Novel baby carriage frame

Abstract

The invention discloses a novel baby carriage frame, which comprises front foot rods, rear foot rods and push rods, wherein a seat part is relatively fixed between the upper portions of the two frontfoot rods, and a joint assembly can be arranged on the seat part or the front foot rod. According to the invention, through a unlocking assembly, the joint assembly can be controlled to be unlocked, so that the push rods can be folded backwards relative to the front foot rods and the seat, the seat part is disassembly-free when folding, and finally after the whole baby carriage is folded, the seatpart is low in front portion and high in back portion and inclines so as to achieve folding minimization; the upper ends of the rear foot rods are hinged to the bottoms of the seat part, and the seatpart has an integrally-formed structure, so that the corresponding rod member is reduced compared with the existing folding baby carriage frame so as to conveniently assemble and manufacture and increase the space in reducing of production cost and improving of product competitiveness; and when the baby carriage frame is unfolded for use, the upper ends of the rear foot rods can provide powerfulsupport for the seat part, so that use safety and reliability are further ensured.

Description

【Technical field】 [0001] The invention relates to a stroller, in particular to a novel stroller frame. 【Background technique】 [0002] In order to facilitate the carrying and storage of baby carriages, there are many types of baby carriages in the prior art, mainly including foldable baby carriages. Among the existing foldable baby carriages, due to their complex design and structure, folding is inconvenient, especially for hard seats. The seat portion cannot be folded during folding, therefore, the whole vehicle still has a relatively large volume after being folded, which is inconvenient to carry and store. As for the flexible or foldable seat, its structure is relatively complicated, resulting in high manufacturing cost, which is not conducive to improving the competitiveness of the product in the market. [0003] In addition, most of the existing folding baby carriages are folded through a four-bar mechanism, such as Figure 8 As shown, the lower end of the push rod a1 ...

Problems solved by technology

However, if this design structure or a similar design structure is adopted, additional rods are added to form a seat frame, and then the corresponding seat cloth software is put on the seat frame, which is not convenient for controlling the manufacturing cost

[0004] Furthermore, some of the existing folding baby carriages are gear synchronous linkage to realize folding or unfolding, such as Figure 9 As shown, the push rod b1 and the end of the front leg b3 are meshed through the tooth block assembly b2 and are rotatably connected to the upper end of the rear leg b4. Closer or farther away, with this design structure, it is also necessary to add additional rods to form a seat frame, and then put the corresponding seat cloth software on the seat frame, and the manufacturing cost of the tooth block assembly is not only high, but also prone to shrinkage out of sync defect
