Description

Technical Field

[0001] This application relates to the field of vehicle seat technology, and more particularly to a seat structure and a vehicle. Background Technology

[0002] As the demand for vehicle ride comfort gradually increases, more and more models are equipping their second-row seats with zero-gravity seats. When adjusting a zero-gravity seat from a sitting to a reclining position, a large amount of interior space is usually required. The side and rear of the second-row seats are usually the rear wheel arches that protrude inwards towards the vehicle body. The third-row armrests are usually located above the rear wheel arches, which makes it easy for the third-row armrests to interfere with the adjustment of the second-row seats from a sitting to a reclining position.

[0003] In related technologies, to ensure smooth adjustment of the second-row seats, a lateral sliding rail is typically installed at the bottom of the second-row seats. When the second-row seats need to be adjusted from a sitting to a reclining position, they must first be moved laterally inward along the lateral sliding rail a certain distance to avoid the third-row armrests on the side and rear before the seatbacks are unfolded. This method not only makes the adjustment process for the second-row seats more complicated and time-consuming, affecting the riding experience of second-row passengers, but also increases the distance between the second-row seats and the inner door armrests after the second-row seats are moved inward, thus affecting the use of the door armrests by second-row passengers. Utility Model Content

[0004] This application provides a seat structure and vehicle that optimizes the adjustment space of the second-row seats and improves the riding experience by adjusting the third-row armrests of the three-row seats to a foldable form. This ensures that the third-row armrests do not affect the posture adjustment of the second-row seats.

[0005] The first aspect of this application provides a seat structure including a second row of seats and a third row of seats arranged sequentially along the length of the vehicle. The second row of seats are adjustable seats, capable of being adjusted between a sitting position and a reclining position; for example, the second row of seats can be zero-gravity seats. The third row of seats includes third-row armrests, which are disposed on both sides of the third row of seats and can switch between an unfolded state and a folded state relative to the third row of seats.

[0006] In the seat structure of this application embodiment, when the second-row seats are unfolded and adjusted to a reclining position, the third-row armrests are switched to a folded state. This avoids interference between the third-row armrests and the adjustment of the second-row seats, optimizing the adjustable space of the second-row seats. Simultaneously, when passengers are seated in the third-row seats, the third-row armrests can be switched to an unfolded state without affecting the seating comfort of the third-row seats. Compared to the solution of moving the second-row seats laterally before adjusting them to a reclining position, this application only requires the third-row armrests to simultaneously switch states in coordination with the adjustment of the second-row seats, saving adjustment time and simplifying the adjustment steps.

[0007] In some embodiments, the third-row armrests are connected to the vehicle body structure on both sides of the third-row seats; or the third-row armrests are connected to the seatbacks of the third-row seats. This application does not limit the specific installation position of the third-row armrests relative to the sides of the third-row seats, as long as the third-row armrests can switch between an unfolded and folded state. When the third-row armrests are in the unfolded state, they can support the arms and improve the seating comfort of the third-row seats; when the third-row armrests are in the folded state, they can avoid interfering with the adjustment of the second-row seats.

[0008] In some implementations, the third-row armrests are folded down when the second-row seats are adjusted from a sitting to a reclining position. This folding down of the third-row armrests optimizes the adjustable space of the second-row seats and prevents them from interfering with the reclining adjustment.

[0009] In some implementations, when the second-row seats are adjusted from a reclining position to a sitting position, the third-row armrests are in the extended position. This allows passengers in the third row to rest their arms directly on the third-row armrests without needing to adjust the seating position again.

[0010] In some embodiments, the three-row armrest includes a first end and a second end disposed opposite to the first end. The first end is provided with a rotating mechanism, which drives the second end to rotate relative to the three-row seats with the first end as the rotation axis.

[0011] In this way, the third-row armrests can be rotated between the unfolded and folded states via a rotating mechanism. When the second end rotates away from the second-row seats with the first end as the axis of rotation, it can provide sufficient space for the adjustment of the second-row seats and avoid the second end interfering with the adjustment of the second-row seats to a reclining position.

