Description of drawings
Fig. 1 is the structural representation of the vehicle launch protective gear of the utility model embodiment proposition.
Wherein, the 1-key operation, 2-always insures, 3-relay contact, 4-alarm indicator lamp; The 5-booster diode, 6-relay, 7-time delay relay, 8-starter motor, 9-cranking-motor relay; 10-time delay relay contact, 11-insurance, 12-battery main switch, 13-diode.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined model utility purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment, the embodiment and the working principle of the vehicle launch protective gear that proposes according to the utility model is elaborated.
Can know by Fig. 1; The vehicle launch protective gear that the utility model proposes comprises: key operation 1, starter motor 8, cranking-motor relay 9, battery main switch 12, time delay relay 7, diode 13, relay 6, booster diode 5, alarm indicator lamp 4, insurance 11, always insure 2.Key operation 1, starter motor 8, cranking-motor relay 9 are formed start loop, and battery main switch 12 is parallelly connected with this start loop.The input end of time delay relay 7 is connected with start loop, and the output terminal of time delay relay 7 is connected with the input end of key operation 1, and time delay relay contact 10 is arranged in the start loop.Diode 13 is arranged on the circuit that connects start loop, time delay relay 7.The input end of relay 6 also is connected with start loop, and the output terminal of relay 6 is parallelly connected with the output terminal of time delay relay 7; Booster diode 5 is arranged on the circuit that connects relay 6, start loop.Alarm indicator lamp 4 is arranged on the circuit of the input end that connects relay 6, time delay relay 7 and key operation 1, and relay contact 3 is connected with alarm indicator lamp 4.Insurance 11 is connected in the start loop of being made up of key operation 1, starter motor 8, cranking-motor relay 9, time delay relay contact 10.Total insurance 2 is connected in the way circuit of being made up of key operation 1, battery main switch 12, starter motor 8, cranking-motor relay 9, time delay relay contact 10, insurance 11.
When vehicle launch, key operation 1 is pushed the START shelves from the ON shelves, the coil of cranking-motor relay 9 is connected, make contact, vehicle launch; Booster diode 5, relay 6, diode 13, time delay relay 7 energisings simultaneously, relay contact 3 closures, alarm indicator lamp 4 is bright.Behind the vehicle launch, key operation 1 is return the ON shelves from the START shelves, the coil of relay 6, time delay relay 7 breaks off, and then relay contact 3 breaks off, and alarm indicator lamp 4 extinguishes.If key operation 1 surpasses the time that time delay relay 7 is set in the time of START shelves, then time delay relay contact 10 automatic disconnections, promptly the start loop of starter motor 8 is disconnected, and has realized the protection to starter system.If after key operation 1 was return the ON shelves from the START shelves, alarm indicator lamp 4 did not extinguish, and explains that then starting system or time delay relay 7 break down, this moment, the driver needed deenergization main switch 12 immediately, searched fault, overhauled.
