Further, a frame 40 is installed at the outer side of the bracket body 10, the frame 40 is used as an edge trim of product equipment, when in use, the bracket can be arranged along the length direction of the bracket body 10, and under the condition that the bracket body 10 is arranged at the outer edges of the cover plate component 20 and the back plate component 30, the frame 40 provided at the outside of the stand body 10 can serve to shield the edge of the apparatus, so as to shield the inner part of the screen, the frame 40 preferably adopts a strip-shaped structure matched with the bracket body 10, and in the application state, the frame body 10 is matched with a plurality of sections of frames 40, the plurality of sections of frames 40 are respectively connected with the corresponding frame body 10 along the length direction, form the subassembly and link to each other in proper order and enclose the installation region who delimits with support body 10, apron subassembly 20 and backplate subassembly 30 all set up in the installation region, are connected with support body 10 respectively, and frame 40 shelters from the outer fringe department at mutual dull and stereotyped. Here, the specific structure of the interactive flat plate is not specifically limited, and the frame 40 may be a frame 40 formed by multi-section mutual splicing, where the frame 40 is disposed on the outer edge of the cover plate 20 and matches the shape of the outer edge of the cover plate 20. In general, the shape of the cover plate assembly 20 in the orthogonal projection direction is rectangular, the length of the frame 40 matches the length of one side edge of the cover plate assembly 20, the frames 40 are connected by connecting members such as corner members, or by welding, fastening, or integral molding, the bracket body 10 and the frame 40 can be connected by processes such as extrusion, rolling, bending, and the like, taking a rectangular display module as an example, and the display module has two opposite long sides and short sides, respectively, and is in a rectangular structure.

In this embodiment, the outer side of the bracket body 10 is located between the first supporting portion 11 and the second supporting portion 12 to define a first locking portion 13, the inner side of the frame 40 correspondingly defines a second locking portion 41, and the second locking portion 41 is locked and fixed to the first locking portion 13, where the specific structures of the first locking portion 13 and the second locking portion 41 are not limited, and the first locking portion 13 and the second locking portion 41 may be detachable components arranged on the bracket body 10 and the frame 40 through connectors, or may be fixed to the bracket body 10 and the frame 40 through welding, bonding, and other processes.

In order to improve the connection strength between the stent body 10 and the frame 40, the first locking portion 13 and the second locking portion 41 are respectively matched with the surface structures for connecting with each other, so as to increase the contact area between the first locking portion 13 and the second locking portion 41, thereby improving the stability of the frame 40 locked on the stent body 10. Here, in a state where the interactive flat plate is horizontally placed, the connection surface between the first locking attachment portion 13 and the second locking attachment portion 41 may be one or a combination of more of a plane, an inclined surface, a wavy surface, and the like with respect to a horizontal plane.

Because the frame 40 is disposed outside the support body 10, during the process of carrying or using and adjusting the interactive tablet, the frame 40 may be easily turned out toward the front side or the rear side of the interactive tablet by an external force or other factors, in order to limit the turning-out angle of the frame 40, so as to prevent the frame 40 from being excessively turned out to cause deformation damage or even fall off from the support body 10, in this embodiment, three matching manners for preventing the frame 40 from turning out are provided between the support body 10 and the frame 40, and the matching manners between the two are further improved based on the above-mentioned locking and fixing of the first locking portion 13 and the second locking portion 41.

As shown in fig. 1 to 4, in the first mode, the bracket body 10 is provided with a first rotation preventing portion 50, the frame 40 is provided with a second rotation preventing portion 60, and the first rotation preventing portion 50 and the second rotation preventing portion 60 are respectively disposed at the front and rear sides of the first locking portion 13 and the second locking portion 41, that is, the first rotation preventing portion 50 is disposed at the rear side of the first locking portion 13, the second rotation preventing portion 60 is disposed at the front side of the second locking portion 41, or the first rotation preventing portion 50 is disposed at the front side of the first locking portion 13, and the second rotation preventing portion 60 is disposed at the rear side of the second locking portion 41.

