[0036] In order to make the technical scheme of the present application better understood by the persons skilled in the art, the technical scheme in the specific implementation mode of the present application will be described clearly and completely below in conjunction with the drawings in the implementation mode of the present application. It should be understood that, for the ordinary technicians in the field, the above description can be improved or changed, and all these improvements and changes should belong to the protection scope of the claims attached to the present application.

[0037] like Figure 1 , Figure 2 As shown, the present application provides an electric two-wheeled vehicle 100, which includes a frame 11, a body cover 12, a running assembly 13, a suspension assembly 14, a seat assembly 15 and a power assembly 16. The frame 11 is used to form the overall structure of the electric two-wheeled vehicle 100 and support the body cover 12. The body cover 12 covers the frame 11 and is used to isolate other components in the frame 11 from the outside world, and is also used to protect the equipment and structure inside the vehicle. The running assembly 13 is connected to the frame 11 through the suspension assembly 14. The seat assembly 15 is at least partially connected to the frame 11 and can be sat on by the driver. The power assembly 16 is at least partially arranged in the space formed by the frame 11. The power assembly 16 provides power for the electric two-wheeled vehicle 100 to drive the electric two-wheeled vehicle 100. It should be noted that the electric two-wheeled vehicle 100 includes an electric bicycle and an electric motorcycle. 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, 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.

[0038] like Figures 2 to 6As shown, the frame 11 includes a main frame 111 and a sub-frame 112 for forming the overall structure of the electric two-wheeled vehicle 100, and the sub-frame 112 is at least partially arranged at the rear of the main frame 111 and is arranged to be detachably connected to the main frame 111. The main frame 111 includes a head tube 1111, a left tube 1112 and a right tube 1113, and the left tube 1112 and the right tube 1113 are both arranged to extend substantially along the length direction of the electric two-wheeled vehicle 100. The left tube 1112 and the right tube 1113 are both fixedly connected to the head 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 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, for the symmetrical structure, only one side is described below.

[0039] like Figures 2 to 5As shown, the frame 11 also includes a pedal assembly 113, which is distributed along the width direction of the electric two-wheeled vehicle 100, and the pedal assembly 113 is arranged between the left tube 1112 and the right tube 1113. The pedal assembly 113 includes a center beam 1131 and a side beam 1132, the center beam 1131 basically extends along the width direction of the electric two-wheeled vehicle 100, and the center beam 1131 and the side beam 1132 are arranged as substantially coaxial cylinders. There are two side beams 1132, and the two side beams 1132 are respectively arranged at both ends of the center beam 1131. The center beam 1131 includes a main body 1131a, and the center beam 1131 also includes a first connecting portion 1131b and a second connecting portion 1131c arranged opposite to each other along the extending direction of the main body 1131a, and the two side beams 1132 are detachably connected to the first connecting portion 1131b and the second connecting portion 1131c, respectively. The pedal assembly 113 further includes a pedal 1133, which is disposed at one end of the side beam 1132 away from the middle beam 1131 and can rotate synchronously with the side beam 1132. The walking assembly 13 includes a front wheel 131 and a rear wheel 132. The pedal assembly 113 further includes an extension piece 1134 and a sprocket 1135, which is disposed on the side beam 1132 or is transmission-connected to the side beam 1132. The driver drives the side beam 1132 to rotate by stepping on the pedal 1133, and further rotates the sprocket 1135, and the sprocket 1135 transmits power to the front wheel 131 or the rear wheel 132 through a transmission member such as a chain or a belt. The extension piece 1134 is sleeved on the first connecting portion 1131b and / or the second connecting portion 1131c, and is located between the main body 1131a and the side beam 1132, and is used to change the positional relationship of the sprocket 1135 on the pedal assembly 113, or adjust the length of the pedal assembly 113 as a whole along the width direction of the electric two-wheeled vehicle 100. The extension piece 1134 can be set to one or more, and the extension piece 1134 can be set on one side or both sides of the main body 1131a. By changing the number of extension pieces 1134, the width of the extension piece 1134 and / or the position of the extension piece 1134, the length of the pedal assembly 113 along the width direction of the electric two-wheeled vehicle 100 and the position of the sprocket 1135 can be adjusted. The extension piece 1134 can be installed when it is needed, which meets the lightweight of the frame 11. While reducing the cost, it can adapt to frames 11 of different widths to better meet the human-machine comfort.

