Description
Technical field
The present invention relates to field of mechanical technique, specifically a kind of test frock of knee airbag.
Background technology
Along with raising and the automotive safety development of technology of consumer to the vehicle safety performance requirement; knee airbag is developed and begins to be applied in the automobile; provide protection in order to shank and the knee position to the passenger when collision accident takes place; the displacement of occupant restraint in collision process simultaneously provides better protection effect with auxiliary security band and other air bag.Knee airbag generally is installed in the interior instrument panel of car, and driver side and copilot's side can be installed simultaneously, also a side can be installed separately.In order to reach desirable protection effect; be convenient to the panel assembly layout simultaneously, knee airbag generally is installed in instrument panel position on the lower side, and air bag puts that airbag launches to be full of from bottom to top when quick-fried; between occupant's shank and knee and instrument panel, form inflatable air cushion, buffer protection is provided.
Can both be effectively protected when being in different sitting posture in order to ensure the different occupant of height build, in the performance history of knee airbag, must carry out verification experimental verification to different operating modes.Traditional test method is that the testing dummy is positioned in the vehicle body environment, and different distance and angle that dummy's shank and instrument panel be set test, and the equipment that this test method is used requires high, and each test adjustment time is long, the cost height.
In order to raise the efficiency, reduce experimentation cost, begin to adopt frock to simulate actual panel board for car bodies and occupant's shank in the industry.But dirigibility and the adaptability of general frock are not strong, be difficult to simulate the diversity of occupant's height build and sitting posture in the actual condition, and the instrument panel of each project is different with the vehicle body environment, it is also different with angle that the test shank of corresponding requirements arranges the position, often new projects just need exploitation to make a cover even many cover test frocks, the frock process-cycle is long, and the cost height influences the exploitation of new projects.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, design can be simulated the instrument panel parts of knee air bag periphery and occupant's shank and knee etc., frock has adjustability flexibly, not only can satisfy some projects to the requirement of test parameterss such as different angles, distance, and only change the fraction fixture component and just can be applied to other project, realize that a cover frock is applied to a plurality of disparity items, saves test frock manufacturing time and cost.
For achieving the above object, design a kind of test frock of knee airbag, comprise bearing, the instrument panel analogue unit, the air bag fixed cell, the shank mould, it is characterized in that: described bearing adopts the rear side on level frame to establish vertical frame and regulate support with the front side is vertical respectively, described adjusting support is slidingly connected on the level frame along X-direction, the instrument panel analogue unit is slidingly connected to the leading flank of vertical frame along Z-direction, described air bag fixed cell is fixed on the instrument panel analogue unit, the upper end edge Y-direction of two shank moulds, Z-direction is slidingly connected on the trailing flank of regulating support, the lower end edge X-direction of two shank moulds, Y-direction is slidingly connected on the level frame between vertical frame and the adjusting support.
Described adjusting support is slidingly connected on the level frame along X-direction, horizontal guide rail outside vertically establish the front and back, level frame upper edge of frame front side, and the bottom rail of regulating support is connected on the outer horizontal guide rail.
The upper end edge Y-direction of described two shank moulds, Z-direction are slidingly connected on the trailing flank of regulating support, vertically establish upright slide rail what regulate support, the back side rail of last sideslip rail is connected on the upright slide rail, and the upper end of two the shank moulds right rail of a first from left respectively is connected on the sideslip rail.
The level frame that the lower end edge X-direction of described two shank moulds, Y-direction are slidingly connected between vertical frame and adjusting support is, at front and back, level frame upper edge horizontal guide rail outside establishing, downward sideslip rail about rail connects on the horizontal guide rail outside, the lower end of two shank moulds rail respectively is connected on down on the sideslip rail.
The level frame that the lower end edge X-direction of described two shank moulds, Y-direction are slidingly connected between vertical frame and adjusting support is, before and after the level frame upper edge to establishing interior horizontal guide rail, downward sideslip rail about rail connects on the interior horizontal guide rail, the lower end of two shank moulds right rail of a first from left respectively are connected on down on the sideslip rail.
Described instrument panel analogue unit is, the fixed base plate respectively in the left and right sides of the leading flank of bracing frame, about the leg of the left and right sides at the supporting seat back side is separately fixed on the front of two base plates, the instrument panel face is welded on the front of supporting seat, on the bracing frame about the air bag fixed cell is fixed in the middle of two base plates.
Described air bag fixed cell is fixed an open-and-close mechanism for adopting at the air bag bearing, articulates air bag at open-and-close mechanism to constitute; The top of described air bag bearing is fixed on the bracing frame.
Described open-and-close mechanism is fixed on the air bag bearing, be included in and fix a compactor spanner on the air bag bearing, the front end of the push rod of compactor spanner connects movable block, two pin-and-holes about movable block is provided with are provided with two fixed pins at the leading flank of the air bag bearing at corresponding two pin-and-hole places and constitute; Be fixed in behind the support of sheathed air bag in the pin-and-hole of movable block on the described fixed pin.
Guide runner on the upper end difference hinged of two shank moulds, last guide runner rail is connected on the sideslip rail.
The lower end of two shank moulds is hinged guide runner once respectively, and following guide runner rail is connected to down on the sideslip rail.
The present invention compares with prior art, and the instrument panel analogue unit independently arranges, and different project only needs to make separately this module unit and changes up and get final product during test, and the other parts of testing frock all can be continued to use; Adopt the folding of compactor spanner that air bag is installed, can in 20 seconds, finish, the method that has replaced traditional bolt air bag, can guarantee that air bag finishes the quick-fried process of whole point in 1 minute leaving insulation can, thereby solve that air bag leaves that insulation can overlong time temperature is tending towards room temperature and the problem that can't satisfy the verification experimental verification condition; Can also satisfy special item for the specific (special) requirements of two shank different angles and distance, not needing is that frock is overlapped in a project manufacturing more.
