Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a motorcycle. Background Technology

[0002] Existing motorcycles contain numerous electrical components, such as rectifiers, voltage regulators, ignition controllers, and turn signals. These components, due to their different functions, are installed in different locations. For example, the ignition controller converts low-voltage electrical energy into high-voltage electrical energy to generate sufficient voltage to ignite the spark plugs, thus achieving engine ignition; therefore, the ignition controller is often located near the engine. The turn signal controller controls the flashing of the turn signals and is usually installed near the motorcycle's turn signals. During later maintenance and repair of these electrical components, it is necessary to maintain each component individually, making maintenance quite cumbersome. Utility Model Content

[0040] like Figures 2 to 3 As shown, the frame 11 is configured as a tubular structure with basic left-right symmetry. The frame 11 includes a main frame 111, a lower bracket 112, and a subframe 113. The lower bracket 112 is located below the main frame 111 and is fixedly connected to the main frame 111. A main receiving space 114 is formed between the lower bracket 112 and the main frame 111, and the engine 14 is located within this main receiving space 114. The subframe 113 is located at the rear end of the main frame 111 and the lower bracket 112, and is fixedly connected to both the main frame 111 and the lower bracket 112. A secondary receiving space 115 is formed between the main frame 111, the lower bracket 112, and the subframe 113, and the air filter assembly 15 is located within this secondary receiving space 115.

[0041] Specifically, such as Figures 1 to 2 As shown, the main frame 111 includes a head tube 1111, an upper main tube 1112, a lower main tube 1113, and a reinforcing cross tube 1114. The head tube 1111 is inclined at the front and cooperates with the steering system 20, allowing the upper end of the steering system 20 to rotate backward and forward to connect to the head tube 1111. The upper main tube 1112 is inclined along the length of the motorcycle 100, with its front end fixedly connected to the upper side of the rear end of the head tube 1111, and its rear end extending downward and backward towards the motorcycle 100. The lower main tube 1113 is positioned approximately along the height of the motorcycle 100, with its upper end fixedly connected to the lower side of the rear end of the head tube 1111. The reinforcing cross tube 1114 is horizontally fixed on the upper side between the upper main tube 1112 and the lower main tube 1113.

[0042] like Figure 2 As shown, the lower support frame 112 includes a lower support main tube 1121 and a lower support cross tube 1122. Two lower support main tubes 1121 are provided, symmetrically arranged on the left and right sides of the frame 11. The lower support main tubes 1121 are roughly U-shaped. The two ends of the left lower support main tube 1121 are fixedly connected to the left rear end of the upper main tube 1112 and the left lower end of the lower main tube 1113, respectively. The two ends of the right lower support main tube 1121 are fixedly connected to the right rear end of the upper main tube 1112 and the right lower end of the lower main tube 1113, respectively. Two lower support cross tubes 1122 are provided, basically horizontally fixed between the rear sides of the left and right lower support main tubes 1121, and located at the upper and lower parts of the rear side of the lower support main tubes 1121, respectively.

[0043] like Figure 2 As shown, the subframe 113 includes a main connector 1131, secondary cross braces 1132, secondary diagonal braces 1133, and a subframe tailplate 1134. The main connector 1131 is approximately triangular, with its front end fixedly connected to the rear end face of the upper main connector 1112. Two secondary cross braces 1132 are provided, arranged substantially horizontally and symmetrically on the left and right sides of the frame 11. The front ends of the two secondary cross braces 1132 are fixedly connected to the rear ends of the upper main connector 1112. Two secondary diagonal braces 1133 are provided, arranged with a slight incline at the front and a slight incline at the rear, and symmetrically on the left and right sides of the frame 11. The front ends of the two secondary diagonal bracing tubes 1133 are respectively connected to the rear ends of the two lower support main tubes 1121; the rear ends of the two secondary diagonal bracing tubes 1133 are respectively connected to the lower ends of the rear sides of the two secondary horizontal bracing tubes 1132. The sub-frame tail plate 1134 is fixedly connected between the rear ends of the two secondary horizontal bracing tubes 1132.

[0044] like Figure 2 and Figure 3 As shown, the engine 14 is housed within the main housing space 114. The upper end of the engine 14 is connected to the reinforcing horizontal tube 1114, the front end of the engine 14 is connected to the lower main tube 1113, and the lower end and rear end of the engine 14 are connected to two lower supporting horizontal tubes 1122, respectively. This ensures stable fixation between the engine 14 and the frame 11. The air filter assembly 15 is located at the rear of the secondary housing space 115, and its rear side is installed between two secondary diagonal support tubes 1133.

[0045] like Figure 3As shown, the body panel 12 includes a rear mudguard assembly 31 and a power protection assembly 32. The rear mudguard assembly 31 is mounted on the subframe 113 and is located behind the air filter assembly 15. The rear mudguard assembly 31 is used to prevent mud and water splashed by the wheels onto the rider's back and luggage when riding in rainy or muddy conditions. The power protection assembly 32 is located on the front and lower sides of the engine 14 to protect the engine 14 from mud splashed by the wheels or stones scraping against the engine 14.

