Description

Seat assembly, seat and control method thereof, control device, and vehicle Technical Field

[0001] The present application relates to the field of mechanical and electronic technology, and in particular to a seat assembly, a seat and a control method thereof, a control device, and a vehicle. Background Art

[0002] Transportation is an indispensable part of modern people's life. With the changes of the times and the advancement of science and technology, there are more and more transportation tools around people, which has brought great convenience to everyone's life.

[0003] Common modes of transportation include cars, airplanes, and ships. Taking cars as an example, different vehicles have varying numbers of seats, depending on the number of people they can carry. For example, a family sedan has a driver's seat, a front passenger seat, and several rear seats.

[0004] With the development of the automotive industry, while car seats meet the requirements of safety and functionality, passengers have put forward higher requirements for riding comfort, and expect to have a larger space for activities and a wider field of vision. For example, if the backrest of the front seat is folded down onto the seat cushion, the passenger's activity space can be increased, the field of vision can be eliminated, and the riding experience and comfort of the rear passengers can be effectively improved. However, in order to better support the human back, the backrest is usually not flat. For example, a protruding lumbar support is provided near the waist of the human body, and bucket seats are also provided with side wings on both sides of the backrest. As a result, even if the backrest is folded down on the seat cushion, the overall height of the seat is still relatively large and occupies a large space.

[0005] Summary of the Invention

[0006] The present application provides a seat assembly, a seat and a control method thereof, a control device, and a vehicle, which can overcome the problems in the related art. The technical solution is as follows:

[0007] In a first aspect, a seat assembly is provided, which includes a base, a seat cushion bracket, a backrest bracket and a connecting rod. The backrest bracket is rotatably connected to the base so that the backrest bracket can adjust its angle relative to the base. The seat cushion bracket has a front edge and a rear edge relative to each other, wherein the rear edge is close to the backrest bracket. The seat cushion bracket is movably connected to the base, and the seat cushion bracket can move relative to the base in a direction close to or away from the backrest bracket. The first connection between the seat cushion bracket and the base is close to the rear edge. One end of the connecting rod is rotatably connected to the seat cushion bracket, and the second connection between the connecting rod and the seat cushion bracket is close to the front edge. The other end of the connecting rod is rotatably connected to the base.

[0008] Based on the above features, the seat cushion bracket and the backrest bracket can move independently relative to the base, allowing the seat back to better fit the passenger's back. When the backrest needs to be folded down, the seat cushion bracket can be moved away from the backrest bracket, increasing the distance between the seat cushion and the backrest, thereby creating a certain amount of space between the seat cushion and the backrest. When the backrest is folded down, the lumbar support and other structures on the backrest can be accommodated in the vacated space, making it easier to fold the backrest down. This also helps to reduce the overall height of the seat after the backrest is folded down, reducing the space occupied in the vehicle, increasing the passenger's room for movement, and reducing obstruction to other passengers' vision.

[0009] In some examples, the base includes two opposing support plates. Each support plate has a guide slot, the length of which is aligned with the direction of movement of the seat cushion bracket. The seat cushion bracket is positioned between the two support plates, and a first connecting shaft is positioned on a side of the seat cushion bracket proximate to the support plates, the first connecting shaft being positioned in the guide slot.

[0010] Based on the above features, the support plate, connecting rod, and seat cushion bracket form a three-bar linkage. As the seat cushion bracket moves, the first connecting shaft moves within the guide slot, thereby limiting the seat cushion bracket's range of motion and enabling it to move along the guide slot. Furthermore, the coordination between the first connecting shaft and the guide slot ensures that, during rotation of the connecting rod, the seat cushion bracket not only moves along the guide slot but also rotates relative to the base about the first connecting shaft.

[0011] Optionally, the support plate includes a main body and a connecting portion. The guide slot is located in the main body, the connecting portion is connected to a side edge of the main body, and the backrest bracket is hingedly connected to the connecting portion. The main body supports the seat cushion bracket, and the connecting portion facilitates the installation of the backrest bracket.

[0012] As an example, the connecting portion has a connecting hole. The backrest bracket is connected to a second connecting shaft, which is inserted into the connecting hole, so that the backrest bracket can rotate relative to the base around the second connecting shaft.

[0013] Optionally, the base further comprises a first slide rail connected to the support plate. By connecting the first slide rail to the support plate, the seat assembly can be moved relative to the vehicle via the first slide rail, thereby adjusting the position of the seat on the vehicle.

