Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a display device and a detachable bezel structure. Background Technology

[0002] A bezel is usually installed on the side of the display device, and the camera unit, speaker unit and other devices can be installed inside the bezel.

[0003] In existing technologies, the back panel and frame are usually molded as a single piece. While this improves production efficiency, it also limits the frame's interchangeability, meaning the housing component consisting of the frame and back panel can only accommodate specific functional components. When faced with the installation requirements of different functional components, this necessitates redesigning and remolding the entire housing component, undoubtedly increasing additional production costs. Utility Model Content

[0004] The purpose of this application is to provide a display device and a detachable bezel structure that allows for the installation of different models of functional components without replacing the outer casing.

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

[0006] The housing component includes a back panel and a first frame, wherein the first frame is disposed at the edge of the back panel;

[0007] A corner piece is provided on the outer shell component and located at the end of the first frame. The corner piece is provided with an extension portion that extends along the length direction of the first frame toward the middle area of ​​the first frame.

[0008] The second frame is detachably mounted on the housing component and extends along the length of the first frame, and its end near the second frame engages with the extension of the corner piece.

[0009] The second frame has a contracted state and an expanded state when the temperature changes. In the contracted state or the expanded state, the two ends of the second frame are located between the opposite sides of the outer shell component.

[0010] The technical solution provided in this application, in this display device, when installing the corner piece and the second frame of the display device, requires that the corner piece be installed at the end position of the first frame, and the second frame be installed on the housing component, and that the area of ​​the second frame near the end be fitted with the extension of the corner piece.

[0011] In this way, when faced with the installation requirements of different models of functional components, the installation requirements of different models of functional components can be met by replacing the second frame. At this time, it is only necessary to match the connection method of different second frames with the outer shell component and to fit the end of the second frame with the extension of the corner piece, so that a single outer shell component can be used, thus eliminating the need to reprocess the outer shell component and reducing production costs.

[0012] Since the end of the second frame is fitted with the extension of the corner piece, there is an overlapping area between the end of the second frame and the extension of the corner piece. Therefore, regardless of whether the second frame is in a contracted or expanded state, the end of the second frame and the extension will always maintain a partial overlap. When the second frame changes size due to thermal expansion and contraction, it can effectively avoid the step difference between the end of the second frame and the extension, ensuring the flatness of the display device's appearance.

[0013] In addition, when the second bezel is in a contracted or expanded state, its two ends are located between the opposite sides of the outer casing component. This ensures that no matter how the second bezel expands or contracts due to temperature changes, it will not extend beyond the boundary of the outer casing component in appearance. This avoids obvious step differences, maintains the flatness and smoothness of the overall appearance of the display device, and significantly improves the aesthetics of the product.

[0014] Optionally, the second frame is fitted onto the outer wall surface of the extension.

[0015] Optionally, the outer wall profile of the extension is adapted to the inner wall profile of the second frame.

[0023] Optionally, the second frame includes a body portion that surrounds a mounting cavity for mounting functional components, and the second frame is engaged with the top surface of the body portion via the bottom surface of the body portion.

[0024] Optionally, the bottom surface of the main body is provided with a snap-fit ​​part, the snap-fit ​​part is provided with a snap-fit ​​groove along a side parallel to the main body, and a baffle is formed below the snap-fit ​​groove in the snap-fit ​​part;

[0025] The top surface is provided with a snap-fit ​​hole, and the inner wall of the snap-fit ​​hole is provided with a snap-fit ​​block that mates with the snap-fit ​​groove;

[0026] When the card slot and the card block are engaged, the baffle is located below the card block, and there is a movable gap between the two ends of the card block and the card slot along the length of the first frame.

[0027] Optionally, the rear side wall of the main body is provided with a skirt;

[0028] The skirt extends toward the outer casing component, and the skirt is provided with mounting holes. The outer casing component is provided with connecting holes corresponding to the mounting holes. The skirt is connected to the outer casing component by fasteners passing through the mounting holes and the connecting holes.

