[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0030] From the above description, it can be seen that the beneficial effects of the utility model are:
[0031] The utility model provides a decorative gear mechanism for a wall clock, which adds a power supply, a driving motor and a gear set to the structure of the existing wall clock; the gear set is installed on the clock face of the wall clock; the power supply is electrically connected to the driving motor, the gear set includes a common wheel and at least three groups of transmission wheels respectively connected to the common wheel, and at least three groups of transmission wheels are evenly distributed on the periphery of the common wheel, the transmission wheel can be rotatably installed on the clock face of the wall clock, the driving motor is connected to one group of transmission wheels, so that a group of transmission wheels connected to the driving motor can drive all gear sets to rotate, and through the above-mentioned installation method, the common wheel does not need to be fixed on the clock face of the wall clock, and the common wheel is clamped by at least three groups of transmission wheels, which not only realizes the overall transmission, but also realizes the assembly of the gear set. At the same time, compared with the gear sets that mesh in sequence, this scheme can reduce the output torque requirements of the driving motor and reduce the risk of damage to the gear parts by rationally arranging the gear sets.
[0032] Furthermore, it also includes a relay, a controller and a movement for controlling the drive of the minute hand and the hour hand; the power supply is electrically connected to the drive motor through the relay, the time data output end of the movement and the signal control end of the relay are electrically connected to the controller respectively, and the controller is integrated with a setting end for inputting time data and a memory for storing the time data input by the setting end.
[0033] From the above description, it can be seen that the user can customize the input time through the setting end and store it in the memory. When the controller determines that the time output by the time data output end of the movement is consistent with the time stored in the memory, the control relay is energized and turned on, so that the power supply supplies power to the drive motor to drive the gear set to run, thereby realizing the dynamic display of the clock face. This is especially true for some special groups of people, such as the deaf, who cannot be identified by audio. By using this solution, users can judge whether the timing has been reached by the dynamic changes of the clock face, which serves as a reminder.
[0034] Furthermore, there are three groups of transmission wheels, and the three groups of transmission wheels are distributed at three vertex positions of an equilateral triangle, and each group of transmission wheels consists of two mutually meshing sub-transmission wheels.

[0038] Furthermore, the wall clock is circular, and an annular track is provided along the circumferential side wall of the wall clock, a conductive ring is embedded on the inner side wall of the annular track, the conductive ring is electrically connected to a controller provided inside the wall clock, a light sensor movable along the annular track is installed on the annular track, a conductive terminal is provided on the light sensor, and the conductive terminal is in contact with the conductive ring.
[0039] From the above description, it can be seen that through the above method, the light sensor can move along the circular track and be fixed at any position of the circular track, thereby realizing the adjustable position of the light sensor. At the same time, by adding a conductive ring on the circular track, the conductive terminal of the light sensor maintains contact with the conductive ring, so that the light sensor can be electrically connected to the controller inside the watch case at any position of the circular track. The use of the above structure can overcome the influence of different installation positions of the watch on the light sensor.
[0040] Furthermore, the cross-section of the annular track is in a convex shape, the portion of the light sensor embedded in the annular track is provided with a base adapted thereto, and the conductive terminal is provided on the base.
[0041] It can be seen from the above description that the light sensor and the annular track are assembled by the above method.
[0042] Furthermore, the base is provided with a mounting rod, the mounting rod is provided with a second external thread, the light sensor is provided with a second mounting hole, and the second mounting hole is provided with a second internal thread matched with the second external thread.
[0043] From the above description, it can be seen that through the above structure, the position of the light sensor in the axial direction of the mounting rod can be adjusted, that is, the distance between the light sensor and the annular track can be adjusted. When the light sensor is close to the annular track, it clamps the annular track together with the base to achieve position locking and fixation. When the light sensor is away from the annular track, the position can be adjusted.
[0044] Furthermore, the mounting rod is sleeved on a washer, and the washer is located between the light sensor and the annular track.
[0045] From the above description, it can be seen that adding a gasket can protect the light sensor and avoid excessive wear.
[0046] Furthermore, the conductive terminal is an elastic metal sheet having a protrusion, and the protrusion is used to contact the conductive ring.
[0047] It can be seen from the above description that the elastic metal sheet with a protruding portion is used as a conductive terminal, which has a certain elastic deformation space, and satisfies the electrical connection while being easy to move.
