Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an electric two-wheeled vehicle. Background Technology

[0002] With increasingly stringent requirements for environmental protection and energy conservation, the number of electric two-wheelers is gradually increasing. Compared to gasoline-powered two-wheelers, electric two-wheelers have a shorter range, thus requiring an increase in battery capacity to improve their range.

[0003] In the existing technology, due to the small size of electric two-wheelers, it is difficult to arrange large-volume batteries and multiple batteries cannot be arranged. Therefore, it is necessary to increase the battery arrangement space of electric two-wheelers. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this application is to provide an electric two-wheeled vehicle with a large power battery storage space.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An electric two-wheeled vehicle includes a frame, a body panel, a running gear assembly, a drive assembly, and a power battery. The body panel is located on the frame and fixedly connected to it. The running gear assembly is at least partially located below the frame. The drive assembly is supported by the frame and is drive-connected to the running gear assembly. The power battery is supported by the frame and electrically connected to the drive assembly. The frame includes a front tube, a side tube assembly, a surround tube assembly, and a rear tube assembly. The side tube assembly and the surround tube assembly are at least partially located between the front tube and the rear tube assembly, and are fixedly connected to the front tube and the rear tube assembly, respectively. The side tube assembly is located above the surround tube assembly, and when viewed along the height direction of the electric two-wheeled vehicle, the side tube assembly and the surround tube assembly substantially overlap. At least a portion of the front tube, side tube assembly, surround tube assembly, and rear tube assembly surround to form a receiving space, and the power battery is located within the receiving space. The front tube and rear tube assemblies extend substantially along the height direction of the electric two-wheeled vehicle, and when viewed along the height direction of the electric two-wheeled vehicle, the front tube and rear tube assemblies do not overlap with the receiving space.

[0007] Furthermore, the side tube assembly includes a middle section extending substantially along the length direction of the electric two-wheeler and a front section extending substantially along the height direction of the electric two-wheeler. The front section is located substantially in front of the middle section and is fixedly connected to the front tube. When viewed along the height direction of the electric two-wheeler, the front section is set substantially perpendicular to the middle section.

[0008] Furthermore, the electric two-wheeler also includes a rear rocker arm, which is rotatably connected to the rear tube assembly. The connection point between the rear tube assembly and the rear rocker arm is defined as the rocker arm mounting point. There are two rocker arm mounting points, which are distributed basically along the width direction of the electric two-wheeler. When viewed along the height direction of the electric two-wheeler, the rocker arm mounting points are basically located on both sides of the accommodating space and do not overlap with the accommodating space.

[0009] Furthermore, the side tube assembly also includes a rear section located behind the middle section. The rear section and the middle section are integrally formed, and the rear section extends basically along the height direction of the electric two-wheeler. The rear section is fixedly connected to the rear tube assembly, and the connection point between the rear section and the rear tube assembly is basically located above the rocker arm mounting point.

[0010] Furthermore, the enclosure tube assembly includes a first enclosure tube and a second enclosure tube distributed along the width direction of the electric two-wheeler. The rear ends of the first enclosure tube and the second enclosure tube are connected to each other, and the front ends of the first enclosure tube and the second enclosure tube are fixedly connected through a front tube. The enclosure tube assembly also includes a support plate, which is located between the first enclosure tube and the second enclosure tube and is fixedly connected to the first enclosure tube and the second enclosure tube. The power battery is located on the support plate.

[0011] Furthermore, the side tube assembly includes a first side tube and a second side tube distributed along the width direction of the electric two-wheeler, and the body panel includes a foot support plate located between the first side tube and the second side tube and detachably connected to the first side tube and the second side tube.

[0012] Furthermore, the electric two-wheeler also includes a battery pressure plate, which is located below the foot support plate and fixedly connected to it; an elastic element is provided below the battery pressure plate, which abuts against the power battery when the power battery is in the installation state and provides a pre-tightening force between the power battery and the battery pressure plate to keep them apart.

[0013] Furthermore, the electric two-wheeler also includes a battery mounting plate and rollers. The rollers are located below the battery mounting plate and are rotatably connected to it. The two ends of the battery mounting plate are connected to the first side tube and the second side tube, respectively. Viewed from the height of the electric two-wheeler, the accommodating space is at least partially located behind the battery mounting plate. The foot support plate is located primarily in front of the battery mounting plate. The electric two-wheeler also includes a battery lock located on the battery mounting plate, used to control the locking or unlocking of the battery pressure plate and the battery mounting plate.

[0014] Furthermore, the electric two-wheeler includes electrical components, a battery connector, and an adapter connector. The battery connector is electrically connected to the electrical components and the drive assembly, and the adapter connector is electrically connected to the battery connector and the power battery. The adapter connector and the battery connector are at least partially located inside the receiving space. The frame also includes a central transverse tube that extends substantially along the width direction of the electric two-wheeler. The central transverse tube is located between and fixedly connected to the first and second side tubes, and the adapter connector is fixedly connected to the central transverse tube.

[0015] Furthermore, the rear tube assembly includes a first rear tube and a second rear tube distributed along the width direction, and the frame also includes a rear cross tube, which is substantially located between the first rear tube and the second rear tube; the rear cross tube is located behind the middle cross tube and substantially above the middle cross tube; the electric two-wheeler also includes a seat bucket, which is at least partially located between the middle cross tube and the rear cross tube, and the seat bucket is also at least partially located between the first rear tube and the second rear tube.

[0016] The front and rear tube assemblies of the aforementioned electric two-wheeler extend basically along the height direction of the electric two-wheeler. When viewed along the height direction of the electric two-wheeler, the front and rear tube assemblies do not overlap with the housing space, thereby avoiding the front and rear tube assemblies restricting the volume of the housing space and increasing the placement space for the power battery. At the same time, when viewed along the height direction of the electric two-wheeler, the side tube assembly and the surrounding tube assembly basically overlap, thereby avoiding the surrounding tube assembly restricting the volume of the housing space and increasing the placement space for the power battery.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, an electric two-wheeler 100 includes a frame 11, a body panel 12, a running gear 13, a suspension assembly 14, a drive assembly 15, a power battery 16, and a seat assembly 17. The frame 11 serves as the basic framework of the electric two-wheeler 100, supporting the body panel 12, running gear 13, suspension assembly 14, drive assembly 15, power battery 16, and seat assembly 17. The body panel 12 is at least partially located on and fixedly connected to the frame 11. The suspension assembly 14 is at least partially mounted on the frame 11, and the running gear 13 is connected to the frame 11 via the suspension assembly 14. The drive assembly 15 is supported by the frame 11 and is drive-transmitted to the running gear 13, thereby transmitting power from the drive assembly 15 to the running gear 13, enabling the running gear 13 to drive the electric two-wheeler 100. The power battery 16 is supported by the frame 11 and electrically connected to the drive assembly 15, providing energy to the drive assembly 15. The saddle assembly 17 is supported by the frame 11 and is used to provide support for the driver.

