Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a vehicle and its control method. Background Technology

[0002] With the rapid development of vehicles, people's needs for vehicles have increased beyond just transportation, such as requiring office or leisure space inside the car. Within the limited space of a vehicle's interior, seats occupy a significant portion of the space, making it difficult to meet these needs. The solution is for at least one seat to be foldable and stowed away, changing the interior space layout to better suit user requirements.

[0003] In related technologies, vehicles are inconvenient to use. Summary of the Invention

[0004] This application provides a vehicle and its control method to make the vehicle easy to use.

[0005] The technical solution of this application embodiment is implemented as follows: The first aspect of this application provides a vehicle, including... The vehicle body includes a chassis, the chassis having a downwardly recessed storage cavity; A connecting structure is rotatably connected to the chassis. The rotation center line of the connecting structure relative to the chassis is a first rotation axis. The first rotation axis is arranged to intersect with the vertical direction. The connecting structure can rotate around the first rotation axis so that the connecting structure can be housed in the storage cavity. At least one seat, including a seat cushion and a backrest rotatably connected to each other, wherein the seat cushion of at least one of the seats is rotatably connected to the connecting structure, the rotation center line of the seat cushion relative to the connecting structure is a second rotation axis, the second rotation axis is arranged intersecting the vertical direction, the seat has a use state and a storage state located in the storage cavity, and the seat cushion is capable of rotating about the second rotation axis to allow the seat to be stored in the storage cavity; When the seat is in use, the first rotation axis and the second rotation axis are located on opposite sides of the connecting structure along the vertical direction. When the seat is in the storage state, the connecting structure is located below the seat cushion.

[0006] In this embodiment, the vertical protrusion of the seat cushion and backrest outside the storage cavity is reduced, and the vertical space occupied by the seat cushion and backrest in the storage cavity is reduced, thereby reducing the space occupied by the seat and connecting structure after storage, making the vehicle more convenient to use.

[0007] In some embodiments, the connecting structure is rotatable about the first rotation axis in a first rotation direction to house the connecting structure into the storage cavity, the seat cushion is rotatable about the second rotation axis in a second rotation direction to house the seat into the storage cavity, and the backrest is rotatable relative to the seat cushion in a third rotation direction to fold the backrest and the seat cushion together. The first and second rotation directions are opposite in orientation, and the second and third rotation directions are the same in orientation.

[0008] In this embodiment, the rotation direction of the connecting structure is opposite to the rotation direction of the backrest, so that the storage cavity is located as far away from the seat cushion as possible. When the seat is in use, the storage cavity occupies less space in front of the seat and reduces the impact of the storage cavity on the use of the seat.

[0009] In some embodiments, the first rotation axis is located on the lower side of the storage cavity.

[0010] In this embodiment, the end of the connecting structure facing the first rotation axis is placed close to the cavity wall on the lower side of the storage cavity to improve the space utilization rate inside the storage cavity.

[0011] In some embodiments, the first rotation axis is parallel to the second rotation axis.

[0012] In this embodiment, the seat cushion can fit as closely as possible to the connecting structure after the seat is folded up, thereby reducing the space occupied by the folded seat and the connecting structure.

[0013] In some embodiments, the connecting structures are respectively provided on opposite sides of the seat along the lateral direction, and the lateral direction is arranged to intersect the vertical direction and the front-back direction.

[0014] In this embodiment, the connecting structure supports the seat on both sides in the lateral direction, thereby improving the stability of the seat.

[0015] In some embodiments, the connecting structure includes a first segment, a second segment, and a third segment connected in sequence. The first segment is rotatably connected to the seat cushion and rotates about a second rotation axis. The third segment is rotatably connected to the chassis and rotates about the first rotation axis. In the two connecting structures located at both ends of the seat cushion along the lateral direction, the second segment at both ends and the third segment at both ends are located between the first segments at both ends along the lateral direction, and the third segment at both ends is located between the second segments at both ends along the lateral direction.

[0016] In this embodiment, the end of the connecting structure away from the first section bends laterally toward the center of the seat cushion. The storage cavity does not need to reserve extra space on the opposite sides laterally to accommodate and avoid the rotating connection part between the third section and the chassis, thereby improving the space utilization of the storage cavity and enhancing the rigidity and strength of the connecting structure.

[0017] In some embodiments, when the seat is in use, the thickness of the front side of the seat cushion is greater than the thickness of the rear side of the seat cushion, the storage cavity is formed in the trunk of the vehicle, the lower wall of the storage cavity is a first wall, the first wall is inclined, and the rear end of the first wall is higher than the front end of the first wall.

[0018] In this embodiment, based on the fact that the dimensions of the front and rear ends of the storage cavity in the vertical direction meet the requirements for storing the seat, the rear end of the first wall is made farther from the ground in the vertical direction to increase the departure angle of the vehicle.

[0019] In some embodiments, the connecting structure has a protrusion, and the seat cushion is rotatably connected to the protrusion. When the seat is in the use state, the protrusion protrudes toward the front end of the seat cushion in the front-back direction, and the second rotation axis is located on the side of the protrusion toward the front end of the seat cushion in the front-back direction. The front-back direction is arranged intersecting the vertical direction.

[0020] In this embodiment, the second rotation axis is positioned close to the front side of the seat cushion, so that there is sufficient space in the upper and lower directions of the seat cushion to accommodate the part that is rotatably connected to the connecting structure.

[0021] In some embodiments, the vehicle body further includes a first locking part connected to the chassis, and the seat includes a second locking part disposed on the seat cushion. When the seat is in the use state, the first locking part can lock with the second locking part to restrict the seat cushion from rotating about the second rotation axis and the connecting structure from rotating about the first rotation axis.

