[0037] Please refer to the following: Figure 1 and Figure 2 This application provides an electric bicycle including an antenna module 1, a frame body, and a top cover assembly 3. The frame body has a lower tube 21, in which a first groove 211 for accommodating the antenna module 1 is formed. The groove 211 has a fitted shape and is flush with the outside of the lower tube 21, so the lower tube 21 will not bulge due to the installation of the antenna module 1, thus avoiding any impact on the appearance of the frame body. The top cover assembly 3 is used to fix the antenna module 1. In a specific implementation, after fixing the antenna module 1 to the top cover assembly 3, the top cover assembly 3 and the antenna module 1 are integrally disposed in the first groove 211 of the upper tube 22. In this embodiment, by providing a groove for accommodating the antenna module 1 in the lower tube 21 of the electric bicycle, a mounting position for the antenna module 1 is formed, which can meet the requirements of the antenna environment while avoiding affecting the appearance of the electric bicycle.

[0038] In some embodiments, the frame body also has an upper tube 22, and a first groove 211 is located in the lower tube 21 on the side facing the upper tube 22.

[0039] In some embodiments, a second groove 212 is also provided on the frame body, wherein the second groove 212 is located on the opposite side of the first groove 211 in the lower tube 21, the second groove 212 is used to accommodate the power supply device 4, and the power supply device 4 is flush with the outer surface of the lower tube 21 after being installed in the second groove 212, thereby avoiding affecting the appearance of the frame body.

[0040] Please see Figure 3 and Figure 4 In some embodiments, the upper cover assembly 3 includes an upper cover body 31. A positioning post 32 is provided on the side of the upper cover body 31 opposite to the first groove 211, wherein the positioning post 32 is located at the edge of the upper cover body 31. A protrusion 213 is provided on the edge of the groove, and a positioning hole 214 adapted to the positioning post 32 is provided on the protrusion 213. During installation, the positioning post 32 in the upper cover body 31 is inserted into the positioning hole 214 to achieve positioning of the upper cover assembly 3 and the lower tube 21.

[0041] Please refer to the following: Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the positioning post 32 is a hollow positioning post; correspondingly, the bottom wall of the first groove 211 is provided with a mounting hole 215, which is used to set a screw 5; the screw 5 is used to pass through the mounting hole 215 and enter the positioning post 32 to limit the upper cover assembly 3. In this embodiment, a positioning post 32 can be set at each of the four corners of the upper cover body 31; correspondingly, four positioning holes 214 adapted to the positioning post 32 are provided in the protrusion 213; and four mounting holes 215 adapted to the positioning holes 214 are provided on the bottom wall of the first groove 211. After the positioning post 32 in the upper cover body 31 passes through the positioning hole 214, the screw 5 can be set through the mounting hole 215. The screw 5 passes through the mounting hole 215 and is inserted into the positioning post 32 to lock the upper cover assembly 3, thereby fixing the upper cover assembly 3 and ensuring the tightness of the connection between the upper cover assembly 3 and the lower tube 21.

[0042] Please continue reading Figure 3 As an implementation, the diameter of the positioning post 32 gradually decreases in the direction away from the upper cover body 31; that is, the end of the positioning post 32 closer to the upper cover body 31 is thicker, while the other end of the positioning post 32 away from the upper cover body 31 is relatively thinner. Thus, when the positioning post 32 is inserted into the positioning hole 214, it is ensured that the positioning post 32 can make closer contact with the positioning hole 214, thereby playing the role of fixing the upper cover assembly 3.

[0043] As one embodiment, a limiting rib 34 is provided at one end of the positioning post 32 near the upper cover body 31; in this embodiment, the limiting rib 34 is provided to facilitate the tightness of the connection between the positioning post 32 and the positioning hole 214.

[0044] In some embodiments, the upper cover body 31 is further provided with a plurality of buckles 33, which are located on the edge of the upper cover assembly 3 and can be used to engage with the protrusions 213 in the first groove 211 to further fix the upper cover assembly 3. The antenna module 1 is located in the middle of the upper cover body 31, and the buckles 33 can surround the periphery of the antenna module 1, thereby limiting the antenna module 1 and fixing it to the upper cover assembly 3.

[0045] Please see Figure 7 In some embodiments, a sealing structure 217 is provided between the upper cover body 31 and the protrusion 213. For example, the sealing structure 217 can be a layer of foam adhesive. Before the upper cover assembly 3 is placed in the first groove 211, a layer of foam adhesive is pasted on the protrusion 213 of the first groove 211, and then the upper cover assembly 3 with the antenna module 1 fixed is placed in the first groove 211. In this embodiment, the foam adhesive can both stick the upper cover body 31 to fix the upper cover assembly 3 and seal the upper cover assembly 3 with the first groove 211, thereby ensuring the reliability of the antenna module 1.

[0046] Please refer to the following: Figure 4 and Figure 6 In some embodiments, the bottom wall of the first groove 211 is also provided with a wire-pulling hole 216; when various wires of the electric bicycle pass through the lower tube 21 and encounter the positioning post 32 in the upper cover assembly 3 that cannot pass through, a tool can be used to pull the wire through the wire-pulling hole 216 so that the wire can pass through.

[0047] This application embodiment also provides a frame structure for an electric bicycle. The frame structure includes a frame body with a lower tube 21.
