[0027] Please refer to Figures 1 to 5 , the present invention provides a folding protective housing, including a first housing 1 and a second housing 2 that can relatively perform a flipping motion. The second housing 2 includes a connecting housing 21 and a frame 22 that are slidably connected. One side of the connecting housing 21 is fixedly connected to the first housing 1, and two sliding assemblies 3 are respectively provided at both ends of the connecting housing 21, and the two sides away from the first housing 1 are respectively connected to the frame 22 through the two sliding assemblies 3, so that the connecting housing 21 and the frame 22 can relatively approach or move away from each other.

[0028] In this embodiment, the foldable protective case includes a first housing 1 and a second housing 2 which are connected to each other, and the first housing 1 and the second housing 2 can perform a flipping movement relative to each other, so that the first housing 1 and the second housing 2 can approach or move away from each other relatively. A foldable electronic device is connected inside the first housing 1 and the second housing 2. Among them, under the external force of the user, the first housing 1 and the second housing 2 can be folded or opened relative to each other. When the first housing 1 and the second housing 2 approach each other relatively, that is, the two are folded, so that the foldable electronic device can be folded. When the first housing 1 and the second housing 2 move away from each other relatively, that is, the two are opened, so that the foldable electronic device is also unfolded. Among them, the foldable electronic device in the embodiment of the present application is a triple-fold screen mobile phone 5, and the foldable electronic device in the following text refers to the triple-fold screen mobile phone 5 in this embodiment.

[0029] Specifically, when the foldable protective case is assembled on the triple-fold screen mobile phone 5, when the triple-fold screen mobile phone 5 is opened, the first housing 1 and the second housing 2 can be opened synchronously following the opened triple-fold screen mobile phone 5. When the triple-fold screen mobile phone 5 is folded, the first housing 1 and the second housing 2 can be folded and connected following the triple-fold screen mobile phone 5, so that the foldable protective case can adapt to the triple-fold screen mobile phone 5 while protecting the triple-fold screen mobile phone, that is, the first housing 1 and the second housing 2 can change according to the folded or unfolded state of the triple-fold screen mobile phone 5 while protecting the triple-fold screen mobile phone 5.

[0030] In this embodiment, the second housing 2 includes a connecting shell 21 and a frame body 22 which are connected to each other. One side of the connecting shell 21 is connected to the first housing 1, and a sliding assembly 3 is respectively arranged at the upper and lower ends of the connecting shell 21. The side of the connecting shell 21 away from the first housing 1 is connected to the frame body 22 through two sliding assemblies 3 respectively, so that the frame body 22 can approach or move away from the connecting shell 21 through the sliding assembly 3, and further make the second housing 2 present a state of unfolding or closing. Among them, the structures of the two sliding assemblies 3 are exactly the same.

[0031] Specifically, the triple-fold screen mobile phone 5 includes three foldable display screens, namely the first display screen, the second display screen, and the third display screen. When the first display screen, the second display screen, and the third display screen are folded together, the first housing 1 is assembled on the first display screen and the second display screen with a camera on the back, and the second housing 2 is used to wrap the third display screen disposed on the second display screen. Among them, when the triple-fold screen mobile phone 5 is in the folded state, it is disposed in the relatively combined first housing 1 and second housing 2. When the first housing 1 and the second housing 2 are relatively opened or combined, the first display screen and the second display screen and the third display screen folded together are relatively opened or combined, that is, the second display screen and the first display screen are relatively moved away from or close to each other. That is, when the first housing 1 and the second housing 2 are opened, the two screens for displaying content are the first display screen and the second display screen. Among them, when the first housing 1 and the second housing 2 are relatively unfolded, it is necessary to forcefully take out the second display screen assembled in the first housing 1. When it is necessary to open the second display screen and the third display screen folded together, it is necessary to remove the second housing 2 from the second display screen and the third display screen folded together, and then relatively unfold the second display screen and the third display screen to form a state where all three display screens are fully opened, and extend the second housing 2, that is, slide the connecting shell 21 and the frame 22 away from each other through the sliding assembly 3, so that the second housing 2 can be extended. After the second housing 2 is extended, the frame 22 of the second housing 2 is sleeved on the border of the third display screen, so as to play a protective role for the third display screen. Among them, after the three display screens are fully unfolded, the second display screen is in the middle of the first display screen and the third display screen. The first housing 1 is always assembled on the first display screen and the second display screen with a camera, and the second housing 2 is sleeved on the third display screen, so that the retractable protective shell can play a protective role for the four corners of the unfolded triple-fold screen mobile phone.

