Description

A kind of seat sliding device for vehicles of high strength locking

[technical field]

The utility model relates to a kind of seat sliding device for vehicles, particularly a kind of seat sliding device for vehicles of high strength locking.

[background technology]

The seat that automobile is used is now pursued variation, not only, for front chair, be all provided with seat sliding apparatus for back seat, carriage setting simultaneously, the upper slide rail of being combined with seat that is assembled with sliding on the glidepath that is fixed on car bottom plate freely, and be provided with lockout mechanism.

List slide rail from slide rail, upper slide rail product section great majority are in the market regular integral types, this style is subject to the restriction of material, causes intensity substantially a scope, there is no larger leap.With on the single locking arm that coordinates of slide rail, lock arm initial stage of design with the space different designs of upper slide rail differ, and the anglec of rotation, lock pawl size, the importance that in embodiments, slide rail designs.Its lockout mechanism of existing seat sliding apparatus is easily out of shape dropout, causes locking undercapacity; Meanwhile, the required angle of the disengaging of lockout mechanism is larger, affects whole topological design.

[summary of the invention]

The technical problems to be solved in the utility model, is to provide a kind of seat sliding device for vehicles of high strength locking, can effectively promote the locking intensity of railroad.

The utility model is achieved in that

A seat sliding device for vehicles for high strength locking, glidepath and lockable mechanism that described carriage comprises slide rail, matches with its shape, described upper slide rail and glidepath are by the mutual locking of lockable mechanism;

Described upper slide rail comprises one " ㄇ " type backbone and two U-shaped grooves, described two U-shaped grooves are separately positioned on the both sides of " ㄇ " type backbone, and the both sides of described " ㄇ " type backbone join with one side of corresponding U-shaped groove respectively, described ㄇ " type backbone and two U-shaped grooves one-body molded, the opening of each U-shaped groove is all less than the opening of " ㄇ " type backbone;

Described glidepath is one " Qian " type, and both ends extend to respectively in the U-shaped groove that stretches into correspondence;

Described lockable mechanism comprises a fixed support, a lock arm and is arranged on the lock pawl of lock arm front end, described fixed support is fixed on slide rail, described lock arm is articulated by a pivot pin and fixed support, on described pivot pin, be also arranged with a torsion spring, described lock pawl is engaged on the U-shaped groove of slide rail one side and stretches in the lock hole of glidepath end of this U-shaped groove; The opening that is engaged with the U-shaped groove of lock pawl is 3.6mm.

The utility model has the advantage of:

The described lock pawl of lock arm is engaged on the U-shaped groove of slide rail one side and stretches in the lock hole of glidepath end of this U-shaped groove, upper slide rail and glidepath is locked; When disengaging, apply certain effect power at the free end of lock arm, lock arm is done rotation start with pivot pin, and first lock pawl departs from the lock hole in sliding rail U-shaped groove outside, then the lock hole that departs from glidepath end, finally separates with inside U-shaped groove.This opening that is engaged with the U-shaped groove of lock pawl is 3.6mm, also relative minimizing the distance of upper slide rail and upper slide rail dwindle, when slide rail is threaded off, due to Distance Shortened, lock arm opening angle also dwindles, and makes the space of carriage inside larger, improves the degree of freedom of layout; In addition, the length of lock pawl is corresponding shortening also, has saved cost, has alleviated weight, not yielding dropout, and actv. promotes the locking intensity of railroad.

[accompanying drawing explanation]

The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the schematic cross-section of Fig. 1 along A-A direction.

[specific embodiment]

Refer to shown in Fig. 1 and Fig. 2, embodiment of the present utility model is described in detail.

As depicted in figs. 1 and 2, the seat sliding device for vehicles of the related a kind of high strength locking of the utility model, glidepath 2 and lockable mechanism 3 that described carriage comprises slide rail 1, matches with its shape, described upper slide rail 1 and glidepath 2 are by the mutual locking of lockable mechanism 3;

Described upper slide rail 1 comprises one " ㄇ " type backbone 11 and two U-shaped grooves 12, described two U-shaped grooves 12 are separately positioned on the both sides of " ㄇ " type backbone 11, and the both sides of described " ㄇ " type backbone 11 join with one side of corresponding U-shaped groove 12 respectively, described ㄇ " type backbone 11 and two U-shaped grooves 12 one-body molded, the opening of each U-shaped groove 12 is all less than the opening of " ㄇ " type backbone 11;

Described glidepath 2 is one " Qian " type, and both ends 21 extend to respectively in the U-shaped groove 12 that stretches into correspondence;

Described lockable mechanism 3 comprises a fixed support 31, a lock arm 32 and is arranged on the lock pawl 33 of lock arm 32 front ends, described fixed support 31 is fixed on slide rail 1, described lock arm 32 is articulated with fixed support 31 by a pivot pin 34, on described pivot pin 31, be also arranged with a torsion spring 35, described lock pawl 33 is engaged on the U-shaped groove 12 of slide rail 1 one sides and stretches in the lock hole (not shown) of glidepath 2 ends 21 of this U-shaped groove 12; The opening that is engaged with the U-shaped groove 12 of lock pawl 33 is that the spacing of 12 liang of corresponding inwalls of U-shaped groove is 3.6mm.

The lock pawl 33 of lock arm 32 of the present utility model is engaged on the U-shaped groove 12 of slide rail 1 one sides and stretches in the lock hole of glidepath 2 ends 21 of this U-shaped groove 12, upper slide rail 1 and glidepath 2 is locked; When disengaging, apply certain effect power at the free end of lock arm 32, lock arm 32 is done rotation start with pivot pin 34, and first lock pawl 33 departs from the lock hole in U-shaped groove 12 outsides of slide rail 1, depart from again the lock hole of glidepath 2 ends 21, finally separate with U-shaped groove 12 inner sides.This opening that is engaged with the U-shaped groove 12 of lock pawl 33 is 3.6mm, also relative minimizing the distance of upper cunning 1 rail and upper slide rail 2 dwindle, when railroad is threaded off, due to Distance Shortened, lock arm 32 opening angles also dwindle, make the space of carriage inside larger, improve the degree of freedom of layout; In addition, the length of lock pawl is corresponding shortening also, has saved cost, has alleviated weight, not yielding dropout, and actv. promotes the locking intensity of railroad.

Although more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
