Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, specifically to a mechanical keyboard board flat pressing device. Background Technology

[0002] A mechanical keyboard is a high-performance keyboard that uses mechanical switches as its core component, triggering keys through independent physical switches. Compared to traditional membrane keyboards, mechanical keyboards offer advantages such as longer key lifespan, stable key feel, and clear feedback, making them widely used in gaming, office, and professional equipment. The structure of a mechanical keyboard typically consists of keycaps, mechanical switches, a mounting plate (mechanical keyboard board), a PCB circuit board, and a casing, with the mounting plate playing a crucial role in the overall keyboard structure.

[0003] The mechanical keyboard plate, also known as the mounting plate, is a key support component of a mechanical keyboard, primarily used to fix the mounting position of the mechanical switches. The mounting plate has switch mounting holes to define the position of each key switch, ensuring neat and stable key alignment, while also providing additional structural strength and support. The presence of the mounting plate not only enhances the overall robustness of the keyboard but also plays a crucial role in the feel and feedback performance of the keys. Mechanical keyboard plates are typically made of metal materials (such as steel, stainless steel, or aluminum alloy) to ensure sufficient strength and durability.

[0004] However, during the production of the positioning plate, due to processes such as stamping, cutting, and transportation, the metal positioning plate is susceptible to external forces, resulting in slight plastic deformation. This deformation typically manifests as warping, bending, or surface unevenness. For mechanical keyboards, unevenness in the positioning plate shape will lead to the following problems:

[0005] 1. If the switch body is not properly secured during installation, it may affect the key rebound force and consistency of the feel.

[0006] 2. Gaps may appear when the positioning plate is attached to other components (such as the PCB board), reducing the assembly quality of the keyboard;

[0007] 3. During use, issues such as loose buttons or unusual noises may occur, severely impacting the user experience.

[0008] To ensure the flatness of the mechanical keyboard board, existing manufacturing processes typically require a dedicated flattening device to flatten the metal positioning plate. However, current flattening devices have certain shortcomings in practical use: they cannot quickly and accurately fix the positioning plate in place. If the positioning plate is misaligned, it will directly lead to uneven pressure application and distribution, thus affecting the flattening effect and potentially causing new deformation of the positioning plate during the flattening process.

[0009] Therefore, there is an urgent need in the existing technology for a flattening device that can quickly fix the metal positioning plate and ensure that it does not shift its position during the flattening process, so as to optimize the flattening process and improve the flatness of the mechanical keyboard board. In view of this, we propose a mechanical keyboard board flattening device. Utility Model Content

[0010] The purpose of this invention is to provide a mechanical keyboard board flat pressing device to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A mechanical keyboard flattening device includes a base, which supports the structural frame of the entire device, provides a stable mounting foundation, and provides fixation and support for a positioning component. The top of the base is provided with a detachable positioning component, which is used to place the mechanical keyboard to be flattened and can position the mechanical keyboard of the appropriate model to prevent displacement during the flattening process. The positioning component can be replaced to adapt to different models of mechanical keyboards, thereby giving the device a wide range of adaptability and meeting the flattening requirements of different keyboards.

[0013] The positioning assembly includes a placement plate, which is the main structure of the positioning assembly and is used to directly place the mechanical keyboard board to be flattened. Multiple circular slots are formed at the bottom of the placement plate near its outer edge. These slots are used to install springs and circular sliders, providing space and guidance for the movement of the positioning pins. Springs are installed within the circular slots, providing upward elastic force to the circular sliders, allowing the positioning pins to extend beyond the top of the slots. A circular slider is located at the top of the spring, serving as a support for the positioning pins. The spring force pushes the positioning pins upward. A positioning pin is located at the top of the circular slider, with its top end passing through the top of the inner wall of the circular slot to the outside. There are at least eight positioning pins, with at least two in each of the four directions (front, back, left, and right), thereby positioning the mechanical keyboard board placed on the placement plate and effectively preventing the keyboard board from shifting during the flattening process. During flattening, the positioning pins can move downwards, thus avoiding obstruction of the flattening plate.

[0014] The base has a U-shaped bracket at its top, which supports a hydraulic cylinder. The hydraulic cylinder is located in the middle of the top of the U-shaped bracket and is connected to an external hydraulic drive system. The hydraulic cylinder drives the movable plate to move up and down, providing a stable power source for the flattening process. The movable rod of the hydraulic cylinder passes through the top of the U-shaped bracket and is connected to the movable plate. The bottom of the movable plate is detachably connected to a flattening plate. The movable plate serves as a power transmission component for the hydraulic cylinder. By connecting to the flattening plate, the mechanical keyboard board on the positioning component is flattened. The flattening plate and the positioning component are a set. When the positioning component is replaced, the flattening plate also needs to be replaced to ensure that the flattening plate can effectively flatten the mechanical keyboard board, thereby adapting to different keyboard board models and meeting different flattening requirements.

