Description

Technical Field

[0001] This application relates to the field of display devices, and in particular to an interactive flat panel and an external module. Background Technology

[0002] To simplify the assembly process and reduce manufacturing costs, the technology employs a manufacturing method that integrates the back panel and frame.

[0003] While this design improves production efficiency, it also imposes a limitation on the frame, meaning the outer casing, consisting of the frame and back panel, can only be fitted to specific functional components. When faced with installation requirements for different functional components, this necessitates a complete redesign and mold creation of the entire outer casing, undoubtedly increasing production costs. Summary of the Invention

[0004] The purpose of this application is to provide an interactive flat panel and an external module that can accommodate the installation of different models of functional components without replacing the outer casing.

[0005] To achieve the above objectives, this application provides an interactive flat panel, which includes at least a housing component and an external module. The housing component includes a back panel and a first frame, with the first frame disposed at the edge of the back panel. The external module has a mounting cavity for mounting functional components. The external module is located on the outer surface of the first frame and is detachably connected to the housing component. The external module extends along the length direction of the first frame, and both ends of the external module are adjacent to the two ends of the first frame.

[0006] The technical solution provided in this application separates the installation requirements of functional components from the first frame by mounting the functional components onto an external module and detachably connecting the external module to the first frame. This allows for the installation of different models of functional components by simply replacing the external module. Only the connection method between the different external modules and the outer shell component needs to be matched, allowing them to share a single outer shell component without requiring reprocessing, thus reducing production costs. Especially for a one-piece molded outer shell component, the overall mold cost is high; creating separate molds for different models of functional components would result in significant cost waste.

[0007] Optionally, the first border is the top border.

[0008] With the above solution, the external module located on the outer surface of the first frame can have sufficient height to meet the better usage requirements of the functional components installed in the external module.

[0009] Optionally, the first frame has an outer segment; the outer segment is located at the top of the first frame, and the external module is at least partially supported on the outer segment.

[0010] With the above solution, the first frame can support the external module through its outer section, so that the connection between the external module and the outer shell does not need to bear the overall force of the external module, thus avoiding the risk of the external module accidentally falling off due to excessive weight. At the same time, it reduces the strength requirements of the connection between the external module and the outer shell, simplifying the installation process.

[0011] Optionally, the external module includes a body portion; the body portion surrounds and forms the mounting cavity, and the external module is engaged with the outer side segment through the bottom surface of the body portion.

[0012] With the above solution, when the main body is installed on the outer section by snap-fit, the connection between the main body and the outer section is covered by the main body, thereby achieving a hidden connection and improving aesthetics.

[0013] Optionally, the back panel and the first frame are integrally formed.

[0014] With the above solution, the back panel and the first frame do not require additional assembly, simplifying the production process. Furthermore, the splicing gap between the back panel and the first frame can be optimized to improve the aesthetics of the interactive flat panel.

[0015] Optionally, the front end of the back panel is formed with a first planar segment, and the outer segment extends forward from the upper side of the first planar segment; the first frame also has a front segment, which extends downward from the end of the outer segment away from the first planar segment in a direction perpendicular to the outer segment.

[0016] Optionally, the front side of the body portion is substantially flush with the front side of the front side segment.

[0017] The above solution ensures a relatively flat viewing side for the interactive flat panel, reducing gaps or steps in the surface and maintaining its aesthetic appeal. Simultaneously, it avoids the problem of the main body protruding beyond the front side of the front section, which could create shadows within the display area under external light, negatively impacting the user experience.

[0018] Optionally, the rear side of the main body is provided with a skirt; the skirt extends toward the outer shell component and fits against the rear side of the first planar segment.

[0019] Using the above method, the external module can be installed by referring to the fit between the skirt and the rear side of the first plane segment, which can quickly position and install the external module and reduce the possibility of misalignment during installation.

[0020] Optionally, the skirt is connected to the first planar segment by fasteners; or, the bottom surface of the skirt is provided with a lug, which is connected to the first planar segment by fasteners.

