[0040] See Figure 1 As shown, an embodiment of the present invention provides a saddle-type riding vehicle 100, which includes but is not limited to a motorcycle and an electric motorcycle.

[0041] The saddle-type riding vehicle 100 includes a front fork 102, a front wheel 103, and handlebars 104 connected to a frame 101. Specifically, the front wheel 103 is connected to the front fork 102, and the handlebars 104 are connected to the front fork 102. The front fork 102 is connected to a stem tube 101a located at the front end of the frame 101. Operating the handlebars 104 allows the front fork 102 to rotate relative to the stem tube 101a, thereby steering the front wheel 103. A fuel tank 105 is mounted astride the upper portion of the frame 101, a seat 106 is mounted at the upper rear portion of the frame 101, an engine 107 is connected to the lower front portion of the frame 101, a swing arm 108 is connected to the lower rear portion of the frame 101, and is suspended from the frame 101 via a rear shock absorber (not shown). A rear wheel 112 is connected to the rear end of the swing arm 108.

[0042] In some embodiments, the intake system of the engine 107 includes a fuel-air metering device such as a carburetor 109, an intake pipe, and an air filter. The exhaust system of the engine 107 consists of an exhaust pipe and a muffler. The saddle-type riding vehicle 100 is also provided with side covers for covering the sides of the frame 101, a seat cover for covering the rear portion of the frame 101 below the seat 106, a front fender 110 for covering the upper portion of the front wheel 103, and a rear fender 111 for covering the upper portion of the rear wheel 112. Drive from the engine 107 is transmitted from the engine 107 to a driven wheel sprocket mounted on the rear wheel hub of the rear wheel 112 assembly.

[0043] In some embodiments, combined Figures 1 to 3 As shown, the front fork 102 is fixedly connected to the upper connecting plate 113 and the lower connecting plate 114, and is rotatably connected to the faucet tube 101a through the upper connecting plate 113 and the lower connecting plate 114. For example, a rotating shaft 115 is connected between the upper connecting plate 113 and the lower connecting plate 114, and the rotating shaft 115 is rotatably provided in the faucet tube 101a.

[0044] In some embodiments, the handlebar 104 is fixed above the upper connecting plate 113 , and a light bracket 116 is connected between the upper connecting plate 113 and the lower connecting plate 114 . The light bracket 116 can be used to install a headlight 117 .

[0045] For the saddle-type riding vehicle 100, the braking system adopts an anti-lock braking system ("Anti-lock Brake System", hereinafter referred to as "ABS"). In some embodiments, the handlebar 104 is provided with a brake cylinder 118, and an ABS unit 119 is fixedly provided at a position corresponding to the rear side of the stem tube 101a of the frame 101. In some embodiments, the ABS unit 119 can be installed on the right side of the frame 101.

[0046] One embodiment of the present invention relates to a brake piping structure for a saddle-type riding vehicle 100. The brake piping structure may include piping structures for braking the front wheel 103 and piping structures for braking the rear wheel 112. For ease of description, the piping structure used for braking the front wheel 103 is referred to as the front-wheel brake piping structure, and the piping structure used for braking the rear wheel 112 is referred to as the rear-wheel brake piping structure.

[0047] The front wheel brake piping structure includes a brake hose for connecting between the brake cylinder 118 and the ABS unit 119. The brake hose is used to transmit the brake fluid pressure provided by the brake cylinder 118 to the ABS unit 119 to meet the braking needs of the front wheel 103. Figure 3 and Figure 4 As shown, the front wheel brake piping structure includes a front hose 120, a rear hose 121, and an adapter 122 connecting the two. The front hose 120 is fixedly connected to the brake cylinder 118 and the adapter 122 at both ends, respectively. One end of the rear hose 121 is connected to the front hose 120 via the adapter 122, and the other end extends toward the rear end of the vehicle frame 101 to the ABS unit 119. Thus, the front hose 120 and the rear hose 121, connected via the adapter 122, form an oil circuit between the brake cylinder 118 and the ABS unit 119.

