Description
Technical field
The utility model relates to auto parts and components field, more specifically, relates to a kind of track-type facilities for seat.
Background technology
Track-type facilities is used for front and back adjustment seat so that occupant location, and general track-type facilities is by get on the right track and lower railway and the one group of spheroid be arranged between the two form, and the effect of spheroid is mainly in order to be used for reducing friction resistance.In known track-type facilities, to get on the right track and application force between lower railway causes the multiple points contacted with spheroid in orbit create larger power, and this power is being got on the right track by the weight of seat people on the seat and produced between lower railway, this masterpiece is used on spheroid, spheroid acts on guide rail and guide rail can be caused to cave in, this depression can damage the roll capability of spheroid, thus makes track-type facilities ineffective.
Summary of the invention
The utility model is for overcoming at least one defect described in above-mentioned prior art, two groups of rolling bodys are used to carry, two groups of rolling bodys are small one and large one, two groups of rolling bodys can strengthen carrying effect, and according to the structure of track, the center of circle of two groups of rolling bodys is coaxially arranged, thus strengthens load-carrying capacity.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of track-type facilities for seat, comprise outside track, the inner orbit corresponding with described outside track, described outside track and described inner orbit are relative to each other installed movably via the first rolling body and the second rolling body, described outside track comprises two group of first kink, described inner orbit comprises two group of second kink, described second rolling body is provided with between described first kink and described second kink, the first rolling body is provided with between described second kink and the inwall of described outside track, the diameter of described first rolling body is greater than the diameter of described second rolling body.
Further, the center of circle of the center of circle of described first rolling body and described second rolling body on the same axis.
Further, described first rolling body is ball.
Further, described second rolling body is ball.
Further, described outside track and described inner orbit are the form of open contours.
Compared with prior art, the beneficial effects of the utility model are:
A kind of track-type facilities for vehicle of the present utility model has disperseed the stressed of guide rail, improves the load-carrying capacity of track-type facilities, effectively can improve the work life of guide rail, this guide rail structure advantages of simple in addition simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of track-type facilities for seat of the utility model.
In figure: 1, outside track; 2, inner orbit; 3, the first rolling body; 4, the second rolling body; 5, the first kink; 6, the second kink.
Detailed description of the invention
For the technical characterstic of this programme can be described, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the utility model is a kind of track-type facilities for seat, this rail set possesses outside track 1, this outside track 1 can match with inner orbit 2 corresponding thereto, two groups of rolling bodys are provided with between outside track 1 and inner orbit 2, being respectively the first rolling body 3 and the second rolling body 4, two groups of rolling bodys for supporting human body application force on the seat, seat relative movement also can be made simultaneously to adjust location.
Wherein, outside track 1 comprises one group of first kink 5, and inner orbit 2 comprises one group of second kink 6, first rolling body 3 and is arranged between the second kink 6 and the inwall of described outside track 1, and the second rolling body 4 is arranged between the first kink 5 and the second kink 6.The diameter of the first rolling body 3 is larger than the diameter of the second rolling body 4, both dispersible the gravity of seat, the diameter of the first rolling body 3 is greatly structure according to track-type facilities than the diameter of the second rolling body 4 and designs, and both centers of circle on the same axis, the bearing value of track-type facilities can be strengthened.In addition, the first rolling body 3 and the second rolling body 4 all can select ball.In addition, outside track 1 and inner orbit 2 are open contours pattern, and such design can make vehicle rail device assemble more easily.
In addition, in order to block the first rolling body 3 and the second rolling body 4, the second kink 6 making inner orbit 2 is needed to design different from the design of the first kink of outside track 1, and the middle part of the second kink of inner orbit 2 is utilized arc transition, this arc transition can prevent rolling body unsceptered, thus make rolling body stationary positioned, make its supporting guide device better.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
