[0002] With the widespread use of smartphones, phone accessories have also become more common, such as phone cases. Phone cases provide cushioning and shock absorption, preventing the phone from breaking or cracking. Some phones have wireless charging capabilities. This is achieved by placing a receiving magnetic ring inside the phone corresponding to the receiving coil, and a transmitting magnetic ring inside the wireless charging pad corresponding to the transmitting coil. The mutual attraction between the receiving and transmitting magnetic rings allows the receiving coil inside the phone and the transmitting coil inside the wireless charging pad to automatically and accurately position themselves. For ease of use, phone cases usually have a ring for supporting or holding the phone. This ring is typically made of metal and is circular. The circular metal ring generates an induced current in the magnetic field of wireless charging, causing the ring to heat up during charging and reducing the efficiency of wireless charging.

Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0032] In related technologies, for ease of use, phone cases usually have a ring that can be used to support or hold the phone. The ring is usually made of metal and is circular. The circular metal ring will generate an induced current in the magnetic field of wireless charging, which will cause the ring to heat up during charging, reducing the efficiency of wireless charging.

[0033] Based on this, the bracket of this application has an opening, and the overall magnet assembly has a through slot, which helps to prevent the bracket from generating induced current in the magnetic field of wireless charging, solve the problem of ring heating, and improve wireless charging efficiency.

[0034] The following describes some embodiments of the magnetic phone case provided in this application with reference to the accompanying drawings.

[0035] Please see Figures 1 to 10 This application provides a magnetic phone case, including a housing 1, a magnet assembly, and other functional components as needed, which are described in detail below.

[0036] In this embodiment, the housing 1 has a bottom 101 and a side 102, which together form a receiving cavity for accommodating a mobile phone. The magnet assembly includes a bracket 2 and a magnet 4 fixed on the bracket 2. The bracket 2 is located on the back of the bottom 101 and has an arc-shaped structure with two opposing ends 201. A gap is left between the two ends 201 to form an opening 203 on the bracket 2. The two ends 201 are rotatably connected to the bottom 101 by connectors 3. The magnet 4 has at least one notch, one of which corresponds to the position of the opening 203 to form a through groove 6 between the two ends 201.

[0037] It is understood that the magnetic phone case provided in this application can be applied to both wirelessly charging and non-wirelessly charging phones. The case 1 can be made of plastic, silicone, or other materials. The case 1 has a bottom 101 and a side 102. The bottom 101 corresponds to the back cover of the phone, and the side 102 corresponds to the side frame of the phone. The case 1 can have multiple holes corresponding to the functional parts of the phone to create clearance. In this embodiment, the bottom 101 and side 102 can be an integral structure. The bracket 2 of this application has an arc-shaped structure, meaning the bracket 2 as a whole has an arc-shaped curved extension, such as a C-shape. The arc can be, but is not limited to, part of a circle or ellipse. The two ends 201 of the arc-shaped structure are the starting and ending points of the arc extension. A gap is left between the two ends 201, thus forming an opening 203. That is, the bracket 2 is not a complete ring. The two ends 201 are rotatably connected to the bottom 101 via connectors 3, such as... Figure 1 , Figure 10As shown, the bracket 2 can have an open state for supporting the mobile phone and a retracted state that fits against the bottom 101. When the bracket 2 is open to support the mobile phone, it has two fulcrums, resulting in better support and less wobbling. The magnet 4 in this application can generate a magnetic field and can be attracted to other magnets or metals. The magnet 4 has a notch, which can be a notch provided on a single magnet 4, or an open-ring magnet 4, in which case it has only one notch, or a notch formed by spacing between multiple magnets 4, in which case there can be one or more notches. The notch and opening 203 in this application correspond to each other, thus forming a through groove 6 between the two ends 201. The arc-shaped structure forms a bracket 2 with a hole structure, through which fingers can pass to pick up or hold the phone. When the bracket 2 is opened, the opening 203 allows the hole structure to directly connect to the back of the bottom 101. The opening 203 provides clearance for the fingers, preventing interference between the fingers and the hinged parts of the bracket 2 and the bottom 101 during the process of passing through or removing the hole structure, thereby improving the comfort of use. The bracket 2 in this application can be made of metal.

[0038] The magnetic phone case provided in the above embodiment has a bracket 2 with an arc-shaped structure. The arc-shaped structure has two opposing ends 201 with a gap between them to form an opening 203 on the bracket 2. The magnet 4 has at least one notch and is fixed to the bracket 2. One of the notches corresponds to the position of the opening 203 to form a through groove 6 between the two ends 201. The bracket 2 has an opening 203, and the overall magnet assembly has a through groove 6, which helps to prevent the bracket 2 from generating induced current in the magnetic field of wireless charging, solves the problem of ring overheating, and improves wireless charging efficiency.

