Abstract: This application provides a camera lens, a camera apparatus, and an electronic device. Lenses of an optical system of the camera lens are divided into two groups, and focusing of the optical system is implemented by moving one group of lenses. In this way, high imaging quality of a primary camera lens in a case in which a focus distance is infinity can be ensured and imaging quality in a case in which the focus distance is a macro distance can be improved without adding an additional wide-angle lens or a dedicated macro lens and without increasing surface process complexity and manufacturing difficulty of the primary camera lens.

Abstract: A seafloor observation network-based subsurface buoy device with real-time power supplying and high-speed data transmitting is provided. The subsurface buoy device includes a seabed base deployed on the seafloor and a vertical mooring system connected to a bottom surface of the seabed base to extend to the sea surface. The seabed base serves as a gravity anchor to enable the subsurface buoy device to be positioned stably at a layout site, and is further used for obtaining power supply of the subsurface buoy device from a junction box of a seafloor observation network. The seabed base also sends the management and control commands from the junction box to the vertical mooring system, and transmits the data collected by the vertical mooring system back to the junction box in real time.

Abstract: An actuator includes a motor, a transmission mechanism, a clutch mechanism, and an output shaft. The motor is connected to the clutch mechanism in a transmission manner through the transmission mechanism. The clutch mechanism is connected to the output shaft. The transmission mechanism is power-coupled to the output shaft by using the clutch mechanism when the motor drives the output shaft to rotate. The transmission mechanism is power-decoupled from the output shaft by using the clutch mechanism when an external force drives the output shaft to rotate. The charging port cover including the foregoing actuator has a function of preventing the charging port cover from being opened by mistake. A user needs to apply an external force to manually open the charging port cover when the motor fails and the charging port cover cannot be normally opened, to effectively prevent the charging port cover from being opened by mistake.
