Problems solved by technology

When an overlap collision of less than 25% occurs, it just avoids the energy-absorbing structure of the traditional vehicle longitudinal beam, and directly impacts the A-pillar and the passenger compartment of the vehicle, resulting in serious deformation of the passenger compartment, posing a major safety hazard

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] In related technologies, when an automobile collides, the combined structure of the anti-collision beam and the longitudinal beam absorbs the collision energy mainly through force deformation, so as to protect the occupants. A 25% overlapping rigid wall impact test at a speed of 64km / h is added to the IIHS regulations, also known as a small offset impact test.

Abstract

The present invention discloses an energy absorption structure and a vehicle with the same. The energy absorption structure comprises: a longitudinal beam extending in a front-rear direction; a crossbeam which extends in the left-right direction, wherein at least one part of the cross beam is located in front of the longitudinal beam; a first buffer piece which is connected between the longitudinal beam and the cross beam; and a second buffer piece which is connected between the longitudinal beam and the cross beam, and is suitable for providing lateral force for the longitudinal beam. According to the energy absorption structure of the embodiment of the invention, the second buffer piece is arranged and is suitable for providing lateral force for the longitudinal beam, so that when the cross beam is impacted, the cross beam can be driven by the second buffer piece to be laterally bent or deviated to absorb energy, and the energy absorption effect is good.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an energy-absorbing structure and a vehicle with it. Background technique [0002] In related technologies, when an automobile collides, the combined structure of the anti-collision beam and the longitudinal beam absorbs the collision energy mainly through force deformation, so as to protect the occupants. A 25% overlapping rigid wall impact test at a speed of 64km / h is added to the IIHS regulations, also known as a small offset impact test. When an overlap collision of less than 25% occurs, the energy-absorbing structure of the traditional vehicle longitudinal beam is just avoided, and the A-pillar of the vehicle and the passenger compartment are directly impacted, resulting in serious deformation of the passenger compartment, posing a major safety hazard. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art ...
