Description

Technical Field

[0001] This application relates to the field of vehicle engineering, and more particularly to a motorcycle. Background Technology

[0002] When a motorcycle is in motion, the front wheel kicks up dirt, gravel, and other debris from the ground. This debris, due to inertia, splashes onto the motorcycle body, engine, and rider. To avoid this problem, a front fender is usually installed at the front wheel. The front fender covers at least part of the front wheel and is connected to the motorcycle's underbody panel. The end of the underbody panel facing away from the front wheel is connected to the motorcycle's steering column.

[0003] However, due to the strong permeability of mud and water, some of it can still seep into the steering column through the gap between the front fender and the lower connecting plate, causing the steering column to rust, resulting in steering sticking and reducing the lifespan of the steering column and its surrounding components. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with a longer service life of its steering column and its peripheral components.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a motorcycle including a frame, a running gear, a suspension system, and a body panel. The running gear includes a front wheel, at least partially located under the frame. The suspension system includes a front suspension connected to the front of the frame, the front suspension including a front shock absorber, a lower clamp, and a steering column. One end of the front shock absorber is connected to the front wheel, and the other end is fixedly connected to the lower clamp. The steering column is fixedly connected to the lower clamp and located on the side of the lower clamp away from the front shock absorber. The body panel includes a front fender connected to the lower clamp, the front fender covering a portion of the front wheel, the front fender having a through-hole, at least a portion of the lower clamp passing through the through-hole, and the body panel further including a sealing structure connected to the front fender and located on the inner edge of the front fender around the through-hole, the sealing structure abutting against the lower clamp.

[0007] Furthermore, the sealing structure is arc-shaped and abuts against the rear sidewall of the lower connecting plate along an extension direction perpendicular to the steering column.

[0008] Furthermore, the front suspension also includes a steering bearing, which is mounted on the steering column and connected to the lower control plate. The frame also includes a head tube, and the outer edge of the steering bearing is fixedly connected to the inner wall of the head tube, allowing the steering column to rotate relative to the head tube. The connection between the sealing structure and the lower control plate is lower than the connection between the steering bearing and the lower control plate.

[0009] Furthermore, the sealing structure includes a connected rubber part and a foam part, the rubber part being connected to the front fender and the foam part being pressed against the lower connecting plate.

[0010] Furthermore, sheet metal parts are embedded within the foam section.

[0011] Furthermore, a hollow chamber is formed inside the foam section.

[0012] Furthermore, the sealing structure has a generally U-shaped receiving groove, and the front fender includes a connecting portion embedded in the receiving groove, the connecting portion being plate-shaped.

[0013] Furthermore, the receiving groove has multiple ribs, all of which are in contact with the surface of the connecting part, and the multiple ribs are distributed at intervals in the depth direction of the receiving groove.

[0014] Furthermore, the front fender is connected to the lower connecting plate by fasteners, the extension direction of which is perpendicular to the extension direction of the steering column and substantially parallel to the clamping direction of the sealing structure.

[0015] Furthermore, the front fender includes a first baffle and a second baffle, which are detachably connected, and the first baffle is located in front of the second baffle; both the first baffle and the second baffle have arc-shaped notches on their opposite sides, and the notches of the first baffle and the second baffle are combined to form a mounting hole; the inner edges of the notches of the first baffle and the second baffle are provided with sealing structures.

[0016] The motorcycle provided in this application, by setting a sealing structure that abuts against the lower connecting plate along the extension direction perpendicular to the steering column, avoids mud and water splashing onto the steering column when the motorcycle is driven in the rain or after rain, which would cause the steering column to rust and the steering to stick, thereby improving the service life of the motorcycle's steering column and its surrounding components.

[0024] like Figure 1 and Figure 2 As shown, this application provides a motorcycle 100, which includes a frame 11, a running gear 12, a suspension system 13, and a body panel 14. The frame 11 constitutes the main frame of the motorcycle 100. The running gear 12 includes a front wheel 121 and a rear wheel 122, with at least a portion of the front wheel 121 and at least a portion of the rear wheel 122 located below the frame 11. The suspension system 13 includes a front suspension 131, which is connected between the frame 11 and the front wheel 121. The front suspension 131 includes a front shock absorber 1311, a lower connecting plate 1312, and a steering column 1313. One end of the front shock absorber 1311 is connected to the front wheel 121, and the other end of the front shock absorber 1311 is fixedly connected to the lower connecting plate 1312. The steering column 1313 is fixedly connected to the lower connecting plate 1312 and is located on the side of the lower connecting plate 1312 opposite to the front shock absorber 1311. The body panel 14 includes a front fender 141 connected to the lower panel 1312, the front fender 141 covering at least a portion of the front wheel 121.

[0025] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The motorcycle 100 is shown in the front-back, left-right, and up-down directions. It should be noted that the front-back, left-right, and up-down directions in this article refer to the directions of the motorcycle 100 when it is on a horizontal road. In the following description of the technical solution of this application, the length direction of the frame 11 is parallel to the front-back direction of the motorcycle 100, the width direction of the frame 11 is parallel to the left-right direction of the motorcycle 100, and the height direction of the frame 11 is parallel to the up-down direction of the motorcycle 100.

[0026] like Figure 3As shown, in one implementation, the front fender 141 has a through mounting hole 1411, through which at least a portion of the lower connecting plate 1312 passes. The body panel 14 also includes a sealing structure 142 connected to the front fender 141 and located on the inner edge of the front fender 141 around the mounting hole 1411, the sealing structure 142 abutting against the lower connecting plate 1312 in an extension direction perpendicular to the steering column 1313.

