Seat and terminal

Abstract

A seat and a terminal, applied in the technical field of seat fittings. The seat comprises side panels. Each side panel comprises a first side panel and a second side panel, the first side panel being slidably connected to the second side panel; in a first direction, the first side panel and the second side panel can move close to or move away from each other; and the first direction is a direction from the rear side to the front side of the seat. In the present application, each side panel uses a split design, and when the seat is folded, the first side panel and the second side panel in the side panel are away from each other, such that an accommodating space capable of accommodating a corresponding side wing of a backrest is formed between the first side panel and the second side panel, thereby solving the problem that side panels prevent a backrest from being folded forward because side wings of the backrest heavily interfere with the side panels when a seat is folded.

Description

A seat and a terminal

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 25, 2023, with application number 202323572854.0, and priority to the Chinese patent application entitled "A Chair and Terminal", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of seat accessories, and in particular to a seat and a terminal. Background Art

[0003] In passenger vehicles, the position and posture of seats can be adjusted to enhance the ride experience. Generally speaking, seats can be deployed or folded, with different positions providing different benefits. For example, folding the rear seats can provide more cargo space, or folding the front seats allows the front and rear seats to connect, creating more room for rear passengers. In two-door, four-seat vehicles, where space is often congested, folding the front seats can provide access to the rear seats.

[0004] However, the current folding function of seats is not ideal. To provide passengers with a sense of envelopment and lumbar support, current automotive seat backs are often designed with more ergonomic shapes. For example, forward projections are provided at the lumbar support to support the passenger's waist, and side wings or wing-like projections extend from both sides of the seat back to provide a more enveloping seat. However, when the seat is tilted forward and folded, these designs that provide a more supportive and enveloping feeling for the passenger interfere significantly with the side panels on both sides of the seat. These side panels can hinder the forward tilt of the seat back, preventing the seat from fully folding flat.

[0005] Summary of the Invention

[0006] The present application provides a seat and a terminal, which can prevent the side panels from hindering the seat back from flipping forward, thereby increasing the foldable angle of the seat.

[0007] In a first aspect, the present application provides a seat, comprising side panels, the side panels comprising a first side panel and a second side panel, the first side panel matching the second side panel, and being able to move closer to or further away from each other along a first direction. The first direction is the direction from the back side to the front side of the seat. Through the above arrangement, when the first side panel and the second side panel move away from each other, the second side panel can free up a portion of space on the back side of the seat panel after moving away from the first side panel along the first direction. This space can accommodate the waist of the seat back when the backrest is folded, preventing the side panels from hindering the seat back from flipping forward, increasing the foldable angle of the seat, thereby reducing the flat angle of the seat, increasing the available space, and allowing the seat to have more possibilities when in use. Furthermore, increasing the foldable angle of the seat can further reduce the minimum occupied volume of the seat, reducing the costs of packaging, warehousing, transportation, and installation of the seat.

[0008] Furthermore, the present application combines two separately provided side panels to form the side panel, allowing the side panel to be manufactured by separately processing two smaller side panels and then combining them, rather than directly processing a larger module as a whole. This reduces the cost of manufacturing the side panel module. In some solutions, especially when buttons, decorative strips, etc. need to be designed on the side panel, the two separately provided side panels provide more flexible design space and processing space without affecting the assembly surface of the two side panels, helping to reduce the complexity of seat design and processing.

[0009] Here, matching can be understood as the contact parts of the first side panel and the second side panel being matched. When the seat is unfolded, the first side panel and the second side panel can be spliced ​​into a whole. When the seat is folded, the first side panel and the second side panel can be separated into two parts. In some embodiments, there is a connection relationship between the first side panel and the second side panel. Exemplarily, the connection relationship between the first side panel and the second side panel includes a detachable connection. The detachable connection includes but is not limited to: the first side panel and the second side panel are connected using fasteners or are slidably connected through a sliding mechanism. The connection relationship here can be a direct connection or an indirect connection. In other embodiments, there is no connection relationship between the first side panel and the second side panel, and they are only formed into a whole by splicing.

[0010] In one possible embodiment of the first aspect, the first side panel is provided with a first accommodating portion. When the seat is in the unfolded state, at least a portion of the second side panel is accommodated in the first accommodating portion. When the seat is in the folded state, at least a portion of the second side panel is detached from the first accommodating portion. The first accommodating portion can also be used to accommodate the seat backrest and / or seat backrest components, such as the side wings of the seat backrest, to avoid interference when the seat is folded and to ensure that the side panels of the seat mate together as a whole when close together, thereby shielding the internal frame and side foam of the seat and improving the aesthetics of the seat.