[0032] Specifically, the running gear 13 is at least partially located below the frame 11 to prevent interference between the running gear 13 and other components of the electric two-wheeler 100, thus facilitating its normal operation. The running gear 13 includes a front wheel 131 and a rear wheel 132. The suspension assembly 14 includes a front suspension 141 and a rear swingarm 142. The front suspension 141 connects the front wheel 131 to the frame 11, and the rear swingarm 142 connects the rear wheel 132 to the frame 11. The drive assembly 15 is drively connected to the rear wheel 132 to drive its rotation. Both the front wheel 131 and the rear wheel 132 are at least partially located below the frame 11.

[0033] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, back, left, right, up, and down. In this application, the length direction of the electric two-wheeled vehicle 100 refers to... Figure 1 In the forward and backward direction, the 100 width direction of the electric two-wheeler refers to... Figure 1 The left and right directions in the middle, and the 100 height direction of the electric two-wheeler refer to Figure 1 The up and down directions in the middle.

[0034] like Figure 2 and Figure 3 As shown, in one implementation, the frame 11 includes a front tube 111, a side tube assembly 112, a rear tube assembly 113, and a surround tube assembly 114. The side tube assembly 112 and the surround tube assembly 114 are at least partially located between the front tube 111 and the rear tube assembly 113. The side tube assembly 112 is fixedly connected to the front tube 111 and the rear tube assembly 113, and the surround tube assembly 114 is fixedly connected to the front tube 111 and the rear tube assembly 113. Specifically, the side tube assembly 112 is located above the surround tube assembly 114. The front end of the side tube assembly 112 is connected to the front tube 111, and the rear end of the side tube assembly 112 is connected to the rear tube assembly 113. The rear tube assembly 113 is located behind the side tube assembly 112. The front end of the surround tube assembly 114 is connected to the front tube 111, and the rear end of the surround tube assembly 114 is connected to the rear tube assembly 113, so that the front tube 111, the side tube assembly 112, the rear tube assembly 113 and the surround tube assembly 114 constitute the basic frame of the frame 11.

[0035] At least a portion of the front tube 111, the side tube assembly 112, the surrounding tube assembly 114, and the rear tube assembly 113 surround and form a receiving space 110, within which the power battery 16 is located.

[0036] The front tube 111 and the rear tube assembly 113 extend substantially along the height direction of the electric two-wheeler 100. When viewed along the height direction of the electric two-wheeler 100, the front tube 111 and the rear tube assembly 113 do not overlap with the housing space 110, thereby avoiding the front tube 111 and the rear tube assembly 113 restricting the volume of the housing space 110, so as to increase the arrangement space of the power battery 16.

[0037] Viewed along the height of the electric two-wheeler 100, the side tube assembly 112 and the surrounding tube assembly 114 basically overlap, thereby avoiding the surrounding tube assembly 114 from restricting the volume of the accommodating space 110, so as to increase the arrangement space of the power battery 16.

[0038] Specifically, the side tube assembly 112 includes a first side tube 1121 and a second side tube 1122, which are distributed substantially along the width direction of the electric two-wheeler 100. The rear tube assembly 113 includes a first rear tube 1131 and a second rear tube 1132, which are also distributed along the width direction of the electric two-wheeler 100. The surrounding tube assembly 114 includes a first surrounding tube 1141, a second surrounding tube 1142, and at least one support plate 1143. The first surrounding tube 1141 and the second surrounding tube 1142 are distributed substantially along the width direction of the electric two-wheeler 100. The support plate 1143 is located between the first surrounding tube 1141 and the second surrounding tube 1142, and the support plate 1143 is used to support the power battery 16, so that the power battery 16 can be located on the support plate 1143. Along the length of the electric two-wheeler 100, a first side tube 1121 is located between the front tube 111 and the first rear tube 1131, and a second side tube 1122 is located between the front tube 111 and the second rear tube 1132. The first side tube 1121 is connected to the front tube 111 and the first rear tube 1131, and the second side tube 1122 is connected to the front tube 111 and the second rear tube 1132. The front ends of the first surrounding tube 1141 and the second surrounding tube 1142 are fixedly connected to the front tube 111, and the rear ends of the first surrounding tube 1141 and the second surrounding tube 1142 are connected to each other. The lower end of the first rear tube 1131 is connected to the first surrounding tube 1141, and the lower end of the second rear tube 1132 is connected to the second surrounding tube 1142. The support plate 1143 is also fixedly connected to the first surrounding tube 1141 and the second surrounding tube 1142.

[0039] In this embodiment, the front tube 111, the first side tube 1121, the second side tube 1122, the first rear tube 1131 and the second rear tube 1132, the first surrounding tube 1141, the second surrounding tube 1142 and the support plate 1143 surround and form a receiving space 110 for accommodating the power battery 16, that is, the lower part of the frame 11 forms a receiving space 110.

[0040] More specifically, viewed along the height of the electric two-wheeler 100, the first surrounding tube 1141 and the first side tube 1121 substantially overlap, and the second surrounding tube 1142 and the second side tube 1122 substantially overlap, thereby preventing the surrounding tube assembly 114 from restricting the volume of the accommodating space 110, thus increasing the arrangement space for the power battery 16. Furthermore, the above arrangement also prevents the surrounding tube assembly 114 from extending beyond the edge of the side tube assembly 112, thereby preventing the surrounding tube assembly 114 from becoming too large and causing the frame 11 to become too large, thus improving the structural compactness of the frame 11. In this embodiment, the first side tube 1121 is located above the first surrounding tube 1141, and the second side tube 1122 is located above the second surrounding tube 1142.

[0041] In this embodiment, the structure of the first side tube 1121 is basically the same as that of the second side tube 1122. A longitudinal plane 101 is defined that is perpendicular to the width direction of the electric two-wheeled vehicle 100 and substantially bisects the electric two-wheeled vehicle 100 (see reference). Figure 4 The first side tube 1121 and the second side tube 1122 are basically symmetrically arranged about the longitudinal plane 101. This application describes the first side tube 1121 as an example, and the structure of the second side tube 1122 will not be described in detail.

[0042] like Figure 3 and Figure 4 As shown, in one implementation, the first side tube 1121 includes a front section 1121a, a middle section 1121b, and a rear section 1121c. The front section 1121a, middle section 1121b, and rear section 1121c are integrally formed. The front section 1121a is located substantially in front of the middle section 1121b, and the rear section 1121c is located substantially behind the middle section 1121b. Along the length of the electric two-wheeled vehicle 100, the middle section 1121b is located between the front section 1121a and the rear section 1121c. The front section 1121a is also fixedly connected to the front tube 111, and the rear section 1121c is also fixedly connected to the first rear tube 1131.

[0043] Specifically, the front section 1121a extends substantially along the height direction of the electric two-wheeler 100, and the middle section 1121b extends substantially along the length direction of the electric two-wheeler 100. Viewed from the height direction of the electric two-wheeler 100, the front section 1121a and the middle section 1121b are set substantially perpendicularly, so that the front part of the first side tube 1121 extends substantially in an "L" shape, thereby increasing the space at the turning point of the front section 1121a and the middle section 1121b, that is, increasing the space at the front of the first side tube 1121, so that the electric two-wheeler 100 can use the space at the front of the first side tube 1121 to arrange the power battery 16, thereby expanding the volume of the accommodating space 110.

