[0061] The housing part of the related interactive tablet is usually composed of a back plate and four frames mounted around the back plate, wherein the frames are connected with the back plate by screws, and two adjacent frames are connected by a corner piece and a decorative piece through screws. The housing part of the interactive tablet has many parts, and the back plate and the frames need to be connected multiple times, which will cause the assembly process to be too complex, the splicing gap difference to be difficult to control, and the manufacturing cost to be increased. Moreover, the housing part of the interactive tablet has multiple splicing areas, or in other words, multiple splicing gaps, which seriously affects the aesthetic appearance of the interactive tablet.

[0062] In view of the above problems, the present inventors have attempted to integrally form multiple frames by roll forming, and then connect the frames with the back plate, so as to reduce the parts to be assembled, simplify the assembly process, and reduce the splicing gap. However, such a configuration reduces some splicing gaps, but the gap between the frames and the back plate is still difficult to avoid. More importantly, the integrally formed frames surround to form a ring-shaped frame structure, which has poor stability. When subjected to external force, especially concentrated load or uneven load, the integrally formed frames are prone to bending or twisting, which is inconvenient for transportation.

[0063] In order to further reduce the splicing gap and avoid the problem of deformation caused by material transportation, the inventor of the present application attempts to integrally form the frame and the back plate. Specifically, the frame and the back plate can be punched from a whole plate, and the peripheral part is plastically deformed to surround the frame part. In this way, not only the number of parts is reduced and the assembly process is simplified, but also the gap between the frame and the back plate is reduced, and the appearance is improved. At the same time, the whole formed by the back plate and the frame has better stability than the ring structure, and can effectively avoid the problem of easy deformation during material transportation. In addition, the stretch forming method can be used during the punching process to form a part of the flanging structure, and then the flanging structure is bent to form the frame. The flanging structure constitutes part of the frame, thereby improving the connection strength between the frame and the back plate and further avoiding the problem of deformation. In this way, the frame and the back plate are integrally formed, which can improve the appearance while reducing the number of parts, simplifying the assembly process and reducing the production cost.

[0064] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application.

[0065] The present application provides an interactive panel which integrates infrared touch control and display functions. Specifically, the infrared touch control function is realized by a touch component installed on the edge of the interactive panel. The touch component emits and receives infrared rays to form an infrared detection network on the screen surface. When any touch object contacts the screen, the infrared rays on the touch point can be changed to realize touch screen operation. It should be noted that the interactive panel involved in the present application can include but is not limited to various interactive panels such as commercial display screens, conference display screens, touch all-in-one machines, self-service terminals, human-computer interaction panels, televisions, and smart blackboards.

[0066] Please see Figures 1 to 4 In an implementable embodiment, the interactive panel can at least include a back plate 100. The back plate 100 is the main supporting component of the interactive panel, and is mainly used to support and protect other components in the interactive panel. At the same time, the back plate 100 is wrapped on the outer surface of the interactive panel as an appearance part of the interactive panel. Specifically, the back plate 100 includes a back plate body 110 and a bent frame 120. The back plate body 110 and the bent frame 120 are an integral structure, the back plate body 110 and the bent frame 120 are integrally formed, the bent frame 120 is arranged on the outer side of the back plate body 110, and the bent frame 120 and the back plate body 110 form a mounting groove 121. The back plate body 110 covers the back of the interactive panel, and the bent frame 120 covers the side of the interactive panel and the edge of the front of the interactive panel.

[0067] The interactive panel further comprises a touch component 200 and a protective panel 300. The touch component 200 is used for receiving and / or emitting infrared rays, and the touch component 200 is installed in the installation groove 121. The protective panel 300 is a layer of transparent material covering the front of the display component of the interactive panel, and the protective panel 300 is used to protect the display component from dust, moisture, scratches and other potential damage. In actual application, the protective panel 300 can be made of glass or other materials with light transmission and high hardness.

[0068] In the embodiment, the protective panel 300 is installed between the touch component 200 and the back plate body 110, and the protective panel 300 is limited by the touch component 200. In this way, the touch component 200 can limit the protective panel 300 in the back plate 100, and the touch component 200 is at least partially located in front of the protective panel 300, so that the touch component 200 can form an infrared ray detection network on the surface of the protective panel 300.

[0069] The back plate body 110 and the bent frame 120 can be integrally formed by 3D printing, casting, injection molding and plastic deformation. Taking the case where the back plate body 110 and the bent frame 120 are integrally formed by plastic deformation as an example, the bent frame 120 is formed by plastic deformation of the periphery of the back plate body 110.

