DETAILED DESCRIPTION

[0088] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0089] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0090] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0091] Embodiment 1:

[0092] like Figure 1 As shown, a child mobility system includes a child riding unit 1 and a back carrying unit 6. The child riding unit 1 can be used for a child to ride or lie down, and the back carrying unit 6 can be worn on the user. The child riding unit 1 and the back carrying unit 6 are supported and connected, so that the child riding unit 1 can be suspended around the user under the support of the back carrying unit 6.

[0093] It is understandable that the traditional child carrier is to hold the child close to or against the user's body and hold the child tightly with both hands. The child riding unit 1 of this embodiment can adopt a child seat structure, so that it is convenient for the child to sit; the child riding unit 1 can also adopt a child sleeping basket structure, so that it is convenient for the child to lie down. Both the child seat structure and the child cradle structure can provide a comfortable riding environment for the child.

[0094] At the same time, the child riding unit 1 is suspended and supported by the carrying unit 6, so that the user does not need to support the child riding unit 1 with both hands, thereby appropriately freeing the user's hands. In addition, the child riding unit 1 around the user can also avoid the child riding unit 1 from interfering with the user's walking vision, thereby ensuring the safety of the user's child movement. At the same time, the position of the child riding unit 1 around the user can be adjusted to avoid the user's body being subjected to force in a single direction, thereby improving the user's walking comfort and ensuring the user's physical health.

[0095] In this embodiment, Figure 1As shown, the carrying unit 6 includes a cantilever portion 62 and a wearing portion 61. The wearing portion 61 is used to be worn on the user; the first end of the cantilever portion 62 is connected to the wearing portion 61, and the second end of the cantilever portion 62 can be connected to the child riding unit 1, so that the child riding unit 1 is suspended and connected to the wearing portion 61 through the cantilever portion 62, thereby forming a child basket structure.

[0096] It is understandable that the cantilever portion 62 can be used as a "handle" to form a child basket structure between the child riding unit 1 and the wearing portion 61; that is, the child riding unit 1 is suspended on the wearing portion 61 in an adjustable position. When it is necessary to coax the child riding in the child riding unit 1 to sleep, the user can shake the child riding unit 1 with both hands so that the child riding unit 1 can swing back and forth around the wearing portion 61 through the cantilever portion 62, thereby providing a good coaxing environment for the child to sleep.

[0097] It should be understood that, since the cantilever portion 62 serves as a support for the entire child riding unit 1 , the connection stability between the cantilever portion 62 and the child riding unit 1 needs to be ensured.

[0098] In this embodiment, Figure 1 As shown, the child riding unit 1 is connected to the second end of the cantilever portion 62 via a support member 134 arranged at the bottom; and in order to improve the connection stability between the child riding unit 1 and the cantilever portion 62, the support member 134 and the cantilever portion 62 can be locked by a locking structure when the support member 134 and the cantilever portion 62 are installed.

[0099] In this embodiment, Figures 2 to 4 as well as Figure 7 and Figure 8 As shown, a through hole 1302 is provided at the center of the support member 134, and a locking block 1344 is installed on the side wall of the through hole 1302. The locking structure includes a connecting rod 623 vertically installed at the second end of the cantilever portion 62, and a locking block 1344 installed on the side wall of the through hole 1302; the connecting rod 623 is provided with a locking groove 6230 that can be engaged with the locking block 1344. When the child riding unit 1 and the cantilever portion 62 are installed, the cantilever portion 62 can be plugged into the through hole 1302 through the connecting rod 623, and then the locking block 1344 can be engaged with the locking groove 6230 by moving along the radial direction of the through hole 1302, so that the axial movement tendency of the connecting rod 623 can be restricted to achieve locking of the support member 134 and the cantilever portion 62.

[0100] Specifically, Figures 4 to 8As shown, the support member 134 includes a support sleeve 1343 and a stopper sleeve 1345. The support sleeve 1343 is fixedly arranged, and the through hole 1302 is arranged at the center of the support sleeve 1343. The stopper sleeve 1345 is sleeved on the outside of the support sleeve 1343, and the stopper sleeve 1345 can move along the axial direction of the support sleeve 1343.

[0101] When the connecting rod 623 is plugged into the through hole 1302 and needs to be locked, the stopper 1345 can be moved axially to the first position under the corresponding operation to abut against the locking block 1344, thereby driving the locking block 1344 to lock and engage with the locking groove 6230. When the support member 134 and the cantilever part 62 need to be disassembled, the stopper 1345 can be moved axially to the second position under the corresponding operation to disengage the locking block 1344, thereby the stopper 1345 loses the movement restriction on the locking block 1344, so that when the connecting rod 623 is separated from the through hole 1302, the locking block 1344 will move in a direction away from the locking groove 6230 under the pressure of the locking groove 6230.

[0102] It should be known that there are many ways to install the locking block 1344 on the side of the through hole 1302, including but not limited to the following two.

[0103] Installation method 1: The side of the support sleeve 1343 is provided with an open groove in the vertical direction; the locking block 1344 is rotatably installed on the side of the support sleeve 1343, and can extend into the through hole 1302 along the open groove by rotation. The rotation plane of the locking block 1344 coincides with the vertical plane passing through the axis of the through hole 1302; that is, the locking block 1344 can rotate toward the axis position close to the through hole 1302. Therefore, when the support member 134 is locked with the cantilever part 62, the locking block 1344 can rotate toward the direction close to the connecting rod 623 until the locking block 1344 is engaged with the locking groove 6230, and at this time, the stopper sleeve 1345 limits the movement tendency of the locking block 1344 in the direction away from the connecting rod 623.

[0104] Installation method 2: Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, a sliding hole 1303 is radially arranged on the side of the support sleeve 1343. The locking block 1344 is rod-shaped and slidably mounted in the sliding hole 1303, and the length of the locking block 1344 is greater than the thickness of the support sleeve 1343, that is, the extension length of the sliding hole 1303. Therefore, when the support member 134 and the cantilever portion 62 are locked, the locking block 1344 can slide along the sliding hole 1303 toward the through hole 1302 until the locking block 1344 is engaged with the locking groove 6230 on the connecting rod 623, and at this time, the stopper 1345 limits the movement tendency of the locking block 1344 in the direction away from the connecting rod 623.

[0105] It can be understood that both of the above-mentioned two installation methods can meet the use requirements of this embodiment. In installation method one, the locking block 1344 can be a freely rotatable installation, that is, the rotation of the locking block 1344 depends on the extrusion force of the connecting rod 623 or its own gravity; the locking block 1344 can also be elastically rotatable installation through a torsion spring, that is, the rotation of the locking block 1344 can be automatically performed under the elastic force of the torsion spring. Similarly, in installation method two, the locking block 1344 can be a freely slidable installation, or it can be elastically slidable installation through a spring. The specific installation position and installation method of the torsion spring or spring are conventional settings for those skilled in the art, so they will not be elaborated in detail here. In order to facilitate the description of the subsequent content, the subsequent content is explained by taking the locking block 1344 using the above-mentioned installation method two as an example.

[0106] In this embodiment, Figures 6 to 8 As shown, the inner wall of the stopper sleeve 1345 is provided with a locking area 1306 located at a first position and an unlocking area 1307 located at a second position along the axial direction. The diameter of the locking area 1306 is adapted to the outer diameter of the support sleeve 1343, and the distance from the locking area 1306 to the center of the through hole 1302 is smaller than the distance from the unlocking area 1307 to the center of the through hole 1302. When the support member 134 and the cantilever portion 62 are connected, the locking area 1306 of the stopper sleeve 1344 can abut against the first end of the locking block 1344, so that the second end of the locking block 1344 is engaged with the locking groove 6230 on the connecting rod 623. When the support member 134 needs to be disassembled and separated from the cantilever part 62, the stop sleeve 1345 can be driven as an unlocking member so that the unlocking area 1307 inside the stop sleeve 1345 corresponds to the first end of the locking block 1344; then the locking block 1344 moves along the sliding hole 1303 in the direction away from the connecting rod 623 until the second end of the locking block 1344 disengages from the locking groove 6230 to release the lock between the support member 134 and the cantilever part 62.

[0107] It should be known that in order to ensure the locking stability of the locking block 1344 and the locking groove 6230, the number of locking blocks 1344 can be set to multiple, and the multiple locking blocks 1344 can be arranged at equal intervals along the circumferential direction of the through hole 1302. In order to adapt to the multiple locking blocks 1344, the locking groove 6230 can be arranged circumferentially along the connecting rod 623, and the cross-section of the locking groove 6230 is an arc-shaped structure, so that when the connecting rod 6230 is separated from the through hole 1302, the arc-shaped locking groove 6230 can better generate an extrusion force on the locking block 1344 away from the through hole 1302. At the same time, the locking area 1306 and the unlocking area 1307 both adopt an annular groove structure, and the locking area 1306 and the unlocking area 1307 can be transitioned by an oblique groove.

