Description

Technical Field

[0001] This application relates to the field of vehicle seat technology, and in particular to a seat folding system, a body system, and a vehicle. Background Technology

[0002] In the field of automotive design, to meet users' needs for flexible vehicle storage space, the folding and flipping function of rear seats has become one of the key technologies for improving luggage compartment expansion capabilities. Currently, there are two main technical approaches in the industry for expanding luggage compartment space through seat folding and flipping, but both have significant technical shortcomings.

[0003] One solution involves flipping the seat cushion and backrest 180° to lay them flat onto the luggage compartment and seat floor. This solution unfolds the seat components to cover part of the luggage area by flipping them over. However, since the seat cushion and backrest themselves have a certain thickness, after being flipped and laid flat, their thickness will occupy the effective space in the height direction of the luggage compartment, resulting in the actual usable space of the luggage compartment not being maximized and the space utilization rate being significantly insufficient.

[0004] Another approach involves folding the backrest and seat cushion and then flipping them down into the luggage compartment. To achieve a flat luggage floor after folding, this approach often requires reducing the thickness of the seat cushion and backrest. By sacrificing the thickness of the seat padding to achieve flatness, the seat's comfort is significantly reduced, making it difficult to meet the user's basic needs for seat comfort.

[0005] In practical applications, the overall vehicle height is limited by multiple constraints such as vehicle styling design and overall configuration layout, leaving very limited space for seat installation. Under these circumstances, even with a thin seat structure, it is still difficult to ensure the flatness of the trunk floor after the seat is folded down, resulting in an irreconcilable contradiction between seat thickness and trunk floor flatness.

[0006] In existing technologies, when the seat back and cushion are folded and flipped into the luggage compartment, there is always a technical challenge in how to ensure the thickness of the seat to maintain comfort while achieving a flat luggage compartment floor. Utility Model Content

[0007] In view of the deficiencies in the prior art, this application provides a seat folding system, a body system, and a vehicle to solve the problem of difficulty in coordinating the utilization rate and flatness of the seat after folding in the prior art.

[0008] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0009] A seat folding system, the seat folding system comprising:

[0010] The seat module can be fixedly mounted on the vehicle frame or can be rotated into an accommodating space on the vehicle frame. The seat module includes a seat cushion and a backrest that can be folded onto the seat cushion.

[0011] The linkage has a first rotating part and a second rotating part that are correspondingly hinged to the seat cushion and the frame. The seat module can rotate and can pull the linkage to flip so that the linkage can be horizontally positioned between the seat cushion and the frame.

[0012] In an optional embodiment, the first rotating part is arranged on one side edge of the linkage.

[0013] In an optional embodiment, the first rotating part is connected to the bottom surface of the cushion.

[0014] In an optional embodiment, the first rotating part is connected to the middle of the bottom surface of the seat cushion, and when the seat module rotates into the accommodating space on the frame, the linkage has an overlapping area with the bottom surface of the seat cushion.

[0015] In an optional embodiment, the second rotating part is arranged in the middle of the linkage, and when the seat module rotates into the accommodating space on the frame, the linkage and the frame have an overlapping area.

[0016] In an optional embodiment, the first rotating part adopts a rotating shaft mechanism.

[0017] In an optional embodiment, the second rotating part employs a roller mechanism.

[0018] In an optional embodiment, the linkage component is an alloy baffle.

[0019] Based on the same inventive concept, this application also provides a vehicle body system, which includes the seat folding system as described above.

[0020] Based on the same inventive concept, this application also provides a vehicle that includes the body system described above.

[0021] Compared with the prior art, the advantages of this application are:

[0022] The seat folding system of this application includes a seat module and a linkage. The seat module can be fixedly mounted on the vehicle frame or rotated into an accommodating space on the vehicle frame. The seat module includes a seat cushion and a backrest that can be folded onto the seat cushion. The linkage has a first rotating part and a second rotating part that are correspondingly hinged to the seat cushion and the vehicle frame. The seat module can rotate and can pull the linkage to flip so that the linkage can be horizontally positioned between the seat cushion and the vehicle frame.

[0023] This seat folding system includes a seat module that can be fixed to the frame or rotated into the frame's storage space, and a linkage with a first and second rotating part corresponding to the hinged seat cushion and the frame. The backrest of the seat module can be folded onto the seat cushion. When the seat module needs to be folded into the luggage compartment, the rotation of the seat module pulls the linkage to rotate synchronously, allowing the linkage to be horizontally positioned between the seat cushion and the frame. This firstly solves the problem of traditional 180° folding and flattening technology occupying height space: the seat module can rotate into the frame's storage space, avoiding its own thickness encroaching on the luggage compartment space in the height direction, while the horizontal positioning of the linkage provides stable support, ensuring that after the seat module is folded into place, the luggage compartment area can form a flat usable area, maximizing space utilization. At the same time, this seat folding system does not require reducing the thickness of the seat cushion and backrest to achieve flatness, because the supporting effect of the linkage allows the seat module to sink into the storage space through a reasonable rotation trajectory while maintaining sufficient thickness for comfort, effectively balancing seat comfort and luggage compartment flatness.

