DETAILED DESCRIPTION
[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0053] This application provides a split armrest, please refer to Figures 1 to 3 , Figure 1 This is a schematic structural diagram of the split armrest disclosed herein. Figure 2 yes Figure 1 The schematic diagram of the structure in which the drive shaft is connected to the transmission assembly is shown. Figure 3 yes Figure 2 The split armrest 10 comprises a base 1 , two armrest bodies 2 , two transmission assemblies and a drive shaft 41 .
[0054] The two armrest bodies 2 are rotatably mounted on the base 1 , and the two armrest bodies 2 have an open position away from each other and a closed position close to each other.
[0055] It should be noted that the method for rotatably mounting the armrest body 2 to the base 1 can be selected as needed. For example, in one embodiment, the armrest body 2 can be rotatably mounted to the base 1 via a rotation axis. In other embodiments, the armrest body 2 can also be rotatably mounted to the base 1 via a hinge 8. Specifically, this application does not limit the method for rotatably mounting the armrest body 2 to the base 1.
[0056] Each transmission assembly includes a first bevel gear 31 and a second bevel gear 32 . The two second bevel gears 32 are respectively connected to the two armrest bodies 2 . The first bevel gear 31 and the second bevel gear 32 are meshed with each other.
[0057] It should be noted that the method of connecting the second bevel gear 32 to the armrest body 2 can be selected as needed. For example, in one embodiment, the second bevel gear 32 and the armrest body 2 can be fixed together by a clamping structure. In another embodiment, the second bevel gear 32 and the armrest body 2 can be fixed together by gluing. Specifically, this application does not limit the method of connecting the second bevel gear 32 and the armrest body 2.
[0058] The drive shaft 41 is rotatably mounted on the base 1 and is connected to the two first bevel gears 31. The power of the drive shaft 41 is transmitted to the two armrest bodies 2 through the two first bevel gears 31 and the two second bevel gears 32, so that the two armrest bodies 2 rotate and switch between the open position and the closed position.
[0059] It should be noted that the axis of each first bevel gear 31 is coaxially arranged with the drive shaft 41. Furthermore, the method of connecting the drive shaft 41 to the first bevel gear 31 can be selected as needed. For example, in one embodiment, the drive shaft 41 and the first bevel gear 31 can be connected by a key. In another embodiment, the drive shaft 41 and the first bevel gear 31 can also have an interference fit. In other embodiments, the drive shaft 41 and the first bevel gear 31 can also be connected by a pin. Specifically, this application does not limit the method of connecting the drive shaft 41 to the first bevel gear 31.
[0060] In the technical solution of the present application, since the drive shaft 41 is connected to the two first bevel gears 31, the two second bevel gears 32 are respectively connected to the two armrest bodies 2, and the two first bevel gears 31 and the two second bevel gears 32 are meshed, when the drive shaft 41 is driven to rotate, the drive shaft 41 drives the two connected first bevel gears 31 to rotate, the two first bevel gears 31 drive the two meshed second bevel gears 32 to rotate, and the rotation of the two second bevel gears 32 drives the two connected armrest bodies 2 to rotate synchronously, thereby switching the two armrest bodies 2 between the open position and the closed position. One drive shaft 41 drives the two armrest bodies 2 through the two first bevel gears 31 and the two second bevel gears 32, which has a simple structure and low cost.
[0061] In addition, since the first bevel gear 31 and the second bevel gear 32 are meshed, the axes of the first bevel gear 31 and the second bevel gear 32 are arranged perpendicular to each other. This design makes the transmission assembly compact and reduces the space required for installation.
[0062] In some embodiments, the transmission ratio of the second bevel gear 32 to the first bevel gear 31 is i, where 2.5≤i≤5. This allows the second bevel gear 32 to rotate a larger angle while the first bevel gear 31 rotates a smaller angle, simplifying and reducing effort in switching the armrest body 2 between the open and closed positions. Because the first bevel gear 31 requires a smaller rotation angle, the operating space required to drive the drive shaft 41 is reduced, allowing the drive shaft 41 to rotate even within a smaller operating space.
