DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0022] In the related art, the smart blackboard may include a main screen and a sub-screen. The main screen is mainly used to display images, and the sub-screen is mainly used to write on the blackboard. The main screen and the sub-screen are assembled by splicing. During assembly, the main screen and the sub-screen are assembled separately first, and then the main screen and the sub-screen are assembled together. The main screen includes a display screen. In order to protect the display screen, a light-transmitting panel is set on the display side of the display screen. The light-transmitting panel is used to protect the display screen. The light-transmitting panel can be made of materials with good light transmittance such as glass and acrylic; the light-transmitting panel can be fixed by a profile frame, and the light-transmitting panel and the profile frame are assembled by gluing. However, when the gluing method is adopted, the problem of inaccurate bonding positioning between the light-transmitting panel and the profile frame is easy to occur. When the main screen and the sub-screen are spliced, it is easy to cause a large gap between the main screen and the sub-screen; in addition, since the gluing fixation method is not easy to disassemble, when the light-transmitting panel has problems and needs to be repaired and replaced, the operation is more difficult, which easily leads to the scrapping of the entire display screen.

[0023] Based on the above, please refer to Figures 1 to 7The embodiment of the present application discloses a face frame assembly 100 of a smart blackboard. The face frame assembly 100 is arranged on the display side of the display screen, and the face frame assembly 100 can be fixed on the main frame of the smart blackboard. The face frame assembly 100 may include a light-transmitting panel 110, a first frame 120, a second frame 130, and a plurality of pressure plates 140. The first frame 120 is provided with a first slot 121, and the second frame 130 is provided with a second slot 131. The first slot 121 and the second slot 131 may be U-shaped slots, and the notch of the first slot 121 is arranged opposite to the notch of the second slot 131. The two opposite sides of the light-transmitting panel 110 may be respectively embedded in the first slot 121 and the second slot 131 to achieve preliminary fixation.

[0024] It should be noted that, when the light-transmitting panel 110 is installed on the smart blackboard, the two opposite sides of the light-transmitting panel 110 can be the upper edge and the lower edge of the light-transmitting panel 110, respectively. Correspondingly, the first frame 120 and the second frame 130 are respectively arranged on the upper edge and the lower edge of the light-transmitting panel 110 to form an upper frame and a lower frame; along the thickness direction of the light-transmitting panel 110, the size of the first groove body 121 and the second groove body 131 is slightly larger than the thickness of the light-transmitting panel 110, so as to facilitate the side edges of the light-transmitting panel 110 to extend into the first groove body 121 and the second groove body 131.

[0025] like Figures 1 to 5 As shown, the light-transmitting panel 110 includes a first surface 111 and a second surface 112 that are disposed opposite to each other, and two opposite groove walls of the first groove body 121 are respectively located on both sides of the light-transmitting panel 110 along its thickness direction, and similarly, two opposite groove walls of the second groove body 131 are also respectively located on both sides of the light-transmitting panel 110 along its thickness direction. When the light-transmitting panel 110 is embedded in the first groove body 121 and the second groove body 131, the second surface 112 of the light-transmitting panel 110 will contact the groove walls of the first groove body 121 and the groove walls of the second groove body 131. Multiple pressure plates 140 are located on the first surface 111 of the light-transmitting panel 110, and are detachably connected to the first frame 120 or the second frame 130 respectively. The connection method between the pressure plate 140 and the first frame 120 or the second frame 130 can be a snap connection, a bolt connection, etc. When the pressure plate 140 is connected to the first frame 120 or the second frame 130, the pressure plate 140 can abut against the first surface 111 of the light-transmitting panel 110, so that the second surface 112 of the light-transmitting panel 110 is in contact with the groove wall of the first groove body 121 and the groove wall of the second groove body 131, thereby further fixing the light-transmitting panel 110.

[0026] When there is a deviation in the assembly position between the light-transmitting panel 110 and the first frame 120 or the second frame 130, the pressing plate 140 can be loosened or removed from the first frame 120 or the second frame 130, and after adjusting the position of the light-transmitting panel 110 and the first frame 120 or the second frame 130, the pressing plate 140 can be used to press the light-transmitting panel 110 into the first groove body 121 and the second groove body 131 again.

[0027] From the above, it can be known that the face frame assembly 100 of the smart blackboard disclosed in the embodiment of the present application improves the relevant technology, and uses the first groove body 121 of the first frame 120 and the second groove body 131 of the second frame 130 to preliminarily fix the light-transmitting panel 110, and then uses the pressing plate 140 to further fix the light-transmitting panel 110. Since the pressing plate 140 is detachably connected to the first frame 120 or the second frame 130, respectively, it is convenient to flexibly adjust the positions of the light-transmitting panel 110, the first frame 120 and the second frame 130, thereby reducing the difficulty of installation; compared with the method of fixing the light-transmitting panel 110 to the surface of the frame profile by gluing in the related technology, when the light-transmitting panel 110 is disassembled, the present application is not easy to cause damage to the light-transmitting panel 110 and the frame, thereby reducing the cost of installation and maintenance.

