Abstract

The utility model provides a handrail mechanism and machine equipment. The handrail mechanism is installed on a machine body of the machine equipment and comprises a handrail assembly and a locking assembly. The handrail assembly comprises a first handrail set and a second handrail set, the first handrail set is rotationally installed on the machine body and provided with a storage position, and the second handrail set is installed on the first handrail set in a telescopic mode and provided with a contraction position. The locking assembly is movably installed on the first handrail set and provided with a locking position and a full-unlocking position. When the second armrest set extends out of the contraction position, the locking assembly can correspondingly move out of the locking position so as to release locking fit between the first armrest set and the machine body. When the second handrail set extends to the complete extending position, the locking assembly cannot automatically reset to the locking position, locking matching between the handrail assembly and the machine body is relieved and kept, and therefore it is guaranteed that when the handrail assembly is in the extending state, a labor-saving lever structure cannot be formed, and the machine body cannot be lifted; the reliability and the service life of machinery equipment are improved.

Description

Technical Field

[0001] The utility model relates to the field of cleaning technology, and particularly to an armrest mechanism and a machine device. Background Art

[0002] Most of the armrests of similar machines in the existing market are completely hidden and locked to the body of the machine. When the armrest is in the pulled-out state and the unlocking sliding sleeve of the armrest is buckled on the upper cover of the machine body, a long-arm lever structure is formed. At this time, it is easy for the user to lift the end of the armrest, and the whole machine takes the wheel axle or the front and rear edges of the machine as the fulcrum to lift the whole machine forward. In this state, the components at the bottom of the front side of the machine are easy to touch the ground to form a small-area lever structure and break the corresponding components. Content of the Utility Model

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0035] In one embodiment, a machine device is provided, comprising a machine body and an armrest mechanism, wherein the armrest mechanism is mounted on the machine body, so that a user can drive the machine body to move through the armrest mechanism, thereby improving the practicality of the machine device.

[0036] The armrest mechanism can be installed on the machine body by snap connection, screw connection or other connection methods.

[0037] It should be noted that the present application is described in detail by taking the armrest mechanism applied to a machine device as an example. In other embodiments, the armrest mechanism can also be applied to other similar products or devices.

[0038] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, an armrest mechanism 10 is provided, which includes a mounting base 100, an armrest assembly 200, and a first limiting assembly 300. Among them, the armrest assembly 200 is rotatably coupled to the mounting base 100. The first limiting assembly 300 includes a damping member 310 and a one-way rotating member 320 arranged along the rotation axis direction of the armrest assembly 200. The damping member 310 is connected to the one-way rotating member 320, and one of them is connected to the mounting base 100, and the other is connected to the armrest assembly 200. When the armrest assembly 200 rotates in the opening direction, the one-way rotating member 320 is in a rotating state, and the damping member 310 does not generate damping; when the armrest assembly 200 rotates in the pressing direction (i.e., the direction opposite to the opening direction), the one-way rotating member 320 is in a self-locking state, and the damping member 310 generates damping.

[0039] For the armrest mechanism 10 in the above embodiment, during use, the mounting base 100 is correspondingly mounted on the fuselage so that the armrest assembly 200 can rotate and open or rotate and press relative to the fuselage. Among them, when the user drives the armrest assembly 200 to rotate in the opening direction, the one-way rotating member 320 is in a rotating state, and the entire damping member 310 rotates synchronously with the armrest assembly 200 or remains fixed to the mounting base 100. At this time, the damping member 310 does not generate damping, and the resistance received by the armrest assembly 200 is tiny and can be easily opened. When the user releases the armrest assembly 200 and the armrest assembly 200 rotates in the pressing direction under its own gravity, the one-way rotating member 320 is in a self-locking state, and the entire one-way rotating member 320 remains fixed to the mounting base 100 or rotates synchronously with the armrest assembly 200. At this time, relative movement occurs on both sides of the damping member 310 and damping is generated, so that the armrest assembly 200 has the function of freely hovering, can adapt to the experience needs of users of different heights, and improves the practicability of the armrest mechanism 10. In addition, there is no mechanical structure limit during the entire rotation process of the armrest assembly 200. When the fuselage is subjected to resistance or impact force, the damping member 310 can provide a direction and space for relieving force, reducing the probability of structural damage to the armrest mechanism 10 and improving the safety and reliability of the armrest mechanism 10.

