[0035] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the scope of protection of the claims attached to this application.

[0036] like Figures 1 to 3 As shown, an electric two-wheeled vehicle 100 includes a frame 11, a suspension assembly 12, a running system 13, a body covering 14, a seat barrel assembly 15, a lighting system 16 and a battery system (not shown). The frame 11 is used to form an overall structure and support the battery system and the body covering 14. The running system 13 is connected to the frame 11 through the suspension assembly 12 to drive the electric two-wheeled vehicle 100 to travel. The seat barrel assembly 15 is at least partially connected to the frame 11 and can be used for the driver to sit. The battery system is at least partially arranged in the space formed by the frame 11, and the body covering 14 covers the frame 11 to isolate other components in the frame 11 from the outside world, and at the same time protect the equipment and structure inside the vehicle. The lighting system 16 provides lighting, turn indication signals and warning signals for the electric two-wheeled vehicle 100. The battery system provides electrical energy to the electric two-wheeled vehicle 100 for driving the electric two-wheeled vehicle 100. In order to clearly illustrate the technical solution of the present application, it is also defined as follows Figure 1 The front, rear, top, bottom, left and right sides shown in the figure indicate that the front-to-back direction is the length direction of the electric two-wheeled vehicle 100, the left-to-right direction is the width direction of the electric two-wheeled vehicle 100, and the up-down direction is the height direction of the electric two-wheeled vehicle 100.

[0037] like Figures 1 to 5As shown, the frame 11 includes a main frame 111 and a subframe 112 for forming the overall structure of the electric two-wheeled vehicle 100. The subframe 112 is at least partially arranged behind the main frame 111 and is configured to be detachably connected to the main frame 111. The main frame 111 includes a support vertical tube 1111, a left tube 1112, and a right tube 1113. The support vertical tube 1111 is generally distributed along the height direction of the frame 11, and the left tube 1112 and the right tube 1113 are both configured to extend generally along the length direction of the frame 11. The left tube 1112 and the right tube 1113 are both fixedly connected to the support vertical tube 1111. A plane perpendicular to the width direction of the electric two-wheeled vehicle 100 and passing through the center of the width of the electric two-wheeled vehicle 100 is defined as the longitudinal center plane 101 of the electric two-wheeled vehicle 100. The left tube 1113 and the right tube 1113 are both at least partially recessed toward the longitudinal center plane. The left tube 1112 and the right tube 1113 are basically symmetrically arranged along the longitudinal center plane. Since the main frame 111 of the electric two-wheeled vehicle 100 is basically symmetrically arranged about the longitudinal center plane 101, only one side of the symmetrical structure is described below.

[0038] like Figures 1 to 6As shown, the left tube 1112 is recessed into the longitudinal plane to form a clearance space 102. The vehicle frame 11 also includes a foot assembly 113, at least partially located in the clearance space 102. The left tube 1112 includes a left upper tube 1112a and a left lower tube 1112b, while the right tube 1113 includes a right upper tube 1113a and a right lower tube 1113b. A receiving gap is formed between the left upper tube 1112a and the left lower tube 1112b. The left upper tube 1112a and the left lower tube 1112b can be configured as circular tubes, rectangular tubes, or oval tubes. The vehicle frame 11 may also include a foot assembly 113. The main frame 111 also includes a reinforcing plate 1114. A plurality of reinforcing plates 1114 are disposed between the upper left tube 1112a and the lower left tube 1112b. These plates 1114 are used to connect the upper left tube 1112a and the lower left tube 1112b. These plates 1114 extend substantially along the height of the frame 11 and serve to connect the upper left tube 1112a and the lower left tube 1112b, thereby enhancing the strength of the upper left tube 1112a and the lower left tube 1112b. With this arrangement, both the left tube 1112 and the right tube 1113 are configured as double-layered tubes, enhancing the overall strength of the frame 11 while also providing mounting locations for the foot assembly 113. This makes the frame 11 more compact, more space-efficient, and more lightweight. Furthermore, mounting holes are provided on the reinforcing plate 1114. This arrangement not only enhances the strength of the double-layer side tube formed by the upper left side tube 1112a and the lower left side tube 1112b, but also provides a mounting location for the wiring harness of the electric two-wheeled vehicle 100. The left side tube 1112 and the right side tube 1113 are respectively provided at opposite ends of the main frame 111 in the width direction. As will be understood, the structure and connection method of the left side tube 1112 and the right side tube 1113 are substantially identical. The following description will focus solely on the connection method of the left side tube 1112.

