[0002] For the general public, watches are no longer just a tool to indicate time, but more of a decorative accessory or wearable accessory. Watches can be divided into mechanical watches and quartz watches. Quartz watches can be divided into pointer quartz watches and electronic quartz watches. Unlike electronic quartz watches, traditional pointer watches cannot display "digital time" through chips and LCD screens. Instead, they use the hour, minute, and second hands connected to the movement shaft and fixed time symbols to display the current hour, minute, and second. This has greatly restricted the appearance design of traditional pointer watches, and there are very few watches that break this traditional display method, resulting in a strong similarity in the appearance design of pointer watches, which is easy to cause aesthetic fatigue.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] In order to illustrate the technical solution of the present invention, a detailed description is given below in conjunction with specific drawings and embodiments.

[0030] See also Figures 1 to 6 An embodiment of the present invention provides a dial structure for displaying the current time, including a first outer ring 12 and a first surrounding gear 11 arranged in the first outer ring 12. The dial structure has a rotating axis. The inner side of the first outer ring 12 is provided with a first tooth structure 121 along its circumferential direction. The first surrounding gear 11 is meshed with the first tooth structure 121. The first outer ring 12 can rotate around the rotating axis, and the first surrounding gear 11 can rotate around its own axial direction and revolve around the rotating axis at the same time.

[0031] In the dial structure provided by the embodiment of the present invention, a toothed structure is arranged on the inner side of the first outer ring 12, and the first surround gear 11 rotates around the rotation axis under the meshing action of the first central gear 13 and the toothed structure on the inner side of the first outer ring 12. Thus, among the self-rotation state of the first outer ring 12, the self-rotation state of the first surround gear 11, and the revolution state of the first surround gear 11, two states can be used to display time, and two time units can be displayed on the same layer of gear structure, thereby increasing the number of time units that can be displayed on the same layer of gear structure.

[0032] Two states can be selected for displaying time from the self-rotation state of the first outer ring 12, the self-rotation state of the first surrounding gear 11, and the revolution state of the first surrounding gear 11, which expands the mode of displaying time with the dial structure and allows various flexible and creative designs on the structure of the dial structure.

[0033] As a specific scheme of this embodiment, the first orbiting gear 11 moves under the control of the tie rod, and two rotation modes of the revolution of the first orbiting gear 11, the rotation of the first orbiting gear 11 and the rotation of the first outer ring 12 are controlled. When the two rotation modes are determined, since the first orbiting gear 11 is engaged with the first toothed structure 121, the third rotation mode is also determined accordingly. In this way, two states can be selected from the rotation state of the first outer ring 12, the rotation state of the first orbiting gear 11 and the orbital state of the first orbiting gear 11 to represent time.

[0034] See also Figure 2 , Figures 4 to 6 In one embodiment of the present invention, the dial structure also includes a first central gear 13 disposed in the first outer ring 12 and coaxially disposed with the first outer ring 12. The first central gear 13 can rotate around the rotation axis, and the first surrounding gear 11 is simultaneously engaged with the first central gear 13 and the first toothed structure 121.

[0035] By setting the first central gear 13 in the dial structure, the first surround gear 11 is meshed with the first central gear 13 and the first tooth structure 121 of the first outer ring 12 at the same time. In this way, two states can be selected from the rotation state of the first outer ring 12, the rotation state of the first central gear 13, the rotation state of the first surround gear 11 and the revolution state of the first surround gear 11 to display the time, which further expands the mode of displaying time of the dial structure and allows various flexible and creative designs to be made on the structure of the dial structure.

[0036] In one embodiment of the present invention, the dial structure further includes a movement (not shown in the figure), which drives the first outer ring 12 and the first central gear 13 to rotate respectively.

[0037] The first surrounding gear 11 tends to rotate around the first central gear 13, which means that a more complex mechanical structure is required to control the revolution and rotation of the first surrounding gear 11; for the dial structure provided in this embodiment, since the first surrounding gear 11 is meshed with the first central gear 13 and the first toothed structure 121 at the same time, when any two rotation modes of the rotation state of the first outer ring 12, the rotation state of the first central gear 13, the rotation state of the first surrounding gear 11 and the revolution state are controlled, the other two rotation states are also determined accordingly. Therefore, the rotation and revolution modes of the first surrounding gear 11 can be controlled by controlling the rotation mode of the first outer ring 12 and the rotation mode of the first central gear 13. Such a setting can ensure that two time units can be displayed on the same layer of gear structure without having to set a rod that rotates with the first surrounding gear 11 and is used to control the first surrounding gear 11, thereby simplifying the mechanical structure for controlling the timing operation of the dial structure.

[0038] In one embodiment of the present invention, two of the rotation state of the first outer ring 12, the rotation state of the first central gear 13, the rotation state of the first surrounding gear 11 and the revolution state of the first surrounding gear 11 respectively represent the hour information and minute information of the current time.