[0040] Among them, the armrest assembly 200 can be any armrest in the prior art. The damping member 310 can be set as a damper, a damping spring, or other damping structures. The one-way rotating member 320 can be set as a one-way bearing, a ratchet and pawl structure, or other one-way rotating structures.

[0041] Such as Figure 2As shown, further, the damping member 310 and the one-way rotating member 320 are arranged at intervals. The first limiting assembly 300 further includes an adapter 330 located between the damping member 310 and the one-way rotating member 320. The adapter 330 is connected to both the damping member 310 and the one-way rotating member 320. In this way, the damping member 310 can be connected to the one-way rotating member 320 as a whole through the adapter 330, so as to transmit the damping generated by the damping member 310 to the one-way rotating member 320 and improve the reliability of the armrest mechanism 10.

[0042] Among them, the adapter 330 can be set as an adapter seat, an adapter bracket or other adapter structures. The rotation axes of the armrest assembly 200, the damping member 310, the adapter 330, and the one-way rotating member 320 are all the same straight line. The adapter 330 can be connected to the damping member 310 by clamping, plugging, screwing or other means. The adapter 330 can be connected to the one-way rotating member 320 by clamping, plugging, screwing or other means. The damping member 310 can be connected to one of the armrest assembly 200 and the mounting seat 100 by clamping, plugging, screwing or other means. The one-way rotating member 320 can be connected to the other of the armrest assembly 200 and the mounting seat 100 by clamping, plugging, screwing or other means.

[0043] Specifically in this embodiment, the damping member 310 is connected to the armrest assembly 200, and the one-way rotating member 320 is connected to the mounting seat 100. The one-way rotating member 320 is set as a one-way bearing. In this way, when the user drives the armrest assembly 200 to rotate in the opening direction, the armrest assembly 200 drives the damping member 310, the adapter 330 and the inner ring of the one-way bearing to rotate synchronously. The outer ring of the one-way bearing is fixed to the mounting seat 100. At this time, the one-way bearing is in a rotating state, and the damping member 310 does not generate damping. The resistance received by the armrest assembly 200 is small and can be easily opened. When the user releases the armrest assembly 200 and the armrest assembly 200 rotates in the pressing direction under the action of its own gravity, since the one-way bearing can only rotate in one direction, the side of the damping member 310 close to the adapter 330, the adapter 330, the entire one-way bearing and the mounting seat 100 remain fixed, and the armrest assembly 200 drives the side of the damping member 310 away from the adapter 330 to rotate. At this time, the one-way bearing is in a self-locking state, and relative movement occurs on both sides of the damping member 310 to generate damping, so that the armrest assembly 200 has the function of freely hovering, can adapt to the experience needs of users of different heights, and improves the practicability of the armrest mechanism 10.

[0044] It should be noted that the one-way bearing being in a rotating state means the state when the inner ring of the one-way bearing can rotate relative to the outer ring. The one-way bearing being in a self-locking state means the state when the inner ring and the outer ring of the one-way bearing cannot rotate relative to each other.

[0045] In other embodiments, the damping member 310 may also be connected to the mounting base 100, and the one-way rotating member 320 is correspondingly connected to the armrest assembly 200. The working process is similar to the above, and will not be elaborated here.

[0046] As Figure 3 shown, optionally, a transmission shaft 331 is provided on a side of the adapter 330 close to the one-way rotating member 320, and the one-way rotating member 320 is fixedly sleeved on the transmission shaft 331.

[0047] Specifically in this embodiment, the one-way rotating member 320 is arranged as a one-way bearing. The outer ring of the one-way bearing is fixed on the mounting base 100 by keyway limit. The inner ring of the one-way bearing is fixed on the transmission shaft 331 of the adapter 330 by a keyway.

[0048] As Figure 3 shown, optionally, transmission protrusions 311 and transmission grooves 332 are respectively provided on sides of the damping member 310 and the adapter 330 close to each other, and the transmission protrusions 311 are in plug-in fit with the transmission grooves 332.

