Abstract
The utility model relates to a kind of engine at extreme rear passenger vehicle starting guard equipment, comprises starter motor, storage battery, 12V normally closed relay, neutral position switch, motor door magnetic induction proximity switch, vehicle ignition ST switch and fus, the battery terminal of described starter motor is connected with the positive pole of storage battery; The starting of starter motor control wiring terminal by 12V normally closed relay respectively with neutral position switch, motor door magnetic induction proximity switch, vehicle ignition ST switch is connected with fus; The other end of starter motor is connected with the negative pole of storage battery.The upper end of described 12V normally closed relay is connected with generator N point.Described fus is connected on the positive pole of storage battery.The utility model energy available protecting starter motor can not damage because of heavy burden work, avoids the generation of accidental event.
Description
Technical field
The utility model relates to auto manufacturing's technical field, is specially a kind of engine at extreme rear passenger vehicle starting guard equipment being applicable to engine at extreme rear passenger vehicle.
Background technique
Rear-engine bus needs related personnel to open the maintenance of vehicle rear motor door when engine problem, now maintenance man is away from driver's compartment, in driver's compartment, personnel can't see in engine bin that situation is as piloted engine, and the motor of running can cause very major injury to maintenance man; As vehicle makes starter motor work on gear, starter motor very easily damages because of heavy burden work; As the still passive work of starter motor after normal working of engine, starter motor is with regard to easy burn-out.Be badly in need of a kind of engine at extreme rear passenger vehicle starting guard equipment, thoroughly avoid this type of accidental event.
Model utility content
The purpose of this utility model is the shortcoming and defect overcoming prior art, provides a kind of engine at extreme rear passenger vehicle starting guard equipment of energy available protecting starter motor.
The purpose of this utility model is achieved by the following technical solution:
A kind of engine at extreme rear passenger vehicle starting guard equipment, comprises starter motor, storage battery, 12V normally closed relay, neutral position switch, motor door magnetic induction proximity switch, vehicle ignition ST switch and fus, the battery terminal of described starter motor is connected with the positive pole of storage battery; The starting of starter motor control wiring terminal by 12V normally closed relay respectively with neutral position switch, motor door magnetic induction proximity switch, vehicle ignition ST switch is connected with fus; The other end of starter motor is connected with the negative pole of storage battery.
As preferably, the upper end of described 12V normally closed relay is connected with generator N point.
As preferably, described fus is connected on the positive pole of storage battery.
The beneficial effects of the utility model are: a kind of engine at extreme rear passenger vehicle starting guard equipment energy available protecting starter motor can not damage because of heavy burden work, avoids the generation of accidental event.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is circuit structure diagram of the present utility model;
1 is starter motor, and 2 is storage battery, and 3 is 12V normally closed relay, and 4 is neutral position switch, and 5 is motor door magnetic induction proximity switch, and 6 is vehicle ignition ST switch, and 7 is fus, and 8 is battery terminal, and 9 control wiring terminal for starting, and 10 is generator N point.
Embodiment
As shown in Figure 1, a kind of engine at extreme rear passenger vehicle starting guard equipment, comprise starter motor 1, storage battery 2,12V normally closed relay 3, neutral position switch 4, motor door magnetic induction proximity switch 5, vehicle ignition ST switch 6 and fus 7, the battery terminal 8 of described starter motor 1 is connected with the positive pole of storage battery 2; The starting of starter motor 1 control wiring terminal 9 by 12V normally closed relay 3 respectively with neutral position switch 4, motor door magnetic induction proximity switch 5, vehicle ignition ST switch 6 is connected with fus 7; The other end of starter motor 1 is connected with the negative pole of storage battery 2.The upper end of described 12V normally closed relay 3 is connected with generator N point 10.Described fus 7 is connected on the positive pole of storage battery 2.
Motor door is closed under normal circumstances, now motor door magnetic induction proximity switch 5 closes, as driver wants to pilot engine, only automobile gear level need be linked into neutral (now neutral position switch closes), maneuver vehicle igniting ST switch 6 makes it closedly just can pilot engine.
When have people open motor door check motor or fix over an engine time, motor door magnetic switch 5 disconnects, in any case now start control wiring terminal 9 to be communicated with storage battery 2 positive pole, motor can not be started, and related personnel is very safe near engine bin.
When vehicle is not at neutral position state, neutral position switch disconnects, and control wiring terminal 9 can not be communicated with storage battery 2 positive pole in any case now start, motor can not be started, and starter motor 1 can not bear a heavy burden work.
After motor is started; electrical power generators causes 12V high level on generator N point 10; now 12V normally closed relay 3 work its contact disconnect; in any case now start control wiring terminal 9 to be communicated with storage battery 2 positive pole; even if operator because can not start still closed vehicle ignition ST switch 6 by perception motor away from motor; starter motor 1 still can quit work automatically, and starter motor 1 can at utmost be protected.
Above-described embodiment; a just example of the present utility model; be not for limiting enforcement of the present utility model and interest field, all technological schemes identical or equivalent with content described in the utility model claim, all should be included in the utility model protection domain.
