A rod locking mechanism includes a central hub, a first rod component and a locking component. The first rod component is pivotally connected to the central hub. The first rod component includes an abutting portion. The abutting portion is movable between a first position and a second position when the first rod component pivots relative to the central hub. The locking component is movably disposed on the central hub. The abutting portion is located at a first side of the locking component when the abutting portion is located at the first position. The abutting portion drives the locking component to move when the abutting portion moves from the first position toward the second position, and the abutting portion abuts against a second side of the locking component opposite to the first side of the locking component when the abutting portion is located at the second position.

The present invention discloses a carrier frame (100) including a first tubular member (1), a second tubular member (2), a third tubular member (3) and a folding unit (4) including a first rod (42), a linkage rod (43), a second rod (44) and a pivot frame (41) pivoted to the second tubular member (2). The first rod (42) is pivoted to the pivot frame (41) at a first pivot point and a second pivot point respectively. The linkage rod (43) is pivoted to the first tubular member (1) and pivoted to the pivot frame (41) at a third pivot point. The second rod (44) is pivoted to the third tubular member (3) and pivoted to the linkage rod (43) at a fourth pivot point. The second, third and fourth pivot points are located at the same pivot axis. The carrier frame (100) can be released and folded synchronously and has advantages that the carrier frame (100) is easy to fold, has a simple structure, and is convenient to operate.

A stroller includes a frame, a handle, a plurality of support legs, a wheel attached to a lower end of each support leg, and a seat attached to the frame. The seat includes an internal Peltier device for selectively heating or cooling the seat. The Peltier device is powered via an onboard battery installed in an electronics housing that includes multiple USB ports. A blanket is removably secured to the seat via one or more fasteners. A processor in the electronics housing performs a method that includes activating the Peltier device to bring the seat to a preset temperature, receiving a temperature setting for the Peltier device from a temperature control button disposed on the handle, detecting a current temperature of an area within the seat, and if the current temperature of the area within the seat is greater than a threshold safe upper temperature, then deactivating the Peltier device.

A foldable push chair comprises a central body portion extending across the push chair and defining a central axis, the central axis extending substantially perpendicularly to the normal direction of travel of the push chair, a handle assembly connected to the central body and extending therefrom, at least three wheel supporting legs are rotatable around the central axis and extending from the central body, in the unfolded state one or more wheel supporting legs extend in a forward direction from the central axis and one or more wheel supporting legs extend in a rearward direction from the central axis; the forward and rearward extending legs are coupled together such that they rotate in opposite directions around the central axis during a folding or unfolding operation.

A handle folding mechanism, a three-fold handle employing the folding mechanism, and a stroller having the same are provided. The folding mechanism includes an intermediate component and a pair of connecting components. The intermediate component includes a tubular casing, a press block, and an unlocking piece. A rear part of the press block passes through a front surface of the casing to extend into the casing, and is movable back and forth. The connecting component includes a tubular housing and an engaging piece. The engaging piece is slidably mounted in the housing. In a locked state, a front end of the engaging piece penetrates into the casing. The unlocking piece has a fixing part, and the fixing part is disposed with a free end extending between a rear end of the press block and the front end of the engaging piece.