[0021] With the above solution, the fasteners are located on the back of the interactive panel, that is, on the side that is not frequently seen, or in other words, on the side that is not visible when the interactive panel is in normal use, thereby avoiding the connection point being exposed and improving the aesthetics.

[0022] Optionally, the bottom surface of the main body is provided with a snap-fit ​​portion, the snap-fit ​​portion 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; the outer segment is provided with a first snap-fit ​​hole, the first snap-fit ​​hole has an insertion area and a snap-fit ​​area arranged along the length direction of the outer segment, and the inner side of the first snap-fit ​​hole located at the snap-fit ​​area is provided with a locking block that mates with the snap-fit ​​groove; when the snap-fit ​​portion is inserted into the insertion area, the main body moves toward the snap-fit ​​area, the locking block forces the end of the snap-fit ​​portion adjacent to the snap-fit ​​groove to move away from the locking block, so that the locking block is inserted into the snap-fit ​​groove, and the baffle moves below the locking block.

[0023] With the above solution, when the external module attempts to detach from the outer casing, the top surface of the locking block and the bottom surface of the baffle are in contact with each other. In other words, the force-bearing surface between the external module and the outer casing is the contact surface between the main body and the outer segment. This increases the contact area between the main body and the outer segment, improves the upper limit of the destructive force that can be withstood, and avoids the situation where the external module detaches from the outer casing due to accidental force.

[0024] Optionally, the bottom surface of the main body is provided with a second snap-fit ​​hole; one end of the snap-fit ​​part away from the snap-fit ​​groove is connected to the inner side of the second snap-fit ​​hole, and the snap-fit ​​part protrudes from the bottom surface of the main body, and the height of the snap-fit ​​groove below the bottom surface of the main body is not less than the thickness of the snap block.

[0025] Through the above solution, the snap-fit ​​part can also extend into the second snap-fit ​​hole, thereby increasing the thickness of the snap-fit ​​part, reducing the possibility of breakage due to elastic deformation of the snap-fit ​​part, and improving the service life of the snap-fit ​​part.

[0026] Optionally, the external module is composed of at least two splicing segments, and the splicing surface of two adjacent splicing segments is approximately perpendicular to the length direction of the external module.

[0027] With the above solution, the external module is made up of multiple short splicing segments manufactured separately and then spliced ​​together. This makes each splicing segment easy to process and transport materials, thus reducing production costs.

[0028] Optionally, the external module is composed of three splicing segments, namely a first splicing segment, a second splicing segment, and a third splicing segment; the second splicing segment is located between the first splicing segment and the third splicing segment, and the ends of the first splicing segment and the third splicing segment away from the second splicing segment are provided with downwardly inclined transition surfaces.

[0029] The above solution uses transition surfaces to connect the two ends of the external module to the two sides of the interactive flat panel, thereby improving the aesthetics of the interactive flat panel.

[0030] Optionally, the external module is manufactured by injection molding; the housing component further includes a second frame and a third frame, the second frame and the third frame being side frames.

[0031] To achieve the above objectives, this application also provides an external module, which includes a body and a snap-fit ​​portion located on the bottom surface of the body. The body surrounds a mounting cavity for mounting functional components, and the bottom surface of the body has a second snap-fit ​​hole. The snap-fit ​​portion is located within the second snap-fit ​​hole and partially protrudes from the bottom surface of the body. One end of the snap-fit ​​portion is connected to the inner side of the second snap-fit ​​hole. The snap-fit ​​portion has a snap-fit ​​groove with an opening facing the side of the snap-fit ​​portion, and a baffle is formed below the snap-fit ​​groove. At least a portion of the snap-fit ​​groove and the baffle are located below the bottom surface of the body. Attached Figure Description

Detailed Implementation

[0045] In existing interactive flat panel designs, the outer casing 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.

[0046] 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.

