Description

Technical Field

[0001] This utility model relates to the field of mobile terminal accessories technology, and in particular to an e-ink screen anti-loss magnetic bracket card holder. Background Technology

[0002] With the continuous development of mobile terminal accessories, magnetic card holders have become widely used because they can be attached to the back of mobile phones or phone cases and used to store flat items such as bank cards and access cards. To improve the functionality of magnetic card holders, existing products are further equipped with display modules, anti-loss modules, or support structures, enabling them to be used for image display, location finding, and supporting mobile terminals.

[0003] Existing magnetic card holders with display functions typically require a display structure integrated into the main body of the holder, while the holder itself needs to attach to a mobile device via a magnetic connection. When the placement of the display structure and the magnetic connection is inappropriate, the display area can easily be obstructed by the mobile device, preventing the displayed content from being properly shown. If the display structure is placed elsewhere to avoid the magnetic connection area, it can easily reduce the card storage space inside the holder or increase the overall size and thickness of the holder.

[0004] Furthermore, existing magnetic card holders typically require additional support plates, feet, or other deployable support components to support mobile devices. This independent support structure not only increases the number of parts and assembly complexity but also tends to increase the number of structural layers and overall thickness of the magnetic card holder, making it difficult to carry with mobile devices. Especially when a magnetic card holder integrates card storage, information display, and mobile device support, space occupancy and structural interference between these functional structures can easily occur, making it difficult to balance the exposure of displayed content, the fulfillment of support functions, and the product's slim and portable design.

[0005] Therefore, a magnetic holder for preventing loss of e-ink screens is proposed to solve the above problems. Utility Model Content

[0006] The main purpose of this utility model is to provide a magnetic holder for preventing the loss of an ink screen; In order to achieve the above-mentioned utility model objectives, this utility model proposes an ink screen anti-loss magnetic bracket card holder, including a first shell and a receiving part for accommodating cards; The second housing is hinged to the first housing; A magnet, disposed within the second housing, is used to connect an external device to the second housing; A display component is disposed within the second housing, with the display surface of the display component and the magnetic attraction surface of the magnet located on opposite sides of the second housing, respectively.

The first housing is used to support the second housing and external devices that are magnetically connected to the second housing.

[0007] Furthermore, the first housing is provided with a first hinge portion, and the second housing is provided with a second hinge portion, and the first hinge portion and the second hinge portion are rotatably connected by a rotating shaft.

[0008] Furthermore, the display component includes an e-ink screen and a display cover plate disposed on the display side of the e-ink screen, and the second housing is provided with a display window corresponding to the display area of ​​the e-ink screen.

[0009] Furthermore, the first housing has a storage side and a display side arranged opposite to each other, the receiving part is provided on the storage side, and the display side is provided with a mounting groove for accommodating the sheet-like display piece.

[0010] Furthermore, the magnet is in the shape of a non-closed ring, and the projection of the display area of ​​the display component in the thickness direction of the second housing is at least partially located within the area enclosed by the magnet in the circumferential direction.

[0011] Furthermore, a coil is also provided inside the second housing, the magnet is arranged circumferentially along the coil, the coil has a power receiving end, the second housing is provided with a clearance hole corresponding to the power receiving end, the power receiving end passes through the clearance hole and is electrically connected to the control component.

[0012] Furthermore, the second housing is provided with a receiving groove for mounting the magnet and a positioning groove for mounting the coil.

The Bluetooth communication module is used to establish a wireless communication connection with the external device and receive image data sent by the external device. The positioning module is used to provide the location information of the e-ink screen anti-loss magnetic bracket card holder.

[0014] Furthermore, the wireless communication component includes a StarFlash communication module, which is used to establish a wireless communication connection with the external device and to realize data transmission and anti-loss reminders.

