Springs are fixedly installed at both ends of the bottom of the USB plug 8 and the interior of the load-bearing outer frame 7 to realize the reset of the USB plug 8. A circular hole 706 is opened in the middle of the side of the load-bearing outer frame 7. The wire 901 passes through the circular hole 706 and a line protection component is provided between the wire 901 and the circular hole 706. The line protection component includes an elastic pull rope 9. The elastic pull rope 9 is hollow and its two ends are fixedly connected to the interior of the load-bearing outer frame 7 and the lower plate 2, respectively. The wire 901 is spiral and slides inside the elastic pull rope 9. A limit ring 10 is provided inside the circular hole 706.Both sides of the limiting ring 10 are fixedly mounted with rotating shafts 1002, and are rotatably installed inside the circular hole 706 through the cooperation of the rotating shafts 1002. Several spherical bodies 1001 are rotatably installed on the inner side of one end of the limiting ring 10. The inner diameter of the limiting ring 10 is larger than the diameter of the elastic pull rope 9, and the outer diameter of the limiting ring 10 is smaller than the diameter of the circular hole 706.

[0030] In this embodiment of the invention, the protective component includes a rubber buffer sheet 401. There are several rubber buffer sheets 401, which are respectively fixedly installed around the bottom of the keyboard assembly 4. A rectangular groove 202 is provided inside the lower plate 2. The keyboard assembly 4 is fixedly installed inside the rectangular groove 202 by several rubber buffer sheets 401. The installation position of the keyboard assembly 4 is flush with the top surface of the lower plate 2. Protective cotton pads 203 are fixedly installed around the top surface of the lower plate 2. The installation height of the protective cotton pads 203 exceeds that of the keyboard assembly 4. A counterweight plate 201 is fixedly installed at the bottom of the lower plate 2. A first magnetic suction plate 302 is fixedly installed at the end of the lower plate 2 and the end of the upper plate 3.

[0031] This invention also discloses a tablet computer, including a computer body 1, a plug-in interface 101 on the side of the computer body 1, a keyboard connection protection structure for the tablet computer, a protection component and a line plug-in component adapted to the computer body 1, a keyboard socket on one side of the computer body 1, the keyboard socket and the plug-in interface 101 being located at the middle of the two sides of the computer body 1 respectively, the size of the computer body 1 being adapted to the size of the lower plate 2 and the upper plate 3, and the location of the keyboard socket on the side of the computer body 1 being adapted to the installation location of the protection component and the line plug-in component.

[0032] In use, thanks to the protective components and the wiring connector components, during assembly, firstly, the upper plate 3 is flipped over, allowing it to rotate along the arc-shaped frame 5 via the elastic band 501 until the arc-shaped frame 5 retracts into the arc-shaped storage slot 301. Simultaneously, the two first magnetic plates 302 fixedly installed on the sides of the upper plate 3 and the lower plate 2 adhere to each other. Then, the keyboard connector of the computer body 1 is inserted downwards until the load-bearing outer frame 7 is inserted into the keyboard connector. Electrical connection is then achieved through the internal USB connector 8.

[0033] Furthermore, when the device is finished using and is placed away, the upper shelf 3 and the computer body 1 can be directly held and rotated along the arc-shaped frame 5 until the computer body 1 and the lower shelf 2 are in contact, thus completing the storage. Simultaneously, the rotation of the computer body 1 causes the load-bearing outer frame 7 inserted inside the keyboard port to move. The load-bearing outer frame 7 can slide within the arc-shaped groove 6 through the cooperation of the arc-shaped slider 703 and the arc-shaped limiting groove 601. At the same time, as the load-bearing outer frame 7 rotates, the elastic pull cord 9 pulls the USB plug 8, causing the USB plug 8 to slide within the load-bearing outer frame 7 through the cooperation of the sliding rods 801 on both sides and the corresponding arc-shaped grooves 705, disconnecting it from the computer body 1. When the load-bearing outer frame 7 rotates and the elastic pull cord 9 is pulled, the elastic pull cord 9 is subjected to force and contacts the limiting ring 10 and the spherical body 1001 rotated at its end. Simultaneously, the limiting ring 10 is deflected in direction through the rotating shaft 1002, effectively reducing the force on the elastic pull cord 9. The force ensures the pulling effect while improving the protection of the elastic pull rope 9 and the internal wire 901. When in use, by flipping the upper plate 3 and the computer body 1, it rotates along the arc frame 5 via the elastic band 501 until the arc frame 5 retracts into the arc storage groove 301. At the same time, the two first magnetic plates 302 fixedly installed on the side of the upper plate 3 and the side of the lower plate 2 fit together. During the rotation of the computer body 1, the load-bearing outer frame 7 can rotate and reset along the direction of the arc slide 6 driven by the computer body 1, so that the USB plug 8 is reset and re-inserted into the keyboard socket. Thus, by realizing that the USB plug 8 can be automatically inserted and unplugged as the upper plate 3 is closed and opened, the keyboard socket of the computer body 1 and the USB plug 8 are protected. This can effectively prevent power loss. When the device is not in use, the USB plug 8 is automatically unplugged, which can prevent damage to the inside of the keyboard socket due to collision or drop, thus improving the protection effect and ease of use of the device.

