[0023] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a portable folding wireless keyboard, including a left keyboard 1 and a right keyboard 2. Among them, in order to ensure the normal use of the wireless keyboard, a number of physical keys are installed on the upper surfaces of the left keyboard 1 and the right keyboard 2;

[0024] The left keyboard 1 and the right keyboard 2 are movably hinged through a hinge 3. Specifically, refer to the attached Figure 2 As shown, the movable connection through the hinge 3 can ensure the normal unfolding and folding and closing effects between the left keyboard 1 and the right keyboard 2, which is convenient for folding and storing and ensures the normal portable folding use of the keyboard;

[0025] Among them, in order to limit and lock the two groups of keyboards in the folded state, two symmetrically distributed insertion slots 9 are opened on the outer wall of one side of the bottom end of the left keyboard 1. A locking post 10 is movably inserted on the side wall of the insertion slot 9. The tail end of the locking post 10 is fixedly connected to a rear end cap 11. A return spring 12 is fixedly installed on the outer wall of the rear end cap 11. The other end of the return spring 12 is fixedly connected to the outer wall of the left keyboard 1, and the return spring 12 is sleeved outside the locking post 10;

[0026] With this structural design, the user can manually pull the locking post 10 through the rear end cap 11, so that the locking post 10 moves outward from the keyboard. During the manual pulling of the rear end cap 11, it will stretch the tension spring 12. After releasing, the tension spring 12 can reset, so that the spring drives the locking post 10 to reset;

[0027] On the outer wall of one side of the right keyboard 2, two storage grooves 5 adapted to the insertion grooves 9 are provided. A locking block 7 is rotatably installed in the storage groove 5 through a rotating shaft 6. A locking hole 8 is provided on the outer surface of the locking block 7. The rotating shaft 6 is rotatably connected to the storage groove 5 of the right keyboard 2, and the locking block 7 is fixedly sleeved outside the rotating shaft 6;

[0028] According to the above structure, when the left and right keyboards need to be folded, the left and right keyboards can be manually bent downward, so that the left and right keyboards can be folded and rotated along the hinge 3, thus completing the folding work;

[0029] When the locking and limiting in the folded state is required, the locking block 7 inside the storage groove 5 can be manually bent, so that the locking block 7 rotates 90°. At this time, the locking block 7 is in a vertical state (shown in the instruction manual as the horizontal storage state), that is, the locking block 7 is perpendicular to the storage groove 5. At this time, the left and right keyboards are folded; Figure 2 and Figure 3 After the left and right keyboards are folded, the vertically placed locking block 7 will be inserted into the insertion groove 9. At this time, manually pull the rear end cap 11 outward. During the pulling process of the rear end cap 11, it will drive the locking post 10 to move outward from the keyboard. At the same time, during the outward movement of the locking post 10, the rear end cap 11 will stretch the tension spring 12;

[0030] When the locking post 10 moves outward and is received into the hole, press the left and right keyboards to completely fold and close them, and the locking block 7 will also be completely inserted into the insertion groove 9. In this state, the locking hole 8 will be aligned with the locking post 10. Then release the rear end cap 11. After the tension spring 12 in the stretched state has no external pulling force, it will elastically reset, so as to drive the locking post 10 to move in the direction of the right keyboard 2, so that the locking post 10 is inserted into the locking hole 8 of the locking block 7, thus completing the positioning and locking work of the keyboard in the folded state through the effect of positioning insertion.

[0031] In this embodiment, in order to ensure that the locking post 10 can be smoothly inserted into the locking hole 8, the aperture of the locking hole 8 is larger than the diameter of the locking post 10.

[0032]

[0033] ​In this embodiment, anti-slip pads 13 are adhesively attached to the outer walls of the lower surfaces of the left keyboard 1 and the right keyboard 2 by glue. The anti-slip pads 13 are rubber anti-slip pads. By providing the anti-slip pads 13, the anti-slip property of the keyboard in contact with the desktop can be improved, and the stability of the keyboard during use can be enhanced.

