[0054] 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.

[0055] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of a mobile terminal protective case provided in an embodiment of the present application is shown in FIG. Figure 2 for Figure 1 The structural diagram of the mobile terminal protective case from another perspective is shown. Figure 3 for Figure 2 Schematic diagram of some parts of the mobile terminal protective case shown. The mobile terminal protective case includes a protective case body 100, a UWB module 200 and an antenna module 300. The protective case body 100 is provided with a receiving cavity 13 for accommodating the mobile terminal. The UWB module 200 and the antenna module 300 are both installed in the protective case body 100. The antenna module 300 is electrically connected to the UWB module 200, and the antenna module 300 is used to wirelessly connect to an external device to supply power to the UWB module.

[0056] Then, when a mobile terminal such as a mobile phone is accommodated in the accommodating cavity 13, the mobile terminal can establish a wireless connection with the UWB module 200 through the antenna module 300 as an external device and supply power to the UWB module 200. Furthermore, the mobile terminal can realize the UWB interaction function through the UWB module 200 in the mobile terminal protective shell to control smart home devices such as those with built-in UWB components.

[0057] In some embodiments, the antenna module 300 may include a QI coil, an NFC (Near Field Communication) coil, a Bluetooth antenna, etc., which is not limited in this embodiment of the present application.

[0058] In some embodiments, the antenna module 300 may include a coil formed by winding an enameled wire, that is, the antenna of the antenna module 300 is formed by winding an enameled wire.

[0059] It is understandable that in the related art, the antenna is usually formed by the copper cladding layer on the surface of the flexible circuit board, and the thickness of the antenna formed on the surface of the flexible circuit board is less than 10 microns. Then, when the thickness of the antenna formed on the surface of the flexible circuit board is small, the efficiency of energy transmission between the antenna and the external device is low.

[0060] In contrast, in the embodiment of the present application, the antenna of the antenna module 300 is formed by winding enameled wire. The wire diameter (or diameter) of the enameled wire is usually greater than the thickness of the antenna 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 antenna of the antenna module 300 is formed by winding enameled wire, which can effectively improve the energy transmission efficiency between the antenna module 300 and the external device.

[0061] In some embodiments, the diameter of the enameled wire may be 150 to 230 microns, thereby ensuring that the diameter of the enameled wire is large enough to ensure that the antenna module 300 has good energy transmission efficiency, while preventing the enameled wire from being too large, which may cause the antenna module 300 to be too large and the mobile terminal protective case to be too thick.

[0062] 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.

[0063] It can also be understood that the enameled wire has excellent electrical conductivity and insulation properties, which can further improve the energy transmission efficiency between the antenna module 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.

[0064] Next, the technical solution of the embodiment of the present application will be described with examples in combination with the structure of the protective shell body 100 .

[0065] The protective shell body 100 may include a bottom wall 11 located at one side in the thickness direction. The UWB module 200 may be installed on the bottom wall 11. Therefore, the installation and fixation of the UWB module 200 may be more convenient through the bottom wall 11 with a larger area.

[0066] The protective shell body 100 may further include an annular wall 12 disposed around the bottom wall 11 , so that an accommodating cavity 13 is formed by the bottom wall 11 and the annular wall 12 .

[0067] Optionally, the protective shell body 100 may also include two side walls (not shown in the figure), and each end of the bottom wall 11 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 fix the mobile terminal in the accommodating cavity 13 formed by the bottom wall 11 and the two side walls. This embodiment of the present application is not limited to this.

[0068] Then, it can be understood that the UWB module 200 can also be arranged on the annular wall 12 or the side wall, and the embodiment of the present application does not limit this.

[0069] In some embodiments, the protective shell body 100 is an integrally formed part. For example, the protective shell body 100 may be made of materials such as silicone or TPU (Thermoplastic polyurethanes), and the protective shell body 100 may be injection molded.

[0070] Please continue to refer to Figure 4 , Figure 4 for Figure 2 An exploded view of the mobile terminal protective case is shown. The mobile terminal protective case may also include a cover plate 400. The cover plate 400 is mounted on the outer wall of the protective case body 100. An installation groove 111 is formed between the cover plate 400 and the protective case body 100, and the UWB module 200 and the antenna module 300 are both arranged in the installation groove 111. Thus, the cover plate 400 can provide better protection for the UWB module 200 and the antenna module 300. In addition, the assembly of the UWB module 200 and the antenna module 300 can be completed by cooperating with the cover plate 400 and the protective case body 100, so that the mobile terminal protective case has the advantage of being easy to assemble.

[0071] Exemplarily, the outer wall (such as the bottom wall 11) of the protective shell body 100 is integrally formed with a mounting groove 111 opening toward the cover plate 400. The cover plate 400 is mounted on the outer wall of the protective shell body 100 to cover the mounting groove 111. Then, in the actual assembly process, the UWB module 200 and the antenna module 300 can be directly loaded into the mounting groove 111 from the outside of the protective shell body 100, and then the cover plate 400 is covered on the mounting groove 111 to complete the assembly.

