In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art of this technology.

[0060] Referring to Figure 1 , an embodiment of the present invention provides a method for adaptively adjusting a vehicle seat neck rest, which specifically includes the following steps:

[0061] S101. Obtain the first pressure distribution information of the seat cushion, the second pressure distribution information of the seat backrest, and the third pressure distribution information of the seat headrest;

[0062] S102. Predict the neck posture data of the target occupant according to the first pressure distribution information, the second pressure distribution information, and the third pressure distribution information;

[0063] S103. Adjust the height of the seat neck rest according to the neck posture data and control the extension of the supporting surface of the seat neck rest so that the supporting surface fits the neck of the target occupant;

[0064] S104. Obtain the neck temperature information of the target occupant and perform ventilation / heating control on the seat neck rest according to the neck temperature information.

[0065] Specifically, the embodiment of the present invention predicts the neck posture of the user based on the pressure distributions of the seat cushion, the seat backrest, and the seat headrest, adaptively adjusts the height and the supporting surface curve of the seat neck rest according to the neck posture, and adaptively adjusts the softness / hardness degree and the ventilation / heating condition of the seat neck rest according to the physiological state of the user, which is applicable to the riding scenarios of users of various body types in different sitting postures, improving the comfort of the vehicle seat and the riding experience of the user.

[0066] Further as an optional implementation manner, the method for adaptively adjusting a vehicle seat neck rest further includes the following steps:

[0067] S201, in response to one of a voice control command, an APP control command, and a button control command, starting a first pressure sensor array disposed on a surface of a seat cushion, a second pressure sensor array disposed on a surface of a seat backrest, and a third pressure sensor array disposed on a surface of a seat headrest, and switching a seat neck support from a dormant state to an active state;

[0068] S202, when the first pressure sensor array, the second pressure sensor array or the third pressure sensor array does not sense a pressure signal within a preset time period, switching the seat neck support from a working state to a dormant state;

[0069] Among them, the first pressure sensor array is used to collect first pressure distribution information, the second pressure sensor array is used to collect second pressure distribution information, and the third pressure sensor array is used to collect third pressure distribution information. The seat neck support is retracted in the upper area of the seat back when in a dormant state.

[0070] Specifically, an embodiment of the present invention provides a seat neck support that can be raised or lowered and adaptively supports the neck. The support is integrated into the upper part of the seat back and has the characteristics of zero-gravity cervical vertebrae support, intelligent height adjustment (0-5cm lifting range, suitable for occupants with a height of 145-200cm) and dual-mode ventilation (active airflow circulation and passive breathable structure). The neck support cooperates with the rotating headrest to provide the passenger's head with an experience of holding the palms together, transfer the pressure of the cervical vertebrae to the seat assembly, and achieve improved comfort; the neck support adopts a bionic mechanical structure design as a whole, including a three-axis linkage adjustment mechanism, a DC motor and a harmonic reducer, and the supporting surface adopts a curved pressure-dividing design, including 8-partition memory gel and a shape memory skeleton, so that the passenger's cervical spine can have zero gravity when in a fixed posture for a long time, so there will be no discomfort such as soreness; it can be opened and closed and actively adjusted by voice / APP / physical knob, and relies on EMG sensors to link with the seat massage system, and the support hardness can be dynamically adjusted according to the massage rhythm; in addition, it also has a collision safety mechanism. After a collision, the neck support can be retracted to a safe position within 30ms to avoid damage to the occupant's body. The neck support is a folding structure with adjustable height as a whole. When folded, the thickness is <50mm and does not occupy the original backrest and rear space.

[0071] Specifically, the user can activate the adaptive adjustment function of the neck rest through any one of voice control instructions, APP control instructions, and button control instructions. After activation, the pressure distribution is collected by the first pressure sensor array arranged on the surface of the seat cushion, the second pressure sensor array arranged on the surface of the seat backrest, and the third pressure sensor array arranged on the surface of the seat headrest. At the same time, the seat neck rest is switched from the sleep state to the working state, and subsequent neck posture prediction and adaptive adjustment of the neck rest can be performed based on the collected pressure distribution information; when the first pressure sensor array, the second pressure sensor array, or the third pressure sensor array does not sense a pressure signal within a preset time period (such as 5S), it means that the user has left the seat or has disengaged from the state of relying on the seat. At this time, the seat neck rest can be switched from the working state to the sleep state.

