Description

Technical Field

[0001] This application relates to the field of buttons, and in particular to a button with two LED positions. Background Technology

[0002] As a core component of user interaction, buttons directly impact user experience and production efficiency. Traditional buttons typically employ a single-lamp structure, where a fixed indicator light source is integrated within the button, positioned either at the top or bottom of the screen to match the installation layout of specific devices. This design is widely used in electronic products such as remote controls, control panels, and mechanical keyboards, relying on standardized installation methods to ensure reliable signal transmission and visual feedback. For example, in production lines, manufacturers often need to customize and bulk purchase single-lamp buttons according to the key layout requirements of the final product to meet the needs of different scenarios.

[0003] While single-lamp buttons are functionally mature, this approach has significant shortcomings and limitations. The main problem stems from the fixed button design: because each button is only compatible with one lamp position (e.g., top lamp only or bottom lamp only), manufacturers must produce and manage multiple button types when the terminal device's installation layout changes. This leads to increased production costs, such as the need to maintain two separate molds or inventory systems on different product lines, and also increases supply chain complexity, including wasted storage space, logistical coordination risks, and potential product mismatch issues. For example, during device assembly, if the button layout changes from bottom lamp to top lamp, the entire production line must switch to a different button, which not only delays the production cycle but also easily causes installation errors and quality deviations. A deeper reason lies in the lack of adaptability of existing technology: traditional buttons rely on rigid structural divisions and cannot dynamically switch lamp positions, limiting their applicability in diverse applications. This deficiency ultimately reduces the efficiency of the entire industry, increases resource waste, and complicates user maintenance.

[0004] Therefore, the research and development of new technologies is of great significance and value. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the prior art and provide a dual-lamp button. This button, through dual light guide channels symmetrically arranged within the base, enables a single button to adapt to different installation requirements of the upper or lower lamp position, adapting to multiple installation scenarios to reduce product variety and inventory requirements. It also provides users with more flexible installation options, thereby optimizing equipment deployment and long-term maintenance costs.

[0006] To achieve the above objectives, this application discloses a dual-lamp button, which includes a base body, an operating handle slidably mounted within the base body, a return spring located in the base body and cooperating with the operating handle, and a first lamp position unit and a second lamp position unit symmetrically arranged on both sides inside the base body. The first and second lamp position units have identical structures, each including a light transmission channel and its corresponding light guide output component, thereby achieving the technical objective of a single button device compatible with both upper and lower lamp position button layouts.

[0007] The light transmission channel is a light guide groove structure that extends from the bottom of the base body into its interior, and is used to guide and transmit the light emitted by the external light source along a predetermined path.

[0008] The light-guiding output component is an optical cover integrated on the side of the base body. The optical cover and the output end of the light-guiding groove form a continuous light transmission channel. The optical cover is made of a light-transmitting or semi-light-transmitting material and includes an arc-shaped top surface for upward light transmission, a flat side surface for lateral light transmission, and a connecting slope connecting the arc-shaped top surface and the flat side surface. The connecting slope is configured to conduct a portion of the incident light secondary in the oblique direction, thereby forming a multi-directional composite light emission mode.

[0009] In some embodiments, the optical cover and the base body are integrally formed by injection molding.

[0010] In other embodiments, the optical cover is a separate component that is fixedly mounted to the lateral assembly point of the base body by a mechanical connection mechanism or adhesive bonding.

[0011] Furthermore, the mechanical connection mechanism includes, but is not limited to, a snap-lock structure.

[0012] Furthermore, the snap-locking structure specifically includes a snap-locking boss disposed on the side wall of the base body and a corresponding snap-locking slot disposed on the optical cover body. In the assembled state, the snap-locking boss and the snap-locking slot interlock through elastic deformation, ensuring that the optical path alignment is maintained between the input end of the optical cover and the output end of the light guide groove during this process.

[0013] Compared with the prior art, this application has at least one of the following beneficial technical effects:

[0014] 1. By integrating the dual-lamp positions, the need for separate production is eliminated, allowing a single button structure to adapt to both upper and lower lamp positions, completely avoiding the problems of independent production lines, dual molds, and separate inventory caused by key position differences in traditional solutions.

[0015] 2. Significantly reduces manufacturing and maintenance complexity. Based on the switchable optical path coupling mechanism of the light guide groove and optical cover, only the button direction needs to be adjusted during the assembly stage to match different equipment layouts, effectively reducing production scheduling error rate and spare parts management costs.

[0016] 3. Improve the reliability and scene adaptability of optical indication. Utilize the synergistic light distribution effect of the polyhedral light guide structure to achieve multi-directional uniform light emission in any lamp position activation state, ensuring the operation recognition under different viewing angles.

