A kind of device that slows down impact force
Technical field
The utility model relates to a kind of device that slows down impact force, particularly a kind of car and boat are with slowing down the device of impact force, for example the fender bar of the bumper/spoiler of vehicle or boats and ships also is applicable to the place that other need to prevent impact force, such as freeway guardrail, port and pier guardrail etc.
Background technology
Vehicle or boats and ships in use bump easily, often cause grave accident owing to the protective device outside hull or the car body arranges protection unit unreasonable or in the air when bumping, and cause casualties and property damage.
Chinese Automobile Industry ' Economic Operation bulletins in 2011 of the Ministry of Industry and Information Technology's issue show that 2011, China Auto Market was realized growing steadily, and the automobile volume of production and marketing is two to surpass 1,840 ten thousand, again refreshes global historical record.According to China Association for Automobile Manufacturers's statistics, China's accumulative total in 2011 is produced 1841.89 ten thousand in automobile, increases by 0.8% on a year-on-year basis, and 1850.51 ten thousand of selling automobiles increase by 2.5% on a year-on-year basis.Data show that 2011, after strictly forbidding drunk driving, automobile pollution reached 1.04 hundred million China, has 6.2 ten thousand people to be killed in an automobile accident.Learn in the national communications and transportation working conference in 2012 that 298 of Kuomintang-Communist generation ships that transport traffic accidents in 2011, dead missing 291 people search and rescue 2150 of ships in distress, personnel 18712 people that are rescued, Success in Salvage rate 96.7%.As can be seen from the above data, the incidence of accident is very frequently, and car and boat often because fender guard is incapable, happen occasionally so that the phenomenon of car crash appears in accident.Now the most general method is that lateral margin one circle at hull is provided with guard collar or guard is set around lateral border, then coat one deck rubber layer at guard, but the protective device that existing two kinds of methods adopt substantially all is that rubber or soft plastic are coated on the hull lateral border, can slow down to a certain extent the impact of collision during collision, but this degree of slowing down is lower, and the effect of playing is also very little.
The ZL01217833.0 Chinese utility model patent discloses a kind of safety collision damper for ship, and the cross section of this buffer body main body is respectively semicircle, annular arrangement, trapezoidal; In main body mounting hole is arranged, mounting hole runs through from upper surface to the lower surface of main body; End face in main body scribbles banded yellowish-white alternate refletorized paint, it is screwed on the hull, this safety collision damper for ship can only arrange at ad-hoc location, if this buffer body all is installed around the hull, and the speed of advance of cost height and obstruction hull.
Application number is that the Chinese invention patent application of CN93111409.8 discloses way to play for time and the device that a kind of name is called a kind of ship collision, it installs a kind of can being connected with the automatic opening-closing door on the hull around the hull, the flexible boats and ships buffer device for collision of scalable or translation-angle, this device can utilize hydraulic pressure, air pressure, single or the various ways such as spring and machinery combine and make, but this apparatus and method complicated operation, cost is higher, can slow down impulsive force in the situation about giving warning in advance, if but it does not have the effect that effect slows down impulsive force when running into paroxysmal collision.
GB99815571.3 Britain patent of invention discloses a kind of Collosion-resistant double-skin structure, such as double-deck ship sidepiece, comprises an outside coverboard and an inner coverboard.One group make and be arranged to by extensible material each other and by or up and down stacked passage be fixed to the inside face of structural outer coverboard by the end of their sidewalls, the base portion of each passage be connected to the inside configuration coverboard by a longeron that is basically perpendicular to described base portion at least or a structure being connected thereto on, the crash-resistant apparatus structure of this structure is complicated, and manufacturing time is normal, processing technology is complicated.
