As shown in Fig. 24 be pressure detecting sensor, 12 be flexible soft direction indicators cover material, and pressure perceives sensing
Device 4 uses material that is soft and having certain elasticity, can be close to the surface of steering wheel, will not loosen, can so cover
Use on the steering wheel.In use, by pressure detecting sensor 4 on vehicle steering；Lockable mechanism is installed at steering wheel
Lower section；Power supply above warning circuit controller and alarm horn switch are opened, hydraulic pump power switch is opened.
As shown in figure 3, switch I is defined as the switch of power supply, when power key, to press lamp bright；Switch II is defined as opening for alarm bell
Close, be defaulted as opening, it is bright for lamp when depressed, it is alarm bell failure.Pressure detecting sensor selects suitable model, is preferably with
Temperature-compensating, because environment inside car is complicated, and holding can also change temperature to influence the accuracy of sensor for a long time, adopt
Preferably detection voltage it can be changed with bridge circuit.Because the voltage of sensor is smaller, so needing amplifying circuit, sense
In addition vehicle condition complexity can produce interference for the transmission of device, and amplifier is also exaggerated noise, be prevented using wave filter to input shadow
False alarm is caused after sound.Safety monitoring mechanism is to make, when the non-large face machine of two hands, not export high level, mechanism will be sent
Alarm.Alarm bell act as the interrupted sound of alarm bell when any one hand leaves, and two hands leave as rapid alarm simultaneously, pacify in addition
Full mechanism for monitoring monitors that exception can send lasting alarm bell.
Power supply can select to can also be used vehicle power to give tacit consent to 12v voltages using charged lithium cells, and be supplied to battery
Charge function, battery can be with dismounting and change.
As shown in figure 4, switch is defined as the switch of power supply, the break-make of hydraulic pressure pumping source is controlled, opening lamp is bright, closes lamp
Go out.A1 is the electric electric signal of left magnet switching of control magnetic valve, and a2 is the break-make electric signal of the control right electromagnet of magnetic valve, p

Steering spindle, now clamps the piezoelectric transducer inside rubber and produces piezoelectric signal, piezoelectric transducer sends position signalling to vehicle-mounted
ECU, vehicle-mounted ECU transmits a signal to special hydraulic circuit control unit, and now control change-over valve core is in middle position again, will
The pipeline of the oil inlet and outlet of hydraulic cylinder is closed respectively, and hydraulic cylinder enters pressurize stable state after clamping, keeps clamping device position
Put constant.When driver possesses steering wheel, sensor equally spreads out of pressure signal, now controls change-over valve core to be in the right side
Position, it will make the oil inlet of original hydraulic cylinder be changed into oil-out, oil-out is changed into oil inlet, therefore hydraulic push rod starts difference
Move in reverse direction, unclamp steering spindle, steering wheel is free to rotate, and when reaching diagram off working state, two clampings are performed
Device is arrived separately to guide rail positioning boss position, and now the piezoelectric transducer inside yielding rubber produces piezoelectric signal, pressure
Electric transducer sends position signalling to vehicle-mounted ECU, and vehicle-mounted ECU transmits a signal to special hydraulic circuit control unit, now again
Secondary control change-over valve core is in middle position, and the pipeline of the oil inlet and outlet of hydraulic cylinder is closed respectively, and hydraulic cylinder enters after clamping
Pressurize stable state, keeps clamping mechanism position constant.The effect of wherein yielding rubber be prevent clamping actuator return when with
The excess impact of guide rail positioning boss.
As shown in fig. 6,13 be hydraulic cylinder, 25 be reversal valve, and 26 be overflow valve, and 27 be hydraulic pump, and 24 be oil return box, this time
Oil pipe line controls two hydraulic jacks using a three position four-way directional control valve, and when steering wheel no pressure signal, sensor sends letter
Number vehicle-mounted ECU is arrived, control signal is transported to hydraulic control unit by vehicle-mounted ECU, and now hydraulic pump is started working, this moment reversal valve
In left position, hydraulic oil arrives separately at the left chamber of two hydraulic pumps from hydraulic pump, and two hydraulic push rods are moved right, and now drives clamping
Actuator is close to steering spindle respectively, compresses steering spindle, steps up state to remain such a, reversal valve is in middle position, realizes and protects
Pressure.When steering wheel pressure detecting sensor experiences pressure signal, two reversal valves are now controlled to commutate, reversal valve is in the right side
Position, two hydraulic push rods now drive clamping actuator to be respectively further from steering spindle, steering spindle are unclamped, in order to maintain two to left movement
Clamp actuator and be in farend state, now reversal valve is in middle position, realizes pressurize.Wherein overflow valve protection oil circuit.
It is not special to the present invention although above-mentioned the embodiment of patent of the present invention is described with reference to accompanying drawing
The limitation of sharp protection domain, one of ordinary skill in the art should be understood that on the basis of the technical scheme of patent of the present invention, ability
