Description

Technical Field

[0001] This invention relates to the field of educational demonstration devices, specifically to an educational device for demonstrating innovation and entrepreneurship education courses. Background Technology

[0002] Educational demonstration devices are the core carriers connecting theoretical knowledge with practical cognition. Their core design is to transform abstract concepts into intuitive experiences through visual presentation, operable interaction, and exploratory verification, adapting to different learning stages and subject scenarios. The core of educational demonstration devices is learner-centered, transforming learning from passive listening to active doing by accurately matching knowledge objectives, adapting to cognitive abilities, and integrating appropriate technologies, ultimately achieving deeper understanding, stronger memory, and greater interest. Since learners at different learning stages have significantly different cognitive abilities and knowledge objectives, the design of demonstration devices must precisely match their needs.

[0003] Existing innovation and entrepreneurship education demonstration devices are relatively intelligent, using electronic devices for demonstrations and teaching. However, when using electronic instruments for demonstrations, they usually use PPTs or pictures, but these are all viewed in one direction. When reviewing, it is necessary to flip through the PPTs or pictures, which is quite troublesome. When explaining physical pictures, it is not convenient to operate the actual entrepreneurial education pictures, and it is also inconvenient to view the relationship and sequence of the pictures. As a result, it is not easy for students to clearly see the sequence and interrelationship of each stage.

[0004] By combining the above problems, we find that existing demonstration and educational devices for innovation and entrepreneurship education courses are difficult to avoid simultaneously when used. Even if they can be solved, they require the assistance of external tools, thus failing to achieve the desired effect. Therefore, we propose an innovation and entrepreneurship education course demonstration and educational device. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-9The present invention provides a technical solution: an innovation and entrepreneurship education course demonstration and education device, including a main body 1, the main body 1 including a machine base 11, a projector 14 fixedly installed on the upper surface of the machine base 11, a camera 13 fixedly installed on the machine base 11, a display screen 12 fixedly installed on the machine base 11, and an image display mechanism 2 set inside the machine base 11. Image display unit 2 includes image adding unit 21, which is located inside machine 11. Image adding unit 21 is used to automatically add teaching images so as to display relevant innovation and entrepreneurship education content and cases during course demonstrations.

