The utility model drives the safety protection mechanism of the hydraulic ram of car back door upset, when car back door upset opens to level attitude and becomes the horizontal lifting platform, the horizontal lifting platform, slide block and hydraulic ram form triangle, the hydraulic ram that drives the upset of car back door to open becomes the load-bearing digonal link of horizontal lifting platform, simultaneously, the long draw be hinged and short rod are also along with the Automatic-expanding push-and-pull rod that is in line is opened in the upset at car back door, the horizontal lifting platform, slide block also forms triangle be hinged straight long draw and short rod, be hinged straight long draw and short rod becomes one of horizontal lifting platform protection digonal link, the rigid construction of its long draw and short rod can protect the hydraulic ram that drives the car back door hydraulic circuit produce leak or in let out and avoid damaging during the load-bearing lifting, hinge-point between long draw and short rod can be packed up by auto-folder when the closure of car back door.During use, hydraulic ram drives the upset of car back door to open, and long draw and short rod Automatic-expanding thereupon form triangle, and jacking system drives horizontal lifting platform load-bearing lifting under the driving of HM Hydraulic Motor; Flip closed under the driving of car back door at hydraulic ram, short rod is rotated down withdrawal together with downward drive long draw with the hinge-point of long draw under Action of Gravity Field, the hinge axis of the hinged long draw of horizontal lifting platform can move along sliding tray, make hinge cross dead point, stop action while continuing to rotate to the complete closure in car back door.
The accompanying drawing explanation
Structural representation when Fig. 1 is convertible back door of the present utility model horizontal lifting;
Fig. 2 is the structural representation overturn while opening in convertible back door of the present utility model;
The structural representation that Fig. 3 is lifting mechanism of the present utility model.
In figure: 1 horizontal lifting platform, 2 long draws, 3 short rods, 4 slide blocks, 5 hydraulic rams, 6 sliding trays, 7 leading screws, 8 load-bearing nuts, 9 HM Hydraulic Motor, 10 multiple degree of freedom hoisting mechanisms, 11 jacking systems.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1～Fig. 4, a kind of safety protection mechanism that drives the hydraulic ram of car back door upset, it comprises two slide blocks 4, car back door and two hydraulic rams 5, described two slide blocks 4 are placed in respectively the both sides at car back door, slide block 4 is connected with the jacking system 11 of vehicle body, the car back door is the bottom reversed formula, the bottom at car back door respectively with the bottom-hinged of the slide block 4 that is placed in both sides, car back door, cylinder bar and the car back door of hydraulic ram 5 are hinged, the cylinder body of hydraulic ram 5 is hinged with the slide block 4 that is positioned at homonymy, also comprise long draw 2 and two short rods 3 of two, one end of described long draw 2 and an end of short rod 3 are hinged, the other end of long draw 2 is all hinged with the car back door, the hinge-point of long draw 2 arranges sliding tray 6, the other end of short rod 3 is all hinged with the slide block 4 that is positioned at homonymy, the hinge-point of short rod 3 and slide block 4, the hinge-point of the cylinder body of hydraulic ram 5 and slide block 4 all is positioned at a side of same slide block 4, the opposite side of same slide block 4 and the jacking system of vehicle body 11 are connected.The structure of described jacking system is: jacking system is spiral lift device, the top of the leading screw 7 of spiral lift device is connected in the column of vehicle body by multiple degree of freedom hoisting mechanism 10, the dynamical axis of the bottom of leading screw 7 and HM Hydraulic Motor 9 is connected, load-bearing nut 8 is connected with slide block 4, and load-bearing nut 8 is threaded with leading screw 7.
