[0048] Please refer to the accompanying Figure 2As an implementation manner, the seat tub 18 comprises a seat tub body 181 and a seat cushion 182, the seat tub body 181 is at least partially connected to the frame 11, an internal space of the seat tub body 181 is formed for placing articles such as helmets, and the seat tub body 181 can be rotationally connected with the seat cushion 182, so that the internal space is closed by the seat cushion 182. In the height direction of the motorcycle 100, the seat tub 18 at least partially overlaps the fuel tank 161, and the engine of the motorcycle 100 is arranged below the seat tub 18, so that the capacity of the internal space of the seat tub body 181 is increased by staggered arrangement of the seat tub 18 and the fuel tank 161 while ensuring the capacity of the fuel tank 161.

[0049] Further, the front side of the seat tub body 181 is integrally formed with a seat cushion connecting portion 1811 for connecting with the seat cushion 182, and at least the seat cushion connecting portion 1811 of the seat tub body 181 overlaps the fuel tank 161 in the height direction of the motorcycle.

[0050] As shown in Figure 3 , the front and rear parts of the seat tub body 181 are respectively provided with seat tub fixing holes 1812, the seat tub fixing hole 1812 located at the front part can be arranged at the bottom of the seat tub body 181, the rear side of the seat tub body 181 extends a seat tub fixing lug plate 1813, and the seat tub fixing lug plate 1813 is provided with a seat tub fixing hole 1812; a bolt passes through the seat tub fixing hole 1812 to realize assembly and fixation of the seat tub body 181.

[0051] As shown in Figure 4 , the rear of the seat tub body 181 is provided with a battery box structure 125, and a battery for supplying power to the whole motorcycle is arranged in the battery box structure 125; the battery box structure 125 and the seat tub body 181 share at least one mounting point, so that the length of the vehicle can be further reduced while reducing the mounting points.

[0052] Specifically, the front side of the battery box structure 125 is provided with a battery box mounting hole for fixing the battery box structure 125 and the frame, in the assembly process, a bolt passes through the battery box mounting hole and the seat tub fixing hole 1812 located at the rear part of the seat tub body 181 to simultaneously fix the battery box structure 125 and the seat tub body 181 on the frame 11, so that the assembly process and the number of required components can be reduced while reducing the length of the vehicle, which is beneficial to improve the assembly efficiency and reduce the product cost.

[0053] As shown in Figure 5As shown, in some embodiments, the frame 11 includes a front frame 111, and the suspension system 13 includes a lower connecting plate 131, an inner shock absorber tube 132, and an outer shock absorber tube 133. The lower connecting plate 131 is connected to the front frame 111, the upper part of the inner shock absorber tube 132 is connected to the lower connecting plate 131, the lower part of the inner shock absorber tube 132 is connected to the outer shock absorber tube 133, and the lower part of the outer shock absorber tube 133 is connected to the braking system 17 of the motorcycle 100.

[0054] The walking system 15 includes at least a front wheel 151 and a front axle 152, with the front wheel 151 connected to the shock absorber outer tube 133 via the front axle 152; the braking system 17 includes at least a brake disc 171 and a brake caliper 172 for braking the front wheel 151, with the brake disc 171 at least partially disposed on the front wheel 151 and the brake caliper 172 at least partially disposed on the brake disc 171.

[0055] The braking system 17 also includes a first oil pipe 173, a second oil pipe 174, and a brake control unit 175. The first oil pipe 173 is located between the lower connecting plate 131 and the brake caliper 172. The first oil pipe 173 is fixedly connected to the shock absorber outer tube 133 via a fixed lug 1731, thereby dividing the first oil pipe 173 into a first pipe segment 1732 located between the lower connecting plate 131 and the fixed lug 1731, and a second pipe segment 1733 located between the fixed lug 1731 and the brake caliper 172. The second oil pipe 174 is located between the lower connecting plate 131 and the brake control unit 175. The brake control unit 175 is at least partially connected to the front frame 111. The brake control unit 175 communicates with the brake caliper 172 via the first oil pipe 173 and the second oil pipe 174, thereby enabling control of the brake caliper 172 by controlling the hydraulic fluid.

