Detailed Description

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

As shown in fig. 1 to 9, the stroller of the present invention includes a stroller frame, a front wheel assembly 4 disposed at a bottom front portion of the stroller frame, and a rear wheel assembly 5 disposed at a bottom rear portion of the stroller frame.

The stroller frame has unfolded and folded positions. The cart frame at least comprises a first rod piece and a second rod piece, and the first rod piece and the second rod piece are connected in a rotating mode. When the cart frame is in the unfolding state, the first rod piece and the second rod piece are relatively fixed. When the stroller frame is folded, the first rod piece and the second rod piece rotate relatively.

In this embodiment, the first rod and the second rod are rotatably connected through a rotational joint, the rotational joint includes a first joint seat 111 fixedly connected to the first rod and a second joint seat 131 fixedly connected to the second rod, and the first joint seat 111 and the second joint seat 131 are rotatably connected through a first shaft 31.

The children's shallow still includes damping structure, and damping structure sets up between first member and second member, and through damping structure's setting, when the folding first member of shallow frame and second member rotate relatively, damping structure provides the resistance, can slow down the relative slew velocity between first member and the second member automatically to make the folding speed of whole shallow frame slow down, need not artificial manual operation, make the folding operation of children's shallow very convenient.

In order to make the appearance structure of the stroller neat and beautiful, the damping structure is preferably arranged in the rotating joint.

Specifically, the damping structure includes a damping member 21 and an elastic member 22, the damping member 21 is slidably disposed in the first joint seat 111, two end portions of the elastic member 22 are respectively disposed on one end portion of the damping member 21 and the first joint seat 111, the elastic member 22 is in a compressed state, and the other end portion of the damping member 21 abuts against the second joint seat 131 under the elastic force of the elastic member 22.

Thus, when the first rod and the second rod rotate relatively when the stroller frame folds, relative movement occurs between the damping member 21 and the second joint seat 131, and due to the abutting action of the damping member 21 on the second joint seat 131, a friction force is generated between the damping member 21 and the second joint seat 131, so that the relative movement between the damping member 21 and the second joint seat 131 is blocked, and the relative movement speed between the damping member 21 and the second joint seat 131 is reduced, even if the relative rotation speed of the first rod and the second rod is reduced.

The second joint seat 131 is provided with a limiting groove 131a, the limiting groove 131a is recessed toward the inside of the second joint seat 131 from one end of the second joint seat 131 adjacent to the first joint seat 111, the limiting groove 131a extends along the circumferential direction of the first joint seat 111 and the second joint seat 131, and the other end of the damping member 21 abuts against the bottom of the limiting groove 131 a. When the first rod and the second rod rotate relatively when the stroller frame is folded, the damping member 21 moves along the length extending direction of the limiting groove 131 a.

The depth of the limiting groove 131a can be set as required to adjust the magnitude of the abutting force of the damping member 21 acting on the second joint seat 131, so as to adjust the magnitude of the friction force between the damping member 21 and the second joint seat 131, and further adjust the rotation speed between the first rod and the second rod.

When the depth of the limiting groove 131a is deeper, the degree of compression of the elastic element 22 is relatively smaller, so that the abutting force of the damping element 21 acting on the second joint seat 131 is relatively smaller, the friction force generated between the damping element 21 and the second joint seat 131 during the relative movement of the damping element 21 and the second joint seat 131 is also smaller, and the degree of slowing down the relative rotational speed of the first rod and the second rod is also smaller. On the contrary, when the depth of the limiting groove 131a is smaller, the degree of compression of the elastic element 22 is relatively larger, so that the abutting force of the damping element 21 acting on the second joint seat 131 is relatively larger, the friction force generated between the damping element 21 and the second joint seat 131 during the relative movement of the damping element 21 and the second joint seat 131 is also larger, and the degree of slowing down the relative rotational speed of the first rod and the second rod is also larger.

In this embodiment, the sliding direction of the damping member 21 relative to the first joint base 111 is parallel to the extending direction of the axial line of the first shaft 31.

The first joint seat 111 is provided with a guide groove 111a, the guide groove 111a is engaged with the damping member 21, the extension direction of the guide groove 111a is parallel to the extension direction of the axial line of the first shaft 31, the damping member 21 and the elastic member 22 are both disposed in the guide groove 111a, and the damping member 21 is slidably disposed along the longitudinal extension direction of the guide groove 111 a.
