DETAILED DESCRIPTION OF THE INVENTION

[0024] The following clearly and completely describes the technical solution of the embodiment of the present invention in conjunction with the accompanying drawings of the embodiment of the present invention. Apparently, the embodiment described is merely some rather than all of the embodiments of the present invention. Based on the embodiment in the present invention, all other embodiments acquired by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

Embodiment

[0025] As shown in FIGS. 1-4, the embodiment of the present invention provides a manual/automatic dual-purpose clutching structure. The manual/automatic dual-purpose clutching structure includes a driving gear assembly 1, a clutching assembly (2, 4, 5) and a driven mechanical assembly (3, 6), where the driving gear assembly 1 includes a first gear 101, a second gear 102 and driving gear driving components (7, 8, 9), the first gear 101 being coaxially and fixedly connected to the second gear 102, a gear 2 of the clutching assembly (2, 4, 5) is located on one side of the second gear 102 of the driving gear assembly and meshes with the first gear 101, the driven mechanical assembly (3, 6) is located on the other side of the driving gear assembly 1, but does not make contact with the driving gear assembly, the gear 2 of the clutching assembly (2, 4, 5) rotates around an axis of the first gear 101 of the driving gear assembly 1 under the driving of the driving gear assembly 1 to mesh with a gear 3 of the driven mechanical assembly (3, 6), the clutching assembly 2 rotates around an axis of the driving gear assembly 1 under the driving of the driving gear assembly 1 to mesh with the driven mechanical assembly 3, that is, when the driving gear assembly 1 is in transmission, the clutching assembly 2 is carried to act together until the clutching assembly 2 stops rotating after the clutching assembly 2 meshes with the driven mechanical assembly 3, power of the driving gear assembly 1 is transmitted to the driven mechanical assembly 3 by means of the clutching assembly 2, so as to control a distance between the driven mechanical assembly 3 and the driving gear assembly 1, and when the clutching assembly 2 meshes with the driven mechanical assembly 3 and may not pass through a gap between the driven mechanical assembly 3 and the driving gear assembly 1, the clutching assembly 2 stops rotating along with the driving gear assembly 1.

[0026] The clutching assembly (2, 4, 5) includes a gear carrier 5, where the gear carrier 5 includes a bottom plate 501 and a top plate 504, a connecting rod 502 being fixedly connected between the bottom plate 501 and the top plate 504, the clutching 2 being located on the connecting rod 502, one side of the bottom plate 501 being sleeved at the second gear 102, and when the clutching assembly 2 rotates along with the driving gear assembly 1, that is, the gear carrier 5 also rotates along with the driving gear assembly 1, meshing between the clutching assembly 2 and the driven mechanical assembly 3 is achieved.

[0027] One side of an upper end of the top plate 504 is fixedly connected with a retaining column 503, a torsion spring 4 is arranged at the other side of the upper end of the top plate 504, one end of the torsion spring 4 abuts against the retaining column 503, when the clutching structure is in use, that is, is mounted in a corresponding housing, the other end of the torsion spring 4 acts on the housing, under an action of no external force, the clutching assembly 2 and the driven mechanical assembly 3 are kept in a disengaged state under an action of the torsion spring 4 on the gear carrier 5, in a process that the gear carrier 5 rotates along with the driving gear assembly 1, the torsion spring 4 may be pressed and accumulates elastic potential energy, and after transmission is finished, that is, the driving gear assembly 1 does not transmit the power any more, the potential energy of the torsion spring 4 is released, such that the clutching assembly 2 is disengaged from the driven mechanical assembly 3, that is, the gear carrier 5 is restored.

[0028] The driving gear driving components (7, 8, 9) include a transmission gear assembly 7 and a driving motor 9, where the transmission gear assembly 7 includes a third gear 701 and a fourth gear 702, the third gear 701 being coaxially and fixedly connected to the fourth gear 702, the fourth gear 702 meshing with the first gear 101, the transmission gear assembly 7 has an effect of speed reduction, a motor shaft is arranged at one end of the driving motor 9 in an extending manner, a worm 8 is fixedly connected to the motor shaft, the worm 8 meshes with the third gear 701, cooperation of the worm 8 and the third gear 701 also has an effect of speed reduction, and an appropriate module is selected to ensure that the worm 8 may mesh with the third gear 701, or the third gear 701 is changed into a helical gear.

[0030] A working principle is as follows: when the present invention is in use, the driving motor 9 is started, the power is transmitted to the driving gear assembly 1 by means of the transmission gear assembly 7, the driving gear assembly 1 rotates, the gear carrier 5 rotates along with the driving gear assembly at the same time, the torsion spring 5 accumulates a force, and after the clutching gear 2 meshes with the driven mechanical assembly 3, the clutching gear 2 stops rotating along with the driving gear assembly 1, and the power is transmitted to the driven mechanical assembly 3 by means of the clutching gear 2; and after transmission is finished, the gear carrier 5 is restored under an action of the torsion spring 4.
