[0001] The present application relates to the field of seat adjustment, and in particular to a seat adjustment device, method and automobile seat assembly. Background Art

[0002] With the development and iteration of the automobile industry, cars have also become an important part of living space. The contour switch is a seat adjustment device, which can have multiple buttons corresponding to different parts of the seat. Moreover, the contour switch is generally arranged on the door panel of the car, and the user can see the hardware entity at the same time when operating it, allowing the user to intuitively understand the functions corresponding to different buttons. At present, rotating seats are launched on the market, which can achieve different seat orientations. However, for vehicles equipped with rotatable seats, when the seat is rotated, the contour switch is limited to the adjustment function corresponding to the original seat posture, and the user can no longer intuitively understand the functions corresponding to different buttons, but loses the intuitiveness of operation.

[0003] Currently, no effective solution has been proposed for the problem in the related art that the seat adjustment device loses its intuitiveness in operation after the seat is rotated. Summary of the invention

[0010] The control module is used to switch the working mode of each of the adjustment units, so that the working modes of two adjustment units that are axially symmetrically distributed are swapped with each other.

[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.

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

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

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

[0019] In a second aspect, a seat adjustment method is provided in this embodiment, which is applied to the seat adjustment device described in the first aspect. The method includes:

[0020] In response to the change in the seat orientation, the rotation mechanism is triggered to rotate, and the working mode of each adjustment unit is switched, so that the working modes of the two adjustment units that are axially symmetrically distributed are swapped with each other.

[0034] Figure 1 Schematic diagram of the application environment of the profile switch in the related art, such as Figure 1 As shown, the vehicle is provided with a rotatable seat and a contour switch, and the contour switch is arranged on the door panel. Before the seat rotates, the contour switch and the seat are similar in shape. After the seat rotates, the orientation of the seat will change, for example, from facing the front of the vehicle to facing the rear of the vehicle. At this time, since the door panel is fixed in position and the shape of the contour switch is arranged according to the shape of the seat, the shape of the contour switch on the door panel cannot intuitively indicate the adjustment function of each part of the seat, and once the seat orientation indicated by the contour switch is different from the actual orientation of the seat, it will mislead the user visually.

[0035] Based on the analysis of the above situation, in one embodiment, a seat adjustment device is provided. Figure 2 Schematic diagram of the structure of the seat adjustment device, as shown in Figure 2 As shown, the seat adjustment device includes: a rotating mechanism 1 and an adjusting mechanism 2 that are interconnected; wherein the rotating mechanism 1 is used to drive the adjusting mechanism 2 to rotate when rotating; the adjusting mechanism 2 includes a plurality of adjusting units (such as A, B, C, D, E or at least two thereof), each adjusting unit corresponding to adjusting a different part of the seat; the plurality of adjusting units are axially symmetrically distributed, and the shapes of the adjusting mechanism 2 before and after rotation are axially symmetrical.

[0036] In this embodiment, the adjustment mechanism 2 includes a plurality of adjustment units, each of which corresponds to adjusting a different part of the seat. Each adjustment unit can imitate the appearance design of the seat, so that the user can visually correspond to the adjustment function of different adjustment units. By setting a rotating mechanism 1 in the seat adjustment device, the adjustment mechanism 2 can be driven to rotate when the rotating mechanism 1 rotates, so that after the seat rotates, the seat adjustment device can also rotate. Among them, the seat adjustment device can be installed on the door panel of the vehicle, and the seat adjustment device can be linked to the seat rotation, or the user can manually operate the seat adjustment device to rotate, which is not limited in this embodiment.

[0037] Before the adjustment mechanism 2 rotates, the shape of the adjustment mechanism 2 is similar to that of the seat. After the adjustment mechanism 2 rotates, since the multiple adjustment units of the adjustment mechanism 2 are axially symmetrically distributed, and the shapes of the adjustment mechanism 2 before and after the rotation are axially symmetrical, that is, the shapes of the adjustment mechanism 2 before and after the rotation are mirror-symmetrical, this will make the shape of the adjustment mechanism 2 still similar to that of the seat, so it can intuitively indicate the adjustment functions of various parts of the seat. In this way, after the seat rotates, the seat adjustment device is still intuitive to operate and will not mislead the user visually.

