Description

Technical Field

[0001] This invention relates to the field of magnetic splicing technology, specifically to a magnetic splicing balancing system with stable movement performance. Background Technology

[0002] Magnetic assembly systems, as a modular assembly technology that combines structural integrity and flexibility, are widely used in fields such as robot research and development, educational toys, and industrial automation. In existing technologies, the splicing stability of magnetic modules largely depends on the inherent magnetic attraction of permanent magnets. The adsorption strength between the magnetic modules and the substrate, as well as the connection strength between modules, are difficult to adaptively adjust according to dynamic scenarios. Under complex working conditions such as tilting and acceleration, problems such as slippage and disintegration are prone to occur.

[0003] Meanwhile, the magnetic force distribution of traditional systems lacks quantitative constraints, and the spatial component distribution of magnetic flux density is unreasonable, resulting in insufficient matching between anti-slip capability and friction coefficient. This makes it difficult to meet the stability requirements of diverse mobile scenarios and cannot balance portability and temporary assembly needs. Summary of the Invention

[0015] The component of the gravity of the magnetic monomer along the direction perpendicular to the magnetic conducting platform is marked as Fg, which is the force that makes the magnetic monomer vertically press the magnetic conducting platform, equal to .

[0016] It should be noted that the core that the magnetic monomer does not slide off the magnetic conducting platform is that the maximum static friction force borne by the magnetic monomer is not less than the component force that makes it have a downward sliding trend:

[0017] The total pressure perpendicular to the surface of the magnetic conducting platform is provided by two parts, one is the attractive force of the magnetic conducting platform to the magnetic monomer, and the other is the component of the gravity of the magnetic monomer along the direction perpendicular to the magnetic conducting platform (the component is the product of the gravity of the magnetic monomer and the cosine value of the 30° magnetic monomer angle of the magnetic monomer);

[0018] The friction coefficient between the contact surface of the monomer and the magnetic conducting platform is multiplied by the total pressure in the above-mentioned perpendicular direction to obtain the size of the maximum static friction force;
