Referring to FIGS. 1 to 4 , the front floor assembly 100 of the embodiment of the utility model is used for a vehicle 1000, and the front floor assembly 100 includes a central channel 10, a first sealing beam 22, two second sealing beams 24, and a third sealing beam 25. The first sealing beam 22 is connected to the central channel 10, and the two second sealing beams 24 are spaced apart along the Y direction of the vehicle 1000. The two ends of the second sealing beam 24 are respectively connected to the first sealing beam 22 and the third sealing beam 25. The first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 are split structures and jointly define a sealing surface 21, which faces away from the passenger compartment of the vehicle 1000, and is used for sealing connection with the battery pack 700 of the vehicle 1000.

In the front floor assembly 100 of the embodiment of the utility model, the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 jointly define a sealing surface 21; the sealing surface 21 can seal the battery pack 700 of the vehicle 1000, thereby reducing the probability of contaminants entering the battery pack 700, and further reducing the probability of functional failure of the battery pack 700. In addition, the material utilization rate of this split sealing surface 21 is high, so that the manufacturing cost of the sealing surface 21 is low.

Specifically, the front floor assembly 100 is an important component located at the bottom of the vehicle 1000, and the front floor assembly 100 can carry the front seats arranged in the passenger compartment 800 of the vehicle 1000. The central channel 10 is a component of the front floor assembly 100, and the central channel 10 can be a channel structure including a plurality of sheet metal parts, and the central channel 10 can be arranged in the middle of the front floor assembly 100 along the Y direction of the vehicle 1000 (the width direction of the vehicle 1000).

The cross section of the first sealing beam 22 may be in a regular shape such as a U-shape or an L-shape, or in an irregular shape. The shape of the first sealing beam 22 should be adapted to the shape of the central channel 10, so as to facilitate the connection between the first sealing beam 22 and the central channel 10. The first sealing beam 22 and the central channel 10 may be connected by threaded connection, welding, etc. For example, the first sealing beam 22 and the central channel 10 may be designed to have corresponding threads and threaded holes so that they can be threaded together.

It is understood that the threaded connection in the above embodiment can also be replaced by welding or bonding, and the first sealing beam and the central channel 10 can be connected by welding or bonding. This connection method can improve the connection rigidity between the first sealing beam and the central channel 10, and has better sealing performance.

The shapes of the two second sealing beams 24 may be the same or different. The second sealing beam 24 may be connected to the first sealing beam 22 by threaded connection, welding, etc. Along the Y direction of the vehicle 1000, the first sealing beam 22 may be in a long strip shape. The two second sealing beams 24 may be connected to the two ends of the first sealing beam 22 by welding, and the two second sealing beams 24 may form right angles with the two ends of the first sealing beam 22.

The third sealing beam 25 can be in the shape of a long strip. Along the Y direction of the vehicle 1000, the third sealing beam 25 can connect the ends of the two second sealing beams 24. The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can form a square-shaped structure. The connection between the third sealing beam 25 and the second sealing beam 24 can be threaded connection, welding, etc. The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can be connected to each other to jointly define the sealing surface 21. The sealing surface 21 defined in this way is a split structure.

The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can be processed and manufactured independently. In this way, the split structure formed by processing the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 has a high material utilization rate and a low cost. After the processing is completed, the independent first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can be connected end to end by threaded connection, welding, etc., so as to define the sealing surface 21. For example, the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 are obtained by independent processing and manufacturing, and the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 are connected end to end in a certain shape, so as to define the sealing surface 21.

The shape formed by the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can be a regular shape, such as a square, or an irregular shape. The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 connected end to end can be respectively arranged in multiple different directions of the central channel 10, so that the central channel 10 is partially or completely located within the space defined by the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25. The connection between the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can be threaded connection, welding, etc.

The sealing surface 21 may be a surface on the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 that faces the battery pack 700. The battery pack 700 may include a battery cover that may isolate the internal environment of the battery pack 700 from the external environment. The battery pack 700 may be disposed at the bottom of the vehicle 1000, and further, the battery pack 700 may be disposed below the passenger compartment 800 of the vehicle 1000. Accordingly, the sealing surface 21 may be disposed facing away from the passenger compartment 800 of the vehicle 1000.

The surface of the battery cover facing the sealing surface 21 can be in contact with the sealing surface 21, and further, the edge of the surface of the battery cover facing the sealing surface 21 can be in contact with the sealing surface 21, thereby preventing contaminants from entering the interior of the battery pack 700. The sealing surface 21 and the battery cover can be in contact with each other by welding or bonding. For example, multiple weldings can be performed in the connection area between the battery cover and the sealing surface 21. For another example, a sealant can be used for bonding in the connection area between the battery cover and the sealing surface 21.

Please refer to FIGS. 3 , 4 and 5 . In some embodiments, the first sealing beam 22 extends along the Y direction of the vehicle 1000 and forms a first sealing surface 210 . The first sealing surface 210 extends along the Y direction of the vehicle 1000 . The sealing surface 21 includes the first sealing surface 210 .