[0011] In another possible embodiment of the first aspect, the first side panel is further provided with a second accommodating portion, and the first accommodating portion and the second accommodating portion are arranged in sequence along the first direction. Along the second direction, the depth of the second accommodating portion is greater than the depth of the first accommodating portion. The second direction is the direction from top to bottom of the seat, and when the seat is in a folded state, at least part of the second side panel is accommodated in the second accommodating portion. The depth of the second accommodating portion is greater than the depth of the first accommodating portion, so that the position of the second accommodating portion is lower than the first accommodating portion. At this time, the second side panel can move forward and downward, reserving more space for the seat back, thereby achieving non-interference between the seat back and the seat. In addition, the movement in two directions also allows the two side panels to be matched into a whole after moving away from each other, shielding the internal frame and side foaming of the seat, thereby improving the aesthetics of the seat.

[0012] In another possible implementation of the first aspect, the seat further includes a seat body, and the side panel is provided on one side of the seat body.

[0013] The seat body comprises a first body and a second body, the first body and the second body being slidably connected. Along a first direction, the first and second bodies can move closer to or farther from each other. The first side panel is fixedly connected to the first body, and the second side panel is fixedly connected to the second body. This allows the second body to drive the movement of the second side panel, increasing the foldable angle of the seat and leaving more space for the seat backrest.

[0014] In another possible embodiment of the first aspect, the chair further includes a cushion and a backrest. The backrest is rotatably connected to the first body, and the cushion is fixedly connected to the second body. When the first body and the second body move toward or away from each other, the cushion and the second body move together.

[0015] In another possible implementation of the first aspect, the first body is provided with a slide mechanism, and the second body is provided with a slide rail. Alternatively, the first body is provided with a slide rail, and the second body is provided with a slide mechanism.

[0016] The slide mechanism extends in a direction parallel to the first direction, and the slide rail is slidably connected to the slide mechanism. The slide mechanism and the slide rail cooperate to allow the first body and the second body to respectively drive the first side panel and the second side panel to move relative to or away from each other, thereby achieving non-interference between the seat back and the seat.

[0017] In another possible embodiment of the first aspect, at least a portion of the slide mechanism extends obliquely downward along the first direction. In some embodiments, the second accommodating portion is deeper than the first accommodating portion, and the downward tilt of the slide mechanism can smoothly drive the second side panel into the second accommodating portion, further increasing the foldable angle of the seat.

[0018] In another possible embodiment of the first aspect, the slide mechanism includes a first portion and a second portion, the first portion and the second portion being arranged sequentially along a first direction, the first portion extending parallel to the first direction, and the second portion extending obliquely downward along the first direction. In the above embodiment, the first portion corresponds to the first accommodating portion, and the second portion corresponds to the second accommodating portion. Since the second accommodating portion is deeper than the first accommodating portion in some embodiments, tilting the second portion can guide the second side panel into the second accommodating portion.

[0019] In another possible embodiment of the first aspect, the first accommodating portion includes a first side wall and a first bottom wall, and the second side panel includes a first surface and a second surface. When the seat is in the unfolded state, the first surface contacts the first bottom wall, the second surface faces the first side wall, and the second surface and the first side wall are parallel to each other. The first surface and the first bottom wall are in surface contact, so that the second side panel is stably connected to the first side panel, which can prevent the second side panel from shaking, and can increase the structural compactness of the side panel, reduce the volume of the side panel, and reduce the space occupied by the side panel, which is conducive to space saving. The second surface and the first side wall are parallel to each other, so that the gap between the second surface and the first side wall can be very small or even non-existent, further improving the structural compactness of the side panel, reducing the volume, saving space, ensuring the matching degree of the first side panel and the second side panel when the seat is in the unfolded state, and the aesthetics are also good.

[0020] In another possible implementation of the first aspect, when the seat is in the folded state, at least a portion of the side wings of the seat backrest are located within the first accommodating portion, thereby preventing interference between the side panels and the side wings of the seat, which would affect the forward tilting angle of the side wings, and further increasing the foldable angle of the seat.

[0021] In another possible embodiment of the first aspect, the lower side of the side wing of the backrest faces the first side wall of the first accommodating portion, and the lower side of the side wing is parallel to the first side wall. The lower side and the first side wall are parallel to each other, so that the gap between the lower side and the first side wall can be very small or even non-existent, further preventing interference between the side panel and the side wing of the seat, which would affect the angle at which the side wing tilts forward, thereby saving space.

[0022] In another possible embodiment of the first aspect, when the seat is in the folded state, the second surface faces the second side wall of the second accommodating portion, and the second surface and the second side wall are mutually parallel. The second surface and the second side wall are mutually parallel, so that the gap between the second surface and the first side wall can be very small or even non-existent, further improving the structural compactness of the side panel, reducing its volume, saving space, ensuring the matching of the first side panel and the second side panel when the seat is in the folded state, and improving aesthetics. In the folded state, the compact structure of the side panel saves space and can accommodate the backrest, allowing the backrest to fold to a wider angle.

