However, in the related art swing chair, due to the unreasonable design of the folding seat, the swing chair is prone to deformation or even fracture during the process of switching from the supporting state to the folded state or from the folded state to the supporting state, posing a safety hazard. Utility Model Content

[0004] The embodiments of this application provide a swing frame and a swing chair, which can solve the problem that the folding seat of the swing chair in the related art is deformed or even fractured due to unreasonable structural design, resulting in low safety of the swing chair.

[0005] In a first aspect, the embodiments of this application provide a swing frame; the swing frame includes a support seat, a folding seat, and support feet. The support seat has a receiving area. The folding seat includes a seat body, at least part of the seat body is located in the receiving area and is rotatably connected to the support seat. The seat body has an installation area, and a reinforcing body is arranged in the installation area. The end of the support foot is located in the installation area and is connected to the seat body.

[0006] Based on the swing frame of the embodiments of this application, by designing the reinforcing body, the reinforcing body can strengthen the structural strength of the seat body to enhance the overall structural strength of the folding seat. In this way, the possibility of the folding seat being deformed or fractured under the extrusion of the support feet can be effectively reduced, thereby effectively reducing or even eliminating the safety hazard of the swing frame.

[0007] In some of these embodiments, the seat body includes two shells and fasteners; the two shells jointly enclose to form the installation area, and the two shells have correspondingly arranged fixing positions; the reinforcing body is arranged adjacent to the fixing positions and is connected to at least one shell; the fasteners fix and connect the two shells corresponding to the fixing positions; at least one shell is rotatably connected to the support seat, and at least one shell is connected to the end of the support foot.

[0008] Based on the above embodiment, two shells are designed to enclose a mounting area to wrap the ends of the supporting legs.

[0009] In some of the embodiments, two shells are enclosed to form an opening for the supporting leg to pass through the installation area; the fixing position includes a first fixing hole farthest from the opening, and the first fixing hole is arranged closer to the lower edge of the shell than to the upper edge of the shell; the reinforcement body includes a first reinforcement rib, the first reinforcement rib is located between the lower edge of the shell and the hole edge of the first fixing hole, and one end of the first reinforcement rib is connected to the lower edge of the shell.

[0010] Based on the above embodiment, the first fixing hole is used as one of the fixing positions to cooperate with the above fastener to achieve relative fixation of the position between the two shells. By designing a first reinforcing rib between the lower edge of the shell and the edge of the first fixing hole, the first reinforcing rib can enhance the structural strength of the lower edge of the shell on the one hand, and enhance the structural strength of the shell near the first fixing hole on the other hand, so as to effectively reduce the possibility of deformation or breakage of the shell near the first fixing hole due to excessive force during the connection between the fastener and the first fixing hole.

[0012] Based on the above embodiment, by designing a second reinforcing rib along the edge of the first fixing hole, the second reinforcing rib can enhance the structural strength of the shell at the edge of the first fixing hole, which can further effectively reduce the possibility of deformation or breakage of the shell near the first fixing hole due to excessive force during the connection process between the fastener and the first fixing hole. By designing the other end of the first reinforcing rib to overlap with the second reinforcing rib, so that the other end of the first reinforcing rib relies on the second reinforcing rib, the structural strength of the first reinforcing rib itself can be improved, thereby further enhancing the structural strength of the lower edge of the shell.

[0013] In some of the embodiments, the two shells are enclosed to form an opening for the supporting leg to pass through the installation area; the fixing position also includes a second fixing hole closest to the opening, and the second fixing hole is arranged farther away from the lower edge of the shell than the upper edge of the shell; the reinforcement body also includes a third reinforcement rib, which is radially arranged on both sides of the second fixing hole and connected to the inner wall of the shell, and / or the reinforcement body also includes a fourth reinforcement rib, which is arranged along the edge of the second fixing hole and connected to the inner wall of the shell.

