DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0028] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] Mobile terminals such as tablets and computers are relatively large in size. For ease of use, they are generally equipped with a protective case with a stand. The protective case with a stand can not only protect the mobile terminal, but also support the mobile terminal, eliminating the need to hold the mobile terminal for viewing.

[0031] However, the current terminal protective cover has a relatively simple support form, and the placement position and placement angle of the mobile terminal are simple, which cannot be applied to special scenarios. For example, when the desktop height is low, the height of the mobile terminal cannot be adjusted, and when the vertical screen needs to be viewed, the terminal protective cover cannot be used.

[0032] The terminal protection cover provided by the embodiment of the utility model is now described.

[0033] Please also read Figures 1 to 7 The terminal protective cover includes a rotating structure 1 and a folding support plate 2 . The folding support plate 2 is connected to the rotating structure 1 , and the rotating structure 1 can rotate relative to the folding support plate 2 .

[0034] The rotating structure 1 is used to fix terminals such as tablets and computers.

[0035] The folding support plate 2 includes a first connecting plate 21, a second connecting plate 22, a third connecting plate 23 and a fourth connecting plate 24 connected in sequence, a first fold 25 is formed between the first connecting plate 21 and the second connecting plate 22, a second fold 26 is formed between the second connecting plate 22 and the third connecting plate 23, and a third fold 27 is formed between the third connecting plate 23 and the fourth connecting plate 24. It can be understood that the second connecting plate 22 can be folded relative to the first connecting plate 21, the third connecting plate 23 can be folded relative to the second connecting plate 22, and the fourth connecting plate 24 can be folded relative to the first connecting plate 21. The first connecting plate 21 and the second connecting plate 22 are used to cover the back of the rotating structure 1, and the third connecting plate 23 and the fourth connecting plate 24 are used to cover the screen of the terminal. The first connecting plate 21 and the rotating structure 1 are connected in an adjustable position, so that the rotating structure 1 can change its position relative to the folding support plate 2, and the terminal protective cover has at least a first use state and a second use state. It can be understood that when the folding support plate 2 is supported on a support surface such as a desktop, the length direction of the terminal protective cover can form at least two different angles with the support surface, that is, the placement angle of the terminal protective cover and the terminal relative to the support surface can be adjusted to facilitate user viewing and use. The folding support plate 2 also has two symmetrically arranged fourth folds 271, and the fourth folds 271 extend from the second connecting plate 22 to the fourth connecting plate 24, so that the terminal protective cover has at least a first support state and a second support state. The height of the rotating structure 1 in the first support state is lower than the height of the rotating structure 1 in the second support state. In this way, the placement height of the rotating structure 1 can be adjusted according to usage requirements.

[0036] Specifically, the terminal protective cover has at least a flattened state, a stored state, a first use state, a second use state, a first support state, and a second support state.

[0037] See also Figure 1 and Figure 2 The terminal protection cover is in a flat state, the first connecting plate 21, the second connecting plate 22, the third connecting plate 23 and the fourth connecting plate 24 are all located on the same plane, and the rotating structure 1 overlaps with the first connecting plate 21 and the second connecting plate 22.

[0038] When the terminal protective cover is in the storage state, the terminal can be located in the terminal protective cover, so that the terminal protective cover wraps and protects the terminal, making it convenient to carry the terminal. In the storage state, the first connecting plate 21 and the second connecting plate 22 are located on the same plane, the rotating structure 1 overlaps with the first connecting plate 21 and the second connecting plate 22, and is arranged on the back of the terminal, and the third connecting plate 23 and the fourth connecting plate 24 cover the screen of the terminal to protect the terminal screen.

[0039] See also Figures 4 to 6 , the terminal protective cover is in the first usage state. In the first usage state, the angle between the rotating structure 1 and the first connecting plate 21 is a first angle. The angle between the rotating structure 1 and the first connecting plate 21 can be understood as the angle between the length direction of the rotating structure 1 and the length direction of the first connecting plate 21.

