Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat technology, and in particular to a seat armrest assembly and a seat. Background Technology
[0002] In related technologies, the armrest assembly of a seat includes a gravity locking hook hinged to the backrest frame, and a groove on the armrest frame connecting rod. During the process of the backrest frame flipping from the seat cushion to the sitting position, the gravity locking hook, due to its own weight, deflects at an angle towards the armrest frame connecting rod, causing its hook to engage in the groove on the armrest frame connecting rod. The armrest bracket, along with the backrest frame, flips together. When the armrest bracket, along with the backrest frame, flips to a vertical position, the gravity locking hook, due to its own weight, deflects away from the armrest frame connecting rod, causing its hook to disengage from the groove. When the backrest frame, carrying the armrest bracket, flips onto the seat cushion, the gravity locking hook, due to the squeezing action of the armrest frame connecting rod, disengages from the groove. However, existing seat armrest assemblies also have significant drawbacks: most existing seat armrest assemblies are one-piece structures with limited adjustment dimensions and adaptability to various scenarios.

[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0026] The following is for reference. Figures 1-4 The armrest assembly 1 of a seat according to an embodiment of the present utility model is described.
[0027] like Figures 1-3 As shown, the armrest assembly 1 of the seat according to an embodiment of the present invention includes: an armrest body 10, a connecting component 20, a folding component 30, and an armrest assembly 40. The armrest body 10 is the main part of the armrest 1 of the seat, mainly for the user's arm to rest on. The connecting component 20 mainly serves a connecting function, the folding component 30 mainly serves a folding function, and the armrest assembly 40 mainly provides support and comfort.
[0028] like Figure 1As shown, on the horizontal plane, the connecting component 20 is rotatably mounted on the handrail body 10, and on the vertical plane, the folding member 30 is rotatably mounted on the connecting component 20. On the horizontal plane, the connecting component 20 is connected to the handrail body 10, and the connecting component 20 can rotate, allowing relative movement between the connecting component 20 and the handrail body 10. On the vertical plane, the folding member 30 is connected to the connecting component 20, and the folding member 30 can rotate, allowing relative movement between the folding member 30 and the connecting component 20.
[0029] like Figure 1 and Figure 2 As shown, the handrail assembly 40 includes a first handrail 400 and a second handrail 401. On a horizontal plane, the first handrail 400 is movably disposed on the folding member 30, and the second handrail 401 is movably disposed on the connecting assembly 20. The first armrest 400 and the second armrest 401 are components of the armrest assembly 40, both providing support and comfort. On a horizontal plane, the first armrest 400 is movably mounted on the folding member 30, and the second armrest 401 is movably mounted on the connecting member 20. That is, on a horizontal plane, the first armrest 400 is connected to the folding member 30 and can move, allowing it to fold up and down. The second armrest 401 is connected to the connecting member 20 and can also move, enabling individual adjustment of the second armrest 401. The first armrest 400 and the second armrest 401 are connected through the connecting member 20 and the folding member 30, allowing for overall rotation of the first armrest 400 and the second armrest 401. In other words, the first armrest 400 and the second armrest 401 can both rotate as a whole and be adjusted individually, enhancing the overall seating experience.
[0030] Thus, on the horizontal plane, the first armrest 400 is movably mounted on the folding member 30, and the second armrest 401 is movably mounted on the connecting component 20. At this time, the first armrest 400 and the second armrest 401 can rotate as a whole or be adjusted individually, which can improve the overall experience of the seat.
[0031] Specifically, such as Figure 2 As shown, the armrest assembly 1 of the seat also includes: a first transmission assembly 50 and a second transmission assembly 60. The first transmission assembly 50 is movably disposed within the first armrest 400, and on the horizontal plane, the first transmission assembly 50 can rotate with the folding member 30. The second transmission assembly 60 is movably disposed within the second armrest 401, and on the horizontal plane, the second transmission assembly 60 can rotate with the connecting assembly 20.
[0032] Both the first transmission assembly 50 and the second transmission assembly 60 can perform transmission functions. The first transmission assembly 50 is movably disposed within the first armrest 400, which has an installation space. The first transmission assembly 50 is disposed within this installation space, thus making efficient use of the space occupied by the first armrest 400 and solving the space arrangement problem of the seat armrest assembly 1. The first transmission assembly 50 is movable relative to the first armrest 400. On a horizontal plane, the first transmission assembly 50 can rotate with the folding member 30. On a horizontal plane, the first armrest 400 achieves rotational engagement with the folding member 30 through the first transmission assembly 50, allowing the first armrest 400 to fold upwards or downwards. The second transmission assembly... The second transmission component 60 is movably disposed within the second armrest 401, which has an installation space. The second transmission component 60 is disposed within the installation space, which allows for efficient use of the space occupied by the second armrest 401 and reduces space occupancy. This solves the space arrangement problem of the armrest assembly 1 of the seat. The second transmission component 60 is movable relative to the second armrest 401. On the horizontal plane, the second transmission component 60 can rotate with the connecting component 20. On the horizontal plane, the second armrest 401 achieves rotational engagement with the connecting component 20 through the second transmission component 60. At this time, the first armrest 400 and the second armrest 401 are connected through the connecting component 20, enabling the overall rotation of the first armrest 400 and the second armrest 401.
