[0016] 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.

[0017] Please see Figures 1 to 4This utility model provides a waterproof motor, including an integrated housing 1. The inner wall of the integrated housing 1 is provided with a stator 2, the middle of the stator 2 is provided with a rotor 3, the middle of the rotor 3 is provided with a drive assembly 4, the rear of the integrated housing 1 is provided with an end cover 5, both sides of the end cover 5 are provided with annular protrusions 6, and both sides of the annular protrusions 6 are fitted with sealing rings 7. A sealing cover 8 is provided on the outer side of the end cover 5. Compared with the traditional design, the integrated housing 1 design, with the front cover 5, housing and rear cover 5, reduces the connection between parts, which is conducive to the assembly of the motor in the production process, improves its production efficiency, and improves its waterproof performance after production. At the same time, by providing sealing rings 7 on both sides of the end cover 5 and providing oil seals 412 at the connection between the drive shaft 41 and the integrated housing 1, the sealing of the connection of the outer parts is further improved, so that the motor meets the waterproof effect of special use scenarios and improves its practicality.

[0018] like Figure 3 As shown, specifically, the integrated housing 1 has fixing holes 101 at the four corners of its bottom, a snap-fit ​​groove 102 at the center of its bottom, an annular boss 103 on the inner bottom wall, a positioning platform 104 for mounting and positioning the stator 2 on the inner wall, and a wire-passing port 105 on the side wall of the integrated housing 1. A connector 106 is provided outside the wire-passing port 105. The positioning platform 104 facilitates the convenient hot-fitting of the stator 2 into the integrated housing 1 during production, improving production speed. By connecting the guide inside the integrated housing 1 through the wire-passing port 105 to the connector 106, the connector 106 is electrically connected to the external circuit, controlling the normal operation of the equipment.

[0019] Specifically, the fixing hole 101 facilitates the installation and fixing of this equipment. By fitting the oil seal 412 onto the outer circular wall of the drive shaft 41 and placing it within the snap-fit ​​groove 102, the structure becomes more compact and its aesthetics are improved.

[0020] Specifically, an annular boss 51 is provided on one side of the inside of the end cover 5. An annular boss 103 and an annular boss 51 are both provided with mounting grooves 9 in the middle. By installing the bearing 42 into the mounting grooves 9 in the middle of the annular boss 103 and annular boss 51 respectively, it is easy to achieve axial positioning of the drive shaft 41 and improve the stability of the motor drive.

[0021] like Figure 2 and Figure 4As shown, specifically, the drive assembly 4 includes a drive shaft 41 thermally mounted in the middle of the rotor 3, and bearings 42 for axial positioning of the drive shaft 41 are provided in the mounting grooves 9 on both sides. A keyway 43 is provided on the outward side of the drive shaft 41, and a connecting key 44 is installed in the keyway 43. The drive shaft 41 is connected to an external transmission device through the connecting key 44, thereby realizing the drive of the external transmission device.

[0022] Specifically, the outer circular wall of the drive shaft 41 is provided with a positioning platform 411 for mounting and positioning the rotor 3. An oil seal 412 is sleeved at the connection between the outer circular wall of the drive shaft 41 and the integrated housing 1. By setting the positioning platform 411, it is easy to quickly heat mount the rotor 3 to the corresponding position on the outer circular wall of the drive shaft 41. At the same time, the heat mounting method simplifies the internal structure and improves the efficiency of motor production and assembly and the stability during operation compared with the traditional key connection method.

[0023] Specifically, both the end cap 5 and the sealing cover 8 are cross-shaped, and the end cap 5 and the sealing cover 8 are provided with mounting holes 10 in a crisscross pattern. The side wall of the sealing cover 8 is provided with a wiring port 11, and a wiring terminal 12 is connected to the outside of the wiring port 11. The mounting holes 10 in a crisscross pattern on the end cap 5 and the sealing cover 8 facilitate the improvement of the aesthetics and overall consistency of the connection of external parts. Furthermore, by making the annular protrusions 6 on both sides of the end cap 5 fit against the inner wall of the integrated housing 1 and the sealing cover 8 respectively, and by using the sealing ring 7 to further improve the sealing performance of the connection, the overall waterproof effect and practicality of the equipment are improved.

[0024] The working principle of this utility model is as follows: When in use, the device is electrically connected to the external circuit through the connector 106 and the terminal 12. Then, through the external control system, the rotor 3 drives the drive shaft 41 to rotate in the middle of the stator 2, thereby driving the external transmission mechanism.
