[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a mobile phone back cover with an integrated wireless charging function, comprising a mobile phone back cover body 1 and a wireless charging module 2, wherein the wireless charging module 2 is arranged inside the mobile phone back cover, and a plurality of positioning grooves 11 are provided on the edge of the wireless charging module 2, and positioning columns 8 are installed on the inner side surface of the mobile phone back cover body 1 opposite to the positioning grooves 11, and the positioning columns 8 are inserted into the corresponding positioning grooves 11, and the positioning grooves 11 are expanded at one end away from the mobile phone back cover body 1 to form a pressure groove 9, and a pressure block 3 movably connected to the positioning column 8 is provided in the pressure groove 9, and a plurality of pressure blocks 3 are provided on the outer end surfaces of the plurality of pressure blocks 3. A limiting groove 4 is installed on the inner side surface of the mobile phone back cover body 1 opposite to the limiting groove 4.

[0022] In this embodiment, the limiting components include a limiting rod 5 and a connecting piece 6. One end of the limiting rod 5 extends into the limiting groove 4 and is arranged to abut against the inner wall surface of the limiting groove 4. One end of the connecting piece 6 is installed on the limiting rod 5, and the other end is installed on the inner side surface of the mobile phone back cover body 1. The connecting piece 6 is made of metal spring sheet, and a retreat space is formed between the limiting rod 5 and the mobile phone back cover body 1 for the limiting rod 5 to rotate outward.

[0023] In this embodiment, a socket 10 is provided at the center of the positioning column 8, one end of the socket 10 extends to the inside of the mobile phone back cover body 1, and a plug column 7 is installed on the inner side of the pressure block 3, and the plug column 7 is inserted into the socket 10.

[0024] In this embodiment, the outer end surfaces of the pressure blocks 3 are all protruding from the outer surface of the wireless charging module 2, so that the pressure blocks can contact the parts inside the mobile phone middle frame before the wireless charging module.

[0025] In this embodiment, the end face of the positioning column 8 away from the mobile phone back cover body 1 is set lower than the inner wall surface of the positioning groove 11; the inner end face of the pressure block 3 is set to abut against the inner side face of the pressure groove 9, so that after the internal parts of the pressure mobile phone are squeezed, the pressure block has a space to move toward the mobile phone back cover body, so that the wireless charging module can be better compressed.

[0026] In this embodiment, the outer ring surface of the positioning column 8 is arranged in contact with the inner ring surface of the positioning groove 11, and the contact is used to ensure the positioning effect between the positioning column and the wireless charging module, thereby avoiding swinging.

[0027] During installation, first place the wireless charging module inside the back cover of the phone. After placement, the positioning posts on the back cover of the phone can be inserted into the positioning slots of the wireless charging module. The positioning posts and positioning slots can be used to position the wireless charging module up, down, left, and right.

[0028] Then place the pressure block in the pressure groove, and insert the plug on the pressure block into the socket. After the pressure block contacts the pressure groove on the wireless charging module, the limit rod can be released. The elastic energy of the connecting piece pushes the limit rod so that the limit rod can automatically rotate into the limit groove. The pressure block and the wireless charging module can be pre-positioned by the limit rod.

[0029] After the above is completed, the back cover of the mobile phone can be fixed on the middle frame of the mobile phone. Since the pressure block protrudes from the wireless charging module, after installation, the outer end surface of the pressure block can contact the internal parts of the mobile phone. The mutual squeezing force between the two can compress the wireless charging module to complete the locking and fixation of the wireless charging module.

[0030] On the contrary, after the back cover of the mobile phone is removed from the middle frame of the mobile phone, the pressure block will lose the pressing force from the mobile phone parts. At this time, the limit rod can be pushed open and the pressure block can be taken out of the pressure groove. After losing the obstruction of the pressure block, the wireless charging module can be directly disassembled, which greatly increases the convenience.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
