[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1-2 As shown, this application provides an integrated testing and diagnostic teaching device for automotive power chassis, including a platform 1, on which two wheel carriers 2 are installed. The wheel carriers 2 can simulate the process of a car driving, and the platform 1 can also be used to install basic devices in the automotive chassis power system.

[0026] like Figure 1-2 As shown, a teaching mechanism is installed on the surface of the platform 1. This teaching mechanism includes a motor 31 fixedly connected to the platform 1. The output end of the motor 31 is installed on the wheel frame 2, and the motor 31 drives the wheel frame 2 to rotate. The motor 31 is electrically connected to a power controller 32 and a battery 33. The battery 33 is electrically connected to a charger module 34. The power controller 32 is electrically connected to a high-pressure heater 35 and a high-pressure air conditioning compressor 36. The battery 33, power controller 32, high-pressure heater 35, and high-pressure air conditioning compressor 36 are all fixedly installed on the platform 1. The power controller 32 is electrically connected to a control unit measurement terminal 37. A circuit simulation fault setting system is connected between the control unit measurement terminal 37 and the power controller 32. The power chassis components corresponding to the original vehicle are completely installed on the platform, and the power chassis faults are set through the circuit simulation fault setting system, which facilitates the troubleshooting and clearing of faults on the platform. This is beneficial for teachers to explain the principles of the power chassis and helps students quickly grasp the logical principles of the power chassis of new energy vehicles.

[0027] It is further noted that the control unit measurement terminal 37 is connected in parallel to the wiring harness of the power control device. The wiring harness connectors between the motor 31, the power control device and the battery 33, the battery 33 and the charger module 34, and between the power control device, the high-voltage heater 35 and the high-voltage air conditioning compressor 36 are all parallel double connectors. This structure allows the training system to operate without being limited by the external environment, enabling fault setting through a simulated fault system and reducing equipment wear. Furthermore, using new energy vehicles as a research and development platform, and employing a modular, dual-power supply design, enhances product stability and realism, enabling the simulation of real-world vehicle fault environments and product demonstration updates.

[0028] like Figure 3As shown, a placement mechanism 4 is installed on one side of the tabletop 1. This placement mechanism 4 includes two insertion holes 412 formed on the tabletop 1 and an auxiliary mechanism 53 also formed on the tabletop 1. Insertion posts 405 are slidably connected to the inner walls of the insertion holes 412. A placement box 406 is fixedly connected to one end of each insertion post 405. The cooperation between the insertion post 405 and the insertion holes 412 fixes the placement box 406 to one side of the tabletop 1. Two rectangular grooves 407 are formed opposite each other on the inner wall of the placement box 406. A rectangular block 408 is slidably connected to the inner wall of 407. A layered box 409 is fixedly connected to one side of the rectangular block 408. The layered box 409 is placed inside the placement box 406, and the size of the insertion post 405 matches the size of the insertion hole 412. When personnel need to install the placement box 406, they only need to align the position of the insertion post 405 on the placement box 406 with the position of the insertion hole 412, and then insert the insertion post 405 into the insertion hole 412, thereby initially installing the placement box 406 on the table body 1.

[0029] To ensure a more stable connection between the placement box 406 and the platform 1, such as Figure 3 As shown, two fixing blocks 401 are fixedly connected to one side of the table body 1. Bolt rods 402 are threadedly connected to the inner wall of the fixing blocks 401. One end of the bolt rods 402 is rotatably connected to a limiting block 403. Two limiting rods 404 are symmetrically fixedly connected to the surface of the limiting blocks 403. The limiting rods 404 slide through the surface of the fixing blocks 401. When the insertion post 405 is inserted into the insertion hole 412, the personnel can rotate the bolt rods 402. During the rotation of the bolt rods 402, the two limiting blocks 403 will be driven to move closer to each other. When the two limiting blocks 403 are close to the two sides of the placement box 406, the placement box 406 is fully installed. At the same time, the setting of the limiting rods 404 can prevent the angle of the limiting blocks 403 from rotating during the movement, thereby affecting the limiting performance of the limiting blocks 403.

[0030] Meanwhile, a lifting block 410 is fixedly connected to the surface of the layer box 409, and an anti-slip pad 411 is glued to the surface of the lifting block 410. The lifting block 410 and the anti-slip pad 411 can help personnel take the layer box 409 out of the placement box 406, thereby facilitating the sorting and cleaning of the parts inside the layer box 409.

[0031] like Figure 1As shown, an auxiliary mechanism 53 is installed on the tabletop 1. The auxiliary mechanism 53 includes four electric telescopic rods 51 and four connecting parts 52. The input end of the electric telescopic rods 51 is fixedly connected to the bottom of the tabletop 1. The four connecting parts 52 are in pairs, and each pair of connecting parts 52 is rotatably connected to the wheel frame 2. The connecting parts 52 are fixedly connected to the tabletop 1 by bolts. The electric telescopic rods 51 can adjust the height of the tabletop 1 to avoid the situation where people have to bend over to study when the tabletop 1 is low, thus avoiding the situation of lower back fatigue. At the same time, in order to prevent the wheel frame 2 from rubbing against the tabletop 1 during rotation, the connecting parts 52 can support the wheel frame 2, thereby also having the effect of limiting the movement of the wheel frame 2.

[0032] Working principle: By setting up auxiliary mechanism 53, personnel can learn about the power chassis of new energy vehicles without being affected by the external environment. This also reduces energy consumption by simulating the power chassis. Power chassis components corresponding to the original vehicle are installed on the platform, and power chassis faults are set using a circuit simulation fault setting system. This facilitates troubleshooting and clearing faults, helps teachers explain the principles of the power chassis, and helps students quickly grasp the logical principles of the power chassis of new energy vehicles.

[0033] When the placement mechanism 4 is needed, personnel can perform preliminary installation of the placement box 406 by using the insertion rod and the insertion hole 412. Finally, the bolt rod 402 drives the two limit blocks 403 to clamp the placement box 406, thereby achieving the final installation of the placement box 406. This improves the stability of the connection between the placement box 406 and the table body 1. At the same time, the layered box 409 inside the placement box 406 can organize and categorize the parts, making it convenient for personnel to access them.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
