Description

Technical Field

[0001] The invention belongs to the field of automobile seats, and in particular relates to an intelligent automobile seat wing adjustment device. Background Art

[0002] At present, most of the side wings of car seats on the market are fixed on the car seats, without adjustability, and cannot meet people's pursuit of high-quality life. At the same time, with the development of science and technology, some car seats have adjustable side wings, but such adjustable car seat side wings are usually adjusted manually and lack intelligence. Passengers usually give up adjusting the side wings of the car seats due to the cumbersome manual adjustment, which makes the adjustable car seat side wings unable to play its original role of improving passenger riding comfort, resulting in a waste of resources.

[0003] CN 108045271 A discloses an adjustable wing structure and a seat having the wing structure, including a main body mechanism, a support frame, a support plate, a mounting plate and a motor. Although the seat can make the wing movable and adapt to diversified user body shapes and needs, it has the following problems: firstly, although the car seat wing adjustment mechanism is controlled by a motor, the manual button operation is not smart enough; secondly, the position of the car seat wing opening needs to be adjusted by pressing buttons continuously, and it is not easy to adjust to an extremely comfortable position at one time; finally, the car seat cushion wing cannot be adjusted together, and the sense of covering is not strong when sitting. Summary of the invention

[0004] In order to solve the problems in the background technology, the present invention provides an intelligent automobile seat wing adjustment device.

[0005] The technical solution of the present invention is as follows:

[0006] An automobile seat structure with intelligently adjustable side wings, comprising a seat pot, a seat back, seat pot side wings arranged on both sides of the seat pot, and backrest side wings arranged on both sides of the seat back, wherein the seat pot is provided with a seat occupancy sensor for detecting whether the buttocks of an occupant are in contact with the seat pot and a sitting sensor for detecting whether the rear of the thighs of an occupant are in contact with the seat pot;

[0007] The seat back is provided with a seat back sensor for detecting whether the back of the passenger is in contact with the seat back;

[0008] The inner side edge of the seat basin side wing is hinged on the seat basin through a rotating shaft, and a seat basin side wing sensor for detecting whether the outer side of the thigh of the passenger is in contact with the seat basin side wing is installed on the seat basin side wing;

[0009] The inner side edge of the backrest side wing is hinged to the seat back through a rotating shaft, and a backrest side wing sensor for detecting whether a body part of an occupant is in contact with the backrest side wing is installed on the backrest side wing;

[0010] The seat occupancy sensor, sitting upright sensor, backrest sensor, seat basin side wing sensor, and backrest side wing sensor are all connected to the whole chair intelligent controller;

[0011] The flipping movement of the seat basin side wings and the flipping movement of the backrest side wings are both completed by controlling the transmission assembly driven by the motor, and the motor is connected to the intelligent controller of the whole chair.

[0012] The transmission assembly comprises: a screw, a screw support seat, a nut and a push rod, one end of the screw is mounted on the output shaft of the motor through a coupling, and the other end of the screw is mounted in the screw support seat through a bearing;

[0013] The screw rod support base is respectively fixedly mounted on the seat basin below the seat basin side wings and on the seat back below the backrest side wings;

[0014] The nut is connected to the screw rod by threads, and the top end of the nut is hinged to one end of the push rod;

[0015] The other end of the push rod is hinged on the hinged edge of the lower plate surface of the seat basin side wing away from the seat basin side wing or is hinged on the hinged edge of the lower plate surface of the backrest side wing away from the backrest side wing.

[0016] The motors are two motors with dual output functions, and the two motors are respectively fixedly mounted on the seat pan and the seat back through motor fixing brackets.

[0017] As a preferred embodiment of the present invention, the seat occupancy sensor, the sitting upright sensor, the backrest sensor, the seat basin wing sensor, and the backrest wing sensor are all thin film pressure sensors.

[0018] When the whole chair intelligent controller receives the sensing signals from the seat occupancy sensor, the sitting upright sensor, and the backrest sensor at the same time, it determines that the occupant is in the best sitting position, and the whole chair intelligent controller controls the two motors to start, respectively driving the seat basin side wings and the backrest side wings to flip inward along the rotation axis;

[0019] When the whole chair intelligent controller receives the sensing signal from the seat basin side wing sensor, it determines that the seat basin side wing has come into contact with the passenger, and controls the motor on the seat basin to reverse, so that the seat basin side wing rotates a certain angle, and then the motor on the seat basin stops running, ensuring the comfort of the passenger's legs;

[0020] When the whole chair intelligent controller receives the sensing signal from the backrest side wing sensor and determines that the backrest side wing has come into contact with the passenger, the whole chair intelligent controller controls the motor on the seat back to stop running;

[0021] When the whole chair intelligent controller cannot receive the sensing signals from the seat occupancy sensor, sitting upright sensor and backrest sensor at the same time, it determines that the occupant wants to leave the car seat. The whole chair intelligent controller controls the two motors to start, driving the seat basin side wings and backrest side wings to flip outward along the rotating axis and return to their original positions. Then the motors stop running.

[0022] As a preferred embodiment of the present invention, when a passenger sits on the car seat, first the buttocks fall into the seat basin, and the seat occupancy sensor generates a sensing signal due to the buttocks exerting a certain pressure on the seat occupancy sensor, and the seat occupancy sensor transmits the sensing signal to the whole chair intelligent controller;

[0023] When the passenger's buttocks fall into the seat basin, the passenger will then relax his legs, causing the back of his thighs to be placed in the seat basin. Since the thighs exert a certain pressure on the sitting alignment sensor, the sitting alignment sensor generates a sensing signal, which is then transmitted to the intelligent controller of the entire chair.

