Description

Technical Field

[0001] This utility model belongs to the field of automotive armrest technology, specifically relating to an interlocking, two-sided flip-open armrest and automotive armrest box. Background Technology

[0002] The car armrest provides storage space, and the armrest itself, located above the armrest, serves to conceal and open it. Currently, car armrests typically feature a single- or double-sided opening design. While double-sided opening armrests are convenient for the driver and front passenger, they are less convenient for rear passengers. Furthermore, multi-sided opening armrests often have complex structures, and there is a risk of one side failing to return to its original position while the other is pressed open, causing the entire armrest to detach and compromising safety. Utility Model Content

[0003] The purpose of this utility model is to provide an interlocking, two-sided flip-open armrest and car armrest box to solve the problems of complex armrest structure, inconvenience for rear passengers, and safety issues.

[0004] This utility model is achieved through the following technical solution: Interlocking, flip-open armrests on both sides, including: The base assembly includes a base, a front bracket, and a rear bracket; The handrail assembly includes the handrail body, linkage mechanism, reset mechanism, opening mechanism, and interlocking mechanism; The linkage mechanism includes a left push plate, a right push plate, a left linkage assembly, a right linkage assembly, a rear linkage, and a first linkage turntable. The left push plate, the right push plate, the left linkage assembly, the right linkage assembly, and the rear linkage are slidably engaged with the handrail body. The left push plate and the right push plate are arranged laterally along the handrail body, and the rear linkage is arranged longitudinally along the handrail with one end extending to the rear end of the handrail body. The opening mechanism includes a front rotating arm and a rear rotating arm, which are hinged to the front and rear supports respectively on the same side of the handrail body. In the locked state, the left connecting rod assembly has its two ends inserted into the front and rear rotating arms, as well as the front and rear supports, respectively, and the right connecting rod assembly has its two ends inserted into the front and rear rotating arms respectively. The left push plate and the left connecting rod assembly, and the right push plate and the right connecting rod assembly, are in a transmission relationship. When the left and right push plates are pushed, the connection between the left connecting rod assembly and the front and rear supports, or between the right connecting rod assembly and the front and rear rotating arms, is released, allowing the handrail assembly to flip open to one side. The first connecting rod turntable is rotatably connected to the handrail body, and its two ends are hinged to the right connecting rod assembly and the rear connecting rod respectively, so that when the rear connecting rod moves, it can drive the right connecting rod assembly to the unlocked state via the first connecting rod turntable. The reset mechanism is used to provide a force that returns the left and right linkage assemblies from the unlocked state to the locked state. The interlocking mechanism includes a first limiting member that is connected to the left link assembly. When one of the left link assembly or the right link assembly is unlocked, the first limiting member and the first link turntable can form an abutment engagement to prevent the other of the left link assembly or the right link assembly from being unlocked.

[0005] In some embodiments of this utility model, the first limiting member is slidably engaged with the handrail body, enabling the first limiting member to move in a direction away from or towards the first connecting rod turntable, and the first limiting member is in a transmission engagement with the left connecting rod assembly. When the left linkage assembly is unlocked, the left linkage assembly can drive the first limiting member to move toward the first connecting turntable and abut against the first connecting turntable to restrict the rotation of the first connecting turntable; when the right linkage assembly is unlocked, the first connecting turntable rotates to abut against the first limiting member to restrict the movement of the first limiting member.

[0006] In some embodiments of this utility model, the interlocking mechanism includes an interlocking bracket and an interlocking spring. The interlocking bracket is provided with a triggering part and an interlocking part opposite to each other. The interlocking bracket is disposed on the handrail body near one end of the front bracket and is rotatably connected to the handrail body. The interlocking spring provides a force for the interlocking bracket to rotate, and the triggering part is limited to the front rotating arm to restrict the rotation of the interlocking bracket. When the armrest assembly is in the open position, the interlocking part rotates to a position that can restrict the movement of the left push plate, right push plate and rear linkage under the action of the interlocking spring and the front rotating arm. When the armrest assembly is in the closed state, the triggering part interacts with the front bracket, allowing the interlocking part to rotate to a position that releases the movement restrictions on the left push plate, right push plate, and rear linkage.

