Abstract
The utility model relates to a safety bumper of a motor vehicle, which can achieve that the damage of impact force to vehicles, persons and goods is first-rate reduced through ternary buffering and absorption of the impact force when the bumper is impacted. The safety bumper is composed of a bumper part 1, a rubber spring buffering part 2, a shaft lever 3, a spring-nylon buffer case 4 and a lock-nut component 5. The utility model has the advantages of simple structure, high safety and large development potential, and is suitable for various motor vehicles.
Description
The utility model relates to a kind of bumper for automotive vehicle, can reduce the bumper for automotive vehicle of impulsive force to car, people, thing damage when particularly a speciogenesis is collided.
Present bumper for automotive vehicle does not have pooling feature, thus when collision can produce powerful the impact to car body, cause the damage of vehicle-mounted people, thing and car body easily, even personnel die.Existing several designs that the bumper/spoiler of pooling feature is arranged only depend on spring to reach the buffering purpose, in case length of spring compressed reaches capacity, the impulsive force that car body is produced still is no small, and can not link with other protection mechanism.
The purpose of this utility model is to provide a kind of when vehicle hits on bumper/spoiler, can pass through multi-buffer, reduces the damage of impulsive force to vehicle, vehicle-mounted people and thing, can drive the self-propelled vehicle safety bumper of other collision fender guard simultaneously again.
The utility model is achieved in that the bumper/spoiler of self-propelled vehicle is to be connected with under-carriage by the mechanism with triple buffer effect, and this mechanism can link, and other reduces the protective device of impulsive force (for example brake, stop working).The utility model has axostylus axostyle, spring-nylon dash pot and the black nut assembly of annular boss to constitute in the middle of by bumper/spoiler part, rubber spring buffer portion, two ends thread rod being arranged.Solid welding has female sleeve on the bumper/spoiler of bumper/spoiler part, and preceding axostylus axostyle front end thread rod screws in the back and lives with the black nut locking, finishes connecting of bumper/spoiler and buffer gear.Be with the rubber spring buffer portion that constitutes by rubber spring, rubber spring seat, band panel nut, black nut on the preceding axostylus axostyle.Distance between band platen nut scalable rubber spring seat and spring-nylon dash pot, to guarantee compression spring in rubber spring and the spring-nylon dash pot, the nylon spring perch has collaborative buffer action.Spring-nylon dash pot is made of sleeve, baffle ring, nylon spring perch, nylon annular boss-spring perch, compression spring.The baffle ring solid welding at the bottom of sleeve, built-in nylon spring perch; Compression spring is located on the nylon spring perch after filling in the sleeve, the spring perch of nylon annular boss-spring perch is withheld on compression spring again; The back axostylus axostyle is passed nylon annular boss-spring perch, behind spring, the nylon spring perch, annular boss is located in the annular boss seat of nylon annular boss-spring perch; The rear end thread rod that will pass the back axostylus axostyle of spring-nylon dash pot then screws on the band panel nut, mixes up the back and pins with black nut.Nylon annular boss-spring perch slides in sleeve along with the flexible of compression spring.Back axostylus axostyle is also along with stretching of compression spring slided in the nylon spring perch.Annular boss-spring perch, the spring perch of metallo-sleeve, back axostylus axostyle and nylon are done the slide relative effect and can be reduced friction and noise.Nylon annular boss-spring perch and nylon spring perch since be accurate rigidity and have an ability that certain elastic deformation absorbs impulsive force, institute is so that the utility model has been Duoed a function that heavily reduces impulsive force than the bumper/spoiler of dependence spring buffer merely.Spring-nylon dash pot is fixed on the vehicle undercarriage front portion.Rear end thread rod sponson can link with other emergency device.Like this, the impulsive force that car body, vehicle-mounted people and thing are subjected to just reduces widely even avoids, and has improved the safety of vehicle.
Below in conjunction with accompanying drawing the utility model is described:
1, is the bumper/spoiler part, constitutes by bumper/spoiler 21, solid welding female sleeve 20, the black nut 2 on bumper/spoiler 21; The 4th, the rubber spring buffer portion, by black nut 2, the band pressing plate 17 nut 3, rubber spring seat 5 and rubber spring 18 constitute; The 6th, axostylus axostyle is divided into preceding axostylus axostyle 7 and back axostylus axostyle 8 by the annular boss 11 at middle part, and the front end of preceding axostylus axostyle 7 is front end thread rods 19, and the end of back axostylus axostyle 8 is rear end thread rods 16; Spring-nylon dash pot 8 is made of sleeve 9, nylon annular boss-spring perch 10, compression spring 13, nylon spring perch 14, baffle ring 15; Black nut assembly 22 is made of the nut 3 and the black nut 2 of band pressing plate 17.Solid welding has female sleeve 20 on the safety lever 21, and the front end thread rod of preceding axostylus axostyle 7 19 screws in wherein the back and lives with black nut 2 lockings, and safety lever 21 connects with buffer gear to be finished.Be with rubber spring buffer portion 4 on the preceding axostylus axostyle 7, the rubber spring seat 5 of seat rubber spring 18 and the distance L 1 between spring-nylon dash pot 8 in band platen nut 3 scalable, platen 17 is pressed on the rubber spring 18, compression stroke L2 than spring 13 is short, mix up the back with black nut 2 lockings, so that rubber spring 18 can play the partial buffer effect.Baffle ring 15 solid weldings are in the bottom of sleeve 9, built-in nylon spring perch 14; Compression spring 13 is located on the nylon spring perch 14 after sleeve 9 front ends are filled in, and withholds the compression spring seat 23 of nylon annular boss-spring perch 10 on compression spring 13 again and fills in sleeve 9; Back axostylus axostyle 12 is passed nylon annular boss-spring perch 10, compression spring 13, nylon spring perch 14, annular boss 11 is fallen in the annular boss seat 24 of nylon annular boss-spring perch 10; The rear end thread rod 16 that passes the back axostylus axostyle 12 behind the baffle ring 15 is screwed on band panel nut 3, be adjusted to L2 and L1 and satisfy aforementioned requirements usefulness black nut 2 lockings afterwards.Nylon annular boss-spring perch 10 slides in sleeve 9 along with the flexible of compression spring 13.Back axostylus axostyle 12 also slides in sleeve 9 along with the flexible of compression spring 13.The metal sleeve 9 of nylon-spring buffer tube 8 is fixed on the vehicle undercarriage front end.Rear end thread rod 16 can link to improve the whole protecting against shock ability of vehicle with other emergency device.When self-propelled vehicle hit on bumper/spoiler 21, the impulsive force that bumper/spoiler 1 is subjected to was passed on the compression spring 13 by axostylus axostyle 6, and compression spring 13 absorbs most of absorbed-in-fracture energy.When compression spring will compress when finishing, rubber spring seat 5 is crushed on spring-nylon dash pot 8, and rubber spring 18 is compressed and absorbs certain absorbed-in-fracture energy.Elastic deformation takes place and absorbs certain absorbed-in-fracture energy with nylon annular boss-spring perch 10 in nylon spring perch 14 all the time.
The utility model is simple in structure, impact resistance is strong, safety can by big by property height, potentiality to be exploited, be applicable to multiple power actuated vehicle.