[0024] When the passenger's legs are relaxed and the back of the thighs are placed in the seat basin, the passenger will then relax the upper body and lean the back against the seat back. As the body exerts a certain pressure on the backrest sensor, the backrest sensor generates a sensing signal, which is then transmitted to the intelligent controller of the entire chair.

[0025] When the whole chair intelligent controller receives the sensing signals from the seat occupancy sensor, the sitting upright sensor, and the backrest sensor at the same time, it determines that the passenger has reached a comfortable sitting posture. At this time, the whole chair intelligent controller controls the two motors to start at the same time;

[0026] When the motor on the seat basin is started, it drives the screw rod to rotate, and the nut moves outward under the rotation of the screw rod. Since the inner side of the seat basin wing is hinged to the seat basin through the rotating shaft, and the top end of the nut is hinged to the push rod, and the other end of the push rod is hinged to the lower plate surface of the seat basin wing, the push rod pushes the seat basin wing to the inside along the rotating shaft.

[0027] When the motor on the seat back is started, it drives the screw rod to rotate, and the nut moves outward under the rotation of the screw rod. Since the inner side of the backrest wing is hinged to the seat back through the rotating shaft, and the top end of the nut is hinged to the push rod, and the other end of the push rod is hinged to the lower plate surface of the backrest wing, at this time, the push rod pushes the backrest wing to flip inward along the rotating shaft;

[0028] When the whole chair intelligent controller receives the sensing signal from the seat basin side wing sensor, it determines that the seat basin side wing has contacted the sides of the thighs of the occupant, and controls the motor on the seat basin to reverse, so that the seat basin side wing rotates a certain angle, and then the motor on the seat basin stops running to ensure the comfort of the occupant's legs;

[0029] When the whole seat intelligent controller receives the sensing signal from the backrest side wing sensor, it determines that the backrest side wing has contacted the two sides of the passenger's body, and the whole seat intelligent controller controls the motor on the seat back to stop running;

[0030] When the whole-chair intelligent controller cannot receive the sensing signals from the seat occupancy sensor, the sitting upright sensor, and the backrest sensor at the same time, it is determined that the passenger wants to leave the car seat, and the whole-chair intelligent controller controls the two motors to start;

[0031] When the motor on the seat basin is started, it drives the screw rod to rotate in the opposite direction, and the nut moves inward under the rotation of the screw rod. Since the inner side of the seat basin wing is hinged to the seat basin through the rotating shaft, and since the top end of the nut is hinged to the push rod, and the other end of the push rod is hinged to the lower plate surface of the seat basin wing, at this time, the push rod pushes the seat basin wing to flip outward along the rotating shaft and return to its original position, and the motor on the seat basin stops running;

[0032] When the motor on the seat back is started, it drives the screw rod to rotate in the opposite direction, and the nut moves inward under the rotation of the screw rod. Since the inner side of the backrest wing is hinged to the seat back through a rotating shaft, and the top end of the nut is hinged to the push rod, and the other end of the push rod is hinged to the lower plate surface of the backrest wing, at this time, the push rod pushes the backrest wing to flip outward along the rotating shaft and return to its original position, and the motor on the seat back stops running.

[0033] The beneficial effects of the present invention are as follows:

[0034] (1) The intelligent automobile seat wing adjustment device provided by the present invention has an intelligent controller for the whole chair that intelligently determines whether the occupant has reached a comfortable sitting posture by simultaneously receiving the sensing signals of the seat occupancy sensor, the sitting alignment sensor, and the backrest sensor on the pressure of different parts of the human body. The intelligent controller for the whole chair controls the motor to start, and drives the seat basin side wings and the backrest side wings to flip inward along the rotation axis respectively; when the legs of the occupant come into contact with the seat basin side wings, the intelligent controller for the whole chair controls the motor on the seat basin to reverse, so that the seat basin side wings rotate a certain angle, and then the motor on the seat basin stops running, thereby ensuring the comfort of the occupant's legs; when the body of the occupant comes into contact with the backrest side wings, the intelligent controller for the whole chair controls the motor on the seat back to stop running, so as to provide the occupant with an appropriate sense of wrapping and improve the riding comfort.

[0035] (2) The intelligent car seat side wing adjustment device provided by the present invention determines that the passenger wants to leave the car seat when the entire chair intelligent controller cannot simultaneously receive the sensing signals emitted by the seat occupancy sensor, the sitting upright sensor, and the backrest sensor. The entire chair intelligent controller controls the two motors to start and respectively drive the seat basin side wings and the backrest side wings to flip outward along the rotation axis to return to their original positions, thereby making it convenient for the passenger to leave the car seat and also convenient for the next passenger to sit in the car seat.

[0036] (3) The intelligent car seat side wing adjustment device provided by the present invention has a simple structure. When working, the motor is started, the screw rod rotates, and the nut moves on the screw rod. Since the inner side edges of the seat basin side wings and the inner side edges of the backrest side wings are respectively hinged to the seat basin and the seat back through a rotating shaft, and since the top end of the nut is hinged to the push rod, and the other end of the push rod is hinged to the lower plate surface of the seat basin side wing / the lower plate surface of the backrest side wing, the push rod pushes the seat basin side wing / the backrest side wing to flip inward along the rotating shaft, which meets the different requirements of passengers on the degree to which the car side wings cover the body, and can improve the comfort of the car seat.
