Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, and particularly relates to a virtual simulation experiment teaching device. Background Art

[0002] Virtual simulation is a technology that uses a system to imitate another real system. Virtual simulation is actually a computer system that can create and experience a virtual world. Such a virtual world is generated by a computer and can be a reproduction of the real world or a conceived world. Users can interact with the virtual world naturally through various sensing channels such as vision, hearing, and touch. It creates a three-dimensional virtual world for users in a simulation manner to reflect the changes and interactions of entity objects in real time.

[0003] When conducting virtual simulation teaching, it is necessary to project the content of virtual simulation for the convenience of teachers and students to learn. Since there are more teachers and students in some courses, the seats of teachers and students are relatively wide.

Several embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] Please refer to Figures 1 to 4 , which shows a virtual simulation experiment teaching device in an embodiment of the present utility model, including a base 10, a rotary mounting assembly 20, a longitudinal adjustment assembly 30, a longitudinal angle adjustment assembly 40, a projector 50, a projection platform 60, and a lateral angle adjustment assembly 70.

[0039] The rotary mounting assembly 20 is disposed on the upper surface of the base 10. The longitudinal adjustment assembly 30 is mounted on the rotary mounting assembly 20 through the longitudinal angle adjustment assembly 40. The projector 50 is provided on the longitudinal adjustment assembly 30. The projection platform 60 is disposed on one side of the projection direction of the projector 50. The projection platform 60 is disposed on the upper surface of the lateral angle adjustment assembly 70. Among them, the rotary mounting assembly 20 rotates based on the base 10 to adjust the first projection angle of the projector 50 through the longitudinal adjustment assembly 30 and the longitudinal angle adjustment assembly 40. The longitudinal adjustment assembly 30 and the longitudinal angle adjustment assembly 40 are respectively used to adjust the projection height and the second projection angle of the projector 50. The lateral angle adjustment assembly 70 is used to adjust the projected angle of the projection platform 60.

[0040] It can be understood that by rotating the mounting component 20, the longitudinal angle adjustment component 40 and the longitudinal adjustment component 30 can be driven, so that the projection angle of the projector 50 on the longitudinal adjustment component 30 can be adjusted horizontally. And by the longitudinal angle adjustment component 40, the longitudinal angle of the longitudinal adjustment component 30 can be adjusted, so that the longitudinal projection angle of the projector 50 can be adjusted. The longitudinal adjustment component 30 can be used to adjust the height, so that the projection height of the projector 50 can be adjusted. Thus, the projection angle of the projector 50 can be adjusted horizontally, longitudinally and in terms of height. And by the horizontal angle adjustment component, the horizontally projected angle of the projection platform 60 is adjusted, so that when the projection platform 60 faces various angles, the content projected on the projector 50 can be projected onto the projection platform 60, and thus the teachers and students in each seat can see the projection content on the projection platform 60.

[0041] Specifically, in this embodiment, the rotation mounting component 20 includes a first rotating shaft 21 and a mounting seat 22. The first rotating shaft 21 is arranged on the upper surface of the base 10, the mounting seat 22 is connected to the first rotating shaft 21, and the longitudinal adjustment component 30 is connected to the mounting seat 22 through the longitudinal angle adjustment component 40.

[0042] It should be noted that the first rotating shaft 21 can rotate on the base 10, and the torque of its rotation is relatively large. Therefore, after the first rotating shaft 21 rotates, it will stop at the rotated position. The rotation of the first rotating shaft 21 will drive the mounting seat 22 to rotate, and the mounting seat 22 will drive the projector 50 to rotate through the longitudinal angle adjustment component 40 and the longitudinal adjustment component 30, so as to achieve the adjustment of the horizontal angle of the projection of the projector 50.

