Technical Field
[0001] This utility model relates to the field of automotive throttle valves, specifically an automotive throttle valve seat that is easy to install. Background Technology
[0002] The throttle valve, also known as the throttle body, is a key component of the automotive engine's electronic control system, installed at the front of the intake manifold. Its core function is similar to the engine's "throat," precisely controlling the airflow into the combustion chamber by changing the opening angle of the valve plate. Traditional throttle valves are mechanically connected to the accelerator pedal via a cable, while modern electronic fuel injection engines generally use electronic throttle control (ETC), where the engine control unit (ECU) intelligently controls the opening degree by driving a motor based on the driver's accelerator pedal signal and various operating data.
[0003] For example, patent announcement number CN109139271B discloses an automotive throttle body, including a throttle body with a throttle shaft fixedly disposed in the center inside the throttle body. Throttle plates are fixedly disposed on both sides of the throttle shaft. A sensor mounting plate is fixedly connected to the upper part of the throttle body. A position sensor is fixedly connected to the side of the sensor mounting plate away from the throttle body. A clamp is fixedly connected to the side of the position sensor away from the sensor mounting plate. The lower right side of the clamp is fixedly connected to the sensor mounting plate by screws. A connecting bracket is fixedly connected to the right side of the throttle body. A motor housing is fixedly connected to the side of the connecting bracket away from the throttle body. An idle speed motor is fixedly disposed in the center inside the motor housing. A torsion bar is fixedly connected to the lower part of the throttle body. This invention relates to the field of automotive parts processing and manufacturing technology. This automotive throttle body has a simple structure, is easy to disassemble and maintain, and allows for convenient adjustment of high and low idle speed positions.
[0004] In the aforementioned technologies, when installing the throttle valve and its seat, operators typically rely on manually aligning the bolt holes on the seat and valve body. Due to the lack of an effective initial positioning and guiding structure, aligning the holes in the confined space of the car's engine compartment is difficult, resulting in low installation efficiency. Therefore, there is an urgent market need to develop an easy-to-install automotive throttle valve seat to help people solve the existing problems. Utility Model Content
[0005] The purpose of this utility model is to provide an easy-to-install automotive throttle valve seat, in order to solve the problem mentioned in the background art that when installing the throttle valve and the valve seat, the operator usually relies on manually aligning the bolt holes on the valve seat and the valve body. Due to the lack of an effective initial positioning and guiding structure, it is difficult to align the holes in the narrow space of the car engine compartment, resulting in low installation efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a car throttle valve seat that is easy to install, comprising a valve seat, wherein internally threaded posts are fixedly connected to both the front and rear ends of the upper side of the valve seat, a throttle valve body is connected to the middle of the upper end of the valve seat, and connecting wing plates are fixedly connected to both the front and rear ends of both sides of the throttle valve body, each connecting wing plate is provided with a positioning through hole, and an externally threaded post is fixedly connected to the upper surface of each connecting wing plate and above the positioning through hole.
[0007] Preferably, a sealing ring is provided between the valve seat and the throttle valve body.
[0008] Preferably, the four internally threaded posts are respectively inserted into the positioning through holes of the four connecting wing plates. The connecting wing plates are connected and fixed to the internally threaded posts by bolts passing through the middle of the externally threaded posts and then inserted into the internally threaded posts.