[0049] Specifically in this embodiment, the transmission protrusions 311 are provided on a side of the damping member 310 close to the adapter 330, and the transmission grooves 332 are provided on a side of the adapter 330 close to the damping member 310. The outer contour shape of the transmission protrusions 311 is adapted to the inner contour shape of the transmission grooves 332. The cross-section of the transmission protrusions 311 along a direction perpendicular to its own axis is non-circular. For example, the cross-section of the transmission protrusions 311 along a direction perpendicular to its own axis is a regular polygon. In other embodiments, the transmission protrusions 311 may also be provided on a side of the adapter 330 close to the damping member 310, and the transmission grooves 332 are correspondingly provided on a side of the damping member 310 close to the adapter 330.

[0050] As Figure 2 and Figure 3 shown, in one embodiment, the armrest assembly 200 includes a rotating shaft 210, and a first mounting groove 211 is provided at one end of the rotating shaft 210. The mounting base 100 includes a first stopper 110. The first stopper 110 is located at one end of the rotating shaft 210 where the first mounting groove 211 is provided. A second mounting groove 111 is provided on a side of the first stopper 110 close to the rotating shaft 210. The second mounting groove 111 and the first mounting groove 211 communicate to form a mounting cavity for mounting the first limiting component 300. In this way, the first limiting component 300 can be hidden inside the armrest mechanism 10, ensuring that the first limiting component 300 will not interfere with external objects and improving the reliability of the armrest mechanism 10.

[0051] As Figure 3As shown, optionally, the one-way rotating member 320 is installed in the second installation groove 111 and connected to the first stopper 110. An installation shaft 212 is provided on the bottom wall of the first installation groove 211; the damping member 310 is sleeved on the installation shaft 212; both sides of the damping member 310 along the rotation axis direction of the armrest assembly 200 are respectively connected to the rotating shaft 210 and the one-way rotating member 320, and is configured to relatively rotate when the rotating shaft 210 rotates in the pressing direction to generate damping.

[0052] Specifically in this embodiment, the damping member 310 includes a first group of metal sheets and a second group of metal sheets, and damping is generated when the first group of metal sheets and the second group of metal sheets perform relative rotational movement. The first group of metal sheets includes two metal sheets, and the second group of metal sheets includes one metal sheet. The first group of metal sheets is fixed to the rotating shaft 210 by screws. The second group of metal sheets is correspondingly connected to the adapter 330.

[0053] As Figure 2 and Figure 3 shown, in one embodiment, the mounting base 100 further includes a second stopper 120. The second stopper 120 is located at one end of the rotating shaft 210 away from the first installation groove 211. The second stopper 120 is fixedly connected to the first stopper 110 and is respectively in limit fit with both ends of the rotating shaft 210. In this way, the first stopper 110 and the second stopper 120 can cooperate to axially limit the armrest assembly 200, ensuring that the armrest assembly 200 does not move along its own rotation axis direction on the fuselage, and improving the reliability of the armrest mechanism 10.

[0054] As Figure 3 and Figure 4 shown, optionally, annular protrusions 121 and annular grooves 213 are respectively provided on the sides of the second stopper 120 and the rotating shaft 210 close to each other. The annular protrusion 121 is in plug-in fit with the annular groove 213 and is in rotational fit with the inner wall of the annular groove 213. The central axis of the annular groove 213 coincides with the rotation axis of the rotating shaft 210. In this way, the annular protrusion 121 and the annular groove 213 can cooperate to limit and guide the rotating shaft 210, ensuring that the armrest assembly 200 does not jump during the rotation process, and improving the safety of the armrest mechanism 10.

[0055] As Figure 3As shown, specifically in this embodiment, both the first stopper 110 and the second stopper 120 are in a plate-like structure. The bottom of the first stopper 110 is provided with a first supporting portion 112 extending towards the second stopper 120, and the bottom of the second stopper 120 is provided with a second supporting portion 122 extending towards the first stopper 110; the first supporting portion 112 and the second supporting portion 122 can be fixed together by screwing, clamping, plugging or other means, and can cooperate to support the rotating shaft 210. The contour shape of the side of the first supporting portion 112 close to the rotating shaft 210 and the contour shape of the side of the second supporting portion 122 close to the rotating shaft 210 are both adapted to the contour shape of the outer side wall of the rotating shaft 210.

