In addition, when the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements

[0038] In the related art, the display of vehicles is also limited to the appearance of the vehicle, and the internal structure of the vehicle cannot be intuitively displayed. For example, the structural layout of an electric vehicle and the overall vehicle energy management cannot be intuitively and dynamically displayed

[0039] In view of the above problems, according to Figures 1 to 9As shown in the figure, an embodiment of the present disclosure provides a display stand for displaying the structural layout and vehicle energy management of an electric vehicle. The display stand may include a display stand body 1, a vehicle model device 2, a charging device, and a thermal management device.

The thermal management device may include a heat exchanger 41, a cooler 420, a PTC heater 421, a drive heat exchange light strip 43, and a battery heat exchange light strip 44. One end of the drive heat exchange light strip 43 is connected to the output end of the heat exchanger 41, and the other end passes through the drive assembly 21 and is connected to the input end of the heat exchanger 41. One end of the battery heat exchange light strip 44 is connected to the output end of the cooler 420, and the other end sequentially passes through the power battery 22 and the PTC heater 421 and is connected to the input end of the cooler 420 to simulate the flow direction of the thermal management medium in the starting state of the electric vehicle through the thermal management device.

[0040] Through the above technical solution, a vehicle model device 2 is provided on the display stand body 1, and the charging device and the thermal management device connected to the vehicle model device 2 are used to simulate and display the flow directions of electric energy and thermal management medium in the starting state of the electric vehicle, so as to visually and dynamically present the energy management of the whole vehicle, and at the same time enable the viewers to truly and comprehensively understand the structural layout of the electric vehicle.

[0041] Among them, both the vehicle model device 2 and the thermal management device may adopt wooden models to reduce the economic cost. Of course, in order to facilitate the viewers to distinguish each device and to enhance the viewing and experience feelings of the viewers, the colors adopted by the vehicle model device 2 and the thermal management device may be different. For example, the drive assembly 21 of the vehicle model device 2 may be spray-painted silver, the power battery 22 may be spray-painted blue, and the heat exchanger 41 of the thermal management device may be spray-painted black. The present disclosure is not limited thereto.

[0042] In order to further improve the ornamental value, the wooden model for presenting the structure of the power battery 22 may include a display part and a support part. The support part may be configured as a support plate 220, and the support plate 220 may be spray-painted blue. The display part is located at the top of the support plate 220, and the display part may adopt a colorless and transparent acrylic material so that the viewers can directly appreciate the flow of electric energy and thermal management medium inside the power battery 22 in the starting state of the electric vehicle.

[0043] Optionally, the display stand may further include a rear drive module docking station to facilitate the display of the rear part of the electric drive system, improve the operability of the display stand, enable relevant personnel to adjust the structural layout of the vehicle model device 2 of the display stand according to the structural layout of different electric vehicles, and enhance the adaptability of the display stand.

[0044] In some implementable ways, for example, referring to Figure 1 as shown, the first side A of the display stand body 1 may be higher than the second side B of the display stand body 1, so that the display stand body 1 is inclined. When the viewer stands on the second side B of the display stand body 1, the viewer can overlook the display stand to obtain the best viewing experience.

[0045] In some implementable ways, for example, referring to Figures 1 to 4 as shown, the charging light strip 31 may include a fast charging light strip 310 and a slow charging light strip 311. One ends of the fast charging light strip 310 and the slow charging light strip 311 are both connected to the charging interface 23, and the other ends both pass through the drive assembly 21 and are communicated with the connection light strip 32. To simulate the power flow direction under the charging state of the electric vehicle through the above structure, so as to facilitate the viewer to intuitively understand the charging principle and specific structural layout of the electric vehicle.

[0046] Among them, in order to facilitate the viewer to distinguish the fast charging light strip 310 and the slow charging light strip 311, the diameter of the fast charging light strip 310 may be greater than that of the slow charging light strip 311 or the colors that the fast charging light strip 310 can display are different from the colors that the slow charging light strip 311 can display. The present disclosure is not limited to this, and those skilled in the art can make adaptive adjustments according to the actual situation.

[0047] In some implementable ways, for example, referring to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 as shown, the drive assembly 21 may include a three-in-one electric drive system 210 and a distribution box 211. The charging device may further include a recovery light strip 33. One end of the recovery light strip 33 is connected to the three-in-one electric drive system 210, and the other end is connected to the distribution box 211. Through the above structure, the power flow directions in the two modes of the electric drive mode and the energy recovery mode when the electric vehicle starts are simulated and displayed, so that the viewer can intuitively understand the working principles and specific structural layouts of the above two modes of the electric vehicle.

[0048] In some implementable ways, for example, referring to Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown, the thermal management device may further include a second liquid storage tank 47 and a second pump body 48 disposed on the battery heat exchange light strip 44, the PTC heater 421 is located on a side close to the input end of the cooler 420, and the second liquid storage tank 47 and the second pump body 48 are both located on a side close to the output end of the cooler 420. The above structure is used to simulate and display the heating and cooling modes of the power battery of the electric vehicle, so that the audience can intuitively understand the working principle and specific structural arrangement of the electric vehicle in the above two modes.