[0023] In another possible implementation of the first aspect, when the seat is in the folded state, the angle between the back surface of the seat backrest and the horizontal plane is within ±20°. In some embodiments, 0° is the angle between the horizontal plane, with the seat backrest's extended direction being considered a positive angle and the seat backrest's folded direction being considered a negative angle. For example, the angle between the back surface of the seat backrest and the horizontal plane is +18°, +15°, +10°, etc.

[0024] It can be seen that the implementation method of the present application can enable the seat backrest to be highly folded, providing more possibilities for users to use the space inside the car and improving the user experience.

[0025] In another possible embodiment of the first aspect, the seat further includes a leg rest connected to a side of the seat cushion away from the backrest; the leg rest includes a supported state and a retracted state; when the leg rest is in the retracted state, the angle between the leg rest and the seat cushion is a first angle; when the leg rest is in the supported state, the angle between the leg rest and the seat cushion is a second angle, the first angle being smaller than the second angle. Because the seat cushion may tilt downwardly along the first direction as the second body moves, the leg rest may also tilt downwardly along the first direction with the seat cushion. As a result, the seat cushion may contact the vehicle floor or ground during movement, preventing the second body from continuing to move or damaging the seat cushion. Setting the leg rest in a supported state and a retracted state can avoid such a situation.

[0026] A second aspect of the present application provides a terminal comprising any of the seats of the first aspect. Optionally, the terminal comprises a vehicle, a transport robot, or a ship, or a transportation vehicle. Alternatively, the terminal comprises a smart device comprising a seat, such as an electric sofa, a 4D cinema cabin, or a massage chair. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In passenger vehicles, the position and posture of seats can be adjusted to enhance the riding experience. Generally speaking, seats in a vehicle can be deployed or folded, with different postures providing different benefits. For example, folding the rear seats provides greater cargo space. In a two-door, four-seat vehicle, folding the front seats provides access to the rear seats.

[0045] However, the folding function of current front seats is not ideal. For details, see Figures 1A and 1B. Figure 1A is a side view of a conventional seat in a folded position, and Figure 1B is a structural diagram of a conventional seat in a folded position. In Figures 1A and 1B, the side panels 11 are integrally structured and arranged on the sides of the seat 10. They primarily shield the seat frame 10 and provide support for switches mounted on the side panels 11, enhancing stability and ensuring passenger comfort and safety. The side panels 11 also secure the position and internal components of the seat 10 and provide support for the passenger's hands and legs. Because the backrest 14 of current automotive seats 10 is designed to provide a sense of envelopment and lumbar support, the backrest 14 of the seat 10 is often designed to be more ergonomically designed. For example, the lumbar support of the backrest 14 is convex forward to support the passenger's lumbar area, and side wings 141 or wing-like protrusions extend from both sides of the backrest 14 to provide a more enveloping feel. When the seat 10 is tilted forward and folded, the above-mentioned design that makes the passengers feel more supported and wrapped when riding seriously interferes with the side panels 11 arranged on both sides of the seat 10, resulting in the side panels 11 hindering the seat back 14 from flipping forward. In this case, the seat 10 cannot be completely laid flat.

[0046] Some vehicles are also equipped with queen seats. Consider a possible scenario. The queen seat is formed by folding the front passenger seat forward and moving the seat forward to provide rear passengers with a larger in-car activity space and a wider field of view. The folded seat can serve as a support for the feet or legs of rear passengers. However, when the front seat back is folded, it still has a large tilt angle, which seriously affects the passengers' riding experience and the breadth of vision.

[0047] In view of this, an embodiment of the present application provides a seat that can prevent the side panels from hindering the seat back from flipping forward, thereby increasing the foldable angle of the seat.

[0048] The following describes a seat provided by an embodiment of the present application using a car seat as an example. It should be noted that, in addition to vehicles, the seat 10 provided by the present application can be applied to other terminals with seats, such as ships, airplanes, or passenger-carrying equipment. The description herein is based solely on a car seat as an example.

[0049] In the following illustrations and descriptions, a solution to the problem of interference between the side wings of the seat back and the side panels when the seat is folded is specifically explained. It can be understood that in addition to the problem of interference between the side wings of the seat back and the side panels, the interference problem between other designs of the seat back and the side panels can also be solved by the following solution.

[0050] Referring to Figures 1C and 1D , Figure 1C is a schematic diagram of a seat provided in an embodiment of the present application in a folded state, and Figure 1D is a schematic diagram of a seat provided in an embodiment of the present application in an unfolded state. As shown in Figures 1C and 1D , seat 10 includes side panels 11 and a backrest 14 , with side wings 141 extending forward and tilted on either side of the backrest 14 .

