Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals.

Referring to fig. 1, 2 and 3, a first embodiment of the lunar phase timing apparatus of the present invention is used for providing time and lunar phase information. The lunar phase timing device comprises a lunar phase indication module 2 and a movement mechanism 3 arranged at the rear side of the lunar phase indication module 2.

The lunar phase indication module 2 comprises a lunar phase plate 21 and an indication piece 22 arranged at the front side of the lunar phase plate 21, wherein in the first embodiment, the indication piece 22 is a pointer. The forward front face of the lunar phase plate 21 is provided with a lunar calendar indication area 23, a lunar phase indication area 24 and a time indication area 25 which are sequentially arranged radially outwards around a center line 4. The lunar calendar indication area 23 has a plurality of lunar dates 26 spaced around the centerline 4, the lunar phase indication area 24 has a plurality of lunar phase symbols 27 spaced around the centerline 4, and the time indication area 25 has a plurality of hour symbols 28 spaced around the centerline 4.

The movement mechanism 3 includes a chronograph unit 31, and a lunar phase movement unit 32 connected to the front side of the chronograph unit 31.

The timing unit 31 has a hollow housing 310, a timing movement 311 mounted in the housing 310 and protruding forward out of the housing 310 for timing, and a minute hand 314 and an hour hand 315 disposed on the timing movement 311. The timepiece movement 311 may be an existing mechanical timepiece structure or a quartz timepiece structure. The timepiece movement 311 has a minute hand rotating shaft 312 and an hour hand rotating shaft 313 which pass through the housing 310 and the lunar rover 21 forward along the central line 4, the minute hand 314 and the hour hand 315 are respectively installed on the minute hand rotating shaft 312 and the hour hand rotating shaft 313 in a driving manner and located at the front side of the lunar rover 21, and the hour hand 315 is used for indicating the hour symbol 28.

In the first embodiment, the hour hand rotating shaft 313 rotates once in 24 hours, and the time indication area 25 of the lunar disk 21 corresponds to 24 hours, but in other implementation aspects, the hour hand rotating shaft 313 can also rotate once in 12 hours, and the time indication area 25 corresponds to 12 hours. It should be noted that the timing unit 31 is driven by a series of gears to rotate the minute hand 314 and the hour hand 315 at different speeds, but the structure and principle of timing are the prior art and are not the main point of the present invention, so detailed description is omitted.

The lunar camera movement unit 32 has a cover 33 detachably covering the front side of the housing 310, and the cover 33 and the housing 310 cooperate to define an accommodating space 30. The cover 33 has a first protrusion 331 and a second protrusion 332 protruding into the receiving space 30, and a connection part 333 extending forward along the center line 4 and connected to the lunar phase indication module 2. The engagement portion 333 has an engagement hole 334 through which the minute hand rotating shaft 312 and the hour hand rotating shaft 313 pass forward.

The lunar phase movement unit 32 further has a transmission gear 34 coaxially sleeved on the hour hand rotation shaft 313 and synchronously driven to rotate by the hour hand rotation shaft 313, a speed change gear 35 disposed on the first convex column portion 331 and meshed with the transmission gear 34 for transmission, a lunar phase gear 36 rotatably sleeved outside the hour hand rotation shaft 313 and meshed with the speed change gear 35 for transmission, a lunar phase rotation shaft 37 connected to the lunar phase gear 36 and passing through the connection hole 334 and the lunar phase plate 21 forward along the center line 4 and capable of driving the indication member 22 to rotate, and a lunar phase adjustment button 39 disposed on the second convex column portion 332 and meshed with the speed change gear 35 and capable of being driven to rotate and drive the speed change gear 35 to rotate. The transmission gear 35 has a large gear portion 351 engaged with the transmission gear 34 and the lunar phase adjustment knob 39, and a small gear portion 352 coaxially disposed at a front side of the large gear portion 351 and engaged with the lunar phase gear 36.

Referring to fig. 2, 3 and 4, the transmission gear 34 has an annular tooth portion 341 engaged with the large gear portion 351, and a plurality of elastic portions 342 disposed at the inner periphery of the annular tooth portion 341 in an equiangular distribution and cooperating with the hour hand rotating shaft 313 to elastically press against the hour hand rotating shaft 313, and the elastic portions 342 together define a tightening hole 345 for the hour hand rotating shaft 313 to pass through in an obstructing manner. Each of the elastic portions 342 has a connecting section 344 extending from the inner periphery of the annular tooth portion 341, and two abutting arms 343 extending from the connecting section 344 outward around the center line 4 in an arc shape and spaced from the annular tooth portion 341, and the elastic portions 342 elastically abut against the outer periphery of the hour hand rotating shaft 313 via the abutting arms 343.

It should be noted that, since the transmission gear 34 is sleeved on the hour hand rotating shaft 313 by the abutting force generated by the abutting arm 343 elastically abutting against the outer peripheral surface of the hour hand rotating shaft 313, the transmission gear can be synchronously driven to rotate by the rotation of the hour hand rotating shaft 313. However, since the time counting unit 31 is a large gear transmission structure, the hour hand rotating shaft 313 can only be driven by the movement structure in the housing 310, and cannot be directly driven by external force. Therefore, when the lunar phase adjustment button 39 is driven to rotate the transmission gear 34, the tightening force applied by the transmission gear 34 to the hour hand rotating shaft 313 cannot drive the hour hand rotating shaft 313 to rotate synchronously, so that the transmission gear 34 rotates relative to the hour hand rotating shaft 313.

