DETAILED DESCRIPTION

[0032] A second transmission device, which is fixed on one side of the optocoupler PCB board 1;

[0033] A sub-transmission device, which is fixed on the other side of the optical coupling PCB board 1;

[0034] The upper cover 2 is provided with a connecting portion, on which a mounting shaft is fixed, on which a second gear 34, a minute gear 7 and an hour gear 9 are rotatably connected, the second transmission device is drivingly connected to the second gear 34, the minute transmission device is drivingly connected to the minute gear 7, the minute gear 7 is provided with a cross gear 5 for driving the hour gear 9 to rotate, and the second gear 34, the minute gear 7 and the hour gear 9 are all provided with a first light transmission hole 71.

[0035] Furthermore, the outer end of the optical coupling PCB board 1 is connected to a core wiring board 11 .

[0036] Furthermore, the second transmission device comprises:

[0037] Second motor 31; fixed on one side of the optocoupler PCB board 1;

[0038] A second worm 32 connected to the output end of the second motor 31;

[0039] The second transmission gear 33 is drivingly connected to the second worm 32 and is also meshingly connected to the second gear 34 .

[0040] Furthermore, the sub-transmission device comprises:

[0041] The sub-motor 41 is fixed on the other side of the optical coupling PCB board 1;

[0042] A sub-worm gear 42 connected to the output end of the sub-motor 41;

[0043] The sub-transmission gear 43 is drivingly connected to the sub-worm gear 42 and is also meshingly connected to the sub-gear 7 for power.

[0044] Furthermore, the upper cover 2 has a support portion 22 for fixing the second transmission gear 33, the minute transmission gear 43 and the cross gear 5, and the second transmission gear 33, the minute transmission gear 43 and the cross gear 5 are fixed to the support portion 22 through a connecting shaft. The position of the above three in the housing is fixed by passing the connecting shaft through the second transmission gear 33, the minute transmission gear 43 and the cross gear 5 to the support portion 22.

[0045] Furthermore, the second transmission gear 33, the minute transmission gear 43, the minute gear 7 and the cross gear 5 all have a meshing gear portion 10 protruding outward in the middle, the meshing gear portion 10 of the second transmission gear 33 is meshed and connected with the second gear 34, the meshing gear portion 10 of the minute transmission gear 43 is meshed and connected with the minute gear 7, the meshing gear portion 10 of the minute gear 7 is meshed and connected with the cross gear 5, and the meshing gear portion 10 of the cross gear 5 is meshed and connected with the hour gear 9. The transmission between the above gears is driven by the meshing gear portion 10.

[0046] Furthermore, a second optical coupling device 61 and a time-sharing optical coupling device 62 are arranged in parallel on the optical coupling PCB board 1. The second optical coupling device 61 and the time-sharing optical coupling device 62 are concave structures. Both ends of the second optical coupling device 61 and the time-sharing optical coupling device 62 are provided with a second light-transmitting hole 611. The concave part of the second optical coupling device 61 is for the second gear 34 to extend into, and the concave part of the time-sharing optical coupling device 62 is for the minute gear 7 and the hour gear 9 to extend into. One of the second light-transmitting holes 611 of the second optical coupling device 61 and the time-sharing optical coupling device 62 is a light-emitting hole 612.

[0047] First, the clock core is connected to an external device and receives a signal from the external device. In the first step, the second optical coupler is detected. If it is in a conducting state (i.e., the first light-transmitting hole 71 of the second gear 34 coincides with the transmitting and receiving position of the second light-transmitting hole 611 of the second optical coupler device), it is regarded as zero position.

[0048] If it is in the non-conductive state, the second motor 31 drives the second worm 32 to drive the second transmission gear 33 to drive the second gear 34 to rotate, and the first light-transmitting hole 71 of the second gear 34 coincides with the transmitting and receiving position of the second light-transmitting hole 611 of the second photocoupler device (the light-emitting hole 612 transmits through the first light-transmitting hole 71 and then passes through the second light-transmitting hole 611 on the other side). When it is in the conductive state, the second motor 31 stops rotating, and the second returns to 0 at this time.

[0049] The second step refers to the first step, the split photocoupler is tested, if it is in the conducting state (that is, the first light-transmitting hole 71 of the split gear 7 and the hour gear 9 coincides with the transmitting and receiving position of the second light-transmitting hole 611 of the split photocoupler device), it is regarded as zero position;

[0050] If it is in the non-conducting state, the sub-motor 41 drives the sub-worm 42 to drive the sub-transmission gear 43 to drive the sub-gear 7 to rotate, the sub-gear 7 drives the cross gear 5, and the cross gear 5 drives the hour gear 9, so that the first light-transmitting hole 71 of the sub-gear 7 and the hour gear 9 coincides with the transmitting and receiving position of the second light-transmitting hole 611 of the sharing photocoupler device (the light-emitting hole 612 emits through the first light-transmitting hole 71 and then passes through the second light-transmitting hole 611 on the other side), that is, when it is in the conducting state, the sub-motor 41 stops rotating, and the time-sharing is returned to 0 at this time.

[0051] The third step is to reset the hours, minutes and seconds to zero and then drive the motor to adjust the time according to the instructions of the external device and start normal work.

[0052] The rotation ratio of the minute gear 7 and the hour gear 9 is 12:1.

[0053] The minute motor 41 and the second motor 31 can rotate forward and reverse to control the movement to adjust the time, greatly shortening the time of adjusting the time.

[0054] At the same time, when the gear 9 rotates 12 circles and reaches the detection point, a detection can be triggered and the above-mentioned first and second steps are repeated.

[0055] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0056] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
