Description
Technical Field
[0001] The present invention relates to the field of mechanical watches, and particularly to an automatic time-reporting watch with an anti-jamming function. Background Art
[0002] With the development of society and the improvement of consumer 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] The time-reporting structure described in the patent with the publication number CN217425939U and the name "Automatic Time-Reporting Structure of a Watch" has a principle that the timekeeping mainspring drives the timekeeping system to operate. The operation of the timekeeping system can trigger a set of lever structures to control the clutch state of the driving wheel, and ultimately control the release of energy of the time-reporting mainspring, so that the entire mechanism reports time. There is a problem in its operation, that is, when only the timekeeping mainspring has a spring and the time-reporting mainspring has no spring, the timekeeping system can still control the driving wheel to disengage through this set of lever structures. At this time, the starting plate together with the positioning head drops, but due to the lack of spring of the time-reporting mainspring, the driving wheel cannot drive the starting plate together with the positioning head to rise and return to the original position. Therefore, during the continuous running of the watch, especially during the process from 12 o'clock to 1 o'clock, the time-reporting cam will collide with the positioning head, resulting in the possibility that the time-reporting cam jams the positioning head and causes the watch to stop.
[0004] If the situation of the watch stopping frequently occurs, it will affect the user experience of the watch user. Therefore, it is urgently necessary to design an anti-jamming structure for an automatic time-reporting watch to solve these problems once and for all. Summary of the Invention
[0005] The present invention provides an automatic time-reporting watch with an anti-jamming function, which has the effect of preventing the positioning cam and the positioning head from jamming each other when the positioning cam accidentally collides with the positioning head. The specific technical solutions are as follows:
[0006] An automatic time-reporting watch with an anti-jamming function, 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 the first end corresponds to the positioning cam. The starting plate can drop and the first end of the active positioning head can hit the positioning cam to achieve positioning. When the time-reporting mainspring has no spring, the rotation of the positioning cam can drive the active positioning head to move to avoid the positioning cam, thereby preventing the positioning cam and the active positioning head from jamming.
[0007] 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.
[0008] 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.
[0009] Furthermore, the positioning cam is provided with a plurality of steps with increasing depths, and two adjacent steps on the positioning cam are connected by an inclined plane.
[0010] Furthermore, the movable positioning head includes a second end portion, and the second end portion of the movable positioning head corresponds to the stop-reporting wheel assembly, and the stop-reporting wheel assembly is connected to the stop-reporting button, and 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 start plate can drive the timing mechanism to tell the time; when the stop-reporting wheel assembly is in the stop-reporting position, the stop-reporting wheel assembly is engaged with the second end portion of the movable positioning head to realize the stop-reporting function.
[0011] 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.
[0012] Furthermore, the stop alarm conversion cam and the stop alarm conversion wheel are an integrally formed structure.
[0013] 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.
[0014] 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.
[0015] Furthermore, the second end of the movable positioning head is hook-shaped, and the outer side of the hook is an arc inclined surface.
[0016] The automatic time-reporting watch with anti-jamming function of the present invention is ingeniously designed, has good workmanship and simple assembly, and is suitable for large-scale production. Since a rotatable movable positioning head is provided on the starting plate, during the time-reporting process, when the time-reporting spring has no string, the starting plate cannot return to its position, and the positioning cam will hit the first end of the movable positioning head. Then, as the positioning cam rotates, the movable positioning head will move under the impact of the positioning cam and avoid the positioning cam, thus preventing the watch from jamming and stopping.
[0017] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are given below.

[0026] In order to better understand the purpose, function and specific design of the present invention, the automatic time-reporting watch with anti-jamming function of the present invention will be further described in detail below with reference to the drawings.
[0027] Based on the structure of the patent "Automatic Time Reporting Structure of a Watch" with the publication number CN217425939U, as Figures 1-5 shown, the automatic time reporting watch with an anti-jamming function 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 provided on the starting plate 100. The active positioning head 101 includes a first end D and a second end C. The first end D of the active positioning head 101 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 time reporting stop wheel assembly. The time reporting stop wheel assembly is connected to the time reporting stop button 630. The time reporting stop button 630 can drive the time reporting stop wheel assembly to rotate, so that the time reporting stop wheel assembly is in the release position or the time reporting stop position. When the time reporting stop wheel assembly is in the release position, the starting plate 100 can drive the time reporting mechanism to report time. When the time reporting stop wheel assembly is in the time reporting stop position, the time reporting stop 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, so as to realize the time reporting stop function.
