In an embodiment of the present invention, one end of the metal spacer 153 is connected to the pressing handle 130, the metal spacer 153 can be driven to move by the sliding of the pressing handle 130 along the height direction of the casing 120, and the moving direction of the metal spacer 153 is perpendicular to the sliding direction of the pressing handle 130, so that the hall element 151 and the magnet 152 cooperate to generate an induction signal or cut off the induction between the two, thereby realizing the input or cut-off of the signal.

Referring to fig. 3-5, one end of the metal spacer 153 extends between the hall element 151 and the magnet 152 to form a shielding end 1531, the area of the shielding end 1531 is larger than the area of the induction coil of the magnet 152, one end of the metal spacer 153, which is far away from the shielding end 1531, is connected to the handle 130, and when the handle 130 slides vertically along the height direction of the housing 120, the side edge of the handle 130 presses the metal spacer 153 to drive the metal spacer 153 to move laterally, that is, the moving direction of the metal spacer 153 is perpendicular to the sliding direction of the handle 130, when the metal spacer 153 moves laterally until the shielding end 1531 faces the hall element 151 and the magnet 152, the shielding end 1531 completely blocks the induction coil of the magnet 152, and the hall element 151 and the magnet 152 cannot sense to cut off signals; when the metal spacer 153 moves laterally to the shielding end 1531 and is staggered with the hall element 151 and the magnet 152, the shielding end 1531 cannot block the induction coil of the magnet 152, so that a gap is formed between the hall element 151 and the magnet 152 to generate an induction signal, thereby realizing signal input.

More specifically, a boss 131 is disposed at a position of the side of the press handle 130 corresponding to the metal spacer 153, the boss 131 has a first interference surface 1311 and a second interference surface 1312 arranged at an included angle, the second interference surface 1312 is parallel to the sliding direction of the press handle 130, i.e., extends along the vertical direction, the first interference surface 1311 extends obliquely downward from the bottom end of the second interference surface 1312 to the lower end of the press handle 130, so that the included angle between the first interference surface 1311 and the second interference surface 1312 is an obtuse angle (see fig. 4), and when the press handle 130 slides, the first interference surface 1311 and the second interference surface 1312 push against the end of the metal spacer 153 to drive the end to move laterally.

It should be understood that the sensing and shielding of the hall element 151 and the magnet 152 are not limited to the shielding end 1531 disposed at one end of the metal spacer 153, and the hall element 151 and the magnet 152 may be induced by the mutual induction between the hall element 151 and the magnet 152 and the induction between the two may be shielded by the movement of the metal spacer 153.

The driving between the handle 130 and the metal spacer 153 is not limited to the above embodiment, and the handle 130 may drive the metal spacer 153 to move by matching with the metal spacer 153 through another structure. For example, in another embodiment, the metal spacer 153 is an elastic structure, one end of the metal spacer 153 away from the shielding end 1531 is connected to the housing 120, and a substantially middle portion of the metal spacer 153 abuts against a side portion of the pressing handle 130, so that when the pressing handle 130 slides downward, the side portion presses the metal spacer 153 to generate elastic deformation, and further the shielding end 1531 of the metal spacer 153 swings in a tangential direction, so that the shielding end 1531 faces the hall element 151 and the magnet 152 or is staggered with respect to the hall element 151 and the magnet 152.

For another example, in another embodiment, the end of the metal spacer 153 away from the shielding end 1531 is pivoted in the housing 120 and connected to the pressing handle 130, and when the pressing handle 130 slides, the side edge of the metal spacer 153 presses the metal spacer 153, so as to drive the metal spacer 153 to rotate around the pivoting axis, so that the shielding end 1531 of the metal spacer 153 moves along the cutting plane, and the shielding end 1531 faces the hall element 151 and the magnet 152 or is offset from the hall element 151.

