[0022] like Figure 1As shown, this utility model provides an armrest 1. It should be noted that the armrest 1 of this utility model can be applied not only to sofas, but also to other home furnishings, office supplies, and other products. The armrest 1 includes an armrest body 2 with a first receiving cavity 20, a fixed base 3 mounted on the armrest body 2, a guide bracket 5 and a multi-functional plate 6 mounted on the fixed base 3, and an auxiliary steering mechanism 4 connected to the multi-functional plate 6 and the guide bracket 5 respectively. The guide bracket 5 drives the multi-functional plate 6 to be housed in or removed from the first receiving cavity 20. When the multi-functional plate 6 is placed outside the first receiving cavity 20, the auxiliary steering mechanism 4 adjusts the relative position between the multi-functional plate 6 and the guide bracket 5, so that the user can adjust the multi-functional plate 6 to a suitable angle according to their usage habits and needs.

[0023] Combination Figure 2-8 As shown, the handrail body 2 can be rectangular in shape, having at least two adjacent side plates 21 and 22 (it should be noted that the length of the first side plate 21 is greater than the length of the second side plate 22) and an opening 210 located on one side and communicating with the first accommodating cavity 20. Preferably, the opening 210 is located on the first side plate 21.

[0024] The fixing base 3 is placed within the first accommodating cavity 20 and includes a first fixing piece 30 and a second fixing piece 31 that are perpendicular to each other and connected. The first fixing piece 30 and the second fixing piece 31 are respectively assembled onto adjacent side portions of the handrail body 2. Specifically, the first fixing piece 30 and the second fixing piece 31 are respectively installed onto the first side plate 21 and the second side plate 22 via threaded fittings. In this specific embodiment, the length of the first fixing piece 30 is greater than the length of the second fixing piece 31. Of course, in other specific embodiments, the length of the first fixing piece 30 may not be greater than the length of the second fixing piece 31. In an optional specific embodiment, the fixing base 3 can be integrally formed, and it can be formed by vertically bending the first fixing piece 30.

[0025] The auxiliary steering mechanism 4 includes a fixing part 41 mounted on the multi-functional plate 6 and a steering part 40 rotatably connected to the fixing part 41. The guide bracket 5 includes an "L"-shaped guide 50 and a hook part 51 fixed to one end of the guide 50. One end of the guide bracket 5 (i.e., the hook part 51) is rotatably connected to the second fixing plate 31 via a rotating shaft 10, so that the multi-functional plate 6 is either housed in the first receiving cavity 20 or disengaged from the first receiving cavity 20 through the opening 210 under the drive of the guide bracket 5; the other end (i.e., the other end of the guide 50) is rotatably connected to the steering part 40, and when the guide bracket 5 rotates to its maximum steering angle, the hook part 51 hooks onto the second fixing plate 31. The multi-functional plate 6 adjusts its relative position to the guide bracket 5 by rotating the steering part 40 relative to the fixing part 41 and / or by rotating the steering part 40 relative to the guide bracket 5 (see below for details), thereby allowing the multi-functional plate 6 to have multiple operating angles.

[0026] In one specific embodiment, when the steering part 40 rotates relative to the fixed part 41, the steering part 40 switches between a first relative position and a second relative position. Obviously, the first relative position and the second relative position are different. When the steering part 40 is in the first position (that is, the steering part 40 is placed in the clearance groove 60, see below for details), the length direction of the steering part 40 is parallel to the length direction of the fixed part 41; when the steering part 40 is in the second position, the length direction of the steering part 40 is perpendicular to the length direction of the fixed part 41.

[0027] In one specific embodiment, the steering unit 40 includes a steering body 400 and a first steering arm 401 and a second steering arm 402 extending from opposite side edges of the steering body 400 along the thickness direction of the steering body 400 (with a gap between the first steering arm 401 and the second steering arm 402). The shape and size of the first steering arm 401 are the same as those of the second steering arm 402, and the steering body 400, the first steering arm 401, and the second steering arm 402 together form a second receiving cavity 403. The second receiving cavity 403 is used to hold the head 411 of the fixing part 41 (the tail of the fixing part 41 is one end assembled to the multi-functional plate 6). During the rotation of the steering unit 40 relative to the fixing part 41, when the head 411 of the fixing part 41 is placed in or disengaged from the second receiving cavity 403, the steering unit 40 switches between a first relative position and a second relative position. It should be noted that the fixing part 41 is always stationary, and the turning part 40 rotates relative to the head 411 of the fixing part 41, causing the head 411 of the fixing part 41 to indirectly disengage from the second receiving cavity 403. In an optional embodiment, the turning part 40 may also be integrally formed.

