The application provides a manufacturing method of a low-altitude aircraft landing gear cover plate, the landing gear cover plate comprising a cover plate body and an edge connecting part, the cover plate body is designed in a curved surface structure, the edge connecting part is distributed in a U shape along the left side, the right side and the bottom of the cover plate body, is smoothly and transitionally connected with the cover plate body and is in a plate structure, the edge is rounded, mounting holes are formed in the edge connecting part, mounting holes are also formed in the top of the cover plate body near the outer edge, carbon fiber SMC prepreg is used as a raw material for preparation during manufacturing of the landing gear cover plate, a mold is designed (the actual size of the mold cavity is 0.5%-1.0% larger than the actual size of the landing gear cover plate) and a process is controlled (precise control is performed on a forming process, temperature fluctuation is less than or equal to ±1℃, pressure fluctuation is less than or equal to ±0.1MPa, curing time error is less than or equal to ±5s, and a shaping tool cooling mode is adopted), so that the prepared landing gear cover plate is stable in size, easy to assemble and capable of guaranteeing the assembly quality of the low-altitude aircraft and flight safety.

The utility model relates to battery safety technical field, the utility model provides a kind of battery and electronic equipment, including shell, pole post being arranged in the end wall of shell, built-in bare cell and current collecting component, lower plastic and high temperature resistance sheet in end wall inside. Among them, high temperature resistance sheet is directly transmitted to the direct transmission of high temperature gas and expansion pressure generated by bare cell when thermal runaway by physical isolation obstruction, significantly reduce the risk of pole post melting or mechanical impact fracture due to thermal shock. High temperature resistance sheet forms reinforced support structure, improves the deformation resistance of shell end, suppresses end wall deformation. This design can maintain the structural integrity and electrical connection stability of pole post and shell in the needle test, reduce the deformation amplitude of shell, and improve the needle test pass rate.

The present application relates to the technical field of photovoltaic module manufacturing, and particularly relates to a solar cell module string carrying device. The solar cell module string carrying device mainly comprises a support, a carrier plate, a heating assembly and a suction cup assembly. The carrier plate is provided as a plurality of carrier plates, the plurality of carrier plates are arranged on the support through fixing members, and a first preset gap is arranged between adjacent two carrier plates. The fixing members can adjust the height position of the carrier plate relative to the support. The heating assembly is provided as a plurality of heating assemblies, and at least one heating assembly is arranged on each carrier plate. The suction cup assembly is partially embedded in the carrier plate, and the suction cup assembly is used for adsorbing the cell sheet so that the cell sheet is attached to the main plane of the carrier plate. The solar cell module string carrying device has a simple structure, the deformation amount of the carrier plate is controllable, the uniformity of the heating of the cell sheet can be improved, the risk of the cell sheet being pulled off from the solder strip is avoided, and the yield of the product is improved.

The present application discloses a novel circlip and a bearing, including an annular body with a notch. First ribs are vertically connected to both axial sides of the annular body. Second ribs are connected to the first ribs and parallel to the annular body, such that the overall cross-section of the circlip is in a "C" shape. When the circlip is installed on the bearing, the inner wall of the first ribs abuts against one side of the groove portion of the inner ring of the bearing, and the outer wall of the second ribs abuts against the other side of the groove portion of the inner ring of the bearing, firmly clamping the two inner rings of the bearing together to ensure the normal operation of the bearing. The first ribs and the second ribs respectively abut against both sides of the groove portion of the inner ring of the bearing, forming a two-way clamping fixing method. The overall cross-section of the circlip is in a "C" shape, and this structure endows the second ribs with a certain elastic deformation ability. During the installation process, the second ribs can adapt to the installation space and force through elastic deformation, achieving uniform and controllable deformation.
