In order to ensure the bearing capacity of the vehicle and provide a reliable installation basis for interior decorations, electrical appliances, chassis or power assemblies of the vehicle, the vehicle also comprises a vehicle body framework. The vehicle body frame is also critical for protecting occupants in the vehicle. Specifically, when a vehicle collides, collision force is generally dispersed through a body framework of the vehicle so as to achieve the purpose of buffering and absorbing energy.

In order to disperse the collision force, the transmission path of the collision force by the vehicle body frame is a factor that needs to be considered. However, the vehicle body frame in the related art is provided with a small number of transmission paths for the collision force, and cannot satisfactorily disperse the collision force.

In view of this, the present embodiments provide a vehicle body frame. Referring to fig. 1 and 2, the vehicle body frame includes a front wall panel assembly 1, a front side member 2, a front wheel cover assembly 3, and a front wall panel reinforcement member 4. Specifically, the front side member 2 is connected to a side of the front wall plate assembly 1 corresponding to the front portion of the vehicle; the front wheel cover assembly 3 is also connected to one side of the front wall plate assembly 1 corresponding to the front part of the vehicle; the front wall panel reinforcement member 4 includes a first reinforcement 41 and a second reinforcement 42, the first end of the first reinforcement 41 and the second end of the first reinforcement 41 being connected to the front wheel cover assembly 3 and the front wall panel assembly 1, respectively, and the first end of the second reinforcement 42 and the second end of the second reinforcement 42 being connected to the front side rail 2 and the front wall panel assembly 1, respectively.

The front wall panel assembly 1 may be regarded as a junction between the cabin and the front cabin of the vehicle, and the main structure of the front wall panel assembly 1 may be referred to as a front wall panel 11. Meanwhile, some reinforcing structures or mounting structures for mounting other components, etc., may be provided on the front wall panel 11, such as a front wall panel upper reinforcing beam, a front wall panel lower reinforcing beam 12, a front windshield fixing structure 13, an instrument desk fixing structure 14, etc.

In addition, the vehicle body frame provided in the embodiment of the present application further includes a front side member 2, and the front side member 2 is provided on a side of the front wall panel 11 corresponding to the front portion of the vehicle. The front side member 2 in the embodiment of the present application can be understood from the front side member 2 in a general vehicle body frame. The front side member 2 is a side member structure provided in the front portion of a vehicle body frame, and has a generally channel-shaped or i-shaped cross section, and the front side member 2 is a main energy absorption region and a transmission path of collision force when a vehicle collides. An impact beam 5 is generally provided at the front end of the front side member 2, and an energy absorber 51 is provided between the impact beam 5 and the front side member 2. The rear end of the front side member 2 is connected to the front panel assembly 1 such that the collision force can be dispersed to the roof of the vehicle body or the floor of the vehicle body by the front panel assembly 1.

Meanwhile, in the embodiment of the present application, the vehicle body frame further includes a front wheel cover assembly 3, and the front wheel cover assembly 3 is also attached to the front wall plate assembly 1 on the side corresponding to the front portion of the vehicle. According to the structural subdivision of the front wheel cover assembly 3, the front wheel cover assembly 3 generally comprises an inner baffle, a supporting plate, a mud guard, a connecting plate, an auxiliary bracket and other structures, and can support a front fender, a front hatch cover assembly, a front headlight and the like. In general, the front wheel cover assembly 3 is generally disposed above the front side member 2, and different portions of the front wheel cover assembly 3 are also generally connected to the front side member 2 and the front wall panel assembly 1, so that collision force can be transmitted and energy absorption can be buffered.

In the event of a collision of a vehicle, the structural members near the front of the corresponding front side members 2 are generally configured to have crush deformation capability in order to ensure safety of pedestrians or vehicles; meanwhile, in order to protect the safety of the driver and passengers in the cockpit of the vehicle, the structural members near the front wall plate assembly 1 are generally required to have certain strength and rigidity, so that the cockpit of the vehicle can be prevented from being greatly deformed.

For this, the vehicle body frame provided in the embodiment of the present application further includes the front wall panel reinforcement assembly 4. The front wall panel reinforcement member 4 serves to reinforce the front wall panel assembly 1 and, at the same time, also serves to disperse and transmit the collision force.

Specifically, referring to fig. 1 and 2, the front wall panel reinforcement member 4 in the embodiment of the present application includes a first reinforcement 41 and a second reinforcement 42, wherein a first end of the first reinforcement 41 and a second end of the first reinforcement 41 are connected to the front wheel cover assembly 3 and the front wall panel assembly 1, respectively, and a first end of the second reinforcement 42 and a second end of the second reinforcement 42 are connected to the front side rail 2 and the front wall panel assembly 1, respectively.

