[0031] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings, so that the advantages and features of this disclosure can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0032] 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.

[0033] Example 1 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 detachably or non-detachably connected to the base 6.

[0034] The load-bearing device includes a frame 1 and a support frame 2, with the frame 1 rotatably connected to the support frame 2. The load-bearing device also includes a load-bearing mechanism 5 and a linkage mechanism. The load-bearing mechanism 5 includes a load-bearing plate 51 and a fabric sleeve (not shown in the figure) connecting the load-bearing plate 51 and the frame 1. The linkage mechanism is located between the frame 1 and the load-bearing plate 51. The load-bearing device 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 aforementioned linkage mechanism drives the load-bearing plate 51 to adjust its position, thereby ensuring that the position of the load-bearing plate 51 adapts to the load-bearing and protective requirements of the corresponding state after the change of state.

[0035] 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. When the support device is in the first usage state, such as... Figure 1 , Figure 2 As 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 with 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. When the supporting device is in the 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.

[0036] 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 also 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.

[0037] 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 extension direction of the support frame 2, so that the distance between the support plate 51 and the connecting end 2A varies in different usage states. Specifically, in the first usage state, the support plate 51 mainly serves as a seat board to provide hip support for the occupant, while in the second usage state, it serves 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 extension direction 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, the distance between the support plate 51 and the frame 1 increases, and the depth of the lying space formed between them is greater, thereby providing safe and reliable protection for children when lying down.

[0038] The linkage mechanism is movably disposed between the frame 1 and the support plate 51. During the rotation of the frame 1 relative to the support frame 2, the linkage mechanism at least causes the support 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 use state of the support device, the linkage mechanism drives the support plate 51 to move along the length direction of the support frame 2 and switch between the first position and the second position.

[0039] 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 adjusts its usage state, the support plate 51 also adjusts its state accordingly to meet the support for the user in different usage states. For example, in the first usage 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 usage 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.

[0040] In this embodiment, referring to the accompanying drawings, the linkage mechanism includes a linkage rod 31 and a cross brace 4. The first end of the linkage rod 31 is rotatably connected to the frame 1, and the second end of the linkage rod 31 is connected to the cross brace 4. The first end and the second end are opposite ends along the length of the linkage rod 31. 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 31 acts on the cross brace 4, thereby driving the bearing plate 51 to move and adjust its position.

[0041] 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 31 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.

[0042] 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. The sliding member 41 has two parts that are slidably disposed on the two support rods 21. The sliding rod 42 is connected between the two sliding members 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 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.

[0043] Here, a connector 51a is fixedly provided at the bottom of the support plate 51. The longitudinal section of the connector 51a is U-shaped, and the connector 51a has one or more sets spaced apart in the left-right direction. A groove 51b is formed between the support plate 51 and the connector 51a. The slide rod 42 is inserted into the groove 51b, which can both rotate and slide relative to the support plate. In other embodiments, the groove 51b can also be directly provided at the bottom of the support plate 51, so that the groove 51b is provided through in the left-right direction and extends along the length direction of the support plate 51, and the slide rod 42 is inserted into the groove 51b so that it can both slide along the length direction of the support plate 51 and rotate relative to the support plate.

[0044] 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.

[0045] 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.

[0046] 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 for the user's head side.

[0047] In this embodiment, the various parts of the supporting device are specifically arranged as follows: 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.

[0048] The linkage rod 31 has two rods spaced apart in the left-right direction. One end of each linkage rod 31 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 31 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 31 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.

[0049] 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.

[0050] (Not shown in the diagram) The supporting device also has a support structure 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 to each other, and after being connected and fixed, they support the second support plate 53. Especially in the second usage 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.

[0051] (Not shown in the diagram) The supporting device also includes 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, as is available in the prior art, and will not be described in detail here. Positioning the locking structure between the side rails 11 and the support rod 21 makes daily operation easier for the user.

[0052] Of course, in other embodiments, the locking structure can also be set between the slider 41 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.

[0053] 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.

[0054] In some 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 rocking mechanism for driving the support device to swing as a whole, to form a children's rocker for providing comfort to children.

[0055] In other embodiments, the children's product can also be a stroller, with multiple wheel assemblies provided at the bottom of the base 6, and the support device fixed to the base 6 in a detachable or non-detachable manner, providing support for the child to lie down and sit.

[0056] 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.

