Description

Interactive panel, frame assembly and touch control assembly TECHNICAL FIELD

[0001] The present application relates to the field of display devices, in particular to an interactive panel, a frame assembly and a touch control assembly. BACKGROUND

[0002] In the existing interactive panel, a quadrilateral frame assembly is generally formed by four touch frames connected in sequence end to end, and a touch circuit board in the frame assembly needs to be extended to the corner of the quadrilateral frame assembly to ensure the touch signal quality at the corner.

[0003] However, this results in interference between two adjacent touch frames during assembly of the touch control assembly, so that the assembler needs to disassemble one side of the touch frame in advance, and then reassemble the touch frame after the assembly of the touch control assembly in the remaining touch frames is completed, which is complicated and costly, and the repeated disassembly and assembly of the frame assembly can cause the touch control assembly to shift, resulting in inaccurate touch control and reduced user experience.

[0004] SUMMARY

[0005] The present application aims to provide an interactive panel, a frame assembly and a touch control assembly, which can realize the assembly of the touch control assembly without disassembling the frame assembly.

[0007] The technical scheme provided in the application can realize the limiting of the touch control circuit board through the abutting of one end of the touch control circuit board and the limiting part and the abutting of the limiting part on one side of the pressing block close to the limiting part connected with the touch control circuit board. Compared with the existing limiting mode in which the two ends of the touch control circuit board abut against the limiting parts at the two ends of the side frame, the other end of the side frame does not need to be provided with a limiting part in the scheme, thereby leaving a space for giving way, so that the other end of the touch control circuit board in the touch control assembly can be inserted into the space for giving way obliquely, and then the touch control assembly can be installed in the side frame by rotating the touch control assembly as a whole to one side of the side frame, thereby realizing the assembly of the touch control assembly without disassembling the frame assembly, improving the assembly efficiency, reducing the defective rate, and avoiding the displacement of the touch control assembly 200 in the frame assembly due to multiple disassembly and assembly, which affects the touch control accuracy, improves the touch control accuracy, and further optimizes the user experience. Meanwhile, the assembly hole is formed on the side surface of the light filtering strip, which can facilitate the worker to adjust and move the touch control circuit board to one end of the limiting part through the assembly hole when the touch control assembly is installed in the side frame by rotating the touch control assembly as a whole to one side of the side frame, thereby facilitating the user operation.

[0008] Optionally, the assembly hole is configured as a rectangular hole, and the rectangular hole extends along the length direction of the light filtering strip; the length of the assembly hole is greater than the length of the limiting part, and / or the width of the assembly hole is greater than the width of the limiting part.

[0009] Through the above scheme, the inner contour of the assembly hole is slightly larger than the outer contour of the limiting part, so as to facilitate the operator to connect the limiting part with the touch control circuit board through the assembly hole. When the limiting part is connected with the touch control circuit board through the rectangular hole, the connection length of the limiting part and the touch control circuit board in the stress direction of the limiting part can be increased, so as to reduce the local stress concentration of the limiting part and the touch control circuit board, and improve the stability and carrying capacity of the connection between the limiting part and the touch control circuit board.

This dual-function design does not need to increase additional components, significantly reducing the production cost. Meanwhile, the part of the light filtering strip for filtering light and the part for opening the assembly hole are located on different surfaces, thereby avoiding that the limiting piece blocks infrared rays when the limiting piece is installed in the assembly hole.

[0012] Optionally, the limiting piece is pasted to the touch circuit board, and the limiting piece is foam.

[0013] Through the above scheme, the staff only needs to pass the limiting piece through the assembly hole and press it towards the side of the touch circuit board to realize the connection, which is simple to operate and convenient for installation.

[0014] Optionally, the touch frame is a side frame; the interactive panel further comprises an upper frame and a lower frame; the side frame has two, and the two side frames are oppositely arranged; the upper frame and the lower frame are oppositely arranged; and the upper frame, the lower frame and the two side frames surround to form a rectangular ring structure.

[0023] The application provides a technical scheme, which can limit the touch circuit board by abutting one end of the touch circuit board with the limiting part and abutting the limiting piece connected with the touch circuit board with the side of the assembly hole away from the limiting part. Compared with the existing limiting mode of abutting two ends of the touch circuit board with the limiting parts at two ends of the side frame, respectively, the other end of the side frame in the application does not need to be provided with a limiting part, so that a space is left for the other end of the touch circuit board in the touch assembly to be inserted obliquely into the space, and then the touch assembly is installed in the side frame by rotating the touch assembly to one side of the side frame, so that the touch assembly can be assembled without disassembling the frame assembly, the assembly efficiency is improved, and the defective rate is reduced.