The first rotation preventing part 50 and the second rotation preventing part 60 are respectively used for abutting against the frame 40 when the frame 40 is turned forwards or backwards relative to the bracket body 10, or abutting against the bracket body 10 by the second rotation preventing part 60 so as to limit the turning angle of the frame 40. In the present embodiment, for example, the first rotation preventing part 50 is disposed at the rear side of the first locking part 13, and the second rotation preventing part 60 is disposed at the front side of the second locking part 41, when the rear side of the frame 40 receives a moment applied in the front side direction, the second locking part 41 is locked and fixed with the first locking part 13, and the second locking part 41 of the frame 40 can turn outwards around the first locking part 13 relative to the bracket body 10 toward the front side of the apparatus with the first locking part 13 as a fulcrum, and because the front side of the second locking part 41 is provided with the second rotation preventing part 60, when the frame 40 turns outwards in the front direction, the second rotation preventing part 60 can abut against the bracket body 10 or the first locking part 13 when the frame 40 receives a force or turns outwards to a certain angle, so as to limit the front side turning direction of the frame 40; on the contrary, when the front side of the frame 40 receives a torque applied in the rear direction, the second locking portion 41 of the bracket body 10 turns outwards around the first locking portion 13 towards the rear side of the apparatus relative to the bracket body 10 with the first locking portion 13 as a fulcrum, and because the rear side of the first locking portion 13 is provided with the first rotation preventing portion 50, when the frame 40 turns outwards forwards, the first rotation preventing portion 50 can abut against the frame 40 or the second locking portion 41 when the frame 40 is stressed or turns outwards to a certain angle, so as to limit the turning-outwards direction of the rear side of the frame 40.

As shown in fig. 5, in the second embodiment, the bracket body 10 is provided with a first rotation preventing part 50 and a second rotation preventing part 60, and the first rotation preventing part 50 and the second rotation preventing part 60 are respectively disposed at the front and rear sides of the first locking part 13, and are configured such that when the frame 40 is turned forward or backward with respect to the bracket body 10, the first rotation preventing part 50 or the second rotation preventing part 60 can abut against the frame 40, and the turning angle of the frame 40 is limited.

As shown in fig. 6, in the third embodiment, the frame 40 is provided with a first rotation preventing part 50 and a second rotation preventing part 60, and the first rotation preventing part 50 and the second rotation preventing part 60 are respectively disposed at the front and rear sides of the second locking part 41, and are configured such that when the frame 40 is turned forward or backward with respect to the stand body 10, the first rotation preventing part 50 or the second rotation preventing part 60 can abut against the stand body 10, and the turning angle of the frame 40 is limited.

The limiting principle of the second and third modes is the same as that of the first mode, and the first rotation preventing part 50 and the second rotation preventing part 60 are both used for abutting against the frame 40 or the bracket body 10 when the frame 40 is stressed, so that the front side and the rear side of the frame 40 are limited. Through foretell limit structure, the angle that limits frame 40 and turn up in front side or rear side direction reduces frame 40 deformation degree, ensures equipment appearance integrality, simultaneously, has also avoided frame 40 excessively to turn up and the damage that leads to or the problem that drops from support body 10, has reduced the risk that equipment deformation damaged in transport or accommodation process, has also improved follow-up user's use and has experienced.

As a further solution of the above embodiments, the first locking portion 13 and the second locking portion 41 are both plate-shaped structures, one end of the first locking portion 13 is connected to the stent body 10, the other end of the first locking portion 13 extends towards the outside of the stent body 10, one end of the second locking portion 41 is connected to the frame 40, and the other end of the second locking portion 41 extends towards the inside of the frame 40, specifically, in order to ensure the connection strength between the stent body 10 and the frame 40, the first locking portion 13 and the second locking portion 41 are flat plate-shaped structures with a certain thickness, the front side and the rear side thereof are two surfaces parallel to each other, and the outside of the first locking portion 13 and the inside of the second locking portion 41 are two surfaces perpendicular to the front side and the rear side thereof, respectively, in each matching mode of the present embodiment, each opposite two surfaces between the first locking portion 13 and the second locking portion 41 can be butted and locked, if the front side of the first locking portion 13 is attached to and locked with the rear side of the second locking portion 41, or the rear side of the first locking portion 13 is overlapped and locked with the front side of the second locking portion 41, or the outer side of the first locking portion 13 is abutted and locked with the inner side of the second locking portion 41, since the two surfaces of the first locking portion 13, which are engaged with each other in the connection state of the first locking portion 13 and the second locking portion 41, are flat surfaces, the contact area between the first locking portion 13 and the second locking portion 41 is increased, and a connection structure for primarily preventing the frame 40 from turning outwards is formed.

