Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a seat cushion device, a seat, and a vehicle. Background Technology

[0002] Currently, vehicles have become an important means of transportation in people's daily lives and work, and people's requirements for vehicle performance and comfort are constantly increasing. When there are two or more rows of seats in the passenger compartment, the usable space of each row is limited. In related technologies, manufacturers have designed the middle row seats or rear seats to have a sliding structure in order to expand the usable space of the seats, but the above-mentioned seat arrangement still has a low utilization rate of the passenger compartment space. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a seat cushion device, wherein the seat cushion frame of the seat cushion device can be flipped upward, thereby reserving more usable space for the front seat to slide forward and backward, and the seat cushion frame has high stability when flipped.

[0005] An embodiment of this utility model also proposes a seat.

[0006] An embodiment of this utility model also proposes a vehicle.

[0007] The seat cushion device of this utility model includes: a fixed seat for mounting on a vehicle floor; a seat cushion frame, the rear end of which is rotatable relative to the fixed seat about a first axis; and at least two drive mechanisms, the at least two drive mechanisms being arranged at intervals along the left and right directions of the fixed seat, the drive mechanisms being connected to the fixed seat and the seat cushion frame, and the drive mechanisms being able to drive the seat cushion frame to flip upward about the first axis.

[0008] According to an embodiment of the present invention, the seat cushion device has a rotatable rear end frame relative to the fixed seat around a first axis. When the seat cushion device is not in use, the drive mechanism can flip the seat cushion frame upwards around the first axis. This reduces the space occupied by the seat cushion frame in the front-rear direction, thus reserving more usable space for the front-row seats to slide forward and backward, which is beneficial to improving the space utilization rate in the passenger compartment. Furthermore, since there are at least two drive mechanisms arranged at intervals along the left-right direction of the fixed seat, the seat cushion frame flips more smoothly, with greater driving force and higher stability.

[0009] In some embodiments, the seat cushion frame includes a frame body and an adapter bracket. The adapter bracket is connected to the frame body and has a first connecting portion and a second connecting portion. The first connecting portion is rotatably connected to the fixed seat about the first axis, and the second connecting portion is rotatably connected to the drive mechanism. The length of the drive mechanism is adjustable to drive the frame body to flip about the first axis.

[0010] In some embodiments, the adapter bracket is detachably connected to the frame body.

[0011] In some embodiments, the fixed base includes a crossbeam and two side plates, the two side plates being arranged on both sides of the crossbeam along the left-right direction, the two drive mechanisms being respectively disposed on the two side plates, and the first connecting portion being rotatably connected to the side plates.

[0012] In some embodiments, the side plate is provided with a clearance hole, and the second connecting portion is located within the outer periphery of the clearance hole in a projection orthogonal to the left and right directions.

[0013] In some embodiments, the seat cushion frame has a first connecting portion and a second connecting portion. The first connecting portion is rotatably connected to the fixed seat about the first axis. The driving mechanism includes a drive motor and a transmission rod. The drive motor is disposed on the fixed seat and connected to the transmission rod. One end of the transmission rod is rotatably connected to the second connecting portion. The drive motor can drive the transmission rod to extend or retract.

[0014] In some embodiments, the seat frame has a first connecting portion and a second connecting portion, the first connecting portion being rotatably connected to the fixed seat about the first axis, and the driving mechanism further includes a gas strut, one end of which is rotatably connected to the fixed seat, and the other end of which is rotatably connected to the second connecting portion.

[0015] In some embodiments, the seat cushion frame has multiple seating areas, which are arranged sequentially along the left-right direction of the seat cushion frame.

[0016] In some embodiments, the seat cushion device further includes a locking mechanism disposed at the front end of the seat cushion frame. The locking mechanism is movable between a locked position and a released position. In the locked position, the locking mechanism is connected to the seat cushion frame and the fixed seat to restrict the seat cushion frame from rotating relative to the fixed seat. In the released position, the driving mechanism can drive the seat cushion frame to rotate relative to the fixed seat.

[0017] In some embodiments, the locking mechanism is located in the middle of the seat cushion frame along the left-right direction.

[0018] In some embodiments, the locking mechanism includes a lock body and a lock hook. The lock body is located at the front end of the seat cushion frame, and the lock hook is located on the fixed base. The lock body has a locking tongue. In the locked position, the locking tongue engages with the lock hook, and in the released position, the locking tongue separates from the lock hook.

[0019] In some embodiments, the locking mechanism further includes a traction member, one end of which is connected to the latch, and the traction member can drive the latch to move between the locked position and the released position.

