Abstract
The utility model provides a sliding device for a sliding rail of an automobile chair, which belong to the technical field of machinery. The utility model solves the technical problem of nonuniform stress points between rolling balls and a sliding rail and between the rolling ball and a fixed rail of the sliding device of the existing chair sliding rail. The sliding device for the sliding rail of the automobile chair comprises a fixed rail and a sliding rail, wherein the sliding rail passes through the fixed rail and can slide in the fixed slide rail, a plurality of rolling balls are arranged between the fixed rail and the sliding rail, the rolling balls are in three-point contact with the fixed rail and the slide rail, and in addition, every two contact points have the same distance. The utility model has the advantages of uniform stress, smooth sliding, labor saving operation and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the carriage of a kind of carriage, particularly a kind of sliding rail of automobile seat.
Background technology
At present, seat will design to such an extent that chaufeur or passenger are taken is very comfortable, the seat of driver's seat and co-pilot seat can move forward and backward, chaufeur particularly, can regulate the position of seat according to the bodily form of self, can be sitting in the posture of the most comfortable on the seat to ensure, handle operator platform easily or control pedal.
At present, the carriage of the general sliding rail of automobile seat that adopts, generally comprise: a trapped orbit that is fixed on the U-shaped like on the vehicle floor, with a similar inverted U-shaped sliding rail that is fixed in seat bottom, described sliding rail and trapped orbit are meshing with each other, form each ball road of one group up and down, several rigidity balls of assembly slide sliding rail form with a contact in trapped orbit as rolling support component respectively in described four ball road.
Stress point between the ball of carriage and sliding rail and the trapped orbit is inhomogeneous like this, and the resistance that ball is subjected in sliding process is bigger, causes easily sliding having some setbacks serious even traffic safety that influence chaufeur.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of carriage of simple in structure, stressed more uniform sliding rail of automobile seat.
The purpose of this utility model can realize by following technical proposal: a kind of carriage of sliding rail of automobile seat, comprise trapped orbit and be located in the trapped orbit and the sliding rail that can in trapped orbit, slide, between trapped orbit and sliding rail, be provided with plurality of balls, it is characterized in that, for bikini contacts, and the distance between per two contact points is all identical between described ball and trapped orbit and the sliding rail.
The trapped orbit of the carriage of this sliding rail of automobile seat is to be connected mutually with the base plate of automobile, and sliding rail is connected mutually with automotive seat.Be provided with ball at trapped orbit and sliding rail, realize moving before and after sliding rail is on trapped orbit by ball, and then realize moving forward and backward of automotive seat.And between ball and trapped orbit and the sliding rail for bikini contacts, and the distance between per two contact points is all identical, the stress point of ball forms an equilateral triangle like this.Make stressed more even between ball and trapped orbit and the sliding rail, the resistance that ball is subjected in sliding process is less, makes the operator can operate moving forward and backward of seat easier, more like a cork.
In the carriage of above-mentioned sliding rail of automobile seat, the contact point between described ball and the sliding rail is one, and the contact point between ball and the trapped orbit is two.Realize contacting between ball and trapped orbit and the sliding rail by such three contact points, and the realization sliding rail slides on trapped orbit by ball.
In the carriage of above-mentioned sliding rail of automobile seat, described ball adopts steel material to make.By the ball that steel material is made, make the hardness of ball, intensity all higher, increase the service life.
In the carriage of above-mentioned sliding rail of automobile seat, described ball is four, described homonymy two balls between be provided with spacer rod.Wherein two balls are positioned at a side of trapped orbit and sliding rail, two other ball is positioned at the opposite side of trapped orbit and sliding rail, between two balls of homonymy a spacer rod is set, ball can not slided into together, it is more light that sliding rail is slided on trapped orbit.
Compared with prior art, three stress points of the ball in the carriage of this sliding rail of automobile seat form an equilateral triangle.Make stressed more even between ball and trapped orbit and the sliding rail, the resistance that ball is subjected in sliding process is less, makes the operator can operate moving forward and backward of seat easier, more like a cork.
Description of drawings
Fig. 1 is the structural representation of the carriage of this sliding rail of automobile seat.
Fig. 2 is the front view of the carriage of this sliding rail of automobile seat.
Among the figure, 1, trapped orbit; 2, sliding rail; 3, ball; 4, spacer rod.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the carriage of this sliding rail of automobile seat comprises trapped orbit 1 and is located in the trapped orbit 1 and the sliding rail 2 that can slide in trapped orbit 1, is provided with plurality of balls 3 between trapped orbit 1 and sliding rail 2,
As shown in Figure 2, for bikini contacts, and the distance between per two contact points is all identical between described ball 3 and trapped orbit 1 and the sliding rail 2.In other words, three of ball 3 stress points form an equilateral triangle.
In the present embodiment, described ball 3 adopts steel material to make.By the ball 3 that steel material is made, make the hardness of ball 3, intensity all higher, increase the service life.Described ball 3 is four, described homonymy two balls 3 between be provided with spacer rod 4.Wherein two balls 3 are positioned at a side of trapped orbit 1 and sliding rail 2, two other ball 3 is positioned at the opposite side of trapped orbit 1 and sliding rail 2, between two balls 3 of homonymy, a spacer rod 4 is set, ball 3 can not slided into together, and it is more light that sliding rail 2 is slided on trapped orbit 1.
The trapped orbit 1 of the carriage of this sliding rail of automobile seat is to be connected mutually with the base plate of automobile, and sliding rail 2 is connected mutually with automotive seat.Be provided with ball 3 at trapped orbit 1 and sliding rail 2, realize moving before and after sliding rail 2 is on trapped orbit 1 by ball 3, and then realize moving forward and backward of automotive seat.And between ball 3 and trapped orbit 1 and the sliding rail 2 for bikini contacts, and the distance between per two contact points is all identical, the stress point of ball 3 forms an equilateral triangle like this.Make stressed more even between ball 3 and trapped orbit 1 and the sliding rail 2, the resistance that ball 3 is subjected in sliding process is less, makes the operator can operate moving forward and backward of seat easier, more like a cork.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used 1, trapped orbit morely; 2, sliding rail; 3, ball; 4, term such as spacer rod, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
