Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a seating, a vehicle, and a seating control method. Background Technology

[0002] With the gradual development of automotive technology, vehicle seating typically features a folding function. For example, a seat includes a cushion and a backrest, with the bottom end of the backrest hinged to the cushion. The backrest can rotate to an unfolded state relative to the cushion and to a folded state covering the cushion. Because the backrest has a certain thickness, interference occurs between the backrest and the cushion in the folded state, potentially causing an angle between them and affecting the aesthetic appeal. Summary of the Invention

[0003] This application provides a seating, a vehicle, and a seating control method that enables the backrest and seat cushion to be parallel in the folded state, thereby improving the decorative effect of the seating in the folded state.

[0004] In a first aspect, a seating arrangement is provided, comprising: a seat cushion, a backrest cushion, and a compression device, wherein the backrest is erected at one end of the seat cushion, and the end of the backrest near the seat cushion is hinged to the seat cushion so that the backrest can be switched between a folded state and an unfolded state, wherein the backrest covers the seat cushion in the folded state; at least one of the backrest and the seat cushion is provided with a cushion, and the compression device is connected to the cushion and is used to reduce the thickness of the cushion.

[0005] With the above configuration, at least one of the backrest and seat cushion is equipped with the cushioning pad. A compression device is connected to the cushioning pad and is used to reduce the thickness of the cushioning pad. The compression device can reduce the thickness of the cushioning pad, thereby reducing the thickness of at least one of the backrest and seat cushion. When the backrest rotates to the seat cushion, because the thickness of at least one of the backrest and seat cushion is reduced, interference between the backrest and seat cushion can be avoided. This allows the backrest in the folded state to be approximately parallel to the seat cushion, and the backrest will not tilt relative to the seat cushion, thus improving the decorative effect of the seat in the folded state. On the other hand, since the backrest is approximately parallel to the seat cushion in the folded state, the space occupied by the seat in the folded state can also be reduced, increasing the vehicle's storage space.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the backrest and seat cushion can also be connected by an adjustment device. This adjustment device can adjust the rotation angle of the backrest about a hinge axis to adjust the tilt of the backrest relative to the seat cushion, thereby improving seating comfort. For example, the adjustment device may include a motor, a drive gear, and a driven gear. The drive gear is driven by the motor's main shaft, and the driven gear is driven by the backrest; the drive gear and driven gear mesh. During backrest adjustment, the motor drives the drive gear to rotate, which in turn drives the backrest to rotate via the driven gear.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the backrest can be switched between an unfolded and folded state by driving the backrest to rotate via an adjusting device. In other examples, the backrest can be switched between the unfolded and folded states by manually pushing it. When the backrest is switched between the unfolded and folded states, the adjusting device can be disengaged from the backrest, for example, by disengaging the driving gear from the driven gear, or by disengaging the driven gear from the backrest.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the seat cushion includes a first support, and a backrest is hinged to the first support; a cushioning pad is disposed on the first support; in the folded state, the cushioning pad is located between the first support and the backrest. The cushioning pad may include at least one of sponge, polyurethane foam, and latex, and the cushioning pad has good flexibility and resilience; when riding, the occupant can sit on the cushioning pad to improve riding comfort.

[0009] With the above settings, before or during the rotation of the backrest from the unfolded state to the folded state, the compression device can compress the cushioning pad to reduce the thickness of the cushioning pad, thereby reducing the thickness of the seat cushion, avoiding interference between the backrest and the seat cushion, so that the backrest is roughly parallel to the seat cushion in the folded state.

[0010] In the example where the compression device compresses the cushioning pad during the backrest's rotation from an unfolded to a folded state, the compression device can compress the cushioning pad before the backrest comes into contact with it, thus avoiding affecting the backrest's rotation. Alternatively, the compression device can compress the cushioning pad simultaneously with the backrest contacting it, in which case the backrest and the compression device work together to compress the cushioning pad, with the backrest providing assistance to the compression device in compressing the cushioning pad.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the backrest includes a second support hinged to the seat cushion; a cushioning pad is disposed on the second support; in the folded state, the cushioning pad is located between the second support and the seat cushion. The cushioning pad has good flexibility and resilience; when seated, the occupant can lean against the cushioning pad to improve seating comfort.

[0012] With the above settings, before or during the rotation of the backrest from the unfolded state to the folded state, the compression device can compress the cushioning pad to reduce the thickness of the cushioning pad, thereby reducing the thickness of the backrest, avoiding interference between the backrest and the seat cushion, so that the backrest is roughly parallel to the seat cushion in the folded state.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, cushioning pads are provided on both the backrest and the seat cushion. Correspondingly, there are two compression devices: one connected to the cushioning pad on the seat cushion to compress it and reduce the thickness of the seat cushion; the other connected to the cushioning pad on the backrest to compress it and reduce the thickness of the backrest. This arrangement can simultaneously reduce the thickness of both the seat cushion and the backrest, further preventing interference between the backrest and the seat cushion when rotating the backrest to the folded state, ensuring that the backrest is parallel to the horizontal plane in the folded state.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the compression device includes an air bag and an air pump, with the air pump connected to the air bag and a cushioning pad disposed inside the air bag. When compressing the cushioning pad, the air pump can draw air from the air bag, causing the air bag to contract and compress the cushioning pad under the action of external atmospheric pressure, thereby reducing the thickness of the cushioning pad. Using atmospheric pressure to compress the air bag and the cushioning pad ensures more even stress on the cushioning pad, preventing wrinkles from forming and interfering with the backrest.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the compression device further includes a first valve and a second valve, the air bag is provided with a first opening and a second opening, the air pump is connected to the first opening through the first valve, and the second valve is connected to the second opening.

