Description
Technical field
The utility model belongs to test unit technical field, relates to a kind of rigid leg and launches adjusting bracket.
Background technology
Along with the development of society, the raising of people's living standard, automobile becomes the main traffic instrument of people's trip gradually, and the attention degree for vehicle safety performance is also more and more higher.In automotive safety research field, pedestrian protecting safety is very important ingredient, and pedestrian protecting design is relevant to vehicle front moulding, layout and structure.Pedestrian is the disadvantaged group in traffic, once have an accident, the leg of pedestrian is one of the most vulnerable position.
When there are lower limb and colliding in automobile and pedestrian, impact force and the axial moment of torsion of possible leg combine, injury can be caused to be multiplied, along with the acceleration of the collision before car and pedestrian's lower limb subsequently, pedestrian lower leg is subject to shearing force and bending force, thus causes the injuries such as the fragmentation of pedestrian's long bone fracture, knee cap and ligament injury.
It is the injury that reduction pedestrian is subject to when automobile and pedestrian collision, people work out pedestrian's leg type knocker and test in the lab, pedestrian is by the injury values be subject to during car crass to use rigid leg to reflect really in the lab, thus the front end of automobile is arranged to the less moulding of pedestrian injury, layout and structure, the injury be subject to when maximized reduction pedestrian and collision happens.In the process of test collision, relate to the requirement of impact velocity and position of collision, and existing rigid leg emitter can only be launched towards a direction, and launch accuracy is lower, the speed that rigid leg clashes into and position can not reach the requirement of test setting, cause testing the data recorded comparatively single, precision is lower, reduces the reference value of test figure.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, proposes a kind of rigid leg and launches adjusting bracket, solve the test accuracy how improved when existing rigid leg and automobile collide.
The purpose of this utility model realizes by following technical proposal: a kind of rigid leg launches adjusting bracket, it is characterized in that, comprise support reinforcing plate, described support reinforcing plate have several emission angle holes, line between any two emission angle hole circle hearts in several emission angle holes tilts, the side of described support reinforcing plate is provided with fixed head, the opposite side of described support reinforcing plate is fixed with the baffle plate for putting rigid leg, with fixed head, support reinforcing plate is connected through corresponding emission angle hole by least two bearing pins mutually with fixed head, thus make baffle plate be obliquely installed relative to vertical direction or vertically arrange.
Fixed head is connected mutually with transmitter, rigid leg is placed in baffle plate, to be inserted in different emission angle holes by two bearing pins thus to regulate the angle of support reinforcing plate and baffle plate, namely the angles of rigid leg is changed, make rigid leg by the angle set and speed after ejection and collision happens, improve test accuracy when existing rigid leg and automobile collide, and measured by the collision that angle when changing rigid leg ejection can be carried out repeatedly under different situation, make test figure have more reference value.
Launch in adjusting bracket at above-mentioned a kind of rigid leg, described baffle plate is arc convex near the side of support reinforcing plate, and the opposite side that described baffle plate is used for putting rigid leg is arc-shaped concave.Rigid leg is arranged in arc-shaped concave, is enclosed in baffle plate, and baffle plate plays the effect of location to rigid leg, makes rigid leg in the process of launching, keep stable, can not change the direction of transmitting because of unexpected acceleration.
Launch in adjusting bracket at above-mentioned a kind of rigid leg, described fixed head comprises fixed part and adjusting portion, described fixed part and adjusting portion perpendicular, described fixed part has several pilot holes and several fixed orifices, described adjusting portion has the through hole that several are corresponding with emission angle hole.Fixed head is positioned on transmitter by pilot hole, is connected mutually by fixed orifice and transmitter, by the angle of through hole adjustment fixing plate, i.e. and the angle of controllable register, thus change angle when rigid leg is launched.
Launch in adjusting bracket at above-mentioned a kind of rigid leg, the top of described support reinforcing plate is fixed with hook, and one end of described hook is positioned at the top of baffle plate.The top of rigid leg hangs on hook, and hook makes rigid leg be arranged in baffle plate can not to come off, and hook improves the installation stability of rigid leg, and angle when rigid leg is launched and speed are launched by the angle set and speed, thus raising test accuracy.
Launch in adjusting bracket at above-mentioned a kind of rigid leg, the middle of described support reinforcing plate opposite side has breach, described baffle plate sealing gap.Breach plays the effect absorbing distortion, and support reinforcing plate better can be connected with baffle plate, reduces the vibrations between baffle plate and support reinforcing plate, and angle when rigid leg is launched and speed are launched by the angle set and speed, thus improve test accuracy.
Launch in adjusting bracket at above-mentioned a kind of rigid leg, described support reinforcing plate is resisted against the middle of baffle plate side, and described baffle plate is connected mutually by sunk screw and support reinforcing plate.Be connected by sunk screw, ensure that baffle plate is for putting the slickness of rigid leg side, sunk screw can not have influence on putting of rigid leg, namely also would not have influence on the transmitting of rigid leg, improves test accuracy.
Launch in adjusting bracket at above-mentioned a kind of rigid leg, described support reinforcing plate adopts aluminium to make.Support reinforcing plate adopts aluminium, increases the intensity of support reinforcing plate, and support reinforcing plate can not be out of shape when launching rigid leg, and angle when rigid leg is launched and speed are launched by the angle set and speed, thus improve test accuracy.
Compared with prior art, the rigid leg that the utility model provides is launched adjusting bracket and is inserted in different emission angle holes by bearing pin, rigid leg can be launched obliquely, make rigid leg can along multiple different angular emission, make up the height that rigid leg falls to rum point at disengaging baffle plate, make impact test more realistic, improve test accuracy.
