Description

Technical Field

[0001] The utility model relates to the technical field of practical training teaching equipment, in particular to a new energy vehicle chassis teaching practical training demonstration board. Background Art

[0002] With the continuous development of new energy vehicle technology, talents in new energy vehicle technology have also emerged. In order to conduct a more in-depth study of new energy vehicles, theory and practice are usually combined to improve the learning effect of students. Compared with internal combustion vehicles, new energy vehicles are characterized by flexible structure. The main energy sources of internal combustion vehicles are gasoline and diesel, while new energy vehicles use electric energy and are driven by electric sources and electric motors. This is also the main difference between new energy vehicles and transmission fuel vehicles. Among them, the main source of electricity in new energy vehicles comes from the battery pack. The battery pack looks like a large module on the surface and is installed on the chassis of the car. However, the interior of the battery pack has very complex components, including not only multiple groups of battery modules connected in series, but also some auxiliary equipment, such as liquid cooling plates for dissipating heat inside the battery pack, copper bars that connect each battery module to form a high-voltage circuit, etc.

[0003] In order to make it easier for students to learn and understand the chassis of new energy vehicles, a simulation environment is usually provided in combination with practical training teaching devices to help students better understand and master relevant knowledge. However, current teaching devices generally place the model of the vehicle chassis directly on the teaching table for students to observe and study, but the internal structure of the battery pack installed on the chassis of new energy vehicles cannot be observed and cannot be deeply understood, resulting in reduced learning effect. Utility Model Content

[0004] The embodiment of the utility model provides a new energy vehicle chassis teaching and training demonstration board to solve the above-mentioned technical problems.

[0005] The embodiment of the utility model adopts the following technical scheme: it includes a battery pack box body simulating a new energy vehicle battery pack and an expansion component, wherein the battery pack box body is located in the middle of the chassis simulation frame, the battery pack box body is composed of a plurality of stacked sub-packaging boxes, and a battery simulation unit simulating the internal structure of the battery pack is installed inside the plurality of sub-packaging boxes, the expansion component is located on both sides of the battery pack box body, and is used to unfold the battery pack box body, the expansion component includes a gear and a transmission rack, the transmission rack is connected to the outer wall of the sub-packaging box, and the outer edge of the gear is meshed with the transmission rack, and the battery pack box body can be unfolded through the expansion component, so that students can check the internal structure of the battery pack box body.

[0006] Furthermore, a connecting seat is provided on the outer wall of the packaging box located in the middle, and a first driving member is connected to the connecting seat. The output end of the first driving member is connected to the gear, and the transmission rack is connected to the packaging boxes at the upper and lower ends. The gear can be driven to rotate by the first driving member, thereby driving the transmission rack to move.

[0007] Furthermore, the upper and lower ends of the side walls of the packaging box located in the middle are integrally formed with sliding tracks, and the two adjacent packaging boxes are slidably connected by the sliding tracks, providing guidance and limiting for the packaging box when unfolded, so that the packaging box moves in a straight line when unfolded.

[0008] Furthermore, a receiving column is fixedly connected to the outer wall of the connecting seat, and the other end of the receiving column is rotatably connected to a receiving platform. A telescopic member is provided at the bottom of the receiving platform, and the battery pack box body can be separated from the chassis simulation frame through the telescopic member.

[0009] Furthermore, a second driving member is provided on an outer wall of one side of the receiving platform, and an output end of the second driving member is connected to one end of the receiving column. Under the action of the second driving member, the battery pack box can be flipped to make the unfolded packaging box more intuitively face the students, which is convenient for students to view from a distance.

[0010] Furthermore, a display seat is connected to the lower part of the chassis simulation frame, and the fixed end of the telescopic member is fixedly connected to the upper end surface of the display seat, so that the chassis simulation frame can be easily placed through the display seat.

[0011] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0012] In the utility model, the receiving platform is driven to move upward by the telescopic member, so that the battery pack box body can be lifted from the middle of the chassis simulation frame, so that the battery pack box body and the chassis simulation frame are separated, so that the trainees can more intuitively see the state of the chassis simulation frame when the battery pack box body is not installed, and the gear is driven to rotate by the first driving member, and the sub-packaging boxes at the upper and lower ends are driven to move oppositely through the transmission rack, so that the battery pack box body can be dispersed and expanded. The structure allows the trainees to more clearly observe the various simulation devices installed in each sub-packaging box, so as to fully understand the internal structure of the new energy battery pack; when the second driving member drives the connecting seat to rotate, the expanded battery pack box body can be flipped over, so that the battery pack box body is tilted or vertical, so that some trainees who are far away from the display seat can also observe the internal structure of the battery pack box body, thereby improving the teaching quality and the learning effect of the trainees.