[0051] The side panel 11 is provided on one side of the seat 10, where the side panel 11 is adjacent to the side where the backrest 14 is located among the four sides of the seat cushion of the seat 10. Optionally, the number of the side panels 11 can be multiple, for example, two side panels 11 are respectively provided on both sides of the four sides of the seat cushion adjacent to the side where the backrest is located.

[0052] In Figures 1C and 1D , the side panel 11 is a split structure, including a first side panel 12 and a second side panel 13. The first side panel 12 matches the second side panel 13. Matching can be understood as the contact portions of the first side panel 12 and the second side panel 13 being aligned or having the same shape. When the seat is unfolded, the first and second side panels can be spliced ​​into a single unit. When the seat is folded, the first and second side panels can be separated into two parts.

[0053] In some embodiments, there is a connection relationship between the first side panel and the second side panel, and the connection relationship between the first side panel and the second side panel includes a detachable connection. The detachable connection includes but is not limited to: the first side panel and the second side panel are connected using fasteners or are slidably connected through a sliding mechanism. Exemplarily, the above-mentioned fastener connection includes a combination of screws, bolts and nuts, and the above-mentioned sliding mechanism includes a combination of slide grooves and slide rails.

[0054] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "matching" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, a conflicting connection, or an integral connection; wherein, "connection" can also be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. For example, in this application, the first side panel 12 and the second side panel 13 are indirectly connected. The indirect connection here can be understood as the first side panel 12 and the second side panel 13 are driven to move by the connection relationship with other components to achieve an indirect connection.

[0055] Optionally, the first side panel 12 and the second side panel 13 are directly connected. For example, the first side panel 12 and the second side panel 13 are slidably connected. The following exemplary sliding connection method is given, where the first side panel 12 and the second side panel 13 are slidably connected via a slide groove mechanism provided on the first side panel 12 and a slide rail provided on the second side panel 13. The specific implementation method of the sliding connection is not limited here.

[0056] In the present application, the first side panel 12 and the second side panel 13 can move closer to or farther from each other along a first direction, which is a direction from the rear side to the front side of the seat 10 .

[0057] It can be understood that when the seat 10 is in the unfolded state, the first side panel 12 and the second side panel 13 are close to each other, and when the seat 10 is in the folded state, the first side panel 12 and the second side panel 13 are away from each other, so as to avoid the side panel 11 hindering the backrest 14 from flipping forward.

[0058] In the present application, the side panels 11 are separately arranged. When the seat 10 is in a folded state, the first side panel 12 and the second side panel 13 in the side panel 11 are away from each other, so that an accommodating space for the side wings 141 of the backrest 14 appears between the first side panel 12 and the second side panel 13. This solves the problem that when the seat 10 is folded, the side wings 141 of the backrest 14 seriously interfere with the side panels 11, and the side panels 11 hinder the backrest 14 from flipping forward.

[0059] In some possible embodiments, the first side panel 12 is provided with a first accommodating portion 121, which is used to accommodate the second side panel 13 or a portion of the second side panel 13. For details, please refer to Figure 2, which is a structural schematic diagram of a first side panel provided in an embodiment of the present application.

[0060] In FIG. 2 , the first receiving portion 121 includes a first side wall 1212 and a first bottom wall 1211 , and the first side wall 1212 and the first bottom wall 1211 together constitute the first receiving portion 121 .

[0061] Optionally, when the seat 10 is in the unfolded state, at least a portion of the second side panel 13 is accommodated in the first accommodating portion 121 to ensure the aesthetics and integrity of the side panel 11 when the seat 10 is in the unfolded state; correspondingly, when the seat 10 is in the folded state, at least a portion of the second side panel 13 is separated from the first accommodating portion 121 to ensure the aesthetics and integrity of the side panel 11 when the seat 10 is in the folded state.

[0062] In the embodiment of the present application, the first accommodating portion 121 is also used to accommodate the side wings 141 of the backrest 14. When the seat 10 is in the folded state, at least a portion of the side wings 141 of the backrest 14 is located within the first accommodating portion 121. For example, in FIG1D , at least a portion of the side wings 141 of the backrest 14 is located within the first accommodating portion 121. It will be understood that when the side wings 141 are stored in the first accommodating portion 121, the horizontal position of the side wings 141 is lowered, and the folding angle of the backrest 14 is larger.

[0063] Furthermore, when the seat 10 is in a folded state, the lower side surface 1411 of the side wing 141 of the backrest 14 faces the first side wall 1212 of the first accommodating portion 121, and the lower side surface 1411 of the side wing 141 and the first side wall 1212 are parallel to each other, thereby avoiding mutual influence between the lower side surface 1411 of the side wing 141 and the first accommodating portion 121 when the seat 10 is folded, thereby improving the accommodating effect.

