Abstract

The utility model relates to a motion mechanism of a motion body along with a guide rail. The guide rail of the mechanism is made of opening pipe components; spheres with arms are arranged in the guide rail, and the centers of the spheres are provided with holes and are in series into a ball chain; arms of the spheres with arms extend out of the guide rail and are connected with the motion body; when the ball chain is affected, the motion is transmitted to the motion body to enable the motion body to realize the motion along with the defined track of the guide rail.

Description

A kind of movable body is along guide rail movement mechanism

The utility model relates to a kind of movable body along guide rail movement mechanism, still its be movable body by the ball chain in guide rail, move realize along guide rail movement mechanism.

Common movable body has roller along guide rail movement along guide rail movement mechanism, as the motion of train wheel on rail; With moving body along the moving of dovetail furrow, as " head " moving in dovetail furrow of lathe.Roller can do movement in a curve, but guide rail can not limit up beating of roller during along guide rail movement; The movable body that moves in dovetail furrow is subjected to about the dovetail furrow, about spacing, but can only moving linearly, can not movement in a curve.The purpose of this utility model provides a kind of movable body along guide rail movement mechanism, when it makes movable body along guide rail movement, up and down, about mobilely obtain spacingly, simultaneously can do movement in a curve again.

The purpose of this utility model is achieved in that design one mechanism, and mechanism is made up of guide rail, band arm spheroid, draught line, movable body.Wherein, guide rail is used along the tubing of axis opening and is made, and the cross section shape of tubing is opening circle or opening polygon; The ball centre of band arm spheroid is porose, and along with the axially bored line vertical direction arm being arranged, arm is cylinder or polygon cylinder.The assembling and the working process of mechanism are as follows: with draught line a plurality of band arm spheroids are linked to be the ball chain: draught line passes the centre hole of each band arm spheroid, and tightly be one with certain fixed form and band arm spheroid, make when draught line moves that band arm spheroid and then moves.To place guide rail with arm spheroid chain: the spheroid of each band arm spheroid partly is in the guide rail cavity, and arm is in outside the guide rail by the opening of guide rail.Guide rail is made camber line or rectilinear form according to the required path of motion of movable body.Movable body links to each other with band arm spheroid chain by the arm of band arm spheroid, when draught line drive band arm spheroid chain moves in guide rail, movable body and then is with arm spheroid chain to move together, because the spheroid of band arm spheroid partly is limited in can not moving up and down in the guide rail cavity, can only be along the rail axis translation, and on left and right directions and guide openings face, do certain rotation, thereby when realizing that movable body is along guide rail movement, up and down, about mobilely obtain spacingly, can do movement in a curve again simultaneously.

Owing to adopt such scheme, can realization movable body easily about, about mobile being defined, can do again movement in a curve along guide rail movement.

Below in conjunction with drawings and Examples the utility model is further specified.

Figure--the-1st, the utility model is used for movable body must could satisfy the example structure figure that functions of use requires along the guide rail movement in a curve.

Figure--the-2nd, figure---1 profile.

Among the figure, 1, guide rail 2, band arm spheroid 3, draught line 4, movable body (sunshade band) 5, motor 6, front screen 7, car ceiling 8, guide rail fixed mount 9, Che Bi

At figure--in-1, movable body (4) is the small passenger car front screen sunshade band of being made by retractable material, can all close at the car ceiling during by not sunshade of designing requirement, goes out from ceiling along the guide rail translation during sunshade, partly or entirely the car front screen is covered.Because the front screen of car is generally echelon form, movable body (4) must be done movement in a curve in the space in motion process.General guide rail drive mechanism, the space of leaving mounting guide rail (1) because of small passenger car front screen place for is minimum, is difficult to perfectly reach above-mentioned effect.Adopt the utility model, with the minimum tubing of section size, the camber line that forms by small passenger car front screen two edge and small passenger car roof two edges line is made the guide rail (1) of space camber shape, just can well realize above-mentioned motion requirement to sunshade band-----movable body (4).During transmission, motor (5) drives draught line (3), draught line (3) drives the band arm spheroid (2) of chaining, band arm spheroid (2) drives sunshade band--movable body (4), thereby realize that the sunshade band---movable body (4) is done required space movement in a curve along guide rail (1), in the intermarginal translation up and down of small passenger car front screen, finish the sunshade process.In the above-mentioned motion process, in the tapped bore of being opened on band arm spheroid (2) that communicates with centre hole, screwing in sunk serew, draught line (3) and band arm spheroid (2) are clamped is one.Thereby band arm spheroid (2) can be affected when realizing draught line (3) motion.

When the utility model is used for curtain along the guide rail movement structure, also can realize very easily garden arc formula balcony, door and window curtain along movement in a curve.

Claims

1, a kind of movable body is along guide rail movement mechanism, it is characterized in that: mechanism is made up of guide rail (1), band arm spheroid (2), draught line (3), movable body (4), wherein, guide rail (1) is by making along the tubing of axis opening, the ball centre of band arm spheroid (2) is porose, along on the direction vertical with axially bored line arm being arranged; The assembling of mechanism and working process are: a plurality of band arm spheroids (2) are placed in the guide rail (1): the spheroid of band arm spheroid (2) is in the tube chamber of guide rail (1), and the quilt of band arm spheroid (2) is stretched in outside the guide rail (1) by the opening of guide rail (1); Simultaneously, draught line (3) passes the hole on each band arm spheroid (2), and tightly is integral by certain fixed form and band arm spheroid (2), forms the ball chain, and movable body (4) links to each other with the arm of band arm spheroid (2); When making draught line (3) motion, band arm spheroid (2) and then moves along guide rail (1), and movable body (4) is passed in motion, makes the motion of movable body (4) realization along guide rail (1).

2, movable body according to claim 1 is characterized in that along guide rail movement mechanism: the cross section shape of guide rail (1) is opening circle or opening polygon.

3, movable body according to claim 1 is characterized in that along guide rail movement mechanism: the extension arm of band arm spheroid (2) is cylinder or other polygon cylinder.