[0022] In this embodiment, the seat cushion and connecting structure do not rotate when the seat is in use, thereby improving the safety of the seat.

[0023] In some embodiments, the vehicle further includes a drive device disposed on the vehicle body. The drive device includes a first drive device and a second drive device. The first drive device is driven to the connecting structure to drive the connecting structure to rotate about the first rotation axis and / or drive the seat cushion to rotate about the second rotation axis. The vehicle includes a rotating structure. The backrest and the seat cushion are respectively connected to the rotating structure. The second drive device is driven to the rotating structure to drive the rotating structure to rotate the backrest relative to the seat cushion.

[0024] In this embodiment of the application, by setting a first driving device and a second driving device, the manual operation of the user is reduced and the degree of vehicle automation is improved.

[0025] In some embodiments, the number of seats is at least two, and the at least two seats are arranged laterally. The vehicle body also includes at least one slide rail connected to the chassis, the slide rail extending in the front-rear direction, one of the slide rails being a first slide rail, the first slide rail being arranged laterally spaced from the storage cavity, one of the seats being slidably disposed on the first slide rail, the front-rear direction being intersected with the vertical direction, and the lateral direction being intersected with both the front-rear direction and the vertical direction.

[0026] In this embodiment, the position of one of the seats in the vehicle along the front-to-back direction is changed to improve the versatility of the vehicle's interior space.

[0027] In some embodiments, the vehicle further includes at least one armrest box, and the number of slide rails is at least two, wherein the other slide rail is a second slide rail located along the lateral direction between two adjacent seats along the lateral direction, and at least one armrest box is slidably disposed on the second slide rail.

[0028] In this embodiment, the movable armrest box provides a space for movement between two adjacent seats in the lateral direction, making it convenient for the user to move back and forth in the vehicle from the space between the two adjacent seats in the lateral direction.

[0029] In some embodiments, the number of armrest boxes is at least two, and the at least two armrest boxes are slidably disposed on the second slide rail along the front-back direction.

[0030] In this embodiment, the armrest box can adapt to the position of the moved seat, and at least two armrest boxes can simultaneously meet the usage needs of users in the front and rear seats.

[0031] In some embodiments, the vehicle further includes a folding table, a slider, and a slide rail. The slide rail is mounted on the chassis and extends along the front-rear direction. The seat disposed on the first slide rail is arranged along the slide rail in the front-rear direction. The slider is slidably disposed on the slide rail. The folding table is detachably connected to the slider. When the folding table is in an unfolded state, it is mounted on the slider. When the folding table is in a stowed state, it is separated from the slider.

[0032] In this embodiment, the slider can move the folding table along the front and back direction, so that the folding table adapts to the position of the seat after sliding, increasing the diversity of the interior space layout of the vehicle.

[0033] In some embodiments, the vehicle further includes a cover plate, which covers the opening of the storage cavity when the seat is in the retracted state, with the seat located below the cover plate.

[0034] In this embodiment, the cover plate conceals the stored seat, and the cover plate can provide a relatively flat support surface, making it convenient to use the space above the storage cavity to carry items.

[0035] In some embodiments, the chassis includes a support plate, at least three crossbeams and at least four longitudinal beams, the crossbeams and the longitudinal beams being respectively mounted on the support plate, the longitudinal beams extending in a front-rear direction, the at least four longitudinal beams being spaced apart in a transverse direction, the crossbeams extending in a transverse direction, the at least three crossbeams being spaced apart in the front-rear direction, the crossbeams being located in a transverse direction between two adjacent longitudinal beams, and the storage cavity being formed in the support plate.

[0036] In this embodiment, the crossbeam and longitudinal beam can be set at the stress position of the support plate. While meeting the chassis load requirements, the thickness of the support plate is reduced, the flatness of the support plate is improved, and there is enough space above the support plate for seat movement, which can reduce the difficulty of changing the interior space layout.

[0037] A second aspect of this application provides a vehicle control method applied to the vehicle, the control method comprising: The connecting structure is controlled to rotate relative to the chassis so that the seat is retracted into the storage cavity.

[0038] In this embodiment, the automatic control connection structure rotates relative to the chassis to retract the seat into the storage cavity, thereby improving the automation level of the vehicle.

[0039] In some embodiments, the vehicle includes at least two seats and an armrest box, wherein one of the seats is rotatably connected to a connecting structure, and at least one of the other seats is movably disposed on the chassis, and the armrest box is movably disposed on the chassis; After controlling the connecting structure to rotate relative to the chassis so that the seat is retracted into the storage cavity, the control method further includes: Control the movement of one of the seats and the armrest box.

[0040] In this embodiment, the movement of the seat and armrest box is automatically controlled, and the layout of the interior space is automatically changed, thereby improving the degree of vehicle automation.

[0041] The embodiments of this application have the following beneficial effects: The vehicle provided in this application embodiment includes at least one seat comprising a seat cushion and a backrest rotatably connected to each other. The backrest can rotate relative to the seat cushion to fold the seat. A connecting structure can rotate around a first rotation axis to be stored in a storage cavity and lie within the storage cavity. The connecting structure does not need to be vertically arranged within the storage cavity, reducing the space occupied by the connecting structure within the storage cavity. The seat cushion of at least one seat is rotatably connected to the connecting structure. The rotation center line of the seat cushion relative to the connecting structure is a second rotation axis. When the seat is in use, the first rotation axis and the second rotation axis are located on opposite sides of the connecting structure in the vertical direction. After the seat is folded, the connecting structure rotates around the first rotation axis, causing the seat cushion to move into the storage cavity. Then, the seat cushion rotates around the second rotation axis relative to the connecting structure, so that the seat cushion and backrest are completely stored within the storage cavity, reducing the vertical protrusion of the seat cushion and backrest outside the storage cavity and reducing the vertical space occupied by the seat cushion and backrest within the storage cavity. By using the first and second rotation axes to adjust the relative positions of the seat and the connecting structure, the connecting structure is located under the seat cushion and the seat cushion is located under the backrest when the seat is folded into the storage cavity. The connecting structure does not protrude above the seat cushion, reducing the space occupied by the connecting structure outside the storage cavity and reducing the space occupied by the folded seat and connecting structure, making the vehicle more convenient to use.

