[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Such as Figure 1A motorcycle 100 is shown. The motorcycle 100 includes a frame 11, a running system 12, a power assembly 13, a power battery 14, and a suspension system 15. The frame 11 constitutes the basic framework of the motorcycle 100 and is used to support the running system 12, the power assembly 13, the power battery 14, and the suspension system 15. The running system 12 includes a front wheel 121 and a rear wheel 122. The power assembly 13 is drivingly connected to at least one of the front wheel 121 and the rear wheel 122, so that the front wheel 121 and the rear wheel 122 can achieve the movement of the motorcycle 100. Both the power assembly 13 and the power battery 14 are at least partially disposed on the frame 11. The power battery 14 is electrically connected to the power assembly 13, and the power battery 14 is used to provide energy for the power assembly 13. The suspension system 15 is connected to the frame 11, and both the front wheel 121 and the rear wheel 122 are connected to the frame through the suspension system 15. To clearly illustrate the technical solution of the present application, the front, rear, left, right, up, and down as shown in Figure 1 are also defined. It can be understood that in the embodiments of the present application, the front-rear direction refers to the length direction of the motorcycle 100, the left-right direction refers to the width direction of the motorcycle 100, and the up-down direction refers to the height direction of the motorcycle 100. It can be understood that along the up-down direction of the motorcycle 100, the running system 12 is at least partially disposed below the frame 11.

[0030] As Figure 2 and Figure 3As shown, the vehicle frame 11 includes a main vehicle frame 111 and a front support 112. The front support 112 is located on the front side of the main vehicle frame 111 and is fixedly connected to the main vehicle frame 111. Specifically, the main vehicle frame 111 includes an upper support frame 1111, a front mounting frame 1112, a rear mounting frame 1113, and a lower support frame 1114. When observed in the width direction of the motorcycle 100, the upper support frame 1111 is substantially in a triangular frame structure and is substantially located at the uppermost part of the vehicle frame 11. Therefore, the upper support frame 1111 basically constitutes the main supporting part of the beam frame of the motorcycle 100. The lower support frame 1114 includes a plurality of pipe fittings extending in the front-rear direction, and the plurality of pipe fittings are substantially distributed in the width direction and are respectively connected to one or more pipe fittings extending in the width direction. The lower support frame 1114 is substantially located at the lowermost part of the vehicle frame 11. Therefore, the lower support frame 1114 basically constitutes the main supporting part of the chassis of the motorcycle 100. The front mounting frame 1112 is substantially located on the front side of the vehicle frame 11. The front mounting frame 1111 includes a plurality of pipe fittings extending substantially in the up-down direction, and the plurality of pipe fittings are substantially distributed in the width direction, so that the upper side of the front mounting frame 1112 is fixedly connected to the front side of the upper support frame 1111, and the lower side of the front mounting frame 1112 is integrally formed with the front side of the lower support frame 1114. The rear mounting frame 1113 is located on the rear side of the front mounting frame 1112. The rear mounting frame 1113 includes a plurality of pipe fittings extending substantially in the up-down direction, and the plurality of pipe fittings are substantially distributed in the width direction. The upper side of the rear mounting frame 1113 is fixedly connected to the rear side of the upper support frame 1111, and the lower side of the rear mounting frame 1113 is fixedly connected to the rear side of the lower support frame 1114. Through the above arrangement, the upper support frame 1111, the front mounting frame 1112, the rear mounting frame 1113, and the lower support frame 1114 are connected to each other to form a stable whole. This arrangement can achieve the light weight of the whole vehicle and the maximization of the installation space while ensuring the strength of the main vehicle frame 111. It should be noted that the upper support frame 1111, the front mounting frame 1112, the rear mounting frame 1113, and the lower support frame 1114 are connected to each other to form a main accommodation space 101, that is, the main vehicle frame 111 surrounds and forms the main accommodation space 101. The main vehicle frame 111 is used to support the body components, and the main accommodation space 101 is used to accommodate the body components. In this application, the power assembly 13 and the power battery 14 are both connected to the main vehicle frame 111, and the power assembly 13 and the power battery 14 are both at least partially located in the main accommodation space 101.

[0031] As Figure 2As shown, as an implementation, the suspension system 15 includes a front suspension 151. The front suspension 151 is connected to the front bracket 112 and is located in front of the main frame 111. The power assembly 13 includes a drive motor 131. Both the drive motor 131 and the power battery 14 are located behind the front suspension 151, and both the drive motor 131 and the power battery 14 are connected to the main frame 111. Specifically, the front side of the power battery 14 is connected to the front mounting bracket 1112, the rear side of the power battery 14 is connected to the rear mounting bracket 1113, the upper side of the power battery 14 is connected to the upper support bracket 1111, the lower side of the power battery 14 is connected to the lower support bracket 1114. The power battery 14 includes a battery opening 141. The drive motor 131 is located within the battery opening 141. The drive motor 131 is at least partially connected to the main frame 111 and is drivingly connected to at least one of the front wheel 121 and the rear wheel 122, so that the drive motor 131 can provide kinetic energy for the front wheel 121 and / or the rear wheel 122. More specifically, the drive motor 131 is located within the main accommodation space 101. The power battery 14 is at least partially disposed around the drive motor 131 and is electrically connected to the drive motor 131, so that the power battery 14 can supply electrical energy to the drive motor 131. Through the above arrangement, the electrical energy of the power battery 14 can be converted into the kinetic energy of the drive motor 131, and the kinetic energy can be transmitted to the front wheel 121 and / or the rear wheel 122 to realize the movement of the motorcycle 100. More specifically, when observed from the height direction of the motorcycle 100, the power battery 14 and the drive motor 131 at least partially overlap. When observed from the length direction of the motorcycle 100, the power battery 14 and the drive motor 131 at least partially overlap. Through the above arrangement, both the power battery 14 and the drive motor 131 are within the main accommodation space 101, and the power battery 14 and the drive motor 131 are structurally compact and do not interfere with each other, which is beneficial to improving the structural compactness of the power battery 14 and the drive motor 131, and thus beneficial to improving the structural compactness of the motorcycle 100. At the same time, the centers of gravity of the power battery 14 and the drive motor 131 are concentrated and are basically located at the horizontal center position of the motorcycle 100, which is beneficial to improving the stability of the motorcycle 100. In addition, the drive motor 131 is disposed within the battery opening 141 and is connected to the main frame 111, so that the power battery 14 can protect the drive motor 131, which is beneficial to extending the service life of the drive motor 131.

