[0002] In today's digital age, multimedia interactive devices have been widely used in many fields such as education, exhibitions, and commercial displays. As users' requirements for multimedia experience continue to increase, multimedia interactive devices not only need to have powerful functions and clear display effects, but also need to make breakthroughs in ease of use, equipment maintenance, and protective performance.

[0003] Traditional multimedia interactive devices are often relatively fixed in structural design. For example, the height and angle of the multimedia display screen are usually difficult to flexibly adjust according to the needs of different users, which may cause inconvenience to some users during use and affect the interactive experience. Moreover, in terms of equipment maintenance, the display screen is easily contaminated with dust, fingerprints and other stains. If there is a lack of an effective cleaning mechanism, it will not only reduce the display clarity, but may also damage the display screen due to accumulation of stains. In addition, in some public places or environments with large traffic, multimedia interactive devices are easily impacted by external forces. Devices that lack sufficient protective structures may frequently malfunction, shortening the service life of the equipment and increasing maintenance costs.

[0004] In order to solve these problems, there is an urgent need to develop a new type of multimedia interactive device that can provide stable support while facilitating users to freely adjust the height and angle of the display screen, and has an efficient cleaning function and a reliable protective structure to adapt to the usage requirements of different scenarios, improve user experience, and ensure long-term stable operation of the equipment.

[0025] In the present embodiment, in order to provide shielding protection for the multimedia display screen 21 without affecting its normal display and presentation, and at the same time, the mesh panel 43 and the top spray can be set to prevent debris from entering the shell 4 from the rectangular opening while satisfying the heat dissipation, a rectangular opening is provided on the top of the shell 4, and a mesh panel 43 is fixedly installed in the rectangular opening, an installation opening is provided on one side of the shell 4, and a high-transmittance glass 41 corresponding to the multimedia display screen 21 is fixedly installed in the installation opening, and a ceiling 42 located directly above the installation opening is fixedly installed on the top of the shell 4.

[0026] In this embodiment, in order to prevent debris from entering the shell 4 from the opening without affecting the air circulation in the shell 4, the bottom of the shell 4 is set to be open, and an elastic dustproof cloth is fixedly installed in the opening.

[0027] The cleaning strip 33 includes a thin steel strip and a plurality of conductive fibers. The conductive limiter maintains contact with the multimedia display screen. The thin steel strip combined with the conductive fiber can effectively reduce the thickness of the cleaning strip, thereby avoiding the influence of the cleaning strip on the picture when it is placed horizontally on the display surface of the multimedia display screen. At the same time, it can have a static electricity removal effect without affecting normal cleaning.

[0028] In addition, the cleaning strip 33 located near the high-transmittance glass can also be extended in width to contact the inner side of the high-transmittance glass 41. It should be noted that the position in contact with the inner side of the high-transmittance glass 41 should also be made of conductive fibers.

[0029] Working principle: When in use, first turn on the power supply, and control the rotation of the screw sleeve 13 through the motor 132 in cooperation with the driving gear 133 and the driven gear 134, so that the height of the installation frame 2 can be controlled to be adjusted under the cooperation of the screw rod 131, so that the user can adjust the height of the multimedia display screen 21 according to actual needs to adapt to the usage habits of different users. In the process of upward adjustment of the installation frame 2, the winding wheel 34 can be controlled to unwind the pull rope 341, so that the rotation of the lower shaft 3 can be controlled, and the two cleaning strips 33 can be controlled to clean the multimedia display screen 21 under the cooperation of the pulley 31 and the belt 32. Then, the worm 145 is controlled by the motor 2 144 to drive the worm wheel 143 to rotate, so that the inclination angle of the installation plate 15 and the touch screen 151 can be adjusted through the support block 142, and then the user manually controls the installation plate 15 to rotate to the desired direction. After the adjustment is completed, turn on the touch screen 151 and the multimedia display screen 21, and then perform interactive operations through the touch screen 151 and the multimedia display screen 21.

[0030] After use, the height of the mounting frame 2 is lowered through the motor 132 in cooperation with the driving gear 133, the driven gear 134, the screw sleeve 13 and the screw rod 131. With the cooperation of the torsion spring 351 and the partition 35, the rotating shaft 3 below can be controlled to rotate in the opposite direction and the winding wheel 34 can be controlled to reel in the pull rope 341, ensuring that the cleaning strip 33 can return to the initial position and clean the multimedia display screen 21 again during the resetting process.

[0031] The protective design of the shell 4 ensures the safety of the multimedia display screen 21 when it is impacted by external forces. The buffer spring 55 provides a buffering effect when the shell 4 is collided, reducing the direct impact on the mounting frame 2, thereby protecting the multimedia display screen 21 from damage. The design of the mesh plate 43, the ceiling 42 and the elastic dustproof cloth not only ensures the normal circulation of air in the shell 4, but also prevents dust and debris from entering the shell 4, ensuring the cleanliness of the inside of the device and the normal operation of the equipment.
