Technical Field
[0001] This utility model relates to the field of mechanical keyboard technology, specifically a three-mode mechanical keyboard with a wrist rest. Background Technology
[0002] A mechanical keyboard is a type of keyboard. Structurally, each key on a mechanical keyboard has an individual switch to control its closure. This switch is also called a "switch". According to the classification of microswitches, mechanical keyboards can be divided into traditional brown switches, blue switches, white switches, black switches, red switches, as well as Romer-G and optical switches.
[0003] Currently, mechanical keyboards offer many advantages over traditional keyboards, such as superior tactile feedback and greater durability. Furthermore, different switch types, such as white, black, blue, brown, and red, provide users with diverse tactile experiences. Therefore, mechanical keyboards are widely popular. To enhance user comfort, mechanical keyboards often incorporate a wrist rest. However, existing wrist rests are fixed to the side of the keyboard and cannot be disassembled or folded, leading to increased size and inconvenience for portability. Therefore, this invention proposes a three-mode mechanical keyboard with a wrist rest. Utility Model Content
[0004] The purpose of this utility model is to provide a three-mode mechanical keyboard with a wrist rest to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a three-mode mechanical keyboard with a wrist rest, comprising a keyboard body, a first groove on the keyboard body, and a wrist rest structure installed in the first groove; the wrist rest structure includes a tray installed inside the first groove, a sliding shaft fixedly connected to the tray and slidably connected to the keyboard body, a sliding groove adapted to the sliding shaft on the keyboard body, and a rotating shaft rotatably connected to the tray, with a support plate fixedly connected to the rotating shaft and installed inside the first groove; it also includes a limiting component, which is installed inside the tray and connected to the sliding shaft, and is used to limit the position of the tray; and a fixing component, which is installed on the tray and connected to the rotating shaft, and fixes the support plate by fixing the rotating shaft, facilitating the storage of the wrist rest structure, thereby achieving a wrist rest structure on the keyboard body without affecting the volume of the keyboard body.
[0005] Preferably, the limiting component includes limiting rods slidably mounted on both ends of the sliding shaft. The limiting rods are inserted into the keyboard body. A first slot and a second slot adapted to the limiting rods are respectively opened at both ends of the sliding groove in the keyboard body. A spring fixedly connected to the sliding shaft is fixedly connected to the end of the limiting rod, and a connecting rod slidably connected to the sliding shaft is also fixedly connected to the end of the limiting rod. A pulling member for pulling the limiting rod is installed between the two sets of connecting rods to facilitate limiting the position of the tray. The tray can be pulled out when in use and retracted to the bottom of the keyboard body when not in use.
[0006] Preferably, the pulling member includes a sliding rod that is fixedly connected to the two sets of connecting rods respectively. The sliding rod is slidably connected to the support plate, and the support plate has a movable groove adapted to the sliding rod. The end of the sliding rod is fixedly connected to a toggle piece, which facilitates pulling the limiting rod to move, so that the limiting rod can switch positions inside the first slot and the second slot.
[0007] Preferably, the fixing assembly includes a fixing frame fixedly connected to the tray, a pressing rod slidably connected to the fixing frame and pressingly engaged with the rotating shaft, a prismatic column fixedly connected to the end of the pressing rod, a threaded column internally threaded to the prismatic column, a handle fixedly connected to the end of the threaded column, a fixing sleeve rotatably connected to the handle and fixedly connected to the fixing frame, the fixing sleeve being slidably connected to the prismatic column, facilitating the fixing of the support plate, and supporting the tray through the support plate to ensure the stability of the tray.
[0008] Preferably, a first magnetic strip is installed on the support plate, and a second magnetic strip is installed on the keyboard body, which is positioned corresponding to the first magnetic strip. When the wrist rest structure is not used, it is convenient to fit the support plate into the first groove.
[0009] Preferably, the end of the limiting rod is tapered to facilitate insertion of the limiting rod into the first slot and the second slot.
[0010] Preferably, a second groove is provided on the tray at the position of the toggle piece, and the end of the tray is set below the depth of the second groove, so that the toggle piece will not protrude from the bottom of the keyboard body, ensuring the stability of the keyboard during use.
[0011] Preferably, the end of the extrusion rod is provided with an anti-slip pad, which facilitates increasing the friction between the extrusion rod and the rotating shaft, thereby improving the stability of the support plate.
