Detailed Description

(example 1)

Referring to fig. 1 to 3, the combined spring and magnet three-degree-of-freedom platform of the present embodiment includes a lower plate 10, an upper plate 20, and three sets of combined spring and magnet assemblies 30 disposed between the lower plate 10 and the upper plate 20.

The three sets of modules 30 are evenly distributed in the plane at 120 degrees to each other (see fig. 2).

Each set of components 30 includes a spring 31, an electromagnet 32, a fixed outer sleeve 33, a lifting inner sleeve 34, and a cross-point 35.

The fixed outer sleeve 33 and the lifting inner sleeve 34 are respectively composed of a bottom plate, a sleeve body and a top plate; the fixed outer sleeve 33 is fixedly connected on the lower bottom plate 10 through a bottom plate, and the top plate of the lifting inner sleeve 34 is connected with the upper platform through a cross joint 35; the diameter of the lifting inner sleeve 34 is smaller than that of the fixed outer sleeve 33; the top plate of the fixed outer sleeve 33 is in an open shape, and the bottom plate of the lifting inner sleeve 34 is positioned in the sleeve body of the fixed outer sleeve 33 and limited below the top plate of the fixed outer sleeve 33; the electromagnet 32 is arranged in the fixed outer sleeve 33, and the bottom plate of the lifting inner sleeve 34 has magnetism.

The spring 31 is disposed outside the fixed outer sleeve 33 and the lifting inner sleeve 34 and is limited between a bottom plate of the fixed outer sleeve 33 and a top plate of the lifting inner sleeve 34, and the spring 31 has three states, namely, an initial state, an operating state (also referred to as a compression state) and a maximum compression state.

In the case where the electromagnet 32 is not energized, there is no external force, and the spring 31 is in the initial state and has the longest length, and the upper stage 20 is supported by the spring 31.

After the electromagnet 32 is powered on, the electromagnet 32 and the upper lifting inner sleeve 34 are mutually adsorbed, the lifting inner sleeve 34 descends along the fixed outer sleeve 33, the spring 31 is compressed to a certain degree, the spring 31 is in a working state (also called a compressed state), and the upper platform 20 descends (wholly or partially).

The electromagnet 32 continues to be energized and the spring 31 is further compressed until it reaches a maximum compression state, at which the upper platform 20 (wholly or partially) is at its minimum.

After the electromagnet 32 is powered off, the lifting inner sleeve 34 is separated from the electromagnet 32, the lifting inner sleeve 34 rises along the fixed outer sleeve 33 under the action of the spring 31, the spring 31 returns to the working state, and the upper platform 20 rises (wholly or partially).

The compression state of the spring 31 can be controlled by turning on and off the electromagnet 32, and the ascending, descending, tilting, and swinging of the upper stage 20 can be controlled.

When the electromagnets 32 of the three sets of assemblies 30 are simultaneously turned on and off, the ascending and descending movement of the upper platform 20 can be realized.

When one or two groups of electromagnets 32 in the three groups of assemblies 30 are powered on and off, the upper platform 20 can be in an inclined state, so that the left-right inclination and the front-back inclination motion are realized.

When the electromagnets 32 of the three sets of assemblies 30 are sequentially turned on and off, the upper platform 20 can be in a swinging state, thereby realizing the left-right swinging and front-back swinging motion.
