Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motor casings, and particularly relates to a casing structure. Background Art
[0002] As an important component of the motor, the design and manufacture of the motor housing have a significant impact on the motor's performance and reliability. Traditional motor housings are usually cast or stamped as a whole. Although they have high strength and rigidity, they have certain difficulties in the die-casting and processing processes. In addition, with the diversification of motor applications and the increasing demand for customization, traditional integral housings are difficult to adapt to the rapid switching and production of motors of different models and specifications. Therefore, it is of great significance to design a split housing structure that can flexibly adapt to different motor specifications, is easy to assemble and maintain, and is conducive to platform-based production.

[0019] 4) The utility model provides a casing structure that adopts a process that combines split casting and integrated processing, which not only simplifies the casting process, improves processing accuracy and production efficiency, but also reduces production and maintenance costs. It has broad application prospects and significant competitive advantages.
[0020] 5) This utility model provides a housing structure that integrates dual motors with the front housing of the transmission, achieving a high level of system integration, which is particularly important for space-constrained applications.

[0028] [First embodiment]
[0029] like Figure 1-4 The first embodiment of the present invention provides a housing structure, which is characterized in that the housing structure is connected to the gearbox housing and the motor, such as Figure 1-2 As shown, the front housing module 1 is connected to the gearbox housing, and the rear housing module 2 serves as the motor housing. In this embodiment, the rear housing module 2 houses dual motors arranged side by side, integrating the dual motors with the front housing of the gearbox, which has a high degree of system integration and is particularly important for space-constrained application scenarios. At the same time, the compact structural design can enhance the overall rigidity of the structure, reduce vibration and noise, and improve the stability and reliability of the motor during operation. Of course, those skilled in the art should be aware that other numbers of motors can also be accommodated in other arrangements inside the rear housing module 2 according to actual power requirements. These foreseeable motor arrangements and motor settings should not be used as further limitations on the scope of protection requested in this application.
[0030] The housing structure comprises a front housing module 1 and a rear housing module 2 that cooperate with each other. The housing structure is constructed from multiple independent modular housing units, which can be combined to create motor housings of varying specifications and models as needed. This highly adaptable design facilitates platform-based production and reduces production costs. The housing units have standardized internal dimensions for securing the motor's stator, rotor, and other components, enabling rapid response to changing market demands. By replacing or adjusting certain modules, new product development and production can be realized, shortening product time-to-market.
[0031] like Figure 3-4 As shown, in this embodiment, the front housing module 1 and rear housing module 2 are cast separately and then machined as a whole. Specifically, after the front and rear housing modules 1 and 2 are cast separately, they undergo preliminary machining and quality inspection. They are then assembled into a single unit using positioning and fixing components and then subjected to overall finishing. High reliability: The combination of separate casting and integrated machining ensures precise connections between modules (for example, the precision of key locations such as the motor bearing chamber and the gearbox bearing chamber, and the motor bearing chamber and the stator chamber). This improves the consistency and coordination of the overall machining, reduces potential assembly errors during subsequent assembly, ensures a tight connection and high reliability between the housing units, and guarantees stable motor operation. Furthermore, the combined separate casting and integrated machining process not only simplifies the casting process, improves machining precision and production efficiency, but also reduces production and maintenance costs, offering broad application prospects and significant competitive advantages.
[0032] like Figure 1-2As shown, in this embodiment, the front housing module 1 and the rear housing module 2 are respectively positioned and fixed by positioning members 3 and fixing members 4. Positioning members 3 employ a two-pin-on-one positioning method, including at least cylindrical pins and diamond-shaped pins. This classic two-pin-on-one positioning method ensures reliable positioning between the modules. Fixing members 4 can be made of screws, bolts, or other standard fasteners, ensuring a reliable and stable connection.
[0033] This embodiment provides a platform-based housing structure. Through modular design and standardized interfaces, it enables flexible motor housing assembly, reliable quality, and adaptability to motors of varying specifications and models. This structure not only facilitates efficient production and cost control in motor manufacturing, but also meets diverse and customized customer needs, offering broad application prospects.
[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
