[0040] Embodiment 2

[0041] Please refer to Figure 4 , and on the basis of Embodiment 1, the lifting mechanism 7 is further obtained.

[0042] The lifting mechanism 7 includes a bidirectional screw rod 71. The left end of the bidirectional screw rod 71 is connected to the bottom of the left side of the inner wall of the first box body 1 near the front surface. A second motor 72 is fixedly connected to the bottom of the front surface on the right side of the first box body 1. Threaded sleeves 73 are symmetrically and threadedly connected to the left and right surfaces of the bidirectional screw rod 71. A fixing plate 76 is fixedly connected to the surface of the threaded sleeve 73. Limiting rods 74 are fixedly connected to the back surfaces of the bottom parts on the left and right sides of the inner wall of the first box body 1. Sliding sleeves 75 are symmetrically and slidably connected to the surfaces of the limiting rods 74. The top of the fixing plate 76 is fixedly connected to a first hinge bracket 77. An articulated rod 78 is hinged within the first hinge bracket 77. The other end of the articulated rod 78 is hinged to a second hinge bracket 79.

[0043] A hole matching the output shaft of the second motor 72 is provided on the right side of the first box body 1, and the output shaft panel of the second motor 72 penetrates and is rotatably connected within the hole. The output end of the second motor 72 is fixedly connected to the right end of the bidirectional screw rod 71.

[0044] The rear end of the fixing plate 76 is fixedly connected to the surface of the sliding sleeve 75. The sliding sleeve 75 and the limiting rod 74 limit the fixing plate 76, so that the two fixing plates 76 can only move towards each other as the bidirectional screw rod 71 rotates. The top of the second hinge bracket 79 is fixedly connected to the top of the inner wall of the second box body 3.

[0045] During the actual operation process, when this device is in use and the display screen 5 is not in use, the second protective plate 615 is pulled out from the first protective plate 614. After reaching a certain position, the second protective plate 615 is fixed in the first protective plate 614 with bolts 616. Then, the first motor 619 is started to rotate the second gear 6111. Since the second gear 6111 meshes with the first gear 617 and the diameter of the second gear 6111 is smaller than that of the first gear 617, the rotation of the second gear 6111 drives the first gear 617 to rotate slowly, thereby rotating the rotating shaft 612 and the connecting block 613. The rotation of the connecting block 613 causes the first protective plate 614 and the second protective plate 615 to flip over to cover the display screen 5, protecting the display screen 5 so that it will not be damaged due to collision. When the second protective plate 615 and the first protective plate 614 are flush with the display screen 5, the back of the rubber plate 624 will contact the front of the second connecting plate 622, thereby squeezing the spring 625. The squeezing force received by the spring 625 buffers the first protective plate 614 and the second protective plate 615, so that the first protective plate 614 and the second protective plate 615 will not touch the display screen 5;

[0046] Start the second motor 72. The operation of the second motor 72 causes the bidirectional screw 71 to move up and down. The rotation of the bidirectional screw 71 causes the two fixing plates 76 to move towards each other, thereby causing the two first hinge brackets 77 to move towards each other. The first hinge bracket 77 squeezes the hinge rod 78, thereby causing the top of the hinge rod 78 to move upward, further causing the second hinge bracket 79 to move upward, driving the second box body 3 to move upward in the first box body 1 to adjust the height of the display screen 5 to suit people of different heights.

[0047] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
