A vehicle body assembly 100 according to an embodiment of the invention is described below with reference to fig. 1-11.
As shown in fig. 1 to 11, a vehicle body assembly 100 according to an embodiment of the present invention includes: threshold boundary beam planking 5, threshold boundary beam inner panel 6 and threshold roof beam strengthen subassembly 1.
As shown in fig. 1, the rocker outer panel 5 is mounted to the side of the vehicle body, and as shown in fig. 1 to 3, the rocker inner panel 6 is connected to the vehicle body floor, and the rocker reinforcement assembly 1 is disposed between the rocker outer panel 5 and the rocker inner panel 6. It should be noted that the rocker side sill outer panel 5 is connected with the vehicle body B pillar, so that, when a vehicle is in side impact, the impact force received by the vehicle body side wall and the vehicle body B pillar is transmitted to the rocker reinforcement assembly 1 through the rocker side sill outer panel 5, part of the impact energy is absorbed by the rocker reinforcement assembly 1, and part of the impact energy is transmitted to the vehicle body floor through the rocker reinforcement assembly 1 and is absorbed by the vehicle body floor and other components mounted on the vehicle body floor, such as a longitudinal beam 3 mounted on the outer side of a front seat mounted on the vehicle body floor, a front seat cross beam 4 and the like, thereby avoiding the damage of the vehicle interior caused by external impact, and improving the safety of the vehicle occupant.
The direction of outer finger keeping away from car central line, the direction that the interior finger is close to the car central line that this application said. The longitudinal direction, i.e., the X direction, refers to the front-rear direction of the vehicle; the lateral direction is the Y direction and refers to the left and right directions of the vehicle; the vertical direction, i.e., the Z direction, refers to the up-down direction of the vehicle.
As shown in fig. 4-5, the rocker reinforcement assembly 1 includes a rocker reinforcement 11, a rocker side reinforcement bracket 12 and a position-limiting structure 13, the rocker reinforcement 11 is connected to the rocker side outer panel 5 by welding, the rocker reinforcement 11 is connected to the rocker side inner panel 6 by the rocker side reinforcement bracket 12, that is, the rocker reinforcement 11 is connected to the rocker side reinforcement bracket 12, wherein, as shown in fig. 4, the rocker reinforcement 11 is connected to the rocker side reinforcement bracket 12 by a screw fastener.

The rocker side sill reinforcing bracket 12 has a crush structure which deforms and collapses when the side of the vehicle body is impacted, so as to absorb impact energy during deformation, thereby reducing the impact energy transmitted to the rocker side sill inner panel 6.
The limit structure 13 is connected with the threshold reinforcing beam 11, the limit structure 13 can be connected with the threshold reinforcing beam 11 in a welding mode, or the limit structure 13 can be connected with the threshold reinforcing beam 11 through a threaded fastener, so that the limit structure 13 is relatively fixed with the threshold reinforcing beam 11, and the limit structure 13 is abutted against the threshold boundary beam reinforcing bracket 12 when the threshold boundary beam reinforcing bracket 12 reaches a preset collapse amount, namely the limit structure 13 limits the threshold boundary beam reinforcing bracket 12 to further collapse when the collapse structure reaches the preset collapse amount. Therefore, the doorsill edge beam reinforcing bracket 12 can play a certain energy absorption role in the early stage of collision, and the limiting structure 13 abuts against the doorsill edge beam reinforcing bracket 12 after absorbing part of energy so as to prevent the doorsill edge beam reinforcing bracket 12 from excessively deforming, and the self strength and the anti-crushing capability of the doorsill edge beam reinforcing bracket 12 are improved.

According to the vehicle body assembly 100 provided by the embodiment of the invention, the threshold beam reinforcing component 1 consisting of the threshold reinforcing beam 11, the threshold boundary beam reinforcing bracket 12 and the limiting structure 13 is arranged between the threshold boundary beam inner plate 6 and the threshold boundary beam outer plate 5, so that the vehicle body assembly 100 has a good collapse effect in the early stage of collision, and after the threshold boundary beam reinforcing bracket 12 absorbs part of collision energy, the threshold beam reinforcing component 1 has high structural strength and anti-collapse capability, further effectively transmits the collision energy to other areas of the vehicle body assembly 100, ensures that the deformation amount of the threshold along the Y direction is not too large, further effectively reduces the B column crush intrusion amount, reduces the intrusion speed, and ensures the living space and safety of passengers.
In some embodiments, the rocker reinforcement bracket 12 has a guide channel 126, the guide channel 126 extends in a transverse direction, a first end of the restraint structure 13 is connected to the rocker reinforcement beam, a second end of the restraint structure 13 extends into the guide channel 126, and the second end of the restraint structure 13 is spaced from an inner end of the guide channel 126 in the transverse direction when the crush structure is not collapsed, and the second end of the restraint structure 13 presses against the inner end of the guide channel 126 in the transverse direction when the crush structure reaches a predetermined amount of collapse to prevent over-collapse of the rocker reinforcement bracket 12.
A part of the limit structure 13 extends into the guide groove 126 and the limit structure 13 can move along the extending direction of the guide groove 126 when the vehicle body is laterally collided. As shown in fig. 5, the restraining structure 13 is attached to the rocker reinforcement beam 11, and a portion of the restraining structure 13 is located near the outer end of the guide groove 126 in the lateral direction when the vehicle body is not subjected to lateral force or is subjected to extremely small lateral force. When the automobile body receives the horizontal power effect, threshold boundary beam reinforcing bracket 12 takes place the collapse along transversely to be out of shape, and threshold reinforcing beam 11 and limit structure 13 move towards the inboard, and when limit structure 13 partly supported and pressed to guide way 126 along horizontal inner, threshold boundary beam reinforcing bracket 12 no longer warp, and threshold boundary beam reinforcing bracket 12 transmits the impact through threshold boundary beam inner panel 6 for other positions of automobile body assembly 100, from this, can guarantee threshold roof beam and strengthen the structural strength and the compressive capacity of subassembly 1.
