Description

Technical Field

[0001] The utility model relates to the technical field of display devices, and in particular to a frame component structure and an interactive flat panel. Background Art

[0002] The structure of current display devices (such as conference interactive tablets) is generally composed of three parts: a backlight module, a frame assembly, and a display module.

[0003] As for the frame assembly, as the supporting base of the display device, the frame assembly needs to bear the weight of the backlight module and the display module at the same time. Therefore, the frame assembly needs to have sufficient structural strength to ensure that the relevant material components can be stably supported on the display device.

[0004] However, it is often difficult to strike a balance between the structural strength, processing efficiency and cost of frame components. Frame components with higher structural strength have relatively higher processing efficiency and cost, while frame components with relatively lower processing efficiency and cost will also have lower structural strength and dimensional accuracy, which is not conducive to mass production of products and is difficult to meet user needs. Utility Model Content

[0005] The purpose of the embodiments of the utility model is to provide a frame component structure and an interactive flat panel to solve the problems of high cost and weak structural strength of the frame body.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, a frame component structure is provided, which is applied to a display device, including:

[0008] A frame body, wherein a hollow cavity is formed inside the frame body, wherein the frame body is provided with a first support plate portion located at the front side of the cavity and a second support plate portion located at the rear side of the cavity, and the first support plate portion and the second support plate portion are located at the inner side of the frame body and are spaced apart to form a cavity opening communicating with the cavity; and

[0009] There are multiple reinforcing connectors, and the multiple reinforcing connectors are arranged at intervals along the length direction of the frame body. Each of the reinforcing connectors is located on the inner side of the frame body. The reinforcing connectors are respectively fixedly connected to the first support plate portion and the second support plate portion to cover at least part of the cavity opening, so that the frame body forms a sealed cross-sectional shape, thereby maintaining a high structural strength of the frame body and improving the deformation of the frame body caused by its own stress and external force under normal conditions and under stress.

[0010] In a second aspect, an interactive tablet is provided, comprising:

[0011] It comprises the frame assembly structure as described in the first aspect, wherein the frame body encloses and defines an installation area;

[0012] The screen assembly covers the installation area, a part of the screen assembly is installed on the frame body, and the other part of the screen assembly is installed on the reinforcing connector. This reduces the various costs of the frame body and improves its processing efficiency, thereby improving the overall strength of the frame assembly and the display device, which is beneficial to batch processing of products and can also meet user needs.

[0013] The beneficial effects of the utility model are as follows: the frame assembly structure adopts a frame body structure with an open cross-section to reduce the processing cost and material cost of the frame body;

[0014] Furthermore, by providing a plurality of reinforcing connectors at the opening of the frame body and arranged at intervals along its length direction, the frame body forms a sealed cross-sectional shape, thereby allowing the frame body to maintain a high structural strength, thereby improving the deformation of the frame body under normal conditions and under stress due to its own stress and external forces. While reducing various costs of the frame body and improving its processing efficiency, the overall strength of the frame assembly and the display device is improved, which is beneficial to batch processing of products and can also meet the user's usage needs.

DETAILED DESCRIPTION

[0026] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0029] The structure of current display devices (such as conference interactive tablets) is generally composed of three parts: a backlight module, a frame assembly, and a display module.

[0030] As for the frame assembly, as the supporting basis of the display device, the frame assembly needs to bear the weight of the backlight module and the display module at the same time. Therefore, the frame assembly needs to have sufficient structural strength to ensure that the relevant material components can be stably supported on the display device. From the background technology, it can be seen that it is often difficult to strike a balance between the structural strength, processing efficiency and cost of the frame assembly. The frame assembly with higher structural strength has relatively high processing efficiency and cost, and it is difficult to reduce the product price, which cannot meet the needs of different consumers. The frame assembly with relatively low processing efficiency and cost will also have a lower structural strength and dimensional accuracy, which is not conducive to mass production of the product and is difficult to meet the user's usage needs. At present, the frame assemblies of display devices can be mainly divided into the following schemes:

[0031] 1. Aluminum profile frames are initially formed by extrusion process and then processed by milling process. The frames are connected to each other by corner parts.

[0032] 2. Iron frame, formed by sheet metal processing, the frame assembly can be a one-piece piece, or the frames formed separately can be connected to each other by screws or corner parts;

[0033] 3. The iron frame is formed by rolling process. The frame assembly can be an integrated piece, or the frames formed separately can be connected to each other by screws or corner parts.

[0034] Taking the general display device structure as an example, the functional modules configured by the display device are mainly arranged on the lower frame (or upper frame, of course, in other embodiments, it is not excluded that the functional modules are mainly arranged on the left or right frame). In order to provide installation space and disassembly position of each functional module, the lower frame usually has more structural features. With regard to the situation mentioned in the background technology, combined with the above-mentioned frame component solutions, it can be known that although the dimensional accuracy of the aluminum profile frame is relatively high, and the closed cross-sectional shape has a high structural strength, the frame component processed by this process has a low processing efficiency, and its material cost and process cost are also relatively high. High; and the iron frame formed by sheet metal processing has a lower process cost than the aluminum profile frame, but for large-sized frame materials of the whole machine, the dimensional accuracy of the frame formed by the sheet metal process is low, and the overall deformation of the frame component is difficult to control, resulting in a high material defect rate, which ultimately increases the material cost. In addition, the sheet metal process is difficult to form more complex cross-sectional shapes, and the structural strength of the open cross-section is weak; the iron frame formed by the rolling process has higher dimensional accuracy than the sheet metal process, and can form relatively complex cross-sectional shapes, but it still cannot form closed cross-sectional shapes, and the structural strength of the frame component still cannot adapt to display devices with different product requirements.

