Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0045] This application provides, as follows: Figure 1 The motorcycle 100 shown includes a frame 11, body panels 12, suspension system 13, power system 14, running system 15, fuel system 16, braking system 17, and seat 18.

[0046] The body panel 12 includes a foot pedal 121 and at least partially covers the frame 11; the running system 15 is at least partially disposed below the frame 11, and the suspension system 13 is used to connect the running system 15 to the frame 11; the power system 14 is at least partially supported by the frame 11 and is used to drive the running system 15; the fuel system 16 is at least partially supported by the frame 11 and is used to supply fuel to the power system, and the fuel system 16 includes a fuel tank 161 located below the foot pedal 121; the braking system 17 is at least partially connected to the running system 15 and is used to brake the running system 15; and the seat bucket 18 is supported by the frame 11 and forms a storage space.

[0047] To clearly illustrate the technical solution of the application, the following are also defined: Figure 1 The directions shown are front, back, left, right, up, and down. In this application, the directions defined are front, back, left, right, up, and down when the motorcycle 100 is on a horizontal ground; the length direction of the motorcycle 100 refers to the aforementioned front-back direction, the width direction of the motorcycle 100 refers to the aforementioned left-right direction, and the height direction of the motorcycle 100 refers to the aforementioned up-down direction.

[0048] Please see the appendix Figure 2As one implementation, the seat bucket 18 includes a seat bucket body 181 and a seat cushion 182. The seat bucket body 181 is at least partially connected to the frame 11. The interior of the seat bucket body 181 forms a storage space for storing items such as helmets. The seat bucket body 181 can be rotatably connected to the seat cushion 182, thereby enclosing the storage space through the seat cushion 182. Viewed along the height direction of the motorcycle 100, the seat bucket 18 at least partially overlaps with the fuel tank 161. The engine of the motorcycle 100 is located below the seat bucket 18. By staggering the seat bucket 18 and the fuel tank 161, the capacity of the fuel tank 161 is maintained while increasing the volume of the storage space inside the seat bucket body 181.

[0049] Furthermore, a seat connection portion 1811 for connecting with the seat cushion 182 is integrally formed on the front side of the seat body 181. When viewed along the height direction of the motorcycle, at least the seat connection portion 1811 of the seat body 181 overlaps with the fuel tank 161.

[0050] like Figure 3 As shown, the front and rear parts of the toilet body 181 are respectively provided with toilet fixing holes 1812. The toilet fixing hole 1812 located at the front can be set at the bottom of the toilet body 181. A toilet fixing ear plate 1813 extends from the rear side of the toilet body 181, and the toilet fixing ear plate 1813 is provided with toilet fixing holes 1812. Bolts pass through the toilet fixing holes 1812 to assemble and fix the toilet body 181.

[0051] like Figure 4 As shown, a battery box structure 125 is provided at the rear of the seat bucket body 181. The battery box structure 125 houses a battery that powers the entire motorcycle. The battery box structure 125 shares at least one mounting point with the seat bucket body 181, thereby reducing the number of mounting points and further reducing the length of the vehicle.

[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 to the frame. During assembly, bolts pass through the battery box mounting hole and the seat bucket fixing hole 1812 located at the rear of the seat bucket body 181 to simultaneously fix the battery box structure 125 and the seat bucket body 181 to the frame 11. This reduces the length of the vehicle while reducing the number of assembly steps and required parts, which is beneficial to improving assembly efficiency and reducing product costs.

[0053] like 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] To facilitate the installation of the fixed lug 1731, a lug fixing part 1331 is integrally formed on the shock-absorbing outer tube 133, which can be detachably connected to the fixed lug 1731. For example, the lug fixing part 1331 is provided with fixing holes for bolts to pass through. During installation, bolts pass through the bolt holes on the fixed lug 1731 and the lug fixing part 1331 to achieve a detachable connection between the fixed lug 1731 and the lug fixing part 1331. Of course, the lug fixing part 1331 can also be processed separately and connected to the shock-absorbing outer tube 133 by welding or other fixing methods.

[0059] like Figure 7 As shown, the frame 11 includes a front frame 111. To facilitate the connection and fixation of the brake lines, a two-way connector 176 is detachably provided on the lower connecting plate 131. The two-way connector 176 includes a fixed body 1761 and two connecting pipes 1762. One end of each connecting pipe 1762 is connected to the fixed body 1761, and the other end of each connecting pipe 1762 is connected to the first oil pipe 173 and the second oil pipe 174, respectively.

[0060] Specifically, the fixing body 1761 is provided with bolt holes for fixing the two connecting parts 176 to the lower connecting plate 131. The fixing body 1761 is fixed to the lower connecting plate 131 by bolts. 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 set at right angles or obtuse angles, and the two connecting pipes 1762 can also be provided with bends.