[0029] Optionally, the mounting holes include a plurality of spaced first mounting holes, the connecting holes include a plurality of first connecting holes, the plurality of first connecting holes are configured one-to-one with the plurality of first mounting holes, the skirt is connected to the outer shell component by fasteners passing through the first mounting holes and the first connecting holes, and a displacement gap is left between the inner wall surface of the first mounting holes and the outer wall surface of the fasteners.

[0030] Optionally, the mounting hole further includes a second mounting hole, which is located in the middle area of ​​the skirt. The connecting hole further includes a second connecting hole, which is corresponding to the first connecting hole. The skirt is connected to the housing component through the fastener passing through the second mounting hole and the second connecting hole, and the inner wall surface of the second mounting hole abuts against the outer wall surface of the fastener.

[0031] Optionally, the fastener includes a first connecting segment, a second connecting segment, and a third connecting segment coaxially connected in sequence. The diameter of the first connecting segment is larger than the diameter of the second connecting segment, so that a first step surface is formed between the first connecting segment and the second connecting segment. The diameter of the second connecting segment is larger than the diameter of the third connecting segment, so that a second step surface is formed between the second connecting segment and the third connecting segment.

[0040] The technical solution provided in this application, this detachable frame structure, taking the installation of the detachable frame structure on a display device as an example, requires the corner piece to be installed at the end position of the first frame, while the second frame is installed on the housing component, and the area of ​​the second frame near the end is sleeved with the extension of the corner piece.

[0041] In this way, when faced with the installation requirements of different models of functional components, the installation requirements of different models of functional components can be met by replacing the second frame. At this time, it is only necessary to match the connection method of different second frames with the outer shell component and to fit the end of the second frame with the extension of the corner piece, so that a single outer shell component can be used, thus eliminating the need to reprocess the outer shell component and reducing production costs.

[0063] In related display device designs, the housing typically consists of a back panel and four bezels surrounding its edges. The top bezel, in particular, is often specially machined to create the holes and support structures required for mounting functional components such as cameras and speakers. This design allows for customization to accommodate different functional components by replacing specific bezels.

[0064] However, to simplify the assembly process and reduce manufacturing costs, some technologies employ a manufacturing method that integrates the back panel and frame. While this design improves production efficiency, it also introduces the limitation that the frame cannot be replaced, meaning the housing components can only be adapted to specific models of functional parts. When faced with the installation requirements of different models of functional parts, this necessitates a complete redesign and mold creation of the entire housing component, undoubtedly increasing additional production costs.

[0065] To address the aforementioned issues, the inventors of this application attempted to perform secondary processing on the frame after it was integrally formed with the back panel to create the holes and support structures for the corresponding functional components. However, the outer casing components are highly susceptible to deformation and damage from impacts during this secondary processing, significantly reducing the yield rate and consequently affecting production costs.

[0066] Based on this, the inventors of this application have redesigned the display device. When faced with the installation requirements of different models of functional components, the installation requirements of different models of functional components can be met by replacing the second frame. At this time, it is only necessary to match the connection method of different second frames with the outer shell component and to fit the end of the second frame with the extension of the corner piece. Then, a single outer shell component can be used, so that the outer shell component does not need to be reprocessed, thereby reducing production costs.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0068] The following is combined with Figures 1 to 15 The following describes embodiments of the present invention.

[0069] According to embodiments of the present invention, on the one hand, such as Figures 1 to 15 As shown, a display device is provided, which can be a device with display function and integrated button function, such as an interactive flat panel, smart screen, smart chatbot, or smart blackboard. The display device includes a housing component 100, a corner piece 200, and a second frame 300.

[0070] Specifically, such as Figure 1 and Figure 2 As shown, the housing component 100 includes a back panel 120 and a first frame 110. The first frame 110 is mounted on the edge of the back panel 120.

[0071] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 15 As shown, the corner piece 200 is mounted on the housing component 100, and the corner piece 200 is disposed at the end of the first frame 110. The corner piece 200 is provided with an extension 210, which extends from the end of the first frame 110 toward the middle region of the first frame 110 along the length direction of the first frame 110.

[0072] Specifically, such as Figures 1 to 4 As shown, the second frame 300 is detachably mounted on the housing component 100, and the second frame 300 extends along the length direction of the first frame 110. The end near the second frame 300 engages with the extension 210 of the corner piece 200.

