Description

Technical Field

[0001] This disclosure relates to the field of display bezel technology, and more particularly to display bezel self-locking components and display devices. Background Technology

[0002] In today's increasingly competitive color TV market, ultra-thin and ultra-narrow bezels and high screen-to-body ratios have become core selling points for brands to attract consumers, while also meeting the public's aesthetic demands for product appearance.

[0003] Currently, there are two main methods for fixing TV bezels. The first is the snap-on spring clip method, which uses metal spring clips as the connection medium between the bezel and the back panel. The spring clips achieve fixation through elastic deformation. However, the metal spring clips occupy width space, increasing the bezel width and preventing the achievement of an ultra-narrow design, while also increasing material costs. The second method is the back-locking screw method, which uses screws to fix the back panel embedded in the bezel. While this can achieve an ultra-narrow design, the screws require thickness space, increasing the bezel thickness and making it difficult to achieve an ultra-thin effect. Furthermore, the screw fastening process is complex, increasing production costs.

[0004] In summary, neither of the existing fixing methods can meet the requirements of ultra-thin and ultra-narrow appearance, and both have the problem of high cost. There is an urgent need for a new fixing structure to solve the above technical pain points. Utility Model Content

[0005] This disclosure provides a display bezel self-locking component and display device to solve the technical problems of existing TV bezel fixing methods that cannot simultaneously meet the requirements of ultra-thin and ultra-narrow appearance and have high costs.

[0006] The self-locking display frame component provided in this embodiment includes: a back plate and side frames. The back plate has a protruding structure near the edge on a large surface area. At least three side frames are provided, each side frame being distributed on an adjacent periphery of the back plate. At least one side wall of each side frame has a bending guide path. The bending guide path includes a first guide through hole along the width direction of the side frame and a second guide through hole along the length direction of the side frame. The first guide through hole and the second guide through hole are connected. During assembly, the protruding structure is configured to extend into the bending guide path through the first guide through hole and move to the boundary position along the second guide through hole. The inner wall of the second guide through hole and the protruding structure are fitted with a clearance fit or a transition fit.

[0007] The first guide hole includes a first open end and a first closed end, and the second guide hole includes a second open end and a second closed end. The first closed end is connected to and communicates with the second open end, so that the protruding structure extends into the bent guide path through the first open end and is limited and assembled with the side where the second closed end of the second guide hole is located.

[0008] The first open end and the second closed end have a blocking edge between them to prevent the protruding structure from coming off along the width direction of the side frame.

[0009] The second guide hole has a small limiting protrusion that protrudes inward along the width direction of the side frame near the second closed end. The small limiting protrusions are arranged in pairs, and the two small limiting protrusions form a small limiting channel for the protrusion structure to pass into the second closed end. The outer wall of the protrusion structure and the small limiting channel are configured to be interference fit. The small limiting protrusion has recoverable micro-elastic compression characteristics.

[0010] The two adjacent side frames are configured with a continuous concave-convex positioning structure to form a self-locking limiting structure along their own length direction between the two adjacent side frames.

[0011] The continuous concave-convex positioning structure includes a continuous groove structure and a continuous protrusion structure that is aligned and assembled with the continuous groove structure. The continuous groove structure is formed at one end of one of the side frames, and the continuous protrusion structure is formed at one end of the other side frame.

[0012] The continuous groove structure includes a complete groove on the inner side and a semi-open groove on the outer side, and the continuous protrusion structure includes a complete protrusion on the inner side and a semi-open protrusion on the outer side. The complete protrusion is configured to align with the complete groove, and the semi-open protrusion is configured to align with the semi-open groove.

[0013] The first guide hole and the second guide hole together form an L-shaped through hole structure, and a notch is formed on the short side of the L-shaped through hole structure for the protruding structure to extend into.

[0014] Wherein, along the thickness direction of the side frame, the protruding structure is higher than the plane on the side where the bending guide path is located, so that the boundary of the bending guide path blocks the protruding structure in place.

[0015] This disclosure also provides a display device including the aforementioned display frame self-locking member, and a bottom support frame, the bottom support frame being mounted on the bottom side of the back plate, the bottom support frame having a support plane for supporting the side frames on both sides.

