Description

Technical Field

[0001] This application relates to the field of seating technology, and more particularly to a seat, control method, control module, cockpit, and vehicle. Background Technology

[0002] With the continuous development of technology, the interior space of family cars has gradually acquired more functions, and family cars need to meet the needs of more usage scenarios, such as office, entertainment, and rest.

[0003] In existing technologies, the rear seats of automobiles can be folded down or assembled to obtain a longer length and a larger area, forming a "bed"-like structure, thus facilitating users to lie down and rest.

[0004] However, there is still room for improvement in the length of the seat when it is folded down in the existing technology. Summary of the Invention

[0005] The purpose of this application is to provide a seat, a control method, a control module, a cockpit, and a vehicle.

[0006] In a first aspect, this application provides a seat, including a base, a seat cushion, a first backrest, and a second backrest. The seat cushion has a first end and a second end opposite to each other, the seat cushion is slidably connected to the base, and the first end of the seat cushion is rotatable relative to the base. The first backrest has a first end and a second end opposite to each other, and the first end of the first backrest is rotatably connected to the base. The second backrest has a first end and a second end opposite to each other, and the first end of the second backrest is rotatably connected to the base. The seat has a sitting state and a reclining state. When the seat is in the sitting state, the first end of the seat cushion is away from the first backrest relative to the second end of the seat cushion, and the second end of the seat cushion is abutted against the first end of the first backrest. An angle is formed between the seat cushion and the first backrest, forming a sitting space. The second backrest is located on the side of the first backrest facing away from the sitting space and is abutted against the first backrest. The seat cushion is used to move forward and flip forward relative to the base, the first backrest is used to flip forward relative to the base to unfold, and the second backrest is used to flip backward relative to the base to unfold, so that the seat can switch from the sitting state to the reclining state.

[0007] In this embodiment, the seat cushion flattens itself by combining forward movement and forward flipping, making room for the first backrest to flatten. This movement of the seat cushion allows for sufficient space for the first backrest, which is beneficial for setting the dimensions of the seat cushion and the first backrest reasonably, taking into account the appropriate dimensions of the seat in both sitting and reclining states. On the other hand, the appropriate movement distance of the seat cushion facilitates the simplification of the sliding and rotating connection structures between the seat cushion and the base, and ensures sufficient support for the seat cushion, making the manufacture of the seat easier.

[0008] When the seat switches from a sitting position to a reclining position, the seat cushion flips forward to utilize the space in front of the seat, and the second backrest flips backward to utilize the space behind the seat. This allows the seat to achieve its maximum length in the reclining position through structural deformation alone, without the need for external structures, to accommodate users of different heights. Furthermore, the forward-flipping movement of the first backrest keeps the seat's center position essentially unchanged, ensuring a suitable seating position in both sitting and reclining positions. This eliminates the need for excessive additional space in the reclining position, thereby improving the seat's adaptability to vehicles of different sizes.

[0009] In some embodiments, when the seat is in a reclined position, the first backrest is located between the seat cushion and the second backrest, and the second end of the seat cushion, the first end of the seat cushion, the second end of the first backrest, the first end of the first backrest, the first end of the second backrest, and the second end of the second backrest are arranged sequentially in the direction from the seat cushion to the second backrest.

[0010] In this embodiment, the seat cushion, the first backrest, and the second backrest of the chair are in roughly the same posture, that is, all three are laid flat. The seat cushion, the first backrest, and the second backrest are arranged in sequence and can be combined to form a long support structure. Therefore, the chair is in the form of a "bed" and the user can lie down in the space on the top side of the seat cushion, the first backrest, and the second backrest. The seat cushion, the first backrest, and the second backrest together provide support for the user.

[0011] In some implementations, when the seat is in a reclined position, the first end of the seat cushion is joined to the second end of the first backrest, and / or, the first end of the first backrest is joined to the first end of the second backrest.

[0012] In this embodiment, the seat cushion and the first backrest, and the first backrest and the second backrest are spliced ​​together to form a large and complete support structure. This provides good support to the user directly without the need for additional support structures, resulting in a better user experience.

[0013] In some embodiments, the seat cushion has a first side and a second side facing away from each other, the first backrest has a third side and a fourth side facing away from each other, and the second backrest has a fifth side and a sixth side facing away from each other. When the seat is in a sitting position, the first side and the third side are joined together to form a sitting space, and the fourth side and the fifth side are arranged opposite each other. When the seat is in a reclining position, the second side, the fourth side, and the fifth side face the same side of the seat, and the fourth side is joined together with the second side and the fifth side to form a support surface for the seat.

[0014] In this embodiment, when the seat is in a seated position, the first and third surfaces are used to provide support for the user. The first and second surfaces can be designed with appropriate shapes to provide a more comfortable seating experience for the user.

[0015] The seat provides corresponding support through different surfaces when in the sitting and reclining positions, which allows for different surface shapes to meet different usage needs.

[0016] In some implementations, the second, fourth, and fifth surfaces are all planar and flush.

[0017] In this embodiment, when the seat is in a reclining state, the second, fourth, and fifth surfaces are used to provide support for the user. Since the second, fourth, and fifth surfaces are flat, the seat can provide a large and flat support surface, which is convenient for the user to lie down and helps to provide a comfortable reclining experience.

[0018] In some embodiments, in a direction parallel to the rotation axis of the first backrest and the base, the length of the first end of the seat cushion is greater than the length of the second end of the seat cushion, the length of the first end of the first backrest is less than the length of the second end of the first backrest, and the length of the first end of the second backrest is less than the length of the second end of the second backrest.

[0019] In this embodiment, when the seat is in the sitting position, the second end of the seat cushion, the first end of the first backrest, and the first end of the second backrest are close in position and all three are relatively short. The first end of the seat cushion and the second end of the first backrest are relatively long, which helps to provide more seating space when the seat is in the sitting position. When the seat is in the reclined position, the dimension at the joint between the first end of the first backrest and the first end of the second backrest is narrower, and the dimensions at the second ends of the first backrest and the second backrest are wider, which helps to maximize the load-bearing capacity of the seat in the reclined position.

[0020] In some embodiments, when the seat is in the third state, the seat cushion and the first backrest are laid flat, and the second backrest is erected; wherein, in the direction of the seat cushion pointing to the first backrest, the second end of the seat cushion, the first end of the seat cushion, the second end of the first backrest, and the first end of the first backrest are arranged in sequence, and the first backrest and the second backrest have an angle between them.

[0021] In this embodiment, the seat cushion and the first backrest can be laid flat to have a long bearing size and a large bearing area, and the second backrest can be erected to provide back support for the user. The seat can meet the user's needs for semi-reclining or other postures, thereby meeting the user's needs for movie watching, office work and other usage scenarios.

[0022] Furthermore, the second backrest can isolate the space in front of it from the space behind it, providing the seat with good privacy.

[0023] In some embodiments, the seat cushion is slidably connected to the base along a first direction, which is the arrangement direction of the seat cushion and the first backrest when the seat is in a reclining state; the seat cushion is rotatable about a first axis, which is perpendicular to the first direction.

[0024] In this embodiment, the direction of movement of the seat cushion is the same as the direction of arrangement of the seat cushion and the first backrest, which facilitates the rapid movement of the seat cushion so that the seat can be quickly unfolded and put into place, reducing the time for the seat to switch states.

[0025] In some embodiments, the seat further includes a first connecting assembly, which includes a slide rail and a bracket, the slide rail being slidably connected to the bracket, one of the slide rail and the bracket being fixedly connected to a base, and the other being rotatably connected to a seat cushion.

[0026] In this embodiment, the seat cushion and the base are slidably connected by a slide rail and a bracket, which facilitates the seat cushion to move in a straight line relative to the base. The slide rail and the bracket have a simple and reliable structure, strong load-bearing capacity, and are easy to manufacture.

[0027] In some embodiments, the bracket includes a sliding part, a support rod, and a connecting part. The support rod and the connecting part are both fixed to the sliding part. The sliding part is slidably connected to a slide rail, and the connecting part is rotatably connected to the seat cushion.

[0028] When the seat is in the seated position, the support rod is closer to the second end of the seat cushion than the first end of the seat cushion, so that the support rod supports the seat cushion.

[0029] In this embodiment, the support rod can provide good support for the seat cushion, so that the seat has good load-bearing capacity when in use.

[0030] In some embodiments, the first connecting assembly further includes a first power member and a first angle adjuster. The first power member is fixedly mounted on the seat cushion, the first angle adjuster is rotatably connected to the seat cushion and the bracket, and the first power member is drively connected to the first angle adjuster. The first power member is used to drive the seat cushion to rotate around a first axis.

[0031] In this embodiment, by setting a first power component and a first angle adjuster, the connection structure between the seat cushion and the bracket is simple, reliable, easy to manufacture, and has good load-bearing capacity.

[0032] In some embodiments, the seat further includes a second connecting assembly, which includes a second adjuster and a second power member. The second adjuster is rotatably connected to the first backrest and the base, and the second power member is drively connected to the second adjuster. The second power member is used to drive the first backrest to rotate.

[0033] In this embodiment, by setting a second angle adjuster and a second power component, the connection structure between the first backrest and the base is simple, reliable, easy to manufacture, and has good load-bearing capacity.

