[0023] The following will make a detailed description of the implementation manners of the present utility model in conjunction with the accompanying drawings.

[0024] As Figures 1 to 6 shown, the present utility model discloses a foldable baby carriage that can stand after being folded, including a leg frame assembly 1 and a push rod assembly 2 rotatably connected to the leg frame assembly 1. The push rod assembly 2 includes a handle 21 and a connecting rod 22 with one end rotatably connected to the leg frame assembly 1 and the other end rotatably connected to the handle 21. The baby carriage further is provided with a support rod 3 with the lower part rotatably connected to the leg frame assembly 1. A sliding member 4 capable of sliding along the support rod 3 is arranged on the support rod 3. The sliding member 4 is rotatably connected to the connecting rod 22. When the leg frame assembly 1 and the push rod assembly 2 rotate relative to each other, the connecting rod 22 can drive the sliding member 4 to slide along the support rod 3, thereby driving the support rod 3 to rotate to form a standing support structure with the leg frame assembly 1.

[0025] In the embodiment, the leg frame assembly 1 includes a front leg frame and a rear leg frame rotatably connected to the front leg frame. The front and rear wheels are connected through the front leg frame and the rear leg frame, so as to realize the stable movement of the baby carriage. The push rod assembly 2 is used to control the direction and movement of the baby carriage. The handle 21 and the leg frame assembly 1 are connected through the connecting rod 22, so that the user can push or pull the baby carriage through the handle 21. The sliding member 4 is installed on the support rod 3 and rotatably connected to the connecting rod 22. When the leg frame assembly 1 and the push rod assembly 2 rotate relative to each other, the sliding member 4 will slide on the support rod 3, prompting the support rod 3 to rotate. The support rod 3 will act through the sliding member 4. Thus, when the baby carriage rotates to the folded state, the free end of the support rod 3 can form a support structure together with the front wheel and / or the rear wheel of the leg frame assembly 1 to support the baby carriage to stand stably.

[0026] Through the arrangement that the connecting rod 22 can drive the sliding member 4 to slide along the support rod 3, thereby driving the support rod 3 to rotate to form a standing support structure with the leg frame assembly 1, the baby carriage can be vertically stored through the cooperation of the support rod 3 and the leg frame assembly 1, improving the convenience of storage.

[0027] A limiting mechanism 5 capable of restricting the sliding of the sliding member 4 is arranged on the support rod 3. The push rod assembly 2 is provided with an unlocking mechanism 6 capable of releasing the sliding restriction of the limiting mechanism 5 on the sliding member 4 when the handle 21 and the connecting rod 22 rotate relative to each other.

[0028] The limiting mechanism 5 can fix the position of the sliding member 4 and maintain the stability of the stroller in the non-folded state. The unlocking mechanism 6 enables the user to release the restriction of the limiting mechanism 5 on the sliding member 4 by the relative rotation of the handle 21 and the connecting rod 22 when folding the stroller, so that the support rod 3 and the leg assembly 1 cooperate to form a stable standing support structure.

[0029] The limiting mechanism 5 includes a limiting block 51 that can limit the sliding of the sliding member 4 and a receiving groove 52 that can receive the limiting block 51. The limiting block 51 is connected with a reset member 53 that presses the limiting block 51 away from the receiving groove 52.

[0030] When the limiting block 51 is in the working position, it can limit the sliding of the sliding member 4 on the support rod 3, thereby ensuring the stability of the stroller in the non-folded state. When the limiting block 51 is not required to limit, the limiting block 51 can be received into the receiving groove 52, enabling the sliding member 4 to slide along the support rod 3. In the embodiment, the reset member 53 is a reset spring, and the reset member 53 can also be other elastic elements. The reset member 53 presses the limiting block 51 away from the receiving groove 52 to keep it in the working position, realizing the limitation of the position of the sliding member 4. The limiting block 51, the receiving groove 52, and the reset member 53 constitute a reliable mechanical locking system to ensure the stability of the stroller.

[0031] The unlocking mechanism 6 includes a linkage member 61 and a first inclined surface 62 provided on the handle 21 that can push the linkage member 61 when the handle 21 and the connecting rod 22 rotate relative to each other, causing the linkage member 61 to drive the limiting block 51 into the receiving groove 52.

