[0036] See also Figure 1-3 A car seat cushion frame according to an embodiment of the present invention comprises a seat cushion main frame 1 and a seat cushion flipping device 3, wherein the seat cushion flipping device 3 comprises a driving mechanism 31, an arc-shaped guide mechanism 32 and an arc-shaped moving part 33, wherein the driving mechanism 31 is connected to the front end of the seat cushion main frame 1, the arc-shaped guide mechanism 32 is used to be relatively fixed to the vehicle floor 4, the driving mechanism 31 is connected to the arc-shaped moving part 33, and the driving mechanism 31 is used to drive the arc-shaped moving part 33 to move a set displacement along the arc-shaped guide mechanism 32 to drive the seat cushion main frame 1 to flip forward to a set angle.

[0037] In addition to the backrest frame 2, the automobile seat, for example, the rearmost seat of the automobile, may also include the automobile seat cushion frame provided by the present invention, and the automobile seat cushion frame includes a seat cushion main frame 1 and a seat cushion flipping device 3. As in the prior art, the bottom end of the backrest may be hinged to the rear end of the seat cushion main frame 1 through a recliner, so that the backrest frame 2 may be rotated forward relative to the seat cushion main frame 1 and laid down.

[0038] The differences from the prior art include that a seat cushion flipping device 3 is arranged between the front end of the seat cushion main frame 1 and the vehicle floor 4, the arc guide mechanism 32 of the seat cushion flipping device 3 is relatively fixed to the vehicle floor 4, and the driving mechanism 31 of the seat cushion flipping device 3 is installed at the front end of the seat cushion main frame 1, and the driving mechanism 31 is connected to the arc moving part 33 to drive the arc moving part 33 to move along the arc guide mechanism 32 with an arc trajectory. In this way, the arc moving part 33 moves along the arc guide mechanism 32 to drive the driving mechanism 31 to move, and then the seat cushion main frame 1 connected to the driving mechanism 31 can also move along the arc guide mechanism 32, and the driving mechanism 31 can drive the arc moving part 33 to move along the arc guide mechanism 32 to a set displacement, so that the seat cushion main frame 1 can be flipped forward to a set angle, and when the driving mechanism 31 stops working, the seat cushion main frame 1 is fixed at the set angle.

[0039] On the basis that the seat frame of the rearmost seat has the above functions, when the storage space of the rear luggage box is insufficient, the backrest frame 2 can be first folded forward relative to the seat main frame 1 by the angle adjuster, and then the driving mechanism 31 works to drive the seat main frame 1 and the folded backrest frame 2 to flip forward to a set angle, for example, to flip forward to 90° (such as Figure 7 as shown) or 180° (as shown Fig. 9 As shown), the storage space of the trunk can be greatly increased.

[0040] It can be understood that the “arc-shaped moving member 33 ” does not mean that the structure is in an arc shape as a whole, but means that the structure can move in an arc direction along the arc-shaped guiding mechanism 31 .

[0041] It should be noted that Figure 1-2 and Figure 4 When the seat frame is not in the sitting position, for example, when the seat cushion main frame 1 is horizontally seated on the vehicle floor 4, if the backrest frame 2 is rotated forward and laid down, the upper end of the backrest frame 2 in the original sitting position becomes the "front end", and the lower end of the backrest frame 2 in the original sitting position becomes the "rear end". Figure 7 As shown, when the seat cushion main frame 1 is flipped forward 90°, the rear end of the seat cushion main frame 1 in the original sitting position becomes the "upper end", and the front end of the seat cushion main frame 1 in the original sitting position becomes the "lower end"; Fig. 9 As shown, when the seat cushion main body frame 1 is flipped forward to 180°, the rear end of the seat cushion main body frame 1 in the original sitting state becomes the "front end", and the front end of the seat cushion main body frame 1 in the original sitting state becomes the "rear end".

[0042] In the present invention, unless otherwise specified, the front end and rear end of the seat cushion main frame 1 and the lower end and upper end of the backrest frame 2 all refer to the seat frame in a sitting position (such as Figure 1-2 and Figure 4 The orientation when

[0043] In this embodiment, the seat cushion flipping device 3 can be integrated into the seat cushion frame, that is, the seat cushion flipping device 3 and the seat cushion main body frame 1 can be separately produced in modular form, and then the modular seat cushion flipping device 3 and the seat cushion main body frame 1 are assembled together to form a seat cushion frame. When the seat cushion frame is installed on the vehicle floor 4, it is only necessary to fix the arc-shaped guide mechanism 32 in the seat cushion flipping device 3 relatively to the vehicle floor 4. The modular design of the vehicle seat cushion frame can improve the production efficiency and assembly efficiency, and the seat cushion frame with the seat cushion flipping device 3 can be arranged in different vehicle models, and has high adaptability.

