Description

Technical Field

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

[0002] Mechanical keyboards are keyboards with a strong tactile feedback and a good user experience. Each key is controlled by an individual mechanical switch. To enhance the backlighting effect of the mechanical switches, LEDs are often placed inside the switches or on the circuit board, and the switches themselves are made semi-transparent to achieve the backlighting effect.

[0003] To enhance the lighting effect of LED lights, transparent light guides are now used in some products. These guides refract the LED light at different angles, making the buttons more aesthetically pleasing and appealing. However, this addition of light guides necessitates a larger overall size of the button shaft to meet these structural requirements, which is detrimental to the demand for thinner and lighter buttons. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a smaller shaft structure, which embeds the light guide column into the outer shell and base. This effectively saves space within the shaft, making the entire shaft structure thinner and lighter. In addition to achieving multi-angle light guiding, it also meets people's demand for a thinner and lighter shaft, thus improving the user experience.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] A smaller shaft structure includes a base and a housing disposed on the base, and a light guide post disposed between the housing and the base. One side of the base is recessed inward into the housing. The upper end of the housing has an upper insertion groove for inserting the upper end of the light guide post, and the lower end of the housing, located at the recessed position of the base, has a lower insertion groove that communicates with the upper insertion groove and for inserting the lower end of the light guide post. The light guide post is T-shaped in general, with its upper end being a transverse portion that inserts into the upper insertion groove and abuts against the upper side wall of the housing, and its lower end being a longitudinal portion that inserts into the lower insertion groove. The diameter of the transverse portion is larger than the diameter of the lower insertion groove.

[0007] As a further improvement of this utility model, at least one first lower limiting block is formed on the end of the longitudinal portion away from the base, and a first lower limiting groove is formed on the position of the outer shell located on the inner wall of the lower insertion groove, extending from bottom to top and for the first lower limiting block to be inserted.

[0008] As a further improvement of this utility model, a first inclined guide slope extending from the upper outer side to the lower inner side is formed on the outer side of the lower end of the first lower limit block.

[0009] As a further improvement of this utility model, at least one second lower limiting block protruding outward is formed on both sides of the longitudinal portion, and a second lower limiting groove extending from bottom to top and for the second lower limiting block to be inserted is formed on the position of the outer shell on the inner wall of the lower insertion groove.

[0010] As a further improvement of this utility model, a second inclined guide slope is formed on the outer side of the lower end of the second lower limit block, extending inclinedly from the upper outside to the lower inside.

[0011] As a further improvement of this utility model, the outer shell is provided with several external interference-fitting blocks that protrude inward and extend obliquely from the inside upward to the outside downward at the position of the inner wall of the lower insertion groove.

[0012] As a further improvement of this utility model, at least one inner interference block is formed on the outer wall of the base facing the direction of the lower insertion groove, which protrudes in the direction of the light guide column.

[0013] As a further improvement of this utility model, the upper end of the inner interference block is formed with an inner interference guide surface that extends obliquely from the inner upper part to the outer lower part.

[0014] The beneficial effects of this utility model are as follows:

[0015] The structure of this shaft includes a base and a housing disposed on the base, and a light guide post disposed between the housing and the base. One side of the base is recessed into the housing. The upper end of the housing has an upper insertion groove for the upper end of the light guide post to be inserted. The lower end of the housing, located at the recessed position of the base, has a lower insertion groove that communicates with the upper insertion groove and is for the lower end of the light guide post to be inserted. The light guide post is T-shaped in general. Its upper end is a horizontal part that is inserted into the upper insertion groove and abuts against the upper side wall of the housing. Its lower end is a vertical part that is inserted into the lower insertion groove. The diameter of the horizontal part is larger than the diameter of the lower insertion groove. By setting the base so that one side is recessed into the inner casing, space is saved between the base and the casing to form a lower insertion slot. The horizontal portion of the light guide post is placed in the upper insertion slot, and the vertical portion is placed in the lower insertion slot. This allows the light guide post to be installed within the casing and base without requiring additional space on the base to accommodate it. It also avoids increasing the overall height to accommodate the light guide post, allowing for a lower overall height and a thinner, lighter shaft structure. This not only enables multi-angle light guiding but also meets the demand for a slimmer shaft, improving the user experience. After the casing and base are interlocked, the light guide post can be directly inserted into the casing and base from above, facilitating assembly and improving production efficiency. Furthermore, the structure, with the horizontal portion's diameter larger than the lower insertion slot's diameter, ensures the horizontal portion is fully inserted into the slot. The bottom of the horizontal portion presses against the side wall of the casing, preventing it from falling into the lower insertion slot, thus limiting the light guide post's position and preventing it from falling out of the lower insertion slot.

