This invention belongs to the field of electromagnetic interference (EMI) suppression technology, and proposes an EMI suppression device using isolated grounding. It includes shielded modules that act as interference sources or receivers for each other, and a shielded transmission circuit for signal transmission. The shielded modules include camera mechanisms, modules that easily generate high-frequency signals, and modules that easily generate large currents. The shielded transmission circuit includes transmission cables connecting each shielded module. This device is simple, easy to implement, and easy to operate. It mainly utilizes the conductivity of metallic materials to transmit external electromagnetic interference, which is easily received by the shielded modules and the transmission circuit cables, to the ground through a conductive layer. Simultaneously, the transmitted circuit signals are also protected, thus preventing electromagnetic interference to the shielded modules and the transmission circuit cables, allowing the equipment to maintain normal operation.

This application provides a motor-driven rotating mirror assembly and a rotating lidar. The motor-driven rotating mirror assembly includes: a lens frame; a transmitting lens, a receiving lens, and a reflector, respectively fixedly mounted in a transmitting lens mounting hole, a receiving lens mounting hole, and a reflector mounting hole on the base of the lens frame; a transmitting circuit board and a receiving circuit board fixedly connected to the side of the base opposite to the side where the reflector mounting hole is located; a first through hole between the transmitting circuit board and the transmitting lens, and a second through hole between the receiving circuit board and the receiving lens; a rotating reflective structure, which is a straight or regular prism structure with reflective function on all sides; a rotating baffle that divides the rotating reflective structure into transmitting and receiving parts; a rotating mirror motor fixedly mounted in a motor mounting hole at one end of the rotating reflective structure and fixedly connected to the inner side of one side of the lens frame; and a rotating mirror motor drive circuit board fixedly mounted on the outer side of one side of the lens frame.
