The invention discloses a double-guide multi-ball seat slide rail structure, relates to the technical field of automobile accessories, and solves the problems that an existing seat slide rail slidingmechanism is generally arranged in a sliding chute by adopting a single sliding fulcrum principle, the movement of a sliding rail is unsmooth and blocked due to fact that balls on the supporting surface are provided with a single fulcrum and swing in left-and-right gap in specific use. The double-guide multi-ball seat slide rail structure comprises a seat slide rail, a retaining support and sliding balls, and the retaining support is installed in the seat slide rail in a sliding mode; two mounting grooves are formed in each of the upper side and the lower side of the retaining support; a sliding ball is mounted in each of the four mounting grooves through a bearing; and the four sliding balls are of spherical structures. A set of sliding balls are additionally arranged and distributed at the upper end and the lower end of the retaining support, the front-back sliding four-wheel rolling principle is formed, the problem of left-right shaking in the sliding process is completely eradicated, and the double-guide multi-ball seat slide rail structure is simple in equipment, low in manufacturing cost and stable in performance.

    本发明公开了一种双导向多滚珠座椅滑轨结构,涉及汽车配件技术领域,解决了现有的座椅滑轨滑动机构一般采用单个滑动支点原理布置在滑槽内,其支撑面的滚珠由于时单个支点,在具体使用时会因为左右间隙的摇摆,使滑轨的运动不畅受阻的问题。一种双导向多滚珠座椅滑轨结构,包括座椅滑轨,保持支架和滑动滚珠,所述座椅滑轨内滑动安装有一处保持支架;所述保持支架的上下两侧均开设有两处安装槽;四处所述安装槽内均通过轴承安装有一处滑动滚珠;四处所述滑动滚珠为球形状结构。本发明增加一组滑动滚珠,分布在保持支架的上下两端位置,形成前后滑动四轮滚动的原理,杜绝了滑动时左右晃动的问题,本发明装备简单,造价较低且性能稳定。
