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.
As shown in Fig. 1, Fig. 7 and Fig. 8, children trolley of the present utility model includes having and launches and the stroller frame 1 of folded state, be arranged on the anterior front component 2 in the end of stroller frame 1, be arranged on the wheel assembly 3 at the rear portion, the end of stroller frame 1, for stroller frame 1 is locked locking mechanism in the deployed state.
Stroller frame 1 includes the fore-stock 11 for installing front component 2, for installing the after-poppet 12 of wheel assembly 3, push rod 13, the one end of the one end of fore-stock 11, the one end of after-poppet 12 and push rod 13 is rotated connection by cradle head.
nullAs shown in Fig. 2 ~ Fig. 6，Cradle head includes the first connector 41、Second connector 42、3rd connector 43 and actuator 44，The one end of the first connector 41 and the one end of the second connector 42 are rotated connection by the 3rd axle 47，The one end of the 3rd connector 43 and the one end of the second connector 42 are rotated connection by the 4th axle 48，The one end of actuator 44 and the one end of the 3rd connector 43 are rotated connection by the first axle 45，The one end of the other end of actuator 44 and the first connector 41 is rotated by the second axle 46 and is connected，The other end of first connector 41 is fixedly connected with the one end of fore-stock 11，The other end of second connector 42 is fixedly connected with the one end of after-poppet 12，The other end of 3rd connector 43 is fixedly connected with the one end of push rod 13，So，First connector 41、Second connector 42、3rd connector 43、A quadric chain it is formed between actuator 44.
In the present embodiment, first connector the 41, second connector the 42, the 3rd connector 43 and actuator 44 structure the most in the form of sheets, first axle the 45, second axle the 46, the 3rd axle the 47, the 4th axle 48 be arranged in parallel, and all along the thickness direction extension of first connector the 41, second connector the 42, the 3rd connector 43 and actuator 44.
A kind of specific embodiment, the first connector 41 and the 3rd connector 43 are separately positioned on the second connector 42 both sides in a thickness direction.
Another specific embodiment, the first connector 41 and the 3rd connector 43 lay respectively in the second connector 42 the same side in a thickness direction, as shown in Figure 3.
Another specific embodiment, first connector 41 and the 3rd connector 43 have two groups respectively, two group of first connector 41 is symmetrically arranged at the both sides on the thickness direction of the second connector 42, two group of the 3rd connector 43 is symmetrically arranged at the both sides on the thickness direction of the second connector 42, as shown in Figure 4.
This cradle head also has expansion and folded state; locking mechanism is arranged at cradle head; when locking mechanism is in the lock state; cradle head is in deployed condition; locking mechanism is not the technical essential of this patent protection; structure of the prior art can be used; after locking mechanism unlocks; this cradle head can fold; during folding; as long as parts in upset first connector the 41, second connector 42 and the 3rd connector 43, remaining several parts just can be driven mutually to overturn folding by quadric chain.
3rd connector 43 is provided with the chute 431 matched with the first axle 45, length bearing of trend and the 3rd connector 43 reverses direction when the second connector 42 rotates of chute 431 are consistent, first axle 45 is located in this chute 431 and can arrange slidably along the length bearing of trend of chute 431, when the 3rd connector 43 folds to the direction upset drawn close with the second connector 42, order about the first connector 41 by above-mentioned quadric chain and also overturn folding to the direction drawing close the second connector 42, until the 3rd connector 43 is drawn close with the second connector 42, as shown in Figure 5；Press on the first connector 41 the most again, the direction making the first connector 41 continue to drawing close the second connector 42 rotates, now the first axle 45 in chute 431 along chute 431 length bearing of trend slide, until the first connector 41 is close together completely with the second connector 42, so that cradle head reaches the state that the degree of depth folds, as shown in Figure 6.Made the volume after the folding of cradle head more compact by the design of such structure, structure is less.In the present embodiment, chute 431 is waist-shaped hole, when cradle head is in deployed condition, or at the 3rd connector 43 during the direction upset drawn close with the second connector 42 folds, first axle 45 is positioned at the one end of chute 431 in chute 431, when cradle head is in degree of depth folded state, and the i.e. first connector 41 and the second connector 42 are also close together, the first axle 45 is positioned at the other end of chute 431 in chute 431.
This cradle head also includes for limiting the first connector 41, the position limiting structure of the folding position of the second connector 42 and the 3rd connector 43, position limiting structure includes the first stopper slot 421 and the second stopper slot 422 being separately positioned on the second connector 42, first stopper slot 421 matches with the first axle 45, second stopper slot 422 matches with the second axle 46, first axle 45 is located in the first stopper slot 421, second axle 46 is located in the second stopper slot 422, when relative second connector 42 upset of the 3rd connector 43 folds, first axle 45 slides in the first stopper slot 421, when relative second connector 42 upset of the first connector 41 folds, second axle 46 slides in the second stopper slot 422.A kind of specific embodiment, when cradle head is in deployed condition, first axle 45 is positioned at the one end on the length direction of the first stopper slot 421 in the first stopper slot 421, second axle 46 is positioned at the one end on the length direction of the second stopper slot 422 in the second stopper slot 422, when cradle head is in degree of depth folded state, first axle 45 is positioned at the other end on the length direction of the first stopper slot 421 in the first stopper slot 421, and the second axle 46 is positioned at the other end on the length direction of the second stopper slot 422 in the second stopper slot 422.
When locking mechanism is in the lock state, children trolley is in deployed condition, as shown in Figure 1.
When this children trolley folds, first unlock locking mechanism, pressure push rod 13 down, drive fore-stock 11 to turn over by the quadric chain of cradle head during push rod 13 downwardly turns over and draws close with after-poppet 12 and after-poppet 12 is drawn close, after push rod 13 is together with after-poppet 12 close proximity, fore-stock 11 also has a certain degree of drawing close with after-poppet 12, as shown in Figure 7, then, fore-stock 11 is made to turn over further at the direction pressing fore-stock 11 drawn close to after-poppet 12, now, first axle 45 slides in chute 431, until fore-stock 11 is together with after-poppet 12 also close proximity, as shown in Figure 8, now children trolley is in degree of depth folded state, make the children trolley compact conformation after folding, small volume.In the folding process of whole children trolley, front component 2 and wheel assembly 3 support all the time and stand on ground so that the folding of children trolley is very convenient, and is easy to deposit.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