As shown in fig. 1 to 4, the first locking portion 13 and the second locking portion 41 of the present embodiment are stacked, and specifically, the rear side surface of the first locking portion 13 is adhered and fixed to the front side surface of the second locking portion 41. As shown in fig. 5 to 6, the second and third engagement means are a connection means in which the outer side surface of the first locking portion 13 engages with the inner side surface of the second locking portion 41.

Further, the first locking portion 13 and the second locking portion 41 are respectively provided with corresponding fixing holes 70, a fixing member 71 can be disposed between the two fixing holes 70 to fix the first locking portion 13 and the second locking portion 41, and the fixing holes 70 respectively penetrate through the front and rear sides of the first locking portion 13 and the second locking portion 41. In this embodiment, the fixing hole 70 of the second locking portion 41 is a through hole, the fixing hole 70 of the first locking portion 13 is a threaded hole, and the fixing member 71 for locking the first locking portion 13 and the second locking portion 41 is a screw, the screw is in threaded connection with the threaded hole by passing through the through hole at the rear side of the screen fixing bracket assembly, and the second locking portion 41 is pressed and fixed on the first locking portion 13 by a screw head, so that the frame 40 is fixedly mounted on the bracket body 10.

Because the order of the interactive flat plate in the installation process is that the first supporting part 11 of the bracket body 10 is glued on the cover plate assembly 20, the frame 40 is installed on the bracket body 10, and finally the back plate assembly 30 is installed on the bracket body 10, an installation mode of entering screws from the rear side of the bracket assembly can avoid scratching the rear side of the cover plate assembly 20 in a state that the cover plate assembly 20 and the bracket body 10 are fixed, if a fixing hole 70 structure arranged from the inner side of the bracket body 10 to the outer side direction is adopted, the screws need to be installed from the inner side of the bracket body 10, and therefore the risk of damaging the cover plate assembly 20 is improved.

As a further improvement of the above, in order to reduce the width of the black edge formed on the cover plate assembly 20 by the bracket body 10, one end of the second supporting portion 12 is connected to the bracket body 10, the other end of the bracket body extends towards the outer side of the bracket body 10, a groove structure is formed between the second supporting part 12 and the first locking part 13, concretely, the bracket body 10 has a section with a shape of Contraband, the first supporting portion 11 protrudes from the front side of the stent body 10, and finally, the cross section of the stent body 10 is approximately in an F-shaped structure, however, in view of the above-mentioned arrangement of the fixing hole 70, the second supporting portion 12 inevitably interferes with the screw during the installation process, therefore, in the structure of the present embodiment, the second supporting portion 12 is provided with the clearance gap 121 at the position corresponding to the position of the first locking portion 13 having the fixing hole 70, so that the screw can be mounted on the first locking portion 13 through the clearance gap 121. The groove formed between the second support portion 12 and the first locking portion 13 just forms a space for accommodating the second locking portion 41, when the frame 40 is assembled on the bracket body 10, the second locking portion 41 is inserted into the groove and abuts against the first locking portion 13, the distance between the second support portion 12 and the first locking portion 13 is greater than the thickness of the second locking portion 41, so that the second locking portion 41 can be conveniently mounted and dismounted, the first locking portion 13 extends towards the frame 40, and the outer side surface of the first locking portion 13 is arranged close to the frame 40.

Because the second locking part 41 swings around the first locking part 13 as a fulcrum in the process of turning the frame 40 outward toward the front side or the rear side, the inner side surface of the second locking part 41 and the groove generate abnormal noise due to friction and collision in the process of turning the frame 40 outward, and in order to avoid the abnormal noise generated in the process of turning the frame 40 outward, gaps are formed between the outer side of the first locking part 13 and the inner side of the frame 40, and gaps are formed between the inner side of the second locking part 41 and the outer side of the bracket body 10. Thus, when the frame 40 is turned outwards towards the front side or the rear side, a certain margin gap is reserved between the outer side surface of the first locking part 13 and the frame 40 and between the inner side surface of the second locking part 41 and the bracket body 10, so that friction and collision between the two parts are avoided, and the problem of abnormal turning outwards of the frame 40 is solved.

