Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0024] The following is combined with the attached Figures 1 to 3 The utility model is described in detail.

[0025] Example 1

[0026] Figures 1-2 A schematic structural diagram of a mobile phone case provided by an embodiment of the utility model is shown, which includes a back panel 1 and a frame 2. The difference from the existing mobile phone case is that the inner side 22 of the frame 2 is provided with a connector a3 electrically connected to the mobile phone charging port, and the outer side 21 of the frame 2 has a protrusion 23 extending outward.

[0027] It should be noted that the position of the connector a3 on the inner side 22 of the frame 2 is specifically set according to the mobile phone model that is compatible with the mobile phone case, and no specific restrictions are made here. Figures 1 to 3 This is only a schematic structure of the positional relationship between the connector a3 and the inner side surface 22 of the frame 2, and is not intended to limit the present invention.

[0028] At the same time, the specific position of the protrusion 23 on the outer side surface 21 of the frame 2 is specifically set according to the mobile phone model that the mobile phone case is adapted to, and no specific restrictions are made here. Figures 1 to 3 It is only a schematic structure of the positional relationship between the protrusion 23 and the outer side surface 21 of the frame 2, and is not intended to limit the present invention.

[0029] Since the mobile phone needs to be charged when using the mobile phone case, the charging interface of the mobile phone is exposed to the outside. At this time, dust and other debris will enter the charging interface and damage the charging interface of the mobile phone. On the other hand, the existing mobile phone has only one type of interface, and can only use the same type of charging cable to charge during use, which causes inconvenience. In order to solve the problem, the utility model makes the following improvements:

[0030] like Figures 1-2 As shown, a connector b4, a connector c5 and a connector d6 with different interface types are sequentially provided in the protruding portion 23, and the connector b4, the connector c5 and the connector d6 are electrically connected to the connector a3 respectively.

[0031] After connecting connector a3 to the charging port of the mobile phone, the charging port of the mobile phone is electrically connected to connector b4, connector c5 and connector d6 through connector a3. At the same time, the interface types of connector b4, connector c5 and connector d6 are any one of Type-C female, Micro-USB female and Lightning female. When charging, you can choose any charging cable with an interface type of Type-C male, Micro-USB male and Lightning male, which greatly improves the convenience of use.

[0032] In one example, connector b4 is a Type-C female connector, connector c5 is a Micro-USB female connector, and connector d6 is a Lightning female connector.

[0033] In another example, connector b4 is a Micro-USB female connector, connector c5 is a Type-C female connector, and connector d6 is a Lightning female connector.

[0034] In another example, connector b4 is a Lightning female connector, connector c5 is a Micro-USB female connector, and connector d6 is a Type-C female connector.

[0035] In another example, connector b4 is a Lightning female connector, connector c5 is a Type-C female connector, and connector d6 is a Micro-USB female connector.

[0036] like Figures 1-2 As shown, the interface type of connector a3 is any one of Type-C male, Micro-USB male and Lightning male.

[0037] In one example, connector a3 is a Type-C male connector.

[0038] In another example, connector a3 is a Micro-USB male connector.

[0039] In another example, connector a3 is a Lightning male connector.

[0040] like Figures 1-2 As shown, in a preferred embodiment, a circle of thermochromic layer 9 is provided around the periphery of connector b4, connector c5 and connector d6.

[0041] The role of the above-mentioned thermochromic layer 9 is that the problem of the connector b4, the connector c5 and the connector d6 can be judged according to the color change of the thermochromic layer 9, so as to facilitate the adoption of cooling measures when the temperature is too high during the charging process.

[0042] Furthermore, the back plate 1 is made of a thermochromic material, and its function is to judge the temperature of the mobile phone according to the color change of the back plate 1, so as to facilitate taking cooling measures when the temperature is too high during charging or use.

[0043] Example 2

[0044] On the other hand, existing mobile phone cases also hinder the dissipation of heat generated during the use of the mobile phone, causing the problem of overheating of the mobile phone.

[0045] In this embodiment, based on the structure of embodiment 1, a heat dissipation structure is provided on the back plate 1, which is as follows:

[0046] The heat dissipation structure includes a heat dissipation hole a11 provided on the upper inner surface of the back plate 1 and a heat dissipation hole b12 provided on the upper inner surface of the back plate 1 , which are used to dissipate heat from the mobile phone.

[0047] Furthermore, at least two convex ribs 7 are embedded in the middle portion of the inner surface of the back plate 1 , and air flow channels 8 are formed between adjacent convex ribs 7 .

[0048] The function of the convex rib 7 is that the convex rib 7 can maintain a certain distance between the mobile phone and the mobile phone case. In the present embodiment, the height of the convex rib 7 is set to 0.3-0.5 mm, preferably 0.5 mm. After the air flow channel 8 is formed between adjacent convex ribs 7, the air flow between the heat dissipation holes a11 and the heat dissipation holes b12 is enhanced, the heat dissipation capacity of the mobile phone case is enhanced, the heat dissipation generated during the use of the mobile phone is avoided, and the heat dissipation effect is improved.

[0049] In a preferred embodiment, the convex rib 7 passes through the back plate 1 and is exposed outside the outer side 21 of the back plate 1, and the convex rib 7 is made of a thermochromic material. Its function is to judge the temperature of the mobile phone according to the color change of the convex rib 7, so as to facilitate cooling measures when the temperature is too high during charging or use.

[0050] The above-mentioned thermochromic material and the thermochromic layer 9 are made of thermochromic silica gel material, which can produce corresponding color changes according to temperature changes. Its working principle is existing technology and will not be repeated here.

[0051] The specific working principle is that after the mobile phone is installed in the mobile phone case, connector a3 is connected to its charging interface, and it can be charged through any interface of connector b4, connector c5 and connector d6, which not only prevents dust and other debris from entering the charging interface of the mobile phone and protects the charging interface of the mobile phone, but also multiple connectors b4, connector c5 and connector d6 with different interface types expand the types of charging interfaces of the mobile phone, and can be charged with charging cables of various interface types, which is easy to use. On the other hand, the heat dissipation structure arranged in the back panel 1 facilitates the heat dissipation of the mobile phone during use. Compared with the existing mobile phone cases, it can enhance the heat dissipation performance of the mobile phone case to avoid overheating of the mobile phone.

[0052] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
