Description

Seat slide rail anticreep assembly

Technical Field

The utility model relates to a slide rail anti-falling technology, in particular to a seat slide rail anti-falling assembly.

Background

The automobile seat slide rail is one of important parts in an automobile, and the safety of the sliding is always the focus of product development. The automobile seat slide rail comprises an upper slide rail and a lower slide rail, wherein the two sides of the upper slide rail and the lower slide rail are both bent and are mutually hooked through bending parts to prevent falling off, the upper slide rail can slide relative to the lower slide rail to realize the front and back adjustment of the seat, and a passenger can adjust the seat to the most comfortable position according to requirements.

When the inner and lower slide rails of the vehicle seat are used in the detection or use process, as shown in fig. 1 and fig. 2, an inner cavity is formed by enclosing the upper slide rail 3 and the lower slide rail 4, when the upper slide rail 3 slides to the rear final position, the bending parts at the two sides of the upper slide rail and the lower slide rail are thin, the strength is weak, effective anti-falling can not be realized after the upper slide rail and the lower slide rail are hooked, the upper and lower separation conditions from the lower slide rail 4 are easy to occur, and great potential safety hazards exist. In order to prevent the hidden danger, a square plastic block is usually plugged into a closed space formed by the upper slide rail 3 and the lower slide rail 4, but the plastic block is poor in strength, so that the plastic block is easy to break in collision or high temperature, and the problem that the inner slide rail and the lower slide rail are separated from each other up and down cannot be fundamentally solved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a seat slide rail anti-falling assembly for ensuring the final position of an inner slide rail and a lower slide rail to be stable, and solves the problem that the upper slide rail is separated from the lower slide rail when sliding to the rear final position.

Therefore, the technical scheme adopted by the utility model is as follows: the utility model provides a seat slide rail anticreep assembly, includes slide rail, lower slide rail, and the left and right sides is all bent and is colluded each other through the portion of bending and hang together, still including the last anticreep piece that is located slide rail rear end and the lower anticreep piece that is located slide rail rear end down, it has the breach to go up whole "U" type and the bottom of anticreep piece, and both vertical ends are fixed on the lateral wall of last slide rail about, and lower anticreep piece is "T" type and lower extreme with the help of the through-hole riveting or the welding installation in slide rail area down, and anticreep piece horizontal end width is greater than anticreep piece breach width down, is less than the distance between the two vertical ends of anticreep piece, when going up the slide rail and removing to final position backward, and anticreep piece vertical end card goes up the breach department of anticreep piece down.

Preferably, the gap fit clearance between the vertical end of the lower anti-falling part and the upper anti-falling part is 0.8-1.2 mm, so that the phenomenon that the gap between the vertical end of the lower anti-falling part and the upper anti-falling part is too large to shake or the gap between the vertical end of the lower anti-falling part and the upper anti-falling part is too small to collide and wear is avoided, the fit clearance between the horizontal end of the upper anti-falling part and the horizontal end of the lower anti-falling part is 1.6-2.0 mm, the phenomenon that the upper anti-falling part and the lower anti-falling part rub and extrude with each other to cause damage or deformation of parts is avoided, the sliding of an upper sliding rail is blocked, and the use effect of the seat is further influenced.

Further preferably, the left vertical end and the right vertical end of the upper anti-falling part are fixed on the upper sliding rail in a welding mode, and the structure is stable and firm.

Further preferably, go up anticreep spare and anticreep spare down and all adopt stainless steel, go up anticreep spare thickness and be greater than last slide rail, lower slide rail, thickness is 2.8 ~ 3.2mm, and intensity is high non-deformable, and overall design is reasonable.

Further preferably, the corners and the bending parts of the upper anti-falling part are provided with fillets, so that damage to components caused by collision during installation or use is avoided.

The utility model has the beneficial effects that:

(1) go up whole "U" type and the bottom of anticreep piece and have the breach, control both ends vertical end and fix on the lateral wall of last slide rail, anticreep piece is "T" type and lower extreme with the help of slide rail down from the through-hole riveting or the welded mounting in area down, the slide rail rivets from taking the through-hole under the ingenious combination, the structure is firm, go up the slide rail when backward slip to final position, the vertical end of anticreep piece just in time blocks into the breach department of anticreep piece down, reasonable in design, convenient operation is swift.

(2) The horizontal end width of the lower anti-falling part is greater than the width of the gap of the upper anti-falling part and smaller than the distance between the two vertical ends of the upper anti-falling part, so that when the upper slide rail is separated upwards, the horizontal end of the lower anti-falling part cannot move out from the gap of the upper anti-falling part.

(3) When the upper slide rail moves backwards to the final position, the vertical end of the lower anti-falling part is clamped into the notch of the upper anti-falling part, so that safety accidents caused by the separation of the upper slide rail are effectively avoided, and the life health of passengers is endangered.

In conclusion, the anti-falling assembly for the seat slide rail has the characteristics of good anti-falling effect and simplicity in operation, and is high in practicability.