In this way, the possibility that the housing near the second fixing hole is deformed or broken due to excessive force during the connection between the fastener and the second fixing hole can be effectively reduced. And / or, by designing the fourth reinforcing rib along the hole edge of the second fixing hole, the fourth reinforcing rib can enhance the structural strength of the housing at the hole edge of the second fixing hole, so as to further effectively reduce the possibility that the housing near the second fixing hole is deformed or broken due to excessive force during the connection between the fastener and the second fixing hole.

[0016] Based on the above embodiments, by designing the fifth reinforcing rib along the hole edge of the rotating hole, the fifth reinforcing rib can enhance the structural strength of the housing at the hole edge of the rotating hole, so as to effectively reduce the possibility that the housing near the rotating hole is deformed or broken due to excessive force during the relative rotation between the housing and the support base. And / or, by designing the sixth reinforcing rib, the sixth reinforcing rib can enhance the structural strength of the housing near the rotating hole, so as to effectively reduce the possibility that the housing near the rotating hole is deformed or broken due to excessive force during the relative rotation between the housing and the support base.

[0017] In some of the embodiments, the swing frame further includes a speed control knob, a blocking member, and a limiting member; the speed control knob is rotatably connected to the support base and is used to adjust the swing frequency of the child seat; the blocking member is connected to the speed control knob; the limiting member is connected to the support base; when the speed control knob is rotated to adjust the swing frequency of the child seat to the maximum, the limiting member abuts against the blocking member.

[0019] In some of these embodiments, the blocking member includes a blocking rib connected to the speed control knob; the limiting member includes an arc-shaped limiting rib fixedly connected to the support base, and the center of the arc of the arc-shaped limiting rib lies on the rotation axis of the speed control knob; when the speed control knob rotates to adjust the swing frequency of the child seat to the maximum, one end of the blocking rib abuts against the arc-shaped limiting rib.

Detailed implementation manners

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] Please refer to Figures 1 - 5 As shown, in a first aspect, the present application provides a swing frame 10, which can effectively reduce or even eliminate the safety hazards of the swing frame 10.

[0039] The swing frame 10 includes a support base 11, a folding base 12, and support feet 13. The support base 11 has a receiving area 11a. The folding base 12 includes a base body 121; at least part of the base body 121 is located in the receiving area 11a and is rotatably connected to the support base 11. The base body 121 has a mounting area 121a; a reinforcing body 122 is provided in the mounting area 121a. The end of the support foot 13 is located in the mounting area 121a and is connected to the base body 121.

[0040] The following combines Figures 1 - 10 to introduce the specific structure of the swing frame 10 in detail. The swing frame 10 includes a support base 11, a folding base 12, and support feet 13.

[0041] As Figures 1 - 5 shown, the support base 11 serves as the support of the swing frame 10 to carry structural members such as the folding base 12; the specific structure of the support base 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the support base 11 can be in the form of a plate structure or a hollow shell 1211 structure.

[0042] The support base 11 has a receiving area 11a; the receiving area 11a is the area of the support base 11 for accommodating / placing structural members such as the folding base 12. It can be understood that for different structures of the support base 11, the specific manifestation form of the receiving area 11a is also different; for example, when the support base 11 is in the form of a plate structure, the receiving area 11a can be the area corresponding to one / more surfaces of the plate; and for another example, when the support base 11 is in the form of a hollow shell 1211 structure, the receiving area 11a can be the internal hollow area of the hollow shell 1211.

[0043] As Figures 1 - 5 shown, the folding base 12 serves as a connecting member of the swing frame 10 to realize the connection between the support legs 13 and the support base 11. The folding base 12 includes a base body 121.

[0044] The base body 121 serves as the connecting main body of the folding base 12; the specific structure of the base body 121 is not limited here, and designers can make reasonable designs according to actual needs; for example, the base body 121 can be in the form of a plate structure or a hollow shell 1211 structure.

