[0042] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below in combination with the drawings.

[0043] As Figure 1 andFigure 2 As shown, the embodiment of the present application provides a folding shell, which comprises a first shell 1 and a second shell 2 connected by rotation, and a plurality of magnetic modules 3.

[0044] The plurality of magnetic modules 3 are arranged at the opening and closing end 11 of the first shell 1 and the second shell 2, and at least part of the magnetic modules 3 are located at the corners of the first shell 1 and the second shell 2. The magnetic modules 3 located at the first shell 1 can be attracted to the magnetic modules 3 located at the second shell 2.

[0045] The magnetic module 3 comprises a magnetic piece 31 and a magnetic isolation piece 32, and the magnetic isolation piece 32 is at least partially located at one side of the side of the magnetic piece 31 facing the first shell 1 or the second shell 2. That is, when the magnetic module 3 is located at the opening and closing end of the first shell 1, the magnetic isolation piece 32 is at least partially located at one side of the side of the magnetic piece 31 facing the first shell 1; when the magnetic module 3 is located at the opening and closing end of the second shell 2, the magnetic isolation piece 32 is at least partially located at one side of the side of the magnetic piece 31 facing the second shell 2.

[0046] Exemplarily, the folding shell is applied to folding electronic devices such as mobile phones, notebook computers, tablet computers, wearable devices, and vehicle-mounted devices, and the folding shell is a middle frame of the folding electronic devices.

[0047] Specifically, the first shell 1 and the second shell 2 are connected by rotation through a rotating shaft assembly, and the opening and closing end 11 is an end of the first shell 1 or the second shell 2 away from the rotating shaft assembly.

[0048] The folding shell has a folding state and an unfolding state, as Figure 1 shown, when the first shell 1 and the second shell 2 are stacked in the thickness direction, the folding shell is in the folding state; as Figure 2 shown, when the first shell 1 and the second shell 2 are distributed side by side and substantially located in the same plane, the folding shell is in the unfolding state.

[0049] As Figure 1 shown, the first shell 1 and the second shell 2 are substantially rectangular, and the magnetic modules 3 are arranged at the corners of the opening and closing end 11 of the first shell 1 and the second shell 2. When the folding shell is in the folding state, the positions of the magnetic modules 3 of the first shell 1 and the second shell 2 correspond to each other, so that the magnetic modules 3 of the first shell 1 and the second shell 2 can be better attracted, avoiding accidental unfolding of the folding shell.

[0050] Among them, the magnetic piece 31 is made of magnetic material, for example, the magnetic piece 31 is a permanent magnet, which has high energy density and stability, can maintain magnetism for a long time, and can ensure that the magnetic modules 3 of the first shell 1 and the second shell 2 have enough magnetic force for attraction.

[0051] The magnetic isolation member 32 is made of a magnetic isolation material, for example, the magnetic isolation member 32 includes one or more of a ferromagnetic material, a superconducting material, and a soft magnetic material.

[0052] The magnetic isolation member 32 has high magnetic permeability and low hysteresis, can effectively isolate the magnetic field, and by arranging at least part of the magnetic isolation member 32 on one side of the side surface of the magnetic member 31 facing the first housing 1 or the second housing 2, the magnetic field outside the magnetic member 31 at the four corners of the folding housing can be reduced, the attraction of the magnetic member 31 to external foreign matter is reduced, and meanwhile the magnetic attraction between the magnetic module 3 of the first housing 1 and the magnetic module 3 of the second housing 2 is not affected.

[0053] It should be noted that the side surface of the first housing 1 and the second housing 2 is a surface located between the front surface and the back surface, and the front surface and the back surface of the first housing 1 are away from each other along the thickness direction of the first housing 1, and the front surface and the back surface of the second housing 2 are away from each other along the thickness direction of the second housing 2.

