Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
A kind of children trolley as shown in Figure 1, including having the vehicle frame of deployed condition and folded state, vehicle frame includes push-rod assembly
1, front strut assembly 2, rear pole assembly 3, front-wheel support assembly 4, rear wheel support assembly 5 and for vehicle frame is locked in expansion
Locking mechanism under state.
In the present embodiment: push-rod assembly 1 bottom, front strut assembly 2 upper end and rear pole assembly 3 upper end are logical
Crossing link gear to rotate connection, front strut assembly 2 bottom rotates with front-wheel support assembly 4 and is connected, rear pole assembly 3 times
End rotates with rear wheel support assembly 5 and is connected, and front-wheel support assembly 4 slides mutually with rear wheel support assembly 5
Connect.The direction that front strut assembly 2 and rear pole assembly 3 and front-wheel support assembly 4 are extended has the angle towards front, folder
Angle is respectively less than 90 degree, and the angle of front strut assembly 2 and front-wheel support assembly 4 is more than rear pole assembly 3 and front-wheel support assembly 4
Angle.
Specifically: push-rod assembly 1 includes the upper push-rod group that lower push-rod assembly 10 is slidably connected with lower push-rod assembly 10 phase
Part 11, by relative with upper push-rod assembly 11 for lower push-rod assembly 10 locking member locked, lower push-rod assembly 10 bottom and front support
Bar assembly 2 upper end and rear pole assembly 3 upper end are rotated connection by link gear.Lower push-rod assembly 10 be two hollow
Rod member, upper push-rod assembly 11 is U-shaped rod member, and what slided respectively in the two ends of the U-shaped rod member of upper push-rod assembly 11 is plugged in lower push-rod
In two hollow rod of assembly 10, it is achieved relatively slide.Locking member can be locked out mechanism's part, it is also possible to locking
Mechanism is independently arranged, and locking member, locking mechanism all can be arranged on upper push-rod assembly 11, it is simple to solve latching operation.?
In the present embodiment, locking mechanism, locking member are not primary object, and the structure that can realize above-mentioned lock function all can make
With, repeat the most one by one at this.
Front strut assembly 2, rear pole assembly 3 are respectively two rod members.
Front-wheel support assembly 4 is the U-shaped rod member connecting and having wheel, and rear wheel support assembly 5 is the hollow U-shaped connecting and having wheel
Rod member, what slided respectively in the two ends of the U-shaped rod member of front-wheel support assembly 4 is plugged in the hollow U-shaped rod member of rear wheel support assembly 5
In, it is achieved relatively slide.Slide block 40, front strut assembly 2 bottom and slide block 40 company of rotating it is provided with on front-wheel support assembly 4
Connect.
After the locking mechanism of go-cart unlocks, push-rod assembly is pressed for 1 time, under the effect of link gear, push-rod assembly 1,
Front strut assembly 2 interlocks with the rotation with rear pole assembly 3, drives front-wheel support assembly 4 during front strut assembly 2 rotates simultaneously
Rear wheel carriage assembly 5 direction slide, push-rod assembly 1, front strut assembly 2, rear pole assembly 2 front wheel carriage assembly 4 and after
Wheel support assembly 5 is drawn close, and front-wheel support group 4 rear wheel carriage assembly 5 slides and draws in, thus completes to fold, as shown in Figure 2,3.
The below embodiment of one link gear of act:
As Figure 4-Figure 6: lower push-rod assembly 10 bottom connects push rod tumbler 100, front strut assembly 2 upper end connects to be had
Front strut tumbler 20, rear pole assembly 3 upper end connects rear pole tumbler 30, and push rod tumbler 100, front strut rotate
Part 20 and rear pole tumbler 30 are rotated connection by the first axle 64.
Link gear includes being opened in the first arcuate groove 60 on push rod tumbler 100, is opened on front strut tumbler 20
The second arcuate groove 61, the straight-line groove 62 being opened on rear pole tumbler 30 and sliding shoe 63, the first arcuate groove 60 is from upper
And the distance down and between the first axle 64 becomes larger, second arcuate groove 61 distance from top to bottom and between the first axle 64 is gradually
Diminishing, the straight-line groove 62 distance from top to bottom and between the first axle 64 tapers into, and sliding shoe 63 offers axis hole 630, edge
The chute 631 that its length direction extends.First axle 64 is through the chute 631 of sliding shoe 63；One second axle 65 is also cross first
Arcuate groove the 60, second arcuate groove 61, straight-line groove 62 and the axis hole 630 of sliding shoe 63, the second axle 65 can be at the first arcuate groove
60, slide in the second arcuate groove 61, straight-line groove 62.When promoting push-rod assembly 1, push rod tumbler 100 rotates, and first
The second axle 64 in arcuate groove 60 slides, and by the drive of sliding shoe 63, the second axle 64 is at the straight-line groove of rear pole tumbler 30
62, the second arcuate groove 61 inter-sync of front strut tumbler 20 is slided, thus drives front strut assembly 2, rear pole assembly 3 to synchronize
Rotate, it is achieved the linkage of rotation.The structure of link gear is not limited to this, it is possible to the structure realizing this linkage function all can make
With, repeat the most one by one at this.
Additionally, the junction of push-rod assembly 1 bottom, front strut assembly 2 upper end and rear pole assembly 3 upper end sets
Being equipped with roll-shell 7, link gear is arranged in roll-shell 7.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