[0061] Among them, the two connecting parts 176 can be made of rigid materials, such as metal, while the first oil pipe 173 and the second oil pipe 174 can be made of elastic materials, such as rubber. This arrangement facilitates the insertion and mating of the oil pipe connection ends, while also improving the service life of the braking system 17 and meeting the elasticity requirements of the brake oil pipe during motorcycle steering and driving.

[0062] Specifically, the first oil pipe 173 can be a rigid pipe, and the second oil pipe 174 can be a flexible pipe. When the motorcycle needs to turn, the first oil pipe 173 rotates synchronously with the inner shock absorber pipe 132 and the outer shock absorber pipe 133, with no relative movement between them. The end of the second oil pipe 174 connected to the brake control unit 175 does not rotate with the rotation of the first oil pipe 173, while the end of the second oil pipe 174 connected to the lower connecting plate 131 rotates with it. This arrangement, by segmenting the first oil pipe 173 and the second oil pipe 174, reduces the number of mechanisms that move relative to the steering mechanism during motorcycle turning, thereby reducing wear on the oil pipes due to relative movement.

[0063] Please see Figure 8 The lower connecting plate 131 is connected to the front frame 111. The body panel 12 also includes a front fender 123 disposed on the front side of the motorcycle. The front fender 123 is detachably connected to the lower connecting plate 131. The front fender 123 is provided with a clearance opening 1231, which is configured to allow at least a portion of the front frame 111 of the motorcycle to pass through.

[0064] To prevent mud and sand from entering the front fender 123 during use and to improve the aesthetics of the motorcycle, the front fender 123 also includes a cover plate 1232. The cover plate 1232 is detachably connected to the front fender 123 and can at least partially close the avoidance opening 1231.

[0065] Specifically, the cover plate 1232 includes a cover plate body 1232a, a cover plate connecting ear 1232b, and a clearance groove 1232c. The cover plate connecting ear 1232b extends outward from the cover plate body 1232a, and two cover plate connecting ears 1232b are configured to form a clearance groove 1232c between the two cover plate connecting ears 1232b. The clearance groove 1232c allows the connecting pipe 1762 to pass through, thereby realizing hydraulic communication between the first oil pipe 173 and the second oil pipe 174.

[0066] like Figure 8 and Figure 9 As shown, the front fender 123 at least covers the first pipe section 1732, and in the front view of the motorcycle, the front fender 123 completely covers the first pipe section 1732, making the first pipe section 1732 invisible. By covering the first pipe section 1732 with the front fender 123, the brake lines are prevented from being exposed to the outside of the motorcycle during use; this arrangement helps to slow down the aging of the brake lines and improve their service life.

[0067] like Figure 10 As shown, to facilitate the assembly and fixing of the front fender 123 and the lower connecting plate 131, the front fender 123 further includes a front fender fixing bracket 1233. The front fender fixing bracket 1233 includes 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. The first fixing plate 1233a has at least one front fender fixing hole, and the second fixing plate 1233b has at least one cover plate fixing hole. Preferably, two second fixing plates 1233b can be provided, with each second fixing plate 1233b corresponding to one of the two cover plate connecting ears 1232b, thereby achieving a fixed connection of the cover plate 1232.

[0068] In summary, in the motorcycle provided by this application, the first oil pipe 173 is divided into a first pipe segment 1732 located between the lower connecting plate 131 and the fixed support 1731, and a second pipe segment 1733 located between the fixed support 1731 and the brake caliper 172 by the fixed support lug 1731. The front fender 123 at least covers the first pipe segment 1732, and in the front view of the motorcycle, the front fender 123 completely covers the first pipe segment 1732, making the first pipe segment 1732 invisible. This effectively prevents the brake pipe from being exposed to the outside of the motorcycle and subjected to wind and sand during use, thus slowing down the aging of the brake pipe and increasing its service life.

[0069] Please see the appendix Figure 11 As one implementation, the frame 11 includes a front frame 111 and a rear frame 112. The front frame 111 has a tubular head tube 1111 supported on its upper front side. The rear frame 112 is connected to the front frame 111, and the frames are arranged approximately symmetrically about their central axis. The rear frame 112 includes a front support 1121, a bottom support 1122, and a rear support 1123 connected in sequence. The upper part of the front support 1121 is connected to the front frame 111, and the lower part of the front support 1121 extends downward and backward. The bottom support 1122 extends horizontally and backward. The rear support 1123 extends upward and backward. The ends of the left and right rear supports 1123 are connected by a rear crossbeam 113, forming a closed loop at one end of each support. This closed arrangement of the frame 11 at the rear increases the overall strength and rigidity of the frame 11.

