Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display device. Background Technology

[0002] With societal progress and commercial development, the use of display devices of various sizes for advertising and exhibitions has become commonplace. Furthermore, as people's demands for display devices increase—requiring not only practicality but also aesthetics—many existing display devices utilize different decorative frames (also known as picture frames) on their outer perimeter to achieve diverse visual effects, enhancing their appearance and improving the user experience. These picture frames typically include top and bottom frames, and left and right side frames.

[0003] Due to the limited internal space between the bottom frame and the left and right frames in related technologies, a small magnetic structure is typically used to connect the bottom frame and the left and right frames to fix the bottom frame to the bottom edge of the display device. However, the magnetic structure solution for fixing the bottom frame to the bottom edge of the display device has poor connection reliability and is prone to falling off, especially in complex and special user scenarios (such as accidental touches by children or customers carrying the device with the frame). Utility Model Content

[0004] This application discloses a display device that can effectively improve the installation reliability of the lower frame while meeting the requirements of miniaturized display device design, thereby reducing the probability of the lower frame falling off.

[0005] To achieve the above objectives, this application discloses a display device, the display device comprising:

[0006] A display device for displaying image information;

[0007] A decorative frame, which surrounds the outer periphery of the display device, and the decorative frame includes:

[0008] A sub-frame, wherein the sub-frame is disposed on the left edge and / or right edge of the display device, and the sub-frame extends vertically; and,

[0009] A lower frame, wherein the lower frame is disposed at the lower edge of the display device and extends in a left-right direction; and,

[0010] At least one interlocking structure, wherein the lower frame is connected to the sub-frame via the interlocking structure, and the interlocking structure includes:

[0011] A first connector, wherein the first connector is disposed at the end of the lower frame; and,

[0012] The second connector is disposed at the lower end of the sub-frame, and one of the second connector and the first connector is provided with a connector slot. The other of the first connector and the second connector includes a connector portion, which is inserted into the connector slot along the left-right direction.

[0013] Wherein, when the first plug-in component is provided with the plug-in groove, the first plug-in component is an annular structure forming the plug-in groove, and the peripheral sidewall of the annular structure in the vertical direction is connected to the lower frame.

[0014] When the first connector includes the connector portion, the first connector further includes a connecting portion that is angularly connected to the connector portion. The connector portion is disposed on the lower frame through the connecting portion. The connecting portion is located between the connector portion and the lower frame, and the projection of the connector portion on the lower frame covers the projection of the connecting portion on the lower frame.

[0015] In the display device provided in this application embodiment, by providing a first connector on the lower frame and a second connector on the sub-frame, one of the second connector and the first connector is provided with a connector slot, and the other includes a connector portion. Thus, the lower frame and the sub-frame can be installed and fixed by interlocking the connector portion and the connector slot. This can effectively improve the installation reliability of the lower frame and the sub-frame, thereby reducing the probability of the decorative frame falling off. At the same time, it can also limit the torsional deformation of the lower frame and the sub-frame, reducing the risk of the lower frame and the sub-frame torsion damaging the display device screen.

[0016] Meanwhile, when the first connector is provided with a connector groove, this application makes the first connector into an annular structure with a connector groove, and the peripheral sidewall of the annular structure is connected to the lower frame in the vertical direction. The groove sidewall used to form the connector groove is directly connected to the lower frame, and no additional mounting part is set to realize the connection between the first connector and the lower frame. This makes the overall structure of the first connector relatively simple and small, and occupies less space. It is suitable for solutions with limited internal space between the lower frame and the sub-frame.

[0017] When the first connector includes a connector portion, this application further includes a connecting portion that is angularly connected to the connector portion. The connector portion is disposed on the lower frame via the connecting portion, and the connecting portion is located between the connector portion and the lower frame. The projection of the connector portion on the lower frame covers the projection of the connecting portion on the lower frame, so that the space occupied by the connecting portion and the connector portion in the left and right directions overlaps. There is no need to reserve extra space in the left and right directions to set the connecting portion, so that the overall space occupied by the first connector is relatively small, which is suitable for solutions with limited internal space between the lower frame and the sub-frame.

[0018] In summary, by adopting the technical solution of this application, a first connector can be set in the limited space between the lower frame and the sub-frame, so that the lower frame and the sub-frame can be connected by a plug-in method, thereby effectively improving the installation reliability of the lower frame and the sub-frame and reducing the probability of the decorative frame falling off.

[0019] As an optional implementation, in the embodiments of this application, when the annular structure is disposed on the lower frame, the dimension of the peripheral sidewall of the annular structure in the left-right direction is L1, 16mm≤L1≤25mm;

[0020] When the above relationship is satisfied, it can ensure that the connection area between the ring structure and the lower frame is relatively large, which is conducive to improving the connection stability of the ring structure on the lower frame, and thus to improving the connection stability between the lower frame and the sub-frame, reducing the risk of the decorative frame falling off; at the same time, it can also avoid the ring structure being too large in the left and right directions, so that the overall volume of the plug-in structure can be relatively small, thus allowing the plug-in structure to be assembled in the limited internal space between the lower frame and the sub-frame.

[0021] When the plug-in part is set on the lower frame through the connecting part, the dimension of the plug-in part in the left-right direction is L2, 16mm≤L2≤25mm.

