[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The rotating frame of the present invention can rotate relative to the bottom support frame, and the handle is detachably connected to the rotating frame, so when the rotating frame is in the vertical support position, the baby carriage can be used as a scooter. At this time, the child can hold the handle, then step on the bottom support frame with one foot, and slide on the ground with the other foot. When the rotating frame rotates backward to the horizontal bearing position, the handle is separated from the rotating frame and snapped into the connection position on the bottom support frame. At this time, the baby carriage can be used as a slide. The child can hold the handle and ride on the rotating frame, and can slide by pushing the ground with both feet. Therefore, the baby carriage of the present invention can be used as both a scooter and a slide, and has multiple functions. Moreover, an arc groove is provided on the bottom support frame along the circumferential direction, and a support member that can slide in the arc groove is provided on the rotating frame. Since the support member can be supported against the end of the arc groove after sliding in the arc groove, when the rotating frame is in the transverse bearing position, the strength of the connection position between the rotating frame and the bottom support frame can be enhanced. Even if the rear side of the rotating frame in the transverse bearing position is suspended in the air, when a child rides on the rotating frame, the connection between the rotating frame and the bottom support frame can be ensured to be firm, thereby avoiding the connection position between the rotating frame and the bottom support frame from breaking, thereby ensuring that the baby carriage has sufficient bearing capacity. In addition, the sliding member and the handle share a connection position. When the rotating frame is in the vertical support position, the sliding member locks the rotating frame and the bottom support frame, and when the rotating frame is in the transverse bearing position, the handle is engaged in the connection position, so the handle can also prevent the rotating frame from rotating in the opposite direction, so the handle can also play a role in locking the rotating frame and the bottom support frame, making the entire baby carriage simple in structure, with fewer parts and low cost.

[0017] 2. When the rotating frame of the baby carriage of the present invention is in the vertical support position, the first transverse axis abuts against the first starting end and the second transverse axis abuts against the second starting end. When the rotating frame is in the transverse bearing position, the first transverse axis abuts against the first terminal end and the second transverse axis abuts against the second terminal end. Therefore, when the rotating frame stays in the transverse bearing position where sufficient bearing force is required, the first transverse axis abuts against the first terminal end and the second transverse axis abuts against the second terminal end. The first terminal end and the second terminal end can provide sufficient supporting force to prevent the rotating frame from rotating further backward, and can ensure that the rotating frame will not break at the connection position with the bottom support frame due to the child riding, thereby ensuring the structural strength of the baby carriage and ensuring safety.

[0018] 3. The first arc groove of the present invention is located in front of the first axis, and the second arc groove is located in the rear of the first axis. This symmetrical design can ensure that when the rotating frame is in the lateral load position, the connection position between the bottom support frame and the rotating frame has sufficient structural strength to prevent the rotating frame from breaking after the child rides on it, thereby ensuring safety.

[0019] 4. The present invention has a simple structure, is easy to operate, has low cost, and has multiple functions, and is suitable for popularization and application.

[0037] The present invention will be further described below in conjunction with the accompanying drawings:

[0038] like Figures 1 to 11 As shown, a baby carriage comprises a bottom support frame 1, on which a wheel assembly 2 is arranged, on which a rotating frame 3 which can rotate relative to the bottom support frame 1 about a first axis A is connected, on which a handle 4 is detachably connected, and the positions where the rotating frame 3 can stay include a vertical support position and a lateral bearing position for a child to sit after rotating relative to the bottom support frame 1, when the rotating frame 3 stays in the vertical support position, the handle 4 is connected to the upper end of the rotating frame 3, and when the rotating frame 3 stays in the lateral bearing position, the handle 4 and the rotating frame 3 are The bottom support frame 1 is separated and engaged with the connection position 5 on the bottom support frame 1, and the bottom support frame 1 is provided with an arc groove 61 along the circumferential direction, and the rotating frame 3 is provided with a support member 62 that penetrates the arc groove 61 and can slide in the arc groove 61 and abut against the end of the arc groove 61 when the rotating frame 3 rotates. The rotating frame 3 is also connected with a sliding member 7 that can slide relative to it. When the rotating frame 3 is in the vertical support position, the connection position 5 is engaged with the sliding member 7, and when the rotating frame 3 is in the horizontal bearing position, the connection position 5 is separated from the sliding member 7 and is engaged with the handle 4. Of course, the arc groove 61 and the support member 62 can also be interchanged, that is, the arc groove 61 is set on the rotating frame 3, and the support member 62 is set on the bottom support frame 1, which is an equivalent structure.

