However, this method requires a winding frame, and since the winding frame has a relatively long mold opening period, a fixed structural height and a large body size, the structure design of other newly developed models is limited, and the design cannot be made thinner.

The utility model provides a signal transmission mechanism, a laser ranging device and a mobile robot for solving the technical problems. The mobile robot comprises a body and a laser ranging device. The laser ranging device is arranged on the machine body.