[0022] When the above relationship is satisfied, it ensures a large engagement amount between the connector and the slot, thus improving the connection stability between the lower frame and the sub-frame and reducing the risk of the decorative frame falling off. Simultaneously, it allows control over the lateral dimensions of the connector within a suitable range, reducing the risk of breakage during disassembly and shortening the insertion / removal distance, thereby improving the efficiency of assembling and disassembling the sub-frame. Furthermore, the overall size of the connector structure is relatively small, allowing it to be assembled within the limited internal space between the lower frame and the sub-frame.

[0023] As an optional implementation, in the embodiments of this application, the annular structure is a U-shaped structure with an opening.

[0024] Compared to a closed ring structure, the U-shaped structure with an opening reduces the obstruction of the ring structure on the connector during insertion into the slot, facilitating the insertion of the connector into the slot and enabling rapid assembly between the lower frame and the sub-frame. Furthermore, it allows the connector to be larger than the slot size, rather than requiring the connector size to be less than or equal to the slot size for insertion. This reduces the need for precise machining of the connector and lowers its manufacturing cost.

[0025] As an optional implementation, in the embodiments of this application, when the first connector is an annular structure with the connector groove, the annular structure includes a first part and a second part that are opposite to each other in the vertical direction, the first end of the first part and the second part are connected, the opening is formed between the second end of the first part and the second part, and the connector groove is formed between the first part and the second part.

[0026] The first part constitutes the peripheral sidewall connecting the annular structure and the lower frame. In the front-to-back direction, the size of the first part is larger than that of the second part. This allows for a larger contact area between the annular structure and the lower frame, thereby improving the connection stability of the annular structure on the lower frame, and consequently improving the connection stability between the lower frame and the sub-frame, reducing the risk of the lower decorative frame falling off.

[0027] This design reduces the obstruction of the interlocking part by the ring structure, making it easier to insert the interlocking part into the interlocking slot for quick assembly of the lower frame and the sub-frame. At the same time, it allows for a larger contact area between the ring structure and the lower frame, which improves the connection stability of the ring structure on the lower frame, thereby improving the connection stability between the lower frame and the sub-frame and reducing the risk of the lower decorative frame falling off.

[0028] As an optional implementation, in an embodiment of this application, one of the first connector and the lower frame is provided with a positioning hole, and the other of the first connector and the lower frame is provided with a positioning post, the positioning post being embedded in the positioning hole.

[0029] This configuration allows the first connector to be positioned on the lower frame by combining the positioning pin and the positioning hole during assembly. This enables the first connector to be quickly assembled at the target position on the lower frame, thus improving the assembly efficiency of the first connector.

[0030] As an optional implementation, in the embodiments of this application, there are at least three positioning holes and at least three positioning posts. The multiple positioning posts are arranged one-to-one with the multiple positioning holes, and the multiple positioning posts are respectively embedded in the corresponding positioning holes. By cooperating with the multiple positioning posts and the multiple positioning holes, the first connector can be prevented from rotating around the axial direction of the positioning post, which can achieve a better positioning effect and make the installation of the first connector on the lower frame more accurate and easier.

[0031] The positioning posts are arranged at intervals along the front-back direction, and at least two positioning posts are arranged at intervals along the left-right direction. In this way, the multiple positioning posts can form a planar reference, which can simultaneously constrain the plane directions of the multiple positioning posts (limiting the rotational degrees of freedom around the front-back and left-right directions), so that the first connector can be stably attached to the lower frame.

[0032] As an optional implementation, in the embodiments of this application, the first connector is fixed to the lower frame by adhesive bonding.

[0033] The connection between the first connector and the lower frame is achieved by bonding, which is a relatively simple method. Moreover, the bonding area between the two is relatively large, which can make the load evenly distributed across the entire bonding surface, avoiding point loads or local stress concentrations, and improving the fatigue life of the first connector and the lower frame.

[0034] Additionally, it is worth noting that when the first connector is an annular structure with a connector groove, compared to using fasteners such as screws or bolts to connect and fix the first connector and the lower frame, using adhesive bonding to connect and fix the first connector and the lower frame can avoid the fasteners such as screws or bolts from interfering with the connector by extending into the connector groove through the connection holes on the lower frame and the first connector, thus avoiding affecting the assembly of the connector and the connector groove.

[0035] As an optional implementation, in an embodiment of this application, the plug portion is provided with an elastic member on the surface in the vertical direction, the elastic member being deformed by the groove wall surface of the plug portion when the plug portion is inserted into the plug groove.

[0036] Therefore, when the plug and the elastic component are located in the plug groove, the elastic component is pressed between the plug and the groove wall and deforms. At this time, the elastic component also has the tendency to recover and pre-tighten the plug in the plug groove, thereby securing the plug in the plug groove. This improves the connection stability of the first plug and the second plug, which in turn improves the connection reliability between the lower frame and the sub-frame and reduces the chance of the decorative frame falling off.

[0037] As an optional implementation, in an embodiment of this application, the elastic member has a first end and a second end. The first end of the elastic member is disposed on the insertion portion, and the second end of the elastic member is bent toward the first end to be spaced apart from the first end in the vertical direction. In this way, the gap between the first end and the second end can be used to provide deformation for the elastic member, facilitating deformation of the elastic member when the insertion portion is inserted into the insertion slot. This makes it easier to insert the insertion portion into the insertion slot, thereby reducing the assembly difficulty of the first and second insertion components.