[0070] Furthermore, pedal support longitudinal beams 1124 are respectively provided on the left and right rear frames 112, and the foot pedals 121 are mounted on the pedal support longitudinal beams 1124, which provide support for the foot pedals 121. Simultaneously, the pedal support longitudinal beams 1124 on the rear frames 112 also help to enhance the longitudinal stiffness of the frame 11. Preferably, the pedal support longitudinal beams 1124 are also provided with several weight-reducing holes, which can reduce the weight of the frame 11 while improving its stiffness.

[0071] Specifically, the two ends of the pedal support beam 1124 are fixed to the front bracket 1121 and the rear bracket 1123, respectively. Preferably, the two ends of the pedal support beam 1124 are fixed to the lower middle part of the front bracket 1121 and the rear bracket 1123, respectively, thereby supporting and fixing the foot pedal 121.

[0072] For ease of assembly and fixation, the pedal support longitudinal beam 1124 is mounted and fixed to the rear frame 112 via pedal mounting brackets 1125. The pedal mounting bracket 1125 includes a pedal mounting bracket body 1125a and a support tube 1125b. The bottom of the pedal mounting bracket body 1125a is fixedly connected to the rear frame 112, and the support tube 1125b is located at the upper part of the pedal mounting bracket body 1125a. The support tube 1125b is a metal tube with a circular cross-section, and the bottom of the pedal support longitudinal beam 1124 has an arc-shaped groove that matches the support tube 1125b. The pedal mounting brackets 1125 are distributed on both sides of the pedal support longitudinal beam 1124, thereby providing support and fixation for the pedal support longitudinal beam 1124.

[0073] Furthermore, in another embodiment, a fuel tank bracket 114 for supporting the bottom of the fuel tank 161 is provided between the left and right rear frame 112. The fuel tank bracket 114 can be, for example, U-shaped, with the open ends of the U-shape fixedly connected to the left and right base brackets 1122, respectively. During assembly, the bottom of the U-shape abuts against the bottom of the fuel tank 161, thereby supporting the bottom of the fuel tank 161 through the fuel tank bracket 114. This arrangement helps to further improve the stability of the fuel tank 161.

[0074] like Figure 11 As shown, a first crossbeam 115 is provided at the end of the bottom bracket 1122 away from the front bracket 1121, and the end of the rear bracket 1123 near the bottom bracket 1122 is connected to the first crossbeam 115, thus connecting the bottom bracket 1122 and the rear bracket 1123. The first crossbeam 115 can be, for example, a tubular structure with a circular cross-section. Providing the first crossbeam 115 at the bottom of the left and right rear frames 112 helps to further improve the lateral stiffness of the frame 11.

[0075] Furthermore, the width between the left and right base brackets 1122 is greater than the width between the left and right rear brackets 1123. This arrangement, while maintaining the overall streamlined structure of the motorcycle, provides more space for the fuel tank 161, thereby ensuring the motorcycle's range.

[0076] To further improve the strength and rigidity of the rear frame 112, the left and right rear brackets 1123 are respectively provided with bending parts, and reinforcing ribs 1126 are provided on the inner side of the bending parts and fixedly connected to the rear brackets 1123.

[0077] like Figure 11As shown, the rear frame 112 is also provided with a front seat bucket support crossbeam 1128 and a rear seat bucket support crossbeam 1129, wherein the front seat bucket support crossbeam 1128 and the rear seat bucket support crossbeam 1129 are used to fix the front and rear of the motorcycle seat bucket 121, respectively.

[0078] The front seat bucket support beam 1128 is U-shaped, with the open end of the U fixedly connected to one side of the rear bracket 1123 near the front frame 111. Preferably, the open end of the U-shape is at an acute angle or substantially perpendicular to the rear bracket 1123 to support the seat bucket 121. A triangular reinforcing member 1128a is also provided between the front seat bucket support beam 1128 and the rear bracket 1123. The two sides of the reinforcing member 1128a are welded and fixed to the front seat bucket support beam 1128 and the rear bracket 1123, respectively. This arrangement helps to further improve the support strength of the front seat bucket support beam 1128.

[0079] The two ends of the rear seat bucket support beam 1129 are fixed to the left rear bracket 1123 and the right rear bracket 1123, respectively. Specifically, the two ends of the rear seat bucket support beam 1129 are fixed to the ends of the left rear bracket 1123 and the right rear bracket 1123 near the tail beam 113, respectively. For example, the rear seat bucket support beam 1129 can be fixed to the rear bracket 1123 by welding, bolting, or by setting a mounting bracket. In this embodiment, the specific fixing method is not limited.

[0080] Optionally, a front seat bucket bracket 1128b and a rear seat bucket bracket 1129a are welded and fixed to the front seat bucket support beam 1128 and the rear seat bucket support beam 1129, respectively. The front seat bucket bracket 1128b may be provided with bolt holes for fixing the seat bucket.

