Description

Technical Field

[0001] This invention relates to the field of generator technology, and more specifically to a compact generator set. Background Technology

[0002] In the classic layout of traditional generator sets, core components such as the fuel tank, control panel, inverter, and enclosure are directly fixed to the frame body or the mounting plate provided with the frame. This design not only results in the scattered installation of various components and a lack of integration, but also leads to low utilization of the internal space of the entire unit due to the independent space occupied by each component, failing to achieve a compact layout. Furthermore, since all structures rely on the frame as the sole mounting carrier, the frame needs to be machined with a large number of outward-extending lugs to accommodate the fixing requirements of different components. The dual requirements of a large number of lugs and the concentrated load-bearing of components place higher demands on the structural strength of the frame, forcing the frame to use larger-sized materials or more complex processing techniques. Ultimately, this directly increases the costs of materials, processing, and assembly, while also limiting the application flexibility of the product in miniaturized and lightweight scenarios. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a compact generator set that improves space utilization while reducing rack costs.

[0004] The technical solution adopted in this invention is as follows: it includes a frame and an engine mounted on the frame, and also includes an inverter, a fuel tank, and an integrated mounting bracket. The integrated mounting bracket is mounted on the engine and is located between the engine, the fuel tank, and the inverter, and is used to mount the fuel tank and the inverter. The fuel tank is located above the engine; the inverter is located below the fuel tank, with its upper end mounted on the integrated mounting bracket and its lower end mounted on the outside of the engine housing.

[0005] The principle of the technical solution: The integrated mounting bracket is installed on the engine and used to install the fuel tank and the inverter, allowing them to be installed close to the engine. This effectively utilizes the space around the engine, connecting the engine, fuel tank, and inverter into a single unit. Compared to installing them separately on the rack, this significantly saves installation space (when using the rack as the core of the installation, the structures are not regular shapes, and to avoid conflicts and interference, they are usually arranged in a more dispersed manner, resulting in low space utilization). Furthermore, when traditionally the structures are installed on the rack, because the rack is located on the outside of each structure, it is necessary to install lugs at multiple locations around the perimeter. In contrast, the integrated mounting bracket in this application is located between the fuel tank, the inverter, and the engine, i.e., within the space of each structure. On the inside, only one or two fixed connection points are needed. Therefore, after the integrated mounting bracket is set in this application, a large number of mounting lugs or mounting plates set on the frame can be omitted, and the installation steps are simplified. In addition, after the various structures are not installed on the frame, the strength requirements and size requirements of the frame are reduced, thereby reducing costs. The inverter is located below the fuel tank. The upper and lower ends of the inverter are respectively installed on the integrated mounting bracket and the outside of the engine housing. This not only eliminates the traditional inverter mounting bracket, but also supports the integrated mounting bracket through the inverter, thereby supporting the fuel tank. The inverter itself has an aluminum alloy frame, heat sink, etc., which has a certain strength and can effectively share some of the pressure.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention eliminates the traditional installation method with the frame as the core, and instead uses the engine as the core to install other structures, effectively utilizing the space around the engine, making the overall volume more compact and greatly improving the space utilization rate.

[0007] 2. This invention utilizes an integrated mounting rack to replace the traditional structure of multiple mounting lugs and mounting plates, while reducing the material requirements of the rack, thereby lowering the overall cost and achieving cost savings.

[0008] 3. The oil tank, inverter and other structures of the present invention only require 1 to 2 connection points for installation and fixation. Compared with traditional oil tanks and inverters that require multiple mounting lugs or mounting plates, the present invention is simpler to install and faster to install.

[0009] 4. The structural design of this invention also utilizes the inverter to support the integrated mounting bracket, increasing the load-bearing capacity of the integrated mounting bracket and sharing part of the weight of the oil tank, effectively ensuring the overall strength and stability.

[0010] In a preferred embodiment of the present invention, the integrated mounting bracket includes a first mounting part, a second mounting part, and a third mounting part connected in sequence. The first mounting part is used to mount the engine; the second mounting part is used to mount the inverter; and the third mounting part is used to support the fuel tank.

[0011] Beneficial effects: The first mounting part, the second mounting part, and the third mounting part respectively connect the engine, the fuel tank, and the inverter.

[0012] In a preferred embodiment of the present invention, the first mounting part includes an inclined section and a horizontal connecting section. The inclined section is used to be mounted on the inclined surface of the engine housing, and the horizontal connecting section is used to connect the inclined section and the second mounting part, so that the second mounting part is located outside the engine housing.

[0013] Beneficial effects: The inclined section is used to fit the housing of the engine, and the horizontal connecting section is used to allow the second mounting part to be located outside the housing of the engine, which facilitates the installation of the vertically arranged inverter; and makes the layout more reasonable and compact.

[0014] In a preferred embodiment of the present invention, a vertical support is connected above the inclined section, and the vertical support is used to connect to the side of the oil tank.

