Description

Technical Field

[0001] This utility model relates to the field of magnetic axis button technology, specifically to a magnetic axis button switch with a dual light guide structure. Background Technology

[0002] Currently, each key switch (also known as a switch axis or axis) on a keyboard has a pre-reserved structural space for guiding light. In this space, some are designed as slots with no light obstruction from the top or bottom, while others have light-guiding structures installed within the slots to improve light transmission efficiency and optimize the light guiding effect. These light-guiding structures need to avoid the functional parts of the switch body, so they are usually located on the side of the switch axis. However, because the light guide is located on one side of the axis, the illumination range is relatively limited when the keyboard light is guided to the key surface through this structure, typically only illuminating about half of the key. Viewed from the front and back of the keyboard, the overall lighting appears uneven and uncoordinated. Therefore, this invention provides a magnetic axis key switch with a dual light-guiding structure. Summary of the Invention

[0003] This invention provides a magnetic shaft push-button switch with a dual light-guiding structure to solve the problems mentioned in the background art.

[0004] The objective of this utility model is achieved through the following means:

[0005] A magnetic axis push button switch with a dual light guide structure includes a housing and a core structure that is vertically and retractably disposed within the housing. A spring is disposed within the housing to support the core structure. The core structure includes a magnet, and light guides penetrating the housing are disposed on both sides of the core structure.

[0006] Furthermore, both sides of the outer casing are provided with positioning grooves for accommodating the light guide, and the light guide abuts against the outer casing through an outwardly protruding first positioning part.

[0007] Furthermore, the inner wall of the positioning groove is provided with a locking position, and the light guide is engaged with the locking position through an outwardly protruding second positioning part, which is located below the first positioning part.

[0008] Furthermore, the upper end of the light guide is provided with a first emitting inclined surface, and one end of the first emitting inclined surface extends outward to form the first positioning part.

[0009] Furthermore, a second emitting slope is provided at the upper end of the light guide.

[0010] Furthermore, the lower end of the light guide is provided with a lampshade slot.

[0011] Furthermore, the lower end of the light guide is planar.

[0012] Furthermore, a bushing is provided inside the outer casing, and a guide post is provided at the bottom of the shaft core structure for sliding engagement with the bushing. A plurality of inwardly protruding contact portions are provided around the inner wall of the bushing, and a guide groove for limiting the guide post is formed between the plurality of contact portions.

[0013] Furthermore, the magnet is fitted into the bottom of the guide post, and an impact part is provided inside the bushing. When the shaft core structure is lowered to the bottom, the magnet comes into contact with the impact part.

[0014] Furthermore, two guide rails are symmetrically arranged inside the outer shell, and guide blocks for sliding engagement with the guide rails are provided on both sides of the shaft core structure, with protrusions on the top of the guide blocks.

[0015] This invention utilizes light guides installed on both sides of the keys to ensure that the key switches and keycaps are fully covered by light, significantly improving the uniformity and coordination of the lighting, enhancing the keyboard's lighting effect, and improving the user experience. Compared to traditional single-sided light guide structures, the dual-light guide structure significantly increases the illumination range of the keys, making the lighting more uniform and coordinated.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1:

[0026] In this embodiment, refer to Figure 1 - Figure 7 The magnetic axis push button switch with a dual light guide structure is specifically implemented as follows: it includes a housing 1 and a core structure 3 that is vertically and vertically disposed within the housing 1. A spring 2 is disposed within the housing 1 to support the core structure 3. The core structure 3 includes a magnet 4. Light guides 5 that penetrate the housing 1 are disposed on both sides of the core structure 3.

[0027] In this embodiment, both sides of the outer shell 1 are provided with positioning grooves 101 for accommodating the light guide 5. The light guide 5 abuts against the outer shell 1 through the outwardly protruding first positioning part 501, so that the light guide 5 can be stably mounted in the positioning groove 101 by its own weight, and avoids loosening during use.

[0028] Furthermore, the inner wall of the positioning groove 101 is provided with a locking position 102. The light guide 5 abuts against the locking position 102 through an outwardly protruding second positioning part 502, which is located below the first positioning part 501. Through the locking engagement of the second positioning part 502 and the locking position 102, the light guide 5 can be stably fixed within the positioning groove 101. Even if the button switch is flipped or tilted, or in other special circumstances, the light guide 5 will remain in its original position without falling off or shifting. This design not only enhances the structural stability but also improves the product's durability and user experience.

[0029] Furthermore, the upper end of the light guide 5 is provided with a first emitting inclined surface 503. One end of the first emitting inclined surface 503 extends outward to form the first positioning part 501. The design of the first emitting inclined surface 503 at the upper end of the light guide 5 allows light to be emitted more smoothly from the light guide 5, improving the light illumination range and visual effect of the light guide 5. At the same time, the first positioning part 501 formed by the outward extension of the end of the first emitting inclined surface 503 not only facilitates the installation of the light guide 5 with the positioning groove 101, but also enhances the stability of the light guide 5, making the light less susceptible to external interference during transmission, thus ensuring the stability and reliability of the button switch. In addition, the tilt angle of the first emitting inclined surface 503 matches the shape of the housing 1. This design not only makes the button switch more aesthetically pleasing, but also effectively prevents the light guide 5 from being interfered with by external collisions, thus improving the overall service life of the product.

