Technical Examples

A knob structure is disposed on an electronic device to input a preset control signal. The knob structure includes a rotary encoder, a brake wheel, and a rotary wheel. A plurality of ratchets is disposed around the circumference of the brake wheel and locked on the rotary encoder. The rotary wheel is rotatably disposed on the body case of the electronic device and is nested on the brake wheel correspondingly. A block is disposed on the rotary wheel to be embedded between the ratchets, so as to control the rotation of the rotary wheel to generate a preset control signal by causing the brake wheel to drive the rotary encoder to rotate. The rotary wheel and the brake wheel are engaged non-fixedly, so as to prevent the rotary wheel and the body case of the electronic device from interfering with each other.
