Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a panel display device and its narrow bezel composite adapter structure. Background Technology

[0002] With increasingly demanding image quality requirements for display products, 4K UHD displays are being increasingly used, thus forming UHD panel display devices. However, 4K UHD panels have densely packed COF lines on the ground side, meaning the spacing between the COF lines is small. This makes it difficult for the structural components of the display device to incorporate structural features (such as insert assembly structures and snap-fit ​​assembly structures) between pairs of COF lines to secure the back cover. Existing back cover fixing methods often result in wider ground-side bezels and a thicker overall thickness for the display product, which contradicts the market's pursuit of narrow bezels, high screen-to-body ratios, and a slim and lightweight design. Utility Model Content

[0003] In view of this, the present invention provides a narrow bezel composite adapter structure, which can realize the design of a narrow bezel on the ground side of the panel display device, improve the screen ratio of the panel display device, and the thickness of the whole device will not be increased.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A narrow bezel composite adapter structure is applied to a panel display device, comprising: a module and a back cover, wherein the module includes: a module back plate, a module middle frame and multiple panel COF lines, and also includes an adapter component;

[0006] The adapter is assembled into the module frame and is located outside the multiple panel COF lines;

[0007] The rear shell is assembled to the adapter, and the adapter has an arc-shaped structure that is adapted to the arc-shaped structure of the rear shell. The first assembly structure of the adapter and the rear shell includes: a bone insertion assembly structure and a snap-fit ​​assembly structure.

[0008] The insert assembly structure is located between two adjacent panel COF lines and is distributed between the module frame and the adapter; the snap-fit ​​assembly structure is located outside the panel COF line and is distributed on the first edge of the adapter near the rear shell end.

[0009] Preferably, the adapter includes an adapter plate;

[0010] The first part of the adapter plate is recessed inward to form a first flat wall structure; wherein, the first part of the adapter plate is opposite to the area between two adjacent COF lines of the panel, and the inner wall of the first part of the adapter plate is tangent to the middle curved portion of the COF line of the panel.

[0011] The bone fitting assembly structure passes through the first part of the adapter plate and is located between the first part of the adapter plate and the module frame.

[0012] The snap-fit ​​assembly structure is located at the first edge of the adapter plate near the end of the rear shell.

[0013] Preferably, the bone insertion assembly structure includes:

[0014] A slot is formed in the first part of the adapter plate and extends through the first part of the adapter plate;

[0015] A rib disposed on the inner wall of the rear shell and used to pass through the slot and engage with the inner end face of the slot.

[0016] Preferably, the insert of the rear shell is used to engage with the inner end face of the lower edge of the slot;

[0017] The snap-fit ​​assembly structure includes:

[0018] A male buckle is disposed on the inner wall of the rear shell and is used to engage with the lower edge of the adapter plate.

[0019] Preferably, the second portion of the adapter plate is recessed inward to form a second flat wall structure; wherein the second portion of the adapter plate is adjacent to and perpendicular to the first portion;

[0020] The inner wall of the rear shell corresponding to the second part of the adapter plate is provided with a limiting block, which is used to contact and cooperate with the second part of the adapter plate.

[0021] Preferably, the first part of the adapter plate is assembled with the module frame, and the second assembly structure of the first part of the adapter plate and the module frame is located on one side of the insert assembly structure.

[0022] Preferably, the first part of the module frame between two adjacent COF lines of the panel is provided with an abutment block, which is used to contact the first part of the adapter plate;

[0023] The second assembly structure includes:

[0024] A first screw mounting hole is formed in the first part of the adapter plate and passes through the first part of the adapter plate;

[0025] An abutment block is formed in the middle frame of the module, and a second screw locking hole is concentrically distributed with the first screw locking hole; wherein the first screw locking hole and the second screw locking hole are fixed by screw locking.

[0026] Preferably, the abutment block is provided with a positioning post;

[0027] The first part of the adapter plate has a through positioning hole, which is used to cooperate with the positioning post.

[0028] Preferably, the adapter plate is a sheet metal part.

[0029] A panel display device includes a ground-side bezel structure, wherein the ground-side bezel structure is a narrow bezel composite adapter structure as described above.