[0038] As an optional implementation, in the embodiments of this application, in the insertion direction of the plug-in portion into the plug-in groove, the distance between the second end and the first end is increased, and a guide surface is formed on the surface of the second end facing away from the first end;

[0039] The groove wall surface of the insertion slot facing the elastic member includes:

[0040] First step surface;

[0041] The second step surface and the first step surface are arranged along the insertion direction of the insertion part into the insertion slot. The second step surface and the first step surface have a height difference in the vertical direction, and the second step surface is closer to the insertion part than the first step surface.

[0042] An inclined surface is connected between the first step surface and the second step surface, and the inclined surface abuts against the guide surface.

[0043] This design allows the inclined surface and the guide surface to a certain extent to prevent the connector from detaching from the connector slot, thus reducing the risk of the connector easily detaching from the connector slot. At the same time, the inclined surface and the guide surface can also guide the connector out of the connector slot, reducing the difficulty of pulling the connector out of the connector slot.

[0044] As an optional implementation, in an embodiment of this application, the decorative frame further includes an upper frame disposed on the upper edge of the display device, the upper frame extending in the left-right direction;

[0045] The plug-in structure comprises at least two components. The lower frame and the sub-frame are connected via one of the plug-in structures, and the upper frame and the sub-frame are connected via the other plug-in structure. For example, the first plug-in component of the other plug-in structure is disposed on the upper frame, and the second plug-in component is disposed on the sub-frame.

[0046] In other words, the interlocking structure used between the upper frame and the sub-frame is the same as that used between the lower frame and the sub-frame. Therefore, during assembly, the upper and lower frames can be first assembled to the upper and lower edges of the display device, respectively. Then, the sub-frame is snapped into place along the left or right edge of the display device. At this point, the two interlocking parts in the vertical direction can be inserted into the interlocking slots in the horizontal direction to achieve a snap-locking effect for the entire decorative frame. It is evident that during assembly, the sub-frame only needs to move in one direction (left or right) to be fixedly assembled to the left or right edge of the display device. The movement trajectory of the sub-frame is relatively simple, making assembly more convenient and straightforward. Attached Figure Description

Detailed Implementation

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the exemplary embodiments of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments. That is, the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

[0065] It should be noted that the brief descriptions of terminology used in this application are merely for the purpose of facilitating understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0066] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0067] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first connector may be referred to as a second connector, and similarly, a second connector may be referred to as a first connector. Both the first connector and the second connector are connectors, but they are not the same connector.

[0068] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0069] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0071] In addition, the term "and / or" as used in this specification includes any and all combinations of the related listed items. For example, A and / or B can mean: A alone, A and B together, or B alone. That is, the term "and / or" as used in this specification includes any and all combinations of the related listed items.

[0072] With societal progress and commercial development, the use of display devices of various sizes for advertising and exhibitions has become commonplace. Furthermore, with the further development of communication and network technologies, remote medical consultations and teaching, remote business meetings, remote education, and consulting activities are becoming increasingly prevalent, leading to a wider application of corresponding display devices.

[0073] As people's demands for display devices increase, they require that these devices not only be practical but also aesthetically pleasing. Therefore, many existing display devices typically have different decorative frames (also known as picture frames) installed around their perimeter to achieve different visual effects, thereby improving the aesthetics of the display device and enhancing the user experience.

[0074] In related technologies, decorative frames are mainly installed on the edge of the display device using a magnetic structure to facilitate the installation of different decorative frames on the display device. However, the magnetic attachment method for decorative frames is not effective in dealing with complex and special user scenarios (such as accidental touches by children or customers carrying picture frames while moving the machine), and the decorative frames are prone to falling off.

[0075] In this regard, such as Figure 1 As shown, the applicant attempted to limit the first corner block 10 to the end of the upper frame 123, and the first corner block 10 has a limiting slot 101 with an open upper end; the second corner block 20 is limited to the upper end of the right frame, and a protruding limiting hook 201 is formed on the second corner block 20. The limiting hook 201 is engaged with the upper end of the first corner block 10, restricting the downward movement of the left and right decorative strips relative to the upper frame 123. At the same time, the limiting hook 201 is engaged in the limiting slot 101, restricting the movement of the second corner block 20 relative to the first corner block 10 in the left and right direction, and restricting the movement of the right frame relative to the upper frame 123 in the left and right direction. This can restrict the downward and left and right movement of the right frame, effectively preventing the right frame from falling, and thus effectively preventing the decorative frame 12 from falling, ensuring the reliability of the decorative frame 12.

[0076] But if Figure 1 As shown, the first corner block 10 typically includes a mounting portion 10a and a engaging portion 10b protruding from one side of the mounting portion 10a. A limiting slot 101 is formed on the engaging portion 10b. The mounting portion 10a extends into the fixing slot of the upper frame 123 to be fixed within the fixing slot of the upper frame 123. The engaging portion 10b and the mounting portion 10a are arranged in the left-right direction, so that both the engaging portion 10b and the mounting portion 10a need to reserve installation space in the left-right direction. As a result, the first corner block 10 can only be used if there is sufficient internal space in the left-right direction.

[0077] In related technologies, the width of the upper edge of a display device in the vertical direction is usually smaller than that of its lower edge. In order to improve the overall consistency and aesthetics of the decorative frame, it is usually necessary to widen the upper frame. Therefore, the upper frame has sufficient internal space in both the vertical and horizontal directions to install the first corner block. However, the internal space of the lower frame in the horizontal direction is relatively limited, as is the internal space between the lower frame and the left and right frames. This makes it common practice to use a small-space magnetic attraction structure to connect the lower frame and the left and right frames, so as to fix the lower frame to the lower edge of the display device.