[0081] like Figure 11 As shown, the ends of the left and right rear brackets 1123 are connected by the tail crossbeam 113, thereby forming a battery box receiving cavity between the tail crossbeam 113 and the rear seat bucket support crossbeam 1129. After the battery box is installed, the tail crossbeam 113 and the rear bracket 1123 located on the outside of the battery box can effectively reduce the damage that external impacts may cause to the battery box, thereby improving the safety of electrical components.

[0082] Furthermore, such as Figure 12As shown, in another embodiment, the power system 14 includes at least an engine 141 and a gearbox 142, which are connected in transmission; the frame 11 also includes an engine mounting bracket 117, one side of which is connected to the first crossbeam 115, and the other side of which is connected to the engine 141; an engine anti-collision guard plate 1171 is provided at the bottom of the engine mounting bracket 117.

[0083] Specifically, such as Figure 13 As shown, the engine mounting bracket 117 includes a first crossbar 1172 and a second crossbar 1173. The first crossbar 1172 and the second crossbar 1173 are connected by at least two mounting arms 1174. The first crossbar 1172 is welded and fixed to the first crossbeam 115 through multiple ribs. The two ends of the second crossbar 1173 are respectively connected to the engine 141. The engine anti-collision guard plate 1171 is respectively set at the bottom of the two mounting arms 1174 and welded and fixed to the bottom of the mounting arms 1174.

[0084] The engine anti-collision guard plate 1171 includes a guard plate body 1171a and an ear portion 1171b; the guard plate body 117a is welded to the bottom of the engine mounting bracket 117; the ear portion 1171b extends outward from the guard plate body 1171a to the bottom of the engine 141.

[0085] The engine bumper guard 1171 is a one-piece stamped part, and the number of engine bumper guards 1171 corresponds to the number of mounting arms 1174. For example, when there are two mounting arms 1174, the two engine bumper guards 1171 are welded to the bottom of the mounting arms 1174 in a basically symmetrical manner. During vehicle operation, this effectively prevents the engine mounting arms 1174 from colliding with obstacles, thus protecting the engine.

[0086] Furthermore, a lifting bracket 1127 is provided on the left rear bracket 1123 and the right rear bracket 1123 respectively. The lifting bracket 1127 is fixedly connected to the gearbox 142, thereby achieving the installation and fixation of the power system 14 through the lifting bracket 1127 and the engine mounting bracket 116.

[0087] To facilitate the assembly and fixing of the fuel tank 161, such as Figure 13 As shown, a second crossbeam 116 is provided between the left bottom bracket 1122 and the right bottom bracket 1122. The second crossbeam 116 is located on the side of the bottom bracket 1122 near the front bracket 1121. A front mounting bracket 1161 for the fuel tank is fixedly installed on the second crossbeam 116. The front mounting bracket 1161 for the fuel tank is provided with fixing holes for fixing the fuel tank 161.

[0088] The left and right bottom brackets 1122, the first crossbeam 115 and the second crossbeam 116 together form a receiving cavity for accommodating the fuel tank 161, and at least a part of the fuel tank 161 is located in the receiving cavity. By setting the first crossbeam 115 and the second crossbeam 116 at the rear and front of the fuel tank 161 respectively, it is beneficial to strengthen the lateral stiffness of the frame and disperse the lateral stress at the bottom of the frame 11, thereby achieving the purpose of buffering the frame stress and strengthening the lateral stiffness of the frame.

[0089] In summary, in the motorcycle provided by this application, the left and right rear frames 112 form a closed ring structure through the rear crossbeam 114, which helps to increase the overall strength and rigidity of the frame. By setting the first crossbeam 115 and the second crossbeam 116 at the rear and front of the fuel tank 161, it is beneficial to strengthen the lateral rigidity of the frame 11 and disperse the lateral stress at the bottom of the frame, thereby achieving the purpose of buffering the frame stress and strengthening the lateral rigidity of the frame.

[0090] Please see the appendix Figure 14 and Figure 15 In some embodiments, a rear grab handle structure 118 is also installed at the rear of the frame 11. The rear grab handle structure 118 includes a grab handle 1181, a tail box mounting bracket 1182, and a frame connecting part 1183. The grab handle 1181 includes a left grab handle and a right grab handle that are basically symmetrically arranged. One end of the two grab handles 1181 is provided with a frame connecting part 1183, which is connected to the rear of the frame 11. The tail box mounting bracket 1182 is a semi-closed structure with an opening at one end, and the open end is connected to the end of the two grab handles 1181 away from the frame connecting part 1183. The tail box mounting bracket 1182 is provided with at least one tail box mounting part for mounting a tail box. In the height direction of the motorcycle body, the tail box mounting part is lower than the frame connecting part 1183.

