Description

Technical Field

[0001] This invention relates to the field of children's products technology, specifically an automatic folding mechanism for the canopy of a children's stroller. Background Technology

[0002] Currently, strollers, as a means of transportation for children, require manual pushing and pulling and have become an indispensable item in a child's growth process. Most strollers on the market can be folded or unfolded, and they usually have a canopy on top to block strong sunlight and rain / snow.

[0003] Existing stroller canopy structures generally require manual operation by the user and cannot be automatically unfolded or folded, resulting in poor usability. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic folding mechanism for the canopy of a children's stroller to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic folding canopy mechanism for a children's stroller includes a frame. Two opposing lower push rods are fixedly mounted on the surface of the frame. An upper push rod is slidably mounted on the top of the two lower push rods. A handle is provided at the top of the upper push rod. Slide plates are slidably mounted on the opposite side walls of the two lower push rods. A base is rotatably mounted on the surface of the slide plates. A fixed canopy rod is fixedly mounted on the two slide plates. A movable canopy rod is fixedly mounted on the two bases. The surfaces of the fixed and movable canopy rods are covered with a canopy cloth. A pull rope is fixedly mounted on the side wall of the lower push rod. The end of the pull rope away from the lower push rod is connected to the movable canopy rod. A positioning component connected to the slide plate is provided inside the lower push rod. The positioning component is used to adjust the position of the slide plate on the surface of the lower push rod.

[0007] As a further aspect of the present invention: the positioning component includes a connecting groove on the side wall of the lower push rod, a strip-shaped slot on the side wall of the upper push rod, and a locking block fixedly installed on the side wall of the sliding plate, the locking block passing through the connecting groove and inserted into the slot.

[0008] As a further aspect of the present invention, the upper push rod has an inverted U-shaped structure.

[0009] Compared with existing technologies, the advantages of this invention are: when folding the frame, by setting up a sliding plate, base, pull rope, and positioning component to work together, the movable canopy rod can be controlled to automatically rotate towards the fixed canopy rod, thereby automatically folding the canopy covering the surfaces of the movable and fixed canopy rods, effectively improving the usability of the stroller. It solves the problem that existing stroller canopy structures generally require manual operation by the user and cannot automatically unfold or fold, resulting in poor usability.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0015] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3The diagram shows a structural diagram of an automatic folding canopy mechanism for a children's stroller according to an embodiment of the present invention. It includes a frame 1, with two opposing lower push rods 2 fixedly mounted on the surface of the frame 1. An upper push rod 3 is slidably mounted on the top of the two lower push rods 2. A handle 4 is provided at the top of the upper push rod 3. Slide plates 5 are slidably mounted on the opposite side walls of the two lower push rods 2. A base 6 is rotatably mounted on the surface of the slide plates 5. A fixed canopy rod 7 is fixedly mounted on the two slide plates 5. A movable canopy rod 8 is fixedly mounted on the two bases 6. The surfaces of the fixed canopy rod 7 and the movable canopy rod 8 are covered with a canopy cloth. A pull rope 9 is fixedly mounted on the side wall of the lower push rod 2. The end of the pull rope 9 away from the lower push rod 2 is connected to the movable canopy rod 8. A positioning component 10 connected to the slide plates 5 is provided inside the lower push rod 2. The positioning component 10 is used to adjust the position of the slide plates 5 on the surface of the lower push rod 2.

[0017] In use, the user operates the handle 4 to pull the upper push rod 3 diagonally upward on the surface of the lower push rod 2. The upper push rod 3 cooperates with the positioning component 10 to drive the slide plate 5 to move upward a certain distance synchronously on the side wall of the lower push rod 2. At this time, the movable canopy rod 8 can be easily pushed to rotate away from the fixed canopy rod 7. At this time, the canopy between the movable canopy rod 8 and the fixed canopy rod 7 unfolds. When the trolley needs to be folded and stored, the user operates the handle 4 to push the upper push rod 3 diagonally downward on the surface of the lower push rod 2. The upper push rod 3 cooperates with the positioning component 10 to drive the slide plate 5 to move downward rapidly synchronously on the side wall of the lower push rod 2. When the slide plate 5 moves downward, it drives the base 6 to move synchronously, thereby adjusting the position of the movable canopy rod 8. At this time, the pull rope 9 applies a pulling force to the movable canopy rod 8, which can pull the movable canopy rod 8 to automatically rotate towards the fixed canopy rod 7. At this time, the canopy between the movable canopy rod 8 and the fixed canopy rod 7 automatically folds.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the positioning component 10 includes a connecting groove 101 opened on the side wall of the lower push rod 2, a strip-shaped slot 103 opened on the side wall of the upper push rod 3, and a locking block 102 fixedly installed on the side wall of the slide plate 5. The locking block 102 passes through the connecting groove 101 and is inserted into the slot 103.

[0019] When the upper push rod 3 is pulled upward, the slot 103 moves upward simultaneously. When the bottom of the slot 103 contacts the block 102, the slot 103 restricts the block 102, and the upper push rod 3 drives the slide plate 5 to move upward simultaneously. When the upper push rod 3 is pushed downward, the slot 103 moves downward simultaneously. When the top of the slot 103 contacts the block 102, the slot 103 restricts the block 102 again, and the upper push rod 3 drives the slide plate 5 to move downward simultaneously.

[0020] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the upper push rod 3 has an inverted U-shaped structure.

[0021] The working principle of this invention is as follows: During use, the user operates the handle 4 to pull the upper push rod 3, which moves obliquely upwards on the surface of the lower push rod 2. Simultaneously, the slot 103 moves upwards. When the bottom of the slot 103 contacts the locking block 102, the slot 103 restricts the locking block 102. The upper push rod 3 drives the sliding plate 5 to move upwards a certain distance. At this time, the movable canopy rod 8 can be easily pushed to rotate away from the fixed canopy rod 7. The canopy between the movable canopy rod 8 and the fixed canopy rod 7 unfolds. When the trolley needs to be folded and stored, the user operates the handle 4 to push... The upper push rod 3 moves diagonally downward on the surface of the lower push rod 2, and the slot 103 moves downward synchronously. When the top of the slot 103 contacts the block 102, the slot 103 restricts the block 102 again. The upper push rod 3 drives the slide plate 5 to move downward rapidly at the side wall of the lower push rod 2. When the slide plate 5 moves downward, it drives the base 6 to move synchronously, thereby adjusting the position of the movable awning rod 8. At this time, the pull rope 9 applies a pulling force to the movable awning rod 8, which can pull the movable awning rod 8 to automatically rotate towards the fixed awning rod 7. At this time, the awning between the movable awning rod 8 and the fixed awning rod 7 is automatically folded.

[0022] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
