[0062] The related interactive tablet shell part is usually composed of a back plate and four frames mounted around the back plate. The frame and the back plate are connected by screws, and the adjacent two frames are connected by a corner piece and a decorative piece through screws. The interactive tablet shell part has many parts, and the back plate and the frame 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 interactive tablet shell part has multiple splicing areas, or in other words, multiple splicing gaps, which seriously affects the aesthetics of the interactive tablet.

[0063] In view of the above problems, the present inventors have attempted to integrally form multiple frames by roll forming, and then connect them 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 setting reduces some splicing gaps, but the gap between the frame and the back plate is still difficult to avoid. More importantly, the integrally formed frame surrounds the annular frame structure, which has poor stability. When subjected to external force, especially concentrated load or uneven load, it is easy to bend or twist, which is not convenient for material transportation.

[0064] 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 flanging structure can be formed by punching and stretching during the punching process, and then the frame 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.

[0065] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme 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 part of the embodiments of the present application, rather than all the embodiments.

[0066] 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 will be changed, thereby realizing 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.

[0067] Please refer to FIGS. 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 for supporting and protecting other components in the interactive panel. At the same time, the back plate 100 is wrapped on the outer surface of the interactive panel and used 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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, and 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.

[0072] 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.

[0073] In an implementable embodiment, the first planar section 111 can be formed adjacent to the bending frame 120 on the backboard body 110, and the first planar section 111 is a planar structure, which can be directly used for mounting and limiting the internal components, without the need for additional structures to achieve the flat mounting requirement.

[0074] Regarding the specific structure of the bending frame 120, as shown in FIGS. 2-4, in an implementable embodiment, the bending frame 120 can be provided in an L shape, specifically, the bending frame 120 can include an outer section 122 and a front section 123, the outer section 122 extends from the outer side of the first planar section 111 in a direction perpendicular to the first planar section 111 and away from the backboard body 110, and the front section 123 extends from the end of the outer section 122 away from the first planar section 111 in a direction parallel to the first planar section 111 and inwardly, so as to ensure the flatness of the side and front of the interactive panel. It is worth mentioning that the layout of the above-mentioned outer section 122 and front section 123 can provide stronger structural support, especially at the corner of the outer section 122 and the first planar section 111 and the corner of the outer section 122 and the front section 123, which helps to improve the overall bending and torsion resistance. Moreover, the edge space of the interactive panel can be more effectively utilized, providing sufficient mounting space for internal components (such as the touch component 200), while maintaining the compactness of the external dimensions.

[0075] It should be noted that the components in the frame assembly 120 in the present application have an inside-out direction, the direction towards the center of the frame assembly 120 is "inward", and the direction away from the center of the frame assembly 120 is "outward", which can be seen in the direction shown in FIG. 2.

[0076] Of course, in some other implementable embodiments, the angle between the outer section 122 and the first planar section 111 is not a straight angle, and there can be a certain angle between the front section 123 and the first planar section 111.

[0077] Since the end of the front section 123 away from the outer section 122 is the free end of the bending frame 120, and is limited by the overall thickness of the bending frame 120, in the actual production process, the end of the front section 123 away from the outer section 122 has low strength and is prone to wave deformation and other problems. To solve the above problems, as shown in FIGS. 2 and 5, in an implementable embodiment, the bending frame 120 can further include a reverse folding section 124. The reverse folding section 124 is located at the end of the front section 123 away from the outer section 122, and the reverse folding section 124 extends towards the backboard body 110. In this way, by providing the reverse folding section 124 at the end of the front section 123 away from the outer section 122, the structural rigidity of the front section 123 can be improved by using the corner of the reverse folding section 124 and the front section 123, thereby reducing the deformation problem without increasing the thickness of the bending frame 120.

[0078] Further, the touch component 200 is located between the reverse folding section 124 and the outer section 122, and the reverse folding 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.

