Their initial development aimed to combine digital display with the traditional paper reading experience. An image is formed by the movement of charged particles within microcapsules driven by an electric field, and the image is developed using ambient light reflection, retaining the displayed content without the need for continuous power supply. Over time, from early monochrome displays to the introduction of multicolor and flexible products, its applications have expanded from e-book readers to electronic price tags, smart wearable devices, public information signs, and many other fields, becoming an important device for digital information display that balances practicality and user experience.

[0003] Existing e-ink displays typically consist of an electronic display device and an outer frame. The outer frame is used to fix and protect the electronic display device, ensuring its structural stability during use and adapting to external installation scenarios. The electronic display device, as the core display component, works with the outer frame to form a complete display terminal, thereby meeting information display needs. However, since the electronic display device and the outer frame are often integrated, the same electronic display device cannot be adapted to outer frames of different sizes or types. This not only limits the flexibility of use of the electronic display device but also increases maintenance costs.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing e-ink screens often use a one-piece structure for the electronic display device and the outer frame, which makes it impossible for the same electronic display device to be adapted to frames of different sizes or types. This not only limits the flexibility of use of the electronic display device but also increases maintenance costs. The technical solution adopted by this utility model to solve this problem is as follows: An electronic ink screen display device includes a frame housing and a display component. The display component includes an electronic ink screen and a mounting bracket for mounting the electronic ink screen. The frame housing has a display area corresponding to the electronic ink screen, and the mounting bracket is detachably connected to the frame housing.

[0008] Furthermore, the mounting bracket includes a second support plate located below and connected to the first support plate, and an installation space is formed between the first support plate and the second support plate. The display component includes a main control module electrically connected to the e-ink screen, and the main control module is disposed within the installation space.

[0009] Furthermore, the mounting groove is provided with a stress buffer for relieving the edge stress of the electronic ink screen.

[0010] Furthermore, multiple stress buffers are provided, and the multiple stress buffers are spaced apart along the circumferential direction of the mounting groove.

[0011] Furthermore, the mounting bracket also includes a connector for connecting the first support plate and the second support plate, the connector being arranged vertically, and the mounting space between the first support plate and the second support plate being an open structure with open sides.

[0012] Furthermore, both the first support plate and the second support plate are made of rigid plastic material.

[0013] Furthermore, both the first support plate and the mounting groove have rectangular cross-sections. The first support plate includes a first side and a second side connected to the first side. The mounting groove includes a third side and a fourth side connected to the third side. The length of the first side is L1, 180mm≤L1≤200mm. The length of the second side is L2, 120mm≤L2≤140mm. The length of the third side is L3, 150mm≤L3≤170mm. The length of the fourth side is L4, 100mm≤L4≤110mm.

[0014] Furthermore, the first support plate is provided with a wire-passing hole, which is connected to the installation space.

[0015] The beneficial effects of this utility model are as follows: This invention provides a mounting bracket for installing an e-ink screen. The mounting bracket is detachably connected to the picture frame housing. Simultaneously, a display area is provided on the picture frame housing corresponding to the position of the e-ink screen. This allows the same display component to be adapted to picture frame housings of different sizes or types, breaking the limitations of traditional integrated structures. This improves the flexibility and compatibility of the display component, helps reduce maintenance costs, and effectively solves the problem that existing e-ink screens often use an integrated structure for the electronic display device and the outer frame, making it impossible for the same electronic display device to be adapted to outer frames of different sizes or types. This not only limits the flexibility of the electronic display device but also increases maintenance costs.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0017] Figure 1 This is one of the exploded views of the electronic ink screen display device of this utility model; Figure 2 This is the second exploded view of the electronic ink screen display device of this utility model; Figure 3 This is one of the structural schematic diagrams and a partially enlarged schematic diagram of the first support plate of this utility model; Figure 4 This is the second structural schematic diagram of the first support plate of this utility model. Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 4 An electronic ink screen display device is shown, including a frame housing 1 and a display component. The display component includes an electronic ink screen 21 and a mounting bracket for mounting the electronic ink screen 21. The frame housing 1 is provided with a display area 10 corresponding to the electronic ink screen 21. The mounting bracket is detachably connected to the frame housing 1. This invention provides a mounting bracket for installing an e-ink screen. The mounting bracket is detachably connected to the picture frame housing. Simultaneously, a display area is provided on the picture frame housing corresponding to the position of the e-ink screen. This allows the same display component to be adapted to picture frame housings of different sizes or types, breaking the limitations of traditional integrated structures. This improves the flexibility and compatibility of the display component, helps reduce maintenance costs, and effectively solves the problem that existing e-ink screens often use an integrated structure for the electronic display device and the outer frame, making it impossible for the same electronic display device to be adapted to outer frames of different sizes or types. This not only limits the flexibility of the electronic display device but also increases maintenance costs.

