Description

[Technical field]

[0001] The present disclosure relates to the field of computer technology, for example to interactive intelligent panels. [Background technology]

[0002] An interactive intelligent panel is an integrated intelligent device that realizes human-computer interaction by controlling the contents displayed on the panel using touch technology.

[0003] In the prior art, many interactive intelligent panels are packaged in a form that is framed by a frame 1'. Referring to FIG. 1, a schematic diagram of the structure of an interactive intelligent panel in the prior art is shown. The interactive intelligent panel is provided with a glass plate 2', a touch display unit 3', an optical film 4', and a back plate 5' in sequence within a frame 1'. When the edge of the structure is framed by a frame 1', the glass plate 2' is prevented from falling off mainly by a fixing bracket 6' and adhesive attachment. Since it is not acceptable for the glass fixing bracket 6' to directly apply force to the touch display unit 3', the glass plate 2' needs to protrude by a certain width in the direction of the fixing bracket 6' to facilitate attachment. In order to prevent the optical film 4' and the touch display unit 3' from directly contacting each other and to protect the touch display unit 3', it is necessary to add a middle frame 8' and use the middle frame 8' to hold the optical film 4' to prevent the optical film 4' from being displaced in the thickness direction of the optical film 4'. In addition, the positioning posts 7' are crimped and joined to the back plate 5' to fix the optical film 4', thereby preventing the optical film 4' from being displaced in the width direction of the optical film 4'. Therefore, in the above structure, black edges are generated at the edges of the interactive intelligent panel, as shown in area A in Figure 1, which affects the visual effect and usage effect of the user. Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present disclosure is to provide an interactive intelligent panel that has a narrow frame and occupies a large proportion of the effective display area. [Means for solving the problem]

[0005] The present specification provides an interactive intelligent panel, which includes a frame, a touch display unit, an optical film, a diffusion plate, a light-emitting unit and a back plate, a first fixing portion and a second fixing portion are provided on an inner wall of the frame with a gap therebetween in a thickness direction of the touch display unit; the touch display unit is fixed to the first fixing part, The optical film, the diffusion plate, the light emitting unit and the back plate are sequentially stacked to provide an interactive intelligent panel that is fixed to the second fixing portion on a side thereof away from the first fixing portion. Effect of the Invention

[0006] The interactive intelligent panel disclosed herein fixes the touch display unit with a first fixing part provided on the inner wall of the frame, and fixes the optical film with a second fixing part, thereby preventing direct contact between the touch display unit and the optical film, thereby avoiding the problem that the attachment area required for attachment using a fixing bracket and adhesive is too large, and the problem that an additional middle frame needs to be added to isolate the touch display unit and the optical film, and further solving the problem in the prior art that the frame is wide due to the optical film being held down by the middle frame, resulting in a small proportion of the effective display area.

[0011] Referring to FIG. 2, which is a structural schematic diagram of an interactive intelligent panel in one embodiment of the present application, the interactive intelligent panel includes a frame 1, a touch display unit 2, an optical film 3, a diffusion plate 4, a light-emitting unit 5 and a back plate 6.

[0012] A first fixing portion 11 and a second fixing portion 12 are provided on the inner wall of the frame 1 with a gap therebetween in the thickness direction of the touch display unit 2.

[0013] The touch display unit 2 is fixed to the first fixing portion 11.

[0014] The optical film 3 , the diffusion plate 4 , the light emitting unit 5 and the back plate 6 are laminated in this order and fixed to the side of the second fixing portion 12 away from the first fixing portion 11 .

[0015] In one embodiment, the display surface of the touch display unit 2 faces the front of the interactive intelligent panel, and the front of the interactive intelligent panel disclosed in this technical solution refers to the surface for displaying images and videos to the user and receiving touch operations.

[0016] In one embodiment, the interactive intelligent panel body may include a touch identification and position determination module for identifying touch commands, a control unit for controlling the screen display by the touch display unit 2 and the response to the touch commands, a microphone for collecting nearby people's voices or environmental sounds, a speaker for playing audio, a camera for collecting image information, a network module for communication, etc., which are not specifically limited and will not be described in detail here.

[0017] In one embodiment, referring to FIG. 3, which is a schematic diagram of an assembly method in one embodiment of the present application, the installation method of the interactive intelligent panel in one embodiment of the present application is as follows. First, the outer side of the first fixing part 11 of the frame 1 is placed downward, and the touch display unit 2 is attached to the inner side of the first fixing part 11 by adhesive. Here, the inner side of the first fixing part 11 is the side closer to the display surface, and the inner side of the first fixing part 11 is the side closer to the second fixing part 12. The optical film and the diffusion plate 4 are placed on the side of the second fixing part 12 away from the first fixing part 11, and the combination of the light-emitting unit 5 and the back plate 6 is hung and fixed on the upward end of the frame 1 in order. Here, the above-mentioned upward end of the frame 1 is the end of the frame 1 that faces upward when the outer side of the first fixing part 11 of the frame 1 is placed downward. The above mounting method adopts an upside-down mounting method, and the frame 1 is an integrated unit of the frame, inner frame, and fixed bracket of the conventional technology, thereby reducing the number of assembly parts and the difficulty of assembly, and improving assembly efficiency.