[0021] As a further limitation of the image display mechanism 2 of the present invention, the image adding unit 21 includes two conveyors 2102. Each conveyor 2102 is fixedly installed on the inner wall of the machine base 11. Several identical base frames 2104 are fixedly installed on the upper surface of each conveyor 2102. A reset shaft 2106 is rotatably connected to the inner wall of each base frame 2104. Two reset springs 2111 are fixedly installed on the outer surface of each reset shaft 2106. Each reset spring 2111 is fixedly installed on the inner wall of the base frame 2104. A fixing plate 2105 is fixedly installed on the outer surface of each reset shaft 2106. The outer surface of each fixing plate 2105 contacts the inner wall of the base frame 2104. Each base frame 2102... The inner wall of the base frame 2104 is threaded with adjusting screws 2107. Two adjusting screws 2107 have a drive motor 2108 fixedly mounted at the end furthest from the base frame 2104. A synchronous pulley 2109 is fixedly mounted on the outer surface of each adjusting screw 2107. A transmission belt 2110 is connected to the outer surfaces of every two synchronous pulleys 2109. A lifting frame 2103 is provided above both conveyors 2102. A dual-shaft independent motor 2114 is fixedly mounted on the inner top wall of the lifting frame 2103. A double-threaded screw 2115 is rotatably connected to the inner wall of the lifting frame 2103. A transmission gear 2113 is fixedly mounted on the outer surface of the double-threaded screw 2115 and on one output end of the dual-shaft independent motor 2114. The outer surface of the double-threaded lead screw 2115 is threaded with two matching nuts 2117. A lifting clamp 2112 is fixedly mounted on the outer surface of each nut 2117. The outer surface of each lifting clamp 2112 contacts the inner wall of the lifting frame 2103. A first pulley 2118 is fixedly mounted on the other output end of the dual-axis independent motor 2114. Two connecting belts 2119 are drivenly connected to the outer surface of the first pulley 2118. A second pulley 2123 is drivenly connected to the inner ring of each connecting belt 2119. A support shaft 2122 is fixedly mounted on the inner wall of each second pulley 2123. The outer surface of each support shaft 2122 is rotatably connected to the inner wall of the lifting frame 2103. Each of the outer surfaces is fixedly mounted with a bearing seat 2116. The right side of each bearing seat 2116 is in contact with the inner side wall of the machine base 11. Each support shaft 2122 is fixedly mounted with a lifting gear 2124 on its outer surface. Each lifting gear 2124 is meshed with a lifting rack 2120 on its outer surface. Each lifting rack 2120 is fixedly mounted on the inner wall of the machine base 11. By setting up an image adding unit 21, the automatic addition of teaching images can be realized. In specific operation, the teaching images to be displayed are placed on the display board 2101. Then, according to the order of the images, the display board 2101 is pushed into the space between two fixed clamps 2105 in sequence, so that educational images can be displayed according to their characteristic order and stage. Please see Figure 9Each bearing seat 2116 has two sliding guide plates 2121 inside. Each guide plate 2121 is fixedly installed on the inner wall of the machine base 11. The guide plates 2121 limit the bearing seat 2116, so that the bearing seat 2116 can remain stable during the lifting process and will not deviate or shake. This further ensures the stability of the lifting clamp 2112 during the lifting process. Please see Figure 3 Each pair of fixed clamps 2105 has a display board 2101 on one side that is close to each other. The bottom surface of each display board 2101 is in contact with the inner wall of the machine 11. Through the display board 2101, different teaching pictures can be classified and placed, which facilitates automatic addition and display later. Before the educational demonstration, the pictures are stored in order in advance.

[0022] The specific implementation of this embodiment is as follows: When using physical images for educational demonstrations, the physical images can be pre-mounted on the display board 2101 and pushed into the machine 11 in a specific order. When the display board 2101 is inside the fixing clamp 2105, the fixing clamp 2105 fixes the display board 2101. The position of the fixing clamp 2105 can be determined by starting the drive motor 2108. The drive motor 2108 drives the adjusting screw 2107 to rotate. Due to the synchronous pulley 2109 and... The transmission belt 2110 drives the adjusting screw 2107 to rotate synchronously, causing the base frame 2104 and the fixed clamping plate 2105 to move and clamp the display board 2101. When conveying the display board 2101, the conveyor 2102 is started. The conveyor 2102 moves the fixed clamping plate 2105 and the display board 2101 as a whole a specific length, moving the display board 2101 under the lifting clamping plate 2112. When it is necessary to clamp the display board 2101 for subsequent operations, it can... One shaft of the dual-axis independent motor 2114 is activated, which drives the second pulley 2123 to rotate via the first pulley 2118 and the connecting belt 2119. The second pulley 2123 drives the support shaft 2122 to rotate. Due to the meshing of the lifting gear 2124 and the lifting rack 2120, the bearing seat 2116 and the lifting frame 2103 rise or fall along the lifting rack 2120, thereby driving the lifting clamp 2112 to rise and fall synchronously. When the lifting clamp 2112 falls to the same height as the display panel 2101... At this time, the other shaft of the dual-axis independent motor 2114 starts, driving the double-threaded screw 2115 to rotate through the transmission gear 2113. The rotation of the double-threaded screw 2115 causes the matching nut 2117 to drive the lifting clamp 2112 to move towards each other until the lifting clamp 2112 clamps the display plate 2101. The lifting clamp 2112 then continues to rise, fixing the clamp 2105 away from the display plate 2101, while the lifting clamp 2112 lifts the display plate 2101 onto the conveying path of the image display unit 22.