[0039] In one embodiment, such as Figures 1-3 As shown, the arc-shaped structure is an arc shape. The lines connecting the two ends 201 to the center of the arc are the first line and the second line, respectively. The angle between the first line and the second line is greater than or equal to 180 degrees. When it is greater than or equal to 180 degrees, it is beneficial for the hole structure formed by the arc structure to allow fingers to pass through, and it is also beneficial for the bracket 2 to provide good support for the mobile phone. Specifically, in this embodiment, the first line and the second line can be the lines connecting the side of the end 201 near the opening to the center of the arc, specifically, the lines connecting the two endpoints of the inner circle of the arc structure to the center, or the lines connecting the two endpoints of the outer circle of the arc structure to the center. In some embodiments, the angle between the first line and the second line can be less than 180 degrees, which is sufficient to fix the magnet 4.

[0040] In one embodiment, such as Figure 2 , Figure 3As shown, end 201 has an extension 204 extending away from opening 203. The extension 204 protrudes from the outer side wall of bracket 2. End 201 has at least two first connecting posts 205, at least one of which is located on the extension 204. The connector 3 has a fixing hole, and the first connecting post 205 is fixed in the fixing hole to fix end 201 to connector 3. The extension 204 can increase the area of ​​end 201, which is beneficial to the connection of end 201 and increases the stability of the connection between end 201 and connector 3. In some embodiments, the extension 204 may be omitted as needed, and end 201 may be directly fixed to connector 3. In some embodiments, in order to facilitate the rotatable connection between end 201 and bottom 101, a cutting plane may be provided on the side of end 201 near connector 3, which is parallel to the rotation axis of bracket 2.

[0041] In one embodiment, such as Figure 2 , Figure 3 As shown, magnet 4 includes at least two sub-magnets, with a gap between each sub-magnet to form a notch between the opposite end faces of two adjacent sub-magnets, one of which corresponds to the position of opening 203; the bracket 2 is provided with a groove 202, and the sub-magnets are fixed in the groove 202. In some embodiments, magnet 4 can be formed by combining two sub-magnets. Combining at least two sub-magnets to form magnet 4 can reduce the concentration of the magnetic field and reduce the local intensity of the magnetic field, which is beneficial to reducing the interference of the mobile phone case on wireless charging. The shape and size of each sub-magnet can be the same or different. For example, when there are two, each sub-magnet can be an arc-shaped structure and symmetrically arranged on the bracket 2. In this application, the sub-magnets can be fixed in the groove 202 by means of, but not limited to, adhesive. The groove 202 on the bracket 2 can be provided on the side of the bracket 2 for abutting the bottom 101. The depth of the groove 202 can match the thickness of magnet 4 so that magnet 4 is flush with the surface of bracket 2.

[0042] In one embodiment, the distance between the two ends 201 is 8mm-25mm. It is understood that the distance between the two ends 201 is the distance between the two opposite sides of the two ends 201. In some embodiments, the distance between the two ends 201 may be less than 8mm or greater than 25mm.

[0043] In one embodiment, such as Figure 2 , Figure 9 As shown, the connector 3 is a hinge that rotatably connects end 201 to bottom 101 and fixes the bracket 2, which has been rotated to any angle. The connector 3 can stop the bracket 2 at any angle through frictional damping, and can also allow the bracket 2 to continue rotating or return to its original position after being subjected to a thrust.

[0044] In one embodiment, such as Figure 2, Figure 4 As shown, the back of the bottom 101 is provided with an arc-shaped groove 103, and the bracket 2 is located in the arc-shaped groove 103. The depth of the arc-shaped groove 103 matches the thickness of the bracket 2. Mounting portions are provided at both ends of the arc-shaped groove 103. The hinge includes a first hinge member 302 and a second hinge member 301 that are hinged to each other. The first hinge member 302 is fixedly connected to the end 201, and the second hinge member 301 is fixed in the mounting portion. The depth of the arc-shaped groove 103 matches the thickness of the bracket 2, thereby allowing the surface of the bracket 2 to be flush with the back of the bottom 101 after the bracket 2 is stored, which helps improve the flatness of the outer surface of the phone case. This embodiment does not limit the specific hinge structure between the first hinge member 302 and the second hinge member 301; any hinged connection is acceptable. In some embodiments, the end 201 may be provided with an assembly groove, and each of the first connecting posts 205 is provided in the assembly groove. The first hinge 302 is located in the assembly groove, and the first connecting posts 205 are fixed in the fixing holes on the first hinge 302, thereby fixing the first hinge 302 to the end 201. In some embodiments, the bracket 2 may also be directly attached to the back of the bottom 101, without the need for the arc-shaped groove 103.