[0040] See also Figure 7 , the terminal protection cover is in the second use state. In the second use state, the angle between the rotating structure 1 and the first connecting plate 21 is a second angle.

[0041] See also Figure 4 , the terminal protective cover is in the first supporting state. In the first supporting state, the third connecting plate 23 and the fourth connecting plate 24 are supported on a supporting surface such as a desktop, the second connecting plate 22 is inclined, and the side of the second connecting plate 22 away from the third connecting plate 23 abuts against the back of the rotating structure 1 to form a support for the rotating structure 1. At this time, one side of the rotating structure 1 abuts against the third connecting plate 23, or abuts against the fourth connecting plate 24, or abuts against the third fold 27. In other words, when the terminal protective cover is in the first supporting state, one side of the rotating structure 1 is located at the supporting surface, and the rotating structure 1 is placed at a lower position.

[0042] See also Figure 6 and Figure 7 , the terminal protection cover is in the second supporting state. In the second supporting state, the folding support plate 2 is folded along the two fourth creases 271, so that the bottom side of the rotating structure 1 is spaced apart from the supporting surface, which can improve the position of the rotating structure 1.

[0043] The terminal protective cover in the above embodiment includes a rotating structure 1 and a folding support plate 2. The folding support plate 2 includes a first connecting plate 21, a second connecting plate 22, a third connecting plate 23 and a fourth connecting plate 24 that are folded and connected in sequence. By setting a fourth fold 271 extending from the second connecting plate 22 to the fourth connecting plate 24, the folding support plate 2 has at least a first supporting state and a second supporting state. In the two different supporting states, the height of the rotating structure 1 is different, so that the terminal can be used at different heights. At the same time, the rotating structure 1 and the first connecting plate 21 are connected in an adjustable position, so that the terminal protective cover has at least a first use state and a second use state, thereby being able to change the placement direction of the terminal screen to adapt to different use scenarios.

[0044] In some embodiments of the present invention, please refer to Figures 4 to 7When the terminal protective cover is in the first use state, the first angle between the rotating structure 1 and the first connecting plate 21 is 0 degrees, that is, the length direction of the rotating structure 1 and the length direction between the first connecting plates 21 are parallel to each other and parallel to the support surface, and the terminal can be used in landscape mode. When the terminal protective cover is in the second use state, the second angle between the rotating structure 1 and the first connecting plate 21 is 90 degrees, that is, the length direction of the rotating structure 1 and the length direction between the first connecting plates 21 are parallel to each other, and the length direction of the rotating structure 1 is set at an angle to the support surface, and the terminal can be used in portrait mode.

[0045] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 The first fold 25, the second fold 26 and the third fold 27 are arranged parallel to each other, so that the folding support plate 2 is easier to fold and support to form a triangular support structure, and the design and processing are also simpler.

[0046] In some embodiments of the present invention, please refer to Figure 6 and Figure 7 The first connecting plate 21 is rotatably connected to the rotating structure 1, so that the screen of the terminal on the rotating structure 1 can be switched between horizontal placement and vertical placement.

[0047] In some embodiments of the present invention, please refer to Figure 6 and Figure 7 , the rotating structure 1 is detachably connected to the first connecting plate 21 through the magnetic attraction portion. That is, when the terminal screen needs to be placed in a horizontal or vertical direction, the rotating structure 1 is removed from the first connecting plate 21, and then the placement angle of the rotating structure 1 is changed, and then the rotating structure 1 is magnetically placed on the first connecting plate 21. In this way, the terminal screen can be switched between horizontal placement and vertical placement.

[0048] In some embodiments of the present invention, please refer to Figure 3 , Figure 4 and Figure 7 A first magnetic attraction portion 291 and a second magnetic attraction portion 292 are provided on the rotating structure 1, and a third magnetic attraction portion is provided on the first connecting plate 21. In the first usage state, the first magnetic attraction portion 291 and the third magnetic attraction portion are mutually attracted, and in the second usage state, the second magnetic attraction portion 292 and the third magnetic attraction portion are mutually attracted.

