Adaptable mounting structure and stroller

Abstract

This application discloses an adapter mounting structure and a stroller. The adapter mounting structure includes an adapter seat, an adapter, a locking member, an unlocking member, a first elastic member, and a second elastic member. The adapter has a usage state where it is engaged with the adapter seat and a disassembled state where it is detached from the adapter seat. The locking member is used to lock the adapter to maintain it in the usage state. The locking member has an unlocking position, a locking position, and an intermediate position between the unlocking position and the locking position. The unlocking member is used to drive the locking member and has an initial position and a hovering position. The unlocking member moves from the initial position to the hovering position, driving the locking member from the locking position to the intermediate position. When the unlocking member is in the hovering position, it interlocks with the locking member to maintain it in the intermediate position. During the separation of the adapter from the adapter seat, the locking member is driven from the intermediate position to the unlocking position, and the unlocking member is released at the same time, maintaining the hovering position of the adapter. This reduces the number of parts, thereby simplifying the structure and reducing the assembly difficulty.

Description

Technical Field

[0001] This application relates to the technical field of children's strollers, specifically an adapter installation structure and a children's stroller. Background Technology

[0002] Existing strollers, such as the one disclosed in patent document CN219857313U, include a frame and a child carrier detachably mounted on the frame. The child carrier and frame are respectively provided with matching adapters and fitting seats. The stroller includes a locking element, an unlocking element, a limiting element, and a triggering element. The locking element is used to prevent the adapter from detaching from the fitting seat. It is movably mounted on the adapter and has a locked state when engaged with the fitting seat and an unlocked state when disengaged from the fitting seat. The unlocking element is movably mounted on the adapter and has a first position that drives the locking element to release the lock and a second position that allows the locking element to be in the locked state. The limiting element is movably mounted on the adapter and, when the unlocking element is in the first position, can limit the movement of the unlocking element, causing the locking element to remain in the unlocked state. The triggering element is located on the fitting seat and, when the adapter passes the fitting seat, acts on the limiting element to release the restriction on the unlocking element, facilitating disassembly. However, the structure of the locking element, unlocking element, limiting element, and triggering element is too complex, and assembly is cumbersome. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] See Figure 1 and Figure 2 This application provides a stroller, including a frame 100 and a support device 200. Wheels are mounted on the bottom of the frame. The support device includes, for example, a child seat or a bassinet. The accompanying drawings show a child seat as the support device. In one embodiment, the stroller further includes an adapter mounting structure disposed between the frame 100 and the support device 200 to achieve a detachable connection between the frame and the support device.

[0047] The frame 100 has an unfolded state and a folded state, and includes a front leg assembly 110, a rear leg assembly 120, and a handlebar assembly 130, which are coaxially hinged about an axis. The frame 100 also includes a locking member for keeping the frame 100 in the unfolded state, and a locking member for releasing the locking member. After the locking member is unlocked, the handlebar assembly 130 and the front leg assembly 110 rotate and move closer to the rear leg assembly 120. The frame 100 also includes a linkage, such as a linkage rod, connecting the handlebar assembly 130 and the front leg assembly 110, so that the handlebar assembly 130 and the front leg assembly 110 fold and unfold in a coordinated manner.

[0048] The front leg assembly 110 includes two front leg bars arranged laterally and a front crossbar connected to the bottom of the two front leg bars. The rear leg assembly 120 includes two rear leg bars arranged laterally and a rear crossbar connected between the bottom of the two rear leg bars. The handle assembly 130 includes two handle bars arranged laterally and a grip bar connected to the top of the two handle bars. The front leg bar, rear leg bar and handle bar on one side are hinged to each other to form a side frame. Specifically, the load-bearing device 200 is installed or removed vertically between the two side frames.

[0049] like Figures 2-7 As shown, in one embodiment, the adapter installation structure includes two adapter seats 300 disposed on two side frames, and adapters 400 disposed on both sides of the support device 200. The adapters 400 have a working state in which they are combined with the adapter seats 300, and a disassembled state in which they are detached from the adapter seats 300. The adapter mounting structure also includes a locking element 410, an unlocking element 420, a first elastic element 430, and a second elastic element (installed inside the adapter and concealed). The locking element 410 is movable and has a locked position, an unlocked position, and an intermediate position between the locked and unlocked positions. In the locked position, the locking element 410 interacts with the adapter base 300 or the adapter 400 (the object of interaction is hereinafter referred to as the counterpart element) to keep the adapter 400 in use. In the unlocked position, the locking element 410 completely disengages from the counterpart element, allowing the adapter 400 to be detached from the adapter base 300. In the intermediate position, the adapter 400 is allowed to be detached from the adapter base 300, but during this process, the counterpart element acts on the locking element 410 to switch its movement from the intermediate position to the unlocked position.

[0050] The unlocking element 420 is used to drive the locking element 410. It is movable and has an initial position and a hovering position. Actual unlocking operation: Both unlocking elements 420 are moved from the initial position to the hovering position by operating both hands, driving the locking element 410 from the locked position to the intermediate position. The unlocking elements 420 and the locking element 410 interlock, so that the unlocking element 420 is held in the hovering position and the locking element 410 is held in the intermediate position. At the same time, the first elastic element 430 and the second elastic element are compressed or stretched to store energy. The external force applied to the unlocking element 420 is released by both hands, preparing for the subsequent disassembly of the carrier device 200. At this time, the carrier device 200 is in a hovering state relative to the frame 100, waiting for disassembly.

