The seat portion, the upright sidewalls, and the seat back of the seat member 1210 cooperate to define a generally hollow interior. Furthermore, a front portion of the seat member 1210 is open to accommodate the legs of a child when the child is seated in the hollow interior. In one embodiment, the seat member 1210 is intended for use by a toddler or infant capable of supporting themselves in an upright position, such as a child typically six months or older. Thus, the seat member 1210 is adapted to receive a child seated in contact with the seat member 1210,The child's back is at least partially supported by the seat back. With continued reference to FIGS. 1-3, the seat member 1210 is supported by a plurality of legs 1214a-1214d spaced apart from one another. In the illustrated non-limiting embodiment, a leg is generally disposed near each corner of the seat member 1210. Thus, as shown, the high chair includes a first right front leg 1214a, a second left front leg 1214b, a third right rear leg 1214c, and a fourth left rear leg 1214d. In one embodiment, each of the plurality of legs can be substantially identical. However, in other embodiments, the configuration of the legs can vary. For example, the rear legs 1214c, 1214d can have a first configuration, and the front legs 1214a, 1214b can have a second configuration different from the first configuration. For example, while the overall cross-sectional shape and size of the front and rear legs 1214a, 1214b, 1214c, 1214d appear identical, the axial length of the rear legs 1214c, 1214d is greater than the axial length of the front legs 1214a, 1214b. The distal end 1215 of each of the front legs 1214a, 1214b and the rear legs 1214c, 1214d is configured to contact a support surface, such as a floor, to support the high chair in an upright configuration. As shown, the proximal opposite end 1216 of each leg 1214a, 1214b, 1214c, 1214d is fixed to a respective portion of the seat member 1210. Further, the cradle body 1100 includes a mounting member 1110 that allows it to be attached to the high chair frame, as described in greater detail below. The mounting member 1110 is designed to be adaptable, for example, enabling the cradle to be easily converted between a high chair and a cradle stand or bouncer. The mounting member 1110 ensures a secure attachment, preventing any accidental movement or disassembly. FIG. 4 is an isometric view showing an exemplary or representative embodiment of the mounting member 1110 of the cradle. FIGS. 5A and 5B are plan cross-sectional views showing a sequence of engagement steps of an exemplary or representative embodiment of the cradle on a high chair in a release-locked state or configuration and during locking, respectively. FIG. 6 is an enlarged plan view showing an exemplary or representative embodiment of a locking mechanism. With reference to FIGS. 4-6, the exemplary or representative cradle can be connected to the seat member 1210 by at least one mounting member 1110. As best shown in FIG. 4, in one embodiment, a first mounting member is disposed at a first end of a bumper member, and a second mounting member is disposed at a second end of the bumper member. In some cases, the mounting member 1110 is permanently fixed or integrally formed with the cradle. For example,The mounting members 1110 can be injection molded pieces that are snap-fit onto the bassinet. An example of the mounting members 1110 installed within respective openings is shown in FIG. 5A. The at least one mounting member 1110 can be received within a respective opening or cavity formed in a portion of the seat member 1210. For example, a first mounting member can be slidably and / or rotatably received within a first opening 1211a formed at a front surface of the first upright sidewall 1211, and a second mounting member can be slidably and / or rotatably received within a second opening 1212a formed at a front surface of the second upright sidewall 1212 (see FIG. 16). With reference to FIG. 6, additional details of the mounting members 1110 with a locking mechanism are shown. As shown, each mounting member 1110 can include a body 1111. The body 1111 has a first end 111 la connectable to the bassinet and a second end 111 lb connectable to the seat member 1210. A gap 1112 extends over a portion of the length of the body 1111, such that the body 1111 includes a primary finger 1113 and a secondary finger 1114 at its second end 111 lb. The primary finger 1113 and the secondary finger 1114 are connected to each other at the first end 111 la of the body 1111, but are separated from each other over the length of the gap 1112. The gap 1112 can have a non-linear configuration, or alternatively can have a linear configuration. In the non-limiting embodiment shown, the gap 1112 includes a first straight portion and a second arcuate or curved portion disposed at the second end 111 lb of the body 1111. However, gaps 1112 having any suitable configuration are contemplated herein. Accordingly, the resulting primary finger 1113 and secondary finger 1114 can have any suitable configuration. In one embodiment, the secondary finger 1114 is flexible or bendable relative to the primary finger 1113, for example during installation or disconnection of the mounting member 1110 from the seat member 1210. To connect the bassinet to the seat member 1210, the at least one mounting member 1110 is inserted into the at least one opening 1210a, 1220b formed around the seat member 1210. As the mounting member 1110 is slidably inserted into the opening 1210a, 1220b, the secondary finger 1114 is configured to bend towards the primary finger 1113. When the mounting member 1110 reaches a fully inserted position, as shown in FIG. 5B, a portion of the secondary finger 1114 can be disposed outside of the seat member 1210. Outside of the seat member 1210, the secondary finger 1114 is no longer restricted by the overall height of the opening 1210a, 1220b, and thus can bias to its original position. In one embodiment,The secondary finger 1114 includes a notch 1115 configured to mate with a surface of the seat member 1210 to limit lateral movement of the cradle away from the seat member 1210. To disengage the cradle from the seat member 1210, an upward force, shown by F1, is applied to the exposed portion of the secondary finger 1114. This force causes the secondary finger 1114 to flex toward the primary finger 1113, aligning the primary and secondary fingers 1113, 1114 of the mounting member 1110 with the openings 1210a, 1220b for removal therefrom. The mounting member 1110 can include a flexible material, such as an engineered resin or a thermoplastic material. In the illustrated non-limiting embodiment, the primary finger 1113 extends axially beyond the secondary finger 1114. Thus, when the mounting member 1110 is installed within the openings 1210a, 1220b, the second end of the primary finger 1113 is configured to engage and rest on a shelf 1213 formed in the openings 1210a, 1220b. This engagement between the primary finger 1113 and the shelf 1213 is configured to resist rotation of the cradle and to mitigate stress on the secondary finger 1114. For example, with reference to the orientation of the cradle in FIGS. 2 and 5B, an upward force applied to the cradle can be transmitted to the engagement of the primary finger 1113 with the shelf 1213, rather than to the secondary finger 1114. As shown, the interior of the cradle body 1100 has, for example and without limitation, a soft item or cushioning pad (insert),to provide comfort.

FIG. 12 is a diagram illustrating an isometric view of an example or representative embodiment of a bassinet on a high chair in a first configuration including a suspension attachment 1120. FIGS. 13A and 13B are diagrams illustrating a sequence of installation steps of an example or representative embodiment of a bassinet on a high chair in a first configuration in an uninstalled state or configuration, an installation process, and an installed state or configuration, respectively, in isometric views. FIG. 14 is a diagram illustrating an isometric rear view of an example or representative embodiment of a bassinet on a high chair in a first configuration including a suspension attachment 1120. Referring to FIGS. 7A-14, the example or representative modular bassinet seat system 10 includes a bassinet body 1100 that is installed onto a high chair frame in a first configuration and a bassinet body 1100 that is installed onto a bassinet stand in a second configuration. In the illustrated non-limiting embodiment, the bassinet body 1100 can be easily installed on a bassinet stand (e.g., a cradle, a rocker bar, or other suitable attachment) by aligning the mounting members 1110 and engaging the locking mechanism, thereby providing another independent mode of operation for the bassinet of the disclosed system. As shown in FIG. 7A, the bassinet body 1100 is installed on a high chair via the mounting members 1110 and the locking mechanism. Similarly, as shown in FIG. 7B, the bassinet body 1100 can be coupled to a bassinet stand o The manner in which the bassinet is installed on the bassinet stand can be configured in a manner similar to that described above, except that curved legs replace the high chair legs, as described in greater detail below. In some cases, the bassinet stand includes at least one curved base (or rocker bar or curved plate or other suitable support) for receiving the bassinet body 1100 on a support surface (e.g., a floor), the curved base can be configured to have a continuous curvature,An arch that curves upward from the bottom. To avoid unwanted slippage during use, the underside of the curved base can have a non-slip strip, such as a rubber band or non-slip layer, typically extending the length of the curved base. Further, those skilled in the art will recognize that the size, shape, and material selection of the non-slip strip should be strong enough for its intended use and application, and is typically determined, for example and without limitation, based on its application and expected stress or weight load, as well as aesthetic considerations. In the representative embodiment of the cradle frame shown in the second configuration, support members configured to support the cradle body 1100 are disposed on the upper surface of the curved