In some cases, the mounting member 1110 is permanently fixed or integrally formed with the bassinet. For example, the mounting member 1110 can be an injection molded piece that is snap-fit onto the bassinet. An example of a mounting member 1110 mounted within a corresponding opening is shown in FIG. 5A. The at least one mounting member 1110 is received within a corresponding 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 first 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 member 1110 with a locking mechanism are shown. As shown, each mounting member 1110 can include a body 1111 having a first end 1111a connectable to the bassinet and a second end 1111b 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 1111b. The primary finger 1113 and the secondary finger 1114 are connected to one another at the first end 1111a of the body 1111, but are separated from one another 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 linear portion and a second arcuate or curved portion arranged at the second end 1111b of the body 1111. However, gaps 1112 having any suitable configuration are contemplated herein. Thus, 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 about 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 the seat member 1210. Outside the seat member 1210, the secondary finger 1114 is no longer restricted by the total height of the openings 1210a, 1220b, and thus can be biased 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 restrict lateral movement of the cradle away from the seat member 1210. To separate the cradle from the seat member 1210, an upward force, illustrated by F1, is applied to the exposed portion of the secondary finger 1114. The force causes the secondary finger 1114 to flex towards the primary finger 1113, aligning the primary finger 1113 and the secondary finger 1114 of the mounting member 1110 with the openings 1210a, 1220b for removal therefrom. The mounting member 1110 can comprise 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 mounted 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 illustrated, the interior of the cradle body 1100 has, for example and without limitation, a soft item or cushioning insert (not shown) disposed therein.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 a rear isometric 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 seating 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 non-limiting embodiments shown, 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 is coupled to a bassinet stand. 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, that typically extends 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 portions 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 as having substantially rounded edges, those skilled in the art will recognize that numerous other designs are available and are 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 horn shape, a rectangle shape, a sphere 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 using a 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,embodiments, the cradle body 1100 can be equipped with a hanging attachment 1120 for holding accessories such as a toy bar, a mobile device (cell phone), a projector, an audio unit, a light bar, or other suitable units. FIG. 15 is a drawing showing an isometric view of an exemplary or representative embodiment of a high chair including a crotch member 1220. FIG. 16 is a drawing showing an isometric view of an exemplary or representative embodiment of a high chair and crotch member 1220 in a disassembled state. FIGS. 17-19 are drawings showing, in plan cross-sectional view, 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 locking. 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 as a result of 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 drawing 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 drawing 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 drawing showing an isometric view of an exemplary or representative high chair embodiment having 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 planar upper surface configured to support an item, 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 the upper surface of the arm pole. Although a portion of the tray 1230 can contact or abut an adjacent surface of the seat member 1210, such as the front of an upstanding side wall, the tray 1230 is not configured to be coupled to or supported by any portion of the seat member 1210. As used herein, the term "coupled" 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 be coupled or attached directly to the arm pole only. Thus, in an embodiment, the tray 1230 cannot be coupled to the high chair when the arm pole 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 a mounted position. In particular, FIG. 23 shows the child seat 20 viewed from a front oblique 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 coupled to the chassis assembly 2200 when the child seat 20 is in a locked state, and the seat assembly 2100 is detachable from the chassis assembly 2200 when the child seat 20 is in an unlocked state. The seat assembly 2100 can support and mount a seat and / or a seat cover to place a child on the seat and / or the seat cover. 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 cover, and a docking base 2120 disposed at a lower side of the seat frame 2110 and mountable 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 elliptical shape, a circular shape, etc. are also possible. The seat frame 2110 can be a one-piece member or can be assembled from multiple parts. Typically, the seat frame 2110 can be a tubular member made of a hollow tube. The seat frame 2110 shown in FIG. 23 is made of a hollow tube having a generally rectangular cross-section,The hollow tube has a flat top surface and a flat bottom surface. The flat top surface can be used to support and mount a seat and / or a seat cloth, and the docking station 2120 can be mounted to the flat bottom surface. The seat frame 2110 thus designed is not only robust 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 station 2120 can extend from the seat frame 2110 (e.g., from the bottom surface of the seat frame 2110) towards 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 on which the child seat 20 is disposed. Here, the “vertical direction” means a direction perpendicular to the support surface (e.g., the ground) on which the child seat 20 is disposed. In this way, the child can be inclinedly seated in the child seat 20 with the head higher than the hips. The width of the upper surface of the docking station 2120 can optionally match the width of the lower surface of the seat frame 2110. The docking station 2120 can be fixed at the lateral sides of the seat frame 2110 at a position slightly lower than the middle of the seat frame 2110 in the longitudinal direction, so as to facilitate the child seat 20 to assume a front-low and rear-high posture in a stationary state. For example, the midpoint of the connection position of the docking station 2120 and the seat frame 2110 can be located in the front 1 / 3-1 / 2 of the longitudinal length of the seat frame 2110, so that the seat assembly 210 can be mounted above the chassis assembly 220 and at a distance from the support surface, so that the seat assembly 210 will not collide with the support surface when the child seat 20 swings forward and backward. 