Description

TECHNICAL FIELD

[0001] The present application relates to a protective sleeve, and more particularly to a protective sleeve for an electronic device. BACKGROUND

[0002] A tablet computer (e.g. a smart phone or a tablet computer) is a very popular portable electronic device. In order to expand the functions of the tablet computer or to avoid the tablet computer from colliding with other objects when carrying, many people will add a protective sleeve to the tablet computer.

[0003] For a foldable protective sleeve, the cover plate is usually composed of a plurality of plate blocks, and the plurality of plate blocks can swing relative to each other to fold into a support, which can be used to support the tablet computer to provide a better viewing angle. However, after the cover plate of the protective sleeve is opened, if each plate block is not further intervened by an external force, the swinging direction of each plate block will not be controlled, so the user must press each plate block by hand again to successfully fold the plurality of plate blocks into the expected support type, which causes inconvenience and trouble in use. SUMMARY

[0004] In view of the above, in one embodiment, a protective sleeve for an electronic device is provided, which includes a first plate body, a flexible bending piece, and a second plate body. The flexible bending piece is connected between the first plate body and the second plate body, so that the first plate body and the second plate body can be folded or unfolded relative to each other. The first plate body includes a first outer surface layer, a first inner surface layer, and a plurality of movable plate blocks. The surface of the first outer surface layer has a first outer adhesive layer, and the surface of the first inner surface layer has a first inner adhesive layer. The plurality of movable plate blocks are adhered between the first outer adhesive layer and the first inner adhesive layer, and are spaced apart from each other, so that the plurality of movable plate blocks can swing relative to each other. The flexible bending piece includes a flexible outer layer, a flexible inner layer, and a thermoplastic shaping adhesive layer. The thermoplastic shaping adhesive layer is adhered between the flexible outer layer and the flexible inner layer, so that the flexible bending piece is maintained in a curved state.

[0005] In another embodiment, a method for manufacturing a protective case for an electronic device includes preparing an outer skin and an inner skin, wherein the outer skin includes a first outer layer and a flexible outer layer integrally connected, and the inner skin includes a first inner layer and a flexible inner layer integrally connected; disposing a first outer adhesive layer on a surface of the first outer layer, a first inner adhesive layer on a surface of the first inner layer, and a thermoplastic adhesive layer between the flexible outer layer and the flexible inner layer; adhering a plurality of movable plate blocks between the first outer adhesive layer and the first inner adhesive layer, and adhering the thermoplastic adhesive layer between the flexible outer layer and the flexible inner layer, wherein the plurality of movable plate blocks are spaced apart from each other such that the plurality of movable plate blocks can swing relative to each other; heating the thermoplastic adhesive layer and bending the flexible outer layer, the thermoplastic adhesive layer, and the flexible inner layer; and cooling the thermoplastic adhesive layer to form a thermoplastic set adhesive layer, such that the flexible outer layer, the thermoplastic set adhesive layer, and the flexible inner layer form a flexible bending piece, and the flexible bending piece is maintained in a bent state.

[0006] In summary, according to the protective case for an electronic device of the embodiment of the present application, the adhesive layer between the flexible outer layer and the flexible inner layer of the flexible bending piece is a thermoplastic set adhesive layer, such that the flexible bending piece can be maintained in a bent state. Thus, when the first plate body and the second plate body are unfolded relative to each other, the flexible bending piece can generate a torsion force to drive the plurality of movable plate blocks of the first plate body to swing relative to each other to form a predetermined use mode. In addition, when the first plate body and the second plate body are closed to each other, the above-mentioned torsion force can also prevent the first plate body and the second plate body from being easily separated to improve the protection effect.

[0058] Figure 1 This is a perspective view of one embodiment of the protective sleeve of the present invention. Figure 2 This is an exploded perspective view of one embodiment of the protective sleeve of the present invention. Figure 3 This is a partial cross-sectional view of one embodiment of the protective sleeve of the present invention. Figures 1 to 3 As shown, the protective sleeve 2 of this embodiment includes a first plate 10, a second plate 20, and a flexible bending piece 30, which is connected between the first plate 10 and the second plate 20. The flexible bending piece 30 is made of a flexible material, such as leather, silicone, or plastic, allowing the first plate 10 and the second plate 20 to overlap or unfold relative to each other due to the flexible properties of the flexible bending piece 30.

[0059] like Figure 1 and Figure 2As shown, the first plate body 10 of the protective sleeve 2 is used for assembling the electronic device 1, for example, the electronic device 1 can be a smart phone or a tablet computer, etc. In some embodiments, the assembly between the first plate body 10 and the electronic device 1 can be achieved by magnetic attraction, buckle or adhesive buckle, etc., and the electronic device 1 can be detached from the first plate body 10.

