Description

Technical Field

Users have higher and higher requirements for seat comfort, especially in the long-term driving and riding process. The posture, hardness and other factors of the seat will directly affect the physical comfort and mood of the driver and passengers. The non-adjustable seats have a large difference in the subjective riding experience of drivers and passengers of different body shapes, such as fat, thin, tall and short, in different driving conditions of long-distance driving, short-distance driving and intense driving, and it is difficult to meet people's growing comfort requirements. Especially when the seat position does not meet the riding experience of the driver and passengers, it is easy to cause physical discomfort, bad mood, fatigue, and even abnormal physical condition of the driver and passengers.

[0003] In the related technology, the visual recognition technology of the in-car camera is used to capture the height, fatness and thinness of the human body according to the camera image, and then the algorithm model is built to achieve adaptive adjustment of the seat without adding additional special sensors, providing the driver with a technological and convenient user experience, ensuring comfort while ensuring safety. However, on the one hand, the investment cost of adding cameras and related algorithm modules is too high. On the other hand, when using cameras for visual recognition, since the camera is easily affected by the environment and the vehicle usage scene, it often leads to inaccurate results, and the seat cannot make accurate adaptive adjustments, affecting the user's riding experience.

[0051] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] In view of the problem in the related art that the seat adaptive adjustment function cannot stably and accurately identify the body characteristics of the driver and passengers, resulting in the seat being unable to accurately perform the adaptive adjustment function.

[0053] In a first aspect, the present application provides an adaptive seat, the adaptive seat comprising: a seat assembly, an air delivery device, a monitoring device and a control component; wherein:

[0054] A seat assembly, wherein an air bag assembly is arranged therein, and the shape of the seat assembly is adjustable; an air supply device, which is connected to the air bag assembly and is used to inflate or evacuate the air bag assembly; a monitoring device, which is used to monitor the pressure change parameters of the air bag assembly and the shape adjustment parameters of the seat assembly; a control component, which is connected to the seat assembly and the monitoring device signals, and the control component is configured as follows: when a user sits on the seat assembly, the control component calculates the user's body shape characteristics based on the pressure change parameters and the shape adjustment parameters, and adjusts the inflation amount of the air bag assembly and the shape of the seat assembly based on the user's body shape characteristics.

[0055] It is worth noting that when a user sits on the seat, pressure will inevitably be applied to the airbag assembly in the seat assembly. In the above embodiment, the monitoring device can monitor the pressure change value of the airbag assembly and calculate the user's physical characteristics based on the pressure change value.

[0056] In some specific implementations, such as Figure 2 As shown, the seat assembly includes: a seat portion 1, a headrest portion 2 and a leg support portion 3; wherein,

[0057] The seat portion 1 comprises an adjustable cushion unit 11 and a backrest unit 12. A headrest portion 2 is mounted on the backrest unit 12, and the angle of the headrest portion 2 is adjustable; and a leg rest portion 3 is mounted on the cushion unit 11, and the length and angle of the leg rest portion 3 are adjustable.

[0058] It can be understood that the above-mentioned parts can be adjusted separately, so that the seat assembly has the functions of front and rear adjustment, backrest angle adjustment, and seat cushion angle adjustment.

[0059] Furthermore, the airbag assembly includes: a backrest airbag unit, a seat cushion airbag unit, a leg support airbag unit and a headrest airbag unit; wherein,

[0060] A backrest airbag unit is installed in the backrest unit 12, and the backrest airbag unit is connected to the monitoring device; a seat cushion airbag unit is installed in the seat cushion unit 11, and the seat cushion airbag unit is connected to the monitoring device; a leg support airbag unit is installed in the leg support part 3, and the leg support airbag unit is connected to the monitoring device; a headrest airbag unit is installed in the headrest part 2, and the headrest airbag unit is connected to the monitoring device.

[0061] It is understandable that corresponding airbag units are arranged in various areas of the seat assembly, and airbags in different positions can reflect the body dimensions of different areas of the human body.

[0062] In some preferred implementations, the control component calculates the user's body shape characteristics according to the pressure change parameter and the shape adjustment parameter, including:

[0063] The seat assembly and the air delivery device are driven to perform a pre-detection action, and the shape adjustment parameters of the seat assembly and the pressure change parameters of the airbag assembly during the pre-detection action are recorded through a monitoring device, and then the user's human body characteristic data is calculated based on the shape adjustment parameters and the pressure change parameters.

[0064] It is understandable that when a user sits on the seat, the seat assembly and the air supply device first perform a corresponding pre-detection action, and then calculate the user's body characteristic data based on the shape adjustment parameters and pressure change parameters obtained from the pre-detection action.