[0028] It can be understood that the positioning cam 110 is equivalent to the time reporting cam in the patent "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 being provided with 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.
[0029] Specifically, as Figures 1-3 shown, the time reporting stop wheel assembly includes a time reporting stop conversion cam 710 and a time reporting stop conversion wheel 720. The time reporting stop conversion cam 710 and the time reporting stop conversion wheel 720 are coaxially and fixedly connected. Preferably, the time reporting stop conversion cam 710 and the time reporting stop conversion wheel 720 are of an integrally formed structure. The time reporting stop conversion cam 710 can be engaged with the second end C of the active positioning head 101. The time reporting stop conversion wheel 720 corresponds to the time reporting stop button 630. Pressing the time reporting stop button 630 can drive the time reporting stop conversion wheel 720 to rotate, thereby driving the time reporting stop conversion cam 710 to rotate, so that the time reporting stop conversion cam 710 is in the release position or the time reporting stop position.
[0030] 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.
[0031] The stop alarm conversion cam 71O 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 an 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 .
[0032] 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.
[0033] 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.
[0034] 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-shaped 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.
[0035] 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-shaped 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 prevent subsequent time-reporting. By providing an arc-shaped inclined surface at the second end C of the movable positioning head 1O 1, it can prevent the second end C of the movable positioning head 101 and the stop-alarm teeth of the stop-alarm conversion cam 710 from getting stuck with each other when they collide.
[0036] In addition, as Figure 2 and Figure 4As shown, when the stop-alarm conversion cam 710 is in the release position, the stop-alarm conversion cam 710 does not jam the second end C of the movable positioning head 101. The starting plate 100 can fall, and the first end D of the movable positioning head 101 can strike the positioning cam 110. During normal timekeeping, the starting plate 100 will return to the position where its side wall is close to the eccentric pin 291 with the timekeeping. However, when the timekeeping spring is not wound, the starting plate 100 cannot return to its position. If the watch runs normally or is adjusted manually, the positioning cam 110 will strike the first end D of the movable positioning head 101. Then, as the positioning cam 110 rotates, since the movable positioning head 101 is movably arranged on the starting plate 100, the rotation of the positioning cam 110 can drive the movable positioning head to move, that is, the movable positioning head 101 will move under the impact of the positioning cam 110 and avoid the positioning cam 110, thus preventing the positioning cam 110 and the movable positioning head 101 from jamming each other, and no situation of jamming and stopping the watch will occur. Since the movable positioning head 101 is connected to the positioning head return spring 610, after the movable positioning head 101 is knocked open, it will continuously receive the restoring force provided by the positioning head return spring 610. When the timekeeping spring of the watch is wound again, as the starting plate 100 rises, the movable positioning head 101 returns to its original position under the action of the positioning head return spring 610. Its original position is limited by the positioning head limit pin 101a.
[0037] Preferably, as Figures 6-7 shown, in order to prevent the positioning cam 110 from jamming the movable positioning head 101 when the pointer is turned back, the adjacent two steps on the positioning cam 110 of this embodiment are connected by an inclined surface. When the pointer is turned back, the inclined surface of the positioning cam 110 can make the movable positioning head 101 climb on its respective steps, and finally achieve the effect of preventing jamming.
[0038] The automatic timekeeping watch with the anti-jamming function of the present invention is ingeniously designed, has good workmanship and simple assembly, and is suitable for large-scale production. Since a rotatable movable positioning head is arranged on the starting plate, during the timekeeping process, when the timekeeping spring is not wound, the starting plate cannot return to its position, the positioning cam will strike the first end of the movable positioning head, and then as the positioning cam rotates, the movable positioning head will move under the impact of the positioning cam and avoid the positioning cam, thus avoiding the situation of jamming and stopping the watch.
[0039] 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 them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