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 backward 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,The width of the bottom surface of the connection seat 2210 can optionally match the width of the top surface of the rocker 2220. The connection seat 2210 can extend from the top surface of the rocker 2220 toward the base frame assembly 2200, in other words, upward along the first direction. The connection seat 2210 can be substantially fixed at a position substantially in the middle of the lengthwise direction of the rocker 2220. For example, the midpoint of the connection position of the connection seat 2210 and the rocker 2220 can be within the range of the first 1 / 3-1 / 2 of the length of the rocker 2220. The support rods 2230 can be provided between the two rockers 2220 on both sides of the child seat 20 so as to increase the overall rigidity of the base frame assembly 2200. The support rods 2230 can be provided in one, two or more, which can be selected according to the specific configuration of the base frame assembly 2200 and the load bearing condition, so as to ensure its firmness and safety. In an embodiment, two support rods 2230 are optionally provided transversely between the two longitudinally extending rockers 2220 in parallel with each other. Alternatively, the two support rods 2230 can be provided between the two rockers 2220 in a non-parallel manner, for example, in a crossing manner. The two ends of the support rods 2230 are respectively connected to the mutually facing inner sides of the two rockers 2220, so that the base frame assembly 2200 is formed as a rigid whole, while ensuring the structural stability of the child seat 20. In an embodiment, the connection seat 2210 can be provided with a release operation member 2240 on the surface toward the transverse outer side. Considering the convenience of operation, the release operation member 2240 can be located substantially at the position close to the upper part of the connection 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 connection 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 provided at other positions. The seat assembly 2100 and the base frame assembly 2200 are detachably connected through the snap-on and detach structure between the insertion seat 2120 and the connection seat 2210. The bottom surface shape of the insertion seat 2120 can match the upper surface shape of the connection seat 2210. Moreover, the shape of the circumferential surface of the insertion seat 2120 can match the shape of the circumferential surface of the connection seat 2210. When the insertion seat 2120 is inserted into the connection seat 2210 so that the seat assembly 2100 and the base frame assembly 2200 are installed in place, the circumferential wall of the insertion seat 2120 is flush with the circumferential wall of the connection seat 2210, so that the product is more beautiful. When the child seat 20 is in a stationary state,The length of the transverse projection of the seat frame 2110 on the horizontal plane can be equal to or slightly less than the length of the transverse projection of the two rocker levers 2220 on the horizontal plane, which is conducive to the overall stability of the child seat 20. Referring to FIG. 24, which 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 connected by a first frame 2111 and a second frame 2112. Optionally, the first frame 2111 and the second frame 2112 are fixedly butted against each other to form a closed-loop seat frame 2110. The first frame 2111 and the second frame 2112 can be left-right symmetrical and butted against each other. The first frame 2111 and the second frame 2112 can optionally be U-shaped, and the two free ends of the U-shapes are butted against 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 process. The small-end interface 2114 can be inserted and fixed in the large-end interface 2113, thereby achieving the fastened assembly of the first frame 2111 and the second frame 2112. The butted 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 large-end interface 2113 and the small-end interface 2114 can be interchanged as needed. In an example, the small-end interface 2114 can be provided with an elastic member and a protruding member (not shown). For example, the elastic member can be a spring sheet fixed in the small-end interface 2114, and the protruding member can be a protrusion provided on the active end of the spring sheet (not shown). The small-end interface 2114 and the large-end interface 2113 are respectively provided with through holes at positions corresponding to the protruding member, so that the protruding member can elastically shuttle between the through holes of the small-end interface 2114 and the large-end interface 2113 when the through holes are aligned. Specifically, when the small-end interface 2114 is inserted into the large-end interface 2113, the protruding member extending from the through hole of the small-end interface 2114 is inwardly retracted against the constraint of the inner wall of the large-end interface 2113 to overcome the elastic force of the elastic member, 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 this time, the protruding piece is inserted into the corresponding through hole of the large end interface 2113 outside the small end interface 2114 under the elastic force of the elastic piece, so that the small end interface 2114 and the large end interface 2113 are clamped and fixedly connected, thereby clamping and fixedly connecting the first frame 2112 and the first frame 2111. If disassembly is required, the protruding piece in the through hole of the large end interface 2113 can be pressed from the outside so that the protruding piece can be retracted into the inside of the small end interface 2114 from the through hole of the large end interface 2113, thereby releasing the clamping and fixation of the protruding piece between the small end interface 2114 and the large end interface 2113. It can be understood that the elastic piece and the protruding piece 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 connected and formed by two or more than two pipes by welding or the like, and can also be an integrally formed component, thereby forming a closed or not closed rectangle, oval, circle or the like configuration. The connector 2120 can be connected and fastened with the seat frame 2110 by the first fastener 2130 such as a screw. The connector 2120 can also be fixedly connected with the seat frame 2110 by welding, soldering or the like, but the present disclosure is not limited thereto. As shown in FIGS. 