[0079] 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 folding section 124, so that the touch component 200 can be installed in cooperation with the reverse folding section 124 by referring to the matching groove 211, thereby simplifying the installation process and enabling the touch component 200 to be quickly and accurately installed in place. In addition, the cooperation of the reverse folding section 124 and the matching groove 211 can also play a positioning role, so as to ensure the accuracy of the installation of the touch component 200 into the installation groove 121, which helps to ensure the touch accuracy of the touch component 200 and avoid touch errors caused by improper installation.

[0080] As shown in FIGS. 2 and 5, in an implementable embodiment, when the reverse folding section 124 cooperates with the matching groove 211, the surface of the reverse folding section 124 and the light transmission section 210 can be substantially flush, so that the joint of the touch component 200 and the bending frame 120 is smoother and neater, thereby improving the appearance of the product.

[0081] It should be noted that the reverse folding 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 folding 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 folding section 124, thereby avoiding the influence of the reverse folding section 124 on the transmission of the infrared light received and / or emitted by the touch component 200.

[0082] In another optional embodiment, the front end of the reverse folding section 124 extending towards the back plate body 110 exceeds the receiving or emitting path of the touch signal of the touch component 200, but the part of the reverse folding section 124 located on the receiving or emitting path of the touch signal of the touch component 200 should be configured as a light transmission component, so that the infrared light received and / or emitted by the touch component 200 can be normally transmitted through the reverse folding section 124.

[0083] As shown in FIG. 2 and FIG. 5, in an implementable embodiment, the light-transmitting segment 210 of the touch component 200 is arranged to be inclined away from the outer segment 122 while extending towards the backboard body 110, that is, the light-transmitting segment 210 of the touch component 200 is arranged to be non-perpendicular to the first planar segment 111. Correspondingly, the reverse bending segment 124 is arranged to be inclined away from the outer segment 122 while extending towards the backboard body 110.

[0084] In another optional embodiment, the light-transmitting segment 210 of the touch component 200 extends substantially parallel to the outer segment 122, that is, the light-transmitting segment 210 of the touch component 200 is arranged to be substantially perpendicular to the first planar segment 111. Correspondingly, the reverse bending segment 124 extends substantially parallel to the outer segment 122.

[0085] In order to facilitate the disassembly and assembly of the components in the installation groove 121, as shown in FIG. 4, FIG. 6 and FIG. 7, in an implementable embodiment, the corner of the outer segment 122 is provided with a clearance hole 125, which can extend to the adjacent two sides of the outer segment 122 at the corner, so that the components in the installation groove 121 can be installed into the installation groove 121 through the clearance hole 125.

[0086] Further, the clearance hole 125 and the first planar segment 111 have a preset distance d. That is, the clearance hole 125 does not extend to the first planar segment 111, so that the adjacent two sides of the outer segment 122 have a connected part, thereby improving the structural rigidity of the outer segment 122 and reducing the possibility of deformation of the outer segment 122. The preset distance d can be set according to the experience value, and the value of the preset distance d should also be referred to the size of the touch component 200 installed in the installation groove 121, so as to prevent the touch component 200 installed in the installation groove 121 from entering the installation groove 121 through the clearance hole 125.

[0087] In actual application, after the touch component 200 is inserted into the installation groove 121 through the clearance hole 125, the bending frame 120 at the clearance hole 125 can also be connected with a corner piece, and the corner piece covers the clearance hole 125, so that the outer surface of the bending frame 120 forms a complete surface, thereby improving the appearance of the interactive panel. At the same time, the corner piece can also abut against the adjacent touch component 200, so as to limit the movement of the touch component 200.

[0088] In actual application, the interactive panel is usually constructed as a rectangular structure, and correspondingly, the four sides of the interactive panel are respectively provided with a frame for installing the touch component 200 and fixing the edge of the internal components of the interactive panel. The four frames can be all composed of the above-mentioned bending frame 120, of course, the above-mentioned bending frame 120 can also only constitute part of the four frames.

