They are, of course, merely examples and are not intended to limit the utility model. Furthermore, the present utility model may repeat reference numerals and/or letters in the various examples.

In the present embodiment, the "left-right direction" is the width direction of the vehicle, the "up-down direction" is the height direction of the vehicle, and the "front-back direction" is the longitudinal direction of the vehicle.

A front wall panel assembly 100 according to an embodiment of the present utility model is described below with reference to fig. 1-3.

As shown in fig. 1-2, a front wall panel assembly 100 according to an embodiment of the present utility model includes: the first cross member 11, the second cross member 12, the sub-frame rear mounting plate 26, and the engine rear mounting plate 27.

The first cross beam 11 is connected with the front floor middle channel 21, the second cross beam 12 and the first cross beam 11 are spaced apart along the front-rear direction and are staggered along the up-down direction, the left and right ends of the second cross beam 12 are respectively connected with the left threshold beam 22 and the right threshold beam 23, and the upper and lower sides of the front floor left reinforcing longitudinal beam 24 and the upper and lower sides of the front floor right reinforcing longitudinal beam 25 are respectively connected with the first cross beam 11 and the second cross beam 12; the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 are both mounted to the second cross member 12, and the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 are connected by the reinforcement beam 13.

Therefore, the front wall plate assembly 100 can form a plurality of force transmission paths, so that when the vehicle 1000 is subjected to a frontal collision, collision energy can be dispersed through the plurality of force transmission paths, and the front wall plate assembly 100 is prevented from being excessively deformed by the collision energy of the front floor middle channel 21, namely the collision energy of the front floor middle channel 21, and meanwhile, the reinforcing beam 13 connects the auxiliary frame rear mounting plate 26 and the engine rear mounting plate 27 into a whole, so that the structural strength of the front wall plate assembly 100 is conveniently reinforced, and the deformation generated by forces transmitted from two sides can be effectively counteracted.

For example, the first cross member 11 and the second cross member 12 each extend in the left-right direction, and the first cross member 11 and the second cross member 12 are spaced apart in the front-rear direction and are disposed in a staggered manner in the up-down direction, that is, the first cross member 11 and the second cross member 12 are not at the same horizontal level, so that the front floor left reinforcing longitudinal member 24 and the front floor right reinforcing longitudinal member 25 can be disposed between the first cross member 11 and the second cross member 12 in a penetrating manner in the front-rear direction, and at the time of actual assembly, the up-down sides of the front floor left reinforcing longitudinal member 24 and the up-down sides of the front floor right reinforcing longitudinal member 25 are connected to the first cross member 11 and the second cross member 12, respectively.

Further, the first cross member 11 is connected to the front floor center tunnel 21, and the front floor center tunnel 21 is connected to the seat cross member, and both left and right ends of the second cross member 12 are connected to the left and right rocker beams 22 and 23, respectively, and the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 are both mounted to the second cross member 12, and the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 are spaced apart in the left-right direction and are connected to each other by the reinforcement beam 13.

When the vehicle 1000 is subjected to a frontal collision, the front floor left reinforcement beam 13 and the front floor right reinforcement beam 13 are subjected to a collision first, then, collision energy is transmitted along the front floor left reinforcement beam 13 and the front floor right reinforcement beam 13 toward the passenger compartment of the vehicle 1000, the collision energy is dispersed by the first cross beam 11 and the second cross beam 12 when the collision energy is transmitted to the front dash panel assembly 100, a part of the collision energy is transmitted to the left and right rocker beams 22 and 23 along the second cross beam 12 and absorbed by the cavities of the left and right rocker beams 22 and 23, a part of the collision energy is transmitted to the seat cross beam along the first cross beam 11 and the front floor center tunnel 21, and a part of the collision energy is transmitted to the sub-frame rear mounting plate 26 along the second cross beam 12 and a part of the collision energy is transmitted to the engine rear mounting plate 27 along the second cross beam 12.

In the present utility model, the crash energy can be transmitted through the above at least four force transmission paths, so that the overall stress of the vehicle body is more uniform, and the passenger compartment can be better protected, in particular, the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 are connected together through the reinforcing beam 13, so that the structural strength of the front wall plate assembly 100 is conveniently reinforced, and the deformation generated by the forces transmitted from two sides can be effectively counteracted, i.e. the front wall plate assembly 100 can better resist the deformation, and the passenger compartment of the vehicle 1000 can be protected.

According to the front wall plate assembly 100 of the embodiment of the utility model, the reinforcement beam 13 is arranged, so that the transmission path of collision energy can be increased, and the auxiliary frame rear mounting plate 26 and the engine rear mounting plate 27 can be connected together through the reinforcement beam 13, so that the structural strength of the front wall plate assembly 100 is conveniently reinforced, the deformation generated by forces transmitted from two sides can be effectively counteracted, namely, the front wall plate assembly 100 can resist deformation better, the collision safety performance of the front wall plate assembly 100 is improved, and the passenger cabin of the vehicle 1000 is further protected.

In some embodiments, as shown in fig. 1-2, the illustrated second cross member 12 includes left and right cross members 121, 122 spaced apart in the left-right direction, the left and right cross members 121, 122 are connected to the left and right rocker beams 22, 23, respectively, and the subframe rear mounting plate 26 and the engine rear mounting plate 27 are in abutting connection with the left and right cross members 121, 122, respectively.