[0070] It is worth mentioning that, compared with the related art, the shell part of the interactive panel is composed of a back plate and four frames located around the back plate, the back plate 100 of the present application is composed of the back plate body 110 and the bent frame 120, and the back plate body 110 and the bent frame 120 are an integral structure. This not only reduces the number of parts to be assembled, simplifies the assembly process, reduces production costs, facilitates quality control, but also reduces the splicing gap and improves the appearance. At the same time, the back plate body 110 and the bent frame 120 are an integral structure, which is more stable than the ring structure composed of multiple frames, and can effectively avoid the problem of deformation during transportation, thereby reducing production costs. In this way, the back plate body 110 and the bent frame 120 are designed as an integral structure, which can not only consider the appearance of the appearance, but also reduce the number of parts to be assembled, simplify the assembly process, and reduce production costs.

[0071] In addition, the bent frame 120 not only constitutes the side surface of the interactive panel and the appearance surface of the front edge of the interactive panel along the first aspect, but also forms the installation groove 121 for installing the touch component 200, without the need for additional structures to install the touch component 200, further simplifying the assembly process and reducing production costs.

[0072] In one feasible implementation, a first planar segment 111 may be formed on the back panel body 110 near the bent frame 120. The first planar segment 111 is a planar structure that can be directly used to install and limit the internal components without the need for additional structures to achieve the flat installation requirement.

[0073] Regarding the specific structure of the 120-degree bent border, as follows: Figures 2 to 4 As shown, in one feasible implementation, the bent frame 120 can be L-shaped. Specifically, the bent frame 120 can include an outer segment 122 and a front segment 123. The outer segment 122 extends from the outer side of the first planar segment 111 in a direction perpendicular to the first planar segment 111 and away from the back panel body 110. The front segment 123 extends inward from the end of the outer segment 122 away from the first planar segment 111 in a direction parallel to the first planar segment 111, to ensure the flatness of the sides and front of the interactive flat panel. It is worth mentioning that the above-mentioned layout of the outer segment 122 and the front segment 123 can provide stronger structural support, especially at the corners of the outer segment 122 and the first planar segment 111 and the outer segment 122 and the front segment 123, which helps to improve the overall bending and torsional resistance. Furthermore, it can more effectively utilize the edge space of the interactive flat panel, providing sufficient installation space for internal components (such as the touch component 200) while maintaining a compact external size.

[0074] It should be noted that each component in the frame assembly 120 of this application has an inward and outward direction. The direction toward the center of the frame assembly 120 is "inward," and the direction away from the center of the frame assembly 120 is "outward." See details... Figure 2 The direction shown.

[0075] Of course, in some other feasible embodiments, the angle between the outer segment 122 and the first planar segment 111 is not a right angle, and there may be a certain angle between the front segment 123 and the first planar segment 111.

[0076] Because the end of the front section 123 furthest from the outer section 122 is the free end of the bent frame 120, and due to the overall thickness of the bent frame 120, the end of the front section 123 furthest from the outer section 122 has lower strength in actual production, making it prone to problems such as wavy deformation. To solve the above problems, such as Figure 2 and Figure 5As shown, in an implementable embodiment, the bent frame 120 can further include a reverse bending section 124. The reverse bending section 124 is located at an end of the front section 123 away from the outer section 122, and the reverse bending section 124 extends towards the back plate body 110. In this way, the reverse bending section 124 is arranged at the end of the front section 123 away from the outer section 122, and the structural rigidity of the front section 123 can be improved by the reverse bending section 124 and the corner of the front section 123, so that the deformation problem can be reduced without increasing the thickness of the bent frame 120.

[0077] Further, the touch component 200 is located between the reverse bending section 124 and the outer section 122, and the reverse bending section 124 and the outer section 122 can limit the inner and outer sides of the touch component 200, so as to provide better fixation and support for the touch component 200, and reduce displacement or deformation caused by external force.

[0078] The touch component 200 generally has a light transmission section 210, so that infrared light enters the inside of the touch component 200 through the light transmission section 210, or infrared light inside the touch component 200 is transmitted out through the light transmission section 210. The light transmission section 210 of the touch component 200 is provided with a matching groove 211 matched with the reverse bending section 124, so that the touch component 200 can be installed by referring to the matching groove 211 and the reverse bending section 124, which simplifies the installation process and enables the touch component 200 to be quickly and accurately installed in place. Moreover, the cooperation of the reverse bending section 124 and the matching groove 211 can also play a positioning role, so as to ensure the accuracy of the position of the touch component 200 installed in the installation groove 121, which helps to ensure the touch accuracy of the touch component 200 and avoid touch errors caused by improper installation.

