Description

[Technical Field]

[0001] This utility model relates to the field of children's stroller technology, and in particular to a canopy adjustment mechanism for children's strollers. [Background Technology]

[0002] Currently, to adjust the height of the canopy, strollers typically have locking mechanisms at the connection points between the canopy support rod and the backrest on both sides. When adjusting the canopy height, users must simultaneously operate both locking mechanisms on either side of the backrest to unlock them, then move the canopy support rod up or down to the desired position, and finally release the locking mechanisms to lock them in place. However, this method of adjustment requiring both hands has significant drawbacks. In actual use, users often need to hold the stroller steady or supervise the child with one hand, making single-handed operation extremely inconvenient and even posing a safety hazard of the stroller rolling away. Therefore, users must first stabilize the stroller before freeing both hands to complete the adjustment, greatly impacting ease of use and user experience.

[0003] In addition, in existing strollers, the canopy support rod and headrest are adjusted independently. The height of the canopy support rod and the relative height of the headrest to the backrest are related to the height of the child occupant. Therefore, when adjusting the height of the canopy support rod, the height of the headrest also needs to be adjusted. Thus, the solution of adjusting the height of the canopy support rod and the headrest separately is more cumbersome in actual use.

[0004] Therefore, this utility model was developed to address the aforementioned problems. [Utility Model Content]

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a canopy adjustment mechanism for children's strollers. Users only need to operate the adjustment and unlocking operation piece with one hand to coordinate the unlocking action of the locking component. Then, the operation of the adjustment connecting plate drives the canopy support rod to move up and down relative to the backrest to adjust to the desired position. It conforms to ergonomics, significantly improves the user experience, and has the characteristics of convenient and efficient operation and high safety.

Detailed Implementation Methods

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1-9As shown, this utility model discloses a canopy adjustment mechanism for a children's stroller. The stroller includes a frame body 1 and a seat frame 2 detachably or relatively fixedly connected to the frame body 1. The seat frame 2 includes a seat portion 21 and a backrest 22 disposed on the seat portion 21. The canopy adjustment mechanism 3 includes an adjustment connecting plate 31, a canopy support rod 32, an adjustment locking assembly 33, and an adjustment unlocking operation component 34. The adjustment connecting plate 31 is movably and adjustably disposed on the backrest 22 in the up-down direction. The two ends of the canopy support rod 32 are connected to the two sides of the adjustment connecting plate 31 respectively, so that the canopy support rod 32 can move up and down relative to the backrest 22 with the adjustment connecting plate 31. The adjustment locking assembly 33 is disposed between the adjustment connecting plate 31 and the backrest 22 to lock the adjustment connecting plate 31 relative to the backrest 22. The adjustment unlocking operation component 34 is disposed between the adjustment connecting plate 31 and the backrest 22 for one-handed operation by the user and is linked with the adjustment locking assembly 33. During adjustment, the user operates the adjustment unlocking mechanism 34 with one hand to trigger the unlocking action of the adjustment locking component 33, thereby releasing the locking state of the adjustment connecting plate 31 relative to the backrest 22. Then, the user operates the adjustment connecting plate 31 to move the canopy support rod 32 up or down relative to the backrest to the desired position. At this moment, the adjustment locking component 33 locks the adjustment connecting plate 31 backrest 22 again. Therefore, this utility model only requires the user to operate the adjustment unlocking mechanism with one hand to trigger the unlocking action of the adjustment locking component, and then operate the adjustment connecting plate to move the canopy support rod up and down relative to the backrest to adjust to the desired position. It conforms to ergonomics, significantly improves the user experience, and has the characteristics of convenient and efficient operation and high safety.

[0034] like Figure 1-6 As shown, both sides of the adjusting connecting plate 31 are connected to both ends of the canopy support rod 32 via support joints 35. The support joints 35 are configured to lock the canopy support rod 32 relative to the adjusting connecting plate 31 at any of the multiple angle positions. This embodiment, by adjusting the angle of the support joints 35, changes the extension angle of the canopy support rod 32, thereby precisely controlling the pitch angle of the canopy's leading edge to meet different usage requirements and scenario needs, demonstrating high practicality.