[0063] It should be noted that the transmission ratio between the second bevel gear 32 and the first bevel gear 31 can be selected as needed. For example, the transmission ratio between the first bevel gear 31 and the second bevel gear 32 can be 2.5, 3, 3.5, 4, 4.5, or 5. Specifically, this application does not impose any restrictions on the transmission ratio between the first bevel gear 31 and the second bevel gear 32. Specifically, in one embodiment, the transmission ratio between the second bevel gear 32 and the first bevel gear 31 is 3. A 30° rotation of the first bevel gear 31 results in a 90° rotation of the second bevel gear 32. Furthermore, the first gear rotation angle range can be 65° to 110°.
[0064] Combine Figure 4 , Figure 4 yes Figure 2 Schematic diagram of the structure showing the locking portion in the unlocked position. In some embodiments, the drive shaft 41 is suitable for rotating around its axis between a first position and a second position. When the drive shaft 41 is in the first position, the two armrest bodies 2 are in the open position. When the drive shaft 41 is in the second position, the two armrest bodies 2 are in the closed position. In this way, by rotating the drive shaft 41 between the first position and the second position, the two armrest bodies 2 can be accurately controlled to be in the open position or the closed position. The split armrest 10 also includes a first elastic portion 42, which is elastically connected between the drive shaft 41 and the base 1. The first elastic portion 42 is suitable for driving the drive shaft 41 to rotate to the first position. In this way, this design realizes that when there is no other external force or specific operation to cause the drive shaft 41 to deviate from the first position, the first elastic portion 42 can maintain the drive shaft 41 in the first position by its own elastic force, so that the armrest body 2 automatically returns to the open position, increasing the convenience of use. The use of the first elastic portion 42 to achieve the automatic reset and partial drive functions of the drive shaft 41 simplifies the structure of the entire split armrest 10 to a certain extent. Compared with the use of complex motor drive or multiple gear transmission solutions, the number and type of parts are reduced, and the manufacturing cost of the split armrest 10 is reduced. At the same time, the simple structure also makes the assembly and maintenance of the split armrest 10 easier, reducing the assembly difficulty during the production process and the workload during later maintenance, and improving production efficiency and product maintainability. The first elastic portion 42 is elastically connected between the drive shaft 41 and the base 1. This design requires relatively little space.
[0065] Reference Figure 2 and Figure 5 , Figure 5 It is a schematic diagram of the structure in which the drive shaft, the matching part, the drive part and the first elastic part of the present invention are connected. In some embodiments, the first elastic part 42 includes a torsion spring, which is sleeved on the drive shaft 41, one end of the torsion spring is connected to the drive shaft 41, and the other end of the torsion spring is connected to the base 1. In this way, the torsion spring is sleeved on the drive shaft 41. This design makes full use of the space around the drive shaft 41, making the structure of the entire split armrest 10 more compact. One end of the torsion spring is connected to the drive shaft 41, and the other end is connected to the base 1. This connection method can ensure that the torsion spring always maintains an effective connection with the two during the rotation of the drive shaft 41, and will not fall off or loosen easily. When the drive shaft 41 rotates to twist the torsion spring, the torsion spring will generate a restoring force opposite to the direction of rotation. This restoring force can drive the drive shaft 41 back to the first position, thereby causing the armrest body 2 to move to the open position.
[0066] It should be noted that, in other embodiments, the first elastic portion 42 may also include a spring or an elastic band, etc. Specifically, the present application does not limit the type of the first elastic portion 42.
[0067] Reference Figures 2 to 4 In some embodiments, the drive assembly further includes a drive arm 43 and an operating portion 44. The drive arm 43 is connected to the drive shaft 41. The operating portion 44 is movably mounted on the base 1 and is movable between a first initial position and a first downward-pressing position. When the operating portion 44 moves from the first initial position to the first downward-pressing position, the operating portion 44 is adapted to drive the drive shaft 41 to rotate to a second position via the drive arm 43. In this way, the operating portion 44 is movable between the first initial position and the first downward-pressing position. This design enables the user to trigger the rotation of the drive shaft 41 with a simple downward-pressing action. The drive arm 43 is equivalent to a lever. According to the principle of leverage, a relatively small downward force can be used to generate a relatively large rotational torque, thereby driving the drive shaft 41 to rotate. This makes operation simple and labor-saving.
