[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific implementation modes of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation modes of the present application.

[0037] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0038] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0039] This application provides Figure 1 The motorcycle 100 shown includes a frame 11, a body covering 12, a suspension assembly 13, a traveling assembly 14 and a power system 15. The body covering 12 is at least partially disposed on the frame 11. The suspension assembly 13 is connected to the frame 11, and the traveling assembly 14 is connected to the frame 11 through the suspension assembly 13. The power system 15 is at least partially disposed on the frame 11, and the power system 15 is transmission-connected to the traveling assembly 14. The traveling assembly 14 includes a front wheel 141 disposed at the front end of the motorcycle 100 and a rear wheel 142 disposed at the rear end of the motorcycle 100. Specifically, the power system 15 is at least partially disposed in transmission connection with the rear wheel 142. It is also defined as follows: Figure 1 The front side, rear side, left side, right side, upper side and lower side shown are used as the front side, rear side, left side, right side, upper side and lower side of a motorcycle.

[0040] like Figure 2 As shown, as an implementation, the frame 11 is configured as a tubular frame that is substantially symmetrical left and right, and the frame 11 includes a main frame 111, a sub-frame 112, and an additional frame 113. The main frame 111 is disposed on the front side of the sub-frame 112 and is fixedly connected to the sub-frame 112. The additional frame 113 is at least partially disposed on the lower side of the main frame 111, and the additional frame 113 is configured to be detachably connected to the main frame 111.

[0041] Specifically, the main frame 111 includes a head tube 1111, an upper main tube 1112 and a stand tube 1113. The head tube 1111 is at least partially connected to the suspension assembly 13. The upper main tube 1112 is arranged between the head tube 1111 and the stand tube 1113. One end of the upper main tube 1112 is fixedly connected to the head tube 1111, and the other end of the upper main tube 1112 is fixedly connected to the stand tube 1113. The upper main tube 1112 is arranged to extend substantially from the head tube 1111 to the rear lower part of the motorcycle 100, and the stand tube 1113 is arranged to extend substantially along the height direction of the motorcycle 100. An upper cross tube 1114 is arranged between the upper main tube 1112 and the stand tube 1113, and the upper cross tube 1114 is arranged to extend along the width direction. Among them, the upper main tube 1112, the upper cross tube 1114 and the stand tube 1113 are fixedly connected, and the above three fixed connection methods include but are not limited to welding and integral molding.

[0042] like Figure 1 and Figure 2 As shown, more specifically, the main frame 111 includes a reference seat inner plate 1115 fixedly connected to the seat tube 1113, and the main frame 111 also includes a middle transverse tube 1116 at least partially arranged between a pair of left and right reference seat inner plates 1115, and the middle transverse tube 1116 is arranged to extend substantially along the width direction. The suspension assembly 13 also includes a rear fork 131, one end of the rear fork 131 is arranged to be rotatably connected to the middle transverse tube 1116, and the other end of the rear fork 131 is arranged to be rotatably connected to the rear wheel 142. The reference seat inner plate 1115 is arranged to strengthen the structural strength of the seat tube 1113, reduce the influence of the torque generated by the shaking of the rear wheel 142 on the main frame 111, and avoid the deformation of the seat tube 1113 caused by the torque applied by the rear fork 131.

[0043] like Figure 1 and Figure 3As shown, as an implementation, the subframe 112 includes an upper bracket 1121 and a lower bracket 1122 that are basically distributed along the height direction, defining a longitudinal plane 101 perpendicular to the width direction of the motorcycle 100, and the motorcycle 100 is basically bilaterally symmetrical with respect to the longitudinal plane 101. A first straight line 102 and a second straight line 103 are also defined. The projection of the upper main pipe 1112 on the longitudinal plane 101 along the width direction of the motorcycle 100 is set to extend basically along the first straight line 102, and the projection of the upper bracket 1121 on the longitudinal plane 101 along the width direction of the motorcycle 100 is set to extend basically along the second straight line 103. As an optional embodiment, the angle α between the first straight line 102 and the second straight line 103 can be set to be greater than or equal to 100° and less than or equal to 150°. Specifically, the angle α between the first straight line 102 and the second straight line 103 is set to be greater than or equal to 112° and less than or equal to 138°. More preferably, the angle α between the first straight line 102 and the second straight line 103 can be set to 125°. The body cover 12 also includes a seat cushion 121. The above arrangement allows a certain difference between the highest point of the motorcycle 100 and the lowest point of the seat cushion 121, so that the height of the seat cushion 121 can be lowered without lowering the height of the motorcycle 100. If the highest point of the motorcycle 100 remains unchanged, if the angle α is too large, the difference between the highest point of the motorcycle 100 and the lowest point of the seat cushion 121 is small, which is not conducive to the driver supporting the motorcycle 100 when parking. If the angle α is too small, although it is more conducive to the driver supporting the motorcycle 100, it reduces the riding comfort of the driver.

[0044] In summary, by setting the angle α between the upper main pipe 1112 and the upper bracket 1121, the driving needs of drivers of different heights for travel motorcycles are met while ensuring the comfort of the driver riding the motorcycle 100. Since about 60% of the driving scenarios of the motorcycle 100 proposed in this application are off-road, in this riding scenario, the driver needs to adjust the riding posture to ensure that the vehicle passes the driving scenario better, that is, the driver needs to switch back and forth between standing riding and sitting riding. The above setting is more conducive to the driver changing the riding posture during riding.

