Claim:
A playpen hub assembly comprising: a base having a base body, wherein a first rail is formed on the base and the base comprises: a slider movably disposed in the first rail for moving between a lock position and a release position along the first rail; and a driving part connected to the slider; a first support part pivoted to a side of the base; and a second support part pivoted to another side of the base; wherein one end of the slider has a first block structure for constraining rotation of the first support part relative to the base body, another end of the slider has a second block structure for constraining rotation of the second support part relative to the base body, and the driving part is used for driving the first block structure and the second block structure of the slider to move to the release position in one direction along the first rail so as to release restriction of the first block structure for the first support part and restriction of the second block structure for the second support part; when the slider is located at the lock position, the first rail is substantially parallel to the first support part and the second support part.
