[0037] The following is combined with Figures 1-8 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] In a first aspect, the present invention provides a magnetic shaft with multiple light guiding components, including a base 1, an upper cover 2 and multiple light guiding posts 3; the upper cover 2 is disposed on the base 1, the base 1 is provided with multiple mounting holes 11, the upper cover 2 is provided with a light guiding groove 21, and the light guiding posts 3 pass through the light guiding groove 21 and are disposed in the mounting holes 11.

[0039] In this embodiment, the base 1 is generally flat and rectangular, with two through-holes 11 on its upper surface. The two mounting holes 11 are symmetrically distributed along the longitudinal centerline of the base 1. The upper cover 2 covers the base 1 and is consistent with the outer contour of the base 1. The upper cover 2 has two light guide grooves 21 at positions corresponding to the mounting holes 11. The light guide column 3 is a long, transparent strip that passes through the light guide groove 21 and is then inserted into the mounting hole 11. The column body is located in both the light guide groove 21 and the mounting hole 11. Air channels are provided between the light guide column 3 and the mounting hole 11, and between the light guide column 3 and the mounting groove, to facilitate heat dissipation inside the magnetic shaft.

[0040] After assembly, the base 1, the top cover 2, and the two light guide pillars 3 together form an integrated magnetic shaft.

[0041] Specifically, in this embodiment, the two light guide pillars 3 are symmetrically arranged on the base 1, so that the light source is divided into two paths and diffused upwards evenly, and the brightness difference between the center and the periphery of the keycap is very small; the gap between the light guide pillar 3 and the mounting hole 11 or the light guide groove 21 forms a natural convection path, and the heat can be dissipated upwards along the channel, which significantly reduces the temperature rise of the magnetic shaft surface.

[0042] Meanwhile, the two light guide pillars 3 can also guide light independently, transmitting optical fibers of different colors to form a color mixing or dynamic gradient effect at the top of the shaft, significantly enhancing the visual sense of depth.

[0043] It is understood that in this embodiment, the number of light guide pillars 3 is two, but it is not limited to two. The number of light guide pillars 3 can be increased to three or four, while maintaining central symmetry or ring symmetry.

[0044] In this embodiment, the gap between the light guide post 3 and the light guide groove 21, and the gap between the light guide post 3 and the mounting hole 11 can be appropriately enlarged or reduced according to the heat dissipation requirements, as long as it does not affect the optical uniformity during light guiding.

[0045] In an optional embodiment, the light guide posts 3 are symmetrically arranged on the base 1.

[0046] In this embodiment, the mounting holes 11 of the light guide column 3 are symmetrically arranged, so there is no need to distinguish the front and rear directions of the magnetic shaft during assembly on the production line, and they can be directly aligned, which improves the installation efficiency.

[0047] In this embodiment, after the light guide columns 3 are symmetrically arranged, the light is emitted symmetrically from left to right along the center line, avoiding excessive brightness on one side and eliminating visual fatigue caused by unilateral polarization, resulting in a more balanced visual effect; the superposition of dual light sources enhances the brightness of the central area and improves character recognition.

[0048] In an optional embodiment, the light guide post 3 and the upper cover 2 are fitted with a clearance.

[0049] In this embodiment, a clearance fit is used between the outer wall of the light guide post 3 and the inner wall of the light guide groove 21 of the upper cover 2. There are tiny gaps between the outer surface of the light guide post 3 and the inner surface of the light guide groove 21, and the gaps are continuously distributed along the entire length of the post.

[0050] Specifically, in this embodiment, the gap between the outer wall of the light guide post 3 and the light guide groove 21 of the upper cover 2 allows the light guide post 3 to freely expand and contract when the temperature changes, without squeezing the upper cover 2 or the base 1, thus avoiding stress cracks; at the same time, the gap acts as a microchannel, promoting airflow and improving heat dissipation efficiency.

[0051] In this embodiment, the gap may exist locally at the edge of the light guide post 3, or non-contact support may be achieved by adding protrusions to the inner wall of the light guide groove 21.

