Description

Technical Field

[0001] This utility model relates to the field of mechanical keyboards, and in particular to a magnetic axis key with a locking post structure. Background Technology

[0002] A mechanical keyboard is a type of keyboard. Structurally, each key on a mechanical keyboard has an individual switch to control its closure; this switch is also called a "switch".

[0003] With the development of keyboards, magnetic key switches have also evolved. Among them, toothed key switches have the following advantages: they do not require pins, and the corresponding characters or control signals can be sent through the magnetic induction switch between the key and the PCB board.

[0004] However, existing magnetic axis buttons generally use an interference fit to fit with the PCB board. However, after a period of use, the magnetic axis button will also have a certain displacement, which will affect the stability of the magnetic axis and the magnetic switch.

[0005] Of course, some existing structures use clip-on designs, but they are more troublesome when disassembly is required.

[0006] For example, Chinese patent 202411714079.4 uses a combination of limit pins and pins to ensure stable installation of the button. Utility Model Content

[0007] The main purpose of this invention is to propose a magnetic shaft button with a locking pin structure, which aims to improve the limiting pin structure of the button, making it structurally stable when locked onto the PCB board and more convenient to disassemble when needed.

[0008] To achieve the above objectives, this utility model proposes a magnetic shaft button with a locking post structure, comprising:

[0009] The housing has a sliding cavity, and the bottom wall of the housing has two spaced-apart positioning feet;

[0010] The positioning foot includes two positioning posts spaced apart, a deformation groove between the two positioning posts, and limiting protrusions extending from the ends of the two positioning posts in a direction away from each other.

[0011] The end wall of the limiting protrusion includes a first guide surface and a second guide surface that extend obliquely from the middle to both sides;

[0012] When the positioning pin is inserted into the PCB board, the first guide surface abuts against the bottom wall of the PCB board. When the positioning pin needs to be inserted or removed, the PCB board applies a deformation pressure to the two positioning pins in the direction of the deformation groove, and brings the two limiting protrusions closer together.

[0013] A key shaft is slidably mounted in a sliding cavity, and a magnetic element is provided at the bottom of the key shaft.

[0014] Unlike existing buttons, this design directly mounts the button housing onto the PCB board. The PCB board can be equipped with Hall switches or magnetic coils, which then cooperate with the magnetic components of the key shaft to trigger the button.

[0015] The PCB board is provided with positioning holes that cooperate with the positioning feet. When the limiting protrusion is inserted, the second guide surface contacts the positioning hole and plays a guiding role. When the limiting protrusion is inserted into the lower wall of the PCB board, the first guide surface at the upper end abuts against the lower wall of the PCB board (including the elasticity of the positioning post body), thereby realizing the locking of the housing.

[0016] When unlocking is required, pushing the housing upwards applies inward pressure to the two pillars through the positioning hole, forcing the first guide surface to abut against the positioning hole. This brings the two limiting protrusions closer together, thus unlocking the device.

[0017] Its structure is simple and stable, and compared with existing technologies, its pin installation is more stable and its lower wall structure is simpler. Attached Figure Description

[0036] like Figures 1 to 6 As shown, a magnetic shaft button with a locking post structure includes:

[0037] The housing 1 has a sliding cavity 10 and two spaced positioning feet 2 on its bottom wall.

[0038] The positioning foot 2 includes two positioning posts 20 spaced apart, a deformation groove 21 between the two positioning posts 20, and limiting protrusions 22 extending from the ends of the two positioning posts 20 in a direction away from each other.

[0039] The end wall of the limiting protrusion 22 includes a first guide surface 221 and a second guide surface 222 that extend obliquely from the middle to both sides;

[0040] When the positioning pin 2 is inserted into the PCB board, the first guide surface 221 abuts against the bottom wall of the PCB board. When the positioning pin 2 needs to be inserted or removed, the PCB board applies a deformation pressure to the two positioning pins 20 in the direction of the deformation groove 21 and brings the two limiting protrusions 22 closer together.

[0041] The key shaft 3 is slidably mounted in the sliding cavity 10, and a magnetic element 30 is provided at the bottom of the key shaft 3.

[0042] Unlike existing buttons, this design directly mounts the button housing 1 onto the PCB board. The PCB board can be equipped with a Hall switch or a magnetic coil, which then cooperates with the magnetic component 30 of the key shaft 3 to trigger the button.

[0043] The PCB board is provided with positioning holes that cooperate with positioning feet 2. When the limiting protrusion 22 is inserted, the second guide surface 222 contacts the positioning hole and plays a guiding role. When the limiting protrusion 22 is inserted into the lower wall of the PCB board, the first guide surface 221 located at the upper end abuts against the lower wall of the PCB board (including the elasticity of the positioning post 20 body), thereby realizing the locking of the housing 1.

[0044] When unlocking is required, pushing the housing 1 upwards applies inward pressure to the two pillars through the positioning hole, forcing the first guide surface 221 to abut against the positioning hole. This brings the two limiting protrusions 22 closer together, thus unlocking the device.

[0045] Its structure is simple and stable, and compared with existing technologies, its pin installation is more stable and its lower wall structure is simpler.

[0046] Specifically, the housing 1 is provided with a through hole extending downward from the upper wall, and the through hole is provided with a detachable light guide 5.

[0047] In this embodiment of the invention, the housing 1 is rectangular, and the light guide 5 is the same width as or slightly smaller than the side width of the housing 1.

[0048] The light guide 5 is a flat cuboid, which can give the overall button a better light guiding effect, thereby improving the button's lighting effect.

[0049] Specifically, the upper end of the light guide 5 is provided with an outwardly protruding stop 50, which hooks onto the upper wall of the housing 1. The light guide 5 can be positioned using a simple through hole 4. Furthermore, the setting of the stop 50 effectively ensures that the light from the PCB board can be refracted from bottom to top, thereby improving the light effect of the button.

[0050] In this embodiment of the utility model, the outer side wall of the stop 50 is a first inclined surface, and the other side of the housing 1 is a second inclined surface symmetrical to the first inclined surface. The arrangement of the first and second inclined surfaces can effectively improve the symmetry and aesthetic design of the button.

[0051] Specifically, the positioning post 20 is an elastic post with a semi-circular cross-section, which can achieve a predetermined deformation force.

[0052] In this embodiment of the invention, the housing 1 includes a detachable upper housing and a lower housing.

[0053] The lower shell has spaced support feet on the outer side of its lower wall, and there is a gap between the bottom wall of the lower shell and the PCB board, thereby reducing the impact on the PCB board. Of course, a buffer layer can also be set to reduce the sound of the buttons, further reducing the sound on the basis of the magnetic shaft.

[0054] Specifically, the lower shell is provided with an upwardly extending hollow guide post 6, the guide post having the sliding cavity 10, and the key shaft 3 having a shaft post that mates with the inner wall of the sliding cavity 10, the shaft post being slidably installed within the sliding cavity 10.

[0055] The magnetic component 30 is disposed on the shaft post, thereby ensuring the stable sliding of the key shaft 3.

[0056] In this embodiment of the utility model, a spring 60 is sleeved on the outer peripheral wall of the guide post. The upper end of the spring abuts against the lower wall of the key shaft 3 and applies an upward elastic force to the key shaft 3, thereby realizing the reciprocating movement of the key shaft 3.

[0057] Specifically, the upper shell is provided with a guide hole, and the middle part of the key shaft 3 is provided with a limiting part 7 that abuts against the lower wall of the guide hole, thereby realizing the limiting of the sliding stroke of the key shaft 3, which is simple and stable.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
