Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those generally understood by those skilled in the art of the present invention. The terms used herein in the description of the present invention are for the purpose of describing particular examples only and are not intended to limit the present invention. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

FIGS. 1 to 10 schematically show a structure of a timepiece according to an embodiment of the present invention.

A timepiece, including a movement, the movement including an outer barrel 1, an inner roller 2, a driving device 3 and a lead screw structure 4. In addition, the timepiece may further include a watch housing 7 and a watch band 8, but is not limited thereto.

As shown in FIGS. 2 and 3, the inner roller 2 can be mounted in the outer barrel 1, and the driving device 3 can drive the outer barrel 1 and the inner roller 2 to rotate in opposite directions and at different rotational speeds, so that different numbers on the inner roller 2 can coincide with windows 11 of the outer barrel 1 at different times. As numbers are provided on the inner roller 2, only the number corresponding to the window 11 is displayed at the same time, a certain time can be displayed by numbers, and in addition, the lead screw 42 is located below the outer barrel 1 and the inner roller 2, and the lead screw structure 4 can also be used to indicate time.

The described outer barrel 1 and inner roller 2 can display “hour” and “minute”, and the screw rod 42 can indicate “minute” and “second”. A specific display manner is described later.

In this example, as shown in FIG. 5 to FIG. 7, the driving device 3 includes a first driving motor 31 and a gear reducer set 32. The first driving motor 31 is connected to the gear reducer set 32, the first driving motor 31 can drive the gear reducer set 32 to move, and the gear reducer set 32 can drive the outer barrel 1 and the inner roller 2 to rotate in opposite directions and at different rotation speeds. By the same driving motor and the transmission ratio of the gear reducer set 32 and the outer barrel 1 and the inner roller 2, different numbers on the inner roller 2 coincide with the windows 11 on the outer barrel 1 at different times, and the numbers corresponding to the windows 11 are displayed, thereby achieving the purpose of displaying time.

The specific structure of the gear reducer set 32 will be described in detail below. In this example, the gear reducer set 32 includes a first transmission gear 321, a second transmission gear 322, a third transmission gear 323 and a fourth transmission gear 324, the first transmission gear 321 is connected to the first driving motor 31, and the second transmission gear 322, the third transmission gear 323 and the fourth transmission gear 324 are in sequential transmission. In fact, the second transmission gear 322 includes a large gear and a small gear, and the large gear is fitted with the first transmission gear 321, and the inner small gear is fitted with the third transmission gear 323.

In addition, it can be determined from FIG. 5 and FIG. 7 that a fifth transmission gear 325 is coaxially connected to the inner roller 2, a sixth transmission gear 326 is coaxially connected to the outer barrel 1, and the third transmission gear 323 is fitted with the fifth transmission gear 325, the fourth transmission gear 324 is fitted with the sixth transmission gear 326. It can be determined from FIG. 5 and FIG. 7 that when the third transmission gear 323 rotates, the fourth transmission gear 324 can be driven to rotate, the fifth transmission gear 325 can also be driven to rotate at the same time, the rotation direction of the fifth transmission gear 325 is opposite to the rotation direction of the third transmission gear 323, the fourth transmission gear 324 can drive the sixth transmission gear 326 to rotate, the rotation direction of the sixth transmission gear 326 is the same as the rotation direction of the third transmission gear 323, and as the tip diameter of the sixth transmission gear 326 is larger than that of the fifth transmission gear 325, the rotation speed of the sixth transmission gear 326 may be less than that of the fifth transmission gear 325, and the rotation directions of the sixth transmission gear 326 and the fifth transmission gear 325 are opposite.

Therefore, by the specific arrangement of the described transmission gear set, the transmission ratio of the third transmission gear 323 and the fifth transmission gear 325, and the transmission ratio of the fourth transmission gear 324 and the sixth transmission gear 326 cause the outer barrel 1 and the inner roller 2 to rotate at different rotation speeds in opposite directions. By the gear reducer set 32 having such a specific structure, i.e. setting the transmission ratio of the third transmission gear 323 and the fifth transmission gear 325, and the transmission ratio of the fourth transmission gear 324 and the sixth transmission gear 326, so as to achieve the purpose that different numbers coincide with the windows 11 of the outer barrel 1 at different times. The current time is displayed by numbers.

In addition, in other examples, the structure of the gear reducer set 32 is not limited to the described manner, and may also be a structure composed of a plurality of other gears. Regardless of the form of the gear reducer set 32, as long as the final purpose of the gear reducer set 32 is to rotate the inner roller 2 and the outer barrel 1 in opposite directions and at different speeds, so as to finally present the numbers, i.e. display the time corresponding to the numbers, it is within the scope of protection of the present application. In addition, a person skilled in the art should know that the quantity of gears in the gear reducer set 32 and a corresponding transmission ratio can be set according to practical situations.

