Description

Technical Field

[0001] This invention relates to the technical fields of educational tools, laboratory instruments and equipment, and in particular to a multifunctional educational laboratory platform. Background Technology

[0002] Currently, laboratory instruments and equipment used in education or experiments are developing towards multi-functionality and intelligence. For example, prior art document CN114505111B discloses a multi-functional mobile laboratory platform. This platform includes a cleaning tank, a lifting cabinet, drawers, complex transmission components (for extending pulleys, locking drawers, and retracting the lifting cabinet), and a flip-up extension plate. The flip-up extension plate is located on the side of the main operating table, used to expand the tabletop area. Another example is prior art document CN220162386U, which discloses an anti-static workbench. This anti-static workbench has an anti-static tabletop and an anti-static workbench with adjustable upper extension plate angle and height via electrically controlled struts. These prior art documents only consider the anti-static design of the experimental platform tabletop, the expansion of the main operating table's tabletop area, the lifting design of the tabletop, and the parallel movement design of the entire experimental platform, without addressing how the experimental platform's tabletop itself adapts to different experimental types and meets issues such as high-strength load-bearing capacity, deformation detection, vibration reduction, and anti-static properties.

[0003] In summary, existing educational laboratory platforms suffer from limitations such as the platform surface being unsuitable for different types of experiments and failing to meet performance requirements for high-strength load-bearing capacity, deformation detection, vibration reduction, and anti-static properties. Summary of the Invention

[0004] The purpose of this invention is to at least partially address the shortcomings of the prior art and provide a multifunctional educational laboratory platform that allows the platform surface to adapt to different types of experiments and meet performance requirements such as high strength load-bearing capacity, deformation detection, shock absorption, and anti-static properties.

[0005] The multifunctional educational laboratory platform provided by this invention includes: The experimental tabletop is movably mounted on the top of the platform support. The experimental tabletop includes a load-bearing panel and an antistatic polymer panel, which are located on two opposite sides of the experimental tabletop. The load-bearing panel is used for load-bearing experiments, and the antistatic polymer panel is used to support experiments that require antistatic properties. A tabletop controller, installed on one side of the platform support, is used to generate and send a tabletop flipping control signal based on the experiment type selected by the experiment user. A deformation monitoring sensor is installed on the load-bearing panel and communicates with the table controller. It is used to monitor the table deformation of the load-bearing panel during the load-bearing experiment and transmit the monitored table deformation to the table controller for processing to prevent abnormal deformation of the load-bearing panel from damaging the antistatic polymer panel. A tabletop flipping mechanism is installed on one side of the platform support and communicates with the tabletop controller. After the tabletop flipping mechanism is rotatably connected to the experimental tabletop, when it receives the flipping control signal sent by the tabletop controller, it controls the experimental tabletop to flip and switch between the load-bearing panel and the antistatic polymer panel.

[0006] Furthermore, the tabletop controller is an integrated display and control terminal with a touch screen, which displays an experiment type selection control when powered on; the experiment user initiates an experiment type selection command through the experiment type selection control.

[0007] Furthermore, the load-bearing panel includes a load-bearing platform and a load-bearing structure; the load-bearing structure is located at the bottom of the load-bearing platform and is integrally formed with the load-bearing platform or separately disposed therefrom.

[0008] Furthermore, the load-bearing structure consists of multiple independent load-bearing parts, with a hollow area between adjacent load-bearing parts. Each hollow area is equipped with at least one of the table surface deformation monitoring sensors. Each table surface deformation monitoring sensor transmits the table surface deformation of the load-bearing panel monitored during the load test to the integrated display and control terminal for processing and display.

[0009] Furthermore, the load-bearing panel also includes a shock-absorbing layer located at the bottom of the load-bearing structure, which separates the antistatic polymer panel from the load-bearing structure to reduce the vibration transmitted from the load-bearing panel to the antistatic polymer panel during the load-bearing test.

[0010] Furthermore, the antistatic polymer panel includes a positioning layer, an adhesive layer, and a polymer panel; the positioning layer is connected to the shock-absorbing layer and is bonded and fixed to the polymer panel through the adhesive layer.

[0011] Furthermore, the positioning layer includes a plurality of positioning portions spaced apart, and the adhesive layer is formed on each positioning portion at high temperature and the polymer panel is bonded and fixed to each positioning portion during the forming process.

