Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of automobiles. Background Art
[0002] With the development of society and the continuous improvement of people's living standards, cars have gradually become an important way for people to travel, and as a result, people have higher and higher requirements for car comfort.
[0003] Car seats are an important factor affecting riding comfort. Most cars are designed with five seats, divided into two front seats for the driver and the co-driver, and three passenger seats in the back. Due to the limitations of the car's structure and wheelbase, the back seats are relatively compact, with less legroom. The angle of the back seat backrest cannot be adjusted or can only be slightly adjusted, which makes long-term riding very uncomfortable. To solve the above problems, some car manufacturers lengthen the wheelbase to increase the legroom of the back seat at the expense of affecting driving control. However, due to the angle of the back seat backrest, the above measures do not significantly improve passenger comfort.
[0004] Since the rear seats are rarely filled with three people and are often occupied by only one or two people, some luxury cars design the rear seats as two-seaters. Some car manufacturers also design the middle seat in the rear row to be smaller and provide a movable armrest on the back. Although the above changes increase the lateral space for the rear passengers, they still cannot improve the comfort of the passengers' legs, feet and backs.
[0005] In view of the above problems, it is necessary to design a rear seat suitable for cars that can improve the comfort of passengers. Summary of the invention
[0006] The object of the present invention is to provide a vehicle with a variable rear seat to improve the comfort of rear passengers.
[0007] The automobile with variable rear seats of the present invention includes rear seats installed in the rear position of the automobile. The key point is that the rear seats include variable seats with seat posture adjustment function and fixed seats located next to the variable seats. The rear row of the automobile is provided with a first guide rail, and a rotating support device is movably installed on the first guide rail. The variable seat is fixed on the rotating support device.
[0008] The above-mentioned variable seat can move along the first guide rail, so that the space beside the seat assembly is increased, and then the angle is changed by rotating the supporting device so that the variable seat is inclined to the central axis of the vehicle body. At this time, the variable seat can be deformed into a reclining chair by adjusting the seat back angle and the seat cushion angle. When the passenger is on the reclining chair, the legs, feet, shoulders and back can be stretched, thereby dispersing the pressure of the human body on the legs and back, thereby improving comfort.
[0009] Furthermore, the first guide rail extends to the bottom of the fixed seat along the width direction of the vehicle body, and the seat cushion of the fixed seat is a detachable seat cushion or a foldable seat cushion. The seat cushion of the fixed seat beside the variable seat is set as a detachable seat cushion or a foldable seat cushion, so that when the variable seat needs to be moved and occupies the space of the fixed seat, the seat cushion of the fixed seat can be removed or folded to avoid interference with the variable seat.
[0010] Specifically, the rear seat consists of the variable seat located at one side, the first fixed seat located at the center, and the second fixed seat located at the other side. The first guide rail extends to the bottom of the first fixed seat, and the seat cushion of the first fixed seat is a detachable seat cushion or a foldable seat cushion; the rotation support device consists of a bottom plate movably mounted on the first guide rail, a second guide rail arranged on the top surface of the bottom plate and extending along the length direction of the vehicle body, a top plate movably mounted on the second guide rail, and a rotation mechanism arranged on the top plate; the variable seat is fixed on the rotation mechanism; a support block for supporting the rear position of the variable seat is provided at the rear position of the car corresponding to the position of the variable seat.
[0011] When converting the variable seat into a reclining chair, first remove the seat cushion of the first fixed seat or fold it upward to expose the first guide rail under the seat cushion of the first fixed seat; then move the top plate forward to align the top plate with the bottom plate. At this time, the position of the variable seat has avoided the backrest position of the first fixed seat, so it can be moved laterally along the first guide rail; after the variable seat is moved to the middle or other suitable position, the variable seat can be rotated and the angle of its backrest can be adjusted to convert it into a reclining chair. In order to reduce the space occupied by the variable seat and increase the angle of its backrest adjustment, it is best to lower its headrest to the lowest position.