[0044] It should be noted that an arc-shaped transition section can be provided between the front section 1121a and the middle section 1121b, which facilitates the processing of the front section 1121a and the middle section 1121b and helps to improve the stress on the front section 1121a and the middle section 1121b, thereby increasing the structural strength of the front section 1121a and the middle section 1121b.

[0045] like Figure 2 and Figure 3 As shown, in this embodiment, the rear rocker arm 142 is rotatably connected to the rear tube assembly 113. The connection point between the rear tube assembly 113 and the rear rocker arm 142 is defined as the rocker arm mounting point 1133. The rear rocker arm 142 is basically "H"-shaped and includes a central crossbeam 1421 and two rocker arm bodies 1422. The central crossbeam 1421 extends basically along the width direction of the electric two-wheeled vehicle 100 and is located behind the side tube assembly 112. The central crossbeam 1421 is connected to the two rocker arm bodies 1422, and both rocker arm bodies 1422 are rotatably connected to the rear tube assembly 113.

[0046] To further increase the volume of the accommodating space 110, the two rocker arm bodies 1422 of this application are rotatably connected to the first rear tube 1131 and the second rear tube 1132, respectively. Therefore, there are two rocker arm mounting points 1133 between the rear rocker arm 142 and the rear tube assembly 113, and the two rocker arm mounting points 1133 are distributed basically along the width direction of the electric two-wheeled vehicle 100. Viewed along the height direction of the electric two-wheeled vehicle 100, the two rocker arm mounting points 1133 are basically located on both sides of the accommodating space 110 and do not overlap with the accommodating space 110. Specifically, the two rocker arm mounting points 1133 are located on the first rear tube 1131 and the second rear tube 1132, respectively, and are located behind the first rear tube 1131 and the second rear tube 1132, respectively. This arrangement avoids the rocker arm mounting points 1133 being located within the accommodating space 110, thus preventing interference between the rocker arm mounting points 1133 and the power battery 16.

[0047] Understandably, to ensure an effective rotational connection between the rear swingarm 142 and the frame 11, the rotational connection axes between the two swingarm bodies 1422 and the first rear tube 1131 and the second rear tube 1132 are substantially aligned on the same straight line. Viewed along the height of the electric two-wheeler 100, the rotational axis between the rear swingarm 142 and the rear tube assembly 113 at least partially overlaps with the receiving space 110. Specifically, viewed from the height of the electric two-wheeler 100, the rotational axis between the swingarm body 1422 and the first rear tube 1131 at least partially overlaps with the receiving space 110. Viewed from the height of the electric two-wheeler 100, the swingarm body 1422 substantially overlaps with the first rear tube 1131 and the second rear tube 1132, meaning that in the width direction of the electric two-wheeler 100, the swingarm body 1422 and the receiving space 110 do not substantially interfere with each other. This arrangement effectively extends the storage space 110 of the power battery 16 to the rear end of the frame 11, further increasing the volume of the storage space 110 while avoiding interference with the connection between the frame 11 and the rear swing arm 142, or affecting the rotation performance of the rear swing arm 142. This facilitates the placement of a larger power battery 16 and improves the range of the electric two-wheeler 100.

[0048] Optionally, the rear section 1121c extends substantially along the height direction of the electric two-wheeler 100. The rear section 1121c is fixedly connected to the rear tube assembly 113. Specifically, the rear section 1121c is fixedly connected to the first rear tube 1131, and the end of the rear section 1121c away from the first rear tube 1131 is integrally formed with the middle section 1121b. The connection point between the rear section 1121c and the rear tube assembly 113 is substantially located above the rocker arm mounting point 1133, that is, the connection point between the rear section 1121c and the first rear tube 1131 is substantially located above the rocker arm mounting point 1133.

[0049] like Figure 5 As shown, specifically, when the connection between the rear section 1121c and the first rear tube 1131 is located above the rocker arm mounting point 1133, the force on the first rear tube 1131 can be more balanced, thereby preventing the first rear tube 1131 from deforming or breaking due to stress. Furthermore, the above arrangement can reduce the number of additional reinforcing components at the connection between the first rear tube 1131 and the rear section 1121c, thereby simplifying the structure of the frame 11, achieving a lighter frame 11, and improving the structural compactness of the frame 11.

[0050] To better secure the power battery 16, the electric two-wheeler 100 also includes a battery mounting assembly 18 for securing the power battery 16 (see reference). Figure 2 The battery mounting assembly 18 includes a battery compartment 181 (see reference). Figure 2The battery compartment 181 can be a frame structure made of plastic parts. The interior of the battery compartment 181 is hollow, which facilitates the placement of the power battery 16. The battery compartment 181 is located on the support plate 1143, so that the battery compartment 181 is located in the receiving space 110. The battery compartment 181 is also fixedly connected to the support plate 1143. The upper part of the battery compartment 181 has an opening. During the assembly process of the power battery 16 and the battery compartment 181, the power battery 16 passes through the opening of the battery compartment 181 and is located in the battery compartment 181. The inner contour of the battery compartment 181 is basically consistent with the outer contour of the power battery 16, so as to facilitate the fixing of the power battery 16 by the battery compartment 181.

[0051] like Figure 3 As shown, in one implementation, the frame 11 also includes a reinforcing member 115. The reinforcing member 115 is located between the first surrounding tube 1141 and the first side tube 1121, and also between the second surrounding tube 1142 and the second side tube 1122. This allows the reinforcing member 115 to be fixedly connected to the first surrounding tube 1141 and the first side tube 1121, and also to be fixedly connected to the second surrounding tube 1142 and the second side tube 1122. This improves the connection stability between the surrounding tube assembly 114 and the side tube assembly 112, thereby enhancing the structural strength of the frame 11.

[0052] To further improve the structural strength of the frame 11, the frame 11 of this application also includes a middle cross tube 116 and a rear cross tube 117. The middle cross tube 116 extends substantially along the width direction of the electric two-wheeler 100, and is located between and fixedly connected to the first side tube 1121 and the second side tube 1122 to improve the structural stability between the first side tube 1121 and the second side tube 1122. Viewed from the height direction of the electric two-wheeler 100, the middle cross tube 116 overlaps with the accommodating space 110. The rear cross tube 117 is located at the rear of the rear tube assembly 113, and extends substantially along the width direction of the electric two-wheeler 100. The rear cross tube 117 is located substantially between and fixedly connected to the first rear tube 1131 and the second rear tube 1132, thereby improving the structural stability between the first rear tube 1131 and the second rear tube 1132. The rear horizontal tube 117 is located behind the middle horizontal tube 116 and is basically located above the middle horizontal tube 116.