[0079] As shown in FIGS. Figure 2 and Figure 5 As shown, in an implementable embodiment, when the reverse bending section 124 cooperates with the matching groove 211, the surface of the reverse bending section 124 and the light transmission section 210 can be substantially flush, so that the joint between the touch component 200 and the bent frame 120 is smoother and neater, and the appearance of the product is improved.

[0080] It should be noted that the reverse bending section 124 should not affect the transmission of the infrared light received and / or emitted by the touch component 200. In an implementable embodiment, the front end of the reverse bending section 124 extending towards the back plate body 110 does not exceed the receiving or emitting path of the touch signal of the touch component 200, that is, the infrared light received and / or emitted by the touch component 200 does not pass through the reverse bending section 124, so as to avoid the reverse bending section 124 affecting the transmission of the infrared light received and / or emitted by the touch component 200.

[0081] In another alternative embodiment, the front end of the reverse bending section 124 extending towards the back plate body 110 exceeds the receiving or transmitting path of the touch signal of the touch component 200, but the part of the reverse bending section 124 located on the receiving or transmitting path of the touch signal of the touch component 200 should be configured as a light-transmitting part, so that the infrared ray received and / or transmitted by the touch component 200 can be normally transmitted through the reverse bending section 124.

[0082] As shown in FIG. 1, in an implementable embodiment, the light-transmitting section 210 of the touch component 200 is arranged to be inclined towards the back plate body 110, that is, the light-transmitting section 210 of the touch component 200 is arranged to be non-perpendicular to the first planar section 111. Figure 2 and Figure 5 As shown in FIG. 1, in an implementable embodiment, the light-transmitting section 210 of the touch component 200 is arranged to be inclined towards the back plate body 110, that is, the light-transmitting section 210 of the touch component 200 is arranged to be non-perpendicular to the first planar section 111.

[0083] In another alternative embodiment, the light-transmitting section 210 of the touch component 200 is arranged to be substantially parallel to the outer section 122, that is, the light-transmitting section 210 of the touch component 200 is arranged to be substantially perpendicular to the first planar section 111. Correspondingly, the reverse bending section 124 is arranged to be substantially parallel to the outer section 122.

[0084] In order to facilitate the disassembly and assembly of the components in the mounting groove 121, as shown in FIG. 1, FIG. 2 and FIG. 3, in an implementable embodiment, the corner of the outer section 122 is provided with a clearance hole 125, which can extend to the adjacent two sides of the outer section 122 at the corner, so that the components in the mounting groove 121 can be installed into the mounting groove 121 through the clearance hole 125. Figure 4 、 Figure 6 and Figure 7 In order to facilitate the disassembly and assembly of the components in the mounting groove 121, as shown in FIG. 1, FIG. 2 and FIG. 3, in an implementable embodiment, the corner of the outer section 122 is provided with a clearance hole 125, which can extend to the adjacent two sides of the outer section 122 at the corner, so that the components in the mounting groove 121 can be installed into the mounting groove 121 through the clearance hole 125.

[0085] Further, the clearance hole 125 and the first planar section 111 are provided with a preset distance d. That is, the clearance hole 125 does not extend to the first planar section 111, so that the adjacent two sides of the outer section 122 have an integral connection part, thereby improving the structural rigidity of the outer section 122 and reducing the possibility of deformation of the outer section 122. The preset distance d can be set according to the experience value, and the value of the preset distance d should also be determined by referring to the size of the touch component 200 installed in the mounting groove 121, so as to prevent the touch component 200 installed in the mounting groove 121 from being unable to enter the mounting groove 121 through the clearance hole 125.

[0086] In practical applications, after the touch assembly 200 is inserted into the installation slot 121 through the positioning hole 125, a corner piece can be connected to the bent frame 120 at the positioning hole 125, and the corner piece covers the positioning hole 125, so that the outer surface of the bent frame 120 forms a complete surface to improve the appearance of the interactive panel. At the same time, the corner piece can also abut against the touch assembly 200 adjacent thereto to limit the movement of the touch assembly 200.

