[0002] A child seat is a product designed to support a child's weight and help them sit or lie down more comfortably. Child seats are typically mounted on a frame that allows the child to move, thus forming a vehicle such as a stroller.

[0003] However, existing seats are designed to be fixedly attached to the frame as their default working state. Their overall function is limited by the support and constraints provided by the frame. In other words, the seat cannot be used independently without the frame. This results in the seat having limited functionality and application scenarios, making it difficult to flexibly adapt to changing caregiving needs. Utility Model Content

[0004] The main purpose of this utility model is to propose a seat assembly that aims to solve the technical problems of existing seats being unable to be used independently without being removed from the frame, having relatively limited functionality, and being limited in application scenarios.

[0005] To achieve the above objectives, the present invention provides a seat assembly comprising:

[0006] The seat body is designed for detachable attachment to the base frame;

[0007] The support member is detachably or movably connected to the seat body; when the support member is connected to the seat body or moves relative to the seat body to a target position, the end of the support member and the bottom of the seat body together form a ground support structure.

[0008] In one embodiment, the support member is rotatably connected to the seat body; when the support member is rotated to a first position, the end of the support member is folded onto the seat body; when the support member is rotated to a second position, the end of the support member is unfolded relative to the seat body, so that the end of the support member and the bottom of the seat body together constitute the ground support structure.

[0009] In one embodiment, the seat assembly further includes a limiting member disposed on the seat body or the support member, the limiting member being used to hold the support member in the first position or the second position.

[0010] In one embodiment, the limiting member includes a hook structure disposed on the seat body; when the support member rotates to the first position or the second position, the end of the support member is engaged with the hook structure.

[0011] In one embodiment, the seat body includes a main frame, and the support member is rotatably connected to the main frame;

[0012] When the support member is rotated to the first position, the end of the support member is folded into the upper or lower frame portion of the main frame; when the support member is rotated to the second position, the end of the support member and the lower frame portion together form the ground support structure.

[0013] In one embodiment, the support member includes a first vertical rod segment, a second vertical rod segment, and a transverse rod segment; the first end of the first vertical rod segment is rotatably connected to the left side of the seat body about a first axis, the first end of the second vertical rod segment is rotatably connected to the right side of the seat body about the first axis, the first end of the transverse rod segment is connected to the second end of the first vertical rod segment, and the second end of the transverse rod segment is connected to the second end of the second vertical rod segment.

[0014] In one embodiment, the seat body further includes a seat portion and a backrest, the seat portion being connected to the lower side frame portion, and the backrest being rotatably connected to the upper side frame portion; when the support member rotates to the first position or the second position, the backrest rotates relative to the upper side frame portion to adjust the leaning angle of the backrest.

[0015] In one embodiment, the support member is rotatably connected to the middle of the main frame.

[0016] In one embodiment, when the support member is rotated to the first position, the support member is folded into the upper frame portion, and the upper end of the support member is flush with or protrudes from the upper end of the upper frame portion.

[0017] In one embodiment, the first vertical segment, the second vertical segment, and the horizontal segment are integrally bent into shape.

[0018] In one embodiment, the transverse bar segment is provided with a clearance structure, which is recessed inward along a direction close to the first axis.

[0019] In one embodiment, the seat body further includes a canopy support rod, which is rotatably connected to the main body frame.

[0020] In one embodiment, the seat body further includes an armrest connected to the main body frame.

[0021] In one embodiment, the seat body further includes a connector disposed in the middle of the main frame, the connector being detachably connected to the mating parts of the base frame.

[0022] The present invention also proposes a carrier, the carrier including a base frame and a seat assembly as described above; the seat body of the seat assembly is detachably connected to the base frame.

[0023] The proposed saddle assembly adds a detachable or movable support component to the existing saddle body. When the saddle body needs to be placed on the base frame for use as a regular saddle, the support component can be removed from the saddle body, or moved or rotated relative to the saddle body to a position that does not interfere with the installation of the saddle body, so as not to affect the connection and fixation between the saddle body and the base frame, allowing the saddle body to be normally installed on the base frame and used as a regular saddle. After the saddle body is removed from the base frame, the support component can be reconnected to the saddle body, or moved or rotated relative to the saddle body to the target position. At this time, the end of the support component and the bottom of the saddle body are in contact with the ground to form a ground support structure, thus forming an independent support function. This allows the saddle assembly to be placed stably on the ground without relying on the base frame for use as a swaddle, ensuring that the infant can lie safely in the saddle body, solving the problem of holding the infant without a base frame, and reducing the burden on the person holding the infant.