[0016] When compressing the cushioning pad, the first valve is opened and the second valve is closed. At this time, air is drawn from the air bag by an air pump to reduce the thickness of the cushioning. During the compression of the cushioning pad and while the backrest is in the folded state, the first valve can be closed and the second valve opened; alternatively, both valves can be closed to maintain a smaller thickness for the air bag and cushioning. During the rotation of the backrest to the unfolded state and when the backrest is in the unfolded state, the first valve is closed and the second valve is opened. At this time, the air bag is connected to the outside atmosphere through the second valve. Outside air enters the air bag through the second valve, causing the air bag and cushioning pad to inflate. The cushioning pad can inflate automatically without inflating the air bag, simplifying control.

[0017] In some implementations, after the cushioning pad has fully inflated, the first valve closes while the second valve remains open. This prevents the airbag from being stressed when the occupant sits on it, thus extending its lifespan. Alternatively, after the cushioning pad has fully inflated, both the first and second valves remain closed, leaving some space inside the airbag. In this case, the airbag and cushioning pad can work together to support the occupant, further improving ride comfort.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the buffer pad includes a first sub-buffer pad and a second sub-buffer pad, the air bag includes a first sub-air bag and a second sub-air bag, the first sub-buffer pad is disposed inside the first sub-air bag, the second sub-buffer pad is disposed inside the second sub-air bag, and the air pump is connected to both the first sub-air bag and the second sub-air bag.

[0019] To ensure ride comfort, the cushioning pad generally has a certain shape. It is formed by splicing a first sub-cushion pad and a second sub-cushion pad. The first sub-cushion pad is compressed by the first sub-airbag, and the second sub-cushion pad is compressed by the second sub-airbag. This ensures that the entire cushioning pad is relatively flat after compression, and avoids the cushioning pad being too thick in some areas and interfering with the backrest.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the compression device may further include a compression motor, a reel, a pull rope, and a fixing plate. The compression motor is drivenly connected to the reel, which is rotatably disposed at the lower part of the buffer pad. The fixing plate covers the upper part of the buffer pad and is connected to the upper surface of the buffer pad. One end of the pull rope is connected to the fixing plate, and the other end of the pull rope is wound around the reel. When compressing the buffer pad, the compression motor drives the reel to rotate, causing the pull rope to gradually wind around the reel. At this time, the pull rope pulls the fixing plate, thereby compressing the buffer pad through the fixing plate to reduce the thickness of the buffer pad. When releasing the buffer pad, the compression motor drives the reel to rotate, causing the pull rope to gradually unwind from the reel. At this time, the pull rope elongates, and under the action of the elasticity of the buffer pad, the thickness of the buffer pad increases.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, the seating also includes a foam body, at least one of the backrest and seat cushion being provided with the foam body, and a cushioning pad being disposed on the foam body. The foam body allows for a smaller thickness of the cushioning pad, facilitating its compression.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the seating also includes a cover and an intermediate layer, with at least one of the backrest and seat cushion having a cover and an intermediate layer, the intermediate layer being located between the cushioning pad and the cover. The intermediate layer provides isolation between the cover and the airbag to prevent friction between them from causing noise; additionally, it also protects the airbag from leakage due to friction from the cover.

[0023] Secondly, embodiments of this application also provide a vehicle, including a vehicle body and a seat as described above, the seat being disposed on the vehicle body.

[0024] The vehicle provided in this application includes the seating in the above embodiments, and therefore can achieve substantially the same technical effects and solve substantially the same technical problems.

[0025] In conjunction with the second aspect, in some implementations of the second aspect, the vehicle body includes a floor with a first recessed portion, and a seat cushion is disposed within the first recessed portion; in the folded state, the surface of the backrest away from the seat cushion is on the same plane as the floor. With this configuration, in the folded state, the backrest is approximately parallel to the seat cushion, and the seat can be completely stored within the first recessed portion, further increasing the interior storage space.

[0026] In conjunction with the second aspect, in some implementations of the second aspect, the vehicle body includes a floor with a second recess provided on the floor, the seat cushion is hinged to the floor, and the seat can switch between a stowed state and a riding state; In the stowed state, the backrest is folded, and the seat cushion and backrest are flipped into the second recess; in the seated state, the backrest is unfolded, and the seat cushion is outside the second recess. In the stowed state, the backrest is folded, roughly parallel to the seat cushion, while the seat cushion and backrest are flipped into the second recess to further increase the storage space inside the vehicle.

[0027] Thirdly, embodiments of this application also provide a seating control method, including: receiving a first instruction to fold; controlling a compression device to compress a cushioning pad to reduce the thickness of the cushioning pad; wherein the cushioning pad is disposed on at least one of the backrest and the seat cushion of the seating, the backrest is erected at one end of the seat cushion, and the end of the backrest near the seat cushion is hinged to the seat cushion so that the backrest can switch between a folded state and an unfolded state, and in the folded state the backrest covers the seat cushion; the seating begins to fold.

[0028] The seating control method provided in this application, upon receiving a first instruction, controls a compression device to compress a cushioning pad to reduce its thickness. At least one of the backrest and seat cushion is provided with this cushioning pad; the compression device reduces the thickness of the cushioning pad, thereby reducing the thickness of at least one of the backrest and seat cushion. When the backrest rotates towards the seat cushion, because the thickness of at least one of the backrest and seat cushion is reduced, interference between the backrest and seat cushion can be avoided, allowing the backrest to be approximately parallel to the seat cushion in the folded state. The backrest will not tilt relative to the seat cushion, improving the decorative effect of the seating in the folded state. Furthermore, because the backrest is approximately parallel to the seat cushion in the folded state, the space occupied by the seating in the folded state can also be reduced, increasing the vehicle's storage space.

[0029] In conjunction with the third aspect, in some implementations of the third aspect, the seating may include a controller connected to both the compression device and the adjustment device, and correspondingly, the first instruction may be an instruction sent to the controller. Of course, in other embodiments, the controller may also be a vehicle controller, for example, the controller may include an on-board computer (electronic control unit, ECU).

