Description

Technical Field

[0001] The utility model belongs to the technical field of electronic technology experimental equipment, and in particular relates to a building block type portable electronic technology experimental device. Background Art

[0002] Electronics experiments are an essential component of electronics education. There are two basic formats: one is online or computer simulation, where students conduct experiments on a computer. These experiments prevent students from interacting with actual electronic components and circuits, making them generally ineffective for most students. The other is in-person labs, where students must schedule their labs or make reservations to access the lab. While students can interact with actual objects, some simulated electronics experiments make it difficult to quickly retrieve experimental results, resulting in poor results. Conventional lab equipment is bulky and requires additional signal sources, oscilloscopes, and multimeters, making it difficult to carry out experiments on the go. Electronics lab benches or boxes are modular, making it easy for students to burn out components or modules due to improper operation. If a module breaks or has poor connections, it's difficult to detect them within a limited timeframe, impacting experimental efficiency. Furthermore, the power and signal cables of the modules require connectors, which can become disconnected or poorly connected due to frequent use or carelessness. All of these issues can lead to suboptimal results or even failure. Utility Model Content

DETAILED DESCRIPTION

[0040] The present invention will be further described below with reference to the accompanying drawings:

[0041] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0042] Based on the hardware of this electronic technology experimental equipment, experiments of different complexity levels such as basic experiments, unit design experiments, and system experiments can be completed:

[0043] (1) Basic experiments refer to verification experiments. The purpose is to learn basic verification methods and means, become familiar with the use of experimental teaching instruments and equipment, and understand the basic knowledge points in the course. The specific method is to select the corresponding component modules according to the contents of the experimental instruction manual, complete the circuit connection on the experimental board 200 of the present invention according to the circuit schematic diagram, and conduct tests to obtain correct experimental data and analyze them, stimulate students' desire to get hands-on, and initially cultivate students' sense of participation.

[0044] (2) Unit design experiments refer to comprehensive experiments. In this link, two experimental boards 200 or even more need to be combined. Students first complete the processing of some signals according to each function. They need to analyze and calculate some individual devices separately and then select the corresponding component modules. Then, they build the circuit according to the circuit schematic diagram and connect the experimental modules on the basis of correct signal output. While completing the experiment, they have a holistic understanding of the entire unit circuit based on the flow of signals. In this type of experiment, different experimental purposes are set for different functional modules, and each module completes the corresponding function. The construction and testing of the entire unit module are completed while ensuring that each functional module works normally.

[0045] (3) System experiment refers to a design experiment. In this type of experiment, the functions that the system should realize or the parameters of the required output signal are required, without involving specific experimental devices and processes. Select appropriate functional circuits and component modules by searching for information, analyzing and calculating. Let students independently design experimental circuits, formulate experimental plans, and complete the experimental process based on the knowledge they have learned. This type of experiment requires the collaboration of multiple members, and generally requires several experimental equipment to be cascaded to complete this type of experiment. The present invention adapts to the requirements of students of different levels, so that design experiments can be implemented. Improve students' hands-on ability and cultivate students' independent innovation ability

[0046] like Figure 1 The experimental steps are as follows:

[0047] Step 1: Determine the experimental plan according to the contents of the experimental instructions or design it yourself;

[0048] Step 2: Determine the circuit schematic according to the experimental plan;

[0049] Step 3: Open the experimental box 110 and select the component modules or integrated circuit modules used according to the experimental circuit schematic diagram, and build the circuit on the experimental board 200;

[0050] Step 4: Check the correctness of the experimental circuit. If there is no error, turn on the power switch 1292 to supply power and input the signal.

[0051] Step 5: Adjust component parameters to obtain satisfactory output signals and record data;

[0052] Step 6: Turn off the main power of the experimental box 110 and put the experimental board 200 and the device module back into the experimental box 110 .

[0053] like Figures 2 to 6 As shown, a building block type portable electronic technology experimental device includes a box body 100 and an experimental board 200. The box body 100 includes an experimental box 110 and a storage box 120, which are hinged to each other, and a plurality of first suction positions 111 are installed on one side of the experimental box 110; the experimental board 200 is adsorbed on the side of the experimental box 110 facing the storage box 120, and a plurality of magnetic mother seats 210 are installed on one side of the experimental board 200; wherein the experimental board 200 faces the side of the experimental box 110. An isolation column 201 is installed on one side, and a second attraction position 202 adapted to the first attraction position 111 is installed on the end of the isolation column 201 facing away from the experimental board 200; the storage box 120 defines a plurality of different storage areas 121 on the side facing the experimental box 110 for storing different electronic components, and each electronic component is installed with at least one magnetic male seat 220 on the side facing the experimental board 200; wherein, the magnetic male seat 220 is adapted to be connected with the magnetic female seat 210.

