[0048] The present invention provides an adapter 3, an adapter device 30, and a child carrier equipped with the adapter device 30. Referring to FIG. 1, FIG. 1 shows a three-dimensional view of a child carrier provided by an embodiment of the present invention. The child carrier includes a frame 1, a carrier body 2, and an adapter device 30. The carrier body 2 is detachably connected to the frame 1 through the adapter device 30. The child carrier is, for example, a child stroller. The child stroller can be a single stroller, a double stroller, etc. The carrier body can be, for example, an infant carrier, a stroller seat, etc. The adapter device 30 includes an adapter 3 and a matching component 4, and the adapter 3 is detachably connected to the matching component 4. The adapter 3 and the adapter device 30 will be described together with the description of the child carrier below.

[0049] As shown in FIGS. 1 to 3 , the frame 1 includes a wheel frame 11 , a push handle 13 , and a seat frame 12 connected to the wheel frame 11 and the push handle 13 . In some embodiments, in addition to the above-mentioned carrier body 2 , another stroller seat can be configured on the seat frame 12 , so that the child carrier can accommodate two children (including infants and infants) at the same time. Of course, in other embodiments, the child carrier can also be provided with only the carrier body 2 , and by replacing different types of carrier bodies 2 , the child carrier can meet the use needs of children of different ages and different body shapes in different scenarios. Referring to FIGS. 1 to 3 , the seat frame 12 is roughly U-shaped, and the seat frame 12 has two free ends 121 . When the child carrier is in the unfolded state, the two free ends 121 extend in a direction away from the push handle 13 (i.e., forward in the front-rear direction). The two free ends 121 are respectively provided with matching components 4 , and the two matching components 4 are respectively fixedly connected or detachably connected to the wheel frame 11 . The adapter 3 is connected to the carrier body 2 and the matching component 4 respectively, so as to detachably connect the carrier body 2 to the frame body 1. That is, the carrier body 2 is connected to the two free ends 121 of the seat frame 12 respectively through the two adapter devices 30. In other embodiments not shown, when the carrier body 2 is a stroller seat, the stroller seat can also be directly connected to the matching component 4, and the present invention is not limited to this.

[0050] It should be noted that, unless otherwise clearly specified and limited, the directional terms such as "front", "rear", "up", "down", "left", "right" and the like related to the child carrier in each embodiment of the present invention are based on the "front", "rear", "up", "down", "left", and "right" directions of the child carrier in normal travel. In the figure, arrows L and R are used to schematically indicate the "left" and "right" directions, and arrows F and B are used to schematically indicate the "front" and "rear" directions. These directional terms are only used to make the description of the embodiments of the present invention clearer, and are not used to improperly limit the scope of protection of the present invention.

[0051] As shown in Figures 2 and 4, two adapter devices 30 are symmetrically arranged on the frame 1, and the structures of the two adapter devices 30 are mirror-symmetrical in the left-right direction. For ease of description, the adapter device 30 arranged on the left side of the frame 1 is used as an example for description.

[0052] Referring to FIG. 4 and FIG. 5 , the mating assembly 4 includes a mating seat 42 and a mating member 41 disposed on the mating seat 42. The mating seat 42 is substantially in the shape of a rectangular parallelepiped. The mating seat 42 has a containing groove 425. The containing groove 425 has a front side wall 421 and a rear side wall 422 substantially located in the front-rear direction, and a left side wall 423 and a right side wall 424 substantially located in the left-right direction. The rear side wall 422 is connected to the free end 121 of the seat frame 12 and is detachably connected to the wheel frame 11 through a connecting member (such as a screw, a bolt, a rivet, etc.). In this embodiment, at least a portion of the mating member 41 is accommodated in the containing groove 425. Specifically, the mating member 41 is, for example, a clamping rod, and the two ends of the clamping rod are respectively connected to a pair of side walls of the containing groove 425. More specifically, one end of the clamping rod is connected to the left side wall 423, and the other end of the clamping rod is connected to the right side wall 424, and the mating member 41 extends substantially in the left-right direction. Of course, in other embodiments not shown, the matching member 41 may be located outside the containing groove 425 of the matching seat 42. In other embodiments not shown, the matching seat 42 may not be provided, and the matching member 41 may be directly provided on the frame 1 (for example, the seat frame 12), and the present invention is not limited to this.

