Description

Technical Field

[0001] This invention relates to the field of intelligent teaching equipment technology, and in particular to a holographic projection teaching device for virtual simulation experimental teaching in the humanities. Background Technology

[0002] Currently, holographic projection devices generally store image information through TF memory cards, and then display the image information in the TF memory card through control buttons or touch screens. Holographic projection teaching equipment is often used in humanities virtual simulation experimental teaching.

[0003] A patent with publication number CN109035886B discloses an interactive holographic projection teaching device. In this patent, during holographic projection teaching, the teaching image in the teaching system is sent to the control system. The control system controls the projector to project the image onto a pyramidal display screen. The projector's beam is projected onto multiple sides of the pyramidal display screen. The sides of the pyramidal display screen interfere and diffract the projected beam, thus forming a three-dimensional illusion at the center of the display screen. If the illusion is blurry, a rotating mechanism is used to align all sides of the pyramidal display screen with the projector, allowing the display screen to present the clearest and most complete three-dimensional illusion. However, this patent still has the following problems:

[0004] The aforementioned holographic projection teaching equipment is not easy to fold during use, making it difficult to store. When not in use for teaching, dust easily adheres to the outer wall of the holographic projection teaching equipment, and it occupies a certain amount of space, which is quite inconvenient. Furthermore, the holographic projection teaching equipment is not easy to move during teaching use, so adjusting its placement requires manual handling, which is quite inconvenient.

[0005] To address the above problems, it is necessary to design a holographic projection teaching device for virtual simulation experimental teaching in the humanities, thereby overcoming these issues. Summary of the Invention

[0017] Beneficial effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this invention, a holographic projection teaching device for virtual simulation experiments in the humanities is designed. A bidirectional lead screw rotates, driving a moving block to slide along the inner wall of a sliding baffle via a sliding rod at its top. This causes two sets of moving blocks to move towards each other, which in turn causes a moving plate to slide along the inner wall of a groove via the sliding block, thus moving the holographic projection teaching device. A rotating roller rotates the foldable components at an angle. The engagement of the first and second gears sequentially drives each set of rotating rollers to move and rotate, folding the four sets of baffles of the holographic projection teaching device. An electric telescopic rod moves the protective top cover to the top of the protective box to enclose it, facilitating the folding and storage of the holographic projection teaching device. The operation is simple.

[0020] 2. In this invention, a holographic projection teaching device for virtual simulation experimental teaching in liberal arts is designed. The universal wheels are used to improve the ease of movement of the protective box. The height of the anti-slip pad at one end is adjusted by the extension and retraction of the telescopic cylinder, which makes it easier to adjust whether the universal wheels support the ground and makes it easier to adjust the movement of the protective box.

The limiting plate 416 serves to support the bidirectional lead screws 410.

[0033] Please see the appendix Figure 1 and attached Figure 6 As shown, the movable component 3 includes a base 301 disposed on the outer wall of the bottom end of the protective box 1. The base 301 has an installation groove 305 in the middle. Each of the four corners of the base 301 is provided with a telescopic cylinder 302. One end of the telescopic cylinder 302 is connected to an anti-slip pad 303. Each of the four corners of the bottom end of the base 301 is provided with a caster wheel 304. The base 301 and the protective box 1 are detachably installed. The telescopic cylinder 302 and the anti-slip pad 303 are detachably connected. The caster wheel 304 and the base 301 are detachably installed.

[0034] One end of the telescopic cylinder 302 passes through the base 301 and is connected to the anti-slip pad 303, which facilitates the adjustment of the height of the base 301 by telescopic cylinder 302 and is supported on the ground by the anti-slip pad 303 at one end.

[0035] Workflow of this invention: The holographic projection teaching equipment for humanities virtual simulation experiments designed in this scheme operates by pushing the protective housing 1, which is moved via the casters 304 to facilitate adjustment of the placement position of the holographic projection teaching equipment 401. An external controller controls the telescopic cylinder 302 to drive one end of the anti-slip pad 303 to support the equipment on the ground, reinforcing the stability of the holographic projection teaching equipment 401. When the holographic projection teaching equipment 401 is retracted, the motor 409 is started, driving the bidirectional lead screw 410 to rotate. The rotation of the bidirectional lead screw 410 drives two sets of moving blocks 411 to slide against the inner wall of the sliding baffle 404 via the sliding rod 412 at its top, assisting the two sets of moving blocks... The moving blocks 411 move towards each other, thereby causing the two ends of the adjusting plate 413 to rotate. This causes the moving plate 414 to slide along the inner wall of the slide groove 406 via the sliding block 407 at the bottom. This causes the rotating roller 408 to move the clamping plate 405. The clamping plate 405 moves one piece of the holographic projection teaching device 401. By rotating the rotating roller 408, the holographic projection teaching device 401 is rotated to a horizontal position. Then, the four sets of holographic projection teaching device 401 pieces are placed horizontally in sequence. The electric telescopic rod 403 is retracted by the external controller, and the protective top cover 402 is placed on top of the protective box 1, which facilitates the folding of the holographic projection teaching device 401. The operation is simple.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
