[0035] Referring to Figure 1 and Figure 2 and Figure 4 , the present utility model provides a mobile phone case, including:

[0036] An inner housing 100, the front surface of the inner housing 100 (the front surface refers to the side close to the mobile phone after the mobile phone is installed) can be installed on the back surface of the mobile phone;

[0037] An outer housing 200, the outer housing 200 is disposed on the back surface of the inner housing 100 and forms a storage space 300 with the inner housing 100. The storage space 300 is provided with a first opening 310 and the storage space 300 can communicate with the outside through the first opening 310;

[0038] The electronic paper display 400 is installed in the storage space 300 and can enter and exit the storage space 300 through the first opening 310.

[0039] In practical applications, the electronic paper display 400, as an independent module, can be provided with a plug, and a socket can be provided in the storage space 300. The user pushes the electronic paper display 400 into the storage space 300 through the first opening 310 and inserts the plug into the socket, realizing the electrical connection of the electronic paper display 400. Thus, after the electronic paper display 400 is powered on, it can be used as the second screen of the mobile phone to display content, and at the same time, it can also communicate with the mobile phone to update the display content of the electronic paper display 400.

[0040] Different from the traditional ones, the electronic paper display 400 in this embodiment can be disassembled at any time. When the electronic paper display 400 is damaged, the user can more conveniently repair or replace the electronic paper display 400, and there is no need to scrap the entire mobile phone case due to the damage of the electronic paper display 400 or the housing (including the inner housing 100 and the outer housing 200), effectively reducing unnecessary losses and wastes and achieving the effect of low-carbon environmental protection.

[0041] In some embodiments, referring to Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and Appendix Figure 4 , on the side of the outer housing 200 facing away from the inner housing 100, an observation window 210 is provided. The observation window 210 faces the electronic paper display 400 and is used to display the electronic paper display 400. In practical applications, the user can view the content displayed on the electronic paper display 400 through the observation window 210.

[0042] In some embodiments, referring to Appendix Figure 3 Appendix Figure 4 , the observation window 210 is a second opening that penetrates the outer housing 200 along the thickness direction of the outer housing 200 and communicates with the storage space 300.

[0043] In some preferred embodiments, the observation window 210 is made of a transparent material. Compared with using the second opening as the observation window 210, setting the observation window 210 as a transparent material can not only protect the electronic paper display 400 but also does not prevent the user from viewing the content displayed on the electronic paper display 400.

[0044] In some embodiments, referring to Appendix Figure 4 , the opening width of the first opening 310 gradually decreases towards the direction close to the storage space 300 until it is equal to the width of the storage space 300. The first opening 310 has a larger opening facing outwards, which can facilitate the user to insert the electronic paper display 400 into the storage space 300.

[0045] In some embodiments, referring to FIGS. Figure 1 and FIGS. Figure 4 , the inner housing 100 is provided with a plurality of magnets 110 for adsorbing the inner housing 100 to the back of the mobile phone.

[0046] Generally, the inner housing 100 can be installed on the back of the mobile phone by wrapping around the four sides of the mobile phone. However, the preferred method in this embodiment is to magnetically connect the inner housing 100 to the back of the mobile phone using the magnets 110. The magnetic connection method is more convenient and is particularly suitable when there is a need to quickly replace the phone case.

[0047] In some embodiments, referring to FIGS. Figure 1 and FIGS. Figure 4 , the inner housing 100 is provided with an induction coil 120. The induction coil 120 is electrically connected to the electronic paper display 400 and is used to supply power to the electronic paper display 400. For a mobile phone with a wireless charging and discharging function, the induction coil 120 can directly obtain the electrical energy of the mobile phone and supply it to the electronic paper display 400, thereby powering on the electronic paper display 400.

[0048] In addition, the inner housing 100 can also be provided with a charging socket. The charging socket is connected to the induction coil 120 internally and can be connected to an external power source externally. When the user connects an external power source through the charging socket, the inner housing 100 can act as a wireless charging device to charge the mobile phone through the induction coil 120. In some embodiments, the induction coil 120 can also be used to enable communication between the electronic paper display 400 and the mobile phone, thereby realizing the control of the display content of the electronic paper display 400 through the mobile phone.

[0049] In some preferred embodiments, referring to FIGS. Figure 1 and FIGS. Figure 4 , the front surface of the inner housing 100 is provided with a plurality of electrical contact points 130. The electrical contact points 130 are electrically connected to the electronic paper display 400 and can be electrically connected to the mobile phone. The electrical contact points 130 are used to enable communication between the electronic paper display 400 and the mobile phone.

[0050] For a mobile phone with a plurality of electrical contact points provided on the back of the mobile phone, the inner housing 100 provided with corresponding electrical contact points 130 can also realize the control of the display content of the electronic paper display 400 through the mobile phone. Compared with transmitting data through the induction coil 120, transmitting data using the electrical contact points 130 is more stable and reliable.

[0051] In some preferred embodiments, referring to FIGS. Figure 1 and FIGS. Figure 4, on the front of the inner housing 100, there are multiple electrical contact points 130. The electrical contact points 130 are electrically connected to the electronic paper display 400 and can be electrically connected to the mobile phone. The electrical contact points 130 are used to power on the electronic paper display 400 and communicate with the mobile phone. Compared with power supply and data transmission through the induction coil 120, power supply and data transmission using the electrical contact points 130 are more stable and reliable.

[0052] In some embodiments, referring to the attached Figure 2 , attached Figure 3 and attached Figure 4 , on the side of the outer housing 200 facing away from the inner housing 100, there is a button 220. The button 220 is electrically connected to the electronic paper display 400 and is used to control the electronic paper display 400.

[0053] In this embodiment, since the electronic paper display 400 is provided as a second screen on the back of the mobile phone, during actual use, when the user operates the mobile phone from the front, the user needs to repeatedly flip the mobile phone to observe the change in the display content of the electronic paper display 400, so that the entire operation process is too cumbersome. Therefore, in this embodiment, a button 220 that can control the electronic paper display 400 is provided on the back of the mobile phone case. Thus, the user can control the electronic paper display 400 without operating the mobile phone from the front. And because the operation is on the back of the mobile phone case, the user can directly see the change in the display content of the electronic paper display 400. Its more user-friendly design is beneficial for the user to obtain a better use experience.

[0054] In the description of this specification, the description referring to terms such as "one embodiment", "certain embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the said embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0055] The above are only some embodiments of the present invention.
