Automatically foldable tent frames and mechanisms for automatically folding and unfolding tent frames

摘要

A tent frame includes supporting poles and an upper frame connected to the supporting poles. The upper frame includes a guide pole, first and second connectors, upper connecting units, and a driving mechanism. The first and second connectors are coupled with the guide pole. Each upper connecting unit includes one or more upper pole pairs. Each upper pole pair includes two upper poles pivotally connected to each other and forming an “X” shape when unfolded. Of the upper pole pair proximal the guide pole, one upper pole is pivotally connected to the first connector and the other upper pole is pivotally connected to the second connector. The driving mechanism includes a motor for moving one or both of the first and second connectors along the guide pole, a power source for providing power to the motor, and a controlling device for controlling the motor.