[0053] Specifically, the middle horizontal tube 116 is located above the power battery 16 to avoid interference between the middle horizontal tube 116 and the power battery 16.

[0054] More specifically, the middle cross tube 116 and the rear cross tube 117 can also be used to secure the saddle assembly 17. The saddle assembly 17 includes a seat bucket 171 (see reference). Figure 8) and seat cushion 172 (refer to) Figure 8 The seat compartment 171 can hold a helmet, charger, etc., and is at least partially located between the center cross tube 116 and the rear cross tube 117, and is connected to both the center cross tube 116 and the rear cross tube 117, so that the seat compartment 171 is located on the frame 11. The seat compartment 171 is also at least partially located between the first rear tube 1131 and the second rear tube 1132. The seat 172 provides support for the rider and passenger, and is rotatably connected to the seat compartment 171, and the seat 172 can be rotated to have an open state and a closed state relative to the seat compartment 171. When the seat 172 is in the closed state, the seat 172 is also connected to the rear cross tube 117 via a seat lock. When the seat 172 is in the open state, the rider can retrieve items from the seat compartment 171. When the seat cushion 172 is connected to the seat cushion lock, the seat cushion 172 can cover the seat bucket 171 to facilitate the driver and passenger to sit; when the seat cushion 172 is separated from the seat cushion lock, the seat cushion 172 can rotate relative to the seat bucket 171 to facilitate the driver or passenger to take items from the seat bucket 171.

[0055] As one implementation, the frame 11 also includes a rear tailpipe 118 connected to the middle of the rear cross tube 117. The body panel 12 includes a mudguard cover 121 for mounting components such as a license plate (see reference). Figure 1 The mudguard cover 121 is installed on the rear tailpipe 118. The electric two-wheeler 100 includes a tail box installed on the rear tailpipe 118. The tail box is an optional component of the electric two-wheeler 100 and can be assembled or disassembled according to actual needs.

[0056] Specifically, a seat bucket connection point 1171 for fixing the saddle assembly 17 is provided at the connection between the rear tailpipe 118 and the rear cross tube 117, and the seat bucket 171 is connected to the rear cross tube 117 through the seat bucket connection point 1171. A rear cover connection point 1181 for fixing the mudguard rear cover 121 is provided at the rear of the rear tailpipe 118, and a box body connection point 1182 for fixing the tail box is also provided on the rear tailpipe 118. Along the length of the electric two-wheeled vehicle 100, the box body connection point 1182 is located between the seat bucket connection point 1171 and the rear cover connection point 1181.

[0057] like Figure 5 and Figure 6 As shown, the electric two-wheeler 100 also includes an electrical component 20, which includes a wiring harness assembly 201. The wiring harness assembly 201 is used to realize the electrical connection between the electrical components of the electric two-wheeler 100. The electrical components of the electric two-wheeler 100 include instruments, lights, horns, and other electrical appliances.

[0058] The power battery 16 of this application can be provided in multiples. The wiring harness assembly 201 includes a battery connector 2011 and an adapter connector 2012, with the adapter connector 2012 and the battery connector 2011 at least partially located inside the receiving space 110. The electric two-wheeler 100 also includes electrical components. The battery connector 2011 is electrically connected to the electrical components and drive assembly 15 of the electric two-wheeler 100, one end of the adapter connector 2012 is electrically connected to the battery connector 2011, and the end of the adapter connector 2012 away from the battery connector 2011 is electrically connected to multiple power batteries 16, so that multiple power batteries 16 can simultaneously power the electrical components and drive assembly 15 of the electric two-wheeler 100. With the above configuration, multiple power batteries 16 can be connected via a single adapter 2012 electrically connected to the battery connector 2011. This reduces the number of additional battery connectors 2011, as well as the wiring harnesses between the battery connector 2011 and electrical components, and between the battery connector 2011 and the drive assembly 15. This improves the structural compactness of the electrical assembly 20 and simplifies its structure. Furthermore, the adapter 2012 is easier to replace than the battery connector 2011, thereby improving the maintainability of the electrical assembly 20.

[0059] Specifically, the adapter 2012 and the middle horizontal tube 116 are fixedly connected. Optionally, the middle horizontal tube 116 is provided with cable ties, and the adapter 2012 can be fixed to the middle horizontal tube 116 by the cable ties, thereby improving the stability of the adapter 2012.

[0060] More specifically, the end of the adapter 2012 away from the battery connector 2011 can be connected to at least two wiring harnesses with connectors, each wiring harness being electrically connected to a power battery 16 via a connector. The end of the battery connector 2011 away from the adapter 2012 can also be connected to multiple wiring harnesses, enabling the battery connector 2011 to connect to the electrical components of the electric two-wheeler 100.

[0061] like Figure 2 , Figure 6 and Figure 7 As shown, in one implementation, the battery mounting assembly 18 also includes a battery mounting plate 182 and a roller 183. Specifically, the battery mounting plate 182 is located in front of the central cross tube 116, and its two ends are connected to the first side tube 1121 and the second side tube 1122 respectively, so that the battery mounting plate 182 is fixedly connected to the frame 11. The roller 183 is mounted below the battery mounting plate 182, and the roller 183 is rotatably connected to the battery mounting plate 182. The axis of rotation of the roller 183 extends substantially along the width direction of the electric two-wheeled vehicle 100, and the roller 183 has a guiding function for the power battery 16.

[0062] During the assembly of the power battery 16, the roller 183 can rotate relative to the power battery 16 and abut against the power battery 16, allowing the power battery 16 to enter the receiving space 110 through the guidance of the roller 183. After the power battery 16 is assembled, the abutment between the roller 183 and the power battery 16 can fix the power battery 16 to the battery mounting plate 182.

[0063] It should be noted that, viewed from the height of the electric two-wheeler 100, the storage space 110 is at least partially located behind the battery mounting plate 182.

[0064] Optionally, the body panel 12 also includes a footrest support plate 122, which is connected to the frame 11 and supports the rider's feet. Specifically, the footrest support plate 122 is located between the first side tube 1121 and the second side tube 1122 and is detachably connected to both, facilitating its installation and removal. The footrest support plate 122 is connected to the first and second side tubes 1121 by bolts or similar means. The battery mounting assembly 18 includes a battery pressure plate 184, which is located below and connected to the footrest support plate 122. Since the footrest support plate 122 is connected to the frame 11, the battery pressure plate 184 can be connected to the frame 11 via the footrest support plate 122, allowing the battery pressure plate 184 to be supported by the frame 11. With the above setup, the battery pressure plate 184 can be disassembled and installed at the same time as the foot support plate 122, thereby improving the assembly efficiency of the electric two-wheeler 100.

[0065] The battery pressure plate 184 is located in front of the battery mounting plate 182, and the foot support plate 122 is also located in front of the battery mounting plate 182. After the power battery 16 is assembled via the battery mounting plate 182 and the roller 183, the foot support plate 122 and the battery pressure plate 184 are simultaneously fixedly connected to the frame 11. At this time, the battery pressure plate 184 can cooperate with the battery mounting plate 182 to further secure the power battery 16.

