One end of the lever away from the pawl abuts against the circumferential surface of the cam, and one end of the pawl away from the lever has a ratchet tooth for engaging with the card slot.

[0014] In one embodiment, the lever has a first arc segment and a second arc segment integrally connected to the first arc segment. The openings of the first arc segment and the second arc segment are arranged opposite to each other; wherein,

[0015] The connection part of the first arc segment and the second arc segment is rotatably connected to the base plate. One end of the first arc segment away from the second arc segment abuts against the circumferential surface of the cam, and one end of the second arc segment away from the first arc segment is rotatably connected to the pawl.

[0022] The beneficial effects of the watch movement provided by the present application are as follows: Compared with the prior art, the cam in the watch movement of the present application can be connected to the minute hand. When the cam rotates clockwise one full circle, it represents one hour. When the cam rotates clockwise one full circle, it drives the rotating ring to rotate once, and when the rotating ring rotates once, the hour jumps once. When the cam rotates clockwise relative to the substrate, it can drive the flyback mechanism through the driving surface and cause the other end of the flyback mechanism to disengage from the previous card slot in the counterclockwise direction. When the cam continues to rotate clockwise relative to the substrate, one end of the flyback mechanism can be disengaged from the driving surface and enter the instant jump surface to cause an instant jump, and the other end of the flyback mechanism enters the next card slot in the clockwise direction and drives the rotating ring to engage with the gear through the meshing teeth, thereby driving the gear to rotate. The previous gear and the next gear arranged in the clockwise direction can both be driven to rotate by the rotating ring. When the previous gear rotates, it can drive the decorative piece connected to it to rotate into the area blocked by the dial, and when the next gear rotates, it can drive the decorative piece connected to it to rotate out of the area not blocked by the dial. At a specific moment, only the decorative piece corresponding to one gear can be seen, and the rest of the decorative pieces are hidden in the area blocked by the dial. Therefore, the observer can identify the time point according to the displayed decorative piece.

[0038] The watch movement and watch provided by the embodiments of this application will now be described.

[0039] Please refer to Figures 1 to 6 As shown, the watch movement provided by this application includes: a substrate 10, the substrate 10 having a central axis and being disc-shaped; a rotating ring 20, the rotating ring 20 being coaxially and rotatably connected to the substrate 10, and a plurality of concave card slots 201 being provided on the inner ring wall of the rotating ring 20 at circumferential intervals along the rotating ring 20, and a plurality of meshing teeth 202 being provided on the outer ring wall of the rotating ring 20 at circumferential intervals along the rotating ring 20; a plurality of gears 30, the gears 30 being rotatably connected to the substrate 10 and being used for meshing with the meshing teeth 202, and the plurality of gears 30 being arranged at circumferential intervals along the substrate 10; a cam 40, the cam 40 being coaxially and rotatably connected to the substrate 10, the circumferential surface of the cam 40 including a driving surface 401 having a proximal end 4011 and a distal end 4012, and a quick-return surface 402 connected between the proximal end 4011 and the distal end 4012; the driving surface 401 extending along the circumference of the cam 40, and the driving surface 401 gradually moving away from the center of the cam 40 in the direction from the proximal end 4011 to the distal end 4012; a quick-return mechanism 50, the quick-return mechanism 50 being rotatably connected to the substrate 10, one end of the quick-return mechanism 50 abutting against the circumferential surface of the cam 40, and the other end of the quick-return mechanism 50 being used for being snap-connected to the card slot 201.

[0040] Among them, the cam 40 can rotate clockwise relative to the substrate 10. The cam 40 can drive the other end of the quick-return mechanism 50 to disengage from the previous card slot 201 in the counterclockwise direction through the driving surface 401, and the cam 40 can force the other end of the quick-return mechanism 0 to enter the next card slot 201 in the clockwise direction through the quick-return surface 402 and drive the rotating ring 20 to drive the gears 30 and the decorative parts to rotate.

[0041] It should be noted that in the embodiments of this application, the substrate 10 has a central hole penetrating its thickness, and the substrate 10 is coaxially mounted on the main plate of the basic movement of the watch (not shown in the figure). A center wheel shaft is coaxially and rotatably connected to the main plate, and the center wheel shaft passes through the central hole of the substrate 10 and is fixedly connected to the cam 40, thereby constituting the support and drive for the cam 40.