[0072] Of course, in some other embodiments, the cover plate 400 may be provided with the above-mentioned installation groove 111. After the cover plate 400 is covered on the protective shell body 100, the outer wall (such as the bottom wall 11) of the protective shell body 100 closes the installation groove 111. The embodiment of the present application does not limit this.

[0073] In some embodiments, the bottom wall of the installation groove 111 is provided with a positioning groove 112, and the antenna module 300 includes a coil embedded in the positioning groove 112. Thus, the coil of the antenna module 300 can be conveniently and quickly installed on the protective shell body 100, and the antenna module 300 is well shaped and fixed.

[0074] For example, the positioning groove 112 may be a circular groove or an elliptical groove that matches the coil of the antenna module 300 , which is not limited in the embodiment of the present application.

[0075] Of course, in some other implementations, the bottom wall of the installation slot 111 may not be provided with the positioning slot 112 , and the antenna module 300 may be directly adhered and fixed to the installation slot 111 , which is not limited in the embodiment of the present application.

[0076] In some embodiments, the antenna module 300 and the UWB module 200 are arranged side by side on the same side of the protective shell body 100. For example, the antenna module 300 and the UWB module 200 are arranged side by side on the same side (i.e., the bottom wall 11) of the protective shell body 100 in the thickness direction. Thus, compared with the case where the antenna module 300 and the UWB module 200 are stacked on the bottom wall 11, the mobile terminal protective shell can be made thinner to improve the user experience.

[0077] In some embodiments, the protective case body 100 may be provided with a camera hole 14 .

[0078] Correspondingly, the cover plate 400 may be provided with a clearance notch 42 for avoiding the camera hole 14. Exemplarily, the clearance notch 42 may be located at one end of the cover plate 400 along the length direction of the protective shell body 100.

[0079] For example, the rear camera of the mobile terminal may be located at the upper left corner of the mobile terminal, and the camera hole 14 is also located at the upper left corner of the protective shell body 100. Correspondingly, the avoidance notch 42 may also be located at the upper left corner of the cover plate 400.

[0080] The antenna module 300 may be located at the upper right corner of the protective shell body 100 , so as to better match the NFC module at the upper right corner of a mobile terminal such as a mobile phone.

[0081] Next, the technical solution of the embodiment of the present application will be described by taking the electrical connection between the antenna module 300 and the UWB module 200 as an example.

[0082] In some embodiments, the mobile terminal protective case may further include a control circuit board 500. The control circuit board 500 is mounted on the protective case body 100 and is electrically connected to the antenna module 300. The control circuit board 500 is also electrically connected to the UWB module 200. Thus, the control circuit board 500 can wirelessly connect to the mobile terminal through the antenna module 300 to obtain energy, and then supply power to the UWB module 200.

[0083] It can also be understood that, as mentioned above, the outer wall (such as the rear wall) of the protective shell body 100 may be provided with a mounting groove 111 , and the UWB module 200 , the control circuit board 500 and the antenna module 300 may all be arranged in the mounting groove 111 .

[0084] Please continue to refer to Figure 5 , Figure 5 for Figure 4 Schematic diagram of the connection structure of the control circuit board and the antenna module. In some embodiments, the control circuit board 500 may be provided with a welding portion 51. The mobile terminal protective shell may also include a wire 600. One end of the wire 600 is electrically connected to the antenna module 300, and the other end is welded and fixed to the welding portion 51.

[0085] In some embodiments, the wire 600 may be integrally formed with the antenna module 300. For example, the enameled wire portion may extend outside the antenna module 300 to form the wire 600. Of course, the wire 600 and the antenna module 300 may or may not be integrally formed, and this embodiment of the application does not limit this.

[0086] In some embodiments, the conductive line 600 has a bent portion, and the bent portion is located between the antenna module 300 and the soldering portion 51 .

[0087] Then, it can also be understood that a certain length of the wire 600 is reserved. Furthermore, on the one hand, it can facilitate the wiring and assembly between the control circuit board 500 and the antenna module 300. On the other hand, in the actual assembly operation, when the size of the protective shell body 100 changes, the relative position of the antenna module 300 and the control circuit board 500 can be adaptively adjusted to match the protective shell body 100 of different sizes. At this time, the wire 600 can be adaptively bent and deformed to eliminate the influence of the different spacings between the antenna module 300 and the control circuit board 500, thereby avoiding the need to re-prepare antenna modules 300 and / or control circuit boards 500 of different sizes when the size of the protective shell body 100 changes.

[0088] In some embodiments, there may be at least two wires 600. The curved portion of each wire 600 has at least two bends.

[0089] In some embodiments, the length of the wire 600 is greater than the distance between the antenna module 300 and the soldering portion 51 .

[0090] Then, it can also be understood that a certain length of the wire 600 is reserved. Furthermore, on the one hand, it can facilitate the wiring and assembly between the control circuit board 500 and the antenna module 300. On the other hand, in the actual assembly operation, when the size of the protective shell body 100 changes, the relative position of the antenna module 300 and the control circuit board 500 can be adaptively adjusted to match the protective shell body 100 of different sizes. At this time, the wire 600 can be adaptively bent and deformed to eliminate the influence of the different spacings between the antenna module 300 and the control circuit board 500, thereby avoiding the need to re-prepare antenna modules 300 and / or control circuit boards 500 of different sizes when the size of the protective shell body 100 changes.

