[0002] Currently, problems such as bending and cracking of the A-pillar often occur in small offset collisions of vehicles, and the design requirements for the vehicle's A-pillar are relatively high. In order to reduce the impact of the collision force on the A-pillar in small offset collisions, the existing front cabin body structure mostly adopts a structural energy absorption design strategy to reduce the collision force transmitted to the A-pillar, such as designing a shotgun beam (also called an upper longitudinal beam) and a front longitudinal beam to absorb collision energy. However, due to the lack of a lateral force transmission structure, most of the offset collision force will still be transmitted to the A-pillar, and the actual effect is limited, and the design requirements for the A-pillar are still relatively high. Therefore, it is urgent to provide a new structure to reduce the impact on the A-pillar in small offset collisions, thereby reducing the design requirements for the A-pillar, reducing costs, and improving the collision performance of the entire vehicle.

DETAILED DESCRIPTION

[0021] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention, and the following embodiments and the features in the embodiments can be combined with each other without conflict.

[0022] It should be noted that the “lateral” mentioned below refers to the width direction of the vehicle, and the “longitudinal” refers to the front and rear direction of the vehicle, with the front side of the vehicle being the front and the rear side being the rear.

[0023] See also Figure 1-3 This embodiment discloses a side-slip structure for a vehicle in a small offset collision, comprising:

[0024] The front longitudinal beam assembly includes two sets of front longitudinal beams 1. The front longitudinal beams 1 are usually formed by butting and fastening an inner plate and an outer plate. The two sets of front longitudinal beams 1 are symmetrically arranged in the front cabin of the vehicle. The design can refer to the existing structure of the front longitudinal beams 1, which will not be described here.

[0025] The SHOTGUN structure includes two groups of SHOTGUN beams 2, the rear section of the SHOTGUN beam 2 is fixedly connected to the corresponding side A-pillar 3, and the front section of the SHOTGUN beam 2 is fixedly connected to the corresponding side front longitudinal beam 1 through a connecting component 4. Here, the rear section of the SHOTGUN beam 2 is usually welded and fixed to the upper end of the A-pillar 3, and the connecting component 4 is preferably a connecting plate structure, and the fixed connection of the corresponding parts can be completed by welding;

[0026] The tower package assembly includes two groups of tower packages 5 and tower package cross beams 6. The tower package 5 is fixed between the corresponding side SHOTGUN beam 2 and the front longitudinal beam 1. Both ends of the tower package cross beam 6 are fixedly connected to the corresponding side tower package 5. Transverse force transmission members 7 adjacent to or attached to the corresponding side tower package 5 are respectively arranged at both ends of the tower package cross beam 6. Usually, a small process gap is set between the transverse force transmission member 7 and the tower package 5. It can be understood that the tower package 5 here is a front shock absorber tower package, which is generally fixed to the SHOTGUN beam 2 and the front longitudinal beam 1 by welding, and the tower package cross beam 6 is generally fixed to the tower package 5 by bolts.

[0027] In the above structural design, the front longitudinal beam assembly and the SHOTGUN structure are designed as longitudinal force transmission and energy absorption structures for small offset collisions, which can absorb part of the collision force; a connection assembly 4 is set between the front section of the SHOTGUN beam 2 and the front longitudinal beam 1 to ensure the reliability of the overall force transmission structure, and at the same time, the tower package cross beam 6 set between the tower packages 5 can effectively improve the lateral transmission of the collision force during a small offset collision. When the connection point of the tower package cross beam 6 fails, the lateral force transmission member 7 completes the lateral transmission of the collision force. The tower package cross beam 6 and the lateral The support of the force transmission member 7 greatly reduces the lateral tilting of the tower package, making the lateral thrust greater, and the tower package generates the largest lateral thrust; in this way, it is conducive to the lateral sliding of the whole vehicle during a small offset collision, so that the whole vehicle slides sideways before the obstacle avoider hits the A-pillar 3, and the whole vehicle is basically separated from the obstacle avoider when it reaches the A-pillar. The A-pillar avoids bending and cracking due to the great impact energy absorption; thereby reducing the high design requirements for the A-pillar (such as reducing the plate thickness, reducing the A-pillar molding process, etc.) to a certain extent, reducing costs and improving the collision performance of the whole vehicle.

[0028] In this embodiment, the transverse force transmission member 7 is a force transmission block fixed to the lower end of the tower package cross beam 6, and the transverse force transmission member 7 is welded and fixed to the tower package cross beam 6; it is reasonably positioned at the lower end of the tower package cross beam 6, which is conducive to forming abutment with the tower package 5 and has a good force transmission effect; the force transmission block has a simple structure and reliable strength.

[0029] In this embodiment, the middle section of the tower bag crossbeam 6 is fixedly connected with a longitudinal support beam 8, and the rear end of the longitudinal support beam 8 is fixedly connected to the vehicle front panel assembly 9; specifically, the longitudinal support beam 8 is welded and fixed to the tower bag crossbeam 6, and the rear end of the longitudinal support beam 8 can usually be welded or screwed to the front panel 902 of the front panel assembly 9 to complete the fixation; in this structural design, the longitudinal support beam 8 can prevent the tower bag 5 and the tower bag crossbeam 6 from moving longitudinally backward under a small offset obstacle avoidance impact, thereby avoiding the tower bag 5 from tipping backward, which is beneficial to further provide sufficient side thrust for the tower bag 5, so that the whole vehicle slides laterally under the push of the tower bag 5, and finally causes the obstacle avoidance to hit the front side of the A-pillar 3 to push the whole vehicle away, thereby avoiding direct impact on the A-pillar 3 and further improving the side sliding effect of the whole vehicle.