[0016] Compared with the prior art, the technical solutions provided in this disclosure have the following advantages: The display bezel self-locking component and display device provided in this disclosure have a simple and clear assembly path through which the protruding structure extends into the first guide hole and moves to the boundary through the second guide hole. The clearance fit or transition fit between the second guide hole and the protruding structure ensures smooth assembly and prevents loosening of the side bezel after assembly, thus improving stability. It should be noted that the fixation is achieved through the cooperation of the protruding structure of the back plate and the bent guide path of the side bezel, eliminating the need for additional metal springs, thus avoiding the occupation of width space, and eliminating the need for additional screws, thus avoiding the occupation of thickness space. Furthermore, the fixing structure does not intrude into the internal space of the display area, enabling both ultra-thin and ultra-narrow bezel designs for the display device. Compared to the snap-fit ​​spring solution, it saves on the material cost of metal springs; compared to the back-locking screw solution, it saves on the material cost of screws and the cost of complex locking processes. Self-locking fixation is achieved solely through structural optimization of the back plate and side bezel, significantly reducing product manufacturing costs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0024] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0025] refer to Figures 1-6 This disclosure provides a display frame self-locking component, including: a back plate 2 and side frames 1. The back plate 2 has a raised structure near the edge on a large surface area. At least three side frames 1 are provided, each side frame 1 is distributed on an adjacent periphery of the back plate 2, and at least one side wall of each side frame 1 has a bending guide path 11. The bending guide path 11 includes a first guide through hole 111 along the width direction of the side frame 1 and a second guide through hole 112 along the length direction of the side frame 1. The first guide through hole 111 and the second guide through hole 112 are connected. During assembly, the raised structure is configured to extend into the bending guide path 11 through the first guide through hole 111 and move to the boundary position along the second guide through hole 112. The inner wall of the second guide through hole 112 and the raised structure are fitted with a clearance fit or a transition fit.

[0026] For example, the large area of ​​the back panel 2 refers to the main plane area of ​​the back panel 2 with the largest area, which is used to support core components such as display glass and optical components. For example, the flat area of ​​the back panel 2 of an LCD TV is parallel to the screen display surface and covers most of the projection area of ​​the screen, which is different from the non-main plane structure such as the folded edge and step at the edge of the back panel 2.

[0027] For example, the protrusion structure can be any protrusion shape such as hemispherical, cylindrical, or rectangular block. The material of the protrusion structure can be the same as that of the back plate 2, such as an integral stamped protrusion of the metal back plate 2 or an integral injection molded protrusion of the plastic back plate 2.

[0028] For example, taking the side bezel 1 of a TV as an example, the width direction of the side bezel 1 refers to the width direction of the shape on the side parallel to the screen display surface; the length direction of the side bezel 1 refers to the length direction of the shape on the side parallel to the screen display surface.

[0029] For example, according to the functional partition, the bent guide path 11 can be a splicing channel path with two different directional paths, which can be an "L" or "┐" shaped through hole structure. The first guide through hole 111 is opened along the width direction, but does not penetrate the side frame 1 in its own width direction area. The second guide through hole 112 is opened along the length direction, but on the basis of the first guide through hole 111, the direction of the through hole path is further changed. The two are connected at the intersection to form an entrance, guide and positioning channel for the movement of the protruding structure.

[0030] For example, the side frame 1 of this disclosure embodiment may have three parts, which are respectively distributed on the top side, left side and right side of the back plate 2.

[0031] For example, the side frame 1 of this embodiment may also have four, which are respectively distributed on the top, left, right and bottom sides of the back plate 2. The side frame 1 located on the bottom side also supports and locks the side frames 1 on the left and right sides.

[0032] Thus, the assembly path, where the protruding structure extends along the first guide hole 111 and moves to the boundary along the second guide hole 112, is simple and clear. The clearance fit or transition fit between the second guide hole 112 and the protruding structure ensures smooth assembly and prevents the side frame 1 from loosening after assembly, improving stability. It should be noted that the fixation achieved through the cooperation of the protruding structure of the back plate 2 and the bent guide path 11 of the side frame 1 eliminates the need for additional metal springs, avoiding the need for width space and additional screws, thus avoiding the need for thickness space. Furthermore, the fixing structure does not intrude into the internal space of the display area, enabling both ultra-thin and ultra-narrow bezel designs for the display device. Compared to the snap-fit ​​spring solution, it saves on metal spring material costs; compared to the back-locking screw solution, it saves on screw material and complex locking process costs. Self-locking fixation is achieved solely through structural optimization of the back plate 2 and the side frame 1, significantly reducing product manufacturing costs.

