Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a rear seat structure that can be combined and extended, and an automobile. Background Technology

[0002] With the development of automotive technology, the functionality of car seats has also improved. In terms of adjustment methods, car seats mainly include manual and electric options. In addition to the standard fore-and-aft position and backrest angle, the height of the front and rear areas of the seat cushion can also be adjusted separately. Car seats are developing towards diversification and versatility, offering more comprehensive functions and becoming an important feature that people cannot ignore when choosing a car.

[0003] Currently, most car seats on the market use the common fore-and-aft position and backrest angle adjustment methods. As the largest segment of sales is family cars, the seats lack more diverse and varied adjustment options. When temporarily needing to accommodate large or numerous items or for overnight stays in the vehicle, folding down the rear seatbacks provides limited interior space while maintaining the existing vehicle space. Furthermore, the distance between the folded rear seatbacks and the roof is small, resulting in limited height. Lifting the rear seat cushions or removing the seats can temporarily alleviate the space constraints. However, lifting the cushions doesn't significantly change the space; while removing the seats creates more space, the process of removal and reinstallation is cumbersome and laborious, and easily damages the seat surface and the clips at the bottom of the cushion. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rear seat structure and automobile that can be combined and extended, enabling the rear seats of the automobile to have the functions of combining and extending. During daily use, the rear seats can be kept in a normal state. When temporarily accommodating more items or camping in the vehicle, the usable space inside the vehicle can be increased by combining the rear seats. The rear seats can be quickly combined and extended with the help of sliding rails, and the operation is simple.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] Firstly, a rear seat structure that can be combined and extended includes:

[0007] The seat frame is composed of horizontal, longitudinal, and vertical frames connected together. Each seat has a cross-connection of adjacent horizontal frames with support rods. Both the support rods and the horizontal frames are telescopic rod structures. The seat cushion and backrest assembly can be detachably installed on the outside of the seat frame.

[0008] The transverse sliding rail is laid on the rear floor and is used to cooperate with the corresponding transverse frame to push the seat frame, so that the support rod and transverse frame can extend and retract, realizing the merging and extension of the rear seats.

[0009] As a further implementation, the sides of both ends of the transverse frame are provided with fixing points, and the two ends of the support rod are hinged to the fixing points.

[0010] As a further implementation, the support rod between two adjacent transverse frames includes a first support rod and a second support rod, which are arranged in an X-shape.

[0011] As a further implementation, the horizontal frame, the vertical frame, and the vertical frame are fixedly connected perpendicularly to each other.

[0012] As a further implementation, the transverse frames between adjacent rear seats are connected in sequence to allow the seats to be merged into one side of the vehicle body.

[0013] As a further implementation, the seat frame of each rear seat is set independently to allow the seats to be combined to one or both sides of the vehicle body.

[0014] As a further implementation, the transverse slide rail has a groove-like structure, with a bottom transverse skeleton fitted inside the groove. The ends of the bottom transverse skeleton and the corresponding positions of the groove after the bottom transverse skeleton is extended are provided with through holes for use with the locking component to achieve locking.

[0015] As a further implementation, the locking assembly includes a fixing plate at the end of the transverse slide rail, a limiting plate on the side of the fixing plate near the transverse slide rail, a locking shaft connected to the limiting plate via a spring at the through hole facing the transverse slide rail, and a lever at the end of the locking shaft. By pushing the lever backward, the locking shaft can be disengaged from the through hole on the bottom transverse frame and the slide rail.

[0016] As a further implementation, the seat cushion and backrest assembly includes several cylindrical foam components connected by textile fabric. The textile fabric can be clamped between the cylindrical foam components after shrinking with the seat frame.

[0017] Secondly, an automobile having rear seats, wherein the rear seats employ a collapsible and extendable rear seat structure as described above.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. This invention features a transverse sliding rail and a retractable seat frame inside the vehicle. The bottom of the seat frame engages with the transverse sliding rail, allowing the three rear seats to be combined and retracted when the rear space of the vehicle needs to be expanded. When extended, the retracted seats are restored to the initial state of three seats. The operation is simple and convenient. The combined space can meet various needs such as temporary accommodation and camping, and the space is spacious.

[0020] 2. The transverse frame and support rod of the present invention are both support rod structures. When the rear seats are combined, they can be retracted simultaneously to ensure that the overall height of the seats remains unchanged, only the width is reduced.

[0021] 3. The present invention provides a locking component at the transverse slide rail. The rear seats can be folded together by unlocking the locking component, which can ensure installation. Locking components can also be added to the transverse slide rail as needed to lock the rear seats after they are folded together.