[0073] Specifically, such as Figures 1 to 5As shown, the second frame 300 exists in a contracted state and an expanded state when the temperature changes. In the contracted or expanded state, the two ends of the second frame 300 are located between the opposite sides of the outer shell component 100.

[0074] When installing the corner piece 200 and the second frame 300 of this display device, the corner piece 200 needs to be installed at the end position of the first frame 110, and the second frame 300 needs to be installed on the housing component 100, and the area of ​​the second frame 300 near the end needs to be sleeved with the extension 210 of the corner piece 200.

[0075] In this way, when faced with the installation requirements of different models of functional components, the installation requirements of different models of functional components can be met by replacing the second frame 300. At this time, it is only necessary to match the connection method of different second frames 300 with the outer shell component 100 and fit the end of the second frame 300 with the extension 210 of the corner piece 200, so that a single outer shell component 100 can be used, thus eliminating the need for reprocessing the outer shell component 100 and reducing production costs. Especially for the one-piece molding of the outer shell component 100, the overall mold opening cost of the outer shell component 100 is expensive. If the outer shell component 100 is molded separately for different models of functional components, it will result in a great waste of costs. Among them, functional components can be cameras, speakers, light sensors, and proximity sensors, etc.

[0076] Since the end of the second frame 300 is sleeved with the extension 210 of the corner piece 200, there is an overlap area 310 between the end of the second frame 300 and the extension 210 of the corner piece 200. Therefore, regardless of whether the second frame 300 is in a contracted or expanded state, the end of the second frame 300 and the extension 210 will always maintain a partial overlap. When the second frame 300 changes size due to thermal expansion and contraction, it can effectively avoid the step difference between the end of the second frame 300 and the extension 210, thus ensuring the flatness of the appearance of the display device.

[0077] In addition, when the second bezel 300 is in a contracted or expanded state, its two ends are located between the opposite sides of the housing component 100, ensuring that no matter how the second bezel 300 expands or contracts due to temperature changes, it will not extend beyond the boundary of the housing component 100 from the appearance, avoiding obvious step differences, maintaining the flatness and smoothness of the overall appearance of the display device, and significantly improving the aesthetics of the product.

[0078] Specifically, the corner piece 200 can be made of metal or plastic to prevent it from expanding or contracting due to thermal expansion and contraction. In this embodiment, no specific restrictions are placed on the material of the corner piece 200.

[0079] Specifically, when the corner piece 200 is disposed at the end of the first frame 110, the corner piece 200 may be flush with the side of the outer shell component 100, may partially protrude from the side of the outer shell component 100, or may be recessed inward into the side of the outer shell component 100. In this embodiment, the position of the corner piece 200 relative to the side of the outer shell component 100 is not specifically limited.

[0080] It should be noted that the end near the second frame 300 is sleeved with the extension 210 of the corner piece 200. This means that the installation position of the end of the second frame 300 is flexible; it can be placed on or inside the extension 210. In this embodiment, the specific fit between the second frame 300 and the corner piece 200 is not limited.

[0081] For example, the end near the second frame 300 can be fitted onto the outer surface of the extension 210. Alternatively, the extension 210 can be hollowed out, allowing the end near the second frame 300 to pass through the interior of the extension 210.

[0082] Specifically, the back panel 120 and the first frame 110 can be designed separately and then connected to each other, or the back panel 120 and the first frame 110 can be integrally formed. In this embodiment, no specific restrictions are imposed on the back panel 120 and the first frame 110.

[0083] Specifically, such as Figure 1 and Figure 2 As shown, other borders can also be provided around the edge of the back panel 120. The first border 110 and other borders can be provided around the edge of the back panel 120. For example, the first border 110 can be provided at the top of the back panel 120, and the other borders can be provided on the left and right sides of the back panel 120.

[0084] Specifically, in the contracted or expanded state, the two ends of the second frame 300 are located between the opposite sides of the outer shell component 100. This can be understood as the ends of the second frame 300 not extending beyond the boundary of the outer shell component 100 in the contracted or expanded state.