[0065] Specifically, the control component drives the seat assembly and the air delivery device to perform a pre-detection action and the monitoring device records the shape adjustment parameters of the seat assembly and the pressure change parameters of the airbag assembly during the pre-detection action, including:

[0066] Action 1: drive the leg rest portion 3 of the seat assembly to perform an extension action until the pressure of the leg rest airbag unit reaches a preset value, and at the same time monitor the pressure change in the sensing airbag on the leg rest portion 3. When the pressure increases to a first preset threshold, stop the extension adjustment of the leg rest portion 3, and record the extended length of the leg rest portion 3 at this time.

[0067] Action 2: Drive the leg rest portion 3 of the seat assembly to perform a lifting action. During the operation, monitor the pressure change in the sensing air bag under the leg rest. When the pressure reaches a second preset threshold, stop adjusting the angle of the leg rest portion 3 and record the adjustment angle of the leg rest at this time.

[0068] Action three: drive the headrest part 2 to move upward from the lowest position to the maximum value, and record the air pressure change of the headrest airbag unit in the headrest part 2 during the operation, and record the height adjustment stroke of the headrest part 2 when the air pressure in the headrest airbag unit is maximum.

[0069] In some optional embodiments, the control component drives the seat assembly and the air delivery device to perform a pre-detection action, including: driving the inflation device to inflate the airbag components 4 located on the side wings of the backrest airbag unit and the seat cushion airbag unit.

[0070] Furthermore, when the side airbags of the backrest airbag unit come into contact with the human body during inflation, the pressure increases significantly, and inflation is stopped at this time, and the inflation time at this time is recorded. When the side airbags of the seat cushion airbag unit come into contact with the human body during inflation, the pressure increases significantly, and inflation is stopped at this time, and the inflation time at this time is recorded.

[0071] It is worth mentioning that the inflation time recorded by the side airbags of the backrest airbag unit and the seat cushion airbag unit can be used to calculate and judge the user's fat or thin indication, and adjust the inflation time of the side airbags in the subsequent adaptive adjustment process according to the fat or thin indication.

[0072] In some optional implementations, the pressure change of the air bag in the middle of the seat cushion air bag unit can be used to calculate the user's weight parameter.

[0073] In some preferred embodiments, the control component calculates the user's human body characteristic data based on the morphological adjustment parameters and the pressure change parameters, including: calculating the length of the upper body of the human body based on the adjustment stroke of the headrest portion 2; calculating the length of the human thigh based on the extended length of the leg rest portion 3; and calculating the length of the human calf based on the extended length and adjustment angle of the leg rest portion 3.

[0074] In some optional implementations, such as Figure 2 As shown, the backrest airbag unit includes: a plurality of airbag components 4, the plurality of airbag components 4 are arranged in the middle and side wings of the backrest unit 12, and each of the airbag components 4 is connected to the monitoring device.

[0075] In some specific embodiments, the backrest airbag unit includes: 10 airbags 4 located in the middle and 2 airbags 4 arranged on the side wings. The seat cushion airbag unit includes: 6 airbags 4 located in the middle area and 2 airbags 4 arranged on the side wings. The leg support airbag unit includes 2 airbags 4 and 1 induction airbag.

[0076] Specifically, Figure 3 As shown, the airbag member 4 includes: three first airbags 41 and second airbags 42; wherein,

[0077] Three first air bags 41 are stacked and interconnected, and the first air bags 41 are connected to the air delivery device through an air pipe; a second air bag 42 is pre-filled with air, and the second air bag 42 is arranged below the three first air bags 41, and the first air bag 41 is connected to the air delivery device through an air pipe.

[0078] It can be understood that in the above embodiment, the airbag member 4 has a massage function, and the air pressure in the first airbag 41 can be changed by supplying air to massage the user leaning on the airbag member 4 .

[0079] It should be noted that the backrest airbag unit, seat cushion airbag unit, leg support airbag unit and headrest airbag unit are all pre-filled with air, and after the seat is assembled, the air pressure values ​​in the airbags have been recorded in the seat controller.

[0080] Preferably, the air delivery device comprises: a backrest solenoid valve and a seat cushion solenoid valve; wherein,

[0081] A backrest solenoid valve is installed in the backrest unit 12, and the backrest solenoid valve is connected to the backrest airbag unit and the headrest airbag unit; a seat cushion solenoid valve is installed in the seat cushion unit 11, and the seat cushion solenoid valve is connected to the seat cushion airbag unit and the leg support airbag unit.