[0108] For ease of understanding, the specific installation and disassembly process of the support member 134 and the cantilever portion 62 may be described in detail below.

[0109] When it is necessary to install the support member 134 and the cantilever portion 62, as shown in FIG. Figure 8 As shown, the stopper sleeve 1345 can be first moved along the axial direction of the support sleeve 1343 so that the unlocking area 1307 of the stopper sleeve 1345 corresponds to the locking block 1344 installed in the sliding hole 1303 of the support sleeve 1343. Then, the connecting rod 623 installed at the second end of the cantilever portion 62 is inserted into the through hole 1302 from the lower end of the support sleeve 1343 until the locking groove 6230 on the connecting rod 623 is flush with the sliding hole 1303 installed with the locking block 1344. At this time, the second end of the locking block 1344 is located in the sliding hole 1303 and is not engaged with the locking groove 6230.

[0110] Then, if Figure 7 As shown, the stop sleeve 1345 is moved downward along the axial direction of the support sleeve 1343 until the locking area 1306 on the inner side of the stop sleeve 1345 is squeezed and contacted with the first end of the locking block 1344, and then the locking block 1344 slides along the sliding hole 1303 under the squeezing of the stop sleeve 1345 until the second end of the locking block 1344 is engaged with the locking groove 6230; at this time, the axial movement freedom of the locking block 1344 is restricted, so that the axial movement freedom of the connecting rod 623 is also restricted, that is, the connecting rod 623 is locked.

[0111] When the support member 134 and the cantilever portion 62 need to be disassembled, Fig.30As shown, the stopper sleeve 1345 can be moved along the axial direction of the support sleeve 1343 so that the unlocking area 1307 of the stopper sleeve 1345 corresponds to the locking block 1344 installed in the sliding hole 1303 of the support sleeve 1343. Then, the support member 134 is lifted upward, or the cantilever portion 62 is pulled downward, so that the connecting rod 623 slides downward along the through hole 1302, and then the connecting rod 623 squeezes the second end of the locking block 1344 through the arc-shaped locking groove 6230 to drive it to slide along the sliding hole 1303 in a direction away from the connecting rod 623, until the second end of the locking block 1344 is completely separated from the locking groove 6230. Then, the connecting rod 623 is completely separated from the through hole 1302 to complete the disassembly of the support member 134 and the cantilever portion 62.

[0112] In this embodiment, Figure 4 , Figure 7 and Figure 8 As shown, the support member 134 also includes a second support seat 1341; a threaded section is provided at the top of the support sleeve 1343, and the support sleeve 1343 can pass through the center of the entire second support seat 1341, so that the threaded section at the top of the support sleeve 1343 can extend from the top of the second support seat 1341, and then the support sleeve 1343 is fixed to the second support seat 1341 by screwing and tightening the nut 1347 and the threaded section.

[0113] In this embodiment, there are multiple specific installation methods for the stopper sleeve 1345 to achieve axial movement, including but not limited to the following two.

[0114] Installation method 1: The stopper sleeve 1345 is threadedly installed.

[0115] Specifically, the stopper sleeve 1345 is located in the second support seat 1341; the stopper sleeve 1345 is threadedly connected to the inner side of the second support seat 1341 through the outer side wall; or the stopper sleeve 1345 is threadedly connected to the outer side wall of the support sleeve 1343 through the inner side wall. Therefore, when the stopper sleeve 1345 needs to move axially, it only needs to rotate the stopper sleeve 1345 accordingly.

[0116] Installation method two: The stopper sleeve 1345 is axially elastically installed.

[0117] Specifically, Figure 4 , Figure 7 and Figure 8As shown, the stopper sleeve 1345 is located in the second support seat 1341; the stopper sleeve 1345 can be elastically connected to the second support seat 1341 or the support sleeve 1343 through the first elastic member 1346 sleeved on the outside of the support sleeve 1343. That is, one end of the first elastic member 1346 abuts against the end surface of the stopper sleeve 1345, and the other end of the first elastic member 1346 abuts against the second support seat 1341 or the support sleeve 1343. When the support seat 134 is normally connected to the cantilever part 62, the stopper sleeve 1345 can always correspond to the locking block 1344 through the locking area 1306 under the elastic force of the first elastic member 1346, so that the locking block 1344 always locks the connecting rod 623. When the support member 134 and the cantilever part 62 are disassembled, it is necessary to overcome the elastic force of the first elastic member 1346 to drive the stopper sleeve 1345 to move axially.

[0118] It should be known that both of the above two installation methods can meet the use requirements of this embodiment. For the convenience of the subsequent description, the installation method of the stopper 1345 in this embodiment preferably adopts the above installation method 2. Among them, the specific structure of the first elastic member 1346 is well known to those skilled in the art, and common elastic members include springs, springs, disc springs, etc.; in this embodiment, the first elastic member 1346 preferably adopts a spring.

[0119] In this embodiment, Figure 1 and Figure 2 As shown, the cantilever portion 62 includes at least one cantilever assembly 621. If there are multiple cantilever assemblies 621, the multiple cantilever assemblies 621 are connected in sequence in the vertical direction; that is, among adjacent cantilever assemblies 621, the upper cantilever assembly 621 is connected to the top of the lower cantilever assembly 621 through the lower end. When the cantilever portion 62 is installed, the cantilever assembly 621 located at the top can be connected to the bottom of the child riding unit 1 through the top, and the cantilever assembly 621 located at the bottom can be connected to the wearing portion 61 through the lower end. The cantilever assembly 621 can drive the child riding unit 1 to move in multiple directions in the vertical and horizontal directions relative to the wearing portion 61, and then the hanging position of the child riding unit 1 can be arbitrarily adjusted within a certain range according to the user's usage requirements to adapt to different usage environments.

[0120] It should be known that for users of different body types, after they put on the backpack unit 6, the position of the seat portion 11 relative to the user is different. Therefore, in order to facilitate users of different body types or different usage environments, the relative position of the seat portion 11 can be adjusted by the cantilever assembly 621. In addition, when the adjustment range of a single cantilever assembly 621 cannot meet the user's usage requirements, two or more cantilever assemblies 621 can be used in combination to increase the adjustment range of the cantilever portion 62; for example Figure 2As shown, the number of cantilever assemblies 621 is a pair.

[0121] In this embodiment, Fig.15 and Fig.17 As shown, the cantilever assembly 621 includes a first arm 6211 and a second arm 6212. The lower end of the first arm 6211 is hinged to the front end of the second arm 6212 through a hinge, and the hinge direction of the first arm 6211 and the hinge is perpendicular to the hinge direction of the second arm 6212 and the hinge. The cantilever assembly 621 can be connected to the support member 134 at the bottom of the child riding unit 1 through the upper end of the first arm 6211; at the same time, the cantilever assembly 621 can be connected to the wearing part 61 through the rear end of the second arm 6212. When the suspension position of the child riding unit 1 is adjusted, the first arm 6211 can drive the child riding unit 1 to move in the vertical direction by rotating around the hinge, thereby adjusting the height position of the child riding unit 1. The first arm 6211 and the hinge drive the child riding unit 1 to move in the horizontal direction by rotating around the second arm 6212, thereby adjusting the horizontal position of the child riding unit 1.

[0122] It should be understood that if the number of cantilever components 621 exceeds one, the cantilever component 621 located at the top of the cantilever portion 62 can be installed in cooperation with the support member 134 through the upper end of the first arm 6211. At the same time, the cantilever component 621 located at the bottom of the cantilever portion 62 can be installed on the wearable portion 61 through the rear end of the second arm 6212.

[0123] In this embodiment, Fig.15 and Fig.17 As shown, the hinged member is a second hinged seat 627, and the upper end of the first arm 6211 is hingedly mounted with a first hinged seat 622. The first hinged seat 622 and the second hinged seat 627 are both horizontally arranged and parallel to each other, and are hingedly mounted at both ends of the first arm 6211 in the same direction. The first hinged seat 622 is connected to the support member 134 at the bottom of the child riding unit 1 through a fixed connecting rod 623. When the first arm 6211 changes its position in the vertical direction, the first hinged seat 622 and the second hinged seat 627 can always maintain a horizontal state parallel to each other through a balancing structure.

