The present invention discloses a torsion support structure of an intelligent electric vehicle, including a front fork, wherein the end of the front fork is provided with two left and right fork openings, the fork openings are provided with forks, the inner side and / or outer side of the fork openings are provided with torque support gasket grooves, the torque support gasket grooves are provided with corresponding torque support gaskets, the torque support gaskets are eccentric structures or any non-rotating structures, and the strength of the torque support gaskets is greater than the strength of the fork openings; the torque support gaskets are provided with closed flat square holes or open flat square grooves, and the flat square part of the motor shaft cooperates with the closed flat square holes or the open flat square grooves. The torque support gasket of the present invention shares the torque of the motor shaft, greatly reduces the damage to the fork openings of the front fork, prevents the front wheel motor from falling off after the fork openings of the front fork are deformed, and improves the safety performance of the electric vehicle.

The invention provides a wound repair membrane and a preparation method and application thereof, according to the method, a spongy membrane dressing is formed by utilizing the cross-linking effect of sodium hyaluronate, curcumin, arginine and zinc ions, it is proved through infrared rays that sodium hyaluronate, curcumin, arginine and zinc ions are successfully cross-linked together, and a novel hyaluronic acid polysaccharide polymer material is obtained. Besides, a spongy membrane dressing is formed by utilizing the crosslinking effect of sodium hyaluronate, sulfonated chitosan, curcumin, arginine and zinc ions, and infrared proves that sodium hyaluronate, sulfonated chitosan, curcumin, arginine and zinc ions are successfully crosslinked together, so that the novel hyaluronic acid / sulfonated chitosan polysaccharide polymer material is obtained. A series of experiments prove that the high polymer material has multiple effects of isolating bacteria, keeping a wound moist, resisting oxidation, stopping bleeding, promoting healing of the diabetic wound and the like.

This invention discloses a cable production identification and monitoring system and method based on cable images, belonging to the field of image recognition technology. The system includes: acquiring a sequence of cable surface depth images to construct a grayscale surface map along the cable surface depth direction; using the central ridge of the grayscale surface map as a dynamic axis of symmetry, detecting candidate pixels through multi-scale morphological top-hat transformation to form a symmetrical residual distribution map; combining the eight-neighbor gradient direction field and Hessian matrix curvature to remove false defect points, obtaining an effective image, and inputting it into a pre-trained multi-task neural network to simultaneously output a defect segmentation mask and category label; generating a three-dimensional mesh model with dimensional accuracy through Poisson surface reconstruction; and finally, using the physical coordinates of the defect center to drive a laser marking machine to mark a QR code containing key information, which is then associated and stored in a blockchain database. This application improves the accuracy and efficiency of defect identification, realizing the quantitative characterization and full lifecycle management of defects.