[0017] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

All terms used in this specification (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. For the sake of brevity and / or clarity, techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail; however, where appropriate, such techniques, methods, and apparatus should be considered part of this specification.

[0025] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the relevant listed items.

[0026] See attached document Figs. 1 to 3 The button device provided in this embodiment generally includes a base body 1, an operating handle 2 that can slide vertically within the base body 1, a reset spring for providing a press-to-reset function, and a first lamp position unit 3 and a second lamp position unit 4 that are symmetrically arranged on both sides inside the base body 1. All of the above components together constitute an integrated button structure and work together to achieve mechanical pressing operation and multi-directional optical indication functions.

[0027] The operating handle 2 is inserted through the top opening of the base body 1 and can slide relative to it in the axial direction. The reset spring is located between the operating handle 2 and the base body 1, with one end abutting against the bottom surface of the base and the other end supporting the operating handle 2, so that it can be automatically reset after being pressed and released.

[0028] In this embodiment, the first lamp position unit 3 and the second lamp position unit 4 are completely identical in structure and function, and are respectively set in the opposite side wall areas of the base body 1, so as to ensure that the button device has consistent optical guidance capability under different installation directions.

[0029] Each lamp unit includes a light transmission channel 5 and a corresponding light guide output component 6. The light transmission channel 5 is a light guide groove structure extending upward from the bottom surface of the base body 1, which is used to guide the light emitted by the externally configured light source along a specific path into the interior of the base body 1. In the normal assembly state, the light source is usually set on the circuit board and located below the base body 1, and the light signal is introduced into the interior of the base body 1 through the light guide groove.

[0030] The light guide output component 6 is mounted on the side of the base body 1 and is optically aligned and connected to the output end of the light guide groove, forming a complete light transmission path through a continuous structure. Specifically, the light guide output component 6 is a structurally complete optical cover, which is made of an optical material with good light transmittance, such as a light-diffusing polymer with high light transmittance or a translucent resin, to meet the requirements of light propagation and scattering in the cover.

[0031] The optical housing employs a multi-faceted structure in its design, including: an upward-facing arc-shaped top surface 601 for upward light propagation; a flat side surface 602 for horizontal light diffusion; and a connecting slope 603 between the two, which is angled to achieve secondary refraction or reflection of incident light, thereby enabling composite light output in an oblique direction. Through the combination of these multi-faceted light-guiding structures, multi-directional composite light distribution modes can be achieved within a limited housing structure, thus improving the user's visibility of light from different viewing angles.

[0032] To facilitate manufacturing and assembly, different connection methods can be used in this embodiment to effectively fix the optical cover and the base body 1. In a preferred embodiment, the optical cover and the base body 1 are integrally formed by a one-time injection molding process. This method can effectively improve assembly accuracy and product consistency, and is suitable for mass production scenarios.

[0033] In another alternative approach, the optical housing is manufactured as a separate component and mounted on the base body 1 via a structural connection. In this connection method, a snap-fit ​​locking structure is preferred for quick and reliable fixing. This structure includes a snap-fit ​​protrusion on the side wall of the base body 1 and a corresponding slot on the inner wall of the optical housing. When the optical housing is inserted, the snap-fit ​​protrusion elastically deforms during installation and interlocks with the slot, thus firmly securing the optical housing in a preset position while maintaining the continuity of the optical path axis between its input end and the output end of the light guide groove, ensuring the stability and consistency of the light guiding performance.

[0034] In practical use, this dual-lamp button, through the symmetrical layout of the first and second lamp units 3 and 4, allows the button's installation orientation to be adjusted according to different device layouts without changing the button structure or redesigning the mold, thus achieving bidirectional compatibility of a unified part in either the upper or lower lamp position. In some typical application scenarios, such as different types of keyboards, due to varying lamp arrangement requirements, traditional solutions require separate upper and lower lamp keys, which not only burdens production line switching and mold conversion but also complicates inventory management. The dual-lamp symmetrical light guide structure used in this embodiment can adapt to these scenarios simply by adjusting the direction, effectively reducing manufacturing costs and the types of spare parts. Furthermore, based on the multi-directional light emission design of the optical housing, the light is evenly distributed, significantly improving the user's operational indicator recognition and enhancing the user experience.

[0035] It should be noted that the detailed structural aspects of the light source driving circuit, signal input control module, and overall housing assembly method are existing technologies or common implementations well-known to those skilled in the art, and therefore are not disclosed in detail in this embodiment. In practical applications, conventional circuit boards, general-purpose LED light sources, and standard button packaging methods can be flexibly selected and used in combination according to product requirements. Those skilled in the art can easily implement the above content without any creative effort.

[0036] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
