[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific implementation manners of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0032] As Figure 1 and Figure 2Shown is an electric two-wheeler 100, which includes a frame 11, a suspension assembly 12, a running assembly 13, a power battery 14, a power assembly 15, and a body cover 16. The frame 11 constitutes the basic framework of the electric two-wheeler 100 and is used to support the suspension assembly 12, the running assembly 13, the power assembly 15, and the body cover 16. The suspension assembly 12 is connected to the frame 11. The suspension assembly 12 has functions of shock absorption, buffering, and guiding to transmit various forces and torques between the running assembly 13 and the frame 11, and at the same time control various vibrations of the vehicle body. The running assembly 13 is connected to the frame 11 through the suspension assembly 12, and the running assembly 13 is used for the movement of the electric two-wheeler 100. The power assembly 15 is fixedly connected to the frame 11. The power assembly 15 is drivingly connected to the running assembly 13, and the power assembly 15 can drive the running assembly 13 to move. The power battery 14 is supported by the frame 11, and the power battery 14 is used to provide electrical energy for the electric two-wheeler 100. Among them, the power battery 14 is electrically connected to the power assembly 15 so that the kinetic energy of the power battery 14 is converted into the mechanical energy of the running assembly 13. The body cover 16 is at least partially connected to the frame 11, and the body cover 16 is used to protect the internal components of the electric two-wheeler 100. To clearly illustrate the technical solution of the application, the front, rear, left, right, up, and down as shown in Figure 1 are also defined. In this application, the length direction of the frame 11 refers to the above-mentioned front-rear direction, the width direction of the frame 11 refers to the above-mentioned left-right direction, and the height direction of the frame 11 refers to the above-mentioned up-down direction.

[0033] As Figure 2 shown, as an implementation manner, the frame 11 includes a longitudinal frame 111 that extends basically along the length direction of the frame 11. The longitudinal frames 111 are also distributed along the width direction of the frame 11 and jointly form a storage space 101, and the power battery 14 is disposed in the storage space 101. Specifically, the longitudinal frame 111 constitutes the basic framework of the electric two-wheeler 100. The number of the longitudinal frames 111 is set to be multiple, and the structural strength of the longitudinal frame 111 is relatively high. Thus, by using the longitudinal frame 111 to carry the power battery 14, the stability of the power battery 14 can be improved. At the same time, the body cover 16 is connected to the longitudinal frame 111 to seal the storage space 101, which is further beneficial to protecting the power battery 14.

[0034] In this embodiment, the longitudinal frame 111 includes a front frame 1111 and a rear frame 1112 located behind the front frame 1111. The rear end of the front frame 1111 is connected to the front end of the rear frame 1112, so that the front frame 1111 and the rear frame 1112 are integrally formed, thereby improving the connection strength between the front frame 1111 and the rear frame 1112, and further improving the structural strength of the longitudinal frame 111. It should be noted that the front frame 1111 and the rear frame 1112 form a relatively large storage space 101 while meeting the structural strength requirements, so as to facilitate the installation of a relatively large power battery and / or items, which is conducive to improving the space utilization rate of the electric two-wheeler 100.

[0035] As Figure 3 shown, it should be noted that both the front frame 1111 and the rear frame 1112 are distributed on both sides of the storage space 101 along the width direction of the frame 11, and the widths of the front frame 1111 and the rear frame 1112 are different, and the width of the front frame 1111 is greater than the width of the rear frame 1112. Among them, the ratio of the maximum width W1 of the front frame 1111 along the width direction of the frame 11 to the maximum width W2 of the rear frame 1112 along the width direction of the frame 11 is greater than or equal to 1.1 and less than or equal to 1.5. Specifically, the ratio of the maximum width W1 of the front frame 1111 along the width direction of the frame 11 to the maximum width W2 of the rear frame 1112 along the width direction of the frame 11 is greater than or equal to 1.2 and less than or equal to 1.4. More specifically, the ratio of the maximum width W1 of the front frame 1111 along the width direction of the frame 11 to the maximum width W2 of the rear frame 1112 along the width direction of the frame 11 is 1.3. Through the above settings, it is possible to avoid the storage space 101 being too small due to the ratio of the maximum width W1 of the front frame 1111 along the width direction of the frame 11 to the maximum width W2 of the rear frame 1112 along the width direction of the frame 11 being too large, so as to prevent the layout space of the power battery 14 from being limited, which is conducive to improving the layout rationality of the power battery 14 and the longitudinal frame 111, and is also conducive to improving the space utilization rate of the electric two-wheeler 100; it is also possible to avoid the structural strength of the longitudinal frame 111 becoming weak due to the ratio of the maximum width W1 of the front frame 1111 along the width direction of the frame 11 to the maximum width W2 of the rear frame 1112 along the width direction of the frame 11 being too small, so as to prevent the longitudinal frame 111 from deforming under force, and further conducive to improving the structural strength of the longitudinal frame 111.