[0046] like Figure 3 As shown, the rear fender assembly 31 includes a front plate 41 and a rear plate 42. The rear plate 42 is detachably connected to the rear side of the front plate 41, and the front side of the front plate 41 is connected to the subframe 113. Therefore, during the assembly of the rear fender assembly 31, the rear plate 42 can be first connected to the front plate 41 off the production line. Then, the rear fender assembly 31 is directly connected to the subframe 113 via the front plate 41 on the production line. This assembly method significantly speeds up the assembly process compared to the existing method of connecting the front plate 41, rear plate 42, and subframe 113 together on the production line.

[0047] like Figure 4 and Figure 5 As shown, the front plate 41 includes a rear mudguard body 411, an air filter abutment part 412, and a tailplate connecting part 413. The rear mudguard body 411 serves as the main body of the mudguard and is positioned above the rear wheel 132. The air filter abutment part 412 is integrally connected to the front end of the rear mudguard body 411 and abuts against the air filter assembly 15. The tailplate connecting part 413 is located at the rear end of the rear mudguard body 411 and is bolted to the tailplate 42. Furthermore, the front plate 41 also includes a front connecting part 416 and a rear connecting part 419. The front connecting part 416 is symmetrically arranged on the left and right sides of the subframe 113 and is bolted to the sub-bracing tube 1133 of the subframe 113. The rear connecting part 419 is located on the tailplate connecting part 413 and is bolted to the subframe tailplate 1134 of the subframe 113.

[0048] like Figure 4 and Figure 5As shown, the front connecting portion 416 includes a first side connecting portion 417 and a second side connecting portion 418. The first side connecting portion 417 and the second side connecting portion 418 are integrally connected to the left and right sides of the rear fender body portion 411, respectively. The first side connecting portion 417 has a first insert groove with an upward opening for the sub-bracing tube 1133 on the left side of the subframe 113 to be inserted. The second side connecting portion 418 has a second insert groove with an upward opening for the sub-bracing tube 1133 on the right side of the subframe 113 to be inserted. The sub-bracing tubes on the left and right sides of the subframe 113 are inserted into the first insert groove and the second insert groove from top to bottom, and the first insert groove and the second insert groove are respectively in contact with the lower side of the sub-bracing tube 1133 on the left and right sides of the subframe 113. The first side connecting portion 417 and the second side connecting portion 418 have two bolt holes in the horizontal direction for connecting the frame 11. A stable connection between the front panel 41 and the subframe 113 is achieved by driving bolts into the bolt holes of the first side connection portion 417 and the second side connection portion 418.

[0049] Furthermore, such as Figure 5 As shown, an exhaust connecting plate 1135 is fixedly connected to the rear side of the secondary diagonal brace tube 1133 on the right side of the subframe 113. The exhaust connecting plate 1135 is roughly trapezoidal in shape, wider at the top and narrower at the bottom. A plate-shaped clearance hole 4182 is provided on the second side connection part 418 for the exhaust connecting plate 1135 to pass through. The exhaust connecting plate 1135 not only bolts the exhaust assembly 16 but also reinforces the second side connection part 418.

[0050] like Figure 5 and Figure 6 As shown, the rear connecting portion 419 includes at least three rear connecting bosses 4191. In one embodiment, three rear connecting bosses 4191 are arranged in an isosceles triangle on the tail plate connecting portion 413, and the isosceles triangle formed by the three rear connecting bosses 4191 is symmetrical about the center line of the front plate 41 in the left-right direction. Each rear connecting boss 4191 has bolt holes for bolting the frame 11. The subframe tail plate 1134 of the subframe 113 is located above the rear connecting bosses 4191, so that the rear connecting portion 419 can be bolted to the subframe tail plate 1134 of the subframe 113.

[0051] like Figure 5 and Figure 6 As shown, the tailgate connection part 413 includes a tailgate support member 4131 and a side tailgate connector 4134. The tailgate support member 4131 is integrally connected to the rear end of the rear mudguard body part 411. The side tailgate connectors 4134 are integrally connected to the left and right sides of the rear mudguard body part 411 respectively. The lower side of the tailgate 42 is bolted to the tailgate support member 4131, and the front end of the tailgate 42 is bolted to the side tailgate connector 4134.

[0052] like Figure 5 and Figure 6 As shown, the side tail connectors 4134 on both sides each include an outer connector 4135, a tail plate abutment wall 4137, and an inner connector 4136. The outer connector 4135 is fixedly connected to the upper outer side of the rear mudguard body 411, and the tail plate abutment wall 4137 is fixedly connected to the rear end of the rear mudguard body 411. The outer side of the tail plate abutment wall 4137 is located behind the outer connector 4135, and the outer connector 4135 is fixedly connected to the outer side of the tail plate abutment wall 4137. The inner connector 4136 is fixedly connected to the upper inner side of the rear mudguard body 411, and the inner connector 4136 is located behind the inner side of the tail plate abutment wall 4137, and the inner connector 4136 is fixedly connected to the inner side of the tail plate abutment wall 4137. The outer connecting seat 4135 has bolt holes in the vertical direction, and the inner connecting seat 4136 has bolt holes in the vertical direction. The tail plate 42 is bolted to the outer connecting seat 4135 and the inner connecting seat 4136. The outer connecting seat 4135 is bolted to the lower outer end face of the tail plate 42, and the inner connecting seat 4136 is bolted to the upper inner end face of the tail plate 42. Furthermore, the upper end face of the tail plate abutment wall 4137 extends towards the tail plate 42, and the tail plate abutment wall 4137 abuts against the upper end face of the tail plate 42 to further improve the stability of the connection between the side tail connector 4134 and the front end of the tail plate 42, and to limit the tail plate 42 from flipping backward.

