[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0026] An electric vehicle wheel hub exhaust structure provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Embodiment 1

[0027] Combination Figure 1-4As shown, the utility model provides an electric vehicle wheel hub exhaust structure, comprising a wheel mechanism 100, a protection mechanism 200 and an exhaust mechanism 300, wherein the wheel mechanism 100 comprises a wheel hub 110 and an opening 120 opened on the wheel hub 110;

[0028] The protection mechanism 200 includes a plate body 210 connected to the inner wall of the hub 110 and a limiting tube 220 transversely penetrating the plate body 210;

[0029] The exhaust mechanism 300 includes a rotating shaft 310 movably connected to the plate body 210, a tube cover 320 movably connected to the rotating shaft 310, and a pressure needle 330 connected to the tube cover 320. The tube cover 320 is movably sleeved on the outer end of the limiting tube 220.

[0030] Furthermore, the thickness of the plate body 210 is set to one fifth of the length of the limiting tube 220. The plate body 210 and the limiting tube 220 are both made of metal materials. Using metal materials can ensure the strength of the plate body 210 and the limiting tube 220 and ensure that the valve core can be well protected.

[0031] Furthermore, the outer end of the pressing needle 330 is configured to be in a truncated cone shape. This shape design ensures that the outer end of the pressing needle 330 can enter the valve core, so that the exhaust operation can proceed smoothly. Embodiment 2

[0032] Combination Figure 1 and Figure 4 As shown, based on the first embodiment, the rotating shaft 310 is arranged at the top of the limiting tube 220, and the material of the rotating shaft 310 is the same as that of the plate body 210. Using the same material can reduce the difficulty of material selection when manufacturing the rotating shaft 310. Embodiment 3

[0033] Combination Figure 4 As shown, in the above embodiment, a sealing ring 400 is sleeved on the outer side of the limiting tube 220 , and the sealing ring 400 is fixedly connected to the tube cover 320 . The sealing ring 400 can improve the sealing between the tube cover 320 and the limiting tube 220 .

[0034] The working principle and use process of the utility model are as follows: when the device is put into actual use, the tire is put on the outside of the wheel hub 110, and then the valve core of the tire passes through the opening 120 and then enters the limiting tube 220, and then the tube cover 320 is tightly closed to prevent external mud and sand from entering the inside of the valve core and prevent the valve core from being damaged. Then, when exhausting, the tube cover 320 and the limiting tube 220 are separated, and then the tube cover 320 is rotated to make the pressure needle 330 face downward, and then the tube cover 320 is buckled to make the pressure needle 330 press the valve core, thereby completing the exhaust. The structure is simple and easy to use.
