Furthermore, a locking assembly is arranged at the joint of the front foot assembly 1 and the handle assembly 4, and a handle button 13 for controlling the action of the locking assembly is arranged on the handle assembly 4, so that the front foot assembly 1 and the handle assembly 4 are relatively fixed or can relatively rotate, the use safety of the baby carriage can be improved, and accidents caused by the fact that the baby carriage is easily folded can be avoided.

The folding and unfolding principle and process of the baby carriage provided by the embodiment are explained as follows:

when the stroller is in the unfolded state and needs to be switched to the folded state, a user can use a foot to step on the pedal 5, the first transmission gear 71 of the pedal 5 rotates around the first rear foot connecting rod 203, the connecting seat 501 is directly embedded into the clamping groove 801, force is applied to the clamping plug 802 through the guide inclined surface 503 of the connecting seat 501, the clamping plug 802 is retracted until the clamping plug 802 crosses the guide inclined surface 503, and the clamping plug 802 extends out of the clamping hole 502 under the action of a compression spring and is inserted into the clamping hole 502, so that the pedal 5 is locked. Meanwhile, in the process of downward rotation of the pedal 5, the first transmission gear 71 rotates to drive the second transmission gear 72 to rotate, the second transmission gear 72 rotates to drive the transmission lever 73 to rotate, and the folding spring is pulled open in the process of rotation of the transmission lever 73 until the folding spring is in an open state. At this time, the user opens the locking assembly by the handle button 13, so that the front foot assembly 1 and the handle assembly 4 can relatively rotate, because the folding spring is in an open state, the front foot assembly 1 and the rear foot assembly 2 are pulled to approach each other and rotate, thereby driving the seat frame component 3 to rotate by taking the joint of the seat frame component and the rear foot component 2 as a fulcrum and switching to a folding state, meanwhile, the handle component 4 can rotate by taking the joint of the handle component and the front foot component 1 as a fulcrum and switch to a folding state, namely the whole bicycle can be switched from an opening state to a folding state, wherein the handle component 4 is finally clamped by the folding hook 11 in the folding process, so that the baby carriage can be in a stable folding state and cannot be easily opened, meanwhile, in the process that the whole vehicle is switched from the opening state to the folding state, the elastic component 6 can be gradually stretched to the opening state so as to provide power for switching the whole vehicle from the folding state to the opening state.

When the stroller is in the folded state and needs to be switched to the unfolded state, a user can use the kick button 12, the kick button 12 firstly triggers the car collection hook 11, so that the car collection hook 11 rotates and is separated from the handle assembly 4, the kick button 12 then pulls the clamping plug 802 through the connecting member to separate the clamping plug 802 from the clamping hole 502, and the kick pedal 5 returns under the action of the return torsion spring and prepares for the next folding of the stroller. Because the elastic assembly 6 is in the open state, the elastic assembly 6 is contracted at the moment, the front foot assembly 1 and the seat frame assembly 3 are pulled to approach each other and rotate, meanwhile, the rear foot assembly 2 rotates and switches to the open state by taking the joint of the rear foot assembly 2 and the front foot assembly 1 and/or the joint of the rear foot assembly 2 and the seat frame assembly 3 as a fulcrum, and simultaneously, the handlebar assembly 4 rotates and switches to the open state by taking the joint of the front foot assembly 1 as a fulcrum, thereby completing the process of switching the whole baby carriage from the folded state to the open state.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, such as other mechanical or electronic solutions to achieve the same purpose and technical effect, which all belong to the protection scope of the present invention.