24 and 26, the locking insert 2121 can be arranged on the connector 2120. The locking insert 2121 can be arranged on the surface of the connector 2120 engaged with the connecting seat 2210. In an embodiment, the connector 2120 is inserted into the connecting seat 2210 along the front and rear directions. For stability and aesthetics, the connector 2120 and the connecting seat 2210 can have complementary engagement surfaces, so that they can be tightly fitted together after being inserted into place. The locking insert 2121 can extend rearward from the connector 2120. The insertion slot 2211 of the connecting seat 2210 corresponds to the position of the locking insert 2121, and is optionally arranged on the surface of the connecting seat 2210 engaged with the connector 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 connector 2120, so as to be inserted into the insertion slot 2211 in the forward direction or other corresponding directions. Optionally,The insertion seat 2120 has an arc-shaped insertion surface 2129 which is concave, and the connection seat 2210 has an arc-shaped matching surface 2218 which is convex and corresponds to the arc-shaped insertion surface 2129. The arc-shaped insertion surface 2129 can have a first concave section 2129a which faces rearward, and a second concave section 2129b which faces downward. The locking insert 2121 can extend rearward from the first concave section 2129a of the arc-shaped insertion surface 2129. Correspondingly, the arc-shaped matching surface 2218 can have a first convex section 2218a which faces forward, and a second convex section 2218b which faces upward. The insertion slot 2211 can be arranged at the first convex section 2218a of the arc-shaped matching surface 2218. When the insertion seat 2120 is inserted into the connection seat 2210 and positioned to the proper position, the locking insert 2121 is inserted into the insertion slot 2211, and the arc-shaped insertion surface 2129 is shaped-fitted with the arc-shaped matching surface 2218, so that the insertion seat 2120 is tightly connected with the outer surface of the connection seat 2210 and flush with it. The specific structure of the locking insert 2121 and the insertion slot 2211 will be described in detail later. In the embodiment, the first concave section 2129a and the first convex section 2218a are inclined relative to the vertical direction, and the second concave section 2129b and the second convex section 2218b are substantially parallel to the horizontal direction. In other embodiments, the first concave section 2129a and the first convex section 2218a can also be substantially parallel to the vertical direction. Or in other embodiments, the second concave section 2129b and the second convex section 2218b can also be inclined relative to the horizontal direction. The rocker 2220 can further include a rocker operating member 2221 and a clamping hole 2223 arranged on the inner side surface of the rocker 2220 for receiving the support rod 2230. The two ends of the support rod 2230 can be provided with first reset members 2231, so that the rocker 2220 is connected and fastened with the support rod 2230, 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. That is, 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 both extend along a first direction which forms an included angle a with the vertical direction perpendicular to the support surface, and the included angle a can be between 10°-45°.This is conducive to the child seat 20 to maintain a low front and high back posture in a static state after installation. The seat frame 2110 of the seat assembly 2100 is at an angle B with the front-back direction, and the angle B is optionally between 10°-45°, so that the child can lie comfortably in the child seat 20. Preferably, in an embodiment, after the seat assembly 2100 and the base assembly 2200 are installed, the connecting seat 2210 and the socket 2120 as a whole present a forward and upward inclined extension state, and the seat frame 2110 presents a low front and high back inclined posture. It can also be said that the connection between the socket 2120 and the seat assembly 2110 and the connection between the connecting seat 2210 and the rocker 2220 are staggered in the front-back direction. For example, the connection position of the socket 2120 and the seat assembly 2110 can be more forward than the connection position of the connecting seat 2210 and the rocker 2220. Such a setting can make the seat assembly 2100 have a low front and high back inclined posture on the one hand to adapt to the use of infants, and on the other hand to ensure that the seat assembly 2100 has a stable support. Preferably, in an embodiment, the angle between the front side of the socket 2120 and the extension surface of the seat frame 2110 is an acute angle. Because the connection between the socket 2120 and the seat frame 2110 is close to the longitudinal front of the seat frame 2110, such a setting makes the seat assembly 2100 not cause excessive shear stress on the socket 2120 when in use, thereby improving the overall service life of the child seat 20. The seat assembly 2100 can be inserted into the base assembly 2200 along a second direction, and the second direction is staggered with the first direction. Optionally, the second direction is parallel to the front-back direction of the child seat 20, and 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-back direction, for example, the acute angle between the second direction and the front-back direction is between 0°-45°. The present disclosure is not limited in this way. The child seat 20 in a static state, the front-back direction projection length of the seat frame 2110 on the support surface can be slightly less than the front-back direction projection length of the two rockers 2220 as a whole on the support surface, which is conducive to the overall stability of the child seat 20. Referring to FIG. 26, the locking insert 2121 can extend from the socket 2120 along the second direction, specifically, the locking insert 2121 can extend outward from the arc-shaped insertion surface 2129 along the second direction. Optionally, the locking insert 2121 can extend from the socket 2120 along the front-back direction, or its extension direction can be at an angle with the front-back direction. In an embodiment,The locking insert 2121 can include a locking protrusion 2122 extending from a body of the locking insert 2121. The locking protrusion 2122 can have a limiting portion 2123 formed at an extended portion thereof adjoining the body, for engaging and locking with a corresponding engaging structure, which will be described in detail below. In an embodiment, the locking insert 2121 can further include an arm 2124, and the locking protrusion 2122 can be disposed at a distal end of the arm 2124, which has an extended portion with an enlarged size. The extended portion can be formed by, for example, enlarging the size in a first direction. The locking protrusion 