[0024] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] An embodiment of the present application provides a vehicle that includes a powertrain, which is the core component of the vehicle and is used to provide power for the vehicle's movement. The powertrain includes an engine and a mounting structure for mounting the engine. By mounting the engine to the mounting structure, the engine is stably installed, thereby ensuring that the engine's position does not shift under complex road conditions, thereby improving driving safety and reliability. The vehicle can be a motorcycle, an electric vehicle, or other means of transportation, without limitation.

[0026] The following describes in detail the installation structure of a motorcycle engine as an example.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the present application provides an engine mounting structure, including a frame 10, a first suspension arm 20, a second suspension arm 30 and an adjusting member. The frame 10 can be an accessory part of the frame of a motorcycle. The first suspension arm 20 and the second suspension arm 30 are both fixed to the frame 10. In order to ensure the overall strength and stability, the first suspension arm 20 and the second suspension arm 30 are both fixed by welding. The first suspension arm 20 and the second suspension arm 30 are respectively located on both sides of the frame 10. An engine mounting area is formed between the frame 10, the first suspension arm 20 and the second suspension arm 30. When installing the engine, the engine is first placed in the mounting area so that the engine is aligned with the preset positioning holes, mounting holes, etc. on the frame 10. The adjusting member is also passed through the engine, and is also passed through the first suspension arm 20 and the second suspension arm 30 and is used to adjust the distance between the engine installed in the mounting area and the frame 10. The main function of the adjustment member is to control the gap between the engine and the frame. If there is a positive deviation in the welding of the first and second suspension arms 20 and 30, the adjustment member can be tightened to achieve a tight connection between the engine and the frame. If there is a negative deviation during welding, the adjustment member can be loosened to achieve a tight connection between the frame and the engine. This structure also reduces costs, while ensuring a stable engine installation and ensuring the safety of the motorcycle during driving.

[0028] like Figure 3 As shown, the adjusting member includes a connecting shaft 40, a stopper 50, a nut 60, and a screw sleeve 70. The stopper 50 is provided at one end of the connecting shaft 40 to prevent the connecting shaft 40 from falling off the first suspension arm 20 and the second suspension arm 30. The nut 60 is provided at the other end. The end of the connecting shaft 40 near the nut 60 is sleeved with a screw sleeve 70. The screw sleeve 70 is installed in the first suspension arm 20 or the second suspension arm 30. The screw sleeve 70 here not only plays a good adjustment role, but also plays a good supporting role. The screw sleeve 70 supports the shaft and the engine by tightening the nut 60. Specifically, the nut 60 and the screw sleeve 70 are indirectly connected, with a flat washer and a spring washer added in the middle to prevent the screw sleeve 70 from deforming and affecting its strength when the nut 60 is tightened. At the same time, the transition connection of the spring washer and the flat washer can also enhance the preload force of the nut 60, which can reduce the problem of the nut 60 being easy to loosen during riding. This structure can also reduce costs and ensure the safety of the motorcycle during driving.

[0029] Specifically, a stopper 50 is disposed at one end of the connecting shaft 40 near the first boom 20, and a threaded sleeve 70 is disposed within the second boom 30. Both the stopper 50 and the nut 60 are positioned outside the mounting area. By rotating the nut 60, threaded sleeve 70 is adjusted, allowing the threaded sleeve 70 to act and change the distance between the engine and the vehicle frame. An annular mounting seat 80 is disposed at the bottom end of each of the first boom 20 and the second boom 30. The annular mounting seat 80 has a through hole formed therein, and the threaded sleeve 70 is mounted within the annular mounting seat 80 at the bottom end of the second boom 30.

[0030] In the present application, it should be noted that the mounting position of the first boom 20 on the frame 10 and the mounting position of the second boom 30 on the frame 10 are at the same horizontal height, and the bottom end of the first boom 20 and the bottom end of the second boom 30 are at the same horizontal height. Correspondingly, the two through holes on the two annular mounting seats 80 are also at the same horizontal height. This facilitates the insertion of the connecting shaft 40 so that the engine can be installed in the mounting area. At the same time, the gap between the engine and the frame can also be within a reasonable range.

[0031] Specifically, a first load-bearing arm 21 is provided between the top and bottom ends of the first boom 20, and a second load-bearing arm 31 is provided between the top and bottom ends of the second boom 30. The first load-bearing arm 21 and the second load-bearing arm 31 work together to bear the weight of the engine. In order to make the installation between the engine and the frame more compact, the length of the second load-bearing arm 31 is set to be greater than the length of the first load-bearing arm 21. In this way, the installation space becomes larger, and the engine can be smoothly inserted.

[0032] Since the first load-bearing arm 21 is relatively long, in order to ensure that the first load-bearing arm 21 breaks when bearing weight, a reinforcing rib 90 is further provided between the top end of the first suspension arm 20 and the first load-bearing arm 21 .

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
