[0019] Please see Figure 1 The same frequency gearbox of the array clock includes pointer wheel A 1 and pointer wheel B 2, with the drive gear system of pointer wheel A and the drive gear system of pointer wheel B arranged symmetrically on the left and right.
[0020] The drive gear system of the A-pointer wheel includes: an A-stator plate 11, an A-pointer support coil assembly 12, an A-magnetic wheel assembly 13, an A-fourth wheel 14, an A-threeth wheel 15, and an A-twoth wheel 16.

The A-threeth wheel 15 is meshed with the A-twoth wheel 16. The A-twoth wheel 16 is meshed with the A-pointer wheel.
[0021] The drive gear system of the B pointer wheel includes: B stator plate 21, B pointer support coil assembly 22, B magnetic wheel assembly 23, B four-wheel 24, B three-wheel 25, and B two-wheel 26. The B stator plate 21 is connected to the B four-wheel 24 through the end of the B magnetic wheel assembly 23. The B four-wheel 24 is connected to the B three-wheel 25. The B three-wheel 25 is connected to the B two-wheel 26. The B two-wheel 26 is connected to the B pointer wheel 1. The minimum step angle driven by the drive gear system of the A pointer wheel 1 and the drive gear system of the B pointer wheel is the same.
[0022] Among them, the drive gear system of pointer wheel A and the drive motor of pointer wheel B are the same.
[0023] The drive gear system of pointer wheel A and pointer wheel B also includes a support structure. The support structure includes an upper clamping plate 31, a middle clamping plate 32 and a lower clamping plate 33. The installation space formed between the upper clamping plate 31 and the lower clamping plate 33 provides installation and rotation space for each gear system component. The middle clamping plate 32 divides the gear system into upper and lower parts. The upper part is pointer wheel A 1 and pointer wheel B 2, and the lower part is four wheels A 14, three wheels A 15, two wheels A 16, four wheels B 24, three wheels B 25 and two wheels B 26, which are arranged in an orderly manner on the left and right sides.
[0024] Wherein: A pointer wheel 1 and B pointer wheel 2 are respectively a combination of hour / minute hands, or a combination of hour / second hands, or a combination of array clocks.
[0025] This utility model may also include a C pointer wheel, which has the same gear system as the drive gear system of the A pointer wheel and the drive gear system of the B pointer wheel, and the minimum step angle of the drive gear system is the same.
[0026] Furthermore, the A-wheel 1, B-wheel 2, and C-wheel are combinations of hour / minute / second hands, or combinations of hour / minute hands + multi-function hands, or combinations of array clocks. This not only ensures normal meshing and transmission between the wheel trains, but also further optimizes space utilization, helps maintain the overall compactness and stability of the movement, and ensures the accuracy of timekeeping.
[0027] Among them, such as Figure 2 As shown: It also includes a circuit board 50 that connects the A pointer support coil assembly 12, the B pointer support coil assembly 22, and the optical sensing system 40. The circuit board 50 has a standard port 51. The standard interface 51 includes a first connection port 511 of the second pointer support coil assembly 12, a second connection port 512 of the second pointer support coil assembly 22, and a third connection port of the optical sensing system 40 (not shown in the figure).
[0028] The optical sensing system 40 includes a light emitter and a receiver, which are not shown in the figure.
[0029] The transmission principle is as follows: When wheels A (14) and B (24) rotate synchronously, one side of wheel A (14) meshes with wheel A (15). According to the gear meshing transmission principle, the rotation of wheel A (14) drives wheel A (15) to rotate synchronously, and the rotation of wheel A (15) drives wheel A (16) to rotate synchronously. Wheel A (16) meshes with wheel A (1), thus transmitting power to wheel A (1), which rotates accordingly. Simultaneously, wheels B (24) and B (25) are related; the rotation of wheel B (25) drives wheel B (26) to rotate synchronously. Wheel B (26) meshes with wheel B (2), thus transmitting power to wheel B (2), which rotates accordingly. This sequential transmission of power ensures that wheels A (1) and B (2) have the same step angle and rotate according to a certain transmission ratio, corresponding to the movement speed of the minute and hour hands respectively, achieving the timekeeping display of minutes and hours.
[0030] The advantages of this utility model, which combines modules, are as follows:
[0031] 1. The pointers of pointer wheels A (1), B (2), and C (3) have the same minimum step angle, allowing the three pointers to rotate simultaneously at the same speed, or to rotate in overlapping fashion.
[0032] 2. The same gear train for pointer wheels A, B, and C can effectively save on gearbox and design costs.
