The base 20 includes a fixing portion 22, and two supporting arms 23 extending from opposite ends of the fixing portion 22. The fixing portion 22 and the supporting arms 23 cooperatively form an outside surface 21 exposed to outside of the electronic device, and an inside surface 29 opposite to the outside surface 21. A receiving space 24 is defined bounded by the fixing portion 22 and the supporting arms 23, for receiving the battery module 10. Each supporting arm 23 forms a sliding rail 231 towards the receiving space 24. A circular recess 25 is defined in the outside surface 21, adjacent to one of the supporting arms 23. The recess 25 includes a bottom wall 251 parallel with the outside surface 21, and a sidewall 253 perpendicularly surrounding the bottom wall 251. A through hole 254 is defined in a middle of the bottom wall 251, and an arc-shaped slot 256 is defined in the bottom wall 251, adjacent to and along the sidewall 253. A first hook 28 is formed on the inside surface 29, adjacent to the other one of the supporting arms 23. An elongated bracket 26 is formed on the inside surface 29 between the first hook 28 and the recess 25. The bracket 26 is perpendicular to the supporting arms 23, and includes a plurality of parallel supporting plates 261, two spaced stop plates 262 adjacent to the receiving space 24, and an elongated stop plate 263 away from the receiving space 24. A fixing post 27, defining a fixing hole 271, is perpendicularly formed on the inside surface 29 between two adjacent supporting plates 261.
The operating member 30 is discoid shaped. An operating portion 33 protrudes from a side of the operating member 30. A protrusion 35, defining a fixing hole, extends from a middle of an opposite side of the operating member 30. An arc-shaped engaging tab 37 extends along a circumference of the operating member 30, in the same direction as the protrusion 35.
An elongated slot 45 is defined in the latching member 40. Two second latching portions 46 and an abutting portion 47 extend from one of two opposite lateral sides of the latching member 40. A latch 461 is formed on each second latching portion 46. A slanted surface is formed on each latch 461 away from the latching member 40. The abutting portion 47 is arranged between the second latching portions 46. The abutting portion 47 includes a slanted surface 471, for matching the slanted surface 141 of the block 14 of the battery module 10. An elongated connecting portion 41 extends from a first end of the latching member 40, and a second hook 42 extends from a second end opposite to the first end of the latching member 40. An elongated opening 413 is defined in the connecting portion 41, and a length direction of the opening 413 is perpendicular to a length direction of the latching member 40.
Referring to FIG. 7, to assemble the mounting apparatus 1, the latching member 40 is placed on the plurality of supporting plates 261 of the bracket 26, with the opposite lateral sides of the latching member 40 resisting against the stop plates 262 and 263, respectively, the second latching portions 46 and the abutting portion 47 facing the receiving space 24 of the base 20, and the fixing post 27 is inserted into the slot 45 of the latching member 40. A fastener 60 extends through the slot 45 of the latching member 40, and engages in the fixing hole 271 of the fixing post 27, to prevent the latching member 40 from disengaging from the fixing post 27. Thereby, the latching member 40 is slidably attached to the base 20. A first end of the elastic member 50 is coupled to the first hook 28 of the base 20, and a second end opposite to the first end of the elastic member 50 is coupled to the second hook 42 of the latching member 40. The operating member 30 is received in the recess 25 of the base 20. The engaging tab 37 of the operating member 30 extends through the slot 256 of the recess 25 and is received in the opening 413 of the connecting portion 41 of the latching member 40. A fastener 70 extends through the through hole 254 of the recess 25 from the inside surface 29, and then engages in the fixing hole of the protrusion 35 of the operating member 30, to prevent the operating member 30 from disengaging from the base 20. Thereby, the operating member 30 is rotatably attached to the base 20, and the mounting apparatus 1 is assembled. The elastic member 50 pulls the latching member 40 away from the operating member 30, to make the engaging tab 37 of the operating member 30 engage with a first end wall bounding the opening 413 of the latching member 40 and away from the receiving space 24.
Referring to FIGS. 4 and 5, to assemble the battery module 10, the battery module 10 is slid into the receiving space 24 of the base 20, with the grooves 153 of the battery module 10 engaging with the sliding rails 231 of the base 20, respectively. The first latching portions 12 of the battery module 10 abut against the slanted surfaces of the second latching portions 46 of the latching member 40, to push the latching member 40 to slide in a first direction, which is away from the elastic member 50. The elastic member 50 is thus stretched. A portion of the latching member 40 bounding the opening 413 pushes the engaging tab 37 of the operating member 30, to drive the operating member 30 to rotate. When the battery module 10 is entirely received in the receiving space 24, the spaces 121 of the first latching portions 12 align with the latches 461 of the second latching portions 46, respectively. The elastic member 50 is restored to pull the latching member 40 to slide in a second direction away from the first direction, until the latches 461 of the latching member 40 engage in the spaces 121 of the battery module 10. Thereby, the battery module 10 is locked.
Referring to FIG. 6, to detach the battery module 10 from the mounting apparatus 1, the operating portion 33 of the operating member 30 is rotated, to allow the engaging tab 37 to slide clockwise in the slot 256. The engaging tab 37 abuts against the portion bounding the opening 413 of the latching member 40, and pulls the latching member 40 to slide in the first direction. The second latching portions 46 are disengaged from the first latching portions 12 of the battery module 10. Thereby, the battery module 10 is unlocked. The elastic member 50 is stretched. The operating portion 33 is further rotated, to drive the latching member 40 to further slide in the first direction. The slanted surface 471 of the abutting portion 47 of the latching member 40 abuts against the slanted surface 141 of the block 14 of the battery module 10, to push the battery module 10 to slide out of the receiving space 24. When the engaging tab 37 of the operating member 30 is slid to abut against a second end wall opposite to the first end wall bounding the opening 413 of the latching member 40 adjacent to the receiving space 24, the battery module 10 is partially exited from the receiving space 24 and can be easily removed.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
