After being taken down from the frame set, a basket can be carried by hand like an ordinary basket, and after being folded, the front feet and the rear feet can be tied to a car seat with a safety belt.

Specifically, the function of movement can be provided after the front feet and the rear feet of the basket are unfolded; after the front feet and the rear feet are unfolded, the lock pins simultaneously penetrate into the first locking holes and the third locking holes, such that relative positions of the front feet and the rear feet are locked; and the lock pins are located on the base, such that relative positions of the front feet, the rear feet, and the base are all locked. In this case, the apparatus can be used as the stroller.

When the apparatus needs to serve as the basket to be fixed to the car seat, the lock pins are taken out from the first locking holes and the third locking holes, and then the front feet and the rear feet are swung; and when the front feet and the rear feet swing to the rear side of the basket set, the lock pins simultaneously penetrate into the second locking holes and the third locking holes, such that the front feet and the rear feet are locked on the rear side of the basket set.

Preferably, the lock pins are connected to first springs, the first springs drive the lock pins to move towards the front feet and the rear feet, the base is provided with a pull handle and steel wires, the pull handle is in sliding fit with the base and is connected to the lock pins through the steel wires, and when the pull handle is pulled, the steel wires drive the lock pins to move away from the front feet and the rear feet.

The lock pins can maintain a stable state of locking the relative positions of the front feet and the rear feet by the first springs, such that the lock pins are prevented from automatically sliding out after penetrating into the first locking holes and the third locking holes, or penetrating into the second locking holes and the fourth locking holes. The pull handle and the steel wires are connected to the lock pins, the pull handle can be pulled to drive the lock pins by using the steel wires to unlock the relative positions of the front feet and the rear feet, and the movement of the lock pins is controlled through the steel wires, such that the pull handle can be arranged more flexibly, making it easier for a user to control the movement of the lock pins.

Preferably, the base is provided with a fastening slot, a double lock catch is provided and includes a hanging and fastening end and an operating end, the double lock catch is hinged to the pull handle, and a first elastic element is arranged between the double lock catch and the pull handle, and drives the hanging and fastening end of the double lock catch to be hung in the fastening slot. Without external interference, the hanging and fastening end of the double lock catch is hung in the fastening slot under the action of the first elastic element. Because the double lock catch is hinged relative to the pull handle, the pull handle will be locked to the base by the double lock catch. When the pull handle needs to be pulled, the operating end of the double lock catch can be pressed to separate the hanging and fastening end from the fastening slot, the locking between the pull handle and the base is released, and then the handle can be pulled to unlock the relative positions of the front feet and the rear feet, which can prevent the pull handle from being pulled due to misoperation, making it safer to use.

Preferably, second springs are arranged between the front feet and the rear feet, and push the front feet and the rear feet to expand. The second springs can provide unfolding force between the front feet and the rear feet, making it more convenient for the front feet and the rear feet to unfold, and providing more stable support for the basket set.

Preferably, arc-shaped slots are provided in end surfaces, close to the rear feet, of the front feet, have the same axis as the rotating shafts, and connect the first locking holes to the second locking holes in series, arc-shaped plates are provided on end surfaces, close to the front feet, of the rear feet in a manner of corresponding to the arc-shaped slots, each of the arc-shaped plates is high in a middle and low on two sides, and the arc-shaped plates are located between the third locking holes and the fourth locking holes.

During rotation of the front feet and the rear feet, the arc-shaped plates slide in the arc-shaped slots. Because the arc-shaped plates are located between the third locking holes and the fourth locking holes, the arc-shaped plates do not interfere with the lock pins when the lock pins penetrate into the third locking holes or the fourth locking holes.

During the process from the state that the lock pins penetrate into the third locking holes or the fourth locking holes to the state that the front feet and the rear feet swing relatively, the lock pins are pulled out from the third locking holes or the fourth locking holes and move back. The arc-shaped plates will pass through the first locking holes or the second locking holes. Because each arc-shaped plate is high in the middle and low on the two sides, the arc-shaped plates will gradually further push the lock pins to move back.

The lock pins are provided with the first elastic elements for forward pushing, such that when the arc-shaped plates pass through the first locking holes or the second locking holes, there will be significant damping, that is, the arc-shaped plates will bring significant damping during the process of switching a relative state of the front feet and the rear feet from one to another, the front feet and the rear feet can be prevented from automatically changing a relative angle, and the front feet and the rear feet remain stable.

