Description

Technical Field

[0001] This utility model relates to the field of tablet computer technology, specifically a tablet computer with a protective structure. Background Technology

[0002] With the widespread use of mobile smart devices, tablet computers have become an important tool for people's work, study and entertainment due to their portability and multifunctionality. In daily use, tablet computers often face the problem of limited placement angles, making it difficult to meet the viewing and operation needs of different scenarios. At the same time, the lack of effective protective measures during carrying can easily lead to damage to tablet computers due to collisions and squeezing, affecting the lifespan of the device and the user experience. Therefore, designing a tablet computer with a flexible support structure and efficient protection functions can effectively solve the above problems and improve the convenience of use and the safety of the device.

[0003] However, traditional tablet computer support and protection structures have shortcomings. On the one hand, traditional support structures usually adopt simple stand or fixed angle design, which cannot achieve flexible adjustment at multiple angles and cannot meet the user's needs in different scenarios. On the other hand, traditional protective cases are mostly simple wrapping, lacking storage and fixing design for support components, which makes the support structure easy to shake and collide during carrying. This not only affects the convenience of carrying, but may also cause secondary damage to the tablet computer due to the loosening of support components, and cannot provide comprehensive and reliable protection for the device. Therefore, we propose a tablet computer with a protective structure. Utility Model Content

[0039] Positioning ring 9: A circular structure in the middle of the back of the protective sleeve 2, with positioning block 10 on it cooperating with positioning hole 17 of support ring 16 to realize the storage and fixation of support strip 8;

[0040] Positioning block 10: The structure on the end face of the positioning ring 9, with a compression spring 11 inside, which fixes and stores the support bar 8 through the through positioning hole 17;

[0041] Compression spring 11: Located inside the positioning block 10, it provides a forward pushing force to the positioning block 10, so that it cooperates with the positioning hole 17 to fix the support bar 8;

[0042] Connector 12: The front end structure of the rotating ring 4 is inserted into and rotated with the connecting groove 18 of the fixed cylinder 3 to ensure that the rotating ring 4 can rotate flexibly inside the fixed cylinder 3;

[0043] Movable cavity 13: A cavity on the outer cylindrical surface of the rotating ring 4, used to accommodate the friction end 5 and the fixing spring 6, providing space for the positioning function;

[0044] Slider 14: Located on both sides of the end of the telescopic bar 7, it cooperates with the slide groove 15 of the support bar 8 to realize the sliding telescopic function of the telescopic bar 7 and the support bar 8;

[0047] Positioning hole 17: The hole structure inside the support ring 16, which cooperates with the positioning block 10 to fix and store the support strip 8 on the back of the protective sleeve 2;

[0048] Connecting groove 18: The groove in the center of the fixed cylinder 3, which cooperates with the connector 12 of the rotating ring 4 to realize the installation and rotation of the rotating ring 4;

[0049] Friction groove 19: A semi-circular groove on the inner wall of the fixed cylinder 3, which cooperates with the friction end 5 and achieves the positioning of the rotating ring 4 under the action of the fixed spring 6.

[0050] Working principle: First, the rotating ring 4 functions within the fixed cylinder 3. Since the connector 12 at the front end of the rotating ring 4 is inserted into the connecting groove 18 at the center of the fixed cylinder 3 and rotates in engagement, the user can manually rotate the rotating ring 4. During rotation, the friction end 5 within the movable cavity 13 of the outer cylindrical surface of the rotating ring 4 forms a frictional engagement with the friction groove 19 on the cylindrical surface of the inner wall of the fixed cylinder 3. Under the action of the fixed spring 6, the friction end 5 is tightly pressed against the friction groove 19, ensuring not only the stability of the rotating ring 4's rotation but also maintaining its fixed position through friction after rotating to a suitable angle. As the rotating ring 4 rotates, the telescopic bar 7 hinged to its back begins to move. The single hinge lug at the front end of the telescopic bar 7 is hinged to the double hinge lug on the back of the rotating ring 4 via a pivot. As the rotating ring 4 rotates, the telescopic bar 7 swings accordingly. Simultaneously, the slider 14 at the end of the telescopic bar 7 slides within the grooves 15 at both ends of the support bar 8. The telescopic strip 7 and the support strip 8 can be extended and retracted relative to each other. Users can adjust the extension and retraction lengths of the telescopic strip 7 and the support strip 8 according to actual needs to obtain a suitable support angle. When the user is not using the tablet computer 1, when the symmetrical support strips 8 on the back of the protective cover 2 are rotated to the end face of the positioning ring 9, the positioning structure starts to work. The positioning block 10 on the end face of the positioning ring 9 tends to protrude forward under the action of the compression spring 11. When the positioning hole 17 on the support ring 16 is aligned with the positioning block 10, the front end of the positioning block 10 will quickly pass through the positioning hole 17 and be fixed, thereby realizing the storage and protection of the tablet computer 1. When using the tablet computer 1, the user can press the positioning block 10 to make it retract against the elastic force of the compression spring 11, releasing the fixation of the support strip 8. Then, the rotating ring 4 is rotated in the opposite direction to stretch the telescopic strip 7 from the support strip 8, thereby realizing the adjustment of the support angle and height.

[0051] 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.