[0014] In some examples, the length of the guide slot is parallel to or at an acute angle to the first rail. By varying the angle between the guide slot and the first rail, the motion trajectory of the seat cushion bracket can be altered, and the seat cushion bracket's height can be adjusted. The angle here specifically refers to the minimum positive angle formed by the guide slot and the first rail.

[0015] In another example, the base includes a support plate and a bottom plate, wherein the two support plates are located on the same surface of the bottom plate and are vertically connected to the bottom plate. The bottom plate provides a more stable structure for the base. When the seat assembly is installed in a vehicle, the bottom plate can be fixed to the floor of the vehicle, thereby firmly connecting the seat assembly to the vehicle.

[0016] Optionally, the length of the guide slot is parallel to or at an acute angle to the base plate. By varying the angle between the guide slot and the base plate, the motion trajectory of the seat cushion bracket can be altered and the seat cushion bracket's height adjusted. The angle here specifically refers to the minimum positive angle formed by the guide slot and the base plate.

[0017] In a possible example, the base further includes a second slide rail, which is located on a side of the bottom plate away from the support plate and is connected to the bottom plate.

[0018] Based on the above features, when the seat assembly is installed on a vehicle, it can be installed via the second slide rail, thereby being able to adjust the position of the seat on the vehicle.

[0019] Optionally, the seat assembly further comprises a first drive mechanism, the first drive mechanism being in driving connection with the connecting rod. The first drive mechanism is configured to drive the connecting rod to rotate relative to the base. By providing the first drive mechanism to drive the connecting rod, the seat cushion bracket can be adjusted more easily.

[0020] Optionally, the seat assembly further includes a second drive mechanism, the second drive mechanism being in transmission connection with the backrest bracket, the second drive mechanism being configured to drive the backrest bracket to rotate relative to the base. By providing the second drive mechanism to drive the backrest bracket, the backrest bracket is driven to rotate relative to the base, thereby facilitating adjustment of the backrest angle.

[0021] Exemplarily, the first drive mechanism and the second drive mechanism both include motors and are driven by electricity to facilitate control of the seat.

[0022] In a second aspect, a seat is provided, comprising a seat cushion, a back cushion, and the seat assembly described in the first aspect, wherein the seat cushion is connected to the seat cushion bracket, and the back cushion is connected to the backrest bracket. Based on the above features, when the backrest is folded down, the seat cushion bracket first moves away from the backrest bracket, freeing up a larger space at the rear edge of the seat cushion bracket. After the backrest is folded down, the raised portion of the back cushion surface is located in the space freed up at the rear edge of the seat cushion bracket, thereby reducing the overall height of the seat after the backrest is folded down.

[0023] In a third aspect, a seat control method is provided, the method comprising: controlling a seat cushion bracket of a first seat to move relative to a base in a direction away from a backrest bracket, wherein the first seat is the seat described in the second aspect. Controlling the backrest bracket of the first seat to rotate toward the seat cushion bracket so that the back cushion of the first seat is aligned with the seat cushion. This method can control the first seat to fold, causing the backrest of the first seat to recline, thereby reducing the overall height of the seat when the backrest is reclined.

[0024] Optionally, the control method further comprises controlling the first seat to move forward or backward in the vehicle, that is, controlling the first seat to move horizontally to make the seat more convenient to use.

[0025] As an example, for a device including both a first seat and a second seat, the control method further includes:

[0026] The backrest support of a second seat is controlled to rotate away from the seat cushion support. The second seat is the seat described in the second aspect. The seat cushion support of the second seat is controlled to move relative to the base in a direction toward the backrest support. This method can both control the first seat to recline and the second seat to deploy.

[0027] In a fourth aspect, a seat control device is provided, comprising a seat control module. The seat control module is configured to execute the control method described in the third aspect. The seat control module is configured to control a seat cushion support of a first seat, which is the seat described in the second aspect, to move away from a backrest support relative to a base; and to control the backrest support of the first seat to rotate toward the seat cushion support, so that the back cushion of the first seat faces the seat cushion.

[0028] Optionally, the seat control module is further configured to control the translation of the first seat, that is, to control the translation of the first seat to facilitate use of the seat.

[0029] As an example, for a device that includes both a first seat and a second seat, the seat control module is also used to control the backrest bracket of the second seat to rotate in a direction away from the cushion bracket, and the second seat is the seat described in the second aspect; and to control the cushion bracket of the second seat to move relative to the base in a direction close to the backrest bracket.

[0030] As an example, the seat control module is a functional module in a driving computer. In other examples, the seat control module may also be a functional module in a controller for controlling the seat.