base. Similarly, openings or cavities are formed in a portion of the support members that are configured to receive corresponding mounting members 1110 of the cradle body 1100. For example, a first mounting member of the cradle body 1100 can be slidably and / or rotatably received within a first opening formed at an upper portion of a first support member of the cradle frame, and a second mounting member of the cradle body 1100 can be slidably and / or rotatably received within a second opening formed at a lower portion of a second support member of the cradle frame. In the representative embodiment shown, the support members also include an arcuate or curved portion disposed at an upper portion of the support members. Further, while shown with substantially rounded edges, those skilled in the art will recognize that numerous other designs are available and are substantially equivalent, for example and without limitation, as shown in the various figures. In the representative embodiment of the cradle frame shown, the support members can be provided with release members configured to unlock the mounting members 1110. In exemplary or representative embodiments, the release members can have any of a variety of shapes or sizes that are symmetrical or asymmetrical, for example and without limitation, such as a button shape, a pear shape, a triangular shape, a rectangular shape, a spherical shape, a tab shape, a bulb shape, or a bulbil shape, or as shown, a semi-elliptical or oval shape, any shape that is manipulated and / or slid by a caregiver's thumb or finger. With reference to FIGS. 8A-14, additional embodiments of the cradle body 1100 on a high chair in a first configuration and on a cradle frame in a second configuration are shown. In the first configuration, the cradle body 1100 is connected to a high chair; while in the second configuration, the cradle body 1100 is connected to a cradle frame. For example, FIG. 9B shows an additional embodiment of the cradle body 1100 on a cradle frame in a second configuration, in which the combination of the cradle frame and the cradle body can also be referred to as a rocking chair. With reference to FIGS. 13A and 13B, another representative embodiment of the cradle body 1100 on a high chair is shown. The cradle body 1100 has a support member that protrudes downward from a base of the cradle body 1100, wherein the base has a recess to receive, for example and without limitation, an infant therein. As shown,The mounting member 1110 of the bassinet body 1100 extends from the rear side of the support member of the base, and the mounting member 1110 is receivable within a corresponding opening or cavity formed in a portion of the seat member 1210 of the high chair. Further, while shown as having a substantially elongated edge, those skilled in the art will recognize that innumerable other designs are available and substantially equivalent, for example, but not limited to, as shown in the various figures,

[0003] O As shown in FIGS. 12 and 14, in the illustrated representative embodiment of the bassinet body 1100 on the high chair, the bassinet can be equipped with a hanging attachment 1120 for holding accessories such as a toy bar, a mobile device (a cell phone), a projector, an audio unit, a light bar, or other suitable units when the bassinet body 1100 is in the first configuration. FIG. 15 is a diagram showing an isometric view of an exemplary or representative embodiment of a high chair including a crotch member 1220. FIG. 16 is a diagram showing an isometric view of an exemplary or representative embodiment of a high chair and a crotch member 1220 in a disassembled state. FIGS. 17-19 are diagrams showing a sequence of engagement steps of an exemplary or representative embodiment of a crotch member 1220 on a high chair in a released or configuration and during a locking process, respectively, in plan cross-sectional views. In the illustrated non-limiting embodiment, the crotch member 1220 of the arm bar is not configured to couple with the seat member 1210 per se. Rather, the crotch member 1220 is positioned in the desired location due to the connection between the bumper member and the seat member 1210 via one or more mounting members 1110. However, embodiments in which a portion of the crotch member 1220 is also connected to the seat member 1210 are also within the scope of the present disclosure. FIG. 20 is a diagram showing an isometric view of an exemplary or representative seat member 1210 and legs of an exemplary or representative high chair embodiment in a disassembled state. FIG. 21 is a diagram showing an isometric view of an exemplary or representative seat member 1210 and legs of an exemplary or representative high chair embodiment in an assembled state. As shown, at least one of the legs 1214a, 1214b, 1214c, 1214d is detachably connectable to a corresponding portion of the seat member 1210. In the illustrated non-limiting embodiment, at least one of the plurality of legs, such as the rear legs 1214c, 1214d, is connectable to the seat member 1210 by a quick-connect coupling mechanism (FIGS. 20 and 21) without the need to use any additional or external tools, such as a screwdriver. FIG. 22 is a diagram showing an isometric view of an exemplary or representative high chair embodiment with an arm bar including a tray 1230. As shown, the tray 1230 can be mounted to a portion of the high chair. The tray 1230 can have a generally flat upper surface configured to support items, such as food, at a location that is easily accessible to an occupant of the seat member 1210. In the illustrated non-limiting embodiment, the tray 1230 can be positioned in an overlapping arrangement with an upper surface of the arm bar.Although a portion of the tray 1230 can contact or abut an adjacent surface of the seat member 1210, such as a front portion of an upstanding sidewall, the tray 1230 is not configured to couple with or be supported by any portion of the seat member 1210. As used herein, the term "couple" is intended to mean a mechanical connection or fastening that restricts the relative movement of two or more components in at least one direction. In contrast, in an embodiment, the tray 1230 is configured to only couple or attach directly to the arm. Thus, in an embodiment, the tray 1230 cannot be coupled to the high chair when the arm is not connected to the high chair. Referring to FIG. 23, a perspective view of a child seat (which can also be referred to as a rocker) 20 of an embodiment of the present disclosure is shown, where the child seat 20 is in an installed position. In particular, FIG. 23 shows the child seat 20 viewed from an oblique front side. The child seat 20 can include a seat assembly 2100 and a chassis assembly 2200 to support the seat assembly 2100. The seat assembly 2100 is fixedly connected to the chassis assembly 2200 when the child seat 20 is in a locked position and can be detached from the chassis assembly 2200 when the child seat 20 is in an unlocked position. The seat assembly 2100 can support and mount a seat and / or a seat pad to place a child on the seat and / or seat pad. The child seat 20 shown in FIG. 23 is a child seat 20 that can rock back and forth to entertain a child. The child seat 20 has a generally left-right symmetrical structure. The seat assembly 2100 can include a seat frame 2110 to support and mount a seat and / or a seat pad and a docking station 2120. The docking station 2120 is disposed on an underside of the seat frame 2110 and can be mounted to the chassis assembly 2200. In an embodiment, the seat frame 2110 can have a generally rectangular frame configuration. However, the present disclosure is not limited thereto and other shapes such as an oval shape, a circular shape, etc. are possible. The seat frame 2110 can be a one-piece or can be assembled from multiple parts. Typically, the seat frame 2110 can be a tubular member made from a hollow tube. The seat frame 2110 shown in FIG. 23 is made from a hollow tube having a generally rectangular cross-section and the hollow tube has a flat top surface and a flat bottom surface. The flat top surface can support and mount a seat and / or a seat pad and the flat bottom surface can mount the docking station 2120. The seat frame 2110 designed in this manner is not only strong and reliable but also easy to manufacture. In an embodiment, the seat frame 2110 can be detachably mounted to the docking station 2120. Alternatively, the seat frame 2110 can be integrally formed with the docking station 2120.To this end, the docking seat 2120 can extend from the seat frame 2110 (e.g., from the bottom surface of the seat frame 2110) toward the chassis assembly 2200, in other words, downward along the first direction shown in FIG. 23. Herein, the “first direction” can be understood as a direction forming a non-zero included angle with the vertical direction, so that the seat frame 2110 can be arranged in an inclined manner relative to the support surface for arranging the child seat 20. Here, the “vertical direction” means a direction perpendicular to the support surface (e.g., the ground) for arranging the child seat 20. In this way, the child can lie in the child seat 20 in an inclined manner with the head higher than the hips. The width of the upper surface of the docking seat 2120 is optionally matched with the width of the lower surface of the seat frame 2110. The docking seat 2120 can be fixed at the lateral sides of the seat frame 2110 at a position slightly lower in the longitudinal direction of the seat frame 2110, so as to facilitate the overall child seat 20 to be in a front-low and rear-high posture when in a stationary state. For example, the midpoint of the connection position of the docking seat 2120 and the seat frame 2110 can be in the front 1 / 3-1 / 2 range of the length of the seat frame 2110, so that the seat assembly 2100 can be installed above the chassis assembly 2200 and at a distance from the support surface, so that the seat assembly 2100 does not collide with the support surface when the child seat 20 swings forward and rearward. The chassis assembly 2200 can include a connecting seat 2210, a rocker 2220, and a support rod 2230. The rocker 2220 can be provided in two, which are respectively arranged at the lateral (left and right) sides of the child seat 20. Each