[0047] To address the aforementioned issues, the inventors of this application previously attempted to integrally mold the frame and back panel, followed by secondary processing of the frame to create the holes and support structures for the corresponding functional components. However, the outer shell components were prone to deformation and damage during secondary processing, significantly reducing the yield rate and consequently impacting production costs. Therefore, the inventors of this application decoupled the installation requirements of the functional components from the frame. Specifically, an external module is detachably installed on the outer surface of the frame to install the functional components. This allows for the installation of different models of functional components by simply replacing the external module, enabling the use of a single outer shell component without reprocessing, thus reducing production costs.

[0048] 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.

[0049] This application provides an interactive flat panel, which has a display function, or simultaneously has infrared touch and display functions. It should be noted that the interactive flat panel involved in this application may include, but is not limited to, various interactive flat panels such as commercial displays, conference displays, touch all-in-one machines, self-service terminals, human-computer interaction flat panels, televisions, and smart blackboards.

[0050] Please see also Figures 1 to 3 In one feasible implementation, the interactive flat panel may include at least a housing component 100. The housing component 100 serves as the main supporting component of the interactive flat panel, providing support and protection for other components within the panel. Simultaneously, the housing component 100 covers the outer surface of the interactive flat panel, serving as its exterior appearance. Specifically, the housing component 100 may include a back panel 110 and a first frame 120. The back panel 110 covers the back of the interactive flat panel, and the first frame 120 is located at the edge of the back panel 110, covering the outer side and front edge of the interactive flat panel.

[0051] The interactive flat panel also includes an external module 200. The external module 200 has a mounting cavity 210 for mounting functional components, and is detachably connected to the outer casing 100. That is, in this embodiment, functional components are mounted on the external module 200, and the external module 200 is detachably connected to the first frame 120. Thus, when facing the installation requirements of different models of functional components, the installation requirements of different models of functional components can be met by replacing the external module 200. At this time, only the connection method between different external modules 200 and the outer casing 100 needs to be matched, allowing them to share a single outer casing 100, thereby eliminating the need for reprocessing the outer casing 100 and reducing production costs. Especially for the one-piece molding of the outer casing 100, the overall mold opening cost of the outer casing 100 is expensive. If separate molds are made for different models of functional components, it will result in a significant cost waste. The functional components can be cameras, speakers, light sensors, and proximity sensors, etc.

[0052] In this embodiment, the external module 200 should be located on the outer surface of the first frame 120, so that the functional components mounted on the external module 200 can face the front of the interactive flat panel, thereby enabling the functional components to be used normally. For example, when the functional component is a camera, the camera needs to face the front of the interactive flat panel to be used normally.

[0053] In one feasible implementation, the external module 200 can extend along the length of the first border 120, with both ends of the external module 200 adjacent to the ends of the first border 120. This allows the external module 200 to be made as large as possible to accommodate a greater number of functional components. Furthermore, as the length of the external module 200 increases, its vertical height can be correspondingly reduced, thus preventing it from being too abrupt and affecting the aesthetics of the interactive flat panel. In addition, the external module 200 essentially covers one side of the interactive flat panel, creating a continuous visual effect and further enhancing its aesthetics.

[0054] In practical applications, interactive whiteboards are typically rectangular in shape, with borders on all four sides: a top border, a bottom border, and two side borders. It's important to note that when the interactive whiteboard is in use, from the viewing side, the border at the top of the whiteboard is the top border, the border at the bottom is the bottom border, and the borders on either side are the side borders.

[0055] The aforementioned first border 120 can be one of the top border, bottom border, and side border. That is to say, the external module 200 can be connected to the top border, bottom border, or side border, without being specifically limited here.

[0056] Preferably, the first frame 120 can be a top frame, so that the external module 200 located on the outer surface of the first frame 120 can have sufficient height to better meet the usage requirements of the functional components installed within the external module 200. For example, when the functional component is a camera, the height provided by the external module 200 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.