[0015] Preferably, a rectangular positioning groove is provided in the middle of the top of the base, a base plate is provided at the bottom of the placement plate, and a rectangular positioning block is provided in the middle of the bottom of the base plate. The rectangular positioning block is inserted into the rectangular positioning groove. The insertion ensures the installation stability and accurate positioning of the positioning component, and also facilitates the replacement of the positioning component.

[0016] Preferably, the bottom of the base plate has multiple mounting holes a, and each mounting hole a is connected to a locking bolt. The threaded end of the locking bolt is threaded to the bottom of the placement plate to securely connect the base plate and the placement plate and confine the spring within the circular groove.

[0017] Preferably, the bottom of the movable plate has two rectangular holes arranged symmetrically from left to right, and the top of the movable plate is provided with a rectangular cover at the position of the two rectangular holes. The top of the rectangular cover has a mounting hole b in the middle, and the mounting hole b is connected to a fixing bolt. The flat plate is firmly fixed by the bolt connection.

[0018] Preferably, the top of the flat plate is provided with two rectangular mounting blocks arranged symmetrically from left to right. The rectangular mounting blocks pass through rectangular holes and are inserted into rectangular covers. The top of the rectangular mounting blocks is provided with threaded grooves for threaded connection of fixing bolts to facilitate the replacement of the flat plate.

[0019] Preferably, the top of the U-shaped bracket has two symmetrically arranged clearance holes. When the movable rod of the hydraulic cylinder is fully retracted, the rectangular cover passes through the clearance holes to avoid affecting the operation of the hydraulic cylinder.

[0020] Preferably, the top of the movable plate is provided with two positioning rods arranged symmetrically from left to right. The top of the positioning rods penetrates through the top of the inner wall of the U-shaped bracket to the outside, which is used to assist in positioning the position of the movable plate and ensure the stability of its up and down movement.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This mechanical keyboard board flattening device, by setting multiple positioning posts at the bottom of the placement plate, combined with the design of springs and circular sliders, achieves the positioning of the mechanical keyboard board. The positioning posts fix the keyboard board from four directions: front, back, left, and right, effectively preventing the keyboard board from shifting during the flattening process, improving the accuracy of the flattening process, and solving the problem of poor flattening effect caused by the misalignment of the positioning plate in the prior art.

[0023] 2.

[0035] Please see Figures 1-7 This utility model provides a technical solution:

[0036] A mechanical keyboard flattening device includes a base 1, which supports the structural frame of the entire device, provides a stable mounting base, and provides fixation and support for a positioning component 2. The top of the base 1 is provided with a detachable positioning component 2, which is used to place the mechanical keyboard to be flattened and can position the mechanical keyboard of the appropriate model to prevent displacement during the flattening process. The positioning component 2 can be replaced to adapt to different models of mechanical keyboards, thereby giving the device a wide range of adaptability and meeting the flattening requirements of different keyboards.

[0037] The positioning component 2 includes a placement plate 20, which is the main structure of the positioning component 2 and is used to directly place the mechanical keyboard board to be flattened. Multiple circular slots 200 are formed at the bottom of the placement plate 20 near its outer edge. These slots 200 are used to install springs 22 and circular sliders 23, providing space and guidance for the movement of the positioning post 24. Springs 22 are installed within the circular slots 200, providing upward elastic force to the circular sliders 23, allowing the positioning post 24 to extend beyond the top of the circular slots 200. The circular slider 23 is located at the top of the springs 22. The circular slider 23 serves as a support for the positioning post 24. The positioning post 24 is pushed upward by the elastic force of the spring 22. The top of the circular slider 23 is provided with the positioning post 24. The top of the positioning post 24 passes through the top of the inner wall of the circular groove 200 to the outside. There are at least 8 positioning posts 24, with at least two in each of the four directions: front, back, left, and right. This positions the mechanical keyboard board placed on the placement plate 20, effectively preventing the keyboard board from shifting during the flat pressing process. During the flat pressing process, the positioning post 24 can move downward to avoid obstructing the operation of the flat pressing plate 6.

