[0002] A mechanical watch is a watch that realizes the timekeeping function through the operation of a mechanical movement. It mainly relies on a mainspring to store energy, and through a series of complex gear transmission systems, escapement mechanisms, and balance wheel hairspring systems working together, it converts the energy released by the mainspring into the precise rotation of the hands to display time. It usually also has a time reporting function and can inform the time through sound, enabling the wearer to know the specific time without looking at the watch.

[0003] The existing automatic time reporting devices for mechanical watches are usually composed of a series of gears with different numbers of teeth inside the watch, which transmit power from the power source to each component for time reporting, and at the same time control the rhythm and frequency of time reporting through the gear ratio, but do not have the function of lubricating the gears. This may lead to wear of the gears inside the mechanical watch due to long-term use, thus affecting the accuracy of time reporting of the mechanical watch. Summary of the Invention

[0009] Preferably, the transmission component includes a transmission column, the outer wall of the transmission column is fixedly connected inside the second limiting plate, a transmission block is fixedly connected to the outer wall of the transmission column, and the outer wall of the transmission column is rotatably connected inside the second fixing block.

[0010] Preferably, a hole two is opened inside the connecting plate, and the connecting plate is slidably connected to the outer wall of the second limiting plate through the hole two.

[0011] Preferably, a runner is rotatably connected to the upper surface of the chassis, a hairspring is arranged on the upper surface of the runner, a pallet fork is fixedly connected to the outer wall of the runner, an escapement gear is arranged on the outer wall of the pallet fork, the tooth end of the escapement gear is meshed with a second hand gear, the tooth end of the second hand gear is meshed with a minute hand gear, the tooth end of the minute hand gear is meshed with a third transmission gear, a second transmission gear is fixedly connected to the outer wall of the third transmission gear, the tooth end of the second transmission gear is meshed with a first transmission gear, and a rotating crown is arranged on the outer wall of the first transmission gear.

[0013] Preferably, the surface of the pallet fork is polished to reduce friction, and the material of the pallet fork is composed of an anti-corrosion layer, a strengthening layer and a temperature-resistant layer.

[0014] Preferably, the material of the anti-corrosion layer is made of beryllium bronze, the material of the strengthening layer is made of high manganese steel, and the material of the temperature-resistant layer is made of titanium alloy.

[0015] Working principle: By pressing the pressing block, when the pressing block moves, it will drive the connecting column to move, and when the connecting column moves, it will drive the sealing block to move, further driving the sliding block to move. When the sliding block moves, it will drive the first limiting plate to slide on the outer wall of the sliding block through the sliding groove. When the sliding block moves, it will also cooperate with the limiting block to compress the spring. When the first limiting plate continuously slides a certain distance, it will fix the sliding block. At this time, the first hole opened inside the sealing block will slide to the oil outlet under the oil storage tray, thus achieving the effect of adding lubricating oil to the gears arranged inside the watch. When pressing the pressing block again to drive the sliding block to move, the limiting plate will reset to the initial position. At this time, the spring will release its own elastic force to reset the sliding block. When the sliding block resets, it will drive the connecting column to move, further driving the sealing block to return to the initial position, achieving the sealing of the oil storage tray to prevent oil leakage. Through the mutual cooperation among the sliding block, the sliding groove, the first limiting plate, the spring, the sealing block, and the first hole, the gears and parts inside the watch can be quickly added with lubricating oil, avoiding wear on the surface of the gears due to long-term rotational friction, thereby helping to maintain the accuracy and shape of the gears, ensuring the stability of the transmission between the gears, further making the timekeeping of the watch more accurate, and improving the reliability of time reporting.

[0016] When it is necessary to add lubricating oil to the oil storage tray, first rotate the transmission block, further driving the transmission column to rotate. When the transmission column rotates, it will drive the second limiting plate to rotate. When the second limiting plate rotates, it will be parallel to the second hole. Subsequently, hold and pull the cap outward. Through the fixed connection between the cap and the connecting plate, it is further achieved to drive the connecting plate to slide on the outer wall of the second limiting plate through the second hole, thereby achieving the removal of the cap, facilitating the subsequent replenishment of lubricating oil to the oil storage tray, ensuring that the mechanical parts inside the watch can always be lubricated, and improving the maintenance efficiency of the watch.