[0057] In practical applications, the external module 200 can be located on the front or top surface of the first frame 120. However, considering that the front of the first frame 120 is relatively narrow and cannot meet the width requirements of some functional components, and that when the external module 200 is located on the front of the first frame 120, the external module 200 protrudes from the viewing side of the interactive flat panel towards the user, which may affect the overall aesthetics of the interactive flat panel.

[0058] Therefore, this application preferably uses an external module 200 located on the top surface of the first frame 120. Specifically, as shown... Figures 1 to 3 As shown, the first frame 120 has an outer segment 121, which is located at the top of the first frame 120. The external module 200 is at least partially supported on the outer segment 121, meaning that the external module 200 is at least partially located on the top surface of the first frame 120. In this way, the first frame 120 can have sufficient width to meet the installation requirements of the external module 200, and the external module 200's placement on the top surface of the first frame 120 also prevents it from appearing too obtrusive, improving the aesthetics of the interactive flat panel.

[0059] Furthermore, the first frame 120 can also support the external module 200 through the outer segment 121, so that the connection between the external module 200 and the housing component 100 does not need to bear the overall force of the external module 200, thereby avoiding the risk of the external module 200 accidentally falling off due to excessive weight. At the same time, it reduces the strength requirements of the connection between the external module 200 and the housing component 100, simplifying the installation complexity.

[0060] In one feasible implementation, the external module 200 includes a body portion 220. The body portion 220 is constructed as a hollow structure, that is, the body portion 220 surrounds and forms the aforementioned mounting cavity 210, and the external module 200 is snapped onto the outer segment 121 through the bottom surface of the body portion 220. In this way, when the body portion 220 is installed on the outer segment 121 by snapping, the connection between the body portion 220 and the outer segment 121 is concealed by the body portion 220, thereby achieving a hidden connection and improving aesthetics.

[0061] In practical applications, the external module 200 is an injection-molded part, which can be manufactured through injection molding to reduce production costs. Of course, the external module 200 can also be a metal part, manufactured through aluminum extrusion or bending. When the external module 200 is an injection-molded part, the connection method of the external module 200 via the snap-fit ​​between the body part 220 and the outer segment 121 allows for space for thermal expansion and contraction, avoiding the problem of localized deformation of the external module 200 due to thermal expansion and contraction caused by screw connections.

[0062] The back panel 110 and the first frame 120 can be designed separately and then connected to each other.

[0063] Of course, the back panel 110 and the first frame 120 can also be integrally formed, thus eliminating the need for additional assembly of the back panel 110 and the first frame 120, simplifying the production process, and also optimizing the splicing gap between the back panel 110 and the first frame 120 to improve the aesthetics of the interactive flat panel. Preferably, the back panel 110 and the first frame 120 can also be integrally formed, and this will be described subsequently.

[0064] For details regarding the integrated structure of the back panel 110 and the first frame 120, please refer again. Figure 3 As shown, in one feasible embodiment, a first planar segment 111 is formed at the front end of the back panel 110, and a first frame 120 is L-shaped and located outside the first planar segment 111. Specifically, the first frame 120 also includes a front side segment 122, which, together with the outer side segment 121, forms an L-shape. The outer side segment 121 extends from the outer side of the first planar segment 111 in a direction away from the back panel 110, and is substantially perpendicular to the first planar segment 111. The front side segment 122 extends inward from the first end of the outer side segment 121 away from the first planar segment 111 in a direction perpendicular to the outer side segment 121.

[0065] In practical applications, when the first frame 120 is the top frame, the aforementioned "extending from the outside of the first planar segment 111 in a direction away from the back panel 110" is equivalent to "extending from the top of the first planar segment 111 in a forward direction," and "extending inward along a direction perpendicular to the outer segment 121" is equivalent to "extending downward along a direction perpendicular to the outer segment 121." The outer segment 121, the front segment 122, and the first planar segment 111 together form a receiving cavity 123. This receiving cavity 123 can be used to install touch components, so that the interactive flat panel integrates infrared touch function and display function into one unit. The first frame 120 can be formed by bending the outer periphery of the first planar segment 111 twice. The first frame 120 can also be formed by stamping, stretching, and then bending the first planar segment 111; this application does not specifically limit this.

