In this technical solution, since the front wheel house front reinforcement beam 4 is provided in front of the front wheel house 3 in the front-rear direction of the vehicle, the strength of the front portion of the front wheel house 3 is enhanced, and at the same time, one side of the front wheel house front reinforcement beam 4 is connected to the front side member 1, the other side of the front wheel house front reinforcement beam 4 opposite thereto is connected to the front roof side member 2, and a wheel house cavity 5 extending between the front side member 1 and the front roof side member 2 is formed between the front wheel house front reinforcement beam 4 and the front wheel house 3, so that, in the event of a collision such as a small offset collision, as shown by a broken line arrow in fig. 1, the collision force is transmitted rearward along the front side member 1, and since the front wheel house reinforcement beam 4 reinforces the strength of the front portion of the front wheel house 3, the front wheel house 3 is not easily deformed, and, at the same time, a part of the collision force will be transmitted to the front roof side member 2 along the front wheel house reinforcement beam 4 and then transmitted rearward along the front roof, due to the wheel house cavity 5, the deformation of the front wheel house 3 can be reduced, and the overall deformation of the vehicle body front compartment frame can be reduced, so that the vehicle body front compartment frame structure can well absorb collision energy during vehicle collision, such as small offset collision, and the safety performance can be improved.
In addition, the front wheel house front reinforcement beam 4 may be provided at any position of the front portion of the front wheel house 3 as long as the strength of the front portion of the front wheel house 3 can be reinforced. For example, in one configuration, the front wheel house front reinforcing beam 4 is provided at a front end surface of a front portion of the front wheel house 3 toward the front of the vehicle, for example, the front wheel house front reinforcing beam 4 is a U-shaped plate, and both side walls of the U-shaped plate are connected to both side surfaces of the front wheel house 3, respectively, so that the wheel house cavities 5 can be formed at both sides of the front wheel house 3, respectively.

Thus, as shown by the broken line arrows in fig. 1, the front side member inner panel 8 can increase the strength of the front side member 1 and reduce the possibility of deformation when the front side member 1 transmits a main collision force rearward. The supporting cross member 9 can transmit a part of the collision force of the front side frame 1 on one side to the front side frame 1 on the other side, or the supporting cross member 9 can simultaneously receive a part of the collision force transmitted by the front side frames 1 on both sides so that the collision forces can be offset.
In a second aspect, the present invention provides a vehicle body front compartment frame structure, as shown in fig. 1 and 2 and fig. 7 and 8, which includes a front side member 1 and an outer side enlarged support portion 10 that are connected, wherein the outer side enlarged support portion 10 is located outside a front end 11 of the front side member 1 in a vehicle width direction, and the outer side enlarged support portion 10 includes an enlarged portion cavity 12.
In this front-compartment frame structure for a vehicle body, since the outside expansion support portion 10 is located outside the front end 11 of the front side member 1 in the vehicle width direction, so that the impact beam comes into contact with the barrier at the time of a vehicle collision such as a small offset collision, the impact force can be transmitted to the front side member 1 through the outside expansion support portion 10, and the vehicle body can be slid out from the barrier side by the support action of the outside expansion support portion 10, avoiding the force of the continued collision, as indicated by the broken-line arrow in fig. 1, a part of the impact force will be transmitted to the front side member along the outside expansion support portion 10, and since the outside expansion support portion 10 includes the expansion cavity 12, the cavity wall of the expansion cavity 12 can be deformed accordingly, so that the outside expansion support portion 10 can also effectively absorb the collision energy while transmitting a part of the impact force. Therefore, the vehicle body front cabin frame structure can also well absorb collision energy during vehicle collision, such as small offset collision, and improve safety performance.
