Supporting and heat dissipating structure for motor having integrated driver

摘要

The present disclosure provides a supporting and heat dissipating structure. A driver is arranged on an inner surface of a heat sink. The heat sink has protrusions for heat dissipation. An axle hole and a fixing ring are formed at the center of the heat sink. An elastic ring is arranged around the fixing ring for connecting with a supporting frame. A tubular barrel is used for connecting the heat sink to a motor. A structure for easily and firmly supporting the motor and the driver can be obtained. The structure can also absorb vibration while the motor rotating.

1. A supporting and heat dissipating structure for a motor device having an integrated driver, the motor device including a motor and an output axle and a driver component for driving the motor to rotate, the supporting and heat dissipating structure comprising:
a connecting ring arranged at an end of the motor; a tubular barrel connected to the connecting ring and formed of a closed loop shape from a metal plate; a heat sink connected to the tubular barrel and having an inner surface for mounting the integrated driver, an outer surface formed with a plurality of protrusions, and an axle hole formed at the center thereof; a fixing ring extending from the outer surface and around the axle hole; an elastic ring fixed around the fixing ring; and a supporting frame for holding the elastic ring; wherein the heat sink is connected through the tubular barrel to the end of the motor so that the heat sink is opposite to and spaced from the motor by the tubular barrel and wherein the heat sink comprises glue applied to the integrated driver mounted thereto for encapsulation of the integrated driver and for water protection of the integrated driver.