[0052] It is understood that in this embodiment, the connection between the light guide post 3 and the upper cover 2 can be a clearance fit, but it is not limited to a clearance fit. It can also be other types of connection, such as snap-fit ​​or bolt connection.

[0053] In an optional embodiment, the connection between the upper cover 2 and the base 1 can be a snap-fit, interference fit, transition fit, bolt connection, or snap-fit.

[0054] In this embodiment, the upper cover 2 has several elastic hooks along its edge, and the base 1 has corresponding slots along its edge. During assembly, the upper cover 2 is pressed vertically against the base 1, and the elastic hooks deform elastically and engage with the slots, forming a detachable and fixed assembly.

[0055] Assembly can be completed without screws or tools, and disassembly can be achieved simply by gently pulling the hooks, greatly improving maintenance efficiency; the hooks and latches are concealed and do not affect the overall appearance.

[0056] It is understandable that the number of hooks and latches can be adjusted according to actual needs to ensure locking force; the hooks can also be placed on the base 1 and the latches on the top cover 2 to achieve the same function.

[0057] In this embodiment, the connection between the upper cover 2 and the base 1 can also be a bolt connection.

[0058] like Figure 6 As shown, the base 1 has a connecting hole 12, which is a threaded hole. The upper cover 2 has a corresponding through hole. After the bolt passes through the through hole, it is threaded into the connecting hole 12, thereby fixing the upper cover 2 to the base 1.

[0059] It is also understood that in this embodiment, the connection between the upper cover 2 and the base 1 is a snap-fit ​​connection, but it is not limited to this method. It can also be an interference fit, a transition fit, etc., as long as it can achieve a fixed connection between the upper cover 2 and the base 1.

[0060] In an optional embodiment, the top end of the light guide post 3 is arc-shaped and has a slope 32 that is adapted to the upper cover 2.

[0061] In this embodiment, the top of the light guide post 3 is designed as an arc-shaped curved surface, and a chamfer is set on the curved surface; the edge of the light guide groove 21 of the upper cover 2 is chamfered with the same angle as the chamfer. The arc-shaped curved surface and the chamfer fit tightly together without any steps.

[0062] Specifically, the top of the light guide post 3 is machined into a continuous, smooth convex arc surface, with the curvature of the surface matching that of the outer surface of the upper cover 2. The highest point of the arc is located on the central axis of the light guide post 3, and the edge smoothly transitions to the side of the post.

[0063] In this setup, the curved surface expands the light-emitting angle, the beveled angle eliminates step shadows, and there are no dark areas on the edges of the keycaps; there is no sharpness when the fingers touch it, improving the comfort of use.

[0064] It is understood that the arc-shaped surface in this embodiment can be changed to a spherical cap or an elliptical arc; the angle of the bevel can be adjusted according to the keycap tilt angle, or it can be changed to a multi-level bevel 32.

[0065] In an optional embodiment, the light guide post 3 is provided with latches 31 at its opposite ends; and the light guide groove 21 is provided with corresponding slots 22 on both sides of its side walls for securing the light guide post 3 within the light guide groove 21.

[0066] In this embodiment, elastic latches 31 are provided on both sides of the middle section of the light guide post 3, and corresponding slots 22 are provided on the side wall of the light guide groove 21 of the upper cover 2. After the light guide post 3 is inserted into place, the elastic latches 31 spring into the slots 22 to form a vertical positioning.

[0067] Specifically, in this embodiment, the latch 31 is wedge-shaped, with its inclined surface 32 facing the bottom of the light guide column 3. Rectangular slots 22 matching the latch 31 are formed on both sides of the light guide groove 21. During assembly, the latch 31 slides into the slot 22 along the inclined surface 32, and the inclined surface 32 self-locks to prevent vertical disengagement. Simultaneously, the latch 31, in conjunction with the slot 22, prevents the light guide column 3 from rotating and swaying laterally, ensuring a constant light output direction. The elastic design of the latch 31 allows for repeated insertion and removal without failure.

