The technical solution of the utility model is: a kind of self-support supporting mechanism of doll carriage, comprise push rod, the front-wheel support that upper end and push rod bottom are rotationally connected, the rear wheel support that upper end and push rod bottom are rotationally connected, and opening U-shaped seat pillar forward, the front end of described seat pillar is connected with the front-wheel support pin joint, the rear portion of seat pillar is connected with the rear wheel support pin joint, be rotatably connected to lower attaching parts on the brake outer tube of described rear wheel support bottom, the front portion riveted joint of lower attaching parts has the feet that extends forward, be rotatably connected to upper connector on the rear transverse rod of described seat pillar, riveted joint has the spike pipe link between the front portion of upper connector and lower attaching parts, when the go-cart vehicle frame folding, front-wheel support and rear wheel support draw in, the rear transverse rod of seat pillar rotates to the front lower place, the front end that the spike pipe link drives feet rotates to the back lower place, feet is cooperated with the trailing wheel of rear wheel support lower end and realizes that the car load automatic standing establishes.
Further, described feet is T-shaped, its by about two L-type strut bars oppositely form the rear end of these two L-type strut bars and the coaxial riveted joint of lower attaching parts by establishing.
The utility model has the advantages that:
1. the utility model is when vehicle frame folding, the front end that is driven feet by seat pillar and spike connecting strap rotates to the back lower place, feet is cooperated with the trailing wheel of rear wheel support and realize that the car load automatic standing establishes, so that all can standing anywhere, establishes the doll carriage after folding, not only floor area is less but also have preferably stability, and vehicle frame falls down and hurts sb.'s feelings when having avoided mistake to bump.
. feet of the present utility model is T-shaped, has increased like this area of contact on feet and ground, has improved the stability when folding rear carriage is vertical to be established.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the schematic diagram of the utility model complete vehicle structure;
Schematic diagram when Fig. 2 is the utility model complete vehicle structure semi-collapsed condition; (not drawing trailing wheel)
Schematic diagram when Fig. 3 is the folding standing state of the utility model complete vehicle structure.
Wherein: 1 push rod; 2 front-wheel supports; 3 rear wheel supports; 4 seat pillars; 41 rear transverse rods; 5 brake outer tubes; 6 times attaching partss; 7 feets; 71 L-type strut bars; 8 upper connectors; 9 spike pipe links; 10 trailing wheels; 11 2 roads lock button; 12 handle knob; 13 first rivets; 14 second rivets; 15 the 3rd rivets; 16 the 4th rivets.
The specific embodiment
Embodiment: as shown in Figure 1 to Figure 3, a kind of self-support supporting mechanism of doll carriage, comprise push rod 1, the front-wheel support 2 that upper end and push rod 1 bottom are rotationally connected, the rear wheel support 3 that upper end and push rod 1 bottom are rotationally connected, and opening U-shaped seat pillar 4 forward, the front end of described seat pillar 4 is connected with front-wheel support 2 pin joints, the rear portion of seat pillar 4 is connected with rear wheel support 3 pin joints, be rotatably connected to lower attaching parts 6 on the brake outer tube 5 of described rear wheel support 3 bottoms, the front portion riveted joint of lower attaching parts 6 has the feet 7 that extends forward, be rotatably connected to upper connector 8 on the rear transverse rod 41 of described seat pillar 4, riveted joint has spike pipe link 9 between the front portion of upper connector 8 and lower attaching parts 6, when the go-cart vehicle frame folding, front-wheel support 5 draws in rear wheel support 6, the rear transverse rod 41 of seat pillar 4 rotates to the front lower place, the front end that spike pipe link 9 drives feets 7 rotates to the back lower place, feet 7 is cooperated with the trailing wheel 10 of rear wheel support 3 lower ends and realizes that the car load automatic standing establishes.Doll carriage after folding like this all can stand anywhere to be established, and not only floor area is less but also have preferably stability, and vehicle frame falls down and hurts sb.'s feelings when having avoided mistake to bump.
Described feet 7 is T-shaped, its by about two L-type strut bars 71 oppositely form by establishing, these two L-types support 71 rear end and lower attaching parts 6 coaxial riveted joints.Increase like this area of contact of feet 7 with ground, improved the stability when folding rear carriage is vertical to be established.
When the utility model was implemented, the concrete motion process of each parts was as follows:
During vehicle frame folding, stressed in handling knob 12, so that the vehicle frame release when pinning on the push rod 1 two roads lock button 11; At this moment, push rod 1 is applied one to the power F1 that presses down, so that 16 4 points of the 4th rivet that vehicle frame is pressed between the 3rd rivet 15, push rod and the rear wheel support between the second rivet 14, push rod and the front-wheel support between the first rivet 13, seat pillar and the front-wheel support between seat pillar and the rear wheel support shrink; As shown in Figure 3, seat pillar 4 rotatablely moves around the first rivet 13, the second rivet 14 in the folding process of returning the vehicle to the garage and knock off, and is connected to the effect that spike pipe link 6 on the seat pillar 4 is subject to the power F2 that seat pillar 4 moves downward this moment; Feet 5 rotates to the back lower place take brake outer tube 5 as centre of gration under the effect of power F2, when rotating to the certain displacement amount, so that vehicle frame can obtain the function of supporting oneself by the additional forces of feet 5.
When vehicle frame launches, apply a power F3 who upwards carries at push rod 1; At this moment, vehicle frame launches by the first rivet 13, the second rivet 14, the 3rd rivet 15,16 4 points of the 4th rivet; Be connected to the effect that spike pipe link 6 on the seat pillar 4 is subject to the power F4 of seat pillar 4 upward movements; Feet 5 shrinks to the front upper place take brake outer tube 5 as centre of gration under the effect of tensile force f 4, and when vehicle frame launched fully, feet 5 was retracted to position shown in Figure 1.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