[0028] Furthermore, if Figures 1 to 6 As shown, the pressure plate 140 may include a first wing plate 141, a second wing plate 142 and a side plate 143. The first wing plate 141 and the second wing plate 142 are arranged on the same side of the side plate 143 and are connected by the side plate 143 to form a U-shaped pressure plate 140. The first wing plate 141, the second wing plate 142 and the side plate 143 may adopt an integrated structure, or may be made separately and then assembled together by welding, bolting, etc.

[0029] The first wing plate 141 is disposed outside the first slot body 121 or the second slot body 131, and is detachably connected to the outer surface of the first frame 120 or the outer surface of the second frame 130, and the connection method may be snap connection, bolt connection, etc. The second wing plate 142 extends into the first slot body 121 or the second slot body 131, and abuts against the first surface 111 of the light-transmitting panel 110, thereby pressing the second surface 112 of the light-transmitting panel 110 against the slot wall of the first slot body 121 or the second slot body 131. The first slot body 121 or the second slot body 131 with a U-shaped structure cooperates with the U-shaped pressure plate 140, so as to realize double limit fixation of the light-transmitting panel 110, thereby reducing the problem of the first frame 120 and the second frame 130 turning outward.

[0030] In an optional embodiment of the present application, Figure 6As shown, the face frame assembly 100 may further include a fastener, which may be a screw, a pin, etc. The first frame 120 and the second frame 130 are both provided with a first mounting hole (the first mounting hole is located below the second mounting hole 144 and communicates with the second mounting hole 144, Figure 6 The first wing plate 141 is provided with a second mounting hole 144, and fasteners are provided through the first mounting hole and the second mounting hole 144, so that the pressing plate 140 is detachably connected to the first frame 120 or the second frame 130. The number of the first mounting holes and the second mounting holes 144 are equal and are arranged one by one.

[0031] Since the pressing plate 140 has a certain rigidity, in order to avoid the pressure of the pressing plate 140 causing damage to the light-transmitting panel 110, as shown in FIG. Figure 3 and Figure 6 As shown, a buffer pad 150 can be set between the pressure plate 140 and the light-transmitting panel 110. The buffer pad 150 can be made of rubber, silicone, foam or other materials. The buffer pad 150 can be only set in the area between the pressure plate 140 and the light-transmitting panel 110. In order to avoid rigid contact between the light-transmitting panel 110 and the first frame 120 or the second frame 130, continuously distributed buffer pads 150 can also be set on the side of the light-transmitting panel 110, which can further protect the light-transmitting panel 110.

[0032] In order to prevent the buffer pad 150 from falling off from between the pressure plate 140 and the light-transmitting panel 110, the buffer pad 150 can be bonded to the pressure plate 140, specifically, it can be bonded to the surface of the first wing plate 141 facing the light-transmitting panel 110; the buffer pad 150 can also be bonded to the first surface 111 of the light-transmitting panel 110, and the pressure plate 140 and the light-transmitting panel 110 can also be bonded to the buffer pad 150, which can further improve the stability of the installation of the light-transmitting panel 110.

[0033] like Figure 1 As shown, in order to apply sufficient pressure to the light-transmitting panel 110 so that it is fixed on the first frame 120 and the second frame 130, a plurality of pressing plates 140 are arranged at intervals along the extension direction of the first frame 120, and a plurality of pressing plates 140 are arranged at intervals along the extension direction of the second frame 130. The number and spacing of the pressing plates 140 on the first frame 120 and the second frame 130 can be appropriately adjusted according to the size of the light-transmitting panel 110.

[0034] The first frame 120 and the second frame 130 mentioned above only realize fixed protection for the upper and lower sides of the light-transmitting panel 110. For the left and right sides of the light-transmitting panel 110, Figures 1 to 7As shown, the face frame assembly 100 further includes a side frame 160 and an angle bracket 170. There are two side frames 160, which are respectively arranged at positions near the left and right edges of the first surface 111 of the light-transmitting panel 110 to support and protect the left and right sides of the light-transmitting panel 110. The angle bracket 170 is an L-shaped structure. The two ends of the side frame 160 are respectively connected to the first frame 120 and the second frame 130 through the angle bracket 170. When the angle bracket 170 is connected to the first frame 120 or the second frame 130, one end of the angle bracket 170 can extend into the first slot body 121 or the second slot body 131. The connection method of the angle bracket 170 with the side frame 160, the first frame 120, and the second frame 130 can be clamping, bolting, riveting, etc. Exemplarily, bolt holes can be respectively provided on the corner code 170 , the side frame 160 , the first frame 120 and the second frame 130 , and fastened with bolts. When the side frame 160 needs to be removed, the bolts can be unscrewed, which is beneficial to improving the installation and disassembly efficiency of the side frame 160 .