[0007] In some embodiments of this utility model, one end of the left push plate, the rear connecting rod, and the right push plate is arranged around the interlocking part, so that when the interlocking part rotates, it can enter the space enclosed by the ends of the left push plate, the rear connecting rod, and the right push plate and abut against the ends of the left push plate, the right push plate, and the rear connecting rod, or exit from the space enclosed by the ends of the left push plate, the rear connecting rod, and the right push plate.

[0008] In some embodiments of this utility model, the interlocking mechanism includes a locking component disposed on the interlocking bracket; When the handrail assembly is closed, the locking component can lock the left push plate, right push plate, or rear link in the unlocked position when the left push plate, right push plate, or rear link is pushed, keeping the left link assembly and right link assembly in the unlocked state; and when the handrail assembly is opened, the locking component rotates with the interlock bracket and releases the movement restriction on the left push plate, right push plate, or rear link.

[0009] In some embodiments of this utility model, the locking assembly includes a left locking member, a right locking member, and a rear locking member for locking the left push plate, the right push plate, and the rear connecting rod, respectively. The left locking member, the right locking member, and the rear locking member are rotatably connected at one end to the interlocking bracket. The left locking member, the right locking member, and the rear locking member are respectively provided with a spring between the interlocking bracket and the interlocking bracket, which enables them to rotate toward the side where the interlocking part is located.

[0010] In some embodiments of this utility model, the reset mechanism further includes a reset spring that can provide the left push plate and the right push plate with a reset spring that returns them from the unlocked position to the initial position.

[0011] In some embodiments of this utility model, a transmission column is provided on the rear connecting rod, and a transmission hole is provided at one end of the first connecting rod turntable. The transmission column extends into the transmission hole, and the size of the transmission hole is larger than the size of the transmission column, so that when the first connecting rod turntable is driven to rotate by the right connecting rod assembly, the first connecting rod turntable will not drive the rear connecting rod to move, but when the rear connecting rod is pushed, the first connecting rod turntable can be driven to rotate.

[0012] In some embodiments of this utility model, the front rotating arm, the rear rotating arm, the front bracket, and the rear bracket are connected by connecting screws, and the connecting screws are used as the hinge shafts between the front rotating arm and the front bracket, and between the rear rotating arm and the rear bracket.

[0013] In some embodiments of this utility model, a right-side opening spring is provided at the hinge position between the front rotating arm, the rear rotating arm and the front bracket, and the rear bracket; At the other end of the front rotating arm and the rear rotating arm, a hinge bracket is provided on the handrail body, and a left-side opening spring is provided between the front rotating arm, the rear rotating arm and the hinge bracket.

[0014] On the other hand, this utility model also provides an automotive armrest box, including the aforementioned interlocking, flip-open armrests on both sides.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention, through the design of linkage mechanisms and interlocking mechanisms, utilizes the coordinated actions between these mechanisms to achieve interlocking and linkage during the opening and closing of the handrail, preventing the handrail from popping out due to simultaneous button presses; once the button is pressed to open, it does not need to be pressed continuously, improving the user experience of opening the handrail and making the operation more convenient; after the handrail is opened, the linkage mechanism can be locked to prevent accidental operation; and the handrail assembly is easy to disassemble, facilitating handrail maintenance.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] This utility model aims to solve the problems of the current mainstream double-flip handrails, which are inconvenient for rear passengers to open, have a complex overall structure, have a poor user experience when opening, are prone to popping out and injuring people due to misoperation, and are difficult to disassemble and maintain after failure.

[0032] By designing linkage mechanisms and interlocking mechanisms, and utilizing the coordinated actions between these mechanisms, the handrails achieve interlocking and linkage during opening and closing, preventing them from popping out. Once the button is pressed to open, it is no longer necessary to hold it down, improving the user experience and making the handrail opening operation more convenient. The linkage mechanism can be locked after the handrail is opened to prevent accidental operation. Furthermore, the handrail assembly is easy to disassemble, facilitating handrail maintenance.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments of this utility model, the interlocking, flip-open armrests include: The base assembly 2 includes a base 20, a front bracket 21, and a rear bracket 22. The base assembly is connected to the car armrest storage box and is used to support the armrest. The front bracket and the rear bracket are respectively installed at the front and rear ends of the base by fixing screws. It should be noted that the front and rear in this utility model are based on the actual arrangement direction of the armrest box in the car. The end facing the front of the car is the front, and the end facing the rear of the car is the rear. Similarly, the side closer to the driver is the left, and the side closer to the passenger seat is the right.