[0066] It should be noted that the vertical and horizontal directions of this application can be referenced. Figure 3 The arrow direction is shown.

[0067] In one feasible implementation, the front side of the main body 220 is approximately flush with the front side of the front section 122. This ensures that the viewing side of the interactive flat panel is relatively flat, reducing splicing gaps or stepped surfaces and maintaining the aesthetics of the interactive flat panel. Simultaneously, it avoids the problem of the main body 220 casting shadows on the display area of ​​the interactive flat panel under external light sources when the front side of the main body 220 protrudes from the front side of the front section 122, thus preventing poor usability.

[0068] Please see also Figure 1 ,as well as Figures 3 to 5 As shown, in one feasible embodiment, the rear side of the main body 220 is provided with a skirt 230. The skirt 230 extends towards the outer shell component 100 and abuts against the rear side of the first planar segment 111. This allows for the installation of the external module 200 by referring to the abutment between the skirt 230 and the rear side of the first planar segment 111, enabling quick positioning and installation of the external module 200 and reducing the possibility of misalignment. Simultaneously, the abutment between the skirt 230 and the rear side of the first planar segment 111 also allows for interference between the skirt 230 and the first planar segment 111, preventing the external module 200 from flipping forward or backward, thus avoiding the external module 200 from falling off under force and ensuring installation stability.

[0069] In practical applications, the skirt 230 can be arranged continuously or intermittently along the entire length of the body 220, or it can be arranged at a specific location on the body 220. The skirt 230 can be integrally formed with the body 220, or it can be formed separately and then connected.

[0070] The external module 200 can be detachably connected to the housing component 100 using the aforementioned snap-fit ​​method. Alternatively, the external module 200 can also be detachably connected to the housing component 100 using fasteners. Or, the external module 200 can be detachably connected to the housing component 100 using a combination of snap-fit ​​and fastener connections, employing a dual connection to ensure connection stability.

[0071] Regarding the specific structure of the external module 200 connected to the housing component 100 using fasteners, in one feasible embodiment, the skirt 230 can be connected to the first planar segment 111 via fasteners. Alternatively, the bottom surface of the skirt 230 is provided with a lug 231, which is connected to the first planar segment 111 via fasteners. Regardless of the connection method used, the fasteners are located on the back of the interactive flat panel, i.e., on an infrequently seen surface, or in other words, not visible during normal use of the interactive flat panel, thereby avoiding exposure of the connection and improving aesthetics.

[0072] In practical applications, when the bottom surface of the skirt 230 is provided with a lug 231, there can be multiple lugs 231. Multiple lugs 231 are spaced apart along the length direction of the skirt 230. Correspondingly, there can also be multiple fasteners. Multiple fasteners pass through multiple lugs 231 and are connected to the first planar segment 111.

[0073] The aforementioned body portion 220 can be engaged with the outer segment 121 in a vertical direction. The aforementioned body portion 220 can also be engaged with the outer segment 121 in a horizontal direction. However, considering that the outer segment 121 is often thinner when the outer shell component 100 is integrally formed, if the body portion 220 is engaged with the outer segment 121 in a vertical direction, the contact area between the body portion 220 and the outer segment 121 is often small, which can lead to excessive force concentration and unstable connection between the external module 200 and the outer shell component 100.

