The removable support baseboard 4 realizes Integrated test facility and is easy to arrange, any angle is adjustable and fixed.
The multi-angle collision of the riding people such as bicycle, electric vehicle and motorcycle may be implemented in the present embodiment.
Embodiment two
Continue as shown in Figure 1, what is different from the first embodiment is that the present embodiment is changed as follows on the basis of example 1
Into:
The first support bar 101 and the second support bar 102 are disposed as to adjustably adjust bar.The scalable tune
Pole can be various forms of telescopic rods in the prior art, set highly adjustable for the first, second support rod, can be applicable in
The test demand of different size model ride-on vehicle.
The multi-angle collision of the riding people such as bicycle, electric vehicle and motorcycle not only may be implemented in the present embodiment, can be with
Meet different size model ride-on vehicle impact test problem.
Embodiment three
Continue as shown in Figs. 1-2, unlike embodiment one, two, the present embodiment is on the basis of above-mentioned two embodiment
It is upper to be improved as follows:
The length in the second curved support structure 1012 direction parallel with the rear-wheel central axis of the ride-on vehicle
Length for L1, the first curved support structure 1011 direction parallel with the front-wheel central shaft of the ride-on vehicle is
L2, the L1 are greater than the L2, and the length of the prominent rear-wheel of the rear-wheel central axis is prominent less than the front-wheel central shaft
The length of the front-wheel is because L1 is larger, and the length of the prominent rear-wheel of rear-wheel central axis need not be too many, as long as outstanding
Length can be with the concave arc face contact of the second curved support structure 1012.
The L1 is designed as to be greater than the L2, is designed as L1 to be less than or equal to the L2 if having the advantages that, that
The length of the prominent rear-wheel of rear-wheel central axis is greater than or protrudes equal to the front-wheel central shaft length of the front-wheel, this
Sample, during ride-on vehicle moves forward in impact test, when rear-wheel central axis is run at first support bar 101,
Because the length of the prominent rear-wheel of central shaft is longer, first support bar 101 will certainly be encountered, tested to influence ride-on vehicle
Athletic posture in journey；And if L1 is designed as to be greater than the L2, then the length of the prominent rear-wheel of rear-wheel central axis there is no need to
It is too long, in this way, during ride-on vehicle moves forward in impact test, when rear-wheel central axis runs to first support bar
When at 101, first support bar 101 will not be encountered, therefore the L1 is designed as to guarantee that ride-on vehicle exists greater than the L2
When moving forward during test, the influence of the unsupported bar of athletic posture.
It, can be in actual application as previously mentioned, curved support structure is fixed on support rod by welding manner
Need to weld different size of curved support structure according to the test of different size model ride-on vehicle.
The multi-angle collision of the riding people such as bicycle, electric vehicle and motorcycle not only may be implemented in the present embodiment, can be with
Meet different size model ride-on vehicle impact test problem.
Example IV
Present embodiments provide a kind of collision test method for riding people's collision test device, comprising the following steps:
S1, ride-on vehicle 5 is placed on the guide rail 2, adjusts the height of first support bar 101 and second support bar 102
Degree makes it suitable for the ride-on vehicle, and the front axle center axis of ride-on vehicle 5 is accommodated and is arranged in 101 end of first support bar
The first curved support structure 1011 concave curved surface in, while by rear center's axis of ride-on vehicle 5 accommodate be arranged second
In the concave curved surface of second curved support structure 1012 of 102 end of support rod；
The forms of collision that S2, basis design in advance, by moving the universal wheel of 4 bottom of support baseboard for guide rail 2 and riding
5 it is moved to the optimum position for being suitble to the forms of collision by bus, and is fixed by directional wheel；
The forms of collision that S3, basis design in advance, rotary turnplate 3 make guide rail 2 and ride-on vehicle 5 rotate to and this is suitble to touch
The optimum position of form is hit, then by 3 locking of turntable；
S4, during impact test, pass through jobbie, for example damping block hits entire riding people's impact test dress
It sets, after being impacted, ride-on vehicle is detached from the first, second support rod, the straight ahead on guide rail 2；
S5, make the vehicle collision ride-on vehicle 5 that straight line is exercised on guide rail 2, according to impact test data, exist to riding people
Injured situation in collision is studied.
The embodiment of the present invention has the following beneficial effects:
(1) present invention includes guide rail, turntable and removable support baseboard, places ride-on vehicle on guide rail, moves support
Guide rail and ride-on vehicle can be carried to any position and be arranged by bottom plate, and turntable can drive guide rail and ride-on vehicle to rotate