[0012] Furthermore, the tabletop flipping mechanism includes a retractable flipping control arm. In the experimental state, the retractable flipping control arm retracts and resets under the experimental tabletop. After being pulled out from under the experimental tabletop and rotatably connected to the experimental tabletop, the retractable flipping control arm rotates according to the tabletop flipping control signal received from the tabletop controller, thereby controlling the experimental tabletop to flip and switch between the load-bearing panel and the antistatic polymer panel.

[0013] Furthermore, the retractable flip control arm includes a retractable central support arm and a retractable rotation control arm. The experimental platform and the retractable flip control arm are respectively provided with a platform central support hole and a platform rotation control mating hole at the position where they are rotatably connected. In the experimental state, both the retractable central support arm and the retractable rotation control arm are retracted and reset below the experimental platform.

[0014] Furthermore, after the retractable center support arm and the retractable rotary control arm are pulled out from under the experimental table surface, the retractable center support arm is inserted into the center support hole of the table surface and the retractable rotary control arm is inserted into the rotation control mating hole of the table surface, thus completing the rotational connection between the retractable flip control arm and the experimental table surface. The retractable rotary control arm is used to receive the table surface flip control signal sent by the table surface controller and rotate according to the received table surface flip control signal, controlling the experimental table surface to flip and switch between the load-bearing panel and the antistatic polymer panel.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The multifunctional educational laboratory platform provided by this invention includes an experimental tabletop, a tabletop controller, a deformation monitoring sensor, and a tabletop flipping mechanism. The experimental tabletop is movably mounted on the top of a platform support. The tabletop includes a load-bearing panel and an anti-static polymer panel, located on two opposite sides of the tabletop. The load-bearing panel is used for load-bearing experiments, and the anti-static polymer panel supports experiments requiring anti-static properties. The tabletop controller is mounted on one side of the platform support and generates a tabletop flipping control signal based on the experiment type selection command initiated by the user. The deformation monitoring sensor... A monitoring sensor is installed on the load-bearing panel and communicates with the platform controller. It monitors the deformation of the load-bearing panel during load-bearing experiments and transmits the detected deformation to the platform controller for processing, preventing abnormal deformation of the load-bearing panel from damaging the antistatic polymer panel. A platform flipping mechanism is installed on one side of the platform support and communicates with the platform controller. After the platform flipping mechanism is rotatably connected to the experimental platform, upon receiving the flipping control signal from the platform controller, it controls the experimental platform to flip and switch between the load-bearing panel and the antistatic polymer panel. This invention, by setting up a double-sided flipable experimental platform with a load-bearing panel and an antistatic polymer panel, and integrating a platform controller, deformation monitoring sensor, and platform flipping mechanism, enables a single experimental platform to intelligently and quickly switch between different experimental needs (high-intensity load-bearing experiments or antistatic sensitive experiments). This improves the efficiency of experimental preparation and the utilization rate of platform functions, effectively solving the technical problem of existing educational laboratory platform platforms having limited functionality and being unable to adapt to diverse experimental types. Moreover, the deformation monitoring sensor can monitor the deformation of the platform during load tests in real time. The data is processed by the platform controller, which can prevent damage to the anti-static polymer panel caused by abnormal deformation of the load-bearing panel due to overload, thus improving the safety and reliability of the platform.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar methods or methods having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5This invention proposes a multifunctional educational laboratory platform, including an experimental tabletop 100, a tabletop controller 300, a deformation monitoring sensor 400, and a tabletop flipping mechanism 500. The experimental tabletop 100 is movably mounted on the top of a platform support 200. The experimental tabletop 100 includes a load-bearing panel 101 and an antistatic polymer panel 102, located on two opposite sides of the experimental tabletop 100. The load-bearing panel 101 is used for load-bearing experiments, and the antistatic polymer panel 102 is used to support experiments requiring antistatic properties. The tabletop controller 300 is mounted on one side of the platform support 200 and is used to generate and issue a tabletop flipping control signal based on the experiment type selection command initiated by the experiment user. The deformation monitoring sensor 400 is disposed on the load-bearing panel 101 and communicates with the platform controller 300. It is used to monitor the deformation of the load-bearing panel 101 during the load-bearing experiment and transmits the monitored deformation to the platform controller 300 for processing to prevent abnormal deformation of the load-bearing panel 101 from damaging the antistatic polymer panel 102. The platform flipping mechanism 500 is installed on one side of the platform support 200 and communicates with the platform controller 300. After the platform flipping mechanism 500 is rotatably connected to the experimental platform 100, when it receives the flipping control signal sent by the platform controller 300, it controls the experimental platform 100 to flip and switch between the load-bearing panel 101 and the antistatic polymer panel 102. This invention, by setting up a double-sided reversible experimental platform 100 with a load-bearing panel 101 and an antistatic polymer panel 102, and integrating a platform controller 300, a deformation monitoring sensor 400, and a platform flipping mechanism 500, enables a single experimental platform 100 to intelligently and rapidly switch physical modes according to different experimental needs (high-intensity load-bearing experiments or antistatic sensitive experiments). This improves the efficiency of experimental preparation and the utilization rate of platform functions, effectively solving the technical problem of existing educational laboratory platforms having limited platform functions and being unable to adapt to diverse experimental types. Moreover, the deformation monitoring sensor 400 can monitor the platform deformation in real time during load-bearing experiments. Through data processing by the platform controller 300, damage to the antistatic polymer panel 102 caused by abnormal deformation of the load-bearing panel 101 due to overload can be prevented, thus improving the safety and reliability of the platform.

