The utility model discloses a single edge axle outer rotor wheel hub motor light weight motor box belongs to motor box technical field. The utility model discloses through optimizing motor box structure design and processing technology, realizes the light weight of motor box and the strength promotion. Specifically, the utility model will motor magnetism steel ring, aluminium package magnetism ring and motor box body are integrally formed through die casting or casting process. Among them, motor magnetism steel ring adopts the L type structure of precision machining, local optimization thickness, to satisfy magnetism demand and reduce weight, simultaneously, adopts local thickening design at the connecting part of motor box and motor end cover, has promoted the connecting strength and structural stability. The utility model discloses through the integration manufacturing, has reduced the assembly link, has improved production efficiency and product consistency, has effectively solved the problem that traditional wheel hub motor box is heavy, and the connecting strength is insufficient.

This invention discloses a method for preparing biomass hard carbon anode materials without acid washing, comprising the following steps: using pure water as a solvent, placing biomass particles in a Soxhlet extractor, continuously circulating and extracting the biomass particles under reflux conditions for 2-5 hours; after extraction, removing the solid and drying it to obtain water-extracted purified biomass; heating the obtained water-extracted purified biomass to 300-550°C at a heating rate of 2-10°C / min, holding it at this temperature for 2-5 hours, then naturally cooling it to room temperature, and then washing and drying it with pure water; heating the obtained pre-oxidized carbonized product to 1100-1550°C at a heating rate of 2-10°C / min, holding it at this temperature for 3-6 hours, and then naturally cooling it to room temperature; washing the obtained carbonized product with pure water until the filtrate is neutral, and then drying it. Compared with the prior art, this method solves the problems of serious wastewater pollution, significant safety hazards, high costs, long production cycles, and the easy introduction of oxygen-containing defects that damage electrochemical performance.
