Description

Technical Field

[0001] The present application relates to the field of baby carriages, and particularly to a seat turning mechanism for a baby carriage. Background Art

[0002] With the development of economic technology, people pay more and more attention to the baby care technology. Baby strollers have become one of the essential tools for taking care of babies. The common structure of baby strollers mainly consists of a frame, a push rod, and a seat pocket, etc. To facilitate parents to take care of the baby, sometimes it is necessary to swap the installation position of the seat pocket on the baby stroller back and forth. Some baby strollers design the seat pocket and the seat pocket base as a detachable connection method. When turning, the seat pocket needs to be removed, reinstalled after changing the direction. The installation operation is relatively complex and easily wakes up the sleeping baby. There are also some baby strollers that use mechanical operations, or rotate the push rod 180° to achieve turning. They are relatively single in function, complex in structure, inconvenient in operation, and cannot meet the needs of modern daily life. Summary of the Invention

When the seat assembly is in the reverse use state, the second locking pin cooperates with the locking hole for locking. A linkage mechanism is provided between the push rod assembly and the seat assembly. When the push rod assembly rotates, it can control the locking or unlocking of the seat locking mechanism through the linkage mechanism.

[0005] Preferably, a set of first locking pins and second locking pins are respectively provided on the left and right sides of the seat assembly, and there is a height difference between each set of first locking pins and second locking pins. A locking hole is respectively provided on the left and right sides of the base assembly, and there is a height difference between the locking holes on both sides. The locking hole on the right side of the base assembly is at the same height and corresponds to the first locking pin on the right side of the seat assembly and the second locking pin on the left side of the seat assembly. The locking hole on the left side of the base assembly is at the same height and corresponds to the first locking pin on the left side of the seat assembly and the second locking pin on the right side of the seat assembly.

[0006] When the push rod assembly is in a vertical or forward flipped state, the first locking pin and the second locking pin are in an unlocked position or have no corresponding locking holes. At this time, the seat assembly and the base assembly cannot be locked and are in an unlocked state.

[0007] Preferably, the base assembly is rotatably connected to the seat assembly via an upper seat body at its upper end, the locking holes are formed on the left and right sides of the upper seat body, and the front and rear parts of the left and right sides of the upper seat body are respectively formed with guide surfaces for the first locking pin and the second locking pin to slide into when the seat assembly rotates.

[0010] When the push rod assembly is flipped, the track groove of the push rod assembly drives the swivel linkage to slide by sliding cooperation with the first boss, and its second boss drives the swivel adjustment part to rotate relative to the seat assembly, and adjusts the first locking pin and the second locking pin to a locked position or an unlocked position through the first traction lock and the second traction rope.

[0011] Preferably, the push rod assembly and the seat assembly are rotatably connected via a first connecting shaft, the swivel pocket adjusting member has an axial hole in the middle portion that rotatably cooperates with the first connecting shaft, and the seat pocket linkage member has a guide groove in the middle portion that can slidably cooperate with the first connecting shaft; the socket of the swivel pocket adjusting member is located on one side of the axial hole.

[0012] Preferably, the seat assembly comprises a seat frame and a backrest frame, the seat assembly is rotatably connected to the base assembly via the seat frame, and the first locking pin and the second locking pin are slidably disposed on the seat frame. The push rod assembly is coaxially rotatably connected to the seat frame and the backrest frame or is rotatably connected to the seat frame alone.

[0013] Preferably, the base assembly is a foldable lower frame, and a front wheel assembly and a rear wheel assembly are provided on the front and rear sides thereof respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, the seat assembly is rotatably arranged horizontally on the base assembly. Therefore, the seat assembly can be rotated as needed and locked in the forward use state or the reverse use state by the seat locking mechanism, enabling the flexible change of the occupant's orientation without changing the orientation of the main vehicle body and the caregiver. The structure is simple and easy to use.

[0016] 2. The push rod assembly of the present invention is rotatably arranged on the seat assembly, and a linkage mechanism is provided between the two.

[0017] 3. The seat locking mechanism in the present invention is ingeniously designed. A set of first locking pins and second locking pins with a height difference are respectively arranged on the left and right sides of the seat assembly. The locking holes on the right side of the base assembly are at the same height and corresponding to the first locking pins on the right side of the seat assembly and the second locking pins on the left side of the seat assembly. The locking holes on the left side of the base assembly are at the same height and corresponding to the first locking pins on the left side of the seat assembly and the second locking pins on the right side of the seat assembly. Therefore, when the seat assembly is in different use states, only one of the first locking pins and the second locking pins is in the position corresponding to the locking hole and is locked and matched, while the other has no corresponding locking hole; this design can prevent the seat assembly from being accidentally locked during the rotation process and ensure the reliability of the commutation operation.

