This invention discloses a surgical field gimbal imaging device and method, relating to the field of medical auxiliary devices. The device includes a mounting base, a fixed column fixedly connected to one side of the mounting base, a columnar connecting groove on the side of the fixed column away from the mounting base, a connecting column inserted into the columnar connecting groove, and a connecting seat fixedly connected to the side of the connecting column away from the mounting base. A camera body is mounted on the other side of the connecting seat via a multi-directional rotation mechanism. Multiple limiting mechanisms are also included, used to limit the connection between the fixed column and the connecting column. Each limiting mechanism includes an L-shaped frame fixedly connected to the side wall of the fixed column. Compared to traditional imaging devices and head-mounted supports directly connected via multiple screws, this solution uses a connecting seat at the connection point. The connecting seat and the imaging device employ a simpler, detachable connection method, facilitating disassembly, inspection, and maintenance of the imaging device.

The energy meter includes a meter box containing a control panel and a relay. A wiring plate is embedded in the end face of the meter box. A through hole is formed in the center of the front of the wiring plate, and wire holes are formed at both ends of the front of the wiring plate. A conical protrusion is movably fitted inside the through hole, and a main rod is fixedly connected to the outer end face of the conical protrusion. This invention overcomes the shortcomings of existing technologies, achieving efficient wiring, stable conductivity, precise clamping, and quick assembly and disassembly. It solves the problems of complex wiring, poor contact, inconvenient maintenance, and low safety in traditional energy meters, and has high social value and application prospects.

This application provides a high-side NMOS driving circuit and electronic device. The circuit includes a charging power supply module for outputting a charging voltage independent of the main circuit voltage to a bootstrap capacitor module; a lift power supply module for outputting the main circuit voltage to the bootstrap capacitor module; a lift control module for controlling the voltage rise of the bootstrap capacitor module; and a bootstrap capacitor module for outputting a driving voltage to the gate of the NMOS transistor during the voltage rise. During the charging phase, the bootstrap capacitor module is charged to the charging voltage via the charging power supply module. During the lift phase, the bootstrap capacitor module, through the lift power supply module and the lift control module, raises the capacitor voltage to the superposition of the main circuit voltage and the charging voltage to drive the NMOS transistor to conduct. This circuit can still achieve stable NMOS transistor conduction even in scenarios with a wide main circuit power supply voltage range.

This invention discloses a stepper motor frame assembly, including a frame structure, an upper electrode plate, and a middle electrode plate assembly. The upper electrode plate has an annular first electrode plate body and an integrally formed first electrode claw, which is bent from the first electrode plate body and extends axially. The middle electrode plate assembly includes a stacked second electrode plate body and a third electrode plate body, each having a second electrode claw and a third electrode claw arranged opposite to each other, both embedded in the inner wall of the rotor space. The frame structure includes a first frame, a second frame, and a third frame, which are injection molded together with the middle electrode plate assembly. The first frame and the second frame cooperate to form a first winding space and a first rotor cavity, and the second frame and the third frame cooperate to form a second winding space and a second rotor cavity. Each space and cavity has a common central axis. This invention solves the problems of complexity and difficult assembly of existing stepper motor frame assemblies, realizes the integrated design of the electrode plate and the frame, and improves the performance and reliability of the motor.