[0072] Such as Figure 2 As shown in the figure is a schematic diagram of the seat neck rest provided by the embodiment of the present invention when it is in the working state. Among them, 1 represents the seat cushion, 2 represents the seat backrest, 3 represents the seat headrest, and 4 represents the seat neck rest. It can be seen that the seat neck rest of the embodiment of the present invention can perfectly fit the neck curve of the user when working, improving the riding experience of the user.

[0073] Further as an optional implementation manner, the neck posture data of the target occupant is predicted according to the first pressure distribution information, the second pressure distribution information, and the third pressure distribution information, which specifically includes:

[0074] S1021. Determine the body shape information of the target occupant according to the first pressure distribution information;

[0075] S1022. Determine the key back position and posture of the target occupant according to the second pressure distribution information;

[0076] S1023. Determine the key head position and posture of the target occupant according to the third pressure distribution information;

[0077] S1024. Input the body shape information, the key back position and posture, and the key head position and posture into a pre-trained neck posture prediction model to obtain the neck posture data.

[0078] Specifically, the pressure distribution information of the seat cushion is closely related to the occupant's body shape. The pressure distribution of the seat cushion when occupants of different body shapes use the vehicle seat can be collected in advance through experiments. The mapping relationship between the pressure distribution of the seat cushion and the occupant's body shape is fitted through a model, so that the occupant's body shape can be inferred based on the pressure distribution information of the seat cushion in actual applications. The pressure distribution information of the seat back is closely related to the occupant's back posture, and the pressure distribution information of the headrest is closely related to the occupant's head posture. Similarly, the pressure distribution of the seat back / headrest when occupants with different back / head postures use the vehicle seat can be collected in advance through experiments. At the same time, the key point postures of the back / head corresponding to the back / head postures are manually marked, and the mapping relationship between the pressure distribution of the seat back / headrest and the key point postures of the back / head is fitted through a model, so that the key point postures of the occupant's back / head can be inferred based on the pressure distribution information of the seat back / headrest in actual applications.

[0079] After determining the body shape information, the key back point postures, and the key head point postures of the target occupant, input them into a pre-trained neck posture prediction model, and the neck posture data predicted by the model can be obtained.

[0080] Furthermore, as an optional implementation manner, the neck posture prediction model is trained through the following steps:

[0081] S301. Obtain the 3D human body scan data of multiple testers in different sitting postures on the test seat, and determine the corresponding body shape sample information, key back point postures samples, key head point postures samples, and neck posture labels according to the 3D human body scan data;

[0082] S302. Construct training samples according to the body shape sample information, key back point postures samples, and key head point postures samples;

[0083] S303. Input the training samples into a pre-constructed deep learning neural network to obtain neck posture prediction data;

[0084] S304. Determine the loss value according to the neck posture prediction data and the neck posture labels;

[0085] S305. Update the parameters of the deep learning neural network according to the loss value to obtain the neck posture prediction model.

[0086] Specifically, obtain in advance the 3D human body scan data of multiple testers in different sitting postures on the test seat. This 3D human body scan data can accurately depict the postures of various parts of the tester's body, thereby determining the corresponding body type sample information, key back point postures, key head point postures, and neck posture labels. It should be noted that the body type sample information can be represented by different body type parameters, the key back point postures can be represented by the positions and postures of multiple back key points, the key head point postures can be represented by the positions and postures of multiple head key points, and the neck posture labels can be represented by the positions and postures of multiple neck key points, or can also be represented by the relative position of the entire neck, as well as the cervical curvature and cervical bending angle.

[0087] Construct a training sample based on the body type sample information, key back point postures, and key head point postures. Input this training sample into a pre-constructed deep learning neural network to obtain neck posture prediction data. Determine the loss value based on the neck posture prediction data and the neck posture label using a preset loss function (such as cross-entropy loss). Update the parameters of the deep learning neural network according to the loss value, and then re-enter the training sample. After multiple iterations until the preset convergence condition is reached, the neck posture prediction model can be obtained.

[0088] Further, as an optional implementation manner, adjust the height of the seat headrest according to the neck posture data and control the extension of the supporting surface of the seat headrest so that the supporting surface fits the neck of the target occupant. Specifically, it includes:

[0089] S1031. Determine the neck height, cervical curvature, cervical rotation angle, and the distance between the neck and the plane where the seat back is located according to the neck posture data;

[0090] S1032. Determine the corresponding supporting surface curve according to the cervical curvature and cervical rotation angle;

[0091] S1033. Adjust the height of the seat headrest according to the neck height, and adjust the surface posture of the supporting surface according to the supporting surface curve. Furthermore, control the extension of the supporting surface according to the distance, so that the supporting surface fits the neck of the target occupant.