[0036] It should be noted that the maximum width W1 of the front frame 1111 in the width direction of the frame 11 is greater than or equal to 25 cm and less than or equal to 40 cm. Further, the maximum width W1 of the front frame 1111 in the width direction of the frame 11 is greater than or equal to 30 cm and less than or equal to 35 cm. Even further, the maximum width W1 of the front frame 1111 in the width direction of the frame 11 is 32.5 cm. Through the above settings, it is possible to prevent the vehicle body width from being greater than 45 mm due to the excessive maximum width W1 of the front frame 1111 in the width direction of the frame 11, so as to prevent exceeding the width range of the national standard, which is beneficial to the realization of the legality of the electric two-wheeler 100; and it is also possible to avoid the limited layout space of the power battery 14 due to the excessive small maximum width W1 of the front frame 1111 in the width direction of the frame 11, so as to prevent interference between the power battery 14 and the longitudinal frame 111, which is further beneficial to improving the space utilization rate of the electric two-wheeler 100.

[0037] As Figure 2 shown, as an implementation method, multiple power batteries 14 are provided, and the multiple power batteries 14 can be distributed in the storage space 101 along the length direction and / or the width direction of the frame 11. Specifically, since the widths of the rear frame 1112 of the front frame 1111 are different, the storage space 101 presents a layout with a wider front and a narrower rear, so that the power battery 14 needs to be reasonably assembled according to the actual situation, which is beneficial to arranging more power batteries 14 in the storage space 101, and further improving the cruising range of the electric two-wheeler 100. It should be noted that the power battery 14 can be a lead-acid battery or a lithium battery, etc., and at least three power batteries 14 are provided in the storage space 101, so that it can not only meet the normal driving of the electric two-wheeler 100, but also reserve some space for storing items, which is further beneficial to improving the storage capacity of the electric two-wheeler 100.

[0038] As Figure 4As shown, as an implementation, the vehicle frame 11 includes a battery bracket 112 and a battery carrier 113. The upper end of the battery bracket 112 is connected to the longitudinal vehicle frame 111, and the lower end of the battery bracket 112 is connected to the battery carrier 113. The battery carrier 113 is located at the lower end of the power battery 14 and bears the power battery 14. Both the power battery 14 and the battery carrier 113 are connected to the longitudinal vehicle frame 111 through the battery bracket 112. Specifically, the battery bracket 112 extends substantially along the height direction of the vehicle frame 11, and the battery bracket 112 is distributed on both sides of the power battery 14 along the width direction of the vehicle frame 11. The battery carrier 113 is located on the lower side of the longitudinal vehicle frame 111, so that the longitudinal vehicle frame 111, the battery bracket 112, and the battery carrier 113 are sequentially connected to form a storage space 101, and the opening of the storage space 101 faces upward, facilitating the installation of the power battery 14 into the storage space 101 from top to bottom, thus facilitating the assembly of the power battery 14 and further improving the assembly efficiency of the power battery 14.

[0039] In this embodiment, a pressing plate connecting portion 1113 is further provided on the longitudinal vehicle frame 111. The vehicle frame 11 further includes a battery pressing plate 114. The battery pressing plate 114 and the pressing plate connecting portion 1113 are detachably connected by fasteners. At the same time, the battery pressing plate 114 abuts against the upper side of the power battery 14 to limit the movement of the power battery 14, thereby improving the stability of the power battery 14.

[0040] Furthermore, the battery pressing plate 114 includes a first pressing plate 1141, a second pressing plate 1142, and a third pressing plate 1143. Both the first pressing plate 1141 and the third pressing plate 1143 are connected to the longitudinal vehicle frame 111, and the second pressing plate 1142 is connected between the first pressing plate 1141 and the second pressing plate 1142. Specifically, since the battery blocks 141 can be selectively installed, when it is necessary to install or disassemble some of the battery blocks 141, at least one of the first pressing plate 1141, the second pressing plate 1142, and the third pressing plate 1143 can be selectively disassembled to achieve the disassembly and assembly of the battery blocks 141, thus avoiding the disassembly of the entire battery pressing plate 114 and further improving the disassembly efficiency of the electric two-wheeler 100.

[0041] Even further, buffer blocks 1144 are provided on the battery pressing plate 114, and at least one buffer block 1144 is respectively clamped on the first pressing plate 1141, the second pressing plate 1142, and the third pressing plate 1143. The lower end of the buffer block 1144 abuts against the power battery 14. Specifically, the battery pressing plate 114 is made of metal, and the buffer block 1144 is made of rubber. The buffer block 1144 can prevent the power battery 14 from directly contacting the battery pressing plate 114, which is beneficial to protecting the power battery 14.