[0024] Therefore, the seat assembly provided by this utility model can flexibly switch between two usage states, thereby expanding the function of traditional seat and making the seat more suitable for different application scenarios. Attached Figure Description

[0038] A child seat is a product designed to support a child's weight and help them sit or lie down more comfortably. Child seats are typically mounted on a frame that allows the child to move, thus forming a vehicle such as a stroller.

[0039] However, existing seats are designed to be fixedly attached to the frame as their default working state. Their overall function is limited by the support and constraints provided by the frame. In other words, the seat cannot be used independently without the frame. This results in the seat having limited functionality and application scenarios, making it difficult to flexibly adapt to changing caregiving needs.

[0040] To address the aforementioned issues, this invention provides a seat assembly that adds a detachable or movable support member to the existing seat body. When the seat body is to be placed on the frame for use as a regular seat, the support member can be removed from the seat body or rotated relative to the seat body to a folded state, without affecting the connection and fixation between the seat body and the frame. After the seat body is removed from the frame, the support member can be installed on the seat body or rotated relative to the seat body to an unfolded state, thus forming an independent support function in conjunction with the seat body. This allows the seat assembly to be stably placed on the ground without relying on the frame and used as a swaddle. Based on the above design, the seat can flexibly switch between two usage states, thereby expanding the functionality of the traditional seat and making it more suitable for different application scenarios.

[0041] Please see Figures 1 to 4 The seat assembly provided in this embodiment of the present invention includes:

[0042] The seat body 1 is detachably connected to the base frame;

[0043] The support member 2 is detachably or movably connected to the seat body 1; when the support member 2 is connected to the seat body 1 or moves relative to the seat body 1 to the target position, the end of the support member 2 and the bottom of the seat body 1 together form a ground support structure.

[0044] In this embodiment, the seat body 1 can be an existing seat; the seat body 1 has an upward-facing accommodating space, in which a liner, cushion, quilt, etc. can be placed for the infant to lie down.

[0045] The term "base frame" can refer to the main body of any vehicle with a walking function, such as the frame of a baby stroller or a baby walker, and is not limited here.

[0046] The detachable connection between the seat body 1 and the base frame can be achieved using any quick-release structure. Specifically, a pin can be installed on the seat body 1, which slides into a slot on the base frame. Once the pin is inserted into the slot, it can be automatically locked by a spring-loaded latch. Alternatively, a buckle can be installed on the seat body 1 to fasten and fix it to structures such as crossbeams, rods, and connecting slots on the base frame. A magnetic-mechanical composite interface can also be used between the seat body 1 and the base frame. First, the magnetic attraction of the device achieves pre-positioning between the seat body 1 and the base frame, and then the mechanical buckle secures the seat body 1 to the base frame. All of these methods enable quick installation and removal of the seat body 1 from the base frame. The specific configuration can be flexibly chosen as needed in specific applications and is not limited here.

[0047] Support component 2 can be a rod-shaped, plate-shaped, or frame-shaped component, as long as it has a supporting function.

[0048] In one embodiment, the support member 2 is detachably connected to the seat body 1. Specifically, a pin can be provided on the support member 2, which slides into a corresponding slot on the seat body 1. When the pin is inserted into the slot, it can be automatically locked by a resilient locking tongue. Alternatively, a buckle can be provided on the support member 2 to fasten and fix it to structures such as crossbeams, rods, and connecting grooves on the seat body 1. A magnetic-mechanical composite interface can also be provided between the support member 2 and the seat body 1. First, the magnetic attraction of the support member 2 and the seat body 1 is used to achieve pre-positioning between them, and then the mechanical locking is used to finally fix them together. All of the above methods can achieve quick installation and removal of the support member 2 from the seat body 1. These methods can be flexibly configured as needed in specific applications and are not limited here.

