Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a folding seat and vehicle. Background Technology
[0002] Currently, to enhance vehicle functionality, the backrests of the rear seats are typically foldable, connecting the space above the seats with the trunk space and increasing trunk capacity. However, existing foldable seats generally only fold the backrests, not the seats themselves, meaning the backrests cannot remain horizontal when fully folded. In some other technologies, while both the backrest and seat cushion can move during folding, the folding structure limits their movement; the seat cushion moves forward while downward, causing the front of the seat to protrude forward and affecting the usable space in front of the seat. Utility Model Content
[0003] A first aspect of this utility model aims to provide a folding chair that solves the problem in the prior art where the backrest moves forward when folded, thus affecting the usable space in the front.
[0004] The second aspect of this utility model aims to solve the problem that the seat back cannot be folded horizontally, resulting in a poor user experience.

[0006] When the seat back is moved from the open position to the folded position in a controlled manner, the six-bar linkage moves the seat cushion from the initial position to behind the initial position.
[0007] Optionally, when the seat backrest is moved in a controlled manner from the folded position to the folded position, the seat cushion is moved from the initial position to below the initial position via the six-bar linkage.
[0008] Optionally, the connection point between the fifth movable link and the fixed link is located in front of the connection point between the third movable link and the fixed link, the connection point between the fourth movable link and the fifth movable link is located above the connection point between the fifth movable link and the fixed link, and the connection point between the third movable link and the fourth movable link is located below the connection point between the third movable link and the fixed link. The rotation direction of the third movable link is opposite to the rotation direction of the fifth movable link, and when the seat back moves from the unfolded position to the folded position, the fourth movable link moves backward under the drive of the third movable link.
[0009] Optionally, when the seat back is in the folded position, the connection point between the fifth movable link and the fourth movable link is located on the line connecting the connection point between the fifth movable link and the fixed link and the connection point between the fourth movable link and the third movable link, or is located above that line.
[0010] Optionally, when the seat back is in the unfolded position, the connection point between the fourth movable link and the fifth movable link is located behind the connection point between the fifth movable link and the fixed link.
[0011] Optionally, when the seat back is in the folded position, the connection point between the third movable link and the fourth movable link is located in front of the connection point between the third movable link and the fixed link.
[0012] Optionally, the connection point between the second movable link and the third movable link is located between the connection point between the third movable link and the fixed link and the connection point between the third movable link and the fourth movable link.
[0013] Optionally, the rotation direction of the first movable link is the same as that of the third movable link, and the rotation angle of the first movable link is greater than that of the third movable link.
[0014] Optionally, the rotation angle of the fifth movable link is greater than the rotation angle of the third movable link.
[0015] Optionally, the seat back is connected to the first movable link or a portion of the seat back forms the first movable link, so that the seat back rotates with the first movable link;
[0016] The seat cushion is connected to the fourth movable link, or a portion of the seat cushion forms the fourth movable link, so that the seat cushion moves with the fourth movable link.
[0017] Optionally, a drive mechanism is also included, which is disposed between the first movable link and the fixed link, for driving the seat back to rotate relative to the fixed link between the folded position and the folded position.
[0018] Optionally, it also includes a seat mounting structure for fixing to the vehicle body, the seat mounting structure forming the fixing link, the seat mounting structure including:
[0019] A support base, which is connected to the vehicle body;
[0020] A first mounting bracket is connected to the front of the support base and extends downward, and the first mounting bracket is rotatably connected to the fifth movable link;
[0021] The second mounting bracket is connected to the rear of the support base and extends upward.

[0022] Optionally, the seat mounting structure further includes a third mounting bracket, which is connected to the support base and located in front of and above the support base.
[0023] In particular, this utility model also provides a vehicle that includes the folding seat described above.
[0024] The folding seat in this solution may include a six-bar linkage mechanism. When the seat back moves from the unfolded position to the folded position in a controlled manner, the six-bar linkage mechanism drives the seat cushion from the initial position to the rear of the initial position, realizing the linkage between the seat back and the seat cushion. This also allows the front of the seat cushion to be utilized after the seat back is folded, thereby avoiding affecting the usable space in the front of the seat cushion.
[0025] In this design, the seat backrest moves controlled from its open position to its folded position. The six-bar linkage mechanism enables the seat cushion to move both backward and downward, thus freeing up space in both the front and upper areas, ultimately increasing both front and upper usable space. Furthermore, by moving the seat cushion backward and downward to free up upper space, the seat backrest is unaffected by the seat cushion when it reaches the folded position, resulting in a completely flat seat backrest. This further enhances usable space, improves the appearance of the luggage compartment when the seat back is folded, and enhances the user experience.
