The ratchet opening and closing driving mechanism for the invisible handle is characterized in that: the set of pawl pins includes three pawl pins, each evenly distributed about the central axis of the drive wheel.
The utility model discloses control drive cam by ratchet structure and accomplish drive operation, will drive the reset torsion spring when drive gear begins clockwise rotation and save elastic potential energy gradually, because drive gear and drive wheel have consequently driven the drive wheel clockwise rotation simultaneously through splined connection, one-way pawl supports the ratchet all the time in order to prevent ratchet rotation simultaneously, and the pawl in the drive wheel can't drive ratchet this moment. Only when the driving gear rotates for a certain angle, the reset torsion spring starts to rotate anticlockwise under the action of continuous elastic potential energy, at the moment, the ratchet wheel starts to rotate anticlockwise under the driving of the pawl in the driving wheel, and the opening and closing driving of the invisible handle is completed through the reciprocating circular rotation of a certain angle.
The utility model discloses a ratchet structure controls drive cam and accomplishes the drive operation, and the operation is smooth and easy, reliable and stable.
The utility model discloses following beneficial effect has: compact structure, smooth operation, stability and reliability.

Detailed Description
The invention is further illustrated by the following specific examples.
Example 1
A ratchet opening and closing driving mechanism for an invisible handle comprises a driving gear front shell 1, a base rear cover 13, a reset torsion spring 2, a driving gear shaft 3, a driving gear 4, a driving wheel 5, a ratchet 6, a one-way pawl pin 7, a one-way pawl 8, a one-way pawl torsion spring 9, a pawl pin 10, a pawl 11 and a pawl reset torsion spring 12, and has the specific structure as shown in the figure:
the base rear cover 13 covers the driving gear front shell 1 to form a mounting cavity; one end of the reset torsion spring 2 is clamped in a hole on the side surface of the driving gear 4; the other end of the reset torsion spring 2 is clamped into a torsion spring groove 14 of the driving gear front shell 1, and the reset torsion spring 2 is sleeved on the driving gear shaft 3; the driving wheel 5 is sleeved on the driving gear shaft 3 and is in splined connection with the driving gear 4, a group of at least two pawl pins 10 are inserted into holes in the inner side surface of the driving wheel 5 to form interference fit, each pawl reset torsion spring 12 and each pawl 11 are respectively sleeved on the pawl pins 10 to form movable fit, the one-way pawl pin 7 is inserted into a hole in the inner side of the base rear cover 13 to form interference fit, the one-way pawl torsion spring 9 and the one-way pawl 8 are respectively sleeved on the one-way pawl pin 7 to form movable fit, and the ratchet 6 is respectively sleeved on the driving gear shaft 3 and in the driving wheel 5 and the base rear cover 13 to form movable fit.
In this embodiment: the set of pawl pins 10 comprises three pawl pins 10, each pawl pin 10 being evenly distributed around the central axis of the drive wheel 5.
When the present embodiment is assembled, as shown in fig. 2: firstly, one end of a reset torsion spring 2 is clamped into a hole on the side surface of a driving gear 4, and the other end of the reset torsion spring is clamped into a torsion spring groove 14 of a front driving gear shell 1 and is respectively sleeved on a driving gear shaft 3; as shown in fig. 3: then, a driving wheel 5 is sleeved on a driving gear shaft 3 and is in spline connection with a driving gear 4, then a group of three pawl pins 10 are inserted into holes in the inner side surface of the driving wheel 5 to form interference fit, and then three pawl reset torsion springs 12 and pawls 11 are respectively sleeved on the pawl pins 10 to form movable fit; then the unidirectional pawl pin 7 is inserted into a hole on the inner side of the base rear cover 13 to form interference fit, the unidirectional pawl torsion spring 9 and the unidirectional pawl 8 are respectively sleeved on the unidirectional pawl pin 7 to form movable fit, and then the ratchet 6 is respectively sleeved on the driving gear shaft 3 and the driving wheel 5 and the base rear cover 13 to form movable fit.