[0012] After the variable seat is converted into a reclining chair, since the axial direction of the variable seat is tilted to the direction of the car's travel at this time, if the variable seat is in a horizontal state, then when the car brakes, the passengers on it are easy to roll off the seat due to inertia. To solve this problem, in the present invention, the bottom plate is movably mounted on the first guide rail through a lifting frame, and the lifting frame is formed by a front lifting frame and a rear lifting frame connected by a connecting rod. The front lifting frame and the rear lifting frame are both provided with a lifting drive mechanism, and the rear lifting frame is an elastic frame. By adjusting the height of the front lifting frame and the rear lifting frame, as well as the weight distribution of the passenger on the reclining chair, the variable seat is made into a slightly tilted state with the front higher and the rear lower. In this way, when the car brakes, because the rear lifting frame is elastic, it will be more tilted due to inertia, and the passenger is not easy to roll off the variable seat, thereby improving safety. Setting the rear lifting frame as an elastic frame can also form a certain buffer when the car starts and brakes, so as to improve the comfort of the passengers.
[0013] Furthermore, in order to ensure safety, the present invention is also provided with a device for supporting the lifting frame and preventing the lifting frame from tipping forward when the vehicle brakes suddenly. Specifically, there are two ways:
[0014] 1. A third guide rail extending along the length direction of the vehicle body is provided on the front floor of the first fixed seat, and a support assembly is installed on the third guide rail. The support assembly is formed by connecting a front support plate and a rear support plate through a rotating shaft, and the bottom end of the front support plate is movably mounted on the third guide rail, and the bottom end of the rear support plate is fixed on the third guide rail; the support assembly is also provided with a horizontal driving mechanism for driving the bottom end of the front support plate to move along the third guide rail. When the horizontal driving mechanism drives the bottom end of the front support plate to move backward along the third guide rail, the connection between the front support plate and the rear support plate can be gradually raised, and finally a triangular structure is formed. At this time, the top end of the rear support plate abuts against the front lifting bracket or the front lower part of the bottom plate to provide support for the lifting bracket. The above-mentioned horizontal driving mechanism can be composed of a motor and a driving rod extending along the length direction of the vehicle body. The rotating shaft of the motor and the driving rod are matched through gears and racks. The rotation of the motor drives the driving rod to move horizontally. The end of the driving rod is movably connected to the bottom end of the front support plate through a ring or a limit groove, thereby driving the bottom end of the front support plate to move.
[0015] 2. A trapezoidal cabinet is provided on the floor in front of the first fixed seat, and a rearward-inclined lifting plate and a vertical driving mechanism for driving the lifting plate to rise and fall are provided inside the trapezoidal cabinet. After the vertical driving mechanism raises the lifting plate, the top of the lifting plate abuts against the front lifting bracket to provide support for the lifting frame. The vertical driving mechanism can be composed of a motor, and the rotating shaft of the motor cooperates with the lifting plate through gears and racks, and the rotation of the motor drives the lifting plate to move.
[0016] Furthermore, a third fixed seat is provided in front of the second fixed seat, a fourth vertical rail is provided on the backrest of the third fixed seat, a leg and foot support box is provided on the fourth rail, and the leg and foot support box is formed by five panels arranged up and down and connected in sequence through horizontal hinges, the top of the top panel is fixedly connected to the backrest of the third fixed seat; the bottom panel is movably mounted on the fourth rail and connected to the support box driving mechanism. When the support box driving mechanism drives the bottom panel to move upward along the fourth rail, the five panels can be folded into a box structure with openings at both ends, and the passengers on the variable seat can extend their feet into the leg and foot support box to improve comfort. When the support box driving mechanism drives the bottom panel to move downward along the fourth rail, the five panels can be flattened into a flat plate close to the back of the backrest of the third fixed seat to reduce the occupied space. The support box driving mechanism is a vertical driving mechanism for transmission, which will not be described in detail here.
[0017] Furthermore, the bottommost plate is installed with a top block, the top of which is a plane, and the top surface of the top block is against the bottom plate of the leg and foot support box (i.e. the fourth plate from top to bottom), which can form a stable and strong support to ensure the stability of the leg and foot support box.
