[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0027] See also Figures 1 to 7 The aircraft seat lifting armrest provided in an embodiment of the present invention includes a skeleton assembly 100, a locking and unlocking mechanism 200 and a linear slide rail limiting mechanism 300. The locking and unlocking mechanism 200 is fixed on the skeleton assembly 100. The linear slide rail limiting mechanism 300 is slidably connected with the skeleton assembly 100, so that the skeleton assembly 100 can slide relative to the linear slide rail limiting mechanism 300, thereby realizing the lifting and lowering of the aircraft seat armrest. The locking and unlocking mechanism 200 can limit the sliding of the skeleton assembly 100.

[0028] Specifically, a left slider 400 and a right slider 500 are fixedly provided on the skeleton assembly 100. The left slider 400 and the right slider 500 are arranged in parallel and spaced apart. The left slider 400 and the right slider 500 can slide relative to the linear slide rail limiting mechanism 300, thereby realizing the lifting and lowering of the aviation seat armrest.

[0029] The linear slide rail limiting mechanism 300 includes a side support plate 310, a left slide rail 320, a right slide rail 330, a lower blocking member 340 and an upper blocking member 350. The left slide rail 320 and the right slide rail 330 are both fixedly arranged on the side support plate 310. The left slider 400 is slidably connected to the left slide rail 330. The right slider 500 is slidably connected to the right slide rail 340. The lower blocking member 340 is fixed on the right slide rail 330. The upper blocking member 350 is fixed on the side support plate 310. When the right slider 500 slides to the position of the lower blocking member 340, the lower blocking member 340 abuts against the right slider 500 and prevents the right slider 500 from continuing to slide along the current sliding direction.

[0030] The locking and unlocking mechanism 200 is fixed on the frame assembly 100 . When the left slider 400 slides to the position of the upper blocking member 350 , the upper blocking member 350 and the locking and unlocking mechanism 200 are limited so that the left slider 400 slides and is limited.

[0031] Specifically, when the height of the armrest of the airline seat needs to be lowered, the frame assembly 100 is slid so that the left slider 400 and the right slider 500 slide downward in the left slide rail 320 and the right slide rail 330 respectively. At this time, the height of the frame assembly 100 is reduced. When the right slider 500 slides to the position of the lower blocking member 340, the right slider 500 abuts against the lower blocking member 340, and the lower blocking member 340 supports the right slider 500, so that the entire frame assembly 100 cannot continue to move downward, thereby achieving the armrest at the lowest limit. When the height of the armrest of the airline seat needs to be raised, the frame assembly 100 is slid so that the left slider 400 and the right slider 500 slide upward in the left rail 320 and the right rail 330 respectively. At this time, the height of the frame assembly 100 is raised. When the left slider 400 slides to the position of the upper blocking member 350, the locking and unlocking mechanism 200 gradually limits the position with the upper blocking member 350 during the movement of the frame assembly 100, so that the left slider 400 slides and limits the position, thereby realizing the function of locking the armrest in the highest position. When unlocking is required, the unlocking button on the locking and unlocking mechanism 200 can be pressed to separate the locking and unlocking mechanism 200 from the upper blocking member 350, thereby realizing the function of quickly unlocking the armrest in the highest position.

[0032] The present invention realizes the lifting and lowering movement of the armrest by arranging two sliders on the frame assembly 100 and sliding the sliders on the linear slide rail limiting mechanism 300. At the same time, by arranging an upper blocking member 350 and a lower blocking member 340 on the linear slide rail limiting mechanism 300, the movement of the frame assembly 100 at the lowest position can be limited. At the same time, when the frame assembly 100 is in the highest position, the locking and unlocking mechanism 200 and the upper blocking member 350 are limited to achieve rapid locking at the highest position, thereby providing convenience for passengers to get on and off the seat.

[0033] In the preferred embodiment, please continue to refer to Figure 3 The lower blocking member 340 is a limit pin with a simple structure. When the right slider 500 slides to the limit pin position, the limit pin can easily resist the right slider 500, so that the right slider 500 cannot continue to slide downward, thereby achieving limitation at the lowest position.

[0034] Please continue reading Figure 3 The upper blocking member 350 includes a locking block 351 and a locking tongue 352. The locking block 351 is provided with a pin hole 351a. The locking tongue 352 is fixedly connected to the locking block 351 and is located at the pin hole 351a. When the left slider 400 slides to the position of the locking block 351, the locking and unlocking mechanism 200 pushes open the locking tongue 352 and falls into the pin hole 351a, so that the locking block 351 and the locking and unlocking mechanism 200 are limited.

