技术领域technical field

本公开涉及汽车领域，特别涉及一种车身前部结构和汽车。The present disclosure relates to the field of automobiles, and in particular, to a vehicle body front structure and an automobile.

背景技术Background technique

汽车的车身前部结构在汽车碰撞时可以吸收能量，减少向乘员舱传递的载荷力，降低乘员受伤的可能性。The front body structure of the car can absorb energy when the car collides, reducing the load force transmitted to the passenger compartment and reducing the possibility of occupant injury.

车身前部结构包括前保险杠、前纵梁以及连接保险杠和前纵梁的吸能盒。在汽车碰撞时前保险杠将载荷力传递给吸能盒，吸能盒溃缩变形，使载荷力减小，然后将剩余的载荷力传递给前纵梁，前纵梁再将载荷力传递给乘员舱。The front structure of the vehicle body includes a front bumper, a front longitudinal beam, and an energy-absorbing box connecting the bumper and the front longitudinal beam. When the car collides, the front bumper transmits the load force to the energy-absorbing box, and the energy-absorbing box collapses and deforms to reduce the load force, and then transmits the remaining load force to the front longitudinal beam, and the front longitudinal beam transmits the load force to the Crew cabin.

虽然吸能盒通过溃缩变形可以吸收部分载荷力，减小传递给乘员舱的载荷力。但汽车的车身前部结构的吸能效果仍然不够好，驾驶员在碰撞时容易受伤。Although the energy-absorbing box can absorb part of the load force through the collapse deformation, reducing the load force transmitted to the passenger compartment. However, the energy absorption effect of the front body structure of the car is still not good enough, and the driver is easily injured in the collision.

本公开实施例提供的技术方案带来的有益效果是：The beneficial effects brought by the technical solutions provided by the embodiments of the present disclosure are:

在本公开实施例中，前保险杠、吸能盒、吸能盒连接板、第一前纵梁和角撑构件共同组成本申请中的车身前部结构。吸能盒位于前保险杠和第一前纵梁之间。在汽车碰撞时，前保险杠受到撞击，前保险杠将载荷力传递给吸能盒，吸能盒溃缩吸能，减小载荷力。由于角撑构件连接吸能盒连接板和第一前纵梁，且角撑构的一端在第二表面上的正投影与吸能盒的另一端在第二表面上的正投影至少部分重合，吸能盒将一部分载荷力直接传递给第一前纵梁，吸能盒将另一部分载荷力传递给角撑构件，角撑构件也能够吸收部分能量，使载荷力减小。角撑构件再将载荷力传递给第一前纵梁。由于角撑构件的存在，在吸能盒吸能的基础上，角撑构件也会吸收部分能量，进一步减小传递给第一前纵梁的载荷力，增加车身前部结构的吸能作用。从而减小第一前纵梁向乘员室传递的载荷力，减小乘员受伤的可能性。同时，传递给第一前纵梁的载荷力减小，减小第一前纵梁由于载荷力过大造成的变形的可能性，避免第一前纵梁变形影响汽车的安全性。In the embodiment of the present disclosure, the front bumper, the energy absorbing box, the connecting plate of the energy absorbing box, the first front longitudinal beam and the gusset member together constitute the front structure of the vehicle body in the present application. The energy absorption box is located between the front bumper and the first front side member. When the car collides, the front bumper is hit, and the front bumper transmits the load force to the energy-absorbing box, and the energy-absorbing box collapses to absorb energy and reduce the load force. Since the gusset member connects the energy-absorbing box connecting plate and the first front longitudinal beam, and the orthographic projection of one end of the gusset structure on the second surface and the orthographic projection of the other end of the energy-absorbing box on the second surface at least partially coincide, The energy-absorbing box directly transmits a part of the load force to the first front longitudinal beam, and the energy-absorbing box transmits another part of the load force to the gusset members, which can also absorb part of the energy to reduce the load force. The gussets then transmit the load force to the first front longitudinal member. Due to the existence of the gusset members, on the basis of energy absorption by the energy-absorbing box, the gusset members will also absorb part of the energy, further reducing the load force transmitted to the first front longitudinal beam, and increasing the energy-absorbing effect of the front body structure. Therefore, the load force transmitted by the first front longitudinal member to the passenger compartment is reduced, and the possibility of injury to the passenger is reduced. At the same time, the load force transmitted to the first front longitudinal beam is reduced, the possibility of deformation of the first front longitudinal beam due to excessive load force is reduced, and the deformation of the first front longitudinal beam is prevented from affecting the safety of the vehicle.

第一前纵梁40沿第二方向b延伸。第一前纵梁40和角撑构件50位于吸能盒连接板30的第二表面32。第一前纵梁40的一端与吸能盒连接板30的第二表面32相连，且连接处对应两个吸能盒20中的一个。角撑构件50的一端与吸能盒连接板30的第二表面32连接，且连接处对应两个吸能盒20中的另一个。角撑构件50的另一端与第一前纵梁40的侧壁相连。The first front side member 40 extends in the second direction b. The first front side member 40 and the gusset member 50 are located on the second surface 32 of the energy absorbing box connecting plate 30 . One end of the first front longitudinal beam 40 is connected to the second surface 32 of the energy absorbing box connecting plate 30 , and the connection corresponds to one of the two energy absorbing boxes 20 . One end of the gusset member 50 is connected to the second surface 32 of the energy-absorbing box connecting plate 30 , and the connection corresponds to the other of the two energy-absorbing boxes 20 . The other end of the gusset member 50 is connected to the side wall of the first front side member 40 .