[0049] In another embodiment, the support member 2 is movably connected to the seat body 1. Specifically, the support member 2 can be slidably fitted onto the seat body 1 or rotatably connected to the seat body 1. Taking a rotatable connection as an example, the rotatable connection between the support member 2 and the seat body 1 can be achieved by any hinge mechanism or pivot mechanism that allows relative rotation between the two. For example, boss structures with shaft holes can be provided on the left and right side walls of the seat body 1, so that the upper end of the support member 2 can be pivotally fitted into the shaft hole. Alternatively, an integrally formed elastic hinge can be used to allow a direct flexible connection between the support member 2 and the seat body 1. Alternatively, any mechanism with rotational freedom, such as a ball joint or a flexible pivot, can be used, as long as the connection method allows the support member 2 to rotate relative to the seat body 1 around one or more axes.

[0050] In the embodiment where the support member 2 is detachably connected to the seat body 1, the end of the support member 2 can generally refer to any end portion of the support member 2 that is away from its mounting portion (i.e., the connection between the support member 2 and the seat body 1); in the embodiment where the support member 2 is movably connected to the seat body 1, the end of the support member 2 can generally refer to any end portion of the support member 2 that is away from the seat body 1 or away from its axis of rotation; the end of the support member 2 is not limited to the geometric endpoints of the support member 2. For example, for a long strip-shaped support member 2, its end can refer to its very end portion, or it can refer to a section of structure extending laterally inward from its very end portion; for a plate-shaped support member 2, its end can refer to the lower edge of the plate-shaped structure, or it can refer to a boss, notch, or other structure provided at the lower edge of the plate-shaped structure; for a multi-link support member 2, its end can refer to any joint or any contact block at the end of the link.

[0051] When the support member 2 is connected to the seat body 1 or moves to the target position relative to the seat body 1, the end of the support member 2 can contact the ground together with the bottom of the seat body 1, thus forming a ground support structure. A ground support structure generally refers to any support configuration that can ensure the seat body 1 remains stably stationary on the ground after detaching from the base frame; for example, the end of the support member 2 and the bottom of the seat body 1 can form a two-line support structure, a two-point-one-line support structure, a three-point support structure, etc. Furthermore, the support member 2 can directly contact the ground, or anti-slip pads, suction cups, telescopic structures, etc., can be added to its end to enhance ground adhesion or adapt to different ground flatness. As long as the final support structure can ensure that the seat body 1 is stably placed on the ground and remains stationary without the assistance of the base frame, it falls within the scope of a ground support structure.

[0052] Based on the above configuration, when the seat body 1 needs to be placed on the base frame for use as a regular seat, the support 2 can be removed from the seat body 1, or the support 2 can be moved or rotated relative to the seat body 1 to a position that does not interfere with the installation of the seat body 1, so as not to affect the connection and fixation between the seat body 1 and the base frame, allowing the seat body 1 to be normally installed on the base frame and used as a regular seat. After the seat body 1 is removed from the base frame, the support 2 can be reconnected to the seat body 1, or the support 2 can be moved or rotated relative to the seat body 1 to the target position. At this time, the end of the support 2 and the bottom of the seat body 1 are in contact with the ground to form a ground support structure, thus forming an independent support function, allowing the seat assembly to be placed stably on the ground without relying on the base frame for use as a swaddle, ensuring that the infant can lie safely in the seat body 1, solving the problem of holding the baby without a base frame, and reducing the burden on the person holding the baby.

[0053] Therefore, the seat assembly provided in this embodiment can flexibly switch between two usage states, thereby expanding the function of traditional seat and making the seat more suitable for different application scenarios.

[0054] In one embodiment, refer to Figures 1 to 4 The support member 2 is rotatably connected to the seat body 1. When the support member 2 is rotated to the first position, the end of the support member 2 is folded onto the seat body 1. When the support member 2 is rotated to the second position, the end of the support member 2 is unfolded relative to the seat body 1 so that the end of the support member 2 and the bottom of the seat body 1 together form a ground support structure.