[0051] Disassembly Operation: During the lifting of the support device 200 and the separation of the adapter 400 and the fitting base 300, the locking member 410 of the hand component is moved from the middle position to the unlocking position, releasing the interlocking relationship between the unlocking member 420 and the locking member 410. The second elastic member resets to drive the unlocking member 420 from the hovering position to the initial position. After the hand component and the locking member 410 are completely released from their interaction, for example, when the adapter 400 is completely detached from the fitting base 300, the first elastic member 430 resets to drive the locking member 410 from the unlocking position to the locking position.

[0052] The adapter installation structure of this application retains the adapter's suspended state, facilitating subsequent disassembly of the support device. After disassembly, both the locking and unlocking components reset, ready for the next normal installation. While maintaining the original functionality, it reduces the number of parts, simplifies the structure, and lowers assembly difficulty.

[0053] To facilitate assembly and meet the requirements for installation space, in one embodiment, the first elastic element 430 and the second elastic element are cylindrical springs.

[0054] like Figure 3 and Figure 4 In one embodiment, a locking structure is provided between the adapter 400 and the fitting seat 300 to restrict their lateral separation, the lateral separation being parallel to the rotation axis of the frame. As shown in the figure, the locking structure includes a locking block 310 protruding from the fitting seat 300 and a locking groove 401 provided on the adapter 400, with an opening 402 on the adapter 400 for the locking block 310 to enter and exit the locking groove 401.

[0055] In one embodiment, the support device 200 has a folded state that rotates and closes to the rear foot assembly 120 and an unfolded state when carrying a child. The corresponding slot 401 has a circular structure, and the card block 310 protrudes radially outward in a disc shape. In the use state, the adapter 400 can rotate relative to the adapter seat 300 around an axis, thereby realizing the switching of the support device 200 between the folded state and the unfolded state.

[0056] In order to keep the support device 200 stably in the deployed state, such as Figures 3-5 As shown, in one embodiment, the adapter 400 is provided with a locking member 450 that restricts its rotation relative to the adapter seat 300. The locking member 450 is slidably mounted laterally, and the corresponding latching block 310 is provided with a locking groove 311 that engages with the locking member 450. Figure 1 and Figure 2 In one embodiment, the support device 200 includes a seat cushion 210 fixedly connected to the adapter 400 and a backrest 220 rotatably connected to the seat cushion 210. The seat has a stowed state in which the backrest 220 is close to the seat cushion 210 and a support state in which the backrest 220 is away from the seat cushion 210. During the process of the backrest 220 rotating from the support state to the stowed state, the backrest 220 drives the locking member 450 to slide out of the locking groove 311. Under the action of gravity, the support device 200 rotates as a whole to close to the rear leg assembly 120 until it reaches the stowed state.

[0057] Locking member 410 and unlocking member 420 are mounted together in one of the adapter 400 or the fitting 300. In one embodiment, locking member 410 is slidably mounted on adapter 400 along a first direction, and unlocking member 420 is slidably mounted on adapter 400 along a second direction. The first direction is parallel to the axial direction and perpendicular to the second direction. Locking member 450 is arranged vertically, and to avoid assembly interference, the second direction has an angle with the longitudinal direction (vertical direction).

[0058] like Figures 3-14 The locking member 410 has a first locking portion 411 that exposes the coupling adapter 300 of the adapter 400, and a second locking portion 412 located inside the adapter 400 that engages with the unlocking member 420. The adapter 300 is provided with a first locking groove 320 that mates with the first locking portion 411, and the unlocking member 420 is provided with a second locking groove 423 that mates with the second locking portion 412. The first locking groove 320 is a circular groove or an annular groove. When the adapter 400 rotates relative to the adapter 300, the first locking portion 411 rotates within the first locking groove 320.

[0059] like Figures 11-14 As shown, the first locking part 411 is provided with a first guide slope 413. In the middle position and during disassembly, the adapter 300 abuts against the first guide slope 413 to drive the locking member 410 to move from the middle position to the unlocking position.

[0060] The unlocking component 420 includes an operating part 421 and a driving part 422. The driving part 422 is provided with a second locking groove 423. The initial position of the unlocking component 420 relative to the hovering position, with the operating part 421 protruding more from the adapter 400, makes operation more visible. A cooperating second guide ramp 414 is provided between the locking component 410 and the driving part 422, such as... Figures 9-12 As shown, during the unlocking operation, the driving part 422 drives the locking part 410 to slide to the middle position through the second guide slope 414, wherein the second guide slope 414 and the second locking part 412 are seamlessly connected, making the structure more compact.

[0061] like Figure 6 As shown, the locking member 410 is also provided with a third guide slope 415. When the adapter 400 is switched from the disassembled state to the use state (i.e., when the carrier device 200 is installed), the adapter seat 300 abuts against the third guide slope 415 to switch it from the locked position to the unlocked position and compress the first elastic member 430. During this process, the unlocking member 420 is always in the initial position. After the installation is in place, the first elastic member 430 resets and drives the locking member 410 to switch from the unlocked position to the locked position.

[0062] The adapter mounting structure and the carrier device on which the adapter mounting structure is installed in this application retain the function of disassembling the adapter after it is hovered, which facilitates the subsequent disassembly operation of the carrier device. After disassembly, the locking and unlocking parts are reset, waiting for the next normal installation. While keeping the original function unchanged, the number of parts is reduced, the structure is simplified and the assembly difficulty is reduced.

[0063] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0064] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
