The present application proposes a seat which may be a seat applied to a vehicle, as described hereinafter, wherein the vehicle may be a vehicle or an aircraft or the like. Of course, the seat may be a home seat or an office seat. It will be seen that the application is not limited in terms of the type of seat.

Next, the structure of the seat according to the present application will be explained and illustrated with reference to fig. 1 to 5, and in an embodiment of the present application, the seat 100 according to the present application includes a seat body 10, an armrest 20, and a first driving mechanism 30; the first driving mechanism 30 is arranged on the seat body 10, the first driving mechanism 30 comprises a first driving piece 31 and a first transmission assembly 32, and the first transmission assembly 32 is in transmission connection with the first driving piece 31 and the armrest 20; the first driving member 31 is configured to move the handrail 20 at least in a first direction and a second direction, which are different from each other, by means of the first transmission assembly 32.

The seat body 10 may include a support portion 11 and a backrest portion 12 disposed at an included angle. At this time, the occupant can sit on the support portion 11, and the occupant can lean on the backrest portion 12, thereby improving the riding comfort. The supporting portion 11 may be a plate structure, a seat structure, a frame structure formed by combining a plurality of columns, or the like, and the application is not limited to the type and shape of the supporting portion 11. Similarly, the backrest 12 may be a plate structure, a seat structure, a frame structure formed by combining a plurality of columns, or the like, and the application is not limited to the type and shape of the backrest 12.

The number of armrests 20 may be two and are respectively mounted on opposite sides of the backrest 12 of the seat body 10. The two armrests 20 and the support portion 11 may be disposed to extend toward the same side of the backrest portion 12 so that the armrests 20 are placed by the hands of an occupant seated on the seat body 10. The armrest 20 may have a cylindrical structure, or may have a plate structure, or the like, and the present application is not limited to the type and shape of the armrest 20.

