[0032] 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.

[0033] Please see Figure 1-4 This utility model provides a split keyboard structure, including a main keyboard 1;

[0034] The fixing component 2 located on the right side of the main keyboard 1 includes a fixing sleeve 21 located on the right side of the main keyboard 1; and a limiting component 24 slidably located inside the fixing sleeve 21.

[0035] The connecting component 3 is detachably located inside the fixing sleeve 21;

[0036] The secondary keyboard 4 is located on the right side of the connecting component 3.

[0037] In this embodiment, a split keyboard structure is provided. With the cooperation of the fixing component 2 and the connecting component 3, the main keyboard 1 and the secondary keyboard 4 can be stably connected, thereby avoiding the main keyboard 1 and the secondary keyboard 4 from shifting during use, which would affect the user's comfort.

[0038] Furthermore, such as Figure 2-3As shown, the fixing component 2 in the preferred embodiment of this utility model further includes a relief groove 22, which is formed on the upper surface of the fixing sleeve 21; and a relief hole 23, which is formed on the inner side of the relief groove 22.

[0039] Furthermore, the limiting component 24 includes a mounting block 241 slidably disposed inside the relief groove 22; a protrusion 242 disposed on the upper surface of the mounting block 241; a mounting groove 243 formed on the lower surface of the mounting block 241; a return spring 244 disposed between the inner side of the mounting groove 243 and the inner side of the relief groove 22; a limiting shaft 245 disposed on the lower surface of the mounting block 241, and the limiting shaft 245 is located inside the relief hole 23; and a plurality of limiting blocks 246 evenly distributed on the outer side of the limiting shaft 245.

[0040] Preferably, there are two fixing components 2, and the two fixing components 2 are symmetrically arranged on the right side of the main keyboard 1.

[0041] In this embodiment, several preferred embodiments of the fixing component 2 are given. By pulling the protrusion 242 upward, the protrusion 242 will drive the mounting block 241 to move upward. The mounting block 241 will stretch the return spring 244 and pull the limiting shaft 245 out from the inside of the fixing sleeve 21. Then the connecting component 3 can be placed into the inside of the fixing sleeve 21. Then the protrusion 242 is released. Under the action of the return spring 244, the mounting block 241 will drive the limiting shaft 245 into the connecting component 3, thereby connecting the main keyboard 1 and the secondary keyboard 4 together, thus ensuring the stability of the main keyboard 1 and the secondary keyboard 4 during use.

[0042] Furthermore, such as Figure 4 As shown, the connecting component 3 in the preferred embodiment of this utility model includes a connecting block 31, which is detachably disposed inside the fixing sleeve 21, and the sub-keyboard 4 is disposed on the right side of the connecting block 31; a connecting groove 32 is opened on the upper surface of the connecting block 31, and the limiting shaft 245 is located inside the connecting groove 32; a number of limiting grooves 33 are evenly distributed inside the connecting groove 32, and a number of limiting blocks 246 are located inside the number of limiting grooves 33.

[0043] Furthermore, the outer side of the limiting shaft 245 contacts the inner side of the connecting groove 32, and a number of limiting blocks 246 and a number of limiting grooves 33 are mutually adapted; the outer side of the connecting block 31 fits against the inner side of the fixing sleeve 21.

[0044] Preferably, there are two connecting components 3, which are respectively located inside the two fixed components 2, and the secondary keyboard 4 is located between the right sides of the two connecting components 3.

[0045] This embodiment provides several preferred embodiments of the connecting component 3. Through the connecting groove 32, when the limiting shaft 245 of the fixing component 2 enters the connecting groove 32, the secondary keyboard 4 can be stably positioned on the main keyboard 1, thus preventing the main keyboard 1 and secondary keyboard 4 from moving during use, which would reduce user comfort. Furthermore, by only engaging the rear fixing component 2 and the connecting component 3, the angle between the main keyboard 1 and secondary keyboard 4 can be adjusted before placing the limiting shaft 245 into the connecting groove 32. Then, the limiting shaft 245 is placed into the connecting groove 32, thereby securing the main keyboard 1. The main keyboard 1 and the secondary keyboard 4 are connected together, which creates a certain gap between them. This makes their relative positions more ergonomic, preventing excessive strain on the wrists and shoulders when using the main keyboard 1 and the secondary keyboard 4, thus reducing user fatigue. At the same time, with the cooperation of the limiting block 246 and the limiting groove 33, the main keyboard 1 and the secondary keyboard 4 will not rotate even when only the rearmost fixing component 2 and the connecting component 3 are in use, ensuring the stability of the main keyboard 1 and the secondary keyboard 4 during use.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
