In addition, the electronic device protective case can also accept power from an external power source and can also power external electronic devices. The electronic device protective case with a wireless power supply function is multifunctional and small in size.
[0038] The electronic device protective case with wireless power supply function includes a protective case body 10 and a power supply component arranged on the protective case body 10, wherein the protective case body 10 is used to provide a basis for protecting the electronic device and at the same time provide an assembly basis for the power supply component; the power supply component is used to power the electronic device located in the protective case body 10, and can also wirelessly power the electronic device located outside the protective case body 10, and it can also receive power from an external power source.
[0039] In order to realize the multi-directional power supply function, the power supply component in the protective shell of the electronic device with wireless power supply function includes a circuit board 21, a battery 22, a first wireless power supply component, and a second wireless power supply component. Among them, the battery 22 is used to store electricity or supply power to the electronic device; the circuit board 21 is provided with a power management circuit for controlling the charging and discharging of the power supply component to realize power management; the first wireless power supply component only has a unidirectional power supply function, which is used to charge the electronic device located in the protective shell body 10; the second wireless power supply component has a bidirectional charging and discharging function, which can charge the electronic device located outside the protective shell body 10, and can also receive power from an external power source (such as a wireless charger 30) to charge the battery 22 or the electronic device located in the protective shell body 10.
[0040] Specifically, the first wireless power supply component includes a first coil 23 connected to the power management circuit, the first coil 23 is a discharge coil, and the battery 22 or an external power supply supplies power to the electronic device located in the protective shell body 10 through the first coil 23. The first wireless power supply component also includes a first magnetic plate 24, and the first coil 23 is arranged on the first magnetic plate 24. The first magnetic plate 24 is located on the inner side of the battery 22, so that the first coil 23 is away from the battery 22 and discharges toward the inside of the protective shell body 10. A discharge circuit is also provided on the circuit board 21, and the power management circuit is connected to the first coil 23 through the discharge circuit. The discharge circuit can realize the control of the first coil 23 for the power supply of the electronic device inside the protective shell body 10.
[0041] Specifically, the second wireless power supply component includes a second coil 25 connected to the power management circuit. The second coil 25 is a charging and discharging coil.

The second magnetic plate 26 is located on the outer side of the battery 22, so that the second coil 25 is away from the battery 22 and discharges toward the outside of the protective shell body 10, or receives charging from the power supply outside the protective shell body 10. A charging and discharging circuit is also provided on the circuit board 21. The power management circuit is connected to the second coil 25 through the charging and discharging circuit. The second coil 25 can control the power supply to the electronic device outside the protective shell body 10 through the charging and discharging circuit, and can also control the power supply of the external power supply to the electronic device protective shell with wireless function.
[0042] In addition, in order to realize the wireless power supply of the electronic device protective case with wireless power supply function to the external electronic device, the second wireless power supply component also includes a magnetic suction member 27, which is used to magnetically absorb the electronic device paired with the second coil 25, so that the electronic device is absorbed on the back of the protective case body 10 to realize wireless charging. For example, electronic devices with magnetic absorption and wireless charging functions such as wristbands and earphone boxes can be absorbed on the back of the protective case body 10 to realize wireless charging.
[0043] like Figure 5 As shown, in the present invention, the center of the first coil 23 is higher than the center of the second coil 25 , that is, the distance from the center of the first coil 23 to the bottom end of the protective shell body 10 is greater than the distance from the center of the second coil 25 to the bottom end of the protective shell body 10 .
[0044] When in use, the electronic device is mounted inside the front side of the protective shell body 10, and the battery 22 can directly supply power to the electronic device through the first coil 23 (in this case, the electronic device will not consume its own battery power, but directly use the power of the battery 22, which increases the service life of the electronic device. For example, an iPhone can directly use an external power source instead of its own battery power), or the battery 22 charges the battery in the electronic device through the first coil. The process of the battery 22 charging the battery can be controlled by the management circuit, or by the control button 212 on the circuit board 21, which is not specifically limited in the present utility model. When necessary, an external electronic device (such as an earphone box, etc.) can also be directly placed on the back of the protective shell body 10, and the battery 22 can charge the external electronic device through the second coil 25.