These are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] As Figures 1 to 19 shown, a seat turning mechanism of a baby stroller includes a push rod assembly 1, a seat assembly 2, and a base assembly 3. The push rod assembly 1 is provided on the seat assembly 2 and can rotate forward and backward relative to the seat assembly 2. The seat assembly 2 is provided on the base assembly 3 and can rotate around a vertical axis relative to the base assembly 3. A seat locking mechanism 4 is provided between the seat assembly 2 and the base assembly 3 to limit the rotation of the seat assembly 2 relative to the base assembly 3. The seat locking mechanism 4 can lock the seat assembly 2 when it is in the forward use state and the reverse use state respectively. A linkage mechanism 5 is provided between the push rod assembly 1 and the seat assembly 2. When the push rod assembly 1 rotates, it can control whether the seat locking mechanism 4 is locked through the linkage mechanism 5.

[0046] In this embodiment, the seat locking mechanism 4 includes a first locking pin 401 and a second locking pin 402 that are slidably engaged with the seat assembly 2. A first return member 403 is provided between the first locking pin 401 and the seat assembly 2, and a second return member 404 is provided between the second locking pin 402 and the seat assembly 2. Locking holes 405 corresponding to the first locking pin 401 and the second locking pin 402 are provided on the base assembly 3.

[0047] Preferably, a set of the first locking pin 401 and the second locking pin 402 are respectively provided on the left and right sides of the seat assembly 2, and there is a height difference between each set of the first locking pin 401 and the second locking pin 402. In the drawings of this embodiment, the first locking pin 401a and the second locking pin 402a on the right side are arranged in a staggered manner with one being higher and the other being lower, and the first locking pin 401b and the second locking pin 402b on the left side are arranged in a staggered manner with one being lower and the other being higher. One locking hole 405b and 405a are respectively provided on the left and right sides of the base assembly 3, and there is a height difference between the two locking holes 405b and 405a. In the drawings of this embodiment, the position of the locking hole 405a on the right side of the base assembly 3 is higher than the position of the locking hole 405b on the left side of the base assembly 3. Among them, the locking hole 405a on the right side of the base assembly 3 has the same height and corresponds to the first locking pin 401a on the right side of the seat assembly 2 and the second locking pin 402b on the left side of the seat assembly 2. The locking hole 405b on the left side of the base assembly 3 has the same height and corresponds to the first locking pin 401b on the left side of the seat assembly 2 and the second locking pin 402a on the right side of the seat assembly 2.

[0048] When the seat assembly 2 is in the forward use state, the first locking pin 401a cooperates with the locking hole 405a for locking, and the first locking pin 401b cooperates with the locking hole 405b for locking;

[0049] When the seat assembly 2 is in the reverse use state, the second locking pin 402a cooperates with the locking hole 405b for locking, and the second locking pin 402b cooperates with the locking hole 405a for locking;

[0050] When the push rod assembly 1 is in the vertical or forward-flipped state, the first locking pin 401 and the second locking pin 402 are in the unlocked position or there is no corresponding locking hole 405. At this time, the seat assembly 2 and the base assembly 3 cannot be locked and are in the unlocked state.

[0051] The above seat locking mechanism 4 is ingeniously designed. When the seat assembly 2 is in different use states, only one of the first locking pin 401 and the second locking pin 402 is in the position corresponding to the locking hole 405 and is locked and cooperated, while the other has no corresponding locking hole 405. This design can prevent the seat assembly 2 from being accidentally locked during rotation and ensure the reliability of the commutation operation.

[0052] Preferably, the base assembly 3 is rotatably connected to the seat assembly 2 through the upper seat body 301 at its upper end. The above locking holes 405 are formed on the left and right sides of the upper seat body 301, and guiding surfaces 403 for the first locking pin 401 and the second locking pin 402 to slide into are respectively formed at the front and rear parts on the left and right sides of the upper seat body 301. The setting of the guiding surface 406 facilitates the first locking pin 401 and the second locking pin 402 to smoothly slide into the side surface of the upper seat body 301 when the seat assembly 2 rotates, ensuring flexibility during rotation.

[0053] In this embodiment, the linkage mechanism 5 includes a seat pocket linkage member 501 and a pocket rotation adjusting member 502. The pocket rotation adjusting member 502 is rotatably connected to the seat assembly 2, the seat pocket linkage member 501 is slidably connected to the seat assembly 2. The seat pocket linkage member 501 is provided with a first convex column 5011 and a second convex column 5012. Its first convex column 5011 is slidably engaged with the track groove 101 on the push rod assembly 1, and its second convex column 5012 is movably engaged with the insertion hole 5021 of the pocket rotation adjusting member 502. This movable engagement is preferably a rotational and sliding engagement, that is, the second convex column 5012 rotates relative to the insertion hole 5021 while also having a little sliding. The two sides of the pocket rotation adjusting member 502 are respectively connected to the corresponding first locking pin 401 and second locking pin 402 through a first traction cable 503 and a second traction cable 504.

