[0001] This application relates to the field of vehicle technology, and more specifically, to motorcycles. Background Technology

[0002] During motorcycle engine operation, an oil cooler is typically used to cool the engine oil and prevent it from overheating. However, during motorcycle assembly, the connection between the oil cooler and the engine often presents challenges such as complex structure and difficult installation, leading to low assembly efficiency. Utility Model Content

[0004] The embodiments of this application are implemented as follows:

[0005] A motorcycle includes a frame, an engine, an oil cooler, and a bracket assembly, wherein the engine is mounted on the frame. The oil cooler is mounted on one side of the engine, and the bracket assembly connects the engine and the oil cooler. The bracket assembly includes a connecting rod, a positioning member, and a bracket. One end of the connecting rod is connected to the engine, the positioning member includes a connecting portion and a positioning portion, the other end of the connecting rod is detachably connected to the connecting portion, and the bracket is fixed to one side of the oil cooler. The bracket has mounting holes, and the positioning portion is inserted into the mounting holes.

[0006] In this way, the motorcycle engine and oil cooler can be quickly, simply, and stably installed and fixed during the assembly process through the split structure of connecting rods, positioning parts, and brackets, as well as the detachable connection method between each component, effectively improving assembly efficiency.

[0007] In one possible implementation, the positioning part is elastic and substantially cylindrical, with its periphery elastically abutting against the inner wall of the mounting hole. Thus, the positioning element can be a structure with a certain degree of elasticity, utilizing elastic compressive force to reduce the problem of the positioning element loosening, and also helping to reduce product costs.

[0008] In one possible implementation, the positioning element is substantially cylindrical, and a through groove is provided in the positioning portion along the radial direction of the positioning element. The diameter of the positioning portion is larger than the diameter of the mounting hole. Thus, the positioning element is easy to install and not easily loosened during insertion into the mounting hole.

[0009] In one possible implementation, the positioning member is basically cylindrical, and a first connecting hole is provided in the connecting part along the axial direction of the positioning member, and the connecting rod part is provided in the first connecting hole.

[0010] In one possible implementation, the inner wall of the first connecting hole is threadedly connected to the outer wall of the connecting rod.

[0011] In one possible implementation, along the axial direction of the positioning member, the positioning part is provided with a second connecting hole, the second connecting hole communicates with the first connecting hole, the diameter of the second connecting hole is smaller than the diameter of the first connecting hole, and a limiting surface is formed between the first connecting hole and the second connecting hole, the surface being used to abut against the connecting rod.

[0012] In one possible implementation, a protrusion is provided at the end of the positioning part away from the connecting part. Along the axial direction of the positioning part, a positioning surface and a guide surface are respectively provided on opposite sides of the protrusion. The positioning surface is used to abut against the side of the bracket away from the connecting part, and the guide surface is inclined relative to the axis of the positioning part.

[0013] From the connecting part to the positioning part, the cross-sectional area of ​​the protrusion gradually decreases.

[0014] In one possible implementation, there are multiple bumps, which are distributed at intervals along the circumference of the positioning portion.

[0015] In one possible implementation, the end of the connecting portion facing the positioning portion is provided with a flange, which is used to abut against the side of the bracket facing the connecting portion.

[0016] In one possible implementation, the bracket assembly further includes an elastic element disposed within the mounting hole and abutting against the periphery of the positioning portion.

[0017] The motorcycle described in this application achieves quick, simple, and stable installation and fixing of the engine and oil cooler through a split structure of connecting rods, positioning parts, and brackets, as well as a detachable connection method between the components, which effectively improves assembly efficiency and also has the advantage of easy maintenance.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] See Figure 1 , Figure 2 and Figure 3This application provides a motorcycle 100, including a frame 10, an engine 20, and an oil cooler 30. The engine 20 is mounted on the frame 10. The oil cooler 30 is mounted on one side of the engine 20. The motorcycle 100 also includes a bracket assembly 40 for connecting the engine 20 and the oil cooler 30. The bracket assembly 40 includes a connecting rod 41, a positioning member 42, and a bracket 43. One end of the connecting rod 41 is connected to the engine 20. The positioning member 42 includes a connecting portion 421 and a positioning portion 422. The other end of the connecting rod 41 is detachably connected to the connecting portion 421. The bracket 43 is fixed to one side of the oil cooler 30. The bracket 43 has a mounting hole 431, and the positioning portion 422 is inserted into the mounting hole 431.

[0033] Thus, during the assembly process, the engine 20 and oil cooler 30 of the motorcycle 100 can be quickly, simply, and stably installed and fixed through the split structure of the connecting rod 41, positioning part 42, and bracket 43, as well as the detachable connection between each component, effectively improving assembly efficiency.

[0034] Please continue reading. Figure 4 , Figure 5 In one possible implementation, the periphery of the positioning part 422 abuts against the inner wall of the mounting hole 431 via an elastic element. Thus, the positioning part 422 can be a structure with a certain degree of elasticity, specifically a plastic bushing, rubber bushing, or similar structure. Utilizing elastic compressive force reduces the problem of the positioning element 42 loosening and also helps to reduce product costs.

