Description

Technical Field

[0001] This utility model relates to the field of keycap technology, and in particular to a side-printed double-color keycap. Background Technology

[0002] Keycaps are components used to cover keyboard keys. They are made of plastic, silicone, and metal materials and serve both decorative and protective purposes. Keycap types include standard keycaps and custom keycaps. Some keycaps have anti-slip and backlighting functions, and their surfaces are designed with characters and patterns to help users identify keys and improve the typing experience. Keycaps are used in mechanical keyboards and membrane keyboards, providing convenience for keyboard use and aesthetic enhancement.

[0003] Side-printed keycaps solve the problems of character wear and inconvenience in low-light operation on mechanical keyboards. When using the keyboard for a long time, finger friction can cause the characters on the front to become blurred, making it even more difficult to identify the keys in low-light environments, thus affecting input efficiency. Side-printed keycaps use laser engraving and immersion filling processes to create clear characters on the side of the keycaps, and combine them with highly wear-resistant materials to enhance the durability of the characters. They can maintain the integrity of the characters during frequent use, accurately locate the keys in low-light environments, improve the smoothness and durability of keyboard operation, and are an important accessory for mechanical keyboards that combines personalization and practicality.

[0004] Traditional side-printed keycaps, due to structural design limitations, lack a defined design outline when adapted to keyboards. This makes it difficult to achieve a good match between the keycaps and keyboards with top and bottom LED backlights. Consequently, the keyboard backlight cannot be clearly projected through the keycap lettering, affecting the lighting display effect and user experience. In actual use, when faced with top and bottom LED backlights of different heights and angles, traditional side-printed keycaps, due to their structural design, cannot flexibly adapt to the differences in LED positions, resulting in the light being obstructed or unevenly projected, leading to visual problems such as poor lighting display effects.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a side-cut double-color keycap, including a base 1, a column base 2 fixedly connected to the top of the inner wall of the base 1, a light-transmitting mechanism 3 provided around the outer wall of the base 1, the light-transmitting mechanism 3 is used to allow the lighting effect to be displayed through the keycap, an installation mechanism 4 is provided at the bottom of the column base 2, a light-blocking mechanism 5 is provided on the inner wall of the base 1, the light-blocking mechanism 5 is used to prevent light from escaping and affecting the lighting effect, and a protective shell mechanism 6 is provided around the outer wall of the base 1.

[0034] The light-transmitting mechanism 3 includes multiple contours 31, which are fixedly connected to the bottom of the outer wall of the base 1. Multiple contours 32 are fixedly connected around the outer wall of the base 1. The bottom of the multiple contours 32 is fixedly connected to the top of the multiple contours 31. A contour 33 is fixedly connected to the top of the base 1. The outer wall of the contour 33 is fixedly connected to the top of the multiple contours 32. A light guide assembly 34 is provided on the top of the inner wall of the base 1.

[0035] Specifically, base 1 provides the installation foundation for the overall structure, column base 2 is fixedly connected to the top of the inner wall of base 1, and is used to cooperate with the installation mechanism 4 to assemble the keycaps and keyboard switches. The installation mechanism 4 is set at the bottom of column base 2, and through the connection with the keyboard switches, it fixes the entire keycap in the designated position of the keyboard. The protective shell mechanism 6 is set around the outer wall of base 1, and plays a protective role for base 1 and other external structures. The light blocking mechanism 5 is set on the inner wall of base 1, and is used to block the light from escaping, ensuring that the light can propagate along the preset path and avoid the light escaping from interfering with the lighting effect. The light transmission mechanism 3 is set around the outer wall and the top of the inner wall of base 1, and is used to guide the light to pass through, so as to realize the lighting display effect of the side-marked position.

[0036] Multiple contours 31 are fixedly connected to the bottom of the outer wall of the base 1. Multiple contours 32 are fixedly connected to the perimeter of the outer wall of the base 1, and the bottom of each contour 32 is fixedly connected to the top of each contour 31. Contour 33 is fixedly connected to the top of the base 1, and the outer wall of contour 33 is fixedly connected to the top of each contour 32. Through the connection of contours 31, 32, and 33, the basic structure of the side-etched area is formed around the perimeter of the outer wall of the base 1. The light guide assembly 34 is disposed on the top of the inner wall of the base 1. When light enters the interior of the base 1 from the outside, the light guide assembly 34 receives the light and guides it to the top and perimeter of the base 1. Under the guidance of the light guide assembly 34, the light propagates in the direction of contours 33, 32, and 31. Due to contours 31, Outline 2 32 and Outline 3 33 are connected sequentially to form a continuous structure, allowing light to be transmitted along the connecting path of these edges. Through the cooperation of Outline 1 31, Outline 2 32 and Outline 3 33, light can pass through the side-cut area to achieve the lighting display of the side-cut position. At the same time, the light-blocking mechanism 5 plays a role on the inner wall of the base 1, blocking the light from propagating in a non-preset direction and ensuring that the light is concentrated on the path guided by the light-transmitting mechanism 3. Through the guidance of the light guide component 34 and the structural cooperation of Outline 1 31, Outline 2 32 and Outline 3 33, the light is effectively transmitted through the side-cut area. The light-blocking mechanism 5 blocks the light, preventing light scattering and ensuring the stability of the lighting effect. Through the synergistic effect of the light-transmitting mechanism 3 and the light-blocking mechanism 5, a good lighting display effect of the side-cut double-color keycap is achieved.