[0040] As an optional embodiment, the outer peripheral surface of the first connecting portion 1131b is provided with threads, and the inner wall of the side beam 1132 is provided with threads matching the first connecting portion 1131b. The first connecting portion 1131b and the side beam 1132 can be connected by threads. The inner diameter of the extension piece 1134 is greater than or equal to the outer diameter of the first connecting portion 1131b, the inner diameter of the extension piece 1134 is smaller than the outer diameter of the main body 1131a, and the inner diameter of the extension piece 1134 is smaller than the outer diameter of the side beam 1132. Under this setting, the extension piece 1134 can be sleeved outside the first connecting portion 1131b, and the two ends of the extension piece 1134 can respectively abut the main body 1131a and the side beam 1132, and be limited between the main body 1131a and the side beam 1132. When the extension piece 1134 needs to be installed, thread glue can be applied to the outer periphery of the first connecting portion 1131b and the second connecting portion 1131c. Through the above arrangement, the integrity of the extension piece 1134 with the center beam 1131 and the side beam 1132 can be better enhanced.

[0041] As an optional implementation, the inner wall of the first connection portion 1131b is provided with threads, and the outer peripheral surface of the side beam 1132 is provided with threads matching the first connection portion 1131b. The first connection portion 1131b and the side beam 1132 can be connected by threads.

[0042] As an optional implementation, since the transmission between the pedal 1133 and the front wheel 131 or the rear wheel 132 utilizes the ratchet principle, when the pedal 1133 is stepped forward, the side beam 1132 rotates forward accordingly, and the front wheel 131 and / or the rear wheel 132 can rotate accordingly, while when the pedal 1133 is stepped on in the opposite direction, the rear wheel 132 will not rotate accordingly. Therefore, the tightening direction of the thread between the side beam 1132 and the middle beam 1131 is the first rotation direction, and when the user steps on the pedal 1133 and rotates the pedal 1133 along the first rotation direction, the electric two-wheeled vehicle 100 moves forward. When the pedal 1133 is stepped on forward, the tightening of the thread can prevent slipping. The second rotation direction is opposite to the first rotation direction. When the pedal 1133 rotates in the second rotation direction, the chain will not drive the front wheel 131 or the rear wheel 132 to rotate. When the pedal 1133 is touched by mistake, the thread glue between the side beam 1132 and the middle beam 1131 increases the pulling force and friction force, and the side beam 1132 will not slip off when a sufficiently large torque cannot be provided. After the extension piece 1134 is added to the side beam 1132, only the characteristics of the thread itself and the thread glue can prevent slipping, thereby meeting the strength of the entire pedal assembly 113.

[0043] like Figure 2 , Figure 6 , Fig.10As shown, the left tube 1112 includes an upper left tube 1112a and a lower left tube 1112b, and the right tube 1113 includes an upper right tube 1113a and a lower right tube 1113b. An accommodating gap (not shown) is formed between the upper left tube 1112a and the lower left tube 1112b, and an accommodating gap is formed between the upper right tube 1113a and the lower right tube 1113b, and the pedal assembly 113 is arranged in the accommodating gap. The upper left tube 1112a and the lower left tube 1112b can be set to any one of a circular tube, a rectangular tube or an elliptical tube. Under this setting, the left tube 1112 and the right tube 1113 are both set to double-layer tubes, which not only enhances the overall strength of the frame 11, but also provides a mounting position for the pedal assembly 113, so that the frame 11 is more compact, has a higher space utilization rate, and is more lightweight. The left tube 1112 and the right tube 1113 are respectively arranged at the two ends of the width direction of the main frame 111. It can be understood that the structure and connection method of the left tube 1112 and the right tube 1113 are basically the same. The following only describes the structure of the connection method of the left tube 1112.

