Description

Technical Field

[0001] This application relates to the field of timing instrument technology, and in particular to a dial fork display mechanism and a dial fork display watch. Background Technology

[0002] Currently, watches are no longer simply timekeeping tools; they are increasingly seen as accessories. Traditional watches are analog watches, where the hands move while the dial remains stationary, and consumers read the time by observing the position of the hands on the dial.

[0003] As consumers continue to improve their quality of life, they are no longer satisfied with the conventional way watches indicate information. Therefore, there is a need for a new type of watch to solve the problem of poor display quality in existing analog watches. Summary of the Invention

[0004] In view of this, embodiments of this application provide a dial fork display mechanism and a dial fork display watch to solve the problem of poor display effect of existing analog watches.

[0005] The first aspect of this application discloses a shift fork display mechanism, including a base plate, a time dial, a transmission system, and at least two sets of shift fork assemblies. The time dial is rotatably connected to the base plate, and a plurality of transmission columns are arranged at intervals along its circumference on the time dial. The shift fork assembly includes a rotating member, a shift fork, and a positioning column. The rotating member is rotatably connected to the base plate. The transmission system is used to connect to the output shaft of the base movement to drive the rotating member to rotate. The shift fork is rotatably connected to the rotating member. The shift fork has a sliding groove, and the sliding groove of each shift fork alternately allows the corresponding transmission column to enter. The positioning column is fixedly or rotatably connected to the base plate and is located within the sliding groove.

[0006] The shift fork display mechanism provided in this embodiment includes a base plate, a dial, a transmission system, and at least two sets of shift fork assemblies. The base plate serves as the mounting base for the dial, transmission system, and shift fork assemblies. Each shift fork assembly includes a rotating component, a shift fork, and a positioning post. The rotating component is driven to rotate by the transmission system connected to the output shaft of the base movement. During rotation, the rotating component drives the shift fork to rotate. Under the positioning action of the positioning post, the groove on the shift fork moves closer to and further away from the transmission post on the dial. When the transmission post enters the groove, the shift fork rotates with the rotating component, driving the dial to rotate by a certain angle. Furthermore, since at least two sets of shift fork assemblies are arranged, the alternating action of the shift fork assemblies ensures that the dial continues to rotate, achieving hour display. The aforementioned shift fork display mechanism utilizes the cooperation between the shift fork assembly and the transmission post on the dial to achieve dial rotation, increasing the watch's aesthetic appeal and visual interest, and enhancing its display effect.

[0007] In some embodiments, the shift fork assembly is provided in two sets, and the two sets of the shift fork assembly are located on both sides of the center of the base clamping plate.

[0008] By adopting the above technical solution, the structure of the shift fork display mechanism is simplified while ensuring the normal rotation of the time dial.

[0009] In some embodiments, the transmission system includes a driving gear and two sets of driven gears. The driving gear is connected to the output shaft, and the two sets of driven gears are respectively arranged corresponding to two rotating members. Each driven gear set includes a first driven gear and a second driven gear arranged coaxially. The diameter of the first driven gear is greater than or less than the diameter of the second driven gear. The driving gear is connected to the two first driven gears, and the two second driven gears are respectively connected to the two rotating members.

[0010] Since the first driven gear and the second driven gear are arranged coaxially, and the diameter of the first driven gear is greater than or less than the diameter of the second driven gear, the overall structure of the driving gear, intermediate gear, driven gear set and rotating parts can be made more compact.

[0011] In some embodiments, the rotating element is a rotating gear, and the end of the shift fork is eccentrically rotatably connected to the rotating gear.

[0012] Because the rotating gear has good stability during rotation, it ensures the stability of the shift fork rotation, thereby avoiding jamming when the shift fork's groove mates with the transmission column.

[0013] In some embodiments, the shift fork display mechanism further includes a dividing disc, which is used to fix the output shaft or the drive gear, and the rotation speed of the dividing disc is twice the rotation speed of the rotating member.

[0014] Since the dial is fixed on the output shaft, the dial and the hour dial are located on opposite sides of the center of the base plate, which improves the aesthetics of the shift fork display mechanism.

[0015] In some embodiments, twelve drive columns are arranged at circumferential intervals along the clock face.