[0034] The handrail assembly 1 includes the handrail body 10, a linkage mechanism, a reset mechanism, an opening mechanism, and an interlocking mechanism.

[0035] The linkage mechanism includes a left push plate 111, a right push plate 112, a left linkage assembly, a right linkage assembly, a rear linkage 115, and a first linkage turntable 116. The left push plate 111, the right push plate 112, the left linkage assembly, the right linkage assembly, and the rear linkage 115 are slidably engaged with the handrail body 10. The left push plate 111 and the right push plate 112 are arranged laterally along the handrail body 10, and the rear linkage 115 is arranged longitudinally along the handrail with one end extending to the rear end of the handrail body.

[0036] Reference Figure 5 The left and right linkage assemblies are respectively located on the left and right sides of the handrail body, each including a first link 113 and a second link 114. The first link 113 and the second link 114 are both arranged along the length of the handrail body and slide in cooperation with the handrail body. The first link and the second link are connected by a second link turntable 117. The second link turntable 117 is rotatably connected to the handrail body 10, and the second link turntable is hinged to the first link and the second link at both ends, so that the first link and the second link are linked. For example, when the first link moves towards the rear end of the handrail body (i.e., the unlocking direction), the second link can be driven to move towards the front end of the handrail body (i.e., the unlocking direction) under the action of the second link turntable, realizing the unlocking action of the left and right linkage assemblies; the locking process of the left and right linkage assemblies is also based on the same action principle.

[0037] The opening mechanism includes a front rotating arm 121 and a rear rotating arm 122, which are hinged to the front support 21 and the rear support 22 respectively on the same side of the handrail body. Figure 4 As shown, the front rotating arm 121 and the rear rotating arm 122 are respectively hinged to the front support 21 and the rear support 22 on the right side of the handrail body.

[0038] In the locked state, the left linkage assembly has its two ends inserted into the front and rear rotating arms, as well as the front and rear supports, respectively. For example, the front end of the first link of the left linkage assembly can be inserted into the front rotating arm and the front support in sequence, and the rear end of the second link can be inserted into the rear rotating arm and the rear support in sequence. The right linkage assembly has its two ends inserted into the front and rear rotating arms, respectively. That is, the front end of the first link of the right linkage assembly can be inserted into the front rotating arm, and the rear end of the second link can be inserted into the rear rotating arm. The left push plate and the left linkage assembly are connected by a transmission mechanism, and the right push plate and the right linkage assembly are connected by a transmission mechanism. When the left and right push plates are pushed, the connection between the left linkage assembly and the front and rear supports or the connection between the right linkage assembly and the front and rear rotating arms can be released, allowing the armrest assembly to be flipped open to one side.

[0039] The ends of the left push plate 111, the right push plate 112 and the rear push rod 115 are respectively provided with buttons 118 that are easy to press, and the buttons 118 are slidably connected to the handrail body 10.

[0040] The left push plate 111 and the right push plate 112 are arranged along the width direction of the handrail body and are arranged opposite to each other on the handrail body, respectively on the left and right sides of the handrail body.

[0041] When the button on the left push plate is pressed, the left push plate drives the first link of the left linkage assembly to move in the unlocking direction. Under the action of the first and second link turntables, the second link of the left linkage assembly simultaneously moves in the unlocking direction, causing the ends of the first and second links of the left linkage assembly to be pulled out from the front and rear brackets, respectively. At this time, the armrest assembly can rotate along the hinge axis between the front and rear rotating arms and the base assembly, allowing the armrest assembly to be opened from the left side. Figure 2 As shown.

[0042] When the button on the right push plate is pressed, the right push plate similarly drives the first link of the right linkage assembly to move in the unlocking direction, while the second link moves in the unlocking direction simultaneously. This causes the ends of the first and second links of the right linkage assembly to be pulled out from the front and rear rotating arms, respectively. At this time, the armrest assembly can rotate along the hinge axis formed by the connection between the left linkage assembly and the base assembly, allowing the armrest assembly to be opened from the right side. Figure 2 As shown.

[0043] The first linkage turntable 116 is rotatably connected to the armrest body 10, and the first linkage turntable is hinged to the right linkage assembly and the rear linkage at both ends respectively, so that when the rear linkage moves, it can drive the right linkage assembly to move to the unlocked state through the first linkage turntable.