[0020] Furthermore, when it is necessary to replace the frame housing 1 or repair the e-ink screen 21, the display component can be removed simply by disassembling the connecting structure, without the need to replace the entire device, which helps to reduce maintenance difficulty and cost.

[0021] Specifically, the cross-sectional dimension of the frame housing 1 is greater than or equal to the cross-sectional dimension of the display component, providing a structural basis for the detachable adaptation of the display component and the frame housing 1. When the display component is installed on the frame housing 1, the frame housing 1 can completely cover the edge of the display component, which not only ensures the structural fit and stability after the two are connected, but also provides comprehensive protection for the display component through its own size adaptation, avoiding edge bumps and damage. At the same time, the cross-sectional dimension of the frame housing 1 is greater than or equal to the cross-sectional dimension of the display component, which is conducive to the compatibility of the same display component with different frame housings 1.

[0022] Optionally, in some embodiments, the frame housing 1 is configured with a through-hole structure corresponding to the display area 10 of the e-ink screen 21, and the size of the cutout is the same as the size of the display surface of the e-ink screen 21, so that the display surface of the e-ink screen 21 is directly exposed after installation.

[0023] Optionally, in some embodiments, a transparent acrylic or glass panel is embedded in the corresponding position of the frame housing 1, and the edge of the panel is fixedly connected to the frame housing 1 to form a closed display area 10, with the electronic ink screen 21 installed inside the panel.

[0024] Optionally, in some embodiments, the inner side of the picture frame housing 1 is provided with an elastic buckle corresponding to the position of the mounting bracket, and the edge of the mounting bracket is provided with a matching slot. During assembly, the mounting bracket is pushed into the picture frame housing 1, and the elastic buckle is engaged with the slot to achieve fixation. During disassembly, the buckle can be pressed to separate it without the need for additional tools.

[0025] Optionally, in some embodiments, the mating surfaces of the mounting bracket and the picture frame housing 1 are respectively embedded with attractive permanent magnets and magnetic conductive sheets, and positioning bosses and positioning grooves are set at corresponding positions. During assembly, they are attached by magnetic attraction, and the positioning bosses and positioning grooves assist in precise alignment. During disassembly, they can be separated by gently pulling.

[0026] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the mounting bracket is provided with a through screw hole on its edge, and the picture frame housing 1 is provided with an internal thread post at the corresponding position. The two are fixed by screwing a cross screw through the screw hole and engaging with the internal thread post.

[0027] like Figures 1 to 4 The picture frame housing 1 shown includes a picture frame cover 11 and a picture frame base plate 12 detachably connected to the picture frame cover 11. The picture frame cover 11 and the picture frame base plate 12 enclose a receiving cavity for accommodating the display component. Furthermore, the detachable connection between the mounting bracket and the frame housing 1 helps to break the size constraints of the traditional integrated structure. The same display component can be flexibly matched with different sizes or types of frame housing 1, without the need to set up a separate display component for a specific scenario.