[0054] Optionally, a plurality of first locks 102 are provided on the outer wall of the experimental box 110 away from the storage box 120, and handles 101 are installed between the first locks 102; a second lock 103 is provided on the outer wall of the storage box 120 away from the experimental box 110, which is compatible with the first locks 102, and handles 101 are also installed between the second locks 103. In this way, through the mutual cooperation of the first locks 102 and the second locks 103, the experimental box 110 and the storage box 120 can be locked after they are closed, so that they are not easily displaced or separated after closing.

[0055] like Figure 3As shown, the magnetic nut 210 includes a base 211, a magnet 212, an insulator 213, and a first conductor 214. The base 211 has a mounting groove 2111 at one end and multiple grounding terminals 2112 at the edge of the other end. The magnet 212 is mounted within the mounting groove 2111, and an insulator 213 is mounted at the center of the magnet 212. The first conductor 214 is embedded within the insulator 213 and protrudes out of the base 211, located between the grounding terminals 2112. A connecting jack 2141 is provided at one end of the insulator 213. Thus, the insulator 213, which wraps around the outer wall of the first conductor 214, acts as an insulating barrier between the base 211 and the magnet 212, preventing the first conductor 214 from contacting the base 211 and / or the magnet 212 and causing a short circuit. In addition, the portion of the first conductor protruding from the base 211 and the grounding end 2112 are both connected and fixed to the experimental board 200 .

[0056] like Figure 4 As shown, the male magnetic socket 220 includes a base 211, a magnet 212, an insulator 213, and a second conductor 215. The male magnetic socket 220 shares some of the same structure as the female magnetic socket 210, and the magnet 212 of the male magnetic socket 220 has either an N or S pole, which mates with the magnet 212 on the female magnetic socket 210. Thus, the male magnetic socket 220 and the female magnetic socket 210 are connected by attraction due to the opposite poles of the magnet 212. Once connected, the second conductor 215 of the male magnetic socket 220 automatically connects to the first conductor 214 of the female magnetic socket 210, thereby improving operational convenience.

[0057] like Figure 3 and Figure 4 As shown, the end of the second conductor 215 facing the first conductor 214 is further provided with a connecting plug 2151 adapted to the connecting jack 2141. Thus, when the first conductor 214 and the second conductor 215 are connected, the connector of the second conductor 215 automatically embeds into the connecting jack 2141. This effectively improves the connection stability between the first conductor 214 and the second conductor 215.

[0058] like Figure 5 and Figure 6 As shown, the experiment board 200 includes a discrete component experiment board 230 and an integrated circuit experiment board 240, which are stacked one on top of the other. Isolation columns 201, identical to those used on the discrete component experiment board 230, are provided on the side of the integrated circuit experiment board 240 facing the discrete component experiment board 230. Thus, the isolation columns 201 prevent electrical short circuits from occurring when the discrete component experiment board 230 and the integrated circuit experiment board 240 are stacked and connected. Furthermore, the isolation columns 201 create a certain distance between the discrete component experiment board 230 and the integrated circuit experiment board 240, reducing signal interference and improving experimental accuracy.

[0059] Optionally, the isolation column 201 is adsorbed and connected to the second attraction position 202. In this way, a stable support effect can be formed between the separation component experiment board 230 and the integrated circuit experiment board 240 through the adsorption connection between the isolation column 201 and the second attraction position 202.

[0060] Optionally, the magnetic female socket 210 or the magnetic male socket 220 installed on the separation component experiment board 230 and the integrated circuit experiment board 240 can be connected using a wire 203.

[0061] like Figure 5 and Figure 6 As shown, the separation component experiment board 230 is provided with a three-port module placement area; the integrated circuit experiment board 240 is provided with an integrated circuit module placement area 231.

[0062] like Figures 7 to 18 As shown, the storage area 121 includes a connection line storage area 122, a transistor module storage area 123, a multi-port module storage area 124, a potentiometer module storage area 125, a capacitor module storage area 126, a resistor module storage area 127, and an instrument storage area 128, for storing corresponding electronic components. Thus, by meticulously dividing the space of the storage area 121, the storage accuracy of each electronic component can be effectively improved, effectively improving experimental efficiency and increasing space utilization.

[0063] It can be understood that the connecting wire storage area 122 is used to store connecting wires; the transistor module storage area 123 is used to store the transistor module 1231; the multi-port module storage area 124 is used to store the multi-port module 1241; the potentiometer module storage area 125 is used to store the potentiometer module 1251; the capacitor module storage area 126 is used to store the capacitor module 1261; the resistor module storage area 127 is used to store the resistor module 1271; and the instrument storage area 128 is used to store the instrument experiment board 1281.