2122 can have the limiting portion 2123 formed at an extended portion thereof adjoining the arm 2124. The arm 2124 extends from the receptacle 2120 and extends in a second direction. Since the arm 2124 is elongated, 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 clearance if necessary. In an embodiment, the locking insert 2121 can further include a locking portion 2125, which can further have a first engaging hole 2126a and a second engaging hole 2126b, for engaging and locking with a corresponding engaging structure, which will be described in detail below. Referring to FIG. 27, a perspective view of the chassis assembly 2200 is shown. The connecting seat 2210 can include an outer cover 2210a disposed on the outer side in the lateral direction and an inner cover 2210b disposed on the inner side. The outer cover 2210a can have a button slot 2213 opening outwardly. In the example shown in FIG. 27, the button slot 2213 is disposed on the outer side of the outer cover 2210a in the lateral direction, so as to facilitate operation of the button. The release operating member 2240 can be disposed on the connecting seat 2210 and at least partially accommodated in the button slot 2213. Specifically, referring to the internal structure of the connecting seat 2210 after removal of the inner cover 2210b as shown in FIG. 28, in an embodiment, the release operating member 2240 can include a pivot shaft 2242 and operating portions 2241 and engaging portions 2244 disposed 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 user pressing operation. The size and shape of the operating portion 2241 can match the size and shape of the button slot 2213.In order to be installed in the button slot 2213. The operation portion 2241 and the engaging portion 2244 can be located on the front and back of the pivot shaft 2242, respectively. The engaging portion 2244 can be provided with a first engaging member 2244a and a second engaging member 2244b in the second direction. The first engaging member 2244a and the second engaging member 2244b can be formed as hook-shaped protrusions, which protrude towards the locking insert 2121 inserted in the insertion slot 2211 of the connecting seat 2210. The first engaging member 2244a and the second engaging member 2244b can each have an inclined surface 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 engaging hole 2126a and the second engaging hole 2126b of the locking insert 2121 in the locked state, and disengage from the engaging holes in the released state. Details will be described below. The inside of the connecting seat 2210 can also be formed with a right reinforcing rib 2216 and a guide rib 2217. The reinforcing rib 2216 can strengthen the structural strength of the connecting seat 2210, and the guide rib 2217 can limit and guide the release operation member 2240 and the locking insert 2121 in addition to strengthening the structural strength of the connecting seat 2210. The pivot shaft 2242 is located in the pivot slot 2212 defined by the guide rib 2217, and the pivot shaft 2242 can rotate in the pivot slot 2212. The axial direction of the pivot shaft 2242 can be arranged along the first direction, or can be arranged along other directions, which is not limited in the present disclosure. Therefore, by applying a pressing force to the operation portion 2241 towards the lateral inside, the engaging portion 2244 can be pivoted towards the outside around the pivot shaft 2242, so that the first engaging member 2244a and the second engaging member 2244b of the engaging portion 2244 can disengage from the first engaging hole 2126a and the second engaging 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 of the inside of the connecting seat 2210. Optionally, the connecting posts 2214 are 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 in a direction perpendicular to the inner surface of the outer cover 2210a. In an embodiment, the connecting posts 2214 are claw-shaped post structures. It can be understood that,The connecting post 2214 can also be formed as a solid cylinder. Referring to FIGS. 29-30, the structure and connection relationship of the docking seat 2120, the connecting seat 2210, and the release operation member 2240 according to an embodiment of the present disclosure are specifically shown, wherein the locking insert 2121 of the docking seat 2120 and the release operation member 2240 constitute a snap-on and disassembly structure. FIGS. 29 and 30 respectively show the corresponding changes of the snap-on and disassembly structure when the child seat 20 is in a locked state and a released state. In an embodiment, the release operation member 2240 can further include a second return member 2243. One end of the second return member 2243 is connected to the snap-on portion 2244, and the other end can be fixed to a position in the connecting seat 2210. The second return member 2243 exerts an elastic force on the snap-on portion 2244, so that the release operation member 2240 has a tendency to keep the snap-on portion 2244 in a locked position where the snap-on holes are engaged with each other. The first return member 2243 can be a coil spring, a leaf spring, or other elastic members. In FIG. 29, the child seat 20 is in a locked state. In an embodiment, the locking insert 2121 enters the connecting seat 2210 along the second direction (i.e., backward movement) through the insertion slot 2211, the first snap-on hole 2126a of the locking insert 2121 first engages with the second snap-on member 2244b of the snap-on portion 2244, the locking insert 2121 is further pushed inward, the first snap-on hole 2126a disengages from the second snap-on 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 backward along the first direction. At this point, the first snap-on hole 2126a engages with the first snap-on member 2244a, and the second snap-on hole 2126b engages with the second snap-on member 2244b, so that the locking insert 2121 cannot move forward along the second direction, thereby cannot be separated from the connecting seat 2210. That is, the locking insert 2121 cannot move along the first direction, thereby cannot be separated from the connecting seat 2210, by the engagement of the first and second snap-on holes 2126a and 2126b with the first and second snap-on members 2244a and 2244b of the snap-on portion 2244, and the abutment of the locking portion 2125 and the guide rib 2217. It can be understood that only one snap-on hole or more than two snap-on holes can be provided, and corresponding snap-on members can be provided. It can also be understood that the number of snap-on holes and snap-on members can be inconsistent. The insertion slot 2211 can also limit the downward movement of the locking insert 2121. In addition,The locking insert 2121 can be limited to slide along the insertion direction or move up and down by designing corresponding guide ribs 2217 in the connection seat 2210. When the child seat 20 is in the locked state, the release operation member 2240 is constantly