[0091] Specifically, such as Figure 14 As shown, the width of the rear grab handle structure 118 gradually decreases along the length of the vehicle body. The grab handle 1181 is installed on the outside of the frame 11, that is, the grab handle 1181 and the tail box mounting bracket 1182 surround the outer periphery of the motorcycle seat 182, so that while making it easy for the rider to grip, it can also effectively protect the seat 182 located inside the rear grab handle structure 118.

[0092] Optionally, the armrest 1181 and the tailgate mounting bracket 1182 are integrally formed tubular structures with a circular cross-section, which facilitates processing and further reduces costs.

[0093] The rear armrest structure 118 also includes a first reinforcing part 1184, which is located on the side of the armrest 1181 away from the frame connection part 1183. The two ends of the first reinforcing part 1184 are respectively connected to the two armrests 1181. By providing the first reinforcing part 1184 between the two armrests 1181, the lateral stiffness of the rear armrest structure 118 can be effectively improved, enhancing the protection of the vehicle body panel 12.

[0094] Furthermore, the rear grab handle structure 118 also includes at least one second reinforcing part 1185, which extends along the length of the vehicle body, and both ends of the second reinforcing part 1185 are connected to the first reinforcing part 1184 and the tailgate mounting bracket 1182, respectively. Preferably, there may be two second reinforcing parts 1185, which are arranged substantially parallel to each other, and the second reinforcing parts 1185 and the tailgate mounting bracket together constitute the tailgate support platform. The first reinforcing part 1184 and the second reinforcing part 1185 may be tubular components with a circular cross-section.

[0095] To facilitate the installation of the tailgate, the tailgate mounting bracket 1182 is provided with at least one tailgate fixing hole, through which the tailgate is fixedly connected to the tailgate mounting bracket 1182. Preferably, two tailgate fixing holes can be provided, with the two tailgate fixing holes located on the tubular structures on both sides of the tailgate mounting bracket 1182. Alternatively, one tailgate fixing hole can be provided, located in the middle of the first reinforcing part. Preferably, a tailgate fixing bracket can also be provided between the two second reinforcing parts 1185, with the tailgate fixing bracket fixedly connected to the second reinforcing parts 1185, and the tailgate fixing hole is provided on the tailgate fixing bracket. The tailgate fixing hole can also be provided in other positions to facilitate the installation of the tailgate, which will not be elaborated further in this application.

[0096] like Figure 15 As shown, to facilitate the installation of the tail box, the handlebars 1181 and the tail box mounting bracket 1182 extend in a basically Z-shape in the direction of the motorcycle's forward movement. Specifically, each handlebar 1181 includes a first segment 1181a, a second segment 1181b, and a third segment 1181c connected in sequence. The first segment 1181a and the second segment 1181b both extend rearward and upward relative to the horizontal plane. The upward tilt angle of the second segment 1181b relative to the horizontal plane is smaller than the upward tilt angle of the first segment 1181a. The third segment 1181c is connected to the second segment 1181b by an arc transition. After the arc bend, the third segment 1181c extends downward and rearward until it connects with the tail box mounting bracket 1182.

[0097] Optionally, the tailgate mounting bracket 1182 has a support recess 1182a for facilitating the support of the tailgate. During tailgate installation, at least a portion of the bottom of the tailgate abuts against the support recess 1182a.

[0098] Please see the appendix Figure 16 and Figure 17 As one implementation, the motorcycle 100 also includes a center stand structure 119 that supports the motorcycle during parking. The center stand structure 119 includes a center stand footrest bracket 1191 and a mounting tube 1192 for rotatably connecting with the frame 11. The center stand footrest bracket 1191 and the mounting tube 1192 are fixedly connected by a first stamping member 1193 and a second stamping member 1194. Connecting the mounting tube 1192 and the center stand footrest bracket 1191 by the first stamping member 1193 and the second stamping member 1194 can reduce the number of connecting components and shorten the welding length in the manufacturing process, thereby helping to reduce the processing and manufacturing cost of the product.

[0099] Specifically, the central support foot bracket 1191 includes an integrally formed support tube 1191a, which is arranged in an inverted U-shape and includes a crossbeam located in the middle and support feet that bend outward from both ends of the crossbeam. The first stamped part 1193 and the second stamped part 1194 are fixedly connected to the crossbeam by welding.

[0100] To improve the support strength of the central support structure 119, the cross sections of the crossbeam, mounting tube 1192, first stamped part 1193, and second stamped part 1194 are basically arranged in a triangular shape. Specifically, the first stamped part 1193 and the second stamped part 1194 are welded and fixed to the mounting tube 1192 and the central support foot bracket 1191, respectively.