[0012] In some embodiments, the three rows of seats also include seat backs, and the body structure on both sides of the three rows of seats is provided with a bearing surface and an inclined surface. The bearing surface is used to support the three rows of armrests, and the inclined surface extends inclinedly along the bearing surface towards the side of the seat back.

[0013] When the three rows of handrails are in the unfolded state, the lower surface of the three rows of handrails is in contact with the bearing surface; when the three rows of handrails are in the folded state, the upper surface of the three rows of handrails is in contact with the inclined surface.

[0014] In this way, the three rows of handrails can restrict the rotation position of the three rows of handrails through the bearing surface and the inclined surface, so as to avoid the rotation angle being too large and affecting the use of the three rows of handrails; at the same time, when the three rows of handrails rotate to fit with the bearing surface, the bearing surface can still support the three rows of handrails, making the bearing capacity of the three rows of handrails stronger and preventing damage due to excessive force.

[0015] In some embodiments, the inclined surface is provided with a folding groove, which is recessed in a direction perpendicular to the inclined surface. When the three rows of armrests are in the folded state, the upper surface of the three rows of armrests fits against the bottom of the folding groove. In this way, the folding groove can be used to hide the three rows of armrests when they are folded, improving the aesthetics of the interior structure when folded.

[0016] In some embodiments, the third-row armrests are provided with a translation mechanism, which is used to move the third-row armrests towards the second-row seats or away from the second-row seats; when the third-row armrests are close to the second-row seats, the third-row armrests are in an unfolded state; when the third-row armrests are away from the second-row seats, the third-row armrests are in a folded state.

[0017] In this way, the third-row armrests can be switched between unfolded and folded states via a sliding mechanism. Driven by the sliding mechanism, the third-row armrests move away from the second-row seats, thus providing ample space for the adjustment of the second-row seats and preventing the third-row armrests from interfering with the adjustment of the second-row seats to a reclining position.

[0018] In some implementations, the vehicle body structure on both sides of the three rows of seats has a bearing surface for supporting the three rows of armrests, which are then moved horizontally above the bearing surface.

[0019] In this way, the three rows of handrails can be moved horizontally on the bearing surface, which can support the three rows of handrails, making the three rows of handrails stronger and preventing them from being damaged due to excessive force.

[0020] In some implementations, the armrests of the third row remain extended when all three rows of seats are occupied. This allows passengers in the third row to keep their arms resting on the armrests, improving the comfort of the seating area.

[0021] In some implementations, the three-row armrest includes a cup holder and a recess for concealing the cup holder, which can be hidden within the recess and can switch between an extended and concealed state relative to the three-row armrest.

[0022] In this way, the cup holders on the third-row armrests can be used to hold cups, making it convenient for third-row passengers. The recess can hide the cup holders, which optimizes the adjustment space of the second-row seats and also prevents the cup holders from interfering when the third-row armrests are folded, making it easier for the third-row armrests to fold.

[0023] In some implementations, the three rows of armrests remain extended when the cup holders are in the extended and in use position.

[0024] In this way, when there is a cup in the cup holder, the three rows of armrests will remain in the unfolded state to avoid knocking over the cup and polluting the car interior. Only when there is no cup in the cup holder can the three rows of armrests switch from the unfolded state to the folded state.

[0025] In some implementations, the second-row seats remain seated while the third-row armrests are extended. Specifically, when passengers are seated in the third row, maintaining the extended armrests and the seated second row avoids obstructing their seating. Similarly, when the cup holders are in use, maintaining the extended armrests and the seated second row prevents them from scratching or bumping against the extended cup holders.

[0026] A second aspect of this application provides a vehicle, which includes a body structure and a seating structure as described in any of the above embodiments, wherein the second-row seats and the third-row seats in the seating structure are located inside the body structure.

[0027] In the vehicle of this application embodiment, foldable third-row armrests are provided on both sides of the third-row seats. When the second-row seats are adjusted, the third-row armrests are folded down, so that the second-row seats can have more adjustment space and avoid the third-row armrests interfering with the posture adjustment of the second-row seats. At the same time, there is a control logic between the posture adjustment of the second-row seats and the state switching of the third-row armrests, so that the adjustment of the second-row seats is smoother and the folding of the third-row armrests and the adjustment of the second-row seats do not affect each other.