[0031] In a fifth aspect, a vehicle is provided, comprising at least one seat as described in the second aspect. The vehicle may be, but is not limited to, a car, an airplane, or a ship.

[0032] In a sixth aspect, a control device is provided, comprising a processor and a memory, wherein the memory is used to store a software program, and the processor runs or executes the software program stored in the memory so that the control device implements the method described in the third aspect.

[0033] In a seventh aspect, a computer-readable storage medium is provided, wherein the computer-readable storage medium is used to store program code executed by a processor, wherein the program code includes instructions for implementing the method described in the third aspect.

[0034] In an eighth aspect, a computer program product is provided, which includes a program code. When a computer runs the computer program product, the computer executes the method described in the third aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] FIG1 is a structural diagram of a seat assembly provided in an embodiment of the present application. As shown in FIG1 , the seat assembly includes a base 10 , a seat cushion bracket 20 , a backrest bracket 30 and a connecting rod 40 .

[0050] The seat includes a seat cushion and a backrest. The seat cushion bracket 20 in the embodiment of the present application refers to a hard structure in the seat cushion that bears the load and maintains the shape of the seat cushion, which is equivalent to the skeleton of the seat cushion. The backrest bracket 30 refers to a hard structure in the backrest of the seat that bears the load and maintains the shape of the backrest, which is equivalent to the skeleton of the backrest. In order to ensure sufficient comfort, the seat cushion bracket 20 and the backrest bracket 30 are usually provided with a leather, cloth or other skin structure on the surface. In order to further improve the comfort of some seats, the inside of the seat cushion and the backrest can be filled with flexible fillers. The seat cushion bracket 20 can be the part of the seat cushion after removing the skin structure and the flexible filler, and the backrest bracket 30 can be the part of the backrest after removing the skin structure and the flexible filler. Exemplarily, the seat cushion bracket 20 and the backrest bracket 30 are both made of metal materials, such as stainless steel, aluminum alloy, etc.

[0051] The backrest bracket 30 is rotatably connected to the base 10 . The backrest bracket 30 can rotate relative to the base 10 to adjust the angle of the backrest bracket 30 .

[0052] The seat cushion bracket 20 has a rear edge 20a close to the backrest bracket 30 and a front edge 20b opposite to the rear edge 20a. When a passenger normally uses the seat, he sits on the seat cushion, with the front edge 20b of the seat cushion bracket 20 close to the passenger's knees and the rear edge 20a of the seat cushion bracket 20 close to the passenger's buttocks.

[0053] The seat cushion bracket 20 is rectangular or approximately rectangular. The front edge 20b of the seat cushion bracket 20 can be the side of the seat cushion bracket 20 close to the front of the seat, and the rear edge 20a of the seat cushion bracket 20 can be the side of the seat cushion bracket 20 close to the rear of the seat.

[0054] The seat cushion bracket 20 is movably connected to the base 10, and the seat cushion bracket 20 can move relative to the base 10 in a direction close to or away from the backrest bracket 30. The first connection between the seat cushion bracket 20 and the base 10 is close to the rear edge 20a of the seat cushion bracket 20.

[0055] One end of the connecting rod 40 is rotatably connected to the seat cushion bracket 20 at a second connection point, and the second connection point is close to the front edge 20 b of the seat cushion bracket 20 . The other end of the connecting rod 40 is rotatably connected to the base 10 .

[0056] The seat cushion bracket 20 is connected to the base 10 and the connecting rod 40, respectively. The seat cushion bracket 20 has a first connection and a second connection. The first connection is the connection between the seat cushion bracket 20 and the base 10, and the second connection is the connection between the seat cushion bracket 20 and the connecting rod 40. Of the first and second connections, the first connection is closer to the rear edge 20a of the seat cushion bracket 20, while the second connection is closer to the front edge 20b of the seat cushion bracket 20. There can be multiple first connections. For example, as shown in FIG1 , there is a first connection on each side of the seat cushion bracket 20 connected to the base 10. There can also be multiple second connections. Also as shown in FIG1 , there is a second connection on each side of the seat cushion bracket 20. The seat assembly includes two connecting rods 40, which are arranged on either side of the seat cushion bracket 20 and connected to the seat cushion bracket 20 at the second connection.

[0057] Figure 2 is a schematic diagram illustrating the movement of a seat assembly according to an embodiment of the present application. As shown in Figure 2 , by separately mounting a seat cushion bracket 20 and a backrest bracket 30 on a base 10, the seat cushion bracket 20 and the backrest bracket 30 can independently move relative to the base 10. For example, while the seat cushion bracket 20 remains stationary, the backrest bracket 30 can be rotated relative to the base 10 to adjust the angle of the backrest bracket 30, thereby changing the seat backrest angle and ensuring a better fit for the passenger's back.

