Description

The armature apparatus structure

Technical field

The utility model relates to a kind of armature apparatus structure, refers to a kind of armature apparatus that is installed in the cover-lifting type electronic product especially, and the angular turn on a large scale of cover-lifting type electronic product lid can be provided.

Background technology

Along with making rapid progress of science and technology; electronic product; for example: mobile phone has become one of indispensable articles for use of people's daily life; the design of early stage mobile phone only has a key body; and in this key body be provided with the conversation hole; the user is behind FD finished dialing; directly seeing through the conversation hole talks; and after finishing using mobile phone is covered up; tradition has the mobile phone of key body; though can satisfy the demand that people carry; but because lack the setting of a lid; when people carry; cause dialing of mobile phone because of touch of key-press by accident easily; and the mobile phone that only has key body; also be subjected to dust easily; the influence of aqueous vapor and foreign matter and cause the damage of key body; so for improving the formed defective of above-mentioned key body mobile phone; just the someone has invented the folding type mobile phone; be also referred to as the folding type mobile phone; it is impaired to protect key body to avoid; the design of folding type lid henceforth also just progressively is applied to other above electronic product, the most common to be to be applied to electronic dictionary.

Electronic dictionary is that lid one is articulated in key body, and one armature apparatus is set in key body and lid articulated section, as shown in Figure 7, this armature apparatus, be to run through rotating shaft 30a, rotating shaft 40a, spring 50a respectively, and the head of axle 20a is embedded in lid 10a, be equipped with a cover plate 60a in the axle 20a other end again with an axle 20a, and the terminal riveted of axle 20a become a riveted end, in order to fixedly to be set in all members on all axle 20a.This moment, lid 10a and rotating shaft 30a can be fixed in fixed terminal one side of key body, and rotating shaft 40a then is positioning of rotating terminal one side who is fixed in lid.

When the electronic dictionary lid is raised, end face between rotating shaft 30a and the rotating shaft 40a, can make positioning of rotating by set jog 31a, 41a, and rotating shaft 30a can compress to rotating shaft 40a, the this moment and the spring 50a of rotating shaft 40a interaction, because of being subjected to the compression of rotating shaft 40a, can along axle 20a do parallel axes to compression displacement, and after rotating shaft 40a rotation finishes, elastic force by spring 50a itself, rotating shaft 40a is compressed in rotating shaft 30a in the other direction, both set jog 31a, 41a is fastened, to control the angle that its lid is raised.

Tradition armature apparatus structure, though can reach the purpose that the electronic dictionary lid is raised, but this kind execution mode, but lid can only be raised to 1 50 the degree about, surpass 150 degree and just cause rocking and not driving fit of body easily, make product reduce its texture and reliability, so the armature apparatus installed of conditional electronic dictionary, still there are some defectives in the use.

The utility model content

The utility model is in view of traditional armature apparatus structure, and when being installed in electronic dictionary, defective that is had in the use and restriction provide a kind of armature apparatus structure.

Main purpose of the present utility model is to provide a kind of armature apparatus structure, is the structure that will improve between inner rotating shaft of traditional armature apparatus and rotating shaft, when making armature apparatus be installed in the cover-lifting type electronic product, can increase the angle that cover-lifting type electronic product lid is raised.

To achieve these goals, the utility model provides a kind of armature apparatus structure, and it is installed in the main body and the lid of cover-lifting type electronic product, include a sleeve, this sleeve one end offers hole, and this cartridges sides is formed with opening, and this sleeve inner is placed with rotating shaft, rotating shaft and spring in regular turn; Be provided with axis hole and the axle center that is connected in series between this rotating shaft and the rotating shaft, be formed with an inner ring cam and an outer ring cam around this axis hole, and be formed with a projection and an outer projection in corresponding around this axle center;

By the lid of raising the cover-lifting type electronic product, drive is installed in the armature apparatus of cover-lifting type electronic product main body and lid articulated section, make formed interior projection of its sleeve inner rotating shaft and outer projection, rotate along formed inner ring cam of rotating shaft and outer ring cam edge, relend the elastic force that helps set spring in the sleeve, rotating shaft after rotating is fixed in rotating shaft, and the cover-lifting type electronic product is at closure state or be opened into 180 degree, all can locate.

In other words, the utility model includes a sleeve, sleeve one end offers hole, and be formed with opening in cartridges sides, sleeve inner is placed with rotating shaft, rotating shaft and spring in regular turn, be provided with axis hole and the axle center that is connected in series between rotating shaft and rotating shaft, and in axis hole be formed with corresponding two cams and projection around the axle center; By raising the cover-lifting type electronic product, can drive the armature apparatus that is installed in cover-lifting type electronic product main body and lid articulated section, make formed two projections of its sleeve inner rotating shaft, rotate along formed two cam edge of rotating shaft, relend the elastic force that helps set spring in the sleeve, rotating shaft after rotating is fixed in rotating shaft, allow the cover-lifting type electronic product be opened to 180 also can be certain when spending the location.

Therefore, the utility model has following advantage in design:

Armature apparatus of the present utility model is owing to be positioned over a sleeve inner with rotating shaft, rotating shaft and spring, and be provided with corresponding two cams and projection between rotating shaft and rotating shaft, therefore when the lid of raising the cover-lifting type electronic product, after two projections of rotating shaft finish along two cam rotation of rotating shaft, can be compressed in rotating shaft to rotating shaft in the other direction by the elastic force of spring, allow both set projections and cam fasten, the angle that makes cover-lifting type electronic product lid raise reaches 180 degree.Moreover the lid after raising also can be by the design of two inside and outside circle cams and is obtained certain location.