[0015] Furthermore, the second housing is provided with a switch button, which is electrically connected to the control component and is used to control the display component to turn on or off. Beneficial effects

[0016] This invention achieves card storage and external device support simultaneously by hinged a first housing with a receiving portion to a second housing. When the first housing is unfolded relative to the second housing, an angle is formed between them. This allows the first housing to hold cards while supporting the second housing and an external device magnetically connected to it, eliminating the need for a separate support component. Furthermore, by positioning the display surface of the display component and the magnetic surface of the magnet on opposite sides of the second housing, the display component can still face outwards after the second housing is magnetically connected to the external device, preventing obstruction of the displayed content.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1 to 8 As shown, this embodiment provides an e-ink screen anti-loss magnetic bracket card holder. This e-ink screen anti-loss magnetic bracket card holder can be magnetically connected to a mobile phone, mobile phone case or other external devices, and can realize functions such as card storage, image display, wireless communication, location acquisition, anti-loss reminder and external device support.

[0023] The e-ink screen anti-loss magnetic holder package includes a first housing 10, a second housing 20, a magnet 30, a display component 40, a control component 50, and a wireless communication component.

[0024] The first housing 10 is provided with a receiving part 11 for accommodating cards. The receiving part 11 is formed inside the first housing 10 for placing bank cards, access cards, identity cards or other flat cards. The first housing 10 has a plate-like structure, so that the first housing 10 can be used as a card storage structure and as a support structure after being unfolded relative to the second housing 20.

[0025] The receiving part 11 is provided with a card insertion slot 16 communicating with it. Cards can be inserted into or removed from the receiving part 11 through the card insertion slot 16. When the first housing 10 and the second housing 20 are closed together and the second housing 20 is magnetically connected to the back of the external device, when the external device is in a vertical use state, the card insertion slot 16 is located on the upper side of the first housing 10, so that the card can be inserted into the receiving part 11 from top to bottom. This makes it convenient for the user to pick up and put away the card, and at the same time, the card tends to move towards the inside of the receiving part 11 under its own weight, reducing the possibility that the card will slide out or fall off through the card insertion slot 16 during carrying or use.

[0026] The first housing 10 has a storage side 12 and a display side 13 arranged opposite to each other. The receiving part 11 is provided on the storage side 12 of the first housing 10. The display side 13 of the first housing 10 is provided with a mounting groove 14 for accommodating a sheet-like display piece. The sheet-like display piece can be a paper photo, a paper card, or other sheet-like display. In this embodiment, the sheet-like display piece is a paper photo, so that the first housing 10 can be used to place and display paper photos while storing cards.

[0027] The second housing 20 is hinged to the first housing 10 so that the first housing 10 can rotate relative to the second housing 20. The magnet 30, the display component 40, the control component 50, and the wireless communication component are all disposed inside the second housing 20. The two opposite sides of the second housing 20 are provided with a plurality of spaced grooves 60. The plurality of grooves 60 are distributed around the periphery of the second housing 20 and in areas that avoid the installation positions of the main functional components. Intersecting rib-like connecting parts are retained between adjacent grooves 60, thereby reducing the amount of material used in the second housing 20 while forming a grid-like support structure.

[0028] By providing multiple grooves 60 on opposite sides of the second housing 20, the amount of material used in the second housing 20 can be reduced and its own weight can be lowered. This reduces the additional burden on the e-ink screen anti-loss magnetic bracket wallet when carried with external devices, and reduces the load on the magnetic connection position and the hinge position between the first housing 10 and the second housing 20 when the bracket is in use. This helps to improve the lightweight and portability of the e-ink screen anti-loss magnetic bracket wallet.

[0029] The rib-like connecting parts formed between adjacent grooves 60 can also strengthen the structure of the second housing 20, improve the bending and torsional resistance of the second housing 20, and make the second housing 20 less prone to bending or torsional deformation when magnetically connecting or supporting external devices. This helps to maintain the flat and close fit between the magnetic surface of the magnet 30 and the external device, and reduces the occurrence of local warping, uneven magnetic attraction, or decreased magnetic connection stability caused by deformation of the second housing 20.