[0018] In one embodiment, the interactive intelligent panel is often applied in fields such as group meetings, multi-person learning, and multi-person games, so that the size of the embodiment of the interactive intelligent panel is highly demanding. Specifically, the interactive intelligent panel of the present application is a large-sized interactive intelligent panel, usually larger than 75 inches, which provides a better experience for touching and viewing by multiple people. Meanwhile, such a large-sized interactive intelligent panel is usually mounted on a wall or supported by a bracket, but since its front size is already large, if its thickness is also too large, it will bring a heavy and dull visual effect to people, which will greatly affect the visual experience of people. The structure of the interactive intelligent panel of the present application can improve the assembly efficiency, and can also reduce the structure of the plate glass fixing bracket 6' and the middle frame 8' required for the interactive intelligent panel of the prior art, greatly reduce the thickness of the interactive intelligent panel, and avoid the dull visual effect brought to users when mounted on a wall or placed on a bracket, greatly improving the visual experience of users.

[0019] In one embodiment, the touch display unit 2 is fixed by the first fixing part 11 provided on the inner wall of the frame 1, and the optical film 3 is fixed by the second fixing part 12, preventing the touch display unit 2 and the optical film 3 from coming into direct contact with each other, thereby avoiding the problem that the attachment area is too large when using a fixing bracket and adhesive for attachment, and the problem that it is necessary to add an inner frame to isolate the touch display unit 2 and the optical film 3. There is an optical distance (i.e., a gap) between the back plate 6 and the optical film 3, so please check how to fix the optical film 3 via the back plate 6 and the second fixing part 12.

[0020] In one embodiment, the diffusion plate 4 can convert a point light source or a line light source into a surface light source, making the brightness of the screen displayed on the interactive intelligent panel more uniform and improving the display effect, thereby improving the visual experience of the user.

[0021] Furthermore, the first fixing portion 11 extends along the outer edge of the frame 1 into the frame.

[0022] Specifically, if the first fixing part 11 does not extend into the frame along the outside of the frame 1, part of the side wall of the frame 1 will protrude beyond the display surface of the first fixing part 11, i.e., a recess will be formed between the first fixing part 11 and the inside of the frame 1, causing a problem that dirt that has accumulated in the recess and is hidden will be difficult to clean. On the other hand, by making the first fixing part 11 extend into the frame along the outer edge of the frame 1, the outer surface of the first fixing part 11 can be aligned as closely as possible with the edge of the frame, avoiding cleaning problems caused by the recess and improving the appearance effect of the interactive intelligent panel.

[0023] Furthermore, the outer surface of the frame 1 is formed by the outer surface of the first fixing portion 11 and the outer edge of the frame 1 close to the first fixing portion 11, and a step is provided at the edge away from the second fixing portion 12 of the touch display unit 2, and the step and the first fixing portion 11 engage with each other so that the display surface of the engaged touch display unit 2 and the outer surface of the frame 1 are flush with each other.

[0024] In one embodiment, since the embodiments of the present application require each layer to be installed upside down, if the outer surface of the touch display unit 2 is flush with the outer surface of the frame 1, it is easier to increase stability when each subsequent layer is placed face down.

[0025] Furthermore, the second fixed portion 12 extends from the center of the inner side of the frame 1 into the frame.

[0026] In one embodiment, the second fixing portion 12 extends from the center of the inside of the frame 1 into the frame, thereby providing sufficient mounting space even at the end side away from the first fixing portion 11 of the frame 1, making it easier to mount the optical film 3, diffusion plate 4, light-emitting unit 5 and backplate 6, and improving convenience of mounting.

[0027] Furthermore, a protruding plug connection portion 121 is provided on the side of the second fixing portion 12 away from the first fixing portion 11, a first plug connection hole is provided in the optical film 3, and a second plug connection hole is provided in the diffusion plate 4, and the plug connection portion 121 is fitted into the first plug connection hole and the second plug connection hole in turn.

[0028] In one embodiment, referring to FIG. 4, there is shown a structural schematic diagram of the plug-in connection portion 121 in the embodiment of Example 1 of the present application. By fitting the plug-in connection portion 121 into the plug-in connection holes of the optical film 3 and the diffusion plate 4, the left and right wobble of the optical film 3 and the diffusion plate 4 can be avoided, the fixing stability of the optical film 3 can be further improved, the effect of the light divergence and light uniformity can be improved, and the display effect of the interactive intelligent panel can be further improved.

