Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 4, a stroller comprises a stroller frame and a wheel assembly disposed at the bottom of the stroller frame, wherein the wheel assembly comprises a plurality of sets of wheels 8 connected by a cross rod, the stroller frame comprises two sets of support rods 6 disposed at intervals along the left and right directions, and a shock absorbing assembly disposed on the cross rod and between the two sets of support rods 6 along the left and right directions. Wherein, the stake arm 6 and the horizontal pole can be along the upper and lower direction relatively close to or keep away from ground sliding connection, shock-absorbing component includes two sets of sliders 3 that set up along the length extending direction interval of horizontal pole to and set up the elastic component 2 between two sets of sliders 3, still be provided with the linkage between slider 3 and the stake arm 6 rather than the homonymy, when following relative slip from top to bottom between stake arm 6 and the horizontal pole, the relative horizontal pole of above-mentioned linkage drive slider 3 slides, thereby make the elastic component 2 that is located between two sets of sliders 3 extruded or released.

Specifically, referring to fig. 1 to 4, the cross bar has a bar main body 1 extending in the left-right direction, and two connectors 5 provided on the bar main body 1, the two connectors 5 being provided on both left and right ends of the bar main body 1, respectively, for connecting with two bracket bars 6 on both sides. The wheels 8 are provided with two groups which are respectively arranged at the left side and the right side, and the two wheels 8 are respectively and rotationally connected to the outer side parts of the two connectors 5, so that the installation connection between the wheels and the cross rod is realized.

Each of the coupling heads 5 includes a coupling seat 52 fixedly provided on the lever body 1, and a coupling rod 51 extending upward from the coupling seat 52, the coupling rod 51 being slidably coupled with the bracket bar 6. Here, the support rod 6 and the connecting rod 51 are connected in a sliding sleeve manner, specifically, the connecting rod 51 is slidably inserted into a lower lumen of the support rod 6, and a limiting structure 7 for limiting relative sliding displacement of the support rod 6 and the connecting rod 51 in the vertical direction is further disposed between the support rod 6 and the connecting rod 51. Referring to fig. 2 and 4, the limiting structure 7 includes a limiting groove 72 opened on the support rod 6 and extending in the vertical direction, and a limiting pin 71 disposed on the connecting rod 51, and the limiting pin 71 is slidably disposed in the limiting groove 72.

Referring to fig. 1 to 4, the elastic member 2 is a suspension spring fitted over the rod main body 1 of the cross rod, the sliding member 3 is a compression spring cover slidably fitted over the rod main body 1, and the two compression spring covers are respectively abutted against left and right end portions of the elastic member 2 rightward/leftward. The rod body 1 is further provided with a sliding limiting structure for limiting the sliding displacement of the sliding part 3 on the cross rod, when the sliding limiting structure is specifically arranged, a guide groove 9 extending along the length direction of the sliding part can be formed in the rod body 1, a guide pin (not shown in the figure) which can correspondingly penetrate into the guide groove 9 is arranged on the sliding part 3, and when the sliding part 3 slides left and right along the cross rod, the guide correspondingly slides in the guide groove 9.

In this embodiment, the link member provided between the support rod 6 and the sliding member 3 is a link rod 4, the link rod 4 extends obliquely in the vertical direction, an upper portion thereof is rotatably connected to an inner side portion of the support rod 6 by a pin shaft, and a lower portion thereof is rotatably connected to an upper portion of the sliding member 3 by another pin shaft.

Referring to fig. 5 and 6, a stroller according to an embodiment of the present invention includes a front frame 10 and a rear frame 20, and a wheel assembly including a front wheel 12 disposed at the bottom of the front frame 10 and two sets of rear wheels disposed at the left and right sides of the bottom of the rear frame 20. Wherein, the rear bracket 20 includes two sets of cradling pieces 6 as above and connects the horizontal pole between the cradling pieces 6 of both sides, and wheel 8 is the rear wheel, and this two sets of rear wheels are located on both ends about the horizontal pole respectively.

Thus, when the child stroller bumps during driving, the connecting rods 51 on the two sides move upwards and slide upwards relative to the support rods 6, so that the distance between a rotating point between the connecting rod 4 and the support rods 6 and the cross rod is reduced, the connecting rod 4 rotates to drive the sliding parts 3 to move inwards along the cross rod, and the sliding parts 3 on the two sides move in opposite directions, so that the elastic parts 2 are extruded to be compressed and deformed; then, the sliding parts 3 on both sides are separated from each other under the action of the elastic part 2, so that the connecting rod 4 drives the support rod 6 to slide upwards relative to the connecting rod 51 until the elastic part 2 is reset. In the above process, the elastic member 2 is compressed and deformed to absorb the impact force during bumping, so that the acting force acting on the bracket rod 6 is greatly reduced, and the discomfort of the child sitting on the stroller due to bumping on the road surface is avoided or reduced.

When the left side and the right side of the baby stroller suffer from different jolts, the connecting rods 4 on the two sides drive the sliding parts 3 on the two sides to slide asymmetrically, if only the sliding part 3 on one side slides inwards, or the sliding parts 3 on the two sides slide inwards respectively for different displacements, and the whole shock absorption of the baby stroller is realized.

The novel shock-absorbing structure and the shock-absorbing mode adopted in the children cart are simple in arrangement and obvious in shock-absorbing effect.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to 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 within the protection scope of the present invention.
