Description

Technical Field

[0001] This invention belongs to the field of display device decoration technology, and in particular relates to a picture frame and a picture frame display device. Background Technology

[0002] The market has begun to move towards framed televisions, with some manufacturers already producing some models. In existing technology, joining two frame strips requires using L-shaped corner brackets: the brackets are inserted into the end of one frame strip, and then the end of the other frame strip is aligned with the brackets and inserted. Furthermore, when assembling the last frame strip, screws are needed to fix a straight corner bracket to its end. The entire process is cumbersome and results in low assembly efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a picture frame and a picture frame display device, which aims to improve assembly efficiency.

[0004] The technical solution of this invention is implemented as follows: This invention provides a picture frame, which includes a frame structure and a splicing assembly. The frame structure includes multiple splicing frame strips that surround and frame the periphery of a display device. The splicing assembly includes two snap-fit ​​components respectively disposed at the splicing ends of two adjacent splicing frame strips. Each snap-fit ​​component is integrally formed and includes a main body and a snap-fit ​​portion. The main body is connected to the corresponding splicing frame strip, and the snap-fit ​​portions of the two snap-fit ​​components snap together to splice the two adjacent splicing frame strips together.

[0005] In one embodiment, one of the two snap-fit ​​components has a snap-fit ​​portion including a snap protrusion, and the other has a snap-fit ​​portion including a snap groove with an opening on one side; the opening of the snap groove is used to guide the snap protrusion, and the width of the opening of the snap groove is less than the maximum width of the snap protrusion.

[0006] In one embodiment, the outer surface of the card protrusion and the inner wall of the card slot are both arc surfaces, and extend along the thickness direction of the splicing frame strip.

[0007] In one embodiment, the back side of the main body of the snap-fit ​​component is attached to the inner side of the splicing frame strip; wherein the snap-fit ​​portion is formed on the front side of the main body.

[0008] In one embodiment, the root of the latching protrusion is connected to the corresponding body portion via a connecting arm to form a gap between the body portion and the latching protrusion, the gap allowing the opening side of the latching slot to extend into; and / or, The bottom of the card slot is connected to the corresponding main body portion; and / or, The main body has a mating surface, and when the two adjacent splicing frame strips are spliced ​​together, the mating surfaces of the main bodies of the two snap-fit ​​parts fit together and abut against each other.

[0009] In one embodiment, the main body is attached to the inner wall of the splicing frame; the snap-fit ​​component further includes a support portion that extends toward the inner side away from the splicing frame to abut against the display device.

[0010] In one embodiment, the snap-fit ​​portion and the support portion of each of the snap-fit ​​components are respectively located at both ends of the main body in the extension direction of the corresponding splicing frame strip.

[0011] In one embodiment, the main body has a break groove formed at one end near the support portion, and the break groove penetrates the main body along the thickness direction of the frame structure.

[0012] In one embodiment, a magnetic suction element is also included, which is disposed on the inner side of the splicing frame strip to attract the display device.

[0013] The present invention also provides a picture frame display device, the picture frame display device including a display device and a picture frame, the picture frame being disposed around the periphery of the display device; the picture frame including a frame structure and a splicing assembly, the frame structure including a plurality of splicing frame strips, the plurality of splicing frame strips surrounding and framing the periphery of the display device; the splicing assembly including two snap-fit ​​components respectively disposed at the splicing ends of two adjacent splicing frame strips; each snap-fit ​​component is integrally formed and includes a main body and a snap-fit ​​part, the main body being connected to the corresponding splicing frame strip, and the snap-fit ​​parts of the two snap-fit ​​components snapping into each other to splice the two adjacent splicing frame strips together.