[0034] In some embodiments, the first end of the second backrest is rotatably connected to the first end of the first backrest.

[0035] In this embodiment, the first end of the second backrest is directly connected to the first end of the first backrest, and the two are close together. When the seat is in a sitting position, it is beneficial to make the first end of the second backrest and the first end of the first backrest close together, thereby reducing the space occupied by the second backrest. When the seat is in a reclining position, it is beneficial to make the first end of the second backrest and the first end of the first backrest seamlessly connected, thereby improving the comfort of seat support.

[0036] In some embodiments, the seat further includes a third connecting assembly, which includes a third power member and a transmission assembly. The third power member is fixed to the first backrest, and the transmission assembly drives the third power member and the second backrest to rotate.

[0037] In this embodiment, by setting a third connecting component, the second backrest is driven by another transmission component, making the position setting of the third power component more flexible and facilitating the concealed setting of the third connecting component.

[0038] In some embodiments, the seat also includes a headrest slidably connected to the first backrest; when the seat is in a seated position, the headrest extends relative to the first backrest, and when the seat is in a reclined position, the headrest retracts at least partially into the receiving space of the first backrest.

[0039] In this embodiment, when the seat is in the sitting position, the headrest can be positioned at a higher level to provide suitable support. When the seat is in the reclined position, the headrest does not occupy the space between the seat cushion and the first backrest, facilitating the connection between the seat cushion and the first backrest.

[0040] In some embodiments, the seat cushion includes a first frame and a first cushioning member, the first cushioning member being disposed outside the first frame; the first backrest includes a second frame and a second cushioning member, the second cushioning member being disposed outside the second housing; and the second backrest includes a third frame and a third cushioning member, the third cushioning member being disposed outside the third frame.

[0041] In this embodiment, the seat cushion, the first backrest, and the second backrest all have cushioning and support structures to meet the support requirements of the seat in both sitting and reclining states.

[0042] In some embodiments, during the process of switching the seat from a sitting state to a reclining state, the seat cushion is used to rotate around a first end of the seat cushion by a first angle, the first backrest is used to rotate around a first end of the first backrest towards the direction closer to the seat cushion by a second angle, and the second backrest is used to rotate around a first end of the second backrest towards the direction away from the first backrest by a third angle. The first angle is in the range of ° to °, the second angle is in the range of ° to °, and the third angle is in the range of ° to °.

[0043] In this embodiment, the entire seat cushion is flipped over, and the orientation of the two opposite sides of the seat cushion is reversed, so that the seat cushion can be roughly laid flat in both the sitting and lying-down states, and the seat cushion can also be relatively flat in the lying-down state, making it convenient to lie down.

[0044] The first backrest has been flipped over, changing from an upright position to a flat position. Therefore, the first backrest provides good support for the user's sitting posture when seated and is relatively flat when lying down, which facilitates support for the user's reclining posture.

[0045] The second backrest has been flipped up from an upright position to a flat position. This makes it easier for the second backrest to stand upright and rest against the first backrest when the seat is in a sitting position. The second backrest takes up less space and does not waste space. In addition, when the seat is in a reclining position, the second backrest is relatively flat, which is convenient for supporting the user's reclining posture.

[0046] In some embodiments, when the seat is in a reclined position, there is a first length between the second end of the seat cushion and the second end of the second backrest; wherein the first length is greater than or equal to 0.5 meters.

[0047] In this embodiment, the seat has a relatively long length, which can realize the "bed" form and meet the lying needs of most users.

[0048] Secondly, embodiments of this application provide a control method for controlling seat switching states.

[0049] The seat includes a base, a cushion, a first backrest, and a second backrest; the cushion has a first end and a second end opposite to each other, the cushion is slidably connected to the base, and the first end of the cushion is rotatable relative to the base; the first backrest has a first end and a second end opposite to each other, the first end of the first backrest is rotatably connected to the base; the second backrest has a first end and a second end opposite to each other, the first end of the second backrest is rotatably connected to the base.

[0050] The seat has a sitting position and a reclining position. When the seat is in the sitting position, the first end of the seat cushion is away from the first backrest relative to the second end of the seat cushion, and the second end of the seat cushion is against the first end of the first backrest. There is an angle between the seat cushion and the first backrest, forming a seating space. The second backrest is located on the side of the first backrest that faces away from the seating space, and the second backrest is against the first backrest.

[0051] Control methods include: Control the seat cushion to move forward relative to the base; control the seat cushion to flip forward relative to the base; control the first backrest to flip forward relative to the base; control the second backrest to flip backward relative to the base.

[0052] In this embodiment, the seat cushion flattens itself by combining forward movement and forward flipping, making room for the first backrest to flatten. This movement of the seat cushion allows for sufficient space for the first backrest, which is beneficial for setting the dimensions of the seat cushion and the first backrest reasonably, taking into account the appropriate dimensions of the seat in both sitting and reclining states. On the other hand, the appropriate movement distance of the seat cushion facilitates the simplification of the sliding and rotating connection structures between the seat cushion and the base, and ensures sufficient support for the seat cushion, making the manufacture of the seat easier.

[0053] When the seat switches from a sitting position to a reclining position, the seat cushion flips forward to utilize the space in front of the seat, and the second backrest flips backward to utilize the space behind the seat. This allows the seat to achieve its maximum length in the reclining position through structural deformation alone, without the need for external structures, to accommodate users of different heights. Furthermore, the forward-flipping movement of the first backrest keeps the seat's center position essentially unchanged, ensuring a suitable seating position in both sitting and reclining positions. This eliminates the need for excessive additional space in the reclining position, thereby improving the seat's adaptability to vehicles of different sizes.

[0054] Thirdly, embodiments of this application provide a control module, including: at least one processor, the at least one processor being coupled to at least one memory, for executing computer instructions stored in the memory to cause the control module to perform the method provided in the second aspect.

[0055] Fourthly, embodiments of this application provide a cockpit, including a control module as provided in the third aspect and at least one seat as provided in the first aspect.

[0056] Fifthly, embodiments of this application provide a means of transportation, including a cabin as provided in the fourth aspect.

[0057] In this embodiment, in vehicles such as automobiles, the seats generally have space on both the front and rear sides when in a seated position. The seats in this embodiment can make full use of the space on both the front and rear sides of the seats to meet the large length requirements when the seats are lying flat, and are well adapted to vehicles such as automobiles.

[0058] In some implementations, the means of transportation is a car.

[0059] In some embodiments, the vehicle also includes front seats, which are spaced apart from each other and are located on the side of the first backrest away from the second backrest; the front seats are movable in a direction away from the seats and the space between the front seats is increased so that the seat cushion has room to move.

[0060] In some implementations, the vehicle has a rear sill, and when the seat is in a reclined position, the second end of the second backrest rests on the rear sill.

[0061] In this embodiment, the storage space formed between the second backrest and the bottom plate of the rear trunk can constitute a closed space, providing good privacy when storing items.

[0066] The embodiments of this application are described below with reference to the accompanying drawings.

[0067] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," "joining," and "joining" should be interpreted broadly. For example, "joining" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Movable connection" refers to a connection where the relative positional relationship can change after connection. "Rotary connection" refers to a connection where the relative positional relationship can change. "Sliding connection" refers to a connection where the relative positional relationship can change. Furthermore, the integrated structure obtained by a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components. Components A and B can be arranged relative to each other such that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, with projection C and projection D at least largely overlapping. In some embodiments, the majority overlap can be any of the following: projection C is entirely within projection D; or projection D is entirely within projection C; or projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for more than 50% of projection C or projection D.

[0068] The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," "outer," "upper," and "lower," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0069] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. "Multiple" means at least two.

[0070] Furthermore, the limitations on relative positional relationships mentioned in the embodiments of this application, such as parallelism and perpendicularity, are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0071] Please combine participation Figure 1 and Figure 2 , Figure 1 This is a simplified structural diagram of a vehicle 1000 provided in an embodiment of this application. Figure 2 yes Figure 1 A simplified schematic diagram of the internal structure of the vehicle 1000 shown.

[0072] In some embodiments, the vehicle 1000 may be a car, a ship, an aircraft, or other equipment. This embodiment mainly uses a car as an example for illustrative purposes.

[0073] In some embodiments, the vehicle 1000 may include a chassis 100, a shell 200, and a cabin 300. For example, when the vehicle 1000 is a car, the car may be, but is not limited to, a sedan, a multi-purpose vehicle (MPV), a sport / suburban utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a van, a bus, a truck, etc. The car may also be an electric vehicle, a gasoline vehicle, or a hybrid vehicle, etc., and this embodiment does not impose strict limitations on these. For ease of description, in the vehicle 1000 of this application, the direction in which the driver faces the vehicle 1000 is defined as "front," and the direction in which the driver faces away from the vehicle is defined as "rear."

[0074] For example, chassis 100 may include a power unit, energy unit, control unit, and tires, etc., to enable the vehicle to operate. The power unit, energy unit, control system, etc., may be housed inside housing 200.

[0075] In this system, the power unit transmits power to the tires to control their rotation, thereby propelling the vehicle body forward or backward. For example, the power unit can be an engine, an electric motor powertrain, or similar components.