[0053] like Figure 6 As shown, the tailplate support 4131 is inclined at the front and lower at the rear, and the rear connecting part 419 is located at the front end of the tailplate support 4131. A cable routing groove 4132 with a front-to-back orientation is provided behind the rear connecting part 419 of the tailplate support 4131, and a cable clamping ring 4133 is provided in the cable routing groove 4132 of the tailplate support 4131.

[0054] Furthermore, the motorcycle 100 also includes a storage battery 22 (see...) Figure 13 The frame 11 supports the rear of the motorcycle 100 and is used to supply power to the motorcycle 100. Figure 4 and Figure 7 As shown, the front panel 41 also includes a battery mounting section 414 and a tool mounting section 415. The battery mounting section 414 is located in the middle of the rear fender body 411 and is used to house the battery 22; the tool mounting section 415 is located on the rear fender body 411 and in front of the battery mounting section 414 and is used to house tools; the battery mounting section 414 is located between the first side connecting section 417, the second side connecting section 418 and the rear connecting section 419, thereby providing stable support for the front panel 41 after the battery 22 is placed from the left, right and rear sides.

[0055] like Figure 7As shown, the battery mounting section 414 includes a mounting base plate 4141 and a mounting enclosure 4142. The mounting enclosure 4142 is fixedly connected to the upper surface of the mounting base plate 4141, and the mounting base plate 4141 and the mounting enclosure 4142 form a battery mounting groove 4144 for placing the battery 22. Several reinforcing ribs 4145 are arranged at intervals on the outer wall of the mounting enclosure 4142. A battery buffer pad 4143 is bonded and fixed to the upper surface of the mounting base plate 4141. The battery buffer pad 4143 is made of rubber and can provide a buffering effect for the battery.

[0056] like Figure 7 As shown, the tool placement section 415 includes a tool placement base plate 4151 and tool placement hooks 4152. The tool placement hooks 4152 are arranged in pairs, vertically positioned on the front and rear sides of the tool placement base plate 4151. The hook body of each tool placement hook 4152 is located at its upper end and faces away from the tool placement base plate 4151. A tool placement space 4153 is formed between the tool placement base plate 4151 and the hook bodies of the tool placement hooks 4152. Furthermore, there are at least two pairs of tool placement hooks 4152. In the embodiment of this application, two pairs of tool placement hooks 4152 are provided, positioned on the left and right sides of the tool placement base plate 4151. The tool placement space 4153 can hold tools such as wrenches and screwdrivers. After the tools are placed in the tool placement space 4153, the elastic cord is looped around the hooks of the paired tool placement hooks 4152. The hooks of the tool placement hooks 4152 prevent the elastic cord from slipping out, thus achieving stable fixation of the tools. The tool placement part 415 also includes a front tool baffle 4154, which is located on the front side of the tool placement base plate 4151 and between the two front tool placement hooks 4152. The front tool baffle 4154 is used to abut the tools and prevent them from slipping out from the front side of the tool placement part 415.

[0057] Furthermore, such as Figure 7 As shown, the tool mounting part 415 has a hook demolding hole 4155 below the tool mounting hook 4152 to facilitate the demolding of the tool mounting hook 4152. To prevent mud and water from entering the tool mounting part 415 through the hook demolding hole 4155, the tool mounting part 415 also includes a flip-up sealing plate 4156. The flip-up sealing plate 4156 is disposed on one side wall of the hook demolding hole 4155 opposite to the tool mounting hook 4152. The flip-up sealing plate 4156 can be flipped and connected to the side wall of the hook demolding hole 4155. By flipping, the flip-up sealing plate 4156 can engage with the bottom of the tool mounting hook 4152, thereby sealing the hook demolding hole 4155.

[0058] Furthermore, such as Figure 5 and Figure 8As shown, the tailgate 42 is attached to the tailgate connecting part 413, and the tailgate 42 and the wiring groove 4132 of the tailgate support 4131 form a wiring harness channel. The tailgate 42 is provided with a left turn signal 421, a right turn signal 422 and a rear reflector 424. The wiring harnesses of the left turn signal 421 and the right turn signal 422 are connected to the battery 22 through the wire clamping ring 4133 in the wiring groove 4132. The tail plate 42 has a tail plate reinforcing plate 425 protruding from its front end. The tail plate reinforcing plate 425 has a boss positioning hole that matches the rear connecting boss 4191. The tail plate reinforcing plate 425 overlaps the rear connecting part 419. When the rear connecting part 419 is bolted to the subframe tail plate 1134 of the subframe 113, the tail plate reinforcing plate 425 is bolted between the rear connecting part 419 and the subframe tail plate 1134, further improving the stability of the connection between the tail plate 42 and the tail plate connecting part 413.

