[0059] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application with reference to the drawings in the embodiments of the present application. The following embodiments are used to explain the present application, but not to limit the scope of the present application.

[0060] In the embodiments of the present application, the terms "first", "second" are only used for descriptive purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0061] In addition, in the embodiments of the present application, the orientation terms such as "upper", "lower", "left" and "right" are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0062] In the embodiments of the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood in a broad sense, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0063] In the embodiments of the present application, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes the elements inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "including a…" does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0064] In the embodiments of the present application, the word "exemplary" or "for example" is used to mean serving as an example, instance, or illustration. Any embodiment or design described in the embodiments of the present application as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the word "exemplary" or "for example" is used to present concepts in a concrete manner.

[0065] The embodiments of the present application provide a seat and a vehicle, which can avoid the seat from occupying the foot space of the passenger behind the seat, and improve the riding experience of the passenger behind the seat.

[0066] The seat in the related art includes a track and a framework, the track is arranged on the ground of the passenger cabin, the framework is located above the track, and the framework is connected to the track through an adjusting mechanism. In this way, a certain space is formed between the framework and the ground in the height direction. When the passenger sits in the rear row of the passenger cabin, the feet of the passenger in the rear row can extend into the space, which can improve the riding comfort of the passenger in the rear row to a certain extent.

[0067] However, since the connecting rod in the adjusting mechanism is arranged at the rear end of the framework, the framework will occupy the space. Especially when the passenger adjusts the height of the seat, the connecting rod will rotate and move in the height direction with the framework. When the connecting rod moves towards the ground, the feet of the passenger behind the seat will be pressed by the connecting rod, or the feet of the passenger behind the seat cannot extend into the space, thereby reducing the utilization rate of the space behind the seat and affecting the riding experience of the passenger behind the seat.

[0068] The seat and the vehicle provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0069] With reference to Figure 1 , Figure 2 and Figure 3 , the embodiments of the present application provide a seat, which can include a track assembly 100, a main body 200, a front connecting rod assembly 300, and a driving assembly 400.

[0070] If the seat is a seat in the passenger cabin of a vehicle, the track assembly 100 can be mounted on the ground in the passenger cabin. The seat can be used in the front row of the passenger cabin and the rear row of the passenger cabin. Hereinafter, the seat applied to the front row of the passenger cabin will be described as an example.

[0071] The main body 200 can be arranged in the height direction with the track assembly 100. The main body 200 can include a front end 210 and a rear end 220 opposite to each other in a first direction (such as the X direction in the figure). Figure 1 Figure 1 ​The second direction is perpendicular to the first direction.

[0072] In some examples, the main body 200 can include a seat skeleton, the front linkage assembly 300 and the driving assembly 400 can be connected to the seat skeleton, and the seat skeleton can be connected to the track assembly 100.

[0073] The front linkage assembly 300 is connected to the front end 210 at one end and rotatably connected to the track assembly 100 at the other end, and the front linkage assembly 300 is used to link the first side plate 230 and the second side plate 240.

[0074] It can be understood that if the seat is used in the passenger cabin of a vehicle, the first direction can be the length direction from the head of the vehicle to the tail of the vehicle, the front end 210 of the main body 200 is close to the head of the vehicle relative to the rear end 220, and the second direction can be the width direction of the vehicle.

[0075] In some embodiments, the track assembly 100 can include two tracks, the two tracks are arranged at intervals along the second direction (e.g. Figure 1 The first side plate 230 is rotatably connected to one of the two tracks through the front linkage assembly 300, and the second side plate 240 is rotatably connected to the other track through the front linkage assembly 300, so that the main body 200 is rotatably connected to the track assembly 100 through the front linkage assembly 300, and the main body 200 can move in the height direction (e.g. Figure 1 The height direction can be the height direction of the vehicle.

[0076] In addition, by using two tracks to connect the first side plate 230 and the second side plate 240 respectively, the stability of the main body 200 during movement relative to the track assembly 100 can be improved, and the movement stability during height adjustment of the seat can be improved.

[0077] One end of the driving assembly 400 is connected to the main body 200, and the other end is connected to the front linkage assembly 300, and the driving assembly 400 drives the front linkage assembly 300 to rotate relative to the track assembly 100 to adjust the height of the main body 200.

[0078] In some examples, the driving assembly 400 can be arranged close to the front linkage assembly 300 or close to the front end 210 of the main body 200, so as to avoid the problem that the driving assembly 400 occupies too much foot space of the passenger behind the seat due to being too close to the rear end 220 of the main body 200.

