The use of words such as "example" or "for example" is intended to present relative concepts in a clear manner.

[0058] In addition, the "plurality" in the embodiments of the present application refers to two or more than two. In view of this, in the embodiments of the present application, "plurality" can also be understood as "at least two". "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one means including one, two or more, and there is no limit on which ones are included. For example, including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A, B and C can be included.

[0059] It should be noted that in this application, "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0060] The embodiment of the present application provides a mobile terminal protective shell, which can be a mobile phone protective shell or a handheld tablet computer protective shell. Of course, the mobile terminal protective shell can also be a protective shell of any other mobile terminal, which is not limited in the embodiment of the present application.

[0061] See also Figure 1 and Figure 2 The mobile terminal protective shell comprises a protective shell body 100, a display screen 200, a cover plate 300 and a magnetic attraction component 400. The protective shell body 100 is provided with a receiving cavity 11 for accommodating the mobile terminal. The display screen 200 is arranged on the protective shell body 100. The cover plate 300 is arranged on a side of the display screen 200 away from the receiving cavity 11. The magnetic attraction component 400 is embedded in the cover plate 300.

[0062] Then, the mobile terminal can be accommodated in the accommodating cavity 11, so that the mobile terminal protective shell can be installed on the mobile terminal. At this time, on the one hand, the mobile terminal protective shell can display images through the display screen 200, and on the other hand, the mobile terminal protective shell can be adsorbed and fixed with external devices through the magnetic component 400 to enrich the functions of the mobile terminal protective shell. On this basis, compared with the stacking of the magnetic component 400 and the cover plate 300, the embodiment of the present application can reduce the overall thickness formed by the magnetic component 400 and the cover plate 300 by embedding the magnetic component 400 in the cover plate 300, thereby making the overall thickness of the mobile terminal protective shell smaller, thereby improving the user experience.

[0063] It should be noted that in the embodiment of the present application, the magnetic component 400 is embedded in the cover plate 300. The magnetic component 400 may be embedded in the cover plate 300 as a whole, or only partially embedded in the cover plate 300. The embodiment of the present application does not limit this.

[0064] The above is an overall description of the technical solution of the embodiment of the present application. Next, the technical solution of the embodiment of the present application is described with examples in combination with the matching structure of the cover plate 300 and the magnetic attraction component 400.

[0065] In some embodiments, the cover plate 300 may be provided with a first mounting groove 321 , and the magnetic component 400 is disposed in the first mounting groove 321 , so that the magnetic component 400 may be embedded in the cover plate 300 .

[0066] It should be noted that in the embodiment of the present application, the magnetic component 400 is arranged in the first mounting groove 321. The magnetic component 400 can be embedded in the first mounting groove 321 as a whole, or the magnetic component 400 can be only partially embedded in the first mounting groove 321. The embodiment of the present application does not limit this.

[0067] In some embodiments, the opening of the first mounting groove 321 is located on the side of the cover plate 300 facing the display screen 200. Therefore, it is possible to prevent the magnetic attraction component 400 from being exposed.

[0068] It is understandable that if the magnetic component 400 is exposed on the side of the cover plate 300 facing away from the display screen 200 (i.e., the outer surface of the cover plate 300), on the one hand, the exposed magnetic component 400 will not only cause the gap between the magnetic component 400 and the cover plate 300 to be exposed, but also cause the gap between the magnetic component 400 and the cover plate 300 to be easily deposited with dust and difficult to clean, thereby reducing the aesthetics of the mobile terminal protective shell; on the other hand, the exposed magnetic component 400 also has the risk of falling off. In contrast, the embodiment of the present application opens the notch of the first mounting groove 321 on the side of the cover plate 300 facing the display screen 200 (i.e., the inner side of the cover plate 300), so that the magnetic component 400 can be hidden on the inner side of the cover plate 300, so as to improve the aesthetics of the magnetic component 400 and the stability and reliability of the installation.

[0069] In some embodiments, at least one of the cover plate 300 and the display screen 200 is bonded and fixed to the magnetic component 400, thereby preventing the magnetic component 400 from shaking and hitting the display screen 200 during use, thereby improving the stability and service life of the mobile terminal protective case.