[0056] The inner shock absorber tube 132 is positioned above the outer shock absorber tube 133, and at least a portion of the inner shock absorber tube 132 is located inside the outer shock absorber tube 133. During motorcycle operation, shock absorption is achieved by the up-and-down movement of the inner shock absorber tube 132 within the outer shock absorber tube 133. In this application, the first oil pipe 173 is fixed to the outer shock absorber tube 133 via a fixing lug 1731, ensuring that the second pipe segment 1733, located between the fixing lug 1731 and the brake caliper 172, remains relatively fixed to the outer shock absorber tube 133. This effectively prevents the up-and-down movement of the motorcycle during operation from affecting the second pipe segment 1733.

[0057] Among them, such as Figure 6 As shown, one end of the fixed support lug 1731 is provided with a bolt hole, and the other end is bent to form a round fixed end. The size of the round fixed end is adapted to the outer diameter of the oil pipe, which facilitates the proper fixing of the oil pipe. While clamping the oil pipe, there will be no compression of the hydraulic oil inside the oil pipe.

[0058] In order to facilitate the installation of the fixing lug 1731, the shock-absorbing outer tube 133 is integrally formed with a lug fixing portion 1331, which can be detachably connected with the fixing lug 1731. For example, the lug fixing portion 1331 is provided with a fixing hole through which a bolt can pass, and in the installation process, the bolt passes through the bolt holes on the fixing lug 1731 and the lug fixing portion 1331 to achieve detachable connection between the fixing lug 1731 and the lug fixing portion 1331. Of course, the lug fixing portion 1331 can also be separately processed and connected with the shock-absorbing outer tube 133 by welding or other fixing methods.

[0059] As shown in Figure 7 The frame 11 includes a front frame 111, and in order to facilitate the connection and fixation of the brake oil pipe, a two-way piece 176 is detachably arranged on the lower connecting plate 131. The two-way piece 176 includes a fixing body 1761 and two connecting pipes 1762, one end of each of the two connecting pipes 1762 is connected with the fixing body 1761, and the other end of each of the two connecting pipes 1762 is in communication with the first oil pipe 173 and the second oil pipe 174.

[0060] Specifically, the fixing body 1761 is provided with a bolt hole for fixing the two-way piece 176 on the lower connecting plate 131, and the fixing body 1761 is fixed with the lower connecting plate 131 by a bolt, and the two connecting pipes 1762 can be bent as needed to facilitate the connection of the first oil pipe 173 and the second oil pipe 174, for example, the two connecting pipes 1762 can be arranged at a right angle or an obtuse angle, and a bending portion can also be arranged on the two connecting pipes 1762.

[0061] Among them, the two-way piece 176 can be made of rigid material, for example, metal material, and the first oil pipe 173 and the second oil pipe 174 can be made of elastic material, for example, rubber; such arrangement not only facilitates the plug-in cooperation of the oil pipe connection end, but also helps to improve the service life of the brake system 17 and adapt to the elastic demand of the brake oil pipe during the steering and driving of the motorcycle.

[0062] Specifically, the first oil pipe 173 can be a hard pipe, and the second oil pipe 174 can be a soft pipe. When the motorcycle needs to steer, the first oil pipe 173 rotates synchronously with the shock-absorbing inner tube 132 and the shock-absorbing outer tube 133, and there is no relative movement between the first oil pipe 173 and the shock-absorbing inner tube 132 and the shock-absorbing outer tube 133. The end of the second oil pipe 174 connected with the brake control unit 175 does not rotate with the rotation of the first oil pipe 173, and the end of the second oil pipe 174 connected with the lower connecting plate 131 rotates with the rotation. Such arrangement, by segmenting the first oil pipe 173 and the second oil pipe 174, reduces the number of mechanisms that follow the relative movement of the steering mechanism during the steering of the motorcycle, thereby reducing the wear of the oil pipe caused by the relative movement.

[0063] Referring to Figure 8 The lower connecting plate 131 is connected with the front frame 111, and the vehicle body cover 12 further comprises a front mudguard 123 arranged at the front side of the motorcycle, the front mudguard 123 is detachably connected with the lower connecting plate 131, and the front mudguard 123 is provided with an avoiding opening 1231, which is configured to allow at least a part of the front frame 111 of the motorcycle to pass through.