[0035] To this end, the present embodiment provides a frame component structure that can ensure the strength of the frame structure while also having a relatively low cost. It adopts an open cross-section shape with relatively low material and process costs, and on this basis adds a reinforcing connector 20 to solve the problem of the difficult trade-off between the structural strength, processing efficiency and cost of the frame body 10.

[0036] It should be noted that the frame component structure is mainly used in display devices, among which the display devices have many application scenarios and fields, including but not limited to commercial scenarios, such as: LCD advertising machines, conference display screens 31, LCD splicing screens, touch-in-one machines, outdoor advertising machines, digital smart water signs, self-service terminals, customized commercial displays, etc., all belong to the commercial display category, and teaching scenarios, such as: smart blackboards, multimedia display screens 31, etc., all belong to the teaching category. The display device can be used to output image information, and is mainly composed of a display module, a backlight module and a frame component structure provided in this embodiment. The display module and the backlight module are respectively arranged on the front and rear sides of the frame component structure and are connected to the frame component structure. The display module includes a display screen 31 for providing an image display function. In some embodiments, the display screen 31 includes a liquid crystal panel 312, and a glass panel 311 located on the front side of the liquid crystal panel 312 for protecting the liquid crystal panel 312. The rear side of the liquid crystal panel 312 is supported by the frame component structure. The backlight module and the optical film material are arranged on the rear side of the display module, which are used to provide an image brightness function, and are also installed and fixed on the frame component structure.

[0037] like Figure 1-Figure 5 , Figure 8-Figure 9 As shown, in order to facilitate a more comprehensive understanding of the present solution, taking the application of the frame component structure in the display device as an example, for each component in the frame component structure and other components in the display device, the side close to the center direction of the display screen 31 is the inner side of each component, that is, the "inner" direction indicated by the arrow in the accompanying drawing, and the side away from the center direction of the display screen 31 is the outer side of each component, that is, the "outer" direction indicated by the arrow in the accompanying drawing; and the side of the interactive tablet used to provide the image display function, that is, the side of the interactive tablet that provides the image display when the user is using it, the direction facing is the front side of each component, that is, the "front" direction indicated by the arrow in the accompanying drawing, and on the contrary, the side of the interactive tablet used to set the backlight module (not shown) is regarded as the rear side of each component, that is, the "rear" direction indicated by the arrow in the accompanying drawing.

[0038] It should also be noted that in the application of display devices, the frame component structure serves as the supporting basis for the display module and the backlight module. The frame component structure can be composed of multiple frame components that are spliced ​​together and enclosed according to the product structure of the display device, or an integrally formed frame structure can be adopted. The frame shape and the number of frame components used when multiple frame components are adopted can be determined based on factors such as process requirements and product requirements of the display device, and this embodiment does not make specific limitations on this.

[0039] Please refer to the attached Figure 1-Figure 9The frame assembly structure includes a frame body 10 as a supporting base for the structure and the display device. According to the above description, it can be understood that in order to effectively control the cost of the frame assembly structure, the frame body 10 used in this embodiment is an open cross-sectional shape, that is, the frame body 10 can adopt the above-mentioned iron frame, and according to the specific product requirements, the sheet metal or rolling process is selected to realize the molding of the frame body 10. The open cross-sectional shape means that a hollow cavity 14 is formed inside the frame body 10, and the cavity 14 can be through the opposite ends of the frame body 10 along the length direction of the frame body 10, and on one side of the frame body 10, a cavity 141 is formed, which is also opened along the length direction of the frame body 10 and connects the cavity 14 and the external environment of the frame body 10. That is, in the length direction of the frame body 10, the frame body 10 is not closed, but an open structure connected to the outside of the frame body 10 through the cavity 141 formed on one side of the frame body 10. It should be understood that the opening formed on the frame body 10 is not opened through a subsequent processing process after the frame body 10 is processed and formed, but is formed during the process of processing and forming through a sheet metal process or a rolling process.

[0040] On the basis of the above, the frame body 10 is surrounded by a support plate of a plate-like structure to form a cavity 14 and a cavity opening 141 connected to the cavity 14. Specifically, the frame body 10 is provided with a first support plate portion 11 located on the front side of the cavity 14 and a second support plate portion 12 located on the rear side of the cavity 14. It should be understood that the cross-sectional shape of the frame body 10 can vary according to the structural form of the display device, that is, the surface structure of the first support plate portion 11 and the second support plate portion 12 can be, in addition to being a plane, a curved surface or other irregular shapes. In this embodiment, the first support plate portion 11 and the second support plate portion 12 are taken as an example of a flat plate structure. It can be known from the above scheme that the frame body 10 encloses a structural form with a cavity 14 formed inside, that is, on the basis of providing the first support plate portion 11 and the second support plate portion 12, the outer sides of the first support plate portion 11 and the second support plate portion 12 are connected by an appearance plate portion 15, so that the first support plate portion 11, the appearance plate portion 15 and the second support plate portion 12 are connected in sequence to form an open cross-sectional form, the first support plate portion 11 and the second support plate portion 12 are arranged opposite to each other, and the first support plate portion 11 and the second support plate portion 12 are located on the inner side of the frame body 10 to form a cavity opening 141 connected to the cavity 14.

[0041] Exemplarily, on the basis that the first support plate portion 11 and the second support plate portion 12 are flat plates, the appearance plate portion 15 of the above embodiment can also be set as a flat plate, and between the first support plate portion 11 and the appearance plate portion 15, and between the second support plate portion 12 and the appearance plate portion 15, they can all be set to be perpendicular to each other, so that the cross-section of the frame body 10 forms a shape approximately like a "凵".