[0078] However, as mentioned earlier, the magnetic attachment method lacks strong structural constraints, and the decorative frame is prone to falling off. Similarly, the solution of fixing the lower frame to the lower edge of the display device by magnetic structure also has poor connection reliability and is prone to falling off, especially when dealing with complex and special user scenarios (such as children accidentally touching the screen or customers carrying the frame while moving the machine).

[0079] In view of this, embodiments of this application provide a display device that can effectively improve the installation reliability of the lower frame while meeting the miniaturization design requirements of the display device, thereby reducing the probability of the lower frame falling off.

[0080] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0081] Please see Figure 2 , Figure 2 This is an exemplary structural diagram of a display device provided in an embodiment of this application. The display device 100 provided in this embodiment can be a television set or a computer monitor, etc.

[0082] In some embodiments, the display device 100 provided in this application may include a display device 11, which is used to display image information. The display device 11 may be, but is not limited to, a liquid crystal display (LCD) or an organic light-emitting diode display (OLED), or other display screens capable of displaying images. This application does not specifically limit the implementation of such displays.

[0083] Optionally, the display device 11 may be a plate-like structure, such as a rectangular plate-like structure, a square plate-like structure, etc. The display device 11 also has a thickness direction, a width direction, and a height direction.

[0084] like Figure 2 and Figure 3As shown, the display device 11 has a front side and a rear side arranged opposite to each other. The side of the display device 11 facing the user is the front side of the display device 11, and the distance from the rear side to the front side of the display device 11 is the thickness direction (i.e., the front-to-back direction) of the display device 11. The display device 11 also has a left side and a right side arranged opposite to each other. The distance from the left side to the right side of the display device 11 is the width direction (i.e., the left-to-right direction) of the display device 11. The display device 11 also has a top side and a bottom side arranged opposite to each other. The distance from the bottom side to the top side of the display device 11 is the height direction (i.e., the up-down direction) of the display device 11.

[0085] In some embodiments, the display device 11 may include a housing and a display panel. The display panel is fixed to the front side of the housing for displaying image information. The housing may include a back plate and a rear shell covering the back of the back plate. The display panel is disposed on the front side of the back plate. A light source and an optical film assembly may be disposed on the front side of the back plate. The light source, the optical film assembly, and the display panel are arranged sequentially from back to front. The light emitted by the light source is projected onto the display panel after passing through the optical film assembly. After the action of the display panel, image information is displayed on the display panel.

[0086] Other structures of the display device 11 can be referred to in the related art for the structure of the display device 11, and will not be described in detail here.

[0087] In some embodiments, such as Figure 2 and Figure 3 As shown, the display device 100 provided in this application embodiment also includes a decorative frame 12, which surrounds the outer periphery of the display device 11. For example, the decorative frame 12 is detachably snapped onto the four edges of the display device 11, thereby improving the aesthetics of the display device 11 and protecting the four edges of the display device 11.

[0088] In some embodiments, the decorative frame 12 may include a sub-frame 121, which is disposed on the left edge and / or right edge of the display device 11. That is, when there is one sub-frame 121, the sub-frame 121 is disposed on the left edge or right edge of the display device 11; and when there are two sub-frames 121, one sub-frame 121 is disposed on the left edge of the display device 11 and the other sub-frame 121 is disposed on the right edge of the display device 11.

[0089] In some embodiments, the sub-frame 121 may extend in the vertical direction, and the sub-frame 121 may be a strip-shaped structure. In the vertical direction, the end of the sub-frame 121 may extend beyond the end of the display device 11.

[0090] In some embodiments, the sub-frame 121 is detachably snapped onto the left and / or right edge of the display device 11 to facilitate the installation of the sub-frame 121 on the display device 11, thereby facilitating the snapping of sub-frames 121 with different structures or appearances onto the left and / or right edge of the display device 11.

[0091] In some embodiments, the decorative frame 12 may further include a lower frame 122, which is disposed at the lower edge of the display device 11, thereby protecting the lower edge of the display device 11.

[0092] In some embodiments, the lower frame 122 extends in the left-right direction and is a strip-shaped structure. In the left-right direction, the end of the lower frame 122 may extend beyond the end of the display device 11, and the end of the lower frame 122 may abut against the lower end of the sub-frame 121.

[0093] In some embodiments, the lower frame 122 is detachably engaged with the lower edge of the display device 11 to facilitate the installation of the lower frame 122 on the display device 11, thereby facilitating the engagement of lower frames 122 with different structures or appearances with the lower edge of the display device 11.

[0094] In some embodiments, such as Figure 3 and Figure 4 As shown, the display device 100 provided in this application embodiment further includes at least one plug-in structure 13, and the lower frame 122 is connected to the sub-frame 121 through the plug-in structure 13. The plug-in structure 13 includes a first plug-in member 131 and a second plug-in member 132. The first plug-in member 131 is disposed at the end of the lower frame 122, and the second plug-in member 132 is disposed at the lower end of the sub-frame 121. One of the second plug-in member 132 and the first plug-in member 131 is provided with a plug-in groove 1311, and the other of the second plug-in member 132 and the first plug-in member 131 is provided with a plug-in portion 1322. That is, when the second plug-in member 132 is provided with a plug-in groove 1311, the first plug-in member 131 is provided with a plug-in portion 1322, and when the second plug-in member 132 is provided with a plug-in portion 1322, the first plug-in member 131 is provided with a plug-in groove 1311. The plug-in portion 1322 is inserted into the plug-in groove 1311 in the left-right direction, thereby realizing the connection and fixation between the lower frame 122 and the sub-frame 121.

