Specific embodiment
1-6 below in conjunction with the accompanying drawings is described further the technical solution used in the present invention.
As shown in Figure 1, a kind of aiding upright chair for closet of hydraulic control, including：
Hydraulic device 3, piezoelectric force transducer 4, the first hydraulic push rod 7, the second hydraulic push rod 9, supporting rod 6, tripod
5, wherein, the first hydraulic push rod 7 and the second hydraulic push rod 9 are mounted on seat panel in the following, hydraulic device 3 is mounted on under-seat
Fagging on.
As shown in Fig. 2, piezoelectric force transducer 4 be mounted on seat panel 1 on, piezoelectric force transducer 4 above covered with
Seat cushion, the second hydraulic push rod 9 support 1 front end of seat panel, and the first hydraulic push rod 7, supporting rod 6 and tripod 5 are common
Support 1 rear end of seat panel, tripod 5 and supporting rod 6 can make the angle of seat overturning bigger, the first hydraulic push rod 7 and the
Two hydraulic push rods 9 are connected among underground, and pressure is provided by the hydraulic device 3 below seat.
Plunger 7-1 one end of first hydraulic push rod 7 is linked by pin 7-2 and the A ends of tripod 5, and tail end passes through 16 chain of pin
It connects and links together with seat base 8.6 one end of supporting rod is linked by pin 16 and the B ends of tripod 5, and the other end passes through pin 16
Link is linked together with seat base 8.The C-terminal of tripod 8 is linked in 1 rear end of seat panel by pin 16.Wherein A ends are three
That one end that corner bracket 5 is connected with seat panel 1, B ends are that one end that tripod 5 is connect with supporting rod 6, and C-terminal is tripod 5
That one end being connected with the plunger 7-1 of the first hydraulic strut 7.Plunger 9-1 one end of second hydraulic push rod 9 passes through pin 9-2 chains
It connects and is linked together with seat base 8, the tail end of the second hydraulic push rod 9 is linked by pin 16 to be linked at 1 forepart of seat panel
Together.
Fluid enters the first hydraulic push rod 7, pushes the first plunger 7-1 movements, so as to be lifted 1 rear end of seat panel.The
Input of the hydraulic oil of one hydraulic push rod 7 output after restricting element 10 and overflow valve 15 depressurize as the second hydraulic push rod 9
Hydraulic oil pushes the second plunger 9-1 movements, so as to which 1 front end of seat panel be pushed to rise.
Since the first hydraulic push rod 7 starts prior to the second hydraulic push rod 9, in the limitation of overflow valve 15 and restricting element 10
Under, the input pressure and input flow rate of the second hydraulic push rod 9 are less than the output pressure and output flow of the first hydraulic push rod 7, because
The Uplifting amount of this 1 rear end of seat panel is more than the Uplifting amount of 1 front end of seat panel, so as to assist patient stand.
When patient's sitting, the piezoelectric force transducer 4 of seat experiences pressure change, and the pressure change is by conversion electricity
Input current after road, amplifying circuit and CPU processing as proportional pressure valve 12, so as to control the overflow pressure of whole system
Power.
As shown in figure 3, the present invention gives the aiding upright chair for closet course of work of hydraulic control, its step are as follows：
Step 1:During patient's sitting, the piezoelectric force transducer of seat installation experiences pressure, when patient takes, causes
Resistance variations.
Step 2：Using 12v DC power supplies as bridge excitation power supply, when voltage dependent resistor changes, cause output electricity
The variation of pressure.
Step 3：The filtered circuit sampling of output voltage keeps amplifying the output voltage by amplifying circuit later.
Step 4：Preset parameter makes data input CPU, is converted into digital quantity progress D/A by the calculation process to parameter
Analog signals.
Step 5：The analog signal is again after ratio enlargement, and output is controlled to adjust again by 4 potentiometers, Ran Houzai
Electronics amplification board is output to by corresponding wire connection terminal.
Step 6：The control signal of computer output is input into signal as electronics amplification board, by shaping, compare, feed back,
Amplification and isolated transmission are toward control pliotron, then control ratio pressure valve coil, so as to control hydraulic system pressure.
Step 7：In pressure input hydraulic pressure system by proportional pressure valve control, provided not for the patient of different weight
With the hydraulic thrust of size.
As shown in figure 4, the present invention has also been devised as above underground, three-position four-way electromagnetic directional valve 14 and overflow valve 15,
Throttle valve 10, proportional pressure valve 12, the first hydraulic push rod 7 and the second hydraulic push rod 9 composition hydraulic control lines.Because first
The load-bearing of hydraulic push rod 7 is bigger than the load-bearing of the second hydraulic push rod 9, so the oil outlet in the first hydraulic push rod 7 is connected to one
A overflow valve 15 and throttle valve 10, to control pressure and flow into the second hydraulic push rod 9.Proportional pressure valve 12 is used as overflow
Valve controls the pressure into system, and for proportional pressure valve 12 here as overflow valve, oil pressure relief specific thrust is big by 5%, should
Place's pressure is set by CPU.The proportional pressure valve 12 is come the pressure size of control system according to the size of current into system.Chair
Face is provided with piezoelectric force transducer 4, and after sensor 4 experiences patient's weight, resistance changes so as to cause electric bridge
The variation of output voltage is sent into CPU after the filtered circuit of output voltage, amplifying circuit processing and carries out A/D conversions, then exports
Input current of the electric current as proportional pressure valve 12, so as to the variation of control system pressure.
As shown in figure 4, diaphragm type force snesor 4 is installed on seat panel.When patient takes, force snesor 4 monitors
To signal intensity, cause the variation of tabletting resistance R1, Ue is as bridge excitation power supply, when the resistance of resistance strain gage R1 becomes
During change, lead to the variation of output voltage Uo.Normal conditions lower sensor output signal is all very faint, and filtered circuit is needed to adopt
Sample is amplified after keeping by amplifying circuit, the input current as proportional pressure valve 12.
Although certain features of the present invention have been illustrated and described herein, those skilled in the art will expect being permitted now
More modifications, replacement, change and equally.It should therefore be understood that the covering that is intended to of appended claims is fallen in the true of the present invention
All such modifications and changes in positive spirit.
