Description

Technical Field

[0001] The invention relates to the technical field of automobile interior decoration, and in particular discloses a seat capable of automatically rotating to provide support and an operation control method of the seat. Background Art

[0002] Currently, car seats generally provide support to passengers by increasing the wrapping of the side wings. The most common type is active side wing airbag support. This method cannot adjust the support according to the actual vehicle speed, steering and other factors during driving.

[0003] That is, it is impossible to apply a squeezing signal to the side wings according to the vehicle speed and steering, so that the seat can be rotated to a corresponding angle, thereby increasing the support for the occupants through the angle rotation. Therefore, there is an urgent need for a seat that can automatically rotate to provide support and a seat operation control method. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a seat that can automatically rotate to provide support and a method for operating and controlling the seat.

[0005] To achieve the above-mentioned purpose, the present invention provides a seat that can automatically rotate to provide support, the seat includes a cushion portion and a backrest portion rotatable relative to the cushion portion, both the cushion portion and the backrest portion are provided with protrusions, the protrusions are provided on both sides of the cushion portion and / or the backrest portion, pressure sensors are installed on the protrusions, and through the protrusion design on the cushion portion and the backrest portion, support can be provided on both sides of the waist / hips, which helps to disperse body pressure and reduce fatigue caused by long-term riding.

[0006] Preferably, a connecting assembly is provided on the seat cushion portion, and the seat cushion portion is mounted on an external long slide rail assembly via the connecting assembly. The seat cushion portion is movable relative to the vehicle via the external long slide rail assembly. The long slide rail assembly provides a larger adjustment range, so that the seat cushion portion can move forward and backward to meet the personalized needs of different passengers or drivers for leg space and driving posture. The seat cushion portion is connected to the long slide rail assembly through the connecting assembly, which reduces direct contact and friction with the vehicle body floor or other components, and helps to extend the service life of the seat.

[0007] Preferably, the connecting assembly includes an upper turntable component arranged on the seat cushion part and a lower turntable component on the long slide rail assembly. The upper turntable component and the lower turntable component are rotatably arranged, and a driving member for driving the upper turntable component to rotate relative to the lower turntable component is installed on the lower turntable component / long slide rail assembly. The upper turntable component can be rotated at multiple angles relative to the lower turntable component by the driving member, thereby realizing multi-directional adjustment of the seat cushion part on the horizontal plane. This adjustment method is more flexible than traditional linear sliding and can meet more diverse riding needs. The introduction of the driving member (servo motor) makes the seat adjustment process more precise and controllable. By controlling the working state of the driving member, fine-tuning of the seat position or angle can be achieved, thereby improving riding comfort.

[0008] Preferably, a method for operating and controlling a seat that can automatically rotate to provide support comprises the following steps:

[0009] S1: Detect whether the seat side wings are squeezed and obtain pressure signals;

[0010] S2: Detecting the driving state of the vehicle with the seat squeezed;

[0011] S3: When the vehicle driving state meets the preset pressure signal, vehicle speed and steering angle, the seat is rotated in the opposite direction.

[0012] Preferably, pressure sensors are installed on both sides of the seat cushion and / or both sides of the seat backrest. The pressure sensors are electrically connected to the control system to obtain pressure signals on the waist and buttocks of the human body and transmit them to the control system. When the vehicle is driving or braking suddenly, the passenger's body may move due to inertia, resulting in an unstable sitting posture. At this time, the pressure sensor can quickly sense the changes in the passenger's body and adjust the support force of the seat through the control system to provide the passenger with more stable support, thereby improving driving safety. The combination of the pressure sensor and the control system realizes the intelligent control of the seat. Through real-time monitoring and data analysis, the control system can automatically complete the seat adjustment task without 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 signal of the seat wing is acquired and collected via a pressure sensor. When the pressure signal value collected by the pressure sensor on one side is greater than the pressure signal value collected by the pressure sensor on the other side, the control system receives and uses the larger pressure signal value that has reached the threshold, and the control system acquires the vehicle's driving 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 have tilted. During the vehicle's steering process, the pressure sensor transmits the collected pressure signal to the control system, and the control system 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 30KM / H, the speed information collected by the speed sensor is transmitted to the control system to judge the steering angle of the vehicle. When the side wings of the seat are squeezed, the system can sense the changes in the body posture of the passenger or driver in real time by detecting the pressure signal. Combined with the vehicle speed information, when the vehicle speed reaches or exceeds 30KM / 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 the safety hazards caused by body tilt or imbalance. Under high-speed driving and complex road conditions, the automatic rotation function of the seat can assist the passenger or driver to maintain body balance, reduce the body shaking caused by vehicle bumps or steering, and make the driving process more stable and smooth.