[0016] By adopting the above technical solution, the number of transmission columns corresponds to the number of hours on the dial, thus ensuring that the engagement process between each shift fork assembly and the transmission column is exactly one hour.

[0017] In some embodiments, a limiting portion is provided at the end of the positioning post away from the base clamp to prevent the shift fork from moving axially along the positioning post.

[0018] By adopting the above technical solution, the axial movement of the shift fork along the positioning post can be restricted, thus ensuring the stability of the shift fork.

[0019] In some embodiments, the groove opening is a flared opening.

[0020] By adopting the above technical solution, it is beneficial for the transmission column on the dial to enter and exit the slide groove on the shift fork.

[0021] In some embodiments, the base plate is provided with an hour arrow indicating the hour markers on the dial.

[0022] By adopting the above technical solution, the hour markers on the dial can be accurately indicated, ensuring the accuracy of time reading on the dial.

[0023] The second aspect of this application discloses a fork-display watch that includes the fork-display mechanism described in the first aspect.

[0024] The watch with the fork display described above adopts all embodiments of the fork display mechanism described above, and therefore has at least all the beneficial effects of the above embodiments, which will not be described in detail here. Attached Figure Description

[0040] Currently, watches are no longer simply timekeeping tools; they are increasingly seen as accessories. Traditional watches are analog watches, where the hands move while the dial remains stationary, and consumers read the time by observing the position of the hands on the dial.

[0041] As consumers continue to improve their quality of life, they are no longer satisfied with the conventional way watches indicate information. Therefore, there is a need for a new type of watch to solve the problem of poor display quality in existing analog watches.

[0042] To address the poor display quality of analog watches, the inventors conducted in-depth research and designed a dial fork display mechanism and a dial fork display watch.

[0043] The rotating component of this fork display mechanism is driven to rotate by a transmission system connected to the output shaft of the base movement. During rotation, the rotating component drives the fork to rotate, and the positioning post positions the fork, causing the groove on the fork to move closer to and further away from the transmission post on the hour dial, thus driving the hour dial to rotate at a certain angle. Furthermore, since there are at least two sets of fork assemblies, the alternating action of the fork assemblies ensures that the hour dial continues to rotate, achieving the display of hours. This fork display mechanism utilizes the cooperation between the fork assemblies and the transmission post on the hour dial to achieve the rotation of the hour dial, increasing the watch's aesthetic appeal and visual interest, and enhancing its display effect.

[0044] An embodiment of the first aspect of this application provides a toggle fork display mechanism 100. Please also refer to... Figure 1 and Figure 4 The shift fork display mechanism 100 includes a base plate 10, a clock face 20, a transmission system 40, and at least two sets of shift fork assemblies 30. The clock face 20 is rotatably connected to the base plate 10, and multiple transmission columns 21 are arranged at intervals along its circumference on the clock face 20. The shift fork assembly 30 includes a rotating member 33, a shift fork 32, and a positioning column 31. The rotating member 33 is rotatably connected to the base plate 10. The transmission system 40 is used to connect with the output shaft of the base mechanism to drive the rotating member 33 to rotate. The shift fork 32 is rotatably connected to the rotating member 33. The shift fork 32 has a sliding groove 321. The sliding groove 321 of each shift fork 32 is alternately used for the corresponding transmission column 21 to enter. The positioning column 31 is fixedly or rotatably connected to the base plate 10 and is located in the sliding groove 321.

[0045] One side of the base plate 10 is used to mount the dial 20, the shift fork assembly 30, and the transmission system 40, while the other side of the base plate 10 is the base movement. The base plate 10 is provided with clearance holes for the output shaft of the base movement. The shape of the base plate 10 is not limited; for example, the shape of the base plate 10 can be circular, rectangular, etc.

[0046] The hour dial 20 is a circular dial, such as Figure 4 As shown, the hour dial 20 is fixed to the first rotating shaft 13 by screws, meaning the hour dial 20 is rotatably connected to the base clamping plate 10 via the first rotating shaft 13. The hour dial 20 is provided with hour markers 22. In other embodiments, the hour dial 20 can be welded or interference-fitted to the first rotating shaft 13.

