Description

Technical Field

[0001] This disclosure relates to the field of vehicle component technology, and in particular to seat side wings and their adjustment methods, vehicle seats, and vehicles. Background Technology

[0002] As living standards gradually improve, consumers have increasingly higher demands for vehicle seat comfort. To meet the seating needs of people of different sizes, the position adjustment of seat side wings, which provide lateral support for drivers and passengers, has become a research focus. Among related technologies, there are two main approaches to seat side wing adjustment, based on the different force transmission methods: the first is mechanical transmission, including manual brake cable control and electric screw-slider transmission; the second is pneumatic transmission, which uses the inflation and deflation of air bags on the seat side wings to clamp and relax them.

[0003] However, in the mechanical transmission system, the adjustment speed of the seat side wings is too slow. In the pneumatic transmission system, the seat size requirement is large, and the air pump is too noisy when inflating and deflating, increasing the noise level inside the vehicle. Summary of the Invention

[0004] To overcome the problems existing in the related technologies, this disclosure provides a seat side wing and its adjustment method, a vehicle seat, and a vehicle.

[0005] To achieve the above objectives, according to a first aspect of the present disclosure, a seat side wing is provided, including a mounting member, a support member, and a magnetic adjustment structure, wherein the mounting member is used to connect to the seat body of a vehicle seat, and the support member is used to provide lateral support for the driver and passengers.

[0013] The controller is used to change the energization state of the magnetic adjustment structure according to the detection results of the sensor, so as to adjust the position of the support member in the width direction of the vehicle seat.

[0014] Optionally, both the mounting component and the support component are elongated plate-shaped components, and the mounting component and the support component are spaced apart and arranged opposite to each other in the width direction of the vehicle seat.

[0016] According to another aspect of this disclosure, a vehicle seat is provided, including a seat body and the aforementioned seat side wings, wherein the number of seat side wings is at least two, and the seat side wings connected to the seat body are respectively provided on both sides in the width direction of the vehicle seat.

[0017] According to another aspect of this disclosure, a vehicle is provided, including the aforementioned vehicle seat.

[0018] According to another aspect of this disclosure, a method for adjusting a seat side wing is provided, the seat side wing including a mounting member, a support member and a magnetic adjustment structure, the mounting member being used to connect to the body of a vehicle seat, and the support member being used to provide lateral support for the driver and passengers;

[0019] The magnetic adjustment structure includes a fixed part and a movable part. The fixed part is connected to the mounting member, and the movable part is connected to the support member. The movable part is configured to move relative to the fixed part in the width direction of the vehicle when the energized state of the magnetic adjustment structure changes. The method includes:

[0020] When an adjustment command is received indicating the position of the adjustment support member in the width direction of the vehicle seat, the energization state of the magnetic adjustment structure is changed to control the movement of the fixing part in the width direction of the vehicle seat, thereby driving the support member to move in the width direction of the vehicle seat.

[0021] Optionally, the seat side wing further includes a sensor for detecting the distance between the support and the mounting member in the width direction of the vehicle seat, and the method further includes:

[0022] When the sensor detects a positioning signal, the current flowing through the magnetic adjustment structure is controlled to remain at a preset threshold so that the support remains in the target position.

[0023] Optionally, the adjustment command is an adjustment command generated by an operator to adjust the position of the support member; or,

[0024] The adjustment command is an adjustment command generated based on the driving status information to adjust the position of the support component.

[0025] Optionally, when an adjustment command characterizing the position of the adjustment support member in the width direction of the vehicle seat is received, changing the energization state of the magnetic adjustment structure includes:

[0026] When a first adjustment command is received from the left turn signal of the steering wheel, the energization state of the magnetic adjustment structure located on the right side of the vehicle seat is changed according to the first adjustment command, so that the support member of the seat wing on the right side of the vehicle seat moves from its current position toward the left side of the vehicle seat to the target position; or,

[0027] When the second adjustment command generated by the right turn signal of the steering wheel is received, the energization state of the electromagnetic adjustment structure located on the left side of the vehicle seat is controlled according to the second adjustment command, so that the support member of the seat wing located on the left side of the vehicle seat moves from the current position toward the right side of the vehicle seat to the target position.