[0042] In other embodiments, the included angle between the first support plate portion 11 and the appearance plate portion 15, the included angle between the second support plate portion 12 and the appearance plate portion 15, and the structural form of the support plate portion 13 can all vary according to the product requirements of the display device. For example, the first support plate portion 11, the appearance plate portion 15, and the second support plate portion 12 are all arc-shaped and connected to each other, so that the overall cross-sectional shape of the frame body 10 is approximately circular. Another example is that the cross-sectional shape of the frame body 10 can also be other irregular shapes such as a triangle or a trapezoid.

[0043] Please continue to refer to the appendix Figure 2-Figure 9 This frame assembly structure further includes a reinforcing connecting member 20. The reinforcing connecting member 20 is used to connect the first support plate portion 11 and the second support plate portion 12 in this structure to block at least part of the cavity opening 141, so that when the frame body 10 and the reinforcing connecting member 20 cooperate, a closed cross-sectional shape is formed. Compared with the open cross-sectional shape, the closed structure is obviously more stable. Regarding the position where the reinforcing connecting member 20 is provided on the frame body 10, the relative positions of the first support plate portion 11 and the second support plate portion 12 of the frame body 10 are more stable and will not deform under external force and its own stress. It can be understood that the reinforcing connecting member 20 is fixedly connected to the first support plate portion 11 and the second support plate portion 12 respectively to ensure that the reinforcing connecting member 20 will not easily break away from the frame body 10, and any form can be adopted between the reinforcing connecting member 20 and the frame body 10 to achieve their relative fixation, including but not limited to detachable connection (including but not limited to screwing, buckling, abutting, plugging, etc.) and non-detachable connection (including but not limited to welding, bonding, riveting, etc.).

[0044] It is understandable that in order to make the overall structure of the frame along its length direction have higher strength, the general practice is to set the reinforcing connector 20 along the length direction of the frame body 10, and set the length dimension of the reinforcing connector 20 to be consistent or nearly consistent with the frame body 10, so that the frame body 10 is connected to the reinforcing connector 20 at all locations along the length direction. However, since the frame body 10 of this embodiment is formed by a sheet metal process or a rolling process, the frame body 10 will produce certain deformations and certain stresses during the production process, and in the embodiment in which the reinforcing connector 20 is also a long strip structure, the reinforcing connector 20 will also have certain deformations and stresses, which will cause the reinforcing connector 20 to be installed on the frame body 10. The deformation and stress of the two are superimposed on each other, thereby affecting the assembly effect between the reinforcing connector 20 and the frame body 10, and the deformation after the frame body 10 and the reinforcing connector 20 are assembled becomes more uncontrollable, resulting in the display device being unable to meet the assembly requirements of the product.

[0045] In addition, the reinforcing connector 20 of the long strip structure has a small cross-sectional size and a large length, which makes it easier to deform. The production process requires more protection. The large size and the large amount of materials used result in a relatively higher cost for the entire reinforcing connector 20, and a larger production mold is required, which also increases the difficulty of production.

[0046] To this end, the present embodiment adopts the form of a plurality of reinforcing connectors 20, and the plurality of reinforcing connectors 20 are arranged at intervals along the length direction of the frame body 10 to ensure that the frame body 10 can be connected to the reinforcing connectors 20 along its length direction. Thus, by virtue of the fact that each reinforcing connector 20 is located on the inner side of the frame body 10, the cavity 141 at its position is respectively blocked, and the purpose of improving the deformation of the frame body 10 under normal conditions and under stress due to its own stress and external forces is achieved. While reducing various costs of the frame body 10 and improving its processing efficiency, the overall strength of the frame assembly and the display device is improved, which is conducive to batch processing of products and can also meet the user's usage needs.

[0047] In the above-mentioned fact mode, the number and position of the reinforcing connectors 20 on the frame body 10 can be finally determined by comprehensively considering the frame production efficiency, the overall strength, and some avoidance requirements provided by the installation position reserved by the frame body 10 for the functional module, ensuring that the distance between any two adjacent reinforcing connectors 20 meets the structural strength requirements of the frame body 10 and is not prone to local deformation under the action of external force and its own stress.

[0048] Please continue to refer to the attached Figure 5-Figure 9, the frame body 10 is based on the above-mentioned structural form, and a supporting plate portion 13 is arranged on the inner side of the second supporting plate portion 12, the first end of the supporting plate portion 13 is fixedly connected to the second supporting plate portion 12, and the second end of the supporting plate portion 13 is extended to the front side of the second supporting plate portion 12, that is, the second end of the supporting plate portion 13 is extended to the direction close to the first supporting plate portion 11, so that the supporting plate portion 13 and the second supporting plate portion 12 are arranged at an angle, and the second end of the supporting plate portion 13 and the first supporting plate portion 11 are separated to form a cavity 141. As described above, by setting the frame body 10 to a four-sided cross-sectional shape with a cavity 141, the structural strength of the frame assembly can be enhanced to a certain extent. Similarly, the specific structural form of the supporting plate portion 13 is not strictly limited in this embodiment. It can be a flat plate as in the above-mentioned embodiment, or it can be set to other irregular shapes such as arc-shaped plates, as long as it can be located in the cavity 141 of the frame body 10 to form a closing structure, so as to achieve the purpose of improving the structural strength of the frame body 10.