[0012] This utility model has at least the following beneficial effects:
[0013] This utility model provides a three-mode mechanical keyboard with a wrist rest. During use, two sets of toggle switches pull two sets of sliding rods and a connecting rod, which in turn move two sets of limiting rods, causing them to move away from the second slot. The sliding groove and sliding shaft then allow the support plate to slide. When the limiting rod aligns with the first slot, the wrist rest extends out of the keyboard body. The support plate is then rotated to fit against the desktop, and a fixing component secures it. Thus, the wrist rest provides support. When not in use, the toggle switches are pulled again... The moving plate causes the two sets of limiting rods to move again and move them into the second slot. Then, the fixing component is released, and the support plate is rotated to reset the support plate. Finally, the tray and support plate are placed inside the first groove on the keyboard body, which facilitates the storage of the wrist rest structure and avoids the increase in the size of the keyboard body due to the presence of the wrist rest structure. Therefore, the wrist rest structure can be added to the keyboard body through the function of the limiting component and the fixing component, and it is easy to store the wrist rest structure. This solves the problem in the prior art that the wrist rest structure on the keyboard body increases the size of the keyboard body and makes it inconvenient to carry. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0026] Please see Figures 1-10 This utility model provides a technical solution: a three-mode mechanical keyboard with a wrist rest, comprising a keyboard body 1, a first groove 2 on the keyboard body 1, and a wrist rest structure 28 installed in the first groove 2; the wrist rest structure 28 includes a support plate 3 installed inside the first groove 2, a sliding shaft 4 fixedly connected to the support plate 3 and slidably connected to the keyboard body 1, a sliding groove 5 adapted to the sliding shaft 4 on the keyboard body 1, and a rotating shaft 6 rotatably connected to the support plate 3, the rotating shaft 6 being fixedly connected to a... The first groove 2 includes an internal support plate 7; it also includes a limiting component 8, which is installed inside the tray 3 and connected to the sliding shaft 4, and the limiting component 8 is used to limit the position of the tray 3; and a fixing component 9, which is installed on the tray 3 and connected to the rotating shaft 6, and the fixing component 9 fixes the support plate 7 by fixing the rotating shaft 6, so as to facilitate the storage of the wrist rest structure 28, thereby realizing the structure of the keyboard body 1 having a wrist rest without affecting the volume of the keyboard body 1.
[0027] In this solution, during use, the tray 3 is pulled out and used. The tray 3 is limited by the limiting component 8, and then the tray 3 is supported by the supporting plate 7. The supporting plate 7 is fixed by the fixing component 9, thereby supporting the user's wrist through the action of the tray 3 and the supporting plate 7.
[0028] In this solution, when not in use, the tray 3 and the support plate 7 are pushed back into the first groove 2 to store the support plate 7 and the tray, thus avoiding an increase in the volume of the keyboard body 1 after adding the wrist rest structure 28.
[0029] The limiting assembly 8 includes limiting rods 10 slidably mounted at both ends of the sliding shaft 4. The limiting rods 10 are inserted into the keyboard body 1. A first slot 11 and a second slot 12, adapted to the limiting rods 10, are respectively provided at both ends of the sliding groove 5 in the keyboard body 1. A spring 13, fixedly connected to the sliding shaft 4, is fixedly connected to the end of the limiting rod 10. A connecting rod 14, slidably connected to the sliding shaft 4, is also fixedly connected to the end of the limiting rod 10. A mechanism for pulling the limiting rods 10 is installed between the two sets of connecting rods 14. The pull member 15 facilitates the positioning of the tray 3, allowing the tray 3 to be pulled out during use and retracted to the bottom of the keyboard body 1 when not in use. The pull member 15 includes a sliding rod 16 fixedly connected to two sets of connecting rods 14 respectively. The sliding rod 16 is slidably connected to the tray 3, and the tray 3 has an active groove 17 adapted to the sliding rod 16. The end of the sliding rod 16 is fixedly connected to a toggle piece 18, which facilitates the movement of the limiting rod 10, allowing the limiting rod 10 to switch positions inside the first slot 11 and the second slot 12.
[0030] In this scheme, during use, pulling the two sets of actuating plates 18 causes the sliding rod 16 to move the connecting rod 14. The movement of the connecting rod 14 causes the limiting rod 10 to move. When the limiting rod 10 moves, it will compress the spring 13 and move the limiting rod 10 away from the second slot 12. Then, through the action of the sliding shaft 4 and the sliding groove 5, the limiting rod 10 moves to correspond with the first slot 11. At this time, the spring 13 resets the limiting rod 10 into the first slot 11. At this time, the position of the tray 3 is limited by the action of the limiting rod 10 and the first slot 11.