[0066] Specifically, an elastic element 1841 is provided below the battery pressure plate 184. When the power battery 16 is in the installation state, the battery pressure plate 184 covers the top of the power battery 16 so that the battery pressure plate 184 can basically cover the accommodating space 110. The elastic element 1841 abuts against the top of the power battery 16, and the elastic element 1841 can provide a pre-tightening force between the power battery 16 and the battery pressure plate 184 to keep them apart, thereby allowing the battery pressure plate 184 to fix the position of the power battery 16 through the elastic element 1841. The elastic element 1841 can be an elastic component such as a rubber pad or rubber block.

[0067] like Figure 7 As shown, to improve the anti-theft capability of the power battery 16, as one implementation, the vehicle body panel 12 also includes a pressure plate mounting part 123, which is fixedly connected to the frame 11. The electric two-wheeler 100 also includes a locking assembly 19, which is used for unlocking and locking the battery pressure plate 184. The locking assembly 19 includes a battery lock 191, which is located on and connected to the battery mounting plate 182. The pressure plate mounting part 123 can engage with the battery pressure plate 184, and the battery lock 191 locks the battery pressure plate 184 and the battery mounting plate 182 together to prevent others from opening the battery pressure plate 184 and stealing the power battery 16. It should be noted that the battery pressure plate 184 and the battery mounting plate 182 are detachably connected via the battery lock 191, meaning the battery lock 191 can control the locking or unlocking of the battery pressure plate 184 and the battery mounting plate 182. It should be noted that the battery lock 191 can also be fixed to other parts of the electric two-wheeler 100, so that the battery lock 191 is directly or indirectly fixed to the frame 11, and when the battery lock 191 is directly or indirectly fixed to the frame 11, the battery lock 191 can lock the battery pressure plate 184.

[0068] Specifically, the pressure plate mounting part 123 is substantially located on the side tube assembly 112 and is fixedly connected to the side tube assembly 112. When the pressure plate mounting part 123 is in the installed state, viewed from the height direction of the electric two-wheeled vehicle 100, the pressure plate mounting part 123 and the pedal support plate 122 at least partially overlap, so that the pedal support plate 122 can be installed at the same point on the frame 11 as the pressure plate mounting part 123. The power supply installation position of the pressure plate mounting part 123 and the pedal support plate 122 is the overlapping part of the pressure plate mounting part 123 and the pedal support plate 122; the pedal support plate 122 and the pressure plate mounting part 123 are connected to the frame 11 by bolts.

[0069] More specifically, the pressure plate mounting part 123 is also provided with a snap-fit ​​groove 1231, and one end of the battery pressure plate 184 is provided with a snap-fit ​​connector 1842. When the battery pressure plate 184 and the pressure plate mounting part 123 are in a connected state, the snap-fit ​​connector 1842 snaps into the snap-fit ​​groove 1231.

[0070] In this embodiment, the battery lock 191 is located on the side of the battery pressure plate 184 away from the card connector 1842 and is connected to the battery pressure plate 184, so that both sides of the battery pressure plate 184 can be locked by the battery lock 191 and fixed by the pressure plate mounting part 123, thereby improving the anti-theft performance of the electric two-wheeled vehicle 100.

[0071] For example Figure 7 and Figure 8As shown, specifically, the locking assembly 19 also includes an unlocking member 192. The unlocking member 192 is supported by the frame 11 and is kinetically connected to the battery lock 191, so that the unlocking member 192 can be used to control the battery lock 191, thereby unlocking the battery pressure plate 184.

[0072] With the above settings, when it is necessary to remove the power battery 16, the battery lock 191 can be unlocked simply by unlocking the unlocking component 192, thereby improving the ease of unlocking the battery lock 184.

[0073] Specifically, the unlocking component 192 includes an unlocking end 1921 and a pull cable, which is connected to the unlocking end 1921 and the battery lock 191. The unlocking end 1921 is used to unlock the battery lock 191. More specifically, the operator can pull the pull cable through the unlocking end 1921 to separate the battery lock 191 from the battery pressure plate 184, thereby enabling the battery lock 191 to unlock the battery pressure plate 184. The unlocking end 1921 can be a pull ring.

[0074] To make the unlocking component 192 less noticeable, thereby further improving the anti-theft capability of the power battery 16, the vehicle body cover 12 of this application includes a protective component 124 fixedly connected to the frame 11. The protective component 124 is substantially located in front of the seat compartment 171 and at least partially covers the seat compartment 171. The protective component 124 and the seat compartment 171 form a substantially enclosed mounting space 120. At least part of the unlocking component 192 is located within the mounting space 120, and the unlocking component 192 is also connected to the protective component 124, thus achieving the fixation and concealment of the unlocking component 192. The unlocking end 1921 is also located within the mounting space 120. Through the above arrangement, the distance between the unlocking component 192 and the battery lock 191 can be shortened, thereby improving the sensitivity of the unlocking component 192, increasing the unlocking efficiency of the battery lock 191, and saving the length of the unlocking component 192, thus reducing the cost of the unlocking component 192.

[0075] like Figure 8 and Figure 9 As shown, the seat bucket 171 includes a storage space 1710 and an opening located above the storage space 1710. When the seat cushion 172 is in the closed state, the seat cushion 172 covers the opening of the seat bucket 171, thereby allowing the storage space 1710 to be substantially closed through the seat cushion 172. When the seat cushion 172 is in the open state, the driver can retrieve items from the storage space 1710 through the opening of the seat bucket 171.

[0076] More specifically, since the space between the seat bucket 171 and the protective member 124 is a substantially sealed cavity, i.e., the installation space 120 is a substantially sealed cavity, in order to allow the unlocking end 1921 to be operated by the driver, the seat bucket 171 of this application has an operation port 1711 communicating with the installation space 120, and the operation port 1711 also communicating with the storage space 1710. The operation port 1711 is configured to allow operation of the unlocking end 1921 through the storage space 1710. For example, the operation port 1711 is positioned facing the unlocking end 1921, so that when the seat cushion 172 is in the open state, the driver can operate the unlocking end 1921 through the operation port 1711 to unlock the battery lock 191 via the unlocking member 192, thereby unlocking the battery pressure plate 184. With the above configuration, the unlocking end 1921 can only be operated when the seat cushion 172 is in the open state, thereby improving the anti-theft capability of the power battery 16.

[0077] For example, the operating port 1711 is located at the front of the seat 171 along the length of the electric two-wheeler 100, and the unlocking member 192 is located between the protective member 124 and the seat 171, thereby making the distance between the unlocking member 192 and the battery lock 191 shorter, thereby further improving the sensitivity of the unlocking member 192, further improving the unlocking efficiency of the battery lock 191, and saving the length of the unlocking member 192 to reduce the cost of the unlocking member 192.

