[0046] Example 1

[0047] Traditionally, the cylinder block and generator housing are usually independent components, connected by bolts or gears for power transmission and coordination. However, this traditional structure has the following drawbacks: First, the independent engine housing results in a large overall size, occupying considerable space and hindering installation and layout within the already limited engine compartment. Second, the numerous connecting components not only increase material and manufacturing costs but also reduce the reliability and transmission efficiency of the entire power system. Loosening and wear at the connections can easily lead to frequent malfunctions. Furthermore, the numerous components generate significant vibration and noise during operation, affecting the comfort and lifespan of the equipment. Based on the above technical problems, this application provides a cylinder block integrating a generator housing, which is described below in conjunction with... Figures 1-6 Please describe this structure in detail.

[0048] Combination Figure 1 As shown, the cylinder block integrating the generator housing includes a cylinder body 1 and a fixed housing 2.

[0049] Specifically, the cylinder body 1 is divided into upper and lower parts by the crankshaft centerline 16. The upper part is the upper cylinder body 1 and the lower part is the lower cylinder body 1. The rear end faces of the upper cylinder body 1 and the lower cylinder body 1 are directly formed with a fixed housing 2 adapted to the generator, and the fixed housing 2 is coaxial with the cylinder body 1. The fixed housing 2 shares part of the wall with the cylinder chamber inside the cylinder body 1.

[0050] Combination Figure 1 As shown, the fixed housing 2 is cylindrical, specifically cylindrical, and has an installation chamber 3 inside, which is used to install the engine.

[0051] Specifically, the inner wall of the fixed housing 2 is provided with a limiting member 4, which can limit the engine to the mounting chamber 3.

[0052] In summary, the cylinder body 1 and the fixed housing 2 in this application are integrally formed, meaning that the cylinder body 1 and the fixed housing 2 are integrated together. This eliminates the need for additional components to connect the cylinder body 1 and the fixed housing 2, making the overall structure more compact. Consequently, the volume of the entire device, including the fixed housing 2 and the cylinder body 1, is reduced, minimizing space requirements. This contributes to the miniaturization and lightweight design of automobiles and other equipment, improving vehicle handling performance and fuel economy. It also facilitates installation and layout in the already limited engine compartment. Furthermore, it reduces material and manufacturing costs, improves the reliability and transmission efficiency of the entire power system, and prevents malfunctions caused by loosening or wear at the connection points between the two components. In addition, during operation, vibration and noise are low, which does not affect the comfort and service life of the equipment.

[0053] In addition, compared with the traditional multi-part connection structure, it reduces the number of sealing surfaces, lowers the risk of oil leakage and coolant leakage, and better protects the internal components of the engine and generator from the intrusion of dust, moisture and other impurities, ensuring their normal operation.

[0054] In this embodiment, further, combined with Figure 1 See also Figure 2 As shown, the limiting component 4 for the generator stator includes a limiting protrusion 5 and a limiting groove 6, which are spaced apart along the circumferential direction of the fixed housing 2.

[0055] Specifically, the inner wall of the fixed housing 2 has a limiting protrusion 5 protruding towards the center of the fixed housing 2; the inner wall of the fixed housing 2 has a limiting groove 6 recessed towards the outer wall.

[0056] Furthermore, the limiting protrusion 5 and the limiting slot 6 are designed according to the outer contour and installation requirements of the generator stator to ensure that the stator can be stably installed in the housing cavity. Figure 2 The present invention provides a limiting protrusion 5 and a limiting groove 6 with an elongated structure, both of which extend along the length of the fixed housing 2.

[0057] Preferably, the height of the limiting protrusion 5 is set at 3mm~4mm, the width at 3mm~5mm, and the depth at 30mm~40mm; the depth of the limiting slot 6 is set at 30mm~40mm, the width at 3mm~5mm, and the height at 3mm~4mm.

[0058] Furthermore, the limiting component 4 also includes a damping layer; the surfaces of the limiting protrusion 5 and the limiting groove 6 are covered with a damping layer. Preferably, the damping layer is a damping rubber layer, which can offset, mitigate, and reduce the vibration generated during generator operation, and can reduce the transmission of vibration.

[0059] Preferably, the thickness of the shock-absorbing rubber layer is set at 1.5mm~2mm, the width at 3mm~5mm, and the depth at 30mm~40mm.

[0060] Furthermore, there are multiple limiting members 4; the multiple limiting members 4 are arranged at intervals along the circumferential direction of the fixed housing 2. Preferably, there are three limiting members 4, which are arranged at equal intervals along the circumferential direction of the fixed housing 2 to meet the requirements of the engine stator.

