[0023] In the technical solution of this utility model, the armrest assembly mainly includes the armrest body and the armrest seat. The armrest seat is used to be detachably installed on the bracket of the child vehicle. When the armrest seat is installed on the bracket of the child vehicle, the armrest body installed on the armrest seat is supported and fixed. On the one hand, it is used for the child to place his / her hands, and on the other hand, it surrounds the front of the seat to play a protective role. When the armrest seat is removed from the bracket of the child vehicle, it is convenient for the user to place the child on the child vehicle and remove the child from the child vehicle, thus meeting the functional requirements. Specifically, the armrest seat includes a seat body with a guide groove extending in a first direction. The guide groove corresponds to a mounting base on the child vehicle bracket. One end of the guide groove is open, allowing the mounting base to extend into the guide groove through the opening. The contact between the mounting base and the groove wall of the guide groove limits the position of the seat body. A locking part is provided within the guide groove, and a mating part is provided on the mounting base. The locking part and the mating part engage to prevent the mounting base from dislodging from the guide groove, thereby locking the mounting base within the guide groove. This locks the seat body onto the child vehicle bracket, completing the installation of the armrest assembly on the child vehicle. When it is necessary to disassemble the armrest assembly, the operation is reversed: the locking part is disengaged from the mating part, and then the seat body is moved in the first direction, causing the mounting base to move out of the guide groove. This separates the seat body from the mounting base, thereby separating the armrest assembly from the child carrier bracket and achieving disassembly of the armrest assembly. This design satisfies the installation and disassembly functions while maintaining a simple structure, convenient operation, and high stability. Attached Figure Description

[0041] Currently, stroller seats are equipped with a front armrest that wraps around the front of the seat. This serves two purposes: firstly, it allows the baby to place their hands while sitting in the seat, and secondly, it prevents the baby from falling forward from the seat, thus providing a safety protection function. However, the front armrest can also be an obstacle when placing the baby in or removing them from the seat. Therefore, it is necessary to have a detachable or adjustable front armrest.

[0042] In view of this, the present invention proposes a handrail assembly, please refer to [link / reference]. Figures 1 to 10 The following is an embodiment of the handrail assembly proposed in this application. The handrail assembly will be described in detail below with reference to the specific drawings.

[0043] Please see Figures 1 to 10The armrest assembly 100 includes an armrest body 1 and armrest seats 2 disposed at both ends of the armrest body 1. The armrest seat 2 includes a base 21, on which a guide groove 211 extending in a first direction is provided, and the guide groove 211 is open at one end 2111 in the first direction. The guide groove 211 is used to cooperate with the mounting base 2011 on the bracket 200 of the child carrier 1000, so that the mounting base 2011 extends into the guide groove 211 from the opening 2111 to limit the armrest seat 2. A locking part 2112 is provided in the guide groove 211, and the locking part 2112 is used to cooperate with the mating part 2012 on the mounting base 2011 to position and lock the armrest seat 2.

[0044] In the technical solution of this utility model, the armrest assembly 100 mainly includes the armrest body 1 and the armrest seat 2. The armrest seat 2 is detachably installed on the bracket 200 of the child carrier 1000. When the armrest seat 2 is installed on the bracket 200 of the child carrier 1000, the armrest body 1 installed on the armrest seat 2 is supported and fixed. On the one hand, it is used for the child to place his / her hands, and on the other hand, it surrounds the front of the seat to play a protective role. When the armrest seat 2 is removed from the bracket 200 of the child carrier 1000, it is convenient for the user to place the child on the child carrier 1000 and remove the child from the child carrier 1000, thus meeting the functional requirements. Specifically, the armrest seat 2 includes a seat body 21, on which a guide groove 211 extending in a first direction is provided. The guide groove 211 corresponds to the mounting base 2011 on the child carrier 1000 bracket 200. One end of the guide groove 211 is open 2111, allowing the mounting base 2011 to extend into the guide groove 211 through the opening 2111. The contact between the mounting base 2011 and the groove wall of the guide groove 211 limits the positioning of the seat body 21. The locking part 2112 is provided in the guide groove 211, and the mating part 2012 is provided on the mounting base 2011. The locking part 2112 and the mating part 2012 cooperate to prevent the mounting base 2011 from coming out of the guide groove 211, thereby positioning and locking the mounting base 2011 in the guide groove 211, so that the seat 21 is positioned and locked on the bracket 200 of the child carrier 1000, and the armrest assembly 100 is installed on the child carrier 1000. When it is necessary to disassemble the armrest assembly 100, the operation is reversed: the locking part 2112 is disengaged from the mating part 2012, and then the seat 21 is moved in the first direction, causing the mounting base 2011 to move out of the guide groove 211. This separates the seat 21 from the mounting base 2011, thereby separating the armrest assembly 100 from the child carrier 1000 bracket 200, and thus disassembling the armrest assembly 100. This design satisfies the installation and disassembly functions while being simple in structure, convenient in operation, and highly stable.