[0049] When the terminal protective cover is in the first use state, the first magnetic attraction part 291 and the third magnetic attraction part are mutually attracted, so that the rotating structure 1 is stably connected to the first connecting plate 21. When the terminal protective cover is in the second use state, the second magnetic attraction part 292 and the third magnetic attraction part are mutually attracted, so that the rotating structure 1 is stably connected to the first connecting plate 21. When the terminal protective cover needs to be switched between the first use state and the second use state, the rotating structure 1 can be rotated relative to the first connecting plate 21.

[0050] By setting the first magnetic attraction part 291 and the third magnetic attraction part, the terminal protective cover can be kept stable in the first use state, and by setting the second magnetic attraction part 292 and the third magnetic attraction part, the terminal protective cover can be kept stable in the second use state. Fixing the rotating structure 1 and the first connecting plate 21 by magnetic attraction makes it easier to switch between the first use state and the second use state, and the placement angle of the terminal is easier to adjust.

[0051] Optionally, a fourth magnetic portion is provided on the second connecting plate 22. When the terminal protective cover is in the second usage state and the second supporting state, the fourth magnetic portion and part of the second magnetic portion 292 on the rotating structure 1 are mutually attracted, and the third magnetic portion and the remaining part of the second magnetic portion 292 are mutually attracted, thereby making the terminal protective cover more stable in the second usage state.

[0052] In other embodiments, the terminal protective cover also has a third use state, a fourth use state, etc., such as 45 degrees, 135 degrees, etc. Accordingly, the rotating structure 1 is provided with a magnetic attraction structure to keep the terminal protective cover in the third use state, the fourth use state, etc.

[0053] In some embodiments of the present invention, please refer to Figure 3 The first magnetic attraction portion 291 includes a first magnetic attraction group 2911 extending along the first direction, the second magnetic attraction portion 292 includes a second magnetic attraction group 2921 extending along the second direction; the third magnetic attraction portion includes a third magnetic attraction group extending along the first direction; the first direction and the second direction are perpendicular to each other.

[0054] The first magnetic group 2911 and the third magnetic group both extend along the first direction, so that the first magnetic group 2911 and the third magnetic group can be stably adsorbed, and the second magnetic group 2921 extends along the second direction, so that the second magnetic group 2921 and the third magnetic group can be stably adsorbed.

[0055] By setting the first magnetic attraction portion 291 and the third magnetic attraction portion as a magnetic attraction group extending in the first direction, and setting the second magnetic attraction portion 292 as a magnetic attraction group extending in the second direction, the magnetic attraction force between the first connecting plate 21 and the rotating structure 1 is large, and the terminal protective cover can be stably maintained in the first use state and the second use state. The first direction and the second direction are perpendicular to each other, which facilitates the design and layout of the magnetic attraction group.

[0056] In some embodiments, see Figure 3 In the rotating structure 1, the number of the first magnetic attraction groups 2911 is two, and the two first magnetic attraction groups 2911 are arranged at intervals along the second direction. The number of the second magnetic attraction groups 2921 is also two, and the two second magnetic attraction groups 2921 are arranged at intervals along the first direction. The two first magnetic attraction groups 2911 and the two second magnetic attraction groups 2921 form a square magnetic group. Moreover, after the rotating structure 1 rotates 90 degrees relative to the first connecting plate 21, the layout of the square magnetic group does not change, and there is no need to distinguish between the first magnetic attraction group 2911 and the second magnetic attraction group 2921. In this embodiment, the terminal protective cover has a large number of magnets that adsorb each other in both use states, thereby ensuring stability in use.

