Abstract
The invention discloses a high-strength Pi-type automobile two-way buffer bumper. The high-strength Pi-type automobile two-way buffer bumper is located on a front case and a rear case of an automobile chassis and installed on a chassis frame. The high-strength Pi-type automobile two-way buffer bumper is composed of a safety collision avoidance assembly, a secondary buffer device and an elastic buffer assembly. When a front or back collision happens to an automobile, collision force can be effectively buffered, and thus the overall structure of the automobile and the personal safety can be protected. The high-strength Pi-type automobile two-way buffer bumper can be installed on the front case and the rear case and is only suitable for various types of automobiles with wheel-beam type axle-free frames. An elastic part special for collision avoidance is used, guide devices are arranged at the positions, at the front end and the rear end of an automobile body, of the chassis frame, and thus an obvious buffer and collision avoidance effect is achieved through two-way energy attenuation.
Description
Technical field
The invention belongs to automobile technical field, relate to a kind of car chassis safety collision-protection device, particularly a kind of high strength π type automobile round trip buffer bumper.
Background technology
Along with the growth in the living standard of the development people of society, auto age is stepped in the whole world, and it is greatly convenient that automobile brings to our life, becomes us and to go out at ordinary times the main vehicle.But increasing of automobile simultaneously also brings greatly dangerous hidden danger to us, motor traffic accidents and cause the number of personnel's casualties very many.Existing safety anti-collision device for automobile bumper/spoiler, many employings hollow tubular or Plastic Parts are made, and from the close together of vehicle head, when occurring to clash into, the buffer capacity of bumper/spoiler is very limited, potential energy converting and energy kinetic energy or other degradation of energies very little, therefore ensureing that the effect of secure context of automobile is not fully up to expectations.
Summary of the invention
The object of the present invention is to provide a kind of high strength π type automobile round trip buffer bumper; the present invention is round trip interval kinetic energy decay anticollision device; be arranged on the safety collision-protection device on car chassis; automobile occur front, clash into below time; can effective buffering percussive force, protection entire vehicle structure and personal safety.This device can be arranged on forward and backward two casees, and is only applicable to wheel beam type without the various vehicles in bridge vehicle frame.
The present invention is positioned at front case and the rear cabinet of car chassis, is arranged on chassis frame.Be made up of anticollision assembly, secondary buffer device and elastic buffer member.
Described anticollision assembly is made up of multiple crashproof special airbag elastic component, guide piece.Described crashproof special airbag elastic component adopts high-intensity high-tenacity elastomeric material to make, for anticollision customized design, very large impulsive force can be born, and the large compression ratio of multilayer Long Distances, interlayer fill gaps air, centre arranges pilot bar, when being subject to clashing into, crashproof special airbag elastic component is compressed along pilot bar, in air bag, gas is sharply increased by compressed pressure, go into huge degradation of energy effect, can absorb greatly clash into from potential energy, play buffering collision of closed, reduce the effect that car body damages and increase passenger safety factor.Described guide piece is arranged on car chassis vehicle frame, installation site is corresponding with each crashproof special airbag elastic component, with the pilot bar bearing fit of crashproof special airbag elastic component, when car body is subject to clashing into, pilot bar slides in guide piece, plays directional tagging to crashproof special airbag elastic component.
Described secondary buffer device is arranged on after elastic buffer member and also keeps certain distance with it, and be arranged on vehicle frame, secondary buffer device is made up of multiple anti-collision rubber block.When air bag elastic component is compressed to ultimate failure, elastic buffer member and anti-collision rubber block bump against, and play second time buffer action.
Described elastic buffer member is positioned at car chassis safety collision-protection device of the present invention foremost, become with cushion layer mounting frame by elastic cord breaker, described elastic cord breaker by elastomeric cushion material as the material such as polyurethane, rubber is made, can absorption portion energy when collision happens, play certain buffer action.Described cushion layer erecting frame uses high strength material to make, for installing elastic cord breaker and playing a supporting role.
Beneficial effect of the present invention:
The present invention utilizes crashproof dedicated elas-tic part, and on car body front end and car body rear end chassis frame, be provided with guide piece, two-way attenuation energy plays the effect of obvious cushion bumper simultaneously.
