Description

Technical Field

[0001] The utility model relates to a motor, in particular to a motor bracket with a sensor mounting seat. Background Art

[0002] Some motors can accurately detect the rotation angle of the shaft by installing a Hall sensor inside, so as to accurately control the rotation speed or rotation angle of the motor's output end. The function is very powerful and therefore widely used. However, the existing motor sensors are simply fixed inside the motor. After being vibrated by the motor itself, they are easily displaced, making the detection inaccurate. Therefore, the connection stability of the Hall sensor is poor, which is not conducive to the operation of the entire motor. In addition, the motor bracket lacks a structure for positioning the Hall sensor, which makes it very troublesome to assemble. Utility Model Content

The positioning posts 624 are located between the two engaging hooks 623. The distance between the two engaging hooks 623 is greater than the distance between the two positioning posts 624. Specifically, a protrusion 625 is provided on the surface of the positioning seat 622 between the two engaging hooks 623 in a protruding manner. The number of the protrusions 625 is two, and the two positioning posts 624 are respectively arranged on the two protrusions 625 in a one-to-one correspondence. By providing the protrusion 625 , the engaging hook 623 and the positioning column 624 can be stably arranged on one side of the mounting ring 621 , thereby ensuring the stability of the structure. Meanwhile, the protrusion 625 can be used to carry the sensor 5 .

By engaging the elastic hook 626a with the connecting hole 612, the mounting seat 62 can be quickly connected to the bracket body 61, thereby improving the convenience of assembly. A connecting portion 627 is provided between the connecting foot 626 and the mounting ring 621, and the mounting ring 621, the positioning seat 622, the connecting portion 627 and the connecting foot 626 are an integrated structure.
