Description

Technical Field

[0001] The present invention belongs to the field of watch structures, and particularly relates to an opening and closing structure for a watch dial. Background Art

[0002] With the rapid development of the technology era, watches have evolved from single-timekeeping tools into daily wearable items that combine practicality and aesthetics. People's demands for watches are no longer limited to functionality, but they also pursue their design aesthetics, interactive fun, and the ornamental value of mechanical craftsmanship. However, the existing watch designs are mostly limited to traditional forms, and the opening and closing structures of watch dials generally use single gears or linkages for driving, resulting in monotonous movements, lack of dynamic expressiveness, and difficulty in meeting users' demands for personalization and artistry. In addition, traditional mechanical transmission systems are often restricted by bulky structures and low transmission efficiency, which limits miniaturization design, and are prone to problems such as asynchronous opening and closing, jamming, or incomplete closing, which not only affect the user experience but also weaken the precise beauty of the mechanical structure. There is an urgent need for a new type of watch dial opening and closing structure that combines fun, ornamental value, and efficient mechanical transmission. On the premise of ensuring a compact structure and stable operation, through innovative transmission logic and dynamic design, it provides users with a wearable experience that combines a sense of technology and artistic value.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0033] As Figures 1-5As shown in the figure, the present invention discloses a dial opening and closing structure, including a housing 1. The housing 1 is in the shape of a pot lid with an upward opening and a hexagonal top view. The peripheral wall is composed of multiple triangles. A driving member 2 and a driving plate 3 are provided inside the housing 1. The driving member 2 is a motor, and both partially penetrate the bottom of the housing 1. Outside the bottom of the housing 1, the driving member 2 is fixedly connected to a worm 4 and provides power to it. The worm 4 is cylindrical in shape, with its top fixedly connected to the driving member 2 and extending downward. The peripheral wall is distributed with racks extending spirally along the direction of the rod. A corresponding turbine 41 is provided on one side of the worm 4. The racks of the turbine 41 and the worm 4 are engaged with each other. The main tooth block 31 is provided on the downward extending part of the driving plate 3 and contacts the turbine 41. The main tooth block 31 is rectangular in shape, with its top fixedly connected to the driving plate 3. Racks are provided on the contact surface with the turbine 41. The racks on the main tooth block 31 and the turbine 41 are engaged with each other. Inside the housing 1, a plurality of secondary tooth blocks 32 are provided around the driving plate 3. The secondary tooth blocks 32 are also rectangular and are provided with racks. And a petal assembly 5 corresponding to each secondary tooth block 32 is provided outside the housing 1. A gear 6 penetrating the housing 1 is provided between the secondary tooth block 32 and the petal assembly 5. One end of the gear 6 is engaged with the rack on the secondary tooth block 32, and the other end is connected to the petal assembly 5.

[0034] Among them, in the closed state, a plurality of the petal assemblies 5 wrap the peripheral wall and the top of the housing 1. When the driving member 2 starts to operate, it provides a self-rotation power to the worm 4. The spiral rack on the worm 4 moves downward and drives the turbine 41 to rotate, synchronously driving the main tooth block 31 on one side of the turbine 41 to move upward and eject. The driving plate 3 at the top of the main tooth block 31 is synchronously pushed upward under the thrust, and synchronously drives a plurality of the tooth blocks 32 fixedly connected around it to move upward. The gear 6 engaged with the secondary tooth block 32 starts to rotate under the thrust, and synchronously drives the petal assembly 5 connected to the gear 6 to separate from the peripheral wall and the top of the housing 1, and finally completes the blooming. It should be noted that during the whole process, the housing 1 is fixed. In the blooming state, the petal assemblies 5 no longer wrap the peripheral wall and the top of the housing 1, but "bloom one by one and simultaneously" around the outside of the housing 1. The whole process is like a flower blooming from closed to open. And the dial opening and closing structure is one of the components in a watch. When the watch is worn, the dial opening and closing structure is in the closed state. When the watch is taken off, the dial opening and closing structure is in the blooming state.