[0054] In order to better illustrate the technical effects of the folding housing provided by the embodiments of the present application, the applicant has carried out simulation tests. Please refer to Figure 3 , Figure 3 (a) is a magnetic field line distribution diagram obtained by simulating the magnetic module 3 provided by the embodiments of the present application, Figure 3 (b) is a magnetic field line distribution diagram obtained by simulating the magnetic module without a magnetic isolation member in the prior art, Figure 3 the black solid line in the figures represents the magnetic field line, Figure 3 the rectangular light color block in (a) and Figure 3 (b) represents the magnetic member 31, Figure 3 the rectangular dark color block in (a) represents the magnetic isolation member 32. As can be seen in Figure 3 (a), the magnetic module 3 provided by the embodiments of the present application has a magnetic isolation member 32 arranged on one side of the side surface of the magnetic member 31, a part of the magnetic field line is bound in the magnetic isolation member 32, so that the leakage magnetic field outside the magnetic isolation member 32 is reduced, thereby effectively reducing the adsorption effect on foreign matter; in Figure 1 (b), the magnetic module in the prior art does not have a magnetic isolation member, and there is a leakage magnetic field around the magnetic member, which is easy to adsorb foreign matter around.

[0055] The folding housing provided by the embodiments of the present application can effectively reduce the magnetic field at the four corners of the folding housing and the folding electronic device by arranging the magnetic module 3 to include the magnetic member 31 and the magnetic isolation member 32, and arranging the magnetic isolation member 32 at least partially on one side of the side surface of the magnetic member 31 facing the first housing 1 or the second housing 2, thereby reducing the probability of adsorbing foreign matter at the four corners of the folding housing and the folding electronic device, and avoiding damage to the inner screen of the folding electronic device.

[0056] In a further embodiment, the magnetic isolation member 32 is a magnetic isolation member with a relative magnetic permeability greater than or equal to 1.5.

[0057] The relative magnetic permeability is the ratio of the magnetic permeability of a particular medium to the magnetic permeability of a vacuum, which is also known as the magnetic field constant, magnetic constant, free space magnetic permeability, or magnetic constant. The magnetic permeability of a vacuum is a physical constant, which refers to the magnetic permeability in a vacuum.

[0058] By setting the magnetic isolation member 32 as a magnetic isolation member with a relative magnetic permeability greater than or equal to 1.5, it ensures that the magnetic isolation member 32 has a high magnetic permeability and a strong magnetic isolation effect, thereby effectively reducing the magnetic field at the corners of the folding shell.

[0059] In an embodiment, the magnetic isolation member 32 is in the form of a sheet, and the thickness of the magnetic isolation member 32 is 0.01mm-2mm.

[0060] By setting the magnetic isolation member 32 as a sheet structure, it is convenient to attach the magnetic isolation member 32 to the side of the magnetic member 31, effectively reducing the magnetic field outside the corners of the folding shell and the folding electronic device, and avoiding the folding shell attracting foreign matter.

[0061] In a specific embodiment, the plurality of magnetic modules 3 includes a first magnetic module 301, a second magnetic module 302, a third magnetic module 303, and a fourth magnetic module 304.

[0062] As shown in Figure 2 or Figure 4 , there are four magnetic modules 3, and the four magnetic modules 3 are respectively located at the corner edges of the opening and closing end 11 of the first shell 1 and the second shell 2. The first magnetic module 301 and the third magnetic module 303 are matched in position and attract each other; the second magnetic module 302 and the fourth magnetic module 304 are matched in position and attract each other.

[0064] By setting four magnetic modules 3, it ensures that there is enough magnetic force between the first shell 1 and the second shell 2 to attract each other, preventing the folding shell from accidentally unfolding in the folded state.

[0065] In an optional embodiment, in the first magnetic module 301 and the third magnetic module 303, the magnetic member 31 comprises a plurality of magnets 311, the plurality of magnets 311 are sequentially arranged along the first direction X, and each magnet 311 has opposite magnetic polarity at both ends in the second direction Y, and the magnetic polarities of adjacent two magnets 311 are alternately arranged.

[0071] In this embodiment, by arranging the magnetic polarities of adjacent two magnets 311 alternately, a multi-pole magnet is formed, which has the advantages of uniform magnetic lines and good stability, and can improve the magnetic force attenuation phenomenon caused by the magnetic isolation member 32.

[0074] The magnetic shielding member 32 will cause a certain magnetic force decay.
