Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to a baby stroller with a reversible handle and self-positioning. Background Technology

[0002] In the daily practice of modern parenting, strollers have undeniably become an indispensable tool for parents when taking their infants out. The selection of this tool not only requires strictly meeting the basic needs of stability and safety, ensuring solid protection for the baby in various terrains and environments, but also necessitates multiple characteristics such as compact size, lightweight, and easy folding. This design consideration aims to better adapt to diverse family outing scenarios, easily handling everything from shopping trips and park walks to long-distance travel, bringing a more convenient and comfortable travel experience for parents and babies.

[0003] Most strollers on the market today use swivel wheels in their steering design to achieve flexible steering. However, in actual use, when the stroller turns, the swivel wheels on both sides are prone to getting stuck due to free rotation. For example, when passing through narrow passages, crowded areas, or areas with complex road conditions, users need to frequently and precisely control the stroller's steering. The problem of the swivel wheels getting stuck due to free rotation not only makes steering extremely difficult and increases the burden on parents, but also poses a potential threat to the safety of infants and young children in emergency situations due to the inability to steer flexibly in time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a self-positioning baby stroller with a reversible handle, which aims to improve the problem that the swivel wheels on both sides are prone to getting stuck due to free rotation when the existing baby stroller is turned.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handle-operated self-positioning baby stroller, comprising a frame for supporting the stroller; a seat for the baby to sit on, installed inside the frame; a steering mechanism for assisting the stroller in steering, installed inside the frame, including a control mechanism and a locking mechanism; and a placement mechanism for placing items; the control mechanism includes a connecting rod and a handle, the handle being fixedly connected to the connecting rod, the connecting rod being slidably connected inside the frame, a sliding rod being fixedly connected inside the frame, the sliding rod being slidably connected to the connecting rod, a spring being sleeved on the outer wall of the sliding rod, and a pressure sensor being installed inside the frame; the locking mechanism includes a support frame installed at the bottom of the frame, a rotating shaft being rotatably connected inside the support frame, a universal wheel being installed at the bottom of the rotating shaft, an electromagnet being installed inside the support frame, the electromagnet being controlled by the pressure sensor, a pin being slidably connected inside the rotating shaft, a limit block being fixedly connected to the bottom of the pin, and a spring being sleeved on the outer wall of the pin.

[0006] Furthermore, the placement mechanism includes a crossbar and a storage frame, with the crossbar fixedly connected inside the support frame.

[0007] Furthermore, a fixing post is fixedly connected to the top of the crossbar, and a fixing ring is fixedly connected to the outer wall of the storage frame.

[0008] Furthermore, the fixing ring is sleeved on the outer wall of the fixing column, and the crossbar is internally threaded with a threaded column.

[0009] Furthermore, a knob is fixedly connected to one end of the threaded post, and a connecting block is rotatably connected to the other end of the threaded post.

[0010] Furthermore, a second sliding rod is fixedly connected inside the crossbar, and a transmission rod is rotatably connected inside the connecting block.

[0011] Furthermore, a slider is rotatably connected to one side of the transmission rod, and the slider is slidably connected to the outer wall of the second slide rod.

[0012] Furthermore, a pressure block is fixedly connected to one side of the slider, and the pressure block can slide out of the fixed column and press against the top of the fixed ring.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the pressure sensor can be triggered by rotating the handle of the connecting rod. The pressure sensor can then control the electromagnet on the same side to be energized, causing the pin to overcome the force of the second spring, extend out of the rotating shaft, and insert into the support frame. This fixes the caster wheel on that side while allowing the caster wheel on the other side to rotate freely. This solves the problem that the caster wheels on both sides are prone to getting stuck due to free rotation when the stroller is turned, thus improving the practicality of the stroller.