[0045] In one embodiment, such as Figures 4-7 As shown, the mounting part includes a limiting block 104, with a gap between the limiting block 104 and the front of the bottom 101 to form a first space 106 for accommodating the second hinge member 301; the mounting part also includes a through clearance hole 105, which is located on the side of the limiting block 104 near the arc groove 103, for the first hinge member 302 to pass through during assembly, and the hinge portion between the first hinge member 302 and the second hinge member 301 is located in the clearance hole 105. The limiting block 104 can limit the second hinge 301. The setting of the clearance hole 105 facilitates the installation of the hinge. During installation, the first hinge 302 is inserted into the clearance hole 105 from the front of the bottom 101 and extends out from the back of the bottom 101. After extending, it can be connected and fixed to the end 201 of the bracket 2. The second hinge 301 abuts against the side of the limiting block near the front of the bottom 101. The hinge part between the first hinge 302 and the second hinge 301 is located in the clearance hole 105, thereby embedding the connector 3 in the bottom 101. This helps to prevent the connector 3 from protruding from the back of the bottom 101, which would affect the flatness of the outer surface of the phone case and make it difficult to place the phone stably. In addition, the second hinge 301 is located in the first space 106, which helps to prevent the second hinge 301 from protruding from the front of the bottom 101, which would affect the good fit between the phone case and the phone. In this application, the front side of the bottom 101 is the side that contacts the back cover of the mobile phone, and the back side is the side of the bottom 101 that is away from the front side and opposite to the front side. In this embodiment, the limiting block 104 can be an integral structure of the housing 1.

[0046] In one embodiment, such as Figure 2 , Figures 4-7 , Figure 9 As shown, the magnetic phone case also includes a fixing block 5. A second connecting post 501 is provided on one side of the fixing block 5. A gap is left between the limiting block 104 and the back of the bottom 101 to form a second space 107 to accommodate the fixing block 5. The fixing block 5 is located in the second space 107 and pressed against the limiting block 104. Both the limiting block 104 and the second hinge 301 are provided with fixing holes. The second connecting post 501 passes through the fixing holes of the limiting block 104 and the second hinge 301 in sequence, fixing the second hinge 301 in the mounting part. Fixing the second hinge 301 to the limiting block 104 by the fixing block 5 improves the appearance of the phone case. Furthermore, the fixing block 5 being located in the second space 107 helps prevent it from protruding from the other side of the bottom 101, improving the flatness of the outer surface of the phone case. To avoid interference between the fixing block 5 and the hinge joint, the side wall of the fixing block 5 near the clearance hole 105 can be flush with the side wall of the limiting block 104 near the clearance hole 105. In some embodiments, the second hinge member 301 of the hinge can also be directly fixed to the back of the bottom 101 without the need for an additional mounting part. In some embodiments, the connector 3 can also be other structures or components, for example, the bottom 101 and the end 201 can be rotatably connected directly. The connector 3 is a hole structure and a shaft structure, and the shaft structure fits into the hole structure to form a rotatable connection.

[0047] In one embodiment, such as Figures 6-8 As shown, a strip groove 108 is provided on the front of the bottom 101. The strip groove 108 extends from the mounting portion at one end of the arc-shaped groove 103 to the mounting portion at the other end. A cover plate 7 is fixed in the strip groove 108, and the cover plate 7 covers the second hinge member 301 and the clearance hole 105. The cover plate 7 fits in the strip groove 108, which helps to improve the appearance of the phone case. In order to make the front of the bottom 101 fit well with the back of the phone, the surface of the cover plate 7 can be flush with the front of the bottom 101. This embodiment does not specifically limit the specific fixing method of the cover plate 7, and adhesive fixing can be used.

[0048] In some embodiments, the bracket 2 may also be provided with a latching groove, which may be located at the top of the arc-shaped structure, thereby facilitating the application of force when opening the bracket 2. In some applications, the latching groove may also be located on the bottom 101. In some applications, when the bracket 2 is in the stored state, the magnet 4 can not only be used to attach to the wireless charging dock, but also, on some mobile phone holders 2 with magnetic attachment function, the magnetic attraction between the magnet 4 and the mobile phone holder 2 can prevent the phone from slipping.

[0049] In the magnetic phone case of the above embodiment, the bracket 2 has an arc-shaped structure with two opposing ends 201, with a gap between the two ends 201 to form an opening 203 on the bracket 2. The magnet 4 has at least one notch and is fixed inside the bracket 2. One of the notches corresponds to the position of the opening 203 to form a through groove 6 between the two ends 201. The bracket 2 has an opening 203, and the overall magnet assembly has a through groove 6, which helps to prevent the bracket 2 from generating induced current in the magnetic field of wireless charging, solves the problem of ring overheating, and improves wireless charging efficiency.
