Description

Technical Field

[0001] This utility model relates to children's transportation tools, and in particular to a foldable bassinet and a stroller including the bassinet. Background Technology

[0002] Some strollers can accommodate both child seats and bassinets to accommodate younger infants, making them popular with consumers. However, most bassinets currently available for strollers can only be folded by compressing the top and bottom frames vertically; they cannot be folded in length. Furthermore, the soft fabric cover covering the bassinet must be removed, and the support between the top and bottom frames must be manually manipulated to release it, making the process extremely cumbersome. A few bassinets can be folded in length, but they use a two-stage folding method, resulting in a V-shape. Because the bassinet rods and folding joints themselves occupy space, the open angle of the end of the bassinet rod furthest from the folding joint after folding still occupies space, and forcibly pressing it down may damage the soft fabric cover at the joint. For example, in embodiment one of the invention patent applications (application number 2024112926283), although the bassinet can tilt to one side after folding to fit the frame for easier folding, the structure is complex and the manufacturing cost is high. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problem that although the existing bassinet can tilt to one side to fit the frame after being folded, the structure is complicated, and to provide a foldable bassinet and a stroller including the bassinet.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A foldable sleeping basket includes an upper frame, a lower frame, and a folding assembly. The upper frame includes a first upper frame, a second upper frame, and a first bending portion. The first upper frame and the second upper frame are connected via the first bending portion. The first upper frame and the second upper frame can be folded in opposite directions around their connection points with the first bending portion. The lower frame includes a first lower frame, a second lower frame, and a third lower frame. One end of the first lower frame and the third lower frame are rotatably connected, and the other end of the second lower frame and the third lower frame are rotatably connected. The first lower frame and the second lower frame can be folded in opposite directions around their connection points with the third lower frame. The folding assembly includes a first folding portion and a second folding portion. The first folding portion is disposed between the first upper frame and the second lower frame. Between the first and second upper and lower frame bodies, the second folding section is disposed between the second upper frame body and the second lower frame body. When the first and second upper frame bodies fold in opposite directions, the first and second folding sections drive the first and second lower frame bodies to fold in opposite directions as well. The first folding section includes a first connecting rod and a first support rod. One end of the first connecting rod is rotatably connected to the first upper frame body, and the other end of the first connecting rod is rotatably connected to the first lower frame body. One end of the first support rod is rotatably connected to the first upper frame body, and the other end of the first support rod is fixedly connected to the third lower frame body. The second folding section includes a second connecting rod. One end of the second connecting rod is rotatably connected to the second upper frame body, and the other end of the second connecting rod is rotatably connected to the second lower frame body.

[0006] In this design, the first and second upper frames are connected by a first bend, and each can fold upwards at its connection point with the first bend. Similarly, the first and second lower frames can fold in opposite directions at their connections with the third lower frame. Furthermore, a first folding section is provided between the first and first lower frames, and a second folding section is provided between the second and second lower frames. When the first upper frame folds upwards at its connection point with the first bend, the first folding section will cause the first lower frame to fold upwards at its connection point with the third lower frame. Likewise, when the second upper frame folds upwards, it will also cause the second lower frame to fold upwards, thus reducing the space occupied by the bassinet for storage. When it needs to be unfolded for use, moving the first and second upper frames will also unfold the first and second lower frames. Because a third lower frame is positioned between the first and second lower frames, the lower frame folds into three sections. The third lower frame provides space between the first and second lower frames when folded. Firstly, the folded U-shaped arrangement of the first, second, and third lower frames takes up less space compared to a two-section V-shaped frame, reducing the risk of damage to the canopy and fabric cover from compression and ensuring a flatter surface after folding. Secondly, the first support rod is fixedly connected to the third lower frame. In the folded state, the tilt angles of the first upper frame, second upper frame, first lower frame, and second lower frame are consistent with the first support rod, allowing the basket to tilt to one side to conform to the frame and facilitate folding. Furthermore, when the third lower frame is mounted on the stroller frame, the downward folding of the second upper frame exerts a force on the first bending section, causing it to move downwards. Since the rotation point of the first support rod and the first upper frame is fixed, the downward movement of the first bending section causes the other end of the first upper frame to fold upwards. Therefore, only one hand is needed to fold the second upper frame, which also folds the entire bassinet. The first folding section also features a first connecting rod, distributing the connection points with the upper and lower frames, resulting in even force distribution and a more stable and reliable structure less prone to deformation. This design is simple in structure, low in manufacturing cost, and less prone to malfunctions during use.