[0042] As an implementation, the vehicle frame 11 further includes a rear footrest bracket 1114. The rear footrest bracket 1114 is located on both sides of the longitudinal vehicle frame 111 along the width direction of the vehicle frame 11. The rear footrest bracket 1114 at least partially extends towards the longitudinal vehicle frame 111 and forms a rear footrest connection part 1114a. The rear footrest connection part 1114a is connected to the pressing plate connection part 1113. Specifically, the rear footrest bracket 1114 is used to provide foot support for the rider or driver. The rear footrest bracket 1114 is connected to the longitudinal vehicle frame 111, thereby improving the connection stability of the rear footrest bracket 1114. In addition, connecting the rear footrest connection part 1114a and the battery pressing plate 114 to the pressing plate connection part 1113 at the same time can avoid arranging too many installation points on the longitudinal vehicle frame 111, thereby improving the utilization rate of the longitudinal vehicle frame 111. It should be noted that the rear footrest bracket 1114 and the battery pressing plate 114 can be installed at the same point, which can further improve the assembly efficiency of the electric two-wheeler 100.

[0043] As Figure 1 shown, as an implementation, the electric two-wheeler 100 further includes an electrical component 17. The electrical component 17 is supported by the vehicle frame 11 and electrically connected to the power battery 14. The electrical component 17 includes all controllers, meters, or electrical appliances on the vehicle body, etc., so that the power battery 14 can provide electrical energy for the electrical component 17, and each component cooperates with each other to realize the stable operation of the electric two-wheeler 100. Among them, the body cover 16 is at least partially arranged around the power battery 14 and the electrical component 17, so as to protect the power battery 14 and the electrical component 17, and further improve the service life of the power battery 14 and the electrical component 17.

[0044] As Figure 6As shown, as an implementation, the vehicle frame 11 further includes a front footrest bracket 115 and a front footrest 116 near the front part of the longitudinal vehicle frame 111. The longitudinal vehicle frame 111 is distributed along the height direction of the vehicle frame 11 and forms an upper vehicle frame 1115 and a lower vehicle frame 1116. The front footrest bracket 115 is connected between the upper vehicle frame 1115 and the lower vehicle frame 1116, and the front footrest 116 is connected to the longitudinal vehicle frame 111 through the front footrest bracket 115. Among them, the front footrest bracket 115 and the front footrest 116 are located on both sides of the longitudinal vehicle frame 111 along the width direction of the vehicle frame 11. Specifically, when items are carried above the longitudinal vehicle frame 111, the feet of the rider need to be supported. Therefore, the front footrests 116 are provided on both sides of the longitudinal vehicle frame 111 so that the front footrests 116 can provide foot support for the rider. Through the above settings, the connection strength between the front footrest 116, the front footrest bracket 115, and the longitudinal vehicle frame 111 is relatively high, which is beneficial to improving the structural stability of the front footrest 116. At the same time, the front footrest 116 is convenient for the rider to step on, which is also beneficial to improving the driving comfort of the electric two-wheeler 100. In addition, the front footrest bracket 115 can also strengthen the connection strength between the upper vehicle frame 1115 and the lower vehicle frame 1116, which is also beneficial to improving the structural strength of the longitudinal vehicle frame 111. It should be noted that the front footrest bracket 115 and the front footrest 116 are detachably connected, and the rider can selectively install the front footrest 116 according to his own needs, which is also beneficial to improving the functional comprehensiveness of the electric two-wheeler 100.

[0045] As Figure 7 shown, in this embodiment, the front footrest bracket 115 includes a pedal clamping portion 1151 and a pedal connecting portion 1152, and the front footrest 116 includes a footrest clamping portion 1161 and a footrest connecting portion 1162 that at least partially extend in the direction close to the front footrest bracket 115. The footrest clamping portion 1161 is connected to the pedal clamping portion 1151, and the footrest connecting portion 1162 is connected to the pedal connecting portion 1152. Specifically, a pedal clamping hole that penetrates itself along the width direction of the vehicle frame 11 is provided on the pedal clamping portion 1151, a pedal connecting hole that penetrates itself along the width direction of the vehicle frame 11 is provided on the pedal connecting portion 1152, a footrest connecting hole that penetrates itself along the width direction of the vehicle frame 11 is provided on the footrest connecting portion 1162, the footrest clamping portion 1161 is clamped with the pedal clamping hole, and the pedal connecting hole and the footrest connecting hole are detachably connected through fasteners. Through the above settings, the front footrest 116 and the front footrest bracket 115 are first clamped and then connected through fasteners, thereby reducing the number of fasteners provided, which can improve the assembly efficiency of the front footrest 116 and the front footrest bracket 115.