[0032] As an implementation, a longitudinal plane 102 perpendicular to the width direction of the motorcycle 100 is defined. The longitudinal plane 102 basically bisects the motorcycle 100, that is, the motorcycle 100 is basically symmetrically arranged with respect to the longitudinal plane 102. The projected area of the main accommodation space 101 on the longitudinal plane 102 in the width direction of the motorcycle 100 is set as the first projected plane, and the sum of the projected areas of the drive motor 131 and the power battery 14 on the longitudinal plane 102 in the width direction of the motorcycle 100 is set as the second projected plane. The ratio of the first projected plane to the second projected plane is greater than or equal to 1.02 and less than or equal to 1.48. Specifically, the ratio of the first projected plane to the second projected plane is greater than or equal to 1.12 and less than or equal to 1.35. More specifically, the ratio of the first projected plane to the second projected plane is 1.23. Through the above settings, it is possible to avoid the situation where the occupancy rate of the drive motor 131 and the power battery 14 in the main accommodation space 101 is too small due to the excessive ratio of the first projected plane to the second projected plane, so as to prevent the excessive waste of the main accommodation space 101, which is beneficial to improving the space utilization rate of the main frame 111; and it is also possible to avoid the situation where the drive motor 131 and the power battery 14 occupy a large main accommodation space 101 due to the too small ratio of the first projected plane to the second projected plane, so as to prevent interference between the drive motor 131 and the power battery 14, which is beneficial to improving the layout rationality of the power battery 14 and the drive motor 131.

[0033] As an implementation, the power battery 14 includes a first battery body 142 that at least partially extends along the length direction of the motorcycle 100, and the power battery 14 further includes a second battery body 143 that at least partially extends along the height direction of the motorcycle 100. The first battery body 142 and the second battery body 143 at least partially surround the drive motor 131. In this embodiment, the first battery body 142 and the second battery body 143 are at least partially connected to form a battery opening 141, that is, the first battery body 142 and the second battery body 143 can be fixedly connected or integrally arranged, which is beneficial to improving the structural strength of the power battery 14. Specifically, when the first battery body 142 is located at the upper end of the second battery body 143, the drive motor 131 is located at the front side or the rear side of the second battery body 143. As another alternative implementation, when the first battery body 142 is located at the lower end of the second battery body 143, the drive motor 131 is located at the front side or the rear side of the second battery body 143. It should be noted that the first battery body 142 and the second battery body 143 can be set according to actual needs to meet the stable connection between the power battery 14 and the main frame 111.

[0034] As an implementation, the powertrain 13 further includes a motor controller 132. The motor controller 132 and the drive motor 131 are distributed along the height direction of the motorcycle 100, and the motor controller 132 is disposed between the first battery body 142 and the drive motor 131. Specifically, the motor controller 132 is located within the battery opening 141, and the motor controller 132 is detachably connected to the drive motor 131 in a fastener connection manner. Through the above arrangement, the drive motor 131 and the power battery 14 are arranged around the motor controller 132, which is beneficial to protecting the motor controller 132. At the same time, the motor controller 132 is disposed close to the power battery 14 to facilitate the electrical connection between the motor controller 132 and the power battery 14, thereby being beneficial to improving the structural compactness of the powertrain 13.

[0035] As an implementation, the projection of the axis of the drive motor 131 on the longitudinal plane 102 along the width direction of the motorcycle 100 is the first projection point, where the axis of the drive motor 131 refers to the axis of the output shaft of the drive motor 131. The projection of the center of gravity of the motor controller 132 on the longitudinal plane 102 along the width direction of the motorcycle 100 is the second projection point, where the motor controller 132 is basically arranged in a cuboid structure, and the center of gravity of the motor controller 132 refers to the geometric center of the cuboid. The projection of the axis of the rear wheel 122 on the longitudinal plane 102 along the width direction of the motorcycle 100 is the third projection point. The connection line between the first projection point and the third projection point is set as the first connection line L1, and the connection line between the second projection point and the third projection point is set as the second connection line L2. The ratio of the first connection line L1 to the second connection line L2 is set to be greater than or equal to 0.69 and less than or equal to 0.98. Specifically, the ratio of the first connection line L1 to the second connection line L2 is set to be greater than or equal to 0.76 and less than or equal to 0.91. More specifically, the ratio of the first connection line L1 to the second connection line L2 is set to 0.87. Through the above arrangement, it is possible to avoid the drive motor 131 being arranged too far forward due to the ratio of the first connection line L1 to the second connection line L2 being too large, so as to prevent the center of gravity of the motorcycle 100 from being unbalanced, and thus be beneficial to improving the stability of the motorcycle 100. Also, it is possible to avoid the motor controller 132 occupying a large main accommodation space 101 due to the ratio of the first connection line L1 to the second connection line L2 being too small, so as to prevent the motor controller 132 from interfering with the arrangement of the power battery 14, thereby being beneficial to improving the layout rationality and space utilization rate of the motorcycle 100.

