fig. 2 is a half sectional view of the structure of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-2, the solenoid of engine oil valve includes coil assembly 1, and coil assembly 1 is last to be provided with casing 2, its characterized in that: the middle part of casing 2 is equipped with electromagnetic core mounting hole seat 3 of undercut setting, and the structure and the function of preceding yoke bush 6, back yoke bush 7 are realized to half section down in the first realization of mounting hole seat 3. The lower end of the mounting hole seat 3 is arranged in a closed mode, the hole wall of the mounting hole seat and the shell are integrally formed, and the front yoke bush 6 and the rear yoke bush 7 are separated through a middle thin shell transition portion 8. An inner cover 4 is arranged at the bottom side of the mounting hole seat and is positioned between the mounting hole seat and the electromagnetic iron core 5.

In the prior art, the shell is of a split structure, wherein the mounting hole seat comprises an upper half section front yoke bush and a lower half section rear yoke bush, the structure is complex to assemble, and meanwhile, the two parts are bound to have connecting seams, so that the inner cover of the shell is required to be arranged at a height similar to that of the mounting hole seat, and the production cost is increased.

The height of the inner cover 4 is less than half of the height of the mounting hole seat 3.

The inner cover 4 comprises a circular bottom surface and a tubular side surface, and the ring width of the circular bottom surface is smaller than the height of the tubular side surface.

The inner cover 4 is connected with the electromagnetic iron core 5 in a riveting manner.

The functional areas of the front yoke bush and the rear yoke bush of the integrally formed structure of the shell are machined and formed at one time, so that good cylindricity can be guaranteed, adverse effects of machining errors and increase of sliding friction of the iron core assembly are reduced, and the response performance of the electromagnet is improved. Meanwhile, the shell is of an integrally formed structure, so that the coil assembly and the iron core of the electromagnet can be completely isolated, and the risk that engine oil at the iron core part of the electromagnet in the existing structure leaks outwards from the coil assembly in the working process is avoided.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
