Description
Technical Field
[0001] This utility model relates to the field of keyboard switch technology, and in particular to a dual light guide column structure for a keyboard switch. Background Technology
[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. As keyboard manufacturing technology continues to develop, the lighting effect of the keyboard has become an important consideration. As the core component of the keyboard, the design of the key switch plays a key role in the lighting effect.
[0003] Currently, most keyboard switches on the market only have one light guide pillar installed on the switch body. A single light guide pillar can only be adapted to keyboards with a single direction of light position layout, making it difficult to achieve the ideal lighting effect and unable to adapt to the north-south light positions of different keyboards. Therefore, it is necessary to use a switch body mold with corresponding light positions, which increases the design cost. To address this, we propose a key switch dual light guide pillar structure. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual light guide pillar structure for key shafts. Its advantages lie in the fact that the two light guide pillars can be adapted to the north-south oriented LED positions of any keyboard, thereby saving costs, eliminating the need for additional molds, and preventing resource waste.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A key shaft dual light guide column structure includes a bottom cover and a top cover. The top cover has a first mounting groove on both the front and back sides. Light guide columns are installed inside the two first mounting grooves. A shaft assembly is provided on the top cover. Two locking mechanisms are provided on the shaft assembly. A cap assembly is provided on the shaft assembly, and the two locking mechanisms are fitted with the cap assembly.
[0007] The above technical solution involves installing two light guide pillars inside the two first mounting slots on the front and back of the top cover, respectively, so that the top cover has two light guide pillars, which can be adapted to the north-south light positions of any keyboard. By inserting the cover assembly into the switch assembly, the initial installation between the cover assembly and the switch assembly can be completed. When the cover assembly is inserted, it will squeeze the two locking mechanisms to retract. When the cover assembly no longer squeezes the two locking mechanisms, the two locking mechanisms will reset and lock the cover assembly, thereby strengthening the firmness of the cover assembly installed on the switch assembly.
[0008] The present invention is further configured such that two second mounting grooves are provided on the outer surface of the bottom cover, and the bottom ends of the two light guide pillars are respectively movably inserted into the interior of the second mounting grooves. The two light guide pillars are attached to the bottom cover and the top cover through the two second mounting grooves and the two first mounting grooves.
[0009] Through the above technical solution: the bottom cover and the top cover are combined together, so that the two light guide pillars inside the two first mounting slots on both sides of the top cover will be inserted into the two second mounting slots, so that the two second mounting slots can be attached to the outer surfaces of the bottom cover and the top cover, thus completing the installation of the two light guide pillars.
[0010] The present invention is further configured such that the shaft assembly includes a insert shaft and a shaft core, the insert shaft is connected inside the upper cover and extends to the top of the upper cover, and grooves are provided on both sides of the insert shaft, and the shaft core is connected inside the insert shaft.
[0011] By using the above technical solution, the key cover can be initially installed by inserting the cap assembly into the outer surface of the insert shaft and the shaft core.
[0012] The present invention is further configured such that the locking mechanism includes a connecting frame, a telescopic rod, an isosceles trapezoidal block and a spring. The connecting frame is connected to one side of the inner wall of the insert shaft, the telescopic rod is connected to one side of the inner wall of the connecting frame, and one end of the telescopic rod passes through one of the slots and extends to one side of the insert shaft. The isosceles trapezoidal block is connected to one end of the telescopic rod.
[0013] Through the above technical solution: when the key cover is fitted onto the outer surface of the insert shaft, it will squeeze the isosceles trapezoidal block to move into the interior of one of the slots, causing the telescopic rod to retract and the spring to compress. When the key cover no longer squeezes the isosceles trapezoidal block, the spring will return to its original position, causing the isosceles trapezoidal block to insert into the interior of one of the isosceles trapezoidal slots, locking the key cover and reinforcing the installation between the key cover and the insert shaft.
[0014] The present invention is further configured such that a spring is connected between one side of the isosceles trapezoidal block and one side of the inner wall of the connecting frame, and the spring is located outside the telescopic rod.
[0015] The above technical solution involves the isosceles trapezoidal block retracting into one of the slots and compressing the spring. When the spring returns to its original position, the isosceles trapezoidal block can be inserted into one of the isosceles trapezoidal slots, thereby locking the key cover.