[0101] Optionally, such as Figure 18 As shown, the first stamping part 1193 includes a first body 1193a and a first bent portion 1193b extending outward from both ends of the first body 1193a. At least a portion of the first bent portion 1193b is welded and fixed to the central support foot bracket 1191. The first body 1193a, the first bent portion 1193b and the central support foot bracket 1191 form a receiving cavity that can accommodate the second stamping part 1194.

[0102] To further increase the contact area between the first bending portion 1193b and the central support foot bracket 1191, the first bending portion 1193b is also provided with support legs extending from the first bending portion 1193b to both sides, and at least a portion of the support legs are welded and fixed to the central support foot bracket 1191.

[0103] The second stamping part 1194 includes a second body 1194a and second bent portions 1194b extending outward from both ends of the second body 1194a. The ends of the second bent portions 1194b abut against the inner surface of the first body 1193a; that is, the first bent portions 1193b and the second bent portions 1194b are staggered between the first body 1193a and the second body 1194a. The staggered first bent portions 1193b and the second bent portions 1194b form multiple support walls between the first body 1193a and the second body 1194a, which helps to improve the structural strength of the stamping assembly.

[0104] Furthermore, the first stamping part 1193 also has a groove 1193c located on the first body 1193a, and the groove 1193c and the first body 1193a are connected by an arc; a first mounting hole is provided at the bottom of the groove 1193c; and a second mounting hole matching the first mounting hole is provided on the second stamping part 1194.

[0105] To further improve the support strength of the support tube 1191a, an arc-shaped reinforcing member 1191b is provided at the bend between the crossbeam and the support foot. The arc-shaped reinforcing member 1191b is welded and fixed to the inner side of the support tube 1191a.

[0106] The central support foot pedal bracket 1191 also includes a support rod 1191c, which is connected to the support foot. A rib plate 1191d is provided at the angle formed by the support foot and the support rod 1191c.

[0107] In summary, in the motorcycle provided by this application, the fixed connection between the center stand footrest bracket 181 and the mounting tube 182 is achieved by stamping components, which can reduce the number of connecting components and shorten the welding length in the manufacturing process, thereby helping to reduce the processing and manufacturing cost of the product.

[0108] Please see the appendix Figure 19 As one implementation, the fuel system 16 includes a fuel tank 161, which is located below the foot pedal 121. In a top view of the motorcycle, the fuel tank 161 is located between the left and right base brackets 1122. Thus, the base brackets 1122 on both sides of the fuel tank 161 can resist impacts from the sides of the motorcycle, effectively ensuring the safety of the fuel tank 161 during use.

[0109] To facilitate the assembly of the fuel tank 161, a fixing part 1611 for securing it to the frame 11 is provided on the fuel tank 161. Specifically, a first fixing part 1611a and a second fixing part 1611b for securing to the base bracket 1122 are respectively provided on the rear sides of the fuel tank 161. Preferably, the first fixing part 1611a and the second fixing part 1611b are arranged substantially symmetrically with respect to the center lines of the left and right rear frames 112. A third fixing part 1611c and a fourth fixing part 1611d for securing to the rear frame 112 are provided on the front side of the fuel tank 161. Preferably, the third fixing part 1611c and the fourth fixing part 1611d are arranged substantially symmetrically with respect to the center lines of the left and right rear frames 112. Thus, by positioning the fuel tank 161 at four points on both sides and the front, the stability of the fuel tank 161 during use is improved. Among them, the first fixing part 1611a, the second fixing part 1611b, the third fixing part 1611c and the fourth fixing part 1611d can be bolt holes, for example, and the bolts pass through the bolt holes to fix the oil tank 161 during the assembly process.

[0110] Among them, such as Figure 20 As shown, the fuel tank 161 includes an upper tank body 1612, a lower tank body 1613, and a connecting flange 1614, wherein the upper tank body 1612 and the lower tank body 1613 are joined by the connecting flange 1614. A first fixing part 1611a, a second fixing part 1611b, a third fixing part 1611c, and a fourth fixing part 1611d are provided on the connecting flange 1614.

[0111] Looking along the height of the motorcycle, such as Figure 13 As shown, the lower housing 1613 does not overlap with the rear frame 112 located on both sides. That is to say, the external dimension of the lower housing 1613 in the width direction of the motorcycle is smaller than the distance between the left and right base brackets 1122. During the installation of the fuel tank 161, the lower housing 1613 can be completely accommodated in the receiving cavity, thereby further ensuring the volume of the fuel tank 161 without increasing the height of the foot pedal 121.

[0112] like Figure 20 As shown, viewed along the width of the motorcycle, the rear frame 112 overlaps with the fuel tank 161. That is, in the height direction of the motorcycle, both the left and right base brackets 1122 are located between the upper and lower surfaces of the fuel tank 161. Simultaneously, since the lower housing 1613 is located within the receiving cavity, the base brackets 1122 on both sides are positioned on the left and right sides of the fuel tank 161, respectively, preventing damage to the fuel tank 161 from external impacts and improving the safety of the fuel tank 161.