[0039] like Figures 1 to 11 As shown, the rotating frame 3 can rotate relative to the bottom support frame 1, and the handle 4 is detachably connected to the rotating frame 3, so when the rotating frame 3 is in the vertical support position, as shown in FIG. Figure 1 As shown, the baby carriage is used as a scooter. At this time, the child can hold the handle 4, then step one foot on the bottom support frame 1, and slide on the ground with the other foot. When the rotating frame 3 rotates backward to the lateral bearing position, the handle is separated from the rotating frame and is engaged in the connection position on the bottom support frame, as shown in FIG. Figure 2As shown, the baby carriage can be used as a scooter. The child can hold the handle 4 and ride on the rotating frame 3, and can slide by pushing the ground with both feet. Therefore, the baby carriage of the present invention can be used as both a scooter and a scooter, and has multiple functions. In addition, an arc groove 61 is provided on the bottom support frame 1 along the circumferential direction, and a support member 62 that can slide in the arc groove 61 is provided on the rotating frame 3. Since the support member 62 can be abutted against the end of the arc groove 61 after sliding in the arc groove 61, when the rotating frame 3 is in the lateral bearing position, the strength of the connection position between the rotating frame 3 and the bottom support frame 1 can be enhanced. Even if the rear side of the rotating frame 3 in the lateral bearing position is suspended in the air, when the child rides on the rotating frame 3, it can ensure that the rotating frame 3 is firmly connected to the bottom support frame 1, avoid the connection position between the rotating frame 3 and the bottom support frame 1 from breaking, and ensure that the baby carriage has sufficient bearing capacity. In addition, the sliding member 7 and the handle 4 share the connecting position 5. When the rotating frame 3 is in the vertical supporting position, the sliding member 7 locks the rotating frame 3 and the bottom supporting frame 1. When the rotating frame 3 is in the horizontal bearing position, the handle 4 is engaged in the connecting position 5. Therefore, the handle 5 can also prevent the rotating frame 3 from rotating in the opposite direction. Therefore, the handle 4 can also play the role of locking the rotating frame 3 and the bottom supporting frame 1, so that the entire baby carriage has a simple structure, fewer parts and components, and low cost.

[0040] like Figure 3 and Fig.10 As shown, the arc groove 61 includes a first arc groove 611 and a second arc groove 612 which are symmetrical to each other, and the abutting member 62 includes a first transverse axis 621 which penetrates the first arc groove 611 and a second transverse axis 622 which penetrates the second arc groove 612. Therefore, the rotating frame 3 and the bottom support frame 1 can abut against each other at multiple points, which can improve the connection strength between the rotating frame 3 and the bottom support frame 1 when the rotating frame 3 is in the lateral bearing position, and ensure that the baby carriage has sufficient bearing capacity.

[0041] like Figure 4 , Figure 6 , Figure 8 , Fig.10As shown, the first arc groove 611 has a first starting end 611a and a first ending end 611b, and the second arc groove 612 has a second ending end 612b close to the first starting end 611a and a second starting end 612a close to the first ending end 611b. When the rotating frame 3 is in the vertical supporting position, the first transverse axis 621 abuts against the first starting end 611a and the second transverse axis 622 abuts against the second starting end 612a. When the rotating frame 3 is in the horizontal bearing position, the first transverse axis 621 abuts against the first ending end 611b and the second transverse axis 622 abuts against the second ending end 612b. Therefore, when the rotating frame 3 stays at the lateral bearing position where sufficient bearing force is required, the first transverse axis 621 abuts against the first terminal end 611b and the second transverse axis 622 abuts against the second terminal end 612b, and the first terminal end 611b and the second terminal end 612b can provide sufficient supporting force to prevent the rotating frame 3 from rotating further backward, and can ensure that the rotating frame 3 will not break at the connection position with the bottom support frame 1 due to the child sitting on it, thereby ensuring the structural strength of the baby carriage and ensuring safety.

