Abstract
Description
Technical Field
[0001] This utility model belongs to the field of children's stroller technology, and in particular relates to a children's stroller bassinet locking mechanism. Background Technology
[0002] This baby stroller bassinet is like a mobile cradle of comfort. Made of lightweight, breathable, and skin-friendly fabric, its spacious and soft interior provides a safe and comfortable sleeping environment for your baby, just like in the womb. The adjustable windproof sunshade can flexibly adapt to weather changes, and with the reinforced base and shock absorption system, it remains stable even while being pushed around.
[0003] Most existing baby stroller bassinets use snap-on or pin-type locking structures, which often result in loose locks or inconvenient operation during use. These structures typically use elastic elements or rotating pins to secure the stroller frame, but unlocking often requires both hands or considerable force, making it inconvenient for parents to operate with one hand. In addition, some locking components are installed in exposed positions, making them easy for children to accidentally touch, posing a certain safety hazard. Furthermore, because the locking points and frame pivots are located separately, the structure is complex and the stress is uneven, which can easily cause component deformation or wear, affecting the service life. Utility Model Content
[0004] This utility model provides a locking mechanism for a child stroller bassinet, aiming to solve the problem that existing child stroller bassinets mostly use buckle or pin-type locking structures, which often result in loose locks or inconvenient operation during use. Such structures usually use elastic elements or rotating pins to fix the stroller frame, but unlocking often requires the cooperation of both hands or considerable force, making it inconvenient for parents to operate with one hand. At the same time, some locking parts are installed in exposed positions, which are easily touched by children, posing certain safety hazards.
[0005] This utility model is implemented as follows: a child stroller bassinet locking mechanism includes a front armrest seat, a front frame, a rear frame, an unlocking component, a gear, and a fixing seat. The fixing seat is hinged to the rear frame, the front frame, and the front armrest seat at the same center. The gear is disposed between the rear frame and the fixing seat and can slide inside. The unlocking component is disposed on the rear frame and can slide along the rear frame. The unlocking component has an inclined surface A, and the gear has an inclined surface B, with inclined surface A and inclined surface B in contact and engagement.
[0006] Preferably, the unlocking component engages with a sliding groove on the rear frame via a slider, thereby achieving guided movement along the direction of the sliding groove.
[0007] Preferably, the end of the gear is provided with a limiting flange, and the limiting flange is used to prevent the gear from disengaging from the fixed seat during sliding.
[0008] Preferably, a reset spring is provided between the unlocking component and the gear, and the reset spring pushes the gear back to its original position after the unlocking component is released.
[0009] Preferably, the angle between inclined plane A and inclined plane B is 30 to 45 degrees, and the angle is set to ensure the push-away contact relationship between the inclined planes.
[0010] Preferably, the fixed base is provided with a sliding cavity, and the gear slides along the axial direction of the sliding cavity and is guided and engaged with the inner wall of the rear frame.
[0011] Preferably, the front armrest seat, the front frame, and the rear frame form an integral connecting frame, and the connecting frame is rotatably connected to the fixed seat through a central hinge point.
[0012] Compared with related technologies, the child stroller bassinet locking mechanism provided by this utility model has the following advantages:
[0013] In this invention, a reliable mechanical locking is achieved by setting a sliding gear between the rear frame and the fixed seat. The inclined surface fit structure between the unlocking component and the gear makes the unlocking process smooth and stable. Unlocking can be completed by a one-way sliding action, which is easy to operate. The fixed seat, front frame, rear frame and front armrest share the same central hinge point, which reduces the number of parts and makes the structure more compact. This design not only improves the overall strength, but also keeps the frame posture stable during locking and unlocking. The mechanism can be hidden inside the frame to avoid external interference, and has good aesthetics and safety. Attached Figure Description

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0022] A preferred embodiment of the child stroller bassinet locking mechanism provided by this utility model is, for example... Figures 1 to 5 As shown: A child stroller bassinet locking mechanism includes a front armrest seat 1, a front frame 2, a rear frame 3, an unlocking component 4, a gear 5, and a fixing seat 6. The fixing seat 6 is hinged to the rear frame 3, the front frame 2, and the front armrest seat 1 at the same center. The gear 5 is disposed between the rear frame 3 and the fixing seat 6 and can slide inside. The unlocking component 4 is disposed on the rear frame 3 and can slide along the direction of the rear frame 3. The unlocking component 4 is provided with an inclined surface A7, and the gear 5 is provided with an inclined surface B8, and the inclined surface A7 and the inclined surface B8 are in contact and engaged.
[0023] In this embodiment, the inclined surfaces A7 and B8 between the unlocking member 44 and the gear 55 cooperate so that when the unlocking member 44 slides along the rear frame 33, the inclined surface A7 can push the gear 55 to generate axial displacement, thereby realizing the linear conversion of locking and unlocking. This inclined surface cooperation can complete the sliding of the gear 5 with a small operating force, reduce unlocking resistance and improve the smoothness of operation.
[0024] In a further preferred embodiment of the present invention, the unlocking member 4 cooperates with the sliding groove on the rear frame 3 through the slider, thereby realizing the guided movement along the direction of the sliding groove. The end of the gear 5 is provided with a limiting flange, and the limiting flange is used to prevent the gear 5 from disengaging from the fixed seat 6 during the sliding process. A reset spring is provided between the unlocking member 4 and the gear 5, and the reset spring pushes the gear 5 back to its original position after the unlocking member 4 is released.
[0025] In this embodiment, the gear 55 slides within the sliding cavity of the fixed base 66. The sliding surfaces of the two cooperate with each other, so that the gear 55 maintains stable linear motion during locking or returning, avoiding tilting or jamming. This cooperation improves the motion accuracy and ensures the repeatability of the locking position.
[0026] In a further preferred embodiment of this utility model, the angle between inclined plane A7 and inclined plane B8 is 30 degrees to 45 degrees. The angle is set to ensure the push-away contact relationship between the inclined planes. The fixed seat 6 is provided with a sliding cavity. The gear 5 slides along the axial direction of the sliding cavity and is guided and engaged with the inner wall of the rear frame 3. The front armrest seat 1, the front frame 2 and the rear frame 3 form an integral connecting frame, and the connecting frame is rotatably connected to the fixed seat 6 through the central hinge point.
[0027] In this embodiment, the limiting flange on the gear 55 contacts the end wall of the fixed seat 66 at the end of the sliding cavity, thereby limiting the maximum sliding stroke of the gear 5. This engagement can prevent the gear 5 from dislodging and causing the mechanism to fail, while providing a reliable stop positioning for the return process.
[0028] In summary, a reliable mechanical locking is achieved by setting a sliding gear 5 between the rear frame 3 and the fixed seat 6. The inclined surface fit structure between the unlocking part 4 and the gear 5 makes the unlocking process smooth and stable. Unlocking can be completed by a one-way sliding action, which is easy to operate. The fixed seat 6, front frame 2, rear frame 3 and front armrest seat 1 share the same central hinge point, which reduces the number of parts and makes the structure more compact. This design not only improves the overall strength, but also keeps the frame posture stable during locking and unlocking. The mechanism can be hidden inside the frame to avoid external interference, and has good aesthetics and safety.