subjected to an action force applied by the second return member 2243, and the first and second engaging members 2244a and 2244b can remain engaged with the first and second engaging holes 2126a and 2126b, so that the locking insert 2121 remains in the position engaged with the release operation member 2240. In FIG. 30, the child seat 20 is in the released state. In an embodiment, pressing the operation portion 2241 of the release operation member 2240, the operation portion 2241 moves toward the inside of the connection seat 2210 around the pivot shaft 2242, and drives the engaging portion 2244 to move toward the outside of the connection seat 2210 against the action force applied by the first return member 2243, until the first and second engaging members 2244a and 2244b disengage from the first and second engaging holes 2126a and 2126b. Thus, the locking insert 2121 disengages from the release operation member 2240. At this time, the locking insert 2121 can move outward (i.e., forward movement) away from the connection seat 2210 along the first direction through the insertion slot 2211. FIG. 31 is a side view schematic diagram of the base 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 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 welding, soldering, 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 connection column 2214, and a sleeve 2215. The inner cover 2210b can be provided with a plurality of sleeves 2215, which can correspond to the connection columns 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,

[0003] The sleeve 2215 can extend along a direction perpendicular to the surface of the inner cover 2210b to the side away from the inner 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, which is limited by the present disclosure. By the cooperation of the connecting column 2214 and the sleeve 2215, the welding energy consumption can be greatly reduced under the premise of 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. Figure 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 can 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 piece, which is not limited by the present disclosure. The support rod 2230 can be formed as a rod piece with a non-circular cross section, and the size and shape of the K-shaped 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 K-shaped hole 2223 when the support rod 2230 is installed to the rocker 2220. The cross-sectional profile of the support rod 2230 is not limited to this, and can also have an inverted triangular, rectangular, elliptical, hexagonal cross-sectional profile.The first reset member 2231 can be an elastic pin or an elastic body made of elastic material, without limitation. The first reset member 2231 can move between the convex and the retracted position of the circumferential wall of the support rod 2230. 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 outside the circumferential wall of the support rod 2230. When the two ends of the support rod 2230 are inserted into the clamping hole 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 this 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, and the details are not described herein. 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. In this way, 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 a high chair 2300 according to another embodiment of the present application is shown, to which a seat assembly 2100 according to one or more embodiments of the present application is installed. The user can disassemble the seat assembly 2100 and the chassis assembly 2200 of the child seat 20 according to one or more embodiments of the present application, 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 carriers or support assemblies, without limitation. 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 arranged at the joint of the first leg 2310 and the arm 2330. When the seat assembly 2100 is mounted to the high chair 2300, the insertion seat 2120 is connected to the connecting seat 2340 through a snap-on dismounting structure. Only the differences between the snap-on dismounting structure of the present embodiment and the above-mentioned embodiments will be described below, and the same or similar parts will be omitted. The locking insert 2121 can be inserted into the connecting seat 2340 along the second direction through the insertion slot 2341. When entering the insertion slot 2341, the supporting arm 2124 can be elastically deformed to be displaced 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 the predetermined position in the connecting seat 2340, the supporting 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 snapped with the limiting step 2342 on the first leg 2310. The sidewall 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, and the stop portion 2343 can limit the locking portion 2125 together with the sidewall 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 first 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 measuring the particular quantity based on 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 concepts 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 surface.The child swing 30 can include a seat assembly 3100 and a chassis assembly 3200 supporting the seat assembly 3100. The seat assembly 3100 is configured to support and mount a seat or a seat cloth for placing a child on the seat or the seat cloth for swinging 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 docking seat 3120. The seat frame 3110 is configured to support and mount the seat or the seat cloth. The seat frame 3110 can be located above the docking seat 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, or the like. The seat frame 3110 can be fixedly connected to the docking seat 3120 by welding or the like, or the two can be integrally formed, but the disclosure is not limited thereto. The docking seat 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 docking seat 3120 is optionally matched with the width of the lower surface of the seat frame 3110. The docking seat 3120 can be fixedly arranged at a position slightly below the middle of the seat frame 3110 along the longitudinal direction of the seat frame 3110 on both sides of the seat frame 3110, so as to facilitate the child swing 30 to be in a forward-leaning posture in a stationary state. For example, the midpoint of the connection position of the docking seat 3120 and the seat frame 3110 is located in 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, swing rods 3220, and support rods 3230. Two swing rods 3220 are arranged on the left and right sides of the child swing 30, respectively. Each swing rod 3220 can be an arc-shaped rod, thereby achieving forward and backward swinging after being placed on the ground. The connecting seat 3210 can be located above the swing rods 3220. The connecting seat 3210 can be fixedly connected to the swing rods 3220 by welding or the like, or can be integrally formed with the swing rods 3220, but the 