[0038] Reference Figures 1 to 5 An embodiment of the present utility model provides an electric motorcycle, comprising a main frame 100 and a mounting assembly, the mounting assembly comprising a battery 200, a controller 300, a rear swing arm 400, a motor 500, a shock absorber 600, and a subframe 700. The main frame 100 has an inner cavity 110 extending along the width of the main frame 100. A mounting seat 140 is provided at one end of the main frame 100 along the length of the main frame 100. The mounting seat 140 extends outward and has a plug-in cavity 130. The mounting assembly comprises a battery 200, a controller 300, a rear swing arm 400, a motor 500, a shock absorber 600, and a subframe 700.

[0039] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the battery 200 can enter the inner cavity 110 through the side wall of the main frame 100, facilitating installation of the battery 200 and the main frame 100. By installing the battery 200 in the inner cavity 110, the battery 200 is protected from damage during tipping, bottoming, and collisions of the electric motorcycle, thereby protecting the battery 200 and improving the safety of the motorcycle. The controller 300 is mounted on the bottom outer end of the main frame 100 to facilitate heat dissipation from the controller 300. The shock absorber 600 and subframe 700 are respectively mounted on the top outer end of the main frame 100, facilitating installation of the shock absorber 600 and subframe 700. The subframe 700 is detachably connected to the main frame 100 and can distribute the load on the main frame 100, reducing its burden, enhancing the structural strength and durability of the main frame 100, and improving the overall load-bearing capacity of the electric motorcycle.

[0040] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the motor 500 is installed on the outer end of the mounting seat 140 away from the inner cavity 110. By positioning the motor 500 on the outer end of the main frame 100 away from the inner cavity 110, the motor 500 can bear the torsional force and longitudinal force during the driving of the electric motorcycle, thereby improving the torsional performance of the electric motorcycle and improving the rigidity and stability of the entire vehicle.

[0041] Reference Figures 2 to 4In some embodiments of the present invention, the insertion cavity 130 is located between the motor 500 and the battery 200. One end of the rear swing arm 400 is located within the insertion cavity 130 and is hingedly connected to the insertion cavity 130. This allows the rear swing arm 400 to be located above the motor 500. This prevents the rear swing arm 400 from obstructing installation and removal of the motor 500, facilitating installation and removal of the motor 500. Furthermore, the location of one end of the rear swing arm 400 between the motor 500 and the battery 200 shortens the wheelbase of the electric motorcycle, improves the handling performance of the electric motorcycle, and allows for a more compact design.

[0042] It is understood that by inserting the battery 200 into the inner cavity 110 through the side wall of the main frame 100, the controller 300 is mounted on the bottom outer end of the main frame 100, the shock absorber 600 and the subframe 700 are respectively mounted on the top outer end of the main frame 100, and the motor 500 is mounted on the outer end of the mounting base 140 facing away from the inner cavity 110, so that the installation and maintenance of the various components in the mounting assembly do not affect each other, thereby facilitating the installation and maintenance of the components. Because the main frame 100 is a single piece, the mounting assembly is directly mounted to the main frame 100, and the mounting points of each component in the mounting assembly are integrated into the frame, eliminating the need for installation accessories and, in turn, reducing installation costs. Furthermore, the main frame 100 is a single piece, which centralizes the center of gravity of the main frame 100, and thus the center of gravity of the entire vehicle, improving the vehicle's handling performance.

[0043] As can be appreciated, the main frame 100 is integrally formed through casting. Compared to welding multiple steel pipes, the cast main frame 100 avoids the problems of stress concentration at the weld seams, welding deformation, poor surface quality at the weld seams, and the need for numerous welding fixtures. This improves the strength, manufacturing precision, and surface quality of the main frame 100. This reduces welding fixtures and processes, saving production costs. Furthermore, the casting process allows for secondary use of residual material after processing, reducing resource waste.

[0044] Reference Figure 3 、 Figure 5 and Figure 6 In some embodiments of the present invention, along the width direction of the main frame 100, the two side walls of the main frame 100 are respectively covered with a cover plate 210, and the battery 200 is located between the two cover plates 210 so that the battery 200 is fixed to the inner cavity 110. At the same time, the cover plate 210 can protect the battery 200 and improve the safety performance of the electric motorcycle.

