The curtain bottom rail 94 with the gravity center adjusting function has the beneficial effects that: compared with the prior art, the curtain lower rail 94 is provided with the adjusting module 942, when the curtain lower rail 94 is askew, the controller can control the first electromagnetic component 21 and the second electromagnetic component 22 to work so as to attract the magnetic medium to move in the length direction of the lower rail body 941, so that the gravity center of the curtain lower rail 94 is adjusted to enable the curtain lower rail 94 to recover to a horizontal state, and the using convenience of the curtain can be improved; the flow cavity 11 is located at a middle position of the lower rail body 941 along the first direction X, in an initial state, the magnetic medium is uniformly distributed in the flow cavity 11 so as to balance the gravity center of the adjusting module 942, and the gravity center of the adjusting module 942 is as close to the center of the lower rail body 941 as possible, so that the stability of the curtain lower rail 94 in the initial state can be improved.
The adjustment module 942 may be modular in design and may be adapted for use with different shade devices and may be installed on existing window covering lower rails 94.
The base 10 has a flow chamber 11, and the flow chamber 11 may be in a strip shape extending along a first direction X, for example, substantially in a rectangular parallelepiped shape, a length direction of the rectangular parallelepiped being along the first direction X, a width direction of the rectangular parallelepiped being along a second direction Y, and a height direction of the rectangular parallelepiped being along a third direction Z. The first direction X, the second direction Y, and the third direction Z may constitute a space rectangular coordinate system.
The magnetic medium is free to move or flow within the flow chamber 11. The magnetic medium may be in particulate, powdered or fluid form. For example, the magnetic medium may be iron beads, iron powder, or a magnetic liquid. The magnetic medium is a fluid, which may be, for example, a liquid, a solid-liquid mixture, or a freely deformable gel.
The first electromagnetic assembly 21 and the second electromagnetic assembly 22 include a plurality of (e.g., two) electromagnetic coils 211 arranged in the width direction of the flow chamber 11.

The vibration motor 31 may be employed to drive the base 10 to vibrate.
The vibration motor 31 is connected to the base 10 and is used to vibrate the base 10. Preferably, the vibration motor 31 is provided below the flow chamber 11 at a middle position of the flow chamber 11 in the first direction X. This can make the vibration of the base 10 more uniform.
Referring to fig. 4, the base 10 is further provided with a circuit cavity 13, the circuit cavity 13 is located below the flow cavity 11, a partition 15 is arranged between the circuit cavity 13 and the flow cavity 11, the storage tank 12 is arranged on one side of the partition 15 close to the flow cavity 11, and the vibration motor 31 is located in the circuit cavity 13 and is closely attached to one side of the partition 15 close to the circuit cavity 13. The vibration motor 31 is closely attached to the spacer 15, and the vibration effect of the vibration motor 31 on the magnetic medium can be improved.

The vibration motor 31 has a gap with the lower cover plate 42 to reduce vibration of the lower cover plate 42 and to allow most of the vibration energy to be used for vibration of the magnetic medium.
The posture detecting sensor is fixed with respect to the base 10 and is for detecting a spatial posture of the base 10, and is electrically connected to the circuit board 32. The posture detecting sensor is for detecting a spatial posture of the base 10, and may be a gyroscope, for example. The controller controls the operation of the first and second electromagnetic assemblies 21 and 22 according to the feedback signal of the posture detection sensor. If the base 10 is in a horizontal state, the two electromagnetic assemblies are not operated. If one end of the base 10 in the first direction X is sunk, the first electromagnetic assembly 21 or the second electromagnetic assembly 22 operates to attract the magnetic medium to move toward the higher end to adjust the posture of the base 10. In fact, during the descent of the curtain lower rail 94, the posture change of the base 10 tends to be complex, and the controller controls the two electromagnetic assemblies to work together in real time, so as to attract the magnetic medium to move along the first direction X, and realize the dynamic balance of the center of gravity of the base 10. The controller may be a microprocessor MCU provided on the circuit board 32 along with the attitude detection sensor. In some cases, a gesture detection sensor may be omitted, and a control switch electrically connected to the controller may be additionally provided, so that the user controls the operation of the two electromagnetic assemblies through the control switch according to the observed skew condition of the curtain lower rail 94.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