[0064] In order to avoid the entry of sand into the interior of the front mudguard 123 during use, and at the same time improve the aesthetic appearance of the motorcycle, the front mudguard 123 further comprises a cover plate 1232, which is detachably connected with the front mudguard 123 and can at least partially close the avoiding opening 1231.

[0065] Specifically, the cover plate 1232 comprises a cover plate body 1232a, a cover plate connecting lug 1232b and an avoiding groove 1232c, the cover plate connecting lug 1232b extends outward from the cover plate body 1232a, and the cover plate connecting lug 1232b is configured to have two, and the avoiding groove 1232c is formed between the two cover plate connecting lugs 1232b. The avoiding groove 1232c can allow the connecting pipe 1762 to pass through, thereby realizing hydraulic communication between the first oil pipe 173 and the second oil pipe 174.

[0066] As shown in Figure 8 and Figure 9 , the front mudguard 123 at least covers the first pipe segment 1732, and in the front view of the motorcycle, the front mudguard 123 completely covers the first pipe segment 1732, so that the first pipe segment 1732 is in an invisible state. By covering the first pipe segment 1732 with the front mudguard 123, the brake oil pipe can be prevented from being exposed to the outside of the motorcycle during use of the motorcycle; such an arrangement is beneficial to slow down the aging of the oil pipe and improve the service life of the oil pipe.

[0067] As shown in Figure 10 , in order to facilitate assembly and fixation between the front mudguard 123 and the lower connecting plate 131, the front mudguard 123 further comprises a front mudguard fixing bracket 1233, the front mudguard fixing bracket 1233 comprises a first fixing plate 1233a and a second fixing plate 1233b, the first fixing plate 1233a abuts against the lower connecting plate 131, and the second fixing plate 1233b extends forward from the first fixing plate 1233a, wherein at least one front mudguard fixing hole is arranged on the first fixing plate 1233a, and at least one cover plate fixing hole is arranged on the second fixing plate 1233b. Preferably, the second fixing plate 1233b can be provided with two, and the two second fixing plates 1233b correspond to the two cover plate connecting lugs 1232b respectively, thereby realizing fixed connection of the cover plate 1232.

[0068] In summary, in the motorcycle provided in the application, the first oil pipe 173 is divided into the first pipe segment 1732 located between the lower connecting plate 131 and the fixed lug 1731 and the second pipe segment 1733 located between the fixed lug 1731 and the brake caliper 172 by the fixed lug 1731. Among them, the front mudguard 123 covers at least the first pipe segment 1732, and in the front view of the motorcycle, the front mudguard 123 completely covers the first pipe segment 1732, so that the first pipe segment 1732 is in an invisible state; thereby effectively avoiding the brake oil pipe from being exposed to the outside of the motorcycle and being attacked by wind and sand during use of the motorcycle, which is conducive to slowing down the aging of the brake oil pipe and improving the service life of the brake oil pipe.

[0069] Please refer to the accompanying drawings Figure 11 As an implementation manner, the frame 11 comprises a front frame 111 and a rear frame 112, wherein the front frame 111 is provided with a head tube 1111 in a tubular shape on the upper part of the front side, the rear frame 112 is connected with the front frame 111, and the frame is basically left-right symmetrical based on the axis. The rear frame 112 comprises a front support 1121, a bottom support 1122 and a rear support 1123 connected in sequence, wherein the upper part of the front support 1121 is connected with the front frame 111, the lower part of the front support 1121 extends downward and rearward, and the bottom support 1122 extends horizontally rearward; the rear support 1123 extends upward and rearward; the end parts of the left rear support 1123 and the right rear support 1123 are connected through a tail cross beam 113, so that one end of the left rear support 1123 and the right rear support 1123 forms a closed ring, and the tail part of the frame 11 is closed, which is more conducive to increasing the overall strength and rigidity of the frame 11.

[0070] Further, the left rear frame 112 and the right rear frame 112 are respectively provided with pedal support longitudinal beams 1124, the foot pedal 121 is installed on the pedal support longitudinal beams 1124, and the pedal support longitudinal beams 1124 support the foot pedal 121; at the same time, the pedal support longitudinal beams 1124 arranged on the rear frame 112 are also conducive to strengthening the longitudinal rigidity of the frame 11. Preferably, a plurality of weight reduction holes are arranged on the pedal support longitudinal beams 1124, which can improve the rigidity of the frame 11 and reduce the weight of the frame 11.