[0045] like Figure 3As shown, one end of the upper bracket 1121 is fixedly connected to the upper main pipe 1112 through the upper connection point 1121a, and the other end of the upper bracket 1121 is fixedly connected to the lower bracket 1122; one end of the lower bracket 1122 is fixedly connected to the upper bracket 1121, and the other end of the lower bracket 1122 is fixedly connected to the vertical pipe 1113 through the lower connection point 1122a. The projection of the axis of the head pipe 1111 along the width direction on the longitudinal plane 101 is defined as the first projection line 104. The projection of the upper connection point 1121a along the width direction on the longitudinal plane 101 is defined as the first projection point, and the projection of the lower connection point 1122a along the width direction on the longitudinal plane 101 is defined as the second projection point. As an optional embodiment, the upper connection point 1121a and the lower connection point 1122a can be set as through holes, and the upper bracket 1121 and the lower bracket 1122 can be respectively set to be fixedly connected with the upper main pipe 1112 and the vertical pipe 1113 by bolts. Specifically, when the upper connection point 1121a and the lower connection point 1122a are set to circular through holes, the first projection point and the second projection point are respectively defined as the projection of the axis of the through hole or the center of the circle along the width direction on the longitudinal plane 101; when the upper connection point 1121a and the lower connection point 1122a are set to other irregularly shaped connection methods, the first projection point and the second projection point are respectively defined as the projection of the center of gravity of the connection point or the intersection between the axis of the subframe 112 and the axis of the upper main pipe 1112 along the width direction on the longitudinal plane 101.

[0046] like Figure 3As shown, the spacing between the first projection point and the second projection point is defined as the first installation spacing L1 of the subframe 112, and the spacing between the second projection point and the first projection line 104 is defined as the second installation spacing L2 of the subframe 112. As an optional embodiment, the ratio between the first installation spacing L1 and the second installation spacing L2 is set to be greater than or equal to 0.16 and less than or equal to 0.24. Specifically, the ratio between the first installation spacing L1 and the second installation spacing L2 can also be set to be greater than or equal to 0.18 and less than or equal to 0.22. More preferably, the ratio between the first installation spacing L1 and the second installation spacing L2 is set to be equal to 0.2. If the ratio between the first installation spacing L1 and the second installation spacing L2 is too large, the connection between the lower bracket 1122 and the seat tube 1113 will be offset to the bottom of the motorcycle 100, causing the subframe 112 to affect the arrangement of the rear fork 131 and / or the rear wheel 142 in the already compact space of the motorcycle 100. In addition, since about 60% of the driving scenarios of the motorcycle 100 proposed in the present application are off-road, the vibration amplitude of the motorcycle 100 is greater than that of a road motorcycle, so the subframe 112 needs to bear greater pressure in the height direction to avoid damage to the subframe 112. If the ratio between the first installation interval L1 and the second installation interval L2 is too small, the connection between the upper bracket 1121 and the main frame 111 and the connection between the lower bracket 1122 and the main frame 111 will be smaller in the height direction, and the connection strength between the subframe 112 and the main frame 111 cannot be guaranteed.

[0047] The above arrangement can ensure the compactness of the structure of the motorcycle 100 while taking into account the connection strength between the sub-frame 112 and the main frame 111 , thereby improving the off-road performance and safety of the motorcycle 100 during driving.

[0048] like Figure 4As shown, further, a straddling portion 1121b tightened toward the longitudinal plane 101 is provided on one side of the upper bracket 1121 close to the main frame 111. The width between the two upper connection points 1121a of the upper bracket 1121 and the upper main pipe 1112 is defined as the first width L3. Specifically, the upper bracket 1121 and the upper main pipe 1112 are configured to be in surface contact, and the first width L3 in the present application is specifically defined as the distance between the two contact surfaces between the upper bracket 1121 and the upper main pipe 1112. The width of the straddling portion 1121b distributed in the width direction is defined as the second width L4, and specifically, the second width L4 is set to be the shortest distance of the upper bracket 1121 in the width direction. As an optional embodiment, the ratio between the second width L4 and the first width L3 can be set to be greater than or equal to 0.7 and less than or equal to 1. Specifically, the ratio between the second width L4 and the first width L3 can also be set to be greater than or equal to 0.75 and less than or equal to 0.95. Preferably, the ratio between the second width L4 and the first width L3 is limited to be equal to 0.85. It should be noted that if the ratio between the second width L4 and the first width L3 is too large, the width of the straddling portion 1121b will increase. In particular, on a motorcycle 100 with a large body height, the seat cushion 121 or the subframe 112 will interfere with the driver's legs in the width direction, which is not conducive to the driver's support of the motorcycle 100 when the vehicle is stationary; when the driver is standing and riding, the straddling portion 1121b with a narrower distribution in the width direction has less impact on the driver's legs, thereby improving the driver's comfort. In addition, since the width of the seat cushion 121 distributed in the width direction is basically the same as the width of the subframe 112 distributed in the width direction, it is ensured that the subframe 112 has sufficient support for the seat cushion 121. If the ratio between the second width L4 and the first width L3 is too small, the width of the straddling portion 1121b will be reduced, thereby reducing the contact surface between the seat cushion 121 and the driver, and thus failing to meet the driver's riding comfort.

[0049] It can be understood that the above settings can ensure the driver's riding comfort while meeting different driving scenarios of the driver.

[0050] like Figure 3As shown, the sub-frame 112 further includes a reinforcing rod 1123, which is arranged between the upper bracket 1121 and the lower bracket 1122, and the reinforcing rod 1123 is symmetrically distributed on the left and right sides of the sub-frame 112 with respect to the longitudinal plane 101. One end of the reinforcing rod 1123 is fixedly connected to the straddling portion 1121b of the upper bracket 1121, and the other end of the reinforcing rod 1123 is fixedly connected to the lower bracket 1122. Therefore, after the straddling portion 1121b of the upper bracket 1121 is tightened toward one side of the longitudinal plane 101, it still has a high structural strength. Specifically, the reinforcing rod 1123 is set as a hollow tubular frame, and the width of the reinforcing rod 1123 in the width direction is reduced by extrusion. Optionally, the reinforcing rod 1123 after extrusion is substantially rectangular or elliptical in cross section perpendicular to the height direction. It should be noted that, since the motorcycle 100 also includes a battery 105 that is at least partially arranged on the sub-frame 112, the aforementioned riding portion 1121b is tightened in the width direction. In order to avoid interference between the battery 105 and the sub-frame 112, the above-mentioned arrangement squeezes the reinforcing rod 1123 so that there is more arrangement space between the reinforcing rods 1123 on the left and right sides to arrange the battery 105 of the motorcycle 100, thereby improving the compactness of the motorcycle 100.

