[0024] This application provides a mobile phone case 100, please refer to it. Figure 1-4 The phone case 100 includes a body 110, an electronic paper 120, a first magnetic clasp (not shown), a second magnetic clasp (not shown), a circuit board 130, an NFC antenna 140, and a flash unit 150.

[0025] Please refer to Figure 2-4The main body 110 has a receiving cavity 111, and the bottom of the receiving cavity 111 has a mounting area 112 and a circular display window 113. An electronic paper 120 is disposed in the receiving cavity 111, and the display area of ​​the electronic paper 120 is located in the display window 113. A first magnetic clasp is disposed on the side of the main body 110 opposite to the receiving cavity 111 and surrounds the display window 113; the first magnetic clasp is used to engage with a magnetic accessory. A second magnetic clasp is disposed in the mounting area 112 and is used to engage with a magnetic accessory to fix the phone case 100. A circuit board 130 is disposed within the receiving cavity 111 and is electrically connected to the electronic paper 120. An NFC antenna 140 is disposed within the receiving cavity 111 and is electrically connected to the circuit board 130. A flashing element 150 is integrated with the second magnetic clasp and disposed in the mounting area 112, and is arranged side-by-side with the second magnetic clasp; the flashing element 150 is electrically connected to the circuit board 130 and is used to flash when the electronic paper 120 refreshes.

[0026] This utility model discloses a mobile phone case 100 with an electronic paper 120 refresh indicator, including a body 110, an electronic paper 120, a first magnetic component, a second magnetic component, a circuit board 130, an NFC antenna 140, and a flashing component 150. The body 110 has a receiving cavity, the bottom of which is divided into an installation area 112 and a circular display window 113. The electronic paper 120 is fixed to the receiving cavity 111, with its display area facing the display window 113. The flashing component 150 and the second magnetic component are integrated into the installation area 112, and flash to indicate when the electronic paper 120 refreshes. This design solves the problem of the traditional electronic paper 120 mobile phone case 100 not showing the refresh status through timely feedback from the flashing component 150. At the same time, the magnetic structure facilitates installation and removal, and the appearance is simple.

[0027] In this application, when the electronic paper 120 does not need to refresh the pattern, the flash element 150 is in a normally dark state. Besides this, the electronic paper 120 has three other operating states: first, when the NFC antenna 140 of the phone case 100 is connected to the phone's NFC antenna, the flash element 150 flashes slowly; second, when the pattern transmission is complete, the flash element 150 flashes quickly; and third, after the image transmission is complete and the pattern display on the electronic paper 120 is stable, the flash element 150 remains constantly lit for a few seconds. In the embodiments of this application, the flash element 150 is a packaged surface-mount LED.

[0028] Please refer to Figure 3 The mounting area 112 has a mounting groove 1121 that extends through the bottom of the receiving cavity 111. The flashing element 150 is disposed in the mounting groove 1121. The phone case 100 also includes a plastic part 160. The plastic part 160 covers the mounting groove 1121 on the side of the body 110 away from the receiving cavity 111. The plastic part 160 has a transparent or semi-transparent display area 161 that corresponds to the flashing element 150.

[0029] A plastic part 160 is covered on the outside of the mounting groove 1121 to seal the groove opening, which can completely prevent dust, liquid and other impurities from entering the receiving cavity 111; at the same time, the plastic part 160 has a transparent or semi-transparent display area 161 facing the flashing part 150, so that the light can pass through without obstruction and the flashing status is clear at a glance.

[0030] Please refer to Figure 3 The installation area 112 is also provided with a second magnetic groove 1122. The second magnetic groove 1122 and the installation groove 1121 are arranged in a straight line. The second magnetic component is disposed in the second magnetic groove 1122, and the plastic component 160 covers the side of the second magnetic groove 1122 away from the receiving cavity 111.

[0031] The second magnetic groove 1122 and the mounting groove 1121 can be simultaneously shielded by a single plastic part 160, reducing the number of parts and simplifying the assembly process. At the same time, it ensures the isolation and protection of the second magnetic part and the components inside the mounting groove 1121, improving the overall sealing performance and structural compactness.

