Furthermore, it is possible to provide a device for the treatment of a disease. The first link 310 is rotatably connected to the second link 320, and a rotational connection portion of the first link 310 and the second link 320 is located between the first side bracket 100 and the second side bracket 200 in the left-right direction. In this embodiment, the first end 311 is rotatably connected to the first side bracket 100 about a first axis 1001, the second end 312 is rotatably connected to the second side bracket 200 about a second axis 1002, the third end 321 is rotatably connected to the first side bracket 100 about a third axis 1003, the fourth end 322 is rotatably connected to the second side bracket 200 about a fourth axis 1004, the first link 310 is rotatably connected to the second link 320 about a fifth axis 1005, and the first axis 1001, the second axis 1002, the third axis 1003, the fourth axis 1004, and the fifth axis 1005 are parallel to each other.
In this embodiment, the first end 311 is spaced apart from the third end 321 on one side of the first side bracket 100, and the second end 312 is spaced apart from the fourth end 322 on one side of the second side bracket 200. When the stroller is in the deployed state, the first end 311 is positioned above the third end 321, the fourth end 322 is positioned above the second end 312, and/or the first end 311 is positioned rearward of the third end 321, and the fourth end 322 is positioned rearward of the second end 312. In this embodiment, specifically, the first end 311 is located above and behind the third end 321, and the fourth end 322 is located above and behind the second end 312. In this embodiment, when the stroller is in the unfolded state, the first link 310 gradually extends obliquely upward and leftward from front to rear, and the second link 320 gradually extends obliquely upward and rightward from front to rear, with the side of the first side bracket 100 being the right side and the side of the second side bracket 200 being the left side. As can be seen from the drawings, the first connecting rod 310 and the second connecting rod 320 in the present embodiment do not extend exactly along straight lines, and each of the first connecting rod 310 and the second connecting rod 320 has a plurality of bending turns in the respective axial directions, so that interference generated in the process of rotating and folding the first connecting rod 310 and the second connecting rod 320 can be avoided. Along the left-right direction, the first connecting rod 310 is gradually bent inwards at the first end 311 and the second end 312, and the second connecting rod 320 is gradually bent inwards at the third end 321 and the fourth end 322, so that the first connecting rod 310 and the second connecting rod 320 can be better attached to the first side bracket 100 and the second side bracket 200, and the child stroller has smaller width after being folded. In this embodiment, there is a second virtual plane (not shown in the figure), and the first end 311, the second end 312, the third end 321 and the fourth end 322 all intersect with the second virtual plane, and the first axis 1001, the second axis 1002, the third axis 1003, the fourth axis 1004 and the fifth axis 1005 are perpendicular to the second virtual plane. In this embodiment, when the stroller is in the unfolded state, the second virtual plane gradually extends from front to back in an upward slope, so that the first axes 1001 and the like gradually extend from front to back in a downward slope, respectively.
Referring to fig. 3, in the present embodiment, the first end portion 311 and the fourth end portion 322 are symmetrically disposed about the first virtual plane 101, and the second end portion 312 and the third end portion 321 are symmetrically disposed about the first virtual plane 101. The rotational connection of the first link 310 and the second link 320 intersects the first virtual plane 101, the first end 311 and the second end 312 are symmetrically disposed about the rotational connection, and the third end 321 and the fourth end 322 are symmetrically disposed about the rotational connection, in other words, the first link 310 is rotationally connected at a midpoint position of the second link 320 at a midpoint position thereof. So that the transverse bracket 300 is more symmetrical in the front-back and left-right directions and is more uniformly and stably stressed.
Referring to fig. 1 to 3, the first side bracket 100 includes a first rod and a second rod, the second side bracket 200 includes another set of first rod and second rod symmetrically disposed, the first end 311 is rotatably connected to the first rod of the first side bracket 100, the second end 312 is rotatably connected to the second rod of the second side bracket 200, the third end 321 is rotatably connected to the second rod of the first side bracket 100, and the fourth end 322 is rotatably connected to the first rod of the second side bracket 200. In this embodiment, the second stay 5 is specifically selected to be a first rod, the rear bracket 2 is a second rod, the upper portion of each side of the second stay 5 is rotatably connected to the first link 310 or the second link 320, and the upper end portion of each side of the rear bracket 2 is rotatably connected to the first link 310 or the second link 320. In other embodiments, the first rod and the second rod may be different rods, so that the rigidity of the frame may be enhanced on the premise of not interfering with the integral folding of the stroller. Further, in some embodiments, the first side bracket 100 and the second side bracket 200 may be configured completely different from those of the present embodiment, and those skilled in the art may select the first rod and the second rod for connecting the first link 310 and the second link 320 according to the actual situation. Referring to fig. 1 to 3, in the present embodiment, the upper portion of the second stay 5 of each side has a first connection portion 52 protruding inward in the left-right direction, and the upper end portion of the rear bracket 2 of each side has a second connection portion 23 protruding inward for rotational connection with the corresponding one end portion of the first link 310 or the second link 320.
