Description

Technical Field

[0001] The invention relates to the technical field of vehicle frame structures, and in particular to a passenger car collision energy absorption safety vehicle frame structure. Background Art

[0002] Buses have a simple frame structure design and a large passenger capacity, so traffic accidents are extremely dangerous. When a bus is involved in a head-on collision, the force on the front area is concentrated, which often causes serious deformation of the front area while the middle and rear parts of the car are slightly damaged. Therefore, a new bus frame structure is needed, which introduces the energy absorption and buffering design concept in modern automobile design to reduce the impact of the collision on the front of the car.

[0003] For example, application number: CN202221229841.6 involves a collision energy absorption safety frame assembly, including a metal longitudinal beam and an intermediate cross beam, the metal longitudinal beam is installed and fixed on the outer sides of both ends of the intermediate cross beam, the outer ends of the metal longitudinal beam are provided with external fixing blocks, the front end of the metal longitudinal beam is provided with a front bent beam, the outer end of the front bent beam is provided with an outer ear block, and the inner side of the front bent beam is provided with a fixed sleeve arm rod. The new type is provided with an energy absorption limiter structure, which makes it easy to fix the energy absorption fixing ring, and the bottom panel of the energy absorption limiter is fixedly connected to the front bent beam by assembling screws, so that the bottom panel is easy to be stably installed and fixed, so that the limit block at the outer end of the bottom panel is easy to limit support, and the limit block is convenient for limiting sleeve energy absorption fixing ring fixation due to the bending ring limit groove on the inner side of the outer end, so that the limit block is effectively limited and fixed to avoid loose displacement of the energy absorption fixing ring.

[0004] However, there are some shortcomings in the current bus safety frame design. First, the front side of the car lacks an energy-absorbing and buffering structure. When hit, it can only rely on the resin front bumper for buffering. The buffering effect of the front bumper is limited. Once the front bumper fails to buffer, the front anti-collision beam will be directly hit, and the impact force will extend backward through the anti-collision beam, causing damage to the frame. Secondly, the anti-collision structure of the bus will collapse backward after being hit, and there is a risk of squeezing into the cab, thus posing a certain threat to the driver's life safety. Summary of the invention

[0005] In view of the above problems, one purpose of the present application is to remedy these shortcomings, and more specifically to provide a passenger car collision energy absorption safety frame structure, which can buffer in advance when the anti-collision beam is hit, reduce the force of direct impact on the anti-collision beam, and guide the collapse direction of the anti-collision structure when hit to prevent it from being squeezed into the cab.