[0078] Optionally, the saddle assembly 17 also includes an unlocking cover 173, which covers the operating port 1711. The unlocking cover 173 is detachably connected to the seat bucket 171, thereby sealing the operating port 1711 to prevent objects in the seat bucket 171 from accidentally triggering the unlocking member 192 through the operating port 1711. This prevents objects in the seat bucket 171 from accidentally unlocking the battery pressure plate 184, thus ensuring that the battery pressure plate 184 remains locked to the battery lock 191. This prevents others from stealing the power battery 16 due to the unlocking of the battery pressure plate 184, thereby improving the anti-theft performance of the power battery 16. Furthermore, the above configuration further makes the operating port 1711 more concealed.

[0079] For example, the bucket seat 171 also includes a card interface 1712 disposed around the operation port 1711, and the unlocking cover plate 173 is provided with a snap-fit ​​portion 1731, which is at least partially located in the card interface 1712 and snap-fitted with the card interface 1712, thereby enabling the unlocking cover plate 173 to be stably connected to the bucket seat 171.

[0080] To facilitate the removal of the unlocking cover plate 173, a notch 1732 is provided on the unlocking cover plate 173, and the notch 1732 is located on the edge of the unlocking cover plate 173.

[0081] As one implementation, at least some of the electrical components 20 are located within the mounting space 120, and the seat bucket 171 also has a maintenance port 1713. The maintenance port 1713 connects the mounting space 120 and the storage space 1710, and is configured to allow maintenance of the electrical components 20 located within the mounting space 120. This configuration allows at least some of the electrical components 20 to be maintained or operated through the maintenance port 1713, avoiding the need to disassemble a large number of body panels 12, thereby improving the maintenance efficiency of the electric two-wheeler 100.

[0082] The saddle assembly 17 also includes a service plate 174 covering the service port 1713, which is detachably connected to the seat bucket 171.

[0083] Electrical components 20 include a remote upgrade module 202, an on-board diagnostic module 203, and / or a fuse box 204. The remote upgrade module 202, the on-board diagnostic module 203, and the fuse box 204 can all be fixed to at least one of the frame 11, the seat 171, and the protective element 124.

[0084] The maintenance port 1713 is configured to face at least one of the remote upgrade module 202, the on-board diagnostic module 203, and the fuse box 204. This configuration allows at least one of the remote upgrade module 202, the on-board diagnostic module 203, and the fuse box 204 to be repaired or operated through the maintenance port 1713, thus avoiding the need to disassemble numerous body panels 12 and improving the maintenance efficiency of the electric two-wheeler 100.

[0085] In this application, the service port 1713 connects to the installation space 120, and at least one of the remote upgrade module 202, the on-board diagnostic module 203, and the fuse box 204 is located within the installation space 120, thereby enabling maintenance personnel to perform maintenance on at least one of the remote upgrade module 202, the on-board diagnostic module 203, and the fuse box 204 within the installation space 120 through the service port 1713.

[0086] Specifically, the seat 171 includes a first sidewall 1714 and a second sidewall 1715, which do not overlap. A maintenance port 1713 is located on the first sidewall 1714, and an operation port 1711 is located on the second sidewall 1715. This arrangement allows the maintenance port 1713 and the operation port 1711 to operate independently, thus ensuring their normal operation.

[0087] The second sidewall 1715 is provided with a connecting part 1715a, and the maintenance plate 174 is connected to the connecting part 1715a.

[0088] For example, the connecting part 1715a is provided with a card interface 1715b, and the maintenance plate 174 is provided with a buckle. The maintenance plate 174 is engaged with the card interface 1715b by the buckle.

[0089] For example, a plug-in interface 1714a is provided on the first sidewall 1714, and the end of the maintenance port 1713 away from the connecting part 1715a is defined as the plug-in end. The plug-in interface 1714a is located near the plug-in end, and the maintenance plate 174 is plugged into the plug-in interface 1714a.

[0090] With the above settings, the repair board 174 can be plugged into the insertion interface 1714a and then snapped into the card interface 1715b, thereby realizing the installation of the repair board 174; and during the disassembly of the repair board 174, the snap-on can be removed from the card interface 1715b to complete the disassembly of the repair board 174.

[0091] In this application, the first sidewall 1714 and the second sidewall 1715 can be arranged perpendicularly to each other. This arrangement allows the installation and removal direction of the maintenance plate 174 to be substantially perpendicular to the orientation of the maintenance port 1713, thereby facilitating the arrangement of the maintenance port 1713 while meeting the volume requirements of the tub 171, resulting in a more compact structure for the tub 171. Furthermore, the perpendicularity of the installation and removal direction of the maintenance plate 174 to the orientation of the maintenance port 1713 also facilitates operation by maintenance personnel, thereby improving the human-machine interface of the maintenance port 1713.

[0092] As an optional implementation, the first sidewall 1714 is substantially perpendicular to the length direction of the electric two-wheeler 100, and the second sidewall 1715 is substantially perpendicular to the height direction of the electric two-wheeler 100. With this arrangement, when viewed along the length direction of the electric two-wheeler 100, at least one of the remote upgrade module 202, the on-board diagnostic module 203, and the fuse box 204 can at least partially overlap with the maintenance port 1713, thereby facilitating maintenance of the remote upgrade module 202, the on-board diagnostic module 203, and / or the fuse box 204 by the operator through the maintenance port 1713. Furthermore, with this arrangement, when viewed along the height direction of the electric two-wheeler 100, the operating port 1711 can at least partially overlap with the unlocking end 1921, thereby facilitating the driver to control the unlocking component 192 to unlock the battery lock 191 through the operating port 1711, thus improving the unlocking efficiency of the battery pressure plate 184.

[0093] like Figure 10 and Figure 11 As shown, as one implementation, the electric two-wheeler 100 also includes a charging system 21 (see reference). Figure 8 The charging system 21 is electrically connected to the power battery 16 to charge the power battery 16.

[0094] Specifically, the charging system 21 includes a charging bracket 211, a charging connector 212, and a charging control module 213. The charging bracket 211 is located on and connected to the protective member 124, and is at least partially located between the protective member 124 and the seat 171, and is at least partially located outside the mounting space 120. The charging bracket 211 is positioned in front of the seat 171. The charging connector 212 is used to connect to an external power source, thereby enabling the charging connector 212 to charge the power battery 16. The charging connector 212 is located on the charging bracket 211, and faces away from the mounting space 120, thus ensuring that the charging connector 212 is at least partially located outside the mounting space 120, facilitating connection to an external power source. The charging control module 213 is located in the installation space 120. The charging control module 213 is electrically connected to the charging connector 212 and the power battery 16. The charging control module 213 is used to control the external voltage input from the charging connector 212 so that the external voltage can be adapted to the power battery 16.

[0095] In this embodiment, the charging control module 213 is fixedly connected to the charging bracket 211, thereby enabling the charging control module 213 to be fixed to the charging bracket 211. This prevents the charging control module 213 from being damaged due to shaking during the operation of the electric two-wheeled vehicle 100, thus improving the service life of the charging control module 213.