[0035] Specifically, as Figure 6As shown in the figure, in an embodiment of the present invention, one side of the axis of the gear 6 is fixedly connected to the disc portion 53 extending from the petal assembly 5 through a fixing member 11 fixed on the peripheral wall of the housing 1. From left to right are the gear 6, the disc portion 53 of the petal assembly 5, and the fixing member 11. It should be noted that the gear 6 and the petal assembly 5 are fixedly connected, and the two are rotatably connected relative to the fixing member 11. This structural design enables the gear 6 to drive the petal assembly 5 to rotate synchronously when the gear 6 rotates. At the same time, the gear 6 and the petal assembly 5 are mainly fixed on the housing 1 through the fixing member 11.

[0036] Further, as Figure 7 shown, the petal assembly 5 includes large petals 51 and small petals 52, and the outer shapes of both are approximately triangular structures. Among them, in the gear 6 fixedly connected to the petal assembly 5, there are a large gear 61 and a small gear 62 corresponding to the large petals 51 and the small petals 52 respectively, and the diameter of the large gear 61 is greater than the diameter of the small gear 62. This structural design enables the rotation speed of the small petals 52 to be greater than the rotation speed of the large petals 51 during the blooming process. At the same time, because the volume of the small petals 52 is smaller than the volume of the large petals 51, it is more in line with the process of "flower blooming" in terms of visual perception.

[0037] Specifically, as Figure 8 shown, in an embodiment of the present invention, in addition to being rotatably connected to the housing 1 through the fixing member 11, a connecting rod 7 is provided between the large petals 51. Both ends of the connecting rod 7 are rotatably connected to the connections between the housing 1 and the large petals 51 through a first connecting member 71 and a second connecting member 72 respectively. The first connecting member 71 is fixed on the peripheral wall of the housing 1 above the large gear 61, and the second connecting member 72 is fixed on the large petals 51. This structural design enables the large gear 61 to drive the large petals 51 to rotate around the fixing member 11 to a certain angle. At this time, the connecting rod 7 will provide a pulling force to the large petals 51, causing the large petals 51 to stop rotating. It should be noted that when the large petals 51 stop rotating, they drive the large gear 61 to stop rotating, indirectly causing the drive plate 3, the small gear 62, and the small petals 52 to stop rotating.

[0038] Specifically, as Figures 9-11As shown in the figure, in an embodiment of the present invention, the large petal 51 includes a first support member 511 and a second support member 512. One end of the first support member 511 is fixedly connected to the large gear 61, and the other end is rotatably connected to the second support member 512. The first support member 511 and the second support member 512 can be opened and closed to form different angles. When the dial is in the closed state, the first support member 511 of the large petal 51 and the small petal 52 wrap around the outer peripheral wall of the housing 1, and the second support members 512 of the large petal 51 jointly surround and wrap the top of the housing 1. At this time, the angle formed by the first support member 511 and the second support member 512 is an acute angle. When in the blooming state, the angle formed by the first support member 511 and the second support member 512 is an obtuse angle. This structural design makes the process of the large petal 51 "blooming" from a bud to a petal more vivid and aesthetically pleasing in appearance.

[0039] Specifically, as Figures 9-11 shown, in an embodiment of the present invention, the connecting rod 7 is rotatably connected to the large petal 51 through the second connecting member 72 and acts on the second support member 512, that is, the second connecting member 72 is fixed on the second support member 512, and a first rotating shaft 513 is provided at the rotating connection between the connecting rod 7 and the second support member 512. The rotating connection between the second support member 512 and the first support member 511 is also on the second support member 512 and is provided with a second rotating shaft 514. The first rotating shaft 513 and the second rotating shaft 514 are not coaxial. On the second support member 512, the position of the former is lower than that of the latter and closer to the bottom of the latter. The function of this mechanism design is that in the closed state, the angle formed by the first support member 511 and the second support member 512 is an acute angle, and during the initial blooming process, the connecting rod 7 will continuously apply a pulling force to the second support member 512 to continuously increase the opening and closing angle between the first support member 511 and the second support member 512, and finally form an obtuse angle when the blooming state is completed.

