Description
[technical field]
The present invention relates to a kind of hinge, particularly relate to a kind of torsion spring type hinge, the invention still further relates to a kind of mobile phone of this hinge of application.
[background technology]
In collapsible or flip phone, the connection between body and the rotor is realized by hinge usually.Please refer to shown in Figure 5, US Patent specification US-6321415 discloses a kind of hinge 10 that is used to connect mobile phone body and rotor, comprise that an end is provided with the axostylus axostyle 12 of packing ring, and be sheathed on spring 14 on the axostylus axostyle 12 successively, cam 16 and follower 18, one end of its medi-spring 14 is fixed on the cam 16, and a microscler projection 161 is arranged on the cam 16 vertically, and follower 18 is coated on the end of axostylus axostyle 12 wherein fully.When combining with mobile phone, hinge 10 is placed in the accommodation space of relative set on the mobile phone body, and the end that its axostylus axostyle 12 exceeds packing ring passes the opening of accommodation space one end, and 18 openings by the other end of follower pass, and are fixed on the rotor.During initial condition, spring 14 is its original length, its end that exposes retaining keeping out on the device in accommodation space, and the apparent surface of cam 16 and follower 18 combines closely, and at this moment, the mobile phone body is in the relative state of opening with rotor.Relatively during the closed rotor of body, follower 18 is against and drives cam 16 on the projection 161 and rotate, and spring 14 is reversed, until this rotor by a locker snap close on body.Like this, when opening rotor once more, as long as locker is opened, rotor promptly can be by the release of spring 14 compression potential energy and the above-mentioned closing course of automatic inversion returns to open mode, and this moment, cam 16 was just got back to the state of being kept out by baffle.And the angle that is opened when rotor is crossed the follower 18 that changes and will be oppressed cam 16 along the translation of baffle direction when excessive, vertically compresses spring 14, thereby makes this rotor to be returned to the precalculated position under the restoring force of spring 14.Yet the cooperation that the cam 16 of this hinge 10 and follower are 18 is difficult for assembling mutually with mobile phone body and rotor more built on the sand.

[embodiment]
With reference to shown in Figure 1, hinge 200 comprises axostylus axostyle 21 in the invention hinge embodiment, cam 22, stage clip 23, torsion spring 24, sleeve 25, and card 26.
Axostylus axostyle 21 1 ends have two spokes 211 to external radiation, and this two spoke 211 is positioned on the same diameter, and support a spoke wheel 212 simultaneously.The other end of axostylus axostyle 21 offers an annular groove 213 that is used to fix card 26.The middle part of axostylus axostyle 21 also offers a fixing hole 214 that is used for fixing torsion spring 24 1 ends.
Please together with reference to shown in Figure 2, cam 22 comprises the middle tube 223 at a cam end 221, one block ends 222 and middle part, and its whole length is less than the distance of fixing hole 214 on the axostylus axostyle 21 to 212 of spoke wheels.Wherein end face 2210 epireliefs of cam end 221 have two protruding peaks 2211, this two protruding peak 2211 is positioned at both sides relative on the end face 2210, all have a wall 2212 and a curved surface that seamlessly transits 2213, wherein, curved surface 2213 is for transitting to the top of wall 2212 by end face 2210 level and smooth risings, and the part near wall 2212 tops on it also is provided with a step surface 2214.222 of block ends comprise four by projection 2230 outwards outstanding around the middle tube 223.The aperture of middle tube 223 is greater than the diameter of axostylus axostyle 21, and the length of whole cam 22 is less than the length of axostylus axostyle 21.
The length of tube 223 is suitable in the length of stage clip 23 and the cam 22.
With reference to figure 3 and shown in Figure 4, during assembling, at first stage clip 23 is fixed on the middle tube 223 of cam 22, the cam 22 that will have stage clip 23 then is enclosed within on the axostylus axostyle 21, and make cam 22 spoke wheel 212 near axostylus axostyles 21, fixing hole on the axostylus axostyle 21 214 is exposed, and the cam end 221 of its cam 22 is towards spoke wheel 212; End with torsion spring 24 is fixed in the fixing hole 214 again, and the other end is fixed in the fixing hole 251 on the sleeve 25; Last suitably rotation and compression sleeve 25, but make four protruding arms 250 on it just insert between four projections 2230 of cam 22 and the endwisely slipping of direct-axis bar 21, and make the annular groove 213 of axostylus axostyle 21 stretch out, and blocked by card 26 by the semiclosed opening of sleeve 25.Can see that after installing, all parts of whole hinge 200 just firmly are connected together, form the integral body of the assembly that can not be scattered.
When this hinge 200 is applied to mobile phone, axostylus axostyle 21 and sleeve 25 can be linked with the body and the rotor of mobile phone respectively.During initial condition, torsion spring 24 is its reset condition, and two spokes 211 on the axostylus axostyle 21 support respectively on cam 22 end faces 2210, and at this moment, the mobile phone body is in the relative state of opening with rotor.Relatively during the closed rotor of body, axostylus axostyle 21 is with respect to sleeve 25 rotations, thereby make spoke 211 on cam 22 end faces 2210, move, torsion spring 24 is reversed simultaneously, until this rotor by a locker snap close on body, this moment, spoke 211 just turned to protruding peak 2211 walls 2212 times on cam 22 end faces 2210.Like this, when opening rotor once more, as long as locker is opened, rotor promptly can be by the release of torsion spring 24 torsional-energies and the above-mentioned closing course of automatic inversion, return to open mode, this moment, two spokes 211 should just be got back to 2211 underfooting, two protruding peaks on cam 22 end faces 2210.Opened excessively and work as rotor, two spokes 211 continue to slide along cam 22 end faces 2210, the gradient at protruding peak 2211 will produce resistance to the climbing of spoke 211, at this moment, be reversed the torsion spring 24 that reverses, reach compressed stage clip 23 and also the slip to spoke 211 is simultaneously produced obstruction, thereby made the rotor of opening automatically reset.Spend suddenly or excessive and cross tensile force, make when two spokes 211 slide on the step surface 2214 that this two spoke 211 will be stayed on step surface 2214, so more can avoid rotor to cross the impact that is caused when opening with respect to body when this.