[0007] Preferably, the second folding section further includes a third link, one end of which is rotatably connected to the second upper frame, and the other end of which is rotatably connected to the second lower frame or the third lower frame.

[0008] In this design, the other end of the third link can be rotatably connected to the third lower frame. The connection positions of the second folding part with the upper and lower frames are dispersed, resulting in uniform stress distribution and a more stable and reliable structure that is less prone to deformation.

[0009] Preferably, the foldable basket also includes a locking mechanism for locking the first bend, preventing the first upper frame from folding down with the second upper frame and the first lower frame from folding down with the second lower frame.

[0010] In this design, when the bassinet is unfolded, the locking mechanism locks the first bending section, preventing the first and second upper frames from folding. Since the first and second lower frames are linked to the first and second upper frames via the first and second folding sections, the first and second lower frames also cannot fold when the first and second upper frames cannot be folded. Compared to relying on the tightness of the rotation points to maintain the bassinet's usability, this structure is safer and more stable.

[0011] Preferably, an unlocking mechanism is provided on the upper or lower frame, which can unlock the locking mechanism.

[0012] In this solution, an unlocking mechanism is installed on the upper or lower frame. Compared to manually unlocking the locking mechanisms on both sides, or even having to open the cover on the bassinet to operate the first and second folding sections, the operation is more convenient and simple.

[0013] A stroller that includes a foldable bassinet as described above.

[0014] In this design, the bassinet on the stroller has a first upper frame and a second upper frame connected by a first bend. Both frames can be folded upwards from their connection points with the first bend. Similarly, the first lower frame and the second lower frame can be folded in opposite directions from their connection points with the third lower frame. Furthermore, a first folding section is provided between the first upper frame and the first lower frame, and a second folding section is provided between the second upper frame and the second lower frame. When the first upper frame folds upwards from its connection point with the first bend, the first folding section will cause the first lower frame to fold upwards from its connection point with the third lower frame. Similarly, when the second upper frame folds upwards, it will also cause the second lower frame to fold upwards, thus reducing the bassinet's space requirements for storage. When the bassinet needs to be unfolded, moving the first and second upper frames will unfold the first and second lower frames. Because a third lower frame is positioned between the first and second lower frames, the lower frame folds into three sections. This third lower frame provides space between the first and second lower frames when folded. Firstly, the folded U-shaped arrangement of the first, second, and third lower frames occupies less space compared to a two-section V-shaped frame, reducing the risk of damage to the canopy and fabric cover from compression and ensuring a flatter surface after folding. Secondly, the first support rod is fixedly connected to the third lower frame. In the folded state, the tilt angles of the first, second, first, and second lower frames align with the first support, allowing the basket to tilt to one side for better fit against the frame and easier folding. The first folding section also features a first connecting rod, distributing the connection points with the upper and lower frames for even stress distribution. The structure is simple, low-cost, and more stable and reliable, less prone to deformation. Attached Figure Description

[0039] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0040] like Figures 1-4As shown, this utility model embodiment provides a foldable sleeping basket, including an upper frame 1, a lower frame 2, and a folding assembly. The upper frame 1 includes a first upper frame 11, a second upper frame 12, and a first bending portion 13. The first upper frame 11 and the second upper frame 12 are connected through the first bending portion 13. The first upper frame 11 and the second upper frame 12 can be folded in opposite directions with their connection points to the first bending portion 13 as rotation points. The lower frame 2 includes a first lower frame 21, a second lower frame 22, and a third lower frame 23. One end of the first lower frame 21 and the third lower frame 23 are rotatably connected. The second lower frame 22 and the third lower frame 23 are rotatably connected. The other end of the lower frame 23 is rotatably connected. The first lower frame 21 and the second lower frame 22 can be folded in opposite directions with their connection points to the third lower frame 23 as rotation points. The folding assembly includes a first folding part 31 and a second folding part 32. The first folding part 31 is disposed between the first upper frame 11 and the first lower frame 21, and the second folding part 32 is disposed between the second upper frame 12 and the second lower frame 22. When the first upper frame 11 and the second upper frame 12 are folded in opposite directions, the first folding part 31 and the second folding part 32 drive the first lower frame 21 and the second lower frame 22 to fold in opposite directions. The first folding section 31 includes a first connecting rod 311 and a first support rod 312. One end of the first support rod 312 is rotatably connected to the middle position of the first upper frame 11, and the other end of the first support rod 312 is fixedly connected to the third lower frame 23. One end of the first connecting rod 311 is rotatably connected to the first upper frame 11, and the other end of the first connecting rod 311 is rotatably connected to the first lower frame 21. The second folding section 32 includes a second connecting rod 321. One end of the second connecting rod 321 is rotatably connected to the middle position of the second upper frame 12, and the other end of the second connecting rod 321 is rotatably connected to the second lower frame 22.

