[0021] like Figure 1-4 As shown, a structure for quickly replacing batteries in an electric motorcycle comprises an electric motorcycle 1 and a protective shell 2, wherein an opening is formed at one end of the protective shell 2;

[0022] A battery module 3 is arranged inside the protective shell 2, and a plurality of groups of accommodating boxes 11 are arranged at intervals on the inner wall of one side of the protective shell 2. Telescopic shafts 12 are symmetrically arranged on the inner wall of the accommodating box 11, and a triangular clamping block 13 is arranged at one end of the telescopic shaft 12 close to each other. A spring 14 is sleeved on the outer side of the telescopic shaft 12. A traction shaft 15 matching the accommodating box 11 is arranged on one side of the battery module 3, and a retaining ring 16 is arranged on the outer side of the traction shaft 15. A movable hemisphere 17 is provided on the outer sliding sleeve of the traction shaft 15, and the movable hemisphere 17 is located at the front end of the retaining ring 16. A fixed hemisphere 18 is provided at one end of the traction shaft 15. The protective shell 2 is used to place the battery module 3. When the battery module 3 is installed, it can be directly pushed into the protective shell 2. During the pushing process, the fixed hemisphere 18 at one end of the traction shaft 15 squeezes the triangular clamping block toward the outside. 13, so that the spring 14 is compressed, the telescopic shaft 12 is recovered, and then the triangular clamping block 13 is between the fixed hemisphere 18 and the movable hemisphere 17, the pressure disappears, and the triangular clamping block 13 is reset and clamped between the fixed hemisphere 18 and the movable hemisphere 17, thereby forming a stable fixation for the battery module 3. When disassembly is required, the staff continues to push the battery module 3 to one side, so that the movable hemisphere 17 squeezes the triangular clamping block 13 outward. When the movable hemisphere 17 passes through the triangular clamping block 13, the staff can pull the battery module 3 outward. At this time, the movable hemisphere 17 moves closer to the fixed hemisphere 18 along the traction shaft 15, and the two are assembled into a complete sphere. At this time, the complete sphere composed of the movable hemisphere 17 and the fixed hemisphere 18 can easily push the triangular clamping block 13 outward, thereby the battery module 3 can be directly taken out, which is easy and convenient.

[0023] In the present embodiment, specifically, a partition plate 4 is provided in the center of the interior of the protective shell 2, a protrusion 5 is provided on the inner side of the protrusion 5 near the opening end of the electric motorcycle 1, a limiting groove 6 is provided on the inner side of the protrusion 5, a baffle 7 is movably provided inside the limiting groove 6, one side of the baffle 7 is in contact with the battery module 3, when the battery module 3 is placed in the protective shell 2, the baffle 7 can be inserted into the limiting groove 6, thereby forming a good limit for both sides of the battery module 3.

[0024] In the present embodiment, specifically, the inner wall of the protective shell 2 and the upper and lower end surfaces of the partition plate 4 are fitted with a plurality of groups of spaced-apart shock-absorbing rubber strips 8, which provide good shock-absorbing protection for the battery module 3, thereby minimizing the damage to the battery module 3 when the electric motorcycle 1 is bumpy, and further increasing the friction between the battery module 3 and the protective shell 2, so that the battery module 3 is not easily offset.

[0025] In the present embodiment, specifically, a sealing door 9 is movably provided at the open end of the protective shell 2, and a rubber block 10 matched with the battery module 3 is provided on one side of the sealing door 9. The movably provided sealing door 9 facilitates the staff to take out the battery module 3 from the protective shell 2, and the provided rubber block 10 can well make up for the gap between the sealing door 9 and the battery module 3, further forming a limit for the battery module 3, and avoiding left and right deviation and shaking when it is used.