[0055] Specifically, the rotatable connection between the support member 2 and the seat body 1 can be achieved by any hinge mechanism or pivot mechanism that allows relative rotation between the two. For example, a boss structure with a shaft hole can be provided on the left and right side walls of the seat body 1, so that the upper end of the support member 2 can be pivotally inserted into the shaft hole. Alternatively, an integrally formed elastic hinge can be used to make a direct flexible connection between the support member 2 and the seat body 1. Alternatively, any mechanism with rotational freedom such as a ball joint or flexible pivot can be used, as long as the connection method allows the support member 2 to rotate relative to the seat body 1 around one or more axes.

[0056] The first position and the second position correspond to two extreme rotation states of the support member 2 on the seat body 1, respectively. When the support member 2 rotates to the first position relative to the seat body 1, the support member 2 can move close to the seat body 1 as a whole, and the corresponding structure on the seat body 1 can be used to shield and store the approaching support member 2, so that the support member 2 is in a folded state relative to the seat body 1; for example, the support member 2 can be placed against the storage groove of the seat body 1, or the support member 2 can be embedded in the concave structure of the seat body 1, or the support member 2 can be temporarily fixed to the side wall of the seat body 1 by a retainer; the support member 2 in the folded state can be completely hidden within the outline of the seat body 1, or it can be partially exposed without affecting the connection between the seat body 1 and the frame. When the support member 2 rotates to the second position relative to the seat body 1, the support member 2 can move away from the seat body 1 as a whole and enter the unfolded state. At this time, the end of the support member 2 is in any downward extension posture relative to the seat body 1, such as vertically downward, tilted downward to the outside or tilted downward to the inside, etc., to form a support function.

[0057] Based on the above settings, when the seat body 1 needs to be placed on the base frame for use as a regular seat, such as Figure 1 and Figure 2 As shown, the support member 2 can be rotated relative to the seat body 1 to a first position, so that the support member 2 is in a fully or partially hidden folded state, so as not to affect the connection and fixation between the seat body 1 and the base frame; and after the seat body 1 is removed from the base frame, as Figure 3 and Figure 4 As shown, the support member 2 can be rotated relative to the seat body 1 to the second position, so that the support member 2 is in the unfolded state. At this time, the end of the support member 2 and the bottom of the seat body 1 are in contact with the ground to form a standing support structure. This can form an independent support function, so that the seat assembly can be placed stably on the ground without relying on the base frame, and can be used as a swaddle seat to ensure that the infant can lie safely in the seat body 1. This solves the problem of holding the baby without a base frame and reduces the burden on the person holding the baby.

[0058] In this embodiment, the support member 2 is rotatably connected to the seat body 1, so that the support member 2 and the seat body 1 are always bound together. This eliminates the need to carry the support member 2 separately, thereby improving the convenience of use.

[0059] In one embodiment, refer to Figures 1 to 4 The seat assembly also includes a limiting member (not shown in the figure), which is disposed on the seat body 1 or the support member 2, and is used to hold the support member 2 in a first position or a second position.

[0060] Specifically, the seat body 1 or the support member 2 may have only one limiting member corresponding to the first position. When the support member 2 rotates to the first position, the limiting member can fix the support member 2 to the seat body 1. The seat body 1 or the support member 2 may also have only one limiting member corresponding to the second position. When the support member 2 rotates to the second position, the limiting member can fix the support member 2 to the seat body 1. The seat body 1 or the support member 2 may also have two or more limiting members. One limiting member is used to fix the support member 2 rotated to the first position to the seat body 1, and the other limiting member is used to fix the support member 2 rotated to the second position to the seat body 1, so that the support member 2 can remain fixed relative to the seat body 1 in both postures.

[0061] The specific form of the limiting component can be a stop block, elastic hook, sliding lock tongue, rotary lock, magnetic adsorption seat or other releasable retaining structure. The triggering method of the limiting component can include interference fit, elastic self-locking, manual tossing, button pressing, magnetic release, etc. The locking surface of the limiting component can be a plane, curved surface or toothed surface, which can be flexibly set as needed in practical applications.

[0062] By setting a limiting component, the support component 2 can maintain a predetermined posture in both the folded and unfolded states, preventing unexpected rotation due to shaking or accidental contact, thereby improving the positional stability and safety of the seat assembly.