[0054] When the push rod assembly 1 is turned over, the track groove 101 of the push rod assembly 1 drives the sling linkage 501 to slide through the sliding fit with the first convex column 5011, and the second convex column 5012 thereof drives the sling adjusting member 502 to rotate relative to the seat assembly 2, and adjusts the first locking pin 401 and the second locking pin 402 to be in the locked position or the unlocked position through the first traction lock 503 and the second traction cable 504.

[0055] Wherein, the push rod assembly 1 and the seat assembly 2 are rotationally connected through a first connecting shaft 102. The middle part of the sling adjusting member 502 has a shaft hole 5022 that is rotationally matched with the first connecting shaft 102, and the middle part of the seat sling linkage 501 has a guiding groove 5013 that can be slidably matched with the first connecting shaft 102; the jack 5021 of the sling adjusting member 502 is located on one side of the shaft hole 5022.

[0056] In the present invention, by rotating the push rod assembly 1, the locking or unlocking of the seat locking mechanism 4 is controlled by using the linkage mechanism 5, so that the unlocking operation is very convenient and easy to operate.

[0057] In this embodiment, the seat assembly 2 is preferably a foldable and collapsible seat structure, which at least includes a seat frame 201 and a backrest frame 202. Usually, the backrest frame 202 can be adjusted in the use angle relative to the seat frame 201. Since this seat structure is a conventional technology in the art, it is not limited and described in detail herein.

[0058] In this embodiment, the seat assembly 2 is rotationally connected to the base assembly 3 through the seat frame 201, and the first locking pin 401 and the second locking pin 402 are slidably arranged on the seat frame 201. The push rod assembly 1 can be coaxially connected to the seat frame 201 and the backrest frame 202, or can be separately rotationally connected to the seat frame 201.

[0059] In this embodiment, the base assembly 3 is preferably a foldable and collapsible lower frame body, and a front wheel assembly 302 and a rear wheel assembly 303 are respectively arranged on the front and rear sides thereof. Since the lower frame body is a conventional technology in the art and has various structural types, it is not limited and described in detail herein.

[0060] The working principle of the present invention is:

[0061] As Figure 1 and Figure 2 shown, when the seat assembly 2 is in the forward use state (facing forward), the first locking pin 401 cooperates with the locking hole 405 to lock, realizing the locking between the seat assembly 2 and the base assembly 3; however, at this time, there is no corresponding locking hole 405 for the second locking pin 402, so the second locking pin 402 is not in the locked position.

[0062] As Figure 3 and Figure 4As shown in the figure, when the direction needs to be reversed (from forward to backward), rotate the push rod assembly 1 forward. When the push rod assembly 1 is in the vertical or forward-flipped state, the track groove 101 of the push rod assembly 1 drives the turntable linkage 501 to slide through the sliding fit with the first convex post 5011. The second convex post 5012 of the turntable linkage 501 drives the turntable adjusting member 502 to rotate relative to the seat assembly 2, and drives the first locking pin 401 to enter the unlocking position through the first traction lock 503. However, at this time, the second locking pin 402 is still in a state where there is no corresponding locking hole 405 and is still not in the locking position. Therefore, at this time, the seat assembly 2 and the base assembly 3 are in the unlocked state, and the seat assembly 2 can rotate relative to the base assembly 3.

[0063] As Figures 5 to 10 As shown in the figure, after using the push rod assembly 1 to drive the seat assembly 2 to rotate 180° together, when the seat assembly 2 is in the reverse use state (facing backward), rotate the push rod assembly 3 backward to reset it. At this time, the second locking pin 402 cooperates with the locking hole 405 to lock, realizing the locking between the seat assembly 2 and the base assembly 3. However, at this time, the first locking pin 401 has no corresponding locking hole 405. Therefore, the first locking pin 401 is not in the locking position.

[0064] When the direction needs to be reversed again (from backward to forward), similarly rotate the push rod assembly 1 forward. When the push rod assembly 1 is in the vertical or forward-flipped state, drive the turntable adjusting member 502 to rotate through the sliding of the turntable linkage 501, and drive the second locking pin 402 to enter the unlocking position through the second traction lock 504. However, at this time, the first locking pin 401 is still in a state where there is no corresponding locking hole 405 and is still not in the locking position. Therefore, at this time, the seat assembly 2 and the base assembly 3 are in the unlocked state, and the seat assembly 2 can rotate relative to the base assembly 3.

[0065] When the seat assembly 2 rotates to the forward use state (facing forward), rotate the push rod assembly 1 backward to reset it, and the first locking pin 401 cooperates with the locking hole 405 again to lock, realizing the locking between the seat assembly 2 and the base assembly 3.

[0066] The present invention can rotate the seat assembly 2 as needed and use the seat locking mechanism 4 to lock the seat assembly 2 in the forward use state or the reverse use state, which can flexibly change the orientation of the rider and will not change the orientation of the main vehicle body and the caregiver. The structure is simple and easy to use.