[0049] In addition to the above, the supporting plate portion 13 also serves to improve the assembly stability of the reinforcing connector 20 on the frame body 10. When the reinforcing connector 20 is fixedly connected to the frame body 10, at least part of the supporting plate portion 13 is supported on the outside of the reinforcing connector 20. Specifically, since the supporting plate portion 13 is arranged on the frame body 10 near the second supporting plate portion 12, when the supporting plate portion 13 cooperates with the reinforcing connector 20, the supporting plate portion 13 is supported on the rear side of the reinforcing connector 20. While the supporting plate portion 13 is provided to support the reinforcing connector 20 and improve the stability of the reinforcing connector 20, the supporting plate portion 13 also achieves the purpose of improving the assembly stability of the reinforcing connector 20 on the frame body 10 by increasing the contact surface between the frame body 10 and the reinforcing connector 20, and by improving the assembly strength between the reinforcing connector 20 and the frame body 10, the structural strength of the frame assembly is improved.

[0050] Continuing with the example of the implementation in which the frame body 10 is provided with a supporting plate portion 13, the structure of the reinforcing connector 20 can be set to be adapted to a structural form between the second support plate portion 12 and the supporting plate portion 13, so as to achieve the purpose of increasing the contact surface between the reinforcing connector 20 and the frame body 10 and enhancing the stability of the reinforcing connector 20 on the frame body 10.

[0051] like Figure 5-Figure 9As shown, the second end of the supporting plate portion 13 is extended toward the front side of the second supporting plate portion 12 so that the two are arranged at an angle. The reinforcing connecting member 20 includes a first connecting plate portion 21 and a second connecting plate portion 22 arranged at an angle. The angle between the first connecting plate portion 21 and the second connecting plate portion 22 is equal to the angle between the second supporting plate portion 12 and the supporting plate portion 13.

[0052] Taking the above-mentioned implementation mode in which the supporting plate portion 13 and the second supporting plate portion 12 are perpendicular to each other as an example, the first connecting plate portion 21 and the second connecting plate portion 22 are also configured to be perpendicular to each other, so that the structure between the supporting plate portion 13 and the second supporting plate portion 12 is consistent with the structure between the first connecting plate portion 21 and the second connecting plate portion 22, thereby achieving the purpose of supporting the reinforcing connector 20 and increasing the contact surface between the frame body 10 and the reinforcing connector 20.

[0053] Based on the above structure, in the specific assembly state of the frame body 10 and the reinforcement connector 20, taking the state in which the display device is placed in the vertical direction as an example, the second support plate portion 12 is arranged in the vertical direction, and the supporting plate portion 13 is arranged in the horizontal direction. In order to make the shape of the reinforcement connector 20 compatible with the frame body 10, similarly, the reinforcement connector 20 is also arranged in a state in which the first connecting plate portion 21 is arranged in the vertical direction and the second connecting plate portion 22 is arranged in the horizontal direction, so that the first connecting plate portion 21 can be fixedly connected to the second support plate portion 12, and at least a portion of the second connecting plate portion 22 is mounted on the inner side of the supporting plate portion 13, and the side of the second connecting plate portion 22 facing away from the first connecting plate portion 21 is fixedly connected to the first support plate portion 11.

[0054] It can be understood that in the above-mentioned assembly method, in order to facilitate the installation of the reinforcement connector 20 on the frame body 10, the first connection plate portion 21 is located on the rear side of the second support plate portion 12. Such a setting can allow the first connection plate portion 21 to be set parallel to the second support plate portion 12, while the second connection plate portion 22 is also set parallel to the supporting plate portion 13, so that the reinforcement connector 20 increases the contact area between the frame body 10 and the reinforcement connector 20 by respectively abutting against the rear side of the second support plate portion 12 by the first connection plate portion 21 and against the outer side of the supporting plate portion 13, thereby improving the assembly stability of the reinforcement connector 20 on the frame body 10 and the overall structural strength of the frame assembly. The first connecting plate portion 21 can also be extended forward along the inner side of the frame body 10, and the second connecting plate portion 22 can be located on the inner side of the supporting plate portion 13 and supported by the supporting plate portion 13. At the same time, the problem of interference between the second connecting plate portion 22 and the supporting plate portion 13 caused by setting the first connecting plate portion 21 on the inner side of the second supporting plate portion 12 can be avoided.

[0055] According to any of the above-mentioned embodiments, it can be known that on the basis of reinforcing the strength of the frame body 10 by means of a plurality of reinforcing connectors 20 arranged at intervals, the reinforcing connector 20 can be set as a plate extending along the length direction of the frame body 10. It should be understood that the length dimension of the reinforcing connector 20 should be set to be smaller than the length dimension of the frame body 10. In addition to avoiding the stress superposition and other related problems mentioned above, it is also necessary to satisfy the conditions that a plurality of reinforcing connectors 20 are arranged on the frame body 10, and the reinforcing connectors 20 are arranged at intervals along the length direction of the frame body 10. By increasing the contact surface between each reinforcing connector 20 and the frame body 10, so that the reinforcing connector 20 and the frame body 10 are mutually supported and connected along the length direction, the deformation constraint strength of the reinforcing connector 20 on the frame body 10 is enhanced, and the purpose of improving the strength of the frame body 10 is achieved. It is ensured that a series of problems such as stress superposition between the reinforcing connector 20 and the frame body 10 and uncontrollable deformation of the frame body 10 are avoided.

[0056] The reinforcing connector 20, which has a length much smaller than that of the frame body 10, will not be deformed or have a large stress problem during processing due to its small size, and can effectively avoid the stress superposition between it and the frame body 10. At the same time, the size of the mold used is relatively small, which avoids the problem of increased cost of the reinforcing connector 20 and increased processing difficulty.

