In the present embodiment, because housing 32 only is more smooth and easy between assistance body of rod interlock, housing 32 also can omit, or fore shell portion 321 or back cover portion 322 are only arranged.
At last, as shown in Figure 1, the right-hand member of right side second pole 13, the right-hand member of right side the 3rd pole 14, the left end of left side the 5th pole 23 and the left end of left side the 6th pole 24 are articulated in center rod 71 together.
By above assembling, accomplish the double seat infant car frame of the present invention's first preferred embodiment.
Vehicle frame fold operation
It is to fold by a side stand unit (second carrier unit 20) that the present invention designs main concept, drives opposite side carrier unit (first carrier unit 10) and folds synchronously, when launching operation also is.
When desiring to fold vehicle frame (this moment, vehicle frame was in deployed condition shown in Figure 3); Swing handle 251 is so that locking type retracting mechanism 25 unblanks to make pedestal 252 and slide 253 no longer locking each other; Can spur guide rod 255 and move up this moment; And interlock guide rod 255 rotation and then upwards draw, pedal base 254 moves up in company with handle 251 and guide rod 255, folds so that each pole 22,23,24 of second carrier unit 20 pivots.Extremely shown in Figure 7 like Fig. 5; Borrowing the interlinked mechanism 30 that is connected between first carrier unit 10 and second carrier unit 20; Along with the pivot of each pole 22,23,24 of second carrier unit 20 folds; After left side the 4th pole 22 upwards pivoted with respect to second articulated part 52, the 4th articulated part 54 can move along second horizontal concrete chute 334, and interlock dish 33 is moved with respect to housing 32 or center rod 71; Drive simultaneously that the 3rd articulated part 53 moves in first horizontal concrete chute 333 on first carrier unit 10, make first mobile jib 11, center rod 71 and second mobile jib 21 each other near and accomplish folding of vehicle frame.
The expansion operation of vehicle frame
When desire is launched vehicle frame (this moment, vehicle frame was in collapse state shown in Figure 4), can be hand steered center rod 71, the foot pedal seat 254 then; Each pole 22,23,24 of second carrier unit 20 is pivoted,, each pole 12,13,14 of first carrier unit 10 is pivoted by the drive of interlinked mechanism 30; Make first mobile jib 11, center rod 71 and second mobile jib 21 each other away from; Slide 253 moves up along guide rod 255, last and pedestal 252 lock in place, and keep the vehicle frame deployed condition.
Second preferred embodiment
The structure of vehicle frame and assembling
As shown in Figure 8, the double seat infant car frame of the present invention's second preferred embodiment comprises one first carrier unit 10, one second carrier unit 20 and an interlinked mechanism 60.
Interlinked mechanism is a trace 62.The two ends of trace 62 respectively have a pivoted hole 625.
The assembling of interlinked mechanism
As shown in Figure 8; The right-hand member of right side first pole 12 and the left end of left side the 4th pole 22 are articulated in center rod 71 together; The left end of the left end of the right-hand member of the right-hand member of right side second pole 13, right side the 3rd pole 14, left side the 5th pole 23 and left side the 6th pole 24 is articulated in center rod 71 together, and two pivoted holes 625 that pass trace 62 with two articulated parts 55 then are pivoted to the pivoted hole 145 of right side the 3rd pole 14 and the pivoted hole 225 of left side the 4th pole 22 respectively.
In the present embodiment, trace 62 can also be pivoted to right side first pole 12 and left side the 6th pole 24, or is pivoted to right side first pole 12 and left side the 5th pole 23, as long as be pivoted to the pole of different support unit.That is to say, if trace 62 is pivoted to the 4th pole 22 and the 3rd pole 14, then be that connecting rod up draws another pole reaching to fold purpose, and if be pivoted to first pole 12 and the 6th pole 24, then be under the drive of a pole, up to push away another pole.
Borrow above assembling, accomplishing the double seat infant car frame of the present invention's second preferred embodiment.
Vehicle frame fold operation
Like Figure 10 and shown in Figure 11, (this moment, vehicle frame was in deployed condition shown in Figure 9) operates with the mode of folding of identical as first embodiment when desiring to fold vehicle frame, folds so that each pole 22,23,24 of second carrier unit 20 pivots.Simultaneously; Borrowing the interlinked mechanism 60 that is connected between first carrier unit 10 and second carrier unit 20; Along with the pivot of each pole 22,23,24 of second carrier unit 20 folds, trace 62 upwards spurs right side the 3rd pole 14, folds so that first carrier unit 10 pivots linkedly; Make first mobile jib 11, center rod 71 and second mobile jib 21 each other near, and then accomplish folding of vehicle frame.
The expansion operation of vehicle frame
When desire is launched vehicle frame (this moment, vehicle frame was in collapse state shown in Figure 11); Likewise, with hand steered center rod 71, the foot pedal seat 254 then; This moment, slide 253 upwards slided with respect to guide rod 255; First carrier unit 10 and second carrier unit 20 launch simultaneously, make first mobile jib 11, center rod 71 and second mobile jib 21 each other away from, and then accomplish the expansion of vehicle frame.
But above-describedly be merely preferred embodiment of the present invention; When not limiting the scope that the present invention implements with this; Be that all simple equivalent of being done according to application right claimed range of the present invention and description of the invention content change and modify, all should still belong in the scope that patent of the present invention contains.
