If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] The flow control valve is mainly used in the automobile intake manifold. The automobile ECU controls the gas flow of the intake manifold by detecting the current throttle opening and closing state of the driver. For example, when the throttle is increased, the automobile ECU controls the flow control valve to open to increase the number of flow channels in the intake manifold to increase the intake volume; when the throttle is reduced, the automobile ECU controls the flow control valve to close to reduce the number of flow channels in the intake manifold to reduce the intake volume. The setting of the flow control valve can ensure the full combustion of gasoline.

[0032] In the related technology, the intake manifold flow controller mostly adopts a split design, that is, the valve part and the sensor part are independent components. The valve part is generally integrated in the intake manifold, and the valve is driven to open and close by an external actuator. The sensor part generally adopts the mode of an angle sensor, which independently collects control signals from the ECU and sends out execution signals and feedback signals. Since each component operates independently, there is a deviation in the structural coordination during the overall operation, which can easily cause measurement and control errors.

[0033] In response to the problems in the related technology, the utility model proposes an intake manifold flow channel control valve, which integrates the valve part and the control detection part into one. When the automobile ECU transmits the control signal to the control valve, the control valve will receive the signal and realize the rotation of the valve plate on the valve body through the motor actuator, and convert the current valve plate state into an electrical signal through the internal angle sensor and transmit it back to the automobile ECU, thereby realizing the control of the intake of the intake manifold flow channel.

[0034] Reference Figure 1 The intake manifold flow channel control valve includes a shell, and the shell is provided with an upper shell 100, a lower shell 200 and a connecting piece 300. The upper shell 100 is covered on the lower shell 200, and the connecting piece 300 is used to fix the upper shell 100 and the lower shell 200. The upper shell 100 and the lower shell 200 are generally plastic shells or metal shells. The temperature of the intake manifold is not high. Generally, the upper shell 100 and the lower shell 200 use plastic shells to reduce costs. The upper shell 100 is provided with a mounting hole, and the lower shell 200 is correspondingly provided with a mounting column. The connecting piece 300 is a mounting bushing. When the upper shell 100 is covered on the lower shell 200, the mounting bushing passes through the mounting hole and is inserted into the mounting column, and is connected and fixed by screws or bolts. In some embodiments, the connecting member 300 can be directly configured as a screw or a bolt. Compared with this embodiment, the mounting bushing used in the embodiment provided by the utility model can effectively improve the sealing effect between the upper shell 100 and the lower shell 200, and reduce the wear of the screws or bolts on the upper shell 100 and the lower shell 200.

[0035] Reference Figure 1 The intake manifold flow channel control valve further includes a driving member 400, a circuit board 410, a magnetic gear 420, a linkage, a valve plate 500 and a magnetic sensor 440. The driving member 400, the circuit board 410, the magnetic gear 420 and the magnetic sensor 440 are all arranged in the housing, the circuit board 410 is electrically connected to the driving member 400, the magnetic gear 420 is transmission-connected to the driving member 400, the valve plate 500 is rotatably arranged outside the housing and connected to the magnetic gear 420 through the linkage, and the magnetic sensor 440 is electrically connected to the circuit board 410.

[0036] It is understandable that the shell is also provided with a plug, which is arranged in the lower shell 200 and electrically connected to the circuit board 410. The plug is used to connect an external cable, and the external signal can be transmitted to the circuit board 410 in the shell through the cable and the plug.

[0037] It is understandable that the magnetic sensor 440 is a Hall sensor element, the magnetic gear 420 is provided with an arc magnet, and the Hall sensor element can detect the position change of the arc magnet. The driving member 400 is a small motor, and the output shaft of the motor can drive the magnetic gear 420 to rotate.

[0038] It can be understood that the connecting piece is a transmission shaft, the valve plate 500 is detachably arranged on the transmission shaft, the upper shell 100 is provided with a limiting portion 110, the connecting piece is passed through the limiting portion 110, and the limiting portion 110 limits the circumferential direction of the connecting piece to avoid shaking during the rotation of the connecting piece and affecting the opening and closing effect of the valve plate 500.

[0039] It is understandable that, in order to control the rotation speed of the valve plate 500 , a reduction gear 460 is further provided between the driving member 400 and the magnetic gear 420 , and the reduction gear 460 connects the output shaft of the driving member 400 and the magnetic gear 420 .

[0040] It is understandable that when the signal of the automobile ECU is transmitted to the circuit board 410 through the plug, the circuit board 410 controls the driving member 400 to rotate forward or reverse, and the driving member 400 will drive the reduction gear 460 to rotate, thereby driving the magnetic gear 420 to rotate, and the linkage member fixedly connected to the magnetic gear 420 rotates synchronously with the magnetic gear 420, and the valve plate 500 rotates with the linkage member to achieve the effect of controlling the valve plate 500 to open or close. The magnetic sensor 440 detects the position of the magnet on the magnetic gear 420, and converts the information into an electrical signal and transmits it to the automobile ECU through the plug and cable, so that the ECU can determine the current working state of the valve.

[0041] It is understandable that the valve plate 500 is provided with a plurality of reinforcing ribs 510, which are arranged along the length direction of the valve plate 500. The reinforcing ribs 510 can effectively improve the strength of the valve plate 500, and when the driving member 400 drives the valve plate 500 to rotate, the valve plate 500 body is not easily deformed, thereby reducing the occurrence of air leakage.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
