Abstract

The utility model relates to a junction device which comprises a body support connected with a laptop body. The body support is provided with a pivot. A screen staddle is pivoted on the pivot and is connected with a screen, and the pivot is additionally sheathed with a compression component. The compression component consists of a dynamic tab and a static tab, the dynamic tab is provided with at least a concave face that is formed by gradually invaginating from the plane; the static tab is blocked and sheathed on the pivot, and a bump corresponding to the concave face are arranged on the surface of the static tab. As the dynamic tab and the static tab on the compression component are provided with the concave face and the bump matched with each other, the junction device is provided with different frictions respectively when the screen corresponding to the body is in a state from close to open , thus leading the screen to be opened easily and preventing the screen from falling off during the closing process.

Description

Pivot device

Technical field

The utility model is a kind of pivot device, and it can pivot by corresponding body to make screen in order between the screen and body that are arranged at laptop computer.

Background technology

Pivot device generally is arranged between the loam cake and body of lid opening device (for example laptop computer), make the loam cake of lid opening device open and closed device as one with respect to body, yet most of pivot device of prior art is between the stroke that pivots, its pivot device is all unanimity in the frictional force of pivotal action, therefore when the user when lid opening device is opened, may feel that breakdown action is very painstaking because of the weight of loam cake, and when wanting closed loam cake, also may knock body in order to prevent the loam cake landing, therefore must further impose the power of a bracketing to prevent loam cake landing excessive velocities, and when opening closed loam cake, should be noted that the control of power, in this operation for the user, can say so has increased meaningless puzzlement.

The utility model content

Because aforesaid the deficiencies in the prior art point, the design of the utility model system is a kind of to be located between the screen and body of laptop computer, has differentiated friction power between pivotal action, allowing screen be easy to open, and is difficult for the pivot device of landing when closed.

For achieving the above object, the technological means that the utility model adopted is a kind of pivot device of design, and it comprises:

One body connects frame, and its outboard end is provided with fixed part, and the end extension is provided with a pivot in addition, and has the body of rod of non-circular section;

One screen bolster runs through forming the pivot hole and being sheathed on the body of rod of pivot pivotly on it, and this screen bolster radially extends outwardly from pivot end and forms fixed part;

One compressing assembly, its a plurality of lamellar bodies by consecutive are formed, and are sheathed on the pivot, and against also pushing tow is in the inboard of screen bolster, the compressing assembly comprises a moving trimmer and a quiet trimmer; Moving trimmer is provided with a pivot hole and articulates and is sheathed on the pivot, it is connected in the screen bolster, the medial surface of moving trimmer is provided with at least one concave surface, it is from the recessed gradually moulding in this place, surperficial plane and become to be distributed in radially this surface, and more be provided with a plurality of continuous steps on the face of slope of concave surface, the joint face between step and step is tilt distribution; Run through the blocking hole and the blocked sleeve that are provided with section cooperation pivot on the quiet trimmer and be located at pivot, quiet trimmer outer surface is provided with the projection of corresponding concave surface, and projection optionally carries over and is displaced on the concave surface.

Dynamic and static trimmer in the mat compressing assembly is provided with concave surface and the projection that matches, can make pivot device be between the state that is closed to unlatching respectively at the corresponding body of screen, spin friction power increases to maximum gradually from minimum respectively, so allowing screen open easily, and can prevent screen landing in closed action.

Embodiment

Please referring to Fig. 1 to shown in Figure 3, pivot device 1 wherein of the present utility model is located at 90 of the screen 80 of laptop computer and bodies, it can further comprise a body and connect frame 10, a screen bolster 20 and a compressing assembly 30.

The outboard end that aforesaid body connects frame 10 is provided with fixed part, and mat its be fixed in the body 90 of laptop computer, the in addition end that body connects frame 10 extends and is provided with a pivot 11, these pivot 11 elongated end places are provided with screw thread 12, and have the body of rod of non-circular section.

Please further cooperate referring to shown in Fig. 4 and 5, run through on the aforesaid screen bolster 20 and form pivot hole 21, and mat pivot hole 21 is sheathed on the shaft of pivot 11 pivotly, and this screen bolster 20 radially extends outwardly from pivot end and forms fixed part 22, its correspondence is fixedly connected on screen 80 and can pivots by corresponding body 90 to make screen 80, and the extension support body of screen bolster 20 is provided with a location hole 23.

Aforesaid compressing assembly 30 can be a series of a plurality of lamellar body and forms, it is sheathed on the elongated end of pivot 11, against and pushing tow in the inboard of screen bolster 20, with make screen bolster 20 be close proximity to body connect frame 10 and and then both are provided the frictional force between pivotal action, compressing assembly 30 can further include a packing ring 31, one moving trimmer 32, one quiet trimmer 33, a pad 34, a shell fragment 35, a pad 36 and a fixture 37;

Its middle washer 31 is provided with the blocking hole 311 of corresponding pivot 12 external forms and sheathed by this being equipped on the pivot 12 in central authorities;

Please further cooperate referring to shown in Figure 6, wherein moving trimmer 32 is provided with a pivot hole 321, and pivot joint is sheathed on the pivot 11 thus, and be extended with a reference column 322 in a side place, its correspondence wears in the location hole 23 that is fixed in screen bolster 20 to make trimmer 32 and screen bolster 20 be the continuous action relation of corotation, and be provided with the concave surface 323 of at least one arcuation in the medial surface of moving trimmer 32, recessed gradually moulding also becomes to be distributed in radially this surface from the place, plane for it, and more be provided with a plurality of continuous steps 324 on the face of slope of concave surface 323,325, the joint face that step 324 and step are 325 is tilt distribution;

Please further cooperate referring to Fig. 7 and shown in Figure 8, run through on the wherein quiet trimmer 33 and be provided with the blocking hole 331 that a section cooperates pivot 11 external forms, and these blocking hole 331 blocked sleeves of mat are located at pivot 11 to present the continuous action relation of corotation with it, the lateral surface pushing tow of quiet trimmer 33 is in the medial surface of moving trimmer 32, and the projection 332 that should the surface be provided with corresponding concave surface 323, this projection 332 can be the block that two sides tilt and present the plane in the top, and projection 332 correspondences rely on the innermost step 324 of concave surface 323 when screen 80 corresponding bodies 90 are closure, therefore the friction stree on surface is minimum, and work as in screen 80 unlatchings, then projection 332 carry over move on concave surface 323 domatic and and then be resisted against on the step 325, and because of with gradually high step 325 surfaces mutually compressing make frictional force increase (please cooperate referring to Fig. 9 extremely shown in Figure 11) gradually;

Its Intermediate gasket 34 protecting this wall preventing wearing and tearing, and can sheathedly be equipped on the pivot 11 by the interior sidewall surface of being located at quiet trimmer 33;