[0113] In summary, the motorcycle provided in this application can resist impacts from the sides of the motorcycle by means of the bottom brackets 1122 set on both sides of the fuel tank 161, effectively ensuring the safety of the fuel tank 161 during use; at the same time, the lower tank body 1613 of the fuel tank 161 can be completely accommodated in the receiving cavity, thereby further ensuring the volume of the fuel tank 161 without increasing the height of the foot pedal 121, which is conducive to improving the range of the motorcycle.

[0114] Please see the appendix Figure 20 As one implementation, the fuel system 16 also includes a fuel filler port 162 and a fuel guide pipe 163. The fuel guide pipe 163 connects the fuel filler port 162 to the fuel tank 161. The fuel guide pipe 163 is made of an elastic or flexible material; preferably, the fuel guide pipe 163 can be a rubber hose. By arranging the fuel filler port 162 and the fuel tank 161 separately, the position of the fuel filler port 162 can be arranged as needed. At the same time, by leading the fuel filler port 162 out of the fuel tank 161, the volume occupied by the fuel filler port 162 can be avoided, which is beneficial to further improving the motorcycle's range.

[0115] Of course, the oil guide tube 163 can also be made of metal. When the oil guide tube 163 is made of metal, it is pre-processed into a shape that is easy to install.

[0116] like Figure 20 As shown, the oil guide pipe 163 is attached to the upper housing 1612 of the oil tank 161, and a connecting portion for connecting the oil guide pipe 163 is provided on the upper housing 1612. For example, the connecting portion can be a metal connecting pipe, which is inserted into a flanged hole formed in the front part of the upper surface of the upper housing 1612 and welded to the hole. Alternatively, the metal connecting pipe can also be integrally formed with the upper housing 1612 by pressing or the like.

[0117] The oil guide pipe 163 is also provided with a fifth fixing part 1631 for fixing the oil guide pipe 163, so as to achieve positioning of the oil guide pipe 163 and avoid damage to the oil guide pipe 163 due to friction during vehicle use. Optionally, the oil guide pipe 163 can be fixed to the front of the rear frame 112, and the fuel tank 161 can be positioned through five fixing points, which helps to further improve the installation strength of the fuel tank 161.

[0118] Furthermore, such as Figure 21As shown, the body panel 12 includes a front cover 126; the front cover 126 covers at least a portion of the front frame 111 and the rear frame, and the front cover 126 is disposed opposite to the seat bucket 121. The fuel filler port 162 can be disposed on the side of the front cover 125 facing the seat bucket 121. Viewed along the height direction of the motorcycle, the fuel filler port 162 is located between the left rear frame 112 and the right rear frame 112. By placing the fuel filler port 162 inside the front cover 126, the space between the seat bucket 121 and the front cover 126 can be fully utilized, providing more operating space for refueling and making it easier for the rider to refuel.

[0119] Specifically, looking along the height of the motorcycle, such as Figure 19 As shown, the fuel filler neck 162 basically overlaps with the center lines of the left and right base brackets 1122. That is to say, in the width direction of the motorcycle, the fuel filler neck 162 is located in the middle of the motorcycle body; this arrangement can effectively reduce the damage to the fuel system 16 caused by side impacts during motorcycle use.

[0120] Viewed along the width of the motorcycle, as Figure 21 As shown, in the height direction of the motorcycle, the fuel filler neck 162 is positioned higher than the footrest 121 and lower than the upper surface of the seat 121. Preferably, with the upper surface of the footrest 121 as a reference, the height of the fuel filler neck 162 is no higher than half the height of the seat 121. That is to say, for the rider, the fuel filler neck 162 is located near the lower leg. This arrangement facilitates refueling and avoids increased maintenance costs due to excessively long fuel line 163.

[0121] Looking along the width of the motorcycle, the fuel line 163 extends forward and upward from the upper surface of the fuel tank 161, passes through a bend, and then extends upward and backward. The bend angle of the bend is greater than 90 degrees, which causes the opening of the fuel filler 162 to tilt towards the seat 121, thus facilitating the insertion of the fuel nozzle.

[0122] In summary, the motorcycle provided in this application, by arranging the fuel filler port 162 and the fuel tank 161 separately, allows for the arrangement of the fuel filler port 162 as needed. At the same time, it reduces the volume of the fuel tank 161 occupied by auxiliary components such as the fuel pump, which is beneficial to further improving the motorcycle's range.