[0045] It is understood that since each end of the armrest body 1 is provided with an armrest seat 2, the two armrest seats 2 are respectively positioned and locked onto a bracket 200 on the child carrier 1000. Generally, the two armrest seats 2 are installed on the opposite side or opposite side of the two brackets 200 of the child carrier 1000 in the second direction. That is, the two brackets 200 sandwich the armrest assembly 100 between them, or the two armrest seats 2 of the armrest assembly 100 sandwich the two brackets 200 of the child carrier 1000 between them. With this configuration, the opening of the guide groove 211 faces the second direction, so that no limiting structure is required in the guide groove 211. The mounting base 2011 will not move out of the guide groove 211 along the second direction from the opening of the guide groove 211, but can only extend into or out of the guide groove 211 from the opening 2111 of the guide groove 211 along the first direction. However, such a setting is obviously not entirely stable. Therefore, in this embodiment, a limiting protrusion is still provided at the opening of the guide groove 211. Specifically, the limiting protrusion is provided on both sides of the guide groove 211, and the two limiting protrusions are spaced apart by a clearance gap. This allows the mounting base 2011 to be limited in the second direction by the limiting protrusion and the bottom of the guide groove 211 after it extends into the guide groove 211 from the opening 2111. This limits the mounting base 2011 to be confined within the guide groove 211, while the clearance gap avoids the connection between the mounting base 2011 and the bracket 200, thus ensuring the stability of the mounting base 2011 after it extends into the guide groove 211.

[0046] Furthermore, the structure of the locking part 2112 and the mating part 2012 is not specifically limited, as long as they can satisfy the function of positioning and locking the seat 21 to the bracket 200 of the child carrier 1000. For example, it can be a pin structure, a snap-fit ​​structure, or a screw structure. In this embodiment, a snap-fit ​​structure is used, that is, one of the locking part 2112 and the mating part 2012 is set as the locking hole, and the other is set as the locking post. The mounting base 2011 extends into the guide groove 211 in the first direction until the locking hole and the locking post are aligned. At this point, the locking post extends into the locking hole, restricting the movement of the mounting base 2011 relative to the guide groove 211 in the first direction, thus satisfying the functional requirements. In addition, when the locking part 2112 is set as the locking hole, the locking hole is opened in the guide groove 211; and when the locking part 2112 is set as the locking post, the locking post protrudes from the groove wall of the guide groove 211.

[0047] Child carriers 1000 generally need to be designed with a foldable structure for easy storage when not in use or during travel, saving space. While this application designates the armrest assembly 100 as a detachable structure, allowing it to be disassembled and stored when the child carrier 1000 is folded, the disassembled armrest assembly 100 is obviously independent of the main body of the child carrier 1000. This makes it easy to lose and also prevents it from moving synchronously, making it inconvenient to operate. Therefore, this application designs the armrest assembly 100 as a foldable structure, and the folding method is not limited. For example, the armrest assembly 100 can be configured as multiple detachable components, connected by connectors to form a single unit. In a typical child vehicle 1000, multiple components are disassembled when the vehicle needs to be folded, and reassembled when the vehicle needs to be reused to meet functional requirements. In this embodiment, the folding structure of the armrest assembly 100 is designed with a rotational folding method. Specifically, the armrest seat 2 also includes a rotating seat 22, which is rotatably mounted on the seat body 21 around a second direction axis. The armrest body 1 is disposed on the rotating seat 22. With this configuration, when folding is required, the armrest body 1 can be rotated along with the rotating seat 22 to fold to one side of the bracket 200 of the child vehicle 1000, thus eliminating the need to remove the armrest assembly 100 and meeting functional requirements.