[0082] Further, an audio player is provided in the headrest portion 2, and the audio player is connected to the control component signal. It is configured so that when the user sits on the seat assembly, the audio player plays a voice prompt that the passenger seat adaptive adjustment is started.

[0083] In a second aspect, the present application provides a seat adaptive adjustment method using the above-mentioned adaptive seat, which comprises the following steps:

[0084] Step S1, detecting the pressure change of the airbag assembly to determine whether the user is sitting on the seat assembly.

[0085] Specifically, when the user sits on the seat assembly, the seat cushion airbag unit is subjected to pressure and transmits a signal to the seat controller; the seat controller drives the audio system in the headrest portion 2 to play a voice message "seat adaptive adjustment is starting" to inform the user that the seat adaptive adjustment will be started.

[0086] Step S2: driving the seat assembly and the air delivery device to perform a pre-detection action, and recording the shape adjustment parameters of the seat assembly and the pressure change parameters of the airbag assembly during the pre-detection action through a monitoring device.

[0087] Specifically, the above-mentioned driving the seat assembly and the air delivery device to perform the pre-detection action includes: driving each adjustable part of the seat assembly to perform the adjustment action from the initial position until the air pressure value of the airbag assembly in the seat assembly reaches the corresponding preset value

[0088] It is worth noting that if Figure 4 , Figure 5 and Figure 6 As shown, before performing the pre-test action, it is necessary to determine the H point of the adaptive seat by testing the seat with a dummy according to industry standards. Optionally, the H point of a passenger car is a reference point that can more accurately determine the position of the driver or passenger in the seat, and is the "span point" of the rotation point connecting the torso and the thigh. After the seat is assembled, it is necessary to perform an electrical inspection on the seat; in the unloaded state, the control component will read the air pressure value in all the inductive air bags and record it in the seat controller as a preset value.

[0089] Furthermore, a fake buttock is used to apply force to the seat cushion, with the contact between the fake buttock and the cushion as the starting point. Every time 1 mm of pressure is pressed down, the pressure value in the 6 seat cushion massage air bags is recorded and stored in the seat controller; when the user sits on the seat assembly 1, the seat cushion air bag component 4 is subjected to pressure, and the seat cushion pneumatic system controller receives the pressure change and transmits the signal to the control component.

[0090] The above step S2 comprises:

[0091] Step S2a, the control component of the seat collects the pressure value of the seat cushion airbag unit, and compares it with the recorded pressure value of the seat cushion airbag unit to determine the depression amount H1 of the seat cushion airbag unit by the user at this time.

[0092] Step S2b, the seat controller drives the headrest to move upward from the designed position to the highest position, and records the air pressure changes of the headrest sensing airbag and the headrest travel at the corresponding time during operation; after the adjustment is completed, the software reads the moment of maximum air pressure and the height adjustment travel L2 of the seat headrest.

[0093] Step S2c: According to the previous preset calibration, when the headrest portion 2 is at the lowest position, the distance from point H to the headrest airbag unit is L1.

[0094] Step S2d: According to the previous preset calibration (i.e., the measurement in the preset test with a dummy sitting on the seat), the depression amount H2 of the seat cushion unit 11 is determined to determine the user's torso angle α when reaching the designed position.

[0095] Step S2e, driving the leg support portion 3 of the seat assembly to extend and lift until the pressure of the leg support airbag unit reaches a preset value.

[0096] Specifically, the control component drives the leg support part 3 to extend, and at the same time monitors the pressure change in the leg support airbag unit on the leg support part 3. When the pressure increases to a first preset threshold, the leg support part 3 is stopped from extending and adjusting, and the length L3 of the leg support extended at this time is recorded. Figure 5 As shown, when the preset leg support part 3 reaches the final position, the distance from point H to the front end of the leg support is L4, and the distance from the back of the thigh to the center of the knee is L5.

[0097] Furthermore, the control component drives the leg rest 3 to lift upward; during operation, the pressure change in the sensing air bag under the leg rest 3 is monitored, and when the pressure reaches the second preset threshold, the angle adjustment of the leg rest 3 is stopped, and the adjustment angle of the leg rest 3 at this time is recorded as δ .like Figure 6 As shown, according to the previous calibration results, the adjustment angle of the leg support part 3 is δ When , the calibration result corresponds to the inclination angle of the thigh as θ, the angle between the back of the thigh and the thigh line as ε, the height from point H to the heel point as H3, and the height from the ankle to the heel point as H4.

[0098] Step S2f, driving the headrest portion 2 to move upward from the lowest position to the maximum position.

