Abstract
The invention discloses a plate spring bumper which is mounted on an automobile for use. Thousands of miserable traffic collisions still happen, and a conventional bumper is difficult to play a security effect. The plate spring bumper performs shock absorption under the buffering action of a spring, and absorbs traffic collision energy by means of a rack and a top spring. The plate spring bumper is cheap in manufacturing cost, and easy to mount and use; and traffic collision energy is received and stored, so that the casualty rate of people can be reduced, and economic loss is greatly reduced.
Description
Technical field is contained on automobile and uses.
Background technology is collided thousands of, and horrible sight is grown wild, and existing bumper/spoiler difficulty plays the effect of insurance.
The buffer action damping of spring for summary of the invention, hospitalizes collision energy with tooth bar and top spring.
The specific embodiment is made a steel bar with spring steel, the length and width of this steel bar, thick X, Y, the Z of being made as respectively; The circle of formation that is connected together is touched in two of steel bar, this circle is pressed into a date core shaped shape, this fabrication is hereinafter to be referred as spring coil; At spring coil, be the waist both sides of above-mentioned date core shaped shape to boring two circular holes, with a screw, screw through two Kong Bingyong nuts, the axis of this screw must be by spring coil, divide equally up and down; Select an automobile, this automobile is hereinafter to be referred as car, the bumper/spoiler of car is pulled down, above-mentioned spring coil is placed in the middle, symmetrical, the parallel front end that is riveted on two crossbeams of car, during riveted joint, must guarantee that above-mentioned spring coil and car all keep level, the axis of above-mentioned screw is parallel with the extended line of car two crossbeams, wears screw cap one side towards the rear of car; Above-mentioned screw is replaced as to tooth bar, one end of tooth bar is fixed on the original screw hole in the inner side of spring coil with bulb and bulb jump ring, the tooth of tooth bar must be made " hangnail " shape, the flank of tooth is downward, the bill of " hangnail " points to the front lower place in car front, makes this tooth bar enter badly to go out by following rectangular opening fashion; Above-mentioned screw cap is replaced as top spring, and this top spring can withstand the above-mentioned tooth bar back side after installing, and when tooth bar is moved to car rear by following rectangular opening, has to into not drawing; Make to be applicable to another screw hole on above-mentioned spring coil into rectangular opening that above-mentioned tooth bar passes, four limits of this rectangular opening are all than 8 to 12 millimeters of cross section four limits of above-mentioned tooth bar maximum, length, while making tooth bar any direction change 30 degree angle all good by and the top spring of being replaced by above-mentioned screw cap withstand, because the function of above-mentioned " hangnail " can only be advanced to tailstock rear above-mentioned tooth bar, can not fall back; The fabrication and installation of tooth bar and top spring require: from car the place ahead, press spring coil, often by compressing into 2 centimeters, above-mentioned top spring, all tooth bar withstand can must not and be bounced back, until two medial surfaces of spring coil are fitted substantially; Unclamp above-mentioned top spring and tooth bar is upwards lifted, tooth bar can be retracted into rapidly original position; The quality of the value of above-mentioned X, Y, Z and the length of tooth bar and steel must be selected according to vehicle size, but must meet following requirement after selection fabrication and installation: loading onto the car of above-mentioned spring bumper/spoiler, when travelling by normal speed, knock after the firm metope in the place ahead, the distance between two longitudinal plane of symmetrys of spring coil inner side is not more than 2 centimeters, is not less than 1 centimeter, above-mentioned center refers to above-mentioned two 1/2nd places between " jujube point "; Unclamp above-mentioned top spring, lift tooth bar, spring coil energy return becomes original form; When actual product designs and produces can by one of lining in the middle of inner side before spring coil short, arch spring plate; " jujube point " shape at two is pressed into the shape of semicircle; Tooth bar and top spring are increased to two to three, make (bump against shucks flat).The front end of spring coil is decorated and made contour of the vehicle as before attractive in appearance.Above-mentioned making if with the throttle of car, brake control system interlock effect can be better.
Inexpensive, the good dress of beneficial effect making of the present invention, handy, because the energy of colliding is received and kept, so can reduce personnel's dead and wounded rate, has greatly reduced economic loss.
