Embodiment Construction

[0045] Embodiment one of the present invention sees attached image 3 and Figure 4. The present invention includes a power output worm 21 of the motor 10 fixed in the casing, and the power output worm 21 is composed of a worm wheel 211 and a worm shaft 30 . The drive shaft 22 of the motor is connected with the power output worm. The reduction mechanism 20 including the power output worm 21 and the first transmission gear shaft 23 transmits power to the damper drive shaft 25 through the final output gear 26 on the final output gear shaft. see Figure 4 , on the end shaft of the power output worm 21—the worm shaft 30, there is a sensing hole 31 that can pass light and be used to detect the rotating speed of the rotating member, and the light emitting parts of the light sensor 40 are respectively provided on both sides of the sensing hole 31 41 and light receiving unit 42. The light sensor 40 is connected with the vehicle controller to form a signal acquisition and processi...

Abstract

The present invention discloses a vehicle electric actuator which comprises a motor, a transmission mechanism for driving the rotation of the driven piece and a feedback inductor; wherein, the transmission mechanism comprises a rotating piece. The rotating piece is arranged with a sensing hole structure which comprises a sensing hole that allows the running-through of the light and is used for detecting the rotary speed of the rotating piece. The feedback sensing mechanism is a light sensor which is mainly composed of a light transmitting part and a light receiving part that are respectively arranged at the two sides of the sensing hole. The sensing hole is provided with a sealed sensing hole to avoid the lubricating oil in the actuator polluting the transparent object of the sensing hole. The actuator adopts the non-contact optical detecting mode for detecting the variation condition of the angle and position caused by the revolving of the motor in order to settle the technical problems of overgreat error appeared in the feedback control mode and easy abrasion of the feedback detecting device in the existing actuator. The actuator can be widely used in the positions of air conditioner throttle, head lamp, rear view mirror and the like of the vehicle in which the angle and position need to be adjusted.

Description

technical field [0001] The invention relates to an electric actuator used in automobiles. The actuator can be widely used in the positions where the angle and position need to be adjusted, such as air-conditioning dampers, headlights, and rearview mirrors of automobiles. Background technique [0002] Existing technology for the use of automobiles as actuators. Automobiles use a variety of electric actuators such as air conditioner damper control actuators, headlight angle adjustment actuators, and rearview mirror angle adjustment actuators. These actuators generally use electric motors, and the motors transmit the rotational force to the acting objects such as dampers through reduction gears and other gear transmissions. The change of the rotation angle of the motor is transmitted to the gear of the transmission device, causing the gear set to rotate, and the change of the angle and position of the gear is reflected on the measured voltage, and the potential difference is d...