[0056] Please refer to again Figure 1 , in an embodiment, the armrest assembly 200 includes a rotating shaft 210, a first armrest group 220 and a second armrest group 230. The rotating shaft 210 is rotatably arranged on the mounting base 100 and is connected to the first armrest group 220; the second armrest group 230 is telescopically matched with the first armrest group 220. Further, the second armrest group 230 is provided with a mounting portion 2331, and the mounting portion 2331 is used for mounting an interaction device or a peripheral device. In this way, the interaction device or the peripheral device can be mounted on the mounting portion 2331 and hover at different heights through the armrest mechanism 10 to adapt to users of different heights, improving the practicability of the armrest mechanism 10.

[0057] Specifically in this embodiment, the mounting portion 2331 can be set as a mounting bracket. The interaction device can be an interaction screen; the peripheral device can be a mobile terminal such as a tablet computer or a mobile phone.

[0058] Among them, the quantities of the rotating shaft 210, the first limiting component 300 and the mounting base 100 can all be flexibly adjusted according to actual usage needs. As Figure 2 and Figure 4 shown, optionally, there are two rotating shafts 210, two first limiting components 300 and two mounting bases 100. Both of the two rotating shafts 210 are connected to the first armrest group 220, and the rotation axes of the two rotating shafts 210 coincide. The two first limiting components 300 and the two mounting bases 100 are correspondingly arranged with the two rotating shafts 210. In this way, by the quantities of the rotating shaft 210, the first limiting component 300 and the mounting base 100, while ensuring the rotation stability of the armrest assembly 200, it also ensures that the armrest assembly 200 can stably and reliably hover at a specified height, improving the reliability of the armrest mechanism 10.

[0059] As Figure 1 and Figure 5, in one embodiment, another armrest mechanism 10 is provided. The armrest mechanism 10 is installed on the body of the machine device and includes an armrest assembly 200 and a locking assembly 400. The armrest assembly 200 includes a first armrest group 220 and a second armrest group 230. The first armrest group 220 is rotatably installed on the body and has a storage position; the second armrest group 230 is telescopically installed on the first armrest group 220 and has a retracted position. The locking assembly 400 is movably installed on the first armrest group 220 and has a locking position and a full-unlock position.

[0060] When the first armrest group 220 is in the storage position and the second armrest group 230 is in the retracted position, the locking assembly 400 can switch between the locking position and the full-unlock position, so that the locking cooperation between the first armrest group 220 and the second armrest group 230, and between the first armrest group 220 and the body is simultaneously locked or simultaneously unlocked.

[0061] Specifically in this embodiment, the locking assembly 400 further has a semi-unlock position; the second armrest group 230 further has a fully extended position. When the locking assembly 400 is in the semi-unlock position, the second armrest group 230 is in the fully extended position. At this time, the locking cooperation between the first armrest group 220 and the second armrest group 230 is maintained, while the locking cooperation between the first armrest group 220 and the body is released. When the second armrest group 230 is in a position between the retracted position and the fully extended position (i.e., the transitional state when the second armrest group 230 extends from the retracted position to the fully extended position), the locking assembly 400 is in the full-unlock position, and the locking cooperation between the first armrest group 220 and the second armrest group 230, and between the first armrest group 220 and the body are both released.

[0062] For the armrest mechanism 10 in the above embodiment, during use, the locking assembly 400 is used to control the simultaneous locking cooperation or simultaneous unlocking cooperation between the first armrest group 220 and the second armrest group 230, and between the first armrest group 220 and the body. It is ensured that when the locking assembly 400 is correspondingly moved out of the locking position, the second armrest group 230 can extend from the retracted position to release the locking cooperation between the first armrest group 220 and the body; when the second armrest group 230 extends to the fully extended position, the locking assembly 400 cannot automatically reset to the locking position, and the locking cooperation between the armrest assembly 200 and the body is released and maintained, so as to ensure that the armrest assembly 200 will not form a labor-saving lever structure to lift the body during the extended state, thereby improving the reliability and service life of the machine device.

[0063] Among them, the locking assembly 400 can be integrally movably installed on the first armrest group 220, or partially movably installed on the first armrest group 220. Specifically in this embodiment, the first armrest group 220 is rotatably installed on the mounting seat 100 through the rotating shaft 210, and the mounting seat 100 is installed on the fuselage. In other embodiments, the first armrest group 220 can also be directly rotatably installed on the fuselage.

