Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a waterproof motor housing. Background Art

[0002] During the production process of the motor, the stator and rotor are usually installed on the shell surface and sealed by snapping the end covers. However, when used outdoors or in a high-humidity environment, the traditional simple snapping is difficult to ensure the sealing of the connection. In order to improve the waterproof performance of the motor, common motor waterproofing methods at least include applying sealant to the connection in the form of glue. However, since the motor will vibrate when in use, long-term vibration will cause the sealant to separate from the shell, resulting in a decrease in waterproof performance. Summary of the invention

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a waterproof motor housing.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: a waterproof motor housing, comprising an upper housing and a lower housing, the upper housing and the lower housing are provided with flanges on the shell rims, the flanges are perpendicular to the housings, a lower embedding groove is provided on the flange of the lower housing, the inner groove surface in the lower embedding groove is a vertical surface, the outer groove surface of the lower embedding groove is an inclined surface, a matching groove is provided on the flange surface corresponding to the lower embedding groove, an embedded block matching with the lower embedding groove is provided on the flange of the upper housing, the embedded block and the upper housing are an integral structure, the embedded block is a right-angled trapezoidal structure, the inner ring surface of the embedded block is tightly matched with the vertical surface in the lower embedding groove, the outer inclined surface of the embedded block is parallel to the inclined surface of the lower embedding groove, and there is a gap between the two, a boss matching with the matching groove is provided on the flange of the upper housing, the boss is tightly buckled and connected with the matching groove, and the bottom of the lower embedding groove is filled with adhesive, and a plurality of glue embedding grooves are equidistantly provided on the inclined surface of the outer side of the embedded block and the inclined surface of the outer side of the lower embedding groove.

[0005] Preferably, a sealant is provided at the bottom of the lower embedding groove.

[0006] Preferably, the height of the boss is half the depth of the matching groove.

[0007] Preferably, the width of the cavity between the boss and the matching groove is equal to the gap between the embedding block and the lower embedding groove.

[0008] The utility model has the beneficial effects of arranging mutually matching lower embedding grooves and embedding blocks on the upper shell and the lower shell, and arranging glue embedding grooves on the surfaces of the two, and simultaneously arranging mutually matching matching grooves and bosses on the upper shell and the lower shell, the sealant enters the gap between the two and between the matching grooves and the bosses through the extrusion of the embedding blocks, and is squeezed into the glue embedding grooves at the same time, and the sealant in the glue embedding grooves can effectively prevent the upper shell and the lower shell from being disengaged during vibration, thereby avoiding the reduction of the waterproof performance of the motor.

[0012] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0013] Embodiment: A waterproof motor housing, such as Figure 1-Figure 2 As shown, it includes an upper shell 1 and a lower shell 2, and the upper shell 1 and the lower shell 2 are both provided with flanges 3 on their shell rims, and the flanges 3 are perpendicular to the shells. A lower embedding groove 4 is provided on the flange 3 of the lower shell 2, and the inner groove surface of the lower embedding groove 4 is a vertical surface, and the outer groove surface of the lower embedding groove 4 is an inclined surface. The surface of the flange 3 corresponding to the lower embedding groove 4 is provided with a matching groove 5, and an embedded block 6 that cooperates with the lower embedding groove 4 is provided on the flange 3 of the upper shell 1, and the embedded block 6 and the upper shell 1 are an integral structure. The embedded block 6 is of a right-angled trapezoidal structure, the inner ring surface of the embedded block 6 is tightly matched with the vertical surface in the lower embedded groove 4, the outer inclined surface of the embedded block 6 is parallel to the inclined surface of the lower embedded groove 4, and there is a gap 7 between the two, and a boss 8 is provided on the flange 3 of the upper shell 1 to cooperate with the matching groove 5, and the boss 8 is tightly buckled and connected with the matching groove 5, and the bottom of the lower embedded groove 4 is filled with adhesive. A plurality of glue embedding grooves 9 are equidistantly provided on the inclined surface of the outer side of the embedded block 6 and the inclined surface of the outer side of the lower embedded groove 4.

[0014] The bottom of the lower embedding groove 4 is provided with a sealant 10 ; the height of the boss 8 is half the depth of the matching groove 5 ; the width of the cavity between the boss 8 and the matching groove 5 is equal to the gap 7 between the embedding block 6 and the lower embedding groove 4 .

[0015] The principle of the utility model: before installation, it is necessary to pre-fill the sealant 10 at the bottom of the lower embedding groove 4, press the upper shell 1 onto the lower shell 2 through the die-casting machine, squeeze the embedding block 6 into the lower embedding groove 4, squeeze the sealant 10, and the sealant 10 will overflow into the gap 7 between the two and flow into the embedding groove 9 of the two. The remaining sealant 10 will flow into the gap 7 between the matching groove 5 and the boss 8 to achieve sealing. After the sealant 10 solidifies, the sealant 10 in the embedding groove 9 will pull the upper shell 1 and the lower shell 2 to prevent loosening due to vibration. The leather material connection is not tight enough.
