Description

Technical Field

[0001] This application relates to the field of seat adjustment, and in particular to a seat adjustment device, method and automotive seat assembly. Background Technology

[0002] With the evolution of the automotive industry, cars have become an important part of living spaces. A contour switch is a seat adjustment device with multiple buttons, each corresponding to a different part of the seat. These switches are typically located on the car door panel, allowing users to see the physical hardware and intuitively understand the functions of each button. Currently, rotating seats are available, allowing for different seating orientations. However, in vehicles equipped with rotating seats, when the seat is rotated, the contour switch's adjustment function is limited to the original seat posture, making it difficult for users to intuitively understand the functions of each button, thus losing its intuitive operation.

[0003] Currently, no effective solution has been proposed to address the issue that seat adjustment devices lose their intuitive operation after the seat is rotated in related technologies. Summary of the Invention

[0004] Therefore, it is necessary to provide a seat adjustment device, method, and automotive seat assembly that can maintain intuitive operation even after the seat has been rotated, in order to address the aforementioned technical problems.

[0005] In a first aspect, this application provides a seat adjustment device, comprising: a rotating mechanism and an adjusting mechanism interconnected thereto; wherein...

[0006] The rotating mechanism is used to drive the adjusting mechanism to rotate during rotation;

[0007] The adjustment mechanism includes multiple adjustment units, each of which adjusts a different part of the seat.

[0008] The multiple adjustment units are axially symmetrically distributed, and the adjustment mechanism is axially symmetrical in shape before and after rotation.

[0009] In one embodiment, the seat adjustment device further includes: a control module connected to the adjustment mechanism; wherein,

[0010] The control module is used to switch the working modes of each of the adjustment units, so that the working modes of two adjustment units that are symmetrically distributed on an axis can be interchanged.

[0011] In one embodiment, the control module is connected to the rotating mechanism and / or the seat control device of the seat; wherein,

[0012] The seat control device is used to adjust the orientation of the seat.

[0013] In one embodiment, the rotating mechanism is connected to the seat control device of the seat.

[0014] In one embodiment, the plurality of adjustment units include at least one of the following:

[0015] Headrest adjustment unit, backrest adjustment unit, seat cushion adjustment unit, leg support adjustment unit, lumbar support adjustment unit.

[0016] In one embodiment, the headrest adjustment unit and the leg support adjustment unit are symmetrically distributed along an axis; the backrest adjustment unit and the seat cushion adjustment unit are symmetrically distributed along an axis; and the lumbar support adjustment unit is located on the axis of symmetry.

[0017] In one embodiment, the seat adjustment device is mounted on the door panel of the vehicle.

[0018] In one embodiment, each of the adjustment units includes adjustment regions with at least two different operating directions.

[0019] Secondly, this embodiment provides a seat adjustment method, applied to the seat adjustment device described in the first aspect above, the method comprising:

[0020] In response to a change in seat orientation, the rotating mechanism is triggered to rotate and the operating modes of each adjustment unit are switched, so that the operating modes of the two adjustment units that are symmetrically distributed on the axis are interchanged.

[0021] Thirdly, this embodiment provides an automotive seat assembly, including: a rotatable seat and the seat adjustment device described in the first aspect above.

[0022] The aforementioned seat adjustment device, method, and automotive seat assembly, by adding a rotating mechanism, allow the adjustment mechanism to rotate after the seat orientation is changed. Furthermore, because the multiple adjustment units of the adjustment mechanism are axially symmetrically distributed, and the shape of the adjustment mechanism before and after rotation is also axially symmetrical—that is, its shape is mirror-symmetrical before and after rotation—the shape of the adjustment mechanism remains similar to that of the seat. Therefore, the adjustment functions of each part of the seat can be intuitively indicated. Thus, the seat adjustment device remains intuitive to operate after the seat is rotated, and will not visually mislead the user. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] Unless otherwise defined, the technical or scientific terms used in this application shall have the general meaning as understood by one of ordinary skill in the art to which this application pertains. Words such as “a,” “an,” “an,” “the,” “the,” and “these,” used in this application, do not indicate quantitative limitation and may be singular or plural. The terms “comprising,” “including,” “having,” and any variations thereof used in this application are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or modules (units) is not limited to the listed steps or modules (units) but may include steps or modules (units) not listed, or may include other steps or modules (units) inherent to such processes, methods, products, or devices. The terms “connected,” “linked,” and “coupled,” used in this application, are not limited to physical or mechanical connections but may include electrical connections, whether direct or indirect. The term “multiple” used in this application refers to two or more. The "and / or" operator describes the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: A alone, A and B simultaneously, and B alone. Typically, the character " / " indicates that the objects before and after it are in an "or" relationship. The terms "first," "second," and "third," etc., used in this application are merely for distinguishing similar objects and do not represent a specific ordering of the objects.