[0057] Example 2 See Figures 8 to 12 The supporting device 100 shown differs from Embodiment 1 mainly in that the support frame 2 is provided with a seat mounting part, which is detachably fixed to the base of the child product, preferably a stroller. Specifically, in this embodiment, the support frame 2 includes two sets of support rods 21 disposed on the left and right sides, and two sets of mounting brackets 23 disposed on the left and right sides. The mounting brackets 23 are configured to engage with the base of the child product, and the mounting brackets 23 are rotatably arranged relative to the frame 1 with the support rods 21. That is, the mounting brackets 23 constitute the aforementioned seat mounting part. The structure and working principle of the supporting device 100 of this embodiment will be described in detail below with reference to the accompanying drawings.

[0058] See Figures 8 to 12As shown, the supporting device 100 of this embodiment includes a frame 1 and a support frame 2, with the frame 1 rotatably connected to the support frame 2. The supporting device 100 also includes a supporting mechanism 5 and a linkage mechanism. The supporting mechanism 5 includes a supporting plate 51 and a cloth sleeve (not shown in the figure) connecting the supporting plate 51 and the frame 1. The linkage mechanism is disposed between the frame 1 and the supporting plate 51. The supporting device 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 aforementioned linkage mechanism drives the supporting plate 51 to adjust its position, thereby ensuring that the position of the supporting plate 51 adapts to the corresponding state's load-bearing and protective requirements after the change of state.

[0059] In this support device 100, the support frame 2 is configured to be connected to the base of the children's product. The support frame 2 has a connecting end 2A and a mounting end 2B. The connecting end 2A is rotatably connected to the frame 1, and the mounting end 2B is fixedly connected to the base of the children's product. After the support device 100 is installed on the base, the support frame 2 is fixed relative to the base. When the frame 1 is driven to rotate relative to the support frame 2, the usage state of the support device 100 can be changed, making operation more convenient. In this embodiment, the support frame 2 includes two support rods 21 respectively disposed on the left and right sides, and two sets of mounting brackets 23 respectively disposed on the left and right sides. The mounting brackets 23 are connected to the base of the children's product. The two ends of the mounting brackets 23 in the length direction constitute the aforementioned connecting end 2A and mounting end 2B, respectively. The upper ends of the support rods 21 are fixedly disposed to the connecting end 2A, and the two can be synchronously rotated relative to the frame 1.

[0060] In this embodiment, see Figures 8 to 9 As shown, the support device 100 is in its first operating state. The plane of the support plate 51 intersects with the plane of the frame 1. The frame 1 extends vertically and is inclined relative to the horizontal plane, while the support plate 51 extends approximately horizontally. In this first operating state, the support mechanism 5 and the frame 1 form a support space with an overall opening facing forward, which can accommodate an infant or toddler sitting upright. See also... Figures 10 to 12 As shown, the support device 100 is in the second use state. The plane where the support plate 51 is located is parallel or nearly parallel to the plane where the frame 1 is located. The frame 1 is horizontal or nearly horizontal as a whole. The support plate 51 is located below the frame 1. The support mechanism 5 and the frame 1 form a support space with an upward opening. This support space can provide support for infants to lie down or be used to place items.

[0061] When the support device switches between the first and second usage states, the height of the plane containing the support plate 51 also changes. Specifically, when switching from the second to the first usage state, the plane containing the support plate 51 rises. In this embodiment, the support plate 51 is movable at least along the length extension direction of the support rod 21, so that the distance between the support plate 51 and the connecting end 2A is different in different usage states. Specifically, in the first usage state, the support plate 51 mainly serves as a seat board to provide hip support for the occupant, while in the second usage state, it serves as part of a bed board supporting the occupant's body. The support plate 51 moves between the first and second positions along the length extension direction of the support rod 21, 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 use state, the support plate 51 is in the first position, and the distance between the support plate 51 and the frame 1 allows the two to work together to provide a more comfortable sitting space; when the support device is in the second use state, the support plate 51 moves away from the connecting end 2A to the second position, the distance between the support plate 51 and the frame 1 increases, and the depth of the lying space formed between the two is greater, thereby providing safe and reliable protection for children when lying down.

[0062] The linkage mechanism is movably disposed between the frame 1 and the support plate 51. During the rotation of the frame 1 relative to the support frame 2, the linkage mechanism at least causes the support plate 51 to move between the aforementioned first position and second position. That is, during the process of driving the frame 1 to rotate relative to the support frame 2 to adjust the use state of the support device, the linkage mechanism drives the support plate 51 to move along the length direction of the support rod 21 and switch between the first position and the second position.