[0030] In conjunction with the third aspect, in some implementations of the third aspect, where the seating includes an adjustment device, when adjusting the angle between the backrest and the seat cushion using the adjustment device, if the angle between the backrest and the seat cushion reaches a first preset angle, the adjustment device can trigger a first command and send the first command to the controller. Alternatively, the user can input a folding command to the controller (e.g., via a button or voice control) to drive the adjustment device to fold the backrest. Correspondingly, the folding command input by the user to the controller can be the first command. In the implementation where the user manually rotates the backrest, the first command can be triggered when the angle between the backrest and the seat cushion reaches a second preset angle; for example, by detecting the rotation angle of the backrest using an angle detection device (angle sensor), and sending the first command to the controller when the rotation angle reaches the second preset angle; alternatively, a limit switch can be installed on the seating, triggering the limit switch when the backrest rotates to the second preset angle to send the first command to the controller.

[0031] The first preset angle and the second preset angle are both smaller than the angle between the backrest and the seat cushion when the backrest is unfolded, so as to avoid triggering the first command when the occupant adjusts the backrest angle for seating comfort.

[0032] In conjunction with the third aspect, in some implementations of the third aspect, the folding action can be a rotation of the backrest towards the seat cushion, so that the backrest rotates to a folded state covering the seat cushion. For example, the user can manually drive the backrest to fold. Alternatively, in implementations where the seating includes an adjustment device, the folding action of the backrest can be driven by the adjustment device.

[0033] In conjunction with the third aspect, in some implementations of the third aspect, the compression device is controlled to compress the cushioning pad to reduce its thickness; the folding action of the seat includes: controlling the compression device to compress the cushioning pad, and after compression stops, the seat begins to fold. This configuration allows the compression device to fully compress the cushioning pad before the backrest contacts it, thus avoiding interference with the backrest's rotation.

[0034] In conjunction with the third aspect, in some implementations of the third aspect, the compression device is controlled to compress the cushioning pad to reduce its thickness; the folding action of the seat begins by controlling the compression device to compress the cushioning pad, and the seat begins to fold before the compression stops. With this configuration, when the backrest rotates to contact the seat cushion, the compression device is compressing the cushioning pad, and the backrest and the compression device jointly compress the cushioning pad; the backrest can provide assistance to the compression device in compressing the cushioning pad.

[0035] In conjunction with the third aspect, in some implementations of the third aspect, the method further includes: receiving a second instruction to unfold; the seat initiating the unfolding action; and controlling the compression device to release the cushioning pad to increase the thickness of the cushioning pad.

[0036] In a compression device comprising an air bag and an air pump, releasing the cushioning pad can stop the air pump and allow outside air to enter the air bag. At this point, the cushioning pad's own elasticity allows outside air to enter the air bag, increasing its thickness. Alternatively, the air bag can be inflated by the air pump supplying air through a delivery port, further increasing the cushioning pad's thickness due to its own elasticity.

[0037] In conjunction with the third aspect, in some implementations of the third aspect, the seat begins its unfolding action; controlling the compression device to release the cushioning pad to increase its thickness includes: after the seat has completed its unfolding action, controlling the compression device to release the cushioning pad. This arrangement avoids contact between the backrest and the seat cushion, thus preventing the cushioning pad from releasing.

[0038] In conjunction with the third aspect, in some implementations of the third aspect, the process of controlling the compression device to release the cushioning pad to increase its thickness includes: controlling the compression device to release the cushioning pad before the seat completes the unfolding action. This configuration allows the unfolding and releasing actions to occur simultaneously, thus shortening the seat's operating time.

[0039] Fourthly, embodiments of this application also provide a control device, including a processor and a memory coupled together. The memory stores program instructions, and when the program instructions stored in the memory are executed by the processor, the method described above is implemented.

For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0053] The use of prefixes such as "first" and "second" in this application embodiment is solely for distinguishing different descriptive objects and does not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes to distinguish descriptive objects in this application embodiment does not constitute a limitation on the described objects. The description of the described objects is found in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.

[0054] In the embodiments of this application, the term "connection" or "linking" should be interpreted broadly. For example, "connection" can be a fixed connection, an electrical connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0055] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0056] Please refer to Figure 1 This application provides a vehicle, which may include a body 10, a suspension system, and a power system. The suspension system includes wheels and a chassis structure. The chassis structure is connected to both the wheels and the body 10, and the chassis structure and wheels support the body 10 on the ground. The number of wheels may include 4, 6, etc., and this application does not limit this. Taking 4 wheels as an example, the 4 wheels include two front wheels and two rear wheels. The two front wheels are located on the same axis, and the two rear wheels are located on another axis. The two axes are along the length direction of the vehicle. Figure 1 The Y-direction (in the vehicle's driving direction) is set parallel and spaced. It can be understood that the vehicle's length direction can be parallel to the vehicle's driving direction, while the vehicle's width direction (e.g., the Y-direction) is parallel and spaced. Figure 1 The X direction (in the equation) is perpendicular to the vehicle's direction of travel and parallel to the horizontal plane.

[0057] In the above implementation, the power system is mounted on the vehicle body 10 and is connected to the wheels to drive the wheels to rotate, thereby providing power for vehicle movement. Taking a vehicle with four wheels as an example, the power system can be connected to the two front wheels (front-wheel drive vehicle), or the power system can be connected to the two rear wheels (rear-wheel drive vehicle), or the power system can be connected to both the front and rear wheels (four-wheel drive vehicle). This application embodiment does not impose any limitations on this.

[0058] In some embodiments, the vehicle may include a gasoline-powered vehicle, and accordingly, the powertrain may include an engine and a transmission, the transmission being driveably connected to both the engine and the wheels, the transmission being able to transmit power from the engine to the wheels to drive the wheels to rotate, thereby providing power for the vehicle to move.

[0059] In other embodiments, the vehicle may include an electric vehicle, and correspondingly, the power system may include a battery and a motor. The motor may be connected to the wheel drive via a reducer, or it may be directly connected to the wheel drive. The battery is used to supply power to the motor so that the motor can drive the wheel to rotate, thereby providing power for the vehicle to move.