[0048] Combine Figure 5As shown, the adapter 122 is connected to the position of the headlight bracket 116 corresponding to the front side of the stem pipe 101a, and the ABS unit 119 is fixed to the position of the rear side of the frame 101 corresponding to the stem pipe 101a. Therefore, the front hose 120 connected between the adapter 122 and the brake cylinder 118 will maintain a stable relative position with the headlight bracket 116, and will not move relative to the headlight bracket 116 as the handlebar 104 rotates. Based on this, when the piping space between the headlight bracket 116 and the stem pipe 101a is limited, the front hose 120 can still be compactly arranged from the handlebar 104 to the adapter 122 of the headlight bracket 116 without limiting the rotation flexibility of the handlebar 104. As for the rear hose 121, one end of the rear hose 121 is connected to the adapter 122 on the light bracket 116, and the other end is connected to the ABS unit 119 on the vehicle frame 101. Therefore, even if the light bracket 116 rotates relative to the vehicle frame 101 during rotation of the handlebar 104, causing the rear hose 121 to inevitably move with it, the adapter 122 on the light bracket 116 is relatively close to the stem pipe 101a, so the deflection of the rear hose 121 is minimal. It can be understood that the closer the light bracket 116 and the stem pipe 101a are arranged, the closer the adapter 122 can be positioned to the stem pipe 101a, thus minimizing the deflection of the rear hose 121. This eliminates the need for a longer rear hose 121 to prevent it from restricting rotation of the handlebar 104. Consequently, this brake piping structure minimizes piping length, saving costs.

[0049] Combine Figures 4 to 6 As shown, the adapter 122 includes a first pipe joint 122a and a second pipe joint 122b that are connected to the front hose 120 and the rear hose 121, respectively. The first pipe joint 122a and the second pipe joint 122b are perpendicular to each other. This arrangement allows the ends where the front hose 120 and the rear hose 121 connect to each other to be arranged vertically, facilitating the routing of the front hose 120 in a generally vertical direction and allowing the rear hose 121 to extend generally toward the rear end of the frame 101. This improves the compactness of the piping layout and reduces the steering restrictions on the handlebar 104, thereby maintaining the steering flexibility of the handlebar 104.

[0050] Combine Figure 6 and Figure 7As shown, the first pipe joint 122a and the second pipe joint 122b can be connected through the metal connecting block 123, and the front wheel brake piping structure includes a mounting member 124. The adapter 122 is detachably connected to the headlight bracket 116 through the mounting member 124, so that the disassembly and assembly of the adapter 122 is relatively convenient. It should be noted that the first pipe joint 122a and the second pipe joint 122b can be metal joints or rubber joints, which are not limited here. The mounting member 124 can be a snap-fit ​​member, which fixes the metal connecting block 123 by snap-fitting. The mounting member 124 can also be connected to the metal connecting block 123 by screws, bolts and other fixing members. The connection method between the adapter 122 and the headlight bracket 116 is not limited here.

[0051] In some embodiments, the lamp bracket 116 includes a first connecting portion 116a, a second connecting portion 116b, and a third connecting portion 116c. The first connecting portion 116a and the second connecting portion 116b are connected to the upper connecting plate 113 and the lower connecting plate 114, respectively. The third connecting portion 116c is used to mount the headlight 117. The structure and shape of these connecting portions are not limited herein, as long as they can be used to mount the headlight 117 to the upper connecting plate 113 and the lower connecting plate 114.

[0052] To further enhance piping compactness, a mounting member 124 is attached to the headlight bracket 116 near the stem tube 101a and the upper connecting plate 113. As can be appreciated, the closer the mounting member 124 is to the upper connecting plate 113, the closer it is to the brake cylinder 118 on the handlebar 104, and the shorter the required length of the front hose 120. Accordingly, the closer the mounting member 124 is to the stem tube 101a, the smaller the radius of rotation of the mounting member 124 around the stem tube 101a when the handlebar 104 rotates. This allows the rear hose 121, connected to the mounting member 124, to make only a small deflection around the stem tube 101a, minimizing the amount of piping required for the rear hose 121. Therefore, in this embodiment, the mounting member 124 is connected to the position of the headlight bracket 116 near the faucet pipe 101a and the upper connecting plate 113, which can improve the compactness of the pipe layout and shorten the amount of pipe layout without affecting the steering flexibility of the handlebar 104, thereby saving costs.

