The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0025] like Figure 1 and Figure 2 As shown, this application provides an electric two-wheeled vehicle 100, which includes a frame 10, a body panel 20, a running gear 30, a suspension system 40, a power system 50, and a lighting system 60.

[0026] The body panel 20 at least partially covers the frame 10. The running gear 30 is at least partially disposed under the frame 10, and includes front wheels 31 and rear wheels 32. A suspension system 40 connects the front wheels 31 and rear wheels 32 to the frame 10. A power system 50 is supported by the frame 10, connected to the running gear 30, and used to drive the running gear 30. For example, the power system 50 drives the rear wheels 32 to rotate.

[0027] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 and Figure 2 The directions shown are front, back, left, right, up, and down. In this embodiment, the front, back, left, right, up, and down directions refer to the directions when the electric two-wheeled vehicle 100 is on a horizontal plane. The front-back direction refers to the length direction of the electric two-wheeled vehicle 100 provided in this application. The left-right direction refers to the width direction of the electric two-wheeled vehicle 100 provided in this application. The up-down direction refers to the height direction of the electric two-wheeled vehicle 100 provided in this application.

[0028] As one implementation method, such as Figure 2As shown, the frame 10 includes a front frame 11, a middle frame 12, and a rear frame 13 connected sequentially along the front-rear direction of the electric two-wheeler 100. Viewed along the length of the electric two-wheeler 100, the frame 10 is substantially symmetrical about its central axis.

[0029] Please see Figure 2 In some embodiments, the front frame 11 includes a head tube 111 and a main tube 112, with the main tube 112 connected to the middle of the head tube 111. The head tube 111 is located above the front wheel 31, which is connected to the head tube 111 via a suspension system 40. Specifically, the suspension system 40 includes a front shock absorber 41, through which the front wheel 31 is connected to the head tube 111.

[0030] Please see Figure 2 In some embodiments, the mid-frame 12 includes a pair of longitudinal beams 121 extending along the front-rear direction of the electric two-wheeler 100 and a crossbeam 122 extending along the width direction of the electric two-wheeler 100 and connecting the two longitudinal beams 121. Exemplarily, the two longitudinal beams 121 are disposed on the left and right sides of the electric two-wheeler 100, with one end of each beam connected to the left and right sides of the lower part of the front frame 11, and the other end connected to the rear frame 13. The longitudinal beams 121 and the crossbeam 122 enclose an accommodating space 123. Specifically, the power system 50 includes a battery assembly 51, which is disposed within the accommodating space 123.

[0031] Please see Figure 2 In some embodiments, the mid-frame 12 includes a pair of sub-beams 124 extending along the front-rear direction of the electric two-wheeler 100. The two sub-beams 124 are disposed on the left and right sides of the electric two-wheeler 100 and below the longitudinal beam 121. One end of the sub-beam 124 is connected to the bottom of the main beam 112, and the other end of the sub-beam 124 is connected to the rear frame 13.

[0032] Please see Figure 3 , Figure 4 and Figure 5 As one implementation, the front frame 11 also includes a handlebar 113, which is connected to the upper end of the head tube 111. The body panel 20 includes a front panel 21 located in front of the head tube 111, a rear protective plate 22 located behind the head tube 111, and a center mounting plate 23. The front frame 11, the front panel 21, the rear protective plate 22, and the center mounting plate 23 all belong to the front of the electric two-wheeled vehicle 100.

[0033] In some embodiments, a front panel 21 is disposed on the front side of the electric two-wheeler 100, a rear protective plate 22 is disposed on the rear side of the front panel 21, and a middle mounting plate 23 is disposed between the front panel 21 and the rear protective plate 22; the front panel 21 and the middle mounting plate 23 are detachably connected, forming a mounting space 24 between the front panel 21 and the middle mounting plate 23. The electric two-wheeler 100 also includes an electrical assembly 70, which is electrically connected to a battery assembly 51; the electrical assembly 70 includes a plurality of electrical components 71, which are detachably disposed on the middle mounting plate 23 and located in the mounting space 24.

[0034] By providing an intermediate mounting plate 23 between the front panel 21 and the rear protective plate 22, an installation position for the electrical component 70 is provided. Furthermore, the front panel 21 covers the electrical component 70 within the installation space 24, providing protection. When maintenance of the electrical component 70 is required, simply removing the front panel 21 exposes the component, facilitating repair. By centrally mounting multiple electrical components 71 on the intermediate mounting plate 23, simultaneous maintenance of multiple components 71 is possible, improving both repair efficiency and convenience.

