Holding part 250 comprises 215 the first flat board 252, the second flat board 254 and the limit bodies 256 that vertically extend to form from bottom surface.First dull and stereotyped the 252 and second flat board 254 is parallel to each other, and surrounds accommodation space 258 with bottom surface 215.The first flat board 252 is provided with opening 2522.Limit body 256 is the square column between first dull and stereotyped the 252 and second flat board 254, and its position with opening 2522 is corresponding.

Lid 300 is roughly cuboid, and the shape of its shape and depressed part 210 is suitable.Lid 300 is provided with two snap fits 320 and two Plug Divisions 340.Snap fit 320 and Plug Division 340 are arranged at respectively the opposite end of lid 300.The hook of two snap fits 320 extends in opposite directions.

Opening structure 400 comprises sensing element 410, telescopic magnetic part 420, is inserted in two buckling pieces 430 at magnetic part two ends, reaches two telescopic ejection pieces 445.Sensing element 410 is for the touch sensitive signal.In the present embodiment, sensing element 410 is made of metal, usually all there is bio-electric field in human body, when touching metal sensing element 400, can on sensing element 400, induce electric charge, now human body and sensing element 400 be owing to there being the different electric charge of polarity, thereby form touch signal.Sensing element 410 comprises the connecting portion 414 that rectangle induction part 412 and self-induction section 412 1 ends extend to form.

The loop that magnetic coil 422,424 series connection that magnetic part 420 is two form.Two magnetic coils 422,424 coaxially arrange, and the two relative end 4232 linearly connects, and the two opposing end 4234 extends and surrounds limited mouth 4236 with opposite end 4232 to the direction away from opposite end 4232 is vertical again after extending in opposite directions contact.

Buckling piece 430 comprises the buckling parts 434 that cylindrical fixed part 432 and self-retaining section 432 1 ends extend to form.Ejection piece 445 comprises spring 440 and is connected to the ejection part 450 of spring 440.Ejection part 450 roughly is the boss shape, and it comprises the first cylinder 452 that is connected to spring 440 and the second cylinder 454 extended to form to the direction away from spring 440 from the first cylinder 452.The diameter of the first cylinder 452 is greater than the diameter of the second through hole 280 and is less than the diameter of the first through hole 262.The diameter of the second cylinder 454 is less than the diameter of the second through hole 280.

During assembling, first limit body 256 is passed to the limited mouth 4236 of magnetic part 420, magnetic part 420 is fixed in the accommodation space 258 of holding part 250, two coils 422,424 lay respectively at limit body 256 both sides and between two resettlement sections 260, and opposing end 4234 is positioned at opening 2522 and lays respectively at the other relative both sides of limit body 256 with opposite end 4322.Again the fixed part of two buckling pieces 430 432 is inserted respectively to the two ends of magnetic part 420, simultaneously two two ends that buckling parts 434 stretches out respectively magnetic part 420.Then ejection part 450 is placed in the first through hole 262 of resettlement section 260, the second cylinder 454 will insert the second through hole 280, and spring 440 is placed in the second through hole 280 and connects with the first cylinder 452 of ejection part 450.Again display screen 500, circuit board 600 being placed in to the first shell 100 makes display screen 500 come out by opening 160.Again the first shell 100 is engaged with second housing 200 afterwards, the opposing end 4234 of magnetic part 420 is electrically connected to circuit board 600.Again the induction part of sensing element 410 412 is positioned in the depressed part 210 of second housing 200 and connecting portion 414 is electrically connected to circuit board 600.Finally battery 700 is aimed to opening 240 and put into accommodation space 800, two jacks 290 of second housing 200 are inserted respectively in two Plug Divisions 340 of lid 300, two snap fits 320 are fastened on the buckling parts 434 of two buckling pieces 430 through two on second housing 200 perforation 270 respectively, lid 300 is covered on depressed part 210, and simultaneously two springs 440 are subject to the extruding of lid 300 away from an end of the first cylinder 452 and lid 300 butts and elastic deformation occurs.Electronic equipment 99 has been assembled.

As shown in Figure 6, if wish is changed the battery 700 of electronic equipment 99, use the induction part 412 of finger touch sensing element 410, sensing element 410 produces touch signal and sends touch signal to circuit board 600.Circuit board 600 response touch signals give magnetic part 420 energisings by opposing end 4234.Now, magnetic part 420 will attract each other and shrink because of each coil after its energising, and drive that two buckling pieces 430 are mobile in opposite directions makes two snap fits 320 separate with the buckling parts 434 of two buckling pieces 430.Two springs 440 recover elastic force that elastic deformations produce and will drive two ejection parts 450 and move and promote lid 300 and move, thereby can the second housing 200 separation from housing 188 by lid 300, more convenient.
