[0045] According to the floor assembly 100 provided by the embodiment of the present application, the support plate 4 is arranged, the structural strength and stability of the floor assembly 100 are enhanced, the support portion 41 on the support plate 4 provides support for the air duct 3, avoids damage and deformation of the air duct 3 due to excessive pressure, the support portion 41 ensures the safety of the air duct 3, and does not affect the installation and arrangement of other parts, and ensures that the overall structural design of the vehicle is reasonable, thereby avoiding affecting the structural integrity of the vehicle floor and improving the comfort of the vehicle.
[0046] In some embodiments of the present application, the support part 41 comprises a plurality of support parts 41 which are spaced apart. It can be understood that by providing a plurality of support parts 41 which are spaced apart on the support plate 4, the pressure can be dispersed, the wear and fatigue damage caused by local stress concentration can be reduced, the support to the air pipe 3 can be achieved, the air pipe 3 can be prevented from being subjected to heavy pressure, the plurality of support parts 41 can further improve the overall structural stability of the floor assembly 100, the risk caused by single-point failure can be reduced, the air pipe 3 can be effectively protected and supported, the protection and support effect can be improved, the probability of damage to the air pipe 3 can be reduced, and the cost of maintenance and replacement can be reduced.

[0050] In some embodiments of the present application, the cross-sectional area of each support portion 41 gradually decreases in the direction away from the floor body 1. It can be understood that the cross-sectional area of the support portion 41 close to the floor body 1 is greater than that of the support portion 41 away from the floor body 1. By designing the support portion 41 in the form of gradually decreasing cross-sectional area, the weight of the support portion 41 can be reduced without affecting the supporting effect, thereby reducing the weight of the support plate 4, which helps to improve fuel efficiency or the cruising range of electric vehicles. In addition, the larger cross-sectional area provides more contact surface, which can more evenly distribute the pressure applied on the support portion 41, avoiding deformation or damage caused by local stress concentration. The smaller cross-sectional area increases the distance between the two adjacent support portions 41, facilitating the assembly of the air pipe 3 into the through portion 43, and reducing the assembly difficulty.
[0051] Referring to Figure 2 and Figure 3 , the support portion 41 can be formed in a trapezoidal or circular frustum shape. The shape of the cross section of the support portion 41 can be circular, rectangular, pentagonal, hexagonal, etc. The change in the cross-sectional area of the support portion 41 is smoothly transitioned. In this way, the support area at the connection between the support portion 41 and the support plate 4 is ensured to be large enough, and the material used at the end of the support portion 41 away from the support plate 4 is reduced. Smooth transition avoids sudden changes or stress concentration points, ensuring the structural continuity and stability of the support portion 41.
[0052] In some embodiments of the present application, the support plate 4 is formed with a communication port 42, and the air port 31 of the air pipe 3 communicates with the communication port 42. It can be understood that the air port 31 of the air pipe 3 communicates with the communication port 42, and the arrangement position of the communication port 42 determines the air supply area of the air pipe 3, as shown in Figure 4 , the support plate 4 is formed with two communication ports 42, which are arranged at intervals. The air pipe 3 has two air ports 31, each corresponding to one communication port 42, and each air port 31 communicates with the corresponding communication port 42. This helps to distribute the airflow and optimize the airflow path.
[0053] Further, the communication port 42 can be formed in a circular or rectangular shape, and the shape and size are matched with the air hole of the air pipe 3. The edge of the communication port 42 is formed with a flange or flange treatment to enhance the connection sealing performance.
[0054] Since the density of the expanded polypropylene material (EPP) is small and the compressive strength is high, the honeycomb closed cell structure can cyclically absorb impact energy, which is beneficial for cushioning and protection. In addition, it has good weather resistance, waterproofness, moisture resistance, environmental protection and recyclability. Therefore, the support plate 4 is formed of expanded polypropylene material, thereby improving the structural strength of the support plate 4 and ensuring the energy absorption and shock absorption effect of the support plate 4.

Thus, the vibration transmitted from the ground to the vehicle compartment is reduced, and the support plate 4 is protected from external impact.
[0057] In some embodiments of the present application, the damping member 2 is formed with a containing area 21, and the damping member 2 covers the air pipe 3 in the containing area 21. It can be understood that the damping member 2 is used to absorb the vibration from the ground and reduce the vibration transmitted to the vehicle compartment, and at the same time, the damping member 2 plays a role of sound insulation, reduces the external noise into the vehicle compartment, and improves the riding comfort.

Thus, the vibration transmitted from the ground to the vehicle compartment is reduced, and the support plate 4 is protected from external impact.
[0058] Further, the damping member 2 plays a role of sound insulation and noise reduction while absorbing and dispersing vibration energy, the air pipe 3 is arranged in the damping member 2, connected with the air conditioning system of the vehicle, and communicates with the air outlet 31 of the air conditioner, the air pipe 3 is used to adjust the temperature and air quality in the vehicle, the air pipe 3 is arranged in the damping member 2, the damping member 2 plays a role of damping and isolating the airflow noise in the air pipe 3, and the damping member 2 cooperates with the support plate 4 to avoid damage and deformation of the air pipe 3.

By designing the support portion 41 to gradually decrease in cross-sectional area, the weight of the support portion 41 can be reduced without affecting the supporting effect, thereby reducing the weight of the support plate 4, which helps to improve fuel efficiency or the cruising range of an electric vehicle. In addition, the larger cross-sectional area provides more contact area, which can more evenly distribute the pressure applied to the support portion 41, avoiding deformation or damage caused by local stress concentration. The smaller cross-sectional area increases the distance between the two adjacent support portions 41, facilitating the assembly of the air pipe 3 into the passing portion 43, and reducing the assembly difficulty.
