[0036] Reference Figure 2 and Figure 7 A circular water box 27 is provided in the protective shell 1. The water box 27 is located on the outside of the battery. A rectangular opening 28 is opened on the protective shell 1 to communicate with the water box 27. A plurality of heat sinks 29 extending into the water box 27 are fixedly connected to the protective shell 1. On rainy days, rainwater can enter the water box 27 through the rectangular opening 28. A large amount of heat is generated during the operation of the battery. The heat is transferred to the heat sink 29 through the protective shell 1. The heat sink 29 is located in the water in the water box 27. The water can take away the heat from the heat sink 29, thereby achieving a better heat dissipation effect.

[0037] Reference Figure 2 A second threaded rod 31 is threadedly connected to the protective shell 1, and one end of the second threaded rod 31 is rotatably connected to a closing plate 30. The closing plate 30 is slidably connected in the protective shell 1, and the closing plate 30 is used to close the rectangular opening 28; when the water in the water box 27 is full, the second threaded rod 31 is rotated, and the second threaded rod 31 drives the closing plate 30 to move, so that the closing plate 30 can close the rectangular opening 28 to prevent rainwater from entering the water box 27 again.

[0038] Reference Figure 7The water box 27 and the protective shell 1 are rotatably connected with a rotating shaft 32, and both ends of the rotating shaft 32 are fixedly connected to a rotating block 33, and the outer wall of the rotating block 33 is fixedly connected to a plurality of blades 34; when the electric bicycle is running, the wind will cause the outer blades 34 to rotate, and the outer blades 34 drive the blades 34 in the water box 27 to rotate through the rotating shaft 32. The rotation of the inner blades 34 can drive the water in the water box 27 to circulate, thereby achieving better heat dissipation.

[0039] Working principle: When in use, install the protective shell 1 on the electric bicycle, open the protective cover 2, and place the battery in the protective shell 1. When the bottom of the protective shell 1 is bumped or hit, the reminder component can remind the user to repair the protective shell 1 in time. When the impact on the protective shell 1 is serious, causing the battery to be damaged, the battery will smoke and gradually catch fire. The processing component can deal with it in time, which can delay the battery fire time and give the user enough time to escape;

[0040] When the bottom of the protective shell 1 is impacted and the battery is damaged, the pressure plate 9 moves downward. The downward movement of the pressure plate 9 can compress the airbag 4, increasing the air pressure in the airbag 4. The carbon dioxide gas will compress the blocking ball 8, pushing the blocking ball 8 away from the fixing seat 6. The connecting rope 7 is stretched, and the carbon dioxide gas is discharged from the discharge pipe 5 and discharged directly above the battery. The carbon dioxide can delay the ignition of the battery and play a role in temporarily suppressing the fire. When the pressure of the pressure plate 9 disappears, the blocking ball 8 re-seals the discharge pipe 5 under the action of the connecting rope 7;

[0041] When the bottom of the protective shell 1 is slightly hit and punctured, but the battery is not damaged, the liquid capsule 14 will also be punctured, and the liquid in the liquid capsule 14 will spray out pigment to remind the user that the bottom of the protective shell 1 is damaged. When the bottom of the protective shell 1 is hit hard and the battery is also affected, the flat plate 13 above the liquid capsule 14 is also pushed upward and the first spring 12 is compressed.

[0042] When the bottom of the protective shell 1 is violently impacted, the flat plate 13 above the liquid capsule 14 is also pushed upward, and the flat plate 13 drives the bottom end of the first connecting line 15 to move upward, and the first connecting block 16 and the second connecting block 17 are pulled by the first connecting line 15. The second connecting block 17 pulls the vertical column 10 downward through the second connecting line 18. The vertical column 10 drives the pressure plate 9 downward, and the pressure plate 9 presses the airbag 4;

[0043] When it is necessary to open the protective cover 2 to place the battery, the first threaded rod 22 is rotated, and the first threaded rod 22 drives the movable plate 23 to move upward. The movable plate 23 drives the insert block 26 upward through the first magnetic piece 24 and the second magnetic piece 25, so that the insert block 26 leaves the slot 21, and the connection between the two connecting blocks 20 is released. The protective cover 2 can then be opened to place the battery. After placement is completed, the protective cover 2 is closed, and the first threaded rod 22 is rotated to insert the insert block 26 into the two slots 21, so that the two connecting blocks 20 are reconnected. When the bottom of the protective shell 1 is violently impacted, the flat plate 13 above the liquid capsule 14 is also pushed upward. The flat plate 13 can pull the first connecting block 16 and the second connecting block 17 through the first connecting line 15 to move, so that the first magnetic piece 24 and the second magnetic piece 25 are separated, and the first connecting block 16 enters the rectangular groove 35. The second spring 36 is compressed. When the flat plate 13 is reset, under the action of the second spring 36, the first connecting block 16 is reset, and the first magnetic piece 24 and the second magnetic piece 25 are again in contact and attracted to each other.

[0044] On rainy days, rainwater can enter the water box 27 through the rectangular opening 28. During the operation of the battery, a large amount of heat is generated. The heat is transferred to the heat sink 29 through the protective shell 1. The heat sink 29 is located in the water in the water box 27. The water can take away the heat from the heat sink 29, achieving a better heat dissipation effect.

[0045] When the water in the water box 27 is full, the second threaded rod 31 is rotated, and the second threaded rod 31 drives the closing plate 30 to move, so that the closing plate 30 can close the rectangular opening 28 to prevent rainwater from entering the water box 27 again;

[0046] When the electric bicycle is running, the wind will cause the outer blades 34 to rotate, and the outer blades 34 drive the blades 34 in the water box 27 to rotate through the rotating shaft 32. The rotation of the inner blades 34 can drive the water in the water box 27 to circulate, thereby achieving better heat dissipation.