[0058] Because the ends of the connecting rod 40 are rotatably connected to the seat cushion bracket 20 and the base 10, respectively, the height of the seat cushion bracket 20 can be changed by rotating the connecting rod 40, and thus the height of the seat cushion can be adjusted to suit different passenger needs. In addition, the seat cushion bracket 20 can be moved relative to the base 10 in a direction closer to or away from the backrest bracket 30. Therefore, when the backrest needs to be folded down, the seat cushion bracket 20 can be moved away from the backrest bracket 30, thereby increasing the distance between the seat cushion and the backrest, thereby freeing up a certain amount of space between the seat cushion and the backrest. When the backrest is folded down, the lumbar support and other structures on the backrest can be accommodated in the freed-up space, making it easier to fold the backrest down. This also helps to reduce the overall height of the seat after the backrest is folded down, reducing the space occupied in the vehicle, increasing the passenger's mobility space, and reducing the obstruction of other passengers' vision.

[0059] As shown in FIG1 , the base 10 includes two support plates 11 , which are arranged opposite to each other and have guide slots 111 a . The length direction of the guide slots 111 a is the same as the moving direction of the seat cushion bracket 20 .

[0060] The seat cushion bracket 20 is located between the two support plates 11 . A side of the seat cushion bracket 20 close to the support plate 11 has a first connecting shaft 21 . The first connecting shaft 21 is located in the guide slot 111 a .

[0061] The two support plates 11 support the seat cushion bracket 20. A guide slot 111a is provided on the support plate 11 to limit the movement of the seat cushion bracket 20. A first connecting shaft 21 is arranged on the side of the seat cushion bracket 20 close to the support plate 11. The first connecting shaft 21 is also located in the guide slot 111a. The guide slot 111a and the first connecting shaft 21 cooperate. When the seat cushion bracket 20 moves, the first connecting shaft 21 moves within the guide slot 111a, thereby limiting the range of motion of the seat cushion bracket 20 and allowing the seat cushion bracket 20 to move along the guide slot 111a. Furthermore, the cooperation between the first connecting shaft 21 and the guide slot 111a ensures that, during rotation, the connecting rod 40 not only drives the seat cushion bracket 20 to move along the guide slot 111a but also allows it to rotate relative to the base 10 about the first connecting shaft 21. In other words, the support plate 11, the connecting rod 40, and the seat cushion bracket 20 constitute a linkage mechanism.

[0062] Illustratively, there is a clearance fit between the guide slot 111 a and the first connecting shaft 21 , so that the first connecting shaft 21 can move easily in the guide slot 111 a with little resistance and smooth movement.

[0063] In some examples, a first connecting shaft 21 may be provided on both sides of the seat cushion bracket 20, that is, two first connecting shafts 21 are provided, and the two first connecting shafts 21 are respectively located in the guide grooves 111a of the two support plates 11, and the two first connecting shafts 21 are coaxially arranged.

[0064] In other examples, only one first connecting shaft 21 may be provided, and the first connecting shaft 21 passes through the seat cushion bracket 20. The two ends of the first connecting shaft 21 are respectively located in the guide slots 111a of the two support plates 11.

[0065] As shown in FIG1 , the support plate 11 includes a main body 111 and a connecting portion 112. The guide slot 111a is located in the main body 111, and the connecting portion 112 is connected to a side edge of the main body 111. The backrest bracket 30 is hinged to the connecting portion 112.

[0066] The main body 111 is provided with a guide slot 111a and is used to mount the seat cushion bracket 20. The connecting rod 40 is also rotatably connected to the main body 111. The connecting portion 112 is used to mount the backrest bracket 30. The structure of the connecting portion 112 only needs to be able to connect with the backrest bracket 30 and enable the backrest bracket 30 to rotate relative to the base 10.

[0067] For example, the connecting portion 112 may have a connecting hole 112 a . A second connecting shaft 31 may be connected to one side of the backrest bracket 30 near the connecting portion 112 . The second connecting shaft 31 is inserted into the connecting hole 112 a so that the backrest bracket 30 can rotate relative to the base 10 around the second connecting shaft 31 .

[0068] In some examples, a second connecting shaft 31 may be provided on both sides of the backrest bracket 30, that is, two second connecting shafts 31 are provided, and the two second connecting shafts 31 are respectively located in the connecting holes 112a of the connecting parts 112 of the two support plates 11, and the two second connecting shafts 31 are coaxially arranged.