[0045] At least a part of the seat body 121 is located in the accommodation area 11a of the support seat 11. For example, when the seat body 121 is in the form of a plate structure and the support seat 11 is also in the form of a plate structure, at least a part of the projection of the area corresponding to the outer contour line of the seat body 121 falls on the surface of the support seat 11 that serves as the accommodation area 11a. Another example is that when the seat body 121 is in the form of a hollow shell 1211 structure and the support seat 11 is in the form of a plate structure, at least a part of the projection of the area corresponding to the outer contour line of the seat body 121 falls on the surface of the support seat 11 that serves as the accommodation area 11a. Still another example is that when the seat body 121 is in the form of a plate structure and the support seat 11 is in the form of a hollow shell 1211 structure, at least a part of the seat body 121 is accommodated in the internal hollow area of the support seat 11. Yet another example is that when the seat body 121 is in the form of a hollow shell 1211 structure and the support seat 11 is also in the form of a hollow shell 1211 structure, at least a part of the seat body 121 is accommodated in the internal hollow area of the support seat 11, and the seat body 121 and the support seat 11 form a double-shell 1211 structure of inner and outer nesting.

[0046] The seat body 121 is rotatably connected to the support seat 11; the specific rotational connection manner between the seat body 121 and the support seat 11 is not limited here, and designers can make a reasonable design according to actual needs; for example, the seat body 121 can be rotatably connected to the support seat 11 through a rotating shaft.

[0047] The seat body 121 has an installation area 121a; the installation area 121a is the area of the seat body 121 for installing the support leg 13. It can be understood that for seat bodies 121 of different structures, the specific manifestation forms of the installation area 121a are also different; for example, when the seat body 121 is in the form of a plate structure, the installation area 121a can be the area corresponding to one or more surfaces of the plate; another example is that when the seat body 121 is in the form of a hollow shell 1211 structure, the installation area 121a can be the internal hollow area of the hollow shell 1211.

[0048] As Figures 1 - 5 shown, the support foot 13 serves as a leg of the swing frame 10 to provide support for the children's seat 20 (introduced below) of the swing chair 1; the specific structure of the support foot 13 is not limited here, and designers can make a reasonable design according to actual needs; for example, the support foot 13 can be, but is not limited to, in the form of a rod structure.

[0049] It should be noted that the number of the supporting feet 13 can be one. For example, taking the swing frame 10 including a U-shaped supporting foot as an example, in this case, the swing frame 10 can also include another U-shaped supporting foot, and this other supporting foot can be directly fixedly connected to the supporting seat 11. At this time, the supporting foot 13 rotates through the folding seat 12 to be close to the other supporting foot so that the swing frame 10 is in a folded state, or the supporting foot 13 rotates through the folding seat 12 to be away from the other supporting foot so that the swing frame 10 is in a supporting state. Of course, the number of the supporting feet 13 can also be multiple (more than two). For example, taking the swing frame 10 including two U-shaped supporting feet as an example, at this time, both of the two supporting feet 13 are rotatably connected to the supporting seat 11 through the folding seat 12, and the two supporting feet 13 rotate through the folding seat 12 to be close to each other so that the swing frame 10 is in the above-mentioned folded state, or the two supporting feet 13 rotate through the folding seat 12 to be away from each other so that the swing frame 10 is in the above-mentioned supporting state.

[0050] The end of the supporting foot 13 is located in the installation area 121a and is connected to the seat body 121. Here, the specific connection manner between the end of the supporting foot 13 and the seat body 121 is not limited, and the designer can make a reasonable design according to actual needs. For example, the end of the supporting foot 13 can be fixedly connected to the seat body 121 by at least one of the ways such as screwing, clamping or plugging, etc. Also for example, the end of the supporting foot 13 can also be rotatably connected to the seat body 121 by a rotating shaft. Again for example, the end of the supporting foot 13 can also be slidably connected to the seat body 121 by the cooperation of a slider and a sliding groove. It should be noted that if the supporting foot 13 is rotatably connected to the seat body 121, when the swing frame 10 is in a supporting state, at this time, the supporting foot 13 rotates relative to the seat body 121 to a preset supporting angle, and the supporting foot 13 and the seat body 121 remain relatively stationary (that is, the supporting foot 13 can no longer rotate relative to the seat body 121). If the supporting foot 13 is slidably connected to the seat body 121, when the swing frame 10 is in a supporting state, at this time, the supporting foot 13 slides relative to the seat body 121 to a preset supporting position, and the supporting foot 13 and the seat body 121 remain relatively stationary (that is, the supporting foot 13 can no longer slide relative to the seat body 121).

