This utility model relates to the field of new energy vehicle battery testing technology, and discloses a new energy vehicle battery testing device, including an operating platform, two conveyor belts, a rotating rod, and a pressure plate. The two conveyor belts are respectively located at both ends of the top of the operating platform. A support platform is fixedly connected to the top of the operating platform, and an L-shaped plate is also fixedly connected to the top of the operating platform. The rotating rod is rotatably connected inside the L-shaped plate, and a continuous conveyor plate that cooperates with the support platform is fixedly connected to its bottom. Both sides of the continuous conveyor plate have conveyor grooves, each of which cooperates with a corresponding conveyor belt. The beneficial effects of this utility model are that it ensures continuous and complete test data, significantly improves the accuracy and reliability of test results, and the continuous testing process can comprehensively evaluate the battery's performance and health status, reduce test errors, and promptly identify and eliminate potential safety hazards in the battery. This is of great significance for improving test quality, ensuring battery safety, and promoting the progress of the new energy vehicle industry.

This invention provides a tin selenide-based nanozyme, comprising tin selenide, with tannic acid and tetravalent cerium ions conjugated on the surface of the tin selenide. The invention also provides a method for preparing the above-mentioned nanozyme, comprising mixing tin selenide with anhydrous ethanol and ultrasonically dispersing the mixture; centrifuging the resulting mixture to obtain a supernatant, further centrifuging the supernatant to obtain a tin selenide nanosheet solution; adding the above tin selenide nanosheet solution and tannic acid solution together to deionized water; subsequently adding cerium nitrate solution and continuing stirring; then adding sodium hydroxide solution to adjust the pH to 8.0; after the reaction is complete, the tin selenide-based nanozyme is obtained. This invention also provides the application of the above-mentioned tin selenide-based nanozyme in the preparation of anti-atherosclerotic drugs. The nanozyme of this invention can effectively alleviate the progression of atherosclerosis.

This utility model relates to the technical field of electric bed frame devices, specifically an electric bed frame with a rotating bed surface function, comprising: a bed surface assembly; a bed surface frame assembly, on which a turntable assembly and a drive assembly are provided, the drive assembly causing the turntable assembly to rotate; and a backrest and leg-raising assembly, on which the turntable assembly is provided, allowing the bed surface assembly to be in either a backrest or leg-raising position. The bed surface assembly includes a backrest board, a lumbar support board, a hiprest board, a thigh board, an upper leg board, and a lower leg board, which are sequentially distributed from one side to the other and are hinged to each other sequentially from one side to the other. This device allows an elderly person in a sitting position to rotate to the side of the bed, thus facilitating their getting out of bed.

The present application relates to the field of logistics equipment, in particular to a high-speed material box stacking machine, comprising a sliding seat, a vertical rod fixedly installed on the sliding seat, a placing rack slidingly installed on the vertical rod, a driving mechanism for driving the placing rack to move along the vertical rod, and a discharging mechanism arranged on the placing rack. The high-speed material box stacking machine is provided with a correcting mechanism. On the one hand, the posture of the material box is adjusted to ensure that the side of the material box with a label is close to the scanning mechanism, thereby improving the scanning accuracy. On the other hand, the push plate is driven to be close to the material box to clean the side wall of the material box, thereby avoiding the influence of dust on the side wall of the material box on the recognition effect of the label. Furthermore, the dust generated by the cleaning roller can be adsorbed when the push plate moves.
