[0036] The technical solutions in the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art.

[0037] Obviously, the embodiments described in this application are only a part of the embodiments, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0038] The following descriptions of directions such as front, back, left, right, up, and down are defined with reference to the directions observed by the user when using the support device, and are intended only to clearly illustrate the relative positional relationships of the components in the support device.

[0039] See Figures 1 to 7 The children's product shown includes a base 6 and a support device disposed on the base 6, wherein the support device is connected to the base 6 in a detachable or non-detachable manner.

[0040] The supporting device includes a frame 1 and a support frame 2, with the frame 1 rotatably connected to the support frame 2. The supporting device also includes a supporting mechanism 5 and a linkage mechanism. The supporting mechanism 5 includes a supporting plate 51 and a fabric sleeve (not shown in the figure) connecting the supporting plate 51 and the frame 1. The linkage mechanism is located between the frame 1 and the supporting plate 51. This children's product has at least a first usage state and a second usage state. When transitioning from the first usage state to the second usage state, the frame 1 rotates relative to the support frame 2, and the linkage mechanism adjusts the position of the supporting plate 51, thereby ensuring that the position of the supporting plate 51 adapts to the corresponding state's load-bearing and protective requirements.

[0041] Specifically, in this embodiment, the first usage state is used to provide sitting support, and the second usage state is used to provide lying support. The support device is in the first usage state, such as... Figure 1 , Figure 2As shown, the frame 1 is inclined relative to the horizontal plane, and the supporting mechanism 5 and the frame 1 form a forward-opening supporting space. At this time, the plane of the supporting plate 51 intersects the plane of the frame 1, and the frame 1 and the support frame 2 form a first angle, which is an acute angle. In this state, it is mainly used for children to sit upright, and the supporting device is used as a seat. The supporting device is in a second use state, such as... Figure 6 , Figure 7 As shown, the frame 1 is in a horizontal or nearly horizontal state. The supporting mechanism 5 and the frame 1 form a supporting space with an upward opening. At this time, the plane of the supporting plate 51 is parallel to the plane of the frame 1, and the frame 1 and the support frame 2 form a second angle, which is greater than the first angle. In this state, it is mainly used for children to lie down. At this time, the supporting device is used as a sleeping basket.

[0042] When the support device switches between the first and second use states, the height of the plane on which the support plate 51 is located changes. Specifically, when switching from the second use state to the first use state, the plane on which the support plate 51 is located rises.

[0043] Referring to the accompanying drawings, the support frame 2 has a connecting end 2A, which is rotatably connected to the frame 1. The support plate 51 is movable at least along the length of the support frame 2, with varying distances between it and the connecting end 2A in different usage states. Specifically, in the first usage state, the support plate 51 primarily serves as a seat board, providing support for the occupant's buttocks, while in the second usage state, it functions as part of a bed board supporting the occupant's body. The support plate 51 moves between a first position and a second position along the length of the support frame 2, wherein the distance between the second position and the connecting end 2A is greater than the distance between the first position and the connecting end 2A. When the support device is in the first usage state, the support plate 51 is in the first position, and the distance between the support plate 51 and the frame 1 allows them to work together to provide a more comfortable sitting space. When the support device is in the second usage state, the support plate 51 moves away from the connecting end 2A to the second position, increasing the distance between the support plate 51 and the frame 1, resulting in a deeper reclining space and providing reliable protection for children when lying down.

[0044] The linkage mechanism is movably disposed between the frame 1 and the support frame 2. During the rotation of the frame 1 relative to the support frame 2, the linkage mechanism at least causes the bearing plate 51 to move between the first position and the second position. That is, during the process of driving the frame 1 to rotate relative to the support frame 2 to adjust the state of the bearing device, the linkage mechanism drives the bearing plate 51 to move along the length direction of the support frame 2 and switch between the first position and the second position.