[0017] Due to the excellent corrosion resistance of beryllium bronze itself, it can ensure that the escapement fork will not be corroded by the external air after long-term use, thereby improving the reliability of the escapement fork during use. Since the strengthening layer is made of high manganese steel, and high manganese steel has excellent strength, it can improve the overall hardness of the escapement fork, avoiding deformation or fracture of the escapement fork caused by long-term use. Subsequently, due to the excellent weather resistance of titanium alloy, it can ensure that the watch can still operate normally and stably in high-temperature or low-temperature environments. Through the excellent properties of beryllium bronze, high manganese steel, and titanium alloy, it can not only first improve the overall wear and corrosion resistance of the escapement fork, but also improve the weather resistance of the escapement fork, thereby improving the working efficiency of the escapement fork and further improving the reliability of the watch. The present invention provides an automatic time reporting device for a mechanical watch. It has the following beneficial effects: 1. The present invention drives the connecting column to move by pressing the pressing block, and then drives the sliding block to slide. When the sliding block slides, it will drive the first limiting plate to rotate. When the sliding block slides for the first time, the first limiting plate will slide to the upper surface of the sliding block to fix the sliding block. At this time, the first hole opened inside the sealing block will be aligned with the oil outlet on the lower surface of the oil storage tray, thereby achieving the effect of adding lubricating oil to the gear components inside the watch, avoiding wear of the gears caused by long-term use and affecting the normal timekeeping effect of the watch.

[0018] 2. The present invention drives the transmission column to rotate by rotating the transmission block, and further drives the second limiting plate to rotate. When the second limiting plate rotates, the misaligned state with the connecting plate will be cancelled. At this time, pull the cap outwards. While the cap moves, it will drive the connecting plate to slide on the outer wall of the second limiting plate, thereby achieving the quick installation or disassembly of the cap, facilitating the addition of lubricating oil to the oil storage tray later, ensuring that the gear structure inside the watch can be lubricated in real time, and improving the maintenance efficiency of the watch.

[0019] 3. Through the mutual cooperation among the anti-corrosion layer, the strengthening layer and the temperature-resistant layer, the present invention achieves the effects of improving the overall strength, corrosion resistance and weather resistance of the escapement fork, reducing the probability of the watch malfunctioning, and improving the user experience.

An oil storage tray 12 is slidably connected to the upper surface of the oil control assembly 9; Specifically, first press the push block 1, and the connecting column 4 will be driven to move through the fixing effect of the push block 1 and the connecting column 4. The fixed block 2 is used to support the movement of the connecting column 4. When the connecting column 4 moves, the connecting column 4 and the sliding component 5 will drive the sliding component 5 to slide on the outer wall of the limit block 8. When the connecting column 4 moves, it will also drive the oil control component 9 to move synchronously. When the sliding component 5 slides, it will cooperate with the limit block 8 to compress the spring 7. When the sliding component 5 slides, it will drive the limit plate 6 to slide on the outer wall of the sliding component 5. When the push block 1 is pressed for the first time, the limit plate 6 will slide to the upper outer wall of the sliding component 5. At this time, the control The oil component 9 will release the sealing state with the oil storage pan 12 to achieve the effect of releasing the lubricating oil. Press the pressing block 1 again.

At this time, the oil control component 9 will be in a sealed state with the oil storage pan 12 and the oil discharge will stop. Through the joint action of the pressing block 1, sliding component 5, limit plate 6, spring 7 and oil control component 9, the outflow of the lubricating oil in the oil storage pan 12 can be freely controlled to avoid rusting of the internal parts of the dial due to long-term use, resulting in inaccurate time data and time reporting, thereby improving the reliability of the overall use of the watch.