[0079] The embodiment of the present application provides a seat and a vehicle, the seat comprises a track assembly 100, a main body 200, a front connecting rod assembly 300, a driving assembly 400 and a first cross rod 500, one end of the front connecting rod assembly 300 is rotationally connected to the front end 210 of the main body 200, the other end of the front connecting rod assembly 300 is rotationally connected to the track assembly 100, the main body 200 can be relatively rotated with the track assembly 100 through the front connecting rod assembly 300, the front connecting rod assembly 300 can also be used to link the first side plate 230 and the second side plate 240, one end of the driving assembly 400 is connected to the main body 200, and the other end of the driving assembly 400 is connected to the front connecting rod assembly 300, so that the front connecting rod assembly 300 drives the first side plate 230 and the second side plate 240 to move in the height direction relative to the track assembly 100 under the driving of the driving assembly 400, the height adjustment of the main body 200 can be realized through the driving assembly 400 and the front connecting rod sub-assembly, and the height adjustment of the seat is realized, and the comfort of riding is improved.

[0080] In this way, the front connecting rod assembly 300 is arranged at the front end 210 of the main body 200 instead of the rear end 220 of the main body 200 in the prior art, and the driving assembly 400 arranged at the front end 210 drives the front connecting rod assembly 300 to drive the first side plate 230 and the second side plate 240 to move in the height direction, so that the connecting rod mechanism occupies the space between the main body 200 and the track assembly 100 in the height direction when the connecting rod mechanism is arranged at the rear end 220 of the main body 200, and the connecting rod mechanism is prevented from extending into the space between the frame and the ground for the feet of the passenger behind the seat, the space occupation of the seat is reduced, and the riding experience of the passenger in the vehicle is improved.

[0081] In some embodiments of the present application, referring to Figure 3 and Figure 4 The seat can further comprise the first cross rod 500 fixed to the rear end 220 of the main body 200, and the first cross rod 500 is used for fixing and connecting the first side plate 230 and the second side plate 240. In some examples, the first cross rod 500 is fixedly connected with the first side plate 230 and the second side plate 240 respectively, and the first cross rod 500 is fixed relative to the first side plate 230 and the second side plate 240.

[0082] By arranging the first horizontal rod 500 at the rear end 220 of the main body 200, the first horizontal rod 500 is arranged between the first side plate 230 and the second side plate 240, so that one end of the first horizontal rod 500 is fixedly connected to the first side plate 230, and the other end of the first horizontal rod 500 is fixedly connected to the second side plate 240. Thus, the first side plate 230 and the second side plate 240 can be connected by the first horizontal rod 500, and the connection stability between the first side plate 230 and the second side plate 240 can be improved.

[0083] In some examples, the first horizontal rod 500 can be arranged close to the first side plate 230 and the second side plate 240 and away from the side of the rail assembly 100, so that the first horizontal rod 500 is away from the ground. In this way, the foot space of the rear seat occupant can be avoided, and the space utilization of the rear seat occupant compartment can be further improved.

[0084] In some embodiments of the present application, with reference to Figure 3 and Figure 4 , the first horizontal rod 500 can be a cylindrical rod structure, and the first horizontal rod 500 has a bending portion 510 bent away from the rail assembly 100.

[0085] In this way, in the case that the first horizontal rod 500 is fixed relative to the first side plate 230 and the second side plate 240 and cannot rotate around the axis of the first horizontal rod 500, by arranging the bending portion 510 on the first horizontal rod 500 and bending the bending portion 510 away from the rail assembly 100, the bending portion 510 can be further away from the ground relative to other positions on the first horizontal rod 500, and a larger space can be provided between the bending portion and the ground. Thus, the foot space of the rear seat occupant can be further expanded, the riding comfort of the occupant can be improved, and the space utilization can be further improved.

[0086] In some embodiments of the present application, with reference to Figure 5 , the first horizontal rod 500 is a rib plate, one end of the rib plate is connected to the side of the first side plate 230 away from the rail assembly 100, and the other end of the rib plate is connected to the side of the second side plate 240 away from the rail assembly 100.

[0087] In some examples, the first horizontal rod 500 can also be a rib plate, and the thickness of the rib plate relative to the cylindrical rod structure is further reduced. Thus, on the basis of ensuring the connection stability of the first horizontal rod 500 between the first side plate 230 and the second side plate 240, the influence of the first horizontal rod 500 on the foot space can be further reduced, the space occupancy of the seat can be further reduced, the foot space of the rear seat occupant can be improved, and the riding experience of the occupant can be improved.

[0088] In some embodiments of the present application, with reference toFigure 5 The muscle plate has a bending portion 510 which is bent away from the track assembly 100.

[0089] In this way, by arranging the bending portion 510 on the muscle plate, the bending portion 510 can be further away from the ground relative to other positions on the muscle plate, and the bending portion 510 can correspond to the foot area of the passenger behind the seat, so as to further improve the accommodation space of the feet of the passenger behind the seat and improve the riding comfort of the passenger behind the seat.