[0048] Specifically, the connection method between the armrest body 1 and the rotating seat 22 can be set according to specific needs, and is not specifically limited here. In this embodiment, it is proposed that the rotating seat 22 can be integrally formed with the armrest body 1 so that the rotating seat 22 and the armrest body 1 are a whole, thereby reducing the number of parts, reducing assembly steps, and reducing the possibility of users losing parts. In addition, it is proposed that the armrest body 1 can be detachably set to the rotating seat 22, so as to meet the situation where users need to disassemble the armrest body 1 separately when using it, including but not limited to disassembly and replacement after damage, avoiding the replacement of the entire armrest assembly 100, reducing maintenance and replacement costs, and meeting customized replacement needs, such as replacing the armrest body 1 with different colors, different materials, or even different functional components according to children's preferences, to meet more feasible needs.

[0049] Based on the rotating seat 22 rotatably mounted on the seat body 21 as described above, the rotating seat 22 has at least two position states. One is a position where it is positioned on the seat body 21, supporting the armrest body 1 so that the armrest body 1 can surround the child being seated and support the weight of the child's hands, providing a stable grip for the child. The other is a position where the armrest body 1 is folded close to the bracket 200. After the armrest body 1 is folded, it can be limited by other folding structures of the child carrier 1000, so a positioning setting is not necessarily required. It is a state where a positioning structure can be set or not. The actual setting depends on functional requirements. However, when the armrest body 1 surrounds the child and supports the child's hands, the rotating seat 22 must be positioned to maintain the position of the armrest body 1. To ensure its support reliability, the positioning of the rotating seat 22 can be achieved by setting a positioning structure between the rotating seat 22 and the seat body 21, or by setting a positioning structure between the rotating seat 22 and the bracket 200 of the child carrier 1000. The specific setting form of the positioning structure is not limited, and the actual structural setting requirements should be the main consideration to meet the above functional requirements. In this embodiment, an anti-rotation part 221 is provided at a position away from the rotation axis of the rotating seat 22. The anti-rotation part 221 is used to cooperate with the anti-rotation member 2013 that can be movably set on the bracket 200, so that the rotating seat 22 can be positioned on the bracket 200 of the child carrier 1000, passing through the seat body 21 structure, so that the positioning limit between the armrest body 1 and the child carrier 1000 is more stable, ensuring its reliability as a support and protection structure. In addition, to facilitate the rotation of the rotating seat 22 from its folded state onto the seat body 21, or to ensure the stability of the rotating seat 22 in its folded state, this embodiment also provides an elastic element between the rotating seat 22 and the seat body 21. By setting the force storage direction of the elastic element, one of the above functions can be achieved. The specific function selection is based on actual needs, so the specific structural setting of the elastic element is based on actual needs and is not limited here. The aim is to improve the user experience of the child vehicle 1000 by setting the elastic element.

[0050] Please see Figures 1 to 9 This application also proposes a child vehicle 1000, wherein the child vehicle 1000 includes a support 200 and a handrail assembly 100. The support 200 includes a first support rod 201 extending along a first direction. A mounting base 2011 is provided on the first support rod 201, and a mating part 2012 is provided on the mounting base 2011. The specific structure of the handrail assembly 100 is as described in the above embodiments. Since the child vehicle 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] After the mounting base 2011 extends into the guide groove 211, the positioning and fixing of the handrail assembly 100 by the cooperation of the locking part 2112 and the mating part 2012 has been described in detail above and will not be repeated here. Specifically, one of the locking part 2112 and the mating part 2012 is set as a locking post, and the other is set as a locking hole, so as to fix the handrail assembly 100 to the first support rod 201 by snap-fit ​​limiting. When the mounting base 2011 extends into the guide groove 211 from the opening 2111, the locking post is snapped into the locking hole to position and lock the handrail seat 2.