[0030] The first housing 10 is provided with a first hinge portion 15, and the second housing 20 is provided with a second hinge portion 24. The first hinge portion 15 and the second hinge portion 24 are rotatably connected by a rotating shaft 70. Specifically, the first hinge portion 15 and the second hinge portion 24 are arranged correspondingly to each other, and the rotating shaft 70 cooperates with the first hinge portion 15 and the second hinge portion 24 respectively, so that the first housing 10 can be unfolded or retracted relative to the second housing 20 with the rotating shaft 70 as the rotation center.

[0031] When the first housing 10 is folded up relative to the second housing 20, the first housing 10 and the second housing 20 move closer to each other, making the overall e-ink screen anti-loss magnetic bracket card case relatively flat, thereby reducing the space occupied by the e-ink screen anti-loss magnetic bracket card case in the storage state and making it easier for the e-ink screen anti-loss magnetic bracket card case to be carried with external devices.

[0032] When the first housing 10 is unfolded relative to the second housing 20, an angle is formed between the first housing 10 and the second housing 20. The first housing 10 can serve as a support to support the second housing 20 and external devices that are magnetically connected to the second housing 20, so that the external devices are kept in an inclined state relative to the desktop or other bearing surface.

[0033] Depending on the placement of the first housing 10 and the second housing 20 relative to the bearing surface, the e-ink screen anti-loss magnetic bracket wallet can form a first usage state and a second usage state. In the first usage state, one side of the first housing 10 is placed on the bearing surface, and the second housing 20 is extended upward relative to the first housing 10. The first housing 10 serves as a bottom support structure to support the second housing 20 and the external device magnetically connected to the second housing 20, keeping the external device in a vertical state or at a large tilt angle relative to the bearing surface. In the second usage state, both the first housing 10 and the second housing 20 are tilted relative to the bearing surface. The sides of the first housing 10 and the second housing 20 away from the hinge position respectively form a support cooperation with the bearing surface, so that the first housing 10 and the second housing 20 together form a triangular support structure, and keep the external device at a different tilt angle than in the first usage state, thereby allowing the user to select the appropriate support state according to the viewing angle or operation requirements.

[0034] The magnet 30 is disposed inside the second housing 20 and is used to connect the external device to the second housing 20. In use, the side of the second housing 20 with the magnet 30 faces the external device. The magnet 30 attracts the magnetic structure of the external device itself or the magnetic structure on the protective shell of the external device, so that the second housing 20 is detachably magnetically connected to the external device.

[0035] In this embodiment, the magnet 30 is in the form of a non-closed ring. The magnet 30 is arranged circumferentially to form a corresponding internal region. Most of the region of the magnet 30 is distributed circumferentially to provide magnetic attraction when the second housing 20 is connected to the external device, and to define the relative position between the second housing 20 and the external device.

[0036] The display component 40 is disposed inside the second housing 20. The display surface of the display component 40 and the magnetic attraction surface of the magnet 30 are located on opposite sides of the second housing 20. When the second housing 20 is magnetically connected to an external device through the magnet 30, the magnetic attraction surface of the magnet 30 faces the external device, and the display surface of the display component 40 faces the side away from the external device, thereby avoiding the external device from obstructing the display content of the display component 40.

[0037] The display component 40 includes an e-ink screen 41 and a display cover 42 covering the display side of the e-ink screen 41. The second housing 20 is provided with a display window 25 corresponding to the display area of ​​the e-ink screen 41. The image displayed on the e-ink screen 41 can be displayed to the outside of the second housing 20 through the display window 25 and the display cover 42.

[0038] The e-ink screen 41 can be used to display electronic photos, patterns, text or other image information, and can cooperate with the mounting slot 14 on the first housing 10 so that the e-ink screen 41 can be used to display electronic photos, and the mounting slot 14 can be used to place and display paper photos, so that the e-ink screen anti-loss magnetic bracket card holder can simultaneously have the functions of electronic image display and sheet display.

[0039] The projection of the display area of ​​the display component 40 in the thickness direction of the second housing 20 is at least partially located in the area enclosed by the magnet 30 along the circumferential direction, so that the magnet 30 and the display component 40 can form a corresponding spatial fit relationship within the limited space of the second housing 20, and the magnetic attraction side of the magnet 30 and the display side of the display component 40 are respectively facing the opposite sides of the second housing 20.