[0044] In this embodiment, see Figure 1 and Figure 7 When the seat cushion flipping device 3 flips the seat cushion main frame 1 and the folded backrest frame 2 forward to 90 degrees, the space below the seat frame in the original sitting state is completely vacant, and the items in the luggage box can be directly stored on the vehicle floor 4 below the seat frame in the original sitting state.

[0045] In this embodiment, see Figure 1 and Fig. 9 When the seat cushion flipping device 3 flips the seat cushion main frame 1 and the folded backrest frame 2 forward to 180°, the space below the seat frame in the original sitting state is completely vacated. Since the seat cushion main frame 1 and the folded backrest frame 2 are flipped forward to 180°, the items in the suitcase can even be stored on the seat cushion after flipping 180°, thereby realizing a larger storage space.

[0046] As mentioned above, the seat cushion frame with the seat cushion flipping device 3 can be the seat cushion frame of the last row of seats. When the last row of seats needs to be flipped forward 180°, the front row seats adjacent to it can be moved forward a certain distance as a whole to ensure that there is enough space in front of the last row of seats in the sitting state to satisfy its forward flipping 180°.

[0047] In addition, when the last row of seats in a sitting position is flipped forward 180°, the backrest of the adjacent front seat can also be rotated forward and folded down. At this time, the seat cushion of the last row of seats and the backrest of the front seat can be used as a bed with various functions.

[0048] See also Figure 3 , Figure 5 and Fig.10Optionally, the arc-shaped guide mechanism 32 includes a first plate body 321, the peripheral side of the first plate body 321 includes an arc segment, the arc segment is provided with a tooth structure 322, the arc-shaped moving part 33 includes a traveling gear 331, the traveling gear 331 is meshed with the tooth structure 322, and the driving mechanism 31 is drivingly connected to the traveling gear 331.

[0049] In this embodiment, Figure 3 , Figure 5 As shown, the thickness direction of the first plate 321 is parallel to the lateral direction of the car (that is, the Y-axis direction), and the peripheral side surface of the first plate 321 includes an arc segment, the axial direction of the arc segment is also parallel to the lateral direction of the car, and accordingly, the axial direction of the tooth structure 322 provided at the arc segment is also parallel to the lateral direction of the car, and the traveling gear 331 is engaged with the tooth structure 322. When the driving mechanism 31 drives the traveling gear 331 to rotate, the rotating traveling gear 331 will make an arc motion along the tooth structure 322, that is, the rotating traveling gear 331 will move around the Y-axis direction, thereby realizing the forward flipping of the seat cushion main frame 1 by the driving mechanism 31.

[0050] On the basis of the meshing of the traveling gear 331 and the tooth structure 322, when the driving mechanism 31 stops working, the traveling gear 331 also moves along the tooth structure 322 for a set displacement and is fixed, so that the seat cushion main frame 1 and the folded backrest frame 2 are flipped forward to a set angle and then stop. For example, the seat cushion main frame 1 and the folded backrest frame 2 can be suspended as shown in FIG. Figure 7 Shown in the 90° position.

[0051] It is understandable that the tooth structure 322 occupies at least half of the entire circumference of the entire arc segment, so that it can be ensured that the seat cushion main frame 1 can flip forward from the 0° position in the sitting state to the 180° position, and can be suspended and fixed at any angle between 0° and 180°.

[0052] See also Figure 3 , Figure 5 and Fig.10 Optionally, an arc-shaped guide groove 323 is provided on the first plate 321, and the seat cushion flipping device 3 also includes a guide column 332, which is connected to the seat cushion main body frame 1 and inserted into the arc-shaped guide groove 323, and the guide column 332 is used to move along the arc-shaped guide groove 323.