In this example, as shown in FIG. 7, the inner roller 2 includes a rotating rod 21 and a plurality of rotating wheels 22 marked with numbers, the plurality of rotating wheels 22 are provided on the rotating rod 21 at intervals, the plurality of groups of rotating wheels 22 are integrally formed with numbers, and the numbers on the plurality of rotating wheels 22 are different and there are twelve numbers in total.

There are n rotating wheels 22, and 12/n numbers are provided on the outer circumference of each of the rotating wheels 22, wherein n and 12/n are integers and greater than or equal to 2, the quantity of the numbers on the plurality of rotating wheels 22 is equal, a difference value between two adjacent numbers on each rotating wheel 22 is equal, and in an extending direction of the rotating rod 21, the value of the corresponding numbers on the first to nth rotating wheels gradually increases or decreases. The rotation angle of two adjacent numbers on each of the rotating wheels is 360°/n. The rotation angle of the numbers at the corresponding positions of two adjacent rotating wheels is 30°.

In this example, the value of n is 4, there are four rotating wheels 22, and the outer circumference of each rotating wheel 22 is provided with three numbers. Specifically, as shown in FIG. 7, each turning wheel 22 is provided with three arc-shaped sheets 221, each arc-shaped sheet 221 is marked with numbers, in the direction from left to right of the rotating rod 21, the numbers “1, 5, 9” are marked on the first rotating wheel 22, the numbers “2, 6, 10” are marked on the second rotating wheel 22, the numbers “3, 7, 11” are marked on the third rotating wheel 22, the numbers “4, 8, 12” are marked on the fourth rotating wheel 22, the rotation angle of two adjacent arc-shaped sheets 221 on each of the rotating wheels 22 is 120°, and in addition, the rotation angle of the arc-shaped sheets 221 at the corresponding positions of the two adjacent rotating wheels 22 is 30°, that is, as shown in FIG. 7, the rotation angle between the arc-shaped sheet 221 marked with the number “5” and the arc-shaped sheet 221 marked with the number “10” is 30°.

As will be described in detail hereinafter, on the first rotating wheel 22 from left, the rotation angle between the arc-shaped sheet 221 marked with the number “9” and the arc-shaped sheet 221 marked with the number “5” is 120°, the rotation angle between the arc-shaped sheet 221 marked with the number “5” and the arc-shaped sheet 221 marked with the number “1” is 120°, and the rotation angle between the arc-shaped sheet 221 marked with the number “1” and the arc-shaped sheet 221 marked with the number “9” is 120°. The described rotation angle refers to an angle of clockwise rotation of the inner roller 2 when viewed from left to right. By the same reasoning, the rotation angles of the numerals on the second rotating wheel 22, the third rotating wheel 22, and the fourth rotating wheel 22 can be deduced.

In FIG. 7, the rotation angle between the arc-shaped sheet 221 marked with the number “5” and the arc-shaped sheet 221 marked with the number “10” is 30°, and it can be determined that the rotation angle between the arc-shaped sheet 221 marked with the number “9” and the arc-shaped sheet 221 marked with the number “5” is 120°; therefore, the rotation angle between the arc-shaped sheet 221 marked with the number “9” and the arc-shaped sheet 221 marked with the number “10” is 150°. By the same reasoning, it can be deduced that the rotation angle between the arc-shaped sheets 221 marked with two adjacent numbers is 150°, for example, the rotation angle between the arc-shaped sheet 221 marked with the number “1” and the arc-shaped sheet 221 marked with the number “2” is 150°. The described rotation angle refers to an angle of clockwise rotation of the inner roller 2 when viewed from left to right.

That is, the roller 2 is rotated by 150° at every time interval, i.e. from number “1” to number “2”. The twelve numbers can be allocated to four groups of rotating wheels 22, the numbers allocated to the four groups of rotating wheels 22 are more reasonable, and the sizes of the numbers can also be adapted to actual use, so that a good state of time display can be achieved.

In other examples, the quantity of rotating wheels 22 may also be three, two, six, or the like. In addition, when there are three rotating wheels 22, four numbers may be marked on each of the rotating wheels 22, and when there are two rotating wheels 22, six numbers may be marked on each of the rotating wheels 22. The quantity of rotating wheels 22 can be designed according to actual needs, and the design of each number on the rotating wheels 22 and the design of the angle of the arc-shaped sheet 221 can be correspondingly changed according to the described content.

For example, when there are three rotating wheels 22, each rotating wheel 22 is provided with four arc-shaped sheets 221, each arc-shaped sheet 221 is marked with numbers, in the direction from left to right of the rotating rod 21, the numbers “1, 4, 7, 10” are marked on the first rotating wheel, the numbers “2, 5, 8, 11” are marked on the second rotating wheel 22, the numbers “3, 6, 9, 12” are marked on the third rotating wheel 22, the rotation angle of two adjacent numbers on each of the rotating wheels 22 is 90°, and the rotation angle of the numbers at the corresponding positions of two adjacent rotating wheels 22 is 30°.

For example, when there are two rotating wheels 22, each rotating wheel 22 is provided with six arc-shaped sheets 221, and each arc-shaped sheet 221 is marked with numbers, in the direction from left to right of the rotating rod 21, the numbers “1, 3, 5, 7, 9, 11” are marked on the first rotating wheel, the numbers “2, 4, 6, 8, 10, 12” are marked on the second rotating wheel, the rotation angle of two adjacent numbers on each of the rotating wheels 22 is 60°, and the rotation angle of the numbers at the corresponding positions of two adjacent rotating wheels is 30°.

In this example, each of the rotating wheels 22 is of a round wheel-shaped structure as a whole, and the rotating wheels 22 of this structure can cooperate with the rotating rod 21.

Please refer to FIGS. 9 and 10, in this example, the inner roller 2 further includes positioning screws 24, the rotating wheels 22 are provided with screw holes, the corresponding positions of the rotating rod 21 are also provided with positioning holes 211, and the positioning screws 24 pass through the screw holes and are provided in the positioning holes 211, the rotating wheels 22 can be fixed on the rotating rod 21 by the positioning screws 24, and the rotating wheels 22 can rotate together with the rotating rod 21.

In this example, the inner roller 20 is made of aluminum alloy.

In this example, the timepiece further includes a frame 5, the outer barrel 1, the inner roller 2, the driving device 3 and the lead screw structure 4 can all be mounted on the frame 5, the outer barrel 1 is of a hollow structure, four windows 11 are integrally formed at corresponding positions of the outer barrel 1, and the rotation angle between two adjacent windows 11 is 90°. At a certain time, the numbers on the rotating wheels 22 are correspondingly displayed by the windows 11 of the outer barrel 1, and only one number is displayed in each window 11.

In fact, most part of the structure of the outer barrel 1 serves to block the numbers on the inner roller 2, so that the windows 11 coincide with the numbers on the inner roller 2 at the same time, only one number is displayed corresponding to each window 11, and the number displayed in the window 11 represents the current time. In other example, the structure of the frame 5 is not limited to that shown in FIG. 1 to FIG. 4, as long as the frame 5 can be used for fixedly mounting the outer barrel 1, the inner roller 2, the driving device 3 and the lead screw structure 4. One of the numbers of the inner roller 2 may be displayed by a corresponding window 11 of the outer barrel 1.

Hereinafter, the time display mode of the present invention will be described in detail with reference to the solution that there are four rotating wheels 22 on the inner roller 2, i.e. there are four rotating wheels 22 and four windows 11, at a certain time, the numbers on the four rotating wheels 22 of the inner roller 2 coincide with the windows 11 of the outer barrel 1. However, only one number is displayed by a corresponding window 11 of the outer barrel 1. Specifically, when the user wears the timepiece of the present invention, when raising the wrist, the displayed number can be seen under normal conditions of eyes (usually when looking at the watch in a front direction) (of course, the display described here is different from the display of the electronic watch, and it is the physical numbers on the inner roller 2 that are displayed), and other three numbers coinciding with the windows 11 are blocked by the frame 1.

Of course, if the other three numbers are not blocked by the frame 1, in use, the numbers in front of a person's eyes may be considered as displayed numbers, that is, one of the numbers of the inner roller 2 is displayed by a corresponding window 11 of the outer barrel 1, and the other numbers which are not in front of the person's eyes may be considered as numbers which are not displayed.

In this example, the present invention further includes a light reflection sensor 6, an end of the outer barrel 1 is provided with a light-blocking end cover 12, a round hole 121 is integrally formed on the light-blocking end cover 12, a light-blocking sheet 23 is mounted at an end of the inner roller 2, a U-shaped notch 231 is mounted on the light-blocking sheet 23, the light reflection sensor 6 can receive light reflected by itself, and the zeroing effect can be achieved by the light reflection sensor 6, so as to achieve different functions.

Specifically, zeroing is performed as follows: when the light emitted by the light reflection sensor 6 successively passes through the round hole 121 on the light-blocking end cover 12 and the U-shaped notch 231 on the light-blocking sheet 23, the light is not reflected back, and at this time, zeroing is performed, that is, as shown in FIG. 2, the number “12” coincides with the corresponding window 11 (zero point). On the contrary, when the light emitted by the light reflection sensor 6 does not pass through the round hole 121 on the light-blocking end cover 12 and the U-shaped notch 231 on the light-blocking sheet 23, the light is reflected back, and zeroing is not performed at this time. Zeroing is primarily used to regulate different functions of the present invention.

