SEAT ANGLE REGULATOR AND SEAT WITH SAME

摘要

Disclosed are a seat angle regulator and a seat. The seat angle regulator comprises an inner toothed plate with an inner toothed ring, an outer toothed plate with an outer toothed ring, a wedge block, an eccentric wheel, and a drive component, wherein the inner toothed plate is engaged with the gears of the outer toothed plate, a shaft shoulder is formed in the middle of the inner toothed plate, and the eccentric wheel is sheathed on the outer circumferential face of the shaft shoulder. The drive component comprises a drive cam and a rotating shaft, with one end of the rotating shaft fixedly connected with the middle of the drive cam and the other end penetrating through the eccentric wheel and the shaft shoulder in succession and fixed on the outer end face of the inner toothed plate axially via a locating connector.

1. A seat angle regulator comprising:
a gear transmission mechanism comprising an inner toothed plate with an inner toothed ring, an outer toothed plate with an outer toothed ring, and an eccentric wheel with a wedge block, wherein the inner toothed ring of the inner toothed plate is engaged with the outer toothed ring of the outer toothed plate, a hollow shaft shoulder is formed in a middle of the inner toothed plate, and the eccentric wheel is rotatably sheathed on an outer circumferential surface of the shaft shoulder; and a drive component comprising a drive cam and a hollow rotating shaft, wherein one end of the rotating shaft is fixedly connected with a middle portion of the drive cam, the other end of the rotating shaft penetrates through the eccentric wheel and the shaft shoulder sequentially and is axially fixed on the inner toothed plate via a locating connector, and the rotating shaft is connected with the shaft shoulder in a clearance fitting manner, wherein a resistance torque structure for transmitting torque is provided on a surface of the drive cam and a surface of the eccentric wheel that is opposite to the surface of the drive cam, and the resistance torque structure is configured to, when the drive cam is driven, transmit a driving torque acting on the drive cam to the eccentric wheel to drive the eccentric wheel to synchronously rotate and realize a torque transmission to the gear transmission mechanism.