[0051] Considering that during the process of the swing frame 10 switching from the folded state to the supporting state or from the supporting state to the folded state under the action of an external force, the supporting foot 13 presses the seat body 121 and rotates relative to the supporting seat 11 together with the seat body 121, and the seat body 121 is likely to be deformed or broken under the action of this extrusion force. To enhance the overall structural strength of the folding seat 12 to effectively reduce the possibility of the seat body 121 being deformed or broken; as Figure 5 shown, the folding seat 12 further includes a reinforcing body 122.

[0052] The reinforcing member 122 is used as a reinforcing component of the folding seat 12 to enhance the overall structural strength of the folding seat 12; the specific form of the reinforcing member 122 is not limited here, and designers can make reasonable designs according to actual needs; for example, the reinforcing member 122 may but is not limited to including reinforcing rollers.

[0053] At least part of the reinforcing member 122 is located in the installation area 121a. For example, when the seat body 121 is in a plate structure, at least part of the projection of the area corresponding to the outer contour line of the reinforcing member 122 falls on the surface of the seat body 121 that serves as the installation area 121a. Another example is that when the seat body 121 is in a hollow shell 1211 structure, at least part of the reinforcing member 122 is accommodated in the internal hollow area of the seat body 121.

[0054] The reinforcing member 122 is connected to the seat body 121; the specific connection method between the reinforcing member 122 and the seat body 121 is not limited here, and designers can make reasonable designs according to actual needs; for example, the reinforcing member 122 may but is not limited to be detachably connected to the seat body 121 by at least one of the ways such as screwing, clamping or plugging; another example is that the reinforcing member 122 may also but is not limited to be non-detachably connected to the seat body 121 by means of gluing, injection molding or 3D printing. And it can be understood that for different specific forms of the reinforcing member 122, the specific connection methods between the reinforcing member 122 and the seat body 121 are also different; for example, when the reinforcing member 122 includes a reinforcing roller, the reinforcing roller may but is not limited to be fixedly connected to the seat body 121 by screwing / clamping / plugging.

[0055] Of course, the swing frame 10 may also include a folding button (not shown in the figure), and the folding button can be installed on the support seat 11. The folding button has a locked state and an unlocked state; in the locked state, the folding button is configured to lock the folding seat 12 to the support seat 11, and at this time the folding seat 12 remains stationary relative to the support seat 11; in the unlocked state, the folding button is configured to unlock the folding seat 12 from the support seat 11, and at this time the folding seat 12 can rotate relative to the support seat 11. The folding button is configured to be able to switch between the above-mentioned locked state and unlocked state under the action of an external force, so that the swing frame 10 can switch between the above-mentioned support state and the above-mentioned folding state. The specific structure of the folding button is not limited here, and designers can directly use a structure with a locking function (such as a wedge block) in related technologies according to actual needs. Since the folding button is not the main innovation point of this application, it will not be elaborated here.

[0056] Based on the swing frame 10 in the embodiments of the present application, by designing the reinforcing body 122, the reinforcing body 122 can strengthen the structural strength of the seat body 121 to improve the overall structural strength of the folding seat 12. In this way, the possibility of deformation or fracture of the folding seat 12 under the extrusion of the support feet 13 can be effectively reduced, thereby effectively reducing or even eliminating the safety hazards of the swing frame 10.

[0057] As Figure 3 and Figure 5 shown, when the seat body 121 has a hollow shell 1211 structure, the seat body 121 includes two shells 1211 and fasteners 1212. The two shells 1211 jointly enclose an installation area 121a, and the two shells 1211 have corresponding fixed positions; the fasteners 1212 fix and connect the two shells 1211 corresponding to the fixed positions. The reinforcing body 122 is arranged adjacent to the fixed position and connected to at least one shell 1211; at least one shell 1211 is rotatably connected to the support seat 11, and at least one shell 1211 is connected to the end of the support foot 13.

