Principle of work of the present invention is:
1, if automobile generation frontal collision, the Port1 be connected with front crash sensor in Fig. 2 has signal input, Port2, Port3, three ports such as Port4 are without incoming signal, general-purpose operation amplifier LM324 can produce signal at mouth 1 pin, 7 pin, 8 pin, 14 pin do not produce signal, signal makes Port5 by OR circuit 7432, Port9, the control signal that Port10 produces, electromagnet 3YA in control chart 3, 4YA, 5YA action, in Fig. 3 the fluid of hydraulic oil pump force feed mouth through the left position of right side two position two-way valve and the right position of right side three-position four-way valve to hydraulic actuating cylinder B epicoele, the fluid of hydraulic actuating cylinder B cavity of resorption is through the right bit stream oil sump tank of right side three-position four-way valve, hydraulic actuating cylinder B piston rod moves down, hydraulic actuating cylinder B driving automobile seat moves backward simultaneously, form the effect that passenger initiatively dodges backward, when hydraulic actuating cylinder B moves to travel switch 6YA-backward, travel switch controls electromagnet 6YA, stop oiling, piston rod stop motion, seat stop motion.
2, if automobile rear collides, the Port2 be connected with rear collision sensor in Fig. 2 has signal input, Port1, Port3, three ports such as Port4 are without incoming signal, general-purpose operation amplifier LM324 can produce signal at mouth 7 pin, 1 pin, 8 pin, 14 pin do not produce signal, signal makes Port6 by gate circuit 7432, Port9, the control signal that Port10 produces, electromagnet 3YA in control chart 2, 4YA, 6YA action, in Fig. 3 the fluid of hydraulic oil pump force feed mouth through the left position of right side two position two-way valve and the left position of right side three-position four-way valve to hydraulic actuating cylinder B cavity of resorption, the fluid of hydraulic actuating cylinder B epicoele is through the left bit stream oil sump tank of right side three-position four-way valve, hydraulic actuating cylinder B piston rod moves, hydraulic actuating cylinder B driving automobile seat travels forward simultaneously, form the effect that passenger initiatively dodges forward, when hydraulic actuating cylinder B moves forward to travel switch 5YA-, travel switch controls electromagnet 5YA, stop oiling, piston rod stop motion, seat stop motion.
If 3 automobile lefts collide, the Port3 be connected with left crash sensor in Fig. 2 has signal input, three ports such as Port1, Port2, Port4 are without incoming signal, general-purpose operation amplifier LM324 can produce signal at mouth 8 pin, 1 pin, 7 pin, 14 pin do not produce signal, the control signal that signal makes Port7 produce by gate circuit 7432, electromagnet 2YA action in control chart 2, thus hydraulic actuating cylinder A is moved right, hydraulic actuating cylinder A driving automobile seat produces motion to the right simultaneously, forms the effect that passenger initiatively dodges to the right.
If 4 automobile rights collide, the Port4 that is connected with right crash sensor in Fig. 2 has signal input, three ports such as Port1, Port2, Port3 are without incoming signal, general-purpose operation amplifier LM324 can produce signal at mouth 14 pin, 1 pin, 7 pin, 8 pin do not produce signal, the control signal that signal makes Port8 produce by gate circuit 7432, electromagnet 1YA action in control chart 2, thus make hydraulic actuating cylinder A to left movement, hydraulic actuating cylinder A driving automobile seat produces motion left simultaneously, forms the effect that passenger's first left active is dodged.
If 5 automobiles first frontal collision occur, and right side collision occurs, so automotive seat first move, backward then to left movement.
Often opening in normally open valve of the present invention, normally closed valve refers to that oil circuit is conducting under no power state, normally closedly refers to that oil circuit is obstructed under no power state.
