Abstract
The utility model relates to a hinge mechanism for connecting a host computer and a liquid crystal display of a notebook computer. A stop friction pad contacts a shaft shoulder surface of a rotary shaft, and an internal circle of the stop friction pad is provided with a bulge. The shaft of the rotary shaft matching the stop friction pad is provided with a groove, and the bulge on the stop friction pad can match the groove. The stop friction pad and the rotary shaft can not relatively move for preventing the abrasion of the shaft shoulder surface. One side surface of all friction pads is provided with a plurality of arc-shaped grooves which are arranged in the direction of the internal circle for increasing the storage of lubricant. When the friction pads mutually rotate, the fluidity of the lubricant can be increased for decreasing the abrasion of the friction pads and the lubricant.
Description
Technical field
The utility model is a kind of hinge arrangement, is mainly used in the connection between notebook computer main frame and the LCD.
Background technology
The common usefulness of connection between notebook computer main frame and the LCD be hinge arrangement, comprise a rotating shaft, one bracing frame, one location-plate, one locknut, several pads that rub, several dish-type pads, the pad that wherein rubs is provided with the aperture of a plurality of circles, and these circular apertures become a round arrangement along the direction of interior circle.The combination step of each inter-module is: 1. put two friction pads 2. cover upper support frames 3. and put two friction pads 4. and put several dish-type pads 5. and put location-plate 6. and tighten locknut in rotating shaft, each assembly just closely cooperates together like this.Wherein location-plate and locknut are fixed with respect to rotating shaft, each pad that rubs, and each dish-type pad all can relatively rotate between rotating shaft and the bracing frame.
Owing to there is one to contact in set up two frictions of the first step pads with rotating shaft shaft shoulder face, again owing to can relatively rotate between this friction pad and the rotating shaft, so the time one is long, the rotating shaft shaft shoulder severity of will wearing and tearing, make between each assembly in conjunction with not tight, moment of torsion became big when this hinge used, and was easy to damage.
Because each friction can relatively rotate between pad, lubricate so need add some sliding agents, the aperture on the friction pad is used for kind of lubricant storage, and aperture is very little, so the amounts of lubrication that stores is seldom, and when rotating, sliding agent flowability in the aperture is very poor, and lubricant effect is bad.
Summary of the invention
The main purpose of the utility model provides a kind of hinge arrangement, prevent the wearing and tearing of rotating shaft shaft shoulder face by stop friction pad, this stop friction pad and rotating shaft shaft shoulder face contact, in the interior circle of stop friction pad a projection is arranged, on the axle that rotating shaft and stop friction pad matches, be provided with a groove, the projection on the stop friction pad can be matched with groove, stop rubs and does not relatively rotate between pad and rotating shaft like this, thereby prevents the wearing and tearing of rotating shaft shaft shoulder face.
Another main purpose of the utility model provides a kind of hinge arrangement, promote to lubricate by deep-slotted chip breaker, wearing and tearing between pad reduce friction, it is to be provided with several deep-slotted chip breakers on a side of all friction pads, these deep-slotted chip breakers are arranged along the direction of interior circle, increasing the memory space of sliding agent, and increase the flowability of sliding agent when rotating mutually between the friction pad, reduce wearing and tearing between the two.
Description of drawings
Be described in further detail below in conjunction with most preferred embodiment and accompanying drawing new structure this creation apsacline hinge.
Fig. 1 is a decomposition view;
Dyanainic friction pad zoomed-in view till Fig. 2;
Fig. 3 is the rotating shaft zoomed-in view;
Fig. 4 is friction pad zoomed-in view;
Fig. 5 is an assembled view.
The specific embodiment
As shown in Figure 1, one rotating shaft 1 is arranged in this utility model, one bracing frame 4, one location-plate 6, one locknut 7,3, four dish-type pads 5 of one stop friction pad 2, three frictions pad, the combination step of each inter-module is: (1) puts stop friction pad 2 in rotating shaft, put a friction pad 3, (2) cover upper support frame 4, (3) put two friction pads 3, (4) put four dish-type pads 5, (5) put location-plate 6, (6) tighten locknut 7, and each assembly just closely cooperates together (as shown in Figure 5) like this, wherein do not relatively rotate between location-plate and locknut and stop friction pad and rotating shaft, each pad that rubs, each dish-type pad all can relatively rotate between rotating shaft and the bracing frame.As Fig. 2, shown in Figure 3, in the interior circle of stop friction pad 2 projection 21 is arranged, on the axle that rotating shaft 1 and stop friction pad 2 matches, one groove 11 is arranged, and the width of groove 11 is slightly larger than or equals the width of stop friction pad 2 upper process 21, and the projection 21 on the stop friction pad 2 can be matched with groove 11, stop friction pad 2 and rotating shaft 1 just can not be rotated mutually like this, make the shaft shoulder face of rotating shaft 1 be unlikely frayed.
As Fig. 2, shown in Figure 4, be equipped with several deep-slotted chip breakers 22 on one side of stop friction pad 2 and all friction pads 3, these deep-slotted chip breakers 22 are arranged along the direction of interior circle, mainly be present in the position that rotating shaft 1 and location-plate 6 match owing to rotate friction, Gu the direction that the side that each friction pad 3 contains deep-slotted chip breaker all matches facing to location-plate 6 and rotating shaft 1, the capacity of deep-slotted chip breaker 22 is bigger, increased the memory space of sliding agent, because deep-slotted chip breaker 22 is arranged along the direction of interior circle, when the friction pad rotates, sliding agent in the deep-slotted chip breaker 22 also just flows along with the rotation of friction pad, increase the flowability of sliding agent when rotating mutually between the friction pad, reduced the wearing and tearing between two contact surfaces.
Certainly, the individual number average of friction pad of the above and dish-type pad not thing is fixing, decide according to situation.
Above-mentioned creation only illustrates with most preferred embodiment, and to being familiar with the personnel of this skill, when carrying out various variation examples, only these change example, all should be included in the spirit and scope of this creation.
