Abstract
The utility model relates to an automatic vehicular changeover switch with the voltage of 24V /12V, utilizing two storage batteries with the voltage of 12V to form an accumulator battery. The utility model composed of a relay and a changeover switch is characterized in that the relay is added. When the changeover switch is converted between a working end and a starting end, the two storage batteries are changed between parallel connection and serial connection for output in order to obtain the aim of automatically converting electric supply with the voltage 24V / 12V. Power-driven apparatus in a diesel vehicle have the voltage of 12V besides a starter having 24V via using the utility model, the service life of the utility model is prolonged, and operating cost is reduced.
Description
The utility model relates to the power conversion switch, more particularly, is a kind of automobile-used 24V/12V that adopts two 12V storage batterys to constitute batteries automatic alteration switch of powering.
At present, what mostly diesel vehicle adopted is the power consumption equipment of 24V, and adopts that the 12V power consumption equipment is compared, price height, of poor quality not only, and because of its voltage height, short circuit current are big, easier device and the circuit of burning out.In addition, as east wind 140 diesel vehicles, starter and generator are 24V, other power consumption equipments are 12V, under the situation that change over switch is not set, during long-distance driving charging be two storage batterys simultaneously, electricity consumption only is one of them, the result is because a storage battery is crossed and put, and another overcharges, and very easily causes battery damage.
The purpose of this utility model is to avoid existing weak point in the above-mentioned prior art, a kind of 24V/12V is provided the automatic alteration switch of powering, so that for starting with provide outside the required 24V power supply, other power consumption equipment all can obtain the 12V power supply, also promptly, other power consumption equipment can unify to adopt 12V.
The purpose of this utility model is achieved through the following technical solutions.
The utility model adopts two storage battery GB1 GB2 to constitute batteries.Feature of the present utility model is:
A, relay J 2, J3 and J4 are set.Wherein, the J2 coils from parallel connection of coils is in the start end of K switch; J3 coil and the working end that is connected in parallel on K switch after the J2 coil is connected; J4 coil and the working end that is connected in parallel on K switch after normally opened contact J3 connects.
The anodal termination starter of b, described storage battery GB1 M, negative pole end one tunnel is often opened contact J4-1 ground connection, and the positive terminal that contact J2 meets storage battery GB2 is often opened on another road.The positive terminal one tunnel of described storage battery GB2 is often opened contact J4-2 and is met starter M, and another road connects the center-side of K switch, GB2 negative pole end ground connection.
The utility model is to be realized by the relay and the change over switch that are arranged in the circuit.When change over switch between " work " and " startup " end when changing, the conversion between " parallel connection " and " series connection " of two 12V storage batterys is exported, thereby reaches the purpose of the automatic conversion of powering.
Compared with the prior art, the utlity model has following advantage:
The utility model is simple in structure, reliable operation, volume is little, cost is low, can finish the automatic conversion of 24V and 12V power supply, and, because its contact resistance little (contact voltage drop of whole device is no more than 0.1V), therefore, can substitute original mains switch simultaneously.Use the utility model can make power consumption equipment in the diesel vehicle except that starter 24V, other is 12V, thereby makes the power consumption equipment of diesel vehicle general, unified.Owing to the steady quality of 12V power consumption equipment own, price is low, so the utility model can bring considerable economic again.
Accompanying drawing is the utility model circuit theory diagrams.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, GB1, GB2 are two 12V storage batterys, and K is a change over switch, adopt key switch, comprise room end 1, working end 2 and start end 3, and K switch is being stirred to start end 3 by working end 2, and finishes after the startup, can automatically return to working end 2.Relay J 1 is a starter motor relay in original car, and conllinear circle J1 is connected in parallel on the start end 3 of K switch.Described in the figure, relay J 2, J3 and J4 are the performer of finishing the power supply conversion in the present embodiment, and wherein, the J2 coils from parallel connection of coils is in the start end 3 of K switch; J3 coil and the working end 2 that is connected in parallel on K switch after the J2 coil is connected; J4 coil and the working end 2 that is connected in parallel on K switch after normally opened contact J3 connects.The anodal termination starter of storage battery GB1 M, negative pole end one tunnel is often opened contact J4-1 ground connection, and the positive terminal that contact J2 meets storage battery GB2 is often opened on another road.The positive pole one tunnel of storage battery GB2 is often opened contact J4-2 and is met starter M, and another road meets the center-side O of K switch; Storage battery GB2 negative pole end ground connection.
Relay J 3 in the present embodiment adopts time-delay relay.
Pull out to start end 3 when K switch, relay J 1, J2 coil get electric, its contacting; Relay J 3, J4 and J5 are because coil losing electricity, its contact disconnects, this moment, the negative pole end of storage battery GB1 was connected by closed contact J2 and storage battery GB2 positive terminal, two storage battery GB1, GB2 provide 24V DC power supply in the mode of connecting to starter M, simultaneously, because contact J5 disconnects, other power consumption equipment power supply is open circuit.After finishing startup, K switch automatically returns to working end 2 by start end 3, at this moment, J3, J4 and J5 get, J1 and J2 dead electricity, the negative pole end of storage battery GB1 are by closing contact J4-1 ground connection, and the positive terminal of storage battery GB2 is connected with the positive terminal of storage battery GB1 by closing contact J4-2 simultaneously, GB1 and GB2 transfer with parallel connection output, and provide 12V power supply by closing contact J5 to other power consumption equipment.