[0058] Among them, the fixed position is the part on the two shells 1211 used to cooperate with the fasteners 1212 to realize the relative fixation of the positions between the two shells 1211; the fasteners 1212 are the components used to cooperate with the fixed positions to realize the relative fixation of the positions between the two shells 1211. For different specific forms of the fixed positions, the specific forms of the fasteners 1212 cooperating with them are also different; for example, when the fixed position is a threaded hole on the two shells 1211, the fasteners 1212 include screws, and at this time, the two shells 1211 realize the relative fixation of their positions by means of the screws; another example is that when the fixed position is a card hole on the two shells 1211, the fasteners 1212 include a cotter pin, and at this time, the two shells 1211 realize the relative fixation of their positions by means of the cotter pin being snapped; still another example is that when the fixed position is a socket on the two shells 1211, the fasteners 1212 include a plug pin, and at this time, the two shells 1211 realize the relative fixation of their positions by means of the plug pin being inserted.

[0059] By designing the two shells 1211, the two shells 1211 enclose an installation area 121a to wrap the end of the support foot 13. By designing the fasteners 1212, the fasteners 1212 are used to cooperate with the fixed positions to realize the relative fixation of the positions between the two shells 1211, with a simple structure and being easy to implement.

[0060] As Figure 6As shown, the two shells 1211 are enclosed to form an opening 1211a for the support leg 13 to pass through the installation area 121a; the fixing position includes a first fixing hole 1211b farthest from the opening 1211a; the first fixing hole 1211b is arranged closer to the lower edge of the shell 1211 than the upper edge of the shell 1211. The reinforcement body 122 includes a first reinforcement rib 1221; the first reinforcement rib 1221 is located between the lower edge of the shell 1211 and the edge of the first fixing hole 1211b, and one end of the first reinforcement rib 1221 is connected to the lower edge of the shell 1211.

[0061] The first fixing hole 1211b may be a threaded hole, a clamping hole or a plug hole. The first reinforcing rib 1221 may be formed into an integrated structure with the housing 1211 by, but not limited to, injection molding or 3D printing.

[0062] The first fixing hole 1211b is used as one of the fixing positions to cooperate with the above-mentioned fastener 1212 to achieve relative fixation of the positions between the two shells 1211. By designing the first reinforcing rib 1221 between the lower edge of the shell 1211 and the edge of the first fixing hole 1211b, the first reinforcing rib 1221 can enhance the structural strength of the lower edge of the shell 1211 on the one hand, and enhance the structural strength of the shell 1211 near the first fixing hole 1211b on the other hand, so as to effectively reduce the possibility of deformation or breakage of the shell 1211 near the first fixing hole 1211b due to excessive force during the connection process between the fastener 1212 and the first fixing hole 1211b.

[0063] like Figure 6 As shown, the reinforcement body 122 also includes a second reinforcement rib 1222; the second reinforcement rib 1222 is arranged along the edge of the first fixing hole 1211b and connected to the inner wall of the shell 1211; the other end of the first reinforcement rib 1221 extends to overlap with the side of the inner wall of the shell 1211 away from the second reinforcement rib 1222.

[0064] The second reinforcing rib 1222 may be, but is not limited to, a block structure or an annular structure; for example, when the second reinforcing rib 1222 is a block structure, the number of the second reinforcing rib 1222 is multiple, and the multiple second reinforcing ribs 1222 are arranged at intervals along the edge of the first fixing hole 1211b; for another example, when the second reinforcing rib 1222 is an annular structure, if the number of the second reinforcing rib 1222 is one, then the one second reinforcing rib 1222 is arranged along the edge of the first fixing hole 1211b in one circle, and if the number of the second reinforcing rib 1222 is multiple, the multiple second reinforcing ribs 1222 are arranged along the edge of the first fixing hole 1211b in multiple circles. The second reinforcing rib 1222 may be, but is not limited to, formed into an integrated structure with the housing 1211 by injection molding or 3D printing; the first reinforcing rib 1221 and the second reinforcing rib 1222 may also be, but is not limited to, formed into an integrated structure by injection molding or 3D printing.

