[0027] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a watch, which includes a watch case, a movement, a pointer and an opening and closing structure. The watch case, the movement and the pointer are all existing structures and are not described here. Among them, the movement is arranged in the watch case, the opening and closing structure is arranged in the watch case and located on the upper surface of the movement, and the movement has an hour wheel 7. When the watch is working normally, the hour wheel 7 will continue to rotate, and the pointer is arranged on the hour wheel 7 and rotates synchronously with the hour wheel 7. The opening and closing structure can display different patterns, thereby ensuring the beauty of the appearance of the watch and improving the grade of the watch. In the present application, the hour wheel 7 of the movement serves as the power source of the opening and closing structure.

[0028] Specifically, Figure 1-Figure 3 As shown, in this embodiment, the opening and closing structure includes: a mounting plate 1, an engagement mechanism 2, a plurality of blades 3, a swinging member 4 and an elastic member 5. Among them, the mounting plate 1 is arranged on the movement of the watch, and a through hole 11 is arranged at the center of the mounting plate 1. A cam 6 is arranged at the through hole 11. The cam 6 is fixedly connected with the hour wheel 7 on the movement and rotates synchronously with the hour wheel 7. When the hour wheel 7 rotates, the cam 6 will be driven to rotate synchronously. The through hole 11 is used to realize the rotation installation of the cam 6; the swinging member 4 abuts against the outer peripheral surface of the cam 6 through the elastic member 5 and swings with the rotation of the cam 6. The swinging member 4 is also meshed with the meshing mechanism 2. When the cam 6 rotates, the swinging member 4 will be driven to rotate. When the swinging member 4 rotates, the meshing mechanism 2 will be synchronously driven to rotate; the meshing mechanism 2 is fixedly connected with each blade 3. When the meshing mechanism 2 rotates clockwise or counterclockwise, it will drive multiple blades 3 to disperse clockwise or gather counterclockwise. When multiple blades 3 gather or disperse with each other, different display patterns will be presented, so as to ensure that the display pattern of the opening and closing structure is dynamic, thereby achieving the purpose of improving the grade of the watch.

[0029] An opening and closing structure provided in an embodiment of the present application is that when the movement works normally, the hour wheel 7 will continue to rotate, thereby driving the cam 6 to rotate. During the rotation, the cam 6 drives the swinging member 4 and the meshing mechanism 2 to rotate, so that the meshing mechanism 2 drives the blades 3 to rotate, so that when the blades 3 rotate clockwise, the blades 3 are dispersed. After the cam 6 rotates one circle, the elastic member 5 drives the swinging member 4 and the meshing mechanism 2 to reset. When the blades 3 rotate counterclockwise, the blades 3 gather. Each blade 3 presents a different pattern in the process of gathering and dispersing, and the surface of the blade 3 can also be designed with different patterns, so that the opening and closing structure can display different patterns, thereby improving the grade of the watch.

[0030] like Figure 2-Figure 4 As shown, in this embodiment, the meshing mechanism 2 includes: a gear ring 21 rotatably arranged on the mounting plate 1, and a plurality of gears 22 rotatably arranged on the mounting plate 1 at intervals, the gear ring 21 is a circular ring, the gear ring 21 includes an outer tooth 211 and an inner tooth 212, the outer tooth 211 is meshed and connected with the swing member 4, the inner tooth 212 is meshed and connected with each gear 22, and each gear 22 is fixedly connected with the corresponding blade 3. Specifically, each blade 3 is fixedly connected with the corresponding gear 22 through a positioning shaft, the positioning shaft is used to rotatably set the gear 22 on the mounting plate 1, and the gear ring 21 is used to transmit the transmission force of the swing member 4 to the gear 22, so that the gear 22 drives the blade 3 to rotate.