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 swing rods 3220. The connecting seat 3210 can extend from the upper surface of the swing rods 3220 toward the seat assembly 3100, in other words, upward along the first direction. The connecting seat 3210 can be fixedly arranged at a position substantially in the middle of the longitudinal direction of the swing rods 3220. For example, the midpoint of the connection position of the connecting seat 3210 and the swing rods 3220 is located in the range of 1 / 3-1 / 2 of the length of the swing rods 3220.Optionally, the first direction forms an angle a with the vertical direction, the angle a being between 10° and 45° (see FIGS. 44A-44B), which facilitates the child rocker 30 to maintain a forward-leaning posture in a stationary state after being installed in place. A support rod 3230 can be disposed between the two rocker bars 3220 on both sides of the child rocker 30, and the two ends of the support rod 3230 are fixedly connected with the rocker bars 3220, respectively. The support rod 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 forms an angle B with the front-rear direction, and optionally, the angle B is between 10° and 45° (see FIGS. 39A-39B), so that the child can lie comfortably on the child rocker 30. Preferably, in an embodiment, after the seat assembly 3100 and the chassis assembly 3200 are installed in place, the insertion seat 3120 and the connecting seat 3210 extend upwardly obliquely, and the seat frame 3110 extends downwardly obliquely in the front-rear direction. It can also be said that the connection between the insertion seat 3120 and the seat assembly 3110 and the connection between the connecting seat 3210 and the rocker bar 3220 are staggered with each other in the front-rear direction. Such a configuration can make the seat assembly 3100 have a downwardly oblique orientation suitable for infant use on one side, and have good support on the other side. Preferably, in an embodiment, the front side of the connection between the insertion seat 3120 and the seat frame 3110 forms an acute angle, or in other words, the front side of the upper end of the insertion seat 3120 forms an acute angle 9 with the seat frame 3110 (as shown in FIGS. 44A-44B), since the connection between the insertion seat 3120 and the seat frame 3110 is close to the longitudinal front part of the seat frame 3110, such a configuration makes the seat assembly 3100 not cause excessive shear stress on the insertion 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 detachable structure between the insertion seat 3120 and the connecting seat 3210. Specifically, the seat assembly 3100 can be inserted into the chassis assembly 3200 along a second direction, as shown in FIGS. 39A-39C, and 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, and at this time, the acute angle between the first direction and the second direction is between 45° and 80°. Of course, the first direction can also form an angle with the front-rear direction, for example, the acute angle between the first direction and the first direction is between 0° and 30°, and the present disclosure is not limited thereto.The lower surface of the plug-in socket 3120 can optionally match the upper surface of the connecting seat 3210. When the plug-in socket 3120 is plugged into the connecting seat 3210, the circumferential wall of the plug-in socket 3120 is flush with the circumferential wall of the connecting seat 3210, making the product more aesthetically pleasing. When the child rocker 30 is in a stationary state, the front-to-back direction projection length of the seat frame 3110 on the horizontal plane can be slightly less than the rocker 322. The front-to-back direction projection length of the seat frame 3110 on the horizontal plane can be equal to, slightly less than, or slightly greater than the lateral projection length of the rocker 3220 on the horizontal plane (see FIGS. 34-35), which is conducive to the overall stability of the child rocker 30. FIG. 35 shows the child rocker 30 viewed from the back. In one embodiment, the connecting seat 3210 is provided with a release operation member 3240 on the back surface toward the longitudinal rear side. The release operation member 3240 can be arranged in the outwardly open button groove 3213 of the connecting seat 3240. The release operation member 3240 can be located at approximately the middle position of the back surface of the connecting seat 3210 in the vertical direction, so as to facilitate user operation. When the child rocker 30 is in a locked state, the outer surface of the release operation member 3240 is approximately flush with the outer surface of the connecting seat 3210 (see FIGS. 39A, 44A-44B, 45A-45C), making the overall appearance of the child rocker 30 more aesthetically pleasing, while also preventing improper operation caused by accidental contact by 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 rocker 30 in a disassembled state according to an embodiment of the present disclosure. The locking plug-in 121 is arranged on the plug-in socket 3120 and fixedly connected with the plug-in socket 3120. The locking plug-in 121 can be arranged on the surface where the plug-in socket 3120 and the connecting seat 3210 are joined. The locking plug-in 121 can extend from the plug-in socket 3120 in the second direction, optionally in the front-to-back direction, or at an angle to the front-to-back direction. The locking plug-in 121 can be provided with a locking protrusion 31211. In one embodiment, the locking plug-in 121 can include a locking protrusion 31211 extending from the body of the locking plug-in 121. The locking protrusion 31211 can form a limiting portion 31212 at the extension site where it is connected to the body, which can be clamped with the limiting step 3251 of the locking member 3250 (see FIG. 39A), which will be described in detail below.The position of the insertion slot 3211 corresponds to the position of the locking insert 121, and is optionally arranged on the surface of the connecting seat 3210 that engages with the insertion seat 3120. In an embodiment, the insertion slot 3211 can be open towards the front side of the child rocker 30, for the locking insert 121 to be inserted thereinto in a rearward direction. It can be understood that in another embodiment, the insertion slot 3211 can be open towards the rear side of the child rocker 30 or in other directions, for the locking insert 121 to be inserted thereinto in a forward direction or other directions. Optionally, the locking insert 121 can further comprise an arm 31213, and the locking protrusion 31211 is arranged at the end of the arm 31213, and the locking protrusion 31211 can form a limiting portion 31212 at the extension thereof that is connected with the arm 31213. The arm 31213 extends from the insertion seat 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 avoidance if 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 comprise an additional locking portion 31214, and