Description
Technical Field
The invention relates to a watch capable of adjusting the position of a pointer, in particular to a watch capable of adjusting a metal pointer to a preset position.
Background
The common quartz watch movement can correctly walk according to the lapse of time and step by step as long as a battery is correctly arranged for supplying power, and is not controlled and influenced by the outside; along with the rise of the intelligent wearable watch, a novel gear box core appears, and the biggest difference between the novel gear box core and a common quartz core is that the needle movement of the novel gear box core needs time sequence control provided by an external circuit. The gear box motor movement is mainly a mechanical component, and an internal electronic part only provides identification time sequence and drives the pointer to rotate without a pointer position memory function or a feedback function; in practical use, the situation that the position of the pointer needs to be calibrated is often encountered, and therefore, a certain sensing device needs to be arranged outside, and a corresponding electronic circuit is added to complete the detection principle.
Capacitive touch is very widely used, and can identify a human finger because a human body and a touch panel constitute a capacitor, and in fact, a metal conductor in a certain distance range can also produce the same effect. In actual use, the metal shell causes false touch under the condition of improper treatment often occurs.
In CN2017114278410 and CN2017114278302, the above-mentioned side effect of a false touch of a capacitive touch is fully utilized, so that the monitoring and adjustment of the position of the metal pointer are realized. In the above two applications, the position of the pointer is determined by using a loop monitoring method, and at this time, a specific loop state needs to be specially set for the pointer and the capacitive touch pad to achieve detection. Further, when a plurality of pointers are simultaneously positioned right above the capacitive touch block, the pointers need to be moved to places other than the capacitive touch block by extra work.
