Abstract

A movement comprises a shell seat, a power mechanism, a time transmission mechanism and a week transmission mechanism. The time drive mechanism includes an hour hand drive unit having an hour hand shaft that rotates about a central axis. The week transmission mechanism comprises a week driving unit and a week adjusting button, wherein the week driving unit is provided with a clutch gear which is coaxially sleeved on the hour hand shaft rod with a resistance force, a week gear which rotates around the central axis, and a connecting gear set which is meshed with the week adjusting button, the clutch gear and the week gear. When the machine core needs to adjust the week, the connecting gear set and the week gear can be driven to rotate only by rotating the week adjusting button, and at the moment, the clutch gear idles around the hour hand shaft rod. Therefore, the clutch gear is convenient to adjust due to the design of the clutch gear anti-astringency binding sleeve.

Description

Movement

Technical Field

The invention relates to a mechanically-driven clock or watch, in particular to a movement capable of displaying time and week.

Background

Referring to fig. 1 and 2, a known movement 1 is disclosed in U.S. patent No. US8,526,272B2, and the known movement 1 includes a housing 11, a time gear 12, and a day gear 13. The housing 11 has a main housing 111, and the main housing 111 has a central hole 112.

The time transmission mechanism 12 includes a time gear unit 121 installed inside the housing 11, and a second hand 122, a minute hand 123, and an hour hand 124 driven to rotate by the time gear unit 121. The hour gear unit 121 has an hour hand gear 125 and an hour hand shaft 126 extending forward from the center of the hour hand gear 125 through the central hole 112 and coupled to the hour hand 124. Since how the time gear unit 121 drives the second hand 122, the minute hand 123 and the hour hand 124 to rotate is prior art and is not important for the improvement of the present invention, detailed description thereof is omitted.

The day gear mechanism 13 includes a day gear unit 131 mounted inside the case base 11, a day hand 132 driven to rotate by the day gear unit 131, and a day adjustment knob 14 rotatably mounted on the case base 11. The day gear unit 131 has a day gear 133 and a day shaft 134 that passes through the center of the day gear 133 forward through the center hole 112 and is linked with the day hand 132. The day adjustment knob 14 includes a link 141 axially movably mounted on the housing 11, a manipulating part 142 connected to the link 141 and protruding from the housing 11, an interlocking part 143 interlocking with the link 141 and engaging with the day gear 133 for transmission, and a clutch part 144 interlocking with the link 141 and engaging with or disengaging from the hour gear 125 due to axial displacement of the link 141.

When the known movement 1 is in a normal position as shown in fig. 1, the clutch part 144 of the day adjustment button 14 is engaged with the hour hand gear 125, and the time gear unit 121, in addition to driving the second hand 122, the minute hand 123 and the hour hand 124 to rotate, also drives the day gear unit 131 and the day hand 132 to rotate through the engagement of the hour hand gear 125 with the day adjustment button 14, thereby displaying the correct day.

When the week of the known movement 1 is to be adjusted, the week adjustment button 14 is pulled outward as shown in fig. 3, so that the clutch part 144 and the hour hand gear 125 can be driven to disengage from the detent, and at this time, the week adjustment button 14 is rotated, so that the week hand 132 can be driven to adjust to the correct position by the engagement of the interlocking part 143 and the week gear 133.

Although the known movement 1 has the effect of displaying the day, the day adjustment knob 14 needs to be moved between two positions in the axial direction thereof during adjustment of the day, and moreover, the adjustment operation is troublesome and inconvenient because the day adjustment knob 14 needs to be pulled to move axially and the day adjustment knob 14 needs to be rotated during adjustment.

It should be noted that the number of the engaging gears may also be increased or decreased, and is not limited to this embodiment.

The day adjustment knob 52 has a second rotary plate 521 which is disposed at the rear side of the rear cover 22 and has anti-slip insections, a second wheel column 522 which penetrates the rear cover 22 forward from the center of the second rotary plate 521, and a day adjustment gear 523 which is formed on the second wheel column 522 and can engage and drive the second engaging gear 572.

When the movement is in a power mode, the power mechanism 3 drives the seconds hand driving unit 41 to rotate the seconds hand 417, the seconds hand driving unit 41 drives the minute hand driving unit 42 to rotate the minute hand 423, the minute hand driving unit 42 drives the hour hand driving unit 43 to rotate the hour hand 433, during the rotation of the hour hand drive unit 43 about the central axis 45, since the toe portion 532 of the clutch gear 53 grips the surface of the hour hand shaft 432 toward the central axis 45, the clutch gear 53 also rotates with the hour hand shaft 432, and drives the first engaging gear 571 through engagement of the ring gear portion 531, the first engaging gear 571 engages with the day gear 54, and the day gear 54 drives the day hand 56 to rotate at a predetermined speed through the day shaft 55.

When the movement is in a time adjustment mode, the user can rotate the first rotating disc 441 of the time adjustment button 44 to engage and drive the fifth gear 424 through the time adjustment gear 443, and thus drive a series of engaged structures.

When the movement is in the one-week adjustment mode, the user can rotate the second dial 521 of the week adjustment button 52 only to engage the second engaging gear 572 through the week adjustment gear 523, engage the first engaging gear 571 through the second engaging gear 572, engage the clutch gear 53 again through the first engaging gear 571, but since the clutch gear 53 is tightly constrained around the hour hand shaft 432, the two are engaged only by the surface friction force, and the hour hand gear 431 and the series of structures engaged therewith are mechanically engaged, and the wheel train of the minute hand driving unit 42 and the second hand driving unit 41 has large reverse resistance and is not easy to rotate completely, in this case, the clutch gear 53 is bulky to overcome the surface friction force between the hour hand shaft 432, and is driven by the first engaging gear 571 to idle around the hour hand shaft 432, at the same time, the first engaging gear 571 also engages and drives the day gear 54, and the day hand 56 is driven by the day shaft rod 55 to rotate for adjusting the day.

To sum up, the movement of the present invention is sleeved on the periphery of the hour hand shaft 432 in a blocking manner through the clutch gear 53, and the week adjustment button 52 is externally added to the gear mechanism that the clutch gear 53 transmits to the week gear 54, when a user wants to adjust the week of the movement, the user only needs to rotate the week adjustment button 52 to transmit the clutch gear 53, and under the condition that the clutch gear 53 cannot drive the hour hand shaft 432, the user only needs to overcome the surface friction force between the clutch gear 53 and the hour hand shaft 432, so that the clutch gear 53 can idle by itself, and further the week gear 54 is transmitted through the first engaging gear 571 to adjust the position of the day hand 56, and in the adjustment process, the user only needs to rotate the week adjustment button 52, and does not need to pull out the axial displacement of pressing, so that the adjustment is simpler, Therefore, compared with the conventional movement 1 shown in fig. 1, the movement of the present invention has different technical means, technical principles and main technical features, and has better effects, so as to achieve the object of the present invention.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
