[0026] The following will cooperate with the drawings and embodiments to detail the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0027] As Figure 1 -5 shows an embodiment of the present utility model. To achieve the above object, the present utility model provides the following technical solution: A power multimedia device convenient for maintenance, including an installation box 1. The top of the installation box 1 is connected with a cover plate 14 through a hinge. The cover plate 14 can seal the opening of the installation box 1. Two partitions 12 with a gap are arranged in parallel inside the installation box 1. Two gears 121 are installed on the rear side wall of the partition 12 close to the rear side wall inside the installation box 1. Two groups of placement grooves 15 are arranged on the inner side wall of the installation box 1. Each group of placement grooves 15 is two symmetrically arranged ones, respectively used for clamping the two partitions 12. There is a gap between the two partitions 12 and the inner wall of the installation box 1, and the two partitions 12 have the same height, and the two gears 121 have the same height.

[0028] Furthermore, a lifting mechanism is provided between the inner rear side wall of the installation box 1 and the partition 12 close to it. The lifting mechanism includes a U-shaped plate 2 that is movably attached to the inner rear side wall of the installation box 1. A plurality of card slots 21 are equidistantly arranged on the front side wall of the U-shaped plate 2. A card plate 22 is clamped inside the card slot 21. The bottom end of the card plate 22 is fixedly connected to a support plate 23 perpendicular to it. And a roller 24 is movably connected to the middle position of the side surface of the card plate 22. Rack plates 25 are fixedly provided on the inner side walls of the two vertical plates on both sides of the U-shaped plate 2. The two rack plates 25 are respectively engaged with two gears 121. A whiteboard assembly 3 located between the two partitions 12 is installed at the top end of the support plate 23. A plurality of vertical through slots are symmetrically arranged on the two partitions 12. The width of the through slot is greater than the width of the support plate 23. A part of the roller 24 penetrates through the through slot of the partition 12 and extends to the other side of the partition 12. The support plate 23 also penetrates through the through slots of the two partitions 12 at the same time. When the lifting mechanism is lifted or lowered, the support plate 23 moves up and down along the vertical through slots of the two partitions 12 without contacting the partitions 12. A part of the roller 24 is located on the other side of the partition 12 and contacts the rear side surface of the whiteboard assembly 3, increasing the contact points between the whiteboard assembly 3 and the lifting mechanism, which helps to improve the installation stability of the whiteboard assembly 3. The roller 24 can roll during the rising process. When the whiteboard assembly 3 is taken out upward from the support plate 23, the fit between the roller 24 and the whiteboard assembly 3 changes from sliding friction to rolling friction, thereby reducing the friction force with the whiteboard assembly 3 and lowering the difficulty of taking out the whiteboard assembly 3. At the same time, it can prevent scratches on the rear side surface of the whiteboard assembly 3.

[0029] Furthermore, two motor boxes 11 are installed on the outer rear surface of the installation box 1. A motor is installed inside the motor box 11. The output end of the motor movably penetrates to the inside of the installation box 1 and is connected to the gear 121 through a shaft rod. By driving the gear 121 to rotate with the motor, the rack plate 25 engaged with it can be driven to move up and down during the rotation of the gear 121, and then drive the U-shaped plate 2 to move up and down. The motor provides a power source for the lifting mechanism. The support plate 23 in the lifting mechanism drags the whiteboard assembly 3 to make a lifting movement in the installation box 1, which is convenient to move the whiteboard assembly 3 out of the box during use and store the whiteboard assembly 3 in the box when not in use, having a good protective effect on the whiteboard assembly 3 and helping to extend the service life of the equipment.

[0030] Furthermore, two limiting slots 13 are symmetrically arranged on the left and right side walls of the installation box 1. A screw rod 131 slidably penetrates through the limiting slot 13. One end of the screw rod 131 extends to the inside of the installation box 1 and is connected to the U-shaped plate 2. The other end of the screw rod 131 extends to the outside of the installation box 1 and is sleeved with a nut, which plays a role in limiting the lifting process of the U-shaped plate 2, preventing the U-shaped plate 2 from shaking during lifting and ensuring the stable operation of the lifting mechanism.

[0031] When the above-described embodiment is in operation, when using 3, the motor is started to drive the gear 121 to rotate. During the rotation of the gear 121, the rack plate 25 engaged therewith can be driven to move up and down, thereby driving the U-shaped plate 2 to move up and down. The motor provides a power source for the lifting mechanism. The support plate 23 in the lifting mechanism drags the whiteboard assembly 3 to move up and down in the installation box 1, facilitating the removal of the whiteboard assembly 3 from the box during use and storing the whiteboard assembly 3 in the box when not in use. It has a good protective effect on the whiteboard assembly 3, helps to extend the service life of the device. During the lifting process, the support plate 23 moves up and down along the vertical through grooves of the two partition plates 12 without contacting the partition plates 12. A part of the roller 24 is located on the other side of the partition plate 12 and contacts the rear surface of the whiteboard assembly 3, increasing the contact points between the whiteboard assembly 3 and the lifting mechanism, which helps to improve the installation stability of the whiteboard assembly 3. The roller 24 can roll during the rising process. When the whiteboard assembly 3 is taken out upward from the support plate 23, the fit between the roller 24 and the whiteboard assembly 3 changes from sliding friction to rolling friction, thereby reducing the friction force with the whiteboard assembly 3, reducing the difficulty of removing the whiteboard assembly 3, and at the same time preventing scratches on the rear surface of the whiteboard assembly 3.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
