Detailed description of the invention
With specific embodiment, the technical solution of the utility model is further elaborated below in conjunction with the accompanying drawings.
Seeing the children trolley shown in Fig. 1 to Fig. 7, it includes having deployed condition and the vehicle frame of folded state, be located at car
Wheel assembly bottom frame, and for vehicle frame is locked locking mechanism in the deployed state.Vehicle frame includes fore-stock 1, props up afterwards
Frame 2, seat bar 3, push rod 4 and strut 5, wherein, fore-stock 1 and after-poppet 2 intersect setting, and pivotally connected on after-poppet 2 have cunning
Moving part, this sliding part can slide up and down to be located on fore-stock 1 along the length bearing of trend of fore-stock 1；Seat bar 3 is along the longitudinal direction
Extending, the front portion of seat bar 3 is connected with the top phase pivot of after-poppet 2, and the pivot connection point between seat bar 3 and after-poppet 2 should
It is positioned at the top of above-mentioned sliding part；The top these three parts of the bottom of push rod 4, the rear portion of seat bar 3 and fore-stock 1 relatively rotate
Ground connects, and concretely two parts phase pivots in these three parts connect, in the 3rd parts and both of the aforesaid parts
One parts phase pivot connects；Strut 5 is vertically extending, and its upper end is pivotally connected on push rod 4, and its lower end is pivotally connected
On after-poppet 2.
Wheel assembly includes being located at the front-wheel 20 at two ends, left and right bottom fore-stock 1, is located at bottom after-poppet 2 behind two ends, left and right
Wheel 30, locking mechanism can be located between sliding part and fore-stock 1 for both being locked.When vehicle frame launches, institute as shown in Figure 1, Figure 2
Showing, intersecting between fore-stock 1 and after-poppet 2 and stand in ground by front-wheel 20 and trailing wheel 30 support, seat bar 3 is along the longitudinal direction
Extending, strut 5 stands between push rod 4 and after-poppet 2 in rear side support.When vehicle frame folding, locking mechanism unlocks, and push rod 4 is backward
Upset and sliding part are along fore-stock 1 slide downward, so that fore-stock 1, after-poppet 2, seat bar 3, push rod 4 and strut 5 are mutual
Draw close, as shown in Fig. 3, Fig. 4 and Fig. 6, Fig. 7.
Seeing shown in each accompanying drawing, in the present embodiment, fore-stock 1 includes laying respectively at the front support rod 11 of the left and right sides, consolidating
Surely the front rail 12 being connected between both sides front support rod 11.After-poppet 2 includes laying respectively at the back stay 21 of the left and right sides, fixing
The rear transverse rod 22 being connected between both sides back stay 21, vehicle frame also includes bar 8, and this bar 8 is in downward opening U-shaped
Type, the two ends of bar 8 are respectively fixedly connected to the upper end of both sides back stay 21, or rear of this bar 8 and both sides
The one-body molded setting of bar 21.Push rod 4 is in downward opening U-shaped, and seat bar 3 and strut 5 have two respectively, lay respectively at vehicle frame
The left and right sides.
In the present embodiment, sliding part use for sliding sleeve 6, on the left and right sides of vehicle frame, equal pivot company on back stay 21
Being connected to sliding sleeve 6, this sliding sleeve 6 slides up and down to be set on this side front support rod 11.The front portion of seat bar 3 and the top phase of back stay 21
Pivotally connected, the bottom of the top of front support rod 11, the rear portion of seat bar 3 and push rod 4 is connected by same rotating shaft 9 phase pivot；Strut 5
Support stands between back stay 21 and a side lever portion of push rod 4.Locking mechanism includes being located between sliding sleeve 6 and front support rod 11 for inciting somebody to action
The locking piece (not shown) of both lockings, can arrange the solution that can simultaneously unlock both sides locking piece between the locking piece of both sides
Lock carry hand, so, operator only needs lifting to unlock carry hand, and after part to be locked unlocks, push rod 4 turns under self gravitation automatically backward
Turn, and drive the upper end of front support rod 11 up and sliding sleeve 6 is relatively glided along front support rod 11, as shown in Figure 3, Figure 4, so
Just each rod member is made to relatively rotate and gradually draw in together, it is achieved one carries and i.e. rolls over.Go-cart after folding as shown in Figure 6, Figure 7,
The front support rod 1 of the same side, back stay 2, seat bar 3, push rod 4 and strut 5 are the most closely close together, and front-wheel 20 is with trailing wheel 30 also
Being close together, overall volume is less, is highly susceptible to receiving and carrying.
This children trolley also includes shock absorbing apparatus 7, and this shock absorbing apparatus 7 is located on fore-stock 1.See shown in each accompanying drawing, front
Support 1 is provided with, after locking at locking mechanism, the amplitude that slides up and down of sliding sleeve 6 is carried out spacing position limiting structure, so that
Locking mechanism locked after, sliding sleeve 6 still can carry out small size cunning relative to fore-stock 1 under the restriction amplitude of above-mentioned position limiting structure
Dynamic.Specifically, on the left and right sides of vehicle frame, locking piece at least includes lock pin (not shown), before position limiting structure is for being opened in
Waist type stopper slot 13 on pole 11, when locking mechanism locks, the lock pin of locking piece can slide up and down to be plugged in above-mentioned limit
In the groove 13 of position.
Shock absorbing apparatus 7 includes vibration damping spring 71, and this vibration damping spring 71 can be set on front support rod 11 elastic telescopic.Specifically,
The top of front support rod 11 is provided with annular flange flange 14, and the upper end of vibration damping spring 71 is kept out in annular flange flange 14；The lower end of vibration damping spring 71
Being fixedly provided with baffle ring 72, this baffle ring 72 can slide up and down to be set on front support rod 11, between front support rod 11 and baffle ring 72 also
It is provided with the amplitude that baffle ring 72 is slided up and down and carries out spacing baffle ring limit assembly.Here, shown in Figure 5, this baffle ring limits
Hyte part includes the waist type stopper slot 2 15 being opened on front support rod 11, the backing pin 73 being located on baffle ring 72, and backing pin 73 can be upper and lower
It is plugged in slidably in above-mentioned stopper slot 2 15.
So, when vehicle frame is locked in deployed condition and is in smooth-riding surface, vibration damping spring 71 is in baffle ring 72 and annular flange flange
14 spacing lower and front support rod 11 relatively is fixed, should have between upper surface and the lower surface of baffle ring 72 of sliding sleeve 6 less between
Gap, or be affixed tactile between the two and there is not mutual active force.
When go-cart travels on irregular road surface, front-wheel 20 and trailing wheel 30 act on fore-stock 1 and after-poppet 2, make
Obtain sliding sleeve 6 along front support rod 11 upwards small amplitude slip so that sliding sleeve 6 is upwards kept out baffle ring 72 and compressed vibration damping spring 71, or by keeping away
Shake the elastic force of spring 71 self and promote sliding sleeve 6 vibration damping spring 71 to be released, the most just along front support rod 11 slide downward
Vehicle frame can be provided with cushion effect, reduce jolting when go-cart travels on roughness pavement, thus the use improving go-cart is comfortable
Degree.
To sum up, children trolley of the present utility model, its rod member quantity is few, simple in construction, outward appearance the most very succinct, folds
Operation is the easiest with launching, and can realize one and carry and i.e. roll over, and the volume after folding is the least, and daily the carrying for user carries with storage
Supply great convenience.Additionally, be provided with shock absorbing apparatus 7 in this go-cart, it has good shock-proof effect, substantially increases and push away
The comfort of car.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it
In.
