The hidden assembly 2 comprises a mounting tube 7, and a circular groove is provided on the top outer wall of the mounting tube 7, and a column head 8 is slidably installed on the inner wall of the circular groove. The cross-section of the column head 8 is a T-shaped structure, and the specifications of the column head 8 match the specifications of the groove 4. Through the cooperation between the guide rail assembly 1 and the hidden assembly 2, the movement of the auxiliary electric telescopic door is facilitated, and the groove 4 on the guide rail 3 facilitates the auxiliary column head 8 to slide therein, and the column head 8 of the T-shaped structure will not be detached when entering the groove 4.

[0031] For details, please refer to Figure 4Two slide bars 9 are fixedly connected to the inner wall of the circular groove, and the outer walls of the two slide bars 9 are slidably connected to the same slide seat 10. The setting of the slide bars 9 facilitates and directly limits the sliding track of the slide seat 10.

[0032] For details, please refer to Figure 4 The sliding seat 10 is fixedly connected to the column head 8, and the inner walls on both sides of the circular groove are rotatably connected to the same wire-receiving roller 11, and the column head 8 is directly driven to move by the sliding of the sliding seat 10.

[0033] For details, please refer to Figure 4 Two steel ropes 13 are wound around the outer wall of the take-up roller 11, and one end of the two steel ropes 13 is fixedly connected to the sliding seat 10. The arrangement of the take-up roller 11 facilitates the winding of the steel ropes 13.

[0034] For details, please refer to Figure 4 Both ends of the transmission shaft of the take-up roller 11 are sleeved with a volute spring 12, and two mounting grooves 14 are provided on the outer wall of the bottom of the column head 8. The inner wall of the mounting groove 14 is provided with a sliding component.
