Description

Technical Field

[0001] This utility model relates to the field of baby stroller technology, and in particular to a folding baby stroller. Background Technology

[0002] Strollers are primarily designed for young infants and toddlers. When users need to take their infants or toddlers out for activities, they can place them in the stroller, avoiding the fatigue of carrying the child for extended periods. To facilitate portability, strollers often feature a folding mechanism. For example, when the user needs to put the stroller in the car, it can be folded up and unfolded upon arrival at the planned activity location. However, current stroller folding mechanisms are relatively complex, requiring considerable time and effort from users, making them extremely inconvenient to use. Furthermore, existing strollers are quite heavy, and their portability needs improvement.

[0003] Therefore, a foldable stroller is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a foldable stroller.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A folding stroller includes a support rod, a telescopic rod slidably connected to the top of the support rod, a push handle installed on the top of the telescopic rod, first folding brackets rotatably connected to both sides of the bottom of the support rod, rear wheels installed at the bottom of each of the first folding brackets, a sliding sleeve slidably connected to the support rod, a second folding bracket rotatably connected to the sliding sleeve, two sides of the second folding bracket being rotatably connected to two first folding brackets respectively, front wheels installed at the lower ends of both sides of the second folding bracket, a soft seat installed below the push handle, and the bottom of the soft seat being connected to the top of the first and second folding brackets respectively.

[0006] Preferably, in the above-described folding stroller, the bottom of the soft seat is fixedly connected to the top of the first folding bracket.

[0007] Preferably, in the above-mentioned folding stroller, a second hanging rope is provided at the bottom of the soft seat near the end of the support rod, and a hook is provided on the slide, with the second hanging rope hanging on the hook.

[0008] Preferably, in the above-described folding stroller, the open end of the hook is provided with an anti-slip bend angle.

[0009] Preferably, in the above-mentioned folding stroller, the top of the soft seat is provided with a sun visor, and the sun visor is connected to both sides of the end near the telescopic rod. The sun visor connector includes a conduit and a damping shaft. The damping shaft is fixedly connected to the conduit, and the sun visor is connected to the damping shaft. The top of the soft seat is connected to both sides with a first hanging rope. The first hanging rope passes through the inside of the conduit, and the upper end of the first hanging rope is hung on the push handle.

[0010] Preferably, in the above-mentioned folding stroller, both ends of the push handle are provided with hanging ropes, and the upper ends of the two first hanging ropes are respectively hung on the two hanging ropes.

[0011] Preferably, in the above-described folding stroller, a locking switch is installed at the top of the support rod.

[0012] Preferably, in the above-described folding stroller, the support rod is provided with a limiting step, which is adapted to limit the lower end travel of the slide.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1-5 As shown, a folding stroller includes a support rod 1, with a telescopic rod 2 slidably connected to the top of the support rod 1, and the telescopic rod 2 and the support rod 1 cannot rotate relative to each other. A locking switch 3 is installed on the top of the support rod 1. The locking switch 3 is prior art and can be purchased on the market. When the locking switch 3 is open, the telescopic rod 2 can slide and extend within the support rod 1; when the locking switch 3 is closed, the position of the telescopic rod 2 is fixed and it cannot extend or slide.

[0025] A push handle 4 is fixedly installed at the top of the telescopic rod 2. First folding brackets 6 are rotatably connected to both sides of the bottom of the support rod 1, and rear wheels are installed at the bottom of each first folding bracket 6. A sliding sleeve 5 is slidably connected to the support rod 1; the sliding sleeve 5 and the support rod 1 are radially fixed and axially sliding, meaning the sliding sleeve 5 and the support rod 1 cannot rotate relative to each other. A limit step is provided on the support rod 1 to limit the lower travel of the sliding sleeve 5. A second folding bracket 7 is rotatably connected to the sliding sleeve 5; an insertion hole 51 passes through the sliding sleeve 5, and the second folding bracket 7 passes through the insertion hole 51 and is rotatably connected to the sliding sleeve 5. The two sides of the second folding bracket 7 are rotatably connected to two first folding brackets 6 respectively, and front wheels are installed at the lower ends of both sides of the second folding bracket 7. Locking pedals are installed on both front wheels and both rear wheels. The front wheels are steering wheels and their weight is greater than that of the rear wheels. When the frame is lifted by holding the support rod 1, the second folding bracket 7 will rotate under the weight of the front wheels. The first folding bracket 6 and the second folding bracket 7 will rotate around their hinge point, and the sliding sleeve 5 will slide upward along the support rod 1, thereby folding the first folding bracket 6 and the second folding bracket 7 towards the support rod 1.