[0074] Therefore, this application preferably employs a body portion 220 that engages with the outer side portion 121 in the horizontal direction. For details, please refer to [link to relevant documentation]. Figures 5 to 8 As shown, in one feasible embodiment, the bottom surface of the main body 220 is provided with a snap-fit ​​portion 240. The snap-fit ​​portion 240 has a snap-fit ​​groove 241 along a side parallel to the main body 220, and a baffle 242 is formed below the snap-fit ​​groove 241. The outer segment 121 is provided with a first snap-fit ​​hole 1211. The first snap-fit ​​hole 1211 has an insertion area 12111 and a snap-fit ​​area 12112 arranged along the length direction of the outer segment 121. The inner side of the first snap-fit ​​hole 1211 located at the snap-fit ​​area 12112 is provided with a snap-fit ​​block 1212 that mates with the snap-fit ​​groove 241. The size of the insertion area 12111 is slightly larger than the size of the snap-fit ​​portion 240, so that the snap-fit ​​portion 240 can be inserted into the insertion area 12111. The end of the snap-fit ​​part 240 away from the snap-fit ​​groove 241 is a fixed end, which is connected to the main body part 220. The end of the snap-fit ​​part 240 adjacent to the snap-fit ​​groove 241 is a free end, which can undergo elastic deformation relative to the fixed end under force.

[0075] See details Figure 1 , Figure 3 , Figure 5 and Figure 7 ,as well as Figure 8 The schematic diagram of the latching process of the latching part 240 shown shows that when the latching part 240 is inserted into the insertion area 12111, the main body 220 moves toward the latching area 12112. The latching block 1212 can force one end of the latching part 240 adjacent to the latching groove 241 to move away from the latching block 1212, so that the latching block 1212 is inserted into the latching groove 241. The baffle 242 moves to the bottom of the latching block 1212, thereby limiting the latching block 1212 by the baffle 242 and preventing the external module 200 from disengaging from the outer shell component 100 upward.

[0076] It is worth mentioning that when the external module 200 attempts to detach from the outer casing 100 upwards, the top surface of the latch 1212 and the bottom surface of the baffle 242 are in contact with each other. That is, the force-bearing surface between the external module 200 and the outer casing 100 is the contact surface between the main body 220 and the outer segment 121. This increases the contact area between the main body 220 and the outer segment 121, improves the upper limit of the destructive force that can be withstood, and avoids the external module 200 from detaching from the outer casing 100 due to accidental force. At the same time, compared with the method of the main body 220 latching with the outer segment 121 in a vertical direction, in this embodiment the main body 220 latches with the outer segment 121 in a horizontal direction, which can reduce the length of the latching part 240 extending into the receiving cavity 123, thereby avoiding interference between the latching part 240 and the touch component installed in the receiving cavity 123.

[0077] In practical applications, the main body 220 may have multiple snap-fit ​​portions 240, which are spaced apart along the length of the main body 220. Correspondingly, the outer segment 121 may also have multiple first snap-fit ​​holes 1211, which are arranged corresponding to the multiple snap-fit ​​portions 240, so that the multiple snap-fit ​​portions 240 respectively snap into the multiple first snap-fit ​​holes 1211, thereby improving connection stability.

[0078] In one feasible implementation, the snap-fit ​​portion 240 can protrude completely from the bottom surface of the body portion 220, and the end of the snap-fit ​​portion 240 away from the snap-fit ​​groove 241 is connected to the bottom surface of the body portion 220, that is, the fixing section of the snap-fit ​​portion 240 is connected to the bottom surface of the body portion 220.

[0079] like Figure 3 and Figure 5As shown, in another optional embodiment, the bottom surface of the main body 220 is provided with a second snap-fit ​​hole 221. One end of the snap-fit ​​portion 240 away from the snap-fit ​​groove 241 is connected to the inner side surface of the second snap-fit ​​hole 221, and the snap-fit ​​portion 240 partially protrudes from the bottom surface of the main body 220. It is understood that, compared to a snap-fit ​​portion 240 that can completely protrude from the bottom surface of the main body 220, in this embodiment, the snap-fit ​​portion 240 can also extend into the second snap-fit ​​hole 221, thereby increasing the thickness of the snap-fit ​​portion 240, reducing the possibility of breakage due to elastic deformation of the snap-fit ​​portion 240, and improving the service life of the snap-fit ​​portion 240.