rocker 2220 can be an arc-shaped rod member extending substantially in the longitudinal direction (i.e., the front-rear direction shown in FIG. 24), so that the chassis assembly 2200 can swing forward and rearward on the support surface but is not prone to overturning. The two rockers 2220 can be arranged parallel to each other on the support surface; or alternatively, the two rockers 2220 are arranged such that the distance between the two front ends is less than the distance between the two rear ends. Each rocker 2220 can be provided with a connecting seat 2210, for example, the connecting seat 2210 can be arranged on the top surface of the rocker 2220, and the width of the bottom surface of the connecting seat 2210 is optionally matched with the width of the top surface of the rocker 2220. The connecting seat 2210 can extend from the top surface of the rocker 2220 toward the seat assembly 2100, in other words, upward along the first direction. The connecting seat 2210 can be fixed substantially at a position intermediate in the longitudinal direction of the rocker 2220. For example, the midpoint of the connection position of the connecting seat 2210 and the rocker 2220 can be in the front 1 / 3-1 / 2 range of the length of the rocker 2220.The support rods 2230 can be arranged between the two rocker levers 2220 on both sides of the child seat 20 to increase the overall rigidity of the chassis assembly 2200. The support rods 2230 can be arranged in one, two or more, which can be selected according to the specific configuration of the chassis assembly 2200 and the load bearing condition to ensure its firmness and safety. In an embodiment, two support rods 2230 are optionally arranged transversely between the two longitudinally extending rocker levers 2220 in parallel with each other. Alternatively, the two support rods 2230 can be arranged between the two rocker levers 2220 in a non-parallel manner, for example, in a cross manner. The two ends of the support rods 2230 are connected to the mutually facing inner sides of the two rocker levers 2220, respectively, so that the chassis assembly 2200 is formed as a rigid whole, while ensuring the structural stability of the child seat 20 when rocking. In an embodiment, the connecting seat 2210 can be provided with a release operation member 2240 on the surface facing the transversely outward side. Considering the convenience of operation, the release operation member 2240 can be located at a position near the upper part of the connecting seat 2210 in the vertical direction. When the child seat 20 is in the locked state, the outer surface of the release operation member 2240 is substantially flush with the outer surface of the connecting seat 2210, so that the overall appearance of the child seat 20 is more beautiful, and at the same time, it can also prevent improper operation caused by accidental contact by the user. In other embodiments, the release operation member 2240 can be arranged at other positions. The seat assembly 2100 and the chassis assembly 2200 are detachably connected through the clamping and dismounting structure between the plug-in seat 2120 and the connecting seat 2210. The lower surface shape of the plug-in seat 2120 can match the upper surface shape of the connecting seat 2210. Moreover, the shape of the circumferential surface of the plug-in seat 2120 can match the shape of the circumferential surface of the connecting seat 2210. When the plug-in seat 2120 is plugged onto the connecting seat 2210 so that the seat assembly 2100 and the chassis assembly 2200 are installed in place, the circumferential wall of the plug-in seat 2120 is flush with the circumferential wall of the connecting seat 2210, making the product more beautiful. When the child seat 20 is in a stationary state, the transverse projection length of the seat frame 2110 on the horizontal plane can be equal to or slightly less than the transverse projection length of the two rocker levers 2220 on the horizontal plane, which is beneficial to the overall stability of the child seat 20. Referring to FIG. 24, it shows a perspective view of the child seat 20 in a disassembled state according to an embodiment of the present disclosure. The seat frame 2110 can be composed of a first frame 2111 and a second frame 2112 connected together. Optionally, the first frame 2111 and the second frame 2112 are fixedly butted to each other to form a closed loop-shaped seat frame 2110.The first frame 2111 and the second frame 2112 can be substantially left-right symmetrical and abut each other. The first frame 2111 and the second frame 2112 are optionally in the shape of a U, and the two free ends of the U abut each other. The two free ends of the first frame 2111 and the two free ends of the second frame 2112 can be connected in a plug-in manner. Specifically, one of the two free ends of the first frame 2111 and the corresponding free end of the second frame 2112 is provided as a large-end interface 2113 conforming to the outer peripheral contour of the seat frame 2110, and the other can be provided as a small-end interface 2114 conforming to the inner peripheral contour of the large-end interface 2113 by, for example, a shrinkage tube process. The small-end interface 2114 can be inserted into and fixed in the large-end interface 2113, thereby achieving the fastened assembly of the first frame 2111 and the second frame 2112. The abutting large-end interface 2113 and small-end interface 2114 shown in FIG. 24 are merely an example on the first frame 2111 and the second frame 2112, and the two can be interchanged as needed. In an embodiment, the small-end interface 2114 can be provided with a spring piece and a protrusion (not shown). For example, the spring piece can be a spring leaf fixed in the small-end interface 2114, and the protrusion can be a protrusion provided on the active end of the spring leaf (not shown). The small-end interface 2114 and the large-end interface 2113 are respectively provided with through holes at positions corresponding to the protrusion, to allow the protrusion to elastically shuttle therebetween when the through holes of the small-end interface 2114 and the large-end interface 2113 are aligned with each other. Specifically, when the small-end interface 2114 is inserted into the large-end interface 2113, the protrusion extending from the through hole of the small-end interface 2114 is retracted inward against the constraint of the inner wall of the large-end interface 2113 to overcome the elastic force of the spring piece, until the small-end interface 2114 is smoothly inserted to a predetermined position in the large-end interface 2113 (i.e., the through holes of the small-end interface 2114 and the large-end interface 2113 are substantially aligned), at which time the protrusion extends into the corresponding through hole of the large-end interface 2113 provided outside the small-end interface 2114 under the elastic force of the spring piece, so as to achieve the clamping connection of the small-end interface 2114 and the large-end interface 2113, thereby clamping the second frame 2112 and the first frame 2111. If disassembly is needed, the protrusion in the through hole of the large-end interface 2113 can be pressed from the outside so that the protrusion can be retracted to the inside of the small-end interface 2114 from the through hole of the large-end interface 2113, thereby releasing the clamping between the small-end interface 2114 and the large-end interface 2113.It can be understood that the elastic member and the protruding member can be replaced by other reset elements with reset function, which will not be described herein. In an embodiment, the seat frame 2110 can also be formed by two or more than two tubes connected by welding or the like, or can be an integrally formed component, thereby forming a closed or open rectangle, oval, circle or the like configuration. The insertion seat 2120 can be connected and fastened with the seat frame 2110 by the first fastener 2130 such as a screw. The insertion seat 2120 can also be fixedly connected with the seat frame 2110 by splicing, welding or the like, but the present disclosure is not limited thereto. As shown in FIGS. 24 and 26, the locking insert 2121 can be provided on the insertion seat 2120. The locking insert 2121 can be provided on the surface of the insertion seat 2120 engaged with the connecting seat 2210. In an embodiment, the insertion seat 2120 is inserted into the connecting seat 2210 along a substantially front-rear direction. For stability and aesthetics, the insertion seat 2120 and the connecting seat 2210 can have complementary engagement surfaces, so that they can be tightly fitted together after being inserted in place. The locking insert 2121 can extend rearward from the insertion seat 2120. The insertion slot 2211 of the connecting seat 2210 is positioned corresponding to the position of the locking insert 2121, and is optionally provided on the surface of the connecting seat 2210 engaged with the insertion seat 2120. In an embodiment, the insertion slot 2211 can be open toward the front side of the child seat 20, for the locking insert 2121 to be inserted thereinto from front to rear. It can be understood that in another embodiment, the insertion slot 2211 can be open toward the rear side of the child seat 20 or other directions, and the locking insert 2121 can extend forward or other corresponding directions from the insertion seat 2120 to be inserted into the insertion slot 2211 in the front direction or other corresponding directions. Optionally, the insertion seat 2120 has an arc-shaped insertion surface 2129 concave inward, and the connecting seat 2210 has an arc-shaped mating surface 2218 convex outward corresponding to the arc-shaped insertion surface 2129. The arc-shaped insertion surface 2129 can have a first concave section 2129a facing rearward and a second concave section 2129b facing downward. The locking insert 2121 can extend rearward from the first concave section 2129a of the arc-shaped insertion surface 2129. Accordingly, the arc-shaped mating surface 2218 convex outward can have a first convex section 2218a facing forward and a second convex section 2218b facing upward. The insertion slot 2211 can be provided on the first convex section 2218a of the arc-shaped