In this example, the locking mechanism for locking the cart frame in the unfolded state is not a design point of the present invention, and the prior art can be used, which is not limited in the present invention.

How the stroller works:

Referring to Figures 1 to 3, the stroller is in the unfolded state and the push rod 1 is in a forward-use state, the push rod 1, the front bracket 2 and the rear bracket 3 are relatively unfolded, and the push rod 1 extends obliquely from bottom to top along the front and rear directions of the stroller It is arranged that the second rotating shaft 7 is located at the first end M of the first limiting groove 14 and the second end N of the second limiting groove 15 respectively, and the three are in contact with each other, and the first pin 8 is located at the first chute 10 and The intersection of the first escape grooves 12 , that is, the first pin shaft 8 is located at the first intersection point P, and the second pin shaft 9 is located in the second escape groove 13 .

When the stroller needs to be folded, unlock the locking mechanism, push down the push rod 1 and drive the push rod 1 to rotate toward the rear bracket 3 around the second rotating shaft 7, see Figures 4-6, during the rotating process, the second rotating shaft 7 moves along the The length direction of the first limiting slot 14 slides in the first limiting slot 14 and the second rotating shaft 7 is always in contact with the second end N of the second limiting slot 15 , and the first pin 8 is connected by the first intersection P. The position slides down into the first chute 10, and at the same time abuts against the side wall of the first chute 10 and rotates relatively, thereby driving the first connecting seat 2b to rotate relative to the second connecting seat 3b around the first rotating shaft 6, that is, the front bracket 2 The second pin shaft 9 slides in the second avoidance groove 13 along the length direction of the second avoidance groove 13, that is, when the push rod 1 rotates and moves closer to the rear supporter 3, the front supporter is linked. 2 Rotate the rear bracket 3 closer, and finally complete the folding. After the folding is completed, referring to FIGS. 7-9 , the stroller is in the first folded state, the push rod 1 and the rear bracket 3 are located on the rear side of the front bracket 2 in the front-rear direction, and the push rod 1 is located behind the rear bracket 3 . When unfolding, the reverse operation can be used, that is, the push rod 1 can be rotated upward relative to the rear bracket 3 to unfold, and the front bracket 2 can be rotated and unfolded relative to the rear bracket 3 until the stroller is fully unfolded, and then the locking mechanism is locked, and the unfolding is completed. , the operation is very simple.

When the stroller is in the unfolded state and the push rod 1 needs to be reversed, if the push rod 1 is changed from forward use to reverse use, it is only necessary to unlock the locking mechanism, and move the push rod 1 around the second axis of rotation 7. The front bracket 2 of the stroller can be rotated in the direction. During the rotation, the second rotating shaft 7 is always located at the first end M of the first limiting slot 14, the second end N of the second limiting slot 15, and the three As a result, the first pin 8 rotates into the first avoidance groove 12 , and the second pin 9 rotates in the second avoidance groove 13 to the intersection of the second avoidance groove 13 and the second chute 11 , that is, the second pin 9 Rotate to the position of the second intersection Q, lock the locking mechanism, and complete the reversal of the push rod 1, as shown in Figures 10-12.

The two pin shafts 9 slide down into the second chute 11 from the position of the second intersection Q, and at the same time abut against the side wall of the second chute 11 and rotate relative to each other, thereby driving the second connecting base 3b around the first rotating shaft 6 to be relative to the second When the connecting seat 2b rotates, that is, the rear bracket 3 rotates around the first rotating shaft 6 relative to the front bracket 2, and the first pin shaft 8 slides in the first avoidance groove 12 along the length direction of the first escape groove 12, that is, the push rod 1 is opposite to the first escape groove 12. When the front bracket 2 is rotated and moved closer, the linked rear bracket 3 is rotated and moved closer to the front bracket 2, and the folding is finally completed. 16-18, the stroller is in the second folded state, the push rod 1 and the front bracket 2 are located on the front side of the rear bracket 3 in the front-rear direction, and the push rod 1 is located in front of the front bracket 2. When unfolding, the reverse operation can be used, that is, the push rod 1 can be rotated upward relative to the front bracket 2 to unfold, and the linked rear bracket 3 can be rotated and unfolded relative to the front bracket 2 until the stroller is fully unfolded, and then the locking mechanism is locked, and the unfolding is completed. , the operation is very simple.

Whether the installation is reversed or reversed, the push rod 1 can be reversed and the stroller can be folded, and the folding of the stroller will not be disturbed by the seat pocket frame 200 .

22 to 23 , the push rod 1 is used in the forward direction, and the seat pocket frame 200 is installed in the forward direction. When it needs to be folded, the push rod 1 is unlocked, the push rod 1 is pressed down, and the push rod 1 is rotated and moved closer to the rear bracket 3 , the front bracket 2 is linked to rotate towards the rear bracket 3, and finally the folding of the stroller frame 100 is completed. The cart is shown in Figures 24~25.

Referring to Figures 26-27, the push rod 1 is used in the reverse direction, and the seat pocket frame 200 is installed in the forward direction. When it needs to be folded, unlock the cart frame 100, push the push rod 1 down and make the push rod 1 rotate relative to the front bracket 2. After the linkage The bracket 3 is rotated and moved closer to the front bracket 2, and finally the folding of the stroller frame 100 is completed. As shown in Figures 28~29.

30 to 31, the push rod 1 is used in the forward direction, and the seat pocket frame 200 is installed in the reverse direction. When it needs to be folded, unlock the cart frame 100, press the push rod 1 downward and make the push rod 1 rotate towards the rear bracket 3, and the linkage The front bracket 2 is rotated toward the rear bracket 3, and finally the folding of the stroller frame 100 is completed. As shown in Figures 32~33.

34~35, the push rod 1 is used in reverse, and the seat pocket frame 200 is installed in the reverse direction. When it needs to be folded, unlock the cart frame 100, press the push rod 1 down, and make the push rod 1 rotate towards the front bracket 2. The rear bracket 3 is rotated and moved closer to the front bracket 2, and finally the folding of the stroller frame 100 is completed. As shown in Figures 36~37.

In a word, through the above arrangement, the push rod 1 can be folded and unfolded in linkage when it is used in the forward direction and in the reverse direction, and the push rod 1 can be pushed in both the forward and reverse use.
