[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0032] Reference will be made below to Figure 1 and Figure 2 to describe the vehicle body assembly 100 according to an embodiment of the present utility model.

[0033] As Figure 1 and Figure 2 shown, the vehicle body assembly 100 according to an embodiment of the present utility model includes: a threshold beam 10, a front bulkhead 40, and a floor 20.

[0034] Among them, the threshold beam 10 includes an inner threshold panel 11. The inner threshold panel 11 includes a first plate body 111 and a second plate body 112. The first plate body 111 and the second plate body 112 are connected. As some embodiments of the present application, the first plate body 111 and the second plate body 112 can be connected by, but not limited to, welding, bolt connection, etc. As some embodiments of the present application, the first plate body 111 and the second plate body 112 can be integrally formed parts. The first plate body 111 extends along the height direction of the vehicle body assembly 100 (i.e., Figure 1 the Z direction shown), and the second plate body 112 extends along the width direction of the vehicle body assembly 100 (i.e., Figure 1extends in the Y direction as shown, and the second plate body 112 is provided at one end of the first plate body 111 away from the ground, that is, along the height direction of the vehicle body assembly 100 (i.e., Figure 1 in the Z direction as shown), the second plate body 112 is provided at the upper end of the first plate body 111.

[0035] Among them, the height direction of the vehicle body assembly 100 (i.e., Figure 1 in the Z direction as shown) is perpendicular to the width direction of the vehicle body assembly 100 (i.e., Figure 1 in the Y direction as shown).

[0036] As some embodiments of the present application, in the height direction of the vehicle body assembly 100 (i.e., Figure 1 in the Z direction as shown), the first plate body 111 has opposite ends, and one end of the first plate body 111 close to the second plate body 112 is connected to the end of the second plate body 112.

[0037] The front bulkhead 40 is connected to the second plate body 112, and the floor 20 is connected to the second plate body 112. As some embodiments of the present application, the floor 20 may include a front floor 21 and a rear floor 22, and both the front floor 21 and the rear floor 22 are connected to the second plate body 112.

[0038] As some embodiments of the present application, along the length direction of the vehicle body assembly 100, the front bulkhead 40, the front floor 21, and the rear floor 22 are arranged in sequence.

[0039] As some embodiments of the present application, the front floor 21 includes a connected front floor body 211 and a front floor flange 212, and the front floor flange 212 is connected to the second plate body 112. As some embodiments of the present application, the rear floor 22 includes a connected rear floor body 221 and a rear floor flange 222, and the rear floor flange 222 is connected to the second plate body 112. As some embodiments of the present application, the front bulkhead 40 includes a connected front bulkhead body 41 and a front bulkhead flange 42, and the front bulkhead flange 42 is connected to the second plate body 112.

[0040] As some embodiments of the present application, the front bulkhead 40, the front floor 21, and the rear floor 22 are all connected to the second plate body 112 by welding.

[0041] It should be noted that in the prior art, in order to ensure that the power battery pack has a certain ground clearance, it is necessary to make the front bulkhead of the vehicle and the floor of the vehicle have a certain ground clearance, and the front bulkhead of the vehicle and the floor of the vehicle are both connected to the vertical surface of the sill beam, resulting in a relatively high height of the sill beam of the vehicle. A relatively high height of the sill beam will cause difficulties for users to enter and exit the passenger compartment, seriously affecting the user's driving experience.

[0042] In the present application, the second plate body 112 extends along the width direction of the vehicle body assembly 100 (i.e., Figure 1 the Y direction shown), and, along the height direction of the vehicle body assembly 100 (i.e., Figure 1 the Z direction shown), the second plate body 112 is provided at the upper end of the first plate body 111. By connecting the front bulkhead 40 and the floor 20 to the second plate body 112, the height of the sill beam 10 can be reduced. After the height of the sill beam 10 is reduced, the distance between the uppermost end of the sill beam 10 and the ground will decrease, thereby facilitating the user to enter and exit the passenger compartment. For example, it can facilitate the elderly with inconvenient legs and feet and children with relatively low height to enter and exit the passenger compartment, and can also reduce the probability that the sill beam 10 trips the user during the process of entering the passenger compartment, which is beneficial to improving the user's vehicle use experience.

[0043] Therefore, by connecting the front bulkhead 40 and the floor 20 to the second plate body 112 that extends along the width direction of the vehicle body assembly 100, on the basis of ensuring that the front bulkhead 40 and the floor 20 both have a certain ground clearance, the height of the sill beam 10 can be reduced, thereby reducing the difficulty for the user to enter and exit the passenger compartment and improving the user's vehicle use experience.

[0044] As a specific embodiment, after measurement, compared with the prior art, the distance between the uppermost end of the sill beam 10 of the vehicle body assembly 100 proposed in the present application and the ground can be reduced by about 25 mm.