[0070] Exemplarily, the magnetic component 400 is glued and fixed to the cover plate 300. For example, the magnetic component 400 may be arranged in the first mounting groove 321, and glue may be provided between the magnetic component 400 and the groove wall of the first mounting groove 321 for bonding and fixing; or an adhesive layer (such as adhesive tape) may be provided on the side of the magnetic component 400 away from the display screen 200 to be bonded and fixed to the cover plate 300 through the adhesive layer, and this embodiment of the application is not limited to this.

[0071] In some embodiments, the mobile terminal protective case further includes a partition component 500 , which is disposed on a side of the magnetic component 400 facing the display screen 200 to separate the display screen 200 from the magnetic component 400 .

[0072] It can be understood that the partition component 500 may include a magnetic isolation component to prevent the magnetic attraction component 400 from causing magnetic interference to the display screen 200 and / or the mobile terminal in the accommodating cavity 11; the partition component 500 may also include an elastic buffer component to prevent the magnetic attraction element from hitting the display screen 200; the partition component 500 may also include a hard buffer component to prevent the magnetic attraction element from hitting the display screen 200, and the embodiments of the present application are not limited to this.

[0073] In some embodiments, at least one of the cover plate 300 and the magnetic component 400 may be connected and fixed to the partition component 500. For example, the partition component 500 may be bonded and fixed to the cover plate 300 and / or the magnetic component 400, which is not limited in the present embodiment.

[0074] Please continue to refer to Figure 3 and Figure 4In some embodiments, the cover plate 300 includes a cover plate body 31 and an outer protrusion 32. The cover plate body 31 is covered on the side of the display screen 200 away from the accommodating cavity 11. The outer protrusion 32 protrudes from the side of the cover plate body 31 away from the display screen 200, and the magnetic attraction component 400 is embedded in the outer protrusion 32. Therefore, the cover plate body 31 of the cover plate 300 can be made thinner, and accordingly, the overall weight of the cover plate 300 can be made lighter, thereby reducing the overall weight and thickness of the mobile terminal protective shell.

[0075] As mentioned above, in some embodiments, the cover plate 300 may be provided with a first mounting groove 321, and the magnetic component 400 is disposed in the first mounting groove 321. Then, the first mounting groove 321 may be formed on the side of the outer protrusion 32 facing the display screen 200, and the magnetic component 400 is disposed in the first mounting groove 321.

[0076] For example, the cover plate 300 may be injection molded, and the outer protrusion 32 includes convex ribs and convex bumps on the cover plate 300 .

[0077] In some embodiments, the protective shell body 100 is provided with a camera hole 12 so that the camera of the mobile terminal accommodated in the accommodating cavity 11 can be inserted into the camera hole 12; thereby, the mobile terminal is allowed to perform operations such as taking pictures, recording videos, and scanning codes.

[0078] In some embodiments, the camera of the mobile terminal accommodated in the accommodating cavity 11 protrudes from the side of the cover body 31 away from the accommodating cavity 11 by a height of L1, and the protrusion 32 protrudes from the side of the cover body 31 away from the accommodating cavity 11 by a height of L2, and the difference between L1 and L2 is less than or equal to 0.5 mm.

[0079] Therefore, it can also be understood that the height of the mobile terminal camera and the protruding portion 32 are roughly the same. Then, when the mobile terminal protective case is placed on the desktop with the cover plate 300 facing downward, the protruding portion 32 of the mobile terminal protective case forms a first fulcrum, and the mobile terminal camera forms a second fulcrum. The at least two-point support method allows the mobile terminal protective case and the mobile terminal accommodated therein to be placed more stably, thereby improving the technical problem in the prior art that the mobile terminal camera protrudes too high and causes unstable placement.

[0080] Exemplarily, the difference between L1 and L2 may be 0.1 mm, 0.13 mm, 0.21 mm, 0.25 mm, 0.35 mm, 0.4 mm or 0.5 mm, which is not limited in the embodiments of the present application.

