Abstract: A cleaning machine includes a body having a first surface and a second surface opposite to the first surface, a laser module mounted on the first surface of the body and having a transmitting terminal and a receiving terminal, a rotary table mounted on the first surface of the body and rotating about the laser module. Further comprising a reflecting portion connected with the rotary table, the reflecting portion along with the rotary table rotates collectively about the laser module. The transmitting terminal of the laser module emits a light signal, the reflecting portion reflects the light signal out of the body, the receiving terminal receives the light signal reflected by an obstacle.

Abstract: A pivot mechanism rotatably coupes a cover to a base of a foldable electronic device. The pivot mechanism includes a connector, a first rotation assembly, and a second rotation assembly. The first rotation assembly is rotatably coupled to the base and fixedly attached to the connector. The second rotation assembly is fixedly coupled to the cover and rotatably coupled to the connector. The first rotation assembly rotates relative to the base and the second rotation assembly remains fixed relative to the connector as the cover is rotated open to a first angle. The second rotation assembly rotates relative to the connector as the cover is rotated further to a second angle.

Abstract: An electronic device comprises a main body, a plurality of I/O interfaces, and an ejecting apparatus. The ejecting apparatus is mounted on the main body and comprises an enclosure, a supporting member received in the enclosure, a carrier secured on the supporting member to support the I/O interfaces, a first driving unit, and a second driving unit. The first driving unit drives the carrier to slide along a first direction, and the second driving unit drives the carrier to slide along a second direction opposite to the first direction. When the I/O interfaces are exposed out of the enclosure, the first force is larger than the second force. When the carrier is operated to slide to a position where the second force is larger than the first force, the I/O interfaces are driven to be received in the enclosure.
