Abstract

The invention relates to pivotal institutions, which is located in an electronic device noumenon. This pivotal institution includes a fixing part and a rotating part. The fixing part is fixed in the noumenon and it has a socket, the socket surface is a melody surface. The rotating part is embedded in the slot to make interference. When rotate these rotating parts, the melody surface of fixing part interferes and has an extrusion to the rotating part, which can make the rotating parts to produce a translation.

Description

Electronic installation and hinge mechanism thereof

Technical field

The relevant a kind of hinge mechanism of the present invention, and particularly relevant a kind of hinge mechanism that is applied in the electronic installation.

Background technology

Please refer to Fig. 1, Fig. 1 is a hinge mechanism stereogram in the traditional electronic devices.In electronic installation, for example be the flip of a mobile phone, the hinge mechanism 100 of flip comprises: a fixture 103, a revolving part 105 and a spring 107.Revolving part 105 is to curl up fixture 103 to be rotated.When Y direction rotation revolving part 105, also can produce the stroke of directions X simultaneously.Therefore, configuration spring 107 can automatically reply revolving part 105 to the equilbrium position.By the rotation or the translation of directions X Y and direction, the action that flip also can be rotated or move.

Yet present fixture 103, revolving part 105 and spring 107 are mostly to be metalwork.For example mobile phone, personal digital assistant etc. can be sent in many electronic installations or received RF signal (Radio FrequencySignal) to operate.Because in the hinge mechanism, metal material own can disturb radiofrequency signal, and then influences the overall performance (Performance) of electronic installation.In addition, also because unitary construction is comparatively complicated, the fraction defective of product is increased.

Summary of the invention

In view of this, the purpose of this invention is to provide a kind of hinge mechanism of electronic installation, can not influence the normal operation of radiofrequency signal, and simplify the overall structure of electronic installation simultaneously because of spring, fixture and the revolving part of metal.

According to purpose of the present invention, a kind of hinge mechanism is proposed, it is arranged in the body of an electronic installation, and hinge mechanism comprises: a fixture and a revolving part.Fixture is fixed in the body, and fixture has a groove, and the surface of groove is an irregular curved surface.Revolving part is made interference engagement in order to be embedded in groove.Wherein when the rotation revolving part, the curved surface of fixture is interfered the extruding revolving part, makes revolving part produce translation.

According to purpose of the present invention, reintroduce a kind of electronic installation, comprising: a body and a hinge mechanism.Hinge mechanism is arranged in the body, and hinge mechanism comprises: a fixture and a revolving part.Fixture is fixed in the body, and fixture has a groove, and the surface of groove is an irregular curved surface.Revolving part is made interference engagement in order to be embedded in groove.Wherein when the rotation revolving part, the curved surface of fixture is interfered the extruding revolving part, makes revolving part produce translation.

For the present invention's above-mentioned purpose, characteristics and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. is elaborated as follows:

Embodiment

Please refer to Fig. 2 A, Fig. 2 A is the electronic installation stereogram.Electronic installation for example is a mobile phone.Shown in Fig. 2 A, electronic installation 200 comprises a body 201 and a hinge mechanism 202.By the configuration of hinge mechanism 202, the casing 204 that can drive electronic installation 200 is rotated with respect to electronic installation 200.Hinge mechanism 202 comprises fixture 203 and revolving part 205 (shown in Fig. 2 E).By following execution mode, the fixedly angle of revolving part rotation and mobile stroke thereof replacing the hinge mechanism (as shown in Figure 1) that utilized revolving part, fixture and spring to be formed in the past, and can be applied to this hinge mechanism in the different electronic installations.

Please be simultaneously with reference to Fig. 2 B and Fig. 2 C, Fig. 2 B is the fixture profile, Fig. 2 C is a fixture section configuration schematic diagram.In fixture 203, has a groove 209.The surface of groove 209 is irregular curved surfaces.Simultaneously, fixture 203 comprises at least one location division, for example is the first location division 210a and one second location division 210b.The first location division 210a for example is a recess.The second location division 210b for example is the other recess of protuberance, to assist position rotating part 205 (as Fig. 2 D).And fixture 203 itself is that a sleeve (Bushing) is with ccontaining revolving part 205.

Please refer to Fig. 2 D, Fig. 2 D is the revolving part profile.Revolving part 205 comprises a hollow bulb 211 and at least one holding section 213.Hollow bulb 211 has enough deformation spaces (the inwardly space of compression) in order to revolving part 205 to be provided, and therefore when revolving part 205 pressurizeds, revolving part 205 is able to by hollow bulb 211 to internal strain.

Please refer to Fig. 2 E, Fig. 2 E is that the hinge mechanism start concerns schematic diagram.Revolving part 205 is embedded in the groove 209, because the section width of revolving part 205 and groove 209 is basic identical, therefore when rotating revolving part 205 (as the direction of A1), 203 of revolving part 205 and fixtures can produce interference, and just fixture 203 can inwardly compress revolving part 205.If be a level and smooth plane on the fixture 203, only have the stroke (Y directional run) of rotation when then rotating revolving part 205.And be exactly owing to have an irregular curved surface on the fixture 203, therefore when rotating revolving part 205, fixture 203 can extruding interfere revolving part 205 to go to rotate along the irregular curved surface of fixture 203.And irregular curved surface be around and extend groove 209 surfaces, so revolving part 205 can produce the stroke of directions Xs.

Shown in Fig. 2 E, for example be the initial position of directions X stroke along directions X B1 position, the B2 position is the last position of directions X stroke.Offer the first location division 210a on the initial position B1 of fixture 203, and the last position B2 of fixture 203 offers the second location division 210b, so holding section 213 can correspondence be sticked on the first location division 210a and the second location division 210b.Therefore electronic installation 200 for example mobile phone (shown in Fig. 2 A) can corresponding location turn to the position at θ angle.Certainly, also can offer more location division on the irregular curved surface, to increase more rotational positioning part.

The described hinge mechanism of the foregoing description can be applied mechanically to different electronic installations, for example mobile phone, personal digital assistant, notebook computer and LCD etc.Because hinge mechanism only needs revolving part and fixture and does not need spring, can be rotated and the action of translation, simplified structure not only, the nonmetallic structures of elastomer such as while plastic material more need not worry to disturb the electronic installation of radiofrequency signal, and then influence the quality of electronic product, particularly mobile phone etc. needs the electronic product of high-frequency signal, more can guarantee the quality of electronic product.

In sum; though the present invention discloses as above with a preferred embodiment; yet it is not in order to limit the present invention; any person skilled in the art person without departing from the spirit and scope of the present invention; when the variation that can make various equivalences or replacement, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