[0033] Considering the specific construction schemes of the first guide through hole 111 and the second guide through hole 112, in the self-locking component of the display frame provided in the embodiments of this disclosure, the first guide through hole 111 includes a first open end 1111 and a first closed end 1112, and the second guide through hole 112 includes a second open end 1121 and a second closed end 1122. The first closed end 1112 is connected to and communicates with the second open end 1121, so that the protruding structure extends into the bent guide path 11 through the first open end 1111 and is limited and assembled with the side where the second closed end 1122 of the second guide through hole 112 is located.

[0034] For example, the first opening end 1111 refers to the entrance end of the first guide hole 111 on the wall surface of the side frame 1. This end does not completely penetrate the corresponding side wall of the side frame 1, but only forms a channel for the protruding structure to extend into, which is at least a small notch.

[0035] For example, the first closed end 1112 refers to the end of the first guide hole 111 that is away from the opening. This end does not penetrate the wall of the side frame 1, forming a closed blocking structure to prevent the protruding structure from moving excessively along the width direction of the first guide hole 111.

[0036] For example, the second open end 1121 refers to the port where the second guide through hole 112 connects with the first guide through hole 111. This end is connected to the first closed end 1112 of the first guide through hole 111, forming a transition channel for the protruding structure to turn from the first guide through hole 111 to the second guide through hole 112.

[0037] For example, the second closed end 1122 refers to the end of the second guide through hole 112 that manages the first guide through hole 111. This end also does not penetrate the wall of the side frame 1, forming a limiting structure to limit the movement of the protruding structure along the length direction of the second guide through hole 112.

[0038] For example, the first closed end 1112 is connected to and communicates with the second open end 1121, which means that the closed end wall of the first guide through hole 111 is directly connected to the open end wall of the second guide through hole 112, and the internal channels of the two are connected, which can form a continuous channel similar to an L shape.

[0039] For example, the limiting assembly of the protruding structure with the side where the second closed end 1122 of the second guide through hole 112 is located means that after the protruding structure moves along the second guide through hole 112 to contact the second closed end 1122, the second closed end 1122 will limit the protruding structure along the length direction of the second guide through hole 112. At the same time, the protruding structure and the inner wall of the second guide through hole 112 cooperate to form a limit perpendicular to the length direction, thereby achieving fixation together.

[0040] In this way, the first closed end 1112 restricts the excessive movement of the protruding structure along the width direction, ensuring that the protrusion can be precisely aligned with the entrance of the second guide through hole 112; and the second closed end 1122 restricts the end point of the movement of the protrusion along the length direction, so that the assembly position of each protruding structure is uniform, avoiding problems such as tilting of the side frame 1 and uneven gaps caused by inconsistent assembly strokes, thus improving the consistency of the display device frame assembly and the flatness of the appearance. At the same time, the first closed end 1112 and the second closed end 1122 form a bidirectional limit, preventing the protrusion from detaching along the width direction and limiting the protrusion from moving along the length direction. With the gap or transition fit between the second guide through hole 112 and the protrusion, the connection between the side frame 1 and the back plate 2 forms a double-limited combination and a tight fit, so that even if the device is subjected to vibration or impact during transportation and use, the frame is not easy to shift or loosen.

[0041] In addition, the path consisting of the first open end 1111, the first closed end 1112, the second open end 1121, and the second closed end 1122 is clearly defined, forming a standardized assembly guide. Operators do not need to make additional adjustments or calibrations; they only need to insert the protrusion into the path and move it to the closed end to complete the assembly. Compared with the complex operation of traditional screw fastening, which requires repeated alignment of screw holes and tightening, this reduces assembly steps and improves the assembly efficiency of the production line.

