[0002] Currently, with the increasing demand for personalized mobile phone accessories, mobile phone cases with integrated display functions are gradually appearing on the market. These cases achieve information visualization by embedding electronic displays (such as LED dot matrix screens, e-ink screens, etc.) on the back of the case.

[0003] However, existing e-ink screens on phone cases with integrated screens are generally square in shape. The large size of the square e-ink screen leads to higher overall power consumption. In addition, there is a space conflict between the edges of the square e-ink screen and the installation position of the magnetic bracket (usually circular), which requires reserving a non-display area to avoid the magnetic structure. This further reduces the effective display area of ​​the e-ink screen, resulting in poor overall aesthetic compatibility. Moreover, the square e-ink screen lacks coordination with the arrangement of the phone's camera module, resulting in a visual disjointed feeling and limiting its acceptance in the high-end market. Therefore, improvements are urgently needed. Utility Model Content

[0027] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0028] To address the technical deficiencies in related technologies, this utility model provides a phone case with a screen. Please refer to [link / reference]. Figs. 1 to 4 The screen-equipped phone case includes: a housing 100, an e-ink screen 200, an arc-shaped magnetic sheet 300, and a cover plate 400. The housing 100 has a mounting cavity 110 adapted to the phone and a first mounting groove 120 disposed opposite to the mounting cavity 110. The mounting cavity 110 is used to adapt to the phone so that the phone can be installed on the housing 100. The housing 100 can fully cover the 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 phone and the specific material used by the housing 100 are not limited here.

[0029] The e-ink screen 200 is circular in shape and is disposed in the first mounting slot 120. The e-ink screen 200 can communicate with external devices. The communication connection between the e-ink screen 200 and external devices allows users to display corresponding images according to their own needs. Specifically, in this embodiment, the e-ink screen 200 communicates with a mobile phone that is compatible with the phone case.

[0030] The arc-shaped magnetic sheet 300 is set in the first mounting groove 120 and located on the outer periphery of the e-ink screen 200. This arrangement ensures that the magnetic structure of the phone case and the e-ink screen 200 do not interfere with each other in terms of spatial layout, thereby improving the overall space utilization of the case 100. While ensuring that the e-ink screen 200 displays personalized functions, it also takes into account the magnetic function of the phone, meeting the diverse usage needs of users.

[0031] To prevent the e-ink screen 200 from detaching from the curved magnetic sheet 300 in the first mounting groove 120, the screen-equipped mobile phone case in this embodiment is also provided with a cover plate 400. The cover plate 400 is connected to the housing 100 and covers the first mounting groove 120. The cover plate 400 is provided with a viewing area 410 located above the e-ink screen 200. The viewing area 410 is light-transmitting so that the e-ink screen 200 can display the pattern.

[0032] Through the above technical solution, the screen phone case of this embodiment uses a circular e-ink screen 200, and an arc-shaped magnetic sheet 300 is set around the e-ink screen 200, so that the e-ink screen 200 and the arc-shaped magnetic sheet 300 can be arranged compactly, with high space utilization. The phone case of this technical solution can not only allow users to display personalized e-ink screens 200, but also take into account the magnetic function of the phone case. In addition, the circular e-ink screen 200 and the mobile phone camera module form an aesthetic echo, which also enhances the product's recognizability and makes the overall aesthetic adaptability of the phone case high.

[0033] Considering that the e-ink screen 200 needs to be powered when displaying images and interacting with external devices, in order to facilitate the phone case to provide power to the e-ink screen 200, in this embodiment, the phone case with screen also includes an NFC board 500. The NFC board 500 is disposed in the first mounting slot 120. The NFC board 500 draws power from the phone adapted to the case 100 through radio magnetic field transmission. The NFC board 500 is electrically connected to the e-ink screen 200.

[0034] 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 smartphone is in close contact with the NFC board 500, the smartphone emits a radio signal, forming an electromagnetic field. The NFC board 500 then senses the energy in the electromagnetic field through its receiving coil and converts it into electrical energy to power itself. With this configuration, the NFC board 500 in this embodiment can achieve power transmission without a physical connection interface, and it can also provide power to the e-ink screen 200, greatly improving the ease of use of the screen-equipped phone case.

