[0025] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] In the embodiment of the present utility model, Figures 1-4 As shown, the installation structure of the engine 1 and the air compressor 2 includes: an engine 1, an air compressor 2, a mounting assembly and a casing 5; the air compressor 2 is transmission-connected to the engine 1; the mounting assembly includes a first lug portion 3 and a second lug portion 4 respectively provided on both sides of the air compressor 2, one end of the first lug portion 3 is bent to one side to form a bent section 301, and a first mounting point is formed at the other end thereof for connecting to the engine 1, and the second lug portion 4 is provided with a notch 401, the notch 401 is used to avoid the engine 1, and a second mounting point is formed for connecting to the engine 1; the casing 5 covers the air compressor 2, and the first mounting point and / or the second mounting point are exposed outside the casing 5 so that at least one of the two is not in contact with the casing 5.

[0028] Specifically, in the embodiment of the present utility model, the engine 1 and the air compressor 2 are transmission-connected, and both have a housing; a first lug portion 3 and a second lug portion 4 are provided on both sides of the housing of the air compressor 2, and both lug portions can be fixedly connected to the housing of the engine 1. On the one hand, the air compressor 2 can be installed on the engine 1, and on the other hand, a multi-point fixing method can be used to improve the overall stability and reliability of the engine 1, so as to reduce noise from the connection method. Specifically, a first mounting point and a second mounting point are formed on the first lug portion 3 and the second lug portion 4, respectively, and each mounting point is used to fix the corresponding lug portions to the housing of the engine 1. Of course, the positions of the two lug portions can vary according to different models of engines 1; such as Figure 1 、 Figure 2 As shown, the engine 1 is a front-mounted engine 1, and the two lugs are arranged along the gearbox of the engine 1 from the crankcase. In other embodiments, they can also be arranged along another direction, which is not limited here.

[0029] Furthermore, the first lug portion 3 is provided with a bent section 301, which bends toward one side of the first lug portion 3. This not only increases the flexibility of the first lug portion 3, facilitating the connection between the engine 1 and the air compressor 2 components of varying models and sizes, facilitating installation and compensating for manufacturing tolerances or assembly errors, but also alters the force transmission path from the air compressor 2 to the engine 1. By redirecting the force, it disperses or redistributes the vibration and force generated by the operation of the engine 1, thereby reducing the vibration directly transmitted to the air compressor 2 and indirectly reducing noise. Furthermore, the bent section 301 increases the overall rigidity of the first lug portion 3, improving its bending and torsion resistance, thereby enhancing the stability and durability of the entire mounting structure. It also helps avoid interference with other nearby components or structures during installation, ensuring sufficient space for installation and avoiding potential wear issues. Furthermore, the bent section 301 helps to more evenly distribute the load applied to the mounting point, preventing local overload and extending component life.

[0030] In addition, the second lug portion 4 is formed with a notch 401 for avoiding the housing of the engine 1; on the one hand, the space utilization of the structure can be optimized to make the structure more compact; on the other hand, the notch 401 can be used to increase the connection area between the second lug portion 4 and the engine 1, thereby reducing the noise generated by improving the connection stability between the two.

[0031] In the embodiment of the present invention, a shell 5 is provided outside the air compressor 2, and the shell 5 serves the purpose of dust prevention and noise reduction; of course, corresponding sound-absorbing materials can also be laid inside the shell 5 to further achieve the purpose of noise reduction. In addition, the first mounting point and / or the second mounting point are exposed outside the shell 5, so that at least one of them is not in contact with the shell 5, which helps to reduce the vibration transmitted to the shell 5, thereby reducing noise. That is: if the mounting point is not in direct contact with the shell 5, then the vibration generated by the engine 1 and the air compressor 2 will not be directly transmitted to the shell 5. As the shell 5 has a relatively large surface area, any small vibration will be amplified into audible noise; by cutting off the direct vibration transmission path from the internal mechanical components to the shell 5, this amplification effect can be significantly reduced. When the mounting point is separated from the housing 5, it is equivalent to creating an isolation zone between the vibration source (i.e., the engine 1 and the air compressor 2) and the noise carrier that may be amplified (i.e., the housing 5), which is similar to using sound insulation materials or shock absorbers to isolate the vibration transmission between two structural parts; making the housing 5 work as an independent acoustic component rather than participating as part of the vibration can better control the acoustic characteristics of the entire system. In addition, different structures have different natural frequencies. If the mounting point is in direct contact with the housing 5, it may cause resonance between the two, thereby amplifying the noise; by ensuring that at least one mounting point is not in contact with the housing 5, this resonance phenomenon can be avoided. In this embodiment, the first mounting point is located outside the housing 5 and is not in contact with the housing 5 as an example.