[0059] like Figure 9 and Figure 10 As shown, the power protection assembly 32 includes a front power guard plate 43 and a bottom power guard plate 44. The front power guard plate 43 is located in front of the engine 14 and connects between the lower main pipe 1113 and the reinforcing cross pipe 1114. The bottom power guard plate 44 is located below the engine 14 and connects between the lower main pipe 1113 and the lower support pipe 1121. During the operation of the motorcycle 100, flying stones, mud, and other objects mainly fly from the front and below. The front power guard plate 43, located in front of the engine 14, can block flying stones and other hard objects from the front. The bottom power guard plate 44, located below the engine 14, blocks mud, sand, and flying stones splashed from the bottom of the motorcycle 100 towards the engine 14, thus achieving comprehensive protection for the engine 14.

[0060] like Figure 10 and Figure 11 As shown, the front power shield 43 includes a central section 431, side panels 432, and shield struts 433. The central section 431 is located between the lower main tube 1113 and the reinforcing cross tube 1114, and is bolted to the reinforcing cross tube 1114 to secure the front power shield 43 to the frame 11. There are two side panels 432, symmetrically arranged on both sides of the central section 431. The side panels 432 extend outwards, shielding the front of the engine 14 while directing airflow towards the engine 14 for cooling. The two ends of the shield struts 433 are connected to the outer rear of the side panels 432, providing horizontal support for the side panels 432.

[0061] like Figure 11As shown, the side baffle 432 includes an outer air guide frame 4321, an inner air guide plate 4322, and a reinforcing cross plate 4323. The outer air guide frame 4321 is generally a right-angled trapezoid with its longitudinal length gradually increasing from the inside to the outside. The inner sidewall of the outer air guide frame 4321 is integrally connected to the central connecting part 431. The outer sidewall of the outer air guide frame 4321 is longer than the inner sidewall, and the outer sidewall of the outer air guide frame 4321 has two outer frame bolt holes, through which the outer air guide frame 4321 is bolted to the external body panel 12. The upper sidewall of the outer air guide frame 4321 is horizontally connected to the upper ends of the inner and outer sidewalls, and the lower sidewall of the outer air guide frame 4321 is inclinedly connected to the lower ends of the inner and outer sidewalls. The inner air guide plates 4322 are evenly spaced along the horizontal width direction within the outer air guide frame 4321. The intervals between the inner air guide plates 4322 form air guide grid holes 4324. The inner air guide plates 4322 are inclined inward from front to back, causing the air entering through the air guide grid holes 4324 to be blown inward towards the engine 14. The reinforcing horizontal plates 4323 are evenly spaced along the vertical direction within the outer air guide frame 4321, connecting to the inner air guide plates 4322 and reinforcing the inner air guide plates 4322.

[0062] Furthermore, such as Figure 11 As shown, the air guide inner plate 4322 includes an upper inclined inner plate 4322a and a lower straight inner plate 4322b. The upper inclined inner plate 4322a is integrally connected to the upper side of the lower straight inner plate 4322b. The connection between the upper inclined inner plate 4322a and the lower straight inner plate 4322b forms a bend, which improves the strength of the air guide inner plate 4322 and the effect of guiding air to the engine 14.

[0063] like Figure 10 As shown, the two ends of the baffle strut 433 are horizontally fixed to the middle of the rear side of the outer wall of the air guide frame 4321 of the side baffles 432 by bolts, providing horizontal support for the side baffles 432. The baffle strut 433 includes a horizontal strut part 4331 and a side-diagonal strut part 4332. The horizontal strut part 4331 is located in the middle, and there are two side-diagonal struts 4332. The two side-diagonal struts 4332 are respectively located on both sides of the horizontal strut part 4331. One end of the side-diagonal struts 4332 is fixedly connected to the horizontal strut part 4331, and the other end is fixed to the outer wall of the air guide frame 4321. Therefore, in addition to providing horizontal support for the side baffles 432, the baffle strut 433 can also provide forward support force.

[0064] like Figure 10 and Figure 12As shown, the underbody protection plate 44 includes a lower protection plate portion 441 and a front protection plate portion 442. The lower protection plate portion 441 is located below the engine 14, and the two sides of the lower protection plate portion 441 are bolted to the lower support main tube 1121. The front protection plate portion 442 is integrally connected to the front end of the lower protection plate portion 441, and the middle part of the front protection plate portion 442 is bolted to the front end of the lower support main tube 1113. The bolts in the middle of the front protection plate portion 442 and the bolts on both sides of the lower protection plate portion 441 form a triangular bolt fixing between the underbody protection plate 44 and the frame 11, improving the stability of the underbody protection plate 44. Furthermore, the underbody protection plate 44 also includes two protection plate connecting portions 443, which are respectively obliquely fixed to the sides of the lower protection plate portion 441 and the front protection plate portion 442, reinforcing the underbody protection plate 44. Meanwhile, a side air vent 444 is formed between the guard plate connecting part 443, the lower guard plate part 441 and the front guard plate part 442.

[0065] like Figure 12 As shown, the front skid plate 442 is provided with an air intake grille 445, and the air outlet of the air intake grille 445 is inclined downwards towards the engine 14. This achieves heat dissipation from the bottom of the engine 14 while also preventing mud and water from splashing excessively onto the engine 14 through the air intake grille 445. Thus, the power protection assembly 32 protects the engine 14 while ensuring its heat dissipation.