[0015] Preferably, the reverse rotation angle of the seat is 0-8°. Too large a rotation angle may cause the passenger or driver to feel uncomfortable or lose balance. Limiting the rotation angle within 0-8° can effectively avoid this situation and ensure that the seat support adjustment is both effective and comfortable. At the same time, the rotation angle range of 0-8° is relatively universal and can meet the needs of more vehicle models and interior layouts. The reverse rotation of the seat within the range of 0-8° can enhance the lateral support for the passenger or driver.

[0016] Preferably, when the vehicle speed is between 30-45KM / H and the vehicle is turning, the seat rotates 0-3° in the opposite direction; when the vehicle speed is between 45-60KM / H and the vehicle is turning, the seat rotates 3-6° in the opposite direction; when the vehicle speed is greater than 60KM / H and the vehicle is turning, the seat rotates 6-8° in the opposite direction. The vehicle speed is subdivided into three intervals: 30-45KM / H, 45-60KM / H and greater than 60KM / H, and different seat rotation angle ranges are set for different intervals. This refined adjustment can more accurately adapt to driving needs at different vehicle speeds and provide a more personalized support experience. In each speed range, the reverse rotation angle of the seat has clear upper and lower limits. This precise control can ensure that the seat support adjustment is neither excessive nor insufficient, and achieves the best support effect. By increasing the reverse rotation angle of the seat, additional lateral support is provided to passengers or drivers, reducing body tilt and maintaining body balance.

[0017] Preferably, the seat can automatically reset its angle according to the squeeze signal, vehicle speed and steering angle after turning, and can automatically adjust the seat angle according to the body posture and driving status of the passenger or driver, which helps to reduce fatigue caused by long-term driving and improve driving comfort and pleasure. The seat can maintain a smooth transition during the automatic reset process to avoid sudden movement or shaking that may cause discomfort to the passengers or drivers, which helps to improve the overall driving experience.

[0018] The beneficial effects of the present invention are as follows: by using intelligent sensors to monitor the pressure changes on the seat flanks in real time, the passenger's body dynamics and posture can be instantly sensed. When the passenger turns, accelerates suddenly or brakes suddenly, the body may tilt due to inertia. At this time, the pressure on the flanks increases, and the sensor can quickly capture this change. In addition, a comprehensive judgment is made based on the vehicle's driving status (such as vehicle speed, steering angle), and specific situations in which the passenger needs additional support can be accurately identified, 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 discomfort of passengers under complex driving conditions, but also improves driving safety and avoids potential dangers caused by the passenger's loss of control of the body.

[0027] See also Figures 1 to 3As shown, a seat that can automatically rotate to provide support, the seat 2 includes a cushion portion and a backrest portion that is rotatable relative to the cushion portion, both the cushion portion and the backrest portion are provided with protrusions, the protrusions are provided on both sides of the cushion portion and / or the backrest portion, and pressure sensors are installed on the protrusions. Through the protrusion design on the cushion portion and the backrest portion, support can be provided on both sides of the waist / hips, which helps to disperse body pressure and reduce fatigue caused by long-term riding.

[0028] Specifically, a connecting assembly is provided on the seat cushion portion, and the seat cushion portion is installed on the external long slide rail assembly 5 via the connecting assembly. The seat cushion portion is movable relative to the vehicle via the external long slide rail assembly 5. The long slide rail assembly 5 provides a large adjustment range, so that the seat cushion portion can move forward and backward to meet the personalized needs of different passengers or drivers for leg space and driving posture. The seat cushion portion is connected to the long slide rail assembly 5 through the connecting assembly, which reduces direct contact and friction with the vehicle body floor or other components, and helps to extend the service life of the seat 2.

