[0002] A plastic-encapsulated motor is a micro-motor that uses plastic encapsulation technology to completely encapsulate the core components of the motor, such as the stator core and windings, with engineering plastics. Compared with traditional metal-cased motors, plastic-encapsulated motors have significant advantages in structure, performance, and application, and are widely used in household appliances, industrial equipment, automobiles, and other fields.

[0003] Chinese Patent No. CN221009894U discloses a molded motor, including a molded motor body. Two lugs are provided at the upper and lower ends of the outer walls on both sides of the molded motor body, and the two lugs are positioned correspondingly. A threaded hole is provided at the center of each lug. An adjusting screw is installed in the threaded hole of the two corresponding lugs. A lead wire outlet is provided at the lower end of the front side wall of the molded motor body. A fixed mounting plate is provided below the molded motor body, and the lower ends of four adjusting screws are connected to the fixed mounting plate. A lead wire limiting plate is provided below the lead wire outlet and connected to the bottom of the molded motor body.

[0004] The above technical solution has the following drawbacks: The encapsulated motor needs to be connected to a lead wire limiting plate at its bottom to fix the power lead wires of the encapsulated motor body and prevent the power lead wires from becoming messy. However, the production and manufacturing of the lead wire limiting plate will incur corresponding costs, and the transportation of the lead wire limiting plate will further increase the cost. In addition, the installation of the lead wire limiting plate will increase the number of processes and assembly time, and increase labor costs. Utility Model Content

[0008] In the aforementioned novel encapsulated motor, the encapsulated stator has a groove, and the cover plate has a protrusion that is inserted into the groove.

[0009] In the aforementioned novel encapsulated motor, the receiving groove is provided with a positioning step that is adapted to the cover plate.

[0010] In the aforementioned novel encapsulated motor, a wire protection clip is provided inside the receiving groove.

[0011] In the aforementioned novel encapsulated motor, a guide pin is provided in the receiving groove.

[0012] In the aforementioned novel encapsulated motor, the encapsulated stator is provided with at least two mounting feet, and each of the two mounting feet has an oblong hole.

[0013] In the aforementioned novel encapsulated motor, one side wall of the mounting foot is recessed inward to form an arched structure.

[0014] In the above-mentioned novel encapsulated motor, several limiting grooves are distributed on the lower surface of the protrusion, and several limiting grooves are distributed at the bottom of the groove.

[0015] In summary, the beneficial effects of this utility model compared to the prior art are as follows:

[0016] A receiving groove is opened at the bottom of the plastic-encapsulated stator, and the circuit board is placed in the receiving groove. The opening of the receiving groove is sealed by a cover plate, which protects the circuit board, reduces the influence of the external environment, and ensures the stable operation of the circuit board. This improves the stability and reliability of the plastic-encapsulated motor.

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] A new type of encapsulated motor, such as Figures 1 to 5 As shown, the device includes a plastic-encapsulated stator 1, a rotor 2, and a circuit board 3. The rotor 2 is rotatably mounted on the plastic-encapsulated stator 1. A receiving groove 4 is provided at the bottom of the plastic-encapsulated stator 1, and the circuit board 3 is placed in the receiving groove 4. The circuit board 3 is adapted to the receiving groove 4, which can effectively improve the stability of the circuit board 3.

[0025] The encapsulated stator 1 is provided with a cover plate 5, which is used to cover the opening of the receiving groove 4. It should be noted that by covering the opening of the receiving groove 4 with the cover plate 5, the receiving groove 4 is sealed, thereby protecting the circuit board 3 inside the receiving groove 4, reducing the impact of the external environment on the circuit board 3, ensuring the stable operation of the circuit board 3, and thus improving the stability and reliability of the encapsulated motor.

[0026] The cover plate 5 and the plastic-encapsulated stator 1 are fitted together to form several limiting holes 6 for limiting the power leads. Specifically, the cover plate 5 has several limiting grooves 7 and the plastic-encapsulated stator 1 has several limiting grooves 8. The several limiting grooves 7 and the several limiting grooves 8 are combined to form several limiting holes 6. The several limiting grooves 7 and the several limiting grooves 8 are all arc-shaped to fit the shape of the power leads.

[0027] In the prior art, the power leads of the encapsulated motor body are fixed by setting a lead wire limiting plate to prevent the power leads from becoming messy. In this embodiment, the power leads are directly fixed by the limiting hole 6 formed by the combination of limiting groove 1 7 and limiting groove 2 8, thus avoiding the power leads becoming messy. The lead wire limiting plate is eliminated, which effectively reduces the production cost and eliminates the installation process of the lead wire limiting plate, thereby improving the assembly efficiency.

[0028] The encapsulated stator 1 has a groove 9, and the cover plate 5 has a protrusion 10. The protrusion 10 is inserted into the groove 9. The groove 9 limits the protrusion 10, thereby limiting the cover plate 5. This ensures the relative stability of the cover plate 5 and the encapsulated stator 1. Furthermore, several limiting grooves 1 7 are distributed on the lower surface of the protrusion 10, and several limiting grooves 2 8 are distributed at the bottom of the groove 9. During assembly, the protrusion 10 is simply inserted into the groove 9 to complete the assembly of the cover plate 5 and the encapsulated stator 1. This ensures that several limiting grooves 1 7 and several limiting grooves 2 8 are combined to form several limiting holes 6, making the assembly more convenient and faster, and effectively improving the assembly efficiency.

[0029] The receiving groove 4 is provided with a positioning step 11 that is adapted to the cover plate 5. The stability of the cover plate 5 can be effectively improved by the positioning step 11 restricting the cover plate 5.

[0030] The receiving groove 4 is equipped with a wire exit protection clip 12, which fixes the wire exit end of the stator coil to prevent damage to the wire exit end of the stator coil during the injection molding process. It also makes the connection between the stator coil and the circuit board 3 more stable, thereby improving the stability and reliability of the encapsulated motor.

[0031] A pin 13 is provided in the receiving groove 4. The pin 13 is welded to the output end of the stator coil to form a stable connection. The pin 13 can be used as a connecting component between the stator coil and the circuit board 3.

[0032] The encapsulated stator 1 is provided with at least two mounting feet 14, which are arranged opposite to each other to ensure the stability and balance of the encapsulated motor.

[0033] Both mounting feet 14 are provided with oblong holes 15. Due to the function of the oblong holes 15, the position of the encapsulated motor can be adjusted along the length of the oblong holes 15 during installation to accommodate installation errors, thereby improving installation efficiency and accuracy.

[0034] The side wall of the mounting foot 14 is recessed inward to form an arched structure 16. The arched structure 16 can effectively enhance the support force of the waist-shaped hole 15. The arched structure 16 can effectively disperse stress and reduce stress concentration at the edge of the waist-shaped hole 15, thereby improving the load-bearing capacity and service life of the mounting foot 14.

[0035] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