[0040] The second housing 20 is also provided with a coil 80 and a magnet 30 arranged around the circumference of the coil 80, so that the coil 80 is at least partially located in the area enclosed by the magnet 30 around the circumference, thereby forming an inner and outer spatial arrangement relationship between the magnet 30 and the coil 80 within the second housing 20.

[0041] The coil 80 has a power receiving end 81, and the second housing 20 is provided with a clearance hole 27 corresponding to the power receiving end 81. The power receiving end 81 passes through the clearance hole 27 and is electrically connected to the control component 50.

[0042] The magnet 30 adopts a non-closed ring structure, which can form a corresponding clearance space in the area of ​​the corresponding power connection end 81 and the clearance hole 27, so that the power connection end 81 can pass through the second housing 20 and connect to the control component 50, avoiding the power connection end 81 from going around significantly in the second housing 20 or interfering with the magnet 30, reducing the bending of the power connection end 81 and the stacking of different components in the thickness direction of the second housing 20.

[0043] The remaining portion of the magnet 30 is still distributed along the circumference of the coil 80, thereby retaining the corresponding magnetic attraction area while meeting the requirements for the insertion of the power connection terminal 81, so that the second housing 20 can maintain a stable magnetic connection with the external device.

[0044] The non-closed area of ​​magnet 30 can also form an area with relatively weak magnetic attraction. When the user needs to remove the e-ink screen anti-loss magnetic bracket from the external device, the second housing 20 can be lifted from the side corresponding to the non-closed area, so that the second housing 20 can be gradually separated from the external device from that side. This provides a peeling starting position for the magnetic connection between the second housing 20 and the external device and improves the ease of disassembling the e-ink screen anti-loss magnetic bracket.

[0045] The second housing 20 is provided with a receiving groove 28 for mounting a magnet 30 and a positioning groove 29 for mounting a coil 80. The magnet 30 is disposed in the receiving groove 28 and the coil 80 is disposed in the positioning groove 29. The positioning groove 29 is located in the area enclosed by the receiving groove 28 in the circumferential direction, and the clearance hole 27 is connected to the positioning groove 29.

[0046] The receiving groove 28 can accommodate and position the magnet 30, and the positioning groove 29 can position the coil 80, thereby restricting the movement of the magnet 30 and the coil 80 within the second housing 20 and maintaining the relative position between the magnet 30 and the coil 80.

[0047] Since the positioning groove 29 is located in the area enclosed by the receiving groove 28 in the circumferential direction, the magnet 30 and the coil 80 can be arranged in an inner and outer manner in the surface direction of the second housing 20, thereby reducing the size increase caused by the magnet 30 and the coil 80 occupying independent installation areas respectively, and helping the second housing 20 to maintain a relatively compact structure.

[0048] The clearance hole 27 is connected to the positioning groove 29, so that the power receiving end 81 of the coil 80 can pass through the clearance hole 27 from the position of the positioning groove 29 through the second housing 20 and be electrically connected to the control component 50, thereby reducing the winding distance of the power receiving end 81 in the second housing 20 and reducing the possibility of the power receiving end 81 being squeezed or bent and damaged.

[0049] The wireless communication component is disposed inside the second housing 20 and is electrically connected to the display component 40 and the control component 50 respectively. The wireless communication component is used to establish a wireless communication connection with external devices to realize image data transmission, location information acquisition, anti-loss reminders and corresponding information interaction.

[0050] In one embodiment, the wireless communication component includes a Bluetooth communication module and a positioning module. The Bluetooth communication module is used to establish a wireless communication connection with an external device and receive image data sent by the external device. The positioning module is used to provide location information of the e-ink screen anti-loss magnetic holder card holder.

