Description

Technical Field

[0001] This utility model relates to the field of fan motor technology, and in particular to a lightweight fan motor housing structure that is easy to maintain. Background Technology

[0002] In traditional fan motor applications, their installation structure typically employs an integrated or fixed connection, leading to numerous inconveniences when maintenance or motor replacement is required. When existing cooling fans experience motor failure or require upgrades, the entire fan unit often needs to be disassembled, making it impossible to replace the motor module separately, significantly increasing maintenance time and operational complexity. This design flaw not only reduces product maintainability but also imposes additional cost burdens on users over long-term use.

[0003] To address the aforementioned issues, a lightweight fan motor housing structure that is easy to maintain is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing cooling fans, which often require the entire fan to be disassembled when the motor fails or needs to be upgraded, and cannot replace the motor module separately, significantly increasing maintenance time and operational complexity, this utility model provides a lightweight fan motor housing structure that is easy to maintain.

[0005] Technical solution: A lightweight fan motor housing structure that is easy to maintain, including a front cover; the front cover is provided with a number of circumferentially distributed ventilation slots; It also includes a support plate, a motor, sound insulation cotton, a housing, and a rear cover; the support plate is threaded to the rear side of the front cover; the motor is fixed to the rear side of the support plate; a ring-shaped sound insulation cotton is fixed to the front side of the support plate; the housing is threaded to the support plate; and a detachable rear cover is connected to the rear side of the housing.

[0006] Furthermore, it is particularly preferred that the support plate is provided with a number of circumferentially distributed vent holes, and the vent holes are arranged at an angle.

[0007] Furthermore, it is particularly preferred that the cover also includes elastic sheets; several elastic sheets are fixedly connected inside the rear cover; the several elastic sheets are distributed in a circumferential array along the central axis of the rear cover.

[0008] In addition, it is particularly preferred that the outer casing has several vents evenly distributed around its circumference, and that filters be detachably installed on the vents.

[0009] In addition, it is particularly preferred that the enclosure also includes a shield; the shield is rotatably connected to the outer circumferential surface of the outer shell; the shield has a number of ventilation openings evenly distributed around its circumference; and the size of the ventilation openings is consistent with the specifications provided on the outer shell.

[0010] Furthermore, it is particularly preferred that the device also includes a first magnet and a second magnet; three first magnetic elements are provided on the front and rear sides of the outer ring of the outer casing; each first magnetic element consists of two first magnets, and the two first magnets in the same group of first magnetic elements are spaced apart by an angle of thirty degrees; the spacing between each group of first magnetic elements is one hundred and twenty degrees; three second magnetic elements are provided on the front and rear sides of the inner ring of the shield; each second magnetic element consists of two second magnets, and the two second magnets in the same group of second magnetic elements are spaced apart by an angle of thirty degrees; the spacing between each group of second magnetic elements is one hundred and twenty degrees.

[0011] Beneficial effects: During the installation process, as the outer casing is screwed into the support plate, the six elastic plates will move and press against the rear of the motor. This causes the elastic plates to deform and compress inward, which can effectively fix the rear of the motor, reduce the vibration of the motor during operation, and extend its lifespan. This application has several circumferentially distributed vent holes, which are inclined; the function of the air holes is that the front surface of the motor is mounted on the support plate, and air can flow through the vent holes to cool the front surface of the motor and prevent the front end from getting too hot. The carrier plate of this application can be quickly disassembled from the front cover, and the outer shell can be directly and quickly disassembled from the carrier plate. Thus, the carrier plate and the motor are kept connected for maintenance, because only the rear shell of the motor needs to be opened. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] Example

[0016] A lightweight fan motor housing 3 and 5 structure that is easy to maintain, such as Figures 1-6 As shown, it includes a front cover 1; the front cover 1 is provided with a number of circumferentially distributed ventilation slots. It also includes a support plate 2, a motor 3, sound insulation cotton 4, a housing 5, and a rear cover 6; the support plate 2 is threadedly connected to the rear side of the front cover 1; the motor 3 is bolted to the rear side of the support plate 2; the sound insulation cotton 4 is fixedly connected to the front side of the support plate 2 in a ring shape; the housing 5 is threadedly connected to the support plate 2; and the rear side of the housing 5 is connected to a detachable rear cover 6.