[0042] The beneficial effects of the watch movement provided by this application are as follows: Compared with the prior art, in the watch movement of this application, the cam 40 can be connected to the minute hand. When the cam 40 rotates clockwise one full circle, it represents one hour. When the cam 40 rotates clockwise one full circle, it drives the rotating ring 20 to rotate once, and when the rotating ring 20 rotates once, the hour jumps once. When the cam 40 rotates clockwise relative to the base plate 10, it can drive the flyback mechanism 50 through the driving surface 401 and cause the other end of the flyback mechanism 50 to disengage from the previous card slot 201 in the counterclockwise direction; when the cam 40 continues to rotate clockwise relative to the base plate 10, one end of the flyback mechanism 50 can disengage from the driving surface 401 and enter the instant jump surface 402 to cause an instant jump, and the other end of the flyback mechanism 50 enters the next card slot 201 in the clockwise direction and drives the rotating ring 20 to engage with the gear 30 through the meshing teeth 202, thereby driving the gear 30 to rotate. The previous gear and the next gear arranged in the clockwise direction can both be driven to rotate by the rotating ring. When the previous gear rotates, it can drive the decorative part connected to it to rotate into the area blocked by the dial, and when the next gear rotates, it can drive the decorative part connected to it to rotate out to the area not blocked by the dial. At a specific moment, only the decorative part corresponding to one gear can be seen, and the rest of the decorative parts are hidden in the area blocked by the dial. Therefore, the observer can identify the time point according to the displayed decorative part. In this way, by changing the time indication method of traditional watches, the fun of the observer reading the current time is improved.

[0043] Among them, in the embodiments of this application, the decorative part can be a decorative part representing the 12 Chinese zodiac signs, or 12 different cartoon or figurine decorative parts, or decorative parts such as colored lights with different luminous colors. In the embodiments of this application, the decorative part can be a plate member provided with graphics and patterns, and the decorative part can also be a hollowed-out member or a sculptured member.

[0044] In this embodiment, on one of the side surfaces of the base plate 10 facing the rotating ring 20 and the side surface of the rotating ring 20 facing the base plate 10, an annular groove is provided on one of them, and an annular protrusion is provided on the other of them. The rotating ring 20 is rotatably and coaxially clamped to the base plate 10 through the annular groove and the annular protrusion.

[0045] As Figure 1 shown, in one embodiment, the watch movement further includes a fixing ring 90. The fixing ring 90 and the base plate 10 are arranged on both sides of the rotating ring 20 along the axial direction of the rotating ring 20, and moreover, the rotating ring 20 is coaxially and rotatably connected to the fixing ring 90. The fixing ring 90 and the base plate 10 are fastened and connected by a threaded member. The rotational connection manner between the rotating ring 20 and the fixing ring 90 is the same as the rotational connection manner between the rotating ring 20 and the base plate 10.

[0046] As Figure 4As shown in the figure, 12 card slots 201 are provided on the inner ring wall of the rotating ring 20. The 12 card slots 201 are evenly spaced along the circumferential direction of the rotating ring 20. The card slots 201 are inclined and recessed inward from the inner ring wall of the rotating ring 20, and the card slots 201 are inclined and recessed inward along the clockwise direction of the rotating ring 20, thereby forming a wedge-shaped groove that deviates towards the clockwise direction.

[0047] As Figure 4 shown in the figure, several engaging teeth 202 on the outer ring wall of the rotating ring 20 form an engaging tooth group. There are two engaging tooth groups spaced along the circumferential direction of the rotating ring 20 on the outer ring wall of the rotating ring 20, and the distance between the two engaging tooth groups is equal to the distance between two adjacent gears 30. When the rotating ring 20 rotates clockwise, the two engaging tooth groups engage with the corresponding two gears 30 one by one and drive the two gears 30 to rotate.

[0048] As Figure 4 shown in the figure, preferably, an indented avoidance groove 2021 is provided on the outside of each of the two outermost engaging teeth 202 in the engaging tooth group. Due to the design of the avoidance groove 2021, when the gear 30 starts to engage, the avoidance groove 2021 at the front end can be used to accommodate the teeth of the gear 30 to avoid jamming; when the gear 30 starts to disengage, the avoidance groove 2021 at the rear end can be used to accommodate the teeth of the gear 30 to avoid jamming.