[0066] like Figure 13 and 14 As shown, the motorcycle 100 also includes an electrical system 21, which is mounted on the frame 11 and provides electrical control for the motorcycle 100. The electrical system 21 includes an instrument cluster 17, located at the front of the motorcycle 100, for providing the driver with relevant vehicle information. The electrical system 21 also includes an electrical box unit 51, a first wiring harness group 55, and a second wiring harness group 56. The electrical box unit 51 is mounted on the subframe 113 and is located outside the air filter assembly 15. The electrical box unit 51 concentrates most of the wiring harnesses and electrical components of the motorcycle 100, increasing space for other parts of the vehicle and facilitating future maintenance of electrical components.

[0067] like Figure 13 and Figure 14As shown, the electrical box unit 51 includes an electrical box body 52, internal electrical components 53, and an internal adapter 54. The electrical box body 52 is mounted on one side of the vehicle frame 11 and is located on the outer wall of the air filter assembly 15 between the engine 14 and the battery 22. The first wiring harness group 55 is located above the electrical box body 52, and the path of the first wiring harness group 55 is from the battery 22 towards the instrument assembly 17. The second wiring harness group 56 is located below the electrical box body 52, and the path of the second wiring harness group 56 is from the electrical box body 52 towards the engine 14. The internal adapter 54 is installed inside the electrical box body 52 and is connected between the first wiring harness group 55 and the second wiring harness group 56. The internal electrical components 53 are installed inside the electrical box body 52 and are directly electrically connected to the first wiring harness group 55 or indirectly electrically connected to the first wiring harness group 55 via the internal adapter 54.

[0068] Most of the wiring harness of the motorcycle 100 follows the path of the first wiring harness group 55 and the second wiring harness group 56. The electrical box 52 is located between the first wiring harness group 55 and the second wiring harness group 56. The adapter on the electrical box 52 can electrically connect the first wiring harness group 55 and the second wiring harness group 56 together, so that the electrical components 53 inside the electrical box 52 only need a very short length to be connected to the overall wiring harness of the motorcycle 100. Therefore, this solution not only realizes the functions of each electrical component, but also centralizes the wiring harness and electrical components of the motorcycle 100, increasing the space for other parts of the motorcycle 100 and providing convenience for later maintenance of electrical components.

[0069] Specifically, such as Figure 14 and Figure 15 As shown, the electrical box 52 is fixed to the left side of the frame 11. The electrical box 52 includes a front placement part 521, a rear placement part 522, and a mating reinforcement part 523. The front placement part 521 and the rear placement part 522 are used to install the electrical components 53 and the adapter connectors 54 inside the box. The front placement part 521 is located in front of the rear placement part 522 and is located in front of the air filter assembly 15; the rear placement part 522 is located on the outer wall of the air filter assembly 15. Therefore, the front placement part 521 is deeper than the rear placement part 522, so that the front placement part 521 can accommodate a larger electrical component 53 inside the box. The reinforcing part 523 is located on the rear side of the rear placement part 522. The front inner wall of the reinforcing part 523 abuts against the auxiliary diagonal support tube 1133, and the rear inner wall of the reinforcing part 523 abuts against the front side wall of the front panel 41. Therefore, the reinforcing part 523 not only fixes the electrical box 52 to the frame 11, but also reinforces the front panel 41. Furthermore, in order to improve the stability of the electrical box 52, a thickened connecting part 5221 is provided on the rear placement part 522. The thickened connecting part 5221 is fixed to the air filter assembly 15 by bolts, so that the inner wall of the rear placement part 522 fits against the air filter assembly 15.

[0070] like Figure 14 and Figure 15 As shown, the adapter 54 is vertically mounted on the rear placement part 522. The adapter 54 includes an upper connection end connecting the first wiring harness group 55 and a lower connection end connecting the second wiring harness group 56 and the electrical components 53 inside the box. A dust cover 541 is fitted onto the adapter 54. The dust cover 541 includes an upper opening fitted onto the upper connection end and a lower opening fitted onto the lower connection end. The size of the upper opening is smaller than the size of the lower opening. Therefore, the smaller upper opening of the dust cover 541 can prevent dust from falling into the upper connection end of the adapter 54 from both above and below, while the larger lower opening of the dust cover 541, facing downwards, can not only prevent dust from falling into the lower end of the adapter 54, but also does not close the adapter 54, facilitating the installation and removal of the connectors of the electrical components 53 inside the box.

[0071] like Figure 14 and Figure 15 As shown, the electrical components 53 inside the box include an ignition controller 531, a lamp flasher 532, a rectifier voltage regulator 533, and a starting relay 534. The ignition controller 531, the lamp flasher 532, and the rectifier voltage regulator 533 are mounted on the front placement part 521, and the starting relay 534 is mounted on the rear placement part 522. Specifically, the ignition controller 531 and the lamp flasher 532 are mounted on the upper side of the front placement part 521, and the rectifier voltage regulator 533 is mounted on the lower side of the front placement part 521. There is a heat dissipation gap between the rectifier voltage regulator 533, the ignition controller 531, and the lamp flasher 532. A wiring harness clearance hole 5211 is provided on the upper side of the front placement part 521, through which the ignition controller 531 and the lamp flasher 532 are directly electrically connected to the first wiring harness group 55. The rectifier voltage regulator 533 and the starting relay 534 are directly electrically connected to the lower connection terminal of the conversion connector 54 inside the box through the lower opening of the connector dust cover 541.