[0018] Furthermore, both sides of the backrest of the variable seat are provided with armrest grooves with the opening direction facing the front of the car, and the armrests are provided in the armrest grooves. The armrests are composed of two hard plates at the bottom and the top and an elastic strip connecting the two hard plates, and the hard plate at the bottom is movably connected to the backrest of the variable seat through a rotating shaft. When the armrest is needed, the armrest can be rotated out of the armrest groove, and the upper hard plate of the armrest can be folded outward and downward into a right angle under the pressure of the arm to support the passenger's arm and improve comfort; and after the passenger moves his arm away, the upper hard plate quickly returns to a state of being tightly attached to the bottom hard plate under the elastic force of the elastic strip, so as to be conveniently retracted into the armrest groove. By folding the deformable armrest, the width of the armrest groove can be reduced, thereby reducing the width occupied by the chair back.
[0019] Furthermore, a retractable leg rest and a retractable foot rest are provided in the seat cushion of the variable seat. After the variable seat is converted into a reclining chair, the leg rest and the foot rest can be extended to facilitate passengers to place their legs and feet and improve comfort. The retractable leg rest and the retractable foot rest are both prior art and will not be described in detail here.
[0020] Furthermore, the first fixed seat and the second fixed seat are both provided with sensors for detecting whether there is someone sitting on the seat, and the sensors are connected to a controller provided on the variable seat. The controller is used to control the seat back angle, seat cushion angle, headrest height, rotation support device, lifting frame, horizontal drive mechanism, vertical drive mechanism, and tray drive mechanism of the variable seat. The controller can detect whether there is someone sitting on the second fixed seat and the third fixed seat through the sensors, and thus decide to adopt an appropriate mode (for example, single-person mode, double-person mode, triple-person mode) to control the movement of the variable seat.
[0021] The automobile of the present invention can convert the variable rear seats in the rear seats into reclining chairs while maintaining the functions of the existing traditional rear three-person seats, thereby improving the comfort of the rear passengers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The following is a detailed description of the specific implementation of the present invention, such as the shape, structure, relative position and connection relationship of each component involved, the function and working principle of each component, etc., through the description of the implementation examples with reference to the accompanying drawings.
[0029] Embodiment 1:
[0030] This embodiment provides a car with variable rear seats to improve the comfort of rear passengers.
[0031] The automobile with variable rear seats of the present invention includes rear seats installed in the rear position of the automobile. In this embodiment, the rear seats refer to the second row behind the driver's seat and the co-driver's seat or any row of seats behind the second row, such as Figure 1 As shown, the rear seat consists of a variable seat 1 located at one side, a first fixed seat 2 located at the center, and a second fixed seat 3 located at the other side, wherein the first fixed seat 2 and the second fixed seat 3 are common seats in current cars, which can be one-piece seats or split seats, and the seat cushion of the first fixed seat 2 is a detachable seat cushion or a foldable seat cushion; the variable seat 1 has a seat posture adjustment function (including a backrest angle adjustment function and a seat cushion angle adjustment function, etc.), and the seat cushion of the variable seat 1 is provided with a telescopic leg rest 4 and a telescopic foot rest 5. After the variable seat 1 is converted into a reclining chair, the leg rest 4 and the foot rest 5 can be extended to facilitate passengers to place their legs and feet and improve comfort. The above-mentioned seat posture adjustment function, telescopic leg rest 4 and telescopic foot rest 5 are all prior art and will not be repeated here.
