[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this utility model, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] In existing technologies, the continuous increase in the frequency of mobile device use has led to a growing demand from users for comfortable grip. Traditional phone stands mostly adopt a fixed ring structure, and their surface patterns or decorations cannot be changed after manufacturing, preventing users from adjusting the displayed content according to usage scenarios or personal preferences. When users need to display dynamic information or make personalized settings, such products lack effective interaction methods and display update capabilities, resulting in a technical deficiency of limited functionality.

[0023] To address the aforementioned issues, researchers noted the low-power display characteristics of e-ink screens and discovered that near-field communication (NFC) technology can both transmit data and acquire energy. By analyzing the feasibility of integrating the support structure with electronic components, they proposed combining a ring-shaped support structure with the display module, utilizing the principle of electromagnetic induction to achieve passive power supply. The research focused on resolving key technical challenges such as display module installation and positioning, wireless communication component layout, and the coordinated operation of the rotation mechanism and electronic components, resulting in a smart support solution with self-updating capabilities.

[0024] Please refer to the following: Figures 1 to 3This utility model embodiment proposes a mobile phone stand with an e-ink screen 4, which includes a ring-shaped bracket 1, a bottom cover 2, a ring buckle 3, an e-ink screen 4, and a circuit board 5. The bottom cover 2 is disposed on the bottom surface of the ring-shaped bracket 1. The ring buckle 3 is rotatably connected to the ring-shaped bracket 1 and complementarily cooperates with the inner ring of the ring-shaped bracket 1. The e-ink screen 4 is mounted on the ring-shaped bracket 1 and located on one side of the bottom cover 2, with the display area of ​​the e-ink screen 4 exposed in the inner ring area of ​​the ring-shaped bracket 1. The circuit board 5 is mounted inside the ring-shaped bracket 1, and the front of the circuit board 5 is provided with an NFC antenna (not shown in the figure) and an NFC module 51. The two ends of the NFC module 51 are electrically connected to the NFC antenna and the e-ink screen 4, respectively. The NFC module 51 interacts with the mobile phone and obtains power through the NFC antenna.

[0025] The components are as follows: Ring bracket 1 refers to a support frame with a ring-shaped body structure, which can be manufactured using injection molding to create a ring-shaped cavity structure. It supports electronic components and provides mechanical support. Bottom cover 2 refers to a closed component covering the bottom of ring bracket 1, which can be implemented using a snap-on plastic cover, forming the mounting base for the e-ink screen 4. Ring buckle 3 refers to a rotatable support component, which can be implemented using a metal shaft connected to the inner ring sidewall of ring bracket 1. Its arc-shaped contour complements the inner ring of the bracket. E-ink screen 4 refers to an electronic ink display device, which can be implemented using a flexible electronic paper display screen. Its display area is exposed outward through the opening in the inner ring of ring bracket 1, capable of displaying static personalized patterns and information. It does not require continuous power supply; it only needs to obtain power when changing patterns and information to continuously display the current pattern and information. Circuit board 5 refers to a printed circuit board 5 integrating electronic components, which can be implemented using a multi-layer printed circuit board. NFC antenna refers to a near-field communication coil, which can be implemented using etched copper foil to form a ring circuit, generating electromagnetic coupling with the mobile terminal for energy transfer. NFC module 51 refers to the near field communication control chip, which can be implemented using an integrated NFC controller to convert the received display data into driving signals for the e-ink screen 4.

[0026] Specifically, when the mobile terminal approaches the ring bracket 1, the NFC antenna obtains electrical energy through electromagnetic induction and powers the circuit board 5. The NFC module 51 receives display data sent by the terminal, processes it, and drives the e-ink screen 4 to update the screen content. After the ring buckle 3 rotates and unfolds around the pivot, its arc-shaped support surface forms a stable support structure with the inner ring of the bracket. The display area of ​​the e-ink screen 4 displays personalized patterns and static information through the ring opening, and the sandwich structure formed by the bottom cover 2 and the ring bracket 1 fixes the position of the display screen. The compact layout of the circuit board 5 within the ring cavity ensures that the communication components and mechanical structure do not interfere with each other.

[0027] Compared to existing technologies, traditional stands only provide physical support, and the displayed content is fixed and cannot be changed. This embodiment of the invention integrates an e-ink screen 4 to achieve personalized patterns and static information updates, and utilizes NFC technology to simultaneously complete data transmission and power acquisition, eliminating the need for a separate power supply. The ring-shaped stand 1 integrates the display module and communication components within a limited space, resulting in a compact design that does not increase the overall thickness of the stand.