[0027] Specifically, the lower connecting plate 1312 has an arc-shaped rear sidewall 1312a, and the sealing structure 142 is arc-shaped. The sealing structure 142 has a sealing surface 1421 that abuts against the rear sidewall 1312a. The shape of the sealing surface 1421 is basically the same as that of the rear sidewall 1312a, so that the sealing surface 1421 and the rear sidewall 1312a have a high degree of fit, thereby improving the sealing effect of the sealing structure 142.

[0028] Furthermore, the front fender 141 is connected to the lower connecting plate 1312 by fasteners. The extension direction of the fasteners is perpendicular to the extension direction of the steering column 1313 and is basically parallel to the abutting direction of the sealing structure 142. The fasteners make the sealing structure 142 fit tightly with the lower connecting plate 1312, further improving the sealing effect of the sealing structure 142.

[0029] With the above configuration, the sealing structure 142 is pressed against the lower connecting plate 1312 in the extension direction perpendicular to the steering column 1313, which prevents mud and water brought up by the front wheel 121 from penetrating the connection between the lower connecting plate 1312 and the front fender 141, prevents the steering column 1313 and its surrounding components from rusting and causing steering jamming, and improves the service life of the motorcycle 100.

[0030] like Figure 3 As shown, in one implementation, the front fender 141 includes a first baffle 1412 and a second baffle 1413, which are detachably connected, with the first baffle 1412 located in front of the second baffle 1413. Both the first baffle 1412 and the second baffle 1413 have arc-shaped notches on their opposing sides. When the first baffle 1412 is connected to the second baffle 1413, the notches of the first baffle 1412 and the second baffle 1413 combine to form a mounting hole 1411, through which at least a portion of the lower connecting plate 1312 passes.

[0031] In the implementation of this application, a sealing structure 142 is provided on the inner edge of the notch of the second baffle 1413 to prevent the splashing of mud and water brought up by the front wheel 121 when the motorcycle 100 moves forward.

[0032] As an optional implementation, the inner edge of the notch of the first baffle 1412 and the second baffle 1413 is provided with a sealing structure 142. The sealing structure 142 blocks the gap between the front of the lower connecting plate 1312 and the edge of the mounting hole 1411, as well as the gap between the rear of the lower connecting plate 1312 and the edge of the mounting hole 1411, thereby further improving the sealing effect of the sealing structure 142.

[0033] like Figure 4 As shown, in one implementation, the front suspension 131 also includes a steering bearing 1314, which is mounted on the steering column 1313 and connected to the lower connecting plate 1312. The frame 11 also includes a head tube (not shown), and the outer edge of the steering bearing 1314 is fixedly connected to the inner wall of the head tube, so that the steering column 1313 can rotate relative to the head tube.

[0034] The connection between the sealing structure 142 and the lower connecting plate 1312 is lower in height than the connection between the steering bearing 1314 and the lower connecting plate 1312, so as to prevent mud and water carried by the motorcycle 100 during driving from splashing onto the steering bearing 1314 and causing the steering bearing 1314 to rust, thereby further improving the service life of the motorcycle 100.

[0035] like Figure 5 As shown, in one implementation, the sealing structure 142 has a generally U-shaped receiving groove 1422, and the front fender 141 includes a connecting portion 1414 embedded in the receiving groove 1422, the connecting portion being in the form of a thin plate.

[0036] Specifically, the receiving groove 1422 has multiple ribs 1423, all of which are in contact with the surface of the connecting portion 1414. These ribs 1423 are spaced apart along the depth of the receiving groove 1422. Mud and water splashed onto the sealing structure 142 need to flow along the connecting portion through the multiple ribs 1423 before reaching the steering column 1313. Each rib 1423 can impede the flow of mud and water towards the steering column 1313, thereby improving the sealing effect of the sealing structure 142.

[0037] As one implementation, the sealing structure 142 includes a rubber portion 1424 and a foam portion 1425, with the foam portion 1425 integrally formed with the rubber portion 1424. The rubber portion 1424 is connected to the front fender 141, and the side of the foam portion 1425 facing away from the rubber portion 1424 abuts against the lower connecting plate 1312. The foam portion 1425 undergoes elastic deformation when compressed, filling the gap between the front fender 141 and the lower connecting plate 1312.

[0038] It should be noted that the foam part 1425 exhibits a greater degree of elastic deformation when compressed than the rubber part 1424, and the foam part 1425 has stronger fatigue resistance. That is, the foam part 1425 can maintain strong elasticity even when subjected to long-term compression, thereby extending the replacement cycle of the sealing structure 142.

[0039] Specifically, the foam part 1425 is embedded with a sheet metal part (not shown in the figure). The sheet metal part has high hardness to support the foam part 1425 from the inside, so as to prevent the foam part 1425 from being over-deformed due to compression, which would cause gaps between the over-deformed foam part 1425 and the lower connecting plate 1312, and ensure that the sealing structure 142 has a good sealing effect.

[0040] Furthermore, a hollow chamber is formed inside the foam section 1425, which can provide sufficient deformation space for the foam section 1425 when it is compressed, ensuring that the foam section 1425 undergoes sufficient deformation to seal the gap between the foam section 1425 and the lower connecting plate 1312.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
