Background technology
Fig. 1 is the circuit diagram of the automobile-used power supply that in engineering machinery vehicle, uses in the prior art, comprises storage battery E, is used to control the key switch S1 and the relay K 1 of car load power supply state, and the open contact anode of relay K 1 connects other consumers.Wherein normalizing electricity equipment 1 generally is the equipment that is used to play supervisory function bit, thus need uninterrupted duty, therefore by storage battery E continued power.Other consumers then are when needs use, closed key switch S1, and the open contact of relay K 1 is closed thereby the coil of relay K 1 powers on, thereby working power is provided for other consumers.But because the engineering machinery vehicle general purpose hauling time is longer, the shortest also had about a week, and length can reach the several months, and during transportation normalizing electricity equipment 1 is in running order always, the electric energy of battery consumption.Though normalizing electricity equipment 1 usefulness electrical power consumed is less, also can cause accumulator electric-quantity to exhaust after the overlong time, so storage battery does not have electricity when causing vehicle to transport to the scene, car load can't be worked, and the storage battery that needs more renew again could recover normal operation, brings inconvenience.
The utility model content
The purpose of the utility model provides a kind of automobile-used power supply and construction machinery and equipment that can address the above problem.
The automobile-used power supply that the utility model provides comprises key switch, relay, storage battery; Also comprise switch; The positive pole of storage battery is connected to an end of the coil of relay in order via switch and key switch, the other end ground connection of the coil of relay, and the negative terminal of the open contact of relay is connected to the point of connection place between switch and the key switch; And is connected with the power supply of normalizing electricity equipment is anodal, the power supply negative pole of normalizing electricity equipment is connected also ground connection with the negative pole of storage battery.
The utility model also provides a kind of construction machinery and equipment, comprises the automobile-used power supply that normalizing electricity equipment and the utility model provide.
The utility model has been through having increased a switch in the feed circuit to normalizing electricity equipment in automobile-used power supply, thereby in the transportation of construction machinery and equipment, can this switch be broken off, and make storage battery not to normalizing electricity power devices, do not cause electric quantity consumption.And after being transported to the scene, can closed this switch, energising is to guarantee the normal operation of normalizing electricity equipment.In the time of can avoiding long period transportation through the technical scheme of the utility model accumulator electric-quantity is exhausted, effectively simple.In addition, the technical scheme that provides of the utility model can also be avoided the electric leakage of storage battery.
Other feature and advantage of the utility model will partly specify in the specific embodiment subsequently.
Description of drawings
Accompanying drawing is the further understanding that is used to provide the utility model, and constitutes the part of specification sheets, is used to explain the utility model with the following specific embodiment, but does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the circuit diagram of the automobile-used power supply that uses in the prior art;
Fig. 2 is the circuit diagram of the automobile-used power supply that provides according to the utility model;
Fig. 3 is the circuit diagram of the automobile-used power supply that provides of the preferred implementation according to the utility model.
The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
As shown in Figure 2; The automobile-used power supply that the utility model provides comprises key switch S1, relay K 1, storage battery E; Also comprise switch S 2; The positive pole of storage battery E is connected to an end of the coil of relay K 1 in order via switch S 2 and key switch S1, the other end ground connection of the coil of relay K 1, and the negative terminal of the open contact of relay K 1 is connected to the point of connection place between switch S 2 and the key switch S1; And is connected with the power supply of normalizing electricity equipment 1 is anodal, the power supply negative pole of normalizing electricity equipment 1 is connected also ground connection with the negative pole of storage battery E.
Storage battery E, relay K 1, key switch S1 can adopt various structures of the prior art, all do not influence the enforcement of the utility model.
Wherein said switch S 2 can be knife switch, can have two positions of ON and OFF, wherein in transportation, this switch S 2 is placed the position of OFF; Switch S 2 is broken off; To 1 power supply of normalizing electricity equipment, consumed power is not avoided the unnecessary loss of storage battery E to storage battery E.And when 1 work of needs normalizing electricity equipment, this switch S 2 is placed the position of ON, and switch S 2 closures, storage battery E recovers the power supply to normalizing electricity equipment 1, and normalizing electricity equipment can be worked for 1 this moment, the mode of operation of monitoring car load.
And when the work of other consumers of needs, switch S 2 being placed the position of ON, other operations still are the same with prior art; Operation key switch S1 is with the path between the coil of closed storage battery E and relay K 1; Make the coil of relay K 1 power on, open contact is closed, at this moment; Other consumers that are connected the open contact anode are powered, can normal operation.