[0046] As Figure 8As shown, as an implementation method, the vehicle body cover 16 includes a cover body 161 and a quick release plate 162, the cover body 161 is provided with a quick release hole 1611, and the quick release plate 162 covers the quick release hole 1611 and is engaged with the cover body 161. Specifically, when viewed along the width direction of the frame 11, the quick release hole 1611 is arranged around the front footrest bracket 115, that is, the front footrest bracket 115 is located in the quick release hole 1611, and the front foot pedal 116 can pass through the quick release hole 1611 to connect with the front footrest bracket 115. Through the above arrangement, the driver and passenger can selectively install or remove the front foot pedal 116 as needed. When the front foot pedal 116 is removed, the quick release hole 1611 can be sealed by the quick release plate 162, so as to prevent rainwater or dust and other substances from entering the interior of the electric two-wheeled vehicle 100 through the quick release hole 1611, which is beneficial to protecting the service life of the internal parts of the electric two-wheeled vehicle 100, and also beneficial to improving the aesthetics of the electric two-wheeled vehicle 100. In addition, the difficulty of disassembling and assembling the front foot pedal 116 can be reduced, thereby improving the assembly efficiency of the electric two-wheeled vehicle 100.

[0047] like Figure 7 As shown, the front footrest 116 includes a front footrest connecting portion 1163 and a front stepping portion 1164 rotatably connected to the front footrest connecting portion 1163, the front footrest connecting portion 1163 is connected to the front footrest bracket 115, and the front footrest connecting portion 1163 is connected to the front footrest bracket 115 through the front footrest connecting portion 1163. Specifically, when the driver needs to step on the front footrest 116, the front stepping portion 1164 rotates so that the front stepping portion 1164 extends substantially along the width direction of the frame 11, so as to facilitate the stepping of the driver. When the driver does not need to step on the front footrest 116, the front stepping portion 1164 is rotated so that the front stepping portion 1164 extends substantially along the length direction of the frame 11, so as to facilitate the storage of the front stepping portion 1164, thereby preventing the front stepping portion 1164 from contacting the ankle or leg of the driver, thereby facilitating the driving comfort of the electric two-wheeled vehicle 100.

[0048] like Figure 6 As shown, as an implementation method, a reinforcing rib 1117 is further provided between the upper frame 1115 and the lower frame 1116, and the upper frame 1115 and the lower frame 1116 are connected by the reinforcing rib 1117. Specifically, the upper end of the reinforcing rib 1117 is welded to the upper frame 1115, and the lower side of the reinforcing rib 1117 is welded to the lower frame 1116, so that the connection between the upper frame 1115 and the lower frame 1116 is more stable, which is beneficial to improve the structural strength of the longitudinal frame 111. It should be noted that the number of reinforcing ribs 1117 increases with the length of the upper frame 1115 and the lower frame 1116 to improve the connection strength between the two.

[0049] like Figure 5 andFigure 6 As shown, in this embodiment, the reinforcing rib 1117 includes an outer rib plate 1117a and an inner rib plate 1117b, and the outer rib plate 1117a is disposed close to the inner rib plate 1117b. Specifically, the inner rib plate 1117b is connected to one side of the longitudinal frame 111 close to the storage space 101, and the outer rib plate 1117a is connected to one side of the longitudinal frame 111 close to the storage space 101, thereby strengthening the structure of the longitudinal frame 111 in multiple directions. Through the above arrangement, the outer rib plate 1117a and the inner rib plate 1117b can enhance the strength of the local layout of the longitudinal frame 111, and thus contribute to enhancing the overall stability of the longitudinal frame 111.

[0050] Exemplarily, the outer rib plate 1117a and the inner rib plate 1117b are both provided with hollow holes 1117c, and the hollow holes 1117c are basically triangular through holes. Specifically, since the number of the outer rib plate 1117a and the inner rib plate 1117b is relatively large, the hollow holes 1117c can reduce the mass of the reinforcing rib 1117, and thus achieve the lightweight of the frame 11.

[0051] As Figure 4 shown, as an implementation manner, both the front footrest bracket 115 and the reinforcing rib 1117 are provided with clamping members 1118, and the electric two-wheeler 100 further includes a wire harness assembly 18. The wire harness assembly 18 is connected to the front footrest 116 and the reinforcing rib 1117 through the clamping members 1118. Specifically, the power battery 14 and the electrical components 17 are connected through the wire harness assembly 18, so as to realize the transmission of electric energy. Since the wire harness is relatively long, connection points are provided on the front footrest bracket 115 and the reinforcing rib 1117 in this embodiment, so that the clamping members 1118 can be clamped on the front footrest bracket 115 and the reinforcing rib 1117, thereby fixing the wire harness assembly 18 and further improving the stability of the wire harness assembly 18.