[0051] In order to improve the aesthetics of the motorcycle 100 and avoid the exposure of the tube body of the frame 11, the body cover 12 is at least partially arranged between the upper bracket 1121 and the lower bracket 1122. As can be seen from the above, the motorcycle 100 proposed in this application can enable the driver to support the vehicle when the vehicle is stationary, and in order to ensure the comfort of the driver when standing and riding, the body cover 12 between the upper bracket 1121 and the lower bracket 1122 is also at least partially arranged on the inner side of the reinforcing rod 1123. Thereby, the interference of the body cover 12 with the driver's legs is avoided. Specifically, when viewed from the height direction of the motorcycle 100, the upper bracket 1121, the lower bracket 1122 and the body cover 12 are arranged to overlap at least partially.

[0052] like Figure 5 As shown, as an implementation, the frame 11 further includes a mounting assembly 114 disposed at the lower portion of the main frame 111. The mounting assembly 114 is arranged in sequence from left to right and is respectively defined as a first mounting member 1141, a second mounting member 1142, a third mounting member 1143 and a fourth mounting member 1144. The first mounting member 1141 and the second mounting member 1142 are fixedly connected, the third mounting member 1143 and the fourth mounting member 1144 are fixedly connected, and the second mounting member 1142 and the third mounting member 1143 are fixedly connected via a lower cross pipe 1145 extending in the width direction.

[0053] like Figure 6As shown, the second mounting member 1142 and the third mounting member 1143 are both fixedly connected to the riser 1113. Preferably, the connection method of the second mounting member 1142 and the riser 1113 is set to be welding, and the connection method of the third mounting member 1143 and the riser 1113 is also set to be welding. The second mounting member 1142 is provided with a positioning portion 1146 that can extend into the riser 1113 at one end close to the riser 1113. The outer contour of the positioning portion 1146 is set to be substantially consistent with the inner contour of the riser 1113, so that the positioning portion 1146 of the second mounting member 1142 is embedded in the riser 1113. By welding around the outer edge of the connection between the riser 1113 and the second mounting member 1142, the error in the welding process is reduced. In addition, by providing the positioning portion 1146 embedded in the riser 1113, the strength of the connection between the second mounting member 1142 and the riser 1113 is increased. Since the connection method between the third mounting member 1143 and the vertical pipe 1113 is basically the same as the connection method between the second mounting member 1142 and the vertical pipe 1113, that is, the third mounting member 1143 is also provided with a positioning portion 1146 that can be embedded in the vertical pipe 1113, it is not repeated here.

[0054] like Figure 7 As shown, as an implementation method, the second mounting member 1142 and the third mounting member 1143 are forgings that are substantially bilaterally symmetrical about the longitudinal plane 101. The second mounting member 1142 and the third mounting member 1143 are both provided with a lower cross tube mounting portion 1147; wherein the lower cross tube mounting portion 1147 can be provided as a through hole or a recessed structure. The two ends of the lower cross tube 1145 are respectively provided in the lower cross tube mounting portions 1147 of the second mounting member 1142 and the third mounting member 1143, and the length L5 of the lower cross tube 1145 extending in the width direction is provided to be less than the maximum spacing L6 of the second mounting member 1142 and the third mounting member 1143 distributed in the width direction. The two ends of the lower cross tube 1145 are respectively welded to the second mounting member 1142 and the third mounting member 1143.

[0055] Further, the first mounting member 1141 is at least partially embedded in the lower cross tube mounting portion 1147 of the second mounting member 1142 and welded to the second mounting member 1142. The fourth mounting member 1144 is at least partially embedded in the lower cross tube mounting portion 1147 of the third mounting member 1143 and welded to the third mounting member 1143.

[0056] The above arrangement can satisfy the positioning of the first mounting member 1141 and the fourth mounting member 1144 in the width direction, so that the error when the first mounting member 1141 and the fourth mounting member 1144 are connected is smaller, the stability of the motorcycle 100 is improved, and the difficulty in the assembly process is lower.

[0057] This application also provides Figure 8In another assembly method of the mounting assembly 114, the second mounting member 1142 and the third mounting member 1143 are both provided with a lower cross tube mounting portion 1147, wherein the lower cross tube mounting portion 1147 is provided as a through hole. The two ends of the lower cross tube 1145 respectively pass through the lower cross tube mounting portions 1147 of the second mounting member 1142 and the third mounting member 1143, and the length L7 of the lower cross tube 1145 extending in the width direction is provided to be greater than the maximum spacing L6 of the second mounting member 1142 and the third mounting member 1143 distributed in the width direction. The lower cross tube 1145 is welded to the second mounting member 1142 and the third mounting member 1143, respectively.

[0058] Further, the first mounting member 1141 can be sleeved on one end of the lower transverse tube 1145, and the first mounting member 1141 is fixedly connected to the second mounting member 1142 by means of circumferential welding at the connection between the first mounting member 1141 and the second mounting member 1142. The fourth mounting member 1144 can be sleeved on the other end of the lower transverse tube 1145, and the fourth mounting member 1144 is fixedly connected to the third mounting member 1143 by means of circumferential welding at the connection between the fourth mounting member 1144 and the third mounting member 1143.

[0059] The above arrangement can satisfy the positioning of the first mounting member 1141 and the fourth mounting member 1144 in the width direction, so that the error when the first mounting member 1141 and the fourth mounting member 1144 are connected is smaller, the stability of the motorcycle 100 is improved, and the difficulty in the assembly process is lower.

[0060] like Figure 5 and Figure 6 As shown, as an implementation, the second mounting member 1142 and the third mounting member 1143 are both provided with an engine mounting portion 1148, a shock absorber mounting portion 1149 and a center support mounting portion 1151. Specifically, the engine mounting portion 1148 is at least partially disposed in a receiving space formed by the main frame 111 and the additional frame 113. The power system 15 includes an engine (not shown) for driving the travel assembly 14, and the engine is fixedly connected to the main frame 111 through the engine mounting portion 1148.