[0031] In this solution, after use, the two sets of levers 18 are pulled again, and the limiting rod 10 will disengage from the first slot 11. Then, the tray 3 is slid again so that the tray 3 is placed inside the first groove 2 to store the tray 3. Then, the tray 3 is limited by the action of the limiting rod 10 and the second slot 12.
[0032] The fixing assembly 9 includes a fixing frame 20 fixedly connected to the tray 3. A pressing rod 21 that is pressed against the rotating shaft 6 is slidably connected to the fixing frame 20. A prismatic column 22 is fixedly connected to the end of the pressing rod 21. A threaded column 23 is internally threaded to the prismatic column 22. A handle 24 is fixedly connected to the end of the threaded column 23. A fixing sleeve 25 fixedly connected to the fixing frame 20 is rotatably connected to the handle 24. The fixing sleeve 25 is slidably connected to the prismatic column 22 to facilitate the fixing of the support plate 7. The support plate 7 supports the tray 3 and ensures the stability of the tray 3.
[0033] In this solution, during use, the support plate 7 is rotated to make it fit against the table. Then, the handle 24 is turned, which drives the threaded column 23 to rotate. The threaded column 23 drives the prismatic column 22 to move, which in turn drives the pressing rod 21 to move and press the rotating shaft 6. This presses and fixes the rotating shaft 6 and the support plate 7. The support plate 7 supports the tray 3 and maintains its stability.
[0034] In this solution, after use, the handle 24 is rotated in the opposite direction to make the squeezing rod 21 move away from the rotating shaft 6. At this time, the support plate 7 is flipped to reset. Then, the two sets of actuating plates 18 are pulled to make the limiting rod 10 move away from the first slot 11. Then, the sliding groove 5 makes the tray 3 slide into the first groove 2. The support plate 7 will also move into the first groove 2, which makes it easy to store the support plate 7 and the tray 3 and make them easy to carry.
[0035] In this design, a first magnetic strip 26 is installed on the support plate 7, and a second magnetic strip 27 corresponding to the position of the first magnetic strip 26 is installed on the keyboard body 1. When the wrist rest structure 28 is not used, the mutual attraction between the first magnetic strip 26 and the second magnetic strip 27 facilitates the fitting of the support plate 7 into the first groove 2. The end of the limiting rod 10 is tapered, which facilitates the insertion of the limiting rod 10 into the first slot 11 and the second slot 12. A second groove 19 is provided on the tray 3 at the position of the toggle piece 18. The end of the tray 3 is set lower than the depth of the second groove 19, so that the toggle piece 18 will not protrude from the bottom of the keyboard body 1, ensuring the stability of the keyboard during use. The end of the pressing rod 21 is provided with an anti-slip pad, which facilitates the increase of friction between the pressing rod 21 and the rotating shaft 6, thereby improving the stability of the support plate 7.
[0036] Working principle: During use, pulling the two sets of actuating plates 18 causes the sliding rod 16 to move the connecting rod 14. The movement of the connecting rod 14 causes the limiting rod 10 to move. When the limiting rod 10 moves, it compresses the spring 13, causing the limiting rod 10 to move away from the second slot 12. Then, through the action of the sliding shaft 4 and the sliding groove 5, the limiting rod 10 moves to correspond with the first slot 11. At this time, the spring 13 resets the limiting rod 10 and inserts it into the first slot 11. Inside 1, the position of the tray 3 is limited by the action of the limiting rod 10 and the first slot 11. Then, the support plate 7 is rotated to make the support plate 7 fit against the table. Then, the handle 24 is turned. The rotation of the handle 24 drives the threaded column 23 to rotate. The action of the threaded column 23 drives the prismatic column 22 to move. Then, the prismatic column 22 drives the pressing rod 21 to move and press the rotating shaft 6, thereby pressing and fixing the rotating shaft 6 and the support plate 7. The support plate 7 supports the tray 3 and maintains the stability of the tray 3.
[0037] After use, pull the two sets of levers 18 again, and the limiting rod 10 will disengage from the first slot 11. Then, slide the tray 3 again so that the tray 3 is placed inside the first groove 2 for storage. Then, the limiting rod 10 and the second slot 12 limit the tray 3. Then, turn the handle 24 in the opposite direction so that the pressing rod 21 moves away from the rotating shaft 6. At this time, flip the support plate 7 to reset. Then, pull the two sets of levers 18 so that the limiting rod 10 moves away from the first slot 11. Then, the sliding groove 5 makes the tray 3 slide into the first groove 2. The support plate 7 will also move into the first groove 2, so that the support plate 7 and the tray 3 can be stored and carried easily.
