  • Patent number: 11446814
    Abstract: An electromagnetic drive spherical robotic wrist with two degrees of freedom and a control method therefor, which is particularly a highly integrated active spherical robotic wrist, realizes pitch and yaw rotation with two degrees of freedom under the direct drive of a coaxial following magnetic torque of a spatial universal rotational magnetic field through a built-in permanent magnet cylinder with radial magnetization of a following mechanism formed by coaxial connection of two output ends of internal and external universal joints with the same rotation center. The electromagnetic drive spherical robotic wrist overcomes the disadvantages of a complex transmission mechanical wrist, and a wrist transmission system has a simple and light structure, high transmission efficiency, good static and dynamic performance, and fast control response.

  • Publication number: 20220234407
    Abstract: Disclosed are a shock absorber and an automobile. The shock absorber includes a shock absorber cylinder and an air spring arranged around the shock absorber cylinder. The air spring includes a damping spring and a piston. A free end of the damping spring is supported at a free end of the piston. A support is disposed between the piston and the shock absorber cylinder. The free end of the piston is supported on the shock absorber cylinder by the support. In the shock absorber according to the invention, the piston and the shock absorber cylinder can be connected in a simple way.

  • Patent number: 9937491
    Abstract: A method for synthesizing (R)-(?)-1-((S)-2-diphosphino ferrocene)-ethyl-diphosphine by: 1) adding vinylferrocene, a chiral catalyst, and toluene to a first drying reactor; adding a phosphorus-hydrogen compound to the first drying reactor and allowing reactants in the first drying reactor to react; cooling the first drying reactor; adding water dropwise to the first drying reactor; extracting, drying, and recrystallizing a product to yield (R)-1-ferrocenylethyl-diphosphine; 2) adding the (R)-1-ferrocenylethyl-diphosphine and ether to a second drying reactor; adding a hexane solution including diethylzinc to the second drying reactor and allowing reactants in the second drying reactor to react; adding a phosphorus-chlorine compound dropwise to the second drying reactor, and heating and refluxing the reaction mixture in the second drying reactor; adding water to quench the reaction mixture in the second drying reactor; and extracting, drying, and recrystallizing the reaction mixture.