[0039] As an optional embodiment, the front end of the upper left side tube 1112a is connected to the vertical support tube 1111, and the front end of the lower left side tube 1112b is connected to the vertical support tube 1111. The upper left side tube 1112a includes an upper left straight section 1112c extending substantially along the front-to-back direction of the frame 11. The upper left side tube 1112a also includes an upper left inwardly recessed section 1112d disposed behind the upper left straight section 1112c and recessed toward the longitudinal center plane of the frame 11. The upper left side tube 1112a also includes an upper left extended section 1112e disposed behind the upper inwardly recessed section and extending in a rearward and upward direction. The lower left side tube 1112b includes a lower left straight section 1112f extending substantially along the front-to-back direction of the frame 11. The lower left side tube 1112b also includes a lower left inwardly recessed section 1112g disposed behind the upper straight section and recessed toward the longitudinal center plane of the electric two-wheeled vehicle.

[0040] In one embodiment, the front end of the upper right side tube 1113a is connected to the support vertical tube 1111. The upper right side tube 1113a includes an upper right straight section 1113c extending substantially along the front-to-back direction of the vehicle frame 11. The upper right side tube 1113a also includes an upper right indented section 1113d disposed behind the upper right straight section 1113c and recessed toward the longitudinal center plane of the vehicle frame 11. Along the height direction of the vehicle frame 11, the maximum distance between the upper left straight section 1112c and the upper right straight section 1113c is defined as W1, and the maximum distance between the upper left indented section 1112d and the upper right indented section 1113d is defined as W2. Specifically, the ratio of W1 to W2 is set within a predetermined range. More specifically, the ratio of W1 to W2 ranges from 1.15 to 1.25. As an optional embodiment, the ratio of W1 to W2 ranges from 1.17 to 1.23. As an optional embodiment, the ratio of W1 to W2 ranges from 1.19 to 1.21. Under this setting, the ratio of W1 to W2 is in a suitable range, that is, it can provide a suitable width for the driver to ride, and can provide as much installation space as possible for the pedals for the rear passengers to rest their feet. It is understandable that when the ratio of W1 to W2 is set to be greater than this range, the distance along the width direction of the frame 11 is too large to be convenient for the driver to ride, and it is not conducive to lightweighting; when the ratio of W1 to W2 is set to be less than this range, the rear passengers cannot place their feet comfortably. It is understandable that the ratio of W1 to W2 can be 1.18, 1.2, 1.22, etc.

[0041] As an optional embodiment, the main frame 111 further includes a mounting plate 1115, and the suspension assembly 12 includes a rear fork 121. The rear fork 121 is connected to the main frame 111 via the mounting plate 1115. When viewed along the height direction of the frame 11, the mounting plate 1115 is at least partially located below the extension section. As an optional embodiment, one mounting plate 1115 is provided, and the mounting plate 1115 is disposed between the upper left side tube 1112a and the lower left side tube 1112b, or the mounting plate 1115 is disposed between the upper right side tube 1113a and the lower right side tube 1113b. As another optional embodiment, two mounting plates 1115 are provided, one mounting plate 1115 is disposed between the upper left side tube 1112a and the lower left side tube 1112b, and the other mounting plate is disposed between the upper right side tube 1113a and the lower right side tube 1113b. The two mounting plates 1115 are respectively arranged at both ends of the width direction of the main frame 111. It can be understood that the structures and connection methods of the two mounting plates 1115 are basically the same. The following only describes the structure of one of the mounting plates 1115 and the connection method.

[0042] It is understood that the frame 11 can also be provided with a foot assembly 113, and the foot assembly 113 can be provided with two foot pedals 1131 respectively arranged at both ends of the width direction of the main frame 111. The foot assembly 113 is detachably connected to the main frame 111. As an optional embodiment, the foot assembly 113 includes a foot pedal 1131, and the foot pedal 1131 is configured as a "7"-shaped metal plate. The upper end surface of the foot pedal 1131 is substantially in the same horizontal plane as the upper end of the left upper side tube 1112a. The side of the foot pedal 1131 is detachably connected to the main frame 111. Specifically, the side of the foot pedal 1131 is detachably provided on the upper inward segment and / or the lower inner line segment. As another optional embodiment, the reinforcement plate 1114 is connected between the upper inward segment and / or the lower inward segment, and the side of the foot pedal 1131 is detachably provided on the reinforcement plate 1114. As another optional embodiment, the side of the footrest 1131 is detachably provided on the reinforcement plate 1114 and the mounting plate 1115 .