[0061] Furthermore, the shock absorber mounting portion 1149 is arranged at the rear of the lower cross tube mounting portion 1147, and the suspension assembly 13 further includes a shock absorber assembly 132, and the shock absorber mounting portion 1149 is used to connect the shock absorber assembly 132 of the motorcycle 100. In addition to being connected to the shock absorber mounting portion 1149, the shock absorber assembly 132 is also rotatably connected to the upper cross tube 1114 and the rear flat fork 131 respectively. Since the shock absorber mounting portion 1149 is arranged between the center support mounting portion 1151 and the lower cross tube 1145, the distance between the shock absorber mounting portion 1149 and the lower cross tube 1145 is shorter, so that the moment between the shock absorber assembly 132 and the main frame 111 is smaller during operation, and the second mounting member 1142 and the third mounting member 1143 can withstand greater pressure and are not easily deformed under the pressure of the shock absorber assembly 132. The service life of the second mounting member 1142 and the third mounting member 1143 is extended.

[0062] As an implementation, the center support mounting portion 1151 is disposed at the rear lower portion of the shock absorber mounting portion 1149, and the frame 11 includes a center support 116 for supporting the motorcycle 100, and the center support 116 is connected to the main frame 111 through the center support mounting portion 1151. The center support 116 is at least partially disposed in the center support mounting portion 1151 and can rotate around the axis of the center support mounting portion 1151. This prevents the center support 116 from interfering with the shock absorber assembly 132 during the rotation process.

[0063] It should be noted that the engine mounting portion 1148 , the shock absorber mounting portion 1149 and the center support mounting portion 1151 can all be configured as through holes to facilitate connection of the engine, the center support 116 and the shock absorber assembly 132 to the mounting assembly 114 .

[0064] like Figure 6 As shown, when the motorcycle 100 is placed on the ground through the center support 116, in order to prevent the elastic force of the spring connected to the center support 116 from forcing the center support 116 to reset, a center support stopper 1152 is provided on the second mounting member 1142 or the third mounting member 1143, and the center support stopper 1152 protrudes toward the outside of the motorcycle 100. When the motorcycle 100 is placed on the ground through the center support 116, at least a portion of the center support 116 abuts against the center support stopper 1152.

[0065] In summary, the engine mounting portion 1148, the lower cross tube mounting portion 1147, the shock absorber mounting portion 1149 and the center support mounting portion 1151 are respectively integrated and arranged on the second mounting member 1142 and the third mounting member 1143. The welding process when fixing the center support 116, the shock absorber assembly 132 and the engine is reduced, and fewer welding processes can reduce the accumulated tolerance of the center support 116, the shock absorber assembly 132 and the engine during the assembly process, thereby making the motorcycle 100 have better stability.

[0066] like Fig. 9 and Fig.10 As shown, the present application also provides another embodiment of the mounting assembly 114, including a first mounting member 1141, a second mounting member 1142, a third mounting member 1143 and a fourth mounting member 1144 which are the same as those in the above embodiment and are sequentially distributed along the width direction. The mounting assembly 114 includes a first sheet metal member 1154 and a second sheet metal member 1155, and the first sheet metal member 1154 and the second sheet metal member 1155 are distributed along the width direction of the motorcycle 100. One end of the first sheet metal member 1154 is detachably connected to the mounting assembly 114, and the other end of the first sheet metal member 1154 is rotatably connected to the center support 116; one end of the second sheet metal member 1155 is detachably connected to the mounting assembly 114, and the other end of the second sheet metal member 1155 is rotatably connected to the center support 116. By integrating the first sheet metal 1154, the second sheet metal 1155 and the center support 116, during the assembly process of the center support 116 and the main frame 111, the small group assembly of the center support 116 and its related components can be completed in advance, and then the center support 166 and its related components can be connected to the main frame 111, thereby reducing the difficulty of installing the center support 116.

[0067] Specifically, the second mounting member 1142 and the third mounting member 1143 are both integrated with an engine mounting portion 1148, a lower cross tube mounting portion 1147, and a shock absorber mounting portion 1149. The second mounting member 1142 is pre-set with a corresponding mounting portion for connecting to the first sheet metal member 1154, and the second mounting member 1142 and the first sheet metal member 1154 are detachably connected; the fourth mounting member 1144 is also pre-set with a corresponding mounting portion for connecting to the second sheet metal member 1155, and the fourth mounting member 1144 and the second sheet metal member 1155 are detachably connected.

[0068] Furthermore, the first sheet metal part 1154 is disposed on the outer side of the second mounting part 1142, and the second sheet metal part 1155 is disposed on the outer side of the fourth mounting part 1144, thereby improving the convenience of refitting the center support 116. It should be noted that the outer sides of the second mounting part 1142 and the fourth mounting part 1144 are both away from the longitudinal plane 101.

[0069] The above arrangement makes the disassembly of the center support 116 more convenient, which helps to reduce the difficulty of modification and maintenance of the center support 116 .

[0070] like Fig.11As shown, as an implementation method, a center support rotating member 1161 is provided between the center support 116 and the first sheet metal member 1154, and the center support rotating member 1161 can be integrated on the center support 116 or the first sheet metal member 1154. When viewed from a perspective perpendicular to the width direction of the motorcycle 100, the center support rotating member 1161 is substantially in the shape of an "I". Taking the center support rotating member 1161 provided on the center support 116 as an example, the first sheet metal member 1154 is sleeved on the center support rotating member 1161, and the first sheet metal member 1154 can rotate around the axis of the center support rotating member 1161, so that the center support 116 can switch between the storage state and the open state. Furthermore, a shaft sleeve 1161a is provided between the first sheet metal part 1154 and the middle support rotating part 1161, and the shaft sleeve 1161a is sleeved on the middle support rotating part 1161. The shaft sleeve 1161a reduces the wear between the middle support rotating part 1161 and the first sheet metal part 1154, and improves the smoothness of the middle support 116 during rotation. It can be understood that a corresponding middle support rotating part 1161 is also provided between the second sheet metal part 1155 and the middle support 116, which will not be described in detail here.

