The "connection" and "coupling" involved in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0028] The programs involved or relied upon in the following embodiments are all conventional programs or simple programs in the technical field, and those skilled in the art can make conventional selections or adaptive adjustments according to specific application scenarios.

[0029] Unless otherwise specified, the components and devices involved in the following embodiments are conventional commercially available products.

[0030] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] This example discloses a car seat, see Figure 1 , which includes a seat cushion 1 and a backrest 2. In order to ensure that the seat is adapted to the sitting posture of the driver and passenger and ensure the comfort of the sitting posture, in this embodiment, the backrest 2 is set with an adjustable opening and closing angle relative to the seat cushion 1, so that the driver and passenger can adjust the angle between the backrest 2 and the seat cushion 1 according to their riding experience. In order to achieve the on-demand adjustment of the backrest 2, in this example, a seat bottom shell is relatively fixed on both sides of the seat cushion 1, and the bottom two sides of the backrest 2 are respectively hinged to the seat bottom shell 11. The seat bottom shell 11 is provided with a drive motor for driving the backrest 2 to rotate relative to the hinge axis, thereby realizing stepless adjustment of the backrest angle.

[0032] See also Figure 1, the top of the backrest 2 is provided with a shoulder pillow 3, a neck pillow 4 and a headrest 5, wherein the shoulder pillow 3, the neck pillow 4 and the headrest 5 are used to support the shoulders, neck and head of the driver and passenger, respectively, to ensure the support force on the corresponding parts of the body and reduce the muscle tension during long-term driving. However, considering that different drivers and passengers have different body structures such as body length, in order to achieve that the shoulder pillow 3, the neck pillow 4 and the headrest 5 can effectively support the corresponding parts of the driver and passenger's body, in this embodiment, the shoulder pillow 3, the neck pillow 4 and the headrest 5 are coaxially arranged with the backrest 2, and the shoulder pillow 3, the neck pillow 4 and the headrest 5 can be moved and adjusted along the axial direction relative to the backrest 2, so as to be adaptively adjusted according to the physical characteristics of the driver and passenger. Specifically, in the present embodiment, in order to realize the axial adjustment movement of the shoulder pillow 3, the neck pillow 4 and the headrest 5, a rack is fixedly provided on the backrest 2 along the axial direction of the movement of the shoulder pillow 3, the neck pillow 4 and the headrest 5, and a gear moving along the rack and a motor driving the gear are respectively provided inside the shoulder pillow 3, the neck pillow 4 and the headrest 5, so that the axial movement adjustment of the shoulder pillow 3, the neck pillow 4 and the headrest 5 relative to the backrest is realized by the movement of the gear along the rack. In some other embodiments, a screw is fixedly provided on the backrest 2 along the axial direction of the movement of the shoulder pillow 3, the neck pillow 4 and the headrest 5, and a screw sleeve threadedly connected to the outside of the screw sleeve is provided inside the shoulder pillow 3, the neck pillow 4 and the headrest 5, and a gear is fixedly provided outside the screw sleeve, and the motor with a gear on the power shaft drives the screw sleeve to move along the screw, thereby driving the axial adjustment of the shoulder pillow 3, the neck pillow 4 and the headrest 5.

[0033] In addition, in this embodiment, in order to further improve the support of the shoulder pillow 3 and the neck pillow 4 on the shoulders and neck of the driver, Figure 1 In this example, convex contacts are symmetrically arranged on both sides of the shoulder pillow 3 and the neck pillow 4. The shoulder pillow convex contacts 31 are used to support the shoulders of the driver and the neck of the driver is supported by the neck pillow convex contacts 41, thereby reducing the muscle force of the driver and reducing driving fatigue. In addition, in some other embodiments, considering the differences in body structures of different drivers and passengers, in order to ensure that the shoulder pillow convex contacts 31 and the neck pillow convex contacts 41 can play a good supporting and fixing role on the corresponding parts, in this example, a driving rib for adjusting the position of the convex contact end is arranged in the convex contact, so as to adjust the opening and closing size between the two symmetrical convex contacts according to the needs of the driver and passenger, so as to adapt to different body shapes of the driver and passenger. In this example, the driving rib is an arc-shaped inner rib, one end of which is abutted against the convex contact, and the other end is provided with an arc-shaped groove, and the inner edge of the arc-shaped groove is provided with convex teeth. Therefore, an adjusting motor with a gear at the output end is placed in the arc-shaped groove, and the arc-shaped groove is driven to move relative to the adjusting motor through the cooperation of the gear and the convex teeth on the inner edge of the arc-shaped groove, thereby driving the arc-shaped inner rib to open and close and rotate, thereby achieving the purpose of adjusting the distance between the two convex contact ends.