[0053] As shown in FIGS. 6 to 9 , the adapter 3 includes a connection seat 31, a locking member 32, an operating member 33, a pulling assembly 34 and a reset member 35. The connection seat 31 is generally L-shaped. The connection seat 31 has a first connection portion 311 and a second connection portion 312. The first connection portion 311 extends upward generally in the up-down direction, and the second connection portion 312 extends backward generally in the front-back direction. Referring to FIGS. 1 and 2 , the first connection portion 311 is suitable for connecting with the carrier body 2. Specifically, the first connection portion 311 is suitable for being detachably connected to the side of the carrier body 2. The second connection portion 312 is suitable for being detachably connected to the frame 1.

[0054] As shown in FIGS. 5 to 7 , the second connection portion 312 of the connection seat 31 is provided with a snap-fit groove 317, the opening of the snap-fit groove 317 faces downward, and the opening of the receiving groove 425 of the matching seat 42 faces upward. The connection seat 31 is plugged and matched with the matching seat 42 roughly in the up-down direction. That is, it is equivalent to the plugging direction of the connection seat 31 and the matching seat 42 being roughly perpendicular to the normal driving direction of the child carrier, so that the connection seat 31 and the matching seat 42 can be better restricted from separating during the normal driving of the child carrier. In this embodiment, at least a part of the second connection portion 312 is plugged into the receiving groove 425 and the snap-fit groove 317 is snapped with the side wall of the receiving groove 425. The snap-fit groove 317 can pass through the left and right sides of the connection seat 31, that is, it is equivalent to the snap-fit groove 317 extending roughly in the left-right direction, and the snap-fit groove 317 is snapped with the front side wall 421 of the receiving groove 425. The left and right sides of the second connection part 312 are respectively limited by the inner wall of the containing groove 425, thereby limiting the movement of the adapter 3 relative to the matching component 4 in the left and right directions. The end of the second connection part 312 away from the first connection part 311 has a limiting protrusion 3121. When the second connection part 312 is plugged and matched with the containing groove 425, the limiting protrusion 3121 abuts against the end surface of the rear side wall 422 of the containing groove 425. In this way, the second connection part 312 can be plugged and matched with the containing groove 425 more stably, reducing the relative shaking between the connection seat 31 and the matching seat 42.

[0055] According to one embodiment, as shown in FIGS. 8 to 10 , the locking member 32 is movably disposed on the connecting seat 31. Specifically, the locking member 32 is rotatably disposed on the second connecting portion 312 of the connecting seat 31 and has a locking position and a releasing position. When the locking member 32 is located at the locking position, the locking member 32 is locked with the matching member 41 to connect the adapter 3 with the frame 1. Since the matching component 4 is disposed on the frame 1, the adapter 3 is detachably connected with the carrier body 2. Therefore, the carrier body 2 is fixed on the frame 1 by the matching of the adapter 3 with the matching member 41 of the matching component 4. When the locking member 32 is located at the releasing position, the locking member 32 is unlocked from the matching member 41 (i.e., the locking member 32 is separated from the matching member 41), thereby allowing the adapter 3 to be separated from the matching component 4, so as to allow the adapter 3 to be separated from the frame 1, and further allowing the carrier body 2 to be separated from the frame 1. In this way, the adapter 3 and the adapter device 30 provided in this embodiment can conveniently realize the function of detachably mounting the carrier body 2 on the frame 1.

[0056] Referring to FIGS. 7 to 9 , the connection base 31 includes a first housing 31a and a second housing 31b, and the second housing 31b is detachably connected to the first housing 31a. The first housing 31a is provided with a receiving groove 314, and the second housing 31b covers the notch of the receiving groove 314. The locking member 32 is at least partially received in the receiving groove 314. The locking member 32 has a hook portion 321 and a pivot portion 322. The hook portion 321 is adapted to be engaged with the lever 41 to achieve a detachable connection between the adapter 3 and the mating component 4. The pivot portion 322 is rotatably disposed in the receiving groove 314. When the locking member 32 is located at the locking position, at least a portion of the hook portion 321 can extend out of the receiving groove 314 to be engaged with the mating member 41. When the locking member 32 is located at the unlocking position, the hook portion 321 is retracted into the receiving groove 314 to release the engagement with the mating member 41. Specifically, the first housing 31a is provided with a boss portion 318, which is located in the receiving groove 314 and is fixedly connected or integrally formed with the bottom wall of the receiving groove 314. The pivoting portion 322 of the locking member 32 is rotatably provided on the boss portion 318. The boss portion 318 defines the rotation axis of the locking member 32, which extends substantially in the left-right direction. In this embodiment, the second connecting portion 312 is provided with a locking groove 313, and the matching member 41 (i.e., the clamping rod) is adapted to be clamped in the locking groove 313. The notch of the locking groove 313 faces downward, and the locking groove 313 runs through the left and right sides of the connecting seat 31. The extending direction of the locking groove 313 is substantially the same as the extending direction of the clamping groove 317. When the locking member 32 is located in the locking position, the hook portion 321 at least partially extends into the locking groove 313 and is clamped with the clamping rod to limit the matching member 41 in the locking groove 313, wherein at least a portion of the hook portion 321 is located below the clamping rod. Through the joint limiting effect of the hook portion 321 and the groove wall of the locking groove 313 on the clamp rod, the adapter 3 cannot move relative to the matching component 4 in the front-to-back and up-to-down directions, thereby limiting the movement of the carrier body 2 relative to the frame 1 in the front-to-back and up-to-down directions. When the locking member 32 is in the unlocking position, the hook portion 321 withdraws from the locking groove 313, thereby allowing the matching member 41 to be separated from the connecting seat 31. Through the cooperation between the locking groove 313 and the locking member 32, the movement of the matching member 41 in the up-to-down direction and the front-to-back direction can be limited, thereby more firmly connecting the adapter 3 to the matching component 4.

