Description

Technical Field

[0001] This utility model relates to the field of motor equipment technology, specifically to an electric motor housing. Background Technology

[0002] As a key protective component of the electric motor, the motor housing not only provides a robust physical protective barrier for the internal windings, stator, rotor and other core components, effectively resisting damage caused by external mechanical impacts, collisions or compression, but also prevents impurities such as dust, moisture and oil from entering the interior through a sealed design, avoiding aging of insulation materials, short circuits or corrosion of mechanical parts, thereby extending the service life of the equipment.

[0003] During operation, motors generate relatively strong vibrations. These vibrations are not only transmitted to the exhaust fan frame, causing noise and affecting the quality of the operating environment, but also cause continuous impact and wear on the internal components of the motor over a long period of time. This accelerates the aging and damage of the components, greatly shortens the service life of the motor, and increases the cost of equipment maintenance and replacement.

[0004] To address the aforementioned issues, we propose an electric motor housing. Utility Model Content

[0005] The purpose of this invention is to provide an electric motor housing to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric motor housing, comprising an electric motor housing body and a top cover, wherein the top cover is installed on the top of the electric motor housing body, a positioning ring is fixedly provided at the bottom of the outer wall of the electric motor housing body, and four equally spaced positioning grooves are opened on the top outer wall of the positioning ring, a rotating block is rotatably connected to the inner wall of the four positioning grooves, a spring damper is installed on the outer wall of one end of the rotating block, and a support plate is fixedly provided on the outer wall of the other end of the spring damper.

[0007] Preferably, positioning rods are fixedly provided on the inner walls of both sides of the four positioning slots, and a rotating hole is opened on the outer wall of one end of the rotating block. The outer wall of the positioning rod is movably connected to the inner wall of the rotating hole.

[0008] Preferably, a rubber pad is fixedly provided on the outer wall of one end of the support plate.

[0009] Preferably, the top outer wall of the top cover has heat dissipation holes that are evenly distributed.

[0010] Preferably, a wiring hole is provided on one side of the top of the top cover.

[0011] Preferably, the outer wall of the top cover is fixed with positioning plates that are evenly distributed. The outer wall of the positioning plate has positioning holes. A rubber ring is bonded to the bottom outer wall of the positioning plate. The positioning holes and the inner wall of the rubber ring are fitted with matching bolts.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] The spring damper and support plate located at the bottom of the outer wall of the motor housing, with the rubber pad at one end of the support plate tightly pressed against the inner wall of the exhaust fan frame, compress and limit the bottom of the motor housing. The spring damper can effectively absorb and buffer the vibration generated during motor operation, reduce the noise caused by vibration, and also reduce the wear and tear on the internal components of the motor, thus extending the service life of the motor.

[0022] Example 1

[0023] Refer to the instruction manual appendix Figure 1-3 An electric motor housing includes an electric motor housing body 1 and a top cover 2. The top cover 2 is installed on the top of the electric motor housing body 1. A positioning ring 6 is fixedly installed at the bottom of the outer wall of the electric motor housing body 1. Four positioning grooves 7 are opened at equal intervals on the top outer wall of the positioning ring 6. Positioning rods 8 are fixedly installed on the inner walls on both sides of the four positioning grooves 7. A rotating hole 10 opened on the outer wall of one end of a rotating block 9 is movably connected to the outer wall of the positioning rods 8, so that the rotating block 9 can rotate in the positioning grooves 7.

[0024] Example 2

[0025] Based on Embodiment 1, a spring damper 11 is installed on the outer wall of the other end of the rotating block 9. A support plate 12 is fixedly installed on the outer wall of the other end of the spring damper 11. A rubber pad 13 is fixedly installed on the outer wall of one end of the support plate 12. When the motor housing is used in the exhaust fan, the support plate 12 installed on one end of the four spring dampers 11 is supported on the inner wall of the exhaust hood by the rubber pad 13. The buffering and shock absorption effect of the spring damper 11 and the anti-slip and further buffering effect of the rubber pad 13 are used to improve the stability of the motor in the exhaust hood.

[0026] Example 3

[0027] Based on Embodiment 1, the top outer wall of the top cover 2 has equidistantly distributed heat dissipation holes 5 to facilitate the dissipation of heat generated during motor operation. A wiring hole 14 is provided on one side of the top of the top cover 2 to facilitate the connection of the motor with external circuits. At the same time, equidistantly distributed positioning plates 3 are fixedly installed on the outer wall of the top cover 2. Positioning holes are provided on the outer wall of the positioning plates 3. A rubber ring 4 is glued to the bottom outer wall of the positioning plates 3. During installation, the bolts are passed through the positioning holes and the rubber ring 4 and tightened in the corresponding positions. The rubber ring 4 helps to improve the shock absorption effect of this utility model.

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual appendix Figure 1-3 When using this utility model, the motor parts are installed inside the motor housing body 1 and the top cover 2. The motor-related circuits are connected to the external circuit through the wiring hole 14 on one side of the top of the top cover 2. At this time, the utility model is installed in the exhaust fan frame and fixed to one end of the exhaust fan frame by using bolts through the positioning plate 3 and the inner wall of the rubber ring 4. The top end of the motor is fixed. At this time, the spring damper 11 and the rotating block 9 rotate. The support plates 12 installed at one end of the four spring dampers 11 are supported on the four inner walls of the exhaust fan frame plate by rubber pads 13. The elasticity of the spring damper 11 and the tight fit between the rubber pads 13 and the inner walls of the exhaust cover effectively buffer the vibration generated when the motor is running, reduce noise and enhance the stability of the motor operation. The heat generated by the motor operation will be naturally dissipated through the heat dissipation holes 5 evenly distributed on the top of the top cover 2, which is conducive to improving the heat dissipation effect of the motor.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