[0096] Optionally, the charging bracket 211 extends downward at least partially to form a fixing structure 2111, and the charging control module 213 is also fixedly connected to the fixing structure 2111, so that the charging control module 213 can be fixed to the charging bracket 211, thereby preventing the charging control module 213 from shaking.

[0097] Optionally, the charging bracket 211 also includes a snap-fit ​​block 2112, which snaps into the fixing structure 2111. The snap-fit ​​block 2112 also snaps into the charging control module 213, thereby enabling an indirect connection between the charging bracket 211 and the charging control module 213 through the snap-fit ​​block 2112.

[0098] Specifically, the card block 2112 has a first card interface 2112a and a second card interface 2112b. The fixing structure 2111 is basically a snap-fit ​​structure. The charging control module 213 has a card connection structure 2131. The fixing structure 2111 is snapped into the first card interface 2112a, and the card connection structure 2131 is snapped into the second card interface 2112b.

[0099] It should be noted that the connection between the fixing structure 2111 and the charging control module 213 can also be by bonding, cable tie connection, etc. As long as the connection between the fixing structure 2111 and the charging control module 213 is achieved, this application does not impose any restrictions.

[0100] For example, the latching block 2112 is made of a flexible material. For instance, the latching block 2112 can be a rubber block, etc., so that the latching block 2112 can absorb the vibration of the electric two-wheeler 100 during driving, thereby further improving the stability of the charging control module 213.

[0101] In this application, the charging bracket 211 has a receiving groove 2114, a through hole 2115, and multiple connecting holes 2116. The through hole 2115 is located at the bottom of the receiving groove 2114, and the multiple connecting holes 2116 are arranged around the through hole 2115. The charging connector 212 is located in the receiving groove 2114 and is connected to the connecting holes 2116 by fasteners. The charging connector 212 also at least partially passes through the through hole 2115, and the portion of the charging connector 212 passing through the through hole 2115 is also electrically connected to the charging control module 213. Through the above arrangement, the charging connector 212 can be embedded in the charging bracket 211, thereby improving the protection of the charging connector 212. At the same time, the front surface of the charging bracket 211, the front surface of the charging connector 212, and the front surface of the protective member 124 can be made substantially flush, thereby improving the surface flatness of the electric two-wheeled vehicle 100.

[0102] In one implementation, the charging bracket 211 includes multiple fixing parts 2113, which are integrally formed with the charging bracket 211. The multiple fixing parts 2113 and the protective member 124 are connected by fasteners. Optionally, the fixing parts 2113 are connected to the inner side of the protective member 124, that is, the fixing parts 2113 can be connected to the rear side of the protective member 124, so that the connection point between the charging bracket 211 and the protective member 124 is located in the installation space 120, thereby improving the protection of the connection point between the charging bracket 211 and the protective member 124.

[0103] Specifically, the electrical component 20 includes a charging harness 206 and a fixing strap 207 sleeved on the charging harness 206. The fixing strap 207 can be a cable tie with a snap-fit ​​connector. The charging harness 206 is used for connection between the power battery 16 and the charging control module 213. One end of the charging harness 206 is electrically connected to the charging control module 213, and the end of the charging harness 206 away from the charging control module 213 is electrically connected to the power battery 16. At least one fixing part 2113 has a first harness fixing hole 2113a, and the fixing strap 207 snaps into the first harness fixing hole 2113a, thereby fixing the charging harness 206.

[0104] Specifically, the electrical component 20 also includes a communication harness 208, which has a snap-fit ​​connector 2081. The electrical component 20 also includes a controller 200, which is used to implement electrical control of the electric two-wheeler 100. The communication harness 208 can be used for communication between the charging control module 213 and the controller 200; the controller 200 can be a vehicle control unit (VCU), body control module (BCM), etc. One end of the communication harness 208 is electrically connected to the charging control module 213, and the end of the communication harness 208 away from the charging control module 213 is electrically connected to the controller 200. At least one fixing part 2113 has a second harness fixing hole 2113b, and the communication harness 208 is snapped into the second harness fixing hole 2113b through the snap-fit ​​connector 2081, thereby fixing the communication harness 208.

[0105] With the above settings, the fixing part 2113 can be fixed to different wire harnesses, thereby improving the versatility of the fixing part 2113.

[0106] For example, the first wire harness fixing hole 2113a and the second wire harness fixing hole 2113b are located on the same fixing part 2113, thereby improving the structural compactness of the fixing part 2113 and improving the space utilization of the fixing part 2113.

[0107] like Figure 10 and Figure 11 As shown, in one implementation, the unlocking component 192 is connected to the charging bracket 211 so that the unlocking component 192 can be connected to the protective component 124 through the charging bracket 211. Specifically, the unlocking component 192 is provided with a cable fixing bracket 1922, which is connected to both the unlocking component 192 and the charging bracket 211 to achieve the connection between the unlocking component 192 and the charging bracket 211.

[0108] More specifically, at least one fixing part 2113 has a lock fixing hole 2113c, and the unlocking part 192 is connected to the lock fixing hole 2113c by a fastener so that the unlocking part 192 and the charging bracket 211 are connected.

[0109] It should be noted that all fasteners in this application can be bolts, which will not be described in detail here.

[0110] like Figure 12 and Figure 13 As shown, the seat cushion 172 includes a support frame 1721 and a seat cushion body 1722. The seat cushion body 1722 is located on the support frame 1721 and is fixedly connected to the support frame 1721, and the seat cushion body 1722 is used to support the driver. The support frame 1721 serves as the base of the seat cushion 172 and is connected to the seat bucket 171.

[0111] The electric two-wheeler 100 also includes a sensing component 209, which detects pressure on the seat cushion 172 to determine whether the rider is on the seat cushion 172. Specifically, the support frame 1721 has an arrangement slot 1721a. The arrangement slot 1721a extends through the support frame 1721 along the height direction of the electric two-wheeler 100. The sensing component 209 includes a sensing bracket 2091 and a pressure sensing mechanism 2092. The sensing bracket 2091 is at least partially located in the arrangement slot 1721a. The pressure sensing mechanism 2092 is mounted above and connected to the sensing bracket 2091, and is located between the seat cushion body 1722 and the sensing bracket 2091. The pressure sensing mechanism 2092 also abuts against the seat cushion body 1722 so that it can detect the pressure on the seat cushion body 1722. The pressure sensing mechanism 2092 may be one or more pressure sensors; the pressure sensing mechanism 2092 and the sensing bracket 2091 may be connected by a fixed connection method such as adhesive, which is not limited in this application.

[0112] More specifically, the sensor bracket 2091 includes a first connecting part 2091a and a second connecting part 2091b. The first connecting part 2091a is rotatably connected to the support frame 1721, and the second connecting part 2091b can fix or change the relative position between itself and the support frame 1721. With the above configuration, when the relative position between the second connecting part 2091b and the support frame 1721 is fixed, the sensing bracket 2091 can be fixed to the support frame 1721 through the first connecting part 2091a and the second connecting part 2091b; when the relative position between the second connecting part 2091b and the support frame 1721 changes, the sensing bracket 2091 can be rotated relative to the support frame 1721 through the first connecting part 2091a, so that the pressure sensing mechanism 2092 fixed above the sensing bracket 2091 can rotate with the sensing bracket 2091 to below the support frame 1721, thereby facilitating the maintenance and disassembly of the pressure sensing mechanism 2092, and improving the maintainability and replaceability of the pressure sensing mechanism 2092.

