DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Embodiment 1

[0028] like Figure 1-Figure 5 As shown, a vehicle idling state display stand includes a platform frame 1, a driving assembly 2 and a driven assembly 3. The platform frame 1 serves as a main support. The driving assembly 2 includes two driving rollers 5 rotatably connected to the platform frame 1, which are used to place the driving wheels of the vehicle 4. The driving wheels are trapped between the two driving rollers 5. When the driving wheels rotate, the friction force is used to drive the two driving rollers 5 to rotate. The driving assembly 2 can be arranged in one group, that is, the driving rollers 5 are longer, and the two driving wheels of the vehicle 4 are placed on the same group of driving assemblies 2. The driving assembly 2 can also be arranged in two groups, that is, the two driving wheels of the vehicle 4 are respectively placed on one group of driving assemblies 2.

[0029] The driven assembly 3 has the same structure as the driving assembly 2, and includes two driven rollers 6 rotatably connected to the platform frame 1 for placing driven wheels of the vehicle 4. The driven assembly 3 can also be provided in one group or two groups.

[0030] One of the driven rollers 6 of each driven component 3 is connected to one of the driving rollers 5 of the driving component 2 through a transmission component 7. The driving roller 5 is driven to rotate by the driving wheel, and then the driven roller 6 is driven to rotate through the transmission component 7, and then the driven wheel is driven to rotate, thereby realizing the synchronous rotation of the driven wheel and the driving wheel, simulating the driving state of the vehicle 4. Without the intervention of external force, the vehicle 4 cannot drive out of the display platform, which is safe and reliable.

[0031] Each driven component 3 can be connected to the same driving component 2 or to different driving components 2. In a specific embodiment of the present invention, two driving components 2 and two driven components 3 are provided, and the driving components 2 and the driven components 3 located on the same side are connected to each other in a transmission manner.

[0032] The driving roller 5 and the driven roller 6 may have different structures. If there is no special requirement, it is preferred that the two have the same structure to facilitate mass production. The specific structure of the driving roller 5 is described below by taking the driving roller 5 as an example.

[0033] Without considering the wheel deflection, the driving roller 5 can be a conventional cylindrical structure. However, the vehicle 4 often does not accurately travel in a straight line during autonomous driving, so it is usually necessary to correct the steering wheel. During the demonstration, when the vehicle 4 is idling, only the engine is working, and other equipment is not working. Therefore, it is necessary to correct the direction through the driving roller 5 and the driven roller 6. The correction method adopted by the utility model is (taking the driving roller 5 as an example): Figure 3 and Figure 4 As shown, a necking section 8 is provided in the middle of the driving roller 5, and the outer diameter of the necking section 8 is smaller than the outer diameter of the driving roller 5 at the axial ends of the necking section 8. During the rotation of the wheel, the necking section 8 can always guide the wheel toward its center, thereby preventing the wheel from escaping from the necking section 8 and driving out of the platform frame 1.

[0034] The necking section 8 may be composed of a diameter-changing inclined surface. Preferably, the outer peripheral surface of the necking section 8 is an arc-shaped structure that is gradually concave from the axial ends to the center.

[0035] In a further design, the driving roller 5 includes smooth sections 9 located at both ends of the necking section 8. The smooth section 9 is a cylindrical structure, and the outer diameter of the smooth section 9 is not less than the maximum outer diameter of the necking section 8. The design of the smooth section 9 can isolate the necking section 8 from the platform frame 1, thereby playing an isolation and buffering role, thereby preventing the wheel from rubbing against the platform frame 1 when reaching the edge of the necking section 8.

[0036] In order to reduce the cost and the quality of the driving roller 5 and reduce the torque loss, the driving roller 5 is preferably hollow inside, and support columns 10 are provided at both ends of the driving roller 5 to rotate with the platform frame 1. The driving roller 5 is rotatably connected to the platform frame 1 through a bearing, and the bearing sleeve is arranged on the support column 10.

[0037] The platform frame 1 can but is not limited to adopting the following structure: In the present embodiment, two groups of driving components 2 and driven components 3 are provided, and accordingly, the platform frame 1 includes two rails 101 arranged side by side and a connecting column 102 connecting the two rails 101, and each rail 101 is connected to a group of driving components 2 and driven components 3.

[0038] like Figure 1 and Figure 2As shown, the track 101 includes two longitudinal beams 1011 and a plurality of cross beams 1012 connecting the two longitudinal beams 1011. The driving roller 5 and the driven roller 6 are rotatably connected to the two longitudinal beams 1011. Since the wheels need to be trapped between the two driving rollers 5 and the two driven rollers 6, in order to avoid the collision between the chassis of the vehicle 4 and the cross beam 1012, it is preferred that the height of the highest point of the cross beam 1012 is lower than the height of the highest point of the driving roller 5 and the driven roller 6. Of course, the height of the cross beam 1012 can also be set slightly higher according to the characteristics of the vehicle model as long as it does not affect the rotation of the wheels.

[0039] The transmission assembly 7 may include sprockets installed on the driving roller 5 and the driven roller 6 and a chain connecting the two sprockets; or the transmission assembly 7 may include pulleys installed on the driving roller 5 and the driven roller 6 and a belt connecting the two pulleys.

[0040] The utility model can be used for the display of EV electric vehicles or fuel vehicles. When using fuel vehicles, the exhaust vibration may affect the exhibition hall environment. It is preferably used in the display of EV electric vehicles. EV electric vehicles have no exhaust emissions and no vibration in the idling state, and can be well used in various exhibition venues.

[0041] Embodiment 2

[0042] Based on the above embodiments, Figure 2 As shown, a protective cover 11 is provided on the outside of the platform frame 1, and the protective cover 11 includes a bottom plate 1101 and four side plates 1102, and the height of the side plates 1102 is slightly higher than the height of the platform frame 1. The "slightly higher" means that the height of the side plates 1102 is approximately equal to the height of the platform frame 1 or the height difference is not large, which plays a protective role on the platform frame 1, prevents impurities from entering, and prevents visitors from colliding with the platform frame 1.

[0043] A foot pad 13 (such as Figure 1 and Figure 5 The level can be adjusted according to the actual site.

[0044] Embodiment 3

[0045] Based on the above embodiment, the display stand further comprises a display box 12 made of a transparent material, and the display box 12 comprises an openable door 1201. The display box 12 is preferably made of glass material, such as Figure 5 As shown, other components of the display stand are located in the display box 12. When the door 1201 is closed, the vehicle 4 is enclosed in the display box 12, which provides good protection for the vehicle 4 and prevents the noise generated when the vehicle 4 is idling from affecting the viewing effect.

[0046] The door body 1201 can be connected to the box body by a hinge, and can be opened manually or by rotating the door body 1201 through a driving device (such as Figure 6 as shown).
