In order to adjust the development rate of mobile terminal reposefully, can between stationary cam 60 and sliding cam 50, provide reliable cooperation.According to one embodiment of the present invention, the pressure spring 70 that is arranged between supporter 40 and the sliding cam can be by support member, to apply elastic force to sliding cam continuously.Therefore, sliding cam can closely contact with stationary cam 60 constantly by pressure spring, thereby provides reliable damping function for hinge assembly.
Therefore, can use hinge assembly 100 based on this mode of execution automatically to launch mobile terminal, this hinge assembly does not need to use the motor that needs power consumption, and can realize the steady expansion action of mobile terminal.
Equally, according to this mode of execution, to shown in Figure 4, damper 200 can combine with axle as Fig. 2, with the rotating speed of damping axle and be that mobile terminal provides and launches action more stably.In this specific implementations, the opposite side of axle can pass sliding cam and stationary cam combines with damper.
Fig. 4 and Fig. 5 are a kind of perspective exploded view of implementing the damper in every hinge assembly according to the present invention.With reference to Fig. 4 and Fig. 5 damper 200 according to the hinge assembly of one embodiment of the present invention is described below.
According to one embodiment of the present invention, shown in Figure 4 and 5, second shell 220 that damper 200 can comprise first shell 210, combine with this first shell in the mode of allow sliding and rotate and with this second shell in abutting connection with being provided with to limit the block 230 of second shell rotation.
Viscous fluid can be filled in inner space between first shell 210 and second shell 220.Can between first shell 210 and second shell 220, inject viscous fluid and think that the relative movement of first shell and second shell provides frictional force.Can between first shell 210 and second shell 220, inject viscous fluid and sealing.This viscous fluid can be the very high fluid of viscosity, can be by applying frictional force and the rotating speed of damping axle to relatively rotating of first shell and second shell.So, the lubricant oil of high viscosity or silicone oil can be used as this viscous fluid.
Shown as the embodiment among Fig. 5, first shell 210 can comprise core 212 and flange 214, has the inner space between core and the flange.
Can on second shell 220, form towards the friction projection 224 of the direction projection of first shell 210.Can form this friction projection 224 allowing friction projection 224 to be inserted on the position in the inner space of defining by core 212 and flange 214.Except go into to have the friction projection at the spatial interpolation between core and the flange, in this space, inject viscous fluid, and viscous fluid can apply bigger frictional force to second shell.
Block 230 (by block, second shell 220 that rotates with first shell 210 can be blocked and can not rotate in the location) can combine with housing.The block that is fixed in housing can stop the rotation of second shell in the special angle scope.
According to this mode of execution, second shell 220 and block 230 can be with the mode combinations that allows to slide.Shown as embodiment among Fig. 4, can second shell in the face of and contact blocks the surface in formation guide groove 226.Guide groove can be the Baltimore groove that forms in a surface of second shell, and when from one of this second shell outwardly the time, its shape is as the circular arc that is formed centrally special angle in centering on.This arc guide barrel 226 can be formed in the surface of second shell symmetrically.
On the contrary, lock pin projection 232 can be formed on the surface of the block 230 of second shell 220.The lock pin projection can be formed on and corresponding position, the position of guide groove, so that the lock pin projection can be inserted in the guide groove.As shown in Figure 4, two lock pin projections can be arranged, each can insert in the guide groove 226 that is symmetrically formed.
Therefore, owing to can be formed with lock pin projection 232 on the block 230, therefore second shell 220 can stop operating in specific angle with the axle and first shell 210.Because the lock pin projection can be inserted in the guide groove 226 of second shell 220, the block 230 that is formed with lock pin projection 232 on it can be fixed in housing, and second shell can rotate in the special angle that is limited by guide groove.
In the location that the rotation of second shell is restricted, first shell 210 and second shell can relatively rotate with respect to each other.If second shell was static when first shell rotated, then first shell may be subjected to the frictional force that applied by viscous fluid continuously.Therefore, when second shell is limited by block 230 and can not rotate, rotating speed that can the damping axle.
On the other hand, if axle and first shell, 210 backward rotation, second shell 220 may link with first shell and axle once more, reaches specific angle up to it, and the rotation of second shell may be stoped by block 230 once more in this angle.Therefore, the some place that can be prevented from away from the rotation of second shell realizes the function of damper 200 in opposite direction.
According to one embodiment of the present invention, the rotating speed of axle can be damped in the rotary location of axle.Damped in the location that the rotating speed of axle can be limited by block 230 in the rotation of second shell 220.Therefore, be formed on guide groove 226 in second shell, just can adjust the zone that damping function is implemented by change.That is, the two ends by changing each guide groove 226 are about the angle that the central part of second shell forms, and just can adjust that second shell is not subjected to the restriction of block 230 and the zone of rotating.
As mentioned above, axle can combine with damper 200, and damper can be at the rotating speed of the rotary special angle internal damping of axle axle.Therefore, in the mobile terminal that is equipped with hinge assembly based on specific implementations of the present invention, folding unit can launch reposefully, and its to greatest extent start point be not subjected to the influence of elastic energy.
The aforesaid specific implementations according to the present invention by use torsion spring in the hinge assembly structure, can produce the mobile terminal that only uses a few components just can launch automatically reposefully.
Although describe spirit of the present invention in detail with reference to specific embodiment, these embodiments only are used for the example purpose, do not really want to limit the present invention.Should be appreciated that under the condition that does not deviate from scope and spirit of the present invention those skilled in the art can change or revises embodiment.