[0047] The transmission column 21 is cylindrical in shape and is located between two adjacent hour markers 22. In other embodiments, the transmission column 21 includes two segments, one of which is a polygonal segment and the other is a cylindrical segment, which engages with the groove 321 of the shift fork 32.

[0048] Optionally, the drive column 21 can be integrally formed with the clock face 20; the drive column 21 can also be separately fixed to the clock face 20, for example, the drive column 21 can be welded or interference-fitted onto the clock face 20.

[0049] like Figure 3 As shown, the rotating component 33 is fixed to the third rotating shaft 15 by screws, that is, the rotating component 33 is rotatably connected to the base clamping plate 10 through the third rotating shaft 15. In other embodiments, the rotating component 33 may be welded or interference-fitted to the third rotating shaft 15.

[0050] like Figure 4As shown, the fork 32 is provided with a sliding groove 321 and a rotating hole 323. The notch 322 of the sliding groove 321 and the rotating hole 323 are respectively located at both ends of the fork 32. The end of the fork 32 is rotationally connected to the rotating member 33 through the rotating hole 323 and a pin. Among them, the rotation axis of the rotating member 33 is parallel to the rotation axis of the fork 32.

[0051] The sliding grooves 321 of each fork 32 alternately allow the corresponding transmission columns 21 to enter. That is, when the sliding groove 321 of one fork 32 allows a transmission column 21 to enter, the sliding groove 321 of the other fork 32 is away from the transmission column 21. Therefore, the two forks 32 alternately drive the time disk 20 to rotate.

[0052] The positioning column 31 is threadedly connected to the second rotating shaft 14. That is, the positioning column 31 is rotationally connected to the base splint 10 through the second rotating shaft 14 to reduce the friction between the positioning column 31 and the sliding groove 321, which is beneficial to the rotation of the fork 32. In other embodiments, the positioning column 31 can be fixed on the base splint 10. Among them, since the positioning column 31 is located in the sliding groove 321, the fork 32 can rotate around the positioning column 31.

[0053] The fork display mechanism 100 provided in the embodiment of the present application includes a base splint 10, a time disk 20, a transmission system 40 and at least two groups of fork assemblies 30. The base splint 10 serves as the installation base for the time disk 20, the transmission system 40 and the fork assemblies 30; the fork assembly 30 includes a rotating member 33, a fork 32 and a positioning column 31. The rotating member 33 is driven to rotate by the transmission system 40 connected to the output shaft of the base movement. During the rotation of the rotating member 33, the fork 32 is driven to rotate. Under the positioning effect of the positioning column 31 on the fork 32, the sliding groove 321 on the fork 32 approaches and moves away from the transmission column 21 on the time disk 20. When the transmission column 21 enters the sliding groove 321, the fork 32 rotates with the rotating member 33 to drive the time disk 20 to rotate a certain angle. Moreover, since at least two groups of fork assemblies 30 are arranged, the time disk 20 is ensured to keep rotating under the alternating action of the fork assemblies 30 to realize the display of hours. The above-mentioned fork display mechanism 100 uses the cooperation between the fork assembly 30 and the transmission column 21 on the time disk 20 to realize the rotation of the time disk 20, which increases the ornamental value and interest of the watch and improves the display effect of the watch.

[0054] Please also refer to Figure 1 and Figure 2 In some embodiments, two groups of fork assemblies 30 are provided, and the two groups of fork assemblies 30 are located on both sides of the center of the base splint 10.

[0055] The two groups of fork assemblies 30 are symmetrically arranged on both sides of the time disk 20, and the rotation axis of the time disk 20 and the rotation axes of the two rotating members 33 are arranged in a "pin" shape.

[0056] By adopting the above technical solution, the structure of the shift fork display mechanism 100 is simplified while ensuring the normal rotation of the time dial 20.

[0057] It is understood that in other embodiments, the shift fork assembly 30 may be provided in three or more sets.

[0058] In some embodiments, the transmission system 40 includes a drive gear 44 and two sets of driven gears. The drive gear 44 is connected to the output shaft, and the two sets of driven gears are respectively arranged corresponding to two rotating members 33. The driven gear sets include a first driven gear 41 and a second driven gear 42 arranged coaxially. The diameter of the first driven gear 41 is greater than or less than the diameter of the second driven gear 42. The drive gear 44 is connected to the two first driven gears 41, and the two second driven gears 42 are respectively connected to the two rotating members 33.