[0030] Furthermore, the lower end of the light guide 5 is provided with a lampshade slot 103. The lower end surface of the light guide 5 and the bottom surface of the outer casing 1 retain a receiving space, thereby forming a lampshade slot 103 with only the lower end open. When the key switch is installed on the circuit board of the external keyboard, the lampshade slot 103 can completely cover the LED beads on the circuit board, thereby preventing light leakage and ensuring that the light emitted by the LED beads can be stably output to the light guide 5, effectively reducing light overflow and leakage.

[0031] Furthermore, the lower end of the light guide 5 is planar, which can effectively disperse the light emitted by the LED beads, making the light more evenly distributed within the light guide 5, thus improving the visual effect and user experience of the button switch.

[0032] In this embodiment, the outer casing 1 includes a top cover 1A and a base 1B. A bushing 104 is disposed within the base 1B. A guide post 301 for sliding engagement with the bushing 104 is disposed at the bottom of the shaft core structure 3. A plurality of inwardly protruding contact portions 1041 are arranged around the inner wall of the bushing 104. Guide grooves are formed between the contact portions 1041 to restrict the guide post 301. This design, using multiple contact portions 1041 to restrict the guide post 301, not only ensures the stability of the guide post 301's vertical movement, preventing the shaft core structure 3 from wobbling or shifting during lifting, but also effectively reduces the friction of the guide post 301's vertical sliding, significantly improving the stability and reliability of the button switch. It also makes the button's tactile feel smoother, enhancing the user experience. The contact portions 1041 are designed with a planar or arc-shaped structure.

[0033] Furthermore, the magnet 4 is fitted into the bottom of the guide post 301, and an impact part 1042 is provided inside the bushing 104. When the button switch is pressed, the shaft core structure 3 quickly descends to the bottom, at which point the magnet 4 impacts the impact part 1042, producing a crisp sound. The impact sound enables the button to confirm its function. The design of the impact part 1042 not only ensures the stability and reliability of the button's confirmation function, but also makes the tactile feedback of the button more distinct through the contact between the magnet 4 and the impact part 1042, improving the user experience. At the same time, the magnet 4 is fitted into the bottom of the guide post 301. This design not only stabilizes the position of the magnet 4, but also assists the guide post 301 in sliding within the bushing 104 through the magnetic force of the magnet 4, further improving the stability and reliability of the button switch.

[0034] Furthermore, two guide rails 105 are symmetrically arranged inside the outer casing 1, and guide blocks 302 are provided on both sides of the shaft core structure 3 for sliding engagement with the guide rails 105. Through the sliding engagement between the guide blocks 302 and the guide rails 105, the shaft core structure 3 can move up and down stably and smoothly within the outer casing 1, further improving the stability and tactile feel of the button switch. This design not only ensures the stability and durability of the button switch during long-term use, but also allows users to experience a smoother and more comfortable user experience when operating the button.

[0035] Furthermore, the top of the guide block 302 is provided with a protrusion 3021 for impacting the upper cover 1A. After the button switch is pressed, the shaft core structure 3 is reset by the force of the spring 2. At that time, the protrusion 3021 on the top of the guide block 302 will impact the upper cover 1A, thereby producing a crisp rebound sound. This design not only provides users with clear button feedback, but also enhances the user's sense of confirmation through sound feedback, further improving user satisfaction. This impact design between the guide block 302 and the upper cover 1A also cleverly utilizes the rebound force of the spring 2, enabling the button switch to automatically provide sound feedback during the reset process. This eliminates the need for additional electronic components or mechanisms, reducing product manufacturing costs while maintaining product stability and reliability.

[0036] This invention utilizes light guides 5 installed through both sides of the keys to ensure that the key switches and keycaps are fully covered by light, significantly improving the uniformity and coordination of the lighting, enhancing the keyboard's lighting effect, and improving the user experience. Compared to traditional single-sided light guide structures, the dual-light guide structure significantly increases the illumination range of the keys, making the lighting more uniform and coordinated.

[0037] Example 2:

[0038] like Figure 8As shown, in this embodiment, as a fallback alternative, the light guide 5 has a second emitting inclined surface 504 at its upper end. The light guide 5 is fixedly engaged with the locking slot 102 only through the second positioning part 502. Compared with the dual fixing method of the light guide 5 in Embodiment 1, this structure simplifies the upper structure of the light guide 5 while maintaining its light-emitting effect, thus ensuring a relatively stable fixed installation effect.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
