It spends, and judges the inclined direction of chair with this, all around four direction can be parallel on the basis of the direction on ground seat
Reference value.
There is pressure sensor by the basis rest in chair legs, the pressure that chair legs are applied to residing ground can be detected
Power, when chair is normally put, each chair legs are consistent substantially to the pressure on ground.Once there is external force application that chair is caused to incline
Tiltedly, then chair support leg to the pressure that ground applies is unbalanced at this time, when external force is larger, such as one four, five years old
For child against chair back to layback, the support leg closer with back can be more than the pressure in another direction to the pressure on ground
Power can equally judge the inclined direction of chair accordingly.
It is set in data analysis module and has stored basic with reference to assessed value, chair when static vacant with chair in advance
Reference value on the basis of the pressure of leg, when someone is seated or has weight to be placed on chair, if the pressure of chair leg is basic
Unanimously, it can be determined that chair does not have run-off the straight；Once the pressure value of chair legs is uneven, or when the larger difference of generation, can
To judge that chair has inclination.

Outer layback or pushchair that chair is put, lead to chair run-off the straight, it is also possible to have external force to touch chair and bring it about
Slope trend；In this case, the support force that control auxiliary support mechanism is provided to chair need not be large, the support force of application
The weight of support chair itself enough.
2, when detecting the variation at angle of inclination, the pressure value in the section chairs leg on ground is simultaneously supported than vacant
There are many Shi Zengjia, that is, exceed the pressure threshold of setting, judge to carry weight or people on chair at this time, and because crank makes chair
Sub- run-off the straight, such case is than relatively hazardous, for example may be to have child to be rocked on chair or weight places shakiness causes
Chair tilts；In this case, the support force to chair offer needs sufficiently large, is provided centainly with controlling auxiliary support mechanism
The overhang of distance, so that chair is pushed to horizontality.
As shown in figure 5, the signal pre-processing module can be by the A/D converter of setting, the simulation received is believed
Number be converted to the digital signal identified for data analysis module；Meanwhile in order to reduce the noise jamming of signal, improving the spy of signal
Precision is surveyed, the signal pre-processing module may also include signal amplifier and filter, for exporting signal acquisition module
Signal be amplified and be filtered.
In order to realize the support function of above-mentioned auxiliary support mechanism, as shown in fig. 6, the auxiliary support mechanism in the present embodiment
Including：Cylinder 5, air-leg 6, engine (not shown), transmission shaft 7 and two rotating servo motors 8；The transmission shaft 7
Each one rotating servo motor 8 of connection in both ends, two rotating servo motors 8 are fixed on the side wall of two adjacent chair legs,
The cylinder 5 is sheathed on the centre of transmission shaft 7, and the power intake of the cylinder 5 is connect with engine, power output
End is connect with air-leg 6, and the end of the air-leg 6 is equipped with the pedestal 9 for being used to support ground, rotating servo electricity
Machine 8 and the signal input part of engine are all connected with drive module, and the drive control of module driven.
The four direction of chair can add the auxiliary support mechanism of above structure (before and after illustrating only chair in Fig. 1
Two auxiliary support mechanisms), it is driven by control motor.Data analysis module receives the detection data that detection device is sent
Afterwards, inclined direction and the angle of inclination of chair are analyzed, and calculates the elongation and rotation angle of air-leg 6 on this basis
Degree, provide support force from the inclined direction of chair prevents chair from overturning to support chair.According to the size of support force, can drive
Cylinder 5 of taking offence is further added by active force of corresponding size to air-leg 6, so that chair is pushed to horizontal positioned state.
Embodiment two
Chair in the present embodiment equally includes chair body 1, pressure sensor 2, heeling condition monitoring shown in Fig. 1
Device 3, central controller (not shown) and auxiliary support mechanism 4.With the Chair structure in embodiment one the difference is that：This reality
The heeling condition monitor 3 applied in example uses displacement sensor；As shown in fig. 7, being both provided in the corner on 1 each side of chair body
Displacement sensor, the displacement sensor incude the displacement of the lines of its position in the spatial triaxial coordinate system of setting.
Using multiple displacement sensors chair corner location setting signal mark point, when the position of chair or state are sent out
When changing, then the spatial position of signal mark point can be driven to change, data analysis module will be after change in location at this time
Each signal mark point connects, and signal mark point comparison corresponding with when static condition can simulate the current position of chair
State shows the current spatial position of chair.
As shown in figure 8, the central controller in the present embodiment includes：Signal acquisition module, signal pre-processing module, data
Analysis module and drive module；
The signal acquisition module is used to acquire pressure sensor 2 and the inductive signal of displacement sensor output；
The signal pre-processing module is used to pre-process inductive signal, what generation was identified for data analysis module
Signal；
The displacement of the lines of each displacement sensor is built the heeling condition image of chair body 1 by the data analysis module,
And the heeling condition image is compared with the horizontality image of record to rotational angle and rotation to obtain chair body 1
Direction, the rotational angle of chair body 1 is compared with the angle threshold of setting, further will branch when beyond angle threshold
It supports each chair legs pressure data in ground to be compared with the pressure threshold of setting, exceed in the pressure data of section chairs leg
When pressure threshold, by drive module drive 1 inclined direction of chair body on auxiliary support mechanism 4 rotate outward and extend to
Ground, and the auxiliary support mechanism 4 landed is driven further to extend, it is driven after chair body 1 is pushed to horizontality
Auxiliary support mechanism 4 resets；The rotation angle of auxiliary support mechanism 4 is identical as the rotational angle of ontology.
Chair is stood into the space coordinate of signal mark point when placing as reference value, once the state of chair or
When position changes, the spatial value of corresponding position signal mark point can also change.Position when chair or state
When changing, the spatial value of current each signal mark point is calculated by data analysis module, and is placed with standing
When mark point coordinate value compared, the current of chair is drawn up according to the comparison Numerical-Mode of current each position signal mark point
Spatiality, so as to calculate the inclined direction and deviation angle of chair.
In addition, in order to realize that the support function of above-mentioned auxiliary support mechanism, the auxiliary support mechanism in the present embodiment are same
Using structure shown in fig. 6.
There are following two situations in the analysis of detection project：
1, when detecting that chair heeling condition image is subjected to displacement variation, the section chairs leg in ground is simultaneously supported
Pressure value than it is vacant when increase less, i.e., without departing from the pressure threshold of setting, judge at this time on chair without carrying people or weight,
It may be the outer layback put in chair by people or pushchair, lead to chair run-off the straight, it is also possible to there is external force to touch
Chair brings it about slope trend；In this case, the support force that control auxiliary support mechanism is provided to chair need not be large,
The support force of application supports the weight of chair itself enough.
2, when detecting that chair heeling condition image is subjected to displacement variation, the section chairs leg in ground is simultaneously supported
Pressure value than it is vacant when increase very much, that is, exceed the pressure threshold of setting, judge to carry weight or people on chair at this time, and because
Crank makes chair run-off the straight, and such case is than relatively hazardous, for example may be to have child to be rocked on chair or weight
Placing shakiness causes chair to tilt；In this case, the support force to chair offer needs sufficiently large, to control Auxiliary support
Mechanism provides the overhang of certain distance, so that chair is pushed to horizontality.
It should be noted last that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting.Although ginseng
It is described the invention in detail according to embodiment, it will be understood by those of ordinary skill in the art that, to the technical side of the present invention
