[0023] Reference Figures 1 to 5As shown, a transmission box hidden curtain track assembly of this embodiment includes a track body 1 and a cover plate 2. The cover plate 2 is provided on one end of the track body 1. The other end of the track body 1 is used to connect to the main transmission box. The track body 1 is connected to the motor through the main transmission box, so that the curtain can be opened and closed by the motor.

[0024] An accommodating cavity 11 is formed on the track body 1 at one end of the cover plate 2. A transmission member 3 that is driven by a belt is connected to the accommodating cavity 11. The accommodating cavity 11 provides an accommodating space for the transmission member 3. The main transmission box includes at least one gear that engages with the belt. The motor drives the gear to rotate, and the transmission member 3 plays a transmission role, so that the belt can drive the curtain to move. The belt and the curtain are connected by a pulley.

[0025] Among them, the transmission member 3 is placed in the accommodating cavity 11, which eliminates the cavity for accommodating the transmission member 3 set on the auxiliary transmission box, thereby reducing the space occupied by the auxiliary transmission box as a whole. The auxiliary transmission box can be set as a cover plate 2, which can cover one end of the track body 1, and the design length of the track body 1 can be extended.

[0026] Reference Figure 2 and Figure 4 As shown, the transmission member 3 is a bearing, a transmission wheel or a transmission gear;

[0027] In one embodiment, the transmission member 3 is a bearing, and the outer ring of the bearing is tensioned with the belt. When the belt rotates through the main transmission box, the outer ring of the bearing rotates.

[0028] In the second embodiment, the transmission member 3 is a transmission wheel, which is rotatably connected to the accommodating cavity 11 and rotates with the rotation of the belt;

[0029] In the third embodiment, the transmission member 3 is a transmission gear, which is engaged with the belt to realize transmission of the belt.

[0030] Preferably, the transmission member 3 is a bearing.

[0031] Reference Figure 3 As shown, the track body 1 includes two oppositely arranged through grooves 12, and two oppositely arranged limit strips 13 are formed in the through grooves 12, wherein the space between the through grooves 12 and the limit strips 13 is used to accommodate the belt, and the belt extends from the space on one side to the space on the other side to form a closed loop. The limit strip 13 is located at one end of the cover plate 2 and is formed with a notch 131. The setting of the notch 131 can avoid interference between the limit strip 13 and the belt.

[0032] In one embodiment, the gap 131 may be a section just for the belt to pass through;
