Especially in the scenario of sitting for a long time, higher requirements are put forward for the functionality and adaptability of seat armrests. Although the design of traditional seat armrests has made some progress, they are generally limited to basic lifting and rotation adjustments. Due to factors such as height, arm length, work nature, and personal preferences of different users, the requirements for the height, angle, and even the linkage with the backrest of the armrest vary.

[0074] the multifunction adjustable seat armrests are connected to the seat frame through connecting arms.

[0075] The beneficial effects of the present utility model are:

[0076] (1). Before the rotary support arm starts to rotate, the top of the first positioning ball screw is stuck in the corresponding first spherical recess. When the user starts to rotate the rotary support arm, the rotary support arm rotates relative to the rotary base. When the top of the first positioning ball screw aligns with the opening of a certain first spherical recess, the first positioning ball screw will be compressed and slightly enter the first spherical recess. As the rotary support arm continues to rotate, the first positioning ball screw completely enters the first spherical recess and gets stuck therein, achieving a temporary locked state. If the user continues to rotate the rotary support arm, the top of the first positioning ball screw will sequentially pass through and be stuck in the next first spherical recess, and so on. When the rotary support arm rotates to the position desired by the user, the user stops rotating, and the top of the first positioning ball screw is stuck in the corresponding first spherical recess, locking the rotary support arm at this position. Due to the elastic effect of the first positioning ball screw, once it is stuck in the first spherical recess, a certain external force is required to pull it out of the first spherical recess, thereby ensuring the stability of the rotary support arm in the locked state; if the user needs to adjust the angle of the armrest, just slightly rotate the rotary support arm with a little force to pull the top of the first positioning ball screw out of the current first spherical recess, then rotate to a new position and lock it again.

[0077] (2). In the initial state, the square block is located in the square block placement part and the square block placement through part, limiting the rotation of the connecting piece. At this time, the user cannot freely rotate the connecting piece. When the user presses the button, the button slides in the button placement part and the button placement through part and compresses the first elastic member. The movement of the button drives the square block to slide from the square block placement part into the square block placement through part through the rotating shaft, thereby canceling the rotation limit of the connecting piece. When the square block enters the square block placement through part, the connecting piece can rotate freely, and the user can adjust the angle of the connecting piece as needed. When the connecting piece is reset, release the button, and under the action of the elastic deformation of the first elastic member, the button and the square block will automatically reset, and the square block re-enters the square block placement part and the square block placement through part to limit the rotation of the connecting piece. Through the above steps, the effects of flexible control and limitation are achieved.

[0078] (3) When the support plate needs to be rotated, push the support plate so that the cylindrical part rotates around the second circular boss at the bottom of the fixing part by a certain angle. At this time, the support plate drives the rotating lock and the second elastic member in the first mounting position to rotate together. When the rotating lock rotates to contact the convex part of the first wave part, due to the obstruction of the convex part, the rotating lock cannot continue to rotate in the original direction. At this time, the second elastic member is slightly compressed. As the support plate continues to rotate, the rotating lock will rotate to a position aligned with the concave part of the first wave part. At this time, the rotating lock automatically snaps into the concave part under the resilience of the second elastic member, realizing the locking of the support plate. Through the above steps, the effects of automatic locking and flexible adjustment are achieved.

[0079] (4) The support plate is placed in the support plate moving position of the armrest seat and is slidably connected to the first circular boss through the long through hole. The armrest seat can be translated in the horizontal direction. When the armrest seat is translated, the second wave parts on both sides of the armrest seat interact with the two clamping members. When the clamping member encounters the convex part of the second wave part, it is obstructed and compresses the third elastic member. As the armrest seat continues to be translated, the concave part of the second wave part moves to a position aligned with the clamping member. At this time, the third elastic member rebounds and pushes the clamping member to snap into the concave part of the second wave part, realizing the locking of the armrest seat. Apply a little external force to disengage the concave part of the second wave part from the clamping member, and the armrest seat can continue to be translated to the next locking position. Through the above steps, the effect of automatic locking is achieved.

[0080] (5) Through multiple precisely designed components, including the telescopic arm, the first rotating component, the tilting component, the second rotating component, the translation component and their related locking components, the all-round adjustment and locking of the armrest in terms of height, angle, tilt and horizontal position are realized, meeting the personalized and comfortable needs of different users for the seat armrest and improving the quality of work and life.