[0080] The height 'a' of the snap-fit ​​groove 241 below the bottom surface of the main body 220 should not be less than the thickness of the snap-fit ​​block 1212. In this way, when the snap-fit ​​part 240 is inserted into the insertion area 12111 and moves toward the snap-fit ​​area 12112, the snap-fit ​​block 1212 can be snapped into the snap-fit ​​groove 241.

[0081] The aforementioned external module 200 can be manufactured as a single piece.

[0082] However, considering that the external module 200 is made in one piece, its overall length is relatively long, making it inconvenient for processing supplied materials, and that when the external module 200 is manufactured using injection molding, demolding is difficult. Therefore, the external module 200 can also be made using a multi-segment splicing method. Specifically, such as... Figure 1 , Figure 5 and Figure 9 As shown, in one feasible implementation, the external module 200 is composed of at least two splicing segments, and the splicing surface of two adjacent splicing segments is approximately perpendicular to the length direction of the external module 200. That is, the external module 200 is composed of multiple shorter splicing segments manufactured separately and then spliced ​​together, thereby facilitating the processing of each splicing segment and the transportation of incoming materials, and reducing production costs.

[0083] In practical applications, multiple splicing segments can be first assembled to form an external module 200, and then installed as a whole on the outer casing component 100. Each splicing segment can also have a corresponding connecting component (at least one of a lug 231, a snap-fit ​​part 240, and a skirt 230), with each segment individually connected to the outer casing component 100 to form the external module 200. The splicing surfaces of adjacent segments can have mating structures, such as inserts and slots, to reduce the splicing gap or segment difference after the two segments are joined.

[0084] Taking the external module 200, which is composed of three spliced ​​segments, as an example, Figure 1 and Figure 9As shown, the three splicing segments are the first splicing segment 250, the second splicing segment 260, and the third splicing segment 270. The second splicing segment 260 is located between the first splicing segment 250 and the third splicing segment 270, and the first splicing segment 250 and the third splicing segment 270 are spliced ​​to the two ends of the second splicing segment 260, respectively.

[0085] In this embodiment, the second splicing segment 260 can be a tubular structure, and the internal cavity of the second splicing segment 260 extends through both ends of the second splicing segment 260. When the first splicing segment 250 and the third splicing segment 270 are spliced ​​with the second splicing segment 260, the first splicing segment 250 and the third splicing segment 270 are connected to the second splicing segment 260 through both ends of the second splicing segment 260, so as to facilitate the internal wiring connection arrangement of the first splicing segment 250, the second splicing segment 260 and the third splicing segment 270.

[0086] Furthermore, both the first splicing segment 250 and the third splicing segment 270 have a downwardly sloping transition surface 271 at the end furthest from the second splicing segment 260, so that the two ends of the external module 200 transition with the two sides of the interactive flat panel through the transition surface 271, thereby improving the aesthetics of the interactive flat panel. The transition surface 271 can be a sloping surface or a curved surface.

[0087] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the housing component 100 may further include a second frame 130 and a third frame 140, which are located at both ends of the first frame 120 and are parallel and opposite to each other, serving as side frames. In practical applications, the back panel 110, the first frame 120, the second frame 130, and the third frame 140 may be integrally formed.

[0088] Based on the same inventive concept, this application also provides an external module 200, which can be used as a separate component. The external module 200 includes a body portion 220 and a snap-fit ​​portion 240 located on the bottom surface of the body portion 220. The body portion 220 encloses a mounting cavity 210 for mounting functional components, and the bottom surface of the body portion 220 has a second snap-fit ​​hole 221. The snap-fit ​​portion 240 is located within the second snap-fit ​​hole 221 and partially protrudes from the bottom surface of the body portion 220. One end of the snap-fit ​​portion 240 is connected to the inner side surface of the second snap-fit ​​hole 221. The snap-fit ​​portion 240 has a snap-fit ​​groove 241 with an opening facing the side surface of the snap-fit ​​portion 240, and a baffle 242 is formed below the snap-fit ​​groove 241. At least a portion of the snap-fit ​​groove 241 and the baffle 242 are located below the bottom surface of the body portion 220.