[0040] Furthermore, as Figures 9-11 shown, a through hole 515 is provided on the first support member 511. In the closed state, the second support member 512 covers the top of the housing 1, the second support member 512 is in a horizontal state, and the second rotating shaft 514 and the first rotating shaft 513 therein are also in a horizontal state. At this time, the second rotating shaft 514 is farther from the center of the top of the housing 1 than the first rotating shaft 513 and the first support member 511. In addition, since the second rotating shaft 514 is also connected to the connecting rod 7 at this time, it is necessary to provide the through hole 515 on the first support member 511 so that the second rotating shaft 514 and the connecting rod 7 can pass through the first support member 511 without affecting their rotation during the subsequent blooming process.

[0041] Specifically, as Figure 12 shown, in an embodiment of the present invention, a placement groove 33 for placing the slave tooth block 32 is provided on the driving plate 3. The placement groove 33 and the driving plate 3 are integrally formed to wrap the slave tooth block 32, and only the side of the slave tooth block 32 provided with the rack engages with the gear. This structural design, on the one hand, enables the slave tooth block 32 to be more firmly fixed on the driving plate 3, avoiding the detachment of the slave tooth block 32 due to long-term sliding. On the other hand, when the rack on the slave tooth block 32 wears or slips after long-term use, it is more convenient to replace the slave tooth block 32. If the slave tooth block 32 and the driving plate are of an integral structure, the cost will increase when replacement is needed.

[0042] The following is a detailed description of the working principle of the present invention:

[0043] The operation of the dial opening and closing structure of the present invention is based on a precision mechanical transmission system. In the closed state, the petal assembly 5 fits on the outer peripheral wall and the top of the housing 1 to form a sealed protection. After the driving member 2 is started, the worm 4 is driven to rotate by the driving member 2, and the spiral rack drives the 41 turbine engaged with it to rotate synchronously. The rotation of the turbine 41 further pushes the main tooth block 31 to move axially, thereby driving the entire driving plate 3 fixed thereto to rise. The slave tooth blocks 32 evenly distributed on the driving plate 3 move upward synchronously. Each slave tooth block 32 engages with the corresponding gear 6 through the rack, forcing the gear 6 to rotate around the fixed axis. The rotation of the gear 6 directly drives the petal assembly 5 to unfold outward. The design of the diameter difference between the large gear 61 and the small gear 62 enables the unfolding speed of the small petal 52 to be faster than that of the large petal 51, simulating the blooming sequence of natural flowers. The large petal 51 is hinged to the housing 1 through the connecting rod 7. When the gear 6 drives the large petal 51 to rotate to a preset angle, the connecting rod 7 provides a reverse pulling force to stop it, ensuring that the opening and closing angle is accurately controllable. During the whole process, the housing 1 remains stationary, and only the petal assembly 5 is controlled to move, finally realizing the dynamic conversion from closed to fully blooming. When closing in the reverse direction, the driving member rotates in reverse, and the transmission chain runs in reverse, and the petal assembly 5 fits on the housing 1 again to restore the initial state.

[0044] The innovation of the present invention lies in: through the meshing of worm and turbine and the collaborative drive of multi-stage gear sets, the present invention significantly improves the transmission efficiency and stability, avoiding the jamming and out-of-sync problems of traditional structures. By adopting the hierarchical drive design of the main tooth block and the slave tooth block and combining the different diameters of large and small gears, the sequential unfolding of the petal assembly is realized, simulating the visual effect of the blooming of natural flowers. The connecting rod and the double-rotating shaft structure precisely limit the opening and closing angles of the large petals, ensuring that the action end point is controllable and avoiding overshoot or incomplete closing. The modular drive plate and the slave tooth block adopt a split mounting groove, facilitating the rapid replacement of worn parts and reducing the maintenance cost. In addition, the multi-segment articulated design of the petal assembly enhances the structural compactness, meeting the requirements of miniaturized dials. At the same time, the spatial layout is optimized through through-holes and rotating shafts, taking into account both mechanical strength and aesthetic performance. While simplifying the transmission chain, the overall structure significantly improves the reliability, durability and user experience.