[0064] As Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, optionally, the first armrest group 220 includes an armrest outer tube 221. One end of the armrest outer tube 221 is rotatably installed on the fuselage, and the other end is set as a free end 2211. Both sides of the free end 2211 are provided with first locking holes 2212. The second armrest group 230 includes an armrest inner tube 231 that telescopically cooperates with the armrest outer tube 221. Both sides of one end of the armrest inner tube 231 are respectively provided with second locking holes 2311 corresponding to the two first locking holes 2212, and the inner side of the other end is provided with a third locking hole 2312 corresponding to the first locking hole 2212. When the second armrest group 230 is in the retracted position, the third locking hole 2312 communicates with one of the two first locking holes 2212, and the armrest inner tube 231 blocks the other of the two first locking holes 2212; when the second armrest group 230 is in the fully extended position, the two first locking holes 2212 communicate with the two second locking holes 2311 correspondingly.

[0065] As Figure 5 , Figure 6 and Figure 7 shown, when the locking assembly 400 is in the locked position, the first armrest group 220 is in the stowed position, and the second armrest group 230 is in the retracted position. The locking assembly 400 can pass through the first locking hole 2212 corresponding to the third locking hole 2312, and the third locking hole 2312, and extend into the armrest inner tube 231, so that the first armrest group 220 and the second armrest group 230 are locked and cooperated. When the locking assembly 400 is in the fully unlocked position, when the first armrest group 220 is in the stowed position and the second armrest group 230 is in the retracted position, the locking assembly 400 can also correspondingly move out of the third locking hole 2312 and the first locking hole 2212, so that the locking cooperation between the first armrest group 220 and the second armrest group 230 is released.

[0066] As Figure 9 shown, when the locking assembly 400 is in the semi-unlocked position, the second armrest group 230 is in the fully extended position. Please combine Figure 5 and Figure 6It is understood that at this time, the locking assembly 400 passes through the two second locking holes 2311 and the two first locking holes 2212, so that the first armrest group 220 and the second armrest group 230 are locked, and the locking cooperation between the first armrest group 220 and the fuselage is released, that is, the so-called "half unlocking" is achieved. In this way, when the second armrest group 230 is in the fully extended position, both sides of the armrest inner tube 231 and both sides of the armrest outer tube 221 can be stressed, so that the stress area and stress balance of the locking assembly 400 are increased, and the overall strength and external force bearing performance of the armrest mechanism 10 are improved.

[0067] Furthermore, the second armrest group 230 can be configured with multiple extension positions, that is, two radially arranged second locking holes 2311 are a group, and the armrest inner tube 231 has multiple groups of second locking holes 2311, and each group of second locking holes 2311 is arranged at intervals along the axial direction of the armrest inner tube 231.

[0068] like Figure 8 As shown, when the locking assembly 400 is in the fully unlocked position, the second armrest group 230 is in a transition state between the retracted position and the fully extended position. Figure 6 It is understood that at this time, the locking assembly 400 extends into one of the two first locking holes 2212 and cooperates with the outer wall of the armrest inner tube 231 to limit the locking cooperation between the first armrest group 220 and the second armrest group 230, and between the first armrest group 220 and the fuselage are released.

[0069] like Figure 6 As shown, in one embodiment, the first armrest assembly 220 further includes a sliding sleeve 222, which is mounted on the free end 2211 and slidably cooperates with the armrest inner tube 231, and the two sides of the sliding sleeve 222 are respectively provided with fourth locking holes 2221 correspondingly connected to the two first locking holes 2212. In this way, the sliding sleeve 222 can guide the armrest inner tube 231, and the inner wall of the fourth locking hole 2221 on the sliding sleeve 222 can also contact the locking assembly 400 when the second armrest assembly 230 is in the extended state, so that the force bearing area of the locking assembly 400 is increased, and the stability and reliability of the armrest mechanism 10 are improved.

[0070] like Figure 6 and Figure 9 As shown, optionally, the second armrest assembly 230 further includes a second limiting assembly 232, which is installed at one end of the armrest inner tube 231 extending into the armrest outer tube 221. The second limiting assembly 232 is configured to cooperate with the sliding sleeve 222 when the second armrest assembly 230 is in a fully extended position. In this way, the armrest outer tube 221 limits the armrest inner tube 231 through the sliding sleeve 222 and the second limiting assembly 232, ensuring that the armrest inner tube 231 will not separate from the armrest outer tube 221, thereby improving the reliability of the armrest mechanism 10.

