Abstract

The utility model discloses a flip hinge of a hand electronic terminal product, which comprises a fixed shaft, a sliding part and a rotating part which are coaxial with the fixed shaft, and a spring acting on the sliding part, wherein one of the sliding part and the rotating part is provided with a first cam surface and a second surface on the surface opposite to the other one, the first cam surface and the second cam surface are respectively arranged on two concentric circular rings; the other one of the sliding part and the rotating part is provided with a first contact part contacting with the first cam surface and is also provided with a second contact surface contacting with the second cam surface. The effective rotation angle of the utility model can be equal to or more than 180 degrees, thereby the function of opening the flip phone by 180 degrees is realized; moreover, the double-point contact supporting of the sliding part and the rotating part can be further realized.

Description

The hand held electronic terminals product renovate hinge

Technical field

The utility model relates to the hinge of renovating of hand held electronic terminals product.

Background technology

Has the electronic product of renovating at present, such as electronic products such as mobile phones, its semi-automatic rotation of renovating realizes by renovating hinge, it is renovated hinge and generally comprises fixed axis, rotating shaft, axle bed, axle bed is limited in the outer container and slidably, be provided with spring between axle bed and outer container, rotating shaft is arranged on the opposite side of axle bed, and fixed axis passes rotating shaft, axle bed and is connected the opposite side of outer container.Present renovate the actual rotations that can carry out 360 degree of hinge, but owing to cam surface cooperates the effective anglec of rotation that needs after two point contact, reality are installed can only be 180 degree, consider casing in the closed and hinge power that need provide support when opening, the effective anglec of rotation of actual hinge is generally 155 degree～165 degree.Thus, renovate handheld device when opening, lid is upturned, and influenced by external force and damages.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of can making and renovates the actual hinge of renovating of opening the 180 hand held electronic terminals products of spending.For this reason, the utility model is by the following technical solutions: it comprises fixed axis, coaxial sliding part and rotating part in fixed axis, acts on the spring of sliding part, in described sliding part and the rotating part one of them is being provided with first cam surface and second cam surface in the face of on another the surface, and described first cam surface and second cam surface are located at respectively on two donuts;

In described sliding part and the rotating part another is provided with first contact site that contacts with first cam surface, and another in institute's sliding part and the rotating part also is provided with second contact site that contacts with second cam surface.

Owing to adopt the technical solution of the utility model, the contact surface of the utility model sliding part and rotating part is in two donuts, cam curve on each annulus can adopt unsymmetric structure, can make rotating shaft install effective anglec of rotation greater than 180 degree, after deducting the precompressed angle of the power of providing support, the effective anglec of rotation of actual hinge can be equal to or greater than 180 degree, thereby realize the function that folding cell phone 180 degree are opened, and, can realize further that on this basis the two point of sliding part and rotating part contacts support.

Embodiment

With reference to accompanying drawing.The utility model comprises fixed axis 6, coaxial sliding part 4 and rotating part 5 in fixed axis, acts on the spring 3 of sliding part, described sliding part is being provided with first cam surface 41 and second cam surface 42 in the face of on the surface of rotating part, and described first cam surface and second cam surface are located at respectively on two donuts;

Described rotating part is provided with first contact site 51 that contacts with first cam surface and second contact site 52 that contacts with second cam surface can be formed by cam surface, also can be substituted by members such as projection, slide mass, rolling elements respectively.

Described hinge also comprises outer container 2, described fixed axis 6 pass rotating part 5, sliding part 4, spring 3 successively and outside the bottom surface of outer container 2 with metallic gasket 1 riveted joint.

Sliding part 4 is limited and can not rotate by relative fixed axle 6, and described spring 3 is between outer container and the described sliding part 4.

With reference to Fig. 7,

cam surface

41 and 42 path length surpass half of circumferential length of annulus of living in, and do not have the cam surface symmetrical with it on residing annulus.Its actual effective exercise track scope is greater than 180 degree, deduct the precompressed angle of the power of providing support after, the effective anglec of rotation of actual hinge can be equal to or greater than 180 degree, thereby realizes the function that folding cell phone 180 degree are opened.With reference to Fig. 6, cam surface curve on the sliding part was an axially symmetric structure in the past, repeated 2 identical cam surfaces in a circumferential direction, and its effective exercise track scope equals 180 degree, after deducting the precompressed angle of the power of providing support, the effective anglec of rotation of actual hinge is less than 180 degree.

In the enforcement, it is consistent that first cam surface and second cam surface can be made curve shape, but at circumferencial direction dislocation 180 degree.

First contact site and second contact site misplace in a circumferential direction 180 the degree.

In fact, even above-mentioned dislocation is not 180 degree, can realize that also the firm of sliding part and rotating part contacts support, but from symmetry and the best angle of implementing, 180 degree misplace preferably.