[0063] 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 adjusts its usage state, the support plate 51 also adjusts its state accordingly to meet the support for the user in different usage states. For example, in the first usage 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 usage 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.

[0064] In this embodiment, the supporting device 100 further includes a bracket 7, with the frame 1 fixedly mounted on the bracket 7. The supporting plate 51 is supported on the bracket 7. When the supporting device 100 transitions from a first usage state to a second usage state, the linkage mechanism drives the supporting plate 51 to move, causing the supporting plate 51 to rotate relative to the bracket 7, thereby adjusting the angle of the supporting plate 51 relative to the frame 1. Specifically, one end of the bracket 7 is connected to the supporting plate 51, which restricts the movement of the supporting plate 51 when the supporting device 100 transitions from the second usage state to the first usage state, allowing the supporting plate 51 to be horizontal or approximately horizontal accordingly.

[0065] Referring to the accompanying drawings, in this embodiment, the linkage mechanism includes a linkage rod 31 and a cross brace 4. The first end of the linkage rod 31 is rotatably connected to the frame 1, and the second end of the linkage rod 31 is connected to the cross brace 4. The first end and the second end are opposite ends along the length of the linkage rod 31. The cross brace 4 is slidably connected to the support rod 21, 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 31 acts on the cross brace 4, thereby driving the bearing plate 51 to move and adjust its position.

[0066] 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 has two parts that are slidably disposed on the two support rods 21 respectively. The sliding rod 42 is connected between the two sliding members 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 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.

[0067] In the first operating state, the sliding rod 42 in the cross brace 4 is connected to the bearing plate 51 at a first connection position. In the second operating state, the sliding rod 42 is connected to the bearing plate 51 at a second connection position. The first and second connection positions are spaced apart along the length 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. As the sliding rod 42 slides between the first and second connection positions along the length of the bearing plate 51, it causes the bearing plate 51 to rotate relative to the bracket 7, thereby changing the angle between the bearing plate 51 and the frame 1, thus adjusting the position of the bearing plate 51 relative to the frame 1.

[0068] In this embodiment, the sliding member 41 is sleeve-shaped and slidably sleeved on the lower part of the support rod 21, so that the lower part of the support rod 21 is always housed in the inner cavity of the sliding member 41. This makes the sliding member 41 and the support rod 21 form a telescopic rod structure when viewed from the outside. When the bearing device 100 switches between the first and second use states, the total length of the sliding member 41 and the support rod 21 changes, and correspondingly, the height of the plane on which the bearing plate 51 is located changes. Specifically, as Figures 8 to 9 As shown, in the first usage state, the sliding rod 42 is connected to the first connection position on the support plate 51. The total length of the sliding member 41 and the support rod 21 is shortened, making one end of the support plate 51 closer to the frame 1. This allows the frame 1 and the support plate 51 to cooperate to form a seat shape, providing a seat for infants and toddlers to sit in. Figures 10 to 12 As shown, in the second usage state, the slide bar 42 is connected to the second connection position on the support plate 51. The total length of the slide bar 41 and the support rod 21 is relatively long, and its length is similar to that of the bracket 7. This makes the support plate 51 and the frame 1 appear to be parallel or nearly parallel to each other. This makes the bearing space formed between the frame 1 and the support plate 51 deeper, so that it can be used for lying down or placing items.

[0069] See Figure 10 As shown, the bottom of the support plate 51 is provided with a guide groove 57 extending along the length direction of the support plate 51. Specifically, a limiting member 56 is fixedly provided at the bottom of the support plate 51. The limiting member 56 extends along the length direction of the support plate 51 and its two ends are respectively fixed to the support plate 51. The guide groove 57 as described above is formed between the limiting member 56 and the support plate 51. The slide rod 42 slides through the guide groove 57. Here, the slide rod 42 can be rotatably connected to the sliding members 41 on both sides around its own axis, or it can be fixedly set on the sliding members 41 and can rotate around its own axis in the guide groove 57. In this way, the cross brace 4 as a whole can rotate and slide relative to the support plate 51.

