Description

Technical Field

[0001] The utility model belongs to the field of children's products, and particularly relates to a foldable intelligent baby carriage. Background Art

[0002] Baby carriages are used to carry children at home or when going out, which is convenient for family members to carry and take care of children at any time. The existing baby carriages are of pure mechanical structure, unable to ventilate the children in the baby carriage, nor can they remotely monitor the baby in the carriage. When carrying children, users need to manually push the carriage frame forward. If the road resistance is large, users can only increase the pushing force. When users pick up children and walk, the baby carriage also needs to be pushed or pulled by users and cannot be let go, which is a bit cumbersome. Moreover, with the increase in the height of the younger generation of parents and children, the height of the furniture and supplies they use also needs to increase to reduce the bending amplitude of the users. Especially when putting children into or picking them up from the baby carriage, a higher baby carriage can effectively reduce the burden of parents bending down. Currently, most of the front legs, rear legs, and push rods of baby carriages use the same hinge point. If the height of the vehicle body is increased, while ensuring the front and rear length of the vehicle body, the front legs and rear legs need to be lengthened, so the height after the vehicle body is folded is also relatively large, which is not convenient for packaging, transportation, and storage.

Insertion posts are provided on the two outer rotating pieces 401, and the upper ends of the two rear legs 1 are sleeved on the insertion posts to form a connection. The upper ends of the two inner rotating pieces 402 are respectively connected to the two push rods 7. By swinging the two push rods 7, the two inner rotating pieces 402 are driven to swing. Cantilevers 403 are respectively fixed at the lower ends of the two inner rotating pieces 402, and the ends of the two cantilevers 403 are respectively hinged to the upper ends of the two front legs 5. Short rods 17 are also hinged to the upper parts of the two front legs 5, and the other ends of the two short rods 17 are respectively hinged to the upper parts of the two rear legs 1 to form a four-bar linkage mechanism.

[0084] The two first connecting parts 15 adopt a plug structure with the port facing upward. The two first connecting parts 15 are respectively of an integral structure with an inner rotating piece 402, which can ensure the stability of the baby carrier 13 when plugged on the vehicle frame.

[0085] When unfolding the vehicle frame, pull out the U-shaped handle 8 from the push rod 7. By swinging the push rod 7 upward, the inner rotating piece 402 is driven to swing upward relative to the outer rotating piece 401. At this time, the two cantilevers 403 swing downward until they are aligned with the two rear legs 1, pulling the two front legs 5 to open forward. At this time, the rotation positioning mechanism is locked, and the cantilever 403 is relatively fixed to the rear leg 1, so that the front leg 5, the short rod 17 and the rear leg 1 form a triangular stable mechanism.

[0086] When folding up the vehicle frame, push the U-shaped handle 8 into the push rod 7 to unlock the rotation positioning mechanism, and then press down the push rod 7 to drive the inner rotating piece 402 to swing downward relative to the outer rotating piece 401.