[0033] Among them, such as Figure 2As shown, the first transmission assembly 50 includes a first slider 500 and a first locking member 501. The first locking member 501 is disposed on the first slider 500. The folding member 30 is provided with a first fixed shaft 300 and a second locking member 301. The first fixed shaft 300 extends into the first handrail 400, and the second locking member 301 is sleeved on the first fixed shaft 300. When the first handrail 400 rotates in the circumferential direction, the first locking member 501 selectively engages with the second locking member 301. The first slider 500 and the first snap-fit member 501 are components of the first transmission assembly 50. The first slider 500 mainly functions as a slider, while the first snap-fit member 501 functions as a snap-fit member, engaging with other components. The first snap-fit member 501 is mounted on the first slider 500, forming a single unit with the first slider 500, facilitating the installation and setup of the first transmission assembly 50. The folding member 30 is provided with a first fixed shaft 300 and a second snap-fit member 301. The first fixed shaft 300 functions as a fixing element, while the second snap-fit member 301 functions as a snap-fit member, engaging with other components. The first fixed shaft 300 extends into the first handrail 40. Within the first handrail 400, the first fixed shaft 300 is partially disposed inside the first handrail 400. The second snap-fit 301 is sleeved on the first fixed shaft 300 and connected to the first fixed shaft 300. At this time, the second snap-fit 301 and the first fixed shaft 300 form an integral whole. When the first handrail 400 rotates circumferentially, the first snap-fit 501 selectively engages with the second snap-fit 301. When the first handrail 400 rotates circumferentially, the first snap-fit 501 engages with the second snap-fit 301. This allows for rotational engagement between the first transmission assembly 50 and the folding member 30 on the horizontal plane, ensuring the stability of the first handrail 400.
[0034] The second transmission assembly 60 includes a second slider 600 and a third locking member 601. The third locking member 601 is disposed on the second slider 600. The connecting assembly 20 is provided with a second fixed shaft 200 and a fourth locking member 201. The second fixed shaft 200 extends into the second handrail 401, and the fourth locking member 201 is sleeved on the second fixed shaft 200. When the second handrail 401 rotates in the circumferential direction, the fourth locking member 201 selectively engages with the third locking member 601. The second slider 600 and the third locking member 601 are components of the second transmission assembly 60. The second slider 600 mainly functions as a slider, while the third locking member 601 functions as a locking element, engaging with other components. The third locking member 601 is mounted on the second slider 600, forming a single unit with it, facilitating the installation and setup of the second transmission assembly 60. The connecting assembly 20 is equipped with a second fixed shaft 200 and a fourth locking member 201. The second fixed shaft 200 functions as a fixing element, while the fourth locking member 201 engages with other components. The second fixed shaft 200 extends into the second handrail 40. Inside the second handrail 401, the second fixed shaft 200 is partially disposed inside the second handrail 401. The fourth snap-fit 201 is sleeved on the second fixed shaft 200 and connected to the second fixed shaft 200. At this time, the fourth snap-fit 201 and the second fixed shaft 200 form an integral whole. When the second handrail 401 rotates circumferentially, the fourth snap-fit 201 selectively engages with the third snap-fit 601. This allows for rotational engagement between the second transmission component 60 and the connecting component 20 on a horizontal plane, ensuring the stability of the second handrail 401.
[0035] In addition, such as Figure 2 As shown, the first latching member 501 is configured as a first latching protrusion, and the second latching member 301 has a plurality of spaced-apart first latching slots 302 in the circumferential direction. The first latching protrusion selectively engages with one of the plurality of first latching slots 302. By configuring the first latching member 501 as a latching protrusion and the second latching member 301 with a plurality of spaced-apart first latching slots 302 in the circumferential direction, the first latching slots 302 can engage with the first latching protrusion. The plurality of first latching slots 302 are spaced apart in the circumferential direction, which can avoid interference between the plurality of first latching slots 302 and at the same time make the distribution range of the first latching slots 302 wider. To a certain extent, it can also improve the engagement between the first latching member 501 and the second latching member 301. The first latching protrusion selectively engages with one of the plurality of first latching slots 302, thereby enabling the first latching member 501 to selectively engage with the second latching member 301.
