[0001] The present invention relates to the technical field of new energy electric vehicle electrical teaching, and more particularly to a simulation training device for the electrical system of a new energy electric vehicle. Background Art

[0002] In the context of the rapid development of the new energy electric vehicle industry, as the core control unit, the complexity and technical integration of the electrical system are constantly increasing, posing higher requirements for the professional training of practitioners. Universities and vocational training institutions urgently need high-fidelity simulation training devices to train students to master key skills such as battery management, motor control, and energy distribution.

[0003] In the field of simulation training for the electrical system of new energy electric vehicles, traditional training devices usually have the following technical problems. Traditional training platforms can only provide a single fixed work station and cannot simultaneously meet the parallel training needs of two independent electrical modules (such as a battery management system module and a motor drive system module), resulting in a single teaching scenario. Moreover, the switching between single / double teaching scenarios relies on manual disassembly and assembly of equipment or moving heavy platforms, and frequent operation is likely to cause wear of electrical interfaces, increasing maintenance costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a simulation training device for the electrical system of a new energy electric vehicle to solve the problem that the traditional training device in the prior art is limited by a single fixed work station and cannot support parallel training of dual modules, resulting in a single teaching scenario.

Detailed implementation manners

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0035] Please refer to Figures 1 to 9 , a new energy electric vehicle electrical system simulation training device, including a training bench 100 and two independently arranged training modules 200 for simulating the electrical system of a new energy electric vehicle. The training module 200 is prior art and will not be elaborated here. A first working area, a second working area and a storage area located between them are arranged on the training bench 100 along its length direction. It further includes:

[0036] A first table board 300 for carrying one of the training modules 200, and a first guide member 310 for restricting its movement along the length direction of the training bench 100 is connected to one side thereof;

[0037] The second board 400 that carries another training module 200 is provided with a lateral support portion 410 at its bottom. One side of the lateral support portion 410 is connected to a second guiding member 420 that restricts its movement along the length direction of the training table 100. One side of the second board 400 is connected to a third guiding member 430 that restricts its movement along the height direction of the training table 100 relative to the lateral support portion 410.

[0038] The adjusting mechanism 500 can be switched between an unfolded mode, a semi-unfolded mode, and a storage mode. When the adjusting mechanism 500 is in the unfolded mode, it can drive the first board 300 and the second board 400 to move to the working positions in the first working area and the second working area respectively.

[0039] When the adjusting mechanism 500 is in the semi-unfolded mode, it can drive the second board 400 to move to the storage area position, and can drive the first board 300 to move to the working position in the first working area or the second working area.

[0040] When the adjusting mechanism 500 is in the storage mode, it can drive the first board 300 and the second board 400 to move to the storage area to form an overlapping storage state.

[0041] Specifically, the optimal layout of the teaching space is realized through three longitudinally distributed areas (the first working area, the second working area, and the storage area) on the training table 100. The first board 300 is guided by the first guiding member 310 to achieve linear longitudinal movement. The second board 400 realizes two-dimensional displacement through compound guiding (the lateral support portion 410, the second guiding member 420, and the third guiding member 430). Driven by the adjusting mechanism 500, the first board 300 and the second board 400 are controlled to switch among the three areas, forming three teaching modes, solving the problem of low space utilization rate of traditional training devices, realizing the rapid switching between single / double teaching scenarios, and avoiding the problem of interface wear caused by frequent disassembly and assembly of equipment.

[0042] Please refer to Figure 1 、 Figure 2 and Figures 6 to 9, in an embodiment of the present invention, the adjusting mechanism 500 includes a synchronous belt 510, two transmission wheels 520, a rotary driving member, a first connecting member 530, a second connecting member 540, a limiting member 550, and a height adjusting assembly 560. The two transmission wheels 520 are distributed along the length direction of the training bench 100 and are respectively rotatably installed on the side walls of the training bench 100. One of the transmission wheels 520 is connected to a rotary driving member for driving it to rotate around its own axis on one side. The rotary driving member can be a rotary cylinder or a motor, and the rotary driving member is fixedly installed on the side wall of the training bench 100. The synchronous belt 510 bypasses the two transmission wheels 520. One side of the first connecting member 530 is fixedly connected to the synchronous belt 510, and the other side of the first connecting member 530 is fixedly connected to the first table board 300. One side of the second connecting member 540 is fixedly connected to the synchronous belt 510. When the limiting member 550 is in a limiting state, the second connecting member 540 cannot move relative to the lateral support portion 410. When the limiting member 550 is in a non-limiting state, the second connecting member 540 can move relative to the lateral support portion 410. The height adjusting assembly 560 is used to drive the second table board 400 to move along the height direction of the training bench 100;