[0028] In some implementations, the second-row seats also include second-row armrests and extended armrests, both of which are mounted on the vehicle structure on both sides of the second-row seats. Along the extension direction of the second-row armrests, the extended armrests extend towards the third-row seats. When the second-row seats are adjusted to a reclining position, the extended armrests can support the arms.

[0029] In this way, when the second-row seats are in a sitting position, second-row passengers can rest their arms on the second-row armrests inside the doors. When the second-row seats are in a reclining position, second-row passengers can move their bodies back and rest their arms on the extended armrests, improving the riding experience for second-row passengers.

[0036] As the demand for vehicle ride comfort gradually increases, more and more models are equipping their second-row seats with zero-gravity seats. When adjusting a zero-gravity seat from a sitting position to a reclining position, a large amount of interior space is usually required. The rear side of the second-row seats is usually the rear wheel hump that protrudes inwards towards the vehicle body, and the third-row armrests are usually located above the rear wheel hump. As a result, when the second-row seats are adjusted backwards, they are easily interfered with by the rear wheel hump and the third-row armrests.

[0037] In related technologies, to ensure smooth adjustment of the second-row seats, a lateral sliding rail is typically installed at the bottom of the second-row seats. When the second-row seats need to be adjusted from a sitting to a reclining position, they must first be moved laterally inward along the lateral sliding rail a certain distance to avoid the third-row armrests before the seatbacks are unfolded. This method not only makes the adjustment process for the second-row seats more complicated and time-consuming, affecting the riding experience of second-row passengers, but also increases the distance between the second-row seats and the inner door armrests after the second-row seats are moved inward, thus affecting the use of the door armrests by second-row passengers.

[0038] Therefore, embodiments of this application provide a seat structure 100 and a vehicle 200 to solve the above-mentioned problems. Please refer to... Figures 1-6 , Figure 1 This is a schematic diagram of vehicle 200. Figure 2 This is a schematic diagram of seat structure 100. Figure 3 This is a schematic diagram showing the unfolded state of the three rows of armrests 21 when they rotate and switch. Figure 4 This is a schematic diagram showing the folded state of the three rows of armrests 21 when they rotate and switch. Figure 5 This is a schematic diagram showing the unfolded state of the three rows of armrests 21 during the sliding transition. Figure 6 This is a schematic diagram of the folded state of the three rows of handrails 21 during the sliding and switching process.

[0039] The vehicle 200 provided in this application embodiment includes a body structure 210 and a seat structure 100 as described in this application embodiment. The seat structure 100 includes a second-row seat 10 and a third-row seat 20 arranged sequentially along the length of the vehicle 200. Both the second-row seat 10 and the third-row seat 20 are located inside the body structure 210. The second-row seat 10 is an adjustable seat, capable of being adjusted between a sitting and a reclining position; for example, the second-row seat 10 can be a zero-gravity seat. The third-row seat 20 includes third-row armrests 21, which are located on both sides of the third-row seat 20 and can switch between an unfolded and folded state relative to the third-row seat 20.

[0040] In the seat structure 100 and vehicle 200 of this application embodiment, when the second-row seat 10 is unfolded and adjusted to a reclining position, the third-row armrest 21 of the third-row seat 20 is switched to a folded state. This avoids the third-row armrest 21 interfering with the adjustment of the second-row seat 10, optimizing the adjustable space of the second-row seat 10. Simultaneously, when passengers are seated in the third-row seat 20, the third-row armrest 21 can also be switched to an unfolded state without affecting the seating comfort of the third-row seat 20. Compared to the solution of moving the second-row seat 10 laterally before adjusting it to a reclining position, this application only requires the third-row armrest 21 to simultaneously switch states in coordination with the adjustment of the second-row seat 10, saving adjustment time and simplifying the adjustment steps.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the second-row seats 10 can be positioned in the middle of the vehicle 200, with two independent second-row seats 10 spaced apart along the width of the vehicle body. The second-row seats 10 are adjustable seats; "adjustable" can include overall fore-and-aft adjustment, backrest angle adjustment, etc. For example, the second-row seats 10 can include zero-gravity seats, airline seats, and other comfortable seats capable of large-angle adjustment. Specifically, the reclining position allows the backrest of the second-row seat 10 to be adjusted backward, enabling second-row passengers to lie down; the sitting position allows the backrest of the second-row seat 10 to be upright relative to the seat cushion, allowing second-row passengers to sit up. It should be noted that the second-row seats 10 can not only be adjusted between reclining and sitting positions, but the backrest of the second-row seat 10 can also be adjusted to any comfortable angle relative to the seat cushion.

