is a controllable valve that controls air flow into the engine. Once air enters the intake manifold, it mixes with gasoline, diesel, and other fuels to create a combustible mixture, which then burns and generates power. It connects to the air filter above and the engine block below, making it the "throat" of the vehicle engine.
[0003] At present, a composite valve body structure is available that uses a plastic shell wrapped around a metal bushing. On the one hand, the use of the plastic shell can effectively reduce the weight of the throttle body. On the other hand, the throttle plate and the throttle shaft are rotatably connected to the metal bushing, ensuring the sealing accuracy of the throttle plate and the strength of the throttle body.
[0004] For example, the authorization number CN216894647U discloses a lightweight electronic throttle with a plastic housing, which includes a throttle body, a throttle shaft, a throttle plate, a gear transmission assembly, and a drive motor. The throttle body is composed of a plastic housing and a metal bushing. The plastic housing is provided with a valve mounting portion and a motor mounting portion. The motor mounting portion is provided with a motor mounting cavity and a gear mounting cavity. The metal bushing is embedded in the valve mounting portion. The metal bushing is provided with a throttle airway and upper and lower shaft holes. The drive motor is installed in the motor mounting cavity. The gear transmission assembly is installed in the gear mounting cavity. One end of the throttle shaft passes through the upper and lower shaft holes and is rotatably connected to the metal bushing via a bearing. The other end is connected to the drive motor via the gear transmission assembly. The throttle plate is mounted on the throttle shaft and is driven by the throttle shaft to rotate in the throttle airway. However, such a lightweight electronic throttle with a plastic housing is not convenient for removing the throttle plate for cleaning, maintenance, and replacement, and it is not convenient for quickly removing the throttle housing.
[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is inconvenient to remove the throttle plate for cleaning, maintenance, and replacement, and it is also inconvenient to quickly remove the throttle housing. Therefore, there is a need to improve the existing technology. Utility Model Content
