It should be noted that the above preferred embodiments are only used for illustrating the principle of the present application, and are not intended to limit the protection scope of the present application. Without departing from the principles of the present application, those skilled in the art can adjust the setting manner, so that the present application can be applied to more specific application scenarios.

For example, in an alternative embodiment, although the above-mentioned embodiment provides only one embodiment for the hitching mechanism 3 and the driving roller assembly 4, it should be understood by those skilled in the art that the contribution of the present application to the prior art is reflected in the detachable arrangement between the first casing 1 and the second casing 2, and therefore, in the case of adopting the detachable arrangement of the first casing 1 and the second casing 2 of the present application, it would be within the protection scope of the present application to use other forms of hitching mechanism 3 and driving roller assembly 4. For example, the coupling mechanism 3 may also take a form suitable for a roman bar or an i-bar, which may be provided in the first housing 1 or may be provided independently of the first housing 1. The driving roller assembly 4 can adopt a single-motor driving single roller form, and also can adopt a single-motor driving multi-roller form or a multi-motor driving multi-roller form. In addition, the position relationship between the driving roller assembly 4 and the hanging mechanism 3 can be adjusted as long as the hanging mechanism 3 is hung on the curtain rail and the driving wheel 42 of the driving roller assembly 4 is abutted on the lower side surface of the curtain rail.

For example, in an alternative embodiment, although the above embodiment is described with the first housing 1 having the recess 13 formed at the bottom and the second housing 2 having the boss 22 formed at the top, the arrangement is not exclusive and can be modified by one skilled in the art to suit more specific application scenarios. For example, the bottom of the first housing 1 may be formed with a boss 22, the top of the second housing 2 is formed with a groove 13, the first coupling member 12 is disposed on the boss 22, and the second coupling member 21 is disposed in the groove 13. Of course, the boss 22 and the groove 13 may not be provided, but the first coupling member 12 is directly provided at the bottom of the first housing 1 and the second coupling member 21 is provided at the top of the second housing 2.

As another example, in another alternative embodiment, although the above embodiment is described in conjunction with the permanent magnet being disposed on the side of the groove 13 facing the inside of the first housing 1, the magnetic metal being disposed inside the boss 22, and both being disposed, this arrangement is not a constant one and can be modified by those skilled in the art. For example, a permanent magnet may be provided on the side of the recess 13 facing the second housing 2, and/or a magnetic metal may be provided outside the boss 22, or the like. For another example, the number and the arrangement position of the first housing 1 and the second housing 2 may also be adjusted, as long as the adjusted technical scheme meets the requirement of the connection between the first housing 1 and the second housing 2.

As still another example, in another alternative embodiment, although the above embodiment is described in conjunction with the first connecting member 12 being a permanent magnet and the second connecting member 21 being a magnetic metal, it is apparent that a person skilled in the art can freely adjust the specific forms of the first connecting member 12 and the second connecting member 21 if one of the first connecting member 12 and the second connecting member 21 is a permanent magnet and the other is a permanent magnet or a magnetic metal.

As another example, in another alternative embodiment, although the connector described above is described in conjunction with a pogo pin connector, one skilled in the art could modify it, for example, one skilled in the art could use a pogo pin connector, a magnetically attractive connector, or the like instead of a pogo pin connector. In addition, in the above embodiment, the male end 61 of the connector is disposed on the first housing 1, and the female end 62 of the connector is disposed on the second housing 2, but those skilled in the art will know that the positions of the male end and the female end can be changed, and the electric connection between the male end and the female end is not affected after the change.

For another example, in another alternative embodiment, although the above embodiment is described in conjunction with the charging port 8 being a type-C interface, this is not intended to limit the scope of the present application, and in other possible embodiments, those skilled in the art may substitute other possible charging interfaces such as type-A, type-B. In other embodiments, a person skilled in the art may charge the battery by wireless charging instead of providing the charging port 8. That is, a wireless charging coil is provided in the second housing 2, and the wireless charging coil is electrically connected to the power supply module 5. The principle of wireless charging is conventional means, and is not described in detail. Of course, when possible, a person skilled in the art may also provide the charging port 8 and the wireless charging coil at the same time on the second housing 2 to meet different charging requirements of users.

For another example, in another alternative embodiment, although the above embodiment is described in connection with the power supply module 5 including the power supply control board 51 and the rechargeable battery 52, and the main control board 53 is disposed in the first housing 1, the arrangement may be adjusted by those skilled in the art as long as the adjusted technical solution can supply power to the driving mechanism 41 by using the power supply module 5. For example, the power supply control board 51 may be integrated with the main control board 53 and then disposed in the second housing 2, that is, the power supply module 5 includes the main control board 53 and the rechargeable battery 52, the rechargeable battery 52 is electrically connected to the main control board 53, and the main control board 53 is electrically connected to the driving mechanism 41 through a connector. For another example, instead of the rechargeable battery 52, a battery compartment may be provided in the second housing 2 for accommodating a dry battery, and the dry battery is connected to a battery control board or main control board 53 to supply power to the driving mechanism 41.

Of course, the above alternative embodiments, and the alternative embodiments and the preferred embodiments can also be used in a cross-matching manner, so that a new embodiment is combined to be suitable for a more specific application scenario.

In addition, no matter how the card slot and the buckle are arranged, the elastic button 23 is not arranged on the second shell 2, but the elastic deformation of the material of the second shell 2 is relied on when the user presses the second shell 2, so that the buckle is separated from the card slot.

Furthermore, on the premise of providing the elastic button 23, a person skilled in the art may also adjust the elastic button 23, for example, a form of button + spring independent from the second housing 2 is used to replace the cutting and forming manner in the drawings. Specifically, a counter bore may be formed in a side surface of the second housing 2, a sliding groove is formed in an inner wall of the counter bore, a button with a buckle is additionally provided, a sliding block is arranged on the button, and the sliding block is clamped into the sliding groove, so that the button slides in the sliding groove and does not separate from the sliding groove. Then a compression spring is arranged between the button and the counter bore, when the button is pressed down, the buckle moves towards the inside of the second shell, and the compression spring is compressed to store elastic potential energy; when the button is loosened, the compression spring releases elastic potential energy to drive the button to rebound to the clamping position.
