Abstract

The utility model belongs to a safety maintaining component of automobile, and particularly to a cylinder type safety impact buffer unit which comprises a connection plate (6), connection holes (6-1) and a housing (1). An impact plate (1-1) is provided at the front part of the housing (1), and a bottom plate (1-2) is provided at the rear part. A vibration reduction hole (1-3) is provided on the impact plate (1-1). A plurality of cylinders (3) are fixed among the impact plate (1-1) and the bottom plate (1-2) in the housing through cylinder fixing screws (2). A plurality of dampers (5) are fixed through damping set screws (4). A safety box (3-1) which is filled with pyroxylin and explosive is provided in each cylinder (3). The inner wall of the housing of each damper (5) is provided with inner ratchets (5-1). An inner rod of each damper (5) is provided with outer ratchets (5-2). The inner ratchets (5-1) are engaged with the outer ratchets (5-2). The instantaneous time of impact can be prolonged and the impact pressure can be alleviated for performing a function of impact buffering.

Description

Air-cylinder type safety impact attenuation device

Technical field

The utility model belongs to automobile security parts, particularly a kind of air-cylinder type safety impact attenuation device.

Background technology

Development along with auto trade, demand as the bumper/spoiler of automobile security parts is also increasing, requirement to its safety factor is also more and more higher, when though the bumper/spoiler of existing automobile can or knock into the back at bump, played the effect that slows down impulsive force to a certain extent, it is very limited that but existing bumper/spoiler bears pressure, very easily is out of shape when bump, and the security effect that is play is extremely limited.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of simple in structure, air-cylinder type safety impact attenuation device that the security performance is good is provided.

The technical scheme that the utility model technical solution problem adopts is: air-cylinder type safety impact attenuation device comprises connecting panel, connecting bore, housing, be characterized in establishing crash panel in the housing front, base plate is established in the back, on crash panel, establish shock relieve vent, fix a plurality of cylinders with the cylinder check screw between crash panel inside housing and the base plate, with the fixing a plurality of dampers of damping check screw, establish a safety box that guncotton and explosive are housed in the cylinder the inside, on the inwall of damper shell, be provided with interior ratchet, bar is provided with outer ratchet in the damper, and interior ratchet is connected with outer ratchet engagement.

The beneficial effects of the utility model are: air-cylinder type safety impact attenuation device can prolong bump time moment, and relieving impact pressure plays impact buffer function, and injury of human is dropped to minimum level.

Among the figure, the 1-housing; The 1-1-crash panel; The 1-2-base plate; The 1-3-shock relieve vent; 2-cylinder check screw; The 3-cylinder; The 3-1-safety box; 4-damping check screw; The 5-damper; Ratchet in the 5-1-; The outer ratchet of 5-2-; The 6-connecting panel; The 6-1-connecting bore;

The specific embodiment

Embodiment, with reference to accompanying drawing 1～4, air-cylinder type safety impact attenuation device is provided with crash panel 1-1 in housing 1 front, the back is provided with base plate 1-2, on crash panel 1-1, be provided with shock relieve vent 1-3, be respectively equipped with a connecting panel 6 in the both sides of base plate 1-2, be respectively equipped with a connecting bore 6-1 on the connecting panel 6.Fix five cylinders 3 with cylinder check screw 2 between the crash panel 1-1 of housing 1 the inside and base plate 1-2, damping check screw 4 is fixed two dampers 5.Establish a safety box 3-1 that guncotton and explosive are housed in cylinder 3 the insides, ratchet 5-1 on the inwall of damper 5 shells, being provided with, bar is provided with outer ratchet 5-2 in the damper 5, and the outer ratchet 5-2 of the interior bar of ratchet 5-1 and damper is connected with a joggle in the damper shell.

The principle of work of air-cylinder type safety impact attenuation device is: air-cylinder type safety impact attenuation device protrudes the position by the front that the connecting bore 6-1 on the connecting panel 6 is installed in automobile, when automobile low speed is advanced bump, crash panel 1-1 distortion is less, can not cause that safety box 3-1 breakage makes explosive initiation, when middling speed and high-speed travel bump, crash panel 1-1 distortion is bigger, crash panel 1-1 passes to cylinder 3 and damper 5 with the impulsive force of bump, the piston rod of cylinder 3 is with the air compression in the cylinder 3, increased pressure, safety box 3-1 is broken, and cylinder 3 interior temperature build-ups ignite guncotton and cause explosive charge simultaneously, realize collision buffering, and the interior ratchet 5-1 of damper 5 can advance and can not move back with outer ratchet 5-2 engagement, can not produce bounce-back behind the bump, make the damage of human body drop to minimum level.

Claims

1. air-cylinder type safety impact attenuation device, comprise connecting panel (6), connecting bore (6-1), housing (1), it is characterized in that establishing crash panel (1-1) in housing (1) front, base plate (1-2) is established in the back, on crash panel (1-1), establish shock relieve vent (1-3), fix a plurality of cylinders (3) with cylinder check screw (2) between crash panel (1-1) inside housing (1) and the base plate (1-2), with the fixing a plurality of dampers (5) of damping check screw (4), establish a safety box (3-1) that guncotton and explosive are housed in cylinder (3) the inside, on the inwall of damper (5) shell, be provided with interior ratchet (5-1), the interior bar of damper (5) is provided with outer ratchet (5-2), and interior ratchet (5-1) is connected with a joggle with outer ratchet (5-2).
