Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive interior technology, and in particular discloses a seat that can automatically rotate to provide support and a method for controlling the operation of the seat. Background Technology
[0002] Currently, car seats typically provide support to occupants by increasing the wrapping effect of the side wings, commonly using active side wing airbags. However, this method cannot adjust the support based on actual vehicle speed, steering, or other factors during driving.
[0003] Since it is impossible to apply a compression signal to the side wings based on vehicle speed and steering to make the seat rotate at a corresponding angle to increase support for the occupants, there is an urgent need for a seat that can automatically rotate to provide support and a method for controlling the operation of the seat. Summary of the Invention
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a seat that can automatically rotate to provide support and a method for controlling the operation of the seat.
[0005] To achieve the above objectives, the present invention provides a seat that can automatically rotate to provide support. The seat includes a seat cushion and a backrest that is rotatably disposed relative to the seat cushion. Both the seat cushion and the backrest are provided with protrusions, which are disposed on both sides of the seat cushion and / or the backrest. Pressure sensors are mounted on the protrusions. Through the protrusion design on the seat cushion and the backrest, support can be provided for both sides of the waist / hips, which helps to distribute body pressure and reduce fatigue caused by long-term sitting.
[0006] Preferably, the seat cushion is provided with a connecting component, which is used to mount the seat cushion onto an external long slide rail assembly. The seat cushion is then positioned relative to the vehicle via the external long slide rail assembly. The long slide rail assembly provides a large adjustment range, allowing the seat cushion to move back and forth to meet the personalized needs of different passengers or drivers for legroom and driving posture. The connection between the seat cushion and the long slide rail assembly via the connecting component reduces direct contact and friction with the vehicle floor or other components, which helps to extend the service life of the seat.
[0007] Preferably, the connecting assembly includes an upper turntable component disposed on the seat cushion and a lower turntable component disposed on a long slide rail assembly. The upper turntable component and the lower turntable component are rotatably disposed. The lower turntable component / long slide rail assembly is equipped with a drive component for driving the upper turntable component to rotate relative to the lower turntable component. Driven by the drive component, the upper turntable component can rotate at multiple angles relative to the lower turntable component, thereby realizing multi-directional adjustment of the seat cushion on the horizontal plane. This adjustment method is more flexible than the traditional linear sliding and can meet more diverse riding needs. The introduction of the drive component (servo motor) makes the seat adjustment process more precise and controllable. By controlling the working state of the drive component, fine adjustments to the seat position or angle can be made, improving riding comfort.
[0008] Preferably, an operation control method for a seat that can automatically rotate to provide support includes the following steps:
[0009] S1: Detect whether the seat side wings are being squeezed and acquire pressure signals;
[0010] S2: Detect the vehicle's driving condition when the seat is compressed;
[0011] S3: When the vehicle's driving status meets the preset pressure signal, vehicle speed, and steering angle, the seat rotates in the opposite direction.
[0012] Preferably, pressure sensors are installed on both sides of the seat cushion and / or both sides of the seat back. The pressure sensors are electrically connected to the control system to acquire pressure signals from the human waist and hips and transmit them to the control system. When the vehicle is moving or braking suddenly, the passenger's body may move due to inertia, resulting in an unstable sitting posture. At this time, the pressure sensors can quickly detect the changes in the passenger's body and adjust the seat support force through the control system to provide more stable support for the passenger, thereby improving driving safety. The combination of pressure sensors and control system realizes intelligent control of the seat. Through real-time monitoring and data analysis, the control system can automatically complete the seat adjustment task without the need for manual operation by the passenger. This intelligent control not only improves the convenience of riding, but also reduces the difficulty of operation and the error rate.
[0013] Preferably, the pressure signals of the seat side wings are acquired and collected via pressure sensors. When the pressure signal value collected by one pressure sensor is greater than that collected by the other pressure sensor, the control system receives and uses the larger pressure signal value that has reached the threshold, controls the system, and acquires the vehicle speed. When the pressure signal value collected by the pressure sensor on one side of the seat wing is significantly greater than that on the other side, this usually means that the driver or passenger's body may be tilting / the vehicle is turning. During this process, the pressure sensor transmits the collected pressure signal to the control system, which can then rotate the seat to provide more stable support for the driver.
