[0014] Furthermore, the height of the heat dissipation guide plate is less than or equal to half the distance between the outer cylinder and the inner cylinder.

[0015] The beneficial effects of this utility model are as follows: the casing is made of aluminum or aluminum alloy to form the inner and outer cylinders in one piece, which not only reduces cost but also provides excellent heat dissipation. An airflow channel is provided between the inner and outer cylinders, allowing axial airflow to pass through, which, in conjunction with the cooling fan, greatly enhances heat dissipation performance. The inner cylinder has a heat dissipation guide plate extending into the airflow channel, which serves to guide airflow and dissipate heat, further improving heat dissipation performance.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a motor housing structure of this utility model is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0023] Please refer to Figures 1 and 2. An electric motor housing structure includes components integrally formed from aluminum or aluminum alloy.

[0024] The inner cylinder 100 has a movement mounting cavity 110 inside, and several heat dissipation guide plates 120 are provided on the outer wall of the inner cylinder 100.

[0025] The outer cylinder 200 is integrally connected to the inner cylinder 100. There are several axially connected air guide channels 300 between the outer cylinder 200 and the inner cylinder 100. Several heat dissipation ribs 210 are provided on the outer wall of the outer cylinder 200.

[0026] The casing is constructed from a single piece of aluminum or aluminum alloy, forming the inner cylinder 100 and outer cylinder 200. This design not only reduces cost but also provides excellent heat dissipation. An airflow channel 300 is provided between the inner cylinder 100 and outer cylinder 200, allowing axial airflow to pass through. Combined with a cooling fan, this significantly enhances heat dissipation performance. The inner cylinder 100 features a heat dissipation guide plate 120 extending into the airflow channel 300, which serves both to guide airflow and dissipate heat, further improving heat dissipation performance. Heat dissipation ribs 210 are also provided on the outer wall of the outer cylinder 200, increasing the outward heat dissipation area.

[0027] Referring to Figures 1 and 2, a bolt sleeve 400 is also provided between the inner cylinder 100 and the outer cylinder 200. The bolt sleeve 400 has bolt holes for bolts to pass through. That is, the bolt sleeve 400 can be used to easily connect the front and rear covers.

[0028] Please refer to Figures 1 and 2. There are two bolt sleeves symmetrically arranged at 400mm. The symmetrical arrangement ensures stable connection and balanced force.

[0029] Referring to Figures 1 and 2, the outer cylinder 200 has a recessed portion 220, which is connected to the inner cylinder 100. The recessed portion 220 not only improves the connection strength but also provides a convenient grip due to its surface recess.

[0030] Referring to Figures 1 and 2, the system also includes a connecting rib 500, and the outer cylinder 200 and the inner cylinder 100 are connected at the ends away from the recess 220 via the connecting rib 500. Preferably, the line connecting the recess 220 and the connecting rib 500 is perpendicular to the line connecting the two bolt cylinders 400.

[0031] Referring to Figure 2, the mechanism also includes a stator winding 600. The outer wall of the stator winding 600 has several glue-filling grooves 610. The stator winding 600 is positioned within the movement mounting cavity 110 using adhesive within the glue-filling grooves 610. The stator winding 600 is connected to the inner cylinder 100 via the glue-filling grooves 610, ensuring a stable connection and tight surface contact, facilitating heat transfer and thus heat dissipation.

[0032] Referring to Figures 1 and 2, the air guide channel 300 is divided into three sections. Simply put, the air guide channel 300 is divided by the connecting rib 500, the bolt sleeve 400, and the recess 220.

[0033] Please refer to Figures 1 and 2. Each air duct 300 is provided with two spaced-apart heat dissipation air guide plates 120.

[0034] Preferably, the height of the heat dissipation guide plate 120 is less than or equal to half the distance between the outer cylinder 200 and the inner cylinder 100.

[0035] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0037] In summary, the motor housing structure provided by this utility model, in which the inner and outer cylinders are integrally formed from aluminum or aluminum alloy, not only offers low cost but also superior heat dissipation. An airflow channel is provided between the inner and outer cylinders, allowing axial airflow to pass through, which, in conjunction with a cooling fan, greatly enhances heat dissipation performance. The inner cylinder has a heat dissipation guide plate extending into the airflow channel, serving both airflow guidance and heat dissipation functions, further improving heat dissipation performance. Heat dissipation ribs are also provided on the outer wall of the outer cylinder, increasing the outward heat dissipation area.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