[0071] Specifically, the middle support limiter 1152 is disposed on the first sheet metal part 1154 and / or the second sheet metal part 1155. An elastic member 1156 is disposed between the middle support 116 and the first sheet metal part 1154, one end of the elastic member 1156 is fixedly connected to the middle support 116, and the other end of the elastic member 1156 is fixedly connected to the first sheet metal part 1154. An elastic member 1156 is also disposed between the middle support 116 and the second sheet metal part 1155, one end of the elastic member 1156 is fixedly connected to the middle support 116, and the other end of the elastic member 1156 is fixedly connected to the second sheet metal part 1155.

[0072] Through the above arrangement, the center support 116 and its related parts can be assembled by group assembly, and then connected to the installation assembly 114. It can be understood that since the number of the center support 116 and its related parts is large and the assembly is relatively cumbersome, the above arrangement can reduce the complexity of the connection between the center support 116 and the installation assembly 114, thereby improving the assembly efficiency of the center support 116 and its related parts.

[0073] like Fig.12 As shown, as an implementation, the power system 15 also includes an exhaust mechanism 151 extending basically along the length direction of the motorcycle 100, the exhaust mechanism 151 is at least partially disposed on the fourth mounting member 1144, and the exhaust mechanism 151 is also at least partially disposed between the first sheet metal member 1154 and the second sheet metal member 1155.

[0074] Specifically, a reference plane 106 perpendicular to the height direction of the motorcycle 100 is defined, and the projection of the frame 11 along the height direction on the reference plane 106 and the projection of the exhaust mechanism 16 along the height direction on the reference plane 106 are set to substantially overlap. Thus, the exhaust mechanism 16 is set closer to the inside of the frame 11, avoiding the excessive temperature of the pipe of the exhaust mechanism 16 from causing damage to the driver, thereby improving the safety of the motorcycle 100. In addition, the exhaust mechanism 16 set closer to the inside of the frame 11 can make the overall structure of the motorcycle 100 more compact.

[0075] like Fig.13 and Fig.14 As shown, as an implementation, the shock absorbing assembly 132 includes a rear shock absorber 1321, a triangular rocker arm 1322 and a connecting rod 1323. The shock absorbing assembly 132 is rotatably connected to the second mounting member 1142 and the third mounting member 1143 respectively through the connecting rod 1323. The triangular rocker arm 1322 includes a connecting rod connecting portion 1322a, a flat fork connecting portion 1322b and a shock absorbing connecting portion 1322c. The triangular rocker arm 1322 is rotatably connected to the connecting rod 1323 through the connecting rod connecting portion 1322a, the triangular rocker arm 1322 is rotatably connected to the rear flat fork 131 through the flat fork connecting portion 1322b, and the triangular rocker arm 1322 is also rotatably connected to the rear shock absorber 1321 through the shock absorbing connecting portion 1322c. Among them, the connecting rod connecting portion 1322a, the flat fork connecting portion 1322b and the shock absorbing connecting portion 1322c are all set as through holes.

[0076] Specifically, the shock-absorbing connection portion 1322c includes adjacent first mounting points 1322d and second mounting points 1322e, and the rear shock absorber 1321 can be rotatably connected to the triangular rocker arm 1322 through any one of the first mounting points 1322d and the second mounting points 1322e. When the rear shock absorber 1321 is connected to the first mounting point 1322d, the height of the seat cushion 121 is the first height; when the rear shock absorber 1321 is connected to the second mounting point 1322e, the height of the seat cushion 121 is the second height. Through the above arrangement, the height adjustment of the seat cushion 121 is achieved, thereby meeting the use requirements of different drivers and improving the driving experience of the driver. It can be understood that in order to achieve the change of the connection position of the rear shock absorber 1321, the rear shock absorber 1321 and the first mounting point 1322d and the second mounting point 1322e are both set to be detachably connected.

[0077] It should be noted that the line connecting the axis of the front wheel 141 and the axis of the rear wheel 142 is defined as the wheel axis of the motorcycle 100; wherein the axis of the two represents the respective rotation center. The height of the seat cushion 121 refers to the distance from the lowest point of the seat cushion 121 to the wheel axis along the height direction of the motorcycle 100.

[0078] Specifically, when the triangular rocker arm 1322, the rear fork 131, the connecting rod 1323 and the rear shock absorber 1321 are all in an installed state, the first mounting point 1322d is arranged at the upper end of the second mounting point 1322e, and the first mounting point 1322d is arranged behind the second mounting point 1322e.

[0079] like Fig.14 As shown, as an optional implementation, the hole spacing L8 between the first mounting point 1322d and the second mounting point 1322e is set to be greater than or equal to 12 mm and less than or equal to 18 mm. Specifically, the hole spacing L8 between the first mounting point 1322d and the second mounting point 1322e is set to be greater than or equal to 14 mm and less than or equal to 16 mm. More preferably, the hole spacing L8 between the first mounting point 1322d and the second mounting point 1322e is set to be greater than or equal to 15 mm. Through the above settings, it is avoided that the hole spacing between the first mounting point 1322d and the second mounting point 1322e is too large, resulting in the seat cushion 121 interfering with the rear fender of the motorcycle 100 during the height adjustment process. In addition, it is avoided that the hole spacing between the first mounting point 1322d and the second mounting point 1322e is too small, resulting in the height adjustment effect of the seat cushion 121 being not obvious enough.

[0080] Optionally, one end of the connecting rod 1323 is detachably connected to the connecting rod connecting portion 1322a. Since the connecting rods 1323 are distributed on the left and right sides of the triangular rocker arm 1322, the convenience of adjusting the connection position of the rear shock absorber 1321 is improved by providing a detachable connecting rod 1323, and when adjusting the connection position of the rear shock absorber 1321 and the triangular rocker arm 1322, the connecting rod 1323 is prevented from interfering with the rear shock absorber 1321.

[0081] like Fig.15 As shown, in this embodiment, the mounting assembly 114 also includes an additional mounting portion 1153, which is provided as a pair and respectively provided on the first mounting member 1141 and the fourth mounting member 1144; wherein the additional mounting portion 1153 can be provided as a through hole or a recessed structure. The additional frame 113 is detachably connected to the mounting assembly 114 via the additional mounting portion 1153. Since the mounting assembly 114 and the riser 1113 are fixedly connected, the additional frame 113 and the main frame 111 can be disassembled. Through the above arrangement, during the modification process of the motorcycle 100, the influence of the disassembly of the additional frame 113 on the main frame 111 is reduced, thereby improving the stability of the motorcycle 100.