[0034] Considering that as the driving time increases, the heat of the driver's buttocks will accumulate at the seat cushion 1, which will affect the driver's riding experience, especially when the ambient temperature is high; in addition, when the ambient temperature is low, the air conditioner in the car cannot increase the temperature of the seat in time, which will also affect the driving experience of the driver. To this end, in this embodiment, a ventilation and heating module is embedded in the seat cushion 1, and the ventilation and heating module includes a temperature sensor to monitor the temperature of the seat cushion 1; in addition, the car seat also includes a seat controller that is connected to the car system, and the temperature sensor of the ventilation and heating module is connected to the seat controller, so that the seat controller can obtain the temperature of the seat in real time, and then according to the preset or corresponding instructions of the driver, the ventilation and heating module is started to work to perform corresponding heat dissipation or heating actions. In some other embodiments, the ventilation and heating module uses a temperature and humidity sensor. While monitoring the temperature, it also monitors the sweat dissipation of the driver through humidity, and correspondingly starts the ventilation and heating module for heat dissipation and ventilation.

[0035] Specifically, in this example, in order to realize the heat dissipation or heating function of the ventilation and heating module, see Figure 2 The ventilation and heating module includes a mesh shell 6 that matches the contour of the seat cushion 1 and is embedded in the seat cushion 1. In this example, the mesh shell 6 is in a flat block shape, and the mesh shell 6 has a cavity structure. In the hollow cavity of the mesh shell 6, a number of springs 7 are fixedly arranged in an array between the upper and lower mesh surfaces of the mesh shell. In this example, the mesh shell is formed by weaving steel parts with excellent ductility, and with the elastic effect of the spring 7, the elasticity of the seat cushion is improved while maintaining the hollow cavity structure in the mesh shell, thereby improving the riding comfort; in addition, in this embodiment, the seat cushion 1 is made of breathable material, and the mesh shell 6 is arranged directly below the breathable surface of the seat cushion, and soft breathable material is filled between the two, which is filled with sponge in this example, so that there is an air flow path between the breathable material at the top surface of the seat cushion 1 and the gas in the cavity of the mesh shell 6, and then the ventilation, heat dissipation and heating functions are realized by flowing or heating the gas in the cavity. Correspondingly, a ventilation duct connected to the cavity of the mesh shell 6 is provided in the seat cushion 1, and the other end of the duct is connected to the air vent on the end side of the seat cushion. A ventilation motor is provided in the ventilation duct to draw air and accelerate the air flow and ventilation in the duct; and a heater is also provided in the ventilation duct to heat the airflow entering the cavity of the mesh shell 6, thereby increasing the temperature of the seat cushion and realizing the seat cushion heating function.

[0036] In addition, in this embodiment, the seat cushion 1, the backrest 2, the shoulder pillow 3, the neck pillow 4, and the headrest 5 are respectively provided with massage airbags, each of which is connected to an airbag motor via an air pipe, and each airbag motor is respectively connected to the seat controller in communication, so that the airbag motor can orderly inflate and deflate the massage airbag according to the timing of the corresponding output of the seat controller, and massage in different parts and different modes can be achieved. In some other embodiments, in order to achieve electrical isolation between the seat controller and each airbag motor, a relay is provided between the output end of the seat controller and the airbag motor, and the seat controller indirectly controls the action of the corresponding airbag motor through the relay.