[0014] The picture frame provided by this invention replaces the traditional L-shaped corner bracket insertion and screw fastening process with a quick-connect mechanism of snap-fit ​​components. This achieves instant positioning and fixation between the frame strips, simplifies the assembly process, and improves the assembly efficiency of the picture frame. More importantly, it greatly reduces the risk of damage to the splicing components. Because the two snap-fit ​​components in this embodiment adopt a separable design, rather than a traditional one-piece splicing structure, when the external force on the splicing component exceeds the snap-fit ​​strength of the snap-fit ​​part, the two snap-fit ​​components can separate along the snap-fit ​​point. This "separation and stress relief" method avoids irreversible structural damage to the splicing component due to stress concentration. Attached Figure Description

[0021] The market has begun to move towards framed televisions, with some manufacturers already producing some models. In existing technology, joining two frame strips requires first using L-shaped corner brackets. These brackets are inserted into the end of one frame strip, and then the end of the other frame strip is aligned with the brackets and inserted. Furthermore, when assembling the last frame strip, screws are needed to fix a straight corner bracket to its end. The entire process is cumbersome, resulting in low assembly efficiency.

[0022] In view of this, embodiments of the present invention provide a picture frame for a display device, which aims to improve splicing efficiency.

[0023] Please see Figure 1 and Figure 2 The frame 100 includes a frame structure 1 and splicing components 2. The frame structure 1 includes multiple splicing frame strips 11, which enclose the periphery of the display device. The splicing frame strips 11 have various structural forms, such as a cross-sectional shape similar to channel steel, including a bottom wall and side walls extending from opposite sides of the bottom wall to form a U-shaped cross-section with the opening facing the display device, or other cross-sectional configurations that can adapt to the edge contour of the display device.

[0024] Please combine Figure 3 and Figure 4 The splicing component 2 includes two snap-fit ​​parts 21 respectively disposed at the splicing ends of two adjacent splicing frame strips 11. Each snap-fit ​​part 21 is integrally formed, with a simple structure and easy mass production. Each snap-fit ​​part 21 includes a main body 211 and a snap-fit ​​part 212. The main body 211 serves as the connecting base and is fixed to the corresponding splicing frame strip 11, while the snap-fit ​​part 212 is used to realize the mechanical connection between adjacent frame strips. The snap-fit ​​parts 212 of the two snap-fit ​​parts 21 interlock with each other, enabling adjacent splicing frame strips 11 to be quickly spliced ​​and positioned without the need for additional fasteners, significantly simplifying the assembly process.

[0025] In actual assembly, the operator only needs to bring the ends of adjacent splicing frame strips 11 closer together, align the snap-fit ​​parts 212 of the two snap-fit ​​parts 21, and apply appropriate pressing force to complete the snap-fit ​​fixation. This snap-fit ​​connection method is reliable and easy to operate. Compared with the traditional one-piece molded L-shaped corner bracket insertion method, the splicing component 2 provided in this embodiment of the invention eliminates the screw fastening process through the butt joint design of the split snap-fit ​​parts 21, achieving an instant fixation effect of snap-fit ​​and splicing, and significantly shortening the assembly time of a single frame.

[0026] There are several ways in which the snap-fit ​​parts 212 of the two snap-fit ​​parts 21 can snap together. For example, one snap-fit ​​part 212 is provided with an elastic latch, and the other snap-fit ​​part 212 is provided with a corresponding latch hole. The elastic latch deforms elastically under external force and then snaps into the latch hole, thereby fixing the two snap-fit ​​parts 21 together. Alternatively, the snap-fit ​​parts 212 of the two snap-fit ​​parts 21 can be provided with interlocking toothed structures, which limit and fix the splicing direction through toothed meshing. Or, one snap-fit ​​part 212 is provided with a rotating hook, and the other snap-fit ​​part 212 is provided with a corresponding hanging post, which is connected by rotating snap-fit.