[0064] Furthermore, the aforementioned queen-size seats that need to fold have requirements for the folding angle. In order to provide support for the passengers' legs and feet, if the seat is not completely folded and the backrest cannot be laid flat, the passenger's riding experience and field of vision will be affected. The present application provides space for the side wings 141 of the backrest 14 or other designs that interfere with the side panels 11 by separately disposing the first side panel 12 and the second side panel 13. This prevents the side panels 11 from interfering with the backrest 14, allowing the backrest 14 of the seat 10 to be laid flat, thereby improving the passenger's riding experience and field of vision. In some queen-size seat designs, the passenger of the queen-size seat sits in the rear seat of the folding seat 10 and can place their feet or legs on the backrest 14 of the folded seat 10.

[0065] Furthermore, since the seat 10 in the queen-size seat needs to be folded, in addition to the folding angle requirements, the seat 10 must be moved forward until a portion of the seat 10 is moved under the armrest box to create more passenger space for the passenger. However, if the backrest 14 or the side wings 141 of the backrest 14 interfere with the side panels 11, resulting in incomplete forward tilting of the backrest 14, the folded portion of the seat 10 may not be able to be moved under the armrest box, resulting in insufficient passenger space. However, the present application, through the above-mentioned design, allows the seat 10 to fold more completely, making it easy to move the folded portion of the seat 10 under the armrest box.

[0066] Optionally, when the seat 10 is in the folded state, the lower side 1411 of the side wing 141 contacts the first side wall 1212 of the first accommodating portion 121, or a portion of the lower side 1411 of the side wing 141 contacts the first side wall 1212 of the first accommodating portion 121. Furthermore, when the seat 10 is in the folded state, the lower side 1411 of the side wing 141 does not completely contact the first side wall 1212 of the first accommodating portion 121, and a small gap exists.

[0067] Optionally, the lower side surface 1411 of the side wing 141 has the same shape as the first side wall 1212 , so that when the seat 10 is folded, the lower side surface 1411 of the side wing 141 and the first side wall 1212 do not interfere with each other.

[0068] In actual application, due to errors in parts processing, the lower side surface 1411 of the side wing 141 is not completely parallel to the first side wall 1212, but the angle formed between the lower side surface 1411 of the side wing 141 and the first side wall 1212 is between ±5°.

[0069] Of course, different seats 10 are provided with side wings 141 of different specifications and models. Accordingly, the positions at which different side wings 141 interfere with the side panels 11 are different. The present application provides corresponding accommodation space for the side wings 141 by separating the first side panel 12 and the second side panel 13 when the seat 10 is in a folded state, which is suitable for the styles of most seats 10 and seat 10 backrest 14 side wings 141 on the market.

[0070] However, due to the differences in length or width of the side wings 141 between different models, some models may have side wings 141 that are shorter and cannot be accommodated in the first accommodating portion 121 when the seat 10 is folded. In this case, when the seat 10 is folded, at least a portion of the side wings 141 is located above the first accommodating portion 121, that is, in the storage space formed after the first side panel 12 and the second side panel 13 move away from each other. Optionally, the storage space can be the portion of the space occupied by the second side panel 13 before the first side panel 12 and the second side panel 13 move away from each other, or the portion of the space occupied by the first side panel 12 before the first side panel 12 and the second side panel 13 move away from each other.

[0071] In some possible embodiments, please refer to FIG3 , which is a schematic diagram of a first side panel and a second side panel approaching each other provided in an embodiment of the present application. In FIG3 , the second side panel 13 includes a first surface 131 and a second surface 132. When the seat 10 is in the unfolded state, the first surface 131 contacts the first bottom wall 1211, and the second surface 132 faces the first side wall 1212. The second surface 132 and the first side wall 1212 are parallel to each other. In FIG3 , the second side panel 13 is a regular rectangular parallelepiped. However, in actual applications, in order to adapt to different first side panels 12 or to achieve higher connection stability with the seat itself, the second side panel 13 can also be an irregular rectangular parallelepiped or other irregular shape. However, it should be noted that in order to ensure the integrity of the side panel 11, the contact surface of the second side panel 13 and the first side panel 12 should be consistent in shape. For example, the contact surface of the second side panel 13 and the first side panel 12 are both smooth planes.

[0072] Optionally, when the seat 10 is in the deployed state, the second surface 132 contacts the first side wall 1212 .

[0073] Optionally, when the seat 10 is in the unfolded state, a portion of the first surface 131 contacts the first bottom wall 1211 .

[0074] In the above embodiment, the first surface and the first bottom wall are in surface contact, allowing the second side panel to be stably connected to the first side panel, preventing the second side panel from shaking. This also increases the structural compactness of the side panel, reduces the volume of the side panel, and reduces the space occupied by the side panel, thereby saving space. The second surface and the first side wall are parallel to each other, so that the gap between the second surface and the first side wall can be very small or even non-existent, further improving the structural compactness of the side panel, reducing the volume, and saving space.

