Baby carriage frame

Abstract

The invention provides a baby carriage frame. The baby carriage frame comprises a bottom frame, an upper frame, a first locking mechanism and a seat. A front wheel set is arranged at the front end of the bottom frame, and a back wheel seat is arranged at the back end; the lower side of the upper frame is pivoted with one side of the bottom frame, the upper side of the upper frame is provided with an extension section which obliquely extends towards the other side of the bottom frame and a push handle part which obliquely extends backwards, and the upper frame has an unfolded state in which an included angle is formed between the upper frame and the bottom frame and a folded state in which the upper frame is close to the bottom frame; the first locking mechanism is arranged between the bottom frame and the upper frame and used for keeping the upper frame in an unfolded state, and the seat is arranged on the upper frame; a treading part is arranged at the lower end of the upper frame, and the upper frame can pivot relative to the bottom frame by treading the treading part so that the upper frame can rotate from the folded state to the unfolded state. In the baby carriage frame, the upper frame can be unfolded by treading the treading part at the lower end of the upper frame with feet and taking the pivoting point between the upper frame and the bottom frame as a fulcrum and by utilizing the lever principle, so that a user can unfold the bicycle without bending down, and the use is convenient.

Description

【Technical field】 [0001] The present application relates to the field of baby products, in particular to a stroller frame. 【Background technique】 [0002] At present, in the L-shaped stroller frame, it generally includes an upper frame and a lower frame arranged in an L shape. Most of the pivot joints between the upper frame and the lower frame are close to the bottom of the upper frame, resulting in the rotation above the pivot point. The moment arm of the upper frame is relatively long, so in order to enable the upper frame to unfold stably, it is generally necessary to set support rods on the frame to support the upper frame. This structural setting will affect the structural simplicity of the frame. 【Content of invention】 [0003] In order to further simplify the structure of the product, the present application provides a stroller frame. [0004] The application is realized by the following technical solutions: [0005] Stroller frame, including: [0006] The botto...