[0035] like Figure 6 , 7As shown, for reliable and precise adjustment, the support joint 35 includes a first support joint block 351 located on the side of the adjustment connecting plate 31 and exposed on the side of the backrest 22, and a second support joint block 352 located at the end of the canopy support rod 32 and pivotally connected to the first support joint block 351. The support joint 35 also includes an adjustment gear 353 located on the opposite sides of the first support joint block 351 and the second support joint block 352 and mutually locking and adjusting with each other. Furthermore, a support elastic element is provided between the first support joint block 351 and the second support joint block 352 to ensure that the adjustment gear 353 on the first support joint block 351 and the second support joint block 352 remains reliably engaged.

[0036] like Figure 6 , 7 As shown, an adjustment guide assembly 4 is provided between the adjustment connecting plate 31 and the backrest 22 to guide the movement path of the adjustment connecting plate 31. Specifically, the adjustment guide assembly 4 includes an adjustment guide elongated hole 41 provided on the backrest 22 and extending along the vertical direction of the backrest 22, and an adjustment guide protrusion 42 provided on the adjustment connecting plate 31 and slidably placed within the adjustment guide elongated hole 41. This adjustment guide assembly provides a clear trajectory limit for the vertical movement of the adjustment connecting plate, preventing the adjustment connecting plate from wobbling back and forth or left and right during movement. This allows the user to easily push and pull the canopy with only a small amount of force when operating with one hand, making the whole process smooth and improving the operating feel.

[0037] like Figure 5-8 As shown, in order to ensure reliable locking and convenient unlocking, the adjustment locking assembly 33 includes a plurality of adjustment locking parts 331 spaced apart on the backrest 22 along the vertical direction and adjustment locking members 332 movably disposed on the adjustment connecting plate 31 and locked in cooperation with the corresponding adjustment locking parts 331. The adjustment unlocking operation member 34 is disposed on the adjustment connecting plate 31 and is linked with the adjustment locking member 332.

[0038] like Figure 5-8 As shown, in order to achieve automatic and reliable locking and improve safety, the adjusting locking assembly 33 also includes an adjusting elastic element 333 disposed between the adjusting locking element 332 and the adjusting connecting plate 31 for driving the adjusting locking element 332 to elastically reset.

[0039] like Figure 6 , 8As shown, the adjusting lock 332 and the adjusting unlocking operation 34 are provided with interlocking unlocking linkage inclined parts 341, and the movement direction of the adjusting lock 332 relative to the adjusting connecting plate 31 is perpendicular to the movement direction of the adjusting unlocking operation 34 relative to the adjusting connecting plate 31. In this embodiment, through the interlocking cooperation of the two unlocking linkage inclined parts 341, the vertical or near-vertical pressing force of the user's operation of the adjusting unlocking operation 34 is smoothly and efficiently converted into the unlocking force that drives the adjusting lock 332 to move horizontally or laterally. This allows the adjusting unlocking operation 34 to be set in an ergonomic position, such as the top or side of the backrest, which is convenient for one-handed pressing. The lateral movement of the adjusting lock 332 is best suited for stable and reliable insertion and removal locking with the adjusting lock part on the backrest, greatly optimizing the convenience of operation.

[0040] like Figure 1-6 As shown, for convenient and efficient operation, a backrest window 221 is provided at the rear of the backrest 22; an adjustment operation handle 311 that passes through the backrest window 221 is fixedly connected to the adjustment connecting plate 31, and the adjustment lock 332 and the adjustment unlocking operation 34 are both provided on the adjustment operation handle 311.

[0041] like Figure 1-8 As shown, to improve safety, the adjustment handle 311 is equipped with a shield 312 for covering the backrest window 221. In this embodiment, the shield 312 can dynamically cover the movable gap between the backrest window 221 and the adjustment connecting plate, effectively preventing children from sticking their fingers into the backrest window out of curiosity and avoiding injury from the internal moving parts; at the same time, the shield 312 also prevents large foreign objects from getting stuck in the internal moving parts, causing adjustment malfunction or damage.

[0042] like Figure 1-7 As shown, the backrest 22 or the adjusting connecting plate 31 is provided with a headrest 5 that can move in coordination with the adjusting connecting plate 31 relative to the backrest 22. In this embodiment, the headrest 5 is provided on the adjusting connecting plate 31, so the user only needs to operate one adjustment and unlocking operation. While adjusting the height of the canopy support rod, the headrest will automatically follow the adjusting connecting plate to move to the appropriate position, eliminating the need for two separate unlocking, adjustment and locking operations, which greatly improves convenience.
