Description

Technical Field

[0001] This utility model belongs to the field of children's stroller technology, and relates to a children's stroller frame structure and a children's stroller. Background Technology

[0002] In the present technology, children's strollers are often foldable for easy carrying and storage. There are many types of existing children's strollers, with different numbers of stroller frame members and different connection positions between the members, resulting in different folding principles and methods, and different effects after folding.

[0003] For example, an invention patent with application number CN202311866864.7 provides a children's stroller, including a frame with an unfolded position and a folded position, a locking mechanism, and multiple wheel assemblies. The frame includes a rear wheel bracket, a front wheel bracket, a push rod bracket, a rear support bracket, and a lower linkage. A first linkage mechanism is formed between the rear support bracket, the push rod bracket, and the rear wheel bracket, and a second linkage mechanism is formed between the rear support bracket, the rear wheel bracket, the front wheel bracket, and the lower linkage.

[0004] In summary, although some existing technical solutions can control the two linkage mechanisms to operate synchronously when the rear support frame rotates around the three axes relative to the rear wheel bracket, that is, the push rod frame and the front wheel bracket move away from the rear wheel bracket or move towards the rear wheel bracket simultaneously to realize the unfolding or folding of the frame, there is no corresponding linkage effect with the handlebar. In other words, the frame cannot be folded directly through the handlebar, which has considerable room for improvement. Summary of the Invention