[0034] Figure 1 This is a schematic diagram illustrating the application environment of contour switches in related technologies, such as... Figure 1 As shown, the vehicle is equipped with a rotatable seat and contour switches, with the contour switches located on the door panel. Before the seat rotates, the shape of the contour switches is similar to that of the seat. After the seat rotates, the seat's orientation changes, for example, from facing the front of the vehicle to facing the rear. At this time, because the door panel position is fixed and the shape of the contour switches is arranged according to the shape of the seat, the shape of the contour switches on the door panel cannot intuitively indicate the adjustment functions of various parts of the seat. Moreover, if the seat orientation indicated by the contour switches differs from the actual seat orientation, it can be visually misleading to the user.

[0035] Based on the analysis of the above situation, in one embodiment, a seat adjustment device is provided. Figure 2 This is a schematic diagram of the seat adjustment device, as shown below. Figure 2 As shown, the seat adjustment device includes a rotating mechanism 1 and an adjusting mechanism 2 connected to each other; wherein, the rotating mechanism 1 is used to drive the adjusting mechanism 2 to rotate when rotating; the adjusting mechanism 2 includes multiple adjusting units (e.g., A, B, C, D, E or at least two of them), each adjusting unit corresponding to different parts of the seat; the multiple adjusting units are axially symmetrically distributed, and the shape of the adjusting mechanism 2 before and after rotation is axially symmetrical.

[0036] In this embodiment, the adjustment mechanism 2 includes multiple adjustment units, each corresponding to different parts of the seat. Each adjustment unit can mimic the shape of the seat, allowing the user to visually and intuitively understand the adjustment functions of different units. By incorporating a rotating mechanism 1 into the seat adjustment device, the rotation of the rotating mechanism 1 drives the adjustment mechanism 2 to rotate, thus enabling the seat adjustment device to rotate as well after the seat rotates. The seat adjustment device can be installed on the vehicle's door panel. It can rotate in conjunction with the seat, or it can be manually operated by the user; this embodiment does not impose any limitations.

[0037] Before the adjustment mechanism 2 rotates, its shape resembles that of the seat. After rotation, because the multiple adjustment units of the adjustment mechanism 2 are axially symmetrically distributed, and the shape of the adjustment mechanism 2 before and after rotation is also axially symmetrical (i.e., its shape is mirror-symmetrical), the shape of the adjustment mechanism 2 remains similar to that of the seat. Therefore, the adjustment functions of each part of the seat can be intuitively indicated. In this way, the seat adjustment device remains intuitive to operate after the seat rotates, and will not visually mislead the user.

[0038] The adjusting mechanism 2 can have various structures, as shown in the following examples:

[0039] Structure 1: Reference Figure 2 The adjustment mechanism 2 includes a headrest adjustment unit A and a leg rest adjustment unit D, which are symmetrically distributed along an axis. In this embodiment, when the seat orientation changes, the rotation mechanism 1 can rotate the adjustment mechanism 2, and the positions of the headrest adjustment unit A and the leg rest adjustment unit D on the adjustment mechanism 2 will be swapped. That is, the headrest adjustment unit A, which originally corresponded to the headrest area, will now correspond to the leg rest area, and the leg rest adjustment unit D, which originally corresponded to the leg rest area, will now correspond to the headrest area. In this way, the shape of the adjustment mechanism 2 after rotation still resembles the seat, and the seat adjustment device remains intuitive to operate.