[0072] Furthermore, such as Figure 14 and Figure 15 As shown, electrical heat dissipation holes 5212 are provided on the front and rear side walls of the front placement part 521. The electrical heat dissipation holes 5212 are preferably louvered holes, which can cool down the ignition controller 531, the lamp flasher 532 and the rectifier voltage regulator 533, while also preventing dust from entering the electrical box 52 as much as possible.

[0073] like Figure 14 As shown, a plurality of first wire harness cable ties 57 connecting the first wire harness group 55 are arranged at intervals on the outer wall of the upper side wall of the electrical box 52; a plurality of second wire harness cable ties 58 connecting the second wire harness group 56 are arranged at intervals on the inner wall of the lower side wall of the electrical box 52; and a wire harness through hole for the second wire harness group 56 to pass through is provided on the side wall of the electrical box 52 facing the engine 14.

[0074] like Figure 14 As shown, the first wiring harness group 55 and the second wiring harness group 56 include at least one or more of the following: power harness, ignition harness, signal harness, instrument harness, starter harness, and ground harness. The power harness connects the battery and generator, providing power to the electrical equipment of the motorcycle 100. The ignition harness connects the igniter, high-voltage coil, and spark plugs, serving as the ignition system for the engine 14. The signal harness connects turn signals, brake lights, etc., providing signal indications for the vehicle. The instrument harness connects various instruments of the motorcycle 100, such as the speedometer, tachometer, and fuel gauge. The starter harness connects the starter motor and battery, used to start the engine 14. The ground harness connects to the metal body of the motorcycle 100, serving as a circuit return.

[0075] like Figure 16 and Figure 17 As shown, the front suspension assembly 18 includes an upper connecting plate 181, a lower connecting plate 182, front shock absorbers 183, and a shock absorber cover 184. The upper connecting plate 181 is located at the upper end of the head tube 1111, and the lower connecting plate 182 is located at the lower end of the head tube 1111. The upper end of the head tube 1111 is rotatably connected to the upper connecting plate 181, and the lower end of the head tube 1111 is rotatably connected to the lower connecting plate 182. Two front shock absorbers 183 are provided, and the two front shock absorbers 183 are located on both sides of the front wheel 131. The front wheel 131 is rotatably connected to the lower side of the front shock absorber 183 through the front wheel axle. The upper side of the front shock absorber 183 passes through the upper connecting plate 181 and the lower connecting plate 182 respectively, and is adjustablely connected to the upper connecting plate 181 and the lower connecting plate 182 respectively. Two shock absorber covers 184 are provided. The two shock absorber covers 184 are respectively fixed to the outer wall of the two front shock absorbers 183 at the lower wheel position, in order to prevent mud and water from entering the front shock absorbers 183 during the motorcycle 100's operation.

[0076] like Figure 17 As shown, the front shock absorber 183 includes a fork top tube 451, a sealing tube 452, and a shock-absorbing bottom tube 453. The top of the fork top tube 451 is inserted into the upper connecting plate 181 and the lower connecting plate 182; the bottom of the fork top tube 451 is inserted into the shock-absorbing bottom tube 453, and a shock-absorbing structure is provided between the fork top tube 451 and the shock-absorbing bottom tube 453. The shock-absorbing structure allows the fork top tube 451 to slide away from the shock-absorbing bottom tube 453 when not under stress; the shock-absorbing structure is a spring, a hydraulic rod, or a combination thereof. The sealing tube 452 connects the fork top tube 451 and the shock-absorbing bottom tube 453, preventing external mud and sand from entering the shock-absorbing bottom tube 453.

[0077] like Figure 17As shown, the shock-absorbing base cylinder 453 includes a base cylinder main body 4531, a wheel axle connecting part 4532, and a protective cover connecting part 4533. The base cylinder main body 4531 serves as the main body of the shock-absorbing base cylinder 453. The wheel axle connecting part 4532 connects the front wheel axle to the base cylinder main body 4531, and the protective cover connecting part 4533 connects the shock-absorbing protective cover 184 to the base cylinder main body 4531. Specifically, the wheel axle connecting part 4532 is integrally connected to the lower side of the front outer wall of the base cylinder main body 4531. The wheel axle connecting part 4532 has a wheel axle connecting hole, through which the front wheel axle passes to achieve a rotatable connection with the wheel axle connecting part 4532. The wheel axle connecting part 4532 is provided with a reinforcing rib that is generally triangular in shape, so that the wheel axle connecting part 4532 can be stably fixed to the base cylinder main body 4531.

[0078] like Figure 17 As shown, the protective cover connecting part 4533 includes several threaded connecting posts 4535 integrally connected to the bottom cylinder main body part 4531. Bolt grooves are provided on the threaded connecting posts 4535, and the shock-absorbing protective cover 184 is connected to the threaded connecting posts 4535 by bolts. Specifically, three threaded connecting posts 4535 are provided. The protective cover connecting part 4533 includes two positive connecting posts 4535a located on the outer side wall of the bottom cylinder main body part 4531 and one front connecting post 4535b located on the front side wall of the bottom cylinder main body part 4531. The two positive connecting posts 4535a are located on the upper and lower sides of the outer side wall of the bottom cylinder main body part 4531, respectively. The front connecting post 4535b is integrally connected to the reinforcing rib on the upper side of the wheel axle connecting part 4532. Thus, the three threaded connecting posts 4535 achieve omnidirectional fixation between the bottom cylinder main body part 4531 and the shock-absorbing protective cover 184 from the upper, lower, and front positions. Furthermore, because the front connecting post 4535b is reinforced by the wheel axle connection part 4532, a high connection strength can be maintained between the front connecting post 4535b and the bottom cylinder body part 4531.

