Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a high-temperature resistant carbon fiber reinforced composite material motor casing. Background Art

[0002] Existing motor casings mostly adopt an integrated welded structure. When the internal motor fails, it is difficult to disassemble quickly, which is not conducive to the inspection and maintenance of the internal motor. The heat dissipation, anti-interference and sealing and waterproofing capabilities of the casing are limited, which is not conducive to the stable operation of the motor in extreme environments. A Chinese patent application, numbered 202220319296.3, discloses a "composite motor housing with auxiliary heat dissipation function." The housing comprises a main body, an annular hanging ring, and heat sinks. The main body is provided with a nameplate, and mounting plates are provided on both sides of the annular hanging ring. A shaft is provided on one side of the annular hanging ring, which passes through the mounting plates and is provided with a latch. This composite motor housing with auxiliary heat dissipation function differs from existing technologies in that, during actual use, the nameplate is pushed to move, which in turn drives the long plate to first push the sliding body, thereby driving the latch to move and unlock, and then pushing the rectangular body to deflect, which in turn drives the annular hanging ring to deflect and retract, thus avoiding the need for removal of the annular hanging ring. This also facilitates and quickly lowers the overall height of the motor, making it more convenient. The nameplate completely covers and temporarily locks the annular hanging ring, while exposing the heat sinks previously covered by the nameplate, thereby ensuring the main body's appearance is intact and clean, while also increasing heat dissipation efficiency. However, the motor housing is difficult to install and remove, making it difficult to inspect and maintain in the event of a fault. The housing also has limited heat dissipation, anti-interference, and sealing capabilities, making the motor less adaptable to extreme environments. Utility Model Content