[0028] Furthermore, when users need to install, replace, or repair the display components, they only need to remove the bottom plate 12 of the frame to directly access the display components from the rear, without damaging the overall structure of the frame or forcibly removing the frame cover 11, which helps to improve the ease of operation.

[0029] Optionally, in some embodiments, the display component is pre-fixed to the frame base plate 12. The fixing method can be screw fastening or snap-fit, to ensure the installation stability and positional accuracy of the display component on the frame base plate 12. The frame cover 11 is designed as a front cover structure, and its front side has a display area 10 corresponding to the area of ​​the e-ink screen 21, ensuring that the display content is presented without obstruction. The frame cover 11 and the frame base plate 12 can be connected by snap-fit ​​connection, threaded connection, slot connection or magnetic connection, and the two enclose a sealed receiving cavity to stably encapsulate the pre-fixed display component in the receiving cavity.

[0030] Optionally, in some embodiments, the display component is fixed by a clamping mechanism, without the need for additional pre-fixing steps; the inner side of the frame cover 11 is provided with a positioning step or pressing edge, and the frame base plate 12 is provided with a matching support surface or locking position at the corresponding position. During assembly, the display component is placed between the two. After the frame cover 11 and the frame base plate 12 are locked, the positioning step, pressing edge, support surface, and locking position work together to clamp and fix the display component from the edge; furthermore, in order to avoid the e-ink screen 21 from breaking due to uneven clamping pressure or excessive force, an elastic buffer pad can be added to the contact area between the frame cover 11 and the frame base plate 12.

[0031] Optionally, in some embodiments, the frame cover 11, the frame base plate 12, and the display component are coordinated and fixed through a common connecting member; specifically, the frame cover 11 and the frame base plate 12 are connected by screws or pull buckles that penetrate the receiving cavity, and the mounting bracket of the display component is provided with a corresponding through hole or slot; during assembly, the connecting member passes through the through hole or slot of the frame cover 11 and the mounting bracket in sequence, and finally locks with the frame base plate 12, so that the display component is pressed by screws or limited by buckles in the receiving cavity, and the fixing of the three components is completed simultaneously.

[0032] like Figures 1 to 4 The mounting bracket shown includes a first support plate 221, and the first support plate 221 has a mounting groove 220 on the side near the picture frame cover 11, and the electronic ink screen 21 is embedded in the mounting groove 220; Furthermore, the mounting groove 220 on the first support plate 221 provides an embedded space for the e-ink screen 21 that is adapted to the screen size. The edge of the e-ink screen 21 can fit tightly with the groove wall of the mounting groove 220. During assembly, no additional calibration is required to quickly complete the alignment. This preset positioning structure helps to avoid problems such as screen offset and tilt during assembly, which helps to greatly simplify the installation operation and effectively improve the overall assembly efficiency and assembly accuracy.

[0033] Furthermore, the mounting groove 220 forms a wrapping limit on the circumferential edge of the e-ink screen 21, making the e-ink screen 21 and the mounting bracket form a stable whole. During the transportation, use or disassembly of the equipment, this structure can effectively limit the displacement and shaking of the screen, avoid poor circuit contact or structural damage caused by the loosening of the e-ink screen 21, and help ensure the stability of the overall structure of the equipment.

[0034] like Figures 1 to 4 The mounting bracket shown includes a second support plate 222 located below and connected to the first support plate 221, with an installation space formed between the first support plate 221 and the second support plate 222. The display component includes a main control module electrically connected to the e-ink screen 21, and the main control module is located within the installation space. Furthermore, the main control module is rationally arranged in the installation space between the first support plate 221 and the second support plate 222, which helps to avoid occupying additional external or lateral space of the display components and helps to achieve the thinness and compactness of the device.

[0035] Furthermore, the main control module is positioned close to the e-ink screen 21, which helps to significantly reduce the length of the connecting cable between the two, thus reducing the risk of signal attenuation and interference, effectively improving the stability and response speed of the display driver, while reducing cable costs and wiring complexity.