[0026] This solution, by folding down the seat back and completely retracting it into the seat mounting structure, completely covers the seat cushion, making it invisible and eliminating the need for additional decorative parts. This enhances the seat's sophistication and reduces costs.

[0036] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0037] As a specific embodiment of this utility model, such as Figures 1 to 5 As shown, this embodiment provides a folding seat 100. The folding seat 100 may include a six-bar linkage 200. The six-bar linkage 200 may include a fixed link 210, a first movable link 220, a second movable link 230, a third movable link 240, a fourth movable link 250, and a fifth movable link 260. One end of the first movable link 220, the third movable link 240, and the fifth movable link 260 is rotatably connected to the fixed link 210. Both ends of the second movable link 230 are rotatably connected to the first movable link 220 and the third movable link 240, respectively. Both ends of the fourth movable link 250 are rotatably connected to the third movable link 240 and the fifth movable link 260, respectively. When the seat back 300 is controlled to move from an open position to a folded position, the six-bar linkage 200 moves the seat cushion 400 from its initial position to a position behind it.
[0038] In one specific embodiment, the connection point between the first movable link 220 and the fixed link 210 is the same as the connection point between the third movable link 240 and the fixed link 210. In another embodiment, the connection points between the first movable link 220 and the fixed link 210 and the third movable link 240 and the fixed link 210 are not the same. The following description will use the example of the first movable link 220 and the fixed link 210 and the third movable link 240 and the fixed link 210 not being at the same connection point.
[0039] Specifically, in this embodiment, the initial position refers to the position of the seat cushion 400 when the seat back 300 is in the unfolded position, such as... Figure 1 The initial position is where the seat cushion 400 is located. In this embodiment, directional terms such as "front" and "rear" refer to the direction of vehicle movement when the seat is positioned on the vehicle (e.g., forward). Figures 1-4 The left side shown is the front, and the backrest position is the back (as shown in the image). Figures 1-4(The right side shown is the rear). Specifically, the six-bar linkage 200 in this embodiment can be one six-bar linkage 200 disposed on one side of the seat, or two six-bar linkages 200 disposed on both sides. If six-bar linkages 200 are disposed on both sides of the seat, the structures of the six-bar linkages 200 on both sides are radially symmetrically arranged, and the rotational connection points on both sides can be connected by a rotating shaft at each rotational connection point, increasing stability. This embodiment uses one of the six-bar linkages 200 as an example for explanation.
[0040] Specifically, in the six-bar linkage 200 of this embodiment, when the first movable link 220 rotates under the action of an external force, it can drive the second movable link 230 to rotate. The second movable link 230 then drives the third movable link 240 to rotate, the third movable link 240 drives the fourth movable link 250 to move, and the fourth movable link 250 then drives the fifth movable link 260 to rotate. Ultimately, when the first movable link 220 rotates counterclockwise, it drives the fourth movable link 250 to move backward and downward. Specifically, in this embodiment, the seat back 300 is connected to the first movable link 220, or a part of the seat back 300 is formed as the first movable link 220, so that the seat back 300 follows the movement of the first movable link 220. The seat cushion 400 is connected to the fourth movable link 250, or the fourth movable link 250 can be a part of the seat cushion 400, so that the seat cushion 400 follows the movement of the fourth movable link 250.
[0041] Specifically, the folding seat 100 in this embodiment may include a six-bar linkage 200. When the seat back 300 is moved from the folded position to the folded position in a controlled manner, the six-bar linkage 200 drives the seat cushion 400 from the initial position to the rear of the initial position, that is, the seat cushion 400 moves from the initial position to the rear, realizing the linkage between the seat back 300 and the seat cushion 400. This also ensures that after the seat back 300 is folded, the front position of the seat cushion 400 is utilized, thereby avoiding affecting the usable space in the front of the seat cushion 400.
[0042] Specifically, in this embodiment, the subsequent description of the movement of the seat back 300 is essentially equivalent to the description of the movement of the first movable link 220, and similarly, the subsequent description of the movement of the seat cushion 400 is essentially equivalent to the description of the movement of the fourth movable link 250.
[0043] As another specific embodiment of this utility model, under the movement of the six-bar linkage 200, when the seat back 300 moves from the unfolded position to the folded position in a controlled manner, the six-bar linkage 200 drives the seat cushion 400 from the initial position to below the initial position. That is, during the folding process of the seat back 300, the seat cushion 400 moves downward.