[0044] As an optional embodiment, the left lower side tube 1112b includes a straight section 1112c extending substantially in the front-rear direction, the left lower side tube 1112b also includes an extension section 1112d arranged at the rear and extending substantially rearward and upward, the rear end of the left upper side tube 1112a is connected to the front end of the left upper side tube 1112a and the front end of the left lower side tube 1112b is connected to the front end of the vehicle head tube 1111. A plurality of reinforcing plates 1117 are also provided between the upper left tube 1112a and the lower left tube 1112b. The reinforcing plates 1117 are used to connect between the upper left tube 1112a and the lower left tube 1112b. The reinforcing plates 1117 extend substantially along the height direction of the electric two-wheeled vehicle 100 and are used to connect the upper left tube 1112a and the lower left tube 1112b, and simultaneously enhance the strength of the upper left tube 1112a and the lower left tube 1112b. In addition, mounting holes are also provided on the reinforcing plates 1117. By such a configuration, the strength of the double-layer tube formed by the upper left tube 1112a and the lower left tube 1112b is enhanced, and an installation position is provided for the wiring harness on the electric two-wheeled vehicle 100.

[0045] As an optional embodiment, the power assembly 16 includes a battery 161, and the frame 11 also includes a front battery mounting plate 114. The front battery mounting plate 114 is distributed along the width direction of the electric two-wheeled vehicle 100 and is basically symmetrically arranged about the longitudinal center plane 101. The front battery mounting plate 114 is at least partially arranged between the left tube 1112 and the right tube 1113, and the battery 161 can be arranged on the front battery mounting plate 114. Through the above arrangement, the strength of the frame 11 is guaranteed, and the installation space requirements of the front battery mounting plate 114 and the pedal assembly 113 are met at the same time.

[0046] In this setting, the power assembly 16 is connected to the main frame 111 through the front battery mounting plate 114 and is located between the left tube 1112 and the right tube 1113, which ensures the comfort of the driver's legs when driving the vehicle, and at the same time provides more power sources for the electric two-wheeled vehicle 100 to improve the endurance. As an optional embodiment, the frame 11 is also provided with a rear battery mounting plate 115, and the rear battery mounting plate 115 is connected to both ends of the width direction of the main frame 111. The power assembly 16 can also be arranged above the rear battery mounting plate 115. The rear battery mounting plate 115 itself forms an arch bridge shape. In this setting, the rear battery mounting plate 115 is a relatively stable structure, thereby providing sufficient support strength for the power assembly 16, without the need for other reinforcement structures, and can achieve lightweight.

[0047] As an optional embodiment, the upper left tube 1112a further includes a recessed portion 1112e close to the longitudinal center plane, the recessed portion 1112e is arranged at the end of the upper left tube 1112a, the recessed portion 1112e is bent upward along the height direction of the electric two-wheeled vehicle 100, and the recessed portion 1112e is recessed toward the longitudinal center plane along the width direction of the electric two-wheeled vehicle 100, thereby saving space below and to the left of the recessed portion, and facilitating the installation of the pedal assembly 113. Furthermore, the pedal 1133 will not interfere with the upper left tube 1112a. There is no need to set other parts of the upper left tube 1112a upward, thereby making the space utilization rate of the electric two-wheeled vehicle 100 higher.

[0048] like Figures 6 to 8 As shown, the frame 11 further includes a connection structure 116, which is used to assemble the sub-frame 112 and / or the suspension assembly 14 to the main frame 111. The connection structure 116 can be provided in two, and the two connection structures 116 are respectively provided at the rear ends of the left tube 1112 and the right tube 1113, and the two connection structures 116 are substantially symmetrical about the longitudinal center plane 101. More specifically, the connection structure 116 is provided at the rear end, and the sub-frame 112 is one of a short tail bracket 1121 and a long tail bracket 1122, and the short tail bracket 1121 or the long tail bracket 1122 can be selectively installed on the main frame 111 through the connection structure 116 according to actual use. The two connection structures 116 are respectively provided 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 connection structures 116 are substantially the same, and only one of the connection structures 116 is described below.