[0024] Furthermore, addressing the issue of insufficient seat installation space due to the limited overall vehicle height, the design of the coordinated flipping of the seat module and its linkage optimizes the space occupation trajectory of the seat during folding. Even within a limited installation space, the seat module can be smoothly flipped and installed, ultimately achieving the technical effect of improving the flexibility of the trunk space while ensuring passenger comfort and a flat trunk floor. This significantly improves the overall performance of the vehicle and effectively solves the problems of low space utilization, poor comfort, and insufficient flatness of the trunk floor in existing technologies.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0030] like Figure 1 , Figure 2 As shown, Figure 1 This is a structural diagram of the seat folding system provided in the embodiment of this application in the first state, in which the seat cushion 101 and backrest 102 in the seat module 100 are in the open state. Figure 2 This is a structural diagram of the second state of the seat folding system provided in the embodiment of this application. In this second state, the seat cushion 101 and backrest 102 in the seat module 100 are folded onto the frame 300.

[0031] like Figure 1 , Figure 2 As shown, a seat folding system includes a seat module 100 and a linkage 200, wherein:

[0032] The seat module 100 can be fixedly mounted on the frame 300 or can be rotated into the accommodating space on the frame 300. The seat module 100 includes a seat cushion 101 and a backrest 102 that can be folded onto the seat cushion 101.

[0033] As the core functional carrier of the seat folding system, the seat module 100 can not only be stably installed on the frame 300 through a fixed structure to meet daily riding needs, but also can be precisely rotated into the appropriate storage space on the frame 300 through a preset rotation trajectory to expand the luggage compartment space. The backrest 102 and the seat cushion 101 of the seat module 100 adopt a foldable connection structure, such as a hinge or a flexible pivot, so that the backrest 102 can be flipped and folded around the connecting axis towards the seat cushion 101. During the folding process, the fit between the backrest 102 and the seat cushion 101 can be adjusted by the limiting component to ensure the compactness of the overall structure after folding.

[0034] The linkage 200 has a first rotating part 201 and a second rotating part 202 that are correspondingly hinged to the seat cushion 101 and the frame 300. The seat module 100 can rotate and can pull the linkage 200 to flip so that the linkage 200 can be horizontally positioned between the seat cushion 101 and the frame 300.

[0035] The linkage 200 is hinged to the seat cushion 101 and the frame 300 at both ends via a first rotating part 201 and a second rotating part 202, respectively. Bearing structures or wear-resistant bushings can be used at the hinge points to reduce frictional resistance during rotation. When the seat module 100 rotates from a fixed state into the accommodating space, the seat cushion 101 applies traction to the linkage 200 via the first rotating part 201, causing the linkage 200 to rotate synchronously around the second rotating part 202. The rotation angle of the linkage 200 is in a preset linkage relationship with the rotation angle of the seat module 100, which can be set through a lever ratio or gear transmission structure. When the seat module 100 is fully rotated into the accommodating space, the linkage 200 rotates to a horizontal position, forming a stable support structure, ensuring that the upper surface of the folded seat cushion 101 remains continuous and flush with the floor around the luggage compartment.

[0036] To further optimize system performance, a buffer device, such as a hydraulic damper or a spring buffer structure, can be installed on the flipping trajectory of the linkage 200 to reduce the impact at the end of the flipping. A guide groove and a positioning buckle can be installed in the accommodating space. When the seat module 100 is rotated in, it slides along the guide groove and automatically locks itself in place by the buckle, improving the convenience of operation and the stability of the structure. Alternatively, an angle locking mechanism can be installed at the folding point of the backrest 102 and the seat cushion 101, which can fix the backrest 102 at different folding angles as needed, taking into account the diverse needs of temporary storage and space expansion.

[0037] While ensuring that the seat has sufficient thickness to maintain riding comfort, it avoids the occupation of the luggage compartment height space by the traditional flat flip-up design, and solves the contradiction between thickness and flatness in the folding sink-in technology, effectively achieving efficient coordination between seat function and luggage space.