[0028] When a steering wheel return signal is received, the support of the seat wing on the left side of the vehicle seat is moved to the left, or the support of the seat wing on the right side of the vehicle seat is moved to the right.

[0029] Optionally, the fixed part includes a first permanent magnet, and the movable part includes a second permanent magnet, wherein the magnetic poles of the first permanent magnet and the second permanent magnet are opposite in the width direction of the vehicle seat;

[0032] When an adjustment command characterizing the position of the adjustment support member in the width direction of the vehicle seat is received, changing the energization state of the magnetic adjustment structure includes:

[0033] When an adjustment command is received indicating the position of the adjustment support in the width direction of the vehicle seat, a preset current value is applied to the solenoid to move the second permanent magnet relative to the first permanent magnet in the width direction of the vehicle seat, thereby causing the support to move in the width direction of the vehicle seat.

[0034] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0035] In the seat side wing disclosed herein, the adjustment of the support member's position in the seat width direction is controlled by controlling the energization state of the magnetic adjustment structure. The magnetic force generated or lost the instant the energization state changes facilitates rapid adjustment of the support member's position, resulting in a fast response speed. Furthermore, no extra noise is generated during adjustment. This solves the problem of slow adjustment speed of mechanical and pneumatic methods in related technologies, which cannot meet the adjustment requirements of the seat side wing, and also solves the problem of loud noise from air pump adjustment. In addition, compared to the solution using multiple air pumps in related technologies, this also contributes to the weight reduction of the seat side wing and vehicle seat to a certain extent.

[0036] Furthermore, due to the rapid adjustment speed of the seat side wing provided in this disclosure, it is applicable not only to static adjustment of the seat side wing but also to dynamic adjustment. Static adjustment can be used to adjust the support to a comfortable seating position before driving. Dynamic adjustment can be used to adjust the support to a target position during vehicle driving. For example, when the vehicle is going through a sharp bend or making a sudden steering wheel turn in an emergency, the human body shifts off the seat due to the centrifugal force generated by inertia. At this time, the energization state of the magnetic adjustment module controlling the seat side wing on one side of the vehicle seat (the side opposite to the steering direction) can be changed, so that the support on that side quickly moves closer to the driver and passenger to provide support, making it safer and more comfortable for the occupants to pass through bends.

[0037] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0047] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0048] In this disclosure, unless otherwise stated, terms such as "left" and "right" are used in accordance with the left and right directions when the vehicle is in normal driving condition. The left and right direction of the vehicle seat 100, that is, the width direction of the vehicle seat 100, can be found in [reference needed]. Figure 1 "Inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, terms such as "first" and "second" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0049] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0050] Research has found that in mechanical transmission solutions of related technologies, the full-stroke adjustment speed of seat side wing adjustment is around 10 seconds, while pneumatic adjustment speed is generally around 5 seconds. These pneumatic adjustments are only suitable for static seat side wing adjustment, where the occupant feels the side wing is too wide or too narrow when seated, and manually adjusts the position of the side wing support to meet their comfort needs. They are not suitable for dynamic seat side wing adjustment. For example, when the vehicle is going through a sharp turn or making a sudden steering wheel maneuver in an emergency, the body shifts from the seat due to inertia. At this time, the seat side wing support cannot provide sufficient support due to the distance between itself and the occupant, and the support cannot adjust to the correct position within 0.5 seconds to provide adequate support.

