A battery module for an electric vehicle includes an external case, a battery box, a fixing mechanism, and a rotatable pull tab. The external case is fixed in the electric vehicle, and includes an accommodation space and a first fixing part. The battery box is detachably installed in the accommodation space. The fixing mechanism is disposed on the battery box. When the battery box is installed in the accommodation space, the fixing mechanism engages or disengages the first fixing part to selectively lock or unlock the battery box. When the battery box is locked, the battery box is securely fixed in the accommodation space. When the battery box is unlocked, the battery box is removable from the accommodation space. The rotatable pull tab is detachably inserted into the fixing mechanism. By rotating the rotatable pull tab the battery box is selectively locked or unlocked.

1. A battery module for an electric vehicle, the battery module comprising: an external case fixed in the electric vehicle, and comprising an accommodation space and a first fixing part;a battery box detachably installed in the accommodation space;a fixing mechanism disposed on the battery box, wherein when the battery box is installed in the accommodation space, the fixing mechanism is engaged with or disengaged from the first fixing part, so that the battery box is selectively in a locked status or an unlocked status, wherein when the battery box is in the locked status, the battery box is securely fixed in the accommodation space, wherein when the battery box is in the unlocked status, the battery box is removable from the accommodation space; anda rotatable pull tab detachably inserted into the fixing mechanism, wherein by rotating the rotatable pull tab, a relationship between the fixing mechanism and the first fixing part is adjustable, so that the battery box is selectively in the locked status or the unlocked status, wherein when the battery box is in the unlocked status, the battery box is removed from the accommodation space in response to an external force exerted on the rotatable pull tab;wherein the fixing mechanism further comprises a second fixing part corresponding to the first fixing part, wherein the second fixing part is disposed on an outer surface of the battery box, wherein the outer surface of the battery box faces an outer side of the external case, and the second fixing part is engageable with the first fixing part;wherein the first fixing part is an indentation, and the second fixing part is a pin;wherein the fixing mechanism further comprises: a rotatory disk rotatably disposed on the outer surface, and connected with the pin through a connecting rod action, wherein upon rotation of the rotatory disk, the pin is rotated relative to the outer surface, so that the pin is partially protruded out of the outer surface or the pin is not protruded out of the outer surface, wherein when the battery box is in the locked status, the pin is engaged with the indentation, wherein when the battery box is in the unlocked status, the pin is disengage from the indentation; anda guiding disk rotatably covering the rotatory disk for synchronously driving rotation of the rotatory disk, wherein the guiding disk comprises a recess. 2. The battery module as defined in claim 1, wherein the fixing mechanism further comprises an elastic positioning post, wherein the elastic positioning post is located adjacent to the rotatory disk and disposed on the outer surface. 3. The battery module as defined in claim 2, wherein the guiding disk further comprises a perforation corresponding to the elastic positioning post, wherein the elastic positioning post is penetrable through the perforation. 4. The battery module as defined in claim 3, wherein the guiding disk further comprises an outer shell, wherein the outer shell is disposed on the outer surface for sheltering the guiding disk, the pin, the elastic positioning post and the rotatory disk, wherein the outer shell comprises a guiding slot corresponding to the recess. 5. The battery module as defined in claim 4, wherein the rotatable pull tab comprises: an insertion part detachably inserted into the guiding slot;a handle part connected to a first end of the insertion part, wherein as the handle part is rotated, the rotatable pull tab is correspondingly rotated;an engaging part connected to a second end of the insertion part, wherein the insertion part is partially penetrated through the guiding slot and engaged with the recess of the guiding disk; anda pressing part disposed on the engaging part and corresponding to the elastic positioning post, wherein when the engaging part is engaged with the recess, if the elastic positioning post is pressed by the pressing part, the elastic positioning post is ejected out of the perforation. 6. The battery module as defined in claim 5, wherein the recess, the guiding slot and the engaging part have elongated profiles. 7. The battery module as defined in claim 5, wherein when the engaging part is penetrated through the guiding slot and the battery box is in the unlocked status, the engaging part is contacted with the outer shell, so that the battery box is removed from the accommodation space by pulling the rotatable pull tab. 8. The battery module as defined in claim 1, wherein the external case further comprises a guiding rail, wherein the guiding rail is formed on a bottom inner wall of the external case. 9. The battery module as defined in claim 8, wherein the battery box further comprises a guiding groove corresponding to the guiding rail, wherein the guiding groove is formed in a bottom surface of the battery box and matches with the guiding rail, so that the battery box is guided to be introduced into the accommodation space. 10. The battery module as defined in claim 9, wherein the guiding rail has an inverted trapezoid cross section, and a width of the guiding rail is gradually increased from an entrance of the accommodation space to an inner portion of the accommodation space. 11. The battery module as defined in claim 9, wherein the guiding groove has an inverted trapezoid profile, wherein a width of the guiding groove is gradually increased from the outer surface of the battery box to an inner surface of the battery box, wherein the inner surface is opposed to the outer surface.
