Description
Technical field
In traffic accident generation personal security protection field, adopt safety strap and safety air bag to avoid personnel to collide with car body is powerful in the traffic accident at present.
Background technology
Safety strap avoids human body to clash into car body down because of the force of inertia effect in the traffic accident.Safety air bag then increases cushion layer at human body between car body before collision takes place, reduce impact force.When but most of traffic accidents took place, the previous of car body was expressed to the back by plastic deformation.Human body is stuck between car body and the seat.Cause the human injury, it is dead that serious personnel are stuck or all rescue measures proved ineffectual.
Summary of the invention
The purpose of this invention is to provide a kind of position that when traffic accident takes place, makes the automobile front-row seat move to not dangerous second series seat personnel backward.The possibility thereby the reduction personnel are stuck.The minimizing personnel are blocked the extent of injury of wound.And provide solution because of operator's saddle by after move the device of the protection system that self-actuating brake and the automatic power of the problem of generation stop working.
This fender guard moves system, autobrake system, automatic power shutdown systems, control circuit system, collision degree detecting system and connecting wire after by the automobile front-row seat and forms.It is characterized in that control circuit system moves system, autobrake system, automatic power shutdown systems and collision degree detecting system electronic control is connected respectively with behind the automobile front-row seat through connecting wire.
Move behind the automobile front-row seat system by inertia kinetic energy weight block (1), propulsive mechanism (2), buffering energy-absorbing mechanism (3), guide rail (4), break-in speed-changing mechanism (rope 5 and rotary pulley 6), can after move seat (7), seat slide (8), band groove and decide part (J), chassis connecting element (G1) and vehicle frame connecting element (G2) and form.It is characterized in that on the guide rail that is fixed on chassis connecting element (G1) (4), assembling successively buffering energy-absorbing mechanism (3), inertia kinetic energy weight block (1) and propulsive mechanism (2); Leave miles of relative movement between buffering energy-absorbing mechanism (3) and the inertia kinetic energy weight block (1), inertia kinetic energy weight block (1) and propulsive mechanism (2) abut against together.Inertia kinetic energy weight block (1) is connected with an end of the rope (5) of break-in speed-changing mechanism.Rope (5) other end through rotary pulley (6) with can after move seat (7) and be connected.Can after move seat (7) and be installed on the seat slide (8) that is fixed on vehicle frame connecting element (G2).Inertia kinetic energy weight block (1) and can after move and have electromagnetic control lock (1S and 7S) in the seat (7).Dead bolt in the electromagnetic control lock (1S and 7S) is stuck in the band groove to be decided in the groove of part (J).
Inertia kinetic energy weight block (1) is had the cuboid of guide rail and electromagnetic control lock (1S) assembly opening by heavy material (like cast iron) processing.
Propulsive mechanism (2) is to have the pressure spring or the multistage gaseous tension post that have compressed to constitute.Multistage gaseous tension post is assembled by one-level gaseous tension post (21), secondary gas pressure column (22), three grades of gaseous tension posts (23), round section joint ring (24) and high pressure gas input interface (25).Assembly method: the cavity part (232) of three grades of gaseous tension posts (23) is through round section joint ring (24) sealing and guide rail (4) assembling.The housing parts (231) of three grades of gaseous tension posts (23) is through cavity part (222) assembling of round section joint ring (24) sealing with secondary gas pressure column (22).The housing parts (221) of secondary gas pressure column (22) is through cavity part (212) assembling of round section joint ring (24) sealing with one-level gaseous tension post (21).One-level gaseous tension post (21) housing parts (211) and high pressure gas input interface (25) housing (251) close fit together.The pore (252) of cavity part (212), (222), (232) and the high pressure gas input interface (25) of one, two, three gaseous tension post keeps air to be connected.
Buffering energy-absorbing mechanism (3) is made up of pressure spring of unfolding or shock-absorbing hydraulic column.
Can after to move seat (7) be that existing automobile front-row seat (73) is installed on the movable stand (72).Wherein movable stand (72) is become to have the capable cuboid of support of guide rail (4) and electromagnetic control lock (73) assembly opening by metal work.
