[0033] The structure provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0034] refer to Figures 1 to 5 As shown, this embodiment specifically discloses a lightweight intelligent power unit, including:

[0035] The cabin 1 includes a bottom frame 11, on which a left side plate 12, a right side plate 13, a front side plate (not shown), a rear side plate 17, and a top plate 14 are provided; that is, the bottom frame 11, the left side plate 12, the right side plate 13, the front side plate (not shown), the rear side plate 17, and the top plate 14 together form a cabin 1, wherein the top plate 14 is located on the upper part of the left side plate 12, the right side plate 13, the front side plate, and the rear side plate 17. In this embodiment, the left side plate 12, the right side plate 13, the front side plate, the rear side plate 17, and the top plate 14 are made of carbon fiber, which has the characteristics of high structural strength and light weight. Compared with traditional steel plate materials or rectangular tube welded structures, it can effectively reduce the overall weight of the cabin 1.

[0036] The bracket 2 is L-shaped and has two parts, each including a horizontal part 21 and a vertical part 22. The vertical part 22 is connected to the rear side plate 17 of the cabin 1, and has multiple mounting holes 221. Specifically, in the illustrated embodiment, the vertical part 22 includes a connecting plate 222 and a protrusion 223 formed in the middle of the connecting plate 222. The protrusion 223 is embedded in the rear side plate 17 and connected to it. The mounting holes 221 are formed on the connecting plate 222 on both sides of the protrusion 223 and are used to connect to the vehicle chassis, so that the entire cabin can be suspended and mounted on the vehicle chassis. The entire bracket 2 is made of aluminum, which can be directly processed from aviation aluminum blocks. Compared with traditional steel materials, it can also reduce the weight by about 2 / 3.

[0037] Combination Figure 3 As shown, in this embodiment, the bottom frame 11 includes a rectangular frame 111, and two horizontal parts 21 are connected parallel to each other within the rectangular frame 111. Multiple connecting beams 112 are provided between the two horizontal parts 21 and between the horizontal parts 21 and the rectangular frame 111. The multiple connecting beams 112, the two horizontal parts 21 and the rectangular frame 111 together form the bottom frame 11.

[0038] The power assembly 3 is installed on the bottom frame 11 inside the cabin 1. The power assembly 3 includes an engine 31, a generator 32, and a fuel tank 33. A power module 34 is also installed inside the cabin 1. The output end of the engine 31 is connected to the generator 32, the fuel tank 33 is connected to the engine 31 pipeline, and the output end of the generator 32 is connected to the power module 34.

[0039] Among them, the engine 31 can be a high-speed V-type engine, which improves the power-to-weight ratio and reduces the weight by 1 / 3 at the same power; the generator 32 is an integrated motor that combines control and intelligent power unit controller, which reduces both weight and volume; the power module 34 is a dual AC / DC power module that improves integration while also achieving lightweighting.

[0040] In this embodiment, by optimizing the structure of the cabin 1, the rectangular frame 111, the connecting beam 112 and the horizontal part 21 of the bracket are connected as a whole to form the bottom frame 11 of the cabin 1, making the structure of the entire power unit more compact and reasonable. While achieving overall lightweighting, it can also help the heat dissipation of the entire power unit. That is, the lightweight intelligent power unit provided in this embodiment has a high degree of integration, is lightweight, and its structural strength can meet the requirements of vehicle use.

[0041] Continue to combine Figure 1As shown, in some embodiments, the engine 31 is positioned near the left side panel 12, the fuel tank 33 is positioned near the right side panel 13, and the generator 32 is positioned between the engine 31 and the fuel tank 33. This arrangement improves space utilization, makes the entire power system layout compact, and allows for the rational placement of components within a limited space, effectively utilizing the cabin space and avoiding space waste. It also facilitates the integration of other components. Furthermore, separating the engine and fuel tank on opposite sides reduces the impact of the engine on the fuel tank (the engine generates a large amount of heat during operation, and maintaining a certain distance from the fuel tank prevents the fuel tank from being baked by high temperatures, reducing fuel evaporation losses and safety hazards caused by high temperatures).

[0042] Continue to refer to Figure 4 As shown, in some embodiments, the fuel tank 33 is an integrally welded structure with an irregular shape, which can ensure its structural strength and sealing. The upper end of the fuel tank 33 has a sloping surface 331 that is inclined towards the generator 32, which improves the heat dissipation effect inside the cabin and can also fit better with the internal space of the cabin. The bottom of the fuel tank 33 has an embedded part 332. A fuel tank mounting groove 15 is formed between the horizontal part 21 near the right side plate 13 and the right side plate 13, and the embedded part 332 is engaged in the fuel tank mounting groove 15. By setting the fuel tank mounting groove 15 and the corresponding embedded part 332, the fuel tank 33 can be fixed without setting a separate mounting bracket, which further reduces the weight of the entire power unit.

[0043] In some preferred embodiments, a fixing member 333 is provided on the top of the fuel tank 33, and a limiting member 16 corresponding to the fixing member 333 is provided on the inner side wall of the right side plate 13; this further limits and fixes the fuel tank 33, improving the installation stability of the fuel tank 33.

[0044] Continue to refer to Figure 1 As shown, a heat dissipation assembly 4 is also provided on the upper part of the cabin 1. The heat dissipation assembly 4 is used to dissipate heat and cool down the engine 31 and generator 32 inside the cabin 1.

[0045] Optionally, the heat dissipation component 4 includes components such as a cooling fan, a cooling water tank, a heat exchanger, pipes, and a water pump, which are used to cool the interior of the cabin 1 to prevent overheating and affect the stable operation of the power components.

[0046] In some embodiments, a noise reduction component 5 is also provided on the outside of the left side plate 12. During operation, the engine 31 and generator 32 in the power assembly 3 inside the cabin usually generate a lot of noise. By providing the noise reduction component 5, the noise can be effectively absorbed and weakened, reducing noise interference.

[0047] In the illustrated embodiment, the top plate 14 is also equipped with a filter 6 and an air compressor 7, which are used to provide filtered air to the engine 31, reduce the entry of dust, impurities and other particulate matter in the air into the engine cylinder, thereby extending its service life and ensuring its stable performance.