[0029] Specifically, the connecting assembly includes a turntable upper component 3 arranged on the seat cushion part and a turntable lower component 4 on the long slide rail assembly 5. The turntable upper component 3 and the turntable lower component 4 are rotatably arranged. The turntable lower component 4 / long slide rail assembly 5 is equipped with a driving member for driving the turntable upper component 3 to rotate relative to the turntable lower component 4. Through the drive of the driving member, the turntable upper component 3 can be rotated at multiple angles relative to the turntable lower component 4, thereby realizing multi-directional adjustment of the seat cushion part on the horizontal plane. This adjustment method is more flexible than traditional linear sliding and can meet more diverse riding needs. The introduction of the driving member (servo motor) makes the adjustment process of the seat 2 more precise and controllable. By controlling the working state of the driving member, the position or angle of the seat 2 can be fine-tuned to improve the riding comfort.

[0030] For details, see Figure 3 In this embodiment, from top to bottom, there are respectively a seat 2, a turntable upper component 3, a turntable lower component 4 and a long slide rail assembly 5. The seat 2 and the turntable upper component 3 are fixedly arranged, the turntable upper component 3 and the turntable lower component 4 are rotatably arranged, the turntable lower component 4 and the long slide rail assembly 5 are slidably arranged, and the turntable lower component 4 and the long slide rail assembly 5 slide via other driving parts.

[0031] Specifically, a method for operating and controlling a seat that can automatically rotate to provide support comprises the following steps:

[0032] S1: Detect whether the side wing of seat 2 is squeezed and obtain pressure signal;

[0033] S2: Detecting the driving state of the vehicle in which the seat 2 is squeezed;

[0034] S3: When the vehicle driving state satisfies the preset pressure signal, vehicle speed, and steering angle, the seat 2 is rotated in the opposite direction.

[0035] Specifically, by using intelligent sensors to monitor the pressure changes on the side wings of seat 2 in real time, the passenger's body dynamics and posture can be instantly sensed. When the passenger turns, accelerates suddenly or brakes suddenly, the body may tilt due to inertia. At this time, the pressure on the side wings increases, and the sensor can quickly capture this change. In addition, a comprehensive judgment is made based on the vehicle's driving status (such as vehicle speed, steering angle), and specific situations in which passengers need additional support can be accurately identified, 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 passengers losing control of their bodies.

[0036] Specifically, the pressure sensor 1 is installed on both sides of the seat cushion of the seat 2 and / or on both sides of the backrest of the seat 2. The pressure sensor 1 is electrically connected to the control system to obtain the pressure signal of the waist and buttocks of the human body and transmit it to the control system. During the driving of the vehicle, especially in sharp turns, sudden acceleration or sudden braking, the passenger's body may move due to inertia, resulting in an unstable sitting posture. At this time, the pressure sensor 1 can quickly sense the changes in the passenger's body and adjust the supporting force of the seat 2 through the control system to provide the passenger with more stable support, thereby improving driving safety. The combination of the pressure sensor 1 and the control system realizes the intelligent control of the seat 2. Through real-time monitoring and data analysis, the control system can automatically complete the adjustment task of the seat 2 without 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 may be installed on the seat 2 / the vehicle.