[0087] In practical applications, the interactive panel is usually configured in a rectangular structure, and accordingly, four side edges of the interactive panel are respectively provided with a frame to mount the touch assembly 200 and fix the edge of the internal components of the interactive panel. Among them, the four frames can be all composed of the above-mentioned bent frame 120, of course, the above-mentioned bent frame 120 can also only constitute part of the four frames.

[0088] As shown in Figure 6 and Figure 7 , in an implementable embodiment, the above-mentioned bent frame 120 usually has at least two frames, that is, at least two frames are integrally formed with the back plate body 110. The at least two frames are adjacently arranged so that the outer side section 122 of the bent frame 120 has a corner. The touch assembly 200 is mounted in each frame, and the projection of the touch assembly 200 in each frame along the length direction thereof is located in the positioning hole 125 at the end of the frame, so that the touch assembly 200 can be mounted into the installation slot 121 through the positioning hole 125.

[0089] Taking the example that the bent frame 120 constitutes three of the four frames, as shown in Figure 6 , the bent frame 120 includes a first frame 126, a second frame 127 and a third frame 128. The first frame 126 and the third frame 128 are located at two ends of the second frame 127, and the first frame 126 and the third frame 128 are parallel and oppositely arranged.

[0090] In practical applications, the second frame 127 can be one of the upper frame, the lower frame and the side frame of the interactive panel. It should be noted that the upper frame refers to the frame located at the uppermost position of the interactive panel when the interactive panel is in a use state, i.e., the interactive panel is vertically placed, the frame located at the lowermost position of the interactive panel is the lower frame, and the frame located at the side of the interactive panel is the side frame.

[0091] However, considering that the lower frame of the interactive panel often needs to additionally provide components such as interface ports, control buttons and indicator lights, and the structure is relatively complex, therefore, the second frame 127 is preferably adopted as the upper frame of the interactive panel, and accordingly, the first frame 126 and the third frame 128 are the two side frames of the interactive panel.

[0092] As to the specific way of integrally forming the back plate body 110 and the bending frame 120 by plastic deformation, in one realizable embodiment, the bending frame 120 and the back plate body 110 are stamped from the same plate material, the periphery of the plate material is first stretched by stamping to form a stretched wall perpendicular to the first planar section 111 and having a corner, and the remaining part of the plate material forms the back plate body 110. There is a relief hole near the edge of the stretched wall at the corner of the stretched wall, which is used for bending the periphery of the stretched wall and forming the relief hole 125. Then, the periphery of the stretched wall is bent inward, the part remaining in the original state forms the outer side section 122, and the part changing from the original state forms the front side section 123, that is, the edge of the stretched wall is bent inward to form the outer side section 122 and the front side section 123, and the relief hole 125 is formed at the corner of the outer side section 122, and the corners of the front side section 123 are engaged with each other. Correspondingly, the reverse folding section 124 is formed by again bending the edge of the front side section 123 toward the back plate body 110.

[0093] In actual application, the corner joint of the front side section 123 can be connected by laser welding or the like. Before the edge of the plate material is stretched by stamping to form the stretched wall, other features can also be formed by stamping and / or stamping and cutting, for example, some connecting hole positions are formed on the back plate body 110 and the bending frame 120, and a mounting groove is formed on the back plate body 110. Among them, the relief hole can be formed by stamping and cutting before the edge of the plate material is stretched by stamping to form the stretched wall, of course, the relief hole can also be formed by stamping and cutting after the stretched wall is formed.

[0094] In another alternative embodiment, the bending frame 120 can also be directly bent from the periphery of the back plate body 110.

[0095] Please also refer to Figure 2 and Figure 4 As shown, in one realizable embodiment, the interactive panel further comprises a module front frame 400 and a backlight module 500. The module front frame 400 has a base portion 410 and an inner extension portion 420, the base portion 410 is connected with the first planar section 111 to fix the module front frame 400 on the first planar section 111. The base portion 410 is partially located in the mounting groove 121, the base portion 410 and the outer side section 122 jointly form a limiting groove 411, the touch control assembly 200 is partially located in the limiting groove 411, and the base portion 410 and the outer side section 122 jointly limit the movement of the touch control assembly 200 to avoid the touch control assembly 200 from moving to affect the touch control accuracy.

