As shown in fig. 1-4, the utility model discloses a child's bike includes chassis 1, upper enclosing frame 2 and push rod 3, and upper enclosing frame 2 is located the top of chassis 1, and push rod 3 sets up on chassis 1, and it is used for pushing away or pulling away this child's bike. The child's vehicle further comprises a front wheel assembly 6 provided at the bottom front portion of the chassis 1 and a rear wheel assembly 7 provided at the bottom rear portion of the chassis 1.

The buggy has an unfolded state and a folded state. When the stroller is in the unfolded state, the upper surrounding frame 2 is in the unfolded position, which is away from the bottom frame 1, and an accommodating space is formed between the bottom frame 1 and the upper surrounding frame 2, and the accommodating space is used for seating and lying of a child or for placing articles, as shown in fig. 1 and 2. When the stroller is in the folded position, the upper enclosure 2 is in the folded position, which is shown in fig. 3 and 4, and it is brought close to the chassis 1. Preferably, the upper enclosure frame 2 is parallel to the base frame 1 in both the deployed and folded positions.

The child's vehicle also comprises a folding mechanism which is connected between the bottom frame 1 and the upper surrounding frame 2. The folding mechanism can be unfolded and folded, the unfolding action of the folding mechanism can drive the upper surrounding frame 2 to be in the unfolding position, and the folding action of the folding mechanism can drive the upper surrounding frame 2 to be in the folding position.

Specifically, the folding mechanism includes a first diagonal support 41, a second diagonal support 42, a first link 43, and a second link 44.

The first diagonal brace 41 and the second diagonal brace 42 are both obliquely arranged along the vertical direction, and the first diagonal brace 41 and the second diagonal brace 42 are crossed and rotatably connected at the crossed position through a first shaft 51. One end of the first link 43 is rotatably connected to the upper frame 2 via a second shaft 52, and one end of the second link 44 is rotatably connected to the base frame 1 via a third shaft 53. One of the upper end portion of the first diagonal brace 41 and the upper end portion of the second diagonal brace 42 is rotatably connected to the other end portion of the first link 43 via a fourth shaft 54, and the other of the upper end portion of the first diagonal brace 41 and the upper end portion of the second diagonal brace 42 is rotatably connected to the upper enclosure frame 2 via a fifth shaft 55. One of the lower end of the first diagonal strut 41 and the lower end of the second diagonal strut 42 is rotatably connected to the other end of the second link 44 by a sixth shaft 56, and the other of the lower end of the first diagonal strut 41 and the lower end of the second diagonal strut 42 is rotatably connected to the undercarriage 1 by a seventh shaft 57.

Thus, a four-bar linkage is formed among the upper surround frame 2, the first link 43, the first diagonal brace 41, and the second diagonal brace 42, and a four-bar linkage is also formed among the base frame 1, the second link 44, the first diagonal brace 41, and the second diagonal brace 42. The axial center of the first shaft 51, the axial center of the fourth shaft 54, the axial center of the second shaft 52 and the axial center of the fifth shaft 55 are sequentially connected to form a first quadrilateral structure, and the axial center of the first shaft 51, the axial center of the sixth shaft 56, the axial center of the third shaft 53 and the axial center of the seventh shaft 57 are sequentially connected to form a second quadrilateral structure.

Preferably, the first quadrilateral structure and the second quadrilateral structure are arranged in an axisymmetric manner, or the first quadrilateral structure and the second quadrilateral structure are arranged in a centrosymmetric manner. Therefore, the child bicycle has attractive appearance and simple processing technology.

The second, fourth and

fifth shafts

52, 54, 55 are all located above the first shaft 51, and the third, sixth and

seventh shafts

53, 56, 57 are all located below the first shaft 51.

The first link 43 and the second link 44 may be located on the same one of the left and right sides of the first shaft 51, and the first link 43 and the second link 44 may be located on different ones of the left and right sides of the first shaft 51.

The first link 43 and the second link 44 each extend in the vertical direction when the upper peripheral frame 2 is in the deployed position, and preferably the first link 43 and the second link 44 extend in the same direction when the first link 43 and the second link 44 are located on the same one of the left and right sides of the first shaft 51, and the first link 43 and the second link 44 are parallel when the first link 43 and the second link 44 are located on different ones of the left and right sides of the first shaft 51.

In this embodiment, the other end of the first link 43 is rotatably connected to the upper end of the first diagonal member 41 via a fourth shaft 54, and the upper end of the second diagonal member 42 is rotatably connected to the upper enclosure frame 2 via a fifth shaft 55. The other end of the second link 44 is rotatably connected to the lower end of the second diagonal strut 42 via a sixth shaft 56, and the lower end of the first diagonal strut 41 is rotatably connected to the undercarriage 1 via a seventh shaft 57. That is, the first link 43 and the second link 44 are located on the same one of the left and right sides of the first shaft 51. As shown in fig. 1 to 4.

The buggy further comprises a locking mechanism for locking the upper enclosure 2 in the unfolded position, which locking mechanism can be arranged between any two rotatably connected parts of the two four-bar linkages, both four-bar linkages being in a locked state as long as the positions of these two parts are locked, the upper enclosure 2 being locked in the unfolded position.

In this embodiment, the folding mechanism is respectively disposed between the front end portion of the bottom frame 1 and the front end portion of the upper surrounding frame 2, and between the rear end portion of the bottom frame 1 and the rear end portion of the upper surrounding frame 2.

When the upper enclosure frame 2 is switched from the unfolded position to the folded position, after the locking mechanism is unlocked, the upper enclosure frame 2 is pressed downwards, so that the first diagonal brace 41 and the second diagonal brace 42 rotate and are folded relatively, and the upper enclosure frame 2 moves downwards to be close to the underframe 1 in a state of keeping parallel to the underframe 1 until the upper enclosure frame and the underframe 1 are close together.

When the upper enclosing frame 2 is in the folding position, the push rod 3 and the underframe 1 are close to each other, and the child car is in the folding state.

When the baby carriage is unfolded from the folded state, the push rod 3 is reversely moved to the unfolded position, and then the upper surrounding frame 2 is lifted upwards, the first diagonal brace 41 and the second diagonal brace 42 are relatively rotated and unfolded, so that the upper surrounding frame 2 can be moved upwards away from the underframe 1 in a state of keeping parallel with the underframe 1 until the upper surrounding frame is moved to the unfolded position.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
