[0033] Please refer to Figure 1-8 , the present invention provides the following technical solution: A three-proof tablet computer with a safety backup power supply, including a backup power supply body 1. The backup power supply body 1 is of an existing structure and will not be elaborated here. A protective frame 2 is fixedly connected to the top of the backup power supply body 1. The cross-section of the protective frame 2 is in a U shape. A tablet computer is arranged inside the protective frame 2. The tablet computer is of an existing structure and will not be elaborated here. The tablet computer is connected to the backup power supply body 1 through a circuit. A communication groove is opened inside the protective frame 2. The tablet computer can be protected by the protective frame 2. Two symmetric extension parts 3 are fixedly connected to one side of the backup power supply body 1. A rotating plate 5 is rotatably connected inside the protective frame 2. A protective plate 4 is arranged on the top of the protective frame 2. The screen of the tablet computer can be protected by the protective plate 4. A rotating groove 38 is opened on one side of the protective plate 4. The surface of the rotating plate 5 is rotatably connected to the inside of the rotating groove 38. The protective plate 4 can rotate through the rotating plate 5. A transmission groove 29 is opened inside the protective frame 2. A transmission frame 30 and a transmission plate 31 are slidably connected to the inside of the transmission groove 29. A protective fixing device is arranged inside the transmission groove 29. A hidden groove 6 is opened on the top of the protective plate 4. The cross-section of the hidden groove 6 is in an inverted U shape. The hidden groove 6 is composed of two longitudinal grooves and a transverse groove. Support rods 7 are arranged inside both longitudinal grooves of the hidden groove 6. A rotating shaft 10 and a connecting shaft 8 are fixedly connected between the two support rods 7. The connecting shaft 8 is arranged inside the transverse groove of the hidden groove 6. A moving groove 11 communicating with the inside of the hidden groove 6 is opened inside the protective plate 4. The rotating shaft 10 is arranged inside the moving groove 11. After the user rotates the connecting shaft 8 inside the hidden groove 6, the user can lift the device through the connecting shaft 8, making the carrying method of the device more diverse and improving the portability of the device to a certain extent. Positioning grooves 12 are opened on the upper and lower surfaces inside the moving groove 11. The rotating shaft 10 is slidably connected to the inside of the positioning groove 12. The rotating shaft 10 can slide into and out of the inside of the positioning groove 12. An angle support device is arranged at the bottom of the backup power supply body 1.

[0034] Two symmetrical first sliding grooves 13 are formed inside the protection plate 4. The inside of the first sliding groove 13 is communicated with the inside of the hidden groove 6. A first pressing block 14 is slidably connected inside the first sliding groove 13. Two symmetrical convex blocks 40 are fixedly connected to one side of the first pressing block 14 close to the connecting shaft 8. The convex blocks 40 are made of rubber. Two symmetrical grooves 9 are formed on the outer surface of the connecting shaft 8. A first spring 15 is fixedly connected to the side of the first pressing block 14 away from the convex block 40. One end of the first spring 15 away from the first pressing block 14 is fixedly connected to the inner wall of the first sliding groove 13. The first spring 15 can be compressed and reset by the movement of the first pressing block 14. During the process of the user sliding the connecting shaft 8 into the hidden groove 6, the first pressing block 14 is pushed to move by the convex block 40, so that the first spring 15 is compressed. After the connecting shaft 8 slides into the hidden groove 6, the first spring 15 resets to make the first pressing block 14 slide into the groove 9 through the convex block 40 and press against the inner surface of the groove 9, thereby positioning and fixing the positions of the connecting shaft 8 and the support rod 7, enabling the support rod 7 and the connecting shaft 8 to be hidden inside the hidden groove 6, making the outer surface of the protection plate 4 cleaner, and enabling the user to use the device more conveniently.

[0035] A power groove 39 communicated with the inside of the hidden groove 6 is formed inside the protection plate 4, which enables the user to take out the connecting shaft 8 more smoothly through the power groove 39.

[0036] Cross grooves 16 are formed on both the left and right sides of the protection frame 2. The cross section of the cross groove 16 is cross-shaped. A limiting plate 19 is slidably connected inside the cross groove 16. A baffle 17 is rotatably connected to the top of the limiting plate 19. The surface of the baffle 17 is slidably connected to the inside of the cross groove 16. Sliders 18 are fixedly connected to both sides of the baffle 17. The surface of the slider 18 is slidably connected to the inside of the cross groove 16. A second spring 20 is fixedly connected to the bottom of the limiting plate 19. The bottom end of the second spring 20 is fixedly connected to the top of the backup power supply body 1. The second spring 20 can be compressed and reset by the movement of the baffle 17.

