In addition, when the people leaves seat support, also trigger control circuit energising and start power source and provide power after inductor is sensed to push-pull mechanism, push-pull mechanism pulling backrest moves backward, returns to the original default position.
Wherein, power source can adopt stepper motor.
Wherein, the control circuit power supply can be a battery.
In addition, a kind of seat control system, it comprises:
Inductor, the construction of switch that receives said inductor triggering, the control circuit that links to each other with said construction of switch, the power source that links to each other with said control circuit and the push-pull mechanism that links to each other with said power source; Said push-pull mechanism links to each other with said backrest; Wherein on seat support, take man-hour; It is closed that inductor is sensed back trigger switch structure, and making the control circuit energising and starting power source provides power to push-pull mechanism, and push-pull mechanism pulling backrest moves forward; Prop up the people back of the body when being obstructed at backrest, control circuit outage and locked current location.
In addition, when the people leaves seat support, also trigger control circuit energising and start power source and provide power after inductor is sensed to push-pull mechanism, push-pull mechanism pulling backrest moves backward, returns to the original default position.
Wherein, power source can adopt stepper motor.
Wherein, the control circuit power supply can be a battery.
Compared with prior art, the utlity model has following beneficial effect:
The seat of the utility model is taken man-hour on seat support, inductor is sensed the back trigger switch, and control circuit energising and startup power source provide power to push-pull mechanism; Push-pull mechanism pulling backrest moves forward, and props up people's back of the body when being obstructed at backrest, and control circuit outage and locked current location need not people's hand control; Automatically induction is regulated, and can be through the direct current drive running, and the detachable battery box is safe and efficient laborsaving; Have mobility concurrently, its structural safety is simple, realizes that price is low; Structural safety is simple, can lock at any time, and crash-protective characteristics is strong.
Description of drawings
Fig. 1 is the overall schematic of a specific embodiment seat of the utility model seat.
Fig. 2 is an embodiment sketch map of the power supply power supply of the utility model control circuit components of system as directed;
Fig. 3 is the sketch map that the utility model specific embodiment seat is realized position adjustments automatically;
Fig. 4 is the principle schematic of the utility model specific embodiment push-pull mechanism pulling backrest.
The specific embodiment
With reference to figure 1, seat comprises backrest 1 and seat support 2 in the utility model, and seat support 2 is provided with inductor; For example places such as 3 are provided with in the position, mainly are arranged on the people and are sitting in each position on the seat support, can on seat support, arrange comprehensively; Also can concentrate setting, in addition, the push-pull mechanism that can be provided with the switch that triggered by inductor, the control circuit that links to each other with said switch, the power source that links to each other with said control circuit on seat support 2 chassis and link to each other with said power source; These parts can be concentrated setting in position 4, with reference to figure 2, for the control circuit part; For example can concentrate containment circuit board 41, battery 44 etc. through plastic casing 45; In order to save electric power and to be convenient to control, also power switch 42 can be set, and supply socket 43.
And push-pull mechanism links to each other with said backrest in the such scheme; With reference to figure 3, on seat support, take man-hour, inductor (is for example sensed back trigger control circuit energising; Trigger switch is closed and then make the control circuit energising) and start power source and provide power to push-pull mechanism 5; S1's push-pull mechanism 5 pulling backrests moves forward from the position, for example passes through the rotation of hinge folder 51 in the present embodiment, makes backrest prop up the people and carries on the back when being obstructed (during the S2 of position); Control circuit outage and locked current location, thus realize the power seat position.
In addition; When the people leaves seat support, but also trigger control circuit energising and start power source and provide power after inductor is sensed to push-pull mechanism, and push-pull mechanism pulling backrest moves backward; Return to the original default position, promptly recovering initial position does not need the staff adjustment yet.
With reference to figure 4; Realize the sketch map of push-and-pull for push-pull mechanism among embodiment of the utility model; In shell 55, include motor 54 and be fixed on the support 52, motor 54 links to each other with the screw rod 56 of push-pull mechanism through connector 53; Shaking the head of the push rod 57 of push-pull mechanism and backrest 58 links to each other, thereby the push rod of push-pull mechanism can promote backrest and moves forward or backward under the drive of motor 54.
Need explain that it can be to sit to wrap at chair induction point is set that inductor is set on the seat support in the such scheme, can on induction point, add iron plate when specifically realizing to increase induction region.On chair, take man-hour, when induction point received certain pressure, the meeting touch switch was closed, the control circuit energising, and the control power source is such as motor or stepper motor entry into service, and the push rod of push-pull mechanism moves backrest forward.And when backrest is obstructed, power source, for example stepper motor stall produces corresponding signal to control circuit, and control circuit is outage and locked current location automatically.
In addition, the pressure on seat support weakens, when for example the people leaves the seat; Meeting trigger switch after inductor is sensed; Produce a signal and give control circuit, control circuit is switched on again, and the control power source for example push rod of stepper motor promotion push-pull mechanism makes backrest reset into the home position.During concrete the realization, can so go round and begin again and carry out the adjusting of seat back positions automatically.
Need explanation; The seat support chassis is fixing in the installation site of chair seat bag bottom; And make the rear portion give prominence to chair seat bag certain distance; Add the special radian of the ergonomic of backrest, can not only adjust when backrest moves forward through the special radian of backrest ergonomic and sit deeply, can solve different users's waist position height difference simultaneously; Promptly corresponding different users's different heights and corresponding comfort is provided to greatest extent can be combined into the movement locus of ergonomic.And with reference to figure 2, above-mentioned control circuit can adopt dc source, for example battery 44 power supplies, and safety and mobility and adaptability are high.Battery case is detachable, and separation of charged also can be provided with power switch 42, saves electric power, and ability fixed seat position of back need not each replacing, avoids maloperation simultaneously.
In addition, it is mobile that seat can be provided with the wheel realization in the utility model that also need explain, uses the vapour bar can carry out the step-less adjustment height, and can direction of rotation.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