In the embodiment of the present application, the specific structural forms of the first reinforcing member 41 and the second reinforcing member 42 are not limited, and the first reinforcing member 41 and the second reinforcing member 42 may be made into various types of structures such as a rod-like structure, a plate-like structure, or a frame-like structure. For example, the first reinforcing member 41 may be provided in a rod-like structure, and the second reinforcing member 42 may be provided in a plate-like structure. Of course, the first reinforcement 41 may be provided in a plate-like structure, the second reinforcement 42 may be provided in a rod-like structure, or the like.

In addition, in the embodiment of the present application, the positions where the first end of the first reinforcement 41 is connected to the front wheel cover assembly 3 and the positions where the second end of the first reinforcement 41 is connected to the front wall plate assembly 1 are defined. Illustratively, the first end of the first reinforcement 41 may be connected to a position of the front wheel cover assembly 3 that is relatively forward, and the first end of the first reinforcement 41 may be connected to a position of the front wheel cover assembly 3 that is relatively rearward. In addition, the second end of the first reinforcement 41 may be connected to the front wall panel assembly 1 at a position relative to the vehicle edge, and the second end of the first reinforcement 41 may also be connected to the front wall panel assembly 1 at a position relative to the vehicle center. For the provision of the front wall panel 11 upper reinforcement beam or the front wall panel lower reinforcement beam 12 in the front wall panel assembly 1, the second end of the first reinforcement 41 may also be connected to the front wall panel upper reinforcement beam or the front wall panel lower reinforcement beam 12.

Similarly, in the present embodiment, the position where the first end of the second reinforcement 42 is connected to the front side member 2, and the position where the second end of the second reinforcement 42 is connected to the front wall panel 11 are not limited either. For example, the first end of the second reinforcement 42 may be connected to a position of the front side member 2 that is located relatively to the front of the vehicle, and the first end of the second reinforcement 42 may also be connected to a position of the front side member 2 that is located relatively to the rear of the vehicle. More specifically, the first ends of the second reinforcement 42 may also be connected to different sides of the front side member 2. In addition, the second end of the second reinforcement member 42 may be connected to the front wall panel assembly 1 at a position relative to the vehicle edge, and the second end of the second reinforcement member 42 may be connected to the front wall panel assembly 1 at a position relative to the vehicle center. For the provision of the front wall panel upper reinforcement beam or the front wall panel lower reinforcement beam 12 in the front wall panel assembly 1, the second end of the first reinforcement 41 may also be connected to the front wall panel upper reinforcement beam or the front wall panel lower reinforcement beam 12.

On this basis, the second end of the first reinforcement 41 and the second end of the second reinforcement 42 may be connected to the same position of the front wall panel assembly 1, and the second end of the first reinforcement 41 and the second end of the second reinforcement 42 may be connected to different positions of the front wall panel assembly 1, which is not limited in the embodiment of the present application.

Thus, with the above arrangement, in the vehicle body frame provided in the embodiment of the present application, the first reinforcement 41 can form a reinforcing structure between the front wheel cover assembly 3 and the front wall panel assembly 1. On the basis of this, the second reinforcement 42 can form another reinforcing structure between the front side member 2 and the front wall panel assembly 1. Through the reinforced structure formed by the first reinforcing member 41 and the second reinforcing member 42, the stress intensity of the front wall plate assembly 1 can be improved, so that the front wall plate assembly 1 in the embodiment of the application can bear larger collision load, and the front wall plate assembly 1 can be prevented from generating larger deformation during collision, thereby ensuring the safety of drivers and passengers in the cockpit. Meanwhile, in the vehicle body frame provided in the embodiment of the present application, the first reinforcement 41 also forms a path through which the collision force is transmitted between the front side member 2 and the front wall panel assembly 1; the second reinforcement 42 also forms another path through which collision force is transmitted between the front side member 2 and the front wall panel assembly 1. In this way, the vehicle body skeleton provided in the embodiment of the present application can further disperse the collision force, can effectively and stably transmit the collision energy, and can generate deformation at the time of collision of the first reinforcement 41 and the second reinforcement 42 to gradually consume the collision energy, thereby increasing the driving safety of the vehicle. Meanwhile, since the first reinforcement 41 and the second reinforcement 42 disperse the collision force, the maximum stress of the front wall panel assembly 1 can be further reduced, the deformation of the front wall panel assembly 1 can be reduced, and the driving safety can be further ensured.