[0037] To massage the legs of the driver and passenger, see Figure 1 , leg pillows 12 are respectively provided on both sides of the seat cushion 1, and the leg pillows 12 are arranged to be raised and lowered relative to the seat cushion 1 along the normal direction of the seat cushion 1, so as to avoid limiting the leg space of the driver and passenger during normal driving and riding, and in the massage mode, the leg pillow rises along the normal direction of the seat cushion 1, and a massage airbag is provided in the leg pillow 12, thereby achieving massage and relaxation of the driver and passenger's leg muscles. In order to achieve the lifting and lowering of the leg pillow 12, a lifting rod is fixed in the leg pillow 12, and the other end of the lifting rod is relatively fixed to the bottom shell of the seat cushion 1, thereby achieving the lifting and lowering of the leg pillow 12 by the extension and retraction of the lifting rod. In some other embodiments, considering the driving comfort, the width between the leg pillows 12 on both sides is larger than the natural width of the legs of the driver and passenger. When the airbags in the leg pillows 12 on both sides are inflated and deflated for massage, the massage intensity and massage contact degree are affected by the position of the legs of the driver and passenger. For this reason, in this example, a side pillow 13 that is retractable along the normal direction of the seat cushion 1 is embedded in the middle of the front end of the seat cushion 1. In the massage mode, the side pillow 13 rises relative to the seat cushion 1 and is located between the legs of the driver and passenger, thereby cooperating with the leg pillows 12 on both sides to limit the position of the legs of the driver and passenger, thereby ensuring that the massage airbags at the leg pillows 12 can effectively contact the leg muscles of the driver and passenger. In some other embodiments, in order to achieve massage and relaxation of the inner leg muscles of the driver and passenger, massage airbags are respectively provided on both sides of the side pillows 13, thereby achieving contact and massage of the inner leg muscles.

[0038] In addition, see Figure 1 , armrests 8 are provided on both sides of the backrest 2 to massage and relax the arms of the driver and passenger. Considering that the armrests 8 may affect the driver and passenger getting on and off the vehicle and operating the center console, in this example, the armrests 8 are hinged to the two sides of the backrest 2, see Figure 3 Only when the massage mode is triggered, the armrest 8 is dropped to facilitate the arm massage action.

[0039] For more information, see Figure 4The armrest 8 includes an armrest shell 81 with a U-shaped cross section, and a rib pillow 82 is provided at the bottom of the armrest shell 81. Therefore, when the armrest 8 is not dropped, the two rib pillows 82 at the bottom of the armrest can support the ribs on both sides of the driver and passenger, reduce the muscle tension of the driver and passenger during the riding process, and improve the riding comfort. In addition, an arm massage airbag is arranged on the inner edge of the U-shaped groove of the armrest shell 81 to massage and relax the arms placed in the armrest groove. In addition, in this embodiment, a massage airbag is also provided at the rib pillow 82. The driver and passenger can choose whether to drop the armrest according to their fatigue level and massage needs, so that the arm massage is performed when it is dropped, and the double rib massage is performed when it is not dropped. In this example, the armrest 8 is hinged to both sides of the backrest through a motor-driven hinge shaft, and the armrest hinge motor is electrically connected to the seat controller, so that the seat controller controls the armrest to drop, and then controls the action of the arm massage airbag or the massage airbag at the rib pillow in the massage mode according to the control output in the seat controller, that is, whether the armrest is dropped. In some other embodiments, in order to detect the position of the armrest when the armrest 8 is manually lowered or raised, a Hall sensor that is communicated with the seat controller is provided at the hinge shaft of the armrest. The position of the armrest is monitored by the Hall sensor, and the movement of the arm massage airbag or the massage airbag at the rib pillow is controlled accordingly according to the position of the armrest.