[0076] The energy device is used to supply power to the power unit. For example, the energy device can be a battery, a fuel tank, etc. This embodiment does not specifically limit the structure of the chassis 100.

[0077] For example, housing 200 may be housing 2001 of a vehicle. Housing 200 may include housing 2001 and windshield 2002.

[0078] The housing 2001 may be a metal component. The housing 2001 is used to provide housing and protection for the vehicle 1000.

[0079] The windshield 2002 can be installed on the housing 2001. For example, the windshield 2002 can be installed on the housing 200 at a position corresponding to the front of the driver's cab of the vehicle. The windshield 2002 and the housing 200 isolate the driver's cab from the outside of the vehicle, facilitating driving and protecting the driver. The windshield 2002 can be made of transparent materials such as glass or plastic, allowing environmental information from outside the vehicle to be transmitted into the driver's cab through the windshield 2002 to meet normal driving needs.

[0080] For example, the cabin 300 may be located within the interior space of the vehicle 1000. For instance, the cabin 300 may be located inside the outer shell 200. The cabin 300 is used to accommodate a driver or passengers. The cabin 300 may also provide the driver or passengers with the function of controlling the vehicle 1000. There may be multiple cabins 300. For example, one cabin 300 may include one seating seat, or one cabin 300 may include multiple seating seats; this embodiment does not strictly limit this.

[0081] It is understood that the means of transport 1000 may include more or fewer of the above-mentioned components, and the specific composition of the means of transport 1000 is not limited here.

[0082] In some embodiments, the outer casing 200 may enclose a front engine compartment 2003, a passenger compartment 2004, and a rear cargo box 2005. The passenger compartment 2004 may be located between the front engine compartment 2003 and the rear cargo box 2005.

[0083] For example, the power unit and other components may be located in the front engine compartment 2003, in which case the vehicle is a front-wheel drive vehicle. In some other examples, the power unit may also be located in other locations, which are not specifically limited in this embodiment.

[0084] For example, the passenger cabin 2004 can form multiple rows of seating space, and each row of seating space can be equipped with a cabin 300.

[0085] For example, the number of rows of passenger space can be equal to the number of rows of cabin 300, such as passenger cabin 2004 having two rows of cabin 300, three rows of cabin 300, or more cabins 300. This example does not impose a strict limitation on the number of rows of cabin 300.

[0086] For example, the front row of seating space can be the "driver's cab," with a cabin 300 on the left for the "driver" and a cabin 300 on the right for the "co-driver." For example, the cabin 300 behind the "driver's cab" can accommodate other passengers. When there are two rows of cabins 300 behind the "driver's cab," the row closer to the driver's cab can be the middle row, and the row further away from the driver's cab can be the rear row. It is understood that the above is an exemplary description of the cabin 300 distribution in the passenger compartment 2004 and is not intended to limit the cabin 300 arrangement; the specific cabin 300 arrangement can be configured according to the specific structure of the vehicle 1000.

[0087] For example, the rear cargo box 2005 can be used to accommodate cargo. The rear cargo box 2005 may be connected to or separated from the passenger compartment 2004, without specific limitations.

[0088] Understandable, Figure 1 , Figure 2 The accompanying drawings below only schematically illustrate some of the components included in the vehicle; the actual shape, size, location, and construction of these components are not limited to these figures. Figure 1 , Figure 2 And the limitations of the figures below.

[0089] In some embodiments, the cockpit 300 may include a seat 10 and a control module (not shown). The control module is used to implement various functions to meet user needs. The control module can electrically control the seat 10 or other electronic components of the cockpit 300, or perform motion control on mechanical devices.

[0090] For example, the cockpit 300 may also include intelligent sensing devices (not shown in the figure), which may include sensors such as cameras, radar, and ultrasonic sensors to monitor the status of users and the environment inside the cockpit 300 or the vehicle 1000.

[0091] For example, the cockpit 300 may also include an intelligent control device (not shown in the figure), which can receive data from the intelligent sensing device, analyze and process the data, and issue commands to control the actuators.

[0092] For example, the cockpit 300 may also include a human-machine interface device (not shown in the figure), which may include an LCD instrument panel, a head-up display, a central control screen, voice recognition, etc., to enable information interaction between the user and the cockpit 300 or the vehicle 1000.

[0093] For example, cabin 300 may also include an air conditioning unit (not shown in the figure), which can automatically adjust the temperature and humidity inside cabin 300 or vehicle 1000 according to passenger needs.

[0094] For example, the cockpit 300 may also include an entertainment device (not shown in the figure) that can provide entertainment functions such as music and video.

[0095] For example, the cockpit 300 may also include a communication device (not shown in the figure), which can support various communication methods such as vehicle networking and the Internet to achieve information sharing and remote control.

[0096] It should be noted that the cockpit 300 provided in this application may include more or fewer of the above-mentioned components, and the specific composition of the cockpit 300 is not limited herein.

[0097] In some embodiments, the seat 10 may include a frame and a cushioning element, wherein the cushioning element is fitted over the outside of the frame.

[0098] For example, the frame serves as a supporting component of the seat 10, supporting the overall structure of the seat 10. The frame can be a frame structure to meet the requirements of structural strength and lightweighting. The frame can be made of metal materials, such as high-strength steel or aluminum alloy; this embodiment is not specifically limited to these materials.

[0099] For example, a cushioning element is used to provide appropriate support for the user and to provide a comfortable riding experience. For instance, a cushioning element may include a cushioning layer and a cover, which may be placed over the outside of the cushioning layer.

[0100] The cushioning layer provides ride comfort and shock absorption. It can be made of materials with good cushioning properties, such as sponge or memory foam.

[0101] The face mask is used to directly contact the surface of the human body, providing the user with a suitable tactile experience. The face mask can be made of genuine leather, velvet, imitation leather, fabric, etc., and this embodiment does not impose specific limitations.

[0102] The seat 10 can change its shape to switch to different usage states, allowing users to use it according to their needs and meet their usage requirements in different scenarios. For example, the seat 10 can have a sitting state (first state) for users to sit in, in which case the seat 10 can roughly take the shape of a "chair". The seat 10 can also have a reclining state (second state) for users to lie down, in which case the seat 10 can roughly take the shape of a "bed".

[0103] It is understandable that the seat 10 can automatically adjust its posture according to other systems within the cockpit 300, or the seat 10 can actively adjust its posture mechanically via its built-in adjustment buttons.

[0104] The structure and shape of seat 10 will be described in detail below.

[0105] Please see Figure 3a , Figure 3a yes Figure 1 The diagram shows the vehicle 1000 in a riding state in some embodiments.

[0106] In some embodiments, the seat 10 may include a seat cushion 1, a first backrest 2, a second backrest 3, and a base 4.

[0107] In some embodiments, the cushion 1 has a first end 11 and a second end 12 opposite to each other. Exemplarily, the first end 11 of the cushion 1 is rotatable relative to the base 4. Exemplarily, the cushion 1 is slidably connected to the base 4, that is, the cushion 1 is movable relative to the base 4.

[0108] For example, the seat cushion 1 can be roughly rectangular block structure or other irregular structure, and this embodiment does not impose specific limitations. For example, the seat cushion 1 can be used to provide sitting posture support for the user, but is not limited to this.

[0109] In some embodiments, the first backrest 2 has a first end 21 and a second end 22 opposite to each other. For example, the first end 21 of the first backrest 2 is rotatably connected to the base 4. That is, the first end 21 of the first backrest 2 can rotate relative to the base 4.

[0110] For example, the first backrest 2 can be roughly trapezoidal block structure or other irregular structure, and this embodiment does not impose specific limitations. For example, the first backrest 2 can also be used to provide back support for the user's sitting posture, but it is not limited to this.

[0111] In some embodiments, the second backrest 3 has a first end 31 and a second end 32 opposite to each other.

[0112] For example, the first end 31 of the second backrest 3 is rotatably connected to the first end 21 of the first backrest 2. That is, the first end 31 of the second backrest 3 can rotate relative to the first end 21 of the first backrest 2. However, this is not a limitation.

[0113] For example, the shape of the second backrest 3 can be approximately the same as the shape of the first backrest 2. The thickness of the second backrest 3 can be relatively thin. The second backrest 3 can be approximately trapezoidal plate structure or other irregular structure; this embodiment does not impose specific limitations.

[0114] It is understandable that the seat cushion 1, the first backrest 2, and the second backrest 3 can be directly installed on the base 4, or indirectly installed on the base 4 through other parts of the seat 10.

[0115] In some embodiments, the base 4 is used to securely connect the vehicle 1000 to the vehicle 1000 so as to fix the seat 10 in the vehicle 1000.

[0116] For example, the base 4 can be a structural component independent of the seat cushion 1, the first backrest 2, and the second backrest 3. The seat cushion 1, the first backrest 2, and the second backrest 3 can all be installed on the base 4. In this case, the seat 10 can be a one-piece structure, and the seat 10 can be installed by installing the base 4 into the vehicle 1000. For example, the base 4 can be a split structure, and the seat cushion 1, the first backrest 2, or the second backrest 3 can be installed into the vehicle 1000 through different parts of the base 4.