[0041] In this embodiment, the first upper frame 11 and the second upper frame 12 are connected by a first bending portion 13, and can be folded upwards at the connection point with the first bending portion 13. Similarly, the first lower frame 21 and the second lower frame 22 can be folded in opposite directions at the connection point with the third lower frame 23. Furthermore, a first folding portion 31 is provided between the first upper frame 11 and the first lower frame 21, and a second folding portion 32 is provided between the second upper frame 12 and the second lower frame 22. When the first upper frame 11 folds upwards at the connection point with the first bending portion 13, the first folding portion 31 will cause the first lower frame 21 to fold upwards at the connection point with the third lower frame 23. Similarly, when the second upper frame 12 folds upwards, it will also cause the second lower frame 22 to fold upwards, thus reducing the space occupied by the bassinet for storage. When the device needs to be unfolded, moving the first upper frame 11 and the second upper frame 12 will also unfold the first lower frame 21 and the second lower frame 22. Since a third lower frame 23 is provided between the first lower frame 21 and the second lower frame 22, the lower frame 2 folds into a three-section configuration. Of course, in other embodiments, the third lower frame 23 may itself be two or more sections, resulting in a more natural transition at the bends. The third lower frame 23 provides space between the first lower frame 21 and the second lower frame 22 in the folded state. On one hand, after folding, the first lower frame 21, the second lower frame 22, and the third lower frame 23 are arranged in a parallel U-shape, which occupies less space compared to a two-section V-shaped frame; on the other hand, the awning and fabric cover are less likely to be damaged by compression, and the folded surface is flatter. Of course, in other embodiments, a third upper frame can also be provided between the first upper frame 11 and the second upper frame 12 to achieve a better folded effect. Furthermore, because the first support rod 312 is fixedly connected to the third lower frame 23, in the folded state, the tilt angles of the first upper frame 11, the second upper frame 12, the first lower frame 21, and the second lower frame 22 are consistent with the first support rod 312, allowing the basket to tilt to one side to fit the frame and facilitate folding of the entire vehicle. The first folding section 31 is also equipped with a first connecting rod 311, which distributes the connection points between the basket and the upper frame 1 and the lower frame 2, resulting in even stress distribution and a more stable and reliable structure that is less prone to deformation. This design is simple in structure, low in manufacturing cost, and less prone to malfunctions during use.

[0042] In a preferred embodiment, the second folding part 32 further includes a third connecting rod 322, one end of which is rotatably connected to the second upper frame 12, and the other end of which is rotatably connected to the connection between the second lower frame 22 and the third lower frame 23.

[0043] In this embodiment, the other end of the third link 322 is rotatably connected to the connection between the second lower frame 22 and the third lower frame 23. The connection positions of the second folding part 32 with the upper frame 1 and the lower frame 2 are dispersed, the force is evenly distributed, and the structure is more stable, reliable and less prone to deformation.

[0044] As a preferred embodiment, the foldable sleeping basket also includes a locking mechanism 4, which is used to lock the first bending part 13 so that the first upper frame 11 and the second upper frame 12, and the first lower frame 21 and the second lower frame 22 cannot be folded.