[0123] Please see Figure 22In some embodiments, the vehicle body cover 12 further includes a battery box structure 125. The battery box 125 includes a battery box body 1251, which is a cylindrical structure with one end open. A battery receiving cavity 1251a is formed inside the cylindrical structure. The motorcycle battery is installed in the battery receiving cavity 1251a. A fuse box receiving cavity 1251b, a relay receiving cavity 1251c, and an OBD diagnostic interface receiving cavity 1251d are also formed inside the cylindrical structure. The fuse box receiving cavity 1251b, the relay receiving cavity 1251c, and the OBD diagnostic interface receiving cavity 1251d are arranged around the battery receiving cavity 1251a. By concentrating multiple different electrical components in the battery box structure 125, it is convenient to install, maintain, and service electrical components, while also making the wiring smoother and neater.

[0124] Furthermore, the battery receiving cavity 1251a is configured to communicate with the fuse box receiving cavity 1251b, the relay receiving cavity 1251c, and the OBD diagnostic interface receiving cavity 1251d, respectively. This allows the battery, after being installed in the battery receiving cavity 1251a, to act as a side wall of the cavity, supporting and positioning the electrical appliances. This arrangement eliminates the need for partitions between the chambers, further reducing the size of the battery box, and also facilitates the installation and securing of electrical appliances.

[0125] During installation, the fuse box cavity 1251b, relay cavity 1251c, and OBD diagnostic interface cavity 1251d can be configured according to actual space requirements. For example, since the relay and OBD diagnostic interface are relatively short, the relay cavity 1251c and OBD diagnostic interface cavity 1251d can be positioned opposite the battery cavity 1251a, i.e., respectively located on the sides where the two short sides of the battery are located. The fuse box, being relatively wide, can be positioned on the side where the long side of the battery is located.

[0126] To facilitate installation and connection, the depths of the fuse box cavity 1251b, the relay cavity 1251c, and the OBD diagnostic interface cavity 1251d are set according to the size of the electrical components, with the aim of ensuring that the surfaces of all electrical components are on the same horizontal plane after installation.

[0127] The Motorcycle 100 also features electrical equipment such as relays, fuse boxes, and OBD diagnostic interfaces. Optionally, such as... Figure 23As shown, to facilitate the installation of electrical equipment, the battery box body 1251 is also provided with a first clearance opening 1251e, a second clearance opening 1251h, and a third clearance opening 1251f. The first clearance opening 1251e is formed on at least one side wall of the fuse box receiving cavity 1251b, and the fuse box is connected to the wiring harness through the first clearance opening 1251e; thus, after the fuse box is installed, the wiring harness of the fuse box can be connected without opening the battery box structure 125.

[0128] The second clearance opening 1251h is formed on at least one side wall of the relay receiving cavity 1251c, and the relay wiring harness is connected through the second clearance opening 1251h; thus, after the relay is installed, the wiring harness of the relay can be connected without opening the battery box structure 125. The relay is provided with self-tapping screws, which are used to fix the relay to the battery box body 201.

[0129] Furthermore, a third clearance opening 1251f is formed on at least one side wall of the OBD diagnostic interface receiving cavity 1251d, and the OBD diagnostic interface is connected to the wiring harness through the third clearance opening 1251f. A positioning groove 1251g is provided at the bottom of the OBD diagnostic interface receiving cavity 1251d, and the positioning groove 1251g is configured to match the bottom shape of the OBD diagnostic interface.

[0130] Optionally, the bottom of the OBD diagnostic interface receiving cavity 1251d may also be provided with an OBD diagnostic interface fixing part for fixing the OBD diagnostic interface; wherein, the OBD diagnostic interface fixing part may be, for example, a fixing hole provided in the positioning groove 1251g.

[0131] Optionally, such as Figure 24 As shown, the battery box structure 125 also includes a cover 1252, which is configured to snap onto the battery box body 1251 to close the battery receiving cavity 1251a, the fuse box receiving cavity 1251b, the relay receiving cavity 1251c, and the OBD diagnostic interface receiving cavity 1251d. The outer peripheral edge of the cover 1252 is provided with a flange 1252a extending from the outer peripheral edge of the cover 1252 toward the battery box body 1251. The outer periphery of the opening of the cylindrical structure of the battery box body 1251 is formed with a locking groove 1251i, and the flange 1252a of the cover 1252 can be housed in the locking groove 1251i.

[0132] In summary, the motorcycle provided in this application, by providing a battery housing cavity 1251a, a fuse box housing cavity 1251b, a relay housing cavity 1251c, and an OBD diagnostic interface housing cavity 1251d within the battery box body 1251, wherein the fuse box housing cavity 1251b, the relay housing cavity 1251c, and the OBD diagnostic interface housing cavity 1251d are arranged around the battery housing cavity 1251a, multiple different electrical components are concentrated in the same battery box structure 125, which is beneficial for the installation, maintenance, and upkeep of electrical components, and at the same time makes the wiring smoother and neater.
