[0001] This disclosure claims priority to Chinese patent application number 2023118684103, filed on December 31, 2024, entitled “A Reversible Child Stroller” and priority to Chinese patent application number 2023118664453, filed on December 31, 2023, entitled “A Reversible Child Stroller”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the field of children's products, and in particular to a reversible children's stroller. Background Art

[0003] Strollers are an important means of transportation for children. To accommodate a variety of usage scenarios, strollers are typically reversible, meaning they can be used in a forward-facing position with the child facing away from the parent and a rear-facing position with the child facing the parent. However, existing reversible strollers primarily utilize two methods for reversing: the first involves removing the seat assembly and then reversing the seat assembly; the second involves rotating the push rod from the rear to the front and then reversing the entire stroller. Both reversing methods are relatively cumbersome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a reversible baby stroller with a novel structure.

[0072] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0073] In the description of the present invention, the directions involved, such as “front”, “rear”, “left”, “right”, “up” and “down”, are all defined with reference to the directions observed by the user when pushing the cart, that is, as shown in FIG2 , the left direction in the figure is “front”, the right direction in the figure is “rear”, the upper direction in the figure is “up”, the lower direction in the figure is “down”, and the directions perpendicular to the viewing angle in the figure are “left” and “right”.

[0074] The present invention discloses a reversible baby stroller, as shown in FIG1-13, comprising: a support frame, an operating member, a seat assembly 2 and a linkage assembly.

[0075] The operating member is rotatably connected to the support frame around a first axis A; the support frame is a vehicle frame, and the operating member is rotatably mounted on the vehicle frame.

[0076] The seat assembly 2 is rotatably connected to the support frame around the second axis B. The seat assembly 2 has a bearing space; the bearing space is used for children to sit.

[0077] The linkage assembly is arranged between the operating member and the seat assembly 2 to link the operating member and the seat assembly 2. The convertible child stroller has a forward use state and a rearward use state. In the forward use state, the carrying space of the seat assembly 2 is set forward, and in the rearward use state, the carrying space of the seat assembly 2 is set rearward; during the rotation of the operating member around the first axis A, the linkage assembly drives the seat assembly 2 to rotate around the second axis B, thereby allowing the convertible child stroller to switch between the forward use state and the rearward use state.

[0078] The present invention realizes the control of the rotation of the seat assembly 2 by setting the operating member, which is convenient for users.

[0079] In a specific embodiment, the reversible stroller further comprises a push rod 1 mounted on the support frame. The push rod 1 is rotatably mounted on the support frame along a first axis A and serves as an operating member. In this embodiment, the operating member is a push handle 1, which is used to control the rotation of the seat assembly, making operation more convenient. It is understood that in other embodiments, a separate component may be provided as the operating member to control the seat assembly.

[0080] When the seat assembly 2 is in the forward-facing state, the load-bearing space of the seat assembly 2 is arranged away from the push rod 1. When the seat assembly 2 is in the rearward-facing state, the load-bearing space of the seat assembly 2 is arranged toward the push rod 1. The push rod 1 is relatively arranged at the rear side of the seat assembly 2. When the seat assembly 2 is in the forward-facing state, the load-bearing space of the seat assembly 2 is open toward the front, that is, away from the push rod 1. When the seat assembly 2 is in the rearward-facing state, the load-bearing space of the seat assembly 2 is open toward the rear, that is, toward the push rod 1.

[0081] The push rod 1 includes a push rod body 11 , which is extended along the direction of the first axis A. The push rod body 11 drives the linkage assembly when rotating around its own circumferential direction.

[0082] As shown in Figures 1-6, in the first embodiment, the push rod 1 is a straight rod extending along the first axis A. The use of a straight rod is likely to interfere with the seat assembly during the rotation of the seat assembly 2. Even if no interference occurs, when the child is sitting rearward, the presence of the push rod 1 is likely to interfere with the child's legs or feet.