[0044] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0045] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0046] In related technologies, a vehicle includes a body, a connecting structure, and at least one seat. The body includes a chassis with a storage cavity. The seat cushion is fixedly connected to the connecting structure, which is rotatably connected to the chassis. The connecting structure can rotate the seat to allow it to be stored in the storage cavity. Because the seat cushion is fixedly connected to the connecting structure, it cannot rotate relative to the connecting structure, and the positions of the seat cushion and the connecting structure cannot be adjusted relative to each other. After the seat is stored in the storage cavity, the connecting structure protrudes above the seat cushion, occupying space in the passenger compartment outside the storage cavity. Alternatively, the connecting structure can be recessed into the storage cavity. The stored seat and the vertical connecting structure occupy a significant amount of space within the storage cavity, making the vehicle inconvenient to use.

[0047] This application provides a vehicle; please refer to the embodiments described herein. Figures 1-8 The vehicle includes a body 1, a connecting structure 3, and at least one seat 2. The body 1 includes a chassis 11 with a recessed storage cavity 111. The connecting structure 3 is rotatably connected to the chassis 11, and the rotation center line of the connecting structure 3 relative to the chassis 11 is a first rotation axis 31. The first rotation axis 31 is arranged intersecting the vertical direction, and the connecting structure 3 can rotate around the first rotation axis 31 to be stored in the storage cavity 111. At least one seat 2 includes a seat cushion 21 and a backrest 22 rotatably connected to each other. The seat cushion 21 of at least one seat 2 is rotatably connected to the backrest 22. The connecting structure 3 is rotatably connected, and the rotation center line of the seat cushion 21 relative to the connecting structure 3 is the second rotation axis 32. The second rotation axis 32 is arranged intersecting the vertical direction. The seat 2 has a use state and a storage state located in the storage cavity 111. The seat cushion 21 can rotate around the second rotation axis 32 to store the seat 2 in the storage cavity 111. When the seat 2 is in the use state, the first rotation axis 31 and the second rotation axis 32 are located on opposite sides of the connecting structure 3 in the vertical direction. When the seat 2 is in the storage state, the connecting structure 3 is located below the seat cushion 21.

[0048] It should be noted that the forward and backward directions are the directions in which the vehicle travels straight.

[0049] It should be noted that the first rotation axis 31 being arranged intersecting with the vertical direction means that the first rotation axis 31 is not parallel to the vertical direction.

[0050] It should be noted that the second rotation axis 32 being arranged intersecting the vertical direction means that the second rotation axis 32 is not parallel to the vertical direction.

[0051] It should be noted that at least one seat 2 includes a seat cushion 21 and a backrest 22 that are rotatably connected to each other, with their rotation center lines intersecting the vertical direction. The backrest 22 rotates relative to the seat cushion 21, causing one end of the backrest 22 to move closer to or further away from the seat cushion 21.

[0052] The up and down direction is as shown by arrow R1 in the figure.

[0053] The forward and backward direction is as shown by arrow R2 in the figure.

[0054] The horizontal direction is as shown by arrow R3 in the figure.

[0055] In this embodiment, at least one seat 2 includes a seat cushion 21 and a backrest 22 rotatably connected to each other. The backrest 22 can rotate relative to the seat cushion 21 to fold the seat 2. The connecting structure 3 can rotate about a first rotation axis 31 to be stored in and lie in the storage cavity 111. The connecting structure 3 does not need to be vertically arranged in the storage cavity 111, reducing the space occupied by the connecting structure 3 in the storage cavity 111. The seat cushion 21 of at least one seat 2 is rotatably connected to the connecting structure 3, and the rotation center line of the seat cushion 21 relative to the connecting structure 3 is the second rotation axis. Line 32: When the seat 2 is in use, the first rotation axis 31 and the second rotation axis 32 are located on opposite sides of the connecting structure 3 in the vertical direction. After the seat 2 is folded, the connecting structure 3 rotates around the first rotation axis 31, causing the seat cushion 21 to move into the storage cavity 111. Then, the seat cushion 21 rotates around the second rotation axis 32 relative to the connecting structure 3, so that the seat cushion 21 and the backrest 22 are completely stored in the storage cavity 111, reducing the vertical protrusion of the seat cushion 21 and the backrest 22 outside the storage cavity 111 and reducing the vertical space occupied by the seat cushion 21 and the backrest 22 in the storage cavity 111. By using the first rotation axis 31 and the second rotation axis 32 to rotate at two positions, the relative positions of the seat 2 and the connecting structure 3 can be adjusted. When the seat 2 is stored in the storage cavity 111, the connecting structure 3 is located below the seat cushion 21, and the seat cushion 21 is located below the backrest 22. The connecting structure 3 will not protrude above the seat cushion 21, reducing the space occupied by the connecting structure 3 outside the storage cavity 111 and reducing the space occupied by the stored seat 2 and the connecting structure 3, making the vehicle more convenient to use.

