[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a child stroller comprising a seat assembly and a frame 100. The seat assembly is detachably connected to the frame 100. When the seat assembly is not installed on the frame 100, a car seat assembly can be installed on the frame 100. The car seat assembly can be a baby carrier for a child. The ability to install both the seat assembly and the car seat assembly on the frame 100 makes the stroller suitable for children of different ages, enhancing its flexibility.

[0048] The frame 100 includes a base frame 1, which includes a first side frame 11 and a second side frame 12. A support arm 13 is connected between the first side frame 11 and the second side frame 12. The support arm 13 is recessed downward as a whole to form an escape space for evading a seat pocket assembly or a car seat assembly, thereby lowering the installation position of the seat pocket assembly or the car seat assembly so that the seat pocket assembly or the car seat assembly will not interfere with the structure of the frame 100 placed above the seat pocket assembly or the car seat assembly, thereby improving the convenience of using the child stroller.

[0049] In some embodiments, the vehicle frame 100 further includes a support frame 2, which is disposed on the base frame 1 and has a support frame connection portion 21 for connecting to a seat assembly or a car seat assembly. The support frame 2 provides a stable support for the installation of the seat assembly or the car seat assembly.

[0050] The carrier 2 includes a carrier body 24, with carrier connection portions 21 disposed on opposite sides of the carrier body 24. The carrier body 24 is pivotally connected to the support arm 13, and the carrier 2 is positioned within the clearance space. The carrier body 24 is recessed downward to form a carrier clearance space for a seat pocket assembly or vehicle seat assembly. The seat pocket assembly or vehicle seat assembly is connected to corresponding carrier connection portions 21 on opposite sides of the seat pocket assembly or vehicle seat assembly, thereby improving the stability of the seat pocket assembly or vehicle seat assembly and allowing the seat pocket assembly or vehicle seat assembly to be positioned within the carrier clearance space, thereby reducing the installation height of the seat pocket assembly or vehicle seat assembly.

[0051] The overall shape of the carrier body 24 is adapted to the overall shape of the support arm 13 to provide maximum carrier clearance. After the seat pocket assembly or car seat assembly is installed on the carrier 2, the seat pocket assembly or car seat assembly is placed in the carrier clearance space to achieve clearance and lower the installation position of the seat pocket assembly or car seat assembly.

[0052] In some embodiments, see Figure 1 and Figure 2 As shown, the support arm 13 comprises a main body 131 and a pair of connecting portions 132 disposed on opposite sides of the main body 131. The pair of connecting portions 132 are respectively connected to the first side frame 11 and the second side frame 12, thereby securing the support arm 13. The main body 131 extends entirely horizontally and is located at a lower height than the location where the connecting portions 132 meet the first side frame 11. The connecting portions 132 are generally curved, connecting between the first side frame 11 and the main body 131 to create a clearance space.

[0053] The carrier frame 2 is rotatably connected to the support arm 13. Specifically, the carrier frame body 24 is rotatably mounted on the main body portion 131 of the support arm 13 to drive the seat pocket assembly or the car seat assembly to change direction, so that the child placed in the stroller faces forward or backward to face the caregiver, making it convenient for the caregiver to check the child's status.

[0054] Optionally, a carrier turntable 22 is provided on the carrier body 24, and a body turntable 14 is provided on the body portion 131 of the support arm 13. The carrier turntable 22 and the body turntable 14 are connected via a rotating shaft 23, resulting in a simple connection structure. Since the body portion 131 of the support arm 13 and the carrier body 24 are both rod-shaped structures, the carrier turntable 22 is provided on the carrier body 24, and the body turntable 14 is provided on the body portion 131 of the support arm 13 to facilitate the connection between the carrier body 24 and the body portion 131 of the support arm 13 and to improve the stability of the connection between the two.

[0055] A pair of connecting portions 132 are symmetrically positioned on either side of the main body 131 and extend upward from the main body 131, giving the support arm 13 a U-shape. The support frame body 24 is rotatably mounted at the center of the main body 131. The support frame body 24 is provided with a support frame turntable 22. The main body 131 is also provided with a main body turntable 14 that rotates relative to the turntable 22. The turntable 22 is positioned at the center of the support frame body 24. A gap is provided between the support frame body 24 and the support arm 13 to provide space for the support frame body 24 to rotate.

[0056] like Figure 2 As shown, the frame also has a rotational locking structure and an unlocking structure. The rotational locking structure includes a locking member and a locking slot that cooperates with the locking member. The locking member is provided on one of the main body portion 131 and the carrier body 24, and the locking slot is provided on the other. The rotational locking structure and unlocking structure are not shown in the figure. The frame also has a push handle assembly 4 rotatably mounted on the carrier 2. The push handle assembly 4 rotates between a use position and a non-use position. In the use position, the rotational locking structure is in a locked state, the carrier body 24 and the main body portion 131 cannot rotate relative to each other, and the seat bag assembly or car seat assembly cannot change direction. In the non-use position, the rotational locking structure is in an unlocked state, the carrier body 24 and the main body portion 131 can rotate relative to each other, and the seat bag assembly or car seat assembly can rotate and change direction.

[0057] The unlocking structure is coupled to the handle assembly 4 and the locking member, respectively, so that when the handle assembly 4 is rotated from the use position to the non-use position, the handle assembly 4, through the unlocking structure, drives the locking member to move away from the lock slot, thereby unlocking the rotary locking structure. When the handle assembly 4 is rotated from the non-use position to the use position, the locking member is disposed within the lock slot, locking the rotary locking structure. The unlocking structure can be a traction rope connected to the locking member and the handle assembly 4. When the handle assembly 4 is rotated from the use position to the non-use position, the traction rope can drive the locking member to move away from the lock slot.

