Technical field
The utility model relates to a kind of vehicle bumper, relates in particular to a kind ofly can absorb when collision happens and relax impulsive force, thereby helps reducing the loss, protecting the buffering of personal safety to hit Federal bumper.
Background technology
Vehicle bumper is a kind of safety device that is fixed on position, various auto bodys front and back.Existing vehicle bumper is based on materials such as metal, glass-felt plastics, the vehicle bumper of metallic material is generally with the above steel plate punching press of the 3mm channel-section steel that takes the shape of the letter U, more than the vehicle bumper made of various materials flexible or broken when bumping, impact resistance is relatively poor, only can absorb and relax seldom a part of foreign impacts power, thereby to the damage of people's injury, vehicle or quite big to the damage rate of other object.By retrieval, the patented technology scheme that relates to Federal bumper is many, wherein application number is arranged is 96212587.3 elasticity safety device to the technical scheme that is close with this case, it is made up of a thick rubber strip of strong elasticity and a plurality of rigidity spring, one end of its spring embeds in the rubber strip, and the other end is by being bolted on the original bumper/spoiler of vehicle; Application number is 98227121.2 self-propelled vehicle flexible resilient bumper/spoiler for another example, and this scheme is that the outside face at rigid support is provided with the flexibility or the elastic buffer body of one deck at least, and they are an integral body.If technique scheme can become product and place in operation; when bumping, can absorb and relax the part impulsive force; but perfect inadequately because of its scheme still exists to absorb and to relax impulsive force limited, is difficult to reach protect personal safety to the full extent, reduce property damage.
Summary of the invention
The purpose of this utility model provides a kind of buffering that can absorb and relax greater impact power to hit Federal bumper at existing Federal bumper above shortcomings, protects personal safety to the full extent, reduces property damage.
The purpose of this utility model is achieved through the following technical solutions, and a kind of buffering is hit Federal bumper, comprises the supporter of rigid material, it is characterized in that the outside face of rigid support is provided with the flexible buffer body of parcel several sets of springs assembly set.
The flexible buffer body is made of through bonding horizontal involutory two parts, have in it some and horizontal involutory surface vertical to the cavity of inserting every group of spring assembly; The length of cavity is 1/2 of spring design height, and the spacing of adjacent cavity is 3-4cm; Also be provided with and cavity circular hole in the same way between several cavities and several cavities in the flexible buffer body, the diameter of circular hole is 1/2 of a cavity diameter, and circular hole and cavity are isometric; The flexible buffer body can be made by elastomeric material or plastic material; The flexible buffer external surface of rigid support external surface also can be provided with backplate, between rigid support and the flexible buffer body, or bonding between the backplate of rigid support and flexible buffer body and flexible buffer body and its outside face through lining cement; Spring assembly comprises the sheath that spring and two ends thereof are nested with; Spring can be nested with by two reverse big or small diameter springs of spiral to be formed, and inside and outside spring pressure equates.
The utility model is by being provided with the flexible buffer body of parcel spring assembly at the rigid support external surface; make and respectively organize spring and had globality; when collision happens; have High Performance absorb and cushion most of foreign impacts power, not only have rigidity, toughness, but also have elasticity; accomplish to protect personal safety to the full extent and reduce economic loss, the utility model is suitable for various types of automobile.
Description of drawings
Accompanying drawing 1 is that the utility model structure is launched scheme drawing;
Accompanying drawing 2 is that the utility model flexible buffer body structure launches scheme drawing;
In the accompanying drawing: the 1st, outer layer plate, the 2nd, flexible buffer body, the 3rd, inner layer steel plate, the 4th, spring, the 5th, sheath, the 6th, cavity, the 7th, lining, the 8th, pad, the 9th, nut, the 10th, dowel hole, the 11st, pipe link, the 12nd, circular hole.
The specific embodiment
The utility model adopts two block plates, two rubber bodies or two plastic bodies, two flexible buffer bodies 2 are sandwiched in the middle of two block plates after bonding, with lining cement steel plate 1,3 is connected with flexible buffer body 2, open a plurality of vertical round spring cavities 6 in the flexible buffer body 2, spring 4 assembly sets are put in the cavity 6, have the trepanning of pipe link 11 usefulness of passing flexible buffer body 2 simultaneously, be connected with car body with two pipe links 11.
Also can adopt a block plate, cancel outer backplate 1.Cavity 6 length are 1/2 of spring 4 design heights in the flexible buffer body 2, and the distance between adjacent cavity 6 and the cavity 6 is between 3-4cm, and the quantity of cavity 6 is determined according to the size of the effective working area of bumper/spoiler design-calculated.
The diameter of cavity 6 is determined according to spring 4 diameter.Between four adjacent cavities 6, have small sircle hole 12, the diameter of circular hole is 1/2 of cavity 6 diameters, the degree of depth of circular hole 12 is identical with the degree of depth of cavity 6, the setting of circular hole 12 is convenient under the impact that is subjected to ambient pressure, increase the extruding space, make spring 4 in cavity 6, do relative effective motion, can save raw MAT'L simultaneously, alleviate the weight of bumper/spoiler.Two flexible buffer body and function neoprene resin glues are bonding as lining cement, adopt the part of flexible buffer body 2 as bumper body, not only can absorb and buffering impact greatly by actv., also have the effect of stabilizing spring 4.Also can adopt simultaneously piecemeal to suppress flexible buffer body 2 in the bumper/spoiler of the required various style of various vehicles, the flexible buffer body of piecemeal is combined into wholely directly is connected with inner layer steel plate 3.
According to different automobile types, select for use the spring 4 of different pressures, differing heights, different-diameter to install, because spring 4 pressure vary in size, the design when producing of the diameter of spring 4, material, height is all different.Therefore, large, medium and small type vehicle is selected spring 4 pressure differences for use.Full size vehicle selects for use spring 4 pressure about 70kg, about the spring 4 pressure 50kg that medium sized vehicle is selected for use, about the spring 4 pressure 30kg that dilly is selected for use.Revolve about the cluster spring 4 that adopts two big little springs 4 to form must divide, the pressure of inside and outside spring equals the pressure of single spring, and the pressure ratio of inside and outside spring is 5: 5, and the pressure of interior spring and outer spring equates.The slightly larger in diameter of sheath 5 is in spring 4 port outside diameter, mounting spring 4 assembly sets in the cavity 6 in flexible buffer body 2, and absorption that can be a large amount of and buffering are extraneous than strong impact force.
When bumper/spoiler adopts two block plates, outermost layer 1mm backplate 1 welding of an end of pipe link 11 and bumper/spoiler.The other end of pipe link 11 passes the lining 7 with the car body welding, fixes with pad 8 and nut 9.Lining 7 is convenient to pipe link 11 can make fore and aft motion under the compression shock in the external world, the interior external diameter of lining 7 is determined according to the diameter of pipe link 11.Protect the rigid support of steel plate 3 as bumper/spoiler in adopting one, pipe link 11 can be made T-shaped, and the front end of T shape embeds in the flexible buffer body, and the other end is identical with the car body method of attachment.Above bonded assembly device can guarantee to absorb effectively normally and cushion bigger foreign impacts power under the bigger impulsive force situation in the external world.