[0079] Furthermore, such as Figure 16 and Figure 17 As shown, the motorcycle 100 also includes a front brake assembly 26, which is located entirely to the left of the front wheel 131 of the motorcycle 100. The left shock absorber base 453 also includes a front brake connection part 4534, which is disposed on the rear side wall of the base body 4531 and is used to connect the front brake assembly 26. The front brake connection part 4534 includes two brake connection lugs 4538, each of which has a brake connection hole. The front brake assembly 26 is fixedly connected to the rear side wall of the base body 4531 by bolts to the two brake connection holes.

[0080] Furthermore, such as Figure 17As shown, the shock absorber cover 184 is fixed to the shock absorber base cylinder 453 by three threaded connecting columns 4535 bolts. The shock absorber cover 184 includes a main cover body 461 and a front cover body 462, with the front cover body 462 integrally connected to the front side of the main cover body 461. A positive thickening column 463 protrudes from the inner wall of the main cover body 461 at positions corresponding to the two positive connecting columns 4535a; a front thickening column 464 protrudes from the inner wall of the front cover body 462 at positions corresponding to the front connecting column 4535b. When the shock absorber cover 184 is bolted to the shock absorber base cylinder 453, the positive thickening column 463 abuts against the positive connecting column 4535a, and the front connecting column 4535b abuts against the front thickening column 464, improving the stability of the connection between the shock absorber cover 184 and the shock absorber base cylinder 453.

[0081] Furthermore, such as Figure 17 As shown, a side reflector 465 is fixed on the outer wall of the main body 461. The side reflector 465 can reflect light from vehicles on the side or behind, making the motorcycle 100 easier for other drivers to see at night or in low-light environments.

[0082] like Figure 17 As shown, the front cover portion 462 is inclined from front to back in an inward-outward direction, so that mud or stones splashed on the front side are ejected outwards after contact with the front cover portion 462, preventing mud or stones from directly splashing onto the shock-absorbing base cylinder 453. A front clearance groove 466 is provided on the upper side of the front cover portion 462. The front clearance groove 466 allows the upper side of the front cover portion 462 to fit against the front sidewall of the shock-absorbing base cylinder 453, and the lower side of the front cover portion 462 to fit against the wheel axle connection portion 4532 of the shock-absorbing base cylinder 453; thus improving the installation strength of the front cover. A wheel axle clearance hole 467 is provided on the front cover portion 462 at the position of the front wheel axle. The wheel axle clearance hole 467 allows for easy operation, enabling the front wheel axle to be disassembled without removing the shock-absorbing cover 184.

[0083] Reference Figure 16 and Figure 18The motorcycle 100 also includes a rear brake assembly 23, which is located on the right side of the rear wheel 132. The rear brake assembly 23 includes a rear brake disc 61, a rear brake caliper 62, a rear brake hydraulic system 63, a rear brake pedal 64, and a return spring 65. The rear brake disc 61 is mounted on the rear wheel 132; the rear brake caliper 62 is mounted on the rear suspension assembly 19, and the caliper jaws of the rear brake caliper 62 are provided with brake shoes facing the rear brake disc 61; the rear brake pedal 64 is rotatably mounted on the right side of the frame 11. The rear brake hydraulic system 63 is linked to the rear brake pedal 64 and the rear brake caliper 62, so that when the rear brake pedal 64 is pressed by the rider, the rear brake hydraulic system 63, in conjunction with the brake shoes on the rear brake caliper 62, clamps the rear brake disc 61, thereby braking the rear wheel 132. The return spring 65 connects the rear brake pedal 64 and the frame 11. When the driver releases the rear brake pedal 64, the rear brake pedal 64 returns to its initial position under the elastic action of the return spring 65. The rear brake hydraulic system 63 then releases the brake shoes on the rear brake caliper 62, thus ending the braking of the rear wheel 132.

[0084] like Figure 19 and Figure 20 As shown, the rear brake pedal 64 is mounted on the right lower support tube 1121. The rear brake pedal 64 includes a pedal rocker arm 641, a rocker arm pin 642, and a pedal 643. The pedal rocker arm 641 serves as the main body of the rear brake pedal 64; the rocker arm pin 642 is fixedly connected to the inner rear wall of the pedal rocker arm 641. A rocker arm connector 1123 is fixed to the rear side of the right lower support tube 1121, and the rocker arm pin 642 is inserted into the rocker arm connector 1123, realizing a rotatable connection between the rear brake pedal 64 and the lower support tube 1121 with the rocker arm pin 642 as the axis. The pedal 643 is fixedly connected to the outer front wall of the pedal rocker arm 641. The pedal 643 is provided with serrated friction patterns.

