Description

Technical Field

[0001] This utility model relates to the field of tablet computer protection devices, and in particular to a multifunctional tablet computer protective case. Background Technology

[0002] With the increasing variety of tablet usage scenarios, foldable protective cases, as a common accessory, still have significant limitations in their functional design. Currently, mainstream products can only provide support at a single angle in landscape or portrait modes, making it difficult to adapt to users' viewing needs in different scenarios, such as the tilted view when lying down or the comfortable angle when operating on a desktop.

[0003] Meanwhile, existing folding protective cases lack sufficient height adjustment capabilities, with most products offering a fixed and low support height. This often forces users to bend over or elevate the device during use, which is neither ergonomic nor conducive to neck fatigue, limiting comfort and health during use.

[0004] Furthermore, this dual limitation of angle and height significantly reduces the practicality of tablets in certain scenarios. Whether it's adjusting the display angle during business presentations or sharing the screen with multiple people for family entertainment, existing protective cases struggle to provide flexible and adaptable support solutions, failing to fully leverage the portability and usability advantages of tablets. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a multifunctional tablet computer protective case. It achieves multiple viewing angles by magnetically connecting different folding units, thus solving the problem of the single support angle of existing folding protective cases. At the same time, the magnetic connection between the folding units can raise the tablet computer, which can meet the different usage requirements and user experience of the tablet computer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional tablet computer protective case includes a base and a panel. The base has a receiving groove for accommodating a tablet computer. The edge of the panel is foldably connected to the edge of the base. The panel includes a first folding unit, a second folding unit, a third folding unit, a fourth folding unit, a fifth folding unit, a sixth folding unit, a seventh folding unit, and an eighth folding unit. The first, second, and third folding units are distributed from top to bottom on the left side of the panel, with a first folding crease between the first and second folding units and a second folding crease between the second and third folding units. The fourth and fifth folding units are located from top to bottom in the center of the panel, with a third folding crease between the fourth folding unit and the first folding unit. A fourth crease is formed between the third fold unit and the fifth fold unit; a fifth crease is formed between the fourth fold unit and the fifth fold unit; the sixth, seventh, and eighth fold units are distributed from top to bottom on the right side of the panel, a sixth crease is formed between the sixth and seventh fold units; a seventh crease is formed between the seventh and eighth fold units; an eighth crease is formed between the sixth and fourth fold units; a ninth crease is formed between the eighth and fifth fold units; the first, second, third, and fourth creases intersect to form a first intersection point; the sixth, seventh, eighth, and ninth creases intersect to form a second intersection point; the fifth crease connects the first and second intersection points.

[0008] As a preferred embodiment: magnets are respectively provided on the upper right and lower right parts of the first folding unit; magnets are provided on the upper right part of the second folding unit; magnets are provided at the bottom of the third folding unit; magnets are respectively provided on the left and right sides of the fourth folding unit; magnets are provided at the bottom of the fifth folding unit; magnets are respectively provided on the upper left and lower left parts of the sixth folding unit; magnets are provided on the upper left part of the seventh folding unit; magnets are provided at the bottom of the eighth folding unit; magnets are respectively provided on the back of the base corresponding to the magnets on the upper right part of the third folding unit, the upper left part of the sixth folding unit, the middle magnets of the third folding unit, the middle magnets of the fourth folding unit, the middle magnets of the fifth folding unit, and the middle magnets of the eighth folding unit. When the panel is flipped in reverse and attached to the back of the base, the corresponding magnets on the base and the panel attract each other.

[0010] As a preferred embodiment, a flexible connection area is provided between the middle of one side edge of the panel and the middle of the corresponding side edge of the base.

[0011] As a preferred embodiment: magnets are respectively provided in the flexible connection area and the top of the back of the base. After the panel is flipped in the opposite direction and attached to the back of the base, the magnets in the flexible connection area and the magnets on the top of the back of the base attract each other.

[0012] As a preferred embodiment: the first folding unit and the sixth folding unit are both irregular quadrilateral shapes; the second folding unit, the third folding unit, the seventh folding unit and the eighth folding unit are all triangular shapes; and the fourth folding unit and the fifth folding unit are both trapezoidal shapes.

[0017] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, as shown in the above technical solution, by setting multiple folding units and creases on the panel, the corresponding folding units on the panel are magnetically connected to magnets cleverly embedded in each folding unit and the base, forming a support structure that can change the different support angles and heights of the tablet computer. This tablet computer case achieves multiple viewing angles through the magnetic connection between different folding units, solving the problem of the single support angle of existing folding cases. Simultaneously, the magnetic connection between the folding units allows the tablet computer to be raised, meeting different user requirements and experiences.

[0018] This tablet case has the following advantages over traditional cases:

[0019] First, in terms of functionality, compared to existing products, the addition of creases in different directions and angles increases the variety of viewing angles and heights for tablets, avoiding the shortcomings of existing products in terms of limited angles and heights.

