Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
Referring to Fig. 1 to Fig. 3, this utility model provides a kind of trailing wheel retractor device on folding electric-tricycle,
The first vehicle body frame 2 being hinged including headstock frame 1 and headstock frame 1 and the second vehicle body frame 3 being hinged with the first vehicle body frame 2,
Second vehicle body frame 3 two sides of tail is all provided with trailing wheel 4, and the second vehicle body frame 3 both sides are all hinged with column 5, in described second vehicle body frame 3
Both sides, portion are all provided with slide 6, and slide 6 is provided with chute 7；The tooth bar 8 suitable with chute 7 is installed on described slide 6；Described
The internal both sides of second vehicle body frame 3 are provided with the delivery wheel 9 matched with tooth bar 8, and delivery wheel 9 is positioned at below tooth bar 8；Described tooth bar 8
Between be connected by a linking arm 10；Mutually symmetrical stroke hole 11 it is respectively provided on two sides with on described linking arm 10；After described
It is connected by rear wheel support 12 between wheel 4 and the second vehicle body frame 3；It is provided with and stroke hole 11 on the upside of described rear wheel support 12 one end
Suitable roller 13；The internal both sides of described second vehicle body frame 3 are all provided with the rotating shaft 14 corresponding with tooth bar 8 position；Described turn
Axle 14 is provided with first driven gear the 15, second driven gear 16, and the first driven gear 15 is meshed with tooth bar 8；Described column 5
On be all fixed with one and fix axle 17；Described fixing axle 17 is provided with the driving gear 18 being meshed with the second driven gear 16.
Second driven gear 16 diameter is less than the first driven gear 15 diameter.
Ratio between second driven gear 16 diameter and the first driven gear diameter 15 is 1:2.
Described trailing wheel 4 is provided with suspended shock damper 19.
Described trailing wheel 4 is provided with electromagnetic brake device 20.
Using method of the present utility model is as follows:
When needing electro-tricycle is folded, swingable column 5, along with the swing of column 5, is fixed on column
Fixing axle 17 swings therewith, and driving gear 18 rotates the most therewith, and after driving gear 18 rotates, driving gear 18 will
The first driven gear 15 is driven to rotate by the second driven gear 16, owing to the first driven gear 15 is meshed with tooth bar 8,
Tooth bar 8 will start under the rotation of the first driven gear 15 along chute 7 track towards the first vehicle body frame 2 direction move
Dynamic, be located at the delivery wheel 9 below tooth bar and the movement of tooth bar 8 can be made more smooth and easy, when tooth bar 8 start mobile after, linking arm 10 is then
Can move, and on linking arm 10, be respectively provided on two sides with mutually symmetrical stroke hole 11, be located on the upside of rear wheel support one end
Roller 13 is then positioned at stroke hole 11, and therefore after linking arm 10 moves, roller 13 can be therewith in a side shifting in stroke hole 11
To opposite side, and during roller 13 moves, rear wheel support 12 starts constantly to be retracted in the second vehicle body frame 3, and drives
Trailing wheel 4 is the most close towards the direction of the second vehicle body frame 3, when roller 13 thoroughly from a side shifting in stroke hole 11 to opposite side
Time, the movement of roller 13 is limited by stroke hole 11 opposite side inwall wall, and rear wheel support 12 is with trailing wheel 4 the most no longer
Mobile.
Understanding in sum, this utility model can retract into the second vehicle body frame 3 by rear wheel support 12 makes trailing wheel 4 continuous
Close towards the second vehicle body frame 3, when the afterbody of the second vehicle body frame 3 is pressed close to trailing wheel 40 points, folding can be reduced to the full extent
After the volume of electro-tricycle, that reduces the electro-tricycle after folding occupies space, and electro-tricycle after folding is put
Put behind indoor, by increasing capacitance it is possible to increase people are at indoor activity space.
When needing to carry out restoring use to electro-tricycle, can carry out column 5 swinging reset, in column 5 swing process
In, the driving gear 18 being located on fixing axle rotates, and driving gear 18 drives first driven by the second driven gear 16
Gear 15 rotates, and along with the first driven gear 15 rotates, tooth bar 8 can reset under the first driven gear 15 drives, if
Roller 13 on the upside of rear wheel support one end moves to opposite side again from the side in stroke hole 11, and rear wheel support 12 starts towards
Two vehicle body frames 3 overhang, and after column 5 resets completely, driving gear 18 is the most no longer moved, and finally limits tooth bar 8
Mobile, thus fix rear wheel support 12.
Trailing wheel 4 is provided with suspended shock damper 19, by increasing capacitance it is possible to increase electro-tricycle shock-proof effect under steam；Trailing wheel 4
Being provided with electromagnetic brake device 20, electromagnetic brake device 20 has good emergency brake performance, it is possible to need at electro-tricycle
During emergency brake to be carried out, trailing wheel is braked by the very first time, makes electro-tricycle no longer travel, thus avoids unexpected sending out
Raw, it is ensured that the traffic safety of user of service.