[0049] As an optional embodiment, the connection structure 116 includes an inner connecting plate 1161, an outer connecting plate 1162, and a connecting column 1163. The inner connecting plate 1161 and the outer connecting plate 1162 are arranged opposite to each other along the width direction of the electric two-wheeled vehicle 100. A sandwich space (not shown) is formed between the inner connecting plate 1161 and the outer connecting plate 1162. The connecting column 1163 is located in the sandwich space and is used to connect the inner connecting plate 1161 and the outer connecting plate 1162. The inner connecting plate 1161 is arranged close to the longitudinal center plane 101, and the outer connecting plate 1162 is arranged away from the longitudinal center plane 101. The left tube 1112 is at least partially located in the sandwich space, and the subframe 112 and / or the suspension assembly 14 are at least partially located in the sandwich space. Under this arrangement, the suspension assembly 14 and the main frame 111 are connected through the relative inner connecting plate 1161 and the outer connecting plate 1162, and the connection is more stable.

[0050] As an optional embodiment, the inner connecting plate 1161 is provided with an inner connecting portion 1161a, the outer connecting plate 1162 is provided with an outer connecting portion 1162a, and the sub-frame 112 is one of the short-tail bracket 1121 and the long-tail bracket 1122. As an optional embodiment, when the sub-frame 112 to be installed is the short-tail bracket 1121, the sub-frame 112 can be connected to the main frame 111 through the inner connecting portion 1161a; when the sub-frame 112 to be installed is the long-tail bracket 1122, the sub-frame 112 can be connected to the main frame 111 through the outer connecting portion 1162a. The inner connecting portion 1161a and the outer connecting portion 1162a can be set as mounting holes. Under this setting, the connection structure 116 integrates the connection points of the subframe 112 and the suspension assembly 14, and the connection structure 116 can be equipped with both the short tail bracket 1121 and the long tail bracket 1122 without adding or modifying the connection structure 116, thereby improving the versatility and practicality of the connection structure 116 and reducing costs.

[0051] As an optional embodiment, the short tail bracket 1121 includes a first matching portion (not shown), the first matching portion is set as a mounting hole, and the first matching portion is connected to the inner connecting portion 1161a by bolts and mounting holes. The long tail bracket 1122 includes a second matching portion (not shown), the second matching portion is set as a mounting hole, and the second matching portion is connected to the outer connecting portion 1162a by bolts and mounting holes. The short tail bracket 1121 is connected to the connecting structure 116 by bolts and mounting holes. The short tail bracket 1121 is narrower than the long tail bracket 1122, and the short tail bracket 1121 is at least arranged in the middle of two opposite ones. The long tail bracket 1122 is at least partially arranged on the outside of the two connecting structures 116. Under this setting, the short tail bracket 1121 is narrower than the long tail bracket 1122. The use of the connecting structure 116 can meet two installation requirements, which reduces the number of sheet metal parts and achieves the effect of cost reduction. At the same time, there is no need to replace the connecting structure 116 during installation, which improves the convenience of assembly.

[0052] like Figure 1 , Figure 6 , Fig. 9 As shown, the frame 11 further includes a mounting structure 117, which is disposed between the left lower side tube 1112b and the right lower side tube 1113b, and the mounting structure 117 extends substantially along the width direction of the electric two-wheeled vehicle 100. The mounting structure 117 can enhance the strength of the main frame 111. At the same time, it provides a mounting position for other components. The left lower side tube 1112b, the right lower side tube 1113b and the mounting structure 117 surround and form a space, and the seat cushion assembly 15 is at least partially disposed in the space.

