[0041] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0043] In the present application, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application. EMBODIMENT

[0044] Referring to Figures 1-4 As shown in the drawings, an electronic device protective shell assembly includes a mobile phone shell body, which includes an outer frame 1 and a base 2. The outer frame 1 and the base 2 are connected by a buckle connection, which facilitates disassembly and installation. The lower end of the outer frame 1 is integrated with a charging interface 3 and a lengthwise clamping groove 11, and the base 2 is provided with a clamping block 21 corresponding to the clamping groove 11, which enhances the connection stability. The clamping block 21 and the clamping groove 11 are tightly matched, which not only realizes the connection, but also lifts the base 2 body so that it can be distributed on the upper end surface 31 of the charging interface 3, ensuring that the charging interface is not affected by the base and can be used normally.

[0045] Of course, in addition to the buckle connection, the clamping groove 11 and the clamping block 21 can also be matched with dovetail grooves and dovetail blocks, which can also achieve stable connection and positioning of the base 2 and the outer frame 1. The buckle connection can also be replaced by magnetic connection, which sets magnets at corresponding positions of the outer frame 1 and the base 2 to realize the connection of the two by magnetic force, thereby improving the convenience of connection on the basis of ensuring disassembly.

[0046] In the present embodiment, the clamping groove 11 is in a "U" shape, which facilitates precise matching with the clamping block 21 and stable connection of the outer frame 1 and the base 2. The arc-shaped protrusion 111 protruding inward at the upper end of the clamping groove 11 can further prevent the clamping block 21 from coming out and enhance the connection reliability.

[0047] In addition, the expansion slot 22 provided in the base 2 makes it possible to diversify the application of the electronic device protective shell assembly. A small wireless charging module can be placed in the expansion slot 22 to realize wireless charging function; or a charging adapter module can be placed to realize energy storage charging and alternating current charging, meeting the diversified needs of users.

[0048] In the embodiment, the bottom wall of the card slot 11 is provided with through holes 112 communicating with the inner cavity of the outer frame 1, which facilitates the passage of lines or other components and realizes the internal and external functional communication (the number of through holes 112 in the drawing of the embodiment is three, which can be changed according to actual needs, and the number of designed through holes is between 2-8 to meet the needs of different line arrangements). The expansion slot 22 extends to the corresponding card block 21, so that the expansion function can cooperate with the card slot 11. In equivalent embodiments, the through holes 112 can be replaced by long strip-shaped openings, which are also convenient for internal communication and adapt to different sizes of components to meet the diversified design needs.

[0049] Specifically, the side plates 12 on both sides of the lower end of the outer frame 1 are inwardly retracted, which optimizes the overall structure and makes it more closely matched with the base 2. The outer frame grooves 13 distributed along the length direction of the side plates 12 are precisely adapted to the bosses 23 on the base 2. When the bosses 23 are embedded in the outer frame grooves 13, the protrusions 14 in the outer frame grooves 13 play a limiting role to prevent the bosses 23 from sliding randomly, thereby stabilizing the connection between the outer frame 1 and the base 2.

[0050] In addition to being distributed in a step-up shape as shown in Figure 2 , the side plates 12 in the embodiment can also adopt a monolithic structure as shown in Figure 5 , and the length and width of the side plates 12 are not limited.

[0051] Further, the side plate 12 adjacent to one side of the outer frame groove 13 is provided with a guide arc surface 121, which is to provide guidance for the embedding of the boss 23 of the base 2 into the outer frame groove 13 when assembling the phone case. When installed, the boss 23 can naturally slide into the guide arc surface 121 and be quickly positioned. In equivalent embodiments, the guide arc surface 121 can be replaced by a guide slope, which can also realize the function of guiding assembly.

[0052] In the embodiment, the outer frame 1 on one side of the side plate 12 is provided with a step, and the charging interface 3 and the card slot 11 are disposed on the step, and the step surface is flush with the upper end surface 31 of the charging interface 3, which can ensure the flatness of the whole and avoid obstacles during use. The charging interface 3 is centrally arranged, and the card slots 11 are symmetrically distributed on both sides, which makes the structure more balanced and stable.

[0053] The weight-reducing groove 15 on the peripheral step of the clamping groove 11 reduces the weight of the mobile phone shell without affecting the structural strength. According to the equivalent embodiment, the weight-reducing groove 15 can adopt a hollow grid design, which can also achieve the purpose of weight reduction and increase the heat dissipation area of the mobile phone shell. Of course, if the weight-reducing groove 15 is not used on the outer frame 1, the normal use of the electronic device protective shell assembly is not affected.

[0054] The corners of the mobile phone shell body of the embodiment are also provided with silica gel pads, which fill the gap between the mobile phone and the protective shell, preventing the mobile phone corners from being damaged by knocking. Of course, if the silica gel pad is not used on the mobile phone shell body, the normal use of the electronic device protective shell assembly is not affected.

[0055] In the embodiment, the outer frame 1 is provided with an arc-shaped baffle 16 at the lower end to limit the position of the base 2. When the mobile phone is put into the shell, the arc-shaped baffle 16 can separate the mobile phone from the base 2 to prevent extrusion.

[0056] The embodiment optimizes and improves the position of the earpiece. The outer frame 1 is provided with sound transmission holes 24 at the lower end, and the number of sound transmission holes 24 is two corresponding to the mobile phone. The front surface of the base 2 has an earpiece structure communicating with the sound transmission holes 24. The earpiece structure includes an earpiece groove communicating with the sound transmission holes 24, and the upper end of the earpiece groove is provided with a step 25, and the step 25 is firmly fixed with a mesh cloth 26. The sound played by the mobile phone enters the earpiece groove through the sound transmission hole 24 and is emitted from the mesh cloth 26. Among them, the mesh cloth 26 can effectively block dust and other foreign matters from entering, while not affecting the sound propagation. Moreover, the earpiece position is set upward, which conforms to people's daily use habits, and the sound reception is clearer during communication. According to the equivalent embodiment, the sound transmission holes 24 can be designed in different shapes, such as circular, square, etc.; the mesh cloth 26 can also be replaced by a metal filter screen, which can also achieve the dustproof sound transmission effect.

[0057] The utility model discloses a detachable setting of outer frame and base, and realizes the stable assembly of both through the cooperation of clamping groove and clamping block, buckle locking mode, the integration of charging interface on the outer frame and the application of expansion slot on the base provide the expansion space for the diversified application of mobile phone shell, and set up the earpiece on the front surface of mobile phone shell, convenient daily use.