[0051] To meet the dynamic adjustment requirements of the seat side wing, vehicles using this technology have optimized the second approach, such as increasing the number of air pumps to improve response speed, but this still only achieves a response time of 2-3 seconds. Furthermore, using multiple air pumps presents significant challenges for seat space arrangement, requiring the seats to be larger and thicker to accommodate more pumps. Additionally, as mentioned above, the excessive noise from the air pumps during inflation and deflation increases the noise level inside the vehicle and adds considerable weight, which is detrimental to lightweight design requirements. Moreover, vehicles using this technology also utilize the air spring pumps for side wing support, drawing air pipes from the vehicle's trunk and passing them through a series of pressure relief valves for adjusting the seat side wing airbags, improving the response speed to approximately 1.5 seconds. This technology improves the response speed of seat side wing adjustment, but it also places high demands on vehicle configuration, requiring air springs. This not only affects the lifespan of the air springs, but the extremely long air pipes also pose a significant challenge to interior space arrangement.

[0052] In view of this, such as Figures 1 to 4This disclosure provides a seat side wing 10, including a mounting member 11, a support member 12, and a magnetic adjustment structure 13. The mounting member 11 is used to connect to the seat body 20 of a vehicle seat 100, for example, the mounting member 11 is used to connect to the side panel 21 of the vehicle seat body 20. The support member 12 is used to provide lateral support for the driver and passenger. Foam or similar components may be provided on the support member to support the body of the driver and passenger. The magnetic adjustment structure 13 includes a fixed part 131 and a movable part 132. The fixed part 131 is connected to the mounting member 11, and the movable part 132 is connected to the support member 12. The movable part 132 is configured to move relative to the fixed part 131 in the width direction of the vehicle when the energized state of the magnetic adjustment structure 13 changes, for example, when the magnetic adjustment structure 13 changes between being energized and de-energized, or when the magnitude of the energized current changes, so as to adjust the position of the support member 12 in the width direction of the vehicle seat 100.

[0053] In the seat side wing 10 provided in this disclosure, the adjustment of the support member 12 in the seat width direction is controlled by controlling the energization state of the magnetic adjustment structure 13. That is, the magnetic adjustment structure 13 adjusts the position of the support member 12 in the width direction of the vehicle seat 100 through electronic control. The magnetic force generated or lost at the instant the energization state of the magnetic adjustment structure 13 changes facilitates rapid adjustment of the position of the support member 12, with a fast response speed, achieving adjustment of the seat side wing 10 position within 100ms. Furthermore, no extra noise is generated during adjustment. This solves the problem that the mechanical transmission and pneumatic adjustment methods in related technologies are too slow to meet the adjustment requirements of the seat side wing 10, and also solves the problem of loud noise from air pump adjustment. In addition, compared with the solution using multiple air pumps in related technologies, it also contributes to the weight reduction of the seat side wing 10 and the vehicle seat 100 to a certain extent.

[0054] Furthermore, because the seat side wing 10 provided in this disclosure has a fast adjustment speed, it can be applied not only to the static adjustment of the seat side wing 10, but also to the dynamic adjustment of the seat side wing 10. Static adjustment can be used to adjust the support member 12 to a support position that allows the human body to sit comfortably before driving. Dynamic adjustment can be used to adjust the support member 12 to a target position during vehicle driving. For example, when the vehicle is going through a sharp bend or when the steering wheel is turned sharply for emergency avoidance, the human body shifts off the seat due to the centrifugal force generated by inertia. At this time, the energization state of the magnetic adjustment module controlling one side of the vehicle seat 100 (the side opposite to the steering direction) can be changed to quickly bring the support member 12 on that side closer to the driver and passenger to provide support for the driver and passenger, making it safer and more comfortable for the occupants to pass through bends. Taking the scenario of the vehicle turning right as an example, when the driver and passengers shift to the left due to centrifugal force, the energization state of the magnetic adjustment structure 13 of the seat side wing 10 located on the left side of the vehicle seat 100 can be changed, so that the support member 12 of the seat side wing 10 on that side quickly moves closer to the driver and passengers, so as to provide support for the driver and passengers.

