Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing technology, and in particular to an engine with an integrated air conditioning compressor mounting structure for an intake manifold. Background Technology

[0002] In existing technologies, the engine intake manifold and air conditioning compressor are typically installed separately. Traditionally, the engine intake manifold is located on the side of the engine and connected to the engine block or chassis via a separate bracket. Similarly, the air conditioning compressor is also secured with a separate bracket. This separate installation method has several drawbacks. First, multiple independent brackets occupy a significant amount of engine compartment space, leading to a compact engine compartment layout, increased risk of interference between components, and hindering subsequent maintenance and repair. Second, the independent bracket structure increases the overall weight, raising material costs and negatively impacting fuel economy. Furthermore, vibrations generated by the engine and air conditioning compressor during operation are transmitted through their respective brackets, easily causing resonance and resulting in significant noise, thus reducing the driving experience.

[0003] With the development of the automotive industry, the requirements for engine compartment space utilization and overall performance are constantly increasing, and traditional separate installation structures can no longer meet the needs. Although some technologies attempt to optimize the layout of the intake manifold and air conditioning compressor, most only adjust the position or structure of a single component, failing to solve the space arrangement problem from the perspective of overall integration. For example, some solutions change the position of the intake manifold but do not fully consider its compatibility with the air conditioning compressor installation structure, resulting in insufficient installation stability of the air conditioning compressor; other solutions attempt to reduce the number of brackets, but due to the lack of coordinated design of the intake manifold and air conditioning compressor installation structure, they cannot effectively balance intake efficiency and installation reliability, thus affecting the intake performance of the engine or the working stability of the air conditioning compressor. Therefore, a new structural design is urgently needed to solve the problems of low space utilization, structural complexity, and high vibration and noise during the installation of the engine intake manifold and air conditioning compressor.

[0004] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0005] The purpose of this utility model is to propose an engine with an integrated air conditioning compressor installation structure for the intake pipe, so as to solve the technical problems of low space utilization, complex structure, and high vibration and noise in the installation process of the engine intake pipe and air conditioning compressor in the above-mentioned prior art.

[0006] Therefore, this utility model proposes an engine with an integrated air conditioning compressor mounting structure for the intake manifold.

[0007] Preferably, the present invention may also have the following technical features:

[0008] An engine with an integrated air conditioning compressor mounting structure for an intake manifold includes an intake manifold disposed at the front end of the engine cylinder head; and an air conditioning compressor mounting base integrated into the lower right side of the intake manifold. The air conditioning compressor mounting base includes a first groove, a first mounting post, and a second mounting post. The first groove is open on the right side and recessed towards the right side of the intake manifold. The first mounting post and the second mounting post are hollow and perpendicular to the mounting surface of the intake manifold, and are respectively disposed at the upper and lower ends of the first groove.

[0009] Preferably, the lower part of the air intake pipe is provided with four mounting posts arranged in a square shape, wherein the third mounting post and the fourth mounting post are located on the right side of the air intake pipe, the first mounting post is close to the third mounting post and a first connecting block is provided between them, and the second mounting post is close to the fourth mounting post and a second connecting block is provided between them.

[0010] Preferably, a plurality of lugs are provided on the air conditioning compressor at intervals corresponding to the heights of the first mounting column and the second mounting column.

[0011] Preferably, the air conditioner compressor mounting base and the air intake pipe are integrally formed using a casting process.

[0012] Preferably, a gap is provided between the bottom of the first groove and the right side wall of the air intake pipe.

[0013] Preferably, a heater mounting interface is provided on the front sidewall of the air intake pipe for mounting a heater for preheating.