DETAILED DESCRIPTION

[0042] For the purpose of making the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be described in further detail below with reference to the drawings. The terms for indicating spatial relative positions such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" and the like used in the present application are for the purpose of conveniently describing the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The terms for indicating spatial relative positions can be intended to include different orientations of the device in use or in operation in addition to the orientation shown in the drawings. For example, if the device in the drawings is turned over, the unit described as being "below" or "under" the other unit or feature will be "above" the other unit or feature. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially-related descriptions used herein are interpreted accordingly.

[0043] In addition, the terms "mounting", "arranging", "provided with", "connecting", "slidingly connecting", "fixing", and "sleeving" should be interpreted in a broad sense. For example, "connecting" can be fixed connection, detachable connection, or integral configuration; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection via an intermediate medium, or internal communication between two devices, elements, or components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present application according to specific circumstances.

[0044] An interactive panel is a device with touch screen technology, and a user can interact with it through a finger or a special stylus. Common interactive panels usually have resistive touch screens, capacitive touch screens, and infrared technology touch screens. Taking an infrared technology touch screen as an example, the infrared technology touch screen is an interactive screen composed of infrared emission and receiving sensing elements installed on the frame of the touch screen. On the surface of the screen, an infrared detection network is formed, and any touching object can change the infrared on the touch point to realize touch screen operation.

[0045] The existing infrared technology touch screen generally has a quadrilateral frame assembly formed by four touch frames connected in sequence in a head-to-tail manner. The touch circuit board in the frame assembly usually needs to extend to the corner of the quadrilateral frame assembly to ensure the touch signal quality at the corner.

[0046] For example, the length of the touch circuit board of the touch component in the left and right frames is greater than the length of the light filtering strip, and the touch circuit board of the touch component in the left and right frames is limited by abutting against the limiting part at both ends of the frame, and the two ends of the touch circuit board extend out of the two ends of the light filtering strip, thereby extending to the corner of the touch screen, and further ensuring the touch signal quality at the corner. However, during assembly, the length of the touch component in the left and right frames is much greater than the distance between the touch components in the upper and lower frames, and is blocked by the limiting part at both ends of the frame, so that the touch component cannot be installed in the corresponding frame in a diagonal insertion manner. In this way, the touch components in the left and right frames interfere with the touch components in the upper and lower frames during assembly, and the assembly operation cannot be completed.

[0047] The existing method is that an operator disassembles the lower frame of the frame assembly (generally, the frame assembly is integrally shipped) that is originally assembled together, then assembles the touch components of the upper frame and the left and right frames, wherein the two ends of the touch circuit board in the left and right frames abut against the limiting part at both ends of the frame, and finally assembles the touch component of the lower frame and re-installs the assembled lower frame back to the original position.

[0048] Obviously, the above-mentioned manner needs to disassemble and reassemble the lower frame additionally, the process is complicated, and the disassembly and assembly of the lower frame is difficult to control, and the gap is prone to increase, and other problems occur, and the touch assembly inside the frame assembly is prone to shift, that is, the touch sensing position is offset, thereby causing inaccurate touch and low user experience. In addition, since the lower frame is a long strip structure, one person cannot ensure that both ends are assembled in place during assembly, and the filter strip may be detached. In addition, when assembling the lower frame and the left and right frames, it is necessary to move the frame to adjust the assembly gap, which cannot be completed by one person, which requires multiple people to cooperate and operate, and the labor demand is large, and the manufacturing cost is high.

[0049] To solve the problem of disassembling the frame to complete the assembly, the present inventors have attempted to make the limiting portion of one end of the left and right frames into a detachable structure. Taking the left frame as an example, during assembly, the limiting portion of one end of the left frame is disassembled, and then a space is left to allow the touch assembly of the left frame to be installed in the left frame by means of oblique insertion and then rotation, so that the lower frame does not need to be disassembled. Although it does not need to disassemble the lower frame, it still needs to disassemble the limiting portion and install it back after assembly, which also affects production efficiency. Moreover, when the touch assembly of the left frame is installed in the left frame, the gap between the touch assembly and one end of the left frame is too small, and it is not convenient for the worker to adjust the position of the touch circuit board in the left frame so that the touch circuit board can be moved to abut against the limiting portion of the other end, thereby leaving the installation position of the disassembled limiting portion, which is not convenient to operate.

