Angle is 80-90 °）.
Further, the rear portion of seat bar 120 is fixedly connected or is wholely set with after-poppet 12（In this example, seat bar 120 is by rear
12 upper end forward fold of stent simultaneously extends to form）, forepart and the fore-stock 11 of seat bar 120 are rotatedly set.In addition, linking support
The top of 13 upper end of bar and fore-stock 11 is rotatablely connected, after-poppet 12 can be slided along the length extending direction of linking support bar 13 and
The setting rotated relative to linking support bar 13；Specifically, the sliding part 4 that can be slided along its length is provided on linking support bar 13
（In this example, sliding part 4 is the sliding sleeve being set on fore-stock）, after-poppet 12 is rotatablely connected with sliding part 4, i.e. after-poppet
12 realize the connection relation slided and rotate with linking support bar 13 by sliding part 4.When stroller frame is respectively at expansion shape
When state and folded state, after-poppet 12 is connected to the first position W1 of linking support bar 13 and second position W2, first position W1
Positioned at the lower part of linking support bar 13（See Fig. 1）, second position W2 is located at the upper end close to linking support bar 13 on linking support bar 13
（See Fig. 4）.
In addition, as shown in Figure 1 and Figure 2, the front end of this example midsole support 2, rear end portion respectively with the lower part of fore-stock 11 and
After-poppet 12 is rotatablely connected, and back pole-bracket 3 is located between the after-poppet 12 of both sides, and is rotatablely connected with the after-poppet 12 of both sides；Tool
Body：Back pole-bracket 3 includes：Middle bar 30, middle bar 30 extend along cart vertical direction；First upper connecting rod 31 and the second upper connecting rod 32,
One end of first upper connecting rod 31 and the second upper connecting rod 32 respectively with the upper end of middle bar 30 be rotatablely connected, the other end respectively with both sides
After-poppet 12 be rotatablely connected；The one of first lower link 33 and the second lower link 34, the first lower link 33 and the second lower link 34
The lower rotational respectively with middle bar 30 is held to be connected, the other end is rotatablely connected respectively with the after-poppet of both sides 12；Sliding block 35, along
The extending direction of middle bar 30 can be slidably arranged on middle bar 30；First diagonal control arm 36, the second diagonal control arm 37, the first diagonal control arm
36th, the lower end of the second diagonal control arm 37 is rotatablely connected respectively with the first lower link 33 and the second lower link 34,35 turns of upper end and sliding block
Dynamic connection（In this example, back pole-bracket 3 is provided with the knob for being used to pull 3 folding of back pole-bracket for being fixedly connected on middle 30 bottom end of bar
38）.Bottom bracing frame 2 is cross structure bottom bracing frame 2, including intersecting and the first bottom bar 21 and for the connection that rotates in infall
The forepart of two bottom bars 22, the first bottom bar 21 and the second bottom bar 22 is rotatablely connected respectively with the fore-stock of both sides 11；First bottom bar 21
It is rotatablely connected respectively with the after-poppet of both sides 12 with the rear portion of the second bottom bar 22.
As shown in Figure 1, when stroller frame is under unfolded state, locking mechanism locking frame, fore-stock 11 and after-poppet
12 are mutually unfolded and are stood on the ground by front component 100 and the support of wheel assembly 200 respectively, and after-poppet 12 and its upper end are consolidated
Surely the seatpost 120 connected is mutually unfolded with fore-stock 11, linking support bar 13；The junction of seat bar 120 and fore-stock 11, linking support bar 13
With 12 junction of after-poppet（In first position W1）It is located at linking support bar 13 and the front lower place of 11 junction of fore-stock, linking support respectively

Angle between is 80-90 °.
With reference to Fig. 1 to Fig. 4, when stroller frame folds, locking mechanism unlock catches the knob 38 on back pole-bracket 3 upward
Movement, the middle bar 30 of back pole-bracket 3, which moves upwards, drives 3 each component of back pole-bracket to draw close folding, i.e. band from two lateral centres of vehicle frame
The after-poppet 12 of dynamic both sides is drawn close from two lateral centres of vehicle frame, and drives the other component in bottom bracing frame 2 and side stand 1 in
Between draw close, the knob 38 on catching back pole-bracket 3 move upwards drive after-poppet 12 drawn close to centre while, also can be to rear branch
The lower end of frame 12 applies the power overturn rearwardly and upwardly, i.e. seatpost 120（Seatpost is the same part with after-poppet）It can be opposite
Fore-stock 11 rotates, since after-poppet 12 is to rotate being connected on linking support bar 13 of sliding again, then 12 turns of after-poppet
It, can be along 13 upward sliding of linking support bar when dynamic（Second position W2 is slided to always, and interference is generated to avoid to folding）, i.e. after-poppet
12 and its seatpost 120 of upper end gradually rotate and draw close with fore-stock 11, so far, that is, complete the folding process of entire cart,
Vehicle frame is converted to folded state.
As shown in figure 4, stroller frame is under folded state, front component 100, wheel assembly 200 prolong along fore-stock 11
Direction is stretched to be located remotely from each other；Each rod piece extends along 11 extending direction of fore-stock and on a left side in side stand 1, bottom bracing frame 2, back pole-bracket 3
Right direction close proximity.
To sum up, the children trolley of the utility model, compared to traditional cart, after-poppet and seatpost its be bent into for a bar
Type, a bar have had both the after-poppet of traditional cart and the function of seatpost, and rod piece is reduced, and decreases vehicle frame folding process rod piece
Between interference situation, and cause after cart the past left and right directions that can realize that one carries and rolls over using bottom bracing frame and back pole-bracket, folding
Poststack, vehicle body is slender, and close proximity and carefully and neatly done arrangement, small between each component, is particularly suitable in long and narrow space storage；This
Outside, front component is mounted on to the bottom of push rod, push rod is made to have had both the function of front-wheel support in traditional cart, cart is whole
Rod piece is further reduced, and avoids the excessive connection relation between excessive rod piece；By linking support fore-stock and after-poppet it
Between linking support bar so that vehicle frame keeps rigidity well, and overall structure is more firm, after bearing a heavy burden will not in receive.
The utility model is described in detail above, its object is to allow the personage for being familiar with this field technology can be much of that
It solves the content of the utility model and is carried out, the scope of protection of the utility model, and the utility model can not be limited with this
The above embodiments are not limited to, the equivalent change or modification that all Spirit Essences according to the present utility model are made should all cover
Within the scope of protection of the utility model.
