15 two sides of compartment are placed equidistant with six support constructions respectively, and each support construction includes supporting rod seat 10 and support rod
11, supporting rod seat 10 is set to the outside of 15 two curb girders of top of compartment, and 11 one end of support rod is articulated with supporting rod seat 10, the other end
If the first roller 12 is located at 11 end of support rod there are two rotatable roller, the second roller 13 is located at 11 middle part of support rod, rolling
Son is installed in sliding slot 4, and supporting rod seat 10 is equipped with limited block, the rotation angle of strut for limiting.
Driving structure is set to 15 rear and front end of compartment, and connecting rod base 5 is set to 15 end side of compartment, first connecting rod 6 one
End is hinged with connecting rod base 6, and the other end and second connecting rod 7 are hinged, and 7 other end of second connecting rod is articulated with ipsilateral by straight pin 14
Top cover, cylinder block 9 are set to 15 end of compartment, and the tail portion of cylinder 8 is articulated with cylinder block 9, and the piston rod of cylinder 8 is articulated with second
Connecting rod 7.
The lower resistance full-open type lorry roof system is that two sets of identical roof systems are symmetrically arranged in vehicle
Top, when closing, can be completely covered by vehicle roof, can be completely exposed vehicle roof after unlatching.
When roof system is in the closed position, left and right top cover is supported by the six roots of sensation support rod at middle part respectively, top cover
It is vertically pressed in by the sliding slot in crossbeam on the first roller and the second roller of support boom end, the supporting surface of support rod is pressed in vehicle
On the curb girder of body, the pin hole of end is articulated with supporting rod seat, and top cover gravity is undertaken by car body completely at this time, first connecting rod,
Two connecting rods and cylinder are not subject to the gravity of top cover.

In entire opening process, the movement of top cover is divided into first translating turns round two motion processes again.In translational motion
Top cover gravity is undertaken by support rod with car body completely, and cylinder thrust only needs to overcome roof bow sliding slot and the first roller, second
Rolling frictional resistance between roller, therefore required cylinder thrust also very little.When top cover starts to do centered on strut bore
After rotary motion, the resistance of motion that cylinder thrust need to overcome becomes the resistance that top cover center of gravity gravity forms support rod bore
Square.Due to top cover center of gravity at this time away from the centre of gyration apart from close, the steering resistance square that cylinder need to overcome is also smaller.
It is reverse motions process that top cover, which is closed and opened,.
Each embodiment of the utility model is described above, above description is exemplary, and non-exclusive, and