[0040] Structure 2: Reference Figure 2 The adjustment mechanism 2 includes a backrest adjustment unit B and a seat cushion adjustment unit C, which are symmetrically distributed along an axis. In this embodiment, when the seat orientation changes, the rotation mechanism 1 can rotate the adjustment mechanism 2, causing the positions of the backrest adjustment unit B and the seat cushion adjustment unit C on the adjustment mechanism 2 to be swapped. That is, the backrest adjustment unit B, which originally corresponded to the backrest, will now correspond to the seat cushion, and the seat cushion adjustment unit C, which originally corresponded to the seat cushion, will now correspond to the backrest. This ensures that the shape of the adjustment mechanism 2 after rotation still resembles the seat, and the seat adjustment device remains intuitive to operate.

[0041] Structure 3: Reference Figure 2 The adjustment mechanism 2 includes a headrest adjustment unit A, a backrest adjustment unit B, a seat cushion adjustment unit C, and a leg rest adjustment unit D. The headrest adjustment unit A and the leg rest adjustment unit D are symmetrically distributed along an axis, as are the seat cushion adjustment unit C and the leg rest adjustment unit D. In this embodiment, when the seat orientation changes, the rotation mechanism 1 can rotate the adjustment mechanism 2, causing the positions of the headrest adjustment unit A and the leg rest adjustment unit D on the adjustment mechanism 2 to be swapped. That is, the headrest adjustment unit A, which originally corresponded to the headrest area, will now correspond to the leg rest area, and the leg rest adjustment unit D, which originally corresponded to the leg rest area, will now correspond to the headrest area. Similarly, the positions of the backrest adjustment unit B and the seat cushion adjustment unit C will be swapped. That is, the backrest adjustment unit B, which originally corresponded to the backrest area, will now correspond to the seat cushion area, and the seat cushion adjustment unit C, which originally corresponded to the seat cushion area, will now correspond to the backrest area. This ensures that the shape of the adjustment mechanism 2 after rotation still resembles the seat, and the seat adjustment device remains intuitive to operate.

[0042] Structure 4: Based on any of the above-mentioned adjustment mechanisms 2, it may further include a lumbar support adjustment unit E, which is located on the axis of symmetry. It can be understood that the lumbar support adjustment unit E corresponds to the lumbar support area of ​​the seat. When the seat orientation changes, and the rotating mechanism 1 drives the adjustment mechanism 2 to rotate, the position of the lumbar support adjustment unit E remains unchanged, ensuring that the shape of the adjustment mechanism 2 after rotation still resembles the seat, and the seat adjustment device remains intuitive to operate.

[0043] In one embodiment, reference Figure 2 This document provides a schematic diagram of the adjustment functions of a seat adjustment device. Multiple adjustment units include: a headrest adjustment unit A, a backrest adjustment unit B, a seat cushion adjustment unit C, a leg support adjustment unit D, and a lumbar support adjustment unit E. The headrest adjustment unit A and leg support adjustment unit D are symmetrically arranged along an axis of symmetry, as are the backrest adjustment unit B and seat cushion adjustment unit C. The lumbar support adjustment unit E is located on the axis of symmetry. To enrich the functions of the adjustment mechanism 2, each adjustment unit includes adjustment areas with at least two different operating directions. Taking the seat adjustment device located on the right-side door panel of the vehicle as an example, before the seat rotates and faces forward, the positional relationship between the seat adjustment device and the seat is as follows: Figure 3 As shown, the operating direction of each adjustment unit and the corresponding seat part is as follows: Figure 4 As shown (all directions, such as front, back, up, and down, are relative to the user currently in the seat):

[0044] a) A-1: ​​Adjust the headrest position upwards;

[0045] b) A-2: Adjust the headrest position downwards;

[0064] u)E-1: Adjust the lumbar support upwards;

[0065] v)E-2: Lumbar support adjusted downwards;

[0066] w)E-3: Lumbar support adjusted forward;

[0067] x)E-4: Adjust the lumbar support backward.

[0068] Inside the vehicle, users can trigger seat rotation via physical buttons, voice input, or screen gestures. The rotation mechanism will then rotate until it reaches a certain angle (e.g., 90° clockwise), resulting in a mirror-image symmetrical shape of the entire adjustment mechanism before and after the rotation. At this point, the seat faces the rear of the vehicle, and the positional relationship between the seat adjustment device and the seat is as follows: Figure 5As shown, the operating direction of each adjustment unit and the corresponding seat part is as follows: Figure 6 As shown (all directions, such as front, back, up, and down, are relative to the user currently in the seat):

[0069] a) A-1: ​​Leg support extension adjustment;

[0070] b) A-2: Leg rest shortening adjustment;

[0091] w)E-3: Lumbar support adjusted upwards;

[0092] x)E-4: Adjust the lumbar support downwards.