[0089] As shown in FIG. 6 and FIG. 7, in an implementable embodiment, the above-mentioned bending frame 120 generally 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 bending frame 120 has a corner. The touch component 200 is mounted in each frame, and the projection of the touch component 200 in each frame along the length direction of the touch component 200 is located in the accommodation hole 125 at the end of the frame, so that the touch component 200 can be mounted into the mounting groove 121 through the accommodation hole 125.

[0090] Taking the bending frame 120 as an example of constituting three of the four frames, as shown in FIG. 6, the bending 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.

[0091] In actual application, the second frame 127 can be used as 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 use, that is, when 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.

[0092] However, considering that the lower frame of the interactive panel often needs to be additionally provided with components such as interface ports, control buttons and indicator lights, and the structure is relatively complex, therefore, the second frame 127 is preferably used as the upper frame of the interactive panel, and correspondingly, the first frame 126 and the third frame 128 are used as the two side frames of the interactive panel.

[0093] Regarding the specific way of integrally forming the back plate body 110 and the bending frame 120 by plastic deformation, in an implementable embodiment, the bending frame 120 and the back plate body 110 are processed by stamping from the same plate material. The periphery of the plate material is first stretched by stamping to form a stretching 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. The corner of the stretching wall is provided with an accommodation hole near the edge of the stretching wall, which is used for bending the periphery of the stretching wall and forming the accommodation hole 125. Then, the periphery of the stretching wall is bent inward, and 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 stretching wall is bent inward to form the outer side section 122 and the front side section 123, and the corner of the outer side section 122 forms the accommodation hole 125, and the corners of the front side section 123 are mutually engaged. Correspondingly, the reverse folding section 124 is formed by bending the edge of the front side section 123 again towards the back plate body 110.

[0094] 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 punched and stretched to form the stretched wall, other features can also be formed by punching and stretching and / or punching and cutting, for example, some connecting hole positions are formed on the back plate body 110 and the bent frame 120, and a mounting groove is formed on the back plate body 110. Among them, the avoidance hole can be formed by punching and cutting before the edge of the plate material is punched and stretched to form the stretched wall, of course, the avoidance hole can also be formed by punching and cutting after the stretched wall is formed.

[0095] In another optional embodiment, the bent frame 120 can also be directly bent from the periphery of the back plate body 110.

[0096] Please also refer to FIGS. 2 and 4, in an implementable embodiment, the interactive tablet further comprises a module front frame 400 and a backlight module 500. The module front frame 400 has a base part 410 and an inner extension part 420, the base part 410 is connected with the first plane section 111 to fix the module front frame 400 on the first plane section 111. The base part 410 is partially located in the mounting groove 121, the base part 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, the base part 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.

[0097] In actual application, the base part 410 can be connected with the first plane section 111 by a screw. The screw can pass through the base part 410 from the side of the base part 410 away from the first plane section 111 and be connected with the first plane section 111. However, considering that the base part 410 is partially located in the mounting groove 121, if the above-mentioned mode is adopted, the locking tool is easy to interfere with the bent frame 120 during the locking process, thus, the screw can also pass through the first plane section 111 from the side of the first plane section 111 away from the base part 410 and be connected with the base part 410.

[0098] The above-mentioned inner extension part 420 is located in the middle of the inner side of the base part 410 and extends inwardly along the direction parallel to the first plane section 111, and the backlight module 500 is limited between the inner extension part 420 and the back plate body 110. In actual application, the backlight module 500 can include a diffusion plate, an optical film, a light source and a reflecting sheet, the diffusion plate is located between the optical film and the reflecting sheet, the optical film is located on the side of the diffusion plate close to the protective panel 300, and during use, the diffusion plate is used to scatter the light from the light source to reduce the brightness unevenness and visible light source on the display screen. The optical film includes a polarizing sheet and the like, which is used to control the polarization direction of the light. The reflecting sheet is used to reflect the light that is not scattered to increase the utilization rate of the light and can ensure the illumination effect of the light source.

[0099] It should be noted that the components in the module front frame 400 have an inside and outside direction, the direction towards the center of the module front frame 400 is "inside", and the direction away from the center of the module front frame 400 is "outside".

