Below, with reference to accompanying drawing, embodiments of the present invention are elaborated.
Fig. 1 represents the structure of positive and reverse rotation control circuit 1 of the motor of one embodiment of the present invention.Motor here is used for getting on or off the bus of automobile unblanked or locked with the switching body of door etc., and the control circuit 1 of Fig. 1 is installed in the automobile and controls the rotating of motor, get on or off the bus thus with etc. locking/unblank.
Control circuit 1 comprises that totally 6 open and close body switching motor 31～36.Above-mentioned switching body open and close with motor 31～36 respectively with driver's seat with a door DR, codriver's seat with AS, a rear portion left-hand door RL, the right side, rear portion RR, tail-gate TG, oil-feed flap FUEL respectively to open and close body corresponding and be provided with, just change/reverse and the switching body of correspondence locked unblank by motor.Rotating and reverse according to the sense of current that flows through motor of motor is switched.
6 open and close the body switching with opening and closing the body switching in the motor with motor 31～33 formation the 1st motor unit 30-1, are connected with a terminal (with the power supply opposition side) of a terminal of the 2nd fuse 21 (with the power supply opposition side) and the 2nd fuse 23 according to the mode of each motor parallel connection.Same in addition, open and close body and open and close with motor 34～36 formation the 2nd motor unit 30-2, be connected with a terminal (with the power supply opposition side) of a terminal of the 2nd fuse 22 (with the power supply opposition side) and the 2nd fuse 24 according to the mode of each motor parallel connection.
Above-mentioned the 2nd fuse 21 and another terminal (mains side) of 22 are connected with the terminal C of the switch 41b that the 1st repeat circuit 41 is possessed, in addition, the terminal C of the switch 42b that possessed of the 2nd fuse 23 and another terminal (mains side) of 24 and the 2nd repeat circuit 42 is connected.The the 1st and the 2nd repeat circuit 41,42 is used to switch the sense of current that flows through switching body switching usefulness motor 31～36, the terminal A of above-mentioned switch 41b, the 42b that possesses respectively is situated between and is connected terminal B ground connection by the plus end+B of the 1st fuse 10 with power supply (battery).Each switch 41b and 42b can switch connection status between terminal AC and between terminal BC.
Connection between this terminal is switched by the energising Be Controlled to the coil 41a, the 42a that are possessed in each repeat circuit.The terminal of coil 41a and 42a (being situated between by the 1st fuse 10) is connected with the plus end+B of power supply, and another terminal is connected with control unit 50.By this control unit 50, control is to the energising of each coil 41a, 42a.
As above such, 6 open and close the body switching and are connected with the 2nd repeat circuit 42 with the 1st repeat circuit 41 by each motor unit (the 1st motor unit 30-1, the 2nd motor unit 30-2) with motor 31～36.Be that relative the 1st repeat circuit 41 of each motor unit and the 2nd repeat circuit 42 are arranged in parallel, under the situation that the connection status of switch 41b, the 42b of each repeat circuit is switched, flow through all switching bodies and open and close sense of current with motor 31～36 by public switching.
Below the action of control circuit 1 with said structure is described.
By control unit 50, according to the coil 41a of the 1st repeat circuit 41 be switched on power supply (+B), the relative power supply of coil 42a of the 2nd repeat circuit 42 (+B) cold mode is controlled.At this moment, owing to coil 41a is energized, thereby the switch 41b of the 1st repeat circuit 41 is in connected state between terminal AC.In addition, because coil 42a no power, thereby the switch 42b of the 2nd repeat circuit 42 is in connected state between terminal BC.Switch 41b, the 42b of Fig. 1 represents the state of this moment.
So each opens and closes the body switching and uses the 1st repeat circuit 41 sides of motor 31～36 to be connected with the plus end+B of power supply, and the 2nd repeat circuit 42 side joint ground.Thereby each opens and closes body and opens and closes with motor 31～36 energisings, and electric current flows with the direction of the arrow among Fig. 1.
