Utility model content

The purpose of this utility model is to provide a kind of ISOFIX electrical retractor of automotive seat, can realize the automatic telescopic of ISOFIX, simplify operation when using child safety seat, and structure is simple.

The purpose of this utility model is achieved in that

An ISOFIX electrical retractor for automotive seat, comprising: a drive motor, is fixed on seat cushion framework; A pair guide groove, be located at abreast described seat cushion framework two inside; One sliding track mechanism, is located between described guide groove, and slidably along described guide groove to seat cushion interior or outside movable, the outer end of described sliding track mechanism is provided with ISOFIX fixed interface; One screw body, comprises a screw rodb base and a screw mandrel, and described screw rodb base is fixed on described sliding track mechanism, and one end of described screw mandrel is rotatably fixed in described screw rodb base, and the other end is connected with described drive motor, and described screw mandrel is parallel with described guide groove; Described drive motor drives described sliding track mechanism to move forward and backward along described guide groove by described screw body.

The ISOFIX electrical retractor of a kind of automotive seat of the utility model drives screw body by drive motor, screw body converts rotary motion to straight-line motion and passes to sliding track mechanism, straight-line motion is passed to ISOFIX fixed interface by sliding track mechanism, and the electric expansion finally realizing ISOFIX controls.

Wherein, described sliding track mechanism comprises two parallel guide rods, and wherein a guide rod is located in a guide groove, and another root guide rod is located in another root guide groove, and described two guide rods are along synchronizing moving before and after described guide groove.

Further, in the outer end of described guide rod, be provided with a polished rod between two guide rods, described ISOFIX fixed interface is fixed on described polished rod; Be provided with a fixed link between described two guide rods, described screw rodb base is fixed on described fixed link.Wherein, described fixed link is U-shaped steel; Described fixed link is welded between described two guide rods.

When described drive motor starts, described screw mandrel rotates under the drive of drive motor, and then described screw mandrel drives described guide rod to move forward and backward along guide groove in guide groove, thus drives ISOFIX fixed interface to move forward and backward.

Accompanying drawing explanation

By following embodiment of the present utility model and description taken together with the accompanying drawings, other advantage of the present utility model and feature are shown, this embodiment provides by way of example, but is not limited to this, wherein:

Fig. 1 is the structural representation of a preferred embodiment of the ISOFIX electrical retractor of a kind of automotive seat of the utility model.

Fig. 2 is the structural representation of sliding track mechanism embodiment illustrated in fig. 1.

Detailed description of the invention

The ISOFIX electrical retractor of automotive seat as shown in the figure, be provided with a pair guide groove 2, be provided with a motor bearing platform 3 between two guide grooves 2 in seat cushion framework 1, drive motor 4 is fixed on motor bearing platform 3 two inside parallel of seat cushion framework 1.One sliding track mechanism 5 is located between guide groove 2, can move forward and backward in the drive lower slider of screw body 6 along guide groove 2 to seat cushion interior or outside.Sliding track mechanism 5 comprises two parallel guide rods 51, is located in two guide grooves 2 respectively, in the outer end of guide rod 51, is provided with polished rod 52, an ISOFIX fixed interface 7 and is fixed on polished rod 52, be also provided with a fixed link 53 between two guide rods 51 between two guide rods 51.Screw body 6 comprises screw rodb base 61 and a screw mandrel 62, and screw rodb base 61 is fixed on fixed link 53, and screw mandrel 62 is parallel with guide groove 2, and one end is rotatably fixed in screw rodb base 61, and the other end is connected with drive motor 4.Drive motor 4 drives sliding track mechanism 5 to move forward and backward along guide groove 2 by screw body 6, thus drives the ISOFIX fixed interface 7 being fixed on sliding track mechanism 5 outer end to move forward and backward.

In the present embodiment, fixed link 53 is U-shaped steel.

Although the utility model is illustrated hereinbefore according to preferred embodiment, but this does not represent that scope of the present utility model is confined to above-mentioned structure, as long as the equivalent substitution structure that those skilled in the art can develop easily after reading above-mentioned explanation, the equalization done under the spirit not departing from the utility model and scope changes and modifies, and all should be covered by within the utility model the scope of the claims.