[0053] Further, combined with Figure 5 As shown, along a direction parallel to the centerline of the faucet pipe 101a, the distance h from the first pipe joint 122a to the upper connecting plate 113 is 3.5 cm to 5.5 cm, for example, h is 3.5 cm, 3.8 cm, 4.0 cm, 4.5 cm, 5.0 cm, or 5.5 cm. This arrangement can reduce the length of the front hose 120, thereby saving costs.

[0054] The vertical distance d between the second pipe joint 122b and the centerline of the faucet pipe 101a is 3.5 cm to 5.5 cm, for example, d is 3.5 cm, 3.8 cm, 4.0 cm, 4.5 cm, 5.0 cm, or 5.5 cm. This arrangement minimizes the deflection of the rear hose 121 when the handlebar 104 is turned, ensuring flexible steering of the handlebar 104 while reducing the length of the rear hose 121 and saving costs.

[0055] Combine Figure 8 and Figure 9 As shown, a limiter 125 is provided on the rear side of the frame 101 near the faucet pipe 101a, and part of the structure of the rear hose 121 is restrained to the frame 101 through the limiter 125, thereby reducing the friction between the rear hose 121 and the frame 101 to prevent the rear hose 121 from being worn.

[0056] The position limiting member 125 can be a spring buckle for limiting the position of the pipe, or a wire ring. There is no limitation on the structure of the position limiting member 125, as long as it can meet the pipe laying needs.

[0057] Combine Figure 1 、 Figure 10 and Figure 11 As shown, in an embodiment in which the brake piping structure includes piping for rear wheel braking, the vehicle frame 101 includes a main frame 1011 extending from a stem pipe 101a toward the rear of the vehicle body, and a pivot frame 1012 extending from the rear portion of the main frame 1011 toward the bottom of the vehicle body. Pivot frame 1012 is connected to pivot 101b, so that a swing arm 108 is rotatably mounted on pivot 101b. Specifically, swing arm 108 includes a cylindrical portion 108a rotatably mounted on pivot 101b, allowing swing arm 108 to rotate relative to frame 101 about pivot 101b. In this manner, swing arm 108 is supported by pivot 101b and suspended from frame 101 in a freely swingable manner.

[0058] The rear wheel brake piping structure includes brake piping 201 provided to the vehicle frame 101 and the swing arm 108. Brake piping 201 is used to transmit the hydraulic pressure generated by the ABS modulator 202 to the rear brake caliper 203 of the rear wheel 112. In this embodiment, the ABS modulator 202 supplies hydraulic pressure to the rear brake caliper 203 based on the transmitted hydraulic pressure and the vehicle's driving state, thereby controlling the braking of the rear wheel 112. It should be noted that the ABS modulator here is the same concept as the aforementioned ABS unit. In this application, the terms "ABS unit" and "ABS modulator" are used to distinguish between front and rear wheel braking, respectively.

[0059] Combine Figures 10 to 12As shown, a tube fixing portion 108b is provided on the surface of the cylindrical portion 108a. The brake piping 201 includes a free pipe section 201a and a fixed pipe section 201b, which are connected. The free pipe section 201a extends from the ABS modulator 202 toward the pivot 101b and is fixed to the tube fixing portion 108b. This fully utilizes the space above and behind the pivot 101b for piping, making the overall vehicle layout more compact. Furthermore, the free pipe section 201a is positioned as close as possible to the pivot 101b, which limits its range of motion and reduces contact friction or interference with other components. This eliminates the need for numerous stoppers to prevent unwanted contact and interference, thereby reducing the number of stoppers and improving the vehicle's aesthetics.

[0060] In this embodiment, the fixed pipe section 201b is fixed to the swing arm 108. The fixed pipe section 201b extends in a curved manner from the cylindrical portion 108a to the upper surface of the swing arm 108, and is connected to the rear brake caliper 203 from above the swing arm 108. This ensures that the fixed pipe section 201b is relatively fixed to the swing arm 108, and prevents contact wear between the fixed pipe section 201b and the swing arm 108 due to rotation of the swing arm 108 about the pivot 101b. Therefore, the rear wheel brake piping structure of the saddle-type riding vehicle 100 of the present invention can reduce contact friction and interference between the brake pipe 201 and other components, and reduce the use of restrictive components, thereby improving the aesthetic appearance.