[0016] The present invention is further configured such that the cap assembly includes a key cover and a mounting sleeve, the mounting sleeve being movably inserted into the outer surface of the shaft core, and the inner surface of the key cover being connected to the top of the mounting sleeve.
[0017] The above technical solution involves inserting the mounting sleeve into the outer surface of the shaft core, thereby allowing the key cover to be initially installed on the insert shaft.
[0018] The present invention is further configured such that two isosceles trapezoidal grooves are formed on the inner surface of the key cover, and the isosceles trapezoidal block is movably inserted into the interior of one of the isosceles trapezoidal grooves.
[0019] The above technical solution involves inserting an isosceles trapezoidal block into one of the isosceles trapezoidal slots to lock the key cover, thereby enhancing the stability of the key cover on the insert shaft.
[0020] The present invention is further configured such that buckles are connected to both sides of the upper cover and blocks are connected to both sides of the bottom cover, and the two buckles are respectively engaged and fixed with the two blocks.
[0021] With the above technical solution, when the bottom cover and the top cover are combined, the two locking blocks will lock the two buckles, thereby completing the installation between the bottom cover and the top cover.
[0022] The beneficial effects of this utility model are as follows:
[0023] 1. This utility model allows two light guide pillars to be installed inside the two first mounting slots on the bottom cover and the two second mounting slots on the top cover, and to fit against the outer surfaces of the bottom cover and the top cover. Therefore, it can be adapted to the north-south light positions of any keyboard, thereby saving costs, eliminating the need for additional molds and preventing resource waste.
[0024] 2. With the help of two locking mechanisms, this utility model not only strengthens the stability of the key cover installed on the insert shaft, but also facilitates the disassembly, replacement and maintenance of the key cover. This avoids the easy detachment of the key cover from the insert shaft in the traditional single-insertion installation, thereby improving the stability of the key cover installation and thus improving the practicality of the shaft assembly.

[0033] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0034] Reference Figures 1-7 A dual light guide pillar structure for a key switch includes a bottom cover 1 and a top cover 2. The top cover 2 has first mounting slots 3 on both its front and back sides. Light guide pillars 4 are installed inside each of the two first mounting slots 3. A key switch assembly 6 is mounted on the top cover 2, with two locking mechanisms 7 and a cap assembly 8. The two locking mechanisms 7 are fitted into the cap assembly 8. The two light guide pillars 4 are respectively installed inside the two first mounting slots 3 on the front and back sides of the top cover 2, giving the top cover 2 two light guide pillars 4, thus adapting to the north-south light positions of any keyboard. Initial installation between the cap assembly 8 and the key switch assembly 6 is completed by inserting the cap assembly 8 into the key switch assembly 6. Upon insertion, the cap assembly 8 compresses the two locking mechanisms 7, causing them to retract. When the cap assembly 8 no longer compresses the two locking mechanisms 7, the two locking mechanisms 7 reset, locking the cap assembly 8 and thus strengthening the secure installation of the cap assembly 8 onto the key switch assembly 6.
[0035] To install the two light guide pillars 4, refer to... Figures 1-2 Two second mounting slots 5 are provided on the outer surface of the bottom cover 1, and the bottom ends of the two light guide pillars 4 are respectively movably inserted into the interior of the second mounting slots 5. The two light guide pillars 4 are attached to the bottom cover 1 and the top cover 2 through the two second mounting slots 5 and the two first mounting slots 3, so that the bottom cover 1 and the top cover 2 are combined together. The two light guide pillars 4 in the two first mounting slots 3 on both sides of the top cover 2 will be inserted into the interior of the two second mounting slots 5, so that the two second mounting slots 5 are attached to the outer surface of the bottom cover 1 and the top cover 2, thus completing the installation of the two light guide pillars 4.
[0036] To install the key cover 801 onto the insert shaft 601, refer to... Figure 4 The keycap assembly 6 includes a plug 601 and a core 602. The plug 601 is connected inside the upper cover 2 and extends to the top of the upper cover 2. The plug 601 has grooves on both sides. The core 602 is connected inside the plug 601. The keycap 801 can be initially installed by inserting the cap assembly 8 into the outer surfaces of the plug 601 and the core 602.
