[0002] In recent years, to meet users' demands for personalized and functionally expanded phone cases, phone cases with integrated e-ink screens have gradually become a market trend. These products allow users to customize displayed patterns, real-time information, or dynamic interfaces by embedding an electronic screen (such as an e-ink screen or OLED screen) on the back of the phone case.

[0003] However, while such designs enhance the user experience, they also raise new structural compatibility issues, particularly the tendency to interfere with the stand on the back of the phone. Existing e-ink phone cases typically center the display module to maximize the visible area, while mainstream folding stands also need to occupy the center or lower-middle area of ​​the back of the phone. The overlapping layout of the two prevents users from using the screen display and stand functions simultaneously, or forces the stand to be installed at the edge, resulting in unstable device support. Therefore, improvements are urgently needed. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. In addition, the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0024] To address the technical deficiencies in related technologies, this utility model provides a mobile phone case. Please refer to [link / reference]. Figures 1 to 4 The phone case includes: a housing 100, an e-ink screen 200, a bracket 300, and a cover plate 500. The housing 100 has a first mounting groove 110 and a second mounting groove 120 arranged opposite to each other. The first mounting groove 110 is adapted to an external mobile phone, allowing the mobile phone to be installed on the housing 100. The housing 100 can fully cover the mobile phone or partially cover it. The housing 100 can be made of soft silicone or a harder plastic material. The specific form of covering the mobile phone and the specific material used by the housing 100 are not limited here.

[0025] The e-ink screen 200 is installed in the second mounting slot 120 and can communicate with an external mobile phone. The installation method of the e-ink screen 200 in the second mounting slot 120 can be adhesive, snap-fit ​​or other installation methods, which are not specifically limited here.

[0026] The cover plate 500 is connected to the housing 100 and encloses the e-ink screen 200 within the second mounting groove 120. The bracket 300 is rotatably mounted on the cover plate 500 and has a retracted state flush with the surface of the cover plate 500 and a working state protruding from the surface of the cover plate 500. The bracket 300 is ring-shaped. When the bracket 300 is in the retracted state, the e-ink screen 200 is located inside the bracket 300. When the user needs to use the bracket 300 to support the phone, the bracket 300 can be manually rotated so that the bracket 300 protrudes from the surface of the cover plate 500. At this time, one end of the bracket 300 is connected to the housing 100, and the other end of the bracket 300 can abut against the table. Thus, the phone can be placed at an angle on the table under the action of the bracket 300.

[0027] In addition, the stand 300 is arranged in a ring shape. When the stand 300 is in the retracted state, the e-ink screen 200 is located inside the stand 300. In this way, the e-ink screen 200 is located inside the stand 300, and its layout does not interfere with the stand 300. The stand 300 will not affect the display effect of the e-ink screen 200.

[0028] It should be noted that the bracket 300 can be arranged in a circular ring shape, a square ring shape, or other ring shapes, without any specific limitation here.

[0029] Through the above technical solution, the phone case bracket 300 is rotatably mounted on the surface of the housing 100. The bracket 300 is arranged in a ring shape, which means that when the bracket 300 is in the storage state and flush with the surface of the housing 100, there is a space inside the bracket 300, in which the e-ink screen 200 is installed. In this way, the phone case bracket 300 will not interfere with the e-ink screen 200, the structural space design is compact, and the overall appearance of the phone case is improved.

[0030] Considering that the e-ink screen 200 needs a power source to display images and interact with the mobile phone, in order to facilitate the phone case to provide power to the e-ink screen 200, in this embodiment, the phone case also includes a near-field communication panel 400. The near-field communication panel 400 is installed in the second mounting slot 120, and the near-field communication panel 400 draws power from the external mobile phone and is electrically connected to the e-ink screen 200.

[0031] Near Field Communication (NFC) is a short-range, high-frequency radio technology that allows electronic devices to perform contactless point-to-point data transmission over very short distances and to exchange power. In this embodiment, when a mobile phone is in close contact with the NFC panel 400, the smartphone emits radio signals, creating an electromagnetic field. The NFC panel 400 then senses the energy in the electromagnetic field through its receiving coil and converts it into electrical energy to power itself. This configuration allows the NFC panel 400 to transmit power without a physical connection interface and also provides power to the e-ink screen 200, greatly improving the ease of use of the phone case.

[0032] It should be noted that the near-field communication panel 400 not only has power exchange function, but can also be designed to accommodate electronic access card function as needed, so that the mobile phone case has electronic access card function, which can increase the usage scenarios and make it more convenient for users.

[0033] To facilitate the rotational mounting of the bracket 300 onto the surface of the housing 100, in this embodiment, the bracket 300 includes a fixed frame 310 and a rotating frame 320. The fixed frame 310 is connected to the surface of the housing 100, and the rotating frame 320 is rotatably connected to the fixed frame 310. Both the fixed frame 310 and the rotating frame 320 are arranged in a ring shape, with the e-ink screen 200 located inside the fixed frame 310. Since the e-ink screen 200 is located inside the fixed frame 310, the fixed frame 310 can also protect the e-ink screen 200, providing protection when the phone is dropped.

[0034] In some embodiments, the mounting bracket 310 is rotatably connected to the housing 100, and the axis of rotation of the mounting bracket 310 is perpendicular to the surface of the housing 100. The mounting bracket 310 can rotate relative to the housing 100, and the user can rotate it to a suitable position as needed, then pull out the rotating bracket 320 to support the mobile phone, making it convenient for the user to adjust according to their own needs.

[0035] In addition, an annular rib 130 is provided on the surface of the housing 100, and the fixing frame 310 is rotatably installed in the annular rib 130. The outer edge of the fixing frame 310 is clearance-fitted with the inner edge of the annular rib 130, so that the fixing frame 310 can rotate relative to the housing 100.

[0036] To enhance the overall aesthetics of the phone case, in some embodiments, the mounting bracket 310 and the rotating bracket 320 are arranged in a circular ring shape, and the e-ink screen 200 is also arranged in a circular shape. The circular shape of the e-ink screen 200 and the ring-shaped bracket 300 can improve the coordination with the arrangement of the phone's camera module, thus enhancing the overall aesthetics.

[0037] To facilitate users in flipping and rotating the stand 320 to support their mobile phones, in some embodiments, a handle 321 is provided on the outer edge of the stand 320. Users can use their fingers to press the handle 321 to change the stand 300 from a stored state to a usable state.

[0038] Additionally, in some embodiments, the phone case also includes a lens (600) covering the e-ink screen (200), the lens (600) being located inside the mounting bracket (310), and the surface of the lens (600) being flush with the surface of the mounting bracket (310). This ensures that the e-ink screen (200) located in the second mounting slot (120) can display the image.

[0039] Ink capsule molecules within the e-ink screen 200 are propelled to different positions by the control of positive and negative charges. When the current stops, the ink capsule molecules remain fixed in their current positions. With this configuration, the display of the e-ink screen 200 does not require power, significantly reducing the energy consumption of the e-ink screen 200. To facilitate the rotation of the rotating frame 320 relative to the fixed frame 310, in this embodiment, the support 300 is equipped with a hinge. One end of the hinge is connected to the fixed frame 310, and the other end is connected to the rotating frame 320. The rotation axis 330 of the hinge is located on the periphery of the support 300.

[0040] In addition, the cover plate 500 is provided with a through hole 510 at the position of the e-ink screen 200. The rotating shaft 330 can move along the periphery of the through hole 510. The through hole 510 is used to expose the e-ink screen 200. The connection method between the cover plate 500 and the housing 100 can be adhesive bonding, ultrasonic welding or other connection methods, which are not specifically limited here.