[0085] Specifically, the first frame 110 can be a top frame, so that the second frame 300 located on the outer surface of the first frame 110 can have sufficient height to better meet the usage needs of functional components installed within the second frame 300. For example, when the functional component is a camera, the height provided by the second frame 300 allows the camera to have a wider field of view. This means that the camera can capture a larger scene and provide more comprehensive video coverage.

[0086] In one embodiment, such as Figure 3 and Figure 4As shown, the second frame 300 is fitted onto the outer wall surface of the extension 210.

[0087] Mounting the second bezel 300 onto the outer wall of the extension 210 enhances its stability through the structure of the extension 210. The extension 210 provides reliable support for the second bezel 300, strengthening the overall structural integrity of the display device. Furthermore, placing the second bezel 300 on the outer wall of the extension 210 creates a smoother, more unified appearance for the display device. Compared to a separate, protruding second bezel 300, mounting it on the outer wall of the extension 210 reduces its abruptness, improves the overall aesthetics of the product, makes the display device more in line with modern aesthetic demands, and enhances its market competitiveness.

[0088] Furthermore, in terms of equipment maintenance and repair, the second frame 300 is located on the outer wall of the extension 210, making it easier to operate. When the second frame 300 malfunctions, maintenance personnel can directly access it and perform inspection, repair, or replacement without removing too many other parts, thus shortening maintenance time, improving equipment maintenance efficiency, and reducing maintenance costs.

[0089] Specifically, the end of the second frame 300 can be directly fitted onto the outer wall surface of the extension 210, or the end of the second frame 300 can be covered onto the outer wall surface of the extension 210. In this embodiment, the arrangement of the second frame 300 and the extension 210 is not specifically limited.

[0090] In one embodiment, such as Figure 4 As shown, the outer wall profile of the extension 210 is adapted to the inner wall profile of the second frame 300.

[0091] When the outer wall contour of the extension 210 matches the inner wall contour of the second frame 300, the second frame 300 can fit tightly against the outer wall of the extension 210, reducing the gap between the inner wall of the second frame 300 and the outer wall of the extension 210, making the combination of the second frame 300 and the extension 210 more natural and smooth. Visually, the two seem to be a whole, greatly enhancing the aesthetic appearance of the display device.

[0092] The fitted contour can improve the sealing of the joint between the extension 210 and the second frame 300, effectively reducing the possibility of external dust, moisture and other impurities entering the display device.

[0093] For example, taking an outdoor display device as an example, the second frame 300 is adapted to the contour of the extension 210, and with the help of auxiliary sealing measures such as sealing strips, a good sealing structure can be formed to prevent rainwater, sand and dust from corroding the internal components of the device, thereby improving the protection level and service life of the device.

[0094] In one embodiment, such as Figure 1 As shown, the second border 300 is a plastic border.

[0095] The second frame 300 is made of plastic. Plastic raw materials are cheaper than metal, reducing the production cost of the second frame 300. Additionally, plastic has a low density, making it lighter for the same volume, effectively reducing logistics costs during product transportation. Furthermore, the plastic frame is primarily manufactured using injection molding, a simple process that allows for large-scale, rapid production.

[0096] In one embodiment, such as Figure 6 As shown, the first frame 110 has a top surface 111, wherein the top surface 111 is located at the top of the first frame 110, and the second frame 300 is at least partially supported on the top surface 111.

[0097] The top surface 111 of the first frame 110 provides reliable support for the second frame 300, making its installation more stable. Since part of the weight of the second frame 300 is borne by the top surface 111, the gravitational and tensile forces on its connection point with the extension 210 are reduced, lowering the risk of loosening or damage to the connection point 230 due to long-term stress. The support from the top surface 111 of the first frame 110 effectively prevents the second frame 300 from detaching from the extension 210 due to its own weight, ensuring stable operation of the display device during prolonged use.

[0098] When installing the second bezel 300, installers can first place it on the top surface 111 for initial positioning, and then connect and fix it to the extension 210, reducing installation difficulty and improving installation efficiency. When maintaining or replacing the second bezel 300, the support provided by the top surface 111 can be used to more easily disassemble or adjust it, reducing the impact on other components of the display device and lowering maintenance costs and time.

