Abstract
The invention belongs to the field of magnetic suspension, and particularly relates to a magnetic suspension swivel chair which comprises a chair body, a bottom plate and a plurality of permanent magnet units arranged between the chair body and the bottom plate; the permanent magnet unit comprises a plurality of permanent magnets, spacing bars and magnetic conduction plates, wherein the permanent magnets are arranged below the seat body and above the bottom plate at intervals, the spacing bars are used for spacing the permanent magnets, and the magnetic conduction plates are arranged at the side ends of the permanent magnets at the outermost ends. The magnetic suspension swivel chair saves energy. The permanent magnet adopts a magnetic array to have large suspension force on the structure, can meet the requirement of tension and pressure and has stable system. The spacing bars and the magnetic conduction plates reduce magnetic leakage.
Description
Technical Field
The invention belongs to the field of magnetic suspension, and particularly relates to a magnetic suspension swivel chair.
Background
The current leisure swivel chair has various varieties, and along with the development of science and technology, the increasingly popular furniture needs more and more new technologies to be integrated, so that more and more new experiences and feelings are brought to a user while the daily life is convenient.
On the other hand, magnetic suspension technology is becoming mature, and magnetic suspension sound boxes, magnetic suspension tellurion and the like begin to enter the daily life of people. However, the magnetic field in the magnetic suspension product is divergent, and the bearing capacity is small. And the magnetic force change required by people to sit on the front swivel chair and the back swivel chair is huge, so the magnetic suspension technology is not applied to the swivel chairs all the time.
Disclosure of Invention
The invention aims to provide a magnetic suspension swivel chair.
In order to achieve the purpose, the invention adopts the following technical scheme:
a magnetic suspension swivel chair comprises a chair body, a bottom plate and a plurality of permanent magnet units arranged between the chair body and the bottom plate; the permanent magnet unit comprises a plurality of permanent magnets, spacing bars and magnetic conduction plates, wherein the permanent magnets are arranged below the seat body and above the bottom plate at intervals, the spacing bars are used for spacing the permanent magnets, and the magnetic conduction plates are arranged at the side ends of the permanent magnets at the outermost ends.
The bottom plate is provided with a circuit board, an electromagnetic coil, a laser emitter and a cooling unit, wherein the electromagnetic coil, the laser emitter and the cooling unit are connected with the circuit board; the electromagnetic coils are uniformly arranged on the periphery of the bottom plate.
The seat body is provided with a photovoltaic panel and a rechargeable battery electrically connected with the photovoltaic panel; the rechargeable battery is connected with the circuit board.
The seat body is provided with a pressure sensor and a position sensor which are connected with the controller.
Compared with the prior art, the invention has the beneficial effects that:
(1) the energy is saved. The permanent magnet adopts a magnetic array to have large suspension force on the structure, can meet the requirement of tension and pressure and has stable system. The spacing bars and the magnetic conduction plates reduce magnetic leakage.
(2) Is stable and safe. The multi-dimensional direction automatic adjustment has good automatic adjustment effect and strong stability. The permanent magnet is used as a main part, and the electromagnetic coil is used as a supplement, so that the safety is higher.
(3) The charging is contactless laser charging, and the use is not required to be interrupted during charging.
(4) Simple use, strong interest and more comfortable than the conventional swivel chair. The science and technology sense is strong.
