Description

Technical Field

[0001] This utility model relates to the field of experimental demonstration platform technology, and more specifically to an intelligent experimental demonstration platform. Background Technology

[0002] In the field of education, experimental demonstrations are an important means to help students understand abstract knowledge and master experimental skills. With the continuous advancement of educational informatization, recording and displaying experimental processes in real time, as well as combining them with interactive teaching using smart devices such as tablets, has become a key requirement for improving teaching quality and efficiency.

[0003] However, existing experimental demonstration equipment on the market currently falls short in meeting these needs, specifically in the following aspects: 1. Traditional document scanners or assessment cameras have significant limitations in experimental demonstration scenarios. These devices typically use fixed-point shooting, meaning that once installed, their shooting position and range are fixed and cannot be flexibly adjusted according to the needs of actual experimental operations. 2. The position adjustment of tablet stands on experimental demonstration tables is not flexible enough. 3. While common tablet stands on the market can hold tablets, they generally lack charging functionality or offer inconvenient charging methods. The length of the charging cable limits the range of movement of the tablet, preventing teachers from flexibly adjusting its position as needed during teaching.

[0004] In summary, existing experimental demonstration equipment has many problems that urgently need to be solved in terms of experimental shooting, stand position adjustment, and tablet charging, and cannot meet the requirements of modern education and teaching for flexibility, convenience, and efficiency. Utility Model Content

[0005] This utility model provides an intelligent experimental demonstration platform, which solves the following technical problems: fixed experimental shooting position, inconvenient adjustment of tablet stand position, and inconvenience of charging tablet in existing experimental demonstration equipment.

[0006] An intelligent experimental demonstration stand includes an experimental demonstration stand with a hollowed-out rear center, an experimental tabletop fixed to the upper end of the experimental demonstration stand, and a slide rail plate support module slidably connected to the experimental tabletop. The experimental tabletop and the slide rail plate support module are electrically connected so that a tablet computer placed on the slide rail plate support module can realize the charging function. An experimental shooting module is detachably connected to the front side of the experimental tabletop.

[0007] The slide rail plate support module includes a plate support that is inclinedly fixed to a slide base. A transverse electric slide rail is installed on the rear side of the experimental table. A rib rod that is slidably connected to the rear side of the slide base is fixed to the transverse electric slide rail. A conductive sheet is installed on the rib rod.

[0008] A USB charging port is installed on one side of the slide.

[0009] The experimental shooting module includes a fixed base with a clamping groove at the lower end. The fixed base is inserted into the experimental table through the clamping groove and fixed to the experimental table with screws. The fixed base has a storage groove, and a fixed shaft is installed in the storage groove. A camera rocker arm that can be stored in the storage groove is rotatably connected to the fixed shaft. A spherical rotating head is rotatably connected to the upper end of the camera rocker arm, and a camera is fixed to the upper end of the spherical rotating head.

[0010] The front side of the storage slot is provided with a track, and a slider that can slide within the track is fixed to the fixed shaft by screws.

[0011] One end of the mounting base is equipped with multiple five-hole sockets and a switch for controlling the five-hole sockets.

[0012] A four-hole low-voltage socket is installed at one end of the mounting base.

[0013] A rotary touch screen controller is installed at one end of the mounting base.

[0014] A mouse tray is installed on one side of the tablet holder.

[0015] The front of the experimental demonstration stand is slidably connected to multiple drawers with handles.

[0016] The beneficial effects of this utility model are:

[0017] 1. The position of the experimental shooting module is adjustable, which can achieve a larger shooting range.

[0018] 2. The sliding plate support module can be adjusted laterally at any time according to the changes in the teacher's lecturing position and the actual needs in the teaching process, providing greater convenience for teaching.

Detailed Implementation

[0033] See Figures 1 to 11 The diagram shows an embodiment of the demonstration stand according to the present invention that facilitates photography and use of the teaching tablet computer;

[0034] An intelligent experimental demonstration stand includes an experimental demonstration stand 1 with a hollowed-out rear center, an experimental table 4 fixedly connected to the upper end of the experimental demonstration stand 1, and a slide rail plate bracket module 3 slidably connected to the experimental table 4. The experimental table 4 and the slide rail plate bracket module 3 are electrically connected so that a tablet computer placed on the slide rail plate bracket module 3 can realize the charging function. An experimental shooting module 2 is detachably connected to the front side of the experimental table 4.

[0035] Experimental demonstration table 1 is used when the teacher conducts experiments that the entire class can view, such as... Figure 4As shown, the experimental shooting module 2 can be used as a camera or document scanner during evaluation. Traditional document scanners or evaluation cameras are fixed-point cameras, while the experimental shooting module 2 in this application is detachably connected to the experimental table 4. During installation, the position of the experimental shooting module 2 on the experimental table 4 can be flexibly adjusted, allowing for a wider shooting range. Figure 5 As shown.