[0020] In some embodiments, the locking mechanism further includes an electrically controlled button, which is electrically connected to the bolt and is used to control the movement of the bolt between the locked position and the released position.

[0021] Another embodiment of the present invention provides a seat comprising: a seat cushion device, wherein the seat cushion device is any one of the seat cushion devices described in the embodiments of the present invention; and a backrest frame, wherein the backrest frame is connected to the fixed seat.

[0022] According to an embodiment of the present invention, the seat cushion frame is rotatable relative to the fixed seat around a first axis. When the seat cushion is not in use, the drive mechanism can flip the seat cushion frame upwards around the first axis. This reduces the space occupied by the seat cushion frame in the front-rear direction, thus reserving more space for the front-row seats to slide forward and backward, which is beneficial to improving the space utilization rate in the passenger compartment. Furthermore, since there are at least two drive mechanisms, and they are spaced apart along the left and right directions of the fixed seat, the seat cushion frame flips more smoothly, with greater driving force and higher stability.

[0023] Another embodiment of the vehicle of the present invention includes the seat cushion device described in any one embodiment of the present invention or the seat described in the embodiments of the present invention.

[0024] In the vehicle according to an embodiment of this utility model, since the rear end of the seat cushion frame is rotatable relative to the fixed seat around a first axis, when the seat cushion is not occupied, the drive mechanism can flip the seat cushion frame upward around the first axis. This reduces the space occupied by the seat cushion frame in the front-rear direction, thereby reserving more usable space for the front-seat sliding and improving the space utilization rate in the passenger compartment. Furthermore, since there are at least two drive mechanisms arranged at intervals along the left-right direction of the fixed seat, the seat cushion frame flips more smoothly, with greater driving force and higher stability.

[0025] In some embodiments, the vehicle further includes a vehicle floor, the mounting bracket being connected to the vehicle floor, and the mounting bracket being adjustable in position relative to the vehicle floor in its longitudinal direction. Attached Figure Description

[0038] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following is a reference appendix. Figures 1 to 10 This invention describes a seat cushion device, a seat, and a vehicle according to embodiments of the present invention.

[0040] like Figures 1 to 8 As shown, the seat cushion device of this utility model embodiment includes: a fixed base 1, a seat cushion frame 2, and at least two drive mechanisms 3. The fixed base 1 is used to install on the vehicle floor, and the rear end of the seat cushion frame 2 is rotatable relative to the fixed base 1 about a first axis. At least two drive mechanisms 3 are arranged at intervals along the left and right directions of the fixed base 1. The drive mechanisms 3 are connected to the fixed base 1 and the seat cushion frame 2, and the drive mechanisms 3 can drive the seat cushion frame 2 to flip upward about the first axis.

[0041] Understandably, the first axis is roughly parallel to the left-right direction of the seat cushion frame 2. When the drive mechanism 3 drives the seat cushion frame 2 to flip upward, the front end of the seat cushion frame 2 will gradually rotate towards the backrest, so that the seat cushion frame 2 folds backward.

[0042] According to the embodiment of the present invention, the seat cushion device has a rear end that is rotatable relative to the fixed seat 1 around a first axis. When the seat cushion device is not in use, the drive mechanism 3 can flip the seat cushion frame 2 upward around the first axis. This reduces the space occupied by the seat cushion frame 2 in the front-rear direction, thus reserving more usable space for the front-row seats to slide forward and backward, which is beneficial to improving the space utilization rate in the passenger compartment. Furthermore, since there are at least two drive mechanisms 3, and they are arranged at intervals along the left and right directions of the fixed seat 1, the seat cushion frame 2 flips more smoothly, with greater driving force and higher stability.

[0043] like Figure 1 As shown, there can be two or more drive mechanisms 3. In the example of this utility model, there are two drive mechanisms 3.

[0044] Since there are at least two drive mechanisms 3, and the two drive mechanisms 3 are arranged at intervals along the left and right directions of the fixed seat 1, compared with the seat cushion device that only arranges the drive mechanism 3 on one side, the seat cushion frame 2 of the seat cushion device in this utility model embodiment has better synchronization when flipping left and right, is not easy to shake, and is conducive to improving the structural rigidity of the seat cushion device and the stability of the seat cushion frame 2 when flipping.

[0045] Optionally, such as Figure 1As shown, the seat cushion frame 2 has multiple seating areas (not shown), which are arranged sequentially along the left-right direction of the seat cushion frame 2. In other words, the seat cushion device of this embodiment can be applied to row seats, meaning that multiple people can sit on the seat cushion device. This allows for a higher degree of integration in the seat cushion device, and the two drive mechanisms 3 on the left and right sides can provide greater power to the seat cushion frame 2, resulting in greater stability when the seat cushion frame 2 is flipped.