[0028] Through the above technical solutions, this utility model embodiment enables the mobile phone holder to display personalized patterns and static information. Users can wirelessly update personalized patterns and static information through mobile terminals. NFC communication provides power supply simultaneously when transmitting data, avoiding the need for additional charging interfaces. The integrated design of the ring support structure and electronic components ensures the reliable operation of electronic functions while maintaining structural strength. The complementary cooperation between the ring buckle 3 and the holder ensures the stability of the support in the unfolded state and the space utilization rate when stored.

[0029] For example, the mobile phone holder with e-ink screen 4 proposed in this embodiment of the present invention also includes a magnet assembly 6, which is installed inside the annular bracket 1.

[0030] It is understood that the magnet component 6 refers to an adsorption device made of magnetic material, specifically a permanent magnet. The magnet component 6 is integrated into the internal cavity of the annular bracket 1. When the electronic device approaches the bracket, the magnetic field generated by the magnet component 6 forms a magnetic coupling with the metal backplate of the device. This adsorption method achieves device fixation without mechanical clips or clamping structures. During operation, simply bringing the device close to the bracket will automatically adsorb and position it; separation is achieved by applying a slight external force. The built-in layout of the magnet component 6 avoids external protruding structures, and the surface of the annular bracket 1 remains flat, achieving a stable connection without affecting the grip. Therefore, this embodiment of the invention solves the problems of unstable fixation and inconvenient assembly / disassembly of mobile phone holders and electronic devices through the design of the magnet component 6. The magnetic connection method eliminates the need for precise alignment during device fixation, improving the efficiency of assembly / disassembly operations. Furthermore, the built-in magnet component 6 ensures sufficient adsorption force while avoiding interference from external structures, preventing any discomfort when holding the device, and ensuring that the contact surface between the bracket and the device remains flat.

[0031] Furthermore, the annular bracket 1 is provided with an annular chamber, which is divided into a first mounting cavity 11 and a second mounting cavity 12 by a partition 14. The magnet assembly 6 is installed in the first mounting cavity 11, and the circuit board 5 is installed in the second mounting cavity 12.

[0032] Understandably, the annular chamber is divided into two independent spaces by the partition 14. The magnet assembly 6 is confined within the first mounting cavity 11, and the circuit board 5 is confined within the second mounting cavity 12. Through physical isolation, the magnetic field generated by the magnet assembly 6 is limited to a local area, avoiding electromagnetic interference to the NFC module 51 and electronic components on the circuit board 5, thus improving the stability of NFC communication. The rigid support structure formed by the partition 14 enhances the mechanical strength of the annular bracket 1, while providing independent mounting reference surfaces for the magnet assembly 6 and the circuit board 5, avoiding positioning deviations caused by spatial overlap during installation, thereby improving product reliability and service life.

[0033] Furthermore, the first mounting cavity 11 occupies 7 / 8 of the entire annular cavity, and the magnet assembly 6 complements the first mounting cavity 11.

[0034] Understandably, after the annular chamber is divided into a 7:1 spatial ratio, the magnet assembly 6 is completely housed within the larger chamber, its volume matching the chamber space to ensure the stability of the magnetic attraction. The remaining chamber independently houses the circuit board 5, with physical isolation between the two achieved through partitions to prevent the magnetic field generated by the magnet assembly 6 from interfering with the circuit board 5. The complementary fit between the magnet assembly 6 and the inner wall of the chamber prevents the assembly from shifting or deflecting when the support rotates or is subjected to external impact, thus maintaining the stability of the overall structure.

[0035] Furthermore, the magnet assembly 6 includes an upper magnet 61, a middle iron sheet 62, and a lower magnet 63 arranged sequentially from top to bottom.

[0036] Understandably, the upper magnet 61 and the lower magnet 63 can be implemented using neodymium iron boron magnets. When a highly conductive iron sheet 62 (usually low-carbon steel, electrical pure iron, etc.) is sandwiched between the two magnets, the middle iron sheet 62 can efficiently converge and guide magnetic lines of force. Furthermore, the middle iron sheet 62 itself will be strongly magnetized by the upper and lower magnets, forming a magnetic circuit with a larger and more concentrated magnetic flux. As a result, the magnetic field strength (magnetic induction intensity) of the entire composite magnet assembly 6 is significantly improved to the outside (especially towards the outside, i.e., the upper surface of the upper magnet 61 and the lower surface of the lower magnet 63), thereby greatly enhancing the attraction force on the iron sheet / steel plate on the back of the phone and ensuring that the phone remains stable and does not fall. In addition, the middle iron plate 62 acts as a rigid connecting plate between the upper and lower magnets. It fixes the relative position of the upper and lower magnets, preventing them from being misaligned or rotated when subjected to lateral force or torsion. At the same time, it increases the overall rigidity and strength of the entire component, making it less prone to deformation or breakage, thereby improving the structural stability and service life of the ring buckle 3 when it is opened, rotated, or when the mobile phone is accidentally hit.

