As shown in FIG. 3, the output shaft 30 includes an output shaft body 31 and a flange portion 32, and the flange portion 32 is arranged around the output shaft body 31 and coupled to the inner peripheral wall of the first gear member 41. The output shaft 30 also includes a valve core joint 33. The output shaft body 31 has a cylindrical shape and a through hole 311 is formed inside for coupling with the connecting member 71 of the second driving module 70. The flange portion 32 extends radially from the outer peripheral wall of the output shaft body 31 and is equidistantly provided with a plurality of engagement notches 321 at the periphery. The engagement notches 321 are used for coupling to the protrusion 411 of the first gear member 41 (as shown in FIG. 5). The valve core connecting portion 33 is connected to the flange portion 32 and extends from the opening of the third receiving groove S5 of the device body 10 to below the device body 10 for connecting the valve core of the valve device.

The flange portion 32 and the valve core coupling portion 33 are respectively accommodated in the second accommodating groove S4 and the third accommodating groove S5, and are restricted by the second accommodating groove S4 and the third accommodating groove S5. The axis L1 rotates, thereby causing the output shaft 30 to rotate around the first axis L1 (as shown in FIGS. 6 and 7). The through hole 213 in the shaft body 211 of the coupling portion 21 of the input shaft member 20 is fitted to the output shaft body 31 of the output shaft member 30, and the axis of the output shaft body 31 coincides with the axis of the through hole 213, thereby the input shaft member 20 also rotates around the first axis L1. Therefore, both the input shaft 20 and the output shaft 30 rotate around the first axis L1.

As shown in FIGS. 3, 4 and 5, the power transmission module 40 includes a first gear member 41, an eccentric coupling member 42 and a second gear member 43. The first gear 41 is coupled to the output shaft 30 and rotates around the second axis L2, and the second axis L2 is parallel and deviated from the first axis L1. The input shaft 20 and the first gear 41 are relatively rotatable and eccentrically coupled to the eccentric coupling member 42.

In this embodiment, the eccentric coupling member 42 and the input shaft member 20 are integrally formed, that is, the eccentric coupling member 42 is connected to the supporting portion 22 of the input shaft member 20. In this embodiment, the eccentric coupling member 42 is a cylinder, and the second axis L2 passes through the axis of the eccentric coupling member 42, and the eccentric coupling member 42 and the shaft 211 of the coupling portion 21 are eccentrically arranged with each other, as described above , The shaft 211 is fitted to the output shaft body 31 of the output shaft 30 and rotates around the first axis L1, and the axis of the eccentric coupling 42 itself is the second axis L2, and the eccentric coupling 42 and the coupling 21 The shaft body 211 is eccentrically arranged, and the second shaft center L2 and the first shaft center L1 are eccentrically arranged. In this way, the input shaft member 20 and the eccentric coupling member 42 are integrally formed, and the first gear member 41 is rotatably sleeved on the eccentric coupling member 42 via the bearing 44, so that the input shaft member 20 and the first gear member 41 are eccentrically arranged with respect to each other. Can be rotated relatively.

The second gear member 43 is disposed in the first accommodating groove S3 of the second accommodating space S2. As described above, the stopper 50 is disposed in the accommodating recess S6 of the inner peripheral wall of the first accommodating groove S3. The stopper 50 stops the second gear member 43 so that the second gear member 43 is positioned in the first accommodating groove S3 without rotating. In this embodiment, the outer peripheral wall of the second gear member 43 is provided with a plurality of recesses 431, and the stopper 50 is engaged with one of the recesses 431. Thereby, the axis of the second gear member 43 coincides with the first axis L1. The second gear member 43 is ring-shaped, and the second gear member 43 has teeth provided on the inner peripheral wall to form inner ring teeth. The diameter of the first gear piece 41 is smaller than the diameter of the second gear piece 43, so the second gear piece 43 is arranged around the first gear piece 41. As mentioned above, the axis of the first gear member 41 coincides with the second axis L2, and the second axis L2 is eccentrically arranged with the first axis L1. Therefore, the first gear member 41 passes through the second axis L1. L2 is eccentrically arranged with the first axis L1 to mesh with the inner ring teeth of the second gear 43.

Please refer to FIG. 6, which is a cross-sectional view of the valve core driving device of FIG. 2 along the line A-A. As shown in the figure, the eccentric coupling member 42 rotates around the first axis L1, the first gear member 41 revolves around the first axis L1 along the track, and the first gear member 41 rotates around the second axis L2. Since the first gear member 41 is coupled to the eccentric coupling member 42 via the bearing 44, the first gear member 41 can rotate relative to the eccentric coupling member 42. Since the eccentric coupling member 42 is eccentrically arranged with respect to the first axis L1, the first The gear member 41 keeps meshing with the second gear member 43, and the second gear member 43 is blocked by the stopper 50 to keep it from rotating. When the eccentric coupling member 42 rotates around the first axis L1, the first gear member 41 will revolve around the first axis L1. Since the eccentric coupling member 42 will rotate around the first axis L1, the first gear member 42 is formed by the eccentric coupling member 42. The position where a gear member 41 meshes with the second gear member 43 will also change continuously as it rotates.

