[0035] Reference below Figure 1-Figure 5 The powertrain 100 according to an embodiment of the present invention is described. By setting the connecting structure 21 of the generator 2 to move from the loading sub-slot 1111 to the limiting sub-slot 1113 for limiting cooperation, it is easy to fix the connecting structure 21, and the limiting cooperation can prevent the connecting structure 21 from moving, which is convenient for connecting the connecting structure 21 with the engine 1. It can reduce the intensity of manual labor, simplify the installation process of the generator 2, reduce the installation cycle of the assembly process, save space, and reduce costs.

[0036] like Figure 1-Figure 5 As shown, a powertrain 100 according to an embodiment of the present invention includes an engine 1 and a generator 2 .

[0037] The engine 1 is formed with an installation groove 111, which includes a loading sub-groove 1111 and a limiting sub-groove 1113. A loading port 1112 is formed at one end of the loading sub-groove 1111, and the limiting sub-groove 1113 is connected to the other end of the loading sub-groove 1111 and is at least partially lower than the loading sub-groove 1111.

[0038] Specifically, the installation groove 111 is designed with two parts, namely the loading sub-groove 1111 and the limiting sub-groove 1113. The loading sub-groove 1111 is connected to the limiting sub-groove 1113 and is connected to the outside of the limiting sub-groove 1113, and one end of the loading sub-groove 1111 is formed with a loading port 1112 for loading other structures. The other end of the loading sub-groove 1111 is connected to the limiting sub-groove 1113, and at least part of the limiting sub-groove 1113 is lower than the loading sub-groove 1111, so that the structure entering the limiting sub-groove 1113 can be limited and will not reversely enter the loading sub-groove 1111, so as to realize the limiting and installation functions of the installation groove 111.

[0039] The loading sub-groove 1111 can be configured as a square groove, a strip groove, etc., and the limiting sub-groove 1113 can be configured as a U-shaped groove, a strip groove, and the extension directions of the loading sub-groove 1111 and the limiting sub-groove 1113 can intersect, and the groove widths of the two can be the same. This facilitates the installation of other structures in the installation groove 111, and has a simple structure, convenient processing, and lower processing costs. The loading sub-groove 1111 can be configured to extend horizontally or obliquely.

[0040] The generator 2 is equipped with a connecting structure 21 , at least part of which is adapted to enter the loading sub-slot 1111 from the loading port 1112 and move along the loading sub-slot 1111 to the limiting sub-slot 1113 to engage with the limiting sub-slot 1113 .

[0041] Specifically, the connecting structure 21 is used to install the generator 2 in the installation groove 111. The connecting structure 21 is detachably connected to the generator 2. During installation, the connecting structure 21 is first connected to the generator 2, and then at least a portion of the connecting structure 21 is extended from the loading port 1112 to the loading sub-groove 1111, and the connecting structure 21 moves along the length direction of the loading sub-groove 1111 to the limiting sub-groove 1113, wherein the connecting structure 21 can slide along the loading sub-groove 1111 to the limiting sub-groove 1113, or, a slight thrust is applied manually to gently push the connecting structure 21 into the limiting sub-groove 1113 to achieve limiting and supporting the connecting structure 21, and then the connecting structure 21 is connected and fixed to the engine 1, so that the connection and fixation of the generator 2 and the engine 1 can be achieved, and the installation is easy and effortless.

[0042] Therefore, the commonly used hole-type connection requires bolts to be inserted into the mounting holes on the engine block 14. This makes the bolt installation difficult during the assembly process and requires the installer to constantly hold the generator 2 in their hands, which increases the installation difficulty. In this embodiment, the provision of the insertion sub-slot 1111 and the limiting sub-slot 1113 allows the connection structure 21 to enter the limiting sub-slot 1113 from the insertion sub-slot 1111, making the installation of the connection structure 21 easier and more convenient, reducing labor intensity, simplifying the installation process, and improving assembly efficiency, thereby improving production efficiency. The assembly process also requires a smaller space, which facilitates assembly work and reduces assembly costs. The movement of the connection structure 21 along the insertion sub-slot 1111 can improve the installation accuracy of the connection structure 21. The limiting sub-slot 1113 also has a limiting and fixing function, preventing the connection structure 21 from moving back out, thereby making the assembly of the connection structure 21 with the engine 1 more reliable and improving the compatibility of the engine 1 and the generator 2.