[0052] As Figure 5 shown, exemplarily, the front footrest bracket 115 is further provided with a limit clamping hole 1153 that penetrates through itself in the height direction of the frame 11, and the clamping member 1118 is clamped in the limit clamping hole 1153; the reinforcing rib 1117 is provided with a rib plate clamping hole 1117d, and the clamping member 1118 is clamped in the rib plate clamping hole 1117d. Through the above arrangement, the assembly speed of the clamping member 1118 and the front footrest bracket 115 can be improved, and the assembly speed of the clamping member 1118 and the reinforcing rib 1117 can also be improved, which is beneficial to improving the assembly efficiency of the wire harness assembly 18.

[0053] As an implementation, the edge of the reinforcing rib 1117 is set as an arc edge 1117e, and at least part of the wire harness assembly 18 abuts against the arc surface formed by the arc edge 1117e, so that the arc edge 1117e is arranged away from the wire harness assembly 18. Specifically, since the edges of the outer rib plate 1117a and the inner rib plate 1117b are very sharp, it is easy to damage the structure of the wire harness assembly 18. Therefore, in this application, the edge of the outer rib plate 1117a is bent towards the inner rib plate 1117b, and the edge of the inner rib plate 1117b is bent towards the outer rib plate 1117a, so as to prevent the wire harness assembly 18 from directly contacting the edge of the outer rib plate 1117a or the edge of the inner rib plate 1117b, which is beneficial to protecting the wire harness assembly 18.

[0054] As Figure 5 shown, as an implementation, the frame 11 further includes a rear support frame 117 located behind the electric two-wheeler 100. The rear end of the longitudinal frame 111 is connected to the rear support frame 117, and a reinforcing piece 1171 is further provided on the rear side of the rear support frame 117. The reinforcing piece 1171 is fixedly connected to the rear support frame 117. Specifically, the rear support frame 117 is used to support the rear part components of the electric two-wheeler 100. Therefore, it is necessary to improve the structural strength of the rear support frame 117. In this application, the reinforcing piece 1171 is made of sheet metal, and the reinforcing piece 1171 has a large volume and high strength, which is beneficial to improving the structural strength of the rear support frame 117.

[0055] In this embodiment, an electrical bracket 1172 is further provided at the upper end of the rear support frame 117. The electrical assembly 17 includes an air switch 171 and a meter 172. The air switch 171 and the meter 172 are connected to the rear support frame 117 through the electrical bracket 1172. Specifically, the air switch 171 is connected to the power battery 14. The air switch 171 serves as the main switch of the electric two-wheeler 100, and the meter 172 is a tool for detecting the performance of the power battery 14. In this application, the air switch 171 and the meter 172 are integrated on the electrical bracket 1172. When it is necessary to repair and replace the air switch 171 and the meter 172, the air switch 171 and the meter 172 can be quickly disassembled and assembled by disassembling and assembling the electrical bracket 1172, which is beneficial to improving the disassembly efficiency of the air switch 171 and the meter 172. In addition, the structures of the air switch 171 and the meter 172 are compact, which is beneficial to improving the structural compactness of the air switch 171 and the meter 172. At the same time, the air switch 171 and the meter 172 occupy a small body space, which is also beneficial to improving the space utilization rate of the electric two-wheeler 100.

[0056] As Figure 8As shown, as an implementation, the body covering 16 includes a footrest box 163 for carrying the power battery 14. The footrest box 163 is at least partially located in the storage space 101 and is connected to the longitudinal frame 111. Specifically, the footrest box 163 itself has an integrated structure, so that the structural strength of the footrest box 163 is relatively high. The power battery 14 is located inside the footrest box 163 to prevent the power battery 14 from vibrating up and down, thereby improving the safety of the power battery 14. At the same time, the upper end of the footrest box 163 is located above the longitudinal frame 111, so that the footrest box 163 also has a stepping function, which is beneficial to improving the functional diversity of the footrest box 163.

[0057] As Figure 9 shown, in this embodiment, the footrest box 163 includes a footrest body 1631 and a footrest cover 1632. The footrest body 1631 forms a battery space 102, and the power battery 14 is arranged in the battery space 102. A battery installation opening 1630 communicating with the battery space 102 is formed on the footrest body 1631, and the footrest cover 1632 is rotatably connected to the footrest body 1631 and covers the battery installation opening 1630. Specifically, the power battery 14 is installed in the battery space 102 through the battery installation opening 1630. When it is necessary to disassemble and assemble the power battery 14, the footrest cover 1632 can be rotated from the horizontal state to the vertical state, so as to facilitate the assembly of the power battery 14 into the battery space 102 or the removal from the battery space 102, and then the footrest cover 1632 is rotated from the vertical state to the horizontal state. Through the above settings, the assembly speed of the power battery 14 and the footrest box 163 can be improved. In addition, the footrest cover 1632 is basically located at the upper end of the longitudinal frame 111, and the footrest cover 1632 has relatively high strength, so as to support the feet of the driver and passengers, which is beneficial to improving the structural strength of the footrest box 163.