[0042] It should be noted that the closed ends of the first guide through hole 111 and the second guide through hole 112 do not penetrate the wall of the side frame 1. There is no need to reserve additional penetration space or avoidance structure, so that the guide through hole can be set close to the edge of the side frame 1 without occupying the internal space of the display area. It also does not need to occupy additional width or thickness space like metal springs or screws, further ensuring the ultra-thin and ultra-narrow design of the display device frame.

[0043] Further considering the structural features of the bent guide path 11, in the display frame self-locking component provided in this embodiment, there is a blocking edge between the first open end 1111 and the second closed end 1122 to prevent the protruding structure from coming out along the width direction of the side frame 1.

[0044] For example, the blocking edge is a protrusion or step-like structure extending along the inner wall of the bent guide path 11. Its cross-section can be rectangular, arc-shaped, etc., and its height or thickness should be such that it can prevent the protrusion structure from coming out without affecting the assembly.

[0045] For example, the blocking edge is located on the inner wall of the bent guide path 11 between the first open end 1111 and the second closed end 1122. Specifically, it can be set at the junction of the first guide through hole 111 and the second guide through hole 112, or extend along a section of the inner wall of the second guide through hole 112 near the first guide through hole 111.

[0046] In this way, by restricting the displacement of the protruding structure along the width direction of the side frame 1 by blocking the edge, the problem of the protruding structure coming out of the bending guide path 11 is effectively avoided in scenarios such as transportation bumps and daily use collisions. At the same time, the blocking edge can reduce the movement of the protruding structure in the width direction, and avoid the relative position shift of the side frame 1 and the back plate 2 due to the displacement of the protrusion during long-term use. This ensures the overall dimensional accuracy of the display frame, prevents gaps or compression between the frame and the display glass and optical components, and maintains the integrity and flatness of the display image.

[0047] It should be noted that there is no need to add additional anti-detachment components such as buckles and springs. The anti-detachment function can be achieved simply by bending the blocking edge of the inner wall of the guide path 11. Without increasing material costs and assembly processes, the integrated setting of guiding, limiting and anti-detachment is achieved.

[0048] Considering that the bending guide path 11 can provide a limiting scheme to prevent the protruding structure from detaching, in the display frame self-locking component provided in this embodiment, the second guide through hole 112 has a small limiting protrusion that protrudes inward along the width direction of the side frame 1 at a position near the second closed end 1122. The small limiting protrusions are arranged in pairs, and the two small limiting protrusions form a small limiting channel for the protruding structure to pass through to the second closed end 1122. The outer wall of the protruding structure and the small limiting channel are configured to be interference fit. The small limiting protrusion has recoverable micro-elastic compression characteristics.

[0049] For example, the small limiting protrusions can be symmetrically distributed with the central axis of the second guide hole 112 as the axis of symmetry, and usually 1-2 pairs are provided, each pair containing two protrusions located on the inner walls on both sides in the width direction. For example, a pair of small limiting protrusions are provided at a predetermined distance near the second closed end 1122, with the vertices of the two protrusions facing each other to form a symmetrical blocking structure.

[0050] For example, the small limiting channel refers to the gap space between a pair of small limiting protrusions, which is the only path for the protrusion structure to move to the second closed end 1122.

[0051] For example, the maximum outer diameter of the protrusion structure can be greater than the minimum width of the small limiting channel. During assembly, a certain external force needs to be applied to make the small limiting protrusion generate micro-elastic compression, so that the protrusion structure is squeezed into the channel. After assembly, the outer wall of the protrusion structure fits tightly with the inner wall of the channel.

[0052] In this way, the interference fit between the small limiting protrusion and the protrusion structure can form a tight mechanical lock, effectively preventing the protrusion structure from accidentally coming off along the length direction of the second guide through hole 112 or the width direction of the side frame 1. Even if the display device encounters severe vibration, impact or structural stress during long-term use, it can still maintain a stable connection between the side frame 1 and the back plate 2, reducing the risk of equipment failure caused by structural separation.

[0053] It should be noted that there is no need to add additional anti-detachment components such as buckles, springs, and screws. The dual functions of anti-detachment and positioning can be achieved simply by the small limiting protrusion on the inner wall of the second guide hole 112. Under the premise of not increasing material costs and not occupying extra space, the integrated setting of guiding, limiting and anti-detachment can be achieved.