[0039] The dial structure provided in this embodiment can display two time units on the same gear structure. In the case of only one gear structure, the current hour and minute information is displayed first, which has a higher practical use value. As a preferred solution of this embodiment, the revolution state of the first surrounding gear 11 represents the hour information of the current time, and the rotation state of the first outer ring 12 represents the minute information of the current time. Such a setting is closer to the reading method of the traditional pointer watch and is more in line with the usage habits of general consumers.

[0040] See also Figures 3 to 6 In one embodiment of the present invention, the dial structure also includes a second outer ring 22 and a second surrounding gear 21. The second outer ring 22 is arranged on one side of the first outer ring 12 and is coaxial with the first outer ring 12. The second surrounding gear 22 is arranged in the second outer ring 21. The second outer ring 22 rotates around the rotation axis. The inner side of the second outer ring 22 is provided with a second tooth structure 221 along its circumferential direction. The second outer ring 22 can rotate around the rotation axis. The second surrounding gear 21 is meshed with the second tooth structure 221. The second surrounding gear 21 can rotate around its own axial direction and revolve around the rotation axis at the same time.

[0041] A toothed structure is provided on the inner side of the second outer ring 22, and the second surround gear 21 rotates and revolves around the rotation axis under the meshing action of the second center gear 23 and the toothed structure on the inner side of the second outer ring 22. Thus, among the rotation state of the second outer ring 22 and the rotation state and the revolution state of the second surround gear 21, two states can be used to display the time, so that the dial structure can display two additional time information, further expanding the mode and flexibility of the dial structure in displaying the time; at the same time, the two-layer dial structure does not interfere with each other and moves in an interlaced manner, thereby enhancing the mechanical dynamics of the mechanical watch and improving the visual effect of the dial structure.

[0042] See also Figures 4 to 6 In one embodiment of the present invention, the dial structure further includes a first central gear 13 and a second central gear 23 which are coaxially arranged. The first central gear 13 and the second central gear 23 can rotate around the rotation axis. The first central gear 13 is arranged in the first outer ring 12, and the first surrounding gear 11 is meshed with the first central gear 13 and the first toothed structure 121 at the same time.

[0043] The second central gear 23 is disposed in the second outer ring 22 , and the second surround gear 21 is meshed with the second central gear 23 and the second toothed structure 221 of the second outer ring 22 at the same time.

[0044] By arranging the first center gear 13 and the second center gear 23 in the dial structure, the first surround gear 11 is meshed with the first center gear 13 and the first tooth structure 121 of the first outer ring 12 at the same time, and the second surround gear 21 is meshed with the second center gear 23 and the second tooth structure 221 of the second outer ring 22 at the same time. In this way, two states can be selected from the rotation state of the first outer ring 12, the rotation state of the first center gear 13, and the rotation state and the revolution state of the first surround gear 11 for displaying the time, and at the same time, two states can be selected from the rotation state of the second outer ring 22, the rotation state of the second center gear 23, and the rotation state and the revolution state of the second surround gear 21 for displaying the time, which further expands the mode of displaying time of the dial structure and allows various flexible and creative designs to be made on the structure of the dial structure.

[0045] In one embodiment of the present invention, the dial structure further includes a movement, which drives the rotation of the first outer ring 12, the rotation of the first central gear 13, the rotation of the second outer ring 22 and the rotation of the second central gear 23 respectively.

[0046] The first orbital gear 11 tends to rotate around the first center gear 13, and the second orbital gear 21 tends to rotate around the second center gear 23. This means that controlling the revolution and rotation of the first orbital gear 11 requires a more complex mechanical structure. Moreover, if the first orbital gear 11 and the second orbital gear 21 are controlled by a tie rod that rotates with the first orbital gear 11 and the second orbital gear 21, there will be a spatial contradiction between the tie rod controlling the upper gear and the lower gear, resulting in a collision and the gear cannot be controlled normally.

[0047] In one embodiment of the present invention, two states among the rotation state of the first outer ring 12, the rotation state of the first center gear 13, the rotation state of the first surround gear 11 and the revolution state of the first surround gear 11 each represent a time information; two states among the rotation state of the second outer ring 22, the rotation state of the second center gear 23, the rotation state of the second surround gear 21 and the revolution state of the second surround gear 21 each represent a time information.

[0048] Each layer of the outer ring and the gear structure can represent two time information. In the two layers of gears and the outer ring structure in this embodiment, the layers and the layer brackets are independent of each other, so a total of four time information can be represented, such as hours, minutes, seconds and weeks, or hours, minutes, years and months, etc. The way of representing time is more diverse and flexible.