[0049] As Figure 1 and Figure 2 shown in the figure, the watch movement includes 12 gears 30, and interesting patterns or graphics can be connected to the 12 gears 30, such as the patterns of the 12 Chinese zodiac signs. The 12 gears 30 are sequentially spaced along the circumferential direction of the substrate 10, and each gear 30 is rotationally connected to the substrate 10 through a gear shaft. The 12 gears 30 exactly correspond to 12 time points.

[0050] In one embodiment, preferably, the tooth surface of the gear 30 includes two engaging segments 301 with teeth and two non-engaging segments 302 with smooth surfaces. That is to say, a number of teeth are provided on the engaging segments 301, and the number of teeth is used to engage with a number of engaging teeth 301 on the rotating ring 20, while the non-engaging segments 302 are designed with smooth surfaces. The two engaging segments 301 and the two non-engaging segments 302 are alternately arranged along the circumferential direction of the gear 30. In this way, the gear 30 is designed as an incomplete gear. In the non-engaging stage, the non-engaging segments 302 of the gear 30 face the smooth surface part of the outer ring wall of the rotating ring 20, and the gear 30 cannot rotate.

[0051] Apply the watch movement provided by this application to a watch. Connect the minute hand of the watch to the core of the cam 40. The cam 40 can drive the minute hand to rotate, and one rotation of the cam 40 driving the minute hand is a cycle. During one cycle, when the cam 40 rotates clockwise relative to the base plate 10, it can drive the flyback mechanism 50 through the driving surface 401. During this process, the flyback mechanism 50 rotates relative to the base plate 10, and one end of the flyback mechanism 50 moves from its proximal end 4011 to the distal end 4012 relative to the driving surface 401, while the other end of the flyback mechanism 50 disengages from the previous card slot 201 in the counterclockwise direction.

[0052] During the same cycle, when the cam 40 continues to rotate clockwise relative to the base plate 10, at this time, one end of the flyback mechanism 50 disengages from the driving surface 401 at the distal end 4012 of the driving surface 401 and enters the instantaneous jump surface 402 to occur an instantaneous jump. After the instantaneous jump, one end of the flyback mechanism 50 flies back to the proximal end 4011 of the driving surface 401, while the other end of the flyback mechanism 50 enters the next card slot 201 in the clockwise direction and drives the rotating ring 20 to be engaged with the gear 30 through the engaging teeth 202, thereby driving the gear 30 to rotate.

[0053] As Figure 4 shown, two spaced engaging tooth groups are provided on the outer ring wall of the rotating ring 20. During the flyback process of the flyback mechanism 50, the two engaging tooth groups are respectively engaged with two adjacent gears 30. The two adjacent gears 30 are the previous gear 30 and the next gear 30 arranged in sequence in the clockwise direction. Through the engagement of the teeth, the rotation of the previous gear 30 can drive the interesting pattern or graphic thereon to rotate into the area blocked by the dial, and the rotation of the next gear 30 can drive the interesting pattern or graphic thereon to rotate out to the area not blocked by the dial, so that the previous moment is hidden and the next moment appears at the same time.

[0054] In one embodiment, the flyback mechanism 50 includes a lever 501 rotatably connected to the base plate 10 and a pawl 502 rotatably connected to the lever 501. One end of the lever 501 away from the pawl 502 abuts against the circumferential surface of the cam 40. One end of the pawl 502 away from the lever 501 has a ratchet tooth 5021 for engaging with the card slot 201. Among them, the ratchet tooth 5021 is arranged at an acute angle with the body part of the pawl 502, and the deflection angle of the pawl 5021 is the same as the deflection angle of the above-mentioned card slot 201, so that the shape of the ratchet tooth 5021 can better adapt to the shape of the card slot 201, thereby improving the fitting degree of the engagement.

[0055] In one embodiment, the lever 501 has a first arcuate section 5011 and a second arcuate section 5012 integrally connected to the first arcuate section 5011. The openings of the first arcuate section 5011 and the second arcuate section 5012 are arranged opposite to each other. Wherein, the integral connection part of the first arcuate section 5011 and the second arcuate section 5012 is rotatably connected to the substrate 10. One end of the first arcuate section 5011 away from the second arcuate section 5012 abuts against the peripheral surface of the cam 40. One end of the second arcuate section 5012 away from the first arcuate section 5012 is rotatably connected to the pawl 502.