the additional locking portion 31214 can be further provided with an engaging hole 31215 for engaging with the locking structure of other structures, so that the seat assembly 3100 is mounted and locked with other structures, thereby increasing the universality of the seat assembly 3100. Optionally, the insertion seat 3120 has an arc-shaped insertion surface 3122 that is concave, and the connecting seat 3210 has an arc-shaped mating surface 3218 that is convex and corresponds to the arc-shaped insertion surface 3122. When the insertion seat 3120 is inserted into the connecting seat 3210, the arc-shaped insertion surface 3122 cooperates with the arc-shaped mating surface 3218, so that the surface of the insertion seat 3120 and the connecting seat 3210 are flush. The locking insert 121 extends outwardly from the arc-shaped insertion surface 3122 in the second direction. Referring to FIGS. 38 and 39A-39C, the structure and connection relationship of the insertion seat 3120, the connecting seat 3210, the unlocking operation member 3240 and the locking member 3250 according to an embodiment of the present disclosure are specifically shown, wherein the locking insert 121 of the insertion seat 3120, the unlocking operation member 3240 and the locking member 3250 constitute an engaging and disassembling structure. FIGS. 39A, 39B and 39C respectively show the corresponding changes of the engaging and disassembling structure when the child rocker 30 is in a locked state, an unlocked state and a 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 formed in a rectangular or elliptical shape or other shape, and a corrugated or anti-skid coating can be provided thereon to facilitate user pressing operation. The operation portion 3241 and the driving protrusion 3244 can be respectively provided at two ends of the connecting rod 3242. The connecting rod 3242 can extend longitudinally from the bottom of the operation portion 3241, and can be formed in a rectangular rod. The driving protrusion 3244 can extend transversely from the end of the connecting rod 3242 away from the operation portion 3241, and can be formed in a cylindrical shape. The locking member 3250 can include a driving inclined slot 3252 cooperating 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 connecting rod 3242 can be driven to slide along a first direction, thereby driving the driving protrusion 3244 to slide relative to the driving inclined slot 3252, and further driving the locking member 3250 to move along a third direction between the locking position and the unlocking position. The third direction can be 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 is connected to the operation portion 3241, and the other end can be connected to a corresponding position in the connecting seat 3210. The restoring member 3243 applies an elastic force to the operation portion 3241, so that the unlocking operation member 3240 has a tendency to keep the locking member 3250 in the locking position. The restoring member 3243 can be a spiral spring, a leaf spring or other elastic member. In the present embodiment, the locking member 3250 moves in a linear manner along the third direction, and the third direction is transverse to the first direction. In other embodiments not shown, the locking member 3250 can switch between the locking position and the unlocking position in a non-linear manner along the third direction (e.g., clockwise or counterclockwise direction). In other embodiments not shown, the unlocking operation member 3240 can also not include the connecting 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 seat 3210 and the locking member 3250, and directly applies an elastic force to the locking member 3250, so that the locking member 3250 has a tendency to keep in the locking position.As shown in FIGS. 38 and 39A-39C, in an embodiment, the connection seat 3210 is formed with a button slot 3213, which is located opposite to the insertion slot 3211 in the longitudinal direction. In an embodiment, the button slot 3213 can be located on the back of the connection seat 3210. The button slot 3213 can be sized and shaped to match the size and shape of the operation part 3241. The interior of the connection seat 3210 is further formed with guide ribs 3217, which can not only strengthen the structural strength of the connection seat 3210, but also limit and guide the release operation piece 3240, the matching piece 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 connection seat 3210, the release operation piece 3240, the matching piece 3250 and the locking insert 121. The matching piece 3250 is slidably arranged on the release operation piece 3240, so that the release operation piece 3240 can drive the matching piece 3250 to slide in the connection seat 3210, so that the matching piece 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 piece 3250 can be slidably arranged in the interior of the connection seat 3210 through the guide ribs 3217 on the inner surface of the connection seat 3210, and the guide ribs 3217 can also limit the matching piece 3250. Specifically, the matching piece 3250 can slide along the fifth guide rib 32175, the seventh guide rib 32177 and the eighth guide rib 32178 in the third direction, while the third guide rib 32173 and the sixth guide rib 32176 limit or support the matching piece 3250 on the upper side and the lower side of the sliding direction thereof, respectively. In some embodiments, optionally, the matching piece 3250 further comprises a limiting slot 3253, which can also be an elongated slot. The limiting slot 3253 is arranged along the sliding direction of the matching piece 3250, i.e., extends along the third direction. The limiting slot 3253 forms an included angle Y with the extension direction of the driving inclined slot 3252, and optionally, the included angle Y is between 40°-70° (as shown in FIG. 41). Correspondingly, the interior of the connection seat 3210 can be further formed with a limiting protrusion 3212. The limiting protrusion 3212 can be formed as a boss matching the shape of the limiting slot 3253, and the length of the limiting protrusion 3212 is less than the length of the limiting slot 3253, so that the matching part 3250 can slide along the third direction relative to the limiting protrusion 3212.The limiting groove 3253 of the locking piece 3250 can be engaged with the limiting protrusion 3212, and the locking piece 3250 can slide along 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 effect on the locking piece 3250 can be realized. 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 provided, and the guiding rib 3217 for the locking piece 3250 is not provided; or only the corresponding guiding rib 3217 for the locking piece 3250 can be provided, and the limiting groove 3253 and the limiting protrusion 3212 are not provided; of course, both the limiting groove 3253 and the limiting protrusion 3212 and the guiding rib 3217 for the locking piece 3250 can be provided. 