摘要： A self-propelled cleaning apparatus, comprising a main body (7), a cleaning device and a lifting device, wherein the cleaning device is connected to the main body (7) by means of the lifting device. The lifting device comprises a synchronous linkage assembly (1), a link rod mechanism (2) and a driving part (3), wherein the link rod mechanism (2) comprises a first link rod (201) and a second link rod (202), the first link rod (201) and the second link rod (202) are rotatably connected to the main body (7) around an axis in a horizontal direction, and the first link rod (201) is rotatably connected to the second link rod (202) by means of the synchronous linkage assembly (1); and the driving part (3) is used for driving the first link rod (201) so that the cleaning device can ascend or descend relative to the main body (7). Thus, the driving part (3) drives the first link rod (201) to rotate so that the cleaning device can ascend or descend relative to the main body (7), and therefore the space occupied by the lifting device in a vertical direction can be reduced, thereby reducing the size of the self-propelled cleaning apparatus, and facilitating the miniaturization of the self-propelled cleaning apparatus.

摘要： A laser ranging device (1) and a robot. The laser ranging device (1) comprises a transmitting unit (11) and a receiving unit (12). The transmitting unit (11) comprises a transmitter (111) that is used for transmitting a pulsed laser to a target object to undergo ranging and a transmitting lens (113) that is used for allowing the transmitted. pulsed laser to pass through. The receiving unit (12) comprises a light detector (121) that is used for receiving the pulsed laser reflected from the target object and a receiving lens (123) that is used for the reflected pulsed laser to pass through. The light detector (121) is disposed by means of being encapsulated in an encapsulating module (124), the encapsulating module (124) being located behind the receiving lens (123) and opposite the receiving lens (123), and one side thereof facing the receiving lens (123) being constructed as an extinction surface.

摘要： An installation support and an autonomous mobile robot. The installation support comprises a shell, a rotating shaft (200), and a magnetic positioning assembly. The shell has an inner cavity (130). The rotating shaft (200) is vertically arranged and rotatably provided in the inner cavity (130). The magnetic positioning assembly comprises a first magnetic element (420) and a second magnetic element (410). The first magnetic element (420) and the second magnetic element (410) are provided on the shell and the rotating shaft (200), respectively. A laser distance sensor is provided on the rotating shaft (200). Accordingly, when the rotating shaft (200) deviates from the axis, the installation support is configured to position the relative location of the rotating shaft (200) and the shell by means of a force which is generated between the first magnetic element (420) and the second magnetic element (410) and takes the direction as the radial direction of the rotating shaft (200). The installation support can position the relative location of the rotating shaft (200) and the shell by means of the force in the radial direction of the rotating shaft (200), so that the phenomena of eccentricity and shaking of the laser distance sensor during rotation are effectively relieved, and the reliability, the service life, the precision and the like of a product are improved.
