Among them, the starting mechanism and the time-telling mechanism are set correspondingly. The starting mechanism can move between the initial position and at least one time-telling start position. When the starting mechanism moves from the time-telling start position to the initial position, it can drive the time-telling mechanism to tell the time.

Further, the driving mechanism and the starting mechanism are arranged correspondingly, and the driving mechanism has a driving state and a separated state. When the driving mechanism is in the driving state, the driving mechanism and the starting mechanism are connected to each other. The driving mechanism can drive the starting mechanism to move from the time starting position to the initial position, and Maintain in the initial position; when the driving mechanism is in the separated state, the driving mechanism and the starting mechanism are separated from each other, and the starting mechanism moves from the initial position to the time starting position;

Further, the stop mechanism and the starting mechanism are arranged correspondingly, and the stop mechanism has a limiting state and a separated state. When the stopping mechanism is in the limiting state, the stopping mechanism conflicts with the starting mechanism to limit the direction of the starting mechanism towards the time starting position. Move; when the stop mechanism is in the separated state, the stop mechanism and the starting mechanism are separated from each other to release the restriction on the starting mechanism;

Further, the control mechanism is respectively provided corresponding to the driving mechanism, the stop mechanism and the starting mechanism. When the starting mechanism is in the initial position, the control mechanism can control the driving mechanism and the stopping mechanism to be in a separated state, and control the starting mechanism to move to the corresponding time start. position; when the starting mechanism is in the time-telling start position, the driving mechanism is in the driving state and the stop mechanism is in the limit state. The driving mechanism drives the starting mechanism to move from the time-telling start position to the initial position, and the starting mechanism drives the time-telling mechanism to strike the time.

Specifically, as shown in Figure 1-3, the starting mechanism includes a starting plate 100. The starting plate 100 is connected to a driving mechanism. The driving mechanism continues to provide reset power for the starting plate 100, that is, the driving mechanism can drive the starting mechanism from the time starting position to the starting position. The initial position is moved. The initial position of the start plate 100 is provided with a third limiting component, that is, the first eccentric nail 291 shown in the figure. The driving mechanism pushes the start plate 100 to abut the first eccentric nail 291, so that the start plate 100 remains Stay in the initial position.

The driving mechanism corresponds to the second end of the second transmission member 140 in the transmission unit described below. When the start dial 120 of the control mechanism below moves the transmission unit, it can pass through the second end of the second transmission member 140 Turn the driving mechanism partially to separate the driving mechanism from the starting plate 100, and the starting plate 100 can move to the time-telling starting position under the action of the first reset structure 210 described below. It can be understood that, according to specific assembly requirements, the position of the first eccentric nail 291 can be adjusted to adjust the initial position of the activation plate 100 . It can be understood that the first eccentric nail 291 is not limited to this limiting form, and other adjustable limiting forms can also be used, such as movable protrusions, etc., as long as it can adjust the activation plate 100 The limit function is enough.

The starting mechanism includes a first reset structure 210. The starting plate 100 is connected to the first reset structure 210. The first reset structure 210 is an elastic structure, such as a spring or a spring. One end of the first reset structure 210 is fixedly connected to the splint, and the other end is fixedly connected to the splint. The start plate 100 is connected; when the driving mechanism pushes the start plate 100 to the initial position, the start plate 100 squeezes the first reset structure 210, so that the first reset structure 210 is in a compressed state; when the driving mechanism and the start plate 100 are driven by the control mechanism When the bottom is separated, the first reset structure 210 is reset to push the activation plate 100 to move to the time-signaling activation position.

The activation board 100 includes a connecting part and a working part. In this embodiment, the connecting part and the working part are connected in a "7" shape. One end of the connecting part away from the working part is hinged with the splint, and the starting plate 100 can move around the hinged position between the initial position and the time signal starting position. One end of the first reset structure 210 in this embodiment is fixed on the splint, and the other end is connected to the connecting portion to drive the activation plate 100 to move to the time-telling activation position.