[0083] In order to avoid the above-mentioned problem, in another embodiment, as shown in Figures 9-13, when in the rearward use state, part of the push rod 1 is bent in the direction away from the seat assembly 2 to form a clearance space 8 opening toward the seat assembly 2, and the clearance space 8 can be used to accommodate the feet or legs of children.

[0084] In a specific embodiment, as shown in Figures 9-13, the push rod 1 includes a push rod body 11 and a push rod extension 16 provided on the push rod body 11, and the push rod extension 16 is rotatably mounted on the support frame along the direction of the first axis A;

[0085] As shown in FIG. 11-12 , the push rod body 11 is disposed at one end of the push rod extension portion 16 away from the push rod extension portion 16 , and a clearance space 8 is formed between the push rod extension portion 16 and the push rod body 11 .

[0086] In this embodiment, the push rod 1 includes two parts: a push rod body 11 and a push rod extension 16. The push rod body 11 and the push rod extension 16 extend in directions intersecting with each other to form a bent structure. In other embodiments, the push rod 1 can also be integrally bent, with part of the push rod 1 being bent in a curve.

[0087] A push rod handle 12 is provided at one end of the push rod body 11 away from the push rod extension 16. The push rod 1 is driven to rotate by the push rod handle 12, and the push rod handle 12 is located on an extension of the first axis A. The location of the push rod handle 12 on the extension of the first axis A enables the height of the push rod handle 12 to remain substantially unchanged when the push rod 1 rotates around the first axis A.

[0088] As shown in FIG11 , in the rearward-facing state, the push rod body 11 is disposed on a side away from the seat assembly 2 relative to the first axis A;

[0089] As shown in FIG. 9 , in the forward use state, the push rod body 11 is arranged on the side facing the seat assembly 2 relative to the first axis A, and the push rod body 11 is relatively arranged between the first axis A and the seat assembly 2 .

[0090] As shown in Figures 9-11, the extension direction of the push rod body 11 is arranged to intersect with the extension direction of the first axis A. When the push rod 1 rotates around the first axis A, the movement trajectory of the push rod body 11 is a cone as a whole.

[0091] As shown in Figures 1, 3 and 7, the linkage assembly includes a first rotating member 5 rotatably mounted on the support frame along a first axis A, a second rotating member 6 rotatably mounted on the support frame along a second axis B, and a transmission structure linking the first rotating member 5 and the second rotating member 6;

[0092] The push rod 1 is arranged on the first rotating member 5, and the seat assembly 2 is arranged on the second rotating member 6. The push rod 1 rotates synchronously with the first rotating member 5, and the seat assembly 2 rotates synchronously with the second rotating member 6.

[0093] The second axis B extends vertically in the up-down direction, and the first axis A extends obliquely upward from front to back.

[0094] In one embodiment, as shown in Figures 1 and 3, the first rotating member 5 and the second rotating member 6 are both rotating disks. The transmission structure includes a plurality of first gears 51 arranged along the circumference of the first rotating member 5 and a plurality of second gears 61 arranged along the circumference of the second rotating member 6. The plurality of first gears 51 and the plurality of second gears 61 are directly or indirectly engaged with each other. In this embodiment, the first rotating member 5 and the second rotating member 6 are actually two intermeshing gear disks.

[0095] In another embodiment, as shown in Figure 7, the transmission structure further includes a first traction rope 14 and a second traction rope 15. The first traction rope 14 has a first traction rope first end 141 and a first traction rope second end 142 arranged in the length direction thereof, and the second traction rope 15 has a second traction rope first end 151 and a second traction rope second end 152 arranged in the length direction thereof. The first traction rope first end 141 is fixedly connected to the first rotating member 5, the first traction rope second end 142 is fixedly connected to the second rotating member 6, the second traction rope first end 151 is fixedly connected to the first rotating member 5, and the second traction rope second end 152 is fixedly connected to the second rotating member 6. The first traction rope 14 and the second traction rope 15 are always tensioned and wound around the first rotating member 5 and the second rotating member 6.