[0068] In addition, the operating portion 44 moves between the first initial position and the first downward position, and can accurately drive the drive shaft 41 to rotate to the second position. This precise position correspondence ensures that the drive shaft 41 can work in a predetermined manner, thereby achieving precise control of the split armrests 10. When the operating portion 44 moves from the first initial position to the first downward position, it can reliably drive the drive shaft 41 to rotate to the second position, thereby achieving the movement of the two armrests to the closed position. This design uses a combination of a drive arm 43 and an operating portion 44 to achieve the rotation of the drive shaft 41. Compared with some complex transmission mechanisms, such as gear transmission, chain transmission, etc., the structure is simpler. The simple structure reduces the number and types of parts, reduces the difficulty of manufacturing and assembly, and also reduces the possibility of failure of the split armrests 10 due to wear or failure of parts.
[0069] Reference Figure 2 In some embodiments, when the drive shaft 41 is in the first position, the drive arm 43 abuts against the operating portion 44 in the first initial position. In this way, this abutment design provides a clear mechanical positioning point for the drive shaft 41. When the drive shaft 41 reaches the first position, the drive arm 43 abuts against the operating portion 44, just like setting a "terminal station" for the movement of the drive shaft 41, which enables the drive shaft 41 to stop accurately at a predetermined position, so that the armrest body 2 driven by the drive shaft 41 can also be accurately in the open position. The abutment between the drive arm 43 and the operating portion 44 can fix the position of the drive shaft 41 and prevent the drive shaft 41 from unnecessary displacement under the action of external force, thereby ensuring the stability and reliability of the entire double-sided armrest 10 structure.
[0070] In addition, if there is no abutment restriction between the drive arm 43 and the operating part 44, the drive shaft 41 may continue to rotate under the action of external force or inertia, and transmit the power of the drive shaft 41 to the armrest body 2 through the transmission assembly, causing the armrest body 2 to continue to move and collide with other parts, be squeezed, and other damages.
[0071] In some embodiments, the drive assembly further includes a second elastic portion 45, which elastically connects the operating portion 44 to the base 1 and is adapted to maintain the operating portion 44 in the first initial position. This second elastic portion 45 automatically returns the operating portion 44 to the first initial position when no external force is applied, providing the user with clear operational feedback. When the user completes the downward pressure operation, the operating portion 44 is visually reset, clearly indicating that the operation has ended and that the operating portion 44 has returned to the first initial position. The provision of the second elastic portion 45 enables the operating portion 44 to quickly and accurately return to the first initial position, allowing the user to quickly proceed with the next operation, thereby improving operational continuity and efficiency. The operating portion 44 remains in the first initial position under the action of the second elastic portion 45, reducing the risk of movement of the two armrest bodies 2 due to accidental movement of the operating portion 44. The operating portion 44 will only move, and thus the drive arm 43, when the user actively applies downward pressure that exceeds the elastic force of the second elastic portion 45.
[0072] In addition, the second elastic portion 45 ensures that the operating portion 44 always remains in the first initial position, providing a stable condition for the abutment between the driving arm 43 and the operating portion 44. When the driving shaft 41 is in the first position, the driving arm 43 can accurately abut the operating portion 44 in the first initial position, thereby accurately limiting the further rotation of the driving shaft 41.
[0073] Reference Figures 2 to 4 In some embodiments, the split armrest 10 further includes a locking assembly, which includes a mating portion 51 and a locking portion 52. The mating portion 51 is provided on the drive shaft 41, and the locking portion 52 is movably mounted on the base 1 and can move between a locked position and an unlocked position. When the locking portion 52 is in the locked position, the locking portion 52 is adapted to lock and cooperate with the mating portion 51, so that the drive shaft 41 remains in the second position. When the locking portion 52 is in the unlocked position, the locking portion 52 is adapted to unlock with the mating portion 51, so that the drive shaft 41 is adapted to be driven to rotate to the first position by the first elastic portion 42. In this way, the user can easily lock and release the state of the drive shaft 41 by simply controlling the locking portion 52 to move between the locked position and the unlocked position, which is simple to operate. When the user needs to use the armrest body 2 to move to the open position, he only needs to place the locking part 52 in the unlocked position, and the drive shaft 41 rotates to the first position under the action of the first elastic part 42, and the corresponding two armrest bodies 2 move to the open position. After use, drive the drive shaft 41 to rotate to the second position, and then place the locking part 52 in the locked position to keep the drive shaft 41 in the second position, so that the armrest body 2 can be fixed in the closed position. This can effectively prevent the two armrest bodies 2 from accidentally moving to the open position due to external force.