[0052] Specifically, the armrest seat 2 includes a seat body 21 and a rotating seat 22. The seat body 21 is provided with a guide groove 211. The rotating seat 22 is rotatably mounted on the seat body 21 about a second direction axis. The armrest body 1 is disposed on the rotating seat 22. The rotating seat 22 is provided with an anti-rotation part 221. The first support rod 201 is also provided with an anti-rotation member 2013 corresponding to the anti-rotation part 221. The anti-rotation part 221 can cooperate with the anti-rotation member 2013 to prevent the rotating seat 22 from rotating. The anti-rotation part 221 can disengage from the anti-rotation member 2013, so that the rotating seat 22 can move relative to the first support rod 201. The armrest assembly 100, when providing support around a child, requires positioning and fixation, as described in detail above, and will not be repeated here. Specifically, the rotating seat 22 is provided with the anti-rotation part 221, and the first support rod 201 is provided with the anti-rotation member 2013. The anti-rotation member 2013 cooperates with the anti-rotation part 221 to restrict the rotation of the armrest assembly 100. The specific cooperation structure between the anti-rotation member 2013 and the anti-rotation part 221 is not limited, as long as it satisfies the above-mentioned anti-rotation function. That is, the anti-rotation member 2013 and the anti-rotation part 221 can be set as relatively elastically deformable structures, and the rotation is restricted at a certain point. The locking mechanism at a specific location restricts the rotation of the handrail assembly 100, while allowing free rotation at other locations. In this embodiment, an anti-rotation portion 221 is provided on the rotating seat 22 away from its rotation axis. The first support rod 201 is also provided with an anti-rotation member 2013 corresponding to the anti-rotation portion 221, and the anti-rotation member 2013 is movably disposed on the first support rod 201, allowing it to have an anti-rotation position extending out of the first support rod 201 and a release position retracting into the first support rod 201. The anti-rotation member 2013 in the anti-rotation position can cooperate with the anti-rotation portion 221 to prevent the rotating seat 22 from rotating. By movably disposing the anti-rotation member 2013, the cooperation state between the anti-rotation member 2013 and the anti-rotation portion 221 can be adjusted, allowing the handrail assembly 100 to switch between a fixed positioning state and a rotationally unlocked state, thus meeting functional requirements.Specifically, the specific position of the anti-rotation part 221 on the rotating seat 22 is not limited. That is, the anti-rotation part 221 can be positioned at the axis of rotation of the rotating seat 22, and the rotation of the rotating seat 22 can be directly restricted by the corresponding anti-rotation member 2013. In this embodiment, the anti-rotation part 221 is positioned away from the axis of rotation of the rotating seat 22, so that after the anti-rotation member 2013 cooperates with the anti-rotation part 221, it can restrict the rotation of the anti-rotation part 221 around the axis of rotation of the rotating seat 22, thereby restricting the rotation of the rotating seat 22. Based on this, The anti-rotation component 2013 and the anti-rotation part 221 can be a pin connection structure, that is, the anti-rotation part 221 is set as an anti-rotation hole on the rotating seat 22, and the anti-rotation component 2013 is set as an anti-rotation pin. When the anti-rotation pin extends out of the first support rod 201 and into the anti-rotation hole, it can limit and fix the rotating seat 22. When the anti-rotation pin retracts into the first support rod 201, the anti-rotation pin disengages from the anti-rotation hole, thereby unlocking the rotation of the rotating seat 22 on the seat body 21 and realizing the switching of the armrest assembly 100 between the rotating and locked states.

[0053] It is understood that the seat 21 is installed by cooperating with the mounting base 2011 through the guide groove 211, that is, the seat 21 is set close to the bracket 200. At the same time, the rotating seat 22 is rotatably mounted on the seat 21 around the second direction axis. Therefore, the seat 21 is located between the bracket 200 and the rotating seat 22. The anti-rotation part 221 and the anti-rotation member 2013 are respectively located between the rotating seat 22 and the bracket 200. Therefore, the cooperation of the anti-rotation part 221 and the anti-rotation member 2013 needs to pass through the structure of the seat 21. Based on this, the anti-rotation part 221 and the anti-rotation member 2013 can be set at a position away from the seat 21 to prevent rotation. The structure of the seat 21 can be designed to avoid interference, or the structure can be positioned corresponding to the seat 21. That is, a clearance area can be created on the seat 21 to avoid interference between the anti-rotation part 221 and the anti-rotation member 2013. In this embodiment, the anti-rotation part 221 and the anti-rotation member 2013 are positioned corresponding to the seat 21 so that the seat 21 can cover the anti-rotation part 221 and the anti-rotation member 2013, preventing them from being exposed when they are in contact. This avoids the exposed anti-rotation part 221 and the anti-rotation member 2013 from causing harm to the child riding in the seat. Based on this, a through hole is provided on the base 21 to allow the anti-rotation member 2013 to pass through and extend into the anti-rotation part 221 for engagement. Furthermore, the size of the guide groove 211 is set to be relatively large. When the mounting base 2011 extends into the guide groove 211 and the locking part 2112 engages with the mating part 2012, i.e., when the mounting base 2011 is confined within the guide groove 211, there is an empty area at the end of the guide groove 211 away from the opening 2111. That is, the mounting base 2011 cannot extend into this area. Therefore, the through hole is provided in this area to avoid interference with the mounting base. The engagement between the base 2011 and the guide groove 211 creates an obstruction, while the anti-rotation member 2013 extending from the first support rod 201 can also move along the guide groove 211 to the corresponding through hole, so as to avoid the anti-rotation member 2013 extending from the first support rod 201 from blocking the seat 21 installed on the first support rod 201. At the same time, the seat 21 can be installed on the first support rod 201 and the anti-rotation member 2013 can be inserted into the through hole in one installation action, without having to operate the anti-rotation member 2013 to retract into the first support rod 201 when the seat 21 is installed, thus simplifying the operation.

