Description

[Technical Field]

[0001] This utility model relates to the field of children's travel products technology, and in particular to a children's stroller with a convenient seat frame and frame that can be unlocked and separated. [Background Technology]

[0002] Currently, to ensure reliable connection and quick separation between the seat frame and the stroller frame, strollers generally incorporate locking mechanisms between the corresponding connecting seats on both sides of the seat frame and the stroller frame. These locking mechanisms include latches or hooks on the seat frame adapters and locking slots or holes on the connecting seats. During installation, the seat frame adapters on both sides are aligned with the connecting seats on the stroller frame and pressed down. The latches automatically engage with the locking slots under spring pressure, completing the locking process. To unlock, the user must simultaneously operate the unlock buttons on both sides of the seat frame to retract the latches on each side, allowing the entire seat frame to be lifted and separated. However, this traditional dual-sided independent locking design has significant drawbacks:

[0003] 1. Inconvenient operation, requiring two hands: Because the locking mechanisms are located on both sides, both unlocking buttons must be pressed simultaneously with both hands to unlock. When a user needs to hold a child with one hand, or is carrying other items with the other hand, it is almost impossible to complete the unlocking operation independently, causing great inconvenience to the user.

[0004] 2. Safety hazards exist: If the user only unlocks one side of the seat due to inconvenience or negligence, while the other side remains locked, forcibly pulling the seat frame may damage the components, or even cause the seat frame to fall off unexpectedly due to force on one side, posing a safety threat to children.

[0005] 3. Poor user experience: The cumbersome steps of two-handed operation reduce the product's usability and cannot meet users' needs for quick operations such as one-click unlocking.

[0006] Therefore, this utility model was developed to address the aforementioned problems. [Utility Model Content]

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stroller that allows for easy unlocking and separation of the seat frame and the stroller frame. The user only needs to operate the unlocking mechanism to move it relative to the seat, which will simultaneously release the adapter locks on both sides, thereby releasing the locking state of the adapter locking components on both sides. Then, the user can operate the unlocking mechanism to lift the seat frame upwards and separate it from the stroller frame. Therefore, this invention allows the user to unlock and separate the seat frame and the stroller frame with only one hand. The unlocking operation is convenient, safe and reliable, and the user experience is significantly improved.

[0008] To solve the above-mentioned technical problems, this utility model provides a child stroller that facilitates the unlocking and separation of the seat frame and the frame, including a seat part 1 and a backrest 2 provided on the seat part 1. The seat part 1 has a seat joint seat 11, and the backrest 2 has a backrest joint seat 21 that is pivotally connected to the seat joint seat 11 around a joint pivot 10. A seat frame adapter 3 for detachably connecting to a frame connecting seat 110 of the frame 100 is pivotally connected to the outer side of the seat joint seat 11 around the joint pivot 10. Adapter locking components 4 for locking the two are respectively provided between the seat frame adapter 3 and the frame connecting seat 110 on both sides. The adapter locking component 4 includes an adapter locking part 41 provided on the frame connecting seat 110 and an adapter locking member 42 that is slidably provided on the seat frame adapter 3 and coaxial with the joint pivot 10 and is used for locking with the adapter locking part 41. Unlocking operation members 45 that are movably provided on the seat part 1 and linked with the adapter locking members 42 on both sides are provided.

[0009] As described above, a child stroller that facilitates the unlocking and separation of the seat frame and the frame has one end of the unlocking operation member 45 hinged to the seat part 1, and the other end of the unlocking operation member 45 is linked to the two side adapter locks 42 respectively through unlocking linkage members 44.

[0010] As described above, a child stroller that facilitates the unlocking and separation of the seat frame and the frame is provided with an unlocking and resetting elastic element between the end of the unlocking operation member 45 and the seat part 1 for driving the unlocking operation member 45 to rotate and reset.

[0011] As described above, in a stroller that facilitates the unlocking and separation of the seat frame and the frame, during the upward flipping of the unlocking operation member 45 relative to the seat part 1, the unlocking operation member 45 releases the adapter lock member 42 through the unlocking linkage member 44. When the adapter lock member 42 is in the unlocked state, the adapter lock member 42 restricts the unlocking operation member 45 from continuing to flip upward through the unlocking linkage member 44.

[0012] As described above, a child stroller that facilitates the unlocking and separation of the seat frame and the frame has a accommodating mounting groove 12 on the seat part 1 for installing an unlocking operation member 45, and the upper surface of the unlocking operation member 45 is not higher than the upper port surface of the accommodating mounting groove 12.