[0023] In some preferred embodiments, the platform controller 300 is a display and control integrated terminal with a touch screen. When powered on, the display and control integrated terminal displays an experiment type selection control; the experiment user initiates an experiment type selection command through the experiment type selection control. The display and control integrated terminal with the touch screen provides an intuitive and integrated human-machine interface. By graphically displaying the experiment type selection control on the screen, users can directly and accurately initiate experiment type selection commands through simple touch operations without relying on additional physical buttons or complex instructions, improving the convenience and experience of user operation. This display and control integrated terminal can be an industrial touch screen all-in-one machine, installed on the platform bracket 200 in a convenient location for operation and observation. After the terminal is powered on, its operating system can run dedicated control software. The software interface displays selection controls for load-bearing experiment mode and anti-static experiment mode. The user directly clicks the corresponding control, and the software generates the corresponding experiment type selection command data packet, which is sent to the main control unit through the terminal's internal communication module (such as a serial port or Ethernet), thereby triggering the subsequent flipping control process.

[0024] In some preferred embodiments, the load-bearing panel 101 includes a load-bearing surface 1010 and a load-bearing structure 1011; the load-bearing structure 1011 is located at the bottom of the load-bearing surface 1010 and is integrally formed with or separately from the load-bearing surface 1010. The dedicated load-bearing structure 1011 can concentrate the main load-bearing stress on this structure, thereby allowing the load-bearing surface 1010 to be made of materials that prioritize surface smoothness and wear resistance rather than absolute strength. Specifically, the load-bearing structure 1011 and the load-bearing surface 1010 can be integrally formed or separately. For example, the load-bearing surface 1010 can be a composite material panel integrally formed with the load-bearing surface 1010. For example, the load-bearing structure 1011 can be an independent frame component, detachably fixed to the upper load-bearing surface 1010 by bolts or clips.

[0025] In some preferred embodiments, the load-bearing structure 1011 comprises multiple independent load-bearing parts 1012, with hollow areas 1015 between adjacent load-bearing parts 1012. Each hollow area 1015 contains at least one of the aforementioned tabletop deformation monitoring sensors 400. Each tabletop deformation monitoring sensor 400 transmits the tabletop deformation of the load-bearing panel 101 monitored during the load-bearing experiment to the integrated display and control terminal for processing and display. The load-bearing structure 1011, composed of multiple independent load-bearing parts 1012, and the hollow areas 1015 between adjacent load-bearing parts 1012 equipped with deformation monitoring sensors 400, enables refined and zoned monitoring of the deformation of the load-bearing panel 101. The independent load-bearing parts 1012 can divide the load-bearing panel 101 into multiple independent mechanical support units, making the monitoring data more direct and sensitive when deformation occurs in the area of ​​the load-bearing panel 101 corresponding to the hollow area 1015. The arrangement of multiple tabletop deformation monitoring sensors 400 can pinpoint the specific area where deformation occurs and aggregate the data to a display and control integrated terminal for visualization and display, providing users with more accurate status information and safety warnings for the load-bearing panel 101. In implementation, the load-bearing structure 1011 can be composed of multiple parallel strip-shaped or block-shaped independent load-bearing parts 1012, with uniform gaps between the load-bearing parts 1012 forming hollow areas 1015. At the center of each hollow area 1015, a deformation monitoring sensor 400 is installed, with its sensing part attached to or connected to the lower surface of the load-bearing panel 101. Each deformation monitoring sensor 400 transmits its monitored local deformation data to the display and control integrated terminal via an independent wireless module. The terminal software can receive and analyze the data from each sensor, displaying the real-time deformation of each monitoring point on the screen in digital or graphical form, and drawing an overall deformation cloud map of the tabletop.