[0027] Furthermore, the snap-fit ​​component 21 can be made of plastic or metal and integrally manufactured through injection molding or stamping. The connection method between the main body 211 and the splicing frame 11 can be flexibly selected according to the material characteristics. For splicing frame 11 made of plastic or metal, the main body 211 can be glued and fixed to the inner wall or outer surface of the end of the frame strip using adhesive. The adhesive used is a high-temperature resistant and aging-resistant structural adhesive to ensure long-term reliability. For plastic or composite material frame strips, the main body 211 can also be made using an embedded injection molding process to form an integrated structure with the frame strip, further improving the connection strength.

[0028] The picture frame 100 provided in this embodiment of the invention includes a frame structure 1 and a splicing assembly 2. The frame structure 1 includes multiple splicing frame strips 11, which enclose the periphery of the display device. The splicing assembly 2 includes two snap-fit ​​parts 21 respectively disposed at the splicing ends of two adjacent splicing frame strips 11. Each snap-fit ​​part 21 is integrally formed and includes a main body 211 and a snap-fit ​​part 212. The main body 211 is connected to the corresponding splicing frame strip 11, and the snap-fit ​​parts 212 of the two snap-fit ​​parts 21 snap-fit ​​each other to splice adjacent splicing frame strips 11 together. This embodiment of the invention replaces the traditional L-shaped corner bracket insertion and screw fastening process with a quick-connection mechanism of the snap-fit ​​parts 21, realizing instant positioning and fixing between splicing frame strips 11, simplifying the assembly process, and improving the assembly efficiency of the picture frame 100.

[0029] More importantly, it greatly reduces the risk of damage to the splicing component 2. Because the two snap-fit ​​parts 21 in this embodiment of the invention adopt a separable design, rather than a traditional one-piece splicing structure, when the external force on the splicing component 2 exceeds the snap-fit ​​strength of the snap-fit ​​part 212, the two snap-fit ​​parts 21 can separate along the snap-fit ​​point. In this way, irreversible structural damage to the splicing component 2 due to stress concentration is avoided through the "separation and stress relief" method. The specific reasons can be analyzed in detail from the following aspects: First, the detachable design allows for external force buffering, preventing rigid damage. Traditional L-shaped corner brackets with plug-in and screw fastening structures form a rigid connection. When the splicing frame 11 is subjected to external forces such as collisions or compression, the external force is directly transmitted to the connection between the corner bracket and the frame, and the force cannot be relieved through structural separation. This can easily lead to deformation of the corner bracket, stripping of screws, or cracking at the end of the frame due to stress concentration, resulting in permanent damage to the splicing assembly. In this invention, the two snap-fit ​​parts 21 are separable snap-fit. When an external force is applied to the splicing frame strip 11, if the external force is less than the snap-fit ​​strength of the snap-fit ​​part 212, the snap-fit ​​structure can remain stable and ensure a firm splice. If the external force exceeds the snap-fit ​​strength, the snap-fit ​​parts 212 of the two snap-fit ​​parts 21 will automatically separate. The external force will be buffered and released with the separation action and will not be continuously transmitted to the main body 211 of the snap-fit ​​part 21 and the connection part with the splicing frame strip 11, thereby avoiding the breakage of the main body 211, the cracking of the snap-fit ​​part 212, or the failure of the connection between the main body 211 and the splicing frame strip 11 (such as adhesive detachment).

[0030] Secondly, the detachable design reduces the risk of damage during disassembly and maintenance. Traditional splicing structures (such as screw-locked structures) require tools to tighten the screws during assembly and disassembly. Improper operation can easily lead to stripped screws and worn corner brackets, and repeated disassembly and assembly continuously weakens the structural strength of the splicing components. In contrast, the detachable design of the snap-fit ​​parts 21 in this invention allows for easy assembly by simply aligning and applying a pushing force to the snap-fit ​​parts 212, and easy disassembly by applying a reverse pulling force. No additional tools are needed, making the operation convenient and preventing mechanical damage to the snap-fit ​​parts 212 and the main body 211. Even if excessive force is applied during disassembly and assembly, only the snap-fit ​​parts 212 will separate, without damaging the snap-fit ​​parts themselves. After separation, they can be re-aligned and reused, significantly reducing the probability of damage to the splicing components during disassembly, assembly, and maintenance.

