Description

two-way folding baby stroller

technical field

The utility model relates to a baby stroller, in particular to a two-way folding baby stroller.

Background technique

Baby strollers are already a necessary tool for infants and young children to travel. In addition to pursuing the basic requirements of stability and safety of baby strollers, users pay more and more attention to the characteristics of small size, light weight, and foldable baby strollers. The baby stroller with the above characteristics can easily prevent it from being stuck in the trunk of the car, and it can also reduce the volume it occupies on the bus or train, which greatly facilitates travel and portability.

Existing strollers usually include a vehicle frame, a front wheel assembly, and a rear wheel assembly. The vehicle frame includes two side frames arranged symmetrically on the left and right and a plurality of cross bars connected between the two sides of the frame. Each side frame Including front bracket, rear bracket and push rod, the frame can be locked when unfolded for use. However, the structures of the existing two-way folding carts are relatively similar, not novel enough, and the folded volume is still relatively large, which is inconvenient for storage and carrying.

The specific structure of the rear bracket folding strut assembly is as follows: the rear bracket folding strut assembly includes an X-shaped strut formed by pinning the middle parts of two struts, and a X-shaped strut that is pinned to the four ends of the X-shaped strut. The two end connectors located above the X-shaped strut are rotatably connected to the rear bracket, and the two end connectors located below the X-shaped strut are rotatably connected to the sliding sleeve on the rear bracket.

In order to facilitate the unlocking of the sliding sleeve by the first locking mechanism, the locking structure of the first locking mechanism is located inside the rear bracket, and its corresponding unlocking structure is arranged on the push rod.

When the frame is folded, release the locking of the first locking mechanism and the second locking mechanism, lift up the push rod to fold the pin joint in the middle of the strut assembly and press down the push rod, and the sliding sleeve is driven down along the rear bracket by the support rod. Move, the rear end of the front bracket moves down with the sliding sleeve. At this time, the push rod, the rear bracket, and the front bracket are relatively folded. When the above-mentioned frame is retracted longitudinally, the push rod folds the strut assembly and the rear bracket folds the strut. Under the action of the assembly, the support rod folding strut assembly, the front bracket folding strut assembly and the bottom support rod, the vehicle frame is folded horizontally, thereby completing the folding of the entire vehicle.

The utility model has the advantages of:

1. The structure of the utility model is relatively novel. It can not only be folded back and forth, but also can be folded left and right. The folded volume is smaller, and it is more convenient to store and carry.

2.
