Description

Technical Field

[0001] The utility model relates to the technical field of baby carriages, in particular to a baby carriage that can be operated with one hand. Background Art

[0002] A hand-pushing stroller is a tool for caring for infants and young children, which has the advantages of low cost and good durability.

[0003] Upon investigation, the Chinese utility model patent with publication number CN220809533U discloses a baby stroller structure, including a seat assembly, a stroller assembly and a connecting rod assembly, wherein the seat assembly is installed on the stroller assembly, the stroller assembly includes a front bracket, a rear bracket and a hand push assembly that are connected as a whole and can pivot relative to each other, the seat assembly can pivot relative to the stroller assembly through the connecting rod assembly, the connecting rod assembly includes a sliding sleeve portion mounted on the front bracket, a bottom support rod mounted between the sliding sleeve portion and the rear bracket, a front support rod for supporting the seat base and a seat base for supporting the seat assembly, the bottom support rod is connected to the rear bracket and can pivot relative to the bottom support rod, the sliding sleeve portion is connected to the front support rod and can pivot relative to the front support rod, the front support rod is connected to the seat base and can pivot relative to the seat base, and the seat base is connected to the hand push assembly and can pivot relative to the front support rod. However, the armrests and the seat of the stroller are connected by means of buckles. When people with upper limb disabilities use the stroller, they need to remove the armrests first before they can safely and conveniently place the baby in the stroller. Since the armrests are U-shaped, they need to press and unlock both sides of the armrests at the same time in the process of opening the armrests before they can be removed. This makes it difficult for people with upper limb disabilities to use the stroller, resulting in a limitation on the people for whom the stroller is suitable.

[0004] Therefore, the present invention provides a baby stroller that can be operated with one hand to solve the above problems. Utility Model Content

[0005] (1) Technical problems solved

[0006] The utility model provides a baby stroller that can be operated with one hand, aiming to solve the problem in the background art that the armrests on the existing baby strollers are U-shaped, which is not conducive to people with upper limb disabilities to remove the armrests from the seat.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a baby stroller that can be operated with one hand, comprising a frame, a seat provided on the top of the frame, a guard bar assembly for protecting the baby provided on the seat, a moving assembly provided on the bottom of the frame, a push rod provided on the rear side of the frame, and a handle fixedly connected to the top end of the push rod;

[0009] Unlike existing baby strollers, the guardrail assembly includes fixed bases fixed on both sides of the seat, with movable rods movably inserted at the tops of the fixed bases, hinged rods hinged at the tops of the two movable rods, and the fixed bases and movable rods are fixedly connected by clamping members. A traditional U-shaped guardrail is formed by hingedly connecting one hinged rod and two movable rods, and the connection method of the guardrail is improved without changing the protective function of the guardrail, making it easier to open and close the guardrail. It is suitable for both healthy people and people with upper limb disabilities, thereby improving the practicality of the device.

[0010] The seat is provided with an airbag cushion, which can improve the comfort of the baby in the baby stroller. At the same time, the slow-motion airbag compensates for the imbalance of force caused by the loss of upper limbs, ensuring the stability of the child when placed in the stroller.

[0011] Preferably, the bottom end of the movable rod is provided with a plug-in slot which is sleeved on the top of the fixing seat.

[0012] Preferably, the clamping component includes a locking rod that is slidably inserted into the fixed seat through a slide groove, and the bottom of the movable rod is provided with a clamping groove that is connected to the insertion groove. The locking rod is movably inserted into the clamping groove, and an elastic part connected to the locking rod is provided in the slide groove.

[0013] Preferably, the elastic member is specifically a tightening spring, a limiting groove is provided in the slide groove, a limiting slide fixedly connected to the locking rod is slidably sleeved in the limiting groove, and the tightening spring is arranged between the limiting groove and the end of the limiting slide away from the locking rod.

[0014] Preferably, the movable rod and the hinged rod are both covered with protective sleeves; the protective sleeves are made of PU (polyurethane) material, which is soft, wear-resistant, elastic, and has certain shock-absorbing properties.

[0015] Preferably, the moving assembly includes fixed casters symmetrically mounted on the rear side of the frame and movable casters symmetrically mounted on the front side of the frame; the fixed casters can only perform linear motion, and the movable casters can rotate 360° circumferentially, thereby facilitating adjustment of the stroller's forward direction.

[0016] Preferably, a driving motor for driving the shaft of the fixed caster to rotate is fixedly mounted on the frame, and a control button electrically connected to the driving motor is mounted on the handle; the driving motor conveniently drives the shaft of the fixed caster to rotate, thereby reducing the thrust applied by the user, which has the benefit of saving effort; at the same time, the control button can control the start and stop and speed of the driving motor, thereby conveniently controlling the forward and stop of the baby stroller and the movement speed of the baby stroller during walking.

[0017] Preferably, a storage slot is fixedly installed on the frame and below the seat; baby necessities such as milk powder, water and diapers can be placed in the storage slot.

[0018] (3) Beneficial effects

[0019] This application utilizes a hinged rod and two movable rods to hinge together to form a traditional U-shaped guardrail, and then improves the connection method of the guardrail without changing the protective function of the guardrail, making it convenient to open and close the guardrail. It is suitable for healthy people and people with upper limb disabilities, thereby improving the practicality of the device.

[0020] The present application can improve the comfort of the baby in the stroller through the airbag cushion, and at the same time compensate for the force imbalance caused by the loss of upper limbs through the slow-motion airbag, thereby ensuring the stability of the child when placed in the stroller.