[0070] In this embodiment, a locking element (not shown in the figure) is also provided between the sliding member 41 and the support rod 21 to lock the two together so that the bearing device 100 is locked in a first use state or a second use state. Specifically, the locking element can be a locking pin movably provided on the sliding member 41 and a locking hole provided on the support rod 21. The locking pin and the locking hole cooperate with each other to lock the sliding member 41 and the support rod 21. Multiple locking holes can also be provided to make the bearing plate 51 at different angles relative to the frame 1, thereby making the bearing device 100 in different bearing states.

[0071] In this embodiment, the frame 1 is frame-shaped and has two rails 11 on the left and right sides. The rails 11 extend in the front-back direction. The bracket 7 and the support frame 2 are both connected to the middle of the rails 11. The bearing plate 51 is located on the front side of the rails 11. Specifically, the bracket 7 includes a support rod 71 on the left and right sides and a connecting rod 72 connecting the support rods 71 ​​on both sides. The other end of the support rod 71 is fixedly connected to the rail 11 on the same side. The bearing plate 51 is supported on the connecting rod 72 and is rotatable relative to the connecting rod 72 around the axis of the connecting rod 72. Here, the rear part of the bearing plate 51 is supported on the connecting rod 72. The bearing mechanism 5 also includes a cloth sleeve (not shown in the figure). By connecting the cloth sleeve to the connecting rod 72, the connecting rod 72 can rotate relative to the bearing plate 51 while providing support for the bearing plate 51. In some other embodiments, the bracket 7 is also provided with a connecting structure (not shown in the figure) for connecting the connecting rod 72 to the support plate 51. The connecting structure can be a flexible belt or other structure, so that the rear position of the support plate 51 is always supported on the connecting rod 72, avoiding its sliding back and forth relative to the connecting rod 72, and also avoiding the support plate 51 tilting upward relative to the connecting rod 72 during the movement, which would affect the position transformation of the support plate 51.

[0072] The bracket 7 is positioned inside the support frame 2 along the left-right direction, and the slide rod 42 is always located in front of the connecting rod 72 on the bearing plate 51. The bearing plate 51 is supported by both the connecting rod 72 and the slide rod 42, resulting in superior load-bearing capacity. On both left and right sides, the upper part of the linkage rod 31 is connected to the surrounding rod 11 at a position behind the position where the bracket 71 is connected to the surrounding rod 11; the lower part of the linkage rod 31 is rotatably connected to the sliding member 41 on the same side. On both left and right sides, the mounting bracket 23 is located outside the support rod 21, and the mounting bracket 23 and the support rod 21 form an acute angle, which makes them staggered and does not affect the installation connection of the mounting bracket 23 on the base of the children's product, nor does it affect the sliding connection between the support rod 21 and the sliding member 41.

[0073] The support mechanism 5 also includes a fourth support plate 55, one end of which is rotatably connected to one end of the support plate 51. Along the length of the support plate 51, the connection position of the slide rod 42 on the support plate 51 is always located on the side of the connecting rod 72 away from the fourth support plate 55. Specifically, the fourth support plate 55 and the support plate 51 can be flexibly connected via a cloth sleeve or rotatably connected via a shaft or other components. In the first usage state, the fourth support plate 55 is set at an angle to the support plate 51, located behind the support plate 51 and used as a backrest, providing back support for infants sitting on the support plate 51. In the second usage state, the fourth support plate 55 and the support plate 51 extend along the same length direction, jointly providing support for a child lying down. The aforementioned state adjustment of the fourth support plate 55 can be achieved by providing an adjustment strap or other components between the frame 1 and the fourth support plate 55.

[0074] See Figure 13 , Figure 14 In a specific embodiment of a children's product having the aforementioned support device 100, the children's product is a stroller with a wheel assembly, specifically a children's stroller. The base of the children's product is a stroller frame 200, on which an interface seat 201 is provided. The mounting bracket 23 in the support frame 2 can be detachably or non-detachably engaged with the interface seat 201, thereby attaching the support device 100 to the stroller frame 200.

[0075] When in use, the stroller rotates the frame 1 relative to the support frame 2, allowing the carrying device 100 to switch between the first and second usage states, thus enabling the stroller to move accordingly. Figure 13 and Figure 14 The system allows users to switch between different states to meet the different needs of infants and toddlers, such as lying down or sitting up, making it convenient for users to take their infants and toddlers out.

[0076] Of course, in other embodiments, children's products with other types of bases can also be grafted and installed with the support device 100 described above.

[0077] 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 installed on the base of different children's products, thereby meeting the different support needs of children.
