Abstract
The utility model discloses a fixed bracket structure for a passenger side air bag impact test, which comprises support plates that are combined to form a support frame; the support frame is installed along the fore-and-aft direction of a test stand of the support frame; modeling panels are arranged among the upper ends of the support plates; a wind baffle is arranged on the upper end surfaces of the support plates at the front side of the test stand; and the wind baffle inclines towards the rear upper part. The fixed bracket structure replaces a white bodywork for the passenger side air bag impact test, can be used for simulating the internal structure of different automobile modes, and avoids the risk of opening a mould again when the white bodywork is used for the test and defects are found out. Therefore, the utility model improves the universality of the passenger side air bag impact test, and reduces the design cost.
Description
Technical field
The utility model relates to the mechanical shock test field, especially relates to the vehicle impact testing field.
Background technology
The indoor occupant side air bag of car steering plays crucial effects for protection occupant side personnel's safety, so the quality of occupant side air bag performance usually is to estimate one of the key factor of the security of automobile.In the design process of occupant-side safety airbag, need carry out impulse test to its exemplar usually, in order to testing its impact property, the result of emulation is verified.In the impulse test of occupant side air bag, often need air-bag support that air bag is supported, with ram hammer it is clashed into when air bag detonates on support again, utilize the acceleration transducer record data on the ram hammer, the data with record are optimized air bag and support at last.Do not have specialized designs to be used for support that the occupant side air bag is tested now, perhaps directly test,, need to improve design cost again to the vehicle body die sinking if find the defective in the design like this with body in white.The Chinese utility model patent instructions of the CN2703686Y that on June 8th, 2005 was announced discloses a kind of automobile front trolley impact test unit, this device utilizes body in white to test, if the occupant side air bag module is installed on the body in white, carry out impact test after air bag detonated, in case discovery design defect, for example there are defective in moulding panel or windshield angle etc. in the car, then need body support is carried out die sinking again, so not only prolong the design cycle, and designed and developed the also corresponding increase of cost.
The utility model content
The utility model mainly is to solve the professional occupant side air bag test support that do not have that exists in the prior art, perhaps directly test with body in white, if find the defective in the design like this, need to improve the problem of design cost, a kind of fixing rack structure that is used for occupant side air bag impulse test is provided again to the vehicle body die sinking, this structure can be simulated the car inner structure, the occupant side air bag is carried out impulse test,, reduce design cost in case find that design defect can time update.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this fixing rack structure that is used for occupant side air bag impulse test, described structure comprises back up pad, described back up pad is combined to form support frame, described support frame is installed on the fore-and-aft direction of testing table, between described back up pad upper end the moulding panel is set, in the upper surface of the described back up pad of testing table front side windshield plate is installed, described windshield plate tilts to the back upper place.Before the test, the occupant-side safety airbag module is installed in moulding panel lower surface according to actual condition, when air bag detonates ram hammer is ejected, ram hammer and air bag are finished impact, utilization is installed in the acceleration transducer record data on the ram hammer, and then the performance of assessment air bag.The utility model can adjust the size of back up pad and the angle and the size of windshield plate according to the actual condition in the car, substituted the performance that body in white carries out occupant-side safety airbag, avoided the risk of die sinking again, reduced design cost.
As preferably, between the described back up pad of the described windshield plate and the support frame left and right sides, be provided with support bar, described support bar is between described windshield plate rear side and described back up pad upper surface.Because when occupant-side safety airbag detonates, can produce windshield plate and impact, support bar can improve the intensity of windshield plate, avoids damaging because of impulsive force is excessive.
As preferably, the described back up pad of described windshield plate and front side is hinged.Like this can be so that the angle between adjustment windshield plate and the horizontal line improves versatility of the present utility model.
As preferably, described moulding panel extends the skew back below backward.The actual condition of so further simulation passenger side guarantees that the deployed condition of air bag is consistent with real vehicle, makes the impulse test of occupant-side safety airbag more accurate.
The beneficial effects of the utility model are to have substituted body in white to carry out the occupant-side safety airbag impulse test, not only can simulate the inner structure of different automobile types, and can avoid using body in white to test,, need the risk of die sinking again in case find design defect.Improve the versatility of occupant-side safety airbag impulse test like this, and reduced design cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model after air bag detonates.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of fixing rack structure that is used for occupant side air bag impulse test of the present utility model, this structure comprises four back up pads 1 that are vertically welded on the testing table, described four back up pads 1 are in turn connected into the frame body of rectangle, the back up pad 1 of both sides is perpendicular to the fore-and-aft direction of testing table 7 before and after this frame body, and the back up pad 1 of the left and right sides is perpendicular to the left and right directions of testing table 7.Utilize rotary gemel 5 that a windshield plate 2 is installed in the upper surface of the back up pad 1 of front side, this windshield plate 2 is used for the windshield of simulated automotive, between the back up pad 1 of described windshield plate 2 and both sides, support bar 4 is set, described support bar 4 plays the effect of strengthening windshield plate 2 structural strengths between windshield plate 2 trailing flanks and left and right sides back up pad 1 upper surface.On four described back up pad 1 upper surfaces, cover one deck moulding panel 3, and described moulding panel 3 according to the design of real vehicle backward skew back extend downwards, be used for simulating the interior moulding of car of occupant side, as shown in Figure 2, shape after making air bag 8 launch like this is consistent with the shape under the actual condition, warranty test result's accuracy.
During test; at first occupant-side safety airbag module 6 is installed on moulding panel 3 lower surfaces; and be positioned at the rectangular frame that forms by back up pad 1; utilize control element to make air bag 8 detonate; and ram hammer 9 is ejected with air bag 8 bump simultaneously; the acceleration change data of ram hammer 9 were used for assessing the protective value of occupant-side safety airbag for personnel when utilization was installed in acceleration transducer 10 record bump on the ram hammer 9.
Utilize the utility model to carry out the impulse test of occupant-side safety airbag, can replace body in white effect in test, in case find compatibility issue between air bag and the car inner structure, just find the defective of car inner structure, can avoid risk, and then reduce time and the cost of designing and developing body structure die sinking again.This structure can change the structure of framework and the angle of size and windshield plate according to different automobile types in addition, is used for simulating the car inner structure of various vehicles, has improved the versatility of test greatly.
