Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1 to 6, a baby carriage, in this example, the baby carriage is a baby walker for infants to walk. The frame includes side brackets located on both sides, a support base 30 located between the side brackets on both sides and rotatably arranged relative to the side brackets, and connected between the upper ends of the first brackets 10 on both sides for the baby's hand support. The side brackets include a first bracket 10 on which the front wheel assembly 100 is installed, and a second bracket 20 on which the rear wheel assembly 200 is installed and is rotatably arranged around the first bracket 10, wherein the first bracket 10 is in the up-down direction. The second bracket 20 extends along the front-rear direction of the frame, the rotation axis of the second bracket 20 extends along the extension direction of the first bracket 10, and the rotation axis of the support seat 30 is along the left-right direction of the frame extend.

In this example, the side stand has a first use state and a second use state, and the support base 30 has a first position and a second position, and when the side stand is in the first use state or the second use state, the second support 20 are respectively located on opposite sides of the first bracket 10 in the front-rear direction.

Specifically, as shown in FIG. 1 , when the side bracket is in the first use state and the support base 30 moves to the first position, the free ends of the second brackets 20 on both sides are close to each other, and the support base 30 extends along the front-rear direction. , and the bottom of the support seat 30 is built on the second brackets 20 on both sides, and the upper surface of the support seat 30 constitutes the seating surface for the infant to ride; In this state, the baby can sit on the upper surface of the support seat 30, face the side where the first bracket 10 is located, put his feet on the ground and hold the handrail 40 with his hands to ride and play. Children who have learned to walk can use it as a toy car for riding and playing in this riding state.

As shown in FIG. 4 and FIG. 5 , when the side bracket is in the second use state and the support base 30 moves to the second position, the free ends of the second brackets 20 on both sides are away from each other, and the support base 30 extends in the up-down direction. And it is folded between the first brackets 10 on both sides; that is, at this time, the baby walker is in a pushing use state. In the space, the baby stands between the second brackets 20 on both sides, faces the side where the first bracket 10 is located, and holds the handrail 40 to walk. In addition, when the baby walker is in the push state, some instruments for children to play with (see FIG. 5 ) can be arranged on the opposite side of the seating surface of the support base 30 to enhance the playability of the baby walker.

In this example, the first brackets 10 on both sides include an upper rod body 101 , a lower rod body 102 and a connecting shaft 103 that is rotatably or fixedly connected between the upper rod body 101 and the lower rod body 102 . The upper end of the upper rod body 101 is connected to the handrail 40 Fixed connection, the lower ends of the lower rod bodies 102 on both sides are rotatably connected with the front wheel assembly 100 through a front wheel shaft 1001; the second brackets 20 on both sides are composed of an arc-shaped arc rod, one end of the arc-shaped rod is The other end of the arc rod is rotatably connected to the connecting shaft 103 through the rear wheel shaft 2001 respectively. The support seat 30 includes a seat body 301, which is bent and extended to one side from the head of the seat body 301. The tongue body 302 (when the baby sits on the support seat 30, the side facing the head is the head, and the side facing the back is the tail), and the two sides of the head of the seat body 301 are connected to the upper rod body through the pin shaft 104. 101 turn connection,

Further, the frame is also provided with a first locking mechanism for locking the side bracket in the first use state and stabilizing the support seat 30 in the first position, for locking the side bracket in the second use state and for locking the support seat 30 A second locking mechanism stabilized in the second position.

The first locking mechanism includes a first engaging portion on both sides of the support base 30, a first engaging portion on the second bracket 20 on both sides and engaging with the first engaging portion. The first engaging portion It is composed of convex columns s11 arranged on both sides of the lower part of the tail of the seat body 301, and the first matching part is composed of a circular groove s12 opened in the middle of the arc-shaped rod;

The second locking mechanism includes second engaging portions disposed on both sides of the support base 30, second engaging portions disposed on the second bracket 20 on both sides for engaging with the second engaging portions, and second engaging portions on both sides of the second bracket 20. The clamping parts are respectively composed of raised parts s21 formed on both sides of the tongue body 302, and a seat ear s20 is also formed at the end of the second bracket 20 (arc-shaped rod) close to the first bracket 10, and the seat ear s20 is provided with a seat ear s20. The groove s22 that is engaged with the raised part s21 and the second matching part is formed by the groove s22.

The baby walker side bracket of the present invention is switched from the first use state to the second use state, and the action process when the support seat 30 moves from the first position to the second position is described as follows:

As shown in FIGS. 1 to 4 , first lift the support base 30 up from the first position and make the protruding post s11 separate from the circular groove s12 (just lift up to make the protruding post s11 separate from the circular groove s12 , there is no need to lift the support base 30 ). completely turned to the second position), at this time the first locking mechanism is unlocked; then the second brackets 20 (arc-shaped rods) that are close to each other on both sides are opened to the outside and rotated around the first bracket 10 in the horizontal direction to the first On the other side of the bracket 10, keep a certain distance between the second brackets 20 on both sides, so as to provide a space for children to stand, and then continue to flip the support seat 30, so that the raised part s21 on the two sides is connected to the first bracket 30. The grooves s22 on the ears s20 of the two brackets 20 are correspondingly snapped together. At this time, the side brackets are in the second use state, and the support base 30 moves to the second position.

The side bracket of the baby walker of the present invention is switched from the second use state to the first use state, and when the support seat 30 moves from the second position to the first position, the operation is the opposite of the above operation, which will not be repeated here.

To sum up, the stroller of the present invention has few components, simple and compact structure, and has two usage states, which can be switched according to needs. In the second use state, it can provide protection for infants and children to stand and learn to walk. Due to the structural design of the changeable state of use, the stroller is more interesting and has a better use experience. After the baby gradually grows up, it can still be used as a The toy car continues to be retained, and the utilization value is greatly improved.

The present invention has been described in detail above, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and cannot limit the scope of protection of the present invention by this, and the present invention is not limited to the above-mentioned embodiments, All equivalent changes or modifications made according to the spirit of the present invention should be included within the protection scope of the present invention.
