Description
Technical Field
[0001] The utility model relates to the field of mobile phone accessories, in particular to a wireless charging mobile phone case. Background Art
[0002] With the progress of technology, mobile phones have become indispensable electronic devices in people's daily lives, and the types of mobile phone cases produced accordingly in the market are becoming increasingly diverse. Currently, there are mainly mobile phone cases that only provide anti-collision functions simply, and mobile phone cases that provide both charging and anti-collision functions.
[0003] However, both of these two types of mobile phone cases have relatively obvious drawbacks. The mobile phone case that only provides anti-collision protection function simply cannot provide a charging function, and when the user's mobile phone needs to be charged, it cannot charge the mobile phone; although the mobile phone case with both charging and anti-collision functions provides both a charging function and an anti-collision function, since the battery in the case and the mobile phone case are of an integrated structure, when the battery power in the mobile phone case is exhausted, it cannot continue to provide charging support for the mobile phone, and thus cannot relieve the user's mobile phone power consumption anxiety; in addition, most of the charging mobile phone cases on the market adopt a charging plug placed on the case body, and after the plug on the case body is inserted into the charging interface of the mobile phone, wireless charging is carried out for the mobile phone. However, frequent plugging and unplugging of the plug with the mobile phone charging interface may cause wear of the mobile phone charging interface, and thus may lead to the inability to continue powering the mobile phone.

[0004] The present utility model provides a wireless charging mobile phone protective case, which includes a protective frame, a back cover and a front cover. The back cover and the front cover are fixedly connected to form the support shell main body of the mobile phone protective case. A wireless charging device is arranged inside the support shell main body to wirelessly charge the mobile phone. And the support shell main body and the protective frame are detachably connected, and they are independent structures. Through this detachable connection, the support shell main body can be replaced at any time. When a user purchases this product, an additional support shell main body containing a wireless charging device will be given. When the user uses this product to wirelessly charge the mobile phone, after the power in the first support shell main body is exhausted, the support shell main body can be detached from the protective frame for charging, and then the additional second support shell main body can be replaced to charge the mobile phone. When the second support shell main body runs out of power, the fully charged first support shell main body can be replaced to continue charging the mobile phone. Through this way of cyclic power supply, continuous charging support is provided for the mobile phone, which not only alleviates the user's electricity consumption anxiety but also continuously provides anti-collision protection for the mobile phone. At the same time, this way of wirelessly cycling power supply for the mobile phone enhances the user's activity range during use, and the user can use this device to power the mobile phone in any activity space. Moreover, the present utility model uses magnetic induction charging to power the mobile phone, avoiding damage to the mobile phone charging interface caused by the plug-and-play connection method.

[0036] The present utility model will be further described in detail below with reference to the accompanying drawings through specific embodiments.
[0037] According to an embodiment of the present utility model, as Figure 1 and Figure 2 shown, a wireless charging mobile phone protective case includes:
[0038] a protective frame 1, a back cover 2, a PCB substrate 3, a battery 4, a wireless coil 5 and a front cover 6;
[0039] The inner surface edge of the protective frame 1 bulges inward to form an annular bearing beam for connecting the back cover 2;
[0040] The edge of the back cover 2 is formed with an annular stepped beam that engages with the annular bearing beam in a concave-convex manner;
[0041] The front cover 6 is fixedly connected to the back cover 2;
[0042] The PCB substrate 3, the battery 4 and the wireless coil 5 are all fixed in the cavity between the back cover 2 and the front cover 6.
[0043] Traditional mobile phone cases can only provide anti-collision function but not charging function, and cannot meet users' increasingly prominent demand for diverse functions of mobile phone cases. However, for mobile phone cases with wireless charging, the battery and the case inside the case are an integrated structure and cannot be disassembled. When the battery in the case is exhausted and can no longer power the mobile phone, only wired charging can be selected to continue to power the mobile phone. However, the wired charging method, due to the limitation of the charging cable, greatly restricts the user's usage scenarios and scope, thereby limiting the user's use space of the mobile phone.
