Further, described back door oil cylinder 5 is arranged on above car body, and the hydraulically extensible bar of back door oil cylinder 5 and the tail gate of Guan Bi are 90 °.
Further, described arc connecting plate is 3/4 circular arc connecting plate.
Further, described rotating shaft I 1 and rotating shaft II 3 are separately positioned on the two ends of arc connecting plate, and hinge 2 is arranged on the arc part of arc connecting plate.
Further, described triangular coupling rod 8 is made up of vertical straight-bar and two tilting bars axisymmetricly, and the top of two tilting bars is fixedly welded on the middle and upper part of vertical straight-bar, and vertical straight-bar overlaps with back door central sill.
Further, described little concentric shafts 7 is separately positioned on vertical straight-bar and the bottom of two tilting bars axisymmetricly, in the same horizontal line, little concentric shafts 7 and locking pin member II 12 on vertical straight-bar are on same vertical curve for little concentric shafts 7 on tilting bar and locking pin member I 11 place on crossbeam 10.
Further, described locking pin member I 11 and locking pin member II 12 are the upper end bearing pin with spacing preiection, the locating slot that locking pin member I 11 is offered on beam outside the both sides at car back door moves up and down, and the locating slot that locking pin member II 12 is offered on the central sill at car back door moves up and down.
Further, described gear pipe 9 is the square tube of 2 long 180mm of 40mm*40mm*3mm and is welded in the both sides of back door central sill, and one end of side cross tube is pushed up on the panel at back door, and the other end is connected by iron plate and strengthens.
Further, being provided with downward inclined ladder shape contracting tongue outside the both sides at described car back door bottom beam, inclined ladder shape contracting tongue arranged outside has lock 6, and when closing at car back door, inclined ladder shape contracting tongue is fastened in lock 6.
The carrying out practically process of the side entrucking hydraulic pressure rear-door opening device of the present invention is:
First accurately make by drawing hydraulic pressure to live back door, it is ensured that locking pin member I 11 and locking pin member II 12 the locating slot up and down motion smoothness in beam and back door central sill can not damp outside the both sides at back door.When back door oil cylinder 5 all stretches out (as shown in Figure 1 state) this be the closedown state strong with locking at back door.When back door to be opened, first in driver's cabin operation knob to make the loculus of back door oil cylinder 5 obtain oily, cylinder rod is retracted and is driven connecting plate II 3 rotation around the shaft, and triangular coupling rod 8 can only be risen under the constraint of gear pipe 9 by hinge 2 under the drive of connecting plate in swing simultaneously, the link locking pin member I 11 at back door of crossbeam 10 that rises through of triangular coupling rod 8 rises together with locking pin member II 12 and raises, the locating slot that locking pin member I 11 is offered on beam outside the both sides at car back door moves to topmost, the locating slot that locking pin member II 12 is offered on the central sill at car back door moves to topmost, locking pin member I 11 and locking pin member II 12 are thus lifted to top dead centre and are not rising, after making contracting tongue exit lock 6, back door is opened；Now, back door oil cylinder 5 also to continue retraction, triangular coupling rod 8 is in continuing the process risen, the crossbeam 10 being connected with triangular coupling rod 8 rotates around three little concentric shafts 7, crossbeam 10 rotates from initial vertical state to level, now whole back door will continue to rotate to oil cylinder with rotating shaft III4 for center of rotation under the pulling of oil cylinder and be fully retracted into, and it is 130 degree that back door now opens angle, and vice versa.
nullThe present invention is by beam outside the both sides at back door and increases by 2 locking pin members I 11 that can move up and down and locking pin member II 12 in central sill，The outer beam of two frames making back door is interior with central sill with active pin shaft，These 3 locking pin members and back door crossbeam 10 connect together，There is an oil cylinder of box top to control again with triangular coupling rod 8 and connecting plate，Oil cylinder stretch out with retract in drive the rotation of connecting plate，And the rotation of connecting plate drives back door connecting rod and the up and down motion of crossbeam 10，And the up and down motion of crossbeam 10 interlocks 3 moveable locking pin members in back door，Thus realizing switch and the locking at back door，And stretching out with retraction of box top oil cylinder is control handle in driver's cabin，Operator's control handle in driver's cabin of not getting off behind soot can realize the unlatching at back door，Behaviour does the realization of big case inner pushing plate the release of rubbish again.
