[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0049] It should be noted that, in this application, "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the associated objects are in an "or" relationship.

[0050] 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, and the embodiment of the present application does not limit this.

[0051] Please refer to Figure 1 and Figure 2The mobile terminal protective case includes a protective case body 100, a display screen 200, and an antenna 300. The protective case body 100 includes a bottom wall 11 and side walls 12. The side walls 12 are connected to the peripheral edges of the bottom wall 11 to define a receiving cavity 13 between the bottom wall 11 and the side walls 12. The receiving cavity 13 is used to accommodate the mobile terminal. The bottom wall 11 is also provided with a camera hole 111. The camera hole 111 is connected to the receiving cavity 13 to allow the mobile terminal in the receiving cavity 13 to take pictures. The display screen 200 is provided on the protective case body 100. The antenna 300 is at least partially provided on the side wall 12. The antenna 300 is electrically connected to the display screen 200. The antenna 300 can be wirelessly connected to an external device to provide power to the display screen 200.

[0052] Then, for mobile terminals such as mobile phones, even if the rear camera module of the mobile terminal occupies a larger position on the bottom wall 11, the embodiment of the present application can also set part of the antenna 300 on the side wall 12 and part of it on the bottom wall 11, or set the entire antenna 300 on the side wall 12, thereby improving the technical problem that it is difficult to set the radio frequency antenna 300 in the protective case of the mobile terminal.

[0053] That is, the antenna 300 may be disposed only on the side wall 12 , or the antenna 300 may be partially disposed on the side wall 12 and partially disposed on the bottom wall 11 , which is not limited in the embodiment of the present application.

[0054] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the side wall 12 includes a first side wall 121 , which extends along the length of the bottom wall 11 . The antenna 300 includes a first portion 31 , which is disposed on the first side wall 121 .

[0055] In some embodiments, the side wall 12 includes a second side wall 122 . The second side wall 122 extends along the width direction of the bottom wall 11 . The antenna 300 includes a second portion 32 . The second portion 32 is disposed on the second side wall 122 .

[0056] It should be noted that the antenna 300 may include only one of the first part 31 and the second part 32; the antenna 300 may also include the first part 31 and the second part 32 at the same time, which is not limited in the embodiment of the present application.

[0057] When the antenna 300 includes only the first portion 31 , that is, in the first arrangement position of the antenna 300 , the side wall 12 includes a first side wall 121 . The first side wall 121 extends along the length direction of the bottom wall 11 , and the antenna 300 is disposed on the first side wall 121 .

[0058] Furthermore, on the one hand, since the first side wall 121 is longer, there is a larger installation position inside the first side wall 121, so that a larger antenna 300 can be set inside the first side wall 121, or the position of the antenna 300 inside the first side wall 121 can be adjusted more flexibly, thereby improving the efficiency of the antenna 300 in obtaining energy when wirelessly connecting to an external device.

[0059] In addition, for mobile terminals such as mobile phones, the top and bottom of the mobile phone are usually provided with more side functional structures such as charging ports, card tray installation ports, speaker ports and optical sensors. After the mobile phone is installed in the mobile terminal protective case, the first side wall 121 is located on the side of the mobile phone, so that the antenna 300 will not block the charging port, card tray installation port, speaker port and proximity light sensor.

[0060] When the antenna 300 includes only the second portion 32 , that is, in the second arrangement position of the antenna 300 , the side wall 12 includes a second side wall 122 , the second side wall 122 extends along the width direction of the bottom wall 11 , and the antenna 300 is disposed on the second side wall 122 .

[0061] For example, the side wall 12 of the protective shell body 100 may be provided with only two second side walls 122 . Therefore, compared with the side wall 12 provided around the peripheral edge of the bottom wall 11 , the embodiment of the present application can make the protective shell body 100 lighter.

[0062] For example, for a mobile phone, the protective case body 100 can clamp the mobile phone from both ends of the length direction of the mobile phone through the two second side walls 122, that is, one second side wall 122 is stuck at the top of the mobile phone, and the other side wall 12 is stuck at the bottom of the mobile phone, so that the mobile phone is accommodated in the accommodating cavity 13.

[0063] When the antenna 300 includes both the first part 31 and the second part 32, that is, in the third setting position of the antenna 300, the side wall 12 includes a first side wall 121 and a second side wall 122 connected to each other, the first side wall 121 extends along the length direction of the bottom wall 11, and the second side wall 122 extends along the width direction of the bottom wall 11, and the antenna 300 is partially set on the first side wall 121 and partially set on the second side wall 122.