[0049] As a specific solution of this embodiment, the rotation state of the first outer ring 12 and the rotation state of the second outer ring 22 respectively represent the hour and minute of the current moment, and the revolution state of the first surrounding gear 11 and the revolution state of the second surrounding gear 21 respectively represent the year and month of the current moment.

[0050] See also Figure 5 and Figure 6 In one embodiment of the present invention, the dial structure also includes a third outer ring 32, a third center gear 33 and a third surround gear 31. The third outer ring 32 is arranged on the side of the second outer ring 22 facing away from the first outer ring 12 and is coaxial with the first outer ring 12. The third surround gear 31 and the third center gear 33 are arranged in the third outer ring. The third outer ring 32 and the third center gear 33 can rotate independently around the rotation axis. A third tooth structure 321 is provided on the inner side of the third outer ring 32. The third surround gear 31 is meshed with the third center gear 33 and the third tooth structure 321 at the same time. The third surround gear 31 can rotate around its own axis and revolve around the rotation axis at the same time.

[0051] As a preferred solution of this embodiment, the dial structure also includes a third center gear 33 and a third surround gear 31. The control relationship among the third outer ring 32, the third center gear 33 and the third surround gear 31 is similar to that among the first outer ring 12, the first center gear 13 and the first surround gear 11. Compared with the two-layer dial structure, it can display two additional time units, further expanding the mode and flexibility of the dial structure in displaying time.

[0052] See also Figure 6 Another object of the present invention is to provide a watch including the dial structure as described above, the watch is provided with an observation window made of transparent material for the wearer to observe the rotation state of the outer ring of the dial and the surrounding gear; and a mark is provided at a position corresponding to the outer side of the dial structure to indicate the current rotation state of the outer ring.

[0053] The beneficial effects of the dial structure provided by the present invention are described below through some specific implementations. It should be understood that the following specific implementations only list several preferred technical solutions of the dial structure provided by the present invention, which are only optional embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0054] Embodiment 1

[0055] See also Figure 2 In this embodiment, the dial structure includes a first outer ring 12, a first central gear 13 and a first surrounding gear 11. The first outer ring 12 and the first central gear 13 rotate around the same rotation axis. A first tooth structure 121 is provided on the inner side of the first outer ring 12. The first surrounding gear 11 is meshed with the first central gear 13 and the first tooth structure 121 at the same time. The first surrounding gear 11 can rotate around its own axis while revolving around the first central gear 13. In this way, two time units can be displayed on the same layer of gear structure, which expands the mode of displaying time of the dial structure and can give the dial structure design more creativity and flexibility.

[0056] In this embodiment, the rotation mode of the first outer ring 12 of the first surrounding gear 11 and the rotation mode of the first central gear 13 are controlled to drive the rotation and revolution of the first surrounding gear 11. Since there is no need to design a tie rod to control the first surrounding gear 11, the control structure of the movement can be simplified.

[0057] In this embodiment, the rotation state of the first outer ring 12 is used to display minute information, and the revolution state of the first surrounding gear 11 is used to display hour information. Specifically, the first outer ring 12 rotates at a speed of 1 rotation per hour; the first central gear 13 rotates at a first speed in the opposite direction to the rotation of the first outer ring 12 according to the relationship between the number of teeth of the first outer ring 12, the first central gear 13 and the first surrounding gear 11, so that the first surrounding gear 11 revolves around the first central gear 13 at a speed of 30° per hour (or 15° per hour) under the meshing action of the first central gear 13 and the first outer ring 12. For example, the first center gear 13 and the first surround gear 11 have the same number of teeth, the first outer ring 12 has three times the number of teeth of the first center gear 13, and the first speed is 8 / 3 revolutions per hour (or 17 / 6 revolutions per hour). In this way, when the first center gear 13 rotates in the opposite direction to the first outer ring 12 at the first speed, the first surround gear 11 rotates in the same direction as the first outer ring 12 at a speed of 30° (or 15°) per hour. The rotation state of the first outer ring 12 displays the current minute number, and the revolution state of the first surround gear 11 displays the current hour information, and it rotates once every 12 hours (24 hours).

[0058] Embodiment 2

[0059] See also Figure 2 In this embodiment, the dial structure is the same as that in the first embodiment, and the rotation mode of the first outer ring 12 of the first surrounding gear 11 and the rotation mode of the first central gear 13 are controlled; the difference is that the rotation state of the first outer ring 12 is used to display the hour information, and the revolution state of the first surrounding gear 11 is used to display the minute information. Specifically, the first outer ring 12 rotates at a speed of 1 rotation every 12 hours; the first central gear 13 rotates at a suitable speed in the same direction as the rotation of the first outer ring 12 according to the relationship between the number of teeth of the first outer ring 12, the first central gear 13 and the first surrounding gear 11, so that the first surrounding gear 11 revolves around the first central gear 13 at a speed of 1 rotation per hour under the meshing action of the first central gear 13 and the first outer ring 12. More specific data such as the rotation speed can be calculated based on the relationship between the number of teeth of the first outer ring 12, the first central gear 13 and the first surrounding gear 11, which will not be repeated here.

