Abstract

The present invention relates to a motor cover including: a first cover formed at one side with a housing coupling unit that is coupled with a motor housing; a second cover coupled to the other side of the first cover; and alignment units formed at the first and second covers to prevent a twist between the two covers by aligning an assembly position when the first cover and the second covers are assembled, and a motor including the motor cover, whereby a twist can be prevented when the motor cover is assembled and a dimensional accuracy can be enhanced.

Claims

1. A motor cover, comprising:

a first cover formed at one side with a housing coupling unit that is coupled with a motor housing;

a second cover coupled to the other side of the first cover; and

alignment units formed at the first and second covers to prevent a twist between the two covers by aligning an assembly position when the first cover and the second covers are assembled.

2. The motor cover of claim 1, wherein the first cover is made of resin material and formed by injection molding.

3. The motor cover of claim 1, wherein the second cover is made of a metal material to reinforce strength of the cover.

4. The motor cover of claim 1, wherein an upper margin of the first cover is formed with a first staircase sill and a margin of the second cover is formed with a second staircase sill that is press-fitted into the first staircase sill.

5. The motor cover of claim 1, wherein an upper surface of the first cover is protrusively formed with a terminal housing for power connection and a lug unit, respectively, and the second cover is formed with a first accommodation groove for accommodating the terminal housing, and a second accommodation groove for accommodating the lug unit, respectively.

6. The motor cover of claim 1, wherein the position alignment unit includes at least one or more press-fitting grooves formed on the upper surface of the first cover, and at least one or more press-fitting lugs formed at a lower surface of the second cover that are press-fitted into the press-fitting grooves.

7. The motor cover of claim 1, wherein the position alignment unit includes at least one or more press-fitting lugs formed on the upper surface of the first cover, and at least one or more press-fitting grooves formed at a lower surface of the second cover that are press-fitted by the press-fitting lugs.

8. A motor, comprising:

a motor housing,

a stator secured inside the motor housing, a rotor arranged at an inner surface of the stator to rotate by interacting with the stator, and

a motor cover coupled to an opening of the motor housing,

wherein the motor cover comprising,

a first cover formed at a lower surface with a housing coupling unit coupled to the motor housing,

a second cover coupled to an upper surface of the first cover, and

position alignment units formed at the first and second covers to prevent a twist between the two covers by aligning an assembly position when the first cover and the second covers are assembled.

9. The motor of claim 8, wherein the first cover is made of resin material and formed by injection molding.

10. The motor of claim 8, wherein the second cover is made of a metal material to reinforce strength of the cover.

11. The motor of claim 8, wherein an upper margin of the first cover is formed with a first staircase sill and a margin of the second cover is formed with a second staircase sill that is press-fitted into the first staircase sill.

12. The motor of claim 8, wherein an upper surface of the first cover is protrusively formed with a terminal housing for power connection and a lug unit, respectively, and the second cover is formed with a first accommodation groove for accommodating the terminal housing, and a second accommodation groove for accommodating the lug unit, respectively.

13. The motor of claim 8, wherein the position alignment unit includes at least one or more press-fitting grooves formed on the upper surface of the first cover, and at least one or more press-fitting lugs formed at a lower surface of the second cover that are press-fitted into the press-fitting grooves.

14. The motor of claim 8, wherein the position alignment unit includes at least one or more press-fitting lugs formed on the upper surface of the first cover, and at least one or more press-fitting grooves formed at a lower surface of the second cover that are press-fitted by the press-fitting lugs.
