Description

Auxiliary sliding members

The utility model relates to a kind of auxiliary sliding members, but uses between two members of relative motion, particularly a kind of auxiliary sliding members in order to reduce friction resistance and to keep two members to contact lastingly.

The purpose of mechanism design is to change the structure of existing product, so that renewal to be provided, the better product more easily that reaches, this is a direction of being engaged in R﹠D work person at present, for instance, host computer inside in the past is made up of many circuit boards, these circuit boards are locked in computer chassis usually, if get a certain circuit board, then needing to dismantle the element of many peripheries and many screws could take out circuit board maintenance or change, certainly this problem usually occurs in the main circuit board of computer system, and in order to address this problem, so there is manufacturer computer to develop a kind of new combination, motherboard is placed on the frame, design has slide rail on the frame, and the mode that design has track, frame can move slip in computer chassis is pushed in the track and be incorporated in the computer chassis, finishes the assembling operation of motherboard; If during same desire maintenance motherboard, frame directly can be pulled out, can keep in repair or change motherboard, such design will significantly improve the speed of assembling, and the convenience of maintenance in the future.Be example again with the notebook computer, notebook computer has comprised main frame and two parts of display haply, wherein main frame is provided with a keyboard, with device as user's input, keyboard in the past is directly to be fixedly arranged on the main frame, yet sometimes for fear of the volume and the operating space of main frame, it is very not convenient in operation that keyboard is fixedly arranged on the main frame, for head it off, so being arranged, manufacturer computer develops a kind of new combination, promptly be slidably to be incorporated into keyboard in the main frame, keyboard can be accommodated in the main frame when not using, then can be during use with keyboard by pulling out in the main frame, such design also can be satisfied part user's demand.

Above-mentioned example all is to utilize the engagement means that slides to make up two members, and the engagement means of the slip of adopting at present is movable part to be limited to move in the fixed range, or be the matching way that utilizes slide rail and slideway, that is on a member, design slide rail, another member then designs slideway, directly be incorporated on the slideway by slide rail in mobilizable mode, frictional resistance is bigger yet the mode of direct friction is bound to, the wearing and tearing that produced are also bigger, and many structures are to adopt plastics at present, wearing and tearing or distortion can take place in the slide rail of plastics and slideway in use for some time, because of different sound takes place in the process of sliding matching error, then can making sometimes slides has some setbacks sometimes.

Moreover, the relation that electric connection will be arranged to each other as two members, for example adopt the slidably notebook computer of keyboard, wherein between keyboard and main frame the formation electrical connection must be arranged, in design in the past, be that design has metallic laminas on the slideway of main frame, and contact the electric connection that constitutes between keyboard and main frame with the metal slide plate by the slide rail on the keyboard, yet as previously mentioned, over time, if slideway wearing and tearing or distortion produce error, then may make electrically connecting that slide rail can't be certain, cause the loose contact between keyboard and main frame, maybe can't use with metallic laminas.

But the utility model fundamental purpose is to provide the auxiliary sliding members between two members that are arranged at relative motion, particularly a kind of auxiliary sliding members in order to reduce friction resistance and to keep two members to contact lastingly.

According to auxiliary sliding members provided by the utility model, formed by a sleeve, two balls and elastic component, wherein ball is to place in the sleeve, elastic component is then between up and down between two balls, elasticity by elastic component makes two balls maintenance up and down protrude in two ends of sleeve, to assist sliding members to be arranged between two members, when making two member relative motions by the ball resistance of reducing friction, and the elasticity by elastic component makes up and down that two balls contact with two members lastingly, keeps the contact relation of two members.

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, so that further understand above-mentioned and other purposes, feature and advantage of the present utility model.

perforation

1131,1141; Therefore second cylindrical shell 12 also is cylindric that hollow runs through, and two ends constitute upper shed 121 and under shed 122 respectively, and wherein second cylindrical shell, 12 external diameters just equal the internal diameter of first cylindrical shell 11, and first cylindrical shell 11 can be nested with and be incorporated on second cylindrical shell 12 and constitute sleeve 10.

Ball

20,30 is a metal ball body up and down, its sphere diameter must be less than the internal diameter of first cylindrical shell 11 and second cylindrical shell 12, but need be slightly larger than the aperture of the under shed 122 of the upper shed 111 of first cylindrical shell 11 and second cylindrical shell 12,

ball

20,30 can be placed respectively in first cylindrical shell 11 and second cylindrical shell 12, and unlikelyly drop out, but have 1/4th spheroid can protrude in the upper shed 111 of first cylindrical shell 11 and the under shed 122 of second cylindrical shell 12 approximately from the upper shed 111 of first cylindrical shell 11 and the under shed 122 of second cylindrical shell 12; And elastic component 40 is a spring and between 20,30 on two balls, make two balls, 20,30 normalities keep protruding in two ends of sleeve 10 by the elasticity of elastic component 40, and two

balls

20,30 still can roll in sleeve 10.

See also shown in Fig. 4 A, the 4B, shown in the figure embodiment of the present utility model, but the disclosed auxiliary sliding members of the utility model is arranged between two members of relative motion, first member 50 (can be the host machine part of notebook computer) has an accommodation space 51 at least, second member 60 (can be the extraction-type keyboard of notebook computer) then is arranged in the accommodation space 51 of first member 50 movably to concern, make second member 60 have a stowed position that is accommodated in fully in the accommodation space 51 at least, and shift out in the use location of accommodation space 51; Its middle sleeve 10 is arranged on second member 60, utilize the fin 113,114 of sleeve 10 to be cross-placed on the appropriate location of second member 60, the

perforation

1131,1141 of passing through fin 113,114 with screw 70 binding members such as grade, sleeve 10 is fixed on second member 60, the length of sleeve 10 slightly equals the thickness of second member 60, makes the ball up and down 20,30 of two ends in the sleeve 10 protrude in two sides up and down of second member 60; Certainly on second member 60, several auxiliary sliding members can be set, second member 60 promptly utilizes several auxiliary sliding members to contact with the last lower wall surface of the accommodation space 51 of first member 50, when second member 60 moves, by ball 20 up and down, 30 rolling, the resistance of can reducing friction, make motion process more smooth and easy, and the elasticity by elastic component 40 makes ball 20 about in the of two, 30 contact with the last lower wall surface of accommodation space 51 lastingly, keep contact relation with first member 50, even

first member

50 and 60 some errors of second member also can make ball 20 by the elasticity of