[0117] It is understandable that the base 4 only needs to be able to install the seat 10 in the vehicle 1000. The specific structure can be set according to actual conditions, and this embodiment does not make specific limitations.

[0118] In some embodiments, the seat 10 may further include a headrest 5. Exemplarily, the headrest 5 may be mounted on the first backrest 2 and movably mounted on the second end 22 of the first backrest 2.

[0119] For example, the headrest 5 can be slidably connected to the second end 22 of the first backrest 2. For instance, the second end 22 of the first backrest 2 can be provided with a receiving groove 221, which can be used to receive the headrest 5. The headrest 5 can be movably connected to the first backrest 2 to adjust the relative position of the headrest 5 and the first backrest 2, so that the headrest 5 can support the user's head and neck.

[0120] For example, there can be multiple headrests 5. In this case, the seat 10 can have multiple seats to accommodate multiple users simultaneously.

[0121] In some other embodiments, the seat 10 may also include armrests, seat belts, etc., which will not be listed in this embodiment.

[0122] Please refer to the following: Figure 3a and Figure 3b , Figure 3b yes Figure 1 The diagram shows the vehicle 1000 in a lying-flat state in some embodiments.

[0123] In some embodiments, the seat 10 may include a sitting state and a reclining state, and the seat 10 can switch between the sitting state and the reclining state.

[0124] like Figure 3aWhen the seat 10 is in the sitting position, the first end 11 of the seat cushion 1 is away from the first backrest 2 relative to the second end 12 of the seat cushion 1, and the second end 12 of the seat cushion 1 is against the first end 21 of the first backrest 2. The seat cushion 1 and the first backrest 2 form an angle and a sitting space. The second backrest 3 is located on the side of the first backrest 2 that faces away from the sitting space, and the second backrest 3 is against the first backrest 2. The first backrest 2 and the second backrest 3 can be in an upright position.

[0125] At this time, the seat 10 is in the shape of a "chair", and the user can sit in the seating space formed by the seat cushion 1 and the first backrest 2. The seat cushion 1 and the first backrest 2 support the user respectively. The overall posture of the seat 10 in the seating state is roughly the same as that of a normal seat 10, and the space occupied by the seat 10 in the seating state is basically the same as that occupied by the seat 10 in the prior art.

[0126] The second backrest 3 is abutted against the first backrest 2. For example, the first end 31 of the second backrest 3 abuts against the first end 21 of the first backrest 2, and the second end 32 of the second backrest 3 abuts against the second end 22 of the first backrest 2. The first backrest 2 and the second backrest 3 are relatively compact, and the second backrest 3 does not need to occupy additional space, which helps to improve space utilization.

[0127] like Figure 3b When the seat 10 is in a reclined position, the first backrest 2 is located between the seat cushion 1 and the second backrest 3. The second end 12 of the seat cushion 1, the first end 11 of the seat cushion 1, the second end 22 of the first backrest 2, the first end 21 of the first backrest 2, the first end 31 of the second backrest 3, and the second end 32 of the second backrest 3 are arranged sequentially in the direction from the seat cushion 1 to the second backrest 3. The seat cushion 1, the first backrest 2, and the second backrest 3 can all be laid flat.

[0128] At this time, the seat cushion 1, the first backrest 2, and the second backrest 3 of the seat 10 are in roughly the same position, that is, all three are laid flat. The seat cushion 1, the first backrest 2, and the second backrest 3 are arranged in sequence and can be combined to form a long support structure. Therefore, the seat 10 is in the form of a "bed". The user can lie down in the space on the top side of the seat cushion 1, the first backrest 2, and the second backrest 3. The seat cushion 1, the first backrest 2, and the second backrest 3 together provide support for the user.

[0129] See also Figure 3a and Figure 3b The seat cushion 1 moves forward and flips forward relative to the base 4, the first backrest 2 flips forward relative to the base 4 to unfold, and the second backrest 3 flips backward relative to the base 4 to unfold, so that the seat 10 switches from a sitting state to a reclining state. It is understood that there may be a sliding connection structure between the seat cushion 1 and the base 4, or there may be a rotating connection structure between the seat cushion 1 and the base 4.

[0130] In some other embodiments, the seat cushion 1 may only be slidably connected to the base 4. In this case, the seat cushion 1 moves forward only relative to the base 4 to flatten itself. However, when the seat cushion 1 needs to make more space for the first backrest 2, it must move a greater distance, requiring higher strength from the sliding connection structure between the seat cushion 1 and the first backrest 2. This necessitates a more complex structure, which is detrimental to simplifying and lightweighting the connection structure between the seat cushion 1 and the first backrest 2.

[0131] In some other embodiments, the cushion 1 may only rotate to connect to the base 4. In this case, the cushion 1 only flips forward relative to the base 4 to flatten it. The space freed up by the flipping of the cushion 1 is generally less than or equal to the width of the cushion 1 itself. In this case, it is difficult for the cushion 1 to provide enough space for the first backrest 2, and the width dimensions of the cushion 1 and the first backrest 2 are limited. Alternatively, a complex connection structure is required between the cushion 1 and the base 4 to allow the cushion 1 to free up sufficient space, and the connection strength between the cushion 1 and the base 4 is difficult to guarantee.

[0132] In this embodiment, the seat cushion 1 flattens itself out by a combination of moving forward and flipping forward, making room for the first backrest 2 to flatten out. This movement of the seat cushion 1 allows for sufficient space for the first backrest 2, which is beneficial for setting the dimensions of the seat cushion 1 and the first backrest 2 reasonably, taking into account the appropriate dimensions of the seat 10 in both sitting and reclining states. On the other hand, the appropriate movement distance of the seat cushion 1 facilitates the simplification of the sliding and rotating connection structures between the seat cushion 1 and the base 4, and ensures sufficient support for the seat cushion 1, making the manufacture of the seat 10 easier.

[0133] When the seat 10 switches from a sitting position to a reclining position, the seat cushion 1 flips forward to utilize the space in front of the seat 10, and the second backrest 3 flips backward to utilize the space behind the seat 10. This allows the seat 10 to achieve the longest possible length in the reclining position through its own structural deformation, without the need for external structures, to accommodate users of different heights. Furthermore, the forward-flipping movement of the first backrest 2 keeps the center position of the seat 10 essentially unchanged, ensuring that the seat 10 has a suitable position in both the sitting and reclining positions. This eliminates the need for excessive additional space in the reclining position, thereby improving the adaptability of the seat 10 to vehicles 1000 of different sizes.

[0134] In vehicles such as automobiles 1000, the seat 10 generally has space on the front and rear sides when in the sitting state. The seat 10 in this embodiment can make full use of the space on the front and rear sides of the seat 10, meet the large length requirement of the seat 10 when lying flat, and has good adaptability to vehicles such as automobiles 1000.

[0135] The seat cushion 1, the first backrest 2, and the second backrest 3 are all capable of rotating and can each move to a flat position. Specific details of their movement can be found later in the text. Figures 3a to 6b Description of the embodiments.

[0136] In some embodiments, when the seat 10 is in a reclining state, the first end 11 of the seat cushion 1 is spliced ​​with the second end 22 of the first backrest 2, and / or, the first end 21 of the first backrest 2 is spliced ​​with the first end 31 of the second backrest 3.

[0137] "Splicing" refers to the seamless contact or small gap between the edges of the seat cushion 1, the first backrest 2, and the second backrest 3 that are close to each other. The small gap can be an allowable error, such as a few millimeters, without affecting the use. This error may be due to factors such as the manufacturing process.

[0138] At this point, the seat cushion 1 and the first backrest 2, and the first backrest 2 and the second backrest 3 can be spliced ​​together to form a large and complete support structure. No additional support structure is needed to directly provide good support to the user, resulting in a better user experience.

[0139] In some embodiments, the seat cushion 1 has a first surface 13 and a second surface 14 facing away from each other, the first backrest 2 has a third surface 23 and a fourth surface 24 facing away from each other, and the second backrest 3 has a fifth surface 33 and a sixth surface 34 facing away from each other. The second surface 14, the fourth surface 24, and the fifth surface 33 are planar, but this is not strictly limited. The first surface 13 and the third surface 23 can be curved surfaces, but this is not strictly limited.

[0140] like Figure 3a When the seat 10 is in the sitting position, the first side 13 and the third side 23 are spliced ​​together to form a sitting space, and the fourth side 24 faces the fifth side 33.

[0141] like Figure 3b When the seat 10 is in a reclined position, the second surface 14, the fourth surface 24, and the fifth surface 33 face the same side of the seat 10, and the fourth surface 24 connects the second surface 14 and the fifth surface 33; the second surface 14, the fourth surface 24, and the fifth surface 33 are flush to form the support surface of the seat 10.

[0142] In this embodiment, when the seat 10 is in a seated position, the first surface 13 and the third surface 23 provide support for the user. The first surface 13 and the second surface 14 can be shaped appropriately to provide a more comfortable seating experience for the user. When the seat 10 is in a reclining position, the second surface 14, the fourth surface 24, and the fifth surface 33 provide support for the user. The second surface 14, the fourth surface 24, and the fifth surface 33 are flat, thus the seat 10 can provide a large and flat support surface, making it easier for the user to lie down and providing a comfortable reclining experience.