As shown in Figure 4-5, a first tooth part B and a second tooth part A are respectively provided on the inner and outer sides of the working part of the start plate 100. The second tooth part A is connected to the time reporting mechanism, and the first tooth part Part B is connected to the driving mechanism. The driving mechanism includes a driving wheel 160. A first nail 161 is provided on the front of the driving wheel 160. The first nail 161 is intermittently meshed with the first tooth portion B of the starting plate 100. During the time reporting period, the driving wheel 160 rotates once. , the first nail 161 meshes with the first tooth portion B of the activation plate 100 once, and at the same time moves the activation plate 100 to the initial position by a tooth distance. When the activation plate 100 abuts the first eccentric nail 291, the drive The wheel 160 stops rotating, and the starting plate 100 remains in the initial position waiting for the next time to start.

The driving wheel 160 of this embodiment is connected to the time-signing speed-limiting gear train 500. The time-telling speed-limiting gear train 500 is connected to the time-telling prime mover assembly. The prime mover assembly continues to provide clockwise rotation power for the driving wheel 160. The time-telling speed-limiting gear train 500 The speed of the driving wheel 160 when rotating can be limited so that the driving wheel 160 rotates at a constant speed during the time reporting, thereby ensuring that the starting plate 100 moves to the initial position at a constant speed and intermittently. It can be understood that the driving wheel 160 can also be connected to other common forms of transmission elements and driving elements, as long as the driving wheel 160 can continue to be provided with rotational power, and there is no limitation here.

As shown in Figure 1-4, the time-telling mechanism includes a weight 170 and a gong 200. When the starting plate 100 moves to the initial position, the weight 170 can be driven to strike the gong 200, thereby emitting a time-telling sound. Specifically, the weight 170 is hinged to the splint, and a time claw 171 is provided at the hinge position. The time claw 171 is connected to the weight 170 , and the time claw 171 can engage with the second tooth portion A of the activation plate 100 . When the activation plate 100 moves to the initial position, the second tooth portion A drives the time striking claw 171 to rotate to push the weight 170 to move, thereby driving the weight 170 to strike the gong 200 .

The weight 170 of this embodiment is connected to the sixth reset structure 270. The sixth reset structure 270 is an elastic structure, such as a spring or a spring. One end of the sixth reset structure 270 is fixedly connected to the splint, and the other end is connected to the weight 170; When the start plate 100 moves to the initial position, the second tooth portion A drives the time striking claw 171 to rotate and pushes the weight 170 to rotate in a direction away from the gong. At this time, the sixth reset structure 270 gradually compresses and accumulates force. When the start plate 100 When the second tooth part A breaks away from the time striking claw 171, the sixth reset structure 270 drives the weight 170 to strike the gong 200.

The time striking claw 171 of this embodiment includes a first connection end and a second connection end. The first connection end can mesh with the second tooth portion A of the activation plate 100, and the second connection end can conflict with the weight 170. When When the start plate 100 moves to the initial position, the second tooth portion A engages with the first connection end, thereby driving the time claw 171 to rotate counterclockwise, and the second connection end conflicts with the weight 170 to push the weight 170 away. The direction of the gong rotates. When the starting plate 100 moves to the time striking starting position, the second tooth portion A engages with the first connecting end, thereby driving the striking pawl 171 to rotate clockwise, and at this time, the second connecting end moves away from the weight 170 , thereby not pushing the weight 170 to move.

Preferably, the time striking claw 171 is connected to the second reset structure 220. The second reset structure 220 is an elastic structure, such as a spring or a spring. One end of the second reset structure 220 is fixedly connected to the splint, and the other end is connected to the time striking claw 171; when When the start plate 100 moves to the time striking start position, the second tooth portion A drives the time striking claw 171 to rotate. At this time, the second reset structure 220 gradually compresses. When the second tooth portion A of the starting plate 100 breaks away from the time striking claw 171, the second tooth portion A of the starting plate 100 breaks away from the time striking claw 171. The second reset structure 220 drives the time claw 171 to reset and wait for the next engagement.