On the other hand, in control by control unit 50, the coil 42a of the 2nd repeat circuit 42 is switched on power supply, the relative power supply of coil 41a of the 1st repeat circuit 41 is under cold situation, because the energising of coil 42a, the switch 42b of the 2nd repeat circuit 42 is in connected state between terminal AC, in addition, because coil 41a no power, the switch 41b of the 1st repeat circuit 41 is in connected state between terminal BC.
Thereby each opens and closes the body switching and uses the 2nd repeat circuit 42 sides of motor 31～36 to be connected with the plus end+B of power supply, and the 1st repeat circuit 41 side joint ground.And, opening and closing with motor 31～36 energisings by in this manner each being opened and closed body, electric current flows with the direction opposite with arrow among Fig. 1.
Thus, switch to flow through by the control of controller unit 50 and respectively open and close body and open and close rotating and reverse the locking of controlling corresponding respectively switching body (each DR, AS, RR, RL, tail-gate TG, oil-feed flap FUEL) and unblank towards, switching motor with the electric current of motor 31～36.
Secondly, in the circuit of Fig. 1 constitutes, each opens and closes body and opens and closes with motor 31～36 and each repeat circuit 41,42 and be connected by the 2nd fuse 21～24, thereby the size of the electric current that each motor unit 30-1 and 30-2 are supplied with is limited by above-mentioned the 2nd fuse 21～24.In addition, by 10 pairs of all switching bodies of the 1st fuse are opened and closed with motor 31～36 public settings, limit the size of all supplying electric currents.
At this, to open and close respectively that body opens and closes with motor 31～36 necessary drive currents be 5A (ampere) in order to drive.At this moment, three for the 1st motor unit 30-1 open and close body switching motor 31～33, flow through the electric current that amounts to 15A, therefore the 2nd fuse 21 and 23 that connects on the path to the 1st motor unit 30-1 uses current capacity to be the fuse more than the 15A.Equally, use current capacity to be the fuse more than the 15A to the 2nd fuse 22 and 24 that on the path of the 2nd motor unit 30-2, connects.At this, the 2nd all fuses 21～24 is used the fuse of its current capacity as 15A.In addition, flow through the electric current of whole 30A in this control circuit 1, therefore the 1st fuse 10 employing current capacities are the fuse of 30A.
And the body that respectively opens and closes of Fig. 1 opens and closes with the current capacity of the wiring of the plus end+B of motor 31～36, each the 2nd fuse 21～24, each repeat circuit the 41～42, the 1st fuse 10, the connection power supply current capacity corresponding to the 1st fuse 10 and the 2nd fuse 21～24 and is set.Specifically, owing to crossing the current capacity of maximum and the 1st the fuse (=electric current that 30A) equates, so the wiring of this path part is used and the corresponding fuse of current capacity more than the 30A from the plus end+B of power supply to the path flow of each the 2nd fuse 21～24.On the other hand, open and close to each from the 2nd fuse 21～24 body open and close the electric current maximum that flows through path with motor 31～36 be restricted to the 2nd fuse current capacity (=15A).Thus, the wiring of this path part is the wiring corresponding with the current capacity more than the 15A.
In addition, as mentioned above, by setting the current capacity of each fuse and wiring, even under the situation of the position short circuit (ground connection) of the some P in hypothesis makes Fig. 1 for some reason, wiring can or not make all switching bodies open and close the state that is in akinesia with motor 31～36 simultaneously owing to the caused super-high-current of short circuit damages yet yet.Promptly put P and be grounded, and when being connected between the terminal AC of switch 41b, power supply (+B) and short circuit between some P, but this moment is in the minimum moment that is fused for the 2nd fuse 21 of 15A of current capacity, current interruptions.The current capacity of wiring than the 2nd fuse downstream (with the power supply opposition side) is more than the 15A, and is therefore injury-free, and the current capacity than the wiring of the 2nd fuse upstream side (mains side) is more than the 30A in addition, and is therefore injury-free.In addition, the 1st fuse 10 does not fuse, the 2nd fuse 22 and 24 also unaffected, and therefore the switching body of the 2nd motor unit 30-2 opens and closes with motor 34～36 regular events.