[0045] In some embodiments of the present utility model, as Figure 1 shown, the sill beam 10 further includes: a sill outer panel 12, the sill outer panel 12 is connected to the sill inner panel 11, and the sill outer panel 12 and the sill inner panel 11 jointly define a cavity structure 13. The sill outer panel 12 includes a third plate body 121, and the third plate body 121 extends along the height direction of the vehicle body assembly 100 (i.e., Figure 1 the Z direction shown), and the third plate body 121 is disposed opposite to and spaced apart from the first plate body 111. As some embodiments of the present application, along the width direction of the vehicle body assembly 100 (i.e., Figure 1 the Y direction shown), the third plate body 121 is disposed opposite to and spaced apart from the first plate body 111.

[0046] Such a setting can enable the sill outer panel 12 and the sill inner panel 11 to jointly define a cavity structure 13, thereby improving the side impact performance of the sill beam 10, being beneficial to reducing the intrusion amount of the sill beam 10 during a side impact, and being beneficial to improving the safety performance of the vehicle body assembly 100.

[0047] In some embodiments of the present utility model, as Figure 1As shown, the distance between the third plate body 121 and the first plate body 111 is A, and A can satisfy the relationship: 112mm ≤ A ≤ 132mm, that is, the distance between the third plate body 121 and the first plate body 111 can be any value between 112mm and 132mm. For example, the distance between the third plate body 121 and the first plate body 111 can be, but not limited to, 122mm, 132mm, etc. Such a setting can make the distance between the third plate body 121 and the first plate body 111 reasonable, and can increase the size of the cavity structure 13 in the width direction of the vehicle body assembly 100 (i.e., Figure 1 the Y direction shown), and can improve the bending and torsion resistance performance of the sill beam 10, so as to further improve the side collision performance of the sill beam 10, and can further improve the safety performance of the vehicle body assembly 100.

[0048] In some embodiments of the present invention, as Figure 2 shown, the vehicle body assembly 100 further includes: a front sill 50, and the front sill 50 is connected to the sill beam 10. As some embodiments of the present application, along the length direction of the vehicle body assembly 100 (i.e., Figure 1 the X direction shown), the sill beam 10 extends, and the front sill 50 is arranged at the front end of the sill beam 10 and is connected to the sill beam 10. As some embodiments of the present application, the front sill 50 is welded to the sill beam 10. The front sill 50 has a fifth plate body 51, and along the width direction of the vehicle body assembly 100 (i.e., Figure 1 the Y direction shown), the fifth plate body 51 extends, and the fifth plate body 51 is connected to the second plate body 112, and the front bulkhead 40 is connected to the fifth plate body 51.

[0049] As some embodiments of the present application, the front bulkhead 40 includes a connected front bulkhead body 41 and a front bulkhead flange 42, and the front bulkhead flange 42 is welded to both the second plate body 112 and the fifth plate body 51.

[0050] Such a setting can make the connection area between the front bulkhead 40 and the sill beam 10 and the front sill 50 flat, and can make the connection area between the front bulkhead 40 and the sill beam 10 and the front sill 50 transition smoothly, avoiding the appearance of a sharp transition area, so as to avoid the occurrence of gaps (mouse holes) at the connection between the front bulkhead 40 and the front sill 50, which is beneficial to improving the airtightness and water tightness of the vehicle body assembly 100, and is also beneficial to improving the NVH performance (Noise, Vibration, Harshness) of the vehicle body assembly 100.

[0051] In some embodiments of the present invention, as Figure 2As shown, the vehicle body assembly 100 further includes: a rear sill section 60, the rear sill section 60 being connected to the sill beam 10. As some embodiments of the present application, along the length direction of the vehicle body assembly 100, the sill beam 10 extends, and the rear sill section 60 is disposed at the rear end of the sill beam 10 and is connected to the sill beam 10. As some embodiments of the present application, the rear sill section 60 is welded to the sill beam 10.

[0053] Such a setting can make the connection area between the floor 20 and the sill beam 10 and the rear sill section 60 flat, and can make the connection area between the floor 20 and the sill beam 10 and the rear sill section 60 have a smooth transition, avoiding the occurrence of a sharp transition area, thereby avoiding the appearance of gaps (mouse holes) at the connection between the floor 20 and the rear sill section 60. Thus, it is beneficial to improve the airtightness and water tightness of the vehicle body assembly 100, and is also beneficial to improving the NVH performance (Noise, Vibration, Harshness) of the vehicle body assembly 100.

