[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 The hub structure of an electric vehicle shown includes a hub body 1, which is used to support one of the main bodies of the sightseeing electric vehicle;

[0028] The tungsten carbide metal protective layer 6 is pasted inside the hub body 1 to enhance the solidity of the hub body 1, and an inner support ring 7 is fixedly installed inside the hub body 1, a mounting plate 8 is arranged inside the inner support ring 7, and a spacer ring 9 is fixedly installed outside the mounting plate 8;

[0029] The first offset wheel spoke 13 is arranged on one side of the outside of the mounting plate 8, and is used for offset support of the hub body 1, and a small airflow heat dissipation port 14 is opened on the outside of the first offset wheel spoke 13, and a second offset wheel spoke 15 is fixedly installed on the other side of the outside of the mounting plate 8, and a large airflow heat dissipation port 16 is opened on the outside of the second offset wheel spoke 15. When the hub is running at high speed, the first offset wheel spoke 13 and the second offset wheel spoke 15 rotate alternately like fan blades to form an internal through-structure for air suction and air discharge, so that the wind on both sides flows in from the small airflow heat dissipation port 14 of the first offset wheel spoke 13, and then flows out from the large airflow heat dissipation port 16 of the second offset wheel spoke 15. When the airflow flows out from the large port and enters the small port, the compressed air in the large port expands rapidly to do work externally, thereby reducing its internal energy and lowering its temperature, thereby allowing the hub structure of the electric vehicle to have good heat dissipation capability.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a tire groove 2 is provided on the outside of the wheel hub body 1, and a reinforcing rib 3 is fixedly installed inside the tire groove 2. A reinforced concave rim 5 installed inside the tire groove 2 by means of a fixing bolt 4 can provide good protection for the wheel hub structure of the electric vehicle after the tire is installed. A fixing bolt 4 runs through the inside of the tire groove 2, and one end of the fixing bolt 4 is movably connected with a reinforced concave rim 5. The reinforcing rib 3 and the reinforced concave rim 5 also improve the rigidity of the edge of the wheel hub body 1, so that when the wheel hub body 1 encounters a collision with objects such as pebbles during driving, it also has good resistance to reduce the loss caused by the collision, and to a certain extent, it also extends the service life of the wheel hub structure of the electric vehicle. The tungsten carbide metal protective layer 6 is tightly fitted to the wheel hub body 1, and the material of the tungsten carbide metal protective layer 6 is: tungsten carbide. The tungsten carbide metal protective layer 6 fitted inside the wheel hub body 1 strengthens the solidity of the wheel hub structure of the electric vehicle itself.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a bearing cavity 10 is provided on one side of the mounting plate 8, a bearing hole 11 is opened on the outside of the bearing cavity 10, and a mounting screw hole 12 is provided on one side of the bearing hole 11. The bearing hole 11 and the mounting screw hole 12 on the mounting plate 8 facilitate the combined installation of the wheel hub structure of the electric vehicle and the sightseeing electric vehicle. The number of the first offset wheel spokes 13 is set to six, and the six first offset wheel spokes 13 are distributed in a circular array on the mounting plate 8. Since the first offset wheel spokes 13 and the second offset wheel spokes 15 form an offset support, the offset support can enhance the stability and load-bearing capacity of the support inside the wheel hub body 1 to ensure the safety of the structure.

[0032] Working principle of the utility model: firstly, the wheel hub structure of the electric vehicle is taken out, and the reinforcing concave rim 5 is installed inside the tire groove 2 by means of the fixing bolts 4. The reinforcing concave rim 5 can not only provide good protection for the wheel hub structure of the electric vehicle after the tire is installed, but also the reinforcing ribs 3 and the reinforcing concave rim 5 can improve the rigidity of the edge of the wheel hub body 1, so that when the wheel hub body 1 encounters a collision with objects such as pebbles during driving, it also has good resistance to reduce the loss caused by the collision, and then the tire is installed outside the reinforcing concave rim 5, and then the bearing hole 11 and the The mounting screw holes 12 are aligned with the bearings of the sightseeing electric vehicle for assembly and installation, so that the wheel hub structure of the electric vehicle is assembled on the sightseeing electric vehicle. When the sightseeing electric vehicle is traveling, as the number of people on the sightseeing electric vehicle increases, the gravity that the wheel hub body 1 needs to bear also increases relatively, and the first offset wheel spokes 13 and the second offset wheel spokes 15 are attached to both sides of the mounting plate 8 to support the wheel hub body 1. Since the first offset wheel spokes 13 and the second offset wheel spokes 15 form an offset support, the offset support can enhance the stability and load-bearing capacity of the support inside the wheel hub body 1. The wheel hub structure has good load-bearing capacity, and then the first offset wheel spoke 13 and the second offset wheel spoke 15 rotate like fan blades when the wheel hub is running at high speed, forming a through structure for internal air intake and outlet. In this way, the wind on both sides flows in from the small airflow heat dissipation port 14 of the first offset wheel spoke 13, and then flows out from the large airflow heat dissipation port 16 of the second offset wheel spoke 15. When the airflow flows out from the large port and enters the small port, the compressed air in the large port It expands rapidly to do work externally, reducing its internal energy and lowering its temperature, so that the wheel hub structure of the electric vehicle has good heat dissipation ability, reducing the high temperature generated by the rotation of the wheel hub structure of the electric vehicle during driving, so that the wheel hub structure of the electric vehicle remains stable and the service life of the wheel hub structure of the electric vehicle is extended. Finally, after completing the installation and use of the wheel hub structure of the entire electric vehicle according to the above operations, the device is maintained daily, wherein the material of the tungsten carbide metal protective layer 6 is: tungsten carbide, and the use process of the wheel hub structure of the electric vehicle is completed.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