In addition, similarly, can not have problems under the situation of the position short circuit (ground connection) of the some Q in Fig. 1 yet.Promptly put Q and be grounded, and when being connected between the terminal AC of switch 42b, power supply (+B) and short circuit between some Q, but this moment is in the minimum moment that is fused for the 2nd fuse 23 of 15A of current capacity, current interruptions.The current capacity of wiring than the 2nd fuse downstream (with the power supply opposition side) is more than the 15A, and is therefore injury-free, and the current capacity than the wiring of the 2nd fuse upstream side (mains side) is more than the 30A in addition, and is therefore injury-free.In addition, the 1st fuse 10 does not fuse, the 2nd fuse 22 and 24 also unaffected, and therefore the switching body of the 2nd motor unit 30-2 opens and closes with motor 34～36 regular events.
Thus, promptly open and close a side of the upstream that becomes current path when body opens and closes with just the changeing of motor and become when reversing among these both sides of a side of upstream of current path by both sides in motor unit, be provided with the 2nd fuse, even open and close the either side generation short circuit of using motor thereby open and close body, the 2nd fuse also opens and closes irrelevantly and play a role effectively with the just commentaries on classics/counter-rotating of motor with opening and closing body, prevents that damage or all switching body switchings of connecting up be failure to actuate simultaneously with motor.
At this, in the control circuit 1 of Fig. 1, the 1st fuse the 10, the 1st repeat circuit the 41, the 2nd repeat circuit 42 and the 2nd fuse 21～24 are incorporated in the fuse box of the front part that is arranged at automobile.On the other hand, each open and close body open and close with motor 31～36 need be configured in correspondence the switching body near, because each DR, AS, RR, RL or tail-gate TG, oil-feed flap FUEL are positioned at the postmedian of automobile, therefore be several meters to the cloth line length that each switching body opens and closes with motor 31～36 from the 2nd fuse 21～24.In the circuit of Fig. 1 constitutes, because the current capacity of the wiring of this part is little to about 15A, therefore compare with the situation of current capacity 30A, can make the variation in diameter of wiring.In addition, diameter is thin more, and the cost of wiring is cheap more.Therefore, owing to can make the variation in diameter of several meters long wiring, thus can reduce the cost of control circuit 1.
And then, in the control circuit 1 of Fig. 1, owing to be provided with the 2nd fuse 21～24, therefore can access the structure (also can not have problems as mentioned above) that each motor unit 30-1,30-2 are connected with public repeat circuit (the 1st repeat circuit 41 and the 2nd repeat circuit 42) even put the P short circuit in the downstream of repeat circuit (with the power supply opposition side).Relative therewith, only adopting upstream side (mains side) at repeat circuit to be provided with under the situation of structure of fuse, open and close with the motor akinesia that becomes simultaneously for fear of all switching body, need as above-mentioned Fig. 3, each motor unit and different repeat circuit connections.Promptly increase the number of repeat circuit.Thus, can make repeat circuit shared in control circuit 1, its number is minimum to get final product, and therefore can further reduce the cost of control circuit 1.
More than, with reference to accompanying drawing, one embodiment of the present invention at length is illustrated, but concrete structure is not limited to above-mentioned structure, in the scope that does not break away from main points of the present invention, can carry out various design alterations etc.
For example, opening and closing the body switching also can be several with the number of motor and the number of motor unit.
In addition, except opening and closing body, control opens and closes the control circuit of the rotating of using motor, if, then can obtain identical effect with the cost aspect for fail safe for the peephole of electric opening and closing peephole (door mirror) opens and closes circuit, adopts the headlight of the optical axis of electronic adjustment headlight to adjust motor circuit, adopts wiper drive circuit, all automatic windows of a plurality of motor to open and close circuit etc. simultaneously, a plurality of motor are carried out the circuit of rotating control simultaneously.
In addition, even only at one-sided the 2nd fuse that is provided with of each motor unit (for example for the 1st motor unit 30-1, the 2nd fuse 21 only is set and the 2nd fuse 23 is not set), also can make from fuse box similarly to attenuate, therefore also can obtain identical effect from the cost aspect to the cloth linear diameter that each switching body opens and closes with motor.