Referring to fig. 1-3 again, in the present invention, the housing 120 includes an upper cover 123 and a base 124 that are engaged with each other, the base 124 can be inserted into the upper cover 123 and tightly engaged with the upper cover 123, the engagement between the two is a conventional manner in the art, the sliding cavity 122 is formed between the upper cover 123 and the base 124, a first through hole (not numbered) communicating with the sliding cavity 122 is opened at the top of the upper cover 123, and a certain distance is provided between the bottom wall of the base 124 and the end of the side wall thereof, so that the accommodating cavity 121 can be formed between the bottom wall and the circuit board 110; in addition, a positioning post 1241 protruding toward the middle of the sliding cavity 122 is disposed on the bottom wall of the base 124, and a second through hole (not numbered) corresponding to the first through hole is disposed on the positioning post 1241. After the base 124 is mounted on the circuit board 110, the bottom wall of the base and the circuit board 110 form the accommodating cavity 121, the pressing handle 130 is slidably connected in the sliding cavity 122, the upper end of the pressing handle 130 protrudes out of the upper cover 123 through the first through hole, and the lower end of the pressing handle 130 protrudes out of the base 124 through the second through hole.

As shown in fig. 3, a guiding post 132 is further protruded from a lower end of the pressing handle 130, the pressing handle 130 is slidably installed in the sliding cavity 122 and the guiding post 132 is disposed in the second through hole, the elastic member 140 is sleeved outside the positioning post 1241, two ends of the elastic member respectively abut against the bottom wall of the base 124 and the pressing handle 130, the pressing handle 130 is pressed by the elastic member 140 when sliding downwards under a force, and the pressing handle 130 always tends to slide towards the top of the housing 120 due to the elastic member 140.

In addition, since the upper cover 123 and the base 124 are formed by plastic injection molding, a through hole may not be formed in the bottom wall of the base 124 at a position corresponding to the hall element 151, which does not affect the operation of the hall element 151.

The operation of the magnetic shaft switch 100 of the present invention will be described with reference to fig. 1-5.

As shown in fig. 3-5, when the top end of the pressing handle 130 is pressed, the pressing handle 130 is forced to slide downward, the process compresses the elastic member 140 to deform the elastic member, and during the downward sliding process of the pressing handle 130, the protrusion 131 at the side of the pressing handle 130 presses the metal spacer 153, that is, the metal spacer 153 is pushed by the first collision surface 1311 disposed obliquely to move laterally, when the pressing handle 130 slides to a certain position, the first collision surface 1311 of the pushed metal spacer 153 is transited to the second collision surface 1312, and at this time, the shielding end 1531 on the metal spacer 153 is staggered with the hall element 151 and the magnet 152, that is, the hall element 151 and the magnet 152 are just opposite (see fig. 5), and can mutually sense to generate a sensing signal, thereby forming a signal input of the magnetic axis switch 100.

With continued reference to fig. 3-5, after the pressing handle 130 is released, the pressing handle 130 loses its force, and the elastic member 140 recovers to push the pressing handle 130 to slide upward and reset, in this process, the second collision surface 1312 gradually transits to the first collision surface 1311 to push the metal spacer 153, and the metal spacer 153 moves in the opposite direction to reset due to the inclined arrangement of the first collision surface 1311 until the boss 131 is separated from the collision with the metal spacer 153, and at this time, the shielding end 1531 of the metal spacer 153 faces the hall element 151 and the magnet 152 (see fig. 4), and the sensing between the hall element 151 and the magnet 152 is cut off by the isolation of the shielding end 1531, that is, no sensing signal can be generated between the hall element 151 and the magnet 152, so that the signal of the magnetic axis switch 100 is cut off.

In summary, because the magnetic shaft switch 100 of the present invention has the hall element 151 electrically connected to the circuit board 110, the magnet 152 corresponding to the hall element 151 is disposed in the casing 120, and the movable metal spacer 153 is disposed between the hall element 151 and the magnet 152, so that the metal spacer 153 is driven to move by the sliding of the handle 130 to change the signal change between the hall element 151 and the magnet 152 to realize the instant input or cut-off function of the switch, thereby avoiding the problem of asynchronous and unstable input caused by the way that the magnet approaches or separates from the hall element to change the distance in the prior art to realize the signal receiving and cut-off, ensuring the stable signal input of the magnetic shaft switch 100, further stabilizing the performance of the mechanical keyboard, and prolonging the service life thereof.

Correspondingly, the mechanical keyboard with the magnetic axis switch 100 has the same technical effect.

The structure of other parts of the mechanical keyboard related to the present invention is well known to those skilled in the art, and will not be described in detail herein.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