[0071] Among them, the second limiting component 232 can be set as a limiting block, a limiting frame, a limiting buckle or other limiting structures. The second limiting component 232 can be installed at one end of the inner armrest tube 231 extending into the outer armrest tube 221 by means of clamping, plugging, screwing or other connection methods.

[0072] Such as Figure 5 As shown, in one embodiment, the number of both the outer armrest tubes 221 and the inner armrest tubes 231 is two. The two outer armrest tubes 221 are arranged at intervals and are in corresponding telescopic cooperation with the two inner armrest tubes 231. The first armrest group 220 further includes a first connecting member 223. The two ends of the first connecting member 223 are correspondingly connected to the two free ends 2211, and the locking assembly 400 is installed on the first connecting member 223. In this way, the first connecting member 223 can increase the strength of the armrest assembly 200 while providing an installation basis for the locking assembly 400, improving the reliability and practicality of the armrest assembly 200.

[0073] Such as Figure 5 、 Figure 8 And Figure 9 As shown, further, the number of the locking assemblies 400 is two. The two locking assemblies 400 are respectively movably installed at the two ends of the first connecting member 223 and are correspondingly arranged with the two free ends 2211. When both of the two locking assemblies 400 are in the locked position, the distance between the two locking assemblies 400 is a first length (such as the length shown as D in Figure 5 ); when both of the two locking assemblies 400 are in the fully unlocked position, the distance between the two locking assemblies 400 is a second length (such as the length shown as E in Figure 8 ); when both of the two locking assemblies 400 are in the semi-unlocked position, the distance between the two locking assemblies 400 is a third length (such as the length shown as F in Figure 9 ). Among them, the third length is greater than the first length, and the first length is greater than the second length. In this way, by increasing the number of the locking assemblies 400, the connection strength between the outer armrest tube 221 and the inner armrest tube 231 is increased, improving the reliability of the armrest mechanism 10.

[0074] In other embodiments, the locking assembly 400 can also be one, and one locking assembly 400 is correspondingly installed at any one of the two ends of the connecting member.

[0075] Such as Figure 5 And Figure 6As shown, optionally, the first connecting member 223 is provided as a connecting pipe, and avoiding grooves 2231 extending along the axis direction of the pipe are provided on the outer side walls at both ends of the connecting pipe. The two ends of the connecting pipe communicate with the two free ends 2211 through the first locking holes 2212 correspondingly. The two locking assemblies 400 both include a first locking member 411, a second locking member 412 and a transmission member 413. The two first locking members 411 are respectively sleeved on the two ends of the connecting pipe in a sliding manner; the two second locking members 412 are respectively movably installed inside the two ends of the connecting pipe and are correspondingly arranged with the first locking holes 2212 on the two free ends 2211; the two transmission members 413 are respectively inserted through the two avoiding grooves 2231 and drive-connect the two first locking members 411 and the two second locking members 412. In this way, the connecting pipe can also play a guiding role to ensure that the first locking member 411 can drive the second locking member 412 to move along the axis direction of the first locking hole 2212, improving the reliability of the armrest mechanism 10.

[0076] Specifically in this embodiment, the second locking member 412 can be provided as a telescopic limit pin. The transmission member 413 can be provided as a transmission rivet. Please refer to Figure 1 and Figure 5 for understanding. The first locking member 411 can be provided as a locking sleeve, and a first reverse buckle 4111 is provided on the locking sleeve. The first reverse buckle 4111 is used for locking and engaging with the engaging groove on the fuselage. When the locking assembly 400 is in the semi-unlocked position or the fully unlocked position, along the axis direction of the connecting pipe, the first reverse buckle 4111 and the engaging groove are arranged in a dislocation manner so that they cannot be locked and engaged with each other. When the locking assembly 400 is in the locked position, along the axis direction of the connecting pipe, the first reverse buckle 4111 and the engaging groove are correspondingly arranged so that they can be locked and engaged with each other.