[0053] As an optional embodiment, the mounting structure 117 includes an extension portion 1171 and a mounting portion 1172.

[0058] like Figures 11 to 15 As shown, the vehicle body cover 12 further includes a foot assembly 121, and the foot assembly 121 includes a pedal 1211 for placing the driver's feet and a bottom edge guard plate 1212. The pedal 1211 is arranged on the main frame 111, and the pedal 1211 abuts against the front battery mounting plate 114. The bottom edge guard plate 1212 is arranged on the side of the pedal 1211. Two bottom edge guard plates 1212 are arranged, and the two bottom edge guard plates 1212 are respectively arranged on the left and right sides of the pedal 1211.

[0059] As an optional embodiment, the foot assembly 121 further includes an extended guard plate 1213, which is detachably connected to the bottom edge guard plate 1212. It is understood that when the front of the electric two-wheeled vehicle 100 does not need to place the battery 161, only the bottom edge guard plate 1212 is configured. When the front of the electric two-wheeled vehicle 100 needs to be equipped with a battery 161, the battery 161 is placed on the front battery mounting plate 114, and the extended guard plate 1213 is arranged under the bottom guard plate to increase the coverage area of ​​the foot assembly 121 along the height direction of the electric two-wheeled vehicle 100, thereby protecting and hiding the battery 161.

[0060] The side guard plate 1212 has two sizes, wherein the first size is the first side guard plate 1212a, and the second size is the second side guard plate 1212b. In the height direction of the electric two-wheeled vehicle 100, the size of the second side guard plate 1212b is larger than the size of the first side guard plate 1212a. When the front battery mounting plate 144 does not need to place the battery 161, the first side guard plate 1212a is installed. When the front battery mounting plate 144 needs to install the battery 161, the battery 161 is placed on the front battery mounting plate 114, and the second side guard plate 1212b is installed.

[0061] As an optional implementation, the second side guard plate 1212b includes a guard plate body 1212c and an extended guard plate 1212d, and the guard plate body 1212c and the extended guard plate 1212d are integrally formed.

[0062] As another optional implementation, the guard plate body 1212c and the extended guard plate 1212d are detachably connected.

[0063] like Figures 11 to 15 As shown, the front part of the pedal 1211 includes a positioning connector 1211a, and the connector 1211a is along the length direction of the electric two-wheeled vehicle 100. The pedal 1211 also includes a fixing portion 1211b for auxiliary fixing. The fixing portion 1211b is provided with a mounting hole opening along the height direction of the electric two-wheeled vehicle 100.

During installation, the clamping portion 1221a and the clamping portion 1222a cooperate to be clamped, and the first panel 1221 and the second panel 1222 are connected in a front-to-back direction of the electric two-wheeled vehicle 100. It can be understood that the number of the clamping portions 1221a can be 2 or more, and the number of the clamping portions 1222a is set to correspond to the number of the clamping portions 1221a.

[0065] As another optional implementation, the first panel 1221 includes a snap-fit ​​portion (not shown), and the second panel 1222 includes a snap-fit ​​portion (not shown), as long as the first panel 1221 and the second panel 1222 are snap-fitted. In this arrangement, the backrest assembly can be firmly connected without too many bolts or other fixings, thereby reducing the weight of the backrest assembly and making the electric two-wheeled vehicle 100 lightweight. In addition, the connection point of this connection method is relatively hidden, and the appearance of the backrest assembly is more beautiful.

[0066] Specifically, the first panel 1221 further includes an anti-slip portion 1221b, and the second panel 1222 further includes a matching portion 1222b. The anti-slip portion 1221b and the matching portion 1222b can limit the movement of the first panel 1221 and the second panel 1222 in other directions, thereby preventing slippage. Through the above arrangement, it is possible to further prevent the components of the backrest assembly 122 from falling off due to vibration during the driving of the electric two-wheeled vehicle 100, thereby improving the stability of its connection.