[0081] It should also be noted here that, taking the mobile terminal protective shell as a mobile phone shell as an example, the mobile terminal accommodated in the accommodating cavity 11 is a mobile phone of a corresponding model of the mobile terminal protective shell.

[0082] Please continue to refer to Figure 5 In some embodiments, the protective shell body 100 and / or the cover plate 300 is further provided with an annular portion 13 arranged around the camera hole 12. Thus, the annular portion 13 can provide better protection for the camera of the mobile terminal.

[0083] The height of the annular portion 13 protruding from the side of the cover body 31 away from the accommodating cavity 11 is L3. The height of the outer protrusion 32 protruding from the side of the cover body 31 away from the accommodating cavity 11 is L2, and the difference between L3 and L2 is less than or equal to 0.5 mm.

[0084] Therefore, it can also be understood that the heights of the annular portion 13 and the convex portion 32 are substantially the same. Then, when the mobile terminal protective case is placed on the desktop with the cover plate 300 facing downward, the convex portion 32 of the mobile terminal protective case forms a first fulcrum, and the annular portion 13 of the mobile terminal protective case forms a second fulcrum. The at least two-point support method allows the mobile terminal protective case and the mobile terminal accommodated therein to be placed more stably, thereby improving the technical problem in the prior art that the camera of the mobile terminal is too high to be placed unsteadily.

[0085] Exemplarily, the difference between L3 and L2 may be 0.1 mm, 0.13 mm, 0.21 mm, 0.25 mm, 0.35 mm, 0.4 mm or 0.5 mm, which is not limited in the embodiments of the present application.

[0086] It can be seen that in the embodiment of the present application, the magnetic component 400 is embedded in the outer protrusion 32 on the basis of being supported by the outer protrusion 32 as a fulcrum to ensure that the mobile terminal protective case and the mobile terminal accommodated therein can be placed more stably. This can reduce the thickness of the whole formed by the magnetic component 400 and the outer protrusion 32.

[0087] like Figure 4 As shown, in some embodiments, the outer protrusion 32 includes a first protrusion 322 and a second protrusion 323, and the first protrusion 322 is annular. The magnetic attraction component 400 includes a first magnet 41 and a second magnet 42, the first magnet 41 is annular and is disposed on the first protrusion 322, and the second magnet 42 is disposed on the second protrusion 323.

[0088] Thus, the mobile terminal protective shell can be adsorbed one-to-one with two magnetic parts of the external device through two magnetic parts (ie, the first magnet 41 and the second magnet 42) to avoid errors in the position and angle of the mobile terminal protective fixing.

[0089] It should be noted that the first magnet 41 may be annular, which means the first magnet 41 is a closed annular structure, or it may be a non-closed annular structure with at least one opening in the circumferential direction. The embodiment of the present application does not limit this.

[0090] In some embodiments, the display screen 200 includes a display area 21 for displaying, and the first convex portion 322 is disposed around the display area 21. Thus, the magnetic attraction component 400 can be prevented from blocking the display area 21 of the display screen 200, so as to improve the viewing experience of the display screen 200.

[0091] In some embodiments, the first magnet 41 is in a ring shape, and the display area 21 is also in a circle.

[0092] Optionally, the first magnet 41 may be in a square ring shape, and the display area 21 may also be in a square shape. Of course, in some other implementations, the inner edge shape of the first magnet 41 may be different from the outer edge shape of the display area 21, which is not limited in the present application.

[0093] In some embodiments, the diameter of the display area 21 is 38 mm to 50 mm, so that the larger display area 21 can fill the space on the inner side of the first magnet 41 as much as possible, thereby increasing the screen-to-body ratio of the mobile terminal protective case, and ultimately improving the aesthetics of the mobile terminal protective case.

