Description

Technical Field

[0001] This utility model belongs to the field of watch manufacturing technology, and in particular relates to a watch movement and a watch. Background Technology

[0002] With societal development and rising aesthetic standards, watches are no longer merely seen as timekeeping tools, but have gradually become important carriers of the wearer's personal style and identity. In recent years, some watch designs have emerged that enhance visual appeal through dynamic display elements, such as rotating dials or hands pointing to specific areas to indicate the date or time. While these designs visually enhance the watch's aesthetics and enjoyment, their internal structures are often quite complex, relying on multi-stage transmissions or asymmetrical drive mechanisms. This can easily lead to issues like vibration and inconsistent movement, ultimately affecting the movement's accuracy and long-term reliability.

[0003] Furthermore, the complex mechanical structure also brings disadvantages such as high assembly difficulty, increased failure rate, and increased manufacturing costs. Especially under high-frequency vibration or long-term operation, backlash accumulation and inaccurate positioning may lead to display errors or functional failures, seriously affecting the user experience. Therefore, how to simplify the transmission structure, improve the smoothness of movement, and ensure accurate timekeeping while maintaining visual appeal has become a key challenge in the design of this type of watch movement.

[0004] Therefore, there is an urgent need for a watch movement and watch that is simple in structure, has stable movement, and keeps accurate time. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a watch movement and watch that can achieve dynamic display of the character dial while possessing a simpler, more stable, and more reliable transmission mechanism, thereby improving the overall performance and lifespan of the movement. It has the advantages of simple structure, smooth movement, and accurate timekeeping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A watch movement, comprising:

[0008] Basic movement;

[0009] A base is provided on the basic movement, the base has a connecting hole in the middle, and the upper edge of the base has teeth and a limiting part;

[0010] A turntable assembly is provided on the upper end of the base. The turntable assembly includes an outer disk and a plurality of character disks rotatably disposed on the outer disk. The outer disk is connected to the power output end of the base movement through the connecting hole. The outer disk rotates under the drive of the base movement. Gears are coaxially connected to the lower end of the character disks. The gears abut against the upper edge of the base.

[0011] When the gear abuts against the limiting part, the character disk and the outer disk are fixed relative to each other; when the gear passes the tooth part, the character disk rotates relative to the outer disk.

[0012] Furthermore, the character disk is provided with several character areas. When the gear abuts against the limiting part, one of the character areas on the character disk is close to the edge of the outer disk.

[0013] Furthermore, the upper edge of the base is surrounded by a protruding edge that protrudes from the upper surface of the base, and the limiting portion is formed on the inner side of the protruding edge. The toothed portion includes a plurality of notches and protruding teeth formed on the inner side of the protruding edge.

[0014] Furthermore, the gear includes a plurality of tooth roots and tooth grooves disposed between two adjacent tooth roots. When two adjacent tooth roots abut against the limiting part, the character disk and the outer disk are relatively fixed.

[0015] Furthermore, the gear has four tooth roots evenly distributed on it, and the tooth portion includes three notches formed on the inner side of the convex edge and a convex tooth disposed between two adjacent notches. When the gear passes through the tooth portion, the tooth root corresponds to the notch and the tooth groove corresponds to the convex tooth, so that the gear rotates 270 degrees around its own axis.

[0016] Furthermore, the outer disk has three character disks evenly distributed on it, and each character disk has four character areas evenly distributed on it. Each character area is provided with an indicator point, and one of the indicator points of the character area is close to the edge of the outer disk.

[0017] Furthermore, the upper surfaces of the outer disk and the character disk are convex curved surfaces, and the angle between the rotation axis of the character disk and the rotation axis of the outer disk is greater than 0 degrees and less than 90 degrees.

[0018] Furthermore, the first rotating shaft on the back of the character disk passes through the positioning hole on the outer disk, is mounted onto the outer disk, and is connected to the irregular hole at the center of the gear.

[0019] Furthermore, the second rotating shaft at the center of the inner end of the outer disc passes through the connecting hole and is connected to the power output end of the basic movement through a connector.

[0020] This utility model also provides a watch, including a case and a watch movement, wherein the watch movement is installed inside the case, and an arc-shaped scale is provided at the edge of the upper surface of the case, and the character dial and the arc-shaped scale cooperate to indicate the time.

[0021] The beneficial effects of this utility model are:

[0022] This invention achieves smooth movement of the turntable assembly during overall rotation and character disc rotation by setting a base with limiting parts and teeth, and gears that cooperate with both. The limiting parts and teeth are integrated by a surrounding convex edge, which is easy to process and assemble. By adopting a layout of three character discs, each with four character areas, multiple display units can be driven simultaneously using a simplified mechanism, allowing the watch to display richer information. By setting arc-shaped scales on the case, the watch can intuitively, clearly, and stably indicate the time by using the cooperation between the character discs and the arc-shaped scales. This invention can achieve the dynamic display function of the character disc while having a simpler, more stable, and reliable transmission mechanism, thereby improving the overall performance and service life of the movement. It has the advantages of simple structure, smooth movement, and accurate timekeeping. Attached Figure Description

[0036] See appendix Figure 1 To be continued Figure 8The illustration shows a specific embodiment of the watch movement and watch provided by this utility model.