[0023] Example 2: Please refer to Figures 1-3 , Figure 7 and Figures 10-12 The present invention provides a technical solution: an innovation and entrepreneurship education course demonstration device. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The image display mechanism 2 also includes an image display unit 22, which is located inside the machine 11. The image display unit 22 is used to display pre-added teaching images during course demonstrations, so that the audience can intuitively understand the content and cases of innovation and entrepreneurship education.

[0024] As a further definition of the image display mechanism 2 of the present invention, the image display unit 22 includes a displacement frame 2202. The outer surface of the displacement frame 2202 is slidably connected to the interior of the machine base 11. A housing 2204 is fixedly installed on the side of the displacement frame 2202 away from the display panel 2101. A plurality of identical conveying rollers 2203 are rotatably connected to the inner wall of the housing 2204. A synchronous gear 2207 is fixedly installed on the outer surface of each conveying roller 2203. An idler gear 2206 is meshed on the outer surfaces of every two synchronous gears 2207. The outer surface of each idler gear 2206 is rotatably connected to the inner wall of the housing 2204. A servo motor 2205 is fixedly installed at the front end of one of the conveying rollers 2203. The servo motor 2205 is fixedly installed on the housing 2204. A linear slide rail 2209 is fixedly installed on the inner wall of the machine base 11. Two lifting blocks 2208 are slidably connected to the outer surface of the linear slide rail 2209. Each lifting block 2208... Display shells 2210 are fixedly installed on the side away from the linear slide rail 2209. Each display shell 2210 has a conveyor belt 2211 inside, and the inner ring of each conveyor belt 2211 is connected to a belt shaft 2213. The outer surfaces of the four belt shafts 2213 are fixedly installed with reverse gears 2214, and the upper surfaces of two belt shafts 2213 are fixedly installed with drive motors 2212. The bottom surface of each drive motor 2212 is fixedly connected to the upper surface of the display shell 2210. By setting up the image display unit 22, the images can be displayed sequentially in the display shell 2210 according to the image addition unit 21, so as to achieve the purpose of automatic display of teaching images. Furthermore, the vertical rotation of the display shell 2210 can also display images at different stages, thereby greatly enhancing the viewing experience of the audience and allowing the audience to more intuitively understand the various stages and interrelationships of innovation and entrepreneurship education. Please see Figure 2 A transparent plate 2201 is fixedly installed on the inner wall of the machine 11. The transparent plate 2201 is located in front of the display shell 2210. Through the transparent plate 2201, the teaching pictures displayed inside the display shell 2210 can be observed intuitively, so that the audience can clearly see the content and cases of innovation and entrepreneurship education.

[0025] The specific implementation of this embodiment is as follows: After the display board 2101 is moved to a specific position by the image adding unit 21, the displacement frame 2202 pushes the conveying rollers 2203 under the display board 2101, releases the lifting clamp 2112, and then starts the servo motor 2205. The servo motor 2205 drives the conveying rollers 2203 to rotate. Due to the meshing of the synchronous gear 2207 and the idler gear 2206, all the conveying rollers 2203 rotate synchronously, conveying the teaching images on the display board 2101 into the display shell 2210. At this time, the drive motor 2212 is started, and the drive motor 2212 drives the belt shaft 2213 to rotate. Due to the reverse gear 2214... The meshing action causes all shafts 2213 to rotate synchronously, driving the conveyor belt 2211 to sequentially transport the teaching pictures into the display shell 2210 for display. Viewers can clearly observe the teaching pictures displayed inside the display shell 2210 through the transparent panel 2201, thus gaining a more intuitive understanding of the various stages, sequences, and interrelationships of innovation and entrepreneurship education. When it is necessary to display teaching pictures from different stages, the lifting block 2208 can be controlled to slide up and down along the linear slide rail 2209 to expose another display shell 2210. Following the above picture transport steps, the pictures are moved into the display shell 2210 for display, thereby displaying teaching pictures from different stages.