In this vehicle body front compartment frame structure, the outside enlarged support portion 10 may be formed in various ways, for example, in one way, as shown in fig. 7, the outside wall 13 of the front end 11 of the front side member 1 is projected to the outside to form the outside enlarged support portion 10, for example, a plate of the outside wall 13 is bent outward, for example, curved to form the outside enlarged support portion 10; alternatively, as shown in fig. 8, the front end 11 of the front side member 1 is provided with a front side member support plate 14 protruding outward, an enlarged cavity 12 is formed between the front side member support plate 14 and the outer side wall 13 of the front end 11 to form the outer enlarged support portion 10, for example, the outer side wall 13 of the front end 11 extends outward, the front side member support plate 14 may be connected between the outer side wall 13 and the front end plate 18 of the front side member 1, and the front side member support plate 14 may be a straight inclined plate or may be a curved inclined plate.
In addition, in order to improve the performance of the front side member 1 in transmitting collision force and reduce the deformation amount of the front side member 1, referring to fig. 2 and fig. 7 to 9, at the rear end 15 position of the outer enlarged support portion 10 toward the rear of the vehicle, a front side member inner support plate 8 corresponding to the rear end 15 position is provided in the front side member 1, and a support cross member 9 corresponding to the front side member inner support plate 8 position is provided between the two front side members 1 of the vehicle body front compartment frame structure. Of course, the structure of the front side member inner support plate 8 and the support cross member 9 is not limited to the specific structure shown in fig. 2 and 7, and besides, the front side member inner support plate 8 and the support cross member 9 may have other various structural forms, for example, the front side member inner support plate 8 may be an i-shaped, and the support cross member 9 may be a bent cross member or an X-shaped cross member. Thus, as shown by the broken line arrows in fig. 1, the collision force transmitted from the outer expansion support 10 acts on the front side member inner panel 8, and the front side member 1 is not easily deformed when transmitting the main collision force rearward from the front side member 1 because the front side member inner panel 8 increases the strength of the front side member 1. The supporting cross member 9 can transmit a part of the collision force of the front side frame 1 on one side to the front side frame 1 on the other side, or the supporting cross member 9 can simultaneously receive a part of the collision force transmitted by the front side frames 1 on both sides so that the collision forces can be offset.
Further, as shown in fig. 2, the vehicle body front compartment frame structure includes an energy absorbing structure 16 and an impact beam 17, wherein the energy absorbing structure 16 is provided between the front end 11 and the outside enlarged support portion 10 of the front side member 1 and the impact beam 17, wherein the width of the energy absorbing structure 16 in the vehicle width direction is the same as the width of the front end 11 and the outside enlarged support portion 10 in the vehicle width direction, and wherein the impact beam 17 extends outward beyond the energy absorbing structure 16 in the vehicle width direction. Thus, since the front end 11 of the front side member 1 and the outside enlarged support portion 10 are both provided with the energy absorbing structure, and the width of the energy absorbing structure 16 in the vehicle width direction, in which the impact beam 17 extends outward beyond the energy absorbing structure 16, is the same as the width of the front end 11 and the outside enlarged support portion 10 in the vehicle width direction, the effective absorption of the impact energy at the time of collision is improved. In this way, the impact beam 17 transmits the impact force to the energy absorbing structure 16, the energy absorbing structure 16 transmits the impact force to the front end 11 of the front side frame 1 and the outer expansion support 10, and the outer expansion support 10 transmits the impact force to the front side frame 1, and the impact energy is gradually absorbed during the transmission of the impact force.
In addition, the energy absorbing structure 16 may have various structural forms, and the energy absorbing structure 16 may be a energy absorbing box or may be a plurality of energy absorbing sheets which are arranged to be spaced apart from each other in the vehicle front-rear direction by a support.
Figure 5 shows that the energy absorbing structure 16 is a single energy absorbing box, in which a support plate 163 is arranged, for example, in the middle, in order to increase the strength of the single energy absorbing box, since the energy absorbing box has a larger width. Fig. 6 then shows that the energy absorbing structure 16 is a first energy absorption box 161 and a second energy absorption box 162, one of the first energy absorption box 161 and the second energy absorption box 162 may be arranged in front of the front end 11 of the front side member 1, and the other of the first energy absorption box 161 and the second energy absorption box 162 may be arranged in front of the outer enlarged support portion 10.
