[0055] Embodiment 1

[0056] Referring to Figs. 1-7, a child product is shown, which includes a base 6 and a carrying device arranged on the base 6, wherein the carrying device is detachably or non-detachably connected to the base 6.

[0057] The carrying device includes a surrounding frame 1 and a support frame 2, and the surrounding frame 1 is rotatably connected to the support frame 2. The carrying device further includes a carrying mechanism 5 and a linkage mechanism, wherein the carrying mechanism 5 includes a carrying plate 51 and a cloth cover (not shown in the figure) connected between the carrying plate 51 and the surrounding frame 1, and the linkage mechanism is arranged between the surrounding frame 1 and the carrying plate 51. The carrying device has at least a first use state and a second use state, and when the carrying device is switched from the first use state to the second use state, the surrounding frame 1 rotates relative to the support frame 2 and drives the carrying plate 51 to adjust the position through the linkage mechanism, so that the position of the carrying plate 51 after the state change can adapt to the carrying and protection requirements in the corresponding state.

[0058] Specifically, in this embodiment, the first use state is used to provide sitting support, and the second use state is used to provide lying support. When the carrying device is in the first use state, as shown in Figs. 1 and 2, the surrounding frame 1 is arranged obliquely relative to the horizontal plane, and the carrying mechanism 5 and the surrounding frame 1 form a carrying space which is arranged with an overall front opening, at this time, the plane on which the carrying plate 51 is arranged intersects the plane on which the surrounding frame 1 is arranged, and the first included angle between the surrounding frame 1 and the support frame 2 is an acute angle. This state is mainly used for children to sit and use, at this time the carrying device is used as a seat pocket; when the carrying device is in the second use state, as shown in Figs. 6 and 7, the surrounding frame 1 is in a whole horizontal state or a near-horizontal state, and the carrying mechanism 5 and the surrounding frame 1 form a carrying space which is arranged with an overall upward opening, at this time, the plane on which the carrying plate 51 is arranged is parallel to the plane on which the surrounding frame 1 is arranged, and the second included angle between the surrounding frame 1 and the support frame 2 is greater than the first included angle. This state is mainly used for children to lie down, at this time the carrying device is used as a sleeping basket.

[0059] When the carrying device is switched between the above-mentioned first use state and the second use state, the height of the plane on which the carrying plate 51 is arranged also changes, specifically, when switched from the second use state to the first use state, the plane on which the carrying plate 51 is arranged is raised.

[0060] Referring to the drawings, the support frame 2 has a connecting end portion 2A which is rotatably connected to the enclosure 1, and the carrier plate 51 is movably arranged along the length direction of the support frame 2, so that the distance between the carrier plate 51 and the connecting end portion 2A is different in different use states. Specifically, the carrier plate 51 provides a seat plate for supporting the buttocks of a child in a first use state, and provides a part of a bed plate for supporting the body of a child in a second use state. The carrier plate 51 is movable between a first position and a second position along the length direction of the support frame 2, wherein the distance between the second position and the connecting end portion 2A is greater than the distance between the first position and the connecting end portion 2A. When the carrier device is in the first use state, the carrier plate 51 is in the first position, and the distance between the carrier plate 51 and the enclosure 1 is such that the two cooperate to provide a more comfortable space for sitting and standing; when the carrier device is in the second use state, the carrier plate 51 moves away from the connecting end portion 2A to the second position, and the distance between the carrier plate 51 and the enclosure 1 is increased, so that the depth of the lying space formed between the two is greater, thereby providing safe and reliable protection for a child when lying down.

[0061] The linkage mechanism is movably arranged between the enclosure 1 and the carrier plate 51, and during the rotation of the enclosure 1 relative to the support frame 2, the linkage mechanism at least links the carrier plate 51 to move between the first position and the second position.

The carrying device has at least a first use state and a second use state, and when the carrying device is switched from the first use state to the second use state, the frame 1 is rotated relative to the support 2 and drives the carrying plate 51 to adjust the position through the linkage mechanism, so that the position of the carrying plate 51 can adapt to the carrying and protection requirements in the corresponding state after the state is changed.

[0084] In the carrying device 100, the support 2 is configured to be connected to the base of the child product, and the support 2 has a connecting end 2A and a mounting end 2B, the connecting end 2A being rotatably connected to the frame 1, and the mounting end 2B being fixedly connected to the base of the child product. After the carrying device 100 is mounted on the base, the support 2 is fixed relative to the base, and when the frame 1 is driven to rotate relative to the support 2, the use state of the carrying device 100 can be switched, and the operation is more convenient. In the embodiment, the support 2 comprises two support rods 21 arranged on the left and right sides, and two groups of mounting racks 23 arranged on the left and right sides, wherein the base of the child product is connected by the mounting racks 23, and the two ends of the mounting racks 23 in the length direction respectively constitute the connecting end 2A and the mounting end 2B; the upper end of the support rod 21 is fixedly arranged with the connecting end 2A, and the two can be synchronously rotatably arranged relative to the frame 1.

[0085] In the embodiment, referring to Figs. 8-9, the carrying device 100 is in the first use state, and the plane where the carrying plate 51 is located intersects the plane where the frame 1 is located, wherein the frame 1 extends along the up-down direction and is inclined relative to the horizontal plane, and the carrying plate 51 extends along the horizontal direction. In the first use state, the carrying mechanism 5 and the frame 1 form a carrying space which is integrally arranged with the opening facing forward, and the carrying space can be used for the infant to sit and stand. Referring to Figs. 10-12, the carrying device 100 is in the second use state, and the plane where the carrying plate 51 is located is parallel or approximately parallel to the plane where the frame 1 is located, and the frame 1 is in a horizontal state or an approximately horizontal state, and the carrying plate 51 is located below the frame 1. The carrying mechanism 5 and the frame 1 form a carrying space which is integrally arranged with the opening facing upward, and the carrying space can be used for the infant to lie down and support, or for placing articles.

