[0002] The proportion of frontal car collisions in daily traffic accidents is relatively high. At present, the standards and regulations for frontal high-speed car collision tests at home and abroad are mainly based on 0° angle impact barriers, while the only angle high-speed collisions are the 30° oblique collision in the US FMVSS208 regulations and the Oblique Offset Moving Deformable Barrier (OMDB) test launched by the US Highway Safety Administration NHTSA.

[0053] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0054] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0055] like Figures 1 to 11As shown, the front cabin assembly 100 of the vehicle body of the embodiment of the present invention includes a front longitudinal beam 1, an upper side beam column 1, an upper side beam 3 and an oblique support beam 4. The upper side beam column 1 is arranged on the front longitudinal beam 1, the upper side beam 3 is spaced apart from the front longitudinal beam 1 in the height direction of the vehicle body, and the upper side beam 3 is connected to the upper side beam column 1. One end of the oblique support beam 4 is connected to at least one of the upper side beam 3 and the upper side beam column 1, and the other end of the oblique support beam 4 is connected to the front longitudinal beam 1. On the projection plane orthogonal to the height direction of the vehicle body, the oblique support beam 4 extends in the direction from the rear side of the vehicle body to the front side of the vehicle body and is inclined in the width direction of the vehicle body toward a direction away from the front longitudinal beam 1.

[0056] One end of the oblique support beam 4 is connected to at least one of the upper side beam 3 and the upper side beam column 1. It can be understood that one end of the oblique support beam 4 can be connected only to the upper side beam 3, or one end of the oblique support beam 4 can be connected only to the upper side beam column 1, or one end of the oblique support beam 4 can be connected to both the upper side beam column 1 and the upper side beam 3. Figure 1 and Figure 2 As shown, the oblique support beams 4 are connected to the upper side beam columns 1 and the upper side beams 3 by welding.

[0057] When the OMDB test is performed in the embodiment of the present invention, that is, the mobile barrier trolley collides with the front cabin assembly 100 of the stationary test vehicle at a speed of 90 km / h at an angle of 15°, and the overlap rate between the test vehicle and the barrier trolley is 35%. During the test, the barrier trolley will collide with the upper side beam column 1 and the upper side beam 3, so that the upper side beam column 1 and the upper side beam 3 will be subjected to an impact force at an angle of 15° with the front-rear direction. Since an oblique support beam 4 is provided between the upper side beam column 1 and the front longitudinal beam 1, and on a projection plane orthogonal to the height direction of the vehicle body, the oblique support beam 4 extends from the rear side to the front side of the vehicle body and is inclined in the width direction of the vehicle body in a direction away from the front longitudinal beam 1, the oblique support beam 4 supports at least one of the upper side beam column 1 and the upper side beam 3, forming an angle collision frontal force transmission path to enhance the lateral collision force borne by the upper side beam column 1 and the upper side beam 3, allowing the vehicle to deflect and slide out during an angle collision, avoiding a large structural deformation of the front cabin assembly 100 of the vehicle body, reducing the intrusion into the passenger compartment, protecting the safety of passengers in the vehicle, and improving riding safety.

[0058] Therefore, the front compartment assembly 100 of the vehicle body according to the embodiment of the present invention has advantages such as good safety.

[0059] In some embodiments, the front cabin assembly 100 of the vehicle body of the embodiment of the present invention also includes a shock-absorbing tower 5, which is arranged on the front longitudinal beam 1, and the upper side beam column 1 is located on the front side of the shock-absorbing tower 5, the two ends of the upper side beam 3 are respectively connected to the shock-absorbing tower 5 and the upper side beam column 1, and the other end of the diagonal support beam 4 is connected to the shock-absorbing tower 5.

[0060] In order to facilitate the description of the technical solution of the present application, the following takes the length direction of the vehicle body as being consistent with the front-to-back direction, the width direction of the vehicle body as being consistent with the left-to-right direction, and the height direction of the vehicle body as being consistent with the up-to-down direction as an example to further describe the technical solution of the present application, wherein the up-to-down direction, the front-to-back direction, and the left-to-right direction are as follows: Figures 1 to 11 shown.

[0061] For example, Figure 1 and Figure 2 As shown, the front end of the oblique support beam 4 is welded to the upper side beam column 1 and the upper side beam 3 respectively, and the rear end of the oblique support beam 4 is welded to the shock tower 5, so that the upper side beam 3, the oblique support beam 4 and the shock tower 5 form the main force transmission path for angle collision.

[0062] In some embodiments, the front longitudinal beam 1 includes a first front longitudinal beam 101 and a second front longitudinal beam 102, the first front longitudinal beam 101 and the second front longitudinal beam 102 are arranged at intervals in the width direction of the vehicle body, and the shock tower 5 is arranged on at least one of the first front longitudinal beam 101 and the second front longitudinal beam 102. The front compartment assembly 100 of the vehicle body also includes a connecting rod 6, and both ends of the connecting rod 6 are connected to the first front longitudinal beam 101 and the second front longitudinal beam 102 respectively.

