During driving, drivers often use mobile terminals for navigation, etc. In order to facilitate the viewing of mobile terminals, a vehicle-mounted support is needed to support the mobile phone in the passenger compartment.

[0005] Nowadays, mobile phones have wireless charging function, and a ring-shaped magnet structure is used in the mobile phone. The magnetic structure of the vehicle-mounted support also has a ring-shaped magnet structure. Through the magnetic attraction effect between the magnet structure of the mobile phone and the magnet structure of the vehicle-mounted support, the mobile phone is fixed on the vehicle-mounted support, so that the mobile phone is fixed and supported by the vehicle-mounted support.

[0006] However, when the mobile phone is taken off the vehicle-mounted support, the magnetic attraction between the magnetic structure and the mobile phone does not need to be very strong, and excessive magnetic attraction will make the process of taking off the mobile phone troublesome, usually requiring both hands to operate, especially for the driver who is driving, which increases the driving risk.

[0031] Please refer to Figures 1 to 3 The magnetic attraction structure 300 provided by the embodiments of the present application and the vehicle-mounted support having the same. The magnetic attraction structure 300 is detachably connected to a mobile phone by using magnetic attraction effect. It can be understood that the mobile phone has a magnet inside, or the mobile phone has a structural member capable of magnetically attracting the magnet, such as metal iron, so as to generate magnetic attraction effect with the magnetic attraction structure 300. In the embodiments, the mobile phone is provided with a plurality of magnets arranged in a ring shape. In other embodiments, the mobile phone can be replaced by other electronic products, which is not limited here and can be selected according to actual conditions.

[0032] Please refer to Figures 1 to 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 shell 101 with a receiving cavity 105 and a plurality of first magnetic strips 103 arranged in the receiving cavity 105. The first shell 101 is provided with an opening 106 communicating with the receiving cavity 105, and each of the first magnetic strips 103 is annular and arranged in the cavity bottom of the receiving cavity 105 in sequence with intervals, i.e. each of the first magnetic strips 103 is arranged in a circle around the center position of the cavity bottom of the receiving cavity 105 and is adapted to the arrangement of the magnet on the mobile phone; the first shell 101 is further provided with a magnetic attraction surface 110 arranged backward to the opening 106. The mobile phone is placed on the magnetic attraction surface 110, and the magnetic pole arrangement of the magnet in the mobile phone is adapted to the magnetic pole arrangement of the first magnetic strips 103, so that the mobile phone can be magnetically attracted to each of the first magnetic strips 103 and is detachably fixed on the first shell 101. It can be understood that the first magnetic strips 103 can generate a magnetic field and can be a static magnet, a permanent magnet or a permanent magnet.

[0033] The second magnetic attraction assembly 200 comprises a second shell 201 arranged at the opening 106 and a plurality of second magnetic strips 203 connected to the second shell 201, and the second shell 201 is movably arranged at the opening 106. Each of the second magnetic strips 203 is annular and arranged in sequence with intervals, and the magnetic pole arrangement of the first magnetic strips 103 and the second magnetic strips 203 is opposite; the projection of any second magnetic strip 203 on the cavity bottom of the receiving cavity 105 is located between two adjacent first magnetic strips 103. It can be understood that the second magnetic strips 203 can generate a magnetic field and can be a static magnet, a permanent magnet or a permanent magnet.

[0034] Please refer to Figures 3 to 5The first shell 101 has a first position state and a second position state; when the first shell 101 is in the first position state, the mobile phone is placed on the magnetic surface 110, and the first shell 101 moves away from the second shell 201, that is, the second shell 201 moves outward from the accommodating cavity 105 relative to the first shell 101 by a predetermined distance, so that the first magnetic strips 103 and the second magnetic strips 203 are arranged in a spaced manner along the moving direction, so that the second magnetic strips 203 do not interfere with the magnetic attraction connection between the first magnetic strips 103 and the mobile phone, and each first magnetic strip 103 can maintain sufficient magnetic attraction force on the mobile phone; when the first shell 101 is in the second position state, that is, the first shell 101 moves towards the second shell 201, that is, the first shell 101 moves into the accommodating cavity 105 by a predetermined distance, so that each first magnetic strip 103 and each second magnetic strip 203 are spliced into a magnetic attraction ring 500, and the first magnetic strips 103 and the second magnetic strips 203 are arranged alternately. It can be understood that the magnetic field of each second magnetic strip 203 interferes with and disrupts the magnetic field of each first magnetic strip 103, thereby reducing the overall magnetic field strength of the magnetic attraction ring 500, thereby weakening the magnetic attraction force between the mobile phone and each first magnetic strip 103, facilitating the removal of the mobile phone from the magnetic surface 110. It can also be understood that the force between the first magnetic strip 103 and the mobile phone is an attractive force, while the force between the second magnetic strip 203 and the mobile phone is a repulsive force, thereby reducing the magnetic attraction force between the mobile phone and the first magnetic strip 103.

[0035] Please refer to Figures 1 to 3 The magnetic attraction structure 300 provided by the embodiment includes a first magnetic attraction assembly 100 and a second magnetic attraction assembly 200. When the first shell 101 is in the first position state, each first magnetic strip 103 is magnetically connected to the mobile phone located on the magnetic surface 110. When the first shell 101 is switched to the second position state, each first magnetic strip 103 and each second magnetic strip 203 are spliced and arranged alternately, thereby weakening the magnetic attraction force between the mobile phone and each first magnetic strip 103, facilitating the removal of the mobile phone from the magnetic surface 110, and improving the convenience and safety of use of the magnetic attraction structure 300.

[0036] Optionally, when the first shell 101 is in the second position state, each first magnetic strip 103 and each second magnetic strip 203 are located in the same plane.

In the embodiment, the shape of the magnetic attraction ring 500 is a circle, and the shapes of the first magnetic strips 103 and the second magnetic strips 203 are both arc-shaped. In other embodiments, the shape of the magnetic attraction ring 500 can also be a polygon or an ellipse, which is not limited here and can be selected according to actual conditions.

[0041] It can be understood that each first magnetic strip 103 is arranged in sequence in a circle and is spaced apart, each second magnetic strip 203 is arranged in sequence in a circle and is spaced apart, and the centers of the two circles coincide.

It can be understood that when the first shell 101 is in the first position state, the elastic member 400 is in a natural elongation state, when it is necessary to remove the mobile phone, the operator can hold the mobile phone and press the first shell 101 towards the second shell 201 until each second magnetic strip 203 is spliced in place with each first magnetic strip 103, and the elastic member 400 is in a compressed state, at which point the mobile phone can be conveniently removed from the magnetic attraction surface 110, and then the elastic member 400 returns to its original state and drives the first shell 101 to switch to the first position state.

[0044] Referring to Figures 2 to 4 In some embodiments, the elastic member 400 is a tube spring, and each first magnetic strip 103 or each second magnetic strip 203 is arranged along the circumference of the elastic member 400, so that the mobile phone is stressed smoothly when it is taken out or put in, and the tube spring smoothly drives the first shell 101 to switch to the first position state.

[0046] It can be understood that the principle of the press switch is similar to that of a self-locking switch or a press-type ballpoint pen, which will not be described here. When the press switch is in the unlocked state, the first shell 101 is away from the second shell 201, and the first shell 101 is in the first position state. Pressing the first shell 101 towards the second shell 201 makes the press switch in the locked state, and the press switch can keep the first shell 101 in the second position state, thereby facilitating the user to remove the mobile phone. Pressing the first shell 101 again makes the press switch in the unlocked state, and the elastic member 400 drives the first shell 101 to reset to the first position state.