[0030] As can be seen from the above technical solution, the narrow-bezel composite adapter structure provided by this utility model, by adding adapters to the outside of multiple panel COF lines, can transfer the insert assembly structure and the snap-fit ​​assembly structure, which are difficult to arrange simultaneously between the panel COF lines, to the adapter and the back shell. Furthermore, the adapter is designed as an arc-shaped structure that matches the arc-shaped structure of the back shell, so that the adapter and the arc-shaped structure of the back shell are arranged in parallel, avoiding the adapter occupying too much space between the multiple panel COF lines and the back shell. Additionally, the insert assembly structure is arranged on two panels. The COF lines are positioned between the panels and close to the module frame to avoid the insert assembly structure occupying space between the adapter and the back cover. The snap-fit ​​assembly structure is also placed on the outside of the COF lines of the panel and at the first edge of the adapter near the end of the back cover to avoid the snap-fit ​​assembly structure occupying too much space between the adapter and the back cover. In this way, the ground bezel is not too wide, which means that the design of the panel display device with a narrow ground bezel can be realized, thereby improving the screen ratio of the panel display device. Of course, with this design, the thickness of the whole device will not be increased, and it is also convenient to disassemble the back cover. Attached Figure Description

Detailed Implementation

[0048] In a prior art, such as Figure 12 As shown, the UHD panel display device with a bezel can be divided into several parts: module front bezel A21, module panel A, module backplate A23, module middle frame A24, and back shell A25. Due to the wide COF line spacing of module panel A, module backplate A23 has space for backplate slot A23-1 and backplate male clip A23-2, which respectively mate with the front bezel insert A21-1 and front bezel female clip A21-2 of module front bezel A21; simultaneously, space is also provided for the back shell insert B25-1 and back shell female clip B25-2 of back shell A25, which mate with the front bezel slot B21-3 and front bezel male clip B21-4 of module front bezel A21; Figure 12 It can be seen that the features used for assembling structural components can all be made in areas outside the COF lines of the panel;

[0049] However, the COF lines of the UHD panel are dense, and the space between each pair of COF lines is not enough to allow the back panel to grow a raised edge. Making a bridge edge may be easier to form, but the space is still not enough to make a plastic front frame or back shell A snap-fit ​​structure, which will reduce the overall strength of the back panel. Using an aluminum frame or plastic frame as the frame, the back is locked to the back panel, and the back shell A is snap-fitted to the aluminum frame or plastic frame, but this will make the whole machine thicker.

[0050] In another existing technology, such as Figure 13As shown, the UHD panel borderless display device can be divided into several parts: module front frame B31, module panel B32, module back plate B33, module middle frame B34, and back shell B35. Among them, module panel B32, module back plate B33, and module middle frame B34 can be regarded as a whole. Due to the narrow spacing of the COF lines B32-1 on the panel, the module back plate B can only act as a bridge structure. The screw fixing surface 33-1 of the back plate is locked together with the screw fixing position 31-1 of the front frame by screws B36. Then, the back shell B35 is fixed to the module front frame B by adhesive or clips. However, although this solves the problem of the narrow space of the COF lines making it difficult to construct a structure, if the back shell B is made by adhesive, it will make the whole machine difficult to disassemble. If the snap-fit ​​method is used, it will increase the thickness of the whole machine significantly. It is difficult to achieve ultra-narrow bezel, ultra-thin body, and easy disassembly at the same time.

[0051] Therefore, a structural solution is needed that simultaneously addresses the issues of wide bezels, thick bodies, and difficulty in disassembly of panel display devices (such as UHD panel display devices). The ultra-narrow bezel composite adapter structure provided in this solution is such a structural solution.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] The narrow bezel composite adapter structure provided in this embodiment of the utility model is applied to panel display devices, such as... Figure 1 As shown, it includes: a module and a back cover 1. The module includes: a module back plate 2, a module middle frame 3 and multiple panel COF lines 4. The narrow bezel composite adapter structure also includes an adapter.

[0054] like Figure 2 As shown, the adapter is assembled on the module frame 3 and is located on the outside of multiple panel COF lines 4;

[0055] like Figure 3 As shown, the rear shell 1 is assembled to the adapter, and the adapter has an arc-shaped structure that is compatible with the arc-shaped structure of the rear shell 1. The first assembly structure of the adapter and the rear shell 1 includes: a bone-insertion assembly structure and a snap-fit ​​assembly structure.

[0056] The insert assembly structure is located between two adjacent panel COF lines 4 and is distributed between the module frame 3 and the adapter; the snap-fit ​​assembly structure is located outside the panel COF line 4 and is distributed on the first edge of the adapter near the end of the rear shell 1.