[0065] By designing the second reinforcing rib 1222 along the edge of the first fixing hole 1211b, the second reinforcing rib 1222 can enhance the structural strength of the shell 1211 at the edge of the first fixing hole 1211b, which can further effectively reduce the possibility of deformation or breakage of the shell 1211 near the first fixing hole 1211b due to excessive force during the connection process between the fastener 1212 and the first fixing hole 1211b. By designing the other end of the first reinforcing rib 1221 to overlap with the second reinforcing rib 1222, so that the other end of the first reinforcing rib 1221 relies on the second reinforcing rib 1222, the structural strength of the first reinforcing rib 1221 itself can be improved, thereby further enhancing the structural strength of the lower edge of the shell 1211.

[0066] like Figure 6 As shown, the fixing position also includes a second fixing hole 1211c closest to the opening 1211a; the second fixing hole 1211c is arranged farther away from the lower edge of the housing 1211 than the upper edge of the housing 1211. The second fixing hole 1211c can be a threaded hole, a card hole or a socket.

[0067] The second fixing hole 1211c is used as another fixing position to cooperate with the fastener 1212 to achieve relative fixation between the two shells 1211. The design of the reinforcement body 122 in the area of the shell 1211 corresponding to the second fixing hole 1211c can include but is not limited to one or more of the following embodiments.

[0068] In the first embodiment, the reinforcing body 122 further includes third reinforcing ribs 1223 ; the third reinforcing ribs 1223 are arranged on both sides of the second fixing hole 1211 c along the radial direction of the second fixing hole 1211 c and connected to the inner wall of the shell 1211 .

[0069] Among them, the third reinforcing rib 1223 can be, but is not limited to, a strip-shaped structure; the third reinforcing rib 1223 can be, but is not limited to, integrally formed with the housing 1211 by injection molding or 3D printing. The number of the third reinforcing ribs 1223 can be one or more.

[0070] By designing the third reinforcing rib 1223, on the one hand, the third reinforcing rib 1223 can enhance the structural strength of the upper edge of the housing 1211, and on the other hand, it can also enhance the structural strength of the housing 1211 near the second fixing hole 1211c. In this way, the possibility that the housing 1211 near the second fixing hole 1211c is deformed or broken due to excessive force during the connection between the fastener 1212 and the second fixing hole 1211c can be effectively reduced.

[0071] In the second embodiment, the reinforcing body 122 further includes a fourth reinforcing rib 1224; the fourth reinforcing rib 1224 is arranged along the hole edge of the second fixing hole 1211c and is connected to the inner wall of the housing 1211.

[0072] Among them, the fourth reinforcing rib 1224 can be, but is not limited to, an arc-shaped structure or a ring-shaped structure; for example, when the fourth reinforcing rib 1224 is an arc-shaped structure, the number of the fourth reinforcing ribs 1224 is multiple, and the multiple fourth reinforcing ribs 1224 are arranged at intervals along the hole edge of the second fixing hole 1211c; and for another example, when the fourth reinforcing rib 1224 is a ring-shaped structure, the fourth reinforcing rib 1224 is arranged along the hole edge of the second fixing hole 1211c. The fourth reinforcing rib 1224 can be, but is not limited to, integrally formed with the housing 1211 by injection molding or 3D printing; the third reinforcing rib 1223 can be, but is not limited to, integrally formed with the fourth reinforcing rib 1224 by injection molding or 3D printing.

[0073] By designing the fourth reinforcing rib 1224 along the hole edge of the second fixing hole 1211c, the fourth reinforcing rib 1224 can enhance the structural strength of the housing 1211 at the hole edge of the second fixing hole 1211c. In this way, the possibility that the housing 1211 near the second fixing hole 1211c is deformed or broken due to excessive force during the connection between the fastener 1212 and the second fixing hole 1211c can be further effectively reduced.

