Problems solved by technology

[0002] The electric compressor is one of the main noise components in new energy electric vehicles. In order to reduce the vibration and noise of the compressor, it is usually improved from the noise vibration transmission path generated by the compressor, such as installing a shock absorber on the compressor mounting bracket Pads, wrapping soundproof cotton outside the compressor, or adding a muffler to the suction and discharge pipelines of the compressor to reduce the vibration and noise of the compressor, which not only takes up a lot of space, but also increases the cost

Embodiment 1

[0012] as attached figure 1 As shown, a shock-absorbing and noise-reducing structure of an electric scroll compressor includes an end cover 1, a fixed scroll 2, a support plate 3, and a casing 4. The casing 4 is in a cylindrical structure, and the The top of the casing 4 is provided with an end cover 1, the inside of the casing 4 is provided with a recessed structure, a support plate 3 is installed at the bottom of the recessed structure of the casing 4, and a static scroll is arranged on the top of the support plate 3 2. A rubber gasket A5 is arranged between the end cover 1 and the casing 4, and a rubber gasket B6 is arranged at the contact part between the support plate 3 and the bottom of the concave structure of the casing 4.

[0013] The rubber gasket A5 and the rubber gasket B6 are bonded to the casing 4 by glue or glue points.

[0014] The upper and lower surfaces of the rubber gasket A5 and the rubber gasket B6 are all provided with raised floating points.

Abstract

The invention discloses a damping and noise reduction structure of an electric scroll compressor. The damping and noise reduction structure comprises an end cover, a static vortex plate, a supportingdisc and a machine shell, wherein the machine shell is of a cylindrical structure, the end cover is arranged at the top of the shell, a concave structure is arranged in the machine shell, the supporting disc is arranged at the bottom of the sunken structure of the machine shell, the static vortex plate is arranged on the upper portion of the supporting disc, a rubber gasket A is arranged between the end cover and the machine shell, a rubber gasket B is arranged at the contact part of the supporting disc and the bottom of the sunken structure of the machine shell, the rubber gasket A and the rubber gasket B are bonded to the machine shell through glue or glue points; and the upper surface and the lower surface of the rubber gasket A and the rubber gasket B are provided with raised floatingpoints correspondingly. The damping and noise reduction structure has the advantages that the vibration can be reduced during acceleration and deceleration operation of the compressor, and the noise produced by the compressor can be reduced.