[0069] In other examples, only one second connecting shaft 31 may be provided, and the second connecting shaft 31 passes through the backrest bracket 30. Both ends of the second connecting shaft 31 are respectively located in the connecting holes 112a of the connecting portions 112 of the two support plates 11.

[0070] FIG3 is a side view of a seat assembly provided by an embodiment of the present application. As shown in FIG3 , in the seat assembly, the base 10 further includes a first slide rail 12 , and the first slide rail 12 is connected to the support plate 11 .

[0071] In the embodiment of the present application, the base 10 includes two support plates 11 and two first slide rails 12 , and the two first slide rails 12 are connected to the two support plates 11 in a one-to-one correspondence.

[0072] The first slide rail 12 is located at the bottom of the support plate 11. Here, the bottom of the support plate 11 refers to the bottom of the support plate 11 when the chair is placed upright.

[0073] By connecting the first slide rail 12 to the support plate 11, the seat assembly can be mounted on the vehicle via the first slide rail 12, and the seat assembly can be moved relative to the vehicle via the first slide rail 12, thereby adjusting the position of the seat on the vehicle. For example, the seat can be moved in the front-to-back direction of the vehicle, thereby adjusting the position in the front-to-back direction.

[0074] As an example, Figure 4 is a schematic diagram of the structure of a first slide rail provided in an embodiment of the present application. As shown in Figure 4, the first slide rail 12 may include a fixed portion 121 and a sliding portion 122. The sliding portion 122 is slidably connected to the fixed portion 121 and is capable of sliding relative to the fixed portion 121. The sliding portion 122 is connected to the support plate 11, and the fixed portion 121 is used to be mounted to the floor of the vehicle, thereby enabling the seat assembly to slide relative to the floor of the vehicle.

[0075] For example, the fixing portion 121 can be fixed to the floor of the vehicle by bolts, or can also be fixed by welding, etc. The sliding portion 122 can also be connected to the support plate 122 by bolts, or welded to the support plate 122 by welding.

[0076] As shown in FIG. 3 , the length direction of the guide slot 111 a on the support plate 11 is parallel to the first slide rail 12 .

[0077] The guide slot 111a guides the movement of the seat cushion bracket 20. As the seat cushion bracket 20 moves relative to the base 10, the first connecting shaft 21 moves along the length of the guide slot 111a. The length of the guide slot 111a is parallel to the first rail 12. Therefore, after the seat assembly is installed via the first rail 12, the height of the first connecting shaft 21 remains constant during movement of the seat cushion bracket 20, relative to the position of the first rail 12.

[0078] FIG5 is a side view of a seat assembly provided by an embodiment of the present application. As shown in FIG5 , in this example, the length direction of the guide slot 111 a on the support plate 11 forms an acute angle with the first slide rail 12 .

[0079] The angle between the length of the guide groove 111a and the first rail 12 refers to the minimum positive angle formed by the length of the guide groove 111a and the first rail 12. For example, two intersecting straight lines form two angles on either side of each line, and the sum of these two angles is 180°. The smaller angle is the angle between the two lines. In other words, the maximum angle is 90°. In this example, the angle between the length of the guide groove 111a and the first rail 12 is less than 90°.

[0080] In this example, after the seat assembly is installed through the first slide rail 12, with the position of the first slide rail 12 as a reference, the height of the first connecting shaft 21 will continue to change during the movement of the seat cushion bracket 20, which allows the height of the seat assembly to change.

[0081] In the example shown in FIG5 , the height of the guide slot 111a at the end near the connecting rod 40 is less than the height at the end near the backrest bracket 30. This causes the seat cushion bracket 20 to rise as it approaches the backrest bracket 30. As the seat cushion bracket 20 moves away from the backrest bracket 30, its height decreases. This allows the seat cushion bracket 20 to free up more space to accommodate the backrest when the backrest bracket 30 is folded down, further reducing the overall height of the seat when the backrest is folded down. This reduces the space occupied in the vehicle, increases passenger mobility, and reduces obstruction to other passengers' vision.

[0082] Figure 6 is a side view of a seat assembly provided by an embodiment of the present application. Compared to the example shown in Figure 5 , in the example shown in Figure 6 , the guide slot 111a is higher near the connecting rod 40 than near the backrest bracket 30. This allows the rear edge 20a of the seat cushion bracket 20 to lower as the seat cushion bracket 20 approaches the backrest bracket 30. This allows a passenger's center of gravity to be closer to the backrest, allowing them to lean further back, improving seat comfort.