[0043] like Figures 1 to 6 As shown, the vehicle body cover 14 includes a cover body 141 and a footrest guard 142, which is detachably connected to the cover body 141. The footrest guard 142 at least partially covers the footrest 1131. The footrest guard 142 includes a pedal panel 1421 and a side panel 1422, which are detachably connected along the height of the vehicle frame 11. When viewed along the height of the vehicle frame 11, the pedal panel 1421 and the footrest 1131 substantially overlap. The pedal panel 1421 abuts the upper end surface of the footrest 1131, ensuring that the pedal panel 1421 is evenly stressed when a rear passenger places their foot. Furthermore, after installation, the footrest guard 142 wraps around the footrest 1131, obscuring the connection between the footrest 1131 and the main frame 111, resulting in a more aesthetically pleasing appearance. Under the above configuration, if the electric two-wheeled vehicle 100 does not need to increase transportation requirements, the footrest 1131 and the footrest guard 142 can be removed. At this time, the front driver's legs naturally hang down and are placed on the ground. The frame at the position where his legs are located is narrow, which is convenient for the driver to perform parking operations and provides higher human comfort. When the electric two-wheeled vehicle 100 needs to increase transportation requirements, the footrest 1131 can be installed along the width direction of the frame at the outer edge of the recessed section, and the footrest guard 142 can be installed on the footrest 1131 to provide space for the rear passenger to place their feet without changing the main frame 111 and the cover body 141. This makes the main frame 111 and the cover body 141 more versatile, that is, the cost required to increase transportation requirements is lower.

[0044] like Figures 1 to 9As shown, the subframe 112 is at least partially disposed behind the main frame 111 and is detachably connected to the main frame 111. The main frame 111 also includes a connecting cross tube 1116, which is disposed between the left upper side tube 1112a and the right upper side tube 1113a. The connecting cross tube 1116 extends substantially along the width of the frame 11. The subframe 112 is at least partially located behind the connecting cross tube 1116. As an alternative embodiment, the subframe 112 is detachably connected to the connecting cross tube 1116. As another alternative embodiment, the subframe 112 is detachably connected to the connecting cross tube 1116, the left upper side tube 1112, and the right upper side tube 113.

[0045] As an optional embodiment, the electric two-wheeled vehicle 100 includes a first assembly state, a second assembly state, a third assembly state, and a fourth assembly state. The subframe 112 includes at least one of a first extension frame 1121, a second extension frame 1122, and a third extension frame 1123. The first extension frame 1121 is a seat mounting frame, through which an additional seat can be mounted to the main frame 111. The second extension frame 1122 is a frame extension frame that can extend the length of the electric two-wheeled vehicle 100. The third extension frame 1123 is a rear armrest frame. The cover body 141 includes at least one of a long tail assembly 1411 and a short tail assembly 1412. When the electric two-wheeled vehicle 100 is in a first assembly state, the first extension frame 1121 is installed and the short tail assembly 1412 is configured. When the electric two-wheeled vehicle 100 is in a second assembly state, the second extension frame 1122 is assembled and the long tail assembly 1411 is configured. When the electric two-wheeled vehicle 100 is in the first assembly state, the subframe 112 is not installed. In the third assembly state, the third extension frame 1123 is assembled and the short tail assembly 1412 is configured. With this configuration, the electric two-wheeled vehicle 100 includes multiple transport states, and the subframe 112 includes multiple shapes and sizes. When the electric two-wheeled vehicle 100 needs to change its transport state according to actual needs, it only needs to assemble a different subframe 112 and cover body 141, without changing the main frame 111, thereby improving the versatility of the frame 11.

[0046] As an optional embodiment, the short tail assembly 1412 is arranged below the seat bucket assembly 15, the short tail assembly 1412 is fixedly connected to the main frame 111, the seat cushion 151 includes at least one of a long seat cushion (not shown) and a short seat cushion (not shown), and the short tail assembly 1412 is rotatably connected to the short seat cushion. Observed along the height direction of the frame 11, the short tail assembly 1412 basically overlaps with the seat bucket assembly 15. When installing the short tail assembly 1412, you can choose to install the first extension frame 1121 or the third extension frame 1123. The first extension frame 1121 is basically symmetrical about the longitudinal plane. The first extension frame 1121 is a seat mounting frame, and the first extension frame 1121 is used to add a seat, and the seat can be arranged above the first extension frame 1121. The projection of the first extension frame 1121 on the longitudinal plane along the width direction of the frame 11 is a triangle. The first extension frame 1121 is set to a metal material. In this configuration, the first extension frame 1121 forms a stable triangular structure, and the first extension frame 1121 has a heavier load.