Preferably, the basket set includes a basket body, and connecting seats detachably connected to the basket body are upwards arranged on two sides of the base respectively. In this way, more stable support is provided for the basket set.

Preferably, connecting tables and handle connectors are arranged on two sides of the basket body respectively, one end of each of the handle connectors is in running fit with a corresponding one of the connecting tables, and the handle connectors are provided with connecting cavities inserted and matched with handles. Two ends of each handle are inserted into the corresponding handle connector, and the handle connectors are in running fit with the connecting tables, such that the handles can be adjusted in angle relative to the basket body.

Preferably, a plurality of positioning slots are distributed in a side surface of each of the connecting tables, buttons are further provided and hinged relative to the handle connectors, each of the buttons includes a pressing end and a clamping jaw end, second elastic elements are arranged between the buttons and the handle connectors, and each of the second elastic elements pushes the clamping jaw end to be adapted to any one of the positioning slots; and after the pressing ends are pressed, the clamping jaw ends are separated from the positioning slots to unlock relative angles between the handle connectors and the connecting tables, the handle connectors are rotated, and after the clamping jaw ends are adapted to other positioning slots, the relative angles between the handle connectors and the connecting tables are locked again.

The buttons are arranged on the handle connectors, and the clamping jaw ends can be adapted to any positioning slots, such that when the clamping jaw ends are separated from the positioning slots, the handle connectors and the connecting tables can rotate mutually to change an angle, and when the clamping jaw ends are pushed by the second elastic elements to be adapted to the positioning slots, the handle connectors cannot rotate relative to the connecting tables. Specifically, the buttons maintain a trend of adaptively swinging the clamping jaw ends towards the positioning slots through the second elastic elements. Once the handle connectors rotate to move the clamping jaw ends to any positioning slots, the second elastic elements will push the clamping jaw ends of the buttons to be clamped into the positioning slots, the pressing ends of the buttons are pressed to separate the clamping jaw ends from the positioning slots, and then the handle connectors can rotate relative to the basket body.

Preferably, the buttons are provided with hanging tables, lock plates are further provided and hinged to the handle connectors, and third elastic elements are provided between the lock plates and the handle connectors;

hooks are arranged on side edges of front ends of the lock plates, the hooks of the lock plates are pushed by the third elastic elements to be adapted to the hanging tables, and the hooks are configured to limit the pressing ends to be pressed;

front ends of the third elastic elements are pushed by the third elastic elements to swing into the connecting cavities; and when the handles are inserted into the connecting cavities, front ends of the handles push the front ends of the lock plates to swing, such that the hooks are separated from the hanging tables.

The lock plates have two states. In a first state, the handles are not inserted into the connecting cavities of the handle connectors; the hooks of the lock plates hook the hanging tables of the buttons under the action of elastic force of the third elastic elements; the front ends of the lock plates swing and extend into the connecting cavities of the handle connectors; because the hooks of the lock plates hook the hanging tables, the buttons cannot be pressed normally, and the clamping jaw ends cannot be separated from the positioning slots, that is, the handle connectors cannot rotate relative to the connecting tables in the case where the handles are not inserted into the connecting cavities of the handle connectors. In a second state, the handles are inserted into the connecting cavities of the handle connectors; during the process that the handles are inserted into the connecting cavities, the lock plates are pushed to swing, and the front ends of the lock plates are pushed out from the connecting cavities; after the front ends of the lock plates are pushed out, the hooks of the lock plates are separated from the hanging tables, and the buttons can be pressed; and after the buttons are pressed, the clamping jaw ends can be separated from the positioning slots, that is, the handle connectors can rotate relative to the connecting tables in the case where the handles are inserted into the connecting cavities of the handle connectors, thereby preventing the handles from being accidentally touched to swing.

Preferably, clamping slots are provided in side surfaces of the front ends of the handles, guide arc slots are provided in end surfaces of the connecting tables, axes of the guide arc slots are as same as rotation axes of the handle connectors, and each of the guide arc slots includes a clamping section and a shallower separating section;

limit elements and precompressed springs are further provided, the clamping slots and the guide arc slots are located on same sides of the limit elements, the limit elements are provided with clamping ends corresponding to the clamping slots and guide ends corresponding to the guide arc slots and are in sliding fit relative to the handle connectors, and the precompressed springs are arranged between the limit elements and the handle connectors, and push the limit elements to slide towards the clamping slots and the guide arc slots; and

when the guide ends are matched with the clamping sections, the clamping ends are adapted to the clamping slots, and when the guide ends are matched with the separating sections, the clamping ends are separated from the clamping slots.