[0096] The following describes several specific embodiments as examples: Example 1

[0097] 1 to 6 , the reversible stroller of the present invention includes a support frame, a push rod 1, a seat assembly 2, a linkage assembly, a front wheel assembly 3, and a rear wheel assembly 4. The support frame includes a front bracket 9 extending obliquely upward from front to rear, a rear bracket 10 extending obliquely upward from rear to front, and a carrier 7. The front wheel assembly 3 is disposed below the front bracket 9, and the rear wheel assembly 4 is disposed below the rear bracket 10. In this embodiment, the rear bracket 10 includes a left rear bracket disposed on the left side and a right rear bracket disposed on the right side. The front bracket 9 is disposed between the left and right rear brackets. The carrier 7 is disposed at the upper end of the front bracket 9. Specifically, the carrier 7 is fixedly or rotatably disposed at the upper end of the front bracket 9. In this embodiment, to facilitate folding and storage, the carrier 7, the front bracket 9, and the rear bracket 10 are rotatably connected about the same axis. The front bracket 9 is pivotally connected to the left and right rear brackets. Of course, in other embodiments, the carrier 7 can also be movably disposed at the upper end of the front bracket 9. In other embodiments, other forms of support frames may also be provided, for example, the front bracket 9 includes a left front bracket provided on the left side and a right front bracket provided on the right side, the rear bracket 10 is provided between the left front bracket and the right front bracket, and the supporting frame 7 is provided at the upper end of the rear bracket 10.

[0098] In this embodiment, the operating member is a push rod 1. In other embodiments, the operating member may also be a knob or operating lever. Specifically, in this embodiment, the push rod 1 includes a push rod body 11 extending obliquely upward from front to back, and a push rod handle 12 disposed at the upper end of the push rod body 11. In this embodiment, the push rod body 11 is a rectangular rod, specifically comprising an upper push rod and a lower push rod. The upper push rod and the lower push rod are slidably and telescopically connected to facilitate storage of the push rod 1. The push rod handle 12 is quasi-circular, which is convenient for gripping and rotating operation. The push rod body 11 is rotatably connected to the support frame 7 about a first axis A, and the seat assembly 2 is rotatably connected to the support frame 7 about a second axis B. As shown in FIG3 , the first axis A extends obliquely upward from front to back, and the second axis B extends vertically in the vertical direction. The first axis A and the second axis B intersect at an oblique angle. Of course, in other embodiments, the first axis A and the second axis B may also intersect perpendicularly. The first axis A passes through the push rod body 11.

[0099] The linkage assembly is used to link the push rod 1 and the seat assembly 2, thereby causing the seat assembly 2 to rotate about a second axis B when the push rod 1 rotates about a first axis A. In this embodiment, the linkage assembly includes a first gear and a second gear meshing with the first gear. The first gear is disposed at the lower end of the push rod body 11 and is rotatably connected to the support frame 7 along with the push rod 1 along the first axis A. The second gear is disposed below the seat assembly 2 and is rotatably connected to the support frame 7 along the second axis B along with the seat assembly 2. Specifically, in this embodiment, the first gear is fixed to the lower end of the push rod body 11, and the second gear is fixed to the lower end of the seat assembly 2. In this embodiment, the radius of the first gear is equal to the radius of the second gear. This arrangement ensures that when the push rod body 11 rotates 180° about the first axis, the seat assembly 2 also rotates 180° about the second axis. Of course, in other embodiments, the radius of the first gear can be larger or smaller than the radius of the second gear. When the radius of the first gear is set larger than the radius of the first gear, a smaller rotation of the push rod body 11 can drive a larger rotation of the seat assembly 2.

[0100] In other embodiments, the first gear and the second gear may be arranged not to be directly engaged with each other, that is, other transmission components may be provided between the first gear and the second gear.