[0043] Specifically, in this embodiment, the longitudinal adjustment component 30 includes a connecting rod 31, a telescopic rod 32 and a positioning pin 33. The bottom of the connecting rod 31 is connected to the longitudinal angle adjustment component 40, the telescopic rod 32 is sleeved on the connecting rod 31, a plurality of positioning holes 34 are provided on the outer surfaces of the telescopic rod 32 and the connecting rod 31, the positioning pin 33 is inserted into the positioning holes 34, and a mounting plate 51 is fixedly provided at the top of the telescopic rod 32. The projector 50 is mounted on the mounting plate 51.

[0044] It can be understood that in specific implementation, by pulling out the positioning pins in the positioning holes 34 of the telescopic rod 32 and the connecting rod 31, and then pulling the telescopic rod 32, the telescopic rod 32 can be extended and retracted on the outer surface of the connecting rod 31, so as to achieve the purpose of adjusting the height of the mounting plate 51 at the top of the telescopic rod 32, and further adjust the height of the projector 50 on the mounting plate 51, so as to achieve the purpose of adjusting the projection height of the projector 50.

[0045] Specifically, in this embodiment, the longitudinal angle adjustment assembly 40 includes a fixing part 41, a connecting part 42, and a bolt 43. The fixing part 41 is fixedly arranged on the upper surface of the rotary mounting assembly 20. The connecting part 42 is fixedly arranged on the upper surface of the fixing part 41. The bolt 43 penetrates through the connecting part 42, and the bottom of the longitudinal adjustment assembly 30 is arranged in the connecting part 42 and penetrated by the bolt 43. The fixing part 41 includes a fixing plate 411, a plurality of fixing members 412, and a plurality of locking members 413. The plurality of fixing members 412 are fixedly arranged at equal intervals on the bottom of the fixing plate 411 by the plurality of locking members 413. The plurality of fixing members 412 are fixedly connected to the upper surface of the rotary mounting assembly 20.

[0046] It should be noted that the bottom of the connecting rod 31 is arranged in the connecting part 42 and penetrated by the bolt 43, so that the connecting rod 31 can rotate around the axis of the bolt 43, thereby achieving the purpose of adjusting the angle of the connecting rod 31. The fixing member 412 is fixedly connected to the upper surface of the mounting seat 22, so that the longitudinal angle adjustment assembly 40 can be stably arranged on the mounting seat 22.

[0047] Specifically, in this embodiment, the transverse angle adjustment assembly 70 includes a mounting frame 71, a second rotating shaft 72, and a rotating seat 73. The projection platform 60 is mounted on the mounting frame 71. The top of the second rotating shaft 72 is arranged at the bottom of the mounting frame 71. The bottom of the second rotating shaft 72 is rotatably arranged in the rotating seat 73. Two sides of the bottom of the mounting frame 71 are symmetrically connected with support columns 74. A telescopic column 75 is sleeved on the support column 74. The bottom of the telescopic column 75 is arranged in a frustum structure.

[0048] It should be explained that the second rotating shaft 72 can rotate in the rotating seat 73, and the torque of rotation is relatively large. After the second rotating shaft 72 rotates, it can stop at the rotated position, so that the projection platform 60 can stably stop at the rotated position. After adjusting the angle, at this time, pull the telescopic column 75 on the outer surface of the support column 74, so that the bottom of the telescopic column 75 can contact the ground, so that the transverse angle adjustment assembly 70 is stably arranged on the ground. And because the bottom of the telescopic column 75 is arranged in a frustum structure, the telescopic column 75 is more stable when contacting the ground.

[0049] In summary, for the virtual simulation experiment teaching device in the above embodiments of the present utility model, the horizontal projection angle of the projector 50 can be adjusted through the rotation mounting assembly 20 via the longitudinal adjustment assembly 30 and the longitudinal angle adjustment assembly 40. The projection height of the projector 50 can be adjusted through the longitudinal adjustment assembly 30, and the longitudinal projection angle of the projector 50 can be adjusted through the longitudinal angle adjustment assembly 40. The projection platform 60 can be rotated by the horizontal angle adjustment assembly 70 to adjust the projected angle of the projection platform 60, so that the device can simply, quickly and widely adjust the projection angle and the angle of the projected projection platform, so that teachers and students at all angles can view the projection content.
