Description

The twin axle hinge

The utility model relates to the hinge that case and bag are used, and refers to a kind of rubber-like especially, is applied on the foldable type device, makes the twin axle hinge that has good electrical connection and smooth outward appearance between the halved body of folding device.

In the epoch of information explosion business competition fierceness, many people carry the equipment that can store data and receive and send messages at any time, so that handle public and private affairs, communication effectively and enjoy audio-video signal etc.These carry-on equipment comprise palm PC, notes computer, WAP mobile phone, electronic dictionary, language translation machine, DVD, MD phonotape and videotape videocorder etc., and each equipment all has relevant information transmission, with audio and video recording playback Presentation Function.But, limited by the function of each equipment, the volume of these carry-on equipment all can't dwindle again, brings the problem of carrying inconvenience.Thereby on making, mostly this kind equipment is designed to foldable halved body structure, and or claim the foldable type device, when time spent not, it can be folded into the store status of cover-closing type, to dwindle its volume.

Conventionally known above-mentioned foldable type device mostly is to adopt the twin axle hinge that halved body is hinged, and the used lead that is electrically connected between the halved body then is to be interspersed in the axle of hollow.Yet, but there is following shortcoming in this telescopic twin axle hinge, as: referring to Fig. 1, the axle sleeve of being located between the halved body can form tangible projection at this position, make the foldable type device in open using, particularly when opening when being 180 ° of planes between the halved body, not only this protruding axle sleeve influence is operated, also very indecency in appearance, do not meet the high-grade requirement; In addition, be interspersed in the electric lead of quill shaft inside,, cause the faults such as wearing and tearing, short circuit of electric lead, reduce its working life also easily because of the frequent jackknife action between the keying halved body.

The purpose of this utility model is will provide in the halved body side that a kind of rubber-like, its diaxon be located at the foldable type device respectively, the structure that can between the halved body of foldable type device, form and be electrically connected and connect, can make the halved body closure or openness to suitable angle, and when opening, the halved body connection part does not have the twin axle hinge of obvious projection.

That another purpose of the present utility model provides is that a kind of foldable type device is used, connect the set depressed part in plane in the middle of utilizing comes ccontaining electric lead, can simplify assembling, regular jackknife action can not press the wearing and tearing electric lead yet, can promote the folding type device twin axle hinge in working life.

The purpose of this utility model is achieved in that a kind of twin axle hinge, mainly comprises: the first axle part, the second axle part, joint and depressed part that two axial regions are connected as a single entity; It is characterized in that: wherein shaft extension is established at the first axle part two ends respectively, and shaft extension is also established at the second axle part two ends respectively, and the shaft extension of the shaft extension of the first axle part and the second axle part is symmetrical.Establish outwardly open axial region gap between the first axle part and the second axle part two ends respectively, two axial region gaps have same depth or different depth, have suitable keying elasticity between the two axial region gaps; The inner plane of its joint is provided with depressed part, is installed in electricity and is connected to electric lead between the foldable type device halved body, covers a soft cover plate on it admittedly.

Concrete structure of the present utility model is described further by following examples and accompanying drawing:

Fig. 8, be that the utility model installs the back and open 90 ° plan view.

Fig. 9, be that the utility model installs the back and open 120 ° plan view.

Referring to Fig. 2-6, most preferred embodiment of the present utility model, a kind of twin axle hinge 20 that is applied to foldable type device 10, the mechanism that can between the

halved body

11,12 of foldable type device 10, form and be electrically connected and connect, can make halved

body

11,12 closure or openness to suitable angle, and when opening, halved

body

11,12 connection parts do not have tangible projection.

A kind of twin axle hinge 20 mainly comprises: the first axle part 21, the second axle part 22, joint 23 and depressed part 30 that two axial regions are connected as a single entity; Above-mentioned twin axle hinge 20, wherein the less shaft extension of the diameter of

axle

24,25 is established at the first axle part 21 two ends respectively, the less shaft extension of the diameter of

axle

26,27 is also established at the second axle part 22 two ends respectively, and the

shaft extension

26,27 of the

shaft extension

24,25 of the first axle part 21 and the second axle part 22 is symmetrical.

Between the first axle part 21 and the second axle part 22 two ends, establish outside opening

axial region gap

28,29 respectively, two axial region gaps, 28,29 needs according to dissimilar foldable type devices, it can be same depth, it also can be different depth, two

axial region gaps

28,29 can make to have suitable keying elasticity between the first axle part 21 and the second axle part 22.

The inner plane of its joint 23 is provided with depressed part 30, can be installed in electricity and be connected to electric lead between the foldable type device halved body 11,12.When assembling, only need electric lead is directly put into this depressed part 30, cover a soft cover plate more admittedly on the surface.Needn't electric lead be arranged in the axle as conventional sleeve cartridge type twin axle hinge, can simplify assembly operation significantly.

Referring to Fig. 7-9, in the practical application, twin axle hinge 20 of the present utility model is to be assembled in the halved body side of foldable type device 10; The first axle part 21 is located in the housing side of halfbody 11, and with the housing of this halfbody 11 between form to cooperate and contact; The second axle part 22 is located in the housing side of halfbody 12, and with the housing of this halfbody 12 between form to cooperate and contact.When opening or closing foldable type device 10, halfbody 11 is to rotate along the

shaft extension

24,25 of the first axle part 21, and another halfbody 12 is to rotate along the

shaft extension

26,27 of the second axle part 22.Because the keying elasticity between above-mentioned the first axle part 21 and the second axle part 22, make can be turned on to the

halved body

11,12 of foldable type device 10 180 and spend with interior any angle, and can be in this angle strong fix.

Advantage of the present utility model: as mentioned above: this twin axle hinge 20 is a rubber-like one twin axle hinge, two

axial regions

21,22 are installed in the halved body 11 of foldable type device 10 respectively, in 12 sides, make the halved body 11 of

foldable type device

10,12 respectively along its

shaft extension

24,25,26,27 rotate, can make halved

body

11,12 unlatchings are required angle, and when opening, at

halved body

11,12 connection parts do not have tangible projection, to satisfy high-grade demand, and, utilize the set depressed part 30 of middle interconnecting piece 20 inner planes to be installed in electric lead, can simplify assembling significantly, regular jackknife action can not press the wearing and tearing electric lead yet, so can promote the working life of foldable type device 10.