[0057] It should be noted that the aforementioned narrow bezel composite adapter structure can be used for the ground bezel composite adapter structure of a panel display device with relatively dense COF lines. This panel display device can be a UHD (4K) panel display device, or it can be a QHD (2K) panel display device. The initial intention behind this solution is that, considering the small COF line spacing of UHD panels, the portion of the module frame 3 between the two panel COF lines 4 lacks sufficient space for shaping and for arranging the insert assembly structure and the snap-fit ​​assembly structure; where, for example... Figure 1 As shown, the COF lines 4 of the UHD panel are very close together. The distance between the COF lines 4 of the panel cannot be like the COF line width spacing of other traditional UHD panels. At the same time, a snap-fit ​​assembly structure and a reverse insertion assembly structure can be made to restrict the XYZ direction freedom of the back shell and achieve the effect of fixing the back shell. Moreover, if the snap-fit ​​assembly structure and the reverse insertion assembly structure are made into one piece, although the space can be arranged, it is difficult to disassemble.

[0058] Therefore, it is necessary to add an adapter to fix the module frame 3. The insufficient space on the module frame 3 can be used to connect with the adapter. The structural features related to the assembly of the back shell 1 (such as the snap-fit ​​assembly structure and the insert assembly structure) can be made on the adapter. In short, the available space is expanded by the adapter. The snap-fit ​​assembly structure, which cannot be placed in the two assembly structures at the same time between the panel COF lines 4, is moved to the outside of the panel COF lines 4. The insert assembly structure is arranged between the two panel COF lines 4, so that the snap-fit ​​assembly structure does not have to be squeezed into the small space between the UHD panel COF lines with the insert assembly structure. Moreover, the separate arrangement of the insert assembly structure and the snap-fit ​​assembly structure allows the back shell 1 to have room for deformation, which facilitates the free disassembly of the back shell 1.

[0059] Considering that the spaced COF lines 4 on the panel cannot provide a large continuous structure for fixing to the back shell 1, and that the adapter is installed after the COF lines 4 on the panel are installed, such as Figure 1 As shown, the adapter can be a long strip structure, which provides space for fixing it to the rear shell 1, such as... Figure 2 As shown, the adapter can also cover multiple panel COF lines 4, thus protecting them. Of course, the insert assembly structure, which poses a greater risk to the panel COF lines 4, is arranged in the area between the panel COF lines 4 to avoid scratching them. The snap-fit ​​assembly structure, which poses a less risk to the panel COF lines 4, can be arranged on the outside of the panel COF lines 4 to facilitate the snap-fit ​​between the back cover 1 and the adapter.

[0060] like Figure 1As shown, the adapter can be secured to multiple first portions of the module frame 3 by multiple screws 7; wherein, the first portion of the module frame 3 is the portion between two adjacent panel COF lines 4; and as mentioned above, the adapter can be a long strip structure and can cover the outside of the multiple panel COF lines 4; wherein, as Figure 1 As shown, the adapter can cover the outside of the six panel COF lines 4;

[0061] like Figure 3 As shown, the end of the back cover 1 near the module panel 6 has an arc-shaped structure; that is, the end of the back cover 1 has an arc-shaped structure. Figure 5 As shown, the adapter also has an arc-shaped structure, such as... Figure 7 As shown, the arc-shaped structure of the adapter is adapted to the arc-shaped structure at the end of the rear shell 1. This allows the shape of the adapter to match the shape of the end of the rear shell 1, thus making the adapter and the end of the rear shell 1 parallel. This avoids the adapter occupying too much space between the module frame 3 and the rear shell 1, and avoids the ground bezel of the UHD panel display device being too wide.