In addition, in the vehicle body frame provided in the embodiment of the present application, the number of the front side members 2 and the front wheel cover assemblies 3 may be two. The two front side members 2 may be disposed symmetrically with respect to the vehicle longitudinal center line in the vehicle width direction. The two front wheel cover assemblies 3 may also be symmetrically disposed with respect to the center line of the vehicle longitudinal direction in the vehicle width direction. In this regard, in the embodiment of the present application, the front wall panel reinforcement assembly 4 also includes two, and may be disposed symmetrically with respect to the center line of the vehicle length direction in the vehicle width direction. More specifically, the above-described two front side members 2 may be referred to as a left front side member 2 and a right front side member 2, respectively, in terms of the direction relative to the vehicle; the two front wheel cover assemblies 3 are respectively referred to as a left front wheel cover assembly 3 and a right front wheel cover assembly 3; the two front wall panel reinforcement assemblies 4 described above are referred to as a left front wall panel reinforcement assembly 4 and a right front wall panel reinforcement assembly 4, respectively.

For this, in the present embodiment, the left front wall panel reinforcement member 4 may be provided corresponding to the left front side member 2 and the left front wheel cover assembly 3, that is, the first end of the first reinforcement 41 corresponding to the left front wall panel reinforcement member 4 may be connected to the left front wheel cover assembly 3, and the first end of the second reinforcement 42 corresponding to the left front wall panel reinforcement member 4 may be connected to the left front side member 2. Similarly, the right front wall panel reinforcement member 4 is also provided corresponding to the right front side member 2 and the right front wheel cover assembly 3, that is, the first end of the first reinforcement 41 corresponding to the right front wall panel reinforcement member 4 is connected to the right front wheel cover assembly 3, and the first end of the second reinforcement 42 corresponding to the right front wall panel reinforcement member 4 is connected to the right front side member 2.

In the present embodiment, the vehicle body frame provided in the present embodiment is described with the corresponding front side member 2, front wheel cover assembly 3, and front wall panel reinforcement assembly 4 on one side, except for the specific description.

On the other hand, the front side members 2 are provided along the longitudinal direction of the vehicle, and the side surfaces of the front side members 2 are provided in different directions from the front side members 2 in addition to the side surfaces of the front and rear ends of the front side members 2. For example, for simplifying the front side member 2 into a rectangular parallelepiped structure and installing the rectangular parallelepiped structure regularly, the front side member 2 can be considered to have side faces directed upward, downward, left, and right of the vehicle. As for the side surfaces of the front side member 2 facing the left and right of the vehicle, one of the left side surface and the right side surface of the front side member 2 faces one side of the vehicle interior and the other faces one side of the vehicle exterior in the vehicle width direction, as viewed in terms of the positional relationship of the front side member 2 with respect to the vehicle. Illustratively, with respect to the left front side member 2, the right side surface of the left front side member 2 is directed toward one side of the vehicle interior in the vehicle width direction, and the left side surface of the left front side member 2 is directed toward one side of the vehicle exterior in the vehicle width direction.

In addition, in general, a front collision or a side collision is often involved in a collision accident of a vehicle. In response to a frontal collision, the collision force is generally transmitted from the front end of the vehicle toward the inside of the vehicle in the vehicle length direction; in correspondence to a side collision, the collision force is generally transmitted from the left end or the right end of the vehicle toward the vehicle interior in the vehicle width direction.

In order to better provide the front wall panel reinforcement assembly 4 with a reinforcement effect between the front side member 2 and the front wall panel assembly 1, in some embodiments of the present application, the first reinforcement 41 and the second reinforcement 42 are also provided according to the above-described collision force transmission characteristics.

Specifically, referring to fig. 1 and 2, in some embodiments of the present application, the first end of the second reinforcement 42 is connected to the side surface of the front side member 2 toward the vehicle interior side in the vehicle width direction. For convenience of description, a side surface of the front side member 2 toward the vehicle interior side in the vehicle width direction may be referred to as a first side surface 21. Meanwhile, the second end of the second reinforcement 42 is located on the side of the first side 21 facing the vehicle interior.

In the embodiment of the present application, the connection manner between the first end of the second reinforcement member 42 and the first side surface 21 of the front side member 2 is not limited, and the first end of the second reinforcement member 42 may be connected to the front side member 2 by a fastener connection manner, a welding connection manner, or the like, for example. Similarly, in the present embodiment, the connection manner between the second end of the second reinforcement member 42 and the front wall panel assembly 1 is not limited, and the second end of the second reinforcement member 42 may be connected to the front side member 2 by a fastener connection or a welding connection, for example.

On the basis of this, in the present embodiment, the main structure of the first reinforcement 41 is also located on the side of the first side surface 21 of the front side member 2 that faces the vehicle interior. In the first reinforcement 41, the connection structure may be provided at both ends of the first reinforcement 41 for connecting the first end of the first reinforcement 41 to the front side member 2 and the second end of the first reinforcement 41 to the front wall panel assembly 1, and in this regard, the main structure of the first reinforcement 41 may be considered to mean a structure other than the connection structure provided at both ends of the first reinforcement 41.

