Technical Field
[0001] This utility model relates to the technical field of electronic water pumps, and in particular to a bushing for improving water pump noise and vibration. Background Technology
[0002] New energy vehicles are currently the dominant trend in the automotive industry. Most new energy vehicles are equipped with thermal integration modules, which typically house electronic water pumps. These water pumps serve as the primary excitation source within the thermal integration module. For example, a car electronic water pump, as described in existing technology announcement CN114109579B, includes a pump body, pump cover, stator, water-separating sleeve, rotating shaft, rotor, and controller. The pump cover is connected to the pump body, the stator is inserted into the pump body, the water-separating sleeve is inserted into the stator, the rotating shaft is located within and fixedly connected to the water-separating sleeve, and the rotor is mounted on the rotating shaft. A controller bracket is located on the side of the stator furthest from the pump cover, and the controller is mounted on the controller bracket. A first gap is formed between the controller and the bottom of the water-separating sleeve, and thermally conductive adhesive is placed in this gap, contacting both the controller and the water-separating sleeve. However, water pumps are usually rigidly connected to thermal integration modules, causing noise and vibration to be transmitted to the thermal integration module and the entire vehicle, which is detrimental to noise control.

A boss is provided on the lower part of the outer wall of the water pump body, and the mounting assembly is evenly installed on the boss. The water pump body is connected to the thermal integration module through the mounting assembly. The noise and vibration generated by the water pump body 1 will first act on the mounting assembly, and the mounting assembly will absorb part of the noise and vibration, thereby improving the noise of the thermal integration module and the whole vehicle. The structure is simple, the installation is convenient, it is conducive to parts manufacturing, and it is easy to promote and apply.
[0005] Preferably, the mounting assembly includes multiple bushings and multiple fixing ears. The multiple fixing ears are axially and evenly mounted on the boss of the water pump body. A fixing hole is opened in the middle of the fixing ear, and the bushing is installed in the fixing hole. The bolt passes through the bushing and the water pump body is mounted on the thermal integration module through the fixing ears. The noise and vibration generated by the water pump body will first act on the bushing, and the bushing will absorb part of the noise and vibration, thereby improving the noise of the thermal integration module and the whole vehicle.
