[ Detailed description ] of the invention
The invention is further described below with reference to the accompanying drawings:
Example 1:
As shown in fig. 1 to 4, a stroller movable from an unfolded position to a folded position after a locking device is unlocked, comprising:
the front leg (1), the lower end of the front leg (1) is rotatably connected with a front wheel connecting frame (2), and the front wheel connecting frame (2) is connected with a front wheel (3);
The rear leg 4, the lower end of the rear leg 4 is connected with a rear wheel 5, a rear stay bar 6 which is rotationally connected with the upper end of the rear leg 4 and the front leg 1 is arranged between the upper end of the rear leg and the front leg;
One end of the first connecting rod 7 is rotationally connected with the rear leg 4, and the other end of the first connecting rod 7 is rotationally connected with the front leg 1;
And one end of the second connecting rod 8 is rotationally connected with the front wheel connecting frame 2, and the other end of the second connecting rod 8 is rotationally connected with the rear stay bar 6.
As shown in fig. 2 to 4, when the stroller is folded, the lower end of the rear stay bar 6 is pulled obliquely backward to lift the stroller, the rear stay bar 6 rotates relative to the front leg 1, and when the lower end of the rear stay bar 6 moves obliquely backward, the front wheel connecting frame 2 is pulled by the second connecting rod 8 to rotate relative to the front leg 1, so that the front wheel connecting frame 2 and the front wheel 3 are folded. Meanwhile, when the lower end of the rear stay bar 6 is pulled, the upper end of the rear leg 4 is also pulled, the upper end of the rear leg 4 has a trend of outward movement, a first connecting rod 7 hinged with the rear leg 4 and the front leg 1 is arranged between the rear leg 4 and the front leg 1, and the first connecting rod 7 pulls the rear leg 4 when the baby carriage is lifted by combining the self weights of the rear leg 4 and the rear wheel 5, so that the lower end of the rear leg 4 is folded towards the front leg 1. Therefore, the folding of the baby carriage can be conveniently realized by only applying the pulling force obliquely upwards to the rear stay bar 6, and the whole process is very convenient and quick to operate. The whole baby carriage has simple structure, small volume after folding and convenient carrying.
In this embodiment, the seat of the stroller may be suspended from the frame using a flexible seat pocket, and the infant sits in the seat pocket. When the baby carriage walks, a user can push the upper ends of the front legs 1 to push the baby carriage to walk. Of course, if the convenience of pushing the stroller is pursued, the push rod 9 may be slidably connected to the front leg 1, and the push rod 9 may be one or more telescopic rods. When the baby carriage is folded, the hand push rod 9 can be retracted into the front leg 1, or the rear leg 4 and the front wheel connecting frame 2 can be folded by pulling the rear stay bar 6, and then the hand push rod 9 is retracted. The locking means of the pushchair may be of conventional construction, for example by providing a pivotable hook on the rear leg 4 and a pin on the rear stay 6 which cooperates with the hook when the pushchair is deployed.
As shown in fig. 1 to 3, the second link 8, the rear stay 6 and the rear leg 4 are coaxially hinged, and the first link 7, the front leg 1 and the front wheel link 2 are coaxially hinged. Therefore, the baby carriage is flexible to fold and convenient to operate when being folded.
As shown in fig. 1, the front wheel connecting frame 2 is provided with a transverse rod 10, the second connecting rod 8 is hinged on the transverse rod 10 to realize rotary connection with the front wheel connecting frame 2, the transverse rod 10 is arched, and the second connecting rod 8 is hinged at the arched bottom of the arched transverse rod 10. Therefore, the connecting position of the second connecting rod 8 and the transverse rod 10 is positioned at a far position below the connecting position of the first connecting rod 7 and the front leg 1, so that the second connecting rod 8 can pull the front wheel connecting frame 2 to rotate more easily when the baby carriage is folded, the folding is more flexible, and the folding operation is more convenient.
Example 2:
example 2 differs from example 1 in that:
As shown in fig. 5, a push rod 9 is rotatably connected to the upper end of the front leg 1. When the baby carriage is folded, the hand push rod 9 can be rotated relative to the front leg 1 to fold, or the rear leg 4 and the front wheel connecting frame 2 can be folded by pulling the rear stay rod 6, and then the hand push rod 9 can be rotated.
Example 3:
Example 3 differs from example 1 in that:
As shown in fig. 6 and 7, the rear stay bar 6 is provided with an upwardly protruding connection lug 11, the connection lug 11 is connected with a seat bar 12, the seat bar 12 is further provided with a connection part 13, and the seat bar 12 is rotatably connected with the front leg 1 through the connection part 13. Therefore, the seat of the baby carriage is supported by the seat rod 12, a structure of hanging a flexible seat pocket is not adopted, and when the baby is folded, the rear supporting rod 6 rotates relative to the front leg 1, the rear supporting rod 6 pushes the seat rod 12 through the connecting lug 11 on the rear supporting rod, the seat rod 12 rotates relative to the front leg 1 through the connecting part 13, the folding of the seat rod 12 is realized, and the seat rod 12 is folded together when the baby carriage is folded, so that the operation is very convenient.
As shown in fig. 6 to 10, the stroller further comprises a backrest 14, the seat rod 12 is provided with a fixed connection position 15 and a sliding seat 16 capable of sliding relative to the seat rod 12, the lower end of the backrest 14 is rotatably connected with the sliding seat 16, and a linkage rod 17 hinged with the connection position 15 and the backrest 14 is arranged between the connection position and the backrest 14. When the baby carriage is folded, the backrest 14 is pushed forward, and the lower end of the backrest 14 is rotationally connected with the sliding seat 16, and the backrest 14 is hinged with the linkage rod 17, so that when the backrest 14 is pushed forward, the backrest 14 rotates around the joint position of the backrest 14 and the linkage rod 17, and the lower end of the backrest 14 moves towards the rear end of the seat rod 12 through the sliding of the sliding seat 16 on the seat rod 12, and meanwhile, the linkage rod 17 also rotates around the joint position of the backrest 17 and the connecting position 15, thereby realizing the folding of the backrest 14. When the backrest 14 is folded, the lower end of the rear stay bar 6 can be pulled and lifted, the rear leg 4 is closed towards the front leg 1, the front wheel connecting frame 2 is rotated and folded relative to the front leg 1, and finally the hand push rod 9 is retracted. The connecting position 15 may be a protruding block provided on the seat post 12, which may be integrally formed with the seat post 12, or may be a separate component fixed to the seat post 12 by a screw or a rivet.
