Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-6, the present invention provides embodiments of a magnetically adhesive power generation floor.
As shown in fig. 1 and 2, the magnetic adhesive power generation floor of the present invention includes: a base 20, a first electrode 30 and a second electrode 40 disposed on the base 20, a floor body 11 elastically connected to the base 20, and a magnet 10 disposed on the floor body 11; the magnet 10, the second electrode 40 and the first electrode 30 are sequentially arranged along the elastic direction of the floor body 11, a gap is formed between the first electrode 30 and the second electrode 40, and a magnetic adhesive layer 33 is arranged on one side of the first electrode 30, which is far away from the magnet 10.
It is worth to be noted that the principle of the magnetic adhesive body power generation floor is as follows:
referring to fig. 1 and fig. 6, when the floor body 11 is stepped on, since the floor body 11 is elastically connected to the base 20, that is, the floor body 11 is displaced toward the base 20 (downward, i.e., downward in the drawing), the magnet 10 is also displaced downward, and when the distance between the magnet 10 and the magnetic adhesive layer 33 is short, the magnetic adhesive layer 33 is magnetized, so that an acting force is applied to the first electrode 30, the first electrode 30 is gradually deformed, the gap between the first electrode 30 and the second electrode 40 is gradually reduced, and collision and friction occur, thereby generating electric energy.
When the minimum distance between the magnet 10 and the magnetic adhesive layer 33 is within 1-20mm, the magnetic attraction of the magnet 10 can be ensured to be effective, that is, when the magnet 10 is close to the magnetic adhesive layer 33 to be within 1-20mm, the power generation can be realized. Referring to fig. 1 and 5, when the magnet 10 moves away from the magnetic adhesive layer 33 (upward, i.e., upward in fig. 1) after reaching the minimum distance, the magnetic adhesive layer 33 is demagnetized, the force applied to the first electrode 30 by the magnetic adhesive layer 33 is weakened and disappears, the first electrode 30 is deformed, and the gap between the first electrode 30 and the second electrode 40 is restored. By controlling the magnetization and demagnetization of the magnetic adhesive layer 33, collision and friction between the first electrode 30 and the second electrode 40 can be continuously generated to generate electric energy. The magnet 10 is a permanent magnet 10. The farther the distance between the magnetic adhesive layer 33 and the magnet 10, the smaller the electrical output, and the frequency of movement of the magnet 10 also directly affects the electrical output power.
The magnetic viscous layer 33 and the magnet 10 are matched to generate electricity, so that a micro power generation device is favorably manufactured, magnetic particles in the magnetic viscous layer 33 are usually nanoparticles, even if the micro power generation device is manufactured, the magnetic viscous layer 33 can still normally work, and the output voltage is stable. The magnet 10 is not in contact with the second electrode 40 (or the magnetic adhesive layer 33), and the micro instability caused by human tread errors is greatly reduced by the non-contact pushing mode, so that the voltage output stability is further improved.
In a preferred embodiment of the present invention, the magnetic adhesive layer 33 includes: the nano ferroferric oxide particle nano-scale coating comprises a base layer and nano ferroferric oxide particles dispersed in the base layer. The base layer is a Polydimethylsiloxane (PDMS) layer.

The nano ferroferric oxide particles are dispersed in the substrate layer through the dispersing agent, and when the influence of a magnetic field does not exist, the nano ferroferric oxide particles are in the substrate layer, and a gap exists between the first electrode 30 and the second electrode 40. Due to the influence of the magnetic field of the magnet 10, the nano ferroferric oxide particles are magnetized and move towards the magnet 10 as a whole. Therefore, the magnitude of the force of the magnetic adhesive layer 33 against the first electrode 30 can be controlled by the minimum distance between the magnet 10 and the magnetic adhesive layer 33.
The higher the volume ratio of the nano ferroferric oxide to the substrate layer (namely the PDMS layer), the higher the output voltage, and the volume ratio of the nano ferroferric oxide to the substrate layer is 20-50%.

Specifically, when the floor body 11 is stepped on, the guide post is inserted into the guide groove 21 and compresses the spring 22, and the floor body 11 drives the magnet 10 to move downward to generate electric energy. When the floor body 11 is separated, the spring 22 is deformed again to generate thrust to the guide post, so that the floor body 11 is restored to the original position, and the floor body 11 drives the magnet 10 to be restored to the original position. The magnetic adhesive body power generation floor converts mechanical energy into electric energy in the process of continuously stepping on and recovering the floor body 11.