mating surface 2218.When the insertion seat 2120 is inserted into the connection seat 2210 and positioned in place, the locking insert 2121 is inserted into the insertion groove 2211, and the arc-shaped insertion surface 2129 is matched with the arc-shaped matching surface 2218, so that the insertion seat 2120 and the outer surface of the connection seat 2210 are closely connected and flush. The specific structure of the locking insert 2121 and the insertion groove 2211 will be described in detail later. In this embodiment, the first inner recessed section 2129a and the first outer convex section 2218a are inclined with respect to the vertical direction, and the second inner recessed section 2129b and the second outer convex section 2218b are substantially parallel to the horizontal direction. In other embodiments, the first inner recessed section 2129a and the first outer convex section 2218a can also be substantially parallel to the vertical direction. Or in other embodiments, the second inner recessed section 2129b and the second outer convex section 2218b can also be inclined with respect to the horizontal direction. The rocker 2220 can also include a rocker operating member 2221 and a clamping hole 2223 provided on the inner side of the rocker 2220 for receiving the support rod 2230. The two ends of the support rod 2230 can be provided with a first reset member 2231, so that the rocker 2220 and the support rod 2230 are connected and fastened, and the rocker operating member 2221 is used to switch the rocker 2220 and the support rod 2230 from the locked state of connection and fastening to the disassembled state of separation from each other. The two ends of the support rod 2230 can be detachably connected with the rocker 2220, which will be described in detail later. Referring to FIG. 25, a side view schematic diagram of the child seat 20 in a stationary state on a support surface is shown. The insertion seat 2120 and the connection seat 2210 extend along a first direction, which is at an angle a with respect to the vertical direction perpendicular to the support surface, and the angle a can be between 10° and 45°, which is beneficial to keep the child seat 20 in a low front and high back posture in a stationary state after being installed in place. The seat frame 2110 of the seat assembly 2100 is at an angle B with respect to the front-back direction, which is optionally between 10° and 45°, so that the child can comfortably lie in the child seat 20. Preferably, in an embodiment, after the seat assembly 2100 and the chassis assembly 2200 are installed in place, the connection seat 2210 and the insertion seat 2120 as a whole present a posture of extending obliquely upward and forward, and the seat frame 2110 presents an oblique posture of low front and high back. It can also be said that the connection between the insertion seat 2120 and the seat assembly 2110 and the connection between the connection seat 2210 and the rocker 2220 are staggered with respect to the front-back direction.For example, the connection position of the docking seat 2120 and the seat assembly 2110 can be more forward than the connection position of the docking seat 2210 and the rocker 2220. Such an arrangement can allow the seat assembly 2100 to have a forward low and rear high reclining position for use by a baby or a child, and can also ensure that the seat assembly 2100 has a stable support. Preferably, in an embodiment, the angle 9 between the front side of the docking seat 2120 and the extension plane of the seat frame 2110 is an acute angle. Since the connection between the docking seat 2120 and the seat frame 2110 is close to the longitudinal front portion of the seat frame 2110, such an arrangement can prevent excessive shear stress on the docking seat 2120 when the seat assembly 2100 is in use, thereby improving the overall service life of the child seat 20. The seat assembly 2100 can be docked to the chassis assembly 2200 along a second direction, which is transverse to the first direction. Optionally, the second direction is parallel to the front-rear direction of the child seat 20, in which case the acute angle between the first direction and the second direction is between 45° and 80°. Of course, the second direction can also be at an angle to the front-rear direction, for example, the acute angle between the first direction and the second direction is between 0° and 45°, and the present disclosure is not limited in this respect. When the child seat 20 is in a stationary state, the front-rear direction projection length of the seat frame 2110 on the support surface can be slightly less than the front-rear direction projection length of the two rockers 2220 on the support surface, which is beneficial to the overall stability of the child seat 20. Referring to FIG. 26, the locking insert 2121 can extend from the docking seat 2120 along the second direction. Specifically, the locking insert 2121 can extend outward from the arc-shaped docking surface 2129 along the second direction. Optionally, the locking insert 2121 can extend from the docking seat 2120 along the front-rear direction, or the extension direction of the locking insert 2121 can be at an angle to the front-rear direction. In an embodiment, the locking insert 2121 can include a locking protrusion 2122 extending from the body of the locking insert 2121. The locking protrusion 2122 can have a limiting portion 2123 at the extension site where the locking protrusion 2122 meets the body, for engaging and locking with the corresponding engagement structure, which will be described in detail below. In an embodiment, the locking insert 2121 can also include an arm 2124, and the locking protrusion 2122 can be disposed at the end of the arm 2124 and have an extension site with an enlarged size from the end. The extension site is formed, for example, by having an enlarged size in the first direction. The locking protrusion 2122 can have a limiting portion 2123 at the extension site where the locking protrusion 2122 meets the arm 2124. The arm 2124 extends from the docking seat 2120 and along the second direction.Due to the elongated shape of the arm 2124, it has a certain elastic deformation, so that when the locking insert 2121 is inserted into the insertion slot 2211, the arm 2124 can elastically deform to provide relief if necessary. In an embodiment, the locking insert 2121 can further include a locking portion 2125, and the locking portion 2125 can further be provided with a first clamping hole 2126a and a second clamping hole 2126b for clamping locking with the corresponding clamping structure, which will be described in detail below. Referring to FIG. 27, it shows a perspective view of the chassis assembly 2200. The connecting seat 2210 can include an outer cover 2210a arranged on the outer side in the transverse direction and an inner cover 2210b arranged on the inner side. The outer cover 2210a is provided with a button slot 2213 opening outwardly - in the example shown in FIG. 27, the button slot 2213 is arranged on the outer side of the outer cover 2210a in the transverse direction, so as to facilitate the operation of the button. The release operating member 2240 can be arranged on the connecting seat 2210 and at least partially accommodated in the button slot 2213 - specifically, as shown in FIG. 28, the internal structure of the connecting seat 2210 after the inner cover 2210b is removed, in an embodiment, the release operating member 2240 can include a pivot shaft 2242 and an operating portion 2241 and a clamping portion 2244 located on both sides of the pivot shaft 2242. The portion of the operating portion 2241 exposed to the outside of the outer cover 2210a can be formed in a rectangular, oval or other shape, which can optionally be provided with a corrugated or anti-slip coating, so as to facilitate the user to press and operate. The size and shape of the operating portion 2241 can match the size and shape of the button slot 2213, so as to be fitted in the button slot 2213. The operating portion 2241 and the clamping portion 2244 can be located on the front and rear sides of the pivot shaft 2242, respectively. The clamping portion 2244 can be provided with a first clamping member 2244a and a second clamping member 2244b in the second direction. The first clamping member 2244a and the second clamping member 2244b can be formed as hook-shaped lugs protruding towards the locking insert 2121 inserted into the insertion slot 2211 of the connecting seat 2210. The first clamping member 2244a and the second clamping member 2244b can respectively have inclined surfaces inclined from the inside of the connecting seat 2210 towards the outside of the connecting seat 2210 in the second direction, so as to engage with the first clamping hole 2126a and the second clamping hole 2126b of the locking insert 2121 in the locked state, and disengage from the engagement with these clamping holes in the release state. This will be described in detail below.The interior of the connecting seat 2210 can also be formed with reinforcing ribs 2216 and guide ribs 2217. The reinforcing ribs 2216 can reinforce the structural strength of the connecting seat 2210, and the guide ribs 2217 can limit and guide the release operating member 2240 and the locking insert 2121 in addition to reinforcing the structural strength of the connecting seat 2210. The pivot shaft 2242 is located in the pivot slot 2212 defined by the guide ribs 2217, and can rotate in the pivot slot 2212. The axial direction of the pivot shaft 2242 can be arranged along the first direction, or other directions, which are not limited in the present disclosure. Thus, by applying a pressing force to the operating part 2241 towards the lateral inner side, the clamping part 2244 can be pivoted towards the outer movement around the pivot shaft 2242, so that the first clamping part 2244a and the second clamping part 2244b of the clamping part 2244 can be disengaged from the first clamping hole 2126a and the second clamping hole 2126b of the locking insert 2121. In an embodiment, the outer cover 2210a can be provided with a plurality of connecting posts 2214. The connecting posts 2214 can be arranged at any position of the outer cover 2210a according to the structural layout requirements inside the connecting seat 