Description

Technical Field

[0001] This utility model relates to the field of motor structure technology, specifically to a motor housing with dual heat dissipation ducts. Background Technology

[0002] A motor housing is a casing used to enclose a motor, primarily made of stainless steel, aluminum alloy, or other materials through a one-piece die-casting process. Currently, common heat-dissipating motor housings primarily achieve their cooling effect by installing heat sinks on the surface of the housing or by creating openings in the housing to facilitate airflow.

[0003] Most existing motors use heat sink fins for heat dissipation. To improve the heat dissipation efficiency, some motors are equipped with internal cooling fans. However, these fans operate independently and require a separate motor to drive them. These independent motors are prone to damage, rendering the fans unusable and reducing the overall heat dissipation efficiency. Furthermore, when the motor is cooling down, only a single airflow can be formed inside, resulting in low heat dissipation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a motor housing with dual heat dissipation ducts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor housing with dual heat dissipation ducts, comprising a front housing: a bracket is provided at the bottom of the front housing, multiple ventilation openings are provided at one end of both sides of the outer surface of the front housing, a dustproof net is provided at one end of both sides of the inner surface of the front housing, a drive shaft is rotatably mounted at the middle position of one end of the front housing, and a fan blade is provided at the other end of the outer surface of the drive shaft.

When the motor is working, the rotation of the drive shaft can drive the fan blades to rotate, eliminating the need to install a cooling fan inside the motor. This avoids the reduction in the cooling effect of the motor if the cooling fan is damaged. Furthermore, when the motor is working, the fan blades and vents work together to form two air channels inside the motor, improving the cooling effect of the motor.

[0013] Preferably, a limiting port is provided at the middle position of one end of the first partition and the second partition, and the first partition and the second partition are rotatably connected to the drive shaft through the limiting port.

[0014] By adopting the above technical solution, the limiting ports on the first partition and the second partition are connected by a transmission shaft, so that the transmission shaft can rotate stably on the first partition and the second partition.

[0015] Preferably, one end of the first partition and the second partition is provided with a plurality of through holes, and the interior of the front housing and the interior of the rear housing are connected through the through holes.

[0016] By adopting the above technical solution, when the motor is working, the rotation of the fan blades drives the high-temperature air inside the motor to flow to the outside of the motor, and also allows the low-temperature air from the outside to enter the motor through the through hole, thereby cooling the motor.

[0017] Preferably, the front housing and the rear housing are sleeved together, the opening position of the vent on the front housing corresponds to the opening position of the mounting groove, and a retaining element is provided at the other end of the inner surface of the front housing and one end of the inner surface of the rear housing.

The main gear is provided at one end of the outer surface of the transmission shaft near the first partition, and the secondary gear is provided at one end of the first partition with a small fan blade at one end. The main gear on the transmission shaft meshes with the secondary gear on the first partition.

[0020] By adopting the above technical solution, when the transmission shaft rotates, it drives the main gear to rotate, which in turn drives the secondary gear to rotate, so that the small fan blades on the secondary gear can rotate accordingly, assisting the air outlet of the air duct.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the motor housing with dual heat dissipation air ducts has fan blades installed on the motor's drive shaft, eliminating the need for an independent motor drive. When the motor is working, it can drive the fan blades to rotate, solving the problem of the cooling fan being damaged and affecting the motor's heat dissipation efficiency. Furthermore, through the ventilation openings on both sides and the fan blades, two air ducts are formed inside the front housing. The through holes on the first and second partitions allow the two air ducts inside the front housing to be dispersed into multiple air ducts, expanding the heat dissipation area of ​​the air ducts.