[0031] In this embodiment, the blade 3 is a fan-shaped blade, and the outer peripheral surface of the fan-shaped blade is an arc surface. The fan-shaped blade has three arc surfaces, which makes the shape of the blade 3 more beautiful, and different patterns or colors can be designed on each blade 3. Among them, the blade 3 is provided with five pieces, and the five blades 3 are gathered together to form a flower shape, which is very beautiful.

[0032] In this embodiment, if Figure 2-Figure 4As shown, the swing member 4 includes: an arc-shaped rack 41, a first connecting rod 42, a second connecting rod 43 and an abutment block 44. Among them, one end of the first connecting rod 42 is connected to one end of the second connecting rod 43 and the connection is rotatably arranged on the mounting plate 1 through a rotating shaft 45, the other end of the first connecting rod 42 is connected to the arc-shaped rack 41, and the other end of the second connecting rod 43 is fixedly connected to the abutment block 44, the abutment block 44 and the second connecting rod 43 are hook-shaped, the arc-shaped gear 22 is meshed with the external teeth 211, and the abutment block 44 abuts on the outer peripheral surface of the cam 6. The connection between the first connecting rod 42 and the second connecting rod 43 is rotatably arranged on the mounting plate 1 through a rotating shaft 45, which is convenient for installation. There is an angle between the first connecting rod 42 and the second connecting rod 43, and in this embodiment, the angle is an acute angle. The first connecting rod 42 and the second connecting rod 43 rotate synchronously. When the cam 6 rotates, the second connecting rod 43 is driven to rotate through the abutment block 44, thereby driving the first connecting rod 42 to rotate with the rotating shaft 45 as a fixed point, so that the first connecting rod 42 drives the arc rack 41 to make an arc motion and drives the ring gear 21 to rotate. When the ring gear 21 rotates, it drives each gear 22 to rotate, thereby realizing the rotation of each blade 3.

[0033] Specifically, Figure 4 As shown, in this embodiment, a first ring 421 is provided at one end of the first connecting rod 42, a second ring 431 is provided at one end of the second connecting rod 43, a convex block 422 is provided on the first ring 421, an angle is formed between the convex block 422 and the first connecting rod 42, a first mounting hole 423 is provided on the convex block 422, a second mounting hole 432 is provided on the second connecting rod 43, the first ring 421 and the second ring 431 are sleeved on the rotating shaft 45, and the first mounting hole 423 and the second mounting hole 432 are coaxial, and a positioning pin (not shown in the figure) is inserted in the first mounting hole 423 and the second mounting hole 432, so that the positioning pin is used to connect the first connecting rod 42 and the second connecting rod 43 together so that they rotate synchronously. In other embodiments, the first mounting hole 423 and the second mounting hole 432 are connected by bolts, or a positioning column is provided on the second connecting rod 43, and the first mounting hole 423 is sleeved on the positioning column.

[0034] In this embodiment, the first connecting rod 42 and the second connecting rod 43 are rotatably installed by sleeve-arranging the first ring 421 and the second ring 431, which has the advantage of convenient installation and also facilitates the production of the swing member 4. In this embodiment, the cross-sections of the first connecting rod 42 and the second connecting rod 43 are both square, the first connecting rod 42 and the second connecting rod 43 are both curved rods, the first connecting rod 42 and the arc-shaped rack 41 are integrally formed, and the second connecting rod 43 and the abutment block 44 are integrally formed. In other embodiments, the first connecting rod 42 and the second connecting rod 43 are integrally formed.

