Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a seat that can achieve forward folding of the seat cushion and flattening of the backrest. Background Technology

[0002] As a key component of automotive interiors, car seats directly impact the comfort of passengers and play a crucial role in the effective utilization of interior space. With the continuous development of the automotive industry and the increasing diversification of consumer demands, people are placing higher demands on car seats. They not only expect excellent comfort but also more practical functions to meet the needs of different scenarios, especially in terms of space utilization, with consumers showing a continuously increasing demand for trunk space. Currently, a common way to expand trunk space is to fold the car seat back forward, making it flush with the rear trunk surface, thus creating a relatively regular and large storage space. However, in practical applications, the structural design of some car seats has certain limitations, making it impossible to directly achieve the function of folding the backrest forward. Specifically, folding the backrest forward is restricted by the seat cushion, and the arrangement space between the two conflicts. Therefore, users need to manually lift the seat cushion first to make room for the backrest to fold, and then fold the backrest down, which is a laborious and time-consuming operation. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a seat that can achieve forward folding of the seat cushion and flattening of the backrest, without manual operation, and the seat cushion and backrest can be automatically folded.

[0004] To achieve the above objectives, this utility model proposes a seat capable of folding the seat cushion forward and flattening the backrest, including a backrest and a seat cushion. The lower ends of the backrest are rotatably connected to the rear end of the seat cushion via backrest angle adjusters. The backrest angle adjusters are equipped with backrest angle adjuster motors, which drive the backrest angle adjusters to fold the backrest forward. The seat cushion also includes an upper support bracket, the rear end of which is supported on the seat cushion. The front end of the upper support bracket is rotatably connected to the seat cushion via a linkage mechanism. The linkage mechanism is equipped with a drive mechanism. When the drive mechanism is working, it drives the linkage mechanism to move, thereby causing the upper support bracket to rotate counterclockwise and open to provide space for the backrest to flatten. At this time, the backrest angle adjuster motor drives the backrest angle adjuster to fold the backrest forward.

[0005] In the above scheme: the linkage mechanism includes a seat cushion central axis bracket, two seat cushion linkage brackets, and two seat cushion front fixing brackets. The two seat cushion linkage brackets and the two seat cushion front fixing brackets are symmetrically arranged left and right. The lower ends of the two seat cushion front fixing brackets are rotatably connected to the front sides of the seat cushion via seat cushion adjusters. The two seat cushion adjusters are connected by a seat cushion linkage rod. The driving mechanism is a seat cushion adjuster motor, which is mounted on the seat cushion linkage rod and fixed to the seat cushion. The middle portions of the two seat cushion front fixing brackets are hinged to the rear sides of the seat cushion central axis bracket, and the upper ends of the two seat cushion front fixing brackets are respectively connected to the middle portions of the corresponding side seat cushion linkage brackets. The seat cushion is hinged, and the left and right ends of the seat cushion are provided with sliding grooves extending forward and backward. The rear ends of the two seat cushion connecting rod brackets are slidably connected to the corresponding side sliding grooves and can rotate along the sliding grooves. The front ends of the two seat cushion connecting rod brackets are respectively hinged to the front ends of the upper seat cushion bracket. The front ends of the upper seat cushion bracket are respectively hinged to the front ends of the central seat cushion bracket. When the seat cushion adjuster motor is working, it can drive the seat cushion adjuster to run, thereby driving the front fixed bracket of the seat cushion to rotate counterclockwise relative to the seat cushion, and driving the seat cushion connecting rod bracket to move forward along the sliding groove, and driving the central seat cushion bracket to move forward, thereby driving the upper seat cushion bracket to flip and open counterclockwise.

[0006] The linkage mechanism, consisting of the seat cushion central support, seat cushion connecting rod support, and seat cushion front fixed support, uses hinged and sliding connections between components to form a stable and clear motion transmission path. When the seat cushion adjuster motor is working, it can precisely drive the seat cushion adjuster to operate, thereby causing the seat cushion front fixed support to rotate counterclockwise relative to the seat cushion. This rotation, through the coordinated action of the linkage mechanism, sequentially drives the seat cushion connecting rod support to move forward along the slide, the seat cushion central support to move forward, and finally causes the seat cushion upper support to flip and open counterclockwise. The entire movement process is smooth and orderly, and the precise coordination between the components ensures the accuracy and stability of the seat cushion's forward flipping action, avoiding shaking or jamming during the movement.

[0007] In the above solution: a backrest linkage rod connects the two backrest adjusters, and the backrest adjuster motor is mounted on the backrest linkage rod and fixed to the backrest. The two backrest adjusters are connected by the backrest linkage rod, so that a single backrest adjuster motor can simultaneously drive the backrest adjusters on both sides.