[0074] Reference Figures 2 to 4In some embodiments, the locking portion 52 includes a locking surface 521, and the mating portion 51 includes an abutting arm 511. The abutting arm 511 is connected to the drive shaft 41. When the drive shaft 41 is in the second position, the abutting arm 511 abuts the locking surface 521, and the direction of the force exerted by the locking surface 521 on the abutting arm 511 is opposite to the direction of the elastic force exerted by the first elastic portion 42 on the drive shaft 41. Thus, the direction of the force exerted by the locking surface 521 on the abutting arm 511 and the elastic force exerted by the first elastic portion 42 on the drive shaft 41 form a mutually constrained force system, which can effectively prevent the drive shaft 41 from rotating under the action of the first elastic portion 42, thereby ensuring that the two armrest bodies 2 are reliably maintained in the closed position. In actual use, the split armrest 10 may be subject to various external interference forces. The opposing force between the locking surface 521 and the abutting arm 511 can enhance the locking assembly's ability to resist these external interference forces, keeping the two armrest bodies 2 stably in the closed position.
[0075] In some embodiments, the abutting arm 511 has a first abutting surface 5111 that abuts the locking surface 521. The first abutting surface 5111 is at least partially configured as a first arcuate curved surface 51111, which is convex toward the locking surface 521. The provision of the first arcuate curved surface 51111 reduces the contact area between the first abutting surface 5111 and the locking surface 521, thereby reducing friction between the locking portion 52 and the abutting arm 511 and reducing wear on the locking portion 52 and the abutting arm 511. Furthermore, the first arcuate curved surface 51111 also serves as a guide, making it easier for the abutting arm 511 to engage or unlock with the locking surface 521.
[0076] In some embodiments, the locking portion 52 has a second abutting surface 522, which is connected to the locking surface 521. When the drive shaft 41 switches from the first position to the second position, the end of the abutting arm 511 away from the drive shaft 41 is suitable for abutting against the second abutting surface 522, thereby driving the locking portion 52 to move to the unlocking position, ensuring that the rotational motion of the drive shaft 41 can be efficiently converted into the linear motion of the locking portion 52, and the structure is simple.
[0077] Reference Figure 3 and Figure 4 In some embodiments, the end of the abutment arm 511 away from the drive shaft 41 is rounded. This rounded corner makes the end of the abutment arm 511 smooth and rounded, reducing sharp contact with the second abutment surface 522 and preventing the abutment arm 511 from scratching the second abutment surface 522 during movement. Furthermore, the rounded corner of the end of the abutment arm 511 away from the drive shaft 41 can serve as a guide, making the relative movement between the abutment arm 511 and the second abutment surface 522 smoother and reducing wear.
[0078] Reference Figure 6 , Figure 6 Schematic diagram of the structure of the locking portion of the present disclosure. In some embodiments, the second abutting surface 522 is at least partially configured as a second arcuate surface 5221. The second arcuate surface 5221 is recessed in the direction away from the drive shaft 41 along the movable direction of the locking portion 52. The second arcuate surface 5221 is adapted to abut against the end of the abutting arm 511 away from the drive shaft 41. Thus, when the end of the abutting arm 511 away from the drive shaft 41 abuts against the second arcuate surface 5221, the force exerted by the end of the abutting arm 511 away from the drive shaft 41 on the second arcuate surface 5221 has a component in the direction from the locked position to the unlocked position, and this component can drive the locking portion 52 to the unlocked position. Furthermore, the second arcuate surface 5221 also serves as a guide. During the locking process, when the abutting arm 511 approaches the locking portion 52, the second arcuate surface 5221 guides the abutting arm 511 to gradually move along the contour of the curved surface, accurately reaching the locked position and achieving a tight fit with the locking portion 52. Furthermore, this guiding effect prevents the abutting arm 511 from deflecting or becoming stuck during the locking process, thereby improving the accuracy and reliability of the locking.
