The third plate is movably connected to the side of the second plate away from the first plate, and the fourth plate is movably connected to the third plate and the fifth plate, so that the cover plate can support the second plate by folding.

[0009] Optionally, the second plate is provided with a third magnetic attraction structure, and the fifth plate is provided with a fourth magnetic attraction structure. When the cover plate is folded up to support the second plate, the third magnetic attraction structure and the fourth magnetic attraction structure attract each other.

[0010] Optionally, both the first magnetic attraction structure and the second magnetic attraction structure are bar magnets that extend along the length direction of the back plate.

[0011] Optionally, the back plate is provided with a first connecting structure, and the protective sleeve further includes a flexible strip.

The shell is used to connect with a mobile terminal. The back plate includes a first plate and a second plate arranged sequentially in its width direction. A first magnetic attraction structure is provided on the back side of the shell. A second magnetic attraction structure is provided on the first plate to attract the first magnetic attraction structure, so that the shell can be installed on the first plate. The cover plate is movably connected to the side of the second plate away from the first plate, so that the cover plate can support the second plate by folding, thereby allowing the mobile terminal to be placed tilted on the table.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] This utility model embodiment provides a protective cover 1000, such as Figures 1-4 and Figures 7-9As shown, the protective cover 1000 includes a shell 100, a back plate 200, and a cover plate 300. At least two first magnetic structures 110 are provided on the back side of the shell 100, and multiple first magnetic structures 110 are sequentially arranged in the width direction of the shell 100. The back plate 200 includes a first plate 210 and a second plate 220 sequentially arranged in its width direction. A second magnetic structure 211 is provided on the first plate 210, and the second magnetic structure 211 attracts the first magnetic structure 110, allowing the shell 100 to be mounted on the first plate 210. The first plate 210 and the second plate 220 are rotatably connected to adjust the angle between them. The cover plate 300 is movably connected to the side of the second plate 220 away from the first plate 210, and the cover plate 300 can support the second plate 220 by folding.

[0039] Firstly, the user can fold the cover plate 300 to support the second plate 220. Since the second plate 220 is connected to the first plate 210 and the housing 100 is connected to the first plate 210, the cover plate 300 can be used to support the housing 100, so that the mobile terminal connected to the housing 100 can be placed on the table in an inclined position, freeing the user's hands.

[0040] Secondly, in this embodiment, the second plate 220 is rotatably connected to the first plate 210, so the angle between the second plate 220 and the first plate 210 can be adjusted. Since the housing 100 is connected to the first plate 210 and the cover plate 300 is supported by the second plate 220, adjusting the angle between the second plate 220 and the first plate 210 means adjusting the tilt angle of the mobile terminal. Therefore, the protective cover 1000 of this embodiment can meet the different tilt angle requirements of different users.

[0041] Thirdly, in this embodiment, there are two first magnetic structures 110, and multiple first magnetic structures 110 are arranged sequentially in the width direction of the housing 100. Therefore, the second magnetic structure 211 can adjust the usage height of the mobile terminal by cooperating with different first magnetic structures 110 to meet the different usage height requirements of different users.

[0042] Therefore, the protective case 1000 provided in this embodiment can not only adjust the tilt angle of the mobile terminal when supporting it, but also adjust its height, resulting in an excellent user experience.

[0043] This utility model embodiment also provides a protective cover 1000, such as Figures 1-2 and Figures 5-9As shown, the protective cover 1000 includes a shell 100, a back plate 200, and a cover plate 300. A first magnetic attraction structure 110 is provided on the back side of the shell 100. The back plate 200 includes a first plate 210 and a second plate 220 arranged sequentially in its width direction. At least two second magnetic attraction structures 211 are provided on the first plate 210. Multiple second magnetic attraction structures 211 are arranged sequentially in the width direction of the first plate 210. The second magnetic attraction structures 211 attract the first magnetic attraction structure 110, allowing the shell 100 to be mounted on the first plate 210. The first plate 210 and the second plate 220 are rotatably connected to adjust the angle between them. The cover plate 300 is movably connected to the side of the second plate 220 away from the first plate 210. The cover plate 300 can support the second plate 220 by folding.