[0036] Optionally, the main control module can be installed in the installation space between the first support plate 221 and the second support plate 222 through connection methods such as snap-fit ​​connection, slot connection, and threaded connection.

[0037] Specifically, the main control module is the core control unit in the display component, used to drive and manage the display content of the e-ink screen. It includes the main control chip, display driver circuit, storage unit and power management circuit, etc. It is electrically connected to the e-ink screen 21 through a flexible ribbon cable or connector. It is responsible for receiving external instructions or pre-stored data and converting them into drive signals that the screen can recognize in order to refresh and maintain images or text.

[0038] like Figures 1 to 4 The mounting groove 220 shown is provided with a stress buffer 223 for relieving the edge stress of the electronic ink screen 21; Furthermore, the e-ink screen 21 is typically made of glass substrate or brittle encapsulation material, and its edges and corners are prone to stress concentration when subjected to impact, vibration or thermal expansion and contraction; the stress buffer part 223 reduces the rigid constraint of the mounting groove 220 on the screen edge by partially avoiding stress, thereby preventing stress from being directly transmitted to the e-ink screen 21 body and effectively preventing cracking or breakage.

[0039] Furthermore, during transportation, installation, or daily use, the device may be subjected to drops or vibrations; the stress buffer 223, as a structural buffer, can absorb or disperse local deformation energy, which is beneficial to enhancing the overall impact resistance and helping to extend the service life of the e-ink screen 21.

[0040] Optionally, in some embodiments, the stress buffer 223 is provided with corner holes. Holes are made at the four corners of the mounting groove 220 corresponding to the four corners of the e-ink screen 21. The holes can be circular, elliptical, rectangular or diamond-shaped through holes. When the e-ink screen 21 is subjected to impact, vibration or thermal expansion and contraction and generates stress, the hole area can provide local deformation space to release stress energy and avoid stress directly concentrating at the corners of the screen, thereby effectively preventing the e-ink screen 21 from cracking or breaking due to stress concentration.

[0041] Optionally, in some embodiments, the stress buffer 223 is provided with an edge notch, and a U-shaped, V-shaped or arc-shaped notch is cut out on the side or corner edge of the mounting groove 220 so that the edge of the e-ink screen 21 does not directly contact the first support plate 221 in the notch area, thereby reducing the rigid constraint of the mounting groove 220 on the edge of the screen; when the screen is subjected to impact, vibration or thermal expansion and contraction, the notch area provides a clearance space to avoid stress concentration at the edge or corner, thereby effectively preventing the e-ink screen 21 from cracking or breaking.

[0042] Optionally, in some embodiments, the stress buffer 223 is a ring of silicone or foam strips circumferentially disposed on the inner wall of the mounting groove 220. When the e-ink screen 21 is embedded, the edge contacts the elastic material. When the screen is subjected to impact, vibration or thermal expansion and contraction, the elastic material absorbs energy through its own deformation, avoids stress transmission caused by rigid collision, and fills the gaps to achieve buffer protection.

[0043] like Figures 1 to 4 The stress buffer section 223 shown is provided in multiple ways, and the multiple stress buffer sections 223 are spaced apart along the circumferential direction of the mounting groove 220; Furthermore, when the e-ink screen 21 is subjected to drops, pressure, or temperature changes, stress is often generated at multiple points along the edge, rather than being concentrated in a single location. Multiple stress buffers 223 are distributed circumferentially, which can form multiple stress release points at the edge of the screen, avoiding local stress accumulation and thus providing more comprehensive protection for the screen.

[0044] Furthermore, in actual use, the device may be impacted from any direction; the circumferentially spaced buffer structure ensures that at least one or more stress buffers 223 can effectively function regardless of the direction of the impact, which helps to improve the isotropic shock resistance.

[0045] Furthermore, the spacing arrangement can retain sufficient support area while facilitating local flexible avoidance, thereby balancing structural strength and buffering requirements.