[0009] Preferably, rectangular limiting plates are fixedly connected to one side of each of the two internally threaded posts on the upper end face of the valve seat, and rectangular limiting grooves are provided on one side of each of the two internal positioning through holes of the two connecting wing plates on one side of the throttle valve body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4 This utility model provides an embodiment of an easy-to-install automotive throttle valve seat, comprising a valve seat 1, with internally threaded posts 101 fixedly connected to both the front and rear ends of the upper sides of the valve seat 1, a throttle valve body 2 connected to the middle of the upper end of the valve seat 1, a sealing ring 103 provided between the valve seat 1 and the throttle valve body 2, connecting wing plates 201 fixedly connected to both the front and rear ends of both sides of the throttle valve body 2, each connecting wing plate 201 having a positioning through hole 202, and an externally threaded post 204 fixedly connected to the upper end face of each connecting wing plate 201 and the upper end of the positioning through hole 202, the four internally threaded posts 101 being respectively inserted into the positioning through holes 202 of the four connecting wing plates 201, and the connecting wing plates 201 and the internally threaded posts 101 being connected and fixed by bolts 3 passing through the middle of the externally threaded posts 204 and then inserted into the internally threaded posts 101.
[0024] When installing between the valve seat 1 and the throttle valve body 2, the positioning through holes 202 of the four connecting wing plates 201 on the throttle valve body 2 are respectively fitted onto the four internal threaded posts 101. The four internal threaded posts 101 are used to accurately position the four connecting wing plates 201, which facilitates the initial connection between the throttle valve body 2 and the valve seat 1 in a narrow space. Then, the four connecting wing plates 201 and the four internal threaded posts 101 are fixed together by four bolts 3, thereby fixing the valve seat 1 and the throttle valve body 2. The sealing ring 103 is used to seal the valve seat 1 and the throttle valve body 2.
[0025] Please see Figure 2 and Figure 4 On one side of the upper end face of the valve seat 1, two internal threaded posts 101 are fixedly connected to one side of rectangular limiting pieces 102. On one side of the two connecting wing plates 201 on one side of the throttle valve body 2, rectangular limiting grooves 203 are provided. When the two internal threaded posts 101 on one side of the upper end face of the valve seat 1 are inserted into the two connecting wing plates 201 on one side of the throttle valve body 2, the two rectangular limiting pieces 102 are inserted into the two rectangular limiting grooves 203 respectively.
[0026] By setting two rectangular limiting pieces 102 on two internally threaded posts 101 on one side, when the throttle valve body 2 is connected to the valve seat 1, it is ensured that the valve seat 1 can only be installed in the only correct direction, thus realizing the misplacement function. At the same time, it can assist in completing the initial positioning and improve the installation efficiency.
[0027] Please see Figure 2 The upper end of the external threaded column 204 is connected to a rust-proof cap 4. The inner wall of the rust-proof cap 4 is fixedly provided with an internal thread part 401. The rust-proof cap 4 is fitted into the outside of the external threaded column 204 and the internal thread part 401 is threadedly connected and fixed to the external threaded column 204.
[0028] By setting the anti-rust caps 4, after the connecting wing plate 201 and the internal threaded post 101 are fixed by the bolts 3, the four anti-rust caps 4 are respectively threaded onto the four external threaded posts 204, so that the anti-rust caps 4 cover the exposed part of the bolts 3 and prevent the bolts and external threaded posts 204 from rusting after long-term use.
[0029] Working principle: When using this device in a confined space, the operator can first slip the four connecting flanges 201 onto the four internal threaded posts 101 and push the throttle body 2 to close with the valve seat 1. If the throttle body 2 cannot close with the valve seat 1, it indicates that the position is incorrect (i.e., the rectangular limiting piece 102 and the rectangular limiting groove 203 are misaligned). The operator can then rotate the throttle body 2 180 degrees to close it with the valve seat 1 again, thus preventing misalignment and ensuring precise alignment. This effectively avoids the sealing ring 103 being squeezed or cut due to incorrect positioning during installation. After confirming that the alignment is correct, the bolts 3 are passed through the external threaded posts 204 and screwed into the internal threaded posts 101 and tightened to complete the firm connection between the valve seat and the throttle body. Finally, the anti-rust caps 4 are tightened onto the external threaded posts 204, and the exposed parts of the bolts 3 are covered to provide anti-rust protection. The entire process is time-saving and labor-saving, with accurate positioning, significantly improving the installation efficiency and reliability in the confined space of the engine compartment.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