[0036] As an implementation, the powertrain 13 further includes a speed reducer 133. The speed reducer 133 is located within the battery opening 141 and is fixedly connected to the drive motor 131. The drive motor 131, the motor controller 132, and the speed reducer 133 are integrally arranged. Specifically, the drive motor 131, the motor controller 132, and the speed reducer 133 can be fixedly connected to form an integrated structure. Through the above arrangement, the structures of the drive motor 131, the motor controller 132, and the speed reducer 133 can be made compact and the connection stable, which is conducive to improving the structural compactness and connection stability of the powertrain 13, facilitating the assembly of the powertrain 13 with the main frame 111, and further improving the assembly performance of the motorcycle 100.

[0037] In this embodiment, there is a gap 1411 between the battery opening 141 and the drive motor 131, and the width D1 of the gap 1411 is set to be greater than or equal to 1.2 mm and less than or equal to 3.6 mm. Specifically, the width D1 of the gap 1411 is set to be greater than or equal to 1.6 mm and less than or equal to 2.9 mm. More specifically, the width D1 of the gap 1411 is set to 2.4 mm. Through the above arrangement, it is possible to avoid wasting the main accommodation space 101 due to the excessive width D1 of the gap 1411, which is conducive to improving the space utilization rate of the motorcycle 100; and it is also possible to avoid the adverse effect on the heat dissipation of the drive motor 131 due to the too small width D1 of the gap 1411, which is conducive to improving the heat dissipation performance of the drive motor 131. At the same time, the power battery 14 is not heat-resistant, which is also conducive to extending the service life of the power battery 14.

[0038] As an implementation, the suspension system 15 further includes a rear swing arm 152. An installation point 1113a is provided on the rear mounting bracket 1113. The rear swing arm 152 is used to connect the rear mounting bracket 1113 and the rear wheel 122. A fastener passes through the drive motor 131, the rear swing arm 152, and the installation point 1113a, enabling the rear swing arm 152 to be rotatably connected to the main frame 111 and the drive motor 131 to be fixedly connected to the rear mounting bracket 1113. Specifically, one end of the rear swing arm 152 is rotatably connected to the rear mounting bracket 1113, the other end of the rear swing arm 152 is connected to the rear wheel 122, the rear side of the drive motor 131 is fixedly connected to the rear mounting bracket 1113, and at least a part of the rear swing arm 152 is arranged at the rear side of the rear mounting bracket 1113. Through the above arrangement, both the rear swing arm 152 and the drive motor 131 can be connected to the installation point 1113a, thereby reducing the number of arrangements of the installation point 1113a on the frame 11, which is conducive to improving the assembly performance of the main frame 111, the drive motor 131, and the rear swing arm 152. At the same time, the number of fasteners used is reduced, which is also conducive to improving the space utilization rate of the motorcycle 100.

[0039] As Figure 2 and Figure 3As shown, as an implementation manner, a motor mounting portion 1114a is provided on the front side of the lower support frame 1114, a motor connecting frame 113 is provided on the rear side of the lower support frame 1114, a first connecting portion 1311 and a second connecting portion 1312 are provided on the lower side of the driving motor 131, the motor mounting portion 1114a is connected to the first connecting portion 1311, and the motor connecting frame 113 is connected to the second connecting portion 1312, so that the driving motor 131 is connected to the lower support frame 1114. Through the above arrangement, the driving motor 131 can be stably connected to the lower support frame 1114, which is beneficial to improving the connection stability between the driving motor 131 and the lower support frame 1114, and further beneficial to improving the structural stability of the motorcycle 100.

[0040] As Figure 3 As shown, as an implementation manner, the power battery 14 includes a battery housing 144 and a plurality of connecting portions 1441 provided on the battery housing 144, and the connecting portions 1441 extend towards the frame 11. The battery housing 144 and the connecting portions 1441 can be integrally formed or fixedly connected. A connecting member 1115 corresponding to the connecting portion 1441 is provided on the main frame 111. The connecting member 1115 extends from the frame 11 towards the main accommodation space 101. The connecting portion 1441 is fixedly connected to the connecting member 1115, so that the power battery 14 is fixedly connected to the frame 11, and there is a gap between the power battery 14 and the frame 11. Along the width direction of the motorcycle 100, at least a part of the connecting member 1115 overlaps with the main accommodation space 101. Among them, the main frame 111 and the connecting member 1115 can be integrally formed or fixedly connected. Specifically, viewed from the width direction of the motorcycle 100, the connecting portions 1441 are basically arranged around the outside of the battery housing 144, and the connecting members 1115 are basically arranged around the inside of the main frame 111. Through the above arrangement, the power battery 14 and the main frame 111 can be fixedly connected through the connecting portions 1441 and the connecting members 1115, thereby simplifying the connection relationship between the power battery 14 and the main frame 111, and facilitating the installation of the power battery 14 and the main frame 111, and further beneficial to improving the assembly performance of the two. In addition, a certain gap is left between the power battery 14 and the main frame 111, which can facilitate the arrangement of parts such as wiring harnesses, and further beneficial to improving the space utilization rate of the motorcycle 100.

