Problems solved by technology

[0003] The children's trailers in the prior art have a large overall structure and a high height, so the top occupies a large space, and they need to be folded when placed indoors. However, although commercially available children's trailers have a folding function, they cannot be folded. Most of the final overall structure is incomplete and needs to be folded multiple times. The folding structure is more complicated and not easy to operate

Embodiment 1

[0039] like figure 1 As shown in -8, a folding bicycle frame provided in this embodiment includes a bottom frame 1, a push rod 3, a push handle 7 and an upper side rod 4; one end of the push rod 3 and the upper side rod 4 passes through the push rod respectively The lower link 2 and the upper link 5 are connected to the chassis 1 in rotation, and the other ends of the push rod 3 and the upper rod 4 are both rotatably connected to the push handle 7, and the push rod 3 also passes through The rear support rod 6 is rotatably connected to the base frame 1; the push handle 7 is provided with a push handle button 9 for locking the push handle 7, and the rotation of the push handle 7 can drive the push rod lower link 2 The internal locking structure is unlocked; between the push rod 3 and the push rod lower link 2, between the upper rod 4 and the upper rod link 5, and between the rear strut 6 and the push rod 3 connected for rotation.

[0040] It should be pointed out that the fold...

Embodiment 2

[0064] On the basis of the first embodiment, this embodiment further provides a children's trailer, the children's trailer includes the folding frame, and also includes an outer barrier and the like.

[0065] It should be pointed out that the structure of the children's trailer has been disclosed as the prior art, and will not be repeated here.

[0066] It should also be pointed out that the children's trailer provided in this embodiment includes the foldable frame, so it has all the advantages of the foldable frame, which will not be repeated here.

[0067] It should also be pointed out that when the children's trailer of this embodiment is in use, in general, a bicycle is connected to the drawbar assembly 10 to drag the trailer forward; when there is no traction tool such as a bicycle, the drawbar assembly 10 needs to be removed. , Install the front wheel assembly in front of the folding frame, and the parent pushes the push handle 7 at the rear. At this time, the children's...

Abstract

The invention provides a folding cart frame and a child cart and relates to the technical field of non-motor vehicles. The folding cart frame and the child cart comprise a chassis, push rods, a push handlebar and upper side bars. One end of each push rod and one end of each upper side bar are rotationally connected with the chassis through a push rod lower connection rod and an upper side bar connection rod respectively, the other end of each push rod and the other end of each upper side bar are rotationally connected with the push handlebar respectively, and the push rods are further rotationally connected with the chassis through rear supporting rods. Push handlebar buttons used for locking the push handlebar are arranged on the push handlebar, and the rotation of the push handlebar can drive locking structures in the push rod connection rods to unlock. Each push rod and the corresponding push rod connection rod are rotationally connected, each upper side bar and the corresponding upper side bar connection rod are rotationally connected, and each rear supporting rod and the corresponding push rod are rotationally connected. The folding cart frame and the child cart are convenient to fold, and the folded structure is integrated.

Description

technical field [0001] The invention relates to the technical field of non-motor vehicles, in particular to a folding vehicle frame and a children's trailer.