[0057] Referring to FIGS. 7 to 9 , the reset member 35 is connected to the locking member 32. The reset member 35 is adapted to bias the locking member 32 so that the locking member 32 tends to rotate toward the locking position, and drives the operating member 33 to move from the second position to the first position through the traction assembly 34. In this embodiment, the reset member 35 is, for example, a torsion spring. The reset member 35 is disposed in the receiving groove 314 and sleeved on the convex column portion 318. One pin of the reset member 35 (i.e., the torsion spring) abuts against the locking member 32, and another pin of the reset member 35 (i.e., the torsion spring) abuts against the inner wall of the receiving groove 314. When the locking member 32 is located at the unlocking position, the reset member 35 is in an elastic energy storage state, and the elastic restoring force of the reset member 35 causes the locking member 32 to have a tendency to rotate toward the locking position.

[0058] According to one embodiment, as shown in FIGS. 7 to 9 , the operating member 33 is movably disposed on the connection seat 31 and is drivingly connected to the locking member 32 through the traction assembly 34. Specifically, at least a portion of the operating member 33 is accommodated in the accommodating groove 314. The operating member 33 has a first position and a second position. When the operating member 33 is located at the first position, the locking member 32 is located at a locking position capable of engaging with the mating member 41, so that the connection seat 31 can be fixedly connected to the mating assembly 4; when the operating member 33 moves from the first position to the second position under the action of an external force, the operating member 33 drives the locking member 32 to move from the locking position to the unlocking position through the traction assembly 34; when the operating member 33 moves to the second position, the locking member 32 rotates to the unlocking position capable of releasing the engagement with the mating member 41, so that the connection seat 31 can be separated from the mating assembly 4, and the reset member 35 is in an elastic energy storage state. When no external force is applied to the operating member 33, the locking member 32 rotates from the unlocking position to the locking position under the elastic restoring force of the reset member 35, and drives the operating member 33 to move from the second position to the first position through the traction assembly 34.

[0059] In this embodiment, the operating member 33 is connected to the locking member 32 through the traction assembly 34, and there is no need to bind the position of the operating member 33 to the position of the locking member 32 (that is, the setting position of the operating member 33 may not be restricted by the structure and position of the locking member 32), so that the position of the operating member 33 can be set more flexibly to facilitate the user's operation. In this embodiment, the operating member 33 and the locking member 32 are relatively far apart, so that the length of the turning force arm that rotates the locking member 32 can be adjusted by adjusting the connection position of the traction assembly 34 and the locking member 32, which is conducive to remote control of the operating member 33 (even if the locking member 32 has a longer turning force arm), and the user can control the operating member 33 with less effort. In addition, in this embodiment, the connection of the operating member 33 to the locking member 32 through the traction assembly 34 can reduce its occupied space, thereby reducing the overall volume of the adapter 3.

[0060] Referring to FIGS. 8 and 9 , the traction assembly 34 is accommodated in the accommodation groove 314 and connected between the locking member 32 and the operating member 33. The traction assembly 34 includes a traction member 341 and a sheath 342. One end (i.e., the first end 3411) of the traction member 341 is connected to the locking member 32. Referring to FIG. 10 , the other end (i.e., the second end 3412) of the traction member 341 is connected to the operating member 33. The traction member 341 includes a traction rope (e.g., a steel wire, a steel cable, a carbon fiber rope, etc.) and a first terminal and a second terminal respectively arranged at both ends of the traction rope, the first terminal serving as the first end 3411, the second terminal serving as the second end 3412, and the traction rope forming the middle part 3413 of the traction member 341. According to another embodiment not shown, the traction member 341 may not be provided with the first terminal and / or the second terminal, one end of the traction rope serves as the first end 3411, and / or the other end of the traction rope serves as the second end 3412, and the present invention is not limited thereto. The sheath 342 is sleeved outside the traction member 341, specifically, the sheath 342 is sleeved outside the traction rope of the traction member 341. The sheath 342 is used to guide the extension direction of the traction member 341 and prevent the traction member 341 from being entangled or knotted in a relaxed state. In this embodiment, at least one end of the sheath 342 is connected to the connecting seat 31. Of course, in other embodiments not shown, the sheath 342 can also be sleeved outside the traction member 341 without being connected to the connecting seat 31, and the present invention is not limited to this.