[0030] In this embodiment, the longitudinal support beam 8 is arranged obliquely upward and backward from the tower package cross beam 6 and is fixedly connected to the front enclosure assembly 9 through a connecting bracket 801. The connecting bracket 801 includes an upper connecting plate 801a and a lower connecting plate 801b fixed to each other. The upper connecting plate 801a is fixedly connected to the front windshield lower cross beam 901 of the front enclosure assembly 9, and the lower connecting plate 801b is fixedly connected to the front enclosure plate 902 of the front enclosure assembly 9; oblique reinforcing beams 10 are respectively provided on both sides of the transverse direction of the longitudinal support beam 8; here, the fixing method between the upper connecting plate 801a and the lower connecting plate 801b is not limited, such as welding or screwing, etc. Of course, in other embodiments, the upper connecting plate 801a and the lower connecting plate 801b can also be an integrated structure, or the upper connecting plate 801a and the lower connecting plate 801b are respectively fixed to the longitudinal support beam 8; Similarly, here, the fixing method of the upper connecting plate 801a and the lower cross beam 901 of the front windshield is not limited, and the fixing method of the lower connecting plate 801b and the front panel 902 is not limited; here, the oblique reinforcing beam 10 is welded and fixed to the longitudinal support beam 8 and the tower package cross beam 6 respectively to form a triangular reinforcement structure; in this structural design, by designing the connecting bracket 801, it is convenient to complete the connection between the longitudinal support beam 8 and the front panel assembly 9, wherein the design of the upper connecting plate 801a and the lower connecting plate 801b is convenient to disperse the transmission force of the longitudinal support beam 8 to the lower cross beam 901 of the front windshield and the front panel 902, the force transmission is reliable, and it is convenient to reduce the impact on a single component in the front panel assembly 9 and reduce the impact damage to the front panel assembly 9; by designing the oblique reinforcing beam 10, it is convenient to improve the overall structural strength of the tower package cross beam 6 and avoid deformation and failure during a small offset collision.

[0031] In the present embodiment, a front end frame cross beam 11 is also included, and both ends of the front end frame cross beam 11 are fixedly connected to the SHOTGUN beam 2 on the corresponding side. Specifically, the front end frame cross beam 11 is welded and fixed to the SHOTGUN beam 2. By fixing the front end frame cross beam 11 to the SHOTGUN beam 2, a new lateral force transmission path is formed, which reduces the deformation of the front section of the SHOTGUN beam 2, and further enables the SHOTGUN beam 2 to provide a greater lateral thrust, so that the whole vehicle has an obvious lateral offset in the early stage, and the side sliding effect of the whole vehicle is further improved. In addition, the cross beam of the front end frame is used, and the structure is compact.

[0032] In this embodiment, the two ends of the front end frame beam 11 are overlapped and fixed to the upper end of the SHOTGUN beam 2; the front end frame beam 11 is arranged at the upper end of the SHOTGUN beam 2, which is beneficial to use the SHOTGUN beam 2 to complete the support of the front end frame beam 11, and is beneficial for the front end frame beam 11 to have reliable bearing capacity, providing a bearing position for other components of the front end module.

[0033] In this embodiment, the connecting component 4 is a connecting plate with a cavity structure therein. The connecting plate can be an integral structure, or a plurality of plates can be welded to form a cavity structure. The structure is reliable and can play a certain energy absorption role. The lower end of the connecting plate is fixedly connected to the upper end of the front longitudinal beam 1, and the upper end of the connecting plate is fixedly connected to the lower end of the SHOTGUN beam 2. The structure is simple and the supporting effect is good.

[0034] In this embodiment, the tower package crossbeam 6 is a rectangular beam with a simple structure and good structural strength. Reinforcement blocks 601 are fixed inside the two ends of the rectangular beam, such as by welding. The reinforcement blocks 601 are provided with connecting holes 601a. ​​The design of the reinforcement blocks 601 is conducive to improving the structural strength of the connection point between the tower package crossbeam 6 and the tower package 5, and is conducive to further improving the reliability of force transmission of the tower package crossbeam 6, preventing the tower package 5 from lateral deformation and tipping over. The design of the connecting holes 601a is conducive to the rapid installation of the tower package crossbeam 6 and the tower package 5 by bolts.

[0035] In this embodiment, a plurality of reinforcing plates 201 are provided at intervals in the inner cavity of the SHOTGUN beam 2. Usually, the SHOTGUN beam 2 also has a cavity structure formed by welding an inner plate and an outer plate. By arranging a plurality of reinforcing plates 201 in the inner cavity, it is beneficial to improve the overall structural strength of the SHOTGUN beam 2, and improve the durability and reliability of use.