[0044] In view of the above problems, the inventor of the present application has designed a wireless charging mobile phone protective case, comprising: a protective frame 1, a back cover 2 and a face cover 6. The back cover 2 and the face cover 3 of the product are fixedly connected to form a supporting shell body of the mobile phone protective case. The supporting shell body contains wireless charging devices such as a PCB substrate 3, a battery 4 and a wireless coil 5, and the supporting shell body can be detachably connected to the protective frame 1. Through this detachable connection, the supporting shell body can be replaced at any time. When the user purchases this product, a supporting shell body containing a wireless charging device will be given as a gift. When the user uses this product to wirelessly charge the mobile phone, after the power supply in the first supporting shell body is exhausted, the supporting shell body can be removed from the protective frame 1. The protective shell 3 in this embodiment uses a built-in chip protocol switch to control the charging mode. When the protective shell is placed on an external wireless charging device, the mobile phone will be charged first. When the mobile phone is fully charged, the built-in battery of the mobile phone protective shell will be wirelessly charged to ensure that the charging needs of the user are met first.
[0045] Furthermore, the annular load-bearing beam and the annular step beam are detachably connected with concave-convex fit.
[0046] In this embodiment, the detachable connection between the supporting shell body and the protective frame 1 is achieved through the concave-convex matching structure, making the connection and replacement of the two simple and easy to operate, saving time during the replacement process.
[0047] Furthermore, the inner and outer surfaces of the PCB substrate 3 are respectively fitted and connected to the two wireless coils 5, and the battery 4 is located below the PCB substrate 3 and is connected to the circuit of the PCB substrate 3; wherein the PCB substrate 3 is a ring structure, and the outer diameter of the ring is equal to the outer diameter of the wireless coil 5.
[0048] In this embodiment, the PCB substrate 3 can be an FR-4 substrate, a Cem-1 substrate, an FR-2 substrate, etc.; two wireless coils 5 are respectively attached to the inner and outer surfaces of the PCB substrate 3. The outer surface of the PCB substrate 3 is attached to the wireless coil 5 for charging the mobile phone, and the inner surface of the PCB substrate 3 is attached to the wireless coil 5 for charging the battery 4. The inventor of the present application innovatively implants the wireless coil 5 on the low-cost PCB substrate 3, and their sizes are almost equal. In this way, the two can be fixed on the back cover 2 or the front cover 6 as a mounting surface, further saving and controlling the thickness dimension of the support shell while also controlling its cost, and facilitating the design, development, and production of the product.
[0049] Further, the back cover 2 and / or the front cover 6 are provided with a groove for placing the battery 4, and the battery 4 is connected to the back cover 2 and / or the front cover 6 through the groove; a heat sink is also provided in the groove.
[0050] In this embodiment, by providing a groove in the back cover and the front cover of the mobile phone protective case, the space of the protective case can be effectively utilized to place the battery. The groove design can provide a suitable fixing space for the battery without increasing the overall thickness of the protective case. This enables the mobile phone protective case to maintain a suitable size design; in addition, the heat sink in the groove can provide a good heat dissipation effect. The battery generates heat during operation, and through the heat sink, the heat dissipation can be accelerated, preventing the battery from overheating and improving the working efficiency and lifespan of the battery.
[0051] Further, the outer surface of the protective frame 1 is also provided with anti-slip patterns.
[0052] In this embodiment, applying the anti-slip pattern design to the outer surface of the protective frame 1 can improve the comfort of the user's grip, prevent scratches, enhance the aesthetic appearance, and increase the anti-collision performance.
[0053] Further, the protective frame 1 is also provided with finger holes.
[0054] In this embodiment, through the finger holes, the mobile phone in the protective case can be taken out more conveniently and quickly.
[0055] Further, the protective frame 1 is also provided with a wired charging port.
[0056] In this embodiment, the wired charging port plays a backup role during the charging process. When the battery 4 in the mobile phone protective case runs out of power or is damaged, the mobile phone can still be charged through the wired charging port while providing anti-collision protection for the mobile phone.
[0057] Further, the protective frame 1 is also provided with a camera frame.
[0058] In this embodiment, the camera frame can effectively protect the camera lens from being knocked or scratched; in addition, the camera frame matches the overall design of the mobile phone case, thereby enhancing the aesthetics of the mobile phone case.
[0059] The specific embodiments described above have further elaborated on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