[0037] See appendix Figure 1 and attached Figure 2 The watch movement includes:

[0038] Basic movement 1;

[0039] A base 2 is provided on the base movement 1. A connecting hole 210 is provided in the middle of the base 2. A toothed part 220 and a limiting part 230 are provided on the upper edge of the base 2.

[0040] The turntable assembly 3 is located on the upper end of the base 2. The turntable assembly 3 includes an outer disk 310 and a plurality of character disks 320 rotatably disposed on the outer disk 310. The outer disk 310 is connected to the power output end of the base movement 1 through a connecting hole 210. The outer disk 310 rotates under the drive of the base movement 1. The lower end of the character disks 320 is coaxially connected to a gear 330, and the gear 330 abuts against the upper edge of the base 2.

[0041] When the gear 330 abuts against the limiting part 230, the character disk 320 and the outer disk 310 are fixed relative to each other; when the gear 330 passes the tooth part 220, the character disk 320 rotates relative to the outer disk 310.

[0042] See appendix Figure 1 and attached Figure 2 In the above embodiments, the base movement 1 is a mechanical movement, such as ETA 2824 or MIYOTA 9015. Its intermediate and hour wheels are modified, and the modified base movement 1's power output completes one revolution in 2, 3, or 4 hours, etc. (See appendix.) Figure 6 After the second rotating shaft 312 at the inner center of the outer disk 310 passes through the connecting hole 210, it is connected to the power output end of the base movement 1 through the connector 4. When the power output end of the base movement 1 rotates, the outer disk 310 is driven to rotate on the base 2 through the connector 4, and the several character disks 320 distributed on the outer disk 310 also revolve relative to the second rotating shaft 312. During rotation, the gear 330 connected to the lower end of the character disk 320 also moves synchronously with the character disk 320. When the gear 330 abuts against the limiting part 230, the character disk 320 and the outer disk 310 are relatively fixed. At this time, the character disk 320 can be used to indicate the hour. When the gear 330 passes the tooth part 220, the gear 330 meshes with the tooth part 220. Since the tooth part 220 is fixed and the gear 330 is rotatable, the gear 330 rotates relative to its own axis. Therefore, the character disk 320 also rotates relative to its own axis, that is, the character disk 320 rotates relative to the outer disk 310.

[0043] See appendix Figure 1 and attached Figure 2 In the above embodiment, the character disk 320 is provided with a plurality of character areas 321. When the gear 330 abuts against the limiting part 230, one of the character areas 321 on the character disk 320 is closer to the edge of the outer disk 310. In this embodiment, each character area 321 on the character disk 320 is used to display an hour character. When the gear 330 abuts against the limiting part 230, the character on the character area 321 closer to the edge of the outer disk 310 is used to indicate the current hour reading. When the gear 330 passes the tooth part 220, the character disk 320 rotates and switches to another character area 321 closer to the edge of the outer disk 310. In this embodiment, taking 12 hours as an example, when there are 2 character disks 320 on the outer disk 310, each character disk 320 can have 6 character areas 321; when there are 3 character disks 320, each character disk 320 can have 4 character areas 321; when there are 4 character disks 320, each character disk 320 can have 3 character areas 321.

[0044] See appendix Figure 3 and attached Figure 4 In the above embodiment, a raised edge 240 protruding from the upper surface of the base 2 is provided around the upper edge of the base 2. A limiting portion 230 is formed on the inner side of the raised edge 240. The tooth portion 220 includes a plurality of notches 221 and protruding teeth 222 formed on the inner side of the raised edge 240. In the embodiment, the inner side of the raised edge 240, i.e., the inner ring portion, is the limiting portion 230. When the gear 330 abuts against the limiting portion 230 and the outer disk 310 is in a rotating state, the gear 330 slides on the inner side of the raised edge 240. When the gear 330 passes through the tooth portion 220 composed of notches 221 and protruding teeth 222, the gear 330 rotates by engaging with the notches 221 and protruding teeth 222, thereby achieving the effect of driving the character disk 320 to rotate.

[0045] See appendix Figure 3 and attached Figure 4 In the above embodiment, the gear 330 includes a plurality of tooth roots 331 and tooth grooves 332 disposed between two adjacent tooth roots 331. When two adjacent tooth roots 331 abut against the limiting part 230, the character disk 320 and the outer disk 310 are relatively fixed. In the embodiment, when two adjacent tooth roots 331 abut against the inner side of the limiting part 230, i.e., the protrusion 240, the gear 330 cannot rotate and can only be in a state of sliding abutting against the inner side of the protrusion 240.

