[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0041] See Figures 1-12 This embodiment provides a mobile phone case back panel, including:
[0042] The frame 1 has a frame body 11, the inner side of which is provided with a wrapping groove 111 for wrapping the periphery of the mobile phone, and the frame body 11 has a front opening 112 and a rear opening 113.
[0043] The back panel 2 abuts against the rear opening 113 and forms a receiving cavity with the frame body 11 to accommodate the mobile phone.
[0044] The area of the back panel 2 is less than or equal to the area of the front opening 112, and the area of the back panel 2 is greater than the area of the rear opening 113.
[0045] In this invention, by setting the frame body 11 to have a front opening 112 and a rear opening 113, and setting the area of the back plate 2 to be less than or equal to the area of the front opening 112, while the area of the back plate 2 is greater than the area of the rear opening 113, it is convenient to directly insert the back plate 2 into the frame body 11 through the front opening 112 of the frame 1, and abut it against the rear opening 113, preventing the back plate 2 from protruding from the rear opening 113. Simply placing the mobile phone into the frame body 11 then presses the back plate 2 firmly, thus fixing it in place. This structure allows for convenient and flexible matching of the back plate 2 and the frame 1, while also being easy to install, simple in structure, and stable.
[0046] In this embodiment, the frame 1 includes a top frame 114, a right frame 115, a bottom frame 116, and a left frame 117. The top frame 114, right frame 115, bottom frame 116, and left frame 117 are connected sequentially to form the frame body 11. The connecting portions between the top frame 114, right frame 115, bottom frame 116, and left frame 117 are all arc-shaped. The top frame 114, right frame 115, bottom frame 116, and left frame 117 are integrally formed and connected.
[0047] In this embodiment, the back panel 2 includes a top edge 21, a right edge 22, a bottom edge 23, and a left edge 24, which are connected sequentially. The connecting portions between the top edge 21, right edge 22, bottom edge 23, and left edge 24 are all arc-shaped, and at least one connecting portion is provided with a clearance groove 3. The length and shape of the clearance groove 3 are the same as the arc curvature and length of the connecting portion, which is equivalent to flattening a part of the connecting portion between the top edge 21, right edge 22, bottom edge 23, and left edge 24 to form an arc-shaped groove with a height smaller than the other parts. The setting of the clearance groove 3 can improve the adaptability between the back panel 2 and the frame 1, so that even if there are slight deviations in their dimensions, they can be assembled smoothly.
[0048] In this embodiment, a second back plate 4 is provided on the back of the back plate 2. The second back plate 4 and the back plate 2 are combined to form at least one ring of steps 5. The area of the second back plate 4 is less than or equal to the area of the rear opening 113. The provision of the second back plate 4 allows the steps 5 to abut against the rear opening 113 when the back plate 2 abuts against it. The second back plate 4 extends into the rear opening 113, thereby achieving that the second back plate 4 is flush with or protrudes from the back of the frame 1, thus improving the flatness of the phone case or expanding its functionality. The second back plate 4 and the back plate 2 are integrally connected.
[0049] In this embodiment, all four corners of the second back plate 4 are arc-shaped, and each of the four corners of the second back plate 4 is provided with a clearance groove 3. The length and shape of the clearance groove 3 are the same as the arc curvature and length of the four corners, which is equivalent to flattening a part of the connecting part of the four corners to form an arc-shaped groove with a height smaller than the other parts. The setting of the clearance groove 3 can improve the adaptability of the second back plate 4 to the rear opening 113 on the frame 1. Even if there is a slight deviation in the size of the two, they can be assembled smoothly.
[0050] In this embodiment, each of the four sides of the frame 1 extends inward with a limiting part 6, and the limiting part 6 and the frame 1 combine to form a rear opening 113. The limiting part 6 can be adjusted in shape, size and number as needed to facilitate the installation of the back panel 2, or to expand other functions on the frame 1.
[0051] In this embodiment, the top frame 114 extends a first protrusion 61 towards the bottom frame 116, the right frame 115 extends a second protrusion 62 towards the left frame 117, the bottom frame 116 extends a third protrusion 63 towards the top frame 114, and the left frame 117 extends a fourth protrusion 64 towards the right frame 115. The first protrusion 61, the second protrusion 62, the third protrusion 63 and the first protrusion 64 are connected in sequence to form a limiting part 6. The limiting part 6 and the frame 1 are combined to form a rear opening 113.
[0052] In this embodiment, a camera hole 25 is provided on the back plate 2, the camera hole 25 penetrates the back plate 2, and a camera protection frame 7 is snapped onto the camera hole 25.
[0053] In this embodiment, the camera protection frame 7 includes a frame body 71 and a support frame 72. The support frame 72 is rotatably connected to the frame body 71 via a pivot 73, allowing the support frame 72 to move to overlap with the frame body 71 or form a support angle with the frame body 71. The support frame 72 enables the camera protection frame 7 to function as a stand, providing multi-angle support when using a mobile phone.
[0054] In this embodiment, the wrapping groove 111 is filled with a buffer layer 8. The buffer layer 8 is made of TPU material, and the frame body 11 is made of PC material. The buffer layer 8 serves two purposes: firstly, it cushions the periphery of the phone; secondly, it works in conjunction with the back panel 2 to better improve the fit between the back panel 2 and the frame 1. That is, even if the frame 1 is slightly larger than the back panel 2, the buffer layer 8 can compensate for this error by deformation, allowing the back panel 2 and the frame 1 to fit together.
[0055] In this embodiment, a button through-hole 12 is provided on the frame 1, and a button 13 is detachably provided on each button through-hole 12. The above structure can further improve the free combination of buttons 13, and further improve the compatibility of the phone case.