[0038] like Figure 1 , Figure 2 As shown, in an optional embodiment, the seat folding system of this application includes a seat module 100 and a linkage 200. The seat module 100 can be fixedly mounted on the frame 300 or rotatably mounted in the accommodating space on the frame 300. The seat module 100 includes a seat cushion 101 and a backrest 102 foldable onto the seat cushion 101. The linkage 200 has a first rotating part 201 and a second rotating part 202 that are correspondingly hinged to the seat cushion 101 and the frame 300. The seat module 100 can rotate and pull the linkage 200 to flip, so that the linkage 200 can be horizontally positioned between the seat cushion 101 and the frame 300.

[0039] The seat folding system includes a seat module 100 that can be fixed to or rotated into the accommodating space of the frame 300, and a linkage 200 having a first rotating part 201 and a second rotating part 202 corresponding to the hinged seat cushion 101 and the frame 300. The backrest 102 of the seat module 100 can be folded onto the seat cushion 101. When the seat module 100 needs to be folded into the trunk space, the rotation of the seat module 100 will pull the linkage 200 to fold synchronously, so that the linkage 200 can be horizontally positioned between the seat cushion 101 and the frame 300. This firstly solves the problem of traditional 180° folding and flat-laying technology occupying height space: the seat module 100 can be rotated into the accommodating space of the frame 300, avoiding its own thickness from encroaching on the trunk space in the height direction, while the horizontal positioning of the linkage 200 provides stable support, ensuring that after the seat module 100 is folded into place, the trunk area can form a flat usable area, maximizing space utilization. Meanwhile, the seat folding system does not require reducing the thickness of the seat cushion 101 and backrest 102 in pursuit of flatness, because the supporting effect of the linkage 200 allows the seat module 100 to sink into the storage space through a reasonable rotation trajectory while ensuring sufficient thickness to maintain comfort, effectively balancing seat comfort and luggage flatness.

[0040] Furthermore, to address the issue of insufficient seat installation space due to the limited overall vehicle height, the seat module 100 and the linkage component 200 are linked and flipped together, optimizing the space occupation trajectory of the seat during the folding process. Even within a limited installation space, the seat module 100 can be smoothly flipped and installed, ultimately achieving the technical effect of improving the flexibility of the trunk space while ensuring passenger comfort and a flat trunk floor. This significantly improves the overall performance of the vehicle and effectively solves the problems of low space utilization, poor comfort, and insufficient flatness of the trunk floor in existing technologies.

[0041] like Figure 1 , Figure 2 As shown, in an optional embodiment, the first rotating part 201 is arranged on one side edge of the linkage 200. Arranging the first rotating part 201 on one side edge of the linkage 200 optimizes the force balance of the linkage 200. When the seat module 100 rotates and pulls the linkage 200 to flip, the hinge point on the side edge allows the linkage 200 to flip with a more reasonable torque, reducing jamming during the flipping process, and preventing interference between the linkage 200 and other components of the seat module 100 or the frame 300, ensuring the smoothness of the flipping action.

[0042] like Figure 1 , Figure 2As shown, in an optional embodiment, the first rotating part 201 is connected to the bottom surface of the seat cushion 101. The first rotating part 201, connected to the bottom surface of the seat cushion 101, allows the linkage 200 to be closer to the movement trajectory of the seat cushion 101. When the seat cushion 101 rotates with the seat module 100, the first rotating part 201 located on the bottom surface can directly transmit the traction force of the seat cushion 101, making the rotation of the linkage 200 and the rotation of the seat cushion 101 more precisely coordinated, reducing transmission losses between the two, and improving the overall system response speed.

[0043] like Figure 1 , Figure 2 As shown, in an optional embodiment, the first rotating part 201 is connected to the middle of the bottom surface of the seat cushion 101. When the seat module 100 rotates into the accommodating space on the frame 300, the linkage 200 has an overlapping area with the bottom surface of the seat cushion 101.

[0044] The first rotating part 201 is connected to the center of the bottom surface of the seat cushion 101. When the seat module 100 rotates into the accommodating space on the frame 300, the linkage 200 and the bottom surface of the seat cushion 101 have an overlapping area. The first rotating part 201 connected in the middle enables the linkage 200 to provide more even support to the seat cushion 101, avoiding excessive local stress that could cause deformation of the seat cushion 101. The existence of the overlapping area further enhances the connection stability and reliability of the two. When the seat module 100 is in the accommodating space, this overlapping structure can distribute the load-bearing pressure and improve the overall rigidity of the linkage 200 in this state.

[0045] like Figure 1 , Figure 2 As shown, in an optional embodiment, the second rotating part 202 is arranged in the middle of the linkage 200, and when the seat module 100 rotates into the accommodating space on the frame 300, the linkage 200 and the frame 300 have an overlapping area.