[0033] Example 1

[0034] Please refer to Figures 1 to 7 This utility model embodiment provides a smaller shaft structure, including a base 1 and a shell 2 disposed on the base 1, and a light guide post 3 disposed between the shell 2 and the base 1. One side of the base 1 is recessed inward into the shell 2. The upper end of the shell 2 is provided with an upper insertion groove 21 for the upper end of the light guide post 3 to be inserted. The lower end of the shell 2, located at the recessed position of the base 1, is formed with a lower insertion groove 22 that communicates with the upper insertion groove 21 and is used for the lower end of the light guide post 3 to be inserted. The light guide post 3 is T-shaped in general. Its upper end is a horizontal part 31 that is inserted into the upper insertion groove 21 and abuts against the upper side wall of the shell 2. Its lower end is a vertical part 32 that is inserted into the lower insertion groove 22. The diameter of the horizontal part 31 is larger than the diameter of the lower insertion groove 22.

[0035] By setting the base 1 to be recessed into the inner shell 2 on one side, space is saved between the base 1 and the shell 2 to form a lower insertion groove 22. The horizontal part 31 of the light guide post 3 is inserted into the upper insertion groove 21, and the vertical part 32 is inserted into the lower insertion groove 22. This allows the light guide post 3 to be installed in the shell 2 and the base 1 without the need to set up additional space on the base 1 to accommodate the light guide post 3. It also avoids the situation where the overall height is increased in order to accommodate the light guide post 3, so the overall height can be reduced and the entire shaft structure can be made thinner. In addition to realizing multi-angle light guiding, it can also meet people's demand for a thin shaft and improve people's user experience. After the outer shell 2 and the base 1 are fastened together, the light guide post 3 can be directly inserted into the outer shell 2 and the base 1 from above, which facilitates assembly and effectively improves production efficiency. Furthermore, due to the structural setting that the diameter of the horizontal part 31 is larger than the diameter of the lower insertion groove 22, the horizontal part 31 is inserted into the groove 22 as a whole. The bottom end of the horizontal part 31 will press against the side wall of the outer shell 2, preventing it from falling into the lower insertion groove 22. This achieves the limitation of the light guide post 3 and prevents the light guide post 3 from falling out of the lower insertion groove 22.

[0036] To prevent the light guide post 3 from falling off the top of the outer shell 2, such as Figures 2 to 3 as well as Figures 5 to 7As shown, at least one first lower limiting block 321 protrudes outward from the end of the longitudinal portion 32 away from the base 1. A first lower limiting groove 23, extending upward from bottom to top and for the insertion of the first lower limiting block 321, is formed on the inner wall of the lower insertion groove 22 of the outer shell 2. The top of the first lower limiting groove 23 does not extend beyond the outer shell 2, meaning the first lower limiting groove 23 does not completely penetrate the inner wall of the outer shell 2. After the light guide post 3 is inserted from the top of the outer shell 2, the first lower limiting block 321 slides from the inner wall of the outer shell 2 into the first lower limiting groove 23 and is limited by the first lower limiting groove 23, thus pressing against the upper surface of the first lower limiting groove 23 and preventing it from moving upward further, effectively preventing the light guide post 3 from falling out from the top of the outer shell 2.

[0037] Preferred, such as Figures 2 to 3 as well as Figures 5 to 7 As shown, a first inclined guide slope 3211 is formed on the outer side of the lower end of the first lower limit block 321, extending inclinedly from the upper outside to the lower inside. When the first lower limit block 321 is installed, the first inclined guide slope 3211 first contacts the inner wall of the outer shell 2. Under the inclined guiding action of the first inclined guide slope 3211, the first lower limit block 321 can slide more easily into the groove 21 on the inner wall of the outer shell 2, thereby entering the first lower limit groove 23 to complete the purpose of limiting, and improve the accuracy and efficiency of installation.

[0038] Preferred, such as Figures 2 to 3 as well as Figures 5 to 7 As shown, an inclined inner wall surface 26 is formed on the inner sidewall of the outer shell 2, extending obliquely from the outer upper to the inner upper. When the first inclined guide slope 3211 of the first lower limit block 321 contacts the inclined inner wall surface 26, the inclined inner wall surface 26 and the first inclined guide slope 3211 cooperate with each other under the guiding action of both, making it easier for the first lower limit block 321 to slide upward into the groove 21 on the inner sidewall of the outer shell 2, thereby entering the first lower limit groove 23, completing the purpose of limiting, and improving the accuracy and efficiency of installation.

