[0002] When an automatic watch is worn, the barrel is wound by the rotation of the automatic hammer. The design requires that the automatic hammer obtains a sufficiently large static moment. Under the same other conditions, the larger the static moment, the smaller the braking angle, and the higher the winding efficiency.

[0003] Traditional automatic winding mechanism such as Figure 1 As shown, the main automatic transmission gear train is fixed between two separate bridges. Figure 2 As shown, the traditional automatic hammer is fixed on the automatic clamping plate, which fixes both the transmission wheel train and the automatic hammer, and the position for fixing the automatic hammer is raised, i.e., the first raised portion 11, which increases the thickness of the automatic clamping plate, thereby affecting the thickness of the entire movement. Therefore, designing a structure that can reduce the thickness of the automatic part by using limited axial space without changing the automatic hammer and realize winding becomes a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the present invention, the automatic winding mechanism of a mechanical watch and the mechanical watch of the present invention are further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 2 As shown, a part of the transmission wheel of the traditional automatic winding mechanism is fixed between the automatic upper plate 1 and the automatic lower plate 12, and a part is fixed between the main plate 2 and the automatic upper plate 1. This not only increases the thickness of the entire automatic winding part, but also affects the consistency of transmission due to the separate fixing of the transmission wheels, further affecting the transmission accuracy of the automatic winding part.

[0027] like Figure 3-Figure 4As shown, the automatic winding mechanism of the mechanical watch of the present invention comprises an automatic clamping plate 1, a main clamping plate 2, an automatic hammer assembly 3, a hammer wheel assembly 4, a transmission assembly and a winding ratchet 10. The automatic hammer assembly and the hammer wheel assembly 4 are riveted together as one body. The automatic hammer assembly 3 and the hammer wheel assembly 4 are fixed to the main clamping plate 2 through a bearing frame 5. The hammer wheel assembly 4 is engaged with the transmission assembly. The transmission assembly is rotatably arranged between the automatic clamping plate 1 and the main clamping plate 2. The transmission assembly is engaged with the winding ratchet 10. The winding ratchet 10 winds the mainspring 9 through the barrel shaft 11. The automatic winding mechanism fixes the automatic hammer assembly 3 between the main clamping plate 2 and the automatic clamping plate 1 through the bearing frame 5, which reduces the thickness of the entire automatic winding part and improves the transmission accuracy of the automatic winding mechanism. By directly fixing the transmission assembly to the main clamping plate 2, the thickness of the automatic winding mechanism and the transmission accuracy of the automatic winding mechanism are greatly reduced.

[0028] The automatic hammer assembly 3 is riveted with the hammer wheel assembly 4, and the hammer wheel assembly 4 is composed of a hammer wheel and a bearing riveted together. The automatic hammer assembly 3 and the hammer wheel assembly 4 are fixed to the main plate 2 through a bearing frame 5. The center of the bearing frame 5 is rotatably connected to the automatic hammer assembly 3, and the two ends of the bearing frame 5 are respectively fixed to the main plate 2 by screws.

[0029] like Figure 3 and Figure 5 As shown, the automatic upper plate 1 and the bearing frame 5 are laid flat on the main plate 2. The bearing frame 5 includes a second protrusion 51 in the middle and a long arm arranged on the side of the second protrusion 51. The second protrusion 51 is sleeved on the automatic hammer assembly 3, and the long arm is fixed to the main plate 2 by screws.

[0030] If the plane space allows, the number of long arms can be 2-4. Figure 3 In the embodiment, the number of long arms is two, and the two long arms of the bearing frame 5 are fixed to the main plate 2 with two screws. In addition, the second protrusion 51 is arranged on the fixing seat, and the side of the fixing seat is fixed with the long arm, and the shape of the fixing seat can be various shapes that can realize the function of the present invention, such as fan-shaped, semicircular, circular, polygonal, etc. This structure is different from Figure 2 The conventional automatic hammer assembly 3 and hammer wheel assembly 4 are also fixed to the first protrusion 11 in the automatic upper clamping plate 1, so that the transmission gear train, the automatic hammer assembly 3, and the hammer wheel assembly 4 are fixed to the automatic upper clamping plate 1 at the same time, which increases the thickness of the automatic upper clamping plate 1 and also affects the thickness of the entire axial direction. In this embodiment, the automatic upper clamping plate 1 and the bearing frame 5 are laid flat on the main clamping plate 2, which not only reduces the thickness of the automatic upper clamping plate 1, but also reduces the processing difficulty of the automatic upper clamping plate 1, and facilitates the disassembly and assembly of the automatic hammer assembly 3.