[0050] Therefore, the present application changes the limiting method of the touch circuit board in the touch assembly of the existing left and right frames (side frames), specifically, the touch circuit board is limited by abutting against the limiting portion at one end of the touch circuit board and by the abutment between the limiting piece connected to the side surface of the touch circuit board and the pressing block. Compared with the existing method of limiting the touch circuit board by abutting against the limiting portions at both ends of the touch circuit board and the side frames, the other end of the side frame does not need to be provided with a limiting portion in the scheme adopted by the present application, thereby leaving a space for the other end of the touch assembly to be obliquely inserted into the space and then rotated to the side of the side frame, so that the touch assembly can be installed in the side frame without disassembling the frame assembly. In this way, the operator can assemble the touch assembly without disassembling the frame assembly, avoid the position of the touch assembly installed in the frame assembly from being offset due to multiple disassembly and assembly, and improve the touch accuracy and user experience. At the same time, since the side surface of the filter strip is provided with an assembly hole, when the touch assembly is installed in the side frame by rotating the whole touch assembly to the side of the side frame, the operator can pass through the assembly hole to adjust and move the touch circuit board to the end of the limiting portion so that one end of the touch circuit board abuts against the limiting portion, which is convenient for the user to operate.

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the embodiments described in the present application are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0052] The present application provides an interactive panel which integrates infrared touch control and display functions. Specifically, the infrared touch control function is realized by infrared emission and receiving sensing elements installed on the frame of the interactive panel. These elements form an infrared detection network on the screen surface, and when any touch object contacts the screen, the infrared on the touch point can 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, man-machine interactive panels, televisions and smart blackboards.

[0053] Please refer to FIGS. 1 to 4, in an implementable embodiment, the interactive panel can at least include a touch frame. The touch frame has a containing groove 110 and a limiting part 120, and the limiting part 120 is located at one end of the containing groove 110. In the present embodiment, the containing groove 110 should be arranged along the length direction of the touch frame, and the containing groove 110 has an opening so that the parts contained in the containing groove 110 can be installed into the containing groove 110 through the opening, and the parts contained in the containing groove 110 can cover the entire length direction of the touch frame as much as possible. The limiting part 120 is used to abut against the parts contained in the containing groove 110, thereby limiting the parts in the containing groove 110.

[0054] In actual application, the touch frame serves as a supporting part, mainly used for supporting and protecting the parts or components inside it. The limiting part 120 can be integrally formed with the touch frame by bending or other methods, of course, it can also be designed separately and then connected to the touch frame, which is not limited in the present application.

[0055] It should be noted that the above-mentioned touch frame can be used as at least one of the left frame, the right frame, the upper frame and the lower frame of the interactive panel, which is not limited here.

[0056] The above-mentioned interactive tablet can further comprise a touch component 200 for realizing infrared touch sensing. The touch component 200 can comprise a light filtering strip 210, a touch circuit board 220 and a limiting member 230. The light filtering strip 210 is embedded in the accommodating groove 110 and extends along the length direction of the accommodating groove 110. The light filtering strip 210 has a mounting cavity 211 and an assembly hole 212. The mounting cavity 211 penetrates through the opposite ends of the light filtering strip 210 so that the end portions thereof are open. The touch circuit board 220 can be mounted in the mounting cavity 211 through the opening of one end thereof. The touch circuit board 220 can slide along the length direction of the mounting cavity 211 and can extend out of the openings of the two ends. The assembly hole 212 is located on the side surface of the light filtering strip 210 and communicates with the mounting cavity 211. The assembly hole 212 is used for adjusting the position of the touch circuit board 220 in the mounting cavity 211 by an operator and providing a space for the limiting member 230 to connect the touch circuit board 220 through the light filtering strip 210.

[0057] In actual application, the light filtering strip 210 is usually made of a material with good infrared transmission performance, such as infrared transparent plastic or glass material, so that the light filtering strip 210 can filter out visible light and only allow infrared light to pass through, thereby ensuring the normal operation of the infrared touch technology. The touch circuit board 220 generally comprises a PCB board and an infrared receiver and / or an infrared emitter. The infrared receiver and / or the infrared emitter are electrically connected to the PCB board and face the light emitting part of the light filtering strip 210. When the touch circuit board 220 contains the infrared emitter, the infrared rays emitted by the infrared emitter can pass through the light filtering strip 210 and be shot to the corresponding receiving component (in the other side frame structure) arranged thereon, so that the infrared rays penetrate the light filtering strip 210 of the corresponding receiving component and are received by the infrared receiver of the receiving component. When a user operates on the display surface of the interactive tablet, the user blocks the infrared rays emitted by the infrared emitter, and the receiving component cannot receive the infrared rays emitted by the emitting component. The interactive tablet can perform signal positioning on the input signal according to the change of the signal.

