In other embodiments, the first magnetic element 11 is disposed at a midpoint position of an end edge of the foldable electronic device 100, the second end folding portion 41 is disposed corresponding to the first magnetic element 11 and is provided with the second magnetic element 12, and the second magnetic element 12 on the second end folding portion 41 and the first magnetic element 11 of the foldable electronic device 100 are fixed by being attracted to each other, so that the opposite end of the protective cover 200 hooks the housing of the foldable electronic device 100 through the hook 60 and is fixed by being attracted to each other through the magnetic elements fixed by being attracted to each other, thereby ensuring that the protective cover 200 stably covers the display screen 30 of the foldable electronic device 100.

The length of the hook 60 is equal to or less than the length of the short side of the foldable electronic device 100, the shape of the hook 60 includes, but is not limited to, an arc shape and a semicircular shape, and the material of the hook 60 includes, but is not limited to, metal and plastic. Preferably, the length of the hook 60 is equal to the length of the short side of the foldable electronic device 100, and the shape of the short side of the foldable electronic device 100 is the same as the arc shape of the casing of the foldable electronic device 100, so that the hook 60 can stably hook the casing of the foldable electronic device 100 and has better overall aesthetic property, and furthermore, the hook 60 is made of a plastic material with softer texture, so that the hook 60 can be prevented from scratching the casing of the foldable electronic device 100 and can reduce the overall weight of the protective sleeve 200.

The short side length of the foldable electronic device 100 in the present invention is a length parallel to the folding axis direction of the foldable electronic device 100.

Further, one of the folding portions 40 of the protective cover 200 is provided with a third magnetic element 13 corresponding to the hall sensor 20 of the foldable electronic device 100, and when the protective cover 200 covers the display screen 30 of the foldable electronic device 100, magnetic lines of force of the third magnetic element 13 pass through the hall sensor 20.

Specifically, as shown in fig. 1, in some embodiments, the folded portion 44 of the protective cover 200 is provided with a third magnetic element 13, and the third magnetic element 13 corresponds to the hall sensor 20 of the foldable electronic device 100. When the protective cover 200 covers the display screen 30 of the foldable electronic device 100, the magnetic lines of force of the third magnetic element 13 pass through the hall sensor 20. Specifically, in the present embodiment, the hall sensor 20 is disposed in a region of the foldable electronic device 100 corresponding to the folding portion 44, and the third magnetic element 13 is disposed in the folding portion 44.

In other embodiments, the hall sensor 20 may be reasonably disposed in the area of the foldable electronic device 100 corresponding to the other folding portion 40, and the third magnetic element 13 corresponding to the hall sensor 20 is disposed in the other folding portion 40 of the protective cover 20. For example, the hall sensor 20 is disposed in a region of the foldable electronic device 100 corresponding to the first end folding portion 45, and the first end folding portion 45 is disposed corresponding to the hall sensor 20 and the third magnetic element 13.

In other embodiments, the number of the third magnetic elements 13 corresponding to the hall sensor 20 may be multiple, when the protective cover 200 covers the display screen 30 of the foldable electronic device 100, projections of the multiple third magnetic elements 13 on the display screen 30 are located around the hall sensor 20, and when the protective cover 200 moves due to an external force, at least one magnetic line of force of the third magnetic element 13 passes through the hall sensor 20.

It is understood that, in order to ensure the bending performance of the flexible folding portion 43, the third magnetic element 13 cannot be disposed in the area of the flexible folding portion 43, and accordingly, the hall sensor 20 cannot be disposed in the bending area 50 of the foldable electronic device; in addition, the magnetic lines of force of the first magnetic element 11 disposed on the foldable electronic device 100 may not pass through the hall sensor 20, i.e., the hall sensor 20 is not affected by the first magnetic element 11 in the foldable electronic device 100.

Wherein, the folding portion 44 of the protective cover 200 is provided with a third magnetic element 13 corresponding to the hall sensor 20 on the foldable electronic device 100, which is not described herein again.

Thus, in the embodiment shown in fig. 13, the protective cover 200 can protect the display 30 of the foldable electronic device 100 regardless of whether the foldable electronic device is in the unfolded state or the folded state; in addition, the user can also turn over the protective case 200 to realize the screen locking and waking functions of the foldable electronic device 100; it is understood that the protective cover 200 is not provided with hooks 60 and cannot be used to support the foldable electronic device 100.

In the above embodiments, the protective cover 200 has been described as a preferred embodiment including five folds 40, it is understood that in other embodiments, the protective cover 200 may include other numbers of folds 40, and the protective cover 200 has at least some of the functions of the preferred embodiment. For example, in some embodiments, the protective cover 200 includes seven folding portions 40 arranged along the length direction thereof and a hook 60 is disposed at one end, the support frame formed by folding the protective cover 200 is slightly smaller but can still realize the support function, and the protective cover 200 has all the functions and features of the above embodiments, which are not described herein again; in some embodiments, the protective sheath 200 includes more than seven folds 40, and although the protective sheath 200 can be folded to form a support frame, the support frame will be too small to support firmly, making it difficult to achieve the support function; similarly, when the protective cover 200 does not need to have a supporting function, the protective cover 200 may also include three folding portions 40, and only the portion corresponding to the bending region 50 of the foldable electronic device 100 needs to be a flexible folding portion, and the folding portions 40 at the two ends are correspondingly provided with magnetic elements, so as to ensure that other functions, such as a screen locking function, a wake-up function, and a protection function for the display screen 30 of the foldable electronic device 100, can be implemented.

The above is an implementation manner of the embodiments of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principles of the embodiments of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