[0046] like Figures 1 to 4 The mounting bracket shown also includes a connector for connecting the first support plate 221 and the second support plate 222. The connector is arranged in a vertical direction, and the mounting space between the first support plate 221 and the second support plate 222 is an open structure with open sides. Alternatively, the open structure on all sides allows the main control module to be installed or removed without disassembling the entire mounting bracket, enabling users to operate directly from the side, which improves assembly efficiency and ease of maintenance later.

[0047] Furthermore, the open installation space allows air to circulate around the main control module, effectively removing the heat generated by the electronic components during operation and preventing excessive temperature rise due to a closed environment, thereby improving the stability and service life of the device.

[0048] Furthermore, compared to a closed box structure, the frame-type support formed by vertical connectors significantly reduces the amount of material used, achieving lightweighting while ensuring structural rigidity, which helps reduce manufacturing costs and product transportation burden.

[0049] Optionally, in some embodiments, the connector is a vertical connecting column. One or more cylindrical or square vertical connecting columns are provided at corresponding corners or edges of the first support plate 221 and the second support plate 222. The connecting column can be integrally formed with any support plate by injection molding or other means, and the other end is fixed to the other support plate by screws, clips or adhesives. The simple columnar connection achieves stable support for the two support plates. At the same time, since the connecting column is only set at specific positions, the circumferential openness of the installation space can be maximized, which is convenient for heat dissipation of internal components, wiring and subsequent maintenance operations.

[0050] Optionally, in some embodiments, the connector adopts a combination structure of screws and through holes; specifically, the first support plate 221 and the second support plate 222 are respectively provided with through holes at their corresponding positions; during assembly, fasteners such as screws, bolts or studs are passed through in the vertical direction and through the through holes on the two support plates, thereby fastening the two together as a whole. In this structure, the connector is the fastener itself, such as the screw; furthermore, it can also be used with auxiliary components such as sleeves or pillars as needed to enhance the length or stability of the connection.

[0051] Optionally, in some embodiments, the connectors are side ribs or reinforcing ribs integrally formed with the first support plate 221 and the second support plate 222, respectively; the mounting bracket adopts an integral structure, integrally formed by injection molding or stamping process, and the first support plate 221 and the second support plate 222 are directly connected by a number of side ribs or reinforcing ribs extending in the vertical direction to form a stable frame structure. These side ribs or reinforcing ribs are arranged on the edge or inside non-critical shielding areas of the mounting bracket, which ensures structural strength and support stability while maximizing the circumferential openness of the installation space, which is conducive to heat dissipation, wiring and subsequent maintenance of internal components.

[0052] like Figures 1 to 4 The first support plate 221 and the second support plate 222 shown are both made of rigid plastic material; Furthermore, rigid plastic has a high elastic modulus and resistance to deformation, which can provide stable support for the e-ink screen 21 and the main control module without increasing the thickness, avoiding screen pressure or loosening of connections due to bending of the mounting bracket, and helping to ensure assembly accuracy during long-term use.

[0053] Furthermore, compared to metal materials, rigid plastics have a low density, which helps to significantly reduce the weight of the entire display device, making it easier to wall-mount, move, or hang as a decorative painting for a long time, and helps to reduce the load-bearing requirements of the installation structure.

[0054] Optionally, in some embodiments, the rigid plastic material is ABS (acrylonitrile-butadiene-styrene copolymer) plastic, which has good rigidity, impact strength and weather resistance, is easy to injection mold, and has a high surface smoothness.

[0055] Optionally, in some embodiments, the rigid plastic material is PC (polycarbonate) plastic, which has the characteristics of high strength, high impact resistance, dimensional stability, and can be transparent or opaque.

[0056] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, both the first support plate 221 and the second support plate 222 are acrylic sheets, which have the characteristics of high transparency, high surface hardness, easy processing, and good weather resistance.

