Detailed Description

In order to facilitate an understanding of the utility model, the device of the utility model will be described more fully below with reference to the accompanying drawings. Examples of the apparatus are given in the accompanying drawings. However, the apparatus may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Examples

As shown in fig. 1-5, this embodiment provides a sliding rail of an electric seat, including a lower rail 1 and an upper sliding core 2, the lower rail 1 is connected with the upper sliding core 2 through ball members on two sides, the ball members include two ball limiting shells 10 and a connecting rail 12, two ball limiting shells 10 are integrally formed with two sides of the connecting rail 12, a spherical groove for placing balls 11 is formed inside the ball limiting shells 10, through an integrally formed design, the conventional separated limiting shells can realize synchronous movement, the stability of the movement of the seat is ensured, and the situation that single separation affects the movement can not occur. The lower track 1 is concave, the upper slide core 2 is a few words, the upper slide core 2 is clamped at the groove of the lower track 1, the assembly is more convenient and faster in a clamping mode, the arc grooves 8 matched with the balls 11 are formed at the upper end and the lower end of the two sides of the upper slide core 2, the outer surfaces of the balls 11 are respectively contacted with the arc grooves 8 and the corners of the grooves, the horizontal positions of the corners of the grooves and the arc grooves 8 are limited by the balls 11, the good fixing effect can be achieved under the condition that the sliding is not affected, the torsion resistance is good, and the derailment phenomenon is prevented. The spherical groove comprises two groove holes at the top and three groove holes at the bottom, and the height value of the connecting rail 12 is smaller than that of the ball limiting shell 10, so that the connecting rail cannot be connected with the lower rail 1 during sliding, friction force is reduced, and sliding is smoother.
