[0023] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0024] like Figures 1 to 5 As shown, a page-turning clock driven by a motor comprises: a base 100, a clock frame 200, a compression spring mechanism, an hour wheel 400, a minute wheel 500, an installation box 600, a driving mechanism and a controller; the base 100 is arranged at one end of the clock frame 200, the installation box 600 is arranged on the clock frame 200, the compression spring mechanism is arranged at one end of the installation box 600 away from the base 100, the hour wheel 400 is rotatably arranged at one side of the installation box 600, and the minute wheel 500 is rotatably arranged at the other side of the installation box 600; the installation box 600 has a cavity 610 inside, the driving mechanism and the controller are both arranged in the installation box 600, the controller is used to control the driving mechanism, and the driving mechanism is used to drive the hour wheel 400 and the minute wheel 500.

[0025] Specifically, the compression spring mechanism includes a compression spring frame 310 and two compression spring bodies 320, the compression spring frame 310 is arranged on the installation box 600, the two compression spring bodies 320 are arranged on one side of the compression spring frame 310, and one of the compression spring bodies 320 abuts against the hour wheel 400, and the other of the compression spring bodies 320 abuts against the minute wheel 500. The hour wheel 400 is provided with 48 evenly distributed hour blades 410, each of which is movably abutted against one of the compression spring bodies 320. The minute wheel 500 is provided with 60 evenly distributed sub-blades 510, each of which is movably abutted against another of the compression spring bodies 320. The driving mechanism connects the hour wheel 400 and the minute wheel 500 through a gear set.

[0026] In the above embodiment, the minute rotating wheel 500 is disposed on the first connecting shaft 950 , and the hour rotating wheel 400 is disposed on the second connecting shaft 960 . The second connecting shaft 960 is provided with a knurling 961 .

[0027] Further, the controller includes a PCB board 810 and a battery box 820, the battery box 820 is connected to the PCB board 810, the battery box 820 is used to hold a battery 821, and the PCB board 810 is used to control the driving mechanism. The PCB board 810 is provided with a single chip computer 811, a power socket 812 and a power cord, the power socket 812 is connected to the battery box 820 through a wire, and the power cord is used to connect to the driving mechanism. The driving mechanism includes a motor body 710, a driving gear 720, a fixed cam 730, a magnet 740 and a sensor 750, the output shaft of the motor body 710 is connected to the driving gear 720, and the other end of the motor body 710 is connected to the fixed cam 730, the magnet 740 is arranged on the fixed cam 730, and the sensor 750 is arranged on the PCB board 810. The sensor 750 is a Hall sensor 750. The motor body 710 is a reduction motor.

[0028] In the above embodiment, the gear group includes a first gear 910, a second gear 920, a third gear 930 and a fourth gear 940. The first gear 910 is rotatably arranged inside the installation box 600, the driving gear 720 is meshed with the first gear 910, the second gear 920 is fixedly arranged on the first connecting shaft 950, the first gear 910 is meshed with the second gear 920, and the second gear 920 is provided with internal teeth inside, the internal teeth are connected to the connecting part 921 through an elastic part, the connecting part 921 is meshed with the third gear 930, the fourth gear 940 is meshed with the knurling 961, and the third gear 930 is meshed with the fourth gear 940. It is worth mentioning that, since the output shaft of the reduction motor is connected to the driving gear 720, that is, the output shaft rotates to drive the driving gear 720 to rotate, and then drives the first gear 910 to rotate, and then the first gear 910 rotates to drive the second gear 920 to rotate, and then the elastic part is driven to rotate through the internal teeth, and the connecting part 921 rotates, so that the third gear 930 rotates, and then the third gear 930 rotates to drive the fourth rotating wheel to rotate, and finally the fourth gear 940 is connected to the knurling 961 to drive the second connecting shaft 960 to rotate. In other words, by setting the second gear 920, the first connecting shaft 950 is driven to rotate, and the second gear 920 is connected to the third gear 930 through the elastic connection and the connecting part 921, which can not only drive the third gear 930 to rotate, but also slow down the rotation speed of the third gear 930, and the third gear 930 is meshed with the fourth gear 940, which further slows down the rotation speed of the fourth gear 940. It is worth mentioning that how to achieve the deceleration effect by meshing and matching between different gears can be realized by existing technology, and no redundant description is given in this embodiment. Therefore, the drive of the motor body 710 enables both the minute wheel 500 and the hour wheel 400 to rotate, and through the cooperation among the first gear 910, the second gear 920, the third gear 930 and the fourth gear 940, the minute wheel 500 and the hour wheel 400 can have different rotation speeds. In other words, through multiple experiments and improvements, the most accurate driving method is finally deployed, which becomes the corresponding rotation rate of the hour wheel 400 and the minute wheel 500, thereby ensuring accurate timing during normal use. That is to say, all sixty blades 510 of the minute wheel 500 rotate one circle, and the hour wheel 400 rotates one hour blade 410. It is worth mentioning that for each hour blade 410 on the hour wheel 400, the back side of the previous hour blade 410 and the front side of the next hour blade 410 will form a number from 00 to 23. Similarly, for each hour blade 510 on the minute wheel 500, the back side of the previous hour blade 510 and the front side of the next hour blade 410 will form a number from 00 to 59.It is worth mentioning that since two compression spring bodies 320 are provided, when the hour wheel 400 or the minute wheel 500 rotates, the compression spring body 320 can well abut and block the hour blade 410 or the minute blade 510, that is, if there is no motor body 710 to provide power for rotation, the hour blade 410 or the minute blade 510 can be blocked by the compression spring body 320, which can well ensure that the hour blade 410 or the minute blade 510 that has not yet rotated to the bottom will not fall down.

[0029] In one embodiment, since the battery box 820 is connected to the PCB board 810, that is, the battery 821 supplies power to the PCB board 810, and then supplies power to the driving mechanism. Specifically, the single-chip microcomputer 811 on the PCB board 810 supplies power to the motor body 710, and the tail shaft of the motor body 710 rotates to drive the fixed cam 730 to rotate synchronously. The magnet 740 on the fixed cam 730 will pass through the Hall sensor 750 once every rotation. The Hall sensor 750 senses the signal and sends it to the single-chip microcomputer 811 on the PCB board 810. The single-chip microcomputer 811 determines the number of rotations of the tail shaft of the motor body 710 by the number of received signals. Since the tail shaft of the motor body 710 and the head shaft of the motor body 710 have a reduction ratio of 171, the single-chip microcomputer 811 controls the number of rotations of the tail shaft of the motor body 710 to control the rotation angle of the head shaft. The overall structure is simple, easy to assemble, durable, stable and reliable, and has low noise when used.

[0030] In summary, the above-mentioned embodiments are not limitative embodiments of the present invention, and any modifications or equivalent variations made by those skilled in the art on the basis of the essential contents of the present invention are within the technical scope of the present invention.
