[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Refer to the instruction manual Figure 1-6 The present invention provides a mobile phone case with a color card display function, comprising a housing 1, an opening 2 being formed at the rear end of the housing 1, a back panel 3 being provided inside the opening 2, and an EPD electronic paper display 4 being provided at the front end of the back panel 3. Specifically, the EPD electronic paper display 4 is a display technology that combines the advantages of ordinary paper and electronic displays. EPD utilizes colored charged particles that, under the action of an external electric field, move in a liquid environment to present different color effects.

[0027] like Figure 7 As shown, the EPD electronic paper display 4 system hardware includes SOC control center, E_Ink drive and control, NFC chip, SOC power supply module, power storage unit, EBC control signal, data storage unit, SOC debugging interface. Specifically, the SOC control center is a low-power MCU, which communicates with the EPD electronic paper display 4 through EBC control signals for display, and the EPD driver chip and the low-power MCU are configured and updated using the I2C interface protocol;

[0028] When the EPD electronic paper display 4 system is working, it relies on the NFC chip 15 for near-field power supply, driving the SOC power supply module to provide power to the low-power MCU. At the same time, the power supply module of the power storage unit stabilizes the voltage of the power supply system and stores power. After the NFC chip 15 stops charging, the system can maintain voltage stabilization for 5 minutes.

[0029] When the system starts, the color card matrix data is read from the data storage unit to update the display. In addition to power supply, the NFC chip 15 also communicates with the mobile phone for data. After obtaining the updated data, it updates the EPD electronic paper display 4 screen through the EBC control signal and writes it back to the data storage unit for storage.

[0030] Each time the NFC chip 15 wakes up, if no command reaches the low-power MCU within 30 seconds, the system automatically enters a dormant state, the DDR and data storage units are powered off, and the EPD electronic paper display 4 is powered off to maintain the display;

[0031] The system reserves the SOC control center, and the SOC debug interface can be used to manage the 30-second sleep exit mechanism on / off in the working state;

[0032] The EPD electronic paper display 4 is snap-fitted to the housing 1. An NFC chip 15 for power supply is fixedly embedded in the front end of the EPD electronic paper display 4 to connect the EPD electronic paper display 4 to the mobile phone. Multiple plug-in blocks 5 are fixedly mounted on the outer walls of both sides of the back panel 3. Multiple slots 6 are formed on both sides of the rear end of the opening 2. The plug-in blocks 5 are plugged into the slots 6.

[0033] Furthermore, the plurality of inserting blocks 5 are integrally formed with the back plate 3. A plurality of clamping blocks 8 are fixedly provided at the front end of each inserting block 5. A plurality of clamping slots 9 are provided on the inner wall of the rear end of each slot 6. The clamping blocks 8 are clamped with the clamping slots 9. The clamping of the clamping blocks 8 with the clamping slots 9 can improve the firmness between the back plate 3 and the housing 1.

[0034] A mounting hole 12 is provided at the top rear end of the back panel 3. The mounting hole 12 is located above the EPD electronic paper display screen 4 and is used to install the camera part of the mobile phone. A plurality of heat dissipation holes 13 are provided on the back panel 3. The plurality of heat dissipation holes 13 are located on one side of the mounting hole 12, and the plurality of heat dissipation holes 13 are distributed in a linear array on the back panel 3 to facilitate heat dissipation of the EPD electronic paper display screen 4. A plurality of heat dissipation holes 14 are provided on both sides of the front end of the shell 1. The plurality of heat dissipation holes 14 are distributed in a linear array on the shell 1 to facilitate heat dissipation of the shell 1.

[0035] When the shell 1 is put on a mobile phone for use, the EPD electronic paper display 4 on the shell 1 is tightly attached to the back of the mobile phone through the NFC chip 15. Through the DIY Lamp APP that interacts with the mobile phone and the EPD electronic paper display 4 system, the user uses this APP to select a template, customize the theme of the EPD electronic paper display 4, and transmit it to the EPD electronic paper display 4 through the NFC chip 15 for display. At the same time, the EPD electronic paper display 4 draws power from the mobile phone through the NFC chip 15 to ensure the normal operation of the EPD electronic paper display 4. Multiple themes are preset in the mobile phone DIY Lamp APP, such as color themes, number themes, letter themes, etc. Users can quickly select preset themes through the APP, or create new themes by DIYing the colors of each EPD electronic paper display 4, so that the single-function shell 1 has a multi-functional color card display function, realizing the personalized customization and display function of the shell 1, avoiding aesthetic fatigue caused by long-term use by users, and thus reducing usage costs and waste of resources.

[0036] Refer to the instruction manual Figure 1-6 , the rear end top and bottom of the shell 1 are both provided with a support assembly 7, the support assembly 7 includes two sliders 701, the rear end top and bottom of the shell 1 are both provided with a groove 702, the two sliders 701 are respectively slidably arranged in the two grooves 702, a long plate 703 is fixedly provided on one side of the slider 701, a threaded hole 704 is provided on the side of the long plate 703 away from the slider 701, and a threaded rod 705 is threadedly connected to the threaded hole 704;

[0037] The rear ends of the two sliders 701 are fixed with a pin 10, and the inner walls of the rear ends of the two grooves 702 are provided with multiple holes 11 that are compatible with the pin 10. The pin 10 is plugged into one of the holes 11, and the position of the slider 701 is easily adjusted by using the pin 10 and the hole 11.

[0038] By setting a back panel 3 on the back of the EPD electronic paper display 4, the back panel 3 can protect the EPD electronic paper display 4, and the multiple heat dissipation holes on the back panel 3 can be used to dissipate heat from the EPD electronic paper display 4. Remove the shell 1 from the mobile phone, then rotate the two long plates 703 in turn, and rotate the threaded rod 705 to adjust the length of the threaded rod 705 extending out of the long plate 703, then push the slider 701 and use the pin 10 to fix the slider 701. With the help of the two long plates 703 and the two threaded rods 705, the shell 1 can be used as an artistic digital photo frame.

[0039] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