[0101] The carrier 7 has a hollow cavity, within which the first and second gears are disposed. The support frame further includes a cover 8 disposed above the carrier 7 to cover the first and second gears. The cover 8 includes a first mating surface 83 extending horizontally in the front-to-back direction and a second mating surface 84 extending obliquely downward from the front to the back. The rear of the first mating surface 83 connects to the front of the second mating surface 84. A first mating hole 81 is defined in the first mating surface 83, and a second mating hole 82 is defined in the second mating surface 84. As shown in FIG1 , a first gear connecting portion 52 is further defined above the first gear, and a second gear connecting portion 62 is further defined above the second gear. The first gear connecting portion 52 passes through the first mating hole 81 and connects to the lower end of the push rod body 11, while the second gear connecting portion 62 passes through the second mating hole 82 and connects to the lower portion of the seat assembly 2. Due to the cavity and cover 8 , the first and second gears are not exposed, reducing the risk of pinching during use and enhancing the overall appearance of the reversible stroller.

[0102] As shown in FIG. 1 , the support frame in this embodiment further includes a rotating shaft 101 . The rotating shaft 101 has a first axis A. The rotating shaft 101 is disposed on the supporting frame 7 and passes through the first gear and the push rod body 11 .

[0103] The reversible stroller of the present invention has a forward use state and a rearward use state, as shown in Figures 2 and 4. When in the forward use state, the parent's pushing direction is consistent with the child's facing direction, and the child faces away from the parent, as shown in Figure 6. When in the rearward use state, the parent's pushing direction is opposite to the child's facing direction, and the child faces the parent. When switching from the forward use state to the rearward use state, as shown in Figure 5, the parent holds the push rod handle 12 and rotates it counterclockwise. Of course, in other embodiments, it can also be rotated clockwise, so that the push rod body 11 rotates around the first axis A, and the push rod body 11 drives the first gear to rotate synchronously around the first axis A. The first gear drives the second gear to rotate around the second axis B. Driven by the second gear, the seat assembly 2 rotates synchronously around the second axis B. When the seat assembly 2 rotates 180° around the second axis B, the conversion from the forward use state to the rearward use state is completed. When switching from the rearward use state to the forward use state, it can be completed by simply holding the push rod handle 12 and rotating it clockwise. No further details are given here.

[0104] The reversible stroller of the present invention has an unfolded state and a folded state, as shown in FIG13 . When the reversible stroller of the present invention is folded, it is necessary to adjust the reversible stroller to a forward use state, and the upper push rod and the lower push rod slide and retract relative to each other. The front bracket 9, the rear bracket 10, and the supporting frame 7 rotate and retract relative to each other, and the supporting frame 7 drives the seat assembly 2 and the push rod 1 to rotate and retract synchronously. As shown in FIG5 , when in the folded state, the seat assembly 2 is retracted to the outermost side of the reversible stroller, and the push rod 1 is located between the seat assembly 2 and the front bracket 9. Example 2

[0105] As shown in Figures 7-8, the main difference between this embodiment and embodiment 1 lies in the difference in the linkage components. In this embodiment, the linkage components are a first rotating member 5, a second rotating member 6, a first traction rope 13 and a second traction rope 14. The first rotating member 5 and the push rod 1 are connected to the support frame for rotation around the first axis A, and the second rotating member 6 and the seat assembly 2 are connected to the support frame for rotation around the second axis B. The first end 131 of the first traction rope is fixedly connected to the first rotating member 5, the second end 132 of the first traction rope is fixedly connected to the second rotating member 6, and the second traction rope is fixedly connected to the second rotating member 6. One end 141 is fixedly connected to the first rotating member 5, and the second end 142 of the second traction rope is fixedly connected to the second rotating member 6. The first traction rope 13 and the second traction rope 14 are always tensioned and wound around the first rotating member 5 and the second rotating member 6. Therefore, by rotating the push rod 1, the first rotating member 5 is driven to rotate around the first axis A. Driven by the first traction rope 13 and the second traction rope 14, the second rotating member 6 also rotates around the second axis B, driving the seat assembly 2 to rotate around the second axis B, thereby realizing the conversion between the forward use state and the rearward use state.

