The second magnet 14 being set on second part 12.First part 11 is arranged with second part folding, can be specifically that rotation is set
It sets, or sliding setting, for example, the disk seat of washing machine can be first part, upper cover is second part, the two rotation setting.
On the folding direction of first part 11 and second part 12, the first magnet 13 is oppositely arranged with the second magnet 14,
And the opposite one end of the two can generate repulsion.For example, the polarity of the first magnet 13 one end opposite with the second magnet 14 can be with
It is identical, when first part 11 and second part 12 open and close relatively, magnetic can be generated between the first magnet 13 and the second magnet 14
Power, and generated magnetic force is repulsive force.Specifically, first part 11 can be fixed, and second part 12 is opened and closed
Movement, alternatively, second part 12 is fixed, first part 11 carries out open and close movement.Hereafter opened and closed with second part 12
It is described for movement.
At least one of first magnet 13 and the second magnet 14 are electromagnet, and specifically, which may include iron
Core and coil, the coil can be spiral windings, be wrapped in the outside of iron core, which can be connected to electrical connection circuit
In, and then generate magnetic field.Magnetic direction and magnetic field size are adjusted by changing flow direction, the size of electric current so that the first magnet
13 and second the magnetic force of at least one of magnet 14 can be adjusted according to actual demand.That is, the first magnet 13 and second
Repulsive force between magnet 14 can change.For example, repulsive force between the two can be increased so that first part 11 and second
Speed of related movement between part 12 slows down or even second part 12 rests on scheduled open position relative to first part 11
Set place;Alternatively, repulsive force between the two can be reduced, prevent the active force between first part 11 and second part 12 excessive
And it can not close.Specifically, the size of the electric current in above-mentioned electrical connection circuit can be manually changed, and then reaches and adjusts above-mentioned row
The purpose of repulsion.
Under the action of above-mentioned repulsive force, the relatively closed process of first part 11 and second part 12 will be come from

Sliding variable resistance structure 15 in this embodiment can realize the change of resistance by the sliding between self-contained each section,
The resistance in the electrical connection circuit where the resistance i.e. electromagnet, then adjusts between the first magnet 13 and the second magnet 14
The size of repulsive force realizes scheduled folding purpose.
That is, the adjusting of the repulsive force between the first magnet 13 and the second magnet 14 can be by first part 11 and
Relative position between two parts 12 determines.For example, first part 11 moves closer to second part 12, the first magnet at this time
13 and the second repulsive force between magnet 14 gradually increase, cause first part 11 can not be relatively closed with second part 12.But
After above-mentioned sliding variable resistance structure 15 is arranged, when first part 11 is relatively close with second part 12, sliding variable resistance structure 15 makes
It is electrically connected circuit closed, and then increases the resistance in the electrical connection circuit, the electric current for flowing through the first magnet 13 or the second magnet 14 subtracts
Small, repulsive force between the two reduces, and then can reliably close.