[0041] As an implementation, the connecting member 1115 extends at least partially towards the power battery 14, the connecting portion 1441 extends at least partially towards the main frame 111, and at least a part of the connecting member 1115 and the connecting portion 1441 are disposed between the main frame 111 and the power battery 14, so that the main frame 111 and the power battery 14 are separated. Specifically, the connecting member 1115 can be configured as a triangular bracket structure. The connecting member 1115 includes at least two first connection points 1115a and second connection points 1115b. The first connection point 1115a is connected to the frame 11, the second connection point 1115b is connected to the connecting portion 1441, and mounting holes are provided on both the first connection point 1115a and the second connection point 1115b. The mounting hole of the first connection point 1115a is connected to the main frame 111 through a fastener, and the mounting hole of the second connection point 1115b is connected to the connecting portion 1441 through a fastener, so as to maintain a certain distance between the main frame 111 and the drive motor 131, which is convenient for the installation and disassembly of the power battery 14. At the same time, the power battery 14 is electrically connected to other electrical devices through a wiring harness. The wiring harness can be arranged between the power battery 14 and the frame 11, which is also beneficial to improving the layout rationality of the motorcycle 100. It should be noted that the number of the first connection points 1115a and the second connection points 1115b can be increased according to actual needs to meet the connection stability between the power battery 14 and the frame 11.

[0042] As an implementation, the projection of the main accommodation space 101 in the longitudinal plane 102 along the width direction of the motorcycle 100 is a space projection, and the projection of the power battery 14 in the longitudinal plane 102 along the width direction of the motorcycle 100 is a battery projection. The battery projection is located within the space projection. Through the above setting, the power battery 14 can be installed into the main accommodation space 101 along the width direction of the motorcycle 100, which is convenient for the assembly of the power battery 14 and the main accommodation space 101, and is also beneficial to improving the assembly performance of the motorcycle 100.

[0043] As an implementation, the volume of the first battery body 142 is larger than that of the second battery body 143.

In addition, hollow portions 1446 are provided on both the first connecting portion 1442a and the second connecting portion 1443a. The hollow portions 1446 are provided between the through holes 1445 and the battery housing 144.

Through the above arrangement, the structures of the connecting portion 1441, the connecting member 1115 and the main frame 111 are compact, which is beneficial to improving the structural compactness of the motorcycle 100. In addition, the power battery 14 and the main frame 111 can be fixedly connected through the connecting portion 1441 and the connecting member 1115, which simplifies the connection relationship between the power battery 14 and the main frame 111, and facilitates the installation of the power battery 14 and the main frame 111, and thus is beneficial to improving the assemblability of the power battery 14 and the main frame 111.

This is conducive to improving the structural compactness of the drive motor 131 and the linkage mechanism 153, and at the same time is conducive to improving the space utilization rate of the motorcycle 100.

[0050] Specifically, a motor mounting hole 1313 is provided on the drive motor 131, and a frame mounting hole 1131 is provided on the motor connecting frame 113.

The connecting rod strengthening part 1142 can be arranged at the connection between the vehicle frame 11 and the connecting rod connecting frame 114, thus further improving the connection strength between the vehicle frame 11 and the connecting rod connecting frame 114.

[0053] As an implementation method, the motor strengthening part 1132 and the connecting rod strengthening part 1142 are fixedly connected or integrally formed. Through the above arrangement, the motor connecting frame 113 and the connecting rod connecting frame 114 are fixedly connected through the motor strengthening part 1132 and the connecting rod strengthening part 1142, which can improve the connection strength between the motor connecting frame 113 and the connecting rod connecting frame 114.

Through the above arrangement, both the first fastener 1131a and the second fastener 1141a can be connected to the locking structure 1143, facilitating the assembly of the drive motor 131 and the connecting rod mechanism 153, thereby being conducive to improving the assembly performance of the motorcycle 100. In this embodiment, the locking structure 1143 can be provided as a structure such as a bolt, facilitating the passing through of the first fastener 1131a and the second fastener 1141a.

[0055] As an implementation, the lower support frame 1114 includes a support pipe 1114b extending in the width direction of the motorcycle 100. Both the motor connecting bracket 113 and the connecting rod connecting bracket 114 are connected to the support pipe 1114b. Specifically, the support pipe 1114b is located at the rear side of the lower support frame 1114, and the support pipe 1114b is located between the drive motor 131 and the connecting rod mechanism 153. Along the front-rear direction of the motorcycle 100, the motor connecting bracket 113 is connected to the rear side of the drive motor 131, and the connecting rod connecting bracket 114 is connected to the front side of the connecting rod mechanism 153. The motor connecting bracket 113 and the connecting rod connecting bracket 114 are located between the drive motor 131 and the connecting rod mechanism 153, enabling both the drive motor 131 and the connecting rod mechanism 153 to be connected to the support pipe 1114b, thereby being conducive to improving the connection strength among the support pipe 1114b, the drive motor 131, and the connecting rod mechanism 153. In addition, the structures of the support pipe 1114b, the drive motor 131, and the connecting rod mechanism 153 are compact, further being conducive to improving the structural compactness of the motorcycle 100.