[0082] In order to improve the refitability of the motorcycle 100 and reduce the impact on the engine and the main frame 111 during the modification of the motorcycle 100, the present application provides Fig.11The auxiliary frame 113 is detachably connected to the main frame 111 via fasteners, thereby ensuring the stability of the motorcycle 100 after the modification process.

[0083] like Fig.15 As shown, as an implementation method, the main frame 111 also includes a lower main pipe 1117 extending downward from the head pipe 1111. The lowermost end of the lower main pipe 1117 is provided with an engine mounting point 1117a, and the engine is fixedly connected to the main frame 111 through the engine mounting point 1117a. Among them, the engine mounting point 1117a can be set as a through hole. Since the additional frame 113 needs to meet the modification needs of the driver, the additional frame 113 may be frequently disassembled and assembled. The above-mentioned setting can avoid interference with the engine during the disassembly process of the additional frame 113, so that the motorcycle 100 can complete the modification of the additional frame 113 without disassembling the engine, thereby ensuring the stability of the overall structure of the motorcycle 100.

[0084] Specifically, the additional frame 113 is provided with a modification part mounting point 1131 and a guard plate mounting point 1132, and the additional frame 113 can also integrate at least one of a radiator mounting point 1133, a decorative plate mounting point 1134, and a crossbeam mounting point 1135. The above-mentioned mounting points may be provided by punching holes, or by providing sheet metal for connecting corresponding components.

[0085] like Fig.15 As shown, as an implementation, the additional frame 113 includes a first additional mounting member 1136 and a second additional mounting member 1137. The additional frame 113 is detachably connected to the lower main pipe 1117 of the main frame 111 through the first additional mounting member 1136, and the additional frame 113 is detachably connected to the mounting assembly 114 through the second additional mounting member 1137. The first additional mounting member 1136 and the second additional mounting member 1137 are fixedly connected. The first additional mounting member 1136 is configured as a forging. Since the second additional mounting member 1137 is a tubular frame with a substantially annular cross section, the first additional mounting member 1136 can be arranged in the second additional mounting member 1137 in an embedded manner, and the first additional mounting member 1136 and the second additional mounting member 1137 are fixedly connected at the connection point by circumferential welding. The above arrangement improves the connection strength between the first additional mounting member 1136 and the second additional mounting member 1137, and the first additional mounting member 1136 configured as a forging has a higher structural strength, thereby preventing deformation of the connection between the additional frame 113 and the main frame 111 after multiple loading and unloading of the additional frame 113.

[0086] As another optional implementation, the first additional mounting member 1136 is set as a pipe, and the first additional mounting member 1136 is extruded, and the extruded first additional mounting member 1136 is connected to the second additional mounting member 1137 in an embedded manner. Then, the first additional mounting member 1136 and the second additional mounting member 1137 are fixedly connected at the connection point by circumferential welding, thereby reducing the manufacturing difficulty and design cost of the additional frame 113.

[0087] like Fig.15 As shown, specifically, a modification part installation point 1131 is provided on the first additional installation part 1136, and the bumper of the motorcycle 100 (not shown) is connected to the additional frame 113 through the modification part installation point 1131. The modification part installation point 1131 is set as a through hole, and the axis of the modification part installation point 1131 basically extends along the width direction. Since the bumper of the motorcycle 100 has a variety of styles and shapes, in order to meet the use needs of different drivers, by setting the modification part installation point 1131 with an axis extending along the width direction, it is more convenient to install and remove the bumper.

[0088] Furthermore, in addition to the modification part mounting point 1131, the first additional mounting part 1136 is also provided with a radiator mounting point 1133, and the radiator mounting point 1133 is set as a through hole. The power system 15 includes a radiator 152 arranged on the front side of the engine, and the radiator 152 is detachably connected to the additional frame 113 through the radiator mounting point 1133. The radiator 152 is at least partially arranged on the main frame 111, and the radiator 152 is rotatably connected to the main frame 111. The lower part of the radiator 152 is connected to the additional frame 113 through the radiator mounting point 1133, and while limiting the radiator 152, the connection strength between the main frame 111 and the additional frame 113 is strengthened through the radiator 152.

[0089] More specifically, in order to prevent the radiator 152 and the bumper from interfering with each other during installation, when the radiator mounting point 1133 is configured as a through hole, the axis of the radiator mounting point 1133 extends substantially in the length direction.

[0090] like Fig.15 As shown, as an implementation, the guard plate mounting point 1132, the decorative plate mounting point 1134 and the crossbeam mounting point 1135 are integrated and arranged on the second additional mounting member 1137, and the above three are all arranged as sheet metal connected to the second additional mounting member 1137. At least one guard plate mounting point 1132 is arranged on the second additional mounting member 1137. The body cover 12 includes a lower guard plate 122 arranged on the lower side of the engine, and the lower guard plate 122 is detachably connected to the second additional mounting member 1137 through the guard plate mounting point 1132.

[0091] Specifically, at least one decorative panel mounting point 1134 is disposed on the second additional mounting member 1137. The body cover 12 includes decorative panels (not shown) disposed on the left and right sides of the motorcycle 100, and the decorative panels are detachably connected to the second additional mounting member 1137 via the decorative panel mounting points 1134.

[0092] Furthermore, the additional frame 113 further includes a crossbeam 1138 extending in a substantially width direction, and a crossbeam mounting point 1135 is arranged in the middle of the second additional mounting member 1137. The second additional mounting member 1137 is arranged as a paired and symmetrically distributed tubular frame, and the crossbeam 1138 is detachably connected to the second additional mounting member 1137 through the crossbeam mounting point 1135, and the crossbeam 1138 is arranged between the second additional mounting members 1137 distributed in pairs, thereby increasing the overall structural strength of the additional frame 113. Through the above arrangement, since the left and right pairs of additional frames 113 are connected by the crossbeam 1138, when the additional frame 113 is loaded, the crossbeam 1138 can be disassembled to reduce the space occupied by the additional frame 113, so that the loading of the additional frame 113 is more convenient, thereby improving the utilization rate of the loading space when packing the additional frame 113.