[0044] Firstly, the user can fold the cover plate 300 to support the second plate 220. Since the second plate 220 is connected to the first plate 210 and the housing 100 is connected to the first plate 210, the cover plate 300 can be used to support the housing 100, so that the mobile terminal connected to the housing 100 can be placed on the table in an inclined position, freeing the user's hands.

[0045] Secondly, in this embodiment, the second plate 220 is rotatably connected to the first plate 210, so the angle between the second plate 220 and the first plate 210 can be adjusted. Since the housing 100 is connected to the first plate 210 and the cover plate 300 is supported by the second plate 220, adjusting the angle between the second plate 220 and the first plate 210 means adjusting the tilt angle of the mobile terminal. Therefore, the protective cover 1000 of this embodiment can meet the different tilt angle requirements of different users.

[0046] Thirdly, in this embodiment, there are two second magnetic structures 211 and multiple second magnetic structures 211 are arranged sequentially in the width direction of the first plate 210. Therefore, the first magnetic structure 110 can adjust the usage height of the mobile terminal by cooperating with different second magnetic structures 211 to meet the different usage height requirements of different users.

[0047] Therefore, the protective case 1000 provided in this embodiment can not only adjust the tilt angle of the mobile terminal when supporting it, but also adjust its height, resulting in an excellent user experience.

[0048] In some embodiments, the protective sleeve 1000 further includes a damping shaft 230, and the first plate 210 and the second plate 220 are connected by the damping shaft 230.

[0049] By implementing this embodiment, the first plate 210 can be suspended at any angle, achieving the technical effect of stepless adjustment, which can better meet the different needs of different users for tilt angle.

[0050] In some embodiments, the cover plate 300 includes a third plate 310, a fourth plate 320 and a fifth plate 330 arranged sequentially in its width direction. The third plate 310 is movably connected to the side of the second plate 220 away from the first plate 210, and the fourth plate 320 is movably connected to the third plate 310 and the fifth plate 330, so that the cover plate 300 can support the second plate 220 by folding.

[0051] Specifically, since the third plate 310 is movably connected to the side of the second plate 220 away from the first plate 210, the cover plate 300 can be folded to the back of the housing 100. Since the fourth plate 320 is movably connected to the third plate 310 and the fifth plate 330, the fourth plate 320 can be folded relative to the third plate 310, and the fifth plate 330 can be folded relative to the fourth plate 320. This arrangement allows the fifth plate 330 to be folded to abut against the side of the second plate 220 away from the housing 100. At this time, the second plate 220 and the cover plate 300 can form a triangular support structure, thereby providing support for the housing 100 and the mobile terminal.

[0052] refer to Figure 6 , Figure 10 In a specific embodiment, the second plate 220 is provided with a third magnetic structure 221, and the fifth plate 330 is provided with a fourth magnetic structure 331. When the flip cover is folded to support the second plate 220, the third magnetic structure 221 and the fourth magnetic structure 331 attract each other.

[0053] By implementing this embodiment, when the cover plate 300 is folded to form a triangular support structure with the second plate 220, the third magnetic attraction structure 221 on the second plate 220 and the fourth magnetic attraction structure 331 on the fifth plate 330 can be used to increase the connection stability between the second plate 220 and the fifth plate 330, ensuring that the cover plate 300 can stably support the fifth plate 330.

[0054] Furthermore, without the third magnetic structure 221 and the fourth magnetic structure 331, the triangular support structure will disintegrate when the user picks up the mobile terminal. If the user simply wants to adjust the position of the mobile terminal, they may have to fold the cover 300 again, resulting in a poor user experience. In this example, when the user picks up the mobile terminal, the fifth plate 330 and the second plate 220 can also be attracted together by the fourth magnetic structure 331 and the third magnetic structure 221, preventing the support structure from disintegrating. Therefore, it is not necessary to fold the cover 300 again, resulting in a better user experience.

[0055] In some embodiments, the first magnetic structure 110 and the second magnetic structure 211 are both bar magnets that extend along the length direction of the back plate 200.

