There are two lock holes, when the reversing stroller is in the forward use state and the reverse use state, the lock pin is inserted into the different lock holes. When the second locking mechanism is unlocked, that is, the lock pin is released from a lock hole, and the push rod assembly 21 rotates forward, the first sliding member 24 slides relative to the lower push rod 211. When a locking mechanism is unlocked, the first sliding member 24 slides relative to the lower push rod 211 to the position where the locking pin corresponds to the other locking hole, the locking pin is inserted into the locking hole under the action of the elastic force of the elastic member, and the second locking mechanism i.e. locked.

The specific structure of the first locking mechanism may adopt the structure in the prior art, and the structure for driving the unlocking of the first locking mechanism and the specific structure of the second locking mechanism are not limited to the structures given in this embodiment.

When the reversing stroller is in a forward use state and the second locking mechanism is unlocked, the upper bracket 2 can also be folded.

In this embodiment, a specific structure of the bottom bracket 1 is given. Of course, the bottom bracket 1 is not limited to the structure given in this embodiment.

Specifically, the bottom bracket 1 includes a front bracket 11 , a rear bracket 12 and a lower connecting member 13 . The front wheel assembly 3 is arranged at the lower part of the front bracket 11 , and the rear wheel assembly 4 is arranged at the lower part of the rear bracket 12 . The front bracket 11 and the rear bracket 12 are respectively disposed on the left and right sides of the stroller, and the lower connecting member 13 is connected between the front bracket 11 or the rear bracket 12 on the left and right sides. On each side of the left and right sides, the upper part of the front bracket 11, the upper part of the rear bracket 12 and the left end part or the right end part of the three parts of the lower part of the connecting piece 13 are connected in rotation, and the third part is connected with the above two parts. Any one of the components is rotationally connected, or the above three components are rotationally connected coaxially.

In order to facilitate the folding operation of the stroller, the bottom bracket 1 further includes a front strut 14 and a side strut 15 . The front strut 14 is rotatable relative to the front bracket 11 and slidably disposed along the lengthwise extending direction of the front bracket 11 , and the front strut 14 is rotatably connected to the lower connecting piece 13 . One end of the side stay 15 is rotatably provided relative to the front bracket 11 and slid along the lengthwise extending direction of the front bracket 11 , and the other end of the side stay 15 is rotatably connected to the rear bracket 12 .

The bottom bracket 1 further includes a second sliding member 16 , which is slidably disposed on the front bracket 11 along the lengthwise extending direction of the front bracket 11 , and three components: the front strut 14 , one end of the side strut 15 and the second sliding member 16 . The middle two components are rotatably connected, and the third component is rotatably connected with any one of the above two components, or the above three components are coaxially rotatably connected.

In this embodiment, the upper part of the front bracket 11 , the upper part of the rear bracket 12 , and the left or right end of the lower connecting piece 13 are connected in a coaxial rotation. The three parts of the slider 16 are connected in a coaxial rotation. In this way, a crank-slider mechanism is formed between the front bracket 11 , the rear bracket 12 , the side stay 15 and the second sliding piece 16 , and the front bracket 11 , the lower connecting piece 13 , the front stay 14 and the second sliding piece 16 A crank-slider mechanism is also formed in between.

In this embodiment, the side struts 15 are respectively disposed on the left and right sides of the stroller. The front strut 14 extends in the left-right direction, and the left and right ends of the front strut 14 are respectively rotatable relative to the front bracket 11 on the corresponding side and slidably arranged along the lengthwise extending direction of the front bracket 11 . The connecting piece 13 is rotatably connected.

The reversing stroller also includes a third locking mechanism for locking the relative position of the bottom bracket 1. When the reversing stroller is used in a forward use state and a reverse use state, the third locking mechanism is locked. state. When the third locking mechanism is unlocked, the bottom bracket 1 can be folded. The specific structure of the third locking mechanism and the unlocking structure that drives the third locking mechanism to be unlocked can all be those in the prior art.

When the reversing stroller is in a forward use state, the first locking mechanism, the second locking mechanism and the third locking mechanism are all in a locked state, as shown in FIG. 1 and FIG. 2 .

When the stroller is in a reverse use state, the first locking mechanism, the second locking mechanism and the third locking mechanism are also in a locked state, as shown in FIG. 3 and FIG. 4 .

When the stroller is switched from the forward use state to the reverse use state, the second locking mechanism is first unlocked. After the second locking mechanism is unlocked, the push rod assembly 21 can rotate forward relative to the seat 23, and the push rod assembly 21 moves forward. When turning over, the first sliding member 24 slides upward along the lengthwise extending direction of the lower push rod 211. When the push rod assembly 21 is rotated forward by a certain angle, the first locking mechanism is unlocked and the second locking mechanism is locked again, that is, the upper bracket 2 is formed. as a whole, as shown in Figures 5 and 6.

Rotate the upper bracket 2 relative to the bottom bracket 1 around the rotation axis 5. As shown in Figures 7 and 8, when the upper bracket 2 is rotated about 180 degrees relative to the bottom bracket 1 around the rotation axis 5, the first locking mechanism is locked again, and the direction is reversed. The operation is complete.

When the stroller is converted from the reverse use state to the forward use state, the second locking mechanism is also unlocked first. After the second locking mechanism is unlocked, the push rod assembly 21 can be rotated forward relative to the seat 23, and the push rod assembly 21 can rotate toward the seat 23. During the front flip, the first sliding member 24 slides down along the lengthwise extending direction of the lower push rod 211 , and the rest is the same as the process of switching the reversing stroller from the forward use state to the reverse use state.

When the reversing baby stroller is in the forward use state, the reversing baby stroller can also be folded. When folded, the lock between the push handle 212 and the lower push rod 211 is first unlocked, and the push handle 212 is rotated backward. Move closer to the lower push rod 211; after unlocking the first locking mechanism, the second locking mechanism and the third locking mechanism, turn the push rod assembly 21 forward and move closer to the seat 23, and drive the first sliding member 24 to push down along the The longitudinal extension direction of the rod 211 slides upward, and drives the upper strut 22 to rotate and move closer to the push rod assembly 21; When sliding down, the front support 11 is driven by the front support rod 14 to rotate forward relative to the lower connecting piece 13 to be close to the seat 23, and the side support rod 15 is used to drive the rear support 12 to turn forward and move closer to the front support 11. The folding process As shown in Figures 9 and 10, until the components that make up the cart frame are close together, the final fold is shown in Figure 11.
