Embodiment Construction

[0031] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0032] This embodiment provides an automobile collision energy absorbing device, which is installed between the automobile front rail 2 and the automobile bumper 3, such as figure 1 As shown, installed on both sides of the front of the car, each energy absorbing device 4 has two energy absorbing pipes 6 with a certain included angle, corresponding to the U-shaped arms of the bumper 3 to ensure vertical installation with the bumper 3. If a driving car collides, the impact on the bumper 3 of the car is divided into two types, one is a positive impact, and the other is a side impact. When a positive impact occurs, the energy absorption of the forward installation Th...

Abstract

The invention relates to an energy absorption device for car crashes. The energy absorption device for car crashes comprises two energy absorption pipes (6). One end of each energy absorption pipe (6) is connected with a rear connection device (8); the two rear connection devices (8) are connected to a mounting base (9) through two connection pins (10), and the energy absorption pipes (6) are fixed to a car longitudinal beam (2) through the mounting base (9); the energy absorption pipes (6) can rotate around the connection pins (10) to make the two energy absorption pipes (6) to have an included angle; the other end of each energy absorption pipe (6) is connected with a front connection device (7), and the energy absorption pipes (6) are fixed to a car bumper (3) through the front connection devices (7); and triggering structures are arranged at the ends of the energy absorption pipes (6) connected with the front connection devices (7). The energy absorption device for car crashes can effectively absorb crash energy and reduce the impact, and has versatility between different models.

Description

Technical field [0001] The invention relates to the technical field of automobile safety protection, in particular to an automobile collision energy absorbing device. Background technique [0002] If a car crashes during driving, the collision energy is mainly absorbed by the energy absorbing device between the bumper and the front rail of the car, so as to reduce the speed of the car and protect the safety of the occupants. At present, most energy absorbing devices on automobiles use metal structures, that is, an energy absorbing structure made of thin-walled metal is installed between the front rail and the bumper of the automobile. The metal material is usually steel with good toughness. This structure will undergo greater plastic deformation when a car collides, thereby absorbing the impact energy of the collision. [0003] Metal energy absorbing devices are usually stamped and formed. Once the metal is pressed into shape, its energy absorbing characteristics are fixed, and it...
