Abstract
The invention relates to an automobile emergency pneumatic power switch, mainly comprising a spring limiting plate, a spring, a power supply connection plate, a lead connecting plate and a power supply, further comprising a cylinder piston rod, a cylinder, a cylinder limiting plate, a hand air valve and an air reservoir. When a fire is caused by a fault of the automobile, and the main power supply cannot be cut by keys caused by a short circuit and a broken circuit of an automobile electric system, the main power supply is cut with the pressure of a compressed air in the automobile air reservoir through the cylinder to avoid heavy dangerous case if the main power supply cannot be cut in time.
Description
Technical field
What the present invention relates to is a kind of automobile emergency pneumatic power switch, be used for occurring for some reason emergencies such as the condition of a fire, automobile circuit system because of short circuit occurring or opening circuit to cut off general supply with key switch the time at automobile, utilize the pressure of automobile air storage vessel compressed air, by cylinder automobile power source is disconnected, avoid increasing the weight of dangerous situation, belong to the means of transportation field because of automobile power source can not in time cut off.
Background technology
For automobile, power supply is controlled with key switch.Promptly connect automobile power source, car electrics and engine ignitor by the screw key switch.China's patent application number 00211733.9 discloses a kind of automobile power supply switch control device, controls the joint and the cut-out of battery main switch with means of electromagnetic forces.When key switch place on-position, produce electromagnetic force and under the electromagnetic force effect, the engage contacts of battery main switch, power connection; When key switch place off-position, electromagnetic force disappears, and the contact of battery main switch disconnects, and power supply disconnects.Under normal conditions, the battery main switch controlled of electromagnetic mode can satisfy the demands.But occur emergency such as the condition of a fire, automobile circuit system for some reason at automobile because of short circuit occurring or opening circuit to cut off the electricity supply with key switch the time, can increase the weight of dangerous situation because of power supply can not in time cut off.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of automobile emergency pneumatic power switch is provided, be used for occurring for some reason emergencies such as the condition of a fire, automobile circuit system because of short circuit occurring or opening circuit to cut off general supply with key switch the time at automobile, utilize the pressure of automobile air storage vessel compressed air, by cylinder the automobile general supply is disconnected, avoid increasing the weight of dangerous situation because of automobile power source can not in time cut off.
The present invention is achieved through the following technical solutions.The present invention mainly comprises: spring limiting board, spring, power supply plate, connecting wire contact pin, power supply, it is characterized in that also comprising: cylinder piston rod, cylinder, cylinder limiting plate, hand air valve, air tank, its connected mode is: an end of spring is close to spring limiting board, the other end of spring is close to the power supply plate, the power supply plate is adjacent to two connecting wire contact pin under the effect of spring force, cylinder is between cylinder limiting plate and power supply plate, the air inlet of hand air valve one termination ventilation cylinder, the hand air valve other end is connected air tank.
When hand air valve was in on-position, the pressed gas in the air tank entered cylinder, promoted cylinder piston rod and stretched out, and with power supply plate jack-up, cut off the electricity supply.
When hand air valve was in scram position, the pressed gas in the air tank was cut off, and cylinder piston rod is withdrawn under the effect of spring force, and spring is pressed on the power supply plate in the connecting wire contact pin, energized.
The present invention has substantive distinguishing features and marked improvement.The invention provides a kind of automobile emergency pneumatic power switch, be used for occurring for some reason emergencies such as the condition of a fire, automobile circuit system because of short circuit occurring or opening circuit to cut off general supply with key switch the time at automobile, utilize the pressure of automobile air storage vessel compressed air, by cylinder the automobile general supply is disconnected, avoid increasing the weight of dangerous situation because of automobile power source can not in time cut off.

Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention mainly comprises: spring limiting board 1, spring 2, power supply plate 3, connecting wire contact pin 4, power supply 10, it is characterized in that also comprising: cylinder piston rod 5, cylinder 6, cylinder limiting plate 7, hand air valve 8, air tank 9, its connected mode is: an end of spring 2 is close to spring limiting board 1, the other end of spring 2 is close to power supply plate 3, power supply plate 3 is adjacent to two connecting wire contact pin 4 under the effect of spring 2 power, cylinder 6 is between cylinder limiting plate 7 and power supply plate 3, the air inlet of hand air valve 8 one terminations ventilation cylinder 6, hand air valve 8 other ends are connected air tank 9.
When hand air valve 8 was in on-position, the pressed gas in the air tank 9 entered cylinder 6, promoted cylinder piston rod 5 and stretched out, and with power supply plate 3 jack-up, cut off the electricity supply 10.
When hand air valve 8 was in scram position, the pressed gas in the air tank 9 was cut off, and cylinder piston rod 5 is withdrawn under the effect of spring 2 power, and spring 2 is pressed on power supply plate 3 in the connecting wire contact pin 4, energized 10.