[0036] The sliding plate holder module 3 can hold a tablet computer used by teachers for teaching. In actual teaching, teachers may explain and demonstrate experiments in different areas of the experimental table 4. If the sliding plate holder module 3 for placing the tablet computer is fixed in position, teachers may need to frequently move their bodies or adjust their viewing angle to see the screen content clearly. This not only increases the burden on teachers but may also distract students, reduce teaching interactivity and convenience, and is not conducive to the development of efficient teaching activities.

[0037] In this application, the slide rail flat plate support module 3 can slide laterally on the experimental tabletop 4, thereby allowing for flexible adjustment of the position of the slide rail flat plate support module 3. This enables the slide rail flat plate support module 3, which holds the flat plate, to be adjusted laterally according to changes in the teacher's lecturing position and actual needs during the teaching process, providing greater convenience for teaching. (See reference...) Figure 4 and 5 The position of the middle slide rail flat plate support module 3 changes.

[0038] Furthermore, when conducting laboratory work, teachers can slide the sliding plate support module 3 to one side of the experimental tabletop 4, and when in use, slide it to the center of the experimental tabletop 4. This provides convenience for teachers.

[0039] Furthermore, with the widespread use of tablet computers in education, battery life has become a significant factor restricting the continuity and convenience of teaching. Since the power supply in conventional teacher demonstration tables is located in the right-hand drawer of the lectern, teachers would need a cable longer than one meter to connect it, which is extremely inconvenient.

[0040] The length of the charging cable limits the range of movement of the tablet computer, preventing teachers from flexibly adjusting its position during teaching to achieve better teaching demonstrations and interactive effects. However, the sliding tablet stand module 3 in this application provides charging functionality when the tablet needs charging, allowing the tablet to be charged at any time without being restricted by the fixed length of the charging cable.

[0041] Secondly, the sliding tablet stand module 3 can also wirelessly charge the tablet, thus enabling teaching while charging.

[0042] Furthermore, by using the experimental shooting module 2 to record and display the experimental process in real time, and to conduct interactive teaching in conjunction with smart devices such as tablets, the quality and efficiency of teaching can be improved.

[0043] The front of the experimental demonstration table 1 is slidably connected to multiple drawers with handles, which facilitates the storage of teaching aids or teaching materials.

[0044] See Figure 2 The diagram shows an embodiment of the present invention in which a tablet computer can slide and charge freely without being restricted by the position of the charging port;

[0045] The slide rail flat panel support module 3 includes a flat panel support 302 that is tilted and fixed to a slide block 305. The tilted flat panel support 302 causes the placed flat panel to form a certain tilt angle, making it easier for teachers to view and operate the flat panel. A stop is fixed at the connection between the flat panel support 302 and the slide block 305 to limit the placement of the flat panel and prevent it from sliding down the tilt angle of the flat panel support 302. Furthermore, the flat panel support 302, the slide block 305, and the stop can be integrally molded.

[0046] A transverse electric slide rail 301 is installed on the rear side of the experimental table 4. A rib that is slidably connected to the rear side of the slide block 305 is fixedly connected to the transverse electric slide rail 301. The cross-sectional shape of the transverse electric slide rail 301 and the rib that cooperates with the transverse electric slide rail 301 can be in the form of a dovetail groove and a dovetail block, which can limit the slide block 305 and make it slide stably along the transverse electric slide rail 301, preventing the slide block 305 from detaching from the transverse electric slide rail 301. Limiting blocks that limit the slide block 305 are fixed to both sides of the transverse electric slide rail 301 by screws to prevent the slide block 305 from slipping out of its travel range during sliding.

[0047] A conductive plate is mounted on the prism; a USB charging port 303 is mounted on one side of the slide 305, and the USB charging port 303 contacts the conductive plate on the slide. After the prism with the conductive plate on the slide 305 is inserted into the horizontal power slide rail 301, it can obtain power from the horizontal power slide rail 301, thus enabling the tablet computer to be charged by the charging cable plugged into the USB charging port 303. Therefore, the tablet computer can slide and charge freely without being restricted by the position of the charging port.

[0048] The surface of the tablet bracket 302 is equipped with a main charging panel 306 and a secondary charging panel 304. For example... Figure 2 As shown. Both the main charging panel 306 and the auxiliary charging panel 304 are electrically connected to the slide block 305 and the slide rail 301 via power cords, thereby obtaining power from the slide rail 301.

[0049] The main charging panel 306 is used to place a tablet computer, and the secondary charging panel 304 is used to place a mobile phone, enabling wireless charging for multiple devices.