2210, and can be optionally arranged at the edge or the central position of the outer cover 2210a. In an embodiment, the connecting posts 2214 can be distributed along the edge of the outer cover 2210a. The connecting posts 2214 can extend away from the inner surface of the outer cover 2210a along a direction perpendicular to the inner surface of the outer cover 2210a. In the present embodiment, the connecting posts 2214 are hollow cylindrical structures. It can be understood that the connecting posts 2214 can also be solid cylinders. Referring to FIGS. 29-30, the structural and connecting relationship of the plug-in seat 2120, the connecting seat 2210, and the release operating member 2240 according to an embodiment of the present disclosure is specifically shown, wherein the locking insert 2121 of the plug-in seat 2120 and the release operating member 2240 constitute a clamping and dismounting structure. FIGS. 29 and 30 respectively show the corresponding changes of the clamping and dismounting structure when the child seat 20 is in the locked state and the released state. In an embodiment, the release operating member 2240 can also include a second reset part 2243. One end of the second reset part 2243 is connected to the clamping part 2244, and the other end can be fixed to a position inside the connecting seat 2210. The second reset part 2243 applies an elastic force to the clamping part 2244, so that the release operating member 2240 has a tendency to keep the clamping part 2244 in the locked position where the clamping holes of the locking insert 2121 are clamped with each other. The second reset part 2243 can be a coil spring, a leaf spring, or other elastic parts.In FIG. 29, the child seat 20 is in a locked state. In an embodiment, the locking insert 2121 is inserted into the connecting seat 2210 along the second direction (i.e., moving rearward) through the insertion slot 2211, the first engaging hole 2126a of the locking insert 2121 first engages with the second engaging member 2244b of the engaging portion 2244, the locking insert 2121 is further pushed inward, the first engaging hole 2126a disengages from the second engaging member 2244b and continues to move into the connecting seat 2210 until the locking portion 2125 abuts against the guide rib 2217, so that the locking insert 2121 cannot move along the second direction rearward. At this time, the first engaging hole 2126a engages with the first engaging member 2244a, and the second engaging hole 2126b engages with the second engaging member 2244b, so that the locking insert 2121 cannot move along the second direction forward, thereby cannot disengage from the connecting seat 2210. The locking insert 2121 cannot move along the second direction by the engagement of the first engaging hole 2126a and the second engaging hole 2126b with the first engaging member 2244a and the second engaging member 2244b of the engaging portion 2244 and the abutment of the locking portion 2125 and the guide rib 2217, thereby cannot disengage from the connecting seat 2210. It can be understood that only one engaging hole or more than two engaging holes can be provided, and corresponding engaging members can be provided. It can also be understood that the number of engaging holes and engaging members can be inconsistent. The insertion slot 2211 can also limit the downward movement of the locking insert 2121. In addition, the sliding along the insertion direction or the upward and downward movement of the locking insert 2121 can be limited by designing corresponding guide ribs 2217 in the connecting seat 2210. When the child seat 20 is in the locked state, the release operating member 2240 is always subjected to the force applied by the second return member 2243, the first engaging member 2244a and the second engaging member 2244b can remain engaged with the first engaging hole 2126a and the second engaging hole 2126b, thereby keeping the locking insert 2121 in the position engaged with the release operating member 2240. In FIG. 30, the child seat 20 is in an unlocked state. In an embodiment, the operating portion 2241 of the release operating member 2240 is pressed, the operating portion 2241 moves toward the inside of the connecting seat 2210 around the pivot shaft 2242, and the engaging portion 2244 is moved toward the outside of the connecting seat 2210 against the force applied by the second return member 2243 until the first engaging member 2244a and the second engaging member 2244b disengage from the engagement with the first engaging hole 2126a and the second engaging hole 2126b. Thus, the locking insert 2121 disengages from the engagement with the release operating member 2240.At this time, the locking insert 2121 can move out of the connection seat 2210o in a second direction (i.e., forward movement) along the insertion slot 2211. FIG. 31 is a side view schematic diagram of the chassis assembly 2200 according to an embodiment of the present disclosure, which shows the internal structure of the connection seat 2210. The connection seat 2210 can be connected and fastened with the rocker 2220 by a second fastener 2250, such as a screw. The connection seat 2210 can also be fixedly connected to the rocker 2220 by brazing, welding, etc., or be integrally formed with the rocker 2220, but the present disclosure is not limited thereto. In particular, FIG. 31 also shows a welding structure. The welding structure can include a connecting column 2214 and a sleeve 2215. The inner cover 2210b can be provided with a plurality of sleeves 2215, which can correspond to the connecting column 2214 on the outer cover 2210a of the connection seat 2210. In an embodiment, the sleeves 2215 can be evenly distributed along the edge of the inner cover 2210b.

[0004] The sleeve 2215 can extend away from the inner surface of the inner cover 2210b in a direction perpendicular to the surface of the inner cover 2210b. The sleeve 2215 can be formed in a hollow cylindrical shape. The connecting column 2214 can be inserted into the sleeve 2215 in an interference fit manner, so that the inner cover 2210b and the outer cover 2210a can be fixed together by buckling. A plurality of welding ribs or welding bumps can also be additionally provided on the inner side surface of the sleeve 2215 to fix the inner cover 2210b and the outer cover 2210a together, but the present disclosure is not limited thereto. By the cooperation of the connecting column 2214 and the sleeve 2215, the welding energy consumption can be greatly reduced while ensuring the welding strength. It can be understood that the sleeve can also be provided on the outer cover 2210a, and the connecting column 2214 is correspondingly provided on the inner cover 2210b to achieve the buckling and fixing of the outer cover 2210a and the inner cover 2210b. It can be understood that the buckling and fixing between the connecting column 2214 and the sleeve 2215 of the present disclosure can also be replaced or additionally fixed by using screws, nuts, welding and other known fixing methods. FIG. 31 also shows a support rod dismounting structure. The support rod dismounting structure can include a rocker operating piece 2221 and a support rod 2230. The rocker operating piece 2221 can be arranged in a mounting groove 2222 on the top surface of the rocker 2220. The outer surface of the rocker operating piece 2221 is substantially flush with or slightly lower than the top surface of the rocker 2220, so that the overall appearance of the child seat 20 is more beautiful, and at the same time, improper operation caused by accidental contact of the user can be prevented. The inner surface of the rocker operating piece 2221 facing the mounting groove 2222 can have a protrusion 2228 for abutting against a first reset piece 2231 on the support rod 2230. The rocker operating piece 2221 will be deformed and displaced downward after being pressed downward, and can return to the original position after the pressing force disappears. The rocker operating piece 2221 can be a leaf spring or other elastic member, but the present disclosure is not limited thereto. The support rod 2230 can be formed as a rod member with a non-circular cross section, and the size and shape of the clamping hole 2223 of the rocker 2220 for receiving the support rod 2230 are matched with the support rod 2230. In an embodiment, the cross-sectional profile of the support rod 2230 can be formed in a shape composed of an arc and a chord, so as to facilitate the alignment of the support rod 2230 with the clamping hole 2223 when the support rod 2230 is installed to the rocker 2220 and cannot rotate relative to the clamping hole 2223 after the installation is completed. The cross-sectional profile of the support rod 2230 is not limited thereto, and can also have a reverse triangular shape, a rectangular shape, an elliptical shape, a hexagonal shape, etc. The first reset piece 2231 can be an elastic pin or an elastic body made of an elastic material, but the present disclosure is not limited thereto, which can move between the circumferential wall of the support rod 2230 and the protrusion and the retraction.The top of the circumferential wall of the clamping hole 2223 can be provided with a clamping hole groove 2229 for accommodating the first reset member 2231 protruding out of the circumferential wall of the support rod 2230. When the two ends of the support rod 2230 are inserted into the clamping holes 2223 of the rocker 2220, the first reset member 2231 at the two ends of the support rod 2230 is constrained by the inner circumferential wall of the clamping hole 2223 and can be retracted inward against the elastic force until the support rod 2230 is inserted to a predetermined position in the clamping hole 2223, at which time the first reset member 2231 is located at the clamping hole groove 2229, the constraint of the first reset member 2231 by the inner circumferential wall of the clamping hole 2223 disappears, and the first reset member 2231 extends into the clamping hole groove 2229 under the action of the elastic force, thereby clamping and connecting the support rod 2230 and the rocker 2220. It can be understood that the first reset member 2231 can be replaced by one or more reset elements with reset function, which will not be described here. If the support rod 2230 and