[0014] Preferably, the system further includes a first pulley system disposed above the engine crankshaft pulley. The first pulley system includes an air conditioning compressor pulley, an alternator pulley, and a fan shaft pulley rotatably disposed at the front end of the engine. The fan shaft pulley is disposed directly above the engine crankshaft pulley, the alternator pulley is disposed to the lower right of the fan shaft pulley and close to the crankshaft pulley, and the air conditioning compressor pulley is disposed to the upper right of the fan shaft pulley. The air conditioning compressor pulley, the alternator pulley, and the fan shaft pulley form a triangular pulley rotation system, which uses two V-belts to transmit power, with the alternator pulley serving as the external tensioner. The crankshaft pulley is connected to the engine crankshaft, the alternator pulley is connected to the alternator, and the air conditioning compressor pulley is connected to the air conditioning compressor disposed on the air conditioning compressor mounting bracket.

[0015] The beneficial effects of this utility model compared with the prior art include:

[0016] 1. The engine of this utility model moves the intake pipe, which was originally located on the side of the cylinder head, to the front end of the cylinder head. An air conditioning compressor mounting bracket for mounting the air conditioning compressor is integrated on the lower right side of the intake pipe. Specifically, two connectors pass through the first mounting post and the second mounting post respectively to fix the air conditioning compressor to the air conditioning compressor mounting bracket. This structural change alters the traditional layout of separate installation of the engine intake pipe and the air conditioning compressor, reduces the use of independent mounting brackets, effectively saves space in the engine compartment, makes the engine compartment layout more compact and reasonable, leaves more space for the arrangement of other components, simplifies the assembly process, shortens the production cycle, and improves manufacturing efficiency.

[0017] 2. The air conditioning compressor mounting bracket on the engine of this utility model is provided with a first groove, which is recessed to the right side of the air intake pipe. The right side opening of the first groove is used to make way for the air conditioning compressor. During installation, there is a certain gap between the side wall of the air conditioning compressor and the first groove, that is, the side wall of the air conditioning compressor does not directly contact the first groove. The hollow design of the first and second mounting columns, while achieving a fixed connection, can also disperse the vibration load generated by the air conditioning compressor during operation through their own structural characteristics. Together with the gap between the first groove and the side wall of the air conditioning compressor, a buffer space is formed, which reduces the direct transmission of vibration to the air intake pipe and the engine body, reduces the probability of resonance caused by vibration superposition, and further optimizes the quietness of the engine during operation.

[0018] 3. A gap is provided between the bottom of the first groove on the engine of this utility model and the right side wall of the intake pipe. This avoids excessive wall thickness during casting, reduces defects such as shrinkage cavities and porosity caused by excessive local metal accumulation during the casting process, and improves the overall quality and mechanical properties of the casting. In addition, this gap can also act as a buffer area during operation. When the intake pipe expands and contracts due to temperature changes, it provides a certain deformation space to prevent damage such as cracking of the mounting base or the intake pipe itself due to stress concentration, thus extending the service life of the components.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0025] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0026] An engine with an integrated air conditioning compressor mounting structure for the intake manifold, such as Figures 1-4As shown, it includes: an intake pipe 01, which is disposed at the front end of the cylinder head 10 of the engine; and an air conditioning compressor mounting base 02, which is integrated into the lower right side of the intake pipe 01. The air conditioning compressor mounting base 02 includes a first groove 201, a first mounting post 202, and a second mounting post 203. The first groove 201 is open on the right side and recessed towards the right side of the intake pipe 01. The first mounting post 202 and the second mounting post 203 are hollow and are disposed perpendicular to the mounting surface A of the intake pipe 01. The first mounting post 202 and the second mounting post 203 are respectively disposed at the upper and lower ends of the first groove 201.