[0036] The third latching member 601 is configured as a second latching protrusion, and the fourth latching member 201 has multiple spaced-apart second latching slots 205 in the circumferential direction. The second latching protrusion selectively engages with one of the multiple second latching slots 205. By configuring the third latching member 601 as a latching protrusion and the fourth latching member 201 with multiple spaced-apart second latching slots 205 in the circumferential direction, the second latching slots 205 can engage with the second latching protrusion. The multiple second latching slots 205 are spaced apart in the circumferential direction, which avoids interference between the multiple second latching slots 205 and allows for a wider distribution of the second latching slots 205. This also improves the engagement between the fourth latching member 201 and the third latching member 601 to a certain extent. The second latching protrusion selectively engages with one of the multiple second latching slots 205, thereby enabling the fourth latching member 201 to selectively engage with the third latching member 601.
[0037] Of course, such as Figure 2 The first transmission assembly 50 shown further includes: a fifth locking member 502, which is disposed on the first slider 500. The first handrail 400 includes: a first base 402, and a sixth locking member 403 is disposed on the inner side of the first base 402. The first slider 500 is slidably disposed in the sixth locking member 403 in the front-back direction. When the first handrail 400 moves in the front-back direction, the fifth locking member 502 selectively engages with the sixth locking member 403. The fifth locking member 502 serves a locking function and can engage with other components. The fifth locking member 502 is disposed on the first slider 500. The first armrest 400 includes a first base 402, which can fix the first armrest 400 to the seat or the seat frame. A sixth locking member 403 is disposed on the inner side of the first base 402. The sixth locking member 403 serves a locking function and can engage with other components. When the first armrest 400 moves in the front-back direction, the fifth locking member 502 selectively engages with the sixth locking member 403. When the first armrest 400 moves in the front-back direction, the fifth locking member 502 and the sixth locking member 403 engage. At this time, the first transmission component 50 and the first base 402 can be engaged, which can ensure the stability of the first armrest 400.
[0038] The second transmission assembly 60 further includes a seventh locking member 602, which is disposed on the second slider 600. The second handrail 401 includes a second base 404, and an eighth locking member 405 is disposed on the inner side of the second base 404. The second slider 600 is slidably disposed in the eighth locking member 405 in the front-back direction. When the second handrail 401 moves in the front-back direction, the seventh locking member 602 selectively engages with the eighth locking member 405. The seventh locking member 602 serves a locking function and can engage with other components. The seventh locking member 602 is disposed on the second slider 600. The second armrest 401 includes a second base 404, which can fix the second armrest 401 to the seat or the seat frame. An eighth locking member 405 is disposed on the inner side of the second base 404. The eighth locking member 405 serves a locking function and can engage with other components. When the second armrest 401 moves in the front-back direction, the seventh locking member 602 selectively engages with the eighth locking member 405. When the second armrest 401 moves in the front-back direction, the fifth locking member 502 engages with the sixth locking member 403. At this time, the second transmission component 60 and the second base 404 can be engaged, which can ensure the stability of the second armrest 401.
[0039] Furthermore, such as Figure 2 As shown, the fifth latching member 502 is configured as a third latching protrusion, and the sixth latching member 403 has multiple spaced third latching slots 406 in the front-back direction. The third latching protrusion selectively engages with one of the multiple third latching slots 406. By configuring the fifth latching member 502 as a latching protrusion and the sixth latching member 403 having multiple spaced third latching slots 406 in the front-back direction, the third latching slots 406 can engage with the third latching protrusion. The spaced arrangement of the multiple third latching slots 406 in the front-back direction avoids interference between the multiple third latching slots 406 and allows for a wider distribution of the third latching slots 406. This also improves the engagement between the fifth latching member 502 and the sixth latching member 403 to some extent. The selective engagement of the third latching protrusion with one of the multiple third latching slots 406 allows the fifth latching member 502 to selectively engage with the sixth latching member 403.
[0040] The seventh latching member 602 is configured as a fourth latching protrusion, and the eighth latching member 405 has multiple spaced fourth latching slots 407 in the front-back direction. The fourth latching protrusion selectively engages with one of the multiple fourth latching slots 407. By configuring the seventh latching member 602 as a latching protrusion and the eighth latching member 405 having multiple spaced fourth latching slots 407 in the front-back direction, the fourth latching slots 407 can engage with the fourth latching protrusion. The spaced arrangement of the multiple fourth latching slots 407 in the front-back direction avoids interference between the multiple fourth latching slots 407 and allows for a wider distribution of the fourth latching slots 407. This also improves the engagement between the seventh latching member 602 and the eighth latching member 405 to some extent. The selective engagement of the fourth latching protrusion with one of the multiple fourth latching slots 407 allows the seventh latching member 602 to selectively engage with the eighth latching member 405.
