[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This high-protection electric vehicle motor, when the road surface is icy, can improve the stability of the electric vehicle by opening the protective cover and unfolding the telescopic sliding rod by turning the knob. The protective cone can be inserted into the ice surface. In rainy weather, replacing the anti-slip rubber support improves the overall grip of the electric vehicle and enhances riding safety. The heat dissipation holes inside the spiral heat dissipation plate guide the heat generated by the motor body, causing the heat to flow towards the heat dissipation fins on the outside of the wheel hub end cover, further improving heat dissipation efficiency. The specific details are as follows:

[0022] 1. By setting up a protective mechanism, not only can the electric vehicle motor be protected with a protective cover, but also the rotating worm gear can be rotated by turning the knob. Utilizing the meshing connection between the worm gear and the worm wheel, the worm wheel rotates. Under the limiting action of the spiral groove inside the worm wheel, the spiral slider drives the connecting block and the telescopic sliding rod to extend and retract. When the road surface is icy, the protective cover can be opened, and the telescopic sliding rod can be extended by turning the knob. The protective cone can then be inserted into the ice, thereby improving the overall stability of the electric vehicle. Simultaneously, by pressing down on the locking disc, when the locking groove separates from the locking gear, rotating the mounting plate drives the connecting rod and... When the limit block rotates and moves past the engaging spring and engaging protrusion to the bottom of the mounting limit groove, the mounting plate and protective cone can be pulled out upwards to replace the protective cone. This allows for the replacement of the anti-slip rubber support in rainy weather, thereby improving the overall grip of the electric vehicle. At the same time, the widening method improves the stability of the electric vehicle, which is helpful for novice riders and enhances the safety of riding the electric vehicle. When the protective cone is not needed, it can be removed and a certain barrier can be formed by quickly rotating the telescopic sliding rod. This can prevent stones from the road surface from hitting the electric vehicle's wheel hub and motor body, thus avoiding damage to the motor body.

[0023] 2. By setting up a heat dissipation mechanism, not only can the hub end cover and protective mechanism be installed and fixed using mounting bolts, but the heat dissipation fins can also transfer the heat generated by the motor body to the outside. The wind generated during riding further cools the motor body rapidly, thus reducing its temperature and preventing overheating that could cause it to burn out, thereby extending its service life. When the motor body drives the electric vehicle's wheel hub to rotate, the first fixed heat dissipation ring, the spiral heat dissipation plate, and the second fixed heat dissipation ring can rotate. The heat dissipation holes inside the spiral heat dissipation plate guide the heat generated by the motor body, causing it to flow towards the heat dissipation fins on the outside of the hub end cover, further improving heat dissipation efficiency.