[0096] In practical applications, the base portion 410 can be connected to the first planar segment 111 by screws. The screw can pass through the base portion 410 and connect to the first planar segment 111 from the side of the base portion 410 away from the first planar segment 111. However, considering that the base portion 410 is partially located within the mounting groove 121, if the above method is used, the screw-fastening tool is prone to bending the frame 120 during the screw-fastening process, causing interference and affecting the operation. Therefore, the screw can also pass through the first planar segment 111 and connect to the base portion 410 from the side of the first planar segment 111 away from the base portion 410.

[0097] The aforementioned inner extension 420 is located at the center of the inner side of the base portion 410 and extends inward in a direction parallel to the first planar segment 111. The backlight module 500 is confined between the inner extension 420 and the backplate body 110. In practical applications, the backlight module 500 may include a diffuser plate, an optical film, a light source, and a reflector. The diffuser plate is located between the optical film and the reflector. The optical film is located on the side of the diffuser plate closer to the protective panel 300. In use, the diffuser plate is used to scatter light from the light source to reduce brightness unevenness and visible light sources on the display screen. The optical film includes polarizers, etc., used to control the polarization direction of light. The reflector is used to reflect unscattered light, increasing light utilization and ensuring the effect of light source illumination.

[0098] It should be noted that each component in the front frame 400 of the module in this application has an inward and outward direction. The direction toward the center of the front frame 400 of the module is "inward", and the direction away from the center of the front frame 400 of the module is "outward".

[0099] Regarding the specific structure of the module front frame 400, in one feasible embodiment, the module front frame 400 can be a one-piece molded rectangular ring structure, and the module front frame 400 is installed as a whole. In another optional embodiment, the module front frame 400 is composed of four rods, which can be connected end to end to form a complete rectangular ring structure. In this way, the module front frame 400 can be disassembled into four rods for individual installation, allowing the module front frame 400 to be disassembled into four independent sections for individual installation, providing greater flexibility and suitable for installation scenarios with limited space, such as the mounting slot 121, to facilitate installation operations.

[0100] like Figures 2 to 10 As shown, in one feasible implementation, the interactive flat panel further includes a support member 600. The support member 600 has a connecting portion 610 and a supporting portion 620, wherein the connecting portion 610 is located on the side of the first planar segment 111 away from the bent edge 120, and the connecting portion 610 is connected to the first planar segment 111 to fix the support member 600 on the first planar segment 111.

[0101] The touch assembly 200 has a support section 220 for supporting the protective panel 300. The first planar section 111 is provided with a first through hole 112, the base portion 410 is provided with a second through hole 412 in communication with the first through hole 112, and the support portion 620 can abut the protective panel 300 in sequence through the first through hole 112 and the second through hole 412, so as to apply a force to the protective panel 300 in the direction of the support section 220, so as to press the protective panel 300 against the support section 220, and then fix the protective panel 300. At the same time, the force is transmitted from the protective panel 300 to the support section 220, and the touch assembly 200 is pressed against the front section 123, so as to fix the touch assembly 200. In this way, the protective panel 300 and the touch assembly 200 can be fixed at the same time by one support piece 600, so as to prevent the protective panel 300 and the touch assembly 200 from shaking, so as to simplify the installation structure and facilitate the installation operation. Compared with the way that the support piece 600 and the module front frame 400 are arranged side by side in the same plane in the related art, the support portion 620 of the support piece 600 of the present application abuts the touch assembly 200 through the module front frame 400, so that the overall structure is more compact, the space occupation is reduced, the width of the black border area on the interactive flat panel display side can be reduced, and a larger display area and better visual experience can be provided.

[0102] As shown in Figure 2 an implementable embodiment, the interactive flat panel further comprises a liquid crystal panel 700, which is a core component of the interactive flat panel and is responsible for displaying images and text. The liquid crystal panel 700 is attached to one side of the protective panel 300 adjacent to the back plate body 110, and the liquid crystal panel 700 can be installed into the back plate 100 together with the protective panel 300.

[0103] In actual application, double-sided tape 8 can be attached around the one side of the protective panel 300 adjacent to the back plate body 110, and the liquid crystal panel 700 is attached to the one side of the protective panel 300 adjacent to the back plate body 110 by the double-sided tape, so that the liquid crystal panel 700 is tightly attached to the protective panel 300, and the liquid crystal panel 700 and the protective panel 300 are almost zero-distance attached, so as to improve the visual display effect.