[0038] The adjustment mechanism 2 can have various structures, for example:

[0039] Structure 1: Reference Figure 2 , the adjustment mechanism 2 includes: a headrest adjustment unit A and a leg rest adjustment unit D, and the headrest adjustment unit A and the leg rest adjustment unit D are axially symmetrically distributed. In this embodiment, when the seat orientation changes, the rotating mechanism 1 can drive the adjustment mechanism 2 to rotate by rotating, 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 that originally corresponds to the headrest part of the seat will correspond to the leg rest part of the seat, and the leg rest adjustment unit D that originally corresponds to the leg rest part will correspond to the headrest part. In this way, the shape of the adjustment mechanism 2 after rotation is still similar to the seat, and the seat adjustment device is still 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, and the backrest adjustment unit B and the seat cushion adjustment unit C are axially symmetrically distributed. In this embodiment, when the seat orientation changes, the rotating mechanism 1 can drive the adjustment mechanism 2 to rotate by rotating, and the positions of the backrest adjustment unit B and the seat cushion adjustment unit C on the adjustment mechanism 2 will be swapped, that is, the backrest adjustment unit B originally corresponding to the seat back position will correspond to the seat cushion position, and the seat cushion adjustment unit C originally corresponding to the seat cushion position will correspond to the backrest position. In this way, the shape of the adjustment mechanism 2 after rotation is still similar to the seat, and the seat adjustment device is still 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, wherein the headrest adjustment unit A and the leg rest adjustment unit D are axially symmetrically distributed, and the seat cushion adjustment unit C and the leg rest adjustment unit D are axially symmetrically distributed. In this embodiment, when the seat orientation changes, the rotating mechanism 1 can drive the adjustment mechanism 2 to rotate by rotating, 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 originally corresponding to the headrest part will correspond to the leg rest part, and the leg rest adjustment unit D originally corresponding to the leg rest part will correspond to the headrest part. 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 originally corresponding to the backrest part will correspond to the seat cushion part, and the seat cushion adjustment unit C originally corresponding to the seat cushion part will correspond to the backrest part. In this way, the shape of the adjustment mechanism 2 after rotation is still similar to the seat, and the seat adjustment device is still intuitive to operate.

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

[0043] In one embodiment, reference Figure 2 , a schematic diagram of the adjustment function of a seat adjustment device is provided, and the 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; wherein, the headrest adjustment unit A and the leg support adjustment unit D are axially symmetrically distributed, the backrest adjustment unit B and the seat cushion adjustment unit C are axially symmetrically distributed, and the lumbar support adjustment unit E is located on the symmetry axis. In order to enrich the function of the adjustment mechanism 2, each adjustment unit includes at least two adjustment areas with different operating directions. Taking the arrangement of the seat adjustment device on the right door panel in the vehicle as an example, before the seat rotates, it faces the front of the vehicle. At this time, 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 (the front, back, up, down, etc. directions are all relative to the user in the current seat):

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

[0067] x) E-4: Lumbar support adjusted backwards.

[0068] The user can trigger the seat rotation through physical buttons, voice input or screen gestures in the car, and the rotating mechanism will also rotate until the rotating mechanism rotates to a certain angle (for example, 90° clockwise), so that the entire adjustment mechanism is mirror-symmetrical before and after the rotation. At this time, the seat faces the rear of the vehicle, and the position 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 (the front, back, up, down, etc. directions are all relative to the user in the current seat):

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

[0092] x) E-4: Lumbar support adjusted downward.

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

[0094] In this embodiment, the control module can be implemented by MCU (Microcontroller Unit), and two sets of control logic are built in the MCU. When the adjustment mechanism is in the first form, the control module triggers the first control logic, so that the adjustment mechanism adopts the first working mode; when the adjustment mechanism is in the second form, the control module triggers the second control logic, so that the adjustment mechanism adopts the second working mode. For example, the form of the adjustment mechanism before rotation is defined as the first form, 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 form, the positions of the headrest adjustment unit and the backrest adjustment unit on the adjustment mechanism will be swapped, and the headrest adjustment unit originally corresponding to the headrest part will correspond to the backrest part, and the backrest adjustment unit originally corresponding to the backrest part will correspond to the headrest part. At this time, the control module triggers the second control logic, so that the adjustment mechanism adopts the second working mode. The same setting is made for other adjustment units, which will not be repeated here. In this embodiment, when the seat is in different orientations before and after rotation, the seat adjustment device can not only intuitively map different seat parts, but also achieve correct mapping of the adjustment function.

[0095] In one embodiment, the control module can be triggered by the seat or the rotating mechanism to switch the control logic, thereby switching the working mode of each adjustment unit. The seat can be adjusted in direction through the seat control device.