[0143] The seat 10 provides corresponding support through different surfaces in the sitting and reclining positions, which can be used to meet different usage needs by setting different surface shapes.

[0144] Here, "aligned" means that the edges of the second surface 14, the fourth surface 24, and the fifth surface 33 are aligned or approximately aligned with each other. "Approximately aligned" means that an acceptable error (such as a few millimeters, possibly due to manufacturing processes) is permissible without affecting usability. This creates a larger and more continuous support surface formed by the second surface 14, the fourth surface 24, and the fifth surface 33, providing better support and a more comfortable support experience, thus improving the user experience. For example, alignment here can also mean coplanarity; for instance, during use, the second surface 14, the fourth surface 24, and the fifth surface 33 have the same height and are located on the same horizontal plane, thus enhancing practicality.

[0145] In some embodiments, the length of the first end 11 of the seat cushion 1 is greater than the length of the second end 12 of the seat cushion 1, the length of the first end 21 of the first backrest 2 is less than the length of the second end 22 of the first backrest 2, and the length of the first end 31 of the second backrest 3 is less than the length of the second end 32 of the second backrest 3. The length directions of the seat cushion 1, the first backrest 2, and the second backrest 3 are parallel, and the length direction of the first backrest 2 is parallel to the rotation axis of the first backrest 2 and the base 4.

[0146] In this embodiment, when the seat 10 is in the sitting position, the second end 12 of the seat cushion 1, the first end 21 of the first backrest 2, and the first end 31 of the second backrest 3 are close in position and all three are relatively short. The first end 11 of the seat cushion 1 and the second end 22 of the first backrest 2 are relatively long, which helps to provide more seating space for the seat 10 in the sitting position. When the seat 10 is in the reclining position, the dimensions of the seat 10 at the joint between the first end 21 of the first backrest 2 and the first end 31 of the second backrest 3 are narrower, and the dimensions of the seat 10 at the second end 22 of the first backrest 2 and the second end 32 of the second backrest 3 are wider, which helps to maximize the load-bearing capacity of the seat 10 in the reclining position.

[0147] The vehicle 1000 has tires, and the passenger compartment 2004 needs to make way for the tires; therefore, the width of the passenger compartment 2004 at the tires is generally narrow. When the seat 10 is applied to the vehicle 1000, the seat 10 of this application can be positioned at the tire location of the passenger compartment 2004, and has a large load-bearing capacity in both sitting and reclining states. The seat 10 is highly adaptable to the vehicle 1000.

[0148] Furthermore, the length of the first end 11 of the seat cushion 1 is greater than the length of the second end 12 of the seat cushion 1. When the seat cushion 1 moves and flips, the first end 11 of the seat cushion 1 will not collide with other external components (such as the housing 2001 of the vehicle 1000). The length of the first end 21 of the first backrest 2 is less than the length of the second end 22 of the first backrest 2. The flipping motion of the first backrest 2 makes the size of the second end 22 of the first backrest 2 close to the size of the first end 11 of the seat cushion 1, thereby making the transition between the second end 22 of the first backrest 2 and the first end 11 of the seat cushion 1 smooth. The flipping motion of the second backrest 3 makes the size limitation of the second end 32 of the second backrest 3 not unrelated to the size limitation of the first end 31 of the second backrest 3 when flipping. Therefore, the motion mode and size of the seat cushion 1, the first backrest 2, and the second backrest 3 of this application are well matched.

[0149] The movement of the seat cushion 1, the first backrest 2, and the second backrest 3 will be described below.

[0150] Please combine Figures 4a to 4c , Figure 4a yes Figure 3a The diagram illustrates the usage status of the vehicle 1000 in some embodiments. Figure 1 , Figure 4b yes Figure 3a The diagram illustrates the usage status of the vehicle 1000 in some embodiments. Figure 2 , Figure 4c yes Figure 3a The diagram shows the usage status of the vehicle 1000 in some embodiments.

[0151] In some embodiments, the seat cushion 1 can move when the seat 10 switches from a sitting position to a reclining position.

[0152] like Figure 4a The seat cushion 1 can move away from the first backrest 2, that is, the seat cushion 1 can move forward.

[0153] For example, the seat cushion 1 is slidably connected to the base 4 along a first direction, which is the arrangement direction of the seat cushion 1 and the first backrest 2 when the seat 10 is in a reclined state. At this time, the moving direction of the seat cushion 1 is the same as the arrangement direction of the seat cushion 1 and the first backrest 2, which facilitates the rapid movement of the seat cushion 1 so that the seat 10 can unfold and be put into place quickly, reducing the time for the seat 10 to switch states.

[0154] The seat cushion 1 and the base 4 can be connected by a sliding connection structure. For example, the seat cushion 1 and the base 4 can be connected by a slider and a slide rail structure. The slider is slidably connected to the slide rail and can move along the set path of the slide rail, thereby allowing the seat cushion 1 to move along the corresponding path. It is understood that the seat cushion 1 and the base 4 can be connected by other existing movable connection structures, and this embodiment does not impose specific limitations on this.

[0155] For example, the rotation of the seat 1 relative to the base 4 can be driven by an independent drive structure, which may include a drive motor, etc., and this embodiment does not make specific limitations.

[0156] like Figure 4b and Figure 4c The second end 12 of the seat cushion 1 can rotate in a direction away from the first backrest 2, that is, the seat cushion 1 can be flipped forward so that the seat cushion 1 can be spread out.

[0157] For example, the seat cushion 1 is capable of rotating around a first axis. When the seat cushion 1 rotates, the first axis can be located at the first end 11 of the seat cushion 1, and the second end 12 of the seat cushion 1 rotates around the first end 11, gradually moving away from the first backrest 2. After the seat cushion 1 is flipped into position, the entire seat cushion 1 undergoes an inward and outward flip, from the first side 13 facing upward to the second side 14 facing upward.

[0158] For example, the first axis can be perpendicular to the first direction. In this case, when the seat cushion 1 is flipped, it is beneficial to allow the position of the second end 12 of the seat cushion 1 to change by a large distance, thereby changing the posture of the seat 10 to a greater extent.

[0159] The seat cushion 1 and the base 4 can be connected by a rotatable connection structure. For example, the seat cushion 1 can be rotatably connected to the base 4 via an adjuster, but this embodiment does not impose any specific limitations on this.

[0160] Since the seat cushion 1 and the base 4 can both slide and rotate, those skilled in the art will understand that the sliding connection structure and the rotating connection structure between the seat cushion 1 and the base 4 can be combined to satisfy both modes of movement. For example, the seat adjuster can be slidably connected to the base 4 so that when the seat cushion 1 moves relative to the base 4, the seat adjuster moves synchronously relative to the base 4.

[0161] For example, the rotation of the seat 1 relative to the base 4 can be driven by an independent drive structure, which may include a drive motor, etc., and this embodiment does not make specific limitations.

[0162] In some embodiments, the movement and rotation of the cushion 1 relative to the base 4 can be two independent movements; that is, the cushion 1 can move only relative to the base 4 or rotate only relative to the base 4. This can be achieved by the connection structure between the cushion 1 and the base 4. In this case, the movement of the cushion 1 relative to the base 4 and the rotation of the cushion 1 relative to the base 4 can be driven by independent power sources.

[0163] In some embodiments, the seat cushion 1 can first move forward relative to the base 4 and then flip relative to the base 4. Moving the seat cushion 1 first provides sufficient space for the flipping motion and prevents it from colliding with other components (such as the first backrest 2) during the flipping process. In other embodiments, the seat cushion 1 can first flip relative to the base 4 and then move relative to the base 4. Alternatively, the seat cushion 1 can simultaneously flip and move relative to the base 4, performing a combined motion. The specific configuration can be tailored to the needs of the seat 10; this embodiment does not impose specific limitations on this.

[0164] In this embodiment, the two motion processes of translation and flipping of the cushion 1 relative to the base 4 are performed sequentially, making the movement safer and more reliable.

[0165] In some other embodiments, the translational movement and the flipping movement of the seat cushion 1 relative to the base 4 can also be performed simultaneously. In this case, the movement process is faster, which is beneficial to make the state switching of the seat 10 faster.

[0166] like Figures 4a to 4c In this embodiment, the seat cushion 1 increases the distance between the seat cushion 1 and the first end 21 of the first backrest 2 by moving forward. The seat cushion 1 then flips over to free up the space it occupies. At this time, there is a large space between the seat cushion 1 and the first end 21 of the first backrest 2, which is beneficial for providing space for the first backrest 2 to be flipped and flattened.

[0167] Furthermore, by moving forward and flipping, the seat cushion 1 occupies the space in front of the seat 10, which helps to increase the length of the seat 10 when it is laid flat, making the seat 10 longer and more convenient for users to lie down directly.

[0168] In some embodiments, during the process of the seat 10 switching from a sitting state to a reclining state, the seat cushion 1 can move a first distance along a first direction and toward a direction away from the first backrest 2. The first distance can be greater than 20 centimeters.

[0169] For example, the first distance could be 26 centimeters.

