Description

Technical Field

[0001] This utility model relates to the technical field of hollow motor housing aluminum profiles, specifically a hollow motor housing aluminum profile. Background Technology

[0002] In the motor manufacturing process, the motor housing, as one of the core components, has a significant impact on the overall performance and subsequent maintenance of the motor due to its assembly process with the motor end cover. Currently, the installation of the aluminum profile of the motor housing and the motor end cover commonly employs welding or adhesive bonding. While welding achieves a high-strength connection, removing the weld points is complex when the motor needs disassembly for maintenance, easily damaging the aluminum profile's structure and increasing the risk of the housing being scrapped. Adhesive bonding requires the use of chemical solvents to dissolve the adhesive during disassembly and maintenance, which can leave harmful residues that corrode internal motor components. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model proposes a hollow motor housing aluminum profile. The purpose is to solve the problem that the existing installation of motor housing aluminum profiles and motor end covers generally uses welding or adhesive bonding. When the motor needs to be disassembled for maintenance, welding requires breaking the weld joints, which is complicated and easily damages the aluminum profile body; adhesive bonding requires the use of chemical solvents to dissolve the adhesive, which can easily leave residues that corrode internal components.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A hollow motor housing aluminum profile includes an outer shell and an inner shell; the outer shell and the inner shell together form a circular structure, the outer shell and the inner shell are fixedly connected, and a plurality of irregularly shaped mounting holes are evenly distributed along the circumferential direction at the connection between the outer shell and the inner shell, and the plurality of irregularly shaped mounting holes are respectively used for engaging with the mounting positions corresponding to the motor end cover.

[0006] Preferably, an aluminum spring is provided inside the irregularly shaped mounting hole.

[0007] Preferably, the irregularly shaped mounting hole has a wavy structure near the inner wall of the inner shell.

[0008] Preferably, the total length L of the irregular mounting hole is 26.50 to 28.50 mm.

[0009] Preferably, four flow channels are evenly distributed along the circumferential direction at the connection between the outer shell and the inner shell, and each flow channel passes through the outer side wall of the outer shell and the inner side wall of the inner shell in a radial direction.

[0010] Preferably, the inner walls of the four flow channels are all spiral-shaped.

[0011] The technical solution provided by this utility model can include the following beneficial effects:

[0012] In this design, several irregularly shaped mounting holes are evenly distributed along the circumference at the connection between the outer shell and the inner shell. These holes can engage with the corresponding mounting positions on the motor end cover, enabling the detachable installation of the hollow motor housing aluminum profile. Compared to traditional welding or adhesive bonding methods, this design uses a snap-fit ​​assembly. When the motor needs to be disassembled for maintenance, there is no need for complex solder joint removal or the use of chemical solvents to dissolve the adhesive. This allows for convenient disassembly and reassembly of the hollow motor housing aluminum profile, avoiding damage to the aluminum profile structure caused by solder joint removal and the risk of harmful residues corroding motor components due to the use of chemical solvents to dissolve the adhesive, thereby improving the motor's service life.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] In the description of this utility model, it should be understood that the terms "length", "middle", "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] A hollow motor housing aluminum profile, characterized in that: it includes an outer shell 1 and an inner shell 2; the outer shell 1 and the inner shell 2 together form a circular structure, the outer shell 1 and the inner shell 2 are fixedly connected, and a plurality of irregularly shaped mounting holes 3 are evenly distributed along the circumferential direction at the connection between the outer shell 1 and the inner shell 2, and the plurality of irregularly shaped mounting holes 3 are respectively used to engage with the mounting positions corresponding to the motor end cover (not shown in the figure).

[0021] One type of hollow motor housing aluminum profile in this solution, such as Figure 1 As shown, the outer shell 1 and the inner shell 2 together form a circular structure, which effectively enhances the structural strength of the hollow motor housing aluminum profile. Since the connection between the outer shell 1 and the inner shell 2 is provided with several irregularly shaped mounting holes 3 evenly distributed along the circumference, these holes 3 can engage with the corresponding mounting positions on the motor end cover, enabling the detachable installation of the hollow motor housing aluminum profile. Compared to traditional welding or adhesive bonding methods, this solution uses a snap-fit ​​assembly. When the motor needs to be disassembled for maintenance, there is no need for complex weld point removal operations or the use of chemical solvents to dissolve the adhesive. This allows for convenient disassembly and reassembly of the hollow motor housing aluminum profile, avoiding damage to the aluminum profile structure caused by weld point removal and the risk of harmful substances remaining and corroding motor components due to the use of chemical solvents to dissolve the adhesive, thereby improving the motor's service life.

[0022] Preferably, an aluminum spring clip 30 is provided inside the irregularly shaped mounting hole 3. In this embodiment, as shown... Figure 2 As shown, when the hollow motor housing aluminum profile is snapped into the motor end cover, the aluminum spring sheet 30 can absorb assembly stress and motor operation vibration, avoiding connection loosening or structural fatigue caused by long-term vibration, and improving the vibration resistance and service life of the hollow motor housing aluminum profile.

[0023] Preferably, the irregularly shaped mounting hole 3 has a wavy structure near the inner wall of the inner shell 2. In this embodiment, as shown... Figure 2 As shown, since the irregular mounting hole 3 has a wavy structure near the inner wall of the inner shell 2, this wavy structure is a specific structural feature of the irregular mounting hole 3. When it is engaged with the corresponding mounting position of the motor end cover, the morphological adaptability enhances the stability of the connection.

[0024] Preferably, the total length L of the irregularly shaped mounting hole 3 is 26.50–28.50 mm. In this embodiment, as shown... Figure 2 As shown, the total length L of the irregular mounting hole 3 is 27.15mm. This length precisely matches the dimensions of the mounting position corresponding to the motor end cover, ensuring full contact between the irregular mounting hole 3 and the mating surface of the motor end cover during snap-fit, and avoiding problems such as loose snap-fit ​​or excessive assembly gap caused by dimensional deviation.

[0025] Preferably, four flow channels 4 are evenly distributed along the circumferential direction at the connection between the outer shell 1 and the inner shell 2, and each flow channel 4 passes radially through the outer side wall of the outer shell 1 and the inner side wall of the inner shell 2. In this embodiment, as shown... Figure 1 As shown, during motor operation, the arrangement of the four flow channels 4 helps to guide the airflow inside the motor to be smoothly discharged to the outside of the motor. By accelerating the outward transfer of heat, the heat dissipation efficiency of the entire motor is improved, thereby providing a reliable guarantee for the thermal stability of the motor during operation.

[0026] Preferably, the inner walls of all four flow channels 4 have a spiral structure. In this embodiment, as shown... Figure 1 As shown, since the inner wall of the flow channel 4 has a spiral structure, the inner wall of the flow channel 4 can force the airflow inside the motor to flow along the spiral track, which can further extend the flow path of the airflow inside the flow channel 4, increase the heat exchange time between the airflow and the inner wall of the flow channel 4, and more fully remove the heat generated by the motor operation, significantly improving the heat exchange efficiency.

[0027] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
