Abstract
The invention relates to a sliding rail for an automobile seat. The sliding rail comprises a sliding shell, a sliding core and steel balls; the lower end of the inner vertical folded wall of the sliding core is connected with the lower end of the outer vertical folded wall through an arc folded wall; the upper and lower ends of the sliding shell are provided with an upper groove-shaped folded wall and a lower groove-shaped folded wall respectively; the arc folded wall of the sliding core and the lower groove-shaped folded wall at the lower end of the sliding shell form a lower steel ball passage; the steel balls are arranged in the lower steel ball passage; the sliding rail is characterized in that: the upper end of the outer vertical folded wall of the sliding core is provided with an inner bent wall, the inner bent wall and the upper groove-shaped folded wall of the upper end of the sliding shell form an upper steel ball passage, and the steel balls are arranged in the upper steel ball passage. The sliding rail has the advantages that: the sliding core and the sliding shell can be combined well to ensure smooth movement when traction and impact force is supplied to the sliding rail by swinging and bumping generated during running of an automobile.
Description
Technical field
The present invention relates to a kind of slide rail, relate in particular to a kind of slide rail that is used for seat.
Background technology
The slide rail that is used for seat at present comprises slip case, slide core and steel ball, the interior vertical folding partition lower end of slide core with outside the vertical folding partition lower end be connected by arc folding wall; Channel shaped folding wall and hyposulculus flute profile folding wall on the slip case upper and lower end has respectively; The hyposulculus flute profile folding wall of the arc folding wall of slide core and slip case lower end forms a steel ball passage; Be provided with steel ball in the steel ball passage; Tractive force and impulsive force that this slide rail that is used for seat waves when running car, jolts and give slide rail, when particularly the seatbelt attachment point places the slide rail rear side, slide rail is worked under half friction of rolling and half cliding friction state, causes the phenomenon that slide rail adjustment clamping stagnation has some setbacks easily.
Summary of the invention
At above-mentioned shortcoming, the object of the present invention is to provide a kind of slide rail that is used for seat, it can wave when running car, when jolting the tractive force that gives slide rail and impulsive force, make slide core and slip case in conjunction with intact, and it is smooth and easy to move.
Technology contents of the present invention is, a kind of slide rail that is used for seat comprises slip case, slide core and steel ball, and the interior vertical folding partition lower end of slide core is connected by arc folding wall with outer vertical folding partition lower end; Channel shaped folding wall and hyposulculus flute profile folding wall on the upper and lower end of slip case has respectively; The hyposulculus flute profile folding wall of the arc folding wall of slide core and slip case lower end forms steel ball passage; Be provided with steel ball in the following steel ball passage; It is characterized in that the upper end in the outer vertical folding partition of slide core is the inner bending wall, steel ball passage in the last channel shaped folding wall formation one of inner bending wall and slip case upper end is provided with steel ball in last steel ball passage.
Be shaped by cold stamping by high tensile steel plate at above-mentioned slide rail slide core and the slip case that is used for seat; The circular arc and the steel ball radius of channel shaped folding wall and hyposulculus flute profile folding wall match on the upper and lower end of slip case; The arc folding wall on slide core and the circular arc of inner bending wall also match with the steel ball radius.
The advantage that the present invention is compared with prior art had is:
1, steel ball and the folding wall inside face that forms the steel ball passage are realized sliding to contact among the present invention, and its sliding resistance reduces relatively, and it is more smooth and easy to slide.
2, slide core of the present invention is resisted the separating force height with slip case, slide core can not be separated when the automobile experience knocks into the back or clashes into slip case.

Fig. 2 is the front view of Fig. 1.
Fig. 3 is a kind of rail structure scheme drawing of prior art.
Specific embodiment
As depicted in figs. 1 and 2, a kind of slide rail that is used for seat comprises slip case 1, slide core 2 and steel ball 3, and interior vertical folding partition 2.1 lower ends of slide core 2 are connected by arc folding wall 2.3 with outer vertical folding partition 2.2 lower ends; Channel shaped folding wall 1.1 and hyposulculus flute profile folding wall 1.2 on the upper and lower end of slip case 1 has respectively; The hyposulculus flute profile folding wall 1.2 of the arc folding wall 2.3 of slide core 2 and slip case 1 lower end forms steel ball passage 4; Be provided with steel ball 3 in the following steel ball passage 4; It is characterized in that the upper end in the outer vertical folding partition 2.2 of slide core 2 is an inner bending wall 2.4, steel ball passage 5 in last channel shaped folding wall 1.1 formation one of inner bending wall 2.4 and slip case 1 upper end is provided with steel ball in last steel ball passage 5.
Constitute a straight line kinematic pair by the steel ball in upper and lower two pairs of steel ball passages 4,5 and the passage 3 between slide core 2 among the present invention and the slip case 1; Last steel ball passage 5 has made full use of the elastic deformation effect of high-strength plate, slide rail unlikely generation when being subjected to normal tractive force is slided block; When tractive force excessive, arc folding wall 2.3 places that make slide core 2 are subjected to the normal force effect and when being out of shape to the inside, the gap of the last cross break wall 1.3 of inner bending wall 2.4 tops and slip case 1 is tending towards null value, slide core 2 produces directly effect with slip case 1 at the contact surface place, thereby avoids slide core 2 and slip case 1 generation to separate inefficacy and cause the human injury.
As shown in Figure 3, a kind of slide rail of seat of prior art comprises slip case 6, slide core 7 and steel ball 8, interior vertical folding partition 7.1 lower ends of slide core 7 with outside vertical folding partition 7.2 lower ends be connected by arc folding wall 7.3; Channel shaped folding wall 6.1 and hyposulculus flute profile folding wall 6.2 on slip case 6 upper and lower ends have respectively; The hyposulculus flute profile folding wall 6.2 of the arc folding wall 7.3 of slide core 7 and slip case 6 lower ends forms a steel ball passage 9; Be provided with steel ball 8 in the steel ball passage 9.