[0035] Please see Figure 1 and Figure 3 In some embodiments, the frame 10 also includes a seat bucket 14, which is disposed on the rear side of the middle frame 12 and the rear frame 13. The middle frame 12, the rear guard plate 22, the seat bucket 14, and the rear guard plate 22 form a seating space where the driver's legs can be placed, and the rear guard plate 22 can provide protection for the driver's legs.

[0036] Please see Figure 5 and Figure 6 In some embodiments, the electrical assembly 70 includes connecting wires 72, through which multiple electrical components 71 are electrically connected. The connecting wires 72 are disposed on an intermediate mounting plate 23. Understandably, multiple connecting wires 72 are provided. By uniformly disposing of the electrical components 71 and connecting wires 72 on the intermediate mounting plate 23, centralized wiring is achieved, avoiding the clutter caused by traditional distributed wiring. The mounting plate, as a mounting carrier, can fix the routing of the connecting wires 72, reducing cross-tangle.

[0037] Please see Figure 5 and Figure 6 In some embodiments, multiple electrical components 71 include a voltage converter 711 (DC / DC converter), an in-vehicle remote communication terminal 712 (T-box), and a wiring harness connector 713, which connects the connection lines 72 between the different electrical components 71.

[0038] When different electrical components 71, such as the voltage converter 711, the vehicle-mounted remote communication terminal 712, and the wiring harness connector 713, are damaged, they can all be repaired by disassembling the front panel 21, improving the convenience of repairing different electrical components 71. By connecting the connecting wires 72 of different electrical components 71 through the wiring harness connector 713, the assembly between the connecting wires 72 is simplified, enabling plug-and-play replacement and reducing the cost of rewiring during maintenance. For example, when the voltage converter 711 fails, the wiring harness connector 713 can be quickly disconnected and replaced.

[0039] Please see Figure 5 and Figure 6 In some embodiments, the voltage converter 711 is used to transform the input voltage and effectively output a fixed voltage. For example, the voltage converter 711 includes a large DC 7111 (high-power DC-DC converter), which is used to convert high-voltage DC to low-voltage DC to provide a stable low-voltage power supply for specific high-power low-voltage devices (such as ABS modules, sensors, etc.). Another example is that the voltage converter 711 includes a small DC 7112 (low-power DC-DC converter or auxiliary power module), which is used to power low-voltage electrical appliances such as lights, instruments, and horns. It is the core of the vehicle's low-voltage system and can replace some of the functions of the large DC 7111 when power requirements are low.

[0040] In some embodiments, the vehicle-mounted remote communication terminal 712 has network connectivity, such as enabling vehicle positioning, remote unlocking, and status monitoring (e.g., battery level, fault codes) via 4G / 5G or GPS. The vehicle-mounted remote communication terminal 712 also has data interaction capabilities, such as uploading riding data to the cloud and supporting applications to view historical tracks, battery health, etc.

[0041] Please see Figure 5 and Figure 6 In some embodiments, the intermediate mounting plate 23 includes a resilient slot 231 to which the wire harness connector 713 is detachably mounted. For example, the resilient slot 231 has an opening that can be expanded by elastic deformation, allowing the wire harness connector 713 to enter the resilient slot 231. After the wire harness connector 713 enters the resilient slot 231, the resilient slot 231 returns to its original shape to prevent the wire harness connector 713 from disengaging from the resilient slot 231.

[0042] By detachably installing the wire harness connector 713 into the elastic slot 231, the wire harness connector 713 can be fixed, and it is also convenient to disassemble and replace the wire harness connector 713, and to adjust the position of the wire harness connector 713 according to actual needs.

[0043] Understandably, the flexible slot 231 can be integrally molded onto the intermediate mounting plate 23, or detachably mounted onto the intermediate mounting plate 23 by means of screws, adhesives, etc.

[0044] Please see Figure 5 and Figure 6 In some embodiments, the electrical assembly 70 includes an electrical connector 73 that detachably connects the electrical element 71 to the intermediate mounting plate 23. For example, the electrical connector 73 may be a bolt, self-tapping screw, or similar component. Understandably, a single electrical element 71 is secured by multiple electrical connectors 73.

