Description

Technical Field

[0001] The utility model relates to the technical field of children's products, in particular to a linkage-foldable baby carriage. Background Art

[0002] Children's bicycles are a major category of travel products, including children's bicycles, strollers, baby walkers, tricycles, and electric vehicles. Children's bicycles are suitable for children aged 4 to 8 years old. When purchasing, consider the child's age and height to choose the appropriate size, that is, a bicycle with a saddle height between 435 and 635 mm. When choosing a bicycle, pay attention to the size of the handbrake handle.

[0003] For example, a folding platform structure for a baby stroller with authorization announcement number "CN207360394U" can easily fold and unfold the seat frame tube and front leg tubes through the coordinated actions of the seat frame tube's movable connecting piece, branch tubes, and joint mechanisms. During the folding and unfolding process, the front leg tubes are automatically folded and unfolded by the seat frame tube and the linkage of the movable connecting piece, eliminating the need for manual operation. This is convenient to operate, saves time and effort, and is very convenient for use by the elderly and women. However, this folding platform structure for a baby stroller requires the operator to use a large amount of force to move the seat frame downward, making it inconvenient for the operator to fold it in a coordinated manner, thereby reducing the practicality of the baby stroller. At the same time, when the baby stroller is carrying heavy items, the front and rear leg tubes may bend, causing damage to the baby stroller and increasing the maintenance cost of the baby stroller. Utility Model Content

[0024] Working principle:

[0025] When you need to fold the stroller in a linked manner:

[0026] Front and rear leg folding stage:

[0027] When the baby carriage needs to be folded in a linked manner through the front leg tube 3 and the rear leg tube 7, the operator rotates the knob 201, the knob 201 drives the worm 202 to rotate, the worm 202 drives the worm gear 203 to rotate, the worm gear 203 drives the first bevel gear 204 to rotate, the first bevel gear 204 drives the two second bevel gears 205 on both sides to rotate, the two second bevel gears 205 respectively drive the two rotating rods 206 to rotate, and the two rotating rods 206 respectively drive the front leg tube 3 and the rear leg tube 7 to rotate. After the front leg tube 3 and the rear leg tube 7 rotate to a suitable angle, the operator stops rotating the knob 201, so that the front leg tube 3 and the rear leg tube 7 rotate synchronously, thereby realizing the linked folding of the baby carriage.

[0028] Front and rear leg support stage:

[0029] When the operator turns the knob 201, the external power supply of the motor 601 is connected, the motor 601 is started, the motor 601 drives the gear 602 to rotate, the gear 602 drives the rack 603 to move, the rack 603 moves on the slide bar 606 and drives the connecting rod 604 to move, the connecting rod 604 drives the sleeve 605 to move, and the sleeve 605 supports the front leg tube 3 and the rear leg tube 7 to prevent the front leg tube 3 and the rear leg tube 7 from bending due to the large pressure. The folding of the baby stroller is completed in this way.

[0030] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