[0056] In some embodiments, please refer to Figures 3-5 The connecting structure 3 can rotate around the first rotation axis 31 in the first direction of rotation so that the connecting structure 3 can be stored in the storage cavity 111. The seat cushion 21 can rotate around the second rotation axis 32 in the second direction of rotation so that the seat 2 can be stored in the storage cavity 111. The backrest 22 can rotate relative to the seat cushion 21 in the third direction of rotation so that the backrest 22 and the seat cushion 21 can be folded. The first and second directions of rotation are opposite, and the second and third directions of rotation are the same.

[0057] For example, when the connecting structure 3 is housed in the receiving cavity 111, the connecting structure 3 can rotate about the first rotation axis 31 in a fourth rotation direction so that the connecting structure 3 rotates out of the receiving cavity 111. The fourth rotation direction is opposite to the first rotation direction.

[0058] For example, when the seat 2 is in the stowed state, the cushion 21 can rotate around the second rotation axis 32 in the fifth rotation direction so that the seat 2 rotates out of the stowed cavity 111, and the fifth rotation direction is opposite to the second rotation direction.

[0059] For example, the backrest 22 can rotate relative to the seat cushion 21 in a sixth rotational direction to unfold the backrest 22, the sixth rotational direction being opposite to the third rotational direction.

[0060] The first direction of rotation is shown by arrow R4 in the figure.

[0061] The second direction of rotation is shown by arrow R5 in the figure.

[0062] The third direction of rotation is shown by arrow R6 in the figure.

[0063] It should be noted that when the seat 2 is in use, the seat cushion 21 is located in front of the backrest 22.

[0064] For example, the storage cavity 111 is located on the rear side of the seat 2.

[0065] In this embodiment, the connecting structure 3 can rotate around the first rotation axis 31 in the first direction of rotation so that the connecting structure 3 can be stored in the storage cavity 111. The seat cushion 21 can rotate around the second rotation axis 32 in the second direction of rotation so that the seat 2 can be stored in the storage cavity 111. The backrest 22 can rotate relative to the seat cushion 21 in the third direction of rotation so that the backrest 22 and the seat cushion 21 can be folded. The first and second directions of rotation are opposite in orientation, and the second and third directions of rotation are the same in orientation. When the seat 2 is stored, the rotation direction of the connecting structure 3 is opposite to the rotation direction of the backrest 22, so that the storage cavity 111 is located as far away from the seat cushion 21 as possible. When the seat 2 is in use, the storage cavity 111 occupies less space in front of the seat 2 and reduces the impact of the storage cavity 111 on the use of the seat 2.

[0066] It is understood that the orientations of the first and second rotations are not necessarily opposite, and the orientations of the second and third rotations are not necessarily the same. For example, the orientations of the first and second rotations are opposite, and the orientations of the second and third rotations are opposite.

[0067] In some embodiments, please refer to Figures 3-5 The first rotation axis 31 is located on the lower side of the storage cavity 111.

[0068] It should be noted that "the first rotation axis 31 is located on the lower side of the storage cavity 111" means that the first rotation axis 31 is located on the side of the storage cavity 111 facing the lower cavity wall of the storage cavity 111 in the vertical direction. The first rotation axis 31 is located inside the storage cavity 111.

[0069] For example, the base has a first rotating seat and a first rotating shaft, the first rotating shaft passes through the connecting structure 3, the first rotating axis 31 is formed on the first rotating shaft, the connecting structure 3 rotates around the first rotating shaft, and the first rotating seat is installed on the cavity wall of the storage cavity 111 on one side in the front-back direction.

[0070] In this embodiment, when the seat 2 is in the storage state, the connecting structure 3 is located below the seat cushion 21, and the first rotation axis 31 is located on the lower side of the storage cavity 111. When the seat 2 is stored in the storage cavity 111, the end of the connecting structure 3 facing the first rotation axis 31 is close to the cavity wall on the lower side of the storage cavity 111, thereby improving the space utilization rate of the storage cavity 111.

[0071] It is understood that the first rotation axis 31 is not limited to being located on the lower side of the storage cavity 111. Exemplarily, the first rotation axis 31 is located on the upper side of the storage cavity 111.

[0072] In some embodiments, the first rotation axis 31 is parallel to the second rotation axis 32.

[0073] For example, the rotation center line of the backrest 22 relative to the seat cushion 21 is parallel to the second rotation axis 32.

[0074] In this embodiment, the first rotation axis 31 is parallel to the second rotation axis 32, so that after the seat 2 is stored, the seat cushion 21 can fit as close as possible to the connecting structure 3, thereby reducing the space occupied by the stored seat 2 and the connecting structure 3.

[0075] It is understood that the first rotation axis 31 is not limited to being parallel to the second rotation axis 32. For example, the first rotation axis 31 is not parallel to the second rotation axis 32.

[0076] In some embodiments, please refer to Figures 3-7 The seat 2 is provided with connecting structures 3 on opposite sides along the lateral direction, which are arranged to intersect with the vertical and horizontal directions and the front and back directions respectively.

[0077] For example, horizontal refers to the left and right direction.

[0078] In this embodiment, the seat 2 is provided with connecting structures 3 on opposite sides along the lateral direction. The connecting structures 3 support the seat 2 on opposite sides along the lateral direction, thereby improving the stability of the seat 2.

[0079] It is understood that the seat 2 is not limited to having connecting structures 3 on opposite sides along the lateral direction. For example, the seat 2 has a connecting structure 3 on one side along the lateral direction.

