Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a structure for a children's stroller with a lift-up canopy. [Background Technology]
[0002] Sunshades effectively shield strollers from direct sunlight, providing children with an external protective barrier. However, traditional stroller sunshade height adjustment mechanisms suffer from several problems. Their components are too simple, resulting in unstable and inconvenient height adjustments. They lack the ability to adjust the height of both sides of the canopy simultaneously, and cannot quickly and securely fix the adjusted area. This lack of stability and locking mechanism increases the burden on users and compromises children's safety. Furthermore, the ease of adjustment is nonexistent. Therefore, developing a stroller sunshade height adjustment mechanism that addresses these issues is imperative. [Utility Model Content]

[0016] The beneficial effects of this utility model compared with the prior art are:
[0017] This utility model proposes a structure for a child stroller's adjustable canopy. During operation, the guide slide is pushed along the backrest frame. As the latch gradually moves to the protruding part, the protruding part is compressed and deforms towards the empty space. When the latch engages with the protruding part, the protruding part returns to its original position, thus fixing the movable canopy assembly in the seat position. The protruding parts are arranged along the guide strip. By moving the latch to connect with protruding parts at different positions, the position of the movable canopy assembly can be adjusted, achieving height adjustment. Utilizing an elastic buckle, the height of the movable canopy assembly can be quickly adjusted. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] The preferred embodiment provided by this utility model is as follows: Figures 1-3 As shown, a children's stroller with a lift-up canopy structure includes a seat 1 and a movable canopy assembly 2; the seat 1 includes a seat frame 3 and a backrest frame 4, the seat frame 3 and the backrest frame 4 being hinged together so that the two can be folded relative to each other;
[0025] The movable canopy assembly 2 includes a guide slide 5, a flip frame 6, and a support frame 7. The movable canopy assembly 2 is connected to the backrest frame 4 via the guide slide 5, and the guide slide 5 slides along the backrest frame 4 to change the position of the movable canopy assembly 2 on the backrest frame 4.
[0026] The backrest frame 4 is provided with a guide strip 41, and the guide member 5 is connected to the guide strip 41 so that the guide member 5 can move along the guide strip 41. A protrusion 42 and a latch 43 are provided between the guide member 5 and the guide strip 41. The protrusion 42 and the latch 43 are connected to restrict the sliding of the guide member 5 relative to the backrest frame 4.
[0027] The guide strip 41 includes an end 44 and a guide strip 45. The guide strip 41 is an integral structure. The end 44 is located at both ends of the guide strip 45 and is an annular frame. The end 44 is sleeved and fixed to the rod of the backrest frame 4. The guide strip 41 is connected to the backrest frame 4 through the end 44. The protrusion 42 is provided on the side of the guide strip 45 and is arranged along the guide strip 45. The protrusion 42 is triangular in shape. The latch 43 is provided in the opening slot 46. The shape and size of the latch 43 correspond to the shape and size of the protrusion 42. The latch 43 is protruding so that the latch 43 and the protrusion 42 are closer together for better connection. The guide strip 45 has a gap 47 located at the position of the protrusion 42 so that the protrusion 42 can deform.
[0028] The guide slide 5 includes a first insertion part 51 and a second insertion part 52. The support frame 7 is installed in the first insertion part 51, and the backrest frame 4 passes through the second insertion part 52, so that the guide slide 5 slides along the backrest frame 4 to change the position of the movable canopy assembly 2. The first insertion part 51 is provided with a blind hole 53 for the support frame 7 to be inserted, and the second insertion part 52 is provided with a through cavity 54 for the backrest frame 4 to pass through, and the through cavity 54 is provided with an opening groove 46 for the guide strip 45 to pass through.
[0029] The guide slide 5 extends into a connecting joint 55. The tilting frame 6 includes a rotating member 61 and a support rod 62. The support rod 62 is inserted into the rotating member so that the support rod 62 rotates together with the rotating member 61. The rotating member 61 is pivotally connected to the connecting joint 55 to mount the tilting frame 6 onto the guide slide 5. Both the connecting joint 55 and the rotating member 61 are provided with teeth 63, and the teeth 63 of the connecting joint 55 and the rotating member 61 are connected. The meshing connection of the teeth 63 allows for easy adjustment of the rotation angle of the tilting frame 6.
[0030] The movable canopy assembly 2 is equipped with a canopy, which adopts the existing canopy structure of strollers. Since the canopy is an existing product, it is not marked in the diagram. This solution mainly describes the component structure supporting the canopy. The support frame 7 is fixed to the first insertion part 51. One end of the canopy is fixed to the support frame 7, and the other end is fixed to the flip frame 6. The rotating part 61 rotates relative to the guide slide 5 to drive the canopy connected to the support frame 7 and the flip frame 6 to unfold or retract. To further adjust the position of the movable canopy assembly 2 on the seat 1, the movable canopy assembly 2 achieves lifting and lowering via the guide slide 5. During operation, the guide slide 5 is pushed along the backrest frame 4. When the latch 43 gradually moves to the position of the protrusion 42, the protrusion 42 is compressed and deformed towards the empty space 47. When the latch 43 engages with the protrusion 42, the protrusion 42 returns to its original position, thereby fixing the movable canopy assembly 2 in the position of the seat 1. The protrusions 42 are arranged along the guide strip 45. When the latch 43 moves to connect with the protrusions 42 at different positions, the position of the movable canopy assembly 2 can be adjusted to achieve height adjustment.