[0056] Such as Figure 7As shown, in this embodiment, the axis of the motor mounting hole 1313 is set as the first projection point in the longitudinal plane 102 along the width direction of the motorcycle 100. The axis of the frame mounting hole 1131 is set as the second projection point in the longitudinal plane 102 along the width direction of the motorcycle 100. The axis of the support pipe 1114b is set as the third projection point in the longitudinal plane 102 along the width direction of the motorcycle 100. The line connecting the first projection point and the third projection point is the first straight line. The line connecting the second projection point and the third projection point is the second straight line. The included angle α between the first straight line and the second straight line is set to be greater than or equal to 60° and less than or equal to 180°. Specifically, the included angle α between the first straight line and the second straight line is set to be greater than or equal to 90° and less than or equal to 140°. More specifically, the included angle α between the first straight line and the second straight line is set to be 101°. Through the above settings, it is possible to avoid the distance between the motor mounting hole 1313 and the frame mounting hole 1131 being too close due to the included angle α between the first projection point and the second projection point being too small, so as to prevent interference between the drive motor 131 and the link mechanism 153, which is beneficial to improving the assembly of the drive motor 131 and the link mechanism 153. Also, it is possible to avoid the distance between the motor mounting hole 1313 and the frame mounting hole 1131 being too far due to the included angle α between the first projection point and the second projection point being too large, so as to prevent the connection strength between the motor connecting frame 113 and the link connecting frame 114 from being reduced, which is beneficial to improving the connection strength between the motor connecting frame 113 and the link connecting frame 114.

[0057] As an implementation, along the length direction of the motorcycle 100, the motor connecting frame 113 is connected to the rear side of the drive motor 131, and the link connecting frame 114 is connected to the front side of the link mechanism 153. The motor connecting frame 113 and the link connecting frame 114 are located between the drive motor 131 and the link mechanism 153, so that the structure of the drive motor 131 and the link mechanism 153 is more compact, which is beneficial to improving the structural compactness of the motorcycle 100. Among them, when observed from the length direction of the motorcycle 100, the motor connecting frame 113 and the link connecting frame 114 at least partially overlap, so that while the motor connecting frame 113 is arranged close to the link connecting frame 114, it does not affect the layout of the drive motor 131 and the link mechanism 153.

[0058] As Figure 8 and Figure 9As shown, as an implementation, the vehicle frame 11 further includes a motor bracket 115. The main vehicle frame 111 includes a plurality of mounting brackets distributed along the length direction of the motorcycle 100 and a plurality of longitudinal vehicle frames distributed along the height direction of the motorcycle 100. The motor bracket 115 is connected to at least one mounting bracket and at least one longitudinal vehicle frame. It should be noted that the upper support frame 1111 and the lower support frame 1114 both belong to the longitudinal vehicle frames. Similarly, the front mounting bracket 1112 and the rear mounting bracket 1113 both belong to the mounting brackets. Through the above settings, the motor bracket 115 can be selectively connected as needed to meet the requirement that the motor bracket 115 is respectively connected to the main vehicle frame 111 and the drive motor 131. In this embodiment, the motor bracket 115 is connected to the rear mounting bracket 1113 and the lower support frame 1114 as an example for illustration.

[0059] In this embodiment, the motor bracket 115 includes at least two mounting portions 1151 connected to the main vehicle frame 111. The motor bracket 115 further includes a connecting portion 1152 connected to the drive motor 131. The connecting portion 1152 is disposed between any two mounting portions 1151, and at least part of the connecting portion 1152 is disposed in the main accommodation space 101 and connected to the drive motor 131. Specifically, along the left-right direction of the motorcycle 100, at least part of the motor bracket 115 is disposed on the left side and / or the right side of the drive motor 131, and the drive motor 131 can be connected to the main vehicle frame 111 through the motor bracket 115. Through the above settings, it is beneficial to improve the connection stability between the drive motor 131 and the main vehicle frame 111. Among them, viewed from the width direction of the motorcycle 100, the motor bracket 115 at least partially overlaps with the drive motor 131, which is beneficial to improving the structural compactness of the drive motor 131 and the motor bracket 115, and at the same time beneficial to improving the space utilization rate of the motorcycle 100.

[0060] As an implementation, the main vehicle frame 111 includes a rear mounting bracket 1113 extending along the height direction of the motorcycle 100 and a lower support frame 1114 extending along the length direction of the motorcycle 100. A bracket mounting portion 1113b is provided on the rear mounting bracket 1113, and a motor mounting portion 1114a is provided on the lower support frame 1114 (see Figure 3) The mounting part 1151 includes a first mounting part 1151a and a second mounting part 1151b. The first mounting part 1151a is connected to the bracket mounting part 1113b, and the second mounting part 1151b is connected to the motor mounting part 1114a, so that the motor bracket 115 is respectively connected to the lower support frame 1114 and the rear mounting frame 1113. Through the above arrangement, the connection strength between the motor bracket 115 and the main frame 111 can be improved, which is beneficial to improving the connection stability between the drive motor 131 and the frame 11, and further beneficial to improving the structural stability of the motorcycle 100. It should be noted that the drive motor 131 and the motor bracket 1114a are detachably connected by a fastener. Therefore, the second mounting part 1151b and the drive motor 131 can be connected to the motor mounting part 1114a by a fastener, so as to reduce the number of connection points arranged on the motor mounting part 1114a, which is beneficial to improving the assembly performance of the second mounting part 1151b and the drive motor 131. At the same time, the connection strength between the second mounting part 1151b and the drive motor 131 and the motor mounting part 1114a can also be improved, which is beneficial to improving the structural stability of the motorcycle.