[0095] That is, by setting a first connector 131 on the sub-frame 121 and a second connector 132 on the lower frame 122, one of the second connector 132 and the first connector 131 is provided with a connector slot 1311 and the other includes a connector portion 1322. Thus, the lower frame 122 and the sub-frame 121 can be installed and fixed by interlocking the connector portion 1322 and the connector slot 1311. This can effectively improve the installation reliability of the lower frame 122 and the sub-frame 121, thereby reducing the probability of the decorative frame 12 falling off. At the same time, it can also limit the torsional deformation of the lower frame 122 and the sub-frame 121, reducing the risk of the lower frame 122 and the sub-frame 121 torsion damage to the screen of the display device 11.

[0096] like Figure 4 As shown, when the first connector 131 is provided with a connector groove 1311, the first connector 131 is an annular structure with the connector groove 1311, and the peripheral sidewall 1312 of the annular structure in the vertical direction is connected to the lower frame 122; thus, the groove sidewall used to form the connector groove 1311 is directly connected to the lower frame 122, and no additional mounting part is provided to realize the connection between the first connector 131 and the lower frame 122 (for example, Figure 1 The diagram shows a method for fixing the first corner block 10 by setting the mounting part 10a, which makes the overall structure of the first connector 131 relatively simple and small, and occupies less space, making it suitable for solutions with limited internal space between the lower frame 122 and the sub-frame 121.

[0097] like Figure 5 As shown, when the first connector 131 includes a connector portion 1322, the first connector 131 also includes a connecting portion 1321 that is angularly connected to the connector portion 1322. The connector portion 1322 is disposed on the lower frame 122 through the connecting portion 1321. The connecting portion 1321 is located between the connector portion 1322 and the lower frame 122, that is, the connector portion 1322 is located above the connecting portion 1321, and the projection of the connector portion 1322 on the lower frame 122 covers the projection of the connecting portion 1321 on the lower frame 122, so that the space occupied by the connecting portion 1321 and the connector portion 1322 in the left and right directions overlaps, and there is no need to reserve extra space in the left and right directions to set the connecting portion 1321. This makes the overall space occupied by the first connector 131 relatively small, which is suitable for schemes where the internal space between the lower frame 122 and the sub-frame 121 is limited.

[0098] In summary, by adopting the technical solution of this application, a first connector 131 can be provided in the limited space between the lower frame 122 and the sub-frame 121, so that the lower frame 122 and the sub-frame 121 can be connected by a plug-in method, thereby effectively improving the installation reliability of the lower frame 122 and the sub-frame 121 and reducing the probability of the decorative frame 12 falling off.

[0099] It should be explained in this application that the insertion part 1322 and the connecting part 1321 are connected at an angle, that is, an included angle is formed between them, the size of which can be approximately 90°. Understandably, during the production process, due to process factors such as equipment precision and measurement errors, the actual molding effect of the insertion structure 13 may be affected, so that the included angle between the insertion part 1322 and the connecting part 1321 may be approximately equal to 90°, such as 88°, 89°, 91° or 92°, etc.

[0100] In some embodiments, the first connector 131 can be assembled with the lower frame 122 as part of the material, and the second connector 132 can be assembled with the sub-frame 121 as part of the material, so that the user can use it immediately after unpacking. The lower frame 122 and the sub-frame 121 are assembled to the edge of the display device 11, which helps to improve the installation efficiency of the decorative frame 12.

[0101] In some embodiments, such as Figure 3 and Figure 6 As shown, the decorative frame 12 also includes an upper frame 123 disposed on the upper edge of the display device 11. The upper frame 123 extends in the left-right direction and may be a strip structure. In the left-right direction, the end of the lower frame 122 may extend beyond the end of the display device 11, and the end of the upper frame 123 may abut against the lower end of the sub-frame 121.

[0102] In some embodiments, the upper frame 123 is detachably engaged with the upper edge of the display device 11 to facilitate the installation of the upper frame 123 on the display device 11, thereby facilitating the engagement of upper frames 123 with different structures or appearances with the upper edge of the display device 11.

[0103] In some embodiments, there may be at least two plug-in structures 13, with the lower frame 122 and the sub-frame 121 connected by one plug-in structure 13, and the upper frame 123 and the sub-frame 121 connected by another plug-in structure 13. For example, the first plug-in member 131 of the other plug-in structure 13 is disposed on the upper frame 123, and the second plug-in member 132 is disposed on the sub-frame 121.

[0104] In other words, the plug-in structure 13 used between the upper frame 123 and the sub-frame 121 is the same as the plug-in structure 13 used between the lower frame 122 and the sub-frame 121. Therefore, during assembly, the upper frame 123 and the lower frame 122 can be assembled to the upper and lower edges of the display device 11 respectively, and then the sub-frame 121 can be snapped into the left or right edge of the display device 11 in the left-right direction. At this time, the two plug-in parts 1322 in the vertical direction can be inserted into the plug-in slots 1311 in the left-right direction to achieve the snap-locking of the entire decorative frame 12. It can be seen that during assembly, the sub-frame 121 only needs to move in the left-right direction to be fixedly assembled to the left or right edge of the display device 11. The movement trajectory of the sub-frame 121 is relatively simple, making assembly more convenient and simple.

