Description

Magnetic keys

The present invention relates to a key, especially a magnetic key with better space utilization.

Existing keys usually use an elastic member (such as a bowl-shaped rubber body) disposed under the key cap and capable of being elastically deformed to provide a feedback force when the key cap is pressed and drive the key cap to reset upward when the key cap is released. However, with the trend toward thinner keyboards, the height of the elastic element must be reduced due to space constraints. However, the reduced height of the elastic element has a shorter service life and the elasticity it can provide is slightly insufficient.

Specifically, please refer to FIGS. 2-7. FIG. 6 is a schematic diagram of the bottom plate 11 according to the first embodiment of the present invention, and FIG. 7 is a schematic diagram of the lifting structure 15 according to the first embodiment of the present invention. As shown in FIGS. 2 to 7, the keycap 14 further includes a first rotating buckling portion 143 and a second rotating buckling portion 144, and the first pivoting structure 1512 is rotatably buckled with the first rotating buckle The portion 143 and the second rotating buckling portion 144 are used to realize the movable connection between the first pivot structure 1512 and the key cap 14. The bottom plate 11 further includes a body 111, a first engagement structure 112, and a second engagement structure 113. The first engagement structure 112 and the second engagement structure 113 protrude from the body 111, and the second engagement structure 113 and the second engagement structure 113 protrude from the body 111. An engaging structure 112 is arranged on opposite sides of the bracket body 1511 and spaced apart. The first engaging structure 112 includes a first vertical portion 1121 and a first horizontal portion 1122 connected to the first vertical portion 1121. The first horizontal portion 1122 and the first vertical portion 1121 are substantially perpendicular to each other, a first engaging portion 1123 is formed between the first horizontal portion 1122 and the first vertical portion 1121; the second engaging structure 113 includes a second vertical portion 1131 and connecting the first One of the two vertical portions 1131 is a second horizontal portion 1132, the second horizontal portion 1132 and the second vertical portion 1131 are substantially perpendicular to each other, and a second engaging portion 1133 is formed between the second horizontal portion 1132 and the second vertical portion 1131. The second pivot structure 1512 rotatably abuts the body 111 of the bottom plate 11 and is movably engaged in the first engaging portion 1123 and the second engaging portion 1133 to realize the movable connection between the second pivot structure 1512 and the bottom plate 11. The first pivoting structure, the first pivoting buckling portion, and the second pivoting structure of the present invention The shapes and numbers of the movable buckling part, the second pivoting structure, the first engaging part, and the second engaging part are not limited to those shown in the drawings of this embodiment, and they depend on actual needs.

Furthermore, the bracket body 1511 includes a first abutment portion 1511D and a second abutment portion 1511E. The first engagement structure 112 further includes a first stop portion 1124 connected to the first vertical portion 1121.

The two abutting portions 1511E restrict the rotation angle of the second pivoting structure 1513 relative to the first engaging portion 1123 and the second engaging portion 1133, thereby restricting the up and down stroke of the keycap 14 relative to the bottom plate 11, thereby lifting operation reliability.

In addition, the bottom plate 11 further includes a first stop structure 114 protruding from the main body 111 and a second stop structure 115 protruding from the main body 111. The second stop structure 115 and the first stop structure 114 are spaced apart from each other. A stop groove 1511F is formed on the body 1511 near the second end. The first stop structure 114 and the second stop structure 115 are located in the stop groove 1511F and used to abut against the wall surface of the stop groove 1511F. The first stop structure 114 and the second stop structure 115 can abut against the wall surface of the stop groove 1511F when the bracket body 1511 moves relative to the bottom plate 11 along a first direction D1 of the parallel keycap long axis 141 to restrict the bracket body The displacement of the 1511 relative to the bottom plate 11 in the first direction D1 prevents the second pivoting structure 1513 from moving in the first direction D1 to be separated from the first engaging portion 1123 and the second engaging portion 1133.

When the keycap 14 is pressed and moves downward relative to the bottom plate 11, the keycap 14 can drive the lifting structure 15 to rotate relative to the bottom plate 11 about the rotation axis R2 of the second pivot structure 1513 along a first rotation direction P1 to The second magnetic member 152 is moved upward to separate from the first magnetic member 13. In the process of pressing the keycap 14 described above, the magnetic attraction between the second magnetic member 152 and the first magnetic member 13 can generate a moment on the lifting structure 15 in a second rotation direction P2 opposite to the first rotation direction P1. Since the keycap 14 is pressed down to generate a moment in the first rotation direction P1, the moment in the second rotation direction P2 generated by the magnetic attraction between the second magnetic member 152 and the first magnetic member 13 will affect the key The cap 14 generates upward resistance to push, so as to enhance the feedback feel when the key cap 14 is pressed. When the keycap 14 is released, the magnetic attraction between the second magnetic member 1513 and the first magnetic member 13 can drive the lifting structure 15 to rotate relative to the base plate 11 about the rotation axis R2 of the second pivot structure 1513 in the second rotation direction P2 Therefore, the keycap 14 is driven to move upward relative to the bottom plate 11 and reset until the first stop portion 1124 and the second stop portion 1134 abut the first abutment portion 1511D and the second abutment portion 1511E, respectively.

It is worth noting that the balance bar long axis 163 is substantially parallel to the keycap long axis 141, and the first pivot structure 1512 is relative to the rotation axis R1 of the keycap 14 and the second pivot structure 1513 is relative to the bottom plate 11 The rotation axis R2 is substantially perpendicular to the balance bar long axis 163 and the keycap long axis 141, that is, the rotation axis R1 and the rotation axis R2 are substantially parallel to the keycap short axis 142. Therefore, when the keycap 14 moves up and down relative to the bottom plate 11, the balance The rod 16 can maintain the stability of the keycap 14 along the direction of the parallel keycap long axis 141 when moving up and down relative to the bottom plate 11, and the lifting structure 15 can keep the keycap 14 short along the parallel keycap when moving up and down relative to the bottom plate 11 Stability of the direction of the axis 142. Thereby, the lifting structure 15 of the present invention can only be supported on a part of the keycap 14 (such as a central part), and it is not necessary to adopt the four supporting keycaps in order to maintain the stability of the keycap movement as in the prior art. The corner mechanism is designed, so the volume of the lifting structure 15 of the present invention can be greatly reduced, and the space between the keycap 14 and the bottom plate 11 can be more effectively used. For example, the space between the keycap 14 and the bottom plate 11 can be used to set the connection or overlap structure of the circuit board 12, so the magnetic key 1 of the present invention has better space utilization.