Embodiment 1

[0103] As Figures 1 to 11 shown, this embodiment provides a multifunctional adjustable seat armrest, including:

[0104] The telescopic arm 1 and the connecting arm 6 connected to the telescopic arm 1; the first rotating assembly 2, which includes: a rotating base 201 provided at the top of the telescopic arm 1 and a rotating support arm 202 rotatably connected to the rotating base 201; the tilting assembly 3, which includes: a connecting member 301 hinged to the top of the other end of the rotating support arm 202; the second rotating assembly 4, which includes: a fixing member 401 provided on the connecting member 301 and a support plate 402 rotatably connected to the fixing member 401; the translation assembly 5, which includes: an armrest seat 501 provided between the support plate 402 and the connecting member 301; wherein the armrest seat 501 is slidably connected to the support plate 402 and the connecting member 301; wherein the telescopic arm 1 is used to adjust the height of the armrest; wherein the connecting arm 6 is used to connect to the seat; by providing the rotating base 201 and the rotating support arm 202, the effect of adjusting the angle of the armrest is achieved; wherein by providing the connecting member 301, the effect of adjusting the tilting angle of the armrest is achieved; wherein by providing the fixing member 401 and the support plate 402, the effect of finely adjusting the rotating angle of the armrest is achieved; wherein by the sliding connection of the armrest seat 501 with the support plate 402 and the connecting member 301, the effect of adjusting the position of the armrest is achieved.

[0105] The first rotating assembly 2 further includes: a first bearing 203 provided between the rotating base 201 and the rotating support arm 202; a first placement portion 2011 is provided at the top of the rotating base 201; a second placement portion 2021 is provided at the bottom of the rotating support arm 202; wherein the first bearing 203 is located within the first placement portion 2011 and the second placement portion 2021; wherein the first bearing 203 is most preferably a ball bearing; by providing the first bearing 203, the friction between the rotating base 201 and the rotating support arm 202 is reduced, making the rotation smoother; by providing the first placement portion 2011 and the second placement portion 2021, precise positioning and fixing of the first bearing 203 are achieved, ensuring its stability and reliability during rotation.

[0106] The top of the rotating base 201 is provided with a second placement hole 2012 and symmetrically arranged first placement holes 2013; the bottom of the rotating support arm 202 is provided with a second spherical recess 2022 and a number of first spherical recesses 2023 arranged in a circular array; the first rotating assembly 2 further includes: a second positioning ball screw 204 arranged in the second placement hole 2012 and a first positioning ball screw 205 arranged in the first placement hole 2013; wherein the top of the second positioning ball screw 204 is located in the second spherical recess 2022 in the initial state; and the top of the first positioning ball screw 205 is adapted to be successively snapped into the corresponding first spherical recesses 2023 when the rotating support arm 202 rotates; wherein by arranging a number of first spherical recesses 2023 arranged in a circular array, the rotating support arm 202 can be locked at multiple angles; by arranging symmetrically arranged first positioning ball screws 205, the rotation of the rotating support arm 202 is made more stable, and secondly, when the first positioning ball screw 205 is snapped into the first spherical recess 2023, the effects of precise positioning and locking are achieved; wherein the second positioning ball screw 204 is adapted to re-enter the second spherical recess 2022 only after rotating one circle to position the armrest (for example, when the armrest is perpendicular to the backrest).

[0107] In this embodiment, before the rotating support arm 202 starts to rotate, the top of the first positioning ball screw 205 is stuck in the corresponding first spherical recess 2023. When the user starts to rotate the rotating support arm 202, the rotating support arm 202 rotates relative to the rotating base 201. When the top of the first positioning ball screw 205 aligns with the opening of a certain first spherical recess 2023, the first positioning ball screw 205 will be compressed and slightly enter the first spherical recess 2023. As the rotating support arm 202 continues to rotate, the first positioning ball screw 205 completely enters the first spherical recess 2023 and is stuck therein, achieving a temporary locking state. If the user continues to rotate the rotating support arm 202, the top of the first positioning ball screw 205 will successively pass through and be snapped into the next first spherical recess 2023, and so on. When the rotating support arm 202 rotates to the position desired by the user, the user stops rotating, and the top of the first positioning ball screw 205 is snapped into the corresponding first spherical recess 2023 to lock the rotating support arm 202 at this position. Due to the elastic action of the first positioning ball screw 205, once it is snapped into the first spherical recess 2023, a certain external force is required to pull it out of the first spherical recess 2023, thereby ensuring the stability of the rotating support arm 202 in the locked state; if the user needs to adjust the angle of the armrest, just slightly rotate the rotating support arm 202 with a little force to pull the top of the first positioning ball screw 205 out of the current first spherical recess 2023, and then rotate to a new position and re-lock it.

