Detailed Description

The invention will be further described with reference to specific embodiments and the accompanying drawings.

Referring to fig. 1 to 3, an expandable aviation seat armrest includes an armrest body 100, an expansion plate 200, a link mechanism 300, and a limit mechanism 400. An expansion board 200 which is turned between an unfolding position and a storage position is hinged on the armrest body 100. The expansion board 200 is turned to the unfolding position, a temporary supporting surface can be formed, and the supporting width of the handrail is enlarged, so that the passengers can conveniently place the arms, and the comfort is improved. When the expansion board 200 is turned to the storage position, the expansion board 200 is stored in the armrest body 100, and the standing or sitting of the passenger is not affected.

The expansion board 200 is hinged to the link mechanism 300, and the link mechanism 300 is hinged to the limiting mechanism 400. The link mechanism 300 feeds back the turning state of the expansion board 200, and the link mechanism 300 is synchronously driven to move when the expansion board 200 moves. The limiting mechanism 400 is clamped on the link mechanism 300 at the unfolding position and the accommodating position, and the expansion board 200 is ensured to be stable in two states by clamping the link mechanism 300.

The armrest body 100 has a rectangular cross section, and the rear end is hinged and the height gradually decreases forward. A mounting notch is formed between both side plates and the top plate of the armrest body 100, and the mounting notch is used for mounting the extension plate 200. The extension panels 200, which are hinged on both sides, allow for extension of the width of both sides of the handrail, providing a temporary support surface for both passengers on both sides.

The expansion board 200 is flush with the upper end surface of the armrest body 100 at the expansion position, so that the comfort level is prevented from being affected by the formation of a step structure. The expansion board 200 is at the side end face parallel and level of accomodating position and handrail body 100, avoids forming the stair structure and influences the comfort level, avoids the expansion board to stretch out when accomodating simultaneously and additionally takes up space.

The expansion plate 200 includes a hinge portion 201, a side plate body 202, an end plate body 203, a lower plate body 204 and a hinge plate 205, wherein the side plate body 202 is a main acting surface of the support. The upper part of the side plate 202 is integrally connected with a hinge 201, and the hinge 201 is hinged with the armrest body 100 through a hinge shaft 406, so that the turning and hinging connection of the side plate 202 is completed.

The front end and the rear end of the side plate body 202 are vertically and integrally connected with an inward end plate body 203, the lower part of the side plate body 202 is vertically connected with an inward lower plate body 204, and the end plate body 203 and the lower plate body 204 are used for edge covering of the side plate body 202, so that an edge structure is prevented from being generated at the edge of the side plate body 202. The connecting inner corners of the side plate body 202 and the lower plate body 204 are welded to connect hinge plates 205, and the hinge plates 205 are hinged with the link mechanism 300 through hinge shafts 406, so that the link mechanism 300 supports and limits the side plate body 202.

The link mechanism 300 comprises a rocker 301 and a connecting rod 302, one end of the rocker 301 hinged with the limiting mechanism 400 is provided with a limiting part 303, and the limiting mechanism 400 comprises a top block 401, a pressure spring 402, a pressure spring seat 403, a limiting pin 404 and a limiting seat 405.

The pressure spring seat 403 and the limiting seat 405 are fixed in the handrail body 100, and the limiting pin 404 is fixed in the middle of the limiting seat 405. The inner end of the rocker 301 is hinged with the limit seat 405 through the hinge shaft 406, the outer end of the rocker 301 is hinged with the inner end of the connecting rod 302 through the hinge shaft 406, the outer end of the connecting rod 302 is hinged with the hinge plate 205 through the hinge shaft 406, and through the structure of the hinge rod, when the expansion plate 200 is in two states, the limit part 303 is also in two states.

The stopper pin 404 is locked to the stopper portion 303, and supports the horizontal state of the expansion board 200 when it is unfolded, thereby forming a fixed locking structure. The ejector block 401 is vertically sleeved on the pressure spring seat 403, a pressure spring 402 is arranged between the pressure spring seat 403 and the ejector block 401, and the pressure spring 402 provides elasticity for the ejector block 401, so that when the limiting portion 303 is switched between two positions, the elasticity needs to be overcome, and an elastic clamping structure is formed.

In the storage position, the rocker 301 and the connecting rod 302 are folded, the top block 401 is clamped with the inner side surface of the limiting part 303, and at the moment, the elastic force needs to be overcome when the expansion board 200 is opened. At the position of expanding, rocker 301 and connecting rod 302 expand, but because a < b + c this moment, wherein a is the articulated center interval in outer end of connecting rod 302 and the articulated center interval in rocker 301 inner, b is the articulated center interval at rocker 301 both ends, c is the articulated center interval at connecting rod 302 both ends, cause the middle part pin joint of connecting rod 302 of rocker 301 to take place flagging, and the pressure of expansion board 200 can make the middle part pin joint of rocker 301 continue to fall, spacing pin 404 is established with the medial surface card of spacing portion 303 this moment, the realization is dead to the lock of rocker 301, form stable support to expansion board 200. Meanwhile, the top block 401 is clamped with the outer side face of the limiting portion 303, and when the middle hinge point of the rocker 301 is pushed upwards to be stored, the elastic force needs to be overcome.

In order to reduce the space structure, a limit seat 405 supports the rockers 301 on both sides, and a limit pin is also used for clamping the limit parts on both sides. The stopper 303 has an outwardly-facing tapered head structure, and can move the top block 401 outward to further reduce the space.

The foregoing basic embodiments of the invention and their various further alternatives can be freely combined to form multiple embodiments, all of which are contemplated and claimed herein. In the scheme of the invention, each selection example can be combined with any other basic example and selection example at will.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
