Summary of the invention

The problem that invention is solved

Because the clamshell handset of record all is to connect lid housing (reception housing) and body shell (sending the words housing) by the articulated mechanism that can freely fold in above-mentioned patent documentation 1,2, therefore, can carry out folding and opening of lid housing and body shell smoothly.

But, since above-mentioned patent documentation 1 in disclosed clamshell handset in the 1st block, hold hinge assembly with driver part, therefore, the profile of the 1st block is bigger, the 2nd block since will with the form fit of the 1st block, so profile is also bigger.Like this, this mobile phone is opening under the state, and joint just becomes the state that the cylindrical protrusion thing stretches out.If in joint, there is this thrust, then makes the user can be appreciated that the existence of this protrusion, thereby stay the impression of the exposed mechanical parts that lack design.In addition, the existence of this thrust will be dwindled the use surface area of lid housing and body shell.Particularly, because body shell is locating to be provided with operated key in abutting connection with these joints (being the columnar protrusion thing), therefore, if there is this thrust, then the operating space of operated key diminishes, thereby can limit set operated key quantity, and finger is also run into thrust easily and is influenced operation when operation.

In addition, therefore the clamshell handset that discloses in above-mentioned patent documentation 2, can not form projection at the joint that send words, reception housing owing to be provided with 2 axes of rotation, so, be flat on the surface of opening under the state.And, send words, receive housing and connected element on the 1st, the 2nd spin axis L1, L2 respectively by a pair of the 1st, the 2nd hinged the connection, independent respectively, the rotation separately of these hinging pars.

But, in above-mentioned patent documentation 2 in the disclosed clamshell handset, connected element 92 forms by resin or metal drip molding, because sending words, reception housing 91,94 is generally made by resin material, therefore, consider design, this connected element 92 is preferably also formed by same resin material.But if this connected element 92 is formed by resin material, then mechanical strength is lower, and handset switch action repeatedly may cause breakage, thereby unsatisfactory.On the contrary, if this connected element 92 make by metallic material, though its mechanical strength can improve,, because different, therefore, impair design with the material that send words, receive housing 91,94.

Moreover, because in the clamshell handset of above-mentioned patent documentation 1,2 records, the parts that constitute articulated mechanism are connected to each other with sending words, reception housing, therefore, along with the switch that send words, reception housing, hinging par can produce friction, the sound that this friction meeting cannot not made us happyly user's generation, for example squeak with sending words, reception housing.For fear of producing this sound, send words, receive being connected between housing and the articulated mechanism if loosen, then can eliminate this sound, but can between housing and articulated mechanism, produce the gap like this, thereby can cause the folding folding instability of sending words, receiving housing.

In view of the above problems, the inventor is from having carried out found that of various researchs to the linkage structure of taking into account aesthetic property and mechanical strength, when using metal articulated mechanism, cover this articulated mechanism by outer cover, and then adopt the outer cover fixing means to address the above problem, thereby the present invention has been proposed.

The inventor also finds, adopt 2 shaft type articulated mechanisms, and, make this articulated mechanism have the thickness that can not stretch out under the state from the mobile phone surface opening, and then by making a pair of machine case remain the symmetry rotation with respect to articulated mechanism, thereby can realize stablizing, rotational action smoothly, simultaneously, articulated mechanism can not influence the operation of key, and, can provide design higher collapsible machine, thereby propose the present invention.

That is, the object of the present invention is to provide a kind of raising to be provided with the Foldable device of design, operability and mechanical strength of joint of the Foldable device of a pair of machine case.

And, to install under the state of two coverings 7,8, the wall ratio of hinged cover C send the wall thickness that receives housing 2,10 thin slightly or about equally.This is because hinged cover C is stretched out in the surface side of mobile phone 1, and better is that the surface location of hinged cover C is positioned on the elongation line of the surface location that send words, receives housing 2,10.The bottom surface of the box-shaped covering 8 by making surface side forms tabular surface, thereby when making mobile phone 1 reach the state of opening or mediating, forms the continuous face of segmentation bending to hinged cover C and the surface that receives housing 10 from sending words housing 2.

In addition, the bottom surface of the covering 7 of back side also forms tabular surface., under the state of folding cell phone 1, the bottom surface of this covering 8 is placed as the placed side by this tabular surface, thereby when the camera function that uses mobile phone 1 carries out BR, needn't use the special device that is used for fixing camera to take.

In addition, shown in Figure 10 a, Figure 11 a, Figure 12 a, because a covering 7 is fixed on the bonding pad 31 of connected element 30, therefore by screw 9, hinged cover C is stable with respect to articulated mechanism 20, and hinged cover C can be in the 15a～15b of each bight move along left and right directions etc.

Like this, by fastening screw trip bolt mount inlet 7b, 8b being arranged in abutting connection with the side end longitudinally that send words housing 2 or reception housing 10, therefore, no matter send words, receive the state that housing 2,10 folds (referring to Figure 10 a) or the state of opening predetermined angular (referring to Figure 11 a and Figure 12 free position a), screw 9 all can not expose from sending words housing 2 and reception housing 10, promptly can't see from the outside, thereby can improve aesthetic property.