[0022] 4. The seat cushion and backrest assembly of the present invention are detachably connected to the seat frame. When merging the rear seats, the seat cushion and backrest assembly can be removed or merged directly. After the seat is folded down, the cylindrical foam material shrinks together, and the connecting fabric is sandwiched between the foam materials, which is not affected by space.

Detailed Implementation

[0036] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0037] Example 1

[0038] In a typical embodiment of the present invention, reference is made to Figures 1-10 As shown, a rear seat structure that can be combined and extended includes a transverse slide rail 1, a seat frame 2, and a seat cushion and backrest assembly 3. The seat cushion and backrest assembly 3 is detachably installed on the outside of the seat frame 2, and the bottom of the seat frame 2 slides in conjunction with the transverse slide rail 1.

[0039] In this embodiment, the seat frame is formed by the horizontal frame 21, the longitudinal frame, and the vertical frame 22 being fixedly connected perpendicularly to each other. Figure 3 As shown, the transverse frame 21 is in the same direction as the vehicle width, and the longitudinal frame is in the same direction as the vehicle length.

[0040] The seat frame 2 is distributed on three surfaces: the backrest, the seat cushion, the front side, and the rear side, from top to bottom. The backrest and the rear side are on the same plane. The bottom of the front side is used to mate with the transverse slide rail 1.

[0041] like Figure 3 As shown, the front side of each seat is connected by a horizontal frame 21 and a vertical frame 22 to form a rectangular structure. There are two horizontal slide rails 1, located on the rear floor body at the bottom position of the front and rear sides, which slide in cooperation with the bottom horizontal frame 21 of the corresponding front and rear side frames.

[0042] The rear seats consist of three sets of seat frames 2, which are connected horizontally to form a whole. Therefore, the middle set of seat frames can share the same vertical frames on both sides. The middle set of seat frames 2 only needs to be provided with a horizontal frame 21 and a vertical frame 22.

[0043] In a preferred example, the middle group seat frame may also be without a longitudinal frame.

[0044] Each seat has cross-connecting support rods between adjacent transverse frames 21, such as... Figure 3 As shown, the support rods between two adjacent transverse frames include a first support rod 4 and a second support rod 5, which are arranged in an X-shape.

[0045] The sides of both ends of the transverse frame 21 are provided with fixing points, such as... Figure 6 As shown, there are first fixing point 211 and second fixing point 212. The fixing structure at the fixing point can be set as an ear plate. The two ends of the support rod are hinged to the ear plate. The hinged connection between the support rod and the transverse frame 21 is the prior art.

[0046] like Figure 3 As shown, each seat includes five transverse frames 21, including two bottom transverse frames 21 for mounting on the slide rail, two transverse frames 21 at the middle height serving as the front and rear support frames for the seat cushion, and one top transverse frame 21 located at the top of the backrest. In the case of a rear seat with three seats, the vertical frames 22 include twelve: four on the front side, four on the rear side, and four on the backrest. The vertical frames on the rear side and backrest are connected together. There are two longitudinal frames located on either side of the entire rear seat, with no longitudinal frames on the seat cushion surface near the center.

[0047] In this embodiment, each seat has a first support rod 4 and a second support rod 5 intersectingly connected to adjacent transverse frames, such as... Figures 3-5 As shown, when the seat frames need to be merged, the seat frames are pushed from right to left in the direction shown in the diagram. To achieve seat merging, the first support rod 4, the second support rod 5, and the transverse frame 21 are all telescopic rod structures. The merged state is as follows. Figure 5 As shown, at this point, all the horizontal frames 21 are contracted to their shortest length, while the lengths of the vertical frames 22 and the longitudinal frames remain unchanged. Since the first support rod 4 and the second support rod 5 are connected in an X-shape between adjacent horizontal frames 21 on each face, the length of the support rods also needs to be shortened after merging. Therefore, the support rods are also set as telescopic rod structures, with the same structural form as the horizontal frames 21, as shown below. Figure 6 and Figure 7 As shown.

[0048] To facilitate the smooth merging of the seat frame 2, two transverse slide rails 1 are installed on the rear floor to cooperate with the bottom transverse frames 21 on the corresponding front and rear sides, pushing the seat frame 2 so that the support rod and transverse frames 21 can extend and retract, thereby merging and extending the rear seats.

[0049] like Figure 3 As shown, since the transverse frames 21 between adjacent rear seats in this embodiment are connected sequentially, the merged state is as follows. Figure 1 As shown, the seats can be combined to one side of the vehicle body; when there are two rear seats, the corresponding structural settings are similar to the three-seat structure mentioned above, and the principle is the same, so it will not be described again.

