[0040] Example 1

[0041] like Figure 1-10 As shown, a non-circular trajectory minute hand reading mechanism includes a display component and a transmission component. The transmission component transmits power to the display component, and the display component indicates the time.

[0042] The display components include a non-circular track ring 110, an hour hand indicator cover 120, an hour hand indicator 130, a minute hand component 140, and a sway component 150; the transmission components include an output shaft 211 located at the center of the dial.

[0043] The hour hand indicator 130, the hour hand indicator cover 120, the minute hand 140, and the non-circular track ring 110 are sequentially sleeved on the output shaft 211 from bottom to top. The hour hand indicator 130 is provided with scale values ​​for indicating time at equal intervals in the circumference. The hour hand indicator cover 120 has at least one opening 121, which exposes the scale values.

[0044] One end of the ornament 150 is attached to one end of the dial needle 140, and the other end of the ornament 150 abuts against the inner ring of the non-circular track ring 110. The ornament 150 moves along the inner ring of the non-circular track ring 110.

[0045] Specifically, such as Figure 1 As shown, the transmission component drives the minute hand 140 to rotate, which in turn moves the oscillating element 150 within the inner ring of the non-circular track ring 110, thus indicating the minute reading. The transmission component also drives the hour hand indicator 130 to rotate, thereby displaying the hour reading at the opening position 121. This non-circular track minute hand reading mechanism and watch, through the design of the transmission component to transmit power, allows the minute hand, although rotating centrally, to exhibit a non-circular movement path in conjunction with the oscillating element 150 and the non-circular track ring 110. This design allows users to choose according to different preferences, enhancing the watch's aesthetic appeal.

[0046] In this embodiment, as Figure 2 and 3As shown, the transmission assembly includes a pointer power assembly 210, which is located above the hour hand indicator cover 120. The pointer power assembly 210 includes a first gear 212, a second gear 213, a third gear 214, a first shaft 215, and several bearings 216. The first gear 212 is connected to the output shaft 211 through the bearings 216. The first gear 212 is connected to the second gear 213. The second gear 213 is connected to the third gear 214. The first shaft 215 connects the oscillating member 150, the minute hand member 140, and the third gear 214 in sequence. The minute hand member 140 is connected to the first shaft 215 by a bearing 216.

[0047] Specifically, power is transmitted from the movement 300 to the output shaft 211, driving the minute hand component 140 to rotate. Since the first shaft 215 connects the minute hand component 140 and the third gear 214, as well as the first gear 212, the second gear 213 and the gear, the minute hand component 140 rotates, causing the third gear 214 to rotate around the axis of the output shaft 211. Furthermore, the first shaft 215 connects the minute hand component 140 and the swing component 150, so the swing component 150 follows the minute hand component 140 to rotate, and its adaptive position moves around the non-circular track ring 110.

[0048] In this embodiment, as Figure 4-6 As shown, the transmission assembly includes an indicator disk power assembly 220, which is located below the hour hand indicator disk cover 120. The indicator disk power assembly 220 includes a turn wheel 221, a fourth gear 222, a fifth gear 223, a sixth gear 224, a first actuation component 225, and a second actuation component 226. The fifth gear 223 is a double-layered gear. The turn wheel 221 is sleeved inside the output shaft 211, and the fourth gear 222 is sleeved outside the turn wheel 221. The fourth gear 222 is fixedly connected to the hour hand indicator disk 130. The fifth gear 223 and the sixth gear 224 are coaxially fixedly connected. One layer of teeth of the fifth gear 223 meshes with the turn wheel 221, and the sixth gear 224 meshes with the fourth gear 222. The fourth gear 222 is connected to the first actuation component 225, and the other layer of teeth of the fifth gear 223 is connected to the second actuation component 226.

[0049] Specifically, power is transmitted to the actuation wheel 221 through the output shaft 211. When the actuation wheel 221 rotates once, it actuates one tooth of the fifth gear 223. Since the fifth gear 223 and the sixth gear 224 are coaxially fixedly connected, the sixth gear 224 actuates the fourth gear 222 to rotate one tooth. Since the fourth gear 222 is fixedly connected to the hour hand indicator 130, the hour reading jumps one division.

[0050] Specifically, the first actuation component 225 and the second actuation component 226 are each provided with a locking position. When the actuation wheel 221 rotates one revolution, the jump time function is triggered, that is, the fourth gear 222 or the fifth gear 223 rotates one tooth, and the paddle pops out and returns to the locking position, preventing the fourth gear 222 or the fifth gear 223 from rotating continuously. Therefore, the first actuation component 225 and the second actuation component 226 make the hour reading appear to jump, rather than the hour hand indicator 130 rotating slowly.

[0051] In this embodiment, the opening 121 is located at the 6 o'clock position on the dial. Specifically, according to viewing habits, the displayed reading is located below the dial. If the non-circular track ring 110 obstructs the opening 121, a groove needs to be made in the non-circular track ring 110 to accommodate it. In other embodiments, the opening 121 can be placed at any position on the dial.

[0052] In this embodiment, a second hand component 160 is also included, which is connected to the transmission assembly. Specifically, the user can choose whether to equip the component with a second hand based on their usage habits. The second hand shaft is sleeved inside the output shaft 211, and the second hand component 160 is connected to and positioned around the second hand shaft.

[0053] In this embodiment, adjusting the size of the ornament 150 and the gear structure in the pointer power assembly 210 allows the ornament 150 to move along the non-circular trajectory ring 110. Therefore, to accommodate different preferences, the non-circular trajectory ring 110 can be designed in various shapes, for example:

[0054] like Figure 7 As shown, the non-circular trajectory loop 110 is a loop consisting of four identical circular arcs connected together, with the center of each arc located on the outside of the loop.

[0055] like Figure 8 As shown, the non-circular trajectory loop 110 is a loop consisting of four identical circular arcs connected together, with the center of each arc inside the loop.

[0056] like Figure 9 As shown, the non-circular trajectory loop 110 is a loop connected by three identical circular arcs, with the center of the arcs on the outside of the loop.

[0057] like Figure 10 As shown, the non-circular trajectory loop 110 is a loop formed by two semicircles connected to form a figure-eight shape.

[0058] Example 2

[0059] A watch includes a movement 300, a positioning mechanism 400, and a non-circular trajectory minute hand reading mechanism of any one of the above, wherein the positioning mechanism 400 connects the movement 300 and the non-circular trajectory minute hand reading mechanism.

[0060] Since a non-circular trajectory minute hand reading mechanism has the above-mentioned technical effects, watches including non-circular trajectory minute hand reading mechanisms should also have the corresponding technical effects, which will not be elaborated here.

[0061] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0062] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
