Movable platform sling is crossed, to provide certain activity surplus；
By idle rod 820, to provide certain activity surplus.
Fig. 4 a, 4b are respectively 2 pawls of the invention, the structural scheme of mechanism of the telescopic pole of 3 palmula blocks；Fig. 5 a, 5b are this hair
The stroke schematic diagram of the stroke groove of bright telescopic pole.As shown, first telescopic pole and described second scalable
The finger 902 strut stroke groove 901 with different depths and slided in the stroke groove makes institute by the stroke groove
It states the first telescopic pole and second telescopic pole is capable of providing different strokes.
In one embodiment of the invention, overturning lifting linear actuator and the lifting linear actuator can be with
For hydraulic cylinder, pneumatic linear actuator, electric cylinder or electric pushrod.
The present invention also provides the embodiments of control method comprising:
When beginning, tailgate loading plate 100 is in the closed state for being vertically attached to compartment.This when, overturning lifting is straight
Line actuator 510 extends, and first swing arm 610 and the channel bar 710 is driven to rotate, and the channel bar 710 drives described the
One telescopic pole 410 shortens to realize that the tailgate loading plate 100 is turned to the first loading position by plumbness；
In first loading position, in overturning lifting linear actuator 510 and the lifting linear actuator 520
After isometric, the overturning lifting linear actuator 510 shortening drive synchronous with the lifting linear actuator 520 tailgate is held
100 level of support plate drops to the thick termination tread surface of the tailgate loading plate 100；
The overturning lifting linear actuator 510 is synchronous with the lifting linear actuator 520 to be shortened, and first stroke is passed through
Mechanism and second stroke mechanism the first pendulum described in overturning lifting linear actuator and lifting linear actuator synchronous drive
There is provided the tailgate loading plate 100 further inclined activity surplus under swing arm 610 and the second swing arm small angle oscillation, so that
The nib contacts ground of the tailgate loading plate 100.
Further, can also include:
The overturning lifting linear actuator 510 is synchronous with the lifting linear actuator 520 to be extended, and the tailgate is held
Support plate 100 is lifted to first loading position；
The overturning lifting linear actuator 510 shortens, so that the tailgate loading plate 100 is flipped up predetermined angular；
Overturning lifting linear actuator 510 extends, so that the tailgate loading plate 100, which downwardly turns over, returns to described the
One loading position；
The overturning lifting linear actuator 510 extends, and can be stretched by first telescopic pole 410 and described second
The stroke groove for the different depth having in contracting strut 420 and the finger slided in the stroke groove are stirred the rotation of claw cushion block and are mentioned
The further stroke supplied, so that the tailgate loading plate 100 downwardly turns over a predetermined angular by first loading position.
Wherein, overturning lifting linear actuator is consistent with lifting linear actuator specifications and models, exchanges completely.Only overturn
Linear actuator execution open and close door and cargo platform more than lifting linear actuator is lifted to be lower than under tailgate altitudes upper
The tilting action of position is only distinguished from execution movement with showing.
Linear actuator can be hydraulic cylinder, pneumatic linear actuator, electric cylinder, electric pushrod etc..
Hereinafter, the course of work is described step by step again.
Step 1) overturning lifting linear actuator elongation, the first swing arm drive hinged channel bar, and channel bar drive connects therewith
The first telescopic pole connect shortens, and tailgate bearing plate overturns enabling, band of second telescopic pole in tailgate bearing plate simultaneously
Dynamic lower shortening.With the gradually elongation of overturning lifting linear actuator, it is (scalable that two telescopic poles reach 1 position of hard support
The shortening stroke end of strut is no longer shortened), overturning lifting linear actuator then extends, and the first swing arm drives channel bar, slot
Bar walks empty slot stroke, and no longer drive telescopic pole shortens.It is held until overturning lifting linear actuator is elongated to lifting straight line
Row device is consistent, and overturning door opening process of the tailgate in upper position is completed.
Step 2) overturning lifting linear actuator is synchronous with lifting linear actuator to be shortened, tailgate bearing plate (or and goods
Object) decline under gravity, until the thick termination tread surface of tailgate bearing plate, decline process is completed.Overturning lifting straight line
Actuator and lifting linear actuator then shorten, and tailgate load-bearing plate thickness end cannot decline, two is scalable again with ground face contact
Strut can not shorten in 1 position of support firmly, in this way, tailgate bearing plate (or and cargo) is held under gravity with tailgate
The hinged shaft of weight plate and telescopic pole is that shaft is tilted in lower position, and tip and ground face contact until tailgate bearing plate are completed
Tilting procedure.
Position turns under step 3), rises and shutdown is lower position inclination, decline the inverse process with door opening process, herein not
It repeats again.
Step 4) cargo platform is as follows lower than tilting procedure of the tailgate bearing plate under the first loading position altitudes, tail
Plate at the first loading position, overturning lifting linear actuator shorten, tailgate carries out shutdown movement at this time, tailgate bearing plate into
When certain angle range (such as 60--80 degree) is arrived in row shutdown, stop shutdown movement, next execute door opening action, with overturning act
The gradually elongation of linear actuator is risen, two telescopic poles shorten to 2 positions of hard support, until platform tip and cargo platform
Contact.Overturning lifting linear actuator continues to extend, and swing arm drives channel bar, and channel bar is walked empty slot stroke, no longer driven scalable
Strut shortens.Until overturning lifting linear actuator be elongated to lifting linear actuator it is consistent, cargo platform lower than tailgate height
Tilting procedure in the case of degree in the first loading position is completed.After loading and unloading, pass can be realized by carrying out door-closing operation
Door.
First telescopic pole and second telescopic pole is made to be capable of providing difference by the stroke groove
Stroke.Specifically, with further reference to Fig. 4 a, 4b；Fig. 5 a, 5b illustrate for Fig. 5 a now with Fig. 4 a, when shutdown state, dials
For pin in a straightway the top, door opening process, finger is topmost moved to the lower section of a straightway, door opening action from a straightway
When completion, finger is in the lower section of a straightway, and the claw cushion block of finger control is without rotation.A straightway and b spiral section are handed over
The place connect, a straightway have a sunk step, and depth is identical with b spiral section, and such tailgate bearing plate is in door closing procedure
In, finger enters b spiral section from the lower end of a straightway, the partial groove depth of b spiral section and the handover of c straightway in c straightway,
Into c sections of tops, c straightway is identical as the part groove depth that d spiral section is connected, into d spiral section, d spiral section and a straightway phase
The partial groove depth even completes door closing procedure in a straightway, into a straightway into a straightway upper end, in the process,
The claw cushion block of finger control is rotated.When being in c straightway or d spiral fragment position such as finger, stop door closing procedure, overturning
It lifts linear actuator and executes door opening action, finger is moved to the lower section of c straightway, when at this moment claw cushion block is with respect to shutdown state
Turn over a relative angle, the pawl and underlay of claw cushion block are staggered a relative position, and telescopic pole is to than 1 position of normal hard support
Short one section of 2 positions of hard support are shortened, and such tailgate bearing plate can be realized in cargo platform lower than tailgate bearing plate the
Inclination under one loading position altitudes.This slot is one kind of the present embodiment, can have the mode of other slot to realize
Stir the rotation of claw cushion block.The claw of the present embodiment is two pawl structures, can be multijaw structure.