[0031] One end of the transmission assembly is rotatably fixed on the main plate 2, and the other end of the transmission assembly is rotatably fixed on the automatic winding plate 1. The transmission assembly includes a first transmission assembly 6, a reversing assembly 7 and a second transmission assembly 8. The hammer wheel assembly 4, the first transmission assembly 6 and the reversing assembly 7 are meshed, and the reversing assembly 7 is meshed with the second transmission assembly 8. The torsional force of the automatic hammer assembly 3 can be transmitted to the winding ratchet 10 through the transmission components, thereby winding the mainspring 9.

[0032] The number of the first transmission components 6 is determined according to the size and precision of the watch. The more the number of the first transmission components 6 is, the larger the space occupied is and the lower the precision of the watch is. Usually, the number of the first transmission components 6 is 1-3 groups. Figure 2 and Figure 3 In the embodiment, the number of the first transmission assembly 6 is 2 groups, namely the first wheel component 61 and the second wheel component 62. The first wheel component 61 includes a first wheel piece 611 and a first gear shaft 612 riveted together, and the second wheel component 62 includes a second wheel piece 621 and a second gear shaft 622 riveted together. The first wheel piece 611 is meshed with the hammer wheel assembly 4, the first gear shaft 612 is meshed with the second wheel piece 621, and the second gear shaft 622 is meshed with the reversing assembly 7. Figure 3 As shown, the bottom end of the first transmission assembly 6 is rotatably fixed on the main plate 2, and the top end of the second transmission assembly 8 is a free end. In other embodiments, a boss for fixing the second transmission assembly 8 is provided on the automatic upper plate 1, and the top end of the second transmission assembly 8 is rotatably fixed on the boss.

[0033] The number of the reversing components 7 is one or two. Figure 3 In the embodiment, there is one reversing assembly 7 , which includes a reversing wheel piece 71 and a reversing gear shaft 72 riveted together. The reversing wheel piece 71 is meshed with the second gear shaft 62 , and the reversing gear shaft 72 is meshed with the second transmission assembly 8 .

[0034] The number of the second transmission components 8 is 1-4 groups. Figure 3 In the embodiment, the number of the second transmission assembly 8 is 3 groups, namely the third wheel component 81, the fourth wheel component 82 and the fifth wheel component 83. The third wheel component 81 includes a third wheel plate 811 and a third gear shaft 812 riveted together, the fourth wheel component 82 includes a fourth wheel plate 821 and a fourth gear shaft 822 riveted together, and the fifth wheel component 83 includes a fifth wheel plate 831 and a fifth gear shaft 832 riveted together. The third wheel plate 811 is meshed with the reversing gear shaft 72, the third gear shaft 812 is meshed with the fourth wheel plate 821, the fourth gear shaft 822 is meshed with the fifth wheel plate 831, and the fifth gear shaft 832 of the fifth wheel component 83 is meshed with the winding ratchet 10.

[0035] The winding ratchet 10, the mainspring 9 and the barrel arbour 11 are fixed together by a ratchet screw.

[0036] The working process of the automatic winding mechanism of the watch of the present invention is described below by taking the structure of the embodiment as an example:

[0037] like Figure 3-Figure 4 As shown, when the automatic hammer assembly 3 rotates, the hammer wheel assembly 4 drives the first wheel 611 to rotate, and the first wheel 611 and the first gear shaft 612 are fixed together, so that the first gear shaft 612 also rotates; the first gear shaft 612 is meshed with the second wheel 621, and the first gear shaft 612 drives the second wheel 621 to rotate, and the second wheel 621 is fixed together with the second gear shaft 622, and the second gear shaft 622 also rotates; the second gear shaft 622 is meshed with the reversing wheel 71, and the second gear shaft 622 drives the reversing wheel 71 to rotate, and the reversing wheel 71 and the reversing gear shaft 72 are fixed together, and the reversing gear shaft 72 also rotates; the reversing gear shaft 72 is meshed with the third gear shaft 621, and the second gear shaft 622 drives the reversing wheel 71 to rotate, and the reversing wheel 71 and the reversing gear shaft 72 are fixed together, and the reversing gear shaft 72 also rotates; The wheel 811 is meshed, and the reversing gear shaft 72 drives the third wheel 811 to rotate. The third wheel 811 and the third gear shaft 812 are fixed together, and the third gear shaft 812 also rotates; the third gear shaft 812 is meshed with the fourth wheel 821, and the third gear shaft 812 drives the fourth wheel 821 to rotate. The fourth wheel 821 and the fourth gear shaft 822 are fixed together, and the fourth gear shaft 822 also rotates; the fourth gear shaft 822 drives the fifth wheel 831 to rotate, and the fifth wheel 831 drives the winding ratchet 10 to rotate. The winding ratchet 10 and the mainspring 9 are fixed together by the barrel shaft 11 and the winding ratchet 10 screws, and the barrel shaft 11 rotates to wind the mainspring 9. The automatic hammer assembly 3 and the hammer wheel assembly 4 are fixed to the main plate 2 through the bearing frame 5, as shown in FIG. Figure 3 and Figure 5 As shown, the automatic upper plate 1 and the bearing frame 5 are laid flat on the main plate 2. The bearing frame 5 includes a second protrusion 51 in the middle and a long arm arranged on the side of the second protrusion 51. The second protrusion 51 is sleeved on the automatic hammer assembly 3, and the long arm is fixed to the main plate 2 by screws.

[0038] If the plane space allows, the number of long arms can be 2-4. Figure 3 In the embodiment, the number of the long arms is two, and the two long arms of the bearing frame 5 are fixed to the main plate 2 with two screws. Figure 2The conventional automatic hammer assembly 3 and hammer wheel assembly 4 shown are fixed to the first protrusion 11 in the automatic upper clamping plate 1, so that the transmission wheel train and the automatic hammer assembly 3 and the hammer wheel assembly 4 are fixed to the automatic upper clamping plate 1 at the same time, which increases the thickness of the automatic upper clamping plate 2 and also affects the thickness of the entire axial direction. In this embodiment, the automatic upper clamping plate 1 and the bearing frame 5 are laid flat on the main clamping plate 2, which not only reduces the thickness of the automatic upper clamping plate 1, but also reduces the processing difficulty of the automatic upper clamping plate 1, and facilitates the disassembly and assembly of the automatic hammer assembly 3. The first wheel component 61, the second wheel component 62, the reversing component 7, the third wheel component 81, the fourth wheel component 82, and the fifth wheel component 83 are fixed between the main clamping plate 2 and the automatic upper clamping plate 1 of the movement, which is different from the conventional automatic part wheel train fixed between the automatic upper clamping plate 1 and the automatic lower clamping plate 12, which greatly reduces the thickness of the entire automatic structure, thereby reducing the entire thickness of the movement, and also reduces the size matching of one level, and improves the precision of the automatic part.

[0039] The present invention also provides a mechanical watch, including a watch case, wherein the automatic winding mechanism of the mechanical watch is arranged in the watch case. The automatic hammer structure is fixed to the main plate 2 through the bearing frame 5, which effectively reduces the thickness of the automatic winding mechanism, thereby greatly reducing the thickness of the mechanical watch.

[0040] The mechanical watch is connected to the automatic hammer bearing through the bearing frame 5, and the protruding structure on the automatic upper clamping plate 1 originally connected to the automatic hammer is eliminated. The automatic upper clamping plate 1 and the bearing frame 5 are respectively laid flat on the main clamping plate 2, which reduces the thickness of the automatic upper clamping plate 1, and leaves space for the transmission structure to be directly installed on the main clamping plate 2. At the same time, the automatic hammer part is sunk, and then the entire automatic transmission structure can be sunk, so as to achieve the purpose of thinning. The transmission part of the mechanical watch is directly installed between the main clamping plate 2 and the automatic upper clamping plate 1, which can effectively reduce the thickness of the automatic structure, thereby further reducing the thickness of the watch movement; because there is no one-level connection structure in the middle, an error factor is reduced, and the installation accuracy of the transmission part is improved.

[0041] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
