[0038] As Figures 1-7 shown, this embodiment provides a generator set, including a box body, an engine 40, an air filter 50 and electronic components.

[0039] The box body includes a base 11, side plates, a support plate 13 and a top plate 14. The side plates include a front side plate, a left side plate, a right side plate 12 and a rear side plate. Among them, the front side plate, the left side plate and the rear side plate are not shown in the drawings. A support plate 13 is respectively arranged at the four corners of the box body. A partition plate 20 is arranged inside the box body. The partition plate 20 divides the cavity surrounded by the front side plate, the left side plate, the right side plate 12 and the rear side plate into an electrical cavity 15 and a cooling cavity 16. The partition plate 20 is provided with a through first opening 21 and a second opening 22. The first opening 21 and the second opening 22 are located in the middle area of the partition plate 20 along the horizontal direction. An air inlet 121 is opened on the base 11 and / or the side plates of the box body. The side plates can be one or more of the front side plate, the right side plate 12 and the rear side plate. The air inlet 121 is communicated with the electrical cavity 15, and the air for cooling the engine 40 enters the box body through the air inlet 121. The top plate 14 is arranged above the electrical cavity 15 and covers the electrical cavity 15. The top plate 14 is connected to the partition plate 20 and two support plates 13 at the opposite ends (i.e., the front and rear ends) on the right side of the box body. A plurality of mounting holes are arranged on the top plate 14, and components such as a controller 61 and an air circuit breaker assembly 62 are installed in the mounting holes.

[0040] The engine 40 is installed on the base 11 of the box body and is located in the cooling cavity 16 inside the box body. A cooling fan 41 is arranged on the side of the engine 40 close to the partition plate 20, and the cooling fan 41 is arranged opposite to the first opening 21.

[0041] The air filter 50 is also arranged in the cooling cavity 16 and is also located above the engine 40. A linear intake pipe 51 is arranged on the side of the air filter 50 close to the partition plate 20. One end of the intake pipe 51 is communicated with the second opening 22, and the second opening 22 is located above the first opening 21.

[0042] Electronic components are arranged in the electrical cavity 15 of the box body. In addition to the controller 61 and the air circuit breaker assembly 62 installed on the top plate 14 mentioned above, the electronic components also include an automatic voltage regulator 63 (i.e., AVR), a battery 64 and a charger 65 for charging the battery 64.

[0043] In this embodiment, the air filter 50 is disposed in the cooling chamber 16, and a second opening 22 for air circulation is formed in the partition plate 20. When the engine 40 operates, part of the air entering the electrical chamber 15 through the air inlet 121 on the base 11 and / or the side plate of the box body flows to the outer surface of the engine 40 through the first opening 21 and cools the engine 40, and the other part flows into the air filter 50 through the second opening 22 and finally enters the combustion chamber of the engine 40. Therefore, the intake pipe 51 of the air filter 50 can be configured to be linear, which can reduce the manufacturing cost of the intake pipe 51 and thus reduce the overall cost of the generating set. In addition, when the external air flows through the electrical chamber 15, it can also have a certain cooling effect on the electronic components in the electrical chamber 15.

[0044] In one embodiment, as Figure 1 , 5 and FIG. 6 show, the longitudinal cross-sectional shape of the intake pipe 51 is flat, for example, it can be oval or kidney-shaped. By flattening the intake pipe 51, the size of the air filter in the vertical direction can be reduced, and thus the size of the entire generating set in the vertical direction can also be appropriately reduced.

[0045] In one embodiment, as Figure 1 , 5 and FIG. 6 show, an elastic seal 23 is disposed on one side of the partition plate 20. The elastic seal 23 is located in the cooling chamber 16 and is disposed around the second opening 22. A jack adapted to the second opening 22 is formed in the elastic seal 23, and the material of the elastic seal 23 can be sponge or synthetic rubber. One end of the intake pipe 51 is inserted into the jack. While achieving the connection between the intake pipe 51 and the second opening 22, it is not necessary to connect the intake pipe 51 to the partition plate 20, which facilitates the disassembly and assembly of the intake pipe 51. The elastic seal 23 surrounds the above-mentioned end of the intake pipe 51, which can prevent or reduce the air from flowing outside the intake pipe 51. The elastic seal 23 can also reduce the possibility of the water flowing downward from the top plate 14 flowing into the electrical chamber 15 through the second opening 22.

