Background technology
Automobile air valve regulation valve includes guide rod assembly and electromagnetic induction assembly.Guide rod assembly includes guide rod, permanent magnet, is arranged on the lower cover below permanent magnet and is arranged on the upper cover above permanent magnet, and the upper end of guide rod is through lower cover, permanent magnet and upper cover, and is connected with lower cover and upper cover respectively.Electromagnetic induction assembly is positioned at the top of guide rod assembly, including solenoid and iron core.Electromagnetic induction assembly can apply a downward thrust to guide rod assembly when solenoid is energized.Automobile air valve regulation valve work time, guide rod assembly can move back and forth up and down, ceaselessly retracted mode and stretch out between state change.
The guide rod assembly of existing automobile air valve regulation valve is when retracting, and the end face of guide rod can directly impinge the bottom surface of iron core.Owing to the comprcssive strength of iron core material is generally the highest, after the shock under multiple high temp, the bottom surface of iron core is easy to cave in, and following both sides problem, once cave in, can be brought in the bottom surface of iron core:
1, the magnetic circuit gap (magnetic circuit gap is unstable) between iron core and permanent magnet is decreased, the retracted mode retentivity causing guide rod assembly is increased up excessive always, the possible fragmentation of permanent magnet, guide rod is caused to be difficult to absorption on iron core, guide rod assembly is the most unexpected to be stretched out, and causes electromotor operation troubles；
2, it is mounted in the cylinder of automobile engine due to automobile air valve regulation valve, the therefore internal organic oil of automobile air valve regulation valve.Under the working environment of full machine oil, once cave in the bottom surface of iron core, is readily formed vacuum between iron core bottom surface and guide rod assembly, causes the guide rod assembly when the solenoid of electromagnetic induction assembly is energized to stretch out, the disabler of automobile air valve regulation valve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automobile air valve that iron core bottom surface can be delayed to cave in regulate valve.
For solving above-mentioned technical problem, this utility model embodiment provides the automobile air valve regulation valve delaying iron core bottom surface to cave in, including guide rod assembly and electromagnetic induction assembly；Guide rod assembly includes guide rod, permanent magnet, is arranged on the lower cover below permanent magnet and is arranged on the upper cover above permanent magnet；The upper end of guide rod is through lower cover, permanent magnet and upper cover, and is connected with lower cover and upper cover respectively；Electromagnetic induction assembly is arranged on the top of guide rod assembly；Electromagnetic induction assembly includes solenoid, coil rack and iron core；Solenoid winding is on the outer peripheral face of coil rack；The bottom surface of coil rack is provided with groove, and iron core is arranged in groove；Electromagnetic induction assembly can apply a downward thrust when solenoid is energized to guide rod assembly；Wherein, automobile air valve regulation valve also includes steel ball, and steel ball is fixed on the bottom of iron core, and partly protrudes from the bottom surface of iron core；Steel ball is just to guide rod.
This utility model is at least up to one of following beneficial effect:
1, the mandrel bottom of the automobile air valve regulation valve of this utility model embodiment is fixed with the steel ball protruding from iron core bottom surface, not only can increase shock stress surface, and avoid the guide rod direct shock to iron core bottom surface, therefore iron core bottom surface can be effectively delayed to sink, guarantee that the magnetic circuit gap between iron core and permanent magnet enough and is stablized, so that the retracted mode retentivity of guide rod assembly is constant, and increase the endurance quality of automobile air valve regulation valve；
2, contacting between steel ball with guide rod contacts for some face, rather than plane-plane contact, thus can effectively prevent from being formed in machine oil environment between iron core bottom surface and guide rod assembly vacuum.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is made and further illustrating.
Fig. 1 shows the cross-sectional view of the automobile air valve regulation valve according to this utility model one embodiment, and wherein guide rod assembly is in retracted mode, and Fig. 2 is the close-up schematic view of Fig. 1.Shown in Fig. 1 and Fig. 2, regulate valve according to the automobile air valve of this utility model one embodiment and include valve casing 1, fairlead 2, guide rod assembly, electromagnetic induction assembly and steel ball 5.
Fairlead 2 is arranged at the lower end of valve casing 1, and is connected with valve casing 1, and fairlead 2 and valve casing 1 limit valve pocket 10 jointly.
Guide rod assembly includes guide rod 31, permanent magnet 32, is arranged on the lower cover 33 below permanent magnet 32 and is arranged on the upper cover 34 above permanent magnet 32.Guide rod 31 is axially displaceably arranged in fairlead 2, and the upper end of guide rod 31, permanent magnet 32, lower cover 33 and upper cover 34 are positioned at valve pocket 10.The upper end of guide rod 31 is through lower cover 33, permanent magnet 32 and upper cover 34, and is connected with lower cover 33 and upper cover 34 respectively.
In the present embodiment, guide rod assembly also includes that damping ring 35, the material of damping ring 35 preferably employ rubber.Damping ring 35 is set on the outer peripheral face of permanent magnet 32, and the upper end of damping ring 35 abuts the bottom surface of upper cover 34, and the lower end of damping ring 35 abuts the end face of lower cover 33, and damping ring 35 can play cushioning effect when guide rod assembly moves axially.The material of upper cover 34 and lower cover 33 preferably employs steel, and guide rod 31 is welded to connect by Laser Welding with upper cover 34 and lower cover 33 respectively.
Electromagnetic induction assembly is arranged on the top of guide rod assembly, and is positioned at valve pocket 10.Electromagnetic induction assembly includes solenoid 41, coil rack 42 and iron core 43.Solenoid 41 winding is on the outer peripheral face of coil rack 42.The bottom surface of coil rack 42 is provided with groove 423, and iron core 43 is arranged in groove 423.Electromagnetic induction assembly can apply a downward thrust when solenoid 41 is energized to guide rod assembly.
Steel ball 5 is fixed on the bottom of iron core 43, and partly protrudes from the bottom surface of iron core 43；Steel ball 5 is just to guide rod 31.So, when guide rod 31 is retracted, it can be avoided that the directly shock that guide rod 31 is to the bottom surface of iron core 43, therefore iron core bottom surface can be effectively delayed to sink, guarantee that the magnetic circuit gap between iron core 43 and permanent magnet 32 is sufficiently stable, so that the retracted mode retentivity of guide rod assembly is constant, and increase the endurance quality of automobile air valve regulation valve.Through test statistics, according to the automobile air valve of this utility model embodiment regulate valve ensure that high-temperature vibrating, be full of machine oil working environment under work 1,000,000 times without losing efficacy.Preferably, steel ball 5 is the bottom being fixed on iron core 43 by the way of pressing.
It addition, contacting between steel ball 5 and the guide rod 31 of the automobile air valve regulation valve of this utility model embodiment contacts for some face, rather than plane-plane contact, thus can effectively prevent from being formed in machine oil environment between iron core bottom surface and guide rod assembly vacuum.
