[0035] Generally speaking, the ventilation duct of the rear seat cushion (non-sliding type) of a car is through the gap between the back or both 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 duct will make the seat feel hard and uncomfortable for heavier passengers.

[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 cross beam assembly 100 and a rear floor 200. The front cross beam assembly 100 includes a main body 1 and a partition 2 placed in the main body 1. The main body 1 is hollow and has an air outlet 11 on the top and an air inlet 12 on the front. 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 by utilizing the body beam structure mainly by adjusting the 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 body beam can be used in vehicles with thinner seat cushions. There will be no foreign body sensation caused by the protruding structure, and it is comfortable. On the other hand, the duct 3 formed by the 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 cross beam assembly 100 includes the hollow main body 1 and the partition 2 arranged in the main body 1, that is, the main body 1 is used to form a cavity structure, and the partition 2 is used to enclose and form the air duct 3, so that the air duct 3 is formed by using the body beam structure to have the above-mentioned beneficial effects. In addition, the air outlet 11 is arranged on the top of the main body 1 to correspond to the seat 2000, and the air inlet 12 is opened on the front side of the main body 1 to correspond to the foot pad space of the rear seat 2000, which is relatively open and not easily blocked. The partition 2 is used to enclose and form the air duct 3 on the one hand, and is fixed in the main body 1 on the other hand, and also plays a role in strengthening the structural strength of the front cross beam assembly 100. Such a configuration can meet the structural characteristics required by the present application, and the rear floor assembly 1000 has a simple structure and is more practical.

[0040] Specifically, the edge of the partition 2 is welded and fixed to the main body 1, and a sealant is applied to the weld. The partition 2 and the main body 1 can be connected in a variety of ways, including but not limited to riveting, screwing or welding. In this embodiment, the partition 2 is welded and fixed to the main body 1. On the one hand, there is no need to add a fixed structure to the vehicle body beam, and on the other hand, it is easy to seal and has a high structural strength. For sealing, the sealant is also applied to the weld 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 the noise generated after ventilation in the air duct 3, so as to ensure the NVH performance of the whole vehicle.

[0042] In addition, a decorative cover plate 4 is provided at the air inlet 12, and a vent 41 is provided on the decorative cover plate 4. The air inlet 12 corresponds to the foot pad space of the rear seat 2000, which has been described above. Therefore, the air inlet 12 is located on the exterior surface of the rear seat. In order to avoid affecting the appearance of the entire vehicle and to play a dust-proof role, the present embodiment further provides the decorative cover plate 4 at the air inlet 12, and the vent 41 is provided on the decorative cover plate 4 for air to enter from 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, his / her line of sight may be directed from top to bottom to the decorative cover plate 4. To prevent the user from observing the vent 41 and the air duct 3 behind the vent 41, the present 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 be tilted upward from front to back, so that the user can only observe the plate surface of the shielding plates 42 from top to bottom, but cannot observe the gaps between them, and thus cannot observe the structure of the vent 41, thereby further ensuring aesthetics.

[0044] In addition, the size of the vent 41 is not less than the size of the air outlet 11. In order to ensure the stability of the air intake of the air duct 3 and avoid the air intake 12 being too small to affect the air outlet 11, the size of the air intake 12 needs to be not less than the size of the air outlet 11. In the above embodiment, the decorative cover plate 4 is also provided at the air intake 12 to allow air to enter through the vent 41 on the decorative cover plate 4. Therefore, the size of the vent 41 is further limited to be not less than the size of the air outlet 11 to ensure the ventilation volume of the seat 2000 and 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 prevent the front end of the rear floor 200 from 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 not less than 15mm, that is, the distance is A, then A≥15mm.

[0046] The present invention also proposes a car, which includes a rear floor assembly 1000 and a seat 2000. The specific structure of the rear floor assembly 1000 refers to the above embodiment. Since the car adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The seat 2000 is arranged above the rear floor assembly 1000, and in order to avoid the front end of the seat 2000 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 not less than 20mm, that is, the distance is B, then B≥20mm. A fan 3000 is also arranged at the bottom of the seat 2000 corresponding to the position of the air outlet 11, which is used to drive the airflow to achieve the ventilation effect of 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 heels of the passengers from approaching or even blocking the air inlet 12 when the passengers sit on and step 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, and C≥100 mm.

[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