[0060] Embodiment 3

[0061] See also Figure 2In this embodiment, the dial structure is the same as that in the first embodiment, and the rotation mode of the first outer ring 12 of the first surrounding gear 11 and the rotation mode of the first central gear 13 are controlled; the difference is that the rotation state of the first surrounding gear 11 is used to display minute information, and the revolution state of the first surrounding gear 11 is used to display hour information. Specifically, the first central gear 13 and the first outer ring 12 rotate at a suitable speed according to the relationship between the number of teeth of the first outer ring 12, the first central gear 13 and the first surrounding gear 11, so that the first surrounding gear 11 revolves around the first central gear 13 at a speed of one circle per 12 hours under the meshing action of the first central gear 13 and the first outer ring 12, and rotates at a speed of one circle per hour. More specific data such as the rotation speed can be calculated based on the relationship between the number of teeth of the first outer ring 12, the first central gear 13 and the first surrounding gear 11, which will not be repeated here. In this solution, since the rotation state of the first outer ring 12 is not used to display time, the first outer ring 12 can be shielded by the housing, while shielding other gear structures, making the appearance of the watch more concise.

[0062] Embodiment 4

[0063] See also Figure 4 In this embodiment, the dial structure includes a first outer ring 12, a first central gear 13 and a first surrounding gear 11. The first outer ring 12 and the first central gear 13 rotate around the same rotation axis. The first outer ring 12 is provided with a first tooth structure 121 inside. The first surrounding gear 11 is meshed with the first central gear 13 and the first tooth structure 121 at the same time. The first surrounding gear 11 can rotate around its own axis and revolve around the first central gear 13 at the same time. It also includes a second outer ring 22, a second central gear 23 and a second surrounding gear 21. The second outer ring 22 and the second central gear 23 rotate around the same two rotation axes. The second outer ring 22 is provided with a second tooth structure 221 inside. The second surrounding gear 21 is meshed with the second central gear 23 and the second tooth structure 221 at the same time. The second surrounding gear 21 can rotate around its own axis and revolve around the second central gear 23 at the same time. In this way, each outer ring and the corresponding gear structure can display two time states, and the dial structure can display four time states in total.

[0064] In this embodiment, the rotation mode of the first outer ring 12 of the first surround gear 11 and the rotation mode of the first center gear 13 are controlled, driving the rotation and revolution of the first surround gear 11; the rotation mode of the second outer ring 22 of the second surround gear 21 and the rotation mode of the second center gear 23 are controlled, driving the rotation and revolution of the second surround gear 21, avoiding direct control of the surround gears through the tie rods, and preventing the tie rods of the upper surround gears from conflicting with the spatial positions of the lower surround gears.

[0065] In this embodiment, the rotation state of the first outer ring 12 is used to display minute information, and the rotation state of the second outer ring 22 gear is used to display hour information; the revolution state of the first surrounding gear 11 displays date information, and the revolution state of the second surrounding gear 21 displays month information. Specifically, the first outer ring 12 rotates at a speed of 1 rotation per hour, and the first central gear 13 rotates at a certain speed in the direction opposite to the rotation of the first outer ring 12 according to the relationship between the number of teeth of the first outer ring 12, the first central gear 13 and the first surrounding gear 11, so that the first surrounding gear 11 revolves around the first central gear 13 at a speed of 1 rotation per 31 days under the meshing action of the first central gear 13 and the first outer ring 12; the second outer ring 22 rotates at a speed of 30° per hour, and the second central gear 23 rotates at a certain speed in the direction opposite to the rotation of the second outer ring 22 according to the relationship between the number of teeth of the second outer ring 22, the second central gear 23 and the second surrounding gear 21, so that the second surrounding gear 21 revolves around the second central gear 23 at a speed of 1 rotation per 365.25 days under the meshing action of the second central gear 23 and the second outer ring 22.

[0066] Embodiment 5

[0067] See also Figure 5 In this embodiment, the dial structure includes a first outer ring 12, a first central gear 13 and a first surrounding gear 11. The first outer ring 12 and the first central gear 13 rotate around the same rotation axis. A first tooth structure 121 is provided on the inner side of the first outer ring 12. The first surrounding gear 11 is meshed with the first central gear 13 and the first tooth structure 121 at the same time. The first surrounding gear 11 can rotate around its own axis and revolve around the first central gear 13 at the same time. It also includes a second outer ring 22, a second central gear 23 and a second surrounding gear 21. The second outer ring 22 and the second central gear 23 rotate around the same two rotation axes.