[0060] In other embodiments, the vehicle may also include a hybrid electric vehicle (e.g., a hybrid electric vehicle (HEV)). In some examples, the hybrid electric vehicle may include a series hybrid electric vehicle (SHEV). Accordingly, the power system may include an engine, a generator, a battery, and an electric motor. The engine drives the generator to generate electricity, which is then delivered to the battery or the electric motor, which drives the wheels to rotate.

[0061] In other examples, hybrid vehicles may include parallel hybrid electric vehicles (PHEVs), in which the powertrain may include an engine, a generator, a battery, and an electric motor. The engine and the electric motor work together to drive the wheels, while the engine and the electric motor are two separate systems that can drive the wheels independently. They can drive together or independently on different road surfaces.

[0062] In other examples, hybrid vehicles may include PSHEVs (Powertrain Hybrid Electric Vehicles), whose powertrain includes an engine, a battery, and an electric motor. In an engine-dominant configuration, the engine serves as the primary power source, while the electric motor serves as the auxiliary power source, both driving the wheels. In an electric motor-dominant configuration, the engine serves as the auxiliary power source, while the electric motor serves as the primary power source, both driving the wheels.

[0063] Continue to refer to Figure 1 In this embodiment, the vehicle body 10 forms a driver's cab and a passenger cabin, with the driver's cab located at the front of the passenger cabin. The driver's cab is equipped with front seats 101, including a driver's seat and a front passenger seat. An instrument panel is located at the front of the driver's cab, which can display devices such as a speedometer, odometer, and navigation screen. The passenger cabin contains multiple passenger seats. When in the vehicle, the driver sits in the driver's seat to drive, the front passenger sits in the front passenger seat, and other passengers sit in the passenger cabin seats.

[0064] Please refer to Figure 2 and combined Figure 1 This application provides a seating arrangement 20, which may include a front seat 101 and / or a rear seat 102 in a vehicle. This application does not limit the scope of the seating arrangement. The following description will use the rear seat 102 as an example.

[0065] The seating 20 in this embodiment includes a seat cushion 210 and a backrest 220. The seat cushion 210 is disposed at the lower end of the backrest 220 and is generally parallel to the horizontal plane. The backrest 220 is erected at one end of the seat cushion 210 along the direction parallel to the horizontal plane. For example, the backrest 220 can be erected at one end of the seat cushion 210 along the length direction of the vehicle, such as at the rear end of the seat cushion 210 along the length direction of the vehicle. The backrest 220 and the seat cushion 210 are hinged. For example, the hinge axis L1 of the backrest 220 can be generally parallel to the horizontal plane and parallel to the width direction of the vehicle, so that the backrest 220 can switch between a folded state and an unfolded state. Figure 3 As shown, in the folded state, the backrest 220 rotates around the hinge axis L1, and the backrest 220 covers the seat cushion 210 to reduce the space occupied by the seat 20 and increase the storage space inside the vehicle; as Figure 2 As shown, in the unfolded state, the backrest 220 rotates around the hinge axis L1 to a position tilted relative to the seat cushion 210 for seating.

[0066] It is understood that the backrest 220 and the seat cushion 210 can also be connected via an adjustment device. This device can adjust the rotation angle of the backrest 220 around the hinge axis L1 to adjust the tilt of the backrest 220 relative to the seat cushion 210, thereby improving seating comfort. For example, the adjustment device may include a motor, a drive gear, and a driven gear. The drive gear is driven by the motor's main shaft, and the driven gear is driven by the backrest 220; the drive gear and driven gear mesh. When adjusting the backrest 220, the motor drives the drive gear to rotate, which in turn drives the backrest 220 to rotate via the driven gear.

[0067] In some examples, the backrest 220 can be switched between an unfolded and folded state by rotating it through an adjusting device. In other examples, the backrest 220 can be switched between the unfolded and folded states by manually pushing it. When switching between the unfolded and folded states, the adjusting device can be disengaged from the backrest 220, for example, by disengaging the driving gear from the driven gear, or by disengaging the driven gear from the backrest 220.

[0068] This application embodiment does not limit the adjustment device, as long as the tilt of the backrest 220 relative to the seat cushion 210 can be adjusted by the adjustment device.

[0069] like Figure 4As shown, in the related technology, both the seat cushion 210 and the backrest 220 have a certain thickness. When the backrest 220 rotates towards the seat cushion 210 to a position where it is about to be folded, the surface of the backrest 220 facing the seat cushion 210 contacts the upper surface of the seat cushion 210, which causes interference between the backrest 220 and the seat cushion 210, preventing the backrest 220 from continuing to rotate. This results in the backrest 220 being tilted relative to the seat cushion 210 in the folded state. In other words, the backrest 220 is tilted relative to the horizontal plane in the folded state, which affects the decorative effect of the seat 20 in the folded state, and the seat 20 occupies a large space in the folded state.

[0070] Please refer to Figure 5 The seating 20 provided in this embodiment further includes a cushioning pad 240 and a compression device 250. At least one of the backrest 220 and the seat cushion 210 is provided with the cushioning pad 240. The compression device 250 is connected to the cushioning pad 240 and is used to reduce the thickness of the cushioning pad 240. The compression device 250 can reduce the thickness of the cushioning pad 240, thereby reducing the thickness of at least one of the backrest 220 and the seat cushion 210. When the backrest 220 rotates towards the seat cushion 210, because the thickness of at least one of the backrest 220 and the seat cushion 210 is reduced, interference between the backrest 220 and the seat cushion 210 can be avoided. This allows the backrest 220 to be approximately parallel to the seat cushion 210 in the folded state, and the backrest 220 will not tilt relative to the seat cushion 210, improving the decorative effect of the seating 20 in the folded state. On the other hand, since the backrest 220 is approximately parallel to the seat cushion 210 in the folded state, the space occupied by the seating 20 in the folded state can also be reduced, increasing the vehicle's storage space.

[0071] Continue to refer to Figure 5 In some embodiments, a cushioning pad 240 can be disposed on a seat cushion 210, which includes a first support 211. The first support 211 serves as the base of the seat cushion 210. Correspondingly, the cushioning pad 240 can be disposed on the upper part of the first support 211. In the folded state, the cushioning pad 240 is located between the first support 211 and the backrest 220. The cushioning pad 240 may include at least one of sponge, polyurethane foam, and latex. The cushioning pad 240 has good flexibility and resilience. When riding, the occupant can sit on the cushioning pad 240 to improve riding comfort.