[0124] It should be noted that, when the position of the child riding unit 1 is adjusted, in order to ensure the safety of the child, the sitting posture of the child riding unit 1 cannot change, that is, the child riding unit 1 cannot tilt in the vertical direction. In order to ensure the safety of the child riding unit 1, the first hinge seat 622 and the second hinge seat 627 are connected by a balancing structure in this embodiment, so that when the first arm 6211 drives the child riding unit 1 to change its height at any position in the vertical direction, the first hinge seat 622 and the second hinge seat 627 can always remain horizontal to ensure the stability of the sitting part 11.

[0125] Specifically, there are many specific structures of the equilibrium structure, one of which is Fig.15 and Fig.17 As shown, the cantilever assembly 621 also includes a hinge plate 626 installed inside the first arm 6211; the hinge plate 626 is hinged to the first hinge seat 622 and the second hinge at both ends to form a balanced structure. The hinge position of the corresponding end of the hinge plate 626 is eccentric to the hinge position of the first hinge seat 622 and the second hinge seat 627 at both ends of the first arm 6211, so that the hinge positions at both ends of the hinge plate 626 and the hinge positions at both ends of the first arm 6211 are connected to each other to form a parallelogram structure, as shown in FIG. Fig.17 When the first arm 6211 changes position relative to the second articulated seat 627, the parallelogram structure can force the first articulated seat 622 at the upper end of the first arm 6211 to move synchronously with the first arm 6211 while maintaining parallelism with the second articulated seat 627 at the lower end.

[0126] In this embodiment, Fig.15 and Fig.17 As shown, the cantilever assembly 621 also includes a traction assembly 625 installed in the first arm 6211, and the traction assembly 625 can be elastically deformed; the two ends of the traction assembly 625 are respectively connected with the first hinge seat 622 and the second hinge seat 627. The extension direction of the traction assembly 625 is not parallel to the axis of the first arm 6211, so that the traction assembly 625 and the first arm 6211 can cooperate to form a triangular structure. When the first arm 6211 moves in the vertical direction under the gravity of the child riding unit 1, the shape of the triangular structure changes, and the traction assembly 625 can balance the gravity of the child riding unit 1 through elastic deformation.

[0127] It can be understood that the line connecting the two ends of the first arm 6211 and the hinge points of the first hinge seat 622 and the second hinge seat 627 is defined as the connection L, and the connection L is parallel to the axis of the first arm 6211. Since the extension direction of the traction assembly 625 is not parallel to the axis of the first arm 6211, the extension direction of the traction assembly 625 is also not parallel to the connection L. That is, there is an intersection X between the extension direction of the traction assembly 625 and the extension direction of the connection L; then, in the triangular structure formed by the traction assembly 625 and the first arm 6211, the line connecting the intersection X to the end of the connection L away from the intersection X is the first side of the triangular structure, the line connecting the intersection X to the end of the traction assembly 625 away from the intersection X is the second side of the triangular structure, and the line connecting the connection L and the end of the traction assembly 625 away from the intersection X is the third side of the triangular structure.

[0128] Therefore, when the first arm 6211 rotates, since the first hinge seat 622 and the second hinge seat 627 corresponding to the two ends of the first arm 6211 are kept horizontal by the balance structure, the angles formed by the first arm 6211 and the first hinge seat 622 and the second hinge seat 627 will change, and the shape of the triangular structure will also change accordingly. Since the first arm 6211 and the corresponding first hinge seat 622 and the second hinge seat 627 are all rigid structures, when the shape of the triangular structure changes, it is necessary to compensate by the elastic deformation of the traction assembly 625. As the elastic deformation of the traction assembly 625 increases, the force of the traction assembly 625 to restrict the rotation of the first arm 6211 increases, until the force generated by the deformation of the traction assembly 625 is balanced with the force of the gravity of the child riding unit 1 on the first arm 6211.

[0129] It should also be known that if the intersection X of the extension direction of the traction component 625 and the extension direction of the line L is located at or near the first hinge seat 622, the third side of the triangular structure will be located at the second hinge seat 627. Alternatively, if the intersection X of the extension direction of the traction component 625 and the extension direction of the line L is located at or near the second hinge seat 627, the third side of the triangular structure will be located at the first hinge seat 622. In order to facilitate the installation of the subsequent adjustment component and the description of the content, the third side of the triangular structure is located at the second hinge seat 627 as an example for description.

[0130] In this embodiment, based on the third side of the triangular structure being located at the second hinge seat 627, there are multiple ways to install the traction assembly 625, one of which is preferably as follows: Fig.17As shown, the upper end of the traction assembly 625 is installed at the hinge position between the first hinge seat 622 and the first arm 6211; the installation position of the lower end of the traction assembly 625 deviates from the hinge position between the first arm 6211 and the second hinge seat 627. Then the connecting line L is the first side of the triangle structure, the traction assembly 625 is the second side of the triangle structure, and the connecting line between the hinge position of the lower end of the first arm 6211 and the second hinge seat 627 and the installation position of the lower end of the traction assembly 625 is the third side of the triangle structure.

[0131] Therefore, when the first arm 6211 rotates downward in the vertical direction, the angle between the first arm 6211 and the second hinge seat 627 increases, and the angle between the first side and the third side of the triangular structure will also increase. Since the lengths of the first side and the third side of the triangular structure cannot be changed, the second side, i.e., the traction assembly 625, needs to be increased in length to adapt to the shape change of the triangular structure, and then the traction assembly 625 balances the gravity of the child riding unit 1 on the first arm 6211 through elastic deformation.

[0132] In this embodiment, Figures 15 to 17 As shown, the traction assembly 625 includes a third elastic member 6251 and an adjustment assembly. The upper end of the third elastic member 6251 is connected to the upper hinge position of the first arm 6211; the adjustment assembly is installed on the lower side of the second hinge seat 627, and the adjustment assembly is connected to the lower end of the third elastic member 6251. When the first arm 6211 moves in the vertical direction, the traction assembly 625 can balance the gravity of the child riding unit 1 through the elastic deformation of the third elastic member 6251; at the same time, the adjustment assembly can also adjust the deformation degree of the third elastic member 6251, thereby changing the suspension height of the cantilever part 62 to the child riding unit 1.

[0133] It should be known that the specific structure of the third elastic member 6251 is well known to those skilled in the art. In this embodiment, the third elastic member 6251 is preferably a spring, and the elastic coefficient of the third elastic member 6251 is relatively large to meet the weight requirements of the child. When the elastic coefficient of the third elastic member 6251 is determined, the degree of elastic deformation of the third elastic member 6251 when the child sits on the child seating unit 1 is determined. The angle at which the first arm 6211 is deflected is a reflection of the degree of elastic deformation of the third elastic member 6251.

[0134] Depending on the height and usage habits of the user, the relative height of the child riding unit 1 may need to be adjusted, that is, the descending height of the first arm 6211 needs to be adjusted. At this time, the deformation degree of the third elastic member 6251 can be changed by adjusting the assembly; since the weight of the child riding unit 1 does not change, the total deformation degree of the third elastic member 6251 will not change, and the first arm 6211 can be adjusted in height direction under the elastic force of the third elastic member 6251. Of course, it is also possible to adapt to child riding units 1 of different weights while keeping the height of the first arm 6211 unchanged.

[0135] At the same time, in order to facilitate adjustment, the adjustment component is arranged on the second hinge seat 627 corresponding to the lower end of the first arm 6211, which can facilitate the user to operate. In addition, the movement state of the second hinge seat 627 corresponding to the lower end of the first arm 6211 is independent of the movement state of the first arm 6211, so that the position of the adjustment component will not change with the position change of the first arm 6211, which can further facilitate the user to operate.

[0136] For ease of understanding, the height adjustment process of the child seating unit 1 by the adjustment component may be analyzed and described below through parameters.

[0137] Assume that the angle between the first arm 6211 and the horizontal direction when the gravity of the child riding unit 1 remains unchanged is α, and the deformation length of the third elastic member 6251 as the corresponding hypotenuse of the angle α compared with the initial position is a. Taking the increase in the height of the child riding unit 1 as an example, the change in the deformation length of the third elastic member 6251 caused by the adjustment component is b. At this time, if the position of the first arm 6211 remains unchanged, the total deformation length of the third elastic member 6251 is a+b; the corresponding elastic force under this deformation length is greater than the gravity of the child riding unit 1. That is, the first arm 6211 needs to rotate upward to reduce the value of the angle α, and then the deformation length of the third elastic member 6251 as the corresponding hypotenuse of the angle α will be shortened by b, so that the total deformation length of the third elastic member 6251 is still the length a that balances the gravity of the child riding unit 1. It should be known that the above analysis process ignores the influence of the first arm 6211 on the force process due to the angle change.

