Mechanical logic unit

The invention discloses a mechanical logic unit, and relates to the technical field of mechanical calculation. Comprising a base, two vertical mounting plates are symmetrically arranged on the base, a vertical guide pipe is fixedly arranged between the two vertical mounting plates, and a permanent magnet is movably arranged in the vertical guide pipe; and two iron core electromagnets which are horizontally arranged up and down are respectively arranged between the vertical guide pipe and each vertical mounting plate. The non-contact electromagnetic force between the iron core and the permanent magnet is utilized to generate the bistable characteristic, and failure forms such as fatigue cracks, plastic deformation or fracture damage are avoided; the switching in the bistable form is stable and reversible, can be actively controlled by adjusting the current of the electromagnetic coil, can store mechanical information, represents' 0 'and' 1 'in digital logic, and serves as the most basic unit for constructing a