[0104] Further, the inner extension portion 420 is provided with a sealing piece 710 on the side away from the back plate body 110, and the sealing piece 710 abuts the liquid crystal panel 700, so as to seal the one side of the liquid crystal panel 700 adjacent to the back plate body 110 by the sealing piece 710, so as to prevent dust and other foreign matters from entering and affecting the visual display. In actual application, the sealing piece 710 can be made of foam, which is connected to the inner extension portion 420 by adhesion. Of course, the sealing piece 710 can also be made of other components with certain elastic function, such as rubber pad and elastic plastic.

[0105] In order to further understand the above-mentioned interactive panel, the application further provides an assembling method applied to the above-mentioned interactive panel, comprising the following steps:

[0106] S10, the backlight module 500 is loaded into the back plate 100 through the opening 130 of the back plate 100.

[0107] In the embodiment, the back plate 100 can be first adjusted to be placed with the opening 130 upward, so that the back plate 100 can support the backlight module 500 after the backlight module 500 is loaded into the back plate 100 through the opening 130 of the back plate 100, thereby facilitating the installation operation of the backlight module 500.

[0108] S20, the module front frame 400 is turned into the back plate 100 through the opening 130 and connected with the first plane section 111 of the back plate 100, so as to limit the backlight module 500 between the inner extension part 420 of the module front frame 400 and the back plate main body 110 of the back plate 100 by the module front frame 400.

[0109] In the embodiment, the module front frame 400 can be split into four sections of rods, allowing the module front frame 400 to be split into four independent sections for separate installation, thereby providing greater flexibility and being suitable for the installation scene of the limited space of the installation slot 121, so as to facilitate the installation operation.

[0110] S30, the liquid crystal panel 700 is adhered to the protection panel 300, the protection panel 300 with the liquid crystal panel 700 adhered thereto is loaded into the back plate 100 through the opening 130 at a certain angle and supported on the module front frame 400.

[0111] In the embodiment, the back surface of the protection panel 300 can be adhered with a ring of double-sided adhesive tape, and the liquid crystal panel 700 is adhered to the back surface of the protection panel 300 by the double-sided adhesive tape. Since the size of the protection panel 300 is slightly larger than the opening area of the opening 130, the protection panel 300 needs to be first inclined at a certain angle when installed, so that one end of the protection panel 300 is first installed into the back plate 100, and then the entire protection panel 300 is installed into the back plate 100. The module front frame 400 is used for temporary support of the protection panel 300 during installation.

[0112] S40, the touch assembly 200 is respectively inserted into the installation slot 121 of the first frame 126, the second frame 127 and the third frame 128 through the clearance hole 125, and a corner piece is installed at the clearance hole 125.

[0113] In the embodiment, the touch component 200 has four sections, two of which are used for emitting infrared rays and the other two of which are used for receiving infrared rays. The three sections of the touch component 200 are respectively inserted into the mounting slots 121 of the first frame 126, the second frame 127 and the third frame 128 through the insertion holes 125, and the remaining section of the touch component 200 is used for insertion into the lower frame. Among them, the touch component 200 mounted in the first frame 126 is one of the touch component 200 for emitting infrared rays and the touch component 200 for receiving infrared rays, and the touch component 200 mounted in the third frame 128 is the other of the touch component 200 for emitting infrared rays and the touch component 200 for receiving infrared rays.

[0114] S50, the support part 620 of the support 600 is sequentially abutted against the protection panel 300 and the module front frame 400 through the first planar section 111, so as to press the protection panel 300 against the touch component 200, press the touch component 200 against the front section 123, and connect the support 600 with the first planar section 111.

[0115] In the embodiment, the back plate 100 mounted with partial components can be first adjusted to be placed with the opening downward, so that the support 600 can be installed in a way of being inserted from top to bottom. Of course, the back plate 100 mounted with partial components can also be lifted to make the support 600 be installed in a way of being inserted from bottom to top.

[0116] S60, the lower frame is mounted on the back plate 100, so as to complete the assembly of the interactive panel.

[0117] Through the above assembly method, it can be verified from the side that the design of the interactive panel of the present application reduces the number of assembly components, thereby simplifying the overall assembly process. Moreover, the simplified assembly process reduces the assembly complexity, reduces the dependence on professional skills, makes the assembly process more intuitive and easy to operate, and thus improves the output speed of the production line and reduces the production cycle time. In addition, the simplified assembly process also helps to improve the consistency and reliability of product quality, because fewer components and steps reduce the chance of error. In summary, the structure of the interactive panel of the present application cooperates with the assembly method, optimizes the design and production process, and realizes the double improvement of cost efficiency and production efficiency.