[0054] The above mainly describes the detachable structure of the armrest assembly 100 and the first support rod 201. Based on the above detachable structure, a structure is proposed in which the anti-rotation part 221 on the rotating seat 22 cooperates with the anti-rotation member 2013 on the bracket 200. The cooperation of the anti-rotation part 221 and the anti-rotation member 2013 restricts the rotation of the armrest body 1 with the rotating seat 22, thereby providing hand support for children riding in the child carrier 1000. Based on this, it can be understood that in the design of existing child carriers 1000, in order to facilitate carrying and storage, the child carrier 1000 is usually set as a foldable structure, as described above. However, in actual use, this folding mechanism often requires sequentially folding multiple independent components. The folding process requires multiple steps, which not only complicates the user's operation but also reduces portability. Referring to the child carrier 1000 proposed in this application, the operation of engaging and disengaging the anti-rotation part 221 and the anti-rotation member 2013 is generally independent of the folding process of the bracket 200 of the child carrier 1000. It is necessary to operate the anti-rotation part 221 and the anti-rotation member 2013 separately when the child carrier 1000 is folded, which is complicated and reduces portability. In view of this, this application also proposes a linkage structure to automatically drive the anti-rotation part 221 and the anti-rotation member 2013 to disengage when the child carrier 1000 is folded, thereby solving the above problems and simplifying the overall folding operation of the child carrier 1000.At this point, it is understood that the function of the aforementioned linkage structure is clear: when the child carrier 1000 is folded, it drives the anti-rotation part 221 to disengage from the anti-rotation member 2013. The specific structural configuration can be varied and is not limited here. While the use of an electronic control method has less dependence on the structure, the child carrier 1000 is generally a non-electronic structure, making an electronic control method impractical. Therefore, this embodiment proposes a linkage structure between the rotating shaft of the bracket 200 and the anti-rotation member 2013. Through the folding and rotation of the bracket 200, the anti-rotation member 2013 is driven... 013 The movement continues until it disengages from the anti-rotation part 221, satisfying the functional requirements. Specifically, in this embodiment, the bracket 200 includes two second support rods 202 and a first support rod 201. The two second support rods 202 are rotatably connected around a second direction axis and can rotate closer to each other for folding. Each of the two second support rods 202 has a support section 2021. The two support sections 2021 extend from the rotation point of the two second support rods 202 in a direction away from each other in a first direction. This is the main structure of the bracket 200. The first support rod 201 is mainly used for support and manual support by the user, while the second support rod 202 is mainly used for stable support and contact with the ground. The first support rod 201 is connected to the rotating parts of the two second support rods 202. Based on the structural arrangement of the first support rod 201 and the second support rods 202, this embodiment provides a linkage component 2014 on the first support rod 201, and a driving component 203 is provided at the rotating parts of the two second support rods 202. One end of the linkage component 2014 is connected to the anti-rotation component 2013. The other end is connected to the drive member 203 for transmission. When the two second support rods 202 rotate, the drive member 203 can drive the linkage member 2014 to move, thereby causing the anti-rotation member 2013 to move and retract into the first support rod 201. This allows the anti-rotation member 2013 to disengage from the anti-rotation part 221, completing the unlocking of the rotating seat 22. This allows the rotating seat 22 and the armrest body 1 to rotate automatically under gravity in sync. Combined with the overall folding steps of the child carrier 1000, no additional operation is required, thus meeting the functional requirements.

