[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1-4 As shown, this embodiment provides a mobile phone case with display function, including a housing 1, a display screen 2, a circuit board 3, a signal receiving module 4, and a coil 5 for reverse charging of the mobile phone. The circuit board 3, the signal receiving module 4, and the coil 5 are respectively installed on or inside the housing 1. A receiving area 13 is provided in the middle of the back of the housing 1. The display screen 2 is located in the receiving area 13 and displays the content outward. The display screen 2 is electrically connected to the circuit board 3, the signal receiving module 4 is electrically connected to the circuit board 3, and the coil 5 is electrically connected to the circuit board 3. Specifically, the signal receiving module 4 is an antenna. The display screen is embedded in the receiving area and is electrically connected to the circuit board through a flexible ribbon cable. In order to realize the data transmission and display functions, this solution provides a signal receiving module in the housing and electrically connects it to the circuit board. The signal receiving module is positioned for easy connection with the phone, enabling rapid data transmission and displaying the phone's settings on the screen via the circuit board. Crucially, the coil is also electrically connected to the circuit board and placed inside the casing to achieve reverse charging, completely replacing the independent battery assembly. Users can continuously power the phone case's screen using the phone's built-in reverse wireless charging function, significantly reducing the complexity and risk of damage associated with replacing small batteries.

[0028] Preferably, the housing 1 includes a back panel 11 and side panels 12 disposed around the periphery of the back panel 11, with the edges of the back panel 11 and the side panels 12 connected together. This design also facilitates the removal and installation of the phone case. When it is necessary to replace or repair the phone, the user can easily remove the phone case from the phone without worrying about damaging the phone or the phone case. Specifically, the edge of the back panel 11 is provided with a protrusion, and the inner side of the side panel 12 is provided with a groove that matches the protrusion. The back panel 11 and the side panel 12 are engaged with each other through the protrusion and the groove.

[0029] Preferably, the backplate 11 is composed of an upper backplate 111 and a lower backplate 112. In this embodiment, they are assembled by adhesive bonding, which is simple and convenient. The receiving area 13 is disposed on the upper backplate 111, and the signal receiving module 4 is disposed between the upper backplate 111 and the lower backplate 112. A connecting hole 14 is provided in the upper backplate 111 to connect the receiving area 13. The upper backplate has a receiving area that matches the size of the display screen. The lower backplate and the upper backplate work together to form an internal space for installing the signal receiving module and the battery. Specifically, the required components can be placed and wiring can be easily connected by slotting in a certain area of ​​the upper backplate 111. The advantages of this structure are as follows: First, the upper and lower back panels can be injection molded with different materials and colors, achieving both aesthetic and functional requirements through two-color injection molding or post-painting; second, the connecting holes in the upper back panel are directly connected to the receiving area, facilitating the electrical connection of the signal receiving module or battery to the external space through the holes; finally, the lower back panel can also reserve wire grooves and wiring channels, making the connection between the circuit board and the signal module neat and aesthetically pleasing, and eliminating the need to affect the display area during maintenance.

[0030] Compared to relying solely on a continuous external power supply, preferably, a battery 6 is also included. The battery 6 is disposed on or inside the housing 1, and the battery 6 is electrically connected to the circuit board 3. By integrating the battery inside the phone housing and directly connecting it to the circuit board via electrical connection, the battery can be charged when the phone is reverse-charged. When the phone is out of charging range or turned off, the battery in the phone housing can continuously supply power to the display screen to meet usage needs.

[0031] Preferably, the coil 5 and the circuit board 3 are disposed on the back of the display screen 2, and a magnetic shielding sheet 7 is disposed between the coil 5 and the circuit board 3. Specifically, the display screen, the coil, and the circuit board are disposed together in the receiving area. The coil is connected to the magnetic shielding sheet by adhesive. The shape and size of the magnetic shielding sheet match the shape and size of the receiving area. It can be connected by adhesive after applying adhesive around the magnetic shielding sheet to the inner wall of the matching receiving area. This connection process is simple and convenient. The magnetic shielding sheet is made of high magnetic permeability iron-silicon alloy material, and its thickness and size are strictly matched with the coil plane, which can effectively shield the magnetic field generated by the coil in a designated area. At the same time, the magnetic shielding sheet is fixed to the back plate by a combination of screws and buckles to ensure that it does not shift under long-term vibration or temperature change environment. Insulating pads are also attached to the four edges of the magnetic shielding sheet to prevent short circuits between the metal and the circuit board. This structure not only ensures the high efficiency of reverse charging and wireless charging, but also avoids electromagnetic noise interference to high-sensitivity displays such as e-ink screens.

[0032] Preferably, the receiving area 13 is groove-shaped, and the shape and size of the display screen 2 match the shape and size of the receiving area 13. The display screen, coil, and circuit board are all placed in the groove, and the aforementioned connecting hole is provided at the bottom of the groove to facilitate electrical connection between the battery and the signal receiving module and the circuit board.

[0033] Preferably, the display screen 2 is an e-ink screen. E-ink screens have advantages such as ultra-low power consumption, strong readability under sunlight, and no viewing angle limitations. In terms of implementation, the e-ink screen main control board is connected to the circuit board via a flexible FFC cable and fixed in the receiving area. It can be connected by adhesive around the display screen and to the matching inner wall of the receiving area, which is a simple and convenient connection process.

[0034] Preferably, the material of the casing 1 is PC or acrylic. PC and acrylic materials are lightweight and easy to process. This allows the phone casing to maintain sufficient strength without adding excessive weight to the phone. At the same time, both materials have good plasticity and processability, allowing for customization and processing according to different design requirements to meet users' personalized needs. Furthermore, the transparency of PC and acrylic allows the antenna components to be seen, enhancing the product's aesthetic appeal.

[0035] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