[0027] The aforementioned engine moves the intake manifold 01, originally located on the side of the cylinder head 10, to the front end of the cylinder head 10. An air conditioning compressor mounting bracket 02 for mounting the air conditioning compressor 03 is integrated on the lower right side of the intake manifold 01. A first mounting post 202 and a second mounting post 203 are provided on the air conditioning compressor mounting bracket 02. Specifically, two connectors can pass through the first mounting post 202 and the second mounting post 203 respectively to fix the air conditioning compressor 03 to the air conditioning compressor mounting bracket 02. This structure changes the traditional layout where the engine intake manifold 01 and air conditioning compressor 03 are installed separately, reducing the use of independent mounting brackets, effectively saving space in the engine compartment, making the engine compartment layout more compact and reasonable, leaving more space for the arrangement of other components, simplifying the assembly process, shortening the production cycle, and improving manufacturing efficiency. A first groove 201 is provided on the air conditioning compressor mounting base 02, and the first groove 201 is recessed to the right side of the air intake pipe 01. The right side opening of the first groove 201 is used to make way for the air conditioning compressor 03. During installation, there is a certain gap between the side wall of the air conditioning compressor 03 and the first groove 201. That is to say, the side wall of the air conditioning compressor 03 does not directly contact the first groove 201. The hollow design of the first mounting post 202 and the second mounting post 203, while achieving a fixed connection, can also disperse the vibration load generated by the air conditioning compressor 03 during operation through their own structural characteristics. Together with the gap between the first groove 201 and the side wall of the air conditioning compressor 03, a buffer space is formed, reducing the direct transmission of vibration to the air intake pipe 01 and the engine body, reducing the probability of resonance caused by vibration superposition, and further optimizing the quietness of the engine during operation.

[0028] In some examples of this embodiment, such as Figure 1As shown, the lower part of the intake pipe 01 has four mounting posts arranged in a square shape. The third mounting post 101 and the fourth mounting post 102 are located on the right side of the intake pipe 01. The first mounting post 202 is close to the third mounting post 101, and a first connecting block 204 is arranged between them. The second mounting post 203 is close to the fourth mounting post 102, and a second connecting block 205 is arranged between them. Specifically, the intake pipe 01 can be fixedly installed to the front end of the cylinder head 10 by passing a connector through the four mounting posts on the intake pipe 01. The first connecting block 204 connects the first mounting post 202 and the third mounting post 101, and the second connecting block 205 connects the second mounting post 203 and the fourth mounting post 102, so that the originally relatively independent mounting posts form a whole structure that works together to bear the force. When the air conditioning compressor 03 vibrates during operation or the vehicle encounters bumps while driving, the local force can be distributed to multiple mounting posts, avoiding deformation or damage to a single mounting post due to concentrated force. This effectively improves the load-bearing capacity and long-term reliability of the air intake pipe 01 and the air conditioning compressor mounting seat 02.

[0029] Specifically, such as Figure 2 As shown, corresponding to the height of the first mounting post 202 and the second mounting post 203, a plurality of lugs 301 are provided at intervals on the air conditioning compressor 03. Specifically, lugs 301 can be provided on both the side of the air conditioning compressor 03 near the mounting surface A of the air intake pipe 01 and the side of the mounting surface A away from the air intake pipe 01. During installation, the lugs 301 on both sides of the air conditioning compressor 03 are positioned so that the first mounting post 202 and the second mounting post 203 are precisely locked in the middle of the lugs 301. Then, a connector is used to pass through the first mounting post 202 and the lugs 301 on both sides. Similarly, a connector is used to pass through the second mounting post 203 and the lugs 301 on both sides. With the help of nuts, the air conditioning compressor 03 can be fixedly mounted on the air conditioning compressor mounting base 02. The aforementioned structure, by providing lugs 301 on both sides of the first mounting post 202 and the second mounting post 203, and using connectors passing through the mounting posts to engage with the corresponding lugs 301 and securing them with nuts, forms a bidirectional clamping fastening structure, significantly improving the stability of the air conditioning compressor 03 and the air conditioning compressor mounting base 02. Compared to a single-sided fixing method, the symmetrical layout of the lugs 301 on both sides allows for a more balanced clamping force, preventing the air conditioning compressor 03 from loosening or shifting on one side during operational vibrations or vehicle bumps, ensuring the consistency of its installation posture, and providing a reliable guarantee for the stable operation of the air conditioning compressor 03.

