[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0029] See also Figure 1 and Figure 2 The present invention discloses an AI educational device for a smart education campus, comprising a projection screen 1 and a screen support device for keeping the projection screen 1 in an unfolded state. The screen support device comprises an outer support mechanism and an inner support mechanism detachably connected to the outer support frame. The outer support mechanism is used to fix and keep the inner support mechanism in an unfolded state, the projection screen 1 is detachably mounted on the inner support mechanism, and the inner support mechanism supports the entire back side of the projection screen 1.
[0030] Based on the above scheme, the inner supporting mechanism is supported by the outer supporting mechanism to ensure the fixation and unfolding of the inner supporting mechanism, and then the projection screen is supported by the inner supporting mechanism to ensure that the projection screen is in an unfolded state. Moreover, unlike the projection screen supporting structure in the prior art which mostly provides local support for the projection screen, the inner supporting mechanism supports the entire back side of the projection mold. This supporting method of the present scheme not only ensures that the projection screen is unfolded and provides sufficient supporting force for the back side of the projection screen, but also effectively avoids deformation of the projection screen layout part, or local depression or bulge to the viewing side, especially in a windy environment, to avoid depression or bulge of the projection screen layout part, ensure that the projection screen remains flat as a whole, avoid deformation or distortion of the picture on the projection screen, ensure that the picture on the projection screen remains normal, ensure that the picture can be viewed normally, and improve the user experience.
[0031] In the prior art, the support of the projection screen is generally supported by a rectangular area surrounded by four fixed rods connected end to end, or only two horizontal or two vertical fixed rods are used to unfold, support and fix the projection screen, or several fixed rods are added on the back of the projection screen, which support the horizontal fixed rods and / or vertical fixed rods for installing the projection screen, and also support the centerline position of the projection screen. However, these support methods still have a large area of blank space on the back of the projection screen that is not supported. During the use of the projection screen, these unsupported blank areas will be locally deformed, making the surface of the projection screen unable to be flat or horizontal, and the surface of the projection screen will be partially concave or convex. At this time, the picture projected on the projection screen will be distorted due to the local deformation of the projection screen. The screen support device in this scheme, especially the inner support device, solves this problem well. The inner support device supports the entire back of the projection screen, avoiding the deformation of the projection screen layout.
[0032] In the technical solution, the outer support mechanism includes two vertical support bars 2 and two horizontal support bars 3 arranged opposite to each other. The horizontal support bars 3 and the vertical support bars 2 are arranged alternately and connected end to end to form a rectangular support area. The inner support mechanism is placed in the rectangular support area and is detachably connected to the horizontal support body and the vertical support body respectively. The setting of the outer support mechanism is to realize the support and fixation of the inner support mechanism, provide an installation position for the inner support mechanism, ensure that the inner support mechanism is in an unfolded state, and provide conditions for the inner support mechanism to realize the unfolding and support of the projection screen.
[0033] In the present technical solution, the internal support mechanism includes an air pump 6 and an inflatable grille 4 adapted to the rectangular support area. The air pump 6 inflates the inflatable grille 4 to keep the inflatable grille 4 in an expanded state. The inflatable grille 4 in the expanded state is detachably fixedly connected to the lateral support body and the vertical support bar 2.
[0034] In the above scheme, by using an inflatable grille, the size of the inflatable grille is set to a state that is adapted to the size of the projection screen, or the length and / or width of the inflatable grille is greater than the length and / or width of the projection screen, ensuring that the inflatable grille supports the entire back side of the projection screen, and can also support projection screens of different sizes, with a wide range of applications and good flexibility.
[0035] In the above scheme, the projection screen is supported by using an inflatable grille. According to the characteristics of the inflatable grille, after the gas in the inflatable grille is released, the inflatable grille can be folded and stored, occupying a small area and being easy to carry and transport.
[0036] In the above scheme, the projection screen is supported by an inflatable grille, which has a certain deformation ability and has little friction with the projection screen, thus not causing wear to the projection screen and extending the service life of the projection screen.
[0037] In the above scheme, by adopting the inflatable grille, it can be used after being inflated, does not require complicated installation and connection, is easy to operate, and is convenient for quickly setting up, unfolding or disassembling and storing the projection screen.
[0038] In the above scheme, by adopting the inflatable grille, the weight is light, and the requirements for the overall installation or fixed base or pedestal of the educational equipment are relatively small. Moreover, by adopting the inflatable grille, if the inflatable grille accidentally dumps or collapses, it will not cause great harm and damage to the surrounding people, buildings or objects, and has good safety.
[0039] In the above scheme, by adopting the inflatable grille, the space on the inflatable grille can be set smaller as needed, that is, the back of the projection screen can be effectively supported to the greatest extent, and the back of the projection screen can be fully supported to ensure that the projection screen is fully supported, the screen support is reliable, and the local deformation of the projection screen is avoided.