[0035] Specifically, the top end of the lock tongue 352 has a slope. When the skeleton assembly 100 moves upward to the position of the locking block 351, the locking and unlocking mechanism 200 contacts the lock tongue 352, and then the locking and unlocking mechanism 200 continues to move upward with the skeleton assembly 100. When the locking and unlocking mechanism 200 moves to the slope position, the locking and unlocking mechanism 200 passes over the slope and extends into the pin hole 351a of the locking block 351, thereby limiting the position of the locking block 351, thereby realizing the function of locking the armrest at the highest position.

[0036] Please also read Figure 4 and Figure 5 The locking and unlocking mechanism 200 includes a support assembly 210, a locking pin 220, a button 230, an inclined support arm 240, a compression spring 250 and a retaining spring 260. The support assembly 210 is fixedly arranged on the frame assembly 100. The support assembly 210 has a first accommodating cavity, and a mounting block 270 is fixedly arranged in the first accommodating cavity. The locking pin 220, the inclined support arm 240, the compression spring 250 and the retaining spring 260 are all located in the first accommodating cavity. One end of the locking pin 220 passes through the mounting block 270 and the compression spring 250 and extends out of the first accommodating cavity. The retaining spring 260 is fixedly connected to the locking pin 220 and is used to limit the length of the locking pin 220 extending out of the first accommodating cavity. One end of the compression spring 250 is fixed to the mounting block 270 and the compression spring 250. The retaining spring 260 is abutted, the other end of the compression spring 250 is abutted against the mounting block 270, one end of the inclined support arm 240 is fixedly connected to the other end of the locking pin 220, the button 230 is fixed on the supporting assembly 210, and the ejection rod of the button 230 extends into the first accommodating cavity, and the other end of the inclined support arm 240 is abutted against the ejection rod of the button 230; when the locking block 351 and the locking and unlocking mechanism 200 are limited, the locking pin 220 is inserted into the pin hole 351a, and when the locking block 351 and the locking and unlocking mechanism 200 need to be released from the limit, by pressing the button 230, the inclined support arm 240 drives the locking pin 220 to move toward the first accommodating cavity to disengage from the pin hole 351a.

[0037] Specifically, the locking pin 220 is a pin rod that cooperates with the locking block 351 and can extend into the pin hole 351a of the locking block 351. The retaining spring 260 installed on the locking pin 220 is used to limit the length of the locking pin protruding from the first accommodating cavity. At the same time, the retaining spring 260 and the mounting block 270 can also form a pre-compression on the compression spring 250. The button 230 is used to unlock the locking pin 220 and the locking block 351. In specific implementation, when the left slider 400 slides to the position of the locking block 351, the locking pin 220 contacts the locking tongue 352. Under the top pressure of the locking tongue 352, one end of the locking pin 220 gradually extends into the first accommodating cavity. When the locking pin 220 moves into the first accommodating cavity, the retaining spring 260 and the mounting block 270 compress the compression spring 250, so that the compression spring 250 has a certain rebound force. When the locking pin 220 passes over the inclined surface at the top end of the locking tongue 352, the locking pin 220 presses down the locking tongue 352. At the same time, the rebound force of the compression spring 250 is applied to the retaining spring 260. The retaining spring 260 drives the locking pin 220 to be inserted into the pin hole 351a of the locking block 351, thereby realizing the locking of the armrest at the highest position. When unlocking is required at the highest position, the user only needs to press the button 230, and the ejector rod of the button 230 presses the other end of the inclined support arm 240 to move the inclined support arm 240. When the inclined support arm 240 moves, it drives the locking pin 220 to move along the pin hole 351a and gradually disengages from the pin hole 351a. During the movement of the locking pin 220, the retaining spring 260 and the mounting block 270 compress the compression spring 250. When the locking pin 220 completely disengages from the pin hole 351a, the reaction force of the compression spring 250 is applied to the retaining spring 260, so that the locking pin 220 returns to its initial position under the reaction force, thereby realizing the rapid unlocking of the armrest at the highest position.

[0038] For further embodiments, please refer to Figure 4 The support assembly 210 includes a support frame 211, an armrest cover 212 and a plurality of hinges 213. The armrest cover 212 is rotatably connected to the support frame 211 through the plurality of hinges 213. The support frame 211 has the first accommodation cavity. The armrest cover 212 can be covered on the support frame 211 to facilitate the user to hold the armrest by hand. The hinges 213 facilitate the opening and closing of the armrest cover 212.

[0040] Specifically, the sheet metal assembly 110 can provide effective support for the entire armrest, and the second accommodating cavity of the sheet metal assembly 110 can be a semi-enclosed storage space for accommodating items, such as dining tables and other components, so that the entire aviation seat is more integrated, and the outer PC decorative panel 120 and the inner PC decorative panel 130 play a decorative role. Among them, the inner PC decorative panel 130 is composed of a first decorative panel 131 and a second decorative panel 132, which facilitates the assembly of the entire skeleton assembly 100.