The first driving mechanisms 30 may be provided in number corresponding to the handrails 20 so as to drive the corresponding handrails 20 to move. Specifically, the first driving member 31 of the first driving mechanism 30 may be configured to provide power, and the first transmission assembly 32 may be configured to transmit the power to the handrail 20, thereby moving the handrail 20 in at least a first direction and a second direction. The first driving mechanism 30 may only drive the handrail 20 to move in the first direction and the second direction, or may further move in a third direction as described below on the basis of the first driving mechanism, so as to ensure that the first driving mechanism 30 can drive the handrail 20 to move in at least two directions. In addition, the first driving mechanism 30 may drive the handrail 20 to move in the first direction and the second direction in the same or different types, and the movement type may be sliding or rotating. Thus, when the first driving mechanism 30 moves the armrest 20 in the sliding motion in both the first direction and the second direction, the first direction and the second direction may intersect. The first direction may be a horizontal direction (with reference to the seat 100 in a normal use state), and may be an up-down direction. At this time, when the first direction is the horizontal direction, the width between the armrests 20 can be adjusted by sliding the armrests 20 in the first direction, and the height of the armrests 20 can be adjusted by sliding the armrests in the second direction. when the first direction is the up-down direction, the height position of the armrest 20 can be adjusted by sliding the armrest 20 in the first direction, and the width between the armrests 20 can be adjusted by sliding the armrest 20 in the second direction. Of course, the second direction may be looped around the first direction as described below when the first drive mechanism 30 moves the armrest 20 in a sliding motion in the first direction and in a rotating motion in the second direction. At this time, when the first direction is the horizontal direction, the handrail 20 slides in the first direction to adjust the width between the two handrails 20, and the rotation in the second direction can adjust the included angle between the handrail 20 and the horizontal plane. when the first direction is the up-down direction, the armrest 20 slides in the first direction to adjust the height position of the armrest 20, and the rotation in the second direction can adjust the included angle between the armrest 20 and the vertical plane. Alternatively, the first driving mechanism 30 may drive the handrail 20 to rotate in both the first direction and the second direction. At this time, the rotation in the first direction and the second direction can achieve adjustment of the angle between the armrest 20 and the horizontal and vertical planes. It can be seen that the present application is not limited to the type of movement of the first drive mechanism 30 to drive the handrail 20 in the first and second directions. In addition, the first driving mechanism 30 may simultaneously drive the handrail 20 to perform the synchronous movement in the first direction and the second direction. Of course, the first driving mechanism 30 may separately drive the handrail 20 to move independently in the first direction and the second direction. The first driver 31 of the first driving mechanism 30 may be a rotary motor, or may be a rotary cylinder. While the first driving member 31 drives the handrail 20 to slide along the first direction and rotate along the second direction through the first transmission assembly 32, the first transmission assembly 32 can be used with the movement switching assembly 40 and the first screw rod 321 as described below. of course, a gear set may be further included on the basis of the first screw 321. At this time, the first screw rod 321 may drive the base body for mounting the armrest 20 to slide in the first direction, and the power on the first driving member 31 may be transferred to the rotation shaft spaced parallel to the rotation axis of the first driving member 31 through the gear set, where the rotation shaft may be slidably inserted and engaged with the rotation shaft of the armrest 20 mounted on the base body in the first direction, so as to satisfy that the mounting seat and the armrest 20 may slide in the first direction, and meanwhile, the rotation shaft may drive the armrest 20 to rotate in the second direction. when the first driving member 31 drives the handrail 20 to slide along the first direction and slide along the second direction through the first transmission assembly 32, the first transmission assembly 32 may include a first screw rod 321, a telescopic assembly and a gear set. At this time, the first screw 321 overlapping with the rotation axis of the first driving member 31 can drive the fixing portion of the telescopic assembly capable of telescoping in the second direction to slide in the first direction, and the armrest 20 can be fixed to the telescopic portion of the telescopic assembly. The power on the first driving member 31 may be further transmitted to another first screw rod 321 intersecting with the rotation axis of the first driving member 31 through a gear set, where the first screw rod 321 may drive a fixing portion of a telescopic assembly capable of stretching along the first direction to slide along the second direction, and a telescopic portion of the telescopic assembly is connected to a telescopic portion capable of stretching along the second direction. it will be appreciated that the present application is not limited in terms of the type of construction of the first transmission assembly 32.

When the seat 100 of the technical scheme of the application is used, the first driving mechanism 30 can drive the armrest 20 to move, so that the position of the armrest 20 is adjusted in a moving way, the armrest 20 can be conveniently matched with the body of a passenger for use, and the use experience of the passenger on the seat 100 is improved. Moreover, the first driving mechanism 30 in this embodiment further includes a first driving member 31 and a first transmission assembly 32, where the first driving member 31 can drive the handrail 20 to move at least along different first and second directions through the first transmission assembly 32. At this time, the position of the armrest 20 can be moved and adjusted in at least two directions, so that the diversity of the position adjustment of the armrest 20 can be enriched, and the armrest 20 is more suitable for the body (such as height or fat and thin) of the occupant, thereby further improving the use experience of the occupant on the seat 100. At the same time, the first driving member 31 is also shared during the adjustment of the position of the armrest 20 in at least two directions. At this time, the number of the first driving members 31 is simplified, thereby contributing to a reduction in the manufacturing cost of the seat 100. Meanwhile, since the simplification of the number of the first driving members 31 also reduces the entire volume of the first driving mechanism 30, it is advantageous to improve the convenience of the subsequent installation and arrangement of the first driving mechanism 30 in a limited space on the seat 100.

Referring to fig. 3 to 5 in combination, in an embodiment of the application, the first driving member 31 drives the handrail 20 to slide along a first direction and rotate along a second direction through the first transmission assembly 32, and the second direction surrounds the first direction.

The first direction may be a horizontal direction when the seat 100 is in a normal use state, and may be an up-down direction.