[0055] This disclosure does not limit the specific structure of the magnetic adjustment structure 13, as long as it can quickly adjust the position of the support member 12 in the width direction of the vehicle seat 100. Figures 2 to 4 As shown, in one embodiment of this disclosure, the fixed part 131 includes a first permanent magnet 1311, and the movable part 132 includes a second permanent magnet 1321. In the width direction of the vehicle seat 100, the magnetic poles of the first permanent magnet 1311 and the second permanent magnet 1321 are opposite. The magnetic force adjustment structure 13 also includes a solenoid coil 133. A first end of the solenoid coil 133 is connected to the first permanent magnet 1311, and a second end of the solenoid coil 133 is connected to the second permanent magnet 1321. The solenoid coil 133 is configured such that when a preset current value is applied, the second permanent magnet 1321 can move relative to the first permanent magnet in the width direction of the vehicle seat 100. In this embodiment, see [reference needed]. Figure 3 The diagram schematically illustrates the magnetic poles and magnetic fields of the first permanent magnet 1311 and the second permanent magnet 1321. Specifically, it shows the S1 and N1 poles of the first permanent magnet 1311 and the S2 and N2 poles of the second permanent magnet 1321, as shown. Figure 3 As shown, the position of the support 12 does not need adjustment. Before the solenoid coil 133 is energized, the first permanent magnet 1311 and the second permanent magnet 1321 generate a mutual attractive force F1 due to their opposite magnetic poles, causing the second permanent magnet 1321 to be in its initial position (the position with the smallest distance from the first permanent magnet 1311), for example, so that the second permanent magnet 1321 is close to the first permanent magnet 1311. Figure 3 The guide support column 134 is shown.

[0056] like Figure 4As shown, the S3 and N3 poles of the new magnetic field generated by the energized solenoid 133 are schematically illustrated. When a preset current value is applied to the solenoid 133, a new magnetic field is generated. The direction of this magnetic field is opposite to the direction of the magnetic field between the first permanent magnet 1311 and the second permanent magnet 1321. The repulsive force generated by the S3 pole of the energized solenoid 133 on the S2 pole of the second permanent magnet 1321 is generated, i.e., a repulsive force F2 is generated. When the repulsive force F2 is greater than F1, the second permanent magnet 1321 moves away from the first permanent magnet 1311 under the action of the repulsive force F2, and drives the support member 12 to move towards the side of the driver's body to move to the target position to apply a supporting force to the human body.

[0057] It is understandable that the specific value of F2 can be determined by the size of the preset current value, and the preset current value can be set as needed, as long as F2 is greater than F1.

[0058] The distance the second permanent magnet 1321 moves can be calibrated according to the unfolding angle of different seat side wings 10. The adjustment range of the support member 12 can be calibrated by the current magnitude and the distance between the first permanent magnet 1311 and the second permanent magnet 1321. When the second permanent magnet moves to the calibrated distance, the current magnitude can be adjusted so that F2 equals F1. At this time, the position of the second magnet remains fixed, the current magnitude remains constant, and the support member 12 is adjusted into place and held in the target position.

[0059] In order to provide support for the solenoid coil 133, such as Figure 2 As shown, the magnetic adjustment structure 13 may also include a guide support column 134, one end of which is connected to the mounting member 11, and the other end of which extends toward the support member 12. A solenoid coil 133 is sleeved on the guide support column 134. Besides using... Figures 2 to 4 The magnetic adjustment structure 13 shown in the embodiment can be adapted to other structures in other embodiments of this disclosure. For example, in another embodiment, the magnetic adjustment structure 13 can be an electromagnetic push rod, with the fixed part 131 and the movable part 132 being the stationary and moving iron cores of the electromagnetic push rod, respectively. The moving iron core has a push rod connected to the support member 12. By utilizing the attraction and release of the moving and stationary iron cores with push rods, the linear reciprocating motion of the push rod can be achieved, thereby quickly adjusting the position of the support member 12 in the vehicle width direction. The electromagnetic push rod operates crisply and rapidly, with an extension time of less than 0.05s and a reset time of less than 0.05s.