[0063] In one embodiment, refer to Figures 1 to 4 The limiting component includes a hook structure (not shown in the figure), which is set on the seat body 1; when the support member 2 rotates to the first position or the second position, the end of the support member 2 is fastened to the hook structure.

[0064] The hook structure can take different structural forms and can be configured individually or in combination at appropriate positions on the seat body 1 to fasten the support member 2 with its end when the support member 2 is in the first position and / or in the second position, thereby fixing the support member 2, and can release the support member 2 under the application of appropriate external force, so that the support member 2 leaves the first position and / or the second position.

[0065] Specifically, the hook structure can be an elastic hook, the opening direction of which is tangent to the movement trajectory of the end of the support member 2. The opening position of the elastic hook can be provided with a guide ramp and a check structure: when the end of the support member 2 enters the opening position of the elastic hook, the end of the support member 2 can be guided by the guide ramp to drive the check structure to undergo elastic deformation and slide into the end of the opening position. Subsequently, the check structure will elastically reset and block the end of the support member 2, preventing the end of the support member 2 from detaching from the end of the opening position, that is, forming a locking effect on the end of the support member 2. Afterwards, only a certain external force needs to be applied to the support member 2 in the opposite direction to drive the check structure to undergo elastic deformation and achieve displacement, allowing the end of the support member 2 to detach from the end of the opening position.

[0066] Based on the automatic fastening function of the hook structure, the end of the support member 2 can be fastened into the opening of the hook structure when it is rotated to the first position or the second position, without the need for additional manual locking operation, thereby improving the convenience of the support member 2 when performing folding and unfolding operations.

[0067] In one embodiment, refer to Figures 1 to 4 The seat body 1 includes a main frame 11, and the support member 2 is rotatably connected to the main frame 11;

[0068] When the support member 2 is rotated to the first position, the end of the support member 2 is folded into the upper or lower frame portion of the main frame 11; when the support member 2 is rotated to the second position, the end of the support member 2 and the lower frame portion together form a ground support structure.

[0069] Specifically, the main frame 11 can be set as a rectangular frame, an elliptical frame, etc., and the main frame 11 can be integrally formed or formed by welding pipes.

[0070] Taking the U-shaped structure of the support member 2 as an example, one end of the support member 2 can be hinged to the left frame segment of the main frame 11 via a pivot, and the other end of the support member 2 can be hinged to the right frame segment of the main frame 11 via another pivot; for example Figure 1 and Figure 2 As shown, when the support member 2 rotates upward relative to the main frame 11 to the first position, the support member 2 fits against the upper frame portion of the main frame 11. At this time, the support member 2 can be hidden behind the upper frame portion, and the upper frame portion can be provided with corresponding limiting members to lock the support member 2 in the current position; as shown Figure 3 and Figure 4 As shown, when the support member 2 rotates downward relative to the main frame 11 to the second position, the support member 2 is in the unfolded state. At this time, the horizontal rod segment 23 and the lower frame part of the main frame 11 together form a ground support structure, which can be used to stably place the seat assembly on the ground.

[0071] In one embodiment, refer to Figures 1 to 4 The support member 2 includes a first vertical rod segment 21, a second vertical rod segment 22, and a transverse rod segment 23. The first end of the first vertical rod segment 21 is rotatably connected to the left side of the seat body 1 around the first axis X1, the first end of the second vertical rod segment 22 is rotatably connected to the right side of the seat body 1 around the first axis X1, the first end of the transverse rod segment 23 is connected to the second end of the first vertical rod segment 21, and the second end of the transverse rod segment 23 is connected to the second end of the second vertical rod segment 22.

[0072] Illustrationly, the first vertical segment 21, the horizontal segment 23, and the second vertical segment 22 are connected in sequence to form a U-shaped structure; wherein, the first vertical segment 21, the horizontal segment 23, and the second vertical segment 22 can refer to each segment on the integrally formed support member 2, and the support member 2 can also be formed by connecting the independent first vertical segment 21, the second vertical segment 22, and the horizontal segment 23 by welding, pinning, threaded connection, etc., which is not limited here.