[0032] like Figure 2As shown, a first guide rail 6 extending in the width direction of the vehicle body is provided on the floor of the rear row of the vehicle. The first guide rail 6 extends from the bottom of the variable seat 1 to the bottom of the first fixed seat 2. The first guide rail 6 is preferably a W-rail or a high-low rail, which is relatively strong. A rotation support device is movably mounted on the first guide rail 6, and the variable seat 1 is fixed on the rotation support device. Specifically, the rotation support device consists of a bottom plate 8 movably mounted on the first guide rail 6 through a lifting frame 7, a second guide rail 9 disposed on the top surface of the bottom plate 8 and extending in the length direction of the vehicle body, a top plate 10 movably mounted on the second guide rail 9, and a rotation mechanism 11 disposed on the top plate 10. The variable seat 1 is fixed on the rotation mechanism 11. As shown Figure 3 As shown, the lifting frame 7 is formed by connecting the front lifting frame and the rear lifting frame through a connecting rod. The front lifting frame and the rear lifting frame are both "X"-shaped frames formed by connecting metal rods through a rotating shaft, and are provided with a lifting drive mechanism. The rear lifting frame is an elastic frame made of elastic metal rods, and the front lifting frame can be an elastic frame or a non-elastic frame. Of course, the front lifting frame and the rear lifting frame can also be frames of other shapes as long as they have the functions of lifting and supporting.
[0033] A support block 12 for supporting the rear position of the variable seat 1 is provided below the position corresponding to the variable seat 1 in the rear position of the car. The support block 12 is used to serve as a force point at the rear of the top plate 10 in a normal state (that is, when the variable seat 1 has not been transformed into a reclining chair), thereby supporting the rear position of the variable seat 1.
[0034] By adjusting the height of the front lifting bracket and the rear lifting bracket, when the variable seat 1 is transformed into a reclining state, the weight distribution of the passenger on the reclining chair makes the variable seat 1 slightly tilted with the front higher and the rear lower. In this way, when the car brakes, because the rear lifting bracket is elastic, it will be more tilted due to inertia, and the passenger is not likely to roll off the seat, thereby improving safety. The rear lifting bracket is set as an elastic bracket, and a certain buffer can also be formed when the car starts and brakes, so as to improve the comfort of the passengers.
[0035] In addition, if Figure 3As shown, a third guide rail 13 extending along the length direction of the vehicle body is provided on the front floor of the first fixed seat 2, and a support assembly is installed on the third guide rail 13. The support assembly is formed by connecting a front support plate 14 and a rear support plate 15 through a rotating shaft 16. The bottom end of the front support plate 14 is movably mounted on the third guide rail 13, and the bottom end of the rear support plate 15 is fixed on the third guide rail 13. The support assembly is also provided with a horizontal driving mechanism (the horizontal driving mechanism is not shown in the figure) for driving the bottom end of the front support plate 14 to move along the third guide rail 13. When the horizontal driving mechanism drives the bottom end of the front support plate 14 to move backward along the third guide rail 13, the connection between the front support plate 14 and the rear support plate 15 can be gradually raised to finally form a triangular structure. At this time, the top end of the rear support plate 15 abuts against the front lifting bracket to provide support for the front and lower part of the lifting frame 7 or the bottom plate 8 to prevent the lifting frame 7 from tipping over when the car brakes suddenly. The above-mentioned horizontal driving mechanism can be composed of a motor and a driving rod extending along the length direction of the vehicle body. The rotating shaft of the motor and the driving rod are matched through gears and racks. The rotation of the motor drives the driving rod to move horizontally. The end of the driving rod is movably connected to the bottom end of the front support plate 14 through a ring or a limit groove, thereby driving the bottom end of the front support plate 14 to move.
[0036] Of course, the following configuration can also be used to achieve the same function of supporting the lifting frame 7: Figure 4 As shown, a trapezoidal cabinet 17 is provided on the floor in front of the first fixed seat 2, and a rearward-inclined lifting plate 18 and a vertical driving mechanism (the vertical driving mechanism is not shown in the figure) for driving the lifting plate 18 to rise and fall are provided inside the trapezoidal cabinet 17. After the vertical driving mechanism lifts the lifting plate 18, the top of the lifting plate 18 abuts against the front lifting bracket or the front lower part of the bottom plate 8 to provide support for the lifting frame 7. The vertical driving mechanism can be composed of a motor, and the rotating shaft of the motor cooperates with the lifting plate 18 through gears and racks, and the rotation of the motor drives the lifting plate 18 to move vertically. Either of the above two schemes for supporting the lifting frame 7 can be selected.