[0077] In other embodiments, the first reverse buckle 4111 can also be used for locking and cooperating with the second reverse buckle on the fuselage. When the locking assembly 400 is in the semi-unlocked position or the fully unlocked position, along the axis direction of the connecting pipe, the first reverse buckle 4111 and the second reverse buckle are arranged in a dislocation manner so that they cannot be locked and cooperated with each other. When the locking assembly 400 is in the locked position, along the axis direction of the connecting pipe, the first reverse buckle 4111 and the second reverse buckle are correspondingly arranged so that they can be locked and cooperated with each other.

[0078] Such as Figure 5 and Figure 6As shown, in one embodiment, the locking assembly 400 further includes an elastic reset member 414, which is installed in the connecting tube and is in contact with the second locking member 412. The elastic reset member 414 is configured to be compressed when the locking assembly 400 is in the fully unlocked position and the semi-unlocked position to apply an elastic reset force to the second locking member 412. In this way, the elastic reset member 414 can provide an elastic reset force for the second locking member 412, so that the second locking member 412 maintains a trend of moving toward the free end 2211, ensuring that the second locking member 412 can automatically pass through the first locking hole 2212 and the third locking hole 2312 and remain fixed when the second armrest group 230 is retracted to the retracted position, and the second locking member 412 can automatically pass through the first locking hole 2212 and the second locking hole 2311 and remain fixed when the second armrest group 230 is extended to the fully extended position, thereby improving the practicality of the armrest mechanism 10.

[0079] like Figure 5 and Figure 6 As shown, optionally, the first armrest assembly 220 further includes a mounting member 224, which is mounted on one end of the connecting pipe. A side of the mounting member 224 close to the free end 2211 is provided with a receiving groove 2241 corresponding to and communicating with the first locking hole 2212, and a side of the mounting member 224 away from the free end 2211 is provided with a mounting hole 2242 connected to the receiving groove 2241; the second locking member 412 is penetrated through the mounting hole 2242 and the receiving groove 2241, and the outer side wall of the part of the second locking member 412 located in the receiving groove 2241 is provided with a conflicting portion 4121; the elastic return member 414 is sleeved on the outer side wall of the second locking member 412, and the two ends of the elastic return member 414 are respectively in conflict with the conflicting portion 4121 and the bottom wall of the receiving groove 2241.

[0080] Specifically in this embodiment, the mounting member 224 can be configured as a mounting sleeve. The elastic reset member 414 can be configured as a compression spring. Both locking assemblies 400 include an elastic reset member 414, and the two elastic reset members 414 are configured correspondingly to the two second locking members 412. In other embodiments, the two locking assemblies 400 can also share one elastic reset member 414, and the elastic reset member 414 is located between the two second locking members 412 and is in conflict with the two second locking members 412.

[0081] like Figure 5 and Figure 6As shown, optionally, the first armrest group 220 further includes a second connecting member 225. The second connecting member 225 is provided with a connecting channel 2251 to sleeved the second connecting member 225 on the outer sidewall of the free end 2211. Fifth locking holes 2252 corresponding to and communicating with the two first locking holes 2212 are provided on both sides of the second connecting member 225. An annular flange 2253 extending around the axis of the fifth locking hole 2252 is provided on one side of the second connecting member 225 close to the locking assembly 400. The number of the second connecting members 225 is two, and the two second connecting members 225 are correspondingly arranged with the two free ends 2211. Both ends of the connecting pipe extend into the two annular flanges 2253 and are fixedly connected to the two annular flanges 2253.

[0082] Specifically in this embodiment, the second connecting member 225 is arranged in a T shape.

[0083] As Figure 5 shown, optionally, the first armrest group 220 further includes a decorative sleeve 226. The decorative sleeve 226 is sleeved on the connecting pipe to block at least part of the first locking member 411.

[0084] As Figure 1 and Figure 9 shown, optionally, one end of the inner armrest tube 231 away from the outer armrest tube 221 is set as a connecting end. The second armrest group 230 further includes a handle 233. Both ends of the handle 233 are correspondingly connected to the two connecting ends. A mounting portion 2331 is correspondingly arranged on the handle 233.

These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application.

[0086] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, if there is a term "plural", the meaning of "plural" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0087] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0088] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath", and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.

[0089] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0090] It should also be understood that when interpreting the connection relationship or position relationship of elements, although not explicitly described, the connection relationship and position relationship are interpreted to include an error range, and this error range should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximate", or "substantially" can mean within one or more standard deviations, which is not limited here.

[0091] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