[0040] In the technical solution, the inflatable grille 4 includes a transverse air channel 42 and a vertical air channel 41 that are interconnected and in an integral shape. The outer end of the transverse air channel 42 is detachably fixedly connected to the vertical support bar 2, and the vertical air channel 41 is detachably fixedly connected to the transverse support bar 3. The transverse air channel 42 and the vertical air channel 41 form a rectangular support area to ensure effective fixed support for the projection screen and improve the support capacity. At the same time, it is also convenient for the inflatable grille 4 to be connected as a whole, improve the strength of the inflatable grille itself, and the transverse air channel and the vertical air channel are stretched against each other to avoid deformation of the inflatable grille itself.
[0041] In the above scheme, the inflatable grille formed by the horizontal air channel 42 and the vertical air channel 41 facilitates the air pump to inflate and deflate the inflatable grille, thereby increasing the inflation and deflation speed of the inflatable grille and increasing the speed of unfolding, supporting and storing the projection screen.
[0042] In the technical solution, the transverse air passage 42 is connected and communicated with the air passage to form a plurality of rectangular support blocks, and each of the rectangular support blocks supports the projection screen 1. Each support block supports the projection screen at the same time, with good support effect and high support strength.
[0043] In the present technical solution, a first pipe is connected to the air inlet of the air pump 6, a second pipe is connected to the exhaust port of the air pump 6, a first valve is provided on the first pipe and is connected to the external environment, a second valve is provided on the second pipe and is connected to the air port 44 of the inflation grille, a third pipe and a fourth pipe are respectively connected to the first pipe and the second pipe, a third valve is provided on the third pipe and is connected to the air port 44 of the inflation grille and the air inlet of the air pump 6, and a fourth valve is provided on the fourth pipe and is connected to the exhaust port of the air pump 6 and the external environment.
[0044] In the above scheme, by setting the first pipeline, the second pipeline, the third pipeline and the fourth pipeline, and by reasonably controlling the on and off of each valve, one air pump can be used to inflate and deflate the inflatable grille, and only one air pump is used, thereby reducing the use of air pumps.
[0045] In the above scheme, when the inflatable grille is inflated by the air pump, the third valve and the fourth valve are closed, the first valve and the second valve are opened, and the air pump draws air from the air through the first pipe and delivers it to the inflatable grille through the second pipe. When the inflatable grille is deflated by the air pump, the first valve and the second valve are closed, the third valve and the fourth valve are opened, and the air pump draws air from the inflatable grille through the third pipe and discharges it to the external environment through the fourth pipe, thereby deflation of the inflatable grille, improving the deflation capacity of the inflatable grille, reducing the deflation work intensity of the inflatable grille, avoiding manual deflation or manual squeezing deflation, and the operation is simple and fast, and one-button operation can be achieved.
[0046] In this technical solution, the AI educational equipment for smart education campus also includes a mounting bracket 5, the air pump 6 is connected to the inflatable grille 4 and fixed on the mounting bracket 5, and the inflatable grille 4 is symmetrically distributed on both sides of the mounting bracket 5. The mounting bracket realizes the installation of the air pump and the inflatable grille. The inflatable grille 4 is symmetrically distributed on both sides of the mounting bracket 5 to ensure that the inflatable grille is evenly stressed after installation, and also ensure that the mounting bracket is evenly stressed, improve the stability of the inflatable grille, and avoid problems such as tilting of the inflatable grille during use.
[0047] In the above scheme, the inflatable grilles 4 are symmetrically distributed on both sides of the mounting support 5, and the inflatable grilles on both sides of the mounting support are connected by a connecting pipe 43, and the connecting pipe 43 is provided with an air port 44 of the inflatable grille. The air port 44 of the inflatable grille is connected to an air pump, and the inflatable grilles on both sides of the mounting support are inflated simultaneously through the air pump, ensuring that the inflatable grilles are quickly deployed and in a balanced and stable state.

The short transverse support bar is detachably fixed to the vertical support bar and is also connected to the mounting support. In this way, when the projection screen is stored, the vertical support bar and the short transverse support bar are separated, and the short transverse support bar is rotated toward the mounting support 5 so that the short transverse support bar is close to the mounting support, which is convenient for storing the short transverse support bar. At the same time, the vertical support bar is also close to the mounting support, so that the storage of the short transverse support bar and the vertical support bar is realized, and the storage is convenient and quick, and the volume is small after storage, which is convenient for handling and packaging. In addition, the projection screen and the inflatable grille are folded and placed together on the mounting support to realize the overall storage of the educational equipment.
[0049] In the present technical solution, a storage portion 7 is provided on the mounting support 5, and the storage portion 7 is used to store the short horizontal support bar and the vertical support bar 2.