[0106] Specifically in this embodiment, the first end 131 of the first traction cable and the first end 141 of the second traction cable are arranged adjacent to each other, and the second end 132 of the first traction cable and the second end 142 of the first traction cable are arranged adjacent to each other. When the first end 131 and the second end 141 of the first traction cable are located on the left side of the convertible child stroller, the second end 132 and the second end 142 of the first traction cable are located on the right side of the convertible child stroller. Conversely, when the first end 131 and the second end 141 of the first traction cable are located on the right side of the child stroller, the second end 132 and the second end 142 of the first traction cable are located on the left side of the convertible child stroller. When the push rod 1 rotates around the first axis A in the first direction, the seat assembly 2 is driven to move around the second axis B in the first direction. In this embodiment, the circumferences of the first rotating member 5 and the second rotating member 6 are equal. That is, when the push rod 1 rotates around the first axis A in the first direction by an angle, the seat assembly 2 is driven to rotate around the second axis B in the first direction by the same angle. Of course, in other embodiments, other winding methods can also be selected for the first traction rope 13 and the second traction rope 14, such as the first end 131 of the first traction rope and the first end 141 of the second traction rope are respectively arranged on both sides of the center of the first rotating member 5, and the line connecting them passes through the center of the first rotating member 5, and the second end 132 of the first traction rope and the second end 142 of the second traction rope are respectively arranged on both sides of the center of the second rotating member 6, and the line connecting them passes through the center of the second rotating member 6. When the push rod 1 rotates in a first direction around the first axis A, it drives the seat assembly 2 to move in a second direction around the second axis B, and the first direction is opposite to the second direction. Example 3

[0107] As shown in Figures 9-12, the push rod 1 includes a push rod body 11 extending upward and obliquely from front to back, a push rod handle 12 provided at the upper end of the push rod body 11, and a push rod extension 16 provided at the lower end of the push rod body 11. The push rod extension 16 extends downward and obliquely from front to back. In this embodiment, the push rod body 11 is in the shape of a rectangular rod, specifically including an upper push rod and a lower push rod. The upper push rod and the lower push rod are slidably and telescopically connected to each other for easy storage of the push rod 1. The push rod handle 12 is in a circular shape for easy grasping and rotation operation. The push rod extension 16 is rotatably connected to the carrier 7 around the first axis A. The push rod extension 16 rotates around the first axis The line rotates to form a rotating surface (not shown in the figure), which is perpendicular to the first axis A. The first axis A intersects with the push rod handle 12 at a first point C, and the first axis intersects with the rotating surface at a second point (not shown in the figure). If the push rod handle 12 is operated to make the push rod extension 16 rotate 360° around the first axis A, the rotating surface and the motion trajectory of the push rod body 11 form a cone, and the line segment with the first point C and the second point as the end points is the height of the cone. In this way, when the push rod handle 12 is operated to make the push rod extension 16 rotate around the first axis A, the push rod handle is always at the same height, making the operation more convenient for parents.

[0108] The seat assembly 2 is rotatably connected to the carrier frame 7 around the second axis B. As shown in Figure 3, the first axis A extends obliquely upward from front to rear, and the second axis B extends vertically in the up-down direction. The first axis A and the second axis B intersect at an angle. Of course, in other embodiments, the first axis A and the second axis B can also intersect vertically.