It is worth noting that a limit rod 280 is also provided between the weight 170 and the gong 200. The limit rod 280 is fixedly connected to the splint. When the weight 170 strikes the gong 200, it can conflict with the limit rod 280. 280 can limit the striking depth of the heavy hammer 170. The limiting rod 280 is connected to the second eccentric nail 292, and the second eccentric nail 292 can adjust the position of the limiting rod 280. It can be understood that the second eccentric nail 292 is not limited to this limiting form, and other adjustable limiting forms, such as movable protrusions, etc., can also be used, as long as it can effectively limit the limiting rod 280. Just adjust the limit function.

As shown in Figure 1-3, the watch is equipped with an hour wheel and a minute wheel. The hour wheel is connected to the hour hand, and the minute wheel is connected to the minute hand. The hour hand and minute hand are used to display the current time. The control mechanism includes a starting dial 120. The starting dial 120 is circular. A starting protrusion is provided on the circular side wall. The starting protrusion is connected to the first end C of the first transmission member 130 in the transmission unit described below. Correspondingly, the starting dial 120 is connected to the minute wheel and rotates synchronously with the minute wheel. When the starting dial 120 rotates once, the starting protrusion will stir the first end C of the first transmission member 130, thereby turning the transmission. The unit moves once to achieve automatic time reporting on the hour.

In this embodiment, there are multiple time-telling start positions, and different time-telling start positions correspond to different times. The control mechanism includes a first limit component. The first limit component is connected to the hour wheel of the watch and rotates with the hour wheel. The first limit component is provided with a plurality of limit parts, and the limit parts correspond to the time starting position one by one. The starting mechanism includes a second limiting component. When the starting mechanism moves from the initial position to the corresponding time alarm starting position, the second limiting component can conflict with the corresponding limiting portion on the first limiting component.

Specifically, the first limiting component of this embodiment is the time cam 110. The time cam 110 is connected to the time wheel and rotates synchronously with the time wheel. The time cam 110 is provided with 12 steps with increasing depth, and the 12 steps correspond to 12 steps. hour, the minute wheel drives the starting dial 120 to rotate one circle, which is one hour, and the hour wheel drives the time cam 110 to rotate one step, which is also one hour. The steps of the striking cam 110 correspond to the second limiting component of the starting mechanism described below, that is, the positioning head 101 described below. Different step depths limit the striking starting position of the starting mechanism.

The starting mechanism includes a positioning head 101. The positioning head 101 is arranged on the starting plate 100. When the starting plate 100 moves to the time-telling start position, the positioning head 101 can conflict with the steps on the time-telling cam 110 to limit the time of the starting plate 100 this time. As for the time starting position, since the time cam is provided with 12 steps with increasing depth, the starting plate 100 has 12 starting positions for the time. Since the moving distance of the starting plate 100 to the initial position is different, the 12 hours can be set on the hour respectively. Tell time.

As shown in Figures 1-3, the transmission unit includes a first transmission member 130 and a second transmission member 140. One end of the first transmission member 130 corresponds to the starting dial 120, and the other end is connected to the second transmission member 140. The transmission member 140 is connected to the driving mechanism. The starting dial 120 moves by turning the first transmission member 130, thereby driving the second transmission member 140 to push the driving mechanism to separate from the starting plate 100.

Specifically, the first transmission member 130 is hinged to the splint. The first transmission member 130 has three rod-shaped structures extending away from the hinge point at the position of the first transmission member 130 being hinged to the splint. End B and first end C. The first end C corresponds to the starting dial 120. One rotation of the starting dial 120 can move the first end C of the first transmission member 130 upward once, thereby driving the first transmission member 130 to rotate counterclockwise. once.

