Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Generally speaking, the ventilation ducts of the rear seat cushions (non-sliding) of a car are arranged by using the gap between the back or sides of the seat and the car body, which requires a thicker seat cushion. When the seat cushion is thin, using this method to arrange the ventilation ducts will make heavier passengers feel hard when sitting on the seat, and the comfort is poor.

[0036] In view of this, the present invention proposes a rear floor assembly, see Figures 1 to 9 , is an embodiment of the rear floor assembly, and the rear floor assembly will be described in detail below with reference to specific drawings.

[0037] See also Figures 1 to 9 The rear floor assembly 1000 includes a front crossbeam assembly 100 and a rear floor 200. The front crossbeam assembly 100 includes a main body 1 and a partition 2 placed in the main body 1. The main body 1 is hollow, with an air outlet 11 on the top and an air inlet 12 on the front side. The partition 2 and the main body 1 are combined to form an air duct 3. The air outlet 11 and the air inlet 12 are connected to the air duct 3; the front end of the rear floor 200 is overlapped on the top of the main body 1.

[0038] In the technical solution of the present invention, the ventilation duct 3 of the seat 2000 is formed mainly by adjusting the vehicle body beam structure, without arranging additional plastic parts to form the duct 3. On the one hand, it solves the problem that when the seat cushion is thin, plastic parts cannot be arranged to form the duct 3. That is, the duct 3 structure directly formed by the vehicle body beam can be used on models with thinner seat cushions. There will be no foreign body feeling caused by the protruding structure, and it is comfortable. On the other hand, the duct 3 formed by the vehicle body beam structure will not be deformed after painting and baking, and the structure is stable, so that it has stable ventilation efficiency.

[0039] Specifically, the front crossbeam assembly 100 includes a hollow main body 1 and a partition 2 disposed within the main body 1. The main body 1 forms a hollow structure, while the partition 2 encloses the air duct 3. This utilizes the vehicle body beam structure to form the air duct 3, achieving the aforementioned beneficial effects. Furthermore, the air outlet 11 is provided at the top of the main body 1 to correspond to the seat 2000, and the air inlet 12 is provided on the front side of the main body 1 to correspond to the footrest space of the rear seat 2000, providing a relatively open and less obstructed space. The partition 2 not only encloses the air duct 3, but also, being fixed within the main body 1, reinforces the structural strength of the front crossbeam assembly 100. This arrangement satisfies the structural requirements of this application, while also simplifying the structure of the rear floor assembly 1000 and enhancing its practicality.

[0040] Specifically, the edges of the partition 2 are welded to the main body 1, and a sealant is applied to the welds. The partition 2 can be connected to the main body 1 in a variety of ways, including but not limited to riveting, screwing, or welding. In this embodiment, the partition 2 is welded to the main body 1. This not only eliminates the need for additional fixing structures on the vehicle body beam, but also facilitates sealing and enhances structural strength. To ensure sealing, the sealant is also applied to the welds in this embodiment.

[0041] In addition, a positioning protrusion is provided in the main body 1, and a positioning hole is correspondingly provided on the partition 2. The positioning hole cooperates with the positioning protrusion, and a blocking cover is provided at the positioning hole. When the partition 2 is fixed on the main body 1, it needs to be positioned to ensure the accuracy of the welding point, thereby ensuring the accuracy of the structure of the air duct 3 and the structural strength of the main body 1. There are many positioning structures that can be set, including but not limited to positioning grooves, positioning holes, etc. In this embodiment, in order to avoid affecting the NVH performance of the whole vehicle, only the positioning hole is opened on the partition 2 for positioning, and after the positioning hole is positioned in coordination with the positioning protrusion, the partition 2 is welded. After the welding and fixing are completed, the blocking cover needs to be covered at the positioning hole to play a sealing role, ensure the sealing performance, avoid noise after ventilation in the air duct 3, and ensure the NVH performance of the whole vehicle.

[0042] In addition, a decorative cover 4 is provided at the air inlet 12, and a vent 41 is formed on the decorative cover 4. As described above, the air inlet 12 corresponds to the footrest space of the rear seat 2000. Therefore, the air inlet 12 is located on the exterior surface of the rear row. To avoid affecting the overall appearance of the vehicle and to provide dust protection, this embodiment further provides the decorative cover 4 at the air inlet 12, and the vent 41 is formed on the decorative cover 4 to allow air to enter through the air inlet 12.

[0043] Furthermore, a shielding plate 42 is provided at the vent 41, and the shielding plate 42 is tilted upward from front to back. It is understandable that when a user gets on the vehicle, their line of sight may be directed from top to bottom toward the decorative cover plate 4. To prevent the user from observing the vent 41 and the air duct 3 behind the vent 41, this embodiment further provides a plurality of shielding plates 42 spaced from top to bottom at the vent 41, and the shielding plates 42 are arranged to tilt upward from front to back. This allows the user to observe only the surface of the shielding plates 42 from top to bottom, but not the gaps between them, and thus the structure of the vent 41, further ensuring aesthetics.

[0044] Furthermore, the size of the vent 41 is not smaller than the size of the air outlet 11. To ensure the stability of the air intake of the air duct 3 and prevent the air intake 12 from being too small, which would affect the air output of the air outlet 11, the size of the air intake 12 must be not smaller than the size of the air outlet 11. In the above embodiment, the decorative cover 4 is also provided at the air intake 12 to allow air to enter through the vent 41 on the decorative cover 4. Therefore, the size of the vent 41 is further limited to not smaller than the size of the air outlet 11 to ensure the ventilation volume of the seat 2000 and thus the ventilation performance of the seat 2000.

[0045] In addition, the front end of the rear floor 200 overlaps the top of the main body 1, and in order to avoid the front end of the rear floor 200 being too close to the air outlet 11, which makes the air duct 3 difficult to seal or even impossible to seal, in this embodiment, the distance between the overlap and the air outlet 11 is set to be no less than 15 mm, that is, the distance is A, then A≥15 mm.

[0046] The present invention also provides a vehicle comprising a rear floor assembly 1000 and a seat 2000. The specific structure of the rear floor assembly 1000 is similar to the above-described embodiment. Since the vehicle adopts all the technical solutions of all the above-described embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-described embodiments, which will not be described in detail here. The seat 2000 is arranged above the rear floor assembly 1000. To prevent the front end of the seat 2000 from being too close to the air outlet 11, resulting in a gap and affecting the appearance, in this embodiment, the distance between the front end of the seat 2000 and the air outlet 11 is set to be no less than 20 mm, that is, the distance is B, and B ≥ 20 mm. A fan 3000 is also provided at the bottom of the seat 2000 corresponding to the air outlet 11 to drive airflow and achieve a ventilation effect for the seat 2000.

[0047] In addition, the car is provided with a carpet in front of the seat 2000, and in order to prevent the passenger's heels from approaching or even blocking the air inlet 12 when sitting on or stepping on the carpet, in this embodiment, the height of the air inlet 12 from the carpet is set to be not less than 100 mm, that is, the height difference between the carpet and the air inlet 12 is C, then C≥100 mm.

[0048] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