[0091] In some embodiments, the antenna module 300 can also be used to wirelessly connect to an external device to transmit information. Therefore, the mobile terminal in the accommodating cavity 13 can transmit energy and information to the control circuit board 500 through the antenna module 300, so that the control circuit board 500 can obtain energy to supply power to the UWB module 200, and the control circuit board 500 can obtain information to control the UWB module 200.

[0092] Please continue to refer to Figure 6 , Figure 6 for Figure 3 The first circuit connection schematic diagram of the antenna module and the UWB module is shown. Exemplarily, the mobile terminal protective shell also includes an NFC chip circuit 52 and a power supply circuit 53. The power supply circuit 53 is connected to the antenna module 300 to obtain power through the antenna module 300, and the power supply circuit 53 is used to connect to the UWB module 200 to power the UWB module 200.

[0093] The NFC chip circuit 52 is connected to the antenna module 300 to communicate with an external device through the antenna module 300. The NFC chip circuit 52 is also electrically connected to the UWB module 200. Furthermore, the NFC chip circuit 52 can communicate with an external device through the antenna module 300, such as obtaining a data signal, and the UWB module 200 can operate according to the data signal.

[0094] It should be noted that the NFC chip circuit 52 and the power supply circuit 53 may be at least partially formed on the control circuit board 500 , which is not limited in the embodiment of the present application.

[0095] It should also be noted that the NFC chip circuit 52 and the power supply circuit 53 are connected to the same antenna of the antenna module 300. Therefore, the antenna module 300 may include only one antenna to reduce the manufacturing cost of the mobile terminal protective shell, and also facilitate the thin and light design of the mobile terminal protective shell, thereby improving the user experience.

[0096] Of course, the antenna module 300 may also include at least two antennas, and the NFC chip circuit 52 and the power supply circuit 53 are connected to different antennas, which is not limited in the embodiment of the present application.

[0097] Please continue to refer to Figure 7 , Figure 7 for Figure 3 In some embodiments, the mobile terminal protective shell further includes a processor 54, which is connected to the NFC chip circuit 52, and the processor 54 is used to obtain a data signal sent by an external device through the NFC chip circuit 52, and drive the UWB module 200 according to the data signal.

[0098] Please continue to refer to Figure 8 , Figure 8 for Figure 3 The third circuit connection principle diagram of the antenna module and the UWB module is shown. In some embodiments, the power supply circuit 53 may include an energy storage 531 and a voltage conversion circuit 532 .

[0099] One end of the energy storage 531 is connected to the output end of the antenna module 300, and the other end of the energy storage 531 is grounded. The energy storage 531 can store the electric energy output by the antenna module 300. The energy storage 531 may include one or more energy storage capacitors, the number of which may be set as required, and the parameters of the energy storage capacitors such as capacitance and rated voltage may also be set as required, such as the number and parameters of the energy storage capacitors are set according to the driving energy required by the UWB module 200.

[0100] The input end of the voltage conversion circuit 532 is connected to one end of the energy storage 531 , the output end of the voltage conversion circuit 532 is connected to the UWB module 200 , and the voltage outputted by the output end of the voltage conversion circuit 532 is different from the voltage of the energy storage 531 .

[0101] In some embodiments, the rated voltage of the energy storage 531 may be set higher, such as 5V, 8V, 10V, 12V, 15V, 18V or even higher.

[0102] In some embodiments, the energy storage device 531 may include at least three capacitors connected in parallel. That is, the energy storage device 531 may include only three capacitors connected in parallel, or may include four, five, six, seven or even eight capacitors connected in parallel, which is not limited in the present embodiment.

[0103] Please continue to refer to Fig. 9 , Fig. 9 for Figure 3 The fourth circuit connection principle diagram of the antenna module and the UWB module shown. In some embodiments, the power supply circuit 53 may also include a matching circuit 533 and a rectifier circuit 534. The matching circuit 533 is connected to the antenna module 300 to cooperate in outputting the first electric energy. The rectifier circuit 534 is electrically connected to the matching circuit 533 to rectify the first electric energy. The energy storage 531 is connected to the rectifier circuit 534 to store the rectified first electric energy.

[0104] Furthermore, the power supply circuit 53 is connected to the antenna module 300 and can obtain electric energy through the antenna module 300 to power the UWB module 200 when the UWB module 200 is working. The mobile terminal protective shell directly obtains electric energy from the external device, and there is no need to set up a battery. There is no problem that the UWB module 200 cannot be driven when the battery is used up, which is more convenient to use. In addition, the matching circuit 533 and the antenna module 300 can cooperate to better obtain the radio frequency signal of the external device, and the rectifier circuit 534 can rectify the first electric energy output by the matching circuit 533, which is convenient for the energy storage device 531 to store electric energy.

[0105] The matching circuit 533 cooperates with the antenna module 200 to output an oscillation wave signal, the rectifier circuit 534 rectifies the oscillation wave signal and outputs a direct current signal, and the energy storage 531 stores the direct current signal.