[0037] Reference Figure 3 The light-blocking mechanism 5 includes a light-blocking layer 51. The outer wall of the light-blocking layer 51 is fixedly connected to the inner wall of the base 1. Two support ribs 52 are fixedly connected to each adjacent side of the inner wall of the light-blocking layer 51. A column hole 53 is opened at the top of the light-blocking layer 51. Protective components 54 are provided at the front and rear ends of the top of the inner wall of the light-blocking layer 51.

[0038] Specifically, the outer wall of the light-blocking layer 51 is fixedly connected to the inner wall of the base 1. This connection allows the light-blocking layer 51 to be stably installed on the base 1, providing basic support for the coordinated operation of subsequent components. Two support ribs 52 are fixedly connected to adjacent sides of the inner wall of the light-blocking layer 51. The fixed connection between the light-blocking layer 51 and the support ribs 52 enhances the structural strength of the light-blocking layer 51 and prevents deformation of the light-blocking layer 51 during operation. A column hole 53 is provided at the top of the light-blocking layer 51. The column hole 53 can be used to allow the installation mechanism 4 to pass through during installation and connect with the external structure. Protective components 54 are provided at the front and rear ends of the top of the inner wall of the light-blocking layer 51. The protective components 54 protect the relevant area of ​​the top of the inner wall of the light-blocking layer 51, preventing the area from being damaged during contact with other components or during operation. This achieves the effect of the light-blocking mechanism 5 stably and reliably playing its light-blocking role.

[0039] Reference Figure 3 and Figure 5 The installation mechanism 4 includes a column 3 41, the top of which is fixedly connected to the bottom of the column base 2. A cross groove 42 is provided at the bottom of the column 3 41. The bottom of the outer wall of the cross groove 42 is chamfered. The protective shell mechanism 6 includes a shell 1 61, the bottom of which is fixedly connected to the top of the base 1. A shell 2 62 is fixedly connected to the front side of the base 1. A shell 3 63 is fixedly connected to the rear side of the base 1. A shell 4 64 is fixedly connected to both the left and right sides of the base 1. The light guide assembly 34 includes a light guide post 1 341, the top of which is fixedly connected to the front end of the top of the inner wall of the base 1. A light guide post 2 342 is fixedly connected to the rear end of the top of the inner wall of the base 1.

[0040] Specifically, the top of column three 41 in the installation mechanism 4 is fixedly connected to the bottom of column base 2 and passes through column hole 53. A cross groove 42 is opened at the bottom of column three 41. The bottom of the outer wall of cross groove 42 is chamfered. Through the fixed connection between column three 41 and column base 2, and the chamfer design of cross groove 42, the column three 41 can be accurately connected and stably assembled with other components.

[0041] In the protective shell mechanism 6, the bottom of shell 1 61 is fixedly connected to the top of base 1, shell 2 62 is fixedly connected to the front side of base 1, shell 3 63 is fixedly connected to the rear side of base 1, and shell 4 64 is fixedly connected to both the left and right sides of base 1. Through the fixed connection of shell 1 61, shell 2 62, shell 3 63 and shell 4 64 with base 1, all-round protection of the internal structure of the device is formed, realizing the isolation and protection of internal components.

[0042] In the light guide assembly 34, the top of the first light guide post 341 is fixedly connected to the front end of the top of the inner wall of the base 1, and the rear end of the top of the inner wall of the base 1 is fixedly connected to the second light guide post 342. By fixing the first light guide post 341 and the second light guide post 342 to the top of the inner wall of the base 1, the directional guidance and propagation of light can be achieved.

