Stroller

A folding stroller having a frame that can be arranged in at least a first configuration and a second configuration, the frame comprising:

• a handgrip fixedly connected to an upper joint;
• a lower joint pivotally connected to the upper joint, the lower joint being fixedly connected to a front tube;
• a rear joint pivotally connected to the lower joint, the rear joint being fixedly connected to a rear tube;
• and
• a joint connecting rod connected to the lower joint, the rear joint, and the upper joint;
• wherein a distance between the upper joint and the rear joint is larger than a predefined threshold while the frame is in the first configuration, while the frame is in the second configuration, and while the frame is transitioning between the first configuration and the second configuration.

A folding stroller having a frame, the frame being foldable between a folded configuration and an unfolded configuration, the frame comprising:

• a handgrip, a front tube, a rear tube and a joint assembly,
• the joint assembly comprising an upper joint, a rear joint, a lower joint and a joint connecting rod;
• an upper end of the upper joint being fixedly connected with the handgrip, and the upper joint being provided with a first pivot point and a second pivot point;
• a lower end of the rear joint being fixedly connected with the rear tube, and the rear joint being provided with a third pivot point and a fourth pivot point;
• the lower joint being fixedly connected with the front tube, and the lower joint being provided with a fifth pivot point and a sixth pivot point;
• a first pivot shaft passing through the fifth pivot point and the first pivot point, the first pivot shaft pivotally connecting the lower joint with the upper joint;
• a second pivot shaft passing through the sixth pivot point and the fourth pivot point, the second pivot shaft pivotally connecting the lower joint with the rear joint;
• wherein the opposite ends of the joint connecting rod are configured to be pivoted on the second pivot point and the third pivot point respectively,
• wherein, while the frame transitions between the folded configuration and unfolded configuration, the handgrip causes the upper joint to rotate about the first pivot shaft, and the joint connecting rod is able to cause the rear joint and the rear tube to rotate about the second pivot shaft causing the rear tube to approach or move away from the front tube.