[0093] As another optional implementation, the second additional mounting member 1137 is integrated with a guard plate mounting point 1132 and a decorative panel mounting point 1134. While meeting the modification requirements of the motorcycle 100 and the structural strength of the additional frame 113 itself, the weight of the motorcycle 100 can be reduced by removing the crossbeam 1138 and the crossbeam mounting point 1135.

[0094] In summary, by providing a detachable additional frame 113, and integrating the modification part mounting point 1131, the guard plate mounting point 1132, the radiator mounting point 1133, the decorative plate mounting point 1134 and / or the crossbeam mounting point 1135 on the additional frame 113, the modifiability of the motorcycle 100 is improved while ensuring the stability of the motorcycle 100, so that the driver has a better vehicle experience.

[0095] like Fig.16 As shown, as an implementation, the motorcycle 100 further includes a pedal assembly 17 for the driver to step on, and the pedal assembly 17 is at least partially disposed on the main frame 111. The pedal assembly 17 is respectively disposed on the left and right sides of the motorcycle 100, that is, the pedal assembly 17 is respectively fixedly connected to the first mounting member 1141 and the fourth mounting member 1144. The pedal assembly 17 includes a pedal seat 171 and a pedal rubber 172 at least partially disposed on the pedal seat 171. The pedal rubber 172 is penetrated through the pedal seat 171 along the height direction of the motorcycle 100 and is clamped with the pedal seat 171.

[0096] like Fig.16 and Fig.17 As shown, specifically, a pedal stop hole 1711 penetrating the pedal seat 171 is provided on the bottom surface of the pedal seat 171, and the pedal rubber 172 includes a rubber extension portion 1721 extending along the axial direction of the pedal stop hole 1711, and the rubber extension portion 1721 is at least partially penetrated in the pedal stop hole 1711. The length of the rubber extension portion 1721 extending along the axial direction of the pedal stop hole 1711 is limited to L9, and the thickness of the pedal stop hole 1711 extending along its own axial direction is limited to L10. The length L9 of the rubber extension portion 1721 is set to be greater than the thickness L10 of the pedal stop hole 1711. The above-mentioned setting limits the displacement of the pedal rubber 172 in any direction perpendicular to the axial direction of the pedal stop hole 1711, reduces the number of parts used to position and fix the pedal rubber 172, thereby reducing the difficulty of loading and unloading the pedal rubber 172, and the cost of the pedal assembly 17 is lower.

[0097] like Fig.16 As shown, a rubber stopper 1722 is formed around the outer edge of the rubber extension 1721 and is in contact with the pedal seat 171. The outline of the rubber stopper 1722 is basically set to be circular, and the length of the rubber stopper 1722 along its own radial distribution is limited to L11, and the length of the pedal stopper hole 1711 along its own radial distribution is limited to L12. Among them, the length L11 of the rubber stopper 1722 is set to be greater than the length L12 of the pedal stopper hole 1711. Through the above-mentioned setting, the pedal rubber 172 is clamped with the pedal seat 171, which reduces the difficulty of installing the pedal rubber 172 and facilitates the removal of the pedal rubber 172.

[0098] It is understandable that, since the pedal rubber 172 is made of rubber material, the pedal rubber 172 has a certain degree of ductility. During the disassembly process of the pedal rubber 172, the rubber limiting portion 1722 is deformed by pressing the rubber limiting portion 1722, that is, the deformed rubber limiting portion 1722 can at least pass through the pedal limiting hole 1711. Further, since the contour of the rubber limiting portion 1722 is basically set to be circular, the rubber limiting portion 1722 can obtain a substantially consistent force sufficient to pass through the pedal limiting hole 1711 in any direction, thereby making the disassembly of the pedal rubber 172 more convenient.

[0099] like Fig.16 As shown, more specifically, the end surface of the rubber stopper 1722 facing the pedal seat 171 is set as a plane, so that when the pedal rubber 172 is engaged with the pedal seat 171, the connection between the pedal rubber 172 and the pedal seat 171 is more stable. The end surface of the rubber stopper 172 away from the pedal seat 171 is set as an arc surface, so that the installation of the pedal rubber 172 and the pedal seat 171 is more convenient during the installation process of the pedal rubber 172.

[0100] Since about 60% of the driving scenarios of the motorcycle 100 proposed in this application are off-road, in this riding scenario, the driver often does not carry the matching disassembly tools. The above arrangement enables the pedal rubber 172 to be disassembled without tools, thereby improving the convenience of disassembly of the pedal rubber 172.

[0101] like Fig.16 As shown, as an implementation method, a pedal limiting portion 1712 is provided on the side wall of the pedal seat 171 away from the limiting hole, and a rubber limiting hole 1723 is provided on the pedal rubber 172 for the pedal limiting portion 1712 to be embedded. When the pedal rubber 172 is connected to the pedal seat 171, the pedal limiting portion 1712 is inserted into the rubber limiting hole 1723, and the pedal rubber 172 is limited by the cooperation between the pedal limiting portion 1712 and the rubber limiting hole 1723. Then, the rubber extension portion 1721 is inserted into the pedal limiting hole 1711, and abuts against the pedal seat 171 through the rubber limiting portion 1722. The above-mentioned installation method realizes the positioning and installation of the pedal rubber 172 through the ductility of the pedal rubber 172 itself, reduces the number of fasteners required to fix the pedal rubber 172, reduces the difficulty of assembling the pedal rubber 172, and requires fewer fasteners to achieve the purpose of reducing the cost of the pedal assembly 17.

[0102] Specifically, when the pedal assembly 17 is in the open state, the pedal seat 171 extends substantially along the width direction of the motorcycle 100, and the pedal limiting portion 1712 and the pedal limiting hole 1711 are substantially distributed at both ends of the pedal seat 171 along the width direction, thereby preventing the uneven distribution of force when the driver steps on the pedal assembly 17, which causes one side of the pedal rubber 172 to be lifted, so that the pedal rubber 172 is more stable when connected to the pedal seat 171. The open state of the pedal assembly 17 refers to a state in which the driver can step on it, and the corresponding pedal assembly 17 also has a storage state folded inward. In addition, in order to improve the limiting effect of the pedal rubber 172, the number of the pedal limiting hole 1711 is set to at least one, and the number of the rubber extension portion 1721 is limited to be less than or equal to the number of the pedal limiting holes 1711.

