[0033] like Figures 1 to 6 As shown, this utility model embodiment provides a push-pull linkage keyboard, including a keyboard body 1, a left cover 2 and a right cover 3. The left cover 2 and the right cover 3 are arranged opposite to each other and are slidably disposed on the keyboard body 1. The left cover 2 and the right cover 3 can move synchronously along the length direction of the keyboard body 1, and the movement directions of the left cover 2 and the right cover 3 are opposite. The key area 100 of the keyboard body 1 is exposed or covered by the movement of the left cover 2 and the right cover 3.
[0034] The key area 100 is equipped with conventional letter keys, function keys, and number keys. The left cover 2 and the right cover 3 are arranged opposite each other above the keyboard body 1. Both are slidably mounted on the keyboard body 1 and can slide along the length direction (i.e., the left and right direction) of the keyboard body 1.
[0035] The left cover 2 and right cover 3 move synchronously but in opposite directions. When the user pushes the left cover 2 to the left, the right cover 3 slides to the right simultaneously; conversely, when the user pushes the right cover 3 to the right, the left cover 2 slides to the left. Through this movement, the key area 100 of the keyboard body 1 can be exposed or obscured during the sliding of the left cover 2 and right cover 3. For example, when the user needs to use the keyboard, pushing the left cover 2 or right cover 3 separates them, fully exposing the key area 100 (i.e.,...). Figure 1 (In the middle state), to facilitate user input operations; after use, push one of the covers again to bring the left cover 2 and the right cover 3 closer together until they are completely closed (i.e., Figure 3 (In the state of being covered), thus blocking the button area 100 to prevent foreign objects such as dust, liquid, and debris from entering. In addition, since the left cover 2 and the right cover 3 are linked, only the left cover 2 or the right cover 3 needs to be operated, making the operation more convenient and smooth, and significantly improving the ease of use.
[0036] like Figure 2 and Figure 4 As shown, the linkage assembly includes a left rack 4, a right rack 5, and a gear shaft 6. The left rack 4 and right rack 5 are positioned at different heights, with the gear shaft 6 located between them. In actual assembly, one end of the left rack 4 is fixedly connected to the inside of the left cover 2, for example, by screws or adhesive. The other end of the left rack 4 extends along the length of the keyboard body 1 towards the right cover 3. One end of the right rack 5 is fixedly connected to the inside of the right cover 3, and the other end extends along the length of the keyboard body 1 towards the left cover 2. The gear shaft 6 is movably mounted on the keyboard body 1 via components such as bushings, and the teeth of the gear shaft 6 mesh with the teeth of the left rack 4 and right rack 5.
[0037] When the user pushes the left cover 2, the left cover 2 drives the left rack 4 to move to the left. The left rack 4 meshes with the gear shaft 6, causing the gear shaft 6 to rotate. The rotating gear shaft 6 then drives the right rack 5 to move to the right, thereby causing the right cover 3 to slide to the right, achieving synchronous reverse movement of the two.
[0038] In some embodiments, to ensure the stability and accuracy of the movement of the left cover 2, right cover 3, left rack 4, and right rack 5, such as... Figure 4 As shown, the keyboard body 1 has a left slide groove 131 and a right slide groove 132 arranged side by side along its length. The left rack 4 has a left support protrusion 41 that slides in conjunction with the left slide groove 131, and the right rack 5 has a right support protrusion 51 that slides in conjunction with the right slide groove 132. The left support protrusion 41 and the right support protrusion 51 can slide smoothly in the left slide groove 131 and the right slide groove 132, providing support and guidance for the movement of the left rack 4 and the right rack 5, and preventing them from deviating or jamming during movement.
[0039] The left slide groove 131 and the right slide groove 132 are located at the bottom of the mounting groove 13 and cooperate with the left support protrusion 41 and the right support protrusion 51 on the rack. They can not only guide the sliding direction of the left rack 4 and the right rack 5, but also provide stable support force during the movement of the left rack 4 and the right rack 5, disperse the lateral force generated during the movement, prevent the rack from twisting and deforming, and further ensure the smoothness and reliability of the synchronous reverse movement of the left cover 2 and the right cover 3.
