TECHNICAL FIELD

[0001] The application relates to the technical field of electric wave clock mechanisms, in particular to an electric wave clock mechanism with super-strong credit and fast memory time calling. BACKGROUND

[0002] The electric wave clock mechanism is a device for automatically calibrating the running time of a clock through receiving the standard time signal transmitted by the national time center in the form of long-wave radio, and automatically keeping the time displayed by the electric wave clock in precise synchronization with the standard time kept by the country after decoding and processing by the built-in microprocessor.

[0003] There are two types of electric wave clock mechanisms in the prior art:

[0004] Small-size square mechanism (56mm x 56mm): due to the compact layout, the antenna size is small and close to the metal parts, resulting in poor receiving performance, low sensitivity, long signal receiving time and high power consumption.

[0005] Large-size special-shaped mechanism (such as T-shaped): although a high-performance antenna can be installed, the shell mold needs to be customized, resulting in high cost, high price of finished products and weak market competitiveness.

[0006] Both the above two types of mechanisms have the problem of difficult balance between receiving performance and cost, and a solution that can maintain compact size and improve receiving sensitivity is urgently needed. CONTENT OF THE INVENTION

Finally, through the cooperative control of the first and second stepping motors and the gear set, the effect of precise time can be realized.