[0138] In this embodiment, there are many specific structures of the adjustment component, one of which is as follows: Fig.16 and Fig.18As shown, the adjustment assembly includes a moving rod 6255 and an adjustment seat 6256. The moving rod 6255 is vertically slidably installed on the lower side of the second hinge seat 627 and connected to the lower end of the third elastic member 6251; the adjustment seat 6256 is rotatably installed on the lower side of the second hinge seat 627 and is threadedly connected to the moving rod 6255. When it is necessary to change the suspension height of the child riding unit 1, by screwing the part of the adjustment seat 6256 extending out of the second hinge seat 627, the moving rod 6255 can be driven to move axially according to the threaded screwing between the moving rod 6255 and the adjustment seat 6256, thereby adjusting the initial deformation length of the third elastic member 6251.

[0139] It is understandable that the adjustment of the deformation degree of the third elastic member 6251 by the adjustment component can be regarded as the adjustment of the initial deformation length of the third elastic member 6251 when the first arm 6211 is not deflected. That is, when the total deformation length of the third elastic member 6251 remains unchanged, the longer the initial deformation length is, the smaller the angle at which the first arm 6211 can be deflected is.

[0140] It is also understandable that, since the adjusting seat 6256 and the moving rod 6255 are threadedly matched, the rotation of the moving rod 6255 in the circumferential direction must be limited to ensure that the rotation of the adjusting seat 6256 can only drive the moving rod 6255 to move axially. There are many ways to enable the moving rod 6255 to move only axially, and the common ones include the upper end of the moving rod 6255 being spline-connected to the second hinge seat 627, or the cross-sectional shape of the moving rod 6255 being non-circular.

[0141] In this embodiment, Figures 16 to 18 As shown, a guide roller 6257 is rotatably mounted on the second hinge seat 627; the length of the third elastic member 6251 is less than the length of the first arm 6211. The traction assembly 625 also includes a traction rope 6254, the upper end of which is connected to the lower end of the third elastic member 6251, and the lower end of which is connected to the adjustment assembly after passing through the guide roller 6257, so that when the first arm 6211 moves in the vertical direction, the extension direction of the traction rope 6254 between the guide roller 6257 and the adjustment assembly and the angle between the adjustment assembly remain unchanged; thereby, the interference wear between the traction rope 6254 and the installation position of the moving rod 6255 can be effectively reduced, so as to increase the service life of the traction rope 6255.

[0142] It should be known that if the third elastic member 6251 is directly connected to the moving rod 6255, when the first arm 6211 rotates, the third elastic member 6251 may interfere with the second hinge seat 627 due to its larger circumferential size. However, by providing a traction rope 6254 to connect the third elastic member 6251 to the moving rod 6255, the interference between the third elastic member 6251 and the second hinge seat 627 can be avoided.

[0143] Meanwhile, if the guide roller 6257 is not provided, when the first arm 6211 rotates, the connection position of the traction rope 6254 and the moving rod 6255 will bend because the position of the moving rod 6255 remains unchanged, which will aggravate the wear of the traction rope 6254 in the long run. However, after the guide roller 6257 is provided in the present embodiment, when the first arm 6211 rotates, the traction rope 6254 between the guide roller 6257 and the moving rod 6255 can remain parallel or slightly inclined to the axis of the moving rod 6255, thereby effectively avoiding the bending of the connection position of the traction rope 6254 and the moving rod 6255.

[0144] In this embodiment, Figures 16 to 18 As shown, the traction assembly 625 also includes an upper connection seat 6252 and a lower connection seat 6253. The upper connection seat 6252 is fixedly mounted on the upper end of the third elastic member 6251, so that the third elastic member 6251 is rotatably connected to the upper hinge position of the first arm 6211 through the upper connection seat 6252. The lower connection seat 6253 is fixedly mounted on the lower end of the third elastic member 6251, so that the third elastic member 6251 is connected to the traction rope 6254 through the lower connection seat 6253. The upper connection seat 6252 and the lower connection seat 6253 can effectively reduce the difficulty of installation and the degree of wear of the third elastic member 6251.

[0145] For ease of understanding, the specific working process of the traction assembly 625 is described in detail below. The swing of the first arm 6211 in the vertical plane can be regarded as the rotation of the first arm 6211 around the hinge seat at one end; take the rotation of the first arm 6211 around the first hinge seat 622 at the upper end as an example. That is, the first hinge seat 622 at the upper end of the first arm 6211 remains horizontal, and in the process of the first arm 6211 rotating around the first hinge seat 622 at the upper end, the hinge plate 626 can rotate synchronously with the first arm 6211. Since the first hinge seat 622 at the upper end of the first arm 6211 is considered to be horizontal, the hinge plate 626 can drive the second hinge seat 627 moving with the lower end of the first arm 6211 to rotate relatively around the lower end of the first arm 6211 by rotating the upper end around the hinge seat 622, so that the first hinge seat 622 and the second hinge seat 627 corresponding to the upper and lower ends of the first arm 6211 respectively maintain a parallel horizontal state. Of course, the swing of the first arm 6211 can also be regarded as a rotation around the corresponding second hinge seat 627 at the lower end, and the specific process is the same as the above process.

[0146] During the swinging of the first arm 6211, it can be known from the above contents that the angle between the second hinge seat 627 corresponding to the lower end of the first arm 6211 and the first arm 6211 will change, and then the shape of the triangle structure formed by the first arm 6211, the traction assembly 625 and the guide roller 6257 will change. Since the adjustment assembly and the guide roller 6257 are both installed on the second hinge seat 627 corresponding to the lower end of the first arm 6211, the position between the guide roller 6257 and the adjustment assembly will not change with the swinging of the first arm 6211; at the same time, the traction rope 6254 is generally assumed not to be elastically deformed, so the change in the length of the triangle formed by the traction assembly 625 can be specifically the change in the angle of the traction rope 6254 around the guide roller 6257 and the change in the length of the third elastic member 6251. Then, the elastic force generated by the elastic deformation of the third elastic member 6251 can balance the driving force that causes the first arm 6211 to swing.

[0147] When the swing amplitude of the first arm 6211 needs to be adjusted, the adjusting seat 6256 can be rotated to drive the moving rod 6255 to move axially, thereby changing the length of the corresponding traction rope 6254 between the guide roller 6257 and the adjusting assembly. Since the total length of the traction rope 6254 remains unchanged, the length of the corresponding traction rope 6254 between the guide roller 6257 and the third elastic member 6251 also changes, and the third elastic member 6251 needs to compensate for the change in the length of the corresponding traction rope 6254 between the guide roller 6257 and the third elastic member 6251 through its own elastic deformation; that is, the elastic force of the third elastic member 6251 changes, and when the third elastic member 6251 balances the driving force of the first arm 6211 to swing, the corresponding swing amplitude of the first arm 6211 will change.

[0148] In summary, when the first arm 6211 swings and adjusts the swing range, the first hinge seat 622 and the second hinge seat 627 corresponding to the upper and lower ends of the first arm 6211 only change the vertical height difference. Therefore, the adjustment component is arranged at the second hinge seat 627 corresponding to the lower end of the first arm 6211. On the one hand, it can ensure that the direction of the adjustment component will not change with the swing of the first arm 6211, and on the other hand, the adjustment component can be closer to the user for easy operation.

[0149] In this embodiment, Fig.19 and Fig. 20 As shown, one side of the wearable portion 61 is connected to the first end of the cantilever portion 62 through a reset component; the reset component always generates a force on the first end of the cantilever portion 62 to approach the wearable portion 61, so that the first end of the cantilever portion 62 maintains a fit with the wearable portion 61 under the drive of the reset component, thereby better transmitting the gravity of the child riding unit 1 carried by the cantilever portion 62 to the user.

[0150] It should be known that, according to the general usage habits of the user, the cantilever portion 62 can be installed on the right side of the wearable portion 61 through the reset component, or it can be installed on the left side of the wearable portion 61. For the convenience of the subsequent description, the subsequent content is described by taking the cantilever portion 62 installed on the right side of the wearable portion 61 as an example.

[0151] If there is no reset component between the cantilever portion 62 and the wearable portion 61, or the reset component has no reset force; then during use, on the one hand, the user may need to hold the cantilever portion 62 by himself to prevent the cantilever portion 62 from shifting; on the other hand, when the cantilever portion 62 deviates to the right, the bearing force of the cantilever portion 62 will be transmitted to the wearable portion 61 through the reset component; since the deviation direction of the cantilever portion 62 is away from the user, the force arm of the bearing moment formed by the bearing force of the cantilever portion 62 on the user will increase, thereby increasing the bearing moment to force the user to tilt to the right, and long-term use will lead to a poor user experience.