[0044] Specifically, when the seat back 300 of this embodiment moves from the folded position to the folded position in a controlled manner, the six-bar linkage 200 enables the seat cushion 400 to move both backward and downward, thereby not only avoiding the front space but also avoiding the upper space, ultimately achieving the purpose of increasing the front and upper usable space.
[0045] In addition, by moving the seat cushion 400 backward and downward, the upper space is made available, and the seat back 300 is not affected by the seat cushion 400 when it reaches the folding position. This allows the seat back 300 to achieve a completely flat state, thereby increasing the usable space and beautifying the appearance of the luggage after the seat back 300 is folded, thus improving the user experience.
[0046] As a specific embodiment of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, when the seat back 300 is in the folded position, the connection point a between the fifth movable link 260 and the fixed link 210 is located in front of the connection point b between the third movable link 240 and the fixed link 210, the connection point c between the fourth movable link 250 and the fifth movable link 260 is located above the connection point a between the fifth movable link 260 and the fixed link 210, and the connection point d between the third movable link 240 and the fourth movable link 250 is located below the connection point b between the third movable link 240 and the fixed link 210. The rotation direction of the third movable link 240 is opposite to the rotation direction of the fifth movable link 260. When the seat back 300 moves from the folded position to the folded position, the fourth movable link 250 moves backward under the drive of the third movable link 240.
[0047] Specifically, in this embodiment, the fifth movable link 260 swings upward and the third movable link 240 swings downward. During the process of the third movable link 240 rotating counterclockwise downward, the fifth movable link 260 rotates clockwise, thereby driving the fourth movable link 250 to move backward and downward, which in turn causes the seat cushion 400 to move backward and downward.
[0048] In a specific embodiment of this utility model, when the seat back 300 is folded, the connection point c between the fifth movable link 260 and the fourth movable link 250 is located on or above the line connecting the connection point a between the fifth movable link 260 and the fixed link 210 and the connection point d between the fourth movable link 250 and the third movable link 240. This ensures that the fourth movable link 250 will not move forward during the entire movement process, avoiding interference between the fourth movable link 250 and the seat cushion 400 and other components during the movement.
[0049] In a specific embodiment of this utility model, when the seat back 300 is in the folded position, the connection point c between the fourth movable link 250 and the fifth movable link 260 is located behind the connection point a between the fifth movable link 260 and the fixed link 210. This design ensures that the front end of the seat cushion 400 does not move upwards during the entire movement, thus avoiding interference between the front end of the seat cushion 400 and other components during movement.
[0050] In a specific embodiment of this utility model, when the seat back 300 is in the folded position, the connection point d between the third movable link 240 and the fourth movable link 250 is located in front of the connection point b between the third movable link 240 and the fixed link 210. This design ensures that the rear of the seat cushion 400 does not move upwards during the entire movement, avoiding interference between the rear end of the seat and other components during movement.
[0051] In a specific embodiment of this utility model, the connection point e between the second movable link 230 and the third movable link 240 is located between the connection point b between the third movable link 240 and the fixed link 210 and the connection point d between the third movable link 240 and the fourth movable link 250.
[0052] In this embodiment, the first movable link 220, the second movable link 230, the third movable link 240, and the fixed link 210 can form a four-bar linkage. When the first movable link 220 moves in a controlled manner, it can drive the third movable link 240 to move. The connection point e between the second movable link 230 and the third movable link 240 is located between the connection point b between the third movable link 240 and the fixed link 210 and the connection point d between the third movable link 240 and the fourth movable link 250. On the one hand, the force of the second movable link 230 driving the third movable link 240 to move drives the fourth movable link 250 to move. On the other hand, it can drive the fourth movable link 250 to move a larger stroke with a smaller movement space, thereby satisfying the requirement that when the seat back 300 rotates, the seat cushion 400 is completely retracted to the lower position.
[0053] Specifically, during the process of moving the seat back 300 from an open state to a folded state, its rotation angle is generally greater than 90°. However, the seat cushion 400 is constrained by space during movement, and the rotation angles of the third movable link 240 and the fifth movable link 260 are generally not greater than 90°. In this embodiment, to achieve the desired effect, the rotation angle of the first movable link 220 is greater than that of the third movable link 240, and the rotation angle of the fifth movable link 260 is greater than that of the third movable link 240. For example, in one embodiment, the rotation angle of the first movable link 220 can reach 113°, while the rotation angle of the third movable link 240 is only 44°, and the rotation angle of the fifth movable link 260 is only 62°. Specifically, the rotation angle can be designed according to the actual spatial position.