[0053] In this embodiment, the extension direction of the arc-shaped guide groove 323 is parallel to the extension direction of the aforementioned arc-shaped segment. On this basis, the seat cushion flipping device 3 also includes a guide column 332, which is relatively fixed to the seat cushion main frame 1, and the guide column 332 is inserted into the arc-shaped guide groove 323. In this way, when the driving mechanism 31 drives the running gear 331 to rotate, under the restriction of the guide column 332 and the arc-shaped guide groove 323, the driving mechanism 31 and the seat cushion main frame 1 can only move around the Y-axis direction to achieve the flipping movement of the seat cushion main frame 1. In addition, through the cooperation between the guide column 332 and the arc-shaped guide groove 323, the stability of the seat cushion main frame 1 during flipping can also be guaranteed.

[0054] The length of the arc-shaped guide groove 323 along its extension direction is at least half of the full circle, so that the cushion body frame 1 can be turned forward from the 0° position in the sitting state to the 180° position, and can be suspended and fixed at any angle between 0° and 180°. Figure 8 and Fig.10 As shown, the arc-shaped guide groove 323 is, for example, half of a full circle. When the guide post 332 is located at one end of the arc-shaped guide groove 323, the seat cushion main body frame 1 is in a sitting state, that is, at 0°. When the guide post 332 moves to the middle of the arc-shaped guide groove 323, the seat cushion main body frame 1 is in a state of flipping forward to 90°. Correspondingly, when the guide post 332 moves to the other end of the arc-shaped guide groove 323, the seat cushion main body frame 1 is in a state of flipping forward to 180°.

[0055] Alternatively, if Figure 1 Shown and Figure 2 As shown, two seat cushion flipping devices 3 are provided, and the two seat cushion flipping devices 3 are respectively arranged at the left and right parts of the front end of the seat cushion main body frame 1, so as to further ensure the flipping stability of the seat cushion main body frame 1.

[0056] See also Figure 3-4 Optionally, the driving mechanism 31 includes a motor 311 and a gear box 312 connected to each other, the output end of the motor 311 is connected to the input end of the gear box 312, and the output end of the gear box 312 is connected to the travel gear 331, wherein the axial direction of the motor 311 is perpendicular to the axial direction of the gear box 312.

[0057] In this embodiment, the driving mechanism 31 includes a motor 311 and a gear transmission box 312. The motor 311 and the gear transmission box 312 can be an integrated structure. The output end of the motor 311 is connected to the input end of the gear transmission box 312, and the output end of the gear transmission box 312 is connected to the traveling gear 331, that is, the motor 311 is connected to the traveling gear 331 through the gear transmission box 312 to drive the traveling gear 331, wherein the gear transmission box 312 can decelerate and increase the torque for the motor 311 to ensure that the driving mechanism 31 has a larger torque to drive the seat cushion main frame 1 and the backrest as a whole to flip.

[0058] Among them, since the traveling gear 331 is meshed with the tooth structure 322, the axial direction of the traveling gear 331 is also parallel to the transverse direction of the car, and the axial direction of the gear transmission box 312 is also parallel to the transverse direction of the car, and the axial direction of the motor 311 is perpendicular to the axial direction of the gear transmission box 312, so that the axial direction of the motor 311 can be parallel to the longitudinal direction of the car.

[0059] It should be noted that, as explained above for the front and rear ends of the seat cushion main frame 1 and the lower and upper ends of the backrest frame 2, the axial direction of the motor 311 is parallel to the longitudinal direction of the car, which also means that when the seat frame is in a sitting position, the axial direction of the motor 311 is parallel to the longitudinal direction of the car. In this way, the drive mechanism 31 will not have a large overlap with the seat cushion main frame 1 in the transverse direction of the car, and the motor 311 and the gear transmission box 312 can reduce the occupation of the transverse space of the car, ensuring that the seat cushion main frame 1 has a larger transverse dimension.

[0060] See also Figure 3 , Figure 5-6 The seat cushion main body frame 1 includes a seat cushion mounting bracket 34. Specifically, the seat cushion mounting bracket 34 includes a seat cushion bracket main board 341 and two side panels 342 respectively bent at both ends of the seat cushion bracket main board 341. At least one of the gear transmission box 312 and the motor 311 is located between the two side panels 342, and at least one of the gear transmission box 312 and the motor 311 is connected to the side panels 342.

