Detailed Description
Referring to fig. 1 to 5, fig. 1 is a schematic diagram of a magnetic-type keyboard 10 according to an embodiment of the present invention, fig. 2 is an exploded view of a magnetic-type key 12 according to an embodiment of the present invention, fig. 3 is an assembled view of the magnetic-type key 12 according to an embodiment of the present invention, and fig. 4 and 5 are schematic diagrams of the magnetic-type key 12 according to an embodiment of the present invention in different operation stages from another view angle. Magnetic type keyboard 10 can have a plurality of magnetic type button 12 according to the design demand, and a plurality of magnetic type button 12 sets up on bottom plate 14, and has spread sheet metal 16 below bottom plate 14 in addition. The sheet metal 16 may be of a large size design, with an area corresponding to the floor 14 and lying directly under the floor 14; alternatively, the metal sheet 16 may be designed to have a small size and an area corresponding to the magnetic-type keys 12, that is, each magnetic-type key 12 has a corresponding metal sheet 16, or several magnetic-type keys 12 are grouped and have a slightly larger corresponding metal sheet 16.
As shown in fig. 2, the magnetic-type keypad 12 mainly includes a bottom plate 14, a thin film circuit board 15, a metal thin plate 16, a key cap 18, a supporting device 20, and a magnetic element 22. The keycap 18 and the metal sheet 16 are disposed on two sides of the bottom plate 14 facing away from each other. The base plate 14 is provided with a first snap structure 24, a second snap structure 26 and a hole 28. The support device 20 includes a first bracket 30 and a second bracket 32. One end of the first support 30 is movably connected to the first fastening structure 24, and the other end is movably connected to the key cap 18, and a magnetic part 34 is further disposed in the middle section of the first support 30. One end of the second support 32 is movably connected to the second latch structure 26, and the other end is movably connected to the key cap 18. The magnetic element 22 is coupled to the base plate 14 through the hole 28, for example, both ends of the magnetic element 22 are engaged with the inner wall surface of the hole 28. The magnetic element 22 is used for attracting the magnetic part 34 on the first bracket 30; therefore, the key cap 18 can move up and down relative to the base plate 14 by the supporting device 20, and a restoring force is provided to the key cap 18 by the magnetic force between the magnetic element 22 and the magnetic attraction portion 34.
The metal sheet 16 is disposed below the base plate 14 and has a bendable cantilever portion 36. The cantilever 36 is aligned to cover or partially cover the hole 28 and can contact or abut against the magnetic element 22. The metal sheet 16 can be made of various materials, for example, the metal sheet 16 can be made of SUS304 (china mark 0Cr18Ni9, which belongs to austenitic stainless steel) material, by which the magnetic element 22 is rigidly supported, and when the magnetic element 22 is to be replaced, the cantilever part 36 is only required to be opened, and as shown in fig. 4, the magnetic element 22 can be taken out from the hole 28 by pulling the cantilever part 36 away from the bottom plate 14; after another magnetic element 22 is mounted in the opening 28 of the base plate 14, the folded cantilever 36 is pressed back by applying force, i.e., the cantilever 36 is substantially in the same plane as the metal sheet 16, as shown in fig. 5, so that the magnetic element 22 can be replaced. In addition, the metal thin plate 16 can be made of SUS430 (china brand is 1Cr17, ferrite stainless steel), which not only provides the above-mentioned reworking property, but also further enhances the magnetic attraction of the magnetic element 22 to the magnetic part 34, effectively improves the pressing hand feeling of the magnetic-attraction type key 12, i.e. the metal thin plate 16 is SUS430, which belongs to a magnetic conductive material, so that the metal thin plate 16 can magnetically attract the magnetic element 22.
In the embodiment of the present invention, as shown in fig. 5, the metal thin plate 16 forms the opening structure 38 at a position corresponding to the magnetic element 22, one end 361 of the cantilever part 36 is connected to an inner wall surface of the opening structure 38, and the other end 362 of the cantilever part 36 is a free end that does not contact the inner wall surface of the opening structure 38; the user can easily open the cantilever 36 via the free end 362 of the cantilever 36 to remove the magnetic element 22. The cantilever portion of the metal sheet 16 may have other embodiments of design. Referring to fig. 6, fig. 6 is a schematic diagram of a magnetic button 12' according to another embodiment of the present invention. In this embodiment, the elements with the same numbers as those in the previous embodiments have the same structures and functions, and the description thereof will not be repeated. The magnetic key 12 ' is different in that the metal thin plate 16 has an opening structure 38 at a position corresponding to the magnetic element 22, one end 361 ' of the cantilever portion 36 ' is connected to an inner wall surface of the opening structure 38, and the other end 362 ' of the cantilever portion 36 ' is connected to the other inner wall surface of the opening structure 38 via the bridge portion 40. The connecting area between the bridge portion 40 and the other end 362 'of the cantilever portion 36' or the inner wall surface of the opening structure 38 is small, so that a user can directly break the connecting portion to open the cantilever portion 36 ', for example, break the connecting portion between the bridge portion 40 and the other end 362' of the cantilever portion 36 'or the connecting portion between the bridge portion 40 and the inner wall surface of the opening structure 38, so that the cantilever wall 36' is pulled away from the bottom plate 14, and the magnetic element 22 is replaced. In the present embodiment, in the opening structure 38, an inner wall surface connected to one end 361 'of the cantilever portion 36' and another inner wall surface connected to the other end 362 'of the cantilever wall 36' are disposed opposite to each other, but not limited thereto. In other embodiments of the present invention, in the opening structure 38, an inner sidewall connected to one end 361 ' of the cantilever portion 36 ' and another inner sidewall connected to the other end of the cantilever portion 36 ' may be adjacent to each other.
In summary, the present invention forms the hole on the bottom plate, the magnetic element is embedded into the hole, and when the metal thin plate covers the bottom plate, the cantilever supports the magnetic element, which helps to prevent the magnetic element from separating from the bottom plate. If the quality of the magnetic element is not good, the user can open the cantilever part through external force, and the cantilever part no longer covers the hole, so that the magnetic element can be taken out from the hole for replacement; after the replacement is finished, the cantilever part can be pressed back to the original position to bear the magnetic element again, the whole metal sheet does not need to be discarded, and the rework cost is greatly saved. Moreover, if the metal sheet is made of magnetic conductivity materials, the metal sheet directly adsorbs the magnetic element, so that the magnetic acting force of the magnetic element can be effectively enhanced, and the stability and the bonding strength of the whole structure can be still obviously improved on the premise of not thickening the magnetic-type keyboard.