[0057] In the above embodiment, it can be known that due to the small size of the reinforcing connector 20, the first connecting plate portion 21 and the second connecting plate portion 22 can be formed by a sheet metal process with relatively lower processing costs. For example, the first connecting plate portion 21 and the second connecting plate portion 22 can be formed by bending processes, stamping processes, etc. in sheet metal. Of course, the reinforcing connector 20 does not exclude the use of other methods in sheet metal processes, or other processing methods other than sheet metal processes.

[0058] Based on any of the above embodiments, the following is an assembly method between the reinforcing connector 20 and the frame body 10, such as Figure 5 , Figure 7 As shown, the rear side of the reinforcing connector 20 is provided with first mounting holes 211 spaced apart along its length direction, and the second supporting plate portion 12 is provided with a plurality of second mounting holes 121 spaced apart along the length direction of the frame body 10 .

[0059] In the above, in the implementation manner in which the reinforcing connector 20 is respectively matched with the second support plate portion 12 and the supporting plate portion 13 of the frame body 10 through the first connecting plate portion 21 and the second connecting plate portion 22, a first mounting hole 211 located on the rear side of the reinforcing connector 20 is opened on the first connecting plate portion 21, so that when the second connecting plate portion 22 is supported by the supporting plate portion 13, the first mounting hole 211 on the first connecting plate portion 21 can be aligned with the second mounting hole 121 on the second supporting plate portion 12, so that the two can subsequently install the first mounting hole 211 and the second mounting hole 121 through a fixing component (not shown) to complete the assembly of the reinforcing connector 20 and the frame body 10.

[0060] A first mounting hole 211 and a second mounting hole 121 are respectively provided on the rear side of the reinforcing connector 20 and the second support plate portion 12, so that the reinforcing connector 20 and the rear side of the frame assembly can be pre-positioned and matched through the first mounting hole 211 and the second mounting hole 121, so as to facilitate the subsequent assembly of the reinforcing connector 20 and the first support plate portion 11. The first mounting hole 211 and the second mounting hole 121 are respectively arranged on the rear side of the reinforcing connector 20 and the frame body 10. The reason is that the installation space between the first support plate portion 11 and the reinforcing connector 20 is relatively small (due to the existence of other components of the display device, such as the display screen 31), which makes it difficult to align the front side of the reinforcing connector 20 with the first support plate portion 11. In addition, in the application of the display device, the front side of the first support plate portion 11 is the appearance surface of the display device, and it is not easy to damage its appearance surface by processing positioning holes, thereby affecting the overall visual effect of the product. Therefore, by connecting the second support plate portion 12 with the reinforcing connector 20, personnel can pre-position the two at the rear side of the frame body 10 and the reinforcing connector 20 where the installation space is larger, so that a relatively stable position state is formed between the first support plate portion 11 and the reinforcing connector 20, so as to facilitate the subsequent further assembly and connection of the two.

[0061] In the above embodiment, the first mounting hole 211 and the second mounting hole 121 are used to provide space for the fixing component to pass through, and can be fixedly connected by the fixing component. The fixing component fixes the first mounting hole 211 and the second mounting hole 121, thereby fixing the second support plate portion 12 and the reinforcing connector 20.

[0062] Exemplarily, the reinforcing connector 20 and the second support plate portion 12 may be connected by means of screw connection, riveting, plug connection, or the like.

[0063] Exemplarily, in an embodiment in which the reinforcing connector 20 is fixed to the second support plate portion 12 by screwing, the fixing assembly may include a bolt and a nut matching it, and the bolt is screwed together with the nut after passing through the first mounting hole 211 and the second mounting hole 121 in sequence, so that the second connecting plate portion 22 and the second support plate portion 12 are tightly fixed by the screw head of the bolt and the nut; or, the second mounting hole 121 is set as a threaded hole that cooperates with the bolt, so that after the bolt passes through the first mounting hole 211, the two are installed and fixed by screwing with the second mounting hole 121.

[0064] Since the reinforcing connector 20 and the frame body 10 both adopt a plate structure, the structural strength of which is relatively weak. Therefore, in this embodiment, a rivet nut is provided on the second mounting hole 121 so that the bolt can be threadedly engaged with the rivet nut located on the second mounting hole 121 after passing through the first mounting hole 211, thereby completing the installation and cooperation between the first connecting plate portion 21 and the second support plate portion 12.

[0065] When the reinforcing connector 20 is riveted to the second support plate portion 12, the first connection plate portion 21 and the second support plate portion 12 can be relatively fixed by means of rivet screws. Of course, this embodiment does not exclude other assembly methods in addition to the rivet fixing method.

[0066] In the plug-in assembly method, the fixing component can be set as a plug-in component that is compatible with the structure of the first mounting hole 211 and the second mounting hole 121. The plug-in component is inserted into the first mounting hole 211 and the second mounting hole 121 in sequence, and is respectively interference-fitted with the first mounting hole 211 and the second mounting hole 121, thereby completing the assembly and fixation of the first connecting plate portion 21 and the second support plate portion 12.

[0067] By providing a plurality of mounting holes on the second support plate portion 12, the position of the reinforcing connector 20 can be adjusted according to actual needs. In addition, by providing a plurality of mounting holes on the reinforcing connector 20, the connection strength between the reinforcing connector 20 and the second support plate portion 12 can also be selected according to needs.