[0047] As another optional embodiment, the long tail assembly 1411 is arranged below the seat barrel assembly 15, and the long tail assembly 1411 is at least partially arranged on the second extension frame 1122, and the long tail assembly 1411 is rotatably connected to the long seat cushion. The second extension frame 1122 is used to cooperate with the main frame 111 to extend the length of the seat barrel assembly 15, thereby extending the length of the electric two-wheeled vehicle 100 and increasing the carrying capacity of the electric two-wheeled vehicle 100. The long tail assembly 1411 is rotatably connected to the long seat cushion. At this time, the size of the seat cushion 151 of the long tail assembly 1411 at least partially overlaps with the walking system 13. It can be understood that the second extension frame 1122 and the long tail assembly 1411 are detachably installed, and during assembly, it can be decided whether to assemble the second extension frame 1122 and the long tail assembly 1411 according to transportation requirements.

[0048] like Figure 2 、 Figure 10 and Figure 11 As shown, as an implementation, the suspension assembly 12 includes a rear fork 121, through which the rear wheel 132 is connected to the frame 11. Furthermore, one end of the rear fork 121 is rotatably connected to a mounting plate 1115, and the other end of the rear fork 121 is disposed on a rear wheel axle 1321. The main frame 111 also includes a support cross tube 1117, which extends along the width of the frame and is disposed between the left lower side tube 1112b and the right lower side tube 1113b. The support cross tube 1117 can reinforce the strength of the main frame 111. The frame 11 also includes a center brace assembly 114, which is disposed on the support cross tube 1117 and is located below the rear fork 121. When viewed along the height of the frame, the center brace assembly 114 at least partially overlaps with the rear fork 121.

[0049] Specifically, the center support assembly 114 is rotatably connected to the support cross tube 1117. The center support assembly 114 rotates around the extension direction of the support cross tube 1117. The center support assembly 114 includes a first position in which it can be stored and a second position in which it can support the electric two-wheeled vehicle 100. The center support assembly 114 can be switched between the first position and the second position under the operation of the driver to meet the driving and parking requirements of the electric two-wheeled vehicle 100. The support cross tube 1117 also includes an extension portion 1117a, and the center support assembly 114 is arranged on the extension portion 1117a. Under this arrangement, there is no need to add new connecting pipes. By adding the extension portion 1117a to adapt to the position of the center support assembly 114, the vehicle frame can be made lighter while meeting the human-machine requirements of the vehicle.

[0050] like Figure 2 、 Figure 7 As shown in FIG. 1 , as an implementation, the center support assembly 114 includes a center support body 1141, an elastic member 1142, and a buffer member 1143. One end of the elastic member 1142 is disposed on the center support body 1141, and the other end of the elastic member 1142 is disposed on the support cross tube 1117. The elastic member 1142 provides a preload force for the center support body 1141 to approach the support cross tube 1117, thereby allowing the center support assembly 114 to stably remain in the first position or the second position. The center support body 1141 includes a receiving portion 1141a located between the rear fork 121 and the center support body 1141. A buffer 1143 is at least partially disposed in the receiving portion 1141a. The buffer 1143 can be configured as a roller and is made of rubber. The rear fork 121 includes a fork body 1211 and an anti-collision plate 1212. When the center support assembly 114 is in the first position, the buffer 1143 abuts against the anti-collision plate 1212. The anti-collision plate 1212 is fixedly connected to the fork body 1211 and is located below the fork body 1211. When the center support assembly 114 rotates from the second position to the first position, due to the inertia of rotation and the tightening force of the elastic member 1142, the elastic member 1142 first touches the flat fork anti-collision plate 1212, and the elastic member 1142 absorbs the impact force, thereby preventing the center support assembly 114 from damaging the rear flat fork 121, reducing the interference between the center support assembly 114 and the rear flat fork 121, and improving the service life of the rear flat fork 121 and the center support assembly 114.

[0051] like Figures 1 to 15As shown, the seat bucket assembly 15 includes a seat cushion 151 and a first seat bucket body 152. The first seat bucket body 152 is positioned below the seat cushion 151.