[0060] As shown, Figures 1 to 3 The first plate body 10 includes a first outer surface layer 11, a first inner surface layer 13 and a plurality of movable plate blocks, in this embodiment, the plurality of movable plate blocks include a first movable plate block 15, a second movable plate block 16 and a third movable plate block 17, but the number of movable plate blocks is not limited thereto. In addition, the surface of the first outer surface layer 11 has a first outer adhesive layer 12, and the surface of the first inner surface layer 13 has a first inner adhesive layer 14. The first movable plate block 15, the second movable plate block 16 and the third movable plate block 17 are adhered between the first outer adhesive layer 12 and the first inner adhesive layer 14, so that the first movable plate block 15, the second movable plate block 16 and the third movable plate block 17 are covered inside the first outer surface layer 11 and the first inner surface layer 13.

[0061] As shown, Figures 1 to 3 In this embodiment, the first movable plate block 15, the second movable plate block 16 and the third movable plate block 17 are rectangular and have the same length, in addition, the width of the third movable plate block 17 is greater than the width of the first movable plate block 15, and the width of the first movable plate block 15 is greater than the width of the second movable plate block 16, but this is not limited, the shape, length and width of the first movable plate block 15, the second movable plate block 16 and the third movable plate block 17 can be different according to the actual product demand.

[0062] As shown, Figure 1 As shown, Figure 3 The first movable plate block 15, the second movable plate block 16 and the third movable plate block 17 are spaced apart from each other, so that the first outer surface layer 11 and the first inner surface layer 13 are located in the local area between the first movable plate block 15 and the second movable plate block 16 to form a first flexible part 18, thereby the first movable plate block 15 and the second movable plate block 16 can rotate relative to each other through the flexible characteristics of the first flexible part 18. The local area between the second movable plate block 16 and the third movable plate block 17 of the first outer surface layer 11 and the first inner surface layer 13 forms a second flexible part 19, so that the second movable plate block 16 and the third movable plate block 17 can rotate relative to each other through the flexible characteristics of the second flexible part 19. In addition, in this embodiment, the second movable plate block 16 is located between the first movable plate block 15 and the third movable plate block 17, and the first movable plate block 15 is adjacent to the flexible bending piece 30 relative to the second movable plate block 16 and the third movable plate block 17.

[0063] As shown, Figure 2 As shown, Figure 3As shown, the second plate body 20 comprises a connecting piece 21 and a base plate 25, the connecting piece 21 is integrally connected to the flexible bending piece 30 and fixed to the base plate 25, for example, the connecting piece 21 can be fixed to the base plate 25 by means of adhesion, buckling or locking, etc. In this embodiment, the second plate body 20 is also provided with a keyboard 26 (such as a physical keyboard or a touch keyboard), when the electronic device 1 is assembled to the first plate body 10, the keyboard 26 can be connected to the electronic device 1 by wired or wireless manner, so that the keyboard 26 can be used to control the electronic device 1 to input information.

[0064] As shown in the drawings, Figure 2 As shown in the drawings, Figure 3 As shown, the flexible bending piece 30 comprises a flexible outer layer 31, a flexible inner layer 32 and a thermoplastic shaping glue layer 33, and the thermoplastic shaping glue layer 33 is adhered between the flexible outer layer 31 and the flexible inner layer 32, so that the flexible bending piece 30 is maintained in a curved state. In some embodiments, the thickness of the above-mentioned thermoplastic shaping glue layer 33 can be greater than the sum of the thickness of the above-mentioned first outer glue layer 12 and the thickness of the first inner glue layer 14, but this is not limited.

[0065] As shown, the thermoplastic shaping glue layer 33 of the flexible bending piece 30 is first heated and plasticized to form a curved state, and then hardened and shaped after cooling, so that after the thermoplastic shaping glue layer 33 is adhered between the flexible outer layer 31 and the flexible inner layer 32, the flexible bending piece 30 as a whole can be maintained in the above-mentioned curved state, therefore, the flexible bending piece 30 can continuously generate a torsion force F in the bending direction thereof, and when the flexible bending piece 30 is forced to swing or bend in the opposite direction of the bending direction, the above-mentioned torsion force F will be further increased, which is described in conjunction with the drawings as follows.

