Description

Technical Field

[0001] This utility model relates to the field of automotive electronic control technology, specifically to a stable 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] CN206668413U discloses an automotive electronic throttle body, including a throttle body, an end cover connected to the throttle body, a DC motor and a gear transmission mechanism connected inside the throttle body. The throttle body includes a motor cavity, a gear cavity, and a gas passage. The DC motor is fixed to the motor cavity of the throttle body by a motor pressure plate and bolts, and the gear transmission mechanism is connected to the gear cavity of the throttle body. Its key feature is that the gas passage includes an upper port and a lower port, both of which are flange structures. This design reduces space requirements, improves installation efficiency, provides good sealing, and facilitates easy installation and disassembly. Accurate installation positioning ensures that no steps appear on the inner surface of the pipe connection, reducing airflow noise during engine acceleration. A control chip for controlling the DC motor is also located within the throttle body. Typically, the throttle body and the control chip are only fixed by an embedded slot. During vehicle operation, vibrations caused by bumps can loosen the internal control chip, leading to an open circuit in the electrical structure within the throttle body. 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 stable automotive throttle valve in response to the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable 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 drive structure capable of driving the rotating shaft to rotate. The drive structure includes a drive control box located on one side of the throttle body. The drive control box has a fixed housing. A connecting groove is provided on the control box housing facing the drive control box. A drive control circuit board is located within the connecting groove. The drive control circuit board is electrically connected to a conductive frame via connecting pins. The conductive frame includes a connecting bracket for fixed connection of connecting pins and a snap-fit ​​foot that engages with the control box housing. A snap-fit ​​block is provided at the end of the snap-fit ​​foot. A snap-fit ​​groove is axially provided on the control box housing. The conductive frame engages with the snap-fit ​​groove via the snap-fit ​​block. The edge of the snap-fit ​​groove forms a limiting block with the inner wall of the control box housing. A limiting groove abuts against the limiting groove is formed between the snap-fit ​​block and the snap-fit ​​foot.

[0006] By adopting the above technical solution, the connection between the conductive frame and the control box housing is enhanced by the snap-fit ​​between the conductive frame and the control box housing, ensuring the stability of electrical signal transmission. Even if bumps and vibrations occur during the use of the throttle valve, it will not loosen or shift, causing an open circuit in the electrical structure. At the same time, the setting of the limit block and the limit groove further ensures the stability of the conductive frame within the control box.

[0007] The aforementioned stable automotive throttle body can be further configured such that: the drive structure also includes a drive motor disposed within the throttle body, the drive motor includes a central shaft, the rotating shaft penetrates the throttle body and is disposed within the drive control box, the central shaft and the rotating shaft are linked together by a drive gear set, and the drive gear set is disposed within the drive control box.

[0008] Using the above technical solution, the drive motor is linked by a gear set between the central shaft and the rotating shaft. The outer casing of the housing provides protection for the drive control module and the motor, while also facilitating maintenance and repair.

[0009] The aforementioned stable automotive throttle valve can be further configured as follows: the drive gear set includes a half gear sleeved on one end of the rotating shaft located inside the drive control box; the drive control box is provided with a gear shaft; the gear shaft is sleeved with a first driven wheel; the first driven wheel meshes with the half gear; a second driven wheel is fixedly provided on one side of the first driven wheel; the central shaft is sleeved with a driving wheel; and the second driven wheel meshes with the driving wheel, causing the drive motor to drive the rotating shaft to rotate.

[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 stable 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; the half-clamping tooth portion is provided with a first abutting end and a second abutting end on the side facing the sleeve end; one end of the return torsion spring abuts against the first abutting end and the other end abuts against the second abutting end; an abutting block is provided on one side of the half-clamping tooth portion; and a connecting block for connecting to a limit post is provided axially inside the drive control box; the abutting block abuts against and limits the limit post.

[0012] Using the above technical solution, the reset torsion spring is sleeved on the outer periphery of the sleeve end. One end of the spring is connected to the first abutting end of the half-clamping tooth and the other end abuts to the second abutting end. The torsion spring ensures that the half gear can be accurately reset during operation. At the same time, the abutting block on one side of the half-clamping tooth abuts and limits the axial connecting block in the drive control box, causing the half gear to rotate and swing excessively during the reset process, thus protecting the gear from unnecessary wear and damage.

[0013] The aforementioned stable automotive throttle body can be further configured such that: the snap-fit ​​block has a connecting yoke on the side facing the drive motor, the connecting yoke has a snap-fit ​​groove, the drive motor is located inside the drive control box and has a connecting foot, the connecting foot is placed in the snap-fit ​​groove and electrically connected to the connecting yoke.

[0014] By employing the above technical solution, the tight engagement between the snap-fit ​​block and the connecting yoke ensures a robust connection between the drive motor and the conductive frame, preventing loosening or poor contact, thereby guaranteeing the stability and reliability of electrical signal transmission. The snap-fit ​​groove design allows for precise insertion and fixation of the connecting pins, further strengthening the connection's stability and facilitating quick installation and disassembly. The connecting yoke, acting as a conductive medium, not only enhances the reliability of the electrical connection but may also improve electromagnetic compatibility and anti-interference capabilities.

[0015] The aforementioned stable automotive throttle valve can be further configured such that: a sealing groove is provided around the edge of the control box housing, and a sealing ring is provided in the sealing groove.

[0016] By adopting the above technical solution, the tight fit between the sealing groove and the sealing ring effectively prevents the intrusion of external dust, moisture and harmful gases, ensuring that the electrical components and circuits inside the control box are protected from corrosion, short circuits and other damage, thereby extending the service life of the equipment.

[0017] The aforementioned stable 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.

[0018] 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.

[0019] The beneficial effects of this utility model are as follows: the connection between the conductive frame and the control box housing is enhanced by the snap-fit ​​between the conductive frame and the control box housing, which ensures the stability of electrical signal transmission. Even if there are bumps and vibrations during the use of the throttle valve, it will not loosen or shift, thus preventing the electrical structure from breaking. Attached Figure Description
