DETAILED DESCRIPTION

[0023] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0024] refer to Figure 1-5 The present embodiment provides a baby stroller with a small folded volume, which can be switched between a folded state and an unfolded state. When the baby stroller is in the unfolded state, refer to Figure 1-3 The unfolded height H1 of the baby carriage in the vertical direction is 980-1000 mm, the unfolded width W1 in the left-right direction is 370-400 mm, and the unfolded length L1 in the front-back direction is greater than 450 mm and less than 800 mm; the spacing D1 between the front wheel assembly 13 and the rear wheel assembly 14 of the baby carriage is 450 mm, and the height D2 of the frame mechanism 1 of the baby carriage is 410-420 mm. It can be seen that compared with the existing foldable baby carriages on the market, the baby carriage of this embodiment has a small volume after unfolding, which reduces the space occupied after unfolding.

[0025] When the stroller is in the folded state, refer to Figure 4-5, the folded height H2 of the baby stroller in the vertical direction is 410-430mm, the folded width W2 in the left-right direction is 160-180mm, and the folded length L2 in the front-to-back direction is 160-180mm. In this embodiment, the folded height H2 of the baby stroller in the vertical direction is preferably 420±5mm, the folded width W2 in the left-right direction is preferably 170±5mm, and the folded length L2 in the front-to-back direction is preferably 170±5mm, that is, the volume of the baby stroller after folding is (170±5)mm×(170±5)mm×(420±5)mm. It can be seen that the folded height of the baby stroller in this embodiment is close to the height of the frame mechanism 1 after the baby stroller is unfolded, and compared with the existing foldable baby stroller, its folded volume is very small, which is more convenient and easy to carry.

[0026] refer to Figure 1-5 The baby stroller comprises two frame mechanisms 1, a push rod mechanism 2 and a folding mechanism 3. The two frame mechanisms 1 are arranged relative to each other in the left-right direction. Each frame mechanism 1 is configured to switch between a folded and upwardly contracted state and an unfolded and downwardly extended state. In this way, the frame mechanism 1 itself can be folded and folded and the height can be adjusted, ensuring that the height of the frame mechanism 1 is smaller after the baby bed is folded. The push rod mechanism 2 is arranged at the upper rear of the two frame mechanisms 1, and the lower end of the push rod mechanism 2 is rotatably connected to the upper end of the two frame mechanisms 1, so that the push rod mechanism 2 can be rotated downwardly and folded or rotated upwardly and unfolded relative to the two frame mechanisms 1, ensuring that the push rod mechanism 2 can be rotated downwardly to the rear of the frame mechanism 1 when the baby bed is folded. The folding mechanism 3 is connected between the two frame mechanisms 1 and linked with the push rod mechanism 2. The folding mechanism 3 can drive the push rod mechanism 2 to rotate relative to the two frame mechanisms 1 during the opening and closing movement, and can drive the two frame mechanisms 1 to move relative to each other. The two frame mechanisms 1 move relative to each other and perform lifting and lowering movements at the same time.

[0027] refer to Figure 1-5 Further, each frame mechanism 1 includes a front support assembly 11, a rear support assembly 12, a front wheel assembly 13 and a rear wheel assembly 14. The rear support assembly 12 is arranged behind the front support assembly 11 and below the push rod mechanism 2. The upper end of the rear support assembly 12 is rotatably connected to the upper end of the front support assembly 11 and the lower end of the push rod mechanism 2. The front wheel assembly 13 is fixedly connected to the lower end of the front support assembly 11, and the rear wheel assembly 14 is telescopically connected to the lower end of the rear support assembly 12, so that the rear wheel assembly 14 can perform lifting and lowering movements. The folding mechanism 3 is connected between the two rear support assemblies 12, and is respectively linked to the front support assembly 11, the rear wheel assembly 14 and the push rod mechanism 2, so that the folding assembly 3121 can drive the two frame mechanisms 1 to move relative to each other during the opening and closing movement, and can also drive the front support assembly 11 and the push rod mechanism 2 to rotate relative to the rear support assembly 12, and drive the rear wheel assembly 14 to move up and down.

[0028] In this embodiment, the baby stroller further includes a foldable pedal assembly 15, which is disposed between the front bracket assemblies 11 of the two frame mechanisms 1, and opposite ends of the pedal assembly 15 are rotatably connected to the two front bracket assemblies 11. When the two frame mechanisms 1 move relative to each other, the pedal assembly 15 can be synchronously driven to be folded upward or unfolded downward.