[0034] In this embodiment, specifically refer to the attached drawings of the specification Figure 1 As shown, magnetic attraction strips 4 adapted to each other are fixedly installed on the outer walls of the hinge 3 connection parts of the left keyboard 1 and the right keyboard 2. By providing the magnetic attraction strips 4, left and right magnetic attraction processing can be performed when the left keyboard 1 and the right keyboard 2 are unfolded for use, so as to have a certain magnetic attraction connectivity. When folding, it can also have a certain folding damping effect, avoiding the situation that the left keyboard 1 and the right keyboard 2 automatically fold when picked up due to the hinge 3 being too flexible, improving the structural usability of the keyboard in the unfolded state and having a certain magnetic attraction damping effect.

[0035] Working principle: The left keyboard 1 and the right keyboard 2 of the present utility model are movably hinged through a hinge 3. Specifically refer to the attached drawings of the specification Figure 2 As shown, the movable connection through the hinge 3 can ensure the normal unfolding and folding and closing effects between the left keyboard 1 and the right keyboard 2, facilitating folding and storage, and ensuring the normal folding and carrying use of the keyboard;

[0036] When it is necessary to fold the left and right keyboards, the left and right keyboards can be manually bent downward, so that the left and right keyboards can be folded and rotated along the hinge 3, thereby completing the folding work;

[0037] When it is necessary to lock and limit in the folded state, the locking block 7 inside the storage groove 5 can be manually bent, so that the locking block 7 rotates 90°. At this time, the locking block 7 is in a vertical state (shown in the attached drawings of the specification Figure 2 and Figure 3 as the horizontal storage state), that is, the locking block 7 is perpendicular to the storage groove 5. At this time, the left and right keyboards are folded;

[0038] After the left and right keyboards are folded, the vertically state locking block 7 will partially insert into the insertion slot 9. Due to the blockage of the locking column 10, it does not completely insert. At this time, manually pull the rear end cap 11 outward. During the pulling process of the rear end cap 11, it will drive the locking column 10 to move outward of the keyboard. At the same time, during the outward movement of the locking column 10, the rear end cap 11 will stretch the return spring 12;

[0039] When the locking column 10 moves outward and is received into the hole inside the side of the insertion slot 9, at this time, press the left and right keyboards to fold and close them completely, and the locking block 7 will also be completely inserted into the insertion slot 9. In this state, the locking hole 8 will be aligned with the locking column 10. Then release the rear end cap 11. After the reset spring 12 in the stretched state has no external pulling force, it will perform elastic reset, thereby driving the locking column 10 to move towards the right keyboard 2, so that the locking column 10 is inserted into the locking hole 8 of the locking block 7, and thus the positioning and locking work of the keyboard in the folded state can be completed through the effect of positioning and insertion, having the use characteristics of elastic reset and insertion locking.

[0040] Through the combined use of the above positioning and insertion structure, the utility model can effectively avoid the technical problem that the keyboard automatically unfolds due to external reasons in the folded state, has a good limiting and locking effect, is convenient for carrying and storing, reduces the space occupation area, has good practicability, and avoiding the automatic unfolding of the keyboard can also protect the keyboard itself to prevent the components from being damaged due to insufficient unfolding of the keyboard, and improves the service life of the keyboard;

[0041] Moreover, when the locking block structure of the utility model is used in the unfolded state of the keyboard, it can be horizontally stored, and it can be horizontally stored rotatably in the storage slot, specifically as shown in the attached Figure 2 and Figure 3 the state shown, thereby effectively avoiding the unilateral protrusion when the keyboard is unfolded, maintaining the horizontality of the keyboard, improving the desktop use effect of the keyboard, having good self-storage use characteristics, being convenient to use, and being suitable for popularization and use;

[0042] Finally, a suitable magnetic strip 4 is fixedly installed on the outer wall of the hinge 3 connection of the left keyboard 1 and the right keyboard 2. By setting the magnetic strip 4, left and right magnetic attraction processing can be carried out when the left keyboard 1 and the right keyboard 2 are unfolded and used, so as to have a certain magnetic connection, and also have a certain folding damping effect when folding, avoiding the situation that the left keyboard 1 and the right keyboard 2 automatically fold when picked up due to the hinge 3 being too flexible, improving the structural usability of the keyboard in the unfolded state, and having a certain magnetic damping effect.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