[0037] When the protection plate 4 is close to the top of the protection frame 2, the protection plate 4 squeezes the baffle 17, causing the baffle 17 and the slider 18 to slide into the inside of the cross groove 16, positioning and fixing the position of the baffle 17, enabling the baffle 17 to protect the jack of the tablet computer, reducing to a certain extent the situation that dust and other impurities in the external environment easily enter the inside of the jack of the tablet computer, resulting in faults such as blockage of the jack of the tablet computer, and enabling the tablet computer to be used and stored more smoothly. At the same time, when the tablet computer is in use, the extrusion of the protection plate 4 on the baffle 17 is released, causing the cross groove 16 and the baffle 17 to move upward under the action of the second spring 20, and the slider 18 slides out of the inside of the cross groove 16. At the same time, the baffle 17 can rotate on the top of the limiting plate 19, changing the baffle 17 from a vertical state to a horizontal state, enabling the user to use the socket of the tablet computer more smoothly, and enabling the tablet computer to be better protected when not in use.

[0038] The protection and fixing device includes a gear 32. The surface of the gear 32 is rotatably connected to the inside of the transmission groove 29. Two fixing frames 36 extending to the outside of the protection frame 2 are slidably connected to the inside of the transmission groove 29. The cross section of the fixing frame 36 is L-shaped. The top of the fixing frame 36 is provided with an inclined surface. Two symmetric fixing grooves 37 are opened at the bottom of the protection plate 4. The surface of the fixing frame 36 is slidably connected to the inside of the fixing groove 37. The transmission plate 31 and the transmission frame 30 are respectively fixedly connected to the bottoms of the two fixing frames 36. The gear 32 is arranged between the transmission frame 30 and the transmission plate 31. Tooth teeth are provided on one side of the transmission frame 30 and the transmission plate 31 close to the gear 32. The transmission frame 30 and the transmission plate 31 are meshed with the surface of the gear 32 through the tooth teeth. One side of the gear 32 is fixedly connected to a rotating column 33 that rotates and extends to the outside of the protection frame 2.

[0039] A limiting rod 35 is fixedly connected to the inside of the transmission groove 29. The surface of the limiting rod 35 is slidably connected to the inside of the fixing frame 36. One side of the fixing frame 36 is fixedly connected to a fourth spring 34 movably sleeved on the limiting rod 35. The end of the fourth spring 34 away from the fixing frame 36 is fixedly connected to the inner wall of the transmission groove 29. The compression and reset of the fourth spring 34 can be achieved through the movement of the fixing frame 36.

[0040] When the user closes the protection plate 4 and the protection plate 4 moves in the direction close to the protection frame 2, the protection plate 4 can push the two fixing frames 36 to move relatively away from each other through the inclined surfaces at the top of the fixing groove 37 and the fixing frame 36, compressing the fourth spring 34. When the fixing frame 36 slides into the vertical groove of the fixing groove 37, the fourth spring 34 resets to make the fixing frame 36 slide into the horizontal groove of the fixing groove 37, and the position of the protection plate 4 is fixed by the fixing frame 36, enabling the protection plate 4 to more smoothly protect the display screen of the tablet computer. At the same time, when the user rotates the rotating column 33, the gear 32 drives the transmission frame 30 and the transmission plate 31 to move relatively, and the two fixing frames 36 can slide into the vertical groove of the fixing groove 37, and the fixing of the protection plate 4 is released, making the fixing and release of the position of the protection plate 4 more convenient and enabling the user to use the device more conveniently.

[0041] The angle support device includes a bottom plate 21, the top of the bottom plate 21 is fixedly connected to the bottom of the backup power supply body 1, a positioning groove 24 is opened at the bottom of the bottom plate 21, the connecting shaft 8 can slide into the positioning groove 24, a second sliding groove 25 is opened inside the bottom plate 21, a second pressing block 27 is slidably connected inside the second sliding groove 25, an arc groove is opened on one side of the second pressing block 27 close to the groove 9, a sloping surface is arranged at the bottom of the second pressing block 27, a third spring 26 is fixedly connected to the side of the second pressing block 27 away from the groove 9, and one end of the third spring 26 away from the second pressing block 27 is fixedly connected to the inner wall of the second sliding groove 25. The third spring 26 can be compressed and reset by the movement of the second pressing block 27.

[0042] When it is necessary to support the device with the support rod 7 and the connecting shaft 8, after the user flips the protection plate 4 to the bottom of the backup power supply body 1 and makes the connecting shaft 8 slide into the positioning groove 24, the inner surface of the groove 9 can push the second pressing block 27 to move through the sloping surface arranged at the bottom of the second pressing block 27, compressing the third spring 26. When the connecting shaft 8 moves to a suitable position, the second pressing block 27 presses against the inner surface of the groove 9 under the action of the third spring 26, positioning the positions of the groove 9 and the connecting shaft 8. At the same time, when the user slides the rotating shaft 10 into the positioning grooves 12 at different positions on the lower surface of the moving groove 11, the inclination angle of the support rod 7 can be adjusted, enabling the device to support the tablet computer at different angles, so that the protection plate 4 can support the tablet computer while protecting it, making it more convenient for the user to use the device.