In this example, as shown in FIG. 2 and FIG. 3, the lead screw structure 4 includes a second driving motor 41, a lead screw 42 and a pointer nut 43, the pointer nut 43 is sleeved on the lead screw 42, and the second driving motor 41 can drive the lead screw 42 to rotate. Definitely, a speed reduction gear is also provided between the motor and the lead screw 42, the lead screw 42 drives the pointer nut 43 to move, the motor can be reversed, and the pointer nut 43 can indicate time, finally, the pointer nut 43 can be driven to move by the second driving motor 41, and when the pointer nut 43 moves to different positions, different times may be indicated.

As shown in FIG. 2 and FIG. 3, a time indication scale 51 is provided on the frame 5, numbers are marked on the corresponding scale, and the current time can be clearly displayed by the indication scale 51.

As shown in FIG. 1, a frame 5 is mounted in a watch housing 7, the watch housing 7 can cover a movement, a watch band 8 is further provided on the watch housing, and the watch housing 7 has the function of covering the movement and protecting the movement.

The overall different functions of the present invention are described in detail as follows: 1. a conventional timekeeping function, for example, when the current time is “1” o'clock, that is, the arc-shaped sheet 221 marked with the number “1” coincides with the first window 11 from left of the outer barrel 1, and the user can see the number “1”. After one hour, the first driving motor 31 is started, and the first driving motor 31 finally drives the inner roller 2 to rotate 150° clockwise, at the same time, the outer barrel 1 rotates anticlockwise by 90°, and at this time, the arc-shaped sheet 221 marked with the number “2” coincides with the second window 11 from left of the outer barrel 1. The described inner roller 2 and outer barrel 1 achieve the function of displaying “hour” (number “1” is displayed at each time when the current time is 1 o'clock to 2 o'clock, number “2” is displayed at each time when the current time is 2 o'clock to 3 o'clock, and so on)

The pointer nut 43 on the lead screw structure 4 has the function of correspondingly indicating “minute”, equivalent to the function of displaying “minute” of time.

2. Zeroing of the timekeeping function: after pressing a zeroing button, the outer barrel 1 and the inner roller 2 rotate at the same time, after rotating a certain angle, when the light emitted by the light reflection sensor 6 passes through the round hole 121 on the light-blocking end cover 12 and the U-shaped notch 231 on the light-blocking sheet 23 in sequence, the light is not reflected back, and at this time, zeroing is performed, and the fourth window 11 from left of the outer barrel 1 coincides with number “12” marked on the arc-shaped sheet, so as to indicate (zero point).

3. A timing function: the crown 9 is continuously pressed three times within two seconds to start the timing function, and the motor drives the pointer nut 43 of the lead screw structure 4 to quickly move to the left-most zero point of the time indication scale 51, the outer barrel 1 and the inner roller 2 rotate at the same time, and when the outer barrel 1 and the inner roller 2 rotate by a certain angle, the light emitted by the light reflection sensor 6 passes through the round hole 121 on the light-blocking end cover 12 and the U-shaped notch 231 on the light-blocking sheet 23 in sequence, the light is not reflected back, and at this time, zeroing is performed, the fourth window 11 from left of the outer barrel 1 coincides with number “12” marked on the arc-shaped sheet to display the number, the crown 9 is then pressed once more to start timing, and the pointer nut 43 on the lead screw structure 4 correspondingly runs in the form of “second”. When the pointer nut 43 rapidly returns to the zero point of the time indication scale 51 when it runs 60 seconds, the outer barrel 1 and the inner roller 2 rotate simultaneously, and the arc-shaped sheet 221 marked with number “1” coincides with the first window 11 from left of the outer barrel 1 to display the number, equivalent to timing for 1 minute; with this accumulation, the crown 9 is pressed once again to stop the timing, and at this time, the number reading displayed in the window 11 on the outer barrel 1 is taken as minute, then the corresponding scale of the pointer nut 43 on the lead screw structure 4 indicates that the reading there of is second, and the sum of the timed minute and second is equal to the timed duration, for example, if the number reading displayed in the window 11 on the outer barrel 1 is “8”, and the corresponding scale of the pointer nut 43 indicate that the reading is “10”, then the timed duration is 8 minutes and 10 seconds.

The process of operating the functions of the present invention can also be made as follows by setting:

• • continuously pressing the crown for four times in 2 seconds to enter a time calibration mode;
  • continuously pressing the crown for three times in 2 seconds to enter a timing function mode;