[0066] Figure 4 It is an unfolded schematic view of an embodiment of the protective sleeve of the present application, Figure 5 It is a use state view of an embodiment of the protective sleeve of the present application. Please refer to Figures 3 to 5 As shown, since the flexible bending piece 30 is in a curved and shaped state, the flexible bending piece 30 can continuously generate a torsion force F in the bending direction thereof, as shown in the drawings, Figure 4 The direction of the above-mentioned torsion force F is the direction of covering the first plate body 10 on the second plate body 20. In addition, when the first plate body 10 and the second plate body 20 are unfolded relative to each other, for example, from the perspective of Figure 4 The first plate body 10 swings and unfolds relative to the second plate body 20 in the clockwise direction (as shown by the direction of the arrow L), so that the flexible bending piece 30 is forced to swing or bend in the opposite direction of the bending direction thereof, thereby making the flexible bending piece 30 generate a greater torsion force F (as shown in the drawings), Figure 4As shown, the direction of the torque F is counterclockwise (opposite to the clockwise unfolding direction of the first plate 10), and the torque F can be applied to the first movable plate 15 closest to the flexible bending piece 30. Therefore, during the unfolding of the first plate 10, the first movable plate 15 can swing in the direction of the torque F, thereby causing the other movable plates (the second movable plate 16 and the third movable plate 17) to move relative to each other, so that the first movable plate 15, the second movable plate 16, and the third movable plate 17 can automatically fold into a predetermined usage configuration (such as...). Figure 5 As shown, the electronic device 1 is supported, so the user no longer needs to apply pressure to adjust the moving parts by hand, thus improving the convenience of use.

[0067] like Figure 5 As shown, the predetermined usage configuration can be such that the angle between the first movable plate 15 and the second plate 20 is an acute angle, the angle between the first movable plate 15 and the second movable plate 16 is an obtuse angle, and the second movable plate 16 and the third movable plate 17 are stacked on top of each other and parallel to each other, so that the first movable plate 15, the second movable plate 16 and the third movable plate 17 are folded into a three-dimensional support configuration. Therefore, when the electronic device 1 rests against the third movable plate 17, it can be supported and placed in an inclined state. However, the above embodiment is only an example, and the first movable plate 15, the second movable plate 16 and the third movable plate 17 can also be designed into different folding configurations based on different usage requirements.

[0068] Furthermore, when the first plate 10 and the second plate 20 are closed together (e.g.) Figure 3 As shown, the torque F of the flexible bending piece 30 can also prevent the first plate 10 and the second plate 20 from easily separating, thus improving the protective effect. For example, when the protective case 2 comes into contact with a foreign object during carrying, causing the first plate 10 and the second plate 20 to open, the flexible bending piece 30 can generate a torque F to close the first plate 10 and the second plate 20, thereby preventing dust or foreign objects from entering or causing damage to the screen of the electronic device 1. The manufacturing method of the protective case 2 according to an embodiment of the present invention will be further described below with reference to the accompanying drawings.

[0069] Figure 6 This is a flowchart illustrating the steps of manufacturing the protective sleeve of the present invention. Figure 7 This is a partial side view of one embodiment of the protective sleeve of the present invention. Figure 8 This is a partial cross-sectional view of a first embodiment of the thermoplastic adhesive layer of the protective sleeve of the present invention. (See attached image.) Figure 6 As shown, the manufacturing method of the protective sleeve 2 in this embodiment of the invention includes steps S01 to S05. In step S01: an outer skin 40 and an inner skin 50 are prepared. Please refer to... Figure 7 and Figure 8As shown, the outer skin 40 includes a first outer surface layer 11 and a flexible outer layer 31 integrally connected, and the inner skin 50 includes a first inner surface layer 13 and a flexible inner layer 32 integrally connected. In some embodiments, the materials of the outer skin 40 and the inner skin 50 may be soft materials such as leather, silicone, or plastic.

[0070] like Figure 6 As shown, step S02 can be executed after step S01: a first outer adhesive layer 12 is disposed on the surface of the first outer surface layer 11, a first inner adhesive layer 14 is disposed on the surface of the first inner surface layer 13, and a thermoplastic adhesive layer 60 is disposed between the flexible outer layer 31 and the flexible inner layer 32. The thickness of the thermoplastic adhesive layer 60 can be greater than the sum of the thicknesses of the first outer adhesive layer 12 and the first inner adhesive layer 14. Please refer to... Figure 7 and Figure 8 As shown, in this embodiment, the thermoplastic adhesive layer 60 includes an outer adhesive layer 34, an inner adhesive layer 35, and a thickened adhesive layer 36, wherein the thickened adhesive layer 36 can be a single layer or multiple layers of adhesive, for example, in... Figure 8 In one embodiment, the thickened adhesive layer 36 is a double-layer adhesive, comprising an outer thickened adhesive layer 361 and an inner thickened adhesive layer 362.

