Abstract
The utility model relates to an automobile impact protector belongs to the vehicle technology field, the device includes bellows and straight tube two parts, be the integral type structure of a whole (monoblock material die-casting forms) each other, intraductal all encapsulates liquid, the straight tube rises and is equipped with the overflow hole, the rupture disk is equipped with on the hole, when the vehicle that traveles at a high speed takes place frontal collision, the impact makes the bellows produce compression deformation, it makes intraductal liquid produce huge pressure again to warp, and finally break away the rupture disk, the striking can change into the liquid compression energy thereupon, form the high-speed blowout of liquid stream and release, thereby play the buffering guard action. The device can be directly welded or packaged on a vehicle chassis, the ground clearance of the chassis and the dead weight of the vehicle cannot be influenced by the device, and the device is suitable for medium and small vehicle types.
Description
Technical field
The utility model relates to a kind of safety device of traveling vehicle, and especially a kind of automobile impacting fender guard belongs to the traveling vehicle technical field.
Background technology
After the automobile invention, the human shade of not breaking away from car accident all the time is though invented car belt, protective equipments such as safety air bag, but these facilities or cost costliness need spend thousands of units as air bag, and protection effect is not very good.The protection effect of safety strap is better than air bag, but it has influenced occupant's ride quality, and quite a few occupant does not wear safety strap under steam.So, safety strap does not have due protective effect.All kinds of reason makes the result of use of safety strap and safety air bag beat certain discount.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the utility model proposes a kind of with low costly, structure is light, is convenient to install, and does not influence ride quality, not the safety device of image vehicle body structure and in-use performance.
The utility model is based on the hydraulic cushion principle: the technical scheme of taking is that whole automobile impacting energy-absorbing buffering device is made up of bellows and straight tube two large divisions.The two large divisions becomes one by die-casting process, equal enclosing liquid in the pipe.Straight tube is provided with overflow weir, and rupture disk is installed on the hole.After vehicle has been installed device of the present utility model; in when, in running at high speed head-on crash taking place; Impact energy impels bellows generation compressive deformation; distortion impels the bellows and the straight tube in-to-in liquid that communicate all to produce immense pressure again; and finally wash rupture disk open; bump can change liquid compression thereupon into and can form high pressure liquid stream ejection and release energy, thereby plays buffer protection function.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of an embodiment of the utility model.
1. bellowss among the figure. 2. straight tube. 3. overflow weir.
The specific embodiment
The automobile impacting energy-absorbing buffering device of present embodiment mainly contains bellows 1, straight tube 2, and overflow weir 3 is formed.Bellows 1 is vertical with automobile front beam to be connected, and straight tube 2 is connected with the automobile front side member, and the mode of being connected adopts welding or screw all can.
In when, in the vehicle that present embodiment has been installed is being run at high speed head-on crash taking place; the Impact energy that bumper/spoiler bears passes to the bellows 1 that is connected with it immediately; make bellows 1 that compressive deformation take place; compressive deformation makes the bellows that communicates 1 and liquid in the straight tube 2 all produce immense pressure again; finally wash the rupture disk of installing on the straight tube overflow weir 3 open; highly pressurised liquid sprays from overflow weir 3 high speeds, thereby releases energy, and vehicle and occupant are all played the safety guard-safeguard effect.
Claims (2)
1. an automobile impacting energy-absorbing buffering device comprises bellows and straight tube two major parts, it is characterized in that: bellows is an integral body that links to each other and communicate with straight tube, equal enclosing liquid in the pipe.
2. according to the described automobile impacting energy-absorbing buffering of claim 1 device, it is characterized in that: offer overflow weir on the straight tube, rupture disk is installed on the hole.