[0099] Specifically, the control component drives the headrest 2 to move upward from the lowest position, records the air pressure change of the headrest airbag unit in the headrest 2 during operation, and records the height adjustment stroke L of the headrest at the time when the air pressure in the headrest airbag unit is the maximum. 12 .

[0100] Step S2g, inflate the backrest airbag unit, and when the side airbags of the backrest airbag unit come into contact with the human body during inflation and the pressure obviously increases to a preset value, the inflation is stopped, and the inflation time at this time is recorded.

[0101] Step S2h, the seat control component drives the seat cushion solenoid valve, which further drives the seat cushion side wing airbags to inflate. When the side wing airbags come into contact with the human body during inflation and the pressure significantly increases to a preset value, inflation is stopped and the inflation time at this time is recorded.

[0102] It should be noted that some of the above steps are performed before the user performs a pre-detection action, and the calibration relationship of relevant parameters (such as the amount of pressure, the size of each angle of the human body, etc.) and the preset parameters are all obtained by Figure 4 , Figure 5 and Figure 6 The adaptive seat is pre-calibrated and designed using a dummy.

[0103] Step S3: Calculate the user's body feature data according to the morphology adjustment parameter and the pressure change parameter.

[0104] Step S3a, calculate the user's upper body length L according to the following formula 21 :

[0105] L 21 =L1+L2*cosα+(H1-H2) / cosα;

[0106] Among them, L2 is the adjustment stroke of the seat headrest in the pre-detection action, L1 is the distance from point H to the headrest airbag unit in the preset calibration stage, H2 is the depression amount of the seat cushion unit 11 in the preset calibration stage, and H1 is the depression amount of the seat cushion airbag unit by the user in the pre-detection action.

[0107] Step S3b: Calculate the user's thigh length L according to the following formula: 22 :

[0108] L 22 =L3+L4+L5;

[0109] Among them, L3 is the extended length of the leg support part 3 in the pre-detection action, and L4 and L5 are respectively the distance from point H to the front end of the leg support and the distance from the back of the thigh to the center of the knee after the leg support part 3 reaches the final position in the pre-detection action.

[0110] In some optional implementations, the values ​​in L4 and L5 are obtained by calibrating the extended length of the leg support portion 3 in the previous preset calibration stage. That is, after measuring the corresponding L3, L4 and L5 can be obtained according to the calibration results.

[0111] Step S3c: Calculate the user's calf length L according to the formula 23 :

[0112] L 23 =(L 22 *sinθ+H3-H2+H1-H4) / cos(δ-θ);

[0113] in, δ In order to pre-detect the adjustment angle of the leg support part 3 when it reaches the stop position during the action, according to the calibration correspondence: the preset inclination angle of the thigh is θ, the preset angle between the back of the thigh and the thigh line is ε, the preset height from point H to the heel point is H3, and the preset height from the ankle to the heel point is H4.

[0114] Step S3d, calculating the user's height L according to the formula:

[0115] L=L 21 +L 22 +L 23 ;

[0116] Among them, each parameter is calculated or measured in the above steps.

[0117] It is worth noting that the user's height is calculated based on the measured value of the pre-detection action and the calibration result of the preset calibration stage, which has higher accuracy and does not rely on camera equipment, so the cost investment is low.

[0118] In some optional embodiments, the user's fatness or thinness can be calculated based on the inflation time of the side wing airbags of the backrest airbag unit and the side wing airbags of the seat cushion airbag unit;

[0119] Furthermore, the user's weight is calculated from the airbag pressures in the middle area of ​​the backrest airbag unit and the airbag pressures in the middle area of ​​the seat cushion airbag unit.

[0120] It is worth mentioning that

[0121] Step S4: adjusting the shape of the seat assembly and the inflation amount of the airbag assembly according to the human body characteristic data.

[0122] It is worth mentioning that the recommended usage position is given to the user based on a comprehensive calculation of height, fatness, and weight information; the seat slide rails are adjusted to give the user enough foot space, the seat cushion adjustment and leg rest are adjusted to give the user appropriate leg support, the backrest angle is adjusted to give the user appropriate backrest angle support, the headrest is adjusted to give the user appropriate head support, and the side support airbags are adjusted to give the user appropriate side support.

[0123] Furthermore, after the adjustment is completed, the seat control component drives the headrest part 2 speaker to play the voice "seat adaptive adjustment has been completed" to inform the user that the seat adaptive adjustment has been completed.

[0124] In summary, the present application sets an air cushion in the seat and uses the pressure change of the air cushion to accurately calculate the body shape of the current user, thereby recommending a suitable sitting posture to the user. This reduces the cost of the adaptive seat and improves the accuracy of the adaptive adjustment, thus meeting the user's riding comfort requirements.