[0109] The linkage assembly is used to link the push rod 1 and the seat assembly 2, so that the seat assembly 2 rotates around the second axis B during the rotation of the push rod 1 around the first axis A. In this embodiment, the linkage assembly includes a first rotating member 5, a second rotating member 6, a first traction rope 13 and a second traction rope 14. The first rotating member 5 is arranged at the lower end of the push rod extension 16, and it and the push rod extension 16 are rotated together around the first axis A and the carrier 7. The second rotating member 6 is arranged below the seat assembly 2, and it and the seat assembly 2 are rotated together around the second axis B and the carrier 7. The first traction rope 13 has a The first traction rope has a first end 131 and a second end 132 of the first traction rope in its length direction, and the second traction rope 14 has a second traction rope first end 141 and a second traction rope second end 142 arranged in its length direction. The first traction rope first end 131 is fixedly connected to the first rotating member 5, and the first traction rope second end 132 is fixedly connected to the second rotating member 6. The second traction rope first end 141 is fixedly connected to the first rotating member 5, and the second traction rope second end 142 is fixedly connected to the second rotating member 6. The first traction rope 13 and the second traction rope 14 are always tensioned and wound around the first rotating member 5 and the second rotating member 6. As shown in Figures 6-7, specifically in this embodiment, the first end 131 of the first traction cable and the first end 141 of the second traction cable are arranged adjacent to each other, and the second end 132 of the first traction cable and the second end 142 of the second traction cable are arranged adjacent to each other. When the first end 131 and the second end 141 of the first traction cable are located on the left side of the reversible child stroller, the second end 132 and the second end 142 of the first traction cable are located on the right side of the reversible child stroller. Conversely, when the first end 131 and the second end 141 of the first traction cable are located on the right side of the reversible child stroller, the second end 132 and the second end 142 of the first traction cable are located on the left side of the reversible child stroller. When the push rod 1 rotates about the first axis A in the first direction, the seat assembly 2 is driven to move about the second axis B in the first direction. In this embodiment, the circumferences of the first rotating member 5 and the second rotating member 6 are equal. That is, when the push rod 1 rotates about the first axis A in the first direction by an angle, the seat assembly 2 is driven to rotate about the second axis B in the first direction by the same angle. Of course, in other embodiments, other winding methods can also be selected for the first traction rope 13 and the second traction rope 14, such as the first end 131 of the first traction rope and the first end 141 of the second traction rope are respectively arranged on both sides of the center of the first rotating member 5, and the line connecting them passes through the center of the first rotating member 5, and the second end 132 of the first traction rope and the second end 142 of the second traction rope are respectively arranged on both sides of the center of the second rotating member 6, and the line connecting them passes through the center of the second rotating member 6. When the push rod 1 rotates in a first direction around the first axis A, it drives the seat assembly 2 to move in a second direction around the second axis B, and the first direction is opposite to the second direction.

[0110] In this embodiment, as shown in Figure 12, the carrier 7 includes a base portion 71 and an extension portion 72 extending downward and backward from the base portion 71. The first rotating member 5 is arranged inside the base portion 71, and the second rotating member 6 is arranged inside the extension portion 72. The base portion 71 is arranged below the seat assembly 2 to provide support for the seat assembly 2, and the base portion 71 is rotatably connected to the seat assembly 2 around the second axis B. The middle portion of the extension portion 72 is fixedly connected to the front bracket 9, and the lower end portion of the extension portion 72 is rotatably connected to the push rod extension portion 16 around the first axis A.

[0111] The reversible stroller of the present invention has a forward use state and a rearward use state. As shown in Figures 9-10, when in the forward use state, the parent's pushing direction is consistent with the child's facing direction, and the child faces away from the parent. At this time, the push rod 1 is close to the seat assembly 2, and the push rod body 11 is located above the first axis A. As shown in Figures 11-12, when in the rearward use state, the parent's pushing direction is opposite to the child's facing direction, and the child faces the parent. At this time, a space 8 for accommodating the child's feet or legs is formed between the push rod 1 and the seat assembly 2, and the push rod body 11 is located below the first axis A. When switching from the forward use state to the rearward use state, the parent holds the push rod handle 12 in reverse. The push rod extension 16 rotates clockwise, and of course it can also rotate clockwise in other embodiments, so that the push rod extension 16 rotates around the first axis A, and the push rod extension 16 drives the first rotating member 5 to rotate synchronously around the first axis A. The first rotating member 5 drives the second rotating member 6 to rotate around the second axis B through the first traction rope 13 and the second traction rope 14. Driven by the second rotating member 6, the seat assembly 2 rotates synchronously around the second axis B. When the seat assembly 2 rotates 180° around the second axis B, the conversion from the forward use state to the rearward use state is completed. When converting from the rearward use state to the forward use state, it can be completed as long as the parent holds the push rod handle 12 and rotates it clockwise. I will not go into details here.

