Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Referring to fig. 1-2, a cover fixing structure provided for an embodiment of the present invention includes a motor 2, a cover 3, a clamping structure 31, and a fixing member, wherein the clamping structure 31 clamps the cover and the motor, and the fixing member is used for fixing the motor and the cover. When the motor fixing device is installed, the cover cap and the motor are clamped by the clamping structure, then the fixing piece is installed, the motor does not need to be manually abutted against the cover cap, the fixing piece can be directly installed, and the installation of an operator is facilitated.
The fixing piece is a screw, four screws are adopted for complete fixation through the structure, and after the clamping structure is arranged, at most three screws are needed, at least one screw is needed, two screws are preferably selected, the two screws are high in stability, the two screws are saved, the cost is reduced, and the processing cost is also reduced. The motor 2 is arranged in a housing 1, the housing 1 is provided with a cavity, and the housing covers the motor in the housing.
As shown in fig. 3 and 6, the clamping structure 31 is at least one buckle integrally formed with the cover, the buckle includes a first connecting portion 311 and a second connecting portion 312, an end of the first connecting portion 311 is fixed on the inner surface of the cover 3, the second connecting portion 312 is connected with the first connecting portion 311, and an included angle between the first connecting portion and the second connecting portion is 60 ° to 120 °, preferably 90 °. The same number of clip portions 21 as the number of the clips are provided on the motor 2, and the clips fasten the clip portions 21 to the cover, that is, the inner surface of the second connecting portion 312 of the clips fasten the clip portions 21 to the cover 3.
A cavity 22 is provided at a position where the motor 2 faces the clamping plate portion 21, a through hole 211 through which the clip passes is provided on the clamping plate portion 21, both the first connecting portion 311 and the second connecting portion 312 of the clip pass through the through hole 211, and the cavity 22 is a space for providing rotation of the second connecting portion.
In some preferred embodiments, for better installation, a gap is provided between the inner surface of the second connecting portion 312 and the inner surface of the clamping plate portion 21, a slant plate portion 313 (fig. 4) is provided at the connecting position of the first connecting portion and the second connecting portion of the buckle, the slant plate portion 313 is provided with a slant, and the slant plate portion 313 clamps the cover 3 and the clamping plate portion 21 when the cover 3 is clamped with the motor 2, so that only a small portion of the slant plate portion contacts with the cover, and heat transfer between the motor and the cover is reduced. When the motor cover is installed, the buckle is inserted into the through hole 211, the cover cap 3 is rotated, the buckle is driven to rotate together, the cover cap 3 and the motor 2 are clamped, during clamping, the mounting hole in the cover cap 3 is aligned with the mounting hole in the motor, and then the two screws are installed. Compared with the prior universal technical scheme of directly using four screws, the clamping buckle not only can clamp the motor and the cover cap tightly, but also can play a role in positioning, two screws are also reduced, the raw material cost is reduced, and the production cost is also reduced.