[0075] In some possible embodiments, the first side panel 12 is further provided with a second accommodating portion 122. For details, see Figure 4, which is a schematic diagram of the structure of a first side panel according to an embodiment of the present application. In Figure 4, the first accommodating portion 121 and the second accommodating portion 122 are arranged sequentially along the first direction described above. Along the second direction, the depth of the second accommodating portion 122 is greater than the depth of the first accommodating portion 121. The second direction is from top to bottom of the seat 10. The second accommodating portion 122 includes a second side wall 1221.

[0076] In this embodiment, when the seat 10 is in the folded state, at least a portion of the second side panel 13 is accommodated in the second accommodation portion 122 .

[0077] Optionally, when the seat 10 is in the folded state, the second surface 132 of the second side panel 13 faces the second side wall 1221 of the second accommodating portion 122, and the second surface 132 and the second side wall 1221 are parallel to each other. Optionally, the second surface 132 and the second side wall 1221 are in contact with each other.

[0078] In the above embodiment, the second surface and the second side wall are parallel to each other or in surface contact, so that the gap between the second surface and the first side wall can be very small or even non-existent, further improving the structural compactness of the side panel, reducing the volume, saving space, ensuring the matching degree of the first side panel and the second side panel when the seat is in a folded state, and having better aesthetics. In the folded state, the structure of the side panel is compact and the space saved can accommodate the backrest, allowing the backrest to be folded to a larger angle.

[0079] In some possible embodiments, in order to ensure the stability between the first side panel 12 and the seat 10, the first side panel 12 also includes a third side wall 1231. The third side wall 1231 can be a side wall that contacts the first side panel 12 and the seat 10. Optionally, the third side wall 1231 is a side wall with thickness. Please refer to Figure 5 for details. Figure 5 is a structural schematic diagram of another first side panel provided in an embodiment of the present application.

[0080] In Figure 5 , the third side wall 1231 extends along the first direction and is provided with a third receiving portion 123 at the front end of the seat 10. The third receiving portion 123 is used to accommodate at least a portion of the second side panel 13 when the seat 10 is folded. The front end of the first side panel 12 allows for the second side panel 13 to be accommodated. Therefore, a notch is provided at the front end of the first side panel 12 in the Y direction (generally, the left-right direction of the seat 10). This notch accommodates and matches the movable second side panel 13, forming a single unit and ensuring the seat 10 has a good appearance. It will be appreciated that the third receiving portion 123 is designed at the front end of the third side wall 1231 to match the structure of the second side panel 13 when the seat is folded. In this case, the second side panel 13 has an irregular shape. The third receiving portion 123 shown in Figure 5 is illustrative. In actual applications, the third receiving portion 123 may be located at any one or more locations on the third side wall 1231 to better match the shapes of the first and second side panels 12 and 13.

[0081] In some possible implementations, please refer to FIG6 , which is a schematic diagram of the structure of a seat body provided in an embodiment of the present application. In FIG6 , the seat body 15 includes a first body 151 and a second body 152, the first body 151 and the second body 152 being slidably connected. Along a first direction, the first body 151 and the second body 152 can approach or move away from each other. The first body 151 is fixedly connected to the first side panel 12, and the second body 152 is fixedly connected to the second side panel 13. Therefore, the movement state of the seat body 15 in different postures of the seat 10 is similar to the first side panel 12 and the second side panel 13 in the side panel 11. When the seat 10 is in the unfolded state, the first body 151 and the second body 152 are close to each other, and when the seat 10 is in the folded state, the first body 151 and the second body 152 are away from each other.

[0082] Optionally, the above-mentioned side panel 11 is arranged on one side of the seat body 15. Exemplarily, the side panel 11 includes two side panels respectively arranged on both sides of the seat body 15, or the side panel 11 is an integrally formed structural part, which is arranged on the periphery of the seat body 15 to wrap part of the seat body 15.

[0083] In the embodiment of the present application, when the second body 152 moves away from the first body 151 , it drives the structural parts fixedly connected thereto to move together, such as the second side panel 13 , the seat cushion or the seat leg support.

[0084] In an embodiment of the present application, when the seat 10 is in a folded state, the second body 152 and the second side panel 13 move along the first direction compared to the first body 151 and the first side panel 12. In this case, the first body 151 and the first side panel 12 are in a fixed state compared to the seat 10, and the second body 152 and the second side panel 13 move along the first direction to leave corresponding placement space for the backrest 14, thereby avoiding the situation where the side panel 11 hinders the backrest 14 from tilting forward.

[0085] Optionally, when the seat 10 is in the folded state, the second body 152 and the second side panel 13 move along the first direction, and the first body 151 and the first side panel 12 move along the opposite direction of the first direction.

