Description

Technical Field

[0001] The present invention relates to the field of mechanical watches, and particularly to a stop-reporting structure for an automatic time-reporting watch. Background Art

[0002] With the development of society and the improvement of consumers' demands, watches that can automatically report time have emerged as the times require. However, the existing mechanical watches that can automatically report time have complex structures, numerous functions, high prices, complex manufacturing processes, and high assembly difficulties.

[0003] Although the structure described in the patent with the publication number CN217425939U and the name "Automatic Time-Reporting Structure of a Watch" is simple and has a low assembly difficulty, it does not have a button stop-reporting structure. In some scenarios, such as meetings, libraries, etc., the inability to stop reporting will greatly reduce the user experience. Although the safety lever can achieve the stop-reporting effect after pulling out the stem, this state cannot be maintained for a long time and can only be activated during time adjustment. This is because after pulling out the stem, the running of the watch will drive the front valve mechanism to operate, which will have a very bad impact on the running of the watch and can even cause the watch to stop in severe cases. Therefore, the safety lever can only be used for insurance and not for stop reporting. Adding a button stop-reporting structure can greatly improve the user experience of watch users.

[0004] Therefore, there is an urgent need to design a mechanical watch that can automatically report time and has a stop-reporting structure. Summary of the Invention

[0005] The present invention provides a stop-reporting structure for an automatic time-reporting watch, which has the effect of realizing the stop-reporting function of the automatic time-reporting watch by pressing a stop-reporting button. The specific technical solutions are as follows:

[0006] A stop-reporting structure for an automatic time-reporting watch, which includes a starting plate. The movement of the starting plate can drive the time-reporting mechanism to report time. An active positioning head is movably arranged on the starting plate. The active positioning head includes a first end and a second end. The first end corresponds to a positioning cam, and the second end of the active positioning head corresponds to a stop-reporting wheel assembly. The stop-reporting wheel assembly is connected to a stop-reporting button. The stop-reporting button can drive the stop-reporting wheel assembly to rotate so that the stop-reporting wheel assembly is in a release position or a stop-reporting position. When the stop-reporting wheel assembly is in the release position, the starting plate can drive the time-reporting mechanism to report time. When the stop-reporting wheel assembly is in the stop-reporting position, the stop-reporting wheel assembly is engaged with the second end of the active positioning head to achieve the stop-reporting function.

[0007] Furthermore, the stop alarm wheel assembly includes a stop alarm conversion cam and a stop alarm conversion wheel. The stop alarm conversion cam is coaxially fixedly connected to the stop alarm conversion wheel. The stop alarm conversion cam can be clamped with the second end of the movable positioning head. The stop alarm conversion wheel corresponds to the stop alarm button. Pressing the stop alarm button can drive the stop alarm conversion wheel to rotate, thereby driving the stop alarm conversion cam to rotate, so that the stop alarm conversion cam is in the release position or the stop alarm position.

[0008] Furthermore, the stop alarm conversion cam and the stop alarm conversion wheel are an integrally formed structure.

[0009] Furthermore, a plurality of toggle teeth are provided on the stop-alarm conversion wheel, and pressing the stop-alarm button can conflict with the toggle teeth, thereby driving the stop-alarm conversion wheel to rotate; the stop-alarm conversion wheel is connected to the stop-alarm spring, and the stop-alarm spring can limit the stop-alarm conversion wheel to prevent the stop-alarm conversion wheel from rotating.

[0010] Furthermore, a plurality of stop teeth are provided on the stop conversion cam, and the stop teeth can be engaged with the second end of the movable positioning head to realize the stop function.

[0011] Furthermore, the second end of the movable positioning head is hook-shaped, and the outer side of the hook is an arc inclined surface.

[0012] Furthermore, the movable positioning head is hinged on the starting plate, a positioning head limiting hole is arranged on the movable positioning head, a positioning head limiting pin is arranged on the starting plate, the diameter of the positioning head limiting pin is smaller than the diameter of the positioning head limiting hole, the positioning head limiting pin is accommodated in the positioning head limiting hole, and the positioning head limiting pin can limit the moving range of the movable positioning head.

[0013] Furthermore, the movable positioning head is connected to a positioning head return spring. After the movable positioning head is moved by an external force, the positioning head return spring can provide a restoring force for the movable positioning head.

[0014] Furthermore, the stop alarm button is hinged on the movement, and the stop alarm button is connected to a button reset spring. After the stop alarm button is pressed, the button reset spring can reset the stop alarm button.

[0015] Furthermore, a button limiting hole is provided on the stop alarm button, and a button limiting pin is provided on the machine core. The diameter of the button limiting hole is larger than the diameter of the button limiting pin, and the button limiting pin can limit the pressing range of the stop alarm button.