[0043] According to the powertrain 100 of the embodiment of the present utility model, the connecting structure 21 of the generator 2 is arranged to move from the loading sub-slot 1111 to the limiting sub-slot 1113 for limiting cooperation. In this way, the connecting structure 21 is easy to fix, and the limiting cooperation can prevent the connecting structure 21 from moving, which is convenient for the connection between the connecting structure 21 and the engine 1. It can reduce the intensity of manual labor, simplify the installation process of the generator 2, reduce the installation rhythm of the assembly process, improve the installation efficiency, save space, and reduce costs.

[0044] In some embodiments, the loading sub-groove 1111 is configured as an inclined groove, and the loading sub-groove 1111 is configured to extend downwardly from one end where the loading port 1112 is formed to one end connected to the limiting sub-groove 1113 .

[0045] Specifically, the sub-slot 1111 plays a role in assisting installation, such as Figure 4 and Figure 5 As shown, the loading sub-groove 1111 can be constructed as a square groove, etc., and the limiting sub-groove 1113 can be constructed as a U-shaped groove. The limiting sub-groove 1113 is open upward, and the loading sub-groove 1111 is connected to the open side of the limiting sub-groove 1113. The loading sub-groove 1111 can be constructed as an inclined groove, and extends downwardly from the loading inlet 1112 to the limiting sub-groove 1113. In this way, the connecting structure 21 is extended from the loading inlet 1112 into the loading sub-groove 1111, and the connecting structure 21 is slid from the top to the bottom into the limiting sub-groove 1113. The entire installation process is easy and labor-saving, which can improve the installation efficiency of the connecting structure 21 in the installation groove 111, and the structure is simple and easy to process. Among them, the shapes of the loading sub-groove 1111 and the limiting sub-groove 1113 are not limited to those described in this embodiment, and can also be set as slots of other shapes.

[0046] Therefore, by setting the loading sub-groove 1111 as an inclined groove, the connecting structure 21 can be easily slid into the limiting sub-groove 1113 with the help of part of the gravity, which can reduce more external force, speed up the installation speed, and can naturally move into the limiting sub-groove 1113, reducing the need for manual adjustment. When the connecting structure 21 moves into the limiting sub-groove 1113, the possibility of it moving back toward the loading sub-groove 1111 is reduced, thereby improving the reliability of the installation of the connecting structure 21, and reducing the friction and wear between the connecting structure 21 and the loading sub-groove 1111, thereby improving the installation efficiency and quality.

[0047] In some embodiments, the inclination angle of the loading sub-slot 1111 relative to the horizontal direction is A, and satisfies: 10°≤A≤15°.

[0048] Specifically, the loading sub-slot 1111 extends downwardly along a straight line from the loading port 1112 to the limiting sub-slot 1113, forming an inclined angle A with the horizontal direction. The value of A can be 10°, 12°, 15°, etc. By setting the above values, the angle between the loading sub-slot 1111 and the horizontal direction can be acute and relatively small. In this way, when the connecting structure 21 is installed, a certain guiding effect is formed at the loading sub-slot 1111. After the installer supports the generator 2 by hand or mechanically, and aligns the connecting structure 21 with the installation slot 111, the generator 2 can automatically slide to the bottom of the installation slot 111, reducing the intensity of manual labor and increasing the assembly efficiency of the production line. The value of the inclined angle is not limited to that described in this embodiment and can be selectively set according to actual installation requirements.

[0049] Therefore, by setting the tilt angle A to satisfy: 10° ≤ A ≤ 15°, a balance point is provided, allowing the connecting structure 21 to enter the installation slot 111 by gravity, while also preventing the connection structure 21 from sliding due to excessive tilt angles. This angle range helps reduce the excessive external force required during installation, and makes it easier to place the connecting structure 21 in the correct position. It also optimizes space utilization, making the installation of the connecting structure 21 easy and safe, and facilitating manual installation. At the same time, it maintains the stability of the connecting structure 21 within the slot, reduces friction during the installation process, and improves the strength of the connecting structure 21.

[0050] In some embodiments, the engine 1 has a mounting bracket 11, and a mounting groove 111 is formed in the mounting bracket 11. The mounting bracket 11 can be integrally formed with the engine 1, or can be connected and fixed to the engine 1 by bolts or other connecting parts, such as Figure 2As shown, the mounting bracket 11 protrudes from the surface of the engine 1, and the loading sub-groove 1111 of the mounting groove 111 is located in the outer area of the mounting bracket 11, and an open loading port 1112 is formed at the end of the mounting bracket 11, which is conducive to the connection structure 21 entering the mounting groove 111 from the loading port 1112. The connection and fixation of the connection structure 21 to the mounting bracket 11 can be achieved through the mounting groove 111.

[0051] The generator 2 is provided with a connecting bracket 22 , the connecting structure 21 passes through the connecting bracket 22 , and the connecting bracket 22 forms an escape space 221 . The mounting bracket 11 extends into the escape space 221 so that the connecting structure 21 is installed and matched with the mounting groove 111 .