[0099] In one embodiment, such as Figure 4 and Figure 5 As shown, along the length of the first frame 110, the end of the top surface 111 is provided with a relief groove 1113, which is used to avoid the corner piece 200.

[0100] When the corner piece 200 is installed at the end of the first frame 110, since the end of the top surface 111 of the first frame 110 is provided with a relief groove 1113, the relief groove 1113 provides installation space for the corner piece 200, so as to facilitate the installation of the corner piece 200 and avoid misalignment or skewness caused by space interference during assembly.

[0101] In one embodiment, such as Figure 2As shown, the back panel 120 and the first frame 110 are integrally formed.

[0102] Since the back panel 120 and the first frame 110 are integrally formed, the process of processing the back panel 120 and the first frame 110 separately and then assembling them is omitted, which reduces the production cost and assembly cost of the back panel 120 and the first frame 110.

[0103] In one embodiment, such as Figures 1 to 5 As shown, the second frame 300 has a deformation length along the length direction of the first frame 110. The deformation length is the amount of displacement by which the second frame 300, when it is fitted onto one end of the extension 210, contracts or expands towards the extension 210. The length of the extension 210 is greater than the deformation length.

[0104] Since the length of the extension 210 is greater than the deformation length of the second frame 300, when the second frame 300 shrinks or expands, the end of the second frame 300 is engaged with the extension 210 of the corner piece 200 to prevent the second frame 300 from shrinking too much and causing a gap between the second frame 300 and the extension 210.

[0105] Specifically, the deformation length can be understood as the displacement range of the second frame 300 when it is attached to one end of the extension 210 and undergoes elastic deformation.

[0106] In one embodiment, such as Figure 6 , Figure 8 and Figure 9 As shown, the second frame 300 includes a body portion 320, which surrounds a mounting cavity 321 for mounting functional components, such as a camera unit or a speaker unit. The second frame 300 is engaged with the top surface 111 of the body portion 320.

[0107] The snap-fit ​​design allows the second frame 300 to be quickly positioned and engaged with the top surface 111 of the first frame 110 during installation. Installers simply align the snap-fit ​​structure on the bottom of the main body 320 with the corresponding position on the top surface 111, and gently press or push to complete the installation. No additional tools or complicated procedures are required, thus improving installation efficiency.

[0108] In one embodiment, such as Figures 8 to 14As shown, the bottom surface of the main body 320 is provided with a snap-fit ​​portion 322, wherein the snap-fit ​​portion 322 is provided with a snap-fit ​​groove 3221, which is provided along a side parallel to the main body 320. A baffle 3222 is provided on the snap-fit ​​portion 322, located below the snap-fit ​​groove 3221. Furthermore, a snap-fit ​​hole 1111 is provided on the top surface 111, and the inner wall of the snap-fit ​​hole 1111 is provided with a snap-fit ​​block 1112 that mates with the snap-fit ​​groove 3221. When the snap-fit ​​groove 3221 and the snap-fit ​​block 1112 are engaged, the baffle 3222 is located below the snap-fit ​​block 1112, and along the length of the first frame 110, a movable gap 3223 is left between the snap-fit ​​block 1112 and both ends of the snap-fit ​​groove 3221.

[0109] When installing the second frame 300, simply align the snap-fit ​​part 322 with the snap-fit ​​hole 1111 so that the snap-fit ​​block 1112 can fall into the snap-fit ​​groove 3221 to complete the initial snap-fit ​​positioning. No complicated operations or additional tools are required, improving installation efficiency. After the snap-fit ​​groove 3221 and the snap-fit ​​block 1112 are engaged, the baffle 3222 is located below the snap-fit ​​block 1112, forming a limiting structure that effectively prevents the snap-fit ​​block 1112 from coming out of the snap-fit ​​groove 3221. This ensures that the second frame 300 will not easily detach from the first frame 110 due to external force during normal use, enhancing the stability of the connection.

