The magnetic attraction structure 300 is detachably connected with a mobile phone by a magnetic attraction effect. It is understandable that, an interior of the mobile phone is provided with a magnet, or the interior of the mobile phone is provided with a structural member capable of magnetically attracting the magnet, such as metallic iron, so that the magnetic attraction effect is capable of being generated with the magnetic attraction structure 300. In the embodiment, the interior of the mobile phone is provided with the magnet, a plurality of magnets are provided, and the magnets are annularly arranged. In other embodiments, the mobile phone may also be replaced with other electronic products, which is not limited herein and may be selected according to actual situations.

[0031] With reference to FIG. 1 to FIG. 3, the magnetic attraction structure 300 comprises a first magnetic attraction assembly 100 and a second magnetic attraction assembly 200. The first magnetic attraction assembly 100 comprises a first housing 101 provided with an accommodating cavity 105 and a plurality of first magnetic strips 103 arranged in the accommodating cavity 105. The first housing 101 is provided with an opening 106 communicated with the accommodating cavity 105, the first magnetic stripes 103 are annularly arranged at intervals in sequence at a cavity bottom of the accommodating cavity 105, which means that the first magnetic stripes 103 are circumferentially arranged around a center position of the cavity bottom of the accommodating cavity 105, and adapted to the magnets arranged on the mobile phone. The first housing 101 is further provided with a magnetic attraction surface 110, and the magnetic attraction surface 110 is arranged opposite to the opening 106. The mobile phone is placed on the magnetic attraction surface 110, and setting of a magnetic pole of the magnet in the mobile phone is adapted to setting of a magnetic pole of the first magnetic strip 103, so that the mobile phone is capable of being detachably fixed on the first housing 101 due to the magnetic attraction effect between the mobile phone and the first magnetic strips 103. It is understandable that, the first magnetic stripe 103 is capable of generating a magnetic field, and may be a static magnet, a constant magnet or a permanent magnet.

[0032] The second magnetic attraction assembly 200 comprises a second housing 201 located at the opening 106 and a plurality of second magnetic strips 203 connected with the second housing 201, and the second housing 201 is movably arranged at the opening 106. The second magnetic strips 203 are annularly arranged at intervals in sequence, and the magnetic pole of the first magnetic strip 103 and a magnetic pole of the second magnetic strip 203 are arranged oppositely. A projection of any second magnetic stripe 203 on the cavity bottom of the accommodating cavity 105 is located between two adjacent first magnetic stripes 103. It is understandable that, the second magnetic stripe 203 is capable of generating a magnetic field, and may be a static magnet, a constant magnet or a permanent magnet.

When the first housing 101 is in the first position state, the mobile phone is placed on the magnetic attraction surface 110, and the first housing 101 moves in a direction far away from the second housing 201, that is, the second housing 201 moves towards an exterior of the accommodating cavity 105 by a predetermined distance relative to the first housing 101, so that the first magnetic strips 103 and the second magnetic strips 203 are arranged at intervals along a moving direction, thus avoiding the second magnetic stripes 203 from interfering with magnetic attraction connection between the first magnetic stripes 103 and the mobile phone, and making the first magnetic stripes 103 maintain a sufficient magnetic attraction force to the mobile phone. When the first housing 101 is in the second position state, the first housing 101 moves in a direction close to the second housing 201, that is, the first housing 101 moves towards an interior of the accommodating cavity 105 by a predetermined distance, so that the first magnetic strips 103 and the second magnetic strips 203 are spliced into a magnetic attraction ring 500, and the first magnetic strips 103 and the second magnetic strips 203 are alternately arranged in sequence. It is understandable that, the magnetic fields of the second magnetic strips 203 interfere with the magnetic fields of the first magnetic strips 103 respectively, and disturb the magnetic fields of the first magnetic strips 103, so as to reduce an overall magnetic field strength of the magnetic attraction ring 500, thus reducing the magnetic attraction force between the mobile phone and the first magnetic strips 103, and being convenient to take down the mobile phone from the magnetic attraction surface 110. It is also understandable that, there is an attraction force between the first magnetic stripes 103 and the mobile phone, and there is a repulsion force between the second magnetic stripes 203 and the mobile phone, thus reducing the magnetic attraction force between the mobile phone and the first magnetic stripes 103.