[0059] Optionally, the transmission system 40 further includes an intermediate gear 43, with two sets of driven gears symmetrically arranged on both sides of the intermediate gear 43, and the driving gear 44 connected to the two driven gear sets through the intermediate gear 43. In other embodiments, the intermediate gear 43 may be omitted, and the two sets of driven gears may be symmetrically arranged on both sides of the driving gear 44, with the driving gear 44 connected to the two driven gear sets through the intermediate gear 43.

[0060] The first driven gear 41 and the second driven gear 42 are coaxially fixed to the fourth rotating shaft 16 by screws, the intermediate gear 43 is fixed to the fifth rotating shaft 17 by screws, and the driving gear 44 is used to fix to the output shaft of the basic movement.

[0061] The driving gear 44, intermediate gear 43, and first driven gear 41 are of the same type, meaning they have the same diameter and number of teeth. However, the diameter of the first driven gear 41 is larger than that of the second driven gear 42, and the number of teeth on the first driven gear 41 is twice the number of teeth on the second driven gear 42. In other embodiments, the diameter of the first driven gear 41 may be smaller than that of the second driven gear 42.

[0062] The base clamping plate 10 is provided with a placement groove 18, in which the driving gear 44, intermediate gear 43 and first driven gear 41 are all located.

[0063] During operation, the output shaft of the basic movement drives the drive gear 44 to rotate, the drive gear 44 drives the intermediate gear 43 to rotate, the intermediate gear 43 drives two sets of driven gears to rotate, and the two sets of driven gears drive two rotating parts 33 to rotate respectively, so that the power is transmitted from the output shaft of the basic movement to the shift fork assembly 30.

[0064] like Figure 2 and Figure 4As shown, at a certain moment, the left drive column 21 moves to the slot 322 of the left shift fork 32, and simultaneously, the right drive column 21 moves to the slot 322 of the right shift fork 32. The drive gear 44 continues to rotate, and the slot 322 of the left shift fork 32 begins to approach the left drive column 21, allowing the left drive column 21 to enter the sliding groove 321 of the left shift fork 32, while the slot 322 of the right shift fork 32 begins to move away from the right drive column 21. Afterward, the drive gear 44 continues to rotate, and the slot 322 of the left shift fork 32 begins to move the left drive column 21, causing the clock face 20 to rotate counterclockwise. As the drive gear 44 continues to rotate, the slot 322 of the left shift fork 32 begins to move away from the left drive post 21; the slot 322 of the right shift fork 32 begins to move closer to the right drive post 21, allowing the right drive post 21 to enter the sliding groove 321 of the right shift fork 32 and actuate the right drive post 21, causing the clock face 20 to continue rotating counterclockwise. This process repeats alternately, driving the clock face 20 to maintain its counterclockwise rotation.

[0065] Since the first driven gear 41 and the second driven gear 42 are arranged coaxially, and the diameter of the first driven gear 41 is greater than or less than the diameter of the second driven gear 42, the overall structure of the driving gear 44, the intermediate gear 43, the driven gear set and the rotating component 33 can be made more compact.

[0066] It is understood that in other embodiments, the transmission system 40 may be a belt drive, chain drive, worm gear drive, electric drive, or a composite drive.

[0067] In some embodiments, the rotating member 33 is a rotating gear, and the end of the shift fork 32 is eccentrically rotatably connected to the rotating gear.

[0068] The rotating gear meshes with the second driven gear 42, and the number of teeth on the rotating gear is twice the number of teeth on the second driven gear 42. The end of the shift fork 32 is eccentrically rotatably connected to the rotating gear.

[0069] Because the rotating gear has good stability when rotating, it ensures the stability of the shift fork 32's rotation, thereby avoiding jamming when the sliding groove 321 of the shift fork 32 engages with the transmission column 21.

[0070] It is understood that in other embodiments, the rotating component 33 includes a rotating gear and a transmission rod, the transmission rod being fixed to one axial side of the rotating gear, the rotating gear meshing with the second driven gear 42, and the end of the shift fork 32 being rotatably connected to the transmission rod. Of course, if the transmission system 40 is a belt drive or chain drive, the rotating gear can be replaced by a rotating pulley or a rotating sprocket.