[0072] In the above implementation, before or during the rotation of the backrest 220 from the unfolded state to the folded state, the compression device 250 can compress the cushion 240 to reduce the thickness of the cushion 240, thereby reducing the thickness of the seat cushion 210, avoiding interference between the backrest 220 and the seat cushion 210, so that in the folded state, the backrest 220 is approximately parallel to the seat cushion 210.

[0073] In the example where the compression device 250 compresses the cushioning pad 240 during the rotation of the backrest 220 from the unfolded state to the folded state, the compression device 250 can compress the cushioning pad 240 before the backrest 220 comes into contact with it, thus avoiding affecting the rotation of the backrest 220. Alternatively, the compression device 250 can compress the cushioning pad 240 while the backrest 220 is in contact with it, in which case the backrest 220 and the compression device 250 jointly compress the cushioning pad 240, and the backrest 220 can assist the compression device 250 in compressing the cushioning pad 240.

[0074] Continue to refer to Figure 5 In this embodiment, the seat 20 may further include a foam body 260, which is disposed on the first support 211 and may be located between the cushioning pad 240 and the first support 211. The foam body 260 increases the thickness of the seat cushion 210, ensuring seating comfort. On the other hand, the foam body 260 allows for a smaller thickness of the cushioning pad 240, facilitating its compression.

[0075] For example, the foam body 260 is an elastomer manufactured by a foaming process. For example, the material of the foam body 260 may include sponge, polyurethane foam, etc. The stiffness of the foam body 260 can be greater than that of the cushioning pad 240. In other words, the cushioning pad 240 is softer than the foam body 260. Since the cushioning pad 240 is closer to the occupant, it can improve the comfort of riding.

[0076] Please refer to Figure 5 and Figure 6 In this embodiment, the seating 20 further includes a cover 230, which is located on the side of the cushioning pad 240 opposite to the foam body 260 and is used for contact with the occupant. Exemplarily, the material of the cover 230 may include leather, fabric, etc., and this embodiment does not limit this. The cover 230 can wrap around the foam body 260 and the cushioning pad 240, providing protection for them and improving the decorative effect of the seating.

[0077] Continue to refer to Figure 5 and Figure 6This application does not limit the compression device 250, as long as it can compress the buffer pad 240. In some examples, the compression device 250 may include an air bag 251 and an air pump 252. The air bag 251 is a sealed bag and may have a certain degree of elasticity. The buffer pad 240 is disposed inside the air bag 251, and the air pump 252 is connected to the air bag 251. When compressing the buffer pad 240, the air pump 252 can draw air out of the air bag 251, so that under the action of external atmospheric pressure, the air bag 251 contracts and compresses the buffer pad 240, thereby reducing the thickness of the buffer pad 240.

[0078] It is understandable that since the cushioning pad 240 is generally sheet-shaped, in other words, the thickness of the cushioning pad 240 is less than the length and width of the cushioning pad 240. Thus, under the action of atmospheric pressure, both the cushioning pad 240 and the air bag 251 will shrink along the thickness direction to reduce the thickness of the cushioning pad 240.

[0079] In this embodiment, the air pump 252 draws air from the air bag 251 and compresses the air bag 251 and the cushioning pad 240 by atmospheric pressure, so that the cushioning pad 240 is subjected to more uniform force, so as to avoid wrinkles in the cushioning pad 240 and prevent the wrinkles from interfering with the backrest 220.

[0080] In the above implementation, when the backrest 220 is rotated to the unfolded state or when the backrest 220 is in the unfolded state, air can be supplied to the air bag 251 by the air pump 252 so that the cushioning pad 240 rebounds, increases the thickness of the cushioning pad 240, and thus improves the comfort of the seat 20.

[0081] In some implementations, when the backrest 220 is in the unfolded state, air can be supplied to the air bag 251 by the air pump 252 to inflate the air bag 251. At this time, the air bag 251 and the cushioning pad 240 can jointly support the occupant. For example, when traveling on bumpy roads, the air bag 251 and the cushioning pad 240 can jointly support the occupant, which can further improve the comfort of the seat 20.

[0082] Please refer to Figure 7 In some examples, the compression device 250 also includes a first valve 253 and a second valve 254. The air bag 251 is provided with a first opening and a second opening. The air pump 252 is connected to the first opening through the first valve 253, and the second valve 254 is connected to the second opening. In other words, the second opening can be connected to the outside through the second valve 254. When the seat 20 is in normal use (when it can be sat on), the first valve 253 can be closed and the second valve 254 can be opened. When compressing the cushion 240, the first valve 253 is opened and the second valve 254 is closed. At this time, the air pump 252 draws air out of the air bag 251 to reduce the thickness of the cushion 240 (e.g., ...). Figure 8(As shown); during the compression of the cushioning pad 240 and the folding of the backrest 220, the first valve 253 can be closed and the second valve 254 opened; or, the first valve 253 and the second valve 254 can be closed to keep the air bag 251 and the cushioning at a small thickness. During the rotation of the backrest 220 to the unfolded state and when the backrest 220 is in the unfolded state, the first valve 253 is closed and the second valve 254 is opened. At this time, the air bag 251 is connected to the outside atmosphere through the second valve 254. Outside air enters the air bag 251 through the second valve 254, and the air bag 251 and the cushioning pad 240 inflate. The cushioning pad 240 can inflate automatically without inflating the air bag 251, which simplifies the control process.

[0083] In some implementations, after the cushioning pad 240 has fully inflated, the first valve 253 closes while the second valve 254 remains open. This prevents the airbag 251 from being stressed when the occupant sits on it, thus extending its lifespan. Alternatively, after the cushioning pad 240 has fully inflated, both the first and second valves 253 and 254 remain closed. In this case, some space remains inside the airbag 251, allowing the airbag 251 and the cushioning pad 240 to work together to support the occupant, further improving ride comfort.

