[0002] Currently, the interior space of single-row light trucks can only accommodate three people at most. The seat cushions of existing single-row light trucks are approximately 420mm wide from front to back, leaving no room for reclining. Users can only lie horizontally on the single-row seats. However, due to the narrow seat cushion width and the approximately 490mm shoulder width of a person, when a person lies completely horizontally, part of the body will be suspended in the air, making lying flat uncomfortable and prone to falling to the floor when rolling over, posing a safety hazard. Therefore, such single-row light trucks are only suitable for reclining and taking a nap. Currently, most cars mainly adjust the backrest backward to achieve the purpose of reclining. However, for single-row light trucks, due to limited space and lack of space for adjusting the backrest backward, this backrest adjustment method is not suitable for such compact single-row light trucks. Therefore, it is more important to design a folding seat suitable for single-row light trucks in small spaces. Summary of the Invention

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0016] like Figure 1 and Figure 2 As shown, a folding seat for a vehicle includes an upper seat cushion 1, a lower seat cushion 2 and a folding mechanism 3. The upper seat cushion 1 and the lower seat cushion 2 are used in combination to have an unfolding mode and a folding mode. The upper seat cushion 1 and the lower seat cushion 2 are respectively connected to the folding mechanism 3. The folding mechanism 3 is used to change the upper seat cushion 1 and the lower seat cushion 2 between a folding mode and an unfolding mode; in the folding mode, the upper seat cushion 1 is located above the lower seat cushion 2 and serves as an ordinary seat; in the unfolding mode, the upper seat cushion 1 moves forward to the front side and the lower seat cushion 2 moves upward to the top, and the upper seat cushion 1 is located in front of the lower seat cushion 2. The upper seat cushion 1 and the lower seat cushion 2 cooperate to serve as a reclining chair. At this time, the width of the seat is the sum of the widths of the upper seat cushion 1 and the lower seat cushion 2.

[0017] This application utilizes the leg activity area in front of the seat to provide space for the seat cushion to unfold, thereby increasing the width of the seat to meet the needs of lying flat in the berth.

[0018] The folding mechanism 3 includes folding devices arranged side by side on the left and right sides, and the two sides of the upper seat cushion 1 and the lower seat cushion 2 are respectively connected to the folding devices on the left and right sides. The folding device is the key device to realize the change of the upper seat cushion 1 and the lower seat cushion 2 between the folded mode and the unfolded mode.

[0019] See also Figure 3 The folding device includes a support base 31, an upper hinge part 32, an upper support plate 33, a lower hinge part 34, and a lower support plate 35, wherein the support base 31 serves as a supporting structure, and its bottom end is supported by support legs and fixed on the vehicle body. The support base 31 is integrally formed and has a better supporting effect.

[0020] See also Figures 3 to 9 When the folding mode is in folding, the upper support plate 33 is located at the upper rear side of the support seat 31, and the lower support plate 35 is located at the lower rear side of the support seat 31; when the folding mode is in folding, the upper support plate 33 is located at the upper front side of the support seat 31, and the lower support plate 35 is located at the upper rear side of the support seat 31. Through reasonable arrangement, the upper support plate 33 can be swung forward and backward from above the support seat 31, and the lower support plate 35 can be swung up and down from behind the support seat 31, ensuring that the upper support plate 33 and the lower support plate 35 do not interfere with each other when changing modes. When changing from the folding mode to the unfolding mode, the upper support plate 33 located at the upper rear is first swung forward to the upper front, and then the lower support plate 35 below is swung backward to the upper rear. At this time, the lower seat cushion 2 is located behind the upper seat cushion 1, and the surfaces of the two are almost parallel, splicing into a berth chair with double width, which can turn a single row of seats in a light truck into a double row of seats, making it convenient for users to lie down. When changing from the unfolding mode to the folding mode, the lower support plate 35 located at the upper rear is first swung backward to the initial position at the lower bottom, and then the upper support plate 33 located at the upper front is swung backward to the initial position at the upper rear. At this time, the lower seat cushion 2 is located above the upper seat cushion 1, and the folded width is the width of a single seat cushion.

[0021] The upper hinge member 32 includes an upper front rod 32a and an upper rear rod 32b, and the support seat 31, the upper support plate 33, the upper front rod 32a and the upper rear rod 32b form a parallelogram, and the support seat 31 is horizontal with the upper support plate 33. The upper support plate 33 adopts a parallelogram method to move forward and backward in a horizontal posture, ensuring that the upper seat cushion 1 is always horizontal in the folding mode and the unfolding mode; the lower hinge member 34 includes a lower front rod 34a and a lower rear rod 34b, and the support seat 31, the lower support plate 35, the lower front rod 34a and the lower rear rod 34b form a parallelogram, and the support seat 31 is horizontal with the lower support plate 35. The lower support plate 35 adopts a parallelogram method to move up and down in a horizontal posture, ensuring that the lower seat cushion 2 is always horizontal in the folding mode and the unfolding mode.