[0080] In some embodiments, please refer to Figure 6 and Figure 7The connecting structure 3 includes a first segment 33, a second segment 34, and a third segment 35 connected in sequence. The first segment 33 is rotatably connected to the seat cushion 21 and rotates around the second rotation axis 32. The third segment 35 is rotatably connected to the chassis 11 and rotates around the first rotation axis 31. In the two connecting structures 3 located at both ends of the seat cushion 21 in the lateral direction, the second segment 34 at both ends and the third segment 35 at both ends are located between the first segments 33 at both ends in the lateral direction, and the third segment 35 at both ends is located between the second segments 34 at both ends in the lateral direction.

[0081] For example, the first segment 33, the second segment 34, and the third segment 35 are integrally formed.

[0082] In this embodiment, among the two connecting structures 3 located laterally at both ends of the seat cushion 21, the second segment 34 and the third segment 35 at both ends are located laterally between the first segment 33 at both ends, and the third segment 35 at both ends is located laterally between the second segment 34 at both ends. The end of the connecting structure 3 facing away from the first segment 33 is bent laterally towards the center of the seat cushion 21. The part where the chassis 11 rotates and connects to the third segment 35 has a large volume. The space between the second segments 34 on both sides is used to accommodate the part where the third segment 35 rotates and connects to the chassis 11. The storage cavity 111 does not need to reserve extra space on opposite sides laterally to accommodate and avoid the part where the third segment 35 rotates and connects to the chassis 11, thus improving the space utilization of the storage cavity 111. The fact that the end of the connecting structure 3 facing away from the first segment 33 is bent laterally towards the center of the seat cushion 21 increases the rigidity and strength of the connecting structure 3, thereby improving the safety collision performance of the seat 2.

[0083] It is understood that, in the two connecting structures 3 located laterally at both ends of the seat cushion 21, the second segment 34 and the third segment 35 at both ends are located between the first segment 33 at both ends, and the third segment 35 at both ends is located between the second segment 34 at both ends. For example, in the two connecting structures 3 located laterally at both ends of the seat cushion 21, when projected vertically, the projection area of ​​the first segment 33 coincides with the projection area of ​​the second segment 34, and the projection area of ​​the second segment 34 coincides with the projection area of ​​the third segment 35.

[0084] In some embodiments, please refer to Figures 2-5 When the seat 2 is in use, the thickness of the front side of the seat cushion 21 is greater than the thickness of the rear side of the seat cushion 21. The storage cavity 111 is formed in the trunk of the vehicle. The cavity wall on the lower side of the storage cavity 111 is the first wall 112. The first wall 112 is inclined, and the rear end of the first wall 112 is higher than the front end of the first wall 112.

[0085] For example, the storage cavity 111 is formed in the spare tire pit.

[0086] For example, please refer to Figure 2 The lowest position 72 of the first wall is located in front of the center line 71 of the rear wheel.

[0087] For example, please refer to Figure 2 The lowest position 72 of the first wall is located between the center line 71 of the rear wheel and the center line of the front wheel in the front-rear direction.

[0088] In this embodiment, when the seat 2 is in use, the thickness of the front side of the seat cushion 21 is greater than the thickness of the rear side, reducing the possibility that the user will slide towards the front of the seat cushion 21. Since the front side of the seat cushion 21 is thicker than the rear side, when the seat 2 is in a stowed state, the front end of the seat 2 is thicker than the rear end. This results in a larger vertical space required for the front end of the stowed cavity 111 and a smaller vertical space required for the rear end. The stowed cavity 111 is formed in the vehicle's trunk, making full use of the vehicle's existing space and reducing the occupation of external space. The lower wall of the stowed cavity 111 is a first wall 112, which is inclined. The rear end of the first wall 112 is higher than its front end. While ensuring that the vertical dimensions of the front and rear ends of the stowed cavity 111 meet the requirements for accommodating the seat 2, the rear end of the first wall 112 is further from the ground, increasing the vehicle's departure angle. The departure angle is the angle between the road surface and the tangent line drawn from the rearmost point of the vehicle body to the rear wheel when the vehicle is fully loaded and stationary.

[0089] It is understood that the first wall 112 is not limited to being inclined. For example, the first wall 112 is horizontal.

[0090] In some embodiments, please refer to Figure 6 and Figure 7 The connecting structure 3 has a protrusion 36, and the seat cushion 21 is rotatably connected to the protrusion 36. When the seat 2 is in use, the protrusion 36 protrudes towards the front end of the seat cushion 21 in the front-back direction. The second rotation axis 32 is located on the side of the protrusion 36 facing the front end of the seat cushion 21 in the front-back direction, and the front-back direction and the up-down direction are arranged intersectingly.

[0091] For example, the protrusion 36 is formed in the first segment 33.

[0092] In this embodiment, when the seat 2 is in use, the thickness of the front side of the cushion 21 is greater than the thickness of the rear side of the cushion 21. When the seat 2 is in use, the protrusion 36 protrudes towards the front end of the cushion 21 in the front-back direction. The second rotation axis 32 is located on the side of the protrusion 36 facing the front end of the cushion 21 in the front-back direction, so that the second rotation axis 32 is close to the front side of the cushion 21, so that there is enough space inside the cushion 21 in the up-down direction to set the part that is rotatably connected to the connecting structure 3.

[0093] It is understood that the second rotation axis 32 is not limited to the side of the protrusion 36 facing the front end of the seat cushion 21 in the front-rear direction. Exemplarily, the second rotation axis 32 is located on the side of the protrusion 36 facing the rear end of the seat cushion 21 in the front-rear direction.

[0094] In some embodiments, please refer to Figure 6 and Figure 7 The vehicle body 1 also includes a first locking part 12 connected to the chassis 11, and the seat 2 includes a second locking part 23. The second locking part 23 is disposed on the seat cushion 21. When the seat 2 is in use, the first locking part 12 can lock with the second locking part 23 to restrict the seat cushion 21 from rotating around the second rotation axis 32 and the connecting structure 3 from rotating around the first rotation axis 31.