[0046] For example, the seating area can be two or three, that is, the seat frame 2 can accommodate two or three people side by side.

[0047] Optionally, such as Figure 2 , Figure 5 and Figure 6 As shown, the seat frame 2 includes a frame body 21 and a connecting bracket 22. The connecting bracket 22 is connected to the frame body 21. The connecting bracket 22 has a first connecting part 221 and a second connecting part 222. The first connecting part 221 is rotatably connected to the fixed seat 1 around a first axis. The second connecting part 222 is rotatably connected to the drive mechanism 3. The length of the drive mechanism 3 is adjustable to drive the frame body 21 to flip around the first axis.

[0048] It is understandable that, such as Figure 6 As shown, the first connecting part 221 and the second connecting part 222 are arranged at intervals on the adapter bracket 22. When the drive mechanism 3 extends, it can drive the adapter bracket 22 to rotate counterclockwise around the first axis, thereby causing the seat cushion frame 2 to flip upward. When the drive mechanism 3 shortens, it can drive the adapter bracket 22 to rotate clockwise around the first axis, thereby causing the seat cushion frame 2 to flip downward.

[0049] The seat cushion device of this utility model, by designing the seat cushion frame 2 as a combination structure of "frame body 21 and adapter bracket 22", facilitates the processing and manufacturing of the seat cushion frame 2 and the assembly of the seat cushion device. Furthermore, the drive mechanism 3 drives the front end of the frame body 21 to flip upwards around the first axis through length adjustment, which simplifies the structural design of the drive mechanism 3, ensures reliable operation, and facilitates its integration into the seat cushion device, preventing interference between the drive mechanism 3 and surrounding components of the seat cushion device.

[0050] For example, such as Figure 4 and Figure 5As shown, the adapter bracket 22 is detachably connected to the frame body 21. This facilitates the assembly of the seat cushion device. It can be understood that when assembling the seat cushion frame 2, the adapter bracket 22 can be connected to the fixed base 1 and the drive mechanism 3 first, and then the frame body 21 can be assembled onto the adapter bracket 22. Compared to a solution where the adapter bracket 22 and the frame body 21 are integrally molded, this makes the assembly of the seat cushion frame 2 more convenient and improves assembly efficiency.

[0051] like Figure 1 As shown, there are two adapter brackets 22, which are respectively arranged on the left and right sides of the frame body 21. One adapter bracket 22 is connected to one drive mechanism 3, and the other adapter bracket 22 is connected to another drive mechanism 3.

[0052] For example, the adapter bracket 22 and the frame body 21 are connected by multiple threaded parts.

[0053] like Figure 5 and Figure 8 As shown, the adapter bracket 22 includes a first bracket 223 and a second bracket 224 connected together. The first bracket 223 and the second bracket 224 can be connected by welding or by fastening with threaded parts. The first connecting part 221 and the second connecting part 222 are both provided on the first bracket 223. The second bracket 224 is provided with a plurality of mounting holes 2241, which correspond one-to-one with a plurality of mating holes (not shown) on the frame body 21. Threaded parts are passed through the mounting holes 2241 and the mating holes, thereby fixing the adapter bracket 22 and the frame body 21.

[0054] Optionally, such as Figures 1 to 3 As shown, the fixing base 1 includes a crossbeam 12 and two side plates 11, which are arranged on both sides of the crossbeam 12 in the left-right direction. It can be understood that the crossbeam 12 extends in the left-right direction and is located between the two side plates 11, thereby improving the structural stability of the fixing base 1.

[0055] like Figures 1 to 3 As shown, two drive mechanisms 3 are respectively mounted on two side plates 11, and the first connecting part 221 is rotatably connected to the side plate 11. Since the two drive mechanisms 3 are connected to the two side plates 11 in a one-to-one correspondence, the side plates 11 can fix the drive mechanisms 3 in place, and also facilitate the concealment of the drive mechanisms 3. It is understood that a decorative panel (not shown) is provided above the side plate 11. Since the drive mechanisms 3 are connected to the side plates 11, the decorative panel can also cover the drive mechanisms 3, thereby improving the overall appearance and aesthetics of the seat cushion device.

