[0063] The present invention provides an adapter 3, an adapter device 30, and a child carrier configured with the adapter device 30. Refer to Figure 1 , Figure 1A perspective view of a child carrier according to some embodiments of the present invention is shown. 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 baby stroller. The baby stroller can be a single stroller, a double stroller, etc. The carrier body can be, for example, an infant carrier basket, a stroller seat, etc. The adapter device 30 includes an adapter 3 and a mating component 4, and the adapter 3 is detachably connected to the mating component 4. Hereinafter, while describing the child carrier, the adapter 3 and the adapter device 30 will be described together.

[0064] As Figures 1 to 3 shown, 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 also be configured on the seat frame 12, so that the child carrier can be used by two children (including infants and toddlers) 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 usage requirements of children of different ages and body types in different scenarios. Refer to Figures 1 to 3 , the seat frame 12 is generally 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 away from the push handle 13 (i.e., forward in the front-rear direction) respectively. The two free ends 121 are respectively provided with the mating component 4, and the two mating 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 mating component 4 respectively to detachably connect the carrier body 2 to the frame 1. That is, the carrier body 2 is connected to the two free ends 121 of the seat frame 12 through two adapter devices 30 respectively. In other embodiments not shown, when the carrier body 2 is a stroller seat, the stroller seat can also be directly connected to the mating component 4, and this application does not limit this.

[0065] It should be noted that unless otherwise clearly specified and limited, the orientation terms such as "front", "rear", "upper", "lower", "left", and "right" of the child carrier in each embodiment of the present invention are based on the "front", "rear", "upper", "lower", "left", and "right" orientations of the child carrier traveling normally. In the figure, the arrows L and R schematically show the "left" and "right" directions, and the arrows F and B schematically show the "front" and "rear" directions. These orientation terms are only used to make the description of the embodiments of the present invention clearer and do not improperly limit the protection scope of the present invention.

[0066] As Figure 2 and Figure 4As shown, two adapter devices 30 are symmetrically arranged on the frame body 1, and the structures of the two adapter devices 30 are mirror-symmetrical in the left-right direction. For the convenience of description, the adapter device 30 arranged on the left side of the frame body 1 will be taken as an example for illustration below.

[0067] Referring to Figure 4 and Figure 5 , the mating assembly 4 includes a mating seat 42 and a mating member 41 arranged on the mating seat 42. The mating seat 42 is generally in the shape of a cuboid. The mating seat 42 has a receiving groove 425. The receiving groove 425 has a front side wall 421 and a rear side wall 422 that are generally in the front-rear direction and a left side wall 423 and a right side wall 424 that are generally 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 part of the mating member 41 is received in the receiving groove 425. Specifically, the mating member 41 is, for example, a clamping rod, and both ends of the clamping rod are connected to a pair of side walls of the receiving groove 425. More specifically, one end of the clamping rod is connected to the left side wall 423, the other end of the clamping rod is connected to the right side wall 424, and the mating member 41 extends generally in the left-right direction. Of course, in some other embodiments not shown, the mating member 41 may be located outside the receiving groove 425 of the mating seat 42. In some other embodiments not shown, the mating seat 42 may not be provided, and the mating member 41 may be directly arranged on the frame body 1 (such as the seat frame 12), and the present application does not limit this.

[0068] As Figures 6 to 9 shown, the adapter 3 includes a connecting seat 31, a locking member 32, an operating member 33, a traction assembly 34 and a reset member 35. The connecting seat 31 is generally in the shape of an L. The connecting seat 31 has a first connecting portion 311 and a second connecting portion 312. The first connecting portion 311 extends generally upward in the up-down direction, and the second connecting portion 312 extends generally backward in the front-rear direction. Referring to Figure 1 and Figure 2 , the first connecting portion 311 is adapted to be connected to the vehicle body 2. Specifically, the first connecting portion 311 is adapted to be detachably connected to the side portion of the vehicle body 2.

