[0002] Physical electronics experiments are crucial for understanding basic concepts such as current, voltage, and resistance. By building circuits and adjusting component parameters, students can intuitively feel the changes in these basic physical quantities. This not only helps to consolidate theoretical knowledge but also lays a solid foundation for future electronic technology innovation.

[0003] In the study of physical electronics experiments, it is often necessary to use simulation devices to assist in the study of electronic experiments, so as to deepen students' impression of the key points of the experiments, improve students' learning interest, and the simulation devices can also verify physical electronics experiments.

[0004] Currently, in existing physical electronics experiments, when connecting electrical appliances and electroscopes, wires are required for connection.

[0029] To make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation mode of the present invention in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1-5 , the present invention provides a physical electronics experiment simulation device, including an experiment box 1. The top of the experiment box 1 is hinged with a box cover 2. In this embodiment, a hook 3 and a hanging rod 4 are respectively arranged on the experiment box 1 and the box cover 2 near the opening side. The hook 3 is rotatably connected to the outer wall of the experiment box 1, and the hook 3 is correspondingly hooked with the hanging rod 4. By rotating the hook 3, it can be turned over and hooked with the hanging rod 4, which is convenient for closing and fixing the experiment box 1.

[0031] An experiment area 5 is arranged at the center inside the experiment box 1, storage areas 6 are arranged on both sides of the experiment area 5, and a power supply compartment 7 is arranged near the opening of the experiment box 1. The power supply compartment 7 includes a plurality of battery racks 701, and the plurality of battery racks 701 are connected in series, which is convenient for supplying power to the experimental equipment in the experiment box 1.

[0032] Inside the experimental area 5, a positioning disk 8 is fixedly connected. Near the top of the inner wall of the positioning disk 8, a grid plate 9 is fixedly connected. Among them, partition labels corresponding to the grid plate 9 are set around the top of the positioning disk 8. By installing different electrical appliances at the positions corresponding to the labels on the positioning disk 8, it is convenient for the staff to connect the power supply paths at the corresponding positions according to the labels.

[0033] On the top of the grid plate 9, a fast socket for an electric meter 14 is provided. At both ends of the bottom of the fast socket for an electric meter 14, connecting rods 13 are fixedly connected.

[0034] In this embodiment, at one end of the top of the fast socket for an electric meter 14, a fixed wiring clip 141 is fixedly connected. At the other end of the top of the fast socket for an electric meter 14, a sliding wiring clip 142 is slidably connected. Inside the inner wall of the fast socket for an electric meter 14, a positioning post 143 is fixedly connected. A positioning groove 144 corresponding to the positioning post 143 is opened on the outside of the sliding wiring clip 142. The two connecting rods 13 are respectively electrically connected to the bottoms of the fixed wiring clip 141 and the sliding wiring clip 142 through wires. When installing and replacing an electrical checker, such as an ammeter or a voltmeter, it is directly inserted into the fast socket for an electric meter 14, so that the fixed wiring clip 141 and the sliding wiring clip 142 are correspondingly and quickly connected to the positive and negative wiring terminals of the electric meter, and there is no need to manually connect the wires.

[0035] In this embodiment, rubber sleeves are fixedly connected to the outer side walls of the two connecting rods 13. The rubber sleeves are arranged in a corrugated shape and play a role of anti-slip and limiting. After inserting them into the grid plate 9, through the friction force with the inner wall of the grid plate, it is convenient to prevent the connecting rods 13 from coming out and keep them in contact with the metal elastic pieces.

[0036] At the inner bottom of the positioning disk 8, a first electrical connector 10 and a second electrical connector 11 are fixedly connected. Two conductive sheets 12 are fixedly connected through the side of the positioning disk 8 close to the power supply bin 7.

[0037] The first electrical connector 10 includes a first motor 101. At the top of the driving shaft of the first motor 101, a first metal elastic piece 102 is fixedly connected. At the bottoms of both ends of the first metal elastic piece 102, first cut corners 103 are provided. The second electrical connector 11 includes a second motor 111. At the top of the driving shaft of the second motor 111, a second metal elastic piece 112 is fixedly connected. At the tops and bottoms of both ends of the second metal elastic piece 112, second cut corners 113 are provided.

[0038] Among them, the two conductive sheets 12 are respectively electrically connected to the two end electrodes of the power supply bin 7. Since in this embodiment, the ends of the circuits are all first metal elastic pieces 102, the other ends of the two conductive sheets 12 are correspondingly electrically connected to the first metal elastic pieces 102 in the positioning disk 8, and through the conductive sheets 12 at both ends, it is convenient to connect the circuits in the positioning disk 8 to the power supply bin 7.

[0039] In use, rotate the hook 3 off the hanging rod 4 to break the hooking relationship, open the experimental box 1, and take out the electric meter quick socket 14, knife switch, electrical appliance connection base, etc. from the storage area 6. The electric meter quick socket 14 is used to install electrical measuring instruments such as ammeters and voltmeters. The knife switch is used to control the current path. The electrical appliance connection base is used to install electrical appliances such as small light bulbs and resistors.

[0040] As Figure 4 shown, a number of first metal elastic pieces 102 and second metal elastic pieces 112 are provided at the bottom of the positioning disk 8. Each node of the grid plate 9 can be represented by the partition labels around the positioning disk 8, so that when different electrical appliances are inserted into the grid plate 9, the positions of the corresponding wiring rods 13 at their bottoms can be accurately understood, thus facilitating the accurate control of the start and stop of the first and second micro-motors.

[0041] The coordinated work between the first motor 101 and the second motor 111 can be realized through external PLC programming, which is the prior art and will not be elaborated here. For example, in this embodiment, as Figure 2 and Figure 4 shown, the electric meter quick socket 14 is located at the uppermost position of the positioning disk 8. After the wiring rod 13 at its bottom is inserted into the grid, it can contact the first metal elastic piece 102 and the second metal elastic piece 112 in the positioning disk 8. At this time, the positive and negative wiring rods 13 of the electric meter can be connected to the circuit.

[0042] An electric meter quick socket 14 is provided in this device, which is adapted to most electric meters on the current market. Taking the voltmeter as an example, the fixed wiring clip 141 is clamped and connected to its negative pole, and the two different range positive poles of the voltmeter corresponding to the sliding wiring clip 142 are directly inserted into it, so that it can be quickly adapted to the installation method of the grid plate 9 in this device. The whole connection process does not require wires, improving the installation efficiency.

[0043] In this embodiment, a number of groups of first metal elastic pieces 102 and second metal elastic pieces 112 are provided in the positioning disk 8. The specific installation positions can be specifically adjusted according to experimental needs. The first motor 101 and the second motor 111 are both fixed to the bottom of the positioning disk 8 by bolts and can be flexibly adjusted.

[0044] Although the present invention has been described above with reference to the embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in the present invention can be combined with each other in any way, and the reason for not exhaustively describing the situations of these combinations in this specification is only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