[0073] The upper ends of the first vertical rod segment 21 and the second vertical rod segment 22 can be hinged to the left and right frame segments of the main frame 11 respectively via the same pivot, or they can be hinged to different pivots to achieve synchronous rotation of the support member 2 on both sides of the seat body 1; the left and right ends of the transverse rod segment 23 are connected to the lower ends of the first vertical rod segment 21 and the second vertical rod segment 22 respectively, and the transverse rod segment 23 can serve as the end of the support member 2 in the above embodiment and contact the ground.

[0074] Based on the aforementioned U-shaped structure of support member 2, such as Figure 1 and Figure 2 As shown, when the support member 2 rotates upward relative to the main frame 11 to the first position, the support member 2 fits against the upper frame portion of the main frame 11. At this time, the support member 2 can be hidden behind the upper frame portion, and the upper frame portion can be provided with corresponding limiting members to lock the support member 2 in the current position; as shown Figure 3 and Figure 4 As shown, when the support member 2 rotates downward relative to the main frame 11 to the second position, the support member 2 is in the unfolded state. At this time, the horizontal rod segment 23 and the lower frame part of the main frame 11 together form a ground support structure, which can be used to stably place the seat assembly on the ground.

[0075] Based on the above-mentioned structural configuration of the support member 2, the support member 2 can maintain left and right synchronization during rotation, and can ensure the uniformity of force on the left and right sides in the unfolded support state. The transverse rod segment 23 can form a stable multi-point support structure together with the bottom of the seat body 1, thereby further improving the stability of the seat assembly on the ground when used as a swaddle.

[0076] In one embodiment, the seat body 1 further includes a seat portion (not shown in the figure) and a backrest (not shown in the figure). The seat portion is connected to the lower frame portion, and the backrest is rotatably connected to the upper frame portion. When the support member 2 is rotated to the first position or the second position, the backrest rotates relative to the upper frame portion to adjust the leaning angle of the backrest.

[0077] In this embodiment, the seat is connected to the lower frame of the seat body 1, aiming to provide stable sitting support for the user; the backrest is connected to the upper frame of the seat body 1 via a corresponding rotating mechanism. This rotating mechanism allows the backrest to be adjusted within a certain angle range to adapt to different sitting postures of the user, thereby providing more personalized comfort support. Specifically, the rotating mechanism of the backrest can adopt a ball-and-socket joint mechanism, a gear meshing mechanism, etc., to ensure the stability and reliability of the backrest during rotation adjustment.

[0078] In one embodiment, refer to Figures 1 to 4 When the support member 2 rotates to the first position, the support member 2 folds into the upper frame portion, and the upper end of the support member 2 is flush with or protrudes from the upper end of the upper frame portion.

[0079] Based on the arrangement of the support member 2 in this embodiment, when the support member 2 rotates upward and folds behind the upper frame, it can be ensured that the coverage area of ​​the support member 2 is located outside the main frame 11, that is, it can be ensured that the support member 2 does not enter the closed loop area formed by the main frame 11. In this way, the support member 2 can be prevented from interfering with the operation of the corresponding devices within the enclosed area of ​​the main frame 11 in the folded state. Specifically, the support member 2 can be prevented from interfering with the rotation adjustment operation of the backrest within the main frame 11 in the folded state.

[0080] In one embodiment, refer to Figures 1 to 4 The support member 2 is rotatably connected to the middle of the main frame 11. Based on this configuration, it is possible to ensure that the support member 2 can be properly folded behind the upper frame while avoiding the problem of insufficient support stability of the support member 2 for the seat body 1 in the unfolded state due to the low position of the rotation connection point between the support member 2 and the main frame 11.

[0081] In one embodiment, refer to Figures 1 to 4 The first vertical segment 21, the second vertical segment 22, and the horizontal segment 23 are integrally bent into shape.

[0082] Based on the above-mentioned integrated bending forming method, the weak points at the segmented connection on the support member 2 can be eliminated, and the bending operation itself can generate work hardening in the bending area, thereby increasing the yield strength and tensile strength of the local position, thus improving the structural strength and overall load-bearing capacity of the support member 2.

