Problems solved by technology

[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 longer, so in order to make the upper frame unfold stably, it is generally necessary to set a support rod on the frame to support the upper frame. This structural setting will affect the structural simplicity of the frame

Embodiment 1

[0056] Embodiment one: if figure 1 and figure 2 The shown stroller frame includes a bottom frame 1, an upper frame 2, a first locking mechanism 3 and a seat (not shown in the figure).

[0057]The front end of the bottom frame 1 is provided with a front wheel set 11 , and the rear end is provided with a rear wheel set 12 . The lower side of the upper frame 2 is pivotally connected to the front side of the bottom frame 1, and the upper side of the upper frame 2 is provided with at least one extension section 23 extending obliquely toward the rear side of the bottom frame 1 and an obliquely rearward In the extended push handle part 21 , the upper frame 2 has an expanded state forming an angle with the bottom frame 1 and a folded state close to the bottom frame 1 . The first locking mechanism 3 is disposed between the bottom frame 1 and the upper frame 2 for keeping the upper frame 2 in an unfolded state. The seat is arranged on the upper frame 2 . A stepping portion 22 is pr...

Embodiment 2

[0068] Embodiment two: if Figure 13 to Figure 18 As shown, the difference between this embodiment and the first embodiment is that the lower side of the upper frame 2 is pivotally connected to the rear side of the bottom frame 1, and the upper frame 2 has an expanded state with an included angle with the bottom frame 1 and has The folded state is close to the bottom frame 1 . Specifically, the rear side of the bottom frame 1 is also provided with an inclined section 15 extending obliquely towards the front side of the bottom frame 1 and matching with the inclination angle of the upper frame 2, so that when the upper frame 2 is in the unfolded state , the bottom frame 1 and the upper frame 2 have overlapped parts on the rear side, which increases the support arm between the two, and at the same time, through the locking effect of the first locking mechanism, the upper frame can be stably maintained in the unfolded state . In addition, when the upper frame 2 is in the unfolde...

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...