[0062] The rear shell 1 is assembled and fixed to the adapter via a insert assembly structure (i.e., a snap-fit ​​assembly structure) and a snap-fit ​​assembly structure (i.e., a fastening assembly structure). The insert assembly structure is located between two adjacent panel COF lines 4 and is distributed between the module frame 3 and the adapter, thus avoiding space occupation between the adapter and the rear shell 1. The snap-fit ​​assembly structure is located outside the panel COF lines 4 and is distributed on the first edge of the adapter near the end of the rear shell 1, thus avoiding excessive space occupation between the adapter and the rear shell 1. This arrangement of the insert assembly structure and the snap-fit ​​assembly structure further avoids excessive bezel length on the ground side of the UHD panel display device. The width allows for a narrow bezel on the ground side without increasing the overall thickness of the device. To ensure a tighter fit between the rear shell 1 and the adapter, multiple insert assembly structures and snap-fit ​​assembly structures can be used. These multiple insert assembly structures correspond one-to-one with multiple first parts of the module's frame 3, and multiple snap-fit ​​assembly structures are located one-to-one on the outer side of multiple panel COF lines 4. Furthermore, to further narrow the ground side bezel, the adapter can be made from thin sheet metal through sheet metal stamping, minimizing its wall thickness while maintaining structural strength. This results in a smaller footprint and higher strength compared to plastic or aluminum alloy parts.

[0063] In other words, the narrow-bezel composite adapter structure provided in this solution, by adding adapters on the outside of multiple panel COF lines, can transfer the insert assembly structure and the snap-fit ​​assembly structure, which are difficult to arrange simultaneously between the panel COF lines 4, to the adapter and the back shell. Furthermore, the adapter is designed as an arc-shaped structure that adapts to the arc-shaped structure of the back shell, ensuring that the adapter and the arc-shaped structure of the back shell are distributed in parallel, avoiding the adapter occupying too much space between the multiple panel COF lines 4 and the back shell. Additionally, the insert assembly structure is arranged between two panel COF lines 4. Furthermore, the mounting structure is positioned close to the module frame to avoid the insertion assembly structure occupying space between the adapter and the back cover. The snap-fit ​​assembly structure is also placed on the outside of the COF line 4 of the panel and at the first edge of the adapter near the end of the back cover, thus avoiding the snap-fit ​​assembly structure occupying too much space between the adapter and the back cover. In this way, the ground bezel is avoided from being too wide, which means that the ground bezel design of the UHD panel display device can be realized, thereby improving the screen ratio of the UHD panel display device. Of course, with this design, the thickness of the whole machine will not be increased, and it is also convenient to disassemble the back cover.

[0064] In this plan, such as Figure 1 As shown, the adapter includes an adapter plate 5;

[0065] The first part of the adapter plate 5 is recessed inward to form a first flat wall structure; wherein, the first part of the adapter plate 5 is opposite to the area between two adjacent panel COF lines 4, and the inner wall of the first part of the adapter plate 5 is tangent to the middle curved part of the panel COF line 4.

[0066] The insert assembly structure passes through the first part of the adapter plate 5 and is located between the first part of the adapter plate 5 and the module frame 3.

[0067] The snap-fit ​​assembly structure is located at the first edge of the adapter plate 5 near the end of the rear shell 1.

[0068] It should be noted that the first part of the adapter plate 5 is distributed opposite to the first part of the module frame 3 mentioned above, that is, the first part of the adapter plate 5 is parallel to the first part of the module frame 3. When the UHD panel display device is placed vertically, the first part of the adapter plate 5 can be a flat structure, and its inner wall is tangent to the outer wall of the middle curved portion of the panel COF line 4. The insert assembly structure passes through the first part of the adapter plate 5 and is located between the first part of the adapter plate 5 and the module frame 3, making the insert assembly structure more compact than the middle curved portion of the panel COF line 4. The outer wall of the curved section is closer to the module frame 3, which avoids the insert assembly structure occupying the space between the adapter and the rear shell 1; of course, as mentioned above, the adapter plate 5 can be made of thin sheet metal through sheet metal stamping; the snap-fit ​​assembly structure can be located at the first edge of the adapter plate 5 near the end of the rear shell 1, so that the snap-fit ​​assembly structure does not occupy too much space between the adapter plate 5 and the rear shell 1; of course, the rear shell 1 is actually snapped into the first edge of the adapter plate 5 through the snap-fit ​​assembly structure; in addition, as mentioned above, the number of insert assembly structures can be multiple, such as Figure 1 As shown, the number of first parts of the adapter plate 5 is also multiple, and multiple insert assembly structures are distributed in multiple first parts of the adapter plate 5.

[0069] In other words, the first part of the adapter plate 5 is recessed towards the module middle frame 3 to form a first flat wall structure. This not only allows the bone assembly structure to be closer to the module middle frame 3, avoiding an excessively wide side frame, but also facilitates screw fastening and fixing of the adapter plate 5 and the first part of the module middle frame 3.