[0040] In addition, in this embodiment, see Figure 4 , a blood pressure measurement module 83 is provided at the armrest 8 on one side to achieve the purpose of measuring the blood pressure of the driver and passenger. Specifically, the blood pressure measurement module includes an armband fixed at the armrest shell 81, the armband is used to fix the arm of the driver and passenger during the measurement process, and a blood pressure sensor is provided in the armband. By sensing the pressure of the blood vessel wall, the blood pressure information of the subject is output to the seat controller accordingly, and then the blood pressure information is transmitted to the vehicle system through the communication interface of the seat controller for display and storage. Among them, it is necessary to compress the arm blood vessels in the blood pressure measurement. In this embodiment, the compression effect is achieved by fully inflating the massage airbag in the armrest groove; in some other embodiments, in order to avoid the adverse effect of the subject's arm posture on the measurement result, an inflatable airbag is provided in the armband, and the blood pressure compression is achieved by inflating during the blood pressure measurement. In some other embodiments, a pulse sensor is also provided in the armband to detect the heart rate of the driver and passenger while measuring the blood pressure, and the heart rate information is correspondingly transmitted to the vehicle system through the seat controller for display and storage.

[0041] See also Figure 1In this example, a blood oxygen saturation infrared probe 42 is provided at the middle position of the neck pillow 4, which is used to fit the neck of the driver in the driving position, measure the driver's blood oxygen saturation, and transmit the blood oxygen saturation information to the vehicle system through the seat controller, and remind the driver of the risk of fatigue driving according to the preset critical value. In addition, in this embodiment, pressure sensors are also arranged correspondingly at the seat cushion and the backrest and / or the headrest, so that the pressure sensor at the seat cushion can be used to determine whether there are passengers sitting, and the identity information of the passengers can be assisted in determining according to the pressure information, so as to provide a suitable massage experience later; the pressure sensor at the backrest or the headrest can be used to adjust the opening and closing degree of the backrest pressure relative to the seat cushion, thereby improving the convenience of adjustment.

[0042] Based on the above-mentioned automobile seat, this example also discloses a method for controlling an automobile seat, which comprises the following steps: (1) After the seat is powered on, the seat controller determines whether there is a driver or passenger seated based on the pressure sensor value at the seat cushion, and forwards the pressure data to the vehicle's onboard system through the seat controller. At this time, when there is an output signal from the pressure sensor at the seat cushion, that is, when the driver or passenger is seated, and the identity matching function is turned on, the onboard system calls the voice dialogue module to interact with the driver or passenger.

[0043] Specifically, when used for the first time, after the vehicle system reads the numerical information of the pressure sensor at the seat cushion, it will store the numerical value of the pressure sensor in the vehicle system, record the seat position (driver or co-driver, etc.) information, and establish an identity information database for the driver and passengers; when there is identity information in the identity information database of the vehicle system, the vehicle system will match and search according to the numerical value of the seat cushion pressure sensor, find the identity information that matches the pressure numerical value, and call the voice dialogue module and display screen to request the driver and passengers to confirm the identity information according to the search results. When there is no corresponding identity information in the vehicle system, the voice dialogue module collects the driver and passengers' information including nickname, age, health status, voiceprint, etc. and stores it in the identity information database. The next time the seat cushion pressure sensor outputs a signal, the vehicle system can retrieve the identity information according to the weight information corresponding to the pressure sensor and the voiceprint information obtained during voice interaction, so as to quickly determine the identity information of the driver and passengers.

[0044] (2) After determining the identity information of the seated occupants in turn, the vehicle computer system obtains massage instructions that match the health status and personal needs of the occupants in the information database, and transmits the massage instructions to the seat controller for cache, so that when the occupants have massage needs, the seat controller can control each massage airbag to move quickly. In addition, after the seat identity matching function of the vehicle computer system is turned off, the vehicle computer system outputs the default massage instructions to the seat controller.

[0045] (3) When the pressure sensor at the seat cushion outputs a signal, that is, when the driver or passenger is seated, the seat controller obtains the temperature sensor value of the ventilation and heating module in real time, and then starts and stops the ventilation motor and / or heater of the ventilation and heating module in a timely manner according to the preset and corresponding control instructions to perform seat ventilation and heat dissipation or seat heating.

