Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan motor technology, specifically to a fan drive motor. Background Technology
[0002] A fan is a device that uses an electric motor to drive blades to rotate, thereby accelerating air circulation. It can be used in homes, offices, and for cooling electronic components. For example, a fan can be used to cool a laptop computer to prevent the electronic components inside the laptop from burning out due to overheating. Currently, commonly used fans mainly consist of a base, blades that are evenly spaced along the circumference of the base, and an electric motor that drives the base to rotate.
[0003] Computer cooling fans require a drive motor for operation. Traditional fan drive motors suffer from poor heat dissipation and high noise levels during actual use. Insufficient heat dissipation can easily lead to overheating and damage to the motor, affecting its lifespan. High noise levels can also affect the overall performance of the fan assembly and reduce the user experience. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fan drive motor, including a motor housing, wherein a plurality of evenly distributed rear heat dissipation slots are formed on the outer wall of the rear end of the motor housing, and a plurality of heat dissipation fins are fixedly installed on a circumferential outer wall of the motor housing, the plurality of heat dissipation fins being circumferentially distributed at equal intervals around the center point of the motor housing, and a noise reduction pad connecting two adjacent heat dissipation fins; a motor end cover is fixedly installed at the front end of the motor housing, and a plurality of evenly distributed inner reinforcing columns are fixedly installed inside the motor end cover, and an arc-shaped connector is fixedly connected between adjacent inner reinforcing columns; the cavity between the inner reinforcing columns and the arc-shaped connector is a front heat dissipation slot, and the front heat dissipation slot and the rear heat dissipation slot are interconnected.
[0006] Preferably, the inner reinforcing column and the arc-shaped connector adopt an integral molding structure design.
[0007] Preferably, the noise-reducing pad is made of sound-absorbing cotton material.
[0008] Preferably, a plurality of evenly distributed fixing ears are fixedly installed on one outer end of the motor end cover, and each fixing ear is provided with a fixing hole, which is a threaded hole.
[0009] Preferably, a motor rotating shaft is rotatably mounted inside the motor housing, and a threaded connection is provided on the outer wall of the top end of the motor rotating shaft.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model incorporates a noise-reducing pad wrapped around the exterior of the motor housing. This pad absorbs the noise generated by the internal structure of the motor during operation, resulting in a better sound absorption and noise reduction effect. This reduces the noise of the motor, providing a low-noise operating characteristic and preventing excessive noise from affecting people outside, thus improving the user experience.
[0012] Meanwhile, the front and rear ends of the motor of this utility model are respectively provided with a front heat dissipation groove and a rear heat dissipation groove, and the front heat dissipation groove and the rear heat dissipation groove are interconnected. This structure gives the motor of this utility model a front and rear through-body heat dissipation effect, which can effectively improve the actual use effect of the air exchange between the motor and the outside. This facilitates the front and rear through-hole air heat exchange, thereby effectively improving the internal heat dissipation performance of the drive motor of this utility model, avoiding excessive heat accumulation in the shell, improving the air heat exchange effect, and thus having good heat dissipation practicality.
[0013] Finally, the heat dissipation fins of this invention allow heat to be dissipated from the inside of the motor housing through the housing. The heat dissipation fins can also come into contact with the external environment, allowing for heat exchange between the dissipated heat and the external environment. This results in better heat conduction and heat exchange, thereby reducing the internal temperature of the fan motor, preventing overheating damage, and extending its service life.

[0021] Please see Figure 1-3 The present invention provides an embodiment of a fan drive motor, including a motor housing 1, a plurality of evenly distributed rear heat dissipation grooves 2 on the outer wall of the tail end of the motor housing 1, and a plurality of heat dissipation fins 3 fixedly installed on a ring of the outer wall of the motor housing 1, the plurality of heat dissipation fins 3 being circumferentially distributed at equal intervals through the center point of the motor housing 1.
[0022] The heat dissipation fins 3 can conduct heat from inside the motor housing 1 through the housing. The heat dissipation fins 3 can also contact the external environment, allowing the conducted heat to exchange with the external environment. This results in good heat conduction and heat exchange, which can reduce the internal temperature of the fan motor, prevent the motor from overheating and being damaged, and extend its service life.
[0023] Among them, a noise reduction pad 4 is connected between two adjacent heat dissipation fins 3. The noise reduction pad 4 is made of sound-absorbing cotton material.

[0025] The cavity between the inner reinforcing column 6 and the arc-shaped connector 7 is the front heat dissipation groove 8;
[0026] The interconnected design of the front heat dissipation slot 8 and the rear heat dissipation slot 2 gives the motor of this invention a front-to-back through-body heat dissipation effect, which can effectively improve the actual use effect of air exchange between the inside and outside of the motor. This facilitates the front-to-back through-air heat exchange, thereby effectively improving the internal heat dissipation performance of the drive motor of this invention, avoiding excessive heat accumulation in the housing, and improving the air heat exchange effect, thus having good heat dissipation practicality.
[0027] In this embodiment, in order to facilitate the production of the motor end cover 5, the inner reinforcing column 6 and the arc-shaped connecting piece 7 adopt an integrated molding structure design.
