Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of magnetic and floats press-key structure, and this magnetic floats press-key structure and is convenient to manufacture, and takes up room little, long service life.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of magnetic floats press-key structure, comprise button, scissor, membrane structure (membrane) and substrate, described membrane structure is covered in substrate uper side surface, substrate uper side surface and button downside surface can the linking together of relative motion by being arranged at scissor therebetween, described button downside surface is installed with the first magnet, membrane structure uper side surface is provided with the second magnet, and the surface that first and second magnet is relative is homopolarity.
As further improvement of the utility model, first and second magnet described is just right along upper and lower to position.
As further improvement of the utility model, described scissor comprises arranged in a crossed manner and the inside casing be articulated and connected and housing, and the upper end of the upper end of inside casing and housing is slidably connected to button downside surface respectively, the lower end of inside casing and the lower end of the housing hollow-out parts be each passed through in membrane structure are slidably connected to substrate uper side surface.
As further improvement of the utility model, described button downside surface side is provided with opening buckle, opposite side is provided with strip chute, the both sides, upper end of inside casing are respectively equipped with a projection, can slide along track length direction in the strip chute that two projections are inserted in button downside surface respectively, the upper end of housing is provided with jointed shaft, this jointed shaft be able to rotate and be arranged in the opening buckle of button downside surface, substrate uper side surface is provided with reverse first, two crotch structures, substrate uper side surface is also provided with positive stop, this positive stop is just relative with the first crotch structural openings direction, the lower end of inside casing and the lower end of housing are respectively equipped with first, two travellers, first traveller be able to slide and be arranged in the first crotch structure, second traveller be able to slide and be arranged in the second crotch structure, and inside casing lower end backstop is in positive stop towards on the sidewall in the first crotch direction.
As further improvement of the utility model, described substrate is aluminium sheet.
The beneficial effects of the utility model are: the utility model utilizes magnet homopolar-repulsion principle to design, repel each other because the second magnet homopolarity on the first magnet on button and substrate produces, magnetic buoyancy is produced, when losing external pressure to button, button is automatically upspring reset under magnetic buoyancy effect, this structure is simple, is convenient to manufacture, and takes up room little, the elasticity of push-button material is not limited, indefatigability, long service life, can meet the demand of ultrathin electronic product button.

Embodiment
Embodiment: a kind of magnetic floats press-key structure, comprise button 1, scissor 2, membrane structure (membrane) 5 and substrate 6, described membrane structure 5 is covered in substrate 6 uper side surface, substrate 6 uper side surface and button 1 downside surface can the linking together of relative motion by being arranged at scissor 2 therebetween, described button 1 downside surface is installed with the first magnet 3, membrane structure 5 uper side surface is provided with the second magnet 4, and the surface that first and second magnet is relative is homopolarity.
The utility model utilizes button 1 effort formation of magnet homopolar-repulsion principle design, (S pole can be all or be all N pole) is repelled each other because first and second magnet homopolarity produces, produce magnetic buoyancy to button 1, when losing external pressure, button 1 is automatically upspring reset under magnetic buoyancy effect, this structure is simple, be convenient to manufacture, take up room little, the elasticity of button 1 material is not limited, indefatigability, long service life.
First and second magnet described is just right along upper and lower to position, ensures that homopolarity is relative all the time, and ensures that button 1 and substrate 6 remain upper and lower relative motion.
Described scissor 2 comprises arranged in a crossed manner and the inside casing be articulated and connected and housing, and the upper end of the upper end of inside casing and housing is slidably connected to button 1 downside surface respectively, the lower end of inside casing and the lower end of the housing hollow-out parts be each passed through in membrane structure 5 are slidably connected to substrate 6 uper side surface.
Described button 1 downside surface side is provided with opening buckle, opposite side is provided with strip chute, the both sides, upper end of inside casing are respectively equipped with a projection, can slide along track length direction in the strip chute that two projections are inserted in button 1 downside surface respectively, the upper end of housing is provided with jointed shaft, this jointed shaft be able to rotate be arranged in button 1 downside surface opening buckle in, substrate 6 uper side surface is provided with reverse first, two crotch structures, substrate 6 uper side surface is also provided with positive stop, this positive stop is just relative with the first crotch structural openings direction, the lower end of inside casing and the lower end of housing are respectively equipped with first, two travellers, first traveller be able to slide and be arranged in the first crotch structure, second traveller be able to slide and be arranged in the second crotch structure, and inside casing lower end backstop is in positive stop towards on the sidewall in the first crotch direction, button 1 and substrate 6 relative motion are, housing upper end and open card buckle-shaped become articulated structure, inside casing upper end edge strip chute reciprocatingly slides, simultaneously, in, the lower end of housing is first, relative sliding in two crotch structures, because inside casing lower end receives the stop of positive stop, it cannot depart from the first crotch structure, same housing lower end also cannot depart from the second crotch structure, this structure is when pressing keys 1, in scissor 2, housing relatively rotates, realize the decline of button 1 and float, can be other structure in addition, as interior, between housing by strip hole coordinate with circular shaft hinged, in, housing upper end and button 1 hinged, lower end and substrate 6 hinged etc., it is all the structure that those skilled in the art are easy to according to the art of this patent expect.
