Electric opening device for vehicle door

SHU XIAOJUN / WANG SHAOYA / KIM SUNG-HO

The invention provides a vehicle door electric opening device which comprises an electric supporting rod, a sliding mechanism, a connecting rod mechanism and a control unit, the sliding mechanism comprises a sliding rail and a sliding block limited in the sliding rail and capable of sliding along the sliding rail, the telescopic end of the electric supporting rod is fixedly connected with the sliding block, one end of the connecting rod mechanism is hinged to a vehicle door, and the other end of the connecting rod mechanism is hinged to the sliding block. The two ends of the connecting rod mechanism can rotate around the corresponding hinge points respectively, the electric supporting rod is fixed to the lower portion of the outer side of the threshold, the control unit controls the electric supporting rod to stretch out and draw back, and the electric supporting rod stretches out and draws back to drive the sliding block to slide along the sliding rail and the connecting rod mechanism to rotate around the hinge points to open or close the automobile door. According to the electric opening device for the vehicle door, the electric supporting rod is adopted, an electric limiting stopper is omitted, the product cost is reduced, the overall structure is simple, the operation stability is good, the failure rate is low, arrangement of other vehicle door components is facilitated, the modeling freedom degree is better, and the collision resistance of a vehicle body is higher.

本发明提供一种车门电动开启装置，包括电动撑杆、滑动机构、连杆机构、以及控制单元，滑动机构包括滑轨和限位于滑轨中并可沿着滑轨滑动的滑块，电动撑杆的伸缩端与滑块固定连接，连杆机构一端与车门铰接，连杆机构另一端与滑块铰接，连杆机构两端可分别绕相应铰接点转动，电动撑杆固定于门槛外侧下部，控制单元控制电动撑杆的伸缩，电动撑杆伸缩运动带动滑块沿滑轨滑动以及连杆机构绕铰接点转动而将车门开启或关闭。上述车门电动开启装置，采用电动撑杆而取消了电动限位器，降低了产品成本，总体结构简单，运行稳定性好，故障率低，便于其他车门部件的布置，造型自由度更好，车身抗碰撞性能更强。