[0068] More specifically, in this embodiment, after the upper cover 2 and the base 1 are installed, the light guide post 3 is inserted into the light guide groove 21 and moves downwards, with its bottom end entering the mounting hole 11. When the latch 31 matches the slot 22, the locking and positioning of the light guide post 3 is completed. When the light guide post 3 needs to be removed, the upper cover 2 and the base 1 need to be separated. The light guide post 3 separates from the upper cover 2 and the base 1. As the light guide post 3 continues to be pushed downwards, the latch 31 is compressed by the lower end of the slot 22 and moves out of the slot 22. That is, when the latch 31 moves in the same direction, it first enters the slot 22 and then moves out of the slot 22.

[0069] In this embodiment, the shape of the latch 31 can be varied. For example, the latch 31 can be changed to a dovetail protrusion, and the corresponding slot 22 can be changed to a dovetail slot. Alternatively, the latch 31 can be placed at the upper and lower ends of the light guide post 3 to improve the torsional resistance.

[0070] In an optional embodiment, a baffle 34 is provided on the side of the light guide post 3 away from the upper cover 2; a baffle tongue 13 is provided on the mounting hole 11; when the light guide post 3 is placed in the mounting hole 11, the baffle tongue 13 abuts against the baffle 34.

[0071] In this embodiment, a baffle 34 is horizontally arranged on the outer side wall of the light guide post 3, and a baffle tongue 13 is provided at the opening of the mounting hole 11 of the base 1. When the light guide post 3 is inserted to the bottom, the lower surface of the baffle tongue 13 abuts against the upper surface of the baffle 34 to form an axial limit.

[0072] The cooperation between the baffle 34 and the baffle tongue 13 limits the maximum distance that the light guide post 3 can move downward. The cooperation between the latch 31 and the slot 22 limits the upward movement of the light guide post 3 after it has moved into place. This achieves the limitation of the light guide post 3 in the vertical direction, preventing it from freely detaching from the light guide groove 21 and the mounting hole 11, thus ensuring stability during use.

[0073] In an optional embodiment, a guide groove 14 is provided on the side wall of the mounting hole 11, and a guide strip 33 is provided on the light guide post 3; the guide strip 33 cooperates with the guide groove 14 to limit the movement of the light guide post 3.

[0074] In this embodiment, a guide groove 14 is provided on the side wall of the mounting hole 11, and a guide strip 33 is provided on the outer wall of the light guide post 3. The guide strip 33 and the guide groove 14 slide together along the length of the light guide post 3.

[0075] In this embodiment, the guide groove 14 is a through groove that extends from the side wall of the mounting hole 11 to the outer wall of the base 1.

[0076] In this embodiment, there are two guide grooves 14, which are respectively arranged on both sides of the tongue 13. At the same time, there are two guide strips 33, which are arranged in a one-to-one correspondence with the guide grooves 14.

[0077] In this embodiment, the structure between the two guide grooves 14 is a tongue 13, which can abut against the baffle 34 to achieve the positioning of the light guide post 3.

[0078] In an optional embodiment, the mounting hole 11 is a tapered hole.

[0079] In this embodiment, the mounting hole 11 is set as a tapered hole, with the upper opening being larger than the lower opening, which facilitates the entry of the light guide post 3, improves installation efficiency, and reduces the failure rate.

[0080] Secondly, the present invention provides a keyboard, including a magnetic shaft with multiple light-guiding components as described in any of the foregoing embodiments.

[0081] In this embodiment, the keyboard includes a PCB, keycaps, a return spring, and the aforementioned magnetic shaft. The magnetic shaft is fixed on the PCB, the keycaps are mounted above the magnetic shaft, the return spring is located inside the magnetic shaft, and the magnetic core is placed at the center of the spring.

[0082] This keyboard features multi-point uniform backlighting and efficient heat dissipation, with no dark areas when the keycaps are lit. The magnetic switches can be quickly disassembled and installed, making it easy for users to clean or replace the light guide pillars, thus extending the keyboard's lifespan.

[0083] The beneficial effects of this utility model embodiment are:

[0084] The use of multiple light guide pillars 3 enhances the visual effects; the installation gaps between the multiple light guide pillars 3 create ventilation gaps, forming a through-type heat dissipation channel and improving heat dissipation efficiency.