Referring to fig. 1 and 3, in the present embodiment, the cross bracket 300 further includes a first front rod 330 and a second front rod 340 disposed between the front brackets 1 on both sides, and a first rear rod 350 and a second rear rod 360 disposed between the rear brackets 2 on both sides. One end of the first front rod 330 is rotatably connected to the front bracket 1 of the first side bracket 100, one end of the second front rod 340 is rotatably connected to the front bracket 1 of the second side bracket 200, and the other end of the first front rod 330 is rotatably connected to the other end of the second front rod 340. One end of the first rear lever 350 is rotatably connected to the rear bracket 2 of the first side bracket 100, one end of the second rear lever 360 is rotatably connected to the rear bracket 2 of the second side bracket 200, and the other end of the first rear lever 350 is rotatably connected to the other end of the second rear lever 360. In this way, the first front rod 330 and the second front rod 340 can be rotated relatively to expand and collapse the front brackets 1 on both sides, and the first rear rod 350 and the second rear rod 360 can be rotated relatively to expand and collapse the rear brackets 2 on both sides.
Referring to fig. 1 and 3, in the present embodiment, the cross bracket 300 further includes a holding link 370 disposed between the push rods 4 at both sides. When the stroller is in the unfolded state, the holding connecting rod 370 extends along the left-right direction, the upper part of each push rod 4 on each side gradually bends and extends inwards from bottom to top along the left-right direction, the upper end part of each push rod 4 on each side is rotationally connected with one end part on the same side of the holding connecting rod 370, and the rotation center lines of the two extend along the up-down direction, in particular to be parallel to the axial direction of the main body of the push rod 4, so that the left-right folding of the push rods 4 on both sides and the holding connecting rod 370 can be realized.
Referring to fig. 4 and 5, in the present embodiment, when the stroller is converted from the unfolded state to the folded state, the first side frame 100 and the second side frame 200 are folded synchronously, and the cross frames 300 are folded in the left-right direction, so that the first side frame 100 and the second side frame 200 are close to each other in the left-right direction. The first connecting rod 310 and the second connecting rod 320 rotate around the fifth axis 1005, the first end 311 and the fourth end 322 are close to each other, the second end 312 and the third end 321 are close to each other, and simultaneously the first end 311 and the third end 321 are far away from each other, and the second end 312 and the fourth end 322 are far away from each other. At the same time, the rotational connection of the first front lever 330 and the second front lever 340 moves upward to rotate and fold the two, the rotational connection of the first rear lever 350 and the second rear lever 360 moves upward to rotate and fold the two, and the push rods 4 on both sides rotate backward relative to the holding link 370 and fold each other on the rear side of the holding link 370.
Referring to fig. 4 and 5, in the process of converting the stroller from the unfolded state to the folded state, in each of the first side bracket 100 and the second side bracket 200, the push rod 4 is first driven to move downward, and the push rod 4 rotates forward relative to the first stay 3 to fold, so as to drive the first stay 3 and the second stay 5 to both flip backward and fold toward the rear bracket 2. In this process, the movement of the second stay 5 is transmitted to the front link 6 through the front extension 51, and the front bracket 1 and the rear bracket 2 are drawn toward each other through the front link 6. Meanwhile, because the upper parts of the first stay bar 3 and the second stay bar 5 are relatively far away, the sliding sleeve 8 slides upwards along the seat bar 7 while driving the seat bar 7 to rotate, and the sliding sleeve 8 and the lower extension part 71 of the seat bar 7 are gradually far away, so that the seat bar 7 can be folded between the first stay bar 3 and the second stay bar 5.
The folding process of the first side bracket 100 and the second side bracket 200 counteracts the first connecting rod 310 and the second connecting rod 320 in that the second supporting rod 5 is turned backwards relative to the rear bracket 2, so that the first end 311 of the first connecting rod 310 and the fourth end 322 of the second connecting rod 320 move backwards and downwards, the third end 321 and the second end 312 move upwards relatively, and the first end 311 and the fourth end 322 synchronously move below the third end 321 and the second end 312.
Referring to fig. 6 and 7, in the present embodiment, when the stroller is in a folded state, the first link 310 and the second link 320 extend in the up-down direction, and the front bracket 1, the rear bracket 2, the first stay 3, the push rod 4, the second stay 5, the front link 6, the seat rod 7, and the like on each side also extend in the up-down direction, and are compactly folded together, at this time, the second virtual plane is converted into a gradually downward inclined extension from front to back, the overall length, height, and width of the stroller are significantly reduced, and the front wheel assemblies 11 and the rear wheel assemblies 21 on both sides can be simultaneously supported on the ground, so as to realize folding self-standing.
In summary, the stroller provided in this embodiment has no interference between the rods, so that the stroller can be folded transversely conveniently and quickly, and has a very small folded volume, and the stroller has high structural rigidity and strength in an unfolded state, reduces shaking and jolting of the stroller frame, and has better use experience.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