[0045] Electrical component 71 can be quickly installed or removed via electrical connector 73 without welding or complex fixing, reducing assembly difficulty and improving production line efficiency. In case of a single electrical component 71 failure, it can be disassembled and replaced individually, avoiding complete disassembly.

[0046] Please see Figure 5 and Figure 6 In some embodiments, the front panel 21 includes a resilient snap fastener 211, and the middle mounting plate 23 includes a mounting hole 232, with the resilient snap fastener 211 detachably connected to the mounting hole 232. Specifically, the resilient snap fastener 211 can reduce its volume through elastic deformation to enter the mounting hole 232 and is interference-fitted with the mounting hole 232. Understandably, multiple resilient snap fasteners and mounting holes 232 can be provided.

[0047] The front panel 21 can be detachably engaged with the mounting hole 232 by the elastic deformation of the elastic buckle 211, thereby facilitating the assembly and disassembly of the front panel 21 and the middle mounting plate 23.

[0048] In some embodiments, the edge of the front panel 21 is also fixed to the rear protective plate 22 by a plurality of screws, further improving the installation stability of the front panel 21.

[0049] Please see Figure 3 , Figure 4 and Figure 5 In some embodiments, the main tube 112 connects the head tube 111 to the front side of the mid-frame 12, with the head tube 111 and the main tube 112 located between the intermediate mounting plate 23 and the rear protective plate 22. The rear protective plate 22 and the intermediate mounting plate 23 can clamp and cover the main tube 112 and the head tube 111 of the front frame 11, thereby improving the appearance of the front frame 11 and making the front part of the electric two-wheeler 100 more compact. The head tube 111 and the main tube 112 can provide support for the rear protective plate 22 and the intermediate mounting plate 23, thereby improving the structural strength of the front part.

[0050] Please see Figure 2 and Figure 3In some embodiments, the front frame 11 includes a mounting bracket 114 disposed on the front side of the head tube 111, and an intermediate mounting plate 23 connected to the mounting bracket 114. For example, the intermediate mounting plate 23 is mounted to the mounting bracket 114 by bolts and nuts; or, for another example, the intermediate mounting plate 23 is provided with a through hole, and the mounting bracket 114 extends into the mounting space 24 through the through hole to connect the intermediate mounting plate 23 and restrict the relative position of the intermediate mounting plate 23 and the mounting bracket 114.

[0051] The mounting bracket 114 provides a mounting base for the intermediate mounting plate 23 and supports the intermediate mounting plate 23, so that a certain gap can be maintained between the intermediate mounting plate 23 and the rear protective plate 22. This is beneficial for placing the head tube 111 in the gap between the intermediate mounting plate 23 and the rear protective plate 22, and also gives the intermediate mounting plate 23 a certain deformation space, reducing the risk of squeezing the rear protective plate 22.

[0052] In some embodiments, the mounting bracket 114 is a sheet metal part, thereby ensuring the support strength of the mounting bracket 114 for the intermediate mounting plate 23.

[0053] In some embodiments, the mounting bracket 114 is welded to the head tube 111. Alternatively, the mounting bracket 114 is fixed to the head tube 111 by bolts.

[0054] In some embodiments, the front panel 21, the middle mounting plate 23, and the rear protective plate 22 are all made of plastic, which reduces the use of sheet metal parts and helps to reduce the overall vehicle weight.

[0055] Please see Figure 4 and Figure 5 In some embodiments, the lighting system 60 includes a headlight 62 and a taillight 61. The headlight 62 is disposed on a central mounting plate 23, and the front panel 21 includes a light-transmitting hole 212 through which the headlight 62 is exposed. Exemplarily, the headlight 62 is located below the electrical component 70 to avoid obstructing the electrical component 70.

[0056] Integrating the headlight 62 into the center mounting plate 23 further improves the compactness of the assembly of components at the front of the vehicle and reduces space occupation. The setting of the light-transmitting hole 212 allows the headlight 62 to be exposed, and the center mounting plate 23 and the front panel 21 can provide protection for the headlight 62.

[0057] In addition, those skilled in the art may make other changes within this application. Of course, all such changes made in accordance with this application should be included within the scope disclosed in this application.