In this embodiment, the first driving member 31 is configured to drive the handrail 20 to slide and rotate through the first transmission assembly 32, so that the first driving mechanism 30 drives the handrail 20 to move in the first direction and the second direction in a more compact relationship, and further it is convenient to realize that the first driving mechanism 30 drives the handrail 20 to perform the two movements. At this time, the structure of the first transmission assembly 32 in the first driving mechanism 30 may be simplified to improve the convenience of manufacturing the seat 100. At the same time, the overall volume of the first transmission assembly 32 is reduced to further enhance the ease of mounting and arranging the first drive mechanism 30 within the limited space on the seat 100.

Referring to fig. 3 to 5 in combination, in an embodiment of the application, the first transmission assembly 32 includes a first screw rod 321, and the first screw rod 321 is disposed along a first direction and connected to the first driving member 31; the armrest 20 is provided with a first threaded hole 21, and one end of the first screw rod 321 far away from the first driving piece 31 is in threaded connection with the first threaded hole 21; the seat 100 further includes a movement switching assembly 40, the movement switching assembly 40 having a first state in which the movement switching assembly 40 performs a limit lock on the rotation of the armrest 20 and a second state in which the movement switching assembly 40 releases the limit lock on the armrest 20.

The first screw 321 may be driven to rotate by the first driving member 31. The first threaded hole 21 may be used for threaded engagement with the first screw 321. Wherein the first threaded hole 21 may be provided directly on the armrest 20. Of course, the armrest 20 may be connected to a slide, and the first screw hole 21 may be provided in the slide. The motion switching assembly 40 may be used to switch the type of movement of the first drive mechanism 30 to drive the handrail 20. Specifically, when the motion switch assembly 40 is in the first state, the armrest 20 is restrained in the second direction by the restraint lock on the rotation of the armrest 20. At this time, the armrest 20 cannot rotate relative to the first screw 321, and further, the armrest 20 can only slide in the first direction when the first screw 321 rotates. When the motion switch assembly 40 is in the second state, the limit of the armrest 20 in the second direction is released due to the motion switch assembly 40 releasing the limit lock on the armrest 20. At this time, the armrest 20 may rotate relative to the first screw 321, and when the first screw 321 rotates, the armrest 20 may rotate along the second direction along with the first screw 321. The motion switching assembly 40 may include a fixed member 41 and a movable member 42 as described below. Of course, the motion switch assembly 40 may also include a deformable elastic rotation stopping member, and the elastic rotation stopping member is driven to elastically deform to perform abutting rotation stopping on the armrest 20. Alternatively, the motion switch assembly 40 may include two clamps that are urged toward and thereby hold the handrail 20 against rotation. It can be seen that the application is not limited to the type of construction of the motion switch assembly 40.

In this embodiment, the first transmission assembly 32 is configured to include the first screw rod 321, so that the first transmission assembly can better receive the driving of the first driving member 31, and meanwhile, the first transmission assembly is convenient to connect with the threaded hole, and after being matched with the motion switching assembly 40, the handrail 20 can be driven to slide in the first direction and rotate in the second direction independently. And the first screw rod 321 also has a self-locking function after rotating, so that the armrest 20 is regulated and stably limited, and a limiting structure for the armrest 20 after regulating in place is not required to be additionally arranged. Therefore, the number of parts of the first transmission assembly 32 at this time is small, and the structure of the first transmission assembly 32 can be further simplified to improve the convenience of manufacturing the first driving mechanism 30. At the same time, the overall volume of the first drive mechanism 30 can be further reduced to further improve the convenience of installation and arrangement thereof in a limited space on the seat 100. In addition, the sliding of the armrest 20 in the first direction and the rotation of the armrest 20 in the second direction are performed separately and independently, so that the armrest 20 can be adjusted more flexibly, and the body-fitting effect on the passengers can be further improved.

Referring to fig. 4 to 8 in combination, in an embodiment of the present application, the motion switching assembly 40 includes a fixed member 41 and a movable member 42, wherein one of the fixed member 41 and the movable member 42 is disposed on the seat body 10, and the other of the fixed member 41 and the movable member 42 is movably disposed on the armrest 20; in the first state, the movable member 42 and the fixed member 41 are abutted, and in the second state, the movable member 42 and the fixed member 41 are separated.