[0061] As an implementation manner, the motor bracket 115 includes a first support frame 1153 that extends substantially along the front-rear direction of the motorcycle 100 and a second support frame 1154 that extends substantially along the up-down direction of the motorcycle 100. The first support frame 1153 is fixedly connected to the second support frame 1154. The first mounting part 1151a is arranged on the first support frame 1153, and the second mounting part 1151b is arranged on the second support frame 1154, so that the first support frame 1153 is connected to the rear mounting frame 1113, and the second support frame 1154 is connected to the lower support frame 1114. Specifically, when observed along the width direction of the motorcycle 100, the first support frame 1153 and the second support frame 1154 are substantially arranged at a right angle, which is beneficial to improving the structural stability of the first support frame 1153 and the second support frame 1154, and at the same time is beneficial to improving the structural compactness of the first support frame 1153 and the second support frame 1154, and further beneficial to improving the structural strength and structural compactness of the motor bracket.

[0062] As an implementation manner, the motor bracket 115 further includes a bracket tube 1155 that at least partially extends toward the drive motor 131. The bracket tube 1155 is connected to the drive motor 131, and the bracket tube 1155 extends substantially along the width direction of the motorcycle 100. Specifically, the bracket tube 1155 is connected to a part of the drive motor 131 away from the main frame 111, so that the drive motor 131 can be stably connected to the main frame 111 through the bracket tube 1155. Among them, a circular through hole 1155a is arranged in the bracket tube 1155, and a motor through hole 1314 corresponding to the circular through hole 1155a is arranged on the drive motor 131 (see Figure 5) The fastener passes through the motor through-hole 1314 and the circular through-hole 1155a to fixedly connect the drive motor 131 to the support pipe 1155. Through the above arrangement, the support pipe 1155 can be disassembled and installed from the drive motor 131 and the main frame 111 as needed, which is conducive to improving the assembly efficiency of the motor bracket 115, the drive motor 131, and the main frame 111. At the same time, the support pipe 1155 has high strength, and the fastener can be a bolt with high strength, which is conducive to improving the connection strength between the drive motor 131 and the motor bracket 115, and further conducive to improving the structural stability of the motorcycle 100.

[0063] In this embodiment, the extending direction of the support pipe 1155 is substantially perpendicular to the first support frame 1153 and the second support frame 1154. An electric motor accommodation space 135 is formed around the first support frame 1153, the second support frame 1154, the support pipe 1155, the rear mounting frame 1113, and the lower support frame 1114. At least a part of the drive motor 131 is located in the electric motor accommodation space 135. Through the above arrangement, the drive motor 131 occupies a relatively large electric motor accommodation space 135, making the structure of the drive motor 131 and the motor bracket 115 more compact, which is conducive to improving the structural compactness of the drive motor 131 and the motor bracket 115.

[0064] As an implementation, the motor controller 132 is disposed on the upper side of the drive motor 131 and fixedly connected to the drive motor 131. The body covering 16 includes a motor guard plate 163. The motor guard plate 163 is at least partially disposed on the upper side of the motor bracket 115 and connected to the motor bracket 115. When observed from the width direction of the motorcycle 100, the motor guard plate 163 and the motor controller 132 at least partially overlap, and the motor guard plate 163 and the drive motor 131 at least partially overlap. Through the above arrangement, substances such as flying stones can be prevented from damaging the drive motor 131 and the motor controller 132, so that the motor guard plate 163 can protect both the drive motor 131 and the motor controller 132, which is conducive to improving the service life of the drive motor 131 and the motor controller 132. Specifically, mounting holes 1156 are provided on the upper side of the motor bracket 115, and guard plate through holes 1631 are provided on the motor guard plate 163. Fasteners pass through the mounting holes 1156 and the guard plate through holes 1631 to fixedly connect the motor bracket 115 and the motor guard plate 163. Through the above arrangement, the motor guard plate 163 can be stably connected to the motor bracket 115, which is conducive to improving the structural stability of the motor bracket 115 and the motor guard plate 163. In addition, the motorcycle 100 further includes a power battery 14. The power battery 14 is connected to the main frame 111. The power battery 14 includes a battery opening 141, and the drive motor 131, the motor controller 132, the motor guard plate 163 and the motor bracket 115 are all at least partially located within the battery opening 141. Through the above arrangement, the structures of the drive motor 131, the motor controller 132, the motor guard plate 163, the motor bracket 115 and the power battery 14 are more compact, which is conducive to improving the structural compactness of the motorcycle 100.

[0065] In the present embodiment, the projection of the motor controller 132 on the longitudinal plane 102 in the width direction of the motorcycle 100 is set as the third projection plane, and the total projection of the motor guard plate 163 and the motor bracket 115 on the third projection plane in the width direction of the motorcycle 100 is set as the fourth projection plane. The ratio of the area of the third projection plane to the area of the fourth projection plane is set to be greater than or equal to 1.05 and less than or equal to 1.54. Specifically, the ratio of the area of the third projection plane to the area of the fourth projection plane is set to be greater than or equal to 1.16 and less than or equal to 1.4. More specifically, the ratio of the area of the third projection plane to the area of the fourth projection plane is set to 1.28. Through the above arrangement, it can be avoided that the volume of the motor guard plate 163 is too large due to the too large ratio of the area of the third projection plane to the area of the fourth projection plane, so as to prevent the motor guard plate 163 from occupying a large layout space, which is conducive to improving the space utilization rate of the motorcycle 100; and it can also be avoided that the volume of the motor guard plate 163 is too small due to the too small ratio of the area of the third projection plane to the area of the fourth projection plane, so as to prevent the protection performance of the motor guard plate 163 from being reduced, which is conducive to improving the protection performance of the motor guard plate 163.

