Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that described herein
Specific embodiment only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1, Fig. 2 and Fig. 4 are the structural representation of the flexible leg discharger of one embodiment of the invention.As it can be seen,
Flexible leg discharger includes equipment supporter 1, launch power source 2, launches support 3, flexible leg connection support 9 and buffer stopper 5, sends out
Penetrating power source 2 and be located at one end of equipment supporter 1, the one end launching support 3 is connected with launch power source 2, and a flexible leg 4 is by soft
Property lower limb connect support 9 with departing mode be located at launch support 3 the other end, buffer stopper 5 is located at another of equipment supporter 1
End, launches support 3 and can slide to the other end of equipment supporter 1 under the dynamic action that launch power source 2 provides and at buffer stopper 5
Stopping under cushioning effect, flexible leg 4 can depart from transmitting support 3 under the effect of inertia and move forward.The present invention's is soft
Property lower limb discharger volume is little, and low cost and accessory are readily produced, change.
In the present embodiment, specifically, the length direction of equipment supporter 1 is provided with the cylinder being positioned at inside equipment supporter 1
Shape guide rail 7, launches support 3 and is provided with four the c-type snap fits 31 can being stuck on guide rail 7, launches support 3 by guide rail 7 and snap fit
The cooperation of 31 is slidably located on equipment supporter 1, solid by screw on the snap fit 31 of the wherein side launching support 3
Surely having a collision block 32, collision block 32 is seen by the side of equipment supporter 1 and is similar to L-type, and its upper part is similar to fin shape, and has
One for the impingement area bumped against with buffer stopper 5, and this impingement area is a plane.Buffer stopper 5 is seen L-shaped by the end face of equipment supporter 1,
It has mounting seat 51 and the buffer part 52 being positioned in mounting seat 51, and the mounting seat 51 of buffer stopper 5 is fixed on equipment supporter 1
A vertical pillar on, buffer part 52 then extends to the top of guide rail 7 inside equipment supporter 1, and and guide rail 7 between interval certain
Distance.Being provided with a buffer spring in buffer part 52, this buffer spring extends along the length direction of equipment supporter 1, and its face
The buffer part 52 of buffer stopper 5 is protruded out to the side launching support 3.So, when launching what support 3 provided in launch power source 2
When rushing at the other end of equipment supporter 1 under dynamic action, launching the collision block 32 on support 3 can be with the buffering elastic on buffer stopper 5
Spring bumps against, and makes transmitting support 3 stop under the effect of buffer spring, simultaneously as the barrier effect of buffer stopper 5, is possible to prevent
Launch support 3 to be come off by equipment supporter 1.
It addition, in order to make transmitting support 3 disengaging launch power source 2 under the effect in launch power source 2 prematurely, this reality
Execute in example, it is preferable that be provided with for holding the magnetic chuck 23 launching support 3 between support 3 and launch power source 2 launching,
Transmitting support 3 is located on launch power source 2 and can be held when not testing to magnetic chuck 23, but when testing, sends out
Penetrate support 3 and can overcome the active force of magnetic chuck 23 under its effect of inertia, transport to the opposite side of equipment supporter 1 along guide rail 2
Dynamic.
In order to reduce the weight launching support 3, in this embodiment, it is preferred that, the material launching support 3 is aluminium alloy,
And transmitting support 3 is provided with some hollow-out parts 33, the most both can reduce the gross mass of flexible leg discharger, can reach again high
The requirement of intensity.
As it is shown on figure 3, in the present embodiment, wrap for connecting the flexible leg connection support 9 of flexible leg 4 and transmitting support 3
Including flexible leg clamping support 91 and flexible leg supports support 93, flexible leg supports support 93 and is fixed on transmitting support 3, and it is long
Degree direction is perpendicular to launch support 3.Flexible leg clamping support 91 is located at flexible leg and is supported the upper and lower of support 93, is used for pressing from both sides
Tight flexible leg 4.Flexible leg clamping support 91 is seen the most C-shaped by the end face of equipment supporter 1, and it includes two cards, these two
Distance between card, equal to the diameter of flexible leg 4 corresponding position, so, can clamp flexible leg 4 so that it is props up departing to launch
The when of frame 3, do not have the phenomenon disorderly flown, it is ensured that the precision of position of collision.The vertical plane of flexible leg 4 need to be fitted completely
Support the corresponding surface of support 93 in flexible leg, be so easy to launch the speed of support 3 and energy passes to flexible leg 4.
It addition, this flexible leg discharger also includes an alarm device 6, alarm device 6 is positioned at the installing of equipment supporter 1 and sends out
Penetrate one end of power source 2.When needs start to test, alarm device 6 can send sound and light alarm signal, reminds testing crew to withdraw
Pilot region, thus the safety of guarantee test personnel.In this embodiment, it is preferred that, launch power source 2 is cylinder, the most not
It is only capable of keeping the cleaning of environment, moreover it is possible to the efficiency of guarantee test.Certainly, in other embodiments, launch power source 2 can also be
Oil hydraulic cylinder etc..Further, in the present embodiment, in the both sides of equipment supporter 1, protective plate 8 is installed along its length, anti-
Backplate 8 is positioned at one end arranging buffer stopper 5 of equipment supporter 1, after this can prevent flexible leg 4 from striking vehicle, and the fragment of vehicle
Splash, damage flexible leg discharger.
The using method of this device is described below in detail.
First, when doing flexible leg impact test, gas is compressed by booster pump, the air inlet pipe of input cylinder, through
Cylinder 2, until transmitting support 3 can be got by cylinder with the speed of 40km/h, cylinder can be got the speed of transmitting support 3 and pass through
Air pressure in cylinder is weighed, and the experience summed up according to many experiments, when the air pressure in cylinder reaches specific numerical value
Can get launching support 3 with the speed of 40km/h.Launch after support 3 is got and will slide along guide rail 7 and finally hit
It is located at the buffer stopper 5 of the other end of equipment supporter 1, launches support 3 due to the cushioning effect of buffer stopper 5 and will be still on guide rail 7,
And flexible leg 4 can depart from the flexible leg on transmitting support 3 under the effect of inertia and connect support 9 and move forward and hit
Hit vehicle, the sensor on flexible leg 4 can be demarcated afterwards.
To sum up, the flexible leg discharger that the present invention provides is by the monitoring to the air pressure in cylinder, it is ensured that launches and props up
The speed that frame 3 is got, be ensure that the precision of flexible leg 4 position of collision, passes through flexible leg by flexible leg clamping support 91
Support support 93 and ensure that the energy launched between support 3 and flexible leg 4 and speed transmission, make the flexible leg of the present invention launch dress
Put and there is higher test accuracy.It addition, the present invention is compared to the equipment of market, volume is little, light weight, energy big, saves
Equipment cost.Each parts in the present invention can need to split according to different purposes, and each parts easily produce,
The part replacement damaged in process of the test is convenient.Use cylinder as launch power, can not only ensure that environment is clean, moreover it is possible to ensure
Test efficiency.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
