Description
Technical field
The utility model relates to automobile case field, particularly a kind of Federal bumper.
Background technology
Along with the development of society, the raising of people's living standard, the vehicle that automobile has become people's go off daily comparatively common.
Then, along with increasing of automobile quantity, road conditions are day by day complicated, and traffic accident takes place frequently, and serious threat is to the safety of life and property of people, and people are also more and more higher to the requirement of Federal bumper thereupon.
Traditional bumper/spoiler is mainly based on single layer structure, as long as there is slight collision, bumper/spoiler will be impaired, ability to bear for impulsive force is smaller, particularly when non-accident, reel for some, bumper/spoiler all can be subject to larger damage, virtually adds the maintenance cost of automobile.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of structure simple, and the Federal bumper that anti-collision effect is good.
The utility model solves the technical scheme that its technical matters adopts: a kind of Federal bumper, comprise the mobile jib and secondary bar that be arranged in parallel, some Buffer Units are evenly provided with between described mobile jib and secondary bar, described Buffer Unit comprises the first flange, first sleeve, second sleeve, second flange and spring, described first flange is fixed on the first sleeve upper end, described first sleeve lower end is stretched in the second sleeve by the second sleeve upper end, described second flange is fixed on the second sleeve lower end, described spring is arranged in the first sleeve and the second sleeve, described both ends of the spring is fixedly connected with secondary bar with mobile jib respectively, described spring is in compressive state.
In order to increase the stability of structure, reduce bumper/spoiler and rock, the external diameter of described first sleeve and second overlaps
The internal diameter coupling of cylinder.
In order to increase the fastness of connection, described secondary bar is provided with some tapped bore, and secondary bar is bolted.
In order to prevent the first sleeve movable in the second sleeve, outside described first sleeve, lower end is provided with and determines
Position ring, described second sleeve inner top side is provided with annular positioning groove, and described steady ring mates with positioning groove.
Conveniently dismounting and maintenance, described first flange and the second flange two ends all offer tapped bore, and the first flange and the second flange are separately fixed on mobile jib and secondary bar by bolt.
The beneficial effects of the utility model are: this Federal bumper, by setting up Buffer Unit between mobile jib and secondary bar, substantially reduces the impulsive force being delivered to secondary bar from mobile jib, reduces the extent of damage of bumper/spoiler.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model Federal bumper;
Fig. 2 is the structural representation of the Buffer Unit of the utility model Federal bumper;
In figure: 1. mobile jib, 2. secondary bar, 3. Buffer Unit, 31. first flanges, 32. second flanges, 33. first sleeves, 34. second sleeves, 35. springs, 36. steady rings.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of Federal bumper, comprise the mobile jib 1 and secondary bar 2 that be arranged in parallel, some Buffer Units 3 are evenly provided with between described mobile jib 1 and secondary bar 2, described Buffer Unit 3 comprises the first flange 31, first sleeve 33, second sleeve 34, second flange 32 and spring 35, described first flange 31 is fixed on the first sleeve 33 upper end, described first sleeve 33 lower end is stretched in the second sleeve 34 by the second sleeve 34 upper end, described second flange 32 is fixed on the second sleeve 34 lower end, described spring 35 is arranged in the first sleeve 31 and the second sleeve 32, described spring 35 two ends determine to be connected with mobile jib 1 and secondary bar solid 2 respectively, described spring 35 is in compressive state.
In order to increase the stability of structure, reducing bumper/spoiler and rocking, the external diameter and second of described first sleeve 33
The internal diameter coupling of sleeve 34.
In order to increase the fastness of connection, described secondary bar 2 is provided with some tapped bore, and secondary bar 2 passes through bolt
Fixing.
In order to prevent the first sleeve 33 movable in the second sleeve 34, under outside described first sleeve 33
End is provided with steady ring 36, and described second sleeve 34 inner top side is provided with annular positioning groove, and described steady ring 36 mates with positioning groove.
Conveniently dismounting and maintenance, described first flange 31 and the second flange 32 two ends all offer tapped bore, and the first flange 1 and the second flange 32 are separately fixed on mobile jib 1 and secondary bar 2 by bolt.
Automobile jolts owing to can produce in traveling process, so be easy between the first sleeve 33 and the second sleeve 34 produce change in displacement, bumper/spoiler entirety is rocked, thus affect the stability of whole bumper, and after setting up steady ring 36 and positioning groove, just can make to keep geo-stationary between the first sleeve 33 and the second sleeve 34, reduce to rock, increase service life.
When mobile jib 1 is subject to external impacts, if external force is smaller, then mobile jib 1 self just can digest this impulsive force, if external force is larger, then mobile jib 1 will produce a larger pressure to the first flange 31, synchronous, first flange 31 is oppressed the first sleeve 33 and is moved towards secondary bar 2 direction, thus steady ring 36 is skidded off from positioning groove, along with the first sleeve 33 is close to secondary bar 2 gradually, the amount of compression of spring 35 is increasing, and the elastic force that spring 35 is produced is increasing, then increasing to the reaction thrust of mobile jib 1, thus play the effect of buffering.
Compared with prior art, this Federal bumper, by setting up Buffer Unit 3 between mobile jib and secondary bar, substantially reduces the impulsive force being delivered to secondary bar 2 from mobile jib 1, reduces the extent of damage of bumper/spoiler.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