[0045] In this embodiment, the support plate 51 can also be rotatably arranged relative to the support frame 2, so that the angle of the support plate 51 relative to the frame 1 changes. Thus, after the support device is adjusted, the support plate 51 also adjusts its state accordingly to meet the support for the user in different states. For example, in the first use state, the frame 1 extends inclinedly in the vertical direction, and the support plate 51 gradually extends downward from one end to the other end, specifically extending downward from front to back along the sitting direction. At this time, the support plate 51 and the frame 1 form an acute angle, and the support plate 51 can provide sitting support for the child. In the second use state, the support plate 51 is converted to a state that is approximately parallel to the frame 1. Both extend horizontally and are spaced apart in the vertical direction. The support plate 51 provides support for the child when lying down, and a lying space for support is formed between the frame 1 and the support plate 51.

[0046] In this embodiment, referring to the accompanying drawings, the linkage mechanism includes a linkage rod 3 and a cross brace 4. The first end of the linkage rod 3 is rotatably connected to the frame 1, and the second end of the linkage rod 3 is connected to the cross brace 4. The first end and the second end are opposite ends along the length of the linkage rod 3. The cross brace 4 is slidably connected to the support frame 2, and the bearing plate 51 is rotatably and slidably connected relative to the cross brace 4. During the rotation of the frame 1 relative to the support frame 2, the linkage rod 3 acts on the cross brace 4, thereby driving the bearing plate 51 to move and adjust its position.

[0047] Specifically, the cross brace 4 includes a sliding member 41 and a sliding rod 42. The sliding rod 42 is fixedly or rotatably connected to the sliding member 41. The sliding member 41 is slidably mounted on the support frame 2 along the length extension direction of the support frame 2. The second end of the linkage rod 3 is rotatably connected to the sliding member 41. The bearing plate 51 is connected to the sliding rod 42 and moves along the length extension direction of the support frame 2 as the sliding member 41 moves on the support frame 2.

[0048] Referring to the accompanying drawings, the support frame 2 includes two support rods 21 spaced apart in the left-right direction. The two support rods 21 are rotatably connected to the frame 1. There are two sliding members 41 that are slidably disposed on the two support rods 21. A sliding rod 42 is connected between the two sliding members 41. The bearing plate 51 is located between the two support rods 21. The bearing plate 51 can be slidably supported on the sliding rod 42 along its own length direction and can be rotatably disposed relative to the sliding rod 42. The sliding rod 42 can not only drive the bearing plate 51 to move, but also provide auxiliary support for the bearing plate 51, thereby improving the bearing capacity of the bearing mechanism 5.

[0049] Here, left and right connecting members 51a are fixedly provided at the bottom of the support plate 51. The longitudinal cross-section of the connecting member 51a is U-shaped. The connecting member 51a has one or more sets arranged at intervals along the left and right directions. A sliding groove 51b is formed between the support plate 51 and the connecting member 51a. The sliding rod 42 is inserted into the sliding groove 51b, which can both rotate and slide relative to each other. In other embodiments, the sliding groove 51b can also be directly provided at the bottom of the support plate 51, so that the sliding groove 51b is provided through in the left and right directions and extends along the length direction of the support plate 51. The sliding rod 42 is inserted into the sliding groove 51b, so that it can both slide along the length direction of the support plate 51 and rotate relative to each other in the sliding groove 51b.

[0050] In this embodiment, the supporting mechanism 5 further includes a first support plate 52, a second support plate 53, and a third support plate 54. One end of the first support plate 52 is rotatably connected to one end of the second support plate 53, and the other end of the first support plate 52 is rotatably connected to the frame 1. The other end of the second support plate 53 is rotatably connected to one end of the supporting plate 51, and one end of the third support plate 54 is rotatably connected to the other end of the supporting plate 51. One-way limiting structures are provided between the first support plate 52 and the second support plate 53, between the second support plate 53 and the supporting plate 51, and between the supporting plate 51 and the third support plate 54 to limit the range of rotation angles between them.

[0051] The load-bearing device is in its first operating state, such as Figures 1 to 3 As shown, the support plate 51 and the second support plate 53 form an angle greater than or equal to 90°. The first support plate 52 and the second support plate 53 extend along the same length direction and are located on one side of the support plate 51. The third support plate 54 extends downward from the other side of the support plate 51. The various parts of the support mechanism 5 cooperate with each other to form a seat for a child to sit on. The first support plate 52 and the second support plate 53 are used to support the user's back and head, the support plate 51 is used to support the user's buttocks and thighs, and the third support plate 54 is used to support the user's calves.