[0032] This embodiment ensures that the engine 1 and the air compressor 2 are connected and fixed at multiple points through the first mounting point and the second mounting point, thereby improving the stability and reliability of the two and preventing noise caused by looseness of the two. At the same time, the corresponding mounting points are not in contact with the housing 5, thereby avoiding the housing 5 from being used as a "noise amplifier", which can further reduce noise.

[0033] like Figure 2 、 Figure 4 As shown, in one embodiment, the first mounting points are multiple first mounting holes 302 spaced apart along the same direction on the first lug portion 3. Specifically, to quickly connect and secure the engine 1 and the air compressor 2, this embodiment defines the first mounting points formed on the first lug portion 3 as multiple first mounting holes 302. These multiple first mounting holes 302 are spaced apart along the same direction to provide multiple points of fixation in that direction, thereby improving the stability and reliability of the connection between the two. The provision of the first mounting holes 302 facilitates the insertion of fasteners such as screws into the housings of both the engine 1 and the air compressor 2, making installation convenient and quick.

[0034] like Figure 4 、 Figure 5As shown, in one embodiment, the second mounting point is a plurality of second mounting holes 402 extending through the notch 401. Specifically, to secure the second lug 4 to the engine 1, this embodiment provides a second mounting hole 402 in the notch 401 of the second lug 4. The second mounting hole 402 extends through the notch 401, allowing fasteners such as screws to secure the second lug 4 to the housing of the engine 1 through the second mounting hole 402. This also improves the structural strength and stability of the connection.

[0035] Furthermore, if Figure 4 As shown, in one embodiment, the engine 1 has a connecting protrusion 6 that is configured to extend into the notch 401 and be secured to the second mounting hole 402 by a fastener. Specifically, the housing of the engine 1 is integrally formed with a connecting protrusion 6 that can extend into the notch 401. This connecting protrusion 6 can cooperate with the second lug portion 4 to provide structural reinforcement at this location, and can also facilitate the connection and securing of the two, preventing looseness and noise.

[0036] like Figure 1-Figure 3 As shown, in one embodiment, the engine 1 and the housing 5 are respectively provided with a plurality of first mounting columns 7 and a plurality of second mounting columns 8 in a one-to-one correspondence, and the corresponding first mounting columns 7 and the second mounting columns 8 are fixedly connected. Specifically, in order to fix the housing 5 to the casing of the engine 1; this embodiment provides a plurality of first mounting columns 7 and a plurality of second mounting columns 8 on the opposite end faces of the casing of the engine 1 and the housing 5, respectively, each mounting column corresponding to one another, and two by two are grouped together, and can be screwed through and then locked. Of course, the mounting columns can be arranged at intervals along the circumference of the housing 5, and the use of a multi-point fixing method can also improve the structural stability and reliability of the connection. In addition, the detachable connection method of the housing 5 also facilitates the subsequent maintenance or repair of the corresponding components.

[0037] like Figure 2 As shown, in one embodiment, the engine 1 has a crankshaft, which is provided with a drive wheel. The drive wheel is connected to a driven wheel via a synchronous belt 9, and the driven wheel is connected to the drive shaft of the air compressor 2. In this embodiment, a drive wheel is provided at the end of the crankshaft, and the rotation of the drive wheel is transmitted to the driven wheel by a synchronous belt 9 (belt). The driven wheel is then linked to the operation of the air compressor 2 to achieve a noise reduction function by reducing vibration.

[0038] This embodiment also provides an engine 1 structure, including the above-mentioned mounting structure. The specific structure of the mounting structure refers to the above-mentioned embodiment. Since the present engine 1 structure adopts all the technical solutions of the above-mentioned embodiment, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be repeated here one by one.

[0039] This embodiment also provides a three-wheeled motorcycle, including the engine 1 structure described above. The specific structure of the engine 1 structure refers to the above embodiment. Since this three-wheeled motorcycle adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described one by one here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