[0029] In one embodiment, the length of the plug connection part 121 may be slightly higher than the total thickness of the optical film 3 and the diffusion plate 4, so that a part of the tip of the plug connection part 121 extends out of the diffusion plate 4 after the plug connection part 121 is fitted into the plug connection holes of the optical film 3 and the diffusion plate 4. In actual production, an engagement cap may be used to engage with the part of the tip of the plug connection part 121 extending out of the diffusion plate 4, so that the engagement cap tightly fixes the optical film 3 and the diffusion plate 4 to the plug connection part 121, thereby preventing the optical film 3 and the diffusion plate 4 from sliding in the thickness direction of the optical film 3, and after the back plate 6 is fixed to the frame, a certain width gap is maintained between the back plate 6 and the optical film 3, forming an optical distance. In addition, by providing a threaded portion on the portion extending from the diffusion plate 4 at the tip of the plug-in connection portion 121, a nut that fits this threaded portion can be tightened to this threaded portion, and the nut can then tightly fix the optical film 3 and diffusion plate 4 to the plug-in connection portion 121, thereby preventing the optical film 3 and diffusion plate 4 from sliding in the thickness direction of the optical film 3.

[0030] Preferably, referring to FIG. 5, which is a structural schematic diagram of the plug-in connection part in the embodiment of the first embodiment of the present application, the plug-in connection part 121 may be several discontinuous sheet-like protrusions.

[0031] Furthermore, referring to Figure 6, which is a structural schematic diagram of a frame in an embodiment of Example 1 of the present application, frame 1 includes four sub-frames 101 located on each edge, and the four sub-frames 101 are connected head to tail in sequence to form a rectangular frame body, and four corners are formed.

[0032] Referring to Fig. 7, it is a structural schematic diagram of a frame in the embodiment of the first embodiment of the present application. For convenience of explanation, the figure shows a schematic diagram of two adjacent sub-frames 101 and one corner fixing member 102, and the end structure of the remaining sub-frames 101 is the same as that shown in Fig. 7. Here, each sub-frame 101 is provided at both ends with a sub-frame fixing plate 13 (not shown in Fig. 6), and the sub-frame fixing plate 13 is provided with a sub-frame fixing screw hole 131.

[0033] The picture frame 1 further includes four corner fixing members 102 (not shown in FIG. 6) for fixing the sub-picture frames 101 .

[0034] Each corner fixing member 102 includes two fixing sheets 14, and one end of the two fixing sheets 14 is fixed to each other so as to form a right angle between the two fixing sheets 14. The two fixing sheets 14 are each provided with a corner fixing screw hole 141 that is the same size as the sub-frame fixing screw hole 131 and is located in a corresponding position.

[0035] The corner fixing members 102 are provided on the sub-frame fixing plates 13 at the respective corners, and the corner fixing members 102 are fixed to the corners formed by the sub-frames 101 by passing the sub-frame fixing screws through the corner fixing screw holes 141 and the sub-frame fixing screw holes 131 in order.

[0036] In one embodiment, referring to FIG. 7 , adjacent ends of two sub-frames 101 are brought close together to form a vertical corner, and the sub-frame fixing plates 13 of the two sub-frames 101 form a right-angle corner, in which the corner fixing member 102 is placed above this right-angle corner, and frame fixing screws are respectively passed through each corner fixing screw hole 141 of the corner fixing member 102 to fix the two sub-frames 101 downward, thereby improving the stability and dismantling ability of the frame 1.

[0037] 7, in one embodiment, the extending direction of the sub-frame fixing plate 13 and the second fixing part 12 are the same, and a groove having a certain width is formed between the sub-frame fixing plate 13 and the second fixing part 12. Specifically, the width of the groove may be set to match the total thickness of the optical film 3 and the diffusion plate 4, so that the edges of the optical film 3 and the diffusion plate 4 can be tightly inserted into the groove, and the optical film 3 and the diffusion plate 4 can be further prevented from sliding in the thickness direction of the optical film 3.

[0038] Furthermore, backplate screw holes are provided on the edges of the backplate 6. A backplate fixing plate 15 is provided on each sub-frame 101, and the installation direction of the backplate fixing plate 15 is parallel to the edges of the sub-frame 101. The backplate fixing plate 15 is provided with backplate fixing screw holes 151 that are the same shape as the backplate screw holes and correspond in position to the backplate screw holes, and the backplate 6 is fixed to the rectangular frame formed by the sub-frames 101 by passing backplate fixing screws through the backplate screw holes and backplate fixing screw holes 151 in that order.