[0058] As Figure 6 and Figure 9 shown, as an implementation, the footrest body 1631 includes a box body connection part 1631a, and the longitudinal frame 111 includes a frame connection part 1119. The box body connection part 1631a is detachably connected to the frame connection part 1119. Specifically, along the width direction of the frame 11, the footrest body 1631 at least partially extends away from the power battery 14 to form a box body connection part 1631a. The box body connection part 1631a is located above the frame connection part 1119, so as to facilitate the longitudinal frame 111 to carry the footrest box 163, thereby improving the connection stability between the footrest box 163 and the longitudinal frame 111. It can be understood that when observed along the height direction of the frame 11, the box body connection part 1631a and the frame connection part 1119 at least partially overlap.

[0059] In this embodiment, a box body rotating part 1631b is provided on the front side of the footrest body 1631, and a cover plate rotating part 1632a is provided on the front side of the footrest cover plate 1632. The cover plate rotating part 1632a is rotatably connected to the box body rotating part 1631b. Specifically, a rotating shaft is passed through the cover plate rotating part 1632a and the box body rotating part 1631b, and the rotating shaft extends along the width direction of the vehicle frame 11, so that the footrest cover plate 1632 can be turned forward or backward with the width direction of the vehicle frame 11 as the rotation center. Through the above settings, the footrest box 163 can be opened or closed, which is convenient for the assembly of the power battery 14, thereby improving the assembly efficiency of the power battery 14.

[0060] Furthermore, a box body locking part 1631c is provided at one end of the footrest body 1631 away from the box body connecting part 1631a, and a cover plate locking part 1632b is provided at one end of the footrest cover plate 1632 away from the cover plate rotating part 1632a. The footrest box 163 includes an open state (see Figure 9 ) and a closed state (see Figure 8 ). When the footrest box 163 is in the open state, the cover plate locking part 1632b abuts against the box body locking part 1631c. When the footrest box 163 is in the closed state, the cover plate locking part 1632b is separated from the box body locking part 1631c. Specifically, when the footrest cover plate 1632 and the footrest body 1631 are in the closed state, the footrest cover plate 1632 is in a horizontal state. At this time, the cover plate locking part 1632b abuts against the box body locking part 1631c, so that the footrest body 1631 can better bear the footrest cover plate 1632.

[0061] Even further, a vehicle lock structure 1633 is provided on the box body locking part 1631c, and a lock ring 1634 is provided on the cover plate locking part 1632b. The lock ring 1634 passes through the box body locking part 1631c and is clamped with the vehicle lock structure 1633. Through the above settings, it is possible to prevent the footrest cover plate 1632 from being separated from the footrest body 1631 due to road conditions, which is beneficial to improving the connection strength between the footrest body 1631 and the footrest cover plate 1632.

[0062] As a realization method, the footrest box 163 further includes a footrest plate 1635. The footrest plate 1635 is at least partially provided above the footrest cover plate 1632 and is connected to the footrest cover plate 1632. Specifically, the footrest plate 1635 is in direct contact with the feet of the driver and passenger. Therefore, in this application, the footrest plate 1635 and the footrest cover plate 1632 are integrally arranged, which can not only provide high structural strength of the footrest cover plate 1632, but also avoid setting too many connection points to install the footrest plate 1635, so that the footrest box 163 has both the function of protecting the power battery 14 and providing a stepping place for the driver and passenger, thereby improving the functional diversity of the footrest box 163.

[0063] As an implementation, a box body clamping groove 1631d is further provided on the pedal body 1631. The box body clamping groove 1631d is located in the battery space 102. The pedal box 163 further includes a clamping strip 1636. At least part of the clamping strip 1636 abuts against the upper end of the power battery 14, and the clamping strip 1636 is clamped with the box body clamping groove 1631d. Specifically, the clamping strip 1636 can provide a supporting force for the pedal cover plate 1632, and at the same time can limit the movement of the power battery 14 in the battery space 102, thereby improving the stability of the power battery 14 and the structural strength of the pedal cover plate 1632.