[0070] Specifically, such as Figure 2 and Figure 3 As shown, the bone graft assembly structure includes:

[0071] A slot 5-1 is provided in the first part of the adapter plate 5 and passes through the first part of the adapter plate 5;

[0072] The insert 1-1 is disposed on the inner wall of the rear shell 1 and is used to pass through the slot 5-1 and engage with the inner end face of the slot 5-1.

[0073] It should be noted that the structure of slot 5-1 in the first part of adapter board 5 can be referred to as... Figure 5 As shown, it can be a square slot; the insert 1-1 on the inner wall of the rear shell 1, the structure of which can be referred to Figure 4 As shown, it can be a hook structure; wherein, the insert 1-1 passes through the slot 5-1 and is snapped into the inner end face of the slot 5-1 (i.e., the inner wall of the first part of the adapter plate 5), realizing the snapping of the rear shell 1 and the adapter plate 5, used to hold the end of the rear shell 1 and prevent the end of the rear shell 1 from coming off outward; and as Figure 3As shown, the insert 1-1 can be snapped into the inner end face of the lower edge of the slot 5-1; of course, the insert assembly structure is designed in this way, which not only facilitates the snapping of the end of the rear shell 1 with the first part of the adapter plate 5, but also facilitates the distribution of the insert 1-1 in the insert assembly structure close to the module frame 3.

[0074] Furthermore, such as Figure 8 As shown, the insert 1-1 of the rear shell 1 is used to engage with the inner end face of the first edge of the slot 5-1 near the end of the rear shell 1.

[0075] The snap-fit ​​assembly structure includes:

[0076] Male buckle 1-2 is disposed on the inner wall of the rear shell 1 and is used to engage with the first edge of the adapter plate 5.

[0077] It should be noted that, as Figure 5 As shown, the first edge of slot 5-1 can be the lower edge of slot 5-1, that is, the edge near the end of the rear shell 1, as shown. Figure 3 and Figure 9 As shown, the insert 1-1 of the rear shell 1 can be engaged with the inner end face of the lower edge of the slot 5-1 (i.e., the inner wall of the first part of the adapter plate 5), thus achieving the first limiting of the rear shell 1. Moreover, as mentioned above, the insert 1-1 can be a hook structure, and after passing through the slot 5-1, it can be engaged with the inner end face of the lower edge of the slot 5-1; Figure 3 As shown, the first edge of the adapter plate 5 can be the lower edge, such as... Figure 3 and Figure 10 As shown, the male buckle 1-2 on the inner wall of the rear shell 1 can be used to engage with the lower edge of the adapter plate 5, thus achieving a second limiting on the rear shell 1. Furthermore, a portion of the male buckle 1-2 can be located between the COF line 4 of the panel and the adapter plate 5, while another portion is located between the adapter plate 5 and the rear shell 1. Figure 3 As shown, the first edge of the adapter plate 5 may have a groove, which serves as a female buckle 5-4 that mates with the male buckle 1-2. Furthermore, since the insert assembly structure and the buckle assembly structure are set separately, the rear shell 1 has a certain deformation space. Thus, even if the insert 1-1 and the male buckle 1-2 of the rear shell 1 interfere with each other during installation, the deformation of the rear shell 1 ensures that both the insert 1-1 and the male buckle 1-2 can be installed in place, preventing the rear shell 1 from failing to install the adapter plate 5 through the insert assembly structure and the buckle assembly structure. Of course, when the UHD panel display device is placed vertically, the first edge of the slot 5-1 is not the lower edge, but can be the front edge. Similarly, the first edge of the adapter plate 5 is not the lower edge, but can be the front edge. Moreover, the snap-fit ​​engagement between the insert 1-1 and the slot 5-1 helps to hold the end of the rear shell 1 to prevent it from falling off, and the buckle 1-2 engaging with the first edge of the adapter plate 5 effectively helps to hold the end of the rear shell 1 to prevent it from falling off backward.

[0078] When assembling the rear shell 2 with the adapter plate 5, the insert 1-1 of the rear shell 1 is first inserted into the slot 5-1 of the adapter plate 5 as a guide and a limit in a certain direction. As the insert 1-1 is continuously inserted, the male buckle 1-2 of the rear shell 1 gradually contacts the first edge of the adapter plate 5 and finally snaps into place, achieving a limit in another direction. After the insert 1-1 and the male buckle 1-2 are installed in place, the rear shell 2 and the adapter plate 5 can be firmly fixed together.

