Abstract
A magnetic rotary device comprises a base body and a rotary body. The base body has a fixed portion, the rotary body has a shaft portion. When the fixed portion is coupled with the shaft portion, the rotary body will rotate relative to the base body, and form a first or a second stable status. The magnetic rotary device also comprises a magnetic member of the base body that is in the fixed portion, a magnetic member of the shaft that is in the shaft portion and match with the magnetic member of the base body in pairs. When the base body and the rotary body are in the first stable status, the magnetic member of the shaft is in one side of the magnetic member of the base body. When the base body and the rotary body are in the second stable status, the magnetic member of the shaft is in another side of the magnetic member of the base body.
Description
Technical field
The present invention relates to a kind of rotating mechanism, particularly relate to a kind of rotating mechanism that utilizes magnetic principles.
Background technology
Have many electronic products all to have the design of flip now, the advantage of cover-lifting type design is, the part easily impaired, that make dirty of electronic product had defencive function, for example the screen of mobile phone, button ... etc.In addition, also can increase the elasticity in the appearance design, give the how different impression of user.Please refer to Fig. 1, what it illustrated is the schematic diagram of cover-lifting type mobile phone.Cover-lifting type mobile phone 100 has comprised mobile phone body 110 and flip 120, and both couple at rotating mechanism 130 places, and flip 120 can be changed between two states of open and close along arrow direction among the figure with respect to mobile phone body 110 rotations.In the design of rotating mechanism 130, the general hinge that cooperates spring or spring-piece type with cam (cam) that adopts makes flip 120 can be stable at the open and close state according to the effect of elastic force at present.In the use, because spring (sheet) is easy to generate elastic fatigue in repeatedly unlatching and after closing, usually can allow spring (sheet) produce the problem that torsion reduces.In addition, the very easy wearing and tearing of cam also are problems, and the cam of serious wear can make spring (sheet) lack elastic force in use because of deformation is not enough.More than two phenomenons the life-span of the hinge rotating shaft of conventional cam-spring (sheet) formula is lowered, bring the user inconvenience.
Summary of the invention
For addressing the above problem, the present invention utilizes a rotating mechanism that simply has magnetic, the hinge that replaces cam-spring (sheet) formula, make flip have the function that nature is opened and closed, simultaneously because the axle body that directly utilizes rotating mechanism as the mechanism with hinge function, can effectively reduce the structure requisite space.
The scheme that solves the problems of the technologies described above is, a kind of rotating mechanism with magnetic is provided, and comprises matrix and rotary body.Matrix has fixed part, rotary body has axial region, can make rotary body with respect to matrix rotation and be positioned first stable state or second stable state when fixed part and axial region couple, the rotating mechanism that this kind has magnetic has also comprised: the matrix magnetic element is arranged at the fixed part place; And the axis body magnetic element, being arranged at the axial region place and disposing in pairs with the matrix magnetic element, the axis body magnetic element is to face mutually with same polarity with the matrix magnetic element.Wherein, when matrix and rotary body were positioned first stable state, the axis body magnetic element was positioned at a side of matrix magnetic element, and when matrix and rotary body were positioned second stable state, the axis body magnetic element was positioned at the opposite side of matrix magnetic element.

Concrete implementation content
This kind has the rotating mechanism of magnetic, comprised matrix (being mobile phone body 110 when being applied in cover-lifting type mobile phone) and rotary body (being flip 120 when being applied in cover-lifting type mobile phone).Please refer to Fig. 2 a, what it illustrated is the mobile phone body schematic diagram that is provided according to a preferred embodiment of the present invention.Mobile phone body 110 has fixed part 200.Then please refer to Fig. 2 b, what it illustrated is the flip schematic diagram that is provided according to a preferred embodiment of the present invention.Flip 120 has axial region 230, and fixed part 200 can make flip 120 with respect to mobile phone body 110 rotations when coupling with axial region 230.Then please refer to Fig. 2 c, what it illustrated is the schematic diagram of fixed part among Fig. 2 a.Fixed part 200 includes matrix magnetic element 210, is arranged at fixed part 200 places; And shaft hole 220.Then please refer to Fig. 2 d, what it illustrated is the schematic diagram of Fig. 2 b middle shaft part.Axial region 230 includes axis body magnetic element 231, is arranged at axial region 230 places and disposes in pairs with matrix magnetic element 210.Axial region 230 passed shaft hole 220 when assembling was finished, and flip 120 can be rotated with respect to mobile phone body 110.This moment, axis body magnetic element 231 was faced (for example be both the N utmost point or be both the S utmost point) with matrix magnetic element 210 mutually with same polarity, and in practical application, axis body magnetic element 231 can be magnet or electromagnet with matrix magnetic element 210.
Wherein, axis body magnetic element 231 and matrix magnetic element 210 can be mutually exclusive because of the principle that the magnetic same sex is repelled each other, and make axial region 230 to reach stable status up to running into obstruction with respect to shaft hole 220 to rotating clockwise or counterclockwise.With Fig. 2 c and Fig. 2 d is example, axial region 230 will rotate up to flip 110 in the counterclockwise direction because of the magnetic action that the same sex is repelled each other closes (first stable state) fully, or be rotated in a clockwise direction up to flip 110 unlatchings (second stable state), when mobile phone body 110 and flip 120 are positioned first stable state (closing), axis body magnetic element 231 is positioned at a side of matrix magnetic element 210, when mobile phone body 110 and flip 120 were positioned second stable state (unlatching), axis body magnetic element 231 was positioned at the opposite side of matrix magnetic element 210.
In the process that flip 120 is opened, the application of force need overcome the resistance that magnetic force causes, otherwise flip 120 will be got back to the situation of first stable state (closing).But after magnetic balanced point is passed through in the position of flip 120, flip 120 will be opened naturally because of magnetic force can produce the moment identical with direction of rotation.In like manner, in the process that flip 120 is closed, magnetic force also produces same function.
More than be main explanation of the present invention, but the design of axis body magnetic element 231 and matrix magnetic element 210 is not limited to single magnetic pole.Next please refer to Fig. 3 a, Fig. 3 b, Fig. 3 c and Fig. 3 d, what it illustrated is that Fig. 2 c and Fig. 2 d central axis magnetic element 231 are gone up the situation that changes with 210 designs of matrix magnetic element.As shown in the figure, axis body magnetic element 231 can be increased and decreased according to need with the magnetic number of matrix magnetic element 210, and the magnetic of adjacent magnetic must be opposite, is example with this figure, and magnetic 301,302 magnetic are opposite, and magnetic 303,304 magnetic are opposite; And magnetic 301,303 magnetic are identical, and magnetic 302,304 magnetic are identical.
The disclosed rotating mechanism with magnetic of the above embodiment of the present invention has the following advantages at least:
1. not easy to wear, and do not have to use the repeatedly problem of back elastic fatigue, make to prolong useful life.
Since the axle body that directly utilizes rotating mechanism as the mechanism of hinge function is arranged, more do not take up space than the hinge of traditional cam-spring (sheet) formula.
In sum; though disclosed the present invention in conjunction with an above preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art are not breaking away from the spirit and scope of the present invention; can do various changes and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