[0074] As Figure 6 shown, the housing 1211 is rotatably connected to the support base 11; the housing 1211 has a rotation hole 1211d for rotatably connecting to the support base 11; the housing 1211 includes a connecting shaft 111 (as Figure 9As shown; the connecting shaft 111 passes through the rotating hole 1211d. The rotating hole 1211d serves as the connecting hole of the housing 1211 and is used to realize the rotational connection between the housing 1211 and the support base 11; the design of the reinforcing body 122 in the area of the housing 1211 corresponding to the rotating hole 1211d can include, but is not limited to, one or more of the following embodiments.

[0075] In the first embodiment, the reinforcing body 122 further includes a fifth reinforcing rib 1225; the fifth reinforcing rib 1225 is arranged along the hole edge of the rotating hole 1211d and is connected to the inner wall of the housing 1211.

[0076] Among them, the fifth reinforcing rib 1225 can be, but is not limited to, a ring structure; the fifth reinforcing rib 1225 can be, but is not limited to, integrally formed with the housing 1211 by injection molding or 3D printing. The number of the fifth reinforcing ribs 1225 can be one or more.

[0077] By designing the fifth reinforcing rib 1225 along the hole edge of the rotating hole 1211d, the fifth reinforcing rib 1225 can enhance the structural strength of the housing 1211 at the hole edge of the rotating hole 1211d, so as to effectively reduce the possibility that the housing 1211 near the rotating hole 1211d is deformed or broken due to excessive force during the relative rotation of the housing 1211 and the support base 11.

[0078] In the second embodiment, the reinforcing body 122 further includes a sixth reinforcing rib 1226; the sixth reinforcing rib 1226 is radially arranged on both sides of the rotating hole 1211d and is connected to the inner wall of the housing 1211.

[0079] Among them, the sixth reinforcing rib 1226 can be, but is not limited to, a long strip structure; the sixth reinforcing rib 1226 can be, but is not limited to, integrally formed with the housing 1211 by injection molding or 3D printing. The number of the sixth reinforcing ribs 1226 can be one or more.

[0080] By designing the sixth reinforcing rib 1226, the sixth reinforcing rib 1226 can enhance the structural strength of the housing 1211 near the rotating hole 1211d, so as to effectively reduce the possibility that the housing 1211 near the rotating hole 1211d is deformed or broken due to excessive force during the relative rotation of the housing 1211 and the support base 11.

[0081] Of course, as Figure 6As shown, the fixed positions further include a third fixing hole 1211e located between the first fixing hole 1211b and the second fixing hole 1211c; the reinforcing body 122 further includes a seventh reinforcing rib 1227; the seventh reinforcing rib 1227 is arranged along the hole edge of the third fixing hole 1211e and is connected to the inner wall of the housing 1211; and / or, the reinforcing body 122 further includes an eighth reinforcing rib 1228, and the eighth reinforcing rib 1228 is arranged adjacent to the hole edge of the third fixing hole 1211e and is connected to the inner wall of the housing 1211.

[0082] It should be noted that the first fixing hole 1211b, the second fixing hole 1211c, and the third fixing hole 1211e cooperate with the corresponding fasteners 1212 to fix the two housings 1211 at least in three regions such as the front side, the middle side, and the rear side with reference to the opening 1211a, so as to effectively enhance the connection stability between the two housings 1211. And the mutual cooperation among the above-mentioned first reinforcing rib 1221 and second reinforcing rib 1222 designed for the region where the first fixing hole 1211b is located, the third reinforcing rib 1223 and fourth reinforcing rib 1224 designed for the region where the second fixing hole 1211c is located, the fifth reinforcing rib 1225 and sixth reinforcing rib 1226 designed for the region where the rotating hole 1211d is located, and the seventh reinforcing rib 1227 and eighth reinforcing rib 1228 designed for the region where the third fixing hole 1211e is located effectively strengthen the structural strength of the housing 1211 in different regions, thereby effectively improving the overall structural strength of the housing 1211.