[0083] FIG7 is a side view of a seat assembly provided in an embodiment of the present application. As shown in FIG7 , in the seat assembly, the base 10 further includes a bottom plate 13. Two support plates 11 are located on the same surface of the bottom plate 13 and are vertically connected to the bottom plate 13.

[0084] The bottom plate 13 is positioned at the bottom of the two support plates 11. The arrangement of the bottom plate 13 can make the structure of the base 10 more stable. When the seat assembly is installed on a vehicle, the bottom plate 13 can be fixed to the floor in the vehicle, thereby making the seat assembly firmly connected to the vehicle.

[0085] For example, the bottom plate 13 may have a plurality of fixing holes 13 a , and the bottom plate 13 may be fixed to the floor of the vehicle by bolts 14 .

[0086] In some examples, the length direction of the guide slot 111a on the support plate 11 is parallel to the bottom plate 13. In this way, after the seat assembly is installed through the bottom plate 13, the height of the first connecting shaft 21 remains unchanged during the movement of the seat cushion bracket 20 with the position of the bottom plate 13 as a reference.

[0087] In other examples, the lengthwise direction of the guide slot 111a on the support plate 11 forms an acute angle with the base plate 13. The angle between the lengthwise direction of the guide slot 111a and the base plate 13 is the minimum positive angle formed by the lengthwise direction of the guide slot 111a and the base plate 13, that is, the maximum angle is 90°. In this example, the angle between the lengthwise direction of the guide slot 111a and the base plate 13 is less than 90°. This allows the height of the first connecting shaft 21 to continuously change during movement of the seat cushion bracket 20, thereby enabling the seat assembly to vary in height.

[0088] Figure 8 is a side view of a seat assembly provided in an embodiment of the present application. As shown in Figure 8, compared with the seat assembly shown in Figure 7, in this seat assembly, the base 10 also includes a second slide rail 15, and the second slide rail 15 is located on the side of the bottom plate 13 away from the support plate 11, and the second slide rail 15 is connected to the bottom plate 13.

[0089] By disposing the second slide rail 15 on the bottom of the base plate 13, i.e., on the side of the base plate 13 facing away from the support plate 11, the seat assembly can be installed in a vehicle without connecting the base plate 13 to the vehicle floor. Instead, the seat assembly can be installed using the second slide rail 15, thereby allowing the seat to be adjusted in the vehicle. For example, in the example shown in FIG8 , the second slide rail 15 is perpendicular to the first connecting shaft 21, allowing the seat to move in the fore-aft direction of the vehicle, thereby adjusting its fore-aft position.

[0090] In other examples, the second slide rail 15 may also be arranged in other directions. For example, the second slide rail 15 is arranged parallel to the first connecting shaft 21 so that the seat can move in the left-right direction of the vehicle.

[0091] In addition, since both the base plate 13 and the second slide rail 15 are provided, when the position of the seat does not need to be adjusted, the base plate 13 can be connected to the vehicle body to lock the seat and make the seat more stable. For example, the base plate 13 can be connected to the floor of the vehicle by bolts 14.

[0092] As an example, the second slide rail 15 may also include a fixed portion and a sliding portion. The structure of the second slide rail 15 may refer to the first slide rail 12 shown in FIG. 4 , and will not be described in detail here.

[0093] FIG9 is a schematic structural diagram of a seat assembly provided by an embodiment of the present application. As shown in FIG9 , the seat assembly may further include a first drive mechanism 50 , which is in transmission connection with the connecting rod 40 and is used to drive the connecting rod 40 to rotate relative to the base 10 .

[0094] By providing a first driving mechanism 50 to drive the connecting rod 40 , the seat cushion bracket 20 is driven to move relative to the base 10 in a direction close to or away from the backrest bracket 30 , thereby facilitating adjustment of the seat.

[0095] For example, the first driving mechanism 50 may include a motor and a gearbox. The motor's rotating shaft is connected to the input shaft of the gearbox, and the output shaft of the gearbox can be in driving connection with the connecting rod 40. The motor drives the connecting rod 40 to rotate through the gearbox.

[0096] The first driving mechanism 50 may further include a brake for braking the motor or the gear box to lock the connecting rod 40 , thereby locking the position of the seat cushion bracket 20 .

[0097] As an example, the connecting rod 40 and the base 10 can be connected via a third connecting shaft 41. The connecting rod 40 is fixedly connected to the third connecting shaft 41, and the third connecting shaft 41 is rotatably connected to the support plate 11. The third connecting shaft 41 is connected to the output shaft of the gearbox, and the output shaft of the gearbox drives the third connecting shaft 41 to rotate, thereby driving the connecting rod 40 to rotate.