The second end A of the first transmission member 130 is connected to the second transmission member 140. The second transmission member 140 is hinged with the clamping plate. The second transmission member 140 extends in a direction away from the hinge point at a position hinged with the clamping plate. Two rod-shaped structures are respectively a first end and a second end. The second end A of the first transmission member 130 is connected to the first end of the second transmission member 140 , and the second end A of the second transmission member 140 is connected to the driving wheel 160 . Specifically, the first end of the second transmission member 140 is provided with a third nail, and the second end A of the first transmission member 130 can conflict with the third nail to make the first transmission member 130 counterclockwise. When rotating, the second transmission member 140 can be pushed to rotate in a clockwise direction.

As shown in FIG. 5 , a second nail 162 is provided on the back of the driving wheel 160 , and the second end of the second transmission member 140 can conflict with the second nail 162 to cause the second transmission member 140 to rotate clockwise. , the driving wheel 160 can be pushed to rotate in the counterclockwise direction, so that the first nail 161 of the driving wheel 160 is separated from the first tooth portion B of the activation plate 100 . It is worth noting that since the prime mover component continues to provide clockwise rotation power for the driving wheel 160, the torque provided by the starting dial 120 needs to be greater than the clockwise rotation torque of the driving wheel 160, so that the starting dial 120 can pass the first The first transmission member 130 and the second transmission member 140 stir the driving wheel 160 to rotate counterclockwise. The specific torque value is calculated based on actual conditions and will not be described in detail here.

It is worth noting that the first transmission member 130 includes a fifth return structure 260. The fifth return structure 260 is an elastic structure, such as an elastic piece or a spring. One end of the fifth return structure 260 is fixedly connected to the splint, and the other end is connected to the first transmission structure. The fifth reset structure 260 of this embodiment is connected to the first end C of the first transmission member 130; when the watch is adjusting the time, the minute wheel drives the starting dial 120 to rotate in the reverse direction to drive the first The transmission member 130 rotates counterclockwise and compresses the fifth reset structure 260. The start dial moves the first transmission member 130 downward, and the fifth reset structure 260 is in a compressed state; when the start dial 120 is separated from the first transmission member 130, The fifth reset structure 260 can drive the first transmission member 130 to reset.

The second transmission member 140 is connected to a third reset structure 230. The third reset structure 230 is an elastic structure, such as a spring or a spring. One end of the third reset structure 230 is fixedly connected to the splint, and the other end is connected to the second transmission member 140; When the start dial 120 moves the first end C of the first transmission member 130 to lift upward, the first transmission member 130 pushes the second transmission member 140 to rotate in a clockwise direction and compresses the third reset structure 230 . After the starting dial 120 is separated from the first end C of the first transmission member 130, the third reset structure 230 can drive the second transmission member 140 and the first transmission member 130 to reset to wait for the next dialing operation of the starting dial 120. move.

Specifically, the stop mechanism of this embodiment is a pawl 150. The pawl 150 can mesh with the first tooth portion B of the activation plate 100. The pawl 150 can limit the moving direction of the activation plate 100. When the activation plate 100 When moving to the initial position, the driving wheel 160 and the starting plate 100 are intermittently meshed, so the driving wheel 160 and the starting plate 100 will be separated briefly. At this time, the first reset structure 210 will drive the starting plate 100 to retreat (towards the time starting position). (direction movement), the pawl 150 can prevent the activation plate 100 from retreating, that is, the limit state.

The pawl 150 is hinged with the splint. At the position where the pawl 150 is hinged with the splint, two rod-shaped structures extend in a direction away from the hinge point. They are a limit rod and a reset rod, which are the reset end of the stop mechanism. and limiting ends. The limiting rod can conflict with the first tooth portion B of the activation plate 100 to limit the moving direction of the activation plate 100 . The tooth surface of the side of the first tooth portion B of the activation plate 100 close to the pawl 150 can conflict with the end surface of the limiting rod to prevent the activation plate 100 from retreating, and the first tooth portion B of the activation plate 100 is away from the pawl. The tooth surface on one side of 150 is inclined, and the side surface of the limit lever can slide with the inclined tooth surface. When the starting plate 100 moves to the initial position, the starting plate 100 can drive the pawl 150 to rotate clockwise, so that the starting plate 100 can rotate clockwise. The first tooth portion B of the plate 100 is separated from the pawl 150. Therefore, the pawl 150 does not restrict the movement of the activation plate 100 toward the initial position.

