[0024] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1-Figure 3 The utility model proposes a mobile phone magnetic suction cup, including a silicone back cover 1, a fixed shell 2, and a magnetic ring assembly 3. The silicone back cover 1 wraps the back and the outer peripheral side of the fixed shell 2 and is fixedly connected to the fixed shell 2. The back of the silicone back cover 1 is provided with a plurality of suction cups 11 for external fixation. The fixed shell 2 is a circular structure and is made of PC material (polycarbonate). The fixed shell 2 is provided with an annular groove 21 and a supporting boss 22. The supporting boss 22 is located at the center of the annular groove 21. The magnetic ring assembly 3 is accommodated in the annular groove 21 and is fixedly connected to the bottom wall of the annular groove 21. The upper surface of the supporting boss 22 is flush with the upper surface of the magnetic ring assembly 3.

[0026] In this embodiment, the utility model forms a product by combining three parts, namely, a silicone back cover 1, a fixed shell 2, and a magnetic ring assembly 3. In this way, the above three parts can be produced separately by different manufacturers or production workshops, and then quickly assembled through multiple assembly lines without the need for specific integrated production equipment. In this way, the production efficiency is improved and the production difficulty is reduced. During assembly, the magnetic ring assembly 3 is first fixed in the annular groove 21, and then the silicone back cover 1 is coated with adhesive and wrapped around the back and outer peripheral side of the fixed shell 2. In this way, when the silicone back cover 1 wraps around the fixed shell 2, it is directly fixed to the fixed shell 2. At this time, the overall assembly of the product is completed, and the assembly is convenient and fast.

[0027] When in use, the magnetic ring assembly 3 is used to magnetically attract the back of the mobile phone or the back of the magnetic area of ​​the mobile phone case, and the support boss 22 is in contact with the back surface of the mobile phone, which can increase the friction between the back of the mobile phone and the magnetic attraction, and prevent the mobile phone from slipping due to vibration. When it needs to be fixed to the outside, multiple suction cups 11 are used to adsorb and fix the external plane, which is convenient and practical.

[0028] To sum up, this mobile phone magnetic suction cup not only has the functions of magnetically fixing the mobile phone and being small and convenient, but can also be assembled into a product through multiple accessories. In this way, multiple assembly lines can be opened for rapid assembly, which reduces the difficulty of production and thus increases output.

[0029] In this embodiment, the magnetic ring assembly 3 includes a plurality of bar magnets 31 and an annular adhesive backing 32. The plurality of bar magnets 31 are connected end to end to form a ring and are adhered to the upper surface of the annular adhesive backing 32. The annular adhesive backing 32 is a strong adhesive backing with strong adhesion. The annular adhesive backing 32 has a certain thickness, which is equal to the height of the supporting boss 22 after superimposed with the thickness of the bar magnets 31. The lower surface of the annular adhesive backing 32 is adhered to the bottom wall of the annular groove 21. When the magnetic ring assembly 3 is produced, the magnetic ring assembly 3 can be assembled separately by an assembly line. After the plurality of bar magnets 31 are arranged in a ring through an annular mold, the upper surface of the annular adhesive backing 32 is attached to the bottom surface of the bar magnet 31. The lower surface of the annular adhesive backing 32 is attached with anti-sticking paper. Before the magnetic ring assembly 3 is installed in the annular groove 21 on the fixed shell 2, the anti-sticking paper is torn off and attached and fixed.

[0030] In this embodiment, the upper surface of the support boss 22 is provided with an anti-skid layer 221 for increasing friction. The anti-skid layer 221 can be an anti-skid pattern produced when the support boss 22 is produced, or it can be applied and adhered by an anti-skid coating. When the back of the mobile phone is magnetically attracted to the magnetic ring assembly 3, the anti-skid layer 221 will increase the friction with the back of the mobile phone.

[0031] In this embodiment, a nesting groove 12 is provided on the silicone back cover 1, and the fixed shell 2 is accommodated in the nesting groove 12. When assembling the silicone back cover 1 and the fixed shell 2, adhesive is applied to the nesting groove 12, and then the fixed shell 2 is placed in the nesting groove 12 and bonded to complete the fixed connection.

[0032] In this embodiment, the plurality of suction cups 11 and the silicone back cover 1 form an integrated structure, which can improve the stability of the suction cups 11 and reduce the production process.

[0033] In this embodiment, a plurality of suction cups 11 are evenly distributed circumferentially on the back of the silicone back cover 1 to form a multi-ring shape and fill the back area of ​​the silicone back cover 1. Such an arrangement enables the back of the silicone back cover 1 to have enough suction cups 11 for external adsorption and fixation to improve the external fixing force.

[0034] In this embodiment, a hanging ear plate 13 is provided on one side of the silicone back cover 1 for easy external fixation. The function of the hanging ear plate 13 is to facilitate the user to hang and place the utility model externally when the utility model is not in use.

[0035] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
