Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor housing. Background Technology

[0002] An electric motor typically consists of a housing, inside which the stator and rotor are housed. The motor housing primarily serves to waterproof, dustproof, and isolate the internal components, preventing dust and moisture from entering and damaging them. This ensures long-term stable operation of the motor and extends its service life.

[0003] Currently, existing motor housings typically consist of an upper housing and a lower housing. The upper housing has an upper flange, and the lower housing has a lower flange. Both the upper and lower flanges have several through holes. When assembling the motor housing, the upper and lower flanges can be fitted together to align and connect the through holes, and then rivets can be passed through for fixation. However, since the upper and lower housings are not pre-fixed before being connected by rivets, they are prone to displacement when subjected to external forces, causing the through holes to shift and no longer align and connect. If the through holes are not fully aligned and the rivets are forcibly passed through and tightened, the through holes are easily damaged, making the rivet connection unstable and affecting the connection strength of the motor housing. Utility Model Content

[0004] The purpose of this utility model is to provide a motor housing in order to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a motor housing, including an upper housing and a lower housing, wherein the upper housing is provided with an upper flange, and the lower housing is provided with a lower connecting shell for embedding the upper flange, wherein the upper flange is provided with a plurality of upper through holes, and the lower connecting shell is provided with a plurality of lower through holes, wherein a stop plate is provided on the lower connecting shell, and an abutment plate is provided on the upper flange for abutting against the stop plate, wherein when the abutment plate abuts against the stop plate, the upper through holes and the lower through holes are aligned and connected.

[0006] As a further feature of this invention, the abutting piece is provided with an insert block, and the stop piece is provided with a through groove for the insert block to pass through.

[0007] As a further feature of this invention, the upper flange and the lower connecting shell are detachably connected together by a connecting assembly.

[0008] As a further feature of this utility model, the connecting assembly includes several nuts fixed to the bottom of the lower connecting shell and several bolts that match the nuts, with the nuts corresponding to the lower through holes in sequence.

[0009] As a further feature of this invention, the bolt includes a nut with a groove, the nut being used to be embedded inside the lower connecting shell.

[0010] As a further feature of this invention, both the upper and lower shells are made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During assembly, the upper and lower housings of this invention can be closed, allowing the upper flange to be inserted into the lower connecting housing. Then, rotating the upper housing causes the upper flange to rotate, which in turn causes the abutment piece to move. When the abutment piece contacts the stop piece, the upper and lower through holes align and connect. By limiting the upper flange with the lower connecting housing and the abutment piece with the stop piece, the positions of the upper and lower through holes can be maintained, achieving pre-fixation before connection. This ensures that the upper and lower through holes align and connect, facilitating fixing and guaranteeing the secure connection of the motor housing. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3As shown, the motor housing includes an upper housing 1 and a lower housing 2. Both the upper housing 1 and the lower housing 2 are made of stainless steel, which has high strength and hardness, is not easily corroded, and has good durability. An upper flange 3 is provided on the upper housing 1, and a lower connecting shell 4 is provided on the lower housing 2 for the upper flange 3 to be inserted. Several upper through holes 5 are provided on the upper flange 3, and several lower through holes 6 are provided on the lower connecting shell 4. A stop plate 7 is provided on the lower connecting shell 4, and an abutment plate 8 is provided on the upper flange 3 for abutting against the stop plate 7. When the abutment plate 8 abuts against the stop plate 7, the upper through holes 5 and the lower through holes 6 are aligned and connected. Therefore, when assembling the motor housing, the upper housing 1 and the lower housing 2 can be closed, so that the upper flange 3 is inserted into the lower connecting shell 4. Then, the upper housing 1 is rotated, which drives the upper flange 3 to rotate. This allows the abutment piece 8 to move accordingly. When the abutment piece 8 abuts against the stop piece 7, the upper through hole 5 and the lower through hole 6 can be aligned and connected. By limiting the upper flange 3 with the lower connecting shell 4 and limiting the abutment piece 8 with the stop piece 7, the positions of the upper through hole 5 and the lower through hole 6 can be maintained, achieving pre-fixation before connection. This allows the upper through hole 5 and the lower through hole 6 to be aligned and connected, facilitating fixation and ensuring the connection firmness of the motor housing. An insert block 9 is provided on the abutment piece 8, and a through groove 10 for the insert block 9 to pass through is provided on the stop piece 7. When the abutment piece 8 abuts against the stop piece 7, the insert block 9 will pass through the through groove 10. By limiting the insert block 9 with the through groove 10, the connection firmness between the abutment piece 8 and the stop piece 7 can be improved, thereby improving the positioning stability of the upper through hole 5 and the lower through hole 6.

[0020] Please see Figure 1-4 As shown, the upper flange 3 and the lower connecting shell 4 are detachably connected together by a connecting assembly. The connecting assembly includes several nuts 11 fixed to the bottom of the lower connecting shell 4 and several bolts that match the nuts 11. The nuts 11 correspond to the lower through holes 6 in sequence. When it is necessary to assemble the motor housing, the upper flange 3 can be inserted into the lower connecting shell 4 first, so that the upper through holes 5 and the lower through holes 6 are aligned and connected. Then, the bolts are inserted through the upper through holes 5 and the lower through holes 6 in sequence, and then threaded together with the nuts 11. The connection is relatively firm and easy to disassemble. The bolt includes a nut 12 with a groove. The nut 12 is used to be inserted into the lower connecting shell 4. The bolt can be tightened by inserting a screwdriver into the groove and applying force. After the bolt is connected to the nut 11, the nut 12 will be hidden inside the connecting shell to avoid accidentally touching the bolt and causing the connection between the bolt and the nut 12 to loosen.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