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 engaged 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 figure, the locking piece 3250 only includes the limiting groove 3253 and does not include the driving inclined groove 3252. At this time, the unlocking operation piece 3240 is directly formed on one side of the locking piece 3250, and the movement direction of the unlocking operation 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 unlocking operation piece 3240, and the unlocking operation piece 3240 directly drives the locking piece 3250 to switch between the locking position and the unlocking position along the third direction. In this case, the reset piece 3243 is directly arranged between the connecting seat 3240 and the unlocking operation piece 3240. In FIG. 39A, the child rocking chair 30 is in a 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 in 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 first guide rib 32172 in the connecting seat 3210 can also limit the locking insert 121 from continuing to slide in the insertion direction (i.e., along the first direction towards the rear) or moving up and down. Alternatively, the first 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 to facilitate abutting against and sliding 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 325 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 piece 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 state where the locking piece 3250 is in the locked state, 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 can be clamped with the limiting step 3251. 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 state where the locking piece 3250 is in the locked state, the upper surface of the locking piece 3250 is higher than the upper surface of the third guide rib 32173 in the height direction. Force is applied to the unlocking operation piece 3240 along the second direction, so that the connecting rod 3242 slides along the fourth guide rib 32174, and then the driving protrusion 3244 slides upward along the driving chute 3252, 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, a user can apply a force to the connector 3120 along the second direction, so that the locking connector 121 can be removed from the connecting seat 3210 along the second direction, so that the seat assembly 3100 and the frame assembly 3200 are separated, at this time, the child rocker 30 is in the disassembled state (as shown in FIG. 39C). Then the unlocking operation piece 3240 is released, and the unlocking operation 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 downward along the driving chute 3252, 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 second direction side of the locking piece 3250 can abut against the eighth guide rib 32178 in the connecting seat 3210, which can be connected with the ninth guide rib 32179 guiding the lower edge of the locking protrusion 31211 in the connecting seat 3210, wherein at least a part of the ninth guide rib 32179 is arc-shaped, which is beneficial for the locking protrusion 31211 to move away from the connecting seat in the unlocking state.

During the switching of the standing leg 3260 between the unfolded position, the transition position and the collapsed position, the pivot shaft 3270 moves around the arc-shaped edge of the cam slot 3262. In the present embodiment, the standing leg 3260 is provided in two, respectively arranged on the corresponding rocker 3220. In other embodiments, the standing leg 3260 can be provided with only one, which is not limited by the present disclosure. Continue to refer to FIGS. 45A-45C, the end surface of the supporting end 3263 of the standing leg 3260 is inclined, that is, when the standing leg 3260 is collapsed in the receiving slot 3281 of the fixed base 3280, the end surface of the supporting end 3263 is inclined relative to the circumferential wall surface of the receiving slot 3281, and when the standing leg 3260 is in the unfolded state, the end surface of the supporting end 3263 can be parallel to the supporting surface of the child rocker 30, so that the standing leg 3260 can stand more stably on the supporting surface, thereby providing more stable support to the child rocker 30.The end surface of the abutting end 3264 of the standing leg 3260 is a flat surface, that is, when the standing leg 3260 is folded into the receiving groove 3281 of the fixing seat 3280, the end surface of the abutting end 3264 of the standing leg 3260 is parallel to the circumferential wall surface of the receiving groove 3281, which is conducive to better fitting the standing leg 3260 with the circumferential wall surface of the receiving groove 3281. In addition, the length of the bottom surface of the standing leg 3260 provided with the handle groove 3261 is equal to or slightly greater than the length of the receiving groove 3281, so that the standing leg 3260 in the folded state can be tightly abutted against the circumferential side wall of the receiving groove 3281. Optionally, one side of the abutting end 3264 of the standing leg 3260 is provided with a right transition portion 3265, which is in the shape of a rounded shape. Since the end surface of the abutting end 3264 is a flat surface, the provision of the transition portion 3265 can make the switching of the standing leg 3260 between the folded position and the unfolded position around the pivot shaft more smooth. In an embodiment, a non-slip strip 3290 (as shown in FIG. 47) can be provided on the bottom surface of the rocker 3220 of the child rocker 30, thereby increasing the friction between the child rocker 30 and the supporting surface (ground). Alternatively or additionally, an elastic rubber paint can be applied on the bottom surface of the rocker 3220 of the child rocker 30, or an elastic rubber pad can be attached, or other similar ways can be used to increase the friction between the child rocker 30 and the ground. Taking the elastic rubber paint as an example, it can contain ingredients similar to rubber properties, such as elastic paint, touch paint, leather paint, rubber paint, velvet paint, rubber oil, etc. The thickness of the elastic rubber paint is about 0.3mm, which will not affect the product appearance of the child rocker 30, and the process of applying the elastic rubber paint is simple, which can save manufacturing costs. Before applying the elastic rubber paint on the bottom surface of the rocker 3220 of the child rocker 30, the rocker 3220 can only be simply cleaned, without the need to apply ordinary paint on the bottom surface of the rocker 3220, which can further reduce the processing steps and save manufacturing costs. Optionally, when the rocker 3220 of the child rocker 30 is provided with the standing leg 3260, the surface of the standing leg 3260 and the supporting end 3263 can also be provided with similar non-slip strips and / or elastic rubber paint to increase the friction between the standing leg 3260 and the supporting surface, which will not be described here.