[0044] When the button on the rear link is pressed, the rear link slides towards the front end of the armrest body. The rear link pushes the first link turntable to rotate, and the first link turntable drives the first link of the right link assembly to move in the unlocking direction, thereby unlocking the right link assembly. At this time, passengers in the rear seat can open the armrest assembly from the right side.

[0045] The reset mechanism provides the force to return the left and right linkage assemblies from the unlocked state to the locked state; such as Figure 5 The reset mechanism includes a reset spring 131 connected to a first link and a second link of the left link assembly and the right link assembly, respectively. The reset spring 131 is a torsion spring, which quickly returns the left link assembly and the right link assembly from the unlocked state to the initial locked state.

[0046] The interlocking mechanism includes a first limiting member 141 that is connected to the left link assembly. When one of the left link assembly or the right link assembly is unlocked, the first limiting member 141 and the first link turntable 116 can form an abutment engagement to prevent the other of the left link assembly or the right link assembly from being unlocked.

[0047] By setting up an interlocking mechanism, the cooperation between the first limiting member and the first linkage turntable creates a connection between the left linkage assembly, the right linkage assembly, and the rear linkage, preventing the buttons on the left linkage assembly, the right linkage assembly, and the rear linkage from being pressed simultaneously. This avoids the problem of the armrest assembly separating from the base assembly and the armrest assembly popping out and injuring people. Furthermore, when one side is unlocked, the other side cannot be unlocked.

[0048] In some embodiments, the first limiting member 141 is slidably engaged with the armrest body 10, so that the first limiting member 141 can move in a direction away from or towards the first link turntable, and the first limiting member 141 is in a transmission engagement with the left link assembly. When the left linkage assembly is unlocked, the left linkage assembly can drive the first limiting member to move toward the first connecting turntable and abut against the first connecting turntable to restrict the rotation of the first connecting turntable; when the right linkage assembly is unlocked, the first connecting turntable rotates to abut against the first limiting member to restrict the movement of the first limiting member.

[0049] like Figure 5 When the button on the left push plate is pressed, the first link of the left linkage assembly moves in the unlocking direction. At this time, the first link pushes the first limiting member, which is set along the width direction of the armrest body, to slide to the right and extend into the notch set at the end of the first linkage turntable, forming an abutment fit with the first linkage turntable and restricting the rotation of the first linkage turntable. At this time, the right linkage assembly and the rear link cannot be pushed. Similarly, when the right linkage assembly or the rear link is pushed to the unlock position, the first linkage turntable rotates to abut against the end of the first limiting member. At this time, the left linkage assembly cannot be pushed.

[0050] In some embodiments, the interlocking mechanism includes an interlocking bracket 142 and an interlocking spring 143. The interlocking bracket 142 is provided with a trigger part 1421 and an interlocking part 1422 opposite to each other. The interlocking bracket 142 is disposed on the handrail body near the front bracket and is rotatably connected to the handrail body 10. The interlocking spring 143 provides a force for the interlocking bracket to rotate, and the trigger part is limited to the front rotating arm to restrict the rotation of the interlocking bracket. When the armrest assembly is in the open position, the interlocking part rotates to a position that can restrict the movement of the left push plate, right push plate and rear linkage under the action of the interlocking spring and the front rotating arm. When the armrest assembly is in the closed state, the triggering part interacts with the front bracket, allowing the interlocking part to rotate to a position that releases the movement restrictions on the left push plate, right push plate, and rear linkage.

[0051] At this time, thanks to the interlocking bracket, no button can be pressed when the armrest assembly is fully open, ensuring the safety of the armrest assembly. For example... Figure 7 As shown, the trigger part has a "7" shaped structure, which forms a limiting fit between the horizontal section and the front rotating arm. The interlock bracket can be kept in this position through the fit between the two. The protruding section of the trigger part is used to form a trigger fit with the front bracket. During the closing process of the armrest assembly, when the protruding part contacts the front bracket, it triggers the interlock bracket to rotate, causing the interlock part to rotate downward, thereby releasing the movement restriction on the left push plate, right push plate and rear linkage.

[0052] In some embodiments, one end of the left push plate, the rear connecting rod, and the right push plate is arranged around the interlocking part, so that when the interlocking part rotates, it can enter the space enclosed by the ends of the left push plate, the rear connecting rod, and the right push plate and abut against the ends of the left push plate, the right push plate, and the rear connecting rod, or exit from the space enclosed by the ends of the left push plate, the rear connecting rod, and the right push plate. Here, "abutting" does not mean that the end faces of the two parts must be in contact, but rather that they form a state that allows for a limiting fit. For example, in this state, there can be a certain gap between the interlocking part and the ends of the left push plate, the right push plate, and the rear connecting rod, but this gap is insufficient to unlock the left and right connecting rod assemblies.