[0061] In order to facilitate understanding of the superiority of the rear wheel brake piping structure of the present invention in achieving the above-mentioned effects, a rear wheel brake piping structure in the related art is used as a reference for explanation below.

[0062] For example, Figure 13 In a related art rear wheel brake piping structure shown in FIG, one end of a brake pipe 201 is fixed to a component that does not move relative to the vehicle frame 101 (the vehicle frame 101 itself or a component fixedly assembled thereto), and the other end is fixed to the swing arm 108 that swings the rear wheel 112. As the swing arm 108 rotates about the pivot 101b, the brake pipe 201 moves more widely due to its greater distance from the pivot 101b. During this movement, the brake pipe 201 may come into contact with the swing arm 108, causing wear, and may also interfere with surrounding components of the swing arm 108. To prevent contact and interference, a large number of stoppers are required to limit the position of the brake pipe 201, which restricts the layout of the brake pipe 201.

[0063] In the present invention, the cylindrical portion 108a of the swing arm 108 is provided with a pipe fixing portion 108b, and the free pipe section 201a and the fixed pipe section 201b of the brake pipe 201 are both connected to the pipe fixing portion 108b. Figure 14 and Figure 15As shown, even if the swing arm 108 rotates around the pivot 101b, the movement amplitude of the free tube segment 201a and the fixed tube segment 201b near the pivot 101b is small. To be precise, when the swing arm 108 rotates around the pivot 101b in the first direction to the first extreme position in the normal position, and rotates in the second direction (opposite to the first direction) to the second extreme position, the movement amplitude generated by the free tube segment 201a is small enough to be negligible. Therefore, this small-amplitude movement of the free tube segment 201a is not prone to contact and wear with the swing arm 108, and there is no need to arrange a large number of limiting components, thereby achieving the effect of optimizing the overall appearance.

[0064] In some embodiments, the tube fixing portion 108b is located approximately in the middle of the cylindrical portion 108a. In other words, the tube fixing portion 108b can be located in the center of the cylindrical portion 108a or near the center of the cylindrical portion 108a, as long as the tube fixing portion 108b is located approximately in the center of the cylindrical portion 108a. In this manner, the ABS modulator 202 is positioned on the vehicle frame 101 in the center of the cylindrical portion 108a to maintain the weight balance of the frame 101 in the vehicle width direction. With this structural arrangement, the free section 201a of the brake piping 201 extending from the ABS modulator 202 can be curved to facilitate connection with the tube fixing portion 108b.

[0065] Combine Figure 16 As shown, the outlet directions of the two ends of the free tube section 201a are substantially parallel, giving the free tube section 201a a U-shaped bend. Consequently, when the swing arm 108 rotates about the pivot 101b, the connection between the free tube section 201a and the cylindrical portion 108a rotates slightly. In other words, the portion of the free tube section 201a near the tube fixing portion 108b does not move significantly. Consequently, contact wear and motion interference between the free tube section 201a and the cylindrical portion 108a are significantly reduced, thereby maintaining the stability of the brake pipe 201.

[0066] In some embodiments, when viewed from the front and rear sides of the cylindrical portion 108a, the free tube section 201a is arranged in a sideways U-shape to fully utilize the small space above and behind the pivot 101b.

[0067] It should be noted that in some embodiments, the portion of the free tube section 201a connected to the cylindrical portion 108a extends along the axial direction of the cylindrical portion 108a, or the portion of the free tube section 201a connected to the cylindrical portion 108a extends in a direction that forms a certain angle with the axial direction of the cylindrical portion 108a. For example, the extension direction of the portion of the free tube section 201a connected to the cylindrical portion 108a forms an angle of 10° to 45° with the axial direction of the cylindrical portion 108a. The angle between the two can be 10°, 13°, 20°, 25°, 30°, 35°, 40°, or 45°, which is not limited here.

[0068] See again Figures 10 to 12 As shown, in some embodiments, the rear wheel brake piping structure includes at least one pipe clamp 204. The fixed pipe section 201b is secured to the swing arm 108 via the at least one pipe clamp 204, thereby enhancing the connection stability between the fixed pipe section 201b and the swing arm 108. The number of pipe clamps 204 can be one, two, or three, and the number of pipe clamps 204 is not limited herein. In some embodiments, a pipe clamp 204 is positioned in the middle of the swing arm 108 to stably secure the fixed pipe section 201b to the swing arm 108. After being secured by the pipe clamp 204, the fixed pipe section 201b is connected to the rear brake caliper 203 from above the swing arm 108. This allows the brake piping 201 to be fully utilized above the swing arm 108 for installation, resulting in a compact layout.