[0031] Third, the detachable design adapts to different stress scenarios, avoiding damage from localized overload. During transportation, installation, or daily use, the frame 100 may be subjected to external forces of different directions and magnitudes (such as collisions during handling, bumps during daily use, and localized pressure from the weight of the display device itself). If the snap-fit ​​component 21 is an integral structure, when a localized overload occurs, the overload stress will concentrate at the snap-fit ​​point, easily leading to cracking of the snap-fit ​​part and deformation of the main body. However, the detachable design can automatically adapt to the magnitude of the external force. When the localized force exceeds the snap-fit ​​strength, the snap-fit ​​part 212 separates, dispersing and releasing the overload stress, avoiding structural damage caused by localized stress concentration. Moreover, after separation, it only needs to be reassembled to restore its use, without replacing the entire splicing component 2, which reduces both the risk of damage and maintenance costs.

[0032] Fourth, the detachable design and the integrated structure of the snap-fit ​​components work together to further enhance damage resistance. Each snap-fit ​​component 21 is integrally molded, and the connection strength between the main body 211 and the snap-fit ​​part 212 is sufficient to withstand normal external forces during normal use. The detachable snap-fit ​​between the two snap-fit ​​components is equivalent to setting a "flexible buffer node" at the splicing part. This ensures the splicing firmness during normal use and protects the snap-fit ​​components themselves from damage by separating them when encountering abnormal external forces. This achieves the dual effect of "firmness during normal use and stress relief under abnormal conditions," significantly reducing the risk of damage to the splicing component 2 compared to the traditional rigid splicing structure.

[0033] In some embodiments, please refer to Figure 4 and Figure 5 To address the challenges of existing snap-fit ​​connections (such as elastic latches and toothed engagement types), including difficulties in assembly alignment, susceptibility to fatigue deformation due to repeated disassembly and reassembly, and cumbersome operation steps in rotary snap-fit ​​systems, a mating structure consisting of a snap protrusion 212a and a single-sided open slot 212b is adopted. Specifically, one of the two snap-fit ​​mating parts 21 includes a snap protrusion 212a in its engagement portion 212, while the other includes a slot 212b with an opening on one side. The opening of the slot 212b is used to guide the snap protrusion 212a. Furthermore, the width of the opening of the slot 212b is less than the maximum width of the snap protrusion 212a. Thus, after the snap protrusion 212a is engaged in the slot 212b, the edge of the opening of the slot 212b acts as a limiting barrier, preventing the snap protrusion 212a from disengaging from the opening side.

[0034] During assembly, the operator aligns the splicing ends of two adjacent splicing frame strips 11, aligning the locking protrusion 212a with the opening of the locking groove 212b, and applies a linear thrust along the splicing direction of the two splicing frame strips 11. As the locking protrusion 212a slides in, the opening can expand slightly to accommodate its passage. After the locking protrusion 212a is in place, the opening elastically rebounds, forming a circumferential constraint on the locking protrusion 212a, completing the initial locking and positioning. At this time, due to the constraint of the two side walls of the splicing frame strip 11, in the direction perpendicular to the plane of the frame 100 (represented by the dashed line N1 in the figure), when the locking protrusion 212a is fully engaged in the locking groove 212b, the two side walls of the splicing frame strip 11 will clamp and limit the locking protrusion 212a, reducing its swaying or displacement in the thickness direction, thereby improving the stability of the assembled frame structure 1 in three-dimensional space. After the four splicing frame strips 11 are sequentially spliced ​​together to form a complete picture frame 100, the splicing frame strips 11 form a circumferential mutual restraint, preventing the locking protrusion 212a from sliding in the opposite direction along the opening of the slot 212b, thus reducing the risk of detachment under non-human operation. If disassembly is required, simply apply a reverse pulling force along the circumference of the picture frame 100, or use a special tool to pry open the anti-detachment limiting protrusion at the opening of the slot 212b, and the locking protrusion 212a can slide out of the slot 212b, making the operation convenient.