[0042] like Figure 4 As shown, a metal sheet 15 is fixed on the bottom support frame 1, and the rotating frame 3 is connected to the metal sheet 15 by rotating around the first axis A. When the rotating frame 3 is in the vertical support position, the first transverse axis 621 and the second transverse axis 622 are respectively against the two sides of the metal sheet 15, and when the rotating frame 3 is in the horizontal bearing position, the first transverse axis 621 and the second transverse axis 622 are also respectively against the two sides of the metal sheet 15. Therefore, the first transverse axis 621 and the second transverse axis 622 not only abut against the ends of the corresponding first arc groove 611 and the second arc groove 612, but also abut against the two sides of the metal sheet 15, so that the metal sheet 15 also provides support force for the rotating frame 3, ensuring that the rotating frame 3 is firmly connected to the bottom support frame 1 and has sufficient bearing capacity.

[0043] like Figure 4 As shown, the connection position 5 is a connection hole vertically arranged on the bottom support frame 1, and the central axis B of the connection hole intersects with the first axis A in the same vertical plane, which can make the structure of the baby carriage simple, compact and stable.

[0044] like Figure 4 As shown, the first arc groove 611 is located at the front side of the first axis A, and the second arc groove 612 is located at the rear side of the first axis A. This symmetrical design can ensure that when the rotating frame 3 is in the lateral bearing position, the connection position between the bottom support frame 1 and the rotating frame 2 has sufficient structural strength to prevent the rotating frame from breaking after the child rides on it, thereby ensuring safety.

[0045] like Figure 6 , Figure 8 and Fig.11As shown, the sliding member 7 includes a sliding pin 71 that can slide along the central axis B and engage with the connecting hole. The rotating frame 3 is provided with an exposed operating block 72 that can push the sliding pin 71 to slide. A first reset spring 73 is also provided between the sliding pin 71 and the rotating frame 3. When the rotating frame 3 needs to be switched from the vertical support position to the horizontal bearing position, the sliding pin 71 can be withdrawn from the connecting position 5 by simply pulling the operating block 72 upwards. The operation is very convenient and quick. When the rotating frame 3 is rotated to the horizontal bearing position, the handle 4 is detached from the rotating frame 3 and engaged with the connecting position 5 to complete the switch from the scooter to the sliding vehicle.

[0046] like Figure 4 and Figure 8 As shown, the bottom support frame 1 is also provided with an insertion groove 8 for inserting the end of the sliding pin 71 when the bottom support frame 1 is in the transverse bearing position. The insertion groove 8 has an upper opening 81 for the sliding pin 71 to slide out from the insertion groove 8 when the rotating frame 3 rotates from the transverse bearing position to the vertical supporting position. The insertion groove 8 also has a blocking wall 82 that can block the lower side wall of the sliding pin 71 when the rotating frame 3 is in the transverse bearing position. The blocking wall 82 can block the lower side wall of the sliding pin 71, which can further prevent the rotating frame 3 from rotating backward, ensuring the stability of the rotating frame 3 when it is in the transverse bearing position. When the rotating frame 3 needs to move from the transverse bearing position to the vertical supporting position, it is only necessary to pull out the handle 4 from the connecting position 5, then rotate the rotating frame 3 forward, and finally connect the handle 4 to the upper end of the rotating frame 3 again. In this process, the sliding pin 71 slides out from the upper opening 81 and is inserted into the connecting position 5 again.

[0047] like Figure 1 , Figure 2 , Fig.17 As shown, the bottom support frame 1 includes a vehicle base 11 and a movable seat 12 rotatably connected to the vehicle base 11 around a second axis C, the rotating frame 3 is rotatably connected to the movable seat 12 around a first axis A, the connecting position 5 and the arc groove 61 are arranged on the movable seat 12, and a locking structure for locking the movable seat 12 and the vehicle base 11 is also provided between the movable seat 12 and the vehicle base 11, the locking structure includes a locking hole 91 arranged on the vehicle base 11, a locking pin 92 is provided in the movable seat 12, which can slide therein and can be engaged or disengaged with the locking hole 91, the locking pin 92 is provided with an operating portion 93 exposed to the movable seat 12, and a second reset spring 94 is also provided between the locking pin 92 and the movable seat 12. Therefore, when the rotating frame 3 is in the vertical support position and the locking pin 92 is disengaged from the locking hole 91, the handle 4, the rotating frame 3 and the movable seat 12 can be rotated together around the second axis C to be close to the vehicle base 11, so that the baby carriage can be folded for easy carrying or storage.