[0026] In some preferred embodiments, the load-bearing panel 101 further includes a shock-absorbing layer 1014, which is located at the bottom of the load-bearing structure 1011, separating the antistatic polymer panel 102 from the load-bearing structure 1011 to reduce vibrations transmitted from the load-bearing panel 101 to the antistatic polymer panel 102 during load-bearing experiments. The shock-absorbing layer 1014, located at the bottom of the load-bearing structure 1011, can effectively absorb and buffer vibration energy transmitted from the load-bearing structure 1011 during load-bearing experiments (especially those involving impact or vibration), preventing or reducing vibration transmission to the antistatic polymer panel 102 on the other side, protecting the structural integrity of the antistatic polymer panel 102, and preventing it from cracking or delaminating due to long-term vibration. The damping layer 1014 can be made of a high-damping elastic material, such as a rubber sheet, silicone pad, polyurethane foam, or a special composite material vibration isolation pad. Specifically, the damping layer 1014 can be shaped to support the bottom contour of the load-bearing structure 1011. It can be fixed to the bottom of the load-bearing structure 1011 by means of adhesive bonding, mechanical pressing, or embedded installation, so that it completely covers the space between the load-bearing structure 1011 and the antistatic polymer panel 102, thereby playing a role in physical isolation and energy dissipation.

[0027] In some preferred embodiments, the antistatic polymer panel 102 includes a positioning layer 1020, an adhesive layer 1021, and a polymer panel 1022. The positioning layer 1020 connects to the shock-absorbing layer 1014 and is bonded and fixed to the polymer panel 1022 via the adhesive layer 1021. The inclusion of the positioning layer 1020, adhesive layer 1021, and polymer panel 1022 in the antistatic polymer panel 102 optimizes the assembly firmness and reliability of the antistatic polymer panel 102. The positioning layer 1020 provides a stable connection base with the shock-absorbing layer 1014; the adhesive layer 1021 ensures a firm and uniform bond between the polymer panel 1022 and the positioning layer 1020, preventing warping or detachment of the panel during use. The positioning layer 1020 can be made of metal or engineering plastic and can be fixed to the shock-absorbing layer 1014 by adhesive bonding, mechanical pressing, or embedding. The adhesive layer 1021 can be an adhesive (such as epoxy resin, acrylic glue, or hot melt adhesive) coated on the upper surface of the positioning layer 1020. The polymer panel 1022 is the working surface and can be made of antistatic PVC, acrylic, or composite material. After being connected to the uncured adhesive layer 1021, the fixation is completed after the adhesive layer 1021 cures.

[0028] In some preferred embodiments, the positioning layer 1020 includes a plurality of spaced-apart positioning portions 1023. The adhesive layer 1021 is formed on each positioning portion 1023 at high temperature, and the polymer panel 1022 is bonded and fixed to each positioning portion 1023 during the forming process. The positioning layer 1020, with its multiple spaced-apart positioning portions 1023, and the adhesive layer 1021 formed on each positioning portion 1023 at high temperature to bond the polymer panel 1022, can improve the uniformity, strength, and process controllability of the bond. The spaced-apart positioning portions 1023 can reduce the bonding area, lower internal stress caused by differences in the thermal expansion coefficients of the materials, and allow the adhesive material to flow and fill better at high temperatures. The high-temperature forming process allows the adhesive layer 1021 material (such as a hot melt adhesive film) to fully melt and wet the positioning portions 1023 and the polymer panel 1022, forming a strong chemical or physical bond, ensuring a firm and durable bond. In implementation, multiple metal bosses can form positioning parts 1023, which are arranged in an array to form positioning layers 1020, with gaps between the bosses. A solid hot melt adhesive film is pre-laid to cover all positioning parts 1023, and a polymer panel 1022 is placed on top of it. The whole assembly is then fed into a hot press. Under the set temperature and pressure, the hot melt adhesive film melts and mainly gathers and wraps around each positioning part 1023, forming individual adhesive pillars that tightly bond the polymer panel 1022 to each positioning part 1023.