[0039] To make the light guide post 3 more stable within the lower insertion slot 22, such as Figures 2 to 3 as well as Figures 5 to 7As shown, the outer shell 2 has several external interference-fitting blocks 25 that protrude inward and extend obliquely from the upper inside to the lower outside on the inner wall of the lower insertion groove 22. When the longitudinal part 32 is inserted into the lower insertion groove 22, it moves downward along the external interference-fitting blocks 25. Due to the structure of the external interference-fitting blocks 25 extending obliquely from the upper inside to the lower outside, the pressure exerted on it by the external interference-fitting blocks 25 gradually increases. Combined with the limiting effect of the first lower limit block 321, the light guide column 3 is stably limited in the lower insertion groove 22.

[0040] To further stabilize the light guide post 3 within the lower insertion slot 22, such as Figures 4 to 5 as well as Figure 7 As shown, at least one inner interference block 11 is formed on the outer wall of the base 1 facing the lower insertion groove 22, protruding in the direction of the light guide column 3. When the longitudinal part 32 is inserted into the lower insertion groove 22, it presses against the inner interference block 11 and is squeezed by the inner interference block 11, thereby making the light guide column 3 more stable in the lower insertion groove 22 and ensuring the normal operation of the shaft.

[0041] Preferred, such as Figures 4 to 5 as well as Figure 7 As shown, the upper end of the inner interference block 11 has an inner interference guide surface 111 that extends obliquely from the upper inside to the lower outside. When the longitudinal part 32 is placed into the lower insertion groove 22, the lower end face of the longitudinal part 32 first contacts the inner interference guide surface 111. Under the oblique guiding action of the inner interference guide surface 111, the longitudinal part 32 can move more easily to the center of the lower insertion groove 22, thereby making the longitudinal part 32 more accurately and efficiently installed on the outer shell 2 and the base 1.

[0042] For other structures within the shaft, such as Figure 5 As shown, elements such as guide cores and springs are conventional technologies in this field, and their principles and structures are existing technologies, so they will not be described in detail in the embodiments.

[0043] Preferred, such as Figure 2 , Figure 5 As shown, in order to further save space in the shaft, a guide core relief groove is formed on the inner side of the light guide post 3 to match the guide core on the shaft. By setting the guide core relief groove to make way for the guide core, the structure inside the shaft is more compact, saving space inside the shaft and making the overall shaft structure thinner and lighter. In addition to realizing multi-angle light guiding, it can also meet people's demand for a thin and light shaft and improve people's user experience.

[0044] Preferred, such as Figures 2 to 3 as well as Figures 5 to 7As shown, a light-guiding inclined surface 323 extending obliquely from the upper outer side to the lower inner side is formed on the lower outer wall of the longitudinal part 32. By setting the light-guiding inclined surface 323, when the light guide post 3 is inserted, the light-guiding inclined surface 323 first contacts the inner side wall of the outer shell 2. Under the guiding action of the light-guiding inclined surface 323, the longitudinal part 32 is more easily inserted into the lower insertion groove 22, improving the accuracy and efficiency of installation.

[0045] Example 2

[0046] In the first embodiment, the structure of this shaft was described. This embodiment mainly focuses on the differences from other embodiments; identical structures will not be repeated in this embodiment.

[0047] like Figures 8 to 11 As shown, the main difference between Embodiment 2 and Embodiment 1 is that in this embodiment, at least one second lower limiting block 322 protruding outward is formed on both sides of the longitudinal portion 32. The outer shell 2 has a second lower limiting groove 24 extending upward from the bottom and for the second lower limiting block 322 to be inserted, located on the inner wall of the lower insertion groove 22. The top of the second lower limiting groove 24 does not extend beyond the outer shell 2, meaning the second lower limiting groove 24 does not completely penetrate the inner wall of the outer shell 2. After the light guide post 3 is inserted from the top of the outer shell 2, the second lower limiting block 322 on it slides from the inner wall of the outer shell 2 into the second lower limiting groove 24 and is limited by the second lower limiting groove 24, thus pressing against the upper surface of the second lower limiting groove 24 and preventing it from moving upward further, effectively preventing the light guide post 3 from falling out of the outer shell 2.

[0048] Preferred, such as Figures 8 to 11 As shown, a second inclined guide slope 3221 is formed on the outer side of the lower end of the second lower limit block 322, extending inclinedly from the upper outer side to the lower inner side. When the second lower limit block 322 is installed, the second inclined guide slope 3221 first contacts the inner sidewall of the outer shell 2. Under the inclined guiding action of the second inclined guide slope 3221, the second lower limit block 322 can more easily slide upward into the groove 21 on the inner sidewall of the outer shell 2, thereby entering the second lower limit groove 24 to complete the purpose of limiting, and improve the accuracy and efficiency of installation.

[0049] It should be noted that the smaller shaft structure disclosed in this utility model is an improvement on the specific structure, but the specific control method is not an innovation of this utility model. The guide core, spring, and other components involved in this utility model can be general standard parts or components known to those skilled in the art, and their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