[0105] It is understood that in other embodiments, the upper frame 123 and the sub-frame 121 can also be engaged and fixed using other snap-fit ​​structures, for example, by using... Figure 1 The first corner piece 10 and the second corner piece 20 shown in the diagram are engaged and fixed.

[0106] It should be noted that when there is one sub-frame 121, there can be two insertion structures 13. One insertion structure 13 is used to connect and fix the lower frame 122 and the sub-frame 121, and the other insertion structure 13 is used to connect and fix the upper frame 123 and the sub-frame 121. When there are two sub-frames 121, there can be four insertion structures 13. Two insertion structures 13 are used to connect and fix the lower frame 122 to the two sub-frames 121, and the other two insertion structures 13 are used to connect and fix the upper frame 123 to the two sub-frames 121. Alternatively, there may be three plug-in structures 13, with two plug-in structures 13 used to connect and fix the lower frame 122 to the two sub-frames 121, and the remaining plug-in structure 13 used to connect and fix the upper frame 123 to one of the sub-frames 121. Or, one plug-in structure 13 is used to connect and fix the lower frame 122 to one of the sub-frames 121, and the remaining two plug-in structures 13 are used to connect and fix the upper frame 123 to the two sub-frames 121.

[0107] like Figures 7 to 9 As shown, when the first connector 131 is an annular structure with a connector groove 1311, for ease of description, this application defines the dimension of the peripheral sidewall 1312 of the annular structure in the left-right direction as L1.

[0108] If L1 < 16mm, the connection area between the ring structure and the lower frame 122 is relatively small, which affects the connection stability of the ring structure on the lower frame 122, and thus affects the connection stability between the lower frame 122 and the sub-frame 121.

[0109] Therefore, in some embodiments, L1≥16mm, which ensures that the connection area between the annular structure and the lower frame 122 is relatively large, thereby improving the connection stability of the annular structure on the lower frame 122, which in turn improves the connection stability between the lower frame 122 and the sub-frame 121, and reduces the risk of the lower decorative frame 12 falling off.

[0110] If L1 > 25mm, the volume of the ring structure will be relatively small, resulting in a relatively large overall volume of the plug-in structure, making it difficult to assemble the plug-in structure 13 in the limited internal space between the lower frame 122 and the sub-frame 121.

[0111] Therefore, in some embodiments, L1≤25mm, which avoids the ring structure being too large in the left and right directions, so that the overall volume of the plug structure 13 can be relatively small, thereby enabling the plug structure 13 to be assembled in the limited internal space between the lower frame 122 and the sub-frame 121.

[0112] In some embodiments, 16mm ≤ L1 ≤ 25mm, for example, 16mm ≤ L1 ≤ 17mm, 17mm ≤ L1 ≤ 18mm, 18mm ≤ L1 ≤ 19mm, 19mm ≤ L1 ≤ 20mm, 21mm ≤ L1 ≤ 22mm, 22mm ≤ L1 ≤ 23mm, 23mm ≤ L1 ≤ 24mm, or 24mm ≤ L1 ≤ 25mm, etc. Exemplarily, L1 = 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 21mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm, or 25mm, etc.

[0113] When the above relationship is satisfied, it can ensure that the connection area between the ring structure and the lower frame 122 is relatively large, which is conducive to improving the connection stability of the ring structure on the lower frame 122, and thus conducive to the connection stability between the lower frame 122 and the sub-frame 121, reducing the risk of the decorative frame 12 falling off; at the same time, it can also avoid the ring structure being too large in the left and right directions, so that the overall volume of the plug-in structure 13 can be relatively small, so that the plug-in structure 13 can be assembled in the limited internal space between the lower frame 122 and the sub-frame 121.

[0114] like Figure 10 As shown, when the first connector 131 includes a connecting portion 1321 and a connector portion 1322 that is angularly connected to the connecting portion 1321, and the connector portion 1322 is disposed on the lower frame 122 through the connecting portion 1321, for ease of description, this application defines the bottom dimension of the connecting portion 1321 in the left-right direction as L2.

[0115] If L2 < 16mm, the engagement amount between the insertion part 1322 and the insertion slot 1311 is relatively small, which will affect the connection stability between the lower frame 122 and the sub-frame 121.

[0116] Therefore, in some embodiments, L2≥16mm, which can ensure a large amount of engagement between the plug 1322 and the plug groove 1311, thereby improving the connection stability between the lower frame 122 and the sub-frame 121 and reducing the risk of the decorative frame 12 falling off.

[0117] If L2 > 25mm, the size of the plug-in part 1322 in the left-right direction is too large. On the one hand, it not only forms a relatively long cantilever, which is prone to torsional deformation, causing the plug-in part 1322 to easily break during disassembly; it also results in a long insertion and removal distance, affecting the efficiency of disassembly and assembly. On the other hand, it will cause the first plug-in component to occupy a large space in the left-right direction, making the overall volume of the plug-in structure 13 relatively large, thus making it difficult to assemble the plug-in structure 13 in the limited internal space between the lower frame 122 and the sub-frame 121.

