Description

Technical Field

[0001] This utility model relates to the field of automotive electronic control technology, specifically to a high-sealing automotive throttle valve. Background Technology

[0002] The throttle body is a key component of a car's engine system. Located in the intake manifold, its primary function is to control the amount of air entering the engine. By adjusting the throttle's opening and closing, the ratio and quantity of the air-fuel mixture can be precisely controlled, thus affecting engine performance indicators such as power, RPM, and fuel consumption. The throttle body is typically controlled by the driver via the accelerator pedal to meet different driving needs. Modern cars also often feature electronic control systems for their throttle bodies, enabling even more precise control.

[0003] CN106907249B discloses a novel electronic throttle body for automobiles. One end face of the cover plate has a groove, and two electrode posts and a mounting base are installed on the end face of the groove. Two electrodes are located within the two electrode posts. Several electrical connectors are fixed to the end face of the groove using a secondary molding process, and several electrical connectors are installed on the side of the mounting base. A position sensor is installed on the mounting base using thermoforming resin, thermal riveting, or thermally conductive filling. The electronic throttle body base includes a throttle valve plate, a rotating shaft, a DC motor, and a gear set. The installation of the position sensor and mounting base is simplified. One side of the throttle body needs to be connected to a vehicle component. However, this technology lacks a sealing structure for the throttle body, making it susceptible to water and dust ingress during use, which can damage and affect the electronic equipment inside the throttle. 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 automotive 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 automotive throttle body, comprising a throttle body, a valve plate, a throat, and a rotating shaft. The throat is located on one side of the throttle body and penetrates through it. The valve plate is fixedly connected to the rotating shaft and positioned at the bottom of the throat. The throttle body has a driving structure capable of driving the rotating shaft to rotate. The throttle body is characterized by: a sealing surface on one side, a sealing groove formed on the sealing surface, the sealing groove surrounding the throat, a sealing ring within the sealing groove, several snap-fit ​​blocks along the edge of the sealing ring, several embedded grooves for the snap-fit ​​blocks to be embedded in the sealing groove, several abutment blocks on the outer periphery of the sealing ring, the diameter of the sealing groove being larger than the diameter of the sealing ring, the sealing ring and the sealing groove being interference-fitted through the abutment blocks, and the surface of the sealing ring also having an adaptation groove capable of accommodating different diameters.

[0006] The above technical solution incorporates a sealing ring embedded in the sealing groove. The combination of the sealing ring and the sealing groove significantly enhances the sealing performance when the throttle body is connected to automotive components. This prevents dust particles from entering the throttle body and damaging internal electronic equipment during use. Furthermore, the sealing ring has a snap-fit ​​block on its edge that fits tightly with the embedded groove, ensuring the stability and sealing effect of the sealing ring during installation. The abutment block on the outer periphery of the sealing ring and the sealing groove are connected by an interference fit, further improving the reliability of the seal. The surface of the sealing ring has an adaptation groove that accommodates different diameters, providing space for the sealing ring to be squeezed inward. This allows the throttle body to adapt to various throat sizes, improving its versatility and applicability.

[0007] The aforementioned high-sealing automotive throttle body can be further configured as follows: the drive structure includes a drive control box disposed on one side of the throttle body and a drive motor disposed within the throttle body.

[0010] By adopting the above technical solution, the meshing of the half gear with the first driven gear and the further meshing of the second driven gear with the driving gear form a gear transmission. The reasonable layout of the gear shaft and gears enhances the structural compactness and reliability of the system, reduces friction and energy loss between components, and improves transmission efficiency.

[0011] The aforementioned high-sealing automotive throttle valve can be further configured as follows: the half gear includes a sleeve end sleeved on the rotating shaft and a half-clamping tooth portion disposed on one side of the sleeve end; a return torsion spring is sleeved on the outer periphery of the sleeve end; a first abutting end is formed between the half-clamping tooth portion and the sleeve end; a stop block is provided on the inner wall of the drive control box; one end of the return torsion spring abuts against the first abutting end and the other end abuts against the stop block; a limiting block is provided on one side of the half-clamping tooth portion; a connecting block for connecting to a limiting post is provided axially inside the drive control box; the limiting block abuts against and limits the limiting post.

One end of the spring is connected to the first abutting end of the half-clamping tooth part, and the other end abuts against the stop block on the inner wall of the drive control box. The torsion spring ensures that the half gear can be accurately reset during operation. At the same time, the limiting block on one side of the half-clamping tooth part abuts against the axial connecting block inside the drive control box to limit the half gear from excessive rotation and oscillation during the reset process, thus protecting the gear from unnecessary wear and damage.

[0013] The aforementioned high-sealing automotive throttle body can be further configured as follows: the drive control module includes a connection slot disposed on the side of the control box housing facing the drive control box, the connection slot is provided with a drive control circuit board, the drive control circuit board is electrically connected to a first pin, the outer periphery of the control box housing is provided with a connection port, the first pin extends into the connection port, the drive control circuit board is also provided with a second pin, the drive motor is located inside the drive control box and is provided with a connection foot, the second pin is electrically connected to the connection foot.

[0014] Using the above technical solution, the drive control circuit board is placed in the connection slot of the control box shell, and is electrically connected to the external device through the first pin, while the second pin is used to achieve electrical connection with the connection pin of the drive motor.

[0015] The aforementioned high-sealing automotive throttle body can be further configured such that: the throttle body is provided with a plurality of connecting ears on the outer periphery of the throat, and the connecting ears are provided with connecting holes for connection with automotive components.

[0016] By adopting the above technical solution, the setting of the connecting ear and connecting hole ensures a stable connection between the throttle body and other automotive components. The design of the connecting ear makes the installation and removal of the throttle body more convenient, improving maintenance efficiency and operability.

[0017] The beneficial effects of this utility model are as follows: a sealing ring is embedded in the sealing groove. The setting of the sealing ring and the sealing groove greatly enhances the sealing performance when the throttle body is connected to the car parts. When the throttle is in use, dust particles are prevented from entering the throttle and damaging the internal electronic equipment. In addition, the edge of the sealing ring is provided with a snap-fit ​​block that fits tightly with the embedded groove, ensuring the stability and sealing effect of the sealing ring during the installation process.