[0061] In this embodiment, the cylinder block integrating the generator housing further includes a reinforcing member 7; the reinforcing member 7 includes a fixing part 8 and an extension part 9 integrally formed with the fixing part 8.

[0062] Specifically, the fixing part 8 is integrally formed on the side wall of the cylinder body 1 facing the fixing housing 2, and the fixing part 8 protrudes from the side wall of the cylinder body 1 facing the fixing housing 2. The fixing part 8 extends along the side wall of the fixing housing 2 to form an extension 9 that can abut against the side wall of the fixing housing 2.

[0063] Furthermore, multiple reinforcing members 7 are provided; the multiple reinforcing members 7 are arranged in a radiating pattern with the axis of the cylinder body 1 as the center.

[0064] Furthermore, combining Figure 1 , and see Figure 5 The lower edge of the fixed housing 2 protrudes beyond the lower edge of the cylinder body 1. Therefore, when the fixed housing 2 is integrally formed onto the cylinder body 1, a baffle 17 is integrally formed on the portion of the fixed housing 2 that extends beyond the cylinder body 1. At this time, the reinforcing member 7 corresponding to the position of the baffle 17 will pass through the baffle 17 and abut against the inner wall of the fixed housing 2.

[0065] It is worth noting that the aforementioned one-piece molding can all be understood as being achieved through molding dies; one-piece casting improves the modal characteristics of the cylinder block and generator housing, thereby improving NVH performance.

[0066] In summary, the reinforcing member 7 connects one end to the cylinder body 1 and the other end to the fixed housing 2, thus improving the connection stability between the cylinder body 1 and the reinforcing member 7, enhancing the mechanical strength of the connection between the cylinder body 1 and the fixed housing 2, and preventing the fixed housing 2 from breaking off from the cylinder body 1 due to the installation of the generator. This makes the connection between the engine and the generator more robust, enabling it to withstand greater mechanical loads and vibrations, improving the reliability and durability of the entire system, and reducing the risk of component loosening or damage under complex operating conditions.

[0067] In addition, the number of parts and assembly steps has been reduced, simplifying the production process, improving production efficiency, and lowering production costs. At the same time, it also reduces errors and quality problems caused by the connection and assembly of parts.

[0068] In addition, the reinforcing component 7 can also assist in heat dissipation, dispersing the heat generated by the cylinder and the heat generated by the generator more evenly.

[0069] In this embodiment, further, combined with Figure 1 As shown, the cylinder block integrating the generator housing also includes a reinforcing member 10. The reinforcing member 10 is disposed on the outer side wall of the fixed housing 2.

[0070] Furthermore, the reinforcing member 10 includes reinforcing ribs 11; multiple reinforcing ribs 11 are provided, and the multiple reinforcing ribs 11 intersect in a grid pattern and are distributed on the outer side wall of the fixed shell 2.

[0071] Furthermore, the angle between the reinforcing rib 11 and the axis of the fixed housing 2 is set at 30°-60° and 120°-150°; the width of the reinforcing rib is preferably 5mm, and the height of the reinforcing rib is preferably 8mm.

[0072] In this embodiment, further, combined with Figure 3 and Figure 4 As shown, the cylinder block, which integrates the generator housing, also includes a flow guide component.

[0073] Specifically, the two ends of the flow guide member are respectively connected to the first heat dissipation circuit 13 of the cylinder body 1 and the second heat dissipation circuit of the generator in the fixed housing 2.

[0074] Furthermore, the cylinder body 1 includes a cylinder body 14 and a cylinder liner 15. The cylinder body 14 is fitted onto the cylinder liner 15 and a first heat dissipation circuit 13 is formed between the cylinder body 14 and the cylinder liner 15. The second heat dissipation circuit has an oil cooler. The flow guiding component includes a flow guiding pipe 12, one end of which is connected to the first heat dissipation circuit 13 and the other end is connected to the oil cooler.

[0075] In summary, the cylinder body 1 and the fixed housing 2 are integrated together and can share the cooling and heat dissipation section. Compared with the traditional separate design, the cooling pipe layout is more reasonable and the heat dissipation effect is better. It can effectively reduce the temperature of the engine and generator during operation, improve performance and extend service life.

[0076] In this embodiment, combined with Figure 7 and Figure 8 As shown, the crankshaft 18 of the engine and the rotor shaft 19 of the generator are connected by direct coupling, eliminating the need for traditional damping wheels. This direct coupling method greatly improves power transmission efficiency and reduces energy loss and wear on transmission components. In other words, the integrated design shortens the power transmission path, reduces energy loss, and allows the mechanical energy generated by the engine to be transferred to the generator more efficiently, improving power generation efficiency. Furthermore, it enables a faster response when the vehicle requires rapid acceleration or other power demands, enhancing the overall vehicle performance.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