[0058] The above-mentioned interactive tablet can further comprise a pressing block 300. The pressing block 300 is connected to the touch frame. When one end of the touch circuit board 220 abuts against the limiting portion 120, the limiting member 230 is connected to the touch circuit board 220 through the assembly hole 212. The limiting member 230 is located between the pressing block 300 and the limiting portion 120 and abuts against the side of the pressing block 300 close to the limiting portion 120, thereby limiting the freedom degree of movement of the touch circuit board 220 along the length direction of the touch frame.

[0059] It is worth mentioning that, compared with the prior art, the touch circuit board 220 is limited by abutting with the limiting part 120 at one end and the limiting part 230 connected with the side of the touch circuit board 220 abutting with the pressing block 300, which changes the limiting mode of the touch circuit board 220, so that the other end of the touch frame does not need to be provided with the limiting part 120, leaving a space a. In this way, as shown in FIGS. 5 and 6, the other end of the touch assembly 200 can be inserted into the space a, and then the touch assembly 200 is installed in the touch frame by rotating the whole to one side of the touch frame (the direction of the arrow in FIG. 5), and then the touch assembly 200 can be assembled into the accommodating groove 110 without disassembling the frame assembly. In this way, the operator can assemble the touch assembly 200 without disassembling the frame assembly, thereby avoiding the displacement of the touch assembly 200 in the frame assembly due to multiple disassembly and assembly, affecting the touch precision, improving the touch accuracy, and optimizing the user experience. When the touch assembly 200 is damaged, the operator can first remove the limiting part 230, then move the touch circuit board 220 away from the limiting part 120, and finally remove it from the touch frame by rotating away from the touch frame, so that the disassembly of the touch assembly 200 becomes convenient and fast, and no longer needs to go through a complex disassembly process to disassemble the frame assembly, saving the time required for maintenance, maintenance and replacement of parts, and saving labor costs.

[0060] At the same time, since the assembly hole 212 is provided on the side of the light filtering strip 210, when the touch assembly 200 is installed in the touch frame by rotating the whole to one side of the touch frame, the operator can adjust and move the touch circuit board 220 to one end of the limiting part 120 through the assembly hole 212, so that one end of the touch circuit board 220 abuts with the limiting part 120, which is convenient for user operation and improves the assembly efficiency.

[0061] The above assembly hole 212 can be constructed as a hole with any shape, such as a circular hole, a rectangular hole, or a triangular hole.

[0062] For example, the assembly hole 212 is configured as a rectangular hole, in an embodiment, the rectangular hole should extend along the length direction of the light filtering strip 210, so that when the limiting member 230 is connected with the touch circuit board 220 through the rectangular hole, the connection length of the limiting member 230 and the touch circuit board 220 in the force direction of the limiting member 230 can be increased, thereby reducing the local stress concentration of the limiting member 230 and the touch circuit board 220, and improving the stability and carrying capacity of the connection between the two. The length of the assembly hole 212 should be greater than the length of the limiting member 230, and / or the width of the assembly hole 212 should be greater than the width of the limiting member 230, so that the inner contour of the assembly hole 212 is slightly larger than the outer contour of the limiting member 230, to facilitate the operator to connect the limiting member 230 with the touch circuit board 220 through the assembly hole 212.

[0063] The above-mentioned pressing block 300 can be used alone as a component for limiting the movement of the limiting member 230 away from the limiting portion 120.

[0064] Of course, the above-mentioned pressing block 300 can also serve as a clamping component. For a clear display of its function, please refer to FIGS. 7-9, in an embodiment, the interactive panel further comprises a clamped member 400. The light filtering strip 210 has a support surface 213, and the clamped member 400 is located between the support surface 213 and the pressing block 300, and the support surface 213 and the pressing block 300 are used together to clamp the clamped member 400. Through this design, the pressing block 300 not only effectively prevents the limiting member 230 from moving away from the limiting portion 120, but also cooperates with the light filtering strip 210 to achieve the fastening of the clamped member 400. This dual-function design does not require additional components, significantly reducing production costs.

