The present application relates to the technical field of robot motion control, and in particular to a complex space boundary control method and system for orthopedic surgery robot, and an electronic device. The method comprises obtaining a target desired position of a spherical center of a target drill ball head installed on a robot operating end, complex space boundary data, and a radius of the target drill ball head; the complex space boundary data is a closed manifold polyhedron of triangular facet envelopes; it is judged whether the target desired position is located outside the complex space boundary, and according to the judgment result, it is judged whether the target desired position is corrected according to the radius of the target drill ball head to obtain a safe desired position of the spherical center of the target drill ball head; the complex space boundary control method can dynamically compensate the radius of the high-speed drill ball head, and solves the problem that in the prior art, for drill tools with different ball head radii, different size compensation boundary models need to be generated in advance, and dynamic management / switching of the models needs to be performed.

This invention provides a class of short-wavelength light-converting materials based on benzoxazole, with the structure shown in Formula I, where R1 and R2 are each independently hydrogen atoms, C1-C18 straight-chain or branched alkyl groups; and R3 is an aryl group or a substituted aryl group. The short-wavelength light-converting material of this invention possesses advantages such as excellent short-wavelength ultraviolet light absorption, high luminous quantum efficiency, good photostability, low cost, and ease of mass production. When doped at a certain concentration into the encapsulating film of solar cells, it can efficiently absorb short-wavelength ultraviolet light to avoid UVID (ultraviolet-induced power degradation), and convert the absorbed short-wavelength ultraviolet light into long-wavelength ultraviolet or blue-violet light that can be efficiently utilized by solar cells, thereby increasing power generation. This is of great significance for improving the overall performance and economic benefits of photovoltaic modules.

This utility model belongs to the field of lightning protection technology, specifically relating to a power supply lightning protection box, including a box body with a cavity at the top. The cavity has a first terminal and a second terminal. The second terminal is connected to a varistor via a wire. The varistor is connected to an electromagnet and a telescopic metal rod inside a switching device. A magnetic block is fixedly connected to a long block, and a spring is mounted on the long block. The electromagnet is also connected to the first terminal via a wire. When the power supply is energized, the telescopic metal rod inside the cavity discharges. When lightning strikes the metal rod, current flows from the metal rod through the varistor. The extremely high lightning voltage causes the varistor to become extremely resistant, causing the electromagnet in the switching device to lose current. The spring then resets, causing the long block to press the stop button, thus shutting off the power supply. This novel design has a simple structure, strong protection, and the cavity and slot cover facilitate disassembly and maintenance.