[0108] Since the second positioning detent screw 204 and the first positioning detent screw 205 have the same function, and the second spherical recess 2022 and the first spherical recess 2023 have the same function except for the number, their actual function is to position the armrest (for example, when the armrest is perpendicular to the backrest), and no more description will be given here.

[0109] The first rotating assembly 2 further includes: a flat head nut 206 passing through the rotating base 201 and a bolt 207 passing through the rotating support arm 202; wherein the bolt 207 meshes with the flat head nut 206 to limit the rotating base 201 and the rotating support arm 202; a bolt placement portion 2024 for accommodating the head of the bolt 207 is provided at the top of the rotating support arm 202; the first rotating assembly 2 further includes: a second bearing 208 provided in the bolt placement portion 2024 and a decorative cover 209 snap-fitted to the bolt placement portion 2024; wherein the bolt 207 is adapted to pass through the second bearing 208 and then mesh with the flat head nut 206; the second bearing 208 is most preferably a ball bearing; by providing the flat head nut 206 and the bolt 207, the rotating base 201 and the rotating support arm 202 are limited to prevent relative movement between them; by providing the second bearing 208, the friction and wear between the bolt 207 and the rotating support arm 202 are reduced, enabling the rotating support arm 202 to rotate smoothly; by providing the decorative cover 209, the bolt placement portion 2024 is covered and beautified, while protecting the internal second bearing 208 and bolt 207 from external contamination.

[0110] A hinge portion 2025 is provided at the top of the rotating support arm 202; a first limiting platform 2026 is provided in the hinge portion 2025; a second limiting platform 3011 is provided at the bottom of the connecting member 301; when the connecting member 301 rotates a certain angle within the hinge portion 2025, the first limiting platform 2026 contacts the second limiting platform 3011; by providing the first limiting platform 2026 and the second limiting platform 3011, the connecting member 301 is prevented from exceeding a predetermined safe range during rotation, avoiding damage or instability caused by excessive rotation.

[0111] The inclined component 3 further includes: a rotating shaft 302 passing through the connecting member 301, a square block 303 connected to one end of the rotating shaft 302, a button 304 connected to the other end of the rotating shaft 302, and a first elastic member 305 sleeved on the rotating shaft 302; a square block placement portion 3012 is provided on one side of the connecting member 301; a square block placement through portion 20251 is provided on one side of the hinge portion 2025; wherein the square block 303 is adapted to be slidably connected to the square block placement portion 3012 and the square block placement through portion 20251; and when the square block 303 is located in the square block placement portion 3012 and the square block placement through portion 20251, the rotation of the connecting member 301 is limited; when the square block 303 is located in the square block placement through portion 20251, the rotation limit of the connecting member 301 is cancelled; a button placement through portion 20252 is provided on the other side of the hinge portion 2025; a button placement portion 3013 is provided on the other side of the connecting member 301; wherein the button 304 is adapted to be slidably connected to the button placement through portion 20252 and the button placement portion 3013; and the first elastic member 305 is located between the button 304 and the button placement portion 3013; when the button 304 is pressed, it retracts into the button placement through portion 20252 and compresses the first elastic member 305 with the button placement through portion 20252; the button 304 is adapted to drive the rotating shaft 302 and the square block 303 to move when moving; wherein the first elastic member 305 is, but not limited to, a spring.

[0112] In this embodiment, in the initial state, the square block 303 is located in the square block placement portion 3012 and the square block placement through portion 20251, limiting the rotation of the connecting member 301. At this time, the user cannot freely rotate the connecting member 301. When the user presses the button 304, the button 304 slides in the button placement portion 3013 and the button placement through portion 20252 and compresses the first elastic member 305. The movement of the button 304 drives the square block 303 to slide from the square block placement portion 3012 into the square block placement through portion 20251 through the rotating shaft 302, thereby canceling the rotation limit of the connecting member 301. When the square block 303 enters the square block placement through portion 20251, the connecting member 301 can rotate freely, and the user can adjust the angle of the connecting member 301 as needed. When the connecting member 301 is reset, the button 304 is released. Under the action of the elastic deformation of the first elastic member 305, the button 304 and the square block 303 will automatically reset, and the square block 303 re-enters the square block placement portion 3012 and the square block placement through portion 20251 to limit the rotation of the connecting member 301. Through the above steps, the effects of flexible control and limitation are achieved.

