The invention discloses a rotor suspension driving structure and method and a motor, and belongs to the technical field of magnetic suspension drive.The rotor suspension driving structure comprises a rotor suspension assembly and a rotor rotation driving assembly which are arranged on the two radial sides of a rotor, and working air gaps are formed between the rotor suspension assembly and the rotor rotation driving assembly and the rotor; the rotor is made of diamagnetic materials, the rotor suspension assembly below the rotor adopts a permanent magnet array and can be arranged in an Opposite or Halbach mode, passive and stable suspension support is provided for the rotor through magnetic repulsive force, the ratio of the suspension force to the gravity of the rotor is increased along with reduction of the scale, the miniature design of the bearing can be achieved, meanwhile, extra space is not occupied, and the bearing is more compact in structure and more compact in structure. And the size requirement of the motor can be further reduced.

This invention discloses a water surface cleaner, comprising a floating cleaner body, a drive mechanism, and a filter mechanism installed on the cleaner body; the drive mechanism is used to drive the cleaner body to move on the water surface; the filter mechanism is used to filter the water flow. The water surface cleaner of this invention can clean floating debris on the water surface, effectively replacing manual retrieval operations and improving cleaning efficiency.

The application discloses a kind of side edge segmented metal edge-wrapping circuit board and processing method thereof, belong to circuit board metal edge-wrapping field, the method includes: overall edge-wrapping is carried out to the side edge of circuit board, vertical segmentation is carried out by drilling and milling;The parameters of T-shaped cutter are determined, and T-shaped cutter is made;Depth control milling is carried out along the side wall of edge-wrapping by T-shaped cutter to form horizontal segmentation.The T-shaped cutter specifically includes: shank, one end of the shank is fixedly connected with blade, and the end of the blade away from the shank is fixedly connected with a plurality of evenly distributed blade tips, the material of the T-shaped cutter is tungsten steel, and the blade tip of the T-shaped cutter is staggered three-edged.The application carries out vertical segmentation by drilling and milling after conventional overall edge-wrapping, then forms horizontal segmentation by special T-shaped cutter and specific parameters, and the circuit board with side wall metal edge-wrapping segmented in vertical and horizontal directions can be formed by such combination.

The invention relates to the technical field of lithium batteries, and discloses a double-doped fluorinated lithium aluminum phosphate solid electrolyte material and a coating diaphragm. Specifically, the structural general formula of the double-doped fluorinated lithium aluminum phosphate solid electrolyte material is Li < 1-2x > Al < 1-x > Zr < x > Zn < 0.5 x > PO < 4 > F, and x is more than or equal to 0.05 and less than or equal to 0.15. According to the invention, Zr < 4 + > and Zn < 2 + > double doping realizes double effects of channel expansion and interface stabilization through element synergy, the solid electrolyte material is used for preparing a coating diaphragm, the prepared diaphragm has high ionic conductivity and excellent lithium metal compatibility, and the water-based solvent slurry is adopted for coating, no organic solvent is used, and the solid electrolyte material is safe and environment-friendly.