The limit elements are in sliding fit relative to the handle connectors, and the precompressed springs push the limit elements to slide towards the clamping slots and the guide arc slots. When the guide ends are matched with the clamping sections, because the clamping sections are deeper, the limit elements can be adaptively pushed by the precompressed springs to cause the clamping ends to be adapted to the clamping slots. When the guide ends are matched with the separating sections, the separating sections are shallower and push the guide ends, such that the limit elements can overcome pushing force of the precompressed springs to separate the clamping ends from the clamping slots, that is, the clamping ends and the guide ends get close to or away from the clamping slots and the guide arc slots synchronously. The positions of the guide ends in the guide arc slots are obtained by rotating the handle connectors. When the guide ends rotate to the separating sections, the clamping ends are separated from the clamping slots, and the front ends of the handles are not limited by the clamping ends and can be pulled out from the connecting cavities.

The present disclosure has the following beneficial effects:

With this solution, the apparatus can achieve a three-in-one function of a child seat, a stroller, and a basket, and may arbitrarily switch from the baby stroller to the child safety seat; the functions of the basket and the stroller are achieved through separation and combination of the frame set and the basket set; the apparatus can be combined with a car seat by folding the frame set and adjusting an angle of the handles to achieve the effect of the child safety seat; and the apparatus is stable in overall structure, easy to deform, and very convenient to use.

In this embodiment, there are three positioning slots 206, and the corresponding handles 202 swing to an upper side, a rear side, and a front side of the basket body 201. Certainly, there may be more positioning slots 206 during actual use, such that the handles 202 have more angles.

As shown in FIGS. 11 to 14, the buttons 207 are arranged on the handle connectors 204, and the clamping jaw ends 209 can be adapted to any positioning slots 206, such that when the clamping jaw ends 209 are separated from the positioning slots 206, the handle connectors 204 and the connecting tables 203 can rotate mutually to change an angle, and when the clamping jaw ends 209 are pushed by the second elastic elements 210 to be adapted to the positioning slots 206, the handle connectors 204 cannot rotate relative to the connecting tables 203. Specifically, the buttons 207 maintain a trend of adaptively swinging the clamping jaw ends 209 towards the positioning slots 206 through the second elastic elements 210. Once the handle connectors 204 rotate to move the clamping jaw ends 209 to any positioning slots 206, the second elastic elements 210 will push the clamping jaw ends 209 of the buttons 207 to be clamped into the positioning slots 206, the pressing ends 208 of the buttons 207 are pressed to separate the clamping jaw ends 209 from the positioning slots 206, and then the handle connectors 204 can rotate relative to the basket body 201.

The buttons 207 are provided with hanging tables 213, lock plates 211 are further provided and hinged to the handle connectors 204, and third elastic elements 214 are provided between the lock plates 211 and the handle connectors 204;

hooks 212 are arranged on side edges of front ends of the lock plates 211, the hooks 212 of the lock plates 211 are pushed by the third elastic elements 214 to be adapted to the hanging tables 213, and the hooks 212 are configured to limit the pressing ends 208 to be pressed; and

front ends of the third elastic elements 214 are pushed by the third elastic elements 214 to swing into the connecting cavities 205; and when the handles 202 are inserted into the connecting cavities 205, front ends of the handles 202 push the front ends of the lock plates 211 to swing, such that the hooks 212 are separated from the hanging tables 213.

A side edge of one side, where the corresponding handle 202 enters, of the front end of each third elastic element 214 is set as an inclined surface, such that the front end of the handle 202 can better push the lock plate 211 to swing; a joint between the lock plate 211 and the handle connector 204 is located in a middle of the lock plate 211; the third elastic element 214 is a tension spring connected to a rear end of the lock plate 211; and the tension spring pulls the lock plate 211 to make the front end of the lock plate 211 swing towards one side where the handle 202 is inserted, that is, swing towards one side where the hook 212 is adapted to the hanging table 213.

