Embodiment 2
[0040] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the locking mechanism includes friction plates, clamps and hydraulic cylinder 2, and hydraulic cylinder 2 is arranged on the vehicle body , the piston rod of the hydraulic cylinder 2 can drive the hoop to press the friction plate tightly, so that the inner longitudinal beam 2 and the outer longitudinal beam 1 are locked. The locking mechanism works stably and is not easily damaged.
Embodiment 3
[0042] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1 or Embodiment 2, the difference is that in this embodiment, a slideway is provided on the car body, and a slide rail is fixedly connected to the inner longitudinal beam 2 , the slide rail can slide along the slideway, so that the inner stringer 2 slides longitudinally relative to the outer stringer 1 .

The invention provides an elastic longitudinal beam and an automobile provided with the same and belongs to the technical field of automobiles. The problem that the length of the existing longitudinal beam of the automobile can not be changed along with the change of the automobile speed is solved. The elastic longitudinal beam comprises an outer longitudinal beam and an inner longitudinal beam, wherein the outer longitudinal beam is fixedly connected to an automobile body; the inner longitudinal beam is connected with the outer longitudinal beam; a driving mechanism and a locking mechanism are arranged between the inner longitudinal beam and the outer longitudinal beam; the driving mechanism can cause the inner longitudinal beam to longitudinally slide along the outer longitudinal beam; the locking mechanism can cause the inner longitudinal beam to be fixed relative to the outer longitudinal beam; and the automobile body is also provided with a control circuit respectively connected with the driving mechanism and the locking mechanism. The automobile provided with the elastic longitudinal beam comprises elastic longitudinal beams arranged on two sides of the automobile body, the front end of the inner longitudinal beam is provided with an anticollision beam, and an energy adsorption box is arranged between the anticollision beam and the automobile body. The anticollision capability of the automobile at a high driving speed can be improved, and the throughput capacity of the automobile during driving at a low speed can be improved.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile, in particular to a telescopic longitudinal beam and an automobile provided with the telescopic longitudinal beam. Background technique [0002] With the development of society and the improvement of living standards, people have higher and higher requirements for the safety of automobiles. When a car collides, the car body bears a huge impact force, causing damage to the car body and endangering the personal safety of passengers. The size of the crushable area of the car has a great influence on the safety performance of the vehicle. The crushable area can absorb the impact force, reduce the deformation of the cab, reduce the damage to passengers, and improve the safety performance of the car. [0003] In the prior art, bumpers are usually installed at the front and rear ends of the vehicle body to increase the crushing area of the vehicle body. In order to...