[0037] For example, the mobile phone stand with e-ink screen 4 proposed in this embodiment of the present invention also includes a pivot bracket 7, which is fixedly installed in the second mounting cavity 12 by screws and is rotatably connected to the ring buckle 3.

[0038] It is understood that the rotating shaft bracket 7 refers to a support component with a shaft structure, which can be made of die-cast aluminum alloy, and is used to support the rotational movement of the ring buckle 3. After the rotating shaft bracket 7 is assembled into the second mounting cavity 12, it is fixed by screws passing through the mounting holes on the rotating shaft bracket 7 and the pre-set studs in the cavity. At this time, the axis of the rotating shaft bracket 7 remains parallel to the plane of the annular bracket 1. The ring buckle 3 is sleeved on the shaft of the rotating shaft bracket 7 through the shaft hole at its end, and the limiting retaining rings at both ends of the shaft prevent axial displacement. When an external force is applied to the ring buckle 3, the torque borne by the rotating shaft bracket 7 is transmitted to the cavity wall of the second mounting cavity 12 through the screws, and the clearance fit between the rotating shaft and the shaft hole allows the ring buckle 3 to rotate around the shaft. Therefore, the combination of the rotating shaft bracket 7 and the screw fixation effectively disperses the stress during the rotation process, realizing both the rotation function and ensuring connection stability; the screw connection method allows the rotating shaft bracket 7 to be replaced separately, providing convenience for later maintenance; the design of the rotating shaft bracket 7 and the second mounting cavity 12, compared with the solution of directly embedding the rotating shaft into the plastic bracket, effectively prevents the deformation problem caused by long-term stress on the plastic parts.

[0039] Furthermore, the circuit board 5 rests against the bottom surface of the rotating shaft bracket 7 and is fixedly mounted on the rotating shaft bracket 7 by screws.

[0040] It is understandable that back-to-back mounting refers to an assembly method in which the circuit board 5 and the bottom surface of the hinge bracket 7 form surface contact. Specifically, this can be achieved by using a combination of flat surface fitting and positioning post alignment. This method utilizes the rigid structure of the hinge bracket 7 to provide a uniform support surface for the circuit board 5. After the circuit board 5 is positioned on the bottom surface of the hinge bracket 7, its mounting holes are aligned with the threaded holes of the hinge bracket 7. Countersunk screws are screwed into the threaded holes through the mounting holes to complete the fastening, thereby restricting the displacement of the circuit board 5 in three-dimensional space and ensuring that the electrical connection between the NFC module 51 on the circuit board 5 and the e-ink screen 4 is not affected by the rotation of the ring buckle 3.

[0041] For example, the inner ring of the ring bracket 1 is provided with a groove 13 near the bottom cover 2, which can match the shape of the e-ink screen 4, and a sandwich layer is formed between the bottom cover 2 and the groove 13 to clamp the e-ink screen 4.

[0042] It is understandable that the groove 13 refers to a recessed structure that perfectly matches the geometric shape of the edge of the e-ink screen 4. This can be achieved through injection molding, and its function is to provide circumferential restraint for the e-ink screen 4. After the e-ink screen 4 is embedded in the groove 13, its edge forms surface contact with the groove 13, thereby achieving lateral displacement constraint. During assembly, the inner surface of the bottom cover 2 covers the opening end face of the groove 13, so that the bottom surface of the groove 13 and the inner surface of the bottom cover 2 together form a bidirectional clamping effect on the e-ink screen 4. This sandwich structure utilizes the frictional force of the contact surfaces to offset external impacts, effectively preventing the e-ink screen 4 from shifting or falling off when the bracket is subjected to external impacts. This ensures that the display area is always exposed within the inner ring of the annular bracket 1, solving the technical problem of display offset caused by poor screen installation stability.

[0043] For example, a cotton pad 8 is provided between the bottom cover 2 and the ink screen 4.

[0044] It is understood that the cotton pad 8 refers to a flexible filler with elastic compression properties, which can be implemented using polyurethane foam or silicone sponge materials. When the bottom cover 2 is locked with the annular bracket 1, the cotton pad 8 undergoes elastic deformation in the vertical direction, absorbing the axial pressure generated during the locking process and avoiding surface scratches and internal liquid crystal layer damage caused by rigid contact. In the lateral dimension, the cotton pad 8 fills the assembly tolerance between the inner surface of the bottom cover 2 and the outer edge of the e-ink screen 4 through lateral expansion, eliminating the shaking phenomenon caused by component processing errors and solving the screen displacement problem caused by assembly gaps. In addition, when external impact loads are applied to the bottom cover 2, the porous structure of the cotton pad 8 dissipates energy through compression deformation.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
