Description

Smart watch and its control knob

technical field

The invention relates to a smart watch and a control knob thereof.

Background technique

The button of a traditional mechanical watch is generally installed at the 3 o'clock position of the watch case, and is connected to the movement through a connecting rod. There are two specific operations, one is to pull out the button and rotate it up or down, and the other is to press the button up or down Rotate, so that the user can realize the operation function of the watch through mechanical transmission. However, the mechanical transmission of traditional mechanical watches cannot be converted into digital signals, thus making it impossible to operate smart watches (digital watches).

Existing smart watches widely use switch buttons (buttons), usually each button switch has two pairs of contacts, each pair of contacts is composed of a normally open contact and a normally closed contact, when the button is pressed, the two pairs The contacts act at the same time, the normally closed contacts are opened, and the normally open contacts are closed. Push button switches are used to manually send control signals to control contactors, relays, electromagnetic starters, etc., and can complete basic controls such as start, stop, forward and reverse, variable speed, and interlock. In order to meet the needs of multiple operating functions, smart watches will be equipped with multiple switch buttons, and some smart watches even have 6 buttons, resulting in inconvenient use and complex appearance of the watch. In addition, there are buttons such as touch screen switches, which consume a lot of power and have a great negative impact on battery life.
