Description

Engine with air inlet connecting pipe and air conditioner compressor mounting structure integrated Technical Field The utility model relates to the technical field of engine manufacturing, in particular to an engine with an air inlet connecting pipe integrated air conditioner compressor mounting structure. Background In the prior art, an engine air inlet connecting pipe and an air conditioner compressor are generally in a separated mounting structure, the air inlet connecting pipe of a traditional engine is arranged on the side face of the engine and is connected with an engine cylinder body or a frame through an independent bracket, and the air conditioner compressor is also provided with an independent mounting bracket for fixing. In addition, vibration generated when the engine and the air conditioner compressor work is transmitted through the brackets, resonance phenomenon is easy to occur, larger noise is further generated, and driving experience is reduced. With the development of the automobile industry, the requirements on the space utilization rate and the overall performance of an engine compartment are continuously improved, and the requirements on the traditional separated mounting structure are difficult to meet. While some of the techniques attempt to optimize the layout of the intake nipple and the air conditioner compressor, most merely make adjustments to the position or configuration of the individual components, failing to address the spatial arrangement issues from an overall integration perspective. For example, some schemes have been proposed to reduce the number of brackets, but the efficiency of air intake and the reliability of installation cannot be effectively balanced due to lack of cooperative design of the air intake connection pipe and the air conditioner compressor installation structure, so that the air intake performance of the engine or the operation stability of the air conditioner compressor is affected. Therefore, a new structural design is needed to solve the problems of low space utilization rate, complex structure, high vibration noise and the like in the installation process of the air inlet connecting pipe of the engine and the air conditioner compressor. The foregoing background is only for the purpose of facilitating an understanding of the principles and concepts of the utility model and is not necessarily in the prior art to the present application and is not intended to be used as an admission that such background is not entitled to antedate such novelty and creativity by virtue of prior utility model or that it is already disclosed at the date of filing of this application. Disclosure of utility model The utility model aims to provide an engine with an air inlet connecting pipe integrated air conditioner compressor mounting structure, which solves the technical problems of low space utilization rate, complex structure, large vibration noise and the like in the mounting process of an engine air inlet connecting pipe and an air conditioner compressor in the prior art.
