[0020] Referring to Figure 1 , Figure 2 and Figure 3 , the clock device comprises a base 1, a first movement unit 2 and a plurality of second movement units 31, 32, 33, 34 arranged on the base 1, a control circuit board 4 electrically connecting the first movement unit 2 and the second movement units 31, 32, 33, 34 through wires L, a toggle switch 5 electrically connected to the control circuit board 4, and a power unit 6 electrically connected to the control circuit board 4 through wires L.

[0021] The base 1 comprises a front disc surface 11 located at the front, and a seat back surface 12 located at the back. The front disc surface 11 comprises a date scale part 111 located at the top, a week scale part 112 located at the left, and a month scale part 113 located at the right.

[0022] The first movement unit 2 is arranged at the central part of the seat back surface 12, and comprises a casing module 21, a movement module 22 arranged in the casing module 21, a gear module 23 arranged in the casing module 21, a protruding block 24 arranged on the gear module 23, a trigger 25 arranged on the movement module 22, an adjusting knob 26 inserted in the casing module 21, and a hour hand 271, a minute hand 272 and a second hand 273 driven by the movement module 22 and the gear module 23.

[0023] The casing module 21 comprises a first casing 211 and a second casing 212. The first casing 211 and the second casing 212 cooperatively form a cuboid-shaped casing.

[0024] The movement module 22 comprises a movement plate 221 arranged between the first casing 211 and the second casing 212, and a pin core 222 inserted in the base plate and capable of driving the second hand 273.

[0025] The gear module 23 is mounted on the first casing 211 and is used to control the rotation of the hour hand 271 and the minute hand 272. The gear module 23 comprises a stacked hour gear 231 and a minute gear 232, and a gear shift 233 engaging the hour gear 231 and the minute gear 232. The hour gear 231 and the minute gear 232 are used to control the rotation of the hour hand 271 and the minute hand 272, respectively.

[0026] The protruding block 24 is triangular and integrally connected to the minute gear 232. The protruding block 24 protrudes along the axial direction of the minute gear 232.

[0027] The trigger 25 is electrically connected to the control circuit board 4 and comprises a trigger circuit 251 disposed on the machine board 221 of the movement module 22, and a trigger element 252 soldered to the trigger circuit 251 and electrically connected to the trigger circuit 251.

[0028] The trigger circuit 251 is electrically connected to the control circuit board 4 through the wire L. The trigger element 252 comprises two metal sheets 253. Each of the metal sheets 253 can be elastically deformed by the protruding block 24 on the minute gear 232 when the gear module 23 rotates, and can recover after deformation.

[0029] The adjustment knob 26 is inserted into the second casing 212 and comprises a knob portion 261 outside the second casing 212, and an engaging portion 262 integrally connected to the knob portion 261 and engaging the gear shift 233 of the gear module 23. The engaging portion 262 can rotate with the knob portion 261 when the knob portion 261 is driven, and drive the gear shift 233 to rotate. That is, rotating the adjustment knob 26 can drive the hour gear 231 and the minute gear 232, so as to adjust the positions of the hour hand 271 and the minute hand 272.

[0030] One of the second movement units 31 is used to display the moon phase and comprises a fixed disc 311 and a rotating disc 312 rotatable relative to the fixed disc 311.

[0031] The fixed disc 311 comprises a fixed shielding block 311a. The shielding block 311a comprises two large semi-circular portions 311b and a small semi-circular portion 311c between the large semi-circular portions 311b.

[0032] The rotating disc 312 is provided with a circular block 312a capable of moving relative to the shielding block 311a. The circular block 312a is used to simulate the moon. When the rotating disc 312 rotates, it can drive the circular block 312a to move relative to the shielding block 311a. The circular block 312a can be shielded or not shielded by the shielding block 311a to change between an incomplete circle or a complete circle, so the circular block 312a can be used to simulate the change of the moon's roundness. For example, when the circular block 312a is completely shielded by the shielding block 311a, it represents a new moon. When the circular block 312a is partially exposed and mostly shielded by one of the large semicircular parts 311b, it represents a crescent moon or a waning moon. When the circular block 312a is mostly exposed and partially shielded by one of the large semicircular parts 311b, it represents a waxing moon or a gibbous moon.