[0065] In this embodiment, the clamped member 400 serves as a protective component on the display side of the interactive panel, preventing damage to the display module of the interactive panel, and the clamped member 400 can be made of glass or transparent plastic material, etc. In actual application, the pressing block 300 should be detachably connected with the touch frame, so that when the touch component 200 and the clamped member 400 are installed, the pressing block 300 can be avoided to avoid interference between the pressing block 300 and the installation path of the touch component 200 and the clamped member 400. In order to ensure the clamping stability of the clamped member 400, the pressing block 300 should have multiple, and the multiple pressing blocks 300 are arranged along the length direction of the touch frame, and correspondingly, the limiting member 230 abuts against one of the touch frames.

[0066] In view of the infrared rays to be emitted or entered through one side of the light filtering strip 210, in order to avoid the assembly hole 212 from affecting the infrared rays, please refer to Figs. 7-9 again, in an implementable embodiment, the light filtering strip 210 further has a light filtering surface 214 and a blocking surface 215. The supporting surface 213 is located between the light filtering surface 214 and the blocking surface 215, the light filtering surface 214 is used for filtering the light emitted or received by the touch circuit board, and the assembly hole 212 is formed on the blocking surface 215. In other words, the part of the light filtering strip 210 used for filtering the light and the part used for forming the assembly hole 212 are located on different surfaces respectively, so as to avoid the limiting part 230 from blocking the infrared rays when the limiting part 230 is installed in the assembly hole 212, and improve the touch accuracy.

[0067] In actual application, the light filtering surface 214, the supporting surface 213 and the blocking surface 215 are integrally formed by the light filtering strip 210 during injection extrusion, the light filtering surface 214 and the supporting surface 213 are formed by the part of the light filtering strip 210 extending inward, the light filtering surface 214 corresponds to the infrared emitter and / or the infrared receiver on the touch circuit board 220, so that the emitted or received infrared rays can be transmitted after passing through the light filtering surface 214.

[0068] Please refer to Fig. 7, in an implementable embodiment, the inner wall of the mounting cavity 211 is formed with a sliding groove 216. The sliding groove 216 extends along the length direction of the mounting cavity 211, the touch circuit board 220 is clamped in the sliding groove 216, so as to limit the touch circuit board 220 from sliding along the length direction of the mounting cavity 220 by the sliding groove 216, thereby limiting the sliding direction of the touch circuit board 220, and the limiting part 120 is located on the sliding direction of the touch circuit board 220, so that the touch circuit board 220 sliding along the sliding groove 216 can necessarily abut against the limiting part 120 located at one end of the mounting cavity 220. At the same time, the sliding groove 216 can also make the touch circuit board 220 always in a vertical state, preventing the touch circuit board 220 from deviating during sliding, thereby ensuring the touch accuracy of the interactive panel and improving the interactive experience.

[0069] In the embodiment, the sliding groove 216 can have two, the two sliding grooves 216 are located on the top surface and the bottom surface of the mounting cavity 220 and oppositely arranged, and the touch circuit board 220 stably slides under the limitation of the two sliding grooves 216. In actual application, the sliding groove 216 can be a groove structure recessed outward on the inner wall of the mounting cavity 220. Of course, the sliding groove 216 can also be formed by two protrusions protruding inward on the inner wall of the mounting cavity 220, which is not limited in the present application.

[0070] In an implementable embodiment, the limiting member 230 is pasted to the touch circuit board 220. During installation, the operator only needs to pass the limiting member 230 through the assembly hole 212 and press it towards the side of the touch circuit board 220 to achieve the connection, which is simple to operate and convenient for installation. Of course, the limiting member 230 can also be connected to the touch circuit board 220 in other ways, for example, the touch circuit board 220 is provided with buckles or card slots, and the limiting member 230 is connected to the touch circuit board 220 by buckling or card slot connection, etc. The application does not make specific limitations here.

[0071] In actual application, the limiting member 230 should have a certain hardness to avoid deformation and movement of the limiting member 230 when the limiting member 230 abuts against the pressing block 300. The limiting member 230 can be made of foam, rubber block or plastic block, etc.

[0072] The overall structure of the interactive panel is usually composed of a display module and a frame assembly, the frame assembly surrounds the outer edge of the display module and is matched with the outer extension shape of the display module. The frame assembly is usually composed of multiple frames connected in sequence and enclosed. The above-mentioned touch frame is one of the frames of the frame assembly, and each frame is matched with the side edge of the corresponding display module. Specifically, the length of each frame is slightly longer or shorter than the length of the side edge of the corresponding display module. When each frame is slightly shorter than the corresponding side edge, the adjacent two frames can be connected through a connecting component such as a corner piece. When each frame is slightly longer than the corresponding side edge, the adjacent two frames can be formed into an integrated structure through welding or through a piece of sheet metal directly rolled, bent, etc.

