Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, the use of directional terms such as "upper, lower, left, right, front, and rear" generally refers to upper, lower, left, right, front, and rear of a vehicle during normal driving, and "inner and outer" refer to inner and outer relative to the contour of the corresponding component itself. The terms "first," "second," and the like, as used in this disclosure, are intended to distinguish one element from another, and not necessarily for sequential or importance. In addition, when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

In order to achieve the above object, the present disclosure provides a vehicle front cabin assembly, as shown in fig. 1 to 6, which may include two front side members 1, a structural beam 2, and a joint 3, wherein the two front side members 1 extend in a front-rear direction of a vehicle on both sides of the vehicle, the structural beam 2 is disposed between the two front side members 1, and the structural beam 2 extends in a left-right direction of the vehicle, the joint 3 is connected between an end portion 21 of the structural beam 2 and the front side members 1, and enables the end portion 21 and the front side members 1 to have a crush gap 4 in the left-right direction, the strength of the joint 3 is smaller than that of the structural beam 2, so that the joint 3 is more easily deformed and broken than the structural beam 2, wherein, as shown in fig. 4 to 6, the front side members 1 may be configured to: when an impact is applied from the front side of the vehicle, the portion of the front side member 1 connected to the joint 3 can be bent toward the vehicle interior side and crush the joint 3, so that the first section 11 of the front side member 1 on the front side of the joint 3 extends obliquely from front to rear toward the vehicle interior side.

Through the technical scheme, in the vehicle front cabin assembly provided by the disclosure, because the strength of the joint 3 is smaller than that of the structural beam 2, when the front longitudinal beam 1 is impacted from the front side and collapses, the joint 3 can be extruded and deformed, and the collapse gap 4 can be reduced or even disappeared, so that a space can be provided for the inclined extension of the first section 11 towards the inner side of the vehicle, the bending angle of the part of the front longitudinal beam 1 connected with the joint 3 is increased, the collapse stroke of the front longitudinal beam 1 is increased, so that more impact force can be absorbed in the collapse process, and the injury to drivers and passengers caused by insufficient collapse energy absorption is reduced.

Referring to fig. 1 and 4, the front cabin assembly may further include a front impact beam 5 connected to front ends of the two front side members 1, the first section 11 is connected between the front impact beam 5 and the joint 3, the front side member 1 may further include a reinforcing rib 13 disposed between the front impact beam 5 and an outer side of the first section 11, and the reinforcing rib 13 has a triangular structure. Due to the presence of the reinforcing rib 13, the strength of the connection between the inner side of the first section 11 and the front impact beam 5 is weaker than the strength of the connection between the outer side of the first section 11 and the front impact beam 5, and therefore, when an impact from the front side of the vehicle is received, the connection between the inner side of the first section 11 and the front impact beam 5 is deformed, and the first section 11 can extend obliquely from the front to the rear toward the inner side.

In order to provide the crush gap 4 between the structural beam 2 and the front side member 1, as shown in fig. 2, the joint 3 may be configured as an i-beam, which may have a first recess 31 and a second recess 32 opposite to each other in the left-right direction, the first recess 31 near the vehicle outer side being fixedly connected to the front side member 1, and the second recess 32 near the vehicle inner side being fixedly connected to the end portion 21, so that the front side member 1 is spaced apart from the end portion 21 to form the crush gap 4 in the left-right direction. Furthermore, the joint 3 configured as an i-beam has a smaller cross-sectional area and thus has less strength than the structural beam 2 configured as a solid structure described below.

In order to improve the connection reliability of the front side member 1 and the engaging member 3, as shown in fig. 2, the upper surface of the front side member 1 may be fixedly connected to the upper wall of the first recess 31, and the lower surface of the front side member 1 may be fixedly connected to the lower wall of the first recess 31, so as to increase the contact area between the front side member 1 and the engaging member 3.

Referring to fig. 1 and 4, the front cabin assembly may further include a lower front wall cross member 6 connected to rear ends of the two front side members 1, the front side members 1 further include a second section 12 connected between the joint member 3 and the lower front wall cross member 6, when the collapse gap 4 completely disappears, so that the rear end of the first section 11 abuts against the structural beam 2 having a larger strength, the structural beam 2 can provide a reverse supporting force toward the vehicle outer side for the rear end of the first section 11 and the front end of the second section 12, the first section 11 can stop extending obliquely toward the vehicle inner side under the reverse supporting force, as shown in fig. 5, as a specific embodiment, when the impact force applied to the vehicle front side is larger, and the reverse supporting force is larger, the middle portion of the second section 12 can bend toward the vehicle outer side under the reverse supporting force, so as to further increase the collapse stroke of the front side members 1, referring to fig. 6, as another embodiment, when the vehicle front side is slightly impacted so that the reverse supporting force is small, the middle portion of the second section 12 may not be bent, but the second section 12 may be entirely extended obliquely from the front to the rear toward the vehicle outer side by the reverse supporting force, so that the crush stroke of the front side member 1 is increased.

Referring to fig. 1 and 4, in order to prevent the front side member 1 from being compressed during collapse of the rigid structure such as the power module in the front cabin assembly, which is generally accommodated between the structural beam 2 and the cowl cross member 6, the length of the second section 12 may be greater than that of the first section 11, so that a space sufficient to accommodate the rigid structure remains between the structural beam 2 and the cowl cross member 6 even after collapse of the second section 12.

In order to enable the structural beam 2 and the front longitudinal beam 1 to be fixedly connected with the joint 3 respectively, the structural beam 2 and the joint 3 can be fixed by welding or connected by a fastener, and the front longitudinal beam 1 and the joint 3 can be fixed by welding or connected by a fastener.

In order to provide the structural beam 2 with a greater strength, the structural beam 2 may be of solid construction, and the cross section of the structural beam 2 is a closed section, for example a box section. Further, the structural beam 2 may be made of a high-strength steel plate or a solid iron pipe, or may be made of a hardened material such as a forged material.

In order to make the engaging member 3 easily press-deformed, the engaging member 3 may be made of iron, aluminum, or a resin material.

Further, referring to fig. 3, the front side member 1 may include a side member body 101 extending in the front-rear direction and a shock-absorbing tower 102 fixedly coupled to an upper surface of the side member body 101, and when the side member body 101 is not conveniently fixedly coupled directly to the coupling member 3, the coupling member 3 may also be fixedly coupled between the shock-absorbing tower 102 and the structural beam 2.

On the basis of the technical scheme, the present disclosure further provides a vehicle, which is shown in fig. 7 and includes the vehicle front cabin assembly in the technical scheme.

Through the technical scheme, the vehicle provided by the disclosure has the same technical effect as the vehicle front cabin assembly in the technical scheme, and unnecessary repetition is avoided, so that the detailed description is omitted.