[0118] Therefore, in some embodiments, L2 ≤ 25mm, which allows the size of the plug portion 1322 in the left-right direction to be controlled within a suitable range, avoiding an excessively large size of the connecting portion 1321 in the left-right direction. On the one hand, this reduces the risk of the plug portion 1322 easily breaking during disassembly, and also shortens the insertion and removal distance of the plug portion 1322, improving the assembly and disassembly efficiency of the sub-frame 121. On the other hand, it makes the overall volume of the plug structure 13 relatively small, allowing the plug structure 13 to be assembled in the limited internal space between the lower frame 122 and the sub-frame 121.

[0119] In some embodiments, 16mm ≤ L2 ≤ 25mm. For example, 16mm ≤ L2 ≤ 17mm, 17mm ≤ L2 ≤ 18mm, 18mm ≤ L2 ≤ 19mm, 19mm ≤ L2 ≤ 20mm, 21mm ≤ L2 ≤ 22mm, 22mm ≤ L2 ≤ 23mm, 23mm ≤ L2 ≤ 24mm, or 24mm ≤ L2 ≤ 25mm, etc. Exemplarily, L2 = 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 21mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm, or 25mm, etc.

[0120] When the above relationship is satisfied, it ensures a large engagement amount between the insertion part 1322 and the insertion slot 1311, which is beneficial to the connection stability between the lower frame 122 and the sub-frame 121 and reduces the risk of the decorative frame 12 falling off. At the same time, it can also control the size of the insertion part 1322 in the left and right directions within a suitable range to reduce the risk of the insertion part 1322 easily breaking during disassembly, shorten the insertion and removal distance of the insertion part 1322, and thus improve the disassembly and assembly efficiency of the sub-frame 121. Furthermore, the overall volume of the insertion structure 13 is relatively small, and it can be assembled in the limited internal space between the lower frame 122 and the sub-frame 121.

[0121] In some embodiments, such as Figure 11 As shown, the insertion part 1322 has an elastic member 133 on its vertical surface. This elastic member 133 is deformed by the groove wall of the insertion groove 1311 when the insertion part 1322 is inserted into the insertion groove 1311. Thus, when the insertion part 1322 and the elastic member 133 are located in the insertion groove 1311, the elastic member 133 is pressed between the insertion part 1322 and the groove wall of the insertion groove 1311 and deforms. At this time, the elastic member 133 also has a tendency to recover, pre-tightening the insertion part 1322 in the insertion groove 1311, thereby firmly limiting the insertion part 1322 in the insertion groove 1311, improving the connection stability of the first insertion member 131 and the second insertion member 132, and thus improving the connection reliability between the lower frame 122 and the sub-frame 121, reducing the probability of the decorative frame 12 falling off.

[0122] In some embodiments, the elastic member 133 has a first end 133a and a second end 133b. The first end 133a of the elastic member 133 is disposed on the insertion portion 1322, and the second end 133b of the elastic member 133 is bent toward the first end 133a to be spaced apart from the first end 133a in the vertical direction. In this way, the gap between the first end 133a and the second end 133b can be used to provide deformation for the elastic member 133, which facilitates the deformation of the elastic member 133 when the insertion portion 1322 is inserted into the insertion groove 1311. This makes it easier to insert the insertion portion 1322 into the insertion groove 1311, thereby reducing the assembly difficulty of the first insertion member 131 and the second insertion member 132.

[0123] For example, the elastic member 133 may be a metal sheet, such as a steel sheet, an aluminum sheet, etc.

[0124] In some embodiments, the insertion direction in which the insertion portion 1322 is inserted into the insertion slot 1311 is, for example... Figure 11In the leftward direction, the distance between the second end 133b and the first end 133a increases, and a guide surface 133c is formed on the surface of the second end 133b facing away from the first end 133a. Moreover, the groove wall surface of the insertion slot 1311 facing the elastic member 133 includes a first step surface 1311a, a second step surface 1311b, and an inclined surface 1311c. The second step surface 1311b and the first step surface 1311a are arranged along the insertion direction of the insertion part 1322 into the insertion slot 1311. The second step surface 1311b and the first step surface 1311a have a height difference in the vertical direction, and the second step surface 1311b is closer to the insertion part 1322 than the first step surface 1311a. The inclined surface 1311c connects the first step surface 1311a and the second step surface 1311b, and the inclined surface 1311c abuts against the guide surface 133c.

[0125] This design allows the inclined surface 1311c and the guide surface 133c to a certain extent to prevent the insertion part 1322 from disengaging from the insertion slot 1311, thereby reducing the risk of the insertion part 1322 easily disengaging from the insertion slot 1311. At the same time, the inclined surface 1311c and the guide surface 133c can also guide the insertion part 1322 out of the insertion slot 1311, reducing the difficulty of pulling the insertion part 1322 out of the insertion slot 1311.

[0126] In some embodiments, the annular structure may be a U-shaped structure with an opening 1313. Compared to a closed annular structure, the U-shaped structure with an opening 1313 reduces the obstruction of the annular structure on the insertion part 1322 during the insertion of the insertion part 1322 into the insertion slot 1311, facilitating the insertion of the insertion part 1322 into the insertion slot 1311 and quickly completing the assembly between the lower frame 122 and the sub-frame 121. Simultaneously, the size of the insertion part 1322 can be larger than the size of the insertion slot 1311, rather than necessarily requiring the size of the insertion part 1322 to be less than or equal to the size of the insertion slot 1311 for insertion into the insertion slot 1311. This reduces the machining accuracy and cost of the insertion part 1322.