[0095] For example, the first locking part 12 is a latch.

[0096] For example, the second locking part 23 is a locking ring.

[0097] For example, when the first locking part and the second locking part 23 are in the locked state, the seat 2 and the vehicle body 1 do not move relative to each other.

[0098] In this embodiment, the first locking part 12 is unlocked from the second locking part 23, the seat cushion 21 rotates around the second rotation axis 32 and the connecting structure 3 rotates around the first rotation axis 31. When the seat 2 is in use, the first locking part 12 can lock with the second locking part 23 to restrict the seat cushion 21 from rotating around the second rotation axis 32 and the connecting structure 3 from rotating around the first rotation axis 31, so that the seat cushion 21 and the connecting structure 3 will not rotate when the seat 2 is in use, thereby improving the safety of the seat 2.

[0099] It is understood that the vehicle body 1 may not have the first locking part 12, and the seat 2 may not have the second locking part 23. For example, when the seat 2 is in use, the seat cushion 21 is placed on the chassis 11.

[0100] In some embodiments, please refer to Figure 2 The vehicle also includes a drive unit 4 disposed on the vehicle body 1. The drive unit 4 includes a first drive unit and a second drive unit. The first drive unit is driven to connect to the connecting structure 3 to drive the connecting structure 3 to rotate around the first rotation axis 31 and / or drive the seat cushion 21 to rotate around the second rotation axis 32. The vehicle includes a rotating structure 5. The backrest 22 and the seat cushion 21 are respectively connected to the rotating structure 5. The second drive unit is driven to connect to the rotating structure 5 to drive the rotating structure 5 to drive the backrest 22 to rotate relative to the seat cushion 21.

[0101] For example, the first driving device includes a first driver, which is driven to connect to the connection structure 3 to drive the connection structure 3 to rotate about the first rotation axis 31.

[0102] For example, the first driving device includes a second driver, which is driven to be connected to the connection structure 3 to drive the seat cushion 21 to rotate about the second rotation axis 32.

[0103] For example, the first drive includes a motor.

[0104] For example, the second drive includes a motor.

[0105] For example, the second drive device includes a motor.

[0106] In this embodiment, the first driving device is driven to connect the connecting structure 3 to drive the connecting structure 3 to rotate around the first rotation axis 31 and / or drive the seat cushion 21 to rotate around the second rotation axis 32. The first driving device automatically drives the connecting structure 3 and / or the seat cushion 21 to rotate. The second driving device is driven to connect the rotating structure 5 to drive the rotating structure 5 to rotate the backrest 22 relative to the seat cushion 21. The second driving device automatically drives the seat 2 to fold, reducing manual operation by the user and improving the automation level of the vehicle.

[0107] It is understood that the vehicle may not be equipped with a drive unit 4. Exemplarily, the connecting structure 3 can be rotated about the first rotation axis 31 by manual operation of the user, the seat cushion 21 can be rotated about the second rotation axis 32 by manual operation of the user, and the backrest 22 can be rotated relative to the seat cushion 21 by manual operation of the user.

[0108] In some embodiments, please refer to Figure 1 and Figures 8-11 The number of seats 2 is at least two, and the at least two seats 2 are arranged laterally. The vehicle body 1 also includes at least one slide rail 13 connected to the chassis 11. The slide rail 13 extends in the front-rear direction. One of the slide rails 13 is a first slide rail 131. The first slide rail 131 and the storage cavity 111 are arranged laterally at intervals. One of the seats 2 is slidably disposed on the first slide rail 131. The front-rear direction and the vertical direction are arranged intersectingly. The lateral direction is arranged intersectingly with the front-rear direction and the vertical direction.

[0109] It should be noted that the seat 2, which is mounted on the first slide rail 131, is not rotatably connected to the connecting structure 3.

[0110] For example, the number of seats 2 is two, three, or four.

[0111] For example, the two seats 2 are a driver's seat 24 and a passenger seat 25, which are arranged laterally. Other seats 2 besides the driver's seat 24 and the passenger seat 25 are located behind the driver's seat 24.

[0112] For example, the rear passenger seat 27 located behind the front passenger seat 25 is slidably mounted on the first slide rail 131, and the rear driver seat 26 located behind the driver's seat 24 is rotatably connected to the connecting structure 3.

[0113] In this embodiment, the first slide rail 131 and the storage cavity 111 are arranged laterally at intervals. One of the seats 2 is slidably disposed on the first slide rail 131. One of the seats 2 can slide along the first slide rail 131 to one side of the storage cavity 111 along the lateral direction, changing the position of one of the seats 2 in the vehicle interior in the front-back direction, thereby improving the diversity of the interior space of the vehicle.

[0114] It is understood that one of the seats 2 is not limited to being slidably mounted on the first slide rail 131. Exemplarily, one of the seats 2 is fixedly connected to the chassis 11.

[0115] In some embodiments, please refer to Figures 8-11 The vehicle also includes at least one armrest box 61, and at least two slide rails 13, one of which is a second slide rail 132, which is located laterally between two adjacent seats 2, and at least one armrest box 61 is slidably disposed on the second slide rail 132.

[0116] For example, at least one armrest box 61 is a refrigerator.

[0117] For example, the second slide rail 132 is located laterally between the driver's seat 24 and the passenger seat 25.

[0118] For example, the armrest box 61 has a folding panel that can be unfolded vertically.

[0119] For example, the first slide rail 131 and the second slide rail 132 are arranged at a lateral interval.