the rocker 2220 are to be disassembled, the user can press the rocker operating member 2221 downward, the protrusion 2228 moves downward accordingly, the protrusion 2228 abuts against the first reset member 2231 to retract it into the support rod 2230, thereby moving the first reset member 2231 out of the clamping hole groove 2229. At this time, the support rod 2230 and the rocker 2220 are disengaged from the clamping, and then the support rod 2230 can be pulled out of the clamping hole 2223, so that the support rod 2230 and the rocker 2220 are disconnected. Thus, the chassis assembly 2200 can be disassembled, and the support rod 2230 and the rocker 2220 can be packaged or stored separately, so as to facilitate transportation or storage. Referring to FIG. 32, a perspective view of installing the seat assembly 2100 of the child seat 20 according to one or more embodiments described above to a high chair 2300 according to another embodiment of the disclosure is shown. The user can disassemble the seat assembly 2100 and the chassis assembly 2200 of the child seat 20 according to one or more embodiments described above, and install the seat assembly 2100 on the high chair 2300 to form a child seat 20 with a certain height, which is convenient for the caregiver to feed the child. It can be understood that the seat assembly 2100 can also be installed on other carrier or support assemblies, which is not limited in the present application. Referring to FIG. 33, the clamping and disassembly structure of the seat assembly 2100 and the high chair 2300 is shown. The high chair 2300 can include a first leg 2310, a second leg 2320, an arm 2330, and a connecting seat 2340. The connecting seat 2340 can be provided at the joint of the first leg 2310 and the arm 2330. When the seat assembly 2100 is installed on the high chair 2300, the insertion seat 2120 and the connecting seat 2340 are connected by the clamping and disassembly structure.The following only describes the differences between the engagement and disengagement structure of the present embodiment and the above-described embodiments, and the same or similar parts will be omitted. The locking insert 2121 is inserted into the connecting seat 2340 along the second direction through the insertion slot 2341. When entering the insertion slot 2341, the support arm 2124 can be elastically deformed to displace upward to provide a clearance, so that the locking protrusion 2122 can enter the insertion slot 2341 more smoothly, and when the locking insert 2121 reaches a predetermined position in the connecting seat 2340, the support arm 2124 can be elastically deformed to return to the original position, and the locking protrusion 2122 is displaced downward, so that the limiting portion 2123 is engaged with the limiting step 2342 on the first leg 2310. The side wall of the connecting seat 2340 can guide and limit the locking insert 2121. In an embodiment, a stop portion 2343 can be further formed in the connecting seat 2340, which can limit the locking portion 2125 together with the side wall of the connecting seat 2340. The abutting portion 2127 of the locking insert 2121 abutting against the stop portion 2343 can limit the locking insert 2121 in the second direction, but the abutting portion 2127 can move up and down without being limited by the stop portion 2343, and when the locking insert 2121 reaches the fully inserted position, the locking protrusion 2122 can be arranged outside the high chair 2300. In an embodiment, in order to separate the seat assembly 2100 from the high chair 2300, an upward force is applied to the locking protrusion 2122 exposed outside the high chair 2300. The force bends the locking protrusion 2122 towards the locking portion 2125, so that the limiting portion 2123 is disengaged from the limiting step 2342, thereby facilitating the separation of the seat assembly 2100 from the high chair 2300. The term "about" is intended to include the degree of error associated with measurement of the particular quantity based upon the equipment available at the time of filing the application. FIGS. 34-47 schematically show several embodiments and variations of the present disclosure, but they are merely used to illustrate the technical concept of the present disclosure, and are not used to limit the protection scope of the present disclosure. Referring to FIGS. 34 and 35, they show perspective views of a child rocker 30 in an embodiment of the present disclosure, wherein the child rocker 30 is in a mounted state. Specifically, FIG. 34 shows the child rocker 30 viewed from the front. The child rocker 30 can include a seat assembly 3100 and a chassis assembly 3200 supporting the seat assembly 3100 - the seat assembly 3100 is used to support and mount a seat or a seat cloth, so as to place a child on the seat or the seat cloth for rocking entertainment. The seat assembly 3100 can be mounted above or directly above the chassis assembly 3200.The seat assembly 3100 can include a seat frame 3110 and a socket 3120, wherein the seat frame 3110 can be used to support and mount a seat or a seat cloth. The seat frame 3110 can be located above the socket 3120. The seat frame 3110 can be formed by connecting a plurality of tubes by welding or the like, or can be integrally formed, thereby forming a closed or open rectangle, an ellipse, a circle, etc. The seat frame 3110 can be fixedly connected to the socket 3120 by brazing, welding, or the like, or the two can be integrally formed, but the present disclosure is not limited thereto. The socket 3120 extends from the seat frame 3110 toward the chassis assembly 3200, in other words, downward along the first direction. The width of the upper surface of the socket 3120 is optionally matched with the width of the lower surface of the seat frame 3110. The socket 3120 can be fixed at a position slightly lower in the longitudinal direction of the seat frame 3110 on both sides of the seat frame 3110, so as to facilitate the overall forward-leaning posture of the child rocker 30 in a stationary state. For example, the midpoint of the connection position of the socket 3120 and the seat frame 3110 is within the range of 1 / 4-1 / 2 of the length of the seat frame 3110. The chassis assembly 3200 can include a connecting seat 3210, a rocker 3220, and a support rod 3230. Two rockers 3220 can be respectively arranged on the left and right sides of the child rocker 30. Each rocker 3220 can be an arc-shaped rod, so as to realize forward and backward rocking after being placed on the ground. The connecting seat 3210 can be located above the rocker 3220. The connecting seat 3210 can be fixedly connected to the rocker 3220 by brazing, welding, or the like, or can be integrally formed with the rocker 3220, but the present disclosure is not limited thereto. The width of the lower surface of the connecting seat 3210 is optionally matched with the width of the upper surface of the rocker 3220. The connecting seat 3210 can extend from the upper surface of the rocker 3220 toward the seat assembly 3100, in other words, also upward along the first direction. The connecting seat 3210 can be fixed at a position substantially in the middle in the longitudinal direction of the rocker 3220. For example, the midpoint of the connection position of the connecting seat 3210 and the rocker 3220 is within the range of 1 / 3-1 / 2 of the length of the rocker 3220. Optionally, the first direction forms an angle a with the vertical direction, the angle a is between 10°-45° (see FIGS. 44A-44B), which is conducive to maintaining the forward-leaning posture of the child rocker 30 in a stationary state after being installed in place. The support rod 3230 can be arranged between the two rockers 3220 located on both sides of the child rocker 30, and the two ends of the support rod 3230 are fixedly connected with the rockers 3220, respectively.The support rods 3230 can be provided as one, two or more, which can be selected according to the firmness of the chassis assembly 3200. The seat frame 3110 of the seat assembly 3100 is at an angle B with the front-rear direction, which is optionally between 10°-45° (see FIGS. 39A-39B), so that the child can lie comfortably on the back in the child rocker 30. Preferably, after the seat assembly 3100 and the chassis assembly 3200 are installed in place, the docking seat 3120 and the connecting seat 3210 are presented as extending upwardly inclined in the direction from back to front, while the seat frame 3110 is presented as extending downwardly inclined. It can also be said that the connection between the docking seat 3120 and the seat assembly 3110 and the connection between the connecting seat 3210 and the rocker 3220 are staggered with each other in the front-rear direction. Such a setting can make the seat assembly 3100 have a downwardly inclined orientation suitable for infant use on the one hand, and better support on the other hand. Preferably, in an embodiment, the front side of the connection between the docking seat 3120 and the seat frame 3110 is at an acute angle, or the front side of the upper end of the docking seat 3120 is at an acute angle with the seat frame 3110. As shown in FIGS. 44A-44B, since the connection between the docking seat 3120 and the seat frame 3110 is close to the longitudinal front part of the seat frame 3110, such a setting makes the seat assembly 3100 not cause excessive shear stress on the docking seat 3120 when in use, thereby improving the overall service life of the child rocker 30. The seat assembly 3100 and the chassis assembly 3200 are detachably connected through the snap-on and detach structure between the docking seat 3120 and the connecting seat 3210. Specifically, the seat assembly 3100 can be docked to the chassis assembly 3200 along a second direction, as shown in FIGS. 39A-39C, the second direction is staggered with the first direction. Optionally, the second direction is parallel to the front-rear direction of the child rocker 30, at this time, the acute angle between the second direction and the first direction is between 45°-80°. Of course, the second direction can also be at an angle with the front-rear direction, for example, the acute angle between the second direction and the first direction is between 0°-30°, the present disclosure is not limited thereto. The lower