Description

External machine of air conditioner for vehicle

[ field of technology ]

The present invention relates to an air conditioner external unit for a vehicle, and more particularly, to an air conditioner external unit for a vehicle having a vibration restricting member.

[ background Art ]

Compressors have become increasingly popular in the life of people today, such as air conditioning, refrigerators, and the like. With the increasing demands of people for comfort, vibration and noise during operation of compressors are becoming an increasing concern. And these vibrations and noise mainly originate from resonances with the mounting during operation of the compressor itself.

The known approaches to improve vibration damping and noise reduction of compressors are mostly to fix the compressor indirectly on the mounting base through springs or elastic elements such as rubber, so as to reduce hard contact and thereby realize vibration damping and noise reduction. But, in contrast, the introduction of the elastic member, which results in a compressor having a wider and larger swing amplitude than in the past, is likely to adversely affect the life of the piping and the normal operation of the compressor if it is not effectively restrained.

In view of the foregoing, there is a need for an improved vehicle air conditioner outdoor unit that overcomes the above-mentioned drawbacks.

[ detailed description ] of the invention

Referring to fig. 1 to 4, the present embodiment relates to an air conditioner outdoor unit for a vehicle, which is configured to be mounted on a configuration surface 70 of the vehicle, and includes an outdoor unit body 100 having a mounting base 10, and an elastic vibration-damping pad 30 disposed between the configuration surface 70 of the vehicle and the mounting base 10. Since the main design improvement of the present application focuses on the compressor and the vibration reduction system thereof, it is known that conventional constituent parts such as an evaporator, a condenser and the like in the drawings are omitted in order that the main content of the present application can be clearly illustrated.

The vehicle air conditioner external unit further comprises a vibration restraining component 50, the vibration restraining component 50 comprises a first component 501 and a second component 503, the first component 501 is provided with a shaft post 5011 arranged parallel to the configuration surface 70, the second component 503 is provided with a ferrule 5031 surrounding the shaft post 501, the shaft post 5011 can move within the restraint range of the ferrule 5031, the first component 501 is assembled on the configuration surface 70 or the mounting seat 10, and the second component 503 is assembled on the mounting seat 10 or the configuration surface 70 respectively. The first part 501 and the second part 503, which are separately installed on the configuration surface 70 and the mounting base 10, restrict the swing space of the vehicle air conditioner external unit installed above the elastic vibration damping pad 30 in the vibration environment, and optimize the working stability of the product while reducing vibration and noise. The axial column 5011 can move within the constrained range of the ferrule 5031, namely, the axial column 5011 is constrained in the vertical direction, the end face of the axial column 5011 and the inner wall face of the ferrule 5031 are arranged at intervals, and a certain degree of freedom of movement is further provided in the horizontal direction. Moreover, both the end face and the outer cylindrical surface of the post 5011 are coated with a soft skin 5011a to ensure soft collision when contact is provided, reducing noise.

With continued reference to the drawings, in this embodiment, the first component 501 is assembled to the configuration surface 70, and the second component 503 is assembled to the mounting base 10. The arrangement surface 70 serves as a reference surface for vibration, and the function of determining the reference of the shaft stud 501 of the first member 501 can be well achieved, and the mounting accuracy is also better grasped. At this time, the ferrule 5031 of the second member 503 is correspondingly disposed on the mount 10. The second part 503 has a mounting hole axis S parallel to the shaft post 5011, the second part 503 is rotatably pivoted on the mounting hole axis S, and the second part 503 further has a limiting part for limiting the rotation angle of the second part around the mounting hole axis S. The limit part design further provides a certain swinging space on the basis of the restraint of the ferrule 5031, and provides a more optimized restraint space under the condition that the structural size of the ferrule 5031 is limited by combining the ferrule 5031. In this embodiment, the limiting portion is specifically a limiting pin 5033 parallel to the mounting hole axis S and protruding into the lower space of the mounting seat 10. The mounting surface of the outer machine body 100 is generally rectangular, and the vehicle air conditioner outer machine at least comprises two vibration restraining members 50 arranged on two opposite sides of the rectangular mounting surface, so as to effectively restrain vibration of the vehicle air conditioner outer machine.
