Problems solved by technology
[0008] However, the supporting part of the above scheme is supported at the bottom of the locking device, and the inner surface of the supporting part is supported by a cam, so the mechanism is relatively complicated, and the superposition error of the error caused by manufacturing tolerance and wear increases, which also leads to the inability of the locking device and the ring gear to mesh completely. It is easy to disengage the lock when the car collides or brakes suddenly, causing an accident and causing the lock

The invention belongs to the technical field of seat angle regulators and relates to a seat angle regulator with an auxiliary locking structure. The seat angle regulator comprises a gear ring, a guide plate, cams, a lock block and a main control panel. One side of the lock block is provided with an auxiliary lock block body with a transverse supporting lock block body. An oblique supporting face is arranged at the upper end of the head portion of the auxiliary lock block body. The side face, opposite to the auxiliary lock block body, of the lock block is provided with a supporting concave part. An abutting oblique face which abuts against the oblique supporting face is arranged at the upper end of the supporting concave part. The upper end face of the auxiliary lock block body is provided with a third protrusion. A second guide hole is formed in the main control panel. The third protrusion is slidably arranged in the second guide hole. The main control panel rotates and drives the auxiliary lock block body to be inserted into or be separated from the supporting concave part of the lock block through the third protrusion. The stability and safety of locking of the lock block and the gear ring are good, and accordingly the accuracy stability and safety of the angle regulator are good.
Description
technical field [0001] The invention belongs to the technical field of automobile seats, in particular to a seat recliner with an auxiliary locking structure. Background technique [0002] A traditional recliner consists of a ring gear, a guide plate, a cam and a locking device. The ring gear has accommodation recesses on its inner surface, and inner gear teeth are formed on edge portions of the accommodation recesses. The guide plate is connected to the inner surface of the ring gear, and a plurality of guide blocks (guide blocks) protrude from the inner surface of the guide plate. Two facing guide blocks define a locking device guide recess. The cam is placed between the guide plate and the ring gear, and the cam is sleeved with a joystick rotation shaft at its center. Outer gear teeth are formed on the outer peripheral surface of each locking device. [0003] In the conventional recliner having the above structure, when the joystick rotation axis rotates in the clockw...