[0052] Specifically, the connecting bracket 22 can be integrally formed with the generator 2, or can be connected and fixed to the generator 2 by connecting members such as bolts, wherein the connecting structure 21 is connected to the connecting bracket 22 through the connecting structure 21 to achieve the fixation of the connecting structure 21. The two can be connected by other fasteners such as bolts and pins, and as Figure 3 As shown, the connecting bracket 22 is formed with an escape space 221 , which is open toward one side of the mounting bracket 11 and is used to escape the mounting bracket 11 . The connecting structure 21 passes through both ends of the escape space 221 and is connected to the connecting bracket 22 .

[0053] Furthermore, during installation, the connecting bracket 22 is directed toward the mounting bracket 11, and the mounting bracket 11 is extended into the avoidance space 221, while the connecting structure 21 is extended from the loading port 1112 into the mounting groove 111, so that the connecting bracket 22 and the mounting bracket 11 can be plugged in and matched. Through the plug-in fit, the contact area between the connecting bracket 22 and the mounting bracket 11 is increased, and combined with the connection and fixation of the connecting structure 21 and the mounting groove 111, the connection strength between the generator 2 and the engine 1 can be improved, thereby ensuring the reliability and stability of the powertrain 100.

[0054] In some embodiments, the connecting bracket 22 includes two connecting side plates 222 . The two connecting side plates 222 are spaced apart and an avoidance space 221 is formed between the two connecting side plates 222 .

[0055] Specifically, the two connecting side panels 222 are used to realize the installation of the connecting structure 21. The two connecting side panels 222 are spaced apart to form an avoidance space 221, which can provide installation space for the extended part of the mounting bracket 11, so that the two connecting side panels 222 are located on the outside of the mounting bracket 11, and the connecting structure 21 is installed and matched with the mounting groove 111 of the mounting bracket 11.

[0056] The connecting structure 21 includes a connecting bolt 211 and a connecting nut 212. The connecting bolt 211 includes a bolt head 2111 and a bolt rod 2112. One end of the bolt rod 2112 is connected to the bolt head 2111 and the other end is threadedly connected to the connecting nut 212. The bolt rod 2112 passes through the two connecting side plates 222. The bolt head 2111 and the connecting nut 212 are respectively located on the sides of the two connecting side plates 222 facing away from each other. The bolt rod 2112 is clamped in the mounting groove 111.

[0057] Specifically, if Figure 3 As shown, the connection structure 21 can be a connecting bolt 211 and a connecting nut 212 that are installed in combination. The bolt rod 2112 of the connecting bolt 211 extends along the distribution direction of the two connecting side plates 222, wherein the two connecting side plates 222 are respectively provided with a connecting hole, and the two connecting holes are both set in the area of the two connecting side plates 222 away from the generator 2. The two connecting holes pass through the two connecting side plates 222 respectively, and the aperture of the connecting hole is larger than the outer diameter of the bolt rod 2112. During installation, the bolt rod 2112 is passed from one connecting side plate 222 to the other connecting side plate 222, and the bolt head 2111 is attached to one connecting side plate 222, and the connecting nut 212 is threadedly connected to the bolt rod 2112 on the outer side of the other connecting side plate 222, and the connecting bolt 211 and the connecting nut 212 are pre-tightened first.

[0058] The pre-installed generator 2 is installed on the engine 1, the mounting bracket 11 is inserted into the avoidance space 221, and the bolt rod 2112 is clamped into the mounting groove 111, and then the connecting nut 212 and the connecting bolt 211 are locked, so that the connection between the connecting structure 21 and the connecting side plate 222 is firm and reliable, which can improve the connection strength between the generator 2 and the engine 1. The overall structure is simple and convenient to install. The assembly process does not require manual alignment of the threaded holes and the bolt tightening process does not require manual holding of the generator 2, which greatly reduces the intensity of manual work and also increases the assembly efficiency of the production line.

[0059] In some embodiments, one of the two connecting side plates 222 is provided with a limiting boss 2221 , and the limiting boss 2221 is suitable for pressing against the connecting nut 212 to limit the circumferential position of the connecting nut 212 .