[0083] In one embodiment, refer to Figures 1 to 4 The transverse segment 23 is provided with a clearance structure 231, which is recessed inward along the direction close to the first axis X1.

[0084] In practical applications, the upper end of the seat body 1 is usually equipped with an operating device 15. The operating device 15 can be used to lock the backrest after it has been rotated and adjusted to the correct position relative to the upper frame, so that the backrest maintains the current leaning angle; when the operating device 15 releases the lock on the backrest, the backrest can continue to be rotated and adjusted. In addition, the operating device 15 can also be used to lock and unlock the folding and unfolding operations of the seat assembly.

[0085] When the support member 2 is rotated upward relative to the seat body 1 to achieve folding, by providing a clearance structure 231 on the transverse rod segment 23, a clearance effect can be formed when the support member 2 is rotated to the first position and close to the upper end of the seat body 1, which can prevent the transverse rod segment 23 from interfering with the operating device 15 at the upper end of the seat body 1.

[0086] In addition, when the first vertical segment 21, the second vertical segment 22 and the horizontal segment 23 are bent into one piece, the avoidance structure 231 can also be bent into one piece on the horizontal segment 23. In this way, the structural strength and overall load-bearing capacity of the support member 2 can be further improved by utilizing the reinforcement effect of the bending operation.

[0087] In one embodiment, refer to Figures 1 to 4 The seat body 1 also includes a canopy support rod 12, which is rotatably connected to the main frame 11.

[0088] In one embodiment, refer to Figures 1 to 4 The seat body 1 also includes an armrest 13, which is connected to the main frame 11.

[0089] In one embodiment, refer to Figure 1 The seat body 1 also includes a connector 14, which is located in the middle of the main frame 11. The connector 14 is used to detachably connect with the mating parts of the base frame (not shown in the figure).

[0090] Specifically, the canopy support rod 12 can be configured as follows: Figure 1 and Figure 3The U-shaped structure shown has the canopy support rod 12 hinged at both ends to the left and right sides of the main frame 11. A sunshade canopy can be installed on the canopy support rod 12 so that the sunshade canopy can be easily opened and closed by rotating the canopy support rod 12 relative to the main frame 11.

[0091] Handrail 13 can be set as follows Figure 1 and Figure 3 The U-shaped structure shown has two ends of the armrest 13 connected to the left and right sides of the main frame 11, respectively. The middle part of the armrest 13 can be held by infants and toddlers sitting or lying in the seat body 1 to ensure the balance of the infants and toddlers.

[0092] Two connectors 14 can be provided, and the two connectors 14 can be located on the left and right sides of the main frame 11 respectively; the mating parts can also be provided on the left and right sides of the base frame and connected to the connectors 14 one by one. The connectors 14 and the mating parts can adopt a detachable structure such as a pin engagement, a rotating buckle engagement, or a magnetic engagement to realize quick connection and disassembly between the seat body 1 and the base frame.

[0093] This utility model embodiment also provides a carrier, please refer to Figures 1 to 4 The vehicle includes a chassis (not shown in the figure) and a seat assembly as described in any of the above embodiments; the seat body 1 of the seat assembly is detachably connected to the chassis.

[0094] In this embodiment, the vehicle can be a stroller, a baby walker, or other tool with the function of carrying people and walking; the frame can refer to the main body of the vehicle, such as the frame of an infant stroller or the frame of a baby walker, etc., and is not limited here.

[0095] The detachable connection between the seat body 1 and the base frame can be achieved using any quick-release structure. Specifically, a pin can be installed on the seat body 1, which slides into a slot on the base frame. Once the pin is inserted into the slot, it can be automatically locked by a spring-loaded latch. Alternatively, a buckle can be installed on the seat body 1 to fasten and fix it to structures such as crossbeams, rods, and connecting slots on the base frame. A magnetic-mechanical composite interface can also be used between the seat body 1 and the base frame. First, the magnetic attraction of the device achieves pre-positioning between the seat body 1 and the base frame, and then the mechanical buckle secures the seat body 1 to the base frame. All of these methods enable quick installation and removal of the seat body 1 from the base frame.
