[0025] Example 1

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model proposes a baby carrier capable of automatically unfolding and folding a sunshade, comprising: a basket frame 1, a sunshade frame 3, a motor 5 and a gear set 6; a sleeping basket 101 or a baby seat is arranged at the lower part of the basket frame 1, and hinged seats 2 are arranged on both sides of the basket frame 1; rotating joints 4 are respectively connected to the two ends of the sunshade frame 3, each rotating joint 4 is respectively rotatably connected to a hinged seat 2, and a folding sunshade cloth is connected between the sunshade frame 3 and the basket frame 1; the motor 5 is arranged on the hinged seat 2, and the motor 5 is directly or indirectly connected to the rotating joint 4, which can drive the rotating joint 4 and the sunshade frame 3 to swing, so that the folding sunshade cloth is unfolded and folded; the gear set 6 is rotatably arranged on one side of the hinged seat 2, the active end of the gear set 6 is connected to the output shaft of the motor 5, and the driven end of the gear set 6 is connected to the rotating joint 4.

[0027] The basket frame 1 is detachably connected to the frame of the baby carriage through the connecting parts on both sides. The basket frame 1 or the frame of the baby carriage is provided with a power supply and a switch 14, and the switch 14 can be used to control the forward and reverse rotation of the motor 5. The active end of the gear set 6 is a driving gear, and the driven end is a driven gear. The driving gear meshes with the driven gear. The driving gear is connected to the output shaft of the motor 5, and the driven gear is connected to the rotating joint 4, so that the motor 5 can drive the rotating joint 4 to swing through the driving gear and the driven gear. The inner and outer sides of the articulated seat 2 are also provided with an articulated inner shell 12 and an articulated outer shell 11, which are used to shield and protect the motor 5, the rotating joint 4 and the gear set 6.

[0028] When the baby carriage is outdoors, sunlight inevitably shines on the head of the baby in the sleeping basket 101 or the baby seat. The baby will have difficulty sleeping and may even cry after the baby's eyes are directly hit by the sunlight. The caregiver can operate the controller 9 to control the motor 5 to rotate, drive the awning frame 3 to swing, and unfold the folded sunshade cloth to block the sunlight, thereby ensuring the baby's sleep and stability.

[0029] Example 2

[0030] refer to Figure 3 On the basis of Example 1, a rotating seat 7 is rotatably provided on the articulated seat 2, one end of the rotating seat 7 is connected to the driven end of the gear set 6, and a manual rotating positioning structure is provided between the rotating seat 7 and the rotating joint 4.

[0031] A bearing 13 is arranged between the rotating seat 7 and the articulated seat 2, and the rotating seat 7 is connected to the driven gear. When there is no electricity or no need for electricity, the rotating seat 7 is fixed relative to the articulated seat 2, and the caregiver can directly rotate the awning frame 3 and the rotating joint 4 by hand. At this time, the manual rotating positioning structure between the rotating joint 4 and the rotating seat 7 will rotate and make the rotating joint 4 stay at the turning angle.

[0032] Example 3

[0033] refer to Figure 3 On the basis of Example 2, the manual rotation positioning structure includes a first lateral gear ring 701 and a second lateral gear ring 401. The first lateral gear ring 701 is arranged on the outer side of the rotating seat 7, and correspondingly, the second lateral gear ring 401 is arranged on the inner side of the rotating joint 4, and the second lateral gear ring 401 is meshed with the first lateral gear ring 701.

[0034] Both the first lateral gear ring 701 and the second lateral gear ring 401 are arc-shaped teeth. When the awning frame 3 and the rotating joint 4 are moved, the two ends of the awning frame 3 are deformed outward, and the first lateral gear ring 701 slides and rotates relative to the second lateral gear ring 401; when the awning frame 3 and the rotating joint 4 are stopped, the two ends of the awning frame 3 shrink to the original width, and the first lateral gear ring 701 on the inner side of the rotating joint 4 stays and gets stuck at the current second lateral gear ring 401, thereby realizing the rotation angle positioning.

[0035] Example 4

[0036] refer to Figure 2 , Figure 3 and Figure 4 On the basis of Example 1, a limit point 402 is set on the edge of the rotating joint 4, and an angle limit switch 8 is set on the outer side of the articulated seat 2, and the angle limit switch 8 corresponds to the limit point 402.

[0037] There are two limit points 402, corresponding to the rotating joint 4 turning to 180° and 90° positions respectively. After detecting the two limit points 402 through the angle limit switch 8, the motor 5 is powered off to make the awning frame 3 and the rotating joint 4 stay at the 180° or 90° position, among which the 180° position is the angle of the awning frame 3 when the foldable sunshade cloth is fully retracted, and the 90° position is the angle of the awning frame 3 when the foldable sunshade cloth is fully unfolded.

[0038] Example 5

[0039] refer to Figure 2 , Figure 3 and Figure 4 On the basis of Example 4, the angle limit switch 8 is a moiré switch, and a magnet is provided on the limit point 402 .

[0040] Each articulated seat 2 is respectively provided with a mole switch at the 180° position and the 90° position for detection. When the mole switch at the 180° position on the articulated seat 2 detects the magnet on the limit point 402, the mole switch responds and sends a signal. After receiving the signal, the controller 9 controls the motor 5 to stop moving, indicating that the awning frame 3 stops at the fully retracted position; when the two mole switches at the 180° and 90° positions on the articulated seat 2 respectively detect the magnets on the two limit points 402, the two mole switches respond and send a signal. After receiving the signal, the controller 9 controls the motor 5 to stop moving, indicating that the awning frame 3 stops at the fully unfolded position.

[0041] Example 6

[0042] refer to Figure 2 and Figure 3 , based on Example 1, the motor 5 is a worm gear reduction motor.

[0043] The motor 5 can be a worm gear reduction motor, which has a small size and a large torque and can be horizontally arranged on the hinge seat 2.

[0044] Example 7

[0045] Based on the first embodiment, the motor 5 is a stepping motor.

[0046] The motor 5 may also be a stepper motor, which has a short body, large torque, high angle control accuracy, and can be longitudinally arranged on the articulated seat 2.

[0047] Example 8

[0048] refer to Figure 4 On the basis of any of the above implementations, it also includes a controller 9 and an ultraviolet sensor 10, which are arranged on the frame of the baby carriage or on the basket frame 1, a signal receiving end of the controller 9 is connected to the signal of the ultraviolet sensor 10, another signal receiving end of the controller 9 is connected to the signal of the angle limit switch 8, and the signal output end of the controller 9 is connected to the signal of the motor 5.

[0049] After the basket frame 1 is mounted on the baby carriage frame, when the baby carriage is outdoors, sunlight shines on the ultraviolet sensor 10, and after the controller 9 receives the signal from the ultraviolet sensor 10, the controller 9 controls the motor 5 to rotate, driving the rotating joint 4 and the sunshade frame 3 to swing toward the middle position of the basket frame 1, driving the folding sunshade cloth to unfold, covering the head of the baby in the sleeping basket 101 or the baby seat, and preventing the baby's eyes from being directly exposed to sunlight. The caregiver can also operate the controller 9 to control the motor 5 to rotate, driving the sunshade frame 3 to unfold or fold.

[0050] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims. The components and structures not described in detail in this embodiment are well-known components and common structures or common means in the industry, and are not described here one by one.