[0073] In general, the orthographic projection shape of the display module on the front surface can be a quadrilateral, and of course it is not limited to other shapes. Correspondingly, the shape enclosed by the frame assembly can also be a quadrilateral or other shape ring structure. Among them, the front surface defined by the application refers to the side of the interactive panel facing the user in the use state, and vice versa.

[0074] Taking the frame assembly enclosing a quadrilateral ring structure as an example, the frame assembly is arranged around the outer periphery of the display module in a single-section structure, an integrated structure or at least a partially integrated structure. Specifically, please refer to Fig. 1 again. In an implementable embodiment, the above-mentioned touch frame is used as a side frame 100. The interactive panel further comprises an upper frame 500 and a lower frame 600. The side frame 100 has two, and the two side frames 100 are oppositely arranged. The upper frame 500 and the lower frame 600 are oppositely arranged, and the upper frame 500, the lower frame 600 and the two side frames form a quadrilateral ring structure.

[0075] In the embodiment, the interactive panel is taken as an example in the perspective of FIG. 1. The upper frame 500 is located above the interactive panel, the lower frame 600 is located below the interactive panel, and the two side frames 100 are respectively located on the left and right sides of the interactive panel. Preferably, the quadrilateral ring structure enclosed by the frame assembly is a rectangular ring structure. It should be noted that the rectangular ring structure enclosed by the frame assembly can effectively fix each part of the interactive panel, provide better structural support and stability, and prevent the interactive panel from shaking or deforming during use. In addition, the interactive panel formed by such a setting is of a rectangular structure, which is beneficial to the aesthetic appearance of the overall appearance. Subsequently, the frame assembly will also be described as a rectangular ring structure.

[0076] In actual application, the two side frames 100 are respectively provided with touch components 200. One of the touch circuit boards 220 in the side frame 100 is used to emit infrared signals, and the other touch circuit board 220 in the side frame 100 is used to receive infrared signals, so as to form an infrared detection network in the X direction on the screen surface. Similarly, the upper frame 500 and the lower frame 600 are also respectively provided with touch components, and one of them is used to emit infrared signals, and the other is used to receive infrared signals, so as to form an infrared detection network in the Y direction on the screen surface.

[0077] In order to facilitate the operator to adjust the side touch frame 220 through the operation hole 212 when the side light filtering component 200 is installed in the accommodating groove 110, please refer to FIG. 3 again. In an implementable embodiment, the rectangular ring structure has an inner side and an outer side. The opening of the accommodating groove 110 faces the inner side, the side light filtering strip 210 is embedded in the accommodating groove 110 through the opening, and the operation hole 212 is located on the side of the side light filtering strip 210 close to the inner side. In this way, when the side light filtering strip 210 is installed in the accommodating groove 110, the operation hole 212 can be exposed from the opening, so that the side touch frame 220 inside the side light filtering strip 210 can be adjusted without taking out the side light filtering strip 210.

[0078] The limiting part 120 can be located at one end of the accommodating groove 110 close to the lower frame 600, or at one end of the accommodating groove 110 close to the upper frame 500.

[0079] But in view of the fact that the interactive tablet is in a vertical state in most cases, this also makes the components in the interactive tablet have a force towards the side of the lower frame 600 under the action of gravity most of the time. In this way, if the limiting part 120 is located at one end of the accommodating groove 110 close to the upper frame 500, when the interactive tablet is in a vertical state, the limiting part 120 is located above the touch circuit board 220, and the limiting part 120 does not support the touch circuit board 220, and the gravity of the touch circuit board 220 is mainly concentrated at the bonding part of the limiting part 230 and the touch circuit board 220, which requires a greater bonding force for the bonding part. In the long run, this will inevitably cause the limiting part 230 to be separated from the touch circuit board 220, thereby causing the touch circuit board 220 to move downward.

[0080] To solve the above problem, the limiting part 120 is preferably located at one end of the accommodating groove 110 close to the lower frame 600, so that when the interactive tablet is in a vertical state, the limiting part 120 is located below the touch circuit board 220, and the gravity of the touch circuit board 220 is mainly concentrated on the limiting part 120. In this way, the possibility of the bonding part of the limiting part 230 and the touch circuit board 220 being separated and causing the touch circuit board 220 to be displaced is reduced, the accuracy of the touch signal position of the interactive tablet is ensured, and the product quality is improved.