[0127] In some embodiments, such as Figure 11 and Figure 12As shown, when the first connector 131 is an annular structure with a connector groove 1311, the annular structure may include a first portion 131a and a second portion 131b opposite each other in the vertical direction. The first ends 133a of the first portion 131a and the second portion 131b are connected, wherein an opening 1313 is formed between the second ends 133b of the first portion 131a and the second portion 131b, and a connector groove 1311 is formed between the first portion 131a and the second portion 131b. The first portion 131a constitutes the peripheral sidewall 1312 connecting the annular structure to the lower frame 122. In the front-back direction, the size of the first portion 131a is larger than the size of the second portion 131b. This allows for a larger contact area between the annular structure and the lower frame 122, thereby improving the connection stability of the annular structure on the lower frame 122, and further improving the connection stability between the lower frame 122 and the sub-frame 121, reducing the risk of the lower decorative frame 12 falling off.

[0128] This design reduces the obstruction of the annular structure to the insertion part 1322, making it easier to insert the insertion part 1322 into the insertion slot 1311 to quickly complete the assembly between the lower frame 122 and the sub-frame 121. At the same time, it also allows for a larger contact area between the annular structure and the lower frame 122, thereby improving the connection stability of the annular structure on the lower frame 122, which in turn improves the connection stability between the lower frame 122 and the sub-frame 121, reducing the risk of the lower decorative frame 12 falling off.

[0129] In some embodiments, such as Figure 13 As shown, one of the first connector 131 and the lower frame 122 is provided with a positioning hole 1221, and the other of the second connector 132 and the lower frame 122 is provided with a positioning post 1314. That is, when the first connector 131 is provided with a positioning hole 1221, the lower frame 122 is provided with a positioning post 1314; and when the first connector 131 is provided with a positioning post 1314, the lower frame 122 is provided with a positioning hole 1221, wherein the positioning post 1314 is embedded in the positioning hole 1221.

[0130] With this configuration, when assembling the first connector 131, the positioning post 1314 and the positioning hole 1221 can be combined to position the first connector 131 on the lower frame 122, thereby quickly assembling the first connector 131 at the target position on the lower frame 122 and improving the assembly efficiency of the first connector 131.

[0131] It is worth noting that when the first connector 131 is an annular structure with a connector groove 1311, it is preferable to use a scheme in which the first connector 131 is provided with a positioning post 1314 and the lower frame 122 is provided with a positioning hole 1221. This can prevent the positioning post 1314 from extending into the connector groove 1311 through the positioning hole 1221 and interfering with the connector 1322, so as to avoid affecting the assembly of the connector 1322 and the connector groove 1311.

[0132] In some embodiments, there can be multiple positioning holes 1221 and positioning posts 1314, such as two, three, four, five, six, etc. Multiple positioning posts 1314 are configured one-to-one with multiple positioning holes 1221, and each positioning post 1314 is embedded in its corresponding positioning hole 1221. Through the one-to-one engagement of multiple positioning posts 1314 with multiple positioning holes 1221, the first connector 131 can be prevented from rotating axially around the positioning post 1314, resulting in better positioning and making the installation of the first connector 131 on the lower frame 122 more precise and easier.

[0133] As one embodiment, when there are at least three positioning posts 1314 and three positioning holes 1221, the multiple positioning posts 1314 can be arranged in a straight line at intervals along the front-back direction.

[0134] In another embodiment, when there are at least three positioning posts 1314 and at least three positioning holes 1221, the positioning posts 1314 are arranged at intervals along the front-back direction, and at least two positioning posts 1314 are arranged at intervals along the left-right direction. That is, the positioning posts 1314 are not arranged at intervals in a straight line along the front-back direction. In this way, the positioning posts 1314 can form a planar reference, which can simultaneously constrain the plane directions in which the positioning posts 1314 are located (restricting the rotational degrees of freedom around the front-back direction and the left-right direction), so that the first connector 131 is stably attached to the lower frame 122.

[0135] For example, there are three positioning posts 1314, which can be arranged in a roughly triangular pattern, such as an isosceles triangle or a right triangle. This forms a stable triangular support structure, which can distribute external forces to three support points, significantly reduce local stress concentration, and effectively resist bending moment and torsional deformation.

[0136] In some embodiments, the first connector 131 is fixed to the lower frame 122 by adhesive bonding, for example, by using double-sided adhesive. Adhesive bonding is used to connect and fix the first connector 131 and the lower frame 122. This connection method is relatively simple, and the adhesive area between the two is relatively large, allowing the load to be evenly distributed across the entire adhesive surface. This avoids point loads or localized stress concentrations, thereby improving the fatigue life of both the first connector 131 and the lower frame 122.

[0137] Additionally, it is worth noting that when the first connector 131 is an annular structure with a connector groove 1311, compared to using fasteners such as screws or bolts to connect and fix the first connector 131 and the lower frame 122, using adhesive bonding to connect and fix the first connector 131 and the lower frame 122 can avoid the fasteners such as screws or bolts from extending into the connector groove 1311 through the connection holes on the lower frame 122 and the first connector 131 and interfering with the connector part 1322, thereby avoiding affecting the assembly of the connector part 1322 and the connector groove 1311.

[0138] The technical features of the above embodiments can be combined in any way. For the sake of simplicity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0139] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