[0057] like Figures 1 to 4 The cross-sections of the first support plate 221 and the mounting groove 220 shown are both rectangular. The first support plate 221 includes a first side 2211 and a second side 2212 connected to the first side 2211. The mounting groove 220 includes a third side 2201 and a fourth side 2202 connected to the third side 2201. The length of the first side 2211 is L1, 180mm≤L1≤200mm. The length of the second side 2212 is L2, 120mm≤L2≤140mm. The length of the third side 2201 is L3, 150mm≤L3≤170mm. The length of the fourth side 2202 is L4, 100mm≤L4≤110mm. Optionally, in some embodiments, L1=180mm, L2=120mm, L3=150mm, and L4=100mm. This size combination is suitable for small-sized e-ink screen 21 devices, such as portable e-readers and small industrial control panels. The first support plate 221 can provide a compact installation space, while the mounting slot 220 can be adapted to mainstream e-ink screens 21. The compact structural design not only saves space but also reduces the overall weight of the device, making it easy to carry or embed in small devices. At the same time, the size difference between the mounting slot and the first support plate 221 can be used to set a stress buffer 223, which is beneficial to balance structural stability and practicality.

[0058] Optionally, in some embodiments, L1=200mm, L2=140mm, L3=170mm, and L4=110mm. This size combination is for medium to large-sized e-ink screen 21 applications, such as 10-12 inch electronic drawing tablets, smart office monitors, etc. The first support plate 221 and the mounting groove 220 can accommodate larger e-ink screens 21. The larger area of ​​the first support plate 221 and the mounting groove 220 is beneficial to improving structural stability and helps to reduce stress concentration at the screen edge.

[0059] Furthermore, as a preferred embodiment of this utility model and not a limitation, L1=198mm, L2=133mm, L3=167mm, and L4=109mm. This size is an optimized setting for a specific customized e-ink screen 21, which minimizes the bezel width while ensuring reliable screen embedding, thus improving the screen-to-body ratio.

[0060] like Figures 1 to 4 The first support plate 221 shown is provided with a wire hole 2213, which is connected to the installation space; Furthermore, the wire hole 2213 provides a channel for the wiring between the e-ink screen 21 and the main control module, which helps to avoid the wiring from being tangled or exposed, reducing the risk of wiring damage or poor contact caused by friction or pulling; at the same time, the neat wiring layout facilitates later inspection and maintenance, and improves the overall connection stability and reliability of the equipment.

[0061] Furthermore, by rationally arranging the position of the wire hole 2213, such as near the interface area of ​​the e-ink screen 21, it is beneficial to shorten the wiring path and reduce the bending radius of the cable, which helps to alleviate the risk of joint fatigue or breakage caused by frequent disassembly or thermal expansion and contraction, and effectively extends the service life.

[0062] Furthermore, during the assembly process, the operator can first fix the e-ink screen 21 to the mounting slot 220, and then pass the ribbon cable through the cable hole 2213 to connect to the main control module, making the process clear; during maintenance, the connector can also be directly plugged and unplugged from the mounting space side without disassembling the screen, which helps to improve serviceability.

[0063] The implementation method of Example 1 is as follows: An electronic ink screen display device includes a frame housing 1 and a display component. The display component includes an electronic ink screen 21 and a mounting bracket for mounting the electronic ink screen 21. The frame housing 1 has a display area 10 corresponding to the electronic ink screen 21. The mounting bracket is detachably connected to the frame housing 1.

[0064] This invention provides a mounting bracket for installing an e-ink screen. The mounting bracket is detachably connected to the picture frame housing. Simultaneously, a display area is provided on the picture frame housing corresponding to the position of the e-ink screen. This allows the same display component to be adapted to picture frame housings of different sizes or types, breaking the limitations of traditional integrated structures. This improves the flexibility and compatibility of the display component, helps reduce maintenance costs, and effectively solves the problem that existing e-ink screens often use an integrated structure for the electronic display device and the outer frame, making it impossible for the same electronic display device to be adapted to outer frames of different sizes or types.