[0045] like Figure 2 , Figure 4 , Figure 6 As shown, in a specific embodiment, the protective shell body 10 is integrally formed and constitutes a housing for accommodating the power supply component. Specifically, the protective shell body 10 is provided with an outwardly recessed assembly cavity 11 inside, and the power supply component is assembled in the assembly cavity 11.
[0046] The assembly cavity 11 is provided with a circuit board assembly groove 12 and a coil assembly groove 14, the circuit board 21 is embedded in the circuit board assembly groove 12, and the second coil 25 is embedded in the coil assembly groove 14. The circuit board assembly groove 12 and the coil assembly groove 14 can not only realize the stable installation of the circuit board 21 and the second coil 25, but also reduce the space occupied by the two in the protective shell body 10. Preferably, a through groove 16 for wiring is provided between the circuit board assembly groove 12 and the coil assembly groove 14 to avoid the space occupied by the wiring part.
[0047] A magnetic assembly groove 15 is also provided in the assembly cavity 11, and the magnetic attraction member 27 of the second wireless power supply assembly is embedded in the magnetic assembly groove 15. The magnetic assembly groove 15 in this embodiment is in a fan-shaped ring shape and is distributed on the periphery of the coil assembly groove 14. Through this structure, the space occupied by the power supply assembly part can be reduced as much as possible, and the thickness of the protruding part of the protective shell body 10 can be reduced.
[0048] In order to isolate the shareholder components from the electronic equipment, a protective panel 17 (such as soft flannel, or a hard partition + flannel structure) is provided inside the protective shell body 10 of the utility model. The protective panel 17 is used to isolate the power supply components and the electronic equipment located in the protective shell body 10, so that the power supply components are isolated in the assembly cavity 11. Correspondingly, the outer circle of the assembly cavity 11 is provided with an inwardly recessed panel assembly platform 13, and the protective panel 17 is embedded in the panel assembly platform 13. After the protective panel 17 of the utility model is assembled on the assembly platform, the surface of the protective panel 17 is flush with the inner surface of the protective shell body 10, so as to achieve stable installation of the electronic equipment.
[0049] In another specific embodiment, the protective shell body 10 and the power supply assembly are independent of each other, and the protective shell body 10 and the power supply assembly are assembled and connected. For example, the power supply assembly has a separate power supply shell, and the power supply shell is connected to the protective shell body 10, and the two can be detachably connected (such as plug-in, snap-on connection) or fixedly connected (such as bolt connection, etc.).
[0050] like Figure 3 , Figure 7 , Figure 8 As shown, the utility model can be set up as a fully enclosed structure or a semi-enclosed structure according to specific needs. Figure 3 In the fully enclosed structure shown, the back of the protective shell body 10 is fully enclosed, and the battery 22 obtains power from the wireless charger 30 through the second coil 25; Figure 7 , Figure 8 In the semi-enclosed structure shown, holes are opened on the protective shell body 10 to achieve different functions.
[0051] Specifically, corresponding to the board closed structure, the circuit board 21 is also provided with one or more of a charge and discharge connector 211, a control button 212, and a power indicator module, such as only including the charge and discharge connector 211 (such as a type-C interface), or the control button 212, or the power indicator module, or any two of the three, or all three. Preferably, the power indicator module can be a power indicator light 213, or a display screen, etc.
[0052] Correspondingly, in the semi-enclosed structure, the protective shell body 10 is provided with holes, specifically, the charge and discharge port 101 corresponds to the charge and discharge connector 211, the button hole 102 corresponds to the control button 212, and the power indicator hole 103 corresponds to the power indicator module (specifically the power indicator light 213).
[0053] On the basis of realizing the protection of electronic equipment, the utility model can not only wirelessly power the electronic equipment, but also wirelessly power external electronic equipment, and can also receive wireless power from the wireless charger 30, thus realizing the function of one shell with multiple uses.
