Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical watches, in particular to a kinetic energy recovery device of an automatic winding movement. BACKGROUND

[0002] The automatic winding movement is a mechanism that can automatically wind a watch. The traditional manual winding movement needs to be manually twisted by a knob or a winder to store energy to drive the watch to run. The automatic winding movement can collect energy from the wearer's daily activities to automatically wind the watch.

[0003] The automatic winding movement usually has a certain energy storage capacity and can store energy for a period of time to run the movement. However, the automatic winding movement relies on the wearer's wrist movement to generate energy and wind. If the wearer maintains a fixed posture for a long time, the wrist movement is less, and the movement cannot obtain enough swing and swing to collect energy, resulting in insufficient winding. The automatic winding movement needs enough energy to ensure stable operation. If the winding kinetic energy is insufficient, the movement cannot provide enough energy to the barrel, thereby affecting the stable operation of the movement, and the watch will become unstable, with obvious deviation or jitter phenomenon.

[0004] When the winding kinetic energy is insufficient, the watch needs additional maintenance measures, such as frequent manual winding or using a wearable rotator to wind, which increases the maintenance cost and complexity of the watch, and wastes the kinetic energy of the automatic winding movement.

[0039] The energy release assembly 3 comprises a bottom electric telescopic rod 31 fixedly installed at the bottom of the inner wall of the protection disc 21. The bottom electric telescopic rod 31 is electrically connected to the external central processing unit, and the top output end of the bottom electric telescopic rod 31 is outputted while the top output end of the top electric telescopic rod 310 is retracted. When the top output end of the bottom electric telescopic rod 31 is retracted, the top output end of the top electric telescopic rod 310 is outputted. The top end of the bottom electric telescopic rod 31 is fixedly connected with a top block 32. The middle part of the top block 32 is rotatably connected with a swing rod 33. One end of the swing rod 33 is fixedly connected with a driving torsional spring 34. The other end of the swing rod 33 is fixedly connected with a counterweight 36. The outer side end of the driving torsional spring 34 is fixedly connected with a driving block 35. The driving block 35 is rotatably connected with the swing rod 33.

[0040] The bottom electric telescopic rod 31 and the top electric telescopic rod 310 control the energy storage of the energy storage torsional spring 23 and the release of kinetic energy. The driving torsional spring 34 controls the reset of the driving block 35. The counterweight 36 helps the energy storage of the energy storage torsional spring 23. The clamping torsional spring 38 controls the reset of the clamping block 39. The clamping tooth and the tooth groove on the opposite surface of the main shaft 22 and the movable bevel gear 311 fix the position of the movable bevel gear 311 and the main shaft 22. The one-way limiting block on the fixed rod 37 ensures the one-way rotation of the rotating ratchet wheel 25.

[0041] Better, when the swing rod 33 rotates on the surface of the top block 32 under the influence of the daily movement of the wearer, the counterweight 36 swings the swing rod 33 on the surface of the top block 32 by its own gravity, and in the process of swinging the swing rod 33, the end of the push block 35 away from the top block 32 is in contact with the tooth segment of the rotating ratchet 25, and the rotating ratchet 25 and the secondary shaft 24 are rotated, at this time the secondary shaft 24 is elastically compressed by the energy storage torsional spring 23 through the synchronous belt 26 and the main shaft 22, and the clamping block 39 is pushed and rotated on the surface of the fixed rod 37 away from the rotating ratchet 25, at this time the outside end of the clamping torsional spring 38 rotates with the clamping block 39 and is elastically compressed, when the rotating ratchet 25 rotates a tooth segment and no longer contacts the clamping block 39, under the influence of the elastic expansion of the clamping torsional spring 38, the clamping block 39 is re-clamped at the gap between the tooth segments of the rotating ratchet 25, when the swing rod 33 swings in the opposite direction, the push block 35 contacts the tooth segment of the rotating ratchet 25, under the influence of the contact of the clamping block 39, the end of the push block 35 away from the top block 32 rotates towards the top block 32, at this time the outside end of the push torsional spring 34 rotates with the push block 35 and is elastically compressed, when the push block 35 no longer contacts the rotating ratchet 25, the push block 35 is reset under the elastic expansion of the push torsional spring 34.

[0042] The working principle of the above implementation is as follows:

[0043] The initialization steps are as follows:

[0044] The bottom electric telescopic rod 31 outputs at the top output end, the top electric telescopic rod 310 retracts at the top output end, the top electric telescopic rod 310 disconnects the movable gear 311 from the main shaft 22, ensuring the energy storage function of the energy storage torsional spring 23, and the clamping block 39 is clamped at the gap between the tooth segments of the rotating ratchet 25, ensuring the one-way rotation of the rotating ratchet 25.