[0016] The stop structure of the automatic timekeeping watch of the present invention is ingeniously designed, has good processability, is simple to assemble, and is suitable for mass production. By arranging a rotatable movable positioning head on the starting plate, the movable positioning head can be engaged with the stop conversion cam to realize the stop function, and by the cooperation of the toggle teeth on the stop conversion wheel and the stop spring, each time the stop button is pressed, the stop conversion wheel can only rotate by the distance of one toggle tooth, so that each time the stop button is pressed, the stop conversion cam can be switched between the release position and the stop position.

[0017] The above description is only an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the content of the specification.

[0024] In order to better understand the purpose, function and specific design of the present invention, the stop reporting structure of the automatic time reporting watch of the present invention will be further described in detail below with reference to the drawings.

[0025] On the basis of the structure of the patent "Automatic Time Reporting Structure of a Watch" with the publication number CN217425939U, as Figures 1-5As shown in the figure, the stop reporting structure of the automatic time reporting watch of the present invention includes a starting plate 100. The movement of the starting plate 100 can drive the time reporting mechanism to report time. An active positioning head 101 is arranged on the starting plate 100. The active positioning head 101 includes a first end D and a second end C. The first end D corresponds to the positioning cam 110. The first end D of the active positioning head 101 can be blocked by the positioning cam 110, thereby restricting the movement distance of the starting plate 100, completing the positioning of the starting plate 100, and thus realizing the time reporting corresponding to the time. The second end C of the active positioning head 101 corresponds to the stop reporting wheel assembly. The stop reporting wheel assembly is connected to the stop reporting button 630. The stop reporting button 630 can drive the stop reporting wheel assembly to rotate, so that the stop reporting wheel assembly is in the release position or the stop reporting position. When the stop reporting wheel assembly is in the release position, the starting plate 100 can drive the time reporting mechanism to report time. When the stop reporting wheel assembly is in the stop reporting position, the stop reporting wheel assembly is engaged with the second end C of the active positioning head 101, and the starting plate 100 cannot move, so that the time reporting mechanism cannot be driven to report time, thereby realizing the stop reporting function.

[0026] It can be understood that the positioning cam 110 is equivalent to the time reporting cam in the patent of "Automatic Time Reporting Structure of a Watch" with the publication number CN217425939U. There are 12 steps with increasing depths on the time reporting cam. The 12 steps correspond to 12 hours, and the time reporting corresponding to 12 hours is achieved by contacting steps with different depths. However, the positioning cam 110 in the present application is not limited to having 12 steps with increasing depths. The positioning cam 110 in the present application is provided with multiple steps with increasing depths, and the time reporting corresponding to the corresponding function can be achieved by contacting steps with different depths.

[0027] Specifically, as Figures 1-3 shown, the stop reporting wheel assembly includes a stop reporting conversion cam 710 and a stop reporting conversion wheel 720. The stop reporting conversion cam 710 and the stop reporting conversion wheel 720 are coaxially and fixedly connected. Preferably, the stop reporting conversion cam 710 and the stop reporting conversion wheel 720 are an integrally formed structure. The stop reporting conversion cam 710 can be engaged with the second end C of the active positioning head 101. The stop reporting conversion wheel 720 corresponds to the stop reporting button 630. Pressing the stop reporting button 630 can drive the stop reporting conversion wheel 720 to rotate, thereby driving the stop reporting conversion cam 710 to rotate, so that the stop reporting conversion cam 710 is in the release position or the stop reporting position.

[0028] The stop alarm conversion wheel 720 of this embodiment is provided with a plurality of toggle teeth, and pressing the stop alarm button 630 can conflict with the toggle teeth, thereby driving the stop alarm conversion wheel 720 to rotate. The stop alarm conversion wheel 720 is connected to the stop alarm spring 600, and the stop alarm spring 600 can limit the stop alarm conversion wheel 720 to prevent the stop alarm conversion wheel 720 from rotating; the stop alarm spring 600 is provided with a triangular limiting portion, and the triangular limiting portion can be engaged with the toggle teeth to achieve the limit of the stop alarm conversion wheel 720, and at the same time, each time the stop alarm button 630 is pressed, the stop alarm conversion wheel 720 only rotates a distance of a toggle tooth, so that each time the stop alarm button 630 is pressed, the stop alarm conversion cam 710 can be switched between the release position and the stop alarm position.

[0029] The stop alarm conversion cam 710 is provided with a plurality of stop alarm teeth, which can be engaged with the second end C of the movable positioning head 101 to realize the stop alarm function. The movable positioning head 101 is movably arranged on the starting plate 100, and the second end C of the movable positioning head 101 is hook-shaped, and the outer side of the hook is a circular arc slope. The movable positioning head 101 of this embodiment is hinged on the starting plate 100, and a positioning head limiting hole is provided on the movable positioning head 101, and a positioning head limiting pin 101a is provided on the starting plate 100. The diameter of the positioning head limiting pin 101a is smaller than the diameter of the positioning head limiting hole, and the positioning head limiting pin 101a is accommodated in the positioning head limiting hole, and the positioning head limiting pin 101a can limit the moving range of the movable positioning head 101. It can be understood that a positioning head limiting groove can also be provided on the movable positioning head 101, and the moving range of the movable positioning head 101 is limited by the positioning head limiting groove. Preferably, the movable positioning head 101 is connected to the positioning head return spring 610 , and after the movable positioning head 101 is moved by an external force, the positioning head return spring 610 can provide a restoring force for the movable positioning head 101 .

