[0022] Reference Figures 1-4 A foldable notebook includes a hinged first folding plate 1 and a second folding plate 2. Both the first folding plate 1 and the second folding plate 2 have interconnected placement slots, in which a foldable screen 3 is installed. The first folding plate 1 has a keyboard 6. A limit block 5 is fixedly installed on the first folding plate 1. The limit block 5 has a mounting cavity 13. A cross rod 16 is slidably installed in the mounting cavity 13. A triangular block 14 is fixedly connected to one end of the cross rod 16. A slide rod 8 is slidably connected to the limit block 5. One end of the slide rod 8 is connected to a pressing rod 12 via a first spring 10. A rotating assembly is provided on the cross rod 16. The rotating assembly includes a rotating shaft 18 rotatably installed on the cross rod 16. A locking block 17 is fixedly connected to the rotating shaft 18. The second folding plate 2 has a groove for connecting the cross rod 16. A locking groove 20 is formed on one inner wall of the groove.
[0023] A rotating plate 15 is fixedly connected to the rotating shaft 18, and a push rod 7 with an L-shaped cross section is fixedly connected to the slide rod 8. A torsion spring 19 is sleeved on the rotating shaft 18. One end of the torsion spring 19 is fixedly connected to the rotating shaft 18, and the other end of the torsion spring 19 is fixedly connected to the cross rod 16. As the push rod 7 moves together with the slide rod 8, it will move against the surface of the rotating plate 15. Under the transmission action of the rotating plate 15, the rotating shaft 18 and the cross rod 16 rotate relative to each other, and the torsion spring 19 deforms.
[0024] A second spring 9 is fitted onto the slide rod 8. One end of the second spring 9 is fixedly connected to the slide rod 8, and the other end of the second spring 9 is fixedly connected to the inner wall of the mounting cavity 13. The elastic force of the second spring 9 is greater than that of the first spring 10. A sliding groove is provided on one side of the inner wall of the mounting cavity 13. A slider is slidably connected in the sliding groove. The inner wall of one side of the mounting cavity 13 is connected to the slider through a third spring 11. The slider is fixedly connected to the cross rod 16. The sliding groove can limit the movement trajectory of the slider. One end of the third spring 11 is fixedly connected to the slider, and the other end is fixedly connected to the inner wall of the mounting cavity 13.
[0025] The first folding plate 1 is fixedly connected with two clamping blocks 4, one side surface of each clamping block 4 is fixedly connected with a rubber pad, each rubber pad is attached to the surface of the keyboard 6, the two clamping blocks 4 have a certain limiting effect on the second folding plate 2, so that the keyboard 6 is prevented from contacting the surface of the folding screen 3 when the second folding plate 2 is located directly above the first folding plate 1, and the two rubber pads are tightly attached to the two side surfaces of the keyboard 6, so that the keyboard 6 has a better clamping effect, and the keyboard 6 is effectively prevented from being separated from the first folding plate 1.
[0026] In the utility model, in use, first pull the slide rod 8, so that extrusion rod 12 not and triangle block 14 contact, after overturning second folding plate 2, second folding plate 2 and first folding plate 1 relatively rotate after, second folding plate 2 and first folding plate 1 parallelly arranged, and the surface of second folding plate 2 is attached to the upper surface of limiting block 5, then remove the external force applied on slide rod 8, under the elastic force of second spring 9, slide rod 8 relatively slide with limiting block 5, extrusion rod 12 moves to the direction close to triangle block 14 simultaneously, because the both ends of first spring 10 are fixedly connected with extrusion rod 12 and slide rod 8 respectively, and the elastic force of first spring 10 is greater than the elastic force of third spring 11, and the elastic force of second spring 9 is greater than the elastic force of first spring 10, in the process of extrusion rod 12 moving, one end of extrusion rod 12 will first move against the inclined surface of triangle block 14, triangle block 14 relatively slide with limiting block 5 simultaneously, after cross rod 16 moves, the upper end thereof will extend into the inside of recess.
[0027] When the deformation amount of third spring 11 reaches the maximum, the end surface of extrusion rod 12 is attached to the inclined surface of triangle block 14, and extrusion rod 12 cannot continue to move away from slide rod 8, when slide rod 8 continues to slide under the elastic force of second spring 9, relatively slide with extrusion rod 12 occurs, first spring 10 deforms, in the process of push rod 7 moving together with slide rod 8, move against the surface of rotating sheet 15, under the transmission of rotating sheet 15, rotating shaft 18 relatively rotates with cross rod 16, torsion spring 19 deforms, after clamping block 17 rotates, will be located in the inside of clamping groove 20, can effectively prevent second folding plate 2 from relatively rotating with first folding plate 1, at this time, keyboard 6 is clamped between two clamping blocks 4, and first folding plate 1 and second folding plate 2 are in the same plane, and the keyboard 6 on first folding plate 1 can be directly used for office, is convenient to carry, occupies smaller space, and the folding screen 3 and the keyboard 6 can be quickly taken out and used together, without additional assembly, which is beneficial to the use of the notebook computer.
[0028] In the utility model, unless another definite provision and limitation, the terms such as " install ", " connect ", " connect ", " fixed " should be broad sense understanding.
[0029] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
