Be described in detail below in conjunction with the cooling system of accompanying drawing embodiment of the invention stable-pressure device and motor.
As shown in Figure 3, be a specific embodiment of stable-pressure device of the present invention.Said stable-pressure device comprises body 1; The side of said body 1 is provided with overflow hole 10, the bottom surface is provided with inlet opening 11, and said inlet opening 11 is connected with work box 16, and said work box 16 is connected with pressure transducer 7; Said pressure transducer 7 is electrically connected with controller 6 (ECU); Said controller 6 is electrically connected with coil 5, and the inside of said coil 5 is provided with iron core 4, and an end of said iron core 4 is provided with armature 3 relatively; Said armature 3 is fixedly connected with motion bar 2, and said motion bar 2 passes the side of said body 1 and relative with said overflow hole 10 movably.
The stable-pressure device that the embodiment of the invention provides comprises body 1, and the side of said body 1 is provided with overflow hole 10, the bottom surface is provided with inlet opening 11; Said inlet opening 11 is connected with work box 16, and said work box 16 is connected with pressure transducer 7, and said pressure transducer 7 is electrically connected with controller 6 (ECU); Said controller 6 is electrically connected with coil 5, and the inside of said coil 5 is provided with iron core 4, and a side of said iron core 4 is provided with armature 3; Said armature 3 is fixedly connected with motion bar 2, and said motion bar 2 passes the side of said body 1 and relative with said overflow hole 10 movably, and its beneficial effect that brings is; Controller (ECU) comes testing case pressure inside through pressure transducer; When the force value that detects approached the air pressure of body interior, motion bar was blocked overflow hole, and overflow hole does not have the liquid process; When the force value that detects during greater than the air pressure of body interior; Controller (ECU) makes coil and iron core energising, at this moment between coil and the iron core electromagnetic action takes place, and makes iron core produce electromagnetic attraction; And armature moves and is held by iron core to iron core owing to the effect of electromagnetic force; Move with the motion bar edge direction opposite with overflow hole that iron core is fixedly connected and separate with overflow hole, this moment, liquid flowed out from overflow hole, and then accomplished pressure release; When the force value that detects during less than the air pressure of body interior; Controller (ECU) makes coil and iron core energising, at this moment between coil and the iron core electromagnetic action takes place, and makes iron core produce electromagnetic attraction; And armature moves and is held by iron core to iron core owing to the effect of electromagnetic force; Move with the motion bar edge direction opposite with overflow hole that iron core is fixedly connected and separate with overflow hole, this moment, liquid flowed into from overflow hole, and then accomplished ftercompction.Find out that from above-mentioned this stable-pressure device is through pressure transducer collection pressure signal; And the break-make of coming automatic control coil electric current by program preset in the controller (ECU); And then control armature is mobile; So just utilize the principle of electromagnetic relay to come moving of control motion bar automatically, not only can improve the governing speed of pressure, also improved pressure controlled precision in the cooling system simultaneously.
Like Fig. 4 or shown in Figure 7, be electrically connected with electromagnetic relay 8 between controller described in the embodiment of the invention 6 and the said coil 5.Electromagnetic relay 8 can utilize the break-make of low voltage, dry circuit to control indirectly HV, heavy current circuit like this; Therefore in circuit, play effects such as automatic adjusting, safety protection and change-over circuit, and then the stable-pressure device in the embodiment of the invention can be worked normally.
Simultaneously; The pressure signal that controller 6 (ECU) collects through pressure transducer 7 comes the break-make of control electromagnetic relay 8 automatically; Break-make that then can control coil 5 electric currents; And then control armature 3 and the motion bar 2 that is connected with armature 3 is mobile, so not only can further improve the governing speed of pressure, has also further improved pressure controlled precision in the cooling system.
Referring to Fig. 4, be arranged with Returnning spring 9 on the armature described in the embodiment of the invention 3.After finishing pressure release or ftercompction; Cooling system pressure inside and body 1 pressure inside are approaching each other; Controller 6 breaks off through the SC sigmal control electromagnetic relay 8 that pressure transducer 7 provides, and then coil 5 does not have electric current to pass through, and the electromagnetic attraction of iron core 4 disappears; Because the effect of Returnning spring 9, armature 3 and motion bar 2 can in time reset; In addition in the process of pressure release or ftercompction; The electromagnetic attraction that iron core 4 is produced overcomes the active force of Returnning spring 9; Armature 3 is held, like this to armature 3 with play buffer function before iron core 4 contacts, avoided armature 3 to cause armature 3 or iron core 4 to be damaged with the collision of iron core 4.
It can also be seen that from Fig. 4 also be provided with seal ring 12 in the body described in the embodiment of the invention 1 with on the said overflow hole 10 opposed inside faces, said motion bar 2 passes said seal ring 12 movably.Can prevent like this that in stable-pressure device pressure release or ftercompction process liquid flow into the outside of body 1 from body 1 inside.
Like Fig. 4 or shown in Figure 5; The outside of body described in the embodiment of the invention 1 also is connected with iron core fixed base 13, the said iron core 4 of said iron core fixed base 13 internal fixation, and this makes body 1 and iron core 4 form the structure of an integral body; And then make the compact structure of stable-pressure device, save arrangement space.
Can know by Fig. 4 or Fig. 5; One end of said iron core fixed base 13 is provided with armature bolt 14; And said iron core fixed base 13 is connected with said iron core 4 through said armature bolt 14, and after coil 5 energisings, iron core 4 attracts in the process of armature 3 like this; Armature bolt 14 also can also be attracted each other with iron core 4, and then just can make iron core 4 in the stable-pressure device working procedure, can also be in a stable status.
Can know by Fig. 4 or Fig. 5 once more; Be provided with in the said iron core fixed base 13 and regulate bolt 15; And said iron core fixed base 13 is connected with said body 1 through regulating bolt 15; And the distance between length change control iron core 4 that can be through regulating bolt 15 and the armature 3, and then control motion bar 2 distance of separating with overflow hole 10, thus also can controlling liquid flow out or the speed of entering from overflow hole 10.
As shown in Figure 7; A kind of cooling system of motor; Comprise the stable-pressure device that above-mentioned each item is described, said work box 16 can be radiator, and the spout of said radiator is connected with the inlet opening 11 of said body 1; The end face of said body 1 also is provided with through hole, and liquid flow in the radiator from the through hole injection of body 1 and from inlet opening 11 and cools off like this.
From Fig. 7, find out, be coated with radiator pressure cap 17 described in the embodiment of the invention on the through hole, can prevent that like this liquid splash is to outside when carrying out pressure release or ftercompction.
In addition, the overflow hole 10 of said body 1 is connected with circulating stock chamber 21, and in pressure leak process, liquid flow in the circulating stock chamber 21 through overflow hole 10 like this; In the ftercompction process, the liquid in the circulating stock chamber 21 flow into body 1 inside through overflow hole 10, and finally flow into radiator inside.
The above; Be merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; Can expect easily changing or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by said protection domain with claim.