[0052] The support device is in its second operating state, such as Figures 6 to 7 As shown, the second support plate 53, the bearing plate 51 and the third support plate 54 extend along the same length direction, and their extension direction is approximately parallel to the length extension direction of the frame 1 to provide support for the user lying down. The first support plate 52 and the second support plate 53 form an angle greater than or equal to 90° to form protection on the side of the user's head.

[0053] In this embodiment, the various parts of the supporting device are specifically arranged as follows:

[0054] The frame 1 is a closed frame, which can be rectangular or elliptical as shown in this embodiment. The frame 1 has two rails 11 spaced apart in the left and right directions. The support frame 2 is a U-shaped frame with two support rods 21 arranged in the left and right directions. One end of the support rod 21 is rotatably connected to the rail 11 on the corresponding side, and the other end of the two support rods 21 is fixedly provided with a mounting rod 22. The end where the mounting rod 22 is located constitutes the mounting end 2B of the support frame 2. The support frame 2 can be connected to the base 6 by the mounting end 2B. The sliding member 41 is specifically a sliding sleeve, which is slidably sleeved on the support rod 21 on the corresponding side.

[0055] The linkage rod 3 has two rods spaced apart in the left-right direction. One end of each linkage rod 3 is connected to the same-side rail 11, and the other end is connected to the same-side sliding member 41. Here, along the length extension direction of the rail 11, the positions where the connecting end 2A is connected to the rail 11, the positions where the linkage rod 3 is connected to the rail 11, and the positions where the first support plate 52 is connected to the rail 11 are distributed sequentially. The linkage rod 3 also forms a connection and support between the frame 1 and the support frame 2, making the frame 1 and the support frame 2 more stable, thereby enabling the load-bearing device to be stably maintained in the first or second use state.

[0056] The circumferential edge of the cloth cover (not shown in the figure) on the support device is fixed to the frame 1. The support plate 51 of the support mechanism 5 and each support plate are located inside the cloth cover. The cloth cover and the frame 1 together form a support space for sitting or lying down.

[0057] The support device also has a support structure (not shown in the figure) for supporting the second support plate 53. This support structure specifically includes a first strap and a second strap disposed on both sides of the frame 1. The first strap and the second strap are detachably connected and fixed, and after being connected and fixed, they support the second support plate 53. Especially in the second use state, this support structure enables the second support plate 53 to provide better back support for the child. Specifically, at least one of the first strap and the second strap is adjustable in length to accommodate different angle support requirements of the second support plate 53.

[0058] The supporting device is also equipped with a locking structure. In this embodiment, the locking structure is a locking joint located at the rotatable connection between the left and right side rails 11 and the support rod 21, used to lock the two together. The specific structure of the locking joint is not the focus of this application; it can be a locking joint with a locking gear plate, which is not described in detail here. Placing the locking structure between the side rails 11 and the support rod 21 makes it easier for users to operate in daily use.

[0059] Of course, in other embodiments, the locking structure can also be set between the slider 4 and the support frame 2, but a lock hole needs to be set on the support rod 21, and the unlocking structure is relatively complex and the operation is relatively inconvenient.

[0060] In this embodiment, the base 6 specifically includes multiple legs 61 and a connecting seat 62 fixed to the upper end of the legs 61. The connecting seat 62 is provided with a connecting structure (not shown in the figure), and the mounting end 2B of the support frame 2 can be fixedly connected to the base 6 through the connecting structure. Here, the connecting structure is used to detachably engage and fix with the mounting rod 22, so that the mounting end 2B is detachably connected to the base 6. In this way, the carrying device can be installed on the base 6 for use as needed, or it can be removed from the base 6 for use alone, or it can be replaced with other bases for use, such as grafting it onto a stroller or other vehicle for carrying children.

[0061] In other embodiments, the support device may also be non-detachably connected to the base 6, and the base 6 may also be provided with a drive mechanism, such as a swing mechanism for driving the support device to swing as a whole, to provide comfort to the child.

[0062] In summary, the support device provided in this embodiment has a small number of components, a simple structure, and is easy to switch between multiple usage states. The support device can be detachably or non-detachably mounted on the base 6 to form children's products with different functions, thereby meeting the different support needs of children.

[0063] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