[0043] The structural design of the mounting mechanism 4 ensures the stability of component assembly, the layout of the protective shell mechanism 6 forms a complete protection system, and the setting of the light guide component 34 realizes the light transmission function, realizes the compatibility of the keycap with the upper and lower light positions, and makes the lighting effect visible.

[0044] Reference Figure 3 , Figure 4 and Figure 5 The protective component 54 includes a column 1 541, the top of which is fixedly connected to the rear end of the top of the inner wall of the light-blocking layer 51, and a light hole 1 542 is opened at the bottom of the column 1 541. A column 2 543 is fixedly connected to the front end of the top of the inner wall of the light-blocking layer 51, and a light hole 2 544 is opened at the bottom of the column 2 543. A lower light position character 7 is fixedly connected to the front side of the base 1, and an upper light position character 8 is fixedly connected to the rear end of the top of the base 1. A lower light position character hole 9 is opened on the front side of the housing 2 62, and an upper light position character hole 10 is opened at the rear end of the top of the housing 1 61.

[0045] Specifically, the top of column 1 541 is fixedly connected to the rear end of the top of the inner wall of the light-blocking layer 51, and a light hole 542 is opened at the bottom of column 1 541 to allow light guide column 341 to pass through. Column 2 543 is fixedly connected to the front end of the top of the inner wall of the light-blocking layer 51, and a light hole 544 is opened at the bottom of column 2 543 to allow light guide column 342 to pass through. The lower lamp position character 7 is fixedly connected to the front side of the base 1, and the upper lamp position character 8 is fixedly connected to the rear end of the top of the base 1. The lower lamp position character hole 9 is opened on the front side of the housing 2 62, and the upper lamp position character hole 10 is opened at the rear end of the top of the housing 1 61.

[0046] Light can enter the base 1 through the light hole 542 at the bottom of column 1 and the light hole 544 at the bottom of column 2 543, forming a light path inside. The light acts on the upper light position character 8 at the rear end of the top of the base 1 and the lower light position character 7 at the front of the base 1, and is transmitted to form a character luminous effect. The light-blocking layer 51 fixes column 1 541 and column 2 543 to ensure the stable position of light hole 542 and light hole 544, avoiding the deviation of the light propagation path and the scattering of light. The corresponding setting of the upper light position character hole 10 at the rear end of the top of housing 1 61 with the upper light position character 8 allows the light reflected or transmitted by the upper light position character 8 to pass out through the upper light position character hole 10 and through the lower light position character 7 at the front of housing 2 62. The corresponding arrangement of the lower lamp position character 7 and the lower lamp position character hole 9 allows light reflected or transmitted through the lower lamp position character 7 to pass out through the lower lamp position character hole 9. Through the structural arrangement of the protective component 54 and the correspondence between each character and character hole, the effect of directional light transmission and external display is achieved. Through the front and rear distribution of column one 541 and column two 543 in the light-blocking layer 51, combined with the front and rear position differences of the upper lamp position character 8 and the lower lamp position character 7 on the base 1, the effect of independent display of characters in different positions is achieved. Through the light hole one 542 and light hole two 544 corresponding to the upper lamp position character 8 and the lower lamp position character 7 respectively, it is ensured that the light accurately acts on the target character. Through the correspondence between the character hole on the shell structure and the character, the effective transmission of display light is ensured.

[0047] Working principle: The base 1 provides the installation foundation for the overall structure. The column base 2 is fixedly connected to the top of the inner wall of the base 1 and is used to cooperate with the installation mechanism 4 to assemble the keycaps and keyboard switches. The installation mechanism 4 is set at the bottom of the column base 2 and, through its connection with the keyboard switches, fixes the entire keycap in the designated position on the keyboard. The protective shell mechanism 6 is set around the outer wall of the base 1 and plays a protective role for the base 1 and other external structures. The light blocking mechanism 5 is set on the inner wall of the base 1 and is used to block the light from escaping, ensuring that the light can propagate along the preset path and avoid the light escaping from interfering with the lighting effect. The light transmission mechanism 3 is set around the outer wall and the top of the inner wall of the base 1 and is used to guide the light to pass through, so as to realize the lighting display effect of the side-marked position.

[0048] The top of column 3 41 is fixedly connected to the bottom of column base 2 and passes through column hole 53. A cross groove 42 is opened at the bottom of column 3 41. The bottom of the outer wall of cross groove 42 is chamfered. Through the fixed connection between column 3 41 and column base 2, and the chamfer design of cross groove 42, the column 3 41 can be accurately connected and stably assembled with other components.

[0049] The bottom of housing 1 61 is fixedly connected to the top of base 1. Housing 2 62, housing 3 63 and housing 4 64 are fixedly connected to the front, rear and left and right sides of base 1, respectively. This connection method forms all-round protection for the internal structure of the device, effectively isolates internal components, and reduces interference and damage from external factors.