[0094] Exemplarily, the diameter of the display area 21 is 38 mm, 38.3 mm, 38.5 mm, 38.76 mm, 38.9 mm, 39 mm, 39.12 mm, 39.41 mm, 39.5 mm, 39.7 mm, 39.88 mm, 40 mm, 40.1 mm, 40.4 mm, 40.5 mm, 41 mm, 41.04 mm, 41.3 mm, 41.5 mm, 41.8 mm, 42 mm, 42.1 mm, 42. 14 mm, 42.2 mm, 42.5 mm, 42.83 mm, 43 mm, 43.4 mm, 43.5 mm, 44 mm, 44.21 mm, 44.5 mm, 45 mm, 45.5 mm, 45.9 mm, 46 mm, 47 mm, 47.7 mm, 47.9 mm, 48 mm, 48.17 mm, 48.5 mm, 49 mm, 49.14 mm, 49.5 mm or 50 mm is not limited to the embodiments of the present application.

[0095] In some embodiments, the inner edge of the first magnet 41 coincides with the outer edge of the display area 21. Then, it can also be understood that there is no gap between the first magnet 41 and the display area 21, so that the display area 21 can cover the inner peripheral area of ​​the first magnet 41 as much as possible to increase the screen-to-body ratio of the mobile terminal protective case, and ultimately improve the aesthetics of the mobile terminal protective case.

[0096] Optionally, the distance between the inner edge of the first magnet 41 and the outer edge of the display area 21 is L4, and the outer diameter of the display area 21 is D. The ratio of L4 to D is less than or equal to 0.1, so that by reducing the gap between the display area 21 and the first magnet 41, the display area 21 can be covered as much as possible on the inner peripheral area of ​​the first magnet 41 to increase the screen-to-body ratio of the mobile terminal protective case, and ultimately improve the aesthetics of the mobile terminal protective case.

[0097] Exemplarily, the ratio of L4 to D is 0.01, 0.02, 0.034, 0.041, 0.05, 0.055, 0.06, 0.07, 0.085, 0.09, 0.097 or 0.1, which is not limited to the embodiments of the present application.

[0098] In some embodiments, the cover plate 300 (such as the cover plate body 31 ) is provided with a display window corresponding to the display area 21 . Thus, the cover plate 300 can provide a good protection effect for the display screen 200 without affecting the display of the display area 21 .

[0099] It is understandable that the cover plate 300 may be an integrally formed plate-like structure, or may be formed by splicing multiple plates, which is not limited in the embodiments of the present application.

[0100] It can also be understood that the cover plate 300 can be made of glass, acrylic, or transparent PC (Polycarbonate) material, etc., which is not limited in the embodiment of the present application.

[0101] For example, the cover plate 300 may be made of a transparent material, and a light shielding coating may be applied to the non-display window area of ​​the cover plate 300 .

[0102] The above are some examples of the magnetic attraction component 400 in the embodiment of the present application.

[0103] Please continue to refer to Figure 6 In some embodiments, the protective shell body 100 includes a bottom wall 14 located on one side in the thickness direction of the protective shell body 100. The display screen 200 can be disposed on the bottom wall 14, so that the display screen 200 can be made larger.

[0104] As mentioned above, the protective shell body 100 and / or the cover plate 300 is provided with a camera hole 12 ; therefore, the camera hole 12 may be provided through the bottom wall 14 .

[0105] As mentioned above, the protective shell body 100 and / or the cover plate 300 are also provided with an annular portion 13 arranged around the camera hole 12; then, the annular portion 13 may be formed only on the bottom wall 14, or only on the cover plate 300, or may be partially formed on the bottom wall 14 and partially formed on the cover plate 300, and the embodiments of the present application are not limited to this.

[0106] Of course, the mobile terminal protective shell may not be provided with the annular portion 13, and this embodiment of the present application does not limit this.

[0107] In some embodiments, the protective shell body 100 further includes an annular wall 15 disposed around the bottom wall 14 , so that the accommodating cavity 11 is enclosed by the bottom wall 14 and the annular wall 15 .

[0108] Optionally, the protective shell body 100 may also include two side walls (not shown in the figure), and each end of the bottom wall 14 along the length direction is connected to a side wall, so that the two side walls can clamp the mobile terminal from both ends of the length direction of the mobile terminal to accommodate the mobile terminal in the accommodating cavity 11 formed by the bottom wall 14 and the two side walls. This embodiment of the present application is not limited to this.