[0045] The working operation steps are as follows:

[0046] The wearer wears the kinetic energy recovery device of the overall automatic winding machine core on the wrist and starts to move, at this time the automatic winding machine core inherent in the watch dial 11 winds the watch dial 11, like Figure 5As shown, in the process of wearer's activity, the wrist of the wearer will swing with the body of the wearer, and the activity of the wrist of the wearer is not limited to a direction, when the wrist of the wearer swings in the clockwise direction, the swing rod 33 swings in the clockwise direction on the surface of the top block 32, at this time, the pushing block 35 also swings in the clockwise direction, when the pushing block 35 swings in the clockwise direction to the position of contacting the rotating ratchet 25, the rotating ratchet 25 is pushed to rotate with the secondary shaft 24, at this time, the secondary shaft 24 is elastically compressed by the energy storage torsional spring 23 through the synchronous belt 26 and the main shaft 22, and the clamping block 39 is pushed to rotate away from the rotating ratchet 25 on the surface of the fixed rod 37, at this time, the outer side end of the clamping torsional spring 38 rotates with the clamping block 39 and is elastically compressed, when the rotating ratchet 25 rotates one tooth interval and no longer contacts the clamping block 39, under the influence of the elastic expansion of the clamping torsional spring 38 and the one-way limiting block arranged on the fixed rod 37, the rotating direction of the clamping block 39 is limited, the clamping block 39 is clamped again at the gap between the teeth of the rotating ratchet 25, at this time, the swing rod 33 tends to restore the vertical state under the action of the gravity of the counterweight block 36, at this time, the swing rod 33 rotates in the counterclockwise direction, at this time, the pushing block 35 contacts the teeth of the rotating ratchet 25, under the influence of the clamping block 39, the end of the pushing block 35 away from the top block 32 rotates towards the top block 32, at this time, the outer side end of the pushing torsional spring 34 rotates with the pushing block 35 and is elastically compressed, when the pushing block 35 no longer contacts the rotating ratchet 25, the pushing block 35 is reset under the elastic expansion of the pushing torsional spring 34.

[0047] When the wearer takes off the kinetic energy recovery device of the whole automatic winding movement at night, the kinetic energy recovery device of the whole automatic winding movement is in a stable and undisturbed state at this time, the swing rod 33 and the weight block 36 are not affected by external force to swing, the wearer controls the top output end of the bottom electric telescopic rod 31 to retract through the central processor, and the top output end of the top electric telescopic rod 310 is output. The retraction of the top output end of the bottom electric telescopic rod 31 makes the clamping block 39 descend together with the swing rod 33, at which time the clamping block 39 is no longer clamped with the tooth gap of the rotating ratchet 25. At the same time, the top output end of the top electric telescopic rod 310 drives the movable bevel gear 311 to rise, and the top electric telescopic rod 310 is clamped with the tooth groove through the clamping teeth arranged on the opposite surface of the main shaft 22. At this time, the reverse rotation of the rotating ratchet 25 is no longer limited by the clamping of the clamping block 39, and the rotation of the main shaft 22 is no longer limited in one direction through the secondary shaft 24 and the synchronous belt 26. At this time, the energy storage torsional spring 23 is elastically stretched through the main shaft 22 to make the main shaft 22 rotate, and the main shaft 22 drives the movable bevel gear 311 to rotate at the top end of the top electric telescopic rod 310. At the same time, the side wall of the movable bevel gear 311 is in meshing resistance with the fixed bevel gear 313, and the movable bevel gear 311 is rotated by the main shaft 22 to make the fixed bevel gear 313 rotate together. The fixed bevel gear 313 rotates to drive the rotating rod 312 to rotate inside the side wall of the protection disc 21 and the supporting block 314, and drives the winding rotating column 13 to rotate through the transmission of the energy release belt 315. At this time, the winding rotating column 13 is automatically wound by the wearer during the rest time, and the kinetic energy recovery of the wearer's daytime movement is achieved, which avoids the insufficient winding kinetic energy of the dial 11, the movement cannot provide enough energy to the mainspring, and further affects the stable operation of the movement, causes the watch to have obvious deviation or shaking phenomenon, ensures that the dial 11 has sufficient energy reserve, helps to keep the time of the dial 11 accurate, and saves the operation and energy input of the wearer to manually wind up every day.