[0054] As some embodiments of the present application, as Figure 2 shown, the front sill section 50, the sill beam 10, and the rear sill section 60 all extend along the length direction of the vehicle body assembly 100, and the front sill section 50, the sill beam 10, and the rear sill section 60 are sequentially connected along the length direction of the vehicle body assembly 100.

[0055] As some embodiments of the present application, as Figure 2 shown, the fifth plate body 51 of the front sill section 50, the second plate body 112 of the sill beam 10, and the sixth plate body 61 of the rear sill section 60 all extend along the width direction of the vehicle body assembly 100 (i.e., Figure 1 the Y direction shown), and along the length direction of the vehicle body assembly 100, the fifth plate body 51 of the front sill section 50, the second plate body 112 of the sill beam 10, and the sixth plate body 61 of the rear sill section 60 are sequentially connected.

[0056] In some embodiments of the present invention, as Figure 2As shown, the floor 20 includes a front floor 21 and a rear floor 22. Among them, the front bulkhead 40, the front floor 21, and the rear floor 22 are all connected to the second plate body 112.

[0057] In some embodiments of the present application, the front floor 21 includes a connected front floor body 211 and a front floor flange 212, and the front floor flange 212 is connected to the second plate body 112. In some embodiments of the present application, the rear floor 22 includes a connected rear floor body 221 and a rear floor flange 222, and the rear floor flange 222 is connected to the second plate body 112. In some embodiments of the present application, the front bulkhead 40 includes a connected front bulkhead body 41 and a front bulkhead flange 42, and the front bulkhead flange 42 is connected to the second plate body 112.

[0058] In some embodiments of the present application, the front bulkhead flange 42, the front floor flange 212, and the rear floor flange 222 are all connected to the second plate body 112 by welding, and the front floor flange 212 is connected between the front bulkhead flange 42 and the rear floor flange 222. Such a setting can make the structural form of the vehicle body assembly 100 reasonable and can reduce the height of the sill beam 10 to facilitate the user to enter and exit the passenger compartment.

[0059] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the front floor 21 includes a front floor body 211 and a front floor flange 212, and the front floor body 211 and the front floor flange 212 are connected. In some embodiments of the present application, the front floor body 211 and the front floor flange 212 are integrally formed parts. The front floor flange 212 is connected to the second plate body 112. In some embodiments of the present application, the front floor flange 212 is connected to the second plate body 112 by welding. Such a setting can facilitate the connection of the front floor 21 to the sill beam 10, which is beneficial to reducing the assembly difficulty of the vehicle body assembly 100 and improving the assembly efficiency of the vehicle body assembly 100.

[0060] In some embodiments of the present invention, as Figure 2 shown, the vehicle body assembly 100 further includes: a front seat mounting cross beam 70 and a connecting member 80. The connecting member 80 is connected between the front seat mounting cross beam 70 and the sill beam 10.

[0061] In some embodiments of the present application, the front seat mounting cross beam 70 includes a front seat front mounting cross beam and a front seat rear mounting cross beam. Both the front seat front mounting cross beam and the front seat rear mounting cross beam are along the width direction of the vehicle body assembly 100 (i.e., Figure 1It extends in the Y direction (as shown), and the front seat front mounting cross member and the front seat rear mounting cross member are spaced apart in the longitudinal direction of the vehicle body assembly 100.

[0062] The number of the connecting members 80 can be four. Two connecting members 80 are respectively connected to both ends of the front seat front mounting cross member, and two connecting members 80 are respectively connected to both ends of the front seat rear mounting cross member. All four connecting members 80 have connecting flanges 81, and the connecting flanges 81 are connected to the corresponding front floor flanges 212.

[0063] It should be noted that in the prior art, in order to ensure that the power battery pack has a certain ground clearance, it is necessary to make the front apron and the floor of the vehicle have a certain ground clearance. However, the front apron and the floor of the vehicle are both connected to the vertical surface of the sill beam.

[0066] Such a setting can make the positions of the second plate body 112, the front floor flange 212, and the connecting flange 81 reasonable, can improve the overall structural strength of the second plate body 112, the front floor flange 212, and the connecting flange 81, is conducive to improving the side impact performance of the vehicle body assembly 100, and is conducive to improving the safety performance of the vehicle.

[0067] As some embodiments of the present application, as Figure 1 shown, the power battery pack 30 of the vehicle can be arranged on the floor 20 by means of bolt connection.

[0068] A vehicle according to an embodiment of the present utility model includes the body assembly 100 of the vehicle in the above embodiment. By connecting the front bulkhead 40 and the floor 20 to the second plate body 112 extending in the width direction of the body assembly 100, the height of the sill beam 10 can be reduced on the basis of ensuring that both the front bulkhead 40 and the floor 20 have a certain ground clearance, thereby reducing the difficulty for users to enter and exit the passenger compartment and improving the user's vehicle use experience.