[0060] To achieve precise control over the position of the support 12, optionally, such as Figure 1 and Figure 2As shown, the seat side wing 10 may further include a controller and a sensor 14. The sensor 14 is disposed on the mounting member 11 and is used to detect the distance between the support member 12 and the mounting member 11 in the width direction of the vehicle seat 100. The controller is used to change the energization state of the magnetic adjustment structure 13 according to the detection result of the sensor 14, that is, to change the energized / de-energized state of the magnetic adjustment structure 13, or to change the magnitude of the energized current, for example, in such a case... Figures 2 to 4 In the illustrated embodiment, the energized / de-energized state of the solenoid 133 of the magnetic adjustment structure 13, or the magnitude of the energized current, is changed to adjust the position of the support member 12 in the width direction of the vehicle seat 100. Based on this, the sensor 14, in conjunction with the controller, facilitates precise adjustment of the position of the support member 12, improving the comfort and safety of the support member 12 in supporting the human body.

[0061] In such Figure 4 In the embodiment shown, when adjusting the position of the support member 12, after the sensor 14 detects that the support member 12 has been adjusted to the correct position, the controller can control the magnitude of the current flowing through the solenoid coil 133 so that F2 equals F1, thereby keeping the support member 12 in the target position.

[0062] Here, the controller can be an existing controller in the vehicle, such as the vehicle's domain controller, or it can be a controller separately configured for adjusting the seat side wing 10. This disclosure does not limit it in this way.

[0063] Furthermore, the specific type of sensor 14 disclosed herein is not limited, as long as it can accurately detect the distance between the support member 12 and the mounting member 11. Optionally, in one embodiment of this disclosure, the sensor 14 is a Hall sensor. Hall sensors have advantages such as sensitivity to magnetic fields, simple structure, small size, large output voltage variation, and long service life, making them suitable for adjusting the distance between the support member 12 and the mounting member 11 of the seat side wing 10. In other embodiments of this disclosure, the sensor 14 can be a laser sensor, etc.

[0064] In this disclosure, such as Figures 2 to 4 As shown, both the mounting member 11 and the support member 12 can be plate-shaped. The mounting member 11 and the support member 12 are spaced apart and arranged opposite each other in the width direction of the vehicle seat 100. When detecting the distance between the mounting member 11 and the support member 12, the distance between the surfaces of the mounting member 11 and the support member 12 facing each other can be detected. The mounting member 11 and the support member 12 are plate-shaped, and the structure is simple.

[0065] like Figures 2 to 4As shown, there can be multiple magnetic adjustment structures 13. When the mounting member 11 and the support member 12 are elongated plate-like pieces, the multiple magnetic adjustment structures 13 are arranged at intervals along the extending direction of the support member 12 and the mounting member 11. In this way, the multiple magnetic adjustment structures 13 facilitate the smooth movement of the support member 12 in the width direction of the vehicle seat 100 and help to provide sufficient support force.

[0066] According to another aspect of this disclosure, a vehicle seat 100 is provided, which includes a seat body 20 and the aforementioned seat side wings 10. The number of seat side wings 10 is at least two, and seat side wings 10 connected to the seat body 20 are respectively provided on both sides of the vehicle seat 100 in the width direction.

[0067] According to another aspect of this disclosure, a vehicle is provided that includes the aforementioned vehicle seat 100.