[0110] When the locking slot 3221 and the locking block 1112 are engaged, there is a movable gap 3223 between the two ends of the locking block 1112 and the locking slot 3221. The movable gap 3223 can play a role in buffering and adjustment. When the second frame 300 expands and contracts with heat, the movable gap 3223 can provide a certain deformation space for the second frame 300, avoiding the local arching deformation of the second frame 300 due to stress concentration, thereby further improving the reliability of the connection.

[0111] This can be understood as the second frame 300 typically expanding and contracting due to changes in ambient temperature. When the temperature rises, the second frame 300 expands, and the locking block 1112 tends to press against both ends of the locking groove 3221; when the temperature drops, the second frame 300 contracts, and a gap may appear between the locking block 1112 and the locking groove 3221. The movable gap 3223 provides a buffer space for this thermal expansion and contraction, preventing the second frame 300 from experiencing localized bulging, deformation, or even damage due to concentrated thermal stress. This protects the structural integrity of both the second frame 300 and the first frame 110, and improves the reliability of the entire connection structure under different ambient temperatures.

[0112] Specifically, the snap-fit ​​groove 3221 can be a rectangular groove, a trapezoidal groove, a square groove, etc. In this embodiment, the shape of the snap-fit ​​groove 3221 is not specifically limited.

[0113] Specifically, the size of the movable spacing 3223 can be set according to factors such as the material properties of the second frame 300, the usage environment, and the expected degree of thermal expansion and contraction. In this embodiment, the size and shape of the movable spacing 3223 are not specifically limited.

[0114] In practical applications, the main body 320 may have multiple snap-fit ​​portions 322, which are spaced apart along the length of the main body 320. Correspondingly, the top surface 111 may also have multiple snap-fit ​​holes 1111, which are arranged corresponding to the multiple snap-fit ​​portions 322, so that the multiple snap-fit ​​portions 322 respectively snap into the multiple snap-fit ​​holes 1111, thereby improving connection stability.

[0115] In one embodiment, such as Figure 6 and Figure 7 As shown, the rear side wall of the main body 320 is provided with a skirt 323, which extends toward the outer shell component 100. The skirt 323 has a mounting hole 3231, and the outer shell component 100 has a connecting hole 150. The connecting hole 150 corresponds to the mounting hole 3231, and the skirt 323 is connected to the outer shell component 100 by fasteners 400 passing through the mounting hole 3231 and the connecting hole 150.

[0116] By providing a skirt 323 on the rear side wall of the main body 320 and connecting the second frame 300 to the housing component 100 with a fastener 400 passing through the mounting hole 3231 on the skirt 323, a stable connection can be achieved between the second frame 300 and the housing component 100 at multiple points, increasing the reliability of the connection and reducing the possibility of the second frame 300 shaking or shifting during use.

[0117] The skirt 323 extends toward the housing component 100 and connects with the housing component 100. It can fill the gap between the second frame 300 and the housing component 100 to a certain extent, thus playing a sealing role. This helps to prevent dust, moisture and other impurities from entering the display device, protect the internal functional components of the display device from the influence of the external environment, improve the dustproof and waterproof performance of the device, and extend the service life of the device.

[0118] Mounting holes 3231 are provided on the skirt 323, corresponding to the connecting holes 150 on the housing component 100, making the installation process more convenient. Installers can accurately align the fasteners 400 with the mounting holes 3231 and connecting holes 150 for installation, improving installation efficiency. Furthermore, when it is necessary to disassemble the second frame 300, only the fasteners 400 need to be removed to easily remove the second frame 300 from the housing component 100, facilitating equipment maintenance and repair.

[0119] Specifically, one or more mounting holes 3231 may be provided. In this embodiment, the number of mounting holes 3231 is not specifically limited.

[0120] Similarly, the mounting hole 3231 can be any shape, such as a circular hole, an oblong hole, or a square hole. In this embodiment, the shape of the mounting hole 3231 is not specifically limited.