[0084] Continue to refer to Figure 7 In the above implementation, the compression device 250 further includes a first air guide pipe 255 and a second air guide pipe 256. One end of the first air guide pipe 255 is connected to the air pump 252, and the other end is connected to a first opening. A first valve 253 can be installed on the first air guide pipe 255 to control its opening and closing. One end of the second air guide pipe 256 is connected to a second opening, and the other end is connected to the outside. A second valve 254 is installed on the second air guide pipe 256 to control its opening and closing. With this configuration, the air pump 252 can be placed outside the seat cushion 210 to avoid occupying space in the seat cushion 210.

[0085] In some examples, the air pump 252 can be an existing air pump 252 in the vehicle. In other words, the air pump 252 used to compress the cushioning pad 240 can be shared with other air pumps 252 in the vehicle to reduce the structural complexity of the vehicle and improve the utilization rate of parts. Exemplarily, the seat 20 may also include a lumbar support disposed on the backrest 220, which can support the occupant's lower back to improve seating comfort. This lumbar support can be an inflatable lumbar support; that is, the size of the lumbar support can be adjusted by inflating it with an air pump. In this embodiment, the air pump 252 used to compress the cushioning pad 240 can share the same air pump as the air pump used to inflate the lumbar support. Of course, the air pump 252 can also be other air pumps in the vehicle; this embodiment does not limit this.

[0086] In other examples, the air pump 252 may also be an air pump that is separately connected to the air bag 251.

[0087] In some embodiments, the cushioning pad 240 includes a first sub-cushioning pad and a second sub-cushioning pad, which may be arranged generally in a direction parallel to the horizontal plane and may be located generally in the same plane parallel to the horizontal plane. Correspondingly, the air bag 251 includes a first sub-air bag and a second sub-air bag, with the first sub-cushioning pad disposed within the first sub-air bag and the second sub-cushioning pad disposed within the second sub-air bag. The air pump 252 is in communication with both the first and second sub-air bags.

[0088] To ensure ride comfort, the cushioning pad 240 generally has a certain shape. It is formed by splicing the first sub-cushion pad and the second sub-cushion pad. The first sub-cushion pad is compressed by the first sub-airbag, and the second sub-cushion pad is compressed by the second sub-airbag. This ensures that the entire cushioning pad 240 is relatively flat after compression, and avoids the cushioning pad 240 being too thick in some areas and interfering with the backrest 220.

[0089] It is understood that the buffer pad 240 in this embodiment may also include other sub-buffer pads. In other words, the number of sub-buffer pads may be greater than or equal to three. Correspondingly, each sub-buffer pad is set in a sub-air bag, and each sub-air bag is connected to the air pump 252. The air pump 252 can extract air from each sub-air bag to compress each sub-buffer pad.

[0090] Please refer to Figure 9 and combined Figure 5 In some embodiments, the seat 20 further includes an intermediate layer 270 disposed between the cover 230 and the cushioning pad 240. In the implementation where the compression device 250 includes an air bag 251, the intermediate layer 270 may be disposed between the air bag 251 and the cover 230. The intermediate layer 270 can isolate the cover 230 and the air bag 251 to avoid friction between them and the air bag 251, thus preventing abnormal noise. In addition, it can also protect the air bag 251 to prevent it from leaking due to friction from the cover 230.

[0091] For example, the material of the intermediate layer 270 may include fabric and / or felt, etc., and the material of the intermediate layer 270 is not limited in this embodiment. The intermediate layer 270 can be connected to the face cover 230 or the air bag 251. In the implementation of the intermediate layer 270 being connected to the face cover 230, the intermediate layer 270 can be connected to the face cover 230 by adhesive, or the intermediate layer 270 can be connected to the face cover 230 by sewing; in the implementation of the intermediate layer 270 being connected to the air bag 251, the intermediate layer 270 can be connected to the air bag 251 by adhesive.

[0092] In other embodiments, the compression device 250 may further include a compression motor, a reel, a pull rope, and a fixing plate. The compression motor is drivenly connected to the reel, which is rotatably disposed at the lower part of the buffer pad 240. The fixing plate covers the upper part of the buffer pad 240 and is connected to the upper surface of the buffer pad 240. One end of the pull rope is connected to the fixing plate, and the other end of the pull rope is wound around the reel. When compressing the buffer pad 240, the compression motor drives the reel to rotate, which allows the pull rope to gradually wind around the reel. At this time, the pull rope pulls the fixing plate, thereby compressing the buffer pad 240 through the fixing plate to reduce the thickness of the buffer pad 240. When releasing the buffer pad 240, the compression motor drives the reel to rotate, which allows the pull rope to gradually unwind from the reel. At this time, the pull rope elongates, and under the elasticity of the buffer pad 240, the thickness of the buffer pad 240 increases.

[0093] In the above implementation, there can be multiple pull ropes, one end of which is connected to a fixed plate. Correspondingly, multiple reels and multiple compression motors can be set, with each compression motor connected to a reel for transmission, and each pull rope wound on a reel. During compression, each reel can be rotated so that the pull rope is wound on the corresponding reel, and each pull rope pulls the fixed plate simultaneously to reduce the thickness of the buffer pad 240. When releasing the buffer pad 240, each reel rotates so that the pull rope on each reel gradually unwinds, each pull rope elongates, and the thickness of the buffer pad 240 increases.

[0094] The multiple pull ropes are evenly distributed on the fixing plate to ensure that the fixing plate is evenly stressed and that the buffer pad 240 is relatively flat after being compressed.

[0095] It is understood that the embodiments of this application do not limit the compression device 250, as long as the compression device 250 can compress the buffer pad 240 to reduce the thickness of the buffer pad 240.

