Abstract: A robot for testing lower limb performance of a spacesuit includes a pressure maintaining box, an air circulation component, an air cooling unit, heat radiating hose components, and two mechanical legs. The air cooling unit is connected with the pressure maintaining box; the air circulation component is arranged in the pressure maintaining box; the mechanical legs are installed on the pressure maintaining box, and the heat radiating hose components are arranged in the mechanical legs; air in the pressure maintaining box is cooled through the air cooling unit and delivered into the heat radiating hose components through the air circulation component; each mechanical leg comprises a thigh, a knee joint component, a shank, an ankle joint component and a foot; the thigh is connected with the shank through the knee joint component; the shank is connected with the foot through the ankle joint component.

Abstract: The present invention relates to the technical field of spacesuit performance tests, and in particular to a robot for testing lower limb performance of a spacesuit, comprising a pressure maintaining box, an air circulation component, an air cooling unit, heat radiating hose components and two mechanical legs.

Abstract: A folding space shelf has a lower backplane and an upper backplane that are connected by one or more hinges, and a pair of top crossbeams and a pair of upper stringers. Each top crossbeam has a first end hinged to an upper portion of the upper backplane and a second end rotatably connected to one of the pair of upper stringers. It further contains a pair of bottom crossbeams and a pair of bottom stringers. Each bottom crossbeam has a first end hinged to a lower portion of the lower backplane and a second end rotatably connected to one of the pair of bottom stringers. The folding space shelf also contains a pair of middle stringers, each having a first end connected to one of the pair of upper stringers and a second end hinged to one of the pair of the bottom stringers.

Abstract: The present invention relates to a space shelf, and particularly to a folding and unfolding space shelf. The lower side of an upper backplane is hinged with the upper side of a lower backplane; one side of a top crossbeam is hinged with the upper side of the upper backplane; the other side of the top crossbeam is rotatably connected with one side of an upper stringer; one side of a bottom crossbeam is hinged with the lower side of the lower backplane; the other side of the bottom crossbeam is rotatably connected with one side of a bottom stringer; both ends of one side of the bottom stringer are hinged with middle stringers; both ends of the lower side of the lower backplane are respectively hinged with a backplane bottom stringer; and a backplane bolt assembly for realizing the relative angle fixation of the upper backplane and the lower backplane is installed on one surface of the upper backplane which faces each crossbeam and stringer.

Abstract: The invention relates to a composite gel polymer Li-ion battery and its producing method. The Li-ion battery cell includes a three-layer composite layer of positive electrode current collector, positive electrode active material and gel polymer electrolyte obtained by a two-layer one-step coating process; a two-layer composite layer of negative electrode current collector and negative electrode active material obtained by a single-layer coating process or a negative electrode two-layer composite layer coated with a little polyurethane adhesive(s) on the surface. The gel polymer Li-ion battery cell is obtained by laminating the resultant two composite layers. The gel polymer Li-ion battery cell has a small thickness and a compact structure, and is laminated closely and easy for preparation and industrial automatic production. The Li battery prepared by the method has a uniform structure, a low internal resistance, a high uniformity, a good unity, and a high safety.

Abstract: The present invention relates to a gel polymer Li-ion battery electrode slice and a method for preparing the same. The electrode slice comprises a two-layer composite structure of electrode active material/gel electrolyte or a three-layer composite structure of electrode active material/gel electrolyte/electrode active material.