[0152] In this embodiment, the restoring force of the restoring assembly can drive the first end of the cantilever portion 62 to automatically approach the wearable portion 61, thereby eliminating the need for the user to hold the cantilever portion 62. In addition, the approach of the cantilever portion 62 can also shorten the value of the bearing moment, thereby providing the user with a better use experience.

[0153] In this embodiment, Fig.19 and Fig. 20 As shown, the reset assembly includes a fourth elastic member 615 and a support plate 614; the first end of the support plate 614 is elastically hinged to the wearable portion 61 through the fourth elastic member 615, and the hinge rotation direction of the support plate 614 is parallel to the horizontal plane. The cantilever portion 62 can be mounted on the second end of the support plate 614 through the first end, and then under the elastic force of the fourth elastic member 615, the support plate 614 always drives the first end of the cantilever portion 62 to approach and fit the wearable portion 61.

[0154] It should be known that the specific structure of the fourth elastic member 615 is a well-known technology to those skilled in the art; in this embodiment, the fourth elastic member 615 is preferably a torsion spring.

[0155] In this embodiment, Fig.19 and Fig. 20 As shown, the first end of the support plate 614 is hinged to the rear part of one side of the wearable portion 61, and the second end of the support plate 614 is connected to the second end of the cantilever portion 62 along the middle or front part of one side of the wearable portion 61. When the cantilever portion 62 is in use, the bearing force of the cantilever portion 62 can be transmitted to the rear part of one side of the wearable portion 61 through the support plate 614, and then the overall trend of the bearing moment of the cantilever portion 62 tends to be forward.

[0156] It can be understood that if the first end of the support plate 614 is connected to the middle of one side of the wearable portion 61, the overall trend of the bearing torque generated by the gravity of the sitting portion 11 of the cantilever portion 62 tends to the right side of the user; which will cause the user to have a tendency to tilt to the right. When the user supports the sitting portion 11 with a child for walking through the backpack unit 6, the user's travel direction is front and back, and the tendency to tilt to the right will interfere with the user's normal walking. Since the walking stability of a person in the forward direction is better than the lateral direction; therefore, in this embodiment, the first end of the support plate 614 is connected to the rear of one side of the wearable portion 61, and the second end of the support plate 614 is extended forward to the middle or front end of the wearable portion 61, preferably the front end; then the overall trend of the bearing capacity of the cantilever portion 62 is forward, which can effectively improve the walking stability of the user relative to the side installation of the support plate 614.

[0157] In this embodiment, Fig.19 and Fig. 20 As shown, the reset assembly also includes a mounting seat 616, and the second end of the support plate 614 is connected to the cantilever portion 62 through the mounting seat 616. The mounting seat 616 can appropriately extend the support distance between the cantilever portion 62 and the wearable portion 61, and can also facilitate the installation between the cantilever portion 62 and the wearable portion 61.

[0158] In this embodiment, Fig.19 As shown, the wearing part 61 includes a shoulder strap part 611 and a waist belt part 612; when the user wears the wearing part 61, the shoulder strap part 611 can be worn on the user's shoulders, and the waist belt part 612 can be worn on the user's waist, and the shoulder strap part 611 and the waist belt part 612 can be connected by an adjustment structure, and the connection height between the shoulder strap part 611 and the waist belt part 612 can be adjusted by the adjustment structure, so as to adapt to users of different body shapes. The cantilever part 62 can be installed on the waist belt part 612 through a reset assembly, so that the cantilever part 62 can be better supported by the user's waist.

[0159] In this embodiment, Fig.19As shown, the adjustment structure includes an upper mounting frame 6111, a lower mounting frame 6121 and an adjustment plate 613. The upper mounting frame 6111 is fixedly arranged at the rear side of the shoulder strap portion 611; the lower mounting frame 6121 is fixedly arranged at the rear side of the waist belt portion 612; the adjustment plate 613 can pass through the upper mounting frame 6111 and the lower mounting frame 6121, and the upper mounting frame 6111 and the lower mounting frame 6121 are both pressed and fixed by fasteners 136 to adjust the height between the shoulder strap portion 611 and the waist belt portion 612. When it is necessary to adjust the height between the shoulder strap portion 611 and the waist belt portion 612, the fasteners 136 on the upper mounting frame 6111 can be preferably rotated to loosen the pressing of the adjustment plate 613; then the shoulder strap portion 611 is relatively slid along the adjustment plate 613 to adjust the height of the shoulder strap portion 611. After the adjustment is completed, the adjustment plate 613 can be pressed again by the fasteners 136 on the upper mounting frame 6111.

[0160] It should be noted that when adjusting the height between the back strap portion 611 and the waist belt portion 612, the position of the waist belt portion 612 relative to the adjustment plate 613 can also be adjusted; however, considering that adjusting the waist belt portion 612 will cause the adjustment portion 613 to extend downward from the waist belt portion 612, it may affect the user's normal walking. Therefore, when adjusting the height of the wearing portion 61, it is preferred to adjust the back strap portion 611.

[0161] Embodiment 2:

[0162] Compared with the first embodiment, the difference of this embodiment is that: Fig.10 , Fig.13 and Fig.14 As shown, the locking structure includes a locking assembly 624; the locking assembly 624 is hingedly mounted on one side of the second end of the cantilever portion 62, and the locking assembly 624 can be mutually buckled with the other side of the second end of the cantilever portion 62 to form a locking cavity 6200. When the support member 134 and the cantilever portion 62 are installed, the support member 134 can be plugged and tightly held with the locking cavity 6200 through the connecting portion 1305. When the support member 134 and the cantilever portion 62 need to be disassembled, the buckling of the locking assembly 624 and the cantilever portion 62 can be released to open the locking cavity 6200.

[0163] It is understandable that the cross-sectional shape of the lock cavity 6200 is adapted to the cross-sectional shape of the connection portion 1305 used for embracing and locking by the support member 134. There are many specific cross-sectional shapes, such as circular, rectangular or polygonal, etc. It is only necessary to ensure that the lock cavity 6200 can stably embracing and locking the connection portion 1305. In order to facilitate the description of the subsequent content, the cross-sectional shape of the lock cavity 6200 and the connection portion 1305 in this embodiment is preferably circular.

[0164] It can also be understood that the second end of the cantilever portion 62 can cooperate with the locking assembly 624 through the first hinge seat 622 to form a locking cavity 6200.

[0165] In this embodiment, Fig. 9 and Fig.32 As shown, the support member 134 includes a second support seat 1341 and a support sleeve 1343. The fixing method of the support sleeve 1343 and the second support seat 1341 is the same as that of the first embodiment; the lower part of the support sleeve 1343 extending out of the bottom end of the second support seat 1341 is provided with a connecting portion 1305, and both ends of the connecting portion 1305 are provided with blocks. Then the cantilever portion 62 holds and locks the connecting portion 1305 in the area between the two blocks through the locking cavity 6200.

[0166] In this embodiment, Figures 10 to 14 As shown, the first hinge seat 622 is provided with a first arc groove 6221 and a locking hole 6222 on one side of the extension direction; the locking hole 6222 is located at the first end of the first arc groove 6221. The lock assembly 624 includes a lock body 6241 and a locking tongue 6243. The lock body 6241 is provided with a second arc groove 6201, and the lock body 6241 can be hinged to the second end of the first arc groove 6221 through the first end; the locking tongue 6243 is installed at the second end of the lock body 6241. When installing the support member 134 and the cantilever part 62, the first arc groove 6221 can be aligned with the connection part 1305; then the lock body 6241 can be rotated around the second end of the first arc groove 6221 until the lock tongue 6243 extends into the locking hole 6222 and engages, and then the first arc groove 6221 can be matched with the second arc groove 6201 to form the lock cavity 6200, and the connection part 1305 is tightly locked. When the support member 134 needs to be disassembled from the cantilever part 62, the engagement between the lock tongue 6243 and the locking hole 6222 can be released, so that the lock body 6241 can be rotated around the installation position to open the lock cavity 6200.

[0167] In this embodiment, a locking portion 6223 is provided on one side of the locking hole 6222, and the locking tongue 6243 can be engaged with the locking portion 6223. There are many specific engagement structures between the locking tongue 6243 and the locking portion 6223, including but not limited to the following two structures.

[0168] Snap-fit ​​structure 1: Figures 11 to 14As shown, a locking portion 6223 is fixedly provided on one side of the locking hole 6222; a locking tongue 6243 is elastically mounted on the lock body 6241, and an unlocking portion extending to the outside of the lock body 6241 is provided on the locking tongue 6243. When the locking tongue 6243 extends into the locking hole 6222, the locking tongue 6243 elastically moves and abuts against the locking portion 6223, and the movement of the locking tongue 6243 in the direction of leaving the locking hole 6222 is restricted. When it is necessary to release the lock cavity 6200 from holding the connecting portion 1305 tightly, the locking tongue 6243 is driven by the unlocking portion to move away from the locking portion 6223.