[0121] In one embodiment, such as Figures 6 to 13 As shown, the mounting hole 3231 includes a plurality of first mounting holes 32311, which are spaced apart. The connecting hole 150 includes a plurality of first connecting holes 151, which are arranged one-to-one with the plurality of first mounting holes 32311. The skirt 323 is connected to the housing component 100 by fasteners 400 passing through the first mounting holes 32311 and the first connecting holes 151, and a displacement gap (not shown in the figure) is left between the inner wall surface of the first mounting hole 32311 and the outer wall surface of the fastener 400.

[0122] When the fastener 400 is installed in the first mounting hole 32311 and the first connecting hole 151, there is a displacement gap between the inner wall of the first mounting hole 32311 and the outer wall of the fastener 400. When the second frame 300 expands and contracts with heat, the displacement gap can provide a certain deformation space for the second frame 300, and avoid the second frame 300 from local arching deformation due to stress concentration.

[0123] Specifically, such as Figure 13 As shown, the cross-section of the first mounting hole 32311 can be set as an oblong hole, and the cross-section of the fastener 400 mating with the first mounting hole 32311 can be set as a circular hole, and the area of ​​the oblong hole is larger than the area of ​​the circular hole, so that a displacement gap is formed between the first mounting hole 32311 and the fastener 400.

[0124] In one embodiment, such as Figures 6 to 14 As shown, the mounting hole 3231 also includes a second mounting hole 32312, which is located in the middle area of ​​the skirt 323. The connecting hole 150 also includes a second connecting hole 152, which is correspondingly provided with the first connecting hole 151. The skirt 323 is connected to the outer shell component 100 through the second mounting hole 32312 and the second connecting hole 152 via fasteners 400, and the inner wall surface of the second mounting hole 32312 abuts against the outer wall surface of the fastener 400.

[0125] A second mounting hole 32312 and a corresponding second connecting hole 152 are provided in the middle area of ​​the skirt 323, and the inner wall surface of the second mounting hole 32312 abuts against the outer wall surface of the fastener 400. This provides a stable connection point in the middle of the skirt 323, which can better limit the displacement of the second frame 300 and enhance the stability of the connection between the second frame 300 and the housing component 100.

[0126] Specifically, such as Figure 14 As shown, the cross-section of the second mounting hole 32312 can be a circular hole, and the cross-section of the fastener 400 mating with the second mounting hole 32312 can be set as a circular hole, and the areas of the two circular holes are matched so that after the fastener 400 passes through the second mounting hole 32312, the inner wall surface of the second mounting hole 32312 abuts against the outer wall surface of the fastener 400.

[0127] In one embodiment, such as Figure 6 and Figure 7 As shown, the fastener 400 includes a first connecting segment 410, a second connecting segment 420, and a third connecting segment 430, which are coaxially arranged sequentially. The diameter of the first connecting segment 410 is larger than the diameter of the second connecting segment 420, forming a first stepped surface 440 between the two segments. The diameter of the second connecting segment 420 is larger than the diameter of the third connecting segment 430, forming a second stepped surface 450 between the two segments. With the skirt 323 mounted on the housing component 100 via the fastener 400, the third connecting segment 430 is connected to the connecting hole 150, the second stepped surface 450 abuts against the housing component 100, the mounting hole 3231 is fitted onto the outer wall of the second connecting segment 420, and a clearance cavity 460 is left between the skirt 323 and the first stepped surface 440.

[0128] The stepped surfaces formed by the different diameters of the first connecting segment 410, the second connecting segment 420, and the third connecting segment 430, when using fasteners 400 to install the second frame 300 onto the housing component 100, are formed by inserting the fasteners 400 into the mounting holes 3231 of the second frame 300, and connecting the third connecting segment 430 into the connecting hole 150, so that the second stepped surface 450 abuts against the housing component 100, ensuring that the fasteners 400 are securely installed on the housing component 100. At this time, the mounting hole 3231 is fitted onto the outer wall surface of the second connecting segment 420, and the skirt 323 is limited by the larger diameter of the first connecting segment 410, making the connection between the second frame 300 and the housing component 100 reliable.