[0109] In some embodiments, the mobile terminal protective case further includes a radio frequency antenna 600 , which is electrically connected to the display screen 200 , and the radio frequency antenna 600 is used to transmit energy and / or information.

[0110] For example, the RF antenna 600 may be directly or indirectly electrically connected to the display screen 200. Furthermore, the RF antenna 600 may be used only to supply power to the display screen 200, or may be used only to transmit image information to be displayed to the display screen 200, or may be used to supply power to the display screen 200 and transmit image information to be displayed to the display screen 200 at the same time, which is not limited in the embodiments of the present application.

[0111] The RF antenna 600 may include a QI coil, an NFC (Near Field Communication) coil, a Bluetooth antenna, etc., which is not limited in the embodiment of the present application.

[0112] In some embodiments, the RF antenna 600 includes a coil formed by winding an enameled wire.

[0113] It is understandable that in the related art, a coil is usually formed from a thin copper-clad layer on the surface of a flexible circuit board as the RF antenna 600, so the thickness of the coil formed on the surface of the flexible circuit board is less than 10 microns. Then, when the thickness of the coil formed on the surface of the flexible circuit board is small, the efficiency of energy transmission between the RF antenna 600 and the mobile terminal is low.

[0114] In contrast, in the embodiment of the present application, the wire diameter (or diameter) of the enameled wire wound to form the coil is usually greater than the thickness of the coil formed on the surface of the flexible circuit board, for example, the wire diameter of the enameled wire can be greater than or equal to 150 microns. Therefore, the coil formed by winding the enameled wire can effectively improve the energy transmission efficiency between the RF antenna 600 and the mobile terminal.

[0115] In some embodiments, the diameter of the enameled wire may be 150 to 230 microns, thereby ensuring that the enameled wire has a large enough diameter to ensure that the coil has good energy transmission efficiency, while preventing the enameled wire from having too large a diameter, which may lead to an overly large coil and make the mobile terminal protective case too thick and heavy.

[0116] For example, the wire diameter of the enameled wire can be 150 microns, 154 microns, 155 microns, 160 microns, 161.07 microns, 165.5 microns, 168.7 microns, 170 microns, 180 microns, 195 microns, 200 microns, 200.4 microns, 205 microns, 210 microns, 214.7 microns, 215.9 microns, 220 microns, 221 microns, 225 microns or 230 microns, which is not limited to the embodiments of the present application.

[0117] It can also be understood that the enameled wire has excellent electrical conductivity and insulation properties, thereby improving the energy transmission efficiency between the coil and the external device. For example, the enameled wire can be acetal enameled wire, polyester enameled wire, polyurethane enameled wire, polyesterimide enameled wire or polyimide enameled wire, etc., which is not limited in the embodiments of the present application.

[0118] In some embodiments, the RF antenna 600 and the display screen 200 are arranged side by side on the side of the cover plate 300 facing the display screen 200. Then, compared with the stacking of the RF antenna 600 and the display screen 200, the mobile terminal protective housing can be made thinner to improve the user experience.

[0119] In some embodiments, the mobile terminal protective case further includes a control circuit board 700 . The control circuit board 700 is electrically connected to the display screen 200 .

[0120] The control circuit board 700 may be disposed on a side of the display screen 200 facing the accommodating cavity 11 , that is, the control circuit board 700 may be stacked with the display screen 200 .

[0121] The control circuit board 700 can also be arranged side by side with the display screen 200 on the side of the cover plate 300 facing the accommodating cavity 11, which is not limited to this embodiment of the present application; then, compared with the stacking of the control circuit board 700 and the display screen 200, the protective shell of the mobile terminal can be made thinner to improve the user experience.

[0122] When the mobile terminal protective case further includes a radio frequency antenna 600 , the radio frequency antenna 600 may be electrically connected to the control circuit board 700 , so as to be electrically connected to the display screen 200 through the control circuit board 700 .

[0123] In some embodiments, the protective shell body 100 is provided with a second mounting groove 16 opening toward the cover plate 300 , and at least one of the control circuit board 700 , the radio frequency antenna 600 and the display screen 200 is disposed in the second mounting groove 16 .