[0008] In the above solution: the upper support of the seat cushion is hinged to the front end of the seat cushion connecting rod support through an L-shaped connecting foot plate, and the connecting foot plate and the upper support of the seat cushion are fixed by welding. The front end of the upper support of the seat cushion has two vertical lugs on the left and right sides respectively. The vertical lugs extend downwards, and the lower ends of the two vertical lugs are respectively hinged to the front end of the corresponding side of the seat cushion central axis support. The structure is simple, the layout is convenient, and it is conducive to ensuring the coordinated movement between the various parts of the seat.

[0009] In the above solution: the seat cushion central support includes a rotating shaft, which is rotatably connected between the middle of the two seat cushion front fixed supports. Two horizontal supports are arranged opposite each other on the rotating shaft. The horizontal supports extend forward, and the front ends of the two horizontal supports are hinged to the lower ends of the two vertical supports. The structure is simple and easy to install.

[0010] In the above scheme: the front fixing bracket of the seat cushion is arranged diagonally with the front lower and the back higher, which makes it easy to design a specific movement trajectory to achieve the forward flip of the seat cushion.

[0011] In the above solution: the seat cushion is welded to the inner side of the seat cushion adjuster, the front fixing bracket of the seat cushion is welded to the outer side of the seat cushion adjuster, the backrest is welded to the inner side of the backrest adjuster, and the seat cushion is welded to the outer side of the backrest adjuster. The inner and outer sides of both the seat cushion adjuster and the backrest adjuster can rotate relative to each other. Through this relative rotation, the seat cushion adjuster can drive the upper bracket of the seat cushion to adjust its angle, such as tilting it forward, and the backrest adjuster can drive the backrest to flatten or adjust its angle.

[0012] The beneficial effects of this utility model are as follows: 1. This seat, equipped with a seat cushion support, a linkage mechanism, and a corresponding drive mechanism, can automatically achieve the forward flipping action of the seat cushion (essentially referring to the forward flipping of the seat cushion support). When it is necessary to expand the luggage space, the drive mechanism drives the linkage mechanism to move, causing the seat cushion support to flip counterclockwise and open, providing ample space for the backrest to flatten. Subsequently, the backrest angle adjuster motor drives the backrest angle adjuster to operate, causing the backrest to flatten forward. The entire process does not require manual lifting of the seat cushion and folding down of the backrest, realizing the automated operation of seat space expansion, greatly improving the convenience and efficiency of operation, and saving users' time and energy. 2. Traditional seats are limited by the seat cushion when the backrest is flattened, which prevents the backrest from directly folding forward, thus limiting the expansion of luggage space. However, this seat, through its unique structural design, cleverly solves the space conflict problem between the seat cushion and the backrest, enabling the backrest to be completely flattened within a limited space, making the backrest flush with the rear luggage compartment surface of the vehicle body, thereby effectively expanding the luggage space, meeting users' needs for larger luggage space, and improving the space utilization efficiency of the car.

[0021] like Figure 1 As shown in Figure 8, a type of seat that can flip the seat cushion forward and flatten the backrest mainly consists of a backrest 1, a seat cushion 2, and a seat cushion support 5.

[0022] The lower ends of the backrest 1 are rotatably connected to the rear end of the seat cushion 2 via backrest angle adjusters 4. The backrest angle adjuster 4 is equipped with a backrest angle adjuster motor 3, which can drive the backrest angle adjuster 4 to fold the backrest 1 forward.

[0023] The rear end of the seat cushion support 5 is supported on the seat cushion 2, and the front end of the seat cushion support 5 is rotatably connected to the seat cushion 2 through a linkage mechanism. The linkage mechanism is equipped with a drive mechanism. When the drive mechanism is working, it can drive the linkage mechanism to move, thereby causing the seat cushion support 5 to rotate counterclockwise and open, providing space for the backrest 1 to be flattened. At this time, the backrest angle adjuster motor 3 drives the backrest angle adjuster 4 to run, which can drive the backrest 1 to be flattened forward.

[0024] Note: The forward tilting of the seat cushion implemented in this article actually refers to the forward tilting of the seat cushion support 5.