Shown in Fig. 6 and Figure 10 b, sending words, receiving housing 2,10 and be in the articulated mechanism 20 under the folded state, the 1st, the 2nd framework 21,41 forms the almost parallel states.Promptly, in each stop component 71,71, the fastening pawl 71a that is arranged on the stop component 71 in the 4th joint 104 contacts with the fastening projection 37b of the 4th connecting part 37 of connected element 30, and the fastening pawl 71a that is arranged on the stop component 71 in the 2nd joint 102 is positioned at the position of the fastening projection 35b that leaves the 2nd connecting part 35 slightly.That is, when mobile phone 1 is in closed condition, have only one not contact among the fastening pawl 71a of 2 stop components 71 with fastening projection 37b.This means the words of sending when mobile phone 1, receive housing 2, when 10 switching angle is 160 °, will be (for example big 1 °～about 3 ° for being a bit larger tham 160 ° by the switching angular setting that stop component 71 limits, be about 0.5～1.5 ° of each rotatingshaft), like this, if make the angle that limits by stop component 71 open and close angle greater than reality, even for example in off position, owing to be not subjected to stop component 71 restrictions, therefore, by driving mechanism 50 make send words housing 2, receive housing 10 and be in the state that mutual roof pressure loads, receive housing 2 thereby send can prevent in off position the time, produce the slit between 10.Though a contacted situation in the stop component 71,71 is illustrated herein,, in fact also can make two stop components all keep some slits (with the rotatingshaft is 0.5～1.5 ° at center, is preferably 1 °).In this case, when send words, when receiving housing 2,10 and being in closed condition or opening state, two are sent words, receive housing 2,10 and support mutually by butt joint each other.

Afterwards, if from this folded state, make a housing (for example, receiving housing 10) is rotated predetermined angular, then another send words housing 2 also will rotate same angle in the opposite direction.For example, shown in Fig. 7 and Figure 11 a, in the time will sending words, receive housing 2,10 and open 80 °, articulated mechanism 20 is shown in Figure 11 b, and the 1st, the 2nd framework 21,41 rotates equal angular mutually in the opposite direction with respect to connected element 30, promptly all rotates 40 °.

And then, if rotate to send words, reception housing 2,10 and to open it to formation and open state (promptly 160 °), then articulated mechanism 20 is shown in Fig. 8 and Figure 12 b, 1st, the 2nd framework 21,41 all rotates 80 ° mutually with respect to connected element 30, in addition, opening under 160 ° the state, contacting by two bight 15a, 15b, 16a, 16b that send words, receive housing 2,10 keeps opening state, and stop component 71,71 is positioned at the position of leaving micro-gap (2 °) with respect to fastening projection 35b, 37b.But, when opening state, such micro-gap can certainly be set, make send words, receive housing 2,10 contacts in, stop component 71,71 is also contacted with fastening projection 35b, 37b.

Like this, because the mobile phone 1 of present embodiment reaching from closed condition when opening state,, therefore, form level and smooth bent state shown in from the side, thereby design is better from sending words housing 2 to hinged cover C and receive housing 10 and form the beautiful continuously of segmentation warpages.

Figure 13 is the profile of observing from the B direction of Figure 10 a.As shown in the drawing, when covering articulated mechanism 20 by covering 7,8, connection by send words, receive each bight 15a, the 15b of housing 2,10 and 16a, the lateral length in the slit of the articulated mechanism 20 of 16b clamping is greater than the lateral length of the covering 7,8 that constitutes hinged cover C, between the side of covering 7,8 and each bight 15a, the 15b that send words, reception housing 2,10 and 16a, 16b formation have specific length d than small gap.If form the slit in this position, then when sending the on-off action that receives housing 2,10, send words, reception housing 2,10 and covering 7,8 can not rub mutually and send the squeak of friction.Certainly, should preferably adopt the structure of difficult intrusions such as dust than small gap.In addition, because a covering 7 is fixed in by screw 9 on the bonding pad 31 of connected element 30, therefore, the side of covering 7,8 keeps necessarily with sending the length than small gap that forms between each bight 15a, the 15b that receive housing 2,10 and 16a, the 16b.

As mentioned above, since embodiment's articulated mechanism by linkage mechanism 60 drive the 1st, the 2nd framework 21,41 with respect to connected element 30 with the opposite position rotation that links, therefore, only a framework can not rotate, all the time two framework interlocks are rotated, so, can realize stable on-off action, simultaneously, sending words, receive housing 2,10 and dislocation also can not occur under in off position.

In this embodiment, though driving mechanism 50 is arranged at 101,103 two places of the 1st, the 3rd joint,, also it can be arranged on any joint of the 1st～the 4th joint 101～104.But if driving mechanism 50 has only one, owing to play or loosening can appear in the reason of backlash, therefore, preferably each running shaft all is provided with one.In addition, though linkage mechanism 60 is arranged on the 1st, the 3rd joint 101,103 that is provided with driving mechanism 50, but, if the 1st framework 21 is connected also with the 2nd framework 41 can be located at Anywhere, best so that the 1st arm sheet 22 is provided with so that reach with the mode that the 3rd arm sheet 42 or the 2nd arm sheet 24 link to each other with the 4th arm sheet 44 and saves the space most.

In addition, for stop mechanism 70, though be arranged in this embodiment in the 2nd, the 4th joint 102,104,, also can be arranged on any joint place, best, the same with driving mechanism, each running shaft is provided with one.In addition, it will be understood by those skilled in the art that: this stop mechanism 70 also can be arranged on the joint that is provided with driving mechanism 50 and linkage mechanism 60.

Articulated mechanism can not protrude in the mobile phone surface to above-mentioned mobile phone under the state opening, and, 2 running shafts are always with the opposite position equal angular that rotates, therefore, can stablize and successfully carry out rotational action, and, no matter open state or closed condition, its surface all can reach level and smooth bent state, therefore, can form the higher mobile phone of appearance design.
