Description
Technical field
The present invention relates to a kind of automotive seat, especially relate to a kind of Vehicular seat device from the dynamic correction sitting posture.
Background technology
The design of automobile now with produce the theory that people-oriented that incorporates, guarantee the magnificent outward appearance of automobile with stable in, also on the traveling comfort of automobile, drop into a lot of technology and innovate.When the people was sitting in the automobile, seat was to contact the closest parts with human body, also was that influence is driven and ride comfort degree and the critical facility that guarantees passenger safety.Wherein, the seat of chaufeur is even more important, and comfortable and easy to operate driver seat can reduce the driver fatigue degree, reduces the incidence of fault.At present, automotive seat have had very big development in comfortable driving, set out according to each side such as chaufeur age, sex, height, builds, regulate seat and reach comfortable driving condition.But the operator's saddle of automobile is to adopt hard-wired design basically now; This just makes automobile when turning; Chaufeur influences the judgement of driver to vehicle position on actual road surface owing to the reason of self health inertia and turning centnifugal force causes health banking.Thereby buried the hidden danger of accident.
Summary of the invention
The object of the invention is exactly to provide a kind of simple in structure, circuit control principle easily from the Vehicular seat device of dynamic correction sitting posture in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme:

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of Vehicular seat device from the dynamic correction sitting posture; Comprise seat body 1, sensor 2, micro controller system 3, motor drive module 4, motor 5, belt conveyor 6, described sensor 2 is distributed in the bottom of seat body 1, and described sensor 2 is connected with micro controller system 3; Described micro controller system 3 is connected with motor 5 through motor drive module 4, and described motor 5 is connected with seat body 1 through belt conveyor 6.Described seat body 1 bottom is provided with 1 lead 11, and passes to alternating current.Described sensor 2 is an electromagnetic sensor, and this electromagnetic sensor 2 is provided with 8, many 8 electromagnetic sensors 2 in one line with 11 one-tenth 90 degree of lead, and electromagnetic sensor 2 quantity on lead both sides are identical; Treat that the garage is to bend; Seat body 1 deflects; Cause the lead 11 of seat body 1 below also to squint, the output of electromagnetic sensor 2 is also changed and this change information is sent to micro controller system 3, handle after these micro controller system 3 reception information; And drive motor drives module 4 is controlled motor 5 positive and negative rotations, the displacement deflection that motor 5 rotations take place because of turning through 1 correction of driving band 6 drive seat body.
But automotive seat are the left-right rotation formula, can rotate with the inertia and the center shaft of centnifugal force on base of turning, and the centnifugal force owing to automotive seat when automobile is gone off the curve disappears, and the seat is ajusted again, vertical and horizontal state when recovering straight way.Because sensor is only near just sending signal to micro controller system near the electrified wire; So on straight way; Lead under the seat becomes the number of sensors on plumbness and lead both sides to equate with electromagnetic sensor in one line; Sensor in the middle of promptly having only just sends signal to micro controller system, after micro controller system is received the information of sensor then, provides signal to motor-driven.At this moment motor is need not rotate on the straight way owing to being in, and that is to say that seat can not deflect, and has kept the health of navigating mate straight and upright, the look straight ahead road.
Circuit connects: with 8 electromagnetic sensors is example.8 sensors all adopt the sensor of digital quantity, promptly when near electromagnetism is logical when being worth greater than certain, sensor output signal be " 1 " (5V).The corresponding respectively Chip Microcomputer A/D0 to A/D7 that inserts of the output of 8 sensors.Single machine output end connects motor drive ic; The torque and the rotation direction of chip for driving control servomotor; When value of providing (Uc) of micro controller system during greater than some numerical value (intermediate value) motor for just changeing, otherwise then motor counter-rotating, when equating with this numerical value; In the middle of motor recovers, and keep motionless.
Device correction divides two kinds of forms: up time is proofreaied and correct, the inverse time correction, and after installing seat, these two kinds of forms automatically switch.
One, device is in the up time correcting state.Like Fig. 4, shown in Figure 5, when vehicle bent to right, because the inertia and the turning action of centrifugal force of human body, the center of gravity of human body can be partial to the left side of car.Chaufeur can be with the seat left side to pressing down so; And the unconscious too high right side of seat; The lead that same situation is positioned at bottom the vehicle seat also can be owing to inertia and turning action of centrifugal force; And in the middle of sensor, squint, the deflection left side, the sensor that at this moment is positioned at the left side is returned " 0 " by the sensor in the middle of the set.This signal constantly (for example: 01100000) the A/D port of input micro controller system; And with micro controller system in the intermediate value (binary number 00011000) set advanced relatively; Find not to be inconsistent with setting value, micro controller system as signal voltage Uc, is exported to chip for driving from the PWM ripple (supposing that dutycycle is 20%) that the Px mouth provides a setting; Chip for driving is controlled the size and the rotation direction of motor rotating torque according to the PWM ripple (being the difference of Uc) of different duty.Because what exported this moment from the Px mouth of micro controller system is the PWN ripple of 20% dutycycle, less than intermediate value 50%.Drive motor clickwise, the moment of motor left, so the belt conveyor of the connection seat on motor right side is tightened up, the belt conveyor in motor left side then loosens, state outright just force seat the right side to sinking, and then the left side of having raised seat.This and chaufeur can be cancelled out each other the seat left side to the power that presses down, make the centre of body weight of chaufeur be in all the time vertically and horizontal state.Accomplish when Vehicular turn, when going off the curve, the center of gravity of human body is by left backswing gradually, until returning to the center.In this simultaneously; The lead of vehicle seat bottom also can return to the midway location of sensor; Sensor inputs to Chip Microcomputer A/D port (sampled value is 00011000) to the numerical value of at this time sampling, and micro controller system is made comparison to the sampled value and the value (01100000) of storage before, finds that both do not wait; The PWM ripple (being 50% dutycycle) that micro controller system provides another dutycycle from the Px mouth is as signal voltage Uc; Export to chip for driving, chip for driving is reversed motor, and the power of pullling the right belt conveyor originally is released.Initial position in the middle of getting back to motor, the power of the seat that belt conveyor imposes on the motor left side and the right equates at this moment, so just ability bondsman's sitting posture is kept upright.
Two, device is in the inverse time correction.Like Fig. 6, shown in Figure 7, when vehicle was turned left, the present invention was in the inverse time correction form, and its theoretical analysis is identical with the up time correction, no longer sets forth at this.
