Referring to fig. 1 to 4, a front floor assembly 100 according to an embodiment of the present utility model is used for a vehicle 1000, and the front floor assembly 100 includes a central tunnel 10, a first seal beam 22, two second seal beams 24, and a third seal beam 25. The first sealing beam 22 is connected with the central channel 10, the two second sealing beams 24 are arranged at intervals along the Y direction of the vehicle 1000, two ends of each second sealing beam 24 are respectively connected with 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 of split type structures and jointly define a sealing surface 21, the sealing surface 21 faces away from a cabin of the vehicle 1000, and the sealing surface 21 is used for being in sealing connection with a battery pack 700 of the vehicle 1000.

In the front floor assembly 100 of the embodiment of the present utility model, the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 together define the 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 thus reducing the probability of functional failure of the battery pack 700. In addition, the utilization rate of the material of the split type 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 underbody of the vehicle 1000, and the front floor assembly 100 may carry front seats disposed within the passenger compartment 800 of the vehicle 1000. The central tunnel 10 is an integral part of the front floor assembly 100, and the central tunnel 10 may be a tunnel structure including a plurality of sheet metal members, and the central tunnel 10 may be disposed at a central portion of the front floor assembly 100 in 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 may be in an irregular shape. The shape of the first sealing beam 22 should be adapted to the shape of the central channel 10 in order to facilitate the connection of the first sealing beam 22 to the central channel 10. The first sealing beam 22 may be connected to the central passage 10 by a threaded connection, welding, or the like. For example, the first sealing beam 22 and the central passage 10 may be designed with corresponding threads and threaded holes so that they may be screwed together.

It will be appreciated that the threaded connection in the above embodiments may also be replaced by welding or bonding, and that the first sealing beam and the central passage 10 may be connected by welding or bonding, etc. This way of connection can promote the rigidity of the connection between the first sealing beam and the central passage 10 and the tightness is better.

The shape of the two second sealing beams 24 may or may not be identical. The second sealing beam 24 may be connected to the first sealing beam 22 by screwing, welding, or the like. The first seal beam 22 may be elongated in the Y direction of the vehicle 1000. The two second sealing beams 24 may be connected to both ends of the first sealing beam 22 by welding, and the two second sealing beams 24 may form right angles with both ends of the first sealing beam 22, respectively.

The third sealing beam 25 may be elongated, and along the Y direction of the vehicle 1000, the third sealing beam 25 may connect the ends of the two second sealing beams 24, and the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 may enclose a square-like structure. The connection between the third sealing beam 25 and the second sealing beam 24 may be a threaded connection, welding, etc. The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 can jointly define the sealing surface 21 by being connected to each other, the sealing surface 21 defined in this way being of a split construction.

The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 may be machined 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 higher material utilization rate and lower cost. After the machining is completed, the independent first sealing beam 22, two second sealing beams 24 and a third sealing beam 25 may be connected end to end by means of threaded connection, welding or the like, thereby defining the sealing surface 21. For example, the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 are independently machined and manufactured, and the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 are joined end to end in a certain shape, thereby defining the sealing surface 21.

The shape enclosed by the first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25 may be a regular shape, such as a square shape, or an irregular shape. The first sealing beam 22, the two second sealing beams 24 and the third sealing beam 25, which are connected end to end, may be arranged in a plurality of different directions of the central passage 10, respectively, such that the central passage 10 is partly or entirely 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 may be a threaded connection, a welding, etc.

The sealing surface 21 may be the surface of the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 facing 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 under the passenger compartment 800 of the vehicle 1000. Accordingly, the sealing surface 21 may be disposed away from the passenger compartment 800 of the vehicle 1000.

The surface of the battery cover facing the sealing surface 21 may be fitted with the sealing surface 21, and further, the edge of the surface of the battery cover facing the sealing surface 21 may be fitted with the sealing surface 21, thereby preventing contaminants from entering the inside of the battery pack 700. The sealing surface 21 and the battery cover can be bonded by welding or adhesion. For example, a plurality of welds may be performed in the connection region of the battery cover and the sealing surface 21. For another example, a sealant may be used for bonding in the connection region between the battery cover and the sealing surface 21.

Referring to fig. 3, 4 and 5, in some embodiments, the first seal rail 22 extends along the Y-direction of the vehicle 1000 and forms a first seal surface 210, the first seal surface 210 extending along the Y-direction of the vehicle 1000, and the seal surface 21 includes the first seal surface 210.

Thus, the central passage 10 is a fixed structure on the vehicle body. The connection of the first sealing beam 22 with the central passage 10 can improve the structural strength of the first sealing beam 22, thereby improving the sealing stability of the first sealing beam 22. Different vibrations and pressures may be encountered during the travel of the vehicle 1000, and the extension of the first seal beam 22 in the Y-direction of the vehicle 1000 may accommodate the different vibrations and pressures, thereby improving the service life of the first seal beam 22.