[0034] In this embodiment of the invention, by setting up the protective components, when the upper plate 3 is flipped over to the computer body 1 after assembly, the display screen of the computer body 1 can first come into contact with the protective cotton pad 203, avoiding scratches on the screen. At the same time, when the device slips or is subjected to pressure, the keyboard assembly 4 can squeeze the corresponding rubber buffer 401 under force, effectively reducing the damage to the screen and improving the protective effect of the computer body 1.

The USB plug 8 is slidably installed inside the load-bearing outer frame 7 through the cooperation of the slide rods 801 and the arc-shaped grooves 705. Inside the load-bearing outer frame 7, a wire 901 is provided between the middle of the side of the USB plug 8 and the keyboard assembly 4, and is electrically connected through the wire 901. Springs are fixedly installed at both ends of the bottom of the USB plug 8 and the interior of the load-bearing outer frame 7 to achieve the reset of the USB plug 8. A circular hole 706 is opened in the middle of the side of the load-bearing outer frame 7. The wire 901 passes through the circular hole 706, and a line protection component is provided between the wire 901 and the circular hole 706.

The inner diameter of the limiting ring 10 is larger than the diameter of the elastic pull rope 9, and the outer diameter of the limiting ring 10 is smaller than the diameter of the circular hole 706.

[0037] This invention also discloses a tablet computer, including a computer body 1, a plug-in interface 101 on the side of the computer body 1, a keyboard connection protection structure for the tablet computer, a protection component and a line plug-in component adapted to the computer body 1, a keyboard socket on one side of the computer body 1, the keyboard socket and the plug-in interface 101 being located at the middle of the two sides of the computer body 1 respectively, the size of the computer body 1 being adapted to the size of the lower plate 2 and the upper plate 3, and the location of the keyboard socket on the side of the computer body 1 being adapted to the installation location of the protection component and the line plug-in component.

[0038] In use, thanks to the protective components and the wiring connector components, during assembly, firstly, the upper plate 3 is flipped over, allowing it to rotate along the arc-shaped frame 5 via the elastic band 501 until the arc-shaped frame 5 retracts into the arc-shaped storage slot 301. Simultaneously, the two first magnetic plates 302 fixedly installed on the sides of the upper plate 3 and the lower plate 2 adhere to each other. Then, the keyboard connector of the computer body 1 is inserted downwards until the load-bearing outer frame 7 is inserted into the keyboard connector. Electrical connection is then achieved through the internal USB connector 8.

[0039] Furthermore, when the device is finished using and is placed away, the upper shelf 3 and the computer body 1 can be directly held and rotated along the arc-shaped frame 5 until the computer body 1 and the lower shelf 2 are in contact, thus completing the storage. Simultaneously, the rotation of the computer body 1 causes the load-bearing outer frame 7 inserted inside the keyboard port to move. The load-bearing outer frame 7 can slide within the arc-shaped groove 6 through the cooperation of the arc-shaped slider 703 and the arc-shaped limiting groove 601. At the same time, as the load-bearing outer frame 7 rotates, the elastic pull cord 9 pulls the USB plug 8, causing the USB plug 8 to slide within the load-bearing outer frame 7 through the cooperation of the sliding rods 801 on both sides and the corresponding arc-shaped grooves 705, disconnecting it from the computer body 1. When the load-bearing outer frame 7 rotates and the elastic pull cord 9 is pulled, the elastic pull cord 9 is subjected to force and contacts the limiting ring 10 and the spherical body 1001 rotated at its end. Simultaneously, the limiting ring 10 is deflected in direction through the rotating shaft 1002, effectively reducing the force on the elastic pull cord 9. The force ensures the pulling effect while improving the protection of the elastic pull rope 9 and the internal wire 901. When in use, by flipping the upper plate 3 and the computer body 1, it rotates along the arc frame 5 via the elastic band 501 until the arc frame 5 retracts into the arc storage groove 301. At the same time, the two first magnetic plates 302 fixedly installed on the side of the upper plate 3 and the side of the lower plate 2 fit together. During the rotation of the computer body 1, the load-bearing outer frame 7 can rotate and reset along the direction of the arc slide groove 6 driven by the computer body 1, so that the USB plug 8 is reset and re-inserted into the keyboard socket. Thus, by realizing that the USB plug 8 can be automatically inserted and unplugged as the upper plate 3 is closed and opened, the keyboard socket of the computer body 1 and the USB plug 8 are protected. This can effectively prevent power loss. When the device is not in use, the USB plug 8 is automatically unplugged, which can prevent damage to the inside of the keyboard socket due to collision or drop, thus improving the protection effect and ease of use of the device.
