Description

Technical Field

[0001] This application relates to the field of seating technology, specifically to a seat and an automobile. Background Technology

[0002] Currently, some car seats have a reclining function, meaning the backrest can rotate relative to the seat cushion and be placed in a near-horizontal position. However, to ensure the backrest can recline properly, its rotation center line is usually higher than the seat cushion support plane. This results in a significant height difference between the seat cushion support plane and the backrest support plane after the backrest is reclined. This height difference leads to a lack of support for the user's buttocks, or even a noticeable unsupported position, resulting in a poor comfort experience when lying flat. Utility Model Content

[0003] This application provides a seat and an automobile, which aim to solve the above-mentioned technical problems.

[0004] In a first aspect, this application provides a seat, comprising: A seat frame, wherein a rear crossbeam of the seat frame is mounted on the seat frame; A lifting assembly, which is rotatably mounted on the seat cushion frame; A drive assembly for driving the lifting assembly to rotate relative to the seat cushion frame; The lifting component, driven by the driving component, has a first rotational position and a second rotational position. When the lifting assembly is in the first rotational position, the portion of the lifting assembly adjacent to the rear crossbeam of the seat frame is raised; when the lifting assembly is in the second rotational position, the portion of the lifting assembly adjacent to the rear crossbeam of the seat frame is lowered.

[0005] In some embodiments, the seat cushion frame includes a first side wing support and a second side wing support; The rear crossbeam of the seat frame is mounted across the first side wing bracket and the second side wing bracket.

[0006] In some embodiments, the lifting assembly includes a lifting rod having a first side wing, a second side wing, and a crossbar; The first side wing rod is parallel to the first side wing support, the second side wing rod is parallel to the second side wing support, and the crossbar is parallel to the rear crossbeam of the seat frame.

[0007] In some embodiments, the lifting assembly further includes a drive plate rotatably mounted on the seat cushion frame; The lifting rod is fixed to the drive plate, and the drive plate has a gear section.

[0008] In some embodiments, the drive plate is rotatably fixed to the first side wing bracket, the first side wing rod is connected to the drive plate, and the second side wing rod is rotatably fixed to the second side wing bracket, wherein: The connection point between the first side wing rod and the drive plate is located on the side of the drive plate's rotation axis away from the gear section; Alternatively, the connection point between the first side wing rod and the drive plate is located between the rotation axis of the drive plate and the gear section.

[0009] In some embodiments, the drive plate has a rotating shaft hole and a limiting groove; A limiting rod is installed in the limiting groove, and the limiting rod is fixed to the seat cushion frame.

[0010] In some embodiments, when the lifting assembly is in the first rotational position, the limiting rod contacts the inner wall surface of one end of the limiting groove; When the lifting assembly is in the second rotation position, the limiting rod contacts the inner wall surface of the other end of the limiting groove; And / or, the limiting groove is arranged in an arc shape with the center of the rotating shaft hole as the center.

[0011] In some embodiments, the drive assembly includes a drive gear and a drive motor; The drive gear meshes with the gear section, and the drive motor is used to drive the drive gear to rotate.

[0012] In some embodiments, the drive motor is fixed to the side of the first side wing bracket opposite to the second side wing bracket.

[0013] In a second aspect, this application provides an automobile, characterized in that it includes a seat as described in the first aspect.

[0014] Secondly, this application provides an automobile including a seat as described in the first aspect.

[0015] In this embodiment, the lifting component has a first rotational position and a second rotational position under the drive of the driving component. When the lifting component is in the first rotational position, the part of the lifting component adjacent to the rear crossbeam of the seat frame is raised. Then, the part of the lifting component adjacent to the rear crossbeam of the seat frame can lift the seat cushion foam on the seat cushion frame. That is, at this time, the part of the seat cushion foam adjacent to the rear crossbeam of the seat frame is lifted by the lifting component. Therefore, the height difference between the seat cushion support plane and the back support plane can be reduced after the seat back is flattened. This can provide support for the rear of the user's buttocks and avoid a significant unsupported state, ultimately improving the user's comfort experience when lying flat.

[0021] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0022] This application provides a seat and a car, which will be described in detail below.

[0023] First, refer to Figure 1 , Figure 1 A schematic diagram of a seat in an embodiment of this application is shown, wherein the seat includes a seat cushion frame 10, a lifting component 30, and a drive component 40.

[0024] Specifically, the seat cushion frame 10 provides rigid support for the seat cushion portion. Generally, the seat cushion frame 10 can accommodate seat cushion foam and fabric covering to provide flexible support for the user's buttocks, thereby improving the user's riding experience. Simultaneously, the seat cushion frame 10 is equipped with a rear crossbeam 20, which can accommodate the seat back (e.g., a backrest frame and backrest foam, not shown in the figure), allowing the seat back to rotate relative to the seat cushion frame 10 to achieve a flattened position.

