[0038] The front end surface of the first display board 2 is used to install indicator lights, banana plugs 18, draw circuit diagrams, etc., that is, try not to add weight to the top of the device to maintain its stability.

[0039] The second display panel 19 is used to install the ignition switch 5, the starter relay 8, the fuse box 17 (the first to third fuses are all installed in the fuse box 17), the engine control module 6, the automatic transmission gear switch 7, etc.

[0040] The starter 4 and the power supply battery 3 are installed at the bottom of the inner cavity of the stand body 1, and the top of the third display board 20 is rotatably connected to the stand body 1, so that it can be used to operate the starter 4 and the power supply battery 3.

[0041] The front end surface of the third display board 20 can be used to draw corresponding propaganda slogans, teaching contents, close the inner cavity of the stand body 1, etc.

[0042] In order to provide a detailed introduction to the automobile starting process, principles, etc., the equipment provided in this embodiment also includes a power supply battery 3, a starter 4, an ignition switch 5, an engine control module 6, an automatic transmission gear switch 7, a starter relay 8, multiple indicator lights, multiple fuses, etc.

[0043] In combination with the accompanying drawings, the first indicator light 9, the first fuse 10 (whose maximum load is 40A), the second indicator light 11, the input end of the ignition switch 5, and the ON end of the ignition switch 5 are sequentially connected in series and then connected in series with the power supply battery 3, and the first indicator light 9 is adjacent to the positive electrode of the power supply battery 3;

[0044] Secondly, the ST end of the ignition switch 5, the start signal input end of the engine control module 6, the negative electrode access end of the engine control module 6, and the negative electrode of the power supply battery 3 are connected in series in sequence; and the ST end of the ignition switch 5, the two control ends of the starter relay 8, and the start control end of the engine control module 6 are connected in series in sequence.

[0046] The positive electrode of the power supply battery 3, the fourth indicator light 14, and the end B of the starter 4 are connected in series in sequence.

[0047] That is, when the power supply battery 3 supplies power:

[0048] When the ignition switch 5 is in the OFF position (the input end of the ignition switch 5 is connected to its OFF end), all indicator lights are off, and the surface equipment is in the disconnected state;

[0049] When the ignition switch 5 is in the ON position (the input end of the ignition switch 5 is connected to its ON end), the first indicator light 9 lights up, indicating that the main circuit is powered (corresponding to the power supply battery 3), and the second indicator light 11 and the third indicator light 12 are both on, indicating that the starter 4 is in the waiting state. At this time, the ST end of the ignition switch 5 is open, the S end of the starter 4 has no power, and it will not start.

[0050] When the ignition switch is in the ST gear (the input end of the ignition switch 5 is connected to its ST end), the second indicator light 11 and the third indicator light 12 are both off, the first indicator light 9 is still on, the start signal input end of the engine control module 6 is energized, and the two control ends of the starter relay 8 are energized so that its two action ends are closed, so that the automatic transmission gear switch 7 is closed, then the S end of the starter 4 is energized, combined with the B end of the starter 4 connected to the positive pole of the power supply battery 3, the starter 4 is actuated to achieve the starting purpose.

[0051] That is, through the setting of the above-mentioned circuit and multiple indicator lights, the circuit changes before and after the starter 4 is started can be effectively demonstrated, and the simulation of the actual control process of the starter 4 can be realized, which is conducive to students understanding the control process of the starter 4 through the test bench.

[0053] For the convenience of display, a connection relationship diagram of the power supply battery 3, starter 4, ignition switch 5, starter relay 8, engine control module 6, automatic transmission gear switch 7, first to fourth indicator lights 14, and first to second fuses is drawn on the first display board to demonstrate the control principle of the starter 4, and the first to fourth indicator lights 14 are respectively installed at corresponding positions in the connection relationship diagram, so as to facilitate intuitive understanding of the corresponding control logic.

[0054] In order to observe whether the ignition switch 5 is powered and to show the power supply status of the ignition switch 5, a fifth indicator light 15 is connected in series between the first fuse and the first indicator light 9 to indicate whether the ignition switch 5 is powered.

[0056] In order to observe whether there is a path between the action end of the start relay 8 and the input end of the automatic transmission gear switch 7, a seventh indicator light is connected in series between the action end of the start relay 8 and the automatic transmission gear switch 7;

[0057] Similarly, in order to observe whether there is a passage between the automatic transmission gear switch 7 and the S short of the starter, an eighth indicator light is connected in series between the automatic transmission gear switch 7 and the S end of the starter 4;

[0059] In this embodiment, the sixth to ninth indicator lights are not shown with reference numerals, and their installation positions are shown in the figure.

[0060] In order to reduce the current of the control circuit part to improve its safety and to demonstrate the purpose of low current controlling high current, in this embodiment, a third fuse 16 (with a maximum load of 10A) is connected in series between the ST end of the ignition switch 5 and the start signal input end of the engine control module 6, and between the ST end of the ignition switch 5 and the control end of the start relay 8, so as to reduce the current in the corresponding circuit to achieve the aforementioned purpose.

[0061] In order to facilitate the arrangement of the equipment, in this embodiment, the first fuse 10 , the second fuse 13 and the third fuse 16 are all installed in the fuse box 17 .

[0062] In order to facilitate fault, current or voltage detection, in this embodiment, banana plugs 18 are connected in series at the four ends of the starter relay 8, the S end of the starter 4, and the two ends of the power supply battery 3.

[0063] That is, with the help of the banana plug 18, the detection of relevant contents can be effectively performed.

[0064] In order to realize fault simulation and facilitate the teaching of related content, in the present embodiment, a seesaw switch 21 is also connected in series between the first indicator light 9 and the power supply battery 3, between the ST end of the ignition switch 5 and the start signal input end of the engine control module 6, between the ST end of the ignition switch 5 and the control end of the starter relay 8, between the control end of the starter relay 8 and the start control end of the engine control module 6, between the action end of the starter relay 8 and the automatic transmission gear switch 7, and between the automatic transmission gear switch 7 and the S end of the starter 4.
