Description

Child teaching clock and control method thereof Technical Field The invention relates to the field of education teaching aids, in particular to a clock for children teaching and a control method thereof. Background Existing child teaching clocks typically use a simple paper or plastic disk surface, relying on a fixed pointer or digital display to help the child recognize time. However, these conventional teaching clocks lack sufficient interactivity, are not effective for stimulating the interest of children, and the driving structure of the conventional mechanical hands is not able to withstand frequent manual pulling, which easily results in damage to the internal motor or gears. In the prior art, there are few teaching clocks combining an electronic light band and an anti-reversing mechanism, and there is also a lack of a device capable of automatically separating from a motor drive when a pointer is manually dialed. More importantly, the teaching mode of the existing product is hard, mostly fixed voice broadcasting is achieved, the explanation content cannot be flexibly adjusted according to the cognitive level and the questioning of the children, the 'why is the time' is difficult to deeply explain, and the personalized teaching requirement cannot be met. Therefore, there is a need for a child teaching clock and control method that incorporates large language model capabilities, and that combines high interactivity with structural durability. Disclosure of Invention In order to overcome the defects of the existing children teaching clock, the invention provides the clock for children teaching and the control method thereof, the clock combines the traditional pointer with the electronic lamp belt display, and an automatic clutch device is adopted, so that when a user manually dials the pointer, a motor and a gear set can be automatically separated, and the reverse driving of the motor is avoided. Meanwhile, the system actively drives the clock to move to the correct time through the control circuit and interacts with a user through the lamp strip. The clock is suitable for children to learn the time concept, and improves the interactivity and the interestingness of education. The invention aims to provide a child teaching clock and a control method thereof, which have the functions of strong interactivity, durable structure and motor damage prevention. Through combining traditional mechanical pointer and electronic lamp area, adopt automatic separation and reunion mechanism to introduce big language model, explain the time concept with vivid interesting mode, reinforcing the educational and the recreational of clock, help children to understand the time better.