[0039] In one embodiment, referring to FIG. 7 , at the end of the frame 1 away from the first fixed portion 11, a backplate fixing plate 15 extending inward is provided, and the backplate 6 is fixed to the frame 1 by a backplate fixing screw, and further allows the backplate 6 to cover the light-emitting unit 5 fixed inside it, thereby enhancing the stability of the interactive intelligent panel.

[0040] Preferably, in a specific implementation process, in addition to the screws, the back plate 6 and the back plate fixing plate 15 may have locking holes, and the back plate 6 may be fixed by other fasteners such as snap fasteners, which will not be described in detail here.

[0041] Furthermore, the backplate fixing plate 15 and the sub-frame fixing plate 13 in the sub-frame 101 have a height difference, and the backplate fixing plate 15 is closer to the outside of the frame 1, so that after the corner fixing member 102 is fixed to the rectangular frame body, the outer surface of the corner fixing member 102 and the outer surface of the backplate fixing plate 15 become flush with each other.

[0042] In one embodiment, after the corner fixing member 102 is installed, the outer surface of the corner fixing member 102 and the outer surface of the backplate fixing plate 15 become flush with each other, allowing the backplate 6 to be placed and fixed more stably, and preventing the backplate 6 from curling up or rattling after installation.

[0043] Preferably, the edge of the frame close to the backplate fixing plate 15 is made slightly higher than the backplate fixing plate 15, so that after the backplate 6 is fixed to the rectangular frame formed by the sub-frame 101, the outer surface of the backplate 6 and the edge of the frame 1 close to the backplate fixing plate 15 are flush with each other, thereby avoiding waste of material from the protruding portion of the frame 1. In addition, since it is necessary to place each unit inside the frame 1 using a robot hand or a human hand during the assembly process, making the outer surfaces of the frame 1 and the backplate 6 flush with each other can lower the barrier height of the frame 1 and reduce the difficulty of assembly.

[0044] Furthermore, the touch display unit 2 includes a liquid crystal screen, a touch capacitor and a glass plate which are stacked in sequence.

[0045] In one embodiment, after the touch display unit 2 is assembled, the order from the outer surface of the frame 1 to the inside is the glass plate, the touch capacitor, and the LCD screen. At this time, the touch display unit 2 including the glass plate is all fixed inside by the first fixing part 11, which avoids the problem that a large amount of adhesive and a large attachment area are required to firmly attach the glass plate to the outside of the frame 1, and significantly reduces the width of the black edge of the frame 1 while ensuring the robustness of the fixation.

[0046] Preferably, the glass sheet is tempered glass, which can greatly increase the robustness of the interactive intelligent panel.

[0047] Furthermore, the optical film 3 includes at least one of a diffusion sheet, a brightness enhancing sheet, and a reflection sheet.

[0048] Preferably, the optical film 3 has a three-layer structure, in which the three-layer structure is a diffusion sheet, a brightness enhancement sheet and a reflection sheet respectively, so as to uniformly diffuse the incident light beam from a point light source, and output it as a divergent light source, thereby eliminating the spots occurring on the light-emitting unit, widening the illumination angle, and effectively eliminating the lighting blind spots.

[0049] As described above, the interactive intelligent panel according to the embodiment of the present application fixes the touch display unit with the first fixing part provided on the inner wall of the frame, fixes the optical film with the second fixing part, and prevents the touch display unit and the optical film from coming into direct contact with each other, thereby avoiding the problem that the attachment area required for attachment using the fixing bracket and adhesive is too large, and the problem that the touch display unit and the optical film need to be isolated by adding an inner frame, and further solving the problem that the frame is wide and the effective display area is small due to the optical film being held down by the inner frame in the prior art. By extending the first fixing part into the frame along the outer edge of the frame, the display surface of the first fixing part can be aligned as much as possible with the edge of the frame, avoiding the cleaning problem caused by the dent, improving the appearance effect of the interactive intelligent panel, and improving the convenience of user operation. By making the outer surface of the touch display unit and the outer surface of the frame flush with each other, the stability of each subsequent layer placed face down can be improved. The second fixing part is provided with a plug-in connection part, and the optical film and the diffusion plate are provided with corresponding plug-in connection holes, thereby preventing the optical film and the diffusion plate from wobbling from side to side, further improving the stability of the optical film fixing, improving the light diffusion and light uniformity effects, and further improving the display effect of the touch display unit. The frame and the back plate are fixed with fastening screws, which improves the stability of the interactive intelligent panel structure and improves the convenience and efficiency of installation.

Any conversion of an equivalent structure or equivalent process using the contents of the specification and drawings of the present utility model, or any direct or indirect application to other related fields, shall be included in the patent scope of the present utility model.