[0022] The bottom end of the upper front rod 32a is connected to the inner side of the support seat 31 through a pin 1 36, the bottom end of the upper rear rod 32b is connected to the outer side of the support seat 31 through a pin 2 37, and the upper support plate 33 is connected to the top ends of the upper front rod 32a and the upper rear rod 32b through a pin 38 and a pin 4 39; one end of the lower front rod 34a is connected to the inner side of the support seat 31 through a pin 1 36, one end of the lower rear rod 34b is connected to the inner side of the support seat 31 through a pin 2 37, and the lower support plate 35 is connected to the other ends of the lower front rod 34a and the lower rear rod 34b through a pin 5 310 and a pin 6 311. In this embodiment, the upper front rod 32a and the lower rear rod 34b are close to the inner surface of the support seat 31, and the upper front rod 32a and the lower rear rod 34b are located in the same horizontal plane, the upper end of the lower front rod 34a is located on the inner surface of the upper front rod 32a, and the lower end of the lower front rod 34a is bent inward and is in the same plane as the lower rear rod 34b, which is used to connect the lower support plate 35; the bottom end of the upper rear rod 32b is close to the outer surface of the support seat 31, and the top end of the upper rear rod 32b is bent inward and is in the same plane as the upper front rod 32a, which is used to connect the upper support plate 33.

[0023] The first and second pins 36 and 37 are provided with a rotational damping structure. This is a conventional flexible rotational damping structure used in a central axis, which is publicly available and will not be described in detail here. The rotational damping structure primarily acts as a resistance and deceleration mechanism, increasing resistance between the folded and unfolded states to prevent arbitrary state changes.

[0024] In order to ensure that the upper seat cushion 1 and the lower seat cushion 2 can be stably supported in the folding mode and the unfolding mode, it is necessary to set a positioning structure in the folding mode and the unfolding mode respectively. The positioning structure includes an upper folding positioning structure, a lower folding positioning structure, an upper unfolding positioning structure, and a lower unfolding positioning structure. The upper folding positioning structure, the lower folding positioning structure, the upper unfolding positioning structure, and the lower unfolding positioning structure are used together to ensure the stable positioning of the upper seat cushion 1 and the lower seat cushion 2 in the folding mode and the unfolding mode without affecting the seat function and the reclining function.

[0025] By utilizing the design feature that the upper front rod 32a and the lower rear rod 34b are located in the same plane, when in the folding mode, the upper front rod 32a is pressed downwardly against the lower rear rod 34b as an upper folding positioning structure, and the upper front rod 32a is supported by the upper front rod 32a pressed against the lower rear rod 34b. Figure 4, achieving the purpose of limiting, so that the upper support plate 33 and the upper seat cushion 1 thereon can be stably stopped in the folding mode. During the driving of the vehicle, the upper front rod 32a has no tendency to rotate forward, and when someone sits on the upper seat cushion 1 and applies downward pressure, the upper front rod 32a still provides stable support by pressing against the lower rear rod 34b.

[0026] The support seat 31 is provided with a lower positioning block 312 on the front side of the lower front rod 34a or the lower rear rod 34b. In the folding mode, the front side of the lower front rod 34a and the lower rear rod 34b abuts against the lower positioning block 312 as a lower folding positioning structure. At this time, the angle between the lower rear rod 34b and the lower support plate 35 is α Less than 90°, see Figure 6 Under the action of gravity, the lower rear rod 34b and the lower front rod 34a will automatically rest against the lower positioning block 312 to achieve the purpose of limiting the position, and when the vehicle moves forward, the lower rear rod 34b and the lower front rod 34a have a smaller shaking amplitude and are close to being stationary. The cooperation relationship between the lower positioning block 312 and the lower front rod 34a and the lower rear rod 34b is used to ensure that the lower support plate 35 and the lower seat cushion 2 thereon can be stably kept close to being stationary in the folded mode.