[0086] Optionally, when the seat 10 is in the folded state, the second body 152 and the second side panel 13 are fixed relative to the seat 10 , and the first body 151 and the first side panel 12 move in a direction opposite to the first direction.

[0087] In some possible embodiments, the first body 151 is provided with a slide mechanism 153, which is specifically a groove recessed in the upper surface of the first body 151, and the second body 152 is provided with a slide rail, which can be a long strip-shaped structure protruding from the surface of the second body 152. Alternatively, the first body 151 is provided with a slide rail, and the second body 152 is provided with a slide mechanism 153. The slide mechanism 153 extends in a direction parallel to the first direction, and the slide rail and the slide mechanism 153 are slidably connected. In the embodiment of the present application, the second body 152 can move in the first direction via the slide mechanism 153 or the slide rail, thereby driving the second side panel 13 fixedly connected to the second body 152 to move together. Of course, the motion mechanism provided in the seat body 15 can be other mechanisms besides the slide mechanism 153 and the slide rail, such as a transmission shaft, a conveyor belt, a telescopic bearing, etc., which can support the movement of the first body 151 and the second body 152 in the seat body 15. Please refer to Figures 7 and 8. Figure 7 is a side view of a slide mechanism within a seat provided in an embodiment of the present application, and Figure 8 is a side view of another slide mechanism within a seat provided in an embodiment of the present application. The seat 10 in Figure 7 is in an unfolded state, while the seat 10 in Figure 8 is in a folded state. The slide mechanism 153 in Figures 7 and 8 is fixedly connected to the first body.

[0088] In some other possible embodiments, at least a portion of the slide slot mechanism 153 extends obliquely downward along the first direction. It is understandable that at least a portion of the slide rail matching the slide slot mechanism 153 also extends obliquely downward along the first direction.

[0089] In some other possible embodiments, the slide mechanism 153 includes a first part 1531 and a second part 1532, and the first part 1531 and the second part 1532 are arranged in sequence along the first direction, and the extension direction of the first part 1531 is parallel to the first direction; the second part 1532 extends obliquely downward along the first direction. Please refer to Figure 9 for details. Figure 9 is a schematic diagram of a slide mechanism provided in an embodiment of the present application.

[0090] In this embodiment, when the slide rail on the second body 152 moves to the second portion 1532 of the slide slot mechanism 153, the second side plate 13 fixedly connected to the second body 152 moves to the second receiving portion 122. Alternatively, when the slide rail on the second body 152 moves to the second portion 1532 of the slide slot mechanism 153, the second side plate 13 fixedly connected to the second body 152 moves to the second receiving portion 122 and the third receiving portion.

[0091] In the above embodiment, the first side panel 12 and the second side panel 13 are moved closer to or further away from each other by means of a motion mechanism (a slide mechanism 153 and a slide rail) provided in the seat body 15. In other embodiments, the first side panel 12 and the second side panel 13 can also be moved closer to or further away from each other by means of other motion mechanisms. For example, the slide mechanism 153 is provided on the side of the seat body 15 facing the side panel 11, and slide rails matching the slide mechanism 153 are provided on the first side panel 12 and the second side panel 13, respectively. In this case, the movement of the first side panel 12 and the second side panel 13 can be achieved by means of the cooperation between the slide mechanism 153 and the slide rails; or a drive assembly is provided below the side panel 11, and the drive assembly is used to drive the first side panel 12 and / or the second side panel 13 to move, etc.

[0092] The key to the embodiment of the present application is to provide placement space for the side wings 141 of the backrest 14 when the seat 10 is folded by separating the first side panel 12 and the second side panel 13. Therefore, the slide mechanism 153 and the slide rail provided in the present application are only for illustrative purposes, and the specific implementation method of separating the first side panel 12 and the second side panel 13 is not limited here.

[0093] In some other possible embodiments, the seat 10 also includes a seat cushion 16. Relatively speaking, the seat cushion 16 is in the front, and the backrest 14 is located behind the seat cushion 16. Since the adjuster / rotating shaft for adjusting the tilt angle of the backrest 14 is generally set at the bottom of the backrest 14, and the bottom of the backrest 14 is in contact with the rear end of the seat cushion 16, when the front seat 10 is folded forward, the backrest 14 interferes seriously with the seat cushion 16 and the side panel 11, making it impossible to fold it flat, resulting in a large tilt angle after the seat 10 is folded, affecting the comfort of the passengers in the queen seat 10.

[0094] Therefore, in this embodiment, the backrest 14 is rotatably connected to the first body 151, and the seat cushion 16 is fixedly connected to the second body 152. When the first body 151 and the second body 152 approach each other or move away from each other, the seat cushion 16 and the second body 152 move together. It can be understood that when the seat 10 is in a folded state, the seat cushion 16 and the second body 152 move together, away from the first body 151, to avoid the seat cushion 16 interfering with the backrest 14 and affecting the foldable angle of the seat 10.