[0056] like Figure 6As shown, the side plate 11 is provided with a clearance hole 111. In the projection orthogonal to the left and right directions, the second connecting part 222 is located within the outer periphery of the clearance hole 111. It can be understood that the clearance hole 111 can expose the pivot position of the second connecting part 222 and the drive mechanism 3 from the left and right sides of the seat device, so that the operator can observe the pivot position of the second connecting part 222 and the drive mechanism 3, so that the operator can insert the pin into the second connecting part 222 and the drive mechanism 3, thereby improving the convenience of assembling the seat device.

[0057] Optionally, such as Figure 7 and Figure 8 As shown, the seat frame 2 has a first connecting part 221 and a second connecting part 222. The first connecting part 221 is rotatably connected to the fixed base 1 around a first axis. The driving mechanism 3 includes a drive motor 31 and a transmission rod 32. The drive motor 31 is located on the fixed base 1 and connected to the transmission rod 32. One end of the transmission rod 32 is rotatably connected to the second connecting part 222. The drive motor 31 can drive the transmission rod 32 to extend or retract. It can be understood that the drive motor 31 can drive the transmission rod 32 to extend or retract, so that the adapter bracket 22 rotates relative to the fixed base 1, thereby causing the frame body 21 to flip up or down.

[0058] The seat cushion device of this utility model adopts the above-described structure for the drive mechanism 3, enabling the seat cushion frame 2 to automatically flip up or down without manual operation by the user. This improves the overall intelligence of the vehicle and enhances the user experience.

[0059] The transmission rod 32 can be a threaded screw, a worm gear, or a rack and pinion.

[0060] For example, when the transmission rod 32 is a threaded screw, the threaded screw and the threaded sleeve are engaged, and the drive motor 31 can drive the threaded sleeve to rotate, and the threaded sleeve can drive the threaded screw to translate.

[0061] For example, when the transmission rod 32 is a worm, the worm and the worm wheel cooperate, and the drive motor 31 can rotate through the worm wheel, which can drive the threaded screw to move.

[0062] For example, when the transmission rod 32 is a rack and pinion, the rack and pinion mesh with a gear, and the drive motor 31 can rotate through the gear, which can drive the rack and pinion to move horizontally.

[0063] Optionally, such as Figures 3 to 5 As shown, the seat frame 2 has a first connecting part 221 and a second connecting part 222. The first connecting part 221 is rotatably connected to the fixed seat 1 around a first axis. The drive mechanism 3 also includes a gas strut 33. One end of the gas strut 33 is rotatably connected to the fixed seat 1, and the other end of the gas strut 33 is rotatably connected to the second connecting part 222.

[0064] Understandably, the gas strut 33 is also known as a gas spring. When the seat cushion frame 2 is unlocked, the gas strut 33 can extend under the action of internal air pressure, thereby allowing the adapter bracket 22 to rotate relative to the fixed seat 1, which in turn causes the frame body 21 to flip upward. When the user needs to flip the seat cushion frame 2 to a horizontal position (i.e., the seat cushion frame 2 returns to the sitting position), the user can manually press down on the seat cushion frame 2 to compress the gas strut 33, shortening its length, and finally locking the seat cushion frame 2 to prevent the gas strut 33 from lifting the seat cushion frame 2.

[0065] The seat cushion device of this utility model can reduce the production cost of the seat cushion device by adopting the above structure for the drive mechanism 3, and the structural design is simple and the subsequent maintenance cost is low.

[0066] like Figure 1 As shown, the two drive mechanisms 3 are arranged symmetrically from left to right, and the thrust generated by the two drive mechanisms 3 is roughly the same.

[0067] Optionally, such as Figure 1 and Figure 9 As shown, the seat cushion device also includes a locking mechanism 4, which is located at the front end of the seat cushion frame 2. The locking mechanism 4 is movable between a locked position and a released position. In the locked position, the locking mechanism 4 is connected to the seat cushion frame 2 and the fixed seat 1 to restrict the seat cushion frame 2 from rotating relative to the fixed seat 1. In the released position, the drive mechanism 3 can drive the seat cushion frame 2 to rotate relative to the fixed seat 1.

[0068] When the user needs to keep the seat cushion frame 2 in a seated position, the locking mechanism 4 can lock the seat cushion frame 2 to the fixed seat 1 to restrict the seat cushion frame 2 from rotating relative to the fixed seat 1. Compared with the solution where "the locking mechanism 4 is located at the rear end of the seat cushion frame 2", since the locking mechanism 4 of this application is located at the front end of the seat cushion frame 2, when the seat cushion frame 2 is folded up, the locking mechanism 4 will not move to the bottom of the seat cushion frame 2. Therefore, the locking mechanism 4 of the folded seat cushion device will not occupy the bottom space of the seat cushion frame 2, which helps to reduce the gap between the folded seat cushion frame 2 and the vehicle floor, thereby improving the space utilization rate in the passenger compartment.

