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 stated, the terms of orientation such as "front and rear" are used to refer to the front direction of the head of the vehicle and the rear direction of the tail of the vehicle, and specifically, in the present embodiment, in the state shown in fig. 1, the front end is the end facing the head of the vehicle, the rear end is the end facing the tail of the vehicle opposite to the front end, and "outer" refers to the width direction of the vehicle and the direction extending to the outside of the vehicle.
Referring to fig. 1 and 2, according to a first aspect of the present disclosure, an automobile front end structure is provided, which includes a front longitudinal beam 100, an upper longitudinal beam 130, an upper longitudinal beam extension beam 120, and a bumper beam assembly mounting bracket 110, the front longitudinal beam 100 extends along a front-rear direction of an automobile, the upper longitudinal beam 130 gradually extends toward a front lower side of the automobile and is close to the front longitudinal beam 100, a front end of the upper longitudinal beam 130, and a front end 121 of the upper longitudinal beam extension beam 120 are all connected to the bumper beam assembly mounting bracket 110, a rear end 122 of the upper longitudinal beam extension beam 120 is connected to a middle portion of the upper longitudinal beam 130, and a front end of the upper longitudinal beam extension beam 120 is located at an outer side of the front longitudinal beam 100.
Through the technical scheme, the upper longitudinal beam extension beam 120 is additionally arranged, the rear end 122 of the upper longitudinal beam extension beam 120 is connected with the middle part of the upper longitudinal beam 130, and the front end 121 of the upper longitudinal beam extension beam 120 is connected with the bumper beam assembly mounting bracket 110, so that when the automobile is subjected to complete frontal collision and offset collision, acting force generated by collision can be transmitted to the upper longitudinal beam 130 through the upper longitudinal beam extension beam 120, namely the upper longitudinal beam extension beam 120 plays a role in increasing a collision force transmission path, so that the damage force of the collision to a passenger compartment can be reduced, and passengers can be protected; in a small offset collision, because the front end 121 of the upper longitudinal beam extension beam 120 is positioned at the outer side of the front longitudinal beam 100, the acting force generated by the collision can be transmitted to the front longitudinal beam 100 through the front end 121 of the upper longitudinal beam extension beam 120, so that the upper longitudinal beam 130 and the front longitudinal beam 100 can jointly participate in deformation energy absorption, the damage to a passenger compartment is reduced, and the safety performance of the automobile is improved.
In the present embodiment, the main portion of the upper longitudinal beam extension beam 120 gradually bends and extends downward, specifically, the upper longitudinal beam extension beam 120 may include a front end 121, a rear end 122, and a middle portion located between the front end 121 and the rear end 122, and the upper longitudinal beam extension beam 120 gradually bends downward, which may mean that the middle portion gradually bends downward, when a collision occurs, the upper longitudinal beam extension beam 120 further deforms, which is beneficial to increase the absorption of collision energy, and meanwhile, the upper longitudinal beam extension beam 120 may also generate a lateral thrust, which reduces the collision energy borne by the vehicle.
Referring to fig. 1 and 2, the front end 121 of the upper longitudinal beam extension beam 120 is horizontal. Because the upper longitudinal beam extension beam 120 is not integrally bent, and the front end 121 of the upper longitudinal beam extension beam is approximately horizontally arranged, so that the connection part between the front end 121 and the middle part does not continuously bend and extend downwards any more, but the arc transition is horizontal, compared with the case that the front end 121 of the upper longitudinal beam extension beam 120 continuously bends and extends downwards and is connected to the bumper beam assembly mounting bracket 110, the relative height of the front end 121 of the upper longitudinal beam extension beam 120 can be reduced, that is, the occupation of the front end 121 of the upper longitudinal beam extension beam 120 on the installation space of the front headlamp of the cabin is reduced, so that the installation of the front headlamp of the cabin and other components can be facilitated.
Referring to fig. 1 and 2, in the present embodiment, the upper longitudinal beam extension beam 120 is configured as a variable cross-section structure, and the cross-sectional area of the upper longitudinal beam extension beam 120 gradually increases from the rear end 122 of the upper longitudinal beam extension beam 120 to the front end 121, that is, the cross-sectional area of the front end 121 of the upper longitudinal beam extension beam 120 is larger than the cross-sectional area of the rear end 122, and the cross-sectional area of the upper longitudinal beam extension beam 120 gradually decreases from the front to the rear of the automobile.
In this embodiment, the upper longitudinal beam extension beam 120 is configured to be a hollow structure, and the cross-sectional shape of the upper longitudinal beam extension beam is rectangular, and the upper longitudinal beam extension beam 120 is configured to be a hollow structure and the cross-sectional shape of the upper longitudinal beam extension beam is rectangular, rather than a solid structure, so that the upper longitudinal beam extension beam 120 can not only save the manufacturing materials of the vehicle body, but also meet the requirement of the vehicle for light weight while meeting the requirement of rigidity and strength.
In a specific implementation, the upper longitudinal beam extension beam 120 may be welded together by two sheet metal parts.
In this embodiment, the front end 121 of the upper longitudinal beam extension beam 120 is attached to the front end of the front longitudinal beam 100, that is, the front end 121 of the upper longitudinal beam extension beam 120 is attached to the front end of the front longitudinal beam 100, where the attachment means that the inner side surface of the front end 121 of the upper longitudinal beam extension beam 120 is attached to the outer side surface of the front end of the front longitudinal beam 100, and of course, the inner side surface of the front end 121 of the upper longitudinal beam extension beam 120 may be spaced from the outer side surface of the front end of the front longitudinal beam 100 by a certain distance, but not completely attached, for example, the distance may be 0.1cm to 0.3 cm. When a full frontal collision or a neutral offset collision occurs, the collision force can be quickly transmitted to the front end 121 of the upper-side-member extension beam 120 via the front end of the front side member 100, thereby increasing the energy transmission path.
In this embodiment, the front end of the front longitudinal beam 100, the front end of the upper longitudinal beam 130, and the front end 121 of the upper longitudinal beam extension beam 120 are all welded to the bumper beam assembly mounting bracket 110, and the connection stability between the front longitudinal beam 100, the upper longitudinal beam 130, the upper longitudinal beam extension beam 120, and the bumper beam assembly mounting bracket 110 can be ensured by welding, so as to ensure the stability of the vehicle body.
According to a second aspect of the present disclosure, there is provided an automobile including the automobile front end structure described above. In which, fig. 1 and fig. 2 show only a structure on one side of the front end of the vehicle body, not an integral structure of the front end of the vehicle body, the integral structure of the front end of the vehicle body includes two front end structures of the vehicle, and the two front end structures of the vehicle are arranged symmetrically to each other, that is, each vehicle includes two front end structures of the vehicle arranged symmetrically.