[0095] In order to ensure that when the seat 10 is folded, the backrest 14 tilts forward and is about to contact the seat cushion 16, the backrest 14 body will not be interfered with by the seat cushion 16, and the side wings 141 of the backrest 14 will not be interfered with by the side panels 11, in some other possible embodiments, the backrest 14 moves synchronously with the second body 152, that is, when the backrest 14 starts to tilt forward, the second body 152 starts to move forward along the first direction, and before the backrest 14 completes the tilting action, the second body 152 reaches the expected target position, leaving space for the backrest 14 and / or the side wings 141 of the backrest 14. The above-mentioned change in movement state is exemplary. In addition to the above-mentioned method of synchronous movement of the backrest 14 and the second body 152, the second body 152 can also move to the expected target position in advance before the backrest 14 starts to tilt forward.

[0096] In some possible embodiments, when the seat 10 is in the folded state, the angle between the back of the backrest 14 of the seat 10 and the horizontal plane is between ±20°. Alternatively, in an embodiment of the present application, the foldable angle of the seat 10 is 79°. If the angle between the back of the backrest 14 and the horizontal plane is 97° when the seat 10 is in the unfolded state, then when the seat 10 is in the folded state, the angle between the back of the backrest 14 and the horizontal plane is +18°. In some embodiments, 0° is the angle of the horizontal plane, with the unfolded direction of the backrest 14 being a positive angle and the folded direction of the backrest 14 being a negative angle. For example, the angle between the back of the backrest 14 of the seat 10 and the horizontal plane is +18°, +15°, +10°, etc. It can be seen that the embodiments of the present application enable the backrest 14 of the seat 10 to be folded to a high degree, providing passengers with more possibilities for using the vehicle interior space and improving the user experience.

[0097] The current car seat 10 is provided with a leg rest 17, which is generally connected to the side of the seat cushion 16 of the seat 10 away from the backrest 14, perpendicular to the horizontal plane, to support the legs of the passenger in the seat 10 and improve the passenger's riding comfort. In some possible embodiments of the present application, the seat cushion 16 will move downwardly along the first direction with the second body 152, causing the leg rest 17 to move downwardly along the first direction with the seat cushion 16. As a result, the seat cushion 16 may press against the vehicle floor or the ground during movement, causing the second body 152 to be unable to continue moving or the seat cushion 16 to be damaged.

[0098] Therefore, in some possible embodiments, the seat 10 also includes a leg rest 17, which is connected to the side of the seat cushion 16 away from the backrest 14; the leg rest 17 includes a supporting state and a retracted state; when the leg rest 17 is in the retracted state, the angle between the leg rest 17 and the seat cushion 16 is a first angle 171, and when the leg rest 17 is in the supporting state, the angle between the leg rest 17 and the seat cushion 16 is a second angle 172. Please refer to Figures 10A, 10B, 11A and 11B for details. Figure 10A is a side view of another seat in the unfolded state provided in an embodiment of the present application, Figure 10B is a schematic diagram of a first angle provided in an embodiment of the present application, Figure 11A is a side view of another seat in the folded state provided in an embodiment of the present application, and Figure 11B is a schematic diagram of a second angle provided in an embodiment of the present application.

[0099] In the embodiment of the present application, the first angle 171 is smaller than the second angle 172 .

[0100] It can be understood that when the seat 10 is in the unfolded state, the leg rest 17 is in the retracted state, retracted at the seat body 15 , and when the seat 10 is in the folded state, the leg rest 17 is in the supporting state.

[0101] In some possible embodiments, a recliner 18 is provided at the top of the first side panel 12. The recliner 18 is a mechanism for adjusting the inclination angle of the backrest 14. For example, the recliner 18 can be provided on the inner side or outer side of the first side panel 12, the inner side being the side facing the seat body 15, and the outer side being the side facing outside the seat 10. The recliner 18 can also be provided inside the first side panel 12. Accordingly, a groove or through hole matching the recliner 18 is provided in the first side panel 12.

[0102] In some possible embodiments, a button may be provided on the second side panel 13. As shown in FIG10A and FIG10B , an adjustment button 19 is provided on one side of the second side panel 13. The adjustment button 19 is used to adjust the position of the seat 10 or the inclination angle of the backrest 14 or the leg rest 17. Of course, the adjustment button 19 may also be provided on the first side panel 12.

[0103] The present application also provides a terminal comprising the seat 10 described in the aforementioned embodiment. Optionally, the terminal comprises an intelligent terminal or vehicle, such as a vehicle, robot, drone, or ship. The vehicle is defined broadly as a commercial vehicle, passenger car, motorcycle, flying car, train, or specialized vehicle. Alternatively, the terminal comprises an intelligent device comprising a seat, such as an electric sofa, a 4D cinema cabin, or a massage chair.