[0013] As described above, in a stroller that facilitates the unlocking and separation of the seat and frame, the adapter lock 42 is slidably inserted within the joint pivot 10.

[0014] As described above, a child stroller that facilitates the unlocking and separation of the seat frame and the frame is provided with an adapter locking elastic element 43 between the adapter lock 42 and the joint pivot 10 for driving the adapter lock 42 to slide and reset.

[0015] As described above, a child stroller that facilitates the unlocking and separation of the seat frame and the frame has a guide recess 120 at the upper end of the frame connecting seat 110 and above the adapter lock part 41, which guides the adapter lock part 42 during the connection between the seat adapter 3 and the frame connecting seat 110.

[0016] As described above, a stroller that facilitates the unlocking and separation of the seat frame and the frame includes a guide recess 120 comprising a guide inclined wall 121 and two blocking walls 122 located on both sides of the guide inclined wall 121. During the connection process between the seat frame adapter 3 and the frame connecting seat 110, the guide inclined wall 121 abuts against the end of the adapter lock 42, forcing the adapter lock 42 to retract into the joint pivot 10. The two blocking walls 122 and the adapter lock 42 are engaged in a blocking and limiting cooperation.

[0017] As described above, a child stroller that facilitates the unlocking and separation of the seat frame and the frame has a frame connecting seat 110 with a snap-fit ​​block structure that is narrow at the top and wide at the bottom, and a seat frame adapter 3 with a snap-fit ​​groove 31 that engages with the snap-fit ​​block structure.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. In this utility model, the user only needs to operate the unlocking mechanism to move relative to the seat, which will simultaneously release the adapter locks on both sides, thereby releasing the locking state of the adapter locking components on both sides. Then, the user operates the unlocking mechanism to lift the seat frame upward and separate it from the frame. Therefore, this utility model only requires the user to operate the unlocking mechanism with one hand to unlock and separate the seat frame from the frame. The unlocking operation is convenient, safe and reliable, and the user experience is significantly improved.

[0020] 2. This utility model allows the adapter lock to be slidably inserted into the joint pivot, eliminating the need for additional installation space.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1-7 As shown, this utility model discloses a child stroller with a convenient seat frame and frame that can be unlocked and separated. It includes a seat part 1 and a backrest 2 provided on the seat part 1. The seat part 1 has a seat joint seat 11, and the backrest 2 has a backrest joint seat 21 that is pivotally connected to the seat joint seat 11 around a joint pivot 10. A seat frame adapter 3 for detachably connecting to a frame connecting seat 110 of the frame 100 is pivotally connected to the outside of the seat joint seat 11 around the joint pivot 10. Adapter locking components 4 for locking the two are respectively provided between the seat frame adapter 3 and the frame connecting seat 110 on both sides. The adapter locking component 4 includes an adapter locking part 41 provided on the frame connecting seat 110 and an adapter locking member 42 that is slidably provided on the seat frame adapter 3 and coaxial with the joint pivot 10 and is used to lock and engage with the adapter locking part 41. Unlocking operation members 45 that are movably provided on the seat part 1 and linked with the adapter locking members 42 on both sides are provided. In this invention, the user only needs to operate the unlocking mechanism to move relative to the seat, which will simultaneously release the adapter locks on both sides, thereby releasing the locking state of the adapter locking components on both sides. Then, the user operates the unlocking mechanism to lift the seat frame upward and separate it from the frame. Therefore, this invention only requires the user to operate the unlocking mechanism with one hand to unlock and separate the seat frame from the frame. The unlocking operation is convenient, safe and reliable, and the user experience is significantly improved.

[0033] In this invention, the adapter lock is coaxially arranged with the joint pivot, which can effectively avoid interference between the retraction and extension movements of the seat components and ensure smooth retraction and extension.

[0034] In this invention, the backrest joint seat 21 and the seat joint seat 11 are provided with a backrest locking assembly for locking the backrest joint seat 21 relative to the seat joint seat 11, and a seat locking assembly is provided between the seat joint seat 11 and the seat frame adapter 3 for locking the seat joint seat 11 relative to the seat frame adapter 3. The structure of the backrest locking assembly and the seat locking assembly can be found in the relevant structure of a foldable stroller with application number 202321203527.5, and will not be described in detail here.