[0090] In some embodiments of the present application, referring to Figure 1 and Figure 3 The seat can further include a support 600, one end of the support 600 being rotatably connected to the track assembly 100, and the other end being rotatably connected to the first cross bar 500. The support 600 is driven by the main body 200 and the first cross bar 500 to rotate relative to the first cross bar 500 and the track assembly 100.

[0091] In some examples, the drive assembly 400 drives the main body 200 to move in the height direction by driving the front linkage assembly 300, and the main body 200 drives the support 600 to rotate relative to the track assembly 100 during the movement. In this way, the support 600 can support the main body 200 during the movement of the main body 200, thereby improving the stability of the main body 200 during the movement.

[0092] In some examples, if the track assembly 100 has two tracks, and the two tracks are arranged corresponding to the first side plate 230 and the second side plate 240 respectively, the support 600 can also have two supports, one end of one support 600 being connected to the first side plate 230, and the other end being rotatably connected to one of the tracks, and one end of the other support 600 being connected to the second side plate 240, and the other end being rotatably connected to the other track. By arranging two supports 600, the stability of the main body 200 during the movement can be further improved.

[0093] In some examples, the support 600 can be rotatably connected to the first cross bar 500 to realize the rotatable connection of the support 600 to the first side plate 230 or the second side plate 240 of the main body 200.

[0094] In some embodiments of the present application, referring to Figure 4 and Figure 6 If the support 600 is rotatably connected to the first cross bar 500, the first cross bar 500 can include a limiting portion 520 arranged at the end of the first cross bar 500 and close to the first side plate 230.

[0095] The spacing is between the limiting portion 520 and the first side plate 230, one end of the support member 600 is sleeved on the end of the first cross bar 500 and located in the spacing between the first side plate 230 and the limiting portion 520.

[0096] In this way, by arranging the limiting portion 520 on the first cross bar 500 and sleeving one end of the support member 600 between the limiting portion 520 and the first side plate 230, the displacement of the end of the support member 600 connected with the first cross bar 500 in the length extension direction of the first cross bar 500 can be reduced, and the connection stability between the support member 600 and the first cross bar 500 can be improved.

[0097] In some embodiments, if the support member 600 has two, the two support members 600 are respectively connected to the two ends of the first cross bar 500 in the length direction, the limiting portion 520 can have two, one limiting portion 520 can be arranged on each end of the first cross bar 500 in the length direction, so that the displacement of the two support members 600 in the length direction of the first cross bar 500 is limited by arranging two limiting portions 520, and the stability of the main body portion 200 during the movement in the height direction is improved.

[0098] In some embodiments of the present application, referring to Figure 1 and Figure 7 , the front linkage assembly 300 can include a first connecting member 310, a second connecting member 320 and a second cross bar 330.

[0099] One end of the first connecting member 310 is rotationally connected with the track assembly 100, and the other end of the first connecting member 310 is rotationally connected with the first side plate 230. One end of the second connecting member 320 is rotationally connected with the track assembly 100, and the other end of the second connecting member 320 is rotationally connected with the second side plate 240. One end of the second cross bar 330 is connected with the first connecting member 310, and the other end is connected with the second connecting member 320. The first connecting member 310 is used to jointly adjust the height of the main body portion 200 by driving the second connecting member 320 through the second cross bar 330 under the driving of the driving assembly 400.

[0100] In this way, by using the first cross bar 500 to transmissionally connect the first connecting member 310 and the second connecting member 320, when the driving assembly 400 drives the first connecting member 310, the second connecting member 320 can be driven through the second cross bar 330, so that the first side plate 230 and the second side plate 240 of the main body portion 200 can be synchronously driven through the front linkage assembly 300 to realize the adjustment of the main body portion 200 in the height direction, which can also avoid the imbalance of the main body portion 200 during the movement caused by driving only the first side plate 230 or the second side plate 240, improve the stability of the main body portion 200 during the movement, and avoid the problem of side inclination of the seat during the movement.

[0101] In some examples, if the track assembly 100 includes two tracks, one end of the first connecting member 310 away from the first side plate 230 can be rotatably connected to one of the tracks, and one end of the second connecting member 320 away from the second side plate 240 can be rotatably connected to the other track.

[0104] In this way, the driving motor 410 is used to drive the lead screw 420 to rotate, so as to drive the shaft sleeve 430 to move along the axial direction of the lead screw 420 relative to the lead screw 420, and since one end of the lead screw 420 is rotatably connected to the main body 200 and the shaft sleeve 430 is rotatably connected to the front connecting rod assembly 300, the driving motor 410 can drive the front connecting rod assembly 300 to rotate around the connection between the shaft sleeve 430 and the front connecting rod assembly 300, and the front connecting rod assembly 300 can drive the main body 200 to adjust in the height direction.