[0079] Reference Figure 2 and Figure 3 In some embodiments, the split armrest 10 further includes a drive unit 6, which is movably mounted on the base 1 between a second initial position and a second depressed position. The locking portion 52 includes a driving bevel 523 disposed toward the drive unit 6. The driving bevel 523 is disposed away from the drive unit 6 along the direction from the unlocked position to the locked position. When the drive unit 6 moves from the second initial position to the second depressed position, the drive unit 6 drives the locking portion 52 to move from the locked position to the unlocked position. Thus, this design ensures that when the drive unit 6 moves from the second initial position to the second depressed position, the driving force applied by the drive unit 6 to the driving bevel 523 has a force component along the direction from the locked position to the unlocked position. This force component enables the locking portion 52 to move from the locked position to the unlocked position, preparing for the subsequent locking engagement of the locking portion 52 with the mating portion 51. The movement of the locking portion 52 is achieved through mechanical contact and interaction between the drive unit 6 and the driving bevel 523. This mechanical linkage method has high reliability. Compared with electronic control or other complex methods, the mechanical structure is not easily affected by external environmental factors under normal working conditions, and can stably realize the driving function of the driving part 6 on the locking part 52 according to the design requirements, ensuring that the locking part 52 can accurately move from the locking position to the unlocking position, thereby ensuring the normal operation of the entire double-leaf armrest 10.
[0080] Reference Figure 7 , Figure 7: is a schematic diagram of the structure in which the operating part and the driving part of the present invention are connected. In some embodiments, the driving part 6 is connected to the operating part 44. In this way, when the operating part 44 is driven to move from the first initial position to the first downward pressing position, the driving part 6 moves from the second initial position to the second downward pressing position, so that the user only needs to apply a force to one of the operating part 44 or the driving part 6 to drive the other part to move at the same time. For example, when the user presses down on the operating part 44 to move it from the first initial position to the first downward pressing position, not only does the operating part 44 itself complete the position change, but it also drives the driving shaft 41 to rotate to the second position through the driving arm 43; at the same time, the operating part 44 drives the driving part 6 to move from the second initial position to the second downward pressing position, so that the driving part 6 drives the locking part 52 to unlock. This design reduces the steps that the user needs to operate multiple components separately, simplifies the operation process, and improves the efficiency of the operation.
[0081] Furthermore, connecting the drive unit 6 and the operating unit 44 eliminates the need for separate mounting structures and connection assemblies for each component, making the overall structure of the split armrest 10 more compact and concise. Because the drive unit 6 and the operating unit 44 are connected, motion transmission between them is direct and precise, eliminating the problems of transmission errors, slippage, and looseness that can occur in traditional transmission mechanisms. When the operating unit 44 drives the drive shaft 41 to rotate, or when the drive unit 6 drives the locking unit 52 to move, synchronized motion is achieved in strict accordance with design requirements, ensuring that each component reaches its intended position, thereby ensuring accurate functioning of the device.
[0082] It should be noted that the method of connecting the driving portion 6 and the operating portion 44 can be selected as needed. For example, in one embodiment, the driving portion 6 and the operating portion 44 can be integrally formed. In another embodiment, the driving portion 6 and the operating portion 44 can also be fixed by screws, snap-fit structures, glue, etc. Specifically, this application is not limited to this.
[0083] Reference Figure 7In some embodiments, the driving portion 6 has a matching bevel 61 that mates with the driving bevel 523. Thus, because the matching bevel 61 mates with the driving bevel 523, the movement of the driving portion 6 can be transmitted to the locking portion 52 without delay, thereby improving the timeliness and accuracy of the movement of the driving locking portion 52. The design of the matching bevel 61 mates with the driving bevel 523 increases the contact area between the driving portion 6 and the locking portion 52, thereby reducing the risk of damage due to stress concentration between the driving portion 6 and the locking portion 52, and improving the driving reliability of the driving portion 6 and the locking portion 52. In addition, the fit between the matching bevel 61 and the driving bevel 523 can provide a precise guiding effect, making the relative movement between the driving portion 6 and the locking portion 52 more accurate. Since the contact area between the matching bevel 61 and the driving bevel 523 is large and the force distribution during movement is relatively uniform, stress concentration is avoided, thereby improving the service life of the driving portion 6 and the locking portion 52.