[0049] In order to further simulate and demonstrate the heating mode and cooling mode of the power battery, in some practicable ways, for example, referring to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the battery heat exchange light strip 44 may include a third section 440 located on the power battery 22, a fourth section 441 connected to the second liquid storage tank 47 and the second pump body 48 in sequence from the output end of the cooler 420 and connected to the third section 440, a fifth section 442 located between the PTC heater 421 and the power battery 22, and a sixth section 443 located between the cooler 420 and the PTC heater 421. The third section 440, the fourth section 441 and the fifth section 442 can display at least two different colors, and the sixth section 443 can display at least one color that is the same as the third section 440, the fourth section 441 and the fifth section 442. For example, the third section 440, the fourth section 441 and the fifth section 442 can all display red and blue, and the sixth section 443 can display red, so as to simulate and display the heating and cooling modes of the power battery through the color changes between each section, so as to provide a dynamic viewing experience for viewers.

[0050] The third section 440 may be configured as a bending structure having a plurality of bending portions surrounding the surface of the power battery 22, for example, may be configured as a "彐"-shaped structure opening toward the right side. The present disclosure is not limited thereto.

[0051] In order to further simulate and demonstrate the flow direction of the thermal management medium when the drive system is cooled, in some practicable ways, for example, referring to Figure 1 , Figure 2 and Figure 9 As shown, the thermal management device may further include a first liquid storage tank 45 and a first pump body 46 disposed on the driving heat exchange light strip 43, wherein the first liquid storage tank 45 is located on a side close to the output end of the driving heat exchange light strip 43, and the first pump body 46 is located between the first liquid storage tank 45 and the driving assembly 21. By providing the first liquid storage tank 45 and the first pump body 46, the specific structure for realizing the cooling of the driving system inside the electric vehicle is fully restored, so that the viewers can intuitively and comprehensively understand the principle and structural arrangement of the cooling of the driving system.

[0052] In some implementable ways, for example, referring to Figure 1 As shown, the charging light strip 31, the connecting light strip 32, the driving heat exchange light strip 43, the battery heat exchange light strip 44, and the recycling light strip 33 can all include a PVC transparent round tube and an LED flowing light strip disposed within the PVC transparent round tube. By using the PVC transparent round tube and the LED flowing light strip, the flow of electric energy and heat management medium of an electric vehicle is simulated by the LED flowing light strip, and the PVC transparent round tube enables viewers to see the flashing condition of the LED flowing light strip, which is more intuitive and convenient.

[0053] It should be noted that the LED flowing light strip adopted in the present disclosure can be one that can adjust and control the color and flowing direction. For example, the LED flowing light strip can display two colors, red and blue, respectively. Regarding the specific structure and function of the LED flowing light strip, those skilled in the art can search and refer to existing literature, and the present disclosure will not elaborate herein.

[0054] Certainly, the LED flowing light strip can also be one that can only display one color and cannot control the flowing direction. For example, for the charging light strip 31, the connecting light strip 32, the driving heat exchange light strip 43, the battery heat exchange light strip 44, and the recycling light strip 33, the colors of the LED flowing light strips of each light strip can be different, or the colors of the LED flowing light strips of some light strips can be the same while those of other light strips are different, and the number of LED flowing light strips of each light strip can also be different to display different colors or flowing directions. For example, the colors of the LED flowing light strips of the charging light strip 31, the connecting light strip 32, and the recycling light strip 33 can all be green, the number of LED flowing light strips of the connecting light strip 32 and the recycling light strip 33 can both be two, and the flowing directions of the two LED flowing light strips are different. The number of LED flowing light strips of the driving heat exchange light strip 43 can be two, and the two LED flowing light strips respectively correspond to the first section of the road 430 and the second section of the road 431 to display different colors. The number of LED flowing light strips of the battery heat exchange light strip 44 can be three, and two LED flowing light strips can be disposed inside the interconnected third section of the road 440, the fourth section of the road 441, and the fifth section of the road 442 to display different colors. One LED flowing light strip can be disposed inside the sixth section of the road 443 to display at least one color that is the same as the LED flowing light strips inside the third section of the road 440, the fourth section of the road 441, and the fifth section of the road 442. The present disclosure is not limited thereto, as long as the function of displaying the overall vehicle energy of the electric vehicle can be achieved, and those skilled in the art can make adaptive adjustments according to actual needs.

[0055] In some implementable ways, for example, referring to Figure 1As shown, the display stand may also include a control device 5, which is electrically connected to the charging device and the thermal management device, respectively, so that the viewers can control the charging device and the thermal management device through the control device, and the control device may include at least one of a slow charging switch, a fast charging switch, an electric drive switch, an energy recovery switch, a battery cooling switch, a battery heating switch, and a motor cooling switch. So that the viewers can control the display stand to display the energy flow of the electric vehicle according to their own wishes, enhance the sense of participation of the viewers, improve the operability of the display stand, and bring the viewers a better visiting experience.

[0056] The limitation of the types and number of switches of the control device in the present disclosure is only for the present disclosure.