Thus, after the front wall panel assembly 100 is subjected to a frontal collision, the left and right cross members 121 and 122 can transfer part of the collision energy to the left and right side sill beams 22 and 23, and the left and right side sill beams 22 and 23 have cavities therein, so that the left and right side sill beams 22 and 23 can absorb the collision energy as much as possible, and the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 are respectively attached to the left and right cross members 121 and 122, so as to increase the contact area of the sub-frame rear mounting plate 26 and the left cross member 121 and the contact area of the engine rear mounting plate 27 and the right cross member 122, thereby increasing the structural stability of the sub-frame rear mounting plate 26 and the engine rear mounting plate 27.

In some embodiments, as shown in fig. 1, the end of the left cross member 121 remote from the left rocker 22 is sandwiched between the reinforcement beam 13 and the subframe mounting plate, and the end of the right cross member 122 remote from the right rocker 23 is sandwiched between the reinforcement beam 13 and the engine rear mounting plate 27.

Thus, the left cross member 121 and the right cross member 122 are connected together by the reinforcement beam 13, so that the second cross member 12 is integrally connected in the width direction of the vehicle 1000, and the second cross member 12 can also be a force transmission path when the front wall plate assembly 100 is subjected to a frontal collision, so that the force transmission effect of the front wall plate assembly 100 is better.

It should be noted that, in the C-NCAP crash test, MPDB is an important condition for a crash, which requires scoring according to the deformation degree of the vehicle 1000 after the vehicle 1000 is front-offset by 50% of the crash, whereas in the related art, the second cross members 12 of the front wall plate assembly 100 are not connected together, only the first cross members 11 are integrally formed in the left-right direction, and the score is low after the front crash is suffered, so that the front wall plate of the vehicle 1000 needs to be reinforced to be able to score in order to achieve the five-star crash.

Thus, the front wall panel assembly 100 of the present utility model disperses and transmits the collision energy and enables the front wall panel assembly 100 to be deformed to a smaller extent, avoiding intrusion into the passenger compartment of the vehicle 1000.

In some embodiments, as shown in fig. 1, at least part of the reinforcement beam 13 is provided protruding upward in the up-down direction.

For example, the middle portion of the reinforcement beam 13 is provided to protrude upward, so that the occupation of the space below by the reinforcement beam 13 can be reduced, the ground clearance of the vehicle 1000 can be increased, and the trafficability of the vehicle 1000 can be increased.

In some embodiments, as shown in fig. 1, the reinforcement beam 13 includes a middle connecting section 131 and two end connecting sections 132, the middle connecting section 131 is connected between the two end connecting sections 132, and one ends of the two end connecting sections 132 facing away from the middle connecting section 131 are respectively connected with the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 in a bending manner.

Specifically, the two end connection sections 132 are respectively connected with the sub-frame rear mounting plate 26 and the engine rear mounting plate 27 in a bending manner, and the two end connection sections 132 are connected together through the middle connection section 131, so that at least part of the reinforcing beam 13 is convenient to protrude upwards along the up-down direction to reduce the occupation of the reinforcing beam 13 to the space below, and meanwhile, the extension length of the reinforcing beam 13 can be increased, so that the transmission path of collision energy is prolonged, and the consumption of collision energy is convenient.

In some embodiments, as shown in fig. 1, the front wall panel assembly 100 further includes a first structural reinforcement 28, the first structural reinforcement 28 being connected between the subframe rear mounting plate 26 and the left rocker beam 22.

Thus, the first structural reinforcement 28 is coupled between the subframe rear mounting plate 26 and the left rocker beam 22, and the first structural reinforcement 28 provides a force transfer path for the front wall panel assembly 100 when the vehicle 1000 is subject to a frontal collision, thereby allowing some of the crash energy to be transferred to the left rocker beam 22 via the first structural reinforcement 28, and thus allowing the left rocker beam 22 to better absorb the crash energy in the front wall panel assembly 100.

In some embodiments, as shown in FIG. 1, the first structural reinforcement 28 is bent over to connect with the subframe rear mounting plate 26.

Accordingly, the first structural reinforcement 28 may have a certain gap with the left cross member 121 after bending, so that the first structural reinforcement 28, the left cross member 121 and the left threshold beam 22 together define a cavity that is capable of absorbing a portion of the collision energy when the vehicle 1000 is subjected to a frontal collision, thereby reducing the collision energy transferred into the passenger compartment of the vehicle 1000, and thus effectively protecting the passenger compartment of the vehicle 1000.

In some embodiments, as shown in fig. 1, the front wall panel assembly 100 further includes a second structural reinforcement 29, the second structural reinforcement 29 being connected between the engine rear mounting plate 27 and the right rocker beam 23.

Thus, the second structural reinforcement 29 is connected between the engine rear mounting plate 27 and the right rocker beam 23, and the second structural reinforcement 29 provides a force transmission path for the front wall panel assembly 100 when the vehicle 1000 is subject to a frontal collision, thereby allowing some of the crash energy to be transferred to the right rocker beam 23 via the second structural reinforcement 29, and thus allowing the right rocker beam 23 to better absorb the crash energy in the front wall panel assembly 100.

In some embodiments, as shown in FIG. 1, the second structural reinforcement 29 is crimped to the engine rear mounting plate 27.

Thus, the second structural reinforcement 29 will have a certain clearance from the right cross member 122 after bending, so that the second structural reinforcement 29, together with the right cross member 122 and the right threshold beam 23, defines a cavity that is also capable of absorbing part of the crash energy, thereby reducing the crash energy transferred into the passenger compartment of the vehicle 1000, and further protecting the passenger compartment of the vehicle 1000.