[0084] Reference Figure 3 and Figure 4 In some embodiments, the locking assembly further includes a third elastic portion 53, which elastically connects the locking portion 52 and the base 1, and is adapted to keep the locking portion 52 in the locked position. In this way, the third elastic portion 53 provides a continuous and stable elastic force for the locking portion 52, ensuring that the locking portion 52 is always firmly in the locked position in the absence of external force. Since the third elastic portion 53 stably maintains the locking portion 52 in the locked position, when unlocking, it is only necessary to apply an external force in the opposite direction of the elastic force to overcome the elastic force of the third elastic portion 53 so that the locking portion 52 can be moved from the locked position to the unlocked position. This design makes the unlocking operation simpler and more direct. The user only needs to apply a force to overcome the elastic force of the spring to move the locking portion 52 from the locked position, making the operation convenient and quick.
[0085] It should be noted that there are many types of the third elastic portion 53, for example, the third elastic portion 53 may include a spring, an elastic rope, a rubber block, etc. Specifically, this application does not limit this.
[0086] Reference Figure 2In some embodiments, the split armrest 10 further includes a damper 7, which is mounted on the drive shaft 41. The damper 7 is used to limit the rotation speed of the drive shaft 41, thereby avoiding sudden collisions and shaking caused by excessive rotation speed of the drive shaft 41, and improving the comfort of the split armrest 10. Excessive rotation speed of the drive shaft 41 will cause the drive shaft 41 and its related components to be subjected to greater impact force and stress, which may easily lead to damage such as wear and breakage of the components after long-term use. The presence of the damper 7 can reduce the load on the drive shaft 41, reduce the impact force it receives, and protect the structural safety of the entire split armrest 10. The rapidly rotating drive shaft 41 may also cause vibration of the entire split armrest 10 structure, thereby generating vibration noise. The damper 7 can absorb and consume part of the vibration energy, suppress the vibration of the structure, and thus reduce the generation of vibration noise.
[0087] It should be noted that the technology of the damper 7 is mature, and the principle of limiting the rotation speed of the drive shaft 41 by the damper 7 is not described in detail in this application.
[0088] The working principle of the split armrest 10 is described in detail below, wherein the transmission ratio of the first bevel gear 31 to the second bevel gear 32 is 3 and the operating part 44 and the driving part 6 are integrally provided as an example.
[0089] Initially, the armrest body 2 is in the closed position. By applying an external force to the drive unit 6, the drive unit 6 moves from the second initial position to the second downward position. During this process, the drive unit 6 drives the locking portion 52 to move from the locked position to the unlocked position. When the locking portion 52 is in the unlocked position, the locking portion 52 is unlocked from the mating portion 51, so that the drive shaft 41 is suitable for being driven by the first elastic portion 42 to rotate to the first position. When the drive shaft 41 rotates, the power of the drive shaft 41 is transmitted to the two armrest bodies 2 through the two first bevel gears 31 and the two second bevel gears 32, so that the two armrest bodies 2 rotate to the closed position. Due to the action of the armrest damper 7, the drive shaft 41 rotates slowly. Among them, when the drive shaft 41 rotates 30°, the second rotating gear rotates 90°, so that the drive shaft 41 rotates a small angle to make the two armrest bodies 2 rotate a larger angle to reach the open position. In addition, since the drive shaft 41 is in the first position, the drive arm 43 abuts against the operating part 44 in the first initial position, thereby limiting the continued rotation of the drive shaft 41 and ensuring that the two armrest bodies 2 will not continue to rotate after accurately reaching the 90° open position.
[0090] It should be noted that, when the two armrest bodies 2 are in the open position, the locking portion 52 is reset to the locking position under the action of the third elastic portion 53 .
[0091] When it is necessary to switch the two armrest bodies 2 from the open position to the closed position, it is only necessary to press the operating part 44 so that the operating part 44 switches from the first initial position to the first downward position. During this process, the operating part 44 drives the driving shaft 41 to rotate to the second position through the driving arm 43. During the rotation of the driving shaft 41, the matching part 51 connected thereto will be driven to rotate, and the abutting arm 511 of the matching part 51 pushes the locking part 52 from the locked position to the unlocked position. When the driving shaft 41 rotates to the second position, the corresponding two armrest bodies 2 move to the closed position, and the abutting arm 511 moves to be misaligned with the locking part 52, so that the force applied to the locking part 52 disappears, and the locking part 52 moves to the locked position under the action of the third elastic part 53. The locking part 52 is locked with the matching part 51, which limits the rotation of the driving shaft 41, so that the two armrest bodies 2 are restricted in the closed position, avoiding misoperation causing the armrest body 2 to switch to the open position.