[0057] In some embodiments, the first magnetic group 2911 and the second magnetic group 2921 are arranged in a cross shape, and the third magnetic group is arranged in a strip shape. After the rotating structure 1 rotates 90 degrees relative to the first connecting plate 21, the layout of the magnets thereon does not change. In both usage states, the terminal protective cover has a large number of magnets that adsorb each other, thereby ensuring stability of use.

[0058] In some embodiments of the utility model, the surface of the rotating structure 1 is made of leather. When the terminal protective cover is in the first supporting state, the side of the folding support plate 2 used for supporting and abutting the rotating structure 1 is made of leather, suede or suede, so that the friction between one side of the rotating structure 1 and the folding support plate 2 when supporting and abutting can be increased to prevent the rotating structure 1 from slipping.

[0059] In some embodiments of the present invention, please refer to Figure 4 The rotating structure 1 has a thrust structure, and in the first supporting state, the thrust structure is used to abut against the folding support plate 2. Specifically, when the terminal protective cover is in the first supporting state, the thrust structure abuts against the third connecting plate 23, the fourth connecting plate 24 or the third fold 27. The setting of the thrust structure is used to enhance the friction between the rotating structure 1 and the folding support plate 2, so that the terminal protective cover is more stable in the first supporting state and will not slip.

[0060] In some embodiments, the thrust structure increases the friction between it and the folding support plate 2 by changing its surface material. For example, the thrust structure is made of materials such as silicone and rubber.

[0061] In some embodiments, the thrust structure is disposed on a side of the rotating structure 1 away from the first connecting plate 21 , so that the protruding structure abuts against the folding support plate 2 .

[0062] In some embodiments, the thrust structure is a dot-shaped, pattern-shaped, strip-shaped or other protruding structure, and its specific shape is not limited here. For example, when the protruding structure is a plurality of strip-shaped units, the strip-shaped units can be distributed in sequence along the length direction of the rotating structure 1.

[0063] In some embodiments of the present invention, please refer to Figure 2 and Figure 5 The terminal protection cover also has a third supporting state. In the third supporting state, the side of the first connecting plate 21 close to the first fold 25 and the side of the fourth connecting plate 24 away from the third fold 27 abut against each other; the first connecting plate 21 is provided with a fifth magnetic attraction portion 293 on the side close to the first fold 25, and the fourth connecting plate 24 is provided with a sixth magnetic attraction portion 294 on the side away from the third fold 27 for mutual adsorption with the fifth magnetic attraction portion 293.

[0064] See also Figure 5 , the terminal protective cover is in the third supporting state. In the third supporting state, the first connecting plate 21 and the second connecting plate 22 are both arranged coplanarly with the back of the rotating structure 1, the third connecting plate 23 is supported on a supporting surface such as a desktop, and the end of the fourth connecting plate 24 away from the third connecting plate 23 is supported on the back of the rotating structure 1 (at the first fold 25). In this way, when the terminal protective cover is in the third supporting state, the side of the first connecting plate 21 close to the first fold 25 and the side of the fourth connecting plate 24 away from the third fold 27 abut against each other. By setting the fifth magnetic attraction part 293 and the sixth magnetic attraction part 294, the terminal protective cover can be stably maintained in the third supporting state, enriching the supporting state of the terminal protective cover, so that the rotating structure 1 has a richer tilt angle, and the tilt angle of the terminal screen is also richer.

[0065] Optionally, the fifth magnetic attraction portion 293 includes a plurality of third magnetic attraction units sequentially spaced along the length direction of the first connecting plate 21. The sixth magnetic attraction portion 294 includes a plurality of fourth magnetic attraction units sequentially spaced along the length direction of the fourth connecting plate 24. This can save the cost of the magnetic attraction portion.

