Description

Technical Field

[0001] The present application relates to a display screen, and in particular to a knob-shaped display screen. Background Art

[0002] Fitness equipment is usually equipped with a display screen for display and adjustment functions. For example, our company's authorized patent CN219879025U discloses an intelligent resistance adjustment station, CN218529674U discloses a spinning bike with a magnetic resistance device, and CN218010844U discloses a treadmill with a display function. The display screen uses a knob structure, which can be rotated and pressed (or rotated alone) to switch functions and display corresponding data. However, this knob structure is more complicated in order to realize the rotation and pressing (or rotating alone) switching function, and the overall cost is high, and it cannot be made thinner. With the upgrade of wireless communication technologies such as Bluetooth, it is now possible to switch functions by connecting mobile devices through wireless communication, which has some overlap with the physical button operation switching function. In order to reduce the cost of the overall equipment, the cost control of the knob is an indispensable part.

[0003] Therefore, there is a need for a knob-shaped display screen that can maintain a knob-shaped appearance and only needs to display functions. Utility Model Content