[0058] The handle assembly 4 is pivotally connected to the support frame 2. The seat pocket assembly or car seat assembly can be placed between the handle assembly 4 and the support frame 2, lowering the seat pocket assembly or car seat assembly to increase the space between the handle assembly 4 and the handle assembly, thereby making it easier for the caregiver to push the stroller. The handle assembly 4 can be rotated to a non-use position, unlocking the support frame 2 and allowing the support frame 2 to rotate. When the handle assembly 4 is rotated to the use position, the support frame 2 cannot rotate, thereby locking the seat pocket assembly or car seat assembly in the correct orientation and preventing it from shaking.

[0059] Figures 3 to 7 The figure shows a schematic diagram of the process of unlocking the carrier 2 and rotating the carrier 2 to change the direction of the seat pocket assembly or the car seat assembly. The push handle assembly 4 is facing backward and is set at an angle to the vertical direction so that the push handle assembly 4 is in the use position. At this time, the position of the push handle assembly 4 is convenient for the caregiver to push the child stroller. When it is necessary to unlock the carrier 2, the push handle assembly 4 is rotated forward so that the push handle assembly 4 is in the non-use position, so that the push handle assembly 4 is parallel to the vertical direction. The carrier 2 is unlocked, and the push handle assembly 4 is held and applied to the carrier 2 to rotate the carrier 2 180°, thereby adjusting the direction of the seat pocket assembly or the car seat assembly. The push handle assembly 4 is then rotated toward the rear so that the push handle assembly 4 is set at an angle to the vertical direction so that the push handle assembly 4 is in the use position. While locking the carrier 2, the push handle assembly 4 is placed in a state that is convenient for the caregiver to push the child stroller.

[0060] The specific structure of the unlocking structure of the rotating push handle assembly 4 to unlock the carrier 2 or lock the carrier 2 is a prior art and will not be described in detail here. In some embodiments, the push handle assembly 4 is a U-shaped structure, and the two ends of the push handle assembly 4 are respectively connected to the two ends of the carrier 2. Figure 8 and Figure 9 As shown, the push handle assembly 4 includes an upper push handle 41 and a lower push handle 42. The lower push handle 42 includes two lower push rods, which are rotatably connected to the carrier frame 2. The upper push handle 41 is a U-shaped structure. The two ends of the upper push handle 41 are sleeved and connected to the two lower push rods. The two ends of the upper push handle 41 can be retracted in the corresponding lower push rods, thereby realizing the retractability of the push handle assembly 4, which is convenient for folding and storing the child stroller. Figure 8 is a structural diagram of the push handle assembly 4 in an expanded state, Figure 9 It is a structural schematic diagram of the push handle assembly 4 in a retracted state.

[0061] Reference Figure 2 As shown, the handle assembly 4 is provided with an upper handle unlocking button 43. Pressing the upper handle unlocking button 43 unlocks the upper handle 41 and the lower handle 42, allowing the upper handle 41 to extend and retract relative to the lower handle 42. When the upper handle unlocking button 43 is not pressed, the relative position of the upper handle 41 and the lower handle 42 is locked. The upper handle unlocking button 43 can be located on the top inner side of the upper handle 41, which is both aesthetically pleasing and convenient for user operation. The connection structure between the upper handle unlocking button 43 and the upper handle 41 and the lower handle 42 is conventional and will not be described in detail here.

[0062] The handle assembly 4 is also provided with a lower handle unlocking member 44. Operating this member rotates the handle assembly 4 relative to the carrier 2, thereby unlocking the carrier 2. When this member is not operated, the handle assembly 4 is fixed relative to the carrier 2, preventing the handle assembly 4 from shaking when the user pushes the stroller. The lower handle unlocking member 44 can be positioned outside the lower handle 42 for easier operation. The connection between the lower handle unlocking member 44, the lower handle 42, and the carrier 2 is conventional and will not be described in detail here.

[0063] See also Figure 1 As shown, the first side frame 11 and the second side frame 12 respectively include a front frame 111 and a rear frame 112, which are rotatably connected. The stroller frame 100 also includes a frame locking structure for locking the front and rear frames 111, 112 in relative rotation, and a frame unlocking structure for unlocking the frame locking structure. The frame unlocking structure includes a handle 5 rotatably mounted on the support arm 13. The handle 5 is rotated between a first position and a second position. In the first position, the frame locking structure is locked, and in the second position, the frame locking structure is unlocked. Specifically, the handle 5 unlocks the frame locking structure via the frame unlocking structure. Rotating the handle 5 allows the front and rear frames 111, 112 to be folded, facilitating storage of the stroller frame 100 and reducing its size after folding. When the front and rear frames 111, 112 are unfolded, their pivoting connection points are locked, preventing them from folding while the stroller is being pushed. Rotating the handle 5 to the second position can unlock the lock at the rotation connection point of the front bracket 111 and the rear bracket 112. Specifically, the specific structures of the above-mentioned bracket unlocking structure and bracket locking structure are existing technologies and will not be described in detail here.

[0064] Each front bracket 111 is provided with a front wheel 15 , and each rear bracket 112 is provided with a rear wheel 16 . A support arm 13 is connected between the two front brackets 111 .

[0065] Figures 10 to 13 The figure shows the folding process of the frame 100. When folding the frame 100, the handle assembly 4 is first reduced to its minimum size, then rotated backward until it fits against the rear bracket 112. The handle 5 is then rotated to unlock the front bracket 111 and the rear bracket 112. The front bracket 111 and the rear bracket 112 rotate toward each other, thus completing the folding of the frame 100.

[0066] like Figure 14 The figure shows a structural diagram of the seat pocket assembly 200, which includes a seat pocket seat plate unit 202 and a seat pocket backrest unit 203.
