Detailed ways

As shown in the drawings, a stroller for children includes a stroller frame 1 with an unfolded position and a folded position, a front wheel assembly 3, a rear wheel assembly 4, a seat device arranged on the stroller frame 1, and a The frame locking mechanism for locking the stroller frame 1 in the unfolded position.

Cart frame 1 includes:

Front support 11, front wheel assembly 3 is arranged on the bottom of front support 11;

Rear support 12, rear wheel assembly 4 is arranged on the bottom of rear support 12, and the upper part of rear support 12 and the top of front support 11 are connected around the first shaft 21 rotation;

Reversing rotating seat 15, reversing rotating seat 15 is connected with the top of front support 11 in rotation;

Front bracket slider 16, the front bracket slider 16 is slidably arranged on the front bracket 11 along the up and down length direction of the front bracket 11;

Folding link 13, the rear part of the folding link 13 is connected with the rear support 12 around the third axis 23, and the front part of the folding link 13 is connected with the front support slider 16 around the second axis 22;

Reversing slide 17, reversing slide 17 is arranged on the folding connecting rod 13 slidingly along the forward and backward direction of folding connecting rod 13, and reversing sliding 17 is also along the rotation center of reversing rotating seat 15 as the center of circle. The circumferential direction of the slide is set on the folding link 13;

The push rod frame 14, the push rod frame 14 is slidably arranged on the reversing rotating seat 15 and the reversing slider 17, and the push rod frame 14 has a forward push state in which the upper part falls backward and a reverse push state in which the upper part falls forward. In the forward pushing state, the pusher and the child sitting in the car face the same direction, which is convenient for the child to see the scenery. In the reverse push state, the pusher is face to face with the child sitting in the car, which is convenient for interaction and communication.

The frame locking mechanism includes a first locking mechanism disposed between the front bracket slider 16 and the front bracket 11 . The specific structure of the first locking mechanism is not the gist of the present invention, as long as it is a structure capable of locking between two sliding parts, it can be applied here. For example, it may include a lock tongue arranged on the front bracket along the lateral sliding of the front bracket 11, and a lock hole provided on the front bracket slider 16. When locking, the elastic member presses the lock tongue to make it stably inserted into the lock hole. Inside, the front bracket slider 16 and the front bracket 11 are prohibited from sliding. The first locking mechanism includes an unlocking touch button, which can slide and touch the dead bolt to unlock it. Or the first locking mechanism includes an unlocking button arranged on the front bracket slider 16 and a lock hole provided on the front bracket 11 .

The push rod frame 14 is provided with an unlocking protrusion that presses the unlocking button when the push rod frame 14 is in a forward pushing state and slides downward relative to the reversing slider 17 . When the push rod frame 14 slides downward, the unlocking convex part presses the unlocking contact button, which can unlock the first locking mechanism.

The vehicle frame locking mechanism also includes a second locking mechanism that prevents the push rod frame 14 from sliding relative to the reversing rotating base 15 and the reversing sliding member 17 . The second locking mechanism is arranged between the push rod frame 14 and the reversing rotating seat 15 , or between the push rod frame 14 and the reversing sliding member 17 . Likewise, the specific structure of the second locking mechanism is not the gist of the present invention, as long as it is a structure capable of locking between two sliding parts, it can be applied here.

The frame locking mechanism includes a third locking mechanism for locking the push rod frame 14 in a forward pushing state or a reverse pushing state. The third locking mechanism can be arranged between the reversing rotating seat 15 and the front bracket 11, that is, it can lock between the two rotating parts. Or it is arranged between the reversing sliding member 17 and the folding link 13, as long as it is a structure capable of locking between two sliding parts, it can be applied here. Or be arranged between the reversing slider 17 and the front bracket slider 16 and the rear bracket 12, that is, under the forward push state, the reversing slider 17 and the front bracket slider 16 are hooked and locked by hooks, spring tongues, etc., and in the reverse push state Next, the reversing slider 17 and the rear bracket 12 are hooked and locked by hooks, elastic tongues, etc.

In this embodiment, the reversing rotating seat 15 is connected with the upper part of the front bracket 11 in rotation around the reversing shaft 24 , and the reversing shaft 24 is located in front of the first shaft 21 . Or the reversing rotating seat 15 and the front bracket 11 are also rotatably connected through the first shaft 21 , that is, the reversing shaft and the first shaft 21 are coaxial.

The seat device includes a seat frame, a seat arranged on the seat frame, and the seat frame is arranged on the front support sliding member 16 .

The push rod frame 14 unlocks the third locking mechanism during the conversion process between the forward push state and the reverse push state, the cart frame 14 rotates around the reversing shaft 24, and the reversing slider 17 slides along the folding connecting rod 13, so that The push rod frame 14 is converted under the forward push state and the reverse push state.

When the stroller frame needs to be folded, the push rod frame 14 is placed in the forward push state, the second locking mechanism is unlocked, the push rod frame 14 is slid downward, and the first locking mechanism is unlocked during the sliding process, so that the front The bracket slider 16 slides relative to the front bracket 11, so that the lower part of the push rod frame 14 together with the front wheel assembly 3 forms a support for the stroller frame, forming a folded self-standing. And the seat device is lowered accordingly, and the volume is smaller after being folded.

Not shown, about the connection of push rod frame 14, also can be another structure, as the bottom of push rod frame 14 is directly connected with the top of front frame 11 or the top of rear frame 12 in rotation. When the trolley frame was folded, the push rod frame 14 turned forward or backward.

As mentioned above, we have fully described according to the purpose of the present invention, but the present invention is not limited to the above-mentioned embodiments and implementation methods. Practitioners in the relevant technical fields may make various changes and implementations within the scope permitted by the technical ideas of the present invention.
