Description
Technical field
The utility model relates to a kind of perambulator, particularly relates to a kind of folding backrest structure of perambulator.
Background technology
Perambulator has been that a kind of infant goes on a journey indispensable instrument, and user, outside firm, the safe basic demand pursuing perambulator, more and more payes attention to the features such as the volume of perambulator is little, light, collapsible.Possess the perambulator of above feature, can prevent from easily tying up in automobile trunk, on the bus or train of trip, also can reduce its volume taken, thus greatly facilitate trip and carry.
The folding backrest structure of perambulator generally comprises the back support bar in both sides and is arranged on the folding support rod assembly between two back support bar, existing folding support rod assembly is generally the less foldable structure of rod member, when this kind of folding support rod assembly is in softened state, spacing between rod member is larger, stressed effect is poor, and rigidity is not enough.In addition, existing folding support rod assembly generally uses main support structure at middle part, and when this also makes the child back taken and its laminating, traveling comfort is lower, permeability to air is poor.
Summary of the invention
The utility model object is: the folding backrest structure providing a kind of perambulator, it has the X-type folding strut that multiple pin joint connects, and between rod member, spacing is less, and stressed effect is better, rigidity is stronger, middle hollow space is more and be evenly distributed, and improves permeability to air and comfort level.
The technical solution of the utility model is: a kind of folding backrest structure of perambulator, comprise left back support bar, right back support bar, and pin joint is on a left side, folding support rod assembly between right back support bar, described folding support rod assembly at least comprises multiple transversely arranged X-type folding strut, the upper right side and the bottom righthand side that are positioned at the X-type folding strut in left side in two adjacent X-type folding struts are connected with the left upper end of X-type folding strut and the corresponding pin joint of lower-left end that are positioned at right side respectively, be positioned in multiple X-type folding strut the left upper end of the X-type folding strut of the leftmost side and lower-left end respectively directly or indirectly with left back support bar pin joint, be positioned in multiple X-type folding strut the upper right side of the X-type folding strut of the rightmost side and bottom righthand side respectively directly or indirectly with right back support bar pin joint.
Further, described folding support rod assembly also includes left connecting rod and right connecting rod, the left upper end of the X-type folding strut of the leftmost side and/or the right-hand member pin joint of lower-left end and left connecting rod is positioned in multiple X-type folding strut, the left end of left connecting rod and left back support bar pin joint, the upper right side of the X-type folding strut of the rightmost side and/or the left end pin joint of bottom righthand side and right connecting rod is positioned at, the right-hand member of right connecting rod and right back support bar pin joint in multiple X-type folding strut.Above-mentioned X-type folding strut is made up of pin joint in the middle part of two struts.
The utility model has the advantages that: the utility model has the X-type folding strut that multiple pin joint connects, compared with traditional folding support rod assembly, between rod member, spacing is less, and stressed effect is better, rigidity is stronger, middle hollow space is more and be evenly distributed, and improves permeability to air and comfort level.

Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the decomposition texture schematic diagram of Fig. 1;
Fig. 3 is the structural representation of Fig. 1 when specifically implementing.
Wherein: 1 left back support bar; 2 right back support bar; 3 folding support rod assemblies; 31X type folding support rod; 32 left connecting rods; 33 right connecting rods.
Detailed description of the invention
Embodiment: as shown in Figure 1 to Figure 3, a kind of folding backrest structure of perambulator, comprise left back support bar 1, right back support bar 2, and pin joint is on a left side, right back support bar 1, folding support rod assembly 3 between 2, described folding support rod assembly 3 comprises four transversely arranged X-type folding struts 31, left connecting rod 32 and right connecting rod 33, the upper right side and the bottom righthand side that are positioned at the X-type folding strut 31 in left side in two adjacent X-type folding struts 31 are connected with the left upper end of X-type folding strut 31 and the corresponding pin joint of lower-left end that are positioned at right side respectively, the left upper end of the X-type folding strut 31 of the leftmost side and the right-hand member pin joint of left connecting rod 32 is positioned in multiple X-type folding strut 31, the left end of left connecting rod 32 and left back support bar 1 pin joint, the lower-left end being positioned at the X-type folding strut 31 of the leftmost side in multiple X-type folding strut 31 directly with left back support bar 1 pin joint, the upper right side of the X-type folding strut 31 of the rightmost side and the left end pin joint of right connecting rod 33 is positioned in multiple X-type folding strut 31, the right-hand member of right connecting rod 33 and right back support bar 2 pin joint, the bottom righthand side being positioned at the X-type folding strut 31 of the rightmost side in multiple X-type folding strut 31 directly with right back support bar 2 pin joint.Above-mentioned X-type folding strut 31 is made up of pin joint in the middle part of two struts.