Specifically, the central passage 10 may extend in the X direction of the vehicle 1000 (the traveling direction of the vehicle 1000), and the first sealing beam 22 may extend in the Y direction of the vehicle 1000, i.e., the angle formed between the first sealing beam 22 and the central passage 10 may be a right angle, which is advantageous for the transmission of force of the vehicle 1000 during traveling, and reduces vibration of the first sealing beam 22, thereby being capable of improving the service life of the first sealing beam 22. In the Z-direction of the vehicle 1000 (the height direction of the vehicle 1000), the first sealing beam 22 may be disposed below the central passage 10, and the first sealing surface 210 may be an outer surface of the first sealing beam 22 facing away from the central passage 10.

Referring to fig. 3, 4 and 5, in some embodiments, the front floor assembly 100 further includes a stiffener 23 coupled to the central passage 10 and the first sealing beam 22, the stiffener 23 being disposed away from the first sealing surface 210.

In this way, the reinforcement 23 can enhance the connection strength between the central passage 10 and the first sealing beam 22, and enhance the sealing stability of the first sealing beam 22, thereby enhancing the sealing rigidity of the first sealing surface 210. The provision of the reinforcement member 23 away from the first sealing surface 210 can avoid the influence of the reinforcement member 23 on the sealing function of the first sealing surface 210.

Specifically, the reinforcement member 23 may be a sheet metal member, and the reinforcement member 23 may form a cavity 101 (as shown in fig. 5) with the first seal beam 22 therebetween, thereby improving the structural rigidity of the reinforcement member 23 and the first seal beam 22 as a whole. The reinforcement 23 may be connected to the central passage 10 and the first sealing beam 22, respectively, by welding, screwing, etc. For example, the reinforcement 23 may be welded to the surface of the first sealing beam 22 facing away from the first sealing surface 210 and may be welded to the central channel 10.

Referring to fig. 2, 5 and 6, in some embodiments, the reinforcement 23 includes a first reinforcement 230 and a second reinforcement 231, and the first reinforcement 230 and the second reinforcement 231 are respectively connected to both sides of the central passage 10 in the Y direction of the vehicle 1000.

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

Specifically, the first reinforcement 230 and the second reinforcement 231 may be two sheet metal parts manufactured separately, and the shapes of the first reinforcement 230 and the second reinforcement 231 may or may not be identical. The central passage 10 may have a rectangular-like shape in cross section, and the first reinforcement 230 and the second reinforcement 231 may be connected at opposite sides of the rectangular-like shape. The first reinforcement 230 and the second reinforcement 231 may be coupled to the central passage 10 by welding, screwing, or the like.

Referring to fig. 5, in some embodiments, the first reinforcement 230, the second reinforcement 231, and the first sealing beam 22 enclose a cavity 101 therebetween. In this manner, the cavity 101 may act as an "air spring" to cushion external loads, improving the rigidity and stability of the first reinforcement 230, the second reinforcement 231, and the first sealing beam 22 as a whole.

Specifically, when an external load is applied to the structure composed of the first reinforcement 230, the second reinforcement 231, and the first sealing beam 22, the air in the cavity 101 is compressed to form a compressed state resembling a spring. This compressed state increases the pressure inside the air, thereby achieving a cushioning effect against external loads.

Such a buffering effect can effectively reduce the influence of external load on the whole of the first reinforcement 230, the second reinforcement 231 and the first sealing beam 22, improving the rigidity and stability thereof. Because of the compressibility of air, this cushioning effect can accommodate a range of external load changes, making the entire component more stable and reliable when subjected to external loads.

Referring to fig. 1 and 3, in some embodiments, the first sealing beam 22 is coupled to a front wall assembly 200 of the vehicle 1000. In this manner, the front wall 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 wall assembly 200 of the vehicle 1000 may be welding, screw connection, or the like. For example, the first sealing beam 22 and the front wall assembly 200 may be configured with corresponding threads and threaded holes so that they may be threadably coupled together.

Referring to fig. 3, 4 and 7, in some embodiments, 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 extending along the X-direction of the vehicle 1000, the second sealing surfaces 211 connecting the first sealing surfaces 210.

In this way, the second sealing surface 211 connects the first sealing surfaces 210, which can form a continuous sealing structure, thereby improving the sealing performance of the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 as a whole. The spacing of the two second sealing beams 24 along the Y-direction of the vehicle 1000 can provide a large sealing range to accommodate the sealing requirements of different shape and size battery packs 700.