[0169] The second engagement structure: the locking tongue 6243 is fixedly arranged on the lock body 6241, the locking part 6223 is elastically installed on one side of the locking hole 6222, and the locking part 6223 is provided with an unlocking part extending to the outside of the first hinge seat 622. When the locking tongue 6243 extends into the locking hole 6222, the locking part 6223 elastically moves and abuts against the locking tongue 6243, thereby limiting the movement of the locking tongue 6243 in the direction of leaving the locking hole 6222. When it is necessary to release the lock cavity 6200 from holding the connecting part 1305 tightly, the locking part 6223 is driven by the unlocking part to move away from the locking tongue 6243.

[0170] It is understandable that both of the above-mentioned two engaging structures can meet the requirements of this embodiment. In the first engaging structure, the locking tongue 6243 can be elastically slidably mounted or elastically rotatably mounted; similarly, in the second engaging structure, the locking portion 6223 can be elastically slidably mounted or elastically rotatably mounted. In order to facilitate the description of the subsequent content, the subsequent content is described by taking the locking tongue 6243 and the locking portion 6223 using the above-mentioned engaging structure 1 as an example; and the locking tongue 6243 is elastically rotatably mounted.

[0171] Based on the above-mentioned engaging structure 1, the specific locking and unlocking process of the locking tongue 6243 and the locking portion 6223 is as follows: Figures 11 to 14As shown, when the locking tongue 6243 extends into the locking hole 6222, the locking tongue 6243 can first rotate around the installation position away from the locking portion 6223 under the action of elastic force, until the locking tongue 6243 passes over the locking portion 6223, and then the locking tongue 6243 can be reset and rotated to the first end to cooperate with the locking portion 6223 under the action of elastic force. When the buckle body 6241 has a movement tendency in the direction of opening the buckle cavity 6200, the first end of the locking tongue 6243 abuts against the locking portion 6223 to limit the rotation of the buckle body 6241, so as to ensure that the buckle body 6241 holds the connecting portion 1305 tightly. When it is necessary to disassemble the support member 134 and the cantilever portion 62, the unlocking portion located at the second end of the lock tongue 6243 is squeezed to drive the lock tongue 6243 to rotate around the installation position in the direction away from the locking portion 6223, so as to release the abutment between the first end of the lock tongue 6243 and the locking portion 6223, and then the lock body 6241 can rotate around the installation position in the direction of opening the lock cavity 6200.

[0172] In this embodiment, there are many specific installation structures of the lock tongue 6243, one of which is as follows: Figure 12 to Figure 14 As shown, the second end of the lock body 6241 is provided with an extension plate 6242, and the extension plate 6242 is provided with a mounting groove 6202, and the two adjacent sides of the mounting groove 6202 are respectively provided with a first opening 6203 and a second opening 6204. The locking tongue 6243 is elastically rotatably installed in the mounting groove 6202 through the second elastic member 6244, and the first end of the locking tongue 6243 can extend out of the first opening 6203, and the second end of the locking tongue 6243 can extend out of the second opening 6204 to form an unlocking portion. When the support member 134 and the cantilever portion 62 are installed, the extension plate 6242 can extend into the locking hole 6222 along with the lock body 6241, and then the locking tongue 6243 can rotate under the elastic force of the second elastic member 6244, so that the first end extends out of the first opening 6203 and is matched with the locking portion 6223. When the support member 134 needs to be disassembled from the cantilever portion 62, the second end of the locking tongue 6243 can be squeezed at the position of the second opening 6204 so that the locking tongue 6243 drives the first end to rotate into the installation groove 6202 until the first end of the locking tongue 6243 is out of contact with the locking portion 6223.

[0173] It should be known that the specific structure of the second elastic member 6244 is well known to those skilled in the art, and common elastic members include springs and spring sheets, etc. In this embodiment, the second elastic member 6244 is preferably a spring sheet.

[0174] In this embodiment, Fig.12As shown, the lock assembly 624 also includes a cover plate 6245 ; after the installation of the lock tongue 6243 and the second elastic member 6244 is completed, the installation groove 6202 can be closed by the cover plate 6245 to ensure the installation stability of the lock tongue 6243 .

[0175] To further facilitate understanding, the specific working process of the locking assembly 624 can be described in detail below.

[0176] Initially, the lock assembly 624 maintains the lock cavity 6200 in an open state through the lock body 6241 and the first hinge seat 622 .

[0177] When installing the support member 134 and the cantilever portion 62, the keyhole cavity 6200 in the open state can be aligned with the connecting portion 1305 at the bottom of the support member 134. Fig.14 As shown, the lock body 6241 is rotated around the installation position in the direction of closing the lock cavity 6200 until the extension plate 6242 provided at the second end of the lock body 6241 extends into the locking hole 6222. During the movement of the extension plate 6242 in the locking hole 6222, the locking portion 6223 can first squeeze the first end of the locking tongue 6243 so that the first end of the locking tongue 6243 is located in the installation groove 6202 and compresses the second elastic member 6244 to ensure that the extension plate 6242 can smoothly and completely extend into the locking hole 6222, that is, Fig.13 shown.

[0178] When the extension plate 6242 is fully extended into the locking hole 6222, Fig.13 As shown, the locking portion 6223 loses the squeezing of the locking tongue 6243, and then the locking tongue 6243 can rotate under the elastic force of the second elastic member 6244 until the first end of the locking tongue 6243 extends out of the first opening 6203 of the mounting groove 6202 and is located on one side of the locking portion 6223. At the same time, the lock body 6241 and the first hinge seat 622 are completely fitted to achieve the complete closure of the lock cavity 6200 to hold and lock the connecting portion 1305. In addition, when the lock body 6241 has a movement tendency in the direction of opening the lock cavity 6200, the movement tendency of the lock body 6241 can be limited by the abutment between the locking portion 6223 and the first end of the locking tongue 6243.

[0179] When it is necessary to disassemble the support member 134 and the cantilever portion 62, Fig.14As shown, the second end of the locking tongue 6243 can be squeezed at the second opening 6204 of the mounting groove 6202, so that the locking tongue 6243 can rotate with the first end toward the mounting groove 6202 until the first end of the locking tongue 6243 is completely located in the mounting groove 6202. Then, the locking tongue 6243 is kept in the state and the lock body 6241 is rotated until the lock cavity 6200 is fully opened to achieve separation from the connecting portion 1305.

[0180] Embodiment three:

[0181] Compared with the first embodiment and the second embodiment, the difference of this embodiment is that: Figure 1 and Fig.21 As shown, the child riding unit 1 includes a riding portion 11 for a child to ride or lie on, and a supporting portion 12 that supports the riding portion 11 and is placed in a flat environment. When the child riding unit 1 needs to be connected to the back-carrying unit 6, the child riding unit 1 is suitable for disassembling the supporting portion 12 so that the back-carrying unit 6 is supported and connected to the riding portion 11.

[0182] It is understandable that when the child does not need to be moved, if the child riding unit 1 is only used for the child to ride, then when the child riding unit 1 and the back-bearing unit 6 are disassembled and placed, an additional support structure is required to support and position the child riding unit 1; and the incompatibility of the support structure with the child riding unit 1 may result in a poor support effect. In this embodiment, the child riding unit 1 is divided into a matching riding portion 11 and a support portion 12; when the child does not need to be moved, the riding portion 11 and the support portion 12 are supported and connected to obtain a child riding unit 1 with a stable support structure. When the child needs to be moved, in order to avoid interference between the support portion 12 and the back-bearing unit 6, the support portion 12 and the riding portion 11 need to be disassembled first, and then the separate riding portion 11 and the back-bearing unit 6 need to be installed in coordination.

[0183] In this embodiment, there are many specific structures of the seating portion 11, one of which is as follows: Fig.21 and Fig. 22 As shown, the seat part 11 includes a seat body 111, a safety belt 112 and a support assembly 13. The seat body 111 is generally made of cloth material, which can provide a comfortable sitting and lying space for children. The safety belt 112 is installed on the seat body 111 to provide protection for the children sitting or lying. The support assembly 13 is a detachable structure, and the support assembly 13 can support the outer side of the seat body 111 at multiple points at the lower part of the seat body 111, thereby opening and propping up the seat body 111 made of cloth material.

[0184] It should be known that there are various specific structures of the seat body 111, and there are various specific supporting structures of the bracket assembly 13 for the seat body 111; generally speaking, in order to ensure the supporting stability of the seat body 111, the bracket assembly 13 needs to support at least the four corners of the seat body 111.