[0068] As for the implementation method of assembling by rivet nuts and bolts in this embodiment, the reinforcing connector 20 and the frame body 10 are pre-positioned by bolts and rivet nuts, which can save the process of fixing the reinforcing connector 20 and the frame body 10 by customizing a special clamp between the two, thereby effectively improving the assembly efficiency of the reinforcing connector 20 and the frame body 10.

[0069] In addition, by respectively providing a plurality of first mounting holes 211 and second mounting holes 121 spaced apart along the length direction on the first connecting plate portion 21 and the second supporting plate portion 12, the reinforcing connector 20 can also adjust its specific assembly position on the frame body 10 according to the structural form of the display device, thereby avoiding interference with other components in the display device. Moreover, the reinforcing connector 20 can also selectively set the fixing component at any position where the first mounting hole 211 is provided according to the assembly strength requirements between the reinforcing connector 20 and the frame body 10, thereby improving the versatility of the reinforcing connector 20 on different frame bodies 10 and meeting the assembly requirements of different display devices.

[0070] Please continue to refer to the attached Figure 5-Figure 9 On the basis of any of the above-mentioned embodiments, the front side of the reinforcing connector 20 and the rear side of the first support plate portion 11 are fixedly connected by welding. The welding method can ensure that the reinforcing connector 20 and the frame body 10 have a strength that meets the assembly requirements, and can also avoid affecting the appearance of the front side of the first support plate portion 11, thereby improving the overall visual effect of the display device.

[0071] Based on the above-mentioned implementation method of welding the front side of the reinforcing connector 20 to the first support plate portion 11, in this embodiment, the reinforcing connectors 20 located at different positions on the frame body 10 can adjust the welding method and fixing strength between the reinforcing connector 20 and the frame body 10 according to factors such as the external force to be borne by the frame body 10 at the position, and the stress generated. That is, the welding method and fixing strength between the reinforcing connectors 20 located at different positions on the frame body 10 and the frame body 10 can be slightly different. Of course, this implementation method does not exclude the method of using the same welding method to fix each reinforcing connector 20 to the frame body 10.

[0072] Regarding the above-mentioned implementation methods where there are differences in the welding methods between the reinforcing connectors 20 located at different positions of the frame body 10, as Figure 4-Figure 5 As shown, the multiple reinforcing connectors 20 respectively include a first reinforcing member 24 and a second reinforcing member 25, wherein there are two first reinforcing members 24, and the two first reinforcing members 24 are respectively arranged near the opposite ends of the frame body 10 along the length direction to provide structural reinforcement function for the opposite ends of the frame body 10, and the second reinforcing member 25 is arranged between the two first reinforcing members 24. Here, the number of the second reinforcing members 25 can be adjusted and changed according to parameters such as the size of the display device and process requirements, product requirements, etc. Only one second reinforcing member 25 can be arranged between the two first reinforcing members 24, or multiple second reinforcing members 25 arranged at intervals along the length direction of the frame body 10 can be arranged between the two first reinforcing members 24. This embodiment does not make specific limitations on this.

[0073] It should be noted that, because the two opposite ends of the frame body 10 are penetrated by the cavity 14, and the two opposite ends of the frame body 10 need to be connected to another frame body 10, the relative connection of the frame body 10 is subjected to greater external force and external impact. Therefore, this embodiment provides the following welding scheme:

[0074] 1. The first reinforcing member 24 is fully welded to the first supporting plate portion 11, and the second reinforcing member 25 is spot welded to the second supporting plate portion 12. It should be explained that the above-mentioned full welding can also be called "full welding", that is, the contact position between the front side of the first reinforcing member 24 and the first supporting plate portion 11 is fusion welded;

[0075] 2. The first reinforcement piece 24 and the second reinforcement piece 25 are spot-welded to the first support plate portion 11 respectively, and the number of welding points between the first reinforcement piece 24 and the first support plate portion 11 is greater than the number of welding points between the second reinforcement piece 25 and the second support plate portion 12 .

[0076] By implementing any of the above-mentioned welding schemes, the fixing strength between the first reinforcement 24 and the frame body 10 can be made greater than the fixing strength between the second reinforcement 25 and the frame body 10. On the basis that the strength of the structures at the two opposite ends of the frame body 10 is satisfied, the welding strength of the second reinforcement 25 is smaller than that of the first reinforcement 24, so that the assembly cost can be controlled to a certain extent, thereby limiting the overall cost of the display device as much as possible.

[0077] Please refer to the attached Figure 1-Figure 9 The present embodiment also provides an interactive tablet, which adopts the frame component structure of any of the above embodiments. The interactive tablet uses the above frame component structure to reduce costs while ensuring that the structural strength of the entire device meets product requirements, thereby avoiding deformation or even damage to the frame component structure when carrying a display module and a backlight module.

[0078] The interactive tablet can be used as a display device. It can also operate the content displayed on the display screen 31 and realize human-computer interaction through capacitive touch technology, electromagnetic induction technology, etc. It integrates one or more functions of a projector, a whiteboard, a screen, an audio system, a television, and a video conferencing terminal. In actual applications, the hardware part of the interactive tablet is composed of a touch module, a display screen 31 (display module), and an intelligent processing system. It is combined together by an integral structural member and is also supported by a dedicated software system. The display screen 31 cooperates with the touch module to realize the display and touch functions. The user can touch the display screen 31 with a finger or a stylus. The intelligent processing system generates handwriting according to the touch operation input by the user and displays it on the display screen 31, or generates a control operation according to the touch operation input by the user to process the display content on the display screen 31.