[0032] The linkage member 61 can convert the relative rotation between the handle 21 and the connecting rod 22 into a force on the limiting block 51. The first inclined surface 62 is provided on the handle 21. When the handle 21 and the connecting rod 22 rotate relative to each other, the first inclined surface 62 presses the linkage member 61 to move, thereby driving the limiting block 51 into the receiving groove 52. The unlocking mechanism 6 is composed of the linkage member 61 and the first inclined surface 62, with high reliability and durability. The user only needs to rotate the handle 21 to unlock the limiting mechanism 5, and the operation is simple. Through the design of the first inclined surface 62, the unlocking process is smoother, reducing jamming and wear.

[0033] A first rotating seat 211 is provided on the handle 21, a second rotating seat 221 rotatably connected to the first rotating seat 211 is provided on the connecting rod 22, the second rotating seat 221 is rotatably connected to the sliding member 4, the linkage member 61 is provided in the second rotating seat 221, the first inclined surface 62 is provided on the first rotating seat 211, and an outlet 2211 is formed on the second rotating seat 221 for the linkage member 61 to extend out and cooperate with the first inclined surface 62.

[0034] Through the arrangement of the first rotating seat 211 and the second rotating seat 221, the two are rotationally connected, so that the handle 21 can rotate relative to the connecting rod 22. The connecting rod 22 is arranged in the second rotating seat 221 and extends out of a partial part through the extending port 2211. When the handle 21 and the connecting rod 22 rotate relative to each other, a partial part of the first inclined surface 62 presses the linkage member 61, causing it to move and drive the limiting block 51 into the receiving groove 52, thereby releasing the restriction on the sliding member 4. Through the arrangement of the first rotating seat 211 and the second rotating seat 221, the unlocking mechanism 6 is integrated in the rotating seat, with a compact structure.

[0035] The limiting block 51 is provided with a second inclined surface 511 that can be pushed by the sliding member 4 so that the limiting block 51 moves in the direction close to the receiving groove 52.

[0036] When the sliding member 4 moves and contacts the second inclined surface 511, the second inclined surface 511 can enable the sliding member 4 to exert a force on the limiting block 51, forcing the limiting block 51 to enter the receiving groove 52, thereby allowing the sliding member 4 to continue to move to the locking position. The limiting block 51 returns to the working position under the action of the reset member 53 to lock the sliding member 4.

[0037] The limiting mechanism 5 has other implementation manners, such as being connected by a mechanical buckle or a magnetic attraction connection, and can also realize the restriction on the sliding of the sliding member 4; the unlocking mechanism 6 has other implementation manners, such as a gear system or a linkage mechanism, and can also generate corresponding actions when the user operates the handle 21 to rotate, thereby unlocking the limiting mechanism 5.

[0038] The upper part of the support rod 3 is provided with an anti-slip member 31 that can abut against the ground after the baby carriage is folded.

[0039] The anti-slip member 31 can be made of an anti-slip material. After the baby carriage is folded, the support rod 3 will rotate to an inclined angle, so that the anti-slip member 31 contacts the ground. Through the arrangement of the anti-slip member 31, additional stability is provided to ensure that the baby carriage can stand firmly after being folded and prevent the baby carriage from sliding or tipping due to slight external forces in the folded standing state.

[0040] The support rod 3 is provided with a hollow interior. The anti-slip member 31 has an insertion portion 311 extending into the support rod 3. The receiving groove 52 is arranged in the insertion portion 311. The support rod 3 is provided with a limiting port 32 for the limiting block 51 to extend out.

[0041] The insertion part 311 is located at one end of the anti-slip member 31 and can extend into the hollow part of the support rod 3, thereby fixing the anti-slip member 31 on the support rod 3. In the embodiment, the receiving groove 52 is provided in the insertion part 311 of the anti-slip member 31, and the reset member 53 is provided between the receiving groove 52 and the limiting block 51, so that the insertion part 311 can integrate the limiting mechanism 5, making the structure compact. The limiting opening 32 is opened on the support rod 3. The limiting block 51 is allowed to extend out when needed to limit the movement of the sliding member 4.

[0042] The anti-slip member 31 has a limiting part 312 that can limit the sliding member 4 from detaching from the end of the support rod 3.

[0043] Through the arrangement of the limiting part 312, the sliding member 4 is restricted from detaching from the end of the support rod 3, ensuring that the sliding member 4 always slides on the support rod 3 and will not accidentally come out, increasing the safety and reliability of the system.

[0044] The sliding member 4 is a sliding sleeve sleeved on the support rod 3.

[0045] The sliding member 4 is an annular or cylindrical sliding sleeve, and the inner hole diameter is slightly larger than the diameter of the support rod 3 for easy sliding. Through the arrangement of the sliding member 4 as an annular or cylindrical sliding sleeve, the stability of the sliding member 4 is improved.