[0092] Specifically, the neck pose data predicted according to the foregoing steps can determine the positions and poses of multiple neck key points of the target occupant, or the relative positions of the neck with respect to the back and head, as well as the cervical curvature and cervical bending angle. Thus, the neck height of the target occupant, the distance between the neck and the plane where the seat backrest is located, and the cervical curvature and cervical rotation angle can be calculated / directly obtained. Corresponding most fitting support surface curves are pre-designed for different cervical curvatures and cervical rotation angles to form a support surface curve database for matching that can be continuously updated according to usage conditions. According to the cervical curvature and cervical rotation angle obtained in real time, the corresponding support surface curve can be matched in this support surface curve database. Adjust the height of the seat headrest according to the neck height, adjust the surface pose of the support surface according to the support surface curve, and control the extension of the support surface according to the distance between the neck and the plane where the seat backrest is located, so that the support surface can fit the neck of the target occupant.

[0093] Further as an optional implementation manner, obtain the neck temperature information of the target occupant, and perform ventilation / heating control on the seat headrest according to the neck temperature information, which specifically includes:

[0094] S1041. Obtain the neck temperature information through a temperature sensor provided on the surface of the support surface;

[0095] S1042. Determine the corresponding ventilation gear / heating temperature according to the neck temperature information;

[0096] S1043. Perform ventilation / heating control on the seat headrest according to the ventilation gear / heating temperature;

[0097] Wherein, the support surface is provided with a plurality of air outlets, the side surface of the seat headrest is provided with a plurality of air inlets, and an air flow circulation device and a temperature control device are arranged inside the seat headrest.

[0098] Specifically, the air flow circulation device inside the seat headrest adopts a laminar air duct design, and a hidden vortex fan (noise <28 dB) is provided on each of the left and right sides; the temperature control device inside the seat headrest adopts a safety isolation design, that is, the heating element is not in direct contact with the support surface, but the heating element is fixed at an internal position of the headrest close to the seat backrest, and the heat is transferred to the support surface through air flow or other flexible media; at the same time, the support surface can adopt a 3D knitted silver ion fiber fabric, which can effectively antibacterial.

[0099] Obtain the neck temperature information through a temperature sensor provided on the surface of the support surface. When the neck temperature is higher than the normal range, start the air flow circulation device. When the neck temperature is lower than the normal range, start the heating device. The specific ventilation gear and heating temperature can be determined in combination with the real-time neck temperature, which is not elaborated in this embodiment of the present invention.

[0100] It should be noted that the ventilation / heating function of the neck support can be independent of the adaptive posture adjustment of the neck support. The user can start them simultaneously through corresponding instructions, or only start the adaptive posture adjustment, or turn off the ventilation / heating function during use.

[0101] As a further optional implementation, the method for adaptively adjusting the vehicle seat neck support further includes the following steps:

[0102] S105. Obtain the neck electromyogram signal of the target occupant through the electromyogram sensor arranged on the supporting surface;

[0103] S106. Determine the neck muscle state of the target occupant according to the neck electromyogram signal, and adjust the softness and hardness of the supporting surface according to the neck muscle state.

[0104] Specifically, after the supporting surface contacts the occupant's neck, the neck electromyogram signal of the occupant can be obtained through the electromyogram sensor made of flexible material arranged on the supporting surface, and the neck muscle state of the occupant can be analyzed. Then, the softness and hardness of the supporting surface can be adjusted according to the neck muscle state, or the seat massage function can be linked to realize the dynamic adjustment of the support hardness with the massage rhythm, further improving the riding experience of the user.

[0105] The above has described the method steps of the embodiments of the present invention. It can be recognized that the embodiments of the present invention predict the neck posture of the user based on the pressure distribution of the seat cushion, seat backrest, and seat headrest, adaptively adjust the height and the curve of the supporting surface of the seat neck support according to the neck posture, and adaptively adjust the softness and hardness as well as the ventilation / heating condition of the seat neck support according to the physiological state of the user. It is applicable to the riding scenarios of users of various body types in different sitting postures, improving the comfort of the vehicle seat and the riding experience of the user.
