[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Reference Figures 1-3This utility model provides an embodiment of a folding keyboard for a tablet computer, comprising a keyboard body 1, a sliding frame 2 slidably connected to the inner wall of the keyboard body 1, a push plate 3 slidably connected to the inner wall of the sliding frame 2, a connecting post 4 fixedly connected to the upper surface of the push plate 3, a locking block 5 fixedly connected to the top of the connecting post 4, the outer wall of the locking block 5 being disposed on the inner wall of the keyboard body 1, a spring 6 fixedly connected to the lower surface of the locking block 5, the bottom end of the spring 6 being fixedly connected to the inner wall of the sliding frame 2, a hollow frame 7 rotatably connected to the inner wall of the sliding frame 2, a support plate 8 rotatably connected to the inner wall of the hollow frame 7, a slot 9 being provided inside the sliding frame 2, the outer wall of the support plate 8 being disposed on the inner wall of the slot 9, and a folding assembly being provided on the outer wall of the keyboard body 1. Specifically, the keyboard body 1 provides sliding support for the sliding frame 2, which in turn provides sliding support for the push plate 3. When the push plate 3 is pushed, it causes the connecting post 4 to slide, which in turn causes the locking block 5 to slide. When the locking block 5 slides out of the inner wall of the keyboard body 1, the limiting and fixing between the keyboard body 1 and the sliding frame 2 is released. Then, the sliding frame 2 is pulled out from the inner wall of the keyboard body 1. The sliding frame 2 provides rotational support for the hollow frame 7, which in turn provides rotational support for the support plate 8. By rotating the hollow frame 7, it can be separated from the inner wall of the sliding frame 2. Then, by rotating the support plate 8, the support plate 8 can be moved away from the inner wall of the sliding frame 2. The support plate 8 is inserted into the inner wall of the slot 9 to support the tablet computer. By inserting the support plate 8 into the inner wall of different slots 9, the support angle of the tablet computer can be adjusted. When the stand is not needed, rotate the support plate 8 to insert it into the inner wall of the hollow frame 7, then rotate the hollow frame 7 to insert it into the inner wall of the sliding frame 2. Then push the sliding frame 2 into the inner wall of the keyboard body 1. The sliding frame 2 can limit and support the spring 6. Then, the spring 6 pushes the latch 5 into the inner wall of the keyboard body 1 to achieve the effect of hiding and fixing. By hiding the sliding frame 2, the user does not need an external stand, which saves space, makes it easier to carry, and improves portability.

[0020] Reference Figure 1 The folding assembly includes a hinge axis 10, the outer wall of which is fixedly connected to the outer wall of the keyboard body 1, and a folding plate 11 and a folding plate 2 12 are fixedly connected to the outer wall of the hinge axis 10. Specifically, the keyboard body 1 can provide fixed support for the hinge axis 10, while the hinge axis 10 can provide rotational support for the folding plate 11 and the folding plate 2 12. The hinge axis 10 can rotate the folding plate 11 and the folding plate 2 12, causing them to fold towards the keyboard body 1, thus achieving the effect of a folding keyboard.

[0021] Example 2: Reference Figure 4 The inner wall of the keyboard body 1 is slidably connected to a connecting post 2 13. A push button 14 is fixedly connected to the top of the connecting post 2 13. A locking block 2 15 is fixedly connected to the bottom of the connecting post 2 13. The outer wall of the locking block 2 15 is set on the inner wall of the sliding frame 2. A spring 2 16 is fixedly connected to the upper surface of the locking block 2 15. The top of the spring 2 16 is fixedly connected to the inner wall of the keyboard body 1. Specifically, the keyboard body 1 can provide sliding support for the connecting post 2 13, while the connecting post 2 13 can provide fixed support for the push button 1 14 and the latch 2 15. When the push button 1 14 is pulled, the push button 1 14 can drive the connecting post 2 13 to slide, and the sliding of the connecting post 2 13 will drive the latch 2 15 to slide. When the latch 2 15 slides out of the inner wall of the sliding frame 2, the limiting fixation between the keyboard body 1 and the sliding frame 2 can be released. When it is fixed again, the elastic force of the spring 2 16 pushes the latch 2 15 to slide towards the inner wall of the sliding frame 2, thus achieving the effect of fixing the limit.