[0071] For example Figure 8 As shown, the first outer adhesive layer 12 and the outer adhesive layer 34 can be integrally connected as the same adhesive layer with the same thickness, and the first inner adhesive layer 14 and the inner adhesive layer 35 can be integrally connected as the same adhesive layer with the same thickness. Therefore, in step S02, the first outer adhesive layer 12 and the outer adhesive layer 34 can be applied or attached together to the surface of the first outer surface layer 11 and the flexible outer layer 31 by hand or machine, and the first inner adhesive layer 14 and the inner adhesive layer 35 can be applied or attached together to the surface of the first inner surface layer 13 and the flexible inner layer 32. Next, the outer thickening adhesive layer 361 is applied or attached to the surface of the outer adhesive layer 34 and the inner thickening adhesive layer 362 is applied or attached to the surface of the inner adhesive layer 35. The thickness of the outer adhesive layer 34, the inner adhesive layer 35 and the thickening adhesive layer 36 after stacking the thermoplastic adhesive layer 60 is greater than the sum of the thicknesses of the first outer adhesive layer 12 and the first inner adhesive layer 14.

[0072] In some embodiments, the thickness of the outer thickening adhesive layer 361 may be the same as the thickness of the outer adhesive layer 34, and the thickness of the inner thickening adhesive layer 362 may be the same as the thickness of the inner adhesive layer 35, so that the thickness of the outer adhesive layer 34, the inner adhesive layer 35, and the thickening adhesive layer 36 after stacking is twice the sum of the thicknesses of the first outer adhesive layer 12 and the first inner adhesive layer 14 (e.g., Figure 8 (As shown). Or, as... Figure 9As shown, in another embodiment, the thickness of the outer thickening adhesive layer 361 can be greater than the thickness of the outer adhesive layer 34, and the thickness of the inner thickening adhesive layer 362 can be greater than the thickness of the inner adhesive layer 35, so that the thickness of the outer adhesive layer 34, the inner adhesive layer 35 and the thickening adhesive layer 36 after stacking is greater than twice the sum of the thicknesses of the first outer adhesive layer 12 and the first inner adhesive layer 14.

[0073] Or, such as Figure 10 As shown, in another embodiment, the thickening adhesive layer 36 of the thermoplastic adhesive layer 60 may also be a three-layer adhesive, including an outer thickening adhesive layer 361, an inner thickening adhesive layer 362, and a middle thickening adhesive layer 363. In step S02, the middle thickening adhesive layer 363 may be adhered to the outer thickening adhesive layer 361 or the inner thickening adhesive layer 362. Alternatively, the thickening adhesive layer 36 of the thermoplastic adhesive layer 60 may also be a single-layer adhesive, including only the aforementioned outer thickening adhesive layer 361, inner thickening adhesive layer 362, or middle thickening adhesive layer 363, for example... Figure 11 As shown, in this embodiment, the thickened adhesive layer 36 of the thermoplastic adhesive layer 60 only includes the intermediate thickened adhesive layer 363.

[0074] Additionally, it should be noted that, for the sake of narrative convenience and clarity, Figures 8 to 11 The thickness or size of each adhesive layer and the joints between each adhesive layer are expressed in an exaggerated or approximate manner to help those skilled in the art understand the thickness relationship between the adhesive layers, and are not their actual dimensions. This is stated here first.

[0075] like Figure 6 As shown, step S03 can be performed after step S02: adhering multiple movable plates between the first outer adhesive layer 12 and the first inner adhesive layer 14, and adhering the thermoplastic adhesive layer 60 to the flexible outer layer 31 and the flexible inner layer 32. Please refer to this. Figure 2 As shown above, the multiple movable panels include a first movable panel 15, a second movable panel 16, and a third movable panel 17 arranged at intervals between each other, so that the multiple movable panels can swing relative to each other after being adhered between the first outer adhesive layer 12 and the first inner adhesive layer 14.

[0076] like Figure 6 As shown, after step S03, step S04 can be performed: heating the thermoplastic layer 60, the flexible outer layer 31, the thermoplastic layer 60, and the flexible inner layer 32. Please refer to... Figure 12 and Figure 13 As shown, in step S04, the thermoplastic layer 60 can first be heated to a predetermined temperature by the heater 70 (e.g., Figure 12 As shown), the thermoplastic layer 60 is softened and made deformable. Then, the flexible outer layer 31, the thermoplastic layer 60, and the flexible inner layer 32 are bent into a predetermined bending state using a tool 71 (as shown). Figure 13 (As shown). Or, as... Figure 14As shown, in step S04, the flexible outer layer 31, thermoplastic layer 60 and flexible inner layer 32 can be bent into a predetermined bending state by tool 71 first, and then the thermoplastic layer 60 can be heated to a predetermined temperature by heater 70 to soften it.

