Abstract
The utility model relates to a convenient mounting structure of lid self tapping screw behind vehicle electronic water pump motor, lid behind motor, the lid passes through self tapping screw tightening's mode fixed connection behind machine and the motor, it has a plurality of bellying to mould plastics through injection moulding process on the motor, be equipped with the unthreaded hole on the bellying. The utility model adopts the unthreaded hole structure, so that the manual placing process is saved during injection molding, the cost is saved, and the stability is increased; secondly, the metal and the plastic do not react during injection molding, so that the injection molding stability is improved; and finally, the self-tapping screw is adopted, so that the motor and the rear cover of the motor are completely sealed, and the motor is fast to install and reliable and firm to install.
Description
Technical Field
The utility model relates to an electronic pump installation technical field specifically is a convenient mounting structure of lid self-tapping screw behind vehicle electronic pump motor.
Background
The mounting mode of the motor rear cover on the existing electronic water pump is generally that a threaded bushing is connected and mounted in a screw matching mode, and the mounting mode is convenient and fast and is convenient to disassemble, assemble and maintain. However, the existing threaded bushing is made of stainless steel, the plastic coating is engineering plastic, and injection molding deformation or threaded bushing bulge and flash are caused by expansion and contraction of heat during plastic coating, so that the motor and the rear cover of the motor cannot be completely sealed; on the other hand, the screw thread bushing is limited by the injection molding process, is manually placed, has a certain gap, and is influenced when the mold is closed, so that the screw thread bushing is raised or sunken, and further the injection molding process is defective.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a convenient mounting structure of lid self-tapping screw behind vehicle electronic water pump motor.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
the utility model provides a convenient mounting structure of lid self-tapping screw behind vehicle electronic water pump motor, lid behind motor, lid passes through the mode fixed connection that self-tapping screw screwed up behind machine and the motor.
Furthermore, a plurality of protruding parts are formed on the motor in an injection molding mode through an injection molding process.
Furthermore, the protruding part is provided with a light hole.
The utility model has the advantages that:
the utility model adopts the unthreaded hole structure, so that the manual placing process is saved during injection molding, the cost is saved, and the stability is increased; secondly, the metal and the plastic do not react during injection molding, so that the injection molding stability is improved; and finally, the self-tapping screw is adopted, so that the motor and the rear cover of the motor are completely sealed, and the motor is fast to install and reliable and firm to install.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is an exploded view of the structure of the present invention;
fig. 2 is a schematic view of the structure of the motor of the present invention.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained with the accompanying drawings and the embodiments.
As shown in fig. 1 to 2, the convenient mounting structure of the self-tapping screw of the rear cover of the motor of the electronic water pump for the vehicle comprises a motor 1 and a rear cover of the motor 2, wherein the motor 1 is provided with four protrusions 3 through injection molding, the end faces of the four protrusions 3 are provided with unthreaded holes 4, the rear cover of the motor 2 is of a metal structure, the outer end face of the rear cover of the motor is provided with four mounting holes corresponding to the four protrusions 3 one by one, and the self-tapping screws 5 for fixedly connecting the motor 1 and the rear cover of the motor 2 are mounted on the unthreaded holes 4 and the mounting holes. The structure is matched with the unthreaded hole 4 in a self-tapping mode through the self-tapping screw 5, so that the end face of the motor 1 is tightly attached to the end face of the motor rear cover 2, and the effect of complete sealing is achieved. Compared with the existing threaded bushing, the structure simplifies the structure of the injection mold, removes one process, reduces the production cost, increases the injection molding precision of parts, and reduces the injection molding risk of the parts.
When the motor rear cover is used, the end face between the motor 1 and the motor rear cover 2 is completely attached, the unthreaded hole 4 is aligned with the mounting hole, and the tapping screw 5 is screwed until the motor rear cover is screwed down.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