[0063] For example, Figures 1 to 11 As shown, the first front longitudinal beam 101 and the second front longitudinal beam 102 are arranged at intervals in the left-right direction. By arranging the connecting rod 6 between the first front longitudinal beam 101 and the second front longitudinal beam 102, when a collision occurs on one side of the vehicle, the collision force borne by the front cabin assembly 100 will be transmitted to the other side of the vehicle through the connecting rod 6 to decompose the collision force, which is beneficial to enhancing the lateral collision force borne by the front cabin assembly 100 during the collision process, and is beneficial to improving the safety of the front cabin assembly 100 of the vehicle body of the embodiment of the present invention.

[0064] In some embodiments, the shock tower 5 includes a first shock tower 501 and a second shock tower 502, wherein the first shock tower 501 is disposed on the first front longitudinal beam 101, and the second shock tower 502 is disposed on the second front longitudinal beam 102. The connecting rod 6 includes a first connecting rod 601 and a second connecting rod 602, wherein both ends of the first connecting rod 601 are respectively connected to the first shock tower 501 and the second shock tower 502, and both ends of the second connecting rod 602 are respectively connected to the first front longitudinal beam 101 and the second front longitudinal beam 102.

The front end of the second oblique support beam is respectively welded to the second upper side beam 302 and the second upper side beam column 202, and the rear end of the second oblique support beam is welded to the second shock tower 502.

[0066] Specifically, when the right side of the front cabin assembly 100 collides, the collision force on the first upper side beam 301 and the first pillar 201 will be divided into two forces, one force will be transmitted to the first shock absorbing tower 501 through the first oblique support beam, and then the first shock absorbing tower 501 will be transmitted to the first connecting rod 601, and the first connecting rod 601 will be transmitted to the second shock absorbing tower 502 to decompose the collision force. The other force will be transmitted to the second front longitudinal beam 102 through the second connecting rod 602 to decompose the collision force.

[0067] Therefore, by setting the first connecting rod 601 between the first shock-absorbing tower 501 and the second shock-absorbing tower 502 to form a rear end lateral force transmission path, and setting the second connecting rod 602 between the first front longitudinal beam 101 and the second front longitudinal beam 102 to form a front end lateral force transmission path, a double-sided inward transmission path is formed.

[0095] For example, the first connecting rod 601 is an aluminum alloy extruded beam with a closed cavity, which has optimal performance and lightweight efficiency.

[0096] Optionally, the second connecting rod 602 has a third collapse chamber 6023 .

[0097] For example, the second connecting rod 602 is an aluminum alloy extruded beam with a closed cavity, which has optimal performance and lightweight efficiency.

[0098] In some embodiments, the oblique support beam 4 includes an inner plate 403 and an outer plate 404 connected to each other, and a first collapse chamber 405 is defined between the inner plate 403 and the outer plate 404 .

[0099] For example, Figure 7 As shown, the inner plate 403 and the outer plate 404 of the oblique support beam 4 are connected by welding, and a first collapse chamber 405 is defined between the inner plate 403 and the outer plate 404. When the oblique support beam 4 is subjected to force, it can collapse to absorb energy, thereby reducing the amount of intrusion into the passenger compartment, which is further beneficial to improving the safety of the front cabin assembly 100 of the vehicle body of the embodiment of the present invention.

[0100] In some embodiments, the front cabin assembly 100 of the vehicle body of the embodiment of the present invention also includes a double wishbone 13, and the shock tower 5 has a front mounting point 503 and a rear mounting point 504 spaced apart in the length direction of the vehicle body, the front mounting point 503 and the rear mounting point 504 are used to install the double wishbone 13, and the extension direction of the diagonal support beam 4 intersects with the front mounting point 503.

[0101] For example, Figures 6 to 8As shown, the double wishbone 13 includes a first double wishbone 1301 and a second double wishbone 1302. The first double wishbone 1301 is installed on the first shock tower 501 through a front mounting point 503 and a rear mounting point 504 on the first shock tower 501, and the second double wishbone 1302 is installed on the second shock tower 502 through a front mounting point 503 and a rear mounting point 504 on the second shock tower 502. By intersecting the extension direction of the oblique support beam 4 with the front mounting point 503, when the collision force borne by the oblique support beam 4 can be transmitted to the first link 601 and the double wishbone 13 in the left and right directions respectively, the collision force is transmitted to the double wishbone 13 through the front mounting point 503, and the NVH performance of the vehicle body near the front mounting point 503 is improved, thereby further enhancing the lateral bearing capacity of the vehicle, which is further conducive to improving the safety of the front cabin components.

[0102] Optionally, the extension direction of the first link 601 intersects with the front mounting point 503 of the shock tower 5, so that the diagonal support beam 4 can quickly and efficiently transfer the collision force it bears to the first link 601 and the double wishbone 13. The first link 601 not only plays a role in lateral transmission of the collision force, but also improves the NVH performance of the shock tower 13.
