Problems solved by technology

However, the components used to provide magnetic attraction are mostly arranged on the lifting mechanism used to provide the keycap action, so that the reaction force caused by the magnetic attraction force needs to be received by the user through the lifting mechanism and then through the keycap, and the force is transmitted. The path passes through many components and has many turning points, coupled with the connection between these components and the force introduced by relative movement, it is easy to make the reaction force felt by the user unstable.

Embodiment Construction

[0035] see Figure 1 to Figure 5 . The key structure 1 according to an embodiment of the present invention includes a base 10 , a keycap 12 , a lifting mechanism 14 , a fixing part 16 , a movable part 18 and a transmission part 20 . The base 10 includes a switch 102 (indicated by a hatched circle on figure 2 Middle) and connection structure 104. The keycap 12 is arranged on the base 10, and the keycap 12 includes a cap body 122 and a connection structure 124 (shown in dotted lines on figure 2 middle), the connection structure 124 is disposed on the bottom surface 1222 of the cap body 122 . The lifting mechanism 14 is connected between the connecting structure 104 of the base 10 and the connecting structure 124 of the keycap 12, so that the keycap 12 can be moved to the unpressed position (such as image 3 The position of the shown keycap 12 relative to the base 10) and the pressing position (such as Figure 5 The shown position of the keycap 12 relative to the base 10 )...

Abstract

The invention discloses a button structure. A magnetic attraction force generated between a fixed part which is arranged fixedly relative to a pedestal and a movable part which is arranged movably relative to the pedestal is used as a driving force for returning a keycap to the original position, and the movable part is positioned between the fixed part and the pedestal. A transmission part between the keycap and the movable part serves as a medium to transmit force from the keycap to the movable part. When the keycap pressing force overcomes the magnetic attraction force, the movable part moves towards the pedestal and triggers a switch. The button structure uses the keycap as the medium to transmit the force from the keycap to the movable part, so that a direct and stable reaction force (or force feedback) is provided for a user, namely, clear pressing hand feeling is provided for the user.

Description

technical field [0001] The present invention relates to a key structure, in particular to a key structure using magnetic attraction force as the driving force for the key cap to return to its original position. Background technique [0002] The traditional button structure uses elastic rubber knobs as the driving force source for the keycap to return to its original position, and this driving force is also the source of the user's touch (or force feedback) when pressing the keycap. When the volume of the button structure is reduced (for example, the height of the button structure is reduced), the space for arranging the elastic rubber knob is also reduced, so that only the elastic rubber knob can provide the driving force of the keycap and the stability of the elastic rubber knob is also limited. also lowered. Too small or unstable driving force will cause the user to feel bad when pressing the keycap. For example, it may be difficult for the user to detect whether the keyc...