[0024] Please see attached Figure 5 The sliding assembly 5 includes a sliding block 501, the outer wall of the connecting column 4 is fixedly connected to the outer wall of the sliding block 501, a sliding groove 502 is provided inside the sliding block 501, the limiting plate 6 is slidably connected to the outer wall of the sliding block 501 through the sliding groove 502, the outer wall of the sliding block 501 is slidably connected to the outer wall of the limiting block 8, and the outer wall of the spring 7 is arranged on the outer wall of the sliding block 501; Specifically, the slide groove 502 adopts an irregular design, and the slide groove 502 is used to limit the running track of the limit plate 6, and the spring 7 is used to quickly reset the sliding block 501. Through the joint action between the limit plate 6 and the spring 7, the overall running stability and working efficiency of the sliding assembly 5 are improved.

[0025] Please see attached Figure 1 -Attached Figure 5 The oil control assembly 9 includes a sealing block 901, the outer wall of the connecting column 4 is fixedly connected to the outer wall of the sealing block 901, a hole 902 is opened inside the sealing block 901, and the upper surface of the sealing block 901 is slidably connected to the lower surface of the oil storage pan 12; Specifically, when the connecting column 4 moves, due to the fixing effect between the connecting column 4 and the sealing block 901, the sealing block 901 will be driven to move. When the sealing block 901 moves, it will drive the first hole 902 to coincide with the lower surface of the oil storage tray 12. At this time, the lubricating oil stored inside the oil storage tray 12 will flow into the internal mechanical gears of the watch through the first hole 902, achieving the effect of lubricating the internal mechanical gears of the watch.

[0026] Please refer to the appendix Figure 6 - appendix Figure 7 Inside the oil storage tray 12, an oil pipe 11 is fixedly connected. The outer wall of the oil storage tray 12 is fixedly connected to the outer wall of the first fixing block 2. The outer wall of the oil pipe 11 is fitted with a cap 13. The outer wall of the cap 13 is fixedly connected to a connecting plate 14. The outer wall of the connecting plate 14 is fitted with a second limiting plate 15. A transmission component 16 is arranged inside the second limiting plate 15. The outer wall of the transmission component 16 is rotatably connected inside the second fixing block 10. Specifically, the user adds lubricating oil to the oil storage tray 12 through the oil pipe 11. The cap 13 is used to prevent the lubricating oil in the oil storage tray 12 from flowing out through the oil pipe 11. When the cap 13 needs to be removed, first rotate the transmission component 16. When the transmission component 16 rotates, due to the fixing effect between the transmission component 16 and the second limiting plate 15, the second limiting plate 15 will be driven to rotate. The second fixing block 10 is used to support the rotation of the transmission component 16. After the transmission component 16 drives the second limiting plate 15 to rotate, pull the cap 13 outwards. When the cap 13 moves, due to the fixing effect between the cap 13 and the connecting plate 14, the connecting plate 14 will be driven to move. Through the combined action of the transmission component 16, the second limiting plate 15, the cap 13 and the connecting plate 14, the cap 13 can be quickly disassembled, facilitating the addition of lubricating oil to the oil storage tray 12 later.

[0027] Please refer to the appendix Figure 7 The transmission component 16 includes a transmission column 161.

When the second limiting plate 15 rotates, the misaligned state with the connecting plate 14 will be cancelled. Due to the fixing effect between the connecting plate 14 and the cap 13, the cap 13 can be quickly fixed and removed, facilitating the addition of lubricating oil later.

[0028] Please refer to the appendixFigure 6 -Appendix Figure 7 A hole two 17 is provided inside the connecting plate 14, and the connecting plate 14 is slidably connected to the outer wall of the limiting plate two 15 through the hole two 17; Specifically, rotate the limiting plate two 15. When the limiting plate two 15 is parallel to the hole two 17, pull the connecting plate 14 outward at this time, thereby achieving the effect of quickly removing the connecting plate 14.