[0086] The height of the plane on which the bearing plate 51 is located also changes when the bearing device is switched between the first and second use states, specifically, the plane on which the bearing plate 51 is located is raised when switched from the second use state to the first use state. In this embodiment, the bearing plate 51 is movably arranged along the length extension direction of the support rod 21, so that the distance between the bearing plate 51 and the connecting end portion 2A is different in different use states. Specifically, the bearing plate 51 mainly provides a seat for supporting the hips of a seated person in the first use state, and is part of a bed plate for supporting the body of a lying person in the second use state. The bearing plate 51 moves between a first position and a second position along the length extension direction of the support rod 21, wherein the distance between the second position and the connecting end portion 2A is greater than the distance between the first position and the connecting end portion 2A. When the bearing device is in the first use state, the bearing plate 51 is in the first position, and the distance between the bearing plate 51 and the surrounding frame 1 is such that the two together provide a more comfortable space for sitting and standing; when the bearing device is in the second use state, the bearing plate 51 moves away from the connecting end portion 2A to the second position, and the distance between the bearing plate 51 and the surrounding frame 1 increases, forming a larger depth of space between the two for lying down, thereby providing safe and reliable protection for children when lying down.

[0087] The linkage mechanism is movably arranged between the surrounding frame 1 and the bearing plate 51, and at least links the movement of the bearing plate 51 between the first and second positions during the rotation of the surrounding frame 1 relative to the support frame 2. That is, during the rotation of the surrounding frame 1 relative to the support frame 2 to adjust the use state of the bearing device, the linkage mechanism drives the bearing plate 51 to move along the length direction of the support rod 21 to switch between the first and second positions.

[0088] In this embodiment, the bearing plate 51 can also be rotatably arranged relative to the support frame 2, so that the angle of the bearing plate 51 relative to the surrounding frame 1 changes, and the bearing plate 51 also adjusts its state accordingly after the bearing device adjusts its use state to meet the support of the user in different use states. For example, in the first use state, the surrounding frame 1 extends obliquely in the up-down direction, and the bearing plate 51 extends obliquely downward from one end to the other end, specifically, it extends downward from front to back along the sitting direction, at this time the bearing plate 51 and the surrounding frame 1 form an acute angle, and the bearing plate 51 can provide support for a child sitting; in the second use state, the bearing plate 51 is switched to a state approximately parallel to the surrounding frame 1, both extend along the horizontal direction and are arranged at a distance along the up-down direction, and the bearing plate 51 provides support for a child lying down, and the surrounding frame 1 and the bearing plate 51 form a lying space for lying support.

[0089] In the embodiment, the bearing device 100 further comprises a bracket 7, the frame 1 is fixedly arranged on the bracket 7, and the bearing plate 51 is supported on the bracket 7. When the bearing device 100 is converted from the first use state to the second use state, the linkage mechanism drives the bearing plate 51 to move so that the bearing plate 51 rotates relative to the bracket 7, thereby enabling the bearing plate 51 to be angularly adjusted relative to the frame 1. In particular, one end of the bracket 7 is connected with the bearing plate 51, and the bearing plate 51 can be limited to move when the bearing device 100 is converted from the second use state to the first use state, so that the bearing plate 51 can be correspondingly in a horizontal state or an approximately horizontal state.

[0090] Referring to the drawings, in the embodiment, the linkage mechanism comprises a linkage rod 31 and a cross strut 4. The first end of the linkage rod 31 is rotatably connected with the frame 1, and the second end of the linkage rod 31 is connected with the cross strut 4. The first end and the second end are two different ends in the length direction of the linkage rod 31. The cross strut 4 is slidably connected with the support rod 21, and the bearing plate 51 is rotatably and slidably connected with the cross strut 4. In the process of rotating the frame 1 relative to the support frame 2, the linkage rod 31 acts on the cross strut 4, thereby driving the bearing plate 51 to move and adjust the position.

[0091] In particular, the cross strut 4 comprises a sliding piece 41 and a sliding rod 42. The sliding rod 42 is fixedly or rotatably connected with the sliding piece 41.

The bearing plate 51 is located between the two support rods 21 in the left-right direction. The bearing plate 51 can be slidably supported on the sliding rod 42 in the length direction of the bearing plate 51 and can be rotatably arranged relative to the sliding rod 42. The sliding rod 42 not only drives the bearing plate 51 to move, but also provides auxiliary support for the bearing plate 51, thereby improving the bearing capacity of the bearing mechanism 5.

[0092] When the bearing device 100 is in the first use state, the sliding rod 42 in the cross strut 4 is connected to a first connection position on the bearing plate 51. When the bearing device 100 is in the second use state, the sliding rod 42 is connected to a second connection position on the bearing plate 51. The first connection position and the second connection position are spaced apart in the length direction of the bearing plate 51, and the distance between the first connection position and the bracket 7 is greater than the distance between the second connection position and the bracket 7. In the process of sliding the sliding rod 42 between the first connection position and the second connection position in the length direction of the bearing plate 51, the sliding rod 42 drives the bearing plate 51 to rotate relative to the bracket 7, so that the angle between the bearing plate 51 and the frame 1 changes, thereby realizing the adjustment of the pose of the bearing plate 51 relative to the frame 1.