[0035] This mating structure of the latching protrusion 212a and the latching groove 212b achieves horizontal positioning through the interference / transition fit of the inner sidewalls of the latching protrusion 212a and the latching groove 212b. In the thickness direction, it relies on the clamping action of the two side walls of the splicing frame strip 11 to eliminate wobbling. In the circumferential direction, it achieves anti-disengagement locking through the structural restraint of the frame 100. Overall, this structure has reliable limiting capabilities in all three dimensions, and the assembly process only requires a linear push-in action in a single direction, eliminating the need for complex rotation or alignment operations, significantly reducing operational difficulty and improving assembly efficiency.

[0036] In some embodiments, please continue reading Figure 4 and Figure 5 To further optimize the fit between the protrusion 212a and the slot 212b, reduce assembly resistance, and improve structural stability after snap-fitting, both the outer surface of the protrusion 212a and the inner wall of the slot 212b are arc surfaces, and these arc surfaces are aligned along the thickness direction of the splicing frame strip 11 (which is perpendicular to the plane of the picture frame 100, such as...). Figure 1 (As shown by the dashed line N1). The arc-shaped surface design allows the contact area of ​​the protrusion 212a to gradually increase as it slides into the slot 212b, avoiding stress concentration and scratch damage caused by sharp edges.

[0037] Compared to planar contact, the arc surface fit can effectively reduce the frictional resistance when the locking protrusion 212a slides, making the assembly process smoother. After the locking is in place, the fit between the arc surfaces is tighter. Combined with the clamping effect of the two side walls of the splicing frame 11, it can further limit the wobble of the locking protrusion 212a in the thickness direction, improve the connection stability in three-dimensional space, and avoid loosening of the fit due to long-term use or slight vibration.

[0038] In some embodiments, in order to securely connect the snap-fit ​​component 21 to the inner side of the splicing frame strip 11 without affecting the normal engagement and operation of the snap-fit ​​part 212, the back side 2112 of the main body portion 211 of the snap-fit ​​component 21 is pasted to the splicing frame strip 11; wherein, the snap-fit ​​part 212 is formed on the front side 2111 of the main body portion 211.

[0039] Specifically, the splicing frame strip 11 is mostly U-shaped (including the bottom wall and two side walls). Its inner side is the side that adheres to the display device and is not exposed. The back side 2112 of the main body 211 of the snap-fit ​​part 21 is pasted to this inner side. This not only avoids the main body 211 being exposed and affecting the overall aesthetics of the frame 100, but also utilizes the enclosed space inside the splicing frame strip 11 to provide a certain degree of protection for the main body 211, reducing the impact of external force on the connection structure. High-temperature resistant and aging-resistant structural adhesive can be used for pasting, and the back side 2112 of the main body 211 should be completely adhered to the inner side wall of the splicing frame strip 11. If necessary, the bonding surface can be roughened to increase the contact friction and further improve the bonding firmness, ensuring that there is no relative displacement between the main body 211 and the splicing frame strip 11, providing a stable installation base for the snap-fit ​​part 212.

[0040] The snap-fit ​​part 212 is integrally formed on the front side 2111 of the main body part 211, that is, the side facing the display device and the adjacent splicing frame 11. This design allows the snap-fit ​​part 212 (snap protrusion 212a or slot 212b) to face the mating end of the adjacent splicing frame 11 for snap-fit.

[0041] Based on the distribution relationship between the protrusion 212a and the main body 211, and between the slot 212b and the main body 211, the embodiments of the present invention also provide a variety of layout schemes to adapt to different structural strengths and assembly requirements.