[0014] Preferably, the vehicle speed sensor is electrically connected to the control system to obtain the vehicle speed. When the vehicle speed is not less than 30 km / h, the speed information collected by the vehicle speed sensor is transmitted to the control system to determine the vehicle steering angle. When the seat side wing is compressed, the system can detect the pressure signal and perceive the changes in the body posture of the passenger or driver in real time. Combined with the vehicle speed information, when the vehicle speed reaches or exceeds 30 km / h and the steering angle meets the preset conditions, the seat automatically rotates in the opposite direction to provide more stable support for the passenger or driver, reducing safety hazards caused by body tilting or imbalance. Under high-speed driving and complex road conditions, the automatic rotation function of the seat can help the passenger or driver maintain body balance, reduce body swaying caused by vehicle bumps or steering, and make the driving process more stable and smooth.
[0015] Preferably, the seat's reverse rotation angle is 0-8°. An excessively large rotation angle may cause discomfort or loss of balance for passengers or drivers. Limiting the rotation angle to within 0-8° can effectively avoid this situation, ensuring that the seat's support adjustment is both effective and comfortable. At the same time, the 0-8° rotation angle range is relatively universal and can adapt to the needs of many vehicle models and interior layouts. Furthermore, the reverse rotation of the seat within the 0-8° range can enhance the lateral support for passengers or drivers.
[0016] Preferably, when the vehicle speed is between 30 and 45 km / h and the vehicle is turning, the seat rotates backward 0-3°; when the vehicle speed is between 45 and 60 km / h and the vehicle is turning, the seat rotates backward 3-6°; and when the vehicle speed is greater than 60 km / h and the vehicle is turning, the seat rotates backward 6-8°. The vehicle speed is subdivided into three ranges: 30-45 km / h, 45-60 km / h, and greater than 60 km / h. Different seat rotation angle ranges are set for each range. This fine-tuning can more accurately adapt to the driving needs at different speeds, providing a more personalized support experience. Within each speed range, the seat's backward rotation angle has a clear upper and lower limit. This precise control ensures that the seat support adjustment is neither excessive nor insufficient, achieving the best support effect. By increasing the seat's backward rotation angle, additional lateral support is provided for passengers or drivers, reducing body tilt and maintaining body balance.
[0017] Preferably, the seat angle automatically resets after steering based on the compression signal, vehicle speed, and steering angle. It can automatically adjust the seat angle according to the body posture and driving status of the passenger or driver, which helps reduce fatigue caused by long-term driving and improves driving comfort and enjoyment. The seat can maintain a smooth transition during the automatic reset process, avoiding sudden movement or shaking that may cause discomfort to the passenger or driver, thus helping to improve the overall driving experience.
[0018] The beneficial effects of this invention are as follows: By monitoring the pressure changes of the seat side wings in real time through intelligent sensors, the system can instantly perceive the passenger's body dynamics and posture. When the passenger is turning, accelerating rapidly, or braking suddenly, the body may tilt due to inertia, at which point the pressure on the side wings increases. The sensors can quickly capture this change. In addition, by combining the vehicle's driving status (such as vehicle speed and steering angle) for comprehensive judgment, the system can accurately identify the specific situation in which the passenger needs additional support, such as sharp turns or emergency braking at high speeds. Based on the real-time data and analysis results of the first two steps, when the system determines that the passenger needs additional support to maintain body balance, the seat can automatically rotate in the opposite direction to provide a more suitable support angle. This dynamic adjustment not only helps to reduce the passenger's discomfort under complex driving conditions but also improves driving safety and avoids potential dangers caused by the passenger losing control of their body.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0026] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.
[0027] Please see Figures 1 to 3As shown, a seat that can automatically rotate to provide support is provided. The seat 2 includes a seat cushion and a backrest that is rotatably disposed relative to the seat cushion. Both the seat cushion and the backrest are provided with protrusions, which are disposed on both sides of the seat cushion and / or the backrest. Pressure sensors are mounted on the protrusions. Through the protrusion design on the seat cushion and the backrest, support can be provided for both sides of the waist / hips, which helps to distribute body pressure and reduce fatigue caused by long-term sitting.
[0028] Specifically, the seat cushion is equipped with a connecting component, which is used to mount the seat cushion onto the external long slide rail assembly 5. The seat cushion is then positioned relative to the vehicle via the external long slide rail assembly 5. The long slide rail assembly 5 provides a large adjustment range, allowing the seat cushion to move back and forth to meet the personalized needs of different passengers or drivers for legroom and driving posture. The seat cushion is connected to the long slide rail assembly 5 via the connecting component, which reduces direct contact and friction with the vehicle floor or other components, thus helping to extend the service life of the seat 2.