[0042] The third row of seats 20 can be located behind the second row of seats 10 in the vehicle 200. Along the width of the vehicle body, the third row of seats 20 can be two separate independent seats or a single strip seat. Third row of armrests 21 are provided on both sides of the third row of seats 20.

[0043] The third-row armrest 21 can be located above the rear wheel arch and connected to the body structure 210 on both sides, or it can be located on the side of the third-row seat 20 and connected to the seat back of the third-row seat 20. This application does not limit the specific installation position of the third-row armrest 21 relative to the third-row seat 20, as long as the third-row armrest 21 can switch between an unfolded state and a folded state. When the third-row armrest 21 is in the unfolded state, it can be used to support the arm and improve the seating comfort of the third-row seat 20. When the third-row armrest 21 is in the folded state, it can avoid interfering with the adjustment of the second-row seat 10.

[0044] The third-row armrests 21 can switch between an unfolded state and a folded state relative to the third-row seats 20. In the unfolded state, the third-row armrests 21 are positioned horizontally on both sides of the third-row seats 20, allowing passengers in the third row to rest their arms on them. In the folded state, the third-row armrests 21 are retracted relative to the third-row seats 20, preventing passengers in the third row from resting their arms on them. It should be noted that the switching between the unfolded and folded states can include not only rotational switching but also sliding switching and other methods.

[0045] When the backrest of the second-row seat 10 is adjusted to a large angle, switching the third-row armrest 21 to the folded state will increase the adjustment space of the backrest of the second-row seat 10 and avoid affecting the adjustment of the second-row seat 10. When the second-row seat 10 returns to the sitting position and there are people sitting in the third-row seat 20, switching the third-row armrest 21 to the unfolded state will not affect the seating comfort of the third-row passengers.

[0046] like Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, when the second-row seat 10 is adjusted from a sitting position to a reclining position, the third-row armrest 21 is folded down. Thus, switching the third-row armrest 21 to the folded state optimizes the adjustable space of the second-row seat 10 and prevents the third-row armrest 21 from interfering with the adjustment of the second-row seat 10 to a reclining position.

[0047] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, when the second-row seat 10 is adjusted from a reclining position to a sitting position, the third-row armrest 21 is in the unfolded state. Thus, when someone is seated in the third-row seat 20, they can directly rest their arms on the third-row armrest 21 without further adjustment.

[0048] Please see Figures 2-4 In some embodiments, the third-row armrest 21 includes a first end 22 and a second end 23 disposed opposite to the first end 22. The first end 22 is provided with a rotating mechanism 24, which can drive the second end 23 to rotate relative to the third-row seat 20 with the first end 22 as the rotation axis.

[0049] In this way, the third-row armrest 21 can be rotated between the unfolded state and the folded state through the rotating mechanism 24. When the second end 23 rotates away from the second-row seat 10 with the first end 22 as the rotation axis, it can provide sufficient space for the adjustment of the second-row seat 10 and avoid the second end 23 interfering with the adjustment of the second-row seat 10 to the reclining position.

[0050] Specifically, the rotating mechanism 24 may include a drive motor and transmission components, such as a brushless motor or a linear motor. The rotating mechanism 24 may be hidden inside the first end 22 of the third-row armrest 21 and extend from one side of the first end 22. The third-row armrest 21 can be directly connected to the backrest of the third-row seat 20 or the body structure 210 through the drive motor to achieve state switching, or it can be indirectly connected through transmission components such as gears and lead screws to achieve rotation. This application does not limit the specific structure of the rotating mechanism 24, as long as the rotating mechanism 24 can automatically drive the third-row armrest 21 to switch states.