[0042] Optionally, the root of the latching protrusion 212a is connected to the corresponding main body 211 via a connecting arm 213, forming a gap 214 between the main body 211 and the latching protrusion 212a. The gap 214 allows the open side of the latching groove 212b to extend into it. This gap 214 design allows the open side of the latching groove 212b to be smoothly inserted, preventing the connection between the latching protrusion 212a and the main body 211 from obstructing the latching groove 212b. This ensures that the latching protrusion 212a can smoothly slide into the interior of the latching groove 212b, further reducing assembly resistance. At the same time, it also allows the latching protrusion 212a and the latching groove 212b to fit more tightly, improving the structural stability after latching and avoiding problems of insecure latching caused by assembly interference.

[0043] Optionally, the bottom of the slot 212b is connected to the corresponding main body 211. Direct connection of the bottom of the slot 212b to the main body 211 makes the structure of the slot 212b more compact, facilitating its arrangement within the limited cross-sectional space of the frame strip. Simultaneously, the bottom connection enhances the root strength of the slot 212b, making it less prone to deformation or breakage, thus improving the overall durability of the snap-fit ​​component 21.

[0044] Optionally, the main body 211 has a mating surface 2113. When two adjacent splicing frame strips 11 are spliced ​​together, the mating surfaces 2113 of the main bodies 211 of the two snap-fit ​​parts 21 fit together and abut. The fitting and abutting of the mating surfaces 2113 not only provides additional limiting support in the splicing direction and disperses the force on the snap-fit ​​parts 212, but also creates a seamless splicing effect visually, enhancing the overall aesthetics of the frame 100.

[0045] In some embodiments, please continue reading Figure 4 and Figure 5Considering that the snap-fit ​​component 21, after being installed inside the splicing frame strip 11, can be stably supported between the display device and the splicing frame strip 11, the main body 211 is adhered to the inner wall surface of the splicing frame strip 11. The snap-fit ​​component 21 also includes a support portion 215, which extends inward away from the splicing frame strip 11 to abut against the display device. The support portion 215 and the main body 211 can be integrally formed, and its extension length is adapted to the gap 214 between the inner side of the splicing frame strip 11 and the display device, ensuring that the support portion 215 can tightly abut against the surface of the display device, neither causing damage to the display device due to excessive extension nor failing to provide effective support due to insufficient extension. The design of the support part 215 serves two purposes. First, it provides auxiliary fixation for the snap-fit ​​part 21 itself, further enhancing the bonding stability between the main body 211 and the inner wall of the splicing frame 11, and preventing the snap-fit ​​part 21 from loosening or shifting due to external force or long-term use. Second, it provides flexible support for the picture frame 100 and the display device, filling the gap 214 between the splicing frame 11 and the display device, reducing the shaking between the display device and the picture frame 100, and dispersing the pressure of the picture frame 100 on the edge of the display device, preventing damage to the edge of the display device due to excessive local force, and further improving the overall stability and safety of use after the picture frame 100 and the display device are assembled.

[0046] Furthermore, the snap-fit ​​portion 212 and the support portion 215 of each snap-fit ​​component 21 are located at both ends of the main body 211 in the extension direction of the corresponding splicing frame strip 11. This layout design allows the snap-fit ​​portion 212 and the support portion 215 to be evenly distributed, avoiding uneven stress on the main body 211 caused by their concentrated placement, thereby preventing stress concentration, loosening and falling off at the bonding point between the main body 211 and the splicing frame strip 11; at the same time, the snap-fit ​​portion 212 is located at one end in the extension direction of the splicing frame strip 11, which can be aligned with the mating end of the adjacent splicing frame strip 11, making the snap-fit ​​operation smooth and without interference, while the support portion 215 is located at the other end, which can correspond to and fit the edge area of ​​the display device to form a stable support point. The two have clear division of labor and do not affect each other, taking into account both the snap-fit ​​firmness and the support stability.

