[0028] In actual application, firstly, the mobile phone 5 is positioned in the body 4, and then the transmission head 2 in the adapter 1 is plugged into the data interface of the mobile phone 5 to achieve connection. When it is necessary to connect an expansion device, the expansion device can be connected to the transmission port 3 on the adapter 1, so that data transmission between the expansion device and the mobile phone 5 is achieved through the cable and the transmission head 2. The mobile phone 5 case provided by the present application can avoid the problem of easy damage when the transmission head 2 is fixed on the mobile phone 5 case. More importantly, by setting the transmission port 3, it is possible to achieve connection and data transmission with the expansion device on the basis of the connection between the transmission head 2 and the mobile phone 5. At this time, there is no need to unplug the adapter 1, which is convenient to use and easy to operate.

[0029] The main body 4 and the adapter 1 of the present application are not an integrated structure. In actual application, the mobile phone 5 is first inserted into the main body 4, and then the adapter 1 is inserted into the mobile phone 5. By inserting the adapter 1, the connection between other functions on the main body 4 and the mobile phone 5 can be realized.

[0030] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figure 3 , the flat cable is passed through the adapter 1. The flat cable is the key to ensure that the transmission head 2 can realize data transmission with the mobile phone 5. Based on the above reasons, it is necessary to connect the flat cable between the transmission head 2 and the transmission port 3. In order to ensure the beauty and service life of the flat cable, the flat cable in this application is passed through the inside of the adapter 1, and the adapter 1 is used to protect the flat cable.

[0031] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figure 2 The side wall and bottom surface of the body 4 are provided with an escape groove for giving way to the adapter 1. After the adapter 1 is inserted into the mobile phone 5, the adapter 1 itself needs to occupy a certain volume, so it is necessary to open an escape groove on one side of the body 4, and the escape groove is adapted to the positioning portion 102 on the adapter 1 and can be an arc groove.

[0032] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figures 1 to 3 , the adapter 1 includes a positioning portion 102, and the transmission port 3 is arranged in the positioning portion 102. For more detailed description, the adapter 1 consists of two parts, one of which is the positioning portion 102, and the other is the connecting portion 101, and the transmission port 3 is provided on the positioning portion 102. It should be pointed out that the transmission port 3 can be understood as a TYPE-C female port. The transmission port 3 is fixed in the positioning portion 102. When the expansion device needs to be connected to the mobile phone 5, there is no need to remove the adapter 1 at this time. However, the TYPE-C male port on the expansion device is connected to the transmission port 3, and then the data will be transmitted between the mobile phone 5 and the expansion device through the cable and the transmission head 2.

[0033] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figures 1 to 3 , the adapter 1 also includes a connecting portion 101, which is located on one side of the positioning portion 102. One end of the transmission head 2 is fixed in the positioning portion 102 and the other end is extended outward; the cable is passed through the positioning portion 102 and the connecting portion 101. One part of the adapter 1 is the positioning portion 102 and the other part is the connecting portion 101. The connecting portion 101 is connected to the positioning portion 102 and is located on one side of the positioning portion 102. The positioning portion 102 and the connecting portion 101 can be regarded as an L-shaped structure. As a component that needs to transmit data with the mobile phone 5 interface, the transmission head 2 needs to extend outward from the connection portion 101, that is, the transmission head 2 can be regarded as a component extending outward from the connection portion 101.

[0034] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figures 1 to 3 The transmission port 3 is a TYPE-C female port, and the transmission head 2 is a TYPE-C male port. For more detailed description, the transmission port 3 can be regarded as a component inserted into the positioning part 102, and one side of the transmission port 3 is open, because only in this way can it provide data connection with the expansion device.

[0035] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figure 1 and Figure 2 , the positioning part 102 is plugged into the body 4. In order to achieve the above technical effect, it is first necessary to open an avoidance groove at the position of the body 4 located at the data interface of the mobile phone 5, and the shape of the avoidance groove needs to be compatible with the positioning part 102, so as to avoid the gap between the positioning part 102 and the avoidance groove as much as possible, ensure reliable connection and avoid the entry of impurities.

[0036] In some embodiments of the multifunctional expandable mobile phone case provided in the present application, the connection part 101 and the positioning part 102 are integrally formed and are both made of flexible materials. By integrally forming the connection part 101 and the positioning part 102, on the one hand, a series of problems such as cracks between the two can be reduced, and on the other hand, since the connection part 101 and the positioning part 102 are both made of materials with a certain degree of flexibility, the integral forming can be more convenient for production and processing.

[0037] Since the thickness of different mobile phones 5 is different and the location of the data interface may also be slightly different, the applicability is enhanced when the adapter 1 is made of rubber or other materials with a certain degree of deformation ability.

[0038] In some embodiments of the multifunctional expandable mobile phone case provided in this application, please refer to Figure 3The positioning part 102 is provided with an anti-slip surface 6 for contacting the mobile phone 5. The side of the positioning part 102 close to the transmission head 2 is set as the anti-slip surface 6, which will abut against the back of the mobile phone 5, and the friction coefficient of the surface of the anti-slip surface 6 is relatively large. Therefore, when the transmission head 2 is plugged into the data interface of the mobile phone 5, the anti-slip surface 6 fits the mobile phone 5, thereby avoiding the risk of the adapter 1 slipping out of the body 4 to a certain extent, and ensuring the reliable connection between the adapter 1 and the mobile phone 5.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
