Specific implementation mode
Below in conjunction with the accompanying drawings and the preferred embodiment of the utility model is further described the utility model.
In the examples below, for convenience of describe, described in the definition about direction and it is left and right, upper and lower, forward and backward
For the orientation using children trolley as reference.
As shown in figs. 1-7, a kind of children trolley is present embodiments provided, children trolley includes being located at children trolley or so two
After-poppet 10, the wheel assembly 20 of side, wheel assembly 20 include trailing wheel 21, rear axle 22 and rear wheel connector 23, trailing wheel
Connector 23 includes the first connector 231 and the second connector 231, and the first connector 231 is connect with after-poppet 10, the second connection
The upper end of part 232 is rotated by shaft 30 with the first connector 231 and is connect, lower end and 22 company of rotating of rear axle
It connects, the second connector 232 tilts backwards or vertically extends from top to bottom, and wheel assembly 20 further includes that both ends connect respectively
The shock-proof spring 24 being connected on the first connector 231 and the second connector 232, shaft 30 are pushed away along children respectively with rear axle 22
The left and right directions of vehicle extends and is mutually parallel, and when children trolley remains static, is put down where shaft 30 and rear axle 22
The angle theta of face L2 and perpendicular L3 are 0 ° ~ 20 °, and when the front of trailing wheel 21 encounters barrier 40, trailing wheel 21 is to children trolley
Back upper place direction rotation（Such as the directions B of Fig. 3）, shock-proof spring 24 compressed.By such set-up mode, can both ensure
The stability of unitized frame can make incabloc function be fully demonstrated again.
In this example, the first connector 231 rotates with the second connector 232 is located at trailing wheel 21 at the rotation connection connecting
Top.
In this example, the second connector 232 includes in 2321 He of left interconnecting piece for being symmetrically respectively in 21 left and right sides of trailing wheel
The upper end of right interconnecting piece 2322, the upper end of left interconnecting piece 2321 and right interconnecting piece 2322 respectively with 231 phase of the first connector
Rotation connection, the lower end of the lower end of left interconnecting piece 2321 and right interconnecting piece 2322 respectively with 22 company of rotating of rear axle
It connects.Consolidating for the top for extending and being located at along the longitudinal direction trailing wheel 21 is provided between left interconnecting piece 2321 and right interconnecting piece 2322
Determine part 2323, the left and right sides of fixing piece 2323 be fixedly connected respectively with left interconnecting piece 2321 and right interconnecting piece 2322 or one at
Type.
Wherein, the front of fixing piece 2323, which is formed with, matches to prevent second with the lower end of the first connector 231
Shape is distinguished on the rear portion of the blocking portion 23231 that connector 232 rotates forward, the rear portion of fixing piece 2323 and the first connector 231
It is arranged in the first flange 2311 and second at having the first flange 2311 and the second flange 23232 that are oppositely arranged, shock-proof spring 24
Between flange 23232.The setting of blocking portion 23231 controls trailing wheel 21 and is rotated in limited range, i.e., the width rotated forward
It spends limited, rotates backward, there is shock-proof spring 24 to absorb external force, the mistake of trailing wheel 21 is also limited significantly while realizing shock-absorbing
It swings.
In other examples, directly phase can be respectively formed on the first connector 231 and the second connector 232
To being arranged and positioned at the first protrusion of 232 rear side of the first connector 231 and/or the second connector（It is not shown）With the second protrusion
（It is not shown）, the setting of shock-proof spring 24 is between the first protrusion and the second protrusion.Preferably, first protrusion, second protrusion and keep away
Shake spring 24 is located at the top of trailing wheel 21.
To sum up, the wheel assembly 20 of the utility model, it is simple in structure, it is easy for installation, and can realize rigid when cart is static
Property good not shock-absorbing, when cart is carried out very fast or encounters barrier 40（The object of thing movement can be hindered by referring specifically to all）When
Ability shock-absorbing, while the wheel assembly 20 of the utility model is quick on the draw, even if can realize that shock-absorbing acts on if barrier force very little,
The shock-proof effect that the barrier 40 on normally travel ground is protruded from especially for stair-step etc. is apparent, increase baby or
Comfort when children's ride-on has fabulous adaptability to real-life actual use scene.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this,
It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover the scope of protection of the utility model it
It is interior.
