The present application discloses a smart Christmas tree with self-adaptive lighting, which includes a first trunk, a first separated branch, a second trunk, a second separated branch, a third trunk and a third separated branch. Wherein, when it is determined that a first angle between the first separated branch and the first trunk is within a first preset range, a first light string is controlled to light up. When it is determined that a second angle between the second separated branch and the second trunk is within a third preset range, a second light string is controlled to light up. When it is determined that a third angle between the third separated branch and the third trunk is within a fifth preset range, a third light string is controlled to light up.

A clamping base includes a housing, a supporting body disposed in the housing, and clamping members and a locking member that are mounted on the supporting body. A placement groove configured to accommodate a placed object is provided in the supporting body, a plurality of sliding grooves are obliquely provided on an inner wall of the placement groove, the sliding grooves extend toward a center of the placement groove from top to bottom, the clamping members are circumferentially disposed in the placement groove, and sliders capable of sliding along the sliding grooves are disposed on the clamping members; the locking member is connected to an upper part of the supporting body; a ring-shaped pressing ring is disposed on a top of the locking member; and an elastic member capable of pushing the clamping member to return is further disposed between the clamping member and the supporting body.

Provided is a rotatable artificial tree. The rotatable artificial tree includes an artificial tree body, a rotatable electric assembly and a supporting base. The artificial tree body is provided with decorative light strings and a trunk, and the supporting base is provided with a driving motor. The rotatable electric assembly includes a rotating shaft core which is connected with a power output shaft of the driving motor in a non-rotating manner and vertically arranged. The rotating shaft core is connected with the trunk in a driving manner. A conductive ring mounting sleeve which rotates synchronously with the rotating shaft core sleeves the periphery of the rotating shaft core. At least two metal conductive rings which are arranged at an insulating interval from top to bottom and are respectively in a circular ring shape sleeve the periphery of the conductive ring mounting sleeve.

The present disclosure relates to a rotary artificial tree. The rotary artificial tree includes an artificial tree body, a rotary power connection assembly and a supporting base, where two ends of the rotary power connection assembly are respectively connected to the artificial tree body and the supporting base, the artificial tree body is provided with a light source electrically connected to the supporting base, and the supporting base is provided with a driving motor; the rotary power connection assembly includes a rotating shaft core and a conductive structure sleeved at the periphery of the rotating shaft core. Through the above structural design, the present disclosure has the advantages of novel design, simple structure and convenient assembly.

The invention discloses a Christmas tree stand, which comprises a rotating seat, a fixing seat, a driving mechanism and a plurality of supporting legs. The middle and lower ends of the rotating seat are inserted into an internal cavity of the fixing seat, the driving mechanism is fixedly installed in the internal cavity of the fixing seat, so that the rotating seat and the driving mechanism are coaxially arranged, and the driving mechanism is connected to the rotating seat, enabling the rotating seat and the Christmas tree to rotate synchronously. Since the rotating seat and the driving mechanism are coaxially assembled in the internal cavity of the fixing seat, transmission gears and annular external teeth are always in an ideal engaged state; space can be fully utilized to closely integrate the driving mechanism with the rotating seat.

The present application discloses a smart Christmas tree with self-adaptive lighting, which includes a first trunk, a first separated branch, a second trunk, a second separated branch, a third trunk and a third separated branch. Wherein, when it is determined that a first angle between the first separated branch and the first trunk is within a first preset range, a first light string is controlled to light up. When it is determined that a second angle between the second separated branch and the second trunk is within a third preset range, a second light string is controlled to light up. When it is determined that a third angle between the third separated branch and the third trunk is within a fifth preset range, a third light string is controlled to light up.