[0081] In actual application, the limiting part 120 should be located on the extension line of the light filtering strip in the lower frame 600, so that the bottom end of the touch circuit board 220 can also extend to the light filtering strip in the lower frame 600, so that the touch circuit board 220 can extend to the corner position of the interactive tablet as much as possible, and the quality of the infrared signal at the corner position is ensured.

[0082] Regarding the limiting mode of the light filtering strip 210 in the side frame 100, please refer to FIG. 2 and FIG. 3 again. In an implementable embodiment, the light filtering strip 210 in the side frame 100 is located between the light filtering strip in the upper frame 500 and the light filtering strip in the lower frame 600, and the two ends of the light filtering strip 210 in the side frame 100 are respectively in abutment with the side surface of the light filtering strip in the upper frame 500 and the side surface of the light filtering strip in the lower frame 600, so that the light filtering strip 210 can be accurately limited without the need for additional limiting structures, thereby reducing the cost.

[0083] In actual application, the upper frame 500 and the lower frame 600 can be respectively provided with limiting structures at both ends, so as to limit the light filtering strip 210 and the touch circuit board 220 in the upper frame 500 and the lower frame 600 by the limiting structures at both ends, and thus the light filtering strip 210 in the side frame 100 can also be accurately limited by the side surface of the light filtering strip in the upper frame 500 and the lower frame 600, without changing the width of the light filtering strip in the upper frame 500 and the lower frame 600.

[0084] In order to facilitate understanding of the application, the application provides the following specific assembly steps for realizing the assembly of the touch assembly 200 without disassembling the frame assembly:

[0085] Step one: assemble the touch circuit board 220 into the installation cavity 211 of the corresponding light filtering strip 210 to form the touch assembly 200.

[0086] Step two: assemble the corresponding touch assembly 200 into the upper frame 500, and limit the position by using the limiting structure at both ends of the upper frame 500; assemble the corresponding touch assembly 200 into the lower frame 600, and limit the position by using the limiting structure at both ends of the lower frame 600.

[0087] Step three: insert one end of the corresponding touch assembly 200 of the side frame 100 into the end of the side frame 100 close to the upper frame 500, so that one end of the corresponding touch assembly 200 of the side frame 100 is placed in the space a, and the touch circuit board 220 is slid and ensured not to protrude from the other end of the light filtering strip 210.

[0088] Step four: push the other end of the corresponding touch assembly 200 of the side frame 100 into the accommodating groove 110 of the side frame 100 according to the arrow direction shown in FIG. 5, so that the touch assembly 200 is completely assembled into the side frame 100.

[0089] Step five: adjust the position of the light filtering strip 210 in the side frame 100, so that the two ends of the light filtering strip 210 abut against the side surface of the light filtering strip 210 in the upper frame 500 and the lower frame 600, respectively.

[0090] Step six: push the touch circuit board 220 in the side frame 100 towards the limiting part 120 through the assembly hole 212, so that the touch circuit board 220 abuts against the limiting part 120; and attach the limiting part 300 on the touch circuit board 220 in the side frame 100, so that the limiting part 300 extends out of the assembly hole 212 and extends to the outside of the light filtering strip 210.

[0091] Step seven: place the to-be-clamped part 400 on the support surface 213, assemble the pressing block 300 on the side frame 100, clamp the to-be-clamped part 400 by the pressing block 300 and the support surface 213, so as to fix the to-be-clamped part 400; at the same time, the side of the pressing block 300 away from the limiting part 120 abuts against the limiting part 300, so as to limit the touch circuit board 220 in the side frame 100 by the limiting part 120 and the pressing block 300 cooperating with the limiting part 400.

[0092] Based on the same inventive concept, the application further provides another interactive tablet, which can at least include a side frame 100 and a touch assembly 200. The side frame 100 has a receiving groove 110 and a limiting part 120 located at one end of the receiving groove 110. The touch assembly 200 can include a light filtering strip 210, a touch circuit board 220 and a limiting piece 230. The light filtering strip 210 is embedded in the receiving groove 110 and has a mounting cavity 211 and an assembly hole 212. The touch circuit board 220 is installed in the mounting cavity 211 and can slide along the length direction of the mounting cavity 211. The assembly hole 212 is located on the side of the light filtering strip 210 and communicates with the mounting cavity 211. When the touch circuit board 220 abuts against the limiting part 120 at one end, the limiting piece 230 is connected with the touch circuit board 220 through the assembly hole 212, and the limiting piece 230 abuts against the side of the assembly hole 212 away from the limiting part 120.