[0015] 2. In this utility model, the storage frame can be fixed by a fixing ring and a fixing post. The screw post is driven to rotate by a knob, which pushes the connecting block. The connecting block drives the slider to slide along the sliding rod through the transmission rod, thereby driving the pressure block to slide out of the fixing post. The pressure block presses against the fixing ring, thus fixing the storage frame and improving the convenience of disassembling and installing the storage frame. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-6This utility model provides an embodiment of a self-positioning baby stroller with a reversible handle, comprising: a frame 1 for supporting the stroller; a seat 2 for the baby to sit on, installed inside the frame 1; a steering mechanism for turning the stroller, installed inside the frame 1, including a control mechanism and a locking mechanism; and a placement mechanism for placing items. The control mechanism includes a connecting rod 3 and a handle 4, the handle 4 being fixedly connected to the connecting rod 3, the connecting rod 3 being slidably connected inside the frame 1, and a sliding rod 10 being fixedly connected inside the frame 1. 10 is slidably connected to the connecting rod 3. A spring 9 is sleeved on the outer wall of the sliding rod 10. A pressure sensor 11 is installed inside the frame 1. The locking mechanism includes a support frame 5, which is installed at the bottom of the frame 1. A rotating shaft 12 is rotatably connected inside the support frame 5. A caster wheel 7 is installed at the bottom of the rotating shaft 12. An electromagnet 13 is installed inside the support frame 5. The electromagnet 13 is controlled by the pressure sensor 11. A pin 14 is slidably connected inside the rotating shaft 12. A limit block 16 is fixedly connected to the bottom of the pin 14. A spring 15 is sleeved on the outer wall of the pin 14.

[0026] Specifically, in actual use of this baby stroller, the operator can move the stroller by holding and pushing the handle 4 located at the top of the stroller and using the flexible omnidirectional wheels 7 at the bottom. However, when it is necessary to change the direction of travel of the stroller, the operator needs to apply a certain steering force to the handle 4. This force will cause the handle 4 itself to rotate accordingly. As the handle rotates, the connecting rod 3 on one side connected to it will rotate forward accordingly, while at the same time, the connecting rod 3 on the other side will rotate backward. At this time, the forward-moving connecting rod 3 will slide smoothly on the track of the slide rod 10, and in this process, the pressure sensor 11 set on the slide rod 10 will be precisely triggered. Once the pressure sensor 11 is triggered, it immediately controls the electromagnet 13 on the same side to be energized. The electromagnet 13 then generates a magnetic force, which pulls the pin 14 from its rest position, causing it to overcome the elastic force applied by the spring 15, extend from the rotating shaft 12, and insert into the internal structure of the support frame 5. In this way, the rotating shaft 12 is firmly locked and cannot rotate inside the support frame 5. Consequently, the caster 7 on that side also loses the possibility of rotation, while the caster 7 on the other side remains in a state of free rotation. This asymmetrical locking mechanism enables the stroller to have flexible steering function.

[0027] When installing the storage frame 8, the operator first needs to align the fixing rings 17 designed on both sides of the storage frame 8 and put them onto the fixing post 18 at the top of the crossbar 6. Then, by rotating the knob 25, the rotation of the knob 25 will drive the threaded post 24 connected to it to rotate together. The rotation of the threaded post 24 will push the connecting block 23 to move linearly on the preset track. The movement of the connecting block 23 will be transmitted through the transmission rod 22, further pushing the slider 21 to slide smoothly on the slide bar 20. Finally, the movement of the slider 21 will drive the pressure block 19 to slide out from the inside of the fixing post 18 and press on the fixing ring 17, thereby ensuring that the storage frame 8 is firmly fixed on the crossbar 6 for safe and convenient use.

[0028] Working principle: When using this stroller, it can be pushed by the handle 4 and moved by the casters 7 at the bottom. However, when the stroller needs to be turned, the turning force acts on the handle 4, causing it to rotate. This causes the connecting rod 3 on one side of the handle 4 to rotate forward, while the connecting rod 3 on the other side rotates backward. The forward-moving connecting rod 3 slides along the slide bar 10, triggering the pressure sensor 11. This energizes the electromagnet 13 on the same side, causing the electromagnet 13 to attract the pin 14. The pin 14 then overcomes the force of the spring 15, extends out of the rotating shaft 12, and inserts into the support frame 5, thus preventing the rotating shaft 12 from rotating inside the support frame 5. This prevents the caster wheel 7 on one side from rotating, while allowing the caster wheel 7 on the other side to rotate freely, thus enabling the stroller to turn. When installing the storage frame 8, the fixing rings 17 on both sides of the storage frame 8 can be fitted onto the fixing post 18 at the top of the crossbar 6. Then, the knob 25 is turned, causing the threaded post 24 to rotate. The threaded post 24 will push the connecting block 23 to move, and the connecting block 23 will push the slider 21 through the transmission rod 22, causing the slider 21 to slide along the slide bar 20. Thus, the slider 21 will drive the pressure block 19 to slide out of the fixing post 18 and press it against the fixing ring 17, thereby fixing the storage frame 8 on the crossbar 6 for use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