[0185] Specifically, Fig. 22 , Fig.23 and Fig.25 As shown, support sleeves 1110 are provided at the four outer corners of the seat body 111. The bracket assembly 13 includes four support rods 131; the four support rods 131 can be divided into a first group and a second group arranged front and back. The two support rods 131 of the first group can be detachably plugged into the support sleeves 1110 on both sides of the front of the seat body 111, thereby supporting the legs of the child when sitting. The two support rods 131 of the second group can be detachably plugged into the support sleeves 1110 on both sides of the rear of the seat body 111, thereby supporting the back of the child when sitting. That is, through the detachable plugging of the two groups of support rods 131 and the support sleeves 1110 at the four corners of the seat body 111, the child sitting on the seat body 111 can be supported as a whole.

[0186] In this embodiment, Fig. 22 , Fig.24 and Fig.25 As shown, the safety belt 112 generally adopts a five-point structure. That is, the safety belt 112 includes a pair of first straps 1121, a pair of second straps 1122 and a third strap 1123; the first strap 1121 can protect and restrain the child's shoulders, the second strap 1122 can protect and restrain the child's waist, and the second strap 1122 and the third strap 1123 can cooperate to protect and restrain the child's legs. Among them, the first strap 1121 and the third strap 1123 are directly connected to the seat body 111, and the second strap 1122 can pass through the seat body 111 and cooperate with the bracket assembly 13 to further improve the support stability of the seat body 111 while improving the protection effect of the safety belt 112.

[0187] It can be understood that the support points of the bracket assembly 13 on the seat body 111 are located on the front and rear sides of the seat body 111, and there are no support points in the middle area of the seat body 111, that is, the middle part of the seat body 111 is a suspended area. If the safety belt 112 is all connected to the seat body 111, when a child moves on the seat body 111, the safety belt 112 will drive the seat body 111 to move with the child, and thus there may be a risk of tipping over. In this embodiment, by passing the second strap 1122 of the safety belt 112 through the seat body 111 and connecting it to the bracket assembly 13, after the child sits on the seat body 111 and wears the safety belt 112, the movement range of the child, that is, the movement range of the seat body 111, will be restricted by the connection between the second strap 1122 and the bracket assembly 13; thus, while ensuring the safety of the child, the stability of the seat body 111 can also be improved.

[0188] In this embodiment, there are various specific connection structures between the second strap 1122 and the bracket assembly 13. One of the structures is as Fig.24 and Fig.25 shown. A connecting plate 133 is fixedly arranged in the middle of each of the second group of support rods 131. The connecting plate 133 can be fixed to the support rod 131 by means of screws or welding. The second strap 1122 can pass through the rear part of the seat body 111 and be detachably connected to the connecting plate 133, so as to provide a limiting force for the forward tilt of the seat body 111 through the rear structure of the bracket 13.

[0189] In this embodiment, as Fig.25 shown, the bracket assembly 13 further includes an armrest 132 for supporting the child riding unit 1. The armrest 132 is integrally in a "U" shape, and it can be detachably and fixedly connected to the two support rods 131 of the second group at both ends. Thus, when the child riding unit 1 is used for traveling, by supporting the armrest 132, it is convenient to adjust the position of the child riding unit 1 and ensure the safety of using the child riding unit 1.

[0190] In this embodiment, as Fig. 22 and Fig.26 shown, the bracket assembly 13 further includes a support rod 135, and the support rod 135 is connected between the two support rods 131 of the first group. Thus, when a child sits on the seat body 111, the support rod 135 can support the front part of the seat body 111, so that a concave space is formed on both sides of the front part of the seat body 111 under the gravity of the child's legs, and thus it can prevent the discomfort caused by the child's legs getting close to each other under the action of gravity.

[0191] It should be known that the supporting points of the two supporting rods 131 of the first group for the seat body 111 are located at the ends of the two sides of the front part of the seat body 111; that is, the two supporting rods 131 of the first group do not support the front middle area of ​​the seat body 111, so that the tensioning capacity of the front middle area of ​​the seat body 111 is poor. When a child sits on the seat body 111, under the action of the weight of the child's legs, the front middle area of ​​the seat body 111 will be sunken downward, so that the front two sides of the seat body 111 are tilted, which will cause the child's legs to frequently fit together, that is, the front two sides of the seat body 111 will produce a sense of restraint for the child's legs to move closer to the middle.

[0192] In this embodiment, by providing a support rod 135, the front middle of the seat body 111 can be supported, so that a concave area for placing the child's legs is formed on each side of the front of the seat body 111; thereby, the riding comfort of the child can be effectively improved.

[0193] Specifically, Fig.26 As shown, the middle part of the support rod 135 is arched, so that when the support rod 135 is connected to the first group of support rods 131, the support rod 135 can support the front middle area of ​​the seat body 111 through the arch in the middle part, so that when a child sits on the seat body 111, a concave area can be formed on both sides of the front.

[0194] It should be known that there are many ways for the support rod 135 to support and cooperate with the front middle area of ​​the seat body 111 through the arch in the middle, including but not limited to the following two ways.

[0195] Method 1: If Fig. 22 and Fig.23 As shown, a groove 1111 opening downward is provided on the outer side of the front middle area of ​​the seat body 111 ; the middle arch of the support rod 135 can be inserted upward into the groove 1111 to support the front of the seat body 111 .

[0196] Method 2: A sleeve opening downward is provided on the outer side of the front middle area of ​​the seat body 111 , and the middle arch of the support rod 135 can extend into the sleeve opening to support the front of the seat body 111 .

[0197] It is understandable that, for the first method, a hard support block can be fixedly arranged outside the front middle area of ​​the seat body 111, and the notch 1111 is arranged on the support block. Similarly, for the second method, a piece of cloth can be sewn outside the front middle area of ​​the seat body 111; the cloth can form a sleeve with an opening downwards with the seat body 111.

[0198] In this embodiment, Fig.26 and Fig. 27 As shown, the middle of the two supporting rods 131 of the first group is provided with a socket, and both ends of the supporting rod 135 are provided with a locking groove 1350. When installing the supporting rod 135, the two ends of the supporting rod 135 can be respectively inserted into the sockets on the two supporting rods 131 of the first group; then the fastener 136 is extended into the socket along the outside of the socket and cooperates with the locking groove 1350 through the fastener 136 along the support rod 135, thereby limiting the movement of the supporting rod 135 along the axial direction.

[0199] It should be known that the support rod 135 has a certain degree of flexibility, so when a child sits on the seat body 111, for a child with a large weight or a large range of motion, the support rod 135 may be greatly bent due to the gravity or impact, which can easily cause the two ends of the support rod 135 to separate from the corresponding support rod 131. Therefore, the present application sets locking grooves 1350 at both ends of the support rod 135, and the rod segment diameter corresponding to the locking grooves 1350 is smaller than the diameter of other rod segments of the support rod 135. After the support rod 135 and the support rod 131 are connected, the support rod 135 can be effectively prevented from separating by tightening the fastener 136 and engaging with the locking groove 1350.

[0200] In this embodiment, Fig. 22 , Fig.24 and Fig.28 As shown, the seat portion 11 further includes a headrest assembly 113, which is mounted on the rear portion of the seat body 111 for supporting the child's head. The height of the headrest assembly 113 can be adjusted to accommodate children of different sizes.

[0201] Specifically, Fig.28 As shown, the headrest assembly 113 includes a pillow portion 1131 and an insertion rod 1132; the pillow portion 1131 can be detachably installed with the upper end of the insertion rod 1132, so that the pillow portion 1131 is connected to the rear portion of the seat body 111 through the insertion rod 1132, and the insertion rod 1132 can adjust the height of the pillow portion 1131 by engaging with different areas of the rear portion of the seat body 111, thereby adapting to children of different body shapes.

[0202] In this embodiment, there are many specific structures for the insertion rod 1132 to cooperate with the seat body 111 to adjust the height of the pillow portion 1131, one of which is as follows: Fig.24 and Fig.28As shown, there are a pair of insertion rods 1132, and both of the two insertion rods 1132 have a certain deflection. At the lower ends of the insertion rods 1132, there are provided protruding engaging portions 1133, and the protruding directions of the engaging portions 1133 of the two insertion rods 1132 are opposite. At the rear part of the seat body 111, there are provided a pair of adjusting sleeves 1113 with insertion holes. At the side part of the adjusting sleeve 1113, a plurality of notch grooves 1114 are arranged at intervals along the extending direction of the insertion hole, and the opening directions of the notch grooves 1114 on the two adjusting sleeves 1113 are also opposite.

