Mounting bracket and self-propelled robot

A self-propelled robot, comprising a base body and a laser distance sensor, and further comprising:

• a mounting bracket, configured to rotatably mount the laser distance sensor on the base body;
• wherein the mounting bracket comprises:
• a housing, which is provided with an inner cavity;
• a rotating shaft, vertically arranged, and configured to rotate about an axis, in the inner cavity;
• and
• a magnetic positioning assembly, comprising a first magnetic element and a second magnetic element which are respectively attached to the housing and the rotating shaft;
• wherein the laser distance sensor is attached to the rotating shaft;
• and wherein the mounting bracket is configured to prevent the rotating shaft from deviating from the axis by generating a force between the first magnetic element and the second magnetic element in a radial direction of the rotating shaft,
• wherein the mounting bracket is mounted on the base body via the housing.