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

Referring to fig. 2, 4 and 6, in some embodiments, one of the second seal beams 24 includes a left rocker inner panel 102 and a first flange 240 of the vehicle 1000, the first flange 240 is disposed on the left rocker inner panel 102, the other second seal beam 24 includes a right rocker inner panel 103 and a second flange 241 of the vehicle 1000, the second flange 241 is disposed on the right rocker inner panel 103, the left rocker inner panel 102 is connected with a left rocker beam 400 of the vehicle 1000, the right rocker inner panel 103 is connected with a right rocker beam 500 of the vehicle 1000, the first flange 240 and the second flange 241 each extend along an X-direction of the vehicle 1000, and the first flange 240 and the second flange 241 each form the second sealing surface 211.

In this way, the second seal surface 211 is formed by adding the first bead 240 and the second bead 241 to the left rocker inner panel 102 and the right rocker inner panel 103 of the vehicle 1000, and no additional component is required, so that the manufacturing cost can be reduced. In addition, the left rocker inner panel 102 and the right rocker inner panel 103 forming the second sealing surface 211 have high structural strength, which is beneficial to the stability of sealing.

Specifically, the first flange 240 and the second flange 241 may have the same shape or may have different shapes. The left and right rocker inner panels 102 and 103 may be connected with the left and right rocker beams 400 and 500, respectively, through an FDS process (Flow DRI LL SCREW, flow drilling screw process), thereby improving the rigidity of the connection and thus improving the sealing stability of the second sealing surface 211.

Referring to fig. 3, in some embodiments, the second seal beam 24 is coupled to a seat rail 300 of the vehicle 1000. In this manner, the seat cross member 300 of the vehicle 1000 can provide support for the second seal beam 24, thereby improving the structural strength of the second seal beam 24 and further improving the sealing stability of the second seal beam 24.

Specifically, the second sealing beam 24 may be connected to the seat cross beam 300 of the vehicle 1000 by welding, screwing, or the like. 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 connection of the second sealing beam 24 and the seat cross beam 300 may be achieved by welding points and solder.

Referring to fig. 4 and 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, and the third sealing surface 212 connects with the second sealing surface 211.

In this way, the third sealing surface 212 connects the second sealing surfaces 211, which can form a continuous sealing structure, thereby improving the sealing performance of the first sealing beam 22, the two second sealing beams 24, and the third sealing beam 25 as a whole.

Specifically, the surface of the third sealing beam 25 facing the same as the second sealing surface 211 may be formed with a third sealing surface 212. The third sealing surface 212 and the second sealing surface 211 may contact each other, and mutually adjacent regions of the third sealing surface 212 and the second sealing surface 211 may be coplanar, thereby improving the continuity of the seal.

Referring to fig. 4, in some embodiments, the third seal beam 25 is coupled to a rear floor front cross member 600 of the vehicle 1000. In this manner, the rear floor front cross member 600 of the vehicle 1000 can provide support for the third seal beam 25, thereby improving the structural strength of the third seal beam 25 and thus improving the sealing stability of the third seal beam 25.

Specifically, the third seal beam 25 may be disposed below the rear floor front cross member 600 of the vehicle 1000 in the Z-direction of the vehicle 1000. The third sealing beam 25 may be connected to the rear floor front cross member 600 of the vehicle 1000 by welding, screwing, or the like. For example, a plurality of corresponding welding points may be provided on the third sealing beam 25 and the rear floor front cross member 600, and the connection of the third sealing beam 25 and the rear floor front cross member 600 may be achieved through the welding points and the solder.

Referring to fig. 4, in some embodiments, the first, second, and third sealing surfaces 210, 211, 212 are joined end-to-end and collectively define a sealing surface 21, the sealing surface 21 being joined with a seat rail 300 of the vehicle 1000.

In this way, the sealing surface 21 is formed by connecting the first sealing surface 210, the second sealing surface 211 and the third sealing surface 212 end to end, and the first sealing beam 22, the second sealing beam 24 and the third sealing beam 25 which are correspondingly connected end to end, so that the split structure has higher material utilization rate and lower manufacturing cost. The sealing surface 21 is connected with the seat cross beam 300, so that the sealing surface 21 and the seat cross beam 300, the central channel 10 and other structures form a frame structure, and the dimensional stability is good.

In addition, the first sealing surface 210, the second sealing surface 211 and the third sealing surface 212 are all arranged on the front floor assembly 100, and the size chain is short, so that the flatness of the sealing surface 21 can be effectively ensured.

Specifically, the first sealing surface 210, the second sealing surface 211, and the third sealing surface 212 may enclose a rectangular-like sealing surface 21, and two ends of the seat cross member 300 may connect two opposite sides of the rectangular-like shape.