[0068] According to another aspect of this disclosure, a method for adjusting seat side wings is provided, which can be applied to the seat side wings 10 described above, i.e., as... Figures 1 to 4 As shown, the seat side wing 10 includes a mounting member 11, a support member 12, and a magnetic adjustment structure 13. The mounting member 11 is connected to the body of the vehicle seat 100, the support member 12 provides lateral support for the driver and passengers, and the magnetic adjustment structure 13 includes a fixed part 131 and a movable part 132. The fixed part 131 is connected to the mounting member 11, and the movable part 132 is connected to the support member 12. The movable part 132 is configured to move relative to the fixed part 131 when the energized state of the magnetic adjustment structure 13 changes. The method includes:

[0069] When an adjustment command is received indicating the position of the adjustment support 12 in the width direction of the vehicle seat 100, the energization state of the magnetic adjustment structure 13 is changed, that is, the energized / de-energized state of the magnetic adjustment structure 13 is changed, or the magnitude of the energized current is changed, for example, in the case of... Figures 2 to 4 In the illustrated embodiment, changing the energized / de-energized state of the solenoid 133 of the magnetic adjustment structure 13, or changing the magnitude of the energized current, controls the rapid movement of the fixing part 131 in the width direction of the vehicle seat 100, thereby driving the support member 12 to move rapidly in the width direction of the vehicle seat 100. Thus, the magnetic force generated or lost by the magnetic adjustment structure 13 at the moment of change of energization facilitates rapid adjustment of the position of the support member 12.

[0070] by Figures 2 to 4Taking the illustrated embodiment as an example, when an adjustment command is received indicating the position of the adjustment support 12 in the width direction of the vehicle seat 100, that is, when it is necessary to adjust the position of the support 12 in the width direction of the vehicle seat 100, if the first permanent magnet 1311 and the second permanent magnet 1321 are in their initial positions with the smallest interval, and it is necessary to move the support 12 toward the human body, the solenoid coil 133 can be energized, and the support 12 can be moved quickly toward the human body. If the solenoid coil 133 is already energized, the current can be reduced or the solenoid coil 133 can be de-energized, thus allowing the support 12 to be moved quickly away from the human body along the width direction of the vehicle seat 100.

[0071] As discussed above, the seat side wing 10 provided in this disclosure has a fast adjustment speed, making it suitable not only for static adjustment but also for dynamic adjustment. Static adjustment can be used to adjust the support member 12 to a comfortable seating position before driving. Dynamic adjustment can be used to adjust the support member 12 to a target position while driving.

[0072] In an embodiment where sensor 14 is provided, the method further includes:

[0073] When the sensor 14 receives a positioning signal, the energizing current of the magnetic adjustment structure 13 is maintained at a preset threshold to keep the support member 12 in the target position. By setting the sensor 14, it is possible to achieve precise adjustment of the position of the support member 12, thereby improving the comfort and safety of the support member 12 in supporting the human body.

[0074] The preset threshold for the energizing current is the current value that makes F2 equal to F1.

[0075] It is understandable that here, the adjustment command can be an adjustment command for the position of the adjustment support 12 generated by the operator. That is, the adjustment command can be responsive to the driver or passenger. For example, a switch can be provided on the seat. When it is necessary to adjust the seat side wing 10, especially when the seat side wing 10 is statically adjusted, the adjustment command can come from the driver or passenger's operation of the switch.

[0076] The adjustment command can be an adjustment command for adjusting the position of the support member 12 generated based on driving status information. For example, based on the vehicle's turning information or collision information, the position of the support member 12 on one or both sides of the vehicle seat 100 can be adjusted accordingly. Especially when dynamically adjusting the seat side wing 10, the adjustment command is generated based on driving status information, which is conducive to quickly adjusting the position of the support member 12 as needed.