[0061] In this embodiment, the seat cushion main frame 1 includes a frame body and a seat cushion mounting bracket 34, and the driving mechanism 31 is specifically fixed to the frame body through the seat cushion mounting bracket 34. Specifically, the seat cushion mounting bracket 34 includes a seat cushion bracket main board 341 and side panels 342 located on the left and right sides of the seat cushion bracket main board 341, wherein a seat cushion support plate 37 can be welded to the frame body first, and the seat cushion bracket main board 341 and the seat cushion support plate 37 only need to be connected and fixed, for example, by bolting; and the side panels 342 on the left and right sides can shield, protect and fix the gear transmission box 312 and / or the motor 311 placed therein, for example Figure 3 and Figure 5 As shown, the gear transmission box 312 is placed between two side plates 342 , and the outer shell of the gear transmission box 312 is connected and fixed to the side plates 342 .

[0062] In addition, in this embodiment, since the axial direction of the gear transmission box 312 is parallel to the lateral direction of the automobile, and the left and right sides of the gear transmission box 312 respectively have side panels 342, a through hole is provided at a side panel 342 corresponding to the output end of the gear transmission box 312, and the axle of the traveling gear 331 can be connected to the output end of the gear transmission box 312 through the through hole.

[0063] Optionally, the travel gear 331 is rotatably connected to the cushion main frame 1. In this way, since the end of the travel gear 331 axially away from the driving mechanism 31 is rotatably connected to the cushion main frame 1, the cushion main frame 1 provides support for the travel gear 331, thereby improving the stability of the self-rotation and arc motion of the travel gear 331.

[0064] See also Figure 3 Optionally, as mentioned above, the seat cushion main frame 1 includes a seat cushion mounting bracket 34, and in addition, it also includes an intermediate bracket 35, the intermediate bracket 35 includes a main body and a plurality of interconnected ends 351 arranged along the circumference of the main body, one of the connecting ends 351 is connected to the seat cushion mounting bracket 34 through the guide column 332, and the other connecting ends 351 are connected to the seat cushion mounting bracket 34 through fasteners, and the first plate 321 and the traveling gear 331 are respectively located between the intermediate bracket 35 and the seat cushion mounting bracket 34, and the traveling gear 331 is rotatably connected to the main body of the intermediate bracket 35.

[0065] In this embodiment, the intermediate bracket 35 includes a plurality of connection ends 351 arranged along the circumferential direction. For example, as shown in Figure 3, the intermediate bracket 35 includes three connection ends 351. The intermediate bracket 35 with three connection ends 351 is an overall Y-shaped bracket structure, wherein two connection ends 351 are connected and fixed to the seat cushion mounting bracket 34, and the other connection end 351 is connected and fixed to the seat cushion mounting bracket 34 through the guide column 332. The setting of the intermediate bracket 35 can ensure that the movement of the guide column 332 is more stable, and because the first plate body 321 is located between the intermediate bracket 35 and the seat cushion mounting bracket 34, it is also ensured that the guide column 332 will not move out of the arc guide groove 323, and it is also ensured that the seat cushion main body frame 1 will not move in the left and right directions when it is flipped. In addition, since the traveling gear 331 is also located between the intermediate bracket 35 and the mounting bracket 3, the end of the traveling gear 331 axially away from the driving mechanism 31 can be specifically rotatably connected to the main body of the intermediate bracket 35 to provide support for the traveling gear 331 through the intermediate bracket 35, thereby improving the stability of the self-rotation and arc motion of the traveling gear 331.

[0066] Specifically, see Figure 3 One of the connection ends 351 is connected to the corresponding side panel 342 in the seat cushion mounting bracket 34 through the guide column 332, and the other connection end 351 is connected to the side panel 342 through a fastener, and the first plate body 321 and the traveling gear 331 are specifically located between the intermediate bracket 35 and the side panel 342.

[0067] See also Figure 1 and Figure 3 Optionally, the car seat frame is a seat cushion frame of a rear seat, the vehicle floor 4 includes a rear floor 41 and a front floor 42, the rear floor 41 is higher than the front floor 42, and the rear floor 41 and the front floor 42 are connected by a transition floor 43; the seat cushion flipping device 3 also includes a floor bracket 36, the bottom end of the floor bracket 36 is connected to the transition floor 43, and the arc guide mechanism 32 is installed on the top end of the floor bracket 36.