[0077] like Figure 6 As shown, after step S04, step S05 can be performed: cooling the thermoplastic layer 60 to form the thermoplastic shaping layer 33. For example, in step S05, the thermoplastic layer 60 can be left to stand for a period of time to allow it to cool naturally, or the thermoplastic layer 60 can be cooled more quickly by a cooling device (e.g., a fan), so that the thermoplastic layer 60 solidifies to form the aforementioned thermoplastic shaping layer 33, which can maintain the aforementioned bent state (e.g., Figure 13 or Figure 14 (As shown). Therefore, the flexible outer layer 31, the thermoplastic shaping layer 33, and the flexible inner layer 32 can form a flexible bending sheet 30, and the flexible bending sheet 30 is maintained in the above-mentioned bending state (as shown). Figure 3 (As shown).

[0078] Please refer to this. Figure 3 and Figure 15 As shown, since the thermoplastic shaping adhesive layer 33 is formed by curing the aforementioned thermoplastic adhesive layer 60, the thermoplastic shaping adhesive layer 33 of the flexible bending sheet 30 also includes an outer adhesive layer 34, an inner adhesive layer 35, and a thickening adhesive layer 36, with the thickening adhesive layer 36 adhering between the outer adhesive layer 34 and the inner adhesive layer 35. Furthermore, as mentioned above, the thickening adhesive layer 36 of the thermoplastic shaping adhesive layer 33 can be a multilayer adhesive including at least two of the outer thickening adhesive layer 361, the inner thickening adhesive layer 362, and the intermediate thickening adhesive layer 363, or the thickening adhesive layer 36 can be a single layer adhesive including only the aforementioned outer thickening adhesive layer 361, the inner thickening adhesive layer 362, or the intermediate thickening adhesive layer 363, such that the thickness of the thermoplastic shaping adhesive layer 33 is greater than the sum of the thicknesses of the first outer adhesive layer 12 and the first inner adhesive layer 14.

[0079] Please check again Figure 4 and Figure 15 As shown, the thickness of the thermoplastic shaping adhesive layer 33 of the flexible bending sheet 30 is greater than the sum of the thicknesses of the first outer adhesive layer 12 and the first inner adhesive layer 14, so that the thermoplastic shaping adhesive layer 33 has sufficient rigidity to provide torque F. Therefore, during the unfolding process of the first plate 10, the torque F can drive multiple movable panels to automatically fold into a predetermined usage configuration (such as...). Figure 5 (As shown). In addition, the greater the thickness of the thermoplastic shaping layer 33 of the flexible bending sheet 30, the greater the torque F generated by the flexible bending sheet 30 under stress. Therefore, the thickness of the thermoplastic shaping layer 33 can be adjusted according to the actual needs of the product.

[0080] Additionally, in step S03 above, a portion of the thickened adhesive layer 36 can be adhered to the movable plate adjacent to the flexible bending sheet 30. For example... Figure 2 As shown, the first movable plate 15 is adjacent to the flexible bending piece 30 relative to the second movable plate 16 and the third movable plate 17. A portion of the thickened adhesive layer 36 can be adhered to the surface or interlayer of the first movable plate 15, so that when the flexible bending piece 30 generates torque F, the torque F can be transmitted to the first movable plate 15 more quickly.

[0081] For example, such as Figure 8 and Figure 9 As shown, in this embodiment, the thickened adhesive layer 36 includes an outer thickened adhesive layer 361 and an inner thickened adhesive layer 362. One side of the outer thickened adhesive layer 361 and one side of the inner thickened adhesive layer 362 are respectively adhered to two opposite surfaces of the first movable plate 15. Alternatively, as... Figure 10 In this embodiment, the first movable plate 15 includes multiple plates 151 stacked on top of each other. The thickened adhesive layer 36 includes an outer thickened adhesive layer 361, an inner thickened adhesive layer 362, and a middle thickened adhesive layer 363. One side of the middle thickened adhesive layer 363 is sandwiched and adhered between the multiple plates 151, and one side of the outer thickened adhesive layer 361 and one side of the inner thickened adhesive layer 362 are respectively adhered to two opposite surfaces of the first movable plate 15. Alternatively, as... Figure 11 As shown, in this embodiment, the thickened adhesive layer 36 only includes the intermediate thickened adhesive layer 363, and one side of the intermediate thickened adhesive layer 363 is sandwiched and adhered between the plurality of plates 151 of the first movable plate 15.

[0082] Although the technical content of the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention should be included within the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