[0041] In addition, such as Figure 2 As shown, the first transmission assembly 50 further includes: a first elastic member 503 and a second elastic member 504. The first elastic member 503 abuts between the first snap-fit member 501 and the first slider 500, and the second elastic member 504 abuts between the fifth snap-fit member 502 and the first slider 500. It should be noted that both the first elastic element 503 and the second elastic element 504 can provide elastic force, playing a role in elastic adjustment. The first elastic element 503 abuts between the first locking element 501 and the first slider 500, with both ends of the first elastic element 503 abutting against the first locking element 501 and the first slider 500 respectively. This allows the first locking element 501 to selectively engage with the second locking element 301 when the first handrail 400 rotates circumferentially. The second elastic element 504 abuts between the fifth locking element 502 and the first slider 500, with both ends of the second elastic element 504 abutting against the fifth locking element 502 and the first slider 500 respectively. This allows the fifth locking element 502 to selectively engage with the sixth locking element 403 when the first handrail 400 moves in the back-and-forth direction. Both the first elastic element 503 and the second elastic element 504 can be springs; the number of first elastic elements 503 can be one, and the number of second elastic elements 504 can be two.
[0042] The second transmission assembly 60 further includes a third elastic member 603 and a fourth elastic member 604. The third elastic member 603 abuts between the third latching member 601 and the second slider 600, and the fourth elastic member 604 abuts between the seventh latching member 602 and the second slider 600. It should be noted that both the third elastic element 603 and the fourth elastic element 604 can provide elastic force, playing a role in elastic adjustment. The third elastic element 603 abuts between the third locking element 601 and the second slider 600, with both ends of the third elastic element 603 abutting against the third locking element 601 and the second slider 600 respectively. This allows the fourth locking element 201 to selectively engage with the third locking element 601 when the second handrail 401 rotates circumferentially. The fourth elastic element 604 abuts between the seventh locking element 602 and the second slider 600, with both ends of the fourth elastic element 604 abutting against the seventh locking element 602 and the second slider 600 respectively. This allows the seventh locking element 602 to selectively engage with the eighth locking element 405 when the second handrail 401 moves forward and backward. Both the third elastic element 603 and the fourth elastic element 604 can be springs; the number of third elastic elements 603 can be set to one, and the number of fourth elastic elements 604 can be set to two.
[0043] It should be noted that, as Figure 3 and Figure 4 As shown, the armrest assembly 1 of the seat also includes a control component 70, which is disposed within the folding member 30. The connecting component 20 is provided with a plurality of first limiting grooves 202, which are spaced apart circumferentially. The control component 70 includes a pressing member 700 and a locking member 701. The locking member 701 extends out of the folding member 30 and selectively engages with one of the plurality of first limiting grooves 202. After pressing the pressing member 700, the locking member 701 releases its engagement with the first limiting groove 202.
[0044] The control component 30 primarily functions as a control unit, used to adjust the position or height of the armrest assembly 40. The control component 70 is housed within the folding member 30, which has an internal installation space. This allows for efficient use of the space within the folding member 30, reducing space occupancy and thus resolving the space arrangement issue of the seat's armrest assembly 1. The connecting component 20 is equipped with multiple first limiting grooves 202, spaced circumferentially. These first limiting grooves 202 primarily function as limiting grooves in conjunction with other components. The multiple first limiting grooves 202 further enhance the adjustment options and stability of the armrest assembly 40, ensuring its adjustment support function. The circumferential spacing of the multiple first limiting grooves 202 prevents interference between them and allows for a wider distribution range. To a certain extent, this can also improve the adjustment options and stability of the armrest assembly 40. The control assembly 70 includes a pressing member 700 and a locking member 701. The pressing member 700 can be used to adjust the position of the armrest assembly 40, and the locking member 701 can fix the armrest assembly 40 in a specific position to ensure that it will not move accidentally. The locking member 701 extends outside the folding member 30, and the locking member 701 selectively engages with one of the multiple first limiting grooves 202. At this time, the user can adjust the height and angle of the armrest assembly 40 according to their needs. After pressing the pressing member 700, the locking member 701 releases its engagement with the first limiting groove 202. That is, when the user presses the pressing member 700, the pressing member 700 will apply pressure to the locking member 701, causing it to release from the current limiting groove. At this time, the armrest assembly 40 can be folded up or down by one hand, which can improve the overall experience of the seat.
[0045] In addition, such as Figure 1 As shown, both the connecting component 20 and the armrest assembly 40 are made of plastic, or both are made of metal. Plastic structural components have advantages such as lightweight and ease of molding, while metal structural components have advantages such as high strength and wear resistance. By making both the connecting component 20 and the armrest assembly 40 one of plastic or metal, the connecting component 20 and the armrest assembly 40 are more in line with actual working conditions, and the advantages of both materials can be well utilized. This ensures both a comfortable operating experience for the user and the reliability and durability of the seat armrest assembly 1.