[0040] like Figure 4 As shown, in some embodiments, the keyboard body 1 is further provided with a mounting groove 13, which extends along the length of the keyboard body 1. A left sliding groove 131 and a right sliding groove 132 are located at the bottom of the mounting groove 13, and the left sliding groove 131 and the right sliding groove 132 are distributed at different heights. The shape and size of the mounting groove 13 are designed according to requirements to meet the installation requirements of the left rack 4, the right rack 5, and the gear shaft 6.
[0041] The mounting slot 13 provides a dedicated mounting space for the linkage components, allowing the left rack 4, right rack 5, and gear shaft 6 to be compactly integrated inside the keyboard body 1. This avoids the problem of exposed components affecting the overall aesthetics and structural stability of the keyboard, while also reducing interference from the external environment on the transmission components.
[0042] like Figure 1 As shown, the keyboard body 1 also has a left movement guide groove 11 and a right movement guide groove 12 arranged side by side along its length. The left cover 2 has a left guide protrusion 221 that slides with the left movement guide groove 11, and the right cover 3 has a right guide protrusion that slides with the right movement guide groove 12. The cooperation of these guide protrusions and guide grooves further ensures the stability and accuracy of the left cover 2 and the right cover 3 during the sliding process.
[0043] In one embodiment, the left slide 131 and the right slide 132 are located on the front side of the keyboard body 1, and the left movement guide 11 and the right movement guide 12 are located on the rear side of the keyboard body 1. In another embodiment, the left slide 131 and the right slide 132 can also be located on the rear side of the keyboard body 1, and the left movement guide 11 and the right movement guide 12 can be located on the front side of the keyboard body 1, both of which can achieve good guiding effect.
[0044] like Figure 4As shown, both the left cover 2 and the right cover 3 include a top cover 21 and two side plates 22 located on the front and rear sides of the top cover 21. Taking the left cover 2 as an example, the left rack 4 and the left guide protrusion 221 are respectively located on the inner surfaces of the two side plates 22 of the left cover 2. The structure of the right cover 3 is similar to that of the left cover 2, with the right rack 5 and the right guide protrusion respectively located on the inner surfaces of the two side plates 22 of the right cover 3. This structural design allows the left cover 2 and the right cover 3 to better cooperate with the sliding grooves and guide grooves on the keyboard body 1 while ensuring strength.
[0045] In some embodiments, a left magnetic chuck may be provided on the side of the left cover 2 near the right cover 3, and a right magnetic chuck may be provided on the side of the right cover 3 near the left cover 2. When the left cover 2 and the right cover 3 are closed, the left and right magnetic chucks attract each other magnetically, making the closure tighter and preventing the covers from accidentally sliding open when not in use. For example, the left and right magnetic chucks may be small magnets, with magnetic strength sufficient to ensure the covers are securely closed while allowing the user to easily push the covers open.
[0046] In some embodiments, at least one of the surfaces of the left cover 2 and the right cover 3 may be provided with a display screen. The display screen is connected to the main control board of the keyboard body 1 via a cable and can display information such as the keyboard's working status, battery level, and connection mode. For example, a 1.5-inch OLED display screen is provided on the surface of the left cover 2 and connected to the main control board inside the keyboard body 1 via a flexible cable, allowing the user to view keyboard-related information at any time during use.
[0047] In summary, compared to traditional keyboard protective films and dust covers, this invention, when the left and right covers 3 are fully closed, can completely cover the key area 100, effectively preventing dust, liquids, debris, and other foreign objects from entering the keyboard, greatly improving its protective performance and extending its lifespan. For example, in a dusty office environment, the amount of dust accumulated inside the keyboard after one year using this invention is significantly less than that of a keyboard using a traditional dust cover. Furthermore, users only need to simply push the left cover 2 or the right cover 3 to expose or cover the key area 100, eliminating the need for frequent removal and placement like with traditional dust covers, significantly improving ease of use. Especially in scenarios involving frequent keyboard use and periods of inactivity, operational efficiency is greatly improved. In addition, the design of the gear and rack linkage component and multiple guiding structures ensures the smoothness and synchronization of the movement of the left cover 2 and the right cover 3, avoiding jamming and deviation during sliding, thus enhancing the user experience.
[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