The fixing member 41 may be fixedly provided on the seat body 10, or may be fixedly provided on the armrest 20. The fixing member 41 may be a column structure, a plate structure, a seat structure, or the like, and the application is not limited to the structure type and shape of the fixing member 41. The movable member 42 may be movably mounted on the seat body 10, or may be movably mounted on the armrest 20, so as to be able to be disposed on the seat body 10 and the armrest 20 separately from the fixed member 41. The movable member 42 may be a column structure, a plate structure, a seat structure, or the like, and the application is not limited to the type and shape of the movable member 42. The movable member 42 may be slidably mounted or rotatably mounted, and the manner of mounting the movable member 42 is not limited in the present application. In addition, in the first state, the movable member 42 and the fixed member 41 are abutted. At this time, the abutting manner includes abutting of the movable member 42 and the fixed member 41 to play a role in stopping rotation of the armrest 20 by friction between the movable member 42 and the fixed member 41. Of course, the abutting manner may also include that the movable member 42 and the fixed member 41 are detachably connected by magnetic connection or snap connection, so as to play a role in stopping rotation of the handrail 20 by the connection force between the movable member 42 and the fixed member 41. It can be seen that the present application is not limited to the manner of abutting the movable member 42 and the fixed member 41.

In this embodiment, the motion switching assembly 40 is configured to include the fixed member 41 and the movable member 42, and the rotation stopping of the armrest 20 is indirectly achieved by the contact between the movable member 42 and the fixed member 41, so that the motion switching assembly 40 does not need to directly stop the rotation of the armrest 20, and further, the structure of the motion switching assembly 40 is simplified and the size of the motion switching assembly is reduced, so that the convenience of installation and arrangement of the motion switching assembly on the seat 100 is further improved.

Referring to fig. 4 and 5 in combination, in an embodiment of the application, the fixing member 41 is disposed on the seat body 10, and the movable member 42 is disposed on the armrest 20.

In this embodiment, the armrest 20 is relatively small and is relatively close to the hands of the occupant, so that the occupant can operate the movable member 42 conveniently, and the occupant can experience the seat 100 more conveniently.

In an embodiment of the present application, the movable member 42 includes a sliding portion 421 and an abutting portion 422, where the sliding portion 421 is disposed along a first direction and is slidably disposed on the seat body 10 or the armrest 20; the abutting portion 422 is connected to the sliding portion 421, the abutting portion 422 extends to an arc structure along the second direction, and the axis of the abutting portion 422 coincides with the axis of the first screw 321; in the first state, the abutting portion 422 abuts against the fixing member 41, and in the second state, the abutting portion 422 is separated from the fixing member 41.

The sliding portion 421 may be slidably mounted on the seat body 10 or the armrest 20. The sliding portion 421 may have a cylindrical structure or a plate structure, and the present application is not limited to the type and shape of the sliding portion 421. The docking portion 422 may be connected to one end of the sliding portion 421 for docking with the fixed portion. The abutting portion 422 may be an arc-shaped plate structure or an arc-shaped base structure, and the application is not limited to the type of the abutting portion 422.

In the present embodiment, the movable member 42 is provided to include the sliding portion 421 and the abutting portion 422, so that the movable member 42 can be slidably mounted and abutted with the fixed member 41 by the sliding portion 421 and the abutting portion 422, respectively. That is, by using different functions at different portions of the movable member 42, the occurrence of interference effects is reduced, and the convenience of mounting the movable member 42 and docking with the fixed member 41 is improved. Meanwhile, since the abutting portion 422 has an arc structure, after the armrest 20 is rotated and adjusted to enable the movable member 42 to rotate along with the armrest 20, the abutting portion 422 can still effectively contact and limit the fixed member 41 after the movable member 42 is reset.