[0100] Regarding the specific structure of the module front frame 400, in one implementable embodiment, the module front frame 400 can be an integrally formed rectangular ring structure, and the module front frame 400 is installed in one body. In another alternative embodiment, the module front frame 400 is composed of four rod pieces, which can be connected end to end to form a complete rectangular ring structure. In this way, the module front frame 400 can be split into four separate rod pieces for separate installation, allowing the module front frame 400 to be split into four independent sections for separate installation, providing greater flexibility and being suitable for installation scenarios such as the space-limited installation slot 121 to facilitate installation operations.

[0101] As shown in FIGS. 2-10, in one implementable embodiment, the interactive panel further includes a support piece 600. The support piece 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 section 111 away from the bent frame 120, and the connecting portion 610 is connected to the first planar section 111 to fix the support piece 600 on the first planar section 111.

[0102] The touch assembly 200 has a supporting section 220 for supporting the protective panel 300. The first planar section 111 is provided with a first through hole 112, and the base portion 410 is provided with a second through hole 412 in communication with the first through hole 112. The supporting portion 620 can pass through the first through hole 112 and the second through hole 412 in sequence and abut against the protective panel 300, thereby applying a force to the protective panel 300 in the direction of the supporting section 220 to press the protective panel 300 against the supporting section 220 and thereby fix the protective panel 300. At the same time, the force is transmitted from the protective panel 300 to the supporting section 220 and presses the touch assembly 200 against the front side section 123, thereby fixing the touch assembly 200. In this way, the support piece 600 can simultaneously fix the protective panel 300 and the touch assembly 200, preventing the protective panel 300 and the touch assembly 200 from shaking, thereby simplifying the installation structure and facilitating installation operations. Compared with the related art in which the support piece 600 and the module front frame 400 are arranged side by side in the same plane, the supporting portion 620 of the support piece 600 of the present application abuts against the touch assembly 200 through the module front frame 400, making the overall structure more compact and reducing the space occupation, thereby reducing the width of the black border area on the display side of the interactive panel and providing a larger display area and better visual experience.

[0103] As shown in FIG. 2, in an implementable embodiment, the interactive panel further comprises a liquid crystal panel 700, which is a core component of the interactive 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.

[0104] In actual application, double-sided tape 8 can be attached to the periphery of one side of the protective panel 300 adjacent to the back plate body 110, and the liquid crystal panel 700 is attached to 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, thereby improving the visual display effect.

[0105] Further, the inner extension part 420 is provided with a sealing member 710 on the side away from the back plate body 110, and the sealing member 710 abuts against the liquid crystal panel 700, so that the sealing member 710 seals the periphery of one side of the liquid crystal panel 700 adjacent to the back plate body 110, thereby preventing dust and other foreign matters from entering and affecting visual display. In actual application, the sealing member 710 can be made of foam, which is connected to the inner extension part 420 by adhesion. Of course, the sealing member 710 can also be made of other components having certain elastic function, such as rubber pad and elastic plastic.

[0106] In order to further understand the above-described interactive panel, the application further provides an assembly method applied to the above-described interactive panel, which comprises the following steps:

[0110] In the embodiment, the module front frame 400 can be split into four rod parts, allowing the module front frame 400 to be split into four independent parts for separate installation, thereby providing greater flexibility and being suitable for installation scenes with limited space such as the installation slot 121, so as to facilitate the installation operation.

[0111] S30, adhering the liquid crystal panel 700 to the protective panel 300, loading the protective panel 300 with the adhered liquid crystal panel 700 into the back plate 100 through the opening 130 at an angle, and supporting the protective panel 300 on the module front frame 400.

[0116] In the embodiment, the back plate 100 with the installed partial components can be adjusted to be placed with the opening facing downward, so that the support piece 600 can be installed in a downward insertion manner from above. Of course, the back plate 100 with the installed partial components can also be raised, so that the support piece 600 can be installed in an upward insertion manner from below.

[0117] S60, install the lower frame to the back plate 100, thereby completing the assembly of the interactive tablet.