[0046] (4) When the driver or passenger has a seat adjustment demand, the vehicle computer voice dialogue module or the adjustment control button action is awakened by voice or adjustment action, thereby sending a control command to the seat controller. In this embodiment, the seat adjustment command includes backrest angle adjustment, shoulder pillow height adjustment, neck pillow height adjustment, headrest height adjustment, shoulder pillow covering adjustment, and neck pillow covering adjustment. Specifically, when the seat controller receives the backrest adjustment command, it drives the drive motor connected to the backrest hinge shaft to achieve adaptive adjustment of the backrest angle; when adjusting the height of the shoulder pillow, neck pillow and headrest, the seat controller drives the motor inside the shoulder pillow, neck pillow and headrest to adjust the shoulder pillow, neck pillow and headrest along their axis; when receiving the shoulder pillow covering adjustment and neck pillow covering adjustment, the seat controller drives the adjustment motor of the rib inside the convex contact to adjust the width between the two convex contacts, so that the shoulder pillow and neck pillow can effectively support the shoulders and necks of the driver and passenger.

[0047] (5) When the vehicle is parked, the seat controller responds to the blood pressure measurement control command of the main driver's seat and controls the blood pressure measurement module to measure blood pressure and heart rate. In this embodiment, after the driver and passenger have fastened the armband in place, the driver and passenger issue a blood pressure measurement command through the voice dialogue module of the vehicle computer or the touch screen action of the display screen. The blood pressure sensor and pulse sensor obtain the blood pressure information and heart rate information respectively, and forward them to the vehicle computer system through the seat controller for display or voice broadcast, and record them in the corresponding identity information library for storage. In this example, the vehicle computer system queries the corresponding health advice from the cloud database based on the measurement information, and reminds through the display screen or voice broadcast. In addition, in this example, the remaining seats except the main driver can perform blood pressure and heart rate measurement actions while the vehicle is in motion.

[0048] (6) When the vehicle is in motion, the infrared sensor of blood oxygen saturation at the neck pillow monitors the driver's blood oxygen saturation information in real time and transmits it to the seat controller. The seat controller outputs alarm information to the vehicle system according to the preset critical value. The vehicle system reminds the driver through voice or display screen, and reminds the driver to pay attention to fatigue driving in combination with factors such as driving time and number of brake oil releases. In addition, when the vehicle is in motion, the driver and passengers can interact with the vehicle through the vehicle voice dialogue module according to their fatigue level and issue massage instructions. The seat controller responds to the driver's control instructions and activates the massage airbag action at the corresponding position. In this embodiment, the driver and passengers can activate the massage airbag at the corresponding position according to their needs, or select the massage mode recommended by the system according to the health status of the driver and passengers, or the massage mode preset by the system. In order to ensure the safety of the vehicle, in some other embodiments, the massage control channel of the main driver's seat is closed when the vehicle is in motion to prevent the massage action from affecting the driver's safe driving.

[0049] In addition, in this embodiment, the system presets multiple massage modes including nap mode. In the nap mode, the vehicle system adjusts the temperature, light brightness and audio volume in the vehicle accordingly, and the seat controller controls the movement of each massage airbag from heavy to light and stops at a fixed time.

[0050] (7) After the vehicle system obtains the massage control command from the driver and passenger, in order to achieve further convenient adjustment of the backrest, in this example, the pressure sensor at the backrest or headrest collects the pressure information of the driver and passenger, and the driver and passenger controls the adjustment of the seat backrest by reclining. Specifically, the seat controller adjusts the opening and closing degree of the backrest relative to the seat cushion according to the pressure sensed at the backrest or headrest, and stops the backrest adjustment action when the output value of the pressure sensor jumps, so that the driver and passenger can freely adjust the opening and closing degree of the backrest according to their comfort level. In addition, when executing the massage command, the armrests on both sides determine whether to be lowered according to the massage needs of the driver and passenger. After obtaining the armrest position information, the seat controller determines the conduction action of the arm massage airbag or the rib pillow airbag, and controls the lifting action of the leg pillow and side pillow according to the control command, and starts the massage airbag at the corresponding position to perform the massage action.