[0064] In this embodiment, an installation clamping hole 1636a extending in the height direction of the vehicle frame 11 is formed on the clamping strip 1636. A buffer member 1636b is further provided between the clamping strip 1636 and the power battery 14. The upper end of the buffer member 1636b is connected to the installation clamping hole 1636a, and the lower end of the buffer member 1636b abuts against the power battery 14. Through the above settings, the buffer member 1636b can buffer the mutual acting force between the power battery 14 and the clamping strip 1636, thereby playing a protective role for the power battery 14 and further improving the safety of the power battery 14.

[0065] As Figure 10 shown, as an implementation, a protection plate 1637 is further provided at the front end of the pedal body 1631. The protection plate 1637 forms a protection space 1637a. The protection plate 1637 is connected to the pedal body 1631, and the front end of the pedal cover plate 1632 is located in the protection space 1637a. Specifically, a channel is formed at the front end of the pedal body 1631. The front end of the pedal cover plate 1632 passes through the channel and is located outside the pedal body 1631. Therefore, in this application, the protection plate 1637 is used to seal the channel of the pedal body 1631, which is beneficial to improving the sealing performance of the pedal body 1631.

[0066] As Figure 1 、 Figure 11 and Figure 12As shown, as an implementation, the electric two-wheeler 100 includes a saddle assembly 19, which is supported by a vehicle frame 11, and the saddle assembly 19 is rotatably connected to a body covering 16. Specifically, the vehicle frame 11 includes a transverse bracket 118 extending in the width direction of the vehicle frame 11. The transverse bracket 118 is located below the saddle assembly 19. Along the height direction of the vehicle frame 11, a power battery 14 is located between the saddle assembly 19 and the transverse bracket 118, and the transverse bracket 118 is used to carry the power battery 19. The saddle assembly 19 includes a seating surface 190 and a support surface 191 disposed opposite to the seating surface 190, and the support surface 191 is disposed close to the power battery 14. More specifically, the body covering 16 includes a battery housing 164 for carrying the power battery 14. The power battery 14 is installed in the battery housing 164, and the battery housing 164 is connected to the transverse bracket 118. The saddle assembly 19 is located at the upper end of the battery housing 164 and is connected to the battery housing 164. Through the above arrangement, the transverse bracket 118 can support the battery housing 164 and the saddle assembly 19, and the battery housing 164 can carry the saddle assembly 19, thereby improving the connection stability among the saddle assembly 19, the battery housing 164, and the transverse bracket 118.

[0067] As Figure 12 shown, in this embodiment, the body covering 16 further includes an adjusting plate 165. The adjusting plate 165 is located between the power battery 14 and the saddle assembly 19. The adjusting plate 165 is detachably connected to the support surface 191, and the lower end of the adjusting plate 165 abuts against the power battery 14. Specifically, there are differences in the volume sizes of the power batteries 14, but the internal space of the battery housing 164 is fixed. In order to enable the power battery 14 to be stably assembled in the battery housing 164, an adjusting plate 165 is provided between the power battery 14 and the saddle assembly 19, so that the saddle assembly 19 abuts against the upper end of the power battery 14 through the adjusting plate 165, thereby restricting the movement of the power battery 14. Through the above arrangement, the connection stability between the power battery 14 and the battery housing 164 can be improved. At the same time, the battery housing 164 can be adapted to different specifications of the power batteries 14, so that the electric two-wheeler 100 can be installed with a large-capacity power battery 14, which is beneficial to improving the endurance of the electric two-wheeler 100. It should be noted that the thickness of the adjusting plate 165 can be appropriately adjusted according to the size of the power battery 14 so that the adjusting plate 165 can abut against the power battery 14.

[0068] Exemplarily, the lower end of the adjusting plate 165 extends at least partially towards the power battery 14 to form a convex portion 1651. A number of convex blocks 1652 are provided on the convex portion 1651. The convex blocks 1652 extend towards the power battery 14, and the lower ends of the convex blocks 1652 abut against the upper end of the power battery 14. Specifically, both the convex portion 1651 and the convex blocks 1652 are used to increase the thickness of the adjusting plate 165, which is beneficial to reducing the volume of the adjusting plate 165. At the same time, it also reduces the contact area between the adjusting plate 165 and the power battery 14, thereby improving the space utilization rate of the electric two-wheeler 100.

[0069] In the above embodiment, a convex through hole 1652a penetrating through itself is formed on the convex block 1652. The adjusting plate 165 includes a rubber plug 1653. The upper end of the rubber plug 1653 is clamped in the convex through hole 1652a, and the lower end of the rubber plug 1653 abuts against the power battery 14. Through the above arrangement, the rubber plug 1653 can buffer the mutual acting force between the power battery 14 and the convex block 1652, which is beneficial to protecting the convex block 1652 and the power battery 14, and thereby extending the service life of the electric two-wheeler 100.