[0030] In some examples of this embodiment, the air conditioner compressor mounting base 02 and the air intake pipe 01 are integrally formed using a casting process. Compared to traditional splicing or welding methods, this integrally formed structure reduces processing steps and assembly stages, improving production efficiency and enhancing overall structural strength. It avoids the risk of structural damage due to insufficient strength at the connection points and ensures precise control of the dimensional accuracy and geometric tolerances of the connection points. This avoids assembly errors and welding deformation that may occur in traditional splicing or welding processes, thus ensuring a high degree of matching between the installation reference of the air conditioner compressor mounting base 02 and the structural parameters of the air intake pipe 01, providing a precise positioning basis for the stable installation of the air conditioner compressor 03. Specifically, as... Figure 3 As shown, a gap is provided between the bottom of the first groove 201 and the right side wall of the air intake pipe 01. This prevents the wall thickness from being too thick during casting, reducing defects such as shrinkage cavities and porosity caused by excessive local metal accumulation during the casting process, and improving the overall quality and mechanical properties of the casting. Furthermore, this gap can also act as a buffer zone during operation, providing a certain deformation space when the air intake pipe 01 expands and contracts due to temperature changes. This prevents stress concentration from causing cracks or other damage to the air conditioning compressor mounting base 02 or the air intake pipe 01 itself, thus extending the service life of the components.

[0031] like Figure 1 As shown, the engine also includes a first pulley system located above the engine crankshaft pulley 04. The first pulley system includes an air conditioning compressor pulley 05, an alternator pulley 06, and a fan shaft pulley 07 rotatably mounted at the front end of the engine. The fan shaft pulley 07 is located directly above the engine crankshaft pulley 04. The alternator pulley 06 is located to the lower right of the fan shaft pulley 07 and close to the crankshaft pulley 04. The air conditioning compressor pulley 05 is located to the upper right of the fan shaft pulley 07. The air conditioning compressor pulley 05, alternator pulley 06, and fan shaft pulley 07 form a triangular pulley rotation system, which uses two V-belts 08 to transmit power, with the alternator pulley 06 acting as the external tensioner. The crankshaft pulley 04 is connected to the engine crankshaft, the alternator pulley 06 is connected to the alternator 09, and the air conditioning compressor pulley 05 is connected to the air conditioning compressor 03 mounted on the air conditioning compressor mounting base 02.

[0032] In some examples of this embodiment, a heater mounting interface 103 is provided on the front sidewall of the intake manifold 01 for mounting a heater for preheating. In cold environments, excessively low engine intake temperatures can affect fuel atomization and combustion efficiency, leading to problems such as difficulty starting and increased emissions. By providing a heater mounting interface 103 on the intake manifold 01, an external electric heater or exhaust waste heat heater can be connected to preheat the intake air, improve combustion conditions, enhance engine low-temperature performance, effectively increase intake air temperature, promote complete fuel atomization and combustion, reduce cold start time, reduce exhaust pollutant emissions, and improve engine power and economy.

[0033] In some examples of this embodiment, such as Figure 2 As shown, an intake manifold cover 11 is installed at the original location of the intake manifold 01 on the side wall of the cylinder head 10, and an engine nameplate is installed on the intake manifold cover 11. The intake manifold cover 11 is used to seal the original intake manifold interface on the cylinder head 10, and the engine nameplate is integrated into the intake manifold cover 11 for easy viewing. By utilizing the interface originally used to connect the intake manifold 01, the intake manifold cover 11 is functionally integrated with the engine nameplate, replacing the traditional method of separately installing the nameplate. This reduces the number of parts on the engine surface, simplifies the overall structure, and lowers production and assembly costs. No additional machining or structural modification of the engine cylinder head 10 is required; the existing intake manifold interface is used directly as the installation base, and the intake manifold cover 11 achieves the sealing function. Compared with traditional solutions, no additional mold development or process adjustment costs are required, significantly improving production efficiency. Integrating the engine nameplate onto the intake manifold cover 11 makes the nameplate more prominent and concentrated, allowing users to quickly view key information such as the engine model and parameters during routine inspections, maintenance, or repairs, without having to search for the nameplate within the engine's complex surface structure, thus improving the convenience of information retrieval.