[0055] Furthermore, the specific structures of the linkage 2014 and the driving member 203 are not limited. For example, they can be a linkage structure, with the driving member 203 positioned on one side of the rotation axis of the second support rod 202. This allows the driving member 203 to move relative to the anti-rotation member 2013 in a first direction as the driving member 203 rotates with the second support rod 202. This relative movement is used to drive the anti-rotation member 2013 back to the first support rod 201 through the linkage 2014 and the transmission structure, thereby releasing the engagement between the anti-rotation member 2013 and the anti-rotation part 221. Alternatively, a traction structure can be used, where the driving member 203 is wound around the second support rod 202 as the second support rod 202 rotates. The driving member 203 then pulls the linkage 2014, and the transmission structure between the linkage 2014 and the anti-rotation member 2013 drives the linkage 2014, achieving the purpose of driving the linkage 2014. In this embodiment, a driving surface 2031 is provided on the outer periphery of the driving member 203 located at the rotation point of the second support rod 202. The driving surface 2031 abuts against one end of the linkage member 2014, and the distance between the driving surface 2031 and the rotation axis of the driving member 203 is gradually changed. When the second support rod 202 is folded, the linkage member 2014 moves along the driving surface 2031 during the rotation of the driving member 203, moving towards or away from the rotation axis of the driving member 203. Combined with the linkage member 2014 being telescopically mounted on the first support rod 201 along the length direction of the first support rod 201, that is, the linkage member 2014 telescopically moves along the extension direction of the first support rod 201, and then through the transmission connection between the first support rod 201 and the anti-rotation member 2013, the anti-rotation member 2013 is retracted into the first support rod 201 to disengage from the anti-rotation part 221. In short, in the embodiments proposed in this application, during the rotation and folding process of the first support rod 201 and the second support rod 202, the driving member 203 drives the linkage member 2014 to extend and retract along the first support rod 201, thereby driving the anti-rotation member 2013 to move from the anti-rotation position to the loosened position, thus satisfying the functional requirements.

[0056] The above describes the driving structure details between the driving member 203 and the linkage member 2014. Regarding the structural details between the linkage member 2014 and the anti-rotation member 2013, this embodiment proposes that the anti-rotation member 2013 has a driving engagement portion 2013a facing the rotating seat 22, and the side surface of the other end of the linkage member 2014 is formed with a driving portion 2014a that abuts against the driving engagement portion 2013a; wherein, one of the driving engagement portion 2013a and the driving portion 2014a is provided with a driving inclined surface, so that when the linkage member 2014 moves away from the driving member 203, the anti-rotation member 2013 is driven to move away from the rotating seat 22. It is understood that the linkage 2014 is disposed within the first support rod 201 and extends and retracts along the extension direction of the first support rod 201, that is, it extends and retracts along the axial direction of the first support rod 201. The anti-rotation member 2013 is disposed within the first support rod 201 and can extend and retract radially along the first support rod 201. Thus, the transmission structure between the linkage 2014 and the anti-rotation member 2013 needs to redirect the power direction. Simply put, this embodiment uses a combination of the drive unit 2014a and the drive inclined surface to solve the power steering problem, which is simple in structure, low in cost, and effective.

[0057] To further simplify operation, this embodiment also provides an elastic reset member 2015 between the drive engagement part 2013a and the first support rod 201. The elastic reset member 2015 is used to reset the anti-rotation member 2013 from the loosened position to the anti-rotation position. Thus, when the folded child carrier 1000 is unfolded for use, the two second support rods 202 reopen. At this time, the linkage 2014 is no longer supported by the drive member 203, causing the elastic reset member 2015 to drive the linkage 2014 to move towards the drive member 203, thereby releasing the drive on the anti-rotation member 2013. At this time, the anti-rotation member 2013 can be extended out of the first support rod 201 again by the drive of the elastic reset member 2015. Then, by rotating the rotating seat 22, the anti-rotation part 221 on the rotating seat 22 can engage with the anti-rotation member 2013 to complete the unfolding of the armrest assembly 100. Thus, the step of the anti-rotation member 2013 extending out of the first support rod 201 is driven by the elastic reset member 2015, which eliminates the need for manual operation, simplifies the operation, and makes it easy to use.
