Example 2
the differences from the embodiment 1 are mainly as follows: compared with the embodiment 1, the installation positions of the chassis telescopic folding related components are exchanged in the front and back directions, as shown in fig. 12, the reinforcing beam 11 is installed at the bottom of the front vehicle bottom plate 30, and other chassis telescopic folding related components are all installed at the bottom of the rear vehicle bottom plate 15, and are correspondingly adjusted in the specific implementation direction; the folding bottom plate does not move forwards but moves backwards after rising, and the folding seat (the second row seat) is driven to be placed below the rear part of the third row seat; the folding top is folded in the same way, but is not translated forwards when folded, but is placed on site on the floor behind the first row of seats; the folding door is folded in the same manner as the folding doorsill, next to the folding roof, onto the floor behind the first row of seats. Please refer to fig. 11, 12 and 13.
The working principle and the using process of the invention are as follows: when the vehicle extension expandes, refer to fig. 2, at first, driving-disc 14 is driven to drive by the output of driving motor 10, driving-disc 14 runs through the logical groove of reserving on the mount pad 9, and carry out circular motion through the annular protrusion with 12 surperficial annular grooves looks adaptations of rotatory pipe 12, meanwhile protruding and the spacing block of the 12 surperficial annular grooves of rotatory pipe of protruding on the mount pad 9 inner wall, guarantee that the lateral position of rotatory pipe 12 can not appear changing, and simultaneously, rotatory pipe 12 and 2 threaded connection of reinforcing longeron, make reinforcing longeron 2 be lateral motion in the inboard of rotatory pipe 12.
At the same time, the three sets of fasteners of the vehicle body are operated, and the front screw 24 is retracted into the front vehicle body 1, releasing the threaded connection between the front vehicle body 1 and the rear vehicle body 21.
Referring to fig. 6, the small motor on the roof of the front body 1 drives the rotating wheel 27 to wind the wire rope 23, the wire rope 23 is driven by the guide wheel 22, meanwhile, the rear body 21 is driven by the reinforcing longitudinal beam 2 to move backwards, the wire rope 23 is also pulled to be stressed backwards and upwards, the folding roof 7 is stressed forwards and backwards and moves towards the space between the tops of the front body 1 and the rear body 21 until the guide wheel 22 is clamped into the arc-shaped groove at the top of the rear body 21, at the moment, the roof telescopic rod 25 is also completely compressed and collected at the inner side of the roof sliding groove 26, and at the moment, the top end surfaces of the front body 1, the folding roof 7 and the rear body 21.
Referring to fig. 5, 8 and 9, at the same time, the distance between the front vehicle bottom plate 30 and the rear vehicle bottom plate 15 is gradually opened, the threaded shaft 17 and the rear vehicle door shaft 18 are locked and synchronously screwed outwards, the folding vehicle door 6 and the folding doorsill 5 are screwed outwards by 90 degrees subsequently to the vehicle door shaft 18, and the threaded shaft 17 stops rotating; the hydraulic telescopic rod 16 on the front chassis 30 pushes the folding bottom plate 3 and the folding seat 4 on the folding bottom plate to move backwards to a position between the front chassis 30 and the rear chassis 15, and the lugs on the inner side of the folding doorsill 5 are clamped into the grooves on the end surfaces of the two sides of the folding bottom plate 3 from left to right; then, the rear door shaft 18 and the threaded shaft 17 are unlocked to be in a threaded connection state, and when the threaded shaft 17 continues to rotate, the rear door shaft 18 drives the folding door 6 and the folding doorsill 5 to move downwards, and the folding doorsill 5 drives the folding bottom plate 3 and the folding seat 4 thereon to descend together until the folding bottom plate, the front bottom plate 30 and the rear bottom plate 15 are positioned on the same plane.
At this moment, the chassis transmission motor 10 rotates reversely to drive the reinforcing longitudinal beam 2 and the rear vehicle body 21 to move forward a little, the rear vehicle bottom plate 15 moves forward, the front protrusion of the rear vehicle bottom plate is clamped in the groove 34 of the rear end face of the folding bottom plate 3, the folding bottom plate 3 continues to be pushed to move forward, the protrusion 32 of the front end face of the folding bottom plate 3 is forced to be clamped in the elastic groove 33 of the rear end face of the front vehicle bottom plate 30, and therefore limiting and supporting of the folding bottom plate 3 are completed.
Referring to fig. 7, at the same time, the fastening assembly works, the micro motor inside the front body 1 drives the front screws 24 at the top and bottom of the front body 1 to respectively rotate into the middle screw holes 35 in the folding top board 7 and the folding threshold 5, and the front screws 24 at the top and bottom of the front body 1 simultaneously drive the rear screws 28 to respectively rotate into the rear screw holes 29 at the top and bottom of the rear body; the front screw 24 in the middle of the front body 1 is rotated into the rear screw hole 29 in the middle of the rear body, thereby completing the fixation of the top, bottom, middle and the folding roof 7 and the folding doorsill 5 of the vehicle body.
Referring to fig. 2, the hydraulic machine 8 works in the whole process, and the displacement of the piston 13 caused by the movement of the reinforced longitudinal beam 2 is matched, so that the vehicle is fully extended and unfolded, the hydraulic machine 8 stops working, and the position of the reinforced longitudinal beam 2 is locked to resist the longitudinal impact force.
When the vehicle is folded and shortened: firstly, a transmission motor 10 in the chassis folding telescopic assembly rotates to drive the reinforcing longitudinal beam 2 to transversely move, and a small distance is drawn between the front vehicle body 1 and the rear vehicle body 21.
Meanwhile, the three groups of fasteners of the vehicle body work, the micro motor in the front vehicle body 1 rotates reversely, the rear screw rods 28 at the top and the bottom of the vehicle body are driven by the front screw rods 24 to respectively rotate and retract into the middle section screw holes 35 in the folding top board 7 and the folding threshold 5, the front screw rods 24 at the top, the bottom and the middle of the vehicle body simultaneously rotate and retract into the front vehicle body 1, and the threaded connection between the front vehicle body 1 and the rear vehicle body 21 and between the front vehicle body 1 and the folding top board 7 and the folding threshold 5 is released.