[0170] In this embodiment, the seat cushion 1 is moved forward by a suitable distance so that both the seat cushion 1 and the first backrest 2 can be set to a suitable length, so that the seat 10 can better meet the shape of a shorter seat cushion 1 and a longer first backrest 2 when sitting, and the seat 10 has a longer length when lying flat. That is, the seat 10 can better meet the shape requirements of different states at the same time.

[0171] In some embodiments, during the process of switching the seat 10 from a sitting state to a reclining state, the seat cushion 1 rotates around its first end 11 by a first angle. The first angle can be in the range of 160° to 200°.

[0172] For example, the first angle can be 180°.

[0173] In this embodiment, the seat cushion 1 is flipped over, and the orientations of the two opposite sides of the seat cushion 1 (i.e., the first side 13 and the second side 14) are reversed, so that the seat cushion 1 can be roughly laid flat in both the sitting and lying-down states, and the seat cushion 1 can also be relatively flat in the lying-down state, making it convenient to lie down.

[0174] Please refer to the following: Figure 5a and Figure 5b , Figure 5a yes Figure 3a The diagram below shows the usage status of the vehicle 1000 in some embodiments, in Figure 4. Figure 5b yes Figure 3a The diagram shows the usage status of the vehicle 1000 in some embodiments, shown in Figure 5.

[0175] In some embodiments, when the seat 10 switches from a sitting state to a reclining state, the first backrest 2 can be flipped forward relative to the base 4, that is, the first backrest 2 can be rotated toward the direction close to the seat cushion 1 so that the first backrest 2 can be unfolded.

[0176] Among them, the first backrest 2 can move independently.

[0177] For example, the first end 21 of the first backrest 2 is rotatably connected to the base 4, and the axis of rotation of the first backrest 2 relative to the base 4 can pass through the first end 21 of the first backrest 2. During the rotation of the first backrest 2, the second end 22 of the first backrest 2 rotates forward around the first end 21 of the first backrest 2. Specifically, the second end 22 of the first backrest 2 rotates in a manner that it gets closer and closer to the first end 11 of the seat cushion 1. It can be understood that the space freed up by the seat cushion 1 after movement is occupied by the first backrest 2 after it flips forward and flattens out.

[0178] The first backrest 2 and the base 4 can be connected by a rotatable connection structure. For example, the first backrest 2 can be directly rotatably connected to the base 4 by an angle adjuster, so that the first backrest 2 is fixed to the base 4 and can rotate relative to the base 4. This embodiment does not impose specific limitations on the connection structure between the first backrest 2 and the base 4.

[0179] For example, the first backrest 2 can be driven by an independent drive structure, which may include a drive motor, etc., and this embodiment does not make specific limitations.

[0180] In some embodiments, during the process of the seat 10 switching from a sitting state to a reclining state, the first backrest 2 rotates around the first end 21 of the first backrest 2 toward the direction of the seat cushion 1 by a second angle, the second angle being in the range of 90° to 130°.

[0181] For example, the second angle could be 105°.

[0182] In this embodiment, the first backrest 2 is flipped over, changing from an upright state to a flat state. Therefore, the first backrest 2 provides good support for the user's sitting posture in the sitting state and is relatively flat in the lying state, which facilitates support for the user's lying posture.

[0183] In some implementations, when a headrest 5 is installed on the first backrest 2, the headrest 5 can be accommodated.

[0184] When seat 10 is in the seated position (see reference) Figure 3a The headrest 5 can protrude relative to the first backrest 2. For example, part of the headrest 5 is located in the receiving groove 221, and part is located outside the receiving groove 221 and protrudes relative to the first backrest 2. At this time, the headrest 5 can be in a higher position to have a suitable support position.

[0185] When the seat 10 is in a reclined position, the headrest 5 can be accommodated in the first backrest 2. For example, the headrest 5 can be located in the receiving slot 221, and when the first backrest 2 is laid flat, the headrest 5 is not exposed in the first backrest 2. At this time, the headrest 5 does not occupy the space between the seat cushion 1 and the first backrest 2, which facilitates the splicing between the seat cushion 1 and the first backrest 2.

[0186] When the seat 10 switches from a sitting position to a reclining position, the headrest 5 can move along the direction from the second end 22 of the first backrest 2 to the first end 21 of the first backrest 2 until it is retracted into the receiving groove 221.

[0187] It is understandable that during the process of the seat 10 switching from a sitting position to a reclining position, when the second backrest 3 is connected to the first backrest 2, Figure 5a and Figure 5bThe illustration shows the second backrest 3 flipping forward synchronously with the first backrest 2 (but the second backrest 3 still needs to be unfolded as follows). Figure 6a and Figure 6b (As shown, it flips backward). In some other embodiments, when the first backrest 2 flips forward relative to the base 4, the second backrest 3 may remain stationary relative to the base 4. Alternatively, when the first backrest 2 flips forward relative to the base 4, the second backrest 3 may flip backward relative to the base 4. The movement of the second backrest 3 relative to the base 4 may be independent of the movement of the first backrest 2 relative to the base 4.

[0188] Please refer to the following: Figure 6a and Figure 6b , Figure 6a yes Figure 3a The diagram shown in Figure 6 illustrates the usage status of the vehicle 1000 in some embodiments. Figure 6b yes Figure 3a The diagram illustrates the usage status of the vehicle 1000 in some embodiments. Figure 7 .

[0189] In some embodiments, when the seat 10 switches from a sitting position to a reclining position, the second backrest 3 flips backward relative to the base 4, that is, the second backrest 3 can rotate in a direction away from the seat cushion 1 so that the second backrest 3 unfolds.

[0190] The rotation of the second backrest 3 relative to the base 4 can be an independent movement.

[0191] For example, the first end 31 of the second backrest 3 is rotatably connected to the base 4, and the axis of rotation of the second backrest 3 relative to the base 4 can pass through the first end 31 of the second backrest 3. During the rotation of the second backrest 3, the second end 32 of the second backrest 3 rotates rearward around the first end 31 of the second backrest 3. Specifically, the second end 32 of the second backrest 3 rotates in a manner that the distance from the first end 11 of the seat cushion 1 increases with each rotation. It can be understood that the second backrest 3 flips backward, occupying the space behind the seat 10.

[0192] The second backrest 3 and the base 4 can be connected by a rotatable connection structure. For example, the second backrest 3 can be rotatably connected to the base 4 by an angle adjuster, so that the second backrest 3 is fixed to the base 4 and can rotate relative to the base 4. This embodiment does not impose specific limitations on the connection structure between the first backrest 2 and the base 4.

[0193] For example, the first end 31 of the second backrest 3 can be rotatably connected to the first end 21 of the first backrest 2 via an adjuster, thereby indirectly rotatably connecting to the base 4. In this case, when the seat 10 is in a seated position, the second backrest 3 easily conforms to the first backrest 2, thereby reducing the space occupied by the second backrest 3 and making the seat 10 more compact. In some other embodiments, the first end 31 of the second backrest 3 can be directly rotatably connected to the base 4.

[0194] For example, the second backrest 3 can be driven by an independent drive structure, which may include a drive motor, etc., and this embodiment does not make specific limitations.

[0195] In some embodiments, the first end 31 of the second backrest 3 is rotatably connected to the first end 21 of the first backrest 2. Since the first end 21 of the first backrest 2 is connected to the base 4, the second backrest 3 is indirectly rotatably connected to the base 4.

[0196] It is understandable that when the first backrest 2 rotates, the second backrest 3 can follow the movement of the first backrest 2, but it is not limited to this.

[0197] In this embodiment, the first end 31 of the second backrest 3 is directly connected to the first end 21 of the first backrest 2. The distance between the two is relatively close. When the seat 10 is in a sitting position, it is beneficial to make the first end 31 of the second backrest 3 and the first end 21 of the first backrest 2 close together, thereby reducing the space occupied by the second backrest 3. When the seat 10 is in a reclining position, it is beneficial to make the first end 31 of the second backrest 3 and the first end 21 of the first backrest 2 seamlessly connected, thereby improving the comfort of the seat 10.

[0198] In some embodiments, during the process of the seat 10 switching from a sitting state to a reclining state, the second backrest 3 rotates around the first end 31 of the second backrest 3 in the direction away from the first backrest 2 by a third angle; the third angle is in the range of 60° to 90°.

[0199] For example, the third angle can be 75°.

[0200] In this embodiment, the second backrest 3 is flipped over from an upright state to a flat state. This is beneficial because when the seat 10 is in a sitting position, the second backrest 3 is upright and close to the first backrest 2. The second backrest 3 occupies little space and does not waste space. Furthermore, when the seat 10 is in a reclining position, the second backrest 3 is relatively flat, which is convenient for supporting the user's reclining posture.

[0201] In some embodiments, in the vehicle 1000, when the seat 10 is in a reclined position, the second end 32 of the second backrest 3 can overlap the housing 2001. For example, the second end 32 of the second backrest 3 can overlap the tailgate sill 200a of the rear trunk 2005. In this case, the housing 2001 supports the second backrest 3, giving it stronger support capabilities and making its position more stable and reliable. Furthermore, it reduces the requirements on the connection structure between the second backrest 3 and the first backrest 2, which helps to reduce the weight of the seat 10.

