DEVICE COMPRISING BODY AND SHOCK ABSORBER, AND ROBOTIC VACUUM CLEANER COMPRISING SUCH DEVICE Russian patent published in 2013 - IPC G05D1/02 

FIELD: information technologies.

SUBSTANCE: device (1, 21), comprising at least a body (2, 22) and a shock absorber (6), which is movably connected to the body to protect the body against shock caused by collision with an obstacle in process of device movement on the surface, in which the shock absorber (6) is fixed to the body (2, 22) by means of at least one spring (9, 25), which stretches in direction, which is at least mainly perpendicular to the direction, in which the shock absorber is movable relative to the body, differing by the fact that the spring (9, 25) is a pre-stressed tensioned spiral spring, operating for tension. At the same time the spring (9, 25) has relatively high stiffness at forces below the specified value and relatively low stiffness at forces above the specified value. Besides, the robotic vacuum cleaner is made, comprising such a device.

EFFECT: protection of a body against shock caused by collision with an obstacle in process of device displacement on surface.
