Description

Technical Field

[0001] The utility model relates to the technical field of smart watches, in particular to a dial structure with a magnetic encoder and a smart watch. Background Technique

[0002] Smart watches have information processing capabilities and meet the basic technical requirements of watches. In particular, in order to make smart watches more high-end and provide a better experience, physical hands are retained in smart watches and can be used as traditional watches when the system is not awakened.

[0003] Generally, the rotation detection of the physical hands of a smart watch mainly relies on a mechanical encoder. However, the mechanical encoder occupies a large volume and has a low recognition accuracy for the rotation angle. Therefore, an optical encoder is now more commonly used instead of a mechanical encoder. For example, the utility model patent application with the application number 202320776214.2 discloses a crown detection device for a smart watch, which uses an optical detection module to detect the rotation of the watch shaft on the crown, that is, uses an optical encoder to detect the rotation of the physical hands, ensuring the detection accuracy well. Another example is the invention patent application with the application number 201410226060.5, which discloses a control knob for a smart watch, specifically including a knob head for installation on the outer side of the watch case and a connecting rod and an optical encoder for installation inside the watch case, ensuring the recognition accuracy well. However, the optical encoder is highly sensitive to light and dust and is difficult to meet the use in more complex scenarios. Especially for outdoor watches that are exposed to dust and water vapor in environments such as outdoors or diving, the problem is more serious, and the durability is poor, requiring maintenance.
