The wireless network may be based on wireless communication technologies such as bluetooth, wifi, zigBee (ZigBee), internet of things (IOT), infrared, wireless home digital interface (WDHI), and the like.
In one embodiment, the secondary controller 2 or the partial controller 3 is electrically connected to the electrical load device via a wiring harness 4. Inferior controller 2 or divide controller 3 to be connected through pencil 4 with the inside electric load device of seat, can be more stable quick transmit control signal to electric load device, the seat inner space is less, even use pencil 4 to connect, the length of 4 branches of pencil is also shorter, can not increase too much pencil 4 weight.
In one embodiment, the secondary controller 2 or the secondary controller 3 is connected to the electrical load device via a wireless network. In some usage scenarios, connecting the secondary controller 2 and the electrical load device via a wireless network, or connecting the secondary controller and the electrical load device via a wireless network, may save the use of the wiring harness 4.
In one embodiment, as shown in fig. 1, the electrical load device includes one or more of a seat adjustment module 51, an unbelted warning module 52, an audio module 53, a massage module 54, and a human health monitoring module 55.
The seat adjusting module 51 adjusts the seat to a posture position where the driver and the passenger can comfortably sit through a slide rail and an adjusting key arranged in the seat. Generally, the adjusting switches of the automobile seat are positioned on the side surfaces of the seat and can be divided into front and back adjustment, height adjustment, backrest adjustment, waist adjustment, headrest adjustment and the like according to the adjusting direction. The safety of a driver can be effectively protected by a correct driving posture, and if the seat is not suitable in position, the sight line and the control sensitivity of the driver can be influenced, and even traffic accidents can be caused.
The unbelted warning module 52 is a warning prompt that is issued when the driver and the passenger don't fasten the seat belt during the driving of the automobile. When the vehicle detects that the driver and the passenger do not fasten the safety belt, an alarm lamp prompt appears on the instrument board; when the vehicle speed exceeds 20km/h, the vehicle is converted into a voice prompt. The unbelted warning module 52 has sensors provided on the seating surface of the car seat and in the seatbelt-mounted buckle, and sends warning information when it detects that a person is seated on the seat and the sensor is not triggered in the seatbelt-mounted buckle.
The sound module 53 can be arranged in a seat headrest, sends audio signals through a host and a power amplifier on an instrument panel, transmits the audio signals to the branch controller 3 through a wireless network by the main controller 1, and transmits the audio signals to the loudspeaker of the sound module 53 through the wire harness 4 by the branch controller 3, so that surround sound can be formed inside the automobile, people in the automobile can enjoy stable and perfect sound quality, and the dryness in traveling of a driver and passengers is reduced.
The massage module 54 is formed by adding a pneumatic device in the seat, wherein air pressure is provided by an air pump in an engine cabin, and 4 or more air pressure chambers are respectively arranged in the backrest of the seat, so that the lumbar part is protected. Meanwhile, the air pressure cavities are controlled by an electronic oscillator controlled by a computer and arranged in the backrest, and the electronic oscillator changes the pressure in the air pressure cavities according to a programmed program in advance, so that the seat surface of the seat moves along with the air pressure cavities, and the aim of massaging drivers and passengers is fulfilled.
The human health monitoring module 55 is used for testing the physical conditions of the driver and the passenger, such as blood pressure, heart rate, etc., especially the physical conditions of the driver, by the sensor arranged on the car seat, and is very important for the passenger of the car and other vehicles and people on the road. The human health monitoring module 55 can monitor the physical condition of the driver in real time, and when an abnormal condition occurs, the driver and the passenger are reminded to take measures in time. If the automatic driving function of the vehicle is relatively perfect, the vehicle can be automatically driven to a safe position even under the state that the driver loses consciousness.
Many other functions can be arranged in the seat, and most of the functions are realized by driving of electric parts, so that the using amount of the wiring harness 4 in the seat is increased, the wireless network is used for connecting the seat and the main controller 1, the using amount of the wiring harness 4 can be reduced, and the seat is convenient to maintain and replace. The arrangement of the secondary controller 2 or the sub-controller 3 also makes the seat more intelligent and can meet most of the requirements of the car networking.
In one embodiment, as shown in fig. 4, the seat adjusting module 51 includes one or more of a seat front-rear adjusting unit 511, a seat height adjusting unit 512, a seat angle adjusting unit 513, a seat ventilation adjusting unit 514, and a seat temperature adjusting unit 515.
The front and rear seat adjusting unit 511 adjusts the front and rear positions of the seat through a front and rear guide rail and a driving motor arranged below the seat, and can more conveniently and easily tread an accelerator and brake to a driver and the front and rear positions of the seat, so that the fatigue of the driver is relieved.
The seat height adjusting unit 512 adjusts the height of the seat through the upper and lower guide rails arranged below the seat and the driving motor, different heights of drivers can result in different driving visual field ranges, and the heights of the drivers with different heights can be basically consistent through the adjustment of the seat height adjusting unit 512, so that the driving safety is improved.
The seat angle adjusting unit 513 adjusts the angle of the seat back by a hinge structure and a driving motor provided between the seating surface and the back surface of the seat, and can maintain a sitting posture in a standing posture during driving, and can lay the seat flat during leisure, so that a driver and a passenger can relax and have a rest.
The seat ventilation adjusting unit 514 can maintain a constant temperature in the vehicle in summer even if an automatic air conditioner is provided, but since the body of the passenger is in close contact with the seat, air in the contact part is not circulated, which is not beneficial to removing sweat and causes people to feel uncomfortable. The ventilation circulation system of the seat ventilation adjusting unit 514 continuously flows fresh air out of the small holes on the seat cushion and the backrest, prevents the buttocks and the back from accumulating sweat, provides a comfortable riding environment, effectively improves the ventilation environment of the contact part of the human body and the seat surface, and ensures that the contact surface of the human body and the seat is dry and comfortable even if the seat is taken for a long time.
The seat temperature adjusting unit 515 adjusts the sitting temperature of the seat through a heating and cooling device arranged inside the seat, so that a driver and passengers can adjust the temperature of the seat as required besides an automobile air conditioner, for example, when the driver gets on the vehicle in winter in the north, the seat heating function can be started, and the temperature of the seat is not cold any more; in summer in the south, the seat cooling function is started, so that the seat is kept cool and dry.
