  • Publication number: 20250121242
    Abstract: A trampoline includes an elastic assembly, wherein a portion of the elastic assembly is a bendable energy accumulator; and an elastic support including vertical supporting units and a horizontal supporting unit, two vertical supporting units are arranged at intervals on the horizontal supporting unit, the two vertical supporting units are respectively connected with the first end and the second end to bilaterally support and pre-tension the elastic assembly, and the elastic assembly, when being subjected to a bending deformation, is capable of making at least one of the vertical supporting units and the horizontal supporting unit to be subjected to an elastic bending deformation, so as to apply symmetrical elastic reset force to the first end and the second end, and limit a change of a horizontal distance between the first end and the second end.

  • Publication number: 20250121243
    Abstract: A trampoline includes an elastic plate and a supporting unit, wherein the elastic plate includes a first end and a second end, and a portion, located between the first end and the second end, of the elastic plate is an elastic energy accumulator; the supporting unit includes supporting bodies arranged at the first end and the second end of the elastic plate, and the supporting bodies are capable of supporting the elastic plate and tensioning the first end and the second end of the elastic plate; during bending deformation of the elastic plate, the first end generates a symmetrical turning angle change with respect to the second end; during deformation recovering of the elastic plate, the supporting bodies apply reset force to the first end and the second end by utilizing the potential energy.