[0035] In this embodiment, the outer circumference of the cam 6 is in an involute shape, and one circle of the outer circumference of the cam 6 has a height difference, that is, the radius of the cam 6 changes from small to large, so that the starting position and the end position have a height difference. When the abutment block 44 abuts at the starting position (the smallest radius of the cam 6), the blades 3 are in a gathered state. When the wheel 7 rotates clockwise, the cam 6 is driven to rotate clockwise. Since the outer circumference of the cam 6 is in an involute shape, the cam 6 drives the abutment block 44 and the second connecting rod 43 to rotate during the rotation process, thereby driving the first connecting rod 42 and the arc-shaped rack 41 to rotate, the arc-shaped rack 41 drives the gear ring 21 to rotate, and the gear ring 21 drives the gear 22 to rotate, thereby driving the blades 3 to rotate and disperse. When the cam 6 rotates one circle to the end position (the largest radius of the cam 6), each blade 3 is in a fully open state. When the abutment block 44 abuts against the starting position from the end position, the elastic force of the elastic member 5 pushes the second connecting rod 43 to rotate counterclockwise, thereby driving the first connecting rod 42 and the arc-shaped rack 41 to rotate counterclockwise, and driving the ring gear 21 and the gear 22 to rotate, so that each blade 3 rotates instantly and returns to the gathered state. At this time, each blade 3 completes an opening and closing action, and the cycle continues. The opening and closing action of the opening and closing structure is realized with the rotation of the hour wheel 7. Therefore, as long as the watch can continue to work, the blades 3 of the opening and closing structure will continue to gather and disperse, so that the display pattern of the watch continues to change, ensuring its aesthetics.

[0036] In other embodiments, the radius of the cam 6 changes smoothly, and there is no sudden change point of the radius on the surface of the cam 6 , that is, when the second connecting rod 43 swings with the rotation of the cam 6 , there is no sudden change position of the swing.

[0037] like Figure 2-Figure 4As shown, in this embodiment, the mounting plate 1 comprises: a base plate 12 and a face plate 13, and the base plate 12 and the face plate 13 are detachably connected, so that it is convenient to install the meshing mechanism 2, the blades 3 and the swinging member 4. The base plate 12 is provided with a convex ring 121, and the convex ring 121 has a circular groove 122. The ring gear 21 is rotatably arranged on the surface of the convex ring 121, and each gear 22 is rotatably arranged in the circular groove 122. The base plate 12 and the face plate 13 are provided with mounting holes for the positioning shafts of the gears 22, so that the gears 22 have a positioning function, which can effectively ensure the stability of the ring gear 21 being rotatably installed on the convex ring 121. The face plate 13 is provided with a pressing ring 14, and each blade 3 is arranged between the pressing ring 14 and the face plate 13, and each blade 3 is rotatably connected to the pressing ring 14 and the face plate 13, so that there is no interference between each blade 3 and the gear 22, and the pressing ring 14 has a display window 141 for displaying each blade 3, and the display window 141 is used to display different patterns composed of each blade 3. In this embodiment, the dial 13 can be a watch dial, and the surface of the dial 13 can be designed to display a pattern. In other embodiments, a dial is provided on the upper surface of the dial 13, and a display hole is provided on the dial. The display hole is coaxially arranged with the display window and has the same area, so that the dial can cover the position on the dial 13 except for the display window 141.

[0038] The mounting plate 1 is provided with a fan-shaped groove 131. Specifically, the face plate 13 is provided with a fan-shaped groove 131. The fan-shaped groove 131 is a through groove. The fan-shaped groove 131 is used to provide space for the swinging of the swinging member 4. The swinging member 4 is rotatably arranged on the chassis 12. In this embodiment, the elastic member 5 is a spring, one end of which abuts on the second connecting rod 43, and the other end abuts on the side wall of the fan-shaped groove 131. The spring is used to make the abutting block 44 always abut on the outer peripheral surface of the cam 6. In other embodiments, the elastic member 5 is a torsion spring, which is arranged at the connection between the first connecting rod 42 and the second connecting rod 43. The torsion spring can also make the abutting block 44 always abut on the outer peripheral surface of the cam 6.

[0039] The embodiment of the present application provides a watch, which has an opening and closing structure so that the display pattern of the watch has diversity, and the display pattern does not need to be manually adjusted, so that the display pattern can change continuously, thereby improving the grade of the watch.
