Drawings
FIG. 1 is a schematic view of the present invention.
FIG. 2 is an exploded view of the present invention.
Fig. 3 is a schematic view of a heat dissipation fan according to the present invention.
FIG. 4 is a schematic view of a side cover of the present invention.
Detailed Description
The utility model is described in further detail below with reference to specific embodiments and the attached drawing figures:
referring to fig. 1, a brushless motor for a treadmill includes a brushless motor main body 1, a heat dissipating blade 2 is disposed on an outer side of the brushless motor main body 1, and the heat dissipating blade 2 is positioned on the outer side of the brushless motor main body 1 by a positioning member 3.
Specifically, the brushless motor body 1 includes a side cover 4, the side cover 4 extends toward the outer side of the brushless motor body 1 to form an extension 41, and the heat dissipation blades 2 are disposed on the extension 41.
In this embodiment, the extension 41 is a hollow tubular member, and has a hole through which the shaft 11 of the brushless motor body 1 can pass, and the shape and size of the hole are adapted to the shape and size of the shaft 11, so as to limit the vertical position of the shaft 11 on the premise that the extension can rotate along the shaft 11.
Further, a bearing (not shown) may be disposed between the side cover 4 and the shaft 11, and in this embodiment, the side cover 4 has a groove (not shown) for mounting the bearing at the other side surface of the extension portion 41, and the bearing is limited by a shaft retaining ring.
Referring to fig. 2 and 4, the extending portion 41 includes a positioning groove 42, the positioning element 3 is mounted on the positioning groove 42 and positions the heat dissipating blade 2 on the extending portion 41, and the positioning element 3 may be a shaft retaining ring.
In order to facilitate the matching between the heat dissipation blades 2 and the positioning member 3, the inner wall of the heat dissipation blade 2 extends toward the center thereof with a flange 21, and the positioning member 3 is matched with the flange 21 to position the heat dissipation blade 2.
In the brushless motor of this embodiment, the central shaft 11 is not rotated, and can be fixedly installed on the treadmill shell, and the shell rotates, for example, the side cover 4 rotates, and the rotation of the side cover 4 drives the heat dissipation fan 2 to rotate, thereby achieving the purpose of heat dissipation of the heat dissipation fan 2 to the motor.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
