Compressors are divided into two types: fixed displacement and variable displacement. According to different working modes, compressors can generally be divided into reciprocating and rotary types. Common reciprocating compressors are crankshaft connecting rod type and axial piston type, and common rotary compressors are rotary blade type and scroll type. The clutch suction cup device is used for automobile air conditioning compressors. The drive of the compressor is to transmit the power of the engine to the suction cup that is electromagnetically attracted to the pulley through the pulley, and then to the compressor.

It includes a wheel hub and a suction cup connected to the outer periphery of the wheel hub, a front plate is provided on the wheel hub, a spring steel sheet is provided between the front plate and the wheel hub, one side of the spring steel sheet is connected to the wheel hub through a first rivet, and the other side is connected to the suction cup through a second rivet, and a shock-absorbing sleeve is provided on the surface of the spring steel sheet. The noise reduction device of the utility model has a simple structure. By coating the shock-absorbing sleeve on the surface of the spring steel sheet, the noise of the clutch suction cup when the automobile air-conditioning compressor is working can be effectively reduced, thereby improving the driving experience; at the same time, the process of coating the shock-absorbing sleeve on the spring steel sheet is simple, stable, efficient, and low-cost.

[0004] However, during use, the utility model only performs noise reduction treatment on the inside of the suction cup, and no structure is set on the outside of the suction cup, which may result in poor noise reduction effect of the suction cup, affecting the practicability of the device and failing to meet production needs. Therefore, a noise reduction device for a clutch suction cup of an automobile air-conditioning compressor is proposed to solve the above-mentioned problems. Utility Model Content

[0009] Furthermore, a mounting seat is fixedly connected to the front of the suction cup, and a fixing bolt extending into the interior of the clutch body is threadedly connected to the top of the mounting seat.

[0010] Furthermore, a cover plate is hinged on the top of the protective shell, a mounting opening is provided inside the cover plate, and a through opening communicating with the outside is provided on the inner bottom wall of the protective shell.

[0011] Furthermore, a mounting tube is fixedly connected to the front of the cover plate, a return spring is fixedly connected to the inner top wall of the mounting tube, and an elastic block extending to the bottom of the mounting tube is fixedly connected to the bottom end of the return spring.

[0012] Furthermore, a fixing seat is fixedly installed on the front side of the protective shell, the elastic block passes through the fixing seat, and a mounting hole adapted to the elastic block is opened inside the fixing seat.

[0013] Furthermore, a sliding block is provided on one side of the installation tube, a connecting block is fixedly connected between the sliding block and the elastic clamping block, and a sliding groove adapted to the connecting block is provided inside the installation tube.

[0014] Compared with the prior art, the utility model provides a noise reduction device for a clutch suction cup of an automobile air-conditioning compressor, which has the following beneficial effects:
