Example 2
Embodiment 2 changes the folding telescopic part of the vehicle body from the position behind the rear axle to the front of the rear axle in embodiment 1, is suitable for a front-drive vehicle, and is suitable for a rear-drive vehicle without a transmission shaft, and the overall performance can be improved by adjusting the wheelbase and the front-rear weight ratio of the vehicle while folding the telescopic vehicle body;
The differences from this example 1 are mainly: compared with the embodiment 1, the mounting positions of the chassis telescopic folding related components are exchanged in front-rear positions, as shown in fig. 12, the reinforcing beam 11 is mounted at the bottom of the front chassis base plate 30, and other chassis telescopic folding related components are mounted at the bottom of the rear chassis base plate 15, and correspondingly adjusted in the specific implementation direction; the folding bottom plate moves backwards instead of moving forwards after ascending, so that the folding seat (the second row of seats) is driven to be placed behind and below the third row of seats; the folding top is just as folded, but does not translate forward when folded, but is placed on the floor behind the first row of seats in situ; the folding door is disposed on the floor behind the first row of seats next to the folding top in the same manner as the folding threshold. Please refer to fig. 11, 12 and 13.
The working principle and the using flow of the invention are as follows: when the vehicle stretches and expands, referring to fig. 2, firstly, the output end of the transmission motor 10 drives the driving disc 14 to rotate, the driving disc 14 penetrates through a reserved through groove on the mounting base 9 and drives the rotating tube 12 to perform circular motion through an annular protrusion matched with an annular groove on the surface of the rotating tube 12, meanwhile, the protrusion on the inner wall of the mounting base 9 is in limit clamping with the annular groove on the surface of the rotating tube 12, the transverse position of the rotating tube 12 is guaranteed not to change, and meanwhile, the rotating tube 12 is in threaded connection with the reinforcing longitudinal beam 2, so that the reinforcing longitudinal beam 2 performs transverse motion on the inner side of the rotating tube 12.
At the same time, three sets of fasteners of the vehicle body are operated, the front screw 24 is retracted into the front vehicle body 1, and the threaded connection between the front vehicle body 1 and the rear vehicle body 21 is released.
Referring to fig. 6, a small motor on the roof of the front vehicle body 1 drives a rotating wheel 27 to wind up the steel wire rope 23, the steel wire rope 23 is driven by a guide wheel 22, meanwhile, the rear vehicle body 21 is driven by the reinforced longitudinal beam 2 to move backwards and upwards, the steel wire rope 23 is also pulled to bear force backwards and upwards, the folding roof 7 bears force forwards and backwards and moves towards the space between the front vehicle body 1 and the top of the rear vehicle body 21 until the guide wheel 22 is clamped into an arc groove at the top of the rear vehicle body 21, at the moment, the roof telescopic rod 25 is also fully compressed and stored inside the roof chute 26, and at the moment, the front vehicle body 1, the folding roof 7 and the top surface of the rear vehicle body 21 are all in the same plane.
Referring to fig. 5, 8 and 9, at the same time, the distance between the front floor 30 and the rear floor 15 is gradually pulled apart, the screw shaft 17 is locked with the rear door shaft 18, the folding door 6 and the folding threshold 5 are synchronously rotated outward, and then the door shaft 18 is rotated outward by 90 degrees to be in the same direction as the vehicle body, and the screw shaft 17 is stopped rotating; the hydraulic telescopic rod 16 on the front vehicle bottom plate 30 pushes the folding bottom plate 3 and the folding seat 4 on the folding bottom plate to move backwards between the front vehicle bottom plate 30 and the rear vehicle bottom plate 15, and the convex blocks on the inner side of the folding threshold 5 are clamped into the grooves on the end surfaces on 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 and are in a threaded connection state, and in the process of continuing to rotate the threaded shaft 17, the rear door shaft 18 drives the folding door 6 and the folding threshold 5 to move downwards, and the folding threshold 5 drives the folding bottom plate 3 and the folding seat 4 thereon to descend together until the folding bottom plate is in the same plane with the front bottom plate 30 and the rear bottom plate 15.
At this time, the chassis driving motor 10 is reversed to drive the reinforcing longitudinal beam 2 and the rear vehicle body 21 to move forward by a small amount, the rear vehicle bottom plate 15 moves forward, the front protrusions thereof are clamped into the grooves 34 of the rear end face of the folding bottom plate 3, and the folding bottom plate 3 is pushed forward continuously, so that the protruding blocks 32 of the front end face of the folding bottom plate 3 are forced to be clamped into the elastic grooves 33 of the rear end face of the front vehicle bottom plate 30, and therefore, the limiting and supporting of the folding bottom plate 3 are completed.
Referring to fig. 7, at the same time, the fastening assembly is operated, and the micro motor in the front vehicle body 1 drives the front screws 24 at the top and bottom of the front vehicle body 1 to rotate into the middle screw holes 35 in the folding top 7 and the folding threshold 5, respectively, and the front screws 24 at the top and bottom of the front vehicle body 1 simultaneously drive the rear screws 28 to rotate into the rear screw holes 29 at the top and bottom of the rear vehicle body, respectively; the front screw 24 in the middle of the front body 1 rotates into the rear screw hole 29 in the middle of the rear body, thereby completing the fixation of the top, bottom, middle and folding top 7 and folding threshold 5 of the body.
Referring to fig. 2, the hydraulic machine 8 is operated in full travel, in coordination with the displacement of the piston 13 due to the movement of the reinforcing stringers 2, so far the vehicle is extended and deployed completely in place, the hydraulic machine 8 is stopped, the position of the reinforcing stringers 2 is locked, and the longitudinal impact force is resisted.