[0029] Specifically, the connecting components include an upper turntable component 3 mounted on the seat cushion and a lower turntable component 4 mounted on a long slide rail assembly 5. The upper turntable component 3 and the lower turntable component 4 are rotatably mounted. The lower turntable component 4 / long slide rail assembly 5 is equipped with a drive component to drive the upper turntable component 3 to rotate relative to the lower turntable component 4. Driven by the drive component, the upper turntable component 3 can rotate at multiple angles relative to the lower turntable component 4, thereby realizing multi-directional adjustment of the seat cushion on the horizontal plane. This adjustment method is more flexible than the traditional linear sliding and can meet more diverse riding needs. The introduction of the drive component (servo motor) makes the adjustment process of the seat 2 more precise and controllable. By controlling the working state of the drive component, the position or angle of the seat 2 can be finely adjusted, improving the riding comfort.
[0030] For details, please refer to Figure 3 In this embodiment, from top to bottom, there are seat 2, upper turntable component 3, lower turntable component 4 and long slide rail assembly 5. Seat 2 and upper turntable component 3 are fixedly installed, upper turntable component 3 and lower turntable component 4 are rotatably installed, lower turntable component 4 and long slide rail assembly 5 are slidably installed, and lower turntable component 4 and long slide rail assembly 5 are slidably installed via other driving components.
[0031] Specifically, an operation control method for a seat that can automatically rotate to provide support includes the following steps:
[0032] S1: Detect whether the two side wings of the seat are being squeezed and obtain pressure signals;
[0033] S2: Detect the vehicle's driving status when seat 2 is compressed;
[0034] S3: When the vehicle's driving status meets the preset pressure signal, vehicle speed, and steering angle, the seat 2 rotates in the opposite direction.
[0035] Specifically, by using intelligent sensors to monitor pressure changes on the side wings of seat 2 in real time, the system can instantly perceive the passenger's body dynamics and posture. When a passenger is turning, accelerating rapidly, or braking suddenly, their body may tilt due to inertia, increasing the pressure on the side wings. The sensors can quickly capture this change. In addition, by combining the vehicle's driving status (such as speed and steering angle) for comprehensive judgment, the system can accurately identify the specific situations in which the passenger needs additional support, such as sharp turns or emergency braking at high speeds. Based on the real-time data and analysis results of the first two steps, when the system determines that the passenger needs additional support to maintain body balance, seat 2 can automatically rotate in the opposite direction to provide a more suitable support angle. This dynamic adjustment not only helps to reduce passenger discomfort under complex driving conditions but also improves driving safety and avoids potential dangers caused by the passenger losing control of their body.
[0036] Specifically, pressure sensors 1 are installed on both sides of the seat cushion and / or both sides of the backrest of seat 2. Pressure sensors 1 are electrically connected to the control system to acquire pressure signals from the human waist and hips and transmit them to the control system. During vehicle operation, especially during sharp turns, rapid acceleration, or sudden braking, the passenger's body may move due to inertia, resulting in an unstable sitting posture. At this time, pressure sensors 1 can quickly sense the changes in the passenger's body and adjust the support force of seat 2 through the control system to provide more stable support for the passenger, thereby improving driving safety. The combination of pressure sensors 1 and the control system realizes intelligent control of seat 2. Through real-time monitoring and data analysis, the control system can automatically complete the adjustment task of seat 2 without the need for manual operation by the passenger. This intelligent control not only improves the convenience of riding but also reduces the difficulty of operation and the error rate.
[0037] Specifically, the control system can be installed on seat 2 / vehicle.
[0038] Specifically, the pressure signal of the side wing of the seat 2 is acquired and collected by the pressure sensor 1. When the pressure signal value collected by the pressure sensor 1 on one side is significantly greater than the pressure signal value collected by the pressure sensor 1 on the other side, it can be personalized according to the user's body size. The control system receives and uses the larger pressure signal value that has reached the threshold, controls the system and obtains the vehicle speed. When the pressure signal value collected by the pressure sensor 1 on one side of the seat 2 is significantly greater than that on the other side, this usually means that the driver or passenger's body may be tilting / the vehicle is turning. During this process, the pressure sensor 1 transmits the collected pressure signal to the control system, which can then rotate the seat 2 to provide more stable support for the driver.