[0202] Please refer to the following: Figures 3a to 6b .

[0203] In some embodiments, during the process of the seat 10 switching from a sitting state to a reclining state, the seat cushion 1, the first backrest 2, and the second backrest 3 can be driven to achieve corresponding movements.

[0204] In some implementations, the seat cushion 1 moves first, while the first backrest 2 and the second backrest 3 remain stationary. After the seat cushion 1 reaches its final position, the first backrest 2 moves, while the seat cushion 1 and the second backrest 3 remain stationary. After the first backrest 2 reaches its final position, the second backrest 3 begins to move until it reaches its final position. At this point, the seat cushion 1, the first backrest 2, and the second backrest 3 move sequentially to flatten the surface. The movement method is simple, easy to control, and relatively safe.

[0205] In some embodiments, the seat cushion 1, the first backrest 2, and the second backrest 3 can move in tandem. For example, all three move synchronously until they reach their positions and flatten out. In this case, the seat 10 switches states quickly and efficiently, resulting in a better user experience. Since the first backrest 2 occupies the position of the seat cushion 1 in the reclining state, its movement must avoid colliding with the seat cushion 1. For example, the movement of the first backrest 2 can be delayed relative to the movement of the seat cushion 1; or the movement speed of the first backrest 2 can be slower than that of the seat cushion 1, maintaining a safe distance between them, as long as no collision occurs.

[0206] It is understandable that during the process of switching the seat 10 from a reclining state to a sitting state, the movement of the seat cushion 1, the first backrest 2, and the second backrest 3 is similar to that described above. Figures 3a to 6b In this embodiment, the movement of the seat cushion 1, the first backrest 2, and the second backrest 3 are opposite, and this will not be described again in this embodiment.

[0207] Understandably, the motion control of seat 10 can be controlled by the control module of cockpit 300.

[0208] Please refer to the following: Figure 6b and Figure 7 , Figure 7 yes Figure 3aTop view of the middle seat 10 in some embodiments.

[0209] In some embodiments, when the seat 10 is in a reclined position, there is a first length between the second end 12 of the seat cushion 1 and the second end 32 of the second backrest 3; wherein the first length may be greater than or equal to 1.8 meters. In some embodiments, the first length is greater than or equal to 1.9 meters.

[0210] At this point, that is, the overall length of seat 10 is greater than or equal to 1.8 meters or 1.9 meters. Seat 10 has a relatively long length and can achieve a "bed" shape to meet the lying needs of most users.

[0211] In some embodiments, the length of the seat cushion 1 is in the range of 45 cm to 55 cm, the length of the first backrest 2 is in the range of 73 cm to 79 cm, and the length of the second backrest 3 is in the range of 63 cm to 69 cm.

[0212] For example, the length of the seat cushion 1 is 50 cm, the length of the first backrest 2 is 75 cm, and the length of the second backrest 3 is 65 cm.

[0213] In this embodiment, by reasonably setting the lengths of the seat cushion 1 and the first backrest 2, the seat 10 is positioned in a way that is convenient for the user to sit in. By reasonably setting the lengths of the first backrest 2 and the second backrest 3, the second backrest 3 can better fit against the first backrest 2 when the seat 10 is in a sitting position, reducing the space occupied. Finally, the seat 10 has a longer length when lying flat, so that the user can lie down comfortably.

[0214] Please see Figure 8 , Figure 8 yes Figure 3a The internal structure diagram of seat 10 in some embodiments.

[0215] In some embodiments, the seat cushion 1 includes a first frame 15 and a first cushioning member (not shown), the first cushioning member being disposed on the outside of the first frame 15; the first backrest 2 includes a second frame 25 and a second cushioning member (not shown), the second cushioning member being disposed on the outside of the second frame 25; and the second backrest 3 includes a third frame 35 and a third cushioning member (not shown), the third cushioning member being disposed on the outside of the third frame 35.

[0216] The two opposite sides of the seat cushion 1 and the two opposite sides of the first backrest 2 can each have a cushioning structure to provide support in different states.

[0217] The first frame 15, the second frame 25 and the third frame 35 can constitute the frame described above, and the first buffer, the second buffer and the third buffer can constitute the buffer described above.

[0218] In this embodiment, the seat cushion 1, the first backrest 2, and the second backrest 3 all have buffer structures and support structures to meet the support requirements of the seat 10 in the sitting and reclining states.

[0219] Please refer to the following: Figure 8 and Figure 9 , Figure 9 yes Figure 8 A schematic diagram of the structure of the first connecting component 6.

[0220] In some embodiments, the seat 10 further includes a first connecting component 6.

[0221] The first connecting component 6 is used to movably connect the seat cushion 1 and the base 4, so that the seat cushion 1 can move relative to the base 4. For example, the first connecting component 6 is used to enable the seat cushion 1 to rotate or slide relative to the base 4 as described above.

[0222] In some embodiments, the first connecting assembly 6 includes a slide rail 61 and a bracket 62. The slide rail 61 is slidably connected to the bracket 62. One of the slide rail 61 and the bracket 62 is fixedly connected to the base 4, and the other is rotatably connected to the cushion 1. In this embodiment, the cushion 1 is slidably connected to the base 4 by the slide rail 61 and the bracket 62, which facilitates the linear movement of the cushion 1 relative to the base 4. Furthermore, the slide rail 61 and the bracket 62 have a simple and reliable structure, strong load-bearing capacity, and are easy to manufacture.

[0223] For example, the slide rail 61 and the bracket 62 can move relative to each other. For instance, a power component such as a motor can be provided, and the power component can be fixed to one of the slide rail 61 and the bracket 62, and then the other of the slide rail 61 and the bracket 62 can be connected by a transmission connection (such as a threaded screw, gear meshing, worm gear, etc.) so that the slide rail 61 and the bracket 62 can be driven to move relative to each other by the power component.

[0224] For example, the slide rail 61 can be fixedly connected to the base 4, and the bracket 62 is connected to the first frame 15 of the cushion 1. The bracket 62 can move on the slide rail 61. For example, if the slide rail 61 extends in a first direction, the cushion 1 can move along the first direction with the bracket 62.

[0225] For example, the bracket 62 may include a sliding part 621, a support rod 622, and a connecting part 623. The support rod 622 and the connecting part 623 are both fixed to the sliding part 621. The sliding part 621 is slidably connected to the slide rail 61, and the connecting part 623 is rotatably connected to the seat cushion 1. When the seat 10 is in the sitting state, the support rod 622 is closer to the second end 12 of the seat cushion 1 than the first end 11 of the seat cushion 1, so that the support rod 622 supports the seat cushion 1.

[0226] The connecting part 623 can rotatably connect to the first frame 15 of the seat cushion 1. There can be two connecting parts 623, with the two connecting parts 623 located on both sides of the first frame 15.

[0227] When the seat 10 is in the seated position, the support rod 622 can be located between the first frame 15 and the slide rail 61.

[0228] At this time, the support rod 622 can provide good support for the seat cushion 1, so that the seat 10 has good load-bearing capacity when seated.

[0229] In some embodiments, the first connecting component 6 may further include a first power member 63 and a first angle adjuster 64. The first power member 63 is connected to the first angle adjuster 64. The first power member 63 is fixedly installed on the seat cushion 1. The angle adjuster is rotatably connected to the seat cushion 1 and the bracket 62. The seat cushion 1 is driven to rotate by the first power member 63.

[0230] For example, the first power member 63 may be located at the first seat cushion 1. The first power member 63 drives the seat cushion 1 to rotate relative to the base 4 by outputting torque.

[0231] For example, the first adjuster 64 has a limiting portion at the extreme position of movement to limit the rotation of the seat cushion 1. For example, when the seat 10 is in a sitting state and a reclining state, the first adjuster 64 is at two extreme positions of rotation in these two states, respectively, to limit and support the seat cushion 1.

[0232] In this embodiment, by setting the first power component 63 and the first angle adjuster 64, the connection structure between the seat cushion 1 and the bracket 62 is simple, reliable, easy to manufacture, and has good load-bearing capacity.

[0233] In some embodiments, the seat 10 further includes a second connecting assembly 7, which includes a second adjuster 71 and a second power member 72. The second adjuster 71 is rotatably connected to the first backrest 2 and the base 4, and the second power member 72 is drively connected to the second adjuster 71 and is used to drive the first backrest 2 to rotate.

[0234] For example, the second power component 72 may be installed on the first backrest 2, but is not limited thereto.

[0235] For example, the second adjuster 71 has a limiting portion at its extreme position to restrict the position of the first backrest 2. For instance, when the seat 10 is in a sitting position and a reclining position, the second adjuster 71 is at two extreme rotational positions in these two states, respectively, to limit and support the seat cushion 1. It is understood that the second adjuster 71 can have more limiting angles so that the first backrest 2 can have strong support and impact resistance in multiple positions.

[0236] In this embodiment, by setting the second angle adjuster 71 and the second power component 72, the connection structure between the first backrest 2 and the base 4 is simple, reliable, easy to manufacture, and has good load-bearing capacity.

[0237] Please refer to the following: Figure 8 and Figure 10 , Figure 10 yes Figure 8 A partial structural schematic diagram of seat 10 is shown.