[0096] Please refer to Figure 10 In some embodiments, a cushioning pad 240 may be disposed on a backrest 220, which includes a second support 261 hinged to a seat cushion 210. In an implementation where the seat cushion 210 includes a first support 211, the second support 261 is hinged to the first support 211, allowing the backrest 220 to rotate relative to the seat cushion 210 and switch between an unfolded and folded state. The cushioning pad 240 is disposed on the second support 261, and when the backrest 220 is in the folded state, the cushioning pad 240 is located between the second support 261 and the seat cushion 210. The material and structure of the cushioning pad 240 disposed on the backrest 220 may be the same as those of the cushioning pad 240 disposed on the seat cushion 210 (e.g., Figure 5Similar to (as shown), the cushioning pad 240 has good flexibility and resilience; when riding, passengers can lean on the cushioning pad 240 to improve riding comfort.

[0097] In the above implementation, before or during the rotation of the backrest 220 from the unfolded state to the folded state, the compression device 250 can compress the cushion 240 to reduce the thickness of the cushion 240, thereby reducing the thickness of the backrest 220, avoiding interference between the backrest 220 and the seat cushion 210, so that in the folded state, the backrest 220 is approximately parallel to the seat cushion 210.

[0098] In the example where the compression device 250 compresses the cushioning pad 240 during the rotation of the backrest 220 from the unfolded state to the folded state, the compression device 250 can compress the cushioning pad 240 before the backrest 220 comes into contact with it, thus avoiding affecting the rotation of the backrest 220. Alternatively, the compression device 250 can compress the cushioning pad 240 simultaneously with the backrest 220 coming into contact with it. In this case, the backrest 220 and the compression device 250 jointly compress the cushioning pad 240, and the backrest 220 can assist the compression device 250 in compressing the cushioning pad 240.

[0099] In this embodiment, the backrest 220 may further include a foam body 260, which is disposed on the second support 261 and may be located between the cushioning pad 240 and the second support 261. The foam body 260 increases the thickness of the backrest 220, ensuring seating comfort. Furthermore, the foam body 260 allows for a smaller thickness of the cushioning pad 240, facilitating its compression.

[0100] The material of the foam body 260 set on the second support 261 can be roughly the same as that of the foam body 260 set on the seat cushion 210, and will not be described in detail here.

[0101] In this embodiment, the backrest 220 further includes a cover 230, which is located on the side of the cushioning pad 240 away from the foam body 260 and is used to contact the occupant. The cover 230 can wrap around the foam body 260 and the cushioning pad 240, thus protecting them and improving the decorative effect of the seat.

[0102] This application embodiment does not limit the compression device 250, as long as it can compress the cushioning pad 240. It is understood that the compression device 250 used to compress the cushioning pad 240 on the backrest 220 can be the same as the compression device 250 used to compress the cushioning on the seat cushion 210 (e.g., Figure 7 The results are roughly the same as those shown, so I will not repeat them here.

[0103] Please refer to Figure 11 In some embodiments, both the backrest 220 and the seat cushion 210 are provided with cushioning pads 240. Correspondingly, there are two compression devices 250. One compression device 250 is connected to the cushioning pad 240 on the seat cushion 210 to compress the cushioning pad 240 on the seat cushion 210, thereby reducing the thickness of the seat cushion 210. The other compression device 250 is connected to the cushioning pad 240 on the backrest 220 to compress the cushioning pad 240 on the backrest 220, thereby reducing the thickness of the backrest 220. This arrangement can reduce the thickness of both the seat cushion 210 and the backrest 220 simultaneously, further avoiding interference between the backrest 220 and the seat cushion 210 when the backrest 220 is rotated to the folded state, ensuring that the backrest 220 is parallel to the horizontal plane in the folded state.

[0104] Please refer to Figure 12 In this embodiment of the application, the vehicle body 10 also includes a floor 110, on which a first recess 111 is provided, and a seat cushion 210 is disposed within the first recess 111. The first support 211 (e.g. Figure 5 (As shown) The seat 20 can be fixed to the floor 110 by means of bolts or welding. Please refer to... Figure 13 In the folded state, the backrest 220 covers the seat cushion 210, and the backrest 220 is away from the surface of the seat cushion 210. Figure 13 The upper surface of the seat 220 is roughly in the same plane as the floor 110. With this arrangement, in the folded state, the backrest 220 is roughly parallel to the seat cushion 210, and the seat 20 can be completely stored in the first recess 111 to further increase the interior storage space.

[0105] Please refer to Figure 14 In other embodiments, a second recess 112 is provided on the floor 110, and the seat cushion 210 is hinged to the floor 110 outside the second recess 112. For example, the first bracket 211 is hinged to the floor 110, and the hinge axis L2 between the seat cushion 210 and the floor 110 can be parallel to the width direction of the vehicle, so that the seat 20 can switch between a stowed state and a seated state. In the seated state (e.g. Figure 14 As shown), the backrest 220 is in the unfolded state, and the seat cushion 210 is located outside the second recess 112 for occupants to sit on. In the stowed state (as shown...), Figure 15 As shown), the backrest 220 is in a folded state. While the backrest 220 is roughly parallel to the seat cushion 210, the seat cushion 210 and the backrest 220 are flipped into the second recess 112 to further increase the storage space inside the vehicle.

[0106] This application embodiment also provides a seating control method, which can be used for the seating 20 in the above embodiments. The seating control method includes: S102: Receive the first instruction to fold.

[0107] In some embodiments, the seating 20 (such as...) Figure 5 (As shown) may include a controller connected to both the compression device 250 and the regulating device, and correspondingly, the first instruction may be an instruction sent to the controller. Of course, in other embodiments, the controller may also be the vehicle controller, for example, the controller may include an on-board computer (electronic control unit, ECU).

[0108] It is understandable that in the implementation of the seat 20 including the adjustment device, when adjusting the angle between the backrest 220 and the seat cushion 210, if the angle between the backrest 220 and the seat cushion 210 reaches a first preset angle, the adjustment device can trigger a first command and send the first command to the controller. Of course, the user can also input a folding command to the controller (e.g., inputting a folding command via a button or voice control) to drive the adjustment device to fold the backrest 220. Correspondingly, the folding command input by the user to the controller can be the first command. In the implementation where the user manually rotates the backrest 220, the first command can be triggered when the backrest 220 rotates to a second preset angle with the seat cushion 210; for example, by detecting the rotation angle of the backrest 220 through an angle detection device (angle sensor), the first command is sent to the controller when the rotation angle reaches the second preset angle; alternatively, a limit switch can be set on the seat 20, and when the backrest 220 rotates to the second preset angle, the backrest 220 triggers the limit switch to send the first command to the controller.