[0039] Specifically, the vehicle speed sensor is electrically connected to the control system to obtain the vehicle's speed. When the vehicle speed is not less than 30 km / h, the speed information collected by the sensor is transmitted to the control system to determine the vehicle's steering angle. When the side wing of seat 2 is compressed, the system can detect the pressure signal and perceive changes in the body posture of the passenger or driver in real time. Combined with the vehicle speed information, when the vehicle speed reaches or exceeds 30 km / h and the steering angle meets the preset conditions, seat 2 automatically rotates in the opposite direction to provide more stable support for the passenger or driver, reducing safety hazards caused by body tilting or imbalance. Under high-speed driving and complex road conditions, the automatic rotation function of seat 2 can help the passenger or driver maintain body balance, reduce body swaying caused by vehicle bumps or steering, and make the driving process more stable and smooth.
[0040] Specifically, when the vehicle's steering angle is not 0°, seat 2 rotates in the opposite direction. The rotation angle of seat 2 is 0-8°. Excessive rotation angle may cause discomfort or loss of balance for passengers or drivers. Limiting the rotation angle to within 0-8° can effectively avoid this situation, ensuring that the support adjustment of seat 2 is both effective and comfortable. At the same time, the rotation angle range of 0-8° is relatively universal and can adapt to the needs of many vehicle models and interior layouts. Furthermore, the reverse rotation of seat 2 within the 0-8° range can enhance the lateral support for passengers or drivers.
[0041] Specifically, when the vehicle speed is between 30 and 45 km / h and the vehicle is turning, seat 2 rotates 0-3° in the reverse direction; when the vehicle speed is between 45 and 60 km / h and the vehicle is turning, seat 2 rotates 3-6° in the reverse direction; and when the vehicle speed is greater than 60 km / h and the vehicle is turning, seat 2 rotates 6-8° in the reverse direction. The vehicle speed is subdivided into three ranges: 30-45 km / h, 45-60 km / h, and greater than 60 km / h. Different rotation angle ranges of seat 2 are set for different ranges. This fine adjustment can more accurately adapt to the driving needs at different speeds and provide a more personalized support experience. Within each speed range, the reverse rotation angle of seat 2 has a clear upper and lower limit. This precise control can ensure that the support adjustment of seat 2 is neither excessive nor insufficient, achieving the best support effect. By increasing the reverse rotation angle of seat 2, additional lateral support is provided for passengers or drivers, reducing body tilt and maintaining body balance.
[0042] Specifically, within the corresponding range, when the vehicle speed is constant, the larger the steering angle, the greater the reverse rotation angle of seat 2.
[0043] Specifically, X: the threshold of the pressure signal intensity level (the specific value is unknown, but it is assumed to have been determined experimentally); Y: the threshold of the steering angle (e.g., 5° to 15°); vehicle speed ranges: range 1: 30KM / H≤v<45KM / H, range 2: 45KM / H≤v<60KM / H, range 3: v≥60KM / H;
[0044] If (pressure signal strength level == X) and (vehicle speed is in range 1 and steering angle >= Y), then the rotation angle = 0-3°;
[0045] If (pressure signal strength level == X) and (vehicle speed is in interval 2 and steering angle >= Y), then the rotation angle = 3-6°;
[0046] If (pressure signal strength level == X) and (vehicle speed is in range 3 and steering angle >= Y), then the rotation angle = 6-8°;
[0047] Otherwise, the rotation angle is 0° (i.e., the current angle is maintained and no rotation is performed).
[0048] Specifically, the pressure signal strength level X needs to be set according to the user's body size.
[0049] Specifically, after steering, the seat 2 automatically resets its angle based on the compression signal, vehicle speed, and steering angle. It can automatically adjust the seat 2 angle according to the body posture and driving state of the passenger or driver, which helps reduce fatigue caused by long-term driving and improves driving comfort and enjoyment. The seat 2 can maintain a smooth transition during the automatic reset process, avoiding sudden movement or shaking that may cause discomfort to the passenger or driver, thus helping to improve the overall driving experience.
[0050] Specifically, the automatic reset speed of the seat angle is directly proportional to the reset speed of the steering angle.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