[0124] Thus, the control circuit board 700, the radio frequency antenna 600, the display screen 200 and other parts can be assembled conveniently and quickly through the second mounting groove 16. The control circuit board 700, the radio frequency antenna 600, the display screen 200 and other parts can also be avoided.

[0125] In some embodiments, the mobile terminal protective case further includes a wire 800 , one end of the wire 800 is connected to the control circuit board 700 , and the other end of the wire 800 is connected to the RF antenna 600 , so that the control circuit board 700 and the RF antenna 600 are electrically connected.

[0126] The length of the conductive wire 800 is greater than the distance between the connection portion and the RF antenna 600 .

[0127] Then, it can also be understood that a certain length is reserved for the wire 800. Furthermore, on the one hand, it can facilitate the wiring and assembly between the control circuit board 700 and the radio frequency antenna 600; on the other hand, it can also be convenient to replace the control circuit board 700 and the radio frequency antenna 600 of different models or sizes, so as to eliminate the influence of different spacings between the control circuit board 700 and the radio frequency antenna 600 through the reserved length of the wire 800. Therefore, the embodiment of the present application has the advantages of easy assembly and good universal performance.

[0128] In some embodiments, the wire 800 may be integrally formed with the RF antenna 600. For example, the middle part of the enameled wire is wound to form the RF antenna 600, and both ends of the enameled wire are extended to form the wire 800, which is not limited in the present embodiment.

[0129] Please continue to refer to Figure 7 In some embodiments, the second mounting groove 16 includes a first sub-mounting groove 161, and the first sub-mounting groove 161 is located between the control circuit board 700 and the RF antenna 600. The wire 800 is partially accommodated in the first sub-mounting groove 161. The first sub-mounting groove 161 includes a first portion 1611 and a second portion 1612 intersecting each other, one end of the first portion 1611 faces the control circuit board 700, and the other end of the first portion 1611 faces the RF antenna 600.

[0130] Thus, one end of the wire 800 can be connected to the control circuit board 700 via the first portion 1611, and the other end of the wire 800 can be connected to the RF antenna 600 via the first portion 1611. The middle portion of the wire 800 can be bent and accommodated in the second portion 1612.

[0131] In some embodiments, the number of the first sub-mounting grooves 161 may be two, and each of the first sub-mounting grooves 161 is provided with a wire 800. For example, the number of the wires 800 may be two, and each of the first sub-mounting grooves 161 is provided with a wire 800.

[0132] The two first sub-mounting grooves 161 may be separated from each other or partially connected, which is not limited in the embodiment of the present application.

[0133] The second portion 1612 of each first sub-mounting groove 161 may protrude from a side of the first portion 1611 facing away from the other first sub-mounting groove 161 .

[0134] In some embodiments, the second mounting slot 16 includes a second sub-mounting slot 162 , and the second sub-mounting slot 162 is connected to the first sub-mounting slot 161 . The RF antenna 600 is disposed in the second sub-mounting slot 162 .

[0135] For example, the second sub-mounting groove 162 is an annular groove, and the RF antenna 600 is also annular so as to be embedded in the second sub-mounting groove 162 .

[0136] In some embodiments, display screen 200 may include an ink screen.

[0137] It is understandable that the ink screen only needs to be powered when the pixels change or when the displayed content needs to be changed. Therefore, the mobile terminal protective case does not need a built-in battery or an external power supply, and only needs to obtain a small amount of external energy through the radio frequency antenna 600.

[0138] For example, a mobile terminal such as a mobile phone may send a radio frequency signal to the radio frequency antenna 600. The mobile terminal protective shell obtains radio frequency energy through the radio frequency antenna 600 to drive the mobile terminal protective shell to work, and receives commands sent by the mobile terminal through the radio frequency antenna 600 to change the information to be displayed on the ink screen.

[0139] Of course, in some other implementations, the display screen 200 may also be a liquid crystal display module, a flexible screen, etc., which is not limited in the embodiments of the present application.

[0140] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