surface shape of the docking seat 3120 is optionally matched with the upper surface shape of the connecting seat 3210. When the docking seat 3120 is docked to the connecting seat 3210, the circumferential wall part of the docking seat 3120 is flush with the circumferential wall part of the connecting seat 3210, so that the product is more beautiful.The child swing 30 in the static state, the seat frame 3110 in the horizontal plane on the front and back direction projection length can be slightly smaller than the rocker 3220 in the horizontal plane on the front and back direction projection length (see FIGS. 39A-39B, 44A-44B, 45A-45C), the seat frame 3110 in the horizontal plane on the transverse projection length can be equal to, slightly smaller than or slightly larger than the rocker 3220 in the horizontal plane on the transverse projection length (see FIGS. 34-35), which is beneficial to the overall stability of the child swing 30. FIG. 35 shows the child swing 30 from the back. In an embodiment, the connecting seat 3210 is provided with a release operation member 3240 on the back of the longitudinal rear side. The release operation member 3240 can be arranged in the outward opening button groove 3213 of the connecting seat 3240. The release operation member 3240 can be located at about the middle position of the back of the connecting seat 3210 in the vertical direction, so as to facilitate the operation of the user. The child swing 30 in the locked state, the outer surface of the release operation member 3240 is substantially flush with the outer surface of the connecting seat 3210 (see FIGS. 39A, 44A-44B, 45A-45C), so that the overall appearance of the child swing 30 is more beautiful, and at the same time can prevent improper operation caused by accidental touch of the user. In other embodiments, the release operation member 3240 can be arranged at other positions. Referring to FIGS. 36-37, which show the child swing 30 in the disassembled state according to an embodiment of the present disclosure. The locking insert 121 is arranged on the plug-in seat 3120 and fixedly connected with the plug-in seat 3120. The locking insert 121 can be arranged on the surface of the plug-in seat 3120 and the connecting seat 3210. The locking insert 121 can extend from the plug-in seat 3120 in the second direction, optionally in the front and back direction, or the extension direction thereof can be at an angle to the front and back direction. The locking insert 121 can be provided with a locking protrusion 31211. In an embodiment, the locking insert 121 can include a locking protrusion 31211 extending from the body of the locking insert 121. The locking protrusion 31211 can form a limiting portion 31212 at the extension position thereof connected with the body, and the limiting portion 31212 can be clamped with the limiting step 3251 of the locking piece 3250 (see FIG. 39A), which will be described in detail below. The insertion groove 3211 is arranged corresponding to the position of the locking insert 121, and is optionally arranged on the surface of the connecting seat 3210 engaged with the plug-in seat 3120. In an embodiment, the insertion groove 3211 can be opened towards the front side of the child swing 30, so as to insert the locking insert 121 therein in the rearward direction.As can be appreciated, in another embodiment, the insertion slot 3211 can be opened toward the rear side of the child rocker 30 or in other directions for the locking insert 121 to be inserted in the forward direction or in other directions. Optionally, the locking insert 121 can further include an arm 31213, and the locking protrusion 31211 is disposed at the end of the arm 31213, and the locking protrusion 31211 can form a limiting portion 31212 at the extension part where the arm 31213 is connected to the locking protrusion 31211. The arm 31213 extends from the insertion base 3120 and extends in the second direction. Since the arm 31213 is elongated and has a certain deformation elasticity, when the locking insert 121 is inserted into the insertion slot 3211, the arm 31213 can elastically deform to provide relief when necessary, so that the locking protrusion 31211 can be more smoothly engaged with the limiting step 3251. Optionally, in some embodiments, the locking insert 121 can further include an additional locking portion 31214, and the additional locking portion 31214 can be further provided with an engagement hole 31215 for engaging with the locking structure of other structures, so that the seat assembly 3100 can be mounted and locked with other structures to increase the versatility of the seat assembly 3100. Optionally, the insertion base 3120 has an arc-shaped insertion surface 3122 concave inward, and the connecting base 3210 has an arc-shaped mating surface 3218 convex outward corresponding to the arc-shaped insertion surface 3122. When the insertion base 3120 is inserted into the connecting base 3210, the arc-shaped insertion surface 3122 cooperates with the arc-shaped mating surface 3218, so that the surface of the insertion base 3120 and the connecting base 3210 are flush. The locking insert 121 extends outward in the second direction from the arc-shaped insertion surface 3122. Referring to FIGS. 38 and 39A-39C, the structure and connection relationship of the insertion base 3120, the connecting base 3210, the unlocking operation member 3240, and the locking member 3250 according to an embodiment of the disclosure are specifically shown, wherein the locking insert 121 of the insertion base 3120, the unlocking operation member 3240, and the locking member 3250 constitute an engagement and disassembly structure. FIGS. 39A, 39B, and 39C respectively show the corresponding changes of the engagement and disassembly structure when the child rocker 30 is in the locked state, the unlocked state, and the disassembled state. Specifically, as shown in FIG. 38, in an embodiment, the unlocking operation member 3240 can include an operation portion 3241, a connecting rod 3242, and a driving protrusion 3244. The outward plane of the operation portion 3241 can be rectangular or oval or other shapes, and can be provided with corrugations or anti-slip coatings to facilitate user pressing operation. The operation portion 3241 and the driving protrusion 3244 can be respectively disposed at the two ends of the connecting rod 3242.The linkage rod 3242 can extend longitudinally from the bottom of the operation portion 3241, and can be formed as a rectangular rod. The driving protrusion 3244 can extend transversely from the end of the linkage rod 3242 away from the operation portion 3241, and can be formed as a cylindrical protrusion. The lock matching member 3250 can include a driving inclined slot 3252 that cooperates with the driving protrusion 3244, and the driving inclined slot 3252 can be an elongated slot. Thus, by applying a force to the operation portion 3241, the linkage rod 3242 can be driven to slide along a second direction, thereby driving the driving protrusion 3244 to slide relative to the driving inclined slot 3252, and further driving the lock matching member 3250 to move along a third direction between the locked position and the unlocked position, the third direction being different from the second direction. Optionally, the unlocking operation member 3240 can further include a restoring member 3243. One end of the restoring member 3243 can be connected to the operation portion 3241, and the other end can be connected to a corresponding position in the connecting base 3210. The restoring member 3243 can apply an elastic force to the operation portion 3241, so that the unlocking operation member 3240 has a tendency to keep the lock matching member 3250 in the locked position. The restoring member 3243 can be a coil spring, a leaf spring, or other elastic member. In the present embodiment, the lock matching member 3250 moves in a linear manner along the third direction, and the third direction is transverse to the second direction. In other embodiments not shown, the lock matching member 3250 can switch between the locked position and the unlocked position in a non-linear manner along the third direction (e.g., clockwise or counterclockwise). In other embodiments not shown, the unlocking operation member 3240 can not include the linkage rod 3242, so that one side of the operation portion 3241 is formed with the driving protrusion 3244, so that applying a force to the operation portion 3241 can directly drive the driving protrusion 3244 to slide relative to the driving inclined slot 3252. At this time, the restoring member 3243 can be connected between the connecting base 3210 and the lock matching member 3250, and directly apply an elastic force to the lock matching member 3250, so that the lock matching member 3250 has a tendency to be kept in the locked position. As shown in FIG. 38 and FIGS. 39A-39C, in an embodiment, the connecting base 3210 is formed with a button slot 3213, and the position of the button slot 3213 is opposite to the position of the insertion slot 3211 in the longitudinal direction. In an embodiment, the button slot 3213 can be located on the back of the connecting base 3210. The size and shape of the button slot 3213 can match the size and shape of the operation portion 3241.The interior of the connecting seat 3210 is also formed with guide ribs 3217, which can not only strengthen the structural strength of the connecting seat 3210, but also limit and guide the release operating member 3240, the matching member 3250, and the locking insert 121 (see FIGS. 38, 39A-39C, 40-41, 45A-45C). FIGS. 39A-39C show the connection and relative movement relationship of the connecting seat 3210, the release operating member 3240, the matching member 3250, and the locking insert 121. The matching member 3250 is slidably arranged in the release operating member 3240, so that the release operating member 3240 can drive the matching member 3250 to slide in the connecting seat 3210, so that the matching member 3250 can move between the locked position of engaging with the locking insert 121 and the release position of disengaging from the locking insert 121. In an embodiment, the matching member 3250 can be slidably arranged in the interior of the connecting seat 3210 through the guide ribs 3217 on the inner