[0079] Furthermore, such as Figure 1 As shown, the second part of the adapter plate 5 is recessed inward to form a second flat wall structure; wherein, the second part of the adapter plate 5 is adjacent to and perpendicular to the first part;

[0080] like Figure 3 As shown, the inner wall of the rear shell 1 corresponding to the second part of the adapter plate 5 is provided with a limiting block 1-3, which is used to contact and cooperate with the second part of the adapter plate 5.

[0081] It should be noted that, as Figure 2 As shown, the second part of the adapter plate 5 is not only adjacent to and perpendicular to the first part, but also perpendicular to the first part of the module frame 3; wherein, as Figure 5 As shown, the first part of the adapter plate 5 can be the vertical sidewall of the adapter plate 5, and the second part can be the horizontal top wall of the adapter plate 5, adjacent to the vertical sidewall; as Figure 3 As shown, the inner wall of the rear shell 1 corresponding to the second part of the adapter plate 5 can be provided with several limiting blocks 1-3, which are used to contact and cooperate with the second part of the adapter plate 5, so that the inner wall of the rear shell 1 and the second part of the adapter plate 5 can be supported and limited, which can prevent the part of the rear shell 1 corresponding to the second part of the adapter plate 5 from shaking after assembly; of course, when the UHD panel display device is placed vertically, the above design can limit the rear shell 1 forward. Among them, as Figure 4 As shown, there can be two limiting blocks 1-3, both of which can be close to a right-angled triangle structure, and one right-angled edge of the limiting block 1-3 is used for contact and engagement with the second part of the adapter plate 5. Furthermore, there can be multiple second parts of the adapter plate 5, corresponding one-to-one with multiple first parts, and the number of limiting blocks 1-3 will also be multiple accordingly. Additionally, to ensure that the rear shell 1 is stably assembled onto the adapter plate 5, similarly, as... Figure 3 As shown, a small limiting block can also be provided between the third part of the adapter plate 5 and the inner wall of the rear shell 1 to support and limit the third part of the adapter plate 5 and the inner wall of the rear shell 1, so as to better prevent the rear shell 1 from shaking during assembly; wherein, the third part of the adapter plate 5 is the part away from its first edge and can be distributed collinearly with the second part.

[0082] In this design, the first part of the adapter plate 5 is assembled with the module frame 3, and the second assembly structure of the first part of the adapter plate 5 and the module frame 3 is located on one side of the insert assembly structure. Specifically, multiple first parts of the adapter plate 5 are assembled and connected one-to-one with multiple first parts of the module frame 3.

[0083] In other words, the adapter plate 5 and the module frame 3 have multiple second assembly structures, each located on one side of multiple insert assembly structures. That is, each second assembly structure of the adapter plate 5 and the module frame 3 and each insert assembly structure are located together between two adjacent panel COF lines 4. This not only avoids assembly interference between the adapter plate 5 and multiple panel COF lines 4, but also makes the frame structure more compact.

[0084] Specifically, such as Figure 6 As shown, the first part of the module frame 3 between two adjacent panel COF lines 4 is provided with an abutment block 3-1, which is used to contact the first part of the adapter plate 5.

[0085] like Figure 5 and Figure 6 As shown, the second assembly structure includes:

[0086] A first screw mounting hole 5-2 is formed in the first part of the adapter plate 5 and passes through the first part of the adapter plate 5;

[0087] An abutment block 3-1 is formed in the middle frame 3 of the module, and a second screw locking hole 3-2 is concentrically distributed with the first screw locking hole 5-2; wherein the first screw locking hole 5-2 and the second screw locking hole 3-2 are locked and fixed by screws 7.

[0088] It should be noted that the abutment block 3-1 provided in the first part of the frame 3 in the module is used to contact and cooperate with the inner wall of the first part of the adapter plate 5, which can realize the assembly limit of the adapter plate 5; such as Figure 5 As shown, the first screw mounting hole 5-2 penetrates the first part of the adapter plate 5 and can be a through hole for the screw 7; as Figure 6 As shown, the second screw locking hole 3-2 is opened on the abutment block 3-1 of the module frame 3 and is concentrically distributed with the first screw locking hole 5-2, so that the screw 7 can lock and fix the first screw locking hole 5-2 of the first part of the adapter plate 5 and the second screw locking hole 3-2 of the module frame 3, thereby realizing the assembly and fixation of the adapter plate 5 and the module frame 3.

[0089] In other words, each first part of the adapter plate 5 can be locked and fixed to the corresponding first part of the module frame 3 by screws 7, thus achieving side locking of the adapter plate 5. This makes the assembly of the adapter plate 5 and the module frame 3 simple, convenient, and reliable; among which, such as Figure 5 As shown, the first part of the adapter plate 5 can serve as the adapter plate fixing position 5-5; of course, as Figure 11 As shown, screw 7 can be further secured to the module backplate 2; and as Figure 2 As shown, the second part of the adapter plate 5 at its end can also be locked and fixed to the module back plate 2 by screws 7, thus realizing the back locking of the adapter plate 5. Of course, the second assembly structure can also be a snap-fit ​​assembly structure or a plug-in assembly structure, which will not be described in detail here.

[0090] Furthermore, such as Figure 2 As shown, the abutment block 3-1 is provided with a positioning post 3-3;

[0091] The first part of the adapter plate 5 has a through positioning hole 5-3, which is used to cooperate with the positioning post 3-3.

[0092] In other words, a mutually cooperating positioning and assembly structure is provided between the module frame 3 and the adapter plate 5, including the aforementioned mutually cooperating positioning posts 3-3 and positioning holes 5-3, which enables the adapter plate 5 to be positioned and assembled on the module frame 3, thereby allowing the adapter plate 5 to be quickly and accurately assembled on the module frame 3. For example, Figure 2 As shown, there can be multiple positioning posts 3-3, each positioned on multiple abutment blocks 3-1. Similarly, there can be multiple positioning holes 5-3, each engaging with one of the positioning posts 3-3. This allows the adapter plate 5 to be positioned and assembled on the module frame 3 at multiple points, better ensuring the accuracy of the adapter plate 5 assembly. Of course, other positioning and assembly structures can also be used between the module frame 3 and the adapter plate 5, such as mutually engaging positioning protrusions and positioning grooves, which will not be elaborated upon here.

[0093] Furthermore, such as Figure 5 As shown, the adapter plate 5 is a sheet metal part. As mentioned above, the adapter plate 5 can be made by sheet metal stamping of a long strip of thin plate. In this way, the adapter plate 5 can be a one-piece structure with high structural strength, which can protect the COF line 4 of the panel from damage by the male clips 1-2. Moreover, the adapter plate 5 can be a thin-walled part, which can enable the ground side frame to achieve a narrow frame design.

[0094] In summary, such as Figure 1As shown, this ultra-narrow bezel composite adapter structure includes: a module, an adapter plate 5, screws 7, and a back cover 1; the module further includes: a panel COF line 4, a module back plate 2, and a module middle frame 3; during assembly, the panel COF line 4, the module back plate 2, and the module middle frame 3 are first fixed together as the module part, then the adapter plate 5 is fastened to the module middle frame with screws 7. The screws can be side-locked or back-locked, and the screws are fastened to the module in the space between the two panel COF lines. Finally, the back cover 1 is assembled and fixed to the adapter plate 5 through a snap-fit ​​assembly structure and a rib assembly structure; the rib assembly structure is located between the two panel COF lines, sharing this narrow space with the screws, and the male snaps 1-2 of the back cover are on the outside of the panel COF line and engage with the female snaps on the adapter plate; of course...

[0095] The proposed ultra-narrow bezel composite adapter structure also solves the following problems:

[0096] 1. The limited space between COF lines on the panel prevents the simultaneous placement of reverse inserts and clips;

[0097] 2. The snap-fit ​​and reverse insertion bone are integrated into a single structure, making them difficult to disassemble;

[0098] 3. The fasteners located in the COF line area of ​​the panel are prone to damaging the COF line of the panel;

[0099] 4. The space occupied by the snap-fit ​​reverse insert results in a wide and thick frame for the entire machine.

[0100] Furthermore, this utility model embodiment also provides a panel display device, including a ground-side bezel structure, which is the narrow bezel composite transition structure described above. Since this solution adopts the aforementioned narrow bezel composite transition structure, it has corresponding beneficial effects, as detailed above, and will not be repeated here. The aforementioned panel display device can be a panel display device with relatively dense COF lines, and can be a UHD (4K) panel display device. A UHD panel display device can be a UHD panel borderless display device; of course, it can also be a QHD (2K) panel display device.