[0085] like Figure 19 and Figure 20As shown, the foot pedal rocker arm 641 comprises, from back to front, a rear rocker arm 6411, a horizontal rocker arm 6412, a front rocker arm 6413, and a pedal rocker arm 6414. The rear rocker arm 6411 is inclined at the front and downwards, and the rear brake hydraulic system 63 is hinged to the rear end of the rear rocker arm 6411. The rocker arm pin 642 is located near the rear end of the rear rocker arm 6411 and is welded to the rear side wall of the rear rocker arm 6411. Therefore, when the foot pedal rocker arm 641 rotates along the rocker arm pin 642, the rear end of the rear rocker arm 6411 swings slightly into the rear brake hydraulic system 63, thereby controlling the braking of the rear wheel 132. The horizontal rocker arm 6412 is roughly horizontal, placing it at the highest point of the overall foot pedal rocker arm 641. The front rocker arm 6413 is vertically inclined downwards. Since the front rocker arm 6413 is located on the outside of the engine 14 in the horizontal direction, in order to avoid interference between the front rocker arm 6413 and the engine 14, the front rocker arm 6413 is inclined outwards in the horizontal direction, so that there is a clearance between the front rocker arm 6413 and the engine 14.

[0086] like Figure 19 As shown, the motorcycle 100 also includes pedal assemblies 24. Two pedal assemblies 24 are provided, each mounted on a lower support tube 1121 on either side of the frame 11 and fixedly connected to the lower support tube 1121. The pedal assemblies 24 on both sides support the driver's feet and facilitate gear shifting or braking. A roughly trapezoidal clearance space is formed between the front swingarm 6413, the horizontal swingarm 6412, and the rear swingarm 6411. The right-side pedal assembly 24 is located within this clearance space, allowing for clearance between the pedal swingarm 641 and the pedal assembly 24. The pedal swingarm 6414 is horizontally positioned, and the pedal 643 is fixedly connected to the front side of the pedal swingarm 6414.

[0087] like Figure 19 and Figure 20As shown, the rear brake pedal 64 also includes a front spring mount 644, which is fixed to the inner wall of the rocker arm 6412 and located slightly rear of the center of the rocker arm 6412, providing clearance between the front spring mount 644 and the engine 14. The lower support tube 1121 on the right side is fixed to the upper side behind the front spring mount 644, and a return spring 65 is connected between the front spring mount 644 and the rear spring mount 66. Since the rocker arm 6412 is located at the high point of the pedal rocker arm 641, the return spring 65 connecting the front spring mount 644 and the rear spring mount 66 is also located at the high point of the entire rocker arm, thus giving the return spring 65 a higher ground clearance and reducing the risk of decreased rebound performance due to external object impacts. Furthermore, the ground clearance of the lowest point of the return spring is at least 300mm, and preferably between 310mm and 360mm. In this embodiment, the ground clearance of the lowest point of the return spring is 340mm, ensuring the ground clearance of the return spring while also preventing the rear brake pedal 64 from interfering with the engine 14 and the frame 11. Specifically, the front spring mount 644 is plate-shaped, and the front end of the front spring mount has a spring mounting groove 645 for the front end of the return spring 65 to be engaged. The rear spring mount 66 is pin-shaped, and an annular mounting groove is provided on the rear spring mount 66, into which the rear end of the return spring 65 is engaged.

[0088] In one implementation scheme, such as Figure 19 and Figure 20 As shown, a pedal limiting member 67 is provided above the rear rocker arm 6411 on the lower support main tube 1121. The pedal limiting member 67 abuts against the upper side wall of the rear rocker arm 6411, restricting the upward swing of the foot pedal rocker arm 641. Specifically, the pedal limiting member 67 includes a limiting mounting plate 671 fixedly connected to the lower support main tube 1121 and a pedal limiting bolt 672 bolted to the limiting mounting plate 671. The distance between the pedal limiting bolt 672 and the foot pedal rocker arm 641 can be adjusted by thread to achieve a more precise limiting effect. In addition, since the front end of the foot pedal rocker arm 641 is hinged to the rear brake hydraulic system 63, when the rear brake pedal 64 is pressed, the rear brake hydraulic system 63, in conjunction with the brake shoes on the rear brake caliper 62, clamps the rear brake disc 61 to brake the rear wheel 132. At the same time, the rear brake hydraulic system 63 will also provide a reaction force to the rear brake pedal 64, limiting the rotation of the rear brake pedal 64. Therefore, the range of rotation of the rear brake pedal 64 is limited to about 10 degrees, ensuring that the rear brake pedal 64 will not collide with the frame 11, engine 14 and pedal assembly 24.

[0089] like Figure 21As shown, the motorcycle 100 also includes a chain assembly 25 that drives the engine 14 and the rear wheel 132. The chain assembly 25 includes a drive sprocket 251, a drive chain 252, and a driven sprocket 253. The drive sprocket 251 is driven by the engine 14, enabling the engine 14 to drive the drive sprocket 251 to rotate. The driven sprocket 253 is driven by the rear wheel 132, enabling the driven sprocket 253 to drive the rear wheel 132 to rotate. The drive sprocket 251 and the driven sprocket 253 are driven by the drive chain 252, realizing the transmission of power from the engine 14 to the rear wheel 132. A protective block 1124 is installed on the lower support tube 1122 below the drive chain 252 on the frame 11. There is a gap between the protective block 1124 and the drive chain 252, so that the protective block 1124 will not affect the chain drive. The protective block 1124 is made of rubber, and the upper end surface of the protective block 1124 forms an elastic buffer part, thereby preventing damage caused by the collision between the drive chain 252 and the lower support tube 1122.

[0090] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