[0037] To further strengthen the fixation of the key cover 801, refer to Figure 4 The locking mechanism 7 includes a connecting frame 701, a telescopic rod 702, an isosceles trapezoidal block 703, and a spring 704. The connecting frame 701 is connected to one side of the inner wall of the insert shaft 601, and the telescopic rod 702 is connected to one side of the inner wall of the connecting frame 701. One end of the telescopic rod 702 passes through one of the slots and extends to one side of the insert shaft 601. The isosceles trapezoidal block 703 is connected to one end of the telescopic rod 702. When the key cover 801 is fitted onto the outer surface of the insert shaft 601, it will press the isosceles trapezoidal block 703 to move into the interior of one of the slots, and cause the telescopic rod 702 to retract and the spring 704 to compress. When the key cover 801 no longer presses the isosceles trapezoidal block 703, the spring 704 will reset so that the isosceles trapezoidal block 703 is inserted into the interior of one of the isosceles trapezoidal slots 9, thereby locking the key cover 801 and reinforcing the installation between the key cover 801 and the insert shaft 601.
[0038] For easy locking and installation of the key cover 801, refer to... Figure 4 Spring 704 is connected between one side of isosceles trapezoidal block 703 and one side of the inner wall of connecting bracket 701, and spring 704 is located outside of telescopic rod 702. When isosceles trapezoidal block 703 is pressed by key cover 801, isosceles trapezoidal block 703 will retract into the interior of one of the slots and compress spring 704. When spring 704 returns to its original position, isosceles trapezoidal block 703 can be inserted into the interior of one of the isosceles trapezoidal slots 9, thereby locking key cover 801.
[0039] To install the keycap 801, refer to... Figure 4 The cap assembly 8 includes a key cover 801 and a mounting sleeve 802. The mounting sleeve 802 is movably inserted into the outer surface of the shaft core 602. The inner surface of the key cover 801 is connected to the top of the mounting sleeve 802. By inserting the mounting sleeve 802 into the outer surface of the shaft core 602, the key cover 801 can be initially installed on the insert shaft 601.
[0040] To lock the key cover 801, refer to... Figure 4 Figure 5 The inner surface of the key cover 801 has two isosceles trapezoidal grooves 9, and the isosceles trapezoidal block 703 is movably inserted into the inside of one of the isosceles trapezoidal grooves 9. By inserting the isosceles trapezoidal block 703 into the inside of one of the isosceles trapezoidal grooves 9, the key cover 801 can be locked, thereby strengthening the firmness of the key cover 801 installed on the insert shaft 601.
[0041] To connect the bottom cover 1 and the top cover 2, refer to... Figures 1-3Both sides of the upper cover 2 are connected with buckles 10, and both sides of the bottom cover 1 are connected with blocks 11. The two buckles 10 are engaged and fixed with the two blocks 11 respectively. When the bottom cover 1 and the upper cover 2 are combined, the two buckles 10 are locked by the two blocks 11, thus completing the connection and installation between the bottom cover 1 and the upper cover 2.
[0042] Working principle: The bottom cover 1 and top cover 2 are joined together by the latches 11 and latches 10 on both sides. The two latches 11 then lock the two latches 10 in place, completing the installation of the bottom cover 1 and top cover 2. Simultaneously, the two light guide pillars 4 inside the two first mounting slots 3 are inserted into the two second mounting slots 5, thus completing the installation of the two light guide pillars 4. This allows the position of the two light guide pillars 4 to adapt to the north-south light positions of any keyboard. When installing the key cover 801, align the mounting sleeve 802 with the switch core 602 and insert it onto the outer surface of the switch core 602. Then, continuously press the key cover 801 to lower it, causing the inside of the key cover 801 to compress the isosceles trapezoidal block 703 into one of the slots, allowing the telescopic rod 70 to extend. 2 will contract, and spring 704 will compress. When the position of one of the isosceles trapezoidal slots 9 is parallel to the position of isosceles trapezoidal block 703, key cover 801 will no longer press isosceles trapezoidal block 703, causing spring 704 to reset and telescopic rod 702 to extend, thereby allowing isosceles trapezoidal block 703 to move from one of the slots and insert into the interior of one of the isosceles trapezoidal slots 9, thus locking key cover 801 and completing the installation of key cover 801. When it is necessary to remove key cover 801 from insert shaft 601, simply pull key cover 801 upward with a larger force to press isosceles trapezoidal block 703 and withdraw it from the interior of one of the isosceles trapezoidal slots 9. At this time, key cover 801 can be removed from insert shaft 601, completing the disassembly work.