[0238] In some embodiments, the seat may also include a third connection assembly 8, which includes a third power component 81 and a transmission assembly 82.

[0239] The third power component 81 is fixed to the first backrest 2, and the transmission component 82 is connected to the second backrest 3. The third power component 81 drives the second backrest 3 to rotate through the transmission component 82.

[0240] For example, the third power component 81 and the second power component 72 can both be fixed to the first backrest 2, and the third power component 81 and the second power component 72 can be arranged side by side. The third power component 81 and the second power component 72 can be enclosed within the first backrest 2.

[0241] For example, the transmission assembly 82 is used to transmit the power (such as torque) of the third power member 81 to the second backrest 3, and to cause the second backrest 3 to rotate. For example, the transmission assembly 82 can be a gear and rack assembly, or a linkage assembly, etc., and this embodiment does not impose specific limitations.

[0242] In this embodiment, by setting the third connecting component 8, the second backrest 3 is driven by another transmission component 82, which makes the position setting of the third power component 81 more flexible and facilitates the hidden setting of the third connecting component 8.

[0243] Please see Figure 11 , Figure 11 yes Figure 3a The diagram shows the vehicle 1000 in a third state in some embodiments.

[0244] In some embodiments, the seat may also include a third state. In this state, both the seat cushion 1 and the first backrest 2 are laid flat, the first end 11 of the seat cushion 1 is opposite to the second end 22 of the first backrest 2, and the first backrest 2 and the second backrest 3 have a second included angle.

[0245] For example, the direction in which the second end 12 of the seat cushion 1 points to the first end 11 of the seat cushion 1 is approximately parallel to the direction in which the second end 22 of the first backrest 2 points to the first end 21. However, this is not a limitation.

[0246] For example, the second surface 14 and the fourth surface 24 can be parallel. The second surface 14 and the fourth surface 24 can be joined together to form a larger load-bearing surface. For example, the second surface 14 and the fourth surface 24 can be coplanar.

[0247] For example, the included angle between the fourth face 24 and the fifth face 33 is the second included angle. For example, the second included angle can be greater than 45°, or the second included angle can be greater than 90°.

[0248] See also Figure 3a and Figure 11 When the seat 10 switches from the sitting state to the third state, the seat cushion 1 flips forward and flattens, the first backrest 2 flips forward and flattens, and the third backrest rotates to form a second angle with the first backrest 2.

[0249] In this embodiment, the seat cushion 1 and the first backrest 2 can be laid flat to have a long bearing size and a large bearing area, and the second backrest 3 can be erected to provide back support for the user. The seat 10 can meet the user's needs for semi-reclining or other postures, thereby meeting the user's needs for movie watching, office work and other usage scenarios.

[0250] Furthermore, the second backrest 3 can isolate the space in front of it from the space behind it, and the seat 10 has good privacy.

[0251] Please see Figure 12 , Figure 12 yes Figure 3a The diagram shows the vehicle 1000 in a fourth state in some embodiments.

[0252] In some embodiments, the seat 10 may also include a fourth state. In this state, the first backrest 2 is upright, the seat cushion 1 is joined to the first backrest 2, the seat cushion 1 and the first backrest 2 form a first angle and enclose a seating space, the second backrest 3 is laid flat, and the second backrest 3 and the first backrest 2 form a third angle.

[0253] For example, the direction in which the first end 11 of the seat cushion 1 points to the second end 12 of the seat cushion 1 can be approximately parallel to the direction in which the first end 31 of the second backrest 3 points to the second end 32. However, this is not a limitation.

[0254] For example, the included angle between the fourth face 24 and the fifth face 33 is the second included angle. For instance, the second included angle can be greater than 30°, or it can be less than 90°.

[0255] For example, a storage space is formed between the second backrest 3 and the bottom plate of the trunk. For instance, the second end 32 of the second backrest 3 can overlap the rear sill 200a of the trunk. In this case, the storage space can form a closed space, providing good privacy when storing items.

[0256] See also Figure 3a and Figure 12 When the seat 10 switches from the sitting state to the fourth state, the third backrest flips backward and forms a third angle with the first backrest 2.

[0257] In this embodiment, in addition to meeting the user's seating needs, the seat 10 also allows the second backrest 3 to divide the space behind the first backrest 2 by setting the position of the second backrest 3, which is conducive to the diversified use of the space behind the seat 10 and improves the user experience.

[0258] Please refer to the following: Figure 13 and Figure 14 , Figure 13 yes Figure 2 The vehicle 1000 shown is in use in some embodiments. Figure 1 , Figure 14 yes Figure 2 The vehicle 1000 shown is in use in some embodiments. Figure 2 .

[0259] In some embodiments, the vehicle 1000 also includes a front seat 400, which is spaced apart from the seat 10 and is located on the side of the first backrest 2 away from the second backrest 3.

[0260] When there is a front seat 400 in front of the seat 10 of this application, if the distance between the two is close, the front seat 400 can be moved forward to leave enough space between them, which facilitates the forward movement and flipping of the seat cushion 1 of the seat 10 of this application, thereby enabling the seat 10 to achieve a longer length when lying flat.

[0261] For example, the front seat 400 can be connected to the floor of the housing 200 of the vehicle 1000 via a sliding structure. For instance, the front seat 400 is capable of moving in a first direction.

[0262] For example, the movement of the front seat 400 can be associated with the state switching of the seat 10 of this application, controlling the movement of the front seat 400 before or during the movement of the seat cushion 1. In this case, the front seat 400 can be moved electrically. In some other embodiments, the front seat 400 can be moved manually.

[0263] In some embodiments, this application provides a control method for controlling a seat. The control method may include steps S102 to S108. Steps S102 to S108 enable the seat to switch from a sitting state to a reclining state.

[0264] In step S102, the seat is moved forward relative to the base. That is, the seat cushion can move away from the first backrest.

[0265] For example, the seat cushion is slidably connected to the base along a first direction, which is the arrangement direction of the seat cushion and the first backrest when the seat is in a reclined state. At this time, the movement direction of the seat cushion is the same as the arrangement direction of the seat cushion and the first backrest, which facilitates the rapid movement of the seat cushion so that the seat can unfold into place quickly, reducing the time for the seat to switch states.

[0266] Step S104: Control the seat cushion to flip forward relative to the base. That is, the seat cushion can rotate in a direction away from the first backrest so that the seat cushion can be spread out.

[0267] For example, when the cushion rotates, the axis of rotation of the cushion relative to the base can be located at the first end of the cushion, and the second end of the cushion rotates around the first end of the cushion, gradually moving away from the first backrest. After the cushion is flipped into place, the entire cushion is flipped inside out, from the first side facing up to the second side facing up.

[0268] Step S106: Control the first backrest to flip forward relative to the base. That is, the first backrest can rotate towards the direction close to the seat cushion so that the first backrest can unfold.

[0269] For example, a first end of the first backrest is rotatably connected to a base, and the axis of rotation of the first backrest relative to the base can pass through the first end of the first backrest. During the rotation of the first backrest, a second end of the first backrest rotates forward around the first end of the first backrest. Specifically, the second end of the first backrest rotates in a manner that it gets closer and closer to the first end of the seat cushion. It can be understood that the space freed up by the seat cushion after movement is occupied by the first backrest flipping forward and flattening itself.

[0270] In step S108, the second backrest is controlled to flip backward relative to the base. That is, the second backrest can rotate in a direction away from the seat cushion so that the second backrest can unfold.

[0271] For example, the first end of the second backrest is rotatably connected to the base, and the axis of rotation of the second backrest relative to the base can pass through the first end of the second backrest. During the rotation of the second backrest, the second end of the second backrest rotates rearward around the first end of the second backrest. Specifically, the second end of the second backrest rotates in a manner that the distance from the first end of the seat cushion increases with each rotation. It can be understood that the second backrest flips backward, occupying space behind the seat.

[0272] It is understandable that each step from S102 to S108 can be executed independently, and each step can be executed before, during, or after other steps, as long as the seat cushion and the first backrest are avoided from colliding during execution.

[0273] For example, steps S102 to S108 can be executed sequentially, or steps S102 to S108 can be executed synchronously.

[0274] In some embodiments, the seat can switch from a reclining state to a sitting state, and the seat control method may further include: Step S202: Control the seat to move backward relative to the base.

[0275] Step S204: Control the seat cushion to flip backward relative to the base.

[0276] Step S206: Control the first backrest to flip backward relative to the base.

[0277] Step S208: Control the second backrest to flip forward relative to the base.

[0278] It is understandable that the process of controlling the seat to switch from a reclining state to a sitting state is roughly the opposite of the process of controlling the seat to switch from a sitting state to a reclining state, and will not be described in detail in this embodiment.

[0279] The execution and storage entities of the above control methods will be introduced next.

[0280] In some embodiments, the control module may include a control unit that performs the control method described above, and the control unit in the control device may be used to perform the corresponding process of the control method described above.

[0281] It should be understood that the division of units in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. All units of the above device can be implemented entirely through processor-invoked software, entirely through hardware circuits, or partially through processor-invoked software with the remaining parts implemented through hardware circuits.
