Abstract
The invention provides a tow-hook fixed structure which comprises a protruded part, an elastic component and a through hole, wherein the protruded part is radially protruded from an axle body at the front end of a tow hook, and the through hole is formed on a bumper beam; one end of the elastic component is connected with a carriage body or the axle body of the tow hook; the diameter of the through hole is less than the sum of the diameter of the axle body of the tow hook and the height of the protruded part radially protruded from the axle body of the tow hook and greater than the diameter of the axle body of the tow hook; and the circumference of the through hole is provided with a gap through which the protruded part passes. When the tow-hook fixed structure is installed, the tow hook can clamp the bumper beam just by directing the protruded part on the axle body of the tow hook against the gap of the through hole of the bumper beam and inserting the tow hook into the gap, rotating the two hook so as to misplace the protruded part and the gap, and then using the pretightening force of the elastic component to prevent the tow hook from rotating; and when the tow-hook fixed structure is disassembled, the tow hook can be pulled out from the gap just by pressing the tow hook inwards, and then rotating the tow hook so as to direct the protruded part of the tow hook against the gap of the through hole of the bumper beam. Compared with the traditional tow-hook fixed structure, the rotary fixing mode adopted by the tow-hook fixed structure provided by the invention is more time-saving and convenient.
Description
Technical field
The present invention relates to the automotive body structure technical field, be specifically related to a kind of car puller hook fixed sturcture.
Background technology
For motor space and consideration attractive in appearance, car puller hook adopts detachable more.Traditional car puller hook is mostly by being threaded on the motor insurance crossbeam.When needing, protect little blanking cover before and after opening, screw on car puller hook; Screw off car puller hook when not using, protect little blanking cover before and after refilling.This connection mode dismounting trouble, waste time and energy and also efficient low.
Summary of the invention
The objective of the invention is to propose a kind of dismounting car puller hook fixed sturcture easily that saves time.
Car puller hook fixed sturcture of the present invention, key is to comprise the through hole of offering on protuberance, elastomeric element and the insurance crossbeam of the axle body upper edge radially outwardly projecting of car puller hook front end, one end of described elastomeric element links to each other with the axle body of vehicle body or car puller hook, the diameter of described through hole less than the diameter of car puller hook axle body and described protuberance along the height sum of car puller hook axle body radially outwardly projecting and greater than the diameter of car puller hook axle body, the circumference of through hole is provided with the breach that passes for described protuberance.
When the present invention installs, pull down the little blanking cover that covers at the through hole back-end of insurance crossbeam, protuberance on car puller hook axle body and the axle body is aimed at the through hole of insurance crossbeam, then car puller hook being inserted inwards makes elastomeric element produce deformation, pass through hole up to car puller hook axle body protuberance, the car puller hook rotation is made the protuberance and the dislocation of the breach on the through hole circumference of car puller hook axle body, car puller hook just can block the insurance crossbeam by the protuberance on its axle body like this, utilizes the predetermincd tension of elastomeric element to prevent its rotation again; When not needing to use car puller hook, only need car puller hook is pushed inward, rotate car puller hook then and make the protuberance on its axle body aim at the breach that insures on the crossbeam through hole circumference, again car puller hook is extracted, load onto little blanking cover at last and get final product, convenient and simple.
Described elastomeric element is that described baffle plate is over against described through hole by spring and the fixing baffle plate of vehicle body.The effect of elastomeric element is to provide predetermincd tension to prevent its rotation to car puller hook, and its structure can be a spring that links to each other with the axle body of car puller hook; Also can be by spring and the fixing baffle plate of vehicle body, baffle plate be over against insurance crossbeam through hole, and spring is difficult for rocking like this, makes structure more stable.
Described protuberance has a plurality of and rectangular distribution on the axle body of car puller hook.The protuberance effect is to make car puller hook block the insurance crossbeam, thus preferably have a plurality of and along car puller hook axle body rectangular distribution so that stressed evenly, structure is firm.
Being positioned near the end face of through hole front opening on the aft end face of described protuberance and the described insurance crossbeam is rough surface.Only rely on initial tension of spring to prevent that the car puller hook rotation is too high to the performance requriements of spring, and not enough insurance, car puller hook still can rotate sometimes.Can be arranged to rough surface this moment with near the end face that is positioned on the aft end face of protuberance and the insurance crossbeam through hole front opening, protuberance blocks the contact surface that insures crossbeam and will produce bigger static friction force under the pressure effect of spring like this, prevents that further car puller hook from rotating.
The place, aperture of the through hole front end of described insurance crossbeam has the groove adaptive with the protuberance of described car puller hook, the gap position dislocation of described groove location and through hole.At only relying on initial tension of spring to be not enough to guarantee the problem that prevents the car puller hook rotation, can also can pin the groove of the protuberance of car puller hook axle body in place, the aperture processing of the through hole front end that insures crossbeam, so just can guarantee that car puller hook can not rotate, guarantee structural stability.
Described protuberance is for radially passing and protrude in the bearing pin of car puller hook axle body.The present invention can reequip on the conventional trailer hook, only a bearing pin that radially passes the car puller hook axle body need be set at the front end of car puller hook axle body, the length of bearing pin is greater than the diameter of car puller hook axle body, and then the bearing pin two ends that protrude in the car puller hook axle body just constitute the protuberance that blocks the insurance crossbeam.
Described protuberance is several projections that weld on the axle body of car puller hook, and the rear end of described projection is in same plane.The structure of protuberance can also be several projections that are welded on the car puller hook axle body, and the rear end of these projections should be in same plane, to play the effect of blocking the insurance crossbeam.
Described projection is more than three.Since stressed bigger during car puller hook work, so blocking the structure of insurance crossbeam, projection should guarantee its stability, so projection is at least more than three.
Car puller hook of the present invention, only need insert inward during installation with the breach on the aligning of the protuberance on the car puller hook axle body insurance crossbeam through hole circumference and with car puller hook, then car puller hook is rotated so that its protuberance and the breach dislocation of insuring on the crossbeam through hole circumference, utilize the predetermincd tension of elastomeric element just can prevent the car puller hook rotation, car puller hook just can utilize the protuberance on its axle body to block the insurance crossbeam like this; During dismounting, only car puller hook need be pushed inward, car puller hook be rotated so that its protuberance is aimed at the breach on the insurance crossbeam through hole circumference again, just car puller hook can be extracted, the fixed form of comparing traditional car puller hook rotation more saves time conveniently.