[0071] Specifically, the two ends of the pedal support longitudinal beam 1124 are respectively fixed with the front support 1121 and the rear support 1123. Preferably, the two ends of the pedal support longitudinal beam 1124 are respectively fixed with the middle and lower parts of the front support 1121 and the rear support 1123, so as to support and fix the foot pedal 121.

[0072] In order to facilitate assembly and fixation, the pedal support longitudinal beam 1124 is fixed with the rear frame 112 through the pedal mounting bracket 1125. The pedal mounting bracket 1125 includes a pedal mounting bracket body 1125a and a support pipe 1125b, the bottom of the pedal mounting bracket body 1125a is fixedly connected with the rear frame 112, and the support pipe 1125b is located at the upper part of the pedal mounting bracket body 1125a. The support pipe 1125b is a metal pipe with a circular cross section, and the bottom of the pedal support longitudinal beam 1124 is provided with a circular arc-shaped groove matched with the support pipe 1125b. The pedal mounting bracket 1125 is distributed on both sides of the pedal support longitudinal beam 1124, so as to realize the support and fixation of the pedal support longitudinal beam 1124 through the pedal mounting bracket 1125.

[0073] Further, in another embodiment, an oil tank bracket 114 for supporting the bottom of the oil tank 161 is arranged between the left rear frame 112 and the right rear frame 112. The oil tank bracket 114 can be arranged in a U-shaped structure, for example, and the open ends of the U-shaped structure are fixedly connected with the left bottom bracket 1122 and the right bottom bracket 1122, respectively. During assembly, the bottom of the U-shaped structure abuts against the bottom of the oil tank 161, so as to realize the support of the bottom of the oil tank 161 through the oil tank bracket 114. Such an arrangement is advantageous for further improving the stability of the oil tank 161.

[0074] As shown in FIG. 1, Figure 11 The first cross beam 115 is arranged at the end of the bottom bracket 1122 away from the front bracket 1121, and the end of the rear bracket 1123 close to the bottom bracket 1122 is connected with the first cross beam 115, so as to realize the connection between the bottom bracket 1122 and the rear bracket 1123 through the first cross beam 115. The first cross beam 115 can be a tubular structure with a circular cross section, for example. Arranging the first cross beam 115 at the bottom of the left rear frame 112 and the right rear frame 112 is advantageous for further improving the lateral stiffness of the frame 11.

[0075] Further, the width between the left bottom bracket 1122 and the right bottom bracket 1122 is greater than the width between the left rear bracket 1123 and the right rear bracket 1123. Such an arrangement can provide a larger accommodation space for the oil tank 161 while maintaining the overall streamline structure of the motorcycle, so as to guarantee the cruising range of the motorcycle.

[0076] In order to further improve the strength and stiffness of the rear frame 112, the left rear bracket 1123 and the right rear bracket 1123 are further respectively provided with a bent portion, and a reinforcing rib 1126 fixedly connected with the rear bracket 1123 is arranged inside the bent portion.

[0077] As shown in FIG. 1, Figure 11As shown, the rear frame 112 is further provided with a front seat bucket support cross beam 1128 and a rear seat bucket support cross beam 1129, wherein the front seat bucket support cross beam 1128 and the rear seat bucket support cross beam 1129 are respectively used for fixing the front and rear portions of the seat bucket 121 of the motorcycle.

[0078] The front seat bucket support cross beam 1128 is arranged in a U shape, and the open ends of the U shape are fixedly connected to the rear supports 1123 on one side of the front frame 111, respectively. Preferably, the open ends of the U shape are arranged at an acute angle or substantially perpendicularly with the rear supports 1123 to realize the support of the seat bucket 121. A triangular reinforcing member 1128a is further arranged between the front seat bucket support cross beam 1128 and the rear supports 1123, and the two sides of the reinforcing member 1128a are welded and fixed to the front seat bucket support cross beam 1128 and the rear supports 1123, respectively.
