Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a light-guiding key switch and a keyboard. Background Technology

[0002] As a crucial human-computer interaction device, the keyboard's user experience is increasingly valued by both users and manufacturers. Backlighting, in particular, not only provides visibility in low-light environments but also serves as an important means of personalization and enhancing the device's aesthetics. Market research revealed that existing keyboards typically use a separate light source under each key, guided by a single light guide for each key switch to achieve backlighting and aesthetic effects. However, reviewing user feedback showed that existing key switches, with their single light guide, offer limited lighting performance and suffer from inconsistent light distribution and limited light output.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 4 This utility model provides a light-guiding push button switch, which includes a housing 100. The housing 100 is provided with two light guides 200, which are respectively disposed on opposite sides of the housing 100. The light guides 200 can guide the illumination light received from the bottom of the housing 100 to the top of the housing 100.

[0024] It is understood that the light guide 200 is made of a light-transmitting material, such as light-transmitting plastic. When the light guide button switch of this embodiment is installed on the keyboard, the two light guides 200 of the light guide button switch can be arranged one-to-one on the upper side of the two keyboard light sources to achieve effects such as dual-color light emission and dual-color mixing.

[0025] Through the above structure, the light-guided push-button switch of this solution, by setting two light guides 200 in the housing 100, can receive illumination light more comprehensively from the bottom of the housing 100, so that the light leading to the top covers a wider range, effectively reducing or avoiding the problems of local light spots and insufficient light intensity that occur with a single light guide 200, and significantly improving the uniformity of light distribution at the top of the light-guided push-button switch; on the other hand, the two light guides 200 can guide light independently or in combination, providing structural support for realizing diverse lighting effects (such as gradient light effects, multi-color superimposed light effects, etc.), breaking through the limitation that a single light guide 200 can only achieve a single light effect, and greatly improving the lighting performance of the light-guided push-button switch.

[0026] In some embodiments, four light guides 200 are provided, and the four light guides 200 are respectively provided on the four sides of the housing 100.

[0027] The light guide 200 is disposed on the housing 100. For details, please refer to [reference needed]. Figures 2 to 4 The housing 100 has two through mounting holes S, and two light guides 200 are respectively inserted through the two mounting holes S. The housing 100 includes an upper cover 110 and a base 120 connected vertically. The upper cover 110 and the base 120 are respectively provided with a first through hole 111 and a second through hole 121, which are connected to form the aforementioned mounting holes S.

[0028] Through the above structure, the two independent mounting holes S ensure that the two light guides 200 are independent of each other and do not interfere with each other. That is, each light guide 200 can independently transmit light from different or the same light sources.

[0029] In some embodiments, the light guide 200 is disposed on the housing 100. Specifically, the housing 100 and the light guide 200 are integrally formed (the integrally formed structure includes a partially integrally formed structure). The light guide 200 in the partially integrally formed structure can be configured in the following ways: the upper cover 110 and the light guide 200 can be integrally formed through a secondary injection molding process, with the light guide 200 passing through the second through hole 121 of the base 120; or, the base 120 and the light guide 200 can be integrally formed through a secondary injection molding process, with the light guide 200 passing through the first through hole 111 of the upper cover 110.

[0030] In this embodiment, refer to Figures 1 to 3 The upper cover 110 has an opening 112 on its side that communicates with the corresponding first through hole 111.

[0031] With the above structure, the opening 112 on the side of the top cover 110 provides an additional lateral outlet for light, which can increase the illumination angle and achieve a unique lighting effect.

[0032] In this embodiment, both the upper cover 110 and the base 120 abut against the light guide 200 to restrict the vertical movement of the light guide 200 passing through the mounting hole S. Specifically, refer to... Figures 2 to 4 The light guide 200 is provided with a first abutting block 210 and a second abutting block 220. The first abutting block 210 abuts against the upper side of the base 120, and the second abutting block 220 abuts against the lower side of the upper cover 110.

[0033] In some embodiments, the upper cover 110 and the base 120 both abut against the light guide 200 to restrict the up-and-down movement of the light guide 200 passing through the mounting hole S. Specifically, the light guide 200 is provided with a third abutting block, which is sandwiched between the upper cover 110 and the base 120.

[0034] This invention also proposes a keyboard that includes the aforementioned light-guiding key switch. This structure enables the achievement of more diverse lighting effects.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
