Abstract: Provided is a treadmill, which includes a running belt, a running deck, a base frame assembly, and a cushioning means arranged between the running deck and the base frame of the base frame assembly. The running deck of the treadmill is only supported at its two ends, and the force exerted by the exerciser on the running belt and the running deck is reduced through the cushioning means, thereby providing effective training results.

Abstract: The disclosure relates to an exercise device, which includes a frame assembly, a running deck inclined at a predetermined angle relative to a base frame, a running belt, and a main cover. The inclined running deck, together with the main cover, provides space for accommodating the motor, which advantageously extends the area for the running belt. The present disclosure also provides an exercise system that includes the exercise device described above and a desk. The exercise system of the present disclosure allows users to engage in activities such as work while exercising.

Abstract: The present invention relates to the technical field of lithium metal batteries, and relates to a lithium metal battery electrolyte containing an aromatic compound as a diluent. The electrolyte contains a lithium salt, a solvent for dissolving the lithium salt, and a diluent; the diluent is an aromatic compound, and the diluent is used for inhibiting lithium dendrites generated due to uneven deposition of a lithium metal anode in the lithium metal battery during a cycle process, and is used for inhibiting the lithium metal anode in the lithium metal battery from reacting with the electrolyte.

Abstract: A biomimetic tower climbing robot and a tower climbing method thereof are provided. The robot mainly includes a main control body module and clamping and moving mechanism modules; two ends of the main control body module are connected to one clamping and moving mechanism module through an elastic universal joint respectively, two clamping and moving mechanism modules can alternately lock and unlock an anti-fall track of an iron tower, and the main control body module alternately pushes the clamping and moving mechanism module at its upper end upwards and pulls the clamping and moving mechanism module at its lower end upwards to achieve climbing of the robot along the anti-fall track.

Abstract: Disclosed in the present invention are a heavy rare earth alloy, neodymium-iron-boron permanent magnet material, a raw material, and a preparation method. The heavy rare earth alloy comprises the following components: RH: 30-100 mas %, not including 100 mas %; X, 0-20 mas %, not including 0; B: 0-1.1 mas %; and Fe and/or Co: 15-69 mas %, RH comprising one or more heavy rare earth elements in Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Sc, and X being Ti and/or Zr. When the heavy rare earth alloy of the present invention is used as a sub-alloy to prepare the neodymium-iron-boron permanent magnet material, a high utilization rate of heavy rare earth is achieved, so that the coercivity can also be greatly improved while the neodymium-iron-boron permanent magnet material maintains high remanence.