[0103] In this embodiment, the footrest assembly 17 includes a left footrest 173 and a right footrest 174 respectively arranged on the left and right sides of the motorcycle 100, and the structures of the left footrest 173 and the right footrest 174 are basically the same, so that the left footrest 173 and the right footrest 174 can be replaced with each other. It can be understood that the above arrangement reduces the number of molds required for producing the footrest assembly 17, thereby reducing the production cost of the footrest assembly 17.

[0104] It can be understood that the above arrangement reduces the number of fasteners required to fix the pedal rubber 172 , and no corresponding tools are required during the installation and removal of the pedal rubber 172 , thereby improving the convenience of installing and removing the pedal rubber 172 .

[0105] like Fig.18 As shown, as an implementation, the motorcycle 100 further includes a brake system 18, which includes a brake pedal 181 and a pedal bracket 182 that can be stepped on by the driver, and the brake pedal 181 is rotatably connected to the pedal bracket 182. The driver steps on the pedal bracket 182, so that the pedal bracket 182 drives the brake pedal 181 to rotate, thereby achieving a braking operation of the motorcycle 100.

[0106] Specifically, the brake pedal rod 181 extends substantially along the length direction of the motorcycle 100, and a pedal rod mounting portion 1811 for connecting to a pedal bracket 182 is provided on the brake pedal rod 181. A pedal connecting portion 1821 for connecting to the brake pedal rod 181 is provided at one end of the pedal bracket 182. When the pedal bracket 182 is connected to the brake pedal rod 181, the pedal rod mounting portion 1811 is at least partially disposed in a space formed by the pedal connecting portion 1821. The fastener 183 is sequentially disposed through the pedal connecting portion 1821 and the pedal rod mounting portion 1811, and the axis of the fastener 183 extends in the height direction. The pedal bracket 182 can rotate relative to the brake pedal rod 181 with the axis of the fastener 183 as the rotation axis.

[0107] Furthermore, a pedal rod elastic member 184 is provided at the connection between the pedal rod mounting portion 1811 and the pedal connecting portion 1821, and the pedal rod elastic member 184 is sleeved on the fastener 183; wherein the pedal rod elastic member 184 can be provided as a torsion spring or a compression spring. One end of the pedal rod elastic member 184 abuts against the pedal connecting portion 1821, and the other end of the pedal rod elastic member 184 abuts against the pedal rod mounting portion 1811. When the pedal bracket 182 rotates around the axis of the fastener 183, the pedal rod elastic member 184 abutting against the pedal connecting portion 1821 is deformed by force. At this time, the pedal bracket 182 is in a folded state. The elastic force of the pedal rod elastic member 184 can force the pedal bracket 182 to reset after the pedal bracket 182 rotates, thereby changing the pedal bracket 182 from a folded state to an unfolded state.

[0108] More specifically, a pedal stopper 1812 is further provided at the rear of the brake pedal 181, and the pedal stopper 1812 is provided at the rear of the pedal mounting portion 1811. When the pedal bracket 182 is in the unfolded state, the pedal bracket 182 abuts against the pedal stopper 1812. When the elastic force of the pedal elastic member 184 drives the pedal bracket 182 to reset, the pedal bracket 182 is limited to rotate around the axis of the fastener 183 by the pedal stopper 1812, thereby avoiding damage to the pedal bracket 182 and the pedal elastic member 184 during the reset process.

[0109] By the above arrangement, when the motorcycle 100 turns over, the pedal bracket 182 can be folded under the pressure of the ground to avoid damage to the pedal bracket 182. By arranging the pedal rod elastic member 184 so that the pedal bracket 182 has the function of automatically resetting when the pressure disappears, the service life of the brake pedal 181 is extended.

[0110] like Fig.19 As shown, as an implementation, the motorcycle 100 further includes a shift system 19, which is at least partially disposed in front of the pedal assembly 17. The shift system 19 includes a shift pedal 191 and a shift connecting rod 192 that can be stepped on by the driver, and the shift pedal 191 and the shift connecting rod 192 are configured to be rotatably connected.

[0111] Specifically, a reset member 193 is provided at the connection between the shift pedal 191 and the shift connecting rod 192, one end of the reset member 193 abuts against the shift connecting rod 192, and the other end of the reset member 193 abuts against the shift pedal 191; wherein the reset member 193 is configured as at least one of a torsion spring and a compression spring. The shift pedal 191 and the shift connecting rod 192 are riveted by a fastener 194, and the fastener 194 is inserted into the reset member 193. When the shift pedal 191 is connected to the shift connecting rod 192, the shift pedal 191 can rotate around the axis of the fastener 194. Therefore, when the motorcycle 100 falls over, the shift pedal 191 can rotate around the axis of the fastener 194 to a retracted position under the pressure received. At this time, the reset member 193 is deformed due to the rotation of the shift pedal 191, and the elastic potential energy gathered by the reset member 193 forces the shift pedal 191 to return to the open position when the pressure disappears.

[0112] Through the above arrangement, the gear shift pedal 191 is made more flexible and can be automatically retracted when the motorcycle 100 falls over, thereby avoiding damage to the gear shift system 19.

[0113] In the description of the present application, it should be understood that the description “a component is located on the inner side of another component” means that one component is located on a side of another component away from the body cover or the outer surface of the motorcycle.

[0114] In the description of this application, it needs to be understood that the term "length direction" refers to the front-to-back direction parallel to the motorcycle driver's vehicle when the motorcycle driver is in the driving state, the term "width direction" refers to the left-to-right direction parallel to the motorcycle driver's vehicle when the motorcycle driver is in the driving state, and the term "height direction" refers to the up-and-down direction parallel to the motorcycle driver's vehicle when the motorcycle driver is in the driving state.

[0115] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