[0070] As a implementation method, a number of support connection parts 192 are provided on the support surface 191, and a number of adjusting connection parts 1654 corresponding to the support connection parts 192 are provided on the adjusting plate 165. The support connection parts 192 and the adjusting connection parts 1654 are detachably connected by fasteners. Through the above arrangement, the disassembly method of the support connection parts 192 and the adjusting connection parts 1654 is simple, which is beneficial to replacing the adjusting plate 165, and thereby improving the assembly efficiency of the adjusting plate 165.

[0071] In this embodiment, the support surface 191 extends at least partially away from the adjusting plate 165 to form a number of limiting grooves 1911, and the adjusting plate 165 extends at least partially towards the support surface 191 to form a number of clamping points 1655. The clamping points 1655 can be clamped in the limiting grooves 1911. Through the above arrangement, the clamping points 1655 and the limiting grooves 1911 are first clamped to limit the positions of the adjusting plate 165 and the support surface 191, and then reinforced by fasteners, which is beneficial to improving the connection strength between the support surface 191 and the adjusting plate 165.

[0072] As Figure 13 shown, as a implementation method, a number of weight reduction and strengthening grooves 1656 are provided at one end of the adjusting plate 165 close to the connecting saddle assembly 19. The openings of the weight reduction and strengthening grooves 1656 abut against the support surface 191. Specifically, the weight reduction and strengthening grooves 1656 are formed by splicing a number of rib plates, which can not only reduce the volume of the adjusting plate 165, but also improve the structural strength of the adjusting plate 165.

[0073] As Figure 12 shown, exemplarily, a support surface through-hole 1912 having the same diameter as the convex through-hole 1652a is provided on the support surface 191. When the adjusting plate 165 is separated from the support surface 191, the rubber plug 1653 can be clamped in the support surface through-hole 1912. Specifically, when the volume of the power battery 14 is relatively large and the adjusting plate 165 is installed on the saddle assembly 19, thus the present application also provides another embodiment. By integrating the rubber plug 1653 on the support surface 191, the assembly of the power battery 14 with a relatively large volume can be satisfied, thereby facilitating the improvement of the adaptability of the electric two-wheeler 100.

[0074] As Figure 13 shown, as a realization manner, at least a part of the convex portion 1651 extends towards the direction close to the power battery 14 to form a safety block 1657. The wire harness assembly 18 further includes a plug connector 181. The lower end of the plug connector 181 is clamped with the power battery 14, and the lower end of the safety block 1657 abuts against the upper end of the plug connector 181. Specifically, the plug connector 181 is used for transmitting the electric energy of the power battery 14, and the plug connector 181 is clamped on the upper end of the power battery 14. Through the above arrangement, the safety block 1657 can prevent the plug connector 181 from being separated from the power battery 14, so that the electric energy of the power battery 14 can be stably output, and further improve the safety performance of the electric two-wheeler 100.

[0075] As Figure 12 shown, in this embodiment, a safety through-hole 1657a penetrating through itself is formed in the safety block 1657. The adjusting plate 165 further includes a protective rubber 1658. The protective rubber 1658 is clamped in the safety through-hole 1657a, and the lower end of the protective rubber 1658 abuts against the plug connector 181. Through the above arrangement, the protective rubber 1658 can buffer the mutual acting force between the safety block 1657 and the plug connector 181, thereby better protecting the plug connector 181 and further improving the service life of the plug connector 181.

[0076] As Figure 11As shown, as an implementation, the vehicle frame 11 further includes a reinforcing bracket 119. The rear support frame 117 is distributed along the width direction of the vehicle frame 11. Both ends of the transverse bracket 118 are connected to the rear support frame 117, and both ends of the reinforcing bracket 119 are respectively connected to the rear support frame 117 and the transverse bracket 118. Specifically, the transverse bracket 118 and the rear support frame 117 are connected to each other, and multiple mounting points are provided on the transverse bracket 118 and the rear support frame 117. Therefore, the structural strength requirements for the transverse bracket 118 and the rear support frame 117 are relatively high. In this application, the structural stability of the transverse bracket 118 and the rear support frame 117 can be improved through the reinforcing bracket 119, thereby improving the structural strength of the vehicle frame 11. In addition, both ends of the reinforcing bracket 119 can also be respectively connected to the longitudinal bracket 111 and the transverse bracket 118, and the same effect can be achieved, which will not be elaborated here.

[0077] As Figure 14 Shown, this application also provides an electric motorcycle 200. The body structure of this electric motorcycle 200 is basically the same as that of the electric two-wheeler 100. It should be noted that the electric motorcycle 200 includes a saddle assembly 20. Along the length direction of the vehicle frame 11, the length of the saddle assembly 20 is greater than the length of the saddle assembly 19 of the electric two-wheeler 100.

[0078] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