[0069] It should be noted that frame tubes and covers can be provided on both sides of the frame 101 to use the covers to shield the free pipe section 201a of the brake pipe 201 to prevent the free pipe section 201a from being observed from the outside of the motorcycle, thereby improving the overall aesthetics.

[0070] In some embodiments, the oil outlet 202a of the ABS modulator 202 is located at the upper rear portion of the cylindrical portion 108a. One end of the free pipe section 201a is connected to the oil outlet 202a, and the other end is connected to the pipe fixing portion 108b. This arrangement allows the free pipe section 201a of the brake piping 201 to be located substantially above and behind the pivot 101b, occupying less space and being close to the pivot 101b. This prevents the free pipe section 201a from significantly moving due to the swing arm 108 rotating about the pivot 101b. Consequently, the free pipe section 201a is more stable, less susceptible to contact and wear with structural components near the pivot 101b, and reduces the likelihood of motion interference.

[0071] In some embodiments, the free tube segment 201a is a flexible tube, so that the free tube segment 201a can adaptively produce flexible deformation when subjected to force to reduce stress. In this way, as the swing arm 108 rotates around the pivot 101b, the free tube segment 201a can produce flexible deformation to reduce the stress generated with the cylindrical portion 108a, thereby maintaining the smoothness of the movement of the swing arm 108.

[0072] In some embodiments, the free pipe section 201a is a rubber hose. In this way, the free pipe section 201a can be maintained in a certain bending shape without setting a limiting component, thereby compensating for the defect that it is not easy to set a limiting component at the free pipe section 201a.

[0073] In some embodiments, the fixed pipe section 201b is formed by a rubber hose, so that the fixed pipe section 201b is easy to bend. Therefore, when the swing arm 108 swings around the pivot 101b, the fixed pipe section 201b fixed to the swing arm 108 will not generate a load that hinders the movement of the swing arm 108, so that the swing arm 108 can swing smoothly around the pivot 101b.

[0074] like Figure 12 As shown, in some embodiments, the tube fixing portion 108b includes a hook and a tube connector 205. The tube connector 205 is fixed to the cylindrical portion 108a via the hook, and the free tube section 201a and the fixed tube section 201b are connected via the tube connector 205. The hook can conveniently connect the tube connector 205 to the cylindrical portion 108a, making it easier to assemble and disassemble the brake pipe 201 and reducing assembly time. In addition, in this embodiment, the free pipe section 201a and the fixed pipe section 201b can be connected together by using the pipe connector 205. On the other hand, the connection between the pipe connector 205 and the pipe fixing portion 108b simultaneously realizes the installation and fixation of the free pipe section 201a and the fixed pipe section 201b. Since the pipe fixing portion 108b is located at the cylindrical portion 108a corresponding to the pivot 101b, during the rotation of the swing arm 108 around the pivot 101b, the free pipe section 201a and the fixed pipe section 201b will not have a large relative displacement relative to the swing arm 108. This is because the closer the object is to the rotation center line of the pivot 101b, the smaller the rotation displacement will be, thereby causing The smaller the relative displacement, in this embodiment, since the connection point between the free pipe section 201a and the fixed pipe section 201b (i.e., the pipe connector 205) is connected to the cylindrical portion 108a via a hook, the free pipe section 201a does not move significantly during the rotation of the swing arm 108 about the pivot 101b, and thus does not wear or interfere with the swing arm 108. Since the fixed pipe section 201b is fixed to the swing arm 108, there is no relative movement between the fixed pipe section 201b and the swing arm 108. During the rotation of the swing arm 108 about the pivot 101b, the fixed pipe section 201b moves with the swing arm 108, thus also avoiding wear or interference. Overall, the rear wheel brake piping structure of the present invention has minimal wear or interference between the brake piping 201 and other components such as the swing arm 108.

[0075] It should be noted that the present invention is not limited to the above-described embodiment.