[0079] As a specific structural form of an interactive flat panel, the installation area is defined by enclosing a multi-section split frame body 10 or an integrated frame body 10. In one embodiment, the frame body 10 is selectively equipped with a reinforcing connector 20 according to the assembly requirements, stress conditions and other factors of the interactive flat panel. That is, in addition to the scheme that the frame bodies 10 located on each side of the interactive flat panel are all provided with reinforcing connectors 20, and in the case that each frame body 10 is provided with a reinforcing connector 20, different numbers of reinforcing connectors 20 can be selectively selected between each frame body 10 according to its specific stress conditions, and the reinforcing connectors 20 can be assembled at different positions. In addition, the interactive flat panel can also adopt a method in which a part of the frame body 10 is provided with a reinforcing connector 20, and another part of the frame body 10 is not provided with a reinforcing connector 20.

[0080] The screen assembly 30 for realizing the image display function and the above-mentioned human-computer interaction function covers the installation area. This embodiment adopts a method in which a part of the frame body 10 is provided with a reinforcing connector 20, and the other part of the frame body 10 is not provided with a reinforcing connector 20 as an example. Corresponding to this structural form, a part of the screen assembly 30 is directly installed on the frame body 10, and the other part of the screen assembly 30 is installed on the reinforcing connector 20, and is installed and matched with the corresponding frame body 10 through the reinforcing connector 20.

[0081] In the above embodiment, whether the screen assembly 30 is directly mounted on the frame body 10 depends on whether a reinforcing connector 20 is installed on the frame body 10 on the side opposite to the screen assembly 30. Figure 1-Figure 2For example, the frame body 10 of this embodiment is respectively arranged on the upper and lower sides and the left and right sides of the interactive flat panel, and only the frame body 10 located on the lower side of the interactive flat panel is provided with a reinforcing connector 20. Therefore, the upper side and the left and right sides of the screen assembly 30 are directly installed on the frame body 10 on the corresponding side, and the lower side of the screen assembly 30 is installed and coordinated with the corresponding frame body 10 by being installed on the reinforcing connector 20.

[0082] Of course, in other embodiments, it is not excluded that when each frame body 10 is provided with a reinforcing connector 20, the above-mentioned partial screen assembly 30 is directly installed on the frame body 10, and the other partial screen assembly 30 is installed and cooperated with the frame body 10 through the reinforcing connector 20.

[0083] Please continue to refer to the attached Figure 1-Figure 9 , wherein the screen assembly 30 includes a display screen 31. As mentioned above, the display screen 31 is used to provide an image display function for the interactive tablet. According to the above embodiments, in some embodiments, the display screen 31 includes a glass panel 311 for protecting the display screen 31, and a liquid crystal panel 312 located at the rear side of the glass panel 311. In this solution, the liquid crystal panel 312 can be, but is not limited to, an LED (Light Emitting Diode) display screen 31, an OLED (Organic Light-Emitting Diode) display screen 31, an LCD (Liquid Crystal Display) display screen 31, etc. Of course, the display screen 31 can also use other display modes besides liquid crystal.

[0084] In addition, the screen assembly 30 also includes a filter strip 32, wherein the material of the filter strip 32 can be PC (Polycarbonate) or PMMA (polymethy lmethacry l ate). The filter strip 32 is arranged on the surrounding side of the display screen 31 according to the product characteristics of the interactive tablet. The filter strip 32 can be arranged around the display screen 31, or only on any two opposite sides of the display screen 31.

[0085] It can be understood that the filter strip 32 is used to filter out light that interferes with human-computer interaction operations. Therefore, correspondingly, a transceiver 50 is provided in the frame body 10, and the transmitting end of the transceiver 50 is arranged toward the filter strip 32 for emitting and receiving light signals for realizing human-computer interaction operations.

[0086] Specifically, the filter strip 32 is at least partially located on the front side of the glass panel 311, so that the light signal emitted by the transceiver 50 can be arranged on the front side of the glass panel 311, so that when the user touches the display screen 31, it can affect the signal reception of the transceiver 50, thereby triggering the human-computer interaction function.

[0087] Reference Figure 5-Figure 9 This embodiment continues to take the solution in which the frame body 10 of the above-mentioned part is provided with the reinforcing connector 20, and the frame body 10 of the other part is not provided with the reinforcing connector 20 as an example. In order to facilitate the understanding of the solution, this embodiment defines the above-mentioned frame body 10 as a first frame 16 and a second frame 17, that is, the frame body 10 includes a first frame 16 and a second frame 17. The first frame 16 and the second frame 17 can adopt the same or different structural forms, and this embodiment does not make specific limitations on this.

[0088] The first frame 16 and the second frame 17 are connected and enclosed to form an installation area. According to the above explanation of the structural form of the frame body 10, here, the first frame 16 and the second frame 17, and / or the body of the second frame 17 can be an integral part, or a mutually independent split structure can be used to form the above installation area. In the case of a split structure, the number of the first frame 16 and the second frame 17 can also be determined according to the product characteristics of the interactive tablet and user needs. For example, when the outer peripheral shape of the interactive tablet is a rectangle, the total number of the first frame 16 and the second frame 17 can be set to four sections, and the positions of the first frame 16 and the second frame 17 on the interactive tablet can also be adjusted according to different product structures and application scenarios.