The reset rod of the pawl 150 is connected to the fourth reset structure 240. The fourth reset structure 240 is an elastic structure, such as a spring or a spring. One end of the fourth reset structure 240 is fixedly connected to the splint, and the other end is connected to the pawl 150. This structure The fourth reset structure 240 of the embodiment is connected to the reset rod of the pawl 150 . When the activation plate 100 moves to the initial position, the activation plate 100 can drive the pawl 150 to rotate clockwise to compress the fourth reset structure 240. When the first tooth portion B of the activation plate 100 is separated from the pawl 150 , the fourth reset structure 240 can drive the pawl 150 to reset and engage with the next tooth on the B side of the activation plate 100 to continue to limit the activation plate 100 . The reset rod of the pawl 150 can be connected to the second limiting nail 294. The second limiting nail 294 is fixedly connected to the splint. The second limiting nail 294 can limit the position of the pawl 150 so that the reset pawl 150 can It meshes with the first tooth portion B of the activation plate 100 . It can be understood that the second limiting nail 294 can also be provided at the position of the limiting rod, as long as the reset pawl 150 can engage with the first tooth portion B of the activation plate 100. In addition, It is not limited to the limiting form of the second limiting nail 294, and other limiting forms, such as protrusions, can also be used, as long as they can limit the pawl 150.

It is worth noting that the reset lever of the pawl 150 also corresponds to the third end B of the first transmission member 130. When the start dial 120 moves the first end C of the first transmission member 130 and lifts up, the third end B of the first transmission member 130 is raised. The third end B of a transmission member 130 rotates in the counterclockwise direction, and the reset lever of the pawl 150 is rotated in the clockwise direction, thereby separating the pawl 150 from the first tooth portion B of the activation plate 100. When the fourth reset structure 240 is compressed, that is, in a separated state, the restriction on the activation plate 100 is released, so that the activation plate 100 can move to the time-telling start position driven by the first reset structure 210 . When the starting dial 120 is separated from the first end C of the first transmission member 130, the fourth reset structure 240 recovers its shape to drive the ratchet 150 to reset to the limiting state.

The automatic time reporting structure of this embodiment also includes a safety unit. The safety unit is set correspondingly to the starting mechanism. The safety unit has a safety opening position and a safety closing position. When the safety unit is in the safety opening position, the safety unit and the starting mechanism are connected to each other to lock the start. The position of the mechanism; when the safety unit is in the safety closing position, the safety unit and the starting mechanism are separated from each other to unlock the starting mechanism.

Specifically, as shown in Figure 6-9, the start plate 100 is connected to the safety unit, and the safety unit can lock the start plate to prevent the start plate 100 from moving toward the time starting position when the watch is adjusting the time. As a result, the positioning head 101 and the time cam 110 collide.

Specifically, the safety unit includes a safety rod 300, the middle position of the safety rod 300 is hinged with the nail tube, and the nail tube is fixed on the splint. The safety lever 300 can move between the safety closed position and the safety open position; when the safety lever 300 is in the safety open position, one end of the safety lever 300 is engaged with the activation plate 100 to lock the activation plate 100; when the safety lever 300 is in the safety closing position position, one end of the safety lever 300 is detached from the start plate 100, and the control mechanism can control the start plate 100 to move from the initial position to the time starting position.

One end of the safety lever 300 is provided with a safety hook, and the safety hook can be engaged with the activation plate 100 to limit the movement of the activation plate 100 . The launch plate 100 of this embodiment is provided with a third limiting nail 295, and the safety hook can be engaged with the third limiting nail 295. It can be understood that the shape of the launch plate 100 can also be directly changed to engage with the bumper 300, as long as it can limit the position of the launch plate 100.

