Description

Technical Field

[0001] This utility model relates to the field of magnetic induction keyboard technology, specifically to a magnetic foot support structure for a magnetic induction keyboard. Background Technology

[0002] Magnetic induction keyboards, usually referring to magnetic axis keyboards, are a new type of keyboard based on magnetic induction technology. Each key on a magnetic axis keyboard has a small magnet built into its bottom, and the switch core uses magnetic materials such as rare earth magnets. When the key is not pressed, there is a certain distance between the magnet and the magnetic induction element on the circuit board; when the key is pressed, the distance between the two decreases, and the output parameters of the magnetic induction element change, thereby detecting whether the key is pressed or released.

[0003] Currently, most magnetic keyboards still use traditional snap-on feet, with two recessed grooves carved into the bottom of the keyboard to support the front of the keyboard. However, this design is unsightly in today's world where aesthetics are increasingly important. As for the magnetic feet structure of ordinary keyboards, since magnetic keyboards use several magnetic sensing elements on the PCB to determine whether a key is pressed, directly embedding magnets inside the keyboard's bottom shell would cause magnetic interference to the PCB, preventing the magnetic keyboard from functioning properly. Therefore, this design cannot be directly applied to magnetic keyboards.

[0004] Based on this, this utility model designs a magnetic foot support structure for a magnetic induction keyboard to solve the problem. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic foot support structure for a magnetic induction keyboard, so as to solve the problems of unsightly traditional snap-on foot supports and interference with magnetic induction keyboards in the above-mentioned background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic foot support structure for a magnetic induction keyboard, comprising a bottom shell, a circuit board fixedly mounted on the inner wall of the bottom shell, a set of magnetic induction elements fixedly mounted on the upper surface of the circuit board, a set of magnetic shafts fixedly mounted on the upper surface of the circuit board, a keycap fixedly mounted on the outer surface of each magnetic shaft, a top shell mounted on the outer surface of the bottom shell, a key positioning plate fixedly mounted on the inner top wall of the top shell, each magnetic shaft being adapted to the key positioning plate, two alloy block mounting slots opened on the bottom surface of the bottom shell, a magnetic field shielding alloy block fixedly mounted inside each alloy block mounting slot, a first Hellbeck array magnet fixedly mounted on the inner wall of each magnetic field shielding alloy block, a foot support block provided below the bottom shell, two second Hellbeck array magnets fixedly mounted on the inner bottom wall of the foot support block, the two first Hellbeck array magnets attracting the two second Hellbeck array magnets respectively.

[0007] Preferably, the weak magnetic surface of each first Heilbeck array magnet faces the circuit board.

[0008] Preferably, the strong magnetic surface of each second Hellbeck array magnet faces the circuit board.

[0009] Preferably, the outer surfaces of the two second Helbeck array magnets are jointly fitted with a perforated limiting plate, and the outer surface of the perforated limiting plate is fixedly installed with the inner wall of the foot pad support block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by the cooperation of the first Hellbeck array magnet and the second Hellbeck array magnet, the magnetic field on the side of the first Hellbeck array magnet and the second Hellbeck array magnet that are close to each other can be increased, while the magnetic field on the side that is far away from each other can be greatly reduced, reducing interference to the magnetic induction keyboard. Furthermore, the magnetic field shielding alloy block can further concentrate and absorb the magnetic field above the first Hellbeck array magnet, thereby preventing the first Hellbeck array magnet from interfering with the magnetic axis. It can also be removed at any time while ensuring that the integrity of the bottom of the keyboard shell is not damaged, improving the aesthetics. Moreover, it is suitable for magnetic induction keyboards. Attached Figure Description

[0021] Please see Figure 2 Each of the first Hellbeck array magnets 11 has a weak magnetic surface facing the circuit board 2. The first Hellbeck array magnets 11 can move the strong magnetic surface away from the circuit board 2 and bring the weak magnetic surface closer to the circuit board 2, thereby reducing interference to the circuit board 2.

[0022] Please see Figure 2 Each second Hellbeck array magnet 7 has its strong magnetic surface facing the circuit board 2, which increases the magnetic field on the side near the bottom shell 1, making it easier to attract the first Hellbeck array magnet 11.

[0023] Please see Figure 3The outer surfaces of the two second Hellbeck array magnets 7 are jointly fitted with a perforated limiting plate 8. The outer surface of the perforated limiting plate 8 is fixedly installed with the inner wall of the foot pad support block 10.

[0025] The implementation principle of the magnetic foot support structure of a magnetic induction keyboard according to an embodiment of this application is as follows: First, a first Hellbeck array magnet 11 is installed at the bottom of two magnetic field shielding alloy blocks 9. Then, the two magnetic field shielding alloy blocks 9 are installed in the corresponding alloy block mounting slots 101. At the same time, the side of the first Hellbeck array magnet 11 facing the bottom foot support block 10 is a strong magnet, and the side closer to the circuit board 2 is a weak magnet. The weak magnet is absorbed and concentrated by the magnetic field shielding alloy block 9 covering the first Hellbeck array magnet 11. Then, the circuit board 2 is installed on the bottom shell 1, the magnetic shaft 3 is installed on the key positioning plate 5, and the keycap 4 is installed on the magnetic shaft 3. Next, the top shell 6 is installed around the bottom shell 1 to complete the assembly of the magnetic induction keyboard. Then, the foot support block 10 is brought close to the bottom shell 1, and the installation of the foot support block 10 is completed by the magnetic attraction of the first Hellbeck array magnet 11 and the second Hellbeck array magnet 7 on the foot support block 10, so that the foot support block 10 supports the rear side of the bottom shell 1, making the bottom shell 1 tilt.