As described above, the second rotation preventing portion 60 and the second locking portion 41 are spaced apart from each other, and the second rotation preventing portion 60 is also a plate-shaped structure, one end of which is connected to the frame 40, the other end of which extends toward the inner side of the frame 40, i.e., the side close to the stent body 10 in the installed state, and the second locking portion 41 and the second rotation preventing portion 60 are parallel to each other, so that a groove structure is formed between the second locking portion 41 and the second rotation preventing portion 60, which is the same as that between the first locking portion 13 and the first rotation preventing portion 50, and the cross section of which is substantially "Contraband", and the groove formed between the second supporting portion 12 and the second locking portion 41 just forms a space for accommodating the first locking portion 13, when the frame 40 is assembled to the stent body 10, the first locking portion 13 is inserted into the groove and abuts against the second locking portion 41, and the distance between the second supporting portion 12 and the second locking portion 41 is greater than the thickness of the first locking portion 13, to facilitate mounting and dismounting of the bezel 40. Finally, the first locking part 13 is installed between the second locking part 41 and the second rotation preventing part 60, and the second locking part 41 is installed between the first locking part 13 and the first rotation preventing part 50, so that a limiting structure of alternate engagement is formed between the stent body 10 and the frame 40.

Of course, a third rotation prevention portion, a fourth rotation prevention portion and the like may be further disposed on the frame 40 and the bracket body 10, and in the first matching manner, the same number of rotation prevention portions are respectively disposed on the frame 40 and the bracket body 10, and are alternately engaged with each other according to the above-mentioned structural arrangement manner, so as to further improve the limiting capability of the frame 40.

On the premise of the first embodiment, the first rotation preventing part 50 is disposed at the front side of the second supporting part 12, the first rotation preventing part 50 is protruded from the front surface of the second supporting part 12, and a certain gap is maintained between the first rotation preventing part 50 and the second locking part 41 to ensure that the second locking part 41 can be normally installed, and finally the first rotation preventing part 50 and the second locking part 41 are disposed opposite to each other, so that when the frame 40 is turned outwards towards the rear side, the second locking part 41 can be abutted against the first rotation preventing part 50 when the frame 40 is turned outwards to a certain angle, and when the frame 40 is turned outwards towards the front side, the second rotation preventing part 60 can be abutted against the first locking part 13 to achieve the above technical effects.

In this embodiment, the edge covering structures 42 are respectively extended from the front and back sides of the end of the frame 40 away from the bracket body 10, the length of the edge covering structures 42 can at least partially shield the side edges of the cover plate assembly 20 and the back plate assembly 30 when the screen fixing bracket assembly is applied to the screen assembly and the interactive flat plate, and the connection between the frame 40 and the bracket body 10 mainly plays a role in decoration, dust prevention or providing a certain structural strength for the bracket body 10.

Further, the glue dispensing groove 111 is concavely formed on the surface of the first supporting portion 11, and in the process of fixing the cover plate assembly 20, the glue dispensing AB is applied to the glue dispensing groove 111, the support body 10 and the cover plate assembly 20 are aligned, and the aligned support body 10 and the aligned cover plate assembly 20 are pressed together by a pressing machine for several minutes, thereby fixing the cover plate assembly 20.

It should be noted that, this embodiment also provides a screen assembly, including the above-mentioned screen fixing bracket assembly.

In the above-mentioned scheme, the cover plate assembly 20 is glued to the first support portion 11, and the back plate assembly 30 is fixedly connected to the second support portion 12 through the fixing member 71.

As another example, the interactive flat panel in this embodiment includes the screen assembly, the back plate assembly 30 includes a back plate and a backlight module, and the backlight module is fixed to the bracket body 10 through the back plate to adjust the brightness of the content displayed by the cover plate assembly 20. The cover plate assembly 20 includes a glass panel, a liquid crystal panel, and a touch panel laminated in sequence from a side far away from the bracket body 10 to a side close to the bracket body 10, so as to realize content display and touch functions.
