Problems solved by technology
However, in the above structure, only one end of the external pawl cooperates with the ratchet when it is meshed with the ratchet, which is likely to cause the ratchet to be biased and eccentric relative to the central axis. The greater the driving force, the greater the biased load; Under normal circumstances, repeated use will cause uneven wear. To balance the force on the ratchet, two pawls can be arranged symmetrically, but it will inevitably increase the size and affect the applicability.

The invention discloses a two-way driving device for a seat height adjuster, which comprises a blocking piece, a driving plate, a ratchet and a separating piece for fixing on the body of the height adjuster, and the separating piece is provided with a transition for covering part of the ratchet The belt and the symmetrical position of the blocking piece are rotatably socketed with a group of pawls, and the pawls and the drive plate can be connected in a relatively rotatable manner; in the non-working state, the pawls are separated from the ratchet wheel, and in the working state, the drive plate can drive the pawls to revolve. The blocking sheet that blocks the rotation through the separating sheet drives the ratchet to rotate and meshes with the inner ring ratchet of the ratchet. The above-mentioned device realizes the cooperation between the ratchet and the ratchet through the blocking effect of the blocking plate and the separating plate, realizes the effect of the drive plate making the ratchet rotate in one direction, saves the range of motion of the operation, and is set on the drive plate and the blocking plate The symmetrical pawl can realize the force balance of the ratchet during the rotation. The invention also discloses a seat and a vehicle comprising the above-mentioned two-way driving device.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing, and more specifically, relates to a bidirectional drive device. In addition, the present invention also relates to a seat comprising the above bidirectional drive device and a vehicle comprising the above seat. Background technique [0002] At present, with the continuous improvement of people's living standards, the market has higher and higher requirements for the appearance and safety of various types of seat adjustment devices. [0003] The manual height adjuster of the car seat is composed of a driving part and a locking part. The operation of the driving part is to drive the operating handle to rotate clockwise from the middle position on the side of the input end, and drive the output end to rotate clockwise. When the input end reaches the limit position At this time, the output end also stops rotating, and then the operating handle returns to the middle position under th...