[0043] A heat dissipation groove 22 is formed in the top of the bottom plate 21. A heat dissipation fin 23 is arranged inside the heat dissipation groove 22. The material of the heat dissipation fin 23 is a material with fast heat conduction such as aluminum. Through the heat dissipation fin 23, the heat generated by the backup power supply body 1 can be guided. A heat dissipation hole 28 is formed inside the bottom plate 21. Through the mutual cooperation of the heat dissipation hole 28 and the heat dissipation fin 23, the heat of the backup power supply body 1 can be dissipated more smoothly.

[0044] Working principle: For a three-proof tablet computer with a safety backup power supply, when in use, the screen of the tablet computer can be protected by the protection plate 4. After the user rotates the connecting shaft 8 into the hidden groove 6, the user can lift the device through the connecting shaft 8, making the carrying method of the device more diverse and improving the portability of the device to a certain extent. During the process of the user sliding the connecting shaft 8 into the hidden groove 6, the first pressing block 14 is pushed to move by the convex block 40, compressing the first spring 15. After the connecting shaft 8 slides into the hidden groove 6, the first spring 15 resets, causing the first pressing block 14 to slide into the groove 9 through the convex block 40 and pressing against the inner surface of the groove 9, thereby positioning and fixing the positions of the connecting shaft 8 and the support rod 7, enabling the support rod 7 and the connecting shaft 8 to be hidden inside the hidden groove 6, making the outer surface of the protection plate 4 cleaner and enabling the user to use the device more conveniently.

[0045] When the protection plate 4 is closely attached to the top of the protection frame 2, the protection plate 4 squeezes the baffle 17, causing the baffle 17 and the slider 18 to slide into the cross slot 16, positioning and fixing the position of the baffle 17, and enabling the baffle 17 to protect the jack of the tablet computer. To a certain extent, it reduces the situation that dust and other impurities in the external environment easily enter the jack of the tablet computer, preventing faults such as blockage of the jack of the tablet computer, and enabling the tablet computer to be used and stored more smoothly. At the same time, when the tablet computer is in use, the extrusion of the protection plate 4 on the baffle 17 is released, causing the cross slot 16 and the baffle 17 to move upward under the action of the second spring 20, and the slider 18 slides out of the cross slot 16. At the same time, the baffle 17 can rotate on the top of the limiting plate 19, changing the baffle 17 from a vertical state to a horizontal state, enabling the user to use the socket of the tablet computer more smoothly.

[0046] When the user closes the protection plate 4, when the protection plate 4 moves in the direction close to the protection frame 2, the protection plate 4 can push the two fixing frames 36 to move relatively away from each other through the fixing groove 37 and the inclined surface at the top of the fixing frame 36, so that the fourth spring 34 is compressed. When the fixing frame 36 slides into the vertical groove of the fixing groove 37, the fourth spring 34 resets to make the fixing frame 36 slide into the transverse groove of the fixing groove 37, and the position of the protection plate 4 is fixed by the fixing frame 36, so that the protection plate 4 can more smoothly protect the display screen of the tablet computer. At the same time, by the user rotating the rotating column 33, the gear 32 drives the transmission frame 30 and the transmission plate 31 to move relatively, and the two fixing frames 36 can slide into the vertical groove of the fixing groove 37, and the fixing of the protection plate 4 is released, making the position fixing and fixing release of the protection plate 4 more convenient;

[0047] When the support rod 7 and the connecting shaft 8 are needed to support the device, after the user flips the protection plate 4 to the bottom of the backup power supply body 1 and makes the connecting shaft 8 slide into the positioning groove 24, through the inclined surface provided at the bottom of the second tightening block 27, the inner surface of the groove 9 can push the second tightening block 27 to move, so that the third spring 26 is compressed. When the connecting shaft 8 moves to a suitable position, the second tightening block 27 tightens the inner surface of the groove 9 under the action of the third spring 26, so that the positions of the groove 9 and the connecting shaft 8 are positioned. At the same time, by the user sliding the rotating shaft 10 into the positioning grooves 12 at different positions on the lower surface of the moving groove 11, the inclination angle of the support rod 7 can be adjusted, and the device can support the tablet computer at different angles, so that the protection plate 4 can support the tablet computer while protecting it, making it more convenient for the user to use the device. The heat generated by the backup power supply body 1 can be dissipated through the heat dissipation fins 23. The heat dissipation holes 28 are opened inside the bottom plate 21. Through the mutual cooperation of the heat dissipation holes 28 and the heat dissipation fins 23, the heat of the backup power supply body 1 can be dissipated more smoothly.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