[0068] In this embodiment, the seat cushion frame of the automobile is the seat cushion frame of the rear seat (for example, the seat cushion frame of the last row of seats), so when the seat cushion main body frame 1 is in a sitting state, the seat cushion main body frame 1 is located above the rear floor 41 of the vehicle floor 4. It should be noted that, usually in a car, the vehicle floor 4 includes a front floor 42 and a rear floor 41, and the rear floor 41 is higher than the front floor 42. The rear floor 41 and the front floor 42 are connected by an inclined transition floor 43, which can improve the structural strength and rigidity of the rear floor 41 to better withstand the force generated in a collision and protect passengers and luggage compartments; and for rear-wheel drive models, the rear axle and related drive system components usually occupy a certain space, and the rear floor 41 is designed to be higher, and there is enough space below it to accommodate these components.

[0069] On this basis, the first plate body 321 is connected to the transition floor 43 through the floor bracket 36, that is, after the first plate body 321 is connected and fixed to the floor bracket 36, the floor bracket 36 is connected and fixed to the transition floor 43. In this way, the installation of the seat cushion flipping device 3 will not occupy the space above the front floor 42, nor will it occupy the space on the rear floor 41, so as to ensure that there is enough longitudinal space on the rear floor 41 to place the seat cushion main body frame 1 in the sitting state, and also to ensure that the occupant has enough space to move on the front floor 42 in the sitting state.

[0070] Among them, since the first plate body 321 is connected to the transition floor 43 through the floor bracket 36, the floor bracket 36 can ensure that there is a certain distance between the first plate body 321 and the vehicle floor 4, and further, when the seat cushion main frame 1 is flipped forward 180°, the seat cushion mounting bracket 34, the driving mechanism 31, and the running gear 331 will not interfere with the vehicle floor 4, so as to ensure that the seat cushion main frame 1 can be flipped forward 180°. In addition, since the front floor 42 is lower than the rear floor 41, when the seat cushion main frame 1 and the folded backrest frame 2 are flipped forward to 180° together, the backrest frame 2 will not interfere with the lower front floor 42, that is, there is enough space above the lower front floor 42 to accommodate the backrest frame 2, so as to ensure that the seat cushion main frame 1 and the folded backrest frame 2 can be flipped forward to 180° together.

[0071] Optionally, the floor bracket 36 includes a first bracket plate and a second bracket plate that are perpendicular and integrally formed, which can improve the rigidity and strength of the floor bracket 36, wherein the first bracket plate is attached to and connected to the transition floor 43, and the second bracket plate is attached to and connected to the first plate body 321.

[0072] It should be noted that, in other embodiments, the seat cushion frame of the car can also be the seat cushion frame of the non-last row seat, that is, the seat cushion flipping device 3 can also be arranged in the non-last row seat to drive the non-last row seat to flip forward to a set angle. For example, in a car with three rows of seats, the seat cushion flipping device can be arranged in the second row seat in addition to the last row seat (i.e., the third row seat); it can be understood that compared with the first row seat, the second row seat and the third row seat are both rear seats.

[0073] See also Figure 1-5 Optionally, at least part of the driving mechanism 31 is located between the two lateral ends of the seat cushion main body frame 1; or / and, the set angle is 90° or 180°.

[0074] In this embodiment, at least part of the driving mechanism 31 is located between the two lateral ends of the seat cushion main frame 1, so as to improve the integration of the seat cushion flipping device 3 and the seat cushion main frame 1 in the lateral direction, so that the seat cushion main frame 1 can occupy as much lateral space as possible inside the vehicle body, and ensure that the width of the seat cushion is large enough. For example, the driving mechanism 31 and the arc-shaped moving part 33 can both be located between the two lateral ends of the seat cushion main frame 1.

[0075] In addition, since the first plate 321 and the floor bracket 36 are fixed during the flipping of the seat cushion main body frame 1, the first plate 321 and the second bracket plate of the floor bracket 36 can be located on the outside of the seat cushion main body frame 1 in the transverse direction, that is, the first plate 321 and the second bracket plate can be located between the seat cushion main body frame 1 and the vehicle body side panel 342 to ensure that the lateral end of the seat cushion main body frame 1 will not be interfered by the first plate 321 and the second bracket plate during the flipping of the seat cushion main body frame 1 forward to 180°.

[0076] Another embodiment of the present invention provides a car seat, comprising a backrest frame and the above-mentioned car seat cushion frame, wherein the backrest frame is connected to the rear end of a seat cushion body frame of the car seat cushion frame via a recliner.