[0203] When installing the headrest assembly 113, the insertion rods 1132 can be inserted along the insertion holes of the corresponding adjusting sleeves 1113; when the headrest part 1131 is in a proper position, the insertion of the insertion rods 1132 can be stopped, and at this time, the insertion rods 1132 can be engaged with the corresponding notch grooves 1114 through the engaging portions 1133, so as to limit the position of the headrest part 1131.

[0204] It should be known that the cross-sectional dimension of the adjusting sleeve 1113 is adapted to the dimension of the engaging portion 1133 of the insertion rod 1132, so as to ensure that the insertion rod 1132 can be smoothly inserted into the adjusting sleeve 1113. After the insertion of the insertion rod 1132 is completed, the insertion rod 1132 and the adjusting sleeve 1113 can be in a natural state or an elastically abutted state, that is, the distance between the two adjusting sleeves 1113 is less than or equal to the distance between the two insertion rods 1132. Therefore, when installing the insertion rod 1132, the two insertion rods 1132 can be squeezed against each other to reduce the distance for convenient installation.

[0205] Meanwhile, the specific number of the notch grooves 1114 can be selected according to the actual needs of those skilled in the art. For example Fig.24 As shown, the number of the notch grooves 1114 is four.

[0206] In this embodiment, there are mainly two ways of arranging the insertion rods 1132; the first one is that the two insertion rods 1132 are independent of each other, and the two insertion rods 1132 are detachably fixedly connected to the headrest part 1131 through the upper ends, and at the same time, are correspondingly inserted into the adjusting sleeve 1113 through the lower ends; the second one is that a long rod is bent into a "U" shape or a "凵" shape to obtain two parallel insertion rods 1132; then the headrest part 1131 can be detachably installed in the bending area of the long rod by sleeving or other means, and is inserted and installed on the seat body 111 through the formed insertion rods 1132.

[0207] In this embodiment, as Fig.24As shown, the setting position of the adjustment sleeve 1113 is located at the middle or lower part of the rear side of the seat body 111; at the same time, a pair of guide buckles 1112 are provided at the upper part of the rear side of the seat body 111, and the insertion rod 1132 can penetrate the corresponding guide buckles 1112 and be plugged into the corresponding adjustment sleeve 1113. Therefore, the support length of the insertion rod 1132 and the seat body 111 can be effectively increased, so as to further improve the use stability of the headrest assembly 113.

[0208] In this embodiment, Fig.25 , Figure 29 to Figure 31 As shown, the bracket assembly 13 also includes a support member 134 , and each support rod 131 can be detachably connected to the support member 134 through the lower end; at the same time, the support portion 12 can also be detachably connected to the support member 134 to support the seating portion 11 .

[0209] In this embodiment, Fig.25 As shown, the support rod 131 includes a first rod body 1311 and a second rod body 1312 that are detachably connected; the lower end of the first rod body 1311 is detachably connected to the support member 134, and the upper end of the second rod body 1312 is used to support the seat body 111. The first rod body 1311 and the second rod body 1312 are arranged obliquely so that the second rod body 1312 supports the seat body 111 vertically or vertically, thereby effectively avoiding contact between the seat body 111 and the second rod body 1312, so as to improve the riding comfort of the seat body 111.

[0210] Specifically, Fig.25 and Fig.29 As shown, the support member 134 includes a second support seat 1341, and the side of the second support seat 1341 is obliquely provided with insertion holes corresponding to the number of the support rods 131; the support rods 131 can be detachably plugged into the corresponding insertion holes through the lower end of the first rod body 1311. In addition, in order to prevent the support rods 131 from rotating relative to each other during use, the cross-sectional shapes of the insertion holes and the support rods 131 can be designed to be non-circular, or the fasteners 136 can be used to tighten the support rods 131 into the insertion holes.

[0211] In this embodiment, Fig.29 , Fig.30 and Fig.31As shown, the support portion 12 can be detachably supported and connected to the support member 134 at the bottom of the bracket assembly 13. The support portion 12 includes a plurality of first support seats 121 and a plurality of legs 122. The first support seats 121 are vertical plates, and at least one leg 122 is detachably connected to each first support seat 121, and the total number of legs 122 is at least equal to three. A plurality of slots 1301 with openings facing downward are provided along the circumferential direction at the bottom of the support member 134, and the number of slots 1301 corresponds to the number of first support seats 121. When the support portion 12 is supported and connected to the riding portion 11, the first support seats 121 can be vertically inserted into the corresponding slots 1301.

[0212] It can be understood that, for the stability of the support structure, the number of legs 122 included in the support portion 12 is at least three, and the specific number can be selected according to actual needs. For example, Fig.30 and Fig.31 as shown, the number of legs 122 is four. At the same time, the specific number of the first support seats 121 can be selected according to actual needs. For example, Fig.30 and Fig.31 as shown, the number of the first support seats 121 is a pair, and two legs 122 are symmetrically and obliquely inserted on each first support seat 121. Since the openings of the slots 1301 face downward, after the first support seats 121 are inserted into the slots 1301, when the support member 134 bears weight, the insertion of the first support seats 121 and the slots 1301 is more stable.

[0213] Specifically, as Fig.29 shown, the support member 134 further includes a connecting seat 1342, and the connecting seat 1342 is connected to the second support seat 1341. The connecting seat 1342 is in a "U" shape, so that the slots 1301 can be symmetrically arranged on both sides of the connecting seat 1342.

[0214] It can be understood that in the above-mentioned first embodiment, as Figure 4 shown, the connecting seat 1342 can be fixedly connected to the lower end of the retaining sleeve 1345 through fasteners such as bolts. Further, when disassembling the support member 134 and the cantilever portion 62, for convenient operation, the retaining sleeve 1345 can be axially moved by driving the connecting seat 1342.

[0215] At the same time, to ensure the use stability of the connecting seat 1342, as Figure 4 and Figure 6As shown, a guide groove 1304 can be provided on the outer side of the support sleeve 1343, and a guide block 1308 can be provided on the inner side of the stopper sleeve 1345. The support sleeve 1343 can be slidably matched with the guide block 1308 of the stopper sleeve 1345 through the guide groove 1304, so that the stopper sleeve 1345 can only move axially relative to the support sleeve 1343, thereby ensuring that the connecting seat 1342 will not deflect during use.

[0216] In this embodiment, Figures 35 to 38 As shown, when transporting the product or the user is traveling, in order to reduce the carrying space of the child riding unit 1, the riding part 11 and the supporting part 12 can be completely disassembled. Among them, the riding part 11 can be disassembled to obtain a separate seat body 111, a support member 134, an armrest 132, an insertion rod 1132, a plurality of first rods 1311, and a plurality of second rods 1312. Since the seat body 111 is made of cloth, it can be folded; since the armrest 132, the insertion rod 1132, a plurality of first rods 1311, and a plurality of second rods 1312 are all rods, they can be gathered into bundles for carrying. Among them, the supporting part 12 can be disassembled to obtain a separate first support seat 121 and a plurality of legs 122; the plurality of legs 122 are also rods, which can be gathered into bundles together with the rods of the bracket assembly 13.

[0217] Embodiment 4:

[0218] Compared with the third embodiment, the difference of this embodiment is that: Figure 32 to Figure 34 As shown, the support portion 12 can be detachably supported and connected with the support member 134 at the bottom of the bracket assembly 13. The support portion 12 includes a first support seat 121 and at least three legs 122; the plurality of legs 122 are plugged along the circumference of the first support seat 121. A through hole 1302 is provided at the center of the support member 134, and the first support seat 121 can be plugged with the through hole 1302 through a plug post 1210 vertically provided at the top center, thereby realizing a detachable connection between the support portion 12 and the support member 134; and the gravity of the seating portion 11 is always downward, which will drive the plugging of the through hole 1302 of the support member 134 and the plug post 1210 to always remain stable.

[0219] It should be known that the specific number of the legs 122 can be selected according to the implementation requirements, but in order to ensure the support stability, the number of the legs 122 is at least three. Fig.33 As shown, there are four legs 122 , and the four legs 122 can be plugged into the first support seat 121 in a circumferential direction around the first support seat 121 , or two legs 122 can form a group, and two groups of legs 122 are symmetrically plugged into the first support seat 121 .

[0220] Specifically, Fig.32 and Fig.34 As shown, the support member 134 includes a second support seat 1341 and a support sleeve 1343; the specific fixing method of the support sleeve 1343 and the second support seat 1341 is the same as that of the first embodiment; the through hole 1302 is arranged at the center of the support sleeve 1343. When the support portion 12 and the support member 134 are installed, the support portion 12 can be inserted into the through hole 1302 of the support sleeve 1343 through the plug 1210 arranged on the upper end surface of the first support seat 121 to achieve a detachable connection.

[0221] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
