Description

Technical Field

[0001] This utility model relates to the field of keyboard accessories technology, specifically to a light guide column. Background Technology

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. Keyboards typically have many keys, and to meet the diverse needs of users, keyboards have evolved to include models with backlit keys. Keyboard illumination is achieved by placing a light source under each keycap, and then diffusing the light through a light guide column within the keycap to achieve the effect of the entire key illuminating. For stable installation, the head of the light guide column is usually made relatively large, while the bottom insert is made smaller. A positioning block is set on the outer wall of the insert. After installation, the head will cooperate with the positioning block to clamp in the corresponding position. However, with this setup, the space where the size of the light guide column head is larger than the insert will be blocked by the installation position, resulting in low utilization and insufficient light guiding effect. Utility Model Content

[0003] In summary, to overcome the shortcomings of the existing technology, this utility model provides a light guide column with better light guiding effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a light guide column, comprising a light guide head and a connecting block, wherein the connecting block is located at the bottom of the light guide head, the top of the light guide head is provided with an inclined first light guide surface, the bottom surface of the light guide head is larger than the connecting block, the side wall of the connecting block is provided with a positioning block that is spaced apart from the light guide head, the first light guide surface is provided with a plurality of light-scattering protrusions, and the bottom of the connecting block is provided with a light-amplifying arc groove, the center of the light-amplifying arc groove being located below the bottom surface of the connecting block.

[0005] With this setup, the light guide column is made entirely of transparent material. In use, this light guide column is installed on the keyboard keycaps. The positioning block, along with the larger light guide head, clamps the light at the corresponding position on the keycap. When the keyboard light source emits light, the light first illuminates the connecting block, and then the connecting block transmits the light to the light guide head. Because the bottom of the connecting block has a light-expanding arc groove, the light will begin to spread out to both sides when it illuminates the arc groove. This allows the light source to spread out to both sides when it reaches the light guide head, making better use of the space on both sides and improving the light guiding effect. The curvature of the light-expanding arc groove can be calculated to ensure that it directly illuminates the light guide head for diffusion and reflects off the side wall of the connecting block, achieving the best effect.

[0006] Furthermore, a gap is provided between the bottom two sides of the light-expanding arc groove and the two side walls of the connecting plug.

[0007] With this setup, the two sides at the bottom do not need to change direction; direct sunlight achieves the best conduction effect. Therefore, it is sufficient to set an arc diffuser in the middle.

[0008] Furthermore, the astigmatism bump is a triangular pyramid shape, with the bottom edge of the top surface of the astigmatism bump set horizontally, and the other two sides facing to the sides.

[0009] With this setup, the triangular pyramid ensures that light scatters in the directions of its three faces, with one face facing upwards and the other two facing to the sides, minimizing useless direct downward illumination and resulting in better light.

[0010] Furthermore, a gap is provided between two adjacent astigmatic bumps.

[0011] This configuration preserves the light-guiding effect of the first light-guiding surface while the light is diffused by the light-scattering bumps, resulting in better light guiding performance.

[0012] Furthermore, the connecting plug is provided with a positioning strip that is parallel to and gapped with the light guide head. The positioning strip is located on the side wall of the connecting plug facing away from the first light guide surface, and a second light guide surface is provided at the bottom of the positioning strip.

[0013] With this setup, the positioning strip can achieve the same positioning effect as the positioning block. At the same time, when the bottom light source shines on the second light guide surface at the bottom of the positioning strip, it will be changed by the light guide, so that it shines towards the space blocked at the bottom of the first light guide surface, making full use of the space of the light guide head and achieving a better light guiding effect.

[0014] Furthermore, the positioning strip has a vertically arranged transition surface located above the second light guide surface.

[0015] With this setup, since the top of the positioning strip is also obstructed, setting a slope at the top is useless and would only increase the height of the positioning strip, making installation more difficult. Therefore, a transition surface is set at the top to increase the distance between the second light guide surface and the obstructing surface, thus improving the light guiding effect.

[0016] Furthermore, the positioning block is located on the side wall of the connecting plug facing the first light guide surface, and there are two positioning blocks, which are respectively disposed on both sides of the connecting plug.

[0017] With this setup, the positioning block will be placed on the opposite side of the positioning strip, thus achieving a better stabilizing effect. However, the bottom surface of the positioning block at this position can only illuminate the back of the light guide head, resulting in poor performance. Therefore, the positioning block does not need to be set in a strip shape; it is sufficient to set two small blocks on the two sides respectively.

[0018] Furthermore, the light guide head has a third light guide surface that is inclined on the side facing away from the first light guide surface. The bottom edge of the third light guide surface coincides with the connecting plug, and a fixing block is provided on each side of the bottom of the third light guide surface.