[0045] In this design, when the bassinet is unfolded, the locking mechanism 4 locks the first bending portion 13, preventing the first upper frame 11 and the second upper frame 12 from folding down. Since the first lower frame 21 and the second lower frame 22 are linked to the first upper frame 11 and the second upper frame 12 via the first folding portion 31 and the second folding portion 32, the first lower frame 21 and the second lower frame 22 cannot be folded down when the first upper frame 11 and the second upper frame 12 cannot be folded down. Compared to relying on the tightness of the rotation point itself to maintain the bassinet's usability, this structure is safer and more stable. Of course, in other embodiments, the locking mechanism 4 can also be provided on the third lower frame 23 to lock it, or it can be provided on both the first bending portion 13 and the third lower frame 23, both achieving the same effect.

[0046] As a preferred embodiment, the upper frame 1 is provided with an unlocking mechanism 5, which can unlock the locking mechanism 4.

[0047] In this design, an unlocking mechanism 5 is installed on the upper frame 1. The unlocking mechanism 5 releases the locking mechanism 4 from its locked state via a traction cable. Figure 7 As shown, the locking mechanism 4 can lock the first bent portion 13 using a locking pin or gear locking mechanism. Meanwhile, as... Figure 4 and Figure 6 When the first folding part 13 is in the folded state, the locking mechanism 4 can also lock it to keep the entire basket in the folded state. Since the locking mechanism 4 and unlocking mechanism 5 are diverse in this technical field, they will not be specifically described or limited here. Compared to manually unlocking the locking mechanisms 4 on both sides separately, or even needing to open the cover on the basket to operate the first folding part 31 and the second folding part 32, the operation is much more convenient and simple.

[0048] like Figures 5-6 As shown, this embodiment also provides a stroller, which includes the aforementioned foldable bassinet, and the third lower frame 23 is detachably mounted on the stroller frame.

[0049] In this embodiment, the bassinet on the stroller has a first upper frame 11 and a second upper frame 12 connected by a first bend 13, and both can fold upwards at their connection points with the first bend 13. Similarly, the first lower frame 21 and the second lower frame 22 can fold in opposite directions at their connection points with the third lower frame 23. Furthermore, a first folding section 31 is provided between the first upper frame 11 and the first lower frame 21, and a second folding section 32 is provided between the second upper frame 12 and the second lower frame 22. When the first upper frame 11 folds upwards at its connection point with the first bend 13, the first folding section 31 will cause the first lower frame 21 to fold upwards at its connection point with the third lower frame 23. Likewise, when the second upper frame 12 folds upwards, it will also cause the second lower frame 22 to fold upwards, thus reducing the space occupied by the bassinet for storage. When the device needs to be unfolded, moving the first upper frame 11 and the second upper frame 12 will also unfold the first lower frame 21 and the second lower frame 22. Since a third lower frame 23 is provided between the first lower frame 21 and the second lower frame 22, the lower frame 2 folds into a three-section configuration. Of course, in other embodiments, the third lower frame 23 may itself be two or more sections, resulting in a more natural transition at the bends. The third lower frame 23 provides space between the first lower frame 21 and the second lower frame 22 in the folded state. On one hand, after folding, the first lower frame 21, the second lower frame 22, and the third lower frame 23 are arranged in a parallel U-shape, which occupies less space compared to a two-section V-shaped frame; on the other hand, the awning and fabric cover are less likely to be damaged by compression, and the folded surface is flatter. Of course, in other embodiments, a third upper frame can also be provided between the first upper frame 11 and the second upper frame 12 to achieve a better folded effect. Furthermore, because the first support rod 312 is fixedly connected to the third lower frame 23, in the folded state, the tilt angles of the first upper frame 11, the second upper frame 12, the first lower frame 21, and the second lower frame 22 are consistent with the first support rod 312, allowing the basket to tilt to one side to fit the frame and facilitate folding of the entire vehicle. Additionally, when the second upper frame 12 folds upwards, it applies a force to the first bending part 13, causing it to move downwards. Since the rotation point of the first support rod 312 and the first upper frame 11 is fixed, only one hand is needed to fold the second upper frame 12, which can also fold the entire basket. The first folding part 31 is also equipped with a first connecting rod 311, distributing the connection points with the upper frame 1 and the lower frame 2, resulting in even force distribution and a more stable and reliable structure that is less prone to deformation. This design is simple in structure, low in manufacturing cost, and less prone to malfunctions during use.
