Under state, rear wheel 4 has the second working condition, and rear wheel 4 plays braking action (as shown in Fig. 2) at this time.Such as 3 institute of attached drawing
Show, vehicle frame 100 is under folded state, and rear wheel 4 is in the second working condition, and outer surface 41 and the ground of rear wheel 4 connect
Touching forms the support to entire children trolley, or forms the support to entire children trolley with ground face contact jointly with front vehicle wheel 2,
Children trolley is in the state supported oneself.
As shown in Fig. 4 to Fig. 9, in the present embodiment, which further includes connecting rod 9, and the lower end of connecting rod 9 passes through pivot
It is connect with rear-wheel connector 7, the pivot is parallel with connector shaft 72, and the upper end of connecting rod 9 is connected with driving device, driving device
It is able to drive connecting rod 9 to move up and down, while connecting rod 9 drives rear-wheel connector 7 to rotate around connector shaft 72, thus 7 band of rear-wheel connector
Dynamic rear wheel 4 is inwardly or outer side to overturn, the conversion of the first working condition and the second working condition of realization rear wheel 4 drive
Device can be a certain rod piece on cart, drive connecting rod 9 mobile by the rod piece when cart is folded；Driving device is also possible to
Hauling rope on cart, for pulling connecting rod 9 mobile.
As shown in Fig. 4 to Fig. 9, this kind of driving device includes cross bar 61, and the upper end of cross bar 61 and connecting rod 9 rotates company
It connects, 61 both ends of cross bar are equipped with sliding sleeve 62, and sliding sleeve 62 is respectively sleeved on the rear wheel support 3 of respective side, sliding sleeve 62 and rear-wheel branch
Frame 3 is mutually slidably connected along the length direction of rear wheel support 3, and connecting rod 9, rear-wheel connector 7, rear wheel support 3 and sliding sleeve 62 constitute song
Handle slide block mechanism；Sliding sleeve 62 includes that the outer sliding sleeve being fixedly connected by guiding 53 phase of pivot pin and inner sliding sleeve (are not marked in the present embodiment
Show), outer sliding sleeve is covered in 3 outer surface of rear wheel support and matched phase up and down direction is slidably connected, and inner sliding sleeve is inserted in rear wheel support 3
It is mutually slidably connected in inner cavity and with 3 inner surface of rear wheel support, linear guide groove 31 is offered on rear wheel support 3, be oriented to pivot pin 53
It can be slided in linear guide groove 31, for entering guiding when sliding up and down to sliding sleeve 62.
It is the lower end for being pressed on inner sliding sleeve that driving device, which further includes that upper end is pressed in sliding sleeve 62(the present embodiment) on
Elastic component 52, along the direction of axis line of cross bar 61 be movably disposed at the locking level 64 in 61 inner cavity of cross bar, elastic component 52
With so that sliding sleeve 62 tends to the trend moved up, the outer end of locking level 64 can be passed through on sliding sleeve 62 and rear wheel support 3
Lock hole 67 sliding sleeve 62 is locked on rear wheel support 3.
It has been rotatably coupled on the cross bar 61 of the children trolley and has trampled sole 66, this, which is trampled, is provided with arc on sole 66 and leads
To slot 68, it is provided with sliding pin 65 in the arc guide groove 68, which is connected with the inner end of locking level 64, passes through
Sole 66 is trampled in rotation, is trampled sole 66 and is able to drive sliding pin 65 and move in arc guide groove 68, while 65 band of sliding pin
Dynamic locking level 64 left and right directions in 61 inner cavity of cross bar is mobile, realizes the conversion between lock state and unlocked state.
In the present embodiment, the first working condition of the rear wheel 4 of children trolley and the second working condition conversion process are as follows:
When needing the rear wheel 4 of children trolley to convert from first the second working condition of working condition, steps on and trample sole 66, make
It is rotated around cross bar 61, tramples the rotation of sole 66 and sliding pin 65 is driven to move in arc guide groove 68, while sliding pin 65
Drive locking level 64 mobile to the close direction for trampling sole 66 until locking level 64 is detached from lock hole 67, at this point, sliding sleeve 62 exists
Along 3 upward sliding of rear wheel support under the drive of elastic component 52 of compressive state, cross bar 61 drives connecting rod 9 to move upwards, and connecting rod 9 drives
Rear-wheel connector 7 rotate, rear-wheel connector 7 drive rear wheel 4 around connector shaft 72 overturning until rear wheel 4 outer surface 41 with
Ground face contact forms the support to rear wheel support 3, so that the rear wheel 4 for completing children trolley is transformed into from the first working condition
Two working conditions.
When the rear wheel 4 of children trolley is converted from second the first working condition of working condition, steps on trample sole again
66, it is rotated about cross bar 61, tramples the rotation of sole 66 and drive sliding pin 65 mobile, while sliding pin 65 drives locking level 64
To mobile close to the direction for trampling sole 66 until locking level 64 is detached from lock hole 67, at this point, applying cross bar 61 along rear-wheel branch
The downward active force of 3 length direction of frame, sliding sleeve 62 is along 3 length direction slide downward of rear wheel support and compression elastic piece 52, simultaneously
Cross bar 61 drives connecting rod 9 to move downward, and connecting rod 9 drives rear-wheel connector 7 to rotate, and rear-wheel connector 7 drives rear wheel 4 to flip to the outside
Until the circumferential surface 42 and ground face contact of the rear wheel 4 form the support to rear wheel support 3, to complete children trolley
Rear wheel 4 be transformed into the first working condition from the second working condition.
Embodiment two:
If Figure 10 to Figure 12 is another children trolley according to the present invention, the main distinction of the embodiment and embodiment one is rear
Locking press button 8, which is provided with, on wheel connector 7 is in the first working condition or the second working condition (such as attached drawing for locking rear wheel 4
Shown in 10 and Figure 11), which does not have connecting rod 9 and driving device, and manual overturning rear wheel 4 makes rear wheel 4 in the first work
(as shown in attached drawing 10 and Figure 11) is converted between state and the second working condition.
In the embodiment, when needing the rear wheel 4 of children trolley to convert from the first working condition to the second working condition,
The lock state that locking press button 8 releases rear-wheel connector 7 is pressed, manually overturns rear wheel 4 until described around connector shaft 72
Rear wheel 4 outer surface 41 and ground face contact form the support to rear wheel support 3, then press locking press button 8 and rear-wheel connect
First 7 are locked；When the rear wheel 4 of children trolley is converted from the second working condition to the first working condition, locking press button 8 is pressed
The lock state of rear-wheel connector 7 is released, rear wheel 4 flips to the outside up to the circumferential surface 42 of the rear wheel 4 manually
The support to rear wheel support 3 is formed with ground face contact, then presses locking press button 8 and rear-wheel connector 7 is locked.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