[0029] refer to Figure 1-5 Furthermore, the push rod mechanism 2 includes two telescopic rod assemblies 21 arranged opposite to each other and a foldable handle assembly 22. The lower ends of the two telescopic rod assemblies 21 are respectively rotatably connected to the upper ends of the two rear bracket assemblies 12 and linked to the folding mechanism 3. The upper ends of the two telescopic rod assemblies 21 are respectively rotatably connected to the opposite ends of the handle assembly 22. Therefore, by designing the telescopic rod assembly 21 as a telescopic structure, the push rod mechanism 2 itself can be folded and adjusted in height, ensuring that the height of the push rod mechanism 2 is smaller after the baby bed is folded.

[0030] In this embodiment, a handle locking structure is provided on the handle assembly 22, and the handle locking structure serves as a first lock, so that the handle assembly 22 can be bent upward to be expanded or bent downward to be folded.

[0031] refer to Figure 1-5 Furthermore, the folding mechanism 3 includes a folding assembly 31 and two folding assemblies 32. The opposite ends of the folding assembly 31 are respectively connected to the two rear support assemblies 12 and the two rear wheel assemblies 14, and are used to drive the two frame mechanisms 1 to move relative to each other, and are also used to drive the rear wheel assemblies 14 to move up and down. The two folding assemblies 32 are respectively slidably connected to the two rear support assemblies 12, and each folding assembly 32 is respectively connected to the upper end of the front support assembly 11, the lower end of the telescopic rod assembly 21 of the push rod mechanism 2, and the folding assembly 31. When the folding assembly 32 slides up and down along the rear support assembly 12, it can respectively link the front support assembly 11, the telescopic rod assembly 21 of the push rod mechanism 2, and the folding assembly 31.

[0032] In this embodiment, the folding assembly 31 includes two lifting rods 311, a shearing linkage group 312 and a folding rod group 313. The two lifting rods 311 are escalably arranged between the two rear support assemblies 12, and their lower ends are respectively connected to the two rear wheel assemblies 14, so that the two lifting rods 311 are respectively linked to the two rear wheel assemblies 14, ensuring that the lifting rods 311 can synchronously drive the rear wheel assemblies 14 to rise and fall. The upper ends of the shearing linkage groups 312 are respectively rotatably connected to the upper ends of the two rear support assemblies 12, and the lower ends are respectively connected to the two folding assemblies 32, so that the two folding assemblies 32 can respectively be linked to the shearing linkage groups 312, ensuring that when the folding assemblies 32 slide up and down along the rear support assemblies 12, the shearing linkage groups 312 can drive the two frame mechanisms 4 to move relative to each other. The lower end of the folding rod group 313 is rotatably connected to the lower ends of the two rear bracket assemblies 12, and the upper end is rotatably connected to the upper ends of the two lifting rods 311. In this way, when the two frame mechanisms 4 move relative to each other, the lifting rods 311 can be driven to rise and fall through the folding rod group 313, and the lifting of the lifting rods 311 can simultaneously drive the rear wheel assembly 14 to rise and fall.

[0033] Furthermore, the crib also includes a locking mechanism (not shown in the figure), and a locking mechanism is provided on the rear support assembly 12 of each frame mechanism 1, and the locking mechanism serves as a second lock, and the support assembly 12 and the opening and closing assembly 32 of the folding mechanism 3 are locked or unlocked through the locking mechanism. When the locking mechanism is unlocked, the opening and closing assembly 32 can slide up and down along the rear support assembly 12.

[0034] Further, the locking mechanism is linked with the handle assembly 22 or the telescopic rod assembly 21 of the push rod mechanism 2. When the locking mechanism is linked with the handle assembly 22, the handle assembly 22 can be linked with the locking mechanism when it is bent downward, so that the locking mechanism is unlocked. When the locking mechanism is linked with the telescopic rod assembly 21, the telescopic rod assembly 21 can be pushed downward to retract and the locking mechanism can be linked with the locking mechanism, so that the locking mechanism is unlocked.

[0035] When the crib needs to be folded, first unlock the handle locking structure on the handle assembly 22, then bend the handle assembly 22 downward, and then push the telescopic rod assembly 21 downward to retract, and unlock the linkage locking mechanism while the handle assembly 22 is bent, or unlock the linkage locking mechanism while the telescopic rod assembly 21 is retracted downward; after the locking mechanism is unlocked, as the telescopic rod assembly 21 continues to retract downward, the folding assembly 32 slides downward along the rear support assembly 12 and links with the folding assembly 31, and while the folding assembly 32 slides downward, it drives the push rod mechanism 2 and the front support assembly 11 to rotate downward toward the rear support assembly 12 and fold, and while the folding assembly 31 is folded and folded, it drives the two frame mechanisms 1 to move closer to each other, and drives the rear wheel assemblies 14 of the two frame mechanisms 1 to retract upward. When the crib is fully folded, its volume is (170±5) mm×(170±5) mm×(420±5) mm. Compared with the existing foldable baby stroller whose volume after folding is not less than 290 mm×205 mm×650 mm, the crib of the utility model has a smaller volume after folding, and is more convenient and easy to carry.

[0036] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