[0035] It should be noted that the NFC board 500 not only has power exchange function, but can also be designed to accommodate electronic access card function according to needs, so that the screen phone case has NFC electronic access card function, which can increase the usage scenarios and make it more convenient for users.

[0036] In some embodiments, the screen-equipped phone case further includes a circuit board 510, which is electrically connected to the NFC board 500 and the e-ink screen 200. The circuit board 510 receives data transmitted from the NFC board 500, processes the data transmission, and displays it on the e-ink screen 200.

[0037] In the e-ink display 200, ink capsule molecules are propelled to different positions by the control of positive and negative charges. Under the control of the circuit board 510, when the current stops, the ink capsule molecules remain fixed in their current positions. With this configuration, the display of the e-ink display 200 does not require power, significantly reducing the energy consumption of the e-ink display 200.

[0038] In addition, the NFC board 500 is located near the edge of the housing 100. In general, the antenna of a smartphone is located on the side of the phone. The NFC board 500 is located at the edge of the housing 100, which makes it easy to draw power. Moreover, when the NFC board 500 is used as an electronic access card, the NFC board 500 located at the edge of the housing 100 makes it more convenient for users to swipe the card.

[0039] Considering that the curved magnetic sheet 300 is generally located in the middle of the phone case, making it convenient for the phone to be attached to the magnetic bracket, in some embodiments, the e-ink screen 200 is located in the center of the first mounting groove 120. Thus, the curved magnetic sheet 300 is also located in the middle of the housing 100, ensuring that the phone case with the screen can be attached to the magnetic bracket at any angle of 360 degrees and is not prone to tilting.

[0040] To facilitate the placement of the e-ink screen 200 and the curved magnetic sheet 300 within the first mounting groove 120, in some embodiments, the screen-equipped phone case further includes a mounting plate 600. The mounting plate 600 is disposed within the first mounting groove 120 and has a second mounting groove 610 and a third mounting groove 620. The second mounting groove 610 is adapted to the outer contour of the e-ink screen 200 for mounting the e-ink screen 200, and the third mounting groove 620 is adapted to the outer contour of the curved magnetic sheet 300 for mounting the curved magnetic sheet 300.

[0041] In some embodiments, two arc-shaped magnetic sheets 300 are provided, and the two arc-shaped magnetic sheets 300 are arranged at intervals along the periphery of the e-ink screen 200. The two arc-shaped magnetic sheets 300 can increase the magnetic attraction force and ensure that the magnetic bracket can stably attract the mobile phone.

[0042] Considering that the screen-equipped phone case is made of soft material, while the curved magnetic sheet 300 is made of harder material, the curved magnetic sheet 300 may break due to impact when the case 100 is twisted or when the screen-equipped phone case containing the phone is dropped. Therefore, to prevent the curved magnetic sheet 300 from breaking, in some embodiments, the curved magnetic sheet 300 includes multiple curved small magnetic blocks 310, which are connected end-to-end to form the curved magnetic sheet 300. The curved magnetic sheet 300 formed by the multiple curved small magnetic blocks 310 perfectly matches the outer edge curvature of the circular e-ink screen 200. Through the continuous splicing of multiple independent curved small magnetic blocks 310, a closed magnetic ring concentrically distributed with the e-ink screen 200 is formed, eliminating the magnetic field distortion problem at the circular edge of the traditional rectangular magnetic sheet.

[0043] In some embodiments, the diameter of the e-ink screen 200 is set to be less than or equal to 42mm. Generally, the inner diameter of the magnetic bracket on the market is 42mm. Setting the diameter of the e-ink screen 200 to be less than or equal to 42mm can make it compatible with magnetic brackets on the market.

[0044] In addition, the cover plate 400 and the housing 100 are connected by ultrasonic welding. The cover plate 400 is provided with a viewing area 410 located above the e-ink screen 200, which encloses the NFC board 500, the circuit board 510 and the e-ink screen 200 in the first mounting groove 120, making the overall housing 100 simple.

[0045] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