[0093] In one embodiment, the seat adjustment device further includes a control module connected to the adjustment mechanism; wherein the control module is used to switch the working modes of each adjustment unit so that the working modes of two adjustment units that are symmetrically distributed are interchanged.

[0094] In this embodiment, the control module can be implemented using an MCU (Microcontroller Unit), which has two sets of built-in control logic. When the adjustment mechanism is in the first state, the control module triggers the first control logic, causing the adjustment mechanism to adopt the first working mode. When the adjustment mechanism is in the second state, the control module triggers the second control logic, causing the adjustment mechanism to adopt the second working mode. For example, the state before the adjustment mechanism rotates is defined as the first state, and the corresponding working mode is defined as the first working mode. At this time, the position of the headrest adjustment unit corresponds to the headrest part, and the position of the backrest adjustment unit corresponds to the backrest part. The control module triggers the first control logic. When the adjustment mechanism rotates and is in the second state, the positions of the headrest adjustment unit and the backrest adjustment unit on the adjustment mechanism will be swapped. The headrest adjustment unit that originally corresponded to the headrest part will correspond to the backrest part, and the backrest adjustment unit that originally corresponded to the backrest part will correspond to the headrest part. At this time, the control module triggers the second control logic, causing the adjustment mechanism to adopt the second working mode. The same setting applies to other adjustment units, which will not be described in detail here. In this embodiment, when the seat is in different orientations before and after rotation, the seat adjustment device can not only visually map different seat parts, but also achieve the correct mapping of adjustment functions.

[0095] In one embodiment, the control module can switch control logic via the seat or rotation mechanism, thereby switching the operating modes of each adjustment unit. The seat can be adjusted for orientation via a seat control device.

[0096] This embodiment also provides a seat adjustment method, applicable to any of the aforementioned seat adjustment devices. The method includes: in response to a change in seat orientation, triggering a rotating mechanism to rotate, and switching the operating modes of each adjustment unit, such that the operating modes of two axisily symmetrically distributed adjustment units are interchanged. In this embodiment, any one of the following schemes 1 to 5 can be used to implement the seat adjustment method.

[0097] Option 1: As Figure 7As shown, the control module 3 and the rotating mechanism 1 are respectively connected to the seat control device 4. When the seat control device 4 changes the seat orientation, it sends signals to the rotating mechanism 1 and the control module 3, directly triggering the rotating mechanism 1 to rotate and the control module 3 to switch the operating modes of each adjustment unit. Optionally, the rotating mechanism 1 has a built-in drive motor for driving the rotation. In this embodiment, when the seat orientation changes, the rotating mechanism 1 will automatically rotate accordingly, and the control module 3 will automatically switch the operating mode, realizing intelligent and user-friendly seat adjustment.

[0098] Option 2: As Figure 8 As shown, the control module 3 is connected to the rotating mechanism 1, and the rotating mechanism 1 is connected to the seat control device 4. In this embodiment, the seat first triggers the rotating mechanism 1 to rotate, and then the rotating mechanism 1 triggers the control module 3 to switch modes. Optionally, the rotating mechanism 1 has a built-in drive motor for driving the rotation. In this embodiment, when the seat orientation changes, the rotating mechanism 1 will automatically follow the rotation, and the control module 3 will automatically switch working modes, realizing intelligent and user-friendly seat adjustment.

[0099] Option 3: such as Figure 9 As shown, the control module 3 is connected to the rotating mechanism 1 and the seat control device 4 of the seat, respectively. When the seat control device 4 controls the seat orientation to change, the seat control device 4 first sends a signal to the control module 3, and then the control module 3 triggers the rotating mechanism 1 to rotate, and the control module 3 switches the working mode of each adjustment unit. Optionally, the rotating mechanism 1 has a built-in drive motor for driving the rotation. In this embodiment, when the seat orientation changes, the rotating mechanism 1 will automatically follow the rotation, and the control module 3 will automatically switch the working mode, realizing intelligent and user-friendly seat adjustment.