[0069] As Figures 5 to 7As shown, the second connecting portion 312 of the connecting seat 31 is provided with a clamping groove 317, the opening of the clamping groove 317 faces downward, and the opening of the accommodating groove 425 of the mating seat 42 faces upward. The connecting seat 31 is inserted into the mating seat 42 substantially in the vertical direction. That is to say, the insertion direction of the connecting seat 31 and the mating seat 42 is substantially perpendicular to the normal driving direction of the children's vehicle, so that the separation of the connecting seat 31 and the mating seat 42 can be better restricted during the normal driving of the children's vehicle. In this embodiment, at least a part of the second connecting portion 312 is inserted into the accommodating groove 425, and the clamping groove 317 is clamped with the side wall of the accommodating groove 425. Among them, the clamping groove 317 penetrates through the left and right sides of the connecting seat 31, that is, the clamping groove 317 extends in the substantially left-right direction, and the clamping groove 317 is clamped with the front side wall 421 of the accommodating groove 425. The left and right sides of the second connecting portion 312 are respectively limited by the inner wall of the accommodating groove 425, so as to restrict the movement of the adapter 3 relative to the mating assembly 4 in the left-right direction. One end of the second connecting portion 312 away from the first connecting portion 311 has a limiting convex portion 3121. When the second connecting portion 312 is inserted into the accommodating groove 425, the limiting convex portion 3121 abuts against the end face of the rear side wall 422 of the accommodating groove 425. In this way, the second connecting portion 312 can be more firmly inserted into the accommodating groove 425, reducing the relative shaking between the connecting seat 31 and the mating seat 42.

[0070] In some embodiments, as Figures 8 to 10 shown, 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 an unlocking position. When the locking member 32 is in the locking position, the locking member 32 is locked with the mating member 41. Since the mating assembly 4 is disposed on the frame 1 and the adapter 3 is detachably connected to the vehicle body 2, the vehicle body 2 is fixed to the frame 1 by the cooperation of the adapter 3 and the mating member 41 of the mating assembly 4. When the locking member 32 is in the unlocking position, the locking member 32 is unlocked from the mating member 41 (that is, the locking member 32 is separated from the mating member 41), so as to allow the adapter 3 to be separated from the mating assembly 4, and further allow the vehicle body 2 to be separated from the frame 1. In this way, the vehicle body 2 can be detachably mounted on the frame 1 conveniently by the adapter 3 and the adapter device 30 provided in this embodiment.

[0071] Refer to Figures 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 opening 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 pivoting portion 322. The hook portion 321 is adapted to be engaged with the latch rod 41 to achieve the detachable connection between the adapter 3 and the mating component 4. The pivoting portion 322 is rotatably disposed in the receiving groove 314. When the locking member 32 is in the locking position, at least a part of the hook portion 321 can extend out of the receiving groove 314 to engage with the mating member 41. When the locking member 32 is in the unlocking position, the hook portion 321 retracts into the receiving groove 314 to disengage from the mating member 41. Specifically, the first housing 31a is provided with a convex column portion 318, and the convex column portion 318 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 disposed on the convex column portion 318, and the convex column portion 318 defines the rotation axis of the locking member 32, and this rotation axis extends substantially in the left-right direction. In this embodiment, the second connecting portion 312 is provided with a locking groove 313, and the mating member 41 (i.e., the latch rod) is adapted to be engaged in the locking groove 313. The opening of the locking groove 313 faces downward, the locking groove 313 penetrates through the left and right sides of the connection base 31, and the extending direction of the locking groove 313 is substantially the same as the extending direction of the engaging groove 317. When the locking member 32 is in the locking position, at least a part of the hook portion 321 extends into the locking groove 313 and is engaged with the latch rod to limit the mating member 41 in the locking groove 313, wherein at least a part of the hook portion 321 is located below the latch rod. Through the combined limiting action of the hook portion 321 and the groove wall of the locking groove 313 on the latch rod, the adapter 3 cannot move relative to the mating component 4 in the front-back and up-down directions, so that the vehicle body 2 can be restricted from moving relative to the frame 1 in the front-back and up-down directions. When the locking member 32 is in the unlocking position, the hook portion 321 exits the locking groove 313, thereby allowing the mating member 41 to be separated from the connection base 31. Through the cooperation between the locking groove 313 and the locking member 32, the movement of the mating member 41 in the up-down and front-back directions can be restricted, so that the adapter 3 can be more firmly connected to the mating component 4.

[0072] Continue to refer to Figures 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 to rotate the locking member 32 in the direction of the locking position, and drive 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 the other 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 in the direction of the locking position.

[0073] In some embodiments, as Figures 7 to 9 shown, the operating member 33 is movably disposed on the connecting seat 31 and is drivingly connected to the locking member 32 through the traction assembly 34. Specifically, at least a part of the operating member 33 is received in the receiving 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 the locking position where it can be engaged with the mating member 41, so that the connecting 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 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 where it can be disengaged from the mating member 41, so that the connecting 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 back from the second position to the first position through the traction assembly 34.