[0054] Considering the limiting assembly scheme between two adjacent side frames 1, in the display frame self-locking component provided in this embodiment, two adjacent side frames 1 are configured to adopt a continuous concave-convex positioning structure so that a self-locking limiting structure along its own length direction is formed between two adjacent side frames 1.

[0055] For example, the continuous concave-convex positioning structure refers to the pairing structure of continuously distributed protrusions extending along the length direction of the frame on the connecting end face of adjacent side frame 1, and corresponding continuous grooves recessed inward along the length direction of the other frame, wherein both the protrusions and the grooves have the same wall thickness as the side frame 1.

[0056] In this way, the continuous concave-convex positioning structure can achieve bidirectional self-locking limit along the length of the side frame 1, effectively preventing the adjacent side frame 1 from shifting along the length direction due to vibration or external impact during transportation and use of the display device, reducing gaps or misalignment at the frame joints; through the continuously distributed concave-convex positioning, the joint positions of adjacent side frame 1 can be precisely aligned, avoiding overall frame deformation caused by missing local positioning, keeping the length and width dimensional errors of the frame within a very small range, ensuring the subsequent assembly compatibility with the display glass and back panel 2, and reducing assembly difficulties caused by dimensional deviations.

[0057] Considering the specific limiting structure scheme between two adjacent side frames 1, in the display frame self-locking component provided in this embodiment, the continuous concave-convex positioning structure includes a continuous groove structure 12 and a continuous protrusion structure 13 that is aligned and assembled with the continuous groove structure 12. The continuous groove structure 12 is formed at one end of one side frame 1, and the continuous protrusion structure 13 is formed at one end of the other side frame 1.

[0058] For example, the different grooves in the continuous groove structure 12 have different groove depths along the length direction of the side frame 1.

[0059] For example, the different protrusions in the continuous protrusion structure 13 have different protrusion heights along the length direction of the side frame 1.

[0060] In this way, the continuous protrusions and continuous grooves fit together along their entire length, avoiding gaps caused by lack of local positioning, and ensuring that the connecting end faces of adjacent side frames 1 fit together completely.

[0061] Considering the specific structural features of the continuous groove structure 12 and the continuous protrusion structure 13, in the self-locking component of the display frame provided in this embodiment, the continuous groove structure 12 includes a complete groove 121 located on the inner side and a semi-open groove 122 located on the outer side, and the continuous protrusion structure 13 includes a complete protrusion 131 located on the inner side and a semi-open protrusion 132 located on the outer side. The complete protrusion 131 is configured to be aligned and assembled with the complete groove 121, and the semi-open protrusion 132 is configured to be aligned and assembled with the semi-open groove 122.

[0062] For example, the complete groove 121 refers to a closed groove located inside the connecting end face of the side frame 1, that is, the side closer to the display area. The groove has complete sidewalls on both sides along the thickness direction of the side frame 1, forming a regular or irregular U-shaped closed structure.

[0063] For example, the semi-open groove 122 refers to a semi-closed groove located on the outer side of the connecting end face of the side frame 1, that is, on the side away from the display area. The groove has no sidewall on one side (usually the outer side) along the thickness direction of the side frame 1, forming a regular or irregular C-shaped open structure.

[0064] For example, the complete protrusion 131 refers to a closed protrusion that is adapted to the size of the complete groove 121. The protrusion has a complete structure on both sides along the thickness direction of the side frame 1, and its cross-section is completely matched with the U-shaped groove of the complete groove 121.

[0065] For example, the semi-open protrusion 132 refers to a semi-closed protrusion that is adapted to the size of the semi-open groove 122. The protrusion has a notch on one side (outer side) along the thickness direction of the side frame 1, and the cross-section matches the C-shaped groove of the semi-open groove 122.