[0038] Specifically, the pressure signal of the side wing of the seat 2 is obtained and collected via 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 shape. The control system receives and uses the larger pressure signal value that has reached the threshold, and the control system obtains the vehicle's driving speed. When the pressure signal value collected by the pressure sensor 1 on the side wing of the seat 2 on one side is significantly greater than that on the other side, this usually means that the driver or passenger's body may have tilted / when the vehicle is turning, the pressure sensor 1 transmits the collected pressure signal to the control system, and the control system 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 speed. When the vehicle speed is not less than 30KM / H, the speed information collected by the speed sensor is transmitted to the control system to judge the steering angle of the vehicle. When the side wings of the seat 2 are squeezed, the system can sense the changes in the body posture of the passenger or driver in real time by detecting the pressure signal. Combined with the vehicle speed information, when the vehicle speed reaches or exceeds 30KM / H and the steering angle meets the preset conditions, the seat 2 automatically rotates in the opposite direction to provide more stable support for the passenger or driver, reducing the safety hazards caused by body tilt or imbalance. Under high-speed driving and complex road conditions, the automatic rotation function of the seat 2 can assist the passenger or driver to maintain body balance, reduce the body shaking caused by vehicle bumps or steering, and make the driving process more stable and smooth.

[0040] Specifically, when the steering angle of the vehicle is not 0°, the seat 2 rotates in the opposite direction, and the reverse rotation angle of the seat 2 is 0-8°. Too large a rotation angle may cause the passenger or the driver to feel uncomfortable or lose balance. Limiting the rotation angle within 0-8° can effectively avoid this situation and ensure that the support adjustment of the seat 2 is both effective and comfortable. At the same time, the rotation angle range of 0-8° is relatively universal and can meet the needs of more vehicle models and vehicle interior layouts. The reverse rotation of the seat 2 within the range of 0-8° can enhance the lateral support for the passenger or driver.

[0041] Specifically, when the vehicle speed is between 30-45KM / H and the vehicle is turning, the seat 2 rotates in the opposite direction by 0-3°; when the vehicle speed is between 45-60KM / H and the vehicle is turning, the seat 2 rotates in the opposite direction by 3-6°; when the vehicle speed is greater than 60KM / H and the vehicle is turning, the seat 2 rotates in the opposite direction by 6-8°. The vehicle speed is subdivided into three intervals: 30-45KM / H, 45-60KM / H and greater than 60KM / H, and different seat 2 rotation angle ranges are set for different intervals. This refined adjustment can more accurately adapt to driving needs at different vehicle speeds and provide a more personalized support experience. In each speed range, the reverse rotation angle of the seat 2 has clear upper and lower limits. This precise control can ensure that the support adjustment of the seat 2 is neither excessive nor insufficient, and achieves the best support effect. By increasing the reverse rotation angle of the seat 2, additional lateral support is provided to the passenger or driver, reducing body tilt and maintaining body balance.

[0042] Specifically, within the corresponding range, when the vehicle speed is constant, the greater the steering angle, the greater the reverse rotation angle of the seat 2.

[0043] Specifically, X: threshold value of pressure signal intensity level (the specific value is unknown, but it is assumed to have been determined through experiments), Y: threshold value of steering angle (such as 5° to 15°); vehicle speed interval: interval 1: 30KM / H≤v<45KM / H, interval 2: 45KM / H≤v<60KM / H, interval 3: v≥60KM / H;

[0044] If (pressure signal strength level == X) and (vehicle speed is in interval 1 and steering angle >= Y) then rotation angle = 0-3°;

[0045] If (pressure signal strength level == X) and (vehicle speed is in interval 2 and steering angle >= Y) then rotation angle = 3-6°;

[0046] If (pressure signal strength level == X) and (vehicle speed is in interval 3 and steering angle >= Y) then rotation angle = 6-8°;

[0047] Otherwise, the rotation angle = 0° (ie, keep the current angle and do not rotate).

[0048] Specifically, the pressure signal intensity level X needs to be set according to the user's body shape.

[0049] Specifically, the turned seat 2 automatically resets its angle according to the squeezing signal, vehicle speed and steering angle, and can automatically adjust the angle of the seat 2 according to the body posture and driving status of the passenger or driver, which helps to reduce fatigue caused by long-term driving and improve driving comfort and pleasure. The seat 2 can maintain a smooth transition during the automatic resetting process to avoid sudden movement or shaking that may cause discomfort to the passengers or drivers, which helps to improve the overall driving experience.

[0050] Specifically, the automatic resetting speed of the seat 2 angle is proportional to the resetting speed of the steering angle.