[0033] In addition, the second movement unit 32 includes a date hand 321 arranged at the date scale position 111. In addition, the second movement unit 33 includes a week hand 331 arranged at the week scale position 112. In addition, the second movement unit 34 includes a month hand 341 arranged at the month scale position 113.

[0034] Each of the second movement units 31, 32, 33, and 34 includes an adjusting wheel 35. The adjusting wheel 35 can be used by the user to adjust the moon phase, the date, the week, and the month, respectively.

[0035] The toggle switch 5 can be toggled and reset after being toggled for the user to toggle next time.

[0036] When the embodiment is used for the first time, the hour hand 271 and the minute hand 272 are first adjusted to a position about 0:30 by driving the gear module 23 through the adjusting knob 26 of the first movement unit 2. Then, after installing the battery, the time, the moon phase, the date, the week, and the month are adjusted to the exact time, the moon phase, the date, the week, and the month at the moment, respectively, by the adjusting knob 26 and the adjusting wheels 35 of the second movement units 31, 32, 33, and 34, that is, the setting is completed.

[0037] When the embodiment is in operation, the minute gear 232 of the gear module 23 will rotate with the passage of time. Since the minute gear 232 rotates one circle per hour, the minute gear 232 will rotate 24 circles per day. In the process of rotating the minute gear 232, the protruding block 24 will move with the rotation of the minute gear 232 and intermittently (specifically, once an hour) push the metal sheet 253 of the trigger element 252 in the process of moving.

[0038] Whenever the trigger element 252 is triggered once, the trigger circuit 251 will transmit a trigger signal to the control circuit board 4, so that the control circuit board 4 can control the second movement units 31, 32, 33, 34 according to the number of the trigger signals received.

[0039] Specifically, since the protruding block 24 rotates with the minute gear 232 every day, the protruding block 24 will trigger the trigger element 252 for 24 times a day, so that the control circuit board 4 will count up a day whenever it receives 24 trigger signals, that is, the corresponding second movement units 32, 33 are controlled to drive the date pointer 321 and the week pointer 331 to move one step, respectively, so as to make the date +1 or the week +1. In addition, assuming that a Gregorian month is 30 days, since 24*30=720, the corresponding second movement unit 34 can be controlled to drive the month pointer 341 to count up one month whenever the control circuit board 4 receives 720 trigger signals.

[0040] Since there may be a difference between large and small months, the date or month can be fine-tuned by pulling the pull switch 5 if necessary. The pull switch 5 can transmit a trigger signal to the control circuit board 4 once every time it is pulled, so that the user can make the date pointer 321 and the week pointer 331 advance one step by pulling 24 times. In other embodiments of the present application, the pull switch 5 can also be set to transmit 24 trigger signals to the control circuit board 4 every time it is pulled, so as to facilitate operation.

[0041] In other embodiments of the present application, if the protruding block 24 is arranged on the hour gear 231, since the hour gear 231 rotates for 12 hours, that is, the hour gear 231 rotates 2 times a day, the control circuit can also be set to make the date pointer 321 and the week pointer 331 count up one day every time it receives 2 trigger signals, and make the month pointer 341 count up one month every time it receives 60 trigger signals.

[0042] In summary, in the clock device of the present application, the protruding block 24 can intermittently trigger the trigger 25 to make the trigger 25 transmit a trigger signal to the control circuit board 4 during the process of driving the hour hand 271 and the minute hand 272 to swing. The control circuit board 4 can make a simple count-up processing according to the number of the trigger signals, thereby controlling the second movement units 31, 32, 33, 34. Since the present application only uses the control circuit board 4 which can make a simple count-up calculation, without using a central processing unit which can make complex operations, or in other words, the present application does not include a central processing unit, the present application has the characteristics of low production cost.

[0043] The above merely describes a specific implementation of the present application, and cannot limit the scope of the claims of the present application. Equivalent changes made in accordance with the claims and description of the present application should also be covered by the claims of the present application.