[0061] As shown in FIGS. 8 to 10 , the side wall of the receiving groove 314 is provided with an operating port 315, which is roughly located at the first connecting portion 311 of the connecting seat 31, and the operating port 315 is connected to the receiving groove 314. Specifically, the operating port 315 is located at a side of the first connecting portion 311 away from the limiting protrusion 3121 (that is, the operating port 315 is located at the front side of the first connecting portion 311). The operating member 33 is movably inserted at the operating port 315, and the operating member 33 can move along the roughly front-back direction. In this embodiment, when the operating portion 332 is pressed along the front-back direction, the operating member 33 moves from the first position to the second position. The operating member 33 has a main body 331 and an operating portion 332, and the main body 331 is accommodated in the receiving groove 314 and connected to the second end 3412 of the pulling member 341. When the operating member 33 is located at the first position, at least a part of the operating portion 332 extends out of the receiving groove 314, so that the operating member 33 can be moved by operating the operating portion 332.

[0062] As shown in FIGS. 8 to 10 , the connection seat 31 is provided with a protrusion 316, which can be provided beside the operating member 33 or between the operating member 33 and the bottom wall of the receiving groove 314. The middle part 3413 of the traction member 341 abuts against the protrusion 316, which is equivalent to the middle part 3413 of the traction member 341 bypassing the protrusion 316 to change the movement direction of the traction member 341. In other words, the first end 3411 of the traction member 341 is connected to the locking member 32, and the second end 3412 passes through or bypasses the protrusion 316 and is connected to the main body 331 of the operating member 33. In this way, the movement direction of the second end 3412 of the traction member 341 can be changed, so that when the operating member 332 moves toward the direction close to the locking member 32, the traction member 341 is in a tensioned state and drives the locking member 32 to rotate toward the direction close to the operating member 33.

[0063] In this embodiment, when the operating part 332 is pressed to move the operating member 33 from the first position to the second position (i.e., the operating member 33 is pressed to move backward), the operating member 33 moves in the direction close to the locking member 32, the distance between the first end 3411 and the second end 3412 is reduced, and the traction member 341 is in a tensioned state, thereby driving the locking member 32 to rotate from the locking position to the unlocking position. When the pressing force on the operating member 33 is removed (i.e., when the operating member 33 is not pressed), the operating member 33 no longer exerts an external force on the traction member 341, and the locking member 32 rotates from the unlocking position to the locking position under the elastic restoring force of the reset member 35, and drives the operating member 33 to move forward from the second position and return to the first position through the traction member 341. In this process, the operating member 33 and the locking member 32 switch to positions away from each other, and the distance between the first end 3411 and the second end 3412 increases.

[0064] Fig. 11 is a perspective view of an adapter 3 provided by another embodiment of the present invention. This embodiment is different from the above-mentioned embodiment in at least the following aspects.

[0065] As shown in FIGS. 11 to 13 , the operation port 315 is provided on the second housing 31 b, and the operation port 315 is communicated with the receiving groove 314. The operating member 33 includes a main body 331 and an operating portion 332, and the main body 331 is movably provided in the receiving groove 314. The bottom wall of the receiving groove 314 is provided with a guide groove 43, and the main body 331 is slidably connected to the guide groove 43. The operating member 33 at least partially extends out of the receiving groove 314 through the operation port 315, so as to operate the operating portion 332 to move the operating member 33 between the first position and the second position. In this embodiment, the operating member 33 moves substantially in the up-down direction.

[0066] In this embodiment, when the operating portion 332 of the operating member 33 is pulled upward in the up-down direction, the operating member 33 moves from the first position to the second position, and the traction member 341 is in a tensioned state, thereby driving the locking member 32 to rotate from the locking position to the unlocking position. When the operating member 33 is no longer pulled, the operating member 33 no longer exerts an external force on the traction member 341, and the locking member 32 rotates from the unlocking position to the locking position under the elastic restoring force of the reset member 35, and drives the operating member 33 to move downward from the second position and return to the first position through the traction member 341.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that for those with ordinary knowledge in the field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the claims.