[0035] Please continue reading. Figure 6 In some embodiments, the bracket assembly 40 further includes an elastic element 432 disposed within the mounting hole 431. The positioning portion 422 is substantially cylindrical, and the elastic element 432 abuts against the periphery of the positioning portion 422. The elastic element 432 may be an elastic washer that surrounds the inner wall of the mounting hole 431. The positioning portion 422 of the positioning element 42 is inserted into the inner hole of the elastic element 432, and the inner hole of the elastic element 432 serves as the mounting hole 431. The provision of the elastic element 432 can further fix the positioning element 42, reducing the risk of the positioning element 42 becoming loose.

[0036] Please see Figure 4 , Figure 7 and Figure 8 In some embodiments, the positioning member 42 is basically cylindrical, and a through groove 423 is provided in the positioning part 422 along the radial direction of the positioning member 42. The diameter of the positioning part 422 is larger than the diameter of the mounting hole 431. In this way, the through groove 423 can provide space for the deformation of the positioning part 422, making it convenient to insert the relatively large-diameter positioning part 422 into the mounting hole 431. After insertion, the positioning part 422 can maintain its abutment against the inner wall of the mounting hole 431 under the action of elastic restoring force, making the positioning member 42 less likely to loosen.

[0037] In some embodiments, along the axial direction of the positioning member 42, the through groove 423 has a dimension of a, and the positioning part 422 has a dimension of b, where a ≤ b. This allows the positioning part 422 to deform sufficiently during the insertion process while preventing the through groove 423 from extending into the connecting part 421 and affecting the connection strength with the connecting rod 41.

[0038] Please see Figure 4 and Figure 8 In some embodiments, along the axial direction of the positioning member 42, the connecting part 421 is provided with a first connecting hole 424, and the connecting rod 41 is partially disposed in the first connecting hole 424. In this way, the end of the connecting rod 41 can be inserted into the connecting part 421 of the positioning member 42, realizing a detachable connection. The structure is simple, the disassembly and assembly are convenient, which helps to reduce the assembly difficulty and improve the assembly efficiency.

[0039] In some embodiments, the inner wall of the first connecting hole 424 is threaded to the outer wall of the connecting rod 41, which helps to improve the connection reliability between the connecting rod 41 and the positioning member 42.

[0040] In some embodiments, along the axial direction of the positioning member 42, the positioning part 422 is provided with a second connecting hole 425, which communicates with the first connecting hole 424. The diameter of the second connecting hole 425 is smaller than the diameter of the first connecting hole 424. A limiting surface 426 is formed between the first connecting hole 424 and the second connecting hole 425, which is used to abut against the connecting rod 41. The provision of the second connecting hole 425 can, on the one hand, reduce the thickness of the positioning part 422, making it easier for the positioning part 422 to deform during the insertion process, and on the other hand, reduce the manufacturing cost of the positioning member 42.

[0041] In some embodiments, a protrusion 427 is provided at the end of the positioning part 422 away from the connecting part 421. Along the axial direction of the positioning part 422, a positioning surface 4271 and a guide surface 4272 are respectively provided on opposite sides of the protrusion 427. The positioning surface 4271 is used to abut against the side of the bracket 43 away from the connecting part 421, and the guide surface 4272 is inclined relative to the axis of the positioning part 422. From the connecting part 421 to the positioning part 422, the cross-sectional area of ​​the protrusion 427 gradually decreases, and the protrusion 427 is approximately wedge-shaped. During the insertion of the positioning part 422 into the mounting hole 431, the guide surface 4272 of the protrusion 427 helps the positioning part 422 to enter the mounting hole 431. After the protrusion 427 passes through the mounting hole 431, the positioning surface 4271 can abut against the back of the bracket 43, preventing the positioning part 422 from dislodging from the mounting hole 431. In one embodiment, the positioning surface 4271 can abut against the lower end of the elastic member 432.

[0042] In some embodiments, the number of protrusions 427 is multiple, and the multiple protrusions 427 are distributed at intervals along the circumference of the positioning portion 422. In one embodiment, the number of protrusions 427 is two, and the two protrusions 427 are symmetrically distributed on both sides of the through groove 423. In other embodiments, the number of protrusions 427 may be more than two, and the multiple protrusions 427 may be evenly distributed on the periphery of the positioning portion 422. In another embodiment, only one protrusion 427 may be provided, as long as the installation requirements are met, and this application is not limited thereto.

[0043] Please refer to it again. Figure 4 and Figure 8 In some embodiments, the end of the connecting portion 421 facing the positioning portion 422 is provided with a flange 428, which is used to abut against the side of the bracket 43 facing the connecting portion 421. In one embodiment, the flange 428 can abut against the upper end of the elastic member 432.

[0044] Thus, the flange 428 and the protrusion 427 limit the position on the upper and lower sides of the bracket 43, respectively, further reducing the risk of the positioning member 42 becoming loose and providing connection reliability for the bracket assembly 40.

[0045] The motorcycle 100 of this application achieves quick, simple, and stable installation and fixing of the engine 20 and oil cooler 30 through the split structure of the connecting rod 41, positioning component 42, and bracket 43, as well as the detachable connection between the components, effectively improving assembly efficiency and offering the advantage of easy maintenance. The split structure of the connecting rod 41 and positioning component 42 requires less installation space, making it suitable for use in confined spaces.

[0046] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