[0045] Reference Figure 5 and Figure 6In some embodiments of the present invention, a plurality of retaining grooves 160 are provided on both outer sidewalls of the main frame 100 along its width. The retaining grooves 160 communicate with the inner cavity 110, and the cover plate 210 is provided with a plurality of retaining hooks 211. The retaining hooks 211 can be inserted into the retaining grooves 160 and abut against the inner sidewalls of the main frame 100 to secure the cover plate 210 to the main frame 100, facilitating installation of the cover plate 210 and the main frame 100 and improving installation convenience. Furthermore, this reduces the number of components required to install the main frame 100 and the cover plate 210.

[0046] It can be understood that in some embodiments of the present invention, a buffer sheet is provided between the battery 200 and the inner cavity 110, and a buffer sheet is provided between the battery 200 and the cover plate 210. The buffer sheet can fill the gap between the battery 200 and the inner cavity 110, as well as the gap between the battery 200 and the cover plate 210, so as to avoid displacement of the battery 200 during driving of the electric motorcycle, and at the same time avoid impact between the battery 200 and the inner cavity 110 and the battery 200 cover plate 210. The buffer sheet can reduce impact and vibration, protect the battery 200 from damage, improve safety, and maintain stability during driving of the electric motorcycle.

[0047] It is understood that the material of the buffer sheet can be rubber, which has good elasticity, cushioning performance and corrosion resistance. It can also be a polymer material, silicone, silicone rubber and other materials. The material of the buffer sheet can be selected according to the actual production application and is not limited in this application.

[0048] Reference Figure 5 and Figure 7 In some embodiments of the present invention, the rear swing arm 400 is provided with a plug-in portion 410, which is plugged into the plug-in cavity 130.

The mounting base 140 is provided with a fixing hole 190, which is connected to the plug-in cavity 130. After the plug-in portion 410 is inserted into the plug-in cavity 130, fasteners are inserted into the positioning hole 420 and the fixing hole 190 to achieve connection between the rear swing arm 400 and the main frame 100.

[0049] Reference Figure 3 In some embodiments of the present invention, the mounting seat 140 includes two mounting pieces 141 , which extend along the length direction of the main frame 100 , and a plug-in cavity 130 is formed between the two mounting pieces 141 , which facilitates the production of the plug-in cavity 130 .

[0050] Reference Figure 2 and Figure 3In some embodiments of the present invention, an electric motorcycle further includes a mounting member 310. A connecting portion 120 is provided on the bottom outer wall of the main frame 100. The controller 300 and the connecting portion 120 are connected via the mounting member 310, thereby securing the controller 300 to the bottom outer end of the main frame 100. Two sets of connecting portions 120 are provided, one on each side of the controller 300. Two sets of mounting members 310 are provided, with the ends of the mounting members 310 being connected to the ends of the connecting portion 120 and the controller 300, respectively, to securely secure the controller 300 to the main frame 100.

[0051] Reference Figures 1 to 3 The subframe 700 includes a first frame 710 and a second frame 720, which are spaced apart along the width of the main frame 100. The shock absorber 600 is located between the first frame 710 and the second frame 720. This makes the space layout of the electric motorcycle more compact, improves space utilization, and helps to maintain the center of gravity of the electric motorcycle.

[0052] Reference Figure 4 and Figure 5 The main frame 100 is provided with a plurality of mounting portions 150, which are located at the top of the main frame 100. The sub-frame 700 is connected to the mounting portions 150 via fasteners, so that the sub-frame 700 can be detachably connected to the main frame 100. Since the sub-frame 700 is detachably connected to the main frame 100, when the sub-frame 700 needs to be replaced or repaired, the sub-frame 700 can be removed alone without replacing the entire frame of the electric motorcycle, thereby facilitating maintenance of the electric motorcycle and saving costs. Similarly, when the main frame 100 needs to be replaced or repaired, the sub-frame 700 does not need to be replaced, thereby facilitating maintenance of the electric motorcycle and saving costs.

[0053] Reference Figure 2 、 Figure 3 and Figure 5 In some embodiments of the present invention, an electric motorcycle further includes a first footrest 800. A first mounting position 170 is provided on both sides of the mounting base 140 along the width direction. The first mounting position 170 is located at one end of the mounting base 140 close to the controller 300, and the first footrest 800 is mounted on the first mounting position 170. By directly mounting the first footrest 800 on the main frame 100, the number of mounting accessories is reduced, making installation and maintenance of the first footrest 800 easier.

[0054] Reference Figure 2 、 Figure 3 and Figure 5In some embodiments of the present invention, an electric motorcycle further includes a second footrest 900.