[0098] Optionally, the first driving mechanism 50 may be arranged below the seat cushion bracket 20 and between the two support plates 11 to further save space.

[0099] Taking the seat assembly shown in FIG. 7 as an example, the first drive mechanism 50 may be mounted on the base plate 13 , located on a side of the base plate 13 close to the seat cushion bracket 20 , and between the two support plates 11 .

[0100] As shown in FIG. 9 , the seat assembly may further include a second driving mechanism 60 , which is in transmission connection with the backrest bracket 30 , and is configured to drive the backrest bracket 30 to rotate relative to the base 10 .

[0101] The second driving mechanism 60 is provided to drive the backrest bracket 30 , thereby driving the backrest bracket 30 to rotate relative to the base 10 , thereby facilitating adjustment of the angle of the backrest.

[0102] The second drive mechanism 60 can have the same structure as the first drive mechanism 50, also including a motor and a gearbox. The motor's rotating shaft is drivingly connected to the gearbox's input shaft, and the gearbox's output shaft is drivingly connected to the second connecting shaft 31. The second drive mechanism 60 can also include a brake for braking the motor or gearbox to lock the backrest bracket 30 in place.

[0103] Optionally, the second driving mechanism 60 may be arranged below the backrest bracket 30 and between the two support plates 11 to save space.

[0104] Taking the seat assembly shown in FIG. 7 as an example, the second drive mechanism 60 may also be mounted on the base plate 13 , located on a side of the base plate 13 close to the backrest bracket 30 , and between the two support plates 11 .

[0105] In some examples, the second drive mechanism 60 can also be arranged behind the two support plates 11, that is, on the side of the two support plates 11 away from the front edge 20b of the seat cushion bracket 20, so as to avoid the second drive mechanism 60 occupying the space directly below the backrest bracket 30 and affecting the movement of the backrest bracket 30.

[0106] Exemplarily, the second drive mechanism 60 is connected to the second connecting shaft 31 via a transmission mechanism, such as a chain transmission. As an example, a sprocket 61 is provided on the output shaft of the gearbox and the second connecting shaft 31, respectively. The sprocket 61 on the output shaft of the gearbox and the sprocket 61 on the second connecting shaft 31 are connected by a chain 62. In other examples, the second drive mechanism 60 and the second connecting shaft 31 may also be connected via a gear mechanism.

[0107] In the embodiment of the present application, two driving mechanisms are provided to control the seat cushion bracket 20 and the backrest bracket 30 respectively, so that the seat cushion bracket 20 and the backrest bracket 30 can be adjusted separately, which makes the use of the seat more convenient.

[0108] FIG10 is a schematic diagram of the structure of a seat provided in an embodiment of the present application. As shown in FIG10 , the seat includes a seat cushion 71, a back cushion 72, and any of the seat components shown in FIG1 to FIG9 , wherein the seat cushion 71 is connected to the seat cushion bracket 20, and the back cushion 72 is connected to the backrest bracket 30.

[0109] The seat cushion 71 and the seat cushion bracket 20 form the seat cushion of the seat, and the back cushion 72 and the backrest bracket 30 form the seat backrest. Both the seat cushion 71 and the back cushion 72 can be flexible, and the seat cushion 71 can be wrapped or covered outside the seat cushion bracket 20, and the back cushion 72 can be wrapped or covered outside the backrest bracket 30.

[0110] As an example, as shown in FIG10 , a seat cushion 71 can be provided on the upper surface of the seat cushion support 20, i.e., the surface of the seat cushion support 20 that is adjacent to the backrest support 30 and is also the surface of the seat cushion support 20 that is adjacent to the upper surface when the seat is placed upright. A back cushion 72 is provided on the surface of the backrest support 30 that is adjacent to the seat cushion support 20. When the backrest support 30 is folded down, the back cushion 72 faces the seat cushion 71.

[0111] The surfaces of the seat cushion 71 and back cushion 72 are typically not flat. For example, in Figure 10 , the middle portion of the back cushion 72 is raised to better support the passenger's waist and back. Because the seat cushion bracket 20 can move away from the backrest bracket 30, when the backrest is folded down, the seat cushion bracket 20 first moves away from the backrest bracket 30, freeing up a larger space at the rear edge 20a of the seat cushion bracket 20. After the backrest is folded down, the raised portion of the back cushion 72 fits neatly into the space vacated by the rear edge 20a of the seat cushion bracket 20, which helps reduce the overall height of the seat when the backrest is folded down.

