There is a ceiling fan motor housing and housing cover laterally fixed structure (Taiwan Certificate No. I555312 Patent Case), which includes a motor housing and a housing cover. The motor housing has a top side and a side wall. The side wall portion has a plurality of side-piercing guide holes, the cover body has a cover body portion and a top side ring flange portion, and the side of the top side ring flange portion is provided with a plurality of screw-shaped fixing holes. The flange of the top side ring is additionally provided with a plurality of blade fixing holes for fixing the blade bracket. By using a plurality of bolts to penetrate through the side guide holes and screw to the fixing holes, the motor housing and the housing cover can be locked.

Although the above structure can be used to laterally fix the ceiling fan motor housing and the housing cover, it has the following shortcomings:

1. Because the side-piercing guide holes of the motor housing are arranged at intervals around the circumferential direction of the side wall portion, that is, the side-piercing guide holes are not arranged on the same plane, which not only has many processing steps and time Long and easy to cause machining errors.

2. Since the fixing holes of the cover body are arranged at intervals around the circumferential direction of the flange portion of the top side ring, the fixing holes must be tapped again after the fixing holes are drilled in stages. Processing not only has many processing procedures and long processing time, but also easily causes processing errors.

3. The positions of the side-piercing guide holes of the motor housing and the fixing holes of the top side ring flange portion of the housing cover body are likely to be unable to be completely aligned due to machining errors, and assembly is difficult.

The peripheral wall 21 has an inner side surface 211 opposite to the annular surface 13 and for fixing the rotor 102, an outer side surface 212 opposite to the inner side surface 211, and an outer side surface 212 corresponding to the housing member 10 and opposite to the top wall 22 The bottom end 213, and most of the cut grooves 214. The bottom end portion 213 has a bottom end surface 215 connected between the inner side surface 211 and the outer side surface 212. The cut grooves 214 are recessed from the bottom end surface 215 toward the top wall 22 and communicate with the inner side surface 211 and the top wall 22. Outside 212. The top wall 22 has an upper shaft hole 221 for the shaft 104 to pass through and another bearing 105 to sleeve. The positioning members 23 are arranged at equal intervals around the axis L, and each has a connecting end 231 connected to the bottom end 213, and a positioning end 232 opposite to the connecting end 231 and opposite to the bottom surface 11. , And a through hole 233 disposed at the positioning end 232 and corresponding to the screw holes 14 respectively. Each pair of cut grooves 214 are separately provided on both sides of the connecting ends 231 of the positioning members 23. The connecting ends 231 of the positioning pieces 23 are respectively nested in the grooves 15. The positioning pieces 23 can be bent into an L-shape (as shown in the solid line in FIG. 1 and the imaginary line in FIG. 3). 1 imaginary line, and solid lines in Figures 2 and 3), when the positioning elements 23 are straight, the connecting end 231 of each positioning element 23 is located on the side of the positioning end 232 along the straight axis X, and can be Drilling of the perforation 233 is performed at the positioning end 232.

The locking members 30 are screws. After the positioning members 23 are bent into an L shape, they are respectively penetrated through the perforations 233 and screwed in the screw holes 14.

In order to further understand the effects of the cooperation of the components of the present invention, the technical means used, and the expected effects, the following description is hereby explained. It is believed that a more in-depth and specific understanding of the present invention can be obtained from this.

As shown in FIG. 1, when the components of the ceiling fan motor outer cover 100 are completed and not yet assembled, the positioning members 23 extend along the straight axis X in a straight plate shape (as shown in the solid line in FIG. 1 and the imaginary line in FIG. 3). Line), at this time, the drilling of the perforations 233 can be performed at the positioning ends 232.

As shown in Figures 2 and 3, when the ceiling fan motor outer cover 100 is to be wrapped around the ceiling fan motor unit 1 and assembled, the operator first passes the shaft 104 of the stator 101 through the housing member 20, and make the stator body 103 correspond to the rotor 102 pre-fixed on the inner surface 211 of the housing 20, and then the bearings 105 are respectively sleeved on the shaft 104 and correspond to the The upper shaft hole 221 and the lower shaft hole 16 can enable the casing member 20 to rotate smoothly relative to the stator 101.

Then, when the housing member 10 is to be assembled with the housing member 20, the operator aligns the grooves 15 with the positioning members 23, and moves the housing member 10 toward the housing along the axis L The cover 20 is sleeved until the narrow-diameter section 132 is sleeved inside the housing 20 and the narrow-diameter section 132 is opposite to the inner side surface 211. Next, the positioning members 23 are bent into an L shape (as shown by the imaginary line in Fig. 1 and the dashed line in Fig. 2 and the solid line in Fig. 3) from a straight plate shape (solid line in Fig. 1 and imaginary line in Fig. 3), and The positioning ends 232 are pressed against the bottom surface 11 so that the perforations 233 are aligned with the screw holes 14 respectively. The operator can then use the locking members 30 to pass through the perforations 233 and screw them on In the screw holes 14, the housing member 10 can be locked to the housing member 20 and the ceiling fan motor outer cover 100 can be positioned relative to the ceiling fan motor unit 1.

Then, the effects of the present invention are summarized as follows:

1. Since the screw holes 14 are located on the bottom surface 11 of the same plane, the screw holes 14 can be processed at the same time. The processing steps of the screw holes 14 are simplified, the processing time is short, and processing errors can be avoided.

2. The shell cover 20 utilizes the arrangement of the cut grooves 214, so that when the positioning members 23 are bent into an L shape from a straight plate, the offset can be absorbed and the perforation 233 of each positioning member 23 It can accurately correspond to the screw holes 14, the drilling position of the perforations 233 does not need to be controlled to be absolutely precise, the processing of the perforations 233 is easy, and the screw locking operation of the locking members 30 is also quite easy. The assembly of 10 and the housing 20 is quite easy.

3. When the housing base 10 is used to provide the recesses 15 and the housing base 10 is to be assembled with the housing cover 20, the recesses 15 are used to provide the positioning members 23 for embedding, so that the The assembly of the housing member 10 and the housing member 20 is quite easy.

In summary, the ceiling fan motor outer cover of the present invention has a simple overall structure, easy manufacturing and assembly, can reduce production costs, and can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