[0025] The lifting component 30 is rotatably mounted on the seat frame 10. The drive component 40 is used to drive the lifting component 30 to rotate relative to the seat frame 10, so that the lifting component 30 can lift the seat foam on the seat frame 10 during rotation, or can retract into the seat frame 10 during rotation and avoid lifting the seat foam so as not to make the user feel a foreign object.

[0026] For example, the lifting component 30 may include one or more rod-shaped or plate-shaped rotating parts, and the driving component 40 may include a driving mechanism such as a motor, hydraulic or pneumatic telescopic rod. Those skilled in the art can make adjustments according to actual needs, and this application does not make specific limitations.

[0027] In this embodiment, the lifting component 30 has a first rotational position and a second rotational position driven by the driving component 40. When the lifting component 30 is in the first rotational position, the portion of the lifting component 30 adjacent to the rear crossbeam 20 of the seat frame is raised. This portion of the lifting component 30 adjacent to the rear crossbeam 20 of the seat frame can lift the seat cushion foam on the seat cushion frame 10. That is, at this time, the portion of the seat cushion foam adjacent to the rear crossbeam 20 of the seat frame is lifted by the lifting component 30. Therefore, after the seat back is flattened, the height difference between the seat cushion support plane and the backrest support plane is reduced, thereby providing support for the user's buttocks and avoiding a significant unsupported state, ultimately improving the user's comfort experience when lying down. When the lifting component 30 is in the second rotational position, the portion of the lifting component 30 adjacent to the rear crossbeam 20 of the seat frame is lowered. The lifting component 30 can retract into the seat cushion frame 10 and avoid lifting the seat cushion foam, which would cause the user to feel a foreign object sensation.

[0028] In some embodiments of this application, see Figure 1 The seat frame 10 includes a first side wing support 11 and a second side wing support 12. The rear crossbeam 20 of the seat frame is installed across the first side wing support 11 and the second side wing support 12. The first side wing support 11 and the second side wing support 12 of the seat frame 10 are connected by the rear crossbeam 20, which helps to improve the structural stability of the seat frame 10.

[0029] In some embodiments of this application, such as embodiments where the cushion frame 10 includes a first side wing support 11 and a second side wing support 12, see [reference]. Figure 1 as well as Figure 2 , Figure 2 A schematic diagram of a lifting assembly 30 in an embodiment of this application is shown. The lifting assembly 30 includes a lifting rod 31, which has a first side wing rod 311, a second side wing rod 312, and a crossbar 313. The first side wing rod 311 is parallel to the first side wing support 11, the second side wing rod 312 is parallel to the second side wing support 12, and the crossbar 313 is parallel to the rear crossbeam 20 of the seat frame.

[0030] It should be noted that in the above embodiment, the first side wing rod 311 can be set close to the first side wing bracket 11, the second side wing rod 312 can be set close to the second side wing bracket 12, and the crossbar 313 can be set close to the rear crossbeam 20 of the seat frame. Therefore, the first side wing rod 311, the second side wing rod 312, and the crossbar 313 form a C-shaped lifting rod 31. This shape of the lifting rod 31 can reduce the volume occupied by the internal space of the seat cushion frame 10. At the same time, when the lifting assembly 30 is in the first rotation position driven by the drive assembly 40, the crossbar 313 can lift the seat cushion foam on the seat cushion frame 10, thereby reducing the height difference between the seat cushion support plane and the backrest support plane after the seat back is folded down.

[0031] It is understood that the lifting rod 31 with the first side wing rod 311, the second side wing rod 312 and the crossbar 313 is only an exemplary embodiment of this application. Those skilled in the art can set the shape and structure of the lifting rod 31 according to actual needs (e.g., the internal mounting structure or moving parts of the cushion frame 10).

[0032] In some embodiments of this application, see further reference. Figure 1 as well as Figure 2 The lifting assembly 30 also includes a drive plate 32, which is rotatably mounted on the seat frame 10. The lifting rod 31 is fixed on the drive plate 32, and the drive plate 32 has a gear part 321. When the drive assembly 40 drives the gear part 321 to rotate through a transmission structure (e.g., a gear), the drive plate 32 can drive the lifting rod 31 to rotate to a first rotation position or a second rotation position.

[0033] In some embodiments of this application, the drive plate 32 is rotatably fixed to the first side wing bracket 11, the first side wing rod 311 is connected to the drive plate 32, and the second side wing rod 312 is rotatably fixed to the second side wing bracket 12. Exemplarily, the drive plate 32 is rotatably connected to the first side wing bracket 11 via a rotation shaft, thereby enabling it to rotate around the rotation shaft under external force. Through the rotational engagement between the drive plate 32 and the first side wing bracket 11, and the rotational engagement between the second side wing rod 312 and the second side wing bracket 12, the lifting rod 31 can rotate relative to the seat cushion frame 10 under the drive of the drive plate 32.