[0066] In some embodiments of the present invention, please refer to Figure 2 , a buckle 28 is provided on the side of the first connecting plate 21 away from the first fold 25, and the buckle 28 is used to fix to the fourth connecting plate 24 when the terminal protective cover is in the storage state. When the terminal protective cover is in the storage state, the first connecting plate 21 and the second connecting plate 22 are one plate, and the third connecting plate 23 and the fourth connecting plate 24 are one plate. The two plates are folded through the second fold 26, so that the third connecting plate 23 and the fourth connecting plate 24 cover the screen of the terminal. The buckle 28 on the first connecting plate 21 is fixed to the fourth connecting plate 24, so that the two plates can be fixed to each other, and the third connecting plate 23 and the fourth connecting plate 24 will not be separated from the terminal screen.

[0067] By setting the buckle 28, the terminal protective cover can be closely attached to the terminal when in the storage state, so as to always wrap and protect the terminal.

[0068] In other embodiments, a binding strap may also be provided on the first connecting plate 21 , with two ends of the binding strap respectively connected to two sides of the length direction of the first connecting plate 21 , and the fourth connecting plate 24 may be fixed by the binding strap.

[0069] In some embodiments, the buckle 28 can be fixed to the fourth connecting plate 24 by means of snap fasteners or the like.

[0070] In some embodiments of the present invention, please refer to Figure 2 When the terminal protective shell is in the storage state, the buckle 28 is fixed to the fourth connecting plate 24 by magnetic attraction. Specifically, the buckle 28 is provided with a seventh magnetic attraction portion 295, and the fourth connecting plate 24 is provided with an eighth magnetic attraction portion 296. In the storage state, the seventh magnetic attraction portion 295 and the eighth magnetic attraction portion 296 are mutually attracted. When the terminal protective cover is opened, the buckle 28 is removed from the fourth connecting plate 24, and the seventh magnetic attraction portion 295 and the eighth magnetic attraction portion 296 are separated from each other. In this way, the terminal protective cover can switch between the storage state and the open state (flat state, support state, etc.) quickly and is easy to operate.

[0071] Optionally, the seventh magnetic attraction portion 295 includes a plurality of fifth magnetic attraction units sequentially distributed along the length direction of the fourth connecting plate 24 , and the eighth magnetic attraction portion 296 includes a plurality of sixth magnetic attraction units sequentially distributed along the length direction of the fourth connecting plate 24 .

[0072] In some embodiments of the present invention, please refer to Figure 2 , a ninth magnetic attraction portion 297 is also provided on the fourth connecting plate 24. When the seventh magnetic attraction portion 295 and the ninth magnetic attraction portion 297 are attracted to each other, a storage space for accommodating a stylus pen is formed between the buckle 28 and the rotating structure 1. The seventh magnetic attraction portion 295 is provided on the buckle 28. When the seventh magnetic attraction portion 295 is attracted to the ninth magnetic attraction portion 297 on the fourth connecting plate 24, there is a storage space between the inner surface of the buckle 28 and the side surface of the rotating structure 1, which is just enough for the stylus pen to be placed. When the seventh magnetic attraction portion 295 and the eighth magnetic attraction portion 296 are attracted to each other, the inner surface of the buckle 28 and the side surface of the rotating structure 1 are tightly attached to each other, and there is no storage space for placing the stylus pen. In this way, the terminal protective cover can not only protect the terminal tightly when there is no stylus pen, but also store the stylus pen when there is a stylus pen, thereby enriching the functions of the terminal protective cover.

[0073] In which, taking the fourth connecting plate 24 away from the third fold 27 as a reference side, the distance between the ninth magnetic attraction portion 297 and the reference side is smaller than the distance between the eighth magnetic attraction portion 296 and the reference side.

[0074] Optionally, the ninth magnetic attraction portion 297 includes a plurality of seventh magnetic attraction units sequentially distributed along the length direction of the fourth connecting plate 24 .

[0075] In some embodiments of the present invention, please refer to Figure 2 , a tenth magnetic attraction portion 298 for adsorbing the seventh magnetic attraction portion 295 is provided on the first connecting plate 21. When the terminal protective shell is in the storage state, the buckle 28 is fixed to the fourth fixing plate along the first direction.
