[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This portable and multifunctional tablet case features a modular design with three shells, allowing for flexible switching between different tablet usage scenarios. The support frame and retaining strap work together to quickly create an isosceles triangle support, enabling users to adjust the tablet to a comfortable viewing angle. Further separation of the third and second shells reveals a hidden storage compartment for temporarily storing small items such as tickets and keys, reducing the need for an extra storage bag. Additionally, four parallel card holders at the bottom of the support frame allow for the categorized storage of bank cards, transportation cards, and other cards, enhancing the convenience of using the first shell.
[0013] 2. This portable and multifunctional flat cover, through the design of the third shell, allows the airbag to absorb the impact force on the third shell first when the flat cover is dropped. When the airbag deforms, the gas in the inner cavity pushes the ball to open the air tube, realizing its degassing and buffering. At the same time, during the deformation process, the airbag also squeezes the partition, causing the spring to compress. The airbag further disperses the impact force by utilizing the elastic deformation of the spring and the sliding of the partition, thereby effectively reducing the risk of damage to the flat cover due to collision.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1 - Figure 7A portable multi-functional tablet case includes a first case 1. The outer wall of the first case 1 is provided with a folding cloth bag 2, a support frame 4, and a fixing strap 7. The inner cavity of the folding cloth bag 2 has a slot 3. The inner wall of the support frame 4 is inlaid with a magnetic plate 5. The bottom of the support frame 4 is provided with a card slot 6. The bottom of the fixing strap 7 is inlaid with a first magnetic chuck 8. The top of the first case 1 is inlaid with a second magnetic chuck 9. The outer wall of the first case 1 is provided with a second case 10. The outer wall of the first case 1 away from the second case 10 is provided with a third case 13. The top of the second case 10 is inlaid with a third magnetic chuck 11 and a fourth magnetic chuck 12. The top of the second case 10 is provided with a storage slot 16. The inner cavity of the third case 13 is provided with a buffer assembly 14. The top of the third case 13 is inlaid with a fifth magnetic chuck 15. The bottom of the support frame 4 is provided with a card holder 17.
[0018] In the above structure, by setting the first shell 1, the second shell 10 and the third shell 13, when the first shell 1 is in use, the third shell 13 is folded and separated from the first shell 1, and the third shell 13 is folded and separated from the second shell 10 to expose the storage slot 16. Then the third shell 13 is folded to the bottom of the second shell 10, thereby completing the extended use of the first shell 1.
[0019] In a preferred embodiment: the cushioning assembly 14 includes an airbag cushion 141, the outer wall of the airbag cushion 141 is provided with an air tube 145, the inner wall of the air tube 145 is respectively fixedly installed with an arc-shaped sleeve 146 and a cross base 149, the top of the airbag cushion 141 is provided with a partition 142, the top of the partition 142 is provided with a spring 143, the outer wall of the third shell 13 is provided with a cover plate 144, and the inner cavity of the air tube 145 is respectively provided with a ball 147 and a spring 148. In a preferred embodiment: the air tube 145 is connected to the air outlet of the airbag cushion 141, the sphere 147 is located on the inner wall of the arc sleeve 146 and its diameter is larger than the opening diameter of the arc sleeve 146, the second spring 148 is located at the bottom of the sphere 147 and one end overlaps with the sphere 147 and the other end overlaps with the cross base 149, the outer wall of the partition 142 is slidably fitted to the inner wall of the third shell 13, one end of the first spring 143 overlaps with the top of the partition 142 and the other end overlaps with the bottom of the cover plate 144; In the above structure, by configuring the airbag cushion 141 and spring 143, when the third shell 13 is folded and combined with the first shell 1, if the first shell 1 falls, the third shell 13 will preferentially contact the ground. When the third shell 13 contacts the ground, the airbag cushion 141 will share the force of the third shell 13, causing the airbag cushion 141 to deform. This compresses the gas inside the airbag cushion 141, causing the compressed gas to pass through the air tube 145. The gas then contacts the sphere 147 located inside the air tube 145, pushing the sphere 147 to compress the spring 148. This causes the sphere 147 to detach from the inner wall of the arc-shaped sleeve 146, allowing... It opens the trachea 145 to expel the gas, thus completing the first stage of buffering. At the same time, after the gas is expelled, the sphere 147 is reset to the inner wall of the arc-shaped sleeve 146 by the rebound of the second spring 148, thereby sealing the inner cavity of the trachea 145 and isolating the gas in the inner cavity of the airbag pad 141, thus completing its sealing. Meanwhile, when the airbag pad 141 is subjected to force, the volume of the deformed airbag pad 141 will push the partition 142 to slide along the inner wall of the third shell 13, so that the force of the airbag pad 141 will be evenly distributed in the partition 142. The sliding partition 142 will drive the first spring 143 to compress, thus achieving the second stage of buffering. The partition 142 can be reset by the rebound of the first spring 143.
[0020] In a preferred embodiment: the support frame 4 and the fixing strap 7 overlap at a 45-degree angle, and the unmounted side of the first magnetic chuck 8 is the S pole, which is magnetically attracted to the unmounted N pole of the magnetic chuck plate 5. In the above structure, by setting the support frame 4 and the fixing strap 7, when the first shell 1 is in use, one end of the support frame 4 is folded and separated from the outer wall of the first shell 1, so that the included angle of rotation is 45 degrees. Then, the fixing strap 7 is wrapped around one end of the support frame 4, so that the fixing strap 7, the support frame 4 and the first shell 1 form a triangle. Then, the fixing strap 7 is attached to the non-embedded side of the first magnetic chuck 8 and the non-embedded side of the magnetic plate 5, so that the first magnetic chuck 8 and the magnetic plate 5 will generate magnetic attraction, thus fixing the fixing strap 7, the support frame 4 and the first shell 1 into a triangle, thereby realizing the use support of the first shell 1. When not in use, the support frame 4 and the fixing strap 7 can be stored in the outer wall of the first shell 1 by the reverse operation, thus making it more portable.