[0120] In this embodiment, the second slide rail 132 is located laterally between two adjacent seats 2, and at least one armrest box 61 is slidably disposed on the second slide rail 132. The armrest box 61 can slide along the second slide rail 132 to change the position of the armrest box 61 in the front-back direction, thereby changing the interior space layout of the vehicle and creating a space for movement between the two adjacent seats 2, making it convenient for the user to move back and forth in the vehicle from the space between the two adjacent seats 2.

[0121] It is understood that at least one armrest box 61 is not limited to being slidably disposed on the second slide rail 132. Exemplarily, at least one armrest box 61 is fixedly connected to the chassis 11.

[0122] In some embodiments, please refer to Figures 8-11The number of armrest boxes 61 is at least two, and the at least two armrest boxes 61 are slidably disposed on the second slide rail 132 in the front-back direction.

[0123] For example, the number of armrest boxes 61 is two, three, or four.

[0124] In this embodiment, at least two armrest boxes 61 are slidably disposed on the second slide rail 132 in the front-to-back direction. At least two armrest boxes 61 are able to move in the front-to-back direction. The armrest boxes 61 can adapt to the position of the seat 2 after the movement. At least two armrest boxes 61 can simultaneously meet the usage needs of users in the front and rear seats 2.

[0125] It is understood that at least two armrest boxes 61 are not limited to being slidably disposed on the second slide rail 132 in the front-to-back direction respectively. Exemplarily, at least two armrest boxes 61 are fixedly connected to the chassis 11.

[0126] In some embodiments, please refer to Figures 11-13 The vehicle also includes a folding table 62, a slider 63, and a slide rail 64. The slide rail 64 is mounted on the chassis 11 and extends in the front-to-back direction. The seat 2, which is set on the first slide rail 131, is arranged in the front-to-back direction with the slide rail 64. The slider 63 is slidably mounted on the slide rail 64. The folding table 62 and the slider 63 are detachably connected. When the folding table 62 is in the unfolded state, it is mounted on the slider 63. When the folding table 62 is in the stowed state, it is separated from the slider 63.

[0127] For example, the folding table 62 can be stored under the passenger seat 25.

[0128] For example, the folding table 62 can be stored in the front trunk.

[0129] For example, the passenger seat 25 is rotatable relative to the chassis 11, and the rotation center line of the passenger seat 25 relative to the chassis 11 is parallel to the vertical direction.

[0130] For example, slide 64 is located behind the passenger seat 25.

[0131] For example, the slide rail 64 is located in the front-rear direction between the seat 2 and the front passenger seat 25, which are disposed on the first slide rail 131.

[0132] In this embodiment, the slider 63 is slidably disposed on the slide rail 64, and the folding table 62 is detachably connected to the slider 63. When the folding table 62 is in the unfolded state, the folding table 62 is mounted on the slider 63. When the folding table 62 is in the unfolded state, the slider 63 can drive the folding table 62 to move in the front-back direction, so that the folding table 62 adapts to the position of the seat 2 after sliding. When the folding table 62 is in the stowed state, the folding table 62 is separated from the slider 63. When the folding table 62 is in the stowed state, the folding table 62 will not interfere with the movement of the seat 2, increasing the diversity of the interior space layout of the vehicle.

[0133] It is understood that when the folding table 62 is in the unfolded state, the folding table 62 is not limited to being mounted on the slider 63. Exemplarily, the folding table 62 is placed on the chassis 11, and the folding table 62 can move in any direction inside the vehicle.

[0134] In some embodiments, please refer to Figure 1 and Figure 8 The vehicle also includes a cover 65. When the seat 2 is in the stowed state, the cover 65 covers the opening of the stowed cavity 111, and the seat 2 is located under the cover 65.

[0135] For example, when seat 2 is in the folded-out state, cover 65 covers the opening of the folding cavity 111, and cover 65 is horizontal.

[0136] For example, when the seat 2 is in use, the cover 65 is located inside the storage cavity 111.

[0137] In this embodiment, when seat 2 is in the stowed state, cover plate 65 covers the opening of the stowed cavity 111, and seat 2 is located below cover plate 65. Cover plate 65 covers the stowed seat 2, reducing the impact of the stowed seat 2 on the outside of the stowed cavity 111. Cover plate 65 can provide a relatively flat support surface, making it easier to use the space above the stowed cavity 111 to carry items and improving loading convenience.

[0138] Understandably, vehicles may be exempt from having a cover plate 65.

[0139] In some embodiments, please refer to Figure 9 The chassis 11 includes a support plate 113, at least three crossbeams 115 and at least four longitudinal beams 114. The crossbeams 115 and longitudinal beams 114 are respectively installed on the support plate 113. The longitudinal beams 114 extend in the front-rear direction. The at least four longitudinal beams 114 are spaced apart in the transverse direction. The crossbeams 115 extend in the transverse direction. The at least three crossbeams 115 are spaced apart in the front-rear direction. The crossbeams 115 are located in the transverse direction between two adjacent longitudinal beams 114. The storage cavity 111 is formed in the support plate 113.

[0140] For example, the upper surface of the crossbeam 115 is flush with the upper surface of the longitudinal beam 114.

[0141] For example, the crossbeam 115 and the longitudinal beam 114 are located below the support plate 113.

[0142] For example, the two outermost longitudinal beams 114 along the transverse direction are threshold beams, and the remaining longitudinal beams 114 are located between the two threshold beams.

[0143] For example, the crossbeams 115 and longitudinal beams 114 have the same cross-sectional dimensions, realizing the modularity, universality and platformization of the chassis 11. The number of crossbeams 115 and longitudinal beams 114 can be increased or decreased according to the size of the vehicle and performance requirements.

[0144] For example, the portion of the support plate 113 in front of the receiving cavity 111 is a flat plate.