[0029] Please refer to Appendix Figure 1 -Appendix Figure 2 A runner 19 is rotatably connected to the upper surface of the chassis 3. A hairspring 18 is provided on the upper surface of the runner 19. An escapement fork 20 is fixedly connected to the outer wall of the runner 19. An escapement gear 21 is provided on the outer wall of the escapement fork 20. The tooth end of the escapement gear 21 is meshed with a second hand gear 22. The tooth end of the second hand gear 22 is meshed with a minute hand gear 23. The tooth end of the minute hand gear 23 is meshed with a third transmission gear 24. A second transmission gear 25 is fixedly connected to the outer wall of the third transmission gear 24. The tooth end of the second transmission gear 25 is meshed with a first transmission gear 26. A rotating crown 27 is provided on the outer wall of the first transmission gear 26; Specifically, when the rotating crown 27 is rotated, the power will be transmitted to the runner 19 through the first transmission gear 26, the second transmission gear 25 and the third transmission gear 24 arranged inside the watch dial, and drive the runner 19 to rotate. When the runner 19 rotates, it will tighten the hairspring 18. The escapement fork 20 is used to limit the rotation speed of the escapement gear 21 to keep it in a stable and uniform rotation state. Through the stable rotation speed of the escapement gear 21, the mechanical structure inside the watch can be made more reliable, reducing malfunctions such as jamming and misalignment caused by unstable rotation speed, and ensuring the accuracy of time display.

[0030] Please refer to Appendix Figure 1 -Appendix Figure 2 The outer wall of the escapement gear 21 is rotatably connected inside the chassis 3. The outer wall of the second hand gear 22 is rotatably connected inside the chassis 3. The outer wall of the minute hand gear 23 is rotatably connected inside the chassis 3. The outer wall of the third transmission gear 24 is rotatably connected inside the chassis 3; Specifically, the chassis 3 is used to provide stable support for the second hand gear 22, the minute hand gear 23 and the third transmission gear 24, avoiding the position deviation of the gears due to external forces or the centrifugal force generated during their own rotation, thus affecting the accuracy of power transmission and causing errors in the timekeeping of the watch.

[0031] Please refer to Appendix Figure 1 -Appendix Figure 8 The surface of the escapement fork 20 is polished to reduce friction. The material of the escapement fork 20 is composed of an anti-corrosion layer 28, a strengthening layer 29 and a temperature-resistant layer 30; Specifically, the anti-corrosion layer 28 is used to prevent the outside air from corroding the escapement fork 20, ensuring that the escapement fork 20 always maintains a good surface condition and mechanical properties, enabling it to precisely control the rotation of the escapement gear 21, thereby ensuring the accuracy of the watch's timekeeping. The strengthening layer 29 is used to improve the overall strength of the escapement fork 20, preventing the escapement fork 20 from deforming or breaking due to long-term use, achieving the effect of extending the service life of the escapement fork 20. The temperature-resistant layer 30 can improve the overall weather resistance of the escapement fork 20, avoiding changes in the shape and size of the escapement fork 20 caused by high or low outside temperatures, thereby affecting the matching accuracy with the escapement gear 21 and ensuring the normal operation of the escapement mechanism, achieving the effect of maintaining the accurate timekeeping of the watch.

[0032] Please refer to the appendix Figure 1 - appendix Figure 8 , the material of the anti-corrosion layer 28 is made of beryllium bronze, the material of the strengthening layer 29 is made of high manganese steel, and the material of the temperature-resistant layer 30 is made of titanium alloy; Specifically, since the material of the anti-corrosion layer 28 is made of beryllium bronze, and beryllium bronze has a high elastic limit and small elastic hysteresis, it can maintain stable elasticity during long-term use, is not prone to deformation, and it also has good corrosion resistance, and is not prone to rusting and corrosion even after long-term use, thereby improving the overall anti-corrosion performance of the anti-corrosion layer 28. High manganese steel itself has excellent strength, so that the escapement fork 20 will not break or deform even after long-term use, greatly reducing the probability of mechanical failures of the watch. Since titanium alloy itself has excellent weather resistance and antioxidant properties, it can work stably in high-temperature environments. At the same time, in low-temperature environments, titanium alloy can still maintain good toughness and strength and is not prone to embrittlement. Through the combined action of the anti-corrosion layer 28, the strengthening layer 29 and the temperature-resistant layer 30, it can not only improve the accuracy of the watch's timekeeping and the reliability of time reporting, but also extend the service life of the escapement fork 20, reduce the probability of watch failures, and improve the user experience.