[0038] The top of the base 1 is equipped with a U-shaped bracket 3, which supports the hydraulic cylinder 4. The hydraulic cylinder 4 is located in the middle of the top of the U-shaped bracket 3 and is connected to an external hydraulic drive system. The hydraulic cylinder 4 drives the movable plate 5 to move up and down, providing a stable power source for the flattening process. The movable rod of the hydraulic cylinder 4 passes through the top of the U-shaped bracket 3 and is connected to the movable plate 5. The bottom of the movable plate 5 is detachably connected to the flattening plate 6. The movable plate 5 serves as the transmission component for the output power of the hydraulic cylinder 4. By connecting to the flattening plate 6, the mechanical keyboard board on the positioning component 2 is flattened. The flattening plate 6 and the positioning component 2 are a set. When the positioning component 2 is replaced, the flattening plate 6 also needs to be replaced to ensure that the flattening plate 6 can effectively flatten the mechanical keyboard board, thereby adapting to different models of keyboard boards and meeting different flattening requirements.

[0039] In this embodiment, a rectangular positioning groove 10 is provided in the middle of the top of the base 1, and a base plate 21 is provided at the bottom of the placement plate 20. A rectangular positioning block 210 is provided in the middle of the bottom of the base plate 21. The rectangular positioning block 210 is inserted into the rectangular positioning groove 10. The insertion ensures the installation stability and accurate positioning of the positioning component 2, and also facilitates the replacement of the positioning component 2.

[0040] Specifically, the bottom of the base plate 21 has multiple mounting holes a211, and the mounting holes a211 are connected to locking bolts 25. The threaded end of the locking bolts 25 is threaded to the bottom of the placement plate 20 to securely connect the base plate 21 and the placement plate 20 and restrict the spring 22 within the circular groove 200.

[0041] Furthermore, the bottom of the movable plate 5 has two rectangular holes 50 arranged symmetrically from left to right. The top of the movable plate 5 is provided with a rectangular cover 51 at the position of the two rectangular holes 50. The top center of the rectangular cover 51 has a mounting hole b510, and the mounting hole b510 is connected with a fixing bolt 7. The flat plate 6 is firmly fixed by bolt connection.

[0042] Furthermore, the top of the flat plate 6 is provided with two rectangular mounting blocks 60 arranged symmetrically on the left and right. The rectangular mounting blocks 60 pass through the rectangular holes 50 and are inserted into the rectangular cover 51. The top of the rectangular mounting blocks 60 is provided with threaded grooves 600 for the threaded connection of the fixing bolts 7, which facilitates the replacement of the flat plate 6.

[0043] Furthermore, the top of the U-shaped bracket 3 has two symmetrically arranged clearance holes 30. When the movable rod of the hydraulic cylinder 4 is fully retracted, the rectangular cover 51 passes through the clearance holes 30 to avoid affecting the operation of the hydraulic cylinder 4.

[0044] Furthermore, the top of the movable plate 5 is provided with two positioning rods 52 arranged symmetrically on the left and right. The top of the positioning rods 52 penetrates through the top of the inner wall of the U-shaped bracket 3 to the outside, which is used to assist in positioning the position of the movable plate 5 and ensure its stability in vertical movement.

[0045] In this embodiment, when the mechanical keyboard board flat pressing device is in use, firstly, the positioning component 2 is inserted into the rectangular positioning groove 10 on the top of the base 1 through the rectangular positioning block 210 set on the bottom plate 21. The rectangular positioning groove 10 can ensure that the positioning component 2 is accurately positioned.

[0046] Next, the mechanical keyboard board to be flattened is placed on the placement plate 20 of the positioning component 2. Since the placement plate 20 is equipped with multiple positioning posts 24, it can automatically perform multi-point positioning of the keyboard board to ensure that the keyboard board will not shift during placement. The positioning posts 24 are distributed in multiple directions, front, back, left and right, which can accurately fix the keyboard board and provide stable support for the subsequent flattening operation. At this time, the keyboard board has been stably fixed in the device and is in the state of waiting to be flattened.

[0047] Start hydraulic cylinder 4, which drives movable plate 5 to move downward through its movable rod. The bottom of movable plate 5 is connected to flat pressure plate 6. As movable plate 5 descends, flat pressure plate 6 gradually contacts the surface of keyboard board. During the flattening process, positioning pin 24 moves downward under the pressure of flat pressure plate 6, thereby avoiding obstruction to the movement of flat pressure plate 6. With further drive of hydraulic cylinder 4, flat pressure plate 6 applies uniform pressure to keyboard board, correcting the deformation of keyboard board surface to flatness.

[0048] After flattening is completed, the movable rod of the hydraulic cylinder 4 retracts upward, causing the movable plate 5 and the flat plate 6 to rise. After the flat plate 6 rises, the positioning column 24 will extend out of the top of the circular groove 200 under the elastic force of the spring 22, restoring the positioning function of the keyboard board. At this time, the keyboard board that has been calibrated can be safely removed. If it is necessary to replace other models of keyboard boards, only the matching positioning component 2 and the flat plate 6 need to be replaced. The modular design of the device can quickly adapt to different models of keyboard boards, thereby meeting various production needs.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