[0035] In order to facilitate the installation and positioning of the side frame 160 and prevent the side frame 160 from excessively extending into the first slot body 121 or the second slot body 131, as shown in FIG. Figure 1 to Figure 2 As shown, a raised first limiting portion 161 can be provided at both ends of the side frame 160, and a second limiting portion 180 can be provided at both the first frame 120 and the second frame 130. The first limiting portion 161 and the second limiting portion 180 are used to limit and cooperate, so that the side frame 160 can be smoothly placed at a predetermined position for installation. The first limiting portion 161 and the second limiting portion 180 can be in the shape of a plate, a column, etc. In this embodiment, the first limiting portion 161 and the second limiting portion 180 are both in the shape of a plate, and the contact surface of the first limiting portion 161 and the second limiting portion 180 is arc-shaped, which can reduce the contact stress to a certain extent.

[0036] like Figure 3 and Figure 7 As shown, in order to prevent the side frame 160 from slipping on the light-transmitting panel 110, an adhesive layer 190 can also be set between the side frame 160 and the light-transmitting panel 110. The adhesive layer 190 is respectively bonded to the side frame 160 and the light-transmitting panel 110, thereby improving the installation stability of the side frame 160 and the light-transmitting panel 110.

[0037] When the side frame 160 and the light-transmitting panel 110 are installed, if they are in contact with the adhesive layer 190 without accurate alignment, the side frame 160 and the light-transmitting panel 110 will be misaligned. For this reason, a protective layer can be provided on the outer surface of the adhesive layer 190 to isolate the adhesive layer 190 from the external environment. It should be noted that the outer surface of the adhesive layer 190 is the surface of the adhesive layer 190 that is not bonded to other components and is exposed. When the side frame 160 and the light-transmitting panel 110 are installed, the adhesive layer 190 can be firstly pasted on the first surface 111 of the light-transmitting panel 110, and the side of the adhesive layer 190 facing away from the first surface 111 is the outer surface of the adhesive layer 190, and the outer surface of the adhesive layer 190 is provided with a protective layer, and the protective layer can be a material such as isolation paper and a film; then, the two ends of the side frame 160 are locked to the first frame 120 and the second frame 130 by the corner code 170, and after the side frame 160 and the light-transmitting panel 110 are accurately aligned, the protective layer on the outer surface of the adhesive layer 190 is torn off, and the protective layer is separated from the adhesive layer 190, so that the outer surface of the adhesive layer 190 has stickiness, and then the side frame 160 and the adhesive layer 190 are bonded together to achieve further fixation of the side frame 160 and the light-transmitting panel 110.

[0038] Please refer to Figures 1 to 7 The embodiment of the present application also discloses a smart blackboard. The disclosed smart blackboard may include a sub-screen, a display screen and the above-mentioned face frame assembly 100. The face frame assembly 100 is arranged on the display side of the display screen to form a main screen. The main screen and the sub-screen are spliced ​​to form the above-mentioned smart blackboard. The number of sub-screens can be one, two or more, which can be selected according to actual usage requirements. For example, the number of sub-screens can be two, and the two sub-screens are respectively located on both sides of the main screen, and spliced ​​with the main screen to form the above-mentioned smart blackboard.

[0039] From the above, it can be known that the face frame assembly 100 of the smart blackboard disclosed in the embodiment of the present application improves the relevant technology, and uses the first groove body 121 of the first frame 120 and the second groove body 131 of the second frame 130 to preliminarily fix the light-transmitting panel 110, and then uses the pressing plate 140 to further fix the light-transmitting panel 110. Since the pressing plate 140 is detachably connected to the first frame 120 or the second frame 130, respectively, it is convenient to flexibly adjust the positions of the light-transmitting panel 110, the first frame 120 and the second frame 130, thereby reducing the difficulty of installation; compared with the method of fixing the light-transmitting panel 110 to the surface of the frame profile by gluing in the related art, when the light-transmitting panel 110 is disassembled, the present application is not easy to cause damage to the light-transmitting panel 110 and the frame, thereby reducing the cost of installation and maintenance of the smart blackboard.

[0040] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0041] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