[0043] Among them, both the first connecting member 530 and the second connecting member 540 can be connected to the synchronous belt 510 by two clamping plates. A clamping channel for clamping the synchronous belt 510 is provided between the two clamping plates, and the two clamping plates can be connected by means of bolt connection;

[0044] Specifically, by driving one of the transmission wheels 520 to rotate through the rotary driving member, the synchronous belt 510 is driven to circulate by the transmission wheel 520. Driven by the synchronous belt 510, the first connecting member 530 directly drives the first table board 300 to move along the length direction of the training bench 100. The second connecting member 540 realizes the linkage / disconnection with the lateral support portion 410 through the state switching of the limiting member 550, that is, realizes the linkage / disconnection with the first table board 400. At the same time, the height adjusting assembly 560 drives the second table board 400 to move along the height direction of the training bench 100, so as to realize the coordinated control of the first table board 300 and the second table board 400;

[0045] When the adjusting mechanism 500 is in the unfolded mode, the limiting member 550 is in a limiting state. Driven by the synchronous belt 510, the first connecting member 530, and the second connecting member 540, the switching of the working positions of the first table board 300 and the second table board 400 in the first working area and the second working area can be realized;

[0046] When the adjustment mechanism 500 is in the semi-expanded mode, the limiting member 550 is first in the limiting state, and the second platen 400 is moved to the storage area. Then the state of the limiting member 550 is switched to the non-limiting state. At this time, the connection between the lateral support portion 410 and the second connecting member 540 is disconnected. Thus, one of the transmission wheels 520 can be driven by the rotary driving member to rotate reciprocally, so as to realize the position switching of the first platen 300 between the first working area and the second working area;

[0047] When the adjustment mechanism 500 is in the storage mode, similar to the semi-expanded mode, the limiting member 550 is first in the limiting state, and the second platen 400 is moved to the storage area. Then the state of the limiting member 550 is switched to the non-limiting state. At this time, the connection between the lateral support portion 410 and the second connecting member 540 is disconnected. Thus, one of the transmission wheels 520 can be driven by the rotary driving member to rotate, so that the first platen 300 is moved into the storage area, thereby realizing that the first platen 300, the second platen 400, and the two training modules 200 are all stored in the storage area.

[0048] Please refer to Figure 1 and Figure 5 In an embodiment of the present invention, the limiting member 550 includes a plug pin 551, a telescopic driving member 552, a fixing plate 553, and a plurality of jacks 554 formed on the fixing plate 553. The outer side wall of the plug pin 551 is slidably connected to the lateral support portion 410. One side of the fixing plate 553 is fixedly connected to the second connecting member 540. The plug pin 551 can be partially inserted into one of the jacks 554. The bottom end of the plug pin 551 is fixedly connected to the moving end of the telescopic driving member 552. The fixed end of the telescopic driving member 552 is fixedly connected to the lateral support portion 410. The telescopic driving member 552 can be a telescopic air cylinder or a hydraulic cylinder;

[0049] A third guide rail 570 is slidably connected to one side of the second connecting member 540. The third guide rail 570 is fixedly installed on the inner wall of the training table 100. The length direction of the third guide rail 570 is the same as the length direction of the training table 100 to improve the moving stability of the second connecting member 540;

[0050] Specifically, the movement of the plug pin 551 is driven by the expansion and contraction of the moving end of the telescopic driving member 552. When the plug pin 551 is partially inserted into one of the jacks 554, the limiting member 550 is in the limiting state. Under the action of the plug pin 551, the second connecting member 540 cannot move relative to the lateral support portion 410;

[0051] When the plug pin 551 disengages from the jack 554, the limiting member 550 is in the non-limiting state, and the second connecting member 540 can move relative to the lateral support portion 410.