[0021] In a preferred embodiment: the rotation angle between the second housing 10 and the first housing 1 is 90 degrees, the side of the fourth magnetic chuck 12 that is not embedded is the S pole, and it is magnetically attracted to the N pole of the side of the second magnetic chuck 9 that is not embedded. In the above structure, by setting the second shell 10 and the first shell 1, when the first shell 1 needs to be extended for use, the second shell 10 is folded and separated from the first shell 1, so that the side of the fourth magnetic chuck 12 that is not embedded will be separated from the side of the second magnetic chuck 9 that is not embedded, so that the second shell 10 and the first shell 1 are folded at a 90-degree angle for use. At the same time, by performing the opposite operation, the second shell 10 and the first shell 1 can be folded and fixed for storage by magnetic attraction between the side of the fourth magnetic chuck 12 and the side of the second magnetic chuck 9 that is not embedded.
[0022] In a preferred embodiment: the rotation angle between the third housing 13 and the second housing 10 is 180 degrees, the fifth magnetic chuck 15 and the unmounted side are N poles, and it is magnetically attracted to the unmounted side S pole of the third magnetic chuck 11. The rotation angle between the third housing 13 and the third magnetic chuck 11 is 90 degrees, and the unmounted side of the fifth magnetic chuck 15 is correspondingly set to the mounted side of the second magnetic chuck 9. In the above structure, by setting the third shell 13 and the second shell 10, and by folding and separating the third shell 13 from the first shell 1, the fifth magnetic chuck 15 embedded in the top of the third shell 13 will detach from the second magnetic chuck 9. The detached third shell 13 will then cause the second shell 10 to separate in the same way, resulting in a 90-degree folding angle between the first shell 1 and the second shell 10. Then, the third shell 13 is separated from the second shell 10, and the fifth magnetic chuck 15 is not embedded in the second shell 9. The surface will separate from the unmounted side of the third magnetic chuck 11, and then the third shell 13 will be folded so that the folding angle between the third shell 13 and the second shell 10 is 360 degrees, so that the third shell 13 will be folded to the bottom of the second shell 10, thereby revealing the storage groove 16 provided in the inner cavity of the second shell 10. At the same time, when the third shell 13 is folded to the bottom of the second shell 10, the third shell 13 and the fixing strap 7 can be stored in the outer wall of the first shell 1 by performing the opposite operation.
[0023] In a preferred embodiment: there are four card holders 17, and the four card holders 17 are respectively arranged in parallel at the bottom of the support frame 4; In the above structure, by setting the card holder 17, when the first shell 1 is in use, its cards and other items can be placed in the four parallel inner cavities of the card holder 17 for storage, making it convenient to take them out for use later.
[0024] Working principle: First, when the first shell 1 is in use, the support frame 4 is folded and separated from the outer wall of the first shell 1, rotated to an angle of 40 degrees with the first shell 1, and then the fixing strap 7 is pulled around the bottom of the support frame 4. This causes the side of the first magnetic chuck 8 that is not embedded to magnetically attract the side of the magnetic plate 5 that is not embedded, thereby forming an isosceles triangle support with the fixing strap 7, the support frame 4 and the first shell 1. Then, external force is applied to separate the third shell 13 from the first shell 1, causing the fifth magnetic chuck 15 to separate from the second magnetic chuck 9. The third shell 13 is then folded away from the outer wall of the first shell 1. At this time, the second shell 10 separates synchronously with the third shell 13, so that the folding angle between the first shell 1 and the second shell 10 is 90 degrees. Then, the third shell 13 is further separated from the second shell 10, so that the unattached side of the fifth magnetic chuck 15 will magnetically separate from the unattached side of the third magnetic chuck 11, causing the third shell 13 to rotate around the second shell 10 by 360 degrees. Fold it ten degrees to the bottom of the second shell 10. At this time, the storage groove 16 inside the second shell 10 is fully exposed, thus completing the use and extended use of the first shell 1. At the same time, when storage is needed, the third shell 13 is folded back from the bottom of the second shell 10, so that the un-embedded side of the fifth magnetic chuck 15 will re-attach to the embedded side of the second magnetic chuck 9. Then, the third shell 13 is folded back to the outer wall of the first shell 1, so that the second shell 10 will fit against the outer wall of the first shell 1 along with the third shell 13, thus realizing its storage. Secondly, when the first shell 1 lands, the airbag 141 inside the third shell 13 distributes the impact, causing the airbag 141 to deform under the impact force. This compresses the gas inside the airbag 141, which then passes through the air pipe 145, the arc-shaped sleeve 146, and pushes the ball 147, causing the spring 148 to compress and move. This causes the ball 147 to detach from the inner wall of the arc-shaped sleeve 146, opening the air pipe 145 and allowing the gas to escape through the cross base 149. Simultaneously, the airbag 141 deforms... The change will push the partition 142 to slide upward along the inner wall of the third shell 13, causing it to drive the spring 143 to compress, thereby evenly dispersing the force on the airbag cushion 141 during the sliding process of the partition 142, thus completing the unloading of the force when the third shell 13 falls. Then, after the impact force disappears, the spring 143 rebounds, pushing the partition 142 to reset, causing the airbag cushion 141 to recover. At the same time, the spring 2 148 rebounds, pushing the ball 147 to re-block the opening of the arc sleeve 146, sealing the air tube 145, and restoring the inner cavity of the airbag cushion 141 to a sealed state.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