[0113] The top of the connecting member 301 is provided with a first circular boss 3014; the top of the first circular boss 3014 is provided with a special-shaped boss 3015; the bottom of the fixing member 401 is provided with a second circular boss 4011; the bottom of the second circular boss 4011 is provided with a special-shaped recess 4012 adapted to the special-shaped boss 3015; wherein the fixing member 401 and the special-shaped boss 3015 are adapted to be connected by screws; the support plate 402 is provided with a fixing member rotating portion 4021, a circular through portion 4022 arranged in the fixing member rotating portion 4021, and first mounting positions 4023 arranged on both sides of the fixing member rotating portion 4021; wherein the two first mounting positions 4023 communicate with the fixing member rotating portion 4021; and the second circular boss 4011 is rotatably connected to the circular through portion 4022; the second rotating assembly 4 further includes: a rotating lock 403 arranged in the first mounting position 4023 and a second elastic member 404; wherein one end of the second elastic member 404 is sleeved on the rotating lock 403; and the other end of the second elastic member 404 abuts against the side wall of the first mounting position 4023; both sides of the fixing member 401 are provided with first wave portions 4013; wherein the rotating lock 403 is adapted to be snapped into the recess of the first wave portion 4013; four limiting portions 4024 are arranged in the fixing member rotating portion 4021; wherein the fixing member 401 is adapted to be limited by the convex portion of the first wave portion 4013 when rotating a certain angle; wherein the second elastic member 404 is, but not limited to, a spring; wherein by arranging four limiting portions 4024 in the fixing member rotating portion 4021, the convex portion of the first wave portion 4013 is used for limiting, so as to prevent the support plate 402 from rotating excessively.

[0114] In this embodiment, when the support plate 402 needs to rotate, push the support plate 402 to make the circular through portion 4022 thereof rotate a certain angle around the second circular boss 4011 at the bottom of the fixing member 401. At this time, the support plate 402 drives the rotating lock 403 and the second elastic member 404 in the first mounting position 4023 to rotate together. When the rotating lock 403 rotates to contact the convex portion of the first wave portion 4013, due to the obstruction of the convex portion, the rotating lock 403 cannot continue to rotate in the original direction. At this time, the second elastic member 404 is slightly compressed. As the support plate 402 continues to rotate, the rotating lock 403 will rotate to a position aligned with the recess of the first wave portion 4013. At this time, the rotating lock 403 is automatically snapped into the recess under the resilience of the second elastic member 404, realizing the locking of the support plate 402. Through the above steps, the effects of automatic locking and flexible adjustment are achieved.

[0115] A support plate moving position 5011 is provided at the top of the armrest seat 501; a long through hole 5012 is provided in the support plate moving position 5011; the long through hole 5012 is slidably connected to the first circular boss 3014; second wave portions 5013 are provided on both sides of the support plate moving position 5011; two symmetrically arranged second mounting positions 4025 are provided on the support plate 402; the two second mounting positions 4025 are connected; the translation assembly 5 further includes: a clamping member 502 provided in the second mounting position 4025 and a third elastic member 503 sleeved between the two clamping members 502; when the two clamping members 502 are adapted to move to the convex portions of the second wave portion 5013, the third elastic member 503 is compressed; and when the two clamping members 502 are adapted to move to the concave portions of the second wave portion 5013, the third elastic member 503 rebounds so that the two clamping members 502 contact the concave portions of the second wave portion 5013; the third elastic member 503 is preferably but not limited to a spring.

[0116] In this embodiment, the support plate 402 is placed in the support plate moving position 5011 of the armrest seat 501 and is slidably connected to the first circular boss 3014 through the long through hole 5012. The armrest seat 501 can be translated in the horizontal direction. When the armrest seat 501 is translated, the second wave portions 5013 on both sides of the armrest seat 501 interact with the two clamping members 502. When the clamping members 502 encounter the convex portions of the second wave portion 5013, they are blocked and the third elastic member 503 is compressed. As the armrest seat 501 continues to be translated, the concave portions of the second wave portion 5013 move to the positions aligned with the clamping members 502. At this time, the third elastic member 503 rebounds and pushes the clamping members 502 to be stuck into the concave portions of the second wave portion 5013, realizing the locking of the armrest seat 501. Applying a little external force to make the concave portions of the second wave portion 5013 disengage from the clamping members 502, the armrest seat 501 can continue to be translated to the next locking position. Through the above steps, the effect of automatic locking is achieved.

[0117] The translation assembly 5 further includes: an armrest housing 504 provided on the top of the armrest seat 501; the armrest seat 501 is snap-connected to the armrest housing 504; the armrest housing 504 is most preferably made of rubber material.