[0096] This embodiment also provides a seat adjustment method, which is applied to any of the above-mentioned seat adjustment devices, and the method includes: in response to the change of the seat orientation, triggering the rotation of the rotation mechanism, and switching the working mode of each adjustment unit, so that the working modes of the two adjustment units distributed axially symmetrically are swapped with each other. In this embodiment, any one of the following solutions 1 to 5 can be used to implement the seat adjustment method.

[0097] Solution 1: If Figure 7As shown, the control module 3 and the rotating mechanism 1 are respectively connected to the seat control device 4 of the seat. When the seat control device 4 controls the change of the seat orientation, the seat control device 4 will send a signal to the rotating mechanism 1 and the control module 3, directly triggering the rotation of the rotating mechanism 1, and triggering the control module 3 to switch 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 the intelligent and humanized seat adjustment.

[0098] Solution 2: If 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 of the seat. In this embodiment, the seat first triggers the rotating mechanism 1 to rotate, and the rotating mechanism 1 then 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 the working mode, realizing the intelligent and humanized seat adjustment.

[0099] Solution 3: If Fig. 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 change of the seat orientation, 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 automatically switches the working mode, realizing the intelligent and humanized seat adjustment.

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

[0101] Solution 5: The seat, rotating mechanism 1, and control module 3 can respectively respond to user instructions, change the seat orientation, start the rotating mechanism 1, and trigger the control module 3 to switch the working mode of each adjustment unit. Optionally, the rotating mechanism 1 has a built-in drive motor for driving the rotation. Optionally, user instructions include but are not limited to voice instructions, screen gesture operations, and physical button operations. In this embodiment, users are supported to 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 the special structure of the seat adjustment device and the corresponding signal control logic in different forms, can realize flexible and intuitive control to meet the different orientations of the car seat; it can support the upward, downward, forward and backward adjustment of the headrest; the forward and backward adjustment of the backrest angle; the upward and downward adjustment of the seat cushion angle; the upward and downward adjustment of the seat cushion height; the forward and backward adjustment of the seat cushion position; the extension and shortening adjustment of the seat cushion; the upward and downward adjustment of the leg support; the upward, downward, forward and backward adjustment of the lumbar support. Since the seat adjustment device can form two mirror positions by rotating in structure, the same set of hardware (mold) can be used to correspond to the seats on the left and right sides of the vehicle, and there is no need to separately open molds and produce two sets of symmetrical hard switch parts for the seats on the left and right sides, saving hardware costs.

[0103] In one embodiment, a car seat assembly is provided, which comprises a rotatable seat and a seat adjustment device according to any one of the above embodiments.

[0104] refer to Figure 2 , the seat adjustment device includes a rotating mechanism 1 and an adjusting mechanism 2 which are 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 a plurality of adjusting units, each adjusting unit corresponding to adjusting a different part of the seat; the plurality of adjusting units are axially symmetrically distributed, and the shapes of the adjusting mechanism 2 before and after rotation are axially symmetrical. Wherein, the rotatable seat includes at least a backrest and a seat cushion. Accordingly, the adjusting mechanism 2 includes a backrest adjustment unit B and a seat cushion adjustment unit C. Optionally, in order to increase the comfort of the rotatable seat, the rotatable seat may also include a headrest, a leg rest and a lumbar rest. Accordingly, the adjusting mechanism 2 may also include a headrest adjustment unit A, a leg rest adjustment unit D and a lumbar support adjustment unit E.

[0105] The adjustment mechanism 2 includes a plurality of adjustment units, each of which corresponds to adjusting a different part of the seat. Each adjustment unit can imitate the appearance design of the seat, so that the user can visually correspond to the adjustment function of different adjustment units. By setting a rotating mechanism 1 in the seat adjustment device, the adjustment mechanism 2 can be driven to rotate when the rotating mechanism 1 rotates, so that after the seat rotates, the seat adjustment device can also rotate. The seat adjustment device can be installed on the door panel of the vehicle, and the seat adjustment device can be linked to the seat rotation, or the user can manually operate the seat adjustment device to rotate, which is not limited in this embodiment.

[0106] Before the adjustment mechanism 2 rotates, the shape of the adjustment mechanism 2 is similar to that of the seat. After the adjustment mechanism 2 rotates, since the multiple adjustment units of the adjustment mechanism 2 are axially symmetrically distributed, and the shapes of the adjustment mechanism 2 before and after the rotation are axially symmetrical, that is, the shapes of the adjustment mechanism 2 before and after the rotation are mirror-symmetrical, this will make the shape of the adjustment mechanism 2 still similar to that of the seat, so that the adjustment functions of various parts of the seat can be intuitively indicated. In this way, after the seat rotates, the seat adjustment device is still intuitive to operate and will not mislead the user visually.