The other end of the safety lever 300 is connected to the pull stop pin 400. The pull stop pin 400 can drive the safety lever to rotate. The pull stop pin 400 of this embodiment is fixedly arranged on the safety drive plate 401. When the safety drive plate 401 moves, it can be pulled by the safety drive plate 401. The blocking pin 400 drives the safety lever 300 to rotate, so that the safety lever 300 moves between the safety closing position and the safety opening position. The safety drive plate 401 is connected to the time adjustment unit. The time adjustment unit includes a stem. The stem can drive the safety drive plate 401 to move. When the stem is pulled out to adjust the time, the safety drive plate 401 drives the safety lever to rotate and connects with the start plate. The third limiting nail 100 is engaged with 295 phases to realize the insurance function.

It is worth noting that, as shown in Figure 6, when the starting mechanism moves, the traveling trajectory of the center point of the third limiting nail 295 is the first trajectory, that is, the dotted line of the outer circle, and the inner edge point of the third limiting nail 295. The traveling trajectory is the second trajectory, which is the dotted line of the inner circle. The safety closing position of the safety hook is inside the second track. At this time, the activation plate 100 can move freely without conflicting with the safety hook.

As shown in Figure 7, when the time is not sounded and the stem is pulled out, the safety hook is in the safety open position, and the safety hook is engaged with the third limiting nail 295 on the starting plate 100. At this time, the starting plate 100 cannot be moved at will. Therefore, even during the time adjustment process, when the starter dial 120 moves the transmission unit to separate the driving mechanism from the starter plate 100, the system cannot report the time, thereby preventing collision failures.

Preferably, the side of the safety hook of this embodiment that contacts the third limiting nail 295 on the activation plate 100 is designed to be arc-shaped, and the safety opening position of the arc-shaped safety hook is set between the first trajectory and the start plate 100. Between the second trajectories, the dotted line shown in Figures 8-9 is the trajectory that the center of the limit nail 295 of the activation plate 100 can travel. At this time, the contact between the safety hook and the third limit nail 295 is smooth, and the watch user can push back the stem at any time. Even if the safety hook collides with the third limit nail 295, the timekeeping system will not be damaged.

The function of the safety hook provided on the safety lever 300 is to pull out the stem when the time is not being struck, and the safety hook can hook the third limiting nail 295. Even if the stem is pulled out or pushed back by mistake when the time is being struck, the watch will not be damaged. It has a structure and does not affect the return of the launch pad 100 to its initial position.

In actual time adjustment work, the working process of the insurance unit has the following three situations:

The first situation: when the time is not reported and the needle needs to be moved clockwise, when the stem is pulled out, the pull nail 400 on the safety driving plate 401 drives the safety lever 300 to rotate, and the end with the safety hook just hooks the starter The third limiting nail 295 on the plate 100 prevents its rotation. So when the start dial 120 is turned to start the entire time reporting system, since the starting plate 100 cannot rotate, the system cannot report the time, thereby preventing collision failures.

In the second case, when the time is not reported and the needle needs to be moved counterclockwise, the travel status of the safety lever 300 is the same as above. The start dial 120 rotates counterclockwise to turn the first start lever 130, and the first start lever 130 rotates clockwise. It comes into contact with the second starting lever 140 and the pawl 150, and the fourth reset structure 260 provides a restoring force. When the counterclockwise movement of the needle is completed, the first starting lever 130 returns to the rest position, and the system will not tell the time.

In the third case, when the stem is pulled out for adjustment during the time reporting process, the start plate 100 is already in the process of being lifted, and its third limiting nail 295 will come into contact with the safety hook of the safety lever 300. Due to the The outer side of the safety hook is set in an arc shape, so the outer side of the safety hook is in smooth contact with the third limiting nail 295. At this time, the stem can be directly pushed back to return the starting plate 100 to its original position without damaging the timekeeping system.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it can still be used Modifications are made to the technical solutions described in the foregoing embodiments, or equivalent substitutions are made to some of the technical features; however, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