[0052] Please refer to Figure 1 and Figure 4, in an embodiment of the present invention, the height adjustment assembly 560 includes a positioning plate 561, a guide wheel 562, a connecting vertical plate 563, and a guide groove 564 formed on the positioning plate 561. The positioning plate 561 is fixedly installed on the training table 100. The outer wall of the guide wheel 562 is in rolling connection with the inner wall of the guide groove 564. The guide groove 564 is composed of a horizontal groove and two symmetrically arranged inclined grooves. The two ends of the horizontal groove are respectively communicated with the bottom ends of the two inclined grooves. The guide wheel 562 is rotatably installed on the connecting vertical plate 563, and the top end of the connecting vertical plate 563 is fixedly connected to the second table plate 400;

[0053] Specifically, when the limiting member 550 is in the limiting state, the synchronous belt 510 drives the second connecting member 540 to move. The second connecting member 540 drives the transverse support portion 410 to move through the limiting member 550. The transverse support portion 410 drives the second table plate 400 to move synchronously through the third guiding member 430. The second table plate 400 drives the guide wheel 562 to move through the connecting vertical plate 563. The guide wheel 562 moves along the guide groove 564. Under the trajectory limitation of the guide groove 564, the displacement of the connecting vertical plate 563 in the length direction of the training table 100 is converted into a lifting motion, that is, the lifting motion of the second table plate 400 is realized, so that the coordinated control of the first table plate 300 and the second table plate 400 can be realized by a single power source; and when the second table plate 400 is in the storage area, the guide wheel 562 is in the horizontal groove section of the guide groove 564. After the connection between the transverse support portion 410 and the second connecting member 540 is disconnected, under the self-weight of the second table plate 400 and the training module 200, the second table plate 400 will not move upward under external disturbances such as vibration and cause interference.

[0054] In an embodiment of the present invention, a displacement sensor is further included, and the displacement sensor is used to measure the moving distance of the second connecting member 540;

[0055] Specifically, a magnetic grating or grating displacement sensor can be used to monitor the position of the second connecting member in real time, so that the limiting member 550 can accurately connect the second connecting member 540 and the transverse support portion 410.

[0056] Please refer to Figure 2 , in an embodiment of the present invention, the first guiding member 310 is two first guide rails fixedly installed on the training table 100, and the lower side of the first table plate 300 is respectively in sliding connection with the first guide rails.

[0057] Please refer to Figure 1, in an embodiment of the present invention, the second guiding member 420 includes two supporting seats 421 and two second guide rails 422. The bottom ends of the two supporting seats 421 are respectively fixedly connected to the training bench 100. The length directions of the two second guide rails 422 are the same as the length direction of the training bench 100. The two second guide rails 422 are respectively fixedly installed on the two supporting seats 421. The lower side of the transverse supporting portion 410 is respectively slidably connected to the two second guide rails 422.

[0058] Please refer to Figure 3 , in an embodiment of the present invention, the third guiding member 430 is a plurality of guide rods. The height direction of the guide rods is the same as the height direction of the training bench 100. The plurality of guide rods are evenly arranged at the bottom of the second table board 400, and the top ends of the plurality of guide rods are respectively fixedly connected to the second table board 400. The outer side walls of the plurality of guide rods are respectively slidably connected to the transverse supporting portion 410.

[0059] In an embodiment of the present invention, an infrared ranging sensor is further included and arranged at the front end of the moving paths of the first table board 300 and the second table board 400, for detecting the distance to the front obstacle in real time during the movement of the first table board 300 and the second table board 400;

[0060] Specifically, by using the infrared ranging sensor to scan the moving path in real time, it can be specifically set to trigger emergency braking when the detected distance to the obstacle is <150 mm to avoid mechanical collision.

[0061] In an embodiment of the present invention, a corresponding control unit can be set for cooperation.

Compared with the general-purpose microprocessor applied in a personal computer, it emphasizes more on self-supply (without external hardware) and cost saving.