[0074] 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 bundle the position of the operating member 33 with the position of the locking member 32 (that is, the setting position of the operating member 33 can be unrestricted by the structure and position of the locking member 32), so that the position of the operating member 33 can be set more flexibly, which is convenient for the user to operate. In this embodiment, the operating member 33 and the locking member 32 are relatively far away from each other. In this way, the length of the turning force arm for rotating the locking member 32 can be adjusted by adjusting the connection position between the traction assembly 34 and the locking member 32, which is beneficial to realizing remote control of the operating member 33 (that is, enabling the locking member 32 to have a longer turning force arm), so that the user can operate the operating member 33 more labor-saving. In addition, in this embodiment, the operating member 33 is connected to the locking member 32 through the traction assembly 34, which can reduce their occupied space, and thus can reduce the overall volume of the adapter 3.

[0075] Refer to Figures 8 to 9, the traction assembly 34 is received in the receiving groove 314 and is 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 Figure 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 (such as a steel wire, a steel cable, a carbon fiber rope, etc.) and a first terminal and a second terminal respectively disposed at both ends of the traction rope. The first terminal serves as the first end 3411, and the second terminal serves as the second end 3412. The traction rope forms the middle portion 3413 of the traction member 341. In some other embodiments 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. The present application does not limit this. 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 extending direction of the traction member 341 and prevent the traction member 341 from winding and knotting in a slack state. In the present embodiment, at least one end of the sheath 342 is connected to the connecting seat 3. Of course, in other embodiments not shown, the sheath 342 may also be sleeved outside the traction member 341 without being connected to the connecting seat 3. The present application does not limit this.

[0076] As Figures 8 to 10 shown, an operation port 315 is provided on the side wall of the receiving groove 314. The operation port 315 is generally located at the first connecting portion 311 of the connecting seat 31, and the operation port 315 communicates with the receiving groove 314. Specifically, the operation port 315 is located on the side of the first connecting portion 311 away from the limiting convex portion 3121 (i.e., the operation port 315 is located on the front side surface of the first connecting portion 311). The operating member 33 is movably inserted at the operation port 315, and the operating member 33 can move in a generally front-rear direction. In the present embodiment, when the operating portion 332 is pressed in the front-rear direction, the operating member 33 moves from the first position to the second position. The operating member 33 has a main body portion 331 and an operating portion 332. The main body portion 331 is received in the receiving groove 314 and is connected to the second end 3412 of the traction member 341. When the operating member 33 is in the first position, at least a part of the operating portion 332 extends out of the receiving groove 314 to facilitate moving the operating member 33 by operating the operating portion 332.

[0077] As Figures 8 to 10As shown, the connecting seat 31 is provided with a protruding portion 316. The protruding portion 316 can be arranged beside the operating member 33, or can be arranged between the operating member 33 and the bottom wall of the receiving groove 314. The middle portion 3413 of the traction member 341 abuts against the protruding portion 316, that is, it is equivalent to the middle portion 3413 of the traction member 341 bypassing the protruding portion 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 protruding portion 316 and is connected to the main body portion 331 of the operating member 33. In this way, the moving direction of the second end 3412 of the traction member 341 can be changed, so that when the operating member 332 moves towards the locking member 32, the traction member 341 is in a tensioned state to drive the locking member 32 to rotate towards the operating member 33.

[0078] In this embodiment, when the operating portion 332 is pressed to move the operating member 33 from the first position to the second position (that is, the operating member 33 is pressed and moved backward), the operating member 33 moves towards the locking member 32, and the distance between the first end 3411 and the second end 3412 decreases. 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 withdrawn (that is, when the operating member 33 is not pressed), the operating member 33 no longer exerts an external force on the traction member 341. 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. During 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.

[0079] Figure 11 The perspective view of the adapter 3 provided according to some other embodiments of the present application is shown. This embodiment is at least different from the above embodiment in the following aspects.

[0080] In another embodiment, as Figures 11 to 13 shown, the operation port 315 is arranged on the second housing 31b, and the operation port 315 communicates with the receiving groove 314. The operating member 33 includes a main body portion 331 and an operating portion 332, and the main body portion 331 is movably arranged in the receiving groove 314. Wherein, a guiding groove 43 is arranged on the bottom wall of the receiving groove 314, and the main body portion 331 is slidably connected with the guiding groove 43. The operating member 33 extends at least partially out of the receiving groove 314 through the operation port 315, so as to facilitate operating 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 in a substantially up and down direction.

[0081] 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 towards 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 restoring 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.

[0082] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.