[0046] See appendix Figure 3 and attached Figure 4In the above embodiment, the gear 330 has four tooth roots 331 evenly distributed on it. The tooth portion 220 includes three notches 221 formed on the inner side of the flange 240 and a tooth 222 disposed between two adjacent notches 221. When the gear 330 passes through the tooth portion 220, the tooth roots 331 correspond to the notches 221, and the tooth grooves 332 correspond to the tooth 222, so that the gear 330 rotates 270 degrees around its own axis. In the embodiment, when the gear 330 revolves clockwise to the left side of the tooth portion 220, the two tooth roots 331 of the gear 330 abut against the inner side of the flange 240, and the tooth grooves 332 between the two tooth roots 331 are opposite to the inner side of the flange 240. The gear 330 continues to move clockwise until one of the tooth roots 331 falls into the first notch 221 on the left. When the gear 330 continues to move, due to the obstruction of the tooth 222, the gear 330 rotates counterclockwise. When the tooth groove 332 of gear 330 corresponds to the first tooth 222, gear 330 has rotated 90 degrees counterclockwise compared to when it was to the left of tooth 220; gear 330 continues to revolve, and when the tooth groove 332 of gear 330 corresponds to the second tooth 222, gear 330 has rotated 180 degrees counterclockwise compared to when it was to the left of tooth 220; gear 330 continues to revolve, and when gear 330 disengages from the third notch 221, gear 330 has rotated 270 degrees counterclockwise compared to when it was to the left of tooth 220.

[0047] See appendix Figure 2 and attached Figure 3 In the above embodiment, three character discs 320 are evenly distributed on the outer disc 310, and four character areas 321 are evenly distributed on each character disc 320. Each character area 321 is provided with an indicator point 322, and the indicator point 322 of one of the character areas 321 is close to the edge of the outer disc 310. In the embodiment, the character areas 321 on the first character disc 320 are marked with 1, 4, 7, and 10 clockwise, the character areas 321 on the second character disc 320 are marked with 2, 5, 8, and 11 clockwise, and the character areas 321 on the third character disc 320 are marked with 3, 6, 9, and 12 clockwise. The power output end of the basic movement 1 rotates once, which is equivalent to 3 hours. When the basic movement 1 drives the outer disc 310 to rotate once, each character disc 320 indicates one hour, that is, the three character discs 320 are read sequentially as 1, 2, and 3. Then, the gear 330 of the first character disk 320 rotates 270 degrees through the tooth 220, causing the reading of the first character disk 320 near the edge of the outer disk 310 to change from 1 to 4, and then enters the second cycle, thereby achieving the effect of cyclically indicating the hour time.

[0048] See appendix Figure 5In the above embodiment, the upper surfaces of the outer dial 310 and the character dial 320 are convex curved surfaces, and the angle between the rotation axis of the character dial 320 and the rotation axis of the outer dial 310 is greater than 0 degrees and less than 90 degrees. Specifically, the upper surfaces of the outer dial 310 and the character dial 320 are spherical. This embodiment achieves better utilization of the space above the dial, while enhancing the three-dimensionality and aesthetics of the watch.

[0049] See appendix Figure 7 In the above embodiment, the first rotating shaft 323 on the back of the character disk 320 passes through the positioning hole 311 on the outer disk 310 and is installed on the outer disk 310, and connected to the irregular hole 333 at the center of the gear 330. In this embodiment, by using the first rotating shaft 323 to pass through the outer disk 310 to connect the character disk 320 and the gear 330, the modular installation and fixation of the character disk 320 component is realized, which facilitates assembly and maintenance, while ensuring the concentricity and stability of the rotational connection.

[0050] This embodiment also provides a watch, including a housing 5 and the aforementioned watch movement. The watch movement is installed inside the housing 5. An arc-shaped scale 510 is provided on the edge of the upper surface of the housing 5. The character dial 320 and the arc-shaped scale 510 cooperate to indicate the time. In this embodiment, the arc-shaped scale 510 is marked with minute graduations from 0 to 60. The length of the arc-shaped scale 510 on the outer ring of the dial of the housing 5 is one-third of the circumference of the dial of the housing 5. When the character dial 320 rotates to the area where the arc-shaped scale 510 is located, the number corresponding to the indicator point 322 pointing to the arc-shaped scale 510 is used for hour reading, and the specific value on the arc-shaped scale 510 pointed to by the indicator point 322 is the minute reading. The two work together to achieve the reading of the specific time.

[0051] In summary, this embodiment provides a watch movement and a watch. By setting a base 2 with a limiting part 230 and a toothed part 220, and a gear 330 that cooperates with both, the smooth movement of the turntable assembly 3 during overall rotation and the rotation of the character disc 320 is achieved. The limiting part 230 and the toothed part 220 are integrally formed by the surrounding convex edge 240, which is easy to process and assemble. By adopting a layout of three character discs 320, each with four character areas 321, multiple display units can be driven simultaneously using a simplified mechanism, enabling the watch to display richer information. By setting an arc-shaped scale 510 on the housing 5, the watch can intuitively, clearly and stably indicate the time by cooperating with the character disc 320 and the arc-shaped scale 510. This embodiment can achieve the dynamic display function of the character disc 320 while having a simpler, more stable and reliable transmission mechanism, thereby improving the overall performance and service life of the movement. It has the advantages of simple structure, smooth movement and accurate timekeeping.

[0052] The embodiments described above are merely one of the preferred embodiments of this utility model.