[0112] Figure 11 is a flow chart of a seat control method provided by an embodiment of the present application. The seat can be a seat in a vehicle, such as a car seat; or it can be a seat indoors, such as a seat in a movie theater or a conference room. The following takes a car as an example to illustrate the control method, but it does not mean that the method is only applicable to vehicles. The car includes a first seat, and the first seat can be any seat in the car, for example, the first seat can be the front seat or the rear seat of the car. For a car with three or more rows of seats, the first seat can also be a seat between the front seat and the rear seat. The first seat is the seat shown in Figure 10. As shown in Figure 11, the control method includes:

[0113] In step S11 , the seat cushion bracket 20 of the first seat is controlled to move relative to the base 10 in a direction away from the backrest bracket 30 .

[0114] In step S12 , the backrest bracket 30 of the first seat is controlled to rotate in a direction close to the seat cushion bracket 20 , so that the back cushion 72 of the first seat faces the seat cushion 71 .

[0115] By first controlling the seat cushion bracket 20 of the first seat to move away from the backrest bracket 30, a space is created between the rear edge 20a of the seat cushion bracket 20 and the backrest bracket 30, and then controlling the backrest bracket 30 to rotate toward the seat cushion bracket 20 to fold down the backrest, it is beneficial to lower the overall height of the backrest when placed on the rear seat, reduce the space occupied in the vehicle, increase the passenger's activity space, and reduce the obstruction of the field of view of other passengers.

[0116] Optionally, the method may further include the following optional steps:

[0117] In step S13 , the first seat is controlled to move in translation.

[0118] For example, controlling the first seat to move forward or backward.

[0119] Although step S13 is performed after step S12 in the example shown in FIG11 , in other examples, step S13 may be performed before step S12, before step S11, or simultaneously with step S11 or step S12. Step S13 can adjust the position of the first seat in the vehicle.

[0120] In the embodiments of the present application, forward movement refers to movement toward the front of the vehicle, and rearward movement refers to movement toward the rear of the vehicle. For example, in a car, forward movement of the first seat refers to movement of the first seat toward the front of the vehicle, and rearward movement of the first seat refers to movement of the first seat toward the rear of the vehicle.

[0121] Typically, a car has more than one seat. For example, it may also include a second seat, which can be any seat other than the first seat. The second seat may also be the seat shown in FIG10 . FIG12 is a flow chart of a seat control method provided in an embodiment of the present application. The method is used to further control the second seat based on the control of the first seat. When controlling the seat, as shown in FIG12 , the control method may also include the following optional steps:

[0122] In step S14 , the backrest bracket 30 of the second seat is controlled to rotate in a direction away from the seat cushion bracket 20 .

[0123] In step S15 , the seat cushion bracket 20 of the second seat is controlled to move relative to the base 10 in a direction approaching the backrest bracket 30 .

[0124] Step S14 may be performed after step S12, or may be performed simultaneously with step S11 or step S12. Through steps S14 and S15, the second seat is controlled to unfold so that the passenger can sit on the second seat normally.

[0125] In addition, the second seat can also be controlled to move forward or backward to adjust the position of the second seat in the vehicle.

[0126] The present application also provides a seat control device comprising a seat control module. The seat control module is configured to execute the control method shown in FIG11 or FIG12 . The seat control module is configured to control the seat cushion support of a first seat to move relative to the base in a direction away from the backrest support, and to control the backrest support of the first seat to rotate toward the seat cushion support, so that the back cushion of the first seat faces the seat cushion. Specifically, the seat control module is configured to execute steps S11 to S12 described above.

[0127] Optionally, the seat control module is further configured to control the translation of the first seat, that is, the seat control module is further configured to execute the aforementioned step S13 to control the translation of the first seat to facilitate use of the seat.

[0128] Furthermore, for an apparatus including both a first seat and a second seat, the seat control module is further configured to control the second seat's backrest bracket to rotate away from the seat cushion bracket, and to control the second seat's seat cushion bracket to move relative to the base in a direction toward the backrest bracket. In other words, the seat control module is further configured to execute steps S14 and S15 described above.

[0129] The above-mentioned seat control device and seat control method belong to the same concept. The specific implementation process is detailed in the method embodiment and will not be repeated here.

The seat control device can also be a controller specifically designed to control the seat, and the seat control module can be a functional module within that controller. The controller can be located on the instrument panel, on one side of the seat, in the door, or in the center console.