[0056] Specifically, the bar magnet has a relatively large length and a relatively small width. Therefore, when multiple first magnetic attraction structures 110 are provided, using a bar magnet can ensure sufficient attraction force while facilitating the sequential arrangement of multiple first magnetic attraction structures 110 in the width direction of the housing 100. Similarly, when multiple second magnetic attraction structures 211 are provided, using a bar magnet can ensure sufficient attraction force while facilitating the sequential arrangement of multiple second magnetic attraction structures 211 in the width direction of the first plate 210.

[0057] In some embodiments, both the first magnetic attraction structure 110 and the second magnetic attraction structure 211 are arc-shaped magnets or ring magnets.

[0058] refer to Figure 1 and Figure 6 In some embodiments, the back plate 200 is provided with a first connecting structure 240, and the protective sleeve 1000 also includes a flexible strip 400. One end of the flexible strip 400 is connected to the cover plate 300, and the other end is provided with a second connecting structure 410. When the cover plate 300 is flipped to cover the housing 100, the first connecting structure 240 can be used for detachable connection with the second connecting structure 410.

[0059] Specifically, when the user does not need to use the mobile terminal, the cover 300 can be flipped over to cover the housing 100 to provide sufficient protection for the mobile terminal. By implementing this embodiment, when the cover 300 is flipped over to cover the housing 100, the first connecting structure 240 can be connected to the second connecting structure 410. At this time, the cover 300 and the housing 100 will be locked, which can effectively prevent the cover 300 from being flipped open by external force, resulting in the inability to provide sufficient protection for the mobile terminal.

[0060] It is worth mentioning that there are many specific implementations of the first connecting structure 240 and the second connecting structure 410. This embodiment does not limit them, as long as the other end of the flexible strip 400 can be detachably connected to the back plate 200. Two specific embodiments are listed below for illustration.

[0061] In one specific embodiment, the first connecting structure 240 is one of the hook side and the loop side of the hook and loop fastener, and the second connecting structure 410 is the other of the hook side and the loop side of the hook and loop fastener. With this configuration, as long as the first connecting structure 240 is placed on the second connecting structure 410, the first connecting structure 240 and the second connecting structure 410 can be connected, thereby locking the cover plate 300; as long as a force that can separate the second connecting structure 410 from the first connecting structure 240 is applied to the second connecting structure 410, the second connecting structure 410 can be disconnected from the first connecting structure 240, thereby allowing the cover plate 300 to be opened.

[0062] refer to Figure 1 and Figure 6 In another specific embodiment, the first connecting structure 240 is a fifth magnetic attraction structure, and the second connecting structure 410 is a sixth magnetic attraction structure that can attract the fifth magnetic attraction structure. With this configuration, as long as the sixth magnetic attraction structure is placed next to the fifth magnetic attraction structure, the fifth magnetic attraction structure can attract the sixth magnetic attraction structure, thereby locking the cover plate 300. Only by applying a force to the sixth magnetic attraction structure that can separate it from the fifth magnetic attraction structure, the fifth magnetic attraction structure can be disengaged from the sixth magnetic attraction structure, thereby allowing the cover plate 300 to be opened.

[0063] refer to Figure 9 and Figure 10 In some embodiments, the sixth magnetic structure protrudes in the thickness direction of the flexible strip 400, and the sixth magnetic structure is spaced apart from the end face 420 of the other end of the flexible strip 400, so that a gap space 500 is formed on the side of the sixth magnetic structure near the end face 420.

[0064] Specifically, if the sixth magnetic structure is flush with the end face 420 of the other end of the flexible strip 400, there will be no gap space 500. This would make it difficult for the user to pry open the sixth magnetic structure, resulting in a poor user experience. The formation of the gap space 500 makes it easier for the user to pry open the sixth magnetic structure, resulting in a better user experience.

[0065] refer to Figure 6 and Figure 10 In some embodiments, the first connecting structure 240 is disposed on the side of the first plate 210 away from the second plate 220, and the flexible strip 400 is connected to the side of the cover plate 300 away from the second plate 220.

[0066] By implementing this embodiment, the flexible strip 400 can be made shorter. Making the flexible strip 400 shorter not only saves the material used in the protective cover 1000 and improves the aesthetics of the protective cover 1000, but also simplifies the user's operation.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