[0077] exist Figures 1 to 4In the illustrated embodiment, when an adjustment command characterizing the position of the adjustment support 12 in the width direction of the vehicle seat 100 is received, changing the energization state of the magnetic adjustment structure 13 may include:

[0078] When a first adjustment command is received from the left turn signal of the steering wheel, the energization state of the electromagnetic adjustment structure of the seat side wing 10 located on the right side of the vehicle seat 100 is changed according to the first adjustment command, so that the support member 12 of the seat side wing 10 located on the right side of the vehicle seat 100 moves from its current position toward the left side of the vehicle seat 100 to the target position; or,

[0079] When the second adjustment command generated by the right turn signal of the steering wheel is received, the energization state of the electromagnetic adjustment structure of the seat wing 10 located on the left side of the vehicle seat 100 is changed according to the second adjustment command, so that the support member 12 of the seat wing 10 located on the left side of the vehicle seat 100 moves from the current position toward the right side of the vehicle seat 100 to the target position.

[0080] When a steering wheel return signal is received, the support member 12 of the seat side wing 10 located on the right side of the vehicle seat 100 is controlled to move to the right to return to the initial position or the position when the first adjustment command was received, thereby achieving the return to the original position. Alternatively, the support member 12 of the seat side wing 10 located on the left side of the vehicle seat 100 is controlled to move to the left to return to the initial position or the position when the second adjustment command was received, thereby achieving the return to the original position.

[0081] In this way, the seat side wing 10 on the corresponding side of the vehicle seat 100 can be adjusted in time according to the steering wheel, so as to provide timely support for the human body that is shifting.

[0082] It is understandable that, in addition to the steering wheel's turning status, vehicle steering information can also be represented by other information. For example, an additional angle sensor 14 can be used to detect the vehicle's steering status, and the vehicle's steering information can be determined based on the detection results of the angle sensor 14.

[0083] In addition to dynamically adjusting the seat side wing 10 when the vehicle is turning, the seat side wing 10 on the corresponding side of the vehicle seat 100 can also be dynamically and quickly adjusted in the event of a collision, especially a side collision, so that the support member 12 on the corresponding side can support the human body.

[0084] The following section, in conjunction with the accompanying drawings, details the specific process of static and dynamic adjustment of the seat side wings 10.

[0085] See Figure 5During static adjustment, the support adjustment switch can be turned on, sending a side wing support switch signal to the domain controller. Simultaneously, the domain controller sends a command to the seat side wings 10 on both sides of the vehicle seat 100 (left and right side wings), energizing the solenoid 133 and initiating movement of the movable part 132 (second permanent magnet 1321). When the Hall sensor 14 used for distance calibration measures that the distance has reached the calibration value, the current remains constant. At this point, the support members 12 of the seat side wings 10 on both sides of the vehicle seat 100 are adjusted into position. Afterward, the switch can be turned off, and the domain controller simultaneously sends a command to the seat side wings 10 on both sides of the vehicle seat 100, de-energizing the solenoid 133, returning the movable part 132 to its original position, and disabling the seat side wing support function.

[0086] See Figure 6 During dynamic adjustment, the steering wheel signal can be transmitted to the domain controller. If a left turn signal is received, the domain controller sends a command to the seat wing 10 located on the right side of the vehicle seat 100, energizing the solenoid 133 on the right side. The movable part 132 (second permanent magnet 1321) begins to move. After the Hall sensor 14 measures that the distance has reached the calibration value, the current remains constant, and the support member 12 on the right side is adjusted into place. When the steering wheel returns to center, the domain controller sends a command to the seat wing 10 located on the right side of the vehicle seat 100, de-energizing the solenoid 133, returning the movable part 132 to its original position, and deactivating the wing support function. If a right turn signal is received, the domain controller sends a command to the seat wing 10 located on the left side of the vehicle seat 100, energizing the solenoid 133 on the left side. The movable part 132 (second permanent magnet 1321) begins to move. After the Hall sensor 14 measures that the distance has reached the calibration value, the current remains constant, and the support member 12 on the left side is adjusted into place. When the steering wheel is returned to center, the domain controller sends a command to the seat wing 10 located on the left side of the vehicle seat 100, the solenoid 133 is de-energized, the movable part 132 returns to its original position, and the wing support function is turned off.