[0028] In this specific embodiment, the steering body 400 can be disc-shaped. Of course, in other specific embodiments, the steering body 400 can also be other shapes.

[0029] In one specific embodiment, in order to enable the steering part 40 to switch between a first relative position and a second relative position during the rotation of the steering part 40 relative to the fixed part 41, the auxiliary steering mechanism 4 further includes a first positioning post 12 (not shown in the figure) and a second guide post 13 (not shown in the figure). Along the length direction of the steering part 40, the first steering arm 401 is provided with a second positioning hole 404 and a mounting hole 405, respectively. The corresponding positions of the second steering arm 402 are also provided with a second positioning hole 404 and a mounting hole 405. In contrast, the fixed part 41 includes a cantilever 410 fixed to the multi-functional plate 6 and a head 411 fixed to the cantilever 410 (in other specific embodiments, the fixed part 41 can also be integrally formed), and the head 411 is provided with a first positioning hole 4110 and an arc-shaped first guide hole 4111. The two ends of the first positioning hole 4110 are respectively connected to the second positioning hole 404 on the first steering arm 401 and the second positioning hole 404 on the second steering arm 402. At least a portion of the first guide hole 4111 is respectively connected to the mounting hole 405 on the first steering arm 401 and the mounting hole 405 on the second steering arm 402. One end of the first positioning post 12 passes through the second positioning hole 404 on the first steering arm 401 through the first positioning hole 4110 and into the second positioning hole 404 on the second steering arm 402. One end of the second guide post 13 passes through the mounting hole 405 on the first steering arm 401 through the first guide hole 4111 and into the mounting hole 405 on the second steering arm 402. In other words, the first positioning post 12 is sequentially inserted into the second positioning hole 404 on the first steering arm 401, the first positioning hole 4110, and the second positioning hole 404 on the second steering arm 402, while the second guide post 13 is sequentially inserted into the mounting hole 405 on the first steering arm 401, the first guide hole 4111, and the mounting hole 405 on the second steering arm 402. The first positioning post 12 defines the relative position of the first steering arm 401 and the second steering arm 402 with respect to the head 411, and the rotation of the steering part 40 relative to the fixed part 41 is achieved by the movement of the second guide post 13, which is installed at both ends in the mounting holes 405 of the first steering arm 401 and the mounting holes 405 of the second steering arm 402, within the first guide hole 4111.

[0030] In one specific embodiment, a first guide post 4001 is mounted on the outer end face of the steering part 40, and a third positioning hole 4000 is provided on the steering part 40. Correspondingly, a fourth positioning hole 500 communicating with the third positioning hole 4000 and an arc-shaped second guide hole 501 for supplying the first guide post 4001 with reciprocating motion are provided on the other end of the guide bracket 5. The auxiliary steering mechanism 4 also includes a second positioning post 14, which is sequentially inserted into the third positioning hole 4000 and the fourth positioning hole 500. The second positioning post 14 defines the relative position between the guide bracket 5 and the steering part 40, and the first guide post 4001 mounted on the steering part 40 moves within the second guide hole 501 to realize the rotation of the steering part 40 relative to the fixed part 41.

[0031] In one specific implementation, refer to Figure 3 In order to prevent the steering part 40 and the guide bracket 5 from wearing each other during the rotation of the steering part 40 relative to the guide bracket 5, a wear-resistant pad 7 is provided between the other end of the guide bracket 5 (that is, the other end of the guide member 50) and the outer end face of the steering part 40.

[0032] In one specific embodiment, to make the multi-functional panel 6 aesthetically pleasing, a recessed clearance groove 60 is formed on one side edge of the multi-functional panel 6. Obviously, when the steering part 40 is in the first relative position, the auxiliary steering mechanism 4 is placed within the clearance groove 60. In this specific embodiment, the clearance groove 60 can be approximately square in shape. Of course, in other specific embodiments, the clearance groove 60 can also have other shapes.

[0033] In one specific embodiment, in order to increase the connection strength between the multifunctional plate 6 and the fixing part 41, a reinforcing plate 8 is installed on one side of the multifunctional plate 6, and a reinforcing rib 80 extends from the reinforcing plate 8. Along the thickness direction of the cantilever 410, the reinforcing rib 80 is stacked on the cantilever 410 and fixed to the head 411 by fasteners 11.

[0034] In one specific implementation, refer to Figure 1 On one side of the handrail 1, near the opening 210, there is a groove 211 for the guide bracket 5 to extend from the first receiving groove. When part of the guide bracket 5 extends out of the first receiving cavity 20 through the groove 211, the guide bracket 5 also drives the multi-functional plate 6 to come out of the first receiving cavity 20. At this time, the user can cover the opening 210 with the mounting plate 23 to seal the first receiving cavity 20.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
