Problems solved by technology

[0005]1. Most of the power control for opening and closing the door is mechanical operation, which is inconvenient and inaccurate;
[0006] 2. Some products use motors as the control power, but the motors generally have two directions of forward and reverse, and the direction conversion makes the structure complicated;
[0007]3. In order to keep the door of the valve in the horizontal position when the vehicle is at idle, a return device such as a torsion spring is required, which not only increases the structural burden, but also has the disadvantage of affecting the action of the valve due to fatigue of the torsion spring;
[0008]4. Due to the complexity of the power control system and the existence of the throttle plate return device, it not only increases the manufacturing cost, but also brings hidden dangers to the reliability of the product

Embodiment 1

[0029] An automobile electronic throttle valve, comprising a base 1, a main air passage 4 installed on the main body of the base, and a valve 8 installed in the middle of the inner cavity of the main air passage, the valve includes a door shaft 81 and a door sheet 82, the automobile The electronic throttle is equipped with an electric control mechanism to control the opening and closing of the valve and a damping device for keeping the valve door in a horizontal state when the vehicle is in an idle state; the electric control mechanism is installed on one side of the base, including a micromotor 5 And transmission gear, described micro-motor 5 is connected with the door rotating shaft 81 transmission gear of valve 8 through transmission gear, and described micro-motor is one-way motor; Described transmission gear comprises driving wheel 6, intermediate wheel 3 and driven wheel 2, and described The driving wheel is connected with the rotating shaft of the micro-motor, the driven...

Embodiment 2

[0033] An automobile electronic throttle, its structure is basically the same as that of Embodiment 1, the difference is: the transmission gear has no intermediate wheel, and only includes a driving wheel 6 and a driven wheel 2, and the driving wheel is connected with the rotating shaft of the micro-motor, The driven wheel is connected to the door shaft of the valve, and the driven wheel 2 is meshed with the driving wheel 6. The stop device is installed on the base of the driven wheel 2 side: including ratchet 71 and ratchet shaft 72, one end of the ratchet Rotate and connect around the ratchet shaft, and the other end elastically meshes with the gear teeth on one side of the driven wheel.

[0034] Above-mentioned embodiment 1~embodiment 2 is one of preferred embodiments of the present invention, as the transformation of above-mentioned embodiment 1-embodiment 2:

[0035] The door piece of the valve can also be combined with the door shaft into a whole by riveting, welding, tw...

Abstract

The invention discloses an automobile electronic throttle valve which comprises a main air passage, a valve, an electric control mechanism capable of controlling opening and closing of the valve and a damping device capable of enabling the valve piece of the valve to be in the horizontal state, wherein the damping device comprises retainers B mounted on the two sides of the valve piece and a retainer A mounted in the inner cavity of the main air passage; when an automobile is in an idling state, the valve piece is kept in the horizontal state under the action of the damping device; the electric control mechanism comprises a micromotor and a transmission gear; the micromotor is a one-way motor; the transmission gear is provided with a turn-stopping device capable of preventing reverse rotation. The automobile electronic throttle valve is convenient and accurate to operate and control; the micromotor is the one-way motor, so that counterforce impact can be avoided, the structure is simplified, the number of controlling devices and controlled devices is reduced, loss of parts is reduced, and the service life of the motor is prolonged; the turn-stopping device can prevent the valve from moving due to vibration caused by external force impact; in the idling state, the damping device enables the valve piece of the valve to be kept in the horizontal state so as to ensure that an engine does not flame out, so that the fuel consumption is decreased, and the reliability is improved.

Description

technical field [0001] The invention relates to an automobile part, in particular to an automobile electronic throttle. Background technique [0002] The automobile throttle is an important part of the engine, including the base. There is a main air passage on the main body of the base. The inlet is to receive the filtered clean air. The outlet is connected to the engine intake manifold. There is a door in the middle of the main air passage. The rotating shaft drives the door to rotate to control the amount of air intake. [0003] When the car is running, the throttle will open the valve according to the driver's intention (the size of the valve opening is determined according to the driver's intention) to control the speed of the car, whether it is fast, slow or idling; Even at idling state) there will be some negative pressure to make the valve deflect. If the valve is opened too large when the vehicle is idling, it will increase the fuel consumption of the car, and if th...
