The basic function of the intake manifold of the gasoline engine is to mix gasoline and air into a 'mixed gas' according to a certain proportion, and the mixed gas is distributed to each cylinder of the engine to ensure that the fuel gas is fully combusted. Intake manifold structure is complicated, and the majority is made by the aluminum alloy, and the inner wall is coarse, can't guarantee the manifold of gas tightness, in the use, can greatly reduced performance, can't satisfy normal functional requirement, causes the noise big, and fuel burning is not abundant, and exhaust emission is many scheduling problem, directly influences the efficiency and the environmental protection of engine. And an intake manifold flow passage controller (IMRC) electronically controls opening or restricting of intake passages of the engine according to the load and speed of the engine. Under the condition that the engine is in a low rotating speed state, the IMRC is in a closed state at the moment, so that less air can enter the engine, and the oil consumption is lower. At high engine speeds, where the IMRC opens a valve, the air available to the engine increases, thereby increasing the power output of the engine. Therefore, unnecessary fuel oil waste in an idling state is avoided through controlling the air inflow of the intake manifold, and the purposes of energy conservation and emission reduction are achieved.

In addition, no matter the motor adopted by the existing intake manifold flow channel controller in a contact structure or a non-contact structure is protected during idling, when the intake manifold flow channel valve is controlled to reach an opening state and a closing state, if the motor drives a load to rotate, the temperature of the motor is easily increased, the burden of a transmission part is increased, the phenomena of motor blockage and transmission part blockage can occur, the service life of the motor is influenced, and the transmission part is broken and the motor is burnt seriously.

The magnetic coupler mainly comprises a first metal plate, a wear-resistant gasket, a magnet and a knurled bushing. The input gear and the second metal plate are integrally formed in an injection molding mode, and the input gear and the motor rotating shaft are in a loose fit state, so that the motor rotating shaft cannot directly drive the input gear to rotate. Knurling bush and magnet are integrative injection moulding, and the knurling bush is the tight matching with the motor axis of rotation and is favorable to driving magnet rotation, and first metal sheet then pastes on magnet, strengthens the magnetic field intensity of magnet. The wear-resistant gasket is arranged between the input gear and the magnet, plays a role in increasing friction force and is beneficial to the magnet to drive the input gear to rotate. The magnetic coupler is an important structure of gear set transmission, is used as a transmission bridge of a motor rotating shaft and an input gear, and mainly is used for transmitting the torque force of the motor rotating shaft to the input gear by an auxiliary motor so as to drive the whole gear set to work. In addition, the magnetic coupler structure is also a very important protection mechanism of the gear set, can reduce the burden of the gear set to prevent the occurrence of tooth breakage, can provide buffer for the motor, and prevents the motor from being stuck, thereby prolonging the service life of the motor.

As shown in fig. 7, the gear set includes a high-speed gear 18 meshed with the input gear, an intermediate gear 19 meshed with the high-speed gear, a low-speed gear 20 meshed with the intermediate gear, and a sector gear 21 meshed with the low-speed gear; the output shaft is the central shaft of the sector gear, and the motor amplifies the rotation torque of the sector gear through one stage of the gear set, so that the torque is output from the output shaft. The overall operation of the gear set is mainly: the motor rotates to drive the input gear to rotate through the magnetic coupler, the input gear is meshed with the high-speed gear to drive the high-speed gear to rotate, the high-speed gear is meshed with the intermediate gear to drive the intermediate gear to rotate, the intermediate gear is meshed with the low-speed gear to drive the low-speed gear to rotate, the low-speed gear is meshed with the sector gear to drive the sector gear to rotate, the central shaft of the sector gear is an output shaft and drives the output shaft to rotate, and the motor amplifies the rotation torque of the motor through the primary stage of the gear set, so that the output of the rotation angle and the torque is realized.

As shown in fig. 10, 11 and 12, the stopper assembly includes a first stopper 22 located on one side of the clockwise rotation direction of the sector gear and a second stopper 23 located on one side of the counterclockwise rotation direction of the sector gear, and both the first stopper and the second stopper are disposed on the inner wall of the controller housing. The rotation of the motor drives the sector gear to rotate through the input gear, the high-speed gear, the intermediate gear and the low-speed gear, and the sector gear has certain rotation limiting requirements. The rotation limit angle of the sector gear determines the rotation angle of the gear set output.