[0064] Furthermore, the first side wall 121 and the second side wall 122 can be fully utilized to arrange the antenna 300 with a larger area, thereby improving the efficiency of energy acquisition when the antenna 300 is wirelessly connected to an external device.

[0065] In addition, when the antenna 300 is the same size, compared to setting the antenna 300 only on the second side wall 122, transferring part of the antenna 300 to the first side wall 121 can avoid interference between the antenna 300 and the horn and proximity light sensor on the top of the mobile phone.

[0066] Also, when the antenna 300 is the same size, compared to setting the antenna 300 only on the first side wall 121, transferring part of the antenna 300 to the second side wall 122 can avoid interference between the antenna 300 and the volume button and power button on the side of the mobile phone.

[0067] Please continue to refer to Figure 5 and Figure 6 In some embodiments, an antenna 300 is provided on one side of the bottom wall 11 in the circumferential direction. For example, the antenna 300 can be located on the first side wall 121 or the second side wall 122.

[0068] Optional, such as Figure 4 As shown, antennas 300 are provided on at least two sides of the circumference of the bottom wall 11. For example, the antenna 300 may be partially provided on the first side wall 121 and partially provided on the second side wall 122, which is not limited in this embodiment of the present application.

[0069] In some embodiments, along the length direction of the bottom wall 11 , the camera hole 111 and the antenna 300 are located at the same end of the protective case body 100 .

[0070] It is understandable that, continuing with the example of a mobile phone as a mobile terminal, with the development of electronic technology, mobile phones typically integrate NFC (Near Field Communication) communication modules, and the rear camera module and the NFC communication module are typically located at the top of the phone, that is, the rear camera module and the NFC communication module are typically located at the same end in the length direction of the phone. Therefore, in the embodiment of the present application, by also locating the camera hole 111 and the antenna 300 at the same end of the protective case body 100, the antenna 300 can be brought closer to the NFC communication module of the mobile phone within the accommodating cavity 13, thereby improving the efficiency of the antenna 300 in obtaining energy when wirelessly connecting to an external device such as a mobile phone.

[0071] Please combine Figure 2 and Figure 4 In some embodiments, the mobile terminal protective case further includes a decorative member 400, which is disposed on the side wall 12. A first mounting space is defined between the decorative member 400 and the side wall 12, and the antenna 300 is disposed within the first mounting space. Furthermore, the decorative member 400 prevents the antenna 300 from being exposed, thereby preventing the antenna 300 from falling off, shifting, or being accidentally damaged, thereby improving the reliability and stability of the mobile terminal protective case.

[0072] In some embodiments, the decorative element 400 may be disposed on the inner side of the side wall 12 , thereby making the appearance of the side wall 12 more concise and beautiful.

[0073] In some embodiments, the side wall 12 is provided with a third groove 123 , and the decorative member 400 is covered in the third groove 123 , so that the third groove 123 is used to form a first installation space.

[0074] For example, the decorative element 400 is disposed in the third groove 123 , so that a first installation space is formed between the groove wall of the third groove 123 and the decorative element 400 .

[0075] In some embodiments, the decorative member 400 is provided with a fourth groove, and the opening of the fourth groove faces the side wall 12 , so that the fourth groove is used to form the first installation space.

[0076] It is understandable that the first installation space can be formed only by the third groove 123, the first installation space can also be formed only by the fourth groove, or the first installation space can be formed by a combination of the third groove 123 and the fourth groove, which is not limited in the embodiment of the present application.

[0077] In some embodiments, the hardness of the decorative member 400 is greater than the hardness of the side wall 12 .

[0078] As can be understood, continuing with the example of a mobile phone as a mobile terminal, to facilitate the insertion of the mobile phone into the accommodating cavity 13 (or, in other words, to fit the mobile terminal protective case onto the mobile phone), the protective case body 100 is typically made of a deformable material, which results in a relatively low hardness of the sidewall 12. Consequently, during the process of removing or assembling the mobile terminal protective case, the sidewall 12 is susceptible to significant deformation, which could cause deformation and damage to the antenna 300.

[0079] Based on this, in the embodiment of the present application, since the hardness of the decorative part 400 is greater than the hardness of the side wall 12, during the process of disassembling and assembling the mobile terminal protective case, the part of the side wall 12 where the decorative part 400 is not provided is more likely to deform to complete the disassembly and assembly of the mobile terminal protective case, while the part of the side wall 12 of the mobile terminal protective case where the decorative part 400 is provided is not easy to deform, thereby avoiding the antenna 300 inside the decorative part 400 from being damaged after bending and deformation.