[0017] The support plate 2 is provided with several circumferentially distributed vent holes, which are inclined. The function of the air holes is that the front surface of the motor 3 is mounted on the support plate 2, and air can flow through the vent holes to cool the front surface of the motor 3 and prevent the front end from getting too hot.

[0018] It also includes elastic plates 7; several elastic plates 7 are fixed inside the rear cover 6; the several elastic plates 7 are arranged in a circumferential array along the central axis of the rear cover 6; during installation, as the outer shell 5 is screwed into the bearing plate 2, the six elastic plates 7 will move and press against the rear of the motor 3, so that the elastic plates 7 will deform and compress inward, thus fully fixing the rear of the motor 3, reducing the vibration effect of the motor 3 during operation, and improving its lifespan.

[0019] The outer casing 5 has several ventilation openings evenly distributed around its perimeter, and the ventilation openings have removable filters.

[0020] It also includes a shield 8; the shield 8 is rotatably connected to the outer ring surface of the outer shell 5; the shield 8 has several ventilation openings evenly distributed around its circumference; and the size of the ventilation openings is consistent with the specifications set on the outer shell 5; during the process of starting the motor 3, the shield 8 is directly unscrewed so that the ventilation openings on the shield 8 and the outer shell 5 correspond to each other, so that outside air can enter between the outer shell 5 and the motor 3 to achieve heat dissipation on the outer surface of the motor 3.

[0021] It also includes a first magnet 9 and a second magnet 10; three first magnetic components are provided on the front and rear sides of the outer ring of the outer shell 5; each first magnetic component consists of two first magnets 9, and the two first magnets 9 in the same group of first magnetic components are spaced apart by an angle of thirty degrees; the spacing angle of each group of first magnetic components is one hundred and twenty degrees; three second magnetic components are provided on the front and rear sides of the inner ring of the shield 8; each second magnetic component consists of two second magnets 10, and the two second magnets 10 in the same group of second magnetic components are spaced apart by an angle of thirty degrees; the spacing angle of each group of second magnetic components is one hundred and twenty degrees.

[0022] The installation technology of this application has the following effects: Compared with the prior art, during the installation process, the bearing plate 2 supports the motor 3, so the bearing plate 2 can be directly screwed into the front cover 1 during installation; moreover, during the installation process, the sound insulation cotton 4 will be squeezed by the rear side of the front cover 1, so that the sound insulation cotton 4 is fully attached to the front cover 1, achieving sound insulation while also reducing the vibration between the front cover 1 and the bearing plate 2.

[0023] Similarly, during the installation process, as the outer casing 5 is screwed into the support plate 2, the six elastic plates 7 will move along with it and press against the rear of the motor 3. In this way, the elastic plates 7 will deform and compress inward, which can fully fix the rear of the motor 3, reduce the vibration effect of the motor 3 during operation, and improve its lifespan.

[0024] The heat dissipation process of this application is as follows: When the motor 3 is turned on, the shield 8 is directly unscrewed so that the vents on the shield 8 and the outer shell 5 are aligned, so that outside air can enter between the outer shell 5 and the motor 3 to dissipate heat from the outer surface of the motor 3; In order to improve the stability between the shield 8 and the outer shell 5, all the first magnets 9 and the second magnets 10 are aligned together to form a stable attraction; When the motor is turned off, only three first magnets 9 and three second magnets 10 on each side correspond to form an attraction, which can achieve the effect of shield 8 shielding the outer shell 5.

[0025] The disassembly process of this application is as follows: the support plate 2 can be quickly disassembled from the front cover 1, and the outer shell 5 can be directly and quickly disassembled from the support plate 2. Then the support plate 2 and the motor 3 are connected for maintenance, because only the rear shell of the motor 3 needs to be opened.

[0026] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