[0066] Such asFigure 1 and Figure 10 As shown in Figure 1 and Figure 10 , the motorcycle 100 includes a footrest assembly 21. The footrest assembly 21 is at least partially disposed on the frame 11 and is used to carry the feet of the user. Among them, a first mounting structure 116 is provided on the frame 11. The footrest assembly 21 includes a second mounting structure 211 and a footrest member 212. The footrest member 212 is connected to the first mounting structure 116 through the second mounting structure 211. A plurality of mounting holes 1161 are provided on the first mounting structure 116. The mounting holes 1161 are distributed substantially along the height direction of the motorcycle 100. The second mounting structure 211 at least partially passes through any one of the mounting holes 1161 and is fixedly connected to the mounting hole 1161. Specifically, a contact member 2112 is provided on the second mounting structure 211. The footrest member 212 and the second mounting structure 211 are arranged to be detachably connected, and the contact member 2112 can move in the axial direction of the mounting hole 1161. When the footrest member 212 is connected to the second mounting structure 211, the footrest member 212 is located between the contact member 2112 and the first mounting structure 116 and abuts against the contact member 2112 and the first mounting structure 116. Through the above settings, the second mounting structure 211 is fixedly connected to different mounting holes 1161, so that the second mounting structure 211 can be adjusted in the height direction of the motorcycle 100. The movement of the contact member 2112 in the axial direction of the mounting hole 1161 also enables the footrest member to be adjusted in the length direction of the motorcycle 100, so that the footrest member 212 can be adjusted according to the needs of different drivers, thereby improving the human-machine interaction of the motorcycle 100 and the driving comfort of the motorcycle 100. It should be noted that any one of the mounting holes 1161 can refer to one of the mounting holes 1161 or a pair of the mounting holes 1161. When any one of the mounting holes 1161 refers to a pair of the mounting holes 1161, both ends of the second mounting structure 211 are respectively fixedly connected to two of the mounting holes 1161 in any pair of the mounting holes 1161.

[0067] As Figure 11As shown, in this embodiment, along the width direction of the motorcycle 100, the first mounting structure 116 protrudes away from the motorcycle 100 to form a protruding portion 1162, and a plurality of mounting holes 1161 are provided on the protruding portion 1162, and the plurality of mounting holes 1161 are basically distributed along the height direction of the motorcycle 100. It should be noted that when the mounting holes 1161 are distributed in pairs, the protruding portion 1162 includes a first protruding portion 1162a and a second protruding portion 1162b, the first protruding portion 1162a and the second protruding portion 1162b are basically distributed along the length direction of the motorcycle 100, and the two mounting holes 1161 in any pair of mounting holes 1161 are respectively arranged on the first protruding portion 1162a and the second protruding portion 1162b, and the second mounting structure 211 is at least partially passed through the two mounting holes 1161 and then fixedly connected to the first protruding portion 1162a and the second protruding portion 1162b.

[0068] Specifically, the second mounting structure 211 includes a mounting portion 2111, the mounting portion 2111 is at least partially passed through the mounting hole 1161 and fixedly connected to the mounting hole 1161, the mounting portion 2111 and the footrest 212 are both arranged on the first mounting structure 116, the abutting member 2112 is sleeved on the mounting portion 2111, and when there are at least two abutting members 2112, both of the two abutting members 2112 abut against the protruding portion 1162, and the footrest 212 is located between the two abutting members 2112 and abuts against the abutting members 2112. In the above setting, the mounting portion 2111 can be connected to different mounting holes 1161 to realize the position adjustment of the footrest 212 in the height direction of the motorcycle 100, or the relative position of the footrest 212 and the abutting member 2112 can be changed to realize the position adjustment of the footrest 212 in the length direction of the motorcycle 100, so that the user can adjust the position of the footrest assembly 21 in the height direction and the length direction according to his own needs and usage habits, and further improve the riding comfort of the user and the human-computer interaction of the motorcycle 100.

[0069] It should be noted that the mounting portion 2111 can be provided with a cylindrical shaft or a square shaft. When the mounting portion 2111 is provided as a square shaft, the footrest 212 is fixedly connected to the mounting portion 2111, so that the connection strength of the footrest 212 can be improved; when the mounting portion 2111 is provided as a cylindrical shaft, the footrest 212 and the mounting portion 2111 can be rotatably connected, so that the footrest 212 can be rotatably stored, improving the structural compactness of the motorcycle 100. In the embodiment of the present application, the mounting portion 2111 is provided as a cylindrical shaft.

[0070] As an alternative implementation, the mounting holes 1161 can be provided in three positions in the height direction of the motorcycle 100, so that the footrest member 212 can have three optional position adjustments in the height direction. It can be understood that the number of the mounting holes 1161 provided in the embodiments of the present application is only a preferred implementation. Specifically, the mounting holes 1161 can be provided in a plurality, and at least two mounting holes 1161 can be provided to achieve the position adjustment of the footrest member 212 in the height direction of the motorcycle 100.