[0027] The rear end of the upper support plate 33 is provided with an upper positioning pressing block 313 corresponding to the upper rear rod 32b. The upper positioning pressing block 313 is located above the upper rear rod 32b, so that in the expanded mode, the upper positioning pressing block 313 can be pressed against the upper rear rod 32b as an upper expansion positioning structure, and the upper support plate 33 is supported by the upper positioning pressing block 313 pressed against the upper rear rod 32b. Figure 7 , achieving the purpose of limiting, so that the upper support plate 33 and the upper seat cushion 1 thereon can be stably stopped in the expanded state. When someone lies down on the upper seat cushion 1 and applies downward pressure, the upper positioning block 313 still presses downward from the upper rear rod 32b for stable support.

[0028] The lower front rod 34a is provided with a lower positioning block 314 corresponding to the upper rear rod 32b. In the deployment mode, the lower front rod 34a and the lower rear rod 34b are tilted forward to a greater than 90° angle from the support seat 31, and the lower positioning block 314 is pressed against the upper rear rod 32b to serve as a lower deployment positioning structure. In the deployment mode, the angle β between the lower front rod 34a and the support seat 31 is greater than 90°. Figure 9Under the action of gravity, the lower positioning block 314 of the lower front rod 34a is located on the upper part of the upper rear rod 32b, and will automatically press against the upper rear rod 32b to achieve the purpose of limiting, so that the lower support plate 35 and the lower seat cushion 2 thereon can be stably stopped in the unfolded state. When someone lies down on the lower seat cushion 2 and applies downward pressure, the lower positioning block 314 still presses downward from the upper side against the upper rear rod 32b for stable support.

[0029] The upper front rod 32a is in a bent form and includes a lower long rod and an upper short rod, and the upper rear rod 32b is in a bent form and includes a lower short rod and an upper long rod. In this embodiment, the lower long rod is parallel to the upper long rod, and the upper short rod is parallel to the lower short rod.

[0030] In the folding mode, the upper seat cushion 1 is located directly above the lower seat cushion 2 to reduce the space occupied. In order to ensure that the upper seat cushion 1 is located directly in front of the lower seat cushion 2 after unfolding, the upper seat cushion 1 is spliced ​​to form a berth recliner. Therefore, the rear side of the upper seat cushion 1 is connected to the upper support plate 33, and the front side of the lower seat cushion 2 is connected to the lower support plate 35. In order to facilitate the movement of the lower seat cushion 2, the two lower support plates 35 need to be located on the inner side of the two support seats 31, so that the lower seat cushion 2 is located on the inner side of the two support seats 31. See the state for details. Figure 10 At this time, the movements of the upper seat cushion 1 and the lower seat cushion 2 do not interfere with each other.

[0031] In order to facilitate the user to switch modes, an operating pull rope can be installed on the side ends of the upper seat cushion 1 and the lower seat cushion 2. The operating pull rope can be set on one commonly used side end or both sides.

[0032] The front-to-back width and left-to-right width of the upper seat cushion 1 are consistent with the width of a single-row seat in a single-row light truck. The front-to-back width and left-to-right width of the lower seat cushion 2 can be designed based on the interior space of the vehicle and appropriately positioned relative to the upper seat cushion 1. In this embodiment, the front-to-back width and left-to-right width of the lower seat cushion 2 are kept consistent with those of the upper seat cushion 1, thereby doubling the left-to-right width in the expanded mode.

[0033] The working principle of this embodiment is: See also Figure 1 、 Figures 4 to 63 is a schematic diagram of the state in the folding mode. At this time, the upper support plate 33 is located above the rear side of the support seat 31, the lower support plate 35 is located below the support seat 31, and the upper seat cushion 1 is located above the lower seat cushion 2. As a normal seat, the upper front rod 32a is pressed against the lower rear rod 34b to limit the upper seat cushion 1, and the lower front rod 34a and the lower rear rod 34b are pressed against the lower positioning block 312 to limit the lower seat cushion 2 and keep it in the folded position. When used as a normal seat, the seat width is the width of a single seat cushion, which is no different from a single-row seat in a single-row light truck model, and is used for users to sit. When it is necessary to unfold, first lift the upper cushion 1 upwards and swing it forward to the front upper part, so that the upper positioning block 313 presses against the upper rear rod 32b and stops, then lift the lower cushion 2 backwards and swing it backwards to the rear upper part, so that the lower positioning block 314 presses against the upper rear rod 32b and stops. Figures 7 to 9 At this time, the lower seat cushion 2 is located behind the upper seat cushion 1, and the surfaces of the two are almost parallel. The upper seat cushion 1 and the lower seat cushion 2 are spliced ​​together to form a double-width sleeper chair, which can turn a single-row seat in a light truck into a double-row seat, making it convenient for users to lie down; When the user needs to fold the seat cushion, the user just needs to do the reverse operation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