[0037] like Figure 3As shown, a third fixed seat 19 is provided in front of the second fixed seat 3. In this embodiment, the third fixed seat 19 corresponds to the driver's seat. A fourth vertical guide rail 20 is provided on the backrest of the third fixed seat 19. A leg and foot support box 21 is provided on the fourth guide rail 20. The leg and foot support box 21 is composed of five panels arranged up and down and connected in sequence through horizontal hinges. The top of the top panel is fixedly connected to the backrest of the third fixed seat 19; the bottom panel is movably mounted on the fourth guide rail 20 and connected to the support box driving mechanism. When the support box driving mechanism drives the bottom panel to move upward along the fourth guide rail 20, the five panels can be folded into a box structure with openings at both ends. Passengers on the variable seat 1 can extend their feet into the leg and foot support box 21 to improve comfort and concealment. When the support box driving mechanism drives the bottom panel to move downward along the fourth guide rail 20, the five panels can be flattened into a flat plate close to the back of the backrest of the third fixed seat 19 to reduce the occupied space. The tray driving mechanism is a vertical driving mechanism for transmission, which will not be described in detail here.
[0038] The bottommost plate is installed with a top block 22, the top of which is a plane. The top surface of the top block 22 is against the bottom plate 8 of the leg and foot support box 21 (i.e. the fourth plate from top to bottom), which can form a stable and powerful support to ensure the stability of the leg and foot support box 21.
[0039] like Figure 1 , 4 As shown in Figures 5 and 6, armrest grooves 23 with openings facing the front of the car are provided on both sides of the backrest of the variable seat 1. An armrest 24 is provided in the armrest groove 23. The armrest 24 is composed of two hard plates at the bottom and the top and an elastic strip (such as a rubber strip) connecting the two hard plates. The hard plate at the bottom is movably connected to the backrest of the variable seat 1 through a rotating shaft 27. When the armrest 24 is needed, the armrest 24 can be rotated out of the armrest groove 23. The upper hard plate of the armrest 24 can be folded outward and downward into a right angle under the pressure of the arm to support the passenger's arm and improve comfort. After the passenger moves his arm away, the upper hard plate quickly returns to a state of being closely attached to the bottom hard plate under the elastic force of the elastic strip, so as to be conveniently retracted into the armrest groove 23. By folding the deformable armrest 24, the width of the armrest groove 23 can be reduced, thereby reducing the width occupied by the seat back.
[0040] In this embodiment, in order to improve the degree of automation, the first fixed seat 2 and the second fixed seat 3 are both provided with sensors for detecting whether there is a person sitting on the seat (for example, a pressure sensor arranged at the seat cushion, when the pressure sensor detects that the pressure above the seat cushion exceeds a predetermined range, it indicates that there is a passenger sitting on the seat), and the sensor is connected to a controller 26 arranged on the side of the backrest of the variable seat 1. In this embodiment, the sensor for detecting whether there is a passenger on the first fixed seat 2 is a pressure-controlled switch 25 arranged on the side of the seat cushion of the second fixed seat 3. When the seat cushion of the first fixed seat 2 is folded or removed, the pressure-controlled switch 25 will lose the pressure of the seat cushion of the first fixed seat 2, thereby being triggered.
[0041] The controller 26 is used to control the seat back angle, seat cushion angle, headrest height, rotation support device, lifting frame 7, horizontal drive mechanism, vertical drive mechanism, tray drive mechanism, etc. of the variable seat 1 by remote control or wire control. The controller 26 can detect whether there are people on the first fixed seat 2 and the second fixed seat 3 through sensors, so as to decide to adopt a suitable mode (for example, single mode, double mode, triple mode) to control the action of the variable seat 1 to improve passenger comfort. The specific method is as follows:
[0042] The above-mentioned variable seat 1 can be moved along the first guide rail 6 in the width direction of the vehicle body, so that the space on the side of the seat assembly close to the door is increased, and then the angle of the variable seat 1 is changed by rotating the support device to make it tilted to the center axis of the vehicle body. At this time, the variable seat 1 can be transformed into a reclining chair (such as a reclining chair) by adjusting the backrest angle. Figure 5 As shown in the figure, passengers can stretch their legs, feet, shoulders and backs in the reclining chair, thereby dispersing the pressure of the human body on the legs and back and improving comfort.