[0043] Magnets 30 are provided on both the panel 20 and the base 10 of the protective cover, and their specific distribution is as follows ( Figure 14 As shown, the black blocks are magnets 30): Magnets 30 are respectively provided on the upper right and lower right parts of the first folding unit 21; magnets 30 are provided on the upper right part of the second folding unit 22; magnets 30 are provided at the bottom of the third folding unit 23; magnets 30 are provided on the left and right sides of the fourth folding unit 24; magnets 30 are provided at the bottom of the fifth folding unit 25; magnets 30 are provided on the upper left and lower left parts of the sixth folding unit 26; magnets 30 are provided on the upper left part of the seventh folding unit 27; magnets 30 are provided at the bottom of the eighth folding unit 28; magnets 30 are provided on the back of the base 10 corresponding to the magnets 30 on the upper right part of the third folding unit 23, the upper left part of the sixth folding unit 26, the middle part of the third folding unit 23, the middle part of the fourth folding unit 24, the middle part of the fifth folding unit 25, and the middle part of the eighth folding unit 28. When the panel 20 is flipped in the opposite direction and attached to the back of the base 10, the corresponding magnets 30 on the base 10 and the panel 20 attract each other. The lower right of the first folding unit 21, the upper right of the second folding unit 22, the lower left of the sixth folding unit 26, and the upper left of the seventh folding unit 27 each have two rows of magnets 30. The upper row of magnets 30 in the lower right of the first folding unit 21 corresponds to the left side magnets 30 of the fourth folding unit 24. At the same time, the two rows of magnets 30 in the lower right of the first folding unit 21 correspond to the two rows of magnets 30 in the upper right of the second folding unit 22. The upper side magnets 30 in the lower left of the sixth folding unit 26 correspond to the right side magnets 30 of the fourth folding unit 24. At the same time, the two rows of magnets 30 in the lower left of the sixth folding unit 26 correspond to the two rows of magnets 30 in the upper left of the seventh folding unit 27.

[0044] The first folding unit 21, second folding unit 22, and third folding unit 23 on the left side of the panel 20, and the sixth folding unit 26, seventh folding unit 27, and eighth folding unit 28 on the right side of the panel 20, are symmetrical to the fourth folding unit 24 and fifth folding unit 25 in the middle of the panel 20. When the panel 20 is folded to form a support structure, the support structure is also in the center of the protective case, improving the stability of the tablet computer. A flexible connection area 40 is provided between the middle of one edge of the panel 20 and the middle of the corresponding side edge of the base 10. Magnets 30 are respectively provided in the flexible connection area 40 and the top of the back of the base 10. After the panel 20 is flipped over and attached to the back of the base 10, the magnets 30 in the flexible connection area 40 and the top magnets 30 on the back of the base 10 attract each other. The magnets 30 are provided so that the two corresponding folding units can be tightly attracted to each other when the protective case is folded, improving the stability of the support structure when the protective case forms a support structure; and improving the stability of the fit when the panel 20 is flipped over and attached to the back of the base 10.

[0045] The magnets 30 in the panel 20, the back of the base 10, and the flexible connection area 40 are all covered by the protective sleeve surface, which is equivalent to embedding the magnets 30 in the interlayer of the protective sleeve, improving the installation stability of the magnets 30 and the convenience of opening or folding the protective sleeve.

[0046] This tablet case offers three support options during use:

[0047] The first type, such as Figures 5-8 As shown, flip panel 20 to the back of base 10, then fold the first folding unit 21, the second folding unit 22, and the third folding unit 23 from the left to the center; fold the sixth folding unit 26, the seventh folding unit 27, and the eighth folding unit 28 from the right to the center. After folding, the first crease 201 and the sixth crease 206 coincide with the fifth crease 205, respectively. Magnets 30 on the first folding unit 21 and the fourth folding unit 24 attract each other, and magnets 30 on the sixth folding unit 26 and the fourth folding unit 24 attract each other, finally forming as shown. Figure 5 , Figure 6 , Figure 8 The support configuration shown is designed to meet the viewing angle requirements of a user's tablet computer.

[0048] The second type, such as Figure 9 As shown, flipping the first support position backward makes the tablet almost flat on the table (with a tilt angle between the tablet and the table), which can meet the user's writing and drawing angle needs.

[0049] The third type, such as Figure 10-13As shown, after folding the panel 20 to the first support state, the portion above the fifth crease 205, along with the base 10, is folded along the first crease 201, the fifth crease 205, and the sixth crease 206 (the three creases are in an overlapping state, as shown). Figure 6 (As shown) Folding downwards causes the magnets 30 on the first folding unit 21 and the second folding unit 22 to attract each other, and the magnets 30 on the sixth folding unit 26 and the seventh folding unit 27 to attract each other, ultimately forming Figure 10 , Figure 11 and Figure 13 The support configuration allows the tablet to be placed at a higher height, which also changes the viewing angle.

[0050] The key design feature of this invention lies in its use of multiple folding units and creases on the panel. These folding units are then magnetically connected to magnets cleverly embedded within the folding units and the base, creating a support structure that allows for adjustments to the tablet's angle and height. This tablet case achieves multiple viewing angles through the magnetic connection between the folding units, solving the problem of limited support angles in existing folding cases. Furthermore, the magnetic connection between the folding units allows for raising the tablet, satisfying diverse user requirements and experiences.

[0051] This tablet case has the following advantages over traditional cases:

[0052] First, in terms of functionality, compared to existing products, the addition of creases in different directions and angles increases the variety of viewing angles and heights for tablets, avoiding the shortcomings of existing products in terms of limited angles and heights.

[0053] Second, the magnet distribution area has been expanded, making the connection between each folding unit more stable and improving the stability of the tablet computer.

[0054] Third, it enhances protection by effectively preventing the tablet from being scratched or bumped through the combination of the base and the panel.

[0055] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