[0129] Meanwhile, the second stepped surface 450 abuts against the outer casing component 100, effectively preventing the fastener 400 from excessively penetrating the connecting hole 150 and ensuring the stability of the connection. The clearance cavity 460 between the skirt 323 and the first stepped surface 440 provides buffer space for the skirt 323 to deform under external force or due to thermal expansion and contraction, preventing the skirt 323 from generating additional stress due to deformation and lack of expansion space. This reduces the risk of deformation, cracking, and other damage to the skirt 323, protects the integrity of the connection structure, and extends the service life of the equipment.

[0130] In one embodiment, combined Figure 4 and Figure 15 As shown, the corner piece 200 also includes an end plate 220, which is located at the end of the extension 210 away from the second frame 300 and protrudes from the outer wall surface of the extension 210.

[0131] The end plate 220 protrudes from the outer wall of the extension 210, effectively dispersing and buffering external forces. When the display device is subjected to collision or pressure, the end plate 220 preferentially absorbs the external impact force, preventing the impact force from acting directly on the connection between the extension 210 and the first frame 110, thereby preventing the connection from cracking or loosening due to excessive force and enhancing the overall stability of the corner piece 200. In addition, the end plate 220 increases the surface area of ​​the corner piece 200, increasing the contact area between the corner piece 200 and other components (such as the housing component 100), further improving the connection strength of the structure.

[0132] Specifically, the top surface of the end plate 220 can be set on the same plane as the top surface of the second frame 300, thereby improving the aesthetic appearance of the display device.

[0133] In one embodiment, such as Figures 1 to 4 As shown, with the corner piece 200 mounted on the housing component 100, the end plate 220 and the side wall surface of the housing component 100 are located on the same plane.

[0134] The end plate 220 is flush with the side wall of the outer casing 100, making the overall appearance of the device smoother and more streamlined, without any protruding parts, thus improving the overall aesthetics of the product. The absence of protruding or recessed parts also makes the display device's surface flat, which is beneficial for packaging, allowing for better adhesion to packaging materials, reducing the amount of packaging material used and packaging space, and lowering packaging costs.

[0135] In one embodiment, combined Figure 1 and Figure 15 As shown, the corner piece 200 also includes a connecting part 230, and the corner piece 200 is detachably mounted on the back plate 120 via the connecting part 230.

[0136] During the assembly of the display device, since the corner piece 200 is provided with a connecting part 230, the installer can easily install the corner piece 200 onto the back plate 120 without complicated tools or processes, and can also easily and quickly remove the corner piece 200 from the back plate 120, thus improving the efficiency of installation and maintenance.

[0137] Specifically, the connecting part 230 may be an assembly hole, a slot structure, a magnetic structure, etc. In this embodiment, the structure of the connecting part 230 is not specifically limited.

[0138] In one embodiment, such as Figure 1 As shown, there are two corner pieces 200, which are respectively located at both ends of the first frame 110.

[0139] From an appearance perspective, the two corner pieces 200 are set at both ends of the first frame 110, which can make the overall appearance of the display device more beautiful and neat, and improve the visual effect of the product.

[0140] According to an embodiment of the present invention, on the other hand, as... Figures 1 to 15 As shown, a detachable frame structure is also provided, including a corner piece 200 and a second frame 300.

[0141] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 15 As shown, the corner piece 200 has an extension 210 that extends along the length of the corner piece 200. It should be noted that, as... Figure 3 As shown, the length direction of the corner piece 200 is consistent with the length direction of the first frame 110.

[0142] Specifically, such as Figures 1 to 4 As shown, the second frame 300 mates with the corner piece 200, and the end near the second frame 300 is sleeved with the extension 210 of the corner piece 200.

[0143] To install this detachable bezel structure on a display device, for example, the corner piece 200 needs to be installed at the end of the first bezel 110, while the second bezel 300 is installed on the housing component 100, and the area of ​​the second bezel 300 near the end is fitted with the extension 210 of the corner piece 200.

[0144] In this way, when faced with the installation requirements of different models of functional components, the installation requirements of different models of functional components can be met by replacing the second frame 300. At this time, it is only necessary to match the connection method of different second frames 300 with the outer shell component 100 and to fit the end of the second frame 300 with the extension 210 of the corner piece 200. Then, a single outer shell component 100 can be used, thus eliminating the need to reprocess the outer shell component 100 and reducing production costs.