[0051] In practical use, users can select the electronic photos or other images to be displayed on the external device. After the external device establishes a wireless communication connection with the Bluetooth communication module, it sends the corresponding image data to the Bluetooth communication module. After receiving the image data, the Bluetooth communication module transmits the image data to the control component 50, and the control component 50 controls the display component 40 to display the image corresponding to the image data.

[0052] The positioning module can provide the location information of the e-ink screen anti-loss magnetic holder card holder, enabling external devices to locate the e-ink screen anti-loss magnetic holder card holder based on the corresponding location information. The wireless communication connection between the Bluetooth communication module and the external device can also be used to reflect the connection status between the e-ink screen anti-loss magnetic holder card holder and the external device, so that the external device can issue corresponding anti-loss reminders when the wireless communication connection is disconnected or the preset connection conditions are not met.

[0053] In another embodiment, the wireless communication component includes a StarFlash communication module, which is used to establish a wireless communication connection with an external device and to transmit image data or other data as well as provide anti-loss reminders.

[0054] When using the StarFlash communication module, the external device can send image data to the wireless communication component to control the display component 40 via StarFlash communication. The wireless communication component provides the received image data to the control component 50, and the control component 50 controls the display component 40 to display the corresponding image. At the same time, it can provide anti-loss reminders based on the wireless communication status between the StarFlash communication module and the external device.

[0055] The combination of Bluetooth communication module and positioning module, as well as the star-flash communication module, constitute different implementations of wireless communication components. In practical applications, the appropriate wireless communication structure can be selected according to the communication method adopted by the product.

[0056] The control component 50 is disposed inside the second housing 20 and is electrically connected to the display component 40 and the wireless communication component respectively. The control component 50 is used to receive and process the image data transmitted by the wireless communication component, and control the e-ink screen 41 to refresh according to the image data, so that the e-ink screen 41 displays the corresponding electronic photo or other image.

[0057] Specifically, when the Bluetooth communication module or the Star Flash communication module receives image data sent by an external device, the control component 50 acquires the corresponding image data and controls the e-ink screen 41 to refresh according to the image data. After the e-ink screen 41 completes the refresh, the corresponding display content can be displayed to the outside through the display window 25 on the second housing 20 and the display cover 42.

[0058] The second housing 20 is also provided with a switch button 26, which is electrically connected to the control component 50 and is used to control the display component 40 to turn on or off. When the user operates the switch button 26, the switch button 26 provides a corresponding control signal to the control component 50, and the control component 50 controls the working state of the display component 40 according to the control signal.

[0059] In this embodiment, the e-ink screen anti-loss magnetic bracket wallet can magnetically connect the second housing 20 to external devices such as mobile phones via the magnet 30. Since the display surface of the display component 40 and the magnetic surface of the magnet 30 are located on opposite sides of the second housing 20, the display surface of the display component 40 can still face outward after the second housing 20 is magnetically connected to the external device.

[0060] When it is necessary to change the electronic photo displayed on the e-ink screen 41, the external device can send the corresponding image data to the wireless communication component through the Bluetooth communication module or the Star Flash communication module. The control component 50 controls the e-ink screen 41 to refresh according to the image data received by the wireless communication component, thereby changing the display content of the e-ink screen 41.

[0061] When the support function is needed, the first housing 10 is unfolded relative to the second housing 20 around the pivot 70. After the first housing 10 and the second housing 20 form an angle, the first housing 10 supports the second housing 20 and the external device magnetically connected to the second housing 20, so that the external device is placed on the desktop or other load-bearing surface at the corresponding tilt angle.

[0062] When the first housing 10 is unfolded, the user can place and display paper photos through the mounting slot 14 on the display side 13 of the first housing 10, and display electronic photos through the e-ink screen 41 on the second housing 20. This allows the first housing 10 to be used to hold cards and also to place sheet-like display pieces, and to serve as a support structure for the second housing 20 and external devices after unfolding.

[0063] When the stand function is not needed, the first housing 10 can rotate and retract relative to the second housing 20, bringing the first housing 10 and the second housing 20 closer together, thereby reducing the space occupied by the e-ink screen anti-loss magnetic stand card holder in the storage state.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