[0080] The decorative element 400 may include a non-electromagnetic shielding material such as a hard plastic element, a polymer material element, etc. For example, the decorative element 400 may be a Mylar sheet, thereby preventing the decorative element 400 from shielding the antenna 300 .

[0081] The protective case body 100 may be an integrally formed part. For example, the protective case body 100 may be made of silicone or TPU (Thermoplastic polyurethanes), and further, the protective case body 100 may be injection molded.

[0082] In some embodiments, the antenna 300 may include a QI coil, an NFC coil, a Bluetooth antenna, etc., which is not limited in this embodiment of the present application.

[0083] In some embodiments, the antenna 300 includes a coil formed by winding an enameled wire. Thus, by taking advantage of the larger diameter of the enameled wire, the antenna 300 can have better energy transmission efficiency. For example, the 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 in the embodiments of the present application.

[0084] It is also understood that the enameled wire has excellent electrical conductivity and insulation properties, thereby further improving the energy transmission efficiency between the antenna 300 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.

[0085] In some embodiments, the antenna 300 may also be a board-mounted antenna. For example, the antenna 300 may be formed on a flexible circuit board, which is not limited in this embodiment of the present application.

[0086] The above is an introduction to the antenna 300 of the embodiment of the present application. The following will continue to introduce the technical solution of the embodiment of the present application in combination with the connection structure between the display screen 200 and the antenna 300.

[0087] In some embodiments, the mobile terminal protective case further includes a control circuit board 500 , which is mounted on the protective case body 100 , and the control circuit board 500 is electrically connected to the antenna 300 and the display screen 200 , respectively.

[0088] Thus, the control circuit board 500 can establish a wireless connection with an external device such as a mobile terminal such as a mobile phone through the antenna 300, so that the control circuit board 500 can obtain energy through the antenna 300 and supply power to the display screen 200.

[0089] In some embodiments, the antenna 300 can also be used to wirelessly connect to external devices to transmit information. Therefore, a mobile terminal such as a mobile phone in the receiving cavity 13 can transmit energy and information to the control circuit board 500 via the antenna 300, so that the control circuit board 500 can obtain energy to supply power to the display screen 200, and the control circuit board 500 can obtain information to control the display screen 200 to display corresponding content.

[0090] Please continue to refer to Figure 7 、 Figure 8 and Figure 9 In some embodiments, the display screen 200 may be disposed on the bottom wall 11 , so that a display screen 200 with a larger area may be disposed by utilizing the bottom wall 11 with a larger area.

[0091] In some embodiments, the control circuit board 500 is disposed on the bottom wall 11 , so that a display screen 200 with a larger area can be disposed on the bottom wall 11 with a larger area.

[0092] It is also understood that only one of the display screen 200 and the control circuit board 500 may be disposed on the bottom wall 11, or both the display screen 200 and the control circuit board 500 may be disposed on the bottom wall 11. This embodiment of the present application is not limited to this. The following description mainly takes the case where both the display screen 200 and the control circuit board 500 are disposed on the bottom wall 11 as an example.

[0093] In some embodiments, the control circuit board 500 is disposed on the side of the display screen 200 facing the accommodating cavity 13. In other words, the control circuit board 500 and the display screen 200 can be stacked. Furthermore, compared to placing the control circuit board 500 and the display screen 200 side by side on the bottom wall 11, this stacked arrangement allows more area of the bottom wall 11 to be used as a display area, allowing the bottom wall 11 to accommodate a larger display screen 200, thereby increasing the screen-to-body ratio of the bottom wall 11.

[0094] Optionally, the control circuit board 500 is disposed on the outer peripheral side of the display screen 200, so as to be arranged side by side with the control circuit board 500. Therefore, compared with the stacking arrangement of the control circuit board 500 and the display screen 200, the bottom wall 11 can be made thinner, thereby making the mobile terminal protective case thinner, thereby improving the user experience.

[0095] In some embodiments, the mobile terminal protective case further includes a first cover plate 600, which is disposed on the bottom wall 11. A second mounting space is defined between the first cover plate 600 and the bottom wall 11, and the display screen 200 and the control circuit board 500 are both disposed in the second mounting space. Furthermore, the display screen 200 and the control circuit board 500 can be conveniently mounted to the bottom wall 11.

