Example 1

Referring to fig. 1, 2, 3, 4 and 5, the present embodiment provides a mechanical keyboard shaft, which includes a shaft upper cover 1, a shaft lower cover 2, and a switch cap 3, a spring 4, a stator 5 and a rotor 6, which are installed between the shaft upper cover 1 and the shaft lower cover 2, wherein a top post 31 of the switch cap 3 is disposed through the shaft upper cover 1, a downwardly extending guide shaft 32 is disposed at the bottom of the switch cap 3, the shaft lower cover 2 is provided with a positioning post 21 corresponding to the guide shaft 32, and the top of the positioning post 21 is provided with a guide groove 211 adapted to the guide shaft 32;

a first magnet is mounted on the top of the guide shaft 32, and a second magnet is mounted in the guide groove 211, and the second magnet and the first magnet attract each other.

In this embodiment, the top pillar 31 of the switch cap 3 is disposed through the shaft body upper cover 1, the bottom of the switch cap 3 is disposed with a downwardly extending guide shaft 32, a positioning pillar 21 is disposed in the shaft body lower cover 2 at a position opposite to the guide shaft 32, the positioning pillar 21 is a hollow cylinder, the top of the positioning pillar is open, a guide groove 211 is disposed from top to bottom, and the guide shaft 32 is embedded in the guide groove 211 and can move up and down along the guide groove 211. In addition, one end of the spring 4 is sleeved outside the positioning column 21 and connected with the shaft body lower cover 2, and the other end of the spring 4 is sleeved on the guide shaft 32 and movably connected with the guide shaft; the moving plate 6 and the static plate 5 are both arranged on the shaft body lower cover 2.

The top column 31 of the switch cap 3 can be a cross column, a square column or a cylinder, the structure of the cylinder is the simplest to process requirements, the cross column is the most complex, and the connection between the cross column and the keyboard key cap 100 is the most reliable.

In addition, in order to balance the elasticity of the spring 4, a pair of magnets is arranged between the switch cap 3 and the bottom cover, and the magnets can be neodymium magnets for example, so that the magnets are hard in texture, stable in performance and good in cost performance. The pair of magnets includes a first magnet installed at the top of the guide shaft 32 and a second magnet installed in the guide groove 211. In normal use, they are located on the same vertical line. In this embodiment, the first magnet and the second magnet attract each other. When pressing the button downwards, the power is acted on the fore-set 31 of switch cap 3, and switch cap 3 wholly moves downwards, and spring 4 bounce is stronger more down, but the appeal between the first magnetite and the second magnetite is stronger more closely the guide shaft 32 is apart from the guide groove 211 bottom simultaneously, and this part appeal can balance the resilience force of partly spring 4, and the user can be lighter when pressing the button, alleviates the burden of finger. In addition, it should be noted that, with the switch cap 3 as the force analysis object, the sum of the attraction force (F1) between the first magnet and the second magnet and the gravity (G) applied to the switch cap 3 itself is always smaller than the resilience force (F2) of the spring 4 (i.e., F1+ G < F2) in the process, without considering the friction force. This ensures that the switch cap 3 can be smoothly rebounded without affecting the next depression.

Since the keys of the keyboard are frequently knocked many times, in order to prevent the first magnet from being shaken off or the second magnet from being sucked away, the most secure method is to embed them in the top of the guide shaft 32 and the guide groove 211 respectively. Therefore, a first groove and a second groove may be respectively formed in the top of the guide shaft 32 and the guide groove 211, and a gripper may be provided around the first groove and the second groove for fixing (as shown in fig. 5). In addition, as part of users like to accompany rhythmic sound when pressing keys, the hand feeling can be enhanced, and the mood of the users can be more pleasant when using the keyboard. For example, the length of the first magnet in the vertical direction may be greater than the depth of the first groove, that is, the first magnet protrudes out of the first groove, and one surface of the corresponding second magnet facing the first plane may be a plane (as shown in fig. 3 and 4) or a curved surface, but is not suitable for having an edge, and the first magnet and the second magnet can generate a crisp impact sound when colliding with each other.

Example 2

Referring to fig. 6, in some embodiments of the present invention, a correction post 22 is further disposed on the periphery of the positioning post 21, and an end of the spring 4 is sleeved outside the positioning post 21 and connected to the shaft lower cover 2.
