Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
Example 1
As shown in fig. 1, an intelligent seat back of an automobile comprises an electronic control ECU unit 100 of a vehicle body, a seat controller 200, a feedback signal unit 210, a pressure sensor 220, a back control motor 230, a back frame 240 and a central control display screen 110 of the automobile; the pressure sensor 220 is electrically connected to the seat controller 200 through the feedback signal unit 210, wherein the pressure sensor 220 is used for detecting the pressure exerted on the back of the seat by the back of a person and sending the pressure to the feedback signal unit 210, and the feedback signal unit 210 feeds back a signal to the seat controller 200 after receiving the signal sent by the pressure sensor 220;
the vehicle body electronic control ECU unit 100 is electrically connected to the seat controller 200, and is configured to send a command for starting movement of the seat back to the seat controller 200;
the seat controller 200 is electrically connected to the backrest frame 240 through the backrest control motor 230, and is configured to control movement of the backrest frame 240; the seat controller 200 receives a signal transmitted from the body electronic control ECU unit 100, turns on the backrest motor 230 disposed in the vehicle seat, and the backrest motor 230 rotates in both directions to drive the backrest frame 240 to move forward and backward.
The vehicle body electronic control ECU unit 100 is electrically connected to a vehicle central display screen 110, which is used to display whether the vehicle intelligent seat backrest is started.
The body electronic control ECU unit 100 may be an ECU electronic control unit of an existing vehicle.
The seat controller 200 may be an 8-bit MCU such as the STM8L series of microcontrollers.
The pressure sensor 220 is a normal temperature industrial control pressure sensor, such as PT124G pressure sensor, and when the pressure sensor is used, the signal feedback unit 210 adjusts the signal by using the signal adjusting circuit shown in fig. 2, and the signal adjusting circuit is composed of an instrumentation amplifier and an analog-to-digital converter (ADC). The small output voltage from the sensor is amplified to the level suitable for the ADC by the instrumentation amplifier, and then the amplified sensor output voltage is converted into a digital form by the ADC and then is sent to the controller or the DSP for processing. Or the signal feedback unit can be a pressure transmitter.
In order to facilitate the operation of a driver, the backrest moving switch button 120 is arranged on a steering wheel of the automobile, and the backrest moving switch button (120) is electrically connected with the automobile body electronic control ECU unit 100.
The working process of the utility model is as follows:
the first step is as follows: when the backrest moving switch key is pressed down to start the intelligent seat backrest of the automobile, the seat backrest moving indicator light symbol on the display screen is lightened, at the moment, the electronic control ECU unit 100 of the automobile body transmits an opening signal to the seat controller, the seat controller 200 transmits the opening signal to the feedback signal unit 210, and the feedback signal unit 210 starts to receive a detection signal of the pressure sensor 220.
In the second step, the pressure sensor 220 will detect the force exerted by the person's back on the seat back, and since the driver's body has tilted forward, nearly out of the way of the seat back, the magnitude of the force detected by the pressure sensor is close to zero. After the feedback information unit 210 knows that the pressure is close to zero, the feedback information unit transmits the information to the seat controller 200, and the seat controller 200 controls the backrest control motor to rotate forward, so that the seat backrest tilts forward. The seat back tilts forward continuously until it butts against the back of the driver, at which time the force detected by the pressure sensor 220 increases continuously, and when the force reaches a set value, the pressure sensor 220 feeds back a stop signal to the seat controller 200 through the feedback signal unit 210, and the seat controller 200 controls the back control motor 230 to stop rotating, and the seat back does not move any more.
Thirdly, when the driver wants to lean back, the force applied to the backrest of the seat is continuously increased by the back of the driver, the pressure detected by the pressure sensor 220 is continuously increased compared with the pressure detected by the first step, when the pressure is increased to a set value, the pressure sensor 220 feeds back a backward tilting signal to the seat controller 200 through the feedback signal unit 210, and the seat controller 200 controls the backrest control motor 230 to rotate reversely, so that the seat backrest tilts backward.
Fourthly, when the driver wants to stop continuously tilting the body backward to a certain extent, the force exerted on the seat back by the back of the driver can be reduced, and when the force is reduced to a certain value, the pressure sensor 220 feeds back a backward tilting stop signal to the seat controller 200 through the feedback signal unit 210, and the seat controller 200 controls the back control motor 230 to stop rotating, so that the seat back stops tilting backward.
Example 2
The difference between this embodiment and embodiment 1 is that, in this embodiment, in order to improve driving comfort, a lumbar plate control motor 310 is further included, and the lumbar plate control motor 310 is also controlled by the seat controller 200. So that the degree of the waist plate 320 against the waist of the driver can be increased or decreased, and the driving comfort can be further improved. As shown in fig. 4, the waist board moving switch key is pressed once by plus, the waist board controls the motor to rotate forward for a certain angle, the waist board inclines forward for a certain angle, and then pressed once by plus, the waist board controls the motor to rotate forward for a certain angle, the waist board inclines forward for a certain angle, and thus the waist board inclines forward continuously when the plus is pressed continuously; once the number is subtracted, the waist plate controls the motor to rotate reversely by a certain angle, the waist plate tilts backwards by a certain angle, and once the number is subtracted again, the waist plate controls the motor to rotate reversely by a certain angle, the waist plate tilts backwards by a certain angle, so that the waist plate tilts backwards continuously by subtracting the number continuously; the driver can adjust the waist plate to a comfortable position and stop the key pressing. The waist board control motor adopts a speed reducing motor, the motor rotates for several circles once according to a plus sign set in advance, and then the waist board rotates for several degrees.
The waist board control key and the backrest control key are integrally arranged and are arranged on the steering wheel. And the driver can touch the position by moving the fingers, so that the sight line of the driver can always face forwards in the driving process, and the driver does not need to be distracted or separate one hand to operate the backrest and the waist plate of the automobile seat. And the seat back and the waist board can be automatically adjusted to the position desired by the driver. Generally speaking, the utility model provides a seat back has improved travelling comfort and security that the driver drove the car in-process along with people's back mobile system greatly.