Specifically, the first end of the first reinforcement 41 may be connected to the side of the front side member 2 that faces upward or downward of the vehicle in the vehicle width direction, and the second end of the second reinforcement 42 may be connected to the side of the front wall panel assembly 1 that faces toward the vehicle interior at the first side 21 of the front side member 2.

Thus, with the above arrangement, the first reinforcement 41 can be made to form a support structure between the front wheel cover assembly 3 and the front wall panel assembly 1 in the longitudinal direction of the vehicle and the width direction of the vehicle; the second reinforcement 42 may be made to form a support structure between the front side member 2 and the front wall panel assembly 1 in the longitudinal direction of the vehicle and the width direction of the vehicle. Meanwhile, the first reinforcement 41 is also capable of forming a force transmission path of collision force between the front wheel cover assembly 3 and the front wall panel assembly 1 in the longitudinal direction of the vehicle and the width direction of the vehicle; the second reinforcement 42 is also capable of forming a force transmission path of collision force between the front side member 2 and the front wall panel assembly 1 in the longitudinal direction of the vehicle and the width direction of the vehicle. Compared with the vehicle body skeleton in the related art, in the vehicle body skeleton provided in the embodiment of the application, a large number of transmission paths for collision force are provided, so that collision energy can be effectively and stably transmitted well. Meanwhile, due to the fact that more transmission paths are arranged, collision energy can be consumed step by step in the collision energy transmission process, and driving safety is improved.

On this basis, in some embodiments of the present application, in order to enhance the supporting effect of the second reinforcement 42, the first end of the second reinforcement 42 and the second end of the second reinforcement 42 are also disposed at the same height.

Specifically, referring to fig. 2, the front side members 2 may be divided into a side with respect to the front of the vehicle and a side with respect to the rear of the vehicle, according to the positional relationship of the front side members 2 with respect to the vehicle in the vehicle length direction. In this regard, in the present embodiment, the first connecting portion is provided on the side of the first side surface 21 corresponding to the rear portion of the vehicle, and the second connecting portion is provided on the front wall panel assembly 1 at a position on the side of the first side surface 21 facing the vehicle interior. Wherein the second connecting portion and the first connecting portion are located at the same height, a first end of the second reinforcing member 42 is fixedly connected to the first connecting portion, and a second end of the second reinforcing member 42 is fixedly connected to the second connecting portion.

The structural form of the first connection portion and the second connection portion is not limited. For example, the first connection portion may be adaptively provided according to the connection manner between the first end of the second reinforcement 42 and the first side surface 21 of the front side member 2, and the second connection portion may be adaptively provided according to the connection manner between the second end of the second reinforcement 42 and the front wall panel assembly 1. Specifically, for the first end of the second reinforcement 42 to be connected to the first side surface 21 of the front side member 2 by means of fastener connection, fastener holes may be provided in the first side surface 21 to achieve a fixed connection between the first end of the second reinforcement 42 and the front side member 2, and for this purpose, the portion of the first side surface 21 where the fastener holes are provided is the first connection portion; for the first end of the second reinforcement 42 to be connected to the first side surface 21 of the front side member 2 by means of a welded connection, a portion for welding may be provided on the first side surface 21, and for this, the portion for welding provided on the first side surface 21 is a first connection portion.

The second connecting portion provided on the front wall panel assembly 1 may also be understood with reference to the foregoing description of the first connecting portion, which is not limited in the embodiment of the present application.

The second connection portion and the first connection portion being located at the same height means that the second connection portion and the first connection portion are located at the same height in the vehicle height direction.

In this way, in the vehicle body frame provided in the embodiment of the present application, the first end of the second reinforcement 42 and the second end of the second reinforcement 42 are disposed to be located at the same height, so that the supporting effect of the second reinforcement 42 between the front side member 2 and the front wall panel assembly 1 can be further improved.

Referring to fig. 2 and 6, in some embodiments of the present application, the second reinforcement 42 is provided in a planar structure, and the main structure of the planar structure is bent into first and second bent portions 421 and 422 that are angled. The first bending portion 421 forms a first end of the second reinforcement 42, and the second bending portion 422 forms a second end of the second reinforcement 42. Wherein, the angle between the first bending part 421 and the second bending part 422 matches the angle between the first connecting part and the second connecting part. Here, the matching of the angle between the first bending portion 421 and the second bending portion 422 and the angle between the first connecting portion and the second connecting portion means that the angle between the first bending portion 421 and the second bending portion 422 is consistent with the angle between the first connecting portion and the second connecting portion.