[0096] The first cover plate 600 is provided with a display area corresponding to the display screen 200. Thus, the first cover plate 600 can provide a good protection effect for the display screen 200.

[0097] It is understandable that the first cover plate 600 may be an integrally formed plate structure, or may be formed by splicing multiple plates, which is not limited in the embodiment of the present application.

[0098] It can also be understood that the first cover plate 600 can be made of glass, acrylic, or transparent PC (Polycarbonate) material, etc., which is not limited in the embodiment of the present application.

[0099] For example, the first cover plate 600 can be made of a transparent material. In the plane where the first cover plate 600 is located, part of the first cover plate 600 is coated with a light-shielding coating, so that the area of the first cover plate 600 not coated with the light-shielding coating forms a display area.

[0100] In some embodiments, the bottom wall 11 is provided with a first groove 112 . The first groove 112 is located on a side of the bottom wall 11 away from the accommodating cavity 13 to form a second installation space.

[0101] For example, the first cover plate 600 is mounted on the bottom wall 11 to close the first groove 112 , thereby forming a second installation space between the groove wall of the first groove 112 and the first cover plate 600 .

[0102] In some embodiments, the mobile terminal protective case further includes a conductive member 700 , and the control circuit board 500 is electrically connected to the antenna 300 via the conductive member 700 .

[0103] The conductive member 700 can be a conductive sheet, a power line, etc., which is not limited in the embodiment of the present application.

[0104] The conductive member 700 may be disposed only on the bottom wall 11 , or may be partially disposed on the bottom wall 11 and partially disposed on the side wall 12 , which is not limited in the embodiment of the present application.

[0105] In some embodiments, the protective shell body 100 further includes a wiring groove 113 that communicates with the second installation space. The conductive member 700 is at least partially disposed in the wiring groove 113, thereby providing a better positioning effect for the conductive member 700.

[0106] In some embodiments, the wiring groove 113 is at least partially disposed on a side of the bottom wall 11 facing the accommodating cavity 13 .

[0107] Furthermore, on the one hand, because the wiring groove 113 is at least partially disposed on the bottom wall 11, the conductive member 700 at the wiring groove 113 can be electrically connected to the control circuit board 500 at the bottom wall 11. On the other hand, because the wiring groove 113 is at least partially disposed on the side of the bottom wall 11 facing the accommodating cavity 13 (i.e., the inner side of the bottom wall 11), the conductive member 700 at the wiring groove 113 can be electrically connected to the antenna 300 located on the inner side of the side wall 12.

[0108] In some embodiments, the bottom wall 11 further defines a connecting hole 114 that passes through the bottom wall 11 to connect the first groove 112 and the wiring groove 113. The conductive member 700 is electrically connected to the control circuit board 500 in the second installation space via the connecting hole 114.

[0109] In some embodiments, the mobile terminal protective case may further include a second cover plate 800. The second cover plate 800 covers the communication hole 114, thereby providing better protection for the components in the communication hole 114.

[0110] For example, one end of the conductive member 700 may be passed through the communication hole 114 , and the second cover plate 800 may provide better protection for the portion of the conductive member 700 located in the communication hole 114 .

[0111] In some embodiments, a second groove 115 is further provided on the side of the bottom wall 11 facing the accommodating cavity 13, one end of the wiring groove 113 is connected to the second groove 115, and a connecting hole 114 passes through the bottom wall of the first groove 112 to the bottom wall of the second groove 115 to connect the wiring groove 113 and the first groove 112.

[0112] Furthermore, the conductive member 700 can be routed along the routing groove 113 , the second groove 115 , and the connecting hole 114 , so that one end of the conductive member 700 is connected to the antenna 300 and the other end is connected to the control circuit board 500 .

[0113] Correspondingly, the second cover plate 800 may be disposed in the second groove 115 .

[0114] In some embodiments, the display screen 200 may be an ink screen.

[0115] It is understandable that the ink screen only needs to be powered when the pixels change or when the displayed content needs to change. Therefore, the mobile terminal protective case can be powered without a built-in battery or external power supply, and can only obtain a small amount of external energy through the antenna 300.

[0116] For example, a mobile terminal such as a mobile phone can send a radio frequency signal to the antenna 300. The mobile terminal protective case obtains radio frequency energy through the antenna 300 to drive the mobile terminal protective case to work, and receives commands sent by the mobile terminal through the antenna 300 to change the information to be displayed on the ink screen.