[0100] Option 4: The control module 3 is connected to the rotating mechanism 1 or the seat control device 4. When the seat control device 4 controls the seat orientation to change, the user manually adjusts the rotation mechanism 1. At this time, the seat control device 4 can send a signal to the control module 3 to trigger its switching of operating modes; alternatively, the rotating mechanism 1 can send a signal to the control module 3 to trigger its switching of the operating modes of each adjustment unit; or the control module 3 can actively detect the rotation of the rotating mechanism 1 before switching the operating modes of each adjustment unit. In this embodiment, when the seat orientation changes, the user can decide whether to change the operating mode of the adjustment mechanism 2, making the use of the seat adjustment device more flexible.

[0101] Option 5: The seat, rotating mechanism 1, and control module 3 can each respond to user commands to change the seat orientation, activate rotating mechanism 1, and trigger control module 3 to switch the operating modes of each adjustment unit. Optionally, rotating mechanism 1 has a built-in drive motor for driving rotation. Optionally, user commands include, but are not limited to, voice commands, screen gesture operations, and physical button operations. In this embodiment, users can flexibly control the seat, rotating mechanism 1, and control module 3, making the use of the seat adjustment device more flexible.

[0102] The seat adjustment device provided in this embodiment, through its special structure and corresponding signal control logic in different configurations, achieves flexible and intuitive control for different orientations of the car seat. It can accommodate adjustments to the headrest (up, down, forward, and backward); the backrest angle (forward and backward); the seat cushion angle (up and down); the seat cushion height (up and down); the seat cushion position (forward and backward); the seat cushion extension / retraction adjustment; the leg rest (up and down); and the lumbar support (up, down, forward, and backward). Because the seat adjustment device can be rotated to form two mirror-image positions, the same set of hardware (mold) can be used for both sides of the vehicle's seats, eliminating the need to separately mold and produce two sets of symmetrical hard-switch parts for each side, thus saving hardware costs.

[0103] In one embodiment, an automotive seat assembly is provided. The automotive seat assembly includes: a rotatable seat and a seat adjustment device according to any of the above embodiments.

[0104] refer to Figure 2 The seat adjustment device includes a rotating mechanism 1 and an adjusting mechanism 2 connected to each other. The rotating mechanism 1 drives the adjusting mechanism 2 to rotate during rotation. The adjusting mechanism 2 includes multiple adjusting units, each corresponding to a different part of the seat. The multiple adjusting units are axially symmetrically distributed, and the adjusting mechanism 2 is axially symmetrical in its shape before and after rotation. The rotatable seat includes at least a backrest and a seat cushion. Accordingly, the adjusting mechanism 2 includes a backrest adjusting unit B and a seat cushion adjusting unit C. Optionally, to increase the comfort of the rotatable seat, it may also include a headrest, leg rest, and lumbar support. Accordingly, the adjusting mechanism 2 may also include a headrest adjusting unit A, a leg rest adjusting unit D, and a lumbar support adjusting unit E.

[0105] The adjustment mechanism 2 includes multiple adjustment units, each corresponding to different parts of the seat. Each adjustment unit can mimic the shape of the seat, allowing the user to visually and intuitively identify the adjustment functions of each unit. By incorporating a rotating mechanism 1 within the seat adjustment device, the rotation of the rotating mechanism 1 drives the adjustment mechanism 2 to rotate, thus enabling the seat adjustment device to rotate as well. The seat adjustment device can be mounted on the vehicle's door panel. It can rotate in conjunction with the seat, or it can be manually operated by the user; this embodiment does not impose any limitations.

[0106] Before the adjustment mechanism 2 rotates, its shape resembles that of the seat. After rotation, because the multiple adjustment units of the adjustment mechanism 2 are axially symmetrically distributed, and the shape of the adjustment mechanism 2 before and after rotation is also axially symmetrical (i.e., its shape is mirror-symmetrical), the shape of the adjustment mechanism 2 remains similar to that of the seat. Therefore, it can intuitively indicate the adjustment functions of various parts of the seat. In this way, the seat adjustment device remains intuitive to operate after the seat rotates, and will not visually mislead the user.