[0053] like Figure 6 The interlocking part 1422 is a square structure that matches the space enclosed by the ends of the left push plate, the rear connecting rod and the right push plate, so as to form a good fit with the ends of the left push plate, the rear connecting rod and the right push plate.

[0054] In some embodiments, the interlocking mechanism includes a locking component disposed on the interlocking bracket; When the armrest assembly is closed, the locking component can lock the left push plate, right push plate, or rear link in the unlocked position when the left push plate, right push plate, or rear link is pushed, keeping the left link assembly and right link assembly in the unlocked state; and when the armrest assembly is opened, the locking component rotates with the interlock bracket and releases the movement restriction on the left push plate, right push plate, or rear link.

[0055] In some embodiments, the locking assembly includes a left locking member 144, a right locking member 145, and a rear locking member 146 for locking the left push plate, the right push plate, and the rear connecting rod, respectively. The left locking member 144, the right locking member 145, and the rear locking member 146 are rotatably connected at one end to the interlock bracket 142. The left locking member 144, the right locking member 145, and the rear locking member 146 are respectively provided with a spring 147 between them and the interlock bracket 142, which can rotate them toward the side where the interlocking part is located.

[0056] By designing the locking components, when the left push plate is pushed in the unlocking direction, the left locking piece is lifted by the action of the spring and falls into the locking groove on the left locking piece, keeping the left linkage assembly in the unlocked state. This eliminates the need to hold down the button when unlocking, improving the user experience of opening the armrest. Similarly, when the rear linkage is pushed in the unlocking direction, the clip at the end of the rear locking piece falls into the locking groove at the end of the rear linkage, keeping the rear linkage in the unlocked state.

[0057] In some embodiments, the reset mechanism further includes a reset spring 131 that provides the left push plate and the right push plate with a return from the unlocked position to the initial position. The reset spring 131 is a torsion spring, which allows the left push plate, the right push plate, and the rear link to quickly return to their initial positions when the locking assembly releases the lock on the left push plate, the right push plate, and the rear link, providing space for the rotation of the interlocking part and preventing interference between the interlocking bracket and the left push plate, the right push plate, and the rear link when the interlocking bracket rotates to the limit position.

[0058] In some embodiments, a transmission post 1151 is provided on the rear link 115, and a transmission hole 1161 is provided at one end of the first link turntable 116. The transmission post 1151 extends into the transmission hole 1161, and the size of the transmission hole is larger than the size of the transmission post, so that when the first link turntable is driven to rotate by the right link assembly, the first link turntable will not drive the rear link to move, but when the rear link is pushed, the first link turntable can be driven to rotate.

[0059] In some embodiments, the front rotating arm 121, the rear rotating arm 122 are connected to the front bracket 21 and the rear bracket 22 by connecting screws 151, and the connecting screws are used as the hinge axes between the front rotating arm and the front bracket, and between the rear rotating arm and the rear bracket.

[0060] The existing side-opening armrests require the entire base assembly and armrest assembly to be removed before repairs can be performed. In some cases, when the interior space is too small to directly remove the base, the center console also needs to be removed, which makes armrest repairs very difficult.

[0061] like Figure 8 As shown, taking the hinged connection between the front rotating arm and the front bracket as an example, the connecting screw 151 passes through the front rotating arm 121 and is threadedly connected to the front bracket 21. The connecting screw 151 abuts against the front rotating arm 121 at the other end, so that the connecting screw can serve as the rotation axis of the two while connecting the front rotating arm and the front bracket. When the armrest assembly is opened and closed from the left side, it can rotate around the connecting screw.

[0062] The use of connecting screws facilitates the disassembly of the handrail assembly, making it easier to perform maintenance. The following section will discuss this further. Figure 3 Taking the armrest assembly opening to the right as an example, the disassembly process of the armrest assembly in this embodiment will be explained. In the open state, the trigger part is lifted, causing the interlock part to release the restriction on the left push plate, right push plate, and rear linkage. At this time, since the left linkage assembly on the left side has been unlocked from the base assembly, it is only necessary to press the button on the right side or the rear side to unlock the right linkage assembly. Then, lift the armrest assembly upwards, so that both sides of the armrest assembly are separated from the base assembly. Figure 12 As shown, finally remove the connecting screws to detach the armrest assembly from the base assembly.