[0026] A soft seat 8, made of fabric, is installed below the push handle 4, significantly reducing the overall weight of the stroller compared to existing seat cushions and seats. The bottom of the soft seat 8 is connected to the top of the first folding bracket 6 and the second folding bracket 7. The bottom of the soft seat 8 is fixedly connected to the top of the first folding bracket 6. A second hanging rope 13 is provided at the bottom end of the soft seat 8 near the support rod 1, and a hook 52 is provided on the sliding sleeve 5, where the second hanging rope 13 is hooked. The open end of the hook 52 has an anti-slip bend, facilitating the hooking of the rope and preventing it from falling off. First hanging ropes 11 are connected to both sides of the top of the soft seat 8, and hanging rope portions 12 are provided at both ends of the push handle 4, with the upper ends of the two first hanging ropes 11 hooked onto the two hanging rope portions 12 respectively. The soft seat 8 is thus installed on the frame. When the infant sits on the soft seat 8, the first hanging rope 11 and the first folding bracket 6 and the second folding bracket 7 at the bottom support the soft seat 8.

[0027] A sun visor 10 is provided on the top of the soft seat 8. Sun visor connectors 9 are connected to both sides of the end of the sun visor 10 closest to the telescopic rod 2. Each sun visor connector 9 includes a conduit 91 and a damping shaft 92. The damping shaft 92 is fixedly connected to the conduit 91, and the sun visor 10 is connected to the damping shaft 92. The damping shaft 92 is existing technology and can be purchased commercially. A certain torque needs to be applied when the sun visor 10 rotates. Once the sun visor 10 is adjusted to the desired angle, the damping shaft 92 will not rotate without applied force, thus fixing the sun visor 10 at that angle. A first hanging rope 11 passes through the inside of the conduit 91, and its upper end is hooked onto the hanging rope portion 12 on the push handle 4. When the frame is extended, the telescopic rod 2 is in the pulled-up state, and the first hanging rope 11 is in a taut state, thus aligning the conduit 91 and the first hanging rope 11 in a straight line. At this time, the conduit 91 is in a stable state, providing a stable fulcrum support for the sun visor 10. When the frame is retracted, the telescopic rod 2 is slid downwards. At this time, the first hanging rope 11 is not taut and cannot provide stable support for the cable tube 91. Under the influence of gravity at the front end, the front end of the sun visor 10 automatically droops, causing the cable tube 91 to rotate and thus twisting the first hanging rope 11, causing the sun visor 10 to retract automatically. The width of the sun visor 10 is less than the distance between the upper ends of the two first folding brackets 6, so they do not interfere with each other when folded.

[0028] Working principle: When folding up the stroller, first open the locking switch 3, slide the telescopic rod 2 downwards, and the sun visor 10 will automatically droop down under the action of gravity at the front end, and the sun visor 10 will automatically fold up; after the telescopic rod 2 is fully retracted, lock the locking switch 3, hold the support rod 1 and lift the frame, the second folding bracket 7 will rotate under the action of gravity of the front wheel, the first folding bracket 6 and the second folding bracket 7 will rotate around the hinge point of the two, and the sliding sleeve 5 will slide upwards along the support rod 1, so that the first folding bracket 6 and the second folding bracket 7 will fold up towards the support rod 1, and finally the stroller will be completely folded up.