[0113] Specifically, since the second connecting part 2091b can fix or change its relative position with the support frame 1721, the sensor bracket 2091 and the support frame 1721 have both an installed state and a disassembled state. When the sensor bracket 2091 and the support frame 1721 are in the installed state, both the first connecting part 2091a and the second connecting part 2091b are connected to the support frame 1721. When the sensor bracket 2091 and the support frame 1721 are in the disassembled state, only the first connecting part 2091a is connected to the support frame 1721. Through the above arrangement, when the sensor bracket 2091 and the support frame 1721 are in the disassembled state, the sensor bracket 2091 can rotate relative to the support frame 1721, thereby facilitating the maintenance and disassembly of the pressure sensing mechanism 2092, and improving the maintainability and replaceability of the pressure sensing mechanism 2092. Furthermore, when the sensor bracket 2091 and the support frame 1721 are in the installation state, the above-mentioned arrangement can fix the sensor component 209 on the support frame 1721, thereby enabling the sensor component 209 to work normally.

[0114] It should be noted that this application describes the first connecting part 2091a and the second connecting part 2091b as examples where they are located at opposite ends of the sensing bracket 2091. It is understood that the positions of the first connecting part 2091a and the second connecting part 2091b on the sensing bracket 2091 can be arbitrary, and this application will not elaborate further.

[0115] As one implementation, the sensor bracket 2091 also includes a pivot shaft 2091c, which is integrally formed with the first connecting part 2091a. The support frame 1721 has a rotation groove 1721b, and the pivot shaft 2091c is located in the rotation groove 1721b. The pivot shaft 2091c can rotate within the rotation groove 1721b, allowing the sensor bracket 2091 to rotate relative to the rotation groove 1721b around the pivot shaft 2091c. The rotation groove 1721b communicates with the arrangement groove 1721a to reduce the processing difficulty of the rotation groove 1721b. Specifically, there are two rotation grooves 1741b, distributed on both sides of the arrangement groove 1721a. The two ends of the pivot shaft 2091c are respectively located within the two rotation grooves 1741b, and the two ends of the pivot shaft 2091c are rotatably connected to the two rotation grooves 1741b respectively.

[0116] In this embodiment, an opening for mounting the pivot shaft 2091c is also provided above the rotating groove 1721b. The sensing assembly 209 also includes a shaft cover plate 2094, which covers the opening above the rotating groove 1721b and is connected to the support frame 1721, thereby improving the rotational stability of the pivot shaft 2091c in the rotating groove 1721b; at the same time, during the assembly process of the seat body 1722 and the support frame 1721, the position of the pivot shaft 2091c can be limited by the shaft cover plate 2094 to prevent the sensing assembly 209 from shifting during the assembly process, thereby improving the detection accuracy of the pressure sensing mechanism 2092.

[0117] Optionally, the support frame 1721 extends at least partially upward to form a mounting post 1721c, which is located on the side of the rotating groove 1721b away from the arrangement groove 1721a, and the shaft cover plate 2094 is connected to the mounting post 1721c. The mounting post 1721c can be a boss post, facilitating the connection between the shaft cover plate 2094 and the mounting post 1721c using bolts or other fasteners.

[0118] In this embodiment, there are two mounting posts 1721c, and the arrangement groove 1721a is located between the two rotating grooves 1721b. Both rotating grooves 1721b are located between the two mounting posts 1721c.

[0119] As an alternative implementation, the support frame 1721 is provided with multiple mounting parts 1721d, which are arranged around the arrangement groove 1721a. The sensor bracket 2091 is also connected to the mounting parts 1721d by fasteners, thereby improving the connection stability between the sensor bracket 2091 and the support frame 1721.

[0120] Specifically, the mounting part 1721d has a nut embedded inside, and the fastener passes through the sensor bracket 2091 and is fixedly connected to the nut.

[0121] It should be noted that the lower side of the mounting part 1721d may have a through hole or a threaded hole. The fastener passes through the support frame 1721, the through hole or the threaded hole from bottom to top and connects with the nut inside the mounting part 1721d, thereby realizing the connection between the support frame 1721 and the sensor bracket 2091. If the lower side of the mounting part 1721d has a threaded hole, the mounting part 1721d does not need to have a nut embedded inside; the connection between the support frame 1721 and the sensor bracket 2091 can be achieved solely through the cooperation of the fastener and the threaded hole. This application does not impose any restrictions on this.

[0122] It should be noted that all fasteners in this embodiment can be bolts.

[0123] As one implementation, the sensing assembly 209 also includes a sensing harness 2095, which is electrically connected to the pressure sensing mechanism 2092. Specifically, the extension direction of the pressure sensing mechanism 2092 is substantially the same as the extension direction of the sensing bracket 2091. The extension direction of the sensing bracket 2091 is defined as from the first connecting portion 2091a to the second connecting portion 2091b. The pressure sensing mechanism 2092 includes a connecting end located at the second connecting portion 2091b. The sensing harness 2095 is connected to the connecting end of the pressure sensing mechanism 2092, and the sensing harness 2095 is positioned close to the second connecting portion 2091b to avoid interference between the sensing harness 2095 and the pivot shaft 2091c located at the first connecting portion 2091a, and to avoid interference between the sensing harness 2095 and the shaft cover plate 2094.

[0124] Specifically, since the pressure sensing mechanism 2092 transmits the pressure signal to the controller of the electric two-wheeler 100 through the sensing harness 2095, the end of the sensing harness 2095 away from the connection end of the pressure sensing mechanism 2092 is also connected to the controller of the electric two-wheeler 100. The controller of the electric two-wheeler 100 can be a vehicle control unit (VCU), a body control module (BCM), etc. In this application, the sensing harness 2095 can extend forward of the seat bucket 171 to facilitate connection between the sensing harness 2095 and the controller of the electric two-wheeler 100. Therefore, the connection point between the pressure sensing mechanism 2092 and the sensing harness 2095 is located at the front of the sensing bracket 2091, that is, the second connection part 2091b is located in front of the first connection part 2091a. This helps to shorten the length of the sensing harness 2095, simplifying the structure of the sensing component 209 and saving materials for the sensing component 209.

[0125] In this embodiment, a wire groove 1721e is also provided at the lower part of the support frame 1721. The sensing wire harness 2095 can pass through the arrangement groove 1721a and is at least partially located in the wire groove 1721e. The sensing wire harness 2095 is also engaged with the wire groove 1721e, which facilitates the arrangement of the sensing wire harness 2095 on the support frame 1721 and is beneficial to the wiring layout of the sensing wire harness 2095.

[0126] 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 protection scope of the appended claims.