[0093] Through the above scheme, the touch circuit board 220 is limited by abutting against the limiting part 120 at one end and by the limiting piece 230 connected with the side of the touch circuit board 220 and abutting against the side of the assembly hole 212 away from the limiting part 120. The limiting mode of the touch circuit board 220 is changed, so that the other end of the side frame 100 does not need to be provided with the limiting part 120, leaving a space a for the touch assembly 200 to be assembled into the receiving groove 110 without disassembling the frame assembly. In this way, the operator can assemble the touch assembly 200 without disassembling the frame assembly, so as to avoid the touch assembly 200 in the frame assembly being displaced due to multiple disassembly and assembly, affecting the touch precision, improving the touch accuracy, and further optimizing the user experience. Similarly, when the touch assembly 200 is damaged, the frame assembly does not need to be disassembled through a complex disassembly process, saving the time required for maintenance, maintenance and replacement of parts, and saving labor costs. At the same time, compared with the above limiting mode of the touch circuit board 220, the limiting piece 230 does not need to abut against the side of the pressing block 300, so that the assembly hole 212 and the mounting position of the pressing block 300 do not need to be bound, reducing the processing difficulty.

[0094] Preferably, the interactive tablet further includes an upper frame 500 and a lower frame 600. The above-mentioned side frame 100 has two, and the two side frames 100 are oppositely arranged. The upper frame 500 and the lower frame 600 are oppositely arranged, and the upper frame 500, the lower frame 600 and the two side frames 100 are surrounded to form a rectangular ring structure. The light filtering strip 210 is located between the light filtering strip 210 in the upper frame 500 and the light filtering strip 210 in the lower frame 600, and the two ends of the light filtering strip 210 abut against the side of the light filtering strip 210 in the upper frame 500 and the side of the light filtering strip 210 in the lower frame 600, respectively.

[0095] It should be noted that the specific structure of the side frame 100, the touch control assembly 200, the limiting member 230, the upper frame 500 and the lower frame 600 can refer to the content in the above embodiments, and will not be repeated here.

[0096] Based on the same inventive concept, the application also provides a frame assembly, which at least includes an upper frame 500, a lower frame 600 and two side frames 100, wherein the upper frame 500 and the lower frame 600 are oppositely arranged, and the two side frames 100 are oppositely arranged, and the upper frame 500, the lower frame 600 and the two side frames form a quadrilateral ring structure. The side frame 100 has a receiving groove 110 and a limiting portion 120, the limiting portion 120 is located at one end of the receiving groove 110, and the other end of the receiving groove 110 is provided with a space a.

[0097] Through the above scheme, the touch control assembly 200 can utilize the space a at the other end of the receiving groove 110 to realize the assembly of the touch control assembly 200 into the receiving groove 110 without disassembling the frame assembly. In this way, the operator can realize the assembly of the touch control assembly 200 without disassembling the frame assembly. Similarly, when the touch control assembly 200 is damaged, it is no longer necessary to disassemble the frame assembly through a complex disassembly process, thereby saving the time required for maintenance, maintenance and replacement of parts, and saving labor costs.

[0098] It should be noted that the specific structure of the side frame 100, the limiting portion 120, the upper frame 500 and the lower frame 600 can refer to the content in the above embodiments, and will not be repeated here.

[0099] Based on the same inventive concept, the application also provides a touch control assembly 200, which at least includes a light filtering strip 210, a touch control circuit board 220 and a limiting member 230, wherein the light filtering strip 210 has a mounting cavity 211 and an assembly hole 212, the mounting cavity 211 penetrates through both ends of the light filtering strip 210, and the assembly hole 212 is located on the side surface of the light filtering strip and communicates with the mounting cavity 211. The touch control circuit board 220 is installed in the mounting cavity 211, and the touch control circuit board 220 can slide along the length direction of the mounting cavity 211. The limiting member 230 is connected with the touch control circuit board 220, and the limiting member 230 extends to the outside of the mounting cavity 211 through the assembly hole 212.

[0100] Through the above scheme, the touch control circuit board 220 realizes the limiting in at least one direction by the limiting member 230 connected on the side surface thereof, which changes the existing limiting mode of the two ends of the touch control circuit board 220. In the application, at least one end of the touch control circuit board 220 does not need to be provided with the limiting member 230, thereby leaving a space a, and the touch control assembly 200 can be assembled into the receiving groove 110 without disassembling the frame assembly.

[0101] In the embodiment, the touch assembly 200 can be assembled in the side frame 100, or can be assembled in the upper frame 500 and the lower frame 600, which is not limited in the application.