[0069] Optionally, such as Figure 1 As shown, the locking mechanism 4 is located in the middle of the seat cushion frame 2 along the left-right direction. It can be understood that the locking mechanism 4 is located in the middle of the two side plates 11, which can ensure that the locking force on the left and right sides of the seat cushion frame 2 is equal, so that the deformation and rigidity gap on the left and right sides of the seat cushion frame 2 are consistent.

[0070] Optionally, such as Figure 9As shown, the locking mechanism 4 includes a lock body 41 and a lock hook 42. The lock body 41 is located at the front end of the seat cushion frame 2, and the lock hook 42 is located on the crossbeam 12 of the fixed base 1. The lock body 41 has a locking tongue 411. In the locked position, the locking tongue 411 engages with the lock hook 42, and in the released position, the locking tongue 411 separates from the lock hook 42. By configuring the locking mechanism 4 with the above-described structure, the seat cushion device of this embodiment of the present invention can simplify the structural design of the locking mechanism 4 and facilitate its processing and manufacturing.

[0071] In one example, such as Figure 9 As shown, the locking mechanism 4 also includes a traction member 43. One end of the traction member 43 is connected to the latch 411, and the other end of the traction member 43 has a pulling part. The traction member 43 can drive the latch 411 to move between the locked position and the released position. It can be understood that when the user needs to unlock the locking mechanism 4, he can pull the traction member 43 to separate the latch 411 from the lock hook 42. A return spring (not shown) is provided inside the lock body 41. When the pulling force of the traction member 43 disappears, the latch 411 can return to the locked position under the elastic force of the return spring.

[0072] The seat cushion device of this utility model can reduce the production cost of the locking mechanism 4 by unlocking it in the above manner, and it is not easily damaged and has high reliability.

[0073] For example, the traction element 43 can be a pull strap or a buckle.

[0074] In another example, the locking mechanism 4 also includes an electrically controlled button (not shown), which is electrically connected to the locking tongue 411 and is used to control the movement of the locking tongue 411 between the locked position and the released position. By designing the locking mechanism 4 to be electrically controlled, the seat cushion device of this embodiment of the invention can improve the intelligence level of the locking mechanism 4 during unlocking, thus enhancing the user experience.

[0075] like Figure 10 As shown, another embodiment of the seat of the present invention includes: a seat cushion device and a backrest frame 5. The seat cushion device is the seat cushion device of the present invention, and the backrest frame 5 is connected to the fixed seat 1.

[0076] According to an embodiment of the present invention, the seat cushion frame 2 is rotatable relative to the fixed seat 1 around a first axis. When the seat cushion is not in use, the drive mechanism 3 can flip the seat cushion frame 2 upwards around the first axis, thereby reducing the space occupied by the seat cushion frame 2 in the front-to-back direction and reserving more space for the front seat to slide forward and backward. Furthermore, since there are at least two drive mechanisms 3, and they are spaced apart along the left and right directions of the fixed seat 1, the flipping of the seat cushion frame 2 is more stable, with greater driving force and higher stability.

[0077] Another embodiment of the vehicle of the present invention includes the seat cushion device of the present invention or the seat of the present invention.

[0078] In the vehicle according to an embodiment of this utility model, since the rear end of the seat cushion frame 2 is rotatable relative to the fixed seat 1 around a first axis, when the seat cushion is not occupied, the drive mechanism 3 can flip the seat cushion frame 2 upward around the first axis. This reduces the space occupied by the seat cushion frame 2 in the front-rear direction, thereby reserving more usable space for the front-row seats to slide forward and backward. Furthermore, since there are at least two drive mechanisms 3, and they are spaced apart along the left and right directions of the fixed seat 1, the flipping of the seat cushion frame 2 is more stable, with greater driving force and higher stability.

[0079] Optionally, the vehicle also includes a vehicle floor (not shown), with a mounting bracket connected to the vehicle floor. The mounting bracket 1 is adjustable in position relative to the vehicle floor in its fore-and-aft direction. It is understood that the seat cushion device can slide in the fore-and-aft direction of the vehicle to adjust the fore-and-aft distance between the seat cushion device and the front seats. Because the seat cushion device is adjustable in position in the fore-and-aft direction of the vehicle, the space inside the passenger compartment can be further optimized, allowing users to adjust the seat position according to actual needs and improving the user experience.
