[0012] Please refer to FIGS. 1-5. FIG. 1 is a schematic overall structural diagram of a Christmas tree mounting seat of the present application, FIG. 2 is a front view of the Christmas tree mounting seat of the present application, FIG. 3 is a sectional view along a direction AA in FIG. 2, FIG. 4 is an exploded structural view of a first plug-in base and a second plug-in base, and FIG. 5 is a partial exploded structural view of a first plug-in base and a second plug-in base in another embodiment.

[0013] The present application discloses a Christmas tree mounting seat, which improves a traditional structure, leading to a reduced overall volume and a more simplified and compact structure. The Christmas tree mounting seat includes a base 1 and a supporting base 2 connected to each other. The base 1 and the supporting base 2 define an accommodating cavity. A first flange 11 and a second flange 21 extending to the accommodating cavity are provided on the base 1 and the supporting base 2, respectively. A first plug-in base 3 and a second plug-in base 4 engaged with each other along an axial direction are provided in the accommodating cavity. The first plug-in base 3 and the second plug-in base 4 are rotatably sandwiched between the first flange 11 and the second flange 12, and may rotate with respect to the base 1 and the supporting base 2 along a circumferential direction. A cavity is provided in the first plug-in base 3 and the second plug-in base 4. An end of the second plug-in base 4 protrudes from the supporting base 2, and a plug hole 41 communicated with the cavity is provided on the end of the second plug-in base 4.

[0014] When in use, a bottom of a trunk of a Christmas tree is able to insert into the plug hole 41 and extends into the cavity. A driving source is provided in the accommodating cavity. The driving source drives the first plug-in base 3 to rotate, and the first plug-in base 3 drives the second plug-in base 4 to rotate, thereby driving the Christmas tree to rotate accordingly.

[0015] In order to enhance smoothness of rotation, reduce wear between structures, and minimize noise generated during rotation, a plurality of first rolling elements 6 and a plurality of second rolling elements 7 are provided in the accommodating cavity. In some embodiments, the plurality of first rolling elements 6 and the plurality of second rolling elements 7 have a variety of structural forms, and in this embodiment, both are spherical in shape. The plurality of first rolling elements 6 are provided between the first flange 11 and the first plug-in base 3 in a rolling manner, the plurality of second rolling elements 7 are provided between the second plug-in base 4 and the second flange 21 in a rolling manner.

[0016] An engagement mechanism of the first plug-in base 3 and the second plug-in base 4 have a variety of structural forms. In this embodiment, a plurality of snap-in protrusions 31 are provided on the first plug-in base 3 protruded to the second plug-in base 4 along a circumferential direction, a snap-in slot 42 corresponding to each snap-in protrusion of the plurality of snap-in protrusions 31 is provided on the second plug-in base 4 along a circumferential direction. In order to prevent a separation of the first plug-in base 3 and the second plug-in base 4 during rotation, a plurality of position-limiting ribs 9 are provided on the first plug-in base 3 or the second plug-in base 4 along a circumferential direction. The plurality of position-limiting ribs 9 extend along an axial direction and are configured to enhance a structural strength of the first plug-in base 3 or the second plug-in base 4. The plurality of position-limiting ribs 9 abut against an outer wall of the second plug-in base 4 or a first plug-in base 3 after protrude from the first plug-in base 3 or the second plug-in base 4, thus limiting a relative position of the first plug-in base 3 and the second plug-in base 4.

[0017] The driving source drives the first plug-in base 3 in a variety of ways. In this embodiment, a meshing tooth 32 is provided on the outside of the first plug-in base 3 away from the second plug-in base 4 along a circumferential direction. The driving source includes a motor 51 and a main gear 52 driven by the motor 51. The motor 51 is arranged at a bottom of thesupporting base 2. The main gear 52 is meshed with the meshing tooth 32. When the motor 51 is powered on, the motor 51 drives the main gear 52 to rotate, the main gear 52 drives the first plug-in base 3 to rotate through meshing, thereby driving the Christmas tree to rotate through the second plug-in base 4.

[0018] A plurality of reinforcing ribs 33 extending along an axial direction are provided on an inner wall of the supporting base 2. The plurality of reinforcing ribs 33 are arranged at intervals along a circumferential direction, thus enhancing a structural strength of the supporting base 2 and preventing deformation.

[0019] The trunk of the Christmas tree is mated with the plug hole 41 through the plug-in element 8, the plug-in element 8 is hollowed inside for the trunk insertion, and a plurality of first abutting ribs 81 abutting against the Christmas tree are provided along a circumferential direction on an inner wall of the plug-in element 8, thus fixing the plug-in element 8 to the trunk. In order to ensure that the trunk is able to insert into the plug-in element 8 accurately and quickly, an inclined first guiding surface 81A is provided on a top end of each first abutting rib of the plurality of first abutting ribs 81, a bottom of the trunk is able toslide into the plug-in element 8 along the first guiding surface 81A, and the gap between the bottom of the trunk and the first guiding surface 81A becomes progressively smaller during insertion of the bottom of the trunk. A plurality of second abutting ribs 82, which are in interference fit with the plug hole 41, are provided along a circumferential direction on an outer wall of the plug-in element 8, enabling the first plug-in base 3 to drive the plug-in element 8 to rotate together during rotation. Similarly, in order to facilitate an insertion of the plug-in element 8 into the plug hole 41, an inclined second guiding surface 82A is provided on a bottom end of each second abutting rib of the plurality of second abutting ribs 82, and the gap between the bottom of the second guiding surface 82A and the plug hole 41 becomes progressively smaller during the insertion of the plug-in element 8 into the plug hole 41.

