[0066] Optionally, in the orthographic projection in the second direction, the shape of the fifth heat conductive sheet 25 may be circular, rectangular, non-circular, etc., without limitation. Optionally, the shape of the sixth heat conductive sheet 26 is similar to that of the fifth heat conductive sheet 25, which can be used for reference only and will not be described in detail.

[0068] Please refer to Figure 2 and Figure 3 The heat conducting component 20 is an elastic component, and the heat conducting component 20 is used to undergo elastic deformation to absorb vibration. Optionally, the heat conducting component 20 can be made of a material with elasticity, good thermal conductivity and stable chemical properties, specifically silicone, silicone grease and graphite, etc., without limitation.

[0069] By setting the heat-conducting component 20 as an elastic component, when the two-wheeled electric vehicle generates vibration during driving, the heat-conducting component 20 can be elastically deformed under the compression between the battery 200 and the frame 10, and the vibration between the battery 200 and the frame 10 can be easily absorbed, thereby preventing the battery 200 from colliding with the frame 10 and avoiding damage to the battery 200.

[0070] Please refer to Figure 1 and Figure 4 The utility model also provides a two-wheeled electric vehicle, comprising a frame 10, a battery 200 and a heat-conducting component 20. The frame 10 encloses an installation space 11, and the frame 10 is a heat-conducting component. The battery 200 is used to be accommodated in the installation space 11. The heat-conducting component 20 is attached to the outer surface of the battery 200, and the heat-conducting component 20 is used to contact the frame 10.

[0071] Optionally, the shell 201 corresponds to the position where the heat-conducting component 20 is attached to the frame 10 of the aforementioned frame assembly 100, and is respectively attached with the aforementioned plurality of first heat-conducting sheets 21, second heat-conducting sheets 22, third heat-conducting sheets 23, fourth heat-conducting sheets 24, fifth heat-conducting sheets 25 and sixth heat-conducting sheets 26.

[0072] The two-wheeled electric vehicle provided by the utility model adopts a frame 10, a battery 200 and a heat-conducting component 20. The frame 10 encloses an installation space 11. The frame 10 is a heat-conducting component. The heat-conducting component 20 is attached to the outer surface of the battery 200. The heat-conducting component 20 is used to contact the frame 10, so that the heat-conducting component 20 can be pre-attached to the outer surface of the battery 200 and installed into the installation space 11 of the frame 10 together with the battery 200, which speeds up the installation speed of the battery 200 and the frame 10. At the same time, the battery 200 can also transfer heat to the frame 10, which enhances the heat dissipation effect of the battery 200, speeds up the heat dissipation speed of the battery 200, and makes it difficult for the battery 200 to overheat and reduce load.