[0022] Reference Figure 5 A limiting cylinder 17 is fixedly connected to the inner wall of the second folding plate 12, and a sliding column 18 is slidably connected to the inner wall of the limiting cylinder 17; a push button 19 is fixedly connected to one end of the sliding column 18, and a U-shaped block 20 is fixedly connected to the other end of the sliding column 18; a support column 21 is provided on the inner wall of the U-shaped block 20, and a retaining ring 22 is fixedly connected to the outer wall of the support column 21; the outer walls of the support column 21 and the retaining ring 22 are both provided on the inner wall of the second folding plate 12, the outer wall of the U-shaped block 20 is provided on the outer wall of the retaining ring 22, and the outer wall of the support column 21 is fixedly connected to the outer wall of the first folding plate 11; Specifically, the second folding plate 12 can provide fixed support for the limiting cylinder 17, while the limiting cylinder 17 can provide sliding support for the sliding column 18. The sliding column 18 can also provide fixed support for the second push button 19 and the U-shaped block 20. When the second push button 19 is pulled, the second push button 19 can drive the sliding column 18 to slide, and the sliding of the sliding column 18 will drive the U-shaped block 20 to slide. When the U-shaped block 20 slides out of the inner wall of the support column 21 and the retaining ring 22, the limiting of the retaining ring 22 can be released, thereby releasing the fixation between the first folding plate 11 and the second folding plate 12, so that the retaining ring 22 and the support column 21 can slide out from the inner wall of the second folding plate 12. The inner wall of the second folding plate 12 is larger than the size of the retaining ring 22, so that when the first folding plate 11 rotates, the retaining ring 22 can slide out at a certain degree of angle.

[0023] Reference Figure 5 A spring 23 is fixedly connected to the outer wall of the U-shaped block 20, and the outer wall of the spring 23 is fixedly connected to the outer wall of the limiting cylinder 17. Specifically, when folding and needing to fix folding plate 11 and folding plate 22, insert the retaining ring 22 into the inner wall of folding plate 22. Folding plate 22 can limit and support spring 3 23. The elastic force of spring 3 23 pushes U-shaped block 20 into the outer wall of support column 21 and retaining ring 22, limiting and fixing retaining ring 22, thereby fixing folding plate 11 and folding plate 22 together. By locking folding plate 11 and folding plate 22 after folding, the keyboard can be prevented from automatically unfolding due to collision or shaking in the bag or during travel, preventing key damage or accidental touch, and improving the structural stability and safety after folding.

[0024] Working principle: When the keyboard needs to be used, first pull the push button 2 19. The push button 2 19 drives the sliding column 18 to slide, and the sliding column 18 will drive the U-shaped block 20 to slide. When the U-shaped block 20 slides out of the outer wall of the support column 21 and the retaining ring 22, the lock on the folding plate 1 11 and the folding plate 2 12 can be released, allowing the keyboard to open. After using the keyboard and folding it, put the retaining ring 22 into the inner wall of the folding plate 2 12. Then, the elastic force of the spring 3 23 pushes the U-shaped block 20 to slide to the outer wall of the retaining ring 22, limiting the retaining ring 22 and locking the folding plate 1 11 and the folding plate 2 12 together. This can prevent the keyboard from automatically unfolding due to collision or shaking in the bag or during travel, prevent key damage or accidental touch, and improve the structural stability and safety after folding. Then push the push plate 3, which causes the connecting post 4 to slide. The sliding of the connecting post 4 will cause the locking block 5 to slide out of the inner wall of the keyboard body 1, thus releasing the restriction between the keyboard body 1 and the sliding frame 2, allowing the sliding frame 2 to be pulled out from the inner wall of the keyboard body 1. Then rotate the hollow frame 7 and the support plate 8, and insert the support plate 8 into the inner wall of the slot 9, so that the tablet computer can be placed on it for support. By adjusting the position of the support plate 8 in the slot 9, the support angle of the tablet computer can be adjusted. After use, slide the sliding frame 2 into the inner wall of the keyboard body 1, and the spring force of the spring 6 will push the locking block. Sliding button 15 into the inner wall of keyboard body 1 will lock keyboard body 1 and sliding frame 2, achieving a hidden and fixed effect. By hiding sliding frame 2, users do not need an external bracket, saving space, making it easier to carry and improving portability. Similarly, by pulling push button 14, connecting post 2 13 will slide, and the sliding of connecting post 2 13 will cause latch 2 15 to slide out of the inner wall of sliding frame 2, thereby releasing the limitation of sliding frame 2 and allowing the bracket to be pulled out for use. Furthermore, the elastic force of spring 2 16 pushes latch 2 15 into the inner wall of sliding frame 2, which can also lock sliding frame 2, achieving the effect of hiding the bracket.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