[0051] In some embodiments, the three-row seats 20 also include a seat cushion and a backrest. The body structure 210 on both sides of the three-row seats 20 is provided with a bearing surface 211 and an inclined surface 212. The bearing surface 211 can be arranged parallel to the seat cushion. The bearing surface 211 is used to support the three-row armrests 21. The inclined surface 212 extends inclinedly along the bearing surface 211 towards the side closer to the backrest.

[0052] When the three-row handrail 21 is in the unfolded state, the lower surface of the three-row handrail 21 is in contact with the bearing surface 211; when the three-row handrail 21 is in the folded state, the upper surface of the three-row handrail 21 is in contact with the inclined surface 212.

[0053] In this way, the three-row handrail 21 can restrict the rotation position of the three-row handrail 21 through the bearing surface 211 and the inclined surface 212, so as to avoid the rotation angle being too large and affecting the use of the three-row handrail 21; at the same time, when the three-row handrail 21 rotates to fit with the bearing surface 211, the bearing surface 211 can also support the three-row handrail 21, making the bearing capacity of the three-row handrail 21 stronger and avoiding damage due to excessive force.

[0054] Specifically, the vehicle body structure 210 may include the interior structure of the vehicle 200, and the load-bearing surface 211 and the inclined surface 212 may be the surfaces of the interior structure. The load-bearing surface 211 may be arranged parallel to the seat cushions of the third-row seats 20, and the inclined surface 212 may be arranged parallel to the backrests of the third-row seats 20. Of course, the load-bearing surface 211 and the inclined surface 212 may also be adjusted according to the actual situation of the vehicle body structure 210, as long as the third-row armrests 21 have suitable rotation space and load-bearing capacity. This application does not impose specific limitations in this regard.

[0055] Please see Figure 3 and Figure 4In some embodiments, the inclined surface 212 is provided with a folding groove 28, which is recessed in a direction perpendicular to the inclined surface 212. When the third-row armrests 21 are in the folded state, the upper surface of the third-row armrests 21 fits against the bottom of the folding groove 28. Thus, the folding groove 28 can be used to hide the third-row armrests 21 when they are folded, improving the aesthetics of the interior structure when folded. The shape of the folding groove 28 can be adapted to the shape of the third-row armrests 21, so that the third-row armrests 21 can be hidden in the folding groove 28 when folded, avoiding the third-row armrests 21 occupying the space of the side body structure 210 after folding, and affecting the space on both sides of the third-row seats 20.

[0056] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the third-row armrest 21 is provided with a translation mechanism 25, which is used to move the third-row armrest 21 towards the second-row seats 10 or away from the second-row seats 10. When the third-row armrest 21 is close to the second-row seats 10, the third-row armrest 21 is in an unfolded state; when the third-row armrest 21 is away from the second-row seats 10, the third-row armrest 21 is in a folded state.

[0057] In this way, the third-row armrest 21 can be moved between the unfolded state and the folded state through the translation mechanism 25. Driven by the translation mechanism 25, the third-row armrest 21 moves away from the second-row seat 10, which can provide sufficient space for the adjustment of the second-row seat 10 and avoid the third-row armrest 21 interfering with the adjustment of the second-row seat 10 to the reclining position.

[0058] Specifically, the translation mechanism 25 may include a drive motor and transmission components. The drive motor may be a brushless motor, a linear motor, etc. The translation mechanism 25 may be located inside the third-row armrest 21 and at least partially extend out of the third-row armrest 21 to connect with the vehicle body structure 210 or the seat back. Alternatively, the translation mechanism 25 may be located inside the vehicle body structure 210 or the seat back and at least partially extend out of the vehicle body structure 210 or the seat back to connect with the third-row armrest 21. This application does not limit the installation position of the translation mechanism 25. The translation mechanism 25 can drive the third-row armrest 21 to translate relative to the third-row seats 20 to switch between an unfolded state and a folded state.

[0059] In some embodiments, the third-row seats 20 also include seat cushions, and the body structure 210 on both sides of the third-row seats 20 is provided with a bearing surface 211. The bearing surface 211 can be arranged parallel to the seat cushion. The bearing surface 211 is used to support the third-row armrests 21, and the third-row armrests 21 can be moved horizontally above the bearing surface 211.