[0020] A plurality of insertion slots 12 are evenly and spaced apart along a circumferential direction on a periphery of the base 1. Each insertion slot of the plurality of insertion slots 12 extends radially along the base 1, and is configured to be engaged and mated with a supporting leg 10. The supporting leg 10 extends radially outward and is in contact with a ground, thus improving a stability of the Christmas tree mounting seat. A structure of the supporting leg 10 have a variety of structural forms, which is the prior art in this technical field and will not be further elaborated here.

[0021] The Christmas tree typically requiresa large number of decorations to enhance an overall aesthetic appearance, and the most common decoration isa light string. In order to ensure that a wire of the light string is not overstretched and snapped during a rotation of the Christmas tree, it is essential to arrange a wiring path rationally. Two ends of the wire 110 are a first end 111 and a second end 112. A light string power supply connector or a light string power socket is provided on the first end 111, which is configured to be electrically connected to the light string by plugging. The second end 112 passes through a perforation 45 on the second plug-in base 4 into the cavity, and then passes through a bottom of the first plug-in base 3 and exits through the base 1. A power plug is provided on the second end 112, which is configured to be electrically connected to an external power supply. A controller may be connected in series to the wire 110 to control a light emitting effect of the light string.

[0022] When the first plug-in base 3 and the second plug-in base 4 rotate, the wire 110 moves within a small range along with the second plug-in base 4 and rotates in the perforation 45. This ensures a conductivity of the wire 110 while providing it with a certain degree of freedom. Thus, it avoids a problem seen in traditional setups where a wire wound around an exterior of the base 1 would get further entangled around the base 1 during rotation, leading to increasingly tight pulling.

[0023] In traditional artificial Christmas trees, a control switch for rotation is usually installed on a mounting seat. However, since the mounting seat is usually located at a bottom of a central axis of the Christmas tree, when branches are spread out, an outer diameter of the bottom of the tree increases. Due to a small size of the mounting seat, users must crawl under the Christmas tree to press the control switch. This increases difficulty of operating the control switch for users, and the rotating Christmas tree poses a risk of injury to users, resulting in lower safety.

[0024] In another embodiment, a control circuit board is further included. The control circuit board is electrically connected to the driving source. A length of the snap-in protrusion 31 along a circumferential direction is smaller than a length of the snap-in slot 42 along a circumferential direction, allowing a certain relative rotation of the first plug-in base 3 and the second plug-in base 4 along a circumferential direction. A first conductive block 34 is provided on an end surface of the snap-in protrusion 31 located on a front side of a rotation direction. A second conductive block 43 corresponding to the first conductive block 34 is provided on the snap-in slot 42. The first conductive block 34 and the second conductive block 43 are electrically connected to a positive terminal and a negative terminal of the control circuit board, respectively, and are connected in series to the driving source.

[0025] Taking an example of the first plug-in base 3 rotating clockwise to drive the Christmas tree. When the power supply is connected, the first conductive block 34 and the second conductive block 43 remain separated, and the driving source is disconnected and not activated. At this time, the trunk of the Christmas tree rotates counterclockwise through moving structures such as branches. The trunk drives the second plug-in base 4 to rotate counterclockwise, and the second conductive block 43 moves towards the first conductive block 34 until the second conductive block 43 is in contact with and abutted against the first conductive block 34. At this point, a circuit is connected, and the driving source is energized and activated. The first plug-in base 3 is rotated clockwise through the main gear 52, the first plug-in base 3 drives the second plug-in base 4, causing the trunk to rotate clockwise as well. In this process, the first conductive block 34 and the second conductive block 43 remain in abutment, thus ensuring a stability of a circuit connection.

[0026] To make it easier to turn off a rotation function of the Christmas tree, a first magnetic block 35 is provided on an end surface of the snap-in protrusion 31 located at a rear side of the rotation direction. A second magnetic block 44 corresponding to the first magnetic block 35 is provided on the snap-in slot 42. Taking an example of the first plug-in base 3 rotating clockwise to drive the Christmas tree. When it is necessary to pause a rotation of the Christmas tree, a clockwise rotation of the trunk of the Christmas tree is accelerated by moving structures such as branches. The trunk then drives the second plug-in base 4 to rotate clockwise at an accelerated rate, causing the second conductive block 43 to separate and move away from the first conductive block 34 until the first magnetic block 35 and the second magnetic block 44 are connected to each other. This disconnects the circuit and turns off the driving source, keeping the first conductive block 34 and the second conductive block 43 separated, as shown in FIG. 4, thus preventing the driving source from being restarted due to accidental contact.

[0027] In addition, when a plurality of snap-in protrusions 31 are provided, the first conductive block 34 and the first magnetic block 35 are provided on opposite sides of the same snap-in protrusion 31 in the rotation direction, or provided on opposite sides of the differentsnap-in protrusion 31 in the rotation direction.

[0028] The Christmas tree mounting seat of the present application, by rationally designing a structure of the mounting seat, ensures the rotation of the Christmas tree while making an overall structure of the mounting seat simpler and more compact. This significantly reduces a volume of the mounting seat, thereby enhancing an aesthetic appeal of the Christmas tree.