[0048] like Figure 1 , Figure 2 , Figures 14 to 16 As shown, the wheel assembly 2 includes a left front wheel 21 and a right front wheel 22 arranged on the front side of the bottom support frame 1, a rear wheel 23 is arranged on the rear side of the bottom support frame 1, and a left connecting seat 24 and a right connecting seat 25 that can rotate relative to the bottom support frame 1 are arranged on the front side of the bottom support frame 1. The included angles of the projection line D of the rotation axis of the left connecting seat 24 and the right connecting seat 25 in the vertical plane and the horizontal plane are both acute angles, the left front wheel 21 and the right front wheel 22 are correspondingly rotationally connected to the left connecting seat 24 and the right connecting seat 25, and a transmission rod 26 hinged to the left connecting seat 24 and the right connecting seat 25 is also arranged between the left connecting seat 24 and the right connecting seat 25, a fixed seat 13 is arranged on the bottom support frame 1 and corresponds to the middle position of the transmission rod 26, a left return spring 27 is arranged between the fixed seat 13 and the left connecting seat 24, and a right return spring 28 is arranged between the fixed seat 13 and the right connecting seat 25. Since the projection line D of the rotation axis of the left connecting seat 24 and the right connecting seat 25 in the vertical plane and the included angle of the horizontal plane are both acute angles, when the child holds the handle 4 and needs to turn, he only needs to apply downward pressure to one side to achieve the turning. If he needs to turn to the left, he presses down the left side of the handle 4, and if he needs to turn to the right, he presses down the right side of the handle 4. In addition, a transmission rod 26 is also arranged between the left connecting seat 24 and the right connecting seat 25. When the left connecting seat 24 or the right connecting seat 25 rotates to one side to adjust the direction, the transmission rod 26 pushes the right connecting seat 25 or the left connecting seat 24 to rotate accordingly, so as to achieve the purpose of synchronous action of the left connecting seat 24 and the right connecting seat 25, and ensure flexible turning. In addition, the fixed seat 13 on the bottom support frame 1 is located in the middle position of the transmission rod 26, and a left return spring 27 is arranged between the fixed seat 13 and the left connecting seat 24, and a right return spring 28 is arranged between the right connecting seat 25, so that the wheel assembly 2 can be automatically returned to the center after the baby carriage turns.

[0049] like Figure 1 , Fig. 9 , Fig.12 and Fig.13As shown, the handle 4 is detachably connected to the rotating frame 3 and can be extended and retracted in the rotating frame 3. The rotating frame 3 is provided with a plurality of slots 31. The handle 4 is provided with a latch 41 that can be engaged with or disengaged from the slots 31. The handle 4 is also provided with an operating member 42 that can drive the latch 41 to disengage from the slots 31 when pressed. The rotating frame 3 is also provided with a two-way lock structure, which includes a sliding button 01 that can slide along the rotating frame 3. The sliding button 01 is provided with a blocking block 02 that can block the handle 4 from extending and retracting in the rotating frame 3 and can make way for the handle 4 to extend and retract after following the sliding button 01. A third reset spring 03 is provided between the blocking block 02 and the rotating frame 3. The height of the handle 4 can be adjusted by cooperating with the plurality of slots 31 and the latch 41. When adjustment is required, the action of the latch 41 can be controlled by pressing the operating member 42. The operating member 41 can adopt the operating structure in a traditional baby carriage, which will not be described in detail here. What is important is that a double lock structure is provided on the rotating frame 3. When the height of the handle 4 needs to be adjusted or the handle 4 needs to be taken out, the sliding button 01 must be pushed first. The sliding button 01 drives the blocking block 02 to move, so that the blocking block 02 makes way for the handle 4 so that the handle 4 can move. This can effectively prevent the operating part 42 from malfunctioning and causing the handle 4 to move relative to the rotating frame 3, thereby ensuring safety.

[0050] like Figure 2 The bottom support frame 1 is also rotatably connected with a footrest 14 that can be unfolded to both sides. When the rotating frame 3 is in the horizontal bearing position for children to sit on, the footrest 14 can be rotated out of the bottom support frame 1 for children to step on, and when the footrest 14 is not needed, the footrest 14 can be rotated into the bottom support frame 1 and folded.