[0030] The stop alarm button 630 of this embodiment is hinged on the machine core, and the stop alarm button 630 is connected to the button reset spring 620. After pressing the stop alarm button 630, the button reset spring 620 can reset the stop alarm button 630; a button limiting hole is provided on the stop alarm button 630, and a button limiting pin 630a is provided on the machine core. The diameter of the button limiting hole is larger than the diameter of the button limiting pin 630a, and the button limiting pin 630a can limit the pressing range of the stop alarm button 630.

[0031] like Figure 2As shown, when the stop-alarm conversion cam 710 is in the release position, the starting spring 210 can drive the starting plate 100 to start. After that, the second end C of the movable positioning head 101 will move along the dotted line and will not get stuck on the stop-alarm teeth of the stop-alarm conversion cam 710. The first end D of the movable positioning head 101 can finally hit the positioning cam 110. The subsequent time-reporting working process is the same as that described in the patent "Automatic Time-Reporting Structure of a Watch" with the publication number CN217425939U, and will not be elaborated here.

[0032] As Figure 3 shown, when the stop-alarm is turned on before the starting plate 100 drops, the stop-alarm button 630 toggles the stop-alarm conversion wheel 720 to rotate counterclockwise, and the stop-alarm conversion wheel 720 drives the stop-alarm conversion cam 710 to rotate synchronously; since the contact surface between the stop-alarm conversion cam 710 and the second end C of the movable positioning head 101 is an arc inclined surface, during the counterclockwise rotation of the stop-alarm conversion cam 710, it will push and lift the second end C of the movable positioning head 101, and the movable positioning head 101 will be lifted counterclockwise by a small distance. When the stop-alarm conversion wheel 720 moves to Figure 1 the position, the stop-alarm teeth catch the second end C of the movable positioning head 101 to complete the stop-alarm function.

[0033] As Figure 5 shown, when the stop-alarm is turned on after the starting plate 100 drops, the stop-alarm button 630 toggles the stop-alarm conversion wheel 720 to rotate counterclockwise, and the stop-alarm conversion wheel 720 drives the stop-alarm conversion cam 710 to rotate to the stop-alarm position; as the starting plate 100 rises, the second end C of the movable positioning head 101 abuts against the stop-alarm teeth of the stop-alarm conversion cam 710. Since the contact surface between the stop-alarm conversion cam 710 and the second end C of the movable positioning head 101 is an arc inclined surface, during the rising process of the starting plate 100, the second end C of the movable positioning head 101 will be pushed and lifted by the stop-alarm teeth of the stop-alarm conversion cam 710, and the movable positioning head 101 will be lifted counterclockwise by a small distance. When the starting plate 100 and the movable positioning head 101 move to Figure 1 the position, the stop-alarm teeth catch the second end C of the movable positioning head 101 to complete the stop-alarm function to avoid subsequent time-reporting.

[0034] In addition, as Figure 2 and Figure 4As shown, when the stop-time conversion cam 710 is in the release position, the stop-time conversion cam 710 does not catch the second end C of the movable positioning head 101, and the start plate 100 can fall and make the first end D of the movable positioning head 101 hit the positioning cam 110. In the normal time-telling process, the start plate 100 will return to the position where its side wall is close to the eccentric nail 291 as the time is told, but when the time-telling spring has no string, the start plate 100 cannot return to its position. If the watch is running normally or manually adjusted, the positioning cam 110 will hit the first end D of the movable positioning head 101, and then as the positioning cam 110 rotates, since the movable positioning head 101 is movably arranged on the start plate 100, the movable positioning head 101 will move under the impact of the positioning cam 110 and avoid the positioning cam 110, so that the stop watch will not be stuck. Since the movable positioning head 101 is connected to the positioning head return spring 610, the movable positioning head 101 will continue to be subject to the restoring force provided by the positioning head return spring 610 after being hit open. When the time signal spring of the watch is wound up again, as the starting plate 100 is lifted, the movable positioning head 101 is restored to its original position by the positioning head return spring 610. Its original position is limited by the positioning head limiting nail 101a.

[0035] The automatic timekeeping mechanism of the watch of the present invention is ingeniously designed, has good processability, is simple to assemble and is suitable for mass production. By arranging a rotatable movable positioning head 101 on the starting plate 100, the movable positioning head 101 can be engaged with the stop-time conversion cam 710 to realize the stop-time function, and by the cooperation of the toggle teeth on the stop-time conversion wheel 720 and the stop-time spring 600, each time the stop-time button 630 is pressed, the stop-time conversion wheel 720 is rotated only by the distance of one toggle tooth, so that each time the stop-time button 630 is pressed, the stop-time conversion cam 710 can be switched between the release position and the stop-time position.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