As shown in fig. 10, the gear train and the like are mounted in the original mounting position state in the controller case.

As shown in fig. 11, the intake manifold is in an open position. When control circuit control motor clockwise rotation, sector gear also follows clockwise rotation, and this action lasts until sector gear reaches the position of first stopper, receives the restriction of first stopper and stall, and the maximum angle that sector gear clockwise turned at this moment is 30 degrees. Meanwhile, the magnetic coupler plays a key role under the condition, because the output gear stops rotating, the input gear is in a corresponding static state (the friction force is not enough to drive the gear to rotate), and the magnetic coupler which drives the input gear by the friction force does not have the phenomenon of jamming but rotates normally, so that the jamming of the motor can be prevented, and the motor can be effectively protected.

As shown in fig. 12, the intake manifold is in a closed position. When control circuit control motor anticlockwise rotated, sector gear also followed anticlockwise rotation, this action lasts until sector gear reaches the second stopper position, receives the restriction of second stopper and stall, and sector gear anticlockwise pivoted maximum angle this moment is 60 degrees. In a similar way, the magnetic coupler which drives the input gear by means of friction force does not have the phenomenon of jamming at the moment but rotates as usual, so that the jamming of the motor can be prevented, and the motor can be effectively protected.

The Hall element comprises a Hall support 24 arranged on the inner wall of the controller shell and a Hall sensor 25 arranged on the Hall support, wherein the magnetic induction surface of the Hall sensor is opposite to the magnetic ring in a non-contact manner and can induce the magnetic pole change of the magnetic ring to realize corresponding signal output.

The control circuit is an H-bridge control circuit arranged on a circuit board 37 in a controller shell, and the H-bridge control circuit controls the current flow direction of the H-bridge control circuit by controlling the conduction of four triodes, so that the positive and negative rotation of the motor is controlled.

As shown in fig. 15, when the transistors a and D are turned on simultaneously, the current of the H-bridge control circuit flows from a to D, and the motor is driven to rotate clockwise, that is, the motor rotates clockwise.

As shown in fig. 16, when the transistors B and C are turned on simultaneously, the current of the H-bridge control circuit flows from C to B, and the motor is driven to rotate counterclockwise, i.e., the motor rotates reversely.

The working process of the H-bridge control circuit is as follows: the logic circuit is adopted to control the conduction of the triode, two NOT gates and four AND gates are used to achieve the expected effect, and the principle is as follows: as shown in fig. 17, when the signal L is 0, and the signal r is 1, a and D can be turned on simultaneously, and the current flows from a to D through the motor, and the motor rotates clockwise. As shown in fig. 18, when the signal L is 1, and the signal r is 0, B and C can be turned on simultaneously, and the current flows from C to B through the motor, and the motor rotates counterclockwise.

When the Hall sensor faces to the S pole of the magnetic ring, the signal output of the Hall sensor is low level; when the Hall sensor faces to the opposite side of the N pole of the magnetic ring, the signal output of the Hall sensor is high level. When the air inlet manifold flow channel controller is opened, the gear set drives the output shaft to rotate clockwise to reach the opening position, and at the moment, the Hall element detects that the magnetic pole of the magnetic ring is the S pole, and the signal is low level. When the opening state of the air inlet manifold flow channel controller is released, the gear set drives the output shaft to rotate anticlockwise to reach a closed position, the Hall element detects that the magnetic pole of the magnetic ring is an N pole, and the output signal is high level. While the rotation of the intake manifold channel controller from the open position to the closed position is for the entire response time of the intake manifold channel controller, the theoretical output waveform of the intake manifold channel controller is shown in fig. 14.

The controller shell is formed by assembling a top shell 26 and a bottom shell 27, a first bracket 28 and a second bracket 29 which are mutually staggered and stacked are arranged at the bottom of the bottom shell, and a first supporting arm and a second supporting arm are arranged on the second bracket through PP bushings 30; a gasket 31 is arranged between the top shell and the bottom shell and used for enhancing the mounting matching effect and the sealing performance.