In addition, in the first embodiment, it takes 29.5 days for the lunar phase rotation shaft 37 to rotate for 1 turn, and it takes 1 day for the hour hand rotation shaft 313 to rotate for 1 turn, so the goal of slowing the rotation speed of the lunar phase rotation shaft 37 than the hour hand rotation shaft 313 is achieved by the design that the transmission gear 34 of the lunar phase movement unit 32, the large gear portion 351 of the transmission gear 35, the small gear portion 352 of the transmission gear 35 and the lunar phase gear 36 have different numbers of teeth. In detail, the number of teeth of the transmission gear 34 is less than that of the large gear portion 351 of the transmission gear 35, the number of teeth of the small gear portion 352 is less than that of the large gear portion 351, and the numbers of teeth of the large gear portion 351 and the small gear portion 352 are both less than that of the lunar gear 36.

The utility model discloses when the moon phase timing device used, when this timing unit 31 started the timing function, can be via driving this minute hand 314 and this hour hand 315 of commentaries on classics in order to carry out time indication. In the process of the rotation of the hour hand rotating shaft 313, the hour hand rotating shaft 313 drives the transmission gear 34 to rotate synchronously, the transmission gear 34 drives the lunar phase gear 36 to rotate through the speed changing gear 35, so that the lunar phase rotating shaft 37 fixed on the lunar phase gear 36 drives the indicating member 22 to rotate, for indicating the lunar calendar indicating area 23 and the lunar phase indicating area 24.

When the indicator 22 is to be adjusted, the user can operate the moon phase adjusting button 39 to rotate the transmission gear 35, so that the pinion portion 352 of the transmission gear 35 rotates the moon phase gear 36 to rotate the moon phase rotating shaft 37 and the indicator 22. Meanwhile, the large gear portion 351 of the speed changing gear 35 synchronously drives the transmission gear 34 to rotate the transmission gear 34 relative to the hour hand rotating shaft 313, so that the lunar phase adjustment knob 39 can be used for independently adjusting and rotating the indicating member 22 without rotating the minute hand 314 and the hour hand 315.

It should be noted that, in the first embodiment, the transmission gear 35 is designed to generate two-stage speed change through the large gear portion 351 and the small gear portion 352, so that the lunar phase rotation shaft 37 rotates for 1 circle for 29.5 days, but in other embodiments of the present invention, the transmission gear 35 may be designed to generate one-stage speed change only through one large gear portion 351, as long as the lunar phase rotation shaft 37 can rotate for 1 circle for 29.5 days, and the invention is not limited to the manner described in the first embodiment.

Furthermore, in the first embodiment, the lunar phase rotation axis 37 and the hour hand rotation axis 313 are coaxially disposed on the center line 4, and the lunar calendar date 26, the lunar phase symbol 27, and the hour symbol 28 are also distributed around the center line 4, but in other embodiments of the present invention, the lunar phase rotation axis 37 may not be coaxial with the hour hand rotation axis 313, and the lunar calendar date 26 and the lunar phase symbol 27 distributed around the lunar phase rotation axis 37 and the hour symbol 28 distributed around the hour hand rotation axis 313 may be disposed on the lunar phase plate 21.

Referring to fig. 5, the second embodiment of the lunar phase timing device of the present invention is substantially the same as the components of the first embodiment, except that: the structure of the lunar phase indicating module 2 and the connection mode of the lunar phase indicating module 2 and the movement mechanism 3. For convenience of explanation, only differences between the embodiments will be described below.

In the second embodiment, the lunar phase indicating module 2 includes a lunar phase plate 21 facing forward and coupled to the lunar phase rotation shaft 37, and an indicating member 22 disposed at a front side of the lunar phase plate 21 and coupled to the coupling part 333. The front surface of the lunar phase plate 21 is provided with a lunar calendar indication area 23 and a lunar phase indication area 24 which are sequentially arranged radially outwards around a central line 4. The lunar calendar indication area 23 has a plurality of lunar dates 26 spaced around the centerline 4, and the lunar phase indication area 24 has a plurality of lunar phase symbols 27 spaced around the centerline 4. The indicator 22 is a plate covering the front side of the lunar phase plate 21 and connected with the connecting part 333, and a viewing window 29 for corresponding to the lunar calendar date 26 and the lunar phase symbol 27 is arranged in front and back. The indicator 22 is also provided with a time indicator zone 25 on the front side thereof surrounding the centre line 4, the time indicator zone 25 having a plurality of hour symbols 28 spaced around the centre line 4.

When the movement mechanism 3 is started, the lunar phase rotating shaft 37 will drive the lunar phase plate 21 to rotate relative to the indicating piece 22, so that the lunar phase symbols 27 sequentially pass through the viewing window 29 to indicate lunar phases.

In summary, the lunar phase indicating module 2 is connected to the lunar phase rotating shaft 37 and can be driven by the lunar phase rotating shaft 37 to operate, and the lunar phase disk 21 provided with the lunar calendar date 26 and the lunar phase symbol 27 is matched with the design that the transmission gear 34 of the lunar phase movement unit 32, the large gear portion 351 of the transmission gear 35, the small gear portion 352 of the transmission gear 35 and the lunar phase gear 36 have different numbers of teeth, so that the lunar phase rotating shaft 37 can drive the lunar phase disk 21 and the indicating member 22 to rotate relatively to provide lunar phase information. In addition, the design that the abutting arm 343 of the transmission gear 34 abuts against the outer peripheral surface of the hour hand rotating shaft 313 makes the minute hand 314 and the hour hand 315 not to rotate during adjustment of the indicator 22, which is a quite innovative and practical creation, so that the purpose of the utility model can be achieved.

However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereto, and all the simple equivalent changes and modifications made according to the claims and the contents of the specification should be included in the scope of the present invention.