[0060] Specifically, the limiting boss 2221 is provided on a side of the connecting side plate 222 away from the avoidance space 221, and the limiting boss 2221 is located on the side of the connecting nut 212 close to the generator 2, and the limiting boss 2221 protrudes along the surface of the connecting side plate 222, wherein the limiting boss 2221 can be constructed as a rectangular boss for pressing and fitting with the connecting nut 212. In this way, when the connecting bolt 211 passes through the two connecting side plates 222 and is threadedly connected to the connecting nut 212, the limiting boss 2221 exerts pressure on the connecting nut 212, which can prevent the connecting nut 212 from rotating circumferentially to ensure that the position of the connecting nut 212 on the connecting side plate 222 is fixed, that is, only the connecting bolt 211 needs to be screwed in during installation, and the connecting nut 212 does not need to be re-fixed during the installation process, thereby improving the assembly efficiency of the production line. It has a simple structure, is easy to process, and has reliable limiting. Furthermore, the shape of the limiting boss 2221 is not limited to that described in this embodiment, and the limiting boss 2221 may also be constructed in one or more other shapes.

[0061] Therefore, by setting the limiting boss 2221, it can be ensured that the connecting nut 212 will not rotate unnecessarily when subjected to external force, and the installation error can be reduced, and the stiffness and load-bearing capacity of the entire connecting structure 21 can be improved. Under dynamic load or vibration environment, the limiting boss 2221 can prevent the connecting nut 212 from losing its fastening effect due to loosening, so as to improve the stability and reliability of the connection.

[0062] In some embodiments, there are at least two mounting slots 111 and connection structures 21 , and they are installed in a one-to-one correspondence. The at least two mounting slots 111 are spaced apart and distributed on the engine 1 along the up-down direction.

[0063] Specifically, the engine 1 is provided with at least two mounting slots 111, and the generator 2 is provided with at least two connecting structures 21, that is, the generator 2 is provided with at least two connecting brackets 22. The at least two mounting slots 111 are spaced apart in the vertical direction, and the at least two connecting structures 21 correspond to the at least two mounting slots 111 in a one-to-one manner, ensuring that the components are properly installed. The number of mounting slots 111 and the number of connecting structures 21 can each be two, three, or the like.

[0064] Furthermore, during installation, at least two connection structures 21 are aligned with at least two installation grooves 111 respectively, so that the engine 1 and the generator 2 can be connected at at least two connection positions, thereby improving the connection strength between the generator 2 and the engine 1, thereby improving the overall performance.

[0065] In some embodiments, the mounting grooves 111 and the connecting structure 21 are both two and are installed in a one-to-one correspondence. The two mounting grooves 111 are respectively a first mounting groove 1114 and a second mounting groove 1115. Figure 2As shown, the first mounting groove 1114 is located in the upper area of the engine 1, and the second mounting groove 1115 is located in the lower area of the engine 1. Figure 3 As shown, the generator 2 is provided with two connecting brackets 22, and the two connecting brackets 22 are correspondingly connected with a connecting structure 21. In this way, by plugging and connecting the two connecting structures 21 with the first mounting groove 1114 and the second mounting groove 1115 respectively, the generator 2 can be connected and fixed to the engine 1 in the upper and lower directions through the two mounting grooves 111, which can improve the connection performance between the generator 2 and the engine 1.

[0066] The engine 1 includes an engine timing cover 13 and an engine block 14 . The engine timing cover 13 forms a first mounting groove 1114 . The engine timing cover 13 and the engine block 14 together form a second mounting groove 1115 .

[0067] Specifically, the engine 1 includes a connected engine timing cover 13 and an engine cylinder block 14. The engine timing cover 13 is used to protect transmission structures such as chains and gears to prevent them from being corroded by dust, moisture and other impurities. The engine cylinder block 14 is used to install and position various components inside the engine 1.

[0068] like Figure 1 As shown, the generator 2 is connected to the middle area of the engine timing cover 13, and a mounting bracket 11 is provided in the upper area of the engine timing cover 13, and a first mounting groove 1114 is formed in the mounting bracket 11. The engine timing cover 13 and the engine cylinder block 14 are jointly provided with a mounting bracket 11 in the lower area, and a second mounting groove 1115 is formed in the mounting bracket 11. In this way, the second mounting groove 1115 is formed by the engine timing cover 13 and the engine cylinder block 14, so that the engine timing cover 13 and the engine cylinder block 14 can both be used to bear the weight of the generator 2, and can share the force of the engine timing cover 13, so as to improve the service life of the engine timing cover 13.

[0069] Among them, the second mounting groove 1115 and the first mounting groove 1114 can both be arranged on the engine timing cover 13, or the second mounting groove 1115 and the first mounting groove 1114 can both be arranged on the engine cylinder block 14, that is, the two mounting brackets 11 can be arranged on the engine timing cover 13 or the engine cylinder block 14 at the same time, as long as the strength requirements for the installation of the generator 2 are met. The setting methods are diverse and can be set according to actual space requirements.