[0047] In some embodiments, please refer to Figure 5 and Figure 6 Considering that many display devices have decorative strips at the bottom, such as televisions, which typically have a lower front shell decorative strip that protrudes from the display panel surface, creating a certain thickness difference, if the splicing frame strips 11 of the frame 100 adopt a uniform design, there will be assembly interference or uneven gaps 214 between the bottom frame strip and the decorative strip, affecting the overall aesthetics and assembly stability. Therefore, this embodiment of the invention specifically optimizes the structure of the bottom splicing frame strip 11 to fit the contour of the decorative strip at the bottom of the display device.

[0048] Specifically, the main body 211 has a break groove 216 formed at one end near the support 215, and the break groove 216 extends through the main body 211 along the thickness direction of the frame structure 1. The purpose of the break groove 216 is to remove the support 215. Of course, the support 215 can be removed or not to accommodate the thickness difference of the bottom decorative strip of the display device. When the bottom splicing frame 11 corresponds to the decorative strip area, the operator can break off and remove the support 215 along the break groove 216, so that the end of the main body 211 near the decorative strip forms a clearance space, avoiding interference between the support 215 and the protruding decorative strip. At this time, the main body 211 is still fixed to the inside of the splicing frame 11 by adhesive, the snap-fit ​​part 212 maintains its complete function, the splicing between adjacent frame strips is not affected, and the bottom frame strip after removing the support 215 can naturally fit against the surface of the decorative strip or form a uniform gap 214, ensuring the assembly coordination between the bottom of the frame 100 and the display device.

[0049] In scenarios where the support portion 215 needs to be removed, the rear sidewall of the bottom splicing frame 11 is typically lowered to allow the display device to pass through the rear sidewall and enter the interior of the splicing frame 11. Specifically, the height of the rear sidewall of the bottom splicing frame 11 is lower than the height of the rear sidewalls of the other three side splicing frame 11s, forming an open bottom entrance. This lowered rear sidewall, together with the main body 211 after the support portion 215 is removed, forms a clearance channel, allowing the decorative strip protruding from the bottom of the display device to pass smoothly through the bottom of the frame 100 and enter the interior space of the frame structure 1 without being blocked or squeezed by the bottom structure of the frame 100. After the display device is in place, its bottom decorative strip naturally hangs above the lowered rear sidewall or forms a uniform gap 214 with the front sidewall, ensuring both smooth assembly of the display device and the frame 100 and maintaining the integrity of the frame 100's appearance.

[0050] Correspondingly, the front sidewall of the bottom splicing frame 11 can maintain the same height as other frame strips to maintain the visual uniformity of the front 2111 of the picture frame 100.

[0051] The cross-sectional shape of the break groove 216 can be designed as a V-shaped, U-shaped, or rectangular groove. The groove depth can be controlled between one-third and one-half of the thickness of the main body 211, ensuring both ease of breaking operation and preventing excessive groove depth from weakening the structural strength of the main body 211. The position of the break groove 216 can be preset according to the thickness specifications of common display device decorative strips, for example, close to the root of the support 215, so that the operator can hold the support 215 and apply force to break it along the break groove 216, thus meeting the adaptation requirements of most models. For ordinary splicing frame strips 11 that do not require the removal of the support 215, the presence of the break groove 216 will not affect its support function; the support 215 can normally abut the display device while remaining intact.

[0052] In some embodiments, please refer to Figure 1 In order to more firmly fix the splicing frame 11 to the periphery of the display device and facilitate the disassembly and maintenance of the picture frame 100, the picture frame 100 is also equipped with a magnetic component 3, which is located on the inner side of the splicing frame 11 to attract the display device.

[0053] It is understandable that there are usually metal parts around the display device, such as the back panel bezel, middle frame or heat dissipation bracket, etc. These metal parts provide a reliable adsorption base for the magnetic part 3.