[0089] In one embodiment, the first frame 16 and the second frame 17 can be respectively provided in two sections, and the first frame 16 and the second frame 17 are alternately connected to enclose and form an installation area;

[0090] In the present embodiment, the first frame 16 is only set to one section, and the second frame 17 is adapted to be set to three sections. Taking the present embodiment as an example, the first frame 16 is located at the lower side of the interactive flat panel, serving as the lower frame of the interactive flat panel, and the second frame 17 is disposed on the left and right sides and the upper side of the interactive flat panel, serving as the upper frame and left and right side frames of the interactive flat panel. The reinforcing connector 20 is installed on the first frame 16, a part of the filter strip 32 is clamped between the reinforcing connector 20 and the first frame 16, and another part of the filter strip 32 is clamped on the second frame 17.

[0091] The second frame 17 can be processed into a limiting structure for restricting the movement of the filter strip 32 through sheet metal processing. The filter strip 32 located on the second frame 17 can be fixed by the limiting structure. Since the fixing method between the filter strip 32 and the second frame 17 is not the core of the present invention, it will not be described in detail in this embodiment.

[0092] The first frame 16 is provided with a first limiting plate portion 161, which is located on the inner side of the first supporting plate portion 11 and fixedly connected to the first supporting plate portion 11, that is, the first limiting plate portion 161 is located on the front side of the frame body 10. In the above-mentioned scheme in which the first supporting plate portion 11 is arranged as a flat plate arranged in the vertical direction, the first limiting plate portion 161 and the first supporting plate portion 11 are arranged in the same vertical plane. Of course, in other embodiments, the first limiting plate portion 161 and the first supporting plate portion 11 can also be arranged to be an angled structural form. Here, the first limiting plate portion 161 is used to limit the extreme position of the filter strip 32 in the front direction, and plays a certain restraining and limiting role in the installation of the filter strip 32 on the first frame 16.

[0093] Correspondingly, a second limiting plate portion 23 is provided on the rear side of the reinforcing connector 20, and the second limiting plate portion 23 is spaced apart and arranged opposite to the first limiting plate portion 161. Taking the filter strip 32 installed between the reinforcing connector 20 and the first frame 16 as an example, the first limiting plate portion 161 and the second limiting plate portion 23 are both located outside the cavity 14. Since the reinforcing connector 20 is arranged on the inner side of the frame body 10, in the assembled state of the filter strip 32, its outer side can abut against the reinforcing connector 20, and the inner side is used to cooperate with the display screen 31 to support the display screen 31. The weight of the display screen 31 can be transferred to the reinforcing connector 20 through the filter strip 32. Due to the existence of the reinforcing connector 20, a relatively stable structure is formed between it and the frame body 10. Therefore, there will be no problem of deformation of the first frame 16 due to the force transmitted to the reinforcing connector 20.

[0094] The gap size between the first limiting plate portion 161 and the second limiting plate portion 23 is adapted to the size of the filter bar 32 in the front-to-back direction, so that the first limiting plate portion 161 and the second limiting plate portion 23 can respectively abut against the front and back sides of the filter bar 32, thereby cooperating with the reinforcing connector 20 to constrain the movement of the filter bar 32 in all directions.

[0095] In combination with the above-mentioned implementation mode in which the reinforcing connector 20 includes a first connecting plate portion 21 and a second connecting plate portion 22, the reinforcing connector 20 can be formed by sheet metal processing, wherein, as mentioned above, the first connecting plate portion 21 and the second connecting plate portion 22 can be bent so as to be set at an angle, and the above-mentioned second limiting plate portion 23 can be cut out on the second connecting plate portion 22 to have a structure similar to the structure of the second limiting plate portion 23, so that when the first connecting plate portion 21 and the second connecting plate portion 22 are bent, the position of the second limiting plate portion 23 is not affected by the bending process, thereby maintaining a state parallel to the first connecting plate portion 21, and finally forming a plate structure protruding from the inner side of the second connecting plate portion 22, and the reinforcing connector 20 formed in this way also has a cross-sectional shape that is approximately "T" shaped.

[0096] Specifically, the filter bar 32 is at least partially located on the outside of the display screen 31, and the inner side of the filter bar 32 is located on the front side of the display screen 31 and is provided with a platform 321, which is used to abut against the front side of the display screen 31. In order to allow the display screen 31 to be stably supported by the filter bar 32, the interactive flat panel further includes a glass bracket 40, one end of the glass bracket 40 is installed on the rear side of the frame body 10, and the other end of the glass bracket 40 is spaced and arranged opposite to the platform 321, and the rear side of the display screen 31 abuts against the glass bracket 40.

[0097] By implementing the above structure, the display screen 31 can be stably restricted by the filter strip 32 and the glass bracket 40 at the position inside the filter strip 32. In the actual application scenario of the interactive tablet, the interactive tablet is generally placed in the vertical direction, that is, the first frame 16 provided with the reinforcing connector 20 will be located at the lower side of the interactive tablet, and the reinforcing connector 20 supports the display screen 31 through the filter strip 32. In this case, the weight of the display screen 31 will be transferred to the reinforcing connector 20 through the filter strip 32. Since there are multiple reinforcing connectors 20 and they are arranged at intervals along the length direction of the frame body 10, the weight of the display screen 31 can be relatively evenly transferred to each reinforcing connector 20 through the filter strip 32. In other words, the force applied to each reinforcing connector 20 is relatively uniform, thereby ensuring that the force applied to each part of the first frame 16 is also relatively uniform, avoiding the problem of stress concentration causing deformation of the frame body 10.

[0098] In summary, this embodiment achieves the purpose of cost reduction by adopting an open frame body 10 with relatively low process cost and material cost, in combination with a reinforcing connector 20, while ensuring that the structural strength of the frame body 10 can meet the product requirements of the display device. At the same time, the frame component structure can also make the product lighter and reduce transportation costs, which is conducive to mass production of products and meets customer usage needs.