[0043] When there is only one passenger in the rear seat, first remove the seat cushion of the first fixed seat 2 or fold it upward (it can also be set to be electrically folded by the controller 26) to expose the first guide rail 6 under the seat cushion of the first fixed seat 2; then move the top plate 10 forward so that the top plate 10 is roughly aligned with the bottom plate 8. At this time, the position of the variable seat 1 has avoided the position of the backrest of the first fixed seat 2, so it can be moved laterally along the first guide rail 6; after the variable seat 1 is moved to the middle or other suitable position, the variable seat 1 can be rotated and the angle of its backrest can be adjusted backward, so that the variable seat 1 is transformed into a reclining chair, and the leg rest 4 and foot rest 5 are extended to support the legs and feet of the passenger. Of course, it is also possible not to use the leg rest 4 and foot rest 5, but to directly place the feet on the seat cushion of the second fixed seat 3; or to extend the feet into the leg and foot rest box 21 at the back of the third fixed seat 19. In order to reduce the space occupied by the variable seat 1 and thus increase the rearward adjustment angle of the seat back, it is best to lower the headrest to the lowest position; at the same time, in order to improve stability, the seat cushion of the variable seat 1 can be adjusted to a high front and low back mode through the lifting frame 7.
[0044] When there are two passengers sitting on the rear seat, respectively, on the variable seat 1 and the second fixed seat 3, firstly, the seat cushion of the first fixed seat 2 is removed or folded upward (it can also be set to be electrically folded by the controller 26) to expose the first guide rail 6 under the seat cushion of the first fixed seat 2; then the top plate 10 is moved forward so that the top plate 10 is roughly aligned with the bottom plate 8. At this time, the position of the variable seat 1 has avoided the position of the backrest of the first fixed seat 2, so it can be moved laterally along the first guide rail 6; different from the above-mentioned single-person mode, it is necessary to control the variable seat 1 to not touch the passenger on the second fixed seat 3 when it is turned into a reclining chair, so the lifting frame 7 must be raised to allow some space between the retractable leg rest 4 and the retractable foot rest 5 and the legs of the passenger on the second fixed seat 3. When the leg and foot rest box 21 at the back of the third fixed seat 19 is used instead of the leg rest 4 and the foot rest 5, the lifting frame 7 must also be raised, and the lifting and lowering of the leg and foot rest box 21 is also restricted. When it is lowered, it must be separated from the legs of the passenger on the second fixed seat 3 by some space.
[0045] When the back row is full of three passengers, the seat cushion of the first fixed seat 2 cannot be moved, and the variable seat 1 can only be simply moved slightly forward and backward, and the posture of the variable seat 1 can be adjusted through the up and down lifting function of the lifting frame 7 and its own seat posture adjustment function to improve comfort.
[0046] In order to ensure safety, the safety belt of the variable seat 1 must be appropriately increased in length so that the safety belt can still function normally when the variable seat 1 is transformed into a reclining chair. When the support assembly and the lifting plate of the trapezoidal cabinet are not used, the safety belt on the first fixed seat 2 can also be inserted under the seat cushion of the variable seat 1 or under the front of the first guide rail 6 (such as Figure 4 As shown), it is also possible to prevent passengers on the variable seat 1 from rolling off the seat when braking, thereby increasing safety.
[0047] From the above description, it can be seen that the variable seat 1 can be set not only on one side of the back row, but also in the middle position of the back row. As long as the position of the variable seat 1 is moved so that the variable seat 1 has enough space to be unfolded into a reclining chair state, it will not be repeated here.
[0048] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific design of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