In this way, the central channel 10 is a fixed structure on the vehicle body. The connection between the first sealing beam 22 and the central channel 10 can improve the structural strength of the first sealing beam 22, thereby improving the sealing stability of the first sealing beam 22. During the driving process of the vehicle 1000, different vibrations and pressures may be encountered. The first sealing beam 22 extending along the Y direction of the vehicle 1000 can adapt to different vibrations and pressures, thereby improving the service life of the first sealing beam 22.

Specifically, the central channel 10 may be along the X direction of the vehicle 1000 (the driving direction of the vehicle 1000), and the first sealing beam 22 may extend along the Y direction of the vehicle 1000, that is, the angle formed between the first sealing beam 22 and the central channel 10 may be a right angle, which is beneficial to the transmission of force during the driving of the vehicle 1000, reduces the vibration of the first sealing beam 22, and thus can improve the service life of the first sealing beam 22. Along the Z direction of the vehicle 1000 (the height direction of the vehicle 1000), the first sealing beam 22 may be arranged below the central channel 10, and the first sealing surface 210 may be the outer surface of the first sealing beam 22 that is away from the central channel 10.

Referring to FIGS. 3 , 4 and 5 , in certain embodiments, the front floor assembly 100 further includes a reinforcement member 23 connected to the central channel 10 and the first sealing beam 22 , and the reinforcement member 23 is disposed away from the first sealing surface 210 .

In this way, the reinforcement member 23 can improve the connection strength between the central channel 10 and the first sealing beam 22, improve the sealing stability of the first sealing beam 22, and thus improve the sealing stiffness of the first sealing surface 210. The reinforcement member 23 is arranged away from the first sealing surface 210 to avoid the reinforcement member 23 affecting the sealing function of the first sealing surface 210.

Specifically, the reinforcement 23 may be a sheet metal part, and a cavity 101 (as shown in FIG. 5 ) may be formed between the reinforcement 23 and the first sealing beam 22, thereby improving the overall structural rigidity of the reinforcement 23 and the first sealing beam 22. The reinforcement 23 may be connected to the central channel 10 and the first sealing beam 22 respectively by welding, threaded connection, etc. For example, the reinforcement 23 may be connected to the surface of the first sealing beam 22 away from the first sealing surface 210 by welding, and may be connected to the central channel 10 by welding.

Please refer to FIG. 2 , FIG. 5 and FIG. 6 . In some embodiments, the reinforcement 23 includes a first reinforcement 230 and a second reinforcement 231 . Along the Y direction of the vehicle 1000 , the first reinforcement 230 and the second reinforcement 231 are respectively connected to both sides of the central channel 10 .

In this way, along the Y direction of the vehicle 1000, the first reinforcement 230 and the second reinforcement 231 can cooperate with the first sealing beam 22, and the first reinforcement 230 and the second reinforcement 231 can respectively support the two sides of the central channel 10, thereby realizing a symmetrical and uniform support structure, thereby improving the connection strength between the first sealing beam 22 and the central channel 10, and then improving the sealing stability of the first sealing beam 22.

Specifically, the first reinforcement 230 and the second reinforcement 231 can be two sheet metal parts manufactured separately, and the shapes of the first reinforcement 230 and the second reinforcement 231 can be consistent or inconsistent. The cross section of the central channel 10 can be rectangular, and the first reinforcement 230 and the second reinforcement 231 can be connected to two opposite sides of the rectangular. The first reinforcement 230 and the second reinforcement 231 can be connected to the central channel 10 by welding, threading, etc.

5 , in some embodiments, a cavity 101 is formed between the first reinforcement member 230 , the second reinforcement member 231 and the first sealing beam 22 . In this way, the cavity 101 can act as an “air spring” to buffer external loads and improve the rigidity and stability of the first reinforcement member 230 , the second reinforcement member 231 and the first sealing beam 22 as a whole.

Specifically, when an external load acts on the structure composed of the first reinforcement member 230, the second reinforcement member 231 and the first sealing beam 22, the air in the cavity 101 is squeezed to form a compressed state similar to a spring. This compressed state increases the pressure inside the air, thereby achieving a buffering effect on the external load.

This buffering effect can effectively reduce the impact of external loads on the first reinforcement 230, the second reinforcement 231 and the first sealing beam 22 as a whole, and improve their rigidity and stability. Since air is compressible, this buffering effect can adapt to changes in external loads within a certain range, making the entire component more stable and reliable when bearing external loads.

1 and 3 , in some embodiments, the first sealing beam 22 is connected to the dash assembly 200 of the vehicle 1000. In this way, the dash assembly 200 of the vehicle 1000 can provide support for the first sealing beam 22, thereby improving the structural strength of the first sealing beam 22 and further improving the sealing stability of the first sealing beam 22.

Specifically, the connection between the first sealing beam 22 and the front panel assembly 200 of the vehicle 1000 can be welding, threaded connection, etc. For example, the first sealing beam 22 and the front panel assembly 200 can be designed to have corresponding threads and threaded holes so that they can be threaded together.

