The invention provides a high-strength front electric sliding rail. The high-strength front electric sliding rail comprises an upper rail body, a lower rail body, a retainer assembly and a transmission mechanism assembly. The upper rail can be matched with the lower rail in a sliding manner along the lower rail; the retainer assembly is arranged in the retainer accommodating space; the transmission mechanism assembly is arranged in the transmission mechanism accommodating space and is connected with the upper rail and the lower rail; the transmission mechanism assembly comprises a gearbox assembly, a lead screw, two check ring assemblies and a nut support assembly. One end of the screw rod is in transmission connection with the gearbox assembly; the two ends of the lead screw are each connected with a check ring assembly, and the gear box assembly and the check ring assemblies are fixed to the upper rail. The nut support assembly is arranged outside the lead screw in a sleeving mode through the inner threaded hole and fixed to the lower rail. According to the high-strength front electric sliding rail, the front-back symmetrical check block design is adopted, the integrated check ring is adopted, and the nut support is designed in a sectional mode; therefore, the sliding rail can bear higher strength and meet the requirement of 40KN.

    本发明提供一种高强度前置电动滑轨,包括上轨、下轨、保持架总成和传动机构总成;上轨可沿下轨滑动地与下轨配合设置;保持架总成设置于保持架容纳空间内;传动机构总成设置于传动机构容纳空间内并连接上轨和下轨;传动机构总成包括齿轮箱总成、丝杆、两挡圈组件和螺母支架组件;丝杆一端与齿轮箱总成传动连接;丝杆的两端分别连接一挡圈组件,齿轮箱总成和挡圈组件与上轨固定;螺母支架组件通过内螺纹孔套设于丝杆外,螺母支架组件与下轨固定。本发明的一种高强度前置电动滑轨,采用前后对称挡块设计,采用一体式挡圈,且螺母支架采用分段式设计;使滑轨可承受更高的强度,满足40KN要求。