[0054] The magnetic attachment 3 uses adsorption force to tightly attach the splicing frame strip 11 to the display device, forming a synergistic effect with the physical support of the support part 215, doubly reinforcing the connection between the two, effectively preventing the splicing frame strip 11 from shifting or shaking around the display device, and ensuring the overall stability of the frame 100 after assembly; at the same time, the magnetic adsorption method does not require additional fasteners, and only a slight external force is needed to separate the frame 100 from the display device during disassembly, which is convenient and greatly reduces the difficulty of subsequent maintenance, replacement of the frame 100 or repair of the display device, truly achieving the dual requirements of "firm fixation" and "easy disassembly".

[0055] The magnetic connector 3 is installed in a concealed manner, adapting to the inner structure of the splicing frame 11. It is not exposed and does not affect the overall aesthetics of the frame 100. At the same time, it avoids the installation positions of the snap-fit ​​part 212 and the support part 215, thus preventing interference with the splicing operation and support function. The magnetic connector 3 can be installed in various ways, such as snap-fit, adhesive fixing, or screw fastening. It is preferably adapted to the pre-set installation groove on the inner side of the splicing frame 11 to achieve quick positioning and firm fixation.

[0056] The magnetic components 3 can be designed in the shape of a long strip or segmented small blocks. Multiple magnetic components 3 are spaced apart along the length of the inner side of each splicing frame strip 11, forming a distributed magnetic array. This ensures that the adsorption force is evenly distributed over the contact area between the splicing frame strip 11 and the display device, avoiding localized stress concentration or poor adhesion caused by single-point adsorption. The specific number of magnetic components 3 can be flexibly adjusted according to the length of the splicing frame strip 11, the weight of the display device, and the magnetic force specifications of the magnetic components 3. For example, three to four magnetic components 3 can be set for longer top and bottom frame strips, while two magnetic components 3 are sufficient for shorter side frame strips.

[0057] The magnetic attachment 3 typically faces the display device and can be covered with a flexible buffer layer, such as a silicone pad or foam, to increase the contact friction with the metal parts of the display device while avoiding surface scratches caused by hard contact.

[0058] When the frame 100 needs to be disassembled, the operator only needs to overcome the magnetic attraction and apply force outward in a direction perpendicular to the surface of the display device to remove the frame 100 as a whole. There is no need to use tools to tighten screws or pry open clips, which greatly simplifies the maintenance process and improves the user experience.

[0059] The present invention also provides a picture frame display device.

[0060] Please see Figures 1 to 6 The picture frame display device includes a display device and a picture frame 100 as described in any of the above embodiments. The display device is surrounded by the picture frame 100. The picture frame 100 is spliced ​​together by the snap-fit ​​structure of the snap-fit ​​component 21 and forms a stable connection with the display device through the support part 215 and the magnetic component 3.

[0061] Specifically, the display device can be an electronic device with a display panel, such as a television, monitor, or digital photo frame. The display device has a display panel and a surrounding bezel. The splicing frame strip 11 of the frame 100 surrounds the outer perimeter of the bezel. The inner side of the splicing frame strip 11 abuts against the surface of the bezel via a support 215, or is magnetically attached to the metal part of the bezel via a magnetic attachment 3, achieving a tight fit between the frame 100 and the display device. For display devices such as televisions with decorative strips at the bottom, the rear sidewall of the bottom splicing frame strip 11 of the frame 100 is lowered, and the support 215 is removed, allowing the decorative strip to smoothly enter the frame. The front sidewall of the frame 100 maintains the same height as the other frame strips, ensuring visual uniformity from the front.

[0062] This picture frame display device combines the decorative function of the picture frame 100 with the display function of the display device. The modular splicing structure of the picture frame 100 facilitates transportation, storage and on-site assembly. The cooperation between the protrusion 212a and the single-sided open slot 212b simplifies the assembly process. The dual fixing mechanism of the support part 215 and the magnetic part 3 ensures the overall structural stability and safety of the device. The flexible design of the break groove 216 enhances the adaptability of the picture frame 100 to different display device models, meeting diverse market demands.
