[0040] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0041] Example 1

[0042] like Figs. 1-6 As shown in this embodiment, an aluminum alloy die-cast motor housing is provided, including a housing 1. The front and rear ends of the housing 1 are respectively provided with a front end cover 3 and a rear end cover 2. A through hole 302 is opened in the center of the front end cover 3. A stabilizing ring 10 is provided inside the through hole 302. Multiple mounting grooves 101 are opened on the outer wall of the housing 1. A heat dissipation component 4 is provided in each mounting groove 101. The heat dissipation component 4 includes an arc plate 401, which is disposed in the mounting groove 101. Multiple inner fins 402 are evenly distributed on the inner wall of the arc plate 401, and the ends of the inner fins 402 abut against the side wall of the mounting groove 101. Multiple outer fins 403 are evenly distributed on the outer wall of the arc plate 401. A sound insulation strip 5 is provided between two adjacent inner fins 402 to effectively isolate and reduce the noise generated during motor operation and improve the motor's quietness performance.

[0043] The arc plate 401, multiple inner fin plates 402, and multiple outer fin plates 403 are integrally formed.

[0044] The outer shell 1, arc plate 401, inner fin plate 402 and outer fin plate 403 are made of aluminum alloy.

[0045] The front end face of the shell 1 is provided with a sealing groove 102, and a sealing gasket 7 is arranged in the sealing groove 102 to seal the connection between the shell 1 and the front end cover 3.

[0046] Working process:

[0047] When the motor is running, the heat generated inside is transferred to the shell 1 by heat conduction. At this time, the heat dissipation assembly 4 begins to play a role. The inner fin plate 402 closely fits on the side wall of the mounting groove 101, efficiently transferring heat to the arc plate 401. At the same time, the outer fin plate 403 increases the heat dissipation area, so that the heat can be dissipated to the air more quickly. In this process, the soundproof cotton 5 effectively isolates the noise generated when the motor is running, reducing the impact of noise on the surrounding environment. In addition, the sealing gasket 7 ensures the tight connection between the shell 1 and the front end cover 3, preventing external factors from entering and ensuring the stable operation of the motor.

[0048] Example two

[0049] As shown in Figs. 1-6 Based on example one, in this embodiment, the rear end cover 2 is fixed to the rear end of the shell 1, and the front end cover 3 is detachably connected to the front end of the shell 1.

[0050] One end of the arc plate 401 is fixed to the front end cover 3.

[0051] Both sides of the arc plate 401 are provided with a plug-in edge 4011, and both sides of the mounting groove 101 are provided with a plug-in groove 1011 for the plug-in edge 4011.

[0052] The shell 1 is evenly provided with a plurality of ear blocks 6, and the plurality of ear blocks 6 are each provided with a second connecting hole 601. The front end cover 3 is evenly provided with a plurality of first connecting holes 301 matched with the second connecting holes 601. When the front end cover 3 is installed on the shell 1, the first connecting holes 301 on the front end cover 3 are aligned with the plurality of second connecting holes 601 on the shell 1, and then the second connecting holes 601 and the first connecting holes 301 are matched with the screw rod and the screw cap to fix and install the front end cover 3 on the shell 1.

[0053] Working process:

[0054] Based on example one, the aluminum alloy die casting of the motor shell in this embodiment is installed by fixing one end of the arc plate 401 of the heat dissipation assembly 4 to the front end cover 3 and ensuring that the plug-in edge 4011 of the arc plate 401 is aligned with the plug-in groove 1011 of the mounting groove 101 on the shell 1. Then, the front end cover 3 (with the fixed arc plate 401) is placed close to the front end of the shell 1, so that the plug-in edge 4011 is smoothly inserted into the plug-in groove 1011, realizing the preliminary connection of the arc plate 401 and the shell 1.

[0055] The first connecting hole 301 on the front cover 3 is aligned one-to-one with the second connecting holes 601 of the multiple lugs 6 on the outer casing 1. Finally, using fasteners such as screws and nuts, the front cover 3 is securely fixed to the outer casing 1 through the cooperation of the first connecting hole 301 and the second connecting hole 601. In this way, the aluminum alloy die-cast part of the motor housing is assembled as a whole, which not only ensures heat dissipation but also realizes the detachable connection of the front cover 3, facilitating subsequent maintenance and repair.

[0056] Example 3

[0057] like Figs. 1-3 As shown, based on Embodiment 2, in order to achieve stable support for the outer shell 1, two L-shaped support frames 8 are symmetrically arranged below the outer shell 1, and a third connecting hole 801 is provided on the side wall of the two support frames 8; a reinforcing rib 9 is provided at the bend of the support frame 8.

[0058] Work process:

[0059] First, align the upper end of the support frame 8 with the predetermined position below the housing 1, ensuring that the third connecting hole 801 of the support frame 8 is fully aligned with the corresponding second connecting hole 601 on the housing 1. Then, use appropriate fasteners (such as screws or nuts) to securely connect the support frame 8 to the housing 1 through the third connecting hole 801 and the second connecting hole 601. After connection, the support frame 8 will provide stable support for the housing 1, ensuring the stability and safety of the die-cast aluminum alloy motor housing during operation.