[0064] Optionally, one end of the transistor module 1231 , the multi-port module 1241 , the potentiometer module 1251 , the capacitor module 1261 , the resistor module 1271 , and the instrument module is provided with a connection hole 1294 for connecting a magnetic female connector or a magnetic male connector.

[0065] Optionally, the multi-port module 1241 includes a two-port terminal block 1242, a three-port terminal block 1243, and an integrated circuit experiment module 1244, wherein the integrated circuit experiment module 1244 includes an 8-port magnetic integrated block base 1245, a 14-port magnetic integrated block base 1246, and a 16-port magnetic integrated block base 1247.

[0066] Optionally, an integrated circuit socket seat 1248 is provided in the middle of the 8-port magnetic integrated block base 1245 , the 14-port magnetic integrated block base 1246 , and the 16-port magnetic integrated block base 1247 .

[0067] like Figure 8 As shown, an instrumentation experiment board 1281 is placed in the instrumentation storage area 128, which integrates a main switch panel 1282, a battery level indicator panel 1283, a DC ammeter 1284, a signal generator 1285, an oscilloscope 1286, a digital tube and DP indicator 1287, a multi-way power supply area 1288, a line connection tester 1289, a DC voltmeter 1290, a manual / automatic pulse generator 1291, and all modules are provided with a power switch 1292. In this way, the integrated instrumentation experiment board not only effectively improves the experimental efficiency. At the same time, through the independent power switch 1292 provided on each module, each module can be individually controlled, so that the operator can flexibly choose to enable or disable the instrumentation according to the experimental needs.

[0068] like Figures 9 to 13 As shown, one side of each of these electronic components is equipped with a female magnetic receptacle 210 or a male magnetic receptacle 220 and a TP connector 1293. This allows for testing using an external lab box 200 or an instrumentation test board 1281, effectively improving the module's applicability and enabling the use of different connection methods based on experimental needs.

[0069] like Figures 19 to 21 As shown, a detachable magnetic hook needle 300 is also installed on one side of the electronic component, which is composed of a conductive sheet 301, an insulating sleeve 302, a sleeve 303, a metal rod 304, and a hook head 305. One end of the metal rod 304 is fixedly connected to the conductive sheet 301, and the other end is fixedly connected to the hook head 305. The outer wall of the conductive sheet 301 is wrapped with an insulating sleeve 302, the outer wall of the metal rod 304 is wrapped with a sleeve 303, and the hook head 305 protrudes from the sleeve 303. In this way, when setting up an experimental circuit and / or collecting model input, when connecting a test point to multiple test devices, a single magnetic hook needle 300 or a double magnetic hook needle 300 can be selected for connection, thereby achieving the purpose of improving the applicability of the connection.

[0070] The following is an example of a common emitter amplifier circuit experiment. Figure 22 It can be seen that a total of 12 modules are required, including resistors, capacitors, transistors and DC ammeters. The experimental modules of the present invention can be selected to form the circuit and conduct experiments through the onboard instrument panel. The 12 modules are as follows: Figure 16As shown, there are a total of 6 resistor modules, 3 capacitor modules, 1 potentiometer module, 1 transistor module and 1 DC ammeter module. The circuit can be built using a separate component experiment board of this experiment box and the 12 modules used in the schematic diagram. The distribution on the experiment board is as follows Figure 16 As shown. Figure 16 The red dotted line numbers in Figure 15 The red dotted line numbered component modules correspond to each other to achieve "building block" construction. The 12v power supply of the circuit is connected to the Vcc of the experimental board through two magnetic male connectors, as shown in the red solid line boxes 13 and 14; the ground wire is connected to the Gnd of the experimental board through the black solid line boxes 15, 16, 17 and 18; check that there are no errors and connect the Vcc and Gnd of the experimental board to the +12V power supply and ground in the instrument experimental board respectively to complete the circuit power supply; the orange box In is connected to the signal source module in the instrument dashboard through the magnetic male connector or the magnetic male spring crochet connector to complete the signal input; the orange box Out is connected to the oscilloscope module in the instrument dashboard through the magnetic male connector or the magnetic male spring crochet connector to measure the parameters of the output signal. Adjustment Figure 23 The size of the potentiometer shown in the red dotted box can adjust the static operating point of the circuit. The measurement of internal circuit parameters such as the static operating point of the transistor and various parameters required by the experimental instructions can be completed by the voltmeter, DC ammeter or oscilloscope in the instrument experiment board.

[0071] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