[0046] The second rotating part 202 is located in the middle of the linkage 200. When the seat module 100 rotates into the accommodating space on the frame 300, the linkage 200 and the frame 300 have an overlapping area. The second rotating part 202 in the middle makes the connection between the linkage 200 and the frame 300 more stable. When the linkage 200 is horizontally positioned, the support point in the middle can make the force on the linkage 200 more balanced, reducing deformation caused by uneven force at both ends. At the same time, the overlapping area between the linkage 200 and the frame 300 can increase the contact area between the two, improve the reliability of the support, and ensure the stability and load-bearing capacity of the trunk floor in a flat state.

[0047] like Figure 1 , Figure 2As shown, in an optional embodiment, the first rotating part 201 adopts a pivot mechanism. The pivot mechanism has the characteristics of simple structure and smooth rotation. It can provide a stable relative rotational relationship between the linkage 200 and the seat cushion 101, ensuring that the rotational accuracy of both is not affected during long-term use. Moreover, the pivot mechanism is relatively convenient to install and maintain, which can reduce the manufacturing cost of the system and the difficulty of later maintenance.

[0048] like Figure 1 , Figure 2 As shown, in an optional embodiment, the second rotating part 202 employs a roller mechanism. The roller mechanism has the advantage of low rolling friction during rotation. Simultaneously, the roller mechanism also allows for a certain degree of adaptive relative displacement between the linkage 200 and the frame 300, thereby improving reliability. When the linkage 200 rotates around the second rotating part 202, the rolling motion of the rollers significantly reduces the frictional resistance between the linkage 200 and the frame 300, making the rotation action less strenuous, reducing wear on components, and extending the service life of the connection between the linkage 200 and the frame 300.

[0049] In an optional embodiment, the linkage 200 employs an alloy baffle. The alloy material possesses high strength and good toughness. When used as a baffle, it provides reliable support, bearing the weight of the seat module 100 and any items that may be placed on it, while maintaining structural stability during long-term flipping and support, preventing bending or breakage. Furthermore, the lightweight nature of the alloy material does not add extra weight to the system, avoiding adverse effects on the vehicle's energy consumption. Simultaneously, its surface can be treated with anti-corrosion measures, improving the weather resistance of the linkage 200 and adapting it to the complex operating environment of the vehicle.

[0050] like Figure 1 , Figure 2 As shown, based on the same inventive concept, this application also provides a vehicle body system, which includes the seat folding system as described above. Specifically, in this vehicle body system, except for the seat folding system and related components which adopt the technical solutions in the above embodiments, the structure, connection relationship, installation position, etc. of other devices can refer to the relevant disclosures of the prior art, and will not be elaborated here.

[0051] The integration of this seat folding system into the body system significantly optimizes spatial layout and functional coordination. As the mounting platform for various vehicle components, the utilization rate of the body system's internal space directly impacts the vehicle's practicality. By integrating the aforementioned seat folding system, the body system can maintain the original passenger space while, through the flexible rotation of the seat module 100 and the precise support of the linkage 200, creating a flat and continuous storage surface in the extended state of the luggage compartment. This aligns well with the overall design of the vehicle floor, avoiding the spatial fragmentation issues caused by traditional seat folding methods. Simultaneously, the structural design of the body system can be deeply matched with the accommodating space and rotation trajectory of the seat folding system. For example, a pre-set accommodating groove matching the dimensions of the seat module 100 is incorporated into the frame 300, and sufficient movement clearance is reserved along the flipping path of the linkage 200, ensuring no interference between the seat folding action and the body structure, thus enhancing the functionality and coordination of the body system's internal space. It also reduces redundant structures within the vehicle, reducing weight to some extent and contributing to optimized vehicle energy efficiency.

[0052] Based on the same inventive concept, this application also provides a vehicle, which includes the body system as described above. Specifically, in this vehicle, except that the body system and related components adopt the technical solutions in the above embodiments, the structure, connection relationship, installation position, etc. of other devices can refer to the relevant disclosures of the prior art, and will not be elaborated here.

[0053] Thanks to the aforementioned body system, the vehicle achieves a comprehensive improvement in overall performance and user experience. As a final-use product, a vehicle needs to balance passenger comfort, storage convenience, and overall practicality. With this body system, the rear seats not only provide passengers with a sufficiently thick and comfortable seating experience, but also allow for a simple 100-degree fold-down of the seat modules, quickly transforming the rear space into a flat cargo area. This meets the diverse storage needs of users in various scenarios, including daily commutes, short trips, and long journeys. Furthermore, the vehicle's styling and overall layout do not need to compromise to accommodate the seat folding function. Because the seat folding system operates smoothly within the limited vehicle height and space constraints, the vehicle can maintain an aesthetically pleasing design and rich features while possessing flexible space expansion capabilities. This design enhances the vehicle's market competitiveness and provides users with a convenient, comfortable, and efficient driving experience, fully demonstrating the extension and application value of the same invention concept at different product levels.