The lock plates 211 have two states. In a first state, the handles 202 are not inserted into the connecting cavities 205 of the handle connectors 204; the hooks 212 of the lock plates 211 hook the hanging tables 213 of the buttons 207 under the action of elastic force of the third elastic elements 214; the front ends of the lock plates 211 swing and extend into the connecting cavities 205 of the handle connectors 204; because the hooks 212 of the lock plates 211 hook the hanging tables 213, the buttons 207 cannot be pressed normally, and the clamping jaw ends 209 cannot be separated from the positioning slots 206, that is, the handle connectors 204 cannot rotate relative to the connecting tables 203 in the case where the handles 202 are not inserted into the connecting cavities 205 of the handle connectors 204. In a second state, the handles 202 are inserted into the connecting cavities 205 of the handle connectors 204; during the process that the handles 202 are inserted into the connecting cavities 205, the lock plates 211 are pushed to swing, and the front ends of the lock plates 211 are pushed out from the connecting cavities 205; after the front ends of the lock plates 211 are pushed out, the hooks 212 of the lock plates 211 are separated from the hanging tables 213, and the buttons 207 can be pressed; and after the buttons 207 are pressed, the clamping jaw ends 209 can be separated from the positioning slots 206, that is, the handle connectors 204 can rotate relative to the connecting tables 203 in the case where the handles 202 are inserted into the connecting cavities 205 of the handle connectors 204, thereby preventing the handles 202 from being accidentally touched to swing.

Clamping slots 215 are provided in side surfaces of the front ends of the handles 202, guide arc slots 216 are provided in end surfaces of the connecting tables 203, axes of the guide arc slots 216 are as same as rotation axes of the handle connectors 204, and each of the guide arc slots 216 comprises a clamping section 217 and a shallower separating section 218;

limit elements 219 and precompressed springs are further provided, the clamping slots 215 and the guide arc slots 216 are located on same sides of the limit elements 219, and the limit elements 219 are provided with clamping ends 220 corresponding to the clamping slots 215 and guide ends 221 corresponding to the guide arc slots 216 and are in sliding fit relative to the handle connectors 204; and the precompressed springs are arranged between the limit elements 219 and the handle connectors 204, and push the limit elements 219 to slide towards the clamping slots 215 and the guide arc slots 216. Specifically, sliding rods are arranged in the handle connectors 204, and the limit elements 219 are in sliding fit with the sliding rods, such that the limit elements 219 are in sliding fit relative to the handle connectors 204; and the sliding rods away from the clamping ends 220 and the guide ends 221 are provided with the precompressed springs.

When the guide ends 221 are matched with the clamping sections 217, the clamping ends 220 are adapted to the clamping slots 215, and when the guide ends 221 are matched with the separating sections 218, the clamping ends 220 are separated from the clamping slots 215. The clamping ends 220 are clamping hooks adapted to the clamping slots 215, and the guide ends 221 are bosses extending into the guide arc slots 216.

The limit elements 219 are in sliding fit relative to the handle connectors 204, and the precompressed springs push the limit elements 219 to slide towards the clamping slots 215 and the guide arc slots 216. When the guide ends 221 are matched with the clamping sections 217, because the clamping sections 217 are deeper, the limit elements 219 can be adaptively pushed by the precompressed springs to cause the clamping ends 220 to be adapted to the clamping slots 215. When the guide ends 221 are matched with the separating sections 218, the separating sections 218 are shallower and push the guide ends 221, such that the limit elements 219 can overcome pushing force of the precompressed springs to separate the clamping ends 220 from the clamping slots 215, that is, the clamping ends 220 and the guide ends 221 get close to or away from the clamping slots 215 and the guide arc slots 216 synchronously. The positions of the guide ends 221 in the guide arc slots 216 are obtained by rotating the handle connectors 204. When the guide ends 221 rotate to the separating sections 218, the clamping ends 220 are separated from the clamping slots 215, and the front ends of the handles 202 are not limited by the clamping ends 220 and can be pulled out from the connecting cavities 205.

With this solution, the apparatus can achieve a three-in-one function of a child seat, a stroller, and a basket, and may arbitrarily switch from the baby stroller to the child safety seat; the functions of the basket and the stroller are achieved through separation and combination of the frame set 1 and the basket set 2; the apparatus can be combined with a car seat by folding the frame set 1 and adjusting an angle of the handles 202 to achieve the effect of the child safety seat; and the apparatus is stable in overall structure, easy to deform, and very convenient to use.