[0050] Both the main charging panel 306 and the secondary charging panel 304 contain transmitting coils. When alternating current passes through the transmitting coils, an alternating magnetic field is generated. When a tablet or phone is placed on the main charging panel 306 and the secondary charging panel 304, the coils inside the main charging panel 306 and the secondary charging panel 304 are placed in this alternating magnetic field, thereby generating an induced current to charge the battery inside the tablet or phone. This is similar to existing wireless charging technologies.

[0051] Furthermore, a stylus for controlling the tablet can also be placed on the secondary charging panel 304. The bezel also prevents the stylus from falling out.

[0052] A non-slip rubber layer can be glued to the part of the tablet holder 302 used to place the tablet. This increases the friction between the tablet and the tablet holder 302, preventing the tablet from shifting on the tablet holder 302 when it slides laterally.

[0053] See Figure 3 The diagram shows an embodiment of the increased shooting range according to the present invention;

[0054] The experimental shooting module 2 includes a fixed base 211 with a clamping groove 201 at the lower end. The fixed base 211 is inserted into the experimental table 4 through the clamping groove 201 and fixed to the experimental table 4 with screws. The fixed base 211 has a storage groove 212. A fixed shaft 202 is installed in the storage groove 212. A camera rocker arm 203 that can be stored in the storage groove 212 is rotatably connected to the fixed shaft 202. A spherical rotating head 204 is rotatably connected to the upper end of the camera rocker arm 203. A camera 205 is fixedly connected to the upper end of the spherical rotating head 204.

[0055] The mounting base 211 can slide on the front side of the experimental table 4 through the clamping groove 201, thereby adjusting the installation position of 211 and installing the mounting base 211 on the experimental table 4 at a suitable position by screws.

[0056] Under normal conditions, the camera jib arm 203, the spherical rotating head 204, and the camera 205 are horizontal and stored in the storage slot 212. This not only effectively avoids the problem of the camera occupying space when not recording, but also protects the spherical rotating head 204.

[0057] When the camera 205 is needed, manually rotate the camera arm 203 upward to a vertical position. The camera 205 is in a high position and can be used as a document camera or an evaluation camera for shooting. The instrument that controls the rotation of the camera 205 controls the spherical rotating head 204 to rotate and shoot within the camera arm 203, making the shooting range wider.

[0058] The 205 camera, with adjustable angle and position, can capture key details of the experiment comprehensively and clearly, increase the shooting range, and record the entire experimental process, thereby improving teaching effectiveness and providing great assistance for subsequent evaluation and analysis.

[0059] A rubber ring is bonded to the rotatable connection between the camera rocker arm 203 and the fixed shaft 202. When adjusting the angle of the camera rocker arm 203, the rubber ring between the camera rocker arm 203 and the fixed shaft 202 will provide a certain resistance. It is necessary to overcome a certain frictional resistance to rotate the camera rocker arm 203. After the angle of the camera rocker arm 203 stops, it will remain at the current angle, thereby fixing the angle of the camera 205.

[0060] Furthermore, a track 206 is provided on the front side of the storage groove 212, and a slider that can slide within the track 206 is fixed to the fixed shaft 202 by screws; the cross-sectional shape of the track 206 and the slider can also be matched with the shape of a dovetail groove and a dovetail block, thereby limiting the sliding trajectory of the fixed shaft 202, so that it can slide stably along the track 206 and prevent it from disengaging from the track 206.

[0061] The slider can slide laterally on the track 206, which further changes the lateral position of the camera 205, increases the shooting range of the camera 205, and makes it easier to slide the camera 205 to different positions for observation and shooting from more perspectives.

[0062] A rubber pad is bonded to the contact point between the slider and the track 206. The rubber pad also increases the friction between the slider and the track 206. As a result, when the slider is slid, the rubber pad will provide a certain resistance. It is necessary to overcome a certain frictional resistance to slide the slider and fix the shaft 202. Therefore, when the vertical position of the camera rocker arm 203 is adjusted, it will remain in the current position, thereby fixing the horizontal position of the camera 205.

[0063] Furthermore, one end of the mounting base 211 is equipped with multiple five-hole sockets 207 and a switch 208 for controlling the five-hole sockets 207. One end of the mounting base 211 is equipped with a four-hole low-voltage socket 209. A rotary touchscreen controller 210 is also installed at one end of the mounting base 211 to control the voltage of the four-hole low-voltage socket 209, thereby changing the current output strength of the four-hole low-voltage socket 209. This can be used for specific equipment using low voltage and for experiments. Both the five-hole sockets 207 and the four-hole low-voltage socket 209 are connected to an external power source via power cords.
