Description

Technical Field

[0001] The utility model belongs to the field of flange covers, and in particular relates to a vibration mitigation structure of a flange cover. Background Art

[0002] The flange cover is also called a blind plate, and some are also called a blind flange or a pipe plug. It is a flange without a hole in the middle, used to seal the pipe opening. The function is the same as that of the head and the pipe cap, except that the blind plate seal is a detachable sealing device, and the seal of the head is not intended to be opened again. There are many types of sealing surfaces, including flat surfaces, convex surfaces, concave and convex surfaces, tongue and groove surfaces, and ring connection surfaces. Automobile air-conditioning blowers usually include a flange cover structure, and the motor is installed in the flange cover structure. The use requirements of automobile motors in automobiles are getting higher and higher, and the performance requirements are becoming more and more stringent. At present, with the development of the automobile industry, users have more and more stringent requirements on the experience of the in-car environment. As a component in the cockpit, the vibration and noise generated during the operation of the blower will have a bad driving experience for the driver and passengers.

[0003] The patent application with publication number CN211830444U discloses a motor flange assembly, which includes a flange body and a flange cover connected to the flange body, wherein the flange body has an internal cavity, the bottom of the internal cavity is integrally molded with a bottom buffer, and the flange cover has a through hole communicating with the internal cavity, and the top of the through hole is integrally molded with a top buffer. Such an arrangement can achieve a good shock absorption effect, and the integral injection molding can simplify the installation process.

[0004] The above application simply places a rubber pad inside the flange cover to reduce the shock of the motor. However, different rubber pads may need to be replaced when facing motors of different sizes. This will cause the position of the rubber pad to be not fixed enough and easy to shift, affecting the shock absorption effect. If the rubber pad and the flange cover are integrated, it is necessary to replace the matching flange cover, which is inconvenient to use and has great limitations.

[0005] In summary, the utility model provides a flange cover vibration mitigation structure to solve the above problems. Utility Model Content
