DETAILED IMPLEMENTATION MANNER

[0031] The present utility model will be further described below in conjunction with the accompanying drawings:

[0032] Such as Figures 1 to 5As shown in the figure, a child stroller frame can move from an unfolded position to a folded position after the locking device is unlocked. It includes a front frame 1 and a rear frame 2 that is rotatably connected to the front frame 1 around a first axis A. A front wheel 1a is provided at the lower end of the front frame 1, and a rear wheel 2a is provided at the lower end of the rear frame 2. A support rod 3 is rotatably connected to the upper end of the front frame 1 or the rear frame 2 around a second axis B. In this embodiment, the front frame 1, the rear frame 2, and the support rod 3 are rotatably connected coaxially. A transmission mechanism 4 is provided between the support rod 3 and the front frame 1 and the rear frame 2, which can pull the front frame 1 to rotate and approach the rear frame 2 when the support rod 3 rotates and approaches the rear frame 2. An armrest assembly 5 is also connected to the support rod 3. The armrest assembly 5 includes a rotating sleeve 51 that is rotatably connected to the support rod 3 around an eighth axis H. An armrest rod 52 that can slide relative to it is provided inside the rotating sleeve 51. The rear end of the armrest rod 52 is rotatably connected to the transmission mechanism 4 around an eleventh axis K, so that when the transmission mechanism 4 pulls the front frame 1 to rotate and approach the rear frame 2, the armrest rod 52 slides inside the rotating sleeve 51 and approaches the rear frame 2. When folding is required, first unlock the locking device, and then rotate the support rod 3 backward to approach the rear frame 2. During this process, the transmission mechanism 4 pulls the front frame 1 to also rotate and approach the rear frame 2. Moreover, the rear end of the armrest rod 52 is pulled by the transmission mechanism 4, and the armrest rod 52 slides inside the rotating sleeve 51, and the rotating sleeve 51 rotates relative to the support rod 3, which also makes the armrest rod 52 approach the rear frame 2. Therefore, when the child stroller frame is folded, the armrest assembly 5 can follow the folding without the need to disassemble the armrest assembly 5, making the folding operation of the child stroller convenient and fast. Moreover, the entire child stroller frame has a simple structure, and the volume after folding is also small, which is convenient for carrying or storing. More importantly, when the child stroller is folded, the armrest rod 52 that extends obliquely forward and upward slides backward, so that the folded child stroller will not occupy a large space due to the armrest rod 52 extending too far forward. After the armrest rod 52 slides backward, the volume of the folded child stroller is smaller, which is more convenient for packaging and carrying and can be placed in the overhead bin of an airplane.

[0033] As Figures 1 to 5As shown, the child stroller frame also includes a push rod 6, so that the support rod 3 can be extended to facilitate pushing by adults.

One end of the second transmission rod 42 is rotatably connected to the front frame 1 around the sixth axis F, and the other end is rotatably connected to the lower end of the first transmission rod 41 around the seventh axis G. The rear end of the handrail is hinged on the first transmission rod 41 around the eleventh axis K. When folding, the push rod 6 is rotated forward and pressed downward, and the push rod 6 drives the support rod 3 and the first transmission rod 41 to rotate relative to the rear frame 2, so that the upper end of the support rod 3 and the upper end of the first transmission rod 41 are close to the lower end of the rear frame 2. When the first transmission rod 41 rotates relative to the rear frame 2, its lower end tilts upward and pulls the second transmission rod 42, and the second transmission rod 42 pulls the front frame 1 to rotate relative to the rear frame 2 so that the front frame 1 is close to the rear frame 2. In this process, the first transmission rod 41 drives the rear end of the handrail rod 52 to move and rotate relatively, and the handrail rod 52 slides backward in the rotating sleeve 51, and the rotating sleeve 51 rotates relative to the support rod 3, so that the handrail rod 52 is also close to the rear frame 2. The entire child stroller has a simple frame structure, few rods, and the folding operation is very convenient and quick, and only needs to be turned forward and pressed. The push rod 6 is small in size after folding, which is easy to carry.