[0050] Multiple contours 1 31 are connected adjacent to each other on the bottom of the outer wall of the base 1. Multiple contours 2 32 are fixed around the outer wall of the base 1, and their bottoms are fixedly connected to the tops of contours 1 31. Contour 3 33 is fixed on the top of the base 1, and its outer wall is connected to the top of contour 2 32. Contours 1 31, contours 2 32 and contour 3 33 form the basic structure of the side-carved area around the outer wall of the base 1.

[0051] The light guide assembly 34 is set on the top of the inner wall of the base 1, including light guide post one 341 and light guide post two 342. The top of light guide post one 341 is fixed to the front end of the top of the inner wall of the base 1, and light guide post two 342 is fixed to the rear end of the top of the inner wall of the base 1. When external light enters the interior of the base 1, the light guide assembly 34 receives the light and guides the light to the top and all sides of the base 1 with its special structure. Under the guidance of the light guide assembly 34, the light propagates in the direction of contour three 33, contour two 32 and contour one 31. Since these three are connected in sequence to form a continuous structure, the light can be conducted along the connection path, realizing the compatibility of the keycap with the upper and lower light positions, and finally shines out from the side-printed area, presenting the lighting effect of the side-printed position.

[0052] The outer wall of the light-blocking layer 51 is fixedly connected to the inner wall of the base 1, providing stable support for the entire light-blocking mechanism 5. Two support ribs 52 are fixed on each adjacent side of the inner wall of the light-blocking layer 51. This not only enhances the structural strength of the light-blocking layer 51 and prevents it from deforming during operation, but also plays an auxiliary role in the light-blocking effect. A column hole 53 is opened at the top of the light-blocking layer 51 to facilitate the installation mechanism 4 to pass through and connect with the external structure. At the same time, protective components 54 are provided at the front and rear ends of the top of the inner wall of the light-blocking layer 51. This component consists of column one 541 and column two 543. The top of column one 541 is fixed to the rear end of the top of the inner wall of the light-blocking layer 51, and a light hole 542 is opened at the bottom to allow the light guide column to pass through. A light guide column 342 passes through the light-blocking layer 51; a light guide column 543 is fixed to the top front end of the inner wall of the light-blocking layer 51, and a light hole 544 is opened at the bottom to allow the light guide column 342 to pass through. The protective component 54 forms a protective barrier for the relevant area at the top of the inner wall of the light-blocking layer 51, preventing the area from being damaged when in contact with or working with other components. At the same time, it ensures the stability of the positions of the light hole 1 542 and the light hole 2 544, preventing the light propagation path from deviating and scattering. During the light propagation process, the light-blocking mechanism 5 blocks the light from propagating in a non-preset direction, ensuring that the light is concentrated on the path guided by the light transmission mechanism 3. Working together with the light transmission mechanism 3, it ensures the stability and accuracy of the lighting effect, and achieves a good lighting display effect for the side-carved double-color keycaps.

[0053] The keyboard backlight light enters the base 1 through the light hole 542 at the bottom of column 1 (541) and the light hole 544 at the bottom of column 2 (543), forming a light path inside. This light acts on the upper LED character 8 and the lower LED character 7, respectively, and is transmitted to create a character illumination effect. The light-blocking layer 51 secures column 1 (541) and column 2 (543), ensuring the stability of the light hole 542 and the light hole 544, preventing deviation of the light propagation path and light scattering. The upper LED character hole 10 at the top rear end of housing 1 (61) corresponds to the upper LED character 8, allowing light reflected or transmitted from the upper LED character 8 to pass outwards through the upper LED character hole 10. The lower LED character hole 9 on the front side of housing 2 (62) corresponds to the lower LED character 7. The light reflected or transmitted by the lower lamp position character 7 can be emitted outward through the lower lamp position character hole 9. This correspondence between the character and the character hole, combined with the structure of the protective component 54, achieves the effect of directional light transmission and external display. Through the front and rear distribution of column one 541 and column two 543 in the light-blocking layer 51, and the front and rear position differences of the upper lamp position character 8 and the lower lamp position character 7 on the base 1, the effect of independent display of characters in different positions is achieved. Light hole one 542 and light hole two 544 correspond to the upper lamp position character 8 and the lower lamp position character 7 respectively, ensuring that the light accurately acts on the target character. The correspondence between the character hole and the character on the shell structure ensures the effective transmission of display light, ultimately presenting an ideal lighting effect.