Please refer to FIG. 7, which is a cross-sectional view of the valve core driving device of FIG. 2 along the line B-B. 4 again, a plurality of protrusions 411 are provided on the inner peripheral wall of the first gear member 41, and the protrusions 411 of the first gear member 41 are engaged with the engagement notches 321 of the flange portion 32 of the output shaft member 30, However, the engaging notch 321 allows the protrusion 411 to move relative to the radial direction of the first gear member 41. As mentioned above, when the first gear 41 revolves around the first axis L1, the first gear 41 itself will rotate around the second axis L2, so the rotation of the first gear 41 can be engaged with by the protrusion 411 The engagement structure of the notch 321 causes the output shaft 30 to rotate. Since the output shaft 30 rotates around the first axis L1, and the first gear 41 itself rotates around the second axis L2, the engagement notch 321 allows the protrusion 411 to be opposed in the radial direction of the first gear 41 With the margin of movement, the output shaft 30 can be rotated by the first gear 41.

Please refer to FIGS. 1, 2 and 3 again. The valve core driving device 100 of the present application further includes a second driving module 70 connected to the output shaft 30. The second driving module 70 includes a connecting piece 71 and a rotating operating piece 72. The connecting piece 71 is connected to the output shaft 30, and the rotating operating piece 72 is fixed to the connecting piece 71. In this embodiment, the connecting member 71 is a long rod-shaped rotating rod, and the rotating operating member 72 is a handle. As mentioned above, the output shaft body 31 of the output shaft member 30 fits the through hole 213 in the shaft body 211 of the coupling portion 21 of the input shaft member 20, so the connecting member 71 directly extends into the output shaft body 31 of the output shaft member 30 The through hole 311 is combined with the through hole 311. The connecting member 71 may be a D-shaped shaft, and the through hole 311 may be a D-shaped shaft hole. After the connecting member 71 is coupled to the through hole 311, the output shaft 30 can be rotated by the connecting member 71 via the rotating operating member 72.

When the first driving device 60 cannot be operated due to a power failure or malfunction, the connecting member 71 can be inserted into the perforation 311, and the user manually operates the rotating operating member 72 to make the connecting member 71 drive the output shaft 30 to rotate. As shown in FIG. 6, because the input shaft 20 is combined with the first driving device 60, when the first driving device 60 cannot operate, the input shaft 20 cannot rotate, but the eccentric structure of the eccentric coupling 42 makes the first gear 41 and the second gear 43 are maintained at a constant meshing position. In addition, as shown in FIG. 7, the user manually operates the second drive module 70 to provide the torque required for the rotation of the output shaft 30. The output shaft 30 engages the notch 321 with the protrusion of the first gear 41 The engaging structure of 411 transmits the torsion force to the first gear member 41. Please refer to FIG. 6 again. Since the first gear 41 meshes with the second gear 43, the torsion force is transmitted from the first gear 41 to the second gear 43, so that the second gear 43 pushes the stopper 50. When the applied torque is greater than a predetermined value, the second gear 43 pushes the stopper 50 back and becomes a state capable of rotating relative to the device body 10, whereby the output shaft 30 can be manually rotated to rotate the valve core.

In order to achieve the above-mentioned operation mode of the stopper 50 that can stop the second gear member 43 and can be moved under the action of a predetermined force, the stopper 50 includes an engaging portion 51 and an elastic portion 52, and the engaging portion 51 is locked. With the power transmission module 40, the elastic portion 52 is coupled to the device body 10 and the engaging portion 51 in an elastically deformable manner. Please refer to FIG. 8, which is a cross-sectional view of an embodiment of a stopper of the present application. As shown in the figure, in this embodiment, the stopper 50 has a cylindrical housing 53, the engaging portion 51 is a sphere, the elastic portion 52 is a spring, and the housing 53 has an opening whose diameter is slightly smaller than that of the engaging portion. The diameter of the portion 51 is such that the engaging portion 51 can be exposed through the opening but is still restricted in the housing 53. The elastic portion 52 presses against the engaging portion 51 and applies elastic force to the engaging portion 51. The housing 53 of the stopper 50 is engaged with the accommodating recess S6 of the first accommodating groove S3, and the ball as the engaging portion 51 is abutted by the elastic force of the elastic portion 52 and engaged with the second gear member 43 The recess 431 thereby blocks the second gear member 43. When the torsion force transmitted to the second gear 43 is greater than a predetermined value and overcomes the elastic force of the elastic portion 52, the engaging portion 51 is pushed back into the casing 53 and the second gear 43 can rotate relative to the device body 10.

Please refer to FIG. 9, which is a cross-sectional view of another embodiment of the stopper of the present application. As shown in the figure, the stopper 50 is formed by bending a metal sheet, the engaging portion 51 is a protrusion, and the elastic portion 52 is an elastic sheet. The engaging portion 51 abuts and engages with the concave portion 431 of the second gear member 43 to thereby stop the second gear 43. When the torque transmitted to the second gear 43 is greater than a predetermined value, the engaging portion 51 is pressed to elastically deform the elastic portion 52 to cause the engaging portion 51 to retreat, and the second gear 43 can rotate relative to the device body 10.

In the valve core driving device 100 of the present application, the second gear 43 is stopped by the stopper 50, the first driving module 60 provides torque to the input shaft 20, and the first gear 42 drives the output shaft 30 to rotate. When the first drive module 60 is unable to operate, the second drive module 70 directly provides torque to the output shaft 30. The first gear 42 is engaged with the second gear 43 at a predetermined position to transmit the torque to the The second gear member 43 overcomes the stop member 50 to rotate, so that the second driving module 70 can directly rotate the output shaft member 30. Therefore, the valve core driving device 100 of the present application does not need to perform a clutch operation when the automatic driving is changed to manual driving.