[0066] In this way, the fitting of the complete groove 121 and the complete protrusion 131 can achieve all-round positioning of the adjacent side frame 1 along the thickness direction, avoiding displacement or shaking of the frame on the side near the display area, ensuring the assembly accuracy of the display glass and optical components, and preventing misalignment of the display screen due to frame offset; the adaptation of the semi-open groove 122 and the semi-open protrusion 132 can further enhance the self-locking effect along the length direction without affecting the appearance of the outer side of the frame, while avoiding interference from the outer structure and adapting to the setting requirements of ultra-narrow bezels; the combination of the two types of concave and convex structures makes the connection of adjacent side frame 1 form a double fixation of inner closed positioning and outer open adaptation, which not only improves the stability and deformation resistance of the structural connection, but also takes into account the ease of assembly and appearance integrity, while eliminating the need for additional connectors, effectively controlling costs, and adapting to side frame 1 designs of different thicknesses and widths.

[0067] Considering the specific forming schemes of the first guide through hole 111 and the second guide through hole 112, in the self-locking component of the display frame provided in this embodiment, the first guide through hole 111 and the second guide through hole 112 together form an L-shaped through hole structure, and a notch for the protruding structure to extend into is formed on the short side of the L-shaped through hole structure.

[0068] For example, the L-shaped through hole structure refers to the overall through hole shape resembling the letter "L" formed by the first guide through hole 111 and the second guide through hole 112 being perpendicularly connected to each other. One of the through holes extends along the width direction of the side frame 1, and the other extends along the length direction of the side frame 1. The two are completely connected at their intersection, forming a continuous corner channel.

[0069] For example, the short side refers to the side where the shorter through hole segment is located in the L-shaped through hole structure. Usually, the length of the first guide through hole 111 is less than that of the second guide through hole 112. In this case, the side where the first guide through hole 111 is located is the short side.

[0070] In this way, the L-shaped through-hole structure allows for precise insertion of the protruding structure through the short-side notch, while the long-side through-hole provides guidance and limitation, making the protrusion assembly path clearer, avoiding assembly deviations caused by multiple openings, improving the positioning accuracy of the protrusion and through-hole mating, and ensuring the consistency of the connection between the side frame 1 and the back plate 2. The directional design of the short-side notch restricts the protrusion to only extend from a preset direction, reducing misoperation during assembly. At the same time, the corner transition of the L-shaped structure reduces the risk of jamming when the protrusion moves, improving assembly efficiency. In addition, the L-shaped through-hole structure is compact and does not require additional space inside the frame, making it suitable for ultra-narrow and ultra-thin frame designs. Furthermore, the one-piece molded through-hole structure eliminates the need for additional connectors, enhancing the structural integrity of the through-hole and side frame 1 while controlling costs, improving impact and deformation resistance, and extending the service life of the component.

[0071] Considering that the bending guide path 11 can act as a blocking mechanism for the protruding structure to move into place, in the self-locking component of the display frame provided in this embodiment, along the thickness direction of the side frame 1, the protruding structure is higher than the plane on the side where the bending guide path 11 is located, so that the boundary of the bending guide path 11 blocks the protruding structure from moving into place.

[0072] In this way, the protruding structure designed along the thickness direction of the side frame 1 is higher than the plane of the bending guide path 11. The boundary wall of the bending guide path 11 abuts against the protruding part, achieving precise blocking of the protrusion's assembly. This avoids frame deformation or protrusion damage caused by over-assembly, ensuring the positional accuracy of the connection between the side frame 1 and the back plate 2, and reducing alignment deviations during the assembly of display glass and optical components. At the same time, this design eliminates the need for additional limit blocks, clips, or other components. The height difference between the protrusion and the through hole is sufficient to achieve the positioning detection and blocking functions, simplifying the structural design and reducing material costs. Furthermore, the protruding part does not occupy the core space inside the frame, making it suitable for ultra-thin and ultra-narrow frame appearance requirements. In addition, the physical blocking method makes assembly feedback clearer. Operators can judge whether the protrusion is in place by feel, reducing assembly errors and improving production efficiency.

[0073] This disclosure also provides a display device, including the aforementioned display bezel self-locking component, and a bottom support bezel 3. The bottom support bezel 3 is mounted on the bottom side of the back plate 2, and has a support plane for supporting the side bezels 1 on both sides. This achieves all the effects of the aforementioned display device, which will not be elaborated further here.