[0032] Further, the sliding assembly 3 includes a first sliding member 31 and a second sliding member 32 that can slide relative to each other. One end of the first sliding member 31 is fixedly connected to one end of the connecting shell 21, and one end of the second sliding member 32 is slidably connected to the frame 22 through a connecting member 33, so that the second sliding member 32 can approach or move away from the frame 22. The second sliding member 32 is also slidably disposed on the first sliding member 31, so that the second sliding member 32 drives the frame 22 to move away from or close to the connecting shell 21.

[0033] In this embodiment, the sliding assembly 3 includes a first sliding member 31 and a second sliding member 32. The first sliding member 31 and the second sliding member 32 are slidably connected, and the second sliding member 32 can slide relatively away from or close to the first sliding member 31. One side of the first sliding member 31 is fixedly connected to the connecting shell 21, and the other side is slidably connected to the second sliding member 32, so that the second sliding member 32 can slide on the first sliding member 31, and thus can relatively approach or move away from the connecting shell 21.

[0034] One end of the second sliding member 32 is close to the first housing 1 connected to the connection housing 21, and the other end is used to connect to the frame 22. The second sliding member 32 is slidably connected to the frame 22 through a connecting member 33, so that the second sliding member 32 can move closer to or away from the frame 22. When the second sliding member 32 slides on the first sliding member 31, the second sliding member 32 drives the frame 22 through the connecting member 33 to move closer to or away from the connection housing 21 relatively.

[0035] Wherein, the connection housing 21 and the frame 22 can be separated by a certain distance through the sliding connection of the first sliding member 31 and the second sliding member 32, and the sliding connection between the frame 22 and the second sliding member 32 can also be separated by a certain distance. The distances separated by the two can make the distance between the connection housing 21 and the frame 22 larger, so that a display screen can be assembled when the second housing 2 is closed, and two display screens can be assembled when it is opened.

[0036] Further, a first groove 311 is formed on the first sliding member 31. A protruding member 321 is arranged on one side of the second sliding member 32 close to the first sliding member 31. The protruding member 321 is slidably arranged in the first groove 311, so that the second sliding member 32 can drive the frame 22 to move closer to or away from the connection housing 21.

Wherein, the size of the protruding member 321 is adapted to the size of the first groove 311, so that the protruding member 321 can slide left and right in the first groove 311.

[0038] Specifically, when the second sliding member 32 moves away from the first sliding member 31 through the protruding member 321, that is, the second sliding member 32 moves away from the connection housing 21, which means the second sliding member 32 drives the frame 22 to move away from the connection housing 21, and the second housing 2 is in the unfolded state; when the second sliding member 32 moves closer to the first sliding member 32 through the protruding member 321, that is, the second sliding member 32 moves closer to the connection housing 21, which means the second sliding member 32 drives the frame 22 to move closer to the connection housing 21, and the second housing 2 is in the closed state.

[0039] Further, a first fixing member 312 is provided at one end of the first groove 311 away from the frame 22. A first elastic member 313 is connected to the first fixing member 312. One end of the first elastic member 313 away from the first fixing member 312 is connected to the protruding member 321. When the first elastic member 313 returns to its original state, it can drive the second sliding member 32 to drive the frame 22 to move towards the connecting shell 21.

[0041] Specifically, when the second sliding member 32 is under the action of an external force, the first elastic member 313 connected to the protruding member 321 is stretched, and the second sliding member 32 drives the frame 22 to move away from the connecting shell 21, so that the frame 22 and the connecting shell 21 are relatively separated. When the external force on the second sliding member 32 is removed, the first elastic member 313 connected to the protruding member 321 returns to its original state, and the first elastic member 313 will drive the frame 22 to move towards the connecting shell 21.

[0042] Further, a second groove 322 is also provided on the second sliding member 32. The connecting member 33 is slidably disposed in the second groove 322 and is fixedly connected to the frame 22, so that the frame 22 can approach or move away from the connecting shell 21 through the second sliding member 32.

[0043] In this embodiment, a second groove 322 is also provided on the second sliding member 32. The connecting member 33 is slidably disposed in the second groove 322.

[0044] Specifically, the housing 22 is slidably connected to the second sliding member 32 through the connecting member 33, so that the housing 22 can be relatively close to or away from the second sliding member 32 through the connecting member 33. When the housing 22 approaches the second sliding member 32 through the connecting member 33, the housing 22 is also relatively close to the connection shell 21. When the housing 22 moves away from the second sliding member 32 through the connecting member 33, the housing 22 is also relatively away from the connection shell 21. That is, when the housing 22 is away from the second sliding member 32 and the connection shell 21, the second housing 2 is in the unfolded state. When the housing 22 approaches the second sliding member 32 and the connection shell 21, the second housing 2 is in the closed state.

[0045] Further, a second fixing member 323 is provided at one end of the second groove 322 away from the housing 22. A second elastic member 324 is connected to the second fixing member 323.
