The invention discloses a fixing device of a truck battery replacement battery pack and an operation method thereof. The fixing device is characterized by comprising a battery pack and a frame base, a locking mechanism is mounted at the bottom of the battery pack; a middle connecting frame for fixing a battery pack is arranged on the frame base; a plurality of groups of Y-axis guide brackets are arranged on the side edge of the middle connecting frame, and the end parts of each group of Y-axis guide brackets are inclined planes which are inclined oppositely; a Y-axial locking pin hole is formed in the Y-axial guide bracket; the locking mechanism comprises a power mechanism, and the power mechanism is in transmission connection with at least one locking assembly through an X-axis middle transmission shaft. The locking assembly comprises a quadrilateral connecting rod and a lead screw penetrating through the vertical angle, and the lead screw and the middle transmission shaft are in coaxial transmission. And the other group of opposite corners of the quadrilateral connecting rod are provided with locking pins which stretch out and draw back along the Y-axis direction. The self-locking function of the screw rod is ensured by reasonably arranging the lead angle of the trapezoidal screw rod, and the power of the high-speed shaft of the speed reducer is led to the side surface of the battery pack through the intermediate shaft.

    本发明公开了一种卡车换电电池包的固定装置及其运行方法,其特征在于:包括电池包和车架底座;所述的电池包的底部安装有锁紧机构;所述的车架底座设置有固定电池包的中间连接架;所述的中间连接架侧边上设置有若干组Y轴向导向支架,每组Y轴向导向支架的端部为相向倾斜的斜面;Y轴向导向支架上设置有Y轴向的锁紧销孔;所述的锁紧机构包括动力机构,动力机构通过一X轴向的中间传动轴与至少一组锁紧组件传动连接;所述的锁紧组件包括四边形连杆和穿过对顶角的丝杆,丝杆与中间传动轴同轴传动;四边形连杆的另一组对角上设置有沿Y轴方向上伸缩的锁紧销。通过合理设置梯形丝杆的螺纹升角保证丝杆有自锁功能,另外通过中间轴把减速机高速轴动力引到电池包侧面。