[0034] In some embodiments of this application, the connection point between the first side wing rod 311 and the drive plate 32 is located on the side of the drive plate 32's rotation axis opposite to the gear portion 321. For example, see [reference needed]. Figure 1 , Figure 2 as well as Figure 3 , Figure 3A schematic diagram of a drive plate 32 in one embodiment of this application is shown. The drive plate 32 has a fixing groove 322 at one end opposite to the gear part 321. A first side wing rod 311 is partially fixed in the fixing groove 322. The drive plate 32 is rotatably fixed to the first side wing bracket 11, and the second side wing rod 312 is rotatably fixed to the second side wing bracket 12. That is, the first side wing rod 311 can rotate with the drive plate 32 relative to the first side wing bracket 11, and the second side wing rod 312 can rotate directly relative to the second side wing bracket 12. Overall, the lifting assembly 30 has two rotational support points relative to the seat cushion frame 10, thus ensuring the rotational reliability of the lifting assembly 30 and providing stable support to the user when the lifting assembly 30 is in the first rotational position. See also some embodiments of this application. Figure 5 and Figure 6 The connection between the first side wing rod 311 and the drive plate 32 is located between the rotation axis of the drive plate 32 and the gear part 321. This arrangement brings the rotation axis of the drive plate 32 closer to the front of the seat, allowing the drive plate 32 to obtain a larger lever arm when rotated under force, thus achieving more efficient transmission output under the same driving force. This structural layout helps reduce the driving load, improves the smoothness of transmission, and also facilitates the arrangement of components in a limited space, resulting in better space utilization.

[0035] In some embodiments of this application, see further reference. Figure 1 as well as Figure 3 The drive plate 32 has a rotating shaft hole 323 and a limiting groove 324. The limiting groove 324 is arc-shaped with the center of the rotating shaft hole 323 as the center. A limiting rod (not shown in the figure) is installed in the limiting groove 324. Specifically, the limiting rod is fixed to the seat frame 10. When the drive plate 32 rotates around the rotating shaft hole 323, the position of the limiting rod relative to the limiting groove 324 changes. Therefore, the limiting rod can limit the rotation position of the drive plate 32, thereby helping to avoid the phenomenon of excessive rotation of the drive plate 32.

[0036] For example, when the lifting assembly 30 is in the first rotational position, the limiting rod can contact the inner wall surface of one end of the limiting groove 324, and when the lifting assembly 30 is in the second rotational position, the limiting rod can contact the inner wall surface of the other end of the limiting groove 324, thereby limiting the rotation angle of the drive plate 32.

[0037] It is understood that the implementation of limiting the rotation of the drive plate 32 is not limited to this. For example, a limiting rod can be provided on the drive plate 32, and a limiting groove 324 can be provided on the first side wing bracket 11. The position of the limiting rod can be limited by the limiting groove 324, thereby avoiding the phenomenon of excessive rotation of the drive plate 32.

[0038] In some embodiments of this application, see Figure 4 , Figure 4 This diagram illustrates a partial structure of the drive assembly 40 and the lifting assembly 30 in an embodiment of this application. The drive assembly 40 includes a drive gear 41 and a drive motor (not shown). The drive gear 41 meshes with a gear section 321, and the drive motor drives the drive gear 41 to rotate. Specifically, the drive gear 41 is rotatably fixed to the seat frame 10. The drive motor can drive the drive gear 41 to rotate through a transmission structure (e.g., gear, rack, belt, or worm gear transmission structure), so that the drive gear 41 can drive the gear section 321 meshing with it to rotate, ultimately causing the lifting rod 31 to rotate.

[0039] In some embodiments of this application, the drive motor can be fixed to the side of the first side wing bracket 11 away from the second side wing bracket 12, that is, the drive motor is located outside the seat cushion frame 10 rather than inside between the first side wing bracket 11 and the second side wing bracket 12, which helps to avoid affecting the arrangement of other components inside the seat cushion frame 10, and can ultimately be applied to seats in a lower position.

[0040] It is worth noting that the above content regarding the seat is intended to clearly illustrate the implementation and verification process of this application. Those skilled in the art can also make equivalent design modifications under the guidance of this application. For example, the drive assembly 40 can also drive the drive plate 32 and the lifting rod 31 to rotate via a belt, worm gear, or rack and pinion transmission mechanism.

[0041] Furthermore, to better implement the seats in the embodiments of this application, this application also provides a vehicle, which includes a seat as described in any of the above embodiments.