[0109] The first preset angle and the second preset angle are both smaller than the angle between the backrest 220 and the seat cushion 210 when the backrest 220 is unfolded, so as to avoid the occupant triggering the first command when adjusting the angle of the backrest 220 for seating comfort.

[0110] The seating control method provided in this application embodiment further includes, after receiving the first instruction: S104: Control the compression device to compress the buffer pad to reduce the thickness of the buffer pad.

[0111] Continue to refer to Figure 5 For example, after receiving the first instruction, the controller controls the compression device 250 to compress the buffer pad 240; for example, in an implementation where the compression device 250 includes an air bag 251 and an air pump 252, the controller controls the air pump 252 to extract air from the air bag 251 to compress the buffer pad 240, thereby reducing the thickness of the buffer pad 240.

[0112] The seating control method provided in this application also includes: S106: The seat begins to fold.

[0113] Understandably, the folding motion can be applied to the backrest at 220 degrees (e.g.) Figure 5 The action of rotating the backrest 220 towards the seat cushion 210 causes the backrest 220 to rotate to a folded state covering the seat cushion 210. For example, the user can manually drive the backrest 220 to fold. Alternatively, in an implementation where the seat 20 includes an adjustment device, the folding action of the backrest 220 can be driven by the adjustment device.

[0114] The seating control method provided in this application embodiment controls the compression device 250 (e.g., after receiving a first instruction) Figure 5 (As shown) The compression device 250 compresses the cushioning pad 240 to reduce its thickness. At least one of the backrest 220 and the seat cushion 210 is provided with the cushioning pad 240. The compression device 250 reduces the thickness of the cushioning pad 240, thereby reducing the thickness of at least one of the backrest 220 and the seat cushion 210. When the backrest 220 rotates towards the seat cushion 210, because the thickness of at least one of the backrest 220 and the seat cushion 210 is reduced, interference between the backrest 220 and the seat cushion 210 can be avoided. This allows the backrest 220 to be approximately parallel to the seat cushion 210 in the folded state, preventing the backrest 220 from tilting relative to the seat cushion 210 and improving the decorative effect of the seat 20 in the folded state. On the other hand, since the backrest 220 is approximately parallel to the seat cushion 210 in the folded state, the space occupied by the seat 20 in the folded state can also be reduced, increasing the vehicle's storage space.

[0115] In some embodiments, the controller controls the compression device 250 (e.g. Figure 5 As shown, after the compression of the cushioning pad 240 stops, that is, after the cushioning pad 240 is fully compressed, the seat 20 begins to fold. This arrangement ensures that the compression device 250 compresses the cushioning pad 240 before the backrest 220 comes into contact with it, thus avoiding affecting the rotation of the backrest 220.

[0116] In other embodiments, the controller controls the compression device 250 (e.g. Figure 5 As shown, the cushioning pad 240 is compressed, and before the compression stops, the seat 20 begins to fold. With this configuration, when the backrest 220 rotates to contact the seat cushion 210, the compression device 250 is compressing the cushioning pad 240. The backrest 220 and the compression device 250 jointly compress the cushioning pad 240, and the backrest 220 can provide assistance to the compression device 250 in compressing the cushioning pad 240.

[0117] In some embodiments, the seating control method provided in this application further includes: receiving a second instruction to unfold; and the seating 20 starting to unfold.

[0118] For example, in an implementation where the seat 20 includes an adjustment device, after receiving a second command, the controller controls the adjustment device to drive the backrest 220 to rotate away from the seat cushion 210, i.e., the seat 20 begins to unfold. Accordingly, the second command can be triggered by the occupant via a button or voice control.

[0119] Please refer to Figure 5 After receiving the second instruction, the controller controls the compression device 250 to release the buffer pad 240, thereby increasing the thickness of the buffer pad 240. For example, in an implementation where the compression device 250 includes an air bag 251 and an air pump 252, releasing the buffer pad 240 can stop the air pump 252 from operating and allow outside air to enter the air bag 251. At this time, due to the elasticity of the buffer pad 240 itself, outside air enters the air bag 251, increasing the thickness of the buffer pad 240. Alternatively, the air pump 252 can supply air into the air bag 251 through a delivery hole, causing the air bag 251 to expand, and the thickness of the buffer pad 240 increases due to its own elasticity.

[0120] In some embodiments, after the seat 20 has completed its unfolding action, in other words, after the backrest 220 has rotated to stand upright on the seat cushion 210, the controller controls the compression device 250 to release the cushioning pad 240. This arrangement prevents the backrest 220 from contacting the seat cushion 210, thus preventing the cushioning pad 240 from being released.

[0121] In other embodiments, the compression device 250 releases the cushioning pad 240 before the seat 20 completes its unfolding action. This configuration allows the unfolding and releasing actions to occur simultaneously, thus shortening the operation time of the seat 20.

[0122] In some examples, when the backrest 220 rotates to separate from the seat cushion 210, the compression device 250 can be controlled to release the cushion 240, thereby shortening the action time of the seat 20 without preventing the cushion 240 from being released due to contact between the backrest 220 and the seat cushion 210.

[0123] In other examples, the compression device 250 is controlled to release the cushion 240 before the backrest 220 rotates to separate from the seat cushion 210. At this time, the thickness of the cushion 240 increases, and under the cushioning, it can provide some assistance for the unfolding of the backrest 220, further reducing the action time of the seat cushion 210 and the seat 20.

[0124] Figure 16This is a schematic diagram of a control device provided in an embodiment of this application. This application also provides a control device 800, which includes a memory 810, a processor 820, and a communication interface 830.