[0071] In some embodiments, the shift fork display mechanism 100 further includes a split disk 50, which is fixed to the output shaft or the drive gear 44, and the rotation speed of the split disk 50 is twice the rotation speed of the rotating member 33.

[0072] The minute dial 50 is a circular disc with minute markings 51. It can be understood that the diameter of the minute dial 50 can be greater than, equal to, or less than the diameter of the hour dial 20.

[0073] The sub-disc 50 and the hour disc 20 are located on opposite sides of the plane containing the rotation axes of the two rotating components 33, that is, the sub-disc 50 and the hour disc 20 are located on opposite sides of the center of the base clamping plate 10.

[0074] Since the dial 50 is fixed on the output shaft, the dial 50 and the clock dial 20 are located on opposite sides of the center of the base plate 10, which is beneficial to the layout of the shift fork display mechanism 100 and improves the aesthetics of the shift fork display mechanism 100.

[0075] It is understood that in other embodiments, the distributor 50 may be fixed to the drive gear 44.

[0076] In some embodiments, twelve drive columns 21 are arranged at circumferential intervals along the clock face 20.

[0077] Each drive column 21 is positioned between two adjacent hour markers 22.

[0078] By adopting the above technical solution, the number of transmission columns 21 corresponds to the number of hours on the clock face 20, thus ensuring that the engagement process between each set of shift fork assemblies 30 and transmission columns 21 is exactly one hour.

[0079] It is understood that in other embodiments, six transmission columns 21 can be provided, in which case the engagement process between a set of shift fork assemblies 30 and the transmission columns 21 takes exactly two hours. Of course, the number of transmission columns 21 can also be arranged according to the number of shift fork assemblies 30.

[0080] In some embodiments, the end of the positioning post 31 away from the base clamping plate 10 is provided with a limiting part 311 to prevent the shift fork 32 from moving axially along the positioning post 31.

[0081] Optionally, such as Figure 3 As shown, the positioning pin 31 is a positioning pin with a head, which constitutes a limiting part 311. Of course, the positioning pin may also not have a head, but instead have a through hole extending radially at its end, in which a cotter pin is installed, which constitutes the limiting part 311.

[0082] It is understandable that the locating pin can be threaded onto the second rotating shaft 14, or the locating pin can be interference-fitted onto the second rotating shaft 14.

[0083] By adopting the above technical solution, the axial movement of the shift fork 32 along the positioning post 31 can be restricted, thus ensuring the stability of the shift fork 32.

[0084] In some embodiments, the groove 322 of the slide 321 is a flared opening.

[0085] The width of the end of the flared opening closest to the rotating hole 323 is smaller than the width of the end of the flared opening furthest from the rotating hole 323.

[0086] By adopting the above technical solution, it is beneficial for the transmission column 21 on the dial 20 to enter and exit the slide groove 321 on the shift fork 32.

[0087] In some embodiments, the base plate 10 is provided with an hour arrow 11 indicating the hour mark 22 on the dial 20.

[0088] like Figure 2 As shown, the hour arrow 11 is located at the top center of the hour dial 20.

[0089] By adopting the above technical solution, the hour mark 22 on the hour dial 20 can be accurately indicated, ensuring the accuracy of time reading on the hour dial 20.

[0090] In some embodiments, the base plate 10 is provided with a minute arrow 12 indicating the minute scale 51 on the dial 50.

[0091] like Figure 2 As shown, minute arrow 12 is located at the bottom center of hour dial 20.

[0092] The second aspect of this application discloses a fork-display watch. The fork-display watch includes a base movement and a fork-display mechanism 100 as described in the first aspect. The base movement has an output shaft, and the fork-display mechanism 100 includes a base plate 10, a dial 20, a transmission system 40, and at least two sets of fork assemblies 30. The output shaft of the base movement is the minute wheel shaft of the base movement.

[0093] The dial 20, the transmission system 40, and at least two sets of shift fork assemblies 30 are located on one side of the base plate 10, while the base movement is located on the other side of the base plate 10. The base plate 10 is provided with clearance holes for the output shaft of the base movement to pass through. The output shaft of the base movement is connected to the transmission system 40 to drive the shift fork assemblies 30.

[0094] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