[0083] As Figures 7 - 10 As shown, the swing frame 10 further includes a speed control knob 14, a blocking member 15, and a limiting member 16; the speed control knob 14 is rotatably connected to the support base 11 and is used to adjust the swing frequency of the child seat 20 of the swing chair 1; the blocking member 15 is connected to the speed control knob 14; the limiting member 16 is connected to the support base 11; when the speed control knob 14 rotates to adjust the swing frequency of the child seat 20 of the swing chair 1 to the maximum, the limiting member 16 abuts against the blocking member 15.

[0084] By designing the speed control knob 14, the caregiver can rotate the speed control knob 14 according to actual needs to adjust the swing frequency of the child seat 20 of the swing chair 1. By designing the blocking member 15 on the speed control knob 14 and the limiting member 16 on the support base 11, when the speed control knob 14 rotates to adjust the swing frequency of the child seat 20 of the swing chair 1 to the maximum, the limiting member 16 abuts against the blocking member 15, and the limiting member 16 plays a limiting role on the blocking member 15 to effectively reduce the possibility of damage to the speed control knob 14 connected to the blocking member 15 due to excessive rotation.

[0085] Specifically, as Figures 7 - 10As shown, the blocking member 15 includes a blocking rib 151 connected to the speed control knob 14; the limiting member 16 includes an arc-shaped limiting rib 161 fixedly connected to the support base 11; the circle of the arc-shaped limiting rib 161 lies on the axis of the rotating shaft of the speed control knob 14; when the speed control knob 14 rotates to adjust the swing frequency of the child seat 20 of the swing chair 1 to the maximum, the blocking rib 151 abuts against one end of the arc-shaped limiting rib 161. Among them, the blocking rib 151 can, but is not limited to, be integrally formed with the speed control knob 14 by injection molding or 3D printing; the arc-shaped limiting rib 161 can, but is not limited to, be integrally formed with the support base 11 by injection molding or 3D printing. By designing the blocking member 15 as the blocking rib 151 and the limiting member 16 as the arc-shaped limiting rib 161; when the speed control knob 14 rotates to adjust the swing frequency of the child seat 20 of the swing chair 1 to the maximum, the arc-shaped limiting rib 161 abuts against one end of the blocking rib 151, and the arc-shaped limiting rib 161 plays a role in limiting the blocking rib 151, so as to effectively reduce the possibility that the speed control knob 14 connected to the blocking rib 151 is damaged due to excessive rotation.

[0086] More specifically, as Figures 7 - 10 shown, other structural designs of the blocking rib 151 and the arc-shaped limiting rib 161 can, but are not limited to, include one or more of the following embodiments.

[0087] In the first embodiment, the blocking rib 151 is provided with a hollow hole 151a. Among them, the number of the hollow holes 151a can be one or more; the shape of the cross-section of the hollow hole 151a can, but is not limited to, be circular or rectangular. This can play a role in saving materials.

[0088] In the second embodiment, the arc-shaped limiting rib 161 has an arc-shaped cross-section perpendicular to the rotation axis of the speed control knob 14; the central angle corresponding to the inner arc line of the arc-shaped cross-section is greater than or equal to 80 degrees and less than or equal to 100 degrees. For example, the central angle corresponding to the inner arc line of the arc-shaped cross-section can, but is not limited to, be 80 degrees, 85 degrees, 90 degrees, 95 degrees or 100 degrees, etc. By designing the size of the central angle corresponding to the inner arc line of the arc-shaped cross-section, the possibility that the speed control knob 14 connected to the blocking rib 151 is damaged due to excessive rotation can be effectively reduced.

[0089] Of course, the limiting member 16 may also include two stop flanges (not shown in the figure). The two stop flanges are fixedly connected to the support base 11 and are arranged at intervals around the rotation axis of the speed control knob 14. The blocking member 15 correspondingly includes an abutting flange (not shown in the figure), and the abutting flange is fixedly connected to the speed control knob 14. When the speed control knob 14 rotates to adjust the swing frequency of the child seat 20 of the swing chair 1 to the maximum, the abutting flange abuts against one of the stop flanges, and the stop flange plays a limiting role on the abutting flange, so as to effectively reduce the possibility that the speed control knob 14 connected to the abutting flange is damaged due to excessive rotation.