[0046] In one embodiment, as Figure 4 and 6 show, a mounting plate 30 located in the electrical chamber 15 is disposed on the other side of the partition plate 20. The mounting plate 30 is fixedly connected to the partition plate 20. The automatic voltage regulator 63 and the charger 65 are mounted on the mounting plate 30. The battery 64 is disposed on the base 11 of the box body and is located below the automatic voltage regulator 63 and the charger 65. Since the front side plate, the right side plate 12 and the rear side plate are usually detachable for facilitating the maintenance and repair of the generating set, the above installation and layout of the automatic voltage regulator 63, the charger 65 and the battery 64 are reasonable.

[0047] In one embodiment, as Figure 4 and 6 shown, the mounting plate 30 includes a main body portion 31 parallel to the partition plate 20 and connecting portions 32 extending from both ends of the main body portion 31 towards the partition plate 20 and connected to the partition plate 20. The automatic voltage regulator 63 and the charger 65 are fixed to the main body portion 31 by bolts and are located on the side of the main body portion 31 away from the partition plate 20. A certain space is formed between the main body portion 31 and the partition plate 20 to facilitate the flow of air towards the second opening 22.

[0048] In one embodiment, as Figure 6 shown, an oil cooler 70 is fixedly provided on the other side of the partition plate 20, and the oil cooler 70 faces the first opening 21. When air flows from the electrical chamber 15 towards the first opening 21, it will flow over the surface of the oil cooler 70, thereby being able to cool the oil in the engine 40.

[0049] In one embodiment, as Figure 6 shown, a collision prevention plate 80 is also fixedly provided on the other side of the partition plate 20. The collision prevention plate 80 is located between the oil cooler 70 and the battery 64, and a certain distance is maintained between the collision prevention plate 80 and the oil cooler 70. The collision prevention plate 80 can be fixed to the base 11 or fixed to the partition plate 20. Since the battery 64 itself has a relatively heavy weight, generally, the battery 64 is directly placed on the base 11 of the box body without being fixed. In some cases of shaking, the battery 64 may collide with the oil cooler 70, resulting in damage to the battery 64 and / or the oil cooler 70. Therefore, by providing the collision prevention plate 80 between the oil cooler 70 and the battery 64, the situation where the battery 64 collides with the oil cooler 70 can be avoided. At the same time, since the distance between the collision prevention plate 80 and the battery 64 is shorter than the distance between the battery 64 and the oil cooler 70, even if the battery 64 hits the collision prevention plate 80, the damage to the battery 64 itself is very small, even negligible.

[0050] In one embodiment, as Figure 6 shown, a buffer pad 81 is provided on the side of the collision prevention plate 80 facing the battery 64. The buffer pad 81 can be made of materials such as sponge, synthetic rubber, and silica gel, and can avoid damage to the battery 64 caused by collision.

[0051] In one embodiment, as Figure 2 and 3As shown, the air inlet 121 is arranged on the side plate of the box body parallel to the partition plate 20, that is, the air inlet 121 is arranged on the right side plate 12. Therefore, the opening range of the air inlet 121 can be designed to be relatively large to meet the air intake requirements of the engine 40. In the area on the inner side of the right side plate 12 facing the air inlet 121, a louvered flow deflector can also be arranged. In addition, a sound insulation sponge 122 is arranged at the upper end of the inner side of the right side plate 12. On the one hand, the sound insulation sponge 122 can reduce the noise generated outward when the engine 40 group works, and on the other hand, it can reduce the water flowing from the right side of the top plate 14 downward into the electrical cavity 15.

[0052] In one embodiment, as Figure 3 shown, a water baffle 123 is also arranged on the inner side of the side plate below the sound insulation sponge 122. The water baffle 123 faces the air inlet 121 and maintains a certain distance from the air inlet 121. Since the battery 64 itself has a certain degree of waterproofness, the water baffle 123 is mainly used to block the water splashed from the outside to the automatic voltage regulator 63 and the charger 65. Therefore, the water baffle 123 is located above the battery 64.

[0053] In the description of the present invention, a large number of specific details are set forth. However, it can be understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
