In order to achieve the technical purpose, the invention adopts the following technical scheme:
a two-way unlocking mechanism of an automobile seat backrest comprises an angle adjuster mechanism and an unlocking hand wheel, wherein the angle adjuster mechanism comprises: the angle adjuster, the unlocking arm, the limiting pin and the transmission gear; the unlocking arm is arranged on the angle adjuster through a rotating shaft, rotates around the rotating shaft and is limited by a limiting pin arranged on the angle adjuster; the unlocking arm is an integrated structure with one end provided with a toothed plate and the other end provided with an unlocking arm pin, and the toothed plate end of the unlocking arm is meshed with the transmission gear; the gear shaft of the transfer gear is fixedly connected to the angle adjuster;
the unblock hand wheel is cylinder lid structure, and its inside is equipped with rotation axis axle sleeve, hand wheel internal tooth and slurcam.
Furthermore, the rotating shaft sleeve is sleeved on the rotating shaft, rotates around the rotating shaft and is limited by a limiting pin.
Furthermore, be equipped with hand wheel internal tooth and slurcam on the unblock hand wheel lid inner edge, the hand wheel internal tooth sets up with slurcam opposite direction.
Furthermore, the inner teeth of the hand wheel are meshed with the transmission gear to drive the transmission gear to rotate; the pushing plate is contacted with the unlocking arm pin in the stroke, and pushes the unlocking arm pin to do arc motion.
Furthermore, the outer surface of the cylinder of the unlocking hand wheel is provided with an anti-skidding groove, so that the hand-holding friction force is increased.
Compared with the prior art, the invention has the beneficial effects that:
the unlocking arm pin is pushed by the rotation of the pushing plate to drive the unlocking arm to rotate clockwise, so that clockwise unlocking is realized; and the inner teeth of the hand wheel drive through the transmission gear to enable the unlocking arm to rotate clockwise, so that the counterclockwise unlocking is realized. The bidirectional adjusting and unlocking of the automobile seat backrest are realized through the same unlocking hand wheel, the structural design is compact, the operation is easy to understand, and misoperation can be avoided.