[0054] More specifically, the rotation angle in the movable link can be designed according to the length of the movable link; generally, the longer the movable link, the smaller the rotation angle. For example, when the rotation angle of the first movable link 220 is greater than the rotation angle of the third movable link 240, the length of the first movable link 220 only needs to be designed to be less than the distance between the connection point e between the third movable link 240 and the second movable link 230 and the connection point b between the third movable link 240 and the fixed link 210. Similarly, if the rotation angle of the fifth movable link 260 is greater than the rotation angle of the third movable link 240, the length of the fifth movable link 260 can be designed to be greater than the distance between the connection point d between the third movable link 240 and the fourth movable link 250 and the connection point b between the third movable link 240 and the fixed link 210.
[0055] As a specific embodiment of the present invention, the folding seat 100 of this embodiment may further include a drive mechanism 500, which is disposed between the first movable link 220 and the fixed link 210, for driving the first movable link 220 and the seat back 300 to rotate between the unfolded position and the folded position.
[0056] Specifically, in this embodiment, the drive mechanism 500 can be a combination of a motor and a gear mechanism. The motor is located at the fixed connecting rod 210, and the gear mechanism can include a meshing driving gear and a driven gear. The driving gear is connected to the output shaft of the motor and rotates under the motor's drive. The driven gear is connected to the first movable connecting rod 220 or the seat back 300. The driving gear drives the driven gear to rotate, thereby driving the seat back 300 to rotate. By controlling the motor, the seat back 300 can rotate between an open position and a folded position.
[0057] As a specific embodiment of this utility model, the folding seat 100 of this embodiment may further include a seat mounting structure 600 fixed to the vehicle body, the seat mounting structure 600 forming a fixed link 210. The seat mounting structure 600 may include a support base 610, a first mounting bracket 620, and a second mounting bracket 630. The support base 610 may be substantially horizontally positioned and fixed to the vehicle body. The first mounting bracket 620 is connected to the front of the support base 610 and extends downwards, and is rotatably connected to a fifth movable link 260. The second mounting bracket 630 is connected to the rear of the support base 610 and extends upwards, the second mounting bracket 630 is rotatably connected to a third movable link and a first movable link 220, and the connection point between the second mounting bracket 630 and the third movable link 240 is located behind and below the connection point between the second mounting bracket 630 and the backrest frame.
[0058] Specifically, in this embodiment, the seat mounting structure 600 is fixed to the vehicle body and can serve as the fixed link 210 of the six-bar linkage 200. The first mounting bracket 620 can be used to rotatably connect with the fifth movable link 260. The first mounting bracket is positioned below the support base 610 to ensure that the seat cushion 400 is retracted into the space below during movement. The second mounting bracket 630 is positioned behind the support base 610 and extends upward to ensure the compactness of the six-bar linkage 200 structure.
[0059] As a specific embodiment of this utility model, such as Figures 1-4 As shown, the seat mounting structure 600 of this embodiment also includes a third mounting bracket 640, which is connected to the support base 610 and located in front of and above the support base 610. Specifically, the third mounting bracket 640 of this embodiment is configured such that when the seat back 300 is in the folded position, the front of the seat cushion 400 is located above the third mounting bracket 640. The third mounting bracket 640 provides a certain support force to the seat cushion 400, preventing the seat cushion 400 and the force above it from being applied entirely to the six-bar linkage 200, which would cause the linkage to bear too much weight and deform or be damaged, thus improving the service life of the six-bar linkage 200. When the seat back 300 is in the folded position, the seat cushion 400 is located behind the third mounting bracket 640, and the highest point of the seat cushion 400 is not higher than the highest point of the third mounting bracket 640. This ensures that the entire seat cushion 400 can be completely stored within the seat mounting structure 600, making it invisible and eliminating the need for additional decorative parts to cover it, thus enhancing the seat's refinement and reducing costs.
[0060] As a specific embodiment of this utility model, this embodiment also provides a vehicle that may include the aforementioned folding seat 100. In a vehicle with the aforementioned folding seat 100, the seat back 300 can be folded down. When the seat back 300 is folded, the seat cushion 400 moves backward and downward, without occupying the space in front of the seat cushion 400. Furthermore, the seat back 300 is completely horizontal in the folded state, improving the usability of the entire trunk and extended space. Additionally, when the seat back 300 is fully folded, the seat cushion 400 is completely hidden beneath the seat back 300, saving space and remaining invisible, eliminating the need for additional decorative elements and reducing costs.
[0061] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