[0019] With this setup, the light shining towards the back side inside the light guide head will be redirected by the third light guide surface due to reflection and refraction from various surfaces, causing it to shine upwards as much as possible, resulting in better light guiding effect. Meanwhile, the fixing block at the bottom ensures stability. Attached Figure Description

[0024] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0025] Referring to the accompanying drawings, this utility model provides the following technical solution: a light guide column, including a light guide head 1 and a connecting plug 2, wherein the connecting plug 2 is located at the bottom of the light guide head 1, the top of the light guide head 1 is provided with an inclined first light guide surface 101, the bottom surface of the light guide head 1 is larger than the connecting plug 2, the side wall of the connecting plug 2 is provided with a positioning block 201 that is spaced apart from the light guide head 1, the first light guide surface 101 is provided with a plurality of light-diffusing protrusions 1011, and the bottom of the connecting plug 2 is provided with a light-amplifying arc groove 202, the center of which is located below the bottom surface of the connecting plug 2.

[0026] With this setup, the light guide column is made entirely of transparent material. In use, this light guide column is installed on the keycaps of the keyboard. The positioning block 201 will cooperate with the larger light guide head 1 to clamp it at the corresponding position on the keycap. When the light source on the keyboard emits light, the light source will first illuminate the connecting plug 2, and then be conducted by the connecting plug 2 to the light guide head 1. Since the bottom of the connecting plug 2 is provided with a light-expanding arc groove 202, the light will start to spread out to both sides when it illuminates the light-expanding arc groove 202. This allows the light source to spread out to both sides when it reaches the light guide head 1, making use of the space on both sides and improving the light guiding effect. The curvature of the light-expanding arc groove 202 can be calculated to ensure that it can directly illuminate the light guide head 1 for diffusion and illuminate the side wall of the connecting plug 2 for reflection to achieve the best effect.

[0027] In this preferred embodiment, a gap is provided between the bottom two sides of the light-expanding arc groove 202 and the two side walls of the connecting plug 2.

[0028] With this setup, the two sides at the bottom do not need to change direction; direct sunlight achieves the best conduction effect. Therefore, it is sufficient to set an arc diffuser in the middle.

[0029] In this preferred embodiment, the diffuser bump 1011 is a triangular pyramid shape, with the bottom edge of the top surface of the diffuser bump 1011 being horizontally arranged, and the other two sides being arranged facing to the sides.

[0030] With this setup, the triangular pyramid ensures that light scatters in the directions of its three faces, with one face facing upwards and the other two facing to the sides, minimizing useless direct downward illumination and resulting in better light.

[0031] In this preferred embodiment, a gap is provided between two adjacent astigmatism bumps 1011.

[0032] With this configuration, the light guiding effect of the first light guiding surface 101 is preserved while the light is emitted by the diffuser bump 1011, resulting in a better light guiding effect.

[0033] In a preferred embodiment, the connecting plug 2 is provided with a positioning strip 203 that is gapped and parallel to the light guide head 1. The positioning strip 203 is located on the side wall of the connecting plug 2 facing away from the first light guide surface 101, and a second light guide surface 2031 is provided at the bottom of the positioning strip 203.

[0034] With this configuration, the positioning strip 203 can achieve the same positioning effect as the positioning block 201. At the same time, when the bottom light source shines on the second light guide surface 2031 at the bottom of the positioning strip 203, it will be changed by the light guide surface 2031, so that it will shine towards the space blocked at the bottom of the first light guide surface 101, making full use of the space of the light guide head 1 and improving the light guiding effect.

[0035] In a preferred embodiment, the positioning strip 203 is provided with a vertically arranged transition surface 2032 located above the second light guide surface 2031.

[0036] With this setup, since the top of the positioning strip 203 is also obstructed, setting a slope at the top is useless and would only increase the height of the positioning strip 203, making installation more difficult. Therefore, a transition surface 2032 is set at the top to increase the distance between the second light guide surface 2031 and the obstructing surface, thus improving the light guiding effect.

[0037] In this preferred embodiment, the positioning block 201 is located on the side wall of the connecting plug 2 facing the first light guide surface 101. There are two positioning blocks 201, and the two positioning blocks 201 are respectively disposed on both sides of the connecting plug 2.

[0038] With this setup, the positioning block 201 will be placed on the opposite side of the positioning strip 203, thereby achieving a better stabilizing effect. However, at this position, the bottom surface of the positioning block 201 can only illuminate the back of the light guide head 1, which is not effective. Therefore, the positioning block 201 does not need to be set in a strip shape; it is sufficient to set two small blocks on the two sides respectively.

[0039] In a preferred embodiment, the light guide head 1 has a third light guide surface 102 that is inclined on the side facing away from the first light guide surface 101. The bottom edge of the third light guide surface 102 coincides with the connecting plug 2, and a fixing block 1021 is provided on each side of the bottom of the third light guide surface 102.

[0040] With this configuration, the light shining towards the back side inside the light guide head 1 will be redirected by the third light guide surface 102 due to the reflection and refraction of each surface, so that it shines upward as much as possible, resulting in a better light guiding effect. Meanwhile, the fixing block 1021 at the bottom ensures stability.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be included within the scope of protection of the present invention.