[0071] As an implementation, the footrest member 212 further includes an elastic member 213 for resetting the footrest member 212. The elastic member 213 is at least partially disposed on the second mounting structure 211. One end of the elastic member 213 abuts against the first mounting structure 116, and the other end of the elastic member 213 abuts against the footrest member 212. The footrest member 212 includes a reset position and a working position. When the footrest member 212 is in the reset position, the elastic member 213 is in a pre-tightened state. When the footrest member 212 is in the working position, the elastic member 213 deforms to increase the acting force of the elastic member 213 on the footrest member 212, so that the footrest member 212 moves from the working position to the reset position, or so that the footrest member 212 has a tendency to move from the working position to the reset position.

[0072] Specifically, the elastic member 213 can be provided as a torsion spring, and the torsion spring is sleeved on the mounting portion 2111. The first mounting structure 116 is further provided with a first adjustment hole 1163. At least a part of the end of the elastic member 213 away from the footrest member 212 is located in the first adjustment hole 1163 and abuts against the first adjustment hole 1163, and the other end of the elastic member 213 abuts against the footrest member 212, so that the footrest member 212 can move from the working position to the reset position under the elastic deformation of the elastic member 213. More specifically, a plurality of first adjustment holes 1163 are provided. After the footrest member 212 is adjusted in position, the elastic member 213 can also be adjusted accordingly, so that the elastic member 213 can work normally even when its position changes. Through the above settings, when the user does not step on the footrest portion, the footrest member 212 can be automatically retracted through the elastic member 213, thereby improving the structural compactness of the footrest assembly 21.

[0073] In this embodiment, the footrest assembly 21 further includes an adjusting member 214. One end of the adjusting member 214 is fixedly connected to the first mounting structure 116 through a fastener, and the other end of the adjusting member 214 and the first mounting structure 116 are connected by a positioning pin 2141. Specifically, a second adjusting hole 2142 is further provided on the adjusting member 214. The mounting hole 1161 includes at least one first mounting hole 1161 and a second mounting hole 1161 located below the first mounting hole 1161. When the second mounting structure 211 is located in the first mounting hole 1161, at least a part of the end of the elastic member 213 away from the footrest 212 is disposed in the first adjusting hole 1163. When the second mounting structure 211 is located in the second mounting hole 1161, at least a part of the end of the elastic member 213 away from the footrest 212 is disposed in the second adjusting hole 2142. Multiple second adjusting holes 2142 may also be provided to realize the position adjustment of the footrest 212 in the longitudinal direction of the motorcycle 100. Through the above settings, when the footrest 212 is adjusted in the longitudinal direction of the motorcycle 100, the first adjusting hole 1163 will not interfere with the elastic member 213; when the footrest 212 is adjusted in the height direction of the motorcycle 100, the adjusting member 214 enables the elastic member 213 to be in a normal working state, so that the footrest 212 can be retracted in different positions, improving the working stability of the footrest assembly 21.

[0074] As Figure 12As shown, in this embodiment, the axis of the mounting hole 1161 is defined as a preset straight line 201, the abutment member 2112 is basically distributed along the preset straight line 201, and a reference plane 103 perpendicular to the height direction of the motorcycle 100 is defined, and the acute angle β formed by the preset straight line 201 and the reference plane 103 is greater than 0° and less than 90°. Specifically, the acute angle β formed by the preset straight line 201 and the reference plane 103 can also be greater than or equal to 20° and less than or equal to 60°. More specifically, the acute angle β formed by the preset straight line 201 and the reference plane is 30°. Through the above arrangement, the pedal member 212 can adjust the position of the pedal member 212 in the length direction of the motorcycle 100 by changing the positional relationship with the abutment member 2112, and at the same time, the position of the pedal member 212 in the height direction of the motorcycle 100 can be adjusted to a certain extent, thereby improving the adjustment performance of the pedal member 212, and further improving the human-machine interaction of the motorcycle 100. It should be noted that if the angle β between the preset straight line 201 and the reference plane 103 is 0°, that is, the direction of the preset straight line 201 is the length direction of the motorcycle 100, the footrest member 212 can only achieve position adjustment in the length direction of the motorcycle 100 through the abutment member 2112; if the angle β between the preset straight line 201 and the reference plane 103 is 90°, the footrest member 212 can achieve adjustment in the height direction of the footrest member 212 by changing the positional relationship with the abutment member 2112, and the mounting portion 2111 can achieve adjustment in the length direction of the footrest member 212 through different mounting holes 1161.

[0075] As an implementation method, a reference plane 103 perpendicular to the height direction of the motorcycle 100 is defined, the lowermost end of the walking system 12 is arranged on the reference plane 103, and the minimum distance H1 between the footrest 212 and the reference plane 103 is greater than or equal to 340 mm and less than or equal to 480 mm. Specifically, the minimum distance H1 between the footrest 212 and the reference plane 103 is greater than or equal to 360 mm and less than or equal to 440 mm. In the present application, the minimum distance H1 between the footrest 212 and the reference plane 103 is 400 mm. Through the above-mentioned configuration, it is possible to prevent the height of the footrest 212 from being too low, thereby preventing the footrest 212 from being damaged due to collision caused by splashing sand and gravel during the driving of the motorcycle 100; it is also possible to prevent the height of the footrest 212 from being too low and causing injuries to the user's feet during the driving of the motorcycle 100, thereby improving the safety of the motorcycle 100; it is also possible to prevent the height of the footrest 212 from being too high and failing to meet the user's requirements for the height of the footrest 212, thereby improving the driving experience and human-computer interactivity of the motorcycle 100.