[0145] In this embodiment, crossbeams 115 and longitudinal beams 114 are respectively installed on the support plate 113. The longitudinal beams 114 extend in the front-to-back direction, and at least four longitudinal beams 114 are spaced laterally. The crossbeams 115 extend laterally, and at least three crossbeams 115 are spaced laterally. The support plate 113 is structurally reinforced by the crossbeams 115 and longitudinal beams 114, improving the overall structural rigidity, strength, and durability of the chassis 11. The crossbeams 115 and longitudinal beams 114 can be positioned at the stress points of the support plate 113. While meeting the load-bearing requirements of the chassis 11, the thickness of the support plate 113 can be reduced, and the flatness of the support plate 113 can be improved. This provides sufficient space above the support plate 113 for the seat 2 to move, reducing the difficulty of changing the interior space layout and maximizing the passenger compartment space.

[0146] In some embodiments, when the seat 2 is in use, the first rotation axis 31 and the second rotation axis 32 can move closer to or further away from each other in the front-back direction.

[0147] In one embodiment, when the seat 2 is in use, the connecting structure 3 can extend and retract in the front-to-back direction.

[0148] In some embodiments, the seat 2, which is rotatably connected to the connecting structure 3, includes a telescopic member. The seat cushion 21 is connected to one end of the telescopic member, and the other end of the telescopic member is rotatably connected to the connecting structure 3. One of the slide rails 13 is a third slide rail 133, which is located on the front side of the connecting structure 3. When the seat 2 is in use, the seat cushion 21 is slidably disposed on the third slide rail 133. The telescopic member extends and retracts to drive the seat cushion 21 to move along the third slide rail 133.

[0149] In some embodiments, please refer to Figures 3-5The rear passenger seat 27 is rotatably connected to the connecting structure 3. The rear passenger seat 27 is not equipped with a sliding rail 13, and the connecting structure 3 cannot extend or retract. When the rear passenger seat 27 is in use, the rear passenger seat 27 is locked to the chassis 11. In the locked state, the rear passenger seat 27 and the chassis 11 have no relative movement.

[0150] In some embodiments, the vehicle includes a combination table 66. When the seat 2 is located in the storage cavity 111, the combination table 66 can be placed above the storage cavity 111, and the seat 2, which is mounted on the first slide rail 131, can be moved to one side of the combination table 66 in the lateral direction.

[0151] For example, the combination table 66 can be stored in the front trunk.

[0152] This application provides a vehicle control method, applied to a vehicle, the control method including: The control connection structure rotates relative to the chassis so that the seat can be stored in the storage cavity.

[0153] For example, before controlling the connection structure 3 to rotate relative to the chassis 11, the control method further includes controlling the backrest 22 to rotate relative to the seat cushion 21.

[0154] For example, after controlling the connection structure 3 to rotate relative to the chassis 11, the control method further includes controlling the seat cushion 21 to rotate relative to the connection structure 3.

[0155] In this embodiment, the control connection structure 3 rotates relative to the chassis 11 so that the seat 2 is stored in the storage cavity 111. The automatic control of the connection structure 3 to rotate relative to the chassis 11 so that the seat 2 is stored in the storage cavity 111 realizes the change of the vehicle's interior space layout and improves the vehicle's automation level.

[0156] In some embodiments, the vehicle includes at least two seats 2 and an armrest box 61, wherein one of the seats 2 is rotatably connected to the connecting structure 3, and at least one of the other seats 2 is movably disposed on the chassis 11, and the armrest box 61 is movably disposed on the chassis 11; The control method for controlling the rotation of the connection structure relative to the chassis so that the seat is retracted into the storage cavity also includes: Control the movement of one of the seats and the armrest box.

[0157] It should be noted that the movable seat 2 is not the same seat 2 stored in the storage cavity 111.

[0158] In this embodiment, controlling the movement of one of the seats 2 and the armrest box 61 automatically controls the movement of the seat 2 and the armrest box 61, thus automatically controlling the change in the interior space layout and improving the vehicle's automation level. Controlling the rotation of the connecting structure 3 relative to the chassis 11 allows the seat 2 to be stored in the storage cavity 111. After one of the seats 2 is stored in the storage cavity 111, the space of the passenger compartment inside the vehicle increases. Controlling the movement of the other seat 2 and the armrest box 61 reduces interference with the movement of the seat 2 and the armrest box 61.

[0159] It is understood that, not limited to, controlling the rotation of the connecting structure 3 relative to the chassis 11 to allow the seat 2 to be stored in the storage cavity 111, the movement of one of the seats 2 and the movement of the armrest box 61 are controlled. Exemplarily, the movement of one of the seats 2 is controlled before the connecting structure 3 is rotated relative to the chassis 11 to allow the seat 2 to be stored in the storage cavity 111.

Through various scene transformation models set in the central computer system by software, it can be coordinated with the layout of the seat 2 to realize the unfolding of a coffee table or desk.

[0166] In one embodiment, the driver or passenger issues a command via VUI (vehicle information unit), which may be displayed as the text "fold up the rear seat (left)" or spoken as "fold up the rear left seat" or an icon showing the rear left seat 2 in a folded state, thus hiding the driver's rear left seat 2 to provide more space.

[0167] In some embodiments, the vehicle of this application transforms the limited interior space into a multi-scenario application combination, and can be perfectly integrated with the new energy vehicle electrical platform. By utilizing the central computing platform software and the electric hardware in the vehicle, several arrangements of in-vehicle equipment in three-dimensional space can be realized, and common scenarios such as one-click space maximization, one-click space heightening and widthening can be achieved, thus solving the problems of limited interior space, homogeneous layout, and limited space utilization.