[0060] In this way, the three rows of handrails 21 can be moved horizontally on the bearing surface 211, which can support the three rows of handrails 21, making the bearing capacity of the three rows of handrails 21 stronger and avoiding damage due to excessive force.

[0061] Specifically, the vehicle body structure 210 may include the interior structure of the vehicle 200, and the load-bearing surface 211 may be the surface of the interior structure. The load-bearing surface 211 may be arranged parallel to the seat cushions of the third row of seats 20. Of course, the load-bearing surface 211 may also be adjusted according to the actual situation of the vehicle body structure 210, as long as it can ensure that the third row armrests 21 can be translated along the extension direction of the load-bearing surface 211 and have good load-bearing capacity. This application does not impose specific restrictions on this.

[0062] In some implementations, the third-row armrests 21 remain extended when the third-row seats 20 are occupied. This allows passengers in the third row to keep their arms resting on the armrests 21, improving the comfort of the third-row seats 20. Of course, when the third-row seats 20 are unoccupied, the armrests 21 can be folded down, allowing the second-row seats 10 to be adjusted freely without affecting their posture.

[0063] Please see Figure 3 and Figure 4 In some embodiments, the three-row armrest 21 includes a cup holder 26 and a groove 27 for concealing the cup holder 26. The cup holder 26 can be concealed within the groove 27 and can switch between an extended state and a concealed state relative to the three-row armrest 21.

[0064] Thus, when the cup holder 26 on the third-row armrest 21 is pulled out, it can be used to hold cups, making it convenient for third-row passengers to use; when the cup holder 26 is hidden, the groove 27 can hide the cup holder 26. When the cup holder 26 is hidden, it can optimize the adjustment space of the second-row seat 10, and at the same time, it can also avoid interference from the cup holder 26 when the third-row armrest 21 is folded, making it convenient for the third-row armrest 21 to fold.

[0065] In some implementations, the third-row armrest 21 remains in the extended state when the cup holder 26 is in the extended and in use state. Thus, when there is a cup in the cup holder 26, the third-row armrest 21 will remain in the extended state to avoid knocking over the cup in the cup holder 26 and contaminating the interior environment of the vehicle. Only when there is no cup in the cup holder 26 can the third-row armrest 21 switch from the extended state to the folded state.

[0066] In some embodiments, the second-row seats 10 remain in a seated position while the third-row armrests 21 remain extended. The extension of the third-row armrests 21 can include various situations. For example, when passengers are seated in the third-row seats 20, keeping the third-row armrests 21 extended and the second-row seats 10 in a seated position can avoid affecting the seating of passengers in the third row; when the cup holders 26 are in use, keeping the third-row armrests 21 extended and the second-row seats 10 in a seated position can prevent them from scratching or bumping against the extended cup holders 26.

[0067] Please see Figure 1 In some embodiments, the second-row seat 10 also includes a second-row armrest 11 and an extended armrest 12. The second-row armrest 11 and the extended armrest 12 are both provided on the body structure 210 on both sides of the second-row seat 10. Along the extension direction of the second-row armrest 11, the extended armrest 12 extends towards the third-row seat 20. When the second-row seat 10 is adjusted to a reclining position, the extended armrest 12 can support the arm.

[0068] Thus, when the second-row seats 10 are in a sitting position, passengers in the second-row seats 10 can rest their arms on the second-row armrests 11. When the second-row seats 10 are in a reclining position, passengers in the second-row seats 10 can move their bodies back and rest their arms on the extended armrests 12, thus improving the riding experience of the second-row passengers.

[0069] In summary, in the seat structure 100 and vehicle 200 of this application embodiment, by setting the third-row armrests 21 on both sides of the third-row seats 20 as foldable armrests, the second-row seats 10 do not need to be moved laterally before being adjusted forward and backward, thus optimizing the adjustment steps of the second-row seats 10 and saving adjustment time. At the same time, control logic is added between the posture adjustment of the second-row seats 10 and the switching of the armrests of the third-row seats 20, avoiding the situation where the third-row armrests 21 interfere with the adjustment of the second-row seats 10, and also avoiding the situation where the third-row armrests 21 knock over water cups or other items on the armrests when folded, thus optimizing the passenger riding experience.