[0050] In another alternative example, when the three rear seats are independent, each rear seat's seat frame 2 is independently set, and the seat frames 2 of the individual seats are not shared (not shown in the figure). With this structure, when merging the rear seats, the seats can be selectively merged to one or both sides of the vehicle body. When merged to both sides, one side has one set of merged seats, and the other side has two sets of merged seats. When the rear seats are two independent seats, the principle is the same as described above and will not be repeated.

[0051] To ensure safety, a locking component needs to be installed to lock the bottom horizontal frame 21 and the horizontal slide rail 1 to prevent them from sliding relative to each other.

[0052] In this embodiment, the transverse slide rail 1 has a groove-like structure. A bottom transverse skeleton is fitted inside the groove. The ends of the bottom transverse skeleton 21 and the transverse slide rail 1 are provided with through holes at the positions corresponding to the extended positions of the bottom transverse skeleton 21, which are used to cooperate with the locking component to achieve locking.

[0053] The cross section of the transverse slide rail 1 is U-shaped, such as... Figure 3 and Figure 8 As shown, each transverse slide rail 1 is equipped with a bottom transverse frame 21 on the front and rear sides. For locking, the locking assembly includes a fixing plate 6 at the end of the transverse slide rail 1. The fixing plate 6 is perpendicular to the transverse slide rail and is used to seal the end of the transverse slide rail, preventing the frame from detaching from the slide rail. A limiting plate 61 is provided on the side of the fixing plate 6 near the transverse slide rail 1. The limiting plate 61 is parallel to the transverse slide rail. A locking shaft 8 is connected to the through hole of the limiting plate 61 facing the transverse slide rail 1 via a spring 7. A lever 9 is provided at the end of the locking shaft 8. When the spring 7 is compressed, it tends to push the locking shaft 8. After the seat frame 2 is unfolded, the through hole at the extended front end of the bottom transverse frame 21 aligns with the through hole on the transverse slide rail 1. The locking shaft 8 is inserted into the two sets of through holes and locked under the action of the spring 7. When the seats are to be combined, the locking shaft 8 can be disengaged from the through holes on the bottom transverse frame and the transverse slide rail by pushing the lever 9 backward, after which the seat frames can be combined.

[0054] In an optional example, to ensure the stability of the locking assembly, a sleeve-shaped structure is connected to the side of the limiting plate 61 near the transverse slide rail. The front end of the sleeve-shaped structure is open, serving as a sliding channel for the locking shaft 8, and the side is provided with an elongated hole for the lever 9 to extend out, serving as a moving channel for the lever 9.

[0055] It is understood that the locking component is preferably located at the end of the transverse slide rail 1, but it can also be located at any position on the transverse slide rail 1 according to the locking requirements. After the seat frame 2 is assembled, a set of locking components can be provided to achieve locking of the assembled seat frame 2. In this embodiment, through holes can also be provided at the bottom of the vertical frame on the front or rear side to cooperate with the locking shaft, which can be selected as needed.

[0056] like Figure 9 and Figure 10 As shown, the seat frame 2 has a detachable seat cushion and backrest assembly 3 installed on its outer side. When merging the seats, the seat cushion and backrest assembly 3 can be removed or merged directly.

[0057] It should be noted that there are no restrictions on the detachable connection method between the seat cushion and backrest assembly 3 and the frame.

[0058] The seat cushion and backrest assembly 3 includes several cylindrical foam components 31, which are connected by textile fabric 32. The textile fabric 32 can be clamped between the cylindrical foam components 31 after shrinking with the seat frame.

[0059] The cylindrical foam component 31 is made of foam material and designed as a strip-shaped cylinder. The connecting part is made of textile fabric 32, which can reduce the overall volume when folded and folded. The cylindrical foam material can solve the comfort problem when the backrest and seat cushion are extended, and also has a breathable function. When the seat is folded up, the cylindrical foam material shrinks together, and the connecting fabric is sandwiched between the foam materials, which is not affected by space.

[0060] In this embodiment, the rear seats, when combined, can reduce the overall width to one-third of the original width, greatly increasing the rear space.

[0061] In other examples, a backrest angle adjustment mechanism can be added to the rear seat frame, which can be specifically set according to needs, but it is not within the scope of protection of this solution and will not be described in detail.

[0062] Example 2

[0063] In a typical embodiment of the present invention, reference is made to Figures 1-8 As shown, a car has a rear seat inside. The rear floor body has two transverse slide rails 1 for cooperating with the bottom transverse frame 21 of the rear seat. The rear seat adopts the foldable and extendable rear seat structure of Embodiment 1.

[0064] When you need to expand the rear space of the car, you can combine the three rear seats into one seat. When you extend the seat, you can restore it to the original state of three seats. The operation is simple and convenient.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