surface of the connecting seat 3210, and the guide ribs 3217 can also limit the matching member 3250. Specifically, the matching member 3250 can slide along the third direction by means of the fifth guide rib 32175, the seventh guide rib 32177, and the eighth guide rib 32178, and the third guide rib 32173 and the sixth guide rib 32176 limit or support the matching member 3250 on the upper side and the lower side of the sliding direction thereof, respectively. In some embodiments, optionally, the matching member 3250 further comprises a limiting groove 3253, which can also be an elongated groove. The limiting groove 3253 is arranged along the sliding direction of the matching member 3250, that is, extends along the third direction. The limiting groove 3253 and the extension direction of the driving inclined groove 3252 form an included angle y, which is optionally between 40°-70° (as shown in FIG. 41). Accordingly, the interior of the connecting seat 3210 can also be formed with a limiting protrusion 3212o. The limiting protrusion 3212 can be formed as a boss matching the shape of the limiting groove 3253, and the length of the limiting protrusion 3212 is less than the length of the limiting groove 3253, so that the matching member 3250 can slide along the third direction relative to the limiting protrusion 3212. The limiting groove 3253 of the matching member 3250 can engage with the limiting protrusion 3212, and the matching member 3250 can slide relative to the limiting groove 3253 and the limiting protrusion 3212. Through the cooperation of the limiting groove 3253 and the limiting protrusion 3212, the guiding and limiting effects of the matching member 3250 can be achieved.It can be understood that, in the embodiments of the present disclosure, in order to realize the guiding and limiting of the locking piece 3250, only the limiting groove 3253 and the limiting protrusion 3212 can be arranged, and the guiding rib 3217 for the locking piece 3250 is not arranged; or only the corresponding guiding rib 3217 for the locking piece 3250 can be arranged, and the limiting groove 3253 and the limiting protrusion 3212 are not arranged; of course, both the limiting groove 3253 and the limiting protrusion 3212 and the guiding rib 3217 for the locking piece 3250 can be arranged. The operation part 3241 pushes the connecting rod 3242 to slide in the connecting seat 3210 through the button groove 211, and the driving protrusion 3244 is slidably connected with the driving inclined groove 3252. The operation part 3241 and the connecting rod 3242 can be guided to slide by means of the corresponding rib (such as the fourth guiding rib 32174) in the connecting seat 3210. The locking insert 121 enters the inside of the connecting seat 3210 through the insertion groove 3211, and can be guided to slide by means of the corresponding rib (such as the first guiding rib 32171, the third guiding rib 32173, and the ninth guiding rib 32179) in the connecting seat 3210. In some embodiments not shown in the figures, the locking piece 3250 only includes the limiting groove 3253 and does not include the driving inclined groove 3252. At this time, the release operating piece 3240 is directly formed on one side of the locking piece 3250, and the movement direction of the release operating piece 3240 is the same as the movement direction of the locking piece 3250, that is, both are moved along the third direction. An acting force is applied to the release operating piece 3240, and the release operating piece 3240 directly drives the locking piece 3250 to switch between the locking position and the release position along the third direction. In this case, the reset piece 3243 is directly arranged between the connecting seat 3240 and the release operating piece 3240. In FIG. 39A, the child rocker 30 is in the locked state.At this time, the locking insert 121 is inserted into the connecting seat 3210 through the insertion slot 3211, and the locking protrusion 31211 of the locking insert 121 forms an abutting portion 31216 on the side away from the limiting portion 31212, and the matching abutting portion 3254 of the matching locking piece 3250 is formed on the side away from the limiting step 3251 (as shown in FIG. 38). When the locking insert 121 is inserted into the connecting seat 3210, the abutting portion 31216 of the locking insert 121 abuts against the matching abutting portion 3254 of the matching locking piece 3250, so as to drive the matching locking piece 3250 to move a distance towards the unlocking position to form an avoidance for the locking insert 121, thereby realizing the clamping of the limiting portion 31212 and the limiting step 3251. The locking insert 121 is clamped by the limiting portion 31212 of the locking protrusion 31211 and the limiting step 3251 of the matching locking piece 3250, so that the locking insert 121 cannot move forward along the second direction (i.e., towards the front of the child rocker 30), thereby cannot be separated from the connecting seat 3210. The upper surface of the matching locking piece 3250 can also limit the downward movement of the locking insert 121. In addition, the second guide rib 32172 in the connecting seat 3210 can also limit the locking insert 121 from continuing to slide along the insertion direction (i.e., backward along the second direction) or moving upward and downward. Optionally, the second guide rib 32172 can abut against both the locking protrusion 31211 and the additional locking portion 31214 of the locking insert 121, or the second guide rib 32172 can abut against only one of the locking protrusion 31211 and the additional locking portion 31214 of the locking insert 121. The locking protrusion 31211 is optionally formed as an arc-shaped tab, so as to abut against and slide along the upper surface of the matching locking piece 3250. That is, the abutting portion 31216 is optionally an arc-shaped surface on the locking protrusion 31211, which can abut against and push the matching abutting portion 3254 of the matching locking piece 3250 to move the matching locking piece 3250 towards the unlocking position during the insertion of the locking insert 121 into the connecting seat 3210. The driving protrusion 3244 of the unlocking operating piece 3240 can be in sliding connection with the driving inclined slot 3252 of the matching locking piece 3250, so that the driving protrusion 3244 can slide in the driving inclined slot 3252, and when the child rocker 30 is in the locked state, the unlocking operating piece 3240 is constantly subjected to the force applied by the restoring member 3243, the driving protrusion 3244 can keep abutting against the lower end edge of the driving inclined slot 3252, thereby keeping the matching locking piece 3250 in the clamped position with the locking insert 121.In the embodiment, the first guide rib 32171, the third guide rib 32173, the fourth guide rib 32174, the sixth guide rib 32176 and the ninth guide rib 32179 extend along the second direction; the fifth guide rib 32175, the seventh guide rib 32177 and the eighth guide rib 32178 extend along the third direction. Optionally, in the initial state where the connector 3120 and the connecting seat 3210 are not assembled, or in the locked state of the locking piece 3250, the upper surface of the locking piece 3250 is higher than the upper surface of the ninth guide rib 32179 in the height direction. In this way, when the connector 121 is inserted into the connecting seat 3210, the locking piece 3250 can move away along the third direction and then the limiting portion 31212 and the limiting step 3251 can be connected. Optionally, the upper surface of the ninth guide rib 32179 is arc-shaped near one side of the locking piece 3250, which is beneficial to the exit of the locking connector 121 from the connecting seat 3210 after unlocking. Optionally, similarly, the upper surface of the locking piece 3250 is higher than the upper surface of the third guide rib 32173, specifically, in the initial state where the connector 3120 and the connecting seat 3210 are not assembled, or in the locked state of the locking piece 3250, the upper surface of the locking piece 3250 is higher than the upper surface of the third guide rib 32173 in the height direction. The force is applied to the release operating piece 3240 along the second direction forward, so that the connecting rod 3242 slides along the fourth guide rib 32174 forward, and then the driving protrusion 3244 slides along the driving inclined groove 3252 upward, so that the locking piece 3250 moves downward in the connecting seat 3210 along the third direction, until the locking piece 3250 is separated from the locking connector 121, at this time, the child rocker 30 is in the unlocked state (as shown in FIG. 39B). In the unlocked state, the user can apply a force to the connector 3120 along the second direction to the right, so that the locking connector 121 can move away from the connecting seat 3210 along the second direction, so that the seat assembly 3100 and the chassis assembly 3200 are separated, at this time, the child rocker 30 is in the disassembled state (as shown in FIG. 39C). Then the release operating piece 3240 is released, and the release operating piece 3240 moves backward along the second direction under the action of the reset member 3243, so that the connecting rod 3242 slides backward along the fourth guide rib 32174, and then the driving protrusion 3244 slides along the driving inclined groove 3252 downward, so that the locking piece 3250 moves upward along the third direction, until the locking piece 3250 reaches the locking position of the locking connector 121.Optionally, the side of the latching piece 3250 facing forward along the second direction can abut against an eighth guide rib 32178 in the connecting seat 3210, which can be connected with a ninth guide rib 32179 in the connecting seat 3210 guiding the lower edge of the latching protrusion 31211, wherein at least a portion of the ninth guide rib 32179 is arc-shaped, which is conducive to the latching protrusion 31211 moving away from the connecting seat in the unlocking state. FIGS. 40-43 show the internal structure of the connecting seat 3210 of the child rocker 30 according to an embodiment of the present disclosure, in particular, the welding structure.