[0015] Beneficial effects: The vertical support lug is used to connect to the side of the oil tank, which can further restrict the oil tank from the side. When used in conjunction with the third mounting part below the oil tank, the position of the oil tank is fixed and its stability is improved.

[0016] In a preferred embodiment of the present invention, an ignition coil is provided on the inner side of the integrated mounting bracket.

[0017] Beneficial effects: The integrated mounting bracket is located between the engine, the fuel tank and the inverter, and the ignition coil is installed inside the integrated mounting bracket, which can further utilize the space between the three components and improve space utilization.

[0018] In a preferred embodiment of the present invention, a cooling fan is provided on one side of the engine, and the side where the inverter is located and the side where the cooling fan is located are two adjacent sides of the engine, and the airflow blown out by the cooling fan passes through the inverter.

[0019] Beneficial effects: The inverter surface refers to the surface with the largest area of ​​the inverter; the cooling fan surface refers to the rotating plane of the cooling fan impeller; since the inverter surface and the cooling fan surface are two adjacent sides of the engine, that is, the inverter is located behind the cooling fan impeller, the airflow blown out after it starts can directly blow onto the inverter, realizing heat dissipation of the inverter. Not only can heat dissipation be effective, but the airflow direction is not obstructed too much, and the heat dissipation efficiency is higher (traditional methods often open holes at the top of the fan guide shroud, and some airflow overflows for heat dissipation. After heat dissipation, it is easily accumulated inside the generator due to the influence of the inverter and other structures).

[0020] In a preferred embodiment of the present invention, the inverter is provided with a plurality of heat dissipation fins, and the airflow blown out by the cooling fan flows along the length direction of the heat dissipation fins.

[0021] Beneficial effects: The airflow flows along the length of the heat dissipation fins, that is, through the channels between the multiple heat dissipation fins, which not only removes the heat from the heat dissipation fins and improves the heat dissipation efficiency of the inverter, but also avoids obstructing the airflow and reducing the flow velocity, thus affecting heat dissipation.

[0022] In a preferred embodiment of the present invention, the engine and the cooling fan are provided with a connecting shell, the connecting shell having an air outlet, the position of which corresponds to the inverter; one side of the connecting shell is fixedly connected to the outer cover of the cooling fan, and the other side is fixedly connected to the housing of the engine; the connecting shell covers the outside of the engine.

[0023] Beneficial effects: The air outlet is a reserved channel, allowing the airflow blown by the cooling fan to directly act on the inverter; the connecting shell is used to connect the engine and the cooling fan, making them integrated and further improving space utilization; the connecting shell wraps around the outside of the engine, forming a "[" shape, with its lower end supporting the engine to make the connection between the two more stable, and its upper end sharing the installation position with the integrated mounting bracket and providing support for it.

[0024] In a preferred embodiment of the present invention, at least two shock absorbers are connected below both the engine and the cooling fan, and the shock absorbers are fixedly connected to the frame.

[0025] Beneficial effects: The shock absorber is provided below both the engine and the cooling fan. The shock absorber is installed on the frame, which can provide effective shock absorption and make the whole structure stable.

[0026] In a preferred embodiment of the present invention, the frame extends upward and surrounds the outside of the oil tank.

[0027] Beneficial effects: The frame extends upward and surrounds the outside of the oil tank, which can be easily lifted and moved, and can also protect the oil tank and improve its anti-collision capability. Attached Figure Description

Detailed Implementation

[0036] Typical embodiments embodying the features and advantages of the present invention will be specifically described in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0037] In the description of this application, the terms "first," "second," "side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] As attached Figure 1 and Figure 2 As shown, the present invention provides a compact generator set: including a frame 1 and an engine 2 mounted on the frame 1. The cylinder block of the engine 2 is located at the upper end and is inclined. An integrated mounting bracket 5 is mounted on the upper inclined surface of the cylinder block. An oil tank 4 is located above the integrated mounting bracket 5, and an inverter 3 is located on the side. The integrated mounting bracket 5 is located between the engine 2, the oil tank 4, and the inverter 3, and is used to mount the oil tank 4 and the inverter 3. The oil tank 4 and the inverter 3 are mounted to the engine 2 through the integrated mounting bracket 5, close to the engine 2, effectively utilizing the engine 2. The integrated mounting bracket 5, located between the fuel tank 4, the inverter 3, and the engine 2 (i.e., on the inner side of each structure), reduces the need for mounting lugs and simplifies the installation process. Furthermore, by eliminating the structure from the mounting bracket 1, the strength and dimensional requirements of the bracket 1 are reduced, thus lowering costs.

