[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] For an example, please refer to... Figures 1-5 An electronic teaching device includes a protective box 1. A threaded rod 101 is rotatably connected to the bottom of the inner cavity of the protective box 1 via a bearing. A driving component is provided between the threaded rod 101 and the protective box 1. A connecting frame 102 is threadedly connected to the outer surface of the threaded rod 101. A mounting frame 103 is fixedly installed on the top of the connecting frame 102. A multimedia display screen 2 is provided on the front of the mounting frame 103. Limiting components are provided between the mounting frame 103 and the protective box 1 on both sides. The threaded rod 101, the connecting frame 102, and the driving component cooperate to drive the multimedia display screen 2 to rise and fall, so that the multimedia display screen 2 enters the protective box 1 when not in use, thereby protecting the multimedia display screen 2 from accidental collisions when not in use.

[0028] The multimedia display screen 2 is an existing component, and its specific structure and usage method are existing technologies, which will not be described in detail in this application.

[0029] Furthermore, the limiting component includes a limiting groove plate 105 installed on the inner wall of the protective box 1. A limiting plate 104 is inserted and connected to the inner wall of the limiting groove plate 105. The limiting plate 104 is fixedly connected to the side of the mounting frame 103. A second protective plate 106 located above the multimedia display screen 2 is fixedly connected between the limiting plate 104 and the top of the mounting frame 103. The limiting plate 104 and the limiting groove plate 105 cooperate with each other to limit the mounting frame 103, thereby improving the stability of the mounting frame 103 during use.

[0030] Furthermore, the driving component includes a worm gear 107 fixedly sleeved on the outer surface of the threaded rod 101. The worm gear 107 is connected to a worm 108. One end of the worm 108 is connected to a motor 109 via a coupling. The motor 109 is bolted to the bottom of the inner cavity of the protective box 1. The motor 109 can drive the worm 108 to rotate. During the rotation of the worm 108, it can drive the worm gear 107 to rotate, which in turn can drive the threaded rod 101 to rotate. The worm gear 107 and the worm 108 adopt a self-locking design.

[0031] Furthermore, the outer surface of the worm 108 is fitted with two support seats 110 through bearings. The bottom of the support seats 110 is connected to the bottom of the inner cavity of the protective box 1, and the support seats 110 can support the worm 108.

[0032] Furthermore, a limiting rod 111 is inserted and connected to the connecting frame 102. The bottom end of the limiting rod 111 is fixedly connected to the bottom of the inner cavity of the protective box 1. The limiting rod 111 can limit the connecting frame 102 to improve the stability of the connecting frame 102 during the lifting process.

[0033] Furthermore, the mounting bracket 103 is provided with a through hole 116 for the threaded rod 101 and the limiting rod 111 to pass through. The through hole 116 allows the damping shaft 113 to avoid the mounting bracket 103, so as to prevent interference between the limiting rod 111 and the threaded rod 101 and the mounting bracket 103.

[0034] Furthermore, the protective box 1 is fitted with a first protective plate 115 via a hinge. A buckle is provided between the side of the first protective plate 115 away from the hinge and the protective box 1. The buckle is an existing component, and its specific structure, unlocking and locking methods are all existing technologies, which will not be described in detail in this application. After opening the first protective plate 115, the components inside the protective box 1 can be inspected and maintained.

[0035] Furthermore, the bottom of the protective box 1 is provided with two damping pivots 113, and both damping pivots 113 are connected to a base plate 114. When the base plate 114 is rotated to be perpendicular to the second protective plate 106, it can support the protective box 1. During the overall transportation process, the base plate 114 can be rotated to be parallel to the second protective plate 106, which can reduce the situation where the base plate 114 protrudes and occupies space.

[0036] Furthermore, handles 112 are installed on both sides of the protective box 1. The handles 112 are designed to improve the hand leverage point during handling.

[0037] Furthermore, a remote control device 3 is installed at the bottom of the inner cavity of the protective box 1, and the remote control device 3 is connected to the motor 109. The remote control device 3 can be a two-way intelligent wireless remote control switch of the Tuoanda brand, model TAD-T80. This two-way intelligent wireless remote control switch is equipped with a remote control, which can remotely control the motor 109 to control the forward and reverse rotation of the motor 109.

[0038] The electronic teaching device provided by this utility model is used as follows:

[0039] Reference Figure 5 When the multimedia display screen 2 is needed, the motor 109 is started by controlling the remote control device 3. The motor 109 drives the worm gear 107 to rotate via the worm 108, which in turn drives the threaded rod 101 to rotate. During the rotation of the threaded rod 101, the mounting bracket 103 is raised via the connecting bracket 102, thereby raising the multimedia display screen 2. The motor 109 stops running when the multimedia display screen 2 is fully exposed. Figure 1 As shown;

[0040] After use, the motor 109 is started using the remote control included with the remote control device 3. The motor 109 drives the worm gear 107 to rotate via the worm 108, which in turn drives the reverse threaded rod 101 to rotate. During the reverse rotation of the threaded rod 101, the mounting bracket 103 is lowered via the connecting bracket 102, thereby causing the multimedia display screen 2 to descend. Once the multimedia display screen 2 has completely descended into the protective box 1, the operation of the motor 109 stops. Figure 5 As shown.
