[embodiment]

The utility model cell fixing device is applicable to portable electron devices such as mobile phone, PDA, is example in the present embodiment with the Collapsible mobile telephone.

Please refer to Figure 1 and Figure 2, Collapsible mobile telephone 1 has a housing 10, this housing 10 comprises upper shell 12 and lower house 14, upper shell 12 and lower house 14 be by hinge 16 mobilizable linking together, thereby Collapsible mobile telephone 1 can be changed between closed condition shown in Figure 1 and open mode shown in Figure 2.

Upper shell 12 comprises an outer surface 122 and an inner surface 124, and first display screen 1222 further is set on the outer surface 122, and second display screen 1242 and receiver portion 1244 further are set on the inner surface 124.

Please in conjunction with Fig. 2 and shown in Figure 3, lower house 14 comprises an outer surface 142 and an inner surface 144 equally, and outer surface 142 comprises matrix 20 and battery cover 30, and matrix 20 1 ends are provided with antenna 1426, inner surface 144 tops are provided with some function keys 1442, and the bottom is provided with number of digital key 1444.

Please refer to Fig. 4 to shown in Figure 6, matrix 20 comprises top 22, battery capacity section 24 and ring holding part 26, and the receiving space of top 22 and ring holding part 26 and the receiving space of battery capacity section 24 are distributed in the both sides of matrix 20.Top 22 has inwall 222, and battery capacity section 24 surrounds a roughly rectangular battery accommodation space jointly by roof 242, two side 244, diapire 246 and base plate 248.Battery 60 is placed in wherein.Please refer to Fig. 6 to shown in Figure 9, the inwall 222 of 22 both sides, top is provided with shell fragment accepting groove 28, and it roughly is "T"-shaped, comprises translot 282 and pod 284, and the roof 242 of pod 284 ends and battery capacity section 24 joins, and its bottom is provided with fin 286.The bottom at roof 242 two ends of matrix 20 is provided with slit 2422, and its position is corresponding with shell fragment accepting groove 28.Diapire 246 two ends of battery capacity section 24 are provided with projection accepting groove 2462, in the present embodiment, further be provided with terminal accommodating portion 2482 on the base plate 248, in order to the ccontaining conducting terminal that contacts with battery 60 (not shown), terminal accommodating portion 2482 also can be arranged on roof 242 or the sidewall 244.

Please refer to Figure 10 and shown in Figure 11, each ccontaining shell fragment 50 in the above-mentioned two shell fragment accepting grooves 28, its by elasticity preferably material such as metal make, two shell fragments, 50 shapes are identical.Shell fragment 50 comprises base portion 52 and elastic portion 54, and base portion 52 comprises that first dull and stereotyped 522 and second flat board, 524, two flat boards that are parallel to each other 526 interconnect on the top, and first dull and stereotyped 522 lateral surfaces are provided with the grab 528 of wedge shape.Elastic portion 54 extends out from the bottom 529 of second flat board 524, is bent into first kink 542, second kink 544 and half-terete contact site 546.

When shell fragment 50 is inserted the shell fragment accepting groove 28 of matrix 20, the base portion 52 of shell fragment 50 is inserted the translot 282 of shell fragment accepting groove 28, accordingly, the elastic portion 54 of shell fragment 50 is placed in its pod 284, second kink 544 of elastic portion 54 is held on the fin 286, contact site 546 probes into the slit 2422 of roof 242, and contact site 546 can be done a certain amount of rotation for axle by fin 286.By the effect of wedge shape grab 528, make base portion 52 be easy to insert in the translot 282, and need apply bigger power when extracting, thereby shell fragment 50 is closely fixed in shell fragment accepting groove 28.In other embodiments, also can adopt one or more shell fragment 50 self-contained batteries at roof 242 or one or more shell fragment accepting groove of sidewall 244 arranged outside.

Please refer to Figure 12 and shown in Figure 13, the battery 60 of Collapsible mobile telephone 1 is roughly cuboid, and a jacking block 622 is respectively established at the two ends on its top 62, and a wedge shaped projection 642 is respectively established at the two ends of bottom 64, upper bottom surface 66 is extended with shank 662 with 64 intersections, bottom, and bottom surface 68 is provided with electrode 682.

When packing battery 60 into battery capacity section 24, the top 62 of battery 60 is supported the roof 242 of battery capacity section 24, support shell fragment 50 contact sites 546 that are exposed to slit 2422 owing to jacking block 622 is corresponding with slit 2422 positions of roof 242, and insert in the slit 2422.Battery 60 is pushed to matrix 20, the wedge-type shape of the projection 642 by battery 60 is pressed in the projection accepting groove 2462 of battery capacity section 24 diapires 246 again.Battery promptly installs and by the power of seizing on both sides by the arms of shell fragment 50 battery is fixed.Because the electrode 682 on battery 60 bottom surfaces 68 is corresponding with terminal accommodating portion 2482 positions of battery capacity section 24, after battery 60 installed, electrode 682 contacted with the terminal that is contained in terminal accommodating portion 2482 (not shown), realizes conducting.In the time of need taking off battery 60, only need to the battery 60 tops 62 direction application of forces, make the jacking block 622 of battery 60 promote shell fragment 50 contact sites 546 and make its retraction at shank 662 places of battery 60, and the projection 642 of battery 60 is by deviating from the projection accepting groove 2462, again battery 60 is lifted, it can be taken out.