[0112] The reversible stroller of the present invention has an unfolded state and a folded state. When the reversible stroller of the present invention is folded, the reversible stroller needs to be adjusted to a forward use state, the upper push rod and the lower push rod slide and retract relative to each other, the front bracket 9, the rear bracket 10, and the supporting frame 7 rotate and retract relative to each other, and the supporting frame 7 drives the seat assembly 2 and the push rod 1 to rotate and retract synchronously. As shown in Figure 5, when in the folded state, the seat assembly 2 is retracted to the outermost side of the reversible stroller, and the push rod 1 is located between the seat assembly 2 and the front bracket 9. Example 4

[0113] The main difference between this embodiment and Example 3 lies in the difference in the linkage assembly. In this embodiment, the first rotating member 5 of the linkage assembly is a first gear, and the second rotating member 6 is a second gear. The first gear and the push rod 1 are jointly rotatably connected to the support frame around the first axis A, and the second gear and the seat assembly 2 are jointly rotatably connected to the support frame around the second axis B. Specifically in this embodiment, the first gear and the push rod extension 16 are jointly rotatably connected to the support frame 7 around the first axis A, and the second gear and the seat assembly 2 are jointly rotatably connected to the support frame 7 around the second axis B. The first gear and the second gear can be directly engaged through gears, or other transmission components can be provided. Therefore, by rotating the push rod 1, the first gear is driven to rotate around the first axis A, and the second gear is also driven by the first gear to rotate around the second axis B, driving the seat assembly 2 to rotate around the second axis B, thereby realizing the conversion between the forward use state and the rearward use state.

[0114] As shown in Figures 9-12, the present invention also discloses a reversible stroller, comprising: a support frame, a push rod 1 and a seat assembly 2, wherein the push rod 1 is arranged on the support frame; the seat assembly is arranged on the support frame and has a bearing space;

[0115] The reversible stroller has a forward-facing state and a rearward-facing state. As shown in Figures 9-10 , in the forward-facing state, the carrying space of the seat assembly 2 is arranged away from the push rod 1. As shown in Figures 11-12 , in the rearward-facing state, the carrying space of the seat assembly 2 is arranged toward the push rod 1.

[0116] When in the rearward-facing state, a portion of the push rod 1 is bent away from the seat assembly 2 to form a clearance space 8 that opens toward the seat assembly 2 .

[0117] The push rod 1 is rotatably connected to the support frame around a first axis A;

[0118] In the forward use state, as shown in FIG. 9 , the push rod 1 is rotated until the opening of the clearance space 8 is facing away from the seat assembly 2 .

[0119] The seat assembly 2 is rotatably connected to the support frame around a second axis B. The reversible child stroller further includes a linkage assembly, which is arranged between the push handle 1 and the seat assembly. When the push rod 1 rotates, the push rod 1 links the seat assembly 2 and enables the reversible child stroller to be converted between the forward use state and the rearward use state.

[0120] The push rod 1 includes a push rod body 11 and a push rod extension 16 provided on the push rod body 11. The push rod extension 16 is rotatably mounted on the support frame along the direction of the first axis A.

[0121] The push rod body 11 is disposed at one end of the push rod extension portion away from the first axis A, and the clearance space 8 is formed between the push rod extension portion 16 and the push rod body 11 .

[0122] A push rod handle 12 is provided at one end of the push rod body 11 away from the push rod extension portion 16 , and the push rod handle 12 is located on an extension line of the first axis A.

[0123] The push rod handle 12 is rotated 180 degrees, and the reversible stroller is converted between a forward use state and a rearward use state.
