Description
Technical Field
The utility model belongs to the technical field of automobile bodies, and particularly relates to a safe automobile body structure and an automobile.
Background
The collision safety of the automobile is reflected in the accident process and after the accident, and the damage performance of passengers can be reduced to the greatest extent.
Currently, this is achieved mainly by three approaches. First, damage is reduced by improving crashworthiness of the vehicle. The measures for achieving this are now: the front part and the rear part of the vehicle body are additionally provided with collision buffer areas and bumpers, and a suspension engine anti-collision protection device is adopted, so that the rigidity of the cockpit is improved. Secondly, the passenger and the automobile can synchronously move by controlling the movement of the passenger in the collision process, so that impact damage and secondary collision damage to objects in the cockpit are reduced. This function may be achieved with an occupant restraint system. Common occupant restraint systems include: safety belt, headrest, etc. Third, by reducing the contact stiffness between the human body and the cabin interior components, the contact area is increased to reduce damage from a secondary collision. The automobile safety protection device can be realized by adopting the scheme of adopting the safety airbag to reduce the rigidity of an instrument panel, an inner decoration and the like.
As shown in fig. 3, the existing GOA safety car body is of a monolithic structure, and during collision, impact force in the horizontal direction is transmitted to the passenger cabin along the front longitudinal beam or the rear longitudinal beam, so that passengers can receive large horizontal force impact, and large impact injuries can be caused to the head, the cervical vertebrae and the viscera. If the impact force is too large and exceeds the upper limit of the collapse energy absorption of the front and rear vehicle bodies, the excessive impact force can act on the vehicle body of the passenger cabin, so that the passenger cabin is deformed, and the passengers can be injured by extrusion.
The structural characteristics of the existing GOA safety car body are as follows: front and rear impact deformation zones and a high strength passenger compartment. The basic requirement for the front and rear impact deformation zone is to have a soft energy absorbing zone to absorb more energy when an impact occurs. In a frontal collision, the greater the deformation of the deformation energy absorbing region of the front and rear portions of the vehicle body, the more collision energy is absorbed, and the less energy is generated in the secondary collision, so that the smaller the impact force transmitted into the passenger compartment. Meanwhile, the vehicle body adopts the high-strength passenger room, so that the deformation strength of the passenger room after collision can be effectively enhanced, and the problem that passengers are extruded due to the deformation of the passenger room space is reduced or avoided, thereby reducing the risk of injury of the passengers.
However, when the collision strength exceeds the upper limit of the energy absorption value of the deformation zone at the rear part of the front part of the vehicle body, the passenger cabin is still in risk of extrusion deformation. In addition, the existing traffic accident scene has great risk of interlinking collision and vehicle fire, and passengers of the integral vehicle body are difficult to leave an accident area in time after the collision accident due to factors such as personnel injury or vehicle body deformation and the like, so that secondary injury is avoided.
The patent document with the publication number of CN101508275A discloses a collision-reducing, anti-drag and deformation safety car body, which consists of an air bag, an air charging and discharging device, a manual switch and a speed monitoring system, and is characterized in that: the air bags are inlaid in the metal plates of the head, the tail and the body and are connected with the inflation and deflation device. The speed monitoring system and the manual switch are connected with the air charging and discharging device, and the air charging device is automatically or manually started. After the air bag is inflated, the automobile body is deformed and is streamline. The technical solution disclosed in this patent document also fails to solve the above-described technical problems.
