Description
Technical field
The present invention relates to a kind of Electric sofa clamping-proof control system.
Background technology
With the continuous improvement of living standard, Electric sofa popularizes program more and more higher as a high-grade leisure household.
But Electric sofa is in use, children or toy crushed, it is more and more to press from both sides dead case.Because, work as people
Sofa sole can be opened during rest, back is put down, whole sofa is in flat state of lying.When the people rested on sofa presses
Button control push rod makes back, sole all pack up, in this process, if children or animal enter sole region, will
In the presence of the danger being gripped to.Particularly when the elderly is recumbent on a sofa, they are slow in reacting, it is impossible to process this burst shape in time
Condition, may lead to bigger tragedy.For this situation, current some countries have been studied the anti-pinch equipment of Electric sofa
Carry out as the standard of pressure, therefore the anti-pinch device of exploitation Electric sofa turns into a very urgent thing.
The anti-pinch scheme of current Electric sofa chair is all more original, there are many limitation.Conventional anti-pinch scheme includes
It is following two：A kind of is respectively to install an anti-clamping plate in two outsides of linkage of couch.Can prevent the limbs of people from
Outside enters into the subregion of linkage.Another kind is to use the junction between the sole of couch and both sides connecting rod
The connected mode of spring and hinge.When sole shrinks encounters barrier, sole can be lifted up under the stop of barrier, make
Obtaining sole will not crush people or toy.
But both modes all Shortcomings, the first scheme only protects the subregion of linkage, for connecting rod
Other positions could not play a protective role, and can not prevent children or toy by connecting rod inner side enter linkage in；
The anti-pinch region of second scheme is also locality, for other positions, is once clipped at the connecting rod being such as connected with sole
Virgin or toy, this scheme serves arrives., still there is anti-pinch blind area in the mode that both anti-pinch schemes are combined,
Therefore or Shortcomings.

Specific embodiment
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further illustrated.These accompanying drawings are simplified signal
Figure, only illustrates basic structure of the invention in a schematic way, therefore it only shows the composition relevant with the present invention.
A kind of Electric sofa clamping-proof control system as shown in Figure 1 to 4, the anti-pinch for Electric sofa bottom section is protected
Shield, including Switching Power Supply 1, promote Electric sofa metallic support expanding-contracting action electric pushrod 2 and manipulation electric pushrod hand
Control device 3, the bottom inside that the described connection of hand controller 3 has control box 4, Electric sofa is provided with infrared induction probe 5, electricity
Capacitive sensing device 6 is provided with the rear vertical rod of dynamic sofa metallic support, the bottom of Electric sofa is provided with three or four successively
The mechanical switch 7 of arrangement, control box 4 receive infrared induction probe 5 or capacitive sensing device 6 or mechanical switch 7 detection signal and
Control the stopping action of electric pushrod 2 or counter motion.
During Electric sofa use, the several ways that human or animal enters Electric sofa sole anti-pinch region are：(1)、
When human or animal enters into sole region by sofa front, can sense that control box 4 receives infrared by infrared induction probe 5
The stopping action of electric pushrod 2 or counter motion are controlled after the signal that inductive probe 5 sends, anti-pinch protection is triggered；(2), as people or
When the skin of animal encounters the metallic support of Electric sofa, controlled after the signal that the reception capacitive sensing of control box 4 device 6 sends electronic
The stopping action of push rod 2 or counter motion, trigger anti-pinch protection；(3), when human or animal enters anti-nip by metallic support outside
Domain, but parts of skin does not encounter metallic support, if limbs can be sensed when continuing inwardly to go deep into by infrared induction probe 5, touches
Hair anti-pinch protection, when human or animal places close to sofa bottom, can encounter mechanical switch 7 and trigger anti-pinch protection.
Above is human or animal enters to need to carry out the several ways in anti-pinch protection region, using such scheme, Ke Yiyou
Effect prevents the possibility that human or animal is crushed.
Shutter is set on the side of infrared induction probe 5, to control induction region, infrared induction probe 5 to be installed to sofa
After below sole, coordinate universal regulator to adjust the sensing angle of infrared induction probe 5, meet its investigative range and require
(this mounting means, infrared sensitivity is optimal).Can also increase multiple infrared induction probes 5 to expand according to demand simultaneously
Search coverage, accordingly even when the people (or animal) of sofa bottom part down does not move, but during sofa foot plate is packed up, it is red
Outer inductive probe 5 can follow support foot plate to move so that produce relative motion between people (or animal) and infrared induction probe 5, red
Outer inductive probe 5 is able to detect that the presence of people (or animal) so as to trigger anti-pinch protection.
But because the sensing of infrared induction probe 5 has certain blind area, therefore the metallic support of whole Electric sofa is connected
Integrally, metallic support information is gathered by control box 4, once there is human or animal to touch any connecting rod of metallic support
Afterwards, control box 4 enters anti-pinch processing routine after receiving the signal that capacitive sensing device 6 sends, and opens pinch resistant functionality.It is simultaneously
Influence of the earth to metallic support is prevented, insulation foot pad is installed in metallic support bottom.
And mechanical switch 7 be then installed to sofa sole lower portion in infrared induction probe 5 and capacitive sensing device 6 sensing it is blind
Zone position.
The mode of above-mentioned triggering anti-pinch protection, the infrared induction probe 5, capacitive sensing device 6 and mechanical switch 7 of use, both
Can be used alone, it is also possible to be used in combination two-by-two, certainly it is still further preferred that in this preferred embodiment, infrared induction probe 5, electric capacity
Inductor 6 and mechanical switch 7 are used in conjunction with, such that it is able to more preferably, more fully cover investigative range, improve anti-pinch effect.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and be carried out that it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all cover within the scope of the present invention.