[0063] Similarly, with the armrest assembly opened to the left, the armrest assembly can be easily disassembled using the above disassembly method.

[0064] In some embodiments, a right-side opening spring 154 is provided at the hinge position between the front rotating arm 121, the rear rotating arm 122 and the front bracket 21, the rear bracket 22; a hinge bracket 156 is provided on the armrest body 10 at the other end of the front rotating arm and the rear rotating arm, and a left-side opening spring 155 is provided between the front rotating arm 121, the rear rotating arm 122 and the hinge bracket. The left-side opening spring and the right-side opening spring provide auxiliary forces for opening the armrest assembly and keep the armrest assembly in a suspended state, such as... Figure 10 and Figure 11 As shown.

[0065] The hinge bracket is fixedly connected to the handrail body, and the front and rear rotating arms are connected to the hinge bracket on this side via a second hinge shaft 152. Figure 9As shown, taking the connection structure of the front rotating arm as an example, the second hinge shaft 152 passes through the front rotating arm and the hinge bracket, and abuts against the front rotating arm at one end, and abuts against the hinge bracket at the other end through the retaining ring 153, thereby realizing the installation of the second hinge shaft. When the handrail assembly is opened and closed from the left side, it rotates around the second hinge shaft. When the handrail assembly is disassembled, the handrail assembly can be disassembled simply by removing the retaining ring.

[0066] When the handrail assembly is opened, the left and right opening springs open it to the hovering angle. When the handrail assembly is closed, if the lock is not fully engaged (a false lock occurs), the trigger of the interlock bracket will not be able to drive the interlock to the unlock position. At this time, the interlock will always restrict the movement of the left push plate, right push plate and rear linkage, preventing the handrail assembly from being opened and ensuring safety during handrail operation.

[0067] On the other hand, in some embodiments of this utility model, it is a car armrest box, including a storage box and the armrest in the above embodiments.

[0068] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.

The first limiting member is in a transmission engagement with the left connecting rod assembly. When the left linkage assembly is unlocked, the left linkage assembly can drive the first limiting member to move toward the first connecting turntable and abut against the first connecting turntable to restrict the rotation of the first connecting turntable; when the right linkage assembly is unlocked, the first connecting turntable rotates to abut against the first limiting member to restrict the movement of the first limiting member.

3. The interlocking, two-sided flip-open handrail according to claim 1, characterized in that, The interlocking mechanism includes an interlocking bracket and an interlocking spring. The interlocking bracket has a triggering part and an interlocking part arranged opposite to each other. The interlocking bracket is set on the handrail body near the front bracket and is rotatably connected to the handrail body. The interlocking spring provides a force to the interlocking bracket to rotate it, and the triggering part is limited to the front rotating arm to restrict the rotation of the interlocking bracket. When the armrest assembly is in the open position, the interlocking part rotates to a position that can restrict the movement of the left push plate, right push plate and rear linkage under the action of the interlocking spring and the front rotating arm. When the armrest assembly is in the closed state, the triggering part interacts with the front bracket, allowing the interlocking part to rotate to a position that releases the movement restrictions on the left push plate, right push plate, and rear linkage.

4. The interlocking, two-sided flip-open handrail according to claim 3, characterized in that, The left push plate, the rear connecting rod, and one end of the right push plate are arranged around the interlocking part, so that when the interlocking part rotates, it can enter the space enclosed by the ends of the left push plate, the rear connecting rod, and the right push plate and abut against the ends of the left push plate, the right push plate, and the rear connecting rod, or exit from the space enclosed by the ends of the left push plate, the rear connecting rod, and the right push plate.

5. The interlocking, two-sided flip-open handrail according to claim 3, characterized in that, The interlocking mechanism includes a locking component mounted on the interlocking bracket; When the handrail assembly is closed, the locking component can lock the left push plate, right push plate, or rear link in the unlocked position when the left push plate, right push plate, or rear link is pushed, keeping the left link assembly and right link assembly in the unlocked state; and when the handrail assembly is opened, the locking component rotates with the interlock bracket and releases the movement restriction on the left push plate, right push plate, or rear link.