Please refer to FIG. 3 , FIG. 4 and FIG. 7 . In some embodiments, the two second sealing beams 24 extend along the X-direction of the vehicle 1000 and form two second sealing surfaces 211 . The second sealing surfaces 211 extend along the X-direction of the vehicle 1000 . The second sealing surfaces 211 are connected to the first sealing surfaces 210 .

In this way, the second sealing surface 211 is connected to the first sealing surface 210, which can form a continuous sealing structure, thereby improving the overall sealing performance of the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25. The two second sealing beams 24 are arranged at intervals along the Y direction of the vehicle 1000 to provide a larger sealing range, thereby adapting to the sealing requirements of battery packs 700 of different shapes and sizes.

Specifically, the two second sealing beams 24 may extend along the X direction of the vehicle 1000, and the second sealing surfaces 211 may be formed on the surfaces of the two second sealing beams 24 facing the same direction as the first sealing surface 210. The second sealing surface 211 and the first sealing surface 210 may contact each other, and the adjacent areas of the second sealing surface 211 and the first sealing surface 210 may be coplanar, thereby improving the continuity of the seal.

Please refer to Figures 2, 4 and 6. In some embodiments, one of the second sealing beams 24 includes a left sill inner panel 102 of the vehicle 1000 and a first flange 240, and the first flange 240 is arranged on the left sill inner panel 102. The other second sealing beam 24 includes a right sill inner panel 103 of the vehicle 1000 and a second flange 241, and the second flange 241 is arranged on the right sill inner panel 103. The left sill inner panel 102 is connected to the left sill beam 400 of the vehicle 1000, and the right sill inner panel 103 is connected to the right sill beam 500 of the vehicle 1000. The first flange 240 and the second flange 241 both extend along the X-direction of the vehicle 1000, and the first flange 240 and the second flange 241 both form a second sealing surface 211.

In this way, the second sealing surface 211 is formed by adding the first flange 240 and the second flange 241 to the left sill inner panel 102 and the right sill inner panel 103 of the vehicle 1000, without adding additional parts, thereby reducing the manufacturing cost. In addition, the left sill inner panel 102 and the right sill inner panel 103 forming the second sealing surface 211 have a high structural strength, which is conducive to the stability of the seal.

Specifically, the shapes of the first flange 240 and the second flange 241 may be the same or different. The left sill inner plate 102 and the right sill inner plate 103 may be connected to the left sill beam 400 and the right sill beam 500 respectively by FDS (Flow Drill Screw) process, thereby improving the rigidity of the connection and further improving the sealing stability of the second sealing surface 211.

3 , in some embodiments, the second sealing beam 24 is connected to the seat cross beam 300 of the vehicle 1000. In this way, the seat cross beam 300 of the vehicle 1000 can provide support for the second sealing beam 24, thereby improving the structural strength of the second sealing beam 24 and further improving the sealing stability of the second sealing beam 24.

Specifically, the second sealing beam 24 and the seat cross beam 300 of the vehicle 1000 may be connected by welding, threaded connection, etc. For example, the second sealing beam 24 and the seat cross beam 300 may be provided with a plurality of corresponding welding points, and the second sealing beam 24 and the seat cross beam 300 are connected by welding points and solder.

Please refer to FIG. 4 and FIG. 8 . In some embodiments, the third sealing beam 25 extends along the Y direction of the vehicle 1000 and forms a third sealing surface 212 . The third sealing surface 212 extends along the Y direction of the vehicle 1000 . The third sealing surface 212 is connected to the second sealing surface 211 .

In this way, the third sealing surface 212 is connected to the second sealing surface 211 , which can form a continuous sealing structure, thereby improving the overall sealing performance of the first sealing beam 22 , the two second sealing beams 24 and the third sealing beam 25 .

Specifically, the third sealing beam 25 and the second sealing surface 211 may form a third sealing surface 212 on the same surface. The third sealing surface 212 and the second sealing surface 211 may contact each other, and the adjacent areas of the third sealing surface 212 and the second sealing surface 211 may be coplanar, thereby improving the continuity of the seal.

4 , in some embodiments, the third sealing beam 25 is connected to the rear floor front cross beam 600 of the vehicle 1000. In this way, the rear floor front cross beam 600 of the vehicle 1000 can provide support for the third sealing beam 25, thereby improving the structural strength of the third sealing beam 25, and further improving the sealing stability of the third sealing beam 25.

Specifically, along the Z direction of the vehicle 1000, the third sealing beam 25 may be disposed below the rear floor front cross beam 600 of the vehicle 1000. The third sealing beam 25 and the rear floor front cross beam 600 of the vehicle 1000 may be connected by welding, threaded connection, etc. For example, a plurality of corresponding welding points may be disposed on the third sealing beam 25 and the rear floor front cross beam 600, and the connection between the third sealing beam 25 and the rear floor front cross beam 600 is achieved through welding points and solder.