[0056] Specifically, the length of the second arcuate section 5012 is greater than that of the first arcuate section 5011. The openings of the first arcuate section 5011 and the second arcuate section 5012 are both opened towards the cam 40, so as to be spaced apart from the peripheral edge of the cam 40 by a certain distance to prevent interference with each other.

[0057] In one embodiment, the watch movement further includes a rod spring 60 connected to the substrate 10. The pressing end 601 of the rod spring 60 presses on the outer convex side of the first arcuate section 5011, so that the first arcuate section 5011 is always in contact with the driving surface 401. In this embodiment, it is preferred that the rod spring 60 is an elastic arcuate rod, and the opening of the rod spring 60 is opened towards the cam 40, so as to be spaced apart from the peripheral edge of the cam 40 by a certain distance to prevent interference with each other.

[0058] In one embodiment, the fly-back mechanism 50 further includes a positioning rod 80. A convex structure 5013 is provided in the area of the lever 501 close to the pawl 502. A chute 5014 parallel to the lever 501 and penetrating through the convex structure 5013 is provided on the convex structure 5013. One end of the positioning rod 80 is movably placed in the chute 5014 and can move along the length direction of the chute 5014. The other end of the positioning rod 80 has a positioning hook portion 801. The positioning hook portion 801 is hooked on the pawl 502. In this way, when the pawl 502 rotates relative to the lever 501, the rotation angle of the pawl 502 can be limited by the positioning hook portion 801, so that when the pawl 502 disengages from the previous card slot 201 and enters the next card slot 201, it can just enter the next card slot 201 along the set path, and will not deflect too much during this process and get stuck on the part of the inner wall of the rotating ring 20 that is not the card slot 201.

[0059] In one embodiment, the watch movement further includes a positioning spring 70. The fixed end 701 of the positioning spring 70 is connected to the substrate 10. The positioning end 702 of the positioning spring 70 is used for clamping in the card slot 201, and the fixed end 701 and the positioning end 702 are arranged in sequence in the clockwise direction. Before the pawl 502 disengages from the previous card slot 201 and enters the next card slot 201 relative to the rotating ring 20, since the positioning end 702 of the positioning spring 70 presses in the card slot 201, the rotating ring 20 does not rotate during this process. When one end of the lever 501 reaches the distal end 4012 of the cam 40 and instantaneously drops, the other end of the lever 501 will instantaneously drive the pawl 502 into the next card slot 201 and drive the rotating ring 20 to rotate clockwise. At this time, the rotating ring 20 disengages from the positioning of the positioning spring 70 and rotates clockwise. That is to say, the positioning end 702 of the positioning spring 70 can allow the rotating ring 20 to rotate clockwise and can prevent the rotating ring 20 from rotating counterclockwise.

[0060] In this embodiment, the positioning end 702 of the positioning spring 70 has a wedge-shaped surface, which exactly matches one side of the card slot 201. The wedge-shaped surface on the positioning end 702 matches one side of the card slot 201, and the two are separable. When the rotating ring 20 rotates clockwise, the rotating ring 20 can drive the positioning end 702 to move towards the inner side of the substrate 10 so that it can be smoothly moved away from the rotation path of the rotating ring 20, and the positioning spring clamps the rotating ring 20 in the clockwise direction, so that the rotating ring 20 cannot move it away from the rotation path and rotate counterclockwise.

[0061] Another object of the present application is also to provide a watch. The watch includes a watch dial, the watch dial can be covered on the above-mentioned fixed ring 90, and 12 visible areas spaced at intervals along the circumferential direction of the watch dial can be arranged on the watch dial. The visible area is a hollow hole structure area or a transparent area. The watch further includes the above-mentioned watch movement, and the 12 gears 30 on the watch movement are arranged in one-to-one correspondence with the above-mentioned 12 visible areas.

[0062] The beneficial effects of the watch provided by the present application compared with the prior art are the same as the beneficial effects of the watch movement provided by the present application compared with the prior art, and will not be elaborated here.

[0063] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
