Embodiment
When load-carrying vehicle is freighted before starting, continuous increase along with weight, metal slide plate 103 just can moving down and constantly move down with automotive frame 101, metal slide plate 103 touches on 104 parts of the insulated column on the sensor when non-overloading, when the loading non-overloading promptly reaches cargo-carrying standard cargo capacity, the metal slide plate just in time downhill race to the junction of insulated column 104 and Bai Gang metal column 105, when automobile surpasses the cargo capacity of regulation, metal slide plate 103 just contacts with the bottom Bai Gang metal column 105 of sensor with the moving down variation of big of automobile, be normally closed contact 402 ground connection, at this moment positive source is through relay coil 501, normally closed contact 402 ground connection, relay coil 501 begins conduction, control relay 5 work, make normally closed contact 502,504 disconnect and open contact 503,505 closures, the closure of open contact 503 make buzzer siren 2 work send audible alarm; The closure of open contact 505 makes overload warning indicator lamp 3 carry out light warning; The disconnection of normally closed contact 502 makes starting relay 6 work, disconnects ignition lock and promptly disconnects starting circuit, and automobile can not be lighted a fire; The disconnection of normally closed contact 504 is not worked 11 outages of fuel feeding electromagnetic valve, promptly disconnects oil circuit; Finally make the driver can not start a car and the unloading of being forced, when being discharged to specified value, just recover normally, thereby thoroughly solve the automobile overload problem.
This annunciator has also increased the device that prevents false alarm newly; this is the disadvantage that all has of overload warning device in the past; often all be left in the basket; this point is about to reach specified value and running car can be because serious jolting cause the false alarm that the variation of relative position up and down of bridge 106 is sent sensor before and after automotive frame 101 and the automobile at this moment can make automobile flameout at the back road that jolts or when crossing deceleration strip non-overloading the time at goods; this fender guard is to utilize the designed pulse that Hall element sends when automobile is exercised at the beginning of Hall vehicle speed mileage table sensor of modern automobile to work through the processing and amplifying rear drive control relay 4 of amplifying circuit (IC-4069); normally closed contact 402 is disconnected; the signal of controlling overload sensor 1 is inoperative; that is to say when automobile travels at the beginning just can actv. to disconnect connecting of relay coil 501 and overload sensor 1, so just avoided the non-overloading running car can be at the back road that jolts or when crossing deceleration strip because serious jolting cause the false alarm that the variation of relative position up and down of bridge 106 is sent the sensor 1 that overloads before and after automotive frame 101 and the automobile make automobile flameout.