[0025] Ideally, the linkage mechanism includes a seat cushion central support 6, two seat cushion linkage supports 7, and two seat cushion front fixing supports 8. The two seat cushion linkage supports 7 and the two seat cushion front fixing supports 8 are symmetrically arranged left and right. The lower ends of the two seat cushion front fixing supports 8 are rotatably connected to the front sides of the seat cushion 2 via seat cushion adjusters 10. The two seat cushion adjusters 10 are connected by a seat cushion linkage rod 9. The driving mechanism is a seat cushion adjuster motor 12, which is mounted on the seat cushion linkage rod 9 and fixed to the seat cushion 2. The two seat cushion front fixing supports 8... The middle part is hinged to the rear sides of the seat cushion central axis bracket 6. The upper ends of the two seat cushion front fixed brackets 8 are respectively hinged to the middle of the corresponding side seat cushion connecting rod brackets 7. The left and right ends of the seat cushion 2 are respectively provided with front and rear extending slide grooves 21. The rear ends of the two seat cushion connecting rod brackets 7 are respectively slidably connected to the corresponding side slide grooves 21 by step bolts or rivets, and can rotate along the slide grooves 21. The front ends of the two seat cushion connecting rod brackets 7 are respectively hinged to the front sides of the upper seat cushion bracket 5. The frontmost two sides of the upper seat cushion bracket 5 are respectively hinged to the front sides of the seat cushion central axis bracket 6.

[0026] When the seat cushion adjuster motor 12 is working, it can drive the seat cushion adjuster 10 to run, thereby causing the front fixed bracket 8 of the seat cushion to rotate counterclockwise relative to the seat cushion 2, and causing the seat cushion connecting rod bracket 7 to move forward along the slide groove 21, and also causing the seat cushion central shaft bracket 6 to move forward, thereby causing the upper bracket 5 of the seat cushion to flip and open counterclockwise.

[0027] The system utilizes a linkage mechanism consisting of the seat cushion central support 6, the seat cushion connecting rod support 7, and the seat cushion front fixed support 8. These components are connected by hinges and sliding joints, creating a stable and clearly defined motion transmission path. When the seat cushion adjuster motor 12 operates, it precisely drives the seat cushion adjuster 10, causing the seat cushion front fixed support 8 to rotate counterclockwise relative to the seat cushion 2. This rotation, through the coordinated action of the linkage mechanism, sequentially drives the seat cushion connecting rod support 7 forward along the slide groove 21, then the seat cushion central support 6 forward, ultimately causing the seat cushion upper support 5 to flip and open counterclockwise. The entire movement is smooth and orderly, with precise coordination between components, ensuring the accuracy and stability of the seat cushion 2's forward flipping action and preventing shaking or jamming during movement.

[0028] Ideally, a backrest linkage rod 11 connects the two backrest adjusters 4, and the backrest adjuster motor 3 is mounted on the backrest linkage rod 11 and fixed to the backrest 1. The two backrest adjusters 4 are connected by the backrest linkage rod 11, so that a single backrest adjuster motor 3 can drive the backrest adjusters 4 on both sides simultaneously.

[0029] Ideally, the upper support 5 of the seat cushion is hinged to the front end of the seat cushion connecting rod support 7 via an L-shaped connecting foot plate 51, and the connecting foot plate 51 is fixed to the upper support 5 of the seat cushion by welding. The front end of the upper support 5 of the seat cushion has two vertical lugs 52 facing each other on the left and right. The vertical lugs 52 extend downwards, and the lower ends of the two vertical lugs 52 are respectively hinged to the front end of the corresponding side of the seat cushion central axis support 6. The structure is simple, the layout is convenient, and it is conducive to ensuring the coordinated movement between the various parts of the seat.

[0030] Ideally, the seat cushion central support 6 includes a rotating shaft 61, which is rotatably connected between the middle of the two seat cushion front fixed supports 8. Two horizontal supports 62 are arranged on the rotating shaft 61 in opposite directions. The horizontal supports 62 extend forward, and the front ends of the two horizontal supports 62 are hinged to the lower ends of the two vertical supports 52. The structure is simple and easy to install.

[0031] Ideally, the front fixing bracket 8 of the seat cushion should be arranged diagonally with the front lower and the back higher, which makes it easier to design a specific movement trajectory to achieve the forward flip of the seat cushion 2.

[0032] Ideally, the seat cushion 2 is welded to the inner side of the seat cushion adjuster 10, the front fixing bracket 8 of the seat cushion is welded to the outer side of the seat cushion adjuster 10, the backrest 1 is welded to the inner side of the backrest adjuster 4, and the seat cushion 2 is welded to the outer side of the backrest adjuster 4. The inner and outer sides of the seat cushion adjuster 10 and the backrest adjuster 4 can both rotate relative to each other. Through this relative rotation, the seat cushion adjuster 10 can drive the upper bracket 5 of the seat cushion to perform angle adjustments such as forward tilting, and the backrest adjuster 4 can drive the backrest 1 to flatten or adjust its angle.