[0029] In some preferred embodiments, the tabletop flipping mechanism 500 includes a retractable flipping control arm. In experimental conditions, the retractable flipping control arm retracts and resets beneath the experimental tabletop 100. After being pulled out from under the experimental tabletop 100 and rotatably connected to it, the retractable flipping control arm rotates according to a tabletop flipping control signal received from the tabletop controller 300, controlling the experimental tabletop 100 to flip between the load-bearing panel 101 and the antistatic polymer panel 102. The use of a retractable flipping control arm in the tabletop flipping mechanism 500 achieves compactness and automation. The retractable flipping control arm retracts and resets beneath the tabletop in experimental conditions, occupying no extra space and maintaining the cleanliness of the overall experimental platform and unobstructed access to the surrounding activity area. When flipping is required, the retractable flipping control arm can be manually pulled out and connected to the experimental tabletop 100 to perform the flipping action, improving space utilization.

[0030] In some preferred embodiments, the retractable flip control arm includes a retractable central support arm 5000 and a retractable rotary control arm 5001. A central support hole 103 and a rotary control fitting hole 104 are respectively provided at the position where the experimental platform 100 rotatably connects to the retractable flip control arm. Both the retractable central support arm 5000 and the retractable rotary control arm 5001 retract and reset below the experimental platform 100 during the experimental state. The retractable flip control arm includes a retractable central support arm 5000 and a retractable rotary control arm 5001, and the experimental platform 100 is provided with corresponding fitting holes, which can optimize the stability and control accuracy of the flipping process. The central support arm is inserted into the central support hole 103 of the platform, mainly bearing the weight of the platform during flipping and providing a rotational central axis to ensure smooth and wobbly flipping. The rotary control arm is inserted into the rotary control fitting hole and is responsible for providing rotational driving force. The two arms work together to achieve stable and reliable flipping control of the heavy platform, avoiding the torque deficiency or off-center load problems that may occur with single-point drive. In implementation, a central support hole (usually a smooth hole) and an eccentrically positioned rotary control mating hole (which can be an internal spline or a non-circular hole) can be machined at appropriate positions on the side of the experimental platform 100. The end of the telescopic central support arm 5000 can be designed as a smooth cylindrical shaft head, and the end of the telescopic rotary control arm 5001 can be designed as a drive shaft head that matches the shape of the mating hole. During the flipping preparation stage, both arms extend synchronously and are precisely inserted into their corresponding holes. After insertion, the drive motor of the rotary control arm operates, driving the rotary control arm to rotate the experimental platform 100 around the axis of the central support arm.

[0031] In some preferred embodiments, after the retractable center support arm 5000 and the retractable rotary control arm 5001 are pulled out from under the experimental tabletop 100, the retractable center support arm 5000 is inserted into the tabletop center support hole 103 and the retractable rotary control arm 5001 is inserted into the tabletop rotary control mating hole 104, completing the rotary connection between the retractable flip control arm and the experimental tabletop 100. The retractable rotary control arm 5001 is used to receive the tabletop flip control signal issued by the tabletop controller 300 and rotate according to the received tabletop flip control signal, controlling the experimental tabletop 100 to flip between the load-bearing panel 101 and the antistatic polymer panel 102. Specifically, when flipping is required, the two arms first extend and complete the physical connection (inserting into the corresponding holes), and then the rotary control arm receives the signal to execute the rotation drive, thereby ensuring the mechanical connection is secure first, followed by power transmission, improving the safety of the entire flipping process. During implementation, when the platform controller 300 issues a platform flipping control signal, the drive motor of the retractable rotary control arm 5001 rotates according to the signal. Through the engagement of the retractable rotary control arm 5001 with the mating holes, the entire experimental platform 100 is smoothly rotated 180 degrees around the axis of the central support arm, completing the platform switching. After flipping to the correct position, the motor stops, the two arms retract from their corresponding insertion holes, and retract and reset beneath the experimental platform 100, maintaining the neat appearance of the overall experimental platform and ensuring unobstructed access to the surrounding activity area.

[0032] The above is a description of the technical solution provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