[0032] Please refer to Figure 4 The phone case 100 also includes a switch assembly 170, which is disposed on the circuit board 130 and partially located in the mounting slot 1121. The flash element 150 and the switch assembly 170 are used to connect or disconnect the connection line between the NFC antenna 140 and the circuit board 130.

[0033] Since mobile phones also have NFC antennas, card readers are needed to identify NFC information on the phone for subway card payments, access card payments, credit card payments, and Apple Pay. However, because the phone case 100 also has an NFC antenna 140, the card reader may simultaneously identify two NFC signals, leading to a failure to recognize the signal. Therefore, in this situation, disconnecting the NFC antenna 140 of the phone case 100 from the circuit board 130 via the switch assembly 170 makes the NFC antenna 140 on the phone case 100 "invisible" in front of the card reader. When it is necessary to use the NFC antenna 140 to refresh the image on the electronic paper 120, the NFC antenna 140 on the phone case 100 is connected to the circuit board 130 via the switch assembly 170. The NFC antenna 140 receives the image information sent by the phone and transmits it to the circuit board 130, which then controls the electronic paper 120 to refresh the image.

[0034] Please refer to Figure 3-4 The second magnetic component, the flashing component 150, and the switch assembly 170 are arranged in a straight line.

[0035] The second magnetic component, the flashing component 150, and the switch assembly 170 are arranged in a straight line to maximize the compression of lateral space, which simplifies the mold, reduces the thickness, and makes the appearance more concise. At the same time, it facilitates unified wiring and one-step assembly, improving both yield and maintenance efficiency.

[0036] In some embodiments of this application, the switch assembly 170 includes a push button switch, a toggle switch, a capacitive switch, and a touch switch.

[0037] In addition, the switch assembly 170 in this embodiment is a push-button switch. A silicone part 190 is also provided in the mounting groove 1121 of this application at the position corresponding to the switch assembly 170. The silicone part 190 can improve the pressing feel of the switch assembly 170.

[0038] Please refer to Figure 1 The main body 110 is provided with a first magnetic groove 114 on the side opposite to the receiving cavity 111, and the first magnetic groove 114 protrudes from the main body 110, and the first magnetic member is disposed in the first magnetic groove 114.

[0039] The first magnetic groove 114 protrudes to form a "step" in which the first magnetic component is embedded. This not only improves the fit and attraction between the first magnetic component and the magnetic accessories, but also prevents the magnet from being directly exposed, making it scratch-resistant and wear-resistant, and giving it a neater overall shape.

[0040] In this application, the first magnetic element is a single-sided magnet.

[0041] The single-sided magnet is magnetic only on one side, so there is no need to distinguish between the front and back during assembly, and the installation can be completed in one step; at the same time, it effectively shields the magnetic field on the other side to avoid interference with the electronic paper 120, thus balancing convenience and reliability.

[0042] Please refer to Figure 2 The phone case 100 also includes a transparent element 180, which is disposed in the receiving cavity 111 and located between the display window 113 and the electronic paper 120, for the purpose of protecting the electronic paper 120.

[0043] The transparent component 180 is sandwiched between the display window 113 and the electronic paper 120, forming a rigid barrier that is scratch-proof and impact-proof without obstructing the image, ensuring that the electronic paper 120 remains clear and durable for a long time.

[0044] Please refer to Figure 3 The bottom of the receiving cavity 111 is also provided with a lens through groove 115. When the phone case 100 is put on the phone, the rear lens of the phone is located in the lens through groove 115.

[0045] Please refer to Figure 2 Along the length of the body 110, the mounting area 112 is located on the side of the first magnetic member away from the lens through groove 115.

[0046] The installation area 112 is positioned on the side away from the lens slot 115, resulting in less blank space at the bottom of the phone case 100 and optimizing the overall proportions and grip.

[0047] In this application, the mounting groove 1121 protrudes on the side of the body 110 away from the receiving cavity 111, making it convenient for the user to press the switch assembly 170.

[0048] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