[0040] As attached Figures 3-6 As shown, in this embodiment, the integrated mounting bracket 5 includes a first mounting part 51, a second mounting part 52, and a third mounting part 53 connected in sequence. The first mounting part 51 is used to be mounted on the engine 2 and includes an inclined section 511 and a horizontal connecting section 512. The inclined section 511 is used to be mounted on the inclined surface of the cylinder head housing of the engine 2, and the horizontal connecting section 512 is used to connect the inclined section 511 and the second mounting part 52, so that the second mounting part 52 is located outside the housing of the engine 2, thereby facilitating the installation of the vertically arranged inverter 3.

[0041] Furthermore, the integrated mounting bracket 5 is not limited to the above structure. Its horizontal connecting section 512 can be set at an inclination, or it can be set above or below the inclination section 511 and the second mounting part 52. The third mounting part 53 can be set on both sides of the second mounting part 52. Alternatively, it can be any other structure that can connect and install the oil tank 4 and the inverter 3 onto the engine 2.

[0042] As attached Figure 4 and Figure 5As shown, in this embodiment, a vertical support lug 54 is connected above the inclined section 511. The vertical support lug 54 is used to connect to the side of the oil tank 4 and can restrict the oil tank 4 from the side. The third mounting part 53 can be horizontal and is used to support the oil tank 4. The two are used together to effectively support and fix the oil tank 4.

[0043] As attached Figure 3 and Figure 5 As shown, in this embodiment, the second mounting part 52 can be vertical and used to install the inverter 3. In this embodiment, the integrated mounting bracket 5 is provided with multiple through holes, which are connected to other structures by bolts, or by means of buckles, pins, etc. In addition, the integrated mounting bracket 5 is integrally molded and can be directly cast or extruded. Compared with the traditional method of setting multiple lugs on the frame, it is cheaper and easier to install.

[0044] As attached Figure 2 and Figure 3 As shown, in this embodiment, the fuel tank 4 is located above the engine 2 and extends partially to the outside of the engine 2; the inverter 3 can be arranged vertically and is located below the portion of the fuel tank 4 that extends to the outside of the engine 2. The upper end of the inverter 3 is mounted on the integrated mounting bracket 5, and the lower end is mounted on the outside of the casing of the engine 2. This eliminates the need for a traditional mounting bracket for the inverter 3, while still supporting the integrated mounting bracket 5 through the inverter 3, thereby supporting the fuel tank 4. The inverter 3 itself has an aluminum alloy frame, heat sink, etc., which provides a certain strength and can effectively share some of the pressure.

[0045] As attached Figure 4 As shown, in this embodiment, an ignition coil 6 is provided on the inner side of the integrated mounting bracket 5. The ignition coil 6 can be installed on the inclined section 511 by bolts, that is, it is set between the inclined section 511, the second mounting part 52 and the horizontal connecting section 512, which can further utilize the space between the three and improve the space utilization rate.

[0046] As attached Figure 3As shown, in this embodiment, a cooling fan 7 is provided on one side of the engine 2. The engine 2 and the cooling fan 7 are provided with a connecting shell 9. One side of the connecting shell 9 is fixedly connected to the outer cover of the cooling fan 7, and the other side is fixedly connected to the housing of the engine 2. The connecting shell 9 covers the outside of the engine 2. At least two shock absorber frames 11 are connected to the bottom of both the engine 2 and the cooling fan 7. The shock absorber frames 11 are fixedly connected to the frame 1. The connecting shell 9 is used to connect the engine 2 and the cooling fan 7, so that the two are integrated into one, further improving the space utilization. The shock absorber frames 11 are provided below both. By using the shock absorber frames 11 to install on the frame 1, effective shock absorption can be provided, and the overall stability can be improved. The connecting shell 9 covers the outside of the engine 2, forming a "[" shape. Its lower end can support the engine 2, making the connection between the two more stable. Its upper end can share the installation position with the integrated mounting bracket 5 and form support for it.

[0047] As attached Figure 3 and Figure 7 As shown, in this embodiment, the side where the inverter 3 is located and the side where the cooling fan 7 is located are two adjacent sides of the engine 2. The connecting shell 9 has an air outlet 10, and the position of the air outlet 10 corresponds to that of the inverter 3. The airflow blown out by the cooling fan 7 passes through the air outlet 10 and blows directly onto the inverter 3. The inverter 3 is provided with multiple heat dissipation fins 8, which are arranged vertically. The airflow blown out by the cooling fan 7 flows along the length of the heat dissipation fins 8, that is, it flows through the channel between the multiple heat dissipation fins 8, which not only removes the heat on the heat dissipation fins 8 and improves the heat dissipation efficiency of the inverter 3, but also avoids obstructing the airflow and reducing the flow velocity, thus affecting heat dissipation.

[0048] As attached Figure 1 As shown, in this embodiment, the frame 1 extends upward and surrounds the outside of the oil tank 4, which facilitates lifting and transfer, and also protects the oil tank 4, improving its anti-collision capability.

[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
