The protection assembly includes a protective cover 4, a partition 6, a first elastic member 9 and an adjustment assembly. The protective cover 4 is connected to the frame of the main body 1 of the electric vehicle. Air vents 5 are provided at both ends of the protective cover 4, and the air vents 5 are evenly distributed at equal intervals in the height direction of the protective cover 4. There are two partitions 6 symmetrically arranged. Ventilation openings 7 corresponding to the air vents 5 are provided on the partition 6. The partition 6 is slidably connected to the guide groove 8 provided on the protective cover 4. The number of the first elastic members 9 corresponds to that of the partition 6, and the first elastic members 9 are connected to the partition 6 and the protective cover 4; The first elastic member 9 is selected but not limited to a metal elastic sheet; the adjustment assembly is connected to the protective cover 4; in the use state of the adjustment assembly, the mobile end of the adjustment assembly moves horizontally to push the partition 6 to move vertically, so that the partition 6 changes from a state staggered with the air vents 5 of the protective cover 4 to an overlapping state;

[0026] In an alternative embodiment, the protective cover 4 is composed of a top plate 10, a bottom plate 11 and a protective frame 12. The top plate 10 and the bottom plate 11 are respectively connected to the upper and lower ends of the protective frame 12. The two horizontal ends of the protective frame 12 are used to form ventilation openings 5, and the guide grooves 8 are formed on the protective cover 4.

[0027] In an alternative embodiment, a sound-absorbing cotton 13 is connected to the protective frame 12. The sound-absorbing cotton 13 can absorb and reduce the noise generated by the operation of the small generator 3.

[0028] In an alternative embodiment, a plurality of corrugated plates 14 are connected to the small generator 3.

[0029] The adjusting assembly includes a driving device 15, an output shaft 16, a rotating plate 17, a moving block 18, a convex block 19, a second elastic member 20 and a guiding member 21. The driving device 15 is connected to the upper end surface of the top plate 10, and the output end of the driving device 15 is connected to the output shaft 16. The driving device 15 may be, but is not limited to, a stepper motor and a servo motor. The rotating plate 17 is arranged inside the protective cover 4 and is connected to one end of the output shaft 16. Two moving blocks 18 are symmetrically arranged, and convex blocks 19 which are symmetrically arranged are connected to both sides of the moving block 18. An inclined surface is formed at one end of the moving block 18 away from each other. The number of the second elastic members 20 corresponds to that of the moving blocks 18, and both ends of the second elastic member 20 are connected to the convex blocks 19 on the two moving blocks 18. The second elastic member 20 may be, but is not limited to, a spring. The guiding member 21 is connected to the moving block 18.

[0030] In an alternative embodiment, the guiding member 21 is composed of a limiting groove 22 and a limiting block 23. The symmetrically arranged limiting grooves 22 are formed on the top plate 10, the symmetrically arranged limiting blocks 23 are connected to the moving block 18, and the limiting block 23 is slidably connected to the limiting groove 22.

[0031] In an alternative embodiment, filter nets 24 are connected to one side of the partition plates 6 away from the protective frame 12. The filter nets 24 can filter the dust and sundries entering the protective cover 4 through the ventilation openings 7 on the partition plates 6, and avoid excessive dust being electrostatically adsorbed on the surface of the small generator 3 to reduce its own heat dissipation capacity.

[0032] In summary, when the present utility model is in use, when the battery 2 on the electric vehicle main body 1 has sufficient power, the protective cover 4 is in a closed state at this time. When the electric vehicle main body 1 travels for a certain period of time and the power consumption and endurance of the battery 2 decrease, the rider starts the controller on the electric vehicle main body 1 to control the start of the small generator 3. After the small generator 3 starts, it will generate current and transmit it to the battery 2 through the wire to increase its power. At the same time when the small generator 3 starts, the driving device 15 will also start synchronously. The output end of the driving device 15 drives the output shaft 16 and the rotating plate 17 to rotate. The rotation of the rotating plate 17 gradually increases the distance between the two moving blocks 18 through its elliptical shape, so that the moving blocks 18 and the limiting blocks 23 move along the limiting groove 22. The moving blocks 18 move away from each other and insert into the top of the partition plate 6 to push the partition plate 6 to move in the vertical direction. The partition plate 6 compresses the length of the first elastic member 9. At the same time, the ventilation openings 7 on the partition plate 6 gradually overlap with the air vents 5 on the protective cover 4 for ventilation. When the vehicle is moving, fresh air enters the protective cover 4 through the air vents 5 in front of the protective cover 4. The corrugated plate 14 connected to the protective frame 12 can increase the air residence time to enhance the heat dissipation of the small generator 3. At the same time, the filter screen 24 on the partition plate 6 filters the air to prevent dust and other sundries from adhering to the small generator 3 and affecting its heat dissipation ability.

[